This cooling is typically provided by refrigeration equipment, which operates for extended periods. Furthermore, the demand for cooling is generally high during the day and low at night, necessitating frequent start-ups and shutdowns of the refrigeration equipment. This significantly increases the risk and frequency of equipment failure.

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] This application discloses a construction method for a basement cold water storage tank.

[0030] Reference Figure 1 , Figure 2 as well as Figure 3 The construction method for a basement cold water storage tank includes the following steps: S1, installation and connection of water distribution pipes in the storage tank; S2, suspension of the water distributor 1 to the top floor slab inside the storage tank via screw rods, and support by supporting angle steel; S3, laying drainage boards on the original concrete floor of the storage tank, and laying a reinforced concrete layer on the drainage boards; S4, cleaning the reinforced concrete layer inside the storage tank, applying waterproof coating, and building an adhesive layer; S5, building a heat insulation layer on the top of the storage tank.

[0031] It should be noted that this construction method is carried out in a pre-set water tank, and the purpose of this construction method is to enable the water tank to store cold water for providing cooling capacity.

[0032] A floor slab is installed on the top of the water tank. The water distributor 1 is suspended from the floor slab by a screw rod, and the water supply port of the water distributor 1 is connected to the water outlet port of the water distribution pipe. S3 is the construction measure of the water tank drainage layer. The drainage layer is mainly composed of the original concrete layer of the water tank, the drainage board and the reinforced concrete layer. The drainage board is laid on the original concrete layer of the water tank. The reinforced concrete layer is poured on the laid drainage board to prevent the back pressure of the surface water. The waterproof and heat insulation measures are built on the basis of the reinforced concrete layer.

[0033] S4 and S5 involve the construction of a waterproof and thermal insulation layer, which is mainly divided into a concrete layer, a primer layer, a high-density thermal insulation layer, an adhesive layer, and a waterproof layer (in this embodiment, the high-density thermal insulation layer can be made of rigid polyurethane foam, the adhesive layer uses a polyurea-specific primer, and the waterproof layer can be made of polyurea).

[0034] The reinforced concrete layer at the bottom of the pool is ground smooth (in this embodiment, a polishing machine in the prior art is used to grind the concrete layer smooth), and a primer layer, a high-density heat insulation layer, an adhesive, and a waterproof layer are sprayed sequentially on the surface of the concrete layer.

[0035] The primer layer acts as an adhesion promoter, allowing the high-density insulation layer to fully adhere to the smoothed concrete surface. After the high-density insulation layer hardens on the concrete surface, it forms a waterproof layer. This waterproof layer on the primer surface prevents moisture or water from penetrating through the concrete surface and contacting the high-density insulation layer, thus preventing a decrease in the insulation performance of the chilled water storage tank system, whether installed outdoors or underground. The installation of drainage boards reduces the deformation or damage to the waterproof insulation layer caused by accumulated surface water pressing against it.

[0036] In another embodiment of this application, in step S2, a support base is fixedly installed at the bottom of the pool by bolts, the water distributor 1 is mounted on the support base and fixed by bolts, and the water supply port of the water distributor 1 is connected to the water outlet port of the water distribution pipe. It should be noted that the water distributor 1 in this embodiment can only be installed after the waterproof and heat insulation measures and drainage measures are completed.

[0037] To achieve the cooling effect on the cold water, a refrigeration unit needs to be installed. The refrigeration unit can be a refrigeration pump, with the cooling end of the refrigeration pump extending into the water tank to cool the water (it should be noted that waterproofing measures must be taken for the refrigeration pump before operation).

[0038] In order to accurately grasp the cooling effect data of the cold storage water tank, a temperature measuring unit (in this embodiment, the temperature measuring unit can be a thermometer commonly used for underwater temperature measurement in industry) needs to be set up at every end along the longitudinal direction of the water tank. An integrated substation is also established, and several temperature measuring units are connected to the integrated substation to transmit the water temperature of the water tank to the integrated substation so that the staff can control the water temperature data.

[0039] The spacing between the temperature measuring units can be set by the staff. In this embodiment, the spacing between the temperature measuring units is 25cm. The temperature measuring units can be installed on the inner wall of the water tank, or they can be fixed on the support column in the water tank and the temperature measuring units are fixed on the support column for measurement (the support column must be kept vertical to ensure that the spacing between the temperature measuring units is the spacing set by the staff).

[0040] Through the above-mentioned setup, a drainage layer is laid at the bottom of the pool to prevent water from remaining at the bottom for a long time, reducing the risk of leakage and alleviating the water pressure on the bottom of the pool, thereby improving the stability of the pool structure. In order to reduce the power consumption caused by the demand for cooling during the day, the water in the pool is cooled at night by a refrigeration unit. The waterproof and heat-insulating layer built on the drainage layer plays a role in keeping the water temperature in the storage pool, making full use of nighttime power resources and reducing power consumption during peak hours.

[0041] Reference Figure 4 and Figure 5In one embodiment of this application, the water distributor 1 includes a water storage tank 11, multiple water guiding mechanisms 2, multiple driving mechanisms 3, and a buffer mechanism 4. The water storage tank 11 is suspended from the lower end of the lead screw, and the interior of the water storage tank 11 is hollow with a water supply port at the lower end. The water outlet port of the water distribution pipe is fixedly connected to the water supply port of the water storage tank 11.

[0042] Several water guiding mechanisms 2 are evenly arranged around the water storage tank 11 and are used to spray water from the water storage tank 11 into the water pool. A driving mechanism 3 is located at the end of the water guiding mechanism 2 away from the water storage tank 11 and is used to drive the water guiding mechanism 2 to output water evenly. The water guiding mechanism 2 includes a water guiding column 21 and a spiral rod 22. The water guiding column 21 is hollow inside and has openings at both ends. The water guiding column 21 is fixedly connected to the side wall of the water storage tank 11 and communicates with the inner cavity of the water storage tank 11.

[0043] The spiral rod 22 is located inside the water guide column 21 and one end is connected to the drive mechanism 3. The side wall of the water guide column 21 is provided with a spray nozzle 23. When the water distribution pipe delivers water to the water storage tank 11, due to the large water pressure, the water flows through the inner cavity of the water guide column 21 and sprays outward through the spray nozzle 23. Since the water flow delivered by the water distribution pipe is prone to contain sand and other particulate impurities, it is easy to cause the spray nozzle 23 to be blocked, resulting in uneven water distribution effect of the water distributor 1 and forming dead corners at the bottom of the pool. Moreover, due to the blockage of the spray nozzle 23 inside the water guide column 21, the water pressure will increase, which can easily damage the water guide column 21. The spiral blades of the spiral rod 22 rotate under the drive mechanism by the water flow injected into the water guide column 21, thereby reducing the occurrence of impurities blocking the spray nozzle 23. The buffer mechanism 4 is located inside the water storage tank 11 and is used to buffer the water flow input into the water distributor 1 in the water distribution pipe.

[0044] With the above settings, water is supplied to the water distributor 1 through the water distribution pipe. The water flow is buffered by the buffer mechanism 4 and flows into each water guide column 21. It is then sprayed into the water pool through the spray nozzle 23. The spiral rod 22 rotates under the drive of the drive mechanism 3 and drives the water flow in the water guide column 21 to flow around it, reducing the phenomenon of impurities clogging the spray nozzle 23, improving the uniformity of water flow spraying through the water distributor 1, reducing the occurrence of dead corners, and reducing the impact on the inner wall of the water guide column 21.

[0045] Reference Figure 5 The buffer mechanism 4 includes several buffer springs 41 and a buffer plate 42. The upper ends of the buffer springs 41 are fixedly connected to the upper surface of the inner cavity of the water storage tank 11, and the buffer springs 41 are arranged circumferentially along the axis of the water storage tank 11. The lower ends of the buffer springs 41 are fixedly connected to the buffer plate 42. Through the extension and retraction of the buffer springs 41, the buffer plate 42 can slide longitudinally in the inner cavity of the water storage tank 11.

[0046] Because water needs considerable pressure to be sprayed through nozzle 23, and when water is directly forced into the inner cavity of water storage tank 11 from the outlet port at the bottom of the water distribution pipe, it will impact the upper wall of the inner cavity of water storage tank 11. After long-term use, the upper part of water storage tank 11 is prone to damage. When water flows into the inner cavity of water storage tank 11, the buffer plate 42 slides upward by the elastic force of the buffer spring 41, so that it can buffer the water pressure.

[0047] To facilitate the flow of water after being buffered by the buffer plate 42 into each water guide column 21, the lower surface of the buffer plate 42 is provided with an arc-shaped protrusion. When the buffer plate 42 is buffering, the water flowing towards the center of the buffer plate 42 flows towards the edge of the buffer plate 42 under the action of the arc-shaped protrusion of the buffer plate 42, so that the buffered water can flow into the water guide column 21 better and be sprayed from the spray nozzle 23.

[0048] Reference Figure 5 and Figure 6 The drive mechanism 3 includes a connecting column 31, a drive motor 32, a rotating assembly 33, and a threaded rod 34. The connecting column 31 is bolted to the end of the water guide column 21 facing away from the water storage tank 11. The connecting column 31 is hollow and has an opening at the end facing the water guide column 21. The rotating assembly 33 is disposed in the cavity of the connecting column 31. One end of the threaded rod 22 rotates through the opening of the connecting column 31 and is connected to the rotating assembly 33. A fixing frame is bolted to the end of the connecting column 31 facing away from the water guide column 21. The drive motor 32 is mounted on the fixing frame and fixed with bolts. A waterproof plate is provided around the drive motor 32 to prevent damage to the drive motor 32 due to water contact. The output shaft of the drive motor 32 is coaxially fixedly connected to the threaded rod 34 through a coupling. The end of the threaded rod 34 facing away from the drive motor 32 extends into the connecting column 31 and is connected to the rotating assembly 33. The connecting column 31 has an opening at the end opposite to the water guide column 21 for the rotating assembly 33 to be inserted into the cavity of the connecting column 31, and a removable protective cover is fixedly connected to the opening by bolts. (In another embodiment of this application, the water distributor located at the bottom of the pool needs to seal the drive motor 32 to prevent damage to the drive motor 32 after it comes into contact with water.)

[0049] With the above configuration, the output shaft driven by the drive motor 32 drives the rotating component 33 to rotate, causing the spiral rod 22 to rotate in the inner cavity of the water guide column 21. This allows water to flow into the water guide column 21 and wash the blades of the spiral rod 22, thus driving the spiral rod 22 to rotate. This causes the water flow in the inner cavity of the water guide column 21 to circulate around the spiral rod 22, reducing the occurrence of impurities clogging the spray nozzle 23.

[0050] Reference Figure 6In another embodiment of this application, the drive motor 32 and the screw rod 22 are connected by a rotating assembly 33.

[0051] The rotating assembly 33 includes: a linkage block 331, a limiting block 332, a limiting rod 333, a limiting piece 334, and a fixing ring 335. The linkage block 331 is disposed in the inner cavity of the connecting column 31 and threadedly sleeved with the threaded rod 34. The interior of the linkage block 331 is hollow and has an opening facing away from the threaded rod 34. The limiting rod 333 is fixedly connected to the bottom of the connecting column 31 by bolts, and one end of the limiting rod 333 extends into the inner cavity of the linkage block 331. The linkage block 331 has an arc-shaped groove 336 through it, and the limiting rod 333 passes through the arc-shaped groove 336. Through the opening of the arc-shaped groove 336, the linkage block 331 is limited when it rotates with the output shaft of the drive motor 32.

[0052] The limiting block 332 is located in the inner cavity of the linkage block 331 and is fixedly connected to the limiting rod 333 by bolts. The end of the threaded rod 34 facing away from the drive motor 32 is rotatably connected to the limiting block 332. The end of the limiting block 332 facing away from the drive motor 32 is open to prevent the spiral rod 22 from moving and colliding with the limiting block 332 when it is subjected to a large impact from the water flow.

[0053] Reference Figure 6 and Figure 7 The limiting piece 334 is fixedly sleeved on the end of the spiral rod 22 that extends into the inner cavity of the limiting block 332, and an annular protrusion is welded on the side of the limiting piece 334 away from the limiting block 332. The fixing ring 335 is fixedly connected to the opening of the linkage block 331 by bolts. An annular groove is opened on the side of the fixing ring 335 facing the limiting piece 334, and multiple linkage components 35 are arranged in the annular groove. The annular protrusion is clamped in the annular groove by the linkage components 35.

[0054] In the initial state, when the annular protrusion is located in the annular groove, when the output shaft of the drive motor 32 rotates, the linkage block 331 drives the spiral rod 22 to rotate through the linkage assembly 35. When the water flows from the water storage tank 11 into the guide column 21, the spiral rod 22 rotates under the impact of the water flow. When the linkage block 331 rotates with the output shaft of the drive motor 32 until the side wall of the limit rod 333 abuts against the end of the arc groove 336, the linkage block 331 moves along the threaded rod 34 toward the guide column 21 under the restriction of the arc groove 336, so that the linkage block 331 separates from the spiral rod 22, so as to avoid the phenomenon that the output shaft of the drive motor 32 is damaged due to the excessive impact of the water flow on the spiral blades of the spiral rod 22 causing the spiral rod 22 to rotate too fast.

[0055] Reference Figure 7The linkage component 35 includes a telescopic spring 351 and a locking protrusion 352. A groove is provided on the inner wall of the annular groove. The telescopic spring 351 is embedded in the groove, and one end of the telescopic spring 351 is welded to the bottom of the groove. One end of the locking protrusion 352 extends into the groove and is fixedly connected to the telescopic spring 351. The end of the locking protrusion 352 extending out of the groove abuts against the annular protrusion. Under the elastic force of the telescopic spring 351, the annular protrusion is pressed against the inner wall of the annular groove, so that the linkage block 331 can drive the annular protrusion to rotate under the drive of the drive motor 32, that is, drive the screw rod 22 to rotate.

[0056] In this embodiment, the drive motor 32 can be a servo motor, which can reverse the motor to make the annular protrusion press against the annular groove again, so that when water is injected into the water column 21 again, the drive motor 32 can drive the linkage block 331 to rotate the screw rod 22.

[0057] In order to facilitate the re-engagement of the annular protrusion into the annular groove, the edge of the locking protrusion 352 is set in an arc shape.

[0058] In another embodiment of this application, in order to facilitate the rotation of the screw rod 22 under the impact of water flow, a groove is provided on the inner wall of the limiting block 332, and a bushing 36 is fixedly embedded in the groove. A rolling element 37 is embedded in the center of the bushing 36, and the rolling element 37 and the bushing 36 are in a rolling connection. When the water flow pushes the screw rod 22 toward the connecting column 31, the end of the screw rod 22 abuts against the rolling element 37 to facilitate the rotation of the screw rod 22.

[0059] To prevent damage to the rolling element 37 caused by the impact of water flow on the screw rod 22, a limiting groove 24 is formed along its circumference on the inner wall of the water guide column 21, and a limiting disc 25 is fixedly sleeved on the side wall of the screw rod 22. The limiting disc 25 is slidably connected in the limiting groove 24. Due to the limiting effect of the limiting groove 24, the end of the screw rod 22 cannot continue to move towards the drive motor 32 after it abuts against the rolling element 37. At the same time, since the limiting disc 25 abuts against the inner wall of the limiting groove 24, the shaking of the screw rod 22 caused by the impact of water flow on the helical blades of the screw rod 22 is reduced. (It should be noted that in order to avoid the water flow blockage in the water guide column 21 due to the presence of the limiting disc 25, the limiting disc 25 should be set at the end of the water guide column 21 away from the water storage tank 11.)

[0060] The implementation principle of this embodiment is as follows: a drainage layer and a waterproof and heat-insulating layer are laid in the water tank. Water is injected into the water tank through the water distributor 1, and the water in the water tank is cooled by the cooling unit. Due to the presence of the waterproof and heat-insulating layer, the water temperature can be kept at a low temperature. The water injection and cooling operations in the water tank are carried out at night to reduce the waste of electricity at night and reduce the use of electricity during peak hours.

[0061] Because impurities in the water clog the spray nozzles 23 of the water distributor 1, preventing the water distributor 1 from spraying water evenly, which may affect the cooling effect on the water in the pool, a spiral rod 22 is installed inside the water guide column 21. When water flows into the water guide column 21, the spiral blades of the spiral rod 22 are driven to rotate under the impact of the water flow, causing the water in the water guide column 21 to flow around the spiral rod 22 in a circumferential direction, reducing the occurrence of impurity blockage. The drive motor 32 at the end of the water guide column 21 rotates, driving the linkage block 331 to rotate. Because the locking protrusion 352 is pressed against the annular protrusion under the elastic force of the telescopic spring 351, the spiral rod 22 rotates with the linkage block 331, so that the water flow can reach the water guide column 21 and drive the spiral rod 22 to rotate.

[0062] When the linkage block 331 rotates to the point where the end of the arc-shaped groove 336 abuts against the limiting rod 333, the linkage block 331 moves toward the spiral rod 22 under the limitation of the limiting rod 333. At the same time, the annular protrusion moves out of the annular groove to avoid the spiral rod 22 from driving the output shaft of the drive motor 32 to rotate for a long time under the impact of the water flow, which would affect the rotor and other structures inside the drive motor 32. After the water distributor 1 has finished distributing water, the output shaft of the drive motor 32 can be reversed to make the linkage block 331, which is threaded to the threaded rod 34, move away from the spiral rod 22 under the limitation of the limiting rod 333. The annular protrusion re-engages in the annular groove and abuts against the locking protrusion 352, so that the water distributor 1 can distribute water again.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
