Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline desilting equipment, and in particular relates to a pipeline inspection and desilting device. Background Art

[0002] The construction of municipal drainage facilities is an important part of urban infrastructure construction.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] Reference Figure 1-Figure 5 The present invention provides a pipeline inspection and desilting device, comprising:

[0032] Body 1;

[0033] The dredging assembly includes a working box 14 disposed at the head of the vehicle body 1. A push plate 15 is disposed on the side of the working box 14 away from the vehicle body 1. Two sets of air inlets 37 for sucking sludge are opened on the side of the push plate 15 away from the vehicle body 1. The two air inlets 37 are respectively provided with a filter screen 21. A switching assembly is provided in the working box 14. The switching assembly is used to alternately generate negative pressure in the two sets of air inlets 37 so that the two sets of air inlets 37 work alternately. A solid debris collection assembly is provided at the bottom of the push plate 15. A storage box 4 connected to the solid debris collection assembly is provided in the vehicle body 1;

[0034] The troubleshooting component includes a detection control box 6 arranged on the vehicle body 1, and the detection control box 6 is electrically connected to the pipe wall damage detection component and the harmful gas detection component.

[0035] The main function of the vehicle body 1 is to facilitate the movement of the dredging device in the pipeline; the main function of the push plate 15 is to integrate the air inlet 37 and the solid debris collection component, and at the same time shovel up the silt accumulated at the bottom of the pipeline; the main function of the switching component is to make the two groups of air inlets 37 work alternately. During the process of one group of air inlets 37 sucking silt, the debris on the filter screen 21 in the other group of air inlets 37 can fall back into the water, avoiding the influence of debris accumulation on silt suction; the main function of the solid debris collection component is to collect solid debris in the water and transport it to the storage box 4 to realize the cleaning of solid debris; the main function of the detection control box 6 is to receive the detection data of the pipe wall damage detection component and the detection data of the harmful gas detection component, and send the data to the ground control terminal. On the whole, the present invention integrates the air inlet and the solid debris collection component on the push plate, so that the sludge and solid debris are collected separately, reducing the impact of solid debris on sludge suction; at the same time, two groups of air inlets are opened, and the two air inlets are alternately operated by switching components. During the process of sucking sludge through one air inlet, solid impurities on the filter screen in the other group of air inlets can be washed off the filter screen, which can effectively avoid the impact of solid debris on the sludge suction work; in addition, the present invention arranges pipe wall damage detection components and harmful gas detection components on the vehicle body, so that the inside of the pipeline can be inspected and checked while dredging the pipeline.

[0036] To further optimize the solution, a walking track 10 is provided at the bottom of the vehicle body 1 so that the vehicle body 1 can move smoothly in the pipeline.

[0037] To further optimize the solution, a working hole 11 is provided at the front end of the vehicle body 1, one end of a support arm 13 is hinged in the working hole 11, the other end of the support arm 13 is fixedly connected to the working box 14, and a telescopic rod 12 is hinged between the top of the working hole 11 and the support arm 13.

[0038] like Figure 1 As shown, an electric telescopic rod can be selected for use with the telescopic rod 12. During the desilting process, the height of the push plate 15 can be adjusted by controlling the length of the telescopic rod 12 so that the bottom of the push plate 15 is close to the inner wall bottom of the pipeline, thereby making the desilting effect more thorough.

[0039] A further optimized solution is that the switching component includes a control shell 25 fixedly connected to the working box 14, and an air duct 27 is opened in the control shell 25. The two ends of the air duct 27 are respectively connected to two air inlets 37, and the middle part of the air duct 27 is connected to the air outlet 26, and the air outlet 26 is connected to the negative pressure generating part. A piston plate 28 is slidably connected in the air duct 27, and a movable control part is provided between the piston plate 28 and the control shell 25. The piston plate 28 is close to an air inlet 37 and seals the air inlet 37.

[0040] like Figure 3 and Figure 5As shown, when the piston plate 28 moves to the left side, the piston plate 28 blocks the air vent at the left end of the air duct 27, so that negative pressure no longer occurs at the air inlet 37 on the left side. At the same time, the air inlet 37 on the right side is connected to the air outlet 26 through the air vent at the right end of the air duct 27. The air inlet 37 on the right side generates negative pressure under the action of the negative pressure generating element, thereby realizing the suction of sludge.

[0041] Similarly, when the piston plate 28 moves to the right, the left air inlet 37 performs sludge suction work.

[0042] To further optimize the solution, when dredging in a pipeline with little solid debris, in order to improve work efficiency, the piston plate 28 can be moved to the middle of the air duct 27. At this time, the air outlet 26 is connected to the two air inlets 37, so that the two air inlets 37 can suck the silt at the same time.

[0043] To further optimize the solution, the movable control part includes a slide groove 32 opened on the side wall of the air duct 27 along the axis of the air duct 27, the piston plate 28 is slidingly connected in the slide groove 32 through the movable block 29, and a screw rod 30 is rotatably connected in the control housing 25, one end of the screw rod 30 is transmission-connected to the second motor 31, and the movable block 29 is threadedly sleeved on the screw rod 30.

[0044] like Figure 5 As shown, when the piston plate 28 needs to be moved to the left, the second motor 31 can be controlled to drive the screw 30 to rotate. When the screw 30 rotates, the moving block 29 is driven to the right through the thread transmission, thereby achieving rightward movement of the piston plate 28. At the same time, when the second motor 31 is controlled to rotate in the opposite direction, the piston plate 28 can be moved to the left.

[0045] According to a further optimized solution, the negative pressure generating element includes a negative pressure pump 3 arranged in the vehicle body 1 , and the air inlet of the negative pressure pump 3 is connected to the air outlet 26 .

[0046] like Figure 1 As shown, the air inlet end of the negative pressure pump 3 is connected to the air outlet 26 through a hose.

[0047] To further optimize the solution, the air outlet of the negative pressure pump 3 is connected to the bottom equipment through a hose to directly transport the silt to the ground.

[0048] A further optimized solution is that the solid debris collection assembly includes a conveying roller 17 that is horizontally rotatably connected to the push plate 15. The conveying roller 17 is arranged at the bottom of the push plate 15 away from the vehicle body 1. A first motor 23 is transmission-connected between the conveying roller 17 and the push plate 15. A solid debris inlet 24 is provided at the bottom of the side wall of the push plate 15. The conveying roller 17 is used to convey solid debris to the solid debris inlet 24. A conveying member connected to the solid debris inlet 24 is provided in the working box 14, and the conveying member is also connected to the storage box 4.

[0049] like Figure 2 As shown, two sets of baffles 22 are fixedly connected to the bottom of the side wall of the push plate 15. The two sets of baffles 22 are arranged away from the vehicle body 1, and the conveyor roller 17 is rotatably connected between the two baffles 22. The first motor 23 is fixedly connected to one of the baffles 22. The conveyor roller 17 is provided with spiral blades rotating in opposite directions at both ends. As the conveyor roller 17 is driven by the first motor 23 to rotate, solid debris can be moved along the push plate 15 toward the solid debris inlet 24 in the center under the action of the spiral blades and enter the solid debris inlet 24. The solid debris is then transported by the conveying member to the storage box 4 for temporary storage.

[0050] A further optimized solution is that the conveying member includes a conveying channel 19 opened in the working box 14, one end of the conveying channel 19 is connected to the solid debris inlet 24, and the other end of the conveying channel 19 is connected to the storage box 4. Two sets of conveying belts 20 are arranged in parallel on the inside of the conveying channel 19. The two conveying belts 20 are arranged close to the side wall of the conveying channel 19, and the solid debris is transported to the storage box 4 through the gap between the two conveying belts 20.

[0051] As a further optimization solution, a driving motor is provided between the conveying belt 20 and the working box 14 so that the mutually approaching ends of the two conveying belts 20 move in a direction away from the push plate 15 .

[0052] like Figure 1 As shown, the discharge end of conveying channel 19 is connected to storage box 4 via a hose. After conveying roller 17 conveys solid debris into solid debris inlet 24, the solid debris contacts two conveyor belts 20 and, driven by conveyor belts 20, moves from the center of the two sets of conveyor belts 20 toward storage box 4, thereby collecting the solid debris.

[0053] A further optimized solution is that the distal ends of the two filters 21 are respectively hinged on the inner wall of the air inlet 37, and the proximal ends of the two filters 21 are respectively fixedly connected to one end of a hinged plate 35, the other ends of the two hinged plates 35 are hinged, and the two hinged plates 35 are slidably connected in the push plate 15, and a vibration excitation member is provided between the hinged plate 35 and the push plate 15.

[0054] A further optimized solution is that the vibration excitation member includes a push rod 38 slidingly connected to the push plate 15, one end of the push rod 38 abuts against the hinge of the two hinged plates 35, a cam 34 is rotatably connected inside the push plate 15, the cam 34 abuts against the other end of the push rod 38, and a third motor 33 is transmission-connected to the cam 34, and a spring 36 abuts between the side of the hinged plate 35 away from the push rod 38 and the push plate 15.

[0055] like Figure 3 and Figure 4As shown, when the piston plate 28 moves to the left, sludge is sucked out of the right air inlet 37, while negative pressure is not generated at the left air inlet 37. At this point, the third motor 33 is controlled to rotate, driving the cam 34. This, in turn, pushes the push rod 38. As the push rod 38 moves, it simultaneously pushes the two sets of hinged plates 35. The movement of the hinged plates 35 causes the filter 21 to move and compresses the spring 36. As the cam 34 continues to rotate, the smaller end of the cam contacts the push rod 38. The push rod 38, driven by the spring 36, moves in the opposite direction while maintaining contact with the cam 34. During the rapid rotation of the third motor 33, the push rod 38 and the spring 36 cause the hinged plates 35 to move rapidly back and forth, vibrating the filter 21 and dislodging solid debris from the filter 21, thus clearing the outer teeth of the filter 21. When the left air inlet 37 begins sucking out sludge, no solid debris adheres to the surface of the filter 21.

[0056] To further optimize the solution, the top and bottom of the push plate 15 are respectively fixedly connected with a number of top nozzles 16 and a number of bottom nozzles 18. The top nozzles 16 are used to spray water onto the top wall of the pipe, and the bottom nozzles 18 are used to spray water onto the sludge at the bottom of the pipe. The top nozzles 16 and the bottom nozzles 18 are respectively connected to water supply components.

[0057] To further optimize the solution, the water supply assembly includes a water pump 2 and a water tank 5 arranged in the vehicle body 1, the water inlet end of the water pump 2 is connected to the water tank 5, and a plurality of top nozzles 16 and bottom nozzles 18 are respectively connected to the water outlet end of the water pump 2.

[0058] like Figure 1 As shown, the water pump 2 causes the water in the water tank 5 to be sprayed out from the top nozzle 16 and the bottom nozzle 18. The water in the top nozzle 16 directly flushes the upper part of the inner wall of the pipe, which can flush down the silt, debris, etc. The bottom nozzle 18 can flush up the silt, debris, etc. accumulated at the bottom of the pipe, which is convenient for collecting the silt and solid debris and ensuring the dredging effect.

[0059] Example 2:

[0060] According to a further optimized solution, the pipe wall damage detection component includes a metal flaw detector 7, and the harmful gas detection component includes a methane monitor 8. The metal flaw detector 7 and the methane monitor 8 are respectively fixedly connected to the detection control box 6.

[0061] like Figure 1 As shown, the detection control box 6 is provided with a processor (not shown in the figure) for receiving detection data from the metal flaw detector 7 and the methane monitor 8, and a communicator (not shown in the figure) for transmitting the detection data to the ground mid-terminal equipment, so that the ground staff can understand the internal situation of the pipeline at any time and realize the purpose of investigation and inspection.

[0062] To further optimize the solution, a camera 9 is also provided on the top of the detection control box 6, which can directly capture the internal image of the pipeline.

[0063] like Figure 1 As shown, in this embodiment, the metal flaw detector 7, the methane monitor 8 and the camera 9 are arranged at the rear of the vehicle body 1, which can avoid the interference of dredging work on the detection work. At the same time, the rear of the vehicle body 1 is in a cleaned state, which can avoid the influence of silt and debris, and facilitate effective detection of the pipeline.
