Description

Technical Field

[0001] This invention relates to the field of wind power equipment protection technology, and in particular to a wind power outdoor equipment anti-falling ice protection structure. Background Technology

[0002] In cold regions during winter, the surface of outdoor wind power generation equipment often becomes covered with ice. As the weather changes, some of the ice may fall off, causing impact damage to other equipment. In severe cases, it may damage the circuit and cause the wind power equipment to stop generating electricity.

[0003] Existing technology CN117166820A discloses a wind power outdoor equipment anti-falling ice protection structure, including a truss main structure. The truss main structure is used to house the wind power outdoor equipment. The top of the truss main structure is densely covered with ice-breaking cones, and at least one net is installed below the ice-breaking cones and above the wind power outdoor equipment. This structure, with its truss main structure, uses ice-breaking cones to break up large ice blocks and then uses the net to buffer and intercept them. The truss main structure, ice-breaking cones, and net work together to achieve multiple layers of anti-falling ice protection. However, the ice-breaking effect of the above structure is poor and its level of intelligence is low.

[0004] Therefore, there is an urgent need to provide a fall-ice protection structure for wind power outdoor equipment that improves the efficiency and intelligence of ice-breaking protection for wind power equipment compared to existing technologies. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art and provides a fall-ice protection structure for wind power outdoor equipment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wind power outdoor equipment anti-ice protection structure includes a support component, a breaking component, a melting component, and a controller. The breaking component and the melting component are mounted on the support component. The breaking component includes multiple ice cones, a pressure sensor, and an ultrasonic generator. The multiple ice cones are all positioned above the support component, the pressure sensor is embedded above the support component, and the ultrasonic generator is used to vibrate the upper surface of the support component. The melting component includes a protective groove and a heater. The protective groove is located at the side end of the upper surface of the support component, and the heater is located at the inner bottom of the protective groove. The controller includes a first processing module and a second processing module. The first processing module is used to dynamically adjust the vibration frequency of the corresponding ultrasonic generator based on the pressure value detected by the pressure sensor. The second processing module is used to dynamically adjust the heating temperature of the corresponding heater based on the pressure value detected by the pressure sensor.

[0007] Furthermore, the support assembly includes a base, a frame, a protective top plate, a front protective plate, and a rear protective plate. Multiple frames are fixedly connected to the upper end of the base. The frames are divided into two rows. A protective top plate is fixed above all the frames in each row. The ends of two protective top plates that are close to each other are fixedly connected. Each protective top plate is inclined downward from the end that is close to each other to the end that is far away from each other. A front protective plate is fixedly installed on the front side of the protective top plate, and a rear protective plate is fixedly installed on the rear side.

[0008] Furthermore, multiple ice cones are installed above the protective top plate, and pressure sensors are embedded in the upper surface of the protective top plate.

[0009] Furthermore, the first processing module is also used to set the number of pressure sensors deployed around each ice cone and the distance between the pressure sensors and the ice cone.

[0010] Furthermore, the first processing module sets the number of pressure sensors deployed around each ice cone and the distance between the pressure sensors and the ice cone. Specifically, pressure sensors are evenly deployed above each protective top plate, and multiple different heights are set in multiple directions. Ice blocks with the same weight as the maximum bearing capacity of the protective top plate are freely dropped at each height in each direction. Then, the pressure values ​​detected by the pressure sensors within the set range of each ice cone are collected to form multiple data groups. Based on the location of the data points in each data group, the number of pressure sensors deployed around each ice cone and the distance between the pressure sensors and the ice cone are obtained.

[0011] Furthermore, for each ice cone, within all directions at the same height, the pressure values ​​detected by the pressure sensors within a set range constitute a data set for that ice cone, with multiple data sets corresponding to all heights. The data points within each data set corresponding to each ice cone are filtered, selecting the data points farthest from the ice cone's axis and the closest data points. A circular range is set with the ice cone as the center, the line connecting the farthest data point to the center as the radius, and the line connecting the closest data point to the center as the radius. The center of the circular range has the most pressure sensors, gradually decreasing towards the ice cone and away from it. The number of pressure sensors within each circular range is the same as the number of pressure sensors initially evenly distributed within that circular range.

[0012] Furthermore, for each ice cone, the set range is its axial length, and the distance between two adjacent ice cones is greater than the axial length of either of the two ice cones.

[0013] Furthermore, the first processing module dynamically adjusts the vibration frequency of the corresponding ultrasonic generator based on the pressure values ​​detected by the pressure sensors on each protective top plate, specifically judging the following situations: A first pressure threshold and a second pressure threshold are set, with the first pressure threshold being less than the second pressure threshold. At each moment, the pressure value detected by the pressure sensor on each protective top plate is collected. Zero-value pressure values ​​are discarded, and the remaining pressure values ​​are summed and averaged to obtain the detected pressure value at that moment. This detected pressure value is then compared with the first and second pressure thresholds, specifically as follows: (1) When the detected pressure value is 0, the ultrasonic generator is not started; (2) When the detected pressure value is greater than 0 and less than the first pressure threshold, start the ultrasonic generator and set the ultrasonic generator to the initial vibration frequency; (3) When the detected pressure value is greater than or equal to the first pressure threshold and less than the second pressure threshold, start the ultrasonic generator and set the ultrasonic generator to 1.2-1.6 times the initial vibration frequency; (4) When the detected pressure value is greater than or equal to the second pressure threshold, start the ultrasonic generator and make the ultrasonic generator twice the initial vibration frequency; The initial vibration frequency of the ultrasonic generator is the vibration frequency at which the falling ice is shattered when the weight of the falling ice covered by the protective top plate is 10% of the bearing pressure of the protective top plate.

[0014] Furthermore, the first pressure threshold and the second pressure threshold are specifically expressed by the following formula: ; ; In the above formula, Indicates the first pressure threshold. This indicates the second pressure threshold. This indicates the maximum bearing capacity of the protective roof, and N represents the total number of ice cones installed above each protective roof.

[0015] Furthermore, the second processing module is used to dynamically adjust the heating temperature of the corresponding heater based on the pressure value detected by the pressure sensor on each protective top plate, specifically judging the following situations: (1) When the detected pressure value is 0, the heater does not heat; (2) When the detected pressure value is greater than 0 and less than the first pressure threshold, start the heater and set the heater to the initial heating temperature; (3) When the detected pressure value is greater than or equal to the first pressure threshold and less than the second pressure threshold, start the heater and set the heater temperature to 1.4-1.8 times the initial heating temperature; (4) When the detected pressure value is greater than or equal to the second pressure threshold, start the heater and set the heater temperature to twice the initial heating temperature; The initial heating temperature of the heater is the heating temperature at which the weight of the falling ice in the protective tank is 10% of the bearing pressure of the protective top plate, which is the heating temperature for melting the falling ice.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a breaking component for initial ice breaking. After initial ice breaking, a pressure detector detects the pressure of the falling ice on the protective top plate. Based on the pressure value, the vibration frequency of an ultrasonic generator located below the protective top plate is dynamically adjusted to ensure the breaking of the falling ice. The broken ice falls into a collection tank, and the heating wire is adjusted to the most suitable heating temperature to heat the ice and melt it. The snow water in the collection tank can flow out and be collected, allowing the water resource to be reused. This invention can improve the efficiency and intelligence of ice breaking protection for wind power equipment. Attached Figure Description

[0019] The technical solution of the present invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] like Figure 1 As shown, the present invention provides a wind power outdoor equipment anti-ice protection structure, including a support component, a breaking component, and a melting component. The breaking component and the melting component are installed on the support component. The breaking component is used to initially break the falling ice and also to monitor the pressure of the falling ice on the support component and adjust the vibration frequency of the support component according to the pressure of the falling ice. The melting component is used to heat and melt the falling ice after it has been processed by the breaking component to form snow water for subsequent water resource treatment and utilization.

[0021] The support assembly includes a base 1, a frame 2, a protective top plate 3, a front protective plate 6, and a rear protective plate 7. Multiple frames 2 are fixedly connected to the upper end of the base 1. Preferably, two bases 1 are provided. Multiple frames 2 are fixedly provided along the length of the upper end of each base 1. A protective top plate 3 is fixed above all the frames 2 provided on the upper end of each base 1. The ends of the two protective top plates 3 that are close to each other are fixedly connected by a bracket 5. Each protective top plate 3 is inclined upward from the end of the frame 2 it is connected to to the end of the frame 2 it is far from. The front protective plate 6 is fixedly provided on the front side of the protective top plate 3, and the rear protective plate 7 is fixedly provided on the rear side. Both the front protective plate 6 and the rear protective plate 7 are vertically arranged.

[0022] The crushing assembly includes ice cones 8, pressure sensors, and ultrasonic generators. Multiple ice cones 8 are installed on the upper wall of each protective top plate 3, and multiple pressure sensors are installed on the upper end of each protective top plate 3. Each pressure sensor is embedded in the upper wall of the protective top plate 3, and an ultrasonic generator is installed on the lower wall of each protective top plate 3. Each ultrasonic generator dynamically adjusts its vibration frequency according to the pressure value detected by the pressure sensor installed on its corresponding protective top plate 3.

[0023] The melting assembly includes a protective trough 4 and a heater. Each protective top plate 3 is integrally connected to a protective trough 4 on its outer side. Each protective trough 4 has a heater at its bottom, preferably a heating wire. The heating wires at the bottom of each protective trough 4 extend along the length of the protective trough 4. The bottom of the protective trough 4 is an inclined surface, and a water outlet is provided at the lowest point of the inclined surface of the protective trough 4. The water outlet can be connected to an external water storage tank through a pipe. The ice blocks that are initially crushed or vibrated by the crushing assembly fall into the protective trough 4 along the inclined direction of the protective top plate 3. After being heated and melted by the heater in the protective trough 4, the melted snow water flows into the water storage tank through the water outlet for subsequent water resource treatment and utilization.

[0024] The crushing component and the melting component are connected to the controller, which is equipped with a first processing module and a second processing module. The first processing module is used to set the number of pressure sensors deployed around each ice cone 8 and the distance between the pressure sensors and the ice cone 8. The first processing module is also used to dynamically adjust the vibration frequency of the corresponding ultrasonic generator based on the pressure value detected by the pressure sensor on each protective top plate 3. The second processing module is used to dynamically adjust the heating temperature of the corresponding heating wire based on the pressure value detected by the pressure sensor on each protective top plate 3.

[0025] The first processing module is used to set the number of pressure sensors deployed around each ice cone 8 and the distance between the pressure sensors and the ice cone 8. Specifically, pressure sensors are first evenly deployed above each protective top plate 3. Then, multiple ice blocks of different heights are set around the device of this invention. At each height in each direction, ice blocks with the same weight as the maximum bearing capacity of the protective top plate 3 are freely dropped. The pressure values ​​detected by the pressure sensors within the set range for each ice cone 8 are then collected. For each ice cone 8, the set range is its axial length, and the distance between two adjacent ice cones 8 is greater than the axial length of either of the two ice cones 8. For each ice cone 8, in all directions at the same height... The pressure values ​​detected by the pressure sensors within the set range constitute a data set for the ice cone 8, i.e., a data set is generated for each height. The data points within the data set corresponding to each ice cone 8 are filtered to select the data points farthest from the axis of the ice cone 8 and the closest data points. A circular range is set with the ice cone 8 as the center, the line connecting the farthest data point to the center as the radius, and the line connecting the closest data point to the center as the radius. The pressure sensors are set at the center of the circular range with the most sensors, and the number gradually decreases towards the side closer to the ice cone 8 and away from the ice cone 8. However, the number of pressure sensors in each circular range is the same as the number of pressure sensors initially evenly distributed in the circular range.

[0026] The first processing module is also used to dynamically adjust the vibration frequency of the corresponding ultrasonic generator based on the pressure value detected by the pressure sensor on each protective top plate 3, specifically judging the following situations: A first pressure threshold and a second pressure threshold are set, with the first pressure threshold being less than the second pressure threshold. At each moment, the pressure value detected by the pressure sensor on each protective top plate 3 is collected. Zero-value pressure values ​​are discarded, and the remaining pressure values ​​are summed and averaged to obtain the detected pressure value at that moment. This detected pressure value is then compared with the first and second pressure thresholds, specifically: (1) When the detection pressure value is 0, the ultrasonic generator is not started.

[0027] (2) When the detected pressure value is greater than 0 and less than the first pressure threshold, start the ultrasonic generator and set the ultrasonic generator to the initial vibration frequency.

[0028] (3) When the detected pressure value is greater than or equal to the first pressure threshold and less than the second pressure threshold, start the ultrasonic generator and make the ultrasonic generator 1.2-1.6 times the initial vibration frequency.

[0029] (4) When the detected pressure value is greater than or equal to the second pressure threshold, start the ultrasonic generator and make the ultrasonic generator twice the initial vibration frequency.

[0030] The first pressure threshold and the second pressure threshold are specifically expressed by the following formula: ; ; In the above formula, Indicates the first pressure threshold. This indicates the second pressure threshold. This indicates the maximum bearing capacity of the protective roof, and N represents the total number of ice cones installed above each protective roof.

[0031] The second processing module is used to dynamically adjust the heating temperature of the corresponding heating wire based on the pressure value detected by the pressure sensor on each protective top plate 3, specifically judging the following situations: (1) When the detection pressure value is 0, the heating wire does not heat.

[0032] (2) When the detected pressure value is greater than 0 and less than the first pressure threshold, start the heating wire and set the heating wire to the initial heating temperature.

[0033] (3) When the detected pressure value is greater than or equal to the first pressure threshold and less than the second pressure threshold, start the heating wire and make the heating wire temperature 1.4-1.8 times the initial heating temperature.

[0034] (4) When the detected pressure value is greater than or equal to the second pressure threshold, start the heating wire and make the heating wire temperature twice the initial heating temperature.

[0035] The initial vibration frequency of the ultrasonic generator is such that when the weight of the falling ice covered by the protective top plate 3 is 10% of the bearing pressure of the protective top plate 3, it can break the falling ice; the initial heating temperature of the heating wire is such that when the weight of the falling ice in the protective trough 4 is 10% of the bearing pressure of the protective top plate 3, it can melt the falling ice.

[0036] This invention uses a breaking component for initial ice breaking. After initial ice breaking, a pressure detector detects the pressure of the falling ice on the protective top plate 3. Based on the pressure value, the vibration frequency of the ultrasonic generator located below the protective top plate 3 is dynamically adjusted to ensure the breaking of the falling ice. The broken ice falls into a collection tank, and the heating wire is adjusted to the most suitable heating temperature to heat the ice and melt it. The snow water in the collection tank can flow out and be collected, allowing the water resources to be utilized later. This invention can improve the efficiency and intelligence of ice breaking protection for wind power equipment.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
