Description

Technical Field

[0001] The utility model relates to the technical field of distributed photovoltaic panels on expressways, in particular to a water guide device for the roof of a distributed photovoltaic support frame on expressways. Background Art

[0002] In the design and implementation of distributed photovoltaic systems on highways, photovoltaic bracket roofs are usually used to cover highway-related facilities such as parking areas and service areas to provide sustainable energy solutions. However, these photovoltaic systems face an important environmental challenge, namely how to effectively manage and utilize rainwater that falls on photovoltaic panels. Traditional photovoltaic system designs often ignore rainwater management, resulting in rainwater that may flow directly from the surface of photovoltaic panels into the highway pavement, increasing the water burden on the pavement and potentially affecting driving safety and the durability of the pavement structure. In addition, direct scouring of rainwater may also cause trouble for the maintenance and cleaning of photovoltaic panels.

[0003] Effects of Rain on Photovoltaic Systems

[0004] Safety issues: Untreated rainwater can cause waterlogging on roads, increasing the risk of traffic accidents.

[0005] Limitations of existing technologies

[0006] Although some solutions have attempted to direct rainwater to specific areas through simple slope designs, these methods generally lack effective control over the flow rate of rainwater, fail to fully utilize rainwater resources, and are inefficient when dealing with large amounts of rainfall. In addition, these systems often do not take into account the reuse of rainwater, such as for cooling photovoltaic panels, which can further improve the overall energy efficiency and sustainability of the system.

[0007] Therefore, a new type of water guide device for photovoltaic bracket roof is urgently needed to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a water guide device for the roof of a distributed photovoltaic support on a highway to solve the problems raised in the above-mentioned background technology.

[0014] Preferably, the water absorption end of the heat dissipation mechanism is a C-shaped water-absorbing cotton;

[0015] The heat dissipation end of the heat dissipation mechanism includes:

[0016] A plurality of connecting strips are arranged on the absorbent cotton in a linear array;

[0017] The protective compartment is arranged in a linear array on the roof surface of the photovoltaic bracket and wraps the connecting strips.

[0027] Effective water resource management: Through the structure with V-shaped guide grooves and water retaining plates, this device can effectively collect and guide rainwater, prevent rainwater from flowing directly from the roof of the photovoltaic bracket to the highway, and reduce the risk of slippery road surface and water accumulation.

[0028] Enhanced cooling effect: The heat dissipation mechanism in the device can use the stored water for evaporative cooling through the design of water-absorbing cotton and connecting strips.

DETAILED DESCRIPTION

[0036] In order to facilitate the problem to be solved, the embodiment of the utility model provides a water guide device for the ceiling of a distributed photovoltaic support on a highway. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-4This embodiment provides a water guide device for a highway distributed photovoltaic support roof, including a photovoltaic support roof 100, and also includes:

[0038] The guide groove 200 with a V-shaped body is symmetrically arranged on the side of the photovoltaic bracket ceiling 100, and a plurality of water retaining plates 400 are arranged on the body in a linear array. The guide groove 200 is provided with a water storage tank 300 away from the body side, and a water inlet connected to the water storage tank 300 is arranged at the position where the water retaining plate 400 and the guide groove 200 contact each other. When liquid falls into the guide groove 200, it can be guided due to its V-shape, and the water retaining plate 400 will prevent the liquid from continuing to flow, so that it can enter the water storage tank 300 through the water inlet;

[0039] The water absorption end of the heat dissipation mechanism is arranged in the water storage tank 300, and the heat dissipation end is arranged on the photovoltaic bracket ceiling 100. In this way, the water absorption end located in the water storage tank 300 can transfer the liquid to the heat dissipation end after being full of water. When the external temperature is too high, the water in the heat dissipation end will evaporate to achieve a cooling effect.

[0040] The redirection mechanism is arranged at the bottom of the photovoltaic support roof 100 to collect and change the flow direction of the sewage on the surface of the photovoltaic support roof 100, thereby changing the flow direction of the liquid so that it is not discharged directly into the highway.

[0041] Specifically, the water absorption end of the heat dissipation mechanism is a C-shaped water-absorbing cotton 501, which can absorb water and store it. When the temperature drops, the water-absorbing cotton 501 will freeze once it is frozen. Since it is C-shaped, there is space inside when it expands, thereby avoiding excessive expansion and squeezing the water storage tank 300.

[0042] The heat dissipation end of the heat dissipation mechanism includes:

[0043] A number of connecting strips 502 are arranged in a linear array on the absorbent cotton 501, and the protective compartment 503 is arranged in a linear array on the surface of the photovoltaic bracket ceiling 100, and wraps the connecting strips 502. In this way, when the absorbent cotton 501 is full of water, it will be transferred to the connecting strips 502. When the photovoltaic bracket ceiling 100 is subjected to high temperature, its temperature will evaporate the water on the connecting strips 502, thereby achieving cooling, and with the help of the protective compartment 503, sufficient storage space is provided for the connecting strips 502, so that it can absorb more water.

[0044] Specifically, the redirection mechanism includes:

[0045] The connection chamber 601 is arranged at the bottom of the photovoltaic bracket ceiling 100, and the two water inlets on its surface are respectively connected to the two guide grooves 200, so that the guide grooves 200 can guide the external water into the connection chamber 601 to slow down the flow rate with the help of the chamber body.

[0046] The arc plate 602 is arranged at one end of the connecting bin 601, and its highest point is higher than the plane where the connecting bin 601 is located. The water-permeable holes 603 are arranged in a linear array on the arc plate 602 and are connected to the cavity of the arc plate 602. In this way, the liquid flowing down the photovoltaic bracket ceiling 100 will fall onto the arc plate 602, and flow into the inner side of the arc plate 602 with the help of the water-permeable holes 603, and finally merge with the liquid in the connecting bin. Moreover, since the highest point of the arc plate 602 is higher than the plane where the connecting bin 601 is located, it can store more liquid and prevent the liquid on the photovoltaic bracket ceiling 100 from flowing directly along its slope to the highway road surface.

[0047] The guide plate 604 is arranged on the bottom surface of the curved plate 602, and its inclination direction is opposite to the inclination direction of the photovoltaic bracket roof 100 when it is installed. There is a hole at the contact position between the guide plate 604 and the curved plate 602, so that the liquid in the curved plate 602 flows into the guide plate 604 along the hole. Since the photovoltaic bracket roof 100 is inclined toward the highway surface during installation, the guide plate 604 can guide the liquid away from the highway surface to avoid water accumulation on the road surface.

[0048] Specifically, the absorbent cotton 501 can expand after absorbing water, and there is a gap between it and the water storage tank 300 after expansion, so that these gaps leave space for the absorbent cotton 501 to expand after freezing, thereby reducing the damage caused to the water storage tank 300 by its expansion.

[0049] Specifically, a drainage groove 700 is provided at the top of the photovoltaic bracket ceiling 100, and the drainage groove 700 is divided into front and rear ends, the front end of which is trapezoidal, and the rear end is a right triangle, and the inclined surfaces at the two ends are arranged oppositely. With the help of the inclined surfaces at the front and rear ends, the liquid flowing into the drainage groove 700 can be concentrated and input into the guide grooves 200 on both sides thereof.

[0050] Specifically, the water storage tank 300 is connected to the connecting chamber 601, so that excess water in the water storage tank 300 can enter the connecting chamber 601 and then be discharged to the outside.

[0051] When using:

[0052] The photovoltaic panel is installed on the photovoltaic bracket roof 100, and the direction of the photovoltaic bracket roof 100 is adjusted to make it tilted toward the highway section. When it rains, part of the rainwater will fall into the drainage groove 700. Under the action of the inclined surface of the drainage groove 700, the rainwater will be guided to the guide groove 200. The water retaining plate 400 thereon will block part of the rainwater from entering the water storage tank 300 through the water inlet, so that water can be supplied to the absorbent cotton 501. After the absorbent cotton 501 absorbs water, it will be transferred to the connecting strip 502. When the outside temperature is high, the temperature will evaporate the water on the connecting strip 502 to achieve cooling, and the excess water will flow along the guide groove 200 into the connecting bin 601 and the curved plate 602, and finally the water will be guided to be discharged away from the highway with the help of the guide plate 604.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
