Description

Technical Field

[0001] This invention relates to the field of pumps, and more particularly to a floating pump. Background Art

[0002] Floating pumps are a commonly used type of pump. Patent publication CN2144649942U discloses a floating pump in which a battery pack powers the pumping motor. However, in this design, the battery pack is located on one side (right or left) of the pumping motor during operation. Since the pumping motor generates significant vibrations during operation, this structure, which places the battery pack on one side of the pumping motor, is highly likely to cause the entire pump to overturn when the pumping motor is running.

[0003] Patent publication CN216714736U discloses a floating pump in which the battery is also located on the side of the pumping motor, so this floating pump also has a high probability of tipping over during operation. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a floating pump.

[0005] The technical solution adopted in this invention is as follows:

[0006] A floating pump includes a pumping motor, a housing, and an impeller. The pumping motor is disposed inside the housing, and the impeller is mounted on the shaft of the pumping motor. The pump also includes a control motherboard and a lithium battery. The control motherboard is connected to the pumping motor, and the lithium battery is clipped and fixed inside the housing. The lithium battery and the control motherboard are connected via a plug-in joint. A partition is provided inside the housing, dividing the space inside the housing into a first compartment and a second compartment. The lithium battery is located in the first compartment, and the pumping motor is located in the second compartment. The first compartment is a sealed compartment. A filter hole is provided on the shell wall of the housing, and the filter hole is located in the second compartment. When the floating pump floats on the water surface, the lithium battery is positioned above the pumping motor.

[0007] In this type of floating pump, by placing the lithium battery above the pumping motor inside the casing, compared to a design where the battery is placed next to the pumping motor, the stability of the pumping motor's operation can be significantly improved, and the probability of the floating pump overturning during pumping motor operation can be reduced.

[0008] In this design, a lithium battery is used to power the pump motor. Furthermore, a ternary lithium battery is chosen instead of a lithium iron phosphate battery, giving it a relatively lightweight advantage. This allows for improved pumping capacity while maintaining a lighter overall pump weight. Additionally, the lithium battery is connected to the control board via a plug-in connection, allowing for easy recharging of the battery as needed.

[0009] This design uses a pumping motor at the bottom to pump water, while the lithium battery provides power at the top. The entire floating pump is positioned with its lower part below the water surface and its upper part above the water surface. Therefore, the probability of water leakage above the floating pump is relatively low, which greatly improves the safety factor of the lithium battery.

[0010] In this design, the pumping motor drives the impeller to rotate, and when the impeller rotates, water enters the housing through the filter holes on the housing.

[0011] Optionally, it also includes a protective cover, which is disposed inside the housing. The protective cover and the partition are fitted together to form an inner cavity, and the pumping motor is disposed inside the inner cavity, with the shaft of the pumping motor located outside the inner cavity.

[0012] Specifically, the impeller is installed on the shaft of the pump motor. The main body of the pump motor is located inside the inner cavity, while the impeller is located outside the inner cavity. The inner cavity is formed by the partition and the protective cover to provide good protection for the pump motor and prevent the electrical components inside the pump motor from being submerged in water.

[0013] Optionally, the housing includes a body and a cover, the partition is disposed in the body, the water filter hole is disposed on the body, the cover is detachably fitted together with the body, and a sealing component is provided between the cover and the body.

[0014] Specifically, the main body and the cover are fitted together, and a sealing component is used to seal between the cover and the main body to prevent water leakage. In this solution, one end of the cover is rotatably connected to the main body via a hinge, and the cover and one side of the main body are fitted together by a snap fastener. The waterproof rating between the cover and the main body reaches IPX8.

[0015] Optionally, an inner shell plate is provided inside the main body, the inner shell plate is located in the first cavity, the inner shell plate, the partition plate and the shell cover form a sealed cavity, the control motherboard and the lithium battery are both located in the sealed cavity, there is a gap between the main body and the inner shell plate, a vibration motor is installed on the main body, and the vibration motor is electrically connected to the control motherboard.

[0016] In this design, an inner shell plate is further installed within the main body. This inner shell plate, along with partitions and a cover, forms a sealed cavity where the control board and lithium battery are housed. A vibration motor is then installed on the main body. The purpose of the vibration motor is to periodically activate when needed, causing the main body to vibrate at regular intervals (e.g., every 10 minutes). This dislodges snails (and other planktonic organisms) attached to the outer wall of the main body. Snails attached to the main body not only cause the float pump to sink but can also clog the filter holes. Therefore, the vibration motor prevents snail attachment through periodic vibration. Simultaneously, since vibration can affect the stability of the lithium battery and control board, the inner shell plate is further installed to mount the lithium battery and control board, reducing the impact of vibration on these components.

[0017] In this design, the switch of the vibration motor is controlled by the vibration mainboard.

[0018] Optionally, the outer wall of the body is provided with a recess, and some of the water filter holes are located within the recess.

[0019] The pump features a concave section. During operation, the upper end of the concave section is above the water surface, while the lower end is below. The same filter hole on the concave section is also partially above and partially below the water surface. Due to the concavity formed on the surface of the pump, when water at the surface enters the pump body through the filter hole on the concave section, gas will be present in the water flow, causing air bubbles to be mixed in with the water flow generated by the impeller. The air bubbles in the water flow can flush the pipes inside the pump, preventing debris (such as duckweed and algae) from accumulating in the pipes.

[0020] In this design, the concave portion and the filter holes allow air bubbles to be mixed into the water flow generated by the pump motor. These air bubbles increase the flushing effect of the water flow on the pump's internal pipes, reducing the probability of water accumulating in the pump's internal pipes. Furthermore, the periodic vibration of the vibrating motor generates more air bubbles in the water flowing through the filter holes in the concave portion. The vibration of the motor itself causes vibration in the pump's internal pipes. This vibration, combined with the effect of air bubbles in the water flow, further enhances the flushing ability of the air-bubbly water flow on the pipes, improving the cleaning effect of the water flow on the pipes.

[0021] Optionally, it also includes an end cover, which is disposed inside the housing and located in the second compartment. The end cover is provided with an inlet and an outlet. The impeller is located inside the end cover. The inner wall of the end cover is provided with a toothed column, which is located at the inlet.

[0022] Sharp-toothed columns are installed at the water inlet of the end cover because there is a certain probability that plastic film will be mixed in with the water during the process of the impeller drawing water into the end cover. Small plastic films may block the end cover or pipelines. Therefore, sharp-toothed columns are installed near the water inlet of the end cover and distributed around the water inlet. When water is drawn into the end cover by the impeller, the plastic film in the water will rotate in the end cover due to the rotation of the impeller. When the plastic film encounters the sharp-toothed columns, large pieces of plastic film will be torn into smaller pieces, reducing the probability of pipeline blockage.

[0023] Optionally, the housing is dumbbell-shaped, and the filter holes are provided on the side walls and bottom of the housing, and the filter holes are strip-shaped.

[0024] Specifically, the filter holes are strip-shaped, with a width of 1-3mm and a length of 10-15cm. The filter holes of these dimensions can ensure that leaves and branches in the water cannot enter the body through the filter holes, and aquatic organisms such as fish and shrimp cannot enter the body either.

[0025] Meanwhile, because the casing is dumbbell-shaped, with a structure that is wide at both ends and narrow in the middle, it can improve the stability of the pump when it floats on the water surface, allowing the entire pump to float in the water like a jellyfish.

[0026] Optionally, a handle ring is provided on the outside of the housing, and a flat surface is provided on the housing, with the handle located on one side of the flat surface.

[0027] The flat surface is designed to facilitate the installation of photovoltaic panels on the flat surface of the casing when needed, so that the photovoltaic panels can be used to charge the lithium battery.

[0028] The purpose of the handle is to facilitate the loading and unloading of the entire pump. A switch button is also located on the handle, which is electrically connected to the control board.

[0029] The beneficial effects of this invention are: by placing the lithium battery above the pumping motor, the stability of the pumping motor operation is improved, and the probability of the floating pump overturning during pumping motor operation is reduced. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a floating pump includes a pumping motor, a housing, and an impeller 16. The pumping motor is disposed inside the housing, and the impeller 16 is mounted on the shaft of the pumping motor. It also includes a control motherboard 9 and a lithium battery 12. The control motherboard 9 is connected to the pumping motor, and the lithium battery 12 is clipped and fixed inside the housing. The lithium battery 12 and the control motherboard 9 are connected by a plug-in joint. A partition 10 is provided inside the housing, which divides the space inside the housing into a first compartment and a second compartment. The lithium battery 12 is located in the first compartment, and the pumping motor is located in the second compartment. The first compartment is a sealed compartment. The housing wall is provided with a filter hole 202, and the filter hole 202 is located in the second compartment. When the floating pump floats on the water surface, the lithium battery 12 is located above the pumping motor.

[0038] In this type of floating pump, by placing the lithium battery 12 above the pumping motor inside the housing, compared to a solution where the battery is placed next to the pumping motor, placing the lithium battery 12 above the pumping motor can significantly improve the stability of the pumping motor's operation and reduce the probability of the floating pump overturning when the pumping motor is working.

[0039] In this design, two lithium batteries (12 in total) are used to power the pumping motors. The lithium batteries (12 in total) are ternary lithium batteries (12 in total) instead of lithium iron phosphate batteries (12 in total), giving them a relatively lighter weight. This allows for improved pumping capacity while maintaining a relatively light overall pump weight. Furthermore, the lithium batteries (12 in total) are connected to the control motherboard (9 in total) via a plug-in connection, allowing for easy recharging of the lithium batteries (12 in total) as needed.

[0040] This design uses a pumping motor at the bottom to pump water, while the lithium battery 12 provides power from the top. The entire floating pump is positioned with its lower part below the water surface and its upper part above the water surface. Therefore, the probability of water leakage above the floating pump is relatively low, which greatly improves the safety factor of the lithium battery 12.

[0041] In this design, the pumping motor drives the impeller 16 to rotate, and when the impeller 16 rotates, water enters the housing through the filter hole 202 on the housing.

[0042] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, it also includes a protective cover 14, which is disposed inside the housing. The protective cover 14 and the partition 10 are fitted together to form an inner cavity. The water pump motor is disposed inside the inner cavity, and the shaft of the water pump motor is located outside the inner cavity.

[0043] Specifically, an impeller 16 is installed on the shaft of the pumping motor. The main body of the pumping motor is located inside the inner cavity, while the impeller 16 is located outside the inner cavity. The inner cavity is formed by the partition 10 and the protective cover 14 to provide good protection for the pumping motor and prevent water immersion accidents of the electrical components inside the pumping motor.

[0044] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the housing includes a body 2 and a cover 4. A partition 10 is disposed inside the body 2, and a water filter hole 202 is disposed on the body 2. The cover 4 is detachably fitted together with the body 2, and a sealing component is provided between the cover 4 and the body 2.

[0045] Specifically, the main body 2 and the cover 4 are fitted together, and the cover 4 and the main body 2 are sealed by a sealing component to prevent water leakage between the cover 4 and the main body 2. In this solution, one end of the cover 4 is rotatably connected to the main body 2 by a hinge 3, and the cover 4 and one side of the main body 2 are fitted together by a fastener 6. The waterproof rating between the cover 4 and the main body 2 reaches IPX8.

[0046] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, an inner shell plate 8 is provided inside the main body 2. The inner shell plate 8 is located in the first cavity. The inner shell plate 8, the partition plate 10 and the shell cover 4 form a sealed cavity. The control main board 9 and the lithium battery 12 are both located in the sealed cavity. There is a gap between the main body 2 and the inner shell plate 8. A vibration motor 7 is installed on the main body 2. The vibration motor 7 is electrically connected to the control main board 9.

[0047] In this design, an inner shell plate 8 is further installed inside the main body 2. The inner shell plate 8, the partition plate 10, and the shell cover 4 form a sealed cavity, in which the control main board 9 and the lithium battery 12 are placed. Then, a vibration motor 7 is installed on the main body 2. The function of the vibration motor 7 is to be activated periodically when needed, so that the main body 2 vibrates at regular intervals (e.g., every 10 minutes). This can shake off snails (and other planktonic organisms) attached to the outer wall of the main body 2. Snails attached to the main body 2 can not only cause the float pump to sink, but may also block the filter holes 202. Therefore, the vibration motor 7 is installed to prevent snails from attaching by periodically vibrating the main body 2. At the same time, since vibration can affect the stability of the lithium battery 12 and the control main board 9, the inner shell plate 8 is further installed to mount the lithium battery 12 and the control main board 9, thereby reducing the impact of vibration on the lithium battery 12 and the control main board 9.

[0048] In this design, the switch of the vibration motor 7 is controlled by the vibration mainboard.

[0049] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a recessed portion 201 is provided on the outer wall of the main body 2, and some of the water filter holes 202 are located inside the recessed portion 201.

[0050] The concave portion 201 is provided. When in use, the upper end of the concave portion 201 is located above the water surface, while the lower end of the concave portion 201 is located below the water surface. The same filter hole 202 on the concave portion 201 is also partially located above the water surface and partially located below the water surface. Due to the concavity formed by the concave portion 201 on the surface of the main body 2, when water at the water surface enters the main body 2 through the filter hole 202 on the concave portion 201, there will be gas in the water flow, which will cause the water flow formed by the impeller 16 to be mixed with air bubbles. The air bubbles in the water flow can flush the pipe 13 inside the pump and prevent debris (such as duckweed and water net algae) in the water from accumulating in the pipe 13.

[0051] In this design, the concave portion 201 and the filter hole 202 allow air bubbles to be mixed in the water flow generated by the pump motor. These air bubbles can increase the flushing effect of the water flow on the pump pipe 13 and reduce the probability of water accumulating in the pump pipe 13. At the same time, in this design, the periodic vibration of the vibrating motor 7 can generate more air bubbles in the water passing through the filter hole 202 on the concave portion 201. Also, the vibration of the vibrating motor 7 will cause the body 2 to vibrate, which will cause the pump pipe 13 to vibrate to a certain extent. The vibration of the pump pipe itself and the effect of air bubbles in the water flow can further enhance the flushing ability of the air bubble water flow on the pipe and improve the cleaning effect of the water flow on the pipe.

[0052] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, it also includes an end cover 15, which is disposed inside the housing and located in the second compartment. The end cover 15 is provided with an inlet 1501 and an outlet 1502. The impeller 16 is located inside the end cover 15. A toothed column is provided on the inner wall of the end cover 15, and the toothed column is located at the inlet 1501.

[0053] A toothed column is installed at the water inlet 1501 of the end cover 15 because during the process of the impeller 16 drawing water into the end cover 15, there is a certain probability that the water contains plastic film. Small plastic films may block the end cover 15 or the pipe 13. Therefore, a toothed column is installed near the water inlet 1501 of the end cover 15, and the toothed column is distributed around the water inlet 1501. When water is drawn into the end cover 15 by the impeller 16, the plastic film in the water will rotate in the end cover 15 due to the rotation of the impeller 16. When the plastic film encounters the toothed column, large pieces of plastic film will be torn into small pieces, reducing the probability of the pipe 13 being blocked.

[0054] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the shell is dumbbell-shaped, and filter holes 202 are provided on the side walls and bottom of the shell, and the filter holes 202 are strip-shaped.

[0055] Specifically, the filter hole 202 is strip-shaped, with a width of 1-3mm and a length of 10-15cm. The filter hole 202 of the above dimensions can ensure that leaves and branches in the water cannot enter the body 2 through the filter hole 202, and fish, shrimp and other organisms in the water cannot enter the body 2.

[0056] Meanwhile, because the casing is dumbbell-shaped, with a structure that is wide at both ends and narrow in the middle, it can improve the stability of the pump when it floats on the water surface, allowing the entire pump to float in the water like a jellyfish.

[0057] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a handle 1 ring is provided on the outside of the housing, and a flat surface 401 is provided on the housing, with the handle 1 located on one side of the flat surface 401.

[0058] The flat surface 401 is provided to facilitate the installation of photovoltaic panels on the flat surface 401 of the housing when needed, so that the photovoltaic panels can be used to charge the lithium battery 12.

[0059] The purpose of setting up handle 1 is to facilitate the lifting and placing of the entire pump. At the same time, a switch button 5 is set on handle 1, which is electrically connected to the control main board 9.

[0060] Example 2

[0061] The difference between this embodiment and embodiment 1 is that this embodiment further provides a photovoltaic panel on the flat surface 401, and then the photovoltaic panel is connected to the lithium battery.

[0062] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent modifications made based on the content of the present invention specification, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
