Device and method for adjusting water level through water resistance

Abstract

The invention relates to a device and method for adjusting the water level through water resistance, and the device comprises an electrode cabin, a compression cabin and a control box cabin which are arranged up and down, the electrode cabin is internally provided with an electrode and an electrode cabin liquid level meter, and the electrode cabin is connected with an electrode cabin water supplementing pipe and an overflow pipe; a compression cabin liquid level meter, a pressure sensor used for measuring the pressure of compressed air on the top of the compression cabin, a compression cabin high-position alarm and a compression cabin low-position alarm are arranged in the compression cabin, a water injection / discharge pipe and a compression cabin air injection / discharge pipe are connected to the compression cabin, and a communicating pipe is arranged between the electrode cabin and the compression cabin. A needle valve for finely adjusting the water level in the electrode cabin is mounted on the air injection / discharge pipe of the compression cabin. The water level of the electrode cabin is adjusted through air pressure, the water level of the electrode cabin can be increased and decreased only by injecting and discharging compressed air, the electrode does not need to be moved, the device has the advantages of being simple and reasonable in structure and easy to operate, the water level is adjusted accurately, the service life is long, the maintenance cost is low, and remote intelligent control can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ship testing, and in particular relates to a device and method for adjusting water level by a water resistor. Background technique [0002] In the mooring test of the ship generator, it is necessary to do the load test with water resistance, and adjust the test power by adjusting the contact between the electrode plate and the water level. Usually, the test power is 0%, 25%, 33%, 50%, 6 loads of 66%, 75%, 100%, and 110%. [0003] The method currently used is that the water level of the water resistance box remains unchanged, and the electrode plate moves up and down to adjust the power of the test. There are currently two ways to move the electrode plate up and down: one is to use the motor to drive the screw to drive the electrode plate to move up and down. In this method, the motor is above the water resistance, and the water vapor will corrode the motor and the screw, which is easy to damage; the othe...

AI Technical Summary

Problems solved by technology

Whether it is a screw type or a pulley type, mechanical movement is required, and an external power supply is required, which is bound to have certain safety hazards

At the same time, the moving parts are all above the water resistance. During the operation of the water resistance, the temperature of the water is very high and contains chemical substances. The water vapor generated is easy to corrode the mechanical moving parts, and the damage is very serious. Frequent maintenance is required, which greatly Increased maintenance costs, frequent maintenance not only affects the normal use of equipment, but also increases the cost

Today, when intelligence is more and more helpful to life and work, it is difficult for this kind of device to realize intelligent control
