Description

Technical Field

[0001] The utility model relates to the field of water conservancy and hydropower engineering, in particular to a floating water intake device used for the water inlet of a reservoir power station. Background Art

[0002] For some reservoir power stations with large water level fluctuations, when the water level changes, since the water intake level needs to be adjusted by lifting the gate, there are often situations where the water intake volume is unstable and the work of adjusting the water intake volume is relatively complicated, and it is impossible to achieve stable and adaptive water intake. Content of the Utility Model

[0003] The utility model aims to provide an over-current floating box as a water passing mechanism, which uses the "concave" structure designed by the over-current floating box itself to pass water, and can keep the water depth of the over-current floating box constant in the floating state under the condition of water level change, so as to stably carry out over-current water intake.

[0004] To achieve the above technical effects, the utility model provides the following technical solutions:

[0005] The utility model provides a floating water intake device, which includes an over-current floating box, a telescopic water isolation device, an over-current device sliding groove and a counterweight;

[0006] The over-current floating box is concave-shaped. Through weight control, the highest point of the concave-shaped box body is configured to be higher than the water surface, the concave point of the concave-shaped box body is below the water surface, and the concave part of the over-current floating box is the over-current port.

[0007] The telescopic water isolation device is connected to the downstream side of the over-current floating box. The telescopic water isolation device includes a telescopic grille assembly and a grille waterproof cloth, and the counterweight is connected below the telescopic water isolation device.

[0008] The over-current floating box drives the telescopic water isolation device to expand and contract in the over-current device sliding groove along with the rise and fall of the water level;

[0009] In this way, no matter how the water level of the upstream of the reservoir changes, the telescopic water isolation device under the floating box automatically adapts to the water level change along with the floating box and expands and contracts in the over-current device sliding groove, so as to cut off the water body below the floating box and keep the surface water flowing stably through the concave part of the concave-shaped floating box.

[0010] Preferably, a weight adjustment device is arranged on the over-current floating box, and by adding or reducing counterweights on the over-current floating box, the total weight of the over-current floating box is adjusted, so as to adjust the water flow volume.

[0011] Preferably, the over-current floating box is provided with a water pump, a solenoid valve, a water filling and draining port and an air inlet and outlet, and the water flow volume is adjusted by filling and draining water into the over-current floating box.

[0012] Preferably, in the floating water intake device, the adjacent gratings in the telescopic grating assembly are connected end to end through a rotating shaft, and the grating waterproof cloth is covered on the upstream surface of the telescopic grating assembly.

[0013] Preferably, a roller is provided at the end of the rotating shaft extending outside the grating.

[0014] Preferably, a rotation limiting device is provided on the telescopic grating assembly, and the maximum expansion angle of adjacent gratings is not greater than 170 degrees.

[0015] Preferably, the flow-through device sliding groove includes a box body sliding groove and / or a telescopic grating sliding groove.

[0016] Preferably, a water isolation component is provided between the telescopic water isolation device and the telescopic grating sliding groove, and a water isolation component is also provided between the concave surface of the flow-through box body and the box body sliding groove.

[0017] Preferably, the floating water intake device further includes a concave-shaped building structure, the box body sliding groove and / or the telescopic grating sliding groove are arranged on both sides of the groove of the concave-shaped building structure, and the counterweight is placed on the groove of the concave-shaped building structure.

[0018] According to the description of the above technical solutions, the floating water intake device of the present invention has the following beneficial effects:

[0019] First, since the telescopic water isolation device of the present invention can use the flow-through floating box as a driving device, the resultant force of the gravity and buoyancy of the telescopic water isolation device and the flow-through floating box is constant, so as to achieve a constant flow-through depth of the surface water from the depression of the flow-through floating box. At the same time, since the present invention uses the flow-through floating box as a driving device, during the water intake process, when the upstream water level rises or falls, the water intake volume will not change. The present invention adopts a counterweight block to keep the telescopic water isolation device at the lower part of the flow-through floating box always in a state of isolating the lower water body.

[0020] Second, the present invention uses a flexible waterproof cloth to cover the grating to form a water isolation component, which is convenient for adaptive telescoping. The overall structure has the characteristics of convenient operation and simple structure.

[0021] Third, the present invention can set the flow-through device sliding groove as a single-support structure with an open upstream side, reduce the jamming during the operation of the flow-through device, facilitate the removal and maintenance of the flow-through device, and improve the stability of the equipment operation and the convenience of maintenance.

[0022] Fourth, the telescopic water isolation component of the present invention has an adaptive elastic mechanism in the width direction of the grating assembly, can adapt to the construction error within a certain range in the width direction of the flow-through device sliding groove, and ensure the water isolation effect of the telescopic water isolation device.

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0036] It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

[0037] In this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0038] As Figure 1 shown, in a floating water intake device of the present invention, it is arranged on the concave-shaped civil engineering structure 1, and the space formed by the concave-shaped civil engineering structure constitutes a flow-through cross-section, and the floating water intake device of the present invention is arranged in the space of this flow-through cross-section.

[0039] As Figure 1 shown in [reference], in the flow-through device sliding groove 2 of the concave-shaped building structure 1, from top to bottom are: the flow-through floating box 3, the telescopic water isolation device 4 and the counterweight 5. The flow-through device sliding groove 2 is arranged on the two inner sides of the concave-shaped civil engineering structure 1. In this embodiment, the box body sliding groove 21 and the telescopic grille sliding groove 22 are through sliding grooves with the same width.

[0040] In this state, the counterweight 5, the telescopic water isolation device 4 and the part of the flow-through floating box 3 below the concave surface together block the flow-through cross-section of the concave-shaped civil engineering structure below the concave surface of the flow-through floating box 3, and only allow the surface water to flow through the top surface above the concave surface of the flow-through floating box 3.

[0041] Since the flow-through floating box 3 is designed as a concave structure with a certain weight and shape, when flowing through the depression at the top of the floating box, the protruding part at the top of the floating box still exposes above the water surface. The flow-through floating box 3 is in a stable floating state as a whole, and even when the water level changes, the floating box slides up and down as a whole, but the flow-through depth at the depression of the flow-through floating box 3 remains stable.

[0042] As Figure 2 shown, an air inlet / outlet hole 34 and a counterweight device 35 are provided on the upper part of the water passing floating box 3.

[0043] As Figure 3 shown, an inlet / drain hole 33, a water pump 31 and a solenoid valve 32 are provided at the lower part of the water passing floating box 3. The water passing depth of the water passing floating box can be adjusted by increasing or decreasing the counterweight or the water volume in the water passing floating box 3, so as to adjust the water passing volume.

[0044] As Figure 4 shown, the length of the water passing floating box 3 in the thickness direction can be greater than the thickness of the box chute 2 to ensure that there is enough buoyancy to keep the whole water passing floating box 3 in a floating state. The length of the counterweight 5 in the thickness direction can be greater than the length of the water passing floating box 3 in the thickness direction, so that the counterweight can be directly lifted to lift the whole floating water intake device out.

[0045] As Figure 5 shown, between two grilles 412 connected up and down of the telescopic grille assembly 41, they are connected by a rotating shaft 411. In this embodiment, the rotating shaft is a whole shaft with a full length. The rollers 413 are arranged at both ends of the rotating shaft 411 extending out of the grille 412. The grille waterproof cloth is covered on the upstream surface of the telescopic grille assembly 41.

[0046] As Figure 6 shown, the telescopic water isolation assembly 43 is installed on the side frame of the grille 412. The telescopic water isolation assembly 43 is composed of a water isolation rubber strip 31 (a U-shaped water isolation rubber strip in this embodiment), a water isolation support plate 432, a water isolation support rod 433 and a water isolation spring 434. In this embodiment, two water isolation support rods 433 are provided. One end of the water isolation support rod 433 passes through the grille 412, so that one side of the U-shaped water isolation rubber strip is fixed on the side frame of the grille 412, and the other end passes through the water isolation rubber strip 31 and is located in the hollow area of the U-shaped water isolation rubber strip. The water isolation spring 434 is also located in the hollow area of the U-shaped water isolation rubber strip, and the water isolation spring 434 is sleeved on the water isolation support rod 433. The water isolation support plate 432 is located in the hollow area of the U-shaped water isolation rubber strip, and the water isolation support plate 432 abuts against the water isolation support rod 433 and the water isolation spring 434. Through this kind of structural design, the other side of the U-shaped water isolation rubber strip abuts against the telescopic grille chute under the support of the water isolation support plate 432, the water isolation support rod 433 and the water isolation spring 434 to maintain the water isolation effect.
