Embodiment 1

[0038] see figure 1 — figure 2 , the present invention includes two processes of descending and rising of the water level gate 1 during application.

[0039] During the descent: at the beginning of the descent, there is no pressure oil in the accumulator 4, and the electromagnet on the two-position three-way electromagnetic reversing valve 3 is energized to conduct the oil circuit between the upper oil inlet 31 and the outlet oil port 33 , and then the hydraulic oil in the cylinder oil chamber 62 flows into the accumulator 4 for storage through the speed regulating valve 11 and the No. 1 check valve 9 successively under the action of gravity, and at the same time, with the outflow of the hydraulic oil, The piston 61 falls naturally under the action of gravity, and drives the water level gate 1 to descend through the push rod 2 .

[0040] During the ascent process: at the beginning of the ascent, the accumulator 4 has already stored the hydraulic oil input during the previou...

Abstract

The invention relates to a water level brake with a function of precisely controlling the lifting height for a river engineering model. The water level brake comprises a water level brake body, a pushrod, a two-position three-way electromagnetic reversing valve, an energy accumulator, a manual variable pump and a hydraulic cylinder. The two-position three-way electromagnetic reversing valve is internally provided with an upper oil inlet, an oil output port and an oil discharging port. The water level brake body is connected with the middle of a piston in the hydraulic cylinder through the push rod, a cylinder oil cavity below the piston communicates with the upper oil inlet, the oil output port communicates with an oil inlet end of a first one-way valve, an oil output end of the first one-way valve communicates with the energy accumulator and an oil inlet end of a second one-way valve, an oil outlet end of the second one-way valve communicates with an oil inlet end of the manual variable pump, and an oil outlet end of the manual variable pump communicates with the oil discharging port. The precision of controlling the lifting height of the water level brake is high, the water level brake is easy to operate, and energy is saved.

Description

technical field [0001] The invention relates to a control design of a water level gate, which belongs to the technical field of river engineering models, in particular to an accurate and controllable water level gate for river engineering models. Background technique [0002] The river engineering model is an important technical means to study the water flow and sediment movement of rivers, rivers and lakes. The precise control of the water level at the outlet of the model is one of the main determinants of whether the model can be similar to the prototype, especially the simulated water level is affected by the tidal current Larger estuary areas. In application, the water level at the outlet of the model can be affected by the lifting and lowering of the water level gate. The more precise the lifting control of the water level gate is, the more accurate the water level control is. However, in the prior art, the water level gate is often controlled by a horizontal flap door ...
