Description
Technical Field
[0001] This utility model relates to the field of water supply equipment technology, and in particular to a tap water supply device without negative pressure. Background Technology
[0002] Currently, traditional tap water supply systems without loads generally suffer from numerous problems during operation. The continuous vibrations exacerbate friction and collisions between mechanical parts, accelerating wear and tear, reducing equipment lifespan, and significantly increasing maintenance and replacement costs. Furthermore, the operating noise pollutes the surrounding environment. In addition, the lack of effective protective measures during equipment maintenance poses safety hazards. Existing water supply systems also lack functional integration and intelligence, making it difficult to meet the requirements of modern water supply systems for high efficiency, stability, and safety.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: because the traditional water supply device body will continuously generate vibration during operation, this phenomenon will aggravate the friction and collision of mechanical parts connection parts. With the accumulation of time, this high-frequency vibration will accelerate the wear of parts, significantly shorten the service life of the water supply device body, greatly increase the later maintenance and replacement costs, and bring a heavy burden to the long-term stable operation and maintenance of the equipment; therefore, a non-burdened tap water supply device is proposed to address the above problems. Summary of the Invention
[0004] The purpose of this utility model is to solve the problem that in the existing technology, the traditional water supply device body will continuously generate vibration during operation. This phenomenon will aggravate the friction and collision of mechanical parts connection parts. With the accumulation of time, this high-frequency vibration will accelerate the wear of parts, significantly shorten the service life of the water supply device body, greatly increase the later maintenance and replacement costs, and bring a heavy burden to the long-term stable operation and maintenance of the equipment. Therefore, a non-burdened tap water supply device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tap water supply device without negative pressure, comprising a water supply device, wherein the surface of the water supply device body is provided with a shock-absorbing device, the shock-absorbing device comprising two connecting plates, both of which are fixedly connected to the surface of the water supply device body, and a circular chamber is fixedly connected to the surface of each of the two connecting plates, a circular rod is slidably connected to the inner surface of the circular chamber, a U-shaped frame is fixedly connected to the surface of the circular rod, and a spring is sleeved on the arc surface of the circular chamber, the two ends of the spring being fixedly connected to the connecting plate and the U-shaped frame respectively.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a shock-absorbing device, the shock absorption effect of the water supply device body during operation is achieved, avoiding the continuous vibration generated by the traditional water supply device body during operation. This phenomenon will aggravate the friction and collision of mechanical parts connection parts. With the accumulation of time, this high-frequency vibration will accelerate the wear of parts, significantly shorten the service life of the water supply device body, greatly increase the later maintenance and replacement costs, and bring a heavy burden to the long-term stable operation and maintenance of the equipment.
[0007] Preferably, two screws are threaded into the connecting plate, and a hexagonal shank is fixedly connected to the surface of each screw. Four screw grooves are opened on the surface of the water supply device body, and the screws are threaded to the inner wall of the screw grooves of the water supply device body.
[0008] The effect achieved by the above components is that the screw and hexagonal shank are connected to the water supply device body by threads. When installing the connecting plate, it is only necessary to screw it into the corresponding threaded hole on the water supply device body to complete the connection, thereby reducing the installation difficulty and improving the installation efficiency.
[0009] Preferably, the surface of the U-shaped frame is fixedly connected with sound insulation cotton, and the size of the round rod is adapted to the size of the inner surface of the round chamber.
[0010] The effect achieved by the above components is as follows: the sound insulation cotton has a porous structure. When the noise generated by the water supply device is in operation, it will be reflected and refracted in these pores, thus consuming energy and converting it into heat energy to dissipate, thereby reducing the spread of noise to the surrounding environment.
[0011] Preferably, a rubber block is fixedly connected to the surface of the sound insulation cotton, and the rubber block is made of rubber.
[0012] The effect achieved by the above components is as follows: the water pump in the water supply device body will generate vibration and noise during operation. The rubber block is installed between the base and the foundation ground. Through the elastic deformation of the rubber block, it can absorb vibration energy and reduce the transmission of vibration to the surrounding structure, thereby reducing the noise and vibration generated during the operation of the equipment.
[0013] Preferably, the surface of the water supply device body is provided with a protective device, which includes four elliptical plates. The four elliptical plates are fixedly connected to the surface of the water supply device body. The four elliptical plates are arranged in pairs. A long rod is fixedly connected to the side of each pair of elliptical plates that is close to each other. A protective plate is rotatably connected to the arc surface of the long rod. Two threaded grooves are opened on the surface of the protective plate. A threaded rod is inserted into the inner thread of the elliptical plate. The threaded rod is threadedly connected to the inner wall of the threaded groove of the protective plate.
[0014] The aforementioned components achieve the following effect: by setting up protective devices, they effectively prevent personnel from passing by when workers are repairing the water supply device. When workers are performing maintenance work on the water supply device, a physical barrier is formed to effectively prevent passing personnel from accidentally entering the maintenance area. This not only creates a safe and independent working space for maintenance work, but also significantly reduces the safety risks caused by personnel accidentally entering, effectively ensuring the personal safety of workers and the smooth progress of maintenance work.
[0015] Preferably, the arc surface of the long rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the elliptical plate and the protective plate, respectively.
[0016] The effect achieved by the above components is that when the limit on the protective plate is released, the torsion spring releases elastic potential energy, generates torque, and drives the protective plate to rotate around the long rod, so that the protective plate can be quickly reset without direct manual operation, thus improving the convenience and automation of operation.
[0017] Preferably, two baffle plates are fixedly connected to the surface of the water supply device body, and the size of the threaded rod is adapted to the size of the threaded groove of the protective plate.
[0018] The purpose of the above components is to prevent the protective plate from rigidly colliding with the precision equipment of the water supply device body during the resetting process.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting a shock-absorbing device, the shock absorption effect of the water supply device body during operation is achieved, avoiding the continuous vibration generated by the traditional water supply device body during operation. This phenomenon will aggravate the friction and collision of mechanical parts connection parts. With the accumulation of time, this high-frequency vibration will accelerate the wear of parts, significantly shorten the service life of the water supply device body, greatly increase the later maintenance and replacement costs, and bring a heavy burden to the long-term stable operation and maintenance of the equipment.
[0021] 2. In this utility model, by setting up a protective device, the effect of intercepting passersby when workers are repairing the water supply device is achieved. When workers are carrying out maintenance work on the water supply device, a physical barrier can be formed to effectively intercept passersby and prevent them from accidentally entering the maintenance area. This not only creates a safe and independent working space for maintenance work, but also significantly reduces the safety risks caused by people accidentally entering, and effectively protects the personal safety of workers and the smooth progress of maintenance work.

Detailed Implementation
[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a tap water supply device without negative pressure, including a water supply device. The surface of the water supply device body 1 is provided with a shock-absorbing device 2. By setting the shock-absorbing device 2, the shock absorption effect of the water supply device body 1 during operation is achieved, avoiding the continuous vibration generated by the traditional water supply device body 1 during operation. This phenomenon will aggravate the friction and collision of the mechanical parts connection parts. With the accumulation of time, this high-frequency vibration will accelerate the wear of the parts, significantly shorten the service life of the water supply device body 1, greatly increase the later maintenance and replacement costs, and bring a heavy burden to the long-term stable operation and maintenance of the equipment. The surface of the water supply device body 1 is provided with a protective device 3. By setting the protective device 3, the effect of intercepting passers-by when the water supply device body 1 is being repaired is achieved. When the water supply device body 1 is being repaired, a physical barrier can be formed to effectively intercept passers-by and prevent them from accidentally entering the repair area. This not only creates a safe and independent working space for the repair work, but also significantly reduces the safety risks caused by personnel accidentally entering, effectively ensuring the personal safety of the operators and the smooth progress of the repair work.
[0028] The following section will explain the specific setup and function of its shock absorption device 2 and protective device 3.
[0029] Reference Figure 2As shown in this embodiment: the shock absorption device 2 includes two connecting plates 21, both of which are fixedly connected to the surface of the water supply device body 1. A circular chamber 22 is fixedly connected to the surface of each connecting plate 21. A circular rod 23 is slidably connected to the inner surface of the circular chamber 22. A U-shaped frame 24 is fixedly connected to the surface of the circular rod 23. A spring 25 is fitted onto the arc surface of the circular chamber 22. The two ends of the spring 25 are fixedly connected to the connecting plate 21 and the U-shaped frame 24, respectively. Two screws 26 are threaded into the connecting plate 21. A hexagonal shank 27 is fixedly connected to the surface of each screw 26. Four threaded grooves are formed on the surface of the water supply device body 1. The screws 26 are threadedly connected to the inner walls of the threaded grooves of the water supply device body 1. The screws 26 and the hexagonal shank 27 are threadedly connected to the water supply device body 1. When installing the connecting plate 21, it is only necessary to screw it into the corresponding threaded hole on the water supply device body 1. This allows for easy connection, reducing installation difficulty and improving efficiency. Sound insulation cotton 28 is fixedly connected to the surface of the U-shaped frame 24. The dimensions of the round rod 23 are matched to the dimensions of the inner surface of the round chamber 22. The sound insulation cotton 28 has a porous structure. When noise generated during the operation of the water supply device 1 reaches the sound insulation cotton 28, the sound waves are continuously reflected and refracted in these pores, consuming energy and converting it into heat energy, thus reducing the transmission of noise to the surrounding environment. Rubber blocks 29 are fixedly connected to the surface of the sound insulation cotton 28. The rubber blocks 29 are made of rubber. During operation, the water pump in the water supply device 1 generates vibration and noise. The rubber blocks 29 are installed between the base and the foundation ground. Through the elastic deformation of the rubber blocks 29, vibration energy can be absorbed, reducing the transmission of vibration to the surrounding structure, thereby reducing the noise and vibration generated during equipment operation.
[0030] Reference Figure 3 and Figure 4As shown, specifically, the protective device 3 includes four elliptical plates 31, all of which are fixedly connected to the surface of the water supply device body 1. The four elliptical plates 31 are arranged in pairs, and a long rod 32 is fixedly connected to the side of each pair of elliptical plates 31 that is close to each other. A protective plate 33 is rotatably connected to the arc surface of the long rod 32. Two threaded grooves are opened on the surface of the protective plate 33. A threaded rod 34 is inserted into the thread of the elliptical plate 31, and the threaded rod 34 is threadedly connected to the inner wall of the threaded groove of the protective plate 33. Two torsion springs 35 are sleeved on the arc surface of the long rod 32, and the two ends of the torsion springs 35 are respectively connected to the elliptical plate 31 and the protective plate. The protective plate 33 is fixedly connected. When the limit on the protective plate 33 is released, the torsion spring 35 will release elastic potential energy and generate torque, driving the protective plate 33 to rotate around the long rod 32. This allows the protective plate 33 to be quickly reset without direct manual operation, improving the convenience and automation of operation. Two blocking plates 36 are fixedly connected to the surface of the water supply device body 1. The size of the threaded rod 34 is adapted to the size of the threaded groove of the protective plate 33. The purpose of setting the blocking plates 36 is to prevent the protective plate 33 from rigidly colliding with the precision equipment of the water supply device body 1 during the reset process.
[0031] Working principle: During operation, the water supply device body 1 generates vibration and noise. First, the water supply device body 1 moves the connecting plate 21 downwards, which in turn moves the cylindrical chamber 22 downwards. The cylindrical chamber 22 slides on the arc surface of the cylindrical rod 23, compressing the spring 25. The spring 25 absorbs and dissipates this vibration energy through elastic deformation, thereby reducing the vibration transmitted to the ground. However, the sound-insulating cotton 28 on the surface of the U-shaped frame 24 has a porous structure. When the noise generated by the water supply device body 1 propagates to the sound-insulating cotton 28, the sound waves are continuously reflected and refracted in these pores, thus consuming energy and converting it into heat energy, thereby reducing the propagation of noise to the surrounding environment. (Rubber...) Block 29 is installed between the base and the foundation ground. Through the elastic deformation of the rubber block 29, it can absorb vibration energy and reduce the transmission of vibration to the surrounding structure, thereby reducing the noise and vibration generated during equipment operation. By setting up the protective device 3, it achieves the effect of intercepting passersby when workers are repairing the water supply device body 1. When workers are carrying out maintenance work on the water supply device body 1, it can form a physical barrier to effectively intercept passersby and prevent them from accidentally entering the maintenance area. This not only creates a safe and independent working space for maintenance work, but also significantly reduces the safety risks caused by personnel accidentally entering, and effectively protects the personal safety of workers and the smooth progress of maintenance work.
[0032] When staff need to maintain the water supply device body 1, they first rotate the threaded rod 34 backward until it disengages from the threaded groove of the protective plate 33, thus releasing the restriction on the protective plate 33. When the restriction is released, the torsion spring 35 releases its elastic potential energy, generating torque to drive the protective plate 33 to rotate around the long rod 32. This allows the protective plate 33 to quickly reset without direct manual operation, thereby improving the convenience and automation of operation. By setting the shock absorption device 2, the shock absorption effect of the water supply device body 1 during operation is achieved, avoiding the continuous vibration generated by the traditional water supply device body 1 during operation. This phenomenon would exacerbate the friction and collision at the connection points of mechanical parts. With long-term accumulation, this high-frequency vibration would accelerate the wear of parts, significantly shorten the service life of the water supply device body 1, greatly increase the cost of later maintenance and replacement, and place a heavy burden on the long-term stable operation and maintenance of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
