Description

Technical Field

[0001] The present invention relates to a water level alarm regulation method for a ship lock model, belonging to the technical field of water level control of ship lock models. Background Technique

[0002] A ship lock is a navigation structure set on a navigable river to help ships overcome the water level difference caused by building a dam. When the ship lock is filling with water, the high-position water body in the upstream enters the lock chamber through the water conveyance system, and the water level in the lock chamber rises until it is flush with the upstream; when the ship lock is discharging water, the water body in the lock chamber is discharged downstream through the water conveyance system until it is flush with the downstream to meet the needs of ships passing through the lock. The filling and discharging of the ship lock are completed by controlling the water conveyance valves. Due to complex hydrodynamic problems involving valves, water conveyance channels, etc. and the safety of ships berthed in the lock chamber, a valve control system that can simulate the prototype is often required. Through means such as model tests, in-depth research is carried out on the operation mode of the water conveyance valves to ensure the operation efficiency and safety of the ship lock.

[0003] In the existing invention authorization technology CN113110195A, a ship lock model control operating system, when the alarm button is pressed, the alarm operation interface is entered. In this interface, the water levels of each lock chamber are monitored in real time, and the over-limit values of the water levels of each lock chamber are set. When the water level of a certain lock chamber exceeds the set over-limit water level value, the system gives an alarm. At the same time, according to the set valve opening and closing speeds, the valve opening and closing operations are automatically performed, and the opening values of each valve and the water levels of each lock chamber are monitored in real time. In terms of the reaction treatment when the water level in a certain lock chamber exceeds the set over-limit water level value, the regulation is general and not comprehensive enough. There is an impact on the normal water level or the already critical water level of the adjacent or alternate downstream lock chambers due to the water discharge maintaining the normal water level in the first lock chamber, resulting in the problem of multiple alarm chaos and not being convenient for replenishing water to the downstream lock chambers with low water levels. Therefore, a water level alarm regulation method for a ship lock model is proposed for the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a water level alarm regulation method for a ship lock model to solve the above problems.

[0005] The present invention realizes the above purpose through the following technical solutions. A water level alarm regulation method for a ship lock model is as follows: Obtain the water levels, water level differences, and valve opening values of each lock chamber in the ship lock, and judge whether the water level of a certain lock chamber exceeds the alarm set value: If the water level of this lock chamber does not exceed the alarm set value, the regulation of the valve opening value operates normally; otherwise, close the front lock chamber, and call the ship lock model to enter the model parameter interface to set various parameters. The method of dividing the water volume exceeding the water level of this lock chamber by each lock to obtain the water volume distributed to each downstream lock chamber is used to give the valve opening parameters. The specific steps of this method are as follows: A1. Input the excess water volume of a lock chamber that exceeds the alarm setting value, the difference between the current water level of each lock chamber downstream and the corresponding alarm setting water level, and adjust the valve process curve of water diversion to each lock chamber downstream behind the lock chamber according to the actual on-site operation requirements through the ship lock model; A2. Set a gate valve opening range, starting from the first gate chamber to the last gate chamber downstream, and perform a difference test on the sum of the gradually rising water levels in each downstream gate chamber and the alarm over-water level value of the first gate; A3. Determine whether the water level in the alarm gate chamber has dropped to the normal level based on the difference detection change: If the difference detection change is a positive value, the water level in the alarm gate chamber has dropped to the normal level and the alarm is lifted. Otherwise, the gate valve opening value at the first downstream gate chamber is consistent with the gate valve opening value at the alarm gate chamber and water is diverted to the second downstream gate chamber, and this process is repeated until the alarm is completely lifted.

[0006] Preferably, in step A2, if the difference between the gradually rising water level of a downstream gate chamber and the alarm setting value is detected to be 0, the corresponding gate valve is opened to the maximum opening, and the gate valve opening of the next downstream gate chamber is interrupted to the maximum opening.

[0007] Preferably, when it is determined that the water level in a certain gate chamber exceeds the alarm setting value, an alarm is triggered and the water level in the gate chamber is lowered in real time, and the front gate is closed at the same time.

[0008] Preferably, when it is determined that the water level in the second gate chamber at the downstream end exceeds the alarm setting value, the system will sound an alarm, and any one of the front gates will be closed and the rear gate at the end will be opened.

[0009] Preferably, when the water level in a certain lock chamber exceeds the over-limit water level setting value, the system will alarm and automatically perform valve opening and closing operations according to the set valve opening and closing speeds.

[0010] Preferably, the model parameters are set for various parameters of each model, and specific parameter items are adjusted according to actual on-site operation requirements.

[0011] The beneficial effects of the present invention are: By distributing water to each gate downstream and setting the gate valve opening value, the gate chamber can be adjusted to the normal water level at a fast speed without causing the problem of each gate chamber exceeding the set water level; Avoid unnecessary release of water into the downstream river to maintain normal water levels in each lock chamber; It is convenient to replenish water sources in any downstream lock chamber with insufficient water level, and reduce the impact of overwater level or too low water level on the operation of the lock chamber.

Obviously, the embodiments described below are only some embodiments of the present invention, rather than all embodiments.

[0015] The following will further illustrate the technical solutions of the present invention with reference to the drawings and through specific implementation manners.

[0016] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0017] Please refer to Figure 1 As shown, a method for regulating and alarming the water level of a ship lock model is as follows: Obtain the water level, water level difference, and gate valve opening values of each chamber in the ship lock, and determine whether the water level of a certain chamber exceeds the alarm setting value: If the water level of this chamber does not exceed the alarm setting value, the regulation of the gate valve opening value operates normally; otherwise, close the front chamber, and call the ship lock model to enter the model parameter interface to set various parameters, and use the method of dividing the water volume exceeding the water level of this chamber into each downstream chamber one by one to obtain the water volume distributed to each downstream chamber. Given the gate valve opening parameters, the specific steps of this method are as follows: A1. Input the water volume exceeding the water level of a certain chamber that exceeds the alarm setting value, and the differences between the current water levels of each downstream chamber and the corresponding alarm setting water levels. The ship lock model adjusts the valve process curve for gradually distributing water to each downstream chamber behind this chamber according to the actual operation requirements on site; A2. Set a range of gate valve openings. Starting from the first chamber and ending at the last downstream chamber, detect the difference between the sum of the gradually rising water levels of each downstream chamber and the alarm over-water level value of the first chamber; A3. Detect changes based on the difference value and determine whether the water level in the alarm lock chamber has dropped to the normal water level: If the detected change in the difference value is zero, the water level in the alarm lock chamber has dropped to the normal water level and the alarm is lifted. Otherwise, the opening value of the lock valve at the first downstream lock chamber is kept the same as that at the alarm lock chamber, and water is diverted to the second downstream lock chamber, and so on until the alarm is completely lifted.

[0018] Further, in step A2, if the detected difference between the gradually rising water level in a certain downstream lock chamber and the alarm set value is 0, the opening of the corresponding lock valve reaches the maximum opening, and the opening of the lock valve in the next downstream lock chamber is intermittently adjusted to the maximum opening.

[0019] Further, when it is determined that the water level in a certain lock chamber exceeds the alarm set value, an alarm is given and the water level in the lock chamber is lowered in real time, and at the same time, the action of closing the upstream lock is carried out.

[0020] Further, when it is determined that the water level in the second lock chamber at the downstream end exceeds the alarm set value and the system gives an alarm, more than one upstream lock is closed and the last downstream lock is opened.

[0021] Further, when the water level in a certain lock chamber exceeds the over-limit water level set value, the system gives an alarm, and at the same time, the opening and closing of the valve are automatically carried out according to the set valve opening and closing speed.

[0022] Further, the model parameters are used to set the parameters of each model, and the specific parameter items are adjusted according to the actual operation requirements on site.

[0023] The advantages of this method for regulating the water level alarm of the ship lock model are as follows: By diverting water to each downstream lock and setting the opening value of the control lock valve, the water level in the lock chamber exceeding the set value is regulated to the normal water level quickly, and the problem of the water level in each lock chamber exceeding the set value will not occur; It avoids the situation of discharging water to the downstream river non-necessarily to maintain the normal water level of each lock chamber; It is convenient to supplement the water source of any downstream lock chamber with insufficient water level, and reduces the influence degree of over-water level or too-low water level on the operation of the lock chamber.

[0024] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
