Description

Technical Field

[0001] The utility model relates to the technical field of water diversion and regulation projects, in particular to a water intake tower structure based on combined gate and valve scheduling. Background Art

[0002] The water intake tower is located at the front end of the water conveyance line and is an important water intake structure for large-scale water diversion and regulation projects. When using open channels, tunnels or pipelines for gravity water conveyance, it is often necessary to set up a water intake tower at the head of the water conveyance line to control the water flow.

[0003] The applicant has found that there are at least the following technical problems in the prior art: Traditional water intake towers use gates to control water flow and water volume. This control method has a simple structure, is easy to operate, and has strong reliability. However, traditional water intake towers also have some disadvantages. One is that they cannot accurately control the flow. The other is that in water diversion and regulation projects with a large water intake flow range and a large water intake water level variation range, in some working conditions, water cannot be taken as needed and there are potential safety hazards. For example, when the water intake water level is high and the flow is small, the gate opening is small and difficult to control. When the gate opening is small, the water flow conditions through the gate are poor, and it is easy to vibrate and produce a howling sound, endangering the safety of the project. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water intake tower structure based on combined gate and valve scheduling to solve the technical problems existing in the prior art, such as the inability to accurately control the flow, the difficulty in controlling the gate opening when the opening is small, the poor water flow conditions through the gate, vibration, and endangerment to the safety of the project. The many technical effects that can be produced by the preferred technical solutions provided by the utility model are described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water intake tower structure based on combined gate and valve scheduling includes a tower main body, a trash rack, a first concrete breast wall, a working gate, and a flow regulating valve. The trash rack and the first concrete breast wall are both connected to the tower main body, and the trash rack is located in front of the first concrete breast wall. The tower main body is provided with a cleaning guide groove in front of the trash rack. The tower main body forms a separated first water flow channel and a second water flow channel behind the first concrete breast wall. The working gate is arranged at the first water flow channel, and the flow regulating valve is arranged at the second water flow channel.

[0007] Preferably, it further includes a second concrete breast wall. The second concrete breast wall is connected to the tower main body, and the working gate is connected to the second concrete breast wall.

[0008] Preferably, it further includes a first emergency gate, which is connected to the second concrete breast wall and arranged at the first water flow channel, and the first emergency gate is located in front of the working gate.

[0009] Preferably, it further includes a first maintenance valve, which is arranged at the second water flow channel and located in front of the flow regulating valve.

[0010] Preferably, it further includes a second maintenance valve, which is arranged at the second water flow channel and located behind the flow regulating valve.

[0011] Preferably, the first maintenance valve and the second maintenance valve have the same structure.

[0012] Preferably, it further includes a second emergency gate, which is arranged at the second water flow channel and located in front of the flow regulating valve.

[0013] Preferably, it further includes a third concrete breast wall, which is connected to the tower main body, and the second emergency gate is connected to the third concrete breast wall.

[0014] The beneficial effects of the present utility model are as follows: The working gate can separately control the first water flow channel through the structure form of its gate, and the flow regulating valve can separately control the second water flow channel through the structure form of its valve;

[0015] Therefore, when the required flow rate of the water diversion and regulation project is small, the flow regulating valve can be used alone to control the flow and release water. When the required flow rate of the water diversion and regulation project is large, the working gate can be selected to control the flow and release water alone, or the working gate and the flow regulating valve can be used in combination to release water;

[0016] By adopting the layout method of combining the gate and the valve, the intake tower structure can reasonably adopt the combined dispatching method of the gate and the valve to control the flow rate under different water intake levels and different water intake flow conditions, so as to achieve the purpose of accurately controlling the flow rate and reducing the project risk.

[0017] Compared with the traditional intake tower structure, the intake tower structure mentioned in this embodiment can adapt to the characteristics of large changes in water intake level and large changes in water intake flow rate in large-scale water diversion and regulation projects. During the actual operation process, the opening degrees of the gate and the valve can be adjusted under different water levels and different flow rates, so that under the premise of meeting the flow rate requirements, the opening degrees of the gate and the valve are both within a reasonable range, reducing the vibration generated during the water conveyance process and ensuring the operation safety of the gate and the valve.

[0030] Referring to Figures 1 to 3 , the present utility model provides a water intake tower structure based on combined regulation of gate valves, including a tower main body 1, a trash rack 2, a first concrete breast wall 3, a working gate 41, and a flow regulating valve 51;

[0031] The trash rack 2 is connected to the tower main body 1. The trash rack 2 can block a certain amount of dirt and debris in the water body. The first concrete breast wall 3 is connected to the tower main body 1, and the trash rack 2 is located in front of the first concrete breast wall 3. The tower main body 1 is provided with a dirt cleaning guide groove 11 in front of the trash rack 2, and water can first flow into the dirt cleaning guide groove 11;

[0032] The tower main body 1 forms a mutually separated first water flow channel 12 and a second water flow channel 13 behind the first concrete breast wall 3. The working gate 41 is arranged at the first water flow channel 12, and the flow regulating valve 51 is arranged at the second water flow channel 13;

[0033] The working gate 41 can independently control the first water flow channel 12 through the structure of its gate, and the flow regulating valve 51 can independently control the second water flow channel 13 through the structure of its valve;

[0034] Therefore, when the required flow rate of the water diversion project is small, the flow regulating valve 51 can be used alone to control the flow and discharge water. When the required flow rate of the water diversion project is large, the working gate 41 can be selected to control the flow and discharge water alone, or the working gate 41 and the flow regulating valve 51 can be used in combination to discharge water;

[0035] By adopting the layout method of combining gates and valves, the water intake tower structure can reasonably adopt the combined regulation method of gates and valves under different water intake levels and different water intake flow conditions, so as to achieve the purpose of accurately controlling the flow rate and reducing the engineering risks.

[0036] Compared with the traditional intake tower structure, the intake tower structure mentioned in this embodiment can adapt to the characteristics of large changes in the intake water level and large changes in the intake flow rate in large-scale water diversion projects. During the actual operation process, by adjusting the opening degrees of the gates and valves at different water levels and different flow rates, the opening degrees of the gates and valves can be within a reasonable range on the premise of meeting the flow requirements, reducing the vibration generated during the water conveyance process and ensuring the safe operation of the gates and valves.

[0037] As an optional implementation manner, it further includes a second concrete breast wall 43.

The first emergency gate 42 is located in front of the working gate 41. The working gate 41 can move vertically under the drive of the driving device. If the working gate 41 fails or needs to be overhauled and maintained, the first water flow channel 12 can be blocked by the first emergency gate 42. During daily use, the first emergency gate 42 remains in the open state.

[0039] As an optional implementation manner, it further includes a first maintenance valve 52 and a second maintenance valve 53;

[0040] The first maintenance valve 52 is arranged at the second water flow channel 13 and is located in front of the flow regulating valve 51. If the equipment corresponding to the second water flow channel 13 is damaged or needs to be repaired, the second water flow channel 13 can be blocked by the first maintenance valve 52.

[0041] The second maintenance valve 53 is arranged at the second water flow channel 13 and is located behind the flow regulating valve 51. If the equipment corresponding to the second water flow channel 13 is damaged or needs to be repaired, and at this time if the first flow channel is still working normally, the second water flow channel 13 can be blocked by the first maintenance valve 52 and the second maintenance valve 53 without affecting the normal operation of the first flow channel;

[0042] The first maintenance valve 52 and the second maintenance valve 53 cooperate with each other and can be flexibly selected and used according to the actual situation;

[0043] In this embodiment, the first maintenance valve 52 and the second maintenance valve 53 are preferably of the same structure, which is more convenient to use.

The third concrete breast wall 55 is connected to the tower main body 1, the second emergency gate 54 is connected to the third concrete breast wall 55, and the second emergency gate 54 is arranged at the second water flow channel 13 and in front of the flow regulating valve 51;

[0045] If some equipment at the second water flow channel 13 suddenly fails, or in the case where the first maintenance valve 52 or the second maintenance valve 53 needs to be overhauled and maintained, the second water flow channel 13 can be blocked by the second emergency gate 54. In daily use, the second emergency gate 54 remains in the open state.
