Description

Technical Field

[0001] The invention belongs to the technical field of greenhouse infrastructure, and relates to a sliding door suitable for a solar greenhouse, in particular to a sliding door with an insect-proof function suitable for a solar greenhouse. Background Art

[0002] With the development of my country's greenhouse industry, the growth of greenhouse crops has increasingly clear requirements for lighting, ventilation, and pest and disease prevention in the greenhouse. Therefore, the requirements for improving greenhouse hardware facilities are becoming more and more stringent.

[0003] In the prior art, conventional greenhouse doors are only used for people to enter and exit. In order to meet the requirements of lighting, ventilation and insect prevention in the greenhouse, the physical method used is mainly to cover the crops with insect-proof nets. However, this method requires a large amount of insect-proof nets, which will increase greenhouse costs and reduce profits.

[0004] In addition, some greenhouses will install door curtain devices at the greenhouse door to block mosquitoes outside the greenhouse, instead of the insect-proof net covering the crops. The installed door curtain is independent of the greenhouse door and has no connection. When both need to be opened at the same time, they need to be controlled separately, which is inconvenient to use. Summary of the invention

[0005] The object of the present invention is to provide a sliding door with an insect-proof function suitable for a sunlight greenhouse, so as to solve the technical problems existing in the prior art that the greenhouse door has a single function and is inconvenient to be combined with an insect-proof net or a door curtain.

[0006] To achieve the above purpose, the specific technical solutions of the present invention are as follows:

[0007] A sliding door with an insect-proof function suitable for a sunlight greenhouse, comprising a sliding door assembly, a sliding mechanism, an insect-proof net, a door net linkage mechanism and a net collection-release mechanism. The sliding door assembly is arranged at the doorway of the greenhouse main frame through the sliding mechanism and has the freedom to slide to the left and right sides of the doorway of the greenhouse main frame;

[0008] The insect-proof net is vertically stored on the greenhouse main frame on one side of the doorway through a net collection-release mechanism, and the door net linkage mechanism includes a linkage part A and a linkage part B, wherein the linkage part A is arranged at one end of the sliding door assembly close to the insect-proof net, and the linkage part B is fixed to the end of the extended end of the insect-proof net, and the linkage part A has the freedom to contact and separate with the linkage part B under the drive of the sliding door assembly, and to drive the linkage part B and the extended end of the insect-proof net to move and extend to the other side of the doorway;

[0009] The net-retracting and -releasing mechanism is arranged at the fixed end of the insect-proof net and is transmission-connected with the linkage B part through the insect-proof net.

[0010] The sliding mechanism includes a sliding guide rail horizontally arranged on the greenhouse main frame and a pulley arranged on the sliding door assembly and cooperating with the sliding guide rail. The sliding guide rail extends from the greenhouse main frame on the left side of the door to the door and the greenhouse main frame on the right side of the door in sequence.

[0011] The plane where the sliding door assembly is located is parallel to the plane where the insect-proof net is located when it is unfolded;

[0012] The linkage A part includes a drag strip A, and the linkage B part includes a drag strip B. The drag strip A and the drag strip B are respectively arranged on two opposite side surfaces of the sliding door assembly and the insect-proof net when they are unfolded. The sum of the thicknesses of the drag strip A and the drag strip B is greater than the distance between the opposite side surfaces of the sliding door assembly and the insect-proof net when they are unfolded. The drag strip A is located between the drag strip B and the retracting and releasing net mechanism.

[0013] The net-collecting and releasing mechanism comprises a reel, a traction line, a reel wheel, a movable pulley and a counterweight, wherein the reel is rotatably arranged on the greenhouse main frame and vertically located on one side of the door, and the fixed end of the insect-proof net is fixed on the reel and is retracted by the reel.

[0014] The take-up wheel is fixed on the upper end of the take-up shaft and is coaxial with the take-up shaft. The movable pulley is rotatably arranged on the greenhouse main frame. One end of the traction line is wound and fixed on the take-up wheel, and the other end is fixed on the counterweight after passing the movable pulley.

[0015] The width of the sliding door assembly is LA, and the width of the sliding guide rail is LB, wherein LB≥3LA, and the lengths of the sliding guide rails on the left and right sides of the doorway are not less than the width of the sliding door assembly.

[0016] The sliding guide rails are respectively arranged at the upper and lower ends of the door, and a plurality of brackets are evenly fixed at the upper and lower ends of the sliding door assembly, and the pulleys are arranged on the brackets in a one-to-one correspondence.

[0017] The drag strip A extends from the top of the sliding door assembly to the bottom of the sliding door assembly, and the drag strip B extends from the top of the insect-proof net to the bottom of the insect-proof net.

[0018] The net-retracting and -releasing mechanism also includes a reel protection cover, which is arranged outside the reel and below the reel wheel. The insect-proof net is rotatably stored in the space between the reel protection cover and the reel, and the reel protection cover is fixed to the greenhouse main frame. A vertical through groove is opened on the side of the reel protection cover close to the door, and the extended end of the insect-proof net extends out of the through groove and is fixedly connected to the linkage B part.

[0019] The gravity of the counterweight is smaller than the friction resistance between the sliding door assembly and the sliding guide rail.

[0020] The beneficial effect of the present invention is that the present invention provides a sliding door with an insect-proof function suitable for a solar greenhouse, and by setting a door net linkage mechanism and a net-retracting and -releasing mechanism, the door opening and closing and the insect-proof net-retracting and -releasing actions are logically associated, thereby realizing an effective combination of the door opening and insect-proof functions. The present invention determines whether the insect-proof net is activated by controlling the horizontal movement direction of the sliding door:

[0021] When the sliding door assembly closes the door, the insect-proof net is stored in the net-retracting and releasing mechanism;

[0022] When the sliding door assembly is pushed to move to the side away from the insect-proof net, the door-net linkage mechanism drives the insect-proof net to open with it. At this time, the greenhouse door is opened and the insect-proof net is activated;

[0023] When the sliding door assembly is pushed to move toward the insect-proof net side, the door-net linkage mechanism is separated, the sliding door is opened alone, and the insect-proof net is not activated.

[0024] It can be seen that the technical solution provided by the present invention can synchronize the movement of the sliding door assembly and the insect-proof net when insect prevention is needed, and the opening of the door and the closing of the insect-proof net are timely and effectively connected, which can effectively reduce the probability of mosquitoes following in. The net collection and release mechanism can automatically be stored in the reel protective cover when the insect-proof net is idle, which prolongs the service life and replacement cycle of the insect-proof net and reduces the cost of insect prevention; in addition, the net collection and release mechanism in the present invention is designed in the way of gravity conversion and torque transmission. In the process of collecting and releasing the net, the rotational torque generated is uniform, the harmful pulling force on the insect-proof net is small, and the pulling force provided is stable and balanced, and the effect is better than that of mechanical springs.

[0025] The technical solution provided by the present invention has a simple structure, low cost, is easy to implement, has a good follow-up insect prevention effect, and is suitable for promotion and application in the field of greenhouse infrastructure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] like Figures 1 to 9 As shown, the present invention provides a sliding door with an insect-proof function suitable for a sunlight greenhouse, which includes a sliding door assembly 2, a sliding mechanism, an insect-proof net 3, a door net linkage mechanism, and a net collection-release mechanism. The sliding door assembly 2 is arranged at the doorway of the greenhouse main frame 1 through the sliding mechanism, and has the freedom to slide on the left and right sides of the doorway of the greenhouse main frame 1, so that the sliding door can be opened in different directions, which is a prerequisite for realizing single door opening and door opening-activation of the insect-proof net 3;

[0038] The insect-proof net 3 is vertically stored on the greenhouse main frame 1 on one side of the door through a net collection-release mechanism. The door net linkage mechanism includes a linkage A part and a linkage B part. The linkage A part is arranged at the end of the sliding door assembly 2 close to one end of the insect-proof net 3, and the linkage B part is fixed to the end of the extended end of the insect-proof net 3. The linkage A part has the freedom to move left and right, contact and separate with the linkage B part under the drive of the sliding door assembly 2, and drive the linkage B part and the extended end of the insect-proof net 3 to move and extend from one end of the doorway where the net collection-release mechanism is fixed to the other side of the doorway;

[0039] The net-retracting and -releasing mechanism is arranged at the fixed end of the insect-proof net 3 and is transmission-connected with the linkage part B through the insect-proof net 3. It can automatically retract and release the insect-proof net 3 under the drive of the sliding door assembly 2 and the linkage parts A and B.

[0040] Specifically, Figure 7 , Figure 8 As shown, the plane where the sliding door assembly 2 is located is parallel to the plane where the insect-proof net 3 is located when it is unfolded; the linkage A part includes a drag bar A7, and the linkage B part includes a drag bar B8. The drag bar A7 and the drag bar B8 are respectively arranged on the two opposite sides of the sliding door assembly 2 and the insect-proof net 3 when they are unfolded. The sum of the thickness of the drag bar A7 and the drag bar B8 is greater than the distance between the opposite sides of the sliding door assembly 2 and the insect-proof net 3 when they are unfolded. At the same time, in order to ensure that the drag bar A7 can smoothly drive the drag bar B8 to open the insect-proof net 3, in this embodiment, the drag bar A7 is arranged between the drag bar B8 and the retractable net mechanism. In order to eliminate the gap between the sliding door assembly 2 and the insect-proof net 3 and prevent mosquitoes from flying into the greenhouse from the gap, the drag bar A7 is arranged to extend from the top of the sliding door assembly 2 to the bottom of the sliding door assembly 2, and the drag bar B8 is arranged to extend from the top of the insect-proof net 3 to the bottom of the insect-proof net 3.

[0041] Further, such as Figures 1 to 4 As shown, the sliding mechanism includes a sliding guide rail horizontally arranged on the greenhouse main frame 1 and a pulley 6 arranged on the sliding door assembly 2 through a bracket 15 and cooperating with the sliding guide rail, wherein, in order for the sliding door assembly 2 to be able to slide smoothly when the sliding door assembly 2 is pushed, the sliding guide rail includes an upper sliding guide rail 4 located at the upper end of the sliding door assembly 2 and a lower sliding guide rail 5 located at the lower end thereof, and a plurality of brackets 15 are evenly fixed on the upper and lower ends of the sliding door assembly 2, respectively, and the pulleys 6 are arranged on the brackets 15 one by one. In order to enable the sliding door assembly 2 to open to the left and to the right, the sliding guide rail in this embodiment extends from the greenhouse main frame 1 on the left side of the doorway to the greenhouse main frame 1 on the right side of the doorway in sequence. Specifically, the width of the sliding door assembly 2 is set to LA, the width of the sliding guide rail is set to LB, and LB≥3LA. The lengths of the sliding guide rails on the left and right sides of the doorway are not less than the width of the sliding door assembly 2.

[0042] Further, such as Figure 1 , Figure 5 , Figure 6 As shown, the net-collecting and releasing mechanism includes a reel 9, a traction line 10, a reel wheel 11, a movable pulley 12 and a counterweight 13. The reel 9 is rotatably arranged on the greenhouse main frame 1 and vertically located on one side of the door. The fixed end of the insect-proof net 3 is fixed on the reel 9 and is stored or unfolded by the rotation of the reel 9.

[0043] The take-up wheel 11 is fixed at the upper end of the take-up shaft 9 and is coaxial with the take-up shaft 9. Driven by the take-up shaft 9, the take-up wheel 11 rotates to roll up the traction line 10 or release the traction line 10. The movable pulley 12 is rotatably arranged on the greenhouse main frame 1. One end of the traction line 10 is wound and fixed on the take-up wheel 11, and the other end is fixed on the counterweight 13 after passing around the movable pulley 12. When the insect-proof net 3 is in a fully stored state, the take-up wheel 11 releases the traction line 10 to the maximum, and the counterweight 13 is located at the bottom; when the insect-proof net 3 is in the process of unfolding, the reel 9 drives the take-up wheel 11 to rotate and roll up the traction line 10, and the counterweight 13 is gradually lifted; when the insect-proof net 3 is extended into place, the reel 9 rolls up the traction line 10 to the maximum, and the counterweight 13 is located at the highest point; when the insect-proof net 3 is in the process of storing, the counterweight 13 falls, driving the take-up wheel 11 and the reel 9 to rotate, the take-up wheel 11 releases the line, and the insect-proof net 3 is gradually rolled onto the reel 9.

[0044] Furthermore, in order to facilitate the control of the position of the drag strip and to enable the counterweight 13 to automatically stop falling and thus stop winding after the insect-proof net 3 is completely wound up, the net-retracting and releasing mechanism in this embodiment also includes a reel protection cover 14, wherein the reel protection cover 14 is arranged outside the winding shaft 9 and below the winding wheel 11, and the insect-proof net 3 is rotatably stored in the space between the reel protection cover 14 and the winding shaft 9, and the reel protection cover 14 is fixed to the greenhouse main frame 1, and a vertical through groove is provided on the side of the reel protection cover 14 close to the door side, and the width of the through groove is smaller than the width of the drag strip B8, and the extended end of the insect-proof net 3 extends out of the through groove and is fixedly connected to the drag strip, and the contact between the drag strip B8 and the through groove prevents the winding shaft 9 from further rotating and winding.

[0045] In addition, in order to ensure that the counterweight 13 of the sliding door assembly 2 can maintain its position and does not automatically fall and reel in after the insect-proof net 3 is started, the gravity of the counterweight 13 is set to be smaller than the friction resistance between the sliding door assembly 2 and the sliding guide rail in this embodiment, so that the insect-proof net 3 can be expanded or retracted to a specified extent as the sliding door moves and no longer automatically returns to a fully retracted state.

[0046] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
