Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a cold water storage tank with an automatic drainage function. Background Art
[0002] Water storage air conditioner uses energy storage equipment to open the cold (heat) source equipment to produce energy during the off-peak period of electricity consumption (low electricity price period) and store it in the form of low (high) temperature water. During the peak period of electricity consumption in the daytime (high electricity price period), it fully utilizes the energy stored at night to provide cooling (heating) and does not open or opens less cold (heat) source equipment, thereby achieving the purpose of shifting the peak power to fill the valley. From a macro perspective, energy storage air conditioner can balance the load of the national or regional power grid, give full play to the efficiency of power generation equipment, and thus reduce the installed capacity of power stations and reduce the capital investment of the national power grid; from the micro perspective of users, it can save a lot of air conditioning operating costs by using the peak-valley electricity price difference. Depending on the different storage capacity of the system, it can save 30%-70% of the operating costs, and can also reduce the grid access capacity and reduce the air conditioning power capacity by 30%-50%, solving the problem of power shortage and saving the initial investment in electricity.
[0003] In water storage technology, the key issue is that the structure of the water tank should be able to prevent the mixing of the stored cold water and the return hot water. The natural stratification method uses the different densities of water at different temperatures to achieve natural stratification, and is currently widely used. In the summer cold storage cycle, the cold water sent by the chiller enters the water tank through the water distributor at the bottom of the water tank, while the hot water in the original water tank flows out from the water distributor at the top of the water tank and enters the chiller for cooling. As the volume of cold water increases, the inclined temperature layer at the junction of cold and hot water in the water tank will be pushed upward, while the total water volume in the water tank remains unchanged; in the cooling cycle, the water flows in the opposite direction, and the cold water is pumped out from the lower water distributor by the cooling pump and sent to the user, and the water with a higher temperature after heat exchange enters the water tank from the upper water distributor. The principle of heat storage in winter is the same as that of cold storage, except that the working temperature range of the medium water is larger.
[0004] The common water storage tank structures of existing water storage air conditioners can be divided into steel water storage tanks and reinforced concrete water storage tanks. In order to reduce the floor space, water storage tanks are mostly built in the basement of buildings and are set near the refrigeration room for energy storage and release. In addition, the water storage tank with underground reinforced concrete structure needs to add insulation layer, waterproof layer and protective layer inside to ensure that the energy of the stored cold water will not be lost. The common specific construction method is: base treatment → polymer waterproof and moisture-proof layer → polyurethane foam insulation layer → leveling layer → polyurea waterproof layer.
[0005] At present, the cold water storage tanks built with existing technology are located in the basement of the building. Some cold water storage tanks are built on the edge of the building structure, so that the bottom or wall of the tank will be in contact with the underground soil. If the structural waterproofing is not done well, it will cause leakage and seepage problems inside the cold water storage tank. Especially in coastal cities and rainy seasons, this problem is more frequent. Once this problem occurs, it will affect the normal construction of the subsequent cold water storage tank, and it is necessary to repair the leakage points in the cold water storage tank, but the effect of this repair operation is not ideal and it takes a lot of time. Once it rains later, new leakage points will appear. If this situation is not handled or handled imperfectly, the insulation layer will fall off and be damaged due to long-term seepage and leakage, which will make the function of the entire cold water storage tank ineffective and cause huge losses to users.

[0024] Please refer to Figure 1 , which is a cross-sectional view of the elevation structure of the pool wall of a cold water storage pool with automatic drainage function provided by an embodiment of the utility model.
[0025] The utility model provides a cold water storage pool with automatic drainage function, comprising a pool wall, wherein the pool wall comprises a side wall and a bottom wall, a hydrophobic layer is arranged on the surface of the pool wall, the hydrophobic layer completely covers the pool wall, and the hydrophobic layer is connected to a drainage outlet through a pipeline.
[0026] Specifically, the side wall refers to the side of the cold water storage tank, or the pool wall. The bottom wall refers to the bottom surface of the cold water storage tank, or the pool bottom.
[0027] Specifically, the function of the hydrophobic layer is to make water form water droplets on the surface and reduce surface friction. In conjunction with the pipe and the drain, the hydrophobic layer can help water flow along a predetermined path and be discharged smoothly from the cold water storage tank, thereby ensuring the drainage effect of the cold water storage tank. The predetermined path can be designed according to the needs of the site, and the water can be discharged from the drain along the hydrophobic layer and the pipe; or a hydrophobic texture can be set on the surface of the hydrophobic layer. The hydrophobic texture has a microscopic concave and convex surface, which can affect the flow direction and speed of water, so that the water rolls on the surface of the hydrophobic layer, and then the water is quickly discharged in conjunction with the pipe and the drain to achieve the drainage effect.
[0028] The cold water storage tank with automatic drainage function provided in this embodiment completely covers the pool wall with a hydrophobic layer to form a completely waterproof barrier to the pool wall, which can effectively prevent moisture from penetrating through the pool wall, improve the waterproofness of the cold water storage tank, and greatly reduce the possibility of water seepage and leakage inside the cold water storage tank due to contact with underground soil; and such a design can also allow moisture to be automatically discharged through the drain outlet along the hydrophobic layer and the pipeline, effectively ensuring that there is no water accumulation in the hydrophobic layer, further improving the reliability and safety of the cold water storage tank, and preventing groundwater leakage from affecting the thermal insulation performance of the cold water storage tank.
[0029] In some embodiments of the present application, the hydrophobic layer includes a plurality of hydrophobic plates 1, and all the hydrophobic plates 1 are spliced together to completely cover the pool wall.
[0030] Specifically, the hydrophobic board 1 is a board having hydrophobic properties and is generally used in waterproofing projects.
[0031] Specifically, a plurality of hydrophobic plates 1 are covered together on the pool wall to form a waterproof barrier, which can effectively reduce the impact of water flow on the pool wall and improve the stability and durability of the pool wall.
[0032] In some embodiments of the present application, the hydrophobic plate 1 is fixed to the pool wall via a mechanical anchor 2 .
[0033] Specifically, the mechanical anchor 2 is a mechanical device for fixing and supporting the structure, which is usually used in concrete, brick walls or other solid materials. They provide reliable support and fixation by forming a mechanical connection in the substrate. The mechanical anchor 2 is usually composed of components such as bolts, expansion tubes, nuts, etc., and forms a firm connection in the substrate through expansion or other mechanical principles to fix various structural parts. The hydrophobic plate 1 is fixed to the pool wall by the mechanical anchor 2, and the structure is stable and safe.
[0034] In some embodiments of the present application, a drain pipe 3 is provided at the joint between any two of the drain plates 1 , and the drain plates 1 are connected to the drain outlet via the drain pipe 3 .
[0035] Specifically, the surface of the hydrophobic plate 1 has a hydrophobic property, and moisture will flow along the surface and eventually gather at the joints. The hydrophobic pipe 3 is arranged at the joints between the hydrophobic plates 1 to remove moisture that may accumulate at the joints and prevent water seepage and leakage in the cold water storage tank due to water retention. The hydrophobic pipe 3 can effectively remove moisture, help keep the hydrophobic plate 1 dry and stable, improve the waterproof effect, and reduce the risk of water seepage and leakage in the cold water storage tank.
[0036] In some embodiments of the present application, a drain collector 4 is arranged around the junction of the side wall and the bottom wall, the water inlet end of the drain collector 4 is connected to the drain pipe 3, the water outlet end of the drain collector 4 is connected to the drain outlet, and the drain plate 1 is connected to the drain outlet through the drain pipe 3 and the drain collector 4 in turn.
[0037] Specifically, the drain header 4 is arranged on the bottom wall, and the water in all the drain pipes 3 can be smoothly gathered in the drain header 4 by utilizing gravity.
[0038] In some embodiments of the present application, the side wall is provided with a water storage riser 5, a drainage riser 6 and the drainage pump 8, the drainage riser 6 and the drainage pump 8 are located inside the water storage riser 5, the water inlet end of the water storage riser 5 is connected to the drain header 4, the water outlet end of the water storage riser 5 is connected to the water inlet end of the drainage riser 6 through the drainage pump 8, and the drain plate 1 is connected to the drain outlet through the drain pipe 3, the drain header 4, the water storage riser 5, the drainage pump 8 and the drainage riser 6 in sequence.
[0039] Specifically, the water storage riser 5 is used to collect water in the drain header 4. The drainage riser 6 is arranged inside the water storage riser 5 to facilitate drainage operation and maintenance. By arranging the drainage riser 6, the position of the drain outlet can be designed to be more convenient for operation and cleaning, making drainage more convenient and quick. In addition, the drainage riser 6 can also help control the drainage speed and drainage volume, avoiding the problem of poor drainage or too fast drainage due to direct drainage through the water storage riser 5. In addition, the drainage riser 6 can also reduce the amount of water accumulated inside the water storage riser 5, reduce maintenance costs and extend the service life of the cold water storage tank.
[0040] In some embodiments of the present application, a liquid level sensor 7 is further provided in the water storage riser 5 , and the liquid level sensor 7 is electrically connected to the drainage pump 8 .
[0041] Specifically, the water storage riser 5, the drainage pump 8, the liquid level sensor 7 and the drainage riser 6 together form a drainage system for draining the water in the water storage riser 5. The drainage operation is as follows: the liquid level sensor 7 detects the water level in the water storage riser 5. When the water level reaches the set value, the liquid level sensor 7 sends a signal to the automatic control system. After the automatic control system receives the signal from the liquid level sensor 7, it starts the drainage pump 8. The drainage pump 8 starts to work and pumps out the water in the water storage riser 5. The pumped water is sent to the drainage riser 6 through the drainage pump 8. The drainage riser 6 discharges the water sent by the drainage pump 8 to complete the drainage operation. Through the coordinated work of the liquid level sensor 7, the drainage pump 8 and the drainage riser 6, the automatic drainage operation of the water storage riser 5 can be realized, and the drainage efficiency and convenience are improved.
[0042] In some embodiments of the present application, a mortar layer is disposed on the surface of the hydrophobic layer, and the mortar layer completely covers the hydrophobic layer.
[0043] Specifically, the mortar layer can fill and seal the cracks and gaps in the hydrophobic layer to prevent moisture penetration, thereby playing a further role in waterproofing and moisture-proofing. It can also increase the impact resistance of the hydrophobic layer, reduce the impact of external impact on the structure of the hydrophobic layer, and improve the durability and safety of the hydrophobic layer. The mortar layer can also play a certain role in thermal insulation, reduce heat conduction, and improve the energy efficiency performance of the cold water storage tank.
[0044] In some embodiments of the present application, a thermal insulation layer and a waterproof layer are sequentially provided on the surface of the mortar layer, the thermal insulation layer completely covers the mortar layer, and the waterproof layer completely covers the thermal insulation layer.
[0045] Specifically, the thermal insulation layer of the cold water storage tank mainly plays the role of thermal insulation. It can reduce the loss of cooling water temperature inside the cold water storage tank, prevent heat from being conducted outward, improve the thermal insulation effect of the cold water storage tank, ensure that the stored cold water maintains a lower temperature, and reduce energy consumption.
[0046] Specifically, the waterproof layer of the cold water storage tank mainly plays the role of preventing water penetration. It can effectively prevent groundwater or external moisture from penetrating into the cold water storage tank, maintain the sealing of the cold water storage tank, prevent moisture from corroding the structural materials, and ensure the safe and stable operation of the cold water storage tank.
[0047] Specifically, the cold water storage tank is inspected before construction. If multiple leakage points are found in the cold water storage tank, a hydrophobic layer can be added before the construction of the cold water storage tank. The hydrophobic layer adopts a hydrophobic plate 1 and is fixed to the tank wall and the bottom by mechanical anchors 2. A hydrophobic pipe 3 is set at the joint between the hydrophobic plates 1, and the water flow at the wall leakage can flow to the hydrophobic pipe 3. The hydrophobic pipe 3 is connected to the hydrophobic header 4 at the bottom of the cold water storage tank, and the water flow in the hydrophobic pipe 3 flows into the hydrophobic header 4 at the bottom. The hydrophobic header 4 is also connected to the water storage riser 5, and the water flow in the hydrophobic header 4 flows into the water storage riser 5. The drainage pump 8, the liquid level sensor 7 and the drainage riser 6 are set in the water storage riser 5, and the drainage pump 8 is connected to the drainage riser 6. The drainage pump 8 extracts the water in the water storage riser 5 and discharges it to the drainage ditch outside the cold water storage tank through the drainage riser 6. Specifically: when the liquid level sensor 7 in the water storage riser 5 detects that the amount of water leakage reaches the set drainage height, the automatic control system turns on the drainage pump 8 to drain water; when the liquid level sensor 7 in the water storage riser 5 detects that the amount of water discharged reaches the set drainage height, the automatic control system turns off the drainage pump 8 to stop drainage. After all the above work is completed, a mortar layer is constructed on the upper part of the hydrophobic layer, and then the insulation layer and waterproof layer of the cold water storage tank are constructed. This not only solves the problem of water leakage and seepage in the cold water storage tank affecting normal construction, but also avoids the hidden danger of leakage in the cold water storage tank seriously damaging the insulation layer when the rainy season comes in the later use stage.
[0048] The cold water storage tank with automatic drainage function provided in the present embodiment adds a hydrophobic layer on the basis of the conventional cold water storage tank. The hydrophobic layer can be fixed to the tank wall and the tank bottom by a hydrophobic plate 1 using a mechanical anchor 2. A hydrophobic pipe 3 is arranged at the joint between the hydrophobic plates 1. The hydrophobic pipe 3 is connected to the hydrophobic header 4. The hydrophobic header 4 is connected to the water storage riser 5. A drainage pump 8, a liquid level sensor 7 and a drainage riser 6 are arranged in the water storage riser 5. The drainage pump 8 is connected to the drainage riser 6. After the above construction is completed, a mortar layer is constructed on the upper part of the hydrophobic layer, thereby solving the problem of water seepage and leakage in the existing cold water storage tank due to contact with underground soil, and further extending the service life of the cold water storage tank.
[0049] It should be noted that the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0050] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
