DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The embodiment of the present 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 of the basement cold water tank includes the following steps: S1, installing and connecting the water distribution pipes in the water tank; S2, suspending the water distributor 1 on the top floor of the water tank through a screw, and supporting it through a supporting angle steel; S3, laying a drainage board on the original concrete floor of the water tank, and laying a reinforced concrete layer on the drainage board; S4, cleaning the reinforced concrete layer in the water tank, applying waterproof coating, and building an adhesive layer; S5, building a thermal insulation layer on the top of the water tank.

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

[0032] A floor is arranged on the top of the pool, and a water distributor 1 is suspended on the floor by a screw, and a water supply port of the water distributor 1 is connected with a water outlet port of a water distribution pipe. S3 is a construction measure for a drainage layer of the pool, and the drainage layer is mainly composed of an original concrete layer of the pool, a drainage board and a reinforced concrete layer, wherein the drainage board is laid on the original concrete layer of the pool, and a reinforced concrete layer is poured on the laid drainage board to prevent back squeezing of surface water, and waterproof and heat-insulating measures are constructed 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 (wherein the high-density thermal insulation layer of this embodiment can adopt hard polyurethane foam, the adhesive layer adopts a polyurea special primer, and the waterproof layer can adopt polyurea).

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

[0035] Among them, the primer layer acts as an adhesive, allowing the high-density thermal insulation layer to fully adhere to the surface of the smoothed concrete layer. The high-density thermal insulation layer forms a waterproof layer after solidification and hardening on the surface of the concrete layer. The waterproof layer formed on the surface of the primer layer can prevent moisture or water from penetrating through the surface of the concrete layer and contacting the high-density thermal insulation layer that has a thermal insulation function. Even if the cold water storage tank system is installed outdoors or underground, it can prevent the thermal insulation performance of the cold water storage tank system from being reduced. The laying of the drainage board reduces the deformation or damage to the waterproof and thermal insulation layer caused by the accumulation of surface water and the squeezing of the waterproof and thermal insulation layer.

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

[0037] In order to achieve the cooling effect on cold water, a refrigeration unit needs to be installed. The refrigeration unit can be a refrigeration pump. The refrigeration end of the refrigeration pump extends into the water pool to achieve the cooling of the water (it should be noted that the refrigeration pump needs to be waterproofed before operation).

[0038] In order to accurately grasp the cooling effect data of the cold water storage tank, a temperature measuring unit is required to be set at every end distance along the longitudinal direction of the water storage tank (the temperature measuring unit in this embodiment can be a thermometer commonly used for underwater temperature measurement in industry), and an integrated substation is established. Several temperature measuring units are connected to the integrated substation, and the water temperature of the water storage tank is transmitted to the integrated substation to facilitate the staff to control the water temperature data.

[0039] Among them, the spacing between the temperature measuring units can be set by the staff. In this embodiment, the spacing between the temperature measuring units is 25 cm, and the temperature measuring units can be installed on the inner wall of the pool, or by fixing support columns in the pool and fixing the temperature measuring units on the support columns for measurement (the support columns need to be kept vertical to ensure that the spacing between the temperature measuring units is the spacing set by the staff).

[0040] Through the above arrangement, a drainage layer is laid at the bottom of the pool to prevent water from being retained at the bottom of the pool for a long time, reduce the risk of leakage, reduce the water pressure at the bottom of the pool, and improve 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 by a refrigeration unit at night, and the waterproof and thermal insulation layer built on the basis of the drainage layer plays a role in insulating the water temperature in the reservoir, making full use of power resources at night and reducing power usage during peak hours.

[0041] Reference Figure 4 and Figure 5In one embodiment of the present 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 at the lower end of the screw, and the interior of the water storage tank 11 is hollow and a water supply port is opened 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] A plurality of water guiding mechanisms 2 are evenly arranged along the circumference of the water storage tank 11, and are used to spray the water in the water storage tank 11 into the water pool. The driving mechanism 3 is arranged at one 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 discharge water evenly. The water guiding mechanism 2 includes a water guiding column 21 and a spiral rod 22. The interior of the water guiding column 21 is hollow 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 is communicated with the inner cavity of the water storage tank 11.

[0043] The spiral rod 22 is arranged in the inner cavity of the water guide column 21 and one end is connected to the driving mechanism 3. A water spray port 23 is opened on the side wall of the water guide column 21. When the water distribution pipe transports 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 is sprayed to the surroundings through the water spray port 23. Since gravel and other granular impurities are easily present in the water flow transported by the water distribution pipe, the water spray port 23 is easily blocked, making the water distribution effect of the water distributor 1 uneven, forming a dead angle at the bottom of the pool, and in the water guide column 21, due to the blockage of the water spray port 23, the water pressure will increase, which is easy to damage the water guide column 21. Driven by the driving mechanism, the spiral blades of the spiral rod 22 rotate through the water flow injected into the water guide column 21, thereby reducing the occurrence of impurities blocking the water spray port 23. The buffer mechanism 4 is arranged in the inner cavity of 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] Through the above arrangement, water is transported 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, and is sprayed toward the pool through the water nozzle 23. The spiral rod 22 rotates under the drive of the driving mechanism 3, and drives the water flow in the water guide column 21 to flow around it, reducing the phenomenon of impurities blocking the water nozzle 23, improving the uniformity of water spraying through the water distributor 1, reducing the occurrence of dead corners, and the impact on the inner wall of the water guide column 21.

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

[0046] Since the water flow needs a relatively large pressure to be ejected through the water spout 23, and the water flow directly presses into the inner cavity of the water storage tank 11 from the water delivery port at the bottom of the water storage tank 11 through the water outlet port of the water distribution pipe, it will impact the upper wall of the inner cavity of the water storage tank 11. After long-term use, the upper end of the water storage tank 11 is easily damaged. When the water flow fills the inner cavity of the water storage tank 11, the buffer plate 42 slides upward through the elastic force of the buffer spring 41, so that it plays the role of buffering the water pressure.

[0047] In order to facilitate the water flow buffered by the buffer plate 42 to flow into each water guide column 21, the lower surface of the buffer plate 42 is arranged in an arc-shaped convex configuration. When the buffer plate 42 is buffering, the water flow flowing toward the center of the buffer plate 42 flows toward the edge of the buffer plate 42 under the action of the arc-shaped convex surface of the buffer plate 42, so that the water flow after buffering can better flow into the water guide column 21 and be sprayed from the water nozzle 23.

[0048] Reference Figure 5 and Figure 6 The driving mechanism 3 includes a connecting column 31, a driving motor 32, a rotating assembly 33 and a threaded rod 34. The connecting column 31 is fixedly connected to the end of the water guide column 21 away from the water storage tank 11 by bolts, and the interior of the connecting column 31 is hollow and has a through hole toward the end of the water guide column 21. The rotating assembly 33 is arranged in the cavity of the connecting column 31. One end of the spiral rod 22 is rotated and penetrated through the through hole of the connecting column 31 and is connected to the rotating assembly 33. The end of the connecting column 31 away from the water guide column 21 is fixedly connected to a fixing frame by bolts. The driving motor 32 is mounted on the fixing frame and fixed by bolts. A waterproof plate is arranged around the fixing frame around the driving motor 32, and is used to prevent the driving motor 32 from being damaged by water. The output shaft of the driving motor 32 is coaxially fixedly connected to the threaded rod 34 through a coupling. The end of the threaded rod 34 away from the driving motor 32 extends into the connecting column 31 and is connected to the rotating assembly 33. An opening is provided at one end of the connecting column 31 away from the water-guiding column 21 for the rotating assembly 33 to be installed in the cavity of the connecting column 31, and a detachable protective cover is fixedly connected to the opening by bolts. (In another embodiment of the present application, the water distributor arranged at the bottom of the pool needs to seal the drive motor 32 to avoid damage to the drive motor 32 after contact with water).

[0049] Through the above-mentioned arrangement, the output shaft driven by the driving motor 32 drives the rotating assembly 33 to rotate, so that the spiral rod 22 rotates in the inner cavity of the water guide column 21, so that the water flows into the water guide column 21 to flush the blades of the spiral rod 22, thereby driving the spiral rod 22 to rotate, so that the water flow in the inner cavity of the water guide column 21 circulates around the spiral rod 22, thereby reducing the occurrence of impurities blocking the water spray port 23.

[0050] Reference Figure 6In another embodiment of the present application, the driving motor 32 is connected to the screw rod 22 via a rotating assembly 33 .

[0051] The rotating assembly 33 includes: a linkage block 331, a limit block 332, a limit rod 333, a limit plate 334 and a fixing ring 335. The linkage block 331 is arranged in the inner cavity of the connecting column 31 and is threadedly sleeved with the threaded rod 34. The interior of the linkage block 331 is hollow and is opened toward the side away from the threaded rod 34. The limit rod 333 is fixedly connected to the bottom of the connecting column 31 by bolts, and one end of the limit rod 333 extends into the inner cavity of the linkage block 331. The linkage block 331 is penetrated by an arc groove 336, and the limit rod 333 is penetrated by the arc groove 336. Through the opening of the arc groove 336, the linkage block 331 is limited when the output shaft of the drive motor 32 rotates.

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

[0053] Reference Figure 6 and Figure 7 The limiting plate 334 is fixedly sleeved on the end of the spiral rod 22 extending into the inner cavity of the limiting block 332, and an annular protrusion is welded on the side of the limiting plate 334 away from the limiting block 332. The fixing ring 335 is fixedly connected to the opening of the linkage block 331 by bolts. The fixing ring 335 is provided with an annular groove on the side facing the limiting plate 334, and a plurality of linkage components 35 are arranged in the annular groove, and the annular protrusion is clamped in the annular groove through the linkage component 35.

[0054] In the initial state, when the annular protrusion is located in the annular groove, when the output shaft of the driving motor 32 rotates, the linkage block 331 drives the screw rod 22 to rotate through the linkage assembly 35, and when the water flows from the water storage tank 11 into the water guide column 21, the screw rod 22 can rotate under the impact of the water flow. When the linkage block 331 rotates with the output shaft of the driving motor 32 until the side wall of the limiting rod 333 abuts against the end of the arc groove 336, under the restriction of the arc groove 336, the linkage block 331 moves along the threaded rod 34 toward the water guide column 21, and the linkage block 331 is separated from the screw rod 22 to avoid the output shaft of the driving motor 32 being damaged due to excessive impact of the water flow on the spiral blades of the screw rod 22, which causes the speed of the screw rod 22 to be too fast.

[0055] Reference Figure 7The linkage assembly 35 includes a telescopic spring 351 and a locking protrusion 352. A groove is opened 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, and 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 driving motor 32, that is, drive the spiral rod 22 to rotate.

[0056] The driving motor 32 in the embodiment of the present application 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 guide column 21 again, the driving motor 32 can drive the linkage block 331 to drive the spiral rod 22 to rotate.

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

[0058] In another embodiment of the present application, in order to facilitate the rotation of the screw rod 22 under the impact of the water flow, an embedding groove is opened on the inner wall of the limit block 332, and a shaft sleeve 36 is fixedly embedded in the embedding groove. A rolling body 37 is embedded in the center of the shaft sleeve 36, and the rolling body 37 and the shaft sleeve 36 are rollingly connected. 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 body 37 to facilitate the rotation of the screw rod 22.

[0059] In order to prevent the spiral rod 22 from damaging the rolling body 37 under the impact of the water flow, a limiting groove 24 is provided on the inner wall of the water guide column 21 along its circumferential direction, and a limiting plate 25 is fixedly sleeved on the side wall of the spiral rod 22. The limiting plate 25 is slidably connected in the limiting groove 24. Due to the limiting effect of the limiting groove 24, the end of the spiral rod 22 cannot continue to move toward the drive motor 32 after abutting against the rolling body 37. At the same time, since the limiting plate 25 abuts against the inner wall of the limiting groove 24, the shaking of the spiral rod 22 caused by the impact of the water flow on the spiral blades of the spiral rod 22 is reduced (it should be noted that in order to avoid the appearance of water flow blockage in the water guide column 21 due to the existence of the limiting plate 25, the limiting plate 25 needs to 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 is laid and a waterproof and thermal insulation layer is set up in the pool, water is injected into the pool through the water distributor 1, and the water in the pool is cooled by the refrigeration unit. Due to the presence of the waterproof and thermal insulation layer, the water temperature can be kept at a relatively low temperature. The water injection and cooling operations in the pool are performed at night to reduce the waste of electricity at night and reduce the use of electricity during peak hours.

[0061] Among them, since impurities in the water block the water outlet 23 of the water distributor 1, the water distributor 1 cannot spray water evenly, which may affect the cooling effect of the water in the pool. By setting a spiral rod 22 in the water guide column 21, when the water flows into the water guide column 21, the spiral blades of the spiral rod 22 drive the spiral rod 22 to rotate under the impact of the water flow, so that the water in the water guide column 21 flows circumferentially around the spiral rod 22, 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 flows into the water guide column 21 and drives the spiral rod 22 to rotate.

[0062] When the linkage block 331 rotates until the end of the arc groove 336 abuts against the limit rod 333, the linkage block 331 moves toward the screw rod 22 under the limit of the limit rod 333, and at the same time, the annular protrusion moves out of the annular groove to prevent the output shaft of the drive motor 32 from rotating for a long time under the impact of the water flow, thereby affecting the rotor and other structures in the drive motor 32. When 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 threadedly connected to the threaded rod 34 move away from the screw rod 22 under the limit of the limit rod 333, and the annular protrusion is re-engaged in the annular groove and abutted against the locking protrusion 352, so that the water distributor 1 can distribute water again.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
