Description

Technical Field

[0001] This utility model relates to the field of shade net technology, specifically a flame-retardant shade net. Background Technology

[0002] Shade nets have become a new type of agricultural protective covering material specifically for wind protection and soil covering. In summer, they serve to block sunlight and rain, while in winter and spring, they also have a certain effect on heat preservation and humidity increase. However, existing agricultural shade nets cover a large area on greenhouse roofs. Due to their large area, they are extremely difficult to roll up, and shade nets lack flame retardant properties. When a part of them catches fire, they can easily spread rapidly over a large area, greatly reducing the survival rate of crops or even causing them to die.

[0003] According to a flame-retardant shade net disclosed in the public notice (announcement number: CN220733748U), the above application includes a left support frame, a connecting rod is fixedly connected to the side surface of the left support frame, a right support frame is movably connected to the side surface of the connecting rod, a left sliding groove is provided on the side surface of the left support frame, and a right sliding groove is provided on the side surface of the right support frame.

[0004] However, in actual use, the above-mentioned shade net only has one support plate in the middle. The shade net itself is soft, and when subjected to gravity or rain pressure, the middle span is too large and it is easy to sag or accumulate water locally, which will cause the shade net structure to deform and reduce its service life. In view of this, we propose a flame-retardant shade net. Summary of the Invention

[0005] The purpose of this invention is to provide a flame-retardant shade net to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant shade net, comprising a support frame, a net body disposed at the top of the support frame, and a support assembly disposed at the top of the support frame, the support assembly comprising:

[0007] A slide rail, wherein a box is fixedly connected to the bottom end face of the slide rail, and a rotating shaft is rotatably connected to the inner wall of the box, and a coil spring is sleeved on the side wall of the rotating shaft;

[0008] A fixed frame has a slot on its bottom end face, which is slidably connected to a sliding rod. A hinge rod is rotatably connected to the side wall of the sliding rod, and a support rod is hinged to the top end face of the hinge rod.

[0013] Preferably, a movable frame is slidably connected to the side of the hinge rod away from the fixed frame, and the end of the net body away from the pivot is fixedly connected to the top end face of the movable frame. By rotating the hinge rod, the movable frame is pushed to move away from the fixed frame, thereby causing the net body to unfold and provide shade for the crops below.

[0014] Preferably, the driving gear meshes with the driven gear, the bidirectional screw is rotatably connected to the bottom of the fixed frame, and the drive motor drives the driving gear to rotate, which in turn drives the driven gear and the bidirectional screw to rotate.

[0015] Preferably, the top end face of the slide rail is provided with a sliding groove, and the sliding groove is slidably connected to the slide frame.

[0016] Compared with the prior art, this utility model provides a flame-retardant shade net, which has the following beneficial effects:

[0017] 1. This flame-retardant shade net uses a set of support components and support rods to support the net body.

Detailed Implementation

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a flame-retardant shade net, including a bracket 1, a net body 2 on the top of the bracket 1, and a support component 3 on the top of the bracket 1. The support component 3 includes a slide rail 301, a box 302, a rotating shaft 303, a coil spring 304, a fixing frame 305, a slot 306, a sliding rod 307, a hinge rod 308, a bidirectional screw 309, a screw block 310, a driven gear 311, a drive motor 312, a driving gear 313, and a support rod 314.

[0026] In one embodiment of this utility model, a slide rail 301 is fixedly connected to the top of a bracket 1, and a box 302 is fixedly connected to the bottom end face of the slide rail 301. A rotating shaft 303 is rotatably connected to the inner wall of the box 302. One end of the net body 2 is fixedly connected to the side wall of the rotating shaft 303. A coil spring 304 is sleeved on the side wall of the rotating shaft 303. One end of the coil spring 304 is fixedly connected to the side wall of the rotating shaft 303, and the other end of the coil spring 304 is fixedly connected to the inner wall of the box 302. The coil spring 304 pulls the net body 2 to rewind through its elastic deformation.

[0027] The fixed frame 305 is fixedly connected to the side wall of the box body 302. The bottom end face of the fixed frame 305 has a slot 306, which is slidably connected to the sliding rod 307. The side wall of the sliding rod 307 is rotatably connected to the hinge rod 308. Several sets of hinge rods 308 are provided, and the several sets of hinge rods 308 are hinged together in a scissor shape. The support rod 314 is slidably connected to the side wall of the slide rail 301. The top end face of the hinge rod 308 is hinged to the support rod 314. The side of the hinge rod 308 away from the fixed frame 305 is slidably connected to the movable frame 4. The end of the net body 2 away from the rotating shaft 303 is fixedly connected to the top end face of the movable frame 4. By rotating the hinge rod 308, the movable frame 4 is pushed to move away from the fixed frame 305, thereby causing the net body 2 to unfold and provide shade for the crops below.

[0028] The side wall of the bidirectional screw 309 is threaded with a screw block 310, and the side wall of the bidirectional screw 309 is fixedly connected with a driven gear 311. The bottom end face of the fixed frame 305 is fixedly connected with a drive motor 312, and the output shaft of the drive motor 312 is fixedly connected with a driving gear 313. The driving gear 313 meshes with the driven gear 311, and the bidirectional screw 309 is rotatably connected to the bottom of the fixed frame 305.

[0029] The drive motor 312 drives the active gear 313 to rotate, which in turn drives the driven gear 311 and the bidirectional screw 309 to rotate, causing the two sets of screw blocks 310 and the sliding rod 307 to move towards each other, thereby driving the hinge rod 308 to rotate. The hinge rod 308 pushes the movable frame 4 to move away from the fixed frame 305, thereby causing the net body 2 to unfold and provide shade for the crops below. The support rod 314 slides with the slide rail 301 and supports the net body 2. The multiple sets of support rods 314 are evenly distributed to provide continuous linear support, making the net surface flatter and preventing the shade net from wrinkling or accumulating water due to local suspension, and preventing it from pressing on the crops.

[0030] The drive motor 312 drives the drive gear 313 to rotate in the opposite direction, and the movable frame 4 moves towards the fixed frame 305. The coil spring 304 pulls the net body 2 to retract through its elastic deformation, so that the net body 2 is rolled into the box 302, which isolates the external fire source from direct contact with the net body 2, reduces the exposed area, reduces the possibility and spread speed of combustion, avoids the rapid spread of fire, reduces the probability of fire accidents, and helps protect the crops below and avoid damage to the crops from the fire.

[0031] In addition, the top end face of the slide rail 301 is provided with a sliding groove 5, which is slidably connected to the sliding frame 6. This allows the device to extend or shorten the spacing between the supports 1 within a certain range according to the actual crop planting needs, flexibly adjust the length and coverage of the shading device, adapt to different crop spacing and planting patterns, quickly adapt to terrain changes, and avoid shading blind spots or repeated construction.

[0032] In this invention, during use, the drive motor 312 drives the active gear 313 to rotate, which in turn drives the driven gear 311 and the bidirectional screw 309 to rotate. This causes the two sets of screw blocks 310 and the sliding rod 307 to move towards each other, thereby driving the hinge rod 308 to rotate. The hinge rod 308 pushes the movable frame 4 to move away from the fixed frame 305, thereby causing the net body 2 to unfold and provide shade for the crops below. The support rod 314 slides with the slide rail 301, and the support rod 314 supports the net body 2. The multiple sets of support rods 314 are evenly distributed to provide continuous linear support, making the net surface flatter. The net body 2 is rolled into the box 302, isolating the net body 2 from direct contact with external fire sources, reducing the exposed area, reducing the possibility and spread of fire, preventing the rapid spread of fire, reducing the probability of fire accidents, and protecting the crops below.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
