Description

Technical fields:

[0001] This utility model belongs to the technical field of submersible pumps, and specifically refers to a portable submersible pump. Background technology:

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. Therefore, submersible pumps are widely used in domestic water supply, mine rescue, industrial cooling, farmland irrigation, seawater lifting, and ship ballast adjustment. When a submersible pump is working, the motor drives the impeller to rotate. The high-speed rotation of the impeller, under the action of centrifugal force, throws the liquid outwards.

[0003] For example, Chinese utility model patent CN222558793U discloses a submersible pump with a floating mechanism, including a main body module and a detection module. The main body module includes a float plate, airbags installed on both sides of the float plate, a bracket fixed to the top of the float plate, a roller rotatably installed on the bracket, a drive component installed on the top of the float plate, a hanging rope with one end fixed to the drive component and the other end passing over the roller and downward through the float plate, a submersible pump body fixed to the end of the hanging rope, a filter component installed at the bottom of the submersible pump body, and a counterweight fixed at the bottom of the filter component. The float plate is made of a low-density material so that the float plate can float on the water surface. The airbags are fixed on both sides of the float plate to increase the buoyancy of the float plate, thereby ensuring the stability of the float plate. A through hole is opened in the middle of the float plate. The diameter of the through hole is larger than the diameter of the submersible pump body, so that the submersible pump body can be moved out through the through hole.

[0004] The aforementioned submersible pump is large in size and inconvenient to transport, and needs to be improved. Summary of the Invention:

[0005] The purpose of this invention is to provide a portable submersible pump to solve the technical problems mentioned in the background section.

[0006] This utility model is implemented as follows:

[0007] A portable submersible pump includes a support module and a pump body that is slidably and vertically connected to the support module. A buoyancy module is horizontally slidably connected to the support module. The buoyancy modules are located on opposite sides of the pump body's axis. The two buoyancy modules on both sides move towards each other to a retracted position to support the pump body. The two buoyancy modules on both sides move away from each other to an extended position to avoid the movement path of the pump body. The buoyancy modules support the support module in the water.

[0008] By adopting the above technical solution, when the submersible pump is not in operation, both the buoyancy module and the pump body are located within the support module. After the submersible pump is placed in the water, the buoyancy module unfolds and floats above the water surface to support the support module. The pump body then sinks underwater and begins operation. The buoyancy module and pump body unfold during operation and retract into the support module when not in operation, which helps reduce the volume occupied by the submersible pump during transportation, making it easier to carry and transport.

[0009] Preferably, the buoyancy module includes a first float plate slidably connected to the support module and a second float plate hinged to the first float plate. The first float plate and the second float plate can be rotated, folded, or unfolded, and the hinge axis of the second float plate is horizontal.

[0010] By adopting the above technical solution, the first and second float plates are folded and inserted into the support module, and float on the water surface after being unfolded. This helps to increase the horizontal projection area of ​​the float plates during operation and improves stability during operation.

[0011] Preferably, when the first float and the second float are deployed, the hinge axis of the first float and the second float is located below the first float.

[0012] By adopting the above technical solution and placing the hinge shaft at the bottom, it is beneficial that after the first and second floating plates are deployed and floated, the included angle between them will stably approach 180 degrees, thereby maximizing the horizontal projected area.

[0013] Preferably, the support module is provided with a filter screen, and the filter screen and the support module are spliced ​​together to form a sinking space, which is for the pump body to sink into, and the filter screen is used to cover the water inlet of the pump body.

[0014] By adopting the above technical solution, the buoyancy module unfolds, and after the submersible pump enters the water and starts working, the pump body sinks into the sinking space, and the filter screen covers the pump body inlet, which helps to reduce impurities entering the inlet. When the pump body is maintained or repaired, the pump body is moved upward into the support template, which allows the filter screen and impurities at the filter screen to quickly leave the pump body inlet, making it easy to quickly expose the inlet during pump maintenance or repair.

[0015] Preferably, the filter screen has a plurality of filter openings, and the filter screen undergoes elastic deformation when subjected to pressure.

[0016] By adopting the above technical solution, when the pump body's inlet is located in a shallow water area, the filter opening is small, reducing the entry of fine impurities in the shallow water area. At this time, the pump body's water intake speed is small. When it is necessary to increase the pump's water intake speed, the pump body sinks into the water, causing the filter screen's opening to open under pressure, thereby increasing the pump's water intake speed.

[0017] Preferably, the pump body is provided with a pull rope, and a rope reel is rotatably connected to the support module. The pull rope passes through the support module and is wound around the rope reel. The support module is provided with a drive motor, and the drive motor controls the rotation of the rope reel.

[0018] By adopting the above technical solution, when the pump body is submerged in water, if too many impurities accumulate near the filter screen and affect the inlet flow rate, the drive motor controls the reel to rotate back and forth, thereby causing the pump body to float and sink in the water, and the filter screen to shake under the elastic action to keep the impurities away from the vicinity of the pump body outlet.

[0019] Preferably, the pump body has a limiting hole, and the support module is provided with a telescopic rod, which passes through the limiting hole to limit the pump body.

[0020] By adopting the above technical solution, it is beneficial to maintain the stability of the submersible pump during operation.

[0021] Preferably, the telescopic rod includes a fixed section and a telescopic section, the telescopic section slides into or out of the fixed section, and the end of the telescopic section is provided with a magnetic ring, the magnetic ring being used to attract the pump body.

[0022] By adopting the above technical solution, when the pump body is located inside the support module, the telescopic section is located inside the fixed section, and the magnetic ring is located below the pump body, as the pump body sinks, the pump body moves closer to the magnetic ring. After the magnetic ring attracts the pump body, the telescopic section follows the pump body and extends out of the fixed section. When the pump body re-enters the support module, the pump body drives the telescopic section to extend into the fixed section. When the telescopic section of the pump body is fully extended into the fixed section, the end of the fixed section presses against the magnetic ring, causing the magnetic ring to detach from the pump body.

[0023] The outstanding advantages of this utility model compared to the prior art are:

[0024] 1. When the submersible pump of this utility model is working, the buoyancy module extends out of the support module, and when it is not working on the table, it retracts into the support module, which helps to reduce the volume occupied by the submersible pump during transportation, making it easier to carry and transport.

[0025] 2. The first and second float plates of this utility model are folded and inserted into the support module. After unfolding, they float on the water surface, which helps to increase the horizontal projection area of ​​the float plates during operation and improves the stability during operation.

[0026] 3. By placing the hinge shaft at the bottom, this utility model facilitates the first and second floating plates to float up, and their included angle stabilizes to close to 180 degrees, thereby maximizing the horizontal projected area. Attached image description:

[0032] The present invention will be further described below with reference to specific embodiments:

[0033] This application discloses a portable submersible pump, see [link to implementation details]. Figure 1 and Figure 2 The system includes a support module 1 and a pump body 2. The support module 1 includes a handle 11 and a support part 12. The handle 11 is located above the support part 12 and is fixedly connected to the support part 12. The operator can lift the support module 1 using the handle 11. A sinking groove 121 is provided on the support part 12, which penetrates the section of the support part 12 away from the handle 11, allowing the pump body 2 to sink into the water. A filter screen 3 is fixed at the lower end of the support part 12. The filter screen 3 is arranged around the outer periphery of the sink trough 121. Several filter ports 31 are opened on the filter screen 3. The filter screen 3 can undergo elastic deformation when it is pressed and return to its shape after the pressure is released. The filter ports 31 deform as the filter screen 3 deforms. The filter screen 3 is located in the moving path of the pump body 2. When the pump body 2 moves downward and enters the filter screen 3, the filter screen 3 supports the pump body 2 and covers the water inlet of the pump body 2, filtering impurities and reducing the amount of impurities in the water entering the water inlet of the pump body 2, which may cause damage to the submersible pump.

[0034] The filter screen 3 and the support part 12 are joined to form a sunken space 32, which is located below the sinking trough 121 and is connected to the sinking trough 121. The pump body 2 moves between the sunken space 32 and the sinking trough 121.

[0035] See Figure 1 and Figure 2 The upper end of the support part 12 is rotatably connected to a rope reel 4, which is located below the handle part 11. The rotation axis of the rope reel 4 is horizontal. A pull rope 21 is fixed on the pump body 2. The pull rope 21 passes through the support part 12 and is wound on the rope reel 4. A drive motor 122 is installed on the support part 12. The drive motor 122 is used to drive the rope reel 4 to rotate to unwind or rewind the pull rope 21, thereby driving the pump body 2 to float or sink through the pull rope 21.

[0036] Two buoyancy modules 5 are slidably connected to the support part 12. The two buoyancy modules 5 are located on opposite sides of the axis of the pump body 2 and are distributed horizontally. The sliding direction of the two buoyancy modules 5 is parallel to the distribution direction. The support part 12 is provided with sliding channels 125. The position and number of sliding channels 125 correspond one-to-one with the position and number of buoyancy modules 5. The sliding channels 125 are located on opposite sides of the sinking tank 121 and are connected to the sinking tank 121. The buoyancy modules 5 are slidably connected to the corresponding sliding channels 125. When the two buoyancy modules 5 slide towards each other into the retracted position, they enter the sinking tank 121 to support the pump body 2. When the two buoyancy modules 5 slide away from each other into the extended position, they disengage from the sinking tank 121 to avoid the movement path of the pump body 2. At this time, the buoyancy modules 5 are used to float in the water to support the support part 12.

[0037] See Figure 1 and Figure 2 The buoyancy module 5 includes a first float 51 and a second float 52, which are hinged together. The hinge axis between the first float 51 and the second float 52 is horizontal, and the hinge axis of the first float 51 and the second float 52 is perpendicular to the distribution direction of the buoyancy module 5. The first float 51 and the second float 52 can be rotated and then folded or unfolded. When the buoyancy module 5 is in the unfolded position, the first float 51 and the second float 52 are unfolded, and the distribution direction of the first float 51 and the second float 52 is parallel to the distribution direction of the sliding channel 125. The second float 52 is located outside the first float 51, and the hinge axis between the first float 51 and the second float 52 is located below the first float 51 and the second float 52. When the buoyancy module 5 is in the retracted position, the first float 51 and the second float 52 are folded, and the second float 52 is located below the first float 51. The first float 51 and the second float 52 support the pump body 2.

[0038] See Figure 2 and Figure 3Each first float 51 has limit blocks 123 fixed on both opposite sides. The distribution direction of the limit blocks 123 on the same first float 51 is horizontal and perpendicular to the sliding direction of the first float 51. Limit grooves 124 are formed on the inner wall of the sliding channel 125. The position and number of limit grooves 124 correspond one-to-one with the position and number of limit blocks 123. The limit blocks 123 slide in the corresponding limit grooves 124, and the inner wall of the sliding channel 125 is in contact with the first float 51. When the first float 51 and the second float 52 are deployed, the first float 51 is connected to the support part 12 through the limit blocks 123.

[0039] See Figure 2 and Figure 4 At least two telescopic rods 6 are installed on the support part 12. Both telescopic rods 6 are located in the sinkhole 121. The two telescopic rods 6 are distributed in the horizontal direction, and the telescopic direction of the two telescopic rods 6 is vertical. Limiting holes 22 are opened on the pump body 2. The position and number of limiting holes 22 correspond one-to-one with the position and number of telescopic rods 6. The telescopic rods 6 pass through the corresponding limiting holes 22 to limit the pump body 2. The telescopic rod 6 includes a fixed section 61 and a telescopic section 62. The axes of the telescopic section 62 and the fixed section 61 are coaxial. The fixed section 61 is fixedly connected to the support part 12. The telescopic section 62 slides into or out of the fixed section 61. The outer peripheral wall of the fixed section 61 is in contact with the inner wall of the limiting hole 22. The end of the telescopic section 62 away from the fixed section 61 is the end. A magnetic ring 63 is fixed to the end of the telescopic section 62. The magnetic ring 63 is arranged around the outer periphery of the telescopic section 62. The outer diameter of the magnetic ring 63 is larger than that of the fixed section 61. A convex ring 64 is formed at the end of the magnetic ring 63 near the fixed section 61. The outer diameter of the convex ring 64 is the same as that of the fixed section 61. The magnetic ring 63 is used to adsorb the pump body 2. When the magnetic ring 63 is in contact with the lower end face of the pump body 2, the convex ring 64 is inserted into the limiting hole 22, and the outer ring surface of the convex ring 64 is in contact with the inner wall of the limiting hole 22.

[0040] A damping element exists between the telescopic section 62 and the fixed section 61, and the telescopic section 62 and the fixed section 61 are positioned by damping. In this embodiment, the damping element is an elastic damping pad.

[0041] See Figure 2 During the operation of the submersible pump, the first float 51 and the second float 52 unfold and float on the water surface, while the pump body 2 sinks into the sinking space 32. The filter screen 3 and the pull rope 21 together support the pump body 2. When it is necessary to adjust the depth of the pump body 2 in the water or increase the water inlet speed, the drive motor 122 drives the rope reel 4 to unwind the pull rope 21. During the descent of the pump body 2, the deformation of the filter screen 3 increases, and the filter opening 31 on the filter screen 3 becomes larger, increasing the speed at which water enters the pump body 2's inlet.

[0042] As the pump body 2 operates for longer, debris accumulates on the filter screen 3 near the water inlet of the pump body 2. The drive motor 122 drives the windlass 4 to rotate back and forth, causing the pump body 2 to shake up and down in the water. The deformation of the filter screen 3 shakes off the nearby debris, making the filter screen 3 less prone to clogging.

[0043] See Figure 1 When the submersible pump is being displayed or transported, the first float 51 and the second float 52 stack and move into the sinking trough 121. The pump body 2 is located inside the sinking trough 121 and above the first float 51 and the second float 52, which support the pump body 2. This helps reduce the volume occupied by the submersible pump in non-working states such as transportation or display, and improves the portability of the submersible pump.

[0044] The implementation principle of this application embodiment is as follows: by setting a foldable first float 51 and a second float 52, the first float 51 and the second float 52 are unfolded when working, and folded up when not working, which helps to reduce the volume occupied by the submersible pump when not working, thereby improving the portability of the submersible pump.

[0045] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made to the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
