DETAILED DESCRIPTION

[0024] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended for description and explanation of the present disclosure and are not intended to limit the present disclosure.

[0025] In the present disclosure, the orientation words such as "up, down, left, right" used without the opposite description generally refer to the up, down, left and right of the installation tool in the normal use state, and "inner, outer" refers to relative to the surface of the installation tool. In addition, the terms "first, second, third and fourth" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first, second, third and fourth" can explicitly or implicitly include one or more features. In the description of the present disclosure, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0026] In the wind turbine control system, the control system is the brain and nerve of the wind turbine, which ensures the safe and efficient operation of the wind turbine. The control system realizes the maximum wind energy capture by monitoring the wind conditions, adjusting the blade angle and generator output.

[0027] In the related art, the control system uses advanced algorithms such as model predictive control and adaptive control, and combines big data analysis to realize fine management. In this way, the control system can monitor the equipment state in real time and give early warning of potential failures.

[0028] With the progress of wind power technology, the control system will play an increasingly important, critical and irreplaceable role. The control system is divided into three levels according to different control targets and requirements: first, functional control, to ensure that the basic functions of the wind turbine subsystem are realized, so that the wind turbine meets the basic grid connection conditions; second, efficiency control, to obtain maximum wind energy and improve the power quality of the wind turbine; third, flexible control, to use fault ride-through technology, through grid adaptability control and load control, to enable the wind turbine to maintain stable power output when the grid voltage and frequency are unstable, while reducing mechanical load and prolonging the life of the generator set. With the long-term operation of the wind turbine, the controller in the control system has reduced operating performance, heating, and even high-temperature shutdown, which has a great safety hazard to the normal operation of the wind turbine.

[0029] In the related art, a tie is used to directly fix the cooling fan on the controller for forced cooling, and a switch is used to manually control the start and stop of the cooling fan.

[0030] However, the wind turbine is vibrated during operation, and the heat dissipation fan is often not fixed firmly, and the fan is loose and falls off, which is unreliable in operation. In addition, the switch is used to control the start and stop of the fan, and manual operation is required, which wastes manpower and is low in efficiency.

[0031] In view of the above problems, the present disclosure provides a mounting tool to enable the working temperature of the controller to be maintained in a normal range by the heat dissipation fan, thereby improving the safety performance of the wind turbine.

[0032] As shown in Figures 1 to 3 The first aspect of the present disclosure provides a mounting tool 100 for fixing and installing a heat dissipation fan 120 on a controller 110, the mounting tool 100 is provided with a fixing part 30 and formed with a air supply duct 20, the air supply duct 20 is provided with a first opening 21 and a second opening 22, the first opening 21 and the second opening 22 are respectively arranged at both ends of the air supply duct 20 in the extension direction, the fixing part 30 is arranged at the second opening 22 and used for fixedly connecting with the heat dissipation fan 120, and the first opening 21 is used for sending the airflow from the second opening 22 to the controller 110.

[0033] The heat dissipation fan 120 is used for generating airflow, which can be a forced air cooling fan, a water cooling fan or other types of fans, and the controller 110 is used for controlling the operation of the wind turbine, which is not specifically limited in the present disclosure.

[0034] The first opening 21 and the second opening 22 of the air supply duct 20 are in communication. In some embodiments, the longitudinal section of the air supply duct 20 can include an arc shape, a rectangular shape or other shapes, as long as it can meet the communication between the first opening 21 and the second opening 22, which is not specifically limited in the present disclosure.

[0035] In some embodiments, the fixing part 30 can be an adhesive member, which is fixed to the outer wall of the air supply duct 20 corresponding to the second opening 22, and the heat dissipation fan 120 is adhered to the air supply duct 20 by the adhesive member. It should be noted that in this embodiment, the airflow generating part of the heat dissipation fan 120 can be aligned with the second opening 22 during adhesion, so that the airflow generated by the heat dissipation fan 120 flows into the air supply duct 20 through the second opening 22.

[0036] In other embodiments, the fixing part 30 can be a clamping member, which includes a connecting plate and a threaded nut, and the connecting plate is provided with a threaded hole for passing through the threaded nut. The connecting plate is fixed to the outer wall of the air supply duct 20 corresponding to the second opening 22, and the extension direction of the threaded hole is aligned with the outer wall of the heat dissipation fan 120. In the case that the airflow generating part of the heat dissipation fan is aligned with the second opening 22, the threaded nut passes through the threaded hole and is tightened to abut against the outer wall of the heat dissipation fan 120.

[0037] In some embodiments, the controller 110 and the mounting tool 100 can be fixed on the workbench, and the position of the controller 110 requiring heat dissipation is aligned with the first opening 21 of the air supply pipe 20, so that the heat dissipation fan 120 dissipates heat for the controller 110.

[0038] In other embodiments, a mounting portion can be arranged at the position of the air supply pipe 20 corresponding to the first opening 21, and the controller 110 and the air supply pipe 20 are fixedly connected through the mounting portion.

[0039] For example, the mounting portion is a first mounting hole arranged at the position of the air supply pipe 20 corresponding to the first opening 21, a second mounting hole is arranged at the corresponding position of the controller, an iron hook is used to pass through the first mounting hole and the second mounting hole and is tightened, so that the controller and the air supply pipe 20 are fixedly connected. In this way, the first opening 21 and the second opening 22 are communicated, the heat dissipation fan 120 is fixed at the position of the air supply pipe 20 corresponding to the second opening 22, and the controller 110 is aligned with the first opening 21. When the heat dissipation fan 120 works to output airflow, the airflow can enter the air supply pipe 20 through the second opening 22 and then flow to the controller 110 through the first opening 21.

[0040] In the embodiments of the present disclosure, the first opening and the second opening are arranged at the two ends of the air supply pipe of the mounting tool, and the fixing portion is arranged at the second opening, so that the heat dissipation fan is fixed at the second opening of the air supply pipe. At the same time, the first opening is aligned with the controller, and then the airflow at the heat dissipation fan passes through the second opening, flows through the air supply pipe, and then enters the controller through the first opening. In this way, when the controller is vibrated during work, since the controller is only located at the first opening and is not fixedly connected with the air supply pipe, the air supply pipe and the heat dissipation fan will not be vibrated, so that the heat dissipation fan will not be loosened from the position of dissipating heat for the controller. Therefore, the problem that the heat dissipation fan and the controller are easily loosened by being fixed by a cable can be avoided, and the reliability and stability of the heat dissipation fan dissipating heat for the controller can be improved.

[0041] In the embodiments of the present disclosure, the mounting tool 100 can include a first part 101 and a second part 102 connected at an angle, and the first part 101 and the second part 102 jointly form the air supply pipe 20. The first part 101 is formed with a containing portion 40, and the containing portion 40 is in communication with the first opening 21 and the air supply pipe 20, so as to accommodate the controller 110. The fixing portion 30 is formed on the second part 102.

[0043] It should be noted that the radial size of the hole of the first part 101 and the second part 102 can be determined according to the actual production situation, and the embodiments of the present disclosure do not make specific limitations.

[0044] Among them, the end of the first part 101 away from the second part 102 forms a containing part 40, and the controller 110 is fixed in the containing part 40. The end of the second part 102 away from the first part 101 forms a fixed part.

[0045] In some embodiments, the containing part 40 is formed with a through hole, and the side end of the containing part 40 along the extension direction of the hole forms a first opening 21, and the controller 110 is partially installed in the containing part 40 and clamped through the first opening 21. The other side end surface of the containing part 40 is connected with the first part 101.

[0046] In other embodiments, the containing part 40 includes a bottom plate 1011 arranged opposite to the first opening 21 and a side plate extending along the edge of the bottom plate and surrounding the side of the bottom plate 1011. Among them, the bottom plate 1011 and the side plate form a containing space, and the side adjacent to the bottom plate forms a side opening. The end of the containing part 40 with the side opening is connected with the air supply pipeline 20 to guide the containing part 40 and the air supply pipeline 20. The controller 110 is partially installed in the containing space and clamped through the first opening 21.

[0047] In some embodiments of the present disclosure, the fixed part 30 is formed on the second part 102, and the technical solution can refer to the aforementioned embodiments of the fixed part 30 arranged at the second opening 22.

[0048] In the embodiments of the present disclosure, the first part 101 and the second part 102 are arranged at an angle to form an air supply pipeline. The containing part 40 is formed on the first part 101 to be fixedly connected with the controller 110, and the fixed part 30 is formed on the second part 102 to be fixedly connected with the heat dissipation fan 120. The problem that the controller is vibrated during work and causes the heat dissipation fan to fall in the related art is avoided. The heat dissipation fan 120 can be fixedly connected with the controller 110 through the air supply pipeline 20 and transmit airflow to the controller 110, so as to dissipate heat for the controller 110. Even if the controller 110 is vibrated, since the heat dissipation fan 120 is fixedly connected with the controller 110 through the air supply pipeline, the installation mode is firm and is not easy to loosen, and the reliability of the heat dissipation fan 120 dissipating heat for the controller 110 is improved.

[0049] In the embodiments of the present disclosure, the second part 102 includes a main body segment 1021 and an expansion segment 1022.

[0050] The main body section 1021 and the expansion section 1022 can be in a pipe structure, in other words, the opposite ends of the main body section 1021 and the expansion section 1022 are fixedly connected, and a channel is formed through the main body section 1021 and the expansion section 1022. Meanwhile, the end of the main body section 1021 away from the expansion section 1022 is connected to the end of the first part 101 away from the first opening 21.

[0051] The end of the expansion section 1022 away from the main body section 1021 is connected to the fixing part 30. The size of the channel of the expansion section 1022 gradually increases from the connection with the main body section 1021 to the connection with the fixing part 30.

[0052] In some embodiments, the fixing part 30 can be an adhesive piece, which is connected to the end face of the expansion section 1022 away from the main body section 1021, and the heat dissipation fan 120 is fixedly connected to the air supply pipe 20 through the adhesive piece.

It can be understood that the adhesive piece can include two arc-shaped plates, which are oppositely arranged on the end face of the expansion section 1022 away from the main body section 1021, so that the connection between the heat dissipation fan and the expansion section 1022 is more firm.

[0054] In other embodiments, the fixing part 30 can be a connecting hole formed on the wall of the end of the expansion section 1022 away from the main body section 1021. The size of the channel of the end of the expansion section 1022 away from the main body section 1021 matches the outer shape size of the heat dissipation fan 120, the side of the air flow outlet of the heat dissipation fan 120 is aligned with the channel of the end of the expansion section 1022 away from the main body section 1021, and the iron hook is passed through the connecting hole and the hole on the outer wall of the heat dissipation fan and is twisted to achieve the fixed connection between the heat dissipation fan 120 and the air supply pipe 20.

[0055] It should be noted that the opening of the expansion section 1022 gradually expands in the direction away from the main body section 1021, and the degree of expansion of the opening of the expansion section 1022 at each position can be determined according to actual conditions. For example, the outer wall surface of the expansion section 1022 can form a smooth arc surface, a slope, or a stepped shape, which is not specifically limited in the embodiments of the present disclosure.

[0059] It should be noted that the size of the surrounding edge, the extension size and the thickness size of the connection flange can be determined according to the size of the heat dissipation fan 120 and the actual production situation, wherein the size of the surrounding edge refers to the size of the end part of the expansion section 1022 for folding to form the connection flange, the extension size refers to the size of the outward folding of the end part of the expansion section 1022, and the thickness size refers to the size in the extension direction of the connection hole 31. The size of the surrounding edge can be equal to or less than the opening circumference of the end part of the expansion section 1022, the extension size can be matched with the size of the fastener and the required connection hole, and the thickness size can be consistent with the wall thickness of the expansion section 1022, and the embodiments of the present disclosure do not make specific limitations.

[0064] In the embodiments of the present disclosure, the connecting flange is formed by folding outward from the end of the expansion section 1022, and the connecting flange is fixedly connected with the heat dissipation fan 120, thereby achieving the fixed connection of the heat dissipation fan 120 with the air supply pipeline 20, and further achieving the fixed connection of the heat dissipation fan 120 with the controller 110, thereby avoiding the problem of unfirm connection of the controller with the heat dissipation fan through a cable tie, and improving the reliability of the heat dissipation fan 120 for dissipating heat for the controller 110.

[0074] The expansion segment 1022 includes a first connecting plate 10224 and a second connecting plate 10222, the first connecting plate 10224 is connected with the second side plate 10212 and is folded from the end of the second side plate 10212 towards the inclined plate 10211, the second connecting plate 10222 is connected with the first connecting plate 10224 and is folded from the end of the first connecting plate 10224 away from the second side plate 10212, the second connecting plate 10222 is connected with one of the two connecting flanges, and an avoiding space is formed between the first connecting plate 10224 and the connecting flange, which is used for avoiding the fastener.

[0075] Here, the first direction refers to the direction in which the first side plate 10211 faces away from the workbench. In other words, if the main body section 1021 is surrounded by four rectangular plates, the second side plate 10212 and the first side plate 10211 are two oppositely arranged rectangular plates, and the first side plate 10211 is used to be clamped to the workbench. At this time, the direction in which the second side plate 10212 faces the first side plate 10211 is the first direction.

[0076] In the case where the opening shape of the expansion section 1022 is a quadrilateral, the two end portions of the expansion section 1022 in the first direction can be the regions corresponding to the two opposite edges of the quadrilateral in the first direction.

[0077] It should be noted that, in order to avoid the problem that the two end portions of the expansion section 1022 are directly outwardly folded to form the connecting flanges, resulting in the existence of protrusions on the mounting tool 100, thereby affecting the work convenience of the workbench periphery, and even causing the workers to be injured by knocking against the protrusions, the end portion of the connecting flange away from the workbench is designed to be flush with the surface of the second side plate 10212. It can be understood that the connecting flange close to the workbench does not need to be designed to be flush with the surface of the first side plate 10211 because it is located below the workbench.

[0078] In some embodiments, the first connecting plate 10224 and the second connecting plate 10222 are provided to design the end portion of the two end portions of the expansion section 1022 in the first direction away from the first side plate 10211 to be flush with the surface of the second side plate 10212. In this way, the end portion of the connecting flange away from the first side plate 10211 can be flush with the surface of the second side plate 10212.

[0079] In other embodiments, the first connecting plate 10224 and the second connecting plate 10222 can be collectively arranged in an arc-shaped structure or other shapes, which are not specifically limited in the embodiments of the present disclosure.

[0080] In the embodiments of the present disclosure, by designing the end portion of one of the two connecting flanges to be flush with the surface of the second side plate 10212, the problem that the two end portions of the expansion section 1022 are directly outwardly folded to form the connecting flanges, resulting in the existence of protrusions on the mounting tool 100, thereby affecting the work convenience of the workbench periphery, and even causing the workers to be injured by knocking against the protrusions, is avoided, and the safety of the mounting tool 100 is improved.

[0081] In the embodiments of the present disclosure, the bottom plate 1011 and the first side plate 10211 are provided with a circular arc transition portion 103.

[0082] In other embodiments, the bottom plate 1011 and the first side plate 10211 can be directly connected, which is not specifically limited in the embodiments of the present disclosure.

[0083] In the embodiments of the present disclosure, the stress concentration problem at the connection between the bottom plate 1011 and the first side plate 10211 is avoided by arranging the circular arc transition part 103 between the bottom plate 1011 and the first side plate 10211.

[0084] It can be understood that the mounting tool 100 provided by the embodiments of the present disclosure can be integrally manufactured by injection molding or the like, and the embodiments of the present disclosure do not make specific limitations in this regard.

[0085] In some embodiments, the mounting tool 100 can be firmly mounted below the controller 110, and is connected to the lower heat dissipation fan 120 by using fasteners. The start and stop of the heat dissipation fan 120 are controlled by the temperature controller 50. When the temperature of the controller 110 is higher than 25°C, the heat dissipation fan 120 is started, and when the temperature of the controller 110 is lower than 25°C, the heat dissipation fan 120 is stopped. The heat dissipation fan 120 rotates to blow cooling air from the lower part to the bottom of the controller 110 through the air supply pipeline 20 of the mounting tool 100, thereby dissipating heat from the controller 110.

[0086] As shown in FIG. 1, Figures 1 to 4 The second aspect of the present disclosure provides a heat dissipation assembly 1000, which comprises the heat dissipation fan 120 and the aforementioned mounting tool 100. The heat dissipation fan 120 is fixedly connected to the fixing part 30 and is used for dissipating heat from the controller 110 through the air supply pipeline 20.

[0087] In the embodiments of the present disclosure, the technical solutions of the heat dissipation assembly 1000 can refer to the embodiments of the aforementioned mounting tool 100.

[0088] In the embodiments of the present disclosure, the heat dissipation assembly 1000 further comprises the temperature controller 50, and the heat dissipation fan 120 comprises the electric controller 121. The temperature controller 50 is electrically connected to both the electric controller 121 and the controller 110.

[0089] Here, the electric controller 121 is a power control part of the heat dissipation fan 120. When the electric controller 121 is conductive to the power supply part, the power supply part provides the heat dissipation fan 120 with the electric energy required for the output airflow of the heat dissipation fan 120. Then, the heat dissipation fan 120 can dissipate heat from the controller 110.

[0090] Correspondingly, the temperature controller 50 is used for controlling the start and stop of the electric controller 121 according to the temperature of the controller 110, thereby being capable of automatically controlling the start and stop of the heat dissipation fan 120 by the temperature controller 50, without manual start and stop, so as to reduce the cost.

[0091] In some embodiments, when the temperature of the controller 110 is greater than or equal to a first preset value, the temperature controller 50 controls the electric controller 121 to be conductive to the power supply, so that the heat dissipation fan 120 outputs the airflow. When the temperature of the controller 110 is less than the first preset value, the temperature controller 50 controls the electric controller 121 to be in a non-conductive state to the power supply.

[0092] For example, when the temperature of the controller 110 is greater than 25 degrees Celsius, the temperature controller 50 controls the heat dissipation fan 120 to output airflow; when the temperature of the controller 110 is less than or equal to 25 degrees Celsius, the temperature controller 50 controls the heat dissipation fan 120 to stop outputting airflow.

[0093] It should be noted that the first preset value is determined according to the suitable working temperature of the controller 110, for example, the highest value of the suitable working temperature range of the controller 110 can be taken as the first preset value, or 80%, 75% or 40% of the highest value of the suitable working temperature range can be taken as the first preset value, and the embodiments of the present disclosure do not make specific limitations in this regard.

[0094] In other embodiments, the electric controller 121 can include a first conduction mode and a second conduction mode, wherein the airflow temperature output by the heat dissipation fan 120 in the first conduction mode is higher than the airflow temperature output by the heat dissipation fan 120 in the second conduction mode. At this time, the temperature controller 50 can control the heat dissipation fan 120 to be in the first conduction mode or the second conduction mode to output airflow of different temperatures according to the temperature of the controller 110.

[0095] Wherein, when the temperature of the controller 110 is greater than or equal to the second preset value, the temperature controller 50 controls the electric controller 121 to be connected to the power supply and in the first conduction state, when the temperature of the controller 110 is greater than or equal to the third preset value and less than the second preset value, the temperature controller 50 controls the electric controller 121 to be connected to the power supply and in the second conduction state, and when the temperature of the controller 110 is less than the third preset value, the temperature controller 50 controls the electric controller 121 to be disconnected from the power supply.

[0096] It should be noted that the second preset value and the third preset value can be determined according to the suitable working temperature of the controller 110, for example, the highest value of the suitable working temperature range of the controller 110 can be taken as the second preset value, or 80%, 75% or 40% of the highest value of the suitable working temperature range can be taken as the third preset value, and the embodiments of the present disclosure do not make specific limitations in this regard.

[0097] In the embodiments of the present disclosure, by electrically connecting a temperature controller 50 at both ends of the controller 110 and the electric controller 121, the electric controller 121 is controlled to be connected or disconnected from the power supply according to the temperature of the controller 110, so as to automatically control the start and stop of the heat dissipation fan 120, thereby avoiding the high cost of manually controlling the start and stop of the heat dissipation fan 120 and reducing the control cost.

[0098] In the embodiments of the present disclosure, the heat dissipation assembly 1000 includes a power supply, the power supply supplies power to the electric controller 121 through a power supply circuit, the temperature controller 50 includes a protection switch 51 and a temperature control switch 52, and the protection switch 51 and the temperature control switch 52 are arranged on the power supply circuit.

[0099] Here, the protection switch 51 can be arranged in series with the temperature control switch 52 on the power supply circuit and electrically connected to the electric controller 121, wherein the protection switch 51 is used to be in an open state when the power supply circuit appears faults such as short circuit, open circuit and the like, so as to ensure the safety of the power supply circuit.

[0100] For example, when the lower wiring of the temperature control switch 52 appears short circuit, the protection switch 51 will automatically trip, and will not cause impact on the power consumption of other devices of the wind turbine.

[0101] In some embodiments, the temperature controller 50 can adopt NTK1-111 type temperature controller produced by CHNT factory of Chint, with rated voltage of AC 250 volts V and rated current of 10 amperes A. The temperature controller is arranged on the power supply circuit to control the automatic start and stop of the cooling fan 120.

[0102] In some embodiments, the power supply is AC power supply, including a live wire 502 and a zero line 501, wherein the live wire 502 is a 230V AC live wire, and the zero line 501 is an AC zero line.

[0103] Next, the working process of the cooling assembly 1000 provided by the embodiments of the present disclosure will be generally described.

[0104] In the process of the controller 110 controlling the operation of the wind turbine, the temperature controller 50 senses the working temperature of the controller 110. When the working temperature of the controller 110 reaches the first preset value, the temperature controller 50 controls the electric controller 121 to be conductive with the power supply, so that the cooling fan 120 outputs air flow. Since the cooling fan 120 is fixed at the second opening 22 of the air supply duct 20, the air flow output by the cooling fan 120 passes through the second opening 22, passes through the air supply duct 20 and is transmitted from the first opening 21 to the controller 110, so as to cool the controller 110 to an appropriate working temperature.

[0105] In the embodiments of the present disclosure, the mounting tool 100 and the heat dissipation assembly 1000 are provided, wherein the problem of unfirm fixation of the heat dissipation fan 120 and the controller 110 by using a cable tie is avoided by arranging the air supply pipeline 20 at the heat dissipation fan 120 and fixing the heat dissipation fan 120 and the air supply pipeline 20 at the second opening 22, the airflow can be transmitted to the controller 110 through the air supply pipeline 20 via the second opening 22 and the first opening 21, heat dissipation is realized, and the reliability of heat dissipation of the controller 110 by the heat dissipation fan 120 is improved. In addition, by electrically connecting a temperature controller 50 at both ends of the controller 110 and the electric controller 121, the electric controller 121 is connected or disconnected from the power supply according to the temperature of the controller 110, so as to realize automatic control of the start and stop of the heat dissipation fan 120, and the cost of manual control of the start and stop of the heat dissipation fan 120 is avoided, and the control cost is reduced.

[0106] In addition, the present scheme is based on the operation principle of the well-known controller 110 and the working condition, and the heat dissipation assembly 1000 for heat dissipation of the controller 110 is independently designed and manufactured, which can well guarantee the working temperature of the controller 110 and the operation performance of the controller 110, and increase the safety and reliability of the unit.

[0107] The preferred embodiments of the present disclosure are described in detail above with reference to the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0108] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not further describe various possible combination manners.

[0109] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
