Spur dike type fishway inlet

A spur dike type fishway inlet comprising:

• an upstream flow block wall;
• an extra water supply nozzle;
• and
• an artificial reef,
• wherein the upstream flow block wall is arranged upstream of the fishway inlet,
• wherein a starting end of the upstream flow block wall is connected with an upstream side wall of the fishway inlet through a connecting shaft and a hydraulic strut,
• wherein the extra water supply nozzle is installed in the fishway inlet,
• wherein the artificial reef is set up within a sheltered area of the upstream flow block wall,
• wherein the upstream flow block wall is a floating bulkhead gate, the floating bulkhead gate comprising:
• a floating bulkhead body;
• a set of filling and draining devices;
• and
• a set of fish attracting devices,
• wherein the filling and draining devices are installed in the floating bulkhead body,
• wherein the connecting shaft is coupled to one end of the floating bulkhead body, and a fixing foot is coupled to a bottom of an other end of the floating bulkhead body,
• wherein an outlet of the extra water supply nozzle faces the fishway inlet, and
• wherein the artificial reef is arranged near the fishway inlet and downstream of the flow block wall, which is conducive to a formation of near-natural water flow to attract fish into the fishway inlet, and for fish to rest.
