Description

A floating sluice structure based on landscape river

technical field

The utility model relates to the technical field of sluices, in particular to a floating sluice structure based on a landscape river.

Background technique

In the existing gate device, the screw drive is often used to adjust the height of the gate plate to adjust the flow rate. Since the weight of the gate plate is often large, the weight is likely to cause pressure damage to the screw drive device, especially in the case of impact. Moreover, the continuous expansion of the scale of projects such as dams, hydropower stations and ship locks has led to the rapid development of the gate size, head, load and gate opener. At present, there are more than 40 types of hydraulic gates, valves and ship locks classified by gate type, and there are about 10 types of gates that are most widely used. Among them, the flat steel gate and the curved steel gate are widely used. According to the different supporting types and the position of the gate in the water, it can be divided into the down-the-hole flat fixed wheel steel gate; the down-the-hole flat sliding steel gate and the submerged-hole curved steel gate; Surface hole plane fixed wheel steel gate; surface hole plane sliding steel gate, surface hole arc steel gate. Among high-pressure gates, eccentric hinged arc gates and crawler-type flat gates have obvious advantages. Among the lock gates, the "person" gate is the most common application. Among the high-pressure valves of hydropower stations, butterfly valves are the most common, followed by spherical valves. The higher the design head of the gate, the more acute the hydraulic problem of high-speed water flow; the larger the orifice area, the more complicated the structural design and processing problems of the metal structure; Machine requirements are higher. The current development trend of gates is based on simplicity and energy saving, and the types are mainly simple and practical. For gates in plain reservoirs and landscape rivers, they are mainly based on convenient opening and closing, energy saving and high efficiency, and simple structure and operation. At the same time, after the emergence of new gates such as hydraulic automatic flap gates, the development of gates that are simple, efficient, and easy to control and manage has been further promoted.

Detailed ways

The present utility model will be further described in detail below through specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present utility model.

As shown in FIGS. 1 to 4 , a floating sluice structure based on a landscape river channel includes a pier 1 , a sluice body 2 , a sluice motion damping device, a sluice body conveying and drainage device 3 and a pulley device 4 .

There are two gate piers 1, and the two are arranged opposite to each other. The slopes of the two gate piers 1 face the same side, and the gate pier 1 adopts a cast-in-place reinforced concrete structure. Each gate pier 1 is respectively provided with a sluice motion damping device, and the sluice motion damping device comprises a baffle 6 and a damping connection structure 5 arranged oppositely, and each damping connection structure 5 is respectively installed on the inclined surface of the corresponding gate pier 1, The shock-absorbing connection structure is arranged obliquely downward along the oblique side of the slope of the gate pier 1 . The baffle 6 is made of reinforced concrete, and the two ends of the baffle 6 are respectively connected with the top of the shock-absorbing connection structure 5 erected on the gate piers 1 on both sides. The baffle 6 protrudes from the top of the gate pier 1, and the baffle 6 is parallel to the water surface. to connect the shock absorber. The baffle 6 is used to provide a platform for installing the shock absorber. When the flow rate of the incoming water is large, that is, the kinetic energy of the water is large, it can play a certain stabilizing role, that is, prevent the sluice body 2 from deviating from the track from the upper part of the gate pier 1 . The shock-absorbing connecting structure 5 and the baffle 6 together form a mutually supported and stable moving structure. The shock-absorbing connecting structure of the present invention can adopt a spring mechanism or a hoist device with a high elastic coefficient. The connection between the hoist and the baffle 6 or with the sluice body 2 can use the existing hydraulic telescopic hoist, which can be connected to a certain power equipment (such as a motor). Usually, a spring device with a higher elastic coefficient is used. That's it.

The pulley device 4 includes a chute and a pulley, the chute is opened on the inclined surface of the gate pier 1, and the chute is located on the lower side of the shock-absorbing connecting structure 5, and the pulley is slidably arranged in the chute. The sluice body 2 adopts a steel plate structure, and the sluice body 2 is a hollow triangular prism structure. The side surface connecting the sluice body 2 with the pulley is parallel to the inclined surface of the gate pier 1, and the connection between the sluice body 2 and the pulley is provided with a rolling groove, and the pulley is arranged in the rolling groove.

The sluice body conveying and draining device 3 is installed on the upper side of the sluice body 2. The upper side of the sluice body 2 is parallel to the water surface. If it is inclined upstream, it is not conducive to the stability of the sluice body 2. The overall center of gravity of the sluice is inclined to the upstream, which will produce a bending moment inclined to the upstream; if it is inclined to the downstream, it is not conducive to the use of the buoyancy of the upstream water, and it is not conducive to the normal opening and closing of the sluice body 2. The sluice body conveying and draining device 3 includes a water pipe, one side of the water pipe extends into the sluice body 2, the other side of the water pipe extends out of the sluice body 2, and the length of the water pipe extending out of the sluice body 2 is 15-20 cm.

The sluice body 2 is mainly controlled by its own gravity and the impact force of the incoming water and the binding force of the pier 1 (transmitted by the pulley) to control the lifting of the sluice body 2, so as to achieve the purpose of blocking water and passing the water. When the speed or flow of water is small, the buoyancy of water is very small, and the sluice body 2 is in a closed state under the action of its own weight. If water is needed downstream and the gate cannot be opened automatically, control it with the help of a hoist. When the water level rises and the flow increases, the sluice gate converts the kinetic energy of the kinetic water into pressure energy, which increases the buoyancy of the sluice body 2, and the sluice body 2 can be opened by means of buoyancy. The upstream water level further rises, the buoyancy of the water is greater than the self-weight of the sluice body 2, the gate rises along the track, and the gate is opened to a certain degree. At this time, the weight of the sluice body 2 can be changed artificially through the sluice body conveying and draining device 3, which can speed up or slow down the rate and duration of the gate descending. If the flow and flow velocity continue to increase and reach the design maximum water level, the gate opening will reach the maximum. The movement damping device on the upper part of the gate pier 1 can reduce the impact force on the gate. When the speed or flow decreases after the upstream water is discharged to the downstream, the water buoyancy of the gate gradually decreases. When the buoyancy action is less than the self-weight action of the sluice body 2, the gate descends, the water passing area decreases, and the discharge flow decreases. Similarly, at this time, the weight of the sluice body 2 can be artificially changed through the sluice body conveying and draining device 3, which can speed up or slow down the rate and duration of the gate descending. When the upstream water level, water flow, and flow rate decrease to a certain value, the water pressure acting on the lower part of the gate by the upstream water continues to decrease, and the gate will return to the closed state.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. These improvements and Retouching should also be regarded as the protection scope of the present invention.
