Description

Technical Field

[0001] This utility model relates to the field of underwater salvage operation technology, specifically to an underwater search and rescue device. Background Technology

[0002] Underwater search and rescue is a complex and dangerous task that requires rescuers to possess professional skills and excellent psychological qualities. Furthermore, the use of search and rescue equipment and the formulation of search and rescue strategies are also key factors in ensuring the success of the rescue operation.

[0003] Chinese Patent No. CN215436859U discloses an underwater search and rescue system, belonging to the field of salvage operation technology. The system aims to provide a convenient and safe underwater search and rescue system for locating and locating drowned bodies or persons without causing harm. The system includes a search and rescue boat, a placement compartment, a search device, and a salvage device. The search and rescue boat is used for faster salvage or rescue operations. The placement compartment is used to hold and accommodate salvaged objects, and is detachably connected to the search and rescue boat. The search device is used to search for bodies or drowning persons underwater. The salvage device is used to retrieve the found bodies or drowning persons from the bottom of the water.

[0004] The device is designed to use traditional search and rescue boats for search and rescue operations. However, some small lakes and rivers do not have search and rescue boats on standby at all times. Search and rescue boats are too bulky, and it is very costly to mobilize search and rescue boats from outside to carry out rescue operations. In addition, the terrain in small lakes and rivers is complicated (such as narrow rivers), and the large size of search and rescue boats is not conducive to the execution of rescue operations. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides an underwater search and rescue device to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An underwater search and rescue device includes a small unmanned surface vessel (USV). A support frame is mounted on the USV, and an installation body is mounted on the support frame. A baffle is provided on one side of the installation body, and a support cylinder is provided between the installation body and the baffle. A retraction mechanism is provided on the installation body, and the drive unit of the retraction mechanism is linked to the support cylinder. A lifebuoy and a hose are wound around the support cylinder. An inflation mechanism is mounted on the installation body, with the input end of the hose in fluid communication with the output end of the inflation mechanism, and the output end of the hose in fluid communication with the inside of the lifebuoy.

[0008] Preferably, the shrinkage mechanism includes a cylinder mounted on a mounting body, the mounting body having a clearance groove on the side near the baffle, the free end of the cylinder being inserted into the clearance groove, and one end of the support cylinder being inserted into the clearance groove and fixedly connected to the free end of the cylinder.

[0009] Preferably, the inflation mechanism includes an installation cylinder fixed on the mounting body, the output end of the installation cylinder being in fluid communication with the input end of the hose, and a high-pressure gas storage tank being detachably connected inside the installation cylinder.

[0010] Preferably, the life ring is equipped with a solenoid valve, and the output end of the hose is in fluid communication with the input end of the solenoid valve.

[0011] Preferably, the other end of the life ring is provided with a first hook, and the life ring is provided with a plurality of second hooks.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Compared with traditional search and rescue boats, this device is less expensive and smaller in size, making it easier to transport and more suitable for search, rescue, and salvage operations in complex terrain such as small lakes and rivers, making it highly practical.

[0014] 2. When performing salvage operations, this device only requires placing the lifebuoy around the person or object that has fallen into the water, and then hooking the first hook onto the shackle. When the lifebuoy inflates, it automatically locks the person or object in the water, and at the same time, the lifebuoy carries the object to the surface. Compared with the traditional method of using ropes to lock the person or object in the water, its locking operation is simpler and faster. Attached Figure Description

[0020] The following will be for reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0021] An underwater search and rescue device, such as Figure 1 and Figure 2 As shown, the device includes a small unmanned surface vessel (USV) 1, a support frame 2 mounted on the USV 1, a mounting body 3 mounted on the support frame 2, a baffle 4 on one side of the mounting body 3, a support cylinder 5 between the mounting body 3 and the baffle 4, and a retraction mechanism on the mounting body 3. The drive unit of the retraction mechanism is linked to the support cylinder 5. The retraction mechanism includes a cylinder 8 mounted on the mounting body 3, a control system mounted on the cylinder 8, and the control system is connected to an external remote control device. The external remote control device can control the retraction of the cylinder 8. A clearance groove 9 is provided on the side of the mounting body 3 near the baffle 4. The free end of the cylinder 8 is inserted into the clearance groove 9, and one end of the support cylinder 5 is inserted into the clearance groove 9 and fixedly connected to the free end of the cylinder 8. A lifebuoy 6 and a hose 7 are wound around the support cylinder 5. The hose 7 is a flexible tube with a mesh sleeve on the surface and has high tensile strength.

[0022] When the free end of the cylinder 8 retracts, the support cylinder 5 is retracted into the relief groove 9, and at the same time, the lifebuoy 6 and hose 7 are no longer covered by the support cylinder 5. The lifebuoy 6 and hose 7 fall into the water, thereby realizing the deployment of the lifebuoy 6 and hose 7.

[0023] like Figure 1 and Figure 2 As shown, an inflation mechanism is installed on the mounting body 3. The input end of the hose 7 is in fluid communication with the output end of the inflation mechanism, and the output end of the hose 7 is in fluid communication with the inside of the life ring 6. The inflation mechanism includes a mounting cylinder 10 fixed on the mounting body 3. The output end of the mounting cylinder 10 is in fluid communication with the input end of the hose 7. A high-pressure air tank 11 is detachably connected inside the mounting cylinder 10. The outer surface of the high-pressure air tank 11 is threadedly connected to the inner wall of the mounting cylinder 10. The output end of the high-pressure air tank 11 is located inside the mounting cylinder 10. After the high-pressure air tank 11 is installed inside the mounting cylinder 10, the output end of the high-pressure air tank 11 is opened.

[0024] like Figure 3 As shown, a solenoid valve 12 is installed on the lifebuoy 6. The output end of the hose 7 is in fluid communication with the input end of the solenoid valve 12. The solenoid valve 12 has two opening methods: a start button on the solenoid valve 12, which allows manual opening of the solenoid valve 12; and a control system on the solenoid valve 12, which is also connected to an external remote control device. The solenoid valve 12 can be opened by the external remote control device. Opening the solenoid valve 12 by the remote control device is existing technology and will not be described in detail here.

[0025] like Figure 3 and Figure 4 As shown, one end of the life ring 6 is provided with a retaining ring 13, the other end of the life ring 6 is provided with a first hook 14, and the life ring 6 is provided with several second hooks 15.

[0026] When the device is in use, if a person falls into the water, the small unmanned boat 1 is remotely driven to reach the vicinity of the person. Then, the cylinder 8 is activated by the external remote control device. The free end of the cylinder 8 retracts, causing the support cylinder 5 to retract into the relief groove 9. The lifebuoy 6 and hose 7 are no longer covered by the support cylinder 5, that is, the lifebuoy 6 and hose 7 fall into the water, thereby realizing the deployment of the lifebuoy 6 and hose 7.

[0027] Then, the solenoid valve 12 is opened remotely, and the high-pressure gas in the high-pressure gas tank 11 passes through the mounting cylinder 10, the hose 7 and the solenoid valve 12 in sequence, and finally enters the interior of the lifebuoy 6, causing the lifebuoy 6 to expand rapidly, thereby achieving timely rescue of people who have fallen into the water.

[0028] When conducting search operations, the small unmanned surface vessel 1 is equipped with radar 16 on its bottom. The small unmanned surface vessel 1, together with radar 16, can conduct search operations in small lakes and waterways with complex terrain (such as narrow waterways), making it highly practical.

[0029] When conducting salvage operations, the small unmanned boat 1 reaches the vicinity of the person or object that has fallen into the water. Taking the fallen object as an example, the cylinder 8 is activated by an external remote control device to retract the support cylinder 5 into the clearance groove 9, thereby deploying the lifebuoy 6 and the hose 7. Due to factors such as the weight of the first hook 14 and the second hook 15, the lifebuoy 6 sinks into the water. Then, the salvage personnel place the lifebuoy 6 around the fallen object and hook the first hook 14 onto the retaining ring 13. Then, they manually open the solenoid valve 12 to rapidly inflate the lifebuoy 6. After the lifebuoy 6 inflates, the inner ring of the lifebuoy 6 shrinks and locks the fallen object. At the same time, the lifebuoy 6 floats up and brings the fallen object to the surface, thus completing the salvage operation of the device.

[0030] It should be noted that, depending on the specific circumstances of the object falling into the water, if the object has a support (such as a lug), the second hook 15 can be connected to the support to increase the connection strength between the lifebuoy 6 and the object, reducing the possibility of the lifebuoy 6 detaching from the object when it floats up. It is also worth noting that if the object is small, the retaining ring 13 can be connected to the corresponding second hook 15 to reduce the internal space of the lifebuoy 6, thereby ensuring the locking effect on the object.

[0031] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
