Figure 4Schematic diagram of the cross-sectional structure of the sliding hole provided in the embodiment of the present application. The unmanned vehicle 100 for spraying the inner wall of the pipeline includes a driving vehicle 110 and a spraying vehicle 120. In the embodiment of the present application, the load power supply and the driving assembly in the driving vehicle are used to realize the functions of powering the entire device and driving the entire device to move on the inner wall of the pipeline. Paint and the like can be added to the spraying vehicle 120 and evenly sprayed onto the inner wall of the pipeline by the spraying vehicle 120. Thus, the various functional areas in this device are clearly distinguished. The driving vehicle 110 and the spraying vehicle 120 are connected by a universal joint assembly 130. The universal joint assembly 130 can be purchased on the market. The universal joint assembly 130 can ensure a flexible connection between the driving vehicle 110 and the spraying vehicle 120. When the entire device undergoes ups and downs in the pipeline, the universal joint assembly 130 can ensure that the connection between the driving vehicle 110 and the spraying vehicle 120 is not destroyed. The driving vehicle 110 is provided with a battery assembly 111 and a driving assembly. The battery assembly 111 is used to power the driving assembly and other components such as the LED lamp 122a. The battery assembly 111 can be a storage battery. There are many types of lithium batteries, etc., as long as they meet the use requirements, and no excessive restrictions are made here. The battery assembly 111 is electrically connected to the socket 112, and the socket 112 is located on the side of the driving vehicle 110 close to the spray vehicle 120. The socket 112 and the plug assembly 123 match. When the plug assembly 123 is inserted into the socket 112, the circuit between the electrical components in each spray vehicle 120 and the battery assembly 111 will be connected, and the battery assembly 111 can now supply power normally. The spraying vehicle 120 is provided with a spraying component 121 and a camera component 122. The spraying component 121 can be set up with reference to the existing technology. In addition, the camera component 122 is used to shoot the path and spraying status of the device spraying inside the pipe. At the same time, the camera component 122 can output the input information to the display port in a timely manner through the external screen display device. The spraying component 121 and the camera component 122 are electrically connected to a plug component 123. When the plug component 123 is connected to the socket 112, the spraying component 121 and the camera component 122 are powered. Cards 131 are respectively connected to both ends of the universal joint assembly 130. The cards 131 at both ends are used to be inserted into the driving vehicle 110 and the spraying vehicle 120 respectively, so as to realize the connection of the driving vehicle 110 and the spraying vehicle 120 into one through the universal joint assembly 130. A T-shaped slot 124 for receiving a card 131 is respectively provided on one side of the driving vehicle 110 and the spraying vehicle 120 , and the card 131 can be inserted from the top to the bottom of the T-shaped slot 124 .A sliding hole 125 is provided on one side of the T-slot 124. A rod 127 is connected to the sliding hole 125 through a spring assembly 126. The end of the rod 127 extends to the outside of the sliding hole 125 and is connected to a hook 127a. A positioning hole 131a matching the hook 127a is provided on the card 131. When the card 131 is inserted into the bottom of the T-slot 124, the hook 127a is dragged and the spring assembly 126 is stretched, so that the hook 127a and After the rod 127 moves as a whole to the outside of the sliding hole 125, the hook head 127a is inserted into the positioning hole 131a on the card 131. Under the action of the elastic member, the rod 127 retracts into the sliding hole 125. At this time, the card 131 will be fixed inside the T-slot 124. When the cards 131 at both ends are respectively connected to the driving vehicle 110 and the spraying vehicle 120, the driving vehicle 110 and the spraying vehicle 120 will be connected as a whole through the universal joint assembly 130.

[0023] As can be seen from the above, in the embodiment of the present application, by providing a driving cart 110 and a spraying cart 120, and respectively placing the driving assembly and the spraying assembly in the driving cart 110 and the spraying cart 120, the functional areas are cleanly separated, which not only facilitates subsequent maintenance but also effectively prevents interference between the functional areas. By providing components such as the T-slot 124, the card 131, the hook 127a, and the elastic member, when the driving device fails or the power supply is insufficient, it is only necessary to remove the card 131 connected to the driving cart 110 and replace it with a new driving cart 110 for normal use. The removed driving cart 110 can then be repaired. During the disassembly process, the hook head 127a is pulled out of the positioning hole 131a and rotated so that the hook head 127a is retracted into the sliding hole 125 under the action of the elastic member. At this time, the card 131 is no longer blocked by the hook head 127a, and the card 131 can be quickly withdrawn along the T-slot 124. The plug is then pulled out of the socket 112, and the universal joint assembly 130 is now connected to the driving vehicle 110. The entire process is quick and convenient, allowing the disabled vehicle to be put into use quickly.

[0024] In some embodiments, the drive assembly includes a drive wheel 140 and a driven wheel 150 sequentially disposed at the bottom of the drive vehicle 110. The battery assembly 111 is electrically connected to a drive motor, which is electrically connected to the drive wheel 140. At least two sets of driven wheels 150 are disposed at the bottom of the spraying vehicle 120. In this embodiment of the present application, power is supplied to the drive motor via the battery assembly 111. When the drive motor is turned on, it further drives the drive wheel 140 to rotate, thereby driving the drive vehicle 110 and the spraying vehicle 120 as a whole to move along the inner diameter of the pipeline to be sprayed, thereby completing the full-scale spraying of the interior of the pipeline to be sprayed.

[0025] In some embodiments, the spray assembly 121 includes a paint tank 121a disposed in the spray vehicle 120, a spray motor 121b disposed at one end of the spray vehicle 120 away from the drive vehicle 110, and a sprayer 121c connected to the spray motor 121b. The paint tank 121a is connected to the spray motor 121b via a pipe. In the embodiment of the present application, a specific arrangement of the spray assembly 121 is shown. During operation, when the spray motor 121b is started, the paint in the paint tank 121a will be transported to the spray motor 121b through the pipe, and further transported to the sprayer 121c by the spray motor 121b, and finally sprayed by the sprayer 121c onto the inner wall of the pipe to be sprayed.

[0026] In some embodiments, a mist shield 121d is provided on the side of the sprayer 121c near the spraying vehicle 120. The mist shield 121d is provided on the periphery of the spraying motor 121b and is located between the camera assembly 122 and the sprayer 121c. In this embodiment of the present application, by providing the mist shield 121d, the paint mist sprayed by the sprayer 121c will be blocked by the mist shield 121d as the sprayer 121c moves forward with the entire device, thereby preventing the paint from contaminating the camera assembly 122 and causing problems such as unclear imaging or damage to the camera assembly 122.

[0027] In some embodiments, the camera assembly 122 includes a camera 122b and an LED light 122a disposed at one end of the spraying vehicle 120, and both the camera 122b and the LED light 122a are electrically connected to the plug assembly 123. In the present application, the LED light 122a is provided to illuminate the interior of the pipe, so that the device can still meet the camera conditions even when the pipe to be sprayed is long and the light inside the pipe is dim.

[0028] In some embodiments, the sliding hole 125 extends to one end of the outer wall of the driving vehicle 110 or the spraying vehicle 120 and expands outward to form a receiving groove 125a that matches the hook head 127a. In this embodiment of the present application, the provision of the receiving groove 125a can accommodate the hook head 127a. After the hook head 127a is separated from the card 131, the elastic member can pull the hook head 127a into the receiving groove 125a, thereby preventing damage such as bending caused by collision.
