Description

Technical Field

[0001] The utility model relates to the technical field of fishery aquaculture equipment, and particularly relates to a multi-channel fry counter. Background Art

[0002] A fry counter is a device used to automatically or semi-automatically count the number of fry in a water area. The fry counter usually uses a camera or other sensor devices to capture images of the fry in the water area. This can be achieved through different optical systems, including single or multi-view imaging. The counter records the processed data and provides a user-readable counting result. These results can be presented to the user through an interface, a report, or other means.

[0003] Chinese Patent with application number CN202211628597.5 discloses a fry counting system and a counting method based on the fry counting system, including a water pump 1, a nozzle 2, an ultrasonic distance detection sensor 3, a rubber sheet 4, a belt 5 with a baffle, a camera 6, a photoelectric sensor 7, a counted fry collection bin 8, a screw rod and a fish baffle 9, a motor 10, and a fry collection bin 11 before counting; applying this technical solution can replace manual counting, and can be used for counting different types of fry, with simple use and being safe and reliable.

[0004] When the fry counter counts the fry, since there are often phenomena of fry overlapping or piling up in the channel, the fry counter has inaccurate counting. At the same time, if there is a situation of piling up and jamming the fish, the counting efficiency is not high. Summary of the Utility Model

[0005] Aiming at the above defects or improvement requirements of the prior art, the utility model provides a multi-channel fry counter. The utility model improves the counting accuracy through the structural design of multiple channel baffles; the utility model can make the fry be shunted one by one by the shunt plate with an arc structure without damaging the fry, and will not cause piling up phenomena, thereby improving the fry counting efficiency.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A multi-channel fry counter includes a box body. A stepped support frame is fixed inside the box body. An inlet fish channel, a counting channel, and an outlet fish channel are placed on the top of the stepped support frame through brackets. The inlet fish channel, the counting channel, and the outlet fish channel are sequentially connected and communicated; a counter body is also fixedly connected to the stepped support frame, and the probe of the counter body extends into the counting channel.

[0008] An anti-reflection groove is provided in the counting channel. A plurality of channel baffles are fixed on the inner bottom surface of the anti-reflection groove. The plurality of channel baffles divide the anti-reflection groove into channels with the same distance; the height of the channel baffles gradually decreases from the middle to both sides; an insertion port is left at one end of the anti-reflection groove close to the fish inlet channel. One end of the anti-reflection groove is inserted outside one end of the fish inlet channel, and the other end of the anti-reflection groove is inserted inside one end of the fish outlet channel;

[0009] The upper half of one end of the fish inlet channel close to the anti-reflection groove is closed by a closing plate, and a plurality of flow dividing plates are uniformly fixed on the lower half. The flow dividing plates are in one-to-one correspondence and abut against the channel baffles. The end of the flow dividing plate away from the channel baffle is an arc structure.

[0010] Further, a water inlet is provided on one side of the box body. A water tank is also placed on the stepped support frame. The water inlet end of the water tank is communicated with the water inlet, and the water outlet end of the water tank is communicated with the fish inlet channel; branch water pipes are communicated on both sides of the water tank. The branch water pipes are correspondingly communicated with one side of the fish inlet channel close to the anti-reflection groove. Valves are correspondingly installed on the branch water pipes, and the valves pass through the box body and are arranged outward.

[0011] Further, a fish inlet is provided on the top of the box body. The fish inlet is communicated with the fish inlet channel; one side of the top of the box body is a slope structure. The counter body is electrically connected with a display screen, and the display screen is installed on the slope structure.

[0012] Further, a fish outlet is provided on one side of the box body. The fish outlet channel passes through the fish outlet and extends outside the box body.

[0013] Further, the top surface of the counting channel is a convex pyramid structure, and the counter body extends into the counting channel from the top end of the pyramid structure.

[0014] Furthermore, an opening is provided on the bottom surface of the counting channel. A support inclined plate is provided below the opening. The support inclined plate is placed on the stepped support frame and abuts against the bottom surface of the counting channel.

[0015] Further, a bottom plate is installed at the bottom of the box body. A plurality of casters are provided at the bottom of the box body. The casters pass through the bottom plate and are fixedly connected with the stepped support frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) Through the structural design of multiple channel baffles, the fry in the fish inlet channel can be diverted when flowing into the counting channel, forming multiple channels, which can effectively prevent the fry from piling up together and causing inaccurate counting of the counter body. At the same time, through the structural design that the height of the channel baffle gradually decreases from the middle to both sides, the channel baffle will not block the fry and affect the counting of the counter body, ultimately improving the counting accuracy.

[0018] (2) In the present utility model, the upper half of one end of the fish inlet channel close to the anti-reflection groove is closed by a closing plate, so that the outlet of the fish inlet channel can limit the fry, preventing too many fry from flowing into the counting channel at one time and causing inaccurate counting due to fry stacking. The arc-shaped diversion plate can divert the fry one by one without damaging the fry. If too many fry pile up on one side of the closing plate, resulting in uneven diversion, by opening the valve of the corresponding side branch water pipe, the water flow impacts the side with more fry, washing the fry to the other side, so that the fry flow out evenly in the fish inlet channel without causing stacking, improving the efficiency of fry counting.

[0019] (3) Through the plug-in connection method in cooperation with the anti-reflection groove, water leakage in the channel can be prevented, saving complex installation procedures and facilitating equipment maintenance by the staff. Through the structural design of the pyramid structure and the anti-reflection groove, the counter body can better count the fry in the channel. At the same time, by setting an opening at the bottom of the counting channel and cooperating with the abutment of the supporting inclined plate, when fish get stuck in the anti-reflection groove, the supporting inclined plate can be moved away to shake the anti-reflection groove to make the fry flow away smoothly and prevent fish from getting stuck. When operating normally, the supporting inclined plate can also play a supporting role to improve stability. Description of the Drawings

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment

[0032] As Figures 1 to 8 shown, a multi-channel fry counter includes a box body 100, a stepped support frame 200 is fixed inside the box body 100, a fish inlet channel 400, a counting channel 600 and a fish outlet channel 800 are placed on the top of the stepped support frame 200 through brackets, and the fish inlet channel 400, the counting channel 600 and the fish outlet channel 800 are connected in sequence and communicated; a counter body 500 is also fixedly connected to the stepped support frame 200, and the probe of the counter body 500 extends into the counting channel 600;

[0033] In this embodiment, fry enter from the fish inlet channel 400. When the fry pass through the counting channel 600, the probe of the counter body 500 counts the fry in the counting channel 600, and after counting, the fry flow out from the fish outlet channel 800. It should be noted that the counter body 500 is an existing mature technology, such as devices like Bioscanner counter, which can count fry and will not be elaborated here.

[0034] An anti-reflection groove 700 is provided inside the counting channel 600. A plurality of channel baffles 710 are fixed on the inner bottom surface of the anti-reflection groove 700. The plurality of channel baffles 710 divide the anti-reflection groove 700 into channels with the same distance; the height of the channel baffles 710 gradually decreases from the middle to both sides; one end of the anti-reflection groove 700 close to the fish inlet channel 400 is provided with an insertion port. One end of the anti-reflection groove 700 is inserted outside one end of the fish inlet channel 400, and the other end of the anti-reflection groove 700 is inserted inside one end of the fish outlet channel 800;

[0035] Through the structural design of the plurality of channel baffles 710 of the present utility model, the fry in the fish inlet channel 400 can be shunted when flowing into the counting channel 600, forming a plurality of channels, thereby effectively preventing the fry from accumulating together and causing inaccurate counting of the counter body 500; at the same time, through the structural design that the height of the channel baffles 710 gradually decreases from the middle to both sides, the channel baffles 710 will not block the fry and affect the counting of the counter body 500, and finally improve the counting accuracy.

[0036] The upper half of one end of the fish inlet channel 400 close to the anti-reflection groove 700 is closed by a closing plate 410, and a plurality of flow dividing plates 420 are uniformly fixed on the lower half. The flow dividing plates 420 are in one-to-one correspondence and abut against the channel baffles 710, and the end of the flow dividing plate 420 away from the channel baffle 710 is an arc structure.

[0037] Through the upper half of one end of the fish inlet channel 400 close to the anti-reflection groove 700 being closed by the closing plate 410, the outlet of the fish inlet channel 400 can limit the fry, and prevent too many fry from flowing into the counting channel 600 at one time, resulting in inaccurate counting due to fry stacking. The arc-shaped flow dividing plates 420 can shunt the fry one by one without damaging the fry.

[0038] Further, a water inlet 120 is provided on one side of the box body 100. A water tank 300 is also placed on the stepped support frame 200. The water inlet end of the water tank 300 is communicated with the water inlet 120, and the water outlet end of the water tank 300 is communicated with the fish inlet channel 400; branch water pipes 310 are communicated on both sides of the water tank 300, and the branch water pipes 310 are correspondingly communicated with one side of the fish inlet channel 400 close to the anti-reflection groove 700. Valves 320 are correspondingly installed on the branch water pipes 310, and the valves 320 pass through the box body 100 and are arranged outward.

[0039] The water tank 300 is supplied with water through the connection between an external water source and the water inlet 120. At the same time, through the connection between the water tank 300 and the fish inlet channel 400, the water tank 300 supplies water to the fish inlet channel 400 to create a water curtain flow, enabling the fry to flow smoothly and preventing the fry from getting stuck in the channel.

[0040] If too many fry accumulate on one side of the closing plate 410, resulting in uneven flow diversion, by opening the valve 320 of the corresponding side branch water pipe 310, the water flow impacts the side with more fry, washing the fry to the other side, so that the fry flow out evenly in the fish inlet channel 400 without causing accumulation, improving the efficiency of fry counting.

[0041] It should be noted that the valve 320 can be installed on the branch water pipe 310 inside the water tank 300 or on the branch water pipe 310 outside the water tank 300; when the valve 320 is installed on the branch water pipe 310 inside the water tank 300, the valve 320 can be arranged outward through the water tank 300 and the box body 100 by means of a sealed connection, which will not be elaborated here.

[0042] Furthermore, a fish inlet 110 is provided at the top of the box body 100, and the fish inlet 110 is communicated with the fish inlet channel 400; one side at the top of the box body 100 is a slope structure 150, the counter body 500 is electrically connected with a display screen 510, and the display screen 510 is installed on the slope structure 150.

[0044] Furthermore, a fish outlet 130 is provided on one side of the box body 100, and the fish outlet channel 800 passes through the fish outlet 130 and extends outside the box body 100.

[0045] Furthermore, the top surface of the counting channel 600 is a convex pyramid structure 610, and the counter body 500 extends into the counting channel 600 from the top end of the pyramid structure 610.

[0046] Even further, an opening is provided at the bottom surface of the counting channel 600, and a support inclined plate 900 is provided below the opening. The support inclined plate 900 is placed on the stepped support frame 200 and is in contact with the bottom surface of the counting channel 600.

[0047] Through the insertion method in cooperation with the anti-reflection groove 700, the present utility model can prevent water leakage in the channel, saving complex installation procedures and facilitating equipment maintenance by staff. Through the structural design of the pyramid structure 610 and the anti-reflection groove 700, the counter body 500 can better count the fry in the channel. At the same time, by setting an opening at the bottom of the counting channel 600 and cooperating with the abutment of the support inclined plate 900, when the anti-reflection groove 700 gets stuck with fish, the support inclined plate 900 can be moved away to shake the anti-reflection groove 700 so that the fry can flow away smoothly, preventing fish from getting stuck. When operating normally, the support inclined plate 900 can also play a supporting role to improve stability.

[0048] It is worth noting that an anti-reflection coating is provided in the groove of the anti-reflection groove 700 to reduce light reflection, prevent specular reflection from interfering with imaging, and improve the contrast and clarity of the image after imaging of the counter body 500.
