[0023] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0024] like Figure 2 As shown, in the relevant embodiment, a first oil cylinder 1 for driving the gate 100 to open and close is provided on the first side of the gate 100, and a second oil cylinder 2 for driving the gate 100 to open and close is provided on the second side of the gate 100. The first oil cylinder 1 and the second oil cylinder 2 act synchronously to drive the gate 100 to rotate to achieve opening and closing.

[0025] The first oil cylinder 1 and the second oil cylinder 2 have the same structure and control oil circuit, but due to the differences in structure and oil circuit, the first oil cylinder 1 and the second oil cylinder 2 are prone to inconsistent movements during operation.

[0026] like Figure 1 As shown, the embodiment of the present disclosure provides a method for correcting the deviation of an overflow gate 100, the method comprising:

[0027] S1: Acquire a first elevation of a first side of the gate 100 and a second elevation of a second side of the gate 100;

[0028] S2: Calculate the actual deviation between the first elevation and the second elevation;

[0029] S3: When the actual deviation value is greater than the preset deviation value, the correction level of the gate 100 is determined according to the difference between the actual deviation value and the preset deviation value;

[0030] S4: Determine the oil flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2 according to the correction level, and adjust the oil flow of the first oil cylinder 1 and / or the second oil cylinder 2 according to the oil flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2.

[0031] It can be understood that the elevation deviation between the first side and the second side of the gate 100 is used to determine the correction level of the gate 100, and different oil circuit flow adjustment amounts are determined according to different correction levels, and the oil circuit flow of the first cylinder 1 and / or the second cylinder 2 is adjusted according to the determined oil circuit flow adjustment amount, thereby achieving correction between the first cylinder 1 and the second cylinder 2, ensuring that the elevations on both sides of the gate 100 are consistent, and thus avoiding damage to the cylinders, gate 100, etc. due to excessive deviation, and ensuring higher hydraulic operation efficiency.

[0032] It should be noted that the method for obtaining the first elevation of the first side of the gate 100 and the second elevation of the second side of the gate 100 can be set according to actual needs and is not limited to this. For example, distance sensors, encoders and other sensors are respectively installed on the first side and the second side of the gate 100, and the sensors are used to detect the first elevation of the first side of the gate 100 and the second elevation of the second side of the gate 100.

[0033] Different differences between the actual deviation value and the preset deviation value correspond to different correction levels. The larger the difference, the higher the correction level, which in turn increases the oil flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2. Conversely, the smaller the difference, the lower the correction level, which in turn decreases the oil flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2. The corresponding model for the difference between the actual deviation value and the preset deviation value, the correction level, and the oil flow adjustment amount can be determined based on the actual structure and oil circuit of the gate 100, and is not limited to this.

[0034] When the actual deviation value is greater than the preset deviation value, it indicates that there is an inconsistent operation between the first cylinder 1 and the second cylinder 2. By adjusting the oil flow rate of the first cylinder 1 and / or the oil flow rate of the second cylinder 2, the deviation between the first cylinder 1 and the second cylinder 2 can be corrected, thereby ensuring the consistency of the elevation of both sides of the gate 100. The deviation correction can be achieved by adjusting the oil flow rate of the first cylinder 1, the oil flow rate of the second cylinder 2, or by adjusting the oil flow rate of the first cylinder 1 and the oil flow rate of the second cylinder 2 at the same time, without limitation.

[0035] In some embodiments, the method further comprises:

[0036] When the actual deviation value is greater than the preset deviation value, the piston displacement of the first oil cylinder 1 and the second oil cylinder 2 is determined to be the largest or the piston displacement is the smallest according to the first elevation and the second elevation;

[0037] Determine the oil flow adjustment amount of the first oil cylinder 1 and the second oil cylinder 2 with the largest piston displacement or the smallest piston displacement according to the correction level;

[0038] The oil flow rate of the first oil cylinder 1 or the second oil cylinder 2 with the largest piston displacement or the smallest piston displacement is adjusted according to the oil flow rate adjustment amount.

[0039] It can be understood that when the actual deviation value is greater than the preset deviation value, the one with the largest piston displacement in the first cylinder 1 and the second cylinder 2 is determined according to the first elevation and the second elevation, and the oil circuit flow adjustment amount of the one with the largest piston displacement in the first cylinder 1 and the second cylinder 2 is determined according to the correction level, and the oil circuit flow of the one with the largest piston displacement in the first cylinder 1 and the second cylinder 2 is adjusted according to the oil circuit flow adjustment amount, thereby ensuring that the elevations on both sides of the gate 100 are consistent.

[0040] When the actual deviation value is greater than the preset deviation value, the one with the smallest piston displacement in the first cylinder 1 and the second cylinder 2 is determined according to the first elevation and the second elevation, and the oil circuit flow adjustment amount of the one with the smallest piston displacement in the first cylinder 1 and the second cylinder 2 is determined according to the correction level, and the oil circuit flow of the one with the smallest piston displacement in the first cylinder 1 and the second cylinder 2 is adjusted according to the oil circuit flow adjustment amount, thereby ensuring that the elevations on both sides of the gate 100 are consistent.

[0041] In some embodiments, the method further comprises:

[0042] Determine the piston with the largest displacement in the first oil cylinder 1 and the second oil cylinder 2 according to the first elevation and the second elevation;

[0043] Determine the oil flow adjustment amount of the oil circuit of the first oil cylinder 1 and the second oil cylinder 2 with the largest piston displacement according to the correction level;

[0044] According to the oil flow adjustment amount, the oil flow of the first oil cylinder 1 and the second oil cylinder 2 with the largest piston displacement is reduced;

[0045] It can be understood that for the piston with the largest displacement between the first cylinder 1 and the second cylinder 2, by reducing its oil flow rate, its piston displacement speed and displacement distance can be reduced, thereby achieving the matching of the first cylinder 1 and the second cylinder 2, and ensuring that the elevations on both sides of the gate 100 are consistent.

[0046] In some embodiments, the method further comprises:

[0047] The one with the smallest piston displacement among the first cylinder 1 and the second cylinder 2 is determined according to the first elevation and the second elevation, and the oil circuit flow adjustment amount of the one with the smallest piston displacement among the first cylinder 1 and the second cylinder 2 is determined according to the correction level, and the oil circuit flow of the one with the smallest piston displacement among the first cylinder 1 and the second cylinder 2 is increased according to the oil circuit flow adjustment amount.

[0048] It can be understood that for the one with the smallest piston displacement between the first cylinder 1 and the second cylinder 2, by increasing its oil flow rate, its piston displacement speed and displacement distance can be increased, thereby achieving the matching of the first cylinder 1 and the second cylinder 2 and ensuring that the elevations on both sides of the gate 100 are consistent.

[0049] For example, when the first elevation is greater than the second elevation, so that the first cylinder 1 has the largest piston displacement, the oil circuit flow adjustment amount of the first cylinder 1 is determined according to the correction level, and the oil circuit flow of the first cylinder 1 is reduced according to the determined oil circuit flow adjustment amount. In addition, the second cylinder 2 has the smallest piston displacement, and the oil circuit flow adjustment amount of the second cylinder 2 can also be determined according to the correction level, and the oil circuit flow of the second cylinder 2 can be increased according to the determined oil circuit flow adjustment amount.

[0050] In some embodiments, the method further comprises:

[0051] When the difference between the actual deviation value and the preset deviation value is greater than the first deviation correction threshold and less than or equal to the second deviation correction threshold, the gate 100 is judged to be at the first deviation correction level;

[0052] Determining a first oil circuit flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2 according to the first deviation correction level, and adjusting the oil circuit flow of the first oil cylinder 1 and / or the second oil cylinder 2 according to the first oil circuit flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2;

[0053] The second deviation correction threshold is greater than the first deviation correction threshold.

[0054] It can be understood that when the difference between the actual deviation value and the preset deviation value is less than or equal to the first correction threshold, the oil circuit of the first cylinder 1 and the second cylinder 2 operates normally, and when the difference between the actual deviation value and the preset deviation value is greater than the first correction threshold and less than or equal to the second correction threshold, the gate 100 is judged to be the first correction level, and the oil circuit flow of the first cylinder 1 and / or the second cylinder 2 is adjusted according to the first oil circuit flow adjustment amount corresponding to the first correction level, thereby achieving the matching of the first cylinder 1 and the second cylinder 2, and ensuring the consistency of the elevation on both sides of the gate 100.

[0055] It should be noted that the first correction threshold and the second correction threshold can be set according to actual needs and there is no limitation on this. For example, the first correction threshold can be 10mm and the second correction threshold can be 30mm. That is to say, when the difference between the actual deviation value and the preset deviation value is greater than 10mm and less than or equal to 30mm, the gate 100 is judged to be the first correction level.

[0056] like Figure 2 As shown, in some embodiments, the method further includes:

[0057] Determining the regulating voltage of the servo proportional valve group 3 in the oil circuit of the first oil cylinder 1 and / or the second oil cylinder 2 according to the first deviation correction level;

[0058] Determine the adjustment opening of the servo proportional valve group 3 according to the adjustment voltage of the servo proportional valve group 3;

[0059] Controlling the adjustment opening of the servo proportional valve group 3 to adjust the oil flow of the first oil cylinder 1 and / or the second oil cylinder 2 according to the adjustment amount of the first oil flow;

[0060] The servo proportional valve group 3 is provided in the oil circuit, and the servo proportional valve group 3 is used to adjust the flow of the oil circuit.

[0061] It can be understood that by controlling the voltage of the servo proportional valve group 3 in the oil circuit of the first cylinder 1 and / or the second cylinder 2, the opening of the servo proportional valve group 3 is adjusted, and then the oil circuit flow of the first cylinder 1 and / or the second cylinder 2 is adjusted. Therefore, by controlling the servo proportional valve group 3 in the oil circuit, the matching of the first cylinder 1 and the second cylinder 2 is achieved, ensuring that the elevations on both sides of the gate 100 are consistent.

[0062] It should be noted that the control oil circuits of the first cylinder 1 and the second cylinder 2 both include: a servo proportional valve group 3 for adjusting the oil circuit flow, and the servo proportional valve group 3 may include: a servo proportional valve for adjusting the oil circuit flow and various valve bodies adapted to the servo proportional valve.

[0063] In some embodiments, the method further comprises:

[0064] When the difference between the actual deviation value and the preset deviation value is greater than the second deviation correction threshold and less than or equal to the third deviation correction threshold, the gate 100 is judged to be at the second deviation correction level;

[0065] determining a second oil circuit flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2 according to the second deviation correction level, and adjusting the oil circuit flow of the first oil cylinder 1 and / or the second oil cylinder 2 according to the second oil circuit flow adjustment amount of the first oil cylinder 1 and / or the second oil cylinder 2;

[0066] The third deviation correction threshold is greater than the second deviation correction threshold, and the second oil path flow adjustment amount is greater than the first oil path flow adjustment amount.

[0067] It can be understood that when the difference between the actual deviation value and the preset deviation value is greater than the second correction threshold and less than or equal to the third correction threshold, the gate 100 is judged to be the second correction level, and the oil flow of the first cylinder 1 and / or the second cylinder 2 is adjusted according to the second oil flow adjustment amount corresponding to the second correction level, thereby achieving the matching of the first cylinder 1 and the second cylinder 2, and ensuring that the elevations on both sides of the gate 100 are consistent.

[0068] It should be noted that the third correction threshold can be set according to actual needs and there is no restriction on this. For example, the third correction threshold can be 50mm, that is, when the difference between the actual deviation value and the preset deviation value is greater than 30mm and less than or equal to 50mm, the gate 100 is judged to be the second correction level.

[0069] like Figure 2 As shown, in some embodiments, the method further includes:

[0070] Determine the adjustment opening of the deviation correction oil return valve group 4 in the oil circuit of the first oil cylinder 1 and / or the second oil cylinder 2 according to the second deviation correction level;

[0071] Controlling the adjustment opening of the deviation-correcting oil return valve group 4 to adjust the oil flow of the first oil cylinder 1 and / or the second oil cylinder 2 according to the second oil flow adjustment amount;

[0072] The deviation-correcting oil return valve group 4 is arranged in the oil circuit, and the deviation-correcting oil return valve group 4 is used to adjust the return oil flow from the oil circuit to the oil tank.

[0073] It can be understood that by controlling the opening of the corrective return oil valve group 4 in the oil circuit of the first cylinder 1 and / or the second cylinder 2, the oil circuit flow of the first cylinder 1 and / or the second cylinder 2 is adjusted. Thus, by controlling the corrective return oil valve group 4 in the oil circuit, the matching of the first cylinder 1 and the second cylinder 2 is achieved, ensuring that the elevations on both sides of the gate 100 are consistent.

[0074] It should be noted that the control oil circuits of the first cylinder 1 and the second cylinder 2 both include: a correction return oil valve group 4 for adjusting the oil circuit flow rate, and the correction return oil valve group 4 may include: a two-position four-way valve for conducting the oil circuit oil to the oil tank, a cartridge valve for conducting the oil circuit oil to the oil tank, and various valve bodies adapted to the two-position four-way valve and the cartridge valve.

[0075] Among them, the correction oil return valve group 4 has a larger flow adjustment range than the servo proportional valve group 3, that is, when the gate 100 is at the first correction level, the flow adjustment method is fine adjustment, and when the gate 100 is at the second correction level, the flow adjustment method is coarse adjustment.

[0076] In some embodiments, the method further comprises:

[0077] When the difference between the actual deviation value and the preset deviation value is greater than the third deviation correction threshold, the oil circuit of the first oil cylinder 1 and the second oil cylinder 2 is closed to stop the operation of the gate 100 and issue a first alarm message.

[0078] It can be understood that when the difference between the actual deviation value and the preset deviation value is greater than the third correction threshold, it indicates that the elevation deviation on both sides of the gate 100 is too large. Therefore, the oil circuit of the first cylinder 1 and the second cylinder 2 is closed to stop the operation of the gate 100 to avoid damage to the gate 100, the cylinder, etc., and the first alarm message is issued to promptly remind the operating personnel to carry out maintenance.

[0079] It should be noted that the first alarm information can be sound information, light information, sound and light information, etc., and there is no limitation on this.

[0080] In some embodiments, the method further comprises:

[0081] Obtaining the oil circuit pressure of the first oil cylinder 1 and / or the second oil cylinder 2;

[0082] When the oil circuit pressure of the first oil cylinder 1 and / or the second oil cylinder 2 exceeds the preset pressure range, the oil circuit of the first oil cylinder 1 and the second oil cylinder 2 is closed to stop the operation of the gate 100 and issue a second alarm message.

[0083] It can be understood that when the oil circuit pressure of the first cylinder 1 and / or the second cylinder 2 exceeds the preset pressure range, it indicates that some equipment in the gate 100, cylinders, oil circuit and other facilities has failed. Therefore, the oil circuit of the first cylinder 1 and the second cylinder 2 is closed to stop the operation of the gate 100, thereby avoiding further damage to the gate 100, cylinders, etc., and a second alarm message is issued to promptly remind the operating personnel to carry out maintenance.

[0084] It should be noted that the method for obtaining the oil circuit pressure can be set according to actual needs and is not limited to this. For example, the oil circuit pressure can be obtained by relying on a pressure sensor, etc.

[0085] The second alarm information can be sound information, light information, sound and light information, etc., and there is no limitation on this.
