Description

Technical Field

[0001] The utility model belongs to the technical field of grain storage, and specifically relates to a shallow silo integrating photovoltaic power generation and waterproof and heat insulation. Background Technique

[0002] A shallow silo, also known as a low silo, is a special building for storing grain, and is a common cylindrical above-ground granary with the ratio of the silo height to the diameter less than 1.5.

[0003] The roofs of existing grain silos mostly adopt pitched roof designs considering structural stability and drainage, resulting in a relatively larger surface area of the silo top compared to a flat surface. Moreover, since the silo is directly exposed to sunlight, the temperature inside the silo rises, accelerating the aging speed of the silo and also affecting the quality stability of the stored grain inside the silo.

[0004] In this regard, the utility model patent CN220790770U discloses a shallow silo top integrating photovoltaic power generation and ventilation. The upper roof is designed as a flat surface, and a solar power generation panel is fixedly installed on its upper surface. A drainage mechanism is arranged on the low wall below the upper roof. The drainage mechanism includes a drainage ring groove fixedly installed on the low wall, and a plurality of water outlets are spaced apart on the drainage ring groove. Although a drainage mechanism is provided, the silo top is flat, which still affects the drainage efficiency. At the same time, the drainage structure is located on the low wall of the silo top rather than the silo top, and the seepage of the upper roof still cannot be drained in time, and there is a lack of effective protection of the silo wall against sunlight.

[0005] In this regard, the utility model patent CN215957245U discloses a concealed cooling device for the silo top based on a solar panel support in a grain depot. A plurality of connecting brackets are arranged on the top of the shallow silo, and a plurality of installation spaces are formed between the plurality of connecting brackets. Solar panels are arranged in the installation spaces. The connecting brackets include horizontal brackets, and the horizontal brackets also include vertical brackets. The vertical brackets are fixed on the silo top of the shallow silo through suction cups. The vertical brackets leave a gap between the solar panels and the silo top to achieve external isolation. Although the inclined design of the silo top and the installation of solar panels on the silo top are realized, the connecting brackets and the interlayer between the silo top and the outside are isolated, and the ventilation and heat dissipation ability is poor. At the same time, the stability of the suction cup fixation will be affected over time, and there is still a lack of effective protection of the silo wall against sunlight. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to realize power generation, waterproofing and heat insulation of the shallow silo through the added silo top and curtain wall of the shallow silo. In view of the deficiencies of the prior art, a shallow silo integrating photovoltaic power generation and waterproofing is provided.

[0007] To solve the above technical problems, the technical solution adopted by the utility model is:

[0008] An integrated shallow silo for photovoltaic power generation and waterproof and heat insulation, comprising a shallow silo, a curtain wall and a photovoltaic glass silo roof. The curtain wall is vertically installed on the outer wall of the shallow silo, and the photovoltaic glass silo roof is covered and installed on the inclined cone area of the shallow silo roof.

[0009] Further, the upper part of the photovoltaic glass silo roof is in the shape of a frustum of a cone, and the lower part is in the shape of a cylinder.

[0010] Further, an air inlet and an air outlet are respectively installed at the bottom and the top of the photovoltaic glass silo roof.

[0011] Further, both the air inlet and the air outlet have a height of 0.5 m.

[0012] Further, the curtain wall is located in the area 10 meters downward from the bottom of the eaves of the shallow silo body, and there is a ventilation gap between the curtain wall and the shallow silo body.

[0013] Further, the curtain wall is a photovoltaic glass curtain wall or an aluminum gusset curtain wall.

[0014] Further, a plurality of drain outlets are provided at the edge of the shallow silo roof.

[0015] An integrated shallow silo for photovoltaic power generation and waterproofing, with an inclined photovoltaic glass silo roof installed on the roof, and an independent air inlet is provided at the bottom of the photovoltaic silo roof. In addition to the ventilation function, this air inlet also has the function of draining the accumulated water that has penetrated through the photovoltaic glass silo roof, and cooperates with the existing drain outlets on the lower shallow silo roof to further improve the drainage capacity of the silo roof structure.

[0016] When installing the curtain wall on the wall of the shallow silo, the installation position and the height of the curtain wall need to be considered. While maximizing the coverage area, the cost and the balanced distribution of the curtain wall quality need to be taken into account to prevent affecting the inherent structural stability of the shallow silo. Therefore, the aluminum gusset curtain wall and the photovoltaic glass curtain wall can be installed in cooperation.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] Compared with the prior art, an integrated shallow silo for photovoltaic power generation and waterproofing provided by the present utility model, by fixedly installing an inclined triangular stable structure of the photovoltaic glass silo roof and reserving air inlets and outlets at the upper and lower parts of the silo roof, enables the silo roof to absorb heat by using photovoltaic power generation or receive rain and snow while timely relieving the heat accumulated between the glass silo roof and the silo roof of the silo.

[0019] The air inlet of the photovoltaic glass silo roof and the existing drain outlets on the shallow silo roof can timely drain the accumulated water that has penetrated through the upper photovoltaic glass silo roof, improving the waterproof performance of the shallow silo.

[0020] The top-down installed photovoltaic glass curtain wall or aluminum gusset curtain wall can be optionally installed according to the solar energy utilization rate on the premise of protecting the shallow silo from direct sunlight. At the same time, the installation interval of the curtain wall takes into account the installation effect and cost, and has good practicability and economy. Brief Description of the Drawings

[0028] Embodiment 1

[0029] Refer to Figures 1 - 3, including a shallow silo 1, a curtain wall, an air inlet 102, a photovoltaic glass silo top 103 and an air outlet 104. The curtain wall is vertically installed on the outer wall of the shallow silo 1. The curtain wall is a photovoltaic glass curtain wall 101. There is a ventilation gap between the curtain wall and the wall of the shallow silo 1. The photovoltaic glass silo top 103 is covered and installed on the inclined cone area of the top of the shallow silo 1. The upper part of the photovoltaic glass silo top 103 is in the shape of a frustum of a cone, and the lower part is in the shape of a cylinder. The air inlet 102 and the air outlet 104 are respectively installed at the bottom and top of the photovoltaic glass silo top 103, and the heights of both the air inlet 102 and the air outlet 104 are 0.5 m. There are several drain outlets at the edge of the top of the shallow silo 1.

[0030] The common height of a shallow silo is 25 m. A working height of 10 m and a height for dust dispersion of 5 m are reserved from bottom to top at the bottom. The remaining is the installation height range of the curtain wall. Considering the shading effect of adjacent shallow silos on sunlight, the photovoltaic glass curtain wall 101 is installed in the area of the wall of the shallow silo 1 from the bottom of the eaves to 10 meters downward.

[0031] This solution is mainly applicable to shallow silos in solar resource regions of Class I, Class II and Class III. It has better effects in high-temperature and rainy regions. Taking a shallow silo with a diameter of 30 m and storing 10,000 tons of soybeans in Zhenjiang area as an example, the total surface area of a single silo is about 1,950 square meters, and the proposed additional cost is 1.75 million yuan. The effective installation area of photovoltaic for a single shallow silo is about 660 square meters, the power generation per square meter is 275 kWh / year, the power generation of a single silo is 180,000 kWh / year, which is equivalent to 23.2 tons of standard coal, and the annual carbon emission reduction of a single silo is 51.27 tons. The local grid purchase price is about 0.7 yuan / kWh (to be determined), and the total comprehensive income is 126,000 yuan / year. At the same time, it can greatly reduce the usage frequency of the grain surface air-conditioning units on the top of the shallow silo, reduce the air-conditioning energy consumption by 8,500 kWh / year, the comprehensive electricity price is about 0.7 yuan / kWh, and the operating cost is saved by 5,950 yuan / year.

[0032] The technical solution provided by the embodiment of the present application, by installing a photovoltaic glass silo top with an inclined triangular stable structure and reserving air inlets and outlets at the upper and lower parts of the silo top, enables the silo top to absorb heat or receive rain and snow through photovoltaic power generation while timely relieving the heat accumulated between the glass silo top and the silo top of the silo. The self-owned drain outlets on the top of the shallow silo can timely drain the water infiltrated through the upper photovoltaic glass silo top, improving the waterproof performance of the shallow silo, especially having an obvious inhibitory effect on water leakage at the lower ring beam. The photovoltaic glass curtain wall can block the sunlight directly shining on the silo wall while generating electricity. The gap between the curtain wall and the silo wall allows for smooth air circulation, further reducing the temperature of the silo wall. The 10 m curtain wall height takes into account both the installation cost and reserves a sufficient height range for the lower operation of the shallow silo and dust dispersion, having good practicability and economy.

[0033] Embodiment 2

[0034] The integrated shallow silo for photovoltaic power generation and waterproof and heat insulation in the embodiment of the present utility model is different from that in Embodiment 1 in that:

[0035] In this embodiment, the curtain wall is an aluminum gusset plate curtain wall. According to the light intensity in the area where the shallow silo is located, the aluminum gusset plate curtain wall is selected to obtain higher economy than installing a photovoltaic glass curtain wall on the premise of ensuring the heat insulation effect.

[0036] Finally, it should be noted that the above embodiments are only the preferred embodiments of the present utility model, and are only used to illustrate the technical solutions of the present utility model rather than to limit them. Any modifications, improvements or other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model shall be included in the protection scope of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
