Embodiment Construction
[0024] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0025] Such as Figure 1-5 As shown, the ship-borne portable early warning device for sudden changes in water level includes a port ultrasonic sensor 1 arranged on the port side and a starboard ultrasonic sensor 2 arranged on the starboard side. The decoder 4 is connected with the display device 5, and the single-chip microcomputer 3 is also connected with the timer 6 and the buzzer 7 respectively. Connected with the hull, the port side ultrasonic sensor 1 and the starboard side ultrasonic sensor 2 are arranged symmetrically. The early warning instrument is installed on the ship, which can monitor the ship's freeboard height, lateral inclination and water level variability in the water area in real time. When the water level chan...

The invention belongs to the technical field of ships and particularly relates to a shipborne portable water level mutation warning instrument which comprises a larboard ultrasonic sensor arranged on the larboard and a starboard ultrasonic sensor arranged on the larboard. The larboard ultrasonic sensor and the starboard ultrasonic sensor are connected with a single chip microcomputer. The single chip microcomputer is connected with a display device through a decoder and further connected with a timer and a buzzer alarm. The larboard ultrasonic sensor and the starboard ultrasonic sensor are provided with buffer type installation mechanisms and connected with a ship body through the buffer type installation mechanisms. The shipborne portable water level mutation warning instrument has the advantages that the ship freeboard height, the transverse gradient and the water level variability of a water area where the ship is located can be monitored in real time, when the water level changes suddenly, a sailor can adjust the posture of the ship in time according to the data displayed by the warning instrument and a warning sign given by the warning instrument, and accordingly the ship can be protected against risks such as capsizing and stranding.
Description
technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a ship-borne portable early warning instrument for sudden changes in water level. Background technique [0002] With the development of my country's water conservancy and hydropower construction, more and more hydropower stations have been built and put into use. Although the hydropower station can adjust the dry season flow of the river and improve the navigation conditions of ships to a certain extent, the sudden rise or fall of the downstream water level caused by black start, flood discharge or gate closing will affect the navigation, docking and operation of downstream ships. Bring huge potential safety hazards, and may even cause accidents. [0003] There have been some domestic research results on the use of ultrasonic waves to measure river water levels, but most of them are fixed on banks, dams or other places to monitor river water levels. The main purpose is...
