Description

Technical Field

[0001] This utility model relates to the field of pumping equipment, and in particular to an assembled pumping equipment. Background Technology

[0002] In the current process of urban renovation and construction, as well as the construction of underground drainage networks, many complex and challenging practical situations arise. Conventional water pumps are often large and heavy, making them extremely inconvenient to transport and move. For example, when the pumping location needs to be changed frequently at the construction site, moving these bulky pumps requires a significant amount of manpower and resources, severely slowing down the construction progress. In some special construction scenarios, such as when the water level at the excavation point is low, conventional water pumps, due to their pumping mechanism and structural characteristics, are difficult to effectively pump water and cannot meet the actual pumping needs. This results in water accumulation during construction that cannot be drained in time, affecting the progress of subsequent operations. When encountering a small construction area, the placement of these large water pumps becomes a problem. They occupy a large amount of space, making it difficult to find a suitable placement location, and may even affect the normal operation of other construction activities. Utility Model Content

[0003] To improve the portability of pumping equipment, this application provides an assembled pumping equipment.

[0004] The assembled pumping equipment provided in this application adopts the following technical solution: An assembled water pumping device includes: a motor, a hose connector, a flexible shaft, and a vibrator. The hose connector is located at the output end of the motor, and the two ends of the flexible shaft are respectively connected to the output end of the motor and the vibrator. It also includes a water pump, which includes an eccentric bearing and an impeller. The eccentric bearing is connected to the shaft of the impeller, and the vibrator is detachably connected to the eccentric bearing.

[0005] By adopting the above technical solution, the flexible shaft connects the motor and the vibrator. The power output by the motor is effectively transmitted to the vibrator through the flexible shaft. The eccentric bearing in the vibrator and the impeller work together to realize the pumping function of the water pump. The detachable connection between the vibrator and the eccentric bearing facilitates the assembly, maintenance and replacement of parts of the equipment, and improves the flexibility and convenience of the equipment.

[0006] Optionally, the vibrator has an eccentric rotor, and the flexible shaft is connected to the eccentric rotor.

[0007] By adopting the above technical solution, an eccentric rotor is set inside the vibrator, and a flexible shaft is connected to the eccentric rotor. This allows the power output by the motor to be transmitted to the eccentric rotor through the flexible shaft, enabling eccentric movement inside the vibrator. This allows the eccentric bearing to drive the impeller to rotate, converting the power generated by vibration into an effective power to drive the impeller to rotate, thus promoting stable rotation of the impeller and achieving the pumping function.

[0008] Optionally, the eccentric bearing includes an eccentric shaft, one end of which is connected to the shaft of the impeller, and the other end is connected to the eccentric rotor.

[0009] By adopting the above technical solution, one end of the eccentric shaft is connected to the impeller shaft, and the other end is connected to the eccentric rotor. The power transmitted from the motor is transmitted to the impeller in sequence through the flexible shaft, the eccentric rotor, and the eccentric shaft, realizing the effective transmission of power. This allows the impeller to rotate stably for pumping operations and coordinates the power relationship between the vibrator and the impeller, ensuring that all parts of the pumping equipment work together and improving the overall stability and reliability of the equipment.

[0010] Optionally, the eccentric bearing includes a receiving space, the eccentric shaft is located within the receiving space, the eccentric shaft includes a main shaft and a secondary shaft, the main shaft is connected to the secondary shaft, the main shaft is connected to the rotating shaft of the impeller, and the secondary shaft rotates around the main shaft.

[0011] By adopting the above technical solution, the eccentric bearing is provided with a receiving space, the eccentric shaft is located in the receiving space and is divided into a main shaft and a secondary shaft. The main shaft is connected to the impeller shaft, and the secondary shaft rotates around the main shaft to realize the rotation of the main shaft, so that the impeller can rotate.

[0012] Optionally, the vibrator has a vibration space that communicates with the receiving space, the eccentric rotor is located in the vibration space and at least partially extends into the receiving space, the eccentric rotor abuts against the side wall of the secondary shaft, and the eccentric rotor circulates along the inner wall of the vibrator.

[0013] By adopting the above technical solution, the eccentric rotor circulates in a circular motion on the inner wall of the vibrator. The eccentric rotor extends into the receiving space. During the motion, the eccentric rotor continuously drives the secondary shaft to rotate around the main shaft, realizing the conversion of the eccentric rotor's power into the main shaft's power, so that the impeller can rotate continuously.

[0014] Optionally, the vibrator sidewall is threadedly connected to the eccentric bearing sidewall.

[0015] By adopting the above technical solution, the vibrator sidewall is connected to the threaded sidewall of the eccentric bearing, allowing for easy disconnection of the vibrator and eccentric bearing. The transmission engagement between the eccentric rotor and the secondary shaft ensures that no additional components need to be removed when separating the vibrator from the eccentric bearing. After removing the vibrator, a threaded plug can be installed on it, transforming the vibrator into a concrete compactor.

[0016] Optionally, the water pump includes a negative pressure space, an inlet, and an outlet. The impeller is located within the negative pressure space. Both the inlet and the outlet are connected to the negative pressure space. The outlet is located on the radial sidewall of the water pump.

[0017] By adopting the above technical solution, the impeller rotation generates negative pressure in the negative pressure space, allowing water to be smoothly drawn in from the inlet. The water forms a vortex in the negative pressure space and moves away from the axis under the action of centrifugal force, and is discharged from the outlet at the radial side wall of the water pump, thus realizing the water pumping function.

[0018] Optionally, the hose connector is provided with an anti-reverse device, which is connected to the output end of the motor.

[0019] By adopting the above technical solution, the anti-reverse device can prevent the motor from reversing and causing the flexible shaft and vibrator to reverse, reducing equipment failures, extending service life, and lowering maintenance and replacement costs. Simultaneously, it ensures that the flexible shaft and impeller rotate in the correct direction, maintaining a stable water flow within the pump and preventing problems such as pumping interruptions and turbulent flow caused by reverse rotation. This ensures continuous and efficient pumping operations, facilitates construction progress according to plan, and guarantees that construction quality meets standards.

[0020] In summary, this application includes at least one of the following beneficial effects: 1. The vibrator and eccentric bearing are connected by threads. The detachable design not only facilitates assembly, maintenance and component replacement, but also allows the vibrator to be converted into a concrete vibrator by removing the vibrator and installing a plug, achieving multiple uses and adapting to different construction scenarios.

[0021] 2. Through the orderly connection and cooperation of components such as flexible shaft, eccentric rotor, and eccentric shaft, a complete power transmission link from motor to impeller is constructed, which accurately converts the vibration power into impeller rotation power, ensuring stable impeller operation and achieving efficient water pumping.

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses an assembled water pumping device, referring to... Figures 1 to 3 The system includes a motor 1, with a flexible shaft 3 connected to the output end of the motor 1. A flexible hose 31 is fitted onto the flexible shaft 3, with a vibrator 4 and a hose connector 2 connected to both ends of the flexible shaft 3. The hose connector 2 is located at the output end of the motor 1. The vibrator 4 has a vibration space 401 inside, and an eccentric rotor 41 is installed inside the vibration space 401. One end of the flexible shaft 3 is connected to the eccentric rotor 41. When the motor 1 is started, the motor 1 drives the flexible shaft 3 to rotate, and the flexible shaft 3 transmits power to the eccentric rotor 41 inside the vibration space 401 of the vibrator 4. The eccentric rotor 41 circulates in a circular motion along the inner wall of the vibrator 4 within the vibration space 401. The combination of the flexible shaft 3 and the flexible hose 31 replaces the traditional rigid transmission components, significantly reducing the overall size and weight of the equipment. The flexibility of the flexible shaft 3, combined with the support of the flexible hose 31, allows the equipment to flexibly adapt to confined spaces such as narrow alleys and small working surfaces, facilitating transportation, movement, and precise placement. This solves the problem of poor portability caused by the bulkiness of conventional water pumps 5, and improves the adaptability to complex construction scenarios.

[0032] Reference Figure 3and 5 The vibrator 4 is connected to a water pump 5. The water pump 5 includes an eccentric bearing 51 and an impeller 52. The impeller 52 is disposed inside the water pump 5. The eccentric bearing 51 includes a receiving space 5101. An eccentric shaft 511 is disposed inside the receiving space 5101. One end of the eccentric shaft 511 is connected to the rotating shaft of the impeller 52, and the other end is fitted with an eccentric rotor 41. The eccentric shaft 511 includes a main shaft 5111 and a secondary shaft 5112. The main shaft 5111 and the secondary shaft 5112 are connected. The main shaft 5111 is connected to the impeller 52. The secondary shaft 5112 is parallel to the main shaft 5111 and is disposed close to the inner wall of the eccentric bearing 51. The secondary shaft 5112 can rotate around the main shaft 5111. The vibration space 401 is connected to the receiving space 5101. The eccentric rotor 41 extends at least partially into the receiving space 5101. When the eccentric rotor 41 moves in a circular motion along the inner wall of the vibrator 4, it will contact the secondary shaft 5112 and push the secondary shaft 5112 to move. The secondary shaft 5112 drives the main shaft 5111 to rotate, so that the impeller 52 of the water pump 5 can rotate continuously, allowing the impeller 52 to rotate stably for pumping operations.

[0033] In a preferred embodiment, refer to Figure 3 The vibrator 4 has threads on its inner wall, and the eccentric bearing 51 also has threads on its outer wall. The vibrator 4 and the eccentric bearing 51 are threaded together. The vibrator 4 and the eccentric bearing 51 can be easily separated. Since the eccentric rotor 41 is not directly connected to the secondary shaft 5112, but uses a rotational drive for transmission, it is not necessary to remove other parts when separating the vibrator 4 from the eccentric bearing 51. This simplifies the assembly of the equipment and makes it easier for workers to use on actual construction sites.

[0034] Preferably, refer to Figure 6 and 7 An additional plug 42 can be provided, with threads on its outer wall. After separating the vibrator 4 and the eccentric bearing 51, the threads on the inner wall of the vibrator 4 can be threadedly connected to the threads on the outer wall of the plug 42, thus sealing off the vibration space 401. At this time, the vibrator 4 becomes a concrete vibrator rod, which can be used for concrete vibration. The equipment is easy to assemble and disassemble, and the disassembled equipment can still be used for vibration, making it a multi-functional device that can adapt to different construction scenarios.

[0035] In a preferred embodiment, refer to Figure 4 and 5The water pump 5 includes a negative pressure space 501, an inlet 502, and an outlet 503. An impeller 52 is located within the negative pressure space 501. Both the inlet 502 and the outlet 503 are connected to the negative pressure space 501, and the outlet 503 is located on the radial sidewall of the water pump 5. The rotation of the impeller 52 generates negative pressure in the negative pressure space 501, allowing water to be smoothly drawn in from the inlet 502. The water forms a vortex within the negative pressure space 501 and moves away from the axis under centrifugal force, exiting through the outlet 503 on the radial sidewall of the water pump 5, thus achieving the pumping function.

[0036] In a preferred embodiment, an anti-reverse device is provided inside the hose connector 2, and the anti-reverse device is connected to the output end of the motor 1. The anti-reverse device can prevent the motor 1 from reversing and causing the flexible shaft 3 and vibrator to reverse, reducing equipment failures, extending service life, and lowering maintenance and replacement costs. At the same time, it ensures that the flexible shaft 3 rotates in the forward direction, and the impeller 52 also rotates in the forward direction, maintaining a stable water flow in the water pump 5, avoiding problems such as pumping interruption and water flow turbulence caused by the impeller 52 reversing, ensuring continuous and efficient pumping operations, helping construction to proceed as planned, and ensuring that construction quality meets standards.

[0037] The implementation principle of an assembled water pumping device according to an embodiment of this application is as follows: Connect one end of the flexible shaft 3 to the output end of the motor 1, insert it into the connector 2 of the flexible hose 31 and fix it, and connect the other end to the vibrator 4. Then connect both ends of the flexible hose 31 to the vibrator 4 and the connector 2 of the flexible hose 31. Finally, connect the vibrator 4 to the eccentric bearing 51 of the water pump 5 through threads to ensure that the eccentric rotor 41 extends into the receiving space 5101. After checking that the anti-reverse device inside the connector 2 of the flexible hose 31 is normal, place the water pump 5 in a suitable position so that the inlet 502 contacts the water to be pumped and the outlet 503 is connected to the drainage pipe. When the motor 1 is started, power is transmitted via the flexible shaft 3 to the eccentric rotor 41 inside the vibrator 4, causing it to circulate along the inner wall of the vibrator 4. This drives the secondary shaft 5112 of the eccentric shaft 511 to rotate around the main shaft 5111, which in turn drives the impeller 52 to rotate in the negative pressure space 501, generating negative pressure. Water is drawn in through the inlet 502 and discharged through the outlet 503 via eddy currents and centrifugal force, thus achieving water pumping. If it needs to be converted into a concrete vibrator, the threaded connection between the vibrator 4 and the eccentric bearing 51 can be unscrewed, and the threaded plug 42 can be screwed into the vibrator 4 to seal the vibration space 401.

[0038] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
