Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of factory circulating water aquaculture system, and particularly relates to an intelligent dead fish cleaning system based on video monitoring for factory circulating water aquaculture. BACKGROUND

[0002] Dead fish is inevitable in the process of factory circulating water aquaculture, but if it is not removed in time, it will rot and affect the water quality and pollute the water body; at the same time, it will also breed harmful substances such as bacteria and spread other healthy fish groups.

[0003] At present, the collection of dead fish mainly relies on manual fishing, which is difficult to operate and has high labor intensity, and at the same time, the human disturbance behavior in the process will also affect the feeding effect of other fish groups, especially the fish groups that like quiet environment. As for turbid water, the human being cannot distinguish the dead fish and cannot complete the fishing work of the dead fish in the first time, the fish body has already rotted, the bacteria have already begun to spread to other healthy fish groups, and the loss is that similar dead fish situation will also occur.

[0004] Most of the current dead fish collection devices refer to foreign technology design to use water pressure to remove dead fish devices, and still need manual operation of the switch (the human being needs to find the dead fish in the first time), the dead fish is removed out of the pool by the cylinder driving the lifting rod to lift the sleeve pipe to make the dead fish mouth leak out, and the dead fish is flushed out of the pool by the water flow; in addition, the device using the pipe pulling to form a liquid level difference to remove the dead fish can provide a larger suction force in an instant, but the suction force is not persistent with the water level falling, resulting in that some dead fish cannot be removed with the water flow; the above similar dead fish removal devices all have the following problems: (1) the human being needs to find the dead fish in the first time and touch the operation switch (cylinder, pipe pulling, negative pressure, etc.), which is difficult to find and realize in time for turbid water; (2) the time for removing the dead fish is in a minority, and the normal collection work of residual feed and feces is not considered when there is no dead fish to remove; (3) the similar device has the problems of high construction difficulty and high maintenance cost. SUMMARY

[0005] To solve the above problems, the present application proposes an intelligent dead fish cleaning system based on video monitoring for factory circulating water aquaculture, which can find the dead fish in the first time through underwater video monitoring, and the mechanization degree is improved and the labor is greatly reduced.

[0008] Further, the servo-reduction motor transmission device comprises a servo-reduction motor, a fixed base, a transmission shaft and a fish passing module, the servo-reduction motor is fixed on the top of the extension pipe through the fixed base, the servo-reduction motor is connected with the fish passing module arranged below through the transmission shaft, the fish passing module is in a cylindrical shape, the top of the fish passing module is hollow, two first fish passing openings are symmetrically arranged on the side surface of the fish passing module, two second fish passing openings are symmetrically arranged on the bottom of the extension pipe, and the fish passing channel is formed when the first fish passing openings overlap with the second fish passing openings.

[0009] Further, the system further comprises an underwater video monitoring system, the underwater monitoring system comprises an underwater camera and an information acquisition computer, the underwater camera is used for acquiring the image of the bottom of the pool, the information acquisition computer processes the image shot by the underwater camera to detect the number and size data of the dead fish, and the control system controls the servo-reduction motor transmission device to control the opening time of the fish passing channel.

[0010] Further, the underwater camera transmits real-time pictures to the information acquisition computer, the information acquisition computer processes the real-time pictures by using deep learning technology, and calculates the number (N) of the dead fish, the average length (L, unit: cm) of the dead fish and the average width (W, unit: cm) of the dead fish.

[0011] Further, the opening time T (unit: second) of the fish passing channel controlled by the servo-reduction motor transmission device is as follows:

[0012]

[0013] The application has the following beneficial effects:

[0014] 1. The underwater video monitoring system can timely find the dead fish and timely remove and collect the dead fish, and the timely removal and collection of the dead fish are not affected by the turbidity of the culture water.

[0015] 2. With the design of the servo geared motor transmission device, there is no need for manual operation of the touch switch (cylinder, tube pulling, negative pressure, etc.), which will greatly improve the degree of mechanization and automation, greatly reduce labor costs, save a lot of time, and the servo geared motor transmission device has low energy consumption.

[0016] 3. This invention takes into account both the collection of dead fish and the collection of uneaten feed and feces. Since the time for collecting dead fish is relatively short, this invention also takes into account the fact that when there is no time for collecting dead fish, the collection of uneaten feed and feces can be carried out normally.

[0017] 4. The device of the present invention can quickly collect dead fish of different sizes by accurately calculating the opening time of the fish passage after the servo reduction motor transmission device rotates, thereby reducing the escape of live fish.

[0018] 5. The device of this invention does not affect the previous construction and pre-buried work of the fish pond. It can adopt a modular component design, which makes installation, operation and maintenance convenient. Attached Figure Description
