The first water inlet bin 5 and the second water inlet bin 6 play a role in double insurance, ensure that the protective air bag 12 can be smoothly ejected, and solve the problem that the patrol car 18 is difficult to salvage when immersed in water.
In this embodiment, the dehumidifying mechanism includes a first convection hole and a second convection hole respectively disposed on two opposite sidewalls of the housing; a heating and dehumidifying element 21 is arranged in the first convection hole; a negative pressure fan 20 is arranged in the second convection hole.
As shown in fig. 5 and 6, the heating and dehumidifying element 21 is connected to one end of the inner side of the first convection hole through a rotating shaft 201, a first conductive sheet 202 is disposed at one end of the heating and dehumidifying element 21 away from the rotating shaft 201, and a second conductive sheet 203 is disposed at the other end of the inner side of the first convection hole; the negative pressure fan 20 is connected with one end of the inner side of the second convection hole through a rotating shaft 201, a first conductive sheet 202 is arranged at one end of the negative pressure fan 20 away from the rotating shaft 201, and a second conductive sheet 203 is arranged at the other end of the inner side of the second convection hole; when the first conductive sheet 202 contacts with the second conductive sheet 203, the heating and dehumidifying member 21 or the negative pressure fan 20 can be powered.
The first convection hole and the second convection hole form a pair of oppositely arranged convection holes 22, so that the stability and the persistence of wind direction are ensured; the negative pressure fan 20 is a miniature negative pressure fan, and the heating dehumidifying part 21, the negative pressure fan 20 and the rotating shaft 201 all adopt the prior art, and are not described herein.
In this embodiment, as shown in fig. 3, a first humidity detecting member is further disposed in the first convection hole; the first humidity detection piece is clamped in the first convection hole, so that the first convection hole is closed, and the first humidity detection piece is used for detecting humidity in the shell; the first humidity detection member is a humidity observation box 19.
In this embodiment, as shown in fig. 3, a second humidity detecting member is further disposed in the second convection hole; the second humidity detection piece is clamped in the second convection hole, so that the second convection hole is closed, and the second humidity detection piece is used for detecting the humidity in the shell; the second humidity detecting member is a humidity observation box 19.
As shown in fig. 4, a placement groove 191 is provided in the humidity observation box 19, and a humidity detection object, which is anhydrous copper sulfate powder 192, is provided in the placement groove 191; a transparent observation window is arranged on one side of the humidity observation box 19 facing outwards, and the transparent observation window is heat-resistant transparent glass 194; two ends of one side of the humidity observation box 19 facing outwards are respectively provided with a magnetic attraction piece 193, and the magnetic attraction pieces 193 are used for enhancing the adsorption force of the humidity observation box 19 on the convection holes 22; the top of the placement tank 191 is provided with an opening for containing new anhydrous copper sulfate powder 192 and for discharging the anhydrous copper sulfate powder 192 that completes the reaction.
The working principle of the dehumidifying mechanism is as follows:
When water vapor enters the interior of the inspection vehicle 18, the white anhydrous copper sulfate powder 192 in the humidity observation box 19 in the inspection vehicle 18 is moistened, so that the anhydrous copper sulfate powder 192 is changed into copper sulfate pentahydrate, and the color of the anhydrous copper sulfate powder 192 is changed from white to blue. The inspection staff can observe the color change of the anhydrous copper sulfate powder 192 through the transparent observation window of the humidity observation box 19, after the inspection staff finds that the color change is blue, the two humidity observation boxes 19 are respectively taken out of the convection holes 22, at the moment, the heating and dehumidifying piece 21 and the negative pressure fan 20 in the inspection vehicle 18 are respectively rotated to the corresponding openings of the convection holes 22 around the rotating shaft 201, at the moment, the first conductive sheet 202 is contacted with the second conductive sheet 203, so that the heating and dehumidifying piece 21 and the negative pressure fan 20 are electrified and start to work. As shown in fig. 7, when the negative pressure fan 20 draws air, the air in the inspection vehicle 18 forms negative pressure, so that the air outside the inspection vehicle 18 is forced to flow through the heating dehumidifying element 21, the air is heated by the heating dehumidifying element 21 and becomes hot air, and the hot air passes through the interior of the inspection vehicle 18 and takes away water vapor in the inspection vehicle 18, thereby realizing the dehumidification of the interior of the inspection vehicle 18. After dehumidification is completed, the inspector re-puts new anhydrous copper sulfate powder 192 into the humidity observation box 19, re-clamps the humidity observation box 19 into the convection hole 22, and then re-closes the convection hole 22.
The dehumidification mechanism can effectively dehumidify the interior of the inspection vehicle 18, and avoids corrosion and mildew of internal parts caused by water vapor gathered in the inspection vehicle 18.
In this embodiment, the photographing mechanism includes a plurality of high-definition cameras 180, where the high-definition cameras 180 are used to collect image information of the communication optical cable.

S1, when the inspection vehicle 18 walks according to a preset route, the shooting mechanism is used for collecting and transmitting image information of a communication optical cable in real time;
S2, the image receiving module receives image information acquired by the shooting mechanism and transmits the image information to the image processing module; and the image processing module identifies target characteristics in the image information and classifies the target characteristics to obtain a defect classification result of the communication optical cable. Wherein the target features include breakage, and decay defects of the communication cable.
In this embodiment, the step S2 specifically includes:
S21, receiving the image information, extracting a region containing a target body from the image information by using a multi-scale fusion method of multi-level segmentation regions, and taking the region as a candidate window; wherein the target body is a communication optical cable selected during patrol;
S22, judging the positioning deviation of the candidate window, and correcting the positioning deviation if the positioning deviation exceeds a set threshold value, so as to prepare for subsequent operation; wherein the threshold is set according to a specific definition of the positioning deviation;
S23, obtaining a part of the super pixel crossing a candidate window based on an image segmentation method of the super pixel, and filling the part of the super pixel crossing the candidate window into the candidate window;
S24, extracting the characteristics of the candidate window by using a convolutional neural network, and performing category training according to the extracted characteristics to obtain an SVM linear classifier;
S25, classifying the defect categories of the communication optical cable by using an SVM linear classifier to obtain a defect classification result of the communication optical cable.
In this embodiment, in step S22, the positioning deviation of the candidate window is determined according to the degree of inclusion of the super pixel in the candidate window.
The inspection method for the overhead power communication optical cable improves the accuracy of feature extraction and can obtain more reliable detection results.
