Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, specifically to a box-type negative pressure-free water supply equipment. Background Technology

[0002] Box-type negative pressure-free water supply equipment is a new type of water supply device used in urban water supply, building secondary water supply, and other scenarios. It combines the advantages of traditional water tank storage and negative pressure-free variable frequency water supply technology, and is mainly used to solve problems such as insufficient pressure in municipal pipe networks and unstable water supply during peak water usage periods. Among them, the water tank is the basic part of the box-type negative pressure-free water supply equipment, which stores water from the municipal pipe network as a water supply buffer reserve to cope with peak water usage or pipe network outages.

[0003] Because the water tank of the box-type negative pressure water supply equipment is large in size and is made of stainless steel welded to form an integral structure, it also leads to the need to install many support rods inside the water tank to maintain its stability. In addition, since the water tank also needs to install baffles, level gauges and other components, the inside of the water tank becomes messy and disorderly.

[0004] Furthermore, when the water circulation inside the tank is poor, "dead water areas" can easily form, leading to the proliferation of microorganisms. This is especially true in the high temperatures of summer, which accelerates the deterioration of water quality. Also, due to the limited space inside the tank, manual cleaning is insufficient to thoroughly remove the sediment and rust deposits in the corners.

[0005] Therefore, it is necessary to invent a box-type negative pressure-free water supply device to solve the above problems. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The box-type negative pressure-free water supply equipment shown includes a water tank 1. The water tank 1 is composed of several side plates 12, several top plates 11 and a bottom plate. Several side plates 12 in the same vertical direction form a group. Support components 3 are provided around the outside of the water tank 1. A suspension component 4 is provided above the top of the water tank 1.

[0029] In this embodiment, the water tank is welded from multiple stainless steel side plates 12 and a top plate 11. Side plates 12 in the same vertical direction form a group, creating a cubic frame. Both the side plates 12 and the top plate 11 are made of stainless steel, which is corrosion-resistant and has high strength. The welding process ensures airtightness. The stainless steel material and welding process enhance the overall rigidity of the water tank, resisting water pressure and external impacts. By replacing the internal support with an external support component 3, the internal space of the water tank 1 is freed up. Consequently, there are no unnecessary rods obstructing the water flow inside the water tank 1, resulting in smoother water circulation and reducing the risk of microbial growth. Furthermore, when the internal structure of the water tank 1 is not complex, it can be fully covered during manual or mechanical cleaning, preventing the accumulation of mud, sand, and rust in corners.

[0030] Support component 3 includes:

[0031] Several support rods 31 are vertically installed on the outside of each corresponding side plate 12. Several connecting parts 32 are fixedly installed on the back of each support rod 31, and each connecting part 32 corresponds to a side plate 12.

[0032] Suspension assembly 4 includes:

[0033] Several horizontal frames 41 are evenly spaced on the top of the water tank 1. Each horizontal frame 41 is evenly provided with several hooks 44, and each hook 44 corresponds to a top plate 11.

[0034] Furthermore, in the above technical solution, a protrusion 13 is fixedly installed on the outer middle part of each side plate 12, and threads are provided on the outer walls of both the connecting part 32 and the protrusion 13. A nut 33 is provided between the connecting part 32 and the protrusion 13, and the two ends of the nut 33 are connected to the connecting part 32 and the protrusion 13 respectively.

[0035] In this embodiment, the bottom of the support rod 31 is fixed to the ground with expansion bolts. The support rod 31 and the connecting part 32 replace the traditional internal support components of the water tank 1, avoiding the rod from occupying the internal volume of the water tank 1, while enhancing the water pressure resistance of the side plate, especially for high-water-level water tanks 1. The connecting part 32 is connected to the protrusion 13 by the nut 33, thereby allowing for fine adjustment of the distance between the support rod 31 and the side plate 12, adapting to water tanks of different sizes or installation errors, and improving assembly efficiency. Moreover, this threaded connection provides reliable mechanical fastening force, preventing the support rod 31 from loosening, which is especially suitable for vibrating environments such as when a water pump is running.

[0036] Furthermore, in the above technical solution, a pull ring 14 is movably installed on the top of each top plate 11, each hook 44 corresponds to a pull ring 14, each hook 44 is connected to the corresponding pull ring 14, and a limit ring 45 is threadedly installed on the upper end of the hook 44, the limit ring 45 is located above the crossbeam 41.

[0037] Furthermore, in the above technical solution, the cross frame 41 has a U-shaped structure, and grooves 42 are provided at the bottom of both ends of the cross frame 41. The grooves 42 are adapted to the top of the support rods 31, and the tops of two symmetrical support rods 31 are respectively sleeved at both ends of the cross frame 41.

[0038] In this embodiment, the bottom ends of the crossbeams 41 are provided with grooves 42 that fit the tops of the support rods, allowing them to be directly fitted onto the tops of the support rods 31. Since the crossbeams 41 are evenly distributed on the top of the water tank 1, they form a suspended support network. The engagement of the grooves 42 with the tops of the support rods 31 allows for installation of the crossbeams 41 without additional tools, shortening the construction period. Furthermore, the even distribution of multiple crossbeams distributes the pressure on the top of the water tank 1, such as the weight of personnel during maintenance or additional equipment, to the surrounding support rods, preventing localized deformation of the top plate 11. The lower end of the hook 44 hooks onto the corresponding pull ring 14 of the top plate 11. The combination of the hook 44 and the pull ring 14 allows for quick fixation of the top plate 11, while the limiting ring 45 prevents the hook 44 from falling off.

[0039] Furthermore, in the above technical solution, the crossbar 41 is vertically provided with a plurality of evenly distributed through holes 43, the hook 44 corresponds to the through holes 43, the upper end of the hook 44 passes through the through hole 43, and a ladder 2 is fixedly installed on one side of the outer wall of the water tank 1.

[0040] Furthermore, in the above technical solution, the top plate 11 and the side plate 12 are both made of stainless steel, and several side plates 12 around the water tank 1 are welded together, and several top plates 11 on the top of the water tank 1 are welded together.

[0041] In this embodiment, the external support rod 31 and the top crossbeam 41 form a three-dimensional support frame, replacing the traditional internal support structure of the water tank. The water pressure on the side plate 12 is transmitted to the support rod 31 through the protrusion 13, and then distributed to the entire frame through the crossbeam 41, preventing the side plate 12 from bulging or cracking. The suspension assembly 4 rigidly connects the top plate 11 to the support rod 31, preventing the top plate 11 from sagging due to gravity or external forces, and improving the overall deformation resistance of the water tank 1. Since there are no support rods, guide plates, or other components inside the water tank, a high-pressure water gun can be used for thorough cleaning.

[0042] The working process of the box-type negative pressure-free water supply equipment provided by this utility model is as follows:

[0043] Close the inlet valve and start the variable frequency pump to lower the water level in the tank to the low level. Reach the top of the tank via ladder 2, unscrew the limit ring 45, remove the hook 44, and move the movable top plate 11 to expose the interior of tank 1. Then, staff enter the tank with cleaning tools. High-pressure water guns are used to rinse the tank walls and bottom, focusing on cleaning the corners where there are no internal support rods, allowing for complete coverage of sediment. Brushes are then used with disinfectant such as sodium hypochlorite to scrub the tank walls, removing biofilm and rust. After cleaning, the drain valve at the bottom of tank 1 is opened to discharge wastewater and impurities.

[0044] After cleaning, reset the top plate 11, connect it to the pull ring 14 using the hook 44, and tighten the limit ring 45. Open the water inlet valve and fill the water tank 1 to full. Check for leaks at the connection of the top plate 11. If the water tank 1 is deformed or installation errors cause uneven stress on the support rod 31, loosen the nut 33, fine-tune the relative position of the connecting part 32 and the protrusion 13, and then tighten it again. The spacing of the hooks 44 can be adjusted through the crossbeam through hole 43 to accommodate different sizes of top plates 11 or to cope with local load changes.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
