Description

Technical Field

[0001] This invention relates to the field of antistatic flooring technology, specifically an anti-cracking device based on a large-area antistatic surface of metal aggregate in an industrial plant. Background Art

[0002] Industrial plants refer to various buildings directly used for production or supporting production. They include main workshops, auxiliary rooms, and ancillary facilities. All factory buildings in industrial, transportation, commercial, construction, research, and educational institutions should be included. In addition to production workshops, industrial plants also include their ancillary buildings.

[0003] Industrial plants can be classified into single-story and multi-story industrial buildings according to their architectural structure. Multi-story industrial buildings are mostly found in light industry, electronics, instrumentation, communications, and pharmaceutical industries. Production plants in industries such as machining, metallurgy, and textiles are generally single-story industrial buildings, and depending on production needs, they are more often multi-span single-story industrial plants, that is, multi-span plants arranged side by side in parallel, with each span being the same or different as needed.

[0004] For industrial production facilities, the impact of static electricity is often immeasurable, especially for electronics factories. If static electricity cannot be effectively controlled, a large number of defective products are likely to occur during the production process. As the number of defective products increases and they appear in various locations within the production facility, significant losses can easily occur.

[0005] As a primary measure for industrial anti-static measures, ground anti-static flooring typically employs three methods: conductive flooring, anti-static base coatings, and conductive mats. For conductive flooring, in areas with high loads, anti-static terrazzo and NFJ metal aggregate anti-static flooring are commonly used. Comparing anti-static terrazzo and NFJ metal aggregate anti-static flooring, NFJ metal aggregate anti-static flooring uses rare earth iron alloy, which, due to its rust-free properties, maintains its anti-static performance. Furthermore, because it uses metallic aggregate, its high strength allows it to withstand very high loads, with a maximum unit load reaching 120 tons per square meter. Additionally, the construction of NFJ metal aggregate flooring is much simpler than that of anti-static terrazzo, and it does not require a static grounding network.

[0006] When existing metal aggregate flooring is used extensively in industrial plants, due to the large area of ​​the plant, it is easily affected by factors such as the characteristics of the flooring material, temperature stress, uneven load, and base deformation over time, resulting in localized cracking of the floor. As waste, dust, water, and other substances generated in the production area enter the cracked areas, it can easily affect the anti-static performance and service life of the flooring. Summary of the Invention

[0007] To overcome the shortcomings of existing metal aggregate flooring systems in large-scale industrial plant applications, which are susceptible to cracking due to factors such as material properties, temperature stress, uneven load, and base layer deformation, thus affecting the antistatic performance and service life of the flooring, this application provides a crack prevention device based on a large-area metal aggregate antistatic surface in industrial plants. This device involves installing a monitoring component between the antistatic surface layer and the intermediate buffer layer, using distributed optical fiber strips on the monitoring component to monitor the stress state of the antistatic surface layer. A reinforced base layer is formed by pouring concrete around a flexible conductive mesh, connecting multiple connectors... Multiple second conductive strips are embedded inside the reinforcing base layer through the second slot carrying multiple first conductive strips and the first slot carrying multiple first conductive strips. The top surface of the connector is flush with the top surface of the reinforcing base layer, allowing the entire flexible conductive mesh to be integrated into the interior of the reinforcing base layer as its skeleton structure. While ensuring structural strength, it also has conductivity and a certain degree of ductility. This is beneficial for improving the recovery ability of the antistatic floor after deformation under load, in conjunction with the antistatic surface layer, intermediate buffer layer and reinforcing base layer. It also minimizes the possibility of cracks caused by local pressure on the antistatic floor and allows for monitoring of the stress on the antistatic floor during use, facilitating timely repair and replacement.

[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0009] A crack prevention device based on a large area of ​​antistatic metal aggregate surface in an industrial plant includes a flexible conductive mesh, a monitoring component, and an antistatic ground, with the monitoring component located at the bottom of the flexible conductive mesh.

[0010] The anti-static floor adopts a layered design to support the laying of flexible conductive mesh and monitoring components;

[0011] The antistatic floor includes an antistatic surface layer, an intermediate buffer layer at the bottom of the antistatic surface layer, and a reinforcing base layer at the bottom of the intermediate buffer layer.

[0012] The flexible conductive mesh includes multiple first conductive strips and multiple second conductive strips. The multiple first conductive strips and multiple second conductive strips are all arranged at equal intervals and are respectively arranged in two different planes, one above the other. The multiple first conductive strips are all perpendicular to the multiple second conductive strips.

[0013] The monitoring component includes a distributed optical fiber strip, one end of which is equipped with a laser and the other end of which is equipped with a detector. The distributed optical fiber strip is arranged in a serpentine shape between the anti-static surface layer and the intermediate buffer layer.

[0014] The flexible conductive mesh provides structural support for the entire antistatic floor within the reinforced base layer, while the monitoring component monitors stress distribution and microcrack signals at the bottom of the antistatic surface layer.

[0015] In one possible implementation, a connecting seat is provided at the intersection of the plurality of second conductive strips and the plurality of first conductive strips. The top of the connecting seat is provided with a first slot and a second slot. The depth of the second slot is greater than the depth of the first slot. The second conductive strip overlaps the bottom inner wall of the second slot, and the first conductive strip overlaps the bottom inner wall of the first slot.

[0016] In one possible implementation, the connector is integrally machined from two symmetrical frustums and a central cylinder. The bottom of the connector is fixed to the ground, and the exterior of the flexible conductive mesh is reinforced with concrete to form a base layer, so that the top surface of the connector is flush with the top surface of the base layer.

[0017] In one possible implementation, the plurality of first conductive strips and the plurality of second conductive strips are all made of copper-nickel alloy and are in the shape of a cylindrical tube.

[0018] In one possible implementation, multiple antistatic flooring units are distributed in a square pattern on the ground, with an adaptive expansion and contraction structure between adjacent antistatic flooring units. The four adaptive expansion and contraction structures between four adjacent antistatic flooring units arranged in a square pattern are combined to form a cross.

[0019] In one possible implementation, the adaptive telescopic structure includes a support base with a filler strip on the top. The support base is composed of a semi-cylindrical rib at the top and a rectangular rib at the bottom. Additional support strips are provided between the long sides of the filler strip and the rectangular ribs. The distance between the top surface of the filler strip and the bottom surface of the support base is the same as the thickness of the anti-static floor.

[0020] In one possible implementation, the intermediate buffer layer is made of a conductive gel layer of silicone-based conductive adhesive, and the side surface of the filler strip near the antistatic floor is provided with a plate extending into the interior of the intermediate buffer layer, connecting the additional support strip and the intermediate buffer layer together.

[0021] In one possible implementation, corner blocks are integrally formed at both ends of the support base. A second Y-shaped wire-passing groove is formed inside both ends of the support base. A first wire-passing groove is formed inside both ends of the additional support strip. A storage slot is formed at the top of one end of each corner block. Two branches of the second wire-passing groove are connected to the outer sides of one end of the support base, and the main branch of the second wire-passing groove is connected to the storage slot on the corner block. The distributed optical fiber strip located between the antistatic surface layer and the intermediate buffer layer converges at one corner of the antistatic ground and passes through the first wire-passing grooves on two mutually perpendicular additional support strips. After passing through the second wire-passing groove, it converges inside the storage slots on two adjacent corner blocks.

[0022] In one possible implementation, the corner block has an isosceles right triangle cross section, and the four support bases in a cross shape snap the four corner blocks together to form a regular quadrilateral, so that the storage slots on the four corner blocks form a cylindrical groove. The detector and laser are assembled into the interior of the cylindrical groove. The top of the cylindrical groove is sealed between the four corner blocks by a snap-on cover, and the top surface of the snap-on cover, the top surface of the filling strip, and the top surface of the anti-static floor are kept in the same horizontal plane.

[0023] In one possible implementation, the antistatic surface layer is made of metal aggregate incorporating micron-sized shape memory alloy particles, and simultaneously embeds microcapsules containing conductive repair agents therein.

[0024] The beneficial effects of this application are as follows:

[0025] Firstly, in this solution, a monitoring component is installed between the antistatic surface layer and the intermediate buffer layer on the antistatic floor. Distributed optical fiber strips on the monitoring component monitor the stress state of the antistatic surface layer. Concrete is poured outside the flexible conductive mesh to form a reinforced base layer. Multiple connectors are embedded inside the reinforced base layer, with multiple second conductive strips supported by the second slot and multiple first conductive strips supported by the first slot. The top surface of the connectors is flush with the top surface of the reinforced base layer, allowing the entire flexible conductive mesh to be integrated into the interior of the reinforced base layer as its skeleton structure. This ensures structural strength while also providing conductivity and a certain degree of ductility. This is beneficial for improving the recovery ability of the antistatic floor after deformation under load, in conjunction with the antistatic surface layer, intermediate buffer layer, and reinforced base layer. It also minimizes the possibility of cracks caused by localized pressure on the antistatic floor. Furthermore, monitoring the stress state of the antistatic floor during use facilitates timely repair and replacement.

[0026] Secondly, in this solution, an intermediate buffer layer made of silicon-based conductive adhesive is used to form a support at the bottom of the antistatic surface layer. With the help of the antistatic surface layer made of metal aggregate mixed with micron-sized shape memory alloy particles, and microcapsules containing conductive repair agents embedded in the antistatic surface layer, the antistatic surface layer and the intermediate buffer layer can work together to improve the recovery ability of the antistatic floor when it is subjected to stress deformation. When cracks appear inside the antistatic surface layer, the microcapsules containing conductive repair agents rupture and squeeze out the conductive repair agents to repair the cracks, ensuring the conductivity of the antistatic surface layer.

[0027] Thirdly, in this solution, by setting an adaptive expansion structure between two adjacent antistatic floors, the two adjacent antistatic floors are separated and placed in an independent state. This makes it easier to replace and repair a single antistatic floor when it suffers significant damage, without causing large-area damage to the floor. At the same time, with the help of the filling strips and intermediate buffer layer on the adaptive expansion structure, the vibration of the antistatic floor can be absorbed and the thermal expansion and contraction deformation of the antistatic floor can be adapted.

[0028] Fourth, in this solution, by concentrating the two ends of the distributed optical fiber strip between the antistatic surface layer and the intermediate buffer layer at one corner of the antistatic ground, and passing through the inside of the second cable tray, and concentrating them inside the receiving slots on two adjacent corner blocks, the detector and laser can be assembled into the inside of the cylindrical slot, completing the overall installation of the monitoring component, and providing convenience for the maintenance and troubleshooting of the monitoring component.

[0044] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0045] Example 1:

[0046] This embodiment describes the specific structure of an anti-cracking device based on the antistatic surface of a large area of ​​metal aggregate in an industrial plant. See details below. Figures 1-5 and Figure 9 As shown, it includes a flexible conductive mesh 3, a monitoring component 4 disposed at the bottom of the flexible conductive mesh 3, and an anti-static ground 1 with a layered design. The anti-static ground 1 includes an anti-static surface layer 101, an intermediate buffer layer 102 disposed at the bottom of the anti-static surface layer 101, and a reinforcing base layer 103 disposed at the bottom of the intermediate buffer layer 102.

[0047] like Figure 2and Figure 3 As shown, the flexible conductive mesh 3 includes multiple first conductive strips 302 and multiple second conductive strips 303. The multiple first conductive strips 302 and multiple second conductive strips 303 are all arranged at equal intervals and are respectively arranged in two different planes, one above the other. The multiple first conductive strips 302 are all perpendicular to the multiple second conductive strips 303.

[0048] When multiple first conductive strips 302 and multiple second conductive strips 303, which are equally spaced and located on the same plane, act on two different planes, the multiple first conductive strips 302 and multiple second conductive strips 303 can be kept in a vertical state to form a mesh structure, which can improve the pressure-bearing capacity of the reinforced base layer 103 itself.

[0049] Meanwhile, multiple first conductive strips 302 and multiple second conductive strips 303 are made using copper-nickel alloy. The high strength, high corrosion resistance, high hardness, high resistance and high thermoelectric properties of copper-nickel alloy can reduce the temperature coefficient of resistivity and ensure mechanical and physical properties. At the same time, its excellent ductility can be used to ensure that the reinforcing base layer 103 has good conductivity and ductility. This can help to disperse stress when the reinforcing base layer 103 bears the load and prevent the bottom layer from cracking.

[0050] In addition, by setting multiple first conductive strips 302 and multiple second conductive strips 303 into a cylindrical shape, it is beneficial to save materials and reduce the use of raw materials in copper-nickel alloy, thereby reducing costs. Moreover, since multiple first conductive strips 302 and multiple second conductive strips 303 are all cylindrical, their function of dispersing the internal stress of the reinforcing base layer 103 will not be affected. Ultimately, the flexible conductive mesh 3 provides structural support for the entire antistatic ground 1 inside the reinforcing base layer 103.

[0051] Secondly, to facilitate fixing multiple first conductive strips 302 and multiple second conductive strips 303 together, and to ensure that the multiple first conductive strips 302 and multiple second conductive strips 303 are respectively located in a fixed plane, such as... Figures 2 to 4 As shown, a connecting seat 301 is provided at the intersection of multiple second conductive strips 303 and multiple first conductive strips 302. The top of the connecting seat 301 is provided with a first slot 5 and a second slot 6. By making the depth of the second slot 6 greater than the depth of the first slot 5, when a second conductive strip 303 passes through the inside of the second slot 6 on multiple connecting seats 301, the second conductive strip 303 overlaps the bottom inner wall of the second slot 6, which can realize the positioning of the second conductive strip 303.

[0052] Meanwhile, by passing a first conductive bar 302 through the second slots 6 in multiple connection seats 301, the first conductive bar 302 can be lapped at the bottom inner wall of the first slot 5, realizing the positioning of the first conductive bar 302. Finally, multiple second conductive bars 303 and multiple first conductive bars 302 are assembled into a mesh;

[0053] Furthermore, to ensure the structural strength and support effect of the connection seat 301 itself, as Figure 4 shown, the connection seat 301 is integrally processed from two symmetric frustums and a central cylinder. By fixing the bottom of the connection seat 301 to the ground, when concrete is poured outside the flexible conductive network 3 to form a reinforced base layer 103 and the top surface of the connection seat 301 is flush with the top surface of the reinforced base layer 103, the entire flexible conductive network 3 can be combined inside the reinforced base layer 103 as its skeleton structure, having both conductivity and certain ductility while ensuring the structural strength;

[0054] As Figure 3 and Figure 5 shown, the monitoring component 4 includes a distributed optical fiber strip 401. One end of the distributed optical fiber strip 401 is provided with a laser 403, and the other end of the distributed optical fiber strip 401 is provided with a detector 402. The distributed optical fiber strip 401 is arranged in a serpentine shape between the anti-static surface layer 101 and the intermediate buffer layer 102;

[0055] Among them, by arranging the distributed optical fiber strip 401 in a serpentine shape between the anti-static surface layer 101 and the intermediate buffer layer 102 to reach a distributed state, when the top of the anti-static surface layer 101 bears a load and deforms, a certain bending state will occur in a part of the distributed optical fiber strip 401. At this time, by virtue of the unique positions of the points at different lengths of the distributed optical fiber strip 401, the position where the anti-static surface layer 101 deforms or even cracks can be determined by monitoring the multi-point deformation;

[0056] Secondly, for the situation where the distributed optical fiber strip 401, the detector 402 and the laser 403 monitor the deformation or even cracking inside the anti-static surface layer 101, based on the Brillouin scattering theory, since the scattering process in the optical fiber mainly includes Brillouin scattering, Raman scattering and Rayleigh scattering. And Brillouin scattering is one of them. During the process of local compression and deformation of the distributed optical fiber strip 401, the deformation frequency and deformation degree can be obtained in the system supporting the monitoring component 4 (as Figure 9 shown, the system supporting the monitoring component 4 can be directly purchased with supporting equipment and supporting programs);

[0057] The deformation frequency can be viewed from the frequency of the ground being subjected to a monitorable load, while the degree of deformation is based on the degree of deformation of the antistatic surface layer 101 under load, including elastic deformation that can be automatically repaired and permanent deformation that cannot be repaired, i.e., cracking of the surface of the antistatic surface layer 101, so that the monitoring component 4 can monitor the stress distribution and microcrack signals at the bottom of the antistatic surface layer 101.

[0058] Furthermore, in order to improve the ability of the antistatic surface layer 101 to automatically recover after deformation, the antistatic surface layer 101 is made by incorporating micron-sized shape memory alloy particles into metal aggregate. When the antistatic surface layer 101 is subjected to stress deformation under load, the antistatic surface layer 101 can be partially restored to its state before deformation.

[0059] Meanwhile, by pre-embedding microcapsules containing conductive repair agents in the metal aggregates and micron-sized shape memory alloy particles used to make the antistatic surface layer 101, when the antistatic surface layer 101 is subjected to a large load and cracks appear, the repair agent can be released during the crack propagation process to fill the gaps, so as to avoid the problem of local short circuits caused by cracks in the antistatic surface layer 101 and ensure the conductivity of the antistatic surface layer 101.

[0060] In some examples, multiple antistatic flooring units 1 are distributed in a square pattern on the ground. An adaptive expansion structure 2 is set between two adjacent antistatic flooring units 1. By combining the four adaptive expansion structures 2 between four adjacent antistatic flooring units 1 arranged in a square pattern to form a cross, the multiple antistatic flooring units 1 laid in sections can be connected into one unit, eliminating the gaps between two adjacent antistatic flooring units 1. When a local antistatic flooring unit 1 is severely damaged and cannot automatically adjust to meet the antistatic effect, the replacement work can be completed by removing and repairing the antistatic flooring unit 1, without the need for large-scale ground repairs, which helps to save costs.

[0061] The above design forms a reinforced base layer 103 by pouring concrete on the outside of the flexible conductive mesh 3. Multiple connectors 301 are embedded in the interior of the reinforced base layer 103, carrying multiple second conductive strips 303 through the second slot 6 and multiple first conductive strips 302 through the first slot 5. The top surface of the connectors 301 is flush with the top surface of the reinforced base layer 103, so that the entire flexible conductive mesh 3 can be integrated into the interior of the reinforced base layer 103 as its skeleton structure. While ensuring structural strength, it also has conductivity and a certain degree of ductility.

[0062] Meanwhile, by using an intermediate buffer layer 102 made of silicon-based conductive adhesive to form a support at the bottom of the antistatic surface layer 101, and by using the antistatic surface layer 101 made of metal aggregate mixed with micron-sized shape memory alloy particles, and the microcapsules containing conductive repair agent pre-embedded inside the antistatic surface layer 101, when the top surface of the antistatic floor 1 is under pressure, the antistatic surface layer 101 and the intermediate buffer layer 102 can work together to improve the recovery ability of the antistatic floor 1 when it is deformed by stress. Moreover, when cracks appear inside the antistatic surface layer 101, the microcapsules containing conductive repair agent rupture and squeeze out the conductive repair agent to repair the cracks, thus ensuring the conductivity of the antistatic surface layer 101.

[0063] Furthermore, by laying monitoring components 4 on the antistatic surface layer 101 and the intermediate buffer layer 102, the distributed optical fiber strips 401 on the monitoring components 4 are arranged in a serpentine pattern. When the top of the antistatic surface layer 101 is subjected to load and deforms, the distributed optical fiber strips 401 will locally bend. Since the locations of the points of different lengths of the distributed optical fiber strips 401 are unique, the location of deformation or even cracking of the antistatic surface layer 101 can be determined by monitoring the deformation at multiple points, so as to achieve the effect of stress monitoring.

[0064] Example 2:

[0065] Based on Example 1, this example introduces the specific structure of the adaptive telescopic structure 2. The adaptive telescopic structure 2 includes a support base 202. A filling strip 201 is provided on the top of the support base 202. The support base 202 is composed of a semi-cylindrical rib at the top and a rectangular rib at the bottom. An additional support strip 205 is provided between the filling strip 201 and the two long sides of the rectangular rib.

[0066] By making the distance between the top surface of the filling strip 201 and the bottom surface of the support base 202 the same as the thickness of the antistatic floor 1, the adaptive telescopic structure 2 can fill the gap between two adjacent antistatic floors 1, separating the two adjacent antistatic floors 1 and making them independent of each other. This facilitates independent replacement and repair when a single antistatic floor 1 suffers significant damage, preventing large-area damage to the floor and ensuring that production cannot proceed normally.

[0067] Secondly, the intermediate buffer layer 102 is made of a conductive gel layer of silicone-based conductive adhesive, and the side surface of the filling strip 201 near the antistatic ground 1 is provided with a plate extending into the interior of the intermediate buffer layer 102, connecting the additional support strip 205 and the intermediate buffer layer 102 together. When the intermediate buffer layer 102 is performing buffering work, the filling strip 201 helps to absorb vibration and adapt to thermal expansion and contraction deformation.

[0068] The above design separates two adjacent antistatic floor surfaces 1 by setting an adaptive telescopic structure 2 between them, making them independent of each other. This facilitates independent replacement and repair when a single antistatic floor surface 1 suffers significant damage, without causing large-area damage to the floor.

[0069] Meanwhile, with the help of the filling strip 201 and the intermediate buffer layer 102 on the adaptive expansion and contraction structure 2, the vibration of the antistatic floor 1 can be absorbed and the thermal expansion and contraction deformation of the antistatic floor 1 can be adapted. The bottom of the filling strip 201 is supported by the support base 202 and two additional support strips 205, which can improve the ability to withstand stress deformation while ensuring the overall structural strength.

[0070] Example 3:

[0071] Based on embodiments 1 and 2, this embodiment introduces the specific structure of the adaptive telescopic structure 2. Both ends of the support base 202 are integrally formed with corner blocks 203. Both ends of the support base 202 are provided with Y-shaped second wire grooves 9. Both ends of the additional support strip 205 are provided with first wire grooves 8. The top of one end of the corner block 203 is provided with a storage slot 7.

[0072] Among them, by connecting the two branches of the second wire-threading groove 9 (based on the Y-shaped second wire-threading groove 9) to the outside of both sides of one end of the support base 202 respectively, the main body of the second wire-threading groove 9 (based on the Y-shaped second wire-threading groove 9) is connected to the storage slot 7 on the corner block 203.

[0073] Secondly, the corner block 203 has an isosceles right triangle cross section. The four support bases 202 in a cross shape snap the four corner blocks 203 into a regular quadrilateral, so that the storage slots 7 on the four corner blocks 203 form cylindrical slots. When the two ends of the distributed optical fiber strip 401 between the antistatic surface layer 101 and the intermediate buffer layer 102 are respectively concentrated at one corner of the antistatic ground 1 and pass through the first wire groove 8 on the two mutually perpendicular additional support strips 205, and after passing through the inside of the second wire groove 9, they are concentrated inside the storage slots 7 on the two adjacent corner blocks 203. The detector 402 and the laser 403 are assembled into the inside of the cylindrical slot, and the overall installation of the monitoring component 4 set between the antistatic surface layer 101 and the intermediate buffer layer 102 can be completed.

[0074] Meanwhile, the top of the cylindrical groove is sealed between the four corner blocks 203 by setting the buckle 204, and the top surface of the buckle 204, the top surface of the filling strip 201 and the top surface of the antistatic floor 1 are kept in the same horizontal plane, which is beneficial to fill the gap between the multiple antistatic floor 1s arranged in a matrix by using multiple adaptive telescopic structures 2.

[0075] The above design involves opening a second wire-passing groove 9 inside both ends of the support base 202 and a first wire-passing groove 8 inside both ends of the additional support strip 205. When the two ends of the distributed optical fiber strip 401 between the antistatic surface layer 101 and the intermediate buffer layer 102 are respectively concentrated at one corner of the antistatic ground 1 and pass through the first wire-passing groove 8 on the two mutually perpendicular additional support strips 205, and after passing through the inside of the second wire-passing groove 9, they are concentrated inside the receiving slot 7 on the two adjacent corner blocks 203. This allows the detector 402 and the laser 403 to be assembled into the inside of the cylindrical groove, completing the overall installation of the monitoring component 4. This provides convenience for the maintenance and troubleshooting of the monitoring component 4 (the detector 402 and the laser 403 are individually troubleshooted and tested, including but not limited to the connection point between the detector 402, the laser 403 and the distributed optical fiber strip 401. If no fault occurs at this point, but the monitoring component 4 cannot work, it can be inferred that the distributed optical fiber strip 401 has a local breakage, etc.).

[0076] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
