Description

Photovoltaic cleaning machine

Technical Field

The utility model relates to the technical field of cleaning of photovoltaic power stations, in particular to a photovoltaic sweeper.

Background

The distributed photovoltaic power station is characterized in that the installed capacity of the power station is small but the number is large, the power station is built in a scattered (discontinuous) manner, various facility barriers (lighting belts, ventilating fans, chimneys, exhaust buildings, air-conditioning external machines, water tanks and the like) are arranged on the roof, meanwhile, the photovoltaic module square matrix in each power station is also small in capacity (small in plate number) of the photovoltaic module array monomers, but the number of the monomers is large, and the photovoltaic module array monomers are distributed in a scattered and irregular manner. In this case, the cleaning equipment, the man-machine mode, the operation mode and the business mode involved in the component cleaning business of the conventional centralized large-scale ground photovoltaic power plant have not been applied. At present, aiming at the cleaning operation of the photovoltaic module of the distributed roof photovoltaic power station, the working mode selected in the industry mostly adopts a mode of entrusting cleaning by a third party. In order to reduce the cost, the contractor of the cleaning operation adopts a manual and electric cleaning tool, and a water washing mode is generally adopted. The disadvantage of this sweeping approach is that the overall sweeping efficiency (speed) is low, the personnel effort is high (and unfortunately expensive), and a water source is required. Remote control type portable photovoltaic automatic cleaning equipment appears in the market, equipment cost is cheaper than a full-automatic intelligent photovoltaic cleaning robot, and contractors can accept the equipment. However, such portable automatic cleaning devices have several drawbacks that limit the widespread use of such cleaning devices in roofing photovoltaic power plant cleaning:

1. The dry cleaning machine type is easy to cause dust raising in a large area, the wind speed is higher than that of the ground on a roof with a relatively dense photovoltaic module, and the dust raising in a large area is easy to cause cross contamination in a large area;

2. The water-washing type cleaning machine needs a large amount of water, water taking is a difficult problem and a high-power water pump (heavy and power or gasoline is needed) is needed; these problems require more human resources to be consumed to solve, thereby increasing costs;

3. There are two types of dry cleaning models that integrate the vacuum and dust collection functions: (1) The cost of the monomer equipment of the low-power lithium battery model is slightly high, the cleaning speed is very low, and a plurality of monomer equipment are required to work simultaneously, so that the comprehensive cost is very high; (2) The single-body equipment of the high-power commercial motor type has very high cost, high power consumption and heavy equipment (because of adopting a dust filter bag, the high-power motor and large-area heat dissipation).

(2) The controller controls the cleaning driving motor to start, the cleaning driving motor drives the driving shaft 53 of the mobile cleaning mechanism 5 to rotate at a high speed through the belt transmission mechanism 9, at the moment, the row brush 59 continuously scrapes the surface of the photovoltaic module to scrape dust, an air inlet is formed at the bottom end of the end plate 52 without the rubber sealing strip 56, air is sucked into the mobile cleaning mechanism 5 through the air inlet, the dust is driven by the spiral rolling brush spiral blade 58 to form dust flow, then the dust flow enters the guide cover 54 to be accelerated, and is sprayed to enter the collecting pipe 55 to be collected, and finally the dust is conveyed to the dynamic dust separation mechanism 6 through the negative pressure conveying pipeline 10;

(3) The dust flow enters the interior of the tank 61 from the inlet pipeline 66 and passes through the conical ring filter screen 63 to enter the peripheral area of the dust hood 64, the dirt with larger particles in the air flow is blocked by the conical ring filter screen 63 and falls to the bottom of the tank 61, and because the dust hood 64 is of a closed structure, the dust flow can only enter the three cyclone separators 65 through the three outer inlets 646 at the top end of the dust hood 64, at the moment, the dust flow moves downwards along the conical surface of the cyclone separators 65 while rotating at a high speed, when rotating to the ash discharge port 652, fine particles in the dust flow are counteracted by inertia and fall to the bottom of the tank 61 through the ash discharge port 652, the air flow is rebounded by the bottom of the tank 61, moves upwards and is output through the overflow outlet 68 on the cover 62, and finally is conveyed to the static dust separation mechanism 7 through the negative pressure conveying pipeline 10;

(4) The air flow enters the box body 71 from the air inlet 77, the air flow is enabled to enter between the two layers of partition plates 72 due to the blocking effect of the end parts of the two layers of partition plates 72, the lower layer electrostatic dust collection plate 73 between the two layers of partition plates 72 is used for carrying out electrostatic absorption on fine dust in the air flow, then the air flow is enabled to enter between the top plate of the box body 71 and the upper layer of partition plates 72, the upper layer electrostatic dust collection plate 73 between the top plate of the box body 71 and the upper layer of partition plates 72 is used for carrying out electrostatic absorption on the fine dust in the air flow again, so that most of fine dust in the air flow is absorbed and separated, then the dust flow is discharged through the air outlet 78 after being filtered further through the filter tube 711, and finally the clean air flow is discharged through the negative pressure fan 8, and the whole working flow is finished.

When the photovoltaic cleaning machine is used for a period of time, the sealing cover 62 of the dynamic dust separating mechanism 6 can be detached from the tank 61, then the conical ring filter screen 63 and the dust collecting cover 64 in the tank 61 are detached from the tank 61, so that the tank 61, the conical ring filter screen 63 and the dust collecting cover 64 are respectively cleaned, then the cleaning machine is reinstalled into the tank 61, and the sealing cover 62 is reinstalled into the top end of the tank 61; meanwhile, the strip-shaped sliding blocks 76 on the front panel of the box body 71 of the static dust separating mechanism 7 can be pulled out along the strip-shaped sliding rails 75, at the moment, the two partition plates 72 are pulled out simultaneously along with the front panel of the box body 71, then the partition plates 72 are taken down from the partition plate clamping grooves 79, the static dust collection plates 73 are taken down from the dust collection plate clamping grooves 710, and therefore the inside of the box body 71 and the partition plates 72 are cleaned, and static adsorption paper on the two sides of the static dust collection plates 73 is replaced. After cleaning, the dynamic dust separating mechanism 6 and the static dust separating mechanism 7 can be ensured to realize good dust removing function, thereby prolonging the service life of the utility model.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
