Description

Technical Field

[0001] This utility model relates to the field of agricultural and grassland rodent control technology, specifically an isolation device for controlling underground rodents. Background Technology

[0002] In my country's grasslands and agricultural areas, especially in high-altitude pastoral areas such as the Qinghai-Tibet Plateau, underground rodent infestations (such as the plateau mole rat) are rampant. These rodents burrow and gnaw on plant roots, leading to grassland degradation, soil erosion, and decreased agricultural yields, causing serious harm to the ecological environment and animal husbandry. Current control methods have significant limitations: while chemical baiting is fast-acting, it easily causes environmental pollution, rodent resistance, and the risk of poisoning in humans and livestock, and there is also the risk of rapid rodent resurgence. Simple physical isolation ditches (such as straight-board fences only 50-60 cm deep) are inadequate due to insufficient burial depth or structural issues. Design flaws make it easy for highland mole rats, which are adept at digging, to bypass or burrow through the ground, resulting in a lack of long-lasting control effects. Some existing patented technologies, such as "A Grassland Prevention Device for Underground Rats" (CN219500278U), although using mechanical baiting tubes, rely on baiting rather than barrier. While "A Rodent Control Isolation Trenching and Netting Device" (CN115573414A) involves trenching and netting, it does not solve the key problems of deep barrier and preventing climbing. Therefore, there is an urgent need for a sustainable control device that can adapt to high-altitude and cold environments, provide thorough barrier protection, and coordinate with ecological management. Summary of the Invention

[0003] The purpose of this invention is to provide an isolation device for controlling underground rats, in order to solve the problem mentioned in the background art where insufficient burial depth of the isolation device leads to rats digging through the soil from the bottom of the fence.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an isolation device for controlling underground rodents, comprising a narrow trench, wherein the trench is excavated around the control area, and an L-shaped base is buried inside the trench. The L-shaped base extends horizontally inward or outward, and a sheet metal plate is inserted and installed at the other end of the frame. The sheet metal plate is designed to be inclined and tilted towards the L-shaped base. The outer surface of the L-shaped base is in contact with the outer surface of the trench. A wire fence is fixedly installed on the outer surface of the frame, and the inside of the trench is filled with backfill soil.

[0005] Preferably, one end of the sheet metal is inserted into the frame, and a first fixing bolt is threaded onto the outer surface of the frame, with the outer surface of the first fixing bolt fitting against the outer surface of the sheet metal.

[0006] By adopting the above technical solution, the sloping and smooth design of the sheet metal can effectively prevent rodents from crossing over from the ground into the control area. The sheet metal is made of galvanized snowflake sheet metal and can be easily fixed to the outer surface of the frame with the first fixing bolt. This facilitates the replacement and assembly of the sheet metal while preventing rodents from crossing over from the ground.

[0007] Preferably, a portion of the L-shaped base, frame, and wire fence is located inside the groove, with one end of the wire fence and sheet metal plate protruding from the groove.

[0008] By adopting the above technical solution, the L-shaped base, frame, wire fence and sheet metal can be buried deep, and part of the wire fence and sheet metal can be exposed in the groove, so that the prevention and control isolation device can be buried deeper, thereby reducing the risk of rodents digging too deep and passing through the prevention and control isolation device.

[0009] Preferably, the wire fence has a mesh structure and is made of galvanized high-strength steel wire welded together.

[0010] The above technical solution can prevent rodents from passing through the wire fence, and the material of the wire fence ensures that it will not break or fail due to rust after being buried in the trench and filled with backfill soil.

[0011] Preferably, the outer surfaces of both sides of the L-shaped base are threaded with second fixing bolts, and the outer surfaces of the second fixing bolts are in contact with the outer surfaces of the frame. A buckle is fixedly installed on one side of the L-shaped base, and the buckle engages with another L-shaped base. A third bolt is threaded on the outer surface of the L-shaped base, and the third bolt engages with the buckle.

[0012] By adopting the above technical solution, the L-shaped base can be connected and fixed to the frame by the second fixing bolt, and can be connected to the third bolt by the buckle, so that the isolation and control device can be easily transported during handling and can be firmly connected and fixed together, improving the convenience and stability of installation.

[0013] Preferably, a fixing nose is fixedly welded to one side of the frame, and the fixing nose is fitted to another frame, and the frame and the fixing nose are connected by screws.

[0014] By adopting the above technical solution, the frame can be effectively connected and fixed together by fixing the nose and screws, thereby further improving the robustness of the isolation device.

[0015] Preferably, sleeves are rotatably mounted on both outer surfaces of the frame, and insert rods are slidably mounted on the outer surfaces of the sleeves. A lever is provided on one outer surface of the insert rod, and the lever faces the wire fence. The insert rod is inserted into the outer surfaces of both sides of the groove. A handle fixing rod is threadedly mounted on the outer surface of the sleeve, and the outer surface of the handle fixing rod is in contact with the outer surface of the insert rod. Fixing screws are threadedly mounted on both outer surfaces of the frame, and the outer surface of the fixing screws penetrates the outer surface of the sleeve. The sleeve and the fixing screws are rotatably connected.

[0016] By adopting the above technical solution, the direction of the fixing sleeve is adjusted by fixing screws, and the insertion rod can be easily inserted into both sides of the trench by lever rod. The position of the insertion rod is fixed by tightening the handle fixing rod. With the design of the L-shaped base, the frame can be supported and fixed, reducing the time when backfill soil is poured into the trench and compacted, so that the frame will not move and cause the overall tilting and displacement of the prevention and control isolation device.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the isolation device for controlling underground rats: 1. The L-shaped base design and the wire mesh fence inside the frame prevent rodents from digging underground. The wire mesh fence also prevents rodents from digging downwards when they encounter the wire mesh fence. Furthermore, the L-shaped base, frame, and wire mesh fence are buried 1.5 meters deep at the bottom of the trench, which greatly reduces the amount of soil rodents need to dig through from the bottom of the control and isolation device. This significantly reduces the damage caused by rodents crossing the control area, reduces the amount of chemical agents used, reduces the impact of drugs on the environment and non-target organisms, and greatly improves the effectiveness of rodent control. 2. The exposed frame, wire fence, and sheet metal plate on the outside of the ditch prevent rodents from climbing over the control and isolation device when on the ground. The wire fence can block rodents from passing on the ground, and the inclined and smooth design of the sheet metal plate makes it impossible for rodents to climb over the sheet metal plate to enter the control area. This further reduces the damage caused by rodents climbing over the isolation device on the ground and further improves the effectiveness of rodent control. 3. The L-shaped base design enhances the anchoring effect of the control device in the soil. With the rotation of the sleeve and the leverage of the lever, the insertion rod can be firmly inserted into the outer surface of the trench at an angle. Then, the angle of the sleeve is fixed by the fixing screw, and the position of the insertion rod is fixed by the handle fixing rod, which further strengthens the firmness of the control and isolation device and extends the overall service life of the isolation device. 4. When assembling the L-shaped base, frame, wire fence, and sheet metal, it is necessary to use snaps and fixing noses for assembly, third bolts and screws for fixing, and second fixing bolts and first fixing bolts for tightening and fixing. This allows the prevention and control isolation devices to be connected and assembled together, greatly improving the convenience and sturdiness of installation and docking, and reducing the space required for moving and transporting the prevention and control isolation device components, further improving the convenience of installation and handling.

[0020] 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.

[0021] Please see Figure 1-6This utility model provides a technical solution: an isolation device for underground rodent control, including a narrow ditch 1, which is excavated around the control area, and an L-shaped base 2 is buried inside the narrow ditch 1. The L-shaped base 2, a frame 3, and a portion of a wire fence 4 are located inside the narrow ditch 1. One end of the wire fence 4 and a sheet metal plate 5 protrudes from the narrow ditch 1. The L-shaped base 2 extends horizontally inward or outward, and the other end of the frame 3 is inserted and installed with a sheet metal plate 5. The sheet metal plate 5 is designed to be inclined and tilted towards the L-shaped base 2. The outer surface of the L-shaped base 2 is in contact with the outer surface of the narrow ditch 1. The outer surface of the frame 3 is fixedly installed with a wire fence 4, which is a mesh structure made of galvanized high-strength steel wire. The interior of the narrow ditch 1 is filled with backfill soil 16.

[0022] The sheet metal is 20 cm wide. The total height of the L-shaped base, frame, wire fence, and sheet metal is 1.8 meters. The depth of the groove is 1.5 meters. The portion of the wire fence and sheet metal protruding from the groove is 0.3 meters. The mesh size of the wire fence is no larger than 1.0 cm × 1.0 cm. The wire fence is made of galvanized high-strength steel wire (zinc layer thickness ≥ 30 μm). The bottom width of the L-shaped base is 20 cm.

[0023] First, when using this device, a small trench 1 needs to be dug in the control area. Then, the L-shaped base 2 is placed at the bottom of the trench 1, and the frame 3, wire fence 4, and sheet metal 5 are assembled and connected in sequence, so that part of the L-shaped base 2, frame 3, and wire fence 4 can be buried deep underground. The trench 1 can be filled back with backfill soil 16 and compacted. When rodents are digging underground, they can be blocked by the wire fence 4. When rodents try to dig around the obstacle, they can be blocked again by the L-shaped base 2. This effectively blocks rodents from digging under the control device and prevents them from digging through the soil, greatly improving the control effect on rodents.

[0024] One end of the sheet metal plate 5 is inserted into the frame 3. The outer surface of the frame 3 is threaded with a first fixing bolt 6, and the outer surface of the first fixing bolt 6 is in contact with the outer surface of the sheet metal plate 5.

[0025] Secondly, the exposed section of the wire mesh fence 4 and sheet metal 5 in the narrow ditch 1 can effectively intercept rodents passing through the ground, preventing them from crossing and climbing the smooth and sloping sheet metal 5, thus further enhancing the rodent control and isolation effect of the control and isolation device on the ground.

[0026] The outer surfaces of both sides of the L-shaped base 2 are threaded with second fixing bolts 7, and the outer surfaces of the second fixing bolts 7 are in contact with the outer surfaces of the frame 3. A fixing nose 10 is fixedly welded to one side of the frame 3, and the fixing nose 10 is in contact with another frame 3. The frame 3 and the fixing nose 10 are connected by screws. A buckle 8 is fixedly installed on one side of the L-shaped base 2, and the buckle 8 is engaged with another L-shaped base 2. A third bolt 9 is threaded on the outer surface of the L-shaped base 2, and the third bolt 9 is inserted into the buckle 8.

[0027] Furthermore, when assembling the L-shaped base 2, frame 3, wire fence 4, and sheet metal 5 together, the L-shaped base 2, frame 3, and sheet metal 5 can be easily fixed together by the first fixing bolt 6 and the second fixing bolt 7. The L-shaped base 2 and frame 3 can be connected together by the buckle 8 and the fixing nose 10, and the two prevention and control isolation devices can be connected together by the third bolt 9 and screws. This allows the prevention and control isolation devices to be easily connected and fixed together, greatly improving the convenience and sturdiness when transporting and assembling the prevention and control isolation devices.

[0028] Sleeves 11 are rotatably mounted on the outer surfaces of both sides of frame 3, and insert rods 12 are slidably mounted on the outer surfaces of sleeves 11. A lever 13 is provided on one outer surface of insert rod 12, and the lever 13 faces the wire fence 4. Insert rod 12 is inserted into the outer surfaces of both sides of the groove 1. A handle fixing rod 14 is threadedly mounted on the outer surface of sleeve 11, and the outer surface of handle fixing rod 14 is in contact with the outer surface of insert rod 12. Fixing screws 15 are threadedly mounted on the outer surfaces of both sides of frame 3, and the outer surface of fixing screws 15 penetrates the outer surface of sleeve 11. Sleeve 11 and fixing screws 15 are rotatably connected.

[0029] Furthermore, after assembling the L-shaped base 2, frame 3, wire fence 4, and sheet metal 5 together, to ensure the stability and verticality of the overall control and isolation device when filling the backfill soil 16 into the ditch 1, simply rotate the sleeve 11 and insert the insertion rod 12 into the outer surfaces of both sides of the ditch 1 through the lever 13. Then, fix the position of the sleeve 11 through the fixing screw 15 and fix the position of the insertion rod 12 through the handle fixing rod 14, so that the control and isolation device can be fixed inside the ditch 1. And with the shape of the L-shaped base 2, when the backfill soil 16 is placed into the ditch 1 and compacted, the control and isolation device will not shift due to the filling soil or other reasons, further improving the accuracy of the control and isolation device installation.

[0030] Working principle: When setting up the rodent control and isolation device, simply dig a 1.5-meter-deep trench 1 in the area where rodent control is needed. Then, connect and fix the L-shaped base 2, frame 3, wire fence 4, and sheet metal 5 together using the first fixing bolt 6 and the second fixing bolt 7. Next, place the entire rodent control and isolation device into the trench 1, and interlock multiple devices with the fixing nose 10 using the clips 8. Extend the device by fixing it with the screws using the third bolt 9. Then, rotate the sleeve 11 and use the lever 13 to insert the insertion rod 12 into the trench 1. Finally, it can be manually... The handle fixing rod 14 is fixed to the fixing screw 15, so that when the backfill soil 16 is filled into the trench 1 and compacted, the control and isolation device will not shift due to impact or trampling. When the rats are digging underground, they can be blocked by the wire fence 4 and the L-shaped base 2. When they are on the ground, they can be blocked by another part of the wire fence 4. The smoothness and inclination of the sheet metal 5 prevent the rats from climbing and crossing the control and isolation device, which greatly improves the control effect of rats. It can also effectively carry out manual capture in the isolated and closed area, and achieve precise removal of the rat population in the area without the need to use chemical agents to cause environmental pollution and accidental injury.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
