Description

Technical Field

[0001] This utility model relates to the field of sewer dredging technology, specifically to a high-pressure water dredging device for urban sewers. Background Technology

[0002] Over time, urban sewers accumulate large amounts of dirt and debris, such as grease, silt, and garbage, leading to blockages and poor drainage. High-pressure water jet cleaning devices utilize the impact force of high-pressure water to effectively remove these blockages, restoring smooth flow to the sewers, ensuring the normal operation of the urban drainage system, and preventing problems such as flooding.

[0003] Existing high-pressure water unblocking devices for urban sewers mostly use high-pressure nozzles to enter the pipes for unblocking. Although they can handle many blockage situations, when encountering stubborn blockages, the unblocking effect is not ideal when relying solely on the impact of high-pressure water jets on the stubborn blockages. In addition, traditional high-pressure water unblocking devices are mostly large unblocking vehicles, which are difficult to operate in narrow spaces.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0024] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0025] like Figures 1 to 4 As shown, an embodiment of this utility model provides a high-pressure water unblocking device for urban sewers, comprising: a fixing component, fixedly connected to the outer wall of the nozzle 1; a water outlet, fixedly connected to the top of the nozzle 1, so as to realize that the water outlet supplies water to the nozzle 1 for unblocking the sewer; and a rotating part, fixedly connected to the bottom of the fixing component and fixedly connected to the inner wall of the bottom of the nozzle 1, so as to realize that while the nozzle 1 unblocks the sewer, the rotating part rotates and breaks up stubborn blockages in the pipe.

[0026] In this embodiment of the utility model, a water outlet and a nozzle 1 are provided. Water is supplied from the water outlet and sprayed from the nozzle 1 to flush and unclog the inner wall of the pipe. A rotating part is provided so that when the nozzle 1 sprays water, it can rotate and break up stubborn blockages inside the pipe, thereby assisting the nozzle 1 in unblocking the pipe and achieving a better unblocking effect.

[0027] When the nozzle 1 sprays high-pressure water, since the nozzle 1 has a main outlet and a side outlet, the side outlet is angled toward the tail of the nozzle 1, which pushes the nozzle 1 forward in the pipe. The main outlet is located at the center of the end of the nozzle 1, and the high-pressure water jet clears the pipe. There are three side outlets, which makes the nozzle 1 move smoothly in the pipe.

[0028] like Figures 1 to 4As shown, it also includes: a support part, which is fixedly connected to the bottom of the water outlet part; a protective part, which is fixedly connected to the top of the support part; and a movable part, which is rotatably connected to the bottom of the support part.

[0029] In this embodiment of the utility model, a support part is provided to provide basic support for the device, making the device easy to unclog. A protective part is provided to protect the motor and high-pressure water pump 8, reducing the adverse effects of the external environment and extending the service life of the drive device. A movable part is provided so that the device can be easily moved to a suitable position when needed, and the movable part has a self-locking function when it does not need to be moved, ensuring stable operation of the device.

[0030] like Figures 1 to 4 As shown, the rotating part includes: a sleeve 2, which is fixedly connected to the bottom of the fixed assembly; a connecting rod 3, one end of which is fixedly connected to the inner wall of the sleeve 2; a conical diverter block 4, which is disposed at the other end of the connecting rod 3; a motor 5, which is disposed in the bottom groove of the conical diverter block 4 and is fixedly connected to the conical diverter block 4; and a rotating head 6, which is fixedly connected to the output end of the motor 5.

[0031] In this embodiment of the utility model, by setting up the sleeve 2 and the conical diverter 4, the circular high-pressure water column originally located at the center of the nozzle 1 is diverted into an annular high-pressure water column to unclog the pipe. Then, the rotating head 4 is driven by the motor 5 to rotate, which helps to unclog the pipe and break up stubborn blockages. In addition, the motor 5 here has waterproof characteristics, which is prior art and will not be explained in detail. The rotating head 6 here is composed of multiple blades connected in a cross shape, and the bottom of the rotating head 6 is conical, which makes the rotation and breaking ability stronger.

[0032] like Figures 1 to 4 As shown, the water outlet includes: a water pipe 7, one end of which is fixedly connected to the nozzle 1; a high-pressure water pump 8, the outlet of which is fixedly connected to the other end of the water pipe 7; a motor 9, which is fixedly connected to the high-pressure water pump 8; and a water storage tank 10, the inlet of which is fixedly connected to the outlet of the water storage tank 10. The water storage tank 10 is provided with a transparent viewing window for easy observation of the water level. In addition, all connections of the components with water flow in this device are equipped with sealing waterproof gaskets, which are not shown in the figure.

[0033] In this embodiment of the utility model, the high-pressure water pump 8 and the water pipe 7 are arranged to ensure that the water inside the water storage tank 10 is sprayed out from the nozzle 1 in the form of high pressure through the water pipe 7. High-pressure water is the basis for pipe dredging. With the setting of the second motor 9, the high-pressure water pump 8 uses the mechanical energy output by the second motor 9 to pressurize the water and realize high-pressure water spraying operation. The specific working principle is the prior art and will not be explained in detail.

[0034] like Figures 1 to 4As shown, the fixing assembly includes: flange 11, which is fixedly connected to the outer wall of the nozzle 1; flange 2 12, which is disposed on the rotating part and fixedly connected to the outer wall of the rotating part; sealing gasket 13, which is disposed between flange 11 and flange 2 12 and fixedly connected to flange 11; and fixing screw 14, which passes through flange 11 and flange 2 12.

[0035] In this embodiment of the utility model, the rotating part can be disassembled from the outer wall of the nozzle 1 by means of two flanges and fixing screws 14. When the rotating part is partially damaged, it can be removed for repair or replacement by means of two flanges and fixing screws 14, thus saving resources.

[0036] The sealing gasket 13 is placed between the two flanges to prevent high-pressure water from leaking from the connection between the nozzle 1 and the rotating part when the nozzle 1 is in operation after the rotating part is connected to the nozzle 1, thereby ensuring that the water sprayed by the nozzle 1 is continuously under high pressure.

[0037] like Figures 1 to 4 As shown, the support includes: a rotating shaft 15, with the water pipe 7 sleeved on its outer wall; a support frame 16, the top of which is rotatably connected to the rotating shaft 15; a motor 17, the output end of which is fixedly connected to the rotating shaft 15; a support column 18, which is fixedly connected to the motor 17; and a base plate 19, which is fixedly connected to the support column 18.

[0038] In this embodiment of the invention, a support portion is provided to specifically support the water outlet portion, ensuring stable and unobstructed flow of the device.

[0039] like Figures 1 to 4 As shown, the protective part includes: a protective cover 20, which is fixedly connected to the base plate 19 and surrounds the outer wall of the motor 17 and the support column 18; and a protective cover 21, which is fixedly connected to the base plate 19 and surrounds the outer wall of the motor 9 and the high-pressure water pump 8.

[0040] In this embodiment of the utility model, the motor 17 is protected by a protective cover 20, and the motor 9 and the high-pressure water pump 8 are protected by a protective cover 21, thereby reducing the adverse effects of external environmental factors on the drive device.

[0041] like Figures 1 to 4 As shown, the movable part includes: four sets of casters 22, which are rotatably connected to the base plate 19; and a push handle 23, which is fixedly connected to the base plate 19.

[0042] In this embodiment of the utility model, the inclusion of casters 22 and a push handle 23 facilitates the replacement of the device with different work areas. The overall size of the device is reduced, making it highly flexible and suitable for small sections of urban sewers. This avoids the situation where traditional pipe cleaning devices, due to their large size, are unsuitable for narrow pipe environments. Furthermore, the casters 22 have a self-locking function. During cleaning operations, the self-locking function can be used to lock the device, ensuring stable operation. The self-locking function of the casters 22 is existing technology and will not be explained in detail here.

[0043] In a preferred embodiment of this utility model, by setting the device to an appropriate size and combining it with a structure that is easy to move, it is convenient to carry out dredging work on sewers in narrow spaces or areas that are difficult for large dredging vehicles to reach.

[0044] Working principle: When in use, start motor 3 17 drives the rotating shaft 15 to rotate, extend the water pipe 7, and place the nozzle 1 into the blocked pipe. Start motor 2 9 drives the high-pressure water pump 8 to pressurize the static water in the water storage tank 10 and spray it out from the nozzle 1 through the water pipe 7. The nozzle 1 has a main outlet and a side outlet. The side outlet is angled towards the tail of the nozzle 1, pushing the nozzle 1 forward in the pipe. Since the sleeve 2 of the rotating part is connected to the nozzle 1, the water column at the main outlet of the nozzle 1 changes from a circle to an annular shape, impacting and clearing the blockage. When encountering stubborn blockages, start motor 1 5 drives the rotating head 6 of the rotating part to rotate and break it, assisting in clearing the blockage.

[0045] When finished using the device, motor 15 can be stopped, and the high-pressure water jet from nozzle 1 can be used to rinse the dirt around the pipe. Then, motor 317 can be started to drive shaft 15 to rotate, and water pipe 7 can be rewound around the outer wall of shaft 15 for easy and proper storage.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
