Description

TECHNICAL FIELD

[0001] The present application relates to an integrated dual-mode water pump, which is mainly used in a sanitation vehicle, and can effectively drive a low-pressure pump unit and a high-pressure pump unit independently or synchronously under the premise of one power source and stable operation. BACKGROUND

[0002] In actual use, the water truck and the washing and sweeping truck in the sanitation vehicle often need to be used for complex road conditions, so the low-pressure water system and the high-pressure water system need to be configured at the same time, and the low-pressure water system and the high-pressure water system need to be configured with corresponding power sources for independent driving. The setting of the low-pressure water system and the high-pressure water system and the configuration of the two power sources not only have relatively high manufacturing and maintenance costs of the equipment, but also significantly increase the space occupation.

[0003] In order to reduce the cost and the space occupation, an integrated dual-mode water pump directly driven by one power source is developed and used. The existing integrated dual-mode water pump for sanitation vehicles generally includes an independent low-pressure water pump and a high-pressure water pump, a single driving motor is used to drive a transmission assembly with two output ends, and a clutch is used to transmit the input ends of the low-pressure water pump and the high-pressure water pump to the output ends of the transmission assembly. In this way, the high and low pressure water pumps can be independently or synchronously driven by controlling the disconnection or combination of the clutch. Although this effectively reduces a set of power source, the independent setting of the low-pressure water pump, the high-pressure water pump and the transmission assembly still has relatively large overall space occupation. If the pump wheel of the low-pressure water pump, the plunger pump cylinder of the high-pressure water pump and the transmission assembly are integrated into the same housing, the space occupation can be effectively reduced, but the vibration generated during operation will have a relatively large influence on each other, thereby affecting the operation stability of the integrated dual-mode water pump.

[0004] Therefore, under the premise of driving by one power source, it is the research purpose of the present application to design an integrated dual-mode water pump which can effectively integrate the low-pressure water pump and the high-pressure water pump into one, thereby effectively reducing the space occupation, and effectively maintaining the operation stability of the low-pressure water pump and the high-pressure water pump after integration. SUMMARY

[0005] In view of the technical problems existing in the prior art, the present application provides an integrated dual-mode water pump which can effectively solve the technical problems existing in the prior art.

[0006] The technical scheme of the present application is:

[0007] An integrated dual-mode water pump, comprising:

[0008] The housing includes a transmission mechanism mounting cavity, a low-pressure pump mounting cavity, and a plunger pump mounting cavity.

[0009] The transmission mechanism includes a gear transmission assembly installed in the mounting cavity of the transmission mechanism, and the output end of the gear transmission assembly is connected to an external power source.

[0010] A low-pressure pump unit includes a pump wheel that is rotatably mounted in the low-pressure pump mounting cavity via a corresponding drive shaft, the drive shaft being connected to the first power output shaft of the gear transmission assembly via a first clutch;

[0011] A plunger pump unit includes a plunger pump cylinder body installed in the plunger pump mounting cavity, wherein the drive shaft of the plunger pump cylinder body is connected to the second power output shaft of the gear transmission assembly via a second clutch;

[0012] A pump body vibration damping assembly includes a vibration damping cavity on the housing. A first clutch and a second clutch are respectively disposed within the vibration damping cavity. The pump body vibration damping assembly includes a vibration absorber connected to the outer wall of the transmission mechanism mounting cavity and located within the vibration damping cavity. Annular vibration absorbing elements are fixedly connected to both sides of the vibration absorber and sleeved around the drive shaft and transmission shaft, respectively. When the first clutch is engaged, the annular vibration absorbing elements sleeved around the drive shaft retract onto the drive shaft. When the second clutch is engaged, the annular vibration absorbing elements sleeved around the transmission shaft retract onto the transmission shaft.

[0013] The vibration absorber includes a vibration absorbing shell, and the annular vibration absorbing element includes an inner elastic steel plate and an outer elastic steel plate arranged at intervals. The inner elastic steel plate and the outer elastic steel plate are respectively arranged in an arc shape and their bottom ends are respectively fixed to the bottom of both sides of the vibration absorbing shell. Corresponding damping materials are filled between the inner elastic steel plate and the outer elastic steel plate and inside the vibration absorbing shell. The upper parts of both ends of the vibration absorbing shell are respectively provided with driving elements that can tighten the inner elastic steel plate and the outer elastic steel plate.

[0014] The inner elastic steel plate is composed of two arc-shaped steel plates arranged side by side. Corresponding abutment rollers are rotatably installed on the arc-shaped steel plates at intervals. The driving component includes a first electromagnet for tightening the outer elastic steel plate and a set of second electromagnets for tightening the two arc-shaped steel plates respectively.

[0015] When the first clutch is engaged, the outer elastic steel plate sleeved around the drive shaft is tightened to the periphery of the drive shaft under the attraction drive of the first electromagnet. A set of second electromagnets are alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, so that the abutting rollers on the different arc-shaped steel plates roll and abut against the drive shaft respectively. When the second clutch is engaged, the outer elastic steel plate sleeved around the transmission shaft is tightened to the periphery of the transmission shaft under the attraction drive of the first electromagnet. A set of second electromagnets are alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, so that the abutting rollers on the different arc-shaped steel plates roll and abut against the transmission shaft respectively.

[0016] The arc-shaped steel plate is fixed with a housing for mounting the abutting roller at a position corresponding to the abutting roller. The ends of the abutting rollers extend through to the outside of the housing. The housing is provided with corresponding oil injection holes.

[0017] The output speed of the first power output shaft is lower than the output speed of the second power output shaft.

[0018] The ports of the transmission mechanism mounting cavity, the low-pressure pump mounting cavity, the plunger pump mounting cavity, and the vibration damping cavity are each fixedly fitted with a corresponding sealing end cap.

[0019] The low-pressure pump mounting cavity is provided with a corresponding low-pressure water outlet, and the sealing end cover installed on the low-pressure pump mounting cavity is provided with a corresponding low-pressure water inlet.

[0020] The sealing end cap installed on the piston pump mounting cavity is provided with a high-pressure water inlet and a high-pressure water outlet.

[0021] Both the first clutch and the second clutch are wet multi-plate clutches.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0023] 1) In addition to the transmission mechanism mounting cavity, low-pressure pump mounting cavity, and plunger pump mounting cavity within the housing, this invention further includes a vibration damping cavity. This cavity not only effectively houses the first and second clutches, which serve as the transmission connection, facilitating overall product assembly, but also allows for the installation of a pump body vibration damping assembly within the cavity. The pump body vibration damping assembly includes a vibration absorber connected to the outer wall of the transmission mechanism mounting cavity and located within the vibration damping cavity. Annular vibration absorbing elements, sleeved around the drive shaft and transmission shaft, are fixed outwards on both sides of the vibration absorber. When the first clutch engages, the annular vibration absorbing elements sleeved around the drive shaft retract onto the drive shaft; when the second clutch engages, the annular vibration absorbing elements sleeved around the transmission shaft retract onto the transmission shaft.

[0024] During operation, power is input from an external power source. The engagement or disengagement of the first and second clutches is effectively switched as needed, thereby effectively controlling the low-pressure pump unit or plunger pump unit to operate independently or simultaneously to meet low-pressure and high-pressure water demands. During operation, vibrations generated by the transmission mechanism are directly transmitted to the vibration absorber for reduction. When the low-pressure pump unit or plunger pump unit is operating, the corresponding annular vibration absorber retracts to its input end. This effectively reduces the vibration of the low-pressure pump unit or plunger pump unit during operation and prevents excessive transmission of vibrations generated by the transmission mechanism, low-pressure pump unit, or plunger pump unit to the stationary low-pressure pump unit or plunger pump unit due to the pump body vibration damping components. Furthermore, under the premise of a single power source, the low-pressure pump unit and plunger pump unit are effectively integrated into one unit, reducing space occupation and maintaining operational stability after integration.

[0025] 2) The vibration absorber of the present invention includes a vibration absorbing shell, and an annular vibration absorbing component includes an inner elastic steel plate and an outer elastic steel plate arranged at intervals. The inner and outer elastic steel plates are respectively arranged in an arc shape, and their bottom ends are respectively fixed to the bottom sides of the vibration absorbing shell. Corresponding damping materials are filled between the inner and outer elastic steel plates and inside the vibration absorbing shell. The upper parts of both ends of the vibration absorbing shell are respectively provided with driving members capable of tightening and driving the inner and outer elastic steel plates. Under the action of the damping materials, the vibration absorber and the annular vibration absorbing component are ensured to have sufficient vibration damping and absorption effects; while under the action of the inner and outer elastic steel plates, it is ensured that the annular vibration absorbing component can disengage from the input end of the low-pressure pump unit or the plunger pump unit when not driven, thus ensuring the practical effect of the present invention.

[0026] 3) The inner elastic steel plate of the present invention is composed of two parallel arc-shaped steel plates, each with a corresponding abutting roller mounted at intervals. The driving component includes a first electromagnet for tightening the outer elastic steel plate and a set of second electromagnets for tightening the two arc-shaped steel plates. When the first clutch is engaged, the outer elastic steel plate, sleeved around the drive shaft, is tightened to the periphery of the drive shaft under the attraction of the first electromagnet. The set of second electromagnets is alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, causing the abutting rollers on different arc-shaped steel plates to roll and abut against the drive shaft respectively. Similarly, when the second clutch is engaged, the outer elastic steel plate, sleeved around the transmission shaft, is tightened to the periphery of the transmission shaft under the attraction of the first electromagnet. The set of second electromagnets is alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, causing the abutting rollers on different arc-shaped steel plates to roll and abut against the transmission shaft respectively.

[0027] By using two parallel arc-shaped steel plates and a set of second electromagnets that drive the two arc-shaped steel plates to compress, the annular vibration absorber of the present invention can effectively compress to the input end of the low-pressure pump unit or the plunger pump unit, and can achieve alternating changes in the compression rolling contact position. This prevents the input end (i.e., drive shaft, transmission shaft) of the low-pressure pump unit or the plunger pump unit from forming the same contact position for a long time during operation, thus effectively preventing excessive mechanical damage to the drive shaft and the transmission shaft, and thus effectively ensuring that the pump body vibration damping component of the present invention can be used more rationally.

[0028] 4) The arc-shaped steel plate of the present invention has a housing for mounting the abutment roller fixed at a position corresponding to the abutment roller. The ends of the abutment rollers extend through to the outside of the housing, and the housing is provided with corresponding oil injection holes. Lubricating grease is injected into the housing through the oil injection holes to reduce the friction between the abutment roller and the input end of the low-pressure pump unit or plunger pump unit, thereby helping to reduce excessive mechanical damage to the drive shaft and transmission shaft, and further improving the practical effect of the present invention.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] refer to Figures 1-6 An integrated dual-mode water pump includes:

[0038] The housing 1 is provided with a transmission mechanism mounting cavity 101, a low-pressure pump mounting cavity 102 and a plunger pump mounting cavity 103.

[0039] The transmission mechanism 2 includes a gear transmission assembly 201 installed in the transmission mechanism mounting cavity 101, and the output end of the gear transmission assembly 201 is connected to an external power source.

[0040] The low-pressure pump unit 3 includes a pump wheel 301 rotatably mounted in the low-pressure pump mounting cavity 102 via a corresponding drive shaft 302. The drive shaft 302 is connected to the first power output shaft 202 of the gear transmission assembly 201 via a first clutch 4.

[0041] The plunger pump unit 5 includes a plunger pump cylinder 501 installed in the plunger pump mounting cavity 103, and the drive shaft 502 of the plunger pump cylinder 501 is connected to the second power output shaft 203 of the gear transmission assembly 201 via a second clutch 6.

[0042] The pump body vibration damping assembly 7 includes a vibration damping cavity 104 on the housing 1. The first clutch 4 and the second clutch 6 are respectively disposed in the vibration damping cavity 104. The pump body vibration damping assembly 7 includes a vibration absorber 701 connected to the outer wall of the transmission mechanism mounting cavity 101 and located in the vibration damping cavity 104. Annular vibration absorbing elements 702 are fixedly connected to both sides of the vibration absorber 701 and sleeved around the drive shaft 302 and the transmission shaft 502, respectively. When the first clutch 4 is engaged, the annular vibration absorbing elements 702 sleeved around the drive shaft 302 are tightened onto the drive shaft 302. When the second clutch 6 is engaged, the annular vibration absorbing elements 702 sleeved around the transmission shaft 502 are tightened onto the transmission shaft 502.

[0043] This invention, based on the transmission mechanism mounting cavity 101, low-pressure pump mounting cavity 102, and plunger pump mounting cavity 103 within the housing 1, further includes a vibration damping cavity 104. This cavity not only effectively houses the first clutch 4 and the second clutch 6, which serve as the transmission connection, facilitating overall product assembly, but also allows for the installation of the pump body vibration damping assembly 7 within the cavity. During operation, power is input from an external power source (drive motor), and the engagement or disengagement of the first clutch 4 and the second clutch 6 is effectively switched as needed. This effectively controls the low-pressure pump unit 3 or the plunger pump unit 5 to operate independently or simultaneously, meeting low-pressure and high-pressure water demand. During equipment operation, the vibration generated by the transmission mechanism 2 is directly transmitted to the vibration absorber 701 for reduction. When the low-pressure pump unit 3 or the plunger pump unit 5 is operating, the corresponding annular vibration absorber 702 is tightened to its input end. This effectively reduces the operating vibration of the low-pressure pump unit 3 or the plunger pump unit 5 during operation and prevents the vibration generated by the transmission mechanism 2, the low-pressure pump unit 3, or the plunger pump unit 5 from being excessively transmitted to the low-pressure pump unit 3 or the plunger pump unit 5 when it is not in operation due to the setting of the pump body vibration damping component 7. Thus, under the premise of driving by a single power source, the low-pressure pump unit 3 and the plunger pump unit 5 are effectively integrated into one unit, which effectively reduces space occupation and effectively maintains the operational stability of the low-pressure pump unit 3 and the plunger pump unit 5 after integration.

[0044] The vibration absorber 701 includes a vibration-absorbing shell, and the annular vibration-absorbing component 702 includes an inner elastic steel plate 7021 and an outer elastic steel plate 7022 arranged at intervals. The inner elastic steel plate 7021 and the outer elastic steel plate 7022 are respectively arranged in an arc shape, and their bottom ends are respectively fixed to the bottom sides of the vibration-absorbing shell. Corresponding damping materials 8 are filled between the inner elastic steel plate 7021 and the outer elastic steel plate 7022 and inside the vibration-absorbing shell. The upper parts of both ends of the vibration-absorbing shell are respectively provided with driving components 9 capable of tightening the inner elastic steel plate 7021 and the outer elastic steel plate 7022. In this embodiment, the damping material 8 is a polymer damping material or a sheet-like damping plate.

[0045] The vibration damping material 8 ensures that the vibration absorber 701 and the annular vibration absorber 702 have sufficient vibration damping and absorption effects; while the inner elastic steel plate 7021 and the outer elastic steel plate 7022 ensure that the annular vibration absorber 702 can disengage from the input end of the low-pressure pump unit 3 or the plunger pump unit 5 when not driven, thus ensuring the practical effect of the present invention.

[0046] The inner elastic steel plate 7021 is composed of two arc-shaped steel plates arranged side by side. Corresponding abutment rollers 10 are rotatably installed on the arc-shaped steel plates at intervals. The driving component 9 includes a first electromagnet 901 for tightening the outer elastic steel plate 7022 and a set of second electromagnets 902 for tightening the two arc-shaped steel plates respectively.

[0047] When the first clutch 4 is engaged, the outer elastic steel plate 7022, which is sleeved around the drive shaft 302, is tightened to the periphery of the drive shaft 302 under the attraction drive of the first electromagnet 901. A set of second electromagnets 902 are alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, so that the abutting rollers 10 on the different arc-shaped steel plates roll and abut against the drive shaft 302 respectively. When the second clutch 6 is engaged, the outer elastic steel plate 7022, which is sleeved around the transmission shaft 502, is tightened to the periphery of the transmission shaft 502 under the attraction drive of the first electromagnet 901. A set of second electromagnets 902 are alternately energized to alternately attract and drive the corresponding arc-shaped steel plates, so that the abutting rollers 10 on the different arc-shaped steel plates roll and abut against the transmission shaft 502 respectively.

[0048] By using two parallel arc-shaped steel plates and a set of second electromagnets 902 that drive the two arc-shaped steel plates to compress, the annular vibration absorber 702 of the present invention can effectively compress to the input end of the low-pressure pump unit 3 or the plunger pump unit 5, and can achieve alternating changes in the compression rolling contact position. This prevents the input end (i.e., drive shaft, transmission shaft) of the low-pressure pump unit 3 or the plunger pump unit 5 from rubbing against the annular vibration absorber 703 at the same contact position for a long time during operation, thereby effectively preventing excessive mechanical damage to the drive shaft 302 and the transmission shaft 502, and thus effectively ensuring that the pump body vibration damping component 7 of the present invention can be used more rationally.

[0049] The arc-shaped steel plate is fixed with a housing 11 for mounting the abutting roller 10 at a position corresponding to the abutting roller 10. The ends of the abutting roller 10 extend through to the outside of the housing 11. The housing 11 is provided with corresponding oil injection holes. Lubricating grease is injected into the housing 11 through the oil injection holes to reduce the friction between the abutting roller 10 and the input end of the low-pressure pump unit 3 or the plunger pump unit 5, thereby helping to reduce excessive mechanical damage to the drive shaft 302 and the transmission shaft 502, and thus further improving the practical effect of the present invention.

[0050] The output speed of the first power output shaft 202 is lower than the output speed of the second power output shaft 203.

[0051] The ports of the transmission mechanism mounting cavity 101, the low-pressure pump mounting cavity 102, the plunger pump mounting cavity 103, and the vibration damping cavity 104 are respectively fixedly installed with corresponding sealing end caps 12.

[0052] The low-pressure pump mounting cavity 102 is provided with a corresponding low-pressure water outlet 1021, and the sealing end cap 12 installed on the low-pressure pump mounting cavity 102 is provided with a corresponding low-pressure water inlet 13.

[0053] The sealing end cap 12 installed on the piston pump mounting cavity 103 is provided with a high-pressure water inlet 14 and a high-pressure water outlet 15.

[0054] Both the first clutch 4 and the second clutch 6 are wet multi-plate clutches.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
