The camera body is installed in the upper cavity inside the housing. A lower cavity is provided in the housing below the upper cavity. The cleaning component includes a cleaning rod installed inside the housing. The cleaning rod has a hollow structure. A rubber cleaning plate is installed at one end of the cleaning rod near the lens of the camera main unit, and the rubber cleaning plate moves against the lens of the camera main unit. A driving mechanism is provided between the cleaning rod and the housing to drive the cleaning rod to move up and down reciprocally to clean the lens of the camera body.

[0006] The cleaning assembly includes a water tank installed at the bottom of the housing, and the water tank is connected to the lower cavity of the housing. A water pump is installed in the water tank, and a hose is connected between the water pump and the rubber cleaning plate. Multiple water spray holes are opened on one side of the cleaning rod near the rubber cleaning plate, and the multiple water spray holes are connected to the hollow inner cavity of the cleaning rod.

[0007] Preferably, the driving mechanism includes sliding grooves on both sides of the inner side of the housing, with a slider slidably connected in one of the sliding grooves and the slider connected to the cleaning rod. A lead screw is rotatably connected between the upper and lower sides of the inner cavity of one of the sliding grooves, and the slider is threaded onto the outside of the lead screw. A drive motor is installed on one side of the bottom of the housing, and the drive end of the drive motor rotates through the housing and is connected to the lead screw through a coupling.

[0008] Preferably, a plurality of heat dissipation plates are installed on the top of the inner cavity of the lower cavity, one end of each heat dissipation plate is inserted through the upper cavity, the other end of each heat dissipation plate extends into the water storage tank, and the bottom of each heat dissipation plate does not contact the bottom of the inner cavity of the water storage tank.

[0009] Preferably, all of the heat sinks are copper plates, and each of the heat sinks has multiple through holes.

[0010] Preferably, the housing on the lower side of the cleaning rod is provided with multiple water inlet holes, and all of the multiple water inlet holes are connected to the lower cavity. A baffle is installed on the inner wall of the housing on one side of the water inlet hole.

[0013] Preferably, a mounting plate is installed at the bottom of the water storage tank, and a second fixing bolt passes through the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model combines a drive mechanism, a rubber cleaning plate, a cleaning rod, a water tank, a water pump, a spray nozzle, and a hose. The drive mechanism moves the cleaning rod, which works in conjunction with the rubber cleaning plate to clean the lens of the camera body. During the movement of the cleaning rod, the water pump sprays cleaning water from the water tank through the hose and sprays it onto the lens of the camera body through the spray nozzle. This improves the cleaning effect of the rubber cleaning plate on the dust adsorbed on the lens of the camera body, thus ensuring the cleanliness of the lens surface of the camera body even under extreme conditions of high dust concentration. This prevents dust from causing blurry images captured by the camera body and affecting the accuracy of derrick inspection.

[0016] 2. This utility model combines a heat sink and through holes. When the camera body is working, the heat sink can dissipate the heat generated during operation to the upper cavity. The heat sink is placed in the cleaning water in the water tank, so the cleaning water in the water tank can cool the heat sink. At the same time, the through holes increase the heat dissipation area of ​​the heat sink, further improving the heat dissipation effect when the camera body is working.

[0017] 3. This utility model combines a water inlet and a filter screen. When water is sprayed from the spray nozzle to clean the lens of the camera body, the wastewater generated during cleaning flows back into the water storage tank through the water inlet and the lower cavity. Before the wastewater is recycled into the water storage tank, it is filtered by the filter element, thereby ensuring the cleanliness of the wastewater and preventing the spray nozzle from becoming clogged when the wastewater is recycled and reused.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A camera for inspecting a vertical shaft hoisting derrick, see [link / reference] Figures 1 to 6The system includes a camera body 2, a cleaning assembly, and a cleaning component. The camera body 2 is installed inside an upper cavity 12 within a housing 1. A lower cavity 13 is provided inside the housing 1 below the upper cavity 12. The cleaning assembly includes a cleaning rod 74 installed inside the housing 1. The cleaning rod 74 has a hollow structure. A rubber cleaning plate 75 is installed at the end of the cleaning rod 74 near the lens of the camera main unit, and the rubber cleaning plate 75 moves against the lens of the camera main unit. A drive mechanism is provided between the cleaning rod 74 and the housing 1. The cleaning mechanism is used to drive the cleaning rod 74 to move up and down reciprocally to clean the lens of the camera body 2. The cleaning assembly includes a water tank 3 installed at the bottom of the housing 1, and the water tank 3 is connected to the lower cavity 13 of the inner cavity of the housing 1. A water pump 5 is installed in the water tank 3. A hose 51 is connected between the water pump 5 and the rubber cleaning plate 75. The cleaning rod 74 has multiple water spray holes 76 on one side near the rubber cleaning plate 75, and the multiple water spray holes 76 are all connected to the hollow inner cavity of the cleaning rod 74.

[0027] During operation, the cleaning rod 74 is moved by the drive mechanism, which works in conjunction with the rubber cleaning plate 75 to clean the lens of the camera body 2. As the cleaning rod 74 moves, the water pump 5 sprays the cleaning water in the water tank 3 through the hose 51 and then sprays it onto the lens of the camera body 2 from the spray hole 76. This improves the cleaning effect of the rubber cleaning plate 75 on the dust adsorbed on the lens of the camera body 2, thus ensuring the cleanliness of the lens surface of the camera body 2 under extreme working conditions with high concentrations of dust. This prevents dust from causing blurry images captured by the camera body 2 and affecting the accuracy of the derrick inspection.

[0028] For details, see Figure 2 — Figure 4 and Figure 6 The driving mechanism includes sliding grooves 7 on both sides of the inner side of the housing 1. A slider 72 is slidably connected in one of the sliding grooves 7, and the slider 72 is connected to the cleaning rod 74. A lead screw 73 is rotatably connected between the upper and lower sides of the inner cavity of one of the sliding grooves 7. The slider 72 is threaded onto the outside of the lead screw 73. A drive motor 71 is installed on one side of the bottom of the housing 1. The drive end of the drive motor 71 rotates through the housing 1 and is connected to the lead screw 73 through a coupling. The drive motor 71 drives the lead screw 73 to rotate back and forth, thereby driving the rubber cleaning plate 75 to move back and forth up and down (the back and forth movement of the rubber cleaning plate 75 is achieved by the forward and reverse rotation of the drive motor 71. How the motor achieves forward and reverse rotation is a known technology and will not be described in detail here). This enables the reciprocating cleaning of the lens of the camera body 2, further improving the dust cleaning effect on the surface of the lens of the camera body 2.

[0029] Further, see Figure 2Multiple heat dissipation plates 4 are installed on the top of the inner cavity of the lower cavity 13. One end of each heat dissipation plate 4 is inserted through the upper cavity 12, and the other end of each heat dissipation plate 4 extends into the water storage tank 3. The bottom of each heat dissipation plate 4 does not contact the bottom of the inner cavity of the water storage tank 3. Each heat dissipation plate 4 is made of copper and has multiple through holes 41. When the camera body 2 is working, the heat generated by the camera body 2 during operation can be discharged from the upper cavity 12 through the heat dissipation plates 4. The heat dissipation plates 4 are placed in the cleaning water in the water storage tank 3, so that the cleaning water in the water storage tank 3 can cool the heat dissipation plates 4. At the same time, the through holes 41 increase the heat dissipation area of ​​the heat dissipation plates 4, further improving the heat dissipation effect of the camera body 2 during operation.

[0030] It is worth noting that, see Figure 2 and Figure 4 The cleaning rod 74 has multiple water inlet holes on its lower housing 1, all of which are connected to the lower cavity 13. A baffle 11 is installed on the inner wall of the housing 1 on one side of the water inlet holes. A filter element 61 is provided on one side of the inner cavity of the lower cavity 13, and the bottom of the filter element 61 slides through the housing 1 and is placed at the bottom of the housing 1. A connecting plate 6 is installed at the bottom of the filter element 61, and a first fixing bolt 62 passes through the connecting plate 6. The first fixing bolt 62 is threadedly connected to the bottom surface of the housing 1. When the water spray hole When the water sprayed from 76 cleans the lens of the camera body 2, the wastewater generated during cleaning flows back into the water storage tank 3 through the water inlet and the lower cavity 13. Before the wastewater is recycled into the water storage tank 3, it is filtered by the filter element 61 to ensure the cleanliness of the wastewater and prevent the water spray hole 76 from becoming clogged when the wastewater is recycled and reused. In addition, when the wastewater is recycled, the baffle frame 11 blocks the wastewater to ensure that the wastewater flows into the water inlet. Moreover, the filter screen can be easily disassembled and installed by turning the first fixing bolt 62, which facilitates the cleaning or replacement of the filter screen.

[0031] It is worth noting that, see Figure 1 The water storage tank 3 is equipped with a transparent observation window 32 at its front end. A water injection hole is provided on one side of the water storage tank 3 near the transparent observation window 32, and a sealing plug 31 is provided in the water injection hole. The capacity of the cleaning water in the water storage tank 3 can be easily observed from the outside through the transparent observation window 32. When the capacity of the cleaning water in the water storage tank 3 is insufficient, the sealing plug 31 is removed from the water injection hole, and then cleaning water is added to the water storage tank 3 through the water injection hole.

[0032] It is worth mentioning that, see Figure 1 The bottom of the water storage tank 3 is equipped with an installation plate 8, and a second fixing bolt 81 passes through the installation plate 8 to facilitate fixing the shell 1 in the use position.
