Description

Technical Field

[0001] The invention belongs to the field of cross-season heat storage / heat supply design and construction, and in particular to a spliced ​​cross-season hot water storage body top cover and a manufacturing method thereof. Background Art

[0002] Heating is a major energy consumer, and the transition from fossil energy heating to zero-carbon heating is an inevitable trend. Inter-seasonal heat storage technology is a bridge between waste heat and heating load. It rationally allocates the proportion of heating energy, establishes an inter-seasonal heating project for waste heat, and realizes low-carbon and stable winter heating through "summer storage and winter use", which can significantly reduce carbon emissions.

[0003] In the past cases of inter-seasonal heating projects, the heat loss of the roof is relatively large, which has always been a key issue restricting the promotion and application of inter-seasonal heat storage technology. The heat loss of the roof is caused by many factors. In previous cases, insulation materials with better thermal insulation effects or increasing the thickness of the insulation layer were often selected, while the heat loss caused by the accumulation of water puddles on the roof was ignored.

[0004] At present, the insulation roof used at home and abroad is mainly one-piece. Once the roof leaks or is damaged, the loss will be immeasurable. Moreover, most of the insulation roofs at home and abroad do not consider drainage. Once there is a lot of rainfall, many puddles will appear on the one-piece roof, which will undoubtedly increase the heat loss.

[0005] Langkazi County, Tibet, my country and Dronninglund, Denmark 60000m 3 The hot water storage bodies all use an integrated floating flexible cover, and the weight pipes are arranged on the upper surface of the cover from the periphery to the center, guiding the accumulated water to gather in the center of the cover under the action of gravity, and then manually start the water pump to drain the rainwater. This method cannot drain water in time, and once the cover is damaged, it will increase heat loss.

[0006] Chinese patent application CN201611050459.8 proposes a flexible floating roof for a low heat loss water storage body, which relies on the buoyancy of water to support the top structure of the water storage body. Its structure is an upper honeycomb flexible membrane layer, a lower layer is a high temperature resistant flexible membrane layer in direct contact with the water body, and a thermal insulation material is arranged in the middle. The top cover is lower than the ground and no rain protection measures are taken. In heavy rain and continuous rainfall, the accumulated water will gather in the center of the top cover under the action of gravity. Once the upper honeycomb flexible membrane layer is damaged or water is difficult to drain after entering, it will cause the insulation of the top cover to fail.

[0007] Chinese patent application 202111645337.4 proposes a mortise-jointed heat-insulating and load-bearing long-cycle solar cross-seasonal hot water storage body roof. There are eight structural forms of the modules that make up the roof. The eight structural forms of modules are connected by mortise and tenon to form a roof as a whole, which can realize the load-bearing function of the roof. However, this approach does not consider the drainage problem, and it is impossible to drain water at any time and efficiently. In addition, the structure types are complex and changeable, the insulation effect is poor, and the production of the mortise and tenon interface requires the laying of waterproof materials on the hard insulation material, which is inconvenient to manufacture.

[0046] See also Figures 1 to 16 , a spliced ​​cross-seasonal hot water storage body cover, including a cover body and an automatic drainage structure.

[0047] The top cover body is formed by connecting a plurality of top cover modules 1 and a plurality of H-shaped components Ⅰ. The H-shaped components Ⅰ have two different lengths, a longer H-shaped component 19 and a 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, and the edges of the two adjacent top cover modules 1 are respectively plugged into the inside of the two sides of the H-shaped component Ⅰ. The two butt-jointed H-shaped components Ⅰ are connected and connected by a safety lock structure 18, and can also be connected by a pin structure.

[0049] The edge of the top cover body is inserted into the top cover frame 3 surrounded by the H-shaped member II. The H-shaped member II is the same as the H-shaped member I, and also has two different lengths, a longer H-shaped member 19 and a shorter H-shaped member 20, that is, the H-shaped member II and the H-shaped member I are both composed of a longer H-shaped member 19 and a shorter H-shaped member 20.

[0050] The top cover module 1 is composed of a composite insulation board 15 covered with a high-temperature resistant waterproof membrane 14. A drainage board 2 is fixed on each of the top cover modules 1. The upper surface of the drainage board 2 is higher than the H-shaped component II and the H-shaped component I. A criss-crossing internal drainage groove 4 is formed on the top cover body. The bottom of the internal drainage groove 4 is composed of the upper flange plate 16 of the H-shaped component I, and the side wall is composed of the side of the drainage board 2.

[0051] The automatic drainage structure includes an external drainage ring groove 10, a drainage bucket 11 and a water collecting box 13. The external drainage ring groove 10 is fixed around the opening on the water body and arranged below the top cover frame 3. The drainage bucket 11 is arranged below the external drainage ring groove 10 and is connected to the water collecting box 13 through a pipeline 12.

[0052] The top cover body is covered with a geotextile 7, the edges of which are fixed in an anchoring trench 8, and the anchoring trench 8 is arranged around the opening on the water body.

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

[0054] The top cover uses two H-shaped components to connect the top cover module 1, which has a simple structure, few convection gaps, can improve the insulation effect, and is simple to make and easy to construct. A drainage groove 4 is formed inside the top cover body and connected to the automatic drainage structure, which can drain rainwater in time and reduce water accumulation, thereby preventing the top cover module 1 from getting water in and the insulation effect from failing, and at the same time can extend the service life of the insulation module 1 and reduce maintenance costs.

[0055] This embodiment is also optimized as follows:

[0056] The H-shaped member II and the H-shaped member I adopt a split structure, and are provided with an inverted T-shaped body 17 and an upper flange plate 16. A slot 9 extending longitudinally thereof is centrally provided below the upper flange plate 16, and the slot 9 is fixed to the web of the inverted T-shaped 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 repair and maintenance.

[0057] The H-shaped component II and the H-shaped component I are made of high-density polyethylene, have strong load-bearing capacity and are not easy to deform.

[0058] The insulation board is made of composite hard insulation material 15, which broadens the application scope of the top cover insulation material. Composite insulation material can be used, further reducing the top heat loss which accounts for the largest proportion of the hot water storage body, improving the heat storage efficiency of the hot water storage body and saving costs. Fig.12For simulation of a hot water storage body with a roof made of composite rigid insulation material 15, see Fig.14 Add a temperature probe to the water storage body longitudinally. Compare the composite hard insulation material with the single traditional insulation material. Please refer to Fig.15 and Fig.16 ,The analysis shows that the temperature variation over time has been ,effectively reduced.

[0059] The drainage bucket 11 adopts a siphon drainage bucket, and the external drainage ring groove 10 adopts a siphon drainage groove, so that rainwater or accumulated water can form a full flow state in the pipeline at a very shallow water depth. The height of the top cover and the potential energy of the falling water are used to create a local vacuum in the pipeline, so that the water flow in the drainage bucket 11 and the horizontal pipe obtains additional pressure to form a siphon phenomenon. The siphon effect is used to greatly accelerate the flow rate of water in the drainage pipe, and quickly discharge rainwater or accumulated water on the top cover. The external drainage ring groove 10 adopts zero slope drainage, converting passive drainage into active drainage, first drainage and then prevention, prevention and drainage are combined, the drainage efficiency is high, the drainage speed is fast, and the stable and comprehensive system siphon achieves the purpose of discharging rainwater and accumulated water.

[0060] Planting soil is laid on the geotextile 7 to plant plants, which greatly improves the utilization rate of the land. The planted vegetation can play the role of self-sufficiency, land saving and beautification of the environment.

[0061] The drainage bucket 11 is made of stainless steel or silicon aluminum alloy, and is provided with an anti-corrosion layer, and the air baffle and the baffle cover are integrally formed. It has a good anti-blocking effect, a long service life, and can effectively and quickly discharge accumulated water through the pipeline.

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

[0063] The manufacturing and construction method of the above-mentioned spliced ​​cross-seasonal hot water storage body top cover adopts the following steps:

[0064] 1) Prefabricate the top cover module and cut the H-shaped member II and H-shaped member I in the factory;

[0065] 2) Construct the top cover frame and top cover body in sequence on site;

[0066] 3) Install automatic drainage structure;

[0067] 4) Cover the top cover body with geotextile 7 and then anchor it.

[0068] The method further comprises step 5), laying planting soil on the geotextile 7 and planting plants on the planting soil.
