1 , a cable suspension greenhouse is composed of a plurality of cable suspension units 1 , with a horizontal span and a vertical bay. The greenhouse is a four-bay two-span structure.

Referring to Figure 2, which is a structural diagram of a suspension unit 1, the suspension unit 1 includes left and right columns, upper and lower suspension cables 13 and 14 are fixed between the left and right columns 11 and 12, and supporting cables 15 are arranged between the upper and lower suspension cables 13 and 14, so that the supporting cables 15 form a plurality of continuous V-shaped slopes; this design can form two slopes, three slopes or more than four slopes within one span, and referring to Figure 3, which is a schematic diagram of a greenhouse with a minimum structure composed of a suspension unit 1.

Referring to Fig. 4, it is a structural diagram of the second type of suspension cable unit 1. Based on the structural diagram of Fig. 2, the lower suspension cable 14 is connected to the longitudinal beam 2 through a lower tie rod 17. Referring to Fig. 5, it is a structural diagram of the third type of suspension cable unit 1. Based on the structural diagram of Fig. 4, the number of V-shaped slopes in one span is increased from 3 to 4, and the upper suspension cable 13 is connected to the longitudinal beam 2 through an upper tie rod 16. In actual production, the upper tie rod 16 and the lower tie rod 17 may be used or not according to specific construction requirements.

Referring to FIG6 , it is a schematic diagram of a greenhouse with a minimum structure composed of a third type of cable unit 1; the greenhouse is a one-bay one-span structure, and the top and bottom of the V-shaped slope in the longitudinal direction of the greenhouse are connected as a whole by a longitudinal beam 2, the supporting cable 15 is connected to the longitudinal beam 2, and the upper pull rod 16 and the lower pull rod 17 are fixed. Installed on the longitudinal beam 2; the greenhouse is connected as a whole through the common middle column of the suspension cable unit 1 in the transverse direction; and a film 3 is fixedly laid on multiple V-shaped slopes.

In this embodiment, in order to make the greenhouse installation more secure, anchor cables 7 are provided on the columns around the greenhouse to connect with the ground. In order to prevent the longitudinal shaking of the longitudinal beam, a column 9 can be added at the end slope top of the V-shaped slope, and the column 9 is also connected to the ground through the anchor cable 7. In addition, in order to facilitate the installation of the film 3 around the greenhouse, film clamping grooves 8 for fixing the film 3 can be provided on the columns around the greenhouse, and the film clamping grooves 8 are fixed with film clamping springs.

In this embodiment, a tensioning mechanism 4 is provided on the lower suspension cable 14. The tensioning mechanism 4 is a turnbuckle bolt or a wire tensioner. This design can easily adjust the problem of the greenhouse film being too tight or too loose due to thermal expansion and contraction under different temperature conditions.

In this embodiment, the film 3 is fixedly mounted on the longitudinal beam 2. Referring to FIG8 , the film 3 is formed by overlapping two films at the top of the V-shaped slope, and is fixed to the longitudinal beam 2 by screws through the pressing plate 5. In addition, since the installation of the lower pull rod 17 will penetrate the film 3, and the bottom of the V-shaped slope has the function of drainage, in order to prevent water leakage and prevent the film from sinking to form a water pocket, the film 3 adds a layer of reinforcement material at the bottom of the V-shaped slope, and is fixed to the longitudinal beam 2 by screws through the pressing plate 5. The reinforcement material can be waterproof canvas or hard plastic to strengthen the strength of the bottom of the slope.

10 , the film 3 is fixedly mounted on the longitudinal beam 2 through the film clamping groove 8. Of course, according to actual needs, the film 3 can also be mounted on the longitudinal beam 2 through other common mounting methods, such as bundling, clamping or crimping.

In this embodiment, the upper pull rod 16 and the lower pull rod 17 are both retractable bolts. The direction of the folding line of the integral supporting cable 15 can be adjusted by adjusting the retractable bolts.

The upper pull rod 16 is a retractable bolt fixedly mounted on the longitudinal beam 2, and the upper portion of the retractable bolt is fixedly connected to the upper suspension cable 13. Referring to Fig. 7, the lower pull rod 17 is a retractable bolt fixedly mounted on the longitudinal beam 2, and the bottom of the retractable bolt is a hook or a through hole, and the lower suspension cable 14 is connected to the hook or the through hole.

Referring to FIG9 , the longitudinal beam 2 at the bottom of the V-shaped slope is in a groove shape for drainage. This design forms a drainage ditch for rainwater at the bottom of the slope, and the drainage ditch has a certain slope in the longitudinal direction, which depends on the local rainfall and the topography of the construction site. A hook is connected to the bottom of the longitudinal beam 2, and the lower suspension cable 14 is connected to the hook.

In this embodiment, in order to make the greenhouse better lit, it can be arranged in an east-west direction. When the greenhouse is arranged in an east-west direction, the folding direction of the overall supporting cable 15 can be adjusted by adjusting the upper pull rod 16 and the lower pull rod 17. According to the local winter direct sunlight angle, the shape of the greenhouse is adjusted so that the sunlight vertically shines on the sunny slope at noon in winter. Because the shady slope does not receive sunlight, the shady slope can be covered with insulation materials to reduce the heat emitted by the greenhouse without reducing the sunlight heat received by the greenhouse. Therefore, the lighting and heat preservation performance of the greenhouse can be improved. Therefore, this combination has a good effect and can adapt to the climate of different regions by adjusting the shape of the shed. This design effectively reduces the heat dissipation area of the roof while avoiding blocking the sun. In addition, greenhouse equipment such as roller shutters, air vents, and thermal insulation quilts can be installed on the V-shaped slope to expand the scope of application of the greenhouse. An external shading device can be installed on the top of the greenhouse, and an internal shading and internal second-layer film can be installed inside the greenhouse to improve the insulation and sunshade performance of the greenhouse.

When installing this product, first pass the supporting cable 15 through the connecting holes on the longitudinal beam 2 on the ground, then connect the upper tie rod 16 and the lower tie rod 17 to the longitudinal beam 2, then fix the upper tie rod 16 on the upper suspension cable 13, and connect the lower suspension cable 14 to the lower tie rod 17, then first fix the upper suspension cable 13 to the left and right columns 11 and 12, and then fix the lower suspension cable 14 to the left and right columns 11 and 12, and tighten the supporting cable 15 on the longitudinal beam 2 to complete the approximate shape construction, and adjust the length of the upper tie rod 16 and the lower tie rod 17, the fixed position of the upper tie rod 16 on the upper suspension cable 13, and the tension of the lower suspension cable 14 to achieve the desired shed shape. As long as one span is adjusted, the subsequent other parts can be installed according to the size of the first span. After the installation of the entire cable net is completed, install the film 3, insert the film 3 from the top of the greenhouse, use one film 3 for each V-shaped greenhouse surface, unfold the film 3 flat, and fix the film 3 on the longitudinal beam 2 by crimping or bundling.

This design improves the rigid continuous sloped roof of the original glass greenhouse into a continuous sloped roof with a flexible tension structure, reducing the amount of roof support structural materials used; the existing greenhouse uses an arch or truss beam structure as the main load-bearing structure, and this design uses a cable structure as the main load-bearing structure, which has the advantages of large span and material saving. In addition, the structure also adds a roof surface configuration adjustment structure, which can easily adjust the required greenhouse shape and slope by adjusting the length of the upper pull rod 16 and the lower pull rod 17 and the tension of the lower cable 14. This design has the effect of using less material to build a greenhouse with a larger span. The space inside the greenhouse can adapt to large-scale mechanized operations, improve land utilization, and greatly reduce the materials used in the greenhouse, which is conducive to large-scale promotion and can be widely used in agricultural planting and breeding fields.
