Description

Technical Field

[0001] The invention relates to the technical field of artificial fish nests, in particular to an artificial fish nest for river ecological purification and restoration. Background Art

[0002] Artificial fish nests are mainly prepared for ornamental fish that produce sticky eggs, so that the eggs can stick to them after fertilization, making it easier to hatch.

[0003] Artificial fish nests generally float on the water surface. When it is raining heavily, raindrops hitting the water surface will wash the fish eggs near the water surface off the fish nest. At the same time, birds outside may prey on the fish eggs near the sleeping position, and other objects from the outside may fall and cause damage to the fish eggs near the water surface on the fish nest, which is not conducive to the ecological restoration of the river. In addition, when a boat passes through the river, the fish nest needs to be moved. When the fish nest is moved, the water in the river will move relative to the fish nest, thereby washing away the fish eggs in the fish nest or the fish nest will collide with other substances in the water, which will affect the hatching of the fish eggs.

[0032] A switching mechanism is provided on the fixing block 2, and the switching mechanism is used to switch the protection mechanism to the side position of the fish nest frame 1;

[0033] The fish nest frame 1 is provided with an expansion mechanism, which is used to expand the protective mechanism switched to the side position by the switching mechanism to protect the side part of the fish nest frame 1, so as to prevent the fish eggs from being washed away by the water flow and hitting other objects in the water when the fish nest frame 1 moves;

[0034] During operation, the fish nest frame 1 is placed in a river channel, and the fish in the river channel can lay eggs in the hatching structure in the fish nest frame 1, and the fish eggs will be attached to the hatching structure; by activating the protective mechanism, the space above the fish nest frame 1 can be protected, which can effectively prevent raindrops from washing away the fish eggs near the water surface during heavy rain, and prevent birds from preying on them or foreign objects from falling and hitting them, thereby effectively ensuring the safety of the fish eggs;

[0035] When a boat passes through the river, the switching mechanism is started, and the protective mechanism can be switched to the side position of the fish nest frame 1 through the switching mechanism, and then the unfolding mechanism is started, and the protective mechanism can be unfolded through the unfolding mechanism to protect the side part of the fish nest frame 1. At this time, the fish nest frame 1 can be pulled. During the movement of the fish nest frame 1, the water in the river moves relative to the fish nest frame 1. Most of the river water can be blocked by the protective mechanism, which can effectively prevent the river water from washing away the fish eggs and prevent some substances in the water from hitting the fish eggs.

[0036] like Figure 3-5 As shown, as a further solution of the present invention, the protective mechanism includes two connecting blocks 3, which are distributed at the front and rear sides of the fixed block 2 and are rotatably connected to the fixed block 2; the front and rear connecting blocks 3 are rotatably connected to the first fixing rod 4 at the left side of the front end and the right side of the rear end, and a second fixing rod 5 is provided behind the front first fixing rod 4 and in front of the rear first fixing rod 4. A folding plate 6 is provided between the first fixing rod 4 and the second fixing rod 5, and the folding plate 6 is fixedly connected to the first fixing rod 4 and the second fixing rod 5; a folding mechanism is provided on the fixed block 2 and the two connecting blocks 3, and the folding mechanism is used to drive the two folding plates 6 to expand and retract;

[0037] The folding mechanism includes two first motors 7 and two slide grooves 8 on the left and right sides of the connecting block 3 and the left and right sides of the fixed block 2; the two first motors 7 are fixedly connected to the left side of the front connecting block 3 and the right side of the rear connecting block 3 respectively; a screw rod 9 is fixedly connected to the output shaft of the first motor 7, and the rear end of the left screw rod 9 and the front end of the right screw rod 9 are rotatably connected to the rotating blocks 10 respectively, and the front and rear rotating blocks 10 are rotatably connected to the connecting blocks 3 on the front and rear sides respectively; a slider 11 is provided on one end of the second fixed rod 5 near the connecting block 3, the slider 11 is engaged with the second fixed rod 5, and the slider 11 is slidably connected to the connecting block 3 and the slide groove 8 on the fixed block 2; the left and right sliders 11 are threadedly connected to the screw rods 9 on the left and right sides respectively;

[0038] During operation, by starting the two first motors 7, the screw rods 9 on the left and right sides can be driven to rotate. When the screw rods 9 on the left and right sides rotate, they will respectively drive the sliders 11 on the left and right sides to slide backward and forward respectively. When sliding, the slider 11 drives the second fixed rod 5 connected thereto to move, and the second fixed rod 5 will drive the folding plate 6 to gradually unfold; when the sliders 11 on the left and right sides slide to the rearmost and frontmost positions respectively, the folding plates on the left and right sides are in the unfolded state and cover the space above the fish nest frame 1, thereby protecting the space above the fish nest frame 1; when the folding plate 6 above the fish nest frame 1 needs to be folded, it is only necessary to start the two first motors 7 to drive the screw rods 9 on the left and right sides to rotate in opposite directions.

[0039] like Figure 5 、 Figure 7-8 As shown, as a further solution of the present invention, the switching mechanism includes two clamping blocks 12, and the two clamping blocks 12 are respectively fixedly connected to one end position of the outer side of the two second fixed rods 5; the bottom position of the fish nest frame 1 is rotatably connected to a rotating ring 13, and the front and rear positions of the rotating ring 13 are rotatably connected to the clamping frames 14, and the two clamping frames 14 are distributed in a circular array on the rotating ring 13; the clamping blocks 12 at the left and right positions can be respectively engaged with the clamping frames 14 on the front and rear sides; the fixed block 2 has a rotatable shaft inside, and the shaft is fixedly connected to the connecting blocks 3 on the front and rear sides;

[0040] During operation, when the folding plate 6 needs to be switched to the side position of the protective fish nest frame 1, the two folding plates 6 are folded up by starting the two first motors 7, and then the shaft in the fixed block 2 is started, and the shaft in the fixed block 2 drives the connecting blocks 3 on the front and rear sides to rotate counterclockwise and clockwise respectively; when the connecting blocks 3 on the front and rear sides are rotated ninety degrees, the connecting blocks 3 on the front and rear sides respectively drive the first fixing rod 4 and the second fixing rod 5 on the front and rear sides to rotate to a vertical state, and the clamping block 12 on the second fixing rod 5 will be clamped in the clamping frame 14, and then the second fixing rod 5 can be driven to move by driving the clamping frame 14 to move, and when the second fixing rod 5 moves, it will drive the folding plate 6 to unfold.

[0041] like Figure 7-8 As shown, as a further solution of the present invention, the unfolding mechanism includes two fixing plates 15, both of which are fixedly connected to the fish nest frame 1; a driving mechanism is provided on the fixing plates 15, and the driving mechanism is used to drive the rotating ring 13 to rotate;

[0042] The driving mechanism includes two second motors 16, which are fixedly connected to the two fixed plates 15 respectively; the upper end of the output shaft of the second motor 16 is fixedly connected to a gear 17; the bottom position of the rotating ring 13 is fixedly connected to an outer ring gear 18, which is meshed with the two gears 17 at the same time;

[0043] The engaging portion between the slider 11 and the second fixing rod 5 is in an arc shape; when the second fixing rod 5 is in a vertical state, the center of the arc portion where the slider 11 and the second fixing rod 5 engage is located on the rotation axis of the rotating ring 13;

[0044] A fixing ring 19 is sleeved on the outer side of the rotating ring 13, and the fixing ring 19 is fixedly connected to the two fixing plates 15; an insertion rod 20 is provided on the outer side of the clamping frame 14, and the insertion rod 20 is slidably connected to the clamping frame 14 and a spring 21 is fixedly connected to the insertion rod 20, and the spring 21 is fixedly connected to the clamping frame 14; a socket 22 is provided on the clamping block 12, and the insertion rod 20 can be plugged into the socket 22; extrusion grooves 23 are provided on the inner side of the fixing ring 19 at the positions of the two insertion rods 20, and the two insertion rods 20 are respectively located in the two extrusion grooves 23; the inner diameter of the fixing ring 19 is smaller than the distance between the two insertion rods 20.

[0045] During operation, when the folding plates 6 on the side need to be unfolded, the two second motors 16 are started, the second motors 16 drive the gear 17 to rotate, the gear 17 drives the outer ring gear 18 to rotate, and the outer ring gear 18 drives the rotating ring 13 to rotate. When the rotating ring 13 rotates, it drives the two clamping frames 14 to rotate with the rotating ring 13. When the clamping frame 14 moves, it pushes the clamping block 12 clamped thereto to move, and the clamping block 12 drives the second fixing rod 5 to move, so that the folding plates 6 in the vertical state begin to unfold; when the rotating ring 13 rotates nearly 180°, the two folding plates 6 can basically cover the side part of the fish nest frame 1;

[0046] When the folding plate 6 that is unfolded on the side needs to be folded, the rotating ring 13 drives the clamping frame 14 to rotate with the rotating ring 13 when it rotates, while the fixed ring 19 remains stationary. Therefore, under the action of the extrusion groove 23 on the fixed ring 19, when the clamping frame 14 moves, the insertion rod 20 will be squeezed to a deeper position in the clamping frame 14. When the insertion rod 20 is inserted into a deeper position in the clamping frame 14, it will be inserted into the insertion hole 22 of the card block 12. Therefore, when the rotating ring 13 is reset, the card block 12 will not be separated from the clamping frame 14. When the rotating ring 13 is fully reset, the insertion rod 20 is at the deepest position in the extrusion groove 23, so that under the action of the spring 21, the insertion rod 20 automatically separates from the card block 12.
