Description

Technical Field

[0001] This utility model relates to the field of bird deterrence technology in airports, and in particular to a bird-proof net that is easy to clean. Background Technology

[0002] In the field of aviation safety, bird strikes pose a serious threat to the safe operation of aircraft. To reduce the bird strike rate, airports usually use bird nets as an important preventive measure.

[0003] In practical applications, bird-catching nets are designed with a net length greater than the distance between two poles for more effective bird trapping. Multiple main lines are used to weave the net between the poles, creating a net-like structure. This design makes the net prone to sliding and shifting on the main lines, affecting its bird-catching effect. To solve this problem, a common practice is to manually add secondary lines to one side of each main line, knotting adjacent main and secondary lines at regular intervals to restrict the net's movement. However, this method requires manual addition of secondary lines and knotting in sections. After prolonged use, the knots loosen, reducing the net's restrictive effect and requiring frequent maintenance and re-knotting, further increasing maintenance costs and workload. Furthermore, airport environments are complex, and lightweight objects such as plastic bags and packaging paper are easily blown into the bird-catching net area. When these objects need to be removed, existing bird-catching net structures typically require workers to climb to higher ground and manually remove them, a highly dangerous, difficult, and inefficient process.

[0004] To address the aforementioned issues, a bird-proof net that is easy to clean is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a bird net that is easy to clean. By using this device, the problems of cumbersome net limiting operation and low cleaning efficiency of light objects in the above-mentioned background technology are solved.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a bird-proof net that is easy to clean, comprising two net poles, a net sheet installed between the two net poles, multiple main lines intersecting the net sheet between the two net poles, a support block fixedly connected to the bottom end of each net pole, a base plate provided below the support block, a support seat slidably connected to the top of the base plate, a limiting component for limiting the support seat provided between the support seat and the base plate, the support block being hinged to the support seat, the support block and the support seat being fixedly connected by bolts and nuts, a support component inserted into the side wall of the support seat, the net sheet having the same number of mesh holes in each row, and the mesh size of the rows of mesh holes through which the main lines intersect being smaller than the mesh size of the rows of mesh holes not through which the main lines intersect.

[0007] Preferably, the limiting component includes a limiting block fixed to the side wall of the support base. The bottom of the limiting block is provided with a limiting hole, and the top of the limiting block is provided with a positioning hole communicating with the limiting hole. The diameter of the limiting hole is larger than the diameter of the positioning hole. A displacement groove communicating with the positioning hole is opened on one side of the positioning hole, and a stop hook is provided on one side of the displacement groove. Both sides of the top of the base plate are provided with stop holes corresponding to the position and diameter of the limiting hole. A limiting rod is slidably connected between the stop hole and the limiting hole. A positioning rod is fixedly connected to the top of the limiting rod. A spring is sleeved on the outside of the positioning rod in the limiting hole. The spring is fixedly connected between the limiting rod and the limiting hole. A displacement block is fixedly connected to one side of the positioning rod. The displacement block is slidably connected to the displacement groove. A handle is fixedly connected to one side of the top of the positioning rod.

[0008] Preferably, the support assembly includes a crossbeam inserted into the side wall of the support base, a support leg fixedly connected to the bottom of the crossbeam, a support rod extending upward toward the support base from the top of the crossbeam, and a support ring fixedly connected to the end of the support rod away from the crossbeam.

[0009] Preferably, a reinforcing rod is fixedly connected between the support rod and the crossbeam.

[0010] Preferably, the total width of the mesh in the main wire interlacing mesh row is equal to the width of the mesh sheet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Efficiently limiting the mesh size: By ensuring that each row of mesh has the same number of openings, and that the mesh size of the rows where the main line passes through is smaller than that of the rows where the main line does not pass through, while the total width of the mesh size of the rows where the main line passes through is equal to the width of the mesh, the sliding displacement of the mesh on the main line is effectively limited while forming a net pocket structure. This avoids the tedious operation of manually adding auxiliary lines and tying knots segment by segment, eliminates the problem of limiting failure caused by loose knots, and significantly reduces maintenance costs and workload.

[0012] Convenient cleaning: By pulling the handle in the limiting component, the displacement block is disengaged from the displacement groove and rotated to the stop hook limit, realizing the sliding adjustment of the support base on the base plate, thereby bringing the two support bases closer to each other. Combined with the hinge structure between the net rod and the support base, by loosening the bolts and nuts and rotating the net rod to flatten the net, the staff can conveniently and quickly clean light objects on the net without having to climb to a high place, reducing the difficulty of cleaning work and improving cleaning efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0017] Combination Figures 1-4 A bird net that is easy to clean includes two poles 1, with a net panel 2 installed between the two poles 1. Multiple main wires 3, intersecting the net panel 2, are arranged between the two poles 1. A support block 4 is fixedly connected to the bottom of each pole 1. A base plate 5 is located below the support block 4. A slide rail parallel to the net panel 2 is located on the top of the base plate 5. A support seat 6 is slidably connected in the slide rail. A limiting component 7 for limiting the support seat 6 is provided between the support seat 6 and the base plate 5 to ensure the stability of the support seat 6 during normal use. The support block 4 is hinged to the support seat 6, and the support block 4 and the support seat 6 are fixedly connected by bolts and nuts, allowing the poles 1 to be adjusted according to actual needs. The angle can be adjusted so that the net 2 can be rotated and laid down when cleaning is needed. The two side walls of the support base 6 perpendicular to the net 2 are provided with slots into which the support component 8 can be inserted. The slots can be plugged when not in use. When loosening or tightening the bolts and nuts between the support block 4 and the support base 6, the support component 8 is inserted into the corresponding slot to provide auxiliary support and enhance the stability of the overall structure. The number of mesh holes in each row of the net 2 is the same, and the mesh size of the main line 3 that passes through the mesh row is smaller than the mesh size of the main line 3 that does not pass through the mesh row. This makes the net 2 form a net pocket structure between the two poles, while effectively restricting the sliding displacement of the net 2 on the main line and improving the bird-blocking effect.

[0018] Furthermore, the limiting component 7 includes a limiting block 71 fixed to the side wall of the support base 6. The bottom of the limiting block 71 is provided with a limiting hole 72, and the top of the limiting block 71 is provided with a positioning hole 73 communicating with the limiting hole 72. The diameter of the limiting hole 72 is larger than the diameter of the positioning hole 73. A displacement groove 74 communicating with the positioning hole 73 is opened on one side of the positioning hole 73, and a stop hook 75 is provided on one side of the displacement groove 74. Both sides of the top of the base plate 5 are provided with stop holes 76 corresponding to the position and diameter of the limiting hole 72. The stop holes 76 can be plugged when not in use. A limiting rod 77 is slidably connected between the stop hole 76 and the limiting hole 72, and a positioning rod 78 is fixedly connected to the top of the limiting rod 77. A spring 79 is sleeved on the outside of the positioning rod 78 in the limiting hole. The spring 79 is fixedly connected between the limiting rod 77 and the limiting hole 72. The spring 79 can provide a reset force so that the positioning rod 78 can automatically reset when no external force is applied. A displacement block 710 is fixedly connected to one side of the positioning rod 78. The displacement block 710 is slidably connected to the displacement groove 74. A handle 711 is fixedly connected to one side of the top of the positioning rod 78. Pulling the handle 711 causes the displacement block 710 to slide in the displacement groove 74. The displacement block 710 is moved out of the displacement groove 74 and rotated into the stop hook 75 so that the stop hook 75 limits the displacement block 710. The positioning rod 78 can then disengage from the positioning hole 73, and the support base 6 can slide on the base plate 5.

[0019] Furthermore, the support assembly 8 includes a crossbeam 81 inserted into the side wall of the support base 6. A support leg 82 is fixedly connected to the bottom of the crossbeam 81, and a support rod 83 extending upwards from the top of the crossbeam 81 is provided. A support ring 84 is fixedly connected to the end of the support rod 83 away from the crossbeam 81. When the bolts and nuts between the support block 4 and the support base 6 are loosened or tightened, the crossbeam 81 is inserted into the corresponding slot. The support leg 82 serves as the support for the bottom of the crossbeam 81, while the support rod 83 and the support ring 84 jointly support the net rod 1, which can provide auxiliary support for the net 2 and the net rod 1, making it easy to loosen or tighten the bolts and nuts between the support block 4 and the support base 6.

[0020] Furthermore, a reinforcing rod 85 is fixedly connected between the support rod 83 and the crossbeam 81, which enhances the overall strength and rigidity of the support assembly 8 through the principle of the stable structure of a triangle.

[0021] Furthermore, the total width of the mesh in the main line 3 is equal to the width of the mesh 2, so that the mesh 2 is precisely limited in the area where the main line 3 intersects. For example, when the width of the mesh 2 is a certain value, by reasonably setting the size and number of individual meshes in the main line 3 intersects the mesh, the total length of the mesh 2 is consistent with the width of the mesh 2, thereby restricting the lateral sliding of the mesh 2 on the main line when the mesh 2 forms a net pocket structure.

[0022] Working principle: In daily use, mesh panel 2 is installed between two poles 1, with multiple main lines 3 interspersed in mesh panel 2. The number of mesh holes in each row of mesh panel 2 is the same. The mesh width of the row of mesh holes through which the main lines 3 intersect is smaller than the mesh width of the row of mesh holes without intersect. For example, if the width of mesh panel 2 is 10 meters, the width of a single mesh hole in the row of mesh holes through which the main lines 3 intersect is 0.05 meters, and the total length of 2000 mesh holes is the same as the width of the mesh panel. The width of a single mesh hole in the row of mesh holes without intersect is 0.08 meters, and the total length of 2000 mesh holes reaches 16 meters. In this way, while the mesh panel forms a net pocket structure between the two poles, the total length of the mesh holes in the intersect area is adapted to the width of the mesh panel, which restricts the sliding displacement of mesh panel 2 along the main lines 3. Compared with the traditional method of manually adding auxiliary lines and tying knots, this greatly reduces the frequency of maintenance and workload.

[0023] When bird netting is covered with lightweight items such as plastic bags and wrapping paper, the operator pulls handle 711, causing displacement block 710 to slide within displacement groove 74. Displacement block 710 is then moved out of displacement groove 74 and rotated into stop hook 75, limiting its position. At this point, positioning rod 78 disengages from positioning hole 73, and support base 6 can slide on base plate 5. By sliding the two support bases 6 closer together, the position is adjusted, and then the operation is reversed to re-insert positioning rod 78 into corresponding stop hole 76, fixing support base 6 in its new position. This operation shortens the horizontal distance between the two net poles 1, preventing damage to the main line 3 or netting due to excessive force on netting 2 during subsequent lowering of net poles 1. Then, the bolts and nuts between support block 4 and support base 6 are loosened. During this process, support assembly 8 can provide auxiliary support for 1. Then, net pole 1 is rotated to tilt or even flatten netting 2, allowing workers to clean lightweight items from the netting on the ground without climbing.

[0024] After cleaning, the support component 8 is used to help support the net pole 1 back to a vertical position. The support ring 84 at the top of the support rod 83 provides auxiliary support force. After the net pole 1 is adjusted to a vertical position, the bolts and nuts are tightened to fix it. Then, the spring 79 of the limiting component 7 pushes the positioning rod 78 to reset, so that the displacement block 710 disengages from the stop hook 75 and slides back into the displacement groove 74. The positioning rod 78 is inserted into the positioning hole 73 to complete the limiting and fixing of the support seat 6, so that the bird net is restored to normal working state.
