Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a water pump thrust device. Background Technology

[0002] A water pump is a mechanical device that transports or pressurizes liquids. It is typically driven by an electric motor, using the rotation of components such as an impeller to draw in and pressurize water or other liquids, then deliver them to where they are needed. Water pumps are widely used in many fields, such as agricultural irrigation, urban water supply, and industrial production. Patent publication number CN216589243U discloses a reliable thrust device for a submersible pump, including a connecting plate and a buffer mechanism. The connecting plate is fitted to the pump shaft surface, and the buffer mechanism is detachably connected to the upper surface of the connecting plate. Multiple buffer mechanisms are included, each consisting of a limiting sleeve, a damping buffer spring, a buffer plate, and a pressure rod. The damping buffer spring is fixedly connected inside the limiting sleeve, the buffer plate is fixedly connected to the top of the damping buffer spring, and the pressure rod is slidably connected inside the limiting sleeve. This device effectively buffers pressure when it is too high, preventing wear on the thrust shaft, and also effectively prevents corrosion, extending service life and protecting the submersible pump.

[0003] The existing technical solutions mentioned above have the following drawbacks: When the water pump is in use, the water pump will move axially during operation. When axial movement occurs, the thrust assembly and the buffer assembly can effectively prevent the coupling from moving. However, when the coupling moves, the buffer distance of the buffer assembly is too short, which will cause the coupling to be unable to buffer and directly contact the thrust assembly, resulting in damage to the coupling. This causes inconvenience to the use of the water pump and increases the operating cost of the water pump. Utility Model Content

This solves the problem that when a water pump is in use, axial movement occurs during operation. While the thrust assembly and buffer assembly can effectively prevent the coupling from moving, if the buffer distance of the buffer assembly is too short, the coupling will not be able to buffer and will directly contact the thrust assembly, causing damage to the coupling. This inconveniences the use of the water pump and increases its operating costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump thrust device, comprising a pump shaft body, a coupling provided on the surface of the pump shaft body, a fixed plate fixedly installed on the top of the coupling, a thrust assembly provided on the top of the fixed plate, a fixed block fixedly installed on the top of the fixed plate, a limit slider fixedly connected to the outer side of the inner wall of the fixed block, the number of the limit sliders being several and the number of limit sliders being equally distributed, the number of the fixed blocks being several and the number of fixed blocks being equally distributed, the fixed block being provided with a moving buffer mechanism, and a reset moving mechanism being provided on the inner side of the moving buffer mechanism;

[0006] The movable buffer mechanism is used to provide movable buffering for the coupling.

[0007] The reset and moving mechanism is used to move and reset the moving buffer mechanism.

[0008] As a preferred embodiment of this utility model, the movable buffer mechanism includes a buffer block and a movable frame. The bottom of the buffer block is fixedly connected to the top of the movable frame. A sliding groove is provided on the outer side of the movable frame. A connecting block is fixedly connected to the left side of the inner side of the movable frame. A movable column is fixedly connected inside the connecting block. A fixing plate is fixedly connected to the inner side of the bottom of the movable frame.

[0009] In a preferred embodiment of this utility model, the reset and moving mechanism includes a second moving frame and a second fixed plate. The front side of the bottom of the second moving frame is fixedly connected to the rear side of the second fixed plate. A second sliding groove is provided on the outer side of the second moving frame. A reset spring is fixedly connected to the top of the second fixed plate. The top of the reset spring is fixedly connected to the bottom of the first fixed plate. A second connecting block is fixedly connected to the right side of the inner side of the second moving frame. A second movable column is fixedly connected inside the second connecting block. A swing block is provided on the front side of the second moving frame. Movable grooves are provided on the left and right sides of the swing block. The outer sides of the first movable column and the second movable column extend into the interior of the movable grooves. A connecting column is movably connected inside the swing block. The inner side of the connecting column is movably connected to the rear side of the inner wall of the fixed block.

[0010] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the outer side of both the first movable column and the second movable column, and the limiting plate is located on the rear side of the first movable frame.

[0011] As a preferred embodiment of this invention, a rubber pad is fixedly installed on the surface of the buffer block, the top of the rubber pad is in contact with the bottom of the thrust assembly, and the rubber pad is located on the top of the fixed block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves the advantage of easy buffering when the coupling moves axially. The coupling drives the fixed disc to move upward, which in turn drives the fixed block to move upward. As the fixed block moves upward, it causes the buffer block to contact the thrust assembly, which in turn causes the buffer block to move downward. This downward movement of the buffer block, along with the movement of the first movable frame, the first movable column, the first connecting block, and the first fixed plate, causes the swing block to swing upward. The swing block then drives the second connecting block, the second movable column, the second movable frame, and the second fixed plate to move upward. The second fixed plate causes the return spring to press upward. Under the restoring force of the return spring, the second fixed plate, the second connecting block, the second movable frame, the second movable column, the swing block, the first movable column, the first connecting block, the first fixed plate, the first movable frame, and the buffer block to reset. The reset of the buffer block returns the coupling to its original position. This design, through the coordinated use of the moving buffer mechanism and the reset moving mechanism, effectively buffers and prevents thrust on the coupling, reducing the operating cost of the water pump.

[0016] 2. By setting a moving buffer mechanism, this utility model can buffer the movement of the coupling, avoiding direct contact between the coupling and the thrust assembly, which would otherwise damage the coupling and improve its durability. Attached Figure Description

[0029] As a technical optimization of this utility model, by setting a reset moving mechanism 8, the moving buffer mechanism 7 can be moved and buffered, avoiding the situation where the moving buffer mechanism 7 cannot be reset during use, thus facilitating the movement of the buffer mechanism 7 and improving the ease of use of the moving buffer mechanism 7.

[0031] As a technical optimization of this utility model, by setting the limiting plate 9, the movable column 75 and the movable column 86 can be limited, which avoids the movable column 75 and the movable column 86 from deviating during use, thus playing a limiting role and improving the stability of the movable column 75 and the movable column 86.

The rear side of the fixed seat 12 is fixedly connected to the rear side of the inner wall of the fixed block 5. The fixed seat 12 is located on the rear side of the swing block 87.

[0037] As a technical optimization of this utility model, by setting the fixing seat 12, the contact area of ​​the connecting column 89 can be increased, avoiding the shaking of the connecting column 89, thereby increasing the contact area and improving the stability of the connecting column 89.

[0038] The working principle and usage process of this utility model are as follows: During use, when the coupling 2 moves axially, the coupling 2 drives the fixed plate 3 to move upward, the fixed plate 3 drives the fixed block 5 to move upward, and the fixed block 5 moves upward, causing the buffer block 71 to contact the thrust assembly 4. The buffer block 71 then moves downward, causing the moving frame 72, the movable column 75, the connecting block 74, and the fixed plate 76 to move downward, which in turn causes the swing block 87 to swing upward. The swing block 87 then drives the connecting block 85, the movable column 86, the moving frame 81, and the fixed plate 82 to move upward. The fixed plate 82 causes the return spring 84 to press upward. Under the action of the return spring 84, the fixed plate 82, the connecting block 85, the moving frame 81, the movable column 86, the swing block 87, the movable column 75, the connecting block 74, the fixed plate 76, the moving frame 72, and the buffer block 71 to reset. The reset of the buffer block 71 causes the coupling 2 to return to its original position, thus providing the advantage of easy buffering.

[0039] In summary, this water pump thrust device, through the coordinated use of the pump shaft body 1, coupling 2, fixed plate 3, thrust assembly 4, fixed block 5, limit slider 6, moving buffer mechanism 7, and reset moving mechanism 8, solves the problem that when the water pump is in use, axial movement may occur. When axial movement occurs, the thrust assembly and buffer assembly can effectively prevent the coupling from moving. However, if the buffer distance of the buffer assembly is too short when the coupling moves, the coupling will not be able to buffer and will directly contact the thrust assembly, causing damage to the coupling, inconvenience to the use of the water pump, and thus increasing the operating cost of the water pump.
