Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a photovoltaic heating plate structure for winter concrete curing. Background Technology

[0002] Winter concrete curing refers to a series of curing measures to ensure the normal solidification of concrete, improve its strength, and prevent frost damage in low-temperature environments. In addition to good insulation measures, a complete curing system is also needed when constructing concrete in winter. During low-temperature processes, the hydration of concrete will be greatly weakened, which will slow down the solidification rate and the strength increase. Extremely low ambient temperature, drastic temperature changes, and freeze-thaw cycles can all damage the concrete structure, such as causing adverse effects like thawing expansion and chemical changes caused by ice crystals.

[0003] Currently, flexible monocrystalline silicon photovoltaic panels are usually connected to the template body through a support frame and fixed to the template body with bolts. However, when maintaining and disassembling monocrystalline silicon photovoltaic panels, tools are required to remove the bolts.

[0004] In view of this, the present invention proposes a photovoltaic heating plate structure for winter concrete curing to solve the above-mentioned technical problems. Utility Model Content

Flexible monocrystalline silicon photovoltaic panels can directly convert solar energy into electrical energy. Part of the electricity is supplied to the graphene electric heating film in real time for concrete heating, while the other part is stored in the energy storage battery for backup. This reduces dependence on traditional electricity or fossil fuels. During non-sunlight periods, the energy storage battery provides power, avoiding the high electricity costs associated with relying solely on grid heating. By reducing curing energy consumption from both the energy source and usage perspectives, construction costs are significantly reduced, meeting the requirements of low cost and low energy consumption in green construction.

[0037] The photovoltaic heating structure includes a flexible monocrystalline silicon photovoltaic panel 3 embedded in the template body 1. The bottom of the flexible monocrystalline silicon photovoltaic panel 3 is connected to the top plate of the support frame 201. A graphene electric heating film 301 is attached to the bottom of the inner cavity of the template body 1 by means of a high temperature resistant adhesive. An aluminum alloy heat-conducting plate 302 is attached to the top of the graphene electric heating film 301 by means of a high temperature resistant adhesive.

[0038] The photovoltaic heating structure also includes a U-shaped groove sealing strip 4 fixedly connected to the bottom of the template body 1. A vacuum insulation board 401 is embedded in the inner cavity of the U-shaped groove sealing strip 4, and the outer surface of the vacuum insulation board 401 is tightly attached to the inner wall of the U-shaped groove sealing strip 4.

[0039] The snap-fit ​​structure includes multiple connecting ear plates 5 fixedly connected to the front and rear surfaces of the aluminum alloy heat-conducting plate 302.

[0041] Multiple sensor mounting holes 7 are provided at the bottom of the inner cavity of the template body 1. The sensor mounting holes 7 are used to install concrete curing parameter detection sensors.

[0042] The surface of the knob 208 is provided with anti-slip texture. The anti-slip texture is a concave structure that is spaced apart, and the anti-slip texture is evenly distributed along the circumference of the knob 208.

[0043] The two ends of the return spring 209 are fixedly connected to one end of the friction plate 207 and one end of the knob 208, respectively. The return spring 209 is always in a pre-compressed state to push the friction plate 207 to adhere to the outer surface of the template body 1.

[0044] The template body 1 serves as the foundation of the overall structure. The connecting groove 2 at the bottom of its inner cavity is used to position the support frame 201, ensuring that the support frame 201 stably supports the flexible monocrystalline silicon photovoltaic panel 3. When installing the support frame 201, after embedding it into the connecting groove 2, it needs to be detachably fixed using a fixing pin 205: Insert the fixing pin 205 through the insertion hole 202 on the front and rear surfaces of the template body 1, so that one end of the fixing pin 205 extends into the inner cavity of the support frame 201. Simultaneously, the locking block 206 on the surface of the fixing pin 205 slides into the locking groove 203 along the guide hole 204. Rotate the knob 208 at one end of the fixing pin 205 to engage the locking block 206. 06 engages with the snap-fit ​​groove 203 to complete the initial fixation of the support frame 201; the return spring 209 between the knob 208 and the friction plate 207 is always in a pre-compressed state, which can push the friction plate 207 to fit tightly against the outer surface of the template body 1, and restrict the rotation of the fixing pin 205 through friction, so as to prevent the snap-fit ​​block 206 from coming loose from the snap-fit ​​groove 203, thereby ensuring the stability of the connection between the support frame 201 and the template body 1; in addition, the spaced concave anti-slip texture (evenly distributed along the circumference) on the surface of the knob 208 can increase the grip friction of the hand, making it easy for the operator to rotate and adjust the fixing pin 205;

[0045] The flexible monocrystalline silicon photovoltaic panel 3 embedded in the template body 1 can directly absorb solar energy with a conversion efficiency of ≥22%, and can convert light energy into electrical energy in real time. Part of the generated electrical energy is directly transmitted to the graphene electrothermal film 301, and the other part is stored in the energy storage battery through a series circuit to store electrical energy for non-sunlight periods (night, cloudy days).

[0046] The graphene electric heating film 301, which is attached to the bottom of the inner cavity of the template body 1 with a high-temperature resistant adhesive, is connected in parallel with the circuit of the flexible monocrystalline silicon photovoltaic panel 3. It can convert electrical energy into heat energy with an electrothermal conversion rate of ≥98%, and can quickly generate stable heat. When there is sufficient sunlight, the graphene electric heating film 301 will give priority to using the electrical energy output in real time from the flexible monocrystalline silicon photovoltaic panel 3. When there is insufficient sunlight or no sunlight, it will automatically switch to the energy storage battery to ensure that the heating function is continuous and uninterrupted, and meet the stable heat source required for concrete curing in winter.

[0047] The heat generated by the graphene heating film 301 is first transferred to the aluminum alloy heat-conducting plate 302 on top, which is adhered to it with a high-temperature resistant adhesive. The aluminum alloy heat-conducting plate 302 has a thermal conductivity of 237 W / (m·K), which can quickly and evenly diffuse the heat. Subsequently, the heat is transferred through the aluminum alloy heat-conducting plate 302 to the thermally conductive silicone pad 303. The thermal conductivity of the thermally conductive silicone pad 303 is 1.5 W / (m·K), and it is tightly connected to the aluminum alloy heat-conducting plate 302 via a snap-fit ​​structure. In the snap-fit ​​structure, the front and rear surfaces of the aluminum alloy heat-conducting plate 302... The connecting ear plate 5 supports the rotation of the flip plate 501 via a pin. Flipping the flip plate 501 can drive the snap-fit ​​plate 502 to be embedded into the adapter groove 504 on the front and rear surfaces of the thermal conductive silicone pad 303. At the same time, the triangular snap-fit ​​block 503 on the surface of the snap-fit ​​plate 502 engages with the triangular groove 505 on the inner wall of the adapter groove 504, so that the thermal conductive silicone pad 303 and the aluminum alloy heat-conducting plate 302 are tightly fitted, avoiding heat loss due to gaps; and uniformly transferring heat to the concrete, ensuring that the concrete surface temperature is stable at 15-25℃, with a temperature difference ≤5℃.

[0048] The U-shaped groove sealing strip 4 is fixedly connected to the bottom of the template body 1. The vacuum insulation board 401 embedded in its inner cavity is tightly fitted to the inner wall of the U-shaped groove sealing strip 4. The thermal conductivity of the vacuum insulation board 401 is ≤0.002W / (m·K), which can significantly reduce the transfer of heat from the inside of the template body 1 to the external environment and reduce heat loss.

[0049] When multiple template bodies 1 need to be used together, the convex block 6 on one side of one template body 1 is embedded into the concave groove 601 at the other end of another template body 1 to achieve quick positioning and splicing; the reserved hole 602 inside the convex block 6 and the concave groove 601 is used to pass through the connector (such as bolt) to fix the adjacent template bodies 1 and avoid loosening and gaps at the splicing point.

[0050] To monitor the concrete curing status in real time and ensure curing effectiveness, multiple sensor mounting holes 7 are provided at the bottom of the inner cavity of the formwork body 1 for installing concrete curing parameter detection sensors (such as temperature sensors). The sensors can collect parameters such as surface and internal temperature and humidity of the concrete in real time. The collected parameters can be transmitted to an external PID controller. The controller automatically adjusts the power of the graphene electric heating film 301 according to the preset curing temperature (15-25℃) to ensure that the concrete curing temperature is stable within the target range. At the same time, the parameters can be uploaded to a cloud platform or mobile APP via a wireless transmission module, which is convenient for operators to remotely monitor the curing status. Abnormal situations (such as temperature exceeding the range) can be automatically alarmed, and adjustment measures can be taken in time to ensure the quality of concrete curing. Ultimately, this achieves a 30% increase in the early strength growth rate of concrete and a 100% compliance rate for 28-day compressive strength. Meanwhile, the formwork body 1 can be reused ≥10 times, reducing curing costs.
