Description

[0002] With the development and construction of city, people's life water increases, usually constructs artificial lake or reservoir etc. for the fresh water storage and use of city, and these city lakes and reservoirs are often communicated with the upstream river and downstream river outside the urban area to form flow in order to keep the flowability of live water and avoid water quality deterioration.

[0003] However, the existing reservoir usually only has a single artificial lake design, that is, directly communicated with the upstream and downstream river. Firstly, the reservoir directly taking river water is easy to cause more silt at the bottom and silt accumulation due to the turbulent river flow carrying a large amount of sand and stone into the reservoir, thereby affecting water quality. Then in the rainy season, the injection of rainwater is easy to form a flood, and the reservoir cannot drain in time, which may cause the water surface to rise or the water flow in the reservoir to speed up, and even impact the gate and retaining wall of the reservoir. Finally, in the dry season, the river flow is less, the reservoir cannot be supplemented with enough water, and the water quantity connected to the downstream river after treatment in the reservoir is less, further limiting the flowability of live water in the reservoir, and the water quality is more likely to deteriorate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-5As shown, this utility model discloses a water diversion and guiding structure for urban lakes and reservoirs, comprising a secondary reservoir 2, a main reservoir 1, and a buffer reservoir 3 arranged along the water flow direction. The secondary reservoir 2 is connected to the upstream of the river. An isolation wall 5 is provided between the secondary reservoir 2 and the main reservoir 1. A connecting device 6 is provided on the isolation wall 5 to ensure that the water level of the main reservoir 1 and the secondary reservoir 2 are kept consistent, and the bottom height of the secondary reservoir 2 is greater than that of the main reservoir 1. A first gate 7 is provided between the main reservoir 1 and the buffer reservoir 3. A water flow regulating component 8 is provided on the first gate 7 to allow the water in the upper layer of the main reservoir 1 to slowly flow into the buffer reservoir 3. The buffer reservoir 3 is connected to the downstream of the river. A storage reservoir 4 is also provided on the side of the main reservoir 1 away from the secondary reservoir 2, and the bottom of the storage reservoir 4 is higher than the water level of the main reservoir 1. This invention enables urban reservoirs to more stably draw water from natural river channels. Water is pumped to secondary reservoir 2 and treated, such as buffering, settling, and water quality testing. Then, using the communicating vessel 6, the clearer upper layer of water is diverted to the main reservoir via the principle of communicating vessels. This ensures that the water levels in the main and secondary reservoirs are as consistent as possible. Most subsequent testing and sampling can be conducted in the smaller secondary reservoir 2, reducing the impact of undercurrents within the reservoir. Meanwhile, the buffer reservoir 3 effectively handles large water volumes during the rainy season. Under normal circumstances, the flow regulation component 8 adjusts the amount of water flowing from the main reservoir 1 into the buffer reservoir 3, controlling the buffer reservoir 3 at a lower water level to prevent rapid currents downstream. Furthermore, in the event of heavy rain or flooding, the flow regulation component 8... If the water flow is insufficient to control the water volume, the first gate 7 can be opened to release the water flow, prioritizing the prevention of the main reservoir 1 from exceeding the warning value. The buffer reservoir 3 is usually at a lower water level, and the excess water flow is slowed and controlled by the buffer reservoir 3, so the downstream of the river will not directly accommodate a large amount of water flow, and the flood peak can be gradually reduced. At the same time, the storage reservoir 4 can also slow down, replenish and store water flow during the dry season. When the water volume is sufficient, some fresh water can be stored in the storage reservoir 4. When the water volume of the main reservoir 1 decreases and is insufficient to reach the height of the water flow regulating component 8 or the water flow regulating component 8 cannot guide enough water into the buffer reservoir 4, the storage reservoir 4 can be opened to replenish the water flow of the main reservoir 1 and restore the water flow of the main reservoir 1, etc., to prevent the formation of stagnant water.

[0024] Specifically, the connecting device 6 includes a sealing pipe 61 spanning the isolation wall 5. The two ends of the sealing pipe 61 extend to the upper part of the secondary reservoir 2 and the lower part of the main reservoir 1, respectively. The sealing pipe 61, located on the top side of the isolation wall 5, is also connected to a first water pump 63 via a pressure valve 62. In use, the pressure valve 62 is opened, and the first water pump 63 draws water into the sealing pipe 61. Once the sealing pipe 61 is full of water, the first water pump 63 and the pressure valve 62 are closed to reduce energy consumption. Since the pressure in the secondary reservoir 2 and the main reservoir 1 is basically the same, according to the principle of communicating vessels, the water will gradually flow downhill through the sealing pipe 61 until the water level in the main reservoir 1 is the same as that in the secondary reservoir 2. Generally, the water level in the secondary reservoir 2 is not lower than the opening of the sealing pipe 61 at its upper part, ensuring that the upper water level of the secondary reservoir 2 flows into the main reservoir 1, while sediment and other sediments tend to settle to the lower part of the secondary reservoir 2 and are cleaned periodically. When the connection is stopped, the air pressure valve 62 is opened again to cut off the water flow in the sealing pipe 61 for a certain period of time. Due to the entry of atmospheric pressure, the water in the sealing pipe 61 is discharged to both sides, which can disconnect the connection between the auxiliary reservoir 2 and the main reservoir 1.

[0025] Meanwhile, to prevent the water level of the secondary reservoir 2 from becoming too high and to cope with sudden flooding in the river channel, the top side of the isolation wall 5, near the secondary reservoir 2, is recessed and equipped with a flow equalization hole 51. The flow equalization hole 51 connects to the other side of the isolation wall 5 and is connected to the main reservoir 1 through a second gate 52. The second gate 52 is positioned higher than the water level of the main reservoir 1. The water level of the secondary reservoir 2 generally does not exceed the flow equalization hole 51. If the water level rises due to various reasons, causing the water in the secondary reservoir 2 to preferentially enter the flow equalization hole 51, it will be diverted to the second gate 52 below. By opening the second gate 52, some of the water flow can be guided into the main reservoir 1. Furthermore, a drainage pipe 53 is installed inside the isolation wall 5, which is connected to each flow equalization hole 51. A water pressure tester 54 is also installed inside the drainage pipe 53. When the water flow suddenly increases too much, the flow equalization hole 51 can be manually drained through the drain pipe 53, and the water flow can be detected by the water pressure tester 54. The opening of the second gate 52 can be controlled by means of signal connection, so as to prevent the failure of manual operation to deal with the emergency in time.

[0026] In one embodiment, the buffer reservoir 3 is lower than the main reservoir 1. The water flow regulating component 8 includes a flow limiting pipe 81 located above the main reservoir 1, and the first gate 7 is a structure capable of reciprocating up and down. The flow limiting pipe 81 allows water from the main reservoir 1 to slowly flow into the buffer reservoir 3. The flow limiting pipe 81 is equipped with regulating valves and flow meters 82, etc., to regulate and detect the water flow, so that the buffer reservoir 3 is maintained at a low water level, but a certain flow rate is guaranteed to maintain the formation of flowing water. When a decrease in flow rate is detected, which is insufficient to form a water flow, the connection of the auxiliary reservoir 2 can be temporarily closed, and the aforementioned reserve reservoir 4 can be activated to replenish the main reservoir 1. When an excessive flow rate or excessive water pressure at the regulating valve is detected, including situations such as a rise in the water level of the main reservoir 1, this can be detected by the water level gauge 83 installed on the first gate 7. In this case, the first gate 7 needs to be opened simultaneously to allow the excess water in the main reservoir 1 to flow into the buffer reservoir 3 first. Since the buffer reservoir 3 is always at a low water level, a large amount of water will not immediately exceed the high water level threshold. Here, it can be further configured that several third gates 9 are arranged at intervals along the water flow direction in the buffer reservoir 3. By opening and closing the third gates 9, the high water level water is gradually flowed into the downstream of the river in batches to mitigate the impact of flooding.

[0027] In addition, a three-way valve 41 is installed at the bottom of the reservoir 4 on the side facing the main reservoir 1. The three-way valve 41 connects the lower and upper layers of the reservoir 4 and a detachable second pump 42. The connection between the reservoir 4 and the main reservoir 1 is as follows: when water is pumped from the main reservoir 1 to the reservoir 4, the second pump 42 is installed, the three-way valve 41 is opened in the upper layer pipe, and the water flows into the reservoir 4; when the reservoir 4 is replenishing water to the main reservoir 1, the second pump 42 is removed, the three-way valve 41 is opened in the lower layer pipe, or both the upper and lower layer pipes are opened simultaneously, allowing the water to flow into the main reservoir 1 by its own gravity.
