Description
Technical field
The utility model relates to cinema projection window structures.
Background technique
In existing movie theatre, projection port is typically provided between movie theater and projection booth, is widely used in movie theatre, movie theater and
Sound insulation and fireproof are played the role of in isolation between projection booth.But in use for some time, on projection port transparent glass
Dust can be fallen, it is inconsistent additionally, due to projection room and movie theater temperature, it is easy to cause on transparent glass and forms water mist, dust and water
Mist, which is clipped together, greatly reduces transparent glass light transmittance, is substantially reduced so that brightness and contrast reduces.
Summary of the invention
The technical problem to be solved by the present invention is to provide cinema projection window structures, for solving movie theatre transparent glass
Because of the problem of dust and water mist influence glass transmission rate.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
Cinema projection window structure, including wall and projection port, window is interior to be equipped with square tube, and square tube is located in movie theatre movie theater
One end and transparent glass are tightly connected, and square tube other end connects bucket shape housing, and housing is close by bellows and projector camera lens
Envelope connection, forms sealing structure outside projector camera lens by glass, square tube, housing and bellows, in transparent glass upper and lower ends
It is respectively equipped with a discharge pipe, multiple nozzles are communicated on each discharge pipe, each jet nozzle direction is towards light transmission glass
Glass, discharge pipe one end are connected to after passing through wall with projector refrigerator pipe.
Transparent glass is that inclination is connected in square tube.
Housing upper end is connected to discharge pipe by scavenging air pipe, and housing lower end is connected to exhaust pipe, in scavenging air pipe, exhaust pipe and outlet air
Valve is mounted on pipe.
Housing and square tube are all made of light-proof material and are made.
Plug is filled with sound-proof material between square tube and window.
The beneficial effects of the utility model are:
1, the air being sent in projector is to be cleaned, drop the cold air after gently dried, using the cold air to saturating
Light glass is purged, and dust and water mist on transparent glass are removed, it is avoided to influence glass transmission rate, guarantees projector projection
When clarity.
2, a closed structure is formed outside projector camera lens by glass, square tube, housing and bellows, on the one hand protection is put
Film projector camera lens prevents camera lens to be stained with ash, on the other hand, can completely cut off the noise that projection room is transmitted to movie theater, prevent projection port from leaking
Light and light interference lead to bright decaying while reducing light loss.
3, the transparent glass of inclination connection can be avoided projector and issue beam orthogonal irradiation transparent glass, can incline
Foldback obliquely or downwards, avoids it from being directly reflected back on the camera lens of projector, reduces repeated reflection, prevents reflected light to screen
Influence.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the partial enlargement structural representation of the utility model,
Fig. 3 is the main view of the utility model,
Fig. 4 is the partial enlargement structural representation in Fig. 2 at A.
In figure: wall 1, projector 2, transparent glass 3, square tube 4, housing 5, bellows 6, discharge pipe 7, scavenging air pipe 8, sound insulation
Cotton 9, valve 10, projection port 11, camera lens 21, refrigerator pipe 22, clip 61, rubber pad 62, nozzle 71, exhaust pipe 81.
Specific embodiment
Before making description to the utility model, projector 2 used in movie theatre is made and is further described, cinema projector is adopted
With Sony's SRX-R810P projector, needs to be filled with temperature into projector from refrigerator pipe 22 when which works and be taken the photograph for 5 to 10
Family name's degree, humidity are 20% or so cold air, and require to be cleaned the cleaned dust of device into body cold air.
The utility model is made below and being further described, as shown in fig. 1 to 4, cinema projection window structure, including sound insulation
Wall 1 and projection port 11, window 11 is interior to be equipped with square tube 4 made of stainless steel, and square tube 4 is located at one end in movie theatre movie theater and is equipped with thoroughly
Light glass 3(float glass), the gap between transparent glass 3 and square tube 4 is filled out using the plug of rubber pad 62, and blend compounds hydropexis is wanted
It asks and is sealed between transparent glass 3 and square tube 4,4 other end of square tube connects 5 one end of housing made of bucket shape stainless steel, and housing 5 is another
One end connects 6 one end of bellows, and 6 other end of bellows is connected by rubber pad 62 and the sealing of clip 61 and projector camera lens 21
Connect, the effect of bellows 6 is: because bellows 6 is flexibility, thus can be convenient by bellows 6 and projector camera lens
21 docking；Sealing structure is formed outside projector camera lens 21 by glass 3, square tube 4, housing 5 and bellows 6, on transparent glass 3
Lower both ends are respectively equipped with a discharge pipe 7, and multiple nozzles 71 are communicated on each discharge pipe 7, as shown in figure 4, nozzle 71 is
One conical pipeline has angle a between 3 plane of 71 axis of nozzle and glass, so that each 71 jet direction of nozzle is equal
Towards transparent glass 3,7 one end of discharge pipe is connected to after passing through wall 1 with projector refrigerator pipe 22, is filled between discharge pipe 7 and wall 1
It is filled with sound-proof material 9.After projector booting, two-way is divided by the cold air that refrigerator pipe 22 is discharged, enters be passed through projection all the way
In addition machine enters in discharge pipe 7 all the way, the cold air that discharge pipe 7 is discharged purges transparent glass 3, removes the ash on transparent glass 3
Dirt and water mist avoid it from influencing 3 light transmittance of glass, guarantee clarity when projector projection；Due to external out in cool air hose
Air hose 7, to being shunted into 2 cold air of projector, in order to ensure the normal air feed of projector, thus to the wind speed of cool air hose into
It has gone and has properly increased, such as: former cool air hose wind speed is 10m/s, is now improved to 12m/s.
Transparent glass 3 is that inclination is connected in square tube 4.The transparent glass 3 of inclination connection can be avoided projector and issue light
Beam vertical irradiation transparent glass 3, can tilt upward or downward foldback, it is avoided directly to be reflected back the camera lens of projector 21
On, repeated reflection is reduced, influence of the reflected light to screen is prevented.
5 upper end of housing is connected to discharge pipe 7 by scavenging air pipe 8, and 5 lower end of housing is connected to exhaust pipe 81, in scavenging air pipe 8, exhaust
Valve 10 is mounted on pipe 81 and discharge pipe 7.At the beginning of the sealing structure being made of glass 3, square tube 4, housing 5 and bellows 6
When secondary installation or damaged appearance, so that outside air enters in sealing structure, air inlet pipe and scavenging air pipe 8 at this moment can be opened
On valve 10, close discharge pipe 7 on valve 10, allow refrigerator pipe 22 be discharged cold air enter in sealing structure, with squeeze
Former air in sealing structure out, it is ensured that it is dustless in sealing structure, avoid dust from being infected with camera lens 21.
Housing 5 and square tube 4 are all made of light-proof material and are made.Preventing 11 light leakage of projection port and light from interfering causes light to decline
Subtract while reducing light loss.
Plug is filled with sound-proof material 9 between square tube 4 and window 11.This structure can completely cut off projection room and be transmitted to making an uproar for movie theater
Sound.
