Description

Technical Field

[0001] This utility model relates to the field of fluid machinery technology, specifically a water pump with a small pump body structure. Background Technology

[0002] In modern industrial production, daily life, and various engineering projects, water pumps play a crucial role as fluid transport equipment. From the transportation of chemical raw materials in industrial fields and oil-water separation in oil extraction, to water supply and drainage systems in the construction industry, to agricultural irrigation and aquarium circulation in homes, the efficient operation of water pumps is indispensable. Water pumps belong to the category of fluid machinery. As an important type of mechanical equipment, fluid machinery's core function is to achieve "fluid energy transfer" or "mechanical energy-fluid energy conversion" through the interaction between mechanical structures and fluids, and its applications are even more extensive.

[0003] Chinese Patent Publication No. CN222596319U discloses a water pump, including a main body with a pump body inside; a floating body is provided at the upper end of the main body, allowing the entire water pump to float on the water surface; the floating body has a chamber where a battery is placed, supplying power to the pump body; the pump body includes a motor and an impeller, and a liquid-drawing seat is provided at the lower end of the main body, having an inlet and a outlet; the motor drives the impeller to rotate within the liquid-drawing seat, and liquid enters the liquid-drawing seat through the inlet and exits through the outlet. This utility model provides a water pump that can float on water.

[0004] In existing technologies, the basic water conveyance process of a water pump is only described as "liquid entering from the inlet and exiting from the outlet," without designing any position adjustment structure related to the water conveyance pipeline. In actual use, if the floating position on the water surface shifts or the location of the water conveyance target (such as the inlet of a reservoir or the irrigation area) changes, the water pump cannot adjust the orientation and horizontal position of the outlet / water conveyance pipeline. It can only change the water conveyance direction by pushing the entire floating body with external force, which is cumbersome and has low precision. Therefore, we have made an improvement and proposed a water pump with a small pump body structure. Utility Model Content

It can be flexibly adapted to the "change of water delivery target position" in the installation environment to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A small-volume water pump includes a base, a pump body fixedly mounted on the top of the base, and bellows pipes fixedly mounted on opposite sides of the pump body. Water delivery pipes are fixedly mounted at the ends of the two bellows pipes that are far apart from each other. The pump body, the two bellows pipes, and the water delivery pipes are connected.

[0012] As a preferred technical solution of this application, each of the two fixing plates is provided with two fixing bolts on its top, and the fixing bolts are inserted into the interior of the fixing plate and threadedly connected thereto. Each of the two sliding plates is provided with several through slots that cooperate with the fixing bolts.

[0013] As a preferred technical solution of this application, side rings are provided on the outer sides of the long rod and the short rod and on the corresponding sides of the fixed plate. The side rings are fixedly connected to the long rod and the short rod, and are slidably connected to the fixed plate. Z-shaped sliders are provided on the top of the two fixed plates. The Z-shaped sliders are inserted into the interior of the fixed plates and are slidably connected to them. Several insert rods are fixedly installed on the side of the two Z-shaped sliders that are close to each other. Several grooves that cooperate with the insert rods are provided on the long rod and the short rod. Several return springs are provided between the adjacent fixed plates and the Z-shaped sliders, and the two ends of the several return springs are fixedly connected to the fixed plates and the Z-shaped sliders respectively.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a small-volume water pump, including a base 1, a pump body 2 fixedly installed on the top of the base 1, bellows pipes 3 fixedly installed on corresponding sides of the pump body 2, water supply pipes 4 fixedly installed at the ends of the two bellows pipes 3 that are far apart from each other, the pump body 2, the two bellows pipes 3 and the water supply pipes 4 are connected, a long rod 5 and a short rod 6 are fixedly installed at the bottom of the two water supply pipes 4 respectively, a fixing plate 7 is fixedly installed on the outer side of the long rod 5 and the short rod 6, a connecting plate 9 is provided on both sides of the base 1, and the two connecting plates 9 are inserted into the interior of the base 1 and slidably connected thereto, a sliding plate 8 is fixedly installed on the side of the two connecting plates 9 that are far apart from each other, the two sliding plates 8 are respectively inserted into the interior of the two fixing plates 7 and slidably connected thereto, two rotatable gears 10 are rotatably connected inside the base 1, and two teeth are fixedly installed on the side of the two connecting plates 9 that are close to each other, and the teeth mesh with the rotatable gears 10.

[0032] In this embodiment of the invention, the water pump is a G501 pump body. When the pump body is working, it first uses the base 1 as a stable foundation. After the pump body 2 on top is started, it generates power to drive the water flow. The water flow starts from the pump body 2 and enters the two bellows pipes 3 connected to it. The bellows pipes 3 use their own expansion and contraction characteristics to buffer the pressure fluctuations generated by the water flow during transmission, avoiding water flow impact from damaging the pipeline. After being buffered, the water flow continues to flow into the water delivery pipeline 4 connected to the bellows pipes 3, and is finally delivered to the designated area through the water delivery pipeline 4 to complete the water delivery operation.

[0033] When the position of the water supply pipeline 4 needs to be adjusted according to the installation space or water supply requirements, the steering gear 10 inside the base 1 is driven to rotate by external force. Since the teeth on the steering gear 10 and the connecting plate 9 mesh with each other, the rotation of the steering gear 10 will cause the two connecting plates 9 to slide horizontally inside the base 1. The sliding directions of the two connecting plates 9 are opposite, one slides towards the center of the base, and the other slides away from the center of the base 1. While the connecting plates 9 are sliding, the sliding plate 8 fixedly connected to it will slide inside the fixed plate 7, thereby pushing the fixed plate 7 and the long rod 5, short rod 6 and the water supply pipeline 4 connected to the fixed plate 7 to adjust their positions until the water supply pipeline 4 reaches the appropriate working position.

[0034] In this embodiment of the utility model, the overall design is small in size and the layout of each component is reasonable. The base 1, pump body 2, bellows pipe 3 and water supply pipe 4 are closely connected, without occupying too much space. It can be easily installed in small-size installation scenarios, such as small equipment cooling systems, mini water treatment devices, etc., thus broadening the application range of the water pump.

[0035] By cooperating with the steering gear 10, connecting plate 9, sliding plate 8 and fixing plate 7, the position of the water supply pipeline 4 can be adjusted. The placement of the water supply pipeline 4 can be flexibly adjusted according to the actual installation environment and changes in the target position of water supply, without having to disassemble and reinstall the entire water pump. This reduces the difficulty of installation and debugging and improves the adaptability of the water pump to different usage scenarios.

[0036] The installation of the bellows pipe 3 can effectively buffer water pressure fluctuations, reduce the impact of water flow on the pipeline, avoid pipeline vibration or damage caused by unstable water flow, ensure the stability of water flow during transmission, and improve water delivery efficiency.

[0037] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of the present invention, a second bevel gear 12 is fixedly installed on the side of the two steering gears 10 that are close to each other. A first bevel gear 11 is rotatably connected inside the base 1, and the first bevel gear 11 meshes with the two second bevel gears 12. A handle is fixedly installed on one side of the first bevel gear 11, and the handle passes through one side of the base 1 and is rotatably connected to it. A sealing ring is embedded on the base 1 at the junction of the base 1 and the handle.

[0038] Limiting rods 13 are fixedly installed on the top and bottom of the two connecting plates 9, and several limiting rods 13 are inserted into the base 1 and slidably connected to it.

[0039] Two fixing bolts 14 are provided on the top of each of the two fixing plates 7, and the fixing bolts 14 are inserted into the interior of the fixing plate 7 and threadedly connected to it. Several through slots that cooperate with the fixing bolts 14 are provided on each of the two sliding plates 8.

[0040] Side rings 17 are provided on the outer sides of the long rod 5 and the short rod 6, on the corresponding sides of the fixed plate 7. The side rings 17 are fixedly connected to the long rod 5 and the short rod 6, and are slidably connected to the fixed plate 7. Z-shaped sliders 19 are provided on the top of the two fixed plates 7, and the Z-shaped sliders 19 are inserted into the interior of the fixed plate 7 and slidably connected to it. Several insert rods 18 are fixedly installed on the side of the two Z-shaped sliders 19 that are close to each other. Several grooves that cooperate with the insert rods 18 are provided on the long rod 5 and the short rod 6. Several return springs are provided between the adjacent fixed plates 7 and the Z-shaped sliders 19, and the two ends of the several return springs are fixedly connected to the fixed plates 7 and the Z-shaped sliders 19 respectively.

[0041] The inner walls of the two water supply pipes 4 are each inlaid with an airbag ring 15. The top of the two water supply pipes 4 is fixedly installed with a pump 16. The two pumps 16 pass through the top of the water supply pipes 4 and are fixedly connected to them. The output end pipe of the pump 16 is fixedly connected to the airbag ring 15. The airbag ring 15 is provided with an air inlet hole that matches the output end pipe of the pump 16. The base 1 is fixedly installed with a control module 20. The control module 20 is electrically connected to the pump body 2 and the two pumps 16. Flanges are fixedly installed on the side of the two water supply pipes 4 that are far apart from each other.

[0042] In this embodiment of the invention, to facilitate the driving of the steering gear 10, a second bevel gear 12 is fixedly installed on the side of each steering gear 10 that is close to each other. Simultaneously, a first bevel gear 11 is rotatably connected inside the base 1, and the first bevel gear 11 meshes with the two second bevel gears 12. When the position of the water supply pipe 4 needs to be adjusted, the operator rotates a handle located on one side of the first bevel gear 11, which passes through one side of the base 1 and is rotatably connected to the base 1. The handle drives the first bevel gear 11 to rotate inside the base 1. Since the first bevel gear 11 meshes with the two second bevel gears 12, the rotation of the first bevel gear 11 synchronously drives the two second bevel gears 12 to rotate, thereby driving the steering gear 10, which is fixedly connected to the second bevel gear 12, to rotate. Subsequently, through the meshing transmission of the teeth of the steering gear 10 and the connecting plate 9, the sliding of the connecting plate 9 and the position adjustment of the water supply pipe 4 are achieved.

[0043] Meanwhile, a sealing ring is embedded on the base 1 at the junction of the base 1 and the handle. The sealing ring fits tightly against the contact surface between the base 1 and the handle, which can effectively prevent external dust, moisture and other impurities from entering the interior of the base 1, avoid impurities from causing wear to the first bevel gear 11, the second bevel gear 12 and other transmission components, and ensure the normal operation of the transmission system.

[0044] Limiting rods 13 are fixedly installed at the top and bottom of both connecting plates 9, and several limiting rods 13 are inserted into the interior of the base 1 and slidably connected to the base 1. When the connecting plate 9 slides along the interior of the base 1 under the drive of the steering gear 10, the connecting plate 9 will drive the limiting rods 13 to slide synchronously inside the base 1. Due to the sliding connection structure between the limiting rods 13 and the base 1, the sliding direction of the connecting plate 9 can be restricted, preventing the connecting plate 9 from shifting up or down or tilting during the sliding process, and ensuring that the connecting plate 9 always slides stably in the horizontal direction.

[0045] Meanwhile, the limiting rod 13 can also limit the sliding stroke of the connecting plate 9. When the connecting plate 9 slides to the maximum stroke position of the limiting rod 13, the limiting rod 13 will contact the limiting structure inside the base 1 to prevent the connecting plate 9 from continuing to slide, thus avoiding the connecting plate 9 from disengaging from the teeth of the steering gear 10 due to excessive sliding and ensuring the stability of the transmission system.

[0046] After the water supply pipe 4 is adjusted to a suitable position using components such as the connecting plate 9 and the sliding plate 8, two fixing bolts 14 are installed on the top of each fixing plate 7 to fix the relative position of the fixing plate 7 and the sliding plate 8. The fixing bolts 14 are inserted into the interior of the fixing plate 7 and threadedly connected to it. The operator rotates the fixing bolts 14 so that the bottom of the fixing bolts 14 passes through the fixing plate 7 and is inserted into the through groove on the sliding plate 8 that mates with the fixing bolts 14. Since the through groove matches the size of the fixing bolts 14, the insertion of the fixing bolts 14 into the through groove restricts the sliding plate 8 from sliding inside the fixing plate 7, thereby fixing the relative position of the fixing plate 7 and the sliding plate 8 and ensuring that the water supply pipe 4 is stably maintained in the adjusted position.

[0047] If the position of the water supply pipe 4 needs to be adjusted again, simply rotate the fixing bolt 14 in the opposite direction so that the bottom of the fixing bolt 14 comes out of the through groove of the slide plate 8, thereby releasing the restriction on the slide plate 8. Then the position of the water supply pipe 4 can be adjusted again by driving the steering gear 10.

[0048] To further improve the stability of the connection between the long rod 5, the short rod 6, and the fixed plate 7, side rings 17 are provided on the outer sides of the long rod 5 and the short rod 6, on corresponding sides of the fixed plate 7. The side rings 17 are fixedly connected to the long rod 5 and the short rod 6, and are also slidably connected to the fixed plate 7. When the long rod 5 or the short rod 6 slides inside the fixed plate 7, the side rings 17 slide synchronously with the long rod 5 and the short rod 6. The side rings 17 can limit the sliding direction of the long rod 5 and the short rod 6, preventing radial displacement, and also reducing the direct friction between the long rod 5 and the short rod 6 and the fixed plate 7, thus reducing component wear.

[0049] In addition, Z-shaped sliders 19 are provided on the top of both fixed plates 7. The Z-shaped sliders 19 are inserted into the interior of the fixed plates 7 and slidably connected to them. Several insert rods 18 are fixedly installed on the side of the two Z-shaped sliders 19 that are close to each other. Several grooves that mate with the insert rods 18 are provided on the long rods 5 and the short rods 6. Several return springs are provided between the adjacent fixed plates 7 and the Z-shaped sliders 19. The two ends of the return springs are fixedly connected to the fixed plates 7 and the Z-shaped sliders 19, respectively. In the natural state, the return springs are in the extended state, which pushes the Z-shaped sliders 19 to slide closer to the long rods 5 and the short rods 6, so that the insert rods 18 are inserted into the grooves of the long rods 5 and the short rods 6, thereby fixing the relative position of the long rods 5 and the short rods 6 with the fixed plates 7 and preventing the long rods 5 and the short rods 6 from sliding inside the fixed plates 7.

[0050] When it is necessary to adjust the position of the long rod 5 and short rod 6 inside the fixed plate 7, the operator pulls the Z-shaped slider 19 away from the long rod 5 and short rod 6. The Z-shaped slider 19 compresses the return spring and drives the insertion rod 18 out of the groove of the long rod 5 and short rod 6, releasing the restriction on the long rod 5 and short rod 6. At this time, the long rod 5 and short rod 6 can be pushed to slide to the appropriate position inside the fixed plate 7. After the adjustment is completed, the Z-shaped slider 19 is released. The return spring pushes the Z-shaped slider 19 back to its original position under the action of elasticity, so that the insertion rod 18 is inserted back into the corresponding groove, completing the fixation of the long rod 5 and short rod 6 to the fixed plate 7.

[0051] To accommodate external water pipes of different diameters, airbag rings 15 are embedded in the inner walls of both water supply pipes 4. Pumps 16 are fixedly installed at the top of both water supply pipes 4, passing through the top of the pipes and fixedly connected to them. The output pipe of the pump 16 is fixedly connected to the airbag ring 15, and the airbag ring 15 has an air inlet hole that mates with the output pipe of the pump 16. A control module 20 is fixedly installed inside the base 1, electrically connected to the pump body 2 and the two pumps 16. An external controller is electrically connected to the control module 20.

[0052] When connecting external water pipes of different diameters, the operator sends a command to the control module 20 via the external controller. The control module 20 then controls the corresponding pump 16 to start according to the command. After the pump 16 starts, it inflates the airbag ring 15 through the output pipe. The airbag ring 15 expands under the gas pressure until the inner wall of the airbag ring 15 is tightly fitted with the outer wall of the external water pipe, thus achieving a sealed connection between the water supply pipeline 4 and the external water pipe. If it is necessary to disassemble the external water pipe or adjust the size of the airbag ring 15, the control module 20 controls the pump 16 to work in reverse, extracting the gas from the airbag ring 15. The airbag ring 15 then contracts, releasing the fixation to the different water pipes.

[0053] Meanwhile, the control module 20 can also control the working status of the pump body 2. The operator sends start / stop or speed adjustment commands to the control module 20 through an external controller. The control module 20 controls the pump body 2 to start, stop, or adjust the speed according to the commands, thereby controlling the start / stop and flow rate of the water pump. In addition, flanges are fixedly installed on the sides of the two water pipelines 4 that are far apart from each other. The flanges can be used to fix the water pipelines 4 to other equipment or pipelines, improving the stability of the connection.

[0054] In this embodiment of the utility model, by turning the lever and cooperating with the first bevel gear 11 and the second bevel gear 12, the operator only needs to turn the lever to realize the synchronous rotation of the two steering gears 10, without having to operate the two steering gears 10 separately, which simplifies the adjustment steps, reduces the difficulty of operation, and improves the adjustment efficiency of the water supply pipeline 4 position.

[0055] The sealing ring effectively prevents external impurities from entering the base 1, avoiding malfunctions in the transmission components due to wear caused by impurities, reducing maintenance frequency, extending the overall service life of the water pump, and lowering operating costs.

[0056] The setting of the limit rod 13 can limit the sliding direction of the connecting plate 9, prevent it from deviating or tilting during the sliding process, ensure that the teeth of the connecting plate 9 and the steering gear 10 always maintain a good meshing state, avoid transmission failure caused by poor meshing, and improve the reliability of the transmission system.

[0057] By limiting the sliding stroke of the connecting plate 9, it is possible to prevent the connecting plate 9 from disengaging from the steering gear 10 due to excessive sliding. At the same time, it can also prevent the connecting plate 9 from colliding and being damaged with other internal components of the base 1, thus protecting the safety of the internal components of the water pump and further extending the service life of the water pump.

[0058] By using the fixing bolt 14 and the through groove of the slide plate 8, the relative positions of the fixing plate 7 and the slide plate 8 can be firmly fixed, preventing the slide plate 8 from sliding due to vibration and other factors during the operation of the water pump, thereby ensuring the stability of the water pipeline 4 and ensuring the normal operation of the water supply.

[0059] The detachable design of the fixing bolt 14 makes it easier to make secondary adjustments to the position of the water supply pipeline 4 without damaging the fixing plate 7 or the sliding plate 8, reducing adjustment costs and improving the flexibility of the water pump.

[0060] The cooperation between the side ring 17, the insert rod 18, and the groove forms a double fixation and limiting of the long rod 5 and the short rod 6. It can not only limit the radial displacement of the long rod 5 and the short rod 6, but also fix their axial position, effectively preventing the long rod 5 and the short rod 6 from loosening or sliding during the operation of the water pump, thus ensuring the stability of the support structure of the water pipeline 4.

[0061] The side ring 17 reduces the direct friction between the long rod 5, the short rod 6 and the fixing plate 7, thus reducing the wear of the components. At the same time, the spring-driven fixing method of the insertion rod 18 avoids the component damage that may be caused by the use of a rigid fixing structure, further extending the service life of the relevant components.

[0062] The restriction on the long rod 5 and the short rod 6 can be released by pulling the Z-shaped slider 19. The adjustment process does not require complicated tools, making the operation simple and convenient, reducing the workload of operators and improving the adjustment efficiency.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
