Description

Technical Field

[0001] The present invention relates to the field of forest fire prevention, and particularly to a forest fire prevention protection isolation device. Background Art

[0002] The existing fire prevention isolation net, after being installed, is exposed to the complex and changeable outdoor environment for a long time. During the long-term use process, the long-term penetration of rainwater will soften the soil around the columns, weaken the supporting force of the soil on the columns. In this way, the columns of the fire prevention isolation net are extremely likely to loosen. As time goes by, this loosening becomes more and more serious, and finally leads to the collapse of the fire prevention isolation net, greatly weakening its original fire prevention isolation function.

[0003] At the same time, during the natural growth process, some plants will extend and grow towards the position of the fire prevention isolation net. Since they are tall plants, the growth and extrusion of the branches and trunks of the plants will also bring lateral pressure to the fire prevention isolation net. When this pressure accumulates to a certain extent, it may cause the fire prevention isolation net to be overwhelmed and then fall down.

[0004] In view of the above many problems, it is not difficult to see that the existing fire prevention isolation net has obvious deficiencies in dealing with the complex outdoor environment and the influence of plant growth. There is still a great room for improvement in its structural stability, dealing with plant interference, etc. Summary of the Invention

The top end of the pushing strip extends into the strip-shaped through-hole. A guiding assembly is arranged inside the strip-shaped through-hole. The guiding assembly is used to guide the pushing strip to slide on the wedge-shaped block during the movement of the conveying rod.

[0009] Preferably, the guiding assembly includes a transverse groove, a V-shaped groove, and a lower guiding groove. The transverse groove, the V-shaped groove, the lower guiding groove, and the second transverse groove are all formed in the inner wall of the strip-shaped through-hole. There are multiple V-shaped grooves. The multiple V-shaped grooves are arranged between adjacent transverse grooves. The lower guiding groove communicates with the transverse groove at the tail end. A first guiding pin is fixed on the side wall of the pushing strip. The first guiding pin is inserted into the transverse groove.

[0010] Preferably, a sliding groove is formed at the bottom of the drill bit. The sliding groove sleeves the outside of the storage cylinder. A sliding cylinder is fixed on the inner wall of the sliding groove. The sliding cylinder penetrates the storage cylinder and extends into the inside of the storage cylinder. A fixing plate is fixed on the surface of the sliding cylinder. A first pulling spring is fixed between the fixing plate and the inner wall of the storage cylinder. A plurality of ejecting plates are slidably connected to the side wall of the fixing plate. A second guiding pin is fixed on the side wall of the ejecting plate. A guiding groove is formed in the inner wall of the discharge port. The guiding groove is composed of an inclined groove and a straight groove. The second guiding pin is inserted into the guiding groove.

[0011] Preferably, a screw rod is fixed on the top surface of the slider. The screw rod is inserted into the sliding cylinder. A threaded sleeve is threadedly connected to the surface of the screw rod. The threaded sleeve is unidirectionally rotatably connected to the bottom surface of the sliding cylinder.

[0012] Preferably, a plurality of brackets are fixed on the inner wall of the push rod. A plug rod is slidably inserted on the bracket. A limiting plate is fixed on the surface of the plug rod.

The knob is coaxially fixed with the second bevel gear.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, after the conveying rod extends out from the through hole, the contact area between the bottom of the positioning column and the soil can be increased, thereby improving the stability of the positioning column and reducing the adverse effects of external factors on the stability of the positioning column.

[0016] Second, since a storage cylinder is arranged inside the conveying rod and plant seeds are arranged in the storage cylinder, after the conveying rod extends into the soil, the plant seeds are brought into the soil through the storage cylinder. As the seeds grow, the roots of the plants can wind around the positioning column and the conveying rod, which can further improve the stability of the positioning column. Some plants with short stature, soft leaves, relatively high water content and not easy to burn are selected to be combined with the upright column. In case of a fire, the spread of the fire can be effectively slowed down, and the growth of other tall and flammable plants can also be inhibited, thereby improving the anti-interference ability of the upright column.

[0017] Third, only part of the seeds are pushed out each time. Since the drill bit extends out at different soil depths each time, the seeds can be evenly dispersed in the soil at different heights, further expanding the dispersion range of the seeds. Thus, in the subsequent growth process of the seeds, they can be better wound and combined with the positioning column. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0026] Such as Figures 1 to 6A forest fire prevention protection isolation device shown in the figure includes a plurality of positioning columns 1. An isolation net 2 is fixed between adjacent positioning columns 1. The positioning column 1 is in a hollow state with an open top. A plurality of inclined conveying rods 3 are arranged inside the positioning column 1. Through holes 4 are formed on the surface of the positioning column 1. The ends of the conveying rods 3 are inserted into the through holes 4. A push plate 5 is arranged inside the positioning column 1. The push plate 5 is arranged above the plurality of conveying rods 3. The push plate 5 is slidably connected to the top ends of the conveying rods 3. A downward pressing assembly is arranged at the top end of the push plate 5. The downward pressing assembly is used to drive the push plate 5 to move downward. Storage grooves 6 are formed on the surface of the conveying rods 3. Storage cylinders 7 for storing seeds are arranged in the storage grooves 6. Ventilation through holes 8 are formed on the bottom surface of the storage cylinder 7. Ventilation through grooves 9 with open tops are formed inside the conveying rods 3. Communication holes 10 communicating with the inside of the ventilation through grooves 9 are formed at the bottom of the storage grooves 6. Strip-shaped through grooves 11 communicating with the inside of the ventilation through grooves 9 are formed on the surface of the push plate 5.

[0027] Specifically, the bottom of the positioning column 1 is conical. During installation, the bottom of the positioning column 1 is inserted into the soil. Then, the pushing assembly is started. The pushing assembly drives the push plate 5 to slide downward inside the positioning column 1. The push plate 5 pushes the conveying rods 3 downward. After the conveying rods 3 extend out of the through holes 4, the contact area between the bottom of the positioning column 1 and the soil can be increased, thereby improving the stability of the positioning column 1 and reducing the adverse effects of external factors on the stability of the positioning column 1. Further, since storage cylinders 7 are arranged inside the conveying rods 3 and plant seeds are arranged in the storage cylinders 7, after the conveying rods 3 extend into the soil, the plant seeds are brought into the soil through the storage cylinders 7. As the seeds grow, the roots of the plants can wind around the positioning column 1 and the conveying rods 3, which can further improve the stability of the positioning column 1. For example, when using Ophiopogon japonicus seeds for planting, the roots will penetrate deep into the soil and intertwine with each other during growth, which can effectively fix the soil and play a good role in strengthening the soil around the positioning column 1. Moreover, as Ophiopogon japonicus grows, the roots will continuously increase and grow stronger, and the strengthening effect will gradually increase. And, Ophiopogon japonicus grows densely and can form a dense ground cover layer. By competing for sunlight, water, and nutrients, it can inhibit the growth of other tall and flammable plants, thereby improving the anti-interference ability of the column. And some plants with short plants, soft leaves, and relatively high water content and not easy to burn can be selected to be combined with the column. During a fire, it can also effectively slow down the spread of the fire. It should be noted that when some plant seeds are buried too deep, it may be difficult to contact the outside air, resulting in difficulty in germinating and growing. To solve the above problems, in the present invention, the positioning column 1 is set in a hollow state with an open top. The outside air can enter the inside of the column from the top and contact the plant seeds after passing through the strip-shaped through grooves 11, the ventilation through grooves 9, and the ventilation through holes 8, thereby avoiding the situation that the seeds are buried too deep, affecting the growth of the seeds and reducing the stability of the column. And a protective cover can be arranged at the top end of the positioning column 1 to avoid blockage.

[0028] As a further embodiment of the present invention, a drill bit 12 is provided at one end of the storage cylinder 7 away from the air-permeable through-hole 8. A discharge port 13 is formed on the side wall of the storage cylinder 7. A positioning film 14 is fixed on the inner wall of the discharge port 13. Seed positioning holes 15 are formed on the positioning film 14. The seed positioning holes 15 communicate with the inside of the storage cylinder 7. A pushing component is arranged in the communication hole 10, and the pushing component is used to rotate and push out the storage cylinder 7.

[0029] Specifically, during the insertion process of the conveying rod 3, due to the extrusion effect, some of the soil around the conveying rod 3 may be relatively compact, which affects the germination of seeds and further affects the winding and combination of the plant roots with the column. To solve the above problems, the present invention provides a drill bit 12 at the top of the storage cylinder 7, and by arranging a pushing component, during the process of the conveying rod 3 extending out, the storage cylinder 7 is rotated and pushed out through the pushing component, so as to rotate and push out the drill bit 12, re-disperse the soil, and insert the storage cylinder 7 into the dispersed soil, which can create many favorable conditions for seed germination and plant growth. The loose soil particles have large pores, which can provide sufficient oxygen for the seeds to meet the respiratory needs, and can also allow water to penetrate quickly and adsorb an appropriate amount of water, which is beneficial for the seeds to absorb and maintain an appropriate humidity, thus promoting the seeds to germinate faster and better, and enabling the plant roots to better wind and combine with the positioning column 1.

[0030] As a further embodiment of the present invention, the pushing component includes a hollow pushing rod 16. The pushing rod 16 is threadedly connected inside the communication hole 10. One end of the pushing rod 16 is fixed to the storage cylinder 7. A slider 17 is rotatably connected to the other end of the pushing rod 16. A wedge-shaped block 18 is fixed on the inner wall of the air-permeable groove 9. A pushing strip 19 is slidably connected to the inclined surface of the wedge-shaped block 18. The slider 17 is slidably connected to the pushing strip 19. A first spring 20 is fixed between the slider 17 and the air-permeable groove 9. The top end of the pushing strip 19 extends into the strip-shaped through groove 11. A guiding component is arranged inside the strip-shaped through groove 11, and the guiding component is used to guide the pushing strip 19 to slide on the wedge-shaped block 18 during the movement of the conveying rod 3.

[0031] Specifically, during the process of the pushing plate 5 pushing the conveying rod 3 downward, the conveying rod 3 slides along the bottom surface of the pushing plate 5. During the sliding process, it can drive the pushing strip 19 to move inside the strip-shaped through groove 11. A guiding component is arranged inside the strip-shaped through groove 11, and the guiding component can guide the pushing strip 19 to slide on the wedge-shaped block 18. Under the guiding action of the wedge-shaped block 18, the pushing strip 19 can be guided to move toward the side close to the storage groove 6, and the pushing rod 16 is driven to move synchronously. The storage cylinder 7 and the drill bit 12 are pushed by the pushing rod 16 and inserted into the soil. Moreover, the pushing rod 16 is threadedly connected to the communication hole 10. Therefore, during the movement of the pushing rod 16, it can rotate synchronously, so that the drill bit 12 can rotate synchronously during the process of inserting into the soil, disperse the soil, and provide favorable conditions for seed growth.

[0032] As a further embodiment of the present invention, the guiding component includes a horizontal groove 21, a V-shaped groove 22, and a lower guiding groove 23. The horizontal groove 21, the V-shaped groove 22, the lower guiding groove 23, and the second horizontal groove 21 are all formed on the inner wall of the strip-shaped through groove 11. There are multiple V-shaped grooves 22, and the multiple V-shaped grooves 22 are arranged between adjacent horizontal grooves 21. The lower guiding groove 23 communicates with the horizontal groove 21 at the tail end. A first guiding pin 24 is fixed on the side wall of the pushing bar 19, and the first guiding pin 24 is inserted into the horizontal groove 21.

[0033] Specifically, under the elastic force of the first spring 20, the pushing bar 19 always has a tendency to move away from the storage groove 6. In the initial state, the first guiding pin 24 is located inside the horizontal groove 21. During the movement of the conveying rod 3, it will drive the pushing bar 19 and the first guiding pin 24 to move. When the first guiding pin 24 moves from the horizontal groove 21 to the inside of the V-shaped groove 22, under the guiding action of the V-shaped groove 22, it can first move downward and then move upward to reset. During the downward movement, the first guiding pin 24 can drive the pushing bar 19 to move downward. During the process of the pushing bar 19 sliding along the surface of the wedge block 18, the drill bit 12 can be pushed out. During the upward movement, the first guiding pin 24 can drive the pushing bar 19 to move upward, so that the drill bit 12 retracts into the storage groove 6. By arranging multiple V-shaped grooves 22, under the guiding action, the drill bit 12 can intermittently extend, expanding the dispersion range, thereby promoting the growth of seeds. Until the first guiding pin 24 moves into the lower guiding groove 23, under the guiding of the lower guiding groove 23, it re-guides the pushing bar 19 to move downward, and the storage cylinder 7 is pushed out again. The pushed-out storage cylinder 7 can also increase the contact area between the bottom of the positioning column 1 and the soil, which is beneficial to improving the stability of the positioning column 1 and reducing the adverse effects of external factors on the stability of the positioning column 1.

[0034] As a further embodiment of the present invention, a chute 25 is formed at the bottom of the drill bit 12. The chute 25 is sleeved on the outside of the storage cylinder 7. A sliding cylinder 26 is fixed on the inner wall of the chute 25. The sliding cylinder 26 passes through the storage cylinder 7 and extends into the storage cylinder 7. A fixing plate 27 is fixed on the surface of the sliding cylinder 26. A first pulling spring 28 is fixed between the fixing plate 27 and the inner wall of the storage cylinder 7. A plurality of top plates 29 are slidably connected to the side wall of the fixing plate 27. A second guiding pin 30 is fixed on the side wall of the top plate 29. A guiding groove is formed on the inner wall of the discharge port 13. The guiding groove is composed of an inclined groove 31 and a straight groove 32. The second guiding pin 30 is inserted into the guiding groove.

[0035] Specifically, during the extension process of the drill bit 12, under the blocking action of the soil, it can push the sliding cylinder 26 and the fixed plate 27 to move inside the storage cylinder 7. The fixed plate 27 drives the pushing plate 29 to slide in the discharge port 13. The second guide pin 30 first slides in the inclined slot 31. Under the guiding action of the inclined slot 31 and the second guide pin 30, it can drive the pushing plate 29 to push the positioning film 14 outwards, promoting the separation of the seeds from the positioning film 14. And during the movement of the second guide pin 30 in the straight slot 32, it can continuously maintain the pushing action, enabling all seeds to be separated from the positioning film 14.

[0036] As a further embodiment of the present invention, a screw rod 33 is fixed on the top surface of the slider 17. The screw rod 33 is inserted inside the sliding cylinder 26. A threaded sleeve 34 is threadedly connected to the surface of the screw rod 33. The threaded sleeve 34 is unidirectionally rotatably connected to the bottom surface of the sliding cylinder 26.

[0037] Specifically, during the process of dispersing the seeds, in order to further expand the dispersion range of the seeds, the present invention is provided with a screw rod 33. When the drill bit 12 pushes the soil, since the push rod 16 is threadedly connected to the communication hole 10, the drill bit 12 can rotate. It is set that the drill bit 12 rotates forward at this time, while the screw rod 33 is fixed on the slider 17 and remains stationary. At this time, the drill bit 12 is rotatably connected to the threaded sleeve 34. Thus, during the extension process of the drill bit 12, under the blocking action of the threaded sleeve 34, the drill bit 12 will not contract, so that the soil can be better broken up. After the breaking up is completed, during the process of the drill bit 12 contracting into the storage groove 6 under the pulling action of the push rod 16, the drill bit 12 rotates in the reverse direction. Since the threaded sleeve 34 is unidirectionally rotatably connected to the sliding cylinder 26, at this time, the drill bit 12 can drive the sliding cylinder 26 and the threaded sleeve 34 to rotate synchronously. Under the threaded connection, the threaded sleeve 34 moves downward along the screw rod 33, thereby driving the sliding cylinder 26, the fixed plate 27, and the pushing plate 29 to move synchronously. The pushing plate 29 pushes the positioning film 14 to separate the seeds. Since the pitch on the surface of the screw rod 33 is smaller than the pitch on the surface of the sliding cylinder 26, the pushing plate 29 can drive the pushing plate 29 to descend a short distance during each contraction and reset process of the drill bit 12, so that only part of the seeds are pushed out for separation each time. Since the drill bit 12 is at different soil depths each time it extends, the seeds can be evenly dispersed in the soil at different heights, further expanding the dispersion range of the seeds. Thus, during the subsequent growth process of the seeds, they can better wind and combine with the positioning column 1.

[0038] As a further embodiment of the present invention, a plurality of brackets 35 are fixed on the inner wall of the push rod 16. A plug rod 36 is slidably inserted on the bracket 35. A limit plate 37 is fixed on the surface of the plug rod 36. A second pulling spring 38 is fixed between the limit plate 37 and the inner wall of the push rod 16. A damping block 39 is fixed on the surface of the bracket 35. The damping block 39 is in frictional contact with the surface of the plug rod 36. A thin rod 40 is fixed at the tail end of the plug rod 36. The cross-sectional dimension of the thin rod 40 is smaller than that of the damping block 39. A guiding surface is formed on the surface of the threaded sleeve 34. An inclined surface adapted to the guiding surface is formed at one end of the thin rod 40 close to the screw rod 33.

[0039] Specifically, a relatively large gap is provided between the plug rod 36 and the threaded sleeve 34. During the process of the threaded sleeve 34 moving down along the screw rod 33, it will gradually approach the plug rod 36. Until the last descent, the guiding surface on the side wall of the threaded sleeve 34 contacts the inclined surface at the end of the plug rod 36, and pushes the thin rod 40 to gradually approach the damping block 39, so that the plug rod 36 is separated from the damping block 39. And the cross-sectional dimension of the thin rod 40 is small and will not contact the damping block 39. Thus, after entering the soil subsequently, under the pulling action of the second pulling spring 38, the limit plate 37 drives the plug rod 36 to insert into the soil, which can increase the contact area between the positioning column 1 and the soil and provide more winding positions for the plant roots, further increasing the stability of the positioning column 1.

[0040] As a further embodiment of the present invention, a ventilation channel 41 communicating with the inside of the sliding cylinder 26 is formed in the inner wall of the plug rod 36, and ventilation holes 42 are formed in the side wall of the plug rod 36.

[0041] Specifically, when the plug rod 36 extends outwards, the outside air can smoothly enter the ventilation channel 41 from the inside of the push rod 16. During the process of air flow, due to the communication between the ventilation channel 41 and the ventilation holes 42, the air slowly overflows from the ventilation holes 42. These gases flowing out of the plug rod 36, relying on the unique structure and extension characteristics of the plug rod 36, can effectively expand the diffusion range in the surrounding space, so that the gases can be more evenly and widely distributed in the environment, thereby improving the efficiency and effect of gas diffusion, promoting plant growth, and enabling the plant roots to better wind and combine with the positioning column 1.

[0042] As a further embodiment of the present invention, the pressing-down assembly includes a vertical rod 43. The vertical rod 43 is rotatably connected to the top of the push plate 5. A connecting plate 44 is fixed on the inner wall of the positioning column 1. The vertical rod 43 is threadedly connected with the connecting plate 44. A first bevel gear 45 is sleeved and fixed on the surface of the vertical rod 43. A second bevel gear 46 is engaged with one side of the first bevel gear 45. A knob 47 is rotatably connected to the outer wall of the positioning column 1. The knob 47 is coaxially fixed with the second bevel gear 46.

[0043] Specifically, by rotating the knob 47, the knob 47 drives the second bevel gear 46 to rotate. The second bevel gear 46 drives the first bevel gear 45 and the vertical rod 43 to rotate. Since the vertical rod 43 is threadedly connected to the connecting plate 44, under the action of the threaded connection, the vertical rod 43 moves downward, driving the push plate 5 to move downward synchronously, and pushing a plurality of conveying rods 3 into the soil to complete the pushing function.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
