DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] In order to solve the technical problem that when the pipeline is seriously clogged, it is difficult for pipeline dredging equipment to clean the clogged materials in the pipeline. The present invention provides a pipeline dredging equipment, which can first break up the large clogged materials in the pipeline to reduce the volume of the clogged materials. The clogged materials with reduced volume are easier to be collected by the pipeline dredging equipment.

[0018] See also Figure 1-Figure 10 , Figure 1-Figure 10 A pipeline desilting device in an embodiment of the present invention comprises a vehicle body 1, a desilting and blocking mechanism 2 and a twisting and suction mechanism 3, wherein the vehicle body 1 can move in a pipeline; the twisting and suction mechanism 3 comprises a twisting and suction member 31 and a silt storage box 32, wherein the twisting and suction member 31 is connected to the vehicle body 1 and communicates with the silt storage box 32 fixedly arranged on the vehicle body 1, and the twisting and suction member 31 has multiple degrees of freedom of movement; the desilting and blocking mechanism 2 is connected to the vehicle body 1, wherein the desilting and blocking mechanism 2 comprises an adjusting member 21 and a crushing member 22, wherein the adjusting member 21 is connected to the vehicle body 1, and the crushing member 22 is connected to the adjusting member 21, wherein the adjusting member 21 is used to drive the crushing member 22 to move so that the crushing member 22 can be moved out of the vehicle body to crush the silt in the pipeline, and the crushing member 22 can also be moved into the vehicle body 1 to avoid the twisting and suction member 31, and the twisting and suction member 31 can suck the crushed silt into the silt storage box.

[0019] In actual use, the vehicle body 1 can move in the pipeline. When encountering a seriously blocked pipe section, the adjusting member 21 is used to drive the crushing member 22 to move so that the crushing member 22 can be moved out of the vehicle body 1. The crushing member 22 crushes the large blockages. After the large blockages are broken, the number of mud blocks increases, the total contact area increases, and the adhesion between the mud blocks weakens. The adjusting member 21 is used to drive the crushing member 22 to move so that the crushing member 22 can be moved into the vehicle body 1 and avoid the suction member 31. The suction member 31 can suck the crushed blockages into the silt storage tank 32.

[0020] It should be noted that the vehicle body 1 is not limited to a specific structure, as long as it can move in the pipeline, and no other limitation is made here.

[0021] In one embodiment, the vehicle body 1 includes three groups of movable rollers 11, and the three groups of movable rollers 11 are arranged at intervals along the circumference of the vehicle body 1. The movable rollers 11 include forward and reverse screw rods 111, two sliders 112, two support rods 113, two transmission rods 114 and two wheel bodies 115. The forward and reverse screw rods 111 are rotatably arranged in the vehicle body 1, and the two sliders 112 are slidably arranged in the vehicle body 1 and are respectively threadedly connected to the two threaded parts of the forward and reverse screw rods 111.

One ends of the two transmission rods 114 are respectively hinged to the two sliders 112, and the other ends of the two transmission rods 114 are respectively hinged to the middle parts of the two support rods 113.

[0022] In addition, a ratchet 1151 is fixedly provided on the central rotating shaft of the wheel body 115, and a pawl 1131 is hinged on the support rod 113. A spring 1132 is connected between the middle part of the pawl and the support rod 113, and one end of the pawl is engaged with the ratchet. By arranging the ratchet and the pawl to cooperate with each other, it is possible to prevent the wheel body 115 from rotating in the opposite direction and the vehicle body 1 from reversing.

[0023] Specifically, by rotating the forward and reverse screw rods 111, the two sliders 112 can be driven to move relative to each other, thereby driving the two wheel bodies 115 to move. When the two sliders 112 are close to each other, the two wheel bodies 115 can be close to the vehicle body; when the two sliders 112 are away from each other, the two wheel bodies 115 can be away from the vehicle body, ensuring that the vehicle body can be suitable for pipes with different inner diameters.

[0024] Among them, the wheel body 115 is a hub motor, which is also called in-wheel motor technology. Its biggest feature is that the power device, transmission device and braking device are integrated into the wheel hub, so as to simplify the mechanical part of the electric vehicle.

[0025] On the basis of the above scheme, in order to facilitate the adjustment of the positions of the six wheels 115, specifically, a gear 116 is provided in the middle of the three forward and reverse screw rods 111, an internal gear ring 12 is provided in the vehicle body 1, and the three gears 116 are all meshed with the internal gear ring 12, and the line connecting the centers of the three driven gears 116 is an equilateral triangle.

[0026] Specifically, by driving the inner gear ring 12 to rotate, the three forward and reverse screw rods 111 are driven to rotate around their own axes, so that the six wheels 115 can be driven to move simultaneously, which makes adjustment more convenient.

[0027] On the basis of the above scheme, in order to ensure that the vehicle body can walk in a curved pipe, in another embodiment, one of the forward and reverse screw rods 111 includes a first screw rod 1111 and a second screw rod 1112, one end of the first screw rod 1111 and the second screw rod 1112 are both rotatably connected to the vehicle body 1, a fourth driving part 13 is fixedly provided on the vehicle body 1, an output end of the fourth driving part 13 is fixedly connected to the other end of the first screw rod 1111, the other output end of the fourth driving part 13 is fixedly connected to the other end of the second screw rod 1112, the other end of the second screw rod 1112 is rotatably connected to a driven gear 116, and the end of the gear 116 A plurality of slots 1161 are arranged at intervals along the circumferential direction, a guide ring 131 is fixedly arranged at the other output end of the fourth driving part 13, a plurality of limit slots are arranged circumferentially of the guide ring 131, a second telescopic member 14 is fixedly arranged on the vehicle body 1, a movable end of the second telescopic member 14 is rotatably connected to a limit sleeve 15, and a plurality of latch teeth are arranged in the limit sleeve 15, the limit sleeve 15 is sleeved with the guide ring 131, and a plurality of latch teeth are respectively latched in each limit slot, the limit sleeve 15 is pushed by the second telescopic member 14 to slide relative to the guide ring 131, so as to drive the plurality of latch teeth to be respectively latched in each of the slots 1161 at the same time, wherein the second telescopic member 14 is an electric cylinder.

[0028] Specifically, when the vehicle body moves in the pipeline, the first screw rod 1111 and the second screw rod 1112 are located at the top. When the vehicle body needs to pass through a bend to turn, the multiple teeth of the limit sleeve are separated from the slot 1161. The first screw rod 1111 and the second screw rod 1112 are driven to rotate by the fourth driving unit 13, so that the two wheel bodies are separated from the inner wall of the pipeline. At the same time, the two wheel bodies 115 of a group of moving rollers 11 at the bottom and the two wheel bodies 115 of another group of moving rollers 11 travel at different speeds, thereby realizing differential steering.

[0029] Among them, when the multiple locking teeth of the limit sleeve 15 are also inserted into the multiple slots 1161, when the fourth driving part 13 drives the guide ring 131 to rotate, it can drive a gear 116 to rotate. The rotation of the gear 116 drives the inner gear ring 12 to rotate at the same time. The rotation of the inner gear ring 12 can drive the other two gears 116 to rotate, and the synchronous adjustment of the six wheels can be realized.
