Description

Technical Field

[0001] This utility model belongs to the field of pipeline dredging technology, specifically relating to a pipeline dredging device. Background Technology

[0002] Over time, municipal pipelines are prone to accumulating silt and becoming clogged due to various factors. This blockage not only disrupts the normal operation of the city's drainage system but can also cause environmental pollution and even pose public health risks. Therefore, it is necessary to use pipeline dredging equipment to clear the blockage promptly.

[0003] In existing technologies, such as the municipal pipeline dredging device with patent application number "CN202422043204.5", the device utilizes the powerful jet force of high-pressure water to quickly unclog pipe blockages, improving dredging efficiency. It can adapt to different types and degrees of pipe blockages by adjusting the working state of the jet orifice. However, the high-pressure nozzle does not have a rotation function during use. Therefore, when the high-pressure water jet is ejected from the hole on the side wall of the high-pressure nozzle, it can only act on a part of the inner wall of the pipe, resulting in a limited cleaning range and thus limiting its cleaning effect. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe unblocking device in which several fan-shaped grooves rotate circumferentially during use, increasing the cleaning range of the inner wall of the pipe and improving the cleaning effect.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipe unblocking device, comprising

[0007] The high-pressure nozzle has a water inlet assembly installed on the right side and a water outlet hole in the middle of the left side. Inside the high-pressure nozzle, two U-shaped mounting rods are fixedly installed in a vertically distributed manner in the center. The high-pressure nozzle has an annular groove around its periphery that matches the position of the two U-shaped mounting rods.

[0008] The assembly ring is rotated and sealed inside the annular groove. Several blades are inclinedly assembled inside the assembly ring. Several assembly holes are opened around the inside of the assembly ring. Several fan-shaped grooves connected to the several assembly holes are inclinedly opened around the periphery of the assembly ring.

[0009] One-way valves are installed inside the water outlet and several assembly holes.

[0010] As a preferred technical solution, pressure boosting blocks are fixedly installed on the inner walls of the front and rear sides of several sector-shaped grooves.

[0011] As a preferred technical solution, the water outlet is a conical hole.

[0012] As a preferred technical solution, the water inlet assembly includes a water inlet pipe, which is fixedly connected to the right side of the high-pressure nozzle. An assembly head is fixedly installed on the right side of the water inlet pipe, and a high-pressure water pipe is fixedly installed inside the assembly head. The other end of the high-pressure water pipe is connected to a high-pressure water pump.

[0013] As a preferred technical solution, the high-pressure nozzle has a bullet-shaped structure.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device achieves its advantages of wide scouring range and good unblocking effect through the synergistic action of initial impact from the water outlet, circumferential rotation and scouring of the fan-shaped groove, and forward propulsion by the inclined water flow; 2. The conical water outlet and the pressure-boosting block at the fan-shaped groove effectively enhance the water jet force, improving the impact on impurities and the cleaning effect on the pipe wall; the bullet-shaped high-pressure nozzle facilitates passage through the pipe, and with the propulsion force of the inclined water flow, it can penetrate deep into the pipe for unblocking; 3. The one-way valves in the water outlet and assembly hole prevent external impurities from entering when not in use, ensuring the cleanliness of the high-pressure nozzle and ensuring its effectiveness in subsequent use.

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-5As shown, this utility model provides a pipe unblocking device, comprising:

[0025] A high-pressure nozzle 1 is provided, and a water inlet assembly 11 is installed on the right side of the high-pressure nozzle 1. The water inlet assembly 11 includes a water inlet pipe 111, which is fixedly connected to the right side of the high-pressure nozzle 1. An assembly head 112 is fixedly installed on the right side of the water inlet pipe 111, and a high-pressure water pipe is fixedly installed inside the assembly head 112. The other end of the high-pressure water pipe is connected to a high-pressure water pump.

[0026] When the pipe needs to be cleared during use, an external high-pressure water pump is started. The high-pressure water pump delivers high-pressure water to the high-pressure water pipe, which then delivers the water to the high-pressure nozzle 1. Since the high-pressure nozzle 1 only has an outlet hole 12 and several assembly holes 17, the high-pressure water is sprayed out through the outlet hole 12 and the assembly holes 17. The outlet hole 12 has a large diameter, so most of the water is sprayed out through the outlet hole 12. Because it is a high-pressure water flow, several fan-shaped grooves 18 can also discharge water under high pressure. Due to the arrangement of several blades 16, when the water flows over the blades 16, it applies a thrust to drive the assembly ring 15. The rotating mechanism causes several fan-shaped grooves 18 to rotate. Due to the shape and structure of the fan-shaped grooves 18, the sprayed water droplets are wider and can cover a larger area of ​​the inner wall of the pipe. Accompanied by the rotation of the assembly ring 15, the inner wall of the pipe is circumferentially flushed. After the water outlet 12 flushes and clears the impurities clogging the inside of the pipe, the water flow sprayed circumferentially by the assembly ring 15 further flushes the inner wall of the pipe. The flushing range is wide and the flushing effect is good. At the same time, since several fan-shaped grooves 18 are opened at an angle, the sprayed water flow is in an inclined state. After contacting the inner wall of the pipe, it will generate a forward thrust, pushing the high-pressure nozzle 1 forward, further improving the pipe clearing effect.

[0027] The high-pressure nozzle 1 has a water outlet 12 in the middle of the left side. The water outlet 12 is a conical hole. When in use, the conical hole reduces the diameter of the water outlet while ensuring structural strength, which can increase the water jet force to a certain extent.

[0028] Two U-shaped mounting rods 13 are fixedly installed in the center of the high-pressure nozzle 1, arranged vertically. An annular groove 14 matching the position of the two U-shaped mounting rods 13 is opened around the high-pressure nozzle 1.

[0029] Assembly ring 15 is rotatably sealed and assembled inside annular groove 14. Several blades 16 are obliquely assembled inside assembly ring 15. Several assembly holes 17 are opened around the inside of assembly ring 15. Several fan-shaped grooves 18 that communicate with several assembly holes 17 are obliquely opened around the periphery of assembly ring 15.

[0030] One-way valves are provided inside the water outlet 12 and several assembly holes 17. The one-way valves can prevent external impurities from entering the high-pressure nozzle 1 when it is not in use.

[0031] A pressure boosting block 2 is fixedly installed on the inner walls of the front and rear sides of several fan-shaped grooves 18. During use, due to the setting of the pressure boosting block 2, the distance between the front and rear grooves is reduced while the width of the groove opening area of ​​the fan-shaped groove 18 remains unchanged. This reduces the groove opening area and reasonably reduces the water outlet, which can significantly enhance the jet force of the water flow.

[0032] The high-pressure nozzle 1 has a bullet-shaped structure; this type of high-pressure nozzle 1 is more convenient to travel through pipes.

[0033] The device is used as follows:

[0034] During use, before unclogging the pipes, the one-way valves in the water outlet 12 and assembly hole 17 can prevent external impurities from entering the high-pressure nozzle 1. When the external high-pressure water pump is started, the high-pressure water flows through the high-pressure water pipe, assembly head 112, and inlet pipe 111 to the high-pressure nozzle 1. Because the diameter of the water outlet 12 is relatively large, most of the water flow first sprays out from the conical water outlet 12. The conical hole reduces the outlet while ensuring structural strength, enhancing the water jet force and impacting the impurities blocking the pipe to achieve initial unclogging. At the same time, the high-pressure water flow pushes open the one-way valve in the assembly hole 17 and enters the fan-shaped groove 18. The pressure boosting block 2 at the fan-shaped groove 18 reduces the groove area, further enhancing the water jet force. When the water flow washes over the blades 16, it pushes the assembly ring 15 to rotate within the annular groove 14, causing several fan-shaped grooves 18 to rotate synchronously. The shape of the fan-shaped grooves 18 makes the sprayed water flow wider, and because the fan-shaped grooves 18 are opened at an angle, the water flow is sprayed out at an angle. On the one hand, it rotates circumferentially to wash the inner wall of the pipe, thoroughly cleaning the pipe after initial unblocking; on the other hand, the water flow generates a forward thrust after contacting the inner wall of the pipe, pushing the bullet-shaped high-pressure nozzle 1 forward in the pipe, expanding the unblocking range.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
