Description

Anti-freezing device for flap gate

Technical Field

The utility model relates to a flap gate anti-freezing device belongs to flap gate technical field, can use at municipal trades such as water conservancy water and electricity trade and river course view.

Background

Flap gate: a gate type capable of automatically controlling a water level. The flap gate has the characteristics of investment saving, convenient management and the like, and is applied to more and more hydraulic and hydroelectric engineering. The working principle of the flap gate is that the lever is balanced and rotated, namely the water power and the weight of the gate are mutually balanced, and the aim of controlling the water level is achieved by additionally arranging a damping feedback system. In cold areas, when the shutter gate operates in winter, the problem of water freezing is obvious, and the shutter gate cannot bear ice pressure, so that the normal operation of the shutter gate is influenced. At present, no anti-freezing measure specially aiming at the flap gate exists.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the anti-freezing device of the flap gate is simple in structure, improves the anti-freezing capacity of a water area, and guarantees the normal operation of the flap gate.

For solving the technical problem the utility model discloses the technical scheme who adopts is: the flap gate anti-freezing device comprises a flap gate arranged in a water conservancy facility, wherein a gas pipe is arranged in the front water area of the flap gate, the gas pipe is fixedly connected with a floater, the gas pipe is arranged on the water surface through the floater, the gas inlet end of the gas pipe is connected with a compressed air pump, the gas pipe is provided with exhaust holes at intervals along the length direction of the gas pipe, and the gas outlet direction of the exhaust holes points to the water body in the front water area of the flap gate.

Further, the method comprises the following steps: the axis of the gas pipe is parallel to the rotation axis of the flap gate.

Further, the method comprises the following steps: the floats are arranged at intervals along the length direction of the air conveying pipe.

Further, the method comprises the following steps: exhaust holes are uniformly arranged on both sides of the gas pipe.

Further, the method comprises the following steps: each exhaust hole is provided with a check valve, so that the exhaust holes can only exhaust towards the outside.

Further, the method comprises the following steps: the flap gate is arranged with a plurality of channels along a straight line, and the same gas pipe is arranged in the water area in front of the plurality of flap gates.

The utility model has the advantages that: the air pipe is arranged in the water area in front of the flap gate, and the compressed air is used for disturbing the water surface so as to prevent the water surface in the water area in a certain area from being frozen. Because the gas pipe sets up on the cursory, the cursory can be along with water level variation automatically regulated, adapts to different water level condition, and accommodation is wide. Compressed air is blown in by adopting a mode that a plurality of exhaust holes are distributed on a gas pipe, a single compressed air pump can cover a larger range, the structure is simple, the investment is saved, the worry and the labor are saved, and a large amount of fund maintenance is not needed.

Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

As shown in fig. 1 to fig. 3, the utility model discloses a set up flap gate 3 in hydraulic equipment, flap gate 3's the place ahead waters has arranged gas-supply pipe 1, gas-supply pipe 1 and cursory 2 fixed connection, and gas-supply pipe 1 sets up on the surface of water through cursory 2, and gas-supply pipe 1's inlet end is connected with compressed air pump, and gas-supply pipe 1 has exhaust hole 4 along its length direction interval arrangement, and exhaust hole 4's the directional water in flap gate 3 the place ahead waters of the direction of giving vent to anger. Wherein, the compressed air pump is used for providing compressed air, and the capacity of the compressed air pump can be determined by calculation according to the width of the flap gate 3; the gas pipe 1 is a pipeline for transmitting compressed air, the gas pipe 1 is provided with an exhaust hole 4, and the air speed of the exhaust hole 4 is ensured to disturb the water surface area in a certain area so as to prevent the water surface from freezing; the air outlet direction of the air outlet holes 4 is pointed to the water body so as to play a role in disturbing the water body; the buoy 2 is used for fixing the gas pipe 1 and enabling the gas pipe 1 to always float on the surface of a water body.

In order to better play a role of disturbance and enable the gas pipe to cover a larger effective working range, the axis of the gas pipe 1 is parallel to the rotation axis of the flap gate 3. Exhaust holes 4 are uniformly arranged on both sides of the gas pipe 1. For the mode in unilateral cloth hole, the utility model provides a two side cloth hole modes have better disturbance effect.

Each of the exhaust holes 4 is provided with a check valve so that the exhaust hole 4 can exhaust only toward the outside. Because the check valve is arranged, water on the outer side cannot enter the air delivery pipe 1 through the check valve, the arrangement position of the exhaust hole 4 can be slightly lower than the water level line 5, even if a small amount of water flows back into the outer end of the exhaust hole 4, when high-pressure compressed air is introduced into the air delivery pipe 1, after the check valve is opened, the water can be sprayed out under the action of the compressed air.

In order to fix the gas pipe 1 conveniently, the floats 2 are arranged at intervals along the length direction of the gas pipe 1.

When implementing, the shutter gate 3 has generally arranged the multichannel along the straight line, the utility model discloses same root gas-supply pipe 1 has been arranged in the waters in multichannel 3 the place ahead of shutter gate, can simplify the device structure, sparingly invests in.
