Abstract

The utility model discloses a hydraulic power self-control type flap floodgate. The top of a flap gate (1) is provided with a control water tank (5), the position which corresponds to the top of the gate (1) on the upper end of the control water tank (5) is provided with a water inlet, the gate (1) can be respectively closed or opened when the no water is remained in the control water tank (5) or the water level of the control water tank rises to certain height to swing outward, the control water tank (5) is provided with a water drainage hole used for resetting, and one side of the control water tank is provided with a limiting lug boss (4) used to control the swinging of the gate. with the measures, a principle that an air bag expands during air intake and contracts during the air exhaust can be utilized to control the opening and closing of the gate. The flap floodgate has a simple structure, convenient operation, small investment, and low operating cost.

Description

Waterpower self-control type turnover panel flood gate

Technical field

The utility model relates to a kind of water conservancy projects, is a kind of be used for controlling flood waterpower self-control type turnover panel flood gate of flood discharge such as reservoir, river that is installed in specifically.

Background technology

Dykes and dams have generally all been built in existing reservoir, river, are used for retaining or change to flow to, to drink and field irrigation as people, animal.For the sake of security, the flood control floodgate is installed all generally on dykes and dams, water level surpasses certain altitude as to the water level alarm line time, will open a sluice gate and draw out some water.Present turnover plate type gate medium position has the rotating shaft of horizontal direction, but gate draining when rotating shaft is overturn can recover normal condition when resetting.This gate adopts different control modes, but all is manpower or electric power operation according to the needs that vary in size, not only troublesome poeration, investment is big, operating cost is high, and adopts manual operation also to have certain potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, investment is little, operating cost is low waterpower self-control type turnover panel flood gate.

The waterpower self-control type turnover panel flood gate that the utility model provides, it is that a control water tank is arranged at the top of gate, the corresponding gate top bit in control water tank upper end is equipped with water inlet, the anhydrous or control cistern water level of control water tank rise to certain altitude and outwards swing can make gate be in barrier gate or open a sluice gate two states respectively.

Have the drain hole that is used to reset on the described control water tank.

The positive stop lug boss that the regulating gate swing is arranged at the side of gate.

The utility model because the control water tank is directly to lean on the water of gate top overflow to provide, can be realized the automatic control of gate owing to utilize the opening and closing of the control water tank regulating gate that is installed in the gate top like this.The utility model is simple in structure, investment is little, operating cost is low, security performance is good.

Description of drawings

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the A-A face sectional view of Fig. 1;

Fig. 3 is user mode figure of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the waterpower self-control type turnover panel flood gate that the utility model provides, connect bearing support 2 by rotating shaft 3 respectively in gate 1 left and right sides, make its flexible swinging, one control water tank 5 is arranged at the top of gate 1, corresponding gate 1 top bit in control water tank 5 upper ends is equipped with water inlet 6, the size of control water tank 5 should satisfy that the anhydrous or control cistern water level of control water tank rises to certain altitude and outwards swing can make gate 1 be in barrier gate or open a sluice gate two states respectively.In order to make control water tank 5 can automatically reply original position, on control water tank 5, have the drain hole 7 that is used to reset, the quantity of drain hole 7 and size so that the water of control water tank 5 in can be in the relatively short time with it be discharged to can reset till, and the decrease speed of gate 1 is better when resetting, the impulse force of avoiding descending is excessive, lock produces bigger collision on earth the time, influences safety.At the side of gate 1 positive stop lug boss 4 of regulating gate swing is arranged, be used for limiting the hunting range and the angle of gate 1.

Operating principle of the present utility model is: when reservoir, river level rise to gate 1 top, water will be from gate 1 top overflow, water inlet 6 through control water tank 5 enters then, the water level of control water tank 5 just rises rapidly, when water level reaches certain height, and gravitate, 5 swings of control water tank descend, drive gate 1 along rotating shaft 3 swings, but gate 1 is opened the draining flood discharge, sees Fig. 3.When reservoir, river level descended, the water that enters control water tank 5 was gradually reduced to anhydrous discharge, and the water of 5 li in control water tank is discharged by drain hole 7, and gate 1 drives control water tank 5 pendulum and returns back to original position by moving conversely, sees Fig. 1, realizes drainning off floodwaters automatically retaining.

Claims
