DETAILED DESCRIPTION

[0023] See also Figure 1-5 The present invention provides a technical solution: a solar panel installation structure on the top of a smart agricultural greenhouse, comprising a support rod 11; a first telescopic mechanism, which is arranged at the upper end of the support rod 11; a mounting mechanism, which is arranged at the upper end of the first telescopic mechanism, and the mounting mechanism is provided with a photovoltaic panel 12; the first telescopic mechanism can drive the mounting mechanism to rise when the temperature inside the greenhouse is lower than a threshold value.

[0024] The photovoltaic panel 12 is installed on the top of the greenhouse for photovoltaic reaction. During this process, the photovoltaic panel 12 will block part of the sunlight to reduce the light intensity of the greenhouse, and further reduce the temperature of the greenhouse under the action of light. When the temperature inside the greenhouse is lower than the threshold, the first telescopic mechanism extends and drives the installation mechanism to rise, so that the photovoltaic panel 12 moves upward, further reducing the shielding effect of the photovoltaic panel 12 on the sunlight, thereby increasing the temperature of the greenhouse under the action of light. Similarly, when the temperature inside the greenhouse is higher than the threshold, the first telescopic mechanism drives the installation mechanism to descend to increase the shielding effect of the photovoltaic panel 12 on the sunlight, so that the temperature of the greenhouse under the action of light decreases.

[0025] The present invention changes the light intensity received by the greenhouse by vertically moving the photovoltaic panel 12, thereby adjusting the temperature inside the greenhouse, effectively reducing the energy consumed to maintain a stable temperature inside the greenhouse, while increasing the effective utilization rate of solar energy.

[0026] As a further solution of the present invention, the first telescopic mechanism includes a first hydraulic rod 21, the upper end of the first hydraulic rod 21 is vertically slidably connected to the second hydraulic rod 22, the mounting mechanism is arranged at the upper end of the second hydraulic rod 22, the lower end of the first hydraulic rod 21 is provided with a buffer mechanism, the buffer mechanism is connected to the upper end of the support rod 11, the buffer mechanism is used to buffer the wind force exerted on the photovoltaic panel 12, the lower end of the first hydraulic rod 21 is provided with a hydraulic mechanism, the hydraulic mechanism is connected to the first hydraulic rod 21, the hydraulic mechanism is used to pump and release hydraulic oil into the first hydraulic rod 21; the first telescopic mechanism also includes an external temperature sensor, the temperature sensor is arranged in the greenhouse, the temperature sensor is used to monitor the greenhouse temperature and control the working state of the hydraulic mechanism according to the greenhouse temperature.

[0027] When the greenhouse temperature is higher than the threshold value, the hydraulic mechanism gradually extracts the hydraulic oil in the first hydraulic rod 21 (the hydraulic mechanism extracts the hydraulic oil in a way of extracting a fixed amount of hydraulic oil at a time, stops for a fixed time after extraction, and then extracts again according to the greenhouse temperature to provide time for the greenhouse temperature to change), so that the second hydraulic rod 22 slides downward relative to the first hydraulic rod 21 under the action of gravity, and further makes the photovoltaic panel 12 arranged on the upper end of the first hydraulic rod 21 close to the top of the greenhouse, so that the photovoltaic panel 12 blocks the sunlight on the top of the greenhouse more, and further reduces the heat generated by light to the greenhouse; when the greenhouse temperature is lower than the threshold value, the hydraulic mechanism gradually injects hydraulic oil into the first hydraulic rod 21, so that the hydraulic oil in the second hydraulic rod 22 increases, and then the first hydraulic rod 21 and the photovoltaic panel 12 arranged on the upper end of the first hydraulic rod 21 are pushed upward by the hydraulic oil, so that the photovoltaic panel 12 moves upward away from the top of the greenhouse, and then the photovoltaic panel 12 blocks the sunlight on the top of the greenhouse less, and further increases the heat generated by light to the greenhouse.

[0028] The present invention changes the height of the photovoltaic panel 12 by pumping out the hydraulic oil in the first hydraulic rod 21 through a hydraulic mechanism, thereby changing the shielding of the photovoltaic panel 12 from the sunlight on the top of the greenhouse, so that the height of the photovoltaic panel 12 changes more and is more in line with the internal temperature of the greenhouse, so that the greenhouse can maintain a suitable temperature under different lighting conditions.

[0029] As a further solution of the present invention, the mounting mechanism includes a mounting frame 31, which is fixedly connected to the upper side wall of the second hydraulic rod 22, a second telescopic mechanism is provided at the upper end of the second hydraulic rod 22, a mounting rod 32 is provided at the upper end of the second telescopic mechanism, the mounting rod 32 is connected to the upper end of the photovoltaic panel 12, and the mounting frame 31 is connected to the lower end of the photovoltaic panel 12.

[0030] As a further solution of the present invention, the second telescopic mechanism includes a third hydraulic rod 41, which is elastically slidably connected to the inner wall of the second hydraulic rod 22, and is fixedly connected to the lower end of the mounting rod 32. The front and rear sides of the upper end of the mounting frame 31 are transversely provided with sliding grooves 42, and sliders 43 are slidably connected in the sliding grooves 42. The two sliders 43 are rotatably connected to the front and rear side walls of the photovoltaic panel 12 respectively, and the upper end of the photovoltaic panel 12 is rotatably connected to the mounting rod 32.

[0031] When hydraulic oil is injected into the first hydraulic rod 21, under the action of the elastic force between the third hydraulic rod 41 and the second hydraulic rod 22, the second hydraulic rod 22 moves vertically upward relative to the first hydraulic rod 21; after the second hydraulic rod 22 moves up to the limit position, the hydraulic oil pushes the third hydraulic rod 41 to overcome the elastic force, so that the third hydraulic rod 41 moves upward relative to the second hydraulic rod 22, and further moves the upper end of the photovoltaic panel 12 vertically upward, so that the photovoltaic panel 12 gradually rotates to a vertical state, thereby reducing the obstruction of light.

[0032] The present invention utilizes the third hydraulic rod 41 to move upward vertically to enable the photovoltaic panel 12 to rotate, and controls the upward movement order of the second hydraulic rod 22 and the third hydraulic rod 41 through the elastic force, so that the photovoltaic panel 12 first moves away from the greenhouse to reduce the light blocking of the greenhouse. When the distance from the greenhouse is not enough to compensate for the heat loss caused by the natural heat dissipation of the greenhouse, the photovoltaic panel 12 will be gradually rotated to a vertical state to further reduce the light blocking of the greenhouse; thus, the utilization rate of light energy is greatly increased.

[0033] As a further solution of the present invention, the buffer mechanism includes two first connecting blocks 51 symmetrically fixedly connected to the side walls of the first hydraulic rod 21 in the front and rear directions, the first connecting blocks 51 are rotatably connected to the inner wall of the support rod 11, the side walls of the first hydraulic rod 21 are fixedly connected to two second connecting blocks 52 symmetrically arranged above the first connecting blocks 51, the second connecting blocks 52 are fixedly connected to elastic telescopic rods 53, the elastic telescopic rods 53 are fixedly connected to the inner wall of the support rod 11, and a feedback mechanism is provided at the lower end of the first hydraulic rod 21, and the feedback mechanism is used to control the contraction of the first telescopic mechanism after the compression amount of the elastic telescopic rod 53 reaches a threshold value.

[0034] When the photovoltaic panel 12 is subjected to wind force, the photovoltaic panel 12 will tend to rotate left and right. At this time, the elastic telescopic rod 53 is used to buffer the rotation trend of the photovoltaic panel 12, thereby further preventing the photovoltaic panel 12 from being damaged when subjected to strong wind.

[0035] As a further solution of the present invention, the hydraulic mechanism includes a mounting plate 61, which is fixedly connected to the inner wall of the support rod 11, and the upper end of the mounting plate 61 is fixedly connected to an oil tank 62, and the upper end of the oil tank 62 is fixedly connected to an oil pump 63, and the oil pump 63 is fixedly connected to the lower end of the first hydraulic rod 21, and the temperature sensor is used to control the operation of the oil pump 63.

[0036] The oil pump 63 completes the up and down movement of the second hydraulic rod 22 by injecting the hydraulic oil in the oil tank 62 into the first hydraulic rod 21 or injecting the hydraulic oil in the first hydraulic rod 21 into the oil tank 62 .

The elastic telescopic rods 53 are all externally connected to a pressure sensor, and the pressure sensor is used to control the on and off of the electrically controlled valve 71.

[0039] When the photovoltaic panel 12 is hit by strong wind and the first hydraulic rod 21 rotates, one of the corresponding elastic telescopic rods 53 will be compressed, and the pressure sensor will further control the electric control valve 71 to open, so that the first hydraulic rod 21 is connected with the oil tank 62, and the hydraulic oil in the first hydraulic rod 21 further flows into the oil tank 62, so that the second hydraulic rod 22 moves downward, thereby reducing the torque on the first hydraulic rod 21 and avoiding equipment damage.
