Description

Technical Field

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

[0002] Underwater rescue equipment refers to various types of equipment or systems specially designed to perform rescue missions in underwater environments. Its core value lies in responding to emergencies, such as diving accidents and drowning rescue scenarios. However, underwater rescue scenarios are not limited to the well-known open underwater waters. Some relatively hidden environments, such as wells, also require the use of underwater rescue equipment to carry out rescue work. Specifically, when someone accidentally falls into a well, the space at the wellhead and below it (including the sewer under the well) is extremely limited, which restricts the freedom of movement of the rescuers. When they try to enter or implement rescue actions, it is difficult for them to stretch their bodies and they cannot fully display their rescue skills. Therefore, underwater rescue equipment is needed to rescue the drowning person from the well.

[0003] When using existing underwater rescue devices, most of them are to use the upper clamping part to fix the drowning person after the device enters the well, and then drag the person out of the well. However, when clamping the drowning person, the upper clamping mouth of the clamping part of the traditional underwater rescue device usually needs to be further enlarged to complete the clamping action, which means that during the clamping process, the maximum length of the space occupied by the entire device will increase. In the narrow underground space, the device with the above-mentioned maximum length increase is very likely to collide with the surrounding environment or even get stuck, which greatly increases the difficulty and risk of rescue. In the process of rescuing the drowning person, in order to prevent the drowning person from slipping due to struggling or to avoid secondary injury, rescuers usually use a rescue net to wrap the drowning person. However, since the wellhead and the underground space are usually narrow, it is difficult for rescuers to complete the wrapping operation on the drowning person quickly and effectively, thereby reducing the overall rescue quality and efficiency, and the practicality is poor.

[0021] Compared with the existing technology, the advantages of the present invention are:

[0022] 1. The present invention cooperates with the first propeller, the clamping and fixing mechanism, and the wrapping mechanism. Not only can the maximum diameter of the overall structure formed by the arc-shaped gear ring and the arc-shaped shell remain unchanged when the arc-shaped gear ring and the arc-shaped shell are used to clamp and fix the drowning person who falls into the well, thereby effectively avoiding collision and jamming with the surrounding environment, thereby effectively ensuring the rescue quality and efficiency of the entire device, but 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 traction rope and the second traction rope to achieve tight wrapping of the front and back sides of the drowning person without manual operation, thereby effectively preventing the drowning person from slipping or suffering secondary injuries due to struggling.

[0023] 2.

In addition, through the provision of the inflated third airbag, the buoyancy of the lower body of the drowning person can be enhanced, so that the whole body can remain stable in the water, effectively preventing the drowning person from tilting and sinking, thereby effectively improving the quality of rescue.

[0024] 3. The present invention, through the setting of the wrapping mechanism, can achieve tight wrapping of the front and back sides of the drowning person, and use the first rescue net and the second rescue net to wrap the back of the drowning person in sequence, which can effectively avoid the misalignment or gap problems that may occur when the two nets are pulled synchronously, thereby effectively ensuring the tightness of the wrapping. The double-layer wrapping of the back 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 free, thereby further improving the quality of rescue.

[0025] 4. Through the setting of the cutting mechanism, the present invention can cut the water plants that may be entangled on the drowning person at the bottom of the water through the cutting blade before adjusting the posture of the drowning person and clamping and fixing the drowning person (if the drowning person at the bottom of the water is not entangled in water plants, there is no need to perform the above-mentioned cutting operation), thereby effectively eliminating the interference of water plants on subsequent rescue operations, ensuring that the entire device can smoothly contact and act on the body of the drowning person, and effectively ensuring the quality and efficiency of rescue.

[0047] The device of the present invention has a small overall volume and can enter the sewer pipe through the narrow space of the wellhead, without the need for complicated equipment installation or space adjustment, thereby greatly shortening the rescue preparation time. By adjusting the rotation speed and direction of the four first propellers 2 on the mounting shell 1, the entire device can be flexibly moved in three-dimensional space to adapt to complex water flow and terrain conditions. In narrow gaps that certain machines cannot enter, the first propeller 2 can be extended and inserted into the gap through the first electric telescopic rod 9. The water flow power generated by the rotation of the first propeller 2 can be used to safely push the drowning person out of the gap, increasing the possibility of rescue operations.

[0048] 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.

[0049] 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.

[0050] If the drowning person is lying on the bottom of the water, it is only necessary to use the first propeller 2 to make the arc-shaped shell 8 and the rubber pad 21 on the first arc-shaped fixing block 15 contact the drowning person's chest. After repeating the above-mentioned operation of using the second propeller 3 to slightly float the drowning person's body for a certain distance, use the first propeller 2 to make the arc-shaped shell 8 and the first arc-shaped fixing block 15 rotate along the drowning person's body. In this process, the arc-shaped shell 8 and the first arc-shaped fixing block 15 are controlled by the first propeller 2 to drive the drowning person to move upward until the arc-shaped shell 8 and the rubber pad 21 on the first arc-shaped fixing block 15 contact the drowning person's back. At this time, the arc-shaped gear ring 13 is slightly extended from the arc-shaped shell 8 by controlling the second motor 26, and then the drowning person's body is adjusted to a supine position by controlling the first propeller 2. Finally, the above-mentioned operation of clamping and fixing the drowning person's chest with the arc-shaped gear ring 13 is repeated.

[0051] The clamping part of the traditional underwater rescue device has obvious design limitations. The size of the clamping opening is fixed. When faced with complex scenarios such as underground rescue, once the wellhead size is smaller than the size of the clamping opening, it cannot enter at all, which greatly limits the operating 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 shell 8 is only half of that in the clamping state, which makes it easy to enter a narrower space in the initial state, thereby effectively ensuring the wide applicability of the entire device. In addition, when the clamping part is used to clamp a drowning person, the clamping opening is The arc-shaped gear ring 13 and the arc-shaped shell 8 are usually required to perform the clamping operation, which means that during the clamping process, the maximum length of the space occupied by the device as a whole will increase. In the narrow underground space, the device with increased length is very likely to collide with the surrounding environment or even get stuck. When the arc-shaped gear ring 13 and the arc-shaped shell 8 are clamped and fixed, the maximum diameter of the overall structure formed by the combination of the two remains unchanged. In a narrow space, it can complete the clamping action while maintaining a stable size, effectively avoiding collision and jamming with the surrounding environment, thereby effectively ensuring the rescue quality and efficiency of the entire device.

[0052] As the arc-shaped gear ring 13 extends from the arc-shaped shell 8, the first airbag 34 and the second airbag 35 in the arc-shaped gear ring 13 will be exposed. At the same time, the first airbag 34 and the second airbag 35 are inflated through the first inflation device 36, 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, thereby effectively eliminating the waiting time caused by the traditional step-by-step operation of first fixing and then inflating. The inflated first airbag 34 and the second airbag 35 can make the chest of the drowning person float up, so that the head can float above the water and the drowning person can always keep his head up while being moved by the device.

[0053] 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.

[0054] 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.

[0055] On the two opposite side walls of the U-shaped mounting plate 5, there are a first rescue net 23 and a second rescue net 29 with the upper half of which is rolled up by the rotating rod, and the lower half of the first rescue net 23 and the second rescue net 29 is placed on the top of the rotating plate 20. At this time, the first rescue net 23 and the second rescue net 29 are between the corresponding baffle 6 and the rotating plate 20. The baffle 6 is used to shield and protect the first rescue net 23 and the second rescue net 29, thereby preventing the first rescue net 23 and the second rescue net 29 from being scratched or collided with external debris during daily storage or movement of the device, ensuring that the two can remain intact when they need to be put into use, so as to smoothly carry out rescue work. During the rotation and extension process, the sliding rod 22 and the fixed rod 30 will respectively drive the first rescue net 23 and the second rescue net 29 to surround the drowning person. When the first rescue net 23 and the second rescue net 29 perform the above-mentioned enclosing action, the electromagnet 24 is started. Since the magnetic poles of the electromagnet 24 on the first rescue net 23 and the electromagnet 24 on the second rescue net 29 are opposite, 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.

[0056] In this process, since the bottom ends of the upper arc-shaped gear ring 13 and the bottom ends of the first connecting block are both provided with sliding grooves, and the sliding rod 22 can slide in the sliding grooves, and the electromagnets 24 on the first rescue net 23 and the second rescue net 29 are in an adsorption state, the sliding rod 22 will be pushed by the second rescue net 29 fixed on the other side of the arc-shaped shell 8. At this time, the first driving part is controlled to rotate the rotating rod connected to the first rescue net 23. Under the pulling force of the rotating rod rotation and the pushing force of the second rescue net 29, the first rescue net 23 will be gradually reeled in (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, when performing the enclosing action, the second driving part will be synchronously controlled to rotate the rotating plate 20, so that the first rescue net 23 and the second rescue net 29 placed on its top are lowered, and finally a rescue net 23 and a rescue net 29 are formed. Figure 8 The situation shown.

[0057] Then the first motor 11 is started, and the first gear 18 and the fourth gear 33 are driven to rotate through the second gear 19, so that the second traction rope 28 and the first traction rope 27 are reeled in through the first rotating rod 31 and the second rotating rod 32. Since the bottom end of the first traction rope 27 is connected to the bottom corner of the first rescue net 23, and the bottom end of the second traction rope 28 is connected to the bottom corner of the second rescue net 29, when the first traction rope 27 and the second traction rope 28 are reeled in, the first rescue net 23 and the second rescue net 29 will gradually move toward the rear of the drowning person from both sides and tighten, and finally wrap the drowning person from behind. By wrapping the front and back 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, thereby preventing the drowning person from slipping or suffering secondary injuries due to struggling, thereby effectively improving the quality of rescue.

[0058] And because the diameter of the first gear 18 is smaller than the diameter of the fourth gear 33, the first traction rope 27 is reeled in relatively quickly. Therefore, when wrapping 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 misalignment or gap problems that may occur when the two nets are pulled synchronously, thereby 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 make it difficult for the drowning person to easily break free from the restraints, thereby improving the success rate and reliability of the rescue (that is, further improving the quality of the rescue).

[0059] Since the arc-shaped toothed 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 deployment process. After surrounding the appropriate position, the drowning person is directly wrapped from both sides and the rear, eliminating multiple operating steps. Traditional rescue may require approaching the drowning person first, and then manually adjusting the rescue equipment to wrap it. This method simplifies the process, thereby improving the overall rescue efficiency.

[0060] After the drowning person is moved to the bottom of the well, the rescuers can untie the first rescue net 23 and the second rescue net 29, and then wrap them around the two sides of the drowning person's thighs to fix them and restrict the movement of the legs. The rescue rope is then buckled on the second support rod 16 on the U-shaped mounting plate 5. The drowning person and the device can then be pulled out of the well together with tools such as a pulley set. During this process, the first airbag 34 can also prevent the patient's body from directly colliding with the well wall while being pulled up, thereby avoiding secondary damage to the body.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
