In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0018] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides a wind turbine generator with a de-icing warning mechanism, such as Figure 1-Figure 4 As shown, it includes: a base plate 1, a bracket 2 is installed on the upper end of the base plate 1, a working shell 3 is installed on the upper end of the bracket 2, a generator 32 is arranged in the working chamber 31 inside the working shell 3, the discharge motor 42 shaft of the generator 32 is connected to the rotating cylinder 4 through a rotating shaft 1 33, a rotation sensing alarm module is arranged on the rotating shaft 1 33, a plurality of blades 5 are arranged on the rotating cylinder 4, and a de-icing mechanism 9 is arranged in the blades 5.

[0019] The working principle and beneficial effects of the above technical solution are as follows: the bottom plate 1 fixes and supports the bracket 2, the bracket 2 fixes and supports the working shell 3, the working shell 3 fixes and supports and protects the generator 32 therein, the external wind exerts force on the multiple blades 5, the multiple blades 5 drive the rotating cylinder 4 to rotate, the rotating cylinder 4 drives the generator 32 to generate electricity by driving the rotating shaft 1 33, when a certain amount of ice and snow accumulates on the blades 5, the rotation efficiency of the blades 5 is reduced, the rotation sensing alarm module senses the reduction in the rotation efficiency of the blades 5, when the blades 5 stop rotating, the de-icing mechanism 9 starts to operate to melt the ice and snow accumulated on the blades 5, thereby reducing the load of the wind turbine 32, restoring the power generation efficiency, and preventing the blades 5 from being frozen, resulting in mechanical failure, equipment damage or safety accidents.

[0020] Example 2 On the basis of Example 1, Figure 1-Figure 4As shown, a cavity 41 is provided inside the rotating cylinder 4, and a discharger 42 is fixedly provided in the cavity 41. The discharger 42 is fixedly connected to a bevel gear 1 43. The bevel gear 1 43 is evenly meshed with a plurality of bevel gears 2 44 in the circumferential direction. The plurality of bevel gears 2 44 are fixedly connected to a plurality of fixed shafts 45 in a one-to-one correspondence. The fixed shaft 45 passes through the side end of the cavity 41 and is fixedly connected to the blade 5. The generator 32 is fixedly connected to a mounting plate 1 46. The mounting plate 1 46 is fixedly installed in the working cavity 31- inside the working shell 3.

[0021] The working principle and beneficial effects of the above technical solution are as follows: the discharger 42 drives the bevel gear 1 43 to rotate, the bevel gear 1 43 drives the bevel gear 2 44 to rotate, the bevel gear 2 44 drives the fixed shaft 45 to rotate, the fixed shaft 45 drives the blade 5 to rotate with the fixed shaft 45 as the center, and the windward angle of the blade 5 is adjusted, thereby changing the rotation speed of the blade 5 and the rotating cylinder 4 connected thereto, so that the rotation speed of the discharger 42 shaft is maintained at the target rotation speed, and the target rotation speed of the discharger 42 shaft is the required rotation speed of the discharger 42 shaft under the rated power of the generator 32. When the wind force level is too high and the rotation speed of the discharger 42 shaft of the generator 32 is too large, the discharger 42 is controlled to work, and the rotation speed of the discharger 42 shaft is reduced by changing the windward angle of the blade 5, so as to protect the generator 32, and solve the technical problem that when the wind force level is too high, the rotation speed of the discharger 42 shaft of the generator 32 is too fast, which seriously affects the service life of the generator 32.

[0022] Example 3 On the basis of Example 2, Figure 1-Figure 4 As shown, the working chamber 31 is connected to a ventilation mechanism 6, which includes an air inlet 61 arranged at the side end of the working shell 3, a filter screen 62 is obliquely arranged corresponding to the air inlet 61, an air outlet 63 is arranged at the rear end of the working shell 3, a rotating shaft 65 is rotatably arranged in the air outlet 63, and the rotating shaft 65 is fixedly connected to the air outlet plate 64, and the air inlet 61, the working chamber 31 and the air outlet 63 are connected in sequence.

[0023] The working principle and beneficial effects of the above technical solution are as follows: by setting the air inlet 61 and the air outlet 63, the air in the working chamber 31 circulates, which is convenient for heat dissipation of the generator 32; by setting the filter 62, dust and impurities from the outside are prevented from entering the working chamber 31 and affecting the service life of the parts in the working chamber 31; an air outlet plate 64 is set at the air outlet 63, and the air outlet plate 64 is set at an angle. The air outlet plate 64 can only rotate when the air in the working chamber 31 is discharged to the outside, and the outside air cannot enter the working chamber 31 through the air outlet 63. The setting of the air outlet plate 64 guides the flow direction of the air, so that the air can flow along the air inlet 61, the working chamber 31 and the air outlet 63 in sequence.

[0024] Example 3 On the basis of Example 2, Figure 1-Figure 4 As shown, the lower end of the bottom plate 1 is connected with a fixing mechanism 7, and the fixing mechanism 7 includes a mounting hole 71 set at the upper end of a base 78, a sealing plate 1 72 is slidably provided in the mounting hole 71, and the mounting hole 71 cooperates with a fixing column 73 at the lower end of the bottom plate 1, and the left and right ends of the fixing column 73 are symmetrically provided with fixing grooves 74, and the left and right sides of the mounting hole 71 are symmetrically connected with sealing grooves 75, and the sealing groove 75 is connected with a sealing cavity 1 76 through a passage 3, and the sealing cavity 1 76 is connected with a sealing cavity 2 77 through a passage 2, and the front and rear sides of the sealing cavity 2 77 are symmetrically provided with threaded sleeves 79, and the threaded sleeves 79 are correspondingly threadedly connected with the threaded sections of the fixing bolts 85, and the fixing bolts 85 are threadedly connected with the fixing holes on the bottom plate 1, and the sealing cavity 1 76 is connected with the mounting hole 71 through a passage 1; The fixing block 80 is also provided with a sliding arrangement in the sealing groove 75, and the fixing block 80 is matched with the fixing groove 74, and the end of the fixing block 80 away from the bracket 2 is fixedly connected with the sealing plate 2 82 through a push rod 81, and the sealing plate 2 82 is slidably connected with the sealing groove 75, and a spring 3 83 is fixedly arranged between the fixing block 80 and the fixing groove 74, and a clamping hole 84 is provided at the upper end of the fixing block 80, and the clamping hole 84 is matched with the cylindrical section of the fixing bolt 85, and the cylindrical section of the fixing bolt 85 passes through the opening and enters the sealing groove 75, and the opening is connected and arranged between the sealing cavity 2 77 and the sealing groove 75, and the cylindrical section of the fixing bolt 85 is matched with the circular holes distributed in the front and rear of the matching block 1 86, and the matching block 1 86 is slidably connected with the sealing cavity 2 77, and a plurality of springs 4 are fixedly arranged between the matching block 1 86 and the sealing cavity 2 77, and the inclined end of the matching block 1 86 is slidably connected with the inclined end of the matching block 2 87, and the matching block 2 87 is slidably arranged in the sealing cavity 2 77.

[0025] The working principle and beneficial effects of the above technical solution are as follows: the base 78 is fixed to the installation ground of the wind turbine 32. When the wind turbine 32 of the present invention is installed on the base 78, the fixing column 73 is first inserted into the installation hole 71 for positioning. The fixing column 73 drives the sealing plate 72 to slide along the installation hole 71, and the air in the space formed by the sealing plate 72 and the installation hole 71 is pressed into the sealing cavity 76 through the passage 1. At this time, the air pressure in the sealing cavity 76 increases until the sealing plate 72 stops moving. At this time, The fixing groove 74 corresponds to the fixing block 80. In the initial state, the fixing block 80 is in the sealing groove 75. As the air pressure in the sealing chamber 1 76 increases, the gas is sent into the sealing groove 75 through the passage 3, so that the air pressure in the sealing groove 75 increases. The sealing plate 2 82 pushes the fixing block 80 to move a certain distance through the push rod 81, and the spring 3 83 begins to stretch. At this time, the fixing bolt 85 is matched with the bottom plate 1 and the base 78. The threaded sleeve 79 in the base 78 is threadedly connected with the fixing bolt 85. The outer diameter of the threaded section of the fixing bolt 85 is large. The diameter of the cylindrical section of the fixing bolt 85 is smaller than the inner diameter of the circular hole. After the cylindrical section of the fixing bolt 85 is matched with the circular hole of the matching block 1 86, the matching block 1 86 is pushed downward, and the spring 4 is compressed to make the matching block 2 87 move. The matching block 2 87 sends the air in the sealing groove 75 into the sealing groove 75 through the passage 2, the sealing cavity 1 76 and the passage 3, and continues to push the fixing block 80 to move through the sealing plate 2 82 until the fixing block 80 is fully matched with the fixing groove 74. At this time, the clamping hole 84 is connected to the corresponding opening. As the fixing bolt 85 and the matching block 1 86 continue to move downward, the matching block 2 87 continues to move, so that the air pressure in the sealing groove 75 is greater. At the same time, the fixing bolt 85 cooperates with the clamping hole 84 of the fixing block 80, further improving the matching stability between the fixing block 80 and the fixing groove 74. The matching connection between the fixing block 80 and the fixing groove 74 makes the fixing column 73 stably set in the mounting hole 71, thereby completing the connection between the bottom plate 1 and the base 78, and improving the connection stability between the wind turbine 32 and the base 78; When disassembling the wind turbine 32, the fixing bolt 85 is screwed out, and the matching block 1 86 is restored to its original position under the elastic action of the spring 4, driving the matching block 2 87 to restore its original position. At this time, the air pressure in the sealing chamber 1 76 is reduced. At this time, the fixing block 80 moves a certain distance toward the sealing groove 75 under the elastic action of the spring 3 83, and the air in the sealing groove 75 enters the sealing chamber 2 77 through the passage 3, the sealing chamber 1 76 and the passage 2. The fixing block 80 is no longer fully matched with the fixing groove 74, and it is more labor-saving when pulling the fixing column 73 upward. The fixing block 80 and the sealing groove 75 are arc-shaped The structure is convenient for pulling out the fixing column 73, and as the fixing column 73 is pulled out, the fixing column 73 squeezes the fixing block 80 into the sealing groove 75, and the fixing block 80 is restored to its original position under the elastic action of the spring three 83. At this time, the gas in the sealing groove 75 enters the mounting hole 71 through the passage three, the sealing cavity one 76 and the passage one, so that the sealing plate one 72 is restored to its original position. The setting of the base 78 improves the fixing effect of the wind turbine 32, and avoids the use of bolts alone to fix the wind turbine 32. If the bolts become loose after long-term use, it is easy to cause the wind turbine 32 to tilt or even collapse.

[0026] Example 6 On the basis of Example 5, Figure 1-Figure 4 As shown, the de-icing mechanism 9 includes a limit plate 91, which is made of metal. A plurality of the limit plates 91 are fixedly arranged on the inner wall of a de-icing cavity 92 opened in the blade 5. A resistance wire 93 is fixedly arranged in the plurality of limit plates 91, and the resistance wire 93 is electrically connected to the discharge machine 42.

[0027] The working principle and beneficial effects of the above technical solution are as follows: when the blade 5 is controlled to stop rotating, the inner wall of the de-icing chamber 92 opened in the blade 5 fixes the multiple limit plates 91, and the multiple limit plates 91 fix the resistance wire 93. The discharger 42 energizes the resistance wire 93, and the resistance wire 93 generates heat and transfers the heat to the blade 5 through the limit plate 91. The ice and snow accumulated on the blade 5 are melted by the heat, thereby preventing the accumulated ice and snow from damaging the wind turbine 32.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
