[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] The following embodiments are described in detail with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims. In addition, the entire content of the structure represented by the following embodiments is not limited to the solution required as the invention described in the claims.

[0023] Please refer to the attached Figure 1-2 The rapid prototyping fire emergency rescue fluid dam provided in this embodiment includes a main body 1 having a hollow tube cavity 3 inside and auxiliary bodies 2 arranged parallel to both sides of the main body 1, such as Figure 1 As shown, the main body 1 is located in the middle, and auxiliary bodies 2 are arranged in parallel on the upper and lower sides thereof. The main body 1 and the two auxiliary bodies 2 are connected to form an integrated structure. The area, height and other specification parameters of the main body 1 and the auxiliary bodies 2 can be determined according to actual use requirements. The actual size of the fluid dam is determined in accordance with the requirements of the construction site to meet the application needs of firefighting emergency rescue. The hollow tube cavity 3 is used to contain fluid to support the main body 1. Both ends of the main body 1 are provided with a joint 4 connected to the hollow tube cavity 3 and a blind cover 5 detachably connected to the joint 4. The blind cover 5 is opened to inject or release the fluid through the joint 4. Each auxiliary body 2 is provided with a plurality of auxiliary body pockets 6 spaced apart along its length direction. Each auxiliary body pocket 6 is provided with a bag opening 7 for putting fillers into the auxiliary body pocket 6 and a tightening rope 8 for tightening the bag opening 7 on the side close to the main body 1. As shown Figure 2As shown, each auxiliary body pocket 6 is a three-dimensional square lattice pocket fixed on the auxiliary body 2, which is used to hold sand or other contents, and the bag opening 7 is decorated with a tightening rope 8, which is convenient for tying up the bag opening 7 to prevent the contents in the bag from leaking out. The size, number, spacing, etc. of the auxiliary body pocket 6 are determined according to actual use requirements. It should be noted that the "length direction" mentioned in the text refers to Figure 1 The rapid prototyping fire emergency rescue fluid dam shown in the figure is placed in a state, and the left and right directions in the figure are the length directions. In this way, the cover at one end of the main body is removed, and a fluid pump such as a water pump, an air pump or a slurry pump is used to connect the joint, and the fluid is injected into the hollow tube cavity to generate a certain outward pressure, prop up the main body, and then the cover is installed to prevent the fluid in the joint from overflowing and flowing out. Each auxiliary body pocket can be filled with sand or other contents and then the bag mouth is tied tightly, and the embankment or slope is covered by gravity. When in use, the device is quickly laid, the main body hollow tube cavity fluid is injected and the auxiliary body pocket is injected with fillers, so as to achieve safe and rapid prototyping, reduce the handling of sand and stone bags, save manpower, material resources and mechanical input, improve the speed and progress of construction operations, reduce the occurrence of danger, and have the advantages of safety and efficiency. In addition, it is spread out and laid flat on the ground, and a small amount of gas or other harmless fluid is filled into the hollow tube cavity to make the main body slightly bulge. People can lie on it and use it as a carrier for temporary rotation of workers participating in fire emergency rescue construction. It is safe, convenient, clean and hygienic. Or it can be lifted up and used as a tent, where people can take shelter temporarily, providing a better temporary resting place for the combatants and ensuring their safety and health, thus expanding the scope of use of the device and integrating multiple functions into one.

[0024] In this embodiment, the main body 1 and each auxiliary body 2 are made of soft materials. In this way, appropriate deformation can be made according to the application scenario, and the main body and the auxiliary body can be folded up to reduce the occupied space and facilitate placement and transportation. Optionally, the main body 1 is cylindrical and can be made into a bellows structure, which is convenient for shrinking, placement and stacking. Each auxiliary body 2 is rectangular and fixed on both sides of the main body 1.

[0025] In the preferred solution of this embodiment, each auxiliary body 2 is provided with a plurality of holes 9 spaced apart along the length direction thereof and used to fix the auxiliary body 2 on one side away from the main body 1, and each hole 9 is provided with a support ring 10 arranged around the circumference thereof. The support ring 10 is a metal ring die-cast at the hole 9, and the function of the hole of the ring is to pass through a fixed anchor or pile object rammed into the embankment or slope, so as to more firmly fix the auxiliary body and the main body so that they will not move by themselves.

[0026] like Figure 1As shown, the hollow tube cavity 3 is provided with a plurality of annular skeletons 11 which are spaced apart along the length direction of the main body 1 and matched with the hollow tube cavity 3. Specifically, each annular skeleton 11 is an annular fiber keel. In this way, the annular skeleton is equivalent to the inner diameter of the tube cavity, and plays a certain supporting and shaping role. When in use, the annular skeleton can prop up the main body in advance, which is convenient for injecting fluid, and can jointly withstand a certain pressure that disperses around or gathers inward. Both ends of the main body 1 are also provided with a conical transition section 12, and along the direction from close to the main body 1 to away from the main body 1, that is, along Figure 1 From the middle to the sides, the width of the tapered transition sections 12 on both sides gradually decreases, and the connector 4 is arranged at the end of the tapered transition section 12 away from the main body 1, that is, installed at the small end of the tapered transition section 12. This design is reasonable and convenient for installing the connector, so that the connecting pipeline can quickly transport the fluid to the hollow lumen. It should be noted that the "width direction" mentioned in the text refers to Figure 1 The shown rapid prototyping fire emergency rescue fluid dam is placed in a state where the up and down directions in the figure are the width directions. In addition, the joint 4 is provided with an external thread, and the cover 5 is provided with an internal thread matched with the external thread, which is convenient for quick disassembly and assembly through threaded connection.

[0027] Furthermore, one of the two joints 4 is provided with a one-way valve and the other is provided with a pressure relief valve. When fluid is injected into the hollow tube cavity 3, the one-way valve is turned on, and the pressure relief valve is used to maintain the pressure in the hollow tube cavity 3 at a set value. When the pressure in the hollow tube cavity 3 is higher than the set value, the pressure relief valve is opened to discharge the fluid. Specifically, Figure 1 As shown, a one-way valve is installed inside the left connector 4. When in use, open the blind covers 5 at both ends and inject fluid into the hollow tube cavity 3. At this time, the one-way valve is turned on, that is, the fluid can flow into the hollow tube cavity 3 from left to right as shown by the arrow. In the opposite direction, the one-way valve is cut off and the fluid cannot pass through. A pressure relief valve is installed inside the right connector 4. The pressure value is preset at the factory. This value can be determined according to the tolerance pressure of the main body 1. When the main tube cavity is under too much pressure, the pressure relief valve can be used to adjust the pressure relief. The fluid flows out of the tube cavity from left to right to ensure that the main tube cavity is not broken. When it drops to the set value, the pressure relief valve automatically closes and the fluid no longer flows out. After completing the fluid filling, tighten the blind cover on the connector to ensure that the fluid in the connector will not overflow and flow out by itself, thereby playing a secondary sealing role.

[0028] As an optional embodiment, the rapid prototyping fire emergency rescue fluid dam also includes a connecting collar for connecting the joints 4 on two adjacent main bodies 1, and both ends of the connecting collar are provided with threaded connection sections that match the external threads. The connecting collar is an existing mature product. When in use, open the cover 5, select a connecting collar that matches the specifications of the joint 4, and connect the two joints 4. In this way, multiple fluid dams can be connected according to the required length to meet different length requirements. In other words, in actual application, the following can be used: Figure 1The fluid dams shown are connected in series, and the fluid is injected into each main body lumen from left to right.

[0029] The rapid prototyping fire emergency rescue fluid dam provided in this embodiment includes a main body, an auxiliary body, a joint for fluid inlet and outlet, a cover, an annular fiber keel, etc. When in stock, the main body lumen can be contracted and placed and pressed like a bellows with the annular fiber keel, and the auxiliary body can also be folded up to save space. When in use, two people hold the joints at both ends to quickly pull the main body lumen and the folded auxiliary body apart in opposite directions, quickly inject the fluid into the main hollow lumen and inject sand and gravel into the auxiliary body pocket, so as to achieve safe and rapid prototyping, save manpower and material resources, etc. In addition, the construction workers can continue to stack more sand and gravel bags in the vacant part of the auxiliary body, and tamp wooden stakes into the holes on the edge of the auxiliary body to prevent displacement and further strengthen the embankment. After use, the pump body is connected to the joint of the main hollow lumen for suction, and the fluid in the hollow lumen can be discharged. After cleaning and drying, it can be recycled and reused, which has the advantages of safety, high efficiency, energy saving and environmental protection. At the same time, by laying it flat on the ground or standing it up as a multifunctional expansion of a tent, it can also provide a better temporary resting platform for combatants to ensure their safety and health.
