DETAILED DESCRIPTION

[0040] This section will describe in detail the specific embodiments of the present application. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0043] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0044] In the related technology, when water conservancy projects such as levees and dams suffer from seepage damage such as pipe bursts, anti-filtration wells are usually used for rescue. Since the materials required for the anti-filtration wells need to be transported to the site by vehicles only after the dangerous situation occurs, manual transportation is still required when there are no roads. Construction (piling sandbags and dumping sand and gravel into the well) can only be carried out after the materials are transported to the site. In other words, the entire rescue process cannot be carried out in advance, and manpower and material resources can only be urgently organized after the dangerous situation occurs, resulting in a slow rescue speed and difficulty in achieving rapid rescue, thereby causing large or even irreparable damage to the water conservancy project.

[0045] To this end, the embodiment of the present application provides a chain anti-filter 100 and a method for protecting against penetration damage using the chain anti-filter 100 to reduce the steps of operation at the accident site, increase the speed of rescue, and achieve rapid rescue.

[0046] For example, Figures 1 to 3 Some chain type anti-filter 100 embodiments provided by the present application are shown. Figure 4 A flow chart showing some embodiments of the method for protecting against penetration damage provided by the present application by operating the chain-type anti-filter 100 is shown.

[0047] Reference Figure 4 , combined with Figures 1 to 3 , the protection method against penetration damage can include the following steps:

[0048] S110, providing a movable lock buckle 11 and a plurality of chain mesh units 12, wherein the chain mesh unit 12 comprises a plurality of mutually connected ring buckle structures.

[0049] By pre-connecting multiple ring structures, multiple chain net units 12 are assembled in advance, so that the materials required for rescue can be prepared in advance. The chain net units 12 can be prepared in advance before the risk of penetration and damage occurs, so as to reduce the operation steps at the accident site.

[0050] In some embodiments, the plurality of chain network units 12 include at least a first chain network unit 12 and a second chain network unit 12, the first chain network unit 12 and the second chain network unit 12 each include a first chain 121 and a second chain 122, the number of the movable lock buckles 11 is at least two, at least one of the movable lock buckles 11 is connected to the first chain 121 of the first chain network unit 12 and the first chain 121 of the second chain network unit 12, and at least another movable lock buckle 11 is connected to the second chain 122 of the first chain network unit 12 and the second chain 122 of the second chain network unit 12.

[0051] Thus, two adjacent chain mesh units 12 are connected via a plurality of movable locks 11 to increase the connection points, which is beneficial to improving the structural reliability of the chain mesh 10 formed in subsequent steps.

[0052] Please combine Figure 3 , Figures 5 to 7 Optionally, the first chain 121 and the second chain 122 are connected along a first direction (i.e. Figure 3 and Figure 5 The first chain 121 and the second chain 122 are arranged at intervals, each of which includes a first loop 1201, a second loop 1202 and a third loop 1203, and the chain mesh unit 12 also includes a first loop 123 and a second loop 124, that is, the plurality of loop structures at least include a first loop 1201, a second loop 1202, a third loop 1203, a first loop 123 and a second loop 124. The above step S110 also includes a preparation process of the chain mesh unit 12, that is, the above step S110 includes the following steps S111-S114:

[0053] S111, sequentially connect the first link 1201 of the first chain 121 and the second link 1202 of the first chain 121 along the second direction (i.e. Figure 3 and Figure 5 The first link 1201 of the second chain 122 and the second link 1202 of the second chain 122 are stacked up and down in an offset manner along the second direction in sequence.

[0054] S112, the first link 1201 of the first chain 121, the second link 1202 of the first chain 121, the first link 1201 of the second chain 122, and the second link 1202 of the second chain 122 are simultaneously fastened and connected through the first link 123.

[0055] Optionally, the first chain buckle 123 and the second chain buckle 124 are both provided with openings, and the above step S112 includes the following steps S1121-S1122:

[0056] S1121, pass the first chain buckle 123 through the opening, through the first loop buckle 1201 of the first chain 121, the second loop buckle 1202 of the first chain 121, the first loop buckle 1201 of the second chain 122, and the second loop buckle 1202 of the second chain 122.

[0057] S1122, pressing the opening of the first chain buckle 123 closed.

[0058] Thereby, the five ring-buckle structures can be locked together, so as to ensure the connection reliability between the multiple ring-buckle structures.

[0059] S113, stacking the third loop 1203 of the first chain 121 and the second loop 1202 of the first chain 121 in an up-and-down manner along the second direction, and stacking the third loop 1203 of the second chain 122 and the second loop 1202 of the second chain 122 in an up-and-down manner along the second direction.

[0060] S114, the second link 1202 of the first chain 121, the third link 1203 of the first chain 121, the second link 1202 of the second chain 122, and the third link 1203 of the second chain 122 are simultaneously fastened and connected through the second link 124.

[0061] In this way, the first chain 121 and the second chain 122 are connected by the first chain buckle 123 and the second chain buckle 124 so that a plurality of buckle structures are connected to form the chain network unit 12 .

[0062] Optionally, the above step S114 is similar to the above step S112. Specifically, the above step S114 includes the following steps S1141-S1142:

[0063] S1141, pass the second chain buckle 124 through the opening, respectively, through the second buckle 1202 of the first chain 121, the third buckle 1203 of the first chain 121, the second buckle 1202 of the second chain 122, and the third buckle 1203 of the second chain 122.

[0064] S1142, pressing the opening of the second chain buckle 124 closed.

[0065] Thus, a chain mesh unit 12 is formed in which a plurality of loop structures are locked and connected to each other, which helps to ensure the connection reliability between the plurality of loop structures, thereby improving the structural reliability of the chain mesh unit 12.

[0066] Optionally, the method for pressing and closing the openings of the first chain buckle 123 and the second chain buckle 124 can be manual pressing, or pressing with the help of mechanical tools (such as pliers or hammers, etc.), or pressing by mechanical pressure. The specific setting can be made according to actual needs and is not limited here.

[0067] It should be noted that, since the first ring buckle 1201, the second ring buckle 1202, the third ring buckle 1203, the first chain buckle 123 and the second chain buckle 124 are all ring buckle structures, the shape and structure of each ring buckle structure can be the same or substantially the same, so as to facilitate material selection and assembly operations. At this time, since the first ring buckle 1201, the second ring buckle 1202, and the third ring buckle 1203 also have openings, the openings of the first ring buckle 1201, the second ring buckle 1202, and the third ring buckle 1203 can be pressed before, after, or during step S110.

[0068] In other embodiments, the structures of the first ring buckle 1201, the second ring buckle 1202, and the third ring buckle 1203 are different from the structures of the first chain buckle 123 and the second chain buckle 124. The first ring buckle 1201, the second ring buckle 1202, and the third ring buckle 1203 do not have openings, which can help simplify the assembly steps of the chain network unit 12.

[0069] In some embodiments, the first direction and the second direction may be perpendicular to each other, so that the shape of the chain mesh unit 12 is more regular, which is beneficial to avoid structural interference between two adjacent chains.

[0070] It can be understood that in other embodiments, the first direction and the second direction may form an acute angle or an obtuse angle.

[0071] It should be noted that the area of ​​the chain net unit 12 can be achieved by controlling the length of the first chain 121 and the second chain 122 along the second direction, the number of chains, etc. according to actual needs (for example, the size of the seepage outlet of the infiltration damage (hereinafter referred to as the seepage outlet 200)), so as to reduce the construction steps and work content at the accident site while making the chain net unit 12 more suitable for handling and movement, thereby improving the portability of the chain net unit 12 and facilitating the assembly of the chain anti-filter 100.

[0072] For example, in other embodiments, the first chain 121 and the second chain 122 may further include a fourth loop, a fifth loop, and a plurality of loops stacked in sequence along the first direction, and the chain mesh unit 12 also correspondingly includes a third loop, a fourth loop, and a plurality of loops arranged in sequence along the first direction, and the loops of the first chain 121 and the second chain 122 are buckled and connected by the loops through the loops to increase the length of the first chain 121 and the second chain 122 along the second direction, thereby assembling and expanding the area of ​​the chain mesh unit 12. The chain mesh unit 12 may also include a third chain, a fourth chain, and a plurality of chains spaced apart along the second direction, the third chain is connected to the second chain 122 by the loops, and the plurality of chains are connected by the loops, thereby increasing the width of the chain mesh unit 12 along the first direction, thereby expanding the area of ​​the chain mesh unit 12.

[0073] S120, connecting two adjacent chain network units 12 through the movable lock buckle 11 to form a chain network 10.

[0074] Optionally, the movable lock buckle 11 can be a deformable lock buckle with an opening, for example, a ring buckle, an S-shaped lock buckle or a U-shaped lock buckle with double-ended openings, etc. After the movable lock buckle 11 is connected to two adjacent chain mesh units 12, the opening is pressed closed to achieve a quick lock connection, so as to shorten the time spent on connecting the movable lock buckle 11 and further improve the rescue efficiency.

[0075] It can be understood that in other embodiments, the movable lock buckle 11 can also be a clamp or a U-shaped pipe clamp, etc.

[0076] Optionally, the material of the ring structure can be any one of iron, copper or stainless steel, or other metal materials with high density. This ensures that the chain type filter screen 100 has sufficient weight to facilitate the chain type filter screen 100 to remain stable relative to the seepage port 200, and avoid the situation where the water flow or particles emerging from the seepage port 200 push the chain type filter screen 100 to move, thereby ensuring the filter effect on the seepage port 200.

[0077] Optionally, the aperture of the ring structure can be 5mm-10mm, for example, 5mm, 6mm, 7mm, 8mm or 9mm, so as to intercept fine particles carried away by the water flow caused by infiltration. The specific setting can be based on actual needs and is not limited here.

[0078] Optionally, the diameter of the ring structure may be 1 mm-2 mm, for example, 1 mm, 1.2 mm, 1.5 mm or 1.8 mm, etc., so as to ensure the strength of the ring structure and thus ensure the structural reliability of the chain-type reverse filter 100.

[0079] Optionally, the size of the chain net 10 can be achieved according to actual needs (such as the size of the seepage port 200, etc.) by controlling the number of chain net units 12 and the size of each chain net unit 12 and the movable lock buckle 11. When the shape of the chain net 10 is rectangular or quadrilateral, the length of the chain net 10 is 5 to 25 times the diameter of the seepage port 200, and the width of the chain net 10 is 5 to 25 times the diameter of the seepage port 200, for example, 10 times, 15 times or 20 times. When the shape of the chain net 10 is circular, the diameter of the chain net 10 is 5 to 25 times the diameter of the seepage port 200, for example, 10 times, 15 times or 20 times. In this way, it can be ensured that the chain net 10 has enough margin to fit the terrain and completely cover the seepage port 200, and the chain net 10 can also completely cover the seepage port 200 when it is slightly misaligned or offset.

[0080] Taking the shape of the chain net 10 as a rectangle, and the length and width of the chain net 10 being 20 times the diameter of the seepage port 200 as an example, when the diameter of the seepage port 200 is less than 5 cm, the size specification (length multiplied by width) of the chain net 10 can be 1m×1m; when the diameter of the pipe seepage port 200 is 5cm-10cm, the size of the chain net 10 can be 1.5m×1.5m; when the diameter of the seepage port 200 is greater than 10cm, a chain net 10 of 2m×2m or larger size can be selected, depending on the actual situation and is not limited here.

[0081] S130 , stacking a plurality of the chain nets 10 in sequence and staggeredly covering the seepage opening 200 of the infiltration damage to form a chain type reverse filter net 100 .

[0082] In this way, two adjacent chain net units 12 are connected to form a chain net 10 through the movable lock buckle 11, and then multiple chain nets 10 are stacked in sequence and staggered to cover the seepage port 200 of infiltration damage, so that the chain type reverse filter 100 has a sufficiently small aperture to eliminate water potential and achieve the purpose of emitting water without emitting sand (i.e. particles), thereby realizing reverse filtration of the seepage port 200, and the overall rescue operation is simple, which can help to improve the speed of rescue. At the same time, since the multiple ring buckle structures of the chain net unit 12 can be connected in advance, the chain net unit 12 can be prepared in advance before the infiltration damage danger occurs, so that the materials required for rescue can be prepared in advance, and the chain net unit 12 and the movable lock buckle 11 can be transported to the accident site for connection after the danger occurs, or the chain net 10 can be transported to the accident site after the preparation is completed, so as to reduce the operation steps at the accident site, thereby effectively improving the rescue speed and realizing rapid rescue.

[0083] In addition, since the chain-type anti-filter screen 100 has the ability to deform in both the first direction and the second direction, it can automatically conform to the terrain to adapt to uneven terrain conditions, which is beneficial to improving the scope of application of the chain-type anti-filter screen 100 and the anti-filtration effect on the seepage port 200. At the same time, the chain-type anti-filter screen 100 relies on its own gravity to cover and fix above the seepage port 200, which can facilitate the installation and disassembly of the chain-type anti-filter screen 100 and resist the thrust of water flow and particles on the chain-type anti-filter screen 100, so as to ensure that the chain-type anti-filter screen 100 covers the seepage port 200 to filter the water flow emerging from the seepage port 200.

[0084] Optionally, the above step S130 further includes the following steps S131-S132:

[0085] S131 , stacking the chain net 10 layer by layer on the seepage opening 200 damaged by penetration, wherein the chain net 10 covers the seepage opening 200 .

[0086] S132. When the water flowing out of the seepage port 200 does not carry any particles and the water flow speed slows down, stop stacking the chain net 10 onto the seepage port 200.

[0087] Thus, the chain type reverse filter 100 can ensure the reverse filtering effect on the seepage port 200, so as to intercept fine particles while ensuring that the water flow of the seepage port 200 can pass through. At the same time, it can also save invalid operation steps, save manpower and operation time, and thus improve the rescue efficiency.

[0088] Optionally, in some embodiments, the plurality of chain nets 10 include at least a first chain 121 net and a second chain 122 net 10 stacked and staggered on the seepage port 200, and the aperture of the loop structure of the first chain 121 net is different from the aperture of the loop structure of the second chain 122 net 10.

[0089] In this way, by stacking and staggeredly covering the seepage port 200 with two chain nets 10 with different apertures, the aperture of the chain anti-filter 100 can be further reduced, so as to intercept fine particles of different sizes emerging through the seepage port 200, improve the anti-filtration and drainage effect of the chain anti-filter 100, and thus improve the protective effect of the chain anti-filter 100 on the seepage port 200.

[0090] For example, Figure 8 A flow chart showing some other embodiments of the method for protecting against penetration damage provided by the present application by operating the chain-type anti-filter 100 is shown.

[0091] Please refer to Figure 8 , combined with Figures 1 to 3 , the protection method against penetration damage can include the following steps:

[0092] S210, providing a movable lock buckle 11 and a plurality of chain mesh units 12, wherein the chain mesh unit 12 comprises a plurality of mutually connected ring buckle structures.

[0093] S220, transporting the movable lock buckle 11 and the chain mesh unit 12 to the site of the infiltration damage accident.

[0094] In this way, the movable lock buckle 11 and the chain net unit 12 are transported to the accident site before being assembled to form the chain net 10. The small area and low weight of the movable lock buckle 11 and the chain net unit 12 can be utilized to facilitate the material transportation of the chain filter 100, save transportation costs, and prevent the chain net 10 from getting knotted during transportation.

[0095] S230, connecting two adjacent chain network units 12 through the movable lock buckle 11 to form a chain network 10.

[0096] By assembling the chain net 10 at the site of the infiltration damage accident, the area of ​​the chain net 10 can be adjusted and controlled according to the site conditions (such as the size of the seepage port 200, etc.), so as to improve the size matching between the chain filter net 100 and the seepage port 200, thereby improving the anti-filtration effect of the chain filter net 100 on the seepage port 200.

[0097] It can be understood that in some other embodiments, there is no particular order between step S220 and step S230, that is, step S220 can also be performed after step S230.

[0098] S240 , stacking a plurality of the chain nets 10 in sequence and staggeredly covering the seepage opening 200 of the infiltration damage to form a chain type reverse filter net 100 .
