Description

Technical Field

[0001] The utility model relates to the technical field of emergency rescue inside a main transformer accident oil pool, and more specifically to the technical field of a limited space emergency rescue suit for a main transformer accident oil pool. Background Art

[0002] The main transformer accident oil pool is an underground sealed space. During maintenance, maintenance personnel may inhale toxic and harmful gases and faint, requiring emergency rescue. Due to the complex on-site environment of the main transformer accident oil pool and the fact that it is a closed space, there is a possibility of excessive levels of toxic and harmful gases, such as chlorine, methane, carbon monoxide, and hydrogen sulfide. Maintenance personnel at the bottom may inhale excessive amounts of toxic and harmful gases, which poses a high safety risk and may cause equipment maintenance personnel to faint at the bottom.

[0003] The manhole for the main transformer accident oil pool is small in size, and after the maintenance personnel at the bottom fainted, emergency rescue was limited. The current solution is to use a gantry with an electric hoist. Rescuers wear positive pressure respirators and handheld lighting devices to search and rescue at the bottom of the waste oil pool. The rescued personnel are hoisted out of the waste oil pool by bundling. The gantry is a single rope, and the legs are unstable, which causes shaking during takeoff and landing, causing the rescued personnel to bump into the edge of the hole, etc., making rescue extremely inconvenient.

[0004] The current rescue plan is for rescuers to wear positive pressure respirators and handheld lighting devices to enter the bottom of the oil pool for search and rescue. The rescued persons are fixed with safety belts, and the outsiders rescue the trapped persons by pulling the ropes with the fixed pulleys of the mobile gantry. Due to the complex on-site environment and the small size of the manhole in the main transformer accident oil pool, the rescue time is long and the rescue efficiency is low when the existing rescue plan and equipment are used for rescue. The existing mobile gantry is a pulley single rope lifting rescue. The gantry is easy to tilt during the rescue process and easy to shake during the lifting process. The rescued persons are at risk of secondary injuries from bumps. Utility Model Content

[0005] The purpose of the utility model is to solve the above technical problems and provide a limited space emergency rescue kit for a main transformer accident oil pool.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model provides an emergency rescue suit for a limited space of a main transformer accident oil pool, which includes a foldable gantry, a foldable stretcher, a hanging basket, a searchlight, a toxic and harmful gas detection device, an exhaust and ventilation system, and a fresh air supply system; when the foldable gantry is in use, it is installed at the opening of the ground foundation above the pool, the hanging basket is arranged in the opening of the ground foundation above the pool through a suspension rope, a lifting drive mechanism for driving the hanging basket to lift is arranged at the top of the foldable gantry, a transfer roller assembly for convenient transfer is arranged at the bottom of the foldable stretcher, a fixed point assembly for fixing the foldable stretcher is arranged at the bottom inside the hanging basket, the searchlight is installed on one side wall of the hanging basket, and the toxic and harmful gas detection device is arranged on the foldable stretcher.

[0008] Both the exhaust and ventilation system and the fresh air supply system are portable.

[0009] Specifically, the foldable gantry can be folded and stored. After being unfolded, it can be stably fixed through leveling feet and will not shake or displace under load; the design of this solution is reasonable, the rescue timeliness is high, the suit is light and simple, and it can be quickly unfolded, realizing the rapid dilution of toxic and harmful gases by the portable exhaust and ventilation system and fresh air supply system; the rapid unfolding and stability of the mobile gantry; the stable posture of the rescued person; the rapid detection of toxic and harmful gases and other multi-functional integrations.

[0010] In one embodiment, the foldable gantry includes a portal-shaped main body. Folding arm assemblies that can be received into the corresponding side walls of the portal-shaped main body are arranged at the bottoms of both side walls of the portal-shaped main body through hinge members. Each folding arm assembly includes two folding arms symmetrically hinged at the bottom of the corresponding side wall through a rotating shaft. Moving rollers are arranged at one ends of the two folding arms close to each other, and leveling feet are arranged at one ends of the two folding arms far from each other.

After the support frame rotates, it forms a three-legged support together with the stretcher main body, so that the foldable stretcher can be stably fixed inside the hanging basket.

[0019] The transfer rollers are short-footed wheels, which are convenient for moving at the bottom of the pit. The height can be reduced to complete the rescue work by a single person at the bottom of the pit. The rescued person is fixed to the stretcher, and the angle of the stretcher main body can be changed to realize the small-hole transfer of the rescued person.
