Description

Technical Field

[0001] The utility model relates to the technical field of search and rescue net baskets, in particular to a search and rescue net basket structure. Background Art

[0002] A search and rescue basket is a tool used for emergency rescue, especially in dangerous environments such as mines and construction sites. Its main function is to help rescuers quickly and safely transport the injured or trapped from dangerous areas to a safe place.

[0003] The search and rescue basket in the prior art needs to be used in conjunction with a lifting device, which controls the lifting of the search and rescue basket. In actual use, if the water flow is turbulent and the search and rescue environment is complex, the search and rescue basket is likely to fall off the lifting rope. Without the tension of the lifting rope, the search and rescue basket will directly sink into the water. If the search and rescue basket falls off and sinks into the water, the search and rescue object may be in greater danger due to the inability to be rescued in time. The falling of the search and rescue basket means the loss of a key rescue tool, which may make the search and rescue work more difficult and dangerous.

[0004] Therefore, it is necessary to design a search and rescue basket structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a search and rescue net basket structure.

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

[0007] A search and rescue basket structure, comprising a search and rescue basket, and further comprising:

[0008] The inner rib ring is annular in structure and is fixed at the top position inside the search and rescue net basket;

[0009] An annular float bag is fixedly mounted on the top of the outer surface of the search and rescue net basket;

[0010] Two cylinders, both arranged on the inner rib ring;

[0011] Four connecting rods, the cylinder is fixed to the inner rib ring through two connecting rods;

[0012] Two driving structures are respectively arranged inside the two cylinders;

[0013] The two inflatable structures are respectively arranged inside the two cylinders.

[0014] As a preferred technical solution of the present invention, the driving structure includes:

[0015] a rotating block, rotatably arranged inside the cylinder;

[0016] A moving block is slidably arranged inside the cylinder;

[0017] A limiting groove is provided on the inner surface of the cylinder;

[0018] A limiting block is fixed on the moving block and is slidably arranged in the limiting groove;

[0020] As a preferred technical solution of the present utility model, the inflatable structure includes:

[0021] an air bag, one end of which is connected to the inner surface of the cylinder and the other end of which is connected to the moving block;

[0022] a spring, disposed inside the airbag;

[0023] Two trachea, one end of each of which is connected to the airbag, and the other end of one of the trachea is connected to the annular floating bag;

[0024] Two one-way valves are respectively installed on the two air pipes.

[0025] As a preferred technical solution of the present invention, a handle is installed on one end of the rotating shaft located outside the cylinder.

[0028] The utility model has the following beneficial effects:

[0029] As the airbag continues to inflate and expand the annular buoy, it floats on the water's surface. This prevents the device from sinking if the sling becomes detached, thereby improving the safety and success rate of search and rescue operations. Operators simply turn the handle to drive the shaft, which in turn inflates the airbag. This simple operation reduces complexity and makes it easier for operators to operate in high-pressure environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 2 Schematic diagram of the driving structure and the inflation structure.

[0032] In the figure: 1 search and rescue net basket, 2 inner rib ring, 3 annular float bag, 4 cylinder, 5 connecting rod, 61 rotating block, 62 moving block, 63 limiting groove, 64 limiting block, 65 rotating shaft, 71 air bag, 72 spring, 73 air pipe, 74 one-way valve. DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-2 A search and rescue basket structure includes a search and rescue basket 1, and further includes: an inner rib ring 2, which is annular and fixed to the top position inside the search and rescue basket; an annular float 3, which is fixedly sleeved on the top position of the outer surface of the search and rescue basket 1; two cylinders 4, both arranged on the inner rib ring 2; and four connecting rods 5, wherein the cylinders 4 are fixed to the inner rib ring 2 through two connecting rods 5;

[0035] The search and rescue net basket 1 also includes two driving structures, which are respectively arranged inside the two cylinders 4. The driving structure includes: a rotating block 61, which is rotatably arranged inside the cylinder 4; a moving block 62, which is slidably arranged inside the cylinder 4. The rotating block 61 and the moving block 62 together form a cylindrical structure. The rotating block 61 and the moving block 62 are the same size. The opposite ends of the rotating block 61 and the moving block 62 are provided with inclined surfaces, and the outer edges of the rotating block 61 and the moving block 62 are in contact with the inner surface of the cylinder 4; a limiting groove 63 is opened on the inner surface of the cylinder 4; a limiting block 64 is fixed on the moving block 62 and is slidably arranged in the limiting groove 63; a rotating shaft 65, one end of which is fixedly connected to the rotating block 61 and the other end extends to the outside of the cylinder 4. A handle is installed at one end of the rotating shaft 65 located outside the cylinder 4. The axis is set. When the search and rescue net basket 1 proposed by the utility model is in use, after the search and rescue net basket 1 completes the rescue of the rescuer, the staff rotates the handle on the rotating shaft 65 to rotate the rotating shaft 65. When the rotating shaft 65 rotates, it can drive the rotating block 61 to rotate. Since the rotating block 61 and the moving block 62 together form a cylindrical structure, the rotating block 61 and the moving block 62 are the same size. The opposite ends of the rotating block 61 and the moving block 62 are both provided with inclined surfaces. The outer edges of the rotating block 61 and the moving block 62 are both in contact with the inner surface of the cylinder 4. Therefore, during the rotation of the rotating block 61, the inclined surface part of the rotating block 61 can squeeze the inclined surface part of the moving block 62. Under the limiting action of the limiting groove 63 and the limiting block 64, the moving block 62 cannot rotate with the rotating block 61, so the moving block 62 will move under the squeezing action of the rotating block 61.

[0036] The search and rescue net basket 1 also includes two inflatable structures, which are respectively arranged inside the two cylinders 4. The inflatable structures include: an air bag 71, one end of which is connected to the inner surface of the cylinder 4 and the other end is connected to the moving block 62; a spring 72, which is arranged inside the air bag 71; two air pipes 73, one end of which is connected to the air bag 71, and the other end of one of the air pipes 73 is connected to the annular float 3; two one-way valves 74 are respectively installed on the two air pipes 73. During the rotation of the rotating block 61, the moving block 62 can periodically squeeze the air bag 71, and cooperate with the spring 72 inside the air bag 71 to press the air bag 71. 2, the elastic force of the airbag 71 is continuously compressed and restored. Since the flow limiting directions of the two one-way valves 74 are opposite, specifically, one of the one-way valves 74 limits the gas to only enter the interior of the airbag 71 from the external environment, and the other one-way valve 74 limits the airflow to only enter the interior of the annular float 3 from the interior of the airbag 71. In summary, when the staff turns the handle, the airbag 71 can continuously inflate the annular float 3, causing the annular float 3 to inflate. The inflated annular float 3 can float on the water surface, preventing the search and rescue net basket 1 from sinking into the water after falling off the lifting rope.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
