Description

A small semi-automatic adjustment gate

technical field

The utility model relates to the technical field of hydraulic engineering, in particular to a small semi-automatic adjustment gate.

Background technique

A water conservancy project is a project built for the purpose of controlling and deploying natural surface water and groundwater to achieve the purpose of eliminating harm and increasing profits. The gate is a control facility used to close and open the drainage channel. It is an important part of hydraulic structures. It can be used to intercept water flow, control water level, adjust flow, and discharge sediment. At present, some gates need to be manually opened and closed, and they cannot drain water independently, wasting manpower and material resources. Although others can be adjusted independently, they are mostly in the mode of one-time adjustment, which cannot be adjusted in multiple levels and is clumsy and fragile. Therefore, in view of the above problems, a small semi-automatic adjustment gate is proposed.

The main formula principle is: P=ρ ₈ H ₁ ; M ₈ l ₁ =Pl ₂

In the formula: P is the water pressure; M is the mass of the gate itself; g is the acceleration of gravity, taking 9.8m/s ² ; l ₁ is the distance from the center of gravity of the gate to the rotating shaft, in m; ρ is the density of normal water, The unit is kg/m ³ ; H ₁ is the height from the water pressure action point on the gate to the surface of the water body, in m; l ₂ is the distance from the water pressure action point to the rotating shaft, in m.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a small semi-automatically adjustable gate, the gate is provided with an adjustment gate, which can automatically drain water when the flow is small, and the gate can be raised to discharge floods by closing the gate when the flow is large, and the sealing performance is high, The safety performance of the gate is guaranteed.

The technical scheme of the present utility model is as follows:

A small semi-automatic adjustment gate, including a square frame, a column is arranged at the lower part of the square frame, a groove is arranged on the inner side of the column, the gate can move up and down in the groove and has good sealing performance, and a screw hoist is arranged on the top of the square frame, and the screw Connect with the gate to realize the up and down movement of the gate. There is a gate on the gate, which can store water well when it needs to store water; when the water head reaches a certain height, the gate can be automatically drained by adjusting the gate bolt. When the flow is large, the two gates are tightly closed and have good sealing performance, and the gate is lifted by the screw hoist to realize flood discharge.

The gate plate is provided with a water stop, and the sealing performance is good when closed.

The utility model is provided with a sluice plate on the sluice gate, and the multi-level automatic adjustment of drainage under different flow rates can be realized through the adjustment and transformation of the sluice bolt, without lifting the whole sluice gate, saving a lot of manpower and material resources.

Detailed ways

Referring to the accompanying drawings, a small semi-automatic adjustment gate includes a bottom plate 8, a symmetrical column 6 on the bottom plate 8, a liftable gate 10 is provided on the column 6, and the gate 10 is connected by a screw 3 and a screw hoist 2 to realize up and down. Move, the side wall of the column 6 is provided with a groove, the gate 10 moves up and down in the groove, the gate 10 is provided with a gate 9 for automatic drainage, and the gate 9 is provided with a sealing strip 11 , the shutter bolt 5 is inserted in the card slot 7 to control the closing of the shutter 9 .

Condition 1: When a large amount of water is stored, place the "earth"-shaped gate bolts in the middle and lower grooves and lower the gate for large-scale water storage;

Condition 2: When carrying out small-scale water storage, put the "earth"-shaped gate bolt upside down to form a "dry" shape and place it in the middle and lower grooves, so that the upper gate can automatically discharge water under the action of water pressure, and the The water volume is controlled at a certain height;

Condition 3: When small-scale water discharge is carried out, the gate bolt can be placed in the upper middle and upper grooves, and the lower gate can be discharged;

Condition 4: When the medium-scale water discharge is carried out, the gate bolt can be placed in the idle slot on one side, and the two gates are fully opened for water discharge;

Condition 5: When the inflow is too large and it is easy to cause harm, the gate can be lifted by the screw hoist to discharge water on a large scale.
