Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption of water supply equipment, in particular to non-negative pressure water supply equipment with a shock absorption protection device. Background Art

[0002] A non-negative pressure water supply system is a pressurized water supply unit that can be directly connected to the municipal water supply network. It utilizes the residual pressure of the municipal water supply network to provide a series superimposed pressure supply, ensuring that the municipal water supply pressure is always maintained above the set protection pressure, which is usually no less than 1.2 kg. Its core function is to prevent the generation of negative pressure during the operation of the secondary pressurized water supply system, thereby reducing the impact on the municipal water supply network and achieving safe, reliable, and stable water supply.

[0003] When discussing the problems of non-negative pressure water supply equipment, we need to conduct an in-depth analysis of the limited effect of the shock-absorbing equipment at the water supply tank and the water outlet of the tank body, and the high degree of spring damage at the base of the equipment.

[0004] First, regarding the limited effectiveness of vibration damping devices at the water supply tank and tank outlet, we recognize that the primary function of vibration damping devices is to reduce vibration and noise during operation, improving equipment stability and extending service life. However, due to the complex vibration characteristics of the water supply tank and tank outlet, a single vibration damping device may not be able to completely eliminate vibration. Therefore, we need to optimize the selection of vibration damping devices, considering increasing the number of vibration damping devices or adjusting their installation location to further enhance the vibration reduction effect.

[0005] Secondly, regarding the high level of spring damage at the equipment base, we understand that springs, as important shock-absorbing components, are subject to significant vibration and impact during operation. Spring damage can result from defects in material, design, or manufacturing processes, as well as from harsh operating environments, uneven stress, overload, and other factors during equipment operation. Utility Model Content

[0006] The main purpose of the utility model is to provide a non-negative pressure water supply equipment with a shock-absorbing protection device, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A non-negative pressure water supply device with a shock-absorbing protective device includes a mounting plate, mounting holes, a support frame, a non-negative pressure water supply tank, and a water supply pipe. A plurality of the mounting holes are provided on the mounting plate. The non-negative pressure water supply tank is mounted on the mounting plate via the support frame. The water supply pipe is connected to the non-negative pressure water supply tank and is mounted on the mounting plate via bolts.

[0009] The two mounting plates are arranged in parallel and are divided into an upper plate and a lower plate. A plug rod is inserted into the mounting hole of the upper plate, and a limiting sleeve is provided on the upper end of the plug rod to limit it to the upper plate.

The circular tube at the lower end of the limiting base passes through the mounting hole to be connected to the limiting base, and the limiting base, the limiting base and the insertion rod squeeze each other, and the buffering between the insertion rod and the limiting base is achieved through the multiple layers of buffer washers.

[0011] Among them, side strips are provided between the two mounting plates, and multiple side strips are distributed around the upper plate and the lower plate. Buffer rubber strips are provided between the side strips and the upper plate and the lower plate to limit the range of movement of the upper plate and the lower plate.

[0012] The insertion rod is divided into a screw rod and a limiting ring. The limiting ring is located at the lower end of the screw rod. The cross section of the insertion rod is designed in a "T" shape. The limiting sleeve is threadedly connected to the insertion rod.

This design significantly enhances the structural stability of the entire water supply equipment and reduces the risk of equipment damage or performance degradation caused by vibration.

[0018] By utilizing a multi-layer cushioning washer design, the shock-absorbing base provides greater vibration absorption space, allowing vibration to be transmitted and dispersed layer by layer between the multiple layers of material.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0028] like Figures 1 to 5As shown, this embodiment provides a non-negative pressure water supply device with a shock-absorbing protective device. The device mainly includes a shock-absorbing base 1, a support frame 2, a non-negative pressure water supply tank 3, and a water supply pipe 4. Among them, the shock-absorbing base 1 is a key component. Its sophisticated design can effectively absorb and disperse the vibration generated by the device during operation, thereby ensuring the stable operation of the water supply device.

[0029] The shock-absorbing base 1 consists of a mounting plate 11, a rod 13, and a restraining base 15. The mounting plate 11 serves as the foundation for the entire base and is provided with multiple mounting holes 12 for convenient connection to the support frame 2 and other components. The support frame 2 supports the non-negative pressure water supply tank 3, ensuring its secure attachment to the mounting plate 11.

[0030] The combination of the insertion rod 13 and the limiting base 15 is the core component of the shock-absorbing base 1. The insertion rod 13 is inserted into the mounting hole 12 of the upper plate and secured by a limiting sleeve 14 to prevent it from falling out. The limiting base 15 is inserted into the mounting hole 12 of the lower plate. A blind hole 16 at its upper end accommodates the insertion of the insertion rod 13. This double-layer design increases structural stability and provides greater shock absorption space.

[0031] Multiple buffer washers 18 are connected to the bottom of the blind hole 16. These buffer washers 18 are made of a special material with excellent elasticity and durability. Each buffer washer 18 has multiple hexagonal holes 19 at its upper end and multiple hexagonal columns 10 at its lower end. This design ensures that adjacent buffer washers 18 are stably connected through the staggered fit of the hexagonal columns 10 and hexagonal holes 19. When the rod 13 is subjected to vibration, the multiple layers of buffer washers 18 absorb and disperse the impact force layer by layer, effectively reducing the impact of vibration on the water supply equipment.

[0032] The lower end of the circular tube of the limiting base 15 passes through the mounting hole 12 and connects to the limiting base 01. The limiting base 01, limiting base 15, and insertion rod 13 squeeze each other, forming a tight, shock-absorbing structure. This structure not only withstands large impact forces but also maintains long-term stability and durability.

[0033] In addition, the insert rod 13, the limiting sleeve 14, the limiting ring 17, and the limiting base 15 are all threaded, making them easy to disassemble and repair. At the same time, the multi-layer buffer washers 18 are bonded together to ensure the integrity and stability of the entire shock-absorbing structure. Example

[0034] like Figures 1 to 3 As shown, this embodiment provides another non-negative pressure water supply equipment with a shock-absorbing protection device, the structure of which is similar to that of the first embodiment, but different in details.

[0035] Similarly, the device includes a shock-absorbing base 1, a support frame 2, a non-negative pressure water supply tank 3, and a water supply pipe 4. The shock-absorbing base 1 is still composed of components such as a mounting plate 11, an insertion rod 13, and a limiting base 15, and adopts a similar double-layer design and a buffer gasket 18 structure.

[0036] However, in the second embodiment, side bars are added between the two mounting plates 11. These side bars are distributed around the upper and lower plates, and cushioning rubber strips are provided between them. This design further limits the range of motion of the upper and lower plates, enhancing the stability and reliability of the entire shock-absorbing structure.

[0037] Furthermore, in the second embodiment, the insert rod 13, limiting sleeve 14, limiting ring 17, and limiting base 15 utilize the same threaded connection method as in the first embodiment, facilitating disassembly and maintenance. Furthermore, the multiple layers of cushioning washers 18 are still bonded together, ensuring the integrity and stability of the entire shock-absorbing structure.

[0038] Comparing Example 1 and Example 2, we can see that the two examples are structurally similar, but differ in their detailed designs. Example 2 further enhances the stability and reliability of the shock-absorbing structure by adding side strips and rubber buffer strips. This design variation can be selected and applied based on actual needs to meet the shock absorption requirements of water supply equipment in different scenarios.

[0039] Working Process: The operation of the non-negative pressure water supply equipment's vibration reduction system relies primarily on the precise design of the vibration-reducing base 1 and the interaction between its components. When the water supply equipment is in operation, vibrations generated by factors such as the water flow and the motor are first transmitted to the mounting plate 11. The rods 13 on the mounting plate 11 then transfer these vibrations to the buffer washers 18.

[0040] The special material and structural design of the buffer washers 18 provide excellent elasticity and shock absorption capabilities. When the rod 13 is subjected to vibration, the buffer washers 18 deform, absorbing and dissipating the vibration force. Because the multiple buffer washers 18 are staggered and connected by hexagonal columns 10 and hexagonal holes 19, vibration is transmitted and dispersed layer by layer among the multiple buffer washers 18, significantly reducing the vibration force ultimately transmitted to the support frame 2 and the non-negative pressure water supply tank 3.

[0041] At the same time, the presence of the limiting base 15 and the limiting base 01 further enhances the shock absorption effect. The interaction between them and the insertion rod 13 forms a tight shock absorption structure, which can limit the excessive movement of the insertion rod 13 and maintain the stability of the entire shock absorption system.

[0042] When the water supply equipment operates for a long time or encounters large vibrations, the shock absorption system can continuously and effectively absorb and disperse the vibration force through the deformation and multi-layer dispersion effect of the buffer gasket 18, thereby ensuring the stable operation of the water supply equipment.

[0043] During installation: When installing the non-negative pressure water supply equipment shock absorption system, it is first necessary to fix the mounting plate 11 of the shock absorption base 1 in a suitable position. This usually involves drilling holes in the predetermined position and using bolts or other fasteners to fix the mounting plate 11 to the ground or foundation.

[0044] Next, the support frame 2 is placed on the mounting plate 11 and fixed by bolts or other connection methods. Ensure that the support frame 2 is stable and level so that the non-negative pressure water supply tank 3 can be installed later.

[0045] Then, insert the insertion rod 13 into the mounting hole 12 on the mounting plate 11 and fix it with the limiting sleeve 14. Make sure that the insertion rod 13 is vertical and stable without shaking or falling off.

[0046] Then, the limiting base 15 is inserted into the mounting hole 12 of the lower plate, and its position is guaranteed to be correct. At this moment, the top of the plunger 13 should be able to smoothly insert the blind hole 16 on the limiting base 15.

[0047] A buffer washer 18 is placed at the bottom of the blind hole 16. According to the design requirements, multiple buffer washers 18 are stacked layer by layer, and it is ensured that the hexagonal column 10 of each buffer washer 18 correctly corresponds to the hexagonal hole 19 of the next layer.

[0048] Finally, connect the limit base 01 to the lower end of the circular tube of the limit base 15. At this point, the entire shock absorption system has been assembled. Check that all connections are securely fastened and there is no looseness or shaking.

[0049] After completing the above steps, the non-negative pressure water supply tank 3 can be placed on the support frame 2 and connected to the water supply pipe 4. At this point, the non-negative pressure water supply equipment has been installed and equipped with an effective shock-absorbing protective device and can be put into use.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
