Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel water tanks, in particular to an underground stainless steel water tank with good pressure resistance. Background Art

[0002] In-ground stainless steel water tanks are a new type of water supply equipment that has become increasingly popular in recent years with advancements in construction technology and rising demands for environmental protection and energy conservation. Compared to traditional above-ground tanks, these tanks offer several advantages, including increased efficiency, energy savings, aesthetics, and environmental friendliness. They are particularly suitable for large complexes, high-rise buildings, and areas with high demands for environmental landscapes. In-ground stainless steel water tanks are insulated, especially in cooler climates. This insulation minimizes heat loss and maintains a stable water temperature within the tank.

[0003] Generally, a protective outer shell is set outside the water tank, and thermal insulation filler is set between the water tank and the protective outer shell. However, in order to ensure the stability between the water tank and the protective outer shell, the water tank and the outer protective shell are connected by metal connectors. Metal connectors have a high thermal conductivity coefficient. They can form thermal bridges, making it easier for heat to be transferred through these connection points, thereby reducing the overall thermal insulation effect of the insulation layer.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1-2 As shown, the utility model proposes an underground stainless steel water tank with good pressure resistance, including a water tank 1 and a water inlet 101 provided on the water tank 1, through which cold water can be transported to the inside of the water tank 1. It also includes a protective shell 204 fixedly installed on the water tank 1, a thermal insulation layer is provided between the protective shell 204 and the water tank 1, and the protective shell 204 is fixedly connected to the water tank 1 through two sets of staggered connectors, and a partition 201 is fixedly installed between the two sets of connectors. The two sets of staggered connectors make the protective shell 204 and the water tank 1 indirectly connected, and the two staggered connectors disperse the heat transfer path, thereby reducing the heat flux density at each connection point and reducing the thermal bridge effect. The partition 201 and the staggered structure increase the length of the heat flow path, thereby increasing the thermal resistance of the system and helping to reduce heat loss.

[0029] Furthermore, one set of connectors includes a plurality of first insulation nails 2 fixedly mounted on the water tank 1, and a partition 201 fixedly mounted on the plurality of first insulation nails 2; another set of connectors includes a plurality of second insulation nails 203 fixedly mounted on the partition 201, and a protective shell 204 fixedly mounted on the plurality of second insulation nails 203; the first insulation nails 2 and the second insulation nails 203 are not in a coaxial position. The water tank 1 and the protective shell are fixedly connected by the first insulation nails 2 and the second insulation nails 203, and the first insulation nails 2 and the second insulation nails 203 are fixedly connected via the partition, so that the water tank 1 and the protective shell 204 can maintain a stable connection effect, and can effectively reduce the thermal bridge effect, which helps to reduce heat loss.

[0030] The insulation layer includes a first insulation filler 202 fixedly mounted between the partition 201 and the water tank 1, a second insulation filler 205 fixedly mounted between the partition 201 and the protective shell 204, and a third insulation filler 206 fixedly mounted on both the upper and lower sides of the water tank 1. The first insulation filler 202, the second insulation filler 205, and the third insulation filler 206 prevent the loss of cold energy within the water tank 1, thereby maintaining a good insulation effect within the water tank 1.

[0031] like Figure 1-2As shown, the drainage pipe is fixedly installed at the bottom of the water tank 1. The drainage pipe includes a drainage pipe 3 fixedly installed at the bottom of the water tank 1. A thermal insulation ring 301 is fixedly installed on the drainage pipe 3. A connecting pipe 302 is fixedly installed on the thermal insulation ring 301. The connecting pipe 302 passes through the bottom of the protective shell 204 and extends to the outside of the protective shell 204. When draining, the water in the water tank 1 will enter the thermal insulation ring 301 through the drainage pipe 3, and then enter the connecting pipe 302 through the thermal insulation ring 301. The thermal insulation ring separates the metal drainage pipe 3 and the connecting pipe 302, which can effectively prevent the thermal bridge effect when the drainage pipe 3 and the connecting pipe 302 are connected together, which is conducive to improving the thermal insulation effect of the water tank 1. However, after drainage, the drain pipe 3 and the connecting pipe 302 will be filled with liquid. When drainage stops, the water in the drain pipe 3 and the connecting pipe 302 will stay inside the drain pipe 3 and the connecting pipe 302. The water at this time will come into contact with the water in the water tank 1. The water inside the drain pipe 3 and the connecting pipe 302 is located outside the water tank 1 and has no insulation measures. Therefore, after the water in the drain pipe 3 and the connecting pipe 302 heats up, it will exchange heat with the water in the water tank 1, which is not conducive to insulating the water tank 1.

[0032] like Figure 2-6 As shown, the drain pipe is equipped with a circuit-breaking insulation structure, which divides the water in the drain pipe into two groups and maintains a certain distance between the two groups of water. By isolating the water in the drain pipe 3 and the connecting pipe 302 from the water in the water tank 1, it is possible to effectively prevent the cold inside the water tank 1 from being dissipated through the drain pipe 3 and the connecting pipe 302, thereby effectively improving the insulation effect of the water tank 1. The circuit-breaking insulation structure includes a motor base 4 fixedly mounted in the protective housing 204, a first motor 401 fixedly mounted on the motor base 4, a valve core 402 rotatably mounted in the drain pipe 3, and the output shaft of the first motor 401 is fixedly connected to the valve core 402. By driving the valve core 402 to rotate by the first motor 401, the valve core 402 can block the drain pipe 3, thereby isolating the water in the water tank 1 from the water in the drain pipe 3.

[0033] Furthermore, a second motor 403 is fixedly mounted on the motor base 4, and a transmission rod 404 is fixedly mounted on the output shaft of the second motor 403. The transmission rod 404 passes through one side of the insulation ring 301 and extends to the middle of the insulation ring 301. An eccentric wheel 405 is fixedly mounted on one end of the transmission rod 404 located inside the insulation ring 301. A connecting rod 406 is rotatably mounted on the eccentric wheel 405. A guide sleeve 407 is fixedly mounted inside the connecting tube 302. A lifting rod 408 is slidably mounted inside the guide sleeve 407. One end of the lifting rod 408 is rotatably connected to the connecting rod 406, and the other end of the lifting rod 408 is fixedly mounted on a plugging head 409. The second motor 403 can drive the eccentric wheel 405 to rotate, and the rotating eccentric wheel 405 will drive the connecting rod 406 to rotate. The rotating connecting rod 406 will drive the lifting rod 408 to move along the axial direction of the guide sleeve 407, thereby causing the plugging head 409 to move up and down.

[0034] Furthermore, a support block 410 is slidably installed in the connecting tube 302, and a first flow hole 411 is provided on the support block 410. A base plate 412 is fixedly installed in the connecting tube 302, and a second flow hole 413 is provided on the base plate 412. A plurality of telescopic rods 414 are fixedly installed on the base plate 412, and the other end of the telescopic rod 414 is fixedly connected to the support block 410, and a first spring 415 is fixedly installed in the telescopic rod 414. When the blocking head 409 moves downward, the blocking head 409 will contact the support block 410 and the blocking head 409 will block the first flow hole 411, which can cut off the water in the connecting pipe 302. At this time, the water in the drain pipe 3 will accumulate on the blocking head 409 and the support block 410 under the action of gravity. As the second motor 403 continues to rotate, the blocking head 409 will continue to be driven downward through the connecting rod 406. At this time, the blocking head 409 will drive the support block 410 to move downward, thereby causing the water accumulated on the blocking head 409 and the support block 410 to move downward, so that the water in the drain pipe 3 and the water inside the water tank 1 are spaced a certain distance apart, thereby effectively preventing the water in the water tank 1 from exchanging heat with the connecting pipe 302 and the water inside the drain pipe 3, thereby effectively improving the thermal insulation performance.

[0035] The support block 410 is provided with a pressure groove 5, the plugging head 409 is fixedly mounted with a sealing pressure ring 501, and the support block 410 is fixedly mounted with a sealing ring 502. The combination of the sealing pressure ring 501 and the pressure groove 5 can effectively improve the sealing between the plugging head 409 and the support block 410, and the provision of the sealing ring 502 can effectively improve the sealing between the support block 410 and the connecting pipe 302.

[0036] The connecting pipe 302 is fixedly mounted with a water tank 6, within which a pressure plate 601 is slidably mounted. A second spring 602 is fixedly mounted on the pressure plate 601. The other end of the second spring 602 is fixedly connected to the inner wall of the water tank 6, thereby connecting the water tank 6 to the connecting pipe 302. When the support block 410 moves downward, it squeezes the water inside the connecting pipe 302, allowing the water inside the connecting pipe 302 to flow into the water tank 6, thus preventing damage to the connecting pipe 302 caused by increased water pressure.

[0037] The operating principle of this embodiment is that two sets of staggered connectors provide an indirect connection between the protective housing 204 and the water tank 1. These staggered connectors disperse the heat transfer path, reducing the heat flux density at each connection point and minimizing the thermal bridge effect. The baffles 201 and staggered structure increase the length of the heat flow path, thereby increasing the thermal resistance of the system and helping to reduce heat loss.

[0038] By isolating the water in the drain pipe 3 and the connecting pipe 302 from the water in the water tank 1, the cold energy inside the water tank 1 can be effectively prevented from being dissipated through the drain pipe 3 and the connecting pipe 302, thereby effectively improving the thermal insulation effect of the water tank 1.

[0039] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
