[0024] Example 1:

[0025] See attached Figs. 1-2The gantry frame body 1 provided in this embodiment is a detachable mobile gantry frame, specifically including a frame assembly, mainly comprising three main modules: a left support, a gantry beam, and a right support. The connection between the gantry beam and the support is a plug-in structure, using standard parts for locking, and has a height adjustment function. Both the left and right supports are trapezoidal structures, and the gantry beam is vertically positioned between the left and right supports, together forming a stable gantry frame structure. The top of the left and right supports has downward-extending mounting holes, and both ends of the gantry beam have vertically downward-extending adjustment brackets. The adjustment brackets can be inserted into the mounting holes and locked using standard parts. Preferably, multiple sets of through holes are spaced vertically along the left and right supports, and the through holes communicate with the mounting holes. The adjustment brackets also have several sets of threaded holes correspondingly along the vertical direction, with the spacing between them consistent with the spacing between the through holes. By inserting the adjustment bracket of the gantry beam into the mounting hole, adjusting it to a suitable height, aligning the through holes on the support with the threaded holes on the adjustment bracket, and then locking it by inserting the beam fastening bolts, the installation of the gantry frame is completed. Both ends of the left and right supports are equipped with braked casters for easy and flexible movement of the gantry frame. Next to each caster is a leveling foot, with the four leveling feet forming a rectangle. After moving the frame above the designated access hole using the casters, the leveling feet extend, suspending the casters and improving the stability of the gantry frame. The telescopic assembly is preferably an electric lifting hoist 9 for lifting. The electric lifting hoist 9 is servo-controlled and equipped with a cable organizer, which is installed in the middle of the gantry beam via structural components. This ensures even force distribution on both sides of the gantry frame supports, and the cable organizer prevents the wire rope from becoming tangled or knotted during retraction, providing protection. The toxic and hazardous gas detector 6 and the 360° lighting lamp 5, part of the rescue auxiliary components, are mounted on a bracket via a rail-type lifting structure. This rail-type lifting structure includes a channel-shaped rail, vertically fixed to one side of the bracket. A fixing block is located at the bottom of the channel-shaped rail, with a sliding channel running through it. A lifting rod slides along the channel-shaped rail, its bottom engaging with the sliding channel on the fixing block, allowing it to extend and retract within the channel. A movable slider with a set screw is located at the top of the lifting rod. Several threaded holes on the channel-shaped rail mate with the set screw, the number of which is determined by the adjustment position. The lifting rod is locked by tightening the set screw after sliding it to the designated position. Two rail-type lifting structures are provided, parallel to each other on the bracket, with the toxic and hazardous gas detector 6 and the 360° lighting lamp 5 positioned at the lower ends of the lifting rods. By adjusting the lifting rod and the set screw, the toxic and harmful gas detector 6 and the 360° lighting 5 can be extended into the work site; further expanding the application scenarios of the gantry, it also includes a desktop. When the gantry is not used for rescue work, the adjusting frame can retract the gantry beam to the lowest position, and then the desktop can be installed on the gantry beam as a work surface.

[0026] The blower is mounted on the gantry frame body 1 and extends into the emergency oil tank via a telescopic air supply duct. The blower's start and stop are controlled by a controller 7. The telescopic air supply duct is preferably 5 meters long for practicality. The controller 7, also mounted on the gantry frame body 1, includes data acquisition, analysis, and processing functions. The analyzed data is displayed on a monitor, primarily showing: vital signs of personnel in the oil tank, concentration of toxic and harmful gases in the tank, and the coordinates of personnel within the oil tank. The controller 7 also integrates an intercom system, which works in conjunction with the intercom function on the dedicated safety helmet 2.

[0027] A storage cabinet is provided on one side of the gantry frame body 1 to store rescue-related items such as stretchers, positive pressure respirators, special safety helmets 2, vital sign wristbands 3, safety belts 4, and several spare fall arrest rings. Due to the narrow access to the accident oil pool, a fixed single-person operating stretcher is preferred. The safety belts 4 are five-point harnesses. The special safety helmets 2 are equipped with intercom, lighting, and positioning functions. The special safety helmets 2, vital sign wristbands 3, 360° lights 5, and toxic gas detectors 6 are all electrically connected to the controller 7, transmitting data to the controller 7 for analysis and processing, and displaying it on the display screen 8. The controller 7 integrates lighting control buttons for controlling the 360° lights 5.

[0028] Vital signs wristband 3 is worn by people in the pool and wirelessly uploads the wearer's health information to controller 7, including heart rate, HRV, blood oxygen, blood pressure, body temperature, etc.

[0029] Electric lifting hoist 9, with a load capacity of not less than 500kg; single shaft steel rope length of not less than 20 meters; rope laying function required; integrated with gantry frame as a whole; driven by servo motor or frequency converter, AC 220V voltage.

[0030] The toxic and harmful gas detector 6 monitors the content of gases such as chlorine, methane, carbon monoxide, and hydrogen sulfide. The receiver is integrated into the controller 7, and the data information is displayed on the display screen 8 on the controller 7.

[0031] How to use this utility model:

[0032] The first step is to push the main body 1 of the gantry frame to the access port, unfold it, and lock it in place. Maintenance personnel, wearing vital sign wristbands 3 and special safety helmets 2, enter the accident oil pool of the large oil-immersed transformer to carry out maintenance work.

[0033] The second step is for maintenance personnel to turn on the main power supply of the system when entering the pool. Controller 7 will then operate and collect data, including the concentration of toxic and harmful gases in the pool, the health status of the personnel, and their location coordinates. Simultaneously, the 360° lighting 5 will be turned on, and the light will follow the movement of the maintenance personnel.

[0034] Thirdly, if maintenance personnel experience fainting or other issues while working in the pool, controller 7 will detect the personnel's poor health and issue an alarm. If the level of toxic or harmful gases in the pool exceeds the standard, the system will automatically activate the blower to begin powerful ventilation, ensuring the dilution of the toxic or harmful gases in the pool.

[0035] The fourth step is to use controller 7 to determine if people in the pool need to be rescued; ground personnel will then immediately begin the rescue operation.

[0036] The fifth step is to use the electric lifting hoist 9 to lift the rescued person out of the accident oil pool using a five-point safety harness 4 and a fixed single-person operating stretcher, and send them to the hospital for treatment. The electric lifting hoist 9 should not tilt more than 5 degrees during the lifting and lowering process, which can reduce the collision between the person and the manhole during the lifting and lowering process.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
