Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drain pipe dredging, in particular to a dredging device for urban drainage pipes. Background Technique
[0002] Municipal pipe dredging is to remove silt and scale from the underground pipes laid in the city to ensure that the pipes are unobstructed. Once the municipal pipes are blocked, the discharge of domestic water and road rainwater will be affected, bringing inconvenience to people's daily life. Therefore, municipal pipe dredging is an essential task for people's daily life. The existing technology uses a high-pressure flushing device, and the reaction force generated by the high-pressure water jet drives the dredging head forward to wash the sludge and other impurities in the pipe.
[0003] After the high-pressure water scatters the impurities, it is also necessary to drag the head of the dredger outward, and then use the high-pressure water flow to continuously wash the scattered impurities outwards. However, due to the interval setting of the high-pressure nozzles, there will also be gaps in the high-pressure water columns, and it is easy for impurities to not be flushed out once, and it is necessary to move the dredger back and forth multiple times to completely clean the impurities. Therefore, we propose a dredging device for urban drainage pipes. Content of the Utility Model
[0004] The purpose of the utility model is to provide a dredging device for urban drainage pipes. By connecting and fixing a deformable annular hose and a soft cloth at the rear end of the dredging head, when the high-pressure water sprayed by the high-pressure nozzle scatters the sludge and other impurities, the high-pressure water can be supplied into the annular hose to expand it and the soft cloth, and then when pulling it outwards, the annular hose touches the inner wall of the drain pipe, so that the scattered sludge and other impurities can be scraped out, and it is not necessary to move back and forth multiple times to relatively thoroughly clean the impurities, solving the problems raised in the background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A dredging device for urban drainage pipes, including a dredging head and a high-pressure nozzle. A plurality of side grooves are evenly arranged on the outer ring of the surface of the dredging head. The high-pressure nozzle is installed inside the side groove and communicated with the water channel inside the dredging head, and both the side groove and the high-pressure nozzle are inclined towards the tail of the dredging head; an annular hose is arranged at the tail of the dredging head. Spray holes communicated with the inside thereof are evenly opened on the surface of the annular hose. A soft cloth is connected to the side of the annular hose and fixed on the outer ring of the tail of the dredging head. A water inlet pipe communicated with the inside thereof is connected to the tail of the dredging head. A side pipe communicated with the inside thereof is connected to the side of the water inlet pipe, and the side pipe is communicated with the annular hose through a connecting pipe. A first solenoid valve is installed on the water inlet pipe between the side pipe and the dredging head, and a second solenoid valve is installed on the side pipe.
[0006] By adopting the above technical scheme, high-pressure water is first introduced into the inside of the dredging head, and the reaction force of the high-pressure water sprayed backward is used to drive the dredging head forward and disperse the sludge and other impurities inside the drain pipe. Then, the high-pressure water is introduced into the annular hose to stretch it and the soft cloth. When the dredging head is pulled outward, the expanded annular hose is used to touch the inner wall of the drain pipe and cooperate with the soft cloth to scrape out and clean the dispersed sludge and other impurities.
[0007] Optionally, the soft cloth is placed on the outer ring at the end of the dredging head, and the soft cloth is locked on the outer ring at the end of the dredging head through a hoop.
[0008] By adopting the technical solution, the hoop can be removed and the ring tube and the soft cloth can be replaced.
[0009] Optionally, an annular groove is provided on the outer surface of the dredging head where the soft cloth is placed, and the hoop presses the soft cloth tightly into the groove and locks it.
[0010] By adopting the above technical solution, the soft cloth can be locked more firmly to avoid slipping.
[0011] Optionally, pull rings are fixed on the surfaces of the unclogging heads on both sides of the water inlet pipe, and the pull rings are fixed to the surfaces of the unclogging heads by welding.
[0012] By adopting the above technical solution, the pull ring is used to connect the pull rope, so that the dredging head can be pulled.
[0013] Optionally, the top of the dredging head is configured to be a pointed cone.
[0014] By adopting the above technical solution, the dredging head can play a guiding role during its forward movement.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. The technical solution of the present application is to connect and fix a deformable annular hose and a soft cloth at the rear end of the dredging head. After the sludge and other impurities are dispersed by the water sprayed from the high-pressure nozzle, the high-pressure water can be supplied to the annular hose to stretch it and the soft cloth. Then, when it is pulled outward, the annular hose touches the inner wall of the drain pipe, so that the dispersed sludge and other impurities can be scraped out, and the impurities can be cleaned more thoroughly without multiple reciprocating movements.
[0017] 2. The technical solution of the present application realizes the detachable fixation of the soft cloth by using a hoop to be sleeved on the outer ring of the soft cloth and stuck in the ring groove. After a long period of use, the soft cloth and the annular hose that are severely worn can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution: an urban drainage pipe dredging equipment, including a dredging head 1 and a high-pressure nozzle 111. A plurality of side grooves 11 are evenly arranged on the outer ring of the surface of the dredging head 1. The high-pressure nozzle 111 is installed inside the side groove 11 and communicated with the water channel inside the dredging head 1. Both the side groove 11 and the high-pressure nozzle 111 are inclined towards the tail of the dredging head 1. An inlet pipe 4 communicated with its interior is connected to the tail of the dredging head 1. The joint at the end of the inlet pipe 4 can be connected to the water supply pipe. When high-pressure water enters the dredging head 1 and high-pressure water is sprayed from the high-pressure nozzle 111 towards the tail, the reaction force can be used to drive the dredging head 1 to move forward in the pipe and play a role in flushing sludge and other impurities in the pipe. The top of the dredging head 1 is set to be conical. When moving forward, the conical head can play a guiding role in the forward movement of the dredging head 1.
[0023] Pull rings 12 are fixed on the surfaces of both sides of the inlet pipe 4 on the surface of the dredging head 1. The pull rings 12 are fixed on the surface of the dredging head 1 by welding. When cleaning, the pull rings 12 are connected to the pull rings 12. The dredging head 1 can be pulled forward slowly by a pull rope, and the acting force is applied to the pull rope to avoid the water supply pipe being subjected to tension.
[0024] A ring-shaped hose 2 is provided at the tail of the dredging head 1. A soft cloth 3 is connected to the side of the ring-shaped hose 2 close to the dredging head 1. The soft cloth 3 is fixed to the outer ring of the tail of the dredging head 1. Spray holes 21 communicating with its interior are evenly formed on the surface of the ring-shaped hose 2. A side pipe 42 communicating with its interior is connected to the side of the water inlet pipe 4, and the side pipe 42 is communicated with the ring-shaped hose 2 through a connecting pipe 422. A first solenoid valve 41 is installed on the water inlet pipe 4 between the side pipe 42 and the dredging head 1, and a second solenoid valve 421 is installed on the side pipe 42. First, after using the high-pressure nozzle 111 to disperse impurities such as sludge, the first solenoid valve 41 can be closed to stop supplying water to the high-pressure nozzle 111, and the second solenoid valve 421 can be opened to supply water to the ring-shaped hose 2 through the side pipe 42 and the connecting pipe 422 and spray out from the spray holes 21 on its surface. Its interior is filled with high-pressure clear water, which will make the ring-shaped hose 2 in a stretched state and can abut against the inner wall of the drain pipe, and also stretch the soft cloth 3. When pulling the dredging head 1 outward through the pull rope, the dispersed garbage can be taken out to the outside by using the stretched ring-shaped hose 2 and the soft cloth 3 to achieve the cleaning purpose.
[0025] The soft cloth 3 is sleeved on the outer ring of the end of the dredging head 1, and the soft cloth 3 is locked on the outer ring of the end of the dredging head 1 through a hoop 31, so that the hoop 31 can be removed to replace the severely worn ring-shaped hose 2 and the soft cloth 3. In addition, an annular groove 13 is formed on the outer surface of the dredging head 1 at the sleeved position of the soft cloth 3. The hoop 31 presses the soft cloth 3 against the annular groove 13 for locking, so that the soft cloth 3 is pressed in the annular groove 13 to achieve the purpose of relatively firm locking.
[0026] During use, the high-pressure water supply pipe is connected to the water inlet pipe 4 through a joint, the control line is connected to the first solenoid valve 41 and the second solenoid valve 421, and the two connecting pipes 422 of the dredging head 1 are connected to the traction pull rope. The dredging head 1 is placed in the drain pipe to be dredged, and then high-pressure water is supplied to the dredging head 1 through the water inlet pipe 4. The high-pressure water sprays backward from the high-pressure nozzle 111, and then the dredging head 1 can be driven to move forward in the drain pipe by the reaction force. At the same time, the inside of the drain pipe is flushed with high-pressure water to disperse sludge and the like. During this process, the pull rope is tightened and gradually released to make the dredging head 1 move forward slowly for flushing, avoiding large tensile forces on the water supply pipe and the control solenoid valve control line. During the forward movement, since the second solenoid valve 421 is in the closed state, no water enters the ring-shaped hose 2 and both the ring-shaped hose 2 and the soft cloth 3 are in a flaccid state, which will not affect the forward movement of the dredging head 1. When it is necessary to take out the dispersed impurities to the outside, the first solenoid valve 41 can be closed and the second solenoid valve 421 can be opened. High-pressure water enters the ring-shaped hose 2 through the side pipe 42 and the connecting pipe 422 and sprays out from the spray holes 21. Since the ring-shaped hose 2 is filled with high-pressure water, the ring-shaped hose 2 will be fully stretched and abut against the inner wall surface of the pipe. When pulling the dredging head 1 outward, the dispersed garbage can be taken out to the outside by using the stretched ring-shaped hose 2 and the soft cloth 3 to achieve the cleaning purpose.
