[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The utility model provides a technical solution: a salvage device, including a hollow grip 1 and a scoop net 6, one end of the hollow grip 1 is fixedly connected to a net frame 2, a first clamping block 203 is fixedly connected to the bottom of the net frame 2, a mounting slot 202 is opened in the hollow grip 1, a movable slider 4 is slidably installed in the mounting slot 202, a second clamping block 401 is fixedly connected to the bottom of the movable slider 4, the second clamping block 401 and the first clamping block 203 are respectively fixedly connected to the front and rear upper edges of the scoop net 6, a connecting rod 402 is symmetrically fixedly connected to the back of the movable slider 4, a connecting plate 403 is fixedly connected between the two connecting rods 402, a movable rod 404 is fixedly connected to the back of the connecting plate 403, and the movable rod 404 is slidably installed in the hollow grip 1.

[0024] When the fish enters the scoop net 6, the connecting plate 403 can be driven to move by the moving rod 404, and the connecting plate 403 can be driven to move by the moving slider 4 through the connecting rod 402. The movement of the moving slider 4 will drive the second clamping block 401 to move, so that the second clamping block 401 is continuously moved closer to the first clamping block 203, thereby making the front and rear edges of the scoop net 6 continuously close to each other, so that the opening at the upper end of the scoop net 6 is closed and shrunk, thereby effectively preventing the salvaged fish from escaping.

[0025] Among them, in order to achieve the purpose of supporting both sides of the scooping net 6, this device adopts the following technical solutions: connecting grooves 101 are provided on both sides of the hollow gripping rod 1, and the connecting grooves 101 cooperate with the connecting plates 403. A first limiting recess 102 is provided in the hollow gripping rod 1, and a second return spring 406 is fixed in the first limiting recess 102. The second return spring 406 is sleeved on the moving rod 404, and a second spring pad 405 is fixed on the moving rod 404. The other end of the second return spring 406 is fixed to the second spring pad 405. A limiting slide groove 201 is symmetrically provided in the net frame 2, and a limiting slider 5 is slidably installed in the limiting slide groove 201. The lower end of the limiting slider 5 is fixed with a third clamping block 502, and the third clamping block 502 is fixed to the upper edges of both sides of the scooping net 6. An avoidance hole 501 is provided in the limiting slider 5.

[0026] The two sides of the scooping net 6 are connected by the third clamping block 502 to provide support for the two sides of the scooping net 6 to prevent the two sides of the scooping net 6 from collapsing. At the same time, the limit slider 5 is slidably installed in the limit slide groove 201. During the backward movement of the mobile slider 4, the limit slider 5 will also move backward synchronously to close the opening at the upper end of the scooping net 6. The avoidance hole 501 can avoid interference between the connecting rod 402 and the limit slider 5, so that the connecting rod 402 can smoothly pass through the inside of the net frame 2. The second return spring 406 can provide a certain thrust for the second spring pad 405. The second spring pad 405 will drive the moving rod 404 to move under the thrust, and the movement of the moving rod 404 will drive the moving slider 4 to move backward.

[0027] Among them, in order to achieve the purpose of limiting the movement of the movable rod 404, this device adopts the following technical solutions: a limiter 3 is fixed on the hollow grip rod 1, a second limit recess 301 is provided in the limiter 3, a limit pin 302 is slidably installed in the second limit recess 301, a limit hole 407 is provided in the movable rod 404, the limit hole 407 cooperates with the limit pin 302, a first spring pad 303 is fixed on the limit pin 302, a first return spring 304 is sleeved on the limit pin 302, a pull ring 305 is fixed on the upper end of the limit pin 302, and a rubber push block 408 is fixed on the other end of the movable rod 404.

[0028] The first return spring 304 can provide a certain thrust for the first spring pad 303. The first spring pad 303 will drive the limit pin 302 to insert into the limit hole 407 under the thrust, thereby limiting the movement of the movable rod 404. The pull ring 305 can be used to drive the limit pin 302 to move out of the limit hole 407. At this time, the movable rod 404 will move backward quickly without restriction under the push of the second return spring 406, thereby quickly driving the movable slider 4 to move backward to close the upper end opening of the scoop net 6, thereby reducing the time required to close the scoop net 6. The rubber push block 408 makes it convenient for the operator to push the movable rod 404 to reset.

[0029] The working principle and usage process of the present invention are as follows: when in use, it is necessary to hold the hollow grip rod 1 to extend the net frame 2 together with the scooping net 6 into the water to scoop aquatic organisms. When the aquatic organisms enter the scooping net 6, pulling the pull ring 305 can drive the limit pin 302 to move out of the limit hole 407. At this time, the moving rod 404 will move backward quickly without restriction under the push of the second return spring 406, and then quickly drive the moving slider 4 to move backward. The movement of the moving slider 4 will drive the second clamping block 401 to move, so that the second clamping block 401 continues to approach the first clamping block 203, and then the front and rear edges of the scooping net 6 continue to approach, and the opening at the upper end of the scooping net 6 is gradually closed and reduced to prevent the fish from escaping from the inside of the scooping net 6.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
