Description

Technical Field

[0001] The invention relates to the technical field of high-head radial gates, in particular to a water replenishment system of a high-hole radial gate water-stopping and pressure-charging system and a control method thereof. Background Art

[0002] High-head hydraulic curved steel gates are widely used in water conservancy projects, mainly for controlling water flow, regulating water levels and achieving water resource management. Such gates are usually installed in high dams or deep water areas. They have complex structures and need to have good water-stopping capabilities to ensure effective control of water bodies under normal operation and extreme conditions. However, due to long-term use, natural wear and tear, and environmental influences, the water-stopping system of the gate is prone to problems such as water seal aging and wear after a period of use, resulting in leakage and affecting its normal operation.

[0003] In order to ensure the effectiveness of the gate water-stop system, the traditional water-stop method usually relies on the pressure-charging system to compensate the water seal and maintain the closed state of the water seal. However, when the water level in front of the dam drops or the main water replenishment device of the water-stop system fails, the internal pressure of the water seal gradually decreases, resulting in a gradual weakening of the water-stop effect. Especially in some extreme cases, if the water-stop system cannot be supported by water replenishment in time, the water seepage of the gate will gradually increase, which may cause the gate to vibrate or even destructively damage in severe cases, which will not only threaten the structural safety, but also cause water resource loss and affect the safe operation of the downstream hydropower station.

[0004] In the prior art, some water replenishment schemes have been proposed for the water-stopping system of high-head hydraulic curved steel gates, but these schemes have several limitations. On the one hand, traditional water replenishment devices usually rely on a single water supply source. When the water level in front of the dam is insufficient, the water replenishment pressure cannot meet the system requirements; on the other hand, some water replenishment systems lack real-time monitoring functions, making it difficult to replenish water in time when the water pressure is lower than the set value, resulting in difficulty in ensuring the reliability of the gate water-stopping system. In addition, the existing system lacks an effective early warning device, which makes it difficult for operators to be informed of water pressure changes in a timely manner, posing a hidden danger to the water-stopping effect of the gate. Summary of the invention

[0005] In view of the above problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the first purpose of the present invention is to propose a high-aperture arc gate water-stopping and pressure-charging system that can solve the problem that traditional water replenishment devices rely on a single water source, have no emergency water replenishment measures, and cannot replenish water in time.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: a water replenishment system for a high-hole arc gate water-stopping pressurizing system, which includes a pressurized water seal; a main water replenishment component, including a high-level water tank and a first pipeline, the high-level water tank is arranged at the upper end of the pressurized water seal, and the first pipeline is connected to the pressurized water seal; an emergency water replenishment component, including a dam-front water intake pipe, an emergency pipeline, and a lifting pump, one end of the dam-front water intake pipe is connected to the dam-front water, and the other end is connected to the pressurized water seal, the emergency pipeline is connected in parallel with the dam-front water intake pipe, and the lifting pump is arranged on the emergency pipeline; a control component, including a monitoring module, a transceiver module, and an alarm module, the monitoring module is electrically connected to the transceiver module, and the alarm module is electrically connected to the transceiver module.

[0009] As a preferred solution of the water replenishment system of the high-aperture arc gate water-stopping and pressurizing system described in the present invention, a first solenoid valve is arranged on the water intake pipe in front of the dam, and the first solenoid valve is arranged on the part of the water intake pipe in front of the dam that is connected in parallel with the emergency pipeline.

[0010] As a preferred solution of the water replenishment system of the high-aperture arc gate water-stopping and pressurizing system of the present invention, a second solenoid valve is provided at both ends of the lifting pump.

[0011] As a preferred solution of the water replenishment system of the high-aperture arc gate water-stopping and pressurizing system of the present invention, wherein: the first solenoid valve and the second solenoid valve are both electrically connected to the transceiver module.

[0012] As a preferred solution of the water replenishment system of the high-hole arc gate water-stopping and pressurizing system described in the present invention, the monitoring module includes a pressure sensor and a liquid level sensor, the pressure sensor is arranged in the pressurized water seal, and the liquid level sensor is arranged in the high-level water tank.

[0013] As a preferred solution of the water replenishment system of the high-hole arc gate water-stopping and pressurizing system described in the present invention, wherein: the transceiver module includes a receiving module and a processing module, the receiving module is electrically connected to the pressure sensor and the liquid level sensor; the processing module is electrically connected to the receiving module, the first solenoid valve, the second solenoid valve, and the alarm module.

[0014] As a preferred solution of the water replenishment system of the high-aperture radial gate water-stopping and pressurizing system of the present invention, the alarm module is an audible and visual alarm.

[0015] The second object of the present invention is to propose a control method for a water replenishment system of a high-hole arc gate water-stopping and pressurizing system, which includes the following steps: real-time monitoring of the water level of a high-level water tank through a liquid level sensor, real-time monitoring of the water pressure in the pressurized water seal through a pressure sensor and transmitting the data to a receiving module; setting a liquid level threshold of the liquid level sensor, a pressure threshold of the pressure sensor and an alarm threshold in the processing module; the receiving module aggregates the data to the processing module, and when the water level is lower than the liquid level threshold, or the pressure sensor detects that the water pressure is lower than the pressure threshold, the processing module sends an instruction to open the first solenoid valve to start standby water replenishment; after opening the first solenoid valve, when the pressure value of the pressure sensor received by the receiving module continues to be lower than the pressure threshold, the processing module sends an instruction to close the first solenoid valve, open the second solenoid valve and the lifting pump, and replenish water through the emergency pipeline; when the water level and water pressure return to the preset range, the processing module stops the lifting pump and closes the first solenoid valve and the second solenoid valve in the water replenishment circuit; when the pressure value of the pressure sensor received by the receiving module reaches the alarm threshold, the alarm module sends an alarm signal.

[0016] As a preferred solution of the control method of the water replenishment system of the high-hole radial gate water-stopping and pressurizing system of the present invention, the liquid level threshold is set to 0, the pressure threshold is set to 0.55Mpa, and the alarm threshold is set to 0.4Mpa

[0017] The beneficial effect of the present invention is that when the water level in front of the dam is insufficient or the main water replenishment component cannot provide water, the scheme can achieve rapid water replenishment of the pressurized water seal through the lifting pump and the emergency pipeline to maintain the normal water-stopping effect of the gate. By setting up a pressure sensor and a liquid level sensor, the system can monitor the water level and water pressure in real time, and automatically start and stop the water replenishment process according to the preset threshold, effectively ensuring the stability of the water seal pressure. In addition, the alarm module will issue a warning in time when the water pressure is lower than the safe value, reminding the operator to take measures, thereby avoiding the waste of water resources and the risk of structural damage caused by leakage.

[0024] Example 1

[0025] Reference Figure 1 , which is the first embodiment of the present invention, and provides a water replenishment system for a high-aperture radial gate water-stopping and pressurizing system. The water replenishment system for a high-aperture radial gate water-stopping and pressurizing system includes a pressurizing water seal 100; a main water replenishment component 200, including a high-level water tank 201 and a first pipeline 202, the high-level water tank 201 is arranged at the upper end of the pressurizing water seal 100, and the first pipeline 202 is connected to the pressurizing water seal 100; an emergency water replenishment component 300, including a dam front water intake pipe 301, an emergency Pipeline 302, lifting pump 303, one end of the dam front water intake pipe 301 is connected to the dam front water, and the other end is connected to the pressurized water seal 100, the emergency pipeline 302 is connected in parallel with the dam front water intake pipe 301, and the lifting pump 303 is arranged on the emergency pipeline 302; the control component 400 includes a monitoring module 401, a transceiver module 402, and an alarm module 403, the monitoring module 401 is electrically connected to the transceiver module 402, and the alarm module 403 is electrically connected to the transceiver module 402

When the water pressure or water level is abnormal, the alarm module 403 is activated to remind the operator to take measures to avoid water seal decompression.

[0027] Example 2

[0028] Reference Figure 1 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0029] Specifically, the high-level water tank 201 is further provided with a water inlet pipeline 201a, and the water inlet pipeline 201a continuously inlets water to ensure that the water level in the high-level water tank 201 is kept constant within a range.

[0030] Specifically, a first solenoid valve 301a is provided on the water intake pipe 301 in front of the dam, and the first solenoid valve 301a is provided on the part of the water intake pipe 301 in front of the dam that is connected in parallel with the emergency pipeline 302;

[0031] The first solenoid valve 301a is used to control the opening and closing of the water intake channel. When the system needs emergency water replenishment, the first solenoid valve 301a is opened to ensure that water flows into the pressurized water seal 100; when water replenishment is not needed, the valve is closed to ensure stable water flow.

[0032] Specifically, a second solenoid valve 302a is provided at both ends of the lift pump 303, and its function is to quickly cut off the water flow when the system stops emergency water replenishment, to prevent excess water from entering the system, and to ensure stable water pressure.

[0033] Specifically, the first solenoid valve 301a and the second solenoid valve 302a are both electrically connected to the transceiver module 402, and can receive instructions through the transceiver module 402 to achieve precise switch control, so that the water flow control and monitoring system are linked to improve the response speed and automation of the system.

[0034] Specifically, the monitoring module 401 includes a pressure sensor 401 a and a liquid level sensor 401 b . The pressure sensor 401 a is disposed in the pressurized water seal 100 , and the liquid level sensor 401 b is disposed in the high-level water tank 201 .

[0035] Specifically, the transceiver module 402 includes a receiving module 402a and a processing module 402b, the receiving module 402a is electrically connected to the pressure sensor 401a and the liquid level sensor 401b; the processing module 402b is electrically connected to the receiving module 402a, the first solenoid valve 301a, the second solenoid valve 302a, and the alarm module 403;

[0036] The water pressure and water level data are transmitted to the processing module 402b in real time; the processing module 402b is connected to the solenoid valve and the alarm module 403 to facilitate immediate response when the pressure or water level is abnormal, and to notify the operator through the alarm module 403.

[0037] Example 3

[0038] Reference Figure 2, which is the third embodiment of the present invention, and provides an operation method of a water replenishment system of a high-aperture radial gate water-stop punching system, which comprises the following steps:

[0039] The water level of the high-level water tank is monitored in real time through the liquid level sensor 401b, and the water pressure in the pressurized water seal is monitored in real time through the pressure sensor 401a and the data is transmitted to the receiving module;

[0040] In the processing module 402b, a liquid level threshold of the liquid level sensor, a pressure threshold and an alarm threshold of the pressure sensor are set;

[0041] The receiving module 402a collects the data to the processing module. When the water level is lower than the liquid level threshold, or the pressure sensor detects that the water pressure is lower than the pressure threshold, the processing module 402b sends a command to open the first solenoid valve 301a to start standby water replenishment;

[0042] After the first solenoid valve 301a is opened, when the pressure value of the pressure sensor received by the receiving module 402a is still continuously lower than the pressure threshold, the processing module 402b sends an instruction to close the first solenoid valve 301a, open the second solenoid valve 302a and the lift pump 303, and replenish water through the emergency pipeline 302;

[0043] When the water level and water pressure return to the preset range, the processing module 402b stops the operation of the lift pump 303 and closes the first solenoid valve 301a and the second solenoid valve 302a in the water supply circuit;

[0044] When the pressure value of the pressure sensor received by the receiving module 402a reaches the alarm threshold, the alarm module 403 sends out an alarm signal;

[0045] Specifically, the liquid level threshold is set to 0, the pressure threshold is set to 0.55Mpa, and the alarm threshold is set to 0.4Mpa.

[0046] This method provides a double emergency water replenishment guarantee. First, the main water replenishment pipeline of the high-level water tank 201 is used to continuously supply water to the pressurized water seal 100 to ensure the pressure. When the main water replenishment pipeline fails, the first emergency water replenishment measure is activated to draw water from the front of the dam for pressure charging. When the water level in front of the dam is too low, the second emergency water replenishment measure is activated, and a lifting pump is used to extract water from the front of the dam for pressure charging. When all three fail, the alarm device is activated to enable the staff to respond quickly.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
