[0002] As a common facility in modern agricultural production, agricultural greenhouses play a vital role in increasing crop yields, extending the growing season, and optimizing the growing environment. The greenhouse roof structure is a key component in ensuring its normal operation and resistance to natural disasters such as wind and snow.

[0003] Traditional agricultural greenhouse roof support structures typically consist of a frame assembled from materials such as steel pipes and wood, with the shed fabric laid over the frame. While the frame provides effective support for the shed fabric, there are still overhanging areas beneath the shed fabric. These areas are susceptible to deformation when impacted by rain, snow, and hail, leading to accumulation of these areas and potentially damaging the shed fabric.

[0004] When there is too much snow, the accumulated weight will generate greater pressure, increase the burden on the supporting frame, and may even cause the frame to collapse, posing a safety hazard.

[0005] Therefore, a roof support structure of an agricultural greenhouse is proposed to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 3The utility model provides an embodiment: a roof support structure of an agricultural greenhouse, including a support frame 2 for supporting the overall device, the support frame 2 is installed by multiple steel pipes, a shed cloth 1 is installed on the outside of the support frame 2, the shed cloth 1 is a transparent plastic cloth, and a support plate 3 is fixedly connected to the left surface of the support frame 2. The support frame 2 can provide support for the support plate 3, and a buffer component is provided on the upper surface of the support plate 3. The buffer component can effectively reduce the impact of rain, snow and hail on the shed cloth 1. The upper surface of the support plate 3 is provided with a sensing component, which can sense pressure and can reduce the impact of rain, snow and hail on the shed cloth 1.

[0035] Reference Figure 2 、 Figure 3 、 Figure 5 The sensing component includes a hollow tube 42, which is sealed. The cavity inside the hollow tube 42 is divided into two parts, the upper part has a short diameter, and the lower part has a long diameter. A pressure sensor 43 is provided on the inner wall of the bottom end of the hollow tube 42. The pressure sensor 43 is a prior art and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The pressure sensor 43 can sense pressure. A positioning block 44 is slidably connected to the inner wall of the hollow tube 42. The positioning block 44 is provided on the inner wall of the hollow tube 42. A protrusion is provided at the right end of the block 44, and a positioning groove that fits with the protrusion is provided at the bottom end of the right inner wall of the hollow tube 42. The positioning block 44 can only move longitudinally along the positioning groove. The positioning block 44 is elastically connected to a sealing gasket 46 through a compression spring 45. The sealing gasket 46 is located at the part with a longer diameter. A through hole 401 is provided on the upper surface of the sealing gasket 46. The aperture of the through hole 401 is small, which can limit the flow rate of air. When the sealing gasket 46 moves, it will squeeze the air inside the hollow tube 42, and the air will pass through the through hole 401. The upper surface of the sealing gasket 46 is fixedly connected to a sliding rod 47. The sealing gasket 46 and the sliding rod 47 will move synchronously. The upper surface of the sliding rod 47 is fixedly connected to the support plate 41.

[0036] Reference Figure 1 - Figure 3 The buffer assembly includes a hinge seat 51, the bottom end of the hinge seat 51 is hinged with a connecting rod 52, the upper surface of the support plate 3 is fixedly connected with a fixing block 55, and the fixing block 55 is elastically connected to the connecting block 53 through a connecting spring 54.

[0037] Reference Figure 3 - Figure 5The lower surface of the hollow tube 42 is fixedly connected to the upper surface of the support plate 3, and the support plate 3 provides support for the hollow tube 42. The lower surface of the positioning block 44 contacts the upper surface of the pressure sensor 43. The pressure exerted on the positioning block 44 can be transmitted to the pressure sensor 43. The pressure sensor 43 is connected to the external alarm system through a wireless network. When the pressure sensor 43 is subjected to a large pressure, the alarm system will sound an alarm. One end of the compression spring 45 is fixedly connected to the upper surface of the positioning block 44, and the other end of the compression spring 45 is fixedly connected to the lower surface of the sealing gasket 46. The sealing gasket 46 piston is connected to the inner wall of the hollow tube 42. When the sealing gasket 46 moves downward, it squeezes the compression spring 45 to generate a reaction force. The sliding rod 47 passes through and is slidably connected to the upper surface of the hollow tube 42. The upper surface of the support plate 41 contacts the inner wall of the shed cloth 1, which can provide support for the shed cloth 1.

[0038] Reference Figure 1 - Figure 3 The hinge 51 that moves downward will squeeze the connecting rod 52 and make it swing. One end of the connecting spring 54 is fixedly connected to the right surface of the connecting block 53, and the other end of the connecting spring 54 is fixedly connected to the left surface of the fixed block 55. When the connecting rod 52 swings, it will push the connecting block 53 to move left and stretch the connecting spring 54 to produce a reaction force. The hinge seat 51 is located in the center position of the lower surface of the support plate 41. The connecting rod 52, connecting block 53, connecting spring 54 and fixing block 55 are provided with two groups. The two groups of connecting rods 52, connecting block 53, connecting spring 54 and fixing block 55 are symmetrically distributed left and right about the center line of the hinge seat 51, which can disperse the longitudinal impact in the left and right directions, playing the role of force distribution.

[0039] Working principle: When the device is used, after rain, snow or hail falls on the awning cloth 1, the impact force will be transmitted to the support plate 41, and the support plate 41 will move downward a short distance. During the downward movement of the support plate 41, the slide rod 47 and the hinge seat 51 will be driven downward.

[0040] The downward-moving slide bar 47 will drive the sealing gasket 46 to move downward, and the downward-moving sealing gasket 46 will squeeze the air inside the hollow tube 42, and the air will pass through the through hole 401. Since the aperture of the through hole 401 is small, the flow rate of the air will be limited, so it can achieve a damping effect and have a buffering effect. In addition, the downward-moving sealing gasket 46 will also squeeze the compression spring 45 to generate a reaction force, and the reaction force of the compression spring 45 can also reduce part of the impact force.

[0041] The hinged seat 51 moving downward will squeeze the connecting rod 52 to make it swing, and the swinging connecting rod 52 will push the connecting blocks 53 on both sides to open. When the connecting blocks 53 move, they will stretch the connecting spring 54 to generate a reaction force. When the connecting blocks 53 on both sides move horizontally, the impact force will be dispersed to achieve the effect of force buffering. After the impact force is released, the reaction force of the connecting spring 54 and the compression spring 45 will drive the hinged seat 51 and the sliding rod 47 to move upward, lifting the support plate 41. The support plate 41 can provide support for the shed cloth 1 to prevent it from deformation. Rain, snow and hail will slide along the curved surface of the shed cloth 1 and are not easy to accumulate.

[0042] When the compression spring 45 is squeezed, the pressure will be transmitted to the pressure sensor 43 through the positioning block 44. When the pressure sensor 43 senses a large pressure, it will transmit a signal to the external alarm system to remind people to evacuate and reduce safety hazards.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
