Problems solved by technology

These management measures reduce the navigation efficiency of ship locks. Although the probability of navigable ships hitting the gate is reduced, the risk of navigable ships hitting the gate cannot be completely avoided.

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0020] figure 1 It is a schematic diagram of the overall structure of the emergency blocking device of the ship lock. A set of lifting mechanisms 17 are arranged at a safe distance from the gate 15 on both sides of the river. Stop protection status. The lifting mechanism 17 performs adaptive lifting through the rack and pinion mechanism as the navigable water level of the lock chamber changes, so as to ensure that the arresting cable or arresting net is at a suitable height. The lifting mechanism 17 includes a rope 11, a buffer device 18, an energy absorbing device 19 and a pulley block 20; one end hanging point of the energy absorbing device 19 and the corresponding blocking mechanism 16 are respectively located on both sides of...

Abstract

According to the technical scheme, a ship lock emergency blocking device comprises two lifting mechanisms which are of the same structure and are symmetrically arranged, the two lifting mechanisms are arranged at the two sides of a lock chamber respectively, and a space used for buffering a ship located in the lock chamber is formed between the two lifting mechanisms and a ship lock gate; a stopping mechanism is hung between the two lifting mechanisms; the blocking mechanism is a blocking net or a blocking cable; the two lifting mechanisms are used for synchronously adjusting the heights of hanging points at the two ends of the blocking mechanism; and the two lifting mechanisms are used for controlling hanging points at the two ends of the blocking mechanism to synchronously move towards the inner side or the outer side of a lock chamber so as to adjust the relaxation state of the blocking mechanism. The ship lock is effectively protected against collision damage.

Description

technical field [0001] The invention belongs to the technical field of emergency blocking of navigable ship locks of river hydropower stations, and in particular relates to an emergency blocking device for ship locks. Background technique [0002] While building dams to intercept river water and store energy, river hydroelectric power stations generally build elevators or navigable locks to ensure that ships can navigate normally. Elevators are mainly suitable for navigation of small-tonnage ships. At present, the main form of navigation for ships on rivers "turning over dams" is navigation locks. In order to prevent the ship from going out of control and hitting the lock, there are mainly management measures such as requiring ships to have two vehicles and two rudders, restricting the speed of ships entering and leaving the lock room and the lock, and delineating the no-stop line. These management measures reduce the navigation efficiency of ship locks. Although the probab...
