[0027] like Figure 1-5 As shown, this utility model provides a drainage pipeline detection device.

[0028] Reference Figure 1 As shown, a drainage pipeline detection device includes a body 1, a detection head 2 installed at one end of the body 1, a camera 4 and several searchlights 3 installed inside the detection head 2, several wheels 5 installed on both sides of the body 1, a connector 6 installed on the side of the body 1 away from the detection head 2, a connecting line 7 installed on the side of the connector 6 away from the body 1, a protective structure 8 provided on the side of the body 1 close to the connector 6, and an auxiliary structure 9 provided on the upper surface of the body 1.

[0029] The specific design and function of its protective structure 8 and auxiliary structure 9 will be explained below.

[0030] Reference Figures 2 to 4 As shown in this embodiment: the protective structure 8 includes several limiting blocks 801, which are fixedly connected to the body 1. A rotating shaft 809 is rotatably connected between the inner walls of two limiting blocks 801. A connecting rod 802 is fixedly connected to the arc surface of the rotating shaft 809. A connecting plate 804 is fixedly connected to the side of the connecting rods 802 that are close to each other. A clamping plate 807 is fixedly connected to the end of the connecting plates 804 that are close to each other. An elastic ring 806 is fitted on the side of the connecting rods 802 that are far from each other. Several pads 803 are fixedly connected to the arc surface of the connecting line 7. The clamping plate 807 abuts against the pads 803. A coil spring 810 is fitted on the arc surface of both ends of the rotating shaft 809. The two ends of the coil spring 810 are fixedly connected to the limiting block 801 and the connecting rod 802, respectively.

[0031] When it is necessary to add a safety barrier between the machine body 1 and the connector 6 and connecting wire 7, pull the connecting rod 802 to rotate it. The connecting rod 802 drives the rotating shaft 809 to rotate, and the rotating shaft 809 drives the coil spring 810 to retract. Then, the connecting rod 802 drives the connecting plate 804 and the clamping plate 807 to move. Then, the connecting wire 7 passes through several clamping plates 807 and connects to the connector 6 on the machine body 1. After the connector 6 and connecting wire 7 are connected to the machine body 1, release the connecting rod 802 and the coil spring 810. The tensioning action causes the connecting rod 802 to reset. Then, the connecting rod 802 drives the connecting plate 804 and clamping plate 807 to wrap around the connecting wire 7, securing the elastic ring 806 onto the connecting rod 802. The clamping plate 807 then abuts against the pad 803. If the machine body 1 detaches from the connector 6 and connecting wire 7, the clamping plate 807 and pad 803 act as a safety device to prevent the machine body 1 from being lost. A stop plate 805 is fixedly connected to the end of the connecting rod 802 furthest from the machine body 1. The stop plate 805 has a rectangular cross-section. The stop plate 805 prevents the elastic ring 806 from slipping, thus preventing it from loosening when securing the connecting rod 802. Protective pads 808, which are rubber pads, are fixedly connected to the adjacent sides of the clamping plates 807. The protective pad 808 protects the connecting wire 7, preventing wear and tear on the connecting wire 7 when the clamp 807 is used for protection. The connecting rod 802 has a rectangular cross-section and is made of stainless steel. The stainless steel material increases the service life of the connecting rod 802 and prevents it from rusting during use.

[0032] Reference Figure 5 As shown in this embodiment: the auxiliary structure 9 includes an auxiliary groove 96, which is formed on the body 1. A rotating rod 91 is rotatably connected to the inner wall of the auxiliary groove 96. Two fixing rings 93 are fixedly connected to the arc surface of the rotating rod 91, and a handle 94 is fixedly connected to the arc surface of the fixing rings 93. When it is necessary to lift the body 1, the handle 94 is pulled to move it. The handle 94 drives the fixing rings 93 to move, and the fixing rings 93 drive the rotating rod 91 to move. The rotating rod 91 rotates on the inner wall of the auxiliary groove 96, and then the rotating rod 91 drives the body 1 to move, thereby making it easier to lift the body 1. An anti-slip sleeve 95 is fixedly connected to the arc surface of the handle 94. The anti-slip sleeve 95 has a circular cross-section. The anti-slip sleeve 95 can increase the friction between the hand and the handle 94 and prevent slippage when pulling the handle 94. Torsion springs 92 are sleeved on the arc surfaces at both ends of the rotating rod 91. The two ends of the torsion springs 92 are fixedly connected to the auxiliary groove 96 and the fixing rings 93, respectively. When the handle 94 is pulled, the retaining ring 93 causes the torsion spring 92 to retract. After use, the rebound force of the torsion spring 92 can cause the handle 94 to return to its original position.

[0033] Detailed Instructions for Use: When it is necessary to add a safety barrier between the machine body 1, connector 6, and connecting wire 7, pull the connecting rod 802 to rotate it. The connecting rod 802 drives the rotating shaft 809 to rotate, and the rotating shaft 809 drives the coil spring 810 to retract. Then, the connecting rod 802 drives the connecting plate 804 and clamping plate 807 to move. Then, the connecting wire 7 passes through several clamping plates 807 and connects to the connector 6 on the machine body 1. After the connector 6 and connecting wire 7 are connected to the machine body 1, release the connecting rod 802, and the coil spring 810 will stretch and reset the connecting rod 802. Then, the connecting rod 802 drives the connecting plate 804 and clamping plate 807 to... The elastic ring 806 is placed on the connecting rod 802 and fixed in place. Then, the clamping plate 807 and the pad 803 abut against each other. Once the machine body 1 is separated from the connector 6 and the connecting line 7, the clamping plate 807 and the pad 803 can act as a safety device to prevent the machine body 1 from being lost. The abutting plate 805 can prevent the elastic ring 806 from slipping off, thereby preventing the elastic ring 806 from loosening when fixing the connecting rod 802. The protective pad 808 can protect the connecting line 7 and prevent the clamping plate 807 from causing wear to the connecting line 7 when providing protection. The stainless steel material can increase the service life of the connecting rod 802 and prevent the connecting rod 802 from rusting during use.

[0034] When it is necessary to lift the body 1, pull the handle 94 to move it. The handle 94 drives the fixing ring 93 to move, and the fixing ring 93 drives the rotating rod 91 to move. The rotating rod 91 rotates on the inner wall of the auxiliary groove 96, and then the rotating rod 91 drives the body 1 to move, so that the body 1 can be lifted easily. The anti-slip sleeve 95 can increase the friction between the hand and the handle 94 and prevent slippage when pulling the handle 94. When the handle 94 is pulled for use, the fixing ring 93 drives the torsion spring 92 to retract. After use, the rebound force of the torsion spring 92 can drive the handle 94 to return to its original position.
