Description

Technical Field

[0001] This application relates to the field of dredging equipment technology, and in particular to a safe dredging device. Background Technology

[0002] Water tank dredging is an important task that drainage departments cannot ignore. Whether it is industrial water recycling or wastewater treatment, the silt and impurities accumulated in the water tank must be cleaned regularly. If it is not cleaned in time, it will lead to a series of serious equipment problems such as water pump blockage, filter screen blockage, and pipe blockage.

[0003] In related technologies, the pool needs to be completely emptied before cleaning, which wastes a lot of water resources. In addition, it is time-consuming and laborious for people to enter the pool and use dredging tools to remove the silt accumulated in the pool. There may be a series of safety problems such as silt collapse and poor air circulation in the pool. Therefore, it needs to be improved. Utility Model Content

[0004] To address the problems of water consumption, time and labor costs associated with cleaning and draining water tanks, this application provides a safe dredging device.

[0005] The safe dredging device provided in this application adopts the following technical solution:

[0006] A safe dredging device includes a frame, a water pump, and a spraying mechanism. The water pump is arranged inside the frame, with a suction port at the bottom of the pump in a funnel shape and an outlet at the top. Guide blocks are slidably connected to both sides of the frame, and a lead screw is horizontally arranged between the two guide blocks. A rope is arranged at the top of the water pump, wrapped around the lead screw, and extends outward from the frame. The spraying mechanism is arranged around the outside of the water pump.

[0007] Because the pool needs to be completely emptied before cleaning, which wastes a lot of water resources, and it is time-consuming and laborious to manually enter the pool and use sludge removal tools to remove the accumulated sludge, there may be a series of safety problems such as sludge collapse and poor air circulation in the pool; By adopting the above technical solution, including a frame, a water pump and a spraying mechanism, the water inlet and outlet are installed on the water pump, two guide blocks are slidably connected on both sides of the frame, the screw rod is horizontally installed on the two guide blocks, one end of the rope is fixed to the top of the water pump, the other end of the rope is wrapped around the screw rod and extends outwards from the mining machine, and the spraying mechanism is arranged around the outside of the water pump;

[0008] When cleaning the pool, the frame is fixed to the external structure and positioned above the pool. The vertical position of the water pump is adjusted by ropes so that the pump suction port is close to the surface of the sludge layer at the bottom of the pool. The pump is started, and the loose sludge at the bottom of the pool is sucked into the pump through the funnel-shaped suction port under negative pressure. The sludge is pressurized by the pump and discharged from the outlet. It is then transported through pipelines to an external sludge collection system (such as a sedimentation tank or dewatering equipment). When the pump moves to the hardened sludge area, the suction at the suction port decreases or the flow rate at the outlet decreases. The spray mechanism is then activated, and the high-pressure water jet impacts the hardened sludge, breaking it down and forming a pumpable sludge. The sludge is then pumped out and cleaned until the entire bottom of the pool is completely cleaned.

[0009] By incorporating a frame, water pump, and spraying mechanism, the system optimizes dredging operations in water tanks. It allows for continuous operation during normal water circulation without draining the tank, efficiently pumping out bottom sludge and avoiding system downtime caused by traditional dredging methods. This significantly saves time and labor costs. Furthermore, the device features a fully external control structure, allowing personnel to precisely cover the entire tank area through six-directional movement without entering the tank, completely eliminating safety hazards such as collapse. This results in outstanding safety benefits. Combined with the high-pressure spraying mechanism, it can directionally spray high-pressure water jets to quickly break up hard mud layers and pump them out simultaneously, meeting the dredging needs of complex sites.

[0010] Optionally, the spraying mechanism includes a high-pressure spray ring, a high-pressure water inlet pipe, and several high-pressure nozzles. The high-pressure spray ring is connected to the outside of the water pump, the high-pressure water inlet pipe is connected to the high-pressure spray ring, and the several high-pressure nozzles are all connected to the bottom of the high-pressure spray ring and are arranged with the nozzles facing downwards.

[0011] By adopting the above technical solution, the spraying mechanism includes a high-pressure spray ring, a high-pressure water inlet pipe, and several high-pressure nozzles. When the high-pressure water inlet pipe is opened, high-pressure water enters the high-pressure spray ring through the high-pressure water inlet pipe, and is sprayed onto the bottom of the pool in the form of a high-pressure water jet through the evenly distributed high-pressure nozzles. The high-pressure water jet impacts the hardened sludge, breaking it down and loosening it into an extractable slurry state, which is then sucked out for cleaning. Through the setting of the spraying mechanism, continuous sludge cleaning operation is achieved by simultaneously impacting and sucking, ensuring that stubborn sludge is broken down without dead angles, improving the efficiency and thoroughness of sludge cleaning, and is suitable for the needs of cleaning hardened sludge under continuous operation conditions of water pools.

[0012] Optionally, several of the high-pressure nozzles are evenly distributed along the circumference of the high-pressure spray ring.

[0013] By adopting the above technical solution, several high-pressure nozzles are evenly distributed along the circumference of the high-pressure spray ring; by setting the arrangement of the high-pressure nozzles, the impact coverage range is expanded by the circumferentially arranged nozzles, thereby improving the crushing efficiency of stubborn sludge.

[0014] Optionally, the high-pressure spray ring is provided with a fixing ring for connecting to the outside of the water pump.

[0015] By adopting the above technical solution, the high-pressure spray ring is installed on the outside of the water pump through a fixing ring; the setting of the fixing ring ensures the stability of the connection between the high-pressure spray ring and the water pump, avoids the spray ring from shifting due to vibration or water flow impact, and thus ensures the precise impact effect of the high-pressure water jet on the silt at the bottom of the pool.

[0016] Optionally, guide grooves are provided on both sides of the frame, the guide block is slidably connected in the corresponding guide groove, a guide rail is provided in the guide groove, and a sliding groove that cooperates with the guide rail is provided at the bottom of the guide block.

[0017] By adopting the above technical solution, guide grooves are opened on both sides of the frame, and guide rails are installed in the guide grooves. Guide blocks slide in the guide grooves, and sliding grooves are opened at the bottom of the guide grooves, which cooperate with the guide rails. Through the setting of guide grooves, guide rails and sliding grooves, the guide grooves provide a stable movement path for the overall movement of the water pump and spraying mechanism, effectively preventing movement deviation and improving the stability of the overall movement.

[0018] Optionally, the lead screw passes through two guide blocks, one of which is threadedly connected to the lead screw, and the other guide block has a through hole for the lead screw to pass through.

[0019] By adopting the above technical solution, the lead screw passes through two guide blocks. One guide block is threadedly connected to the lead screw, and the other guide block has a through hole for the lead screw to pass through. The lead screw can be rotated by rotating the handle wheel to achieve left and right coverage, and drive the guide block to slide along the guide groove, thereby moving the water pump in the front and back directions to achieve front and back coverage. The above movement operation is repeated according to the preset path until the entire bottom of the pool is completely cleaned. By setting the connection method between the lead screw and the guide block, the rotational motion is converted into linear displacement, ensuring that the water pump spray nozzle is always aligned with the target sludge removal area, improving the movement stability of the device under complex working conditions, and achieving efficient and thorough cleaning of the entire bottom area of ​​the pool.

[0020] Optionally, the lead screw is provided with a handle wheel for operation, and the handle wheel is fixedly disposed at the end of the lead screw.

[0021] By adopting the above technical solution, the handle wheel is fixed to the end of the lead screw; by setting the handle wheel, the lead screw can be directly driven to rotate by rotating the handle wheel without the need for additional tools. The addition of the handle wheel amplifies the rotation torque and reduces the operating intensity.

[0022] Optionally, a guide wheel for guiding the rope is provided in the middle of the lead screw, and a cable groove for the rope to pass through is also provided on the frame.

[0023] By adopting the above technical solution, the guide wheel is installed in the middle of the lead screw, and the cable groove is opened on the frame. Through the setting of the guide wheel and the cable groove, the guide wheel avoids wear or jamming caused by direct friction between the cable and the lead screw, realizes the guidance of the cable, and extends the service life of the cable. At the same time, the cable groove on the frame prevents external debris from getting tangled and facilitates the cable to pass through.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Through the design of the frame, water pump, and spraying mechanism, the dredging operation of the water tank is optimized. It can operate continuously during the normal water circulation of the water tank and can efficiently suck up the bottom sludge without draining the water. This avoids the system shutdown caused by traditional dredging and significantly saves time and labor costs. At the same time, the device adopts a fully external control structure, which allows personnel to accurately cover the entire pool area through six-way movement without entering the pool. This completely eliminates safety hazards such as collapse and has outstanding safety benefits. In addition, combined with the high-pressure spraying mechanism, it can spray high-pressure water jets in a directional manner to quickly break up hard mud layers and suck them up simultaneously, meeting the dredging needs of complex sites.

[0026] 2. By setting up a spraying mechanism, continuous sludge removal operations can be achieved by simultaneously impacting and suctioning, ensuring that stubborn sludge is broken up without dead angles, improving sludge removal efficiency and thoroughness, and is suitable for the cleaning needs of hardened sludge under continuous operation conditions of water tanks.

[0027] 3. By using the connection between the lead screw and the guide block, the rotational motion is converted into linear displacement, ensuring that the water pump spray nozzle is always aligned with the target sludge removal area. This improves the stability of the device under complex working conditions and enables efficient and thorough cleaning of the entire bottom area of ​​the pool. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a safe dredging device. (Refer to...) Figure 1 The safety dredging device includes a frame 1. In this embodiment, the frame 1 is fixedly installed on the external structure so that the frame 1 is located above the water pool. A water pump 2 is installed inside the frame 1. The surface of the water pump 2 is waterproofed. The water pump 2 is inserted into the water pool to pump out the silt from the water pool.

[0034] Reference Figure 1 The bottom of the water pump 2 is formed with a suction port 21, which is funnel-shaped. At the same time, the top of the water pump 2 is formed with a water outlet 22. In this embodiment, the water outlet 22 is connected to a pipe to discharge the sludge. When the water pump 2 is started, the loose sludge at the bottom of the pool is sucked into the water pump 2 through the funnel-shaped suction port 21 under negative pressure. After the sludge is pressurized by the water pump 2, it is discharged from the water outlet 22 and transported to an external sludge collection system (such as a sedimentation tank, dewatering equipment, etc.) through a pipe.

[0035] Reference Figure 1 and Figure 2 A spray mechanism 3 is installed on the outside of the water pump 2. The spray mechanism 3 includes a high-pressure spray ring 31, a high-pressure water inlet pipe 32, and several high-pressure nozzles 33. The high-pressure spray ring 31 is installed around the outside of the water pump 2. A fixing ring 7 is installed between the high-pressure spray ring 31 and the outside of the water pump 2. The fixing ring 7 ensures the stability of the connection between the high-pressure spray ring 31 and the water pump 2, and avoids the spray ring from shifting due to vibration or water flow impact, thereby ensuring the precise impact effect of the high-pressure water jet on the silt at the bottom of the pool.

[0036] Reference Figure 1 The high-pressure water inlet pipe 32 is connected to the high-pressure spray ring 31, and several high-pressure nozzles 33 are connected to the bottom of the high-pressure spray ring 31. The several high-pressure nozzles 33 are evenly distributed along the circumference of the high-pressure spray ring 31 and are arranged downwards. The impact coverage range is expanded by the circumferentially arranged nozzles, thereby improving the crushing efficiency of stubborn sludge.

[0037] Reference Figure 1 and Figure 3 Guide grooves 8 are provided on both sides of the frame 1. In this embodiment, the guide grooves 8 are provided along the length of the frame 1. A guide block 4 is slidably connected in each guide groove 8, and a guide rail 9 is also formed in the guide groove 8. A sliding groove 41 that cooperates with the guide rail 9 is provided at the bottom of the guide block 4.

[0038] Reference Figure 1 and Figure 3A lead screw 5 is horizontally installed between two guide blocks 4. A guide wheel 11 is installed in the middle of the lead screw 5. A rope 6 is installed on the top of the water pump 2. A cable groove 12 is provided on the frame 1 for the rope 6 to pass through. One end of the rope 6 is fixed to the top of the water pump 2. The other end of the rope 6 is wound around the guide wheel 11 and passes through the corresponding cable groove 12. In this embodiment, there are two cable grooves 12. The two cable grooves 12 are respectively opened on both sides of the frame 1. At the same time, these two cable grooves 12 and the two guide grooves 8 are located on different sides of the frame 1. The guide wheel 11 avoids wear or jamming caused by direct friction between the rope 6 and the lead screw 5, realizes the guidance of the rope 6, and extends the service life of the rope 6. At the same time, the cable groove 12 on the frame 1 prevents external debris from getting tangled and facilitates the passage of the rope 6.

[0039] Reference Figure 1 and Figure 3 In this embodiment, the lead screw 5 passes through two guide blocks 4. One guide block 4 is threadedly connected to the lead screw 5, and the other guide block 4 has a through hole for the lead screw 5 to pass through. The diameter of the through hole is slightly larger than the diameter of the lead screw 5 so that the lead screw 5 can pass through. At the same time, a handle wheel 10 is sleeved and fixed at the end of the lead screw 5 to convert the rotational motion into linear displacement, ensuring that the spray nozzle of the water pump 2 is always aligned with the target sludge removal area, improving the motion stability of the device under complex working conditions, and realizing efficient and dead-angle-free cleaning of the entire area at the bottom of the pool.

[0040] The implementation principle of a safe sludge removal device according to an embodiment of this application is as follows: When cleaning a water tank, the frame 1 is fixedly installed on the external structure, with the frame 1 located above the water tank. The vertical position (up and down) of the water pump 2 is adjusted by the rope 6 so that the suction port 21 of the water pump 2 is close to the surface of the sludge layer at the bottom of the water tank. The water pump 2 is started, and the loose sludge at the bottom of the tank is sucked into the water pump 2 through the funnel-shaped suction port 21 under negative pressure. After being pressurized by the water pump 2, the sludge is discharged from the outlet 22 and transported through a pipeline to an external sludge collection system (such as a sedimentation tank, dewatering equipment, etc.). When the water pump 2 moves to the hardened sludge area, the suction force of the suction port 21 decreases. If the flow rate at outlet 22 decreases, the high-pressure water inlet pipe 32 is opened. The high-pressure water enters the high-pressure spray ring 31 through the high-pressure water inlet pipe 32 and is sprayed onto the bottom of the pool in the form of a high-pressure water jet through the evenly distributed high-pressure nozzles 33. The high-pressure water jet impacts the plated sludge, breaking it down and loosening it into a slurry that can be pumped out. During this process, the screw 5 can be rotated by rotating the handle wheel 10 to achieve left and right coverage, and the guide block 4 can slide along the guide groove 8 to drive the water pump 2 to move in the front and back directions to achieve front and back coverage. The above movement operation is repeated according to the preset path until the entire bottom of the pool is completely cleaned.

[0041] By incorporating frame 1, water pump 2, and spray mechanism 3, the dredging operation of the water tank is optimized. It can operate continuously during the normal water circulation process of the water tank, efficiently sucking up the bottom sludge without draining the water, avoiding system downtime caused by traditional dredging, and significantly saving time and labor costs. At the same time, the device adopts a fully external control structure, allowing personnel to accurately cover the entire pool area through six-directional movement without entering the pool, completely eliminating safety hazards such as collapse, and providing outstanding safety benefits. In addition, combined with high-pressure spray mechanism 3, it can spray high-pressure water jets in a directional manner to quickly break up hard mud layers and simultaneously suck them up, meeting the dredging needs of complex sites.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
