Description

Technical Field

[0001] This utility model relates to the field of water tank technology in the water supply industry, and in particular to a circular ribbed water tank. Background Technology

[0002] In the water supply industry, water tanks are crucial facilities for water storage, pressure regulation, and emergency water supply. They are typically used to supply water to multiple buildings simultaneously. After initial pressurization and delivery of tap water to buildings via the municipal pipe network, insufficient water pressure prevents delivery to higher floors. Therefore, secondary water supply systems, consisting of water tanks and pumps, are needed to repressurize the tap water. However, in the water tank sector, the vast majority of tanks on the market are square or rectangular bulge-type or ribbed-plate type.

[0003] Existing water tanks are typically ribbed tanks, which have a large surface area, making manual welding difficult. Furthermore, the internal bracing can easily create unsanitary areas, reducing the water quality inside the tank and making it unsuitable for providing domestic water to densely populated buildings. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of difficult welding and difficult internal cleaning of water tanks in the prior art, and to propose a circular ribbed water tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circular ribbed water tank includes a circular water tank with an annular ribbed layer on its outer surface. A top plate assembly is provided on the top of the circular water tank, and a manhole assembly is mounted on the top plate assembly. The annular ribbed layer is a continuous corrugated integral part. The manhole assembly includes an opening in the top of the circular water tank, a sealing cover is connected to the opening, concave frames are connected to both sides of the sealing cover, and a handle is fixedly connected to the top of the concave frames.

[0007] Preferably, the connecting part includes an upper rib plate and a lower rib plate, and a splicing beam connects the upper rib plate and the lower rib plate, and the splicing beam is connected to the outer surface of the circular water tank.

[0008] Preferably, the wavelength of the upper rib is greater than that of the lower rib, and the number of ribs in the upper rib is less than that in the lower rib. The troughs of the upper rib are arc-shaped, and the peaks of the lower rib are rounded at both ends.

[0009] Preferably, the inner wall of the opening and the bottom side of the sealing cap are both tapered.

[0010] Preferably, the opening is provided with a fixing groove, a locking block is rotatably connected in the fixing groove, two adjacent round rods are provided in the fixing groove, an L-shaped slider is slidably connected in the fixing groove, a rectangular sliding groove is opened in the L-shaped slider to slidably connect with the two round rods, a spring is connected to the surface of each of the two round rods, a push block one is connected to one end of the spring, the push block one is linearly slidably connected to the surface of the two round rods, a push block two is slidably connected to the surface of the two round rods, a round push rod is connected to one end of the push block two, and the round push rod extends through to the outside of the opening.

[0011] Preferably, the locking block is cross-shaped, the horizontal end of the L-shaped slider is pressed against one side of the cross-shaped locking block, and the concave frame is engaged with the cross-shaped locking block.

[0012] Preferably, the circular push rod has a hollow internal structure, and the push block one and push block two are located on both sides of the L-shaped slider.

[0013] Compared with the prior art, the present invention provides a circular ribbed water tank, which has the following advantages:

[0014] 1. This circular ribbed water tank improves the pressure-bearing capacity of the lower half of the circular water tank by setting a large number of ribs with short wavelengths in the high-pressure zone and setting a small number of ribs with long wavelengths in the low-pressure zone of the upper half of the circular water tank. This maintains the pressure-bearing capacity of the circular water tank while reducing the cost of manufacturing the circular water tank. It also helps to reduce the amount of welding work done by workers and increases the pressure-bearing capacity of the circular water tank.

[0015] 2. This circular ribbed water tank, when the worker simultaneously presses the circular push rod and pulls the handle, forms a combined locking action on the sealing cover, reducing the safety accidents caused by unknowingly opening the sealing cover. After the cleaning work is completed, the concave frame naturally falls back under the action of gravity and quickly engages with the cross-shaped locking block, thereby locking the sealing cover and reducing the safety hazards caused by workers forgetting to lock it.

[0027] Example 1:

[0028] Reference Figure 1-7A circular ribbed water tank includes a circular water tank 1. The circular water tank 1 has a small footprint for its capacity and strong resistance to deformation. The outer surface of the circular water tank 1 is provided with an annular ribbed layer 2. A top plate assembly is provided on the top of the circular water tank 1, and a manhole assembly 3 is mounted on the top plate assembly. The annular ribbed layer 2 is a continuous corrugated section. The inner wall of the circular water tank 11 is a complete surface, reducing sanitary dead corners. The continuous section includes an upper ribbed 4 and a lower ribbed 5. The wavelength of the upper ribbed 4 is greater than that of the lower ribbed 5, and the number of ribs in the upper ribbed 4 is less than the number of ribs in the lower ribbed 5. The troughs of the upper ribbed 4 are arc-shaped, and the peaks of the lower ribbed 5 are rounded at both ends. The angular and arc-shaped troughs can disperse stress, and the rounded corners at both ends of the wave crests can prevent excessive stress concentration at both ends of the wave crests. The upper rib plate 4 has a larger wavelength and fewer ribs, which can support the low water pressure in the upper half of the circular water tank 1, reducing the welding difficulty and material quantity for workers. The lower rib plate 5 has a smaller wavelength and more ribs, which can support the high water pressure in the lower half of the circular water tank 1, increasing the deformation resistance and water capacity of the circular water tank 1. The splicing beam 6 can increase the compressive strength between the upper rib plate 4 and the lower rib plate 5, and increase the overall pressure bearing capacity of the circular water tank 1. The upper rib plate 4 and the lower rib plate 5 are connected by a splicing beam 6, which is connected to the outer surface of the circular water tank 1. The manhole assembly 3 includes an opening 7 opened at the top of the circular water tank 1, a sealing cover 8 connected inside the opening 7, concave frames 10 connected on both sides of the sealing cover 8, and a handle 9 fixedly connected to the top of the concave frame 10.

[0029] The top plate assembly of the circular water tank 1 is located at the top of the water tank and is connected to the top of the upper rib plate 4 by sealing welding. This can prevent dust and impurities from falling into the circular water tank 1. The top of the top plate assembly is also equipped with lifting ears. The lifting ears can be welded or screwed onto the top plate assembly and connected to the top plate assembly. The lifting ears can facilitate the lifting and positioning of the circular water tank.

[0030] The inner wall of the opening 7 and the bottom side of the sealing cover 8 are both conical. When the sealing cover 8 is in contact with the inner wall of the locking block 12, the contact surface is conical, which allows the inner walls of the sealing cover 8 and the locking block 12 to be in close contact, maintaining the airtightness of the circular water tank 1. The opening 7 is provided with a fixing groove 11, and the locking block 12 is rotatably connected in the fixing groove 11. The locking block 12 is cross-shaped. The horizontal end of the L-shaped slider 14 is pressed against one side of the cross-shaped locking block 12. The concave frame 10 is engaged with the cross-shaped locking block 12. When the sealing cover 8 is in contact with the locking block 12, the concave frames 10 at both ends of the sealing cover 8 will press against one side of the cross-shaped locking block 12, causing the locking block 12 to rotate in the fixing groove 11. At a 90-degree angle, the other end of the cross-shaped locking block 12 pushes the L-shaped slider 14 upward on the vertical plane of the two round rods 13, and falls back under the action of gravity, pressing and contacting one side of the cross-shaped locking block 12 again. At this time, the concave frame 10 is fixed in the space formed by the cross-shaped locking block 12 and the inner wall of the fixing groove 11, thereby forming a fixing effect on the sealing cover 8 and an automatic locking effect on the opening 7. The fixing groove 11 is provided with two adjacent round rods 13, which can restrict the movement direction of the L-shaped locking block 12. The L-shaped slider 14 is slidably connected in the fixing groove 11, and the L-shaped slider 14 has a rectangular opening that is slidably connected to the two round rods 13. The slide groove 15 and the cross-shaped locking block 12 can push the horizontal end of the L-shaped slider 14, causing the L-shaped slider 14 to move upward along the vertical surface of the two round rods 13. Springs 16 are connected to the surfaces of both round rods 13. In their natural state, the springs 16 push push block 17 to tightly fit against the L-shaped slider 14, causing a squeezing force between the L-shaped slider 14 and push block 17 and push block 2 18. Push block 17 is connected to one end of the spring 16 and slides linearly with the surfaces of the two round rods 13. Push block 2 18 is slidably connected to the surfaces of the two round rods 13, and one end of push block 2 18 is connected to a round push rod 19. Rod 19 extends through the outside of opening 7. The inside of the round push rod 19 is hollow. Push block 17 and push block 2 18 are located on both sides of L-shaped slider 14. Maintenance workers can push the round push rod 19, causing push block 2 18 to squeeze L-shaped slider 14 and push block 17, while squeezing spring 16, causing it to move in the direction of spring 16. At this time, the horizontal end of L-shaped slider 14 separates from cross-shaped locking block 12, and workers can pull up handle 9 to separate concave frame 10 from cross-shaped locking block 12. This facilitates workers to quickly open opening 7 and carry out cleaning work, and prevents the safety hazard of workers forgetting to lock opening 7 after cleaning work.

[0031] Example 2:

[0032] Reference Figure 8The annular rib layer 2 is a continuous corrugated integral part, which can be made of food-grade stainless steel. The troughs of the annular rib layer 2 are welded to the outer surface of the circular water tank 1, and the annular rib layer 2 is arranged in a regular and orderly manner on the outer surface of the circular water tank 1. It can support the maximum amount of tap water that can be stored in a water bucket of the same material, and maximize the pressure bearing capacity of the circular water bucket while increasing the water storage capacity of the circular water tank 1. It also reduces the sanitary dead corners inside the circular water tank 1, making it convenient for workers to enter the circular water tank 1 for cleaning through the manhole assembly 3.

[0033] In this invention, the circular water tank 1 has the largest volume and the smallest footprint, allowing it to hold the most tap water. The inner wall of the circular water tank 1 has a relatively large unevenness, reducing dead corners for cleaning and facilitating workers to enter the circular water tank 1 through the manhole assembly 3 for cleaning. Furthermore, the shorter wavelength and more ribs of the lower rib plate 5 significantly improve the pressure-bearing capacity of the circular water tank 1, while the longer wavelength and fewer ribs of the upper rib plate 4 reduce the amount of welding and costs, thus improving the pressure-bearing capacity of the water tank while reducing corresponding manufacturing costs. When workers perform internal cleaning of the circular water tank 1, they press the circular push rod 19 while pulling up the handle 9. At this time, the horizontal end of the L-shaped slider 14 does not align with the cross-shaped latch. Block 12 restricts the sealing cover 8 from the opening 7, enabling quick and easy opening of the opening 7. After inspection and cleaning, the worker attaches the sealing cover 8 to the locking block 12. At this time, the concave frame 10 presses and pushes one side of the cross-shaped locking block 12 and restricts it at 90 degrees, entering the space formed by the cross-shaped locking block 12 and the inner wall of the fixing groove 11. During this process, the other side of the cross-shaped locking block 12 pushes the L-shaped slider 14 upward toward the vertical surface of the round rod 13 and then falls back, so that the horizontal end of the L-shaped slider 14 restricts one side of the cross-shaped locking block 12, thereby achieving the effect of fixing the concave frame 10 in the fixing groove 11. This helps to reduce the safety hazard of workers forgetting to lock the sealing cover 8 after cleaning.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
