Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, and in particular to a greenhouse windproof device. Background Technology

[0002] In the field of agricultural production, greenhouses are an important agricultural facility. They are frame-covered structures with excellent heat preservation performance. By attaching heat-insulating plastic film to the frame, a greenhouse space is formed, which prevents the loss of carbon dioxide produced by crop growth and gives the greenhouse a good heat preservation effect. Its stability and wind resistance are directly related to the safe production and harvest of crops.

[0003] Currently, in traditional engineering practices, greenhouses are mainly protected against wind by reinforcing the frame and retracting the plastic film to improve their wind resistance. While these methods can improve overall wind resistance to some extent, they still have significant drawbacks. On the one hand, the existing greenhouse frame and film structure generates a large wind load during strong winds, easily damaging the frame and insulation film, thus affecting the greenhouse's lifespan. On the other hand, some greenhouses choose to retract the plastic film before strong winds arrive to reduce the load on the frame. While this method can protect the greenhouse structure to some extent, it leaves the crops inside completely exposed to the natural environment, causing serious physical damage and ultimately affecting yield and quality.

[0004] Therefore, improving the wind resistance of greenhouses has become a key technical issue that urgently needs to be addressed in the development of facility agriculture. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a windproof device for greenhouses, which solves the shortcomings of existing greenhouses that suffer structural damage or crop exposure due to wind loads during use.

[0006] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a greenhouse windproof device, which includes a greenhouse frame, a weather collector, an Internet of Things (IoT) control circuit, a forward and reverse self-priming impeller pump, a liquid collection bag, and a PVC steel wire hose. The weather collector and the forward and reverse self-priming impeller pump are installed next to the greenhouse frame and connected to it through the IoT control circuit. The forward and reverse self-priming impeller pump is connected to the liquid collection bag inside the greenhouse frame through the PVC steel wire hose. A U-shaped load-bearing hook structure is fixedly installed at a certain interval along the lower inner side of the main longitudinal beam of the greenhouse frame. Adjacent liquid collection bags are connected in parallel through the PVC steel wire hose and are respectively suspended from the U-shaped load-bearing hook structure by hanging ropes.

[0007] Further improvements are made in that: the shed frame includes a main longitudinal beam, a longitudinal beam, a U-shaped load-bearing hook structure, a transverse triangular bracket, an arc-shaped bracket, and a column. The U-shaped load-bearing hook structure is located on the lower inner side of the intersection of the main longitudinal beam and the transverse triangular bracket. The arc-shaped bracket is fixedly connected to the main longitudinal beam, the longitudinal beam, and the transverse triangular bracket. The column is fixedly connected to the lower side of the transverse triangular brackets at both ends and the end of the arc-shaped bracket.

[0008] Further improvements are made in that: the meteorological data collector includes a pole, a wind speed and direction sensor, and a signal line. The pole is set next to the frame of the shed, and the wind speed and direction sensor is set at the top of the pole.

[0009] A further improvement is that the IoT control circuit includes a polarity reversing switch, a power supply circuit, and a sensing signal line. The polarity reversing switch is connected to the wind speed and direction sensor via the signal line.

[0010] Further improvements are made in that: the reversible self-priming impeller pump includes a self-priming impeller pump, a reversible motor, and a positive and negative pressure sensor. The reversible self-priming impeller pump is located on the outside of the shed frame. The reversible motor is connected to the polarity reversal switch through the power circuit in the Internet of Things control circuit. The positive and negative pressure sensor is connected to the polarity reversal switch through the sensing signal line.

[0011] Further improvements are made in that: the liquid collection bag includes a bag body, a hanging rope, a hanging rope hole, and a counterweight liquid injection port. The counterweight liquid injection port of the liquid collection bag inside the shed frame is connected to the self-priming impeller pump through a PVC steel wire hose. Adjacent liquid collection bags are connected in parallel through PVC steel wire hoses and are respectively suspended by hanging ropes passing through the hanging rope hole on the U-shaped load-bearing hook structure.

[0012] A further improvement is that the PVC steel wire hose includes a three-way connector, and adjacent collection bags are connected in parallel through the three-way connector.

[0013] The beneficial effects of this invention are: it can automatically inject and discharge the counterweight liquid in the collection bag according to the set wind speed and direction parameters, and the reverse movement of the counterweight collection bag can counteract the swaying of the greenhouse frame caused by the wind, effectively avoiding structural damage and thus significantly improving the windproof performance of the greenhouse.

These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0022] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a greenhouse windproof device, including a greenhouse frame 1, a meteorological collector 2, an Internet of Things control circuit 3, a forward and reverse self-priming impeller pump 4, a liquid collection bag 5, and a PVC steel wire hose 6. The greenhouse frame 1 includes a main longitudinal beam 11, a longitudinal beam 12, a U-shaped load-bearing hook structure 13, a transverse triangular bracket 14, an arc-shaped bracket 15, and a column 16. The entire frame is made of modified magnesium oxide composite material or galvanized steel with a diameter of 38mm and a wall thickness of 2mm. The span of the greenhouse frame 1 should meet the requirements of structural strength and suitability for agricultural production. The U-shaped load-bearing hook structure 13 is located on the lower inner side of the intersection of the main longitudinal beam 11 and the transverse triangular bracket 14. The arc-shaped bracket 15 is fixedly connected to the main longitudinal beam 11, the longitudinal beam 12, and the transverse triangular bracket 14. The column 16 is fixedly connected to the lower side of the transverse triangular bracket 14 at both ends and the end of the arc-shaped bracket 15.

The pole 21 is set next to the frame 1 of the shed, and the wind speed and direction sensor 22 is set at the top of the pole 21. The weather data logger 2 monitors wind speed and direction data in real time.

[0024] The IoT control circuit 3 includes a polarity reversing switch 31, a power supply circuit 32, and a sensing signal line 33. The polarity reversing switch 31 is connected to the wind speed and direction sensor 22 via the signal line 23. Based on the wind speed and direction data, the polarity reversing switch 31 selects the path of the power supply circuit 32 to realize meteorological data acquisition and automatic control.

[0025] The reversible self-priming impeller pump 4 includes a self-priming impeller pump 41, a reversible motor 42, and a positive and negative pressure sensor 43. The reversible self-priming impeller pump 4 adopts a flow range of 4000-50000L / h and is set on the outside of the frame 1. The reversible motor 42 is connected to the polarity reversal switch 31 through the power circuit 32 in the Internet of Things control circuit 3. The positive and negative pressure sensor 43 is connected to the polarity reversal switch 31 through the sensing signal line 33. The Internet of Things control circuit 3 realizes automatic control of the reversible self-priming impeller pump 4 to inject and discharge counterweight liquid based on the real-time response of the wind speed and direction monitoring data of the meteorological collector 2 and the positive and negative pressure monitoring data of the self-priming impeller pump 41 by the positive and negative pressure sensor 43.

[0026] The liquid collection bag 5 includes a bag body 51, a hanging rope 52, a hanging rope hole 53, and a counterweight liquid injection port 54. The bag body 51 is made of nylon PE inner film bag with a volume of 20-30L and a compressive strength of 0.2-0.4 MPa. The length of the hanging rope 52 is such that the bag body 51 does not touch the ground when it swings. The counterweight liquid injection port 54 of the liquid collection bag 5 inside the shed frame 1 is connected to the self-priming impeller pump 41 through a PVC steel wire hose 6. Adjacent liquid collection bags 5 are connected in parallel through PVC steel wire hoses 6 and are respectively suspended by the hanging rope 52 through the hanging rope hole 53 on the U-shaped load-bearing hook structure 12. When the liquid collection bag 5 is empty, it is curled up and stored under the main longitudinal beam 11. When the counterweight liquid is injected, it hangs down naturally, so that the reverse movement of the liquid collection bag 5 after counterweighting can counteract the swaying of the shed frame 1 caused by the wind.

[0027] Regarding the PVC steel wire hose 6, the PVC steel wire hose 6 includes a tee connector 61, a working pressure range of 0.2-0.4 MPa, and a pipe diameter that is compatible with the self-priming impeller pump 41 and the counterweight liquid injection / discharge interface 54; adjacent liquid collection bags 5 are connected in parallel through the tee connector 61.
