Detailed Description

The technical solution of the present invention is further explained by the following examples, but the scope of the present invention is not limited in any way by the examples.

Example 1

A fish ethology observation device is shown in figure 1, and comprises a water pool 1, a water bucket 2, a variable frequency water pump 3, a flow meter 4 and a swimming chamber 5; the bucket is arranged above the water pool, the wall thickness of the bucket is 1cm, the height of the bucket is 1.7 m, and the diameter of the bucket is 50 cm; the length of the pool is 3 meters, the width of the pool is 3 meters, and the height of the pool is 1 meter; the lower end of the bucket is provided with a water pipe which is sequentially connected with a flow meter with the diameter of 15cm and a swimming chamber, the variable frequency water pump is positioned in the water tank, the power is 90KW, a water outlet pipe of the variable frequency water pump is connected with the upper end of the bucket and pumps water into the bucket, the upper end of the bucket is provided with an overflow pipe 6 with the diameter of 10cm and the wall thickness of 0.6cm, the water in the bucket is prevented from being fully expanded, and the opening of the overflow pipe is positioned in the water tank; the swimming chamber is made of an acrylic material and is a cuboid with the specification of 120cm long, 40cm wide and 30cm high, two ends of the swimming chamber are respectively connected with a water inlet pipe and a water outlet pipe through flanges, as shown in figure 2, the diameter of a flange hole 8 on the flange is 300mm, water valves 11 with the diameter of 15cm are arranged on the water inlet pipe and the water outlet pipe, a pair of clamping grooves 7 are arranged on the side wall of the swimming chamber away from two top ends in the swimming chamber and used for inserting a guide plate, the thickness of the guide plate is 8mm, 40cm long and 30cm wide, round holes are uniformly distributed on the guide plate, as shown in figure 3, the water outlet pipe of the swimming chamber is opened in a water pool, the upper top surface of the swimming chamber is a freely-opened cover 9, and closed air vents 10 are arranged at the upper end of the swimming chamber and used for exhausting air in the swimming chamber.
