DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 A pipeline high-pressure dredging machine, comprising a base 1, a water tank 3 is installed on the base 1, the water tank 3 is connected with a high-pressure water pump 4, the output end of the high-pressure water pump 4 is connected with a water delivery pipe 5, the water delivery pipe 5 is connected with a mounting cylinder 6, one end of the mounting cylinder 6 is connected with a water guide pipe 9, a connecting cylinder 61 is fixedly installed on one side of the mounting cylinder 6, a spiral thread is arranged on the outer surface of the connecting cylinder 61, a limiting groove 611 is arranged on the outer side of the connecting cylinder 61, a fixing piece 7 is arranged on the outer surface of the connecting cylinder 61, a connecting groove 71 is formed in the fixing piece 7, the connecting cylinder 61 is screw-connected with the connecting groove 71, a moving groove 73 is installed on the fixing piece 7, a pull handle 74 is slidably installed in the moving groove 73, the bottom end of the pull handle 74 is fixedly connected with a limiting block 75 through a moving plate 76, the moving plate 76 is connected with the inner wall top end of the moving groove 73 through a spring 77;

[0023] The limiting groove 611 is arranged in parallel along the extension direction of the mounting cylinder 6, the limiting block 75 is connected with the limiting groove 611 through the side wall of the connecting groove 71, and the width of the limiting groove 611 is the same as the width of the limiting block 75;

[0024] A support 2 is fixedly installed on the base 1, a pipe winding cylinder 8 is rotatably installed on the support 2, and the water guide pipe 9 is arranged around the pipe winding cylinder 8;

[0025] The clamping piece 62 is equidistantly fixedly installed on the side of the connecting cylinder 61 away from the mounting cylinder 6, and the extrusion cavity 72 is formed in the fixing piece 7 and corresponds to the clamping piece 62.

[0026] Specifically, the spiral thread on the outer surface of the connecting cylinder 61 is screw-connected with the connecting groove 71 inside the fixing member 7. After the water delivery pipe 5 is inserted into the mounting cylinder 6, the operator controls the screw installation of the fixing member 7 on the connecting cylinder 61. During the screw installation, the connecting cylinder 61 is screw-installed in the connecting groove 71, and at the same time, the clamping piece 62 enters the extrusion cavity 72. The inner wall of the extrusion cavity 72 exerts a certain extrusion force on the clamping piece 62, so that the clamping piece 62 tightly embraces the water delivery pipe 5 from the side, thereby enhancing the tightness and stability of the connection and ensuring that the components are firmly connected and will not easily loosen or disengage.

[0027] To avoid accidental loosening of the fixing member 7 due to vibration, the moving groove 73 is provided on the fixing member 7, and the pull handle 74 is slidingly installed inside the moving groove 73. The bottom end of the pull handle 74 is connected with the limiting block 75 and passes through the moving plate 76. The moving plate 76 is connected with the top end of the inner wall of the moving groove 73 by the spring 77. When the connecting cylinder 61 and the fixing member 7 are screw-connected in place, the spring 77 exerts a downward force on the moving plate 76, which drives the limiting block 75 to pass through the side wall of the connecting groove 71 and insert into the limiting groove 611 outside the connecting cylinder 61. Since the limiting groove 611 is parallelly arranged along the extension direction of the mounting cylinder 6 and has the same width as the limiting block 75, the limiting block 75 can be accurately clamped, thereby limiting the relative rotation of the connecting cylinder 61 and the fixing member 7 under the conditions of equipment operation, vibration, etc. The screw connection limits the axial displacement, thereby further stabilizing the connection and effectively preventing the connection from loosening due to factors such as vibration and external force impact.

[0028] The stable connection can effectively resist the vibration generated by the operation of the high-pressure water pump 4 during the operation of the pipe high-pressure dredging machine, the jolt and sway of the equipment during movement and transportation, and other external force influences, thereby ensuring the continuity of the entire water flow path from the water tank 3 through the high-pressure water pump 4, the water delivery pipe 5, the water guide pipe 9, etc. The high-pressure water can smoothly pass through each connection part with stable pressure and flow rate, thereby ensuring that the high-pressure water can continuously and stably act on the blocked part during pipe dredging, achieving good dredging effect and improving the efficiency and quality of the dredging work. At the same time, there is no need to frequently check, maintain and re-tighten the connection parts, thereby reducing the equipment maintenance workload and maintenance frequency, lowering the labor and material costs and the time cost of equipment downtime maintenance, and improving the use efficiency and economic benefits of the equipment.

[0029] Embodiment 2

[0030] To conveniently realize the screw connection of the fixing member 7, please refer to Figures 1-4 On the basis of embodiment 1, the sliding rails 731 are fixedly arranged on the inner wall of the moving groove 73, and the moving plate 76 is slidingly connected with the sliding rails 731 through the notches on the two sides of the moving plate 76.

[0031] Specifically, when the fixing part 7 is installed or disassembled, the limiting block 75 is inside the moving groove 73, the limiting block 75 is limited by the moving groove 73, the limiting block 75 is prevented from separating from the moving groove 73, the installation or disassembly of the fixing part 7 is facilitated, in the process, the limiting block 75 extrudes the spring 77 through the moving plate 76, so that the spring 77 is in a compressed state, and the pull handle 74 and the limiting block 75 are both in a deflected state, when the fixing part 7 reaches the appropriate position, the operator rotates the pull handle 74, so that the pull handle 74 drives the limiting block 75 to return to the initial state, so that the spring 77 loses external force limitation and returns to the original state, and drives the limiting block 75 to pass through the side wall of the connecting groove 71, the sliding rail 731 can limit the moving plate 76, so that the moving plate 76 does not rotate when the limiting block 75 rotates, thereby preventing the spring 77 from being twisted.

[0032] Working principle: when the device is in use, the water pipe 5 is inserted into the installation cylinder 6, so that the two are connected in place, and the fixing part 7 is prepared to be installed, at this time the limiting block 75 is inside the moving groove 73, the limiting block 75 extrudes the spring 77 through the moving plate 76, the spring 77 is compressed, and the pull handle 74 and the limiting block 75 are both in a deflected state, the fixing part 7 is held, aligned with the connecting cylinder 61, and the fixing part 7 is rotated to start screwing the fixing part 7 with the connecting cylinder 61 through the connecting groove 71, as the fixing part 7 is continuously tightened, the clamping piece 62 on the connecting cylinder 61 gradually enters the extrusion cavity 72 inside the fixing part 7, the inner wall of the extrusion cavity 72 applies extrusion force to the clamping piece 62, so that the clamping piece 62 is clamped from the side to the water pipe 5, and the tightness of the connection is enhanced; when the fixing part 7 is screwed in place, the operator rotates the pull handle 74, so that the pull handle 74 drives the limiting block 75 to return to the initial state, at this time the spring 77 loses external force limitation and starts to return to the original state, and drives the limiting block 75 to pass through the side wall of the connecting groove 71 and accurately insert into the limiting groove 611 outside the connecting cylinder 61. Due to the limitation of the sliding rail 731 to the moving plate 76, the moving plate 76 does not rotate during the rotation and resetting of the limiting block 75, so that the spring 77 is prevented from being twisted, thus the installation of the fixing part 7 and the stable connection between the components are completed, and the connection parts of the device are firm and reliable.
