[0019] 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 described embodiments 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 creative work are within the scope of protection of the present invention.
[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Reference Figure 1-4 The present invention provides a device for catching fish samples, comprising:
[0022] A floating plate 1 is rotatably connected to a flat plate 2, a spring 3 is arranged between the flat plate 2 and the floating plate 1, and the spring 3 keeps the floating plate 1 and the flat plate 2 in a horizontal state. A straight rod 4 is rotatably connected to the floating plate 1, a plurality of first positioning holes 5 are opened on the floating plate 1, a second positioning hole is opened on the straight rod 4, and a positioning pin 6 is inserted into the first positioning hole 5 and the second positioning hole. Two first rings 7 are fixedly connected to the flat plate 2, a first rope 8 is fixedly connected between the two first rings 7, and a plurality of second rings are fixedly connected to the straight rod 4 9 and baffle 10, a U-shaped rod 11 is passed through the second ring 9, the U-shaped rod 11 has a first end 12 and a second end 13, a connecting column 14 is fixedly connected to the straight rod 4, the baffle 10 is located at the first end 12, an elastic rope 15 is fixedly connected between the second end 13 and the connecting column 14, a connecting column 2 16 is fixedly connected to the straight rod 4, the connecting column 2 16 is used to connect with the fishing net 24, a pull rope 17 is fixedly connected to the U-shaped rod 11, and the first rope 8 is detachably connected to the first end 12.
[0023] In this device, the floating plate 1 can make the device float on the water surface. The material of the straight rod 4 is preferably wood. This device requires two people to operate. The method of use is as follows:
[0024] 1. Connect the fishing net 24 to the second connecting column 16, and connect the pull rope 17 to the bend of the U-shaped rod 11;
[0025] Second, rotate the plate 2 to make it vertical, pull the U-shaped rod 11, and make the first end 12 withdraw from the second ring 9 that is close to it. At this time, the elastic rope 15 is stretched, and then put the first rope 8 on the first end 12 of the U-shaped rod 11, loosen the U-shaped rod 11, and make the first end 12 pass through the second ring 9 that has just been withdrawn. In this way, the first rope 8 can be connected to the U-shaped rod 11;
[0026] 3. One staff member pulls one end of the pull rope 17 and puts the device into the water. Another staff member holds a fishing net, stands in shallow water, and slowly releases the fishing net. Due to the buoyancy of the floating plate 1, the device will float on the water surface. The flat plate 2 is in a vertical state. Under the action of the water flow, the flat plate 2 will make the device float farther and drift to a deeper water position.
[0027] Fourth, when the fishing net is completely released, pull the drawstring 17 once, and the first end 12 of the U-shaped rod 11 will withdraw from the adjacent second ring 9. Since the plate 2 is subjected to the elastic force of the spring 3, the first rope 8 will quickly detach from the first end 12, so that the plate 2 is in a horizontal state, and one end of the drawstring 17 can be fixed on the shore. The fishing net 24 will be curved under the action of the water flow, and the net hanging is completed.
[0028] In the present device, the angle between the straight rod 4 and the floating plate 1 can be adjusted to adjust the floating direction of the present device in the water. When adjusting, the positioning pin 6 is pulled out, and then the straight rod 4 is rotated, and then the positioning pin 6 is inserted into the first positioning hole 5 and the second positioning hole; the baffle 10 is used to block the U-shaped rod 11.
[0029] A further optimized solution is that a plurality of sleeves 18 are fixedly connected to the floating plate 1 , a first rotating shaft 19 is fixedly connected to the straight plate, the first rotating shaft 19 is passed through the sleeves 18 , the first rotating shaft 19 is rotatably arranged in the first sleeve 18 , and the spring 3 is installed on the first rotating shaft 19 .
[0030] The rotation connection of the first rotating shaft 19 and the sleeve 18 enables the flat plate 2 and the floating plate 1 to be rotationally connected.
[0031] According to a further optimized solution, a first connecting hole is provided on the floating plate 1, a second connecting hole is provided on the straight rod 4, a second rotating shaft 20 is passed through the first connecting hole and the second connecting hole, and the second rotating shaft 20 is rotatably arranged in the first connecting hole and the second connecting hole.
[0032] The floating plate 1 and the straight rod 4 are rotatably connected via a second rotating shaft 20 .
[0033] According to a further optimized solution, a third ring 21 is fixedly connected to the second end 13 , and the elastic rope 15 is fixedly connected to the third ring 21 .
[0034] The third ring 21 is used to connect the elastic rope 15 and the U-shaped rod 11 .
[0035] According to a further optimized solution, a top plate 22 is fixedly connected to the connecting column 14 .
[0036] The top plate 1 22 prevents the elastic cord 15 from falling out.
[0037] According to a further optimized solution, a second top plate 23 is fixedly connected to the second connecting column 16 .
[0038] The second top plate 23 prevents the connecting rope connected to the fishing net 24 from falling out.
[0039] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
