Description
Technical Field
[0001] This application relates to the field of water energy storage technology, and in particular to a diffuser and water energy storage device that are easy to assemble. Background Technology
[0002] As a core component of water storage systems, diffusers are widely used in water-based cooling (heat storage) air conditioning systems, significantly impacting the overall energy conversion efficiency. Water-based cooling (heat storage) air conditioning systems typically employ natural stratification for energy storage. The core characteristic of this method is the use of gravity to create natural stratification within the same storage container due to the density differences of water at different temperatures. The resulting temperature gradient layer, formed by the mixing of hot and cold water, acts as a separator between the cold and hot water zones. Both the energy storage and release processes utilize diffusers for water flow distribution. During these processes, it is crucial to minimize the disruption of temperature stratification by water flow and maximize the utilization of hot and cold water. Therefore, the design of the diffuser directly determines the performance of the water storage system.
[0003] Naturally stratified hydroelectric energy storage devices primarily utilize diffusers arranged at two different heights for water distribution. Water flows in and out through these diffusers. A key technical indicator for evaluating the quality of a hydroelectric energy storage device is the thickness of the thermocline layer formed at the interface between the hot and cold water during energy storage and release. A smaller ratio of the thermocline layer thickness to the total height of the storage container indicates better energy storage performance. Therefore, the design of the diffusers plays a crucial role in maximizing the effective utilization volume of the hydroelectric energy storage device. Currently, diffusers are prone to generating turbulence during water distribution, resulting in an unstable and thick thermocline layer, which hinders the improvement of the effective utilization volume and prevents efficient heat exchange. Furthermore, traditional diffusers are inconvenient to assemble, hindering rapid on-site assembly and consuming significant manpower. Utility Model Content
[0004] To address the aforementioned problems, this application provides a diffuser and water storage device that are easy to assemble. The design is ingenious and the structure is simple. This application achieves rapid assembly of the diffuser by sequentially fitting a baffle plate, support frame, and diffuser disc around the water guide pipe, and securing these three components between a retaining spring and the flange of a sealing plate, thus saving labor time. Furthermore, by creating water guide holes evenly spaced around the axis of the water guide pipe, the direction of water flow in and out of the pipe is restricted, ensuring that the water flows horizontally. This reduces the convective mixing effect of water at different temperature levels, avoids turbulence, and minimizes disturbance to stable water bodies. This reduces the disturbance and damage to the thermocline caused by water flow, facilitating the acquisition of a stable thermocline and increasing the effective utilization volume of the water storage device. This ensures efficient heat exchange in the water storage device. The technical solution adopted in this application is as follows:
[0005] A diffuser that is easy to assemble includes:
[0006] A water guide pipe has a thread at one end and a sealing plate fixed to the other end, which is then sealed by the sealing plate. Water guide holes are provided between the two ends of the water guide pipe, and the water guide holes are evenly spaced around the axis of the water guide pipe. The sealing plate has a flange protruding from the water guide pipe.
[0007] The diffuser and the baffle are provided with holes in the center of the diffuser and the baffle that are adapted to the water guide pipe.
[0008] The water guide pipe passes through the diffuser plate and the baffle plate, and the baffle plate abuts against the flange of the sealing plate; the outer periphery of the diffuser plate is a folded edge, and the folded edge is inclined towards the baffle plate; the diffuser plate and the baffle plate are supported by a support frame, which is sleeved on the water guide pipe; the water guide hole on the water guide pipe is located between the diffuser plate and the baffle plate; a retaining spring is snapped onto the water guide pipe, and the side of the diffuser plate away from the support frame abuts against the retaining spring.
[0009] By sequentially fitting the baffle plate, support frame, and diffuser plate onto the outside of the water guide pipe, and then securing these three components between the retaining spring and the flange of the sealing plate, rapid assembly of the diffuser is achieved, saving labor time. Furthermore, by creating water guide holes evenly spaced around the axis of the water guide pipe, the direction of water flow in and out of the pipe is restricted, ensuring horizontal flow. This reduces the convective mixing effect of water at different temperature levels, avoids turbulence, and minimizes disturbance to stable water bodies. This reduces the disturbance and disruption of the thermocline caused by water flow, facilitating the acquisition of a stable thermocline and increasing the effective utilization volume of the water storage device, ensuring efficient heat exchange.
[0010] In some embodiments, the support frame includes a first annular plate, a second annular plate, and a plurality of support columns, wherein the first annular plate and the second annular plate are arranged parallel to each other; one end of each support column is fixed to the first annular plate, and the other end is fixed to the second annular plate; the plurality of support columns are arranged circumferentially around the water guide pipe.
[0011] The first and second annular plates on the support frame ensure sufficient contact area between the support frame and the diffuser plate and the baffle plate, respectively. This allows the diffuser plate and baffle plate to be evenly stressed, reducing the risk of deformation or even damage to the diffuser plate and baffle plate during use. Furthermore, this type of support frame structure is stable and not easily deformed, providing stable support for the diffuser plate and baffle plate.
[0012] In some embodiments, the first annular plate and / or the second annular plate are in clearance fit with the water guide pipe.
[0013] By using the gap fit between the first and / or second annular plates and the water guide pipe, it can be ensured that the support frame is coaxial with the water guide pipe when it is sleeved outside the water guide pipe, thus avoiding the support frame and the water guide pipe being out of axis. This allows the diffuser plate and the baffle plate to be subjected to uniform force in the circumferential direction, further reducing the risk of deformation or even damage to the diffuser plate and the baffle plate during the use of the diffuser.
[0014] In some embodiments, the diffuser, the baffle, and the support frame are all injection molded from plastic.
[0015] The diffuser plate, baffle plate, and support frame are made of plastic injection molding. Compared with the diffuser plate, baffle plate, and support frame made of metal, this manufacturing method eliminates the need for stamping, milling, and welding, thereby reducing material costs, simplifying manufacturing, and improving production efficiency.
[0016] On the other hand, this application provides a water energy storage device, including a lower water distribution assembly, an upper water distribution assembly, and a water tank. The lower water distribution assembly and the upper water distribution assembly are each composed of a main water pipe, several branch water pipes, and several of the aforementioned diffusers. One end of each branch water pipe is connected to the main water pipe, and the other end is screwed to the water guide pipe of the diffuser. The lower water distribution assembly is located at the bottom of the inner cavity of the water tank, and the diffusers in the lower water distribution assembly face the bottom surface of the water tank. The upper water distribution assembly is located at the top of the inner cavity of the water tank, and the diffusers in the upper water distribution assembly face the top surface of the water tank.
[0017] The diffuser and water energy storage device provided in this application, which are easy to assemble, have at least one of the following beneficial effects:
[0018] 1. This application provides a diffuser that is easy to assemble. By sequentially fitting a baffle plate, a support frame, and a diffuser disc onto the outside of a water guide pipe, and securing the baffle plate, support frame, and diffuser disc between a retaining spring and the flange of a sealing plate, the diffuser can be quickly assembled, saving labor time. Furthermore, by opening water guide holes evenly spaced around the axis of the water guide pipe, the direction of water flow in and out of the water guide pipe is restricted, causing the water to flow horizontally in and out of the water guide pipe. This reduces the convection mixing effect of water at different temperature layers, avoids turbulence, and reduces disturbance to stable water bodies. This reduces the disturbance and damage to the thermocline caused by water flow, facilitating the acquisition of a stable thermocline and increasing the effective utilization volume of the water storage device, ensuring efficient heat exchange in the water storage device.
[0019] 2. The diffuser provided in this application is easy to assemble. Through the first and second annular plates on the support frame, it ensures sufficient contact area between the support frame and the diffuser plate and the baffle plate, respectively. This allows the diffuser plate and baffle plate to be evenly stressed, reducing the risk of deformation or even damage to the diffuser plate and baffle plate during use. Furthermore, this type of support frame structure is stable and not easily deformed, providing stable support for the diffuser plate and baffle plate.
[0020] 3. The diffuser provided in this application is easy to assemble. Through the gap fit between the first annular plate and / or the second annular plate and the water guide pipe, it can ensure that the support frame is coaxial with the water guide pipe when it is sleeved outside the water guide pipe. This can avoid the support frame and the water guide pipe being out of axis. This allows the diffuser plate and the baffle plate to be subjected to uniform force in the circumferential direction, further reducing the risk of deformation or even damage to the diffuser plate and the baffle plate during the use of the diffuser.
[0021] 4. The diffuser provided in this application is easy to assemble. It uses plastic injection molding to form a diffuser plate, a baffle plate and a support frame. Compared with the diffuser plate, baffle plate and support frame made of metal, this manufacturing method does not require stamping, milling and welding, which reduces material costs, reduces manufacturing difficulty and improves production efficiency.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.
[0031] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled.

[0032] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0033] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] refer to Figures 1-4 This application provides a diffuser that is easy to assemble, comprising: a water guide pipe 1, one end of which is provided with a thread 11, and the other end is fixedly connected to a sealing plate 12 and sealed by the sealing plate 12; water guide holes 13 are provided between the two ends of the water guide pipe 1, and the water guide holes 13 are evenly distributed around the axis of the water guide pipe 1; the sealing plate 12 has a flange 121 protruding from the water guide pipe 1; a diffuser plate 2 and a baffle plate 3, the center of the diffuser plate 2 and the center of the baffle plate 3 are provided with holes adapted to the water guide pipe 1;
[0036] The water guide pipe 1 passes through the diffuser plate 2 and the baffle plate 3, and the baffle plate 3 abuts against the flange 121 of the sealing plate 12; the outer periphery of the diffuser plate 2 is a folded edge 21, which is inclined towards the baffle plate 3; the diffuser plate 2 and the baffle plate 3 are supported by a support frame 4, which is sleeved on the outside of the water guide pipe 1; the water guide hole 13 on the water guide pipe 1 is located between the diffuser plate 2 and the baffle plate 3; a retaining spring 5 is snapped on the water guide pipe 1, and the side of the diffuser plate 2 away from the support frame 4 abuts against the retaining spring 5.
[0037] It is easy to understand that by sequentially fitting the baffle plate 3, support frame 4, and diffuser plate 2 onto the outside of the water guide pipe 1, and securing the baffle plate 3, support frame 4, and diffuser plate 2 between the retaining spring 5 and the flange 121 of the sealing plate 12, the diffuser is quickly assembled, saving time. Furthermore, by opening water guide holes 13 evenly spaced around the axis of the water guide pipe 1, the direction of water flow out of and into the water guide pipe 1 is restricted, causing the water to flow horizontally in and out of the water guide pipe 1. This weakens the convection mixing effect of water at different temperature layers, avoids turbulence, and reduces disturbance to stable water bodies. This reduces the disturbance and damage to the thermocline caused by water flow, facilitating the acquisition of a stable thermocline and increasing the effective utilization volume of the water storage device, ensuring efficient heat exchange.
[0038] In this embodiment, the presence of the diffuser plate 2 and the baffle plate 3 increases the horizontal water distribution coverage of the diffuser, thus reducing the number of diffusers required in the water storage device. Furthermore, the presence of the diffuser plate 2 and the baffle plate 3 further restricts the direction of water flow out of and into the water guide pipe 1, enhancing the effect of reducing convection mixing between waters at different temperature layers and further reducing the risk of disturbing stable water bodies. The presence of the folded edge 21 reduces the water flow velocity and the probability of turbulence. Moreover, the presence of the folded edge 21 ensures that the water flowing out of the water guide pipe 1 and passing through the folded edge 21 has a velocity component away from the thermocline, reducing the disturbance of the thermocline to the water flow.
[0039] refer to Figures 1-4 In one embodiment, the support frame 4 includes a first annular plate 41, a second annular plate 42, and a plurality of support columns 43. The first annular plate 41 and the second annular plate 42 are arranged parallel to each other. One end of the support column 43 is fixed to the first annular plate 41, and the other end is fixed to the second annular plate 42. The plurality of support columns 43 are arranged circumferentially around the water guide pipe 1.
[0040] It is worth noting that the first annular plate 41 and the second annular plate 42 on the support frame 4 ensure that the support frame 4 has sufficient contact area with the diffuser plate 2 and the baffle plate 3 respectively, so that the diffuser plate 2 and the baffle plate 3 are evenly stressed, reducing the risk of deformation or even damage to the diffuser plate 2 and the baffle plate 3 during the use of the diffuser. In addition, this type of structure of the support frame 4 is stable and not easily deformed, and can provide stable support for the diffuser plate 2 and the baffle plate 3.
[0041] refer to Figures 1-4 In one embodiment, the first annular plate 41 and / or the second annular plate 42 are in clearance fit with the water guide pipe 1. That is, at least one of the first annular plate 41 and the second annular plate 42 is in clearance fit with the water guide pipe 1. In other words, the inner diameter of at least one of the first annular plate 41 and the second annular plate 42 matches the outer diameter of the water guide pipe 1.
[0042] It is important to note that the gap fit between the first annular plate 41 and / or the second annular plate 42 and the water guide pipe 1 ensures that the support frame 4 is coaxial with the water guide pipe 1 when it is sleeved outside the water guide pipe 1, thus avoiding the support frame 4 and the water guide pipe 1 being out of axis. This allows the diffuser plate 2 and the baffle plate 3 to be subjected to uniform force in the circumferential direction, further reducing the risk of deformation or even damage to the diffuser plate 2 and the baffle plate 3 during the use of the diffuser.
[0043] It is worth noting that in this application, the diffuser plate 2, the baffle plate 3, and the support frame 4 are preferably made of plastic injection molding. Compared with the fact that all components of the traditional diffuser are made of metal, the use of plastic injection molding for the diffuser plate 2, the baffle plate 3, and the support frame 4 eliminates the need for stamping, milling, and welding, thereby reducing material costs, simplifying manufacturing, and improving production efficiency.
[0044] refer to Figure 5 This application also provides a water energy storage device, including a lower water distribution assembly, an upper water distribution assembly, and a water tank 8. Both the lower and upper water distribution assemblies consist of a main water pipe 6, several branch water pipes 7, and several of the aforementioned diffusers. One end of each branch water pipe 7 is connected to the main water pipe 6, and the other end is screwed to the guide pipe 1 of the diffuser. The lower water distribution assembly is located at the bottom of the inner cavity of the water tank 8, with the diffusers in the lower water distribution assembly facing the bottom surface of the water tank 8. The upper water distribution assembly is located at the top of the inner cavity of the water tank 8, with the diffusers in the upper water distribution assembly facing the top surface of the water tank 8. The specific structure of the diffusers in this water energy storage device is as described in the foregoing embodiments. Since this water energy storage device adopts the technical solutions of the foregoing embodiments, it at least possesses the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated further here.
[0045] The lower water distribution assembly is used to input or output relatively low-temperature water, such as water temperature less than 5°C; the upper water distribution assembly is used to input or output relatively high-temperature water, such as water temperature greater than 12°C. Because the density of low-temperature water is greater than that of high-temperature water, natural stratification occurs in the water tank 8, forming two constant-temperature layers 9 and an inclined temperature layer 10 located between the two constant-temperature layers 9. The constant-temperature layer 9 above the inclined temperature layer 10 contains high-temperature water; the constant-temperature layer 9 below the inclined temperature layer 10 contains low-temperature water. The smaller the thickness of the inclined temperature layer 10, the better the energy storage effect of the water energy storage device. Water flow disturbance will cause the thickness of the inclined temperature layer to increase. By using the diffuser in this application, water flow disturbance can be reduced during operation, effectively improving the energy utilization rate of the water energy storage device.
[0046] The working principle of this water storage energy device is as follows:
[0047] When the water storage device stores heat or releases cold, the external heat exchange device or load injects water with high temperature and low density into the upward water distribution component, causing the inclined temperature layer 10 to move downward, and water with low temperature and high density is output from the lower water distribution component.
[0048] When the water storage device stores cold or releases heat, the external heat exchange device or load injects water with low temperature and high density into the downward water distribution component, causing the inclined temperature layer 10 to move upward, and water with high temperature and low density is output from the upper water distribution component.
[0049] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
