Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and in particular to a convenient high-altitude rescue receiving network. Background Technology

[0002] With the acceleration of urbanization, the number of high-rise buildings, bridges, tunnels, power transmission towers, and other high-altitude facilities has surged, leading to frequent safety accidents such as falls from heights, accidental falls, and being stranded at heights due to extreme weather. Traditional rescue methods (such as ladder trucks and rope rescue) are greatly limited by terrain, have long response cycles, and are prone to causing secondary injuries to trapped individuals in complex environments. At the same time, the demand for "rapid response, safety protection, and efficient rescue" in urban emergency rescue systems is becoming increasingly urgent. As a low-cost, easy-to-deploy, and quickly-establishable passive protection and rescue equipment, high-altitude rescue networks have emerged and become one of the indispensable key pieces of equipment in modern emergency rescue systems.

[0003] In the prior art, a Chinese utility model patent with patent application number CN201920192331.8 discloses a portable high-altitude rescue receiving net. It mainly uses a crossbeam, a lower support rod, and an upper support rod to form a support structure with the wall, which is used to support and fix the receiving net installed on two mounting rods. Thus, the rescue net can be set up on the first to third floors below the incident floor, and the portable high-altitude rescue receiving net can be set up quickly for rapid rescue.

[0004] However, the above technology is only applicable to rescuing people who happen to be above houses with windows or balconies. If there are no windows or balconies directly below the person to be rescued, the rescue cannot be carried out, and the application scenarios are limited.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes a convenient high-altitude rescue receiving network, which aims to rescue people not only from windows or balconies of houses, but also from the ground.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A convenient high-altitude rescue receiving net includes a base composed of four detachable fixed plates and a rescue net device mounted on the upper part of the base. Each fixed plate has a caster wheel fixedly installed at its bottom. The rescue net device includes three first telescopic support rods, one second telescopic support rod, four telescopic structures, and a receiving net. The upper ends of the first and second telescopic support rods are detachably mounted with connecting posts. The three first and second telescopic support rods are respectively mounted on the upper ends of the four fixed plates. The lower end of the second telescopic support rod is rotatably connected to the upper end of the corresponding fixed plate, allowing the rescue net device to rotate around the first telescopic support rod. The four telescopic structures are respectively located between every two adjacent connecting posts, and the two ends of the telescopic structure in the telescopic direction are respectively fixedly connected to the upper ends of the two adjacent connecting posts. The four sides of the receiving net are respectively fixedly mounted on one end of the four telescopic structures. The four telescopic structures expand or retract to coordinate with the expansion or retraction of the receiving net.

[0009] Preferably, the telescopic structure includes multiple cross components, each cross component consisting of two cross-pivoted support rods, and the multiple cross components are connected in sequence to form the telescopic structure, with each pair of adjacent cross components being pivotally connected to each other.

[0010] Preferably, the telescopic structure is further provided with multiple telescopic drive components, one end of each cross component is fixedly connected to a third telescopic support rod, the multiple telescopic drive components are evenly arranged in a square along the length of the telescopic structure, and the two ends of each telescopic drive component are rotatably connected to a pair of adjacent third telescopic support rods.

[0011] Preferably, the telescopic drive component is an electric telescopic rod.

[0012] Preferably, a telescopic reinforcing rod can be detachably connected between each pair of adjacent connecting columns.

[0013] Preferably, each pair of adjacent connecting columns is fixedly installed with a fixing seat and a support seat. The fixing column has a fixing groove at the end near the lock support seat, and the support seat has a through hole corresponding to the fixing groove. The end of the support seat away from the lock fixing seat is detachably connected to the baffle. When installing the telescopic reinforcing rod, one end of the telescopic reinforcing rod passes through the through hole and inserts into the fixing groove, abutting against the bottom of the fixing groove, so that the other end of the telescopic reinforcing rod is in the through hole. The baffle is fixedly installed on the column fixing so that the reinforcing rod abuts against the baffle.

[0014] Preferably, the first telescopic support rod is movably fitted with a buffer block.

[0015] Preferably, the upper end of the base is provided with a connecting plate, each of the fixing plates is provided with a fixing hole, the connecting plate is provided with a connecting hole corresponding to the fixing hole, and the connecting plate is fixedly connected to the fixing plate through the connecting hole and the fixing hole.

[0016] Preferably, the upper end of the connecting plate is provided with a rotating seat, the rotating seat is rotatably connected to the connecting plate, the upper end of the rotating seat is fixedly connected to a limiting block, the limiting block is provided with a limiting hole, and a fourth telescopic support rod for fixing to the wall is installed in the limiting hole.

[0017] Preferably, the receiving net comprises multiple braided ropes, which are made of a blend of carbon fiber and liquid crystal polyaramid fiber.

[0018] The beneficial effects of this utility model are:

[0019] The technical solution of this utility model involves installing four first telescopic support rods on four fixed plates respectively. The support rods can be moved by universal wheels at the lower end of the fixed plates. The receiving net is supported by the telescopic structure installed between the first telescopic support rods, and the first telescopic support rods are also supported. By moving the distance between the first telescopic rods, the contraction and expansion of the telescopic structure are controlled, thereby controlling the receiving area of ​​the receiving net.

[0020] When used for ground-based rescue operations, the high-altitude rescue receiving net is pushed to a suitable location. Then, the four fixed plates are released from their fixed state, and the first telescopic support rod is pushed to separate the four fixed plates. As the first telescopic support rod moves, it drives the four telescopic structures to unfold, thereby unfolding the receiving net and expanding its receiving area to catch the person about to fall. The operation is simple and convenient, and rescue operations can be carried out quickly.

[0021] Furthermore, when used for rescuing people above from inside a room, the telescopic structure allows the rescue net device to be opened to a suitable size, making it suitable for windows or balconies of different sizes. By separating the three first telescopic support rods from their corresponding connecting columns, and then rotating the entire rescue net device to a suitable angle via the second telescopic support, the rescue net device extends out of the window or balcony. The wall of the window or balcony holds the rescue net device in place. Then, the three first telescopic support rods are stretched to the top of the house and abut against the wall, fixing the base in place. Thus, when using this invention for high-rise rescues, a rescue net can be quickly erected on the first to third floors below the incident floor, reducing the impact on falling personnel and improving rescue efficiency.

[0022] The convenient high-altitude rescue receiving network of this utility model can be used for rescue from room windows or balconies, or for rescuing falling people from the ground. Attached Figure Description

[0031] The following will be combined with the appendix Figure 1 To be continued Figure 6 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] This embodiment proposes a convenient high-altitude rescue receiving network 5, such as... Figure 1 As shown, it includes a base that can be detachably assembled from four fixing plates 1 and a rescue net device installed on the upper part of the base.

[0033] Specifically, refer to Figure 1The four fixing plates 1 can be fixed together with screws to form a square plate base; alternatively, they can be spliced ​​together by snap-fit, allowing for quick installation and disassembly. Each fixing plate 1 has a caster wheel 8 fixedly installed at its bottom. Preferably, the caster wheel has a locking mechanism to lock it in place and prevent slippage. Preferably, the caster wheel 8 is constructed from a tracked chassis, which is driven by a motor. The tracked chassis increases the support area and enhances the stability of the overall structure.

[0034] Reference Figure 1 The rescue net device includes three first telescopic support rods 3, one second telescopic support rod 2, four telescopic structures 4, and a receiving net 5. The upper ends of both the first telescopic support rods 3 and 2 are detachably mounted with connecting posts 7 via screws. The three first telescopic support rods 3 and 2 are respectively mounted on the upper ends of four fixed plates 1, and the lower ends of the second telescopic support rods 2 are rotatably connected to the upper ends of their respective fixed plates 1, allowing the rescue net device to rotate around the first telescopic support rod 3. The four telescopic structures 4 are respectively located between every two adjacent connecting posts 7, and the two ends of each telescopic structure 4 in the telescopic direction are respectively fixedly connected to the upper ends of the corresponding two adjacent connecting posts 7 via screws. The four sides of the receiving net 5 are fixedly mounted to one end of each of the four telescopic structures 4 via screws or ropes. The four telescopic structures 4 expand or retract, thus coordinating the expansion or retraction of the receiving net 5, allowing the four sides of the receiving net 5 to expand and retract with the telescopic structures 4.

[0035] The upper end of the fixed plate 1 corresponding to the second telescopic support rod 2 is provided with a rotating groove, and the lower end of the second telescopic support rod 2 is embedded in the rotating groove and rotatably connected to the fixed plate.

[0036] In this embodiment, four first telescopic support rods 3 are respectively installed on four fixed plates 1. The support rods can be moved by the casters 8 at the lower end of the fixed plates 1. The receiving net 5 is supported by the telescopic structure 4 installed between the first telescopic support rods 3, and the first telescopic support rods 3 are also supported. By moving the distance between the first telescopic rods, the contraction and expansion of the telescopic structure 4 are controlled, thereby controlling the receiving area of ​​the receiving net 5. Thus, by pushing the high-altitude rescue receiving net 5 to a suitable position and then expanding the receiving net 5 through the telescopic structure 4, a rescue operation can be quickly launched on the ground.

[0037] When used for ground rescue, the high-altitude rescue receiving net 5 is pushed to a suitable location, and then the four fixed plates 1 are released from their fixed state. The first telescopic support rod 3 is pushed to separate the four fixed plates 1. As the first telescopic support rod 3 moves, it drives the four telescopic structures 4 to unfold, thereby unfolding the receiving net 5 and expanding the receiving area of ​​the receiving net 5 to catch the person about to fall. The operation is simple and convenient, and rescue operations can be carried out quickly.

[0038] Furthermore, referring to Figure 5 and Figure 6 When used for rescuing people from above inside a room, the telescopic structure 4 allows the rescue net device to be opened to a suitable size, making it suitable for windows or balconies of different sizes. By separating the three first telescopic support rods 3 from their corresponding connecting columns 7, and then rotating the entire rescue net device to a suitable angle through the second telescopic support, the rescue net device is extended outside the window or balcony. The wall 11 of the window or balcony holds the rescue net device in place. Then, the three first telescopic support rods 3 are stretched to the top of the house and abut against the wall to fix the base. Thus, when using this utility model for high-rise rescue, a rescue net can be quickly set up on the first to third floors below the incident floor, reducing the impact on the falling person and improving rescue efficiency.

[0039] In detail, the first telescopic support rod 3 and the second telescopic support rod 2 can be manually telescopic rods that are fixed by screws after being moved to a preset position; or they can be automatic telescopic rods with a drive structure, generally including electric telescopic rods, hydraulic telescopic rods, pneumatic telescopic rods, etc.

[0040] Among them, such as Figures 2 to 3 As shown, the telescopic structure 4 includes multiple cross components 41. Each cross component 41 consists of two cross-pivoted support rods 413. Multiple cross components 41 are connected in sequence to form the telescopic structure 4. Each pair of adjacent cross components 41 are pivotally connected to each other, so that each cross component 41 can work together.

[0041] To facilitate the opening and closing of the telescopic structure 4, such as Figure 2 As shown, the telescopic structure 4 is also provided with multiple telescopic drive components 412. One end of each cross component 41 is fixedly connected to a third telescopic support rod 411. The multiple telescopic drive components 412 are evenly arranged in a rectangular shape along the length of the telescopic structure 4, and the two ends of the telescopic drive components 412 are rotatably connected to a pair of adjacent third telescopic support rods 411.

[0042] The telescopic drive component 412 can be an electric telescopic rod, a hydraulic cylinder, a pneumatic cylinder, etc. The telescopic drive component 412 drives the telescopic structure 4 to expand or contract, thereby opening or closing the receiving net 5.

[0043] During the rescue operation, the supporting force of the telescopic structure 4 may be insufficient. (Refer to...) Figure 1 A telescopic reinforcing rod 6 is detachably connected between each pair of adjacent connecting columns 7 by screws. The telescopic reinforcing rod 6 can extend and retract with the telescopic structure 4.

[0044] Preferably, refer to Figure 1When it is necessary to increase the support force of the telescopic structure 4, in order to facilitate the installation of the telescopic reinforcement rod 6, a fixing seat 61 and a support seat 62 are fixedly installed on each of two adjacent connecting columns 7. The fixing column has a fixing groove at the end near the lock support seat 62, and the support seat 62 has a through hole corresponding to the fixing groove. The end of the support seat 62 away from the lock fixing seat 61 is detachably connected to the baffle 64. One end of the baffle 64 is rotatably connected to the support seat 62 by a hinge, and the other end is fixed to the support seat 62 by screws, thereby realizing the quick installation of the telescopic reinforcement rod 6. When installing the telescopic reinforcement rod 6, open the baffle 64, stretch the telescopic reinforcement rod 6 to a suitable length, then pass one end of the telescopic reinforcement rod 6 through the through hole and insert it into the fixing groove to abut against the bottom of the fixing groove, so that the other end of the telescopic reinforcement rod 6 is just in the through hole. Close the baffle 64 and fix it with screws.

[0045] Reference Figure 5 and Figure 6 When a rescue operation is carried out inside the room, the telescopic reinforcement rod 6 needs to be supported by the wall 11 of the window or balcony. During use, the telescopic reinforcement rod 6 will rub against the wall 11, which will damage the telescopic reinforcement rod 6 over time, resulting in insufficient support and making it easy to break during the rescue. Therefore, the first telescopic support rod 3 is movably fitted with a buffer block 63. The buffer block 63 is an elastic rubber block. The elastic rubber block separates the wall 11 from the telescopic reinforcement rod 6, thereby avoiding friction between the telescopic reinforcement rod 6 and the wall 11. The buffer block 63 also plays a buffering role for the telescopic reinforcement rod 6, increasing the durability of the telescopic reinforcement rod 6, and also reducing the impact force of the falling person on the overall structure.

[0046] like Figure 4 As shown, the upper end of the base is provided with a connecting plate 9, and the fixing plates 1 are fixed together by the connecting plate 9. Each fixing plate 1 is provided with a fixing hole, and the connecting plate 9 is provided with a connecting hole 91 corresponding to the fixing hole. The connecting plate 9 is fixedly connected to the fixing plate 1 through the connecting hole 91 and the fixing hole.

[0047] When conducting rescue operations inside the room, to further increase the overall structural support, preferably, the upper end of the connecting plate 9 is provided with a rotating seat 92. The rotating seat 92 is rotatably connected to the connecting plate 9 via a rotating groove and a rotating column. A limiting block 93 is fixedly connected to the upper end of the rotating seat 92. The limiting block 93 has a limiting hole 94, and a fourth telescopic support rod 10 for fixing to the wall is installed in the limiting hole 94. In use, the limiting block 93 is rotated to a suitable angle, and then the fourth telescopic support rod 10 is unfolded so that its two ends abut against the wall, and then fixed with screws. The fourth telescopic support rod 10 further strengthens the support for the rescue net device.

[0048] Optionally, the second telescopic support rod 2 and the first telescopic support rod 3 are respectively foldably connected to the fixed plate 1, so that the second telescopic support rod 2 and the first telescopic support rod 3 can be folded up for easy handling.

[0049] Preferably, the receiving net 5 comprises multiple braided ropes woven together. Specifically, the braided ropes are made of a mixture of carbon fiber and liquid crystal polyaramid fiber. The carbon fiber threads and liquid crystal polyaramid fiber are first woven into thin ropes, and then the carbon fiber ropes and liquid crystal polyaramid fiber ropes are woven together. The braided rope made of the mixture of carbon fiber and liquid crystal polyaramid fiber is lightweight and not easily broken, making it suitable for high-altitude rescue operations.

[0050] Optionally, a fifth telescopic support rod is provided at the upper end of the connecting column 7 connected to the second telescopic support rod 2. The fifth telescopic support rod is detachably connected to the connecting column 7 by screws. When carrying out rescue operations in the room, the fifth telescopic support rod is installed on the connecting column and extended to abut against the wall of the roof, thereby further increasing the overall support performance and making it more stable.

[0051] Among them, the first telescopic support rod, the second telescopic support rod, the third telescopic support rod, the fourth telescopic support rod, and the fifth telescopic support rod are all telescopic rods.

[0052] The technical solution of this utility model is to install four first telescopic support rods 3 on four fixed plates 1 respectively. The support rods can be moved by the universal wheels 8 at the lower end of the fixed plates 1. The receiving net 5 is supported by the telescopic structure 4 installed between the first telescopic support rods 3, and the first telescopic support rods 3 are also supported. By moving the distance between the first telescopic rods, the contraction and expansion of the telescopic structure 4 are controlled, thereby controlling the receiving area of ​​the receiving net 5.

[0053] When used for ground rescue, the high-altitude rescue receiving net 5 is pushed to a suitable location, and then the four fixed plates 1 are released from their fixed state. The first telescopic support rod 3 is pushed to separate the four fixed plates 1. As the first telescopic support rod 3 moves, it drives the four telescopic structures 4 to unfold, thereby unfolding the receiving net 5 and expanding the receiving area of ​​the receiving net 5 to catch the person about to fall. The operation is simple and convenient, and rescue operations can be carried out quickly.

[0054] Furthermore, when used for rescuing people above from inside a room, the telescopic structure 4 can be used to open the rescue net device to a suitable size, making it suitable for windows or balconies of different sizes. By separating the three first telescopic support rods 3 from the corresponding connecting columns 7, and then rotating the entire rescue net device to a suitable angle through the second telescopic support, the rescue net device is extended outside the window or balcony. The wall 11 of the window or balcony holds the rescue net device in place. Then, the three first telescopic support rods 3 are stretched to the top of the house and abut against the wall to fix the base. Thus, when using this utility model for high-rise rescue, a rescue net can be quickly set up on the first to third floors below the incident floor, reducing the impact force on the falling person and improving rescue efficiency.

[0055] The portable high-altitude rescue receiving network 5 of this utility model can be used for rescue from room windows or balconies, or for rescuing falling people from the ground.

[0056] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
