Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic planting greenhouses, in particular to an unmanned photovoltaic planting greenhouse. Background Art

[0002] Although photovoltaic greenhouses have many advantages, they also have disadvantages. On the one hand, unlike photovoltaic power generation, photovoltaic panels are set on the top of the greenhouse, and the height of the greenhouse is generally relatively high, so it is not as easy to clean as traditional photovoltaic panels. Studies have shown that the light transmittance of the photovoltaic panel surface has a great influence on its light energy conversion rate. Therefore, in order to improve the utilization rate of solar energy, it is necessary to clean the photovoltaic panels frequently. In addition, since photovoltaic panels are non-transparent, the existing full-coverage design of photovoltaic greenhouses leads to a very low light rate in the greenhouse. Therefore, photovoltaic greenhouses are not suitable for some sun-loving plants, resulting in poor promotion effects. The main function of the greenhouse itself is to better cultivate plants, and photovoltaic power generation is only a means of reuse. It cannot be put the cart before the horse. In addition, photovoltaic panels are prone to freezing in winter, which greatly increases the weight on the top of the greenhouse, posing a great safety hazard.

[0003] This case is proposed to solve or improve the shortcomings or deficiencies of the prior art. Summary of the invention

[0004] The present invention is achieved by adopting the following technical solutions:

[0005] An unmanned photovoltaic planting greenhouse, comprising a greenhouse, wherein the greenhouse body is a steel frame structure, the side is surrounded by a greenhouse plastic film, and the top of the greenhouse is surrounded by glass;

[0006] It also includes a slide rail arranged on the upper and lower sides of the inclined edge of the top of the greenhouse, a slider is slidably arranged on the slide rail, a load-bearing outer frame is bolted on the slider, a photovoltaic panel is arranged and fixed in the load-bearing outer frame, and a non-shielding window with the width of the load-bearing outer frame is left between two adjacent load-bearing outer frames to allow light to enter the greenhouse;

[0007] A driving unit, one end of which is fixed by an anchor point and the other end is connected to the side of the load-bearing outer frame, the driving unit drives the load-bearing outer frame to move laterally by linear motion, and the moving stroke of the driving unit is consistent with the width of the non-blocking window between the load-bearing outer frames.

[0008] In a preferred embodiment, the driving part is a linear telescopic driving rod, one end of which is fixed to the steel frame structure of the greenhouse and the other end is hinged to the load-bearing outer frame.

[0009] In a preferred embodiment, the linear telescopic drive rod is an electric linear push rod, a pneumatic linear push rod, or a hydraulic linear push rod.

[0010] In a preferred embodiment, the driving unit includes a driving motor, a gear, and a rack, wherein the gear is fixed to the main shaft of the driving motor by a key, and the rack is arranged on the side of the slide rail without affecting the sliding position of the slider, and the driving motor is fixed to the load-bearing outer frame and the gear and rack are meshed, and the movement of the load-bearing outer frame is achieved by rotating the gear pair.

[0011] In a preferred embodiment, the driving unit includes a winch, a pull rope, and a hard connecting rod, wherein a rotating rod is fixedly provided on the steel frame structure on the side of the top of the greenhouse, a rotating wheel is rotatably provided in the middle of the rotating rod, the pull rope is wound up by the winch and the rear end of the pull rope is passed around the rotating wheel and fixed on the load-bearing outer frame, a hard connecting rod is fixedly connected between the load-bearing outer frames, and also includes an elastic pull rope, which is arranged at the other end away from the rotating rod and one end of the elastic pull rope is fixed to the steel structure of the greenhouse and the other end is fixed to the load-bearing outer frame. When the winch is wound up, the load-bearing outer frame is pulled to the right to change the light window. When the winch is unwound, the load-bearing outer frame moves to the left under the action of the elastic pull rope.

[0012] In a preferred embodiment, it also includes a rotating frame fixed on the greenhouse, a hollow roller is connected between the rotating frames, a sponge roller is rotatably provided on the hollow roller, and when the load-bearing outer frame moves laterally, the sponge roller contacts the surface of the photovoltaic panel to wipe off dust.

[0013] In a preferred embodiment, drainage holes are provided at intervals inside the hollow roller, and a water supply hose is provided outside the hollow roller. Water is pressed into the hollow roller by a water pump and soaks the sponge roller through the drainage holes. The wet sponge roller can achieve a better cleaning effect.

[0014] In a preferred embodiment, a heating jacket for heating the water supply hose is further included to heat the water supply hose in winter to achieve ice melting.

[0015] In a preferred embodiment, the complete drying shrinkage rate of the sponge roller is greater than fifty percent, and after the sponge roller is completely dried and shrunk, its side walls do not contact the photovoltaic panel. When the sponge roller is completely soaked in water, it recovers and expands, and its diameter becomes larger, so that it can contact the photovoltaic panel. In this way, the photovoltaic panel does not need to be dry rubbed against the sponge roller when not cleaning.

[0016] The advantages and positive effects of the present invention are:

[0017] 1. By adopting the interval arrangement technology, the photovoltaic panels can be moved laterally under the action of the guide rail. In this way, under program control, the photovoltaic panels can be moved laterally at specified intervals (such as 5 minutes) to change the shielding position, making the light transmittance in the greenhouse higher and more uniform.

[0018] 2. By wiping the surface of the photovoltaic panel with a wet and expanded sponge roller while the photovoltaic panel is moved left and right, and combining it with water flushing to achieve cleaning, it is not only simple and convenient, but also stable and reliable, with low energy consumption, ensuring stable and efficient power generation of the photovoltaic panel.

[0019] 3. The thin ice that is about to form or has already formed can be squeezed and crushed by the lateral movement of the load-bearing outer frame to prevent the thickness of the ice from increasing. The crushed ice can easily slide down the top slope of the greenhouse. In particularly severe freezing weather, water can be heated or salt can be added to form brine, which can then be efficiently de-iced on the photovoltaic panel through the hollow roller, ensuring the safety of the greenhouse and preventing it from collapsing.
