Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding, in particular to an anti-escape fish blocking net used for fish breeding. Background Art

[0002] Fish-blocking nets generally refer to nets laid at the mouth of fish-breeding bays or gates to prevent farmed fish from escaping. In river fish farming, in order to prevent the escape of artificially bred fish and cause economic losses, fish-blocking nets are often set up in the river to prevent fish from escaping.

[0003] Most of the existing fish blocking nets are directly placed in the water. Although they can block fish in the water and on the water at the same time, when the water level in the river rises, the water will overflow the fish blocking net, causing some fish to escape with the water flow. Another part of the fish blocking net uses floating objects to make the top of the fish blocking net float with the water, which can adapt to the changes in different water levels. Although it is not easy to overflow with water, fish will jump out of the water due to the effects of escape, light, waves, lack of oxygen and habits. Some fish will escape from the breeding area from the water, resulting in poor applicability of the existing fish blocking nets, causing losses to farmers. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4As shown, an anti-escape fish blocking net for fish farming comprises a blocking net 1, which can block fish in the water to prevent the fish from swimming out of the farming range. The bottom of the blocking net 1 is fixedly connected with a sinker 2, which can make the bottom of the blocking net 1 droop naturally, thereby preventing the fish from swimming out of the bottom of the blocking net 1, and can also cooperate with other fixed placements to block the bottom of the blocking net 1. A mounting block 3 is arranged on one side above the surface of the blocking net 1, and a fixing block 4 is arranged on the other side above the surface of the blocking net 1. Both the mounting block 3 and the fixing block 4 are designed as a quarter sphere, and the mounting block 3 and the fixing block 4 are used in combination. The material of the mounting block 3 and the fixing block 4 are both iron, under this effect, the mounting block 3 can be made 3 and the fixed block 4 can form a hemisphere after being spliced, thereby lowering the center of gravity of the mounting block 3 and the fixed block 4, which is convenient for subsequent use. A mounting groove 5 is provided on one side of the mounting block 3, and a movable rod 6 is slidably connected to the inner wall of the mounting groove 5. A connecting block 7 is fixedly connected to one of the two sides of the movable rod 6. A connecting groove 8 is provided on one side of the fixed block 4, and the movable rod 6 and the connecting block 7 are both slidably connected to the inner wall of the connecting groove 8. Under this action, the movable rod 6 and the connecting block 7 can be inserted into the interior of the connecting groove 8, and then the movable rod 6 can be rotated to rotate the connecting block 7, so that the connecting groove 8 and the connecting block 7 block each other, so that the mounting block 3 and the fixed block 4 are connected, which is more convenient. The inner cavity of the mounting groove 5 is installed with an auxiliary mechanism 9, and the auxiliary mechanism 9 is installed with an auxiliary mechanism 9. The auxiliary mechanism 9 can facilitate the staff to move the movable rod 6, and can further limit the connecting block 7 so that it will not easily break away from the inside of the connecting groove 8. A positioning block 14 is fixedly connected to one side of the fixing block 4, and a positioning groove 15 is provided on one side of the mounting block 3. The positioning block 14 cooperates with the positioning groove 15 to enable the mounting block 3 and the fixing block 4 to squeeze the blocking net 1, so as to enhance the fixing effect of the blocking net 1. The tops of the mounting block 3 and the fixing block 4 are fixedly connected with floating plates 10. The floating plates 10 are designed with hard foam material, and the top areas of the two floating plates 10 are larger than the top areas of the mounting block 3 and the fixing block 4. The mounting block 3 and the fixing block 4 can be made to float on the water surface, so that the blocking net 1 can change its position according to the height of the water level, so that the fish blocking net can be suitable for water bodies of different depths, and with the cooperation of the floating board 10, the mounting block 3 and the fixing block 4, the center of gravity can be lowered, so that the floating board 10 will not flip easily, thereby making the floating board 10 more stable. The top of one side of the floating board 10 is fixedly connected with a vertical pole 11, and one side of the vertical pole 11 is fixedly connected with a connecting net 12. A blocking mechanism 13 is installed at the bottom of the connecting net 12. The blocking mechanism 13 can block the gap between the connecting net 12 and the blocking net 1, thereby preventing fish from escaping from the gap between the blocking net 1 and the connecting net 12.

[0022] The auxiliary mechanism 9 includes a connecting ring 91, the inner wall of which is fixedly connected to the surface of the movable rod 6, and a compression spring 92 is movably connected to one side of the connecting ring 91, and one end of the compression spring 92 is fixedly connected to the inner wall of the mounting groove 5. A locking groove 93 is provided on the inner wall of the connecting groove 8, and the inner wall of the locking groove 93 is slidably connected to the surface of the connecting block 7. Under this action, after the connecting block 7 is rotated inside the connecting groove 8, the position of the connecting block 7 corresponds to the position of the locking groove 93. Under the action of the compression spring 92, the connecting block 7 can be embedded in the locking groove 93, thereby limiting the connecting block 7, so that the connecting block 7 will not move at will, and the fixing effect of the mounting block 3 and the fixing block 4 is effectively improved.

[0023] The blocking mechanism 13 includes a blocking net 131, the top of which is fixedly connected to the bottom of the connecting net 12, a magnet 132 is fixedly connected to the upper part of one side of the blocking net 131, an iron block 133 is embedded in the top of the blocking net 1, the magnet 132 and the iron block 133 are used together, under which the connecting net 12 and the blocking net 131 can be connected, a lead sinker 134 is fixedly connected to the bottom of the blocking net 131, under the action of the lead sinker 134, the blocking net 131 can be naturally vertical, so that the blocking net 131 overlaps with the blocking net 1, thereby blocking the gap and increasing the blocking effect on fish.

[0024] Working principle: first, fix both sides of the blocking net 1 on the shore, then limit the bottom of the blocking net 1, then the staff passes the movable rod 6 through the blocking net 1, so that the movable rod 6 drives the connecting block 7 to enter the inside of the connecting groove 8, and then rotates the movable rod 6 to drive the connecting block 7 to rotate, and under the action of the compression spring 92, the connecting block 7 can be embedded in the inside of the positioning groove 93 through the cooperation of the connecting ring 91 and the movable rod 6, so as to limit the connecting block 7, and then under the cooperation of the mounting block 3 and the fixing block 4 and the floating board 10, the mounting block 3 and the fixing block 4 are located below the water surface, and the floating board 10 floats on the water surface, so that the vertical pole 11 and the connecting net 12 can stand up, and under the cooperation of the mounting block 3 and the fixing block 4 and the floating board 10, the center of gravity is low, and the connecting net 12 will not easily fall over. Under the action of the blocking net 1, the fish in the water are blocked, and under the cooperation of the floating board 10, the connecting net 12 is higher than the water surface, which can block the fish jumping out of the water, effectively improving the blocking effect on the fish.
