Description

Technical Field

[0001] The present invention relates to the field of firefighting and rescue, and in particular to a deep well rescue device integrating detection and rescue. Background Art

[0002] At present, the deep well rescue process has the following main problems: first, the well mouth is small, the well is narrow, and the working space is limited; second, the vertical distance is long, and there are potential dangers such as hypoxia and toxic gases; third, the vertical shaft is dark and damp, and the lighting is poor; fourth, the well wall is easy to collapse, which is easy to collapse during excavation and rescue. At present, there are mainly the following deep well rescue methods: first, the rescue personnel do not go down the well, but guide the trapped people to wear equipment by themselves before lifting; second, use ropes to go down the well upright or inverted to lift and rescue people; third, use rescue equipment such as rescue lifting devices; fourth, excavation rescue. Different rescue methods can be used for different well-falling conditions and surrounding geological conditions.

[0003] Deep well rescue is a common problem faced by all fire rescue operations. In the face of a well fall accident, the rescue time is very long, and it is easy to endanger the lives of trapped people and rescuers by digging the soil and rocks around the machine well or using an inverted golden hook to go down the well to rescue people. It is particularly important to use rescue hoisting devices for rescue. At present, most deep well rescue hoisting devices have relatively single functions and cannot successfully complete the underground rescue while detecting the well environment; some rescue hoisting devices use manipulators to lift people who fall into the well. Although pressure sensors are set up to ensure the degree of grip, it is still easy to cause secondary injuries to people who have lost their normal behavior during long-distance lifting; most deep well hoisting devices lack voice interaction functions. Adding voice transmission functions to the device can realize two-way communication between people who fall into the well and the well rescue team, which has a significant effect on improving the success rate of deep well rescue; deep wells such as urban sewage wells and abandoned mines are very likely to contain toxic and harmful gases that seriously threaten the lives and health of people who fall into the well. Accurate air supply and oxygen supply for people who fall into the well can ensure the smooth implementation of deep well rescue work. Summary of the invention

[0047] like Figure 8As shown, in specific use, first select the rescue device frame according to the conditions required for deep well rescue on site, build the frame structure of the well support system (1), and fix the frame base on site. After the well support system (1) is built, the outlet end of the wire reel (13) is connected to the inlet end of the computer (22), the lower longitudinal fixed steel beam (18) is fixed to the lower end of the lower track groove (9), and the directional wheel (21) of the lower longitudinal movable steel beam (20) is embedded in the lower track groove (9) to achieve the lateral movement of the lower longitudinal movable steel beam (20). At the same time, check the use effect of the block (15) and the fixing device to ensure that the limit and fixing devices are reliable and effective, and then fix the winch (12), and pass the winch (12) chain around the lower longitudinal movable steel beam (20) and the four fixed pulleys (19) at the bottom of the lower longitudinal fixed steel beam (18). After the four chains pass through the pulleys, they are rigidly connected to the soft dense mesh steel wire mesh (10) through U-shaped bolts.

[0048] An upper longitudinal movable steel beam (8) is arranged above the frame cross beam (17) of the well support system (1). The upper longitudinal movable steel beam (8) can move on the upper track groove (14) through a directional wheel (21). A slide rail (36) is arranged on the lower surface of the upper longitudinal movable steel beam (8). A slider-type threaded sleeve (35) is arranged in the slide rail (36). The slider-type threaded sleeve (35) can be connected to the upper thread of the controllable hydraulic telescopic rod (34) through a threaded hole. The data transmission line of the wire reel (13) passes through the fixed line hole on the side wall of the threaded sleeve. The lower part is connected to the information detection system (4) and the personnel lifting system (2). The information detection system (4) and the personnel lifting system (2) are lifted to the top of the person who fell into the well through the controllable hydraulic telescopic rod (34). The information detection system (4) has functions such as voice interaction, video transmission and environmental parameter monitoring, and can transmit the environment and personnel conditions in the well to the ground.

[0049] Through the monitoring of the information detection system (4), if the person who fell into the well is conscious and can move independently, the rescue personnel on the well can adjust the lateral movement of the lower longitudinal movable steel beam (20) and the winch (12) to achieve the opening and lowering of the soft dense mesh steel wire mesh (10), so that the soft dense mesh steel wire mesh (10) in a contracted state can be lowered to the side of the person who fell into the well. The rescue personnel can use voice guidance through monitoring to help the person who fell into the well climb onto the soft dense mesh steel wire mesh (10), and finally lift the injured person smoothly and safely. Example

[0050] On the basis of the above technical solution, if the person who falls into the well is unconscious or unable to move autonomously, the temporary lifting system (5) can be used to temporarily lift the person. During the temporary lifting, the person on the well adjusts the position of the upper longitudinal movable steel beam (8) and the controllable hydraulic telescopic rod (34) so ​​that the first bionic clamp (23) reaches one shoulder of the person who falls into the well, and then controls the rotation of the steel rail (37) and adjusts the second bionic clamp (24) so ​​that the second bionic clamp (24) reaches the other shoulder. By controlling the first bionic clamp (23) and the second bionic clamp ( 24) The shoulders of the person who has fallen into the well are clamped and passed through the armpits to form a closed lift. The degree of clamping can be transmitted to the ground computer terminal (3) through the pressure sensor (7) to complete the force control. At the same time, the personnel lifting system (2) is controlled to lower the soft dense mesh steel wire mesh (10) from the other side of the well wall where the person who has fallen into the well is leaning against. When the soft dense mesh steel wire mesh (10) is lower than the human body, the longitudinal movable steel beam (20) is controlled to extend the soft dense mesh steel wire mesh (10), and the person who has fallen into the well is placed on the soft dense mesh steel wire mesh (10) and lifted up to complete the rescue and lifting work.

[0051] When the oxygen concentration underground is low or there are toxic and harmful gases, the ventilation and oxygen supply system (6) can be used to supply air and oxygen to the trapped personnel from the surface to the underground. The air supply pipe (25) is integrated into the temporary personnel lifting system (5). When the clamp (24) is lowered to the position of the trapped personnel, accurate air supply can be achieved in the breathing area of ​​the personnel who fell into the well.

[0052] In addition, according to the actual situation at the rescue site, the present invention can also be designed to adjust the length, width and height of the well support system (1) by adding or removing the channel steel of the detachable frame, thereby realizing the construction of rescue platforms for deep wells of different diameters.

[0053] In summary, the present invention combines two rescue methods, namely, a personnel lifting system and a temporary personnel lifting system, to achieve the smooth lifting of people who fall into a well with different injuries; the present invention can achieve communication between the well and the ground through a portable computer monitoring system and an information detection system on the well, thereby scientifically guiding deep well rescue; the ventilation and oxygen supply system of the present invention can achieve precise air and oxygen supply to trapped persons, prolong the survival time of trapped persons in harmful environments, and improve the success rate of deep well rescue.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
