Description

Technical Field

[0001] This invention relates to the field of well site guardrail technology, and particularly to a snake-blocking device, a field well site guardrail, and its installation method. Background Technology

[0002] Oil and gas well stations are typically located in the wild or mountainous areas. Conventional fencing is used to surround these stations to prevent unauthorized personnel and large animals from entering. However, because mountainous areas have a high prevalence of snakes, especially venomous ones, conventional fencing, while effective against unauthorized personnel and large animals, is ineffective against snakes. Figure 1 , Figure 2 and Figure 16 As shown, the guardrail includes posts 11 and a net 12. Posts 11 are set on independent foundations 2. The net 12 is generally abutted against or slightly higher than the independent foundations 2. When pouring or burying the independent foundations 2, in order to ensure that the independent foundations 2 are at the same height to facilitate the subsequent installation of the guardrail, the top surface of the independent foundations 2 is generally slightly higher than the ground 3, resulting in a certain gap 4 between the bottom of the net 12 and the ground 3. Mountain snakes can easily enter the well station working area through the gap 4 at the bottom of the net 12. If the staff in the well station are not careful and are bitten by snakes, due to the distance from the hospital and the inconvenience of vehicles, the snake bite can easily lead to death.

[0003] For example, Chinese invention patent application CN113463970A discloses a splicing power fence for outdoor power equipment. This splicing power fence can be quickly assembled in the wild and serves as a warning to wild animals, preventing damage to power facilities by wild animals. However, there is a gap between the power grid and the ground, which cannot effectively prevent snakes from passing through. Summary of the Invention

[0004] The purpose of this invention is to address the problem that conventional field well station guardrails have gaps between the bottom and the ground, which cannot effectively prevent snakes from passing through, and to provide a snake-blocking device, a field well station guardrail, and its installation method.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A snake-blocking device includes a snake-blocking plate and barbed rollers. The snake-blocking plate includes a first bent plate and a second bent plate that are hinged to each other. The first bent plate is located above the second bent plate. The first bent plate and the second bent plate form a snake-blocking area. A plurality of barbed rollers are disposed in the snake-blocking area. The barbed rollers have an inner cavity inside. The outer surface of the barbed rollers has a plurality of through holes communicating with the inner cavity. The inner cavity is used to hold snake-repelling powder.

[0007] The present invention discloses a snake-blocking device, comprising a snake-blocking plate and barbed rollers. The snake-blocking plate includes a first bent plate and a second bent plate hinged together, with the first bent plate positioned above the second bent plate. The first and second bent plates form a snake-blocking area, thereby preventing snakes from passing through. Multiple barbed rollers are placed within the snake-blocking area to further enhance the snake-blocking effect and prevent snakes from remaining there. Furthermore, the hinged connection between the first and second bent plates allows the first bent plate to rotate and open around the hinge point, facilitating the replacement of the barbed rollers or the inspection of the snake-blocking area. When applied to conventional field well station fencing, the top of the first bent plate abuts against the guardrail and posts, while the bottom of the second bent plate is positioned below ground level. This allows the snake-blocking plate to cover the gap between the bottom of the field well station fencing and the ground. When a snake passes through this gap and enters the snake-blocking area of ​​the device, the snake-blocking device is blocked by the snake-blocking plate. The invention employs a barbed roller to prevent snakes from passing through, ensuring the snake-repelling device effectively prevents snakes from entering the well station's working area and avoiding snake injuries. Furthermore, the barbed roller has an internal cavity, and its outer surface has several through holes communicating with the internal cavity. The internal cavity is used to hold snake-repelling powder. When a snake enters the snake-repelling area and triggers the rotation of the barbed roller, the snake-repelling powder inside the inner cavity is released through the through holes on the outer surface of the barbed roller, achieving a snake-repelling effect. This snake-repelling device, when used in conjunction with conventional field well station guardrails, enables conventional field well station guardrails to have a snake-repelling effect without requiring the fabrication and installation of new guardrails, greatly saving on guardrail construction costs. Simultaneously, the snake-repelling device of this invention has a simple structure, strong adaptability, and can be applied to various guardrails without altering their original structure, enabling the guardrails to have a snake-repelling effect.

[0008] As a preferred embodiment of the present invention, it further includes partitions, which are spaced apart along the length of the snake-blocking plate within the snake-blocking area, and the barbed rollers are detachably installed between adjacent partitions. By providing partitions within the snake-blocking area of ​​the snake-blocking plate, it is convenient to install barbed rollers between the partitions. Furthermore, the detachable installation of barbed rollers between adjacent partitions facilitates the replacement of barbed rollers in the future.

[0009] As a preferred embodiment of the present invention, the barbed roller includes a cylindrical body and smooth shafts disposed at both ends of the cylindrical body. A U-shaped component is disposed on the side of the partition, and the smooth shafts are installed inside the U-shaped component. By installing the smooth shafts at both ends of the cylindrical body inside the U-shaped component on the side of the partition, the barbed roller can be detachably installed on the partition, facilitating future replacement of the barbed roller.

[0010] As a preferred embodiment of the present invention, rotation of at least one of the adjacent cylinders can drive rotation of the other cylinder.

[0011] As a preferred embodiment of the present invention, the first bending plate includes a top plate and an inclined plate connected to each other, the top plate is located above the inclined plate, and the end of the inclined plate away from the top plate is hinged to the second bending plate;

[0012] The second bending plate includes a base plate and a vertical plate connected to each other. The base plate is located below the vertical plate, and the end of the vertical plate away from the base plate is connected to the inclined plate.

[0013] This application also discloses a field well station guardrail, including a post, a protective net, a trench, and a snake-blocking device as described in this application. The end of the first bending plate away from the second bending plate abuts against both the post and the protective net, and the first bending plate is detachably connected to the post. The end of the second bending plate away from the first bending plate is located in the trench, and the second bending plate abuts against the bottom of the trench.

[0014] This invention discloses a field well site guardrail, comprising posts, a protective net, a trench, and a snake-blocking device as described in this application. The end of a first bent plate away from a second bent plate abuts against both the posts and the protective net, and the first bent plate is detachably connected to the posts. The end of the second bent plate away from the first bent plate is located within the trench, and the second bent plate abuts against the bottom of the trench. Because a trench is provided on the ground, and the second bent plate abuts against the bottom of the trench, a portion of the second bent plate can be installed below ground level. This allows the snake-blocking device to cover the gap between the bottom of the protective net and the ground, unlike the case where the second bent plate is in direct contact with the ground. In contrast, this design avoids the gap between the second bending plate and the ground caused by uneven ground, which could allow snakes to easily slip through. This effectively prevents snakes from passing through the bottom of the guardrail, giving the field well station guardrail of this invention a snake-blocking effect. It can effectively prevent snakes from entering the field well station. Furthermore, since the first bending plate is detachably connected to the post, when it is necessary to replace the barbed roller or inspect the snake-blocking area of ​​the guardrail, the connection between the first bending plate and the post can be loosened. Because the first and second bending plates are hinged together, it is easy to open the first bending plate, thereby facilitating the replacement of the barbed roller or the inspection of the snake-blocking area.

[0015] In a preferred embodiment of the present invention, the partition is connected to the second bent plate, and the end of the partition away from the second bent plate is connected to the column. The partition is connected to both the second bent plate and the column, ensuring the stability of the partition while also indirectly connecting the second bent plate and the column, thus increasing the stability of the second bent plate.

[0016] As a preferred embodiment of the present invention, the end of the top plate away from the inclined plate abuts against both the column and the protective net, and the top plate is detachably connected to the column. The bottom plate abuts against the bottom surface of the trench, and the bottom plate extends toward the protective net. The end of the vertical plate away from the bottom plate extends to the outside of the trench.

[0017] As a preferred embodiment of the present invention, it further includes an L-shaped plate, one end of which is bolted to the column and the other end of which is bolted to the top plate.

[0018] This application also discloses a method for installing a field well station guardrail, including the field well station guardrail described in this invention, and further including the following steps:

[0019] S1: Excavate a trench on the side of the guardrail closest to the well station;

[0020] S2: Install the second bent plate in the trench so that the second bent plate abuts against the bottom of the trench, and then install the partition plate;

[0021] S3: Install a plurality of the barbed rollers between adjacent partitions;

[0022] S4: Install the first bending plate, hinge the first bending plate to the second bending plate, and make the first bending plate abut against both the column and the protective net. Then, make a detachable connection between the first bending plate and the column.

[0023] The present invention discloses a method for installing a field well station guardrail. First, a trench is dug on the ground on the side of the guardrail closest to the well station. Then, a second bent plate and a partition are installed. Next, a barbed roller and a first bent plate are installed. This allows the snake-blocking device to cover the gap between the bottom of the guardrail and the ground, thereby preventing snakes from passing through the bottom of the guardrail. This gives the field well station guardrail of the present invention a snake-blocking effect, effectively preventing snakes from entering the field well station.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The snake-blocking device of the present invention includes a snake-blocking plate and barbed rollers. The snake-blocking plate includes a first bent plate and a second bent plate hinged together. The first bent plate is located above the second bent plate, and the first and second bent plates form a snake-blocking area, thereby preventing snakes from passing through. Multiple barbed rollers are placed in the snake-blocking area to further increase the snake-blocking effect and prevent snakes from staying in the snake-blocking area. Since the first and second bent plates are hinged, the first bent plate can be easily rotated and opened around the hinge point, facilitating the replacement of the barbed rollers or the inspection of the snake-blocking area. When applied to conventional field well station guardrails, the top of the first bent plate abuts against the guardrail and the post, and the bottom of the second bent plate is placed below the ground, so that the snake-blocking plate covers the gap between the bottom of the field well station guardrail and the ground. When a snake passes through the gap between the bottom of the guardrail and the ground and enters the snake-blocking area of ​​the snake-blocking device, the snake-blocking device prevents snakes from passing through. The device uses a plate and barbed rollers to prevent snakes from passing through, ensuring its effectiveness in blocking snakes and preventing them from entering the well site's working area, thus avoiding snake injuries. Furthermore, the barbed rollers have an internal cavity, and their outer surface has several through holes communicating with this cavity. The cavity is used to hold snake-repelling powder. When a snake enters the blocking area and triggers the rotation of the barbed rollers, the powder inside the cavity is released through the through holes on the outer surface, effectively repelling the snake. This snake-blocking device, when used in conjunction with conventional field well site fencing, enables conventional fencing to have a snake-blocking effect without requiring the fabrication and installation of new fencing, significantly reducing construction costs. Moreover, this snake-blocking device has a simple structure, strong adaptability, and can be used on various fencing types without altering the original fencing structure, thus providing a snake-blocking effect.

[0026] 2. The field well site guardrail of the present invention includes posts, a protective net, a trench, and a snake-blocking device as described in this application. The end of the first bent plate away from the second bent plate abuts against both the posts and the protective net, and the first bent plate is detachably connected to the posts. The end of the second bent plate away from the first bent plate is located in the trench, and the second bent plate abuts against the bottom of the trench. Because a trench is set on the ground and the second bent plate abuts against the bottom of the trench, it ensures that part of the second bent plate can be installed below ground level, thereby allowing the snake-blocking device to cover the gap between the bottom of the protective net and the ground, unlike situations where the second bent plate is in direct contact with the ground. Compared to other methods, this design avoids the gap between the second bending plate and the ground caused by uneven ground, which could allow snakes to easily squeeze through. This effectively prevents snakes from passing through the bottom of the guardrail, giving the field well station guardrail of this invention a snake-blocking effect. It can effectively prevent snakes from entering the field well station. Furthermore, since the first bending plate is detachably connected to the post, when it is necessary to replace the barbed roller or inspect the snake-blocking area of ​​the guardrail, the connection between the first bending plate and the post can be loosened. Since the first and second bending plates are hinged together, it is easy to open the first bending plate, thereby facilitating the replacement of the barbed roller or the inspection of the snake-blocking area.

[0027] 3. The installation method of the field well station guardrail of the present invention involves first digging a trench in the ground on the side of the guardrail close to the well station, then installing the second bending plate and partition, and then installing the barbed roller and the first bending plate. This allows the snake-blocking device to cover the gap between the bottom of the guardrail and the ground, thereby preventing snakes from passing through the bottom of the guardrail. This gives the field well station guardrail of the present invention a snake-blocking effect, effectively preventing snakes from entering the field well station. Attached Figure Description

Detailed Implementation

[0045] The present invention will be further described in detail below with reference to embodiments and specific implementation methods. However, this should not be construed as limiting the scope of the above-described subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0046] Example 1

[0047] like Figures 3-7As shown, the snake-blocking device described in this embodiment includes a snake-blocking plate 5 and barbed rollers 6. The snake-blocking plate 5 includes a first bent plate 51 and a second bent plate 52 that are hinged to each other. The first bent plate 51 is located above the second bent plate 52. The first bent plate 51 and the second bent plate 52 form a snake-blocking area 54. A plurality of barbed rollers 6 are disposed in the snake-blocking area 54. The barbed rollers 6 have an inner cavity inside. The outer surface of the barbed rollers 6 has a plurality of through holes that communicate with the inner cavity. The inner cavity is used to hold snake-repelling powder.

[0048] The snake-blocking device described in this embodiment forms a snake-blocking area 54 through a first bending plate 51 and a second bending plate 52, thereby preventing snakes from passing through. Multiple barbed rollers 6 are placed within the snake-blocking area 54 to further enhance the snake-blocking effect and prevent snakes from remaining within it. Since the first bending plate 51 and the second bending plate 52 are hinged, the first bending plate 51 can be easily rotated around the hinge point to open, facilitating the replacement of the barbed rollers 6 or the inspection of the snake-blocking area 54. When applied to conventional field well station guardrails, the top of the first bending plate 51 abuts against the guardrail 12 and the post 11, and the bottom of the second bending plate 52 is positioned below the ground 3, thus covering the gap 4 between the bottom of the field well station guardrail and the ground 3. When a snake passes through the gap 4 between the bottom of the guardrail and the ground 3, it enters the snake-blocking area 54 of the snake-blocking device. The snake-blocking device uses the snake-blocking plate 5 and the barbed rollers 6 to block the snake. This invention prevents snakes from entering the well site working area, thus avoiding snake injuries. Furthermore, the barbed roller 6 has an internal cavity, and its outer surface has several through holes communicating with the internal cavity. The internal cavity is used to hold snake repellent powder. When a snake enters the snake-blocking area 54 and triggers the rotation of the barbed roller 6, the snake repellent powder inside the internal cavity is released through the through holes on the outer surface of the barbed roller 6, achieving a snake-repelling effect. This snake-blocking device, when used in conjunction with conventional field well site guardrails, enables conventional field well site guardrails to have a snake-blocking effect without requiring the fabrication and installation of new guardrails, greatly saving on guardrail construction costs. Simultaneously, this snake-blocking device has a simple structure, strong adaptability, and can be used on various guardrails without altering their original structure, enabling the guardrails to have a snake-blocking effect.

[0049] A preferred method, such as Figure 6 , Figure 9 As shown, it also includes partitions 7, which are spaced apart along the length of the snake-blocking plate 5 within the snake-blocking area 54. Barbed rollers 6 are detachably installed between adjacent partitions 7, as shown. Figure 10 By setting a partition 7 in the snake-blocking area 54 of the snake-blocking plate 5, it is convenient to install the barbed roller 6 between the partitions 7. Furthermore, the barbed roller 6 can be detachably installed between adjacent partitions 7, which facilitates the replacement of the barbed roller 6 later.

[0050] A preferred method, such as Figure 12 As shown, the barbed roller 6 includes a cylinder body 61 and smooth shafts 62 disposed at both ends of the cylinder body 61. Barbed wire is wound around the cylinder body 61. A U-shaped component 20 is disposed on the side of the partition 7. The smooth shafts 62 are installed inside the U-shaped component 20. By installing the smooth shafts 62 at both ends of the cylinder body 61 inside the U-shaped component 20 on the side of the partition 7, the barbed roller 6 can be detachably installed on the partition 7, facilitating future replacement of the barbed roller 6. As shown in Figure 10, the U-shaped component 20 can be assembled and welded from three steel bars. The inside of the U-shaped component 20 needs to be polished smooth so that after the smooth shafts 62 of the barbed roller 6 are installed inside the U-shaped component 20, the smooth shafts 62 slide in contact with the inside of the U-shaped component 20. When a snake touches the barbed roller 6, the smooth shafts 62 of the barbed roller 6 can rotate inside the U-shaped component 20, thereby causing the barbed roller 6 to rotate when touched by a snake, achieving a better snake-repelling effect.

[0051] In a preferred embodiment, rotation of at least one adjacent cylinder 61 can drive rotation of the other cylinder 61, such as... Figure 13 As shown, a transmission belt 30 is provided between adjacent cylinders 61. When a snake touches a barbed roller 6 and it rotates, the barbed roller 6 drives the adjacent barbed roller 6 to rotate together through the transmission belt 30, thereby enabling multiple barbed rollers 6 to spray snake repellent powder outward, achieving a better snake repellent effect. The transmission belt 30 can be selected as a toothed transmission belt, and a circular toothed plate matching the transmission belt 30 is provided on the cylinder 61. The transmission belt 30 is sleeved on the toothed plate to realize transmission.

[0052] In the above scheme, the transmission belt 30 can also be replaced with a gear mechanism.

[0053] In a preferred embodiment, the partition 7 is preferably a steel plate, and the U-shaped parts 20 are welded to the side of the partition 7. The number of U-shaped parts 20 and their positions on the partition 7 are determined by the required number and installation position of the barbed rollers 6.

[0054] A preferred method, such as Figure 7 As shown, the first bent plate 51 includes a top plate 511 and an inclined plate 512 connected to each other. The top plate 511 is located above the inclined plate 512, and the end of the inclined plate 512 away from the top plate 511 is hinged to the second bent plate 52. The second bent plate 52 includes a bottom plate 521 and a vertical plate 522 connected to each other. The bottom plate 521 is located below the vertical plate 522, and the end of the vertical plate 522 away from the bottom plate 521 is connected to the inclined plate 512.

[0055] A preferred method, such as Figure 7 , Figure 14As shown, the snake-blocking plate 5 also includes a hinge shaft 53, which is located between the first bent plate 51 and the second bent plate 52. The first bent plate 51 and the second bent plate 52 are hinged together by the hinge shaft 53, so that the first bent plate 51 can be rotated and opened around the hinge shaft 53, which facilitates the subsequent replacement of the barbed roller 6 or the inspection of the snake-blocking area 54. The end of the inclined plate 512 away from the top plate 511 is connected to the hinge shaft 53, and the end of the vertical plate 522 away from the bottom plate 521 is connected to the hinge shaft 53. That is, the inclined plate 512 and the vertical plate 522 are hinged together by the hinge shaft 53.

[0056] In a preferred embodiment, the top plate 511, the inclined plate 512, the bottom plate 521, and the vertical plate 522 are preferably steel plates, wherein the first bending plate 51 can be made of steel plates spliced ​​together or integrally molded, and the second bending plate 52 can be made of steel plates spliced ​​together or integrally molded.

[0057] In a preferred manner, the snake repellent powder can be realgar powder or sulfur powder.

[0058] In a preferred embodiment, the cylinder body 61 has an inner cavity, and the outer surface of the cylinder body 61 has several through holes that communicate with the inner cavity. The inner cavity is used to hold realgar powder. When a snake touches the barbed roller 6 and the barbed roller 6 rotates, the realgar powder inside the inner cavity of the cylinder body 61 is released from the through holes, achieving a better snake-repelling effect.

[0059] Example 2

[0060] Based on Example 1, such as Figures 3-6 As shown in the figure, the field well station guardrail described in this embodiment includes a post 11, a protective net 12, a trench 8, and a snake-blocking device as described in Embodiment 1. The end of the first bending plate 51 away from the second bending plate 52 abuts against both the post 11 and the protective net 12, and the first bending plate 51 is detachably connected to the post 11. The end of the second bending plate 52 away from the first bending plate 51 is located in the trench 8, and the second bending plate 52 abuts against the bottom of the trench 8.

[0061] This embodiment of a field well station guardrail includes a post 11, a protective net 12, a trench 8, and a snake-blocking device as described in Embodiment 1. The end of the first bent plate 51 furthest from the second bent plate 52 abuts against both the post 11 and the protective net 12, and the first bent plate 51 is detachably connected to the post 11. The end of the second bent plate 52 furthest from the first bent plate 51 is located within the trench 8, and the second bent plate 52 abuts against the bottom of the trench 8. Because the trench 8 is set on the ground 3, and the second bent plate 52 abuts against the bottom of the trench 8, it ensures that part of the second bent plate 52 can be installed below the ground 3, thereby allowing the snake-blocking device to cover the gap between the bottom of the protective net 12 and the ground 3, and to directly connect the second bent plate 52 to the ground 3. Compared to the contact situation, this avoids the gap between the second bending plate 52 and the ground 3 caused by the unevenness of the ground 3, which would allow snakes to easily crawl through. This effectively prevents snakes from passing through the bottom of the guardrail 12, giving the field well station guardrail described in this embodiment a snake-blocking effect. It can effectively play a snake-prevention role in field well stations. Furthermore, since the first bending plate 51 is detachably connected to the post 11, when it is necessary to replace the barbed roller 6 or to inspect the snake-blocking area 54 of the snake-blocking plate 5, the connection between the first bending plate 51 and the post 11 can be loosened. Since the first bending plate 51 and the second bending plate 52 are hinged to each other, it is easy to open the first bending plate 51, thereby facilitating the replacement of the barbed roller 6 or the inspection of the snake-blocking area 54.

[0062] A preferred method, such as 9. Figures 11-12 As shown, the partition 7 is connected to the second bent plate 52, and the end of the partition 7 away from the second bent plate 52 is connected to the column 11. The partition 7 is connected to the second bent plate 52 and the column 11 respectively. While ensuring the stability of the partition 7, the partition 7 also indirectly connects the second bent plate 52 and the column 11, increasing the stability of the second bent plate 52. The partition 7 and the second bent plate 52 can be connected by welding, and the partition 7 and the column 11 can be connected by welding.

[0063] A preferred method, such as Figure 6As shown, the top plate 511, at the end away from the inclined plate 512, abuts against both the post 11 and the protective net 12, and the top plate 511 is detachably connected to the post 11. The bottom plate 521 abuts against the bottom of the trench 8, and the bottom plate 521 extends towards the protective net 12. The end of the vertical plate 522 away from the bottom plate 521 extends to the outside of the trench 8. By abutting the top plate 511 against both the post 11 and the protective net 12, and abutting the bottom plate 521 against the bottom surface of the trench 8, it is ensured that the snake-blocking plate 5 can completely cover the gap 4 between the bottom of the field well station fence and the ground 3, ensuring that the field well station fence described in this embodiment can play its snake-blocking effect. Furthermore, since the top plate 511 is detachably connected to the post 11, when it is necessary to replace the barbed roller 6 or to carry out snake-blocking work in the snake-blocking area 54, the snake-blocking plate 5 can be easily replaced. During inspection, the connection between the top plate 511 and the column 11 is loosened. Since the first bending plate 51 and the second bending plate 52 are hinged to each other, it is easy to open the first bending plate 51, which facilitates the replacement of the barbed roller 6 or the inspection of the snake-blocking area 54. Furthermore, the bottom plate 521 extends towards the protective net 12. With the bottom plate 521 abutting against the bottom of the trench 8, the bottom plate 521 extends towards the protective net 12, which makes the bottom plate 521 fit more tightly with the bottom of the trench 8, preventing snakes from crawling out between the bottom plate 521 and the bottom of the trench 8. Furthermore, the end of the vertical plate 522 away from the bottom plate 521 extends to the outside of the trench 8, which facilitates the hinge of the vertical plates 522 to each other, and thus facilitates the hinge of the second bending plate 52 to the first bending plate 51.

[0064] A preferred method, such as Figure 8 As shown, it also includes an L-shaped plate 9, one end of which is bolted to the column 11, and the other end of which is bolted to the top plate 511. By setting the L-shaped plate 9, the column 11 and the top plate 511 can be detachably connected, and the top plate 511 can also be fixed to the column 11 by the L-shaped plate 9.

[0065] In a preferred embodiment, a plurality of L-shaped plates 9 are spaced apart along the length of the snake-blocking plate 5, and the L-shaped plates 9 are preferably thin steel plates.

[0066] A preferred method, such as Figure 4 , Figure 14 As shown, the first bent plate 51 of the snake-blocking plate 5 has an arc-shaped edge 513 at the point where it abuts against the post 11. The arc-shaped edge 513 matches the post 11, thus ensuring that the first bent plate 51 can still abut against the post 11 after it abuts against the guardrail 12. Then, the first bent plate 51 and the post 11 are connected together by the L-shaped plate 9, so that the snake-blocking plate 5 is tightly connected to the guardrail.

[0067] A preferred method, such as Figure 15As shown, a trench 8 is excavated on the side of the guardrail closest to the well site. The trench 8 is close to the guardrail, and the bottom surface of the trench 8 is horizontal and below the ground surface 3. This ensures that the bottom plate 521 of the second bending plate 52 can be below the ground surface after it comes into contact with the bottom surface of the trench 8.

[0068] Example 3

[0069] Based on Example 2, the installation method of a field well station guardrail described in this example includes a field well station guardrail as described in Example 2, and further includes the following steps:

[0070] S1: As Figure 15 As shown, a trench 8 was excavated on the side of the guardrail closest to the well site;

[0071] S2: Install a second bent plate 52 inside the trench 8 so that the second bent plate 52 abuts against the bottom of the trench 8, and then install a partition 7, wherein the bottom plate 521 abuts against the bottom of the trench 8 and the bottom plate 521 extends toward the protective net 12, and the end of the vertical plate 522 away from the bottom plate 521 extends to the outside of the trench 8.

[0072] S3: Install multiple barbed rollers 6 between adjacent partitions 7, wherein the smooth shaft 62 of the barbed rollers 6 is installed inside the U-shaped piece 20 on the side of the partition 7;

[0073] S4: Install the first bending plate 51, hinge the first bending plate 51 to the second bending plate 52, and make the first bending plate 51 abut against the column 11 and the guardrail 12. Then, make a detachable connection between the first bending plate 51 and the column 11. The inclined plate 512 of the first bending plate 51 is hinged to the vertical plate 522 of the second bending plate 52. The top plate 511 of the first bending plate 51 abuts against the column 11 and the guardrail 12, and the top plate 511 is detachably connected to the column 11.

[0074] The installation method of the field well station guardrail described in this embodiment involves first digging a trench 8 on the ground on the side of the guardrail closest to the well station, then installing the second bending plate 52 and the partition 7, and then installing the barbed roller 6 and the first bending plate 51. This allows the snake-blocking device to cover the gap 4 between the bottom of the guardrail 12 and the ground 3, thereby preventing snakes from passing through the bottom of the guardrail. This gives the field well station guardrail described in this embodiment a snake-blocking effect, effectively preventing snakes from entering the field well station.

[0075] In a preferred embodiment, in step S3, the gap between two adjacent barbed rollers 6 is less than or equal to 2cm to 3cm, and the gap between the barbed roller 6 closest to the ground 3 and the ground 3 is less than or equal to 2cm to 3cm. By limiting the gap between two adjacent barbed rollers 6 and the gap between the barbed roller 6 closest to the ground 3 and the ground 3, it is ensured that snakes will touch the barbed rollers 6 when they enter the snake-blocking area 54, thereby achieving the purpose of repelling snakes.

[0076] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
