Water pump with noise reduction effect

Abstract

The present invention discloses a water pump with noise reduction effect, which specifically relates to the technical field of water pumps. By arranging a protective shell, a sealing plate and a connecting bottom plate, since the noise reduction layer is a frosted noise reduction plate, and the interior of the noise reduction layer adopts a method of opening multi-angle slots, the noise generated when the driving motor is running will first propagate inside the noise reduction plate, and the sound will be transmitted to the multi-angle slots. At this time, the multi-angle slots will reflect the sound and increase the distance of the sound reflection by multi-angle reflection. When the sound is transmitted to the outside world, the intensity of the sound transmitted to the outside world will be greatly reduced due to the long transmission distance. At the same time, the driving motor is assisted in heat dissipation by the sliding sleeve and the sliding plate, thereby ensuring the noise reduction effect of the water pump while avoiding overheating and damage to the water pump, and further improving the service life and operation efficiency of the water pump while ensuring the health of personnel.

Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and more particularly to a water pump with noise reduction effect. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensoids, and liquid metals. It can also transport liquid and gas mixtures and liquids containing suspended solids.

[0003] Currently, most water pumps operate by rotating an impeller driven by a motor, which pumps and discharges liquid through the pump body. However, in actual use, because water pumps are often located close to a water source, the motor is easily exposed to high humidity, making it difficult to ensure safe operation. Furthermore, during operation, the rotation of the internal rotor can loosen the base screws. This, coupled with the electromagnetic torque of the motor, can cause abnormal vibrations in the motor. Over time, the bearings within the motor wear, and the rotor can become severely eccentric, causing friction between the stator and rotor. This results in intense vibrations and uneven collisions, generating a significant amount of noise. Currently, to ensure effective heat dissipation, buffering and shock-absorbing structures are often used to reduce the vibration amplitude of the motor. However, this still remains difficult to completely shield against the noise generated by the motor. Prolonged work in noisy environments can easily lead to symptoms such as tinnitus, which is detrimental to physical and mental health. Furthermore, prolonged motor vibration exacerbates rotor wear, significantly shortening the pump's service life and significantly reducing its operating efficiency. Summary of the Invention

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention provides a protective shell, a sealing plate and a connecting bottom plate. Since the noise reduction layer is a frosted noise reduction plate and the interior of the noise reduction layer is provided with multi-angle slots, the noise generated when the driving motor is running will first propagate inside the noise reduction plate. At this time, the sound will be transmitted to the multi-angle slots. At this time, the multi-angle slots will reflect the sound and increase the distance of sound reflection through multi-angle reflection. When the sound is transmitted to the outside world, the intensity of the sound transmitted to the outside world will be greatly reduced due to the long transmission distance. At the same time, the sliding sleeve and the sliding plate assist in heat dissipation of the driving motor, thereby ensuring the noise reduction effect of the water pump while avoiding overheating and damage to the water pump, thereby further improving the service life and operating efficiency of the water pump while protecting the health of personnel;

[0016] 2. The present invention provides a fan assembly, a protective shell, an external heat sink and a heat dissipation contact sheet. When the fan assembly is in operation, gas will enter the protective shell through the positioning sealing sheet and the air inlet hole, thereby accelerating the air flow rate inside the protective shell. At this time, the gas will carry part of the heat on the surface of the sleeve and the slide plate in the process of passing through the interior of the protective shell, and discharge the gas into the interior of the sealing box through the through hole. When the water pump is in use, the operation of the fan assembly can accelerate the heat dissipation inside the protective shell, thereby avoiding the heat dissipation effect of the drive motor being affected by the arrangement of the protective shell. Moreover, since the sleeve passes through the protective shell and is connected to the external heat sink, the heat dissipation contact sheet will transfer the heat to the outside through the slide plate and the sleeve after absorbing the heat, and cool it down through the external heat sink, thereby further ensuring the heat dissipation effect of the water pump when it is in operation, avoiding the drive motor being damaged due to the high temperature generated when the drive motor is in operation, and thus ensuring the service life of the water pump.

[0017] 3. The present invention provides a sealing box, an inclined plate and a positioning slot. When gas enters the sealing box through the through hole, the gas will squeeze the inclined plate. Since the inclined plate is inclined, the gas will squeeze the inclined plate to move, causing the inclined plate to push the extrusion rod downward and be discharged through the other side of the sealing box. Since the inclined plate pushes the extrusion rod and the positioning block to move downward, at this time, the positioning block will be clamped on the surface of the positioning bolt through the positioning slot, making it difficult for the positioning bolt to rotate due to the vibration generated by the drive motor or the water pump during operation, thereby reducing the problem of the positioning bolt being difficult to fix the water pump due to its own rotation, thereby reducing the noise caused by the loose installation connection part of the water pump.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-6As shown, the present invention provides a water pump with noise reduction effect, including a positioning base 1, the upper surface of the positioning base 1 is fixedly connected to two pin shafts 2, the positioning base 1 is hinged to the opposite surfaces of the two connecting base plates 3 through the two pin shafts 2, and the upper surfaces of the two connecting base plates 3 are fixedly connected to the lower surfaces of the two protective shells 4, a plurality of elastic components 6 are fixedly connected inside the protective shell 4, and an external heat sink 8 is connected to the outer surface of the protective shell 4. Due to the provision of the external heat sink 8, when the sliding sleeve 601 and the slide plate 602 absorb heat through the heat dissipation contact sheet 7, the heat is transferred to the external heat sink 8 provided outside the protective shell 4 for heat dissipation, thereby further ensuring the heat dissipation effect of the water pump during operation, avoiding damage to the drive motor 30 due to the high temperature generated when the drive motor 30 is running, and thus ensuring the service life of the water pump. The inner wall of the outer heat sink 8 is fixedly connected to one end of the elastic component 6, and sealing plates 10 are fixedly connected to both sides of the two protective shells 4. The opposing surfaces of the two sealing plates 10 located in the front and the opposing surfaces of the two sealing plates 10 located in the rear are interlocked, and the two sealing plates 10 located in the rear are attracted to each other via magnetic blocks. The protective shell 4 includes a noise reduction layer 401, which is a frosted noise reduction plate. The noise reduction layer 401 has a plurality of multi-angle slots 404 formed therein. The heat dissipation layer 402 is fixedly connected to the outside of the noise reduction layer 401. Due to the multi-angle slots 404, when sound is transmitted within the protective shell 4, the multi-angle slots 404 will reflect the sound, and the multi-angle reflection method increases the distance of the sound reflection. When the sound is transmitted to the outside world, the sound intensity transmitted to the outside world will be greatly reduced due to the long propagation distance, thereby improving the noise reduction effect of the water pump. The heat dissipation layer 402 is configured as a mesh-type heat sink, and a protective layer 403 is provided outside the heat dissipation layer 402. The protective layer 403 is configured as a metal protective plate. The noise reduction layer 401, the heat dissipation layer 402, and both sides of the protective layer 403 are fixedly connected to the opposing surfaces of the two sealing plates 10. The opposing surfaces of the two front sealing plates 10 are each provided with mounting slots 5. Due to the provision of the noise reduction layer 401, the sliding sleeve 601, and the sliding plate 602, when sound propagates within the protective housing 4, the noise reduction layer 401 can absorb and reflect sound over long distances. At the same time, the sliding sleeve 601 and the sliding plate 602 assist in dissipating heat from the drive motor 30. This ensures the water pump's noise reduction effect while preventing overheating and damage. This further improves the water pump's service life and operating efficiency while protecting personnel health.

[0027] like Figure 1 、 Figure 3 Figure 4 and Figure 5As shown, the other end of the elastic component 6 is fixedly connected to the heat dissipation contact sheet 7, and the elastic component 6 includes a sliding sleeve 601, which is fixedly connected to the noise reduction layer 401, the heat dissipation layer 402 and the protective layer 403. The sliding sleeve 601 passes through the noise reduction layer 401, the heat dissipation layer 402 and the protective layer 403 and is fixedly connected to the outer heat dissipation fin 8. A slide plate 602 is slidably connected to the sliding sleeve 601. Because a first spring 603 is provided, when the drive motor 30 is sealed for noise reduction through the two protective shells 4, the heat dissipation contact sheet 7 will contact the surface of the drive motor 30. At this time, the first spring 603 will squeeze the heat dissipation contact sheet 7 by squeezing the slide plate 602, thereby ensuring that the heat dissipation contact sheet 7 is always in contact with the surface of the drive motor 30. In a fitted state, and making the water pump suitable for different types of drive motors 30, two first springs 603 are arranged in the sleeve 601, and the two ends of the two first springs 603 located in the same sleeve 601 are respectively fixedly connected to one side of the inner wall of the sleeve 601 and one end corresponding to the slide 602, and the other end of the slide 602 is fixedly connected to one side of the heat dissipation contact sheet 7, the sleeve 601 and the slide 602 are respectively copper sleeves and copper slides. Since the sleeve 601 and the slide 602 are respectively copper sleeves and copper slides, the heat dissipation contact sheet 7 can be transferred to the external heat dissipation sheet 8 through the sleeve 601 and the slide 602 after absorbing the heat dissipated by the drive motor 30, further ensuring the heat dissipation effect of the water pump during operation.

[0028] The lower surfaces of the sealing plate 10 and the connecting bottom plate 3 are overlapped with the upper surface of the positioning base 1. The two sealing plates 10 located in the front are both provided with through holes 9, and the backs of the two sealing plates 10 located in the rear are both provided with limiting slides 11. The limiting slides 11 are set to be arc-shaped. Because the limiting slides 11 are arc-shaped, when the protective shell 4 and the sealing plate 10 are flipped along the pin shaft 2, the positioning sealing piece 14 will slide in the limiting slides 11, avoiding the positioning sealing piece 14 from hindering the flipping of the sealing plate 10 during the flipping process of the sealing plate 10, and at the same time ensuring the connection effect of the positioning sealing piece 14 and the sealing plate 10 after merging. A positioning groove 12 is provided in the limiting slide 11, and a positioning sealing piece 14 is clamped in the positioning groove 12.

[0029] like Figure 1 、 Figure 2 Figure 3 and Figure 6As shown, the shape of the positioning sealing piece 14 is adapted to the shape of the positioning groove 12, and an air inlet hole 13 is opened in the positioning groove 12. The positioning sealing piece 14 is connected to the sealing plate 10 through the air inlet hole 13. The other side of the positioning sealing piece 14 is fixedly connected to a transfer pipe 15, and the other end of the transfer pipe 15 is fixedly connected to a first conduit 16. Because a fan assembly 19 is provided, when the fan assembly 19 discharges the gas into the protective shell 4 through the first conduit 16, the second conduit 17 and the three-way connecting pipe 18, the gas will carry part of the heat on the surface of the sleeve 601 and the slide plate 602 in the process of passing through the interior of the protective shell 4, and discharge the gas into the interior of the sealing box 23 through the through hole 9, so that the water pump can accelerate the heat dissipation inside the protective shell 4 through the operation of the fan assembly 19 during use, thereby avoiding the heat dissipation effect of the drive motor 30 being affected by the setting of the protective shell 4.

[0030] The positioning sealing piece 14 is connected to the first conduit 16 through the adapter tube 15, and the other ends of the two first conduits 16 are respectively connected to the two second conduits 17, and the second conduits 17 are connected to the fan assembly 19 through the three-way connecting pipe 18. The lower surface of the fan assembly 19 is fixedly connected to the upper surface of the mounting plate 20, the lower surface of the mounting plate 20 is fixedly connected to the upper surface of the support frame 21, and the lower surface of the support frame 21 is fixedly connected to the upper surface of the positioning base 1. The through holes 9 opened on the front of the two sealing plates 10 in the front are each provided with a connecting pipe 22, which is located in the front. The two sealing plates 10 are connected to the back of the sealing box 23 through the through hole 9 and the connecting pipe 22. Because the inclined panel 25 is provided, the gas will contact the inclined panel 25 when entering the sealing box 23, and push the inclined panel 25 to move downward in the process of squeezing the inclined surface of the inclined panel 25, thereby ensuring that the gas can push the extrusion rod 271 to move downward through the inclined panel 25 when entering the sealing box 23, thereby ensuring the stability of the water pump during overall operation, and ventilation slots 24 are provided in both sealing boxes 23, and three inclined panels 25 are provided in the ventilation slots 24.

[0031] The shapes of the three inclined panels 25 are adapted to the shape of the inner wall of the ventilation groove 24. The lower surface of the inclined panel 25 is fixedly connected to the top of the elastic positioning device 27. The lower surface of the inner wall of the ventilation groove 24 is provided with three guide grooves 26. The elastic positioning device 27 is slidably connected in the guide groove 26. Because the positioning slots 274 and the positioning bolts 28 are provided, the water pump is not easily caused to rotate by the vibration generated by the driving motor 30 or the operation of the water pump during operation, thereby reducing the difficulty of the positioning bolts 28 in fixing the water pump due to rotation, thereby reducing the noise caused by loose installation and connection parts of the water pump. Six positioning bolts 28 are provided on the upper surface of the positioning base 1, and the six positioning bolts 28 are evenly installed on both sides of the upper surface of the positioning base 1. The position of the elastic positioning device 27 corresponds to the position of the positioning bolts 28.

[0032] like Figure 1 、 Figure 2 Figure 3 and Figure 4 As shown, the elastic positioning device 27 includes an extrusion rod 271, the top end of the extrusion rod 271 is fixedly connected to the lower surface of the inclined panel 25, the extrusion rod 271 is slidably connected in the guide slide groove 26, and a second spring 272 is fixedly connected to the outside of the extrusion rod 271. The two ends of the second spring 272 are respectively fixedly connected to the lower surface of the sealing box 23 and the outside of the extrusion rod 271. Due to the provision of the second spring 272, when the fan assembly 19 is closed, the second spring 272 will drive the extrusion rod 271 and the positioning block 273 to reset. At this time, the positioning bolt 28 can be removed, thereby improving the flexibility of the water pump when in use and avoiding affecting the installation and disassembly of the water pump.

[0033] The bottom end of the extrusion rod 271 is fixedly connected to a positioning block 273, and a positioning slot 274 is provided on the lower surface of the positioning block 273. The shape of the positioning slot 274 is adapted to the shape of the top of the positioning bolt 28. The top of the positioning bolt 28 is set as an inclined surface. The upper surface of the positioning base 1 is fixedly connected to the driving motor 30, and the other side of the heat dissipation contact plate 7 is attached to the outside of the driving motor 30. Because the top of the positioning bolt 28 is an inclined surface, when the positioning block 273 moves downward and contacts the positioning bolt 28 through the positioning slot 274, the positioning slot 274 can be attached to the positioning bolt 28 through the inclined surface, ensuring the fixing effect of the positioning bolt 28 and preventing the positioning bolt 28 from rotating due to vibration.

[0034] The output shaft of the drive motor 30 passes through the pump coupling protective shell 31 and is transmission-connected to the pump coupling 32. The lower surface of the pump coupling 32 shell is fixedly connected to the upper surface of the positioning base 1. The other end of the pump coupling 32 is transmission-connected to the output end of the water pump assembly 34 through the bracket 33. The lower surface of the bracket 33 is fixedly connected to the upper surface of the positioning base 1. The back of the positioning base 1 is fixedly connected with a filling sealing block 29, and the opposite surfaces of the two sealing plates 10 located at the rear are respectively clamped on both sides of the filling sealing block 29.

[0035] Working principle of the present invention: When using the water pump, the water pump needs to be fitted to the designated position through the positioning base 1 to ensure that the installation part is clean and tidy to avoid the presence of impurities causing a gap between the positioning base 1 and the installation part. Then, the positioning base 1 is fixed by the positioning bolt 28, and the positioning base 1 and the installation part are tightened by the thread on the surface of the positioning bolt 28. After tightening, it is necessary to flip the protective shells 4 on both sides along the pin shaft 2 so that the protective shells 4 on both sides are in contact with each other. At this time, the two sealing plates 10 at the rear will be attracted to each other through the magnetic block, thereby achieving a fixing effect, and the heat dissipation contact plate 7 will also be in contact with the surface of the drive motor 30, and will be fitted with the surface of the drive motor 30 under the action of the elastic force of the first spring 603, and the positioning sealing plate 14 will be connected to the air inlet 13, and the fan assembly 19 will be started subsequently.

[0036] When the fan assembly 19 is running, it will inject gas into the three-way connecting pipe 18, the second conduit 17 and the first conduit 16 by extracting external air. Then the gas will enter the protective shell 4 through the positioning sealing piece 14 and the air inlet 13, so that the air flow rate inside the protective shell 4 will be accelerated. At this time, the gas will carry part of the heat on the surface of the sliding sleeve 601 and the slide plate 602 in the process of passing through the interior of the protective shell 4, and discharge the gas to the inside of the sealing box 23 through the through hole 9.

[0037] And because the sleeve 601 passes through the protective shell 4 and is connected to the external heat sink 8, the heat dissipation contact plate 7 will transfer the heat to the outside through the slide plate 602 and the sleeve 601 after absorbing heat and cool it through the external heat sink 8. When the gas enters the sealing box 23 through the through hole 9, the gas will squeeze the inclined plate 25. Since the inclined plate 25 is inclined, the gas will squeeze the inclined plate 25 to move, so that the inclined plate 25 pushes the extrusion rod 271 to move downward. At this time, the gas entering the sealing box 23 will continue to squeeze the rear inclined plate 25 under the action of pressure and be discharged through the other side of the sealing box 23. Since the inclined plate 25 pushes the extrusion rod 271 and the positioning block 273 to move downward, at this time, the positioning block 273 will be clamped on the surface of the positioning bolt 28 through the positioning slot 274. When the fan assembly 19 is shut down, the second spring 272 will drive the extrusion rod 271 and the positioning block 273 to reset, so as to avoid affecting the disassembly of the water pump. When the driving motor 30 is running, the driving motor 30 drives the rotating shaft inside the bracket 33 to rotate through the pump coupling 32, and drives the water pump assembly 34 to operate through the rotating shaft.
