Abstract

The utility model discloses a simple and convenient elevating gear for small -size river course gate, including cistern and flotation pontoon, wherein the flotation pontoon setting is in the cistern, and the flotation pontoon passes through the rope to be connected with the gate, and the rope is around establishing on the pulley. The upper end of flotation pontoon is equipped with the water inlet, and the lower extreme of flotation pontoon is equipped with the outlet. The upper portion of cistern is equipped with the water delivery mouth, and the lower part of cistern is equipped with the discharge outlet. Beneficial effect: thereby reach the effect that the regulating gate goes up and down through holding quantity of water regulation buoyancy size in flotation pontoon dead weight and the cistern through the pulley transmission. The device is simple and convenient effective, with low costs, longe -lived, easy control. Be convenient for close the floodgate retaining to local water is required, also can switch off the desilting in order to guarantee water environment, safe high efficiency.

Description

A Simple Lifting Device for Small River Gates

technical field

The utility model relates to a lifting device, in particular to a simple lifting device for small river gates.

Background technique

At present, most of the gates are used for large rivers, but the gates for small rivers are not simple enough, the cost and maintenance are high, and the economy and practicability are not strong. And because the gate is fixed around, it is not easy to dredge the river. For smaller rivers, gates are usually not set up because there is no benefit, but for small rivers, whether it is closed for water storage, or opened for flood discharge, irrigation. It is undoubtedly much more convenient to have a gate, and it can also play a positive role in local water needs.

Contents of the invention

The purpose of the utility model is to provide a simple lifting device for a small river gate in order to solve the problem that the existing small river channel does not have a gate or the gate is not simple enough.

The utility model provides a simple lifting device for a small river gate, including a water storage tank and a buoy, wherein the buoy is arranged in the water storage tank, and the buoy is connected with the gate through a rope, and the rope is wound on a pulley.

The upper end of the buoy is provided with a water inlet, and the lower end of the buoy is provided with a discharge port.

The upper part of the water storage tank is provided with a water delivery port, and the lower part of the water storage tank is provided with a water discharge port.

The setting principle of the utility model:

When there is no water in the reservoir, the gate is lifted due to the weight of the buoy with the same mass, which has the effect of opening the gate, and as the water is slowly filled into the reservoir, the buoy rises due to the buoyancy of the water. Through the transmission of the pulley, the gate is slowly lowered to play the role of closing the gate, and water can also be poured into the buoy to better control the lift of the gate through the adjustment of the water volume.

The beneficial effects of the utility model:

The buoyancy is adjusted by the weight of the buoy and the water storage in the reservoir, so that the effect of controlling the lift of the gate is achieved through the transmission of the pulley. The device is simple and effective, low in cost, long in life and easy to control. It is convenient to close the gate and store water for local water needs, and it can also be opened for dredging to ensure the water environment, which is safe and efficient.

detailed description

Please refer to Figure 1:

The simple and convenient lifting device for small river gates provided by the utility model includes a reservoir 1 and a buoy 2, wherein the buoy 2 is arranged in the reservoir 1, the buoy 2 is connected with the gate 4 through a rope 3, and the rope 3 is wound around on pulley 5.

The upper end of the buoy 2 is provided with a water inlet 6 , and the lower end of the buoy 2 is provided with a discharge port 7 .

The upper part of the reservoir 1 is provided with a water delivery port 8 , and the lower part of the reservoir 1 is provided with a water outlet 9 .

The setting principle of the utility model:

When the reservoir 1 is not storing water, the gate 4 is lifted due to the weight of the buoy 2 with the same mass, which has the effect of opening the gate. The buoyancy effect of the buoy rises, and through the transmission of the pulley 5, the gate 4 is slowly lowered to play the role of closing the gate, and water can also be poured into the buoy 2 to better control the lift of the gate 4 through the adjustment of the water volume.
