Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy dredging technology, and in particular to a hydrological well dredging device. Background Technology
[0002] Hydrological wells are widely used facilities in the fields of hydrogeology and water conservancy. They are used to observe groundwater levels, water quality, and obtain other hydrogeological data. They generally consist of a well casing, a filter pipe, and a sedimentation pipe. The well casing extends deep into the aquifer, the filter pipe prevents surrounding sediment from entering the well, and the sedimentation pipe collects sediment and debris from the bottom of the well. In practical applications, hydrological wells can monitor the dynamic changes in groundwater levels in real time, providing crucial data support for the rational development and utilization of water resources, flood control, and drought relief. For example, in urban water supply planning, long-term monitoring of hydrological well water level data can accurately determine the reserves and trends of groundwater resources, thereby enabling the scientific formulation of water supply plans. Simultaneously, they can also sample and analyze groundwater quality to understand the chemical composition and pollution status of the water body, contributing to environmental protection and water pollution control efforts. They play an indispensable role in ensuring the sustainable use of water resources and the stability of the ecological environment.
[0003] Hydrological well dredging refers to the process of removing silt from wells used for hydrological monitoring. Over long-term use, hydrological wells accumulate sediment, silt, and other impurities carried by the water flow, causing dirt to adhere to the well walls and silt to build up at the bottom. This can seriously affect the normal function of the hydrological well, making dredging crucial. On the one hand, it ensures the accuracy of hydrological monitoring data; with less silt, the measurement of parameters such as well water level and water quality becomes more precise, providing a reliable basis for water conservancy project planning and water resource management. On the other hand, it extends the service life of hydrological wells and prevents damage such as well pipe blockage and corrosion caused by siltation.
[0004] However, existing dredging operations typically employ manual dredging and simple mechanical dredging. Manual dredging is very slow and often consumes a significant amount of time. In mechanically assisted dredging, pumping and suction equipment, due to their simple structure, cannot effectively clean silt from every corner of the well bottom, often requiring multiple operations to complete the dredging, resulting in low efficiency. The preparation and entry of hydrological drilling rigs for dredging are time-consuming. Whether manual or simple mechanical dredging, it is difficult to thoroughly clean the silt at the bottom of the well and reach all parts of the well bottom. Simple mechanical dredging equipment, due to its limited functionality, cannot effectively clean silt in different states (such as highly viscous sludge). Existing simple mechanical dredging equipment is prone to damage when in contact with hard debris at the bottom of the well or in complex underground environments, increasing dredging costs. Therefore, to address these shortcomings, a hydrological well dredging device is proposed to solve the aforementioned problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a hydrological well dredging device, which aims to improve the problem that some existing hydrological well dredging devices do not completely remove silt.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hydrological well dredging device, comprising a submersible pump base and the hydrological well, wherein a submersible pump is installed inside the submersible pump base, and a water pumping and filtering assembly is provided inside the submersible pump. A water delivery steel pipe is fixedly connected to the output end of the submersible pump, and the water delivery steel pipe is fixedly connected via multiple flanges. A left-wing, downward-sloping, rotating return water pipe is fixedly connected to the outer left side of the water delivery steel pipe, and a left-wing, downward-sloping, rotating return water pipe is fixedly connected to the bottom of the return water pipe. The water supply pipe has a right-wing downward-sloping rotating return water pipe fixedly connected to its outer right side, and a right-wing downward-sloping rotating return water nozzle fixedly connected to its bottom. An upward-spraying return water pipe is fixedly connected to the inside of the water supply pipe via clamps and a flange, and an upward-spraying return water nozzle is fixedly connected to its bottom. A generator is installed on the top left side of the hydrological well, and the generator is electrically connected to the submersible pump via a waterproof cable. An adjustment support assembly is provided on the outside of the water supply pipe.
[0007] The above technical solution, consisting of a left-wing downward-sloping rotary return water pipe, a left-wing downward-sloping rotary return water nozzle, a right-wing downward-sloping rotary return water pipe and a right-wing downward-sloping rotary return water nozzle on the outer right side, as well as an upward-spraying return water pipe and a bottom upward-spraying return water nozzle fixedly connected by clamps and flanges, can spray water from different directions to achieve dredging of the hydrological well. The generator is installed on the top left side of the hydrological well and supplies power to the submersible pump through a waterproof cable. An adjustment support component is also installed outside the water supply steel pipe to assist in operation. The entire device achieves the effect of dredging the hydrological well through the process of pumping water, supplying water, and spraying water in different directions.
[0008] As a further description of the above technical solution:
[0009] The water pumping and filtration assembly includes a submersible pump impeller, the exterior of which is disposed inside the submersible pump. A submersible pump filter screen is installed inside the submersible pump, and a waterproof submersible pump motor is installed inside the submersible pump.
[0010] The above technical solution involves a submersible pump impeller driven by a waterproof motor, which pumps water during rotation. When water is pumped into the submersible pump, it passes through a filter screen. This filter screen removes impurities from the water, preventing them from entering subsequent water transport stages. This ensures the stable and efficient operation of the entire hydrological well dredging device, achieving the effect of pumping water and filtering impurities.
[0011] As a further description of the above technical solution:
[0012] The adjustment support assembly includes a wellhead base, the bottom of which is fixedly connected to the top of the hydrological well. A pipe clamp is fixedly connected to the outside of the water conveying steel pipe, and a well pipe bracket is fixedly connected to the outside of the water conveying steel pipe. A valve is installed on the top side of the outside of the water conveying steel pipe.
[0013] Through the above technical solution: the pipe clamp can fasten the water conveying steel pipe, the well pipe support can further support the water conveying steel pipe and enhance its stability, and the valve installed on the top side of the outside of the water conveying steel pipe can control the flow of water in the water conveying steel pipe by opening or closing, thereby adjusting the water output of the entire dredging device.
[0014] As a further description of the above technical solution:
[0015] The hydrological well has an internal groundwater level and a bottom sediment.
[0016] The above technical solution works as follows: When the dredging device is running, the groundwater level is the source of water for the submersible pump. As the pumping process proceeds, the water level will drop, and the silt at the bottom of the well will be the target of the dredging. The dredging device uses water jets from nozzles in different directions, such as the left-wing oblique downward rotating return water nozzle, the right-wing oblique downward rotating return water nozzle, and the upward return water nozzle, to spray water into the silt at the bottom of the well, breaking it up and pumping it away with the water flow. This achieves the effect of cleaning the silt at the bottom of the well and improving the internal environment of the hydrological well.
[0017] As a further description of the above technical solution:
[0018] The clamp is externally fixedly connected to the inside of the water supply steel pipe, and the waterproof cable is externally fixedly connected to the inside of the clamp.
[0019] The above technical solution involves a pipe clamp encircling the water-carrying steel pipe and connecting it to the waterproof cable. This provides stable support for the waterproof cable, preventing it from shaking or tangling during operation, while also ensuring the safety of the waterproof cable and ensuring stable power transmission to the submersible pump, thus maintaining the stable operation of the entire hydrological well dredging device.
[0020] As a further description of the above technical solution:
[0021] The left-wing downward rotating spray return water pipe, the right-wing downward rotating spray return water pipe, and the upward spray return water pipe are fixedly connected to the outside of the water supply steel pipe by the clamp and the flange.
[0022] Through the above technical solution: when the submersible pump works to pump water, the water flows through the water delivery steel pipe, and part of it is diverted to each return water pipe. The nozzles at the bottom of the left and right wing downward rotating return water pipes will rotate due to the impact of the water flow, spraying water downwards at an angle to flush the bottom and lower part of the well wall of the hydrological well from multiple angles and break up the silt.
[0023] As a further description of the above technical solution:
[0024] The groundwater level reflects the water level inside the hydrological well, and the pumping and spraying operations of the device will affect the water level.
[0025] The above technical solution works as follows: when the dredging device is running and the submersible pump is turned on to pump water, the water in the hydrological well will be pumped out through the water pumping and filtering components and transported out through the water delivery steel pipe. This operation reduces the amount of water in the hydrological well, causing the groundwater level to drop.
[0026] As a further description of the above technical solution:
[0027] The generator supplies power to the submersible pump when there is no external power source, and the valve is installed on the water supply pipe to control the flow of water.
[0028] The above technical solution involves installing a valve on the top side of the water supply steel pipe. The valve disc can switch between open and closed states. When the valve disc is open, water can flow smoothly through the water supply steel pipe, allowing the water pumped by the submersible pump to flow through the water supply steel pipe to various return pipes, such as the left-wing downward rotating spray return pipe, the right-wing downward rotating spray return pipe, and the upward spray return pipe, thus realizing the dredging and water spraying operation of the hydrological well. When the valve disc is closed, the water flow is cut off, and the water flow path in the water supply steel pipe is blocked, effectively controlling the water output of the dredging device and achieving precise control of the water flow throughout the dredging process.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, the device can spray water from multiple directions to the bottom of the well in a rotating manner to form a vortex, and can also assist in spraying and transporting silt upwards, which can quickly clean up the silt and greatly improve the sludge removal speed compared with the prior art.
[0031] 2. In this utility model, the rotary spray return water nozzle can make the water flow impact the silt at the bottom of the hydrological well from all directions. No matter what state the silt is in, it can be effectively broken up and cleaned, ensuring thorough dredging and no residue.
[0032] 3. In this utility model, the various components are firmly connected by clamps, pipe clamps, etc., which can withstand the complex underground environment, reduce the possibility of equipment damage, and extend the service life of the equipment. Attached Figure Description

The device is installed inside the hydrological well 21. The submersible pump 1 is installed inside the submersible pump base 5. The submersible pump 1 serves as the power source for pumping water. It generates suction by rotating the submersible pump impeller 2 to draw water in.

[0040] A water delivery steel pipe 15 is fixedly connected to the output end of the submersible pump 1. The water delivery steel pipe 15 is used to transport well water and is of high strength and not easily damaged. The water delivery steel pipe 15 is fixedly connected through multiple flanges 13.

A right-wing oblique downward rotating return water pipe 8 is fixedly connected to the outer right side of the water delivery steel pipe 15. The downward rotating spray return water pipe 6 and the right wing oblique downward rotating spray return water pipe 8 are located on the left and right sides of the device, respectively, and are inclined towards the bottom of the well. They are used to spray water to different positions at the bottom of the well and form a vortex. They are connected to the main body of the submersible pump 1 through threaded connection. The bottom of the right wing oblique downward rotating spray return water pipe 8 is fixedly connected to the right wing oblique downward rotating spray return water nozzle 9. The left wing oblique downward rotating spray return water nozzle 7 and the right wing oblique downward rotating spray return water nozzle 9 are installed at the end of the corresponding return water pipe, which can increase the intensity of the sprayed water flow.
[0041] An upward-spraying return water pipe 10 is fixedly connected to the inside of the water supply steel pipe 15 via clamps 12 and flanges 13. A left-wing downward-sloping rotating return water pipe 6 and a right-wing downward-sloping rotating return water pipe 8 are fixedly connected to the upward-spraying return water pipe 10 on the outside of the water supply steel pipe 15 via clamps 12 and flanges 13. The clamps 12 and flanges 13 are used to connect various pipes and components, ensuring the connection's firmness and sealing. The clamps 12 are fixedly connected externally to the inside of the water supply steel pipe 15. The bottom of the upward-spraying return water pipe 10 is fixedly connected to... The upward-spraying return water nozzle 11 and the upward-spraying return water pipe 10 are arranged vertically upwards to spray the mixture of sediment 23 and water at the bottom of the well into the vicinity of the submersible pump filter screen 3 along the vortex, and finally pump it out of the well. A generator 16 is installed on the top left side of the hydrological well 21. The generator 16 supplies power to the submersible pump 1 when there is no external power. The generator 16 is electrically connected to the submersible pump 1 through a waterproof cable 14. An adjustment support assembly is provided on the outside of the water delivery steel pipe 15.
[0042] Specifically, during operation, the submersible pump base 5 secures the submersible pump 1, ensuring its stable operation. The submersible pump waterproof motor 4 inside the submersible pump 1 drives the submersible pump impeller 2 to rotate, generating suction to draw water from the hydrological well 21. The water first passes through the submersible pump filter screen 3 to filter impurities before entering the water delivery steel pipe 15. The left-wing downward-sloping rotary return water pipe 6 and the right-wing downward-sloping rotary return water pipe 8 are located on both sides of the device, angled towards the bottom of the well. The left-wing downward-sloping rotary return water nozzle 7 and the right-wing downward-sloping rotary return water nozzle 8 are located at their bottoms. Water nozzle 9 sprays water to different positions at the bottom of the well and forms a vortex. The upward spray return water pipe 10 is arranged vertically upward, and the upward spray return water nozzle 11 at its bottom sprays the mixture of silt 23 and water at the bottom of the well along the vortex to the vicinity of the submersible pump filter screen 3, and finally pulls it out of the well. When there is no external power supply, the generator 16 supplies power to the submersible pump 1 through the waterproof cable 14. The adjustment support component outside the water delivery steel pipe 15 ensures the stability of the device. Through the above-mentioned movement process, the device achieves effective silt removal of the hydrological well 21.
[0043] Reference Figures 1 to 3 The adjustment support assembly includes a wellhead base 19, the bottom of which is fixedly connected to the top of the hydrological well 21. A pipe clamp 20 is fixedly connected to the outside of the water supply steel pipe 15 to fix the pipe and prevent it from shifting during operation. A waterproof cable 14 is fixedly connected to the inside of the pipe clamp 20 and connects the submersible pump waterproof motor 4 to an external power source. Its waterproof design ensures electrical safety. A well pipe bracket 18 is fixedly connected to the outside of the water supply steel pipe 15. The well pipe bracket 18 and the wellhead base 19 are used to support and fix the entire dredging device. A valve 17 is installed on the top side of the outside of the water supply steel pipe 15 to control the flow of water. The hydrological well 21 has a groundwater level 22 and a bottom sediment 23. The bottom sediment 23 is the main cleaning target of the device. The groundwater level 22 reflects the water level inside the hydrological well 21. The pumping and spraying operations of the device will affect the water level.
[0044] Specifically, the pipe clamp 20 is fixed to the outside of the water supply steel pipe 15, which can both fix the pipe to prevent displacement and fix the waterproof cable 14 inside it. The waterproof cable 14 connects the submersible pump waterproof motor 4 to the external power supply to ensure electrical safety. The valve 17 is installed on the top side of the outside of the water supply steel pipe 15 to control the water flow. The hydrological well 21 contains a groundwater level 22 that reflects the water level and silt 23 at the bottom of the well, which is the main target for cleaning. When the dredging device is working, the operation of the submersible pump 1 to pump water and the spraying of water from each nozzle will cause the groundwater level 22 to change. Through water pumping and filtration, water supply and water spraying impact from different directions, the silt 23 at the bottom of the well can be cleaned, achieving the effect of dredging.
[0045] Working principle: When this dredging device is working, the submersible pump 1 is started. The submersible pump waterproof motor 4 drives the submersible pump impeller 2 to rotate, generating suction to draw water from the well through the submersible pump filter screen 3. The water is then transported through the water delivery steel pipe 15. Adjusting valve 17 can change the flow rate at the outlet of the water delivery steel pipe 15. The tighter valve 17 is, the more water in the water delivery steel pipe 15 will be sprayed out through the left wing downward rotating spray return pipe 6 and the right wing downward rotating spray return pipe 8, respectively from the left wing downward rotating spray return nozzle 7 and the right wing downward rotating spray return nozzle 9. The high-speed rotating water flow impacts the sediment 23 at the bottom of the well, breaking it up and forming an upward vortex. At the same time, the upward-spraying return water pipe 10, through the upward-spraying return water nozzle 11, uses the upward vortex to spray the mixture of sediment and water at the bottom of the hydrological well 21 onto the vicinity of the submersible pump filter screen 3. Finally, it is sucked into the submersible pump 1 and discharged outside the well, thus achieving sludge removal. When there is no external power supply, the generator 16 supplies power to the submersible pump 1 through the waterproof cable 14. The entire device is fixed by adjusting and supporting components such as the wellhead base 19, pipe clamp 20, and well pipe support 18 to ensure stable operation.
