Description
Technical Field
[0001] This application relates to the technical field of water rescue, and particularly to a flood disaster refuge device for historical blocks in high-density old urban areas. Background Art
[0002] Flood disasters include two categories: flood disasters and rainwaterlogging disasters. The two often occur simultaneously or continuously in the same area, and sometimes it is difficult to accurately define them, so they are often collectively referred to as flood disasters. Among them, in urban flood disasters, the speed and efficiency of rescue operations are crucial. However, in urban environments, in many areas (such as high-density old urban areas), it is difficult to use large lifeboats due to narrow streets, busy traffic, and complex terrain. Generally, flood disaster refuge devices with strong mobility, rapid deployment, and adaptability to complex environments, such as lifebuoys and floating boards, are used to carry out flexible and rapid rescue operations.
[0003] However, there are still some defects in the existing flood disaster refuge devices during use: First, for existing refuge devices, such as lifebuoys, when wearing, the user needs to get into the lifebuoy. However, due to differences in human body shapes, it is easy to cause trouble in putting on and taking off the lifebuoy, affecting the rescue efficiency; Second, when the user moves in the water, the user needs to overcome the resistance of the water flow, and the refuge device cannot provide additional guiding force, thus increasing the physical labor loss of the user and affecting the rescue efficiency. Summary of the Invention
[0004] This application provides a flood disaster refuge device for historical blocks in high-density old urban areas, which has the advantages of being able to change its connection method to reduce the difficulty of wearing and improve the rescue efficiency, and at the same time being able to provide guiding force to overcome the water flow resistance, reduce human loss, and further improve the rescue efficiency, so as to solve the problems of troublesome putting on and taking off of the device and low rescue efficiency, as well as the problems of serious physical strength waste due to water flow resistance and low rescue efficiency.

[0011] By providing a movable mechanism composed of a movable arc rod, a movable rope and a movable plate, and movable arc rods meshing with the steering mechanism are arranged in both the left fixing member and the right fixing member. A movable rope is arranged in the floating airbag. A movable plate is arranged on one set of movable arc rods. When the user wears the device and moves in the water, the movable plate can be controlled to drive the movable arc rod and the movable rope to rotate, so as to realize the synchronous rotation of multiple sets of steering mechanisms, improve the freedom of movement of the device in the water, and enhance the convenience of the user's movement. In addition, because the movable mechanism is in a circular shape during use and simultaneously communicates with the left fixing member, the right fixing member and the floating airbag, the connection stability between the left fixing member and the right fixing member is effectively enhanced, and the left fixing member and the right fixing member are prevented from disengaging from the clamped state during use and causing rescue errors.
[0012] Furthermore, it further includes: A filtering member, a limiting ball is arranged at the top end of the filtering member, and the filtering member is movably clamped with the bottom end of the left fixing member or the right fixing member through the limiting ball. The filtering member is movably sleeved outside the steering mechanism, and filter holes are formed in the wall surface of the filtering member; By arranging the filtering member at the bottom ends of the left fixing member and the right fixing member, and the filtering member is sleeved outside the steering mechanism, it can effectively filter obstacles in the water, such as floating garbage, etc., to prevent it from affecting the working efficiency of the steering mechanism. At the same time, generally, the obstacles accumulate at the side position of the device, and the water absorption direction of the steering mechanism is vertically arranged, and the drainage direction is horizontally arranged, thereby further preventing it from affecting the working efficiency of the steering mechanism; A protection mechanism, protection mechanisms are arranged at the bottom ends of both the left fixing member and the right fixing member, and the protection mechanism is closer to the inner circle of the left fixing member and the right fixing member than the filtering member.

Since the protection mechanism is arranged between the filter element and the human body, it effectively protects the human body and prevents the water flow impact force generated by the steering mechanism from causing harm to the human body. At the same time, when the partition component is impacted by the water flow, it will be compressed, thereby pushing the connecting block to move between the two connecting seats, realizing the mutual clamping of the two protection mechanisms at the bottoms of the left fixing member and the right fixing member, further enhancing the connection stability between the left fixing member and the right fixing member, and preventing the left fixing member and the right fixing member from disengaging from the clamped state during use and causing rescue mistakes.

One left fixing member and one right fixing member form a fixing mechanism, and multiple floating airbags and multiple fixing mechanisms are connected end to end. When wearing the device, first release the clamped state of one group of left fixing members and right fixing members, then surround the strip-shaped device around the human body, and finally restore the clamped state of the group of left fixing members and right fixing members. Therefore, the wearing process is simple to operate, and there is no need to drill into the ring-shaped device during wearing, effectively improving the rescue efficiency.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] Embodiment 1, a flood disaster refuge device for a historical block in a high-density old city, such as Figures 1 - 6 , including a left fixing member 1a and a right fixing member 1b, which are movably clamped between the left fixing member 1a and the right fixing member 1b, and a left fixing member 1a and a right fixing member 1b form a fixing mechanism.
[0023] Such as Figures 1 - 5 , Figures 7 - 8 , one end of the floating airbag 2 is connected to the end of the left fixing member 1a, and the other end of the floating airbag 2 is connected to the end of the right fixing member 1b. The floating airbag 2 is made of wear-resistant rubber material, and a gas valve 20 is fixedly communicated with the bottom end of the floating airbag 2. The gas valve 20 can be used to fill gas into the floating airbag 2 to make the floating airbag 2 expand, so as to facilitate the floating airbag 2 to float in water for rescue. It should be noted that, such as Figure 6 , a clamping head is fixedly connected to the wall surface of the end of the left fixing member 1a connected to the floating airbag 2, and a clamping member is fixedly connected to the wall surface of the end of the right fixing member 1b connected to the floating airbag 2. The clamping head and the clamping member can be movably clamped. Thus, when the floating airbag 2 needs to be stored, the left fixing member 1a and the right fixing member 1b at both ends of the floating airbag 2 approach each other, so that the floating airbag 2 is compressed and folded, and then the left fixing member 1a and the right fixing member 1b are connected and fixed by the clamping head and the clamping member, thereby reducing the space volume of the floating airbag 2 and realizing the storage of the floating airbag 2.
[0024] Such as Figures 1 - 8, both ends of the floating airbag 2 are penetrated by connecting members 3, and the connecting members 3 are movably connected to the left fixing member 1a or the right fixing member 1b. The connecting members 3 are composed of long screws and bolts. By using the connecting members 3, the stable connection between the floating airbag 2 and the fixing mechanism can be realized, and it is also convenient to disassemble, install and replace the floating airbag 2 with the left fixing member 1a and the right fixing member 1b.
[0025] As Figure 1 , the number of groups of the fixing mechanisms is the same as the number of floating airbags 2, and the fixing mechanisms and the floating airbags 2 are arranged alternately. When all the fixing mechanisms are in the engaged state, the fixing mechanisms and the floating airbags 2 present a ring shape connected end to end. When one fixing mechanism is in the non-engaged state, the fixing mechanisms and the floating airbags 2 present a strip shape not connected end to end. Therefore, the distribution design of the fixing mechanisms and the floating airbags 2 can provide convenience for the user to put on and take off.
[0026] By changing the engagement state between one fixing mechanism, the refuge device composed of the fixing mechanism, the floating airbag 2 and the connecting member 3 can be simply put on and taken off. Specifically, first, release the engagement state of one of the fixing mechanisms, then surround the strip-shaped device around the human body, and finally restore the engagement state of this group of fixing mechanisms. There is no need for the user to drill into the ring-shaped device when wearing, effectively improving the rescue efficiency.
[0027] Embodiment 2, on the basis of Embodiment 1, the flood disaster refuge device further includes a steering mechanism 4. As Figures 1 - 5 , a group of steering mechanisms 4 are arranged in a group of fixing mechanisms. The number of a group of steering mechanisms 4 is two, and the two steering mechanisms 4 are symmetrically arranged inside the left fixing member 1a and inside the right fixing member 1b, and are used to provide a guiding force for the movement of the refuge device, so as to push the user of the wearing device forward, enabling the user to move a longer distance overcoming the water flow resistance under the same physical strength state, effectively improving the rescue efficiency.
[0028] As Figures 10 - 11The steering mechanism 4 includes a steering member 41, a threaded rod 42, a steering tube 43 and a water pump 44. A steering cavity is provided inside the left fixing member 1a and the right fixing member 1b, and the left fixing member 1a and the right fixing member 1b are movably connected with the steering member 41 through the steering cavity, laying a foundation for the steering mechanism 4 to rotate as a whole when subjected to external force. A threaded hole is provided in the middle of the steering member 41, and the steering member 41 is threadedly connected with the threaded rod 42 through the threaded hole. The user can rotate the threaded rod 42 forward or reversely to move the threaded rod 42 downward or upward. The bottom end of the steering member 41 is fixedly connected to the top end of the steering tube 43, and the steering tube 43 is located below the left fixing member 1a and the right fixing member 1b, so that the steering tube 43 can work below the left fixing member 1a and the right fixing member 1b to generate a guiding force on the left fixing member 1a and the right fixing member 1b. An L-shaped cavity is opened in the steering part, and the water absorption direction of the steering tube 43 is vertical, and the drainage direction of the steering tube 43 is horizontal, so that the steering tube 43 can absorb water from bottom to top and drain from front to back to realize the backward spray of water, thereby providing a continuous forward driving force for the device to push the user wearing the device forward, and a water pump 44 is fixedly embedded in the steering tube 43 at the bending position of the L-shaped cavity, and a button for controlling the opening and closing of the water pump 44 is provided at the top of the water pump 44, and the position of the button is connected to the threaded hole of the steering member 41, that is, the threaded rod 42 located in the steering member 41 can control the opening and closing of the water pump 44, specifically, when the threaded rod 42 rotates and moves downward until it conflicts with the button of the water pump 44, the water pump 44 is pressed to start, and when the threaded rod 42 rotates and moves upward until it does not conflict with the button of the water pump 44, the water pump 44 is released and closed.
[0029] Embodiment 3, based on embodiment 2, the flood disaster shelter equipment further includes a movable mechanism 5, such as Figures 1 - 5 A movable mechanism 5 is arranged inside the fixing mechanism and the floating airbag 2, and the movable mechanism 5 is closer to the inner circle of the fixing mechanism than the steering mechanism 4, and is used to control the synchronous rotation of multiple groups of steering mechanisms 4, thereby changing the direction of the driving force to enhance the convenience of users wearing the shelter equipment to move in the water.
[0030] like Figures 9 - 10, the movable mechanism 5 includes a movable arc rod 51, a movable rope 52 and a movable plate 53. Movable cavities are formed inside both the left fixing member 1a and the right fixing member 1b, and the left fixing member 1a and the right fixing member 1b are movably sleeved with the movable arc rod 51 through the movable cavities. The two movable arc rods 51 located within one fixing mechanism are in contact, and the fitting ends of the two movable arc rods 51 have opposite magnetic polarities, thereby helping the two movable arc rods 51 to be stably connected. The steering cavity is communicated with the movable cavity, and the middle part of the steering member 41 is engaged with the side wall of the movable arc rod 51. Thus, when the movable arc rod 51 rotates along the movable cavity, it can push the steering member 41 to rotate itself within the steering cavity. An arc cavity is formed inside the floating airbag 2, and the floating airbag 2 is movably sleeved with the movable rope 52 through the arc cavity. The two ends of the movable rope 52 are respectively fixedly connected to one movable arc rod 51. When the refuge device is in a strip shape, the two movable ropes 52 in one of the fixing mechanisms are in a split state. When the refuge device is in a circular shape, the two movable ropes 52 in the fixing mechanism are in a connected state under the action of magnetic attraction force. At this time, the two movable arc rods 51 and one movable rope 52 are alternately arranged and connected end to end, making the movable mechanism 5 in a circular shape. Thus, the movable mechanism 5 stably penetrates through the fixing mechanism and the floating airbag 2, effectively enhancing the connection stability between the left fixing member 1a and the right fixing member 1b, preventing the front and rear offsets of the left fixing member 1a and the right fixing member 1b during use and their disengagement from the clamped state, which may cause rescue errors. In addition, the rotation of the movable mechanism 5 can enable multiple groups of steering mechanisms 4 to rotate synchronously, so as to improve the freedom of movement of the device in water and enhance the convenience of movement of the user. An activity groove is formed inside one of the fixing mechanisms, and the bottom end of the activity groove is communicated with the top end of the movable cavity. The top ends of the two movable arc rods 51 located within one of the fixing mechanisms are both fixedly connected with a movable plate 53, and the movable plate 53 passes through the activity groove. The two movable plates 53 have opposite magnetic polarities, thereby enabling the two movable plates 53 to be stably connected and further improving the overall connection stability of the movable mechanism 5. When it is necessary to rotate the movable mechanism 5, the user can push the movable plate 53 to move along the activity groove. It should be noted that when the movable plate 53 moves from one end of the activity groove to the other end, the steering mechanism 4 can be rotated 360 degrees.
[0031] Embodiment 4. On the basis of Embodiment 2, the flood disaster refuge device further includes a filtering member 6, such as Figures 1 - 5 , Figure 12 , Figure 15 . A limiting ball is provided at the top end of the filtering member 6, and the filtering member 6 is movably clamped to the bottom end of the left fixing member 1a or the right fixing member 1b through the limiting ball, which facilitates the disassembly, installation and replacement of the filtering member 6 on the left fixing member 1a and the right fixing member 1b. The filtering member 6 is movably sleeved outside the steering mechanism 4. Specifically, the filtering member 6 is movably sleeved outside the steering tube 43, and filter holes are formed on the wall surface of the filtering member 6, which can filter obstacles in the water, such as floating garbage, etc., to prevent them from affecting the working efficiency of the steering mechanism 4.
[0032] Embodiment 5. On the basis of Embodiment 4, the flood disaster refuge equipment further includes a protection mechanism 7, such as Figures 1 - 5 , protection mechanisms 7 are provided at the bottom ends of the left fixing member 1a and the right fixing member 1b, and the protection mechanism 7 is closer to the inner ring of the left fixing member 1a and the right fixing member 1b than the filter member 6 for protecting the human body, such as Figures 12 - 15 , the protection mechanism 7 includes a connection seat 71, a partition component 8, a connection block 72 and a connection pipe 73, specifically: Two connection seats 71 are provided in one protection mechanism 7, and two protection mechanisms 7 are symmetrically provided on one fixing mechanism. A limit ball is provided at the top end of the connection seat 71, and the connection seat 71 is movably clamped with the bottom end of the left fixing member 1a or the right fixing member 1b through the limit ball, which is convenient for disassembling, installing and replacing the protection mechanism 7 on the left fixing member 1a and the right fixing member 1b.
[0033] A limit groove is opened at the top end of the connection seat 71, and the two connection seats 71 are connected through the limit groove with the partition component 8. The partition component 8 can effectively block the water flow impact force flowing towards the human body direction and reduce the injury of the human body. The partition component 8 includes a partition plate 81 and a partition membrane 82. The number of the partition plates 81 is two, and the partition plate 81 close to the filter member 6 is movably clamped with the connection seat 71, and the partition plate 81 far from the filter member 6 is fixedly clamped with the connection seat 71. The two partition plates 81 are fixedly connected through the partition membrane 82. Gas is filled inside the partition membrane 82, and the partition membrane 82 has elasticity. When the partition membrane 82 is not impacted by water flow, the movably arranged partition plate 81 moves towards the filter member 6 direction, and the partition membrane 82 extends. When the partition membrane 82 is impacted by water flow, the movably arranged partition plate 81 moves towards the direction away from the filter member 6, and the partition membrane 82 compresses, thereby providing a power condition for the mutual clamping of the two protection mechanisms 7.
[0034] There are two mutually attached connection seats 71 in one fixing mechanism, and the two connection seats 71 are located on different protection mechanisms 7, which can help to enhance the connection stability between the two protection mechanisms 7, and further help to enhance the connection stability between the left fixing member 1a and the right fixing member 1b. Connection grooves are opened at the top ends of the two mutually attached connection seats 71, and the connection seat 71 is movably clamped with the connection block 72 through the connection groove.
[0035] The inside of the connecting seat 71 is fitted with a connecting pipe 73. One end of the connecting pipe 73 is fixedly communicated with the partition membrane 82. The other end of the connecting pipe 73 extends into the connecting groove and is fixedly connected with the connecting block 72. A section of the connecting pipe 73 extending into the connecting groove has an elastic force. When the partition membrane 82 is compressed, the gas in the partition membrane 82 is transferred into the connecting pipe 73, causing the connecting pipe 73 to stretch, and then pushing the connecting block 72 to move between the two connecting seats 71, realizing the stable connection of the two connecting seats 71, effectively preventing the left fixing member 1a and the right fixing member 1b from moving horizontally and disengaging from the connection. When the partition membrane 82 is not compressed, the gas in the connecting pipe 73 is transferred back into the partition membrane 82, causing the connecting pipe 73 to contract, and then pushing the connecting block 72 to move back into the connecting groove of the original connecting seat 71, realizing the separation of the two connecting seats 71, providing help for the subsequent separation of the left fixing member 1a and the right fixing member 1b.
[0036] The working principle of the usage method of the present invention is as follows: When the user wears the device, first inflate the floating airbag 2, and then release the locked state of one set of the left fixing member 1a and the right fixing member 1b, so that the device changes from a circular shape to a strip shape. Then, surround the strip-shaped device around the human body. It should be noted that the fixing mechanism with the movable plate 53 is arranged in the front of the human body to facilitate the user to control the movable mechanism 5. Finally, restore the locked state of this set of the left fixing member 1a and the right fixing member 1b, so that the device changes from a strip shape to a circular shape, thus completing the wearing of the device. The wearing process is simple in operation, without the need to drill into the circular-shaped device during wearing, effectively improving the rescue efficiency.
[0037] When the user moves in the water, the user rotates the threaded rod 42 to start the water pump 44, so that the steering mechanism 4 can suck water from below and spray it backward, thereby providing continuous forward driving force for the device to push the user wearing the device forward. Furthermore, the user can move a longer distance by overcoming the water flow resistance in the same physical state, effectively improving the rescue efficiency. At the same time, the user can drive the movable mechanism 5 to rotate according to the moving path, thereby changing the spraying direction of the steering mechanism 4, improving the freedom of movement of the device in the water, enhancing the convenience of the user's movement, and further reducing the resistance of the user moving in different directions in the water. In addition, due to the magnetic suction design between the movable arc rods 51 and the fixed design between the movable arc rods 51 and the movable ropes 52, the movable mechanism 5 presents an overall stable circular design during use, further enhancing the connection stability between the left fixing member 1a and the right fixing member 1b, preventing the left fixing member 1a and the right fixing member 1b from disengaging from the locked state during use and causing rescue mistakes.
[0038] When the user moves in the water, the filter member 6 will filter the water entering the steering pipe 43 to prevent the obstacles in the water from affecting the operation of the steering mechanism 4.
[0039] When the user moves in water, the protection mechanism 7 will obstruct the water flow directed towards the human body, effectively protecting the human body and preventing the water flow impact force generated by the steering mechanism 4 from causing harm to the human body. At the same time, when the separation component 8 is impacted by the water flow, it will be compressed, thereby pushing the connecting block 72 to move between the two connecting seats 71, realizing the mutual engagement of the two protection mechanisms 7 located at the bottom ends of the left fixing member 1a and the right fixing member 1b, further enhancing the connection stability between the left fixing member 1a and the right fixing member 1b, and preventing the left fixing member 1a and the right fixing member 1b from disengaging from the clamped state during use and causing rescue failures.
[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
