Description

Technical Field

[0001] The present invention relates to the technical field of underwater rescue, and particularly relates to a multifunctional underwater rescue device. Background Art

[0002] An underwater rescue device refers to various equipment or systems specifically designed to perform rescue tasks in an underwater environment. Its core value lies in dealing with emergencies, such as diving accidents and drowning rescue scenarios. However, the underwater rescue scenarios are not limited to the well-known open underwater waters. Some relatively concealed environments, such as wells, also require the use of underwater rescue devices to carry out rescue work. Specifically, when someone accidentally falls into a well, due to the extremely limited space at the wellhead and below it (including the sewer under the well), the movement freedom of the rescue personnel is restricted. When they try to enter or perform rescue actions, their bodies are difficult to stretch, and they cannot fully display their rescue skills. Therefore, an underwater rescue device is needed to rescue the drowning person from the well.

[0003] When the existing underwater rescue devices are in use, most of them fix the drowning person with their clamping parts after the device enters the well and then drag the drowning person out of the well. However, when the clamping part in the traditional underwater rescue device clamps the drowning person, the clamping opening thereof usually needs to be further enlarged to complete the clamping action. This means that during the clamping process, the maximum length of the overall device will increase. In the narrow space under the well, the device with the increased maximum length is extremely likely to collide with the surrounding environment or even get stuck, greatly increasing the rescue difficulty and risk. Moreover, during the process of rescuing the drowning person, in order to prevent the drowning person from slipping due to struggling or to avoid secondary injuries to the drowning person, the rescue personnel usually use a rescue net to wrap the drowning person. However, due to the usually narrow space at the wellhead and under the well, it is difficult for the rescue personnel to quickly and effectively complete the wrapping operation on the drowning person, thus reducing the overall rescue quality and rescue efficiency, and the practicality is not good.

[0015] Compared with the existing technology, the advantages of the present invention are as follows: 1. Through the mutual cooperation of the first propeller, the clamping and fixing mechanism and the wrapping mechanism, the present invention can not only keep the maximum diameter of the overall structure formed by the combination of the arc-shaped gear ring and the arc-shaped shell unchanged when clamping and fixing a drowning person who has fallen into the well, thus effectively avoiding the problems of collision and jamming with the surrounding environment, and further effectively ensuring the rescue quality and rescue efficiency of the entire device. It can also use the extension of the arc-shaped gear ring, the activation of the electromagnet, the rotation of the rotating plate, and the winding of the first towing rope and the second towing rope to realize the tight wrapping of the front and back sides of the drowning person without manual operation, thus effectively avoiding the drowning person from slipping or being secondarily injured due to struggling. And compared with the traditional method, it simplifies the operation process, and further effectively improves the overall rescue quality and rescue efficiency.

[0016] 2. Through the mutual cooperation of the detection device, the first propeller, the second propeller, and the clamping and fixing mechanism, the present invention can flexibly adjust the posture and perform the clamping and fixing operation according to the posture of the drowning person falling into the well. Thus, when clamping and fixing the drowning person, the body of the drowning person can always be adjusted to the supine state, and under the action of the inflated first airbag and second airbag, it is ensured that the head of the drowning person quickly and stably emerges from the water surface. At the same time, it is ensured that the drowning person always maintains the supine state during the movement of the device, reducing the staying time of the drowning person underwater and winning precious time for subsequent further rescue, thereby effectively improving the rescue efficiency. In addition, through the setting of the inflated third airbag, the buoyancy of the lower body of the drowning person can be enhanced, enabling the whole body to remain stable in the water and effectively preventing the drowning person from tilting and sinking, thus effectively improving the rescue quality.

[0017] 3. Through the setting of the wrapping mechanism, while achieving the tight wrapping of the front and back sides of the drowning person, the sequential wrapping of the back side of the drowning person by the first rescue net and the second rescue net can effectively avoid the dislocation or gap problems that may occur during the synchronous pulling of the double nets, thus effectively ensuring the tightness of the wrapping. Moreover, the double-layer wrapping of the back side of the drowning person by the first rescue net and the second rescue net can increase the difficulty for the drowning person to break free. Even if the drowning person tries to break free in a panic, the double-layer wrapping can make it difficult for the drowning person to easily break away from the restraint, thereby further improving the rescue quality.

[0018] 4. Through the setting of the cutting mechanism, before adjusting the posture and performing the clamping and fixing operation on the drowning person, the cutting blade can cut the waterweeds that may be entangled on the body of the drowning person at the bottom of the water (if the drowning person at the bottom of the water is not entangled with waterweeds, the above cutting operation is not required). Thus, the interference of waterweeds on the subsequent rescue operation can be effectively eliminated, ensuring that the entire device can smoothly contact and act on the body of the drowning person, effectively guaranteeing the rescue quality and rescue efficiency.

[0030] The overall volume of the device in the present invention is small and can enter the sewer through the narrow space of the wellhead without complex equipment installation or space adjustment, thus greatly shortening the rescue preparation time. By adjusting the rotation speed and direction of the four first propellers 2 on the installation housing 1, the entire device can achieve flexible movement in three-dimensional space to adapt to complex water flow and terrain conditions. And in some narrow gaps where some machines cannot enter, the first electric telescopic rod 9 can be used to extend the first propeller 2 and probe it into the gap, and use the water flow power generated when the first propeller 2 rotates to safely push the drowning person out of the gap, increasing the possibility of rescue operations.

[0031] When the underwater rescue device is put into the well, if the drowning person in the well is in a coma, the detection device 4 is used to observe the posture of the drowning person. If the drowning person is detected to be floating in the water, the first propeller 2 is started, and the angle of the first propeller 2 is adjusted by controlling the spherical adjustment part 12, so that the whole device moves to the back of the drowning person, and at the same time, the arc-shaped shell 8 and the rubber pad 21 on the first arc-shaped fixing block 15 are in contact with the back of the drowning person. Then, the first propeller 2 drives the whole device to move, so that the arc-shaped shell 8 and the first arc-shaped fixing block 15 on the device are in contact with the back of the drowning person. 5 drives the body of the drowning person to move until the drowning person is adjusted to a supine position. After the posture adjustment is completed, the first propeller 2 is continued to be operated to move the two arc-shaped shells 8 on the device to a position that matches the height of the drowning person's chest. Then, by starting the two second motors 26, the two third gears 25 are rotated, so that the two arc-shaped gear rings 13 are respectively rotated out of the two arc-shaped shells 8 (at this time, the two arc-shaped gear rings 13 rotate in opposite directions). In this process, the two arc-shaped gear rings 13 can cooperate with the two arc-shaped shells 8 to directly clamp and fix the drowning person's chest.

[0032] If the drowning person sinks to the bottom of the water and is entangled with water plants, the cutting blade 38 in the sleeve 10 is first extended by controlling the second electric telescopic rod 37, and the cutting blade 38 is rotated by starting the second rotating part, thereby cutting the water plants entangled with the drowning person (if the drowning person sinks to the bottom of the water is not entangled with water plants, the above-mentioned cutting operation is not necessary). If the drowning person is lying on the bottom of the water at this time, the first propeller 2 driving device is first used to move so that the arc-shaped housing 8 and the rubber pad 21 on the first arc-shaped fixing block 15 contact the back of the drowning person, and then the angle of the second propeller 3 is adjusted by controlling the first rotating part. The angle of the device is adjusted to make it slightly tilted, and then the second propeller 3 is turned on to disturb the water flow near the drowning person, so that the body of the drowning person is slightly floated a certain distance by the force of the water flow. At this time, the second motor 26 is controlled to make the arc-shaped gear ring 13 slightly extend from the arc-shaped shell 8, so as to preliminarily clamp the chest of the drowning person, and then the position and posture of the entire device are adjusted by controlling the first propeller 2 until the body of the drowning person is synchronously adjusted to the supine state, and finally the second motor 26 is controlled to make the arc-shaped gear ring 13 cooperate with the arc-shaped shell 8 to clamp and fix the chest of the drowning person.

[0033] If the drowning person lies at the bottom of the water, only the first propeller 2 is used to make the rubber pads 21 on the arc-shaped housing 8 and the first arc-shaped fixing block 15 contact the front chest of the drowning person. After repeating the above operation of using the second propeller 3 to slightly lift the body of the drowning person by a certain distance, the first propeller 2 is used to make the arc-shaped housing 8 and the first arc-shaped fixing block 15 rotate along the body of the drowning person. During this process, the first propeller 2 is controlled to make the arc-shaped housing 8 and the first arc-shaped fixing block 15 drive the drowning person to move upward until the rubber pads 21 on the arc-shaped housing 8 and the first arc-shaped fixing block 15 contact the back of the drowning person. At this time, the second motor 26 is controlled to make the arc-shaped gear ring 13 slightly extend from the arc-shaped housing 8, and then the body of the drowning person is adjusted to the supine state by controlling the first propeller 2. Finally, the above-mentioned clamping and fixing operation of the arc-shaped gear ring 13 on the chest of the drowning person is repeated.

[0034] There are obvious design limitations in the clamping part of traditional underwater rescue devices. The size of the clamping opening on it is fixed. When facing complex scenarios such as underground rescue, once the size of the wellhead is smaller than the size of the clamping opening on it, it cannot enter at all, greatly limiting the working range of the underwater rescue device. In the initial state (i.e., when not extended), the overall volume of the arc-shaped gear ring 13 and the arc-shaped housing 8 is only half of that when clamping. This enables it to easily enter narrower spaces in the initial state, effectively ensuring the wide applicability of the entire device. When clamping a drowning person through the clamping part, the clamping opening on it usually needs to be further enlarged to complete the clamping action. This means that during the clamping process, the maximum length of the space occupied by the entire device will increase. In a narrow underground space, the device with an increased length is extremely likely to collide with the surrounding environment or even get stuck. When using the arc-shaped gear ring 13 and the arc-shaped housing 8 for clamping and fixing operations, the maximum diameter of the overall structure formed by their combination always remains unchanged. In a narrow space, it can complete the clamping action while maintaining a stable size, effectively avoiding collisions and jamming problems with the surrounding environment, thus effectively ensuring the rescue quality and rescue efficiency of the entire device.

[0035] As the arc-shaped gear ring 13 extends from the arc-shaped housing 8, the first airbag 34 and the second airbag 35 inside the arc-shaped gear ring 13 will be exposed. At the same time, the first inflation device 36 is used to inflate the first airbag 34 and the second airbag 35, so that the first airbag 34 and the second airbag 35 have completed the inflation operation when the arc-shaped gear ring 13 completes the clamping and fixing operation, effectively saving the waiting time generated by the step-by-step operation of fixing first and then inflating in the traditional method. The inflated first airbag 34 and second airbag 35 can make the chest of the drowning person float upward, so that the head can emerge from the water surface and the drowning person can always maintain a supine state during the process of being moved by the device.

[0036] Since the first mounting groove and the second mounting groove are arranged to penetrate the side close to the second airbag 35, when the arc-shaped toothed ring 13 completes the clamping, the part that is in direct contact with the body of the drowning person is the second airbag 35 with a relatively small volume. This design enables the second airbag 35 to well fill the gap between the body of the drowning person and the arc-shaped toothed ring 13, and the second airbag 35 can automatically adjust according to the curve and posture of the drowning person's body, so that the entire device fits tightly to the body of the drowning person. At the same time, when the drowning person maintains an upward posture, force can be applied more accurately to ensure that the drowning person's head is stably above the water surface, thereby improving the success rate of rescue. In addition, the second airbag 35 also has a cushioning effect. During the rescue operation of this device, it can effectively reduce the impact and squeezing on the body of the drowning person, and avoid secondary damage to the drowning person due to the rigid contact of the underwater rescue device. The relatively large first airbag 34 can provide a large and stable buoyancy. When it is necessary to rescue the drowning person, the quickly inflated large airbag can quickly generate sufficient buoyancy to lift the drowning person from the water and get his head out of the water as soon as possible, reducing the drowning person's stay time underwater, and gaining precious time for subsequent further rescue, thereby effectively improving the rescue efficiency.

[0037] While the arc-shaped toothed ring 13 cooperates with the arc-shaped shell 8 and the second airbag 35 to position and fix the upper body of the drowning person (i.e., while inflating the first airbag 34 and the second airbag 35), the second inflation device 39 located inside the second arc-shaped fixing block 17 is synchronously started and inflates the two third airbags 40 inside the second arc-shaped fixing block 17. The inflated third airbag 40 can fit the waist of the drowning person (when the arc-shaped toothed ring 13 is located on the chest of the drowning person, the second arc-shaped fixing block 17 is also correspondingly located on the waist of the drowning person), thereby cooperating with the arc-shaped toothed ring 13 and the arc-shaped shell 8 to more effectively fix the body of the drowning person, and the presence of the third airbag 40 can enhance the buoyancy of the lower body of the drowning person, so that the whole body can remain stable in the water, effectively preventing the drowning person from tilting and sinking, and further improving the success rate of rescue.

[0038] On two opposite side walls of the U-shaped mounting plate 5, there are a first rescue net 23 and a second rescue net 29 whose upper halves are wound up by a rotating rod. The lower halves of the first rescue net 23 and the second rescue net 29 are placed on the top end of the rotating plate 20. At this time, the first rescue net 23 and the second rescue net 29 are located between the corresponding baffle 6 and the rotating plate 20. The baffle 6 is used to block and protect the first rescue net 23 and the second rescue net 29, so as to prevent the first rescue net 23 and the second rescue net 29 from being scratched or collided by external sundries during daily storage or device movement, ensuring that they can remain intact when needed for use, so as to smoothly carry out rescue work. During the rotation and extension of the arc-shaped gear ring 13, the sliding rod 22 and the fixed rod 30 will drive the first rescue net 23 and the second rescue net 29 to surround the front of the drowning person respectively. When the first rescue net 23 and the second rescue net 29 perform the above-mentioned enclosing action, the electromagnet 24 is activated. Since the electromagnet 24 on the first rescue net 23 and the electromagnet 24 on the second rescue net 29 have opposite magnetic poles, when the first rescue net 23 and the second rescue net 29 complete the enclosing action, the electromagnets 24 on the first rescue net 23 and the second rescue net 29 will contact each other and fit tightly together, thereby firmly connecting the first rescue net 23 and the second rescue net 29 into a whole and wrapping the front of the drowning person.

[0039] During this process, since a sliding groove is jointly opened at the bottom end of the arc-shaped gear ring 13 located above and the bottom end of the first connecting block, and the sliding rod 22 can slide in the sliding groove, and at the same time, the electromagnets 24 on the first rescue net 23 and the second rescue net 29 are in an adsorbed state, therefore, the sliding rod 22 will be pushed by the second rescue net 29 fixed on the arc-shaped housing 8 on the other side. At this time, by controlling the first driving part, the rotating rod connected to the first rescue net 23 is rotated. Under the cooperation of the pulling force of the rotation of the rotating rod and the pushing force of the second rescue net 29, a part of the first rescue net 23 will be gradually wound up (at this time, the area of the first rescue net 23 wrapping the drowning person is smaller than the area of the second rescue net 29 wrapping the drowning person). At the same time, during the enclosing action, the second driving part will be synchronously controlled to rotate the rotating plate 20, so that the top end on which the first rescue net 23 and the second rescue net 29 are placed is put down, and finally the situation shown in Figure 8 is formed.

[0040] Subsequently, the first motor 11 is started, driving the first gear 18 and the fourth gear 33 to rotate through the second gear 19, so as to wind up the second towing rope 28 and the first towing rope 27 through the first rotating rod 31 and the second rotating rod 32. Since the bottom end of the first towing rope 27 is connected to the corner at the bottom end of the first rescue net 23, and the bottom end of the second towing rope 28 is connected to the corner at the bottom end of the second rescue net 29, when the first towing rope 27 and the second towing rope 28 are wound up, the first rescue net 23 and the second rescue net 29 will gradually move from both sides to the rear of the drowning person and tighten, and finally wrap the drowning person from the rear. Through this way of wrapping from the front and rear sides at the same time, the first rescue net 23 and the second rescue net 29 can ensure that the drowning person is completely fixed, thus avoiding the drowning person slipping or suffering secondary injuries due to struggling, and effectively improving the rescue quality.

[0041] And because the diameter of the first gear 18 is smaller than that of the fourth gear 33, the winding speed of the first towing rope 27 is relatively fast. Therefore, when performing the wrapping operation on the rear of the drowning person, the first rescue net 23 with a smaller wrapping area will first approach the drowning person and form a preliminary fixation, and then the second rescue net 29 with a larger wrapping area will cover the outside of the first rescue net 23. This orderly wrapping method can effectively avoid the problems of misalignment or gaps that may occur when the two nets are pulled synchronously, thus effectively ensuring the tightness of the wrapping. In addition, this double-layer wrapping structure increases the difficulty for the drowning person to break free. Even if the drowning person tries to break free in a panic, the double-layer wrapping can also make it difficult for the drowning person to easily break free from the restraint, improving the success rate and reliability of the rescue (that is, further improving the rescue quality).

[0042] Since the arc-shaped gear ring 13 has already determined the position of the drowning person, the first rescue net 23 and the second rescue net 29 can accurately surround the drowning person during the unfolding process. After surrounding to the appropriate position, they will directly wrap the drowning person from both sides and the rear, saving multiple operation steps. Traditional rescue may require approaching the drowning person first and then manually adjusting the rescue equipment for wrapping. This method simplifies the process, thus improving the overall rescue efficiency.

[0043] After moving the drowning person directly below the wellhead, the rescue personnel can untie the first rescue net 23 and the second rescue net 29, and then wind them around both sides of the drowning person's thighs respectively for fixation to restrict the movement of the legs. Then, the rescue rope is buckled on the second support rod 16 on the U-shaped mounting plate 5. Subsequently, through tools such as a pulley block, the drowning person together with this device can be pulled out of the shaft. During this process, the first airbag 34 can also prevent the patient's body from directly colliding with the well wall during the pulling process, thus avoiding secondary injuries to the body.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
