[0044] Fries are added from the upward port of the fish inlet channel 400, and the fries flow into the counting channel 300 and the fish outlet channel 200 in sequence. When passing through the counting channel 300, the counter body 700 counts the fries, and after counting, the fries finally flow out from the fish outlet channel 200.

[0045] Through the structural design of the outer edge and the inner edge, the channels can be inserted into each other without falling apart.

[0046] It is worth noting that the counter body 700 is an existing mature technology, such as devices like the Bioscanner counter, which can count fries. At the same time, the counter body 700 can be powered by an external power supply, and details are not described here.

[0047] Furthermore, two first n-shaped slides 130 are symmetrically and fixedly connected to the middle of the base 100. First sliding blocks 360 are fixedly arranged on the sides of the counting channel 300. The first sliding blocks 360 are located in the corresponding first n-shaped slides 130 and are slidably connected to the first n-shaped slides 130. At one end of the base 100 away from the rotating groove 120, two second n-shaped slides 140 are symmetrically and fixedly connected.

[0048] Even further, a pair of earpieces 340 are fixedly connected to the bottom of the counting channel 300. A transmission gear 341 is rotatably connected to the earpieces 340. A first toothed plate 220 is fixedly connected to the bottom of the fish outlet channel 200.

The first toothed plate 220 is located above the transmission gear 341 and meshes with the transmission gear 341. The second toothed plate 450 is located below the transmission gear 341 and meshes with the transmission gear 341. A support frame 350 is also fixedly connected to the bottom of the counting channel 300. The second toothed plate 450 is located in the support frame 350 and abuts against the support frame 350.

[0049] By means of the sliding connection between the fish inlet channel 400, the counting channel 300 and the fish outlet channel 200, the present invention enables the channels to be telescopic without the risk of water leakage. By cooperating with the first n-shaped slide 130 and the second n-shaped slide 140, the fish inlet channel 400, the counting channel 300 and the fish outlet channel 200 can be telescopically extended in equal proportion. At the same time, through the meshing of the first toothed plate 220, the second toothed plate 450 and the transmission gear 341, the fish inlet channel 400, the counting channel 300 and the fish outlet channel 200 can be telescopically extended smoothly, reducing the interference to the fry, thereby better protecting the fry and reducing the counting error of the fry by the counter body 700.

[0050] Even further, the limiting structure 600 includes a rotating shaft 620. A rope shaft 610 is fixedly connected to the rotating shaft 620. One end of the base 100 close to the second n-shaped slide 140 is fixedly connected to a support plate 150. One end of the rotating shaft 620 is rotatably connected to the support plate 150 through a bearing. The other end of the rotating shaft 620 is fixedly connected to a cross bar 622. One end of the cross bar 622 is fixedly connected to a rotating handle 623.

[0051] A through hole is formed at the top of the second n-type slideway 140. Transmission steel ropes 611 are fixedly connected to the second sliding blocks 431 respectively. The transmission steel ropes 611 pass through the corresponding through holes and are fixedly wound around the rope shaft 610. The winding directions of the two transmission steel ropes 611 are opposite.

[0052] Furthermore, the rotating shaft 620 has a hollow structure. A limiting shaft 630 is movably inserted into the rotating shaft 620. Two through grooves 621 are symmetrically formed on the side wall of the rotating shaft 620 between the support plate 150 and the rope shaft 610. Fixed rods are symmetrically arranged on the side wall of the limiting shaft 630. The fixed rods pass through the corresponding through grooves 621 and are fixedly connected to a limiting ring 631 together.

[0053] Furthermore, a plurality of second rotating grooves are evenly formed on the outer side surface of the limiting ring 631. A clamping strip 633 is rotatably connected to the second rotating groove through a bearing. A torsion spring is arranged in the second rotating groove. The torsion spring is fixedly connected to the second rotating groove and the clamping strip 633 respectively; An abutting block 632 is fixedly connected to one side of the second rotating groove; The outer end of the clamping strip 633 has a curved surface structure;

[0054] A clamping groove 151 is formed on the side wall of the support plate 150 close to the rope shaft 610. A plurality of limiting protrusions are evenly and continuously arranged on the inner side wall of the clamping groove 151. The limiting protrusions have a curved surface structure;

[0055] When the limiting ring 631 is located in the clamping groove 151, the curved surface of the clamping strip 633 abuts against the curved surface of the limiting protrusion and has the same curved surface direction; When the rope shaft 610 is rotated to raise the second sliding block 431, the curved surface of the clamping strip 633 slides on the curved surface of the limiting protrusion in the clamping groove 151 through the rotation of the torsion spring; When the rope shaft 610 is released, the limiting ring 631 rotates in the opposite direction to reset the torsion spring, and the clamping strip 633 abuts against the abutting block 632, so that the clamping strip 633 is clamped between the adjacent limiting protrusions in the clamping groove 151, thereby performing limiting and fixing.

[0056] In the present invention, through the design of the limiting structure 600, when it is necessary to lift and elongate the channel, the limiting shaft 630 is pushed to make the limiting ring 631 enter the clamping groove 151, and the curved surface of the clamping strip 633 abuts against the curved surface of the limiting protrusion and has the same curved surface direction; by shaking the rotating handle 623, the transmission steel rope 611 is wound around the rope shaft 610 to lift the second sliding block 431, and then the channel is lifted and elongated; due to the action of the torsion spring, the curved surface of the clamping strip 633 will slide on the curved surface of the limiting protrusion of the clamping groove 151, so that the clamping groove 151 does not affect the rope winding of the rope shaft 610; when the channel has reached the specified position, the rope shaft 610 is released. At this time, due to the gravity of the channel, the rope shaft 610 will be driven to rotate in the reverse direction, which drives the limiting ring 631 to rotate in the reverse direction to reset the torsion spring. At this time, after the torsion spring is reset, the clamping strip 633 rotates and abuts against the abutting block 632, and the outer end of the clamping strip 633 is stuck between the adjacent limiting protrusions of the clamping groove 151. Since the clamping groove 151 is fixed, the gravity of the channel acts on the abutting block 632, the clamping strip 633 and the clamping groove 151, and it will not fall off, so as to carry out limiting and fixing; when it is necessary to lower the channel, only need to pull the limiting shaft 630 to move the limiting ring 631 out of the clamping groove 151, and then shake the rotating handle 623 in the reverse direction; through the structural design of the limiting structure 600 in the present invention, the device can be better fixed, the operation is simple, the channel can stop at the position where it wants to stay, and the device adjustment is more flexible.

[0057] Further, a water tank 500 is fixedly connected to the side surface of the fish inlet channel 400 away from the second outer edge 420. The top of the water tank 500 is open, and a plurality of water inlet holes 520 are horizontally and evenly opened at the lower end of the side wall of the water tank 500. The water inlet holes 520 are communicated with the fish inlet channel 400;

[0058] Furthermore, slot holes 540 are symmetrically arranged inside the water tank 500, and a throttling structure is inserted into the slot holes 540. The throttling structure includes a throttling plate 550. The throttling plate 550 is inserted into the slot holes 540, and one side surface of the throttling plate 550 abuts against the inner wall of the water tank 500; a plurality of through holes 551 are opened on the side surface of the throttling plate 550, and the through holes 551 correspond to the water inlet holes 520 one by one; the inside of the throttling plate 550 is a hollow structure, and a control plate 560 is inserted through the inside of the throttling plate 550. A plurality of throttling holes 561 are opened on the control plate 560, and the throttling holes 561 correspond to the through holes 551 one by one; two sealing connection grooves 530 are symmetrically opened on the side wall of the water tank 500, and the control plate 560 passes through the corresponding sealing connection grooves 530 and extends out of the water tank 500.

[0059] Through the structural design of the water tank 500, through the mutual cooperation of the throttle plate 550 and the control plate 560, the water inlet hole 520 can flexibly adjust the water inlet flow rate. It only needs to pull the control plate 560. At the same time, with the height adjustment of the channel, the fry can pass through the counting channel 300 at a suitable speed, preventing the speed from being too fast or too slow, facilitating the fry counting, and further improving the accuracy of fry counting. At the same time, the porous design makes the water flow of the device more uniform, thus forming a stable water flow and improving the stability of the speed.

[0060] Furthermore, sealing strips are provided at the connections between both ends of the throttle plate 550 and the water tank 500. The sealing connection groove 530 can also be sealed through a sealing strip.

[0061] Through the structural design of the control plate 560 and the throttle plate 550, the device reduces the risk of water leakage while controlling the flow rate. At the same time, the use of sealing strips makes the device achieve a multiple sealing effect.

[0062] Further, a pulley 160 is installed at the bottom of the base 100, and a handle 170 is fixedly connected to the outer wall of the second n-shaped slideway 140. The movement of the counter device can be better controlled through the pulley 160 and the handle 170.
