Background technique

According to the applicant's knowledge, the dam is the main backwater structure in the embankment hydropower station. Existing dams can be divided into two categories: concrete dams and earth-rock dams. The type of dam needs to be selected based on a comprehensive comparison of the natural conditions of the dam site, building materials, construction site, diversion, and cost.

The existing dams have the problems of long construction time, high construction difficulty, and large material and energy consumption during the construction process. Specifically reflected in: 1. When building a dam, a large amount of concrete or earth and stone needs to be used, the material consumption is large, the construction time is several years or decades, and the construction is difficult; 2. Commonly used in dams The gate is made of concrete or steel plate. Generally, when the gate is opened, it is opened by an elevator. Since the water pressure at the gate is relatively high after the dam is completed, the gate must have considerable strength, which inevitably requires the use of a large amount of concrete. and steel, and the elevator must have considerable power to open the gate, which consumes a lot of energy.

Left and right symmetrical reinforcing ribs are arranged on the supporting beam, one end of the reinforcing rib is connected with the middle part of the supporting beam, and the other end is connected with the main support.

There are several gate plates, all of which are connected to the gate frame through rotating shafts, and the rotating shafts of the gate plates are connected through transmission gears.

It also includes a top platform, and the top platform is arranged on the beam support.

A transmission sprocket is also arranged on the rotating shaft of the gate plate at the middle position.

The top platform is provided with a driving device, and the driving device is connected with a transmission sprocket through a chain.

It also includes a transition wheel arranged on the top platform, and the outer side of the chain is connected with the transition wheel.

There are at least two main supports.

A water-retaining dam of the present invention adopts a frame-type steel frame structure, the overall structure is firm and durable, can be assembled on site, installation and construction are convenient, and the construction period is short; a water-retaining dam of the present invention can be used according to different conditions of the dam, The number of main brackets is selected, and the flexibility is high; the water blocking dam of the present invention has a number of rotating door panels on the gate, which is convenient to open and close. Compared with the traditional one, the entire gate panel needs to be raised to save energy.

detailed description

As shown in Figures 1 and 2, a water-retaining dam of the present invention includes a dam body frame, a dam body baffle plate 4 and a gate 5 located on the dam body baffle plate 4; the dam body frame includes a base support 1 , left and right symmetrical main bracket 2 and crossbeam bracket 3, described left and right symmetrical main bracket 2 is arranged on the base bracket 1, there are four main brackets 2 in the figure, usually there are at least two main brackets 2, and the main bracket The number of 2 is determined according to the specific site conditions. The top of described main support 2 is provided with beam support 3; Described main support 2 comprises the sub-support 21 of left and right symmetry that is connected together, and described sub-support 21 inside is provided with vertical support beam 22, and described support beam 22 There are reinforcing ribs 23 on it; the gate includes a gate frame 51 and a number of gate plates 52 which are rotatable inside the gate frame 51; The left and right ends are respectively connected with the left and right symmetrical main brackets 2.

The auxiliary bracket 21 of the present invention is an isosceles triangle bracket. The support beam 22 is provided with bilaterally symmetrical reinforcement ribs 23 , one end of the reinforcement rib 23 is connected to the middle of the support beam 22 , and the other end is connected to the main support 2 .
