Description

Technical Field

[0001] The invention relates to the technical field of vegetable planting, and in particular to a high-light-transmittance solar greenhouse. Background Art

[0002] Judging from the current development trend of centralized, large-scale and intensive solar greenhouses, they have good economy and excellent thermal insulation. Vegetable greenhouses are a frame-covered structure with excellent thermal insulation performance. Its appearance allows people to eat off-season vegetables. Generally, vegetable greenhouses use bamboo or steel frames, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space, which is conducive to the growth of vegetables and other crops.

[0003] The prior art discloses a patent with announcement number CN107258387A, which includes an outer arch shed, which is composed of a frame and an outer plastic film covering the outer surface of the frame. Both ends of the side of the frame are provided with a number of frame pillars erected at intervals, the top of the frame pillars are provided with longitudinal beams, and the middle area of ​​the longitudinal beams is provided with cross beams corresponding to the frame pillars. One side of the outer arch shed is provided with a door wall, which has the advantages of being able to extend the use time of the arch shed, effectively controlling the humidity in the shed, quick disassembly and assembly, and high structural strength.

[0004] As the existing technologies including the above patents are used, their shortcomings are gradually exposed, mainly in the following aspects: First, the existing arch shed is limited by its structural limitations, so it is set in the north-south direction. This means that in seasons with lower temperatures, the north-south winds blow directly to the two ends of the arch shed, making the temperature at both ends of the arch shed lower, resulting in a large temperature difference inside the arch shed, affecting the consistency of plant growth.

[0005] Second, when constructing an arch shed, it is necessary to set up multiple reinforcing steel wires parallel to the longitudinal direction of the shed body. The two ends of the reinforcing steel wires are fixed on the ground anchors at both ends of the arch shed, and the reinforcing steel wires are pressed on the top of the shed body. This makes the reinforcing steel wires at both ends of the shed body densely packed, affecting the appearance, and the reinforcing steel wires are exposed to the outside, which often trips the operators and creates safety hazards.

[0006] Third, the arch shed is limited by its shed body setting, which is different from the steel frame type of the high-temperature greenhouse, so that the top of the shed body cannot support the operator's operation, which makes it inconvenient for the operator to operate the shading structure and other components on the top of the two ends of the arch shed.

[0007] Fourth, when vegetables are planted, as the plants grow, ropes are needed to lift the vegetables for growth, and a wire structure is needed to support the ropes. This causes the wire structure to affect the rotary tiller's ability to till the soil at both ends of the shed due to the low height of the lateral ends of the shed, thus reducing the soil treatment efficiency.

[0008] Fifth, during the vegetable planting process, operators use large humidifiers to humidify the interior of the greenhouse as a whole, which affects the operators' vision inside the greenhouse and consumes a lot of water.

[0009] Sixth, the existing arch sheds all have the walkway set in the middle position. In order to increase the planting area, the width of the walkway is often narrow. This makes it difficult for operators to pick vegetables and fruits by placing baskets on the walkway, which affects their walking.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0011] In view of the defects in the prior art, the present invention provides a high-light-transmittance solar greenhouse to solve the problems in the traditional arch shed, where the north-south wind blows directly to the two ends of the arch shed, making the temperature at the two ends of the arch shed lower, resulting in a large temperature difference inside the arch shed; and because the heights of the two lateral ends of the arch shed are relatively low, the steel wire structure affects the rotary tillage of the soil at the two lateral ends of the arch shed, thereby reducing the soil treatment efficiency of the arch shed.

[0012] To achieve the above object, the present invention provides the following technical solutions: A high-light-transmittance solar greenhouse comprises a shed body, both ends of which are provided with translucent protective plates, and the area between the translucent protective plates and the outer ends of the shed body forms a shielding area; A steel wire extending laterally is arranged inside the shed body corresponding to each planting ridge, and a high-position positioning structure and a low-position positioning structure are arranged on the inner top surface of the shed body near the lateral end from top to bottom, and one end of the steel wire is detachably connected to the high-position positioning structure or the low-position positioning structure.

[0017] As an optimized solution, the steel wire is provided with a plurality of suspension ropes with adjustable positions along its extending direction.

[0018] As an optimized solution, an active heating cylinder connected to the heat preservation space is provided on the end of the shed body, and the active heating cylinder is connected to a heat source.

[0019] As an optimized solution, the covering structure includes an arc-shaped covering plate connected between the top of the translucent protective plate and the top of the outer end of the shed body.

[0020] As an optimized solution, a connecting frame is fixedly connected between the translucent protective plate and the outer end of the shelf body.

[0021] As an optimized solution, the supporting structure includes a bamboo plywood arranged conformally on the upper surface of the arc-shaped covering plate.

[0022] As an optimized solution, a plurality of top support rods for supporting the lower surface of the arc-shaped cladding plate are arranged on the top of the connecting frame.

[0023] As an optimized solution, a two-way winding thermal insulation quilt is provided at the center of the outer top of the shed body, and both ends of the two-way winding thermal insulation quilt are supported on the upper surface of the bamboo plywood.

[0024] As an optimized solution, the high-position positioning structure and the low-position positioning structure both include a plurality of U-shaped hangers, one end of each hanger is fixedly connected to the inner top surface of the arch shed, a plurality of steel wires are connected to a first fixed rod toward the same end, and both ends of the first fixed rod are clamped on the hangers at the same height.

[0025] As an optimized solution, a plurality of vertically arranged columns are fixedly connected in parallel along the extension direction of the bottom operating walkway, and the upper ends of the columns are supported by the inner top surface of the arch shed.

[0026] As an optimized solution, the other ends of a plurality of steel wires facing the same direction are connected to a second fixing rod, and the second fixing rod is fixed to the column.

[0027] As an optimized solution, a humidification pipe is fixedly connected to the column along its extension direction, and the inlet ends of a plurality of the flexible humidification tubes are connected in parallel to the humidification pipe.

[0028] As an optimized solution, the flexible humidifying tube is fixed to the steel wire via a clamp.

[0029] As an optimized solution, the steel wire and each of the hanging ropes on the flexible humidifying tube are collectively provided with a slip ring, and the upper end of the hanging rope is slidably connected to the slip ring.

[0030] Compared with the prior art, the present invention has the following beneficial effects: By setting a translucent protective plate on one side of the outer end of the shed, the densely packed steel wire structure in the shielding area can be shielded, preventing the densely packed steel wire structure from being directly seen from the outside, making the shed as a whole more concise and beautiful; And by setting up a translucent protective plate, it can effectively prevent operators from being tripped by the wire structure, thus eliminating safety hazards; By using the translucent protective plate, when the north and south winds blow directly to the two ends of the arch shed in the season with low temperature, the translucent protective plate can be used to block the cold wind from blowing directly on the end surface of the arch shed, thereby reducing the impact of the cold wind on the growth of vegetables near the end of the arch shed; A heat preservation space is formed between the translucent protective plate and the outer end of the shed, and the translucent protective plate is translucent so as not to block light. The heat preservation is achieved by using the heat preservation space, thereby reducing the influence of the external temperature on the internal temperature of the shed in winter. An active heating cylinder connected to the heat preservation space is provided at the end of the shed body, and the active heating cylinder is connected to a heat source, so that when in a very bad weather environment, such as heavy snow with north-south winds, the heat preservation space can be heated by the heat source to increase the temperature of the heat preservation space, thereby assisting the heat preservation space and reducing the influence of the external bad weather on the temperature inside the shed body. The snow accumulated on the translucent protective plate can be melted, and the influence of the external temperature on the temperature inside the shed body can be further reduced, and the temperature difference inside the arch shed can be reduced to ensure the consistency of plant growth. By setting up bamboo plywood and supporting the bamboo plywood with the top support rod on the connecting frame, the bamboo plywood can be used to carry the two-way winding insulation quilt on the top of the shed, reducing the influence of the weight of the two-way winding insulation quilt on the main frame of the shed, and the bamboo plywood can be used to support the operator, so that the operator can perform high-altitude operations. Especially in heavy snow, when all the heavy snow is pressed on the top of the shed, the end of the two-way winding thermal insulation quilt moves along the bamboo plywood, so that the bamboo plywood is used to share the weight of the two-way winding thermal insulation quilt, preventing the shed from being collapsed by the heavy snow. One end of the steel wire is fixed to the column by the second fixing rod, and the other end of the steel wire is fixed to the high-position positioning structure or the low-position positioning structure by the first fixing rod, so that in normal use, the first fixing rod is fixed to the low-position positioning structure for use. When the soil in the shed needs to be rotary tilled later, the first fixing rod is fixed to the high-position positioning structure to raise the height of the steel wire, so that the rotary tilling machine can rotary till the soil at the lateral end of the shed, and the rotary tilling machine can avoid it, so as to prevent the rotary tilling machine from breaking the steel wire. By setting a soft humidifying tube on the steel wire, since the steel wire corresponds to the planting ridge of the vegetables, the soft humidifying tube can be accurately set along the vegetable planting direction. By using the humidifying pipeline to distribute the humidifying gas into the soft humidifying tube, the humidifying gas is dropped from above toward the vegetables to humidify the vegetables. The directional laying can overcome the problem of affecting the operator's operating vision inside the shed due to the large humidifier humidifying the whole inside of the shed in the traditional technology. In addition, the directional laying can also reduce the water consumption and reduce the vegetable planting cost. By sliding a slip ring on the steel wire and connecting the hanging rope to the slip ring, the position of the hanging rope can be adjusted according to the distance between adjacent plants, which is convenient for use. A slide rail is arranged above the bottom operating walkway, a pulley is arranged on the slide rail, and the bottom of the pulley is connected with a lifting type load-bearing platform. The lifting type load-bearing platform can be used to carry baskets, equipment, sprayers and other machinery without affecting the normal work of operators on the bottom operating walkway, thereby expanding the scope of use.

[0056] The end of the arch shed and the translucent protective plate 16 are independently provided with entry and exit doors.

[0057] The working principle of this device is: By arranging a translucent protective plate 16 on one side of the outer end of the shed body, the densely packed steel wire structure 22 in the shielding area is shielded, preventing the densely packed steel wire structure 22 from being directly seen from the outside, making the shed body 1 more concise and beautiful as a whole; Furthermore, by providing the translucent protective plate 16, the operator can be effectively prevented from being tripped by the steel wire structure 22, thereby eliminating potential safety hazards. By using the translucent protective plate 16, when the north-south wind blows directly toward the two ends of the arch shed in the season with low temperature, the translucent protective plate 16 can be used to block the cold wind from blowing directly on the end surface of the arch shed, thereby reducing the influence of the cold wind on the growth of vegetables near the end of the arch shed; A heat preservation space 17 is formed between the translucent protective plate 16 and the outer end of the shed body, and the translucent protective plate 16 is translucent so as not to block light. The heat preservation space 17 is used to achieve heat preservation, thereby reducing the influence of the external temperature on the internal temperature of the shed body 1 in a winter environment. An active heating cylinder 23 connected to the heat preservation space 17 is provided at the end of the shed body 1. The active heating cylinder 23 is connected to a heat source, so that when in a very bad weather environment, such as heavy snow with north-south winds, the heat preservation space 17 can be heated by the heat source to achieve the temperature increase of the heat preservation space 17. The high temperature is used to offset the low temperature of the north-south winds and reduce the temperature difference. The heat preservation space 17 can be assisted to reduce the influence of the external bad weather on the temperature inside the shed body, and the snow accumulated on the translucent protective plate 16 can be melted, so as to further reduce the influence of the external temperature on the temperature inside the shed body 1, reduce the temperature difference inside the shed body 1, and ensure the consistency of plant growth. By providing the bamboo plywood 20 and supporting the bamboo plywood 20 with the top support rod 21 on the connecting frame 18, the bamboo plywood 20 can be used to carry the two-way winding thermal insulation quilt 2 on the top of the shed 1, thereby reducing the influence of the weight of the two-way winding thermal insulation quilt 2 on the main frame of the shed 1, and the bamboo plywood 20 can be provided to support the operator, so that the operator can perform high-altitude operations. Especially in heavy snow weather, when all the heavy snow is pressed on the top of the shed, the ends of the two-way winding thermal insulation quilt 2 move along the bamboo plywood 20, so that the bamboo plywood 20 can share the weight of the two-way winding thermal insulation quilt 2, thereby preventing the shed 1 from being collapsed by the heavy snow.

By arranging the soft humidifying tube 9 on the steel wire 8, since the steel wire 8 corresponds to the planting ridge of the vegetables, the soft humidifying tube 9 can be accurately arranged along the vegetable planting direction, and the humidifying gas is distributed into the soft humidifying tube 9 by using the humidifying pipeline, so that the humidifying gas is dropped from above toward the vegetables to humidify the vegetables. The directional laying can overcome the problem of affecting the operator's sight line inside the shed 1 due to the large humidifier humidifying the inside of the shed 1 in the traditional technology, and the directional laying can also reduce the water consumption and reduce the vegetable planting cost; By slidingly setting a slip ring 14 on the steel wire 8, the suspension rope 15 is connected to the slip ring 14, so that the position of the suspension rope 15 can be adjusted according to the distance between adjacent plants, which is convenient for use; By arranging a slide rail 5 above the bottom operating walkway 3, a pulley 6 is arranged on the slide rail 5, and the bottom of the pulley 6 is connected with a lifting type load-bearing platform 7.
