Embodiment Construction

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0028] like figure 1 , figure 2 As shown, a suspension fish blocking system according to the present invention includes a cross-sectional structure, a water surface suspension structure, a fish blocking electric grid and an effect observation device;

[0029] The section spanning structure includes a main cable 1, a supporting structure 2, a cable saddle 3 and an anchorage 4. The supporting structure 2 and the cable saddle 3 are respectively arranged at both ends of the fish blocking section, and the cable saddle 3 is arranged on the supporting structure 2 At the top, the anchorage 4 is set in the bedrock at both ends of the fish blocking section, and the main cable 1 is connected to the anchorage 4 through the supporting structure 2 and the cable saddle 3; in practical applications, ...

Abstract

The invention discloses a floated fish blocking system comprising a section across structure, a water surface floating structure, a fish blocking electric grid and an effect observer; the section across structure comprises main cables, support structures, cable saddles and anchors; the main cables are connected with the cable saddles and anchors through support structures; the water surface floating structure comprises floaters arranged on the main cables and used for bearing the fish blocking electric grid, wherein the floaters are fixed on the main cables through fasteners; the fish blocking electric grid comprises vertical cables, transverse cables, counterweights, an electrode array, a pulse power supply and power transmission cables; the top of the vertical cable is connected with the main cable, and the bottom of the vertical cable is connected with the counterweight; the transverse cable is connected with the vertical cable; the electrode array comprises a plurality of electrode tubes arranged on the vertical cables; the power transmission cables are respectively connected with the pulse power supply and the electrode tubes; the effect observer comprises a sonar echometer arranged on the main cable. The floated fish blocking system is not limited by mounting field environment conditions, and can suit for various fish blocking section widths, depths and water level changing requirements.

Description

technical field [0001] The invention belongs to the technical field of fish management, and in particular relates to a suspended fish blocking system. Background technique [0002] In order to meet the needs of human production, life, fish farming, and fish blocking in waters such as rivers, reservoirs, and lakes, fish blocking facilities are generally used in the waters to block, intercept, block, separate, drive, and control fish. To lure fish, to ensure that fish move according to the way or trajectory preset by humans, the existing relatively mature and effective fish blocking facilities include chemical fiber blocking nets, fish blocking fences, fish blocking electric fences, etc. Among them, fish blocking electric fences Fish works best. The fish blocking electric grid is made of metal conductors on the fish blocking section to form an electric array, and the underwater electric field is used to stimulate the fish, so that when the fish swim to a certain distance, the...
