Description

Technical Field

[0001] The invention belongs to the technical field of sand prevention and control, and specifically relates to a sand prevention and control device and method. Background Art

[0002] Sand prevention and control is a series of activities carried out to prevent land desertification, control desertified land, maintain ecological security, and promote sustainable economic and social development. Among them, protecting trees is one of the steps in sand prevention and control. By protecting trees, we can prevent them from being eroded by wind and sand and improve their survival rate.

[0003] The patent with the announcement number CN220023745U discloses a device for protecting early-stage vegetation from sand and desertification, including a main body mechanism, a limiting mechanism and an installation mechanism, wherein the limiting mechanism is located above the main body mechanism, and the installation mechanism is located at the left end of the main body mechanism, wherein the main body mechanism includes a device body, a special-shaped bearing plate and an arc-shaped limiting plate, wherein the special-shaped bearing plate is fixedly installed above the device body. The device for protecting early-stage vegetation from sand and desertification, by installing the main body mechanism, realizes that the device body provides good buffering and protection effects for trees in the early-stage planting period while supporting them, the design of the shock-absorbing damper can absorb the longitudinal vibrations suffered by the trees, and the design of the buffer spring and the arc-shaped rubber plate can buffer the lateral vibrations suffered by the trees, so as to reduce the phenomenon of the trees being overturned or broken due to the influence of natural factors, thereby improving the protection of the device body.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although trees can be clamped to prevent them from falling or breaking when hit by strong winds, when trees are in nature reserves, there are usually some wild animals in these areas. When food is scarce, they may gnaw on the bark of the trees, causing damage to the trees and reducing the survival rate of the trees. In addition, when some larger wild animals climb along the tree trunks, their claws may scratch the bark, causing it to peel off, or even cause the branches of the trees to break, affecting the growth of the trees. Especially for some relatively expensive trees, once they are gnawed and damaged by wild animals, it will cause great losses.

[0017] Preferably, fastening screws are provided at both the front and rear ends of the left and right sides of the base.

[0018] A method for preventing and controlling sand, comprising the following specific steps:

[0019] S1. Place the base on the tree to be protected and use multiple fastening screws to firmly connect the base to the ground;

[0020] S2. In the initial state, the casing 1 and the casing 2 are in a separated state. After the tree is between the casing 1 and the casing 2, the two-way threaded rod is manually rotated to make the casing 1 and the casing 2 slide together and approach each other until they fit together. At this time, the insertion rod 1 is inserted into the arc plate 1, and the insertion rod 2 is inserted into the casing 4. Then, according to the height of the tree trunk, the arc plate 2 is driven to rise. Because the insertion rod 1 is plugged into the arc plate 1, the arc plate 1 and the arc plate 2 rise synchronously, and the casing 3 and the casing 4 also rise synchronously, so that the casing 3 and the casing 4 can be raised as much as possible without squeezing the branches and leaves, so as to cover the tree to the greatest extent;

[0021] S3, rotating the threaded rods 2 on both sides to move the limit plates on both sides and contact the tree, so as to clamp the tree;

[0022] S4, when the wild animal jumps or climbs upward along the casing one, the casing three and the casing four are squeezed by external force, the sliding column slides downward, and the spring is squeezed, so that the sliding column squeezes the pressure sensor. When the pressure sensor detects a pressure signal, the gear two reciprocates, and the limit rod and the push plate move. Under the action of multiple push plates, the climbing wild animal can be pushed away from the casing three and the casing four;

[0023] S5. When the push plate moves, the gear 1 will rotate under the action of the rack, so that the rotating column will rotate, and the bumps on its surface will continue to rotate, so as to weaken the grasping stability of the wild animal, making it difficult for it to maintain balance, so as to further improve the effect of expelling wild animals;

[0024] S6. When the wild animal is away from the third and fourth protective tubes, the spring returns to its original state, the pressure sensor cannot detect any pressure, and the motor stops working.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The sand prevention and control device and method described in the present invention, in the initial state, the casing one and the casing two are in a separated state, and then the tree to be protected is placed between the two limit plates, and then the threaded rods two on both sides are manually rotated to make the limit plates on both sides move and contact the tree, so that the tree can be clamped, thereby playing a role in fixing the tree, thereby preventing the tree from loosening or being blown down.

[0027] 2. The sand prevention and control device and method described in the present invention utilizes an anti-gnawing shield mechanism to cover the trees with protective tubes one, two, three and four according to the height of the tree trunks, so as to prevent the trees from being eroded by wind and sand. At the same time, it also prevents wild animals from gnawing and scratching the bark of the trees, thereby ensuring the normal growth of the trees and improving the survival rate of the trees. Moreover, when wild animals climb or jump above protective tubes three and four and damage the branches and leaves of the trees, the pressure sensor detects the pressure signal and drives multiple limit rods and push plates to move back and forth at the same time. Under the action of the multiple push plates, the climbing wild animals can be pushed away from protective tubes three and four, thereby preventing the wild animals from falling into protective tubes one, two and three. The cavity formed by the three and four protective tubes makes it difficult for wild animals to climb out of the cavity. At the same time, it also avoids the situation where wild animals cause damage to the branches and leaves of trees when they are above the three and four protective tubes. In addition, when the push plate moves, the gear one will rotate under the action of the rack, so that the rotating column will rotate, and the protrusions on its surface will continue to rotate. Moreover, since the force generated by the rotation is dynamic, it can not only exert thrust but also generate lateral shear force, which helps to weaken the grip stability of the wild animal and make it difficult for it to maintain balance, and then fall from the three and four protective tubes, further improving the pushing effect of the push plate on the wild animal. In addition, compared with directly using violent means to drive away wild animals, this method is gentler and non-lethal, which helps to protect the life safety of wild animals.

[0028] 3. The sand prevention and control device and method described in the present invention utilizes a plurality of fastening screws to firmly connect the base to the ground, thereby ensuring the stability of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Specifically, sand prevention and control is a series of activities carried out to prevent land desertification, control desertified land, maintain ecological security, and promote sustainable economic and social development. Among them, protecting trees is one of the steps of sand prevention and control. By protecting trees, trees can be prevented from being eroded by wind and sand, so as to improve the survival rate of trees. When the existing sand prevention and control devices are used, they clamp trees to prevent them from falling or breaking when they are attacked by strong winds. However, when trees are in nature reserves, there are usually some wild animals in these areas. When they are short of food, they may gnaw on the bark of trees, thereby damaging the trees and reducing the survival rate of trees. In addition, when some large wild animals climb along the trunks, their claws may scratch the bark, causing the bark to peel off, or even cause the branches of the trees to break, affecting the growth of the trees. Especially for some relatively expensive trees, once they are gnawed and damaged by wild animals, it will cause great losses.

[0051] Therefore, in order to solve the above problems, in the present embodiment, when in use, the bidirectional threaded rod 3 is manually rotated, so that the casing 1 4 and the casing 2 5 can slide and approach each other at the same time until they fit together. At this time, the insertion rod 1 29 is inserted into the arc plate 1 11, and the insertion rod 2 30 is inserted into the casing 4 7. Then, according to the height of the tree trunk, the threaded rod 1 8 is manually rotated to drive the arc plate 2 12 to rise. Because the insertion rod 1 29 is plugged into the arc plate 1 11, the arc plate 1 11 and the arc plate 2 12 rise synchronously, and the casing 3 6 and the casing 4 7 also rise synchronously, that is, the casing 3 6 and the casing 4 7 can be raised as much as possible without squeezing the branches and leaves, so as to cover the trees to the greatest extent, to prevent the trees from being eroded by wind and sand, and at the same time, to avoid the situation where wild animals gnaw and scratch the bark of the trees, thereby ensuring the normal growth of the trees and the survival rate of the trees.

[0052] When the casing three 6 and the casing four 7 are combined, the connecting plate 26 is installed on the inner side of the casing three 6 and the casing four 7 by bolts;

[0053] When wild animals jump or climb upward along the protective tube 1 4, they may fall into the cavity formed by the protective tube 1 4, the protective tube 2 5, the protective tube 3 6, and the protective tube 4 7, which will cause trouble for the wild animals to climb out of the cavity. In addition, when wild animals climb or jump above the protective tube 3 6 and the protective tube 4 7, it is also easy to damage the branches and leaves of the trees. Therefore, when the above situation occurs, the protective tube 3 6 and the protective tube 4 7 are squeezed by external force, the sliding column 13 slides downward, and the spring 14 is squeezed, so that the sliding column 13 squeezes the pressure sensor 32. When the pressure sensor 32 detects a pressure signal, the motor 20 starts. , and drives the gear 25 to rotate back and forth, so that the inclined groove ring 23 rotates back and forth outside the mounting ring 15, and the inclined groove can be used to drive multiple guide columns 21 to move radially at the same time, so that the limit rod 16 and the push plate 27 can move, and under the action of multiple push plates 27, the climbing wild animals can be pushed away from the casing 3 6 and the casing 4 7, thereby avoiding the situation that the wild animals fall into the cavity formed by the casing 1 4, the casing 2 5, the casing 3 6, and the casing 4 7, making it difficult for the wild animals to climb out of the cavity. At the same time, it also avoids the situation that the wild animals damage the branches and leaves of the trees when they are above the casing 3 6 and the casing 4 7;

[0054] When the push plate 27 pushes the wild animal, the claws of some wild animals with strong gripping force may grip the push plate 27. For example, some cats such as leopards and tigers are difficult to push away by simple linear push. Therefore, when the push plate 27 moves, the gear 19 will rotate under the action of the rack 18, so that the rotating column 17 rotates, and the protrusion 31 on its surface will continue to rotate. In addition, since the force generated by the rotation is dynamic, it can not only apply thrust but also generate lateral shear force, which helps to weaken the grip stability of the wild animal and make it difficult for it to maintain balance, and then fall from the protective tube 3 6 and the protective tube 4 7, further improving the effect of expelling wild animals. In addition, compared with directly using violent means to drive away wild animals, this method is gentler and non-lethal, which helps to protect the life safety of wild animals. When the wild animal is away from the protective tube 3 6 and the protective tube 4 7, the spring 14 recovers, the pressure sensor 32 cannot detect the pressure, and the motor 20 stops working.

[0055] Thus, by utilizing the anti-gnawing shield mechanism, the protective tube 1 4, protective tube 2 5, protective tube 3 6, and protective tube 4 7 can cover the trees according to the height of the tree trunk, so as to prevent the trees from being eroded by wind and sand. At the same time, it also prevents wild animals from gnawing and scratching the bark of the trees, thereby ensuring the normal growth of the trees and improving the survival rate of the trees. In addition, when wild animals climb or jump over the protective tube 3 6 and protective tube 4 7 and damage the branches and leaves of the trees, the pressure sensor 32 detects the pressure signal and drives the multiple limit rods 16 and the push plates 27 to move back and forth at the same time. Under the action of the multiple push plates 27, the climbing wild animals can be pushed away from the protective tube 3 6 and protective tube 4 7, thereby preventing the wild animals from falling into the protective tube 1 4, protective tube 2 5, protective tube 3 6, and protective tube 4 7. The cavity makes it difficult for wild animals to climb out of the cavity. At the same time, it also avoids the situation where wild animals cause damage to the branches and leaves of trees when they are above the protective tubes three 6 and four 7. Moreover, when the push plate 27 moves, the gear 19 will rotate under the action of the rack 18, so that the rotating column 17 rotates, and the protrusion 31 on its surface will continue to rotate. Moreover, since the force generated by the rotation is dynamic, it can not only apply thrust but also generate lateral shear force, which helps to weaken the grip stability of the wild animal and make it difficult for it to maintain balance, and then fall from the protective tubes three 6 and four 7, further improving the pushing effect of the push plate 27 on the wild animal. Moreover, compared with directly using violent means to drive away wild animals, this method is gentler and non-lethal, which helps to protect the life safety of wild animals.

[0056] In this embodiment, Figure 1 and Figure 6 As shown, fastening screws 2 are provided at both the left and right sides and the front and rear ends of the base 1;

[0057] Specifically, the base 1 can be firmly connected to the ground by using a plurality of fastening screws 2, thereby ensuring the stability of the entire device.

[0058] A method for preventing and controlling sand, comprising the following specific steps:

[0059] S1. Place the base 1 at the tree to be protected, and use a plurality of fastening screws 2 to firmly connect the base 1 to the ground;

[0060] S2, in the initial state, the casing 1 4 and the casing 2 5 are in a separated state. After the tree is between the casing 1 4 and the casing 2 5, the two-way threaded rod 3 is manually rotated to make the casing 1 4 and the casing 2 5 slide together and approach each other until they fit together. At this time, the insertion rod 1 29 is inserted into the arc plate 1 11, and the insertion rod 2 30 is inserted into the casing 4 7. Then, according to the height of the tree trunk, the arc plate 2 12 is driven to rise. Because the insertion rod 1 29 is plugged into the arc plate 1 11, the arc plate 1 11 and the arc plate 2 12 rise synchronously, and the casing 3 6 and the casing 4 7 also rise synchronously, so that the casing 3 6 and the casing 4 7 can be raised as much as possible without squeezing the branches and leaves, so as to cover the tree to the greatest extent;

[0061] S3, rotating the threaded rods 10 on both sides, so that the limit plates 9 on both sides move and contact the tree, and the tree can be clamped;

[0062] S4, when the wild animal jumps or climbs upward along the protective tube 1 4, the protective tube 3 6 and the protective tube 4 7 are squeezed by external force, the sliding column 13 slides downward, and the spring 14 is squeezed, so that the sliding column 13 squeezes the pressure sensor 32. When the pressure sensor 32 detects a pressure signal, the gear 2 25 reciprocates, and the limit rod 16 and the push plate 27 move. Under the action of multiple push plates 27, the climbing wild animal is pushed away from the protective tube 3 6 and the protective tube 4 7;

[0063] S5. When the push plate 27 moves, the gear 19 will rotate under the action of the rack 18, so that the rotating column 17 rotates, and the protrusion 31 on its surface will continue to rotate, so as to weaken the grasping stability of the wild animal and make it difficult for it to maintain balance, so as to further improve the effect of expelling wild animals;

[0064] S6. When the wild animal is away from the protective tube three 6 and the protective tube four 7, the spring 14 recovers, the pressure sensor 32 detects no pressure, and the motor 20 stops working.

[0065] Working principle: place the base 1 at the tree to be protected, and use multiple fastening screws 2 to firmly connect the base 1 to the ground; in the initial state, the casing 1 4 and the casing 2 5 are in a separated state. After the tree is between the casing 1 4 and the casing 2 5, manually rotate the two-way threaded rod 3 to make the casing 1 4 and the casing 2 5 slide simultaneously and approach each other until they fit together. At this time, the insertion rod 1 29 is inserted into the arc plate 1 11, and the insertion rod 2 30 is inserted into the casing 4 7. Then, according to the height of the tree trunk, the arc plate 2 12 is driven to rise. Because the insertion rod 1 29 is plugged into the arc plate 1 11, the arc plate 1 11 and the arc plate 2 12 rise synchronously, and the casing 3 6 and the casing 4 7 also rise synchronously, that is, without squeezing the branches and leaves, the casing 3 6 and the casing 4 7 can be raised as much as possible to cover the tree to the greatest extent; rotate the threaded rods 2 10 on both sides to move the limit plates 9 on both sides and contact the tree. The trees can be clamped; when wild animals jump or climb upward along the protective tube 1 4, the protective tube 3 6 and the protective tube 4 7 are squeezed by external force, the sliding column 13 slides downward, and the spring 14 is squeezed, which can cause the sliding column 13 to squeeze the pressure sensor 32. When the pressure sensor 32 detects a pressure signal, the gear 2 25 rotates back and forth, and the limit rod 16 and the push plate 27 move, and the climbing wild animals can be pushed away from the protective tube 3 6 and the protective tube 4 7 under the action of multiple push plates 27; when the push plate 27 moves, the gear 19 will rotate under the action of the rack 18, so that the rotating column 17 rotates, and the protrusion 31 on its surface will continue to rotate to weaken the grasping stability of the wild animal, making it difficult to keep balance, so as to further improve the effect of expelling wild animals; when the wild animal is away from the protective tube 3 6 and the protective tube 4 7, the spring 14 recovers, the pressure sensor 32 cannot detect the pressure, and the motor 20 stops working.

A method for preventing and controlling sand, characterized in that: The sand prevention and control device according to any one of claims 1 to 6 is used to carry out sand prevention and control, comprising the following specific steps: S1. placing the base (1) at the tree to be protected, and using a plurality of fastening screws (2) to firmly connect the base (1) to the ground; S2. In the initial state, the casing 1 (4) and the casing 2 (5) are in a separated state. After the tree is between the casing 1 (4) and the casing 2 (5), the bidirectional threaded rod (3) is manually rotated to make the casing 1 (4) and the casing 2 (5) slide simultaneously and approach each other until they fit together. At this time, the insertion rod 1 (29) is inserted into the arc plate 1 (11), and the insertion rod 2 (30) is inserted into the casing 4 (7). Then, according to the height of the tree trunk, the arc plate 2 (12) is driven to rise. Since the insertion rod 1 (29) is plugged into the arc plate 1 (11), the arc plate 1 (11) and the arc plate 2 (12) rise synchronously, and the casing 3 (6) and the casing 4 (7) also rise synchronously. Therefore, the casing 3 (6) and the casing 4 (7) can be raised without squeezing the branches and leaves, so as to cover the tree to the greatest extent. S3, rotating the threaded rods (10) on both sides to move the limit plates (9) on both sides to contact the tree, thereby clamping the tree; S4. When a wild animal jumps or climbs upward along the protective tube one (4), the protective tube three (6) and the protective tube four (7) are squeezed by an external force, the sliding column (13) slides downward, and the spring (14) is squeezed, so that the sliding column (13) squeezes the pressure sensor (32). When the pressure sensor (32) detects a pressure signal, the gear two (25) reciprocates, and the limit rod (16) and the push plate (27) move. Under the action of the plurality of push plates (27), the climbing wild animal is pushed away from the protective tube three (6) and the protective tube four (7); S5. When the push plate (27) moves, the gear (19) rotates under the action of the rack (18), thereby rotating the rotating column (17), and the protrusion (31) on its surface continues to rotate, thereby weakening the grasping stability of the wild animal, making it difficult for it to maintain balance, thereby further improving the effect of expelling wild animals; S6. When the wild animal moves away from the third protective tube (6) and the fourth protective tube (7), the spring (14) is restored, the pressure sensor (32) cannot detect the pressure, and the motor (20) stops working.
