Description

Technical Field

[0001] This invention belongs to the field of fencing, and more specifically, relates to a closed device for anti-terrorism protection in water treatment plant areas. Background Technology

[0002] Anti-terrorism protective fencing is an important security facility in water treatment plant areas. Its core function is to achieve airtight protection of the plant area boundary, prevent illegal intrusion, spying, and entry of various foreign objects, and ensure the safety of water production and the security level of the plant area. It is mostly composed of multiple single-sided fence panels spliced ​​together to meet the special protection needs of water treatment plant areas.

[0003] Most existing airtight interlocking anti-terrorism protective fences rely solely on simple mechanical connectors for fixing between sections. In low-temperature environments, the joints of these fences are prone to freezing and blocking the auxiliary fixing channels. Furthermore, when the wind is strong, the sections are easily misaligned and sway, making it impossible to achieve timely auxiliary fixing and thus compromising the airtightness of the fence. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose and effectiveness of the anti-terrorism protection enclosure device for water treatment plant areas of this invention are achieved through the following specific technical means:

[0005] Its structure includes a protective base, a fixing head, a protective block, a reinforcing assembly, a sealed fence, a fixing plate, a slot, and an auxiliary slot. The protective base is fixed to the outer wall of the sealed fence. The fixing head and the sealed fence are an integrated structure. The protective block is fixed in the side slot of the sealed fence. The reinforcing assembly is securely installed in the side slot of the sealed fence through the protective block. The fixing plate is fixed by connecting two fixing heads. The sealed fence has a slot on the side away from the reinforcing assembly. The auxiliary slot and the sealed fence are an integrated structure.

[0006] The consolidation assembly includes a fixed rod, a spring, a push rod, an ice-breaking head, and a locking clamp. The push rod is sleeved on the outer surface of the fixed rod and is slidable. The spring is connected between the push rod and the fixed rod. The ice-breaking head is located on the outer surface of the push rod and is movable. The locking clamp is located between the two push rods. The fixed rod provides an axial installation and positioning base for the consolidation assembly.

[0007] As a further improvement of the present invention, the push rod includes a magnetic conductor, a retaining ring, a top, a limiting groove, a push spring, a movable groove, a rolling magnetic ball, and a main rod. The magnetic conductor is located at both ends of the movable groove. The retaining ring is fixed to the outer surface of the main rod. The top and the main rod are an integral structure. The push spring is installed in the limiting groove. The limiting groove and the top are an integral structure. The rolling magnetic ball is located in the movable groove and is movable. The limiting groove limits the compression and extension path of the push spring.

[0008] As a further improvement of the present invention, the ice-breaking head includes an ice-breaking body, a magnetic strip, and a limiting block. The magnetic strip and the ice-breaking body are an integrated structure. The limiting block is fixed to the surface of the ice-breaking body and is located in a limiting groove and connected to a pushing spring. The end of the ice-breaking body away from the magnetic strip is an inclined surface, which uses the extending force to break the thin ice at the joint gap.

[0009] As a further improvement of the present invention, the card holder includes a cross shaft, a cross clamp, a magnetic strip, a magnetic block, and a fixed base. The cross shaft is fixedly connected to the fixed base. The cross clamp performs cross synchronous movement through the cross shaft and assists in returning to its original position. The magnetic strip is fixed to the surface of the cross clamp. The magnetic block is connected to the cross clamp. The cross clamp achieves synchronous opening, closing, and resetting by relying on the cross shaft.

[0010] As a further improvement of the present invention, the slot includes a return spring, a top rod, a stabilizing groove, a force-bearing rod, and a movable channel. The return spring is installed between the top rod and the inner wall of the sealed enclosure groove. The top rod is connected to the force-bearing rod. The movable channel and the sealed enclosure are an integral structure. The stabilizing groove and the sealed enclosure are an integral structure. The top rod and the stabilizing groove are located at the same center. The movable channel limits the lateral movement trajectory of the top rod.

[0011] As a further improvement of the present invention, the two ends of the movable groove are inclined at a slight angle towards the middle to assist the magnetic rolling ball in resetting. When the magnetic rolling ball moves close to the magnetic conductor, it will transmit the magnetic force to the magnetic conductor. The retaining ring has a trumpet-shaped structure, and the inclined surface will not be blocked when passing the retaining clamp. After passing the inclined surface, it will stop at the straight end of the retaining ring for limiting. The inclined structure of the movable groove avoids the magnetic rolling ball from getting stuck.

[0012] As a further improvement of the present invention, the cross clamp is provided with two cross connections, which are synchronously expanded and retracted through the cross shaft. The magnetic strip and the magnetic block have magnetic force. The fixing seat assists in fixing the whole in the sealed enclosure groove. The magnetic strip corresponds to the magnetic conductor, and the magnetic block corresponds to the magnetic strip. After the magnetic conductor is magnetized, it generates a magnetic repulsion effect with the magnetic strip.

[0013] As a further improvement of the present invention, the outer opening of the stabilizing groove is a trumpet-shaped structure, which can finely adjust the movement of the auxiliary top head. The force rod can push the top rod to move along the movable channel. The return spring assists the top rod to return to its original position. The trumpet-shaped structure of the stabilizing groove can adapt to slight misalignment of the fence and realize guide insertion.

[0014] As a further improvement of the present invention, the protective base includes a rotating shaft, a protective layer, a control grid, an interceptor plate, and a scraper. The interceptor plate is controlled to be connected to the control grid via the rotating shaft. The protective layer and the control grid are an integrated structure. The scraper is connected to the bottom of the interceptor plate. The rotating shaft realizes the opening and closing rotation control of the interceptor plate.

[0015] As a further improvement of the present invention, the top of the control grid is an inclined surface to assist objects in sliding down. The scraper contacts the ground and scrapes away debris during operation. The inclined surface of the control grid can guide rainwater and fallen leaves to slide outwards, avoiding accumulation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Firstly, when an independent sealed fence and an adjacent sealed fence are subjected to different external forces, resulting in uneven shaking, this device can use the force of the shaking itself to trigger the reinforcement group to automatically extend into the slot for auxiliary fixation. This effectively limits the relative displacement of the two adjacent sealed fences, preventing the fixing plate from being bent or deformed due to inconsistent shaking amplitude and uneven force. This prevents gaps from forming between adjacent fences, ensuring that the sealed fence always maintains a good airtight state, guaranteeing the sealing and safety of the water treatment plant area's anti-terrorism protection, and avoiding the risk of intrusion due to gaps.

[0018] Secondly, adjacent airtight fences are fixed by connecting fixing heads with fixing plates, and the reinforcement group can be manually retracted and returned to its original position. When a piece of airtight fence malfunctions, is damaged and needs to be replaced, or needs to be disassembled for maintenance, it is not necessary to disassemble the entire fence system. Only the corresponding fixing plate needs to be removed and the reinforcement group needs to be reset, so that the piece of airtight fence can be disassembled and replaced separately. This greatly reduces the difficulty and cost of maintenance, reduces the impact on the normal operation of the entire anti-terrorism protection system, and improves maintenance efficiency.

[0019] Thirdly, for areas with large temperature differences, the joints between sealed fences are prone to forming thin ice due to water vapor condensation, which can block the extension channel of the reinforcement group and affect its auxiliary fixing action. This device, through the coordinated action of the ice-breaking head and push rod in the reinforcement group, can break the thin ice with the impact of the ice-breaking body when the reinforcement group is extended, ensuring that the reinforcement group can smoothly extend into the slot to complete the auxiliary fixing, avoiding the fence connection loosening and sealing failure due to icing, ensuring the stable operation of the device in low temperature environment, and adapting to the usage needs of water treatment plant areas under different climatic conditions.

[0020] Fourthly, the protective bottom, as the protective structure at the bottom of the enclosed fence, guides rainwater, fallen leaves, and other impurities outward through the inclined design of the control grid. It uses interception plates and scrapers to collect and clean the impurities. At the same time, the protective layer is tightly attached to the surface of the enclosed fence, which can effectively prevent water accumulation, decaying leaves and their corrosive substances from directly contacting the bottom of the enclosed fence. This prevents rust, corrosion, deformation and other damage to the bottom of the enclosed fence, extends the service life of the enclosed fence, and avoids gaps caused by bottom corrosion and damage, ensuring the overall airtight protection effect of the fence.

[0021] Fifth, the consolidation unit adopts a purely mechanical structure that combines magnetic triggering and spring drive. It does not rely on motors, sensors and other electronic control components, which not only reduces the manufacturing cost and failure probability of the device, but also enables automatic triggering by the force of the fence shaking in special circumstances such as sudden power outages and severe weather. This ensures the normal operation of auxiliary fixing, ice breaking and other functions, improves the reliability and anti-interference ability of the device, and meets the high reliability requirements of anti-terrorism protection in water treatment plant areas.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] Example 1:

[0039] As attached Figure 1 To be continued Figure 12 As shown:

[0040] This invention provides a sealing device for anti-terrorism protection in water treatment plant areas. Its structure includes a protective base 1, a fixing head 2, a protective block 3, a reinforcing group 4, a sealed fence 5, a fixing plate 6, a slot 7, and an auxiliary slot 8. The protective base 1 is fixed to the outer wall of the sealed fence 5. The fixing head 2 and the sealed fence 5 are an integrated structure. The protective block 3 is fixed in the side slot of the sealed fence 5. The reinforcing group 4 is securely installed in the side slot of the sealed fence 5 through the protective block 3. The fixing plate 6 connects two fixing heads 2 for fixation. The sealed fence 5 has a slot 7 on the side away from the reinforcing group 4. The auxiliary slot 8 and the sealed fence 5 are an integrated structure.

[0041] The consolidation assembly 4 includes a fixed rod 41, a spring 42, a push rod 43, an ice-breaking head 44, and a locking clamp 45. The push rod 43 is sleeved on the outer surface of the fixed rod 41 and is slidable. The spring 42 is connected between the push rod 43 and the fixed rod 41. The ice-breaking head 44 is located on the outer surface of the push rod 43 and is movable. The locking clamp 45 is located between the two push rods 43. The fixed rod 41 provides an axial installation and positioning base for the consolidation assembly 4, and the spring 42 provides axial extension and retraction elastic force for the push rod 43.

[0042] The push rod 43 includes a magnetic conductor 31, a retaining ring 32, a top 33, a limiting groove 34, a pushing spring 35, a movable groove 36, a rolling magnetic ball 37, and a main rod 38. The magnetic conductor 31 is located at both ends of the movable groove 36. The retaining ring 32 is fixed to the outer surface of the main rod 38. The top 33 and the main rod 38 are an integrated structure. The pushing spring 35 is installed in the limiting groove 34. The limiting groove 34 and the top 33 are an integrated structure. The rolling magnetic ball 37 is located in the movable groove 36 and is movable. The limiting groove 34 limits the compression and extension path of the pushing spring 35. The rolling magnetic ball 37 can move within the movable groove 36 as the sealed fence 5 sways.

[0043] The ice-breaking head 44 includes an ice-breaking body 61, a magnetic strip 62, and a limiting block 63. The magnetic strip 62 and the ice-breaking body 61 are an integrated structure. The limiting block 63 is fixed to the surface of the ice-breaking body 61 and is located in the limiting groove 34 and connected to the pushing spring 35. The end of the ice-breaking body 61 away from the magnetic strip 62 is an inclined surface, which uses the protruding impact to break the thin ice at the joint gap. The magnetic strip 62 is used to form a magnetic attraction with the magnetic block 54.

[0044] The positioning clamp 45 includes a cross shaft 51, a cross clamp 52, a magnetic strip 53, a magnetic block 54, and a fixing base 55. The cross shaft 51 is fixedly connected to the fixing base 55. The cross clamp 52 performs cross synchronous movement through the cross shaft 51 and assists in returning to its original position. The magnetic strip 53 is fixed to the surface of the cross clamp 52. The magnetic block 54 is connected to the cross clamp 52. The cross clamp 52 achieves synchronous opening, closing, and resetting by relying on the cross shaft 51. The fixing base 55 improves the overall installation stability of the positioning clamp 45.

[0045] The slot 7 includes a return spring 71, a push rod 72, a stabilizing groove 73, a force-bearing rod 74, and a movable channel 75. The return spring 71 is installed between the push rod 72 and the inner wall of the sealed enclosure 5. The push rod 72 is connected to the force-bearing rod 74. The movable channel 75 and the sealed enclosure 5 are an integral structure. The stabilizing groove 73 and the sealed enclosure 5 are an integral structure. The push rod 72 and the stabilizing groove 73 are located at the same center. The movable channel 75 limits the lateral movement trajectory of the push rod 72. The force-bearing rod 74 is used to receive external thrust and transmit it to the push rod 72.

[0046] The movable groove 36 is slightly inclined at both ends towards the middle to assist the magnetic rolling ball 37 in resetting. When the magnetic rolling ball 37 moves close to the magnetic conductor 31, it will transmit the magnetic force to the magnetic conductor 31. The retaining ring 32 has a trumpet-shaped structure. When the inclined surface passes the retaining clamp 45, it will not be blocked. After passing the inclined surface, it will stop at the straight end of the retaining ring 32 for limiting. The inclined structure of the movable groove 36 prevents the magnetic rolling ball 37 from getting stuck. The magnetic conductor 31 has two parts located on both sides of the magnetic rolling ball 37.

[0047] The cross clamp 52 has two cross connections, which are synchronously extended and retracted through the cross shaft 51. The magnetic strip 53 and the magnetic block 54 are magnetic. The fixing seat 55 assists in fixing the whole in the groove of the sealed fence 5. The magnetic strip 53 corresponds to the magnetic conductor 31, and the magnetic block 54 corresponds to the magnetic strip 62. After the magnetic conductor 31 is magnetized, it generates a magnetic repulsion with the magnetic strip 53. The magnetic block 54 and the magnetic strip 62 are separated and lose magnetic attraction. The limiting block 63 is pushed outward under the elastic force of the pushing spring 35. When there is no magnetic force pushing, the cross clamp 52 is in a normally closed locking state.

[0048] The outer opening of the stabilizing groove 73 is a funnel-shaped structure, which can finely adjust the movement of the auxiliary top head 33. The force rod 74 can push the top rod 72 to move along the movable channel 75. The return spring 71 assists the top rod 72 to return to its original position. The funnel-shaped structure of the stabilizing groove 73 can adapt to slight misalignment of the fence and realize guide insertion. The return spring 71 ensures that the top rod 72 is reset in the non-working state.

[0049] The specific usage and function of this embodiment are as follows:

[0050] In this invention, during assembly, the auxiliary groove 8 is connected to the corresponding fixed rod preset on the ground. The two adjacent sealed fences 5 are initially fixed by the fixed plate 6 connected to the fixed head 2. The fixed plate 6 can help the adjacent fences maintain alignment when the overall structure shakes slightly. When the external force is large and the sealed fence 5 is prone to misalignment and shaking, the rolling magnetic ball 37 moves within the movable groove 36 with the shaking. The rolling magnetic ball 37 approaches the magnetic conductor 31 on either side of the movable groove 36 and transmits the magnetic force to the magnetic conductor 31, causing the magnetic conductor 31 and the magnetic strip 53 to generate a magnetic repulsion force. Under the hinged cooperation of the cross shaft 51, the two cross clamps 52 unfold to both sides under the action of repulsion. The limiting resistance of the retaining ring 32 is released. The push rod 43 extends outward along the fixed rod 41 under the pushing force of the spring 42. At the same time, the cross clamps 52 open outward, causing the magnetic block 54 to release the magnetic attraction constraint on the magnetic strip 62. The limiting block 63 pushes the elastic force of the spring 35. The lower edge limiting groove 34 pushes outward, and the ice-breaking body 61 and the top head 33 break the thin ice formed at the joint of the sealed fence 5 under the action of the extension force, so that the push rod 43 can be smoothly inserted into the slot 7, and the stabilizing groove 73 calibrates and positions the top head 33, thereby realizing the stable connection between two adjacent sealed fences 5. When it is necessary to disassemble and replace a single sealed fence 5, the fixing plate 6 is first removed, and the force rod 74 is pushed along the moving track 75 by external force. The top rod 72 moves synchronously with the force rod 74 and pushes the push rod 43 inside the stabilizing groove 73 inward. The retaining ring 32 slides smoothly through the cross clamp 52 by its inclined surface and is locked and limited by the cross clamp 52 again. The magnetic block 54 attracts and resets the magnetic strip 62 through magnetic attraction, so that the consolidation group 4 is completely retracted into the protective block 3. At this time, the sealed fence 5 can be moved upward, so that the auxiliary groove 8 is removed from the corresponding fixing rod on the ground, and then the sealed fence 5 can be disassembled and assembled independently.

[0051] Example 2:

[0052] As attached Figure 13 To be continued Figure 14 As shown:

[0053] The protective base 1 includes a rotating shaft 11, a protective layer 12, a control grid 13, an interceptor plate 14, and a scraper 15. The interceptor plate 14 is controlled to be connected to the control grid 13 via the rotating shaft 11. The protective layer 12 and the control grid 13 are an integrated structure. The scraper 15 is connected to the bottom of the interceptor plate 14. The rotating shaft 11 realizes the opening and closing rotation control of the interceptor plate 14. The protective layer 12 is tightly attached to the sealed fence 5 to isolate corrosive media.

[0054] The top of the control grid 13 is an inclined surface to help objects slide down. The scraper 15 contacts the ground and scrapes away debris when in motion. The inclined surface of the control grid 13 can guide rainwater and fallen leaves to slide outward to avoid accumulation. The interception plate 14 works with the scraper 15 to collect debris in a concentrated manner.

[0055] The specific usage and function of this embodiment are as follows:

[0056] In this invention, when it rains, rainwater, along with fallen leaves and other impurities, flows down the outer wall of the sealed fence 5 to the control grid 13 on the protective base 1. Thanks to the preset tilt angle of the control grid 13, rainwater and fallen leaves and other impurities can be guided to the outside of the sealed fence 5, preventing impurities from accumulating in the gaps at the bottom of the fence. After the weather stabilizes and the rain recedes, fallen leaves and other impurities will remain and accumulate on the outside of the interception plate 14. At this time, the control grid 13 can be controlled by the back-end control system, which drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates, it drives the interception plate 14 to rotate synchronously. The scraper 15 connected to the bottom of the interception plate 14 moves along the ground, removing the fallen leaves accumulated at the bottom of the sealed fence 5. Impurities such as mud and sand are pushed outwards. The protective layer 12 and the control grid 13 are an integrated structure and are tightly attached to the outer wall of the sealed fence 5. This effectively isolates rainwater and impurities from direct contact with the surface of the sealed fence 5, preventing impurities from rotting and rainwater from causing rust, corrosion, and other damage to the sealed fence 5. After the interception plate 14 pushes all the accumulated impurities to one side and piles them up, the accumulated impurities can be cleaned up manually. This completely prevents fallen leaves, mud, sand, and other impurities from accumulating at the bottom of the sealed fence 5 for a long time, preventing them from clogging the auxiliary groove 8, eroding the protective bottom 1, or damaging the bottom airtightness of the sealed fence 5, thus ensuring the long-term stable operation of the entire anti-terrorism protective sealed device.
