Abstract
Description
Technical Field
[0001] This application belongs to the field of insect prevention devices, and specifically relates to a fresh tomato insect prevention greenhouse with an emergency response structure. Technical Background
[0002] An insect prevention net is a net-like fabric made of polyethylene added with chemical auxiliaries such as anti-aging and anti-ultraviolet agents as the main raw material through wire drawing. It has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and odorless, and easy disposal of waste. It can prevent common pests such as flies and mosquitoes. It is convenient to collect and store during normal use. If made of brand-new materials and properly stored, its service life can reach about 3 to 5 years.
[0003] The insect prevention net has less light shading and does not need to be covered during the day and uncovered at night or covered in the front and uncovered in the back. It should be covered throughout the process to prevent pests from having the opportunity to invade and achieve a satisfactory insect prevention effect.
[0004] When cultivating with a small arch shed covering, the arch shed should be higher than the crops to avoid the vegetable leaves sticking to the insect prevention net, preventing pests such as Phyllotreta striolata outside the net from feeding on the vegetable leaves and laying eggs on the vegetable leaves.
[0005] The second batch of tomatoes planted each year is generally in July and August. In the northwest region, there are strong winds in July and August. The existing insect prevention nets cannot provide good wind protection on windy days.
[0006] In the prior art, there is a utility model patent with the application number CN220402533 and the patent name of a windproof vegetable planting greenhouse with an automatically liftable roof. It provides a windproof vegetable planting greenhouse with an automatically liftable roof, including columns, top beams, a liftable roof assembly, a lift drive mechanism, and a film rolling device. By setting a ventilation channel between single planting sheds, it has good ventilation function, is beneficial to vegetable planting, improves the stability of the greenhouse, and can withstand extreme typhoon weather. The liftable roof assembly can be lowered to the ground, leaving only the frame of the columns and top beams, without a wind-catching surface, ensuring that the greenhouse has good wind protection performance when a typhoon comes. However, there are still the following problems:
[0007] Although through the lift drive mechanism of the liftable roof assembly, the windward area can be reduced in sandstorm or hurricane weather, enabling the greenhouse to have good wind protection performance in such extreme weather. However, the lifting of the existing greenhouse requires manual operation by an operator, which not only increases the equipment cost but also the response speed to strong winds depends on the reaction speed of the operator, and it is impossible to respond in time to reduce the windward area. Moreover, its top beam cannot be lifted, and a too-high top beam will still cause the top of the overall structure to be affected by the wind, resulting in poor wind protection response performance of the prior art. Even in extreme hurricanes or sandstorms, the greenhouse may be blown over. Summary of the Invention
[0008] The object of the present application is to address the problem in the prior art that the top beam cannot be lifted, and even if the top beam is too high, the top of the overall structure will still be affected by the wind, resulting in poor wind resistance of the insect-proof net in the prior art.
[0009] To achieve the above object, the present application provides the following technical solutions:
[0010] An anti-insect greenhouse for fresh tomatoes with an emergency response structure, comprising an emergency response wind-resistant frame and a high-elastic insect-proof film net. The high-elastic insect-proof film net is sleeved on the emergency response wind-resistant frame. The emergency response wind-resistant frame includes a central support, a plurality of side supports, and a plurality of wind-receiving telescopic supports.
[0011] The central support includes a central fixing rod, a telescopic rod, and a load-bearing critical support rod. The upper end of the central fixing rod is provided with a first telescopic hole, and the lower end of the telescopic rod is slidably arranged in the first telescopic hole. The load-bearing critical support rod is supported between the central fixing rod and the telescopic rod, and the load-bearing critical support rod breaks under a predetermined pressure.
[0012] A plurality of the side supports are arranged circumferentially and equidistantly around the central support.
[0013] A plurality of the wind-receiving telescopic supports are hinged between the upper ends of the side supports and the upper ends of the plurality of central supports.
[0014] Preferably, the load-bearing critical support rod includes a first rod portion and a second rod portion. One end of the first rod portion is arranged on the central fixing rod, and one end of the second rod portion is arranged on the telescopic rod. The first rod portion and the second rod portion are connected at a first angle, the first angle is less than 180°, and the corner tip of the fold angle between the first rod portion and the second rod portion is away from the telescopic rod.
[0015] Preferably, a clamping block is arranged at the upper end of the central fixing rod, and a clamping member corresponding to the clamping block is arranged on the telescopic rod. The clamping member and the clamping block are in locking cooperation.
[0016] Preferably, a first fixing plate is arranged at the lower end of the central fixing rod, and at least one first fixing hole is opened on the first fixing plate.
[0017] Preferably, a second fixing plate is arranged at the lower end of the side support, and at least one second fixing hole is opened on the second fixing plate.
[0018] Preferably, a plurality of hinged branches are arranged perpendicular to the telescopic rod at the upper end of the telescopic rod.
[0019] Preferably, the wind-receiving telescopic bracket includes a first telescopic part and a second telescopic part. One end of the first telescopic part is telescopically engaged with one end of the second telescopic part. The other end of the first telescopic part is hinged to the articulated branch, and the other end of the second telescopic part is hinged to the upper end of the side bracket.
[0020] Preferably, the high-elastic insect-proof net includes an insect-proof net surface and a light-transmitting shed surface that are butt-jointed with each other. The insect-proof net surface circumferentially surrounds the outside of the side bracket, and the light-transmitting shed surface covers the upper sides of the central fixing rod and several of the wind-receiving telescopic brackets.
[0021] Preferably, the area of the light-transmitting shed surface corresponding to the central fixing rod is fixedly connected.
[0022] Preferably, an entrance and exit is provided on the insect-proof net surface, and an opening and closing piece is detachably arranged at the entrance.
[0023] Beneficial effects: In normal weather without strong winds, the telescopic rod is located at a predetermined position to ensure the height space required for growing tomatoes inside the present application. When the wind force reaches a certain intensity, when the wind-receiving surface (i.e., the insect-proof net covering the upper sides of the central fixing rod and several of the wind-receiving telescopic brackets) is subjected to a horizontal or nearly horizontal wind force reaching a certain intensity, the load-bearing critical strut of the present application breaks, and the top drops, reducing the wind-receiving area of the wind-receiving inclined surface, or even completely flattening and disappearing, thereby weakening the wind force when the present application is affected by the wind. Thus, it has good wind resistance. The wind-receiving telescopic bracket contracts as the telescopic rod moves downward. The downward movement of the telescopic rod causes the top of the wind-receiving surface to move downward, resulting in the upper and lower side lengths of the wind-receiving surface remaining unchanged while the height decreases, and the area of the wind-receiving surface becomes smaller, thereby greatly weakening the wind force when the present application is affected by the wind, enabling it to resist strong winds and preventing the insect-proof net from being blown away by strong winds on windy days.

Detailed implementation manners
[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will further describe the technical solutions of the present application with reference to the drawings of the embodiments of the present application. The present application is not limited to the following specific implementation manners.
[0035] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the present application, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc. indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of the present patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.
[0036] In a specific implementation manner of the present application, as Figures 1 to 9 shown, there is a fresh food tomato insect-proof greenhouse with an emergency response structure, including an emergency response wind-resistant frame 100 and a highly elastic insect-proof membrane net 200. The highly elastic insect-proof membrane net 200 is sleeved on the emergency response wind-resistant frame 100. The emergency response wind-resistant frame 100 includes a central bracket 110, a plurality of side brackets 120 and a plurality of wind-receiving telescopic brackets 130;
[0037] The central support 110 includes a central fixing rod 111, a telescopic rod 112 and a load-bearing critical support rod 113. A first telescopic hole 114 is formed at the upper end of the central fixing rod 111. The lower end of the telescopic rod 112 is slidably disposed in the first telescopic hole 114. The load-bearing critical support rod 113 is supported between the central fixing rod 111 and the telescopic rod 112, and the load-bearing critical support rod 113 breaks under a predetermined pressure. The load-bearing critical support rod 113 can be a straight thin rod clamped between the central fixing rod 111 and the telescopic rod 112. When the windward inclined plane (the windward inclined plane is the insect-proof net covering the upper sides of the central fixing rod 111 and several of the windward telescopic supports 130) is affected by a strong wind of a certain intensity, so that the pressure transmitted to the load-bearing critical support rod 113 is greater than the compressive strength limit of the load-bearing critical support rod 113, that is, greater than the predetermined pressure, the load-bearing critical support rod 113 can break, causing the telescopic rod 112 to displace downward along the inside of the first telescopic hole 114, reducing the height of the entire greenhouse;
[0038] A plurality of the side supports 120 are arranged at equal intervals in the circumferential direction around the central support 110;
[0039] A plurality of the windward telescopic supports 130 are hinged between the upper ends of the side supports 120 and the upper ends of a plurality of the central supports 110.
[0040] In a specific implementation process, after planting tomatoes, the central fixing rod 111 is inserted into the ground and fixed in the exact middle of the tomato planting area. The telescopic rod 112 is placed into the first telescopic hole 114. Then, the lower end of the load-bearing critical support rod 113 is supported on the periphery of the first telescopic hole 114, and the lower end of the telescopic rod 112 is pressed on the upper end of the load-bearing critical support rod 113. The supporting effect of the load-bearing critical support rod 113 makes the hinge point at the upper end of the telescopic rod 112 located at a predetermined height. Then, one end of the windward telescopic support 130 is hinged to the upper end of the telescopic rod 112. A plurality of the side supports 120 are arranged at equal intervals in the circumferential direction around the central support 110 on the outside of the tomato planting area, and the side supports 120 are inserted into the ground. The other end of the windward telescopic support 130 is hinged to the upper end of the side support 120. Finally, the high-elastic insect-proof film net 200 is surrounded outside the side supports 120 and covers the upper sides of the central fixing rod 111 and a plurality of the windward telescopic supports 130;
[0041] When the wind blows in the area where the tomato planting area is located, the insect-proof net covering the upper side of several of the wind-receiving telescopic brackets 130 is affected by the wind and becomes a wind-receiving inclined plane. When the wind-receiving inclined plane (i.e., the insect-proof net covering the upper side of the central fixing rod 111 and several of the wind-receiving telescopic brackets 130) is affected by horizontal or nearly horizontal wind force, an obliquely downward component force perpendicular to the wind-receiving inclined plane will be generated. This component force will be transmitted to the telescopic rod 112 through the hinge point. Since the degree of freedom of the telescopic rod 112 is restricted by the first telescopic hole 114, the telescopic rod 112 will be subjected to a downward pressure when the wind-receiving surface is affected by the above-mentioned component force. Thus, when the wind-receiving surface is affected by horizontal or nearly horizontal wind force, the telescopic rod 112 squeezes the critical rod downward along the direction of the first telescopic hole 114, and the magnitude of the squeezing force is proportional to the magnitude of the wind force received. When the wind force becomes so large that the squeezing force reaches the limit of the squeezing force that the load-bearing critical support rod 113 can withstand, the load-bearing critical support rod 113 breaks, and the supporting effect on the telescopic rod 112 disappears. The telescopic rod 112 displaces downward along the direction of the first telescopic hole 114. When the length of the first telescopic hole 114 is not less than the top height difference of this application (the top height difference is the height difference between the top of the telescopic rod 112 and the top of the side bracket 120 when the telescopic rod 112 is in the predetermined position), the top of the telescopic rod 112 of this application will be completely lowered to the same height as the top of the side bracket 120, and the entire wind-receiving inclined plane disappears. Only the highly elastic insect-proof membrane net 200 between the side brackets 120 is affected by the wind. Thus, in normal weather without strong wind, the telescopic rod 112 is in the predetermined position, ensuring the height space required for growing tomatoes inside this application. And when the wind force reaches a certain intensity, the load-bearing critical support rod 113 of this application breaks, and the top is lowered, reducing the wind-receiving area of the wind-receiving inclined plane, or even completely flattening and disappearing. Thus, the wind force when this application is affected by the wind is weakened, so it has good wind resistance. The wind-receiving telescopic bracket 130 shrinks as the telescopic rod 112 displaces downward. The downward displacement of the telescopic rod 112 causes the top of the wind-receiving surface to move downward, resulting in the upper and lower side lengths of the wind-receiving surface remaining unchanged while the height decreases, and the area of the wind-receiving surface becomes smaller. Thus, the wind force when this application is affected by the wind is weakened, so it has good wind resistance.
[0042] Beneficial effects: In normal weather without strong winds, the telescopic rod 112 is located at a predetermined position, ensuring the height space required for growing tomatoes inside the present application. When the wind reaches a certain intensity and the windward surface (i.e., the insect-proof net covering the upper side of the central fixed rod 111 and several windward telescopic brackets 130) is subjected to horizontal or nearly horizontal wind of a certain intensity, the load-bearing critical strut 113 of the present application breaks, and the top drops, reducing the windward area of the windward inclined surface, or even completely flattening and disappearing, thereby weakening the wind force on the present application when it is affected by the wind, and thus having good wind resistance. The windward telescopic bracket 130 contracts as the telescopic rod 112 moves downward. When the telescopic rod 112 moves downward, the top of the windward surface moves downward, resulting in the upper and lower side lengths of the windward surface remaining unchanged while the height decreases, and the area of the windward surface becoming smaller, thereby greatly weakening the wind force on the present application when it is affected by the wind, and thus being able to resist strong winds and preventing the insect-proof net from being blown away by strong winds on windy days.
[0043] In the above implementation process, if the load-bearing critical strut 113 used is vertical, when the load-bearing critical strut 113 breaks, the remaining part of the load-bearing critical strut 113 after breaking may lift the telescopic rod 112 from the central fixed rod 111, resulting in the height reduction of the telescopic rod 112 not reaching the preset wind resistance height, thus causing the greenhouse to be blown away by strong winds. In a possible embodiment, as Figure 7 shown, the load-bearing critical strut 113 includes a first rod portion 1131 and a second rod portion 1132. One end of the first rod portion 1131 is arranged on the central fixed rod 111, one end of the second rod portion 1132 is arranged on the telescopic rod 112, and the first rod portion 1131 and the second rod portion 1132 are connected at a first angle, and the first angle is less than 180°, that is, the first rod portion 1131 and the second rod portion 1132 form an acute angle or an obtuse angle. The corner tip of the fold angle of the first rod portion 1131 and the second rod portion 1132 is away from the telescopic rod 112, and the tip of the acute angle or obtuse angle does not face the telescopic rod 112. The first rod portion 1131 and the second rod portion 1132 integrally formed at the first angle will burst in a direction away from the telescopic rod 112 when breaking, thereby preventing the remaining parts of the load-bearing critical strut 113 with incomplete breakage from abutting against each other, avoiding the height reduction of the telescopic rod 112 not reaching the preset wind resistance height due to the residue of the load-bearing critical strut 113, and preventing the greenhouse roof from being blown away due to this.
[0044] In the above implementation process, sometimes if the wind force is extremely strong or the angle of the wind force is appropriate, the top of the greenhouse that is contracted by the telescopic rod 112 may be blown up by the strong wind, causing the telescopic rod 112 to move upward, and the greenhouse cannot maintain the wind-resistant height, resulting in the greenhouse being finally blown away. In a possible embodiment, a clamping block 1111 is provided at the upper end of the central fixing rod 111, and a clamping member 1121 corresponding to the clamping block 1111 is provided on the telescopic rod 112. The clamping member 1121 is in locking cooperation with the clamping block 1111. When the load-bearing critical support rod 113 breaks, the telescopic rod 112 moves downward along the extending direction of the first telescopic hole 114. During this process, the clamping member 1121 moves downward together with the telescopic rod 112. When reaching the wind-resistant height, the clamping member 1121 is aligned and clamped with the clamping block 1111, realizing the locking cooperation between the telescopic rod 112 and the central fixing rod 111, avoiding the situation that the greenhouse cannot maintain the wind-resistant height after contraction and avoiding the top of the greenhouse being finally blown away due to the upward displacement of the telescopic rod 112.
[0045] In the above implementation process, fixing the central fixing rod 111 by inserting it into the ground is a time-consuming and laborious fixing method. In a possible embodiment, a first fixing plate 115 is provided at the lower end of the central fixing rod 111, and at least one first fixing hole 116 is provided on the first fixing plate 115. When fixing the central fixing rod 111, only need to place the central fixing rod 111 at the corresponding position to be fixed, and then insert a nail or a fixing plug through the first fixing hole 116 into the ground to well fix the central fixing rod 111.
[0046] In the above implementation process, fixing the side bracket 120 by inserting it into the ground is a time-consuming and laborious fixing method. In a possible embodiment, a second fixing plate 121 is provided at the lower end of the side bracket 120, and at least one second fixing hole 122 is provided on the second fixing plate 121. When fixing the side bracket 120, only need to place the side bracket 120 at the corresponding position to be fixed, and then insert a nail or a fixing plug through the second fixing hole into the ground to well fix the side bracket 120.
[0047] In the above implementation process, the wind-receiving telescopic bracket 130 is directly hinged between the upper ends of the side brackets 120 and the upper ends of a plurality of central brackets 110. When the number of wind-receiving telescopic brackets 130 is too large, if the upper end of the telescopic rod 112 is too thin, it cannot connect all the wind-receiving telescopic brackets 130. If the upper end of the telescopic rod 112 is thickened, although it can connect all the wind-receiving telescopic brackets 130, the overly thick upper end of the telescopic rod 112 will consume too much manufacturing material. In a possible embodiment, a plurality of hinge branches 1122 are arranged perpendicular to the telescopic rod 112 at the upper end of the telescopic rod 112. Each wind-receiving telescopic bracket 130 corresponds to a hinge branch 1122 and is hinged on the hinge branch 1122, thus avoiding the above problems.
[0048] Further, the wind-receiving telescopic bracket 130 includes a first telescopic part 131 and a second telescopic part 132. One end of the first telescopic part 131 is telescopically matched with one end of the second telescopic part 132. The other end of the first telescopic part 131 is hinged to the hinge branch 1122, and the other end of the second telescopic part 132 is hinged to the upper end of the side bracket 120. Through the first telescopic part 131 and the second telescopic part 132 with telescopic cooperation, the function that the wind-receiving telescopic bracket 130 in the present application needs to expand and contract with the displacement of the telescopic rod 112 can be well realized.
[0049] Further, the high-elastic insect-proof film net 200 includes an insect-proof net surface 210 and a light-transmitting shed surface 220 that are butted against each other. The insect-proof net surface 210 circumferentially surrounds the outside of the side bracket 120, and the light-transmitting shed surface 220 covers the upper sides of the central fixing rod 111 and a plurality of the wind-receiving telescopic brackets 130.
[0050] In the above implementation process, if the high-elastic insect-proof film net 200 is fixedly connected to the emergency response wind-resistant frame 100 everywhere, when the wind telescopic rod 112 group expands and contracts as the telescopic rod 112 displaces, the light-transmitting shed surface 220 covering the upper sides of the central fixing rod 111 and several wind-receiving telescopic supports 130 will descend from a higher top shape to a lower top shape. If the light-transmitting shed surface 220 is fixedly connected to the central fixing rod 111 and several wind-receiving telescopic supports 130 everywhere, the light-transmitting shed surface 220 near the upper side will be subjected to the pulling force of the fixing points of the adjacent wind-receiving telescopic supports 130 that contract and separate, which is likely to cause the light-transmitting shed surface 220 to be damaged. In a possible embodiment, the area of the light-transmitting shed surface 220 corresponding to the central fixing rod 111 is fixedly connected. When the light-transmitting shed surface 220 near the upper side is subjected to the pulling force of the fixing points of the adjacent wind-receiving telescopic supports 130 that contract and separate, due to the elasticity of the high-elastic insect-proof film net 200, the light-transmitting shed surface 220 near the lower side will be pulled upward for a certain compensation. The process is as follows: when the entire light-transmitting shed surface 220 descends as the telescopic rod 112 displaces, the covering volume of the light-transmitting shed surface 220 becomes smaller, and at the same time its surface area becomes smaller. For the sake of easy understanding, take an extreme example. If the telescopic rod 112 descends to the same height as the side support 120, the area covered by the light-transmitting shed surface 220 is the bottom area of the trapezoidal light-transmitting shed surface 220 as shown normally, which is much smaller than the area of the trapezoidal light-transmitting shed surface 220. There will be excess light-transmitting shed surface 220 moved to the position of the light-transmitting shed surface 220 originally near the upper side, so as to make compensation and avoid excessive force on the light-transmitting shed surface 220 near the upper side and cause damage.
[0051] Furthermore, an entrance / exit 211 is opened on the insect-proof net surface 210, and an opening / closing piece 212 is detachably arranged at the entrance. In one implementation manner, the opening / closing piece 212 is matched with the entrance / exit 211 through a zipper. The existence of the entrance / exit 211 facilitates the use personnel to disinfect and enter and exit to replace the load-bearing critical support rod 113 after a strong wind causes the load-bearing critical support rod 113 to break in the greenhouse.
[0052] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, rather than limiting the implementation manners of the present application. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
