Description

Technical Field

[0001] This utility model relates to the technical field of devices for controlling harmful organisms in water conservancy projects, and in particular to a protective cover and a device for controlling red imported fire ants. Background Technology

[0002] Red imported fire ants are widely distributed, highly adaptable, omnivorous, and have strong reproductive capacity and aggressiveness, making them one of the most destructive invasive species.

[0003] Red imported fire ants can cause serious ecological disasters in invaded areas, posing a major threat to biodiversity conservation and agricultural production. They can destroy turf and vegetation, leaving embankments riddled with holes, damaging soil stability, and causing soil erosion. Red imported fire ants can also damage public facilities, such as irrigation systems or power lines, causing equipment malfunctions and reducing work efficiency.

[0004] Currently, chemical methods are used to control red imported fire ants, employing baits to lure and kill them. However, these methods generally suffer from poor baiting ability, with the ants only consuming small amounts of the bait, failing to effectively kill them. Therefore, another approach involves directly spraying the ant nest with pesticides and then covering it, as illustrated in the red imported fire ant device disclosed in Chinese Patent Publication No. CN114680098B. However, the size of red imported fire ant nests varies. Using an overly large cover allows the ants to roam freely, requiring a larger area for spraying and increasing soil contamination. Conversely, using a cover that is too small results in incomplete eradication of the ants. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve at least one of the technical problems mentioned above.

[0006] The solution to the technical problem of this utility model is:

[0007] A protective cover comprising multiple protective panel assemblies;

[0008] Each of the aforementioned protective panel assemblies includes a base, a support rod, a crossbeam, and a shielding cloth. The lower end of the support rod is hinged to the base, the crossbeam is laterally disposed at the upper end of the support rod, the crossbeam and the support rod are fixedly connected, the upper side of the shielding cloth is fixedly connected to the crossbeam, and the lower side of the shielding cloth is fixedly connected to the base.

[0009] All the bases form a closed loop, and in two adjacent shield assemblies, the two adjacent shielding fabrics are connected by Velcro.

[0010] As a further improvement to the above technical solution, the length of the crossbeam is less than the length of the base.

[0011] As a further improvement to the above technical solution, in each of the protective plate assemblies, two support rods are provided, the lower ends of the two support rods are respectively hinged to the base, the crossbeam is fixedly connected to the upper ends of the two support rods, and the shielding cloth is provided with a plurality of first straps, which are used to bind to the support rods.

[0012] As a further improvement to the above technical solution, the bottom surface of the base is provided with multiple nails for driving into the soil.

[0013] As a further improvement to the above technical solution, the protective cover also includes multiple baffles made of elastic material. Two limiting sleeves are provided on the base. Limiting protrusions extend from both the left and right sides of the baffles. The baffles are disposed between two adjacent bases. The limiting protrusions on the left and right sides of the limiting protrusions are respectively inserted into the two adjacent limiting sleeves on the corresponding two bases.

[0014] As a further improvement to the above technical solution, each of the bases is provided with a blade, which is disposed in the closed loop and is used to insert into the soil.

[0015] As a further improvement to the above technical solution, the length of the shielding cloth in the left-right direction is greater than the length of the base, and the vertical centerline of the shielding cloth is located at the vertical centerline of the base.

[0016] As a further improvement to the above technical solution, each of the shielding cloths has a hook side of Velcro on the front of its left side and a fleece side of Velcro on the back of its right side. The difference between the length of the shielding cloth in the left-right direction and the length of the base in the left-right direction is a. The width of the hook side and the width of the fleece side are both greater than a / 2.

[0017] As a further improvement to the above technical solution, the shielding cloth is provided with a second strap, and the crossbeam and the shielding cloth are fixedly connected by the second strap.

[0018] This utility model also provides a red imported fire ant control device, including a support frame and a spraying mechanism installed on the support frame, as well as a protective cover as described in any of the above technical solutions.

[0019] The beneficial effects of this invention are as follows: In practical use, operators can determine the number of bases needed based on the actual size of the red imported fire ant nest, and then use the bases to surround the nest. Between two adjacent shielding sheets, operators can use Velcro to attach them together, creating a closed loop with an opening at the top. Operators can then spray pesticide through this opening, ensuring that the sprayed pesticide is concentrated within the space enclosed by the bases and shielding sheets. Furthermore, this design is adaptable to red imported fire ant nests of different sizes. Attached Figure Description

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0027] Reference Figures 1-4 A protective cover includes multiple protective panel assemblies; each protective panel assembly includes a base 1, a support rod 2, a crossbeam 4, and a shielding cloth 3. The lower end of the support rod 2 is hinged to the base 1, the crossbeam 4 is laterally disposed at the upper end of the support rod 2, the crossbeam 4 and the support rod 2 are fixedly connected, the upper side of the shielding cloth 3 is fixedly connected to the crossbeam 4, and the lower side of the shielding cloth 3 is fixedly connected to the base 1; all the bases 1 form a closed loop, and in two adjacent protective cover assemblies, two adjacent shielding cloths 3 are connected by Velcro.

[0028] As can be seen from the above, in actual use, the operator can determine the number of bases 1 needed based on the actual size of the red imported fire ant nest. The operator uses the bases 1 to surround the red imported fire ant nest. Between two adjacent shielding cloths 3, the operator can use Velcro to stick the two adjacent shielding cloths 3 together, thus forming a space with an opening at the top within the closed loop. The operator can spray pesticide at the opening, ensuring that the sprayed pesticide is concentrated as much as possible within the space enclosed by the bases 1 and the shielding cloths 3, and also adapting to red imported fire ant nests of different sizes.

[0029] In use, all the bases 1 can be arranged in a circular array to form a closed loop, with two adjacent bases 1 abutting against each other.

[0030] The base 1 and the support rod 2 are connected by a hinge. The hinge has a certain static friction force, which allows the support rod 2 to tilt or stand upright under the action of the friction force of the hinge, instead of tilting directly under the action of gravity.

[0031] In some embodiments, the length of the crossbeam 4 is less than the length of the base 1. This structure is simple and easy to install. Through this structure, the width of the space enclosed by multiple bases 1 and multiple shielding fabrics 3 gradually decreases from bottom to top, resulting in a relatively small opening at the top of the space and better sealing. Furthermore, adjacent shielding fabrics 3 are attached with Velcro, allowing for flexible adjustment of their attachment position and recognizing attachments at various angles.

[0032] In some embodiments, each of the protective panel assemblies includes two support rods 2, the lower ends of which are hinged to the base 1. The crossbeam 4 is fixedly connected to the upper ends of the two support rods 2. The shielding cloth 3 is provided with multiple first straps 33 for binding to the support rods 2. This structure is simple and easy to install. By providing two support rods 2, the shielding cloth 3 can be better supported.

[0033] In some embodiments, the bottom surface of the base 1 is provided with a plurality of nails 11 for embedding into the soil. This structure is simple and easy to install. By setting the nails 11, the base 1 can be inserted into the soil to improve the stability of the base 1.

[0034] In some embodiments, the protective cover further includes multiple baffles 51 made of elastic material. Two limiting sleeves 52 are provided on the base 1. Limiting protrusions extend from both the left and right sides of each baffle 51. The baffles 51 are positioned between two adjacent bases 1, and the limiting protrusions on both sides of each limiting protrusion are inserted into the adjacent limiting sleeves 52 on the corresponding two bases 1. The baffles 51 are positioned between two adjacent bases 1 and inserted into the corresponding limiting sleeves 52 on the adjacent bases 1 via the limiting protrusions, making installation very convenient. Furthermore, the lower side of the baffle 51 can be lower than the bottom surface of the base 1 so that the lower side of the baffle 51 can be inserted into the soil, thereby improving the sealing performance between adjacent bases 1.

[0035] In some embodiments, each of the bases 1 is provided with a blade 12, which is disposed in the closed loop and is used to insert into the soil. This structure is simple and easy to install, and the blade 12 inserted into the soil can further improve the sealing performance of the closed loop.

[0036] In some embodiments, the length of the shielding cloth 3 in the lateral direction is greater than the length of the base 1, and the vertical centerline of the shielding cloth 3 is located at the vertical centerline of the base 1. This structure is simple and easy to set up. With this structure, the shielding cloth 3 and the base 1 can be aligned, and it is also convenient to connect adjacent shielding cloths 3.

[0037] In some embodiments, each of the shielding fabrics 3 has a hook side 31 of Velcro on its left front side and a loop side 32 of Velcro on its right back side. The difference between the length of the shielding fabric 3 in the left-right direction and the length of the base 1 in the left-right direction is 'a'. The width of both the hook side 31 and the loop side 32 is greater than 'a / 2'. This structure is simple and easy to set up. With this structure, two adjacent shielding fabrics 3 can be fixedly connected by Velcro. For example, in two adjacent shielding fabrics 3, the loop side 32 on the right side of the left shielding fabric 3 is attached to the hook side 31 on the left side of the right shielding fabric 3.

[0038] In practical use, the front of the shielding cloth 3 refers to the side of the shielding cloth 3 that faces away from the closed loop, and the back of the shielding cloth 3 refers to the side of the shielding cloth 3 that faces the closed loop.

[0039] In some embodiments, the shielding cloth 3 is provided with a second strap 34, and the crossbeam 4 and the shielding cloth 3 are fixedly connected by the second strap 34. The second strap 34 allows the operator to adjust the tightness of the strap according to actual needs.

[0040] This utility model also provides a red imported fire ant control device, including a support frame and a spraying mechanism mounted on the support frame, as well as the protective cover described in any of the above technical solutions. Since the protective cover has already been described above, those skilled in the art should be able to understand it by referring to the accompanying drawings; therefore, further description of the protective cover is not required here.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
