The outer ends of the compression springs are fixedly connected to the inner walls of the tops of the connecting rods. Fixed disks are fixedly connected to the outer ends of both connecting rods. Crushing teeth are fixedly connected to the outer ends of both fixed disks. The device is lifted into the pipeline opening by a vehicle cable with a hook. When the device moves in the pipeline, it is monitored in real time through a camera. When scale and crushed mud are seen on both sides of the pipeline, the controller is used to control the double-headed motor to drive the fixed rod to rotate. The fixed rod drives the connecting rod to rotate. The connecting rod drives the fixed disk to rotate. The fixed disk drives the crushing teeth to rotate, so as to remove the crushed mud in the pipeline.

[0005] However, because the double-headed motor is fixed on the bottom plate, the position of the double-headed motor cannot rotate. Therefore, in actual use, the fixed disk installed on the double-headed motor can only slide along one horizontal direction of the inner wall of the pipeline, that is, the crushing teeth on the fixed disk cannot cover the entire inner wall of the pipeline.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] As Figures 1-5 shown, a portable municipal pipeline detection device includes a moving base plate 1 known to be equipped with a camera and mud-breaking teeth. Active gears 6 are installed on both sides of the moving base plate 1, and a driven gear 5 meshing with the active gear 6 is rotatably connected to the side of the moving base plate 1. A limiting frame 18 is fixedly connected to the end face of the driven gear 5. A rack 3 is inserted into the inner wall of the limiting frame 18, and a spur gear 7 meshing with the rack 3 is rotatably connected through the outer wall of one side. Two rollers 2 are symmetrically and rotatably connected to the end face of one of the spur gears 7. The camera on the moving base plate 1 is installed at a position between the two rollers 2 on one of the racks 3, and the mud-breaking teeth are installed on the end face of the other rack 3. One end of the active gear 6 is fixedly connected to a transmission shaft 13 rotatably connected through the side of the moving base plate 1, and a driving mechanism for driving the transmission shaft 13 to rotate is provided on the moving base plate 1;

[0026] As Figure 1 shown, when the driving mechanism is used to drive the left transmission shaft 13 to rotate, the left active gear 6 can be rotated, and then the engaged driven gear 5 can be rotated. The limiting frame 18 driven by the rotation of the driven gear 5 drives the rack 3 to rotate, so that the roller 2 installed at the end of the left rack 3 can roll along the inner wall of the pipeline. When rolling, since the moving base plate 1 is arranged at the bottom inside the pipeline and not at the center line of the pipeline, the distances between the moving base plate 1 and different positions of the inner wall of the pipeline are different. Therefore, in this solution, the spur gear 7 can be rotated by means of motor drive, and then the rack 3 engaged with it can slide relative to the limiting frame 18, so as to adjust the distance between the roller 2 and the inner wall of the pipeline. That is, when the driven gear 5 drives the rack 3 to rotate, the rack 3 can slide to ensure that the camera installed in the roller 2 maintains a reasonable distance from the inner wall of the pipeline, that is, to ensure clear shooting:

[0027] Similarly, when the driving mechanism drives the right transmission shaft 13 to rotate, the right driving gear 6 can be rotated, and then the meshing-connected driven gear 5 can be rotated. By using the rotation of the driven gear 5 to drive the limiting frame 18 to drive the rack 3 to rotate, the mud-breaking tooth roller 2 installed at the end of the left rack 3 can be moved along the inner wall of the pipeline. When moving, the spur gear 7 is rotated by means of electric motor drive, and then the meshing-connected rack 3 is slid relative to the limiting frame 18, so as to adjust the distance between the mud-breaking teeth and the inner wall of the pipeline, that is, to ensure that the mud-breaking teeth can perform mud-breaking treatment on the inner wall of the pipeline for one week. And when mud-breaking, by applying a thrust to the right rack 3, a downward pressing force can be realized when the mud-breaking teeth are mud-breaking, which is convenient for processing harder objects. In addition, the mud-breaking teeth of this solution are also driven by installing an electric motor at the end of the right rack 3.

[0028] In addition, in order to prevent the angle deviation of the rack 3 in the inclined state: two symmetrically arranged electric telescopic rods 4 are fixedly connected to the inner embedding of the upper surface of the moving bottom plate 1. The telescopic ends of the two electric telescopic rods 4 respectively face the two transmission shafts 13, and the telescopic ends of the electric telescopic rods 4 are fixedly connected with brake pads 17. When the electric telescopic rod 4 extends, the brake pad 17 tightly fits the end bevel gear 15 at the end face of the corresponding transmission shaft 13. Under the action of friction, the rotation of the end bevel gear 15 is prevented, and then the position and angle of the transmission shaft 13 and the driving gear 6 connected to the transmission shaft 13 are fixed.

[0029] The movement and traveling mode of the moving bottom plate 1 in this solution refer to the movement and use mode of the bottom plate in a portable municipal pipeline remote control detection device with the publication number of CN218883374U.

[0030] Further: The driving mechanism includes an end bevel gear 15 fixedly connected to the end face of the transmission shaft 13. The driving mechanism also includes two sliding frames 10 inserted into the upper surface of the moving bottom plate 1, and a driving bevel gear 19 rotatably connected to the moving bottom plate 1 and meshing with the end bevel gear 15. A transmission sprocket 14 is fixedly connected to the end face of the driving bevel gear 19.

[0031] A stretching sprocket 9 is rotatably connected in the sliding frame 10. A chain 16 is meshed between the two stretching sprockets 9. A support frame 8 sleeved on the chain 16 and fixedly connected to the upper surface of the moving bottom plate 1 between the stretching sprockets 9 is slidably connected between the two stretching sprockets 9. And a sliding frame 12 for driving the chain 16 to mesh with the transmission sprocket 14. An electric telescopic rod 4 for driving the sliding frame 12 to slide is also fixedly connected to the moving bottom plate 1;

[0032] Such as Figure 2 and Figure 4As shown in the figure, when the electric telescopic rod 4 extends until the sliding frame 12 moves to the right transmission sprocket 14, the lateral depth of the set sliding frame 12 is greater than the radius of the transmission sprocket 14, and the longitudinal length of the sliding frame 12 itself is greater than the diameter of the transmission sprocket 14. Therefore, the sliding frame 12 can be sleeved on the transmission sprocket 14, thereby ensuring that there is enough wrap angle between the chain 16 and the transmission sprocket 14. Therefore, by installing a motor to drive one of the tension sprockets 9 to rotate, the movement of the chain 16 in a taut state can be realized. Under the meshing connection, the transmission sprocket 14 on the right drives the driving bevel gear 19 to rotate, and then the end bevel gear 15 in meshing connection drives the transmission shaft 13 on the right to rotate. Conversely, when the electric telescopic rod 4 contracts until the sliding frame 12 is sleeved with the transmission sprocket 14 on the left and a part of the chain 16 is meshed with the transmission sprocket 14 on the left, the transmission sprocket 14 on the left can rotate as the tension sprocket 9 rotates.

[0033] In order to ensure that the chain 16 is always in a straightened state: two sliding frames 10 are respectively arranged on two adjacent sides of the driving gear 6, and a spring rod 11 is fixedly connected between the sliding frame 10 and the side of the moving bottom plate 1. When the chain 16 is meshed with the transmission sprocket 14 on the left or right, the set spring rod 11 is in a fully extended state. Therefore, when the sliding frame 12 slides between the two transmission sprockets 14, the elastic contraction of the spring rod 11 is used to pull the sliding frames 12 away from each other, so that the chain 16 can be straightened and tightened. And with the auxiliary effect of the support frame 8, the chain 16 is further prevented from bending downwards.

[0034] Working principle: Place the moving bottom plate 1 in the pipeline, and then use the driving mechanism to drive the transmission shaft 13 on the left to rotate, so that the driving gear 6 on the left drives the driven gear 5 to rotate, and the roller 2 installed at the end of the rack 3 on the left rolls along the inner wall of the pipeline. When rolling, the rack 3 slides relative to the limit frame 18, so that the distance between the roller 2 and the inner wall of the pipeline can be adjusted. By using the sliding of the rack 3, the camera installed in the roller 2 can be ensured to take pictures of the inner wall of the pipeline for one week. Then, after the moving bottom plate 1 moves to the position where the mud-breaking teeth reach the camera, the mud-breaking teeth rotate, and the driving mechanism is used to drive the transmission shaft 13 on the right to rotate to realize the rotation of the driving gear 6 on the right. Then, the rotation of the driven gear 5 in meshing connection drives the limit frame 18 to drive the rack 3 to rotate, so that the mud-breaking tooth roller 2 installed at the end of the rack 3 on the left can move along the inner wall of the pipeline and clean the inner wall of the pipeline.

[0035] The wiring diagrams of the electric telescopic rod 4 and the motor in the present utility model belong to the common knowledge in the art, and their working principles are already well-known technologies. Their models are selected according to actual use, so the control methods and wiring arrangements of the electric telescopic rod 4 and the motor will not be explained in detail.

[0036] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
