[0002] The life-saving trawl is a specially designed trawl, which is used in water rescue operations to help search and rescue personnel quickly locate and recover fallen personnel. The design of such trawl usually takes into account ease of use, stability and high efficiency of rescue capability. Traditional life-saving equipment has certain limitations in water rescue, especially in bad weather or at night, when visibility is poor or water conditions are complex, rescue efficiency and success rate are greatly discounted. With the progress of science and technology, there is an increasing demand for efficient and comprehensive life-saving equipment. SUMMARY
[0003] To solve the above technical problems, the utility model provides a life-saving trawl, which can clearly understand the water surface conditions through the detection device and the lamp strip even in complex situations such as night, ensuring the smoothness of the rescue task and the rescue efficiency.
[0004] The utility model adopts the following technical scheme to realize: a life-saving trawl, including upper pull rope, lower pull rope, be equipped with the fiber net that is composed of fiber belt to insert between the upper pull rope and the lower pull rope, be equipped with the lamp strip on the upper pull rope, be equipped with the mounting plate and the float plate in the upper pull rope middle part, be equipped with the telescopic rope reel on the mounting plate, the telescopic rope reel inside is equipped with the fixed block that is located the center position in the telescopic rope reel, install and encircle the clockwork spring on the fixed block, the telescopic rope that connects clockwork spring, the telescopic rope reel still is equipped with the take-up channel that corresponds to in, the lower pull rope is evenly distributed with the movable buckle, install detachable lead block on the movable buckle, the float plate upper side is equipped with the searchlight ring, be equipped with the detection device on the float plate upper end, the float plate is equipped with the battery that is electrically connected with the detection device, the searchlight ring.
[0005] According to the above technical solution, the upper and lower pull ropes and the fiber net form a basic trawl net structure. An outline light strip is installed on the upper pull rope to facilitate observation of the trawl net's depth. An installation plate and a float are installed in the middle of the pull rope. To ensure the float's function and prevent it from interfering with the trawl net, a telescopic rope reel is installed on the installation plate. The telescopic rope reel contains a telescopic rope connected to the float, ensuring the float remains afloat as the trawl net sinks. The float is equipped with a detection device and a searchlight ring for real-time surface monitoring and illumination. A light strip is connected to the front end of the pull rope, allowing it to move with the rope. In low-light conditions, such as nighttime water rescues, the light strip illuminates the area around the trawl net, facilitating rescuers' observation of its location and surroundings, thus improving rescue accuracy. The upper and lower parts of the entire trawl net structure work together to achieve the rescue function. The searchlight ring and detection device ensure real-time monitoring of the water surface dynamics during use.
[0006] Furthermore, in order to continuously power the light strip, the telescopic rope reel is also equipped with a sealed light strip battery that is electrically connected to the light strip.
[0007] Furthermore, the mounting plate is also provided with a positioning rope ring; the telescopic rope is coiled along the rope winding channel, one end of the telescopic rope is connected to the spring, and the other end extends out of the winding coil. The winding coil and the telescopic rope coil are each provided with corresponding rope outlets. The telescopic rope extends to the outside through the rope outlet and passes through the positioning rope ring to connect with the floating plate.
[0008] According to the above technical solution, in order to enable the floating roof to adjust itself according to the trawl depth, a spring is used to apply a recovery force to the telescopic rope. When the trawl sinks, the buoyancy of the floating roof is greater than the resistance of the spring, and the telescopic rope will continue to extend. When the trawl is lifted, the force exerted by the trawl will offset the buoyancy, at which point the spring will return to its original state and pull the telescopic rope back.
[0009] Furthermore, to facilitate dragging the net, one end of the connecting block is fixedly connected to the upper pull rope, and the other end is equipped with a locking slot. Rescuers can directly connect and use a rope with a locking slot. The upper pull rope has connecting blocks at both ends, and the connecting blocks are fixedly connected to the upper pull rope by screws. The connecting blocks are also equipped with locking slots.
[0010] Furthermore, in order to limit the length of the retractable rope, a stop ball is provided on the retractable rope outside the corresponding rope outlet when the rope is retracted.
[0011] Furthermore, to improve the stability of the mounting plate, the lower part of the mounting plate is fixed to the fiber mesh.
[0012] The beneficial effects of this utility model are as follows: A rescue trawl net, through the combination of two sturdy upper and lower ropes and a fiber net, forms a complete trawl net structure. The upper rope allows rescuers to easily control the trawl net from a distance. In rescue scenarios, such as sea rescue or lake rescue, rescuers can use the ropes to tow the trawl net to the target area, improving the accuracy and operability of the rescue. Lead weights are installed on the lower rope; the weight of the lead weights allows the net to sink to a certain depth in the water, which helps to form an effective capture or interception area in the water, which is very important for rescuing drowning victims or retrieving items. The design of the trawl net takes into account effective distribution and ease of operation in the water; the net portion can sink to a certain depth in the water. The increased depth expands the search and rescue range, especially in waters with large waves, enabling more effective interception and capture of people who have fallen into the water or other floating objects. The light strips provide illumination at night or in low visibility conditions, increasing the search and rescue capabilities of the trawl net. A floating platform equipped with a detector and searchlight ring is installed on the trawl net, allowing for clear understanding of the water surface conditions even during nighttime salvage operations, ensuring the smooth and efficient conduct of the rescue mission. The floating platform is connected to the trawl net via a telescopic rope. When the trawl net sinks in the water, the floating platform floats on the surface. The trawl net has a telescopic rope reel containing a spring, and the telescopic rope is connected to the spring, which enables the automatic retraction of the telescopic rope.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0019] In the description of this utility model, it should be noted that, 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 based on the specific circumstances.
[0020] The following description, with reference to the accompanying drawings, further illustrates a life-saving trawl net according to this utility model:
[0021] like Figures 1-4 The rescue trawl net shown includes an upper pull rope 1 and a lower pull rope 2. A fiber net composed of interlaced fiber strips 3 is provided between the upper pull rope 1 and the lower pull rope 2. A light strip 4 is provided on the upper pull rope 1. An installation plate 5 and a float 6 are provided in the middle of the upper pull rope 1. The lower part of the installation plate 5 is fixed to the fiber net, and the upper part is connected to the upper pull rope. In order to reduce water resistance, the installation plate is provided with water passage holes (not shown). A telescopic rope reel 7 is provided on the installation plate 5. A rope winding reel 8 is provided inside the telescopic rope reel 7. The rope winding reel 8 includes a fixing block 81 located at the center of the rope winding reel 8, a spring 82 surrounding and installed on the fixing block 81, and a connecting spring 82. The telescopic rope 83 and the telescopic rope reel 7 are equipped with a completely sealed LED strip battery 41 that is electrically connected to the LED strip 4. The pull rope is fixedly connected to the LED strip, which is equipped with multiple well-sealed LED bulbs. The LED strip is electrically connected to the LED strip battery through a waterproof wire. The LED strip can play a role in illumination during rescue operations and display the outline of the trawl net in deep water. In low-light environments, such as at night or in areas with insufficient underwater light, the LED strip can provide light to facilitate the search for rescued objects or to determine the location of the trawl net. The LED strip is electrically connected to the battery through a wire, and the LED strip battery 41 provides power to the LED strip. As long as the LED strip battery 41 has power, the LED strip can emit light normally.
[0022] In this embodiment, the rope reel 8 is also provided with a rope winding channel 84 corresponding to the telescopic rope 83. The rope winding channel can prevent the rope from getting tangled during the winding process, ensuring smooth winding. The telescopic rope reel 7 plays the role of automatically storing and releasing the telescopic rope. In different rescue scenarios, such as when the trawl net needs to adapt to different water surface heights or changes in the distance between the rescued object and the trawl net, the telescopic rope reel 7 can automatically release or retract the telescopic rope as needed. When the buoyancy of the float is greater than the resistance of the spring, the telescopic rope will be pulled out. The pull-down rope 2 has movable buckles 21 evenly distributed on it. The movable buckles 21 are equipped with detachable lead blocks 22. The lead blocks quickly sink the bottom into the water, and the trawl net is pulled down under the action of gravity, ensuring that the trawl net has a certain vertical depth distribution in the water. At the same time, it can form a resistance to the buoyancy of the float, which can further realize the automatic pulling out of the telescopic rope.
[0023] A positioning rope ring 51 is also provided on the mounting plate 5. The telescopic rope 83 is coiled along the rope winding channel 84. One end of the telescopic rope 83 is connected to the spring 82, and the other end extends out of the winding reel 8. Both the winding reel 8 and the telescopic rope reel 7 are provided with corresponding rope outlets 9. The telescopic rope 83 extends to the outside through the rope outlet 9 and passes through the positioning rope ring 51 to connect with the float 6. When the telescopic rope 83 is in the winding state, a stop ball 831 is provided on the telescopic rope 83 outside the corresponding rope outlet 9. The stop ball can prevent the remaining telescopic rope from being wound into the winding reel. The float 6 is connected to the trawl net through the telescopic rope. A total of two telescopic ropes are provided and connected to the bottom of the float to ensure the trawl net is traversed. The float will not tumble on the water surface when the trawl net is lowered. The upper side of the float 6 is equipped with a searchlight ring 64, and a detection device 65 is located at the upper end of the float 6. The float 6 contains a battery 66 that is electrically connected to the detection device 65 and the searchlight ring 64. The float, the searchlight ring on the float, and the detection device are all sealed to prevent water immersion in the water and protect the internal structure. The float also contains a battery 66 that is electrically connected to the detection device 65 and the searchlight ring 64. In order to ensure that the float is always facing downwards in the water, there is a counterweight filling area in the lower shell. The bottom center of the float is equipped with a rope buckle 67 for easy connection of the telescopic rope.
[0024] In this embodiment, the upper pull rope 1 is provided with connecting blocks 11 at both ends. The connecting blocks 11 are fixedly connected to the upper pull rope 1 by screws. The connecting blocks 11 are also provided with a locking slot 12. The pull rope plays the role of lifting the entire trawl net. When performing a rescue operation, external force is transmitted through the pull rope, which can drag or lift the entire trawl net in the water.
[0025] The implementation principle of a life-saving trawl net in this embodiment is as follows: a fiber net formed by multiple intersecting fiber bands is fixed between the upper and lower pull ropes. The upper pull rope serves to lift the entire trawl net. During a rescue operation, external force can drag or lift the entire trawl net in the water by pulling on both ends of the upper pull rope. A lead block is attached to the bottom of the lower pull rope. The lead block's function is to allow the entire trawl net to sink to a certain depth in the water. Due to the high density of the lead block, it will pull the mesh portion downwards under the action of gravity, ensuring that the trawl net has a certain vertical depth distribution in the water. Instead of floating completely on the surface, a mounting plate and a buoy are installed in the middle of the pull rope. The mounting plate has a telescopic rope reel containing a telescopic rope, which connects to the buoy, indirectly linking the buoy to the trawl net. The buoy provides some lifting and support to the central structure of the trawl net. The telescopic rope reel automatically stores and extends the telescopic rope. In different rescue scenarios, such as when the trawl net needs to adapt to different water levels or changes in the distance between the rescued object and the trawl net, the buoy floats on the surface and adjusts according to changes in buoyancy. The retractable rope disc can extend or retract the automatic telescopic rope as needed. The float has a hollow, sealed, and integral internal structure. Furthermore, the float's material density is less than that of water, allowing it to provide buoyancy on the water surface. When the trawl net is launched, the float floats on the surface. As the trawl net continues to sink, the buoyancy exceeds the contraction force of the spring under gravity, causing the telescopic rope to extend. This ensures the float remains afloat and is not pulled underwater by the trawl net. Two telescopic ropes contribute to the overall stability of the float. The float is equipped with a searchlight ring for surface illumination and internal detection devices. The device allows for surface detection, providing timely information about the water's condition. When the trawl net is lifted, the upward force counteracts the buoyancy, and the spring's contraction force exceeds the buoyancy, pulling the telescopic rope into the reel and winding it up along the rope winding channel until the rope is fully reeled in and the trawl net leaves the water. This coordinated movement of the trawl net up and down increases its search and rescue capabilities. Furthermore, a floating platform equipped with a detection device and a searchlight ring on the trawl net allows for clear visibility of the water's condition even during nighttime salvage operations, ensuring the success of the rescue mission and improving rescue and salvage efficiency.
[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
