Description

Rescue device for variable-caliber deep motor-pumped well

Technical Field

The invention relates to the technical field of rescue equipment, in particular to an emergency rescue device specially used for people or animals accidentally falling into deep motor-pumped wells with different calibers and narrow spaces.

Background

The motor-pumped well is not only an important source of agricultural irrigation water in rural areas of China, but also an important supplementary water source of daily water for residents in urban and rural areas of China, and plays an important role in agricultural production and resident life. However, because the well mouth is narrow and hidden and is easy to manage, accidents that people or animals accidentally fall into the well often happen to a large number of open motor-pumped wells scattered in the field, and serious harm is brought to the life and property safety of people. Especially, after some motor-pumped wells in rural areas are scrapped, the motor-pumped wells are not backfilled in time, and the well mouths are not provided with any protective measures, so that careless young children accidentally fall into news of the motor-pumped wells occasionally, and even tragedies occur due to unfavorable rescue. The caliber of a motor-pumped well which is common in rural areas is generally between 30 and 50 centimeters, and the well depth is gradually increased from the past twenty-three meters to the present forty-five meters due to the reduction of the underground water level. The motor-pumped well bore is narrow and small, and once an infant accidentally falls into the well and is clamped in a deep motor-pumped well, the rescue degree of difficulty is very high, and the probability of successful rescue is lower.

After a young child accidentally falls into a deep motor-pumped well with different calibers and a narrow space, the general rescue scheme comprises three types: the first rescue scheme is that a rescue rope is put down, people falling into the well tie the rope on the body of the people, and people pull the rope up at the well mouth in a combined manner, but the actual situation is that the caliber of the motor-pumped well is narrow, the falling into the well is often a small-sized and low-age child without self rescue ability, and the safety rope cannot be tied even if no space exists underground; the second scheme is that earthwork beside a motor-pumped well is dug out by large equipment such as an excavator and the like, and the motor-pumped well is penetrated to rescue the falling personnel when the motor-pumped well is dug deeply to the side of the falling personnel, but the scheme needs to excavate massive earthwork with great care, the rescue speed is slow, and in the excavation process, the motor-pumped well can even be permeated with water and collapse or accidentally fall the earthwork to bury the falling personnel, so that secondary damage is caused; the third scheme is that rescue ropes are tied tightly on the rescue personnel with small stature, the head of the rescue personnel is inverted downwards and goes deep into the well to pull up the people falling into the well, but the scheme needs to find out the rescue personnel with small stature and trained professionally on the rescue site, and the underground rescue space is narrow and even is filled with toxic gas, so that the rescue difficulty is very high.

The prior art discloses a small-diameter deep well rescue device with patent application number 2010100324587, and the technical scheme comprises: the fixed pipe and the moving pipe are square pipes, sling fixing rings are arranged on two sides of the upper end of the fixed pipe and are in welded connection with the fixed pipe, a direction adjusting ring is arranged on the farthest end of the upper side of a guard plate opening and closing adjusting pipe and is in welded connection with the fixed pipe, a moving pipe lifting nut is arranged on the upper end portion of the inner portion of the moving pipe and is in connection with a moving pipe screw, the moving pipe lifting nut is in a shape of an inner circle and an outer square, a supporting plate connecting frame is arranged at the lower end of the moving pipe and is in welded connection with the lower end of the moving pipe, a bearing sleeve is located on the upper portion of the fixed pipe and is in connection with a fixed pipe screw bolt, a power connecting hole is formed in the upper end face of a screw rod and is in connection with an output shaft of a moving pipe lifting motor, the supporting plate is in hinge connection with the supporting plate connecting frame at the lower end of the moving pipe through the supporting plate connecting sleeve and a hinge pin shaft, and the guard plate is in hinge connection with guard plate connecting lugs symmetrically arranged on two sides of the upper end of the fixed pipe through an end and a threaded pin shaft. The position of a moving pipe is adjusted by controlling a sling in a direction, when a supporting plate reaches the bottom of a well or is positioned under feet of a person to be rescued, a supporting plate swinging motor is started to enable the supporting plate to slowly rotate from a vertical position to a horizontal position, meanwhile, a rescue device continuously moves downwards and keeps the edge of the supporting plate in contact with the ground all the time until the two feet of the person to be rescued are placed on the supporting plate and rotate to the horizontal position, a protective plate opening and closing motor is started to enable a protective plate to open to a wall of a well lightly pasted with the protective plate, then, the moving pipe lifting motor is started to enable a fixed pipe and the protective plate to slowly move downwards or enable the moving pipe to move upwards until the upper half of the person to be rescued is wrapped, the protective plate opening and closing motor is started to enable the protective plate to enable the rescued person to tightly hold the supporting plate and smoothly reach the feet of the person to be rescued and rotate to the horizontal position to form protection, then, the sling is lifted to enable the rescue device to reach the well mouth, and the fixed pipe and the protective plate can be detached to be used independently under extreme conditions to rescue.

This current scheme adopts singly to decide pipe, single pipe and single tray structure, moves the pipe position through using the long-range adjustment of direction control hoist cable at the well head. In the deep motor-pumped well rescue process of different bores, because the motor-pumped well bore is general comparatively narrow and small, the wall of a well is hugged closely to most health of the personnel of falling into the well, and the major problem of above-mentioned current rescue ware scheme includes: aiming at motor-pumped wells with different calibers, the existing rescue device structure is not provided with a fixing mechanism for effectively supporting the well wall, the motor-pumped well walls with different calibers cannot be stably supported, when a person falling into the well is located at a deep falling position of dozens of meters in the well, the lengths of a sling and a direction control sling are too long, and the rescue person is difficult to remotely and accurately adjust the position of a single-pipe through the long-distance direction control sling at the well mouth, so that the single-pipe can accurately penetrate through a gap between the body of the person falling into the well and the well wall; the cross section of the supporting plate is larger and is in a shovel shape with an irregular front and back shape, particularly, the fixed pipe and the moving pipe are square pipes, and the falling personnel can be easily contorted in a narrow well wall due to the fact that the cross section of the moving pipe has edges and corners and the cross section of the supporting plate is larger and has an irregular shape in the falling rescue process of the rescue device because the fixed pipe and the moving pipe cannot be accurately positioned; in addition, in the falling process of the square moving pipe and the supporting plate, especially when the fixed pipe and the protective plate are independently used for falling rescue, even falling personnel clamped in the semi-air of the well wall can continuously fall to the bottom of the well due to inaccurate positioning, and rescue failure is caused.

The following describes a rescue example of the rescue device for a variable caliber deep motor-pumped well with reference to the accompanying drawings.

As can be clearly seen from fig. 1, 2, 3 and 4, when a person falling into the well and stuck in the middle of the deep motor-pumped well needs to be rescued, the variable-caliber deep motor-pumped well rescue device is firstly in an initial state, that is, the upper supporting mechanism and the lower supporting mechanism are both in a folded state, the moving pipe 5 is upwards contracted in the fixed pipe 1, the supporting plate 12 is in a vertical state, at this time, 4 sling fixing rings 47 of the variable-caliber deep motor-pumped well rescue device cabin 46 are connected with a winch erected at the wellhead of the motor-pumped well through a steel wire rope, under the control of the rescue person, the variable-caliber deep motor-pumped well rescue device in the initial state is slowly put into the motor-pumped well, and simultaneously, an illuminating lamp 50 and a wide-angle camera 52 at the bottom of the device cabin 46 are utilized to observe the relative distance between the variable-caliber deep motor-pumped well rescue device and the person falling slowly, when the variable-caliber deep motor-pumped well rescue device is close to the body of the falling person, the winch at the well mouth stops acting, the equipment cabin 46 of the variable-caliber deep motor-pumped well rescue device is fixed in the vertical direction, at the moment, the rescue worker remotely controls the reducing motor 35 of the upper supporting mechanism to gradually expand the upper supporting mechanism outwards until the rubber rollers 15 of the four upper pipe arms 45 are tightly attached to the well wall of the motor-pumped well, at the moment, the rescue worker at the well mouth carefully observes the attachment condition of the falling personnel and the well wall of the motor-pumped well through the wide-angle camera 52 again, the remote control lower supporting mechanism rotating motor 30 drives the lower supporting mechanism to rotate, and simultaneously controls the reducing motor 28 of the lower supporting mechanism to gradually expand the lower supporting mechanism outwards until the rubber rollers 15 of the four lower pipe arms 14 are tightly attached to the well wall of the motor-pumped well, and one of the four lower pipe arms 14 of the lower supporting mechanism is just aligned to a larger gap between the falling personnel and the well wall of the motor-pumped well from top to bottom, at the moment, the rescue worker remotely controls a moving pipe lifting motor 2 in a fixed pipe 1 fixedly connected with the lower part of the lower pipe arm 14 to start rotating, the moving pipe 5 and a supporting plate 12 are vertically and downwards inserted into a large gap between a well falling worker and the wall of the motor-pumped well, when the supporting plate 12 in a vertical state is lower than the sole of the well falling worker, the moving pipe lifting motor 2 stops acting, the supporting plate motor 6 is started to enable the supporting plate 12 to rotate to a horizontal position from a vertical position, and at the moment, the sole of the well falling worker is already provided with the supporting plate 12 in the horizontal position to serve as a safety for preventing the well falling worker clamped in the deep motor-pumped well half air from continuing falling in the rescue process. A well mouth rescuer continues to control the other three sleeve pipes 5 and the supporting plates 12 to start to extend downwards until the other three sleeve pipes 5 and the supporting plates 12 all penetrate through gaps between the well falling personnel and the motor-pumped well wall, when the three supporting plates 12 are lower than the soles of the well falling personnel, the supporting plate motor 6 is started to enable the three supporting plates 12 to rotate to the horizontal position from the vertical position, at the moment, the four supporting plates 12 in the horizontal position are completely positioned at the soles of the well falling personnel, the well mouth rescuer can start a winch at the well mouth to vertically and slowly pull up the variable-caliber deep motor-pumped well rescuer, and the four supporting plates 12 of the variable-caliber deep motor-pumped well rescuer support the soles of the well falling personnel and finally rescue the well falling personnel out of the well.

Since the unmanned management abandoned motor-pumped well which is easy to drop into the well is generally exposed in the field, the well bottom usually has a thick layer of sludge garbage or weed leaves, when people who have fallen into the well bottom of the deep motor-pumped well need to rescue, and the rescue procedure of people who need to rescue and are stuck in the air in the deep motor-pumped well is slightly different from the rescue procedure of people who have fallen into the well bottom of the deep motor-pumped well, after a well mouth rescue worker has aligned one of four lower tube arms 14 of a lower support mechanism just from top to bottom at a larger gap between the people who drop into the well and the well wall of the motor-pumped well, a tube lifting motor 2 in a fixed tube 1 of the lower tube arm 14 is controlled to rotate, a tube 5 and a pallet 12 are accurately inserted into the larger gap between the people who drop into the well wall of the motor-pumped well and the well from the well wall of the well vertically downward along the well wall until the bottom end of the pallet 12 in a vertical state is inserted into the bottom sludge or the deepest depth of the feet of the people who drop into the well bottom, a pallet motor 6 is started to rotate the pallet 12 from a vertical position to a sludge or a horizontal position, and the lifting motor 2 makes the pallet 5 continue to extend downward, so that the bottom edge of the tube 12 is always contacted with the bottom edge of the deep well, and the horizontal position, and the drop motor is stopped when the drop motor 12 is rotated, and the drop of the horizontal position gradually, and the leaf of the drop of the horizontal position of the tube 12 is stopped. At the moment, the well mouth rescue worker continues to control the other three sleeve pipes 5 and the supporting plates 12 to start to extend downwards, and the actions are repeated until the other three supporting plates 12 also gradually rotate to the horizontal position and are horizontally positioned under the feet of the falling workers. At the moment, a well mouth rescue worker can start a winch at the well mouth to pull up the variable-caliber deep motor-pumped well rescue device, and the four supporting plates 12 of the variable-caliber deep motor-pumped well rescue device support the soles of the falling workers and finally rescue the falling workers out of the well.

In the whole rescue process, the variable-caliber deep motor-pumped well rescue device can convey oxygen to the people falling into the well through the oxygen conveying port 51 at the bottom of the equipment cabin 46 according to needs, the well mouth rescue personnel can talk with the people falling into the well through the voice communicator 49 to know the physical state of the people falling into the well in the rescue process, and if the people falling into the well can provide certain matching according to the command of the rescue personnel, the rescue process is faster and more convenient.
