Description

Technical Field

[0001] The invention relates to the technical field of rescue devices, and in particular to an emergency rescue device for desert tourism. Background Art

[0002] Under the continuous action of wind, desert quicksand has strong fluidity and is prone to forming large-scale quicksand areas. The threat to humans and animals mainly lies in the difficulty of finding support points to save themselves after being trapped. In the process of rescuing people trapped in desert quicksand, since the shallow sand in the desert quicksand tends to run downwards, it is difficult to quickly and effectively prevent or slow down the quicksand from burying, swallowing and squeezing the trapped people. Rescue is difficult and the surrounding environment is harsh.

[0003] With the rise of desert tourism, the threat of quicksand that may occur during desert tourism must be taken seriously and resolved to ensure the safety of personnel and prevent the development of desert tourism from being hit by security issues.

[0004] At present, there is no emergency rescue device for desert quicksand, so an emergency rescue device for desert tourism is proposed. Summary of the Invention

[0005] The purpose of the present invention includes providing an emergency rescue device for desert tourism that can at least provide a support platform for self-rescue, can greatly reduce or prevent quicksand from burying and further squeezing trapped people, and is easy to carry with a vehicle.

[0006] In order to achieve the above object, the present invention has the following technical solutions:

[0007] The present invention provides an emergency rescue device for desert tourism, comprising a core tube, an outer tube slidably sleeved on the outside of the core tube, at least three support rods and a cloth.

[0008] The support rods are evenly connected to the outer wall of the outer cylinder at the same height through their lower ends;

[0009] The shape of the apron is an inverted hollow cone, and the apron is wrapped around the outside of the support rod.

[0010] Preferably, the lower end of the support rod is hinged to the outer wall of the outer tube, a positioning piece is hinged to the middle of the support rod, and / or the upper end of the support rod is detachably connected to a support frame.

[0011] Preferably, the support frame is a circular or regular polygonal hard frame.

[0012] Preferably, the support frame is connected to the upper end of the support rod by hand-tightened bolts.

[0013] Preferably, the hand-tightened bolt is rotatably connected to the support frame, or is connected to the support frame or the support pole via a rope to prevent loss.

[0014] Preferably, the positioning member includes an end slot support rod and a tension spring, wherein the end slot support rod is a rigid rod having a groove at the bottom of one end for clamping the upper edge of the outer cylinder and a hole at the other end for rotating the connecting support rod; the tension spring is connected between the bottom of the end slot support rod and the top of the support rod.

[0015] Preferably, a convex edge is connected to the middle portion of the outer side of the peripheral wall of the core barrel.

[0016] Preferably, the convex edge is in the shape of a hollow frustum.

[0017] Preferably, the upper portion of the support rod is bent upward.

[0018] Preferably, an airbag is provided on the peripheral wall of the apron, and the airbag is sleeved on the outside of the apron, or fixedly connected to the outside of the apron by bonding or other means.

[0019] Preferably, a ladder is connected to the outside of the outer cylinder, and the ladder includes a vertical rod with a lower end vertically connected to the upper part of the outer surface of the outer cylinder, and a grab bar connected to the vertical rod in parallel at intervals.

[0020] Preferably, the ladder is detachably connected to the outer cylinder.

[0021] Preferably, the grab bar is a hollow ring.

[0022] Preferably, the number of the vertical rods is 3.

[0023] Preferably, the apron is made of nylon cloth.

[0024] Preferably, the core cylinder and the outer cylinder are both made of aluminum alloy or engineering plastics.

[0025] Preferably, a pull rope is connected to the grab bar and / or the support frame.

[0026] Due to the adoption of the above technical solution, the advantages of the present invention are:

[0027] 1. The present invention can protect the trapped person in time, prevent the quicksand from further burying and squeezing the trapped person, buy precious time for self-rescue and the next rescue, and also create a rescue support platform and tools.

[0028] 2. The core tube and outer tube provided by the present invention are slidable. During the continuous collapse of quicksand and the falling of the trapped person, the core tube can slide down under the action of its own gravity and / or by the trapped person pulling it down manually, thereby achieving greater protection for the trapped person within the present invention and reducing or avoiding the first aid device being lifted up by the upper part of the device due to quicksand flowing into the sand pit or the sinking of the trapped person away from the trapped person.

[0029] 3. The present invention is funnel-shaped as a whole, and the upwardly curved support rods at the upper part form a retaining edge effect with the surrounding cloth, so that the quicksand that slides into the shallow sand around the sand pit can easily flow into and gather under the surrounding cloth, so that the upper part of the present invention is relatively supported by the quicksand, which not only has a good anti-sinking effect, but also has a certain floating effect, and can provide a reliable support implementation platform and auxiliary pulling tools for rescue.

[0030] 4. The trapped person can pull or hold the upper edge of the outer tube and grab the pole to rescue himself. The rescuer can also stand on the pole and / or the positioning piece and the cloth to actively rescue the trapped person with the help of the ladder. In addition, the ladder is detachable and can be removed in time as needed to increase the rescue operation space.

[0031] 5. The present invention can be conveniently folded, easily carried in a vehicle, simple and quick to use, and has good effects. It is particularly suitable for providing emergency rescue for people trapped in quicksand during desert tourism.

[0032] 6. The present invention can also be connected with a pull rope to allow rescue workers to carry out emergency rescue far away from the collapsed area. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention provides an emergency rescue device 100 for desert tourism, see Figure 1 、 Figure 2 , including a core tube 10, an outer tube 20 slidably sleeved on the outside of the core tube 10, four support rods 30, a positioning member 40, a ladder 50, a cloth 3 and a support frame 60,

[0045] The lower ends of the support rods 30 are evenly connected to the outer wall of the outer cylinder 20;

[0046] One end of the positioning member 40 is rotatably connected to the middle portion of the support rod 30;

[0047] The ladder 50 is connected to the outer cylinder 20;

[0048] The support frame 60 is connected to the upper end of the support rod 30;

[0049] The shape of the apron 3 is an inverted hollow cone, and the apron 3 is wrapped around and bonded to the bottom of the support rod 30 .

[0050] The specific implementation method is now described as follows:

[0051] The core barrel 10 is cylindrical, with an outer convex ring on the upper end of the outer wall and a hollow truncated cone shaped convex edge 11 fixedly connected to the middle of the outer wall. Figure 3 、 Figure 4 .

[0052] The outer cylinder 20 is cylindrical with an inner diameter larger than the outer diameter of the outer convex ring. The lower end of the inner wall is provided with an inner convex ring to limit the outer convex ring so as to prevent the core cylinder 10 inserted therein from falling out. The lower part of the outer wall is evenly fixed with a double-hole ear plate 21. Figure 3 、 Figure 4 .

[0053] There are four support rods 30, each of which has a screw hole 31 at its upper end, an upwardly curved upper portion, an ear plate 32 at its middle portion, and a hole at its lower end. The lower ends of the four support rods 30 are evenly connected to the double-hole ear plate 21 on the outer wall of the outer cylinder 20 through the shaft 1. Figure 3 、 Figure 4 .

[0054] The positioning member 40 includes an end slot support rod 41 and a tension spring 2. The end slot support rod 41 is a straight rod with a groove 42 at one end for clamping the upper edge of the outer cylinder 20 and a hole at the other end for connecting the ear plate 32 through the shaft 1. The tension spring 2 is connected between the lower side of the end slot support rod 41 and the upper side of the support rod 30. Figure 3 、 Figure 4 、 Figure 6 .

[0055] The ladder 50 includes three vertical rods 52 whose lower ends are vertically connected to the upper portion of the outer surface of the outer cylinder 20, and two grab bars 51 connected to the vertical rods 52 in parallel at intervals. Figure 1 、 Figure 2 、 Figure 3 .

[0056] The support frame 60 is a regular quadrilateral rigid frame, and the support frame 60 is connected to the upper end of the support rod 30 by means of hand-tightened bolts 4. Figure 1 、 Figure 2 .

[0057] In this embodiment, the grab bar 51 is a hollow ring; the apron 3 is made of nylon cloth; the core tube 10 and the outer tube 20 are both made of aluminum alloy or engineering plastic; and the hand-tightening bolt 4 is rotatably connected to the support frame 60.

[0058] The method of using the present invention:

[0059] S1. Expand and fix. Pull the upper end of the support rod 30 away from the ladder 50 until it stops (at this time, under the action of the tension spring 2, the groove 42 below the end groove support rod 41 is clamped into the upper edge of the outer tube 20). Then, connect the support frame 60 to the upper end of the support rod 30 with the hand-tightening bolt 4 (to further enhance the structural stability of the present invention). Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 ;

[0060] S2, connect and release, connect the pull rope to the grab bar 51 or the support frame 60 (the pull rope can be omitted if the sinking degree is small), put it into the sinking place and put the trapped object inside. Figure 7 ;

[0061] S3. Rescue: If the person is not deeply buried and is conscious and has sufficient strength, he or she can pull or support the upper edge of the outer cylinder 20 or grab the pole 51 to free himself or herself. If the person is deeply buried and has no strength left, the rescuers can try to stand on the cloth 3 one by one to rescue him or her, ensuring that there is no further sinking. (If the person has the ability to rescue himself or herself with the help of the present invention, it is not recommended to step on someone else unless necessary.)

[0062] During the rescue process, it is recommended that both the trapped persons and rescuers wear safety ropes, and that the other end of the ropes be held by a designated person or connected to a fixed object such as a vehicle to prevent sudden accidental collapse. At the same time, other rescuers can also provide assistance by pulling the ropes.

[0063] S4. Folding and storage: After the person is free, pull the present invention out of the sand pit, unscrew the hand screw 4 and remove the support frame 60 from the support rod 30 (the support frame is stored separately nearby). Then, lift the groove 42 end of the end groove support rod 41 with one hand to make the groove 42 come out of the upper edge of the outer tube 20. Use the other hand to push the corresponding support rod 30 to turn the support rod 30 to a vertical position and fold it. For easier transportation, the folded present invention can be further tied axially and radially with ropes.
