Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-4 The present application provides a technical solution:

[0022] Embodiment one:

[0023] A ventilation and heat dissipation system for a photovoltaic henhouse, comprising a henhouse body 1, a photovoltaic panel wall 2 is further installed on one side of the henhouse body 1, a passage baffle 3 is fixedly installed in the henhouse body 1 on the inner side of the photovoltaic panel wall 2, a ventilation gap adjusting plate 4 is further provided in a telescopic manner on the side of the passage baffle 3 close to the photovoltaic panel wall 2, a sealing enclosure cover 5 is further connected between the ventilation gap adjusting plate 4 and the passage baffle 3, a variable air duct 6 is formed between the ventilation gap adjusting plate 4 and the photovoltaic panel wall 2, a water-proof ventilation opening 7 is formed in the henhouse body 1 above the variable air duct 6 on both sides, and a gas transition channel 8 with a certain spacing is formed between the bottom of the ventilation gap adjusting plate 4 and the bottom plate of the henhouse body 1.

[0024] A airflow bidirectional air duct 9 and a cold air inlet duct 10 are further fixedly installed on the side of the henhouse body 1 away from the photovoltaic panel wall 2, a fan 10 is fixedly installed in the airflow bidirectional air duct 9, and the forward and reverse rotation of the fan 10 controls the flow direction of the gas.

[0025] The ground of the henhouse body 1 is also provided with a drinking trough 11, the drinking trough 11 is communicated with the bottom of the variable air duct 6 through the channel formed on the ground and is provided with a water collecting plate 12, the side of the variable air duct 6 away from the water collecting plate 12 is also provided with a water distributing plate 13, the water distributing plate 13 is communicated with a water storage cabin 14 arranged above the henhouse body 1 through a pipeline, the ventilation gap adjusting plate 4, the photovoltaic panel wall 2, the water distributing plate 13 and the water collecting plate 12 form a water cooling channel, the water storage cabin 14 releases drinking water into the water cooling channel, so that the drinking water is heated by the heat of the photovoltaic panel wall 2, and finally flows into the drinking trough 11 under the action of gravity for the poultry to drink.

[0026] In this embodiment, the chicken house body 1 is used as the main structure, one side of which is provided with a photovoltaic panel wall 2 to convert light energy into electric energy. Since the photovoltaic panel will generate heat during operation, if the heat is not dissipated outward in time, the power generation efficiency will be affected, and even the service life of the photovoltaic panel will be affected. Therefore, in the prior art, there is a heat dissipation chimney formed by the photovoltaic panel and the wall. However, the above-mentioned scheme directly discharges the heat of the photovoltaic panel to the outside, which is not conducive to fully utilizing the heat. Therefore, the present application forms a variable air duct 6 by the ventilation gap adjusting plate 4 and the photovoltaic panel wall 2 on one side of the chicken house body 1, which alternately forms an air inlet and outlet with the airflow bidirectional air duct 9. In hot summer, the heat needs to be dissipated to the outside in time. At this time, the ventilation gap adjusting plate 4 is controlled by the extension mechanism to move away from the side of the photovoltaic panel wall 2, so that the width of the variable air duct 6 is adjusted to the maximum. At this time, affected by the internal heat, a chimney effect is formed in the variable air duct 6, thereby accelerating the flow of gas without power driving. In cooperation with the rotation of the fan 10 in the airflow bidirectional air duct 9, the flow of gas can be further accelerated. While ventilating and dissipating heat, the scheme can also prevent aerosol-shaped bacteria and viruses from staying in the chicken house body 1. The above-mentioned scheme is a commonly used chimney type heat dissipation air duct structure in the prior art. In hot summer, cold air inlet duct 15 can also be used to blow air into the chicken house body 1 to quickly reduce the temperature inside the chicken house, thereby preventing poultry from getting heatstroke in high temperature weather. However, in autumn and winter, the interior of the chicken house needs to be heated properly. At this time, if the ventilation is still carried out in the above-mentioned gas flow manner, the heat will be wasted. Therefore, in such a low temperature environment, the rotation direction of the fan 10 is changed, so that the airflow flows into the chicken house body 1 from the variable air duct 6 and flows out from the airflow bidirectional air duct 9. The beneficial effect brought by this is that the heat on the surface of the photovoltaic panel wall 2 is brought into the chicken house body 1 with the flow of gas, and the heated gas can heat the poultry activity space, thereby improving the utilization of energy. The heat of the photovoltaic panel wall 2 is ingeniously used to heat the chicken house, without the need for additional heating devices. In order to ensure the heat dissipation effect of the surface of the photovoltaic panel and realize the heat exchange between the photovoltaic panel wall 1 and the airflow, the ventilation gap adjusting plate 4 is controlled to move to the side of the photovoltaic panel wall 2, so that the gas can fully contact the surface of the photovoltaic panel. At this time, the space of the variable air duct 6 becomes smaller, and the airflow is slowly conveyed to effectively heat the gas. In addition, in any season, the heat of the photovoltaic panel wall 2 can be used to heat the water drunk by poultry, thereby transferring the heat to the water, so that the poultry can drink the heated water. This can greatly reduce the temperature on the surface of the photovoltaic panel wall 2. The bidirectional flow of the above-mentioned airflow is adjusted by the rotation direction of the fan 10, so that the chicken house body 1 improves the energy utilization efficiency while ventilating and dissipating heat.

[0027] Embodiment two:

[0028] A pump 16 is further installed on the pipeline between the water storage tank 14 and the water distribution plate 13, and the potable water in the water storage tank 14 is pumped to the water distribution plate 13 through the operation of the pump 16. A plurality of distribution holes 17 are evenly arranged at the bottom of the water distribution plate 13, so that the potable water can uniformly absorb the heat at the back of the photovoltaic panel wall 2. The water storage tank 14 is in communication with an external water supply pipeline.

[0029] A plurality of parallel water falling grooves 19 are arranged on one side of the variable air duct 6.

[0030] In this embodiment, the potable water is injected into the water cooling channel through the water distribution plate 13 by the pump 16. The water cooling channel is formed by the ventilation gap adjusting plate 4, the photovoltaic panel wall 2, the water distribution plate 13 and the water collecting plate 12. The ventilation gap adjusting plate 4 and the photovoltaic panel wall 2 also serve as the forming mechanism of the variable air duct 6, thereby simplifying the structure. The water body uniformly flows through the water distribution plate 13 and is arranged in cooperation with the water falling grooves 19 on the photovoltaic panel wall 2, so as to uniformly absorb the heat at the back of the photovoltaic panel wall 2.

[0031] Embodiment three:

[0032] The mechanism for driving the ventilation gap adjusting plate 4 to perform the extension and contraction movement is an electric hydraulic telescopic rod 18. The electric hydraulic telescopic rod 18 is fixedly installed on the channel baffle. The extension and contraction arm of the electric hydraulic telescopic rod 18 is fixedly connected with the ventilation gap adjusting plate 4.

[0033] A temperature sensor is arranged in the variable air duct 6. The electric hydraulic telescopic rod 18 for driving the ventilation gap adjusting plate 4 to perform the extension and contraction movement is controlled by the respective actuator.

[0034] In this embodiment, the mechanism for driving the ventilation gap adjusting plate 4 to perform the extension and contraction movement is an electric hydraulic telescopic rod 18.
