Description

Technical Field

[0001] The present application relates to the field of water pump noise reduction, and in particular to a water pump with a sound reduction and noise elimination structure. Background Art

[0002] Water pump noise is the irregular, intermittent, continuous or random noise generated by the water pump when it is running. It is low-frequency noise (sound with a frequency below 500 Hz). It is characterized by strong penetration, slow attenuation, long sound waves, and its diffraction waves can easily bypass obstacles. Therefore, low-frequency noise is not easy to deal with. The water pump noise comes from the noise of its own operation, the pipeline resonance noise caused by the water pump operation, and the water flow movement and impact noise caused by the water pump operation.

[0003] Since the noise of the water pump comes from many aspects, the best way to deal with it is to install a noise-isolating silencer outside the water pump. Most of the existing silencers need to be customized according to the working environment of the water pump and then transported and installed. However, this is not practical in some water rooms with small spaces. It is difficult to assemble and install, and it is very easy to cause component damage during transportation, affecting the final silencing effect.

[0004] In the construction industry, there is a relatively mature prefabricated technology, which is a technology that designs the target object into multiple modules, produces them separately, and finally assembles them on the site of use. On the one hand, transporting each component separately can greatly increase the safety of transportation and is not easy to cause damage to the components. On the other hand, each component is interchangeable with each other. Even if it is damaged during transportation, it can be replaced with a new component to reduce costs. At the same time, on-site assembly can also adapt to water rooms with relatively small spaces. Summary of the invention

[0005] The purpose of the present application is to solve the problem in the prior art that the formed small speaker is difficult to transport and install due to its large volume. Compared with the prior art, a water pump with a sound reduction and noise reduction structure is provided. The prefabricated base includes a base body, a plurality of sliding grooves are excavated on the base body, and guide grooves are respectively excavated on the side walls of the plurality of sliding grooves close to the water pump body. The plurality of sliding grooves are slidably connected with a sound-absorbing side wall. The sound-absorbing side wall includes a wall body, and the ends of the plurality of wall bodies close to each other are wedge-shaped ends that match each other. The ends of the plurality of wall bodies close to the water pump body are fixedly connected with guide blocks that match the guide grooves. Fixed plugs are embedded between the ends of the plurality of wall bodies away from the water pump body and the side walls of the sliding grooves. The ends of the plurality of wall bodies away from the sliding grooves are excavated with placement grooves. The upper ends of the plurality of sound-absorbing side walls are placed with sound-absorbing top plates. A buffer pad is connected between the sound-absorbing side wall and the sound-absorbing top plate. The buffer pad is fixedly connected to the sound-absorbing top plate, and the end of the buffer pad close to the sound-absorbing side wall is embedded in the placement groove. The sound-absorbing side wall and the sound-absorbing top plate are made of hollow glass.

[0006] The noise reduction and silencing structure can be divided into multiple modules, which are transported separately to the water room for unified installation, greatly reducing the difficulty of transportation and installation.

[0007] Furthermore, the prefabricated base is made of a porous multi-molecular material, and the surface of the prefabricated base is sprayed with paint to form a smooth surface, thereby improving the sound-absorbing effect of the prefabricated base, while not easily affecting the sealing effect between the prefabricated base and the sound-absorbing side wall.

[0008] Furthermore, the buffer pad includes an elastic pad, a buffer cavity is bored in the elastic pad, and the buffer cavity is filled with a buffer solution, so as to reduce the influence of the vibration generated by the silencer side wall during the silencer process on the silencer top plate and increase the overall stability of the sound reduction and noise reduction structure.

[0009] Furthermore, the buffer cavity is filled with a plurality of buffer balls, which are all suspended in the buffer solution, and the plurality of buffer balls are all hollow structures, and the buffer effect is increased by utilizing the collision between the plurality of buffer balls.

[0010] Furthermore, the outer walls of the multiple buffer balls are coated with a magnetic coating, and the magnetic coatings on the multiple buffer balls are like magnetic poles. After the buffer balls collide, they can be quickly separated and maintain a relatively stable distance between each other to increase the buffering effect.

[0011] Furthermore, the total volume of the plurality of buffer balls accounts for one quarter of the volume of the buffer cavity, which reserves sufficient movement space for the buffer balls and increases the overall shock-absorbing effect of the buffer pad.

[0012] Optionally, a magnetic strip is embedded in the inner wall of the guide groove, and the guide block is made of magnetic material. The magnetic strip is adsorbed to the guide block, so that the sound-absorbing side wall can generate suction with the prefabricated base during installation, maintain relative stability, and reduce the difficulty of installation.

[0013] Furthermore, the fixing plug includes a plug body, a serrated groove is bored in the plug body, and the serrated groove is filled with an air-hardening gel material. During the noise reduction process of the sound-absorbing side wall, vibration is generated, which impacts the fixing plug, causing the fixing plug to rupture, and the air-hardening gel material flows out and solidifies, fixing the prefabricated base and the fixing plug to be fixedly connected, thereby increasing the fastening effect of the fixing plug.

[0014] Furthermore, a plurality of sawtooth grooves are cut at one end of the plug body away from the muffler side wall, providing space for the air-hardening gel material to flow out, thereby increasing the fixing effect of the muffler side wall and the fixing plug.

[0015] Furthermore, a prefabricated groove is bored on the inner wall of the filling cavity, and the depth of the prefabricated groove is half of the thickness at the current position, so that the plug body can be easily torn at the position where the prefabricated groove is bored under the action of external force, thereby facilitating the air-hardening gel material to flow into the serrated groove.

[0016] Compared with the prior art, the advantages of this application are:

[0017] In this solution, the prefabricated base, sound-absorbing side walls, sound-absorbing top plate, buffer pads and fixing plugs are produced in a modular manner and transported separately to the installation location in the water room. The installation between the prefabricated base and the sound-absorbing side walls is achieved through a special structure to achieve mutual clamping, which reduces the difficulty of transportation and installation and reduces the possibility of damage during the overall transportation. The buffer pads are then used to separate the sound-absorbing side walls and the sound-absorbing top plate to reduce the wear of the sound-absorbing side walls and the sound-absorbing top plate caused by vibration. In the buffer pads, the collision of multiple buffer balls is used to increase the buffering effect. Through the reasonable design of the buffer balls, the buffer balls have the ability to maintain a relative distance and sufficient spacing without being subject to external forces, and a sufficient number of movement spaces are reserved for the buffer balls to increase the overall shock absorption effect of the buffer pads.

[0018] In addition, a specific structure of a fixing plug is designed for the prefabricated base and the silencer side wall. The vibration of the silencer side wall during operation is used to release the air-hardening gel material stored in the fixing plug, and the fixing plug is fixed to the prefabricated base to increase the fixing effect of the silencer side wall. This makes the assembly structure of the silencer side wall and the silencer top plate less likely to collapse, thereby increasing the overall stability of the noise reduction and silencer structure of the water pump body.

DETAILED DESCRIPTION

[0031] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0032] Embodiment 1:

[0033] The present invention provides a water pump with a noise reduction and noise elimination structure, please refer to Figure 1-4 , including a water pump body 1 fixedly connected to a prefabricated base 2, the prefabricated base 2 including a base body 201, a plurality of sliding grooves 202 are cut on the base body 201, a plurality of sliding grooves 202 are respectively cut on the side walls close to the water pump body 1 with guide grooves 203, a plurality of sliding grooves 202 are slidably connected with a muffler side wall 3, the muffler side wall 3 includes a wall body 301, a plurality of wall bodies 301 are close to each other at one end are mutually matched wedge ends, a plurality of wall bodies 301 are close to the water pump body 1 at one end are fixedly connected with the guide groove 20 3, a guide block 302 matching with the water pump body 1 is provided, a fixing plug 6 is embedded between one end of the multiple wall bodies 301 away from the water pump body 1 and the side wall of the sliding groove 202, a placement groove 303 is chiseled at one end of the multiple wall bodies 301 away from the sliding groove 202, a silencer top plate 4 is placed on the upper end of the multiple silencer side walls 3, a buffer pad 5 is connected between the silencer side wall 3 and the silencer top plate 4, the buffer pad 5 is fixedly connected to the silencer top plate 4, and one end of the buffer pad 5 close to the silencer side wall 3 is embedded in the placement groove 303, and the silencer side wall 3 and the silencer top plate 4 are made of hollow glass.

[0034] In this solution, the prefabricated base 2, each sound-absorbing side wall 3 and the sound-absorbing top plate 4 and the buffer pad 5 can be produced separately according to actual needs, and the inlet and outlet of the water delivery pipe of the water pump body 1 can be reserved on the prefabricated base 2, the sound-absorbing side wall 3 and the buffer pad 5 to facilitate subsequent installation. As for the specific installation position, it can be determined by technical personnel in this field after field investigation and design. This is a well-known technology of technical personnel in this field and is therefore not disclosed in detail in this application. Technical personnel in this field can make a reasonable design based on the existing technology.

[0035] After the various components of the present application are transported separately to the water room where they need to be installed, the water pump body 1 is fixedly connected to the prefabricated base 2, and then the four silencer side walls 3 are respectively inserted into the four sliding grooves 202, wherein the cooperation between the guide block 302 and the guide groove 203 can limit the movement of the silencer side wall 3. At this time, please refer to Fig.10 , multiple silencer side walls 3 are pushed in the direction shown in the figure at the same time, and when they move to the extreme position, they are stuck to each other. Since the thickness of the silencer side wall 3 is smaller than the width of the sliding groove 202, during the pushing process, multiple silencer side walls 3 can be slightly tilted outward to complete the displacement. After the silencer side walls 3 are assembled in place, the gaps between the silencer side walls 3 and the sliding grooves 202 are filled with fixing plugs 6 to complete the fixation of the silencer side walls 3. Then, the silencer top plate 4 and the buffer pad 5 are covered on the silencer side walls 3, and the installation is completed by using the weight of the silencer top plate 4 itself.

[0036] During the installation process of the entire sound reduction and noise reduction structure of the water pump body 1, it is divided into modules consisting of a prefabricated base 2, a sound-absorbing side wall 3, a sound-absorbing top plate 4, a buffer pad 5 and a fixing plug 6, which are transported separately and finally assembled in the water room. The installation between the prefabricated base 2 and the sound-absorbing side wall 3 is achieved by mutual clamping through a special structure, which reduces the difficulty of transportation and installation. The sound reduction and noise reduction structure mainly eliminates external noise through the structure of the sound-absorbing side wall 3 and the sound-absorbing top plate 4 itself.

[0037] See also Figure 4-7 The prefabricated base 2 is made of a porous multi-molecular material, and the surface of the prefabricated base 2 is sprayed with paint to form a smooth surface, which improves the sound-absorbing effect of the prefabricated base 2 and is not easy to affect the sealing effect between the prefabricated base 2 and the sound-absorbing side wall 3. The buffer pad 5 includes an elastic pad 501, and a buffer cavity 502 is excavated in the elastic pad 501. The buffer cavity 502 is filled with a buffer to reduce the impact of the vibration generated by the sound-absorbing side wall 3 during the sound-absorbing process on the sound-absorbing top plate 4, thereby increasing the overall stability of the sound-absorbing and noise-absorbing structure. The buffer cavity 502 is filled with a plurality of buffer balls 503, and the plurality of buffer balls 503 are filled with buffer balls 503. 03 are all suspended in the buffer, and the multiple buffer balls 503 are all hollow structures. The collision between the multiple buffer balls 503 is used to increase the buffering effect. The outer walls of the multiple buffer balls 503 are coated with a magnetic coating, and the magnetic coating on the multiple buffer balls 503 are like-sex magnetic poles. After the buffer balls 503 collide, they can be quickly separated and can maintain a relatively stable distance from each other to increase the buffering effect. The total volume of the multiple buffer balls 503 accounts for one-fourth of the volume of the buffer cavity 502, reserving enough movement space for the buffer balls 503, thereby increasing the overall shock-absorbing effect of the buffer pad 5.

[0038] Embodiment 2:

[0039] The present invention provides a water pump with a noise reduction and noise elimination structure, please refer to Figure 3-5 and Figure 8-9 , a magnetic strip is embedded in the inner wall of the guide groove 203, and the guide block 302 is made of magnetic material. The magnetic strip and the guide block 302 are adsorbed, so that the muffler side wall 3 can generate suction with the prefabricated base 2 during installation, maintain relative stability, and reduce the difficulty of installation. The fixed plug 6 includes a plug body 601, and a serrated groove 602 is cut in the plug body 601. The serrated groove 602 is filled with an air-hardening gel material. The muffler side wall 3 will vibrate during the noise reduction process, which will impact the fixed plug 6, causing the fixed plug 6 to rupture, and the air-hardening gel material will flow out and solidify, fixedly connecting the prefabricated base 2 and the fixed plug 6, thereby increasing the fastening effect of the fixed plug 6. In particular, during the installation process, in order to ensure that the fixing plug 6 is not broken, the staff can also scratch the fixing plug 6 by themselves. A plurality of serrated grooves 602 are chiseled at one end of the plug body 601 away from the silencer side wall 3 to provide space for the air-hardening gel material to flow out, thereby increasing the fixing effect of the silencer side wall 3 and the fixing plug 6. A prefabricated groove 604 is chiseled on the inner wall of the filling cavity 603, and the position of the prefabricated groove 604 matches the serrated groove 602. The depth of the prefabricated groove 604 is half of the thickness at the current position, so that the plug body 601 can be easily torn at the position where the prefabricated groove 604 is chiseled under the action of external force, thereby facilitating the air-hardening gel material to flow into the serrated groove 602.

[0040] Compared with Example 1, this embodiment further designs a specific structure of a fixing plug 6 for the prefabricated base 1 and the muffler side wall 3, and utilizes the vibration of the muffler side wall 3 during operation to release the air-hardening gel material stored in the fixing plug 6, and fixes the fixing plug 6 to the prefabricated base 2, thereby increasing the fixing effect of the muffler side wall 3, making the assembly structure of the muffler side wall 3 and the muffler top plate 4 less likely to collapse, and increasing the overall stability of the noise reduction and muffler structure of the water pump body 1

[0041] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
