Description

Technical Field

[0001] This invention belongs to the field of cross-seasonal thermal storage / heating design and construction, and in particular, a spliced ​​cross-seasonal hot water body top cover and its manufacturing method. Background Technology

[0002] Heating is a major energy consumer, and the transition from fossil fuel heating to zero-carbon heating is an inevitable trend. Cross-seasonal thermal storage technology serves as a bridge connecting waste heat with heating load. By rationally allocating the proportion of heating energy and establishing cross-seasonal heating projects using waste heat, the low-carbon and stable nature of winter heating can be achieved through "summer storage and winter use," which can significantly reduce carbon emissions.

[0003] In past cases of inter-seasonal heating projects, significant heat loss from the roof has been a key issue hindering the widespread application of inter-seasonal thermal storage technology. This heat loss is caused by many factors; previous cases often focused on selecting better insulation materials or increasing the thickness of the insulation layer, while neglecting the heat loss caused by the water accumulation pits within the roof.

[0004] Currently, most thermal insulation roofs used both domestically and internationally are still one-piece designs. The losses from leaks or damage to these roofs can be incalculable. Furthermore, most thermal insulation roofs do not consider drainage; during periods of heavy rainfall, puddles will form on these one-piece roofs, further increasing heat loss.

[0005] Both the 60,000 m³ hot water storage systems in Langkazi County, Tibet Autonomous Region, and Dronninglund, Denmark, employ integrated floating flexible roofs. Counterweight pipes are arranged from the perimeter towards the center of the roof to guide accumulated water to gather at the center under gravity, after which rainwater is manually pumped out. This method cannot drain water promptly, and damage to the roof can increase heat loss.

[0006] Chinese patent application CN201611050459.8 proposes a flexible floating roof for low-heat-loss hot water storage, relying on the buoyancy of water to support the top structure of the hot water storage body. Its structure consists of an upper honeycomb flexible membrane layer, a lower high-temperature resistant flexible membrane layer in direct contact with the water, and insulation material in between. The roof is lower than the ground and lacks rain protection measures; during heavy rain and continuous rainfall, water will accumulate at the center of the roof under gravity. If the upper honeycomb flexible membrane layer is damaged or water gets inside, it will be difficult to drain, leading to insulation failure of the roof.

[0007] Chinese patent application 202111645337.4 proposes a mortise and tenon joint type insulated load-bearing long-term solar water storage body roof. The roof consists of eight different structural modules, which are connected by mortise and tenon joints to form the entire roof, achieving its load-bearing function. However, this approach does not consider drainage, making efficient and timely drainage impossible. Furthermore, the complex and varied structural types result in poor insulation, and the mortise and tenon joints require the application of waterproof material over rigid insulation, making manufacturing inconvenient. Summary of the Invention

[0008] This invention provides a spliced, cross-seasonal hot water storage body top cover and its manufacturing method to solve the technical problems existing in the prior art. It has good heat preservation effect, simple structure, and is easy to manufacture and construct.

[0009] The present invention provides a technical solution to address the technical problems existing in the prior art: a spliced, cross-seasonal hot water storage body cover, comprising a cover body and an automatic drainage structure. The cover body is composed of multiple cover modules and multiple H-shaped components I connected together. Adjacent cover modules are connected by an H-shaped component I, the web of which is vertically arranged. The sides of two adjacent cover modules are respectively inserted into the two sides of the H-shaped component I. The two H-shaped components are connected. The sides of the cover body are inserted into a cover frame formed by H-shaped components II. Each cover module is composed of a high-temperature resistant waterproof membrane covering an insulation board. A drainage board is fixed on each cover module, the upper surface of which is higher than the H-shaped component II and the surrounding wall. The H-shaped component I has crisscrossing internal drainage channels formed on the main body of the top cover. The bottom of the internal drainage channels is formed by the upper flange of the H-shaped component I, and the sidewalls are formed by the sides of the drainage plates. The automatic drainage structure includes an external drainage ring channel, a drainage hopper, and a water collection tank. The external drainage ring channel is fixed around the opening in the water body and is located below the frame of the top cover. The drainage hopper is located below the external drainage ring channel and is connected to the water collection tank through a pipeline. Geotextile is covered on the main body of the top cover, and the edges of the geotextile are fixed in the anchoring trench, which is located around the opening in the water body. An exhaust pipe is provided on the main body of the top cover, passing through the geotextile, and a manual exhaust valve is provided on the exhaust pipe.

[0010] The H-shaped component II and the H-shaped component I adopt a split structure, with an inverted T-shaped main body and an upper flange plate. A slot extending longitudinally is provided in the center of the lower part of the upper flange plate, and the slot is fixed to the web plate of the inverted T-shaped main body.

[0011] Both H-shaped component II and H-shaped component I are made of high-density polyethylene.

[0012] The insulation board is made of composite rigid insulation material.

[0013] The drainage hopper is a siphon-type drainage hopper, and the external drainage ring groove is a siphon-type drainage groove.

[0014] Planting soil is laid on the geotextile, and plants are planted on it.

[0015] The drainage hopper is made of stainless steel or silicon-aluminum alloy and has an anti-corrosion layer. The air baffle and the baffle cover are integrally molded.

[0016] The drainage board adopts a concave-convex hollow rib structure and is made of polyethylene material.

[0017] Another technical solution adopted by the present invention to solve the technical problems existing in the prior art is: a method for manufacturing and constructing a spliced ​​cross-seasonal hot water storage body top cover as described above, which adopts the following steps: 1) prefabricate the top cover module in the factory and cut H-shaped component II and H-shaped component I; 2) construct the top cover frame and the top cover body in sequence on site; 3) install the automatic drainage structure; 4) cover the top cover body with geotextile and then anchor it.

[0018] It also includes step 5), where planting soil is laid on the geotextile and plants are planted in the planting soil.

[0019] The advantages and positive effects of this invention are:

[0020] 1) The top cover module adopts a splicing method, which effectively forms a whole and is not prone to deformation caused by land subsidence; the top cover module adopts H-shaped component connection, which can reduce the heat convection of the top cover from top to bottom and further improve the heat storage efficiency of the water body.

[0021] 2) The H-shaped components are made of high-density polyethylene, and the top cover module is made of composite rigid insulation material. Both have strong load-bearing capacity and are not easily deformed. Therefore, the top cover has load-bearing capacity, which can reduce the difficulty of construction, facilitate the maintenance and replacement of the top cover module, and allow plants to be planted on the top cover to protect the environment.

[0022] 3) The top cover module is connected by an H-shaped component. The H-shaped component adopts an upper and lower split structure, which facilitates the maintenance and replacement of the top cover module.

[0023] 4) It broadens the application range of top cover insulation materials. The use of composite insulation materials results in low cost and good insulation effect, which can improve the heat storage efficiency of hot water bodies.

[0024] 5) The top cover has a drainage channel inside, and the outer side of the frame uses a siphon drainage channel to remove rainwater in time. This can effectively reduce heat loss caused by water accumulation, prevent water from entering the insulation module and the insulation effect from failing due to severe weather, extend the service life of the insulation module, and reduce economic losses.

[0025] 6) It adopts zero-slope automatic drainage, which drains first and then prevents, combining drainage and prevention, resulting in high drainage efficiency and fast drainage speed.

[0026] 7) Planting soil is laid on the geotextile, and plants are planted. The rainwater discharged from the top cover module can be collected and used effectively, or directly supplied to the green plants laid on the top cover, which is more environmentally friendly and effectively improves the efficiency of land use.

[0027] 8) The spliced ​​top cover can be manufactured according to the actual situation after on-site survey. The size of the top cover module can be flexibly adjusted according to the size of the water body opening to adapt to various sizes and shapes of hot water storage bodies. Using top cover modules of the same size is easy to manufacture and install, which can improve construction efficiency and reduce manufacturing costs.

[0028] 9) The materials used in this invention are simple, low in cost, and have a long service life, which is conducive to its widespread application. Attached Figure Description

[0045] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0046] Please see Figures 1 to 16 A modular, cross-seasonal hot water storage cover, comprising a cover body and an automatic drainage structure.

[0047] The main body of the top cover is composed of multiple top cover modules 1 and multiple H-shaped components I connected together. There are two types of H-shaped components I with different lengths: the longer H-shaped component 19 and the shorter H-shaped component 20.

[0048] Two adjacent top cover modules are connected by an H-shaped component I. The web of the H-shaped component I is vertically arranged. The sides of the two adjacent top cover modules 1 are respectively inserted into the two sides of the H-shaped component I. The two H-shaped components I are connected by a safety locking structure 18, or a pin structure can be used for connection.

[0049] The edge of the main body of the top cover is fitted inside the top cover frame 3 formed by H-shaped component II. H-shaped component II is the same as H-shaped component I, and there are two types with different lengths: the longer H-shaped component 19 and the shorter H-shaped component 20. That is to say, both H-shaped component II and H-shaped component I are composed of the longer H-shaped component 19 and the shorter H-shaped component 20.

[0050] The top cover module 1 is composed of a high-temperature resistant waterproof membrane 14 covering a composite insulation board 15. A drainage board 2 is fixed on each top cover module 1. The upper surface of the drainage board 2 is higher than the H-shaped component II and the H-shaped component I. A crisscrossing internal drainage groove 4 is formed on the top cover body. The bottom of the internal drainage groove 4 is formed by the upper flange plate 16 of the H-shaped component I, and the sidewalls are formed by the sides of the drainage board 2.

[0051] The automatic drainage structure includes an external drainage ring groove 10, a drainage hopper 11, and a water collection tank 13. The external drainage ring groove 10 is fixed around the opening in the water body and is located below the top cover frame 3. The drainage hopper 11 is located below the external drainage ring groove 10 and is connected to the water collection tank 13 through a pipe 12.

[0052] Geotextile 7 is covered on the main body of the top cover, and the edges of the geotextile 7 are fixed in the anchoring trench 8, which is set around the opening in the water body.

[0053] An exhaust pipe 5 is provided on the main body of the top cover. The exhaust pipe 5 passes through the geotextile 7 and a manual exhaust valve 6 is provided on the exhaust pipe 5.

[0054] The aforementioned top cover uses two types of H-shaped components to connect the top cover module 1, which has a simple structure, few convection gaps, and can improve the thermal insulation effect. It is also simple to manufacture and easy to construct. The main body of the top cover forms a drainage channel 4, which is connected to an automatic drainage structure to remove rainwater in time, reduce water accumulation, and thus prevent water from entering the top cover module 1 and the failure of the thermal insulation effect. At the same time, it can extend the service life of the thermal insulation module 1 and reduce maintenance costs.

[0055] This embodiment also includes the following optimizations:

[0056] The H-shaped component II and the H-shaped component I adopt a split structure, with an inverted T-shaped main body 17 and an upper flange plate 16. A slot 9 extending longitudinally is provided in the center of the lower part of the upper flange plate 16, and the slot 9 is fixed to the web plate of the inverted T-shaped main body 17. When replacing the top cover module 1, the top cover module 1 can be installed and removed by removing the upper flange plate 16, which is convenient for maintenance.

[0057] The H-shaped component II and the H-shaped component I are made of high-density polyethylene, which has strong load-bearing capacity and is not easily deformed.

[0058] The insulation board is made of composite rigid insulation material 15, which broadens the application range of top cover insulation materials. Composite insulation materials can be used, further reducing the top heat loss, which accounts for the largest proportion of the heat storage body, improving the heat storage efficiency of the heat storage body while also saving costs. Please see below. Figure 12For a simulation of a hot water storage body with a top cover using composite rigid insulation material 15, please refer to [link / reference]. Figure 14 For a comparison of composite rigid insulation materials and single traditional insulation materials, including the longitudinal insertion of temperature probes into the hot water storage body, please refer to [link / reference needed]. Figure 15 and Figure 16 The analysis shows that the temperature was effectively reduced over time.

[0059] The drainage hopper 11 is a siphon-type drainage hopper, and the external drainage ring groove 10 is a siphon-type drainage groove. This allows rainwater or accumulated water to form a full flow state in the pipe even at a very shallow water depth. Utilizing the height of the top surface of the cover and the potential energy of the falling water, a partial vacuum is created in the pipe, giving the water flow in the drainage hopper 11 and the horizontal pipe additional pressure, thus forming a siphon effect. This siphon effect greatly accelerates the water flow velocity in the drainage pipe, quickly discharging rainwater or accumulated water from the top surface of the cover. The external drainage ring groove 10 uses zero-slope drainage, converting passive drainage into active drainage. It combines drainage with prevention, resulting in high drainage efficiency, fast drainage speed, and a stable and comprehensive siphon system that effectively discharges rainwater and accumulated water.

[0060] Planting soil is laid on the geotextile 7 and plants are planted, which greatly improves the land utilization rate. The planted vegetation can play a role in self-sufficiency, saving land and beautifying and protecting the environment.

[0061] The drainage hopper 11 is made of stainless steel or silicon-aluminum alloy and has an anti-corrosion layer. The air baffle and baffle cover are integrally molded. It has excellent anti-clogging effect, long service life, and can effectively and quickly drain accumulated water through the pipeline.

[0062] The drainage board 4 adopts a concave-convex hollow rib structure and is made of polyethylene. The concave-convex hollow rib structure can greatly reduce the hydrostatic pressure of the waterproof layer, drain accumulated water in time, and the use of polyethylene material has a long service life and low cost.

[0063] The above-mentioned method for fabricating and constructing the spliced ​​inter-seasonal hot water storage body cover adopts the following steps:

[0064] 1) Prefabricate the roof module and cut H-shaped component II and H-shaped component I in the factory;

[0065] 2) Construct the roof frame and roof body sequentially on site;

[0066] 3) Install an automatic drainage system;

[0067] 4) After covering the main body of the top cover with geotextile 7, anchor it.

[0068] It also includes step 5), where planting soil is laid on the geotextile 7, and plants are planted in the planting soil.

[0069] Although preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these modifications are within the scope of protection of the present invention.
