Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a detachable noise-reducing water pump. Background Art

[0002] Energy-saving water pumps are highly efficient energy-saving devices that can significantly reduce energy consumption, in response to the country's call for energy conservation and emission reduction. They are circulating centrifugal pump products with optimized designs, featuring constant flow and pressure, wear resistance and corrosion resistance, high self-priming height and efficiency. In the next few years, China will vigorously promote the application of high-efficiency energy-saving water pumps, bringing great development opportunities to the energy-saving water pump industry. Energy-saving water pumps are circulating centrifugal pump products with optimized designs and higher energy utilization efficiency. Compared with ordinary water pumps, energy-saving water pumps can reduce the actual power consumption of the driving device during actual use, thereby reducing energy consumption.

[0003] Vane pumps generally include vanes and impellers, and are divided into centrifugal pumps and axial flow pumps according to different working principles. The working principle of a centrifugal pump is to use the rotation of the impeller to generate centrifugal force, accelerating the fluid and making it flow along the flow path inside the pump casing. Vane pumps have the characteristics of compact structure, small size but large displacement, uniform flow rate, and stable operation. They are widely used not only in industrial and agricultural fields such as petroleum, chemical industry, water conservancy, and irrigation, but also as key equipment in high-tech fields such as nuclear power, aerospace, ships, and submarines. In a typical vane pump, the vanes are directly fixed to the hub. When a certain group of vanes is damaged, the entire hub part needs to be removed for replacement, which is not convenient for disassembly, and the protection of the water pump is poor, resulting in relatively high noise, which has an adverse impact on people's work and life. Summary of the Utility Model

[0004] One of the purposes of the present utility model is to provide a detachable noise-reducing water pump to solve the problems of inconvenient disassembly of the water pump vanes and relatively high noise generated by the water pump in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A detachable noise-reducing water pump includes a pump body housing provided with an inlet pipe and an outlet pipe, a rotating device located inside the pump body housing, a fixing device, and a driving device for driving the rotating device to rotate and installed on the fixing device. It is characterized in that it further includes a sound insulation device, the sound insulation device is provided with through holes for the inlet pipe and the outlet pipe to extend out respectively, the pump body housing is located inside the sound insulation device, the rotating device includes an impeller and vanes, the impeller is connected to the driving device, and the vanes are detachably connected to the impeller.

[0007] In the above technical solution, the fixing device is installed on an external fixture, the driving device is relatively fixed to the fixing device, the water inlet pipe is connected to the water tank. Before starting the driving device, it is necessary to fill the pump housing and the water inlet pipe with water, and then start the driving device. The driving device drives the impeller and water to rotate at a high speed. The blades connected to the impeller also rotate at a high speed. Under the action of centrifugal force, the water will be thrown towards the outer edge of the blade. When the high-speed rotating water passes through the water outlet, it will gush out from the water outlet pipe under the action of inertia. The water in the pump housing decreases, so a vacuum will be formed at the center of the water pump impeller. The water in the water tank will be pressed into the pump housing under the action of atmospheric pressure. The impeller keeps rotating, making the water continuously flow in and out under the action of the impeller, achieving the purpose of water transportation. The pump housing is located inside the sound insulation device. The sound insulation device reduces the noise during the propagation of the noise, blocks part of the noise generated during the operation of the water pump, reduces the impact of the noise on people. At the same time, the setting of the sound insulation device can also protect the pump housing from external damage. The blades and the impeller are designed to be detachably connected. Usually, the blades and the impeller are relatively fixed. When the blades need to be replaced or repaired, they can be disassembled, which is convenient for disassembly and assembly and has better convenience.

[0008] Preferably, the sound insulation device includes a protective cover and a cover plate for covering the protective cover. Both the protective cover and the cover plate are made of sound insulation materials. The design of the cover plate makes a sealed cavity formed between the entire sound insulation device and the pump housing, with better sealing performance and better sound insulation ability. Compared with ordinary materials, sound insulation materials have stronger sound insulation ability, reduce noise, and better reduce the impact of noise on people.

[0009] Preferably, the protective cover is provided with insertion holes, and the cover plate is provided with insertion posts, and the insertion posts are installed in the insertion holes. The cooperation of the insertion posts and insertion holes makes the disassembly and installation of the cover plate and the protective cover simpler. Usually, the cover plate and the protective cover are closed to form a sealed cavity with the pump housing. When the water pump needs to be inspected and repaired, the cover plate can be quickly removed, which is convenient for inspecting and repairing the water pump and has better convenience.

[0010] Preferably, the sound insulation device further includes a sound absorption layer, and the sound absorption layer is located between the cavity formed by the protective cover and the cover plate and the pump housing. The setting of the sound absorption layer further reduces the noise during the propagation of the noise. Compared with the cavity, the sound absorption layer has stronger noise reduction ability, reduces noise, and better reduces the impact of noise on people.

[0011] Preferably, the sound absorption layer is sound absorption cotton. Cotton has a multi-fiber structure. When sound waves pass through cotton, they are reflected, superposed, and collided by countless fibers, reducing noise and better reducing the impact of noise on people.

[0012] Preferably, a first sliding groove is provided on the fixing device. The first sliding groove is a T-shaped groove, and the sound insulation device is slidably connected to the first sliding groove. The provision of the first sliding groove facilitates the disassembly and installation of the sound insulation device and the fixing device. The T-shaped groove restricts the movement of the sound insulation device and the fixing device in other directions except for relative sliding, providing better stability. At the same time, this relatively tight fit reduces the vibration and collision between the two devices during the operation of the water pump, reduces noise, and better reduces the impact of noise on people.

[0013] Preferably, a number of second sliding grooves are provided on the outer peripheral surface of the impeller. The blades are installed in the second sliding grooves and are slidably connected to the second sliding grooves. A locking member is provided on the second sliding groove, and the blade is fixed to the second sliding groove through the locking member. The provision of the second sliding groove facilitates the disassembly and installation between the blade and the impeller, providing better convenience. The provision of the locking member can fix the blade and fix the blade on the impeller to prevent relative sliding between the impeller and the blade when the impeller rotates.

[0014] Preferably, the locking member is a bolt, the second sliding groove is a T-shaped groove, the bolt is threadedly connected to the second sliding groove. One end of the second sliding groove is open and extends to the plane of the impeller, and the other end is a closed end. One end of the blade abuts against the bolt, and the other end abuts against the inner wall of the closed end of the second sliding groove. The T-shaped groove realizes the fixation between the blade and the impeller in the radial direction. Compared with directly connecting the blade and the impeller using screws, the contact area between the T-shaped groove and the blade is larger, providing better stability. The second sliding groove is provided in a form with one end open and the other end closed. Therefore, only one bolt needs to be provided at the open end of the second sliding groove to realize the axial fixation of the blade, making the disassembly and assembly faster and providing better convenience.

[0015] Preferably, the driving device is a motor, which can convert electrical energy into mechanical energy. The output shaft of the motor is fixedly connected to the impeller. When the motor is turned on, it can drive the output shaft to rotate at a high speed, thereby driving the impeller disk fixedly connected thereto to rotate at a high speed. It has a smaller volume and higher efficiency.

[0016] Preferably, a filter screen is covered on the water inlet of the water inlet pipe. The filter screen can filter the water entering the water pump from the water inlet pool, prevent hard solids from entering the pump body housing and colliding with the high-speed rotating blades, causing damage to the blades, and improving the service life of the device.

[0017] Advantages of the present utility model: The pump body housing is located inside the sound insulation device, which reduces noise during the propagation of noise, blocks part of the noise generated during the operation of the water pump, reduces the impact of noise on people. At the same time, the setting of the sound insulation device can also protect the pump body housing and prevent it from being damaged by the outside. The blades and the impeller are designed to be detachably connected, which is convenient for disassembly and assembly and has better convenience. Brief Description of the Drawings

[0023] Such as Figures 1-3Shown is Embodiment 1 of a detachable noise-reducing water pump, including a pump body housing 1 provided with a water inlet pipe 101 and a water outlet pipe 102, a rotating device 2 located inside the pump body housing 1, a fixing device 3, a sound insulation device 5 wrapping the pump body housing 1, and a driving device 4 for driving the rotation of the rotating device 2 and mounted on the fixing device 3. The sound insulation device 5 includes a protective cover 501, a cover plate 502 for covering the protective cover 501, and a sound absorption layer 503. In this embodiment, the sound absorption layer 503 is two pieces of sound absorption cotton. In addition, it can also be a sound insulation board, a sound absorption foam, a composite layer composed of various sound absorption materials, etc. Both the protective cover 501 and the cover plate 502 are sound insulation materials. The cover plate 502 is located at one end of the protective cover 501. The protective cover 501 is provided with a jack 504; the cover plate 502 is provided with a plug post 505, and the plug post 505 is installed in the jack 504. When the cover plate 502 and the protective cover 501 are closed, their outer surfaces enclose a cube. The pump body housing 1 is located inside the sound insulation device 5. Two symmetrically installed pieces of sound absorption cotton are filled between the cavity formed by the protective cover 501 and the cover plate 502 and the pump body housing 1. Among them, a through hole is opened on the sound absorption cotton near the water outlet. Through holes are also provided on the cover plate 502 and the protective cover 501. The water inlet pipe passes through the through hole on the protective cover 501, and the water outlet pipe 102 passes through the through hole of the sound absorption cotton and the through hole on the cover plate 502. The rotating device 2 includes an impeller 201 and a number of blades 202. The impeller 201 is connected to the driving device 4, and the blades 202 are detachably connected to the impeller 201. In this embodiment, the fixing device 3 is two parallel bases. The bases support the ground, and the two bases are fixedly connected to the driving device 4 by bolts. In addition, it can also be rivet connection, welding, etc. A first sliding groove 301 is provided on both bases. In this embodiment, the first sliding groove 301 is a T-shaped groove. In addition, it can also be a V-shaped groove, a dovetail groove, etc. A slider matching with the T-shaped groove is provided at the bottom of the sound insulation device 5, and the slider is slidably connected in the T-shaped groove.

[0024] Specifically, when using this water pump, the fixing device 3 is installed on an external fixture, the driving device 4 is fixedly connected to the fixing device 3, the water inlet pipe 101 is connected to a water pool. Before starting the driving device 4, the pump body housing 1 and the water inlet pipe 101 must be filled with water. Then, start the driving device 4. The driving device 4 drives the impeller 201 and water to rotate at a high speed. The blades 202 connected to the impeller 201 also rotate at a high speed. Under the action of centrifugal force, the water is thrown towards the outer edge of the blades 202. When the high-speed rotating water passes through the water outlet, it will gush out from the water outlet pipe 102 under the action of inertia. The water in the pump body housing 1 decreases, so a vacuum will be formed at the center of the water pump impeller 201. The water in the water pool will be pressed into the pump body housing 1 under the action of atmospheric pressure. The impeller 201 keeps rotating, making the water continuously flow in and out under the action of the impeller 201, achieving the purpose of transporting water. When the water pump is working, it will continuously generate noise and spread in all directions. On the noise propagation path, the sound-absorbing cotton, the protective cover 501 and the cover plate 502 can reflect, superpose and collide with the noise, so as to reduce the noise and the impact of the noise on people. At the same time, the cover plate 502 and the protective cover 501 are connected by inserting the post 505 into the hole 504, and the cover plate 502 and the protective cover 501 are slidably connected by inserting the post 505 into the hole 504. The blades 202 and the impeller 201 are detachably connected. When working, the components can be quickly installed. When some components need to be repaired or replaced, the target components can be quickly disassembled, which is more convenient.

[0025] Advantages of this embodiment: The pump body housing 1 is located inside the sound insulation device 5. The setting of the sound absorption layer 503 reduces the noise during the propagation process of the noise, blocks part of the noise generated when the water pump is working, and reduces the impact of the noise on people. At the same time, the setting of the sound insulation device 5 can also protect the pump body housing 1 from being damaged by the outside. The cover plate 502 and the protective cover 501 are movably connected by inserting the post 505 into the hole 504, the sound insulation device 5 is slidably connected to the fixing device 3, and the blades 202 and the impeller 201 are designed to be detachably connected, making it convenient to disassemble and assemble the components of this device, and the convenience is better.

[0026] Embodiment 2

[0027] Such as Figure 3 And Figure 4Shown is Embodiment 2 of a detachable noise reduction water pump. The difference from Embodiment 1 is that a number of second sliding grooves 203 are provided on the outer peripheral surface of the impeller 201. In this embodiment, the second sliding grooves 203 are T-shaped grooves. In addition, they can also be V-shaped grooves, dovetail grooves or other grooves that limit the radial movement of the blades 202. One end of the second sliding groove 203 is an open end and extends to the plane of the impeller 201, and the other end is a closed end located inside the impeller 201. The blade 202 is installed in the second sliding groove 203 and is slidably connected to the second sliding groove 203, thereby realizing the radial fixation between the blade 202 and the impeller 201. A locking member 204 is provided on the second sliding groove 203. In this embodiment, the locking member 204 is a bolt. One end of the blade 202 abuts against the bolt, and the other end abuts against the inner wall of the closed end of the second sliding groove 203, thereby realizing the axial fixation of the blade 202.

[0028] Another implementation manner of the locking member 204 is provided here. The difference from the above implementation manner is that a groove is provided on the second sliding groove 203. The locking member 204 is a limiting block fixedly connected to a spring at one end. The locking member 204 is installed in the groove and the spring is fixedly connected to the inner wall of the groove. In the static state, the limiting block extends out of the second sliding groove 203. When installing the blade 202, only need to press down the limiting block and slide the blade 202 into the second sliding groove 203. When one end of the blade 202 abuts against the inner wall of the second sliding groove 203, release the limiting block, and the limiting block will rebound under the action of the spring and abut against the other end of the blade 202, thereby realizing the fixation between the blade 202 and the impeller 201. Similarly, when disassembling the blade 202, only need to press the limiting block and slide the blade 202 to take out the blade 202 from the second sliding groove 203. Compared with the above implementation manner, the advantage of this implementation manner is that it is more convenient and efficient to disassemble and assemble the blade 202.

[0029] Another implementation manner of the second sliding groove 203 is provided here. The difference from the above implementation manner is that both ends of the second sliding groove 203 extend to the plane of the impeller 201, and the locking members 204 are respectively installed at both ends of the sliding groove to abut against both ends of the blade 202, thereby realizing the fixation of the blade 202. The advantage of this implementation manner is that the blade 202 can be disassembled in two directions. The limitation is that it consumes more materials and the fixing effect is not as good as the original implementation manner.

[0030] The remaining features and technical effects of the above implementation manners are the same as those of Embodiment 1.

[0031] Embodiment 3

[0032] As Figures 1-4Embodiment 3 of a detachable noise-reducing water pump shown, the difference from Embodiment 1 and Embodiment 2 is that the driving device 4 is a motor, the output shaft of the motor is fixedly connected to the impeller 201, the water inlet of the water inlet pipe 101 is covered with a filter screen, the motor can convert electrical energy into mechanical energy, and the output shaft of the motor is fixedly connected to the impeller 201. When the motor is turned on, it can drive the output shaft to rotate at a high speed, thereby driving the impeller disk fixedly connected thereto to rotate at a high speed. It has a smaller volume and higher efficiency. The filter screen can filter the water entering the water pump from the water inlet pool, prevent hard solids from entering the pump body housing 1 and colliding with the high-speed rotating blades 202, causing damage to the blades 202, improving the service life. At the same time, it prevents hard solids from being ejected and causing damage to the device or people, with better safety.

[0033] The remaining features and technical effects of this embodiment are the same as those of Embodiment 1 and Embodiment 2.

[0034] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are within the protection scope of the present invention.
