Description

Technical Field

[0001] This utility model relates to a dredging device, specifically a water supply and drainage dredging and sewage discharge device, belonging to the field of pipeline dredging technology. Background Technology

[0002] In urban water supply and drainage systems, pipe dredging is of paramount importance. Over time, a large amount of silt and debris accumulates in the pipes, which not only affects drainage efficiency but may also lead to pipe blockages and sewage overflows, causing adverse effects on the urban environment and residents' lives.

[0003] However, current common pipeline dredging methods have some shortcomings. Some manual dredging methods are inefficient, labor-intensive, and require dredging personnel to work in harsh environments, posing certain safety risks. Existing mechanical dredging equipment mostly relies on a single sludge pump, which has limited functionality and is ineffective at handling stubborn sludge buildup. When the sludge in the pipeline has low water content, it becomes semi-dry and hard, with extremely poor fluidity. In this case, the sludge pump not only struggles to remove the sludge but may also clog the pump inlet, causing equipment shutdown. Therefore, developing a highly efficient, flexible, and effective sludge collection and treatment device for water supply and drainage dredging and sewage discharge is of significant practical importance. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this utility model is to provide a water supply and drainage dredging and sewage discharge device to solve the above-mentioned problems, so as to solve the problems of manual dredging in the prior art, which is labor-intensive and has high safety risks; and traditional mechanical dredging, which is difficult to deal with the problem of stubborn silt accumulation.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: a water supply and drainage dredging and sewage discharge device, comprising a mobile vehicle, an automatic dredging mechanism installed on the side of the mobile vehicle, the automatic dredging mechanism comprising a collection box, a collection winnowing basket, a sludge pump, an annular pipe, a water spray head, a water pump, a drive motor, a spiral push rod, and a spiral head; the side end of the collection box is open, the collection winnowing basket is connected to the opening at the side end of the collection box, the lower sludge pump is located inside the collection box, the drive end of the drive motor is connected to the spiral push rod, and the mobile vehicle serves as the carrier of the entire device. The system is used to drive the automatic sludge removal mechanism to move within the water supply and drainage pipeline. The collection hopper can easily send sludge and sewage into the collection box, and the sludge pump will extract the mixed sludge and sewage from the collection box together. The drive motor is used to drive the spiral push rod and spiral head to rotate. The rotation of the spiral push rod can quickly push the sludge into the collection box, and the rotation of the spiral head can effectively break up the solidified sludge blocks. The water pump draws external water to inject water into the ring pipe, and the water spray head sprays water to wash the inner wall of the pipe. The water flow mixes with the sludge to improve its fluidity, thereby facilitating the sludge pump to extract it.

[0006] Preferably, the mobile vehicle is provided with drive wheels on both sides, and anti-slip grooves are provided on the outer ends of the drive wheels. A driver is provided inside the mobile vehicle and is connected to the drive wheels. The drive wheels are made of wear-resistant rubber material, and their diameter is determined according to the overall design of the mobile vehicle and the working environment. The anti-slip grooves on their outer ends can significantly increase the friction between the drive wheels and the inner wall of the pipe, which can effectively prevent the drive wheels from slipping and ensure the stability and safety of the mobile vehicle. The driver is electrically driven and contains components such as a motor and a reducer to provide power for the drive wheels.

[0007] Preferably, the side end of the mobile vehicle is connected to the automatic sludge removal mechanism via a flange, and a transmission line is connected to the rear end of the mobile vehicle. The end of the transmission line is connected to a control panel. The flange connection consists of two disc-shaped flanges with bolt holes, which are respectively fixed to the side end of the mobile vehicle and the automatic sludge removal mechanism. The two flanges are tightly connected together by bolts. The transmission line is a multi-core shielded cable, which contains power lines, control lines, and other circuits for transmitting power and control signals. The control panel is equipped with various function buttons and a display screen that shows the operating status of the equipment. The operator can easily control the driving direction and speed of the mobile vehicle, as well as the start, stop, and operating parameters of each component of the automatic sludge removal mechanism through the control panel.

[0008] Preferably, a protective box is connected to the rear end of the collection box, the sludge pump is connected to the side of the protective box, and the drive motor is connected inside the protective box. The protective box provides an installation base for the sludge pump, enabling the sludge pump to be installed and fixed. At the same time, it can effectively protect the internal drive motor from external impacts, moisture, corrosion, etc., providing a relatively stable and safe working environment for the drive motor and extending the service life of the drive motor.

[0009] Preferably, the spiral push rod is rotatably connected inside the collection box, and its entire body is located at the upper end of the collection hopper. The spiral head is connected to the front end of the spiral push rod, which is located at the front end of the collection hopper. The spiral push rod is a cylindrical metal rod with continuous spiral blades processed on its surface. The pitch and diameter of the blades are designed according to the dredging efficiency and sludge characteristics. The spiral head is conical, which helps to better break up solidified sludge blocks during rotation.

[0010] Preferably, the upper end of the sludge pump is connected to a sludge discharge pipe, and the side end of the annular pipe is connected to a water pump. The tail end of the water pump is connected to the water pump. The sludge discharge pipe is used to discharge the sludge pumped by the sludge pump into the water supply and drainage pipeline. The tail end of the sludge discharge pipe is located outside the water supply and drainage pipeline and can be connected to a transport vehicle to facilitate the collection of the discharged sludge. The water pump is connected to an external water source, which draws water from the water source and then pressurizes and delivers the water to the annular pipe through the water pump to provide sufficient pressure flushing water for the spray head.

[0011] Preferably, the spray head is connected to the side end of the annular pipe and is inclined toward the spiral head end. A support frame is connected to the side end of the annular pipe and the support frame is connected to the upper end of the collection basket. The inclined arrangement of the spray head allows the sprayed water to be directed toward the front end, which facilitates rinsing the inner wall of the pipe and allows the cleaned sewage to mix with the sludge. The support frame is used to support and fix the annular pipe.

[0012] Preferably, a support rod is connected to the lower end of the support frame, and the tail end of the spiral push rod is rotatably connected inside the support rod. The support rod is located on the side end of the spiral head, and support wheels are connected to both sides of the collection box and the collection hopper. The support rod provides additional support at the connection between the spiral push rod and the spiral head, enhancing the stability of the spiral push rod during rotation and reducing vibration and swaying caused by uneven force on the spiral head. When the mobile vehicle drives the automatic sludge removal mechanism, the support wheels can assist the collection box and the collection hopper in moving within the pipeline, reducing friction with the inner wall of the pipeline and reducing equipment wear.

[0013] This utility model provides a water supply and drainage dredging and sewage discharge device, which has the following beneficial effects: 1. This water supply and drainage dredging and sewage discharge device is equipped with an automatic dredging mechanism. Driven by a mobile vehicle, it can move within the water supply and drainage pipeline. The drive motor starts and rotates the spiral push rod, pushing the sludge towards the collection hopper and finally into the collection box. The water pump injects water through a ring pipe, allowing the water nozzle to flush the inner wall of the pipeline, and the flushing water can enter the collection box through the collection hopper. In conjunction with the sludge pump, the sludge and sewage in the collection box can be discharged together. The device relies on the mobile vehicle to move autonomously within the pipeline, eliminating the need for manual entry into the harsh pipeline environment, reducing the intensity of manual operation and safety risks, and enabling continuous operation to improve overall construction efficiency. The ring pipe not only improves cleanliness but also mixes with the sludge to form slurry, increasing its fluidity and facilitating extraction by the sludge pump.

[0014] 2. This water supply and drainage dredging and sewage discharge device is equipped with a spiral head that rotates with a spiral push rod. The spiral head can break up solidified sludge lumps, crushing large solid sludge lumps into smaller particles. Then, water is sprayed through the annular pipe to dissolve and mix the sludge, allowing it to be smoothly pushed to the collection sieve and into the collection box. Therefore, the device can achieve a series of sludge dredging processes of "crushing - stirring and pushing - mixing with water - extraction", which can effectively avoid device jamming caused by hard blocks, improve the sludge dredging capacity and enhance the applicability of the device.
