Description

Technical fields:

[0001] This utility model belongs to the field of shade net technology, and specifically refers to a winter adjustable shade net. Background technology:

[0002] Shade netting is a specialized covering material primarily used to block direct sunlight. In agricultural production such as greenhouse vegetables and flowers, shade netting effectively protects against high temperatures and strong sunlight in summer, providing a comfortable growing environment for plants and improving yield and quality. Simultaneously, it also serves as insulation and cold protection in winter.

[0003] In the field of agricultural planting, shade nets are used to protect crops by means of floating cover, small arched shed cover, and large greenhouse cover. The time of use of shade nets is different in winter and summer. In winter, shade nets are generally used to cover and keep warm at night and are uncovered during the day to ensure that crops can have enough sunlight for photosynthesis.

[0004] In summary, the use of shade nets in winter requires staff to repeatedly put them on and take them off, which is very inconvenient and needs improvement. Summary of the Invention:

[0005] The purpose of this invention is to provide a dimmable shade net for winter use, in order to solve the technical problems mentioned in the background section.

[0006] This utility model is implemented as follows:

[0007] A winter adjustable light-reducing shade net includes a shade net body with a plurality of mesh openings, and a winding mechanism. The shade net body includes a fixed part and an elastic part. The winding mechanism is used to wind up the elastic part. The mesh openings include mounting holes in the fixed part and elastic holes in the elastic part. The elastic part is located on opposite sides of the fixed part.

[0008] Preferably, the fixing part is provided with a plurality of light-concentrating elements, the light-concentrating elements are correspondingly arranged with the mounting holes, and the light-concentrating elements cover the corresponding mounting holes.

[0009] Preferably, the fixing part has an annular groove, which is corresponding to the mounting hole and surrounds the outer periphery of the mounting hole, so that the focusing element can be inserted and positioned.

[0010] Preferably, the light-concentrating element is located within the mounting hole.

[0011] Preferably, the light-concentrating element includes a support frame disposed on the fixing part and a tension membrane disposed on the support frame. The tension membrane is transparent, protrudes outward from the fixing part, and covers the mounting hole.

[0012] Preferably, the winding mechanism includes a winding roller rotatably connected to the support and a rotating motor mounted on the support, wherein the winding roller is used to wind up the elastic portion.

[0013] Preferably, the elastic portion is provided with anti-slip portions at intervals, and the anti-slip portions are located inside the elastic portion.

[0014] Preferably, the elastic part is provided with a plurality of mounting rings, and the mounting rings have openings. The bracket is inserted into the mounting ring through the openings. The mounting rings are elastic, and the openings close under the elastic action of the mounting rings after the bracket passes through.

[0015] The outstanding advantages of this utility model compared to the prior art are:

[0016] 1. After installation, this utility model allows the following functions: During the day, the winding mechanism winds up the elastic part, stretching the elastic part located between the fixed part and the winding mechanism, opening the elastic hole to allow light to enter the shade net through the elastic hole, thus increasing the photosynthesis of plants; at night, the winding mechanism unwinds the elastic part, causing the elastic part located between the fixed part and the winding mechanism to contract, thereby contracting the elastic hole and increasing the heat preservation effect. By changing the size of the elastic hole, the amount of light entering the shade net can be adjusted, eliminating the need to repeatedly open and close the shade net, which helps reduce the workload of workers.

[0017] 2. This utility model, by installing a light-concentrating element on the fixed part, is beneficial to increasing plant photosynthesis;

[0018] 3. This utility model uses a support frame and a transparent tension membrane to form a light-concentrating element, which helps to reduce the weight of the light-concentrating element, and thus helps to reduce the weight of the shade net. Attached image description:

[0024] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:

[0025] This application discloses a dimmable shade net for winter use. See also: A dimmable shade net for winter use. Figure 1 It includes a support frame 1, a shade net body 2, and a winding mechanism 3. The support frame 1 can be bent into an arch shape and is used to support the shade net body 2. The shade net body 2 has several mesh holes 4, which are evenly distributed at equal intervals on the shade net body 2. The mesh holes 4 allow light to pass through the shade net body 2 to promote photosynthesis of the plants below the shade net body 2. The mesh holes 4 also help increase air circulation between the inner and outer sides of the shade net body 2.

[0026] See Figure 1 and Figure 2 The shade net body 2 includes a fixed part 21 and an elastic part 22. The elastic part 22 is located on opposite sides of the fixed part 21 and is fixedly connected to the fixed part 21. The elastic part 22 is elastic and can undergo elastic deformation. The bracket 1 supports the elastic part 22 and the fixed part 21. The fixed part 21 is fixedly connected to the bracket 1. Several mounting rings 221 are fixed on the elastic part 22. The mounting rings 221 are inserted into the bracket 1 and are slidably connected to the bracket 1. The elastic part 22 is connected to the bracket 1 through the mounting rings 221. The mounting rings 221 are elastic and are located at the end of the elastic part 22 closer to the bracket 1. An opening 222 is opened at the end of the mounting ring 221 away from the elastic part 22. The bracket 1 is inserted into the mounting ring 221 through the opening 222. After the mounting ring 221 passes through the opening 222, the opening 222 closes under the elastic action of the mounting ring 221.

[0027] During installation, the opening 222 is opened to insert the bracket 1 into the mounting ring 221, limiting the elastic part 22 and facilitating its even distribution on the bracket 1. When it is necessary to remove the elastic part 22 from the bracket 1, the elastic part 22 is moved away from the bracket 1, and the bracket 1 presses against the inner wall of the mounting ring 221, opening the opening 222 and facilitating the removal of the elastic part 22 from the bracket 1. In this embodiment, the fixing part 21 is fixedly connected to the bracket 1 by a binding rope.

[0028] See Figure 1There are several winding mechanisms 3. The position and number of winding mechanisms 3 correspond one-to-one with the position and number of elastic parts 22. When the elastic part 22 is installed on the support frame 51, the winding mechanism 3 is located on the side of the corresponding elastic part 22 away from the fixed part 21, and the end of the elastic part 22 away from the fixed part 21 is wound into the corresponding winding mechanism 3.

[0029] See Figure 1 The winding mechanism 3 includes a winding roller 31 and a rotary motor 32. The winding roller 31 is rotatably connected to the bracket 1, and its rotation axis is parallel to the length direction of the bracket 1. The winding roller 31 rotates to wind or unwind the elastic part 22. The rotary motor 32 is fixed to the bracket 1 and is rotatably connected to the winding roller 31. The mounting ring 221 is located between the fixed part 21 and the winding roller 31. In this embodiment, the rotary motor 32 is a servo motor, which facilitates control of the rotation speed and number of rotations of the winding roller 31.

[0030] See Figure 1 The mesh 4 includes a number of elastic holes 41 and a number of mounting holes 42. The mounting holes 42 are evenly distributed at equal intervals on the fixing part 21, and the elastic holes 41 are evenly distributed at equal intervals on the elastic part 22. The elastic holes 41 will deform as the elastic part 22 deforms.

[0031] The rotating motor 32 drives the take-up roller 31 to take up or unwind the elastic part 22, causing the elastic part 22 located between the take-up roller 31 and the fixed part 21 to stretch or contract, thereby changing the size of the elastic hole 41 and adjusting the shading rate of the shade net.

[0032] In practical use, the fixed part 21 and the elastic part 22 are supported by the bracket 1. The fixed part 21 is located at the top and is fixedly connected to the bracket 1. The bracket 1 is inserted into the mounting ring 221, and the fixed part 21 and the elastic part 22 are covered over the plant by the bracket 1. When it is a winter night, the rotating motor 32 drives the winding roller 31 to unwind. The elastic part 22 located between the winding roller 31 and the fixed part 21 deforms and contracts under its own elasticity, causing the elastic hole 41 to shrink, increasing the thickness of the elastic part 22 above the bracket 1, which helps to increase the heat preservation effect of the shade net on winter nights.

[0033] During winter daytime, the rotating motor 32 drives the take-up roller 31 to rotate and take up the elastic part 22, stretching the elastic part 22 located between the take-up roller 31 and the fixed part 21. This opens the elastic hole 41, allowing light to pass through the shade net and promoting photosynthesis in the plants below. In this embodiment, the fixed part 21 and the elastic part 22 are woven together.

[0034] See Figure 1 and Figure 3The elastic part 22 has several anti-slip parts 223 evenly distributed on the side near the support 1. The anti-slip parts 223 are composed of several anti-slip protrusions 224. The anti-slip protrusions 224 are integrally formed with the elastic part 22. When the elastic part 22 is supported on the support 1, the anti-slip protrusions 224 abut against the support 1 or the greenhouse protective film installed on the support 1, so that the elastic part 22 located between the winding mechanism 3 and the fixing part 21 is not easily stretched under its own weight.

[0035] See Figure 1 and Figure 3 Several light-concentrating elements 5 are fixed on the fixing part 21. The position and number of light-concentrating elements 5 correspond one-to-one with the position and number of mounting holes 42. The light-concentrating element 5 includes a support frame 51 and a tension membrane 52. Both the tension membrane 52 and the support frame 51 are transparent. The support frame 51 supports the tension membrane 52, causing the tension membrane 52 to bulge away from the support 1. The tension membrane 52 is located inside the fixing part 21, which is beneficial to the flatness of the surface of the fixing part 21. The fixing part 21 has a plurality of annular grooves 211, the position and number of which correspond one-to-one with the position and number of mounting holes 42. The annular grooves 211 are arranged around the outer periphery of the corresponding mounting holes 42 and are connected to the corresponding mounting holes 42. One end of the support frame 51 is inserted and fixed into the annular groove 211. The inner walls of the opposite ends of the annular groove 211 are in contact with the opposite ends of the support frame 51 to limit the position of the support frame 51. The tension membrane 52 is fixed to the support frame 51 and covers the corresponding mounting hole 42. The tension membrane 52 is tensioned at the end of the support frame 51 away from the bracket 1. In this embodiment, the light-concentrating element 5 can also be a convex lens.

[0036] By combining the support frame 51 and the tension membrane 52 into a light-concentrating element 5, it is beneficial to reduce the weight of the shade net and increase the amount of light entering the interior of the shade net during the daytime in winter.

[0037] The implementation principle of a winter adjustable shade net in this application embodiment is as follows: by rotating the motor 32 to drive the winding roller 31 to rotate, the winding roller 31 is controlled to wind or unwind the elastic part 22, thereby controlling the size of the elastic hole 41, which makes it easy to adjust the shading rate of the shade net. There is no need to manually uncover the shade net, which helps to reduce the burden on workers.

[0038] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
