Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with the accompanying drawings. The equipment is very clear to those skilled in the art.

[0016] See figure 1 , The principle of the system of the present invention is: the first hydraulic winch and the second hydraulic winch are respectively provided on both banks of the river, and the steel wire rope (a) 9 on the first hydraulic winch (a) 1 is on the hydraulic winch (a) 1 Connect the fixed pulley (a) 3 vertically upward, connect the fixed pulley (b) 4 horizontally to the right, and connect the fixed pulley (c) 5 vertically downward, and then connect the upper end of the blocking net to the right horizontally. Second, the steel wire rope (b) 10 on the hydraulic winch (b) 2 starts from the drum on the hydraulic winch (b) 2 and connects the fixed pulley (d) 6 vertically upwards, and connects the fixed pulley (e) 7 horizontally to the right. The fixed pulley (f) 8 is vertically connected downward, and the...

Abstract

The invention relates to the field of water conservancy and shipping engineering and specifically relates to an overwater ship-stopping device. The overwater ship-stopping device is characterized by comprising a constant tension system and a lifting system, wherein the constant tension system comprises a hydraulic winch, fixed pulleys and a device box; the lifting system comprises a speed reducer, a chain wheel, a chain and a device box; started from a roller on the hydraulic winch, a steel wire rope is upward vertically connected with the fixed pulley (a), is horizontally connected with the fixed pulley (b) toward the right side, is downward vertically connected with the fixed pulley (c), and then is horizontally connected with one end of the upper part of a stopping net toward the right side; the device box is arranged between the fixed pulley (c) and the fixed pulley (f); two vertical chain devices are arranged inside the fixed pulley (c) and the fixed pulley (f); a normally closed brake is connected with the top of the chain; and river ways on left and right two sides are symmetrically arranged. Compared with the prior art, the overwater ship-stopping device has the advantages that a ship can be efficiently prevented from being damaged under the condition of ensuring effective stopping, the vertical lifting of the stopping net is realized by the lifting system, the sea traffic is quickly stopped or recovered, and the operation is flexible.

Description

[Technical Field] [0001] The invention relates to the field of water conservancy and shipping engineering, in particular to a water-holding facility. [Background technique] [0002] Water arresting facilities are generally used in navigable waters of water conservancy and shipping projects such as ship locks and sluices. Their function is to prevent passing ships from hitting the working gates out of control due to violations or misoperations, causing serious accidents. For important large ship locks and sluices, in addition to considering the impact force of the ship, an anti-collision device should be installed in front of the gate to stop the ship within a limited distance to prevent the ship from hitting the gate. [0003] At present, the traditional arresting facilities generally include facilities such as warning signs and anti-collision piles. The warning signs can only serve as a warning and cannot achieve actual arresting effects; the anti-collision pile can play a certai...
