Problems solved by technology
[0003] The existing ship locks only have the function of opening and closing, and cannot detect and prompt the ship's sailing speed. When the ship's sailing speed is fast, it may collide with the gate that has not been fully opened, resulting in damage to the ship lock or the ship, causing unfavorable Necessary loss, so there is an urgent need to design a speed limit reminder device for ship locks

The invention discloses a ship speed limit reminder device for a ship lock, which includes a river channel and a ship body. Grooves are arranged on both sides of the channel, and gates are connected to the two grooves through swinging shafts, and the two gates Cooperating with each other, the two gates are connected with vertical bars through rotating rods, and warning flags are fixedly installed on the two vertical bars, and torsion springs are installed between the two vertical bars and the two gates. Mounting blocks are fixedly installed on the two gates. The advantage is that: when the ship sails fast in the river, the present invention can make use of the change of water flow to automatically make the screw drive the warning flag to swing back and forth, thereby reminding the ship driver to reduce the ship speed in time and avoid the ship from colliding with the ship. The problem of damage caused by the collision of the gate, and the device does not require manual operation, has a high degree of automation, does not need to provide kinetic energy for the rotation of the screw, and has a low cost of use.
Description
technical field [0001] The invention relates to the technical field of ship locks, in particular to a ship speed limit reminder device for ship locks. Background technique [0002] The Beijing-Hangzhou Grand Canal was built in the Spring and Autumn Period. It is the ancient canal with the longest mileage and the largest project in the world, and it is also one of the oldest canals. It is a great project created by the ancient Chinese working people. The Beijing-Hangzhou Grand Canal must have a stepped longitudinal section to form a concentrated water surface drop due to the regulation of flow, canalization and navigation, and due to the constraints of terrain conditions and water surface slope on the canal. The locks allow ships to pass directly through the drop. [0003] The existing ship locks only have the function of opening and closing, and cannot detect and prompt the ship's sailing speed. When the ship sails at a fast speed, it may collide with the gates that are not...
