[0038] Example 2

[0039] Reference Figures 1 to 9 , which is the second embodiment of the present invention, is based on the previous embodiment, and the difference is that when the electric driving unit 200 needs to be repaired, by starting the recovery motor 303, the buckle 301a on one side can drive the insulator 202 to gather and recover the scattered insulators 202.

[0040] Specifically, the suspension unit 100 includes a main cable 101 arranged on the river channel, a horizontal cable 102 is arranged below the main cable 101, a sling 103 is connected between the main cable 101 and the horizontal cable 102, a track 104 is arranged below the horizontal cable 102, and the horizontal cable 102 and the track 104 are connected by a sling ring 104.

[0043] It should be further explained that the main rope 101 is provided as the main suspension load-bearing member; a hole is opened in the middle of the insulator 202 for the recovery rope 301 to pass through; and a hole is opened in the upper part of the electrode 203 for connecting to the cable 204 for power supply, so as to realize the discharge of the electrode 203 to intercept fish.

[0044] Preferably, the electrode 203 is connected to a cable 204 , and the recovery unit 300 includes a recovery rope 301 passing through the insulator 202 , and buckles 301 a are provided on both sides of the recovery rope 301 away from the insulator 202 of the control unit 500 .

[0045] Preferably, a connecting rope 302 is provided between adjacent electrodes 203 , a recovery motor 303 is provided on one side of the recovery rope 301 , and the lifting unit 400 includes a supporting column 401 provided on the bank slope 600 .

[0046] Among them, by arranging buckles 301a on both sides of the insulator 202 farthest from the centralized control side on the recovery rope 301, the volume of the buckle 301a is larger than the size of the opening in the middle of the insulator 202, a connecting rope 302 is arranged between adjacent electrodes 203, the recovery rope 301 is suspended on the lifting frame pulley 402b-1 on both sides, and a recovery motor 303 is arranged on the centralized control side, the recovery rope 301 is driven to rotate by the recovery motor 303, and the buckle 301a drives the insulator 202 farthest from the centralized control side to move left and right, so that all the electrodes 203 can be driven to move left and right in turn, thereby realizing the recovery and deployment of the electrode 203 string for maintenance work.

[0047] Preferably, a steering pulley block 403 is provided on the top of the supporting column 401, and the two ends of the steering pulley block 403 are connected to the lifting frame 402 and the winch 405 through a lifting cable 404. A water level meter 406 is provided on the slope 600 close to the control unit 500, and a door-type frame 401a and a ladder 401a-1 are respectively provided on the supporting column 401.

[0048] The supporting columns 401 are arranged on the bank slopes 600 on both sides, and the lifting frames 402 on both sides are supported on the supporting columns 401. A steering pulley block 403 is arranged on the top of the supporting columns 401. The steering pulley block 403 is composed of a steering pulley 403a and a steering pulley frame 403b. The steering pulley frame 403b is 45 degrees and is installed on the top of the door-shaped frame 401a. The lifting steel cable 404 is connected to the lifting frame 402 and the winch 405 through the two ends of the steering pulley block 403. A water level meter 406 is arranged on 600, and the winch 405 is controlled by the control signal of the water level meter 406, so as to drive the lifting frame 402 to move up and down, and finally the suspension unit 100, the electric chasing unit 200 and the recovery unit 300 attached to the lifting unit 400 are controlled to move up and down, so as to adjust the optimal fish blocking elevation of the electrode 203 under different water levels. In addition, during the flood period, the lifting unit 400 can also be lifted to above the flood level to protect the whole device from being submerged and eroded by the flood.

[0049] By setting up the winch 405, the winch 405 needs to rotate the wire rope horizontally, mainly through the pulley groove cooperating with the connection method of the wire rope, and the lifting frame 402 reciprocates up and down, so the steering pulley group 403 is set to rotate 90°, so that the winch 405 can lift the lifting frame 402.

[0050] It should be mentioned that the pulley frame 403b is at a 45° angle, mainly because the winch 405 needs to make a 90° turn when pulling up, so the pulley frame 403b is set at a 45° angle for best force.

[0051] Preferably, a lifting track 401a-2 is provided on one side of the door-type frame 401a, and the lifting frame 402 is composed of a longitudinal beam 402a and a transverse beam 402b, and a running wheel 402a-1 is provided on the longitudinal beam 402a.

[0052] Preferably, a lifting frame pulley 402b-1 is provided on the cross beam 402b, and a lifting lug 402b-2 is provided on the top of the cross beam 402b, and the lifting frame pulley 402b-1 is movably matched with the lifting track 401a-2.

[0053] The supporting column 401 includes a door-type frame 401a, and ladders 401a-1 are set on both sides of the door-type frame 401a, which can be used for daily maintenance by the staff. A lifting track 401a-2 is set on one side of the door-type frame 401a, and two rows of running wheels 402a-1 are set on the two longitudinal beams 402a. The running wheels 402a-1 are configured to be slotted and can be closely matched with the shape of the lifting track 401a-2. A lifting frame pulley 402b-1 is set on the cross beam 402b, and a lifting frame lifting ear 402b-2 is set on the top cross beam 402b for lifting the lifting frame 402.

[0054] In summary, by setting the lifting unit 400, when encountering flood weather, in order to protect the long-term use of the electric driving unit 200 and prevent it from being damaged by scouring, by using the winch 405, the lifting steel cable 404 can be adjusted to the upper side together with the recovery unit 300 through the lifting lug 402b-2, thereby cleverly avoiding the scouring of the flood, the operation is very simple, and the service life of the overall device is extended.

[0055] Example 3

[0056] Reference Figures 1 to 9 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that this embodiment provides an application method of a fish fence.

[0057] Specifically, by connecting the electrode 203 and the cable 204 to supply power, discharge can be performed to intercept fish, the electric chasing unit 200 can be recovered to one side by controlling the recovery unit 300, and the electric chasing unit 300 can be controlled to move up and down by controlling the lifting unit 400.

[0058] In summary, through this method, the fish barriers can be widely used in various rivers to flexibly respond to weather conditions. When encountering extreme weather, it is convenient for staff to quickly and safely take first aid measures, which is very convenient.
