Description

Technical Field

[0001] This utility model relates to the field of hot water pump technology, specifically to a variable frequency booster hot water pump. Background Technology

[0002] Hot water pumps are essential equipment for extracting geothermal water and can also be used in pools, tanks, and for pressurization. Specifically, they can be used for underground water extraction in hotel hot springs and community heating. However, installing a hot water pump requires drilling holes in the wall, which damages the wall surface and is unsightly. This not only increases installation costs but also makes disassembly time-consuming and labor-intensive. Furthermore, the vibration generated during operation can easily cause the hot water pump to fall.

[0003] A search revealed a prior art hot water pump with a variable frequency booster structure (publication number: CN213016753U). The document describes that "a sound-absorbing plate is installed inside the mounting housing. Multiple heat dissipation holes are provided on both the left and right sides of the mounting housing and the sound-absorbing plate. The connection of these heat dissipation holes on the mounting housing and the sound-absorbing plate serves to dissipate heat from the hot water pump body. The hot water pump body is inserted into the inner side of the sound-absorbing plate. A gearbox is installed inside the hot water pump body. A controller is installed on the front side of the hot water pump body. A control button and a display screen are provided on the front side of the controller. The control button controls the operation of the gearbox and is electrically connected to the gearbox through the controller. The gearbox can change the operating speed of the hot water pump body, thereby regulating the water pressure in the water pipe. The display screen can display the water pressure in numerical form. An inlet pipe is provided on the upper right side of the hot water pump body, and an outlet pipe is provided on the upper left side of the hot water pump body." A mounting plate is detachably and fixedly connected to the rear side of the mounting housing. A support arm is fixedly connected to the rear side of the mounting plate. A retaining ring is fixedly connected to the rear end of the support arm. Two limiting sleeves are adhered to the outer side of the water supply pipe. Each of the two limiting sleeves has a limiting groove on its outer side. The two retaining rings are respectively engaged with the limiting grooves on the two limiting sleeves. This hot water pump achieves the purpose of limiting and fixing the retaining ring by setting limiting sleeves on the outer side of the water supply pipe, preventing the hot water pump body from falling off due to vibration, thus ensuring the safety of the hot water pump body. A sound-absorbing plate is installed inside the mounting housing to reduce the noise generated by the hot water pump body. However, this hot water pump only reduces noise through the sound-absorbing plate and cannot buffer and dampen the vibration generated during operation. Consequently, the hot water pump easily drives the mounting housing and other related structures to vibrate synchronously, thereby reducing the noise reduction effect of the sound-absorbing plate and making the hot water pump prone to noise pollution during operation. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a variable frequency booster hot water pump is provided to solve the problems mentioned in the background art.

[0009] Preferably, there are two sets of airbags, both sets of airbags are rectangular in structure, and the upper surfaces of the two sets of airbags do not contact the lower surface of the buffer shell.

At the same time, the outer side of the buffer shell abuts against the surface of the buffer layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the buffer layer, buffer rod, spring, vertical sliding plate, horizontal sliding plate and airbag, the mounting shell and buffer shell can have a good shock absorption structure, which can effectively reduce the vibration intensity of the mounting shell and mounting components, thereby effectively reducing the noise generated by vibration during the operation of the variable frequency booster pump body.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a variable frequency booster hot water pump, including: a mounting shell 3, the mounting shell 3 is fixedly connected to a water supply pipe 15 through a mounting assembly 14, and the variable frequency booster pump body 1 is fixedly connected to a buffer shell 4 through a reinforcing plate 16. Airbags 11 are symmetrically connected to the bottom of the inner cavity of the mounting shell 3, and guide holes are opened at the bottom and both sides of the inner cavity of the mounting plate. Friction sleeves 13 are fixedly connected in the guide holes, and a horizontal sliding groove 9 is opened on the lower surface of the buffer shell 4 relative to the position of the guide hole. A vertical sliding groove 7 is opened on the side of the buffer shell 4 relative to the position of the guide hole. A vertical sliding plate 6 and a horizontal sliding plate 10 are slidably connected in the vertical sliding groove 7 and the horizontal sliding groove 9, respectively. At the same time, a buffer rod 5 is fixedly connected to the surface of the vertical sliding plate 6 and the horizontal sliding plate 10 relative to the position of the guide hole. A spring is sleeved on the surface of the buffer rod 5, and a sealing assembly 2 is symmetrically connected to the upper ends of both sides of the inner cavity of the mounting shell 3, and a buffer layer 12 is symmetrically connected to both ends of the inner cavity of the mounting frame.

[0019] In this embodiment, the mounting housing 3 is fixedly connected to the water supply pipe 15 via the mounting assembly 14, and the variable frequency booster pump body 1 is fixedly connected to the buffer housing 4 via the reinforcing plate 16, thus completing the installation of the variable frequency booster hot water pump. The variable frequency gearbox (not shown in the figure) inside the variable frequency booster pump body 1 is adjusted by the controller set on the surface of the housing, thereby achieving the variable frequency boosting effect of the variable frequency booster pump body 1. When the variable frequency booster hot water pump vibrates during operation, the variable frequency booster pump body 1 will drive the buffer housing 4 to vibrate synchronously via the reinforcing plate 16. During the vibration, the buffer housing 4 will squeeze the corresponding buffer via the vertical sliding plate 6 or the horizontal sliding plate 10. The spring sleeved on rod 5 effectively weakens the impact of the vibration of buffer shell 4 on mounting shell 3. The friction sleeve 13 fixedly connected to the outer side of mounting shell 3 can effectively increase the frictional resistance when buffer rod 5 moves, thereby ensuring that buffer shell 4 can quickly recover stability after the variable frequency booster pump body 1 stops running. At the same time, the setting of buffer layer 12 and air bag 11 can help enhance the shock absorption effect of buffer shell 4 inside mounting shell 3. Furthermore, buffer layer 12, sealing component 2 and air bag 11 can work with sound insulation plate 8 to enhance the noise reduction effect of variable frequency booster hot water pump, reducing the probability of noise pollution when the variable frequency booster pump body 1 is running.

[0020] Meanwhile, the installation structure and working principle of the relevant components of the variable frequency booster pump body 1 and the mounting assembly 14 in this application are existing mature technologies, which have been fully disclosed in a hot water pump with a variable frequency booster structure (publication number: CN213016753U), and the variable frequency booster pump body 1 can also adopt common brand models on the market.

[0021] As a preferred embodiment, the buffer shell 4 has a U-shaped cross section. Two sets of vertical sliding grooves 7 are symmetrically opened on both sides of the buffer shell 4 along the width direction, and three sets of horizontal sliding grooves 9 are equally spaced on the lower surface of the buffer shell 4 along the width direction. At the same time, the adjacent vertical sliding grooves 7 and horizontal sliding grooves 9 are staggered.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The buffer housing 4 ensures that the vibration generated by the variable frequency booster pump body 1 will not directly act on the mounting housing 3, thereby helping to reduce the vibration intensity of the mounting housing 3 and the intensity of noise generated by the vibration of the mounting housing 3. At the same time, the position setting of the vertical slide groove 7 and the horizontal slide groove 9 ensures that the vertical slide plate 6 and the horizontal slide plate 10 can be smoothly slidably connected to the outer side of the buffer housing 4.

[0023] In a preferred embodiment, both the vertical slide plate 6 and the horizontal slide plate 10 are rectangular in shape, and the end faces of both the vertical slide plate 6 and the horizontal slide plate 10 are isosceles trapezoidal in shape. The dimensions of the vertical slide plate 6 and the vertical slide groove 7 are matched, and the dimensions of the horizontal slide plate 10 and the horizontal slide groove 9 are matched.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structural arrangement of the vertical slide plate 6 and the vertical slide groove 7 with the horizontal slide plate 10 and the horizontal slide groove 9 can effectively enhance the stability of the connection between the vertical slide plate 6 and the horizontal slide plate 10 and the buffer shell 4, ensuring that the vertical slide plate 6 and the horizontal slide plate 10 can move along a specific path, thereby helping to enhance the buffer shell 4's damping effect on vibration.

[0025] In a preferred embodiment, three sets of buffer rods 5 are fixedly connected to the surfaces of the vertical slide plate 6 and the horizontal slide plate 10 at equal intervals along the length direction, and the buffer rods 5 are cylindrical in shape. The vertical slide plate 6 and the horizontal slide plate 10 are combined with the corresponding buffer rods 5 to form an E-shaped structure.

[0026] In this embodiment, as Figure 1 and Figure 2 The guide rod can help enhance the stability of the vertical slide plate 6 and the horizontal slide plate 10 when they move on a specific moving path. It can also ensure that the buffer shell 4 is stably suspended in the mounting frame, thereby reducing the intensity of the vibration transmitted from the buffer shell 4 to the surface of the mounting shell 3, and thus helping to reduce the noise generated by the vibration.

[0027] As a preferred embodiment, there are two sets of airbags 11. Both sets of airbags 11 are rectangular in structure, and the upper surfaces of the two sets of airbags 11 do not contact the lower surface of the buffer shell 4. Meanwhile, the friction sleeves 13 fixedly connected to the outer side of the mounting shell 3 in the through hole are both annular in structure, and the inner cavity of the friction sleeve 13 abuts against the surface of the buffer rod 5.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The airbag 11 helps to enhance the damping effect of the mounting shell 3 on the buffer shell 4 and the variable frequency booster pump body 1. At the same time, the friction sleeve 13 is made of soft rubber, which helps to enhance the frictional resistance when the buffer rod 5 moves, so that the buffer rod 5 and the buffer shell 4 can quickly restore stability when no external force is applied.

[0029] In a preferred embodiment, the sealing component 2 consists of a fixing plate 17 and a friction plate 18. The fixing plate 17 has a [-shaped structure and is fixedly connected to the upper end of the side of the inner cavity of the mounting frame by a snap fastener. The main body of the friction plate 18 has a convex shape, and the surface of the friction plate 18 is provided with a protrusion corresponding to the position of the vertical sliding groove 7. The protrusion of the friction plate 18 has a dovetail shape, and the friction plate 18 abuts against the outer side of the buffer shell 4.

[0030] In this embodiment, as Figure 1 and Figure 4 The friction plate 18 is made of soft rubber, which allows the sealing component 2 to both block the opening on the upper surface of the mounting shell 3 to prevent foreign objects from falling into the mounting shell 3, and to help enhance the auxiliary cushioning effect when the buffer shell 4 moves.

[0031] In a preferred embodiment, the buffer layer 12 fixedly connected to the inner cavity of the mounting shell 3 is rectangular in structure, and the surface of the buffer layer 12 is evenly provided with sound-absorbing holes. The front of the mounting shell 3, the buffer layer 12, the buffer shell 4 and the sound insulation plate 8 are all provided with through openings. The inner cavity surface of the buffer shell 4 is fixedly connected with the sound insulation plate 8, and the two sides of the inner cavity of the sound insulation plate 8 are symmetrically connected with reinforcing plates 16. At the same time, the outer side of the buffer shell 4 abuts against the surface of the buffer layer 12.

[0032] In this embodiment, as Figure 1 and Figure 3 The buffer layer 12 is made of hard rubber, which can help reduce the vibration intensity transmitted by the buffer shell 4. The sound-absorbing holes on the surface of the buffer layer 12 can help reduce noise. At the same time, the opening of the through-hole makes it easy for workers to operate the controller on the surface of the variable frequency booster pump body 1.

[0033] The variable frequency booster hot water pump of this utility model, through the cooperation of the mounting shell 3, buffer rod 5, friction sleeve 13, buffer layer 12, vertical slide plate 6, horizontal slide plate 10, buffer shell 4 and reinforcing plate 16, can effectively enhance the vibration reduction and noise reduction effect of the main body 1 of the variable frequency booster pump during use. By reducing the vibration intensity of the mounting shell 3 and mounting components 14, it can also help enhance the overall stability of the variable frequency booster hot water pump after installation.
