Description

Technical Field

[0001] This invention relates to a rapid erection protective device for the conversion of hazardous materials storage tanks between peacetime and wartime use, belonging to the field of engineering safety protection. Background Technology

[0002] As large-capacity storage devices (such as oil, chemical raw material, and liquefied natural gas storage tanks), storage tanks are highly susceptible to explosion due to the dense oil and gas clouds within their confined space after being attacked by weapons. The explosion blast could trigger a chain reaction of explosions and other catastrophic accidents, seriously threatening the safety of surrounding facilities. Researching peacetime-wartime conversion protection devices for storage tanks can ensure normal operation of petrochemical bases during peacetime and allow for rapid deployment in wartime to reduce damage from attacks on storage tanks, which is of great significance for the safety protection of petrochemical enterprises.

[0003] Currently, the external protection of hazardous materials storage tanks mainly uses fixed reinforced concrete shelters or protective walls. These structures, built around the tank using cast-in-place or precast concrete walls, offer strong resistance to impacts, but are permanent facilities that occupy surrounding space for extended periods, severely impacting daily inspections, maintenance, and emergency repairs. Furthermore, their massive weight places high demands on the foundation's bearing capacity, making direct installation on existing tank sites difficult. More critically, these structures cannot be converted between peacetime and wartime use—they cannot be quickly dismantled to free up working space during peacetime, nor can they be rapidly reinforced or repaired during wartime, resulting in extremely poor flexibility.

[0004] On the other hand, existing mobile protective facilities are mostly temporary enclosures, such as steel plates, sandbags, or gravel bags piled around the storage tank to form a protective layer. Although such facilities can be removed during peacetime, their structural strength is insufficient and they are difficult to effectively resist the penetration of explosive shock waves and high-speed fragments. In addition, the temporary piles lack reliable connections with the outer wall of the storage tank and the foundation, making them prone to overall overturning or displacement when subjected to an explosive impact, resulting in poor protective reliability. Summary of the Invention

[0005] The present invention provides a rapid erection protective device for the peacetime-wartime conversion of hazardous materials storage tanks in order to solve the problems existing in the prior art.

[0006] The technical solutions adopted in this invention are as follows:

[0007] A rapid-deployment protective device for the peacetime-wartime conversion of a hazardous materials storage tank, the protective device adopting a modular assembly structure and being detachably installed on the outside of the hazardous materials storage tank, comprising:

[0008] Pre-embedded foundations: Several pre-embedded foundations are buried underground in a regular shape at intervals;

[0009] The protective frame includes columns, crossbars and outward suspension rods. The column bases are fixed to the pre-embedded foundations. Several crossbars are fixed between adjacent main columns and combined with the columns to form a main frame body with several grid holes. Several outward suspension rods are fixed at the top of the main frame body, and all outward suspension rods extend outward away from the center of the main frame body.

[0010] Composite protective plate, one composite protective plate is fixed in each grid hole of the protective frame;

[0011] Protective netting is installed on the outside and top of the protective frame.

[0012] Furthermore, the embedded foundation is provided with connecting bolts for connecting and fixing with the column, and a protective cover plate is provided at each embedded location of the embedded foundation, which is installed in a detachable manner to seal the embedded foundation.

[0013] Furthermore, the column is composed of several square steel pipes joined vertically together using flanges.

[0014] Furthermore, the outer wall of the main column is fixed with multiple stepped surfaces at intervals along the height direction. At both ends of the crossbar, there are slots that are adapted to the stepped surfaces. After the slots are inserted into the stepped surfaces, pins are inserted into the stepped surfaces to fix the main column and the crossbar.

[0015] Furthermore, the device also includes a support rod, a support platform is provided on the outer wall of the storage tank, a slot is provided at one end of the support rod, and a rib adapted to the slot is provided on the support platform; the other end of the support rod is fixed to the column by a pin.

[0016] Furthermore, the bottom end of the extended suspension rod is provided with a rectangular block with an opening slot. The opening slot of the rectangular block is engaged with the crossbar at the top of the protective frame, and a wing screw is inserted through the opening slot of the rectangular block.

[0017] Furthermore, the protective frame is provided with several mounting blocks, and the two ends of the mounting blocks are provided with rectangular grooves. One side of the rectangular groove is engaged with the crossbar and a wing screw is inserted through the rectangular groove on the side to fix the mounting block and the crossbar. The upper and lower ends of the composite protective plate are engaged in the rectangular grooves of the corresponding side mounting blocks.

[0018] Furthermore, the composite protective plate includes a galvanized steel plate and a concrete plate, with the concrete plate placed between the two galvanized steel plates, wherein a polyurea explosion-proof coating layer is sprayed on the outer surface of the outer galvanized steel plate.

[0019] Furthermore, the protective netting includes an inner net, an outer net, a first top net, and a second top net. The inner net covers the protective frame, the outer net is formed into a cylindrical shape and placed outside the inner net, and a pre-filling cavity is formed between the outer net and the inner net. The first top net is placed above the top of the storage tank, and the edge of the first top net extends above the pre-filling cavity. The outer edge of the second top net is fixed to the top of the outer net and the extended suspension rod.

[0020] Furthermore, both the intranet and the extranet have two doors that can be opened.

[0021] The present invention has the following beneficial effects:

[0022] (1) By setting up a pre-filled cavity between the inner and outer nets, there is no filling material in the cavity under normal circumstances. The self-weight of the protective net is only the weight of the wire mesh. The overall structure is much lighter than the fixed concrete protective structure, which greatly reduces the long-term static load requirements of the pre-embedded foundation. The existing storage tank site can be modified without the need for foundation reinforcement. In wartime, sandbags, soil bags and other buffer materials can be quickly filled into the cavity to form a gradient composite protective layer in a short time. At the same time, it solves the core problems of fixed protection being unable to be converted between peacetime and wartime and the insufficient strength of temporary stacked protection.

[0023] (2) The protective device adopts a fully modular assembly structure. The columns are spliced ​​by flanges, the crossbars are inserted into the step surface by pins, and the extended suspension rods are snapped by rectangular blocks and fixed with wing screws. All components are detachable mechanical connections, eliminating the need for on-site welding operations. Only simple tools are needed to achieve quick assembly and disassembly, significantly shortening the wartime erection and peacetime-wartime conversion cycle.

[0024] (3) By extending outwards and fixing the double-layer split top net through the outward extension suspension rod, a fully enclosed top cover is formed on the basis of facade protection, which can effectively intercept and deflect munitions, suicide drones and explosive fragments dropped by low-altitude drones; the composite protective plate and the double-layer protective net form a gradient protection structure, which greatly improves the overall resistance of the device to explosive shock waves and high-speed fragment penetration.

[0025] (4) The pre-embedded foundation is sealed with a protective cover plate during peacetime to prevent corrosion caused by long-term exposure of the pre-embedded connecting bolts and the entry of debris into the pre-embedded hole, ensuring that it can be quickly activated in wartime, and the connection strength and reliability meet the wartime protection requirements.

[0026] (5) An openable door is provided on the outer network, which facilitates personnel to enter the pre-filled cavity to carry out filling operations or to inspect and maintain the outer wall of the storage tank; at the same time, the support rod is inserted and matched with the support platform of the outer wall of the storage tank, which enhances the stability of the frame.

[0038] The invention will now be further described with reference to the accompanying drawings.

[0039] like Figure 1 As shown, this invention discloses a rapid deployment protective device for the peacetime-wartime conversion of a hazardous materials storage tank. The device is arranged around the hazardous materials storage tank 100, employing a modular assembly structure and being detachably installed on the outside of the tank. The entire device can be deployed with low interference in peacetime and rapidly assembled into a full protective structure in wartime, achieving rapid peacetime-wartime conversion.

[0040] like Figure 2 As shown, several pre-embedded foundations 210 are buried underground in a circular array along the circumference of the storage tank 100. Each pre-embedded foundation 210 has a pre-embedded connecting bolt 220 embedded inside, with the top of the pre-embedded connecting bolt 220 facing the ground.

[0041] like Figure 3As shown, each pre-embedded foundation 210 has a removable protective cover plate 230 installed at the top opening. After the protective cover plate 230 is closed, its top surface is flush with the ground, completely sealing the opening of the pre-embedded foundation 210, preventing the pre-embedded connecting bolts 220 from being exposed and corroding for a long time, and preventing debris from entering the pre-embedded hole. Under normal conditions, the closed pre-embedded foundation 210 does not affect the normal passage of personnel and vehicles in the site or the daily operation and maintenance of the storage tank.

[0042] When initiating protective erection in a wartime state, first remove the protective cover plate 230 from the top of the embedded foundation 210, exposing the embedded connecting bolts 220 inside. Then, align and lock the column base of the column 310 with the embedded connecting bolts 220, completing the rigid connection between the column 310 and the embedded foundation 210, providing a stable vertical load-bearing foundation for the entire protective structure. The column 310 is composed of several square steel pipes coaxially spliced ​​vertically through flanges 330. The number of square steel pipes spliced ​​can be adjusted according to the actual height of the storage tank 100 to adapt to the protection height requirements of different specifications of storage tanks.

[0043] like Figure 4 As shown, the outer wall of the column 310 is fixed with multiple stepped surfaces 341 at intervals along the height direction. The ends of the crossbar 320 are provided with slots that match the stepped surfaces 341. During assembly, the slots at both ends of the crossbar 320 are inserted into the stepped surfaces 341 of two adjacent columns 310, and then the pins 342 are inserted into the pre-drilled holes in the stepped surfaces 341, thus completing the locking and fixing of the column 310 and the crossbar 320. After multiple crossbars 320 and multiple columns 310 are sequentially spliced ​​and combined, a protective frame body with several grid holes is formed. The entire frame body surrounds the outside of the storage tank 100, forming the core load-bearing frame of the protective structure.

[0044] like Figure 5 As shown, a support rod 350 is provided between the protective frame and the storage tank 100. The support rod 350 is horizontally supported between the column 310 and the outer wall of the storage tank 100, providing multi-point lateral support for the entire protective frame, enhancing the impact resistance and stability of the structure, and preventing the frame from overturning or shifting laterally when subjected to an explosion impact.

[0045] Combination Figure 6 A support platform 110 is welded to the outer wall of the storage tank 100. The support platform 110 is arranged at intervals with the column 310 along the circumference of the storage tank 100. An outwardly extending reinforcing bar is fixed on the support platform 110. The end of the support rod 350 facing the storage tank 100 has a slot that matches the reinforcing bar. The other end of the support rod 350 is fixed to the column 310 by a pin. During assembly, the slot of the support rod 350 is aligned and inserted into the reinforcing bar of the support platform 110, and the installation of the support rod can be completed quickly without on-site welding. The assembly and disassembly are convenient and efficient.

[0046] like Figure 7 As shown, the crossbar 320 of the protective frame is equipped with several mounting blocks 410. Both ends of the mounting block 410 are provided with rectangular slots. One side of the rectangular slot is engaged with the outside of the crossbar 320. The wing screw 420 is inserted into the reserved hole of the rectangular slot on this side and locked, so as to firmly fix the mounting block 410 to the crossbar 320.

[0047] The upper and lower ends of the composite protective plate are respectively engaged in the rectangular grooves on the other side of the two corresponding mounting blocks 410, thereby realizing the rapid assembly of a single composite protective plate with the crossbar 320.

[0048] The composite protective plate comprises a galvanized steel plate 431 and a concrete plate 432. The concrete plate 432 is sandwiched between two layers of galvanized steel plates 431, forming a three-layer sandwich composite structure. The outer surface of the outer galvanized steel plate 431 is coated with a polyurea explosion-proof coating layer, which can dissipate the energy of the blast shock wave and high-speed fragments layer by layer, significantly improving the structure's impact resistance and penetration resistance. During assembly, the galvanized steel plate 431 and the concrete plate 432 are stacked and then fixed together with bolts. Each grid hole of the protective frame corresponds to a composite protective plate, and multiple composite protective plates are continuously arranged along the circumference and vertical of the protective frame, forming a complete vertical impact-resistant protective layer surrounding the storage tank 100, which can effectively resist the impact damage of the blast shock wave and high-speed fragments on the tank body. Figure 9 .

[0049] like Figure 8 As shown, the extended suspension rods 360 are used to fix the top protective structure. They are fixed to the top of the protective frame body, and all extended suspension rods 360 extend outwards away from the center of the frame body. The inner connecting end of the extended suspension rod 360 is fixed with a rectangular block 361 with an open slot. During assembly, the open slot of the rectangular block 361 is snapped onto the crossbar 320 at the top of the protective frame, and then the wing bolt is inserted into the reserved through hole of the open slot of the rectangular block 361 and locked. This completes the quick fixing of the extended suspension rod 360 to the protective frame. The whole process does not require on-site welding, which is suitable for the use of rapid deployment in combat.

[0050] like Figure 10 As shown, after the full mesh layout of the composite protective plate is completed, the inner mesh 511 is wrapped and fixed to the outside of the protective frame. The edge of the inner mesh 511 is fixed to the uprights 310 and crossbars 320 of the protective frame, forming an inner protective mesh structure that is tightly attached to the protective frame, providing a basic constraint structure for the subsequent composite protective layer.

[0051] like Figure 11As shown, an outer net 512 is provided outside the inner net 511. The outer net 512 forms a cylindrical structure surrounding the outer side of the inner net 511, creating a closed pre-filled cavity between the outer net 512 and the inner net 511. The outer net 512 is provided with at least two openable doors to facilitate personnel entering the pre-filled cavity for filling operations. The inner net is also provided with openable doors, which can be opened during normal times to complete routine inspections and maintenance of the tank's outer wall.

[0052] A first top net is provided above the top of the storage tank 100. The first top net is laid flat and its outer edge extends to the area above the pre-filled cavity between the inner net 511 and the outer net 512. The outer edge of the second top net is fixedly connected to the top of the outer net 512 and the outer end of the extended suspension rod 360 to form the outer enclosure structure of the top.

[0053] Under normal conditions, the pre-filled cavity is empty, with only the inner mesh 511 and outer mesh 512 wire mesh structure remaining. Its weight is extremely low, and it will not generate additional long-term static load on the pre-embedded foundation 210. At the same time, the transparent cavity structure will not obstruct the inspection line of the storage tank, nor will it affect the normal heat dissipation of the tank.

[0054] In a state of emergency, sandbags, soil bags, or water-absorbing expansion bags can be quickly stacked into the pre-filled cavity through the outer mesh 512 door to fill the entire cavity, transforming the double-layer wire mesh structure into a composite protective structure with a wire mesh-constrained filling layer. Simultaneously, as the height of the filling material in the pre-filled cavity increases, the first top mesh is lifted by the filling material and rests on its surface. At this point, more cushioning material can be stacked above the first top mesh, forming a top filling protective layer above the top of the storage tank 100. A second top mesh covers and constrains the outside of this top filling layer, preventing the explosive shockwave from blowing away or overturning the filling material. Ultimately, a gradient protection system covering the entire facade and top is formed, simultaneously resisting multiple threats from explosive shockwaves, high-speed fragments, and low-altitude drone attacks.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
