[0080] like Figure 1 As shown, a method for controlling an automatic drainage system of a mixed tower fan tower base according to a preferred embodiment of the present application includes:

[0081] S101: setting a plurality of monitoring points according to the structural parameters of the drainage pit, wherein the monitoring points are provided with water level monitoring modules;

[0082] S102: judging whether to generate a monitoring instruction according to the state parameters of the sensing module, and the water level monitoring module obtaining water level data in the sump according to the monitoring instruction;

[0083] S103: Setting working parameters of the drainage unit according to the water level data;

[0084] The process of determining whether to generate a monitoring instruction includes:

[0085] Preset primary state and secondary state;

[0086] Determine the real-time status of the sensing module;

[0087] If the real-time status is level 1, no monitoring instruction is generated;

[0088] If the real-time status is the secondary status, a monitoring instruction is generated.

[0089] Specifically, when obtaining water level data in the sump, it includes:

[0090] Preset judgment time t;

[0091] Setting the time node for obtaining the monitoring instruction as the first time node;

[0092] Generate a second time node according to the first time node of the determination time t;

[0093] According to the first time node, the first-level water level height of each monitoring point is obtained, and the first-level water level height sequence A1 is established, A1=(a 11 , a 12 …a 1i …a 1n ), where a 1i is the first-level water level height of the ith monitoring point; n is the number of monitoring points;

[0094] According to the second time node, the secondary water level height of each monitoring point is obtained, and the secondary water level height sequence A2 is established, A2=(a 21 , a 22 …a 2i …a 2n ), where a 2i is the secondary water level height of the ith monitoring point.

[0095] Specifically, the judgment time can be set according to historical parameters. By setting the judgment time, two sets of water level height data are collected to determine the current water flow and water flow speed flowing into the sump.

[0096] Specifically, multiple monitoring points can be set according to the structural parameters of the sump, so as to accurately monitor the water level in the sump.

[0097] Specifically, in the above embodiment, by adding a sensing module, the water level monitoring module is activated only after the water level reaches a predetermined height, thereby reducing the overall monitoring and operation and maintenance costs while ensuring the efficiency of water level monitoring.

[0098] In some embodiments of the present application, when setting the working parameters of the drainage unit according to the water level data, it includes:

[0099] Generate a water level evaluation value f according to the primary water level height series and the secondary water level height series;

[0100]

[0101] Among them, e1 is the preset first weight coefficient; e2 is the preset second weight coefficient; Q1 is the preset first fixed coefficient; Q2 is the preset second fixed coefficient; e3 is the preset third weight coefficient; Q3 is the preset third fixed coefficient; Δa2 is the average value of all data in the secondary water level height series;

[0102] Set the drainage speed and feedback time node according to the water level rating value f;

[0103] The feedback data of the sump water level is obtained according to the feedback time node, and it is determined whether to generate a correction instruction based on the feedback data.

[0104] Specifically, by presetting the first fixed coefficient, the second fixed coefficient and the third fixed coefficient, each parameter in the model is normalized so that each parameter is within the same value range.

[0105] Specifically, a corresponding water level evaluation value is generated based on the collected water level height data. The larger the water level evaluation value is, the larger the amount of water flowing into the current sump is, and the accumulated water in the sump needs to be discharged in time.

[0106] Specifically, when setting the drainage speed, include:

[0107] Preset a first water level evaluation value interval (F1, F2), a second water level evaluation value interval (F2, F3) and a third water level evaluation value interval (F3, F4);

[0108] If the water level evaluation value f is within the preset first water level evaluation value interval, the drainage speed v is set to the preset first drainage speed V1, that is, v=V1;

[0109] If the water level evaluation value f is within the preset second water level evaluation value interval, the drainage speed v is set to the preset second drainage speed V2, that is, v=V2;

[0110] If the water level evaluation value f is within the preset third water level evaluation value interval, the drainage speed v is set to the preset third drainage speed V3, that is, v=V3; and V1<V2<V3.

[0111] Specifically, by setting multiple water level evaluation value intervals, gradient adjustment of the drainage speed is achieved according to the real-time water level evaluation value, thereby reducing the overall operation and maintenance cost while ensuring the drainage efficiency.

[0112] It can be understood that in the above embodiment, a sump is constructed at the bottom of the wind turbine tower base, and a sensing module is added to the sump. When the water level in the sump reaches a preset position, the sensing module is energized and sends a monitoring instruction to the central control unit. The central control unit sets the working parameters of the drainage unit according to the real-time water level, realizes automatic drainage of the tower base, ensures the normal operation of the mixed tower wind turbine equipment, and improves equipment reliability.

[0113] In a preferred embodiment of the present application, when determining whether to generate a correction instruction according to feedback data, it includes:

[0114] Generate efficiency evaluation value b according to the water level feedback data at the current feedback time node;

[0115] Preset a first efficiency evaluation value threshold B1;

[0116] If b<B1, a correction instruction is generated, a compensation coefficient is set according to the correction instruction, and the drainage speed between the current feedback time node and the next feedback time node is corrected according to the compensation coefficient;

[0117] If b>B1, generate the average water level height h of the current feedback time node, and preset the safe water level height H1. If h

[0118] Specifically, the first-level control instruction is to turn off the water pump and stop drainage.

[0119] ​Specifically, when the efficiency evaluation value is lower than the preset value, it means that the water level in the current sump is rising or stable. By setting the compensation coefficient, the drainage speed is increased to avoid a large amount of water accumulation in the sump.

[0120] Specifically, when generating the efficiency evaluation value b, it includes:

[0121]

[0122] Among them, e4 is the preset fourth weight coefficient; e5 is the preset fifth weight coefficient; Q4 is the preset fourth fixed coefficient; Q5 is the preset fifth fixed coefficient; di is the actual water level height of the i-th monitoring point at the current feedback time node; d'i is the actual water level height of the i-th monitoring point at the previous feedback time node; Δdi is the expected water level height of the i-th monitoring point at the current feedback time node.

[0123] Specifically, by presetting the third fixed coefficient, the fourth fixed coefficient normalizes each parameter in the model so that each parameter is in the same value range.

[0124] Specifically, the larger the efficiency evaluation value, the higher the current drainage efficiency and the faster the water level in the sump drops.

[0125] It can be understood that in the above embodiment, when draining water, the drainage speed of the drainage unit is corrected in time by periodically feeding back the real-time water level height, thereby avoiding excessive water accumulation at the bottom of the tower base, improving the degree of automation of drainage, and reducing equipment maintenance costs.

[0138] Specifically, the sensing module is preferably a float, a proximity switch and a relay, wherein the height of the proximity switch is the height of the warning water level, and when the water level in the sump rises, the float will hit the proximity switch, thereby energizing the relay. At this time, the sensing module is in the secondary state, and when the float is disconnected from the proximity switch, it is in the primary state.

[0139] Specifically, the water level monitoring module is preferably a water level sensor.

[0140] Specifically, the second processing module is used for:

[0152] Specifically, the third processing module is also used for:
