Comprising a submersible pump, a filter screen is fixedly arranged on one side of the submersible pump, a plurality of filter grooves are formed in the side wall of the filter screen, and a protection mechanism is arranged at the bottom of the submersible pump. After the lower side wall of the bottom plate is in contact with sludge at the bottom of a pool, the piston rod of the electric telescopic rod is controlled to contract through a remote control instruction, the linkage frame is driven to move towards the submersible pump body, and the movable block pushes the side plate to expand outwards around the hinged position of the side plate and the bottom through the connecting rod until the side plate is completely converted into a horizontal state from a vertical state; at the moment, the unfolded side plates and the bottom plate jointly form an expansion supporting platform, the pressure intensity of the submersible pump on pond bottom sludge is reduced by increasing the contact area, the sinking phenomenon of the submersible pump caused by motor vibration during water pumping operation is effectively restrained, and therefore the risk that the pond bottom sludge permeates into the submersible pump through a filter tank is greatly reduced; and the safety of the submersible pump working underwater is improved.

Description

Technical Field

[0001] This utility model relates to a submersible pump, specifically, to a pump body for safe underwater sewage discharge. Background Technology

[0002] A submersible pump is a fluid transport device specifically designed for deep-water environments, its core function being the lifting and transfer of water. The device consists of a pump body unit, a power motor, an inlet filter, and other key components, forming an integrated underwater working system. During operation, the entire system must be completely submerged below the surface of the liquid to be drained. The motor drives the impeller to generate centrifugal force, drawing water in through the inlet and transporting it through the pump body's piping. This fully submersible working principle effectively avoids cavitation, ensuring stable and efficient operation of the equipment in deep-water conditions.

[0003] When a submersible pump settles to the bottom of a pool with thick silt, direct contact between the pump body and the silt can cause operational hazards. During pumping operations, the vibration of the pump's motor can cause the equipment to sink continuously, allowing silt from the pool bottom to seep into the pump body through the filter structure. Existing technologies generally use a conical drag-increasing base plate combined with a steel mesh platform to increase the bottom contact area and enhance resistance to sinking. However, while this structure improves the stability of the submersible pump, it also brings significant space occupation problems. During the submersible pump's descent, the steel mesh platform can easily become entangled with aquatic plants such as weeds, which not only slows down the pump's descent speed but also affects the final settling depth, thereby reducing the pump's sewage extraction efficiency.

[0004] In addition, although the filter screen configured on the submersible pump can effectively intercept large particulate impurities during operation, it has a structural defect when the pump is stopped: fine particles from the outside can enter back through the filter screen pores during non-operation periods. These contaminants accumulate inside the pump body, which will cause progressive damage to the motor's operating accuracy and the protective performance of the sealing components, ultimately affecting the overall service life of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a pump body for safe underwater sewage discharge, so as to solve the problems mentioned in the background art above:

[0006] Existing technologies generally involve adding a conical drag-increasing base plate combined with a steel mesh platform to the bottom of the pump body to enhance its resistance to sinking by increasing the bottom contact area. However, during the submersible pump's sinking process, the steel mesh platform is prone to entanglement with aquatic plants such as water plants, which not only slows down the equipment's sinking speed but also easily affects the final sinking depth.

[0007] To address the above problems, the present invention aims to provide a pump body for safe underwater sewage discharge, including a submersible pump. A filter screen is fixedly installed on one side of the submersible pump, and the side wall of the filter screen has several filter grooves. A protective mechanism is provided at the bottom of the submersible pump. The protective mechanism includes a base plate fixedly installed on the lower side wall of the submersible pump. Two side plates are symmetrically hinged to both sides of the base plate. A baffle plate is fixedly installed on one side of each side plate. A flipping assembly is provided between the two side plates to drive the two side plates to rotate synchronously. When the flipping assembly drives the side plates to rotate to a horizontal state, the lower side of the side plate is on the same plane as the lower side wall of the base plate. When the flipping assembly drives the side plates to rotate to a vertical state, the two side plates are located on both sides of the submersible pump. At this time, the two baffle plates combine to form a dust baffle plate, which blocks the filter groove openings of the filter screen.

[0008] As a further improvement to this technical solution, the flipping assembly includes two movable blocks symmetrically arranged on both sides of the submersible pump. Two vertically arranged guide rods are slidably arranged at both ends of the movable blocks, and the lower ends of the guide rods are fixedly arranged on the upper side wall of the base plate.

[0009] As a further improvement to this technical solution, the flipping assembly also includes a connecting rod hinged to the side of the moving block away from the submersible pump, and the other end of the connecting rod is hinged to the side wall of the corresponding side plate.

[0010] As a further improvement to this technical solution, the flipping assembly also includes a linkage frame fixedly mounted on the upper side wall of the two moving blocks. An electric telescopic rod is fixedly installed on the upper side wall of the linkage frame. The piston rod end of the electric telescopic rod slides through the top of the linkage frame and is fixedly mounted on the upper side wall of the submersible pump.

[0011] As a further improvement to this technical solution, a stabilizing frame is fixed to the upper end of the two guide rods located on the same side of the submersible pump, and the stabilizing frame is fixedly installed on the upper side wall of the submersible pump.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The underwater safe sewage pump body, after contacting the bottom sludge on the lower side wall of the bottom plate, controls the piston rod of the electric telescopic rod to retract via remote control, driving the linkage frame to move towards the submersible pump body. This causes the moving block to push the side plate outward around its hinge with the bottom via the connecting rod until the side plate completely changes from a vertical state to a horizontal state. At this time, the unfolded side plate and the bottom plate together form an extended support platform. By increasing the contact area, the pressure of the submersible pump on the bottom sludge is reduced, effectively suppressing the sinking phenomenon caused by motor vibration during water pumping operations. This significantly reduces the risk of bottom sludge seeping into the submersible pump through the filter tank, improving the safety of the submersible pump when working underwater.

[0014] 2. When the tilting assembly rotates the side plate to a vertical position, the two baffles combine to form a dust baffle. The dust baffle blocks the filter screen opening, forming a physical barrier. When the submersible pump is not in operation, it can effectively prevent external impurities from entering the submersible pump through the filter screen, thereby avoiding abnormal equipment operation caused by foreign matter accumulation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 As shown, the purpose of this embodiment is to provide a pump body for safe underwater sewage discharge, including a submersible pump 1. The top of the submersible pump 1 is provided with a drain outlet. When in use, the entire pump is submerged to the bottom of the pool and a drain pipe is connected to the drain outlet. A filter screen 11 is fixedly installed on one side of the submersible pump 1. The side wall of the filter screen 11 has several filter grooves. During the operation of the submersible pump 1, water flows through the filter grooves into the submersible pump 1 and is then discharged outward through the drain pipe. During this process, the filter grooves can effectively intercept aquatic plants and other debris in the water, preventing such debris from entering the submersible pump 1 and causing equipment damage.

[0024] A protective mechanism 2 is installed at the bottom of the submersible pump 1. The protective mechanism 2 is used to prevent the entire device from sinking to the bottom sludge layer under its own weight. The structure of the protective mechanism 2 is described in detail below, referring to... Figure 3 The protective mechanism 2 includes a base plate 21 fixedly installed on the lower side wall of the submersible pump 1. Two side plates 22 are symmetrically hinged to both sides of the base plate 21. A flipping assembly is provided between the two side plates 22 to drive the two side plates 22 to rotate synchronously. The flipping assembly can switch between two working states:

[0025] When the submersible pump 1 is in operation, the tilting assembly drives the side plate 22 to rotate to a horizontal position. At this time, the lower side of the side plate 22 is on the same plane as the lower side wall of the bottom plate 21. When the lower side wall of the bottom plate 21 contacts the silt at the bottom of the pool, the two side plates 22 simultaneously contact the silt at the bottom of the pool. The side plates 22 and the bottom plate 21 together form an extended support surface. By increasing the contact area, the pressure of the submersible pump 1 on the silt is reduced, thereby effectively inhibiting the submersible pump 1 from sinking into the silt and reducing the probability of silt entering the interior of the submersible pump 1 through the filter tank.

[0026] When the submersible pump 1 is not in operation, the tilting assembly drives the side plate 22 to rotate to a vertical position. At this time, the two side plates 22 are close to the two sides of the submersible pump 1, reducing the space occupied by the submersible pump 1 and providing convenient conditions for the storage management and transportation of the submersible pump 1.

[0027] The following details the structure of the flip component, please refer to... Figure 3 The flipping assembly includes two movable blocks 25 symmetrically arranged on both sides of the submersible pump 1. Two vertically arranged guide rods 24 are slidably arranged at both ends of the movable blocks 25. The lower ends of the guide rods 24 are fixedly arranged on the upper side wall of the base plate 21. The upper ends of the two guide rods 24 located on the same side of the submersible pump 1 are fixed with a stabilizing frame 29. The stabilizing frame 29 is fixedly arranged on the upper side wall of the submersible pump 1. The stabilizing frame 29, together with the base plate 21, positions the two ends of the guide rods 24, keeping the guide rods 24 in a vertical state. The two guide rods 24 restrict the movable blocks 25 to move vertically only along the axis of the guide rods 24.

[0028] The flipping assembly also includes a connecting rod 26 hinged to the side of the moving block 25 away from the submersible pump 1. The other end of the connecting rod 26 is hinged to the side wall of the corresponding side plate 22. The flipping assembly also includes a linkage frame 27 fixedly installed on the upper side wall of the two moving blocks 25. The linkage frame 27 has an n-shaped structure. An electric telescopic rod 28 is fixedly installed on the upper side wall of the linkage frame 27. The electric telescopic rod 28 is waterproof and has a built-in battery and wireless control module. The battery powers the electric telescopic rod 28. The operator can remotely control the extension and retraction of the piston rod of the electric telescopic rod 28 through a remote control. The end of the piston rod of the electric telescopic rod 28 slides through the top of the linkage frame 27 and is fixedly installed on the upper side wall of the submersible pump 1.

[0029] When the piston rod of the electric telescopic rod 28 extends, the distance between the electric telescopic rod 28 and the submersible pump 1 increases, and the main body of the electric telescopic rod 28 moves away from the submersible pump 1. The moving main body of the electric telescopic rod 28 drives the linkage frame 27 to move upward, causing the linkage frame 27 to drive the two moving blocks 25 to move upward synchronously. The moving blocks 25 drive one end of the connecting rod 26 to move, causing the other end of the connecting rod 26 to drive the corresponding side plate 22 to rotate towards the submersible pump 1. When the piston rod of the electric telescopic rod 28 is fully extended, the side plate 22 rotates to a vertical state, causing the submersible pump 1 to enter a non-working state. When the piston rod of the electric telescopic rod 28 retracts, the electric telescopic rod 28 drives the linkage frame 27 to move closer to the submersible pump 1, and the moving blocks 25 drive the side plate 22 to rotate away from the submersible pump 1 through the connecting rod 26. When the side plate 22 rotates to a horizontal state, the submersible pump 1 enters a working state.

[0030] Meanwhile, a baffle plate 23 is fixedly installed on one side of the side plate 22. When the flipping component drives the side plate 22 to rotate to a vertical state, the side walls of the two baffle plates 23 come into contact with each other. At this time, the two baffle plates 23 combine to form a dust baffle. The dust baffle blocks the filter groove opening of the filter screen 11, forming a physical barrier. When the submersible pump 1 is not in operation, it can effectively prevent external impurities from entering the interior of the submersible pump 1 through the filter groove, thereby avoiding abnormal equipment operation caused by foreign matter deposition.

[0031] Reference Figure 2 The base plate 21 is fixedly installed at the bottom of the submersible pump 1 by several bolts. When it is necessary to clean the sludge adhering to the protective mechanism 2, the operator can disassemble the above bolts in sequence to form an adjustable gap between the base plate 21 and the submersible pump 1. By appropriately increasing the gap space, it is convenient for workers to clean the sludge between the base plate 21 and the submersible pump 1, thereby avoiding the impact of sludge residue on the cleanliness level of the submersible pump 1.

[0032] During use, the operator must first submersible pump 1, which is not in operation, sink to the bottom of the pool. At this stage, the vertical side plate 22, due to its retracted shape, can effectively avoid obstruction by aquatic plants and debris. After the lower side wall of the bottom plate 21 contacts the silt at the bottom of the pool, the piston rod of the electric telescopic rod 28 is retracted by remote control, driving the linkage frame 27 to move towards the body of the submersible pump 1. During this mechanical transmission process, the moving block 25 pushes the side plate 22 outward around the hinge point between it and the bottom plate 21 via the connecting rod 26 until the side plate 22 completely changes from a vertical state to a horizontal state. At this time, the retracted side plate 22 and the bottom plate 21 together form an extended support platform. By increasing the contact area, the pressure of the submersible pump 1 on the silt at the bottom of the pool is reduced, effectively suppressing the sinking phenomenon caused by motor vibration during the pumping operation of the submersible pump 1, thereby greatly reducing the risk of silt at the bottom of the pool seeping into the interior of the submersible pump 1 through the filter tank. Example

[0033] When this device is used for sewage suction in riverbeds with abundant aquatic plants and hard bottoms, the operator can activate the electric telescopic rod 28 to retract its piston rod. At this time, the linkage frame 27 moves closer to the submersible pump 1 along with the electric telescopic rod 28. The linkage frame 27 synchronously pulls the moving block 25 to drive the two side plates 22 to expand outward around the axis through the connecting rod 26. When the piston rod of the electric telescopic rod 28 is fully retracted, the two side plates 22 will be in a downward tilting working posture. By sinking this device to the bottom of the pool and ensuring that the bottom edge of the side plates 22 contacts the pool bed, the working height of the submersible pump 1 can be effectively raised. This structural design can avoid the risk of dense aquatic plants clogging the filter screen 11 and maintain the stable operating efficiency of the submersible pump 1 under complex working conditions.
