Description

Technical Field

[0001] The utility model belongs to an electric power equipment inspection vehicle, in particular to a transformer substation inspection vehicle. Background Art

[0002] Intelligent industrial inspection carts are widely used in inspection and maintenance of substations due to their high safety factor and strong reliability. In the process of using the inspection cart for inspection, the real-time picture inside the substation can be obtained through the camera in real time, and the dust or small debris inside the substation can easily fall on the camera, which can easily cause unclear picture acquisition. The existing document CN212256105 U discloses an intelligent line inspection cart for substations, which cleans the camera by setting a cleaning brush to reciprocate along the surface of the camera. However, due to the friction between the cleaning brush and the camera, during the reciprocating movement of the cleaning brush, there are debris stuck between the cleaning brush and the camera, which is not easy to fall off, resulting in poor cleaning effect. Therefore, it is necessary to propose a substation inspection car to solve the above problems. Utility Model Content

[0005] Furthermore, a first cavity for installing a camera and a second cavity for installing a chain sprocket assembly are provided in the mounting shell, the first cavity is separated from the second cavity, a slide groove communicating with the second cavity is provided on the mounting shell, and the connecting rod is slidably installed in the slide groove.

DETAILED DESCRIPTION

[0019] like Figure 1-4 As shown, a substation inspection vehicle comprises: a mobile vehicle 1 and a camera 2 installed on the mobile vehicle 1, the walking parts of the mobile vehicle 1 adopt a wheat wheel and a matching driving mechanism, the mobile vehicle 1 is rotatably installed with a rotating table 101, the rotating table 101 is fixedly installed with a mounting shell 102, the camera 2 is fixedly installed in the mounting shell 102, the mounting shell 102 is provided with a plane light transmitting mirror 103 for light transmission, the mounting shell 102 is installed with a chain sprocket assembly 3, the chain 301 in the chain sprocket assembly 3 is fixedly connected with a connecting rod 302, and the connecting rod 302 is installed with a cleaning assembly 4 capable of contacting the plane light transmitting mirror 103 away from the camera 2 side.

[0020] In the present solution, when the chain 301 moves, it can drive the connecting rod 302 to do reciprocating motion, wherein when the connecting rod 302 moves along the first direction, the cleaning component 4 contacts the plane light-transmitting mirror 103 to clean the plane light-transmitting mirror 103; when the connecting rod 302 moves along the second direction, the cleaning component 4 is disengaged from the plane light-transmitting mirror 103, so that the debris clamped by the cleaning component 4 and the plane light-transmitting mirror 103 during the cleaning process falls off, thereby improving the cleaning effect; by providing the plane light-transmitting mirror 103, direct cleaning of the camera head of the camera 2 is avoided, so that different types of cameras 2 can be installed in the mounting shell 102; and by rotating the rotating table 101, 360° shooting without blind spots is achieved.

[0021] In one embodiment of the utility model, a first cavity 104 for installing a camera 2 and a second cavity 105 for installing a chain sprocket assembly 3 are provided in the mounting shell 102. The first cavity 104 and the second cavity 105 are separated from each other. A slide groove 106 connected to the second cavity 105 is provided on the mounting shell 102, and the connecting rod 302 is slidably installed in the slide groove 106.

[0022] In this solution, the chain sprocket assembly 3 is installed in the mounting shell 102 to prevent the chain sprocket assembly 3 from being exposed and to prevent foreign debris from falling on the chain sprocket assembly 3 and causing the chain sprocket assembly 3 to jam. The first cavity 104 and the second cavity 105 are separated to prevent foreign debris from entering the first cavity 104 and blocking the camera 2. The slide groove 106 is provided to enable the connecting rod 302 to extend out of the mounting shell 102 through the slide groove 106, and the slide groove 106 cooperates with the connecting rod 302 to ensure the sliding stability of the connecting rod 302.

[0023] In one embodiment of the present invention, two second cavities 105 are provided, and the two second cavities 105 are symmetrically arranged about the installation axis of the camera 2 , and the cleaning assembly 4 is fixedly installed between the connecting rods 302 extending from the two cavities 105 .

[0024] In this solution, two chain sprocket assemblies 3 are provided to ensure the stability of the movement of the cleaning assembly 4.

[0025] In one embodiment of the utility model, the chain sprocket assembly 3 includes two sprockets 303 rotatably installed in the second cavity 105 through a connecting shaft, and a chain 301 is installed around the two sprockets 303. The two chain sprocket assemblies 3 move synchronously through the transmission assembly 5.

[0026] In this solution, the two chains 301 are driven to move synchronously by the transmission assembly 5 to ensure the stability of the movement of the cleaning assembly 4.

[0027] In one embodiment of the utility model, the transmission assembly 5 includes a first gear 501 installed on the upper connecting shaft of the two chain sprocket assemblies 3 and a second gear 502 meshingly installed on one side of the first gear 501. The center line of the first gear 501 and the second gear 502 is perpendicular to the center line of the two sprockets 303. The first gear 501 is located on the side of the connecting shaft away from the connecting rod 302. The two second gears 502 are connected by a rotating shaft 503 rotatably installed in the mounting shell 102. One end of the rotating shaft 503 is fixedly connected to a driving mechanism for driving the rotating shaft 503 to rotate.

[0028] In this solution, the driving mechanism is a motor. The starting motor drives the rotating shaft 503 and the second gear 502 to rotate, thereby driving the two first gears 501 to rotate synchronously, thereby driving the two chain sprocket assemblies 3 to move synchronously; the synchronous movement of the two chain sprocket assemblies 3 is achieved through a driving mechanism and a transmission assembly 5, which saves costs and ensures the rationality of the structure.

[0029] In one embodiment of the utility model, the cleaning component 4 includes a fixed frame 401 fixedly installed between two connecting rods 302, a limiting slide groove 402 is provided in the fixed frame 401, a cleaning brush 403 is slidingly installed in the limiting slide groove 402, and an elastic member 404 is fixedly connected between the cleaning brush 403 and the inner wall of the limiting slide groove 402.

[0030] In the present embodiment, the elastic member 404 includes but is not limited to a spring and an elastic pad. When the connecting rod 302 drives the cleaning component 4 to clean the plane transparent mirror 103, the cleaning brush 403 is pressed against the plane transparent mirror 103 under the action of the elastic member 404 to improve the cleaning effect. When the cleaning component 4 is separated from the plane transparent mirror 103, due to the elastic force of the elastic member 404, the debris sandwiched between the cleaning brush 403 and the plane transparent mirror 103 during the cleaning process can be shaken off.

[0031] In one embodiment of the present invention, when the cleaning component 4 moves downward, the cleaning brush 403 is in close contact with the plane light-transmitting mirror 103; when the cleaning component 4 moves upward, the cleaning brush 403 is separated from the plane light-transmitting mirror 103.

[0032] In this solution, the cleaning component 4 cleans downwards, which is more conducive to the falling of dust or debris and avoids repeated cleaning.
