[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Combine the following Figures 1 to 17 , describing an embodiment of the present invention.

[0046] The present invention provides a flexible blocking emergency protection structure suitable for protecting vertical energy storage tanks, such as vertical oil storage tanks, vertical energy storage tanks are referred to as energy storage tanks, such as Figures 1 to 3 and Figure 8 As shown, it comprises: a curtain-like main body 100, which comprises an inner core layer 1, an intermediate structure reinforcement layer 3 and a fire-resistant and flame-retardant layer 4 which are arranged in sequence from the inside to the outside; the intermediate structure reinforcement layer 3 is made of a material with sealing, impact resistance and high temperature resistance properties; the inner core layer 1 has two states of expansion and contraction; the intermediate structure reinforcement layer 3, the fire-resistant and flame-retardant layer 4 and the inner core layer 1 in the contracted state are all flexible and can be folded / stored. The top of the curtain-like body 100 is pre-installed on the top of the energy storage tank, and the curtain-like body 100 has a folded state and an unfolded state; the curtain-like body 100 in the folded state is placed on the top of the energy storage tank; the curtain-like body 100 in the unfolded state is laid on the side of the energy storage tank. It can be understood that under normal circumstances (not in use), the curtain-like body 100 is in a folded state and placed on the top of the energy storage tank. When there is a need for protection in some cases, the curtain-like body 100 is released manually or remotely, so that the bottom end of the curtain-like body 100 slides down under its own gravity and covers the side of the energy storage tank.

[0047] The flexible arresting emergency protection structure provided by the present invention has impact resistance, high temperature resistance and flame retardant properties. The present invention has multiple functions such as intercepting external impact fragments, resisting the impact of the energy storage tank's own explosion, and intercepting the splashing of high-temperature fragments generated by its own explosion. The flexible arresting emergency protection structure can be pre-equipped on the top of the energy storage tank. When it is needed, the flexible arresting emergency protection structure can be released to achieve the purpose of quickly equipping the energy storage tank with a protection structure, filling the gap in emergency protection of energy storage tanks and having good application prospects.

[0048] In some embodiments, the intermediate structure reinforcement layer 3 is a basalt fiber reinforced rubber layer; the fire-resistant flame retardant layer 4 is an aluminum silicate fire-resistant flame retardant layer; and the inner core layer 1 is a polyurethane foam core layer. The basalt fiber reinforced rubber layer is a basalt fiber reinforced structure based on rubber. The basalt fiber reinforced rubber layer has sealing, impact resistance and high temperature resistance. The fire-resistant flame retardant layer 4 is the outermost structure, which adopts an aluminum silicate fire-resistant flame retardant layer. The aluminum silicate fire-resistant flame retardant layer has excellent high temperature resistance. Laying it on the outermost layer can avoid direct contact between the basalt fiber reinforced rubber layer and the flame. The polyurethane foam core layer has the advantages of light weight, impact resistance, low cost, shape memory, etc.

[0049] This embodiment adopts basalt fiber reinforced rubber layer and aluminum silicate fire-resistant flame retardant layer to make the protective structure have good protective properties. The embodiment of the present invention adopts polyurethane foam core layer as inner core layer 1 to support the basalt fiber reinforced rubber layer and aluminum silicate fire-resistant flame retardant layer in the unfolded state. Specifically, since the polyurethane foam core layer has shape memory characteristics, after a certain period of time after the curtain-like body 100 is released, the polyurethane foam core layer can return to its original state, that is, the expanded state to support the basalt fiber reinforced rubber layer and the aluminum silicate fire-resistant flame retardant layer, and the polyurethane foam can be folded and stored to reduce the space occupied by the curtain-like body 100 after being folded, thereby facilitating the storage of the curtain-like body 100 in the folded state.

[0050] In some embodiments, such as Fig. 9 As shown, the inner core layer 1 is provided with ventilation channels 1-3 penetrating through two opposite sides thereof.

[0051] This embodiment facilitates that after the curtain-like body 100 is released, air enters the inner core layer 1 from the ventilation channels 1-3 to help the inner core layer 1 quickly recover to an expanded state. It is understandable that the curtain-like body 100 needs to be provided with holes connected to the space where the inner core layer 1 is located to facilitate the entry and exit of air or other gases.

[0052] In some embodiments, a plurality of ventilation channels 1 - 3 are arranged in parallel and at intervals, a rigid ventilation tube 2 is arranged in the ventilation channels 1 - 3 , and a plurality of ventilation holes are opened on the ventilation tube 2 .

[0053] The ventilation tube 2 in this embodiment helps to support the ventilation channels 1-3 to avoid blockage of the ventilation channels 1-3. In addition, the ventilation holes are provided to facilitate uniform expansion and contraction of the inner core layer 1.

[0054] The ventilation pipe 2 is preferably a metal thin-walled circular tube. The metal thin-walled circular tube can be made of metal materials such as aluminum and steel according to the requirements of tanks of different sizes. The metal thin-walled circular tube has excellent energy absorption capacity and performs well in the applications of explosion impact protection and fragment impact protection. At the same time, compared with solid metal rods of the same mass, the metal thin-walled circular tube structure has a higher bending modulus and can better support the overall protection structure.

[0055] In some embodiments, such as Fig.11 As shown, multiple sections of ventilation pipes 2 are arranged in each ventilation channel 1-3; there is a gap between two adjacent ventilation pipes 2 in each ventilation channel 1-3; and the gaps in all ventilation channels 1-3 are aligned.

[0056] This embodiment helps to achieve the horizontal folding of the curtain-like body 100 to further reduce the space occupied in the folded state. During preparation, the multiple ventilation tubes 2 are inserted into the ventilation channels 1-3 in sections, and the disconnected positions (i.e. the above-mentioned intervals) facilitate the folding and storage of the curtain-like body 100, and the excess parts are trimmed after insertion.

[0057] In some embodiments, the inner core layer 1 is a compressible foam material which is initially in an expanded state and has a shape memory function, such as polyurethane foam, and the inner core layer 1 is divided into two layers along the thickness direction, namely an upper layer 1-1 and a lower layer 1-2; the bottom surface of the upper layer 1-1 and the top surface of the lower layer 1-2 are sinusoidal corrugated surfaces, and the shapes of the two sinusoidal corrugated surfaces are complementary, that is, the groove structure of one sinusoidal corrugated surface is opposite to the convex structure of the other sinusoidal corrugated surface, and the convex structure and the groove structure are the same in shape and size, and ventilation channels 1-3 are provided in both the upper layer 1-1 and the lower layer 1-2.

[0058] The upper layer 1-1 and the lower layer 1-2 in this embodiment use sinusoidal corrugated boundaries to increase the foam expansion speed.

[0059] In some embodiments, such as Fig. 9 As shown, the inner core layer 1 is a grid-like structure as a whole.

[0060] This embodiment adopts a grid-shaped structure to improve the structural rigidity after the foam expands and to better play a supporting role.

[0061] In some embodiments, a hook ring 4 - 3 is provided at the bottom of the curtain-like body 100 , and the hook ring 4 - 3 can be detachably disposed on the ground around the energy storage tank.

[0062] This embodiment facilitates fast fixing of the bottom of the curtain-like body 100 .

[0063] In some embodiments, the inner core layer 1 in a contracted state can be ventilated to reach an expanded state, and the inner core layer 1 in an expanded state can be evacuated to reach a contracted state; a closed interlayer is formed inside the intermediate structure reinforcement layer 3, and the inner core layer 1 is placed in the closed interlayer; the intermediate structure reinforcement layer 3 is provided with a ventilation valve port 3-2 connected to the closed interlayer, and two ventilation valve ports 3-2 are provided, and the ventilation valve ports 3-2 are normally closed and opened when air needs to be in or out.

[0064] When the present embodiment is used, air can be pumped into the closed interlayer from one or both of the vent valve ports 3-2 by an air intake device, such as an air pump, to help the inner core layer 1 quickly recover to an expanded state. It can be understood that there are many ways of use, and air can be supplied to the closed interlayer through only one of the vent valve ports 3-2, and the other one can be used to exhaust air to prevent damage to the device due to excessive pressure in the closed interlayer.

[0065] In some embodiments, the embodiments of the present invention further include a storage assembly 200; the storage assembly 200 is fixedly disposed on the top of the energy storage tank; the storage assembly 200 is used to store the curtain-like body 100 in a folded state.

[0066] Since the curtain-like body 100 is normally in a folded state, i.e., a non-use state, the duration of this state is uncertain and may not be opened for several years. Based on this, in order to reduce the number of maintenance times, the storage assembly 200 in this embodiment is used to protect the curtain-like body 100 in the non-use state.

[0067] In some embodiments, the storage assembly 200 includes a protective cover assembly 5 and a protective base 6; the protective cover assembly 5 is located above the protective base 6, the inner side of the protective cover assembly 5 is fixedly arranged on the top of the energy storage tank, and the outer side of the protective cover assembly 5 extends toward the outer side of the cylindrical surface where the outer wall of the energy storage tank is located; the protective base 6 includes a connecting bracket 6-1, a storage cover 6-3 and a strap 6-4; the connecting bracket 6-1 is fixedly connected to a part of the structure close to the inner side of the protective cover assembly 5; the top of the curtain-shaped body 100 is fixedly connected to the connecting bracket 6-1 or the protective cover assembly 5, one end of the storage cover 6-3 is fixedly connected to the connecting bracket 6-1, and the other end of the storage cover 6-3 is fixedly connected to the connecting bracket 6-1, and the other end of the storage cover 6-3 is fixedly connected to the connecting bracket 6-1. The end is connected with a strap 6-4; the part of the structure of the protective cover assembly 5 close to the outside is fixedly provided with a remote control unhooking device 5-4, and the storage assembly 200 has a storage state and a release state. In the storage state, the strap 6-4 is hooked by the remote control unhooking device 5-4, and a storage space is formed between the protective base 6 and the protective cover assembly 5, and the storage space contains the curtain-like body 100 in the folded state; in the release state, the remote control unhooking device 5-4 loosens the strap 6-4, and the storage cover 6-3 opens downward under the gravity of the curtain-like body 100, and the bottom end of the curtain-like body 100 droops from the side of the energy storage tank under the gravity. The remote control unhooking device 5-4 is preferably a remote control electric unhooking device.

[0068] Specifically, the strap 6-4 is provided with a round hole, which is used in conjunction with the remote control unhooking device 5-4, that is, the hook of the remote control unhooking device 5-4 is hooked on the round hole of the strap 6-4. When unhooking is required, the remote control unhooking device 5-4 controls the hook to rotate or move to release the strap 6-4.

[0069] The storage cover 6-3 can be made of waterproof nylon, and of course, can also be made of other flexible materials with protective capabilities.

[0070] This embodiment realizes remote release of the curtain-like body 100 by remote control.

[0071] In some embodiments, such as Figure 14-15 As shown, the protective cover assembly 5 includes a protective cover body 5-1, a protective cover base 5-2 and a bottom support connection port 5-3; the protective cover body 5-1, the protective cover base 5-2 and the bottom support connection port 5-3 are all made of metal, such as steel, and the protective cover base 5-2 is fixed to the top of the energy storage tank by bolts or welding, and the bottom support connection port 5-3 and the protective cover body 5-1 are both fixedly arranged on the protective cover base 5-2, and the bottom support connection port 5-3 is located below the protective cover body 5-1.

[0072] like Figure 16-17As shown, the protective base support 6 includes a connecting support 6-1, a curtain-like body connecting port 6-2, a storage cover 6-3 and a binding strap 6-4, one end of the connecting support 6-1 is inserted into the base support connecting port 5-3 and fixedly connected by bolts, the curtain-like body connecting port 6-2 is fixedly connected to the connecting support 6-1, and the top of the curtain-like body 100 is inserted into the curtain-like body connecting port 6-2 and fixedly connected by bolts or other fasteners.

[0073] This specification also provides a preparation method of the polyurethane foam core layer, the aluminum silicate fire-resistant and flame-retardant layer, and the basalt fiber reinforced rubber layer mentioned in the above embodiments.

[0074] Polyurethane foam core layer: It is prepared by uniformly mixing dry polyethylene glycol and polyimide aerogel, tin catalyst, foam stabilizer, amine catalyst, foaming agent and flame retardant, etc. It has certain flame retardancy and excellent compression rate and resilience.

[0075] Basalt fiber reinforced rubber layer: Use a cutting machine to cut the basalt fiber woven bare cloth of appropriate size, then use an ultrasonic machine to clean it with alcohol for 30 minutes to remove impurities such as oil on the surface, and put the cleaned basalt fiber woven bare cloth into an oven for drying. Soak the basalt fiber woven bare cloth in maleic anhydride, diisopropylbenzene peroxide, acetone, and polyurethane emulsion, and then combine it with the rubber base. Repeat this step according to the number of layers required for preparing the sample and stack it. Put the inner core layer into the prepared basalt fiber reinforced rubber layer, use the ventilation valve ports 3-2 on both sides to extract the internal air, and then use the single-side ventilation valve port 3-2 to blow in the gas after extraction. At this time, the other ventilation valve port 3-2 is naturally opened. In this way, the air extraction and air intake cycle is repeated twice, and the foam has shape memory characteristics. Such operation steps can test the foam expansion ability and avoid the long delay of the initial expansion of the foam.

[0076] Aluminum silicate fire-resistant flame-retardant layer: It is prepared by mixing hard refractory clay powder with alumina, silicon powder, chromium oxide, silicon nitride and other materials, and spinning with a spinning machine. The aluminum silicate fire-resistant flame-retardant layer can withstand high temperature environments above 1000 degrees Celsius, has good stability, strong tensile strength, and a long service life. The prepared aluminum silicate fire-resistant flame-retardant layer is laid and fixed on the basalt fiber reinforced rubber layer to prevent the basalt fiber reinforced rubber layer from direct contact with the flame.

[0077] The present invention also provides a flexible arresting emergency protection system, such as Figure 6 As shown, it includes four flexible arresting emergency protection structures as described above, and the four flexible arresting emergency protection structures can be surrounded on all sides of the energy storage tank.

[0078] In some embodiments, a hook 4-3 is provided at the bottom of the curtain-shaped body 100, and the hook 4-3 can be detachably provided on the ground around the energy storage tank; the hook 4-3 is an eye-shaped rotating hook, and the ground around the energy storage tank is preset with ground threaded holes, which are divided into multiple groups, and the distance between each group of ground threaded holes and the energy storage tank is different. Specifically, the ground threaded holes are threaded holes of M30 or above, and the hook 4-3 is set as an eye-shaped rotating hook of M30 or above.

[0079] In this embodiment, the tension of the curtain-like body 100 can be adjusted by adjusting the connection position between the hook ring 4 - 3 and the ground.

[0080] The present invention also provides a flexible arresting emergency protection method, comprising:

[0081] The curtain-like body 100 is switched from a folded state to an unfolded state; the curtain-like body 100 in the unfolded state is laid on the side of the energy storage tank.

[0082] The preparation and installation method of the flexible blocking emergency protection structure provided by the present invention is as follows:

[0083] Step 1: Use a cutting machine to cut the basalt fiber woven bare cloth into a suitable size, then use an ultrasonic machine to clean it with alcohol for 30 minutes to remove impurities such as oil on the surface, and then put the cleaned basalt fiber woven bare cloth into an oven for drying;

[0084] Step 2: soak the basalt fiber woven bare cloth in maleic anhydride, diisopropylbenzene peroxide, acetone, and polyurethane emulsion, and then combine it with the rubber substrate. Repeat this step and stack it according to the number of layers required for preparing the sample to complete the preparation of the basalt fiber reinforced rubber layer.

[0085] Step 3: Check the sealing performance of the basalt fiber reinforced rubber layer and install the vent valve port 3-2;

[0086] Step 4: Cut two layers of foam core layers with sinusoidal corrugated surfaces, namely the upper layer and the lower layer, and buckle them to form a polyurethane foam core layer. Insert the metal thin-walled circular tubes into the ventilation channels 1-3 in sections, and cut off the excess parts;

[0087] Step 5: Place the polyurethane foam core layer into the basalt fiber reinforced rubber layer and heat press the edges to seal;

[0088] Step 6: Use the ventilation valve ports 3-2 on both sides to extract the internal air, and then use the ventilation valve port 3-2 on one side to blow in the air. At this time, the other ventilation valve port 3-2 opens naturally. In this way, the air extraction and air intake cycle is repeated twice. The polyurethane foam core layer has shape memory characteristics. This operation step can test the foam expansion ability and avoid a long delay in the initial expansion of the foam.

[0089] Step 7: bonding the aluminum silicate fire-resistant and flame-retardant layer on the surface of the basalt fiber reinforced rubber layer;

[0090] Step 8: Connect the curtain-like body 100 to the protective base 6, use the ventilation valves 3-2 on both sides to extract the air inside the basalt fiber reinforced rubber layer to shrink / compress the polyurethane foam core layer, close the ventilation valves 3-2 on both sides, and fold and roll up;

[0091] Step nine, installing the protective cover assembly 5 on the top of the energy storage tank;

[0092] Step 10: Connect the protective base 6 to the protective cover assembly 5, fix the strap 6-4, and complete the installation.

[0093] Steps for emergency use:

[0094] Step 1: When an emergency occurs, the remote control electric release device is opened by remote control, and the curtain-like body 100 is naturally spread downward;

[0095] Step 2: The ground staff opens the ventilation valve ports 3-2 on both sides, connects the air intake device to the ventilation valve port 3-2 on one side, and opens the other end naturally to allow the polyurethane foam core layer to expand;

[0096] Step 3: Disconnect the air intake device, keep the vent valve port 3-2 open, and install the hook ring 4-3 in the threaded hole on the ground to complete the emergency installation;

[0097] Step 4: After use, check whether each flexible barrier emergency protection structure is damaged and the degree of damage, and replace or repair damaged accessories, such as the storage component 200, hook ring 4-3 and curtain-like body 100, and then evacuate the curtain-like body 100, fold it, roll it up and put it into the storage component 200 for next use.

[0098] In order to facilitate understanding of the above embodiments, the following description is made:

[0099] The present invention takes the actual situation that ground energy storage tanks are repeatedly hit and energy storage tanks explode and leak from time to time in modern warfare as the engineering background, and designs a flexible blocking emergency protection structure that meets the high-temperature use environment of 1000 degrees Celsius, which can be used to intercept external impact fragments, resist the impact of the energy storage tank's own explosion, and intercept the splash of high-temperature fragments generated by its own explosion. Compared with the existing structure, it can achieve full-size protection of the side wall of the energy storage tank, can be pre-equipped, and can achieve rapid response and rapid equipment in emergency situations. Its structural design meets the protection function for the impact of high-temperature fragments generated by the explosion of drone ammunition, the fall of high-temperature fragments generated by the explosion of intercepted targets in the air, the impact of the energy storage tank's own explosion, and the splash of high-temperature fragments generated by its own explosion.
