Description
Technical Field
[0001] The invention relates to the technical field of wind power generation equipment, in particular to a circulating cooling device for wind power generation. Background Art
[0002] Wind power generation uses wind power to drive the windmill blades to rotate, and then increases the rotation speed through a speed increaser to drive the generator to generate electricity. Wind power generation devices generally include wind rotors (that is, blades, main shafts, yaw mechanisms, pitch mechanisms, etc.), speed increasers, generators, control cabinets, inverters, brakes, yaw mechanisms, and pitch mechanisms. The above components will generate a large amount of accumulated heat during operation, which will cause the cabin temperature to rise, affecting the normal operation and service life of each component. Therefore, it is necessary to dissipate heat inside the chassis of the wind power generation equipment.
[0003] According to a circulating cooling device for wind power generation disclosed in the above application (Announcement No.: CN113048028B), the high-speed wind flow at high altitude can be fully utilized to dissipate the heat inside the cabin, and the hot air inside the cabin can be ejected to prevent heat accumulation in the cabin, thereby improving the reliability of cabin heat dissipation, ensuring the stability of the working conditions of its internal functional equipment, and extending the service life of the functional equipment.
[0004] However, during the actual use of the above-mentioned equipment, although the high-speed airflow around the fan takes away the heat at the top, when the air inlet at the bottom takes in air under the action of atmospheric pressure, the colder air lacks sufficient guiding structure. When negative pressure is formed inside the machine body, the cold air flow can easily form vortices, which not only affects the smooth discharge of heat flow in the machine body, but also reduces the filling of the internal space of the machine body by the cold airflow, thereby reducing the overall cooling effect of the machine body. In view of this, we propose a circulating cooling device for wind power generation. Summary of the invention

When the main guide plate and the auxiliary guide plate rotate, they are affected by the magnetic force of the magnetic strip, so that the magnetic sheet will be attracted by the magnetic strip and cause the small arc plate to make a small deflection in the clockwise direction with the fixed rod as the rotation center.
[0016] Compared with the prior art, the present invention provides a circulating cooling device for wind power generation, which has the following beneficial effects: 1. The circulating cooling device for wind power generation is provided with an air intake guide assembly. The external airflow flows through the main guide plate at the same time, and is affected by the arc-shaped part at the bottom thereof to flow toward the air inlet along the side of the main guide plate. Due to the influence of wind force, the main guide plate deflects counterclockwise with the transmission rod as the rotation center, so that the external cold air flow can be more evenly diffused inside the machine body. While the main guide plate rotates, the auxiliary guide plate can continue to guide the external cold air flow toward the air inlet, so as to continuously reduce the temperature inside the machine body, cooperate with the discharge of hot air in the heat dissipation port, realize continuous circulation cooling inside the machine body, and ensure the normal and efficient use of the wind power generation equipment.
[0017] 2. The circulating cooling device for wind power generation is provided with an auxiliary swing component. The airflow in the external environment drives the turntable to rotate through the wind cup, and cooperates with the half gear and the gear rod to cause the U-shaped frame to perform a small reciprocating motion in the horizontal direction, so as to drive the rotating sleeve and the transmission rod to swing back and forth, thereby driving the main guide plate and the auxiliary guide plate to swing back and forth left and right, so as to actively change the flow direction of the airflow entering the body from the air inlet, thereby causing the cold air flow in the external environment to fill the internal cavity of the body faster, so as to ensure the heat dissipation effect of the electrical equipment in the body.
[0018] 3. The circulating cooling device for wind power generation is provided with a toggle assembly. During the process of the U-shaped frame performing a small reciprocating motion in the horizontal direction, the tooth pattern has the same reciprocating swinging inertia for the transmission gear and the gear ring, and then under the influence of the elastic sheet and the arc-shaped slider, it will also perform inertial motion during the rotation process, thereby increasing the deflection angle of the transmission rod driving the main guide plate to perform reciprocating swing, so as to promote the diffusion range of cold air from the external environment into the machine body, and ensure the cooling effect of the electrical equipment in the machine body.
[0019] 4. The circulating cooling device for wind power generation is provided with a spoiler assembly. When the main guide plate and the auxiliary guide plate rotate, they are affected by the magnetic force of the magnetic strip. Since the distances between the magnetic sheets arranged on the sides of the multiple groups of small arc plates and the magnetic strip are different, the deflection angles of the multiple groups of small arc plates are slightly different. As a result, when the main guide plate rotates and guides, the small arc plate cooperates with the V-shaped convex strips arranged on the side to produce an approximately disordered spoiler effect on the airflow entering the body, thereby improving the heat exchange efficiency of the colder air in the body and ensuring the working efficiency of the wind power generation equipment.

[0022] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: a circulating cooling device for wind power generation, comprising a body 1, a wind wheel 2 is arranged at one end of the body 1, a wind collecting cover 3 is fixedly installed on the top of the body 1, a wind collecting cavity 31 is opened on the inner wall of the wind collecting cover 3, a heat dissipation port 32 is opened on the bottom inner wall of the wind collecting cavity 31, an air intake guide component 4 for guiding and diffusing the cold air input into the internal space of the body 1 is arranged at the bottom of the body 1, and the air intake guide component 4 includes an air inlet 41, a rotating sleeve 42, a transmission rod 43, a main guide plate 44, a scroll spring 45, an auxiliary guide plate 46, a rotating rod 47, an arc plate 48, a coil spring 49 and an arc guide groove 410.
[0023] In one embodiment of the present invention, an air inlet 41 is provided on the bottom inner wall of the machine body 1, a rotating sleeve 42 is rotatably installed on the inner wall of the air inlet 41, a transmission rod 43 is movably installed on the inner wall of the rotating sleeve 42, the transmission rod 43 passes through and is fixedly installed with a main guide plate 44, a volute spring 45 is sleeved on the arc-shaped outer wall of the rotating sleeve 42, an auxiliary guide plate 46 is provided inside the air inlet 41, a rotating rod 47 is rotatably installed on the top inner wall of the main guide plate 44, the rotating rod 47 passes through and is fixedly installed with an arc-shaped plate 48, a coil spring 49 is sleeved on the arc-shaped outer wall of the rotating rod 47, and an arc-shaped guide groove 410 is provided at the center of the arc-shaped plate 48.
[0024] For further information, please refer to the attached manual. Figure 1-Figure 2 The wind collecting hood 3 is wide at one end close to the wind wheel 2 and narrow at the other end away from the wind wheel 2, and the interior of the wind collecting chamber 31 is arc-shaped to avoid affecting the airflow entering the wind collecting hood 3. Since the airflow channel in the wind collecting chamber 31 becomes narrower, the airflow velocity in the wind collecting hood 3 set in the high altitude becomes faster, thereby forming a low pressure inside the wind collecting chamber 31. Under the action of atmospheric pressure, the hot air in the body 1 is sucked into the wind collecting chamber 31 from the heat dissipation port 32, and flows out from the right end following the airflow in the wind collecting chamber 31, thereby taking away the heat in the body 1. There is no need to add additional equipment such as a motor to provide power, thereby ensuring the continuous heat dissipation effect in the body 1. At the same time, an arc-shaped baffle is provided on the top of the heat dissipation port 32 to avoid the backflow of the airflow in the wind collecting chamber 31, and also to prevent the hot air from condensing into water droplets after being cooled and flowing back into the body 1, causing short circuit and damage to the electrical equipment in the body 1.
[0025] Please refer to the instruction manual Figure 2-Figure 5In the embodiment of the present invention, the heat dissipation port 32 is arranged on the top left side of the body 1, and the air inlet 41 is opened at the bottom of the body 1 near the right end, so that when the internal airflow of the body 1 realizes heat dissipation, the colder gas replenished in the external environment can more completely fill the internal cavity of the body 1, so as to improve the overall heat dissipation efficiency of the body 1. At the same time, a rectangular limit block is arranged on the arc-shaped outer wall of the end of the transmission rod 43, and a rectangular slide groove adapted to the above-mentioned rectangular limit block is arranged on the arc-shaped inner wall of the rotating sleeve 42, so that the rotating sleeve 42 and the transmission rod 43 can only perform relative movement in the horizontal direction, and no relative rotation occurs. In addition, the two ends of the volute spring 45 The ends are respectively fixedly connected to the inner wall of the body 1 and the arc-shaped outer wall of the rotating sleeve 42, so that the rotating sleeve 42 always has a tendency to rotate in the opposite direction to achieve reset when rotating. Furthermore, the bottom of the main guide plate 44 is arranged in an arc shape bent toward the side of the wind wheel 2, and in the initial state, the main guide plate 44 is in a vertical state. When the airflow flows along the outer surface of the body 1 at high altitude, it is guided by the arc-shaped part at the bottom of the main guide plate 44, so that the airflow is easier to enter the interior of the body 1 through the air inlet 41 along the surface of the main guide plate 44, thereby replenishing the air inside the body 1. At the same time, the colder air in the external environment can also cool the electrical equipment in the body 1.
[0026] At the same time, the auxiliary guide plate 46 is configured in the same manner as the main guide plate 44, and the main guide plate 44 and the auxiliary guide plate 46 are respectively configured on the left and right sides of the vertical central axis of the air inlet 41, and at the same time, the bottom curved portions of the main guide plate 44 and the auxiliary guide plate 46 are oriented in the same direction, so that when the main guide plate 44 is deflected by a large wind force and the auxiliary guide plate 46 can also ensure the normal air intake supplement effect of the air inlet 41. In addition, a hinged ear is provided on the top of the main guide plate 44, and the top surface of the main guide plate 44 is configured to be an arc that matches the bottom end of the arc plate 48, so that the main guide plate 44 and the arc plate 48 can both ensure relative rotation and make the gap at the connection between the two smaller, thereby reducing airflow. In order to solve the leakage problem when flowing along the surface of the main guide plate 44, the inner wall of the hinged ear is provided with a circular hole with a diameter larger than the outer diameter of the coil spring 49, and the two ends of the coil spring 49 are respectively fixedly connected to the bottom inner wall of the circular hole and the arc-shaped outer wall of the rotating rod 47, so that under the elastic force of the coil spring 49, the rotating rod 47 always has a movement tendency to drive the arc plate 48 to rotate in the opposite direction to achieve reset. Specifically, the arc guide groove 410 is V-shaped with a narrow bottom end and a wide top end, so that the airflow moving along the main guide plate 44 and the side of the arc plate 48 can obtain a larger diffusion range when it leaves the arc plate 48, thereby better filling the interior of the body 1 to ensure a uniform heat exchange effect in the body 1.
[0027] When the external airflow flows on the outside of the body 1, the airflow enters the wind collection chamber 31 from wide to narrow, forming a high-speed airflow and generating low pressure in the wind collection chamber 31. At the same time, the external airflow flows through the main guide plate 44, and is affected by the arc-shaped part at the bottom thereof and flows toward the air inlet 41 along the side of the main guide plate 44. Due to the influence of wind force, the main guide plate 44 deflects counterclockwise with the transmission rod 43 as the rotation center, thereby changing the direction of the arc plate 48, and at the same time, it will have a tendency to rotate in the opposite direction under the influence of the elastic force of the spiral spring 45. With the setting of the arc guide groove 410, the external cold air flow can be more evenly diffused inside the body 1. While the main guide plate 44 rotates, the auxiliary guide plate 46 can continue to guide the external cold air flow toward the air inlet 41, so as to continuously reduce the temperature inside the body 1. With the discharge of hot air in the heat dissipation port 32, continuous circulation cooling in the body 1 is realized, thereby ensuring the normal and efficient use of the wind power generation equipment.
[0028] In addition, please refer to the instructions attached Figure 5-Figure 8 An auxiliary swing assembly 5 is arranged inside the machine body 1 to cause the main guide plate 44 to actively deflect itself. The auxiliary swing assembly 5 includes a half gear 51, which is rotatably mounted on the inner wall of the machine body 1, and a turntable 52 is coaxially fixedly mounted on the half gear 51. A wind cup 53 is fixedly mounted on the arc-shaped outer wall of the turntable 52. A U-shaped frame 54 is slidably mounted on the inner wall of the machine body 1, and a gear rod 55 is fixedly mounted on the outer wall of the U-shaped frame 54 close to the half gear 51. A return spring 56 is fixedly connected to the side wall of the U-shaped frame 54. A fixed cylinder 57 is fixedly mounted on the inner wall of the machine body 1, and a rotating ring 58 is rotatably mounted on the end of the fixed cylinder 57. A volute spring 2 59 is sleeved on the arc-shaped outer wall of the fixed cylinder 57, a gear ring 510 is arranged on the arc-shaped outer wall of the rotating ring 58, and a transmission gear 511 is fixedly mounted on the arc-shaped outer wall of the rotating sleeve 42.
[0029] Furthermore, a transmission cavity is provided on the inner wall of the machine body 1 to facilitate the installation of structures such as the half gear 51, the U-shaped frame 54, the gear rod 55, the return spring 56, the fixing cylinder 57, the rotating ring 58, the spiral spring 2 59, the gear ring 510 and the transmission gear 511. At the same time, the turntable 52 and the wind cup 53 are arranged in the lower external space of the machine body 1, and the number of the wind cups 53 is arranged in multiple groups, and the multiple groups of wind cups 53 are evenly distributed on the arc-shaped outer wall of the turntable 52 in a circular array, so that the airflow in the external environment can drive the turntable 52 to rotate through the wind cup 53, thereby driving the half gear 51 to rotate continuously, and the half gear 51 is meshed with the gear rod 55, so that Under the elastic force of the return spring 56, the U-shaped frame 54 performs a small reciprocating motion on the inner wall of the body 1. At the same time, the lower surface of the U-shaped frame 54 is provided with teeth that can mesh with the gear ring 510 and the transmission gear 511. Therefore, through the design of the half gear 51, the reciprocating motion of the U-shaped frame 54 drives the rotating sleeve 42 and the transmission rod 43 to swing back and forth, thereby driving the main guide plate 44 and the auxiliary guide plate 46 to swing back and forth left and right, so as to actively change the flow direction of the airflow entering the body 1 from the air inlet 41, thereby prompting the cold air flow in the external environment to fill the internal cavity of the body 1 faster, so as to ensure the heat dissipation effect of the electrical equipment in the body 1.
[0030] At the same time, the outer diameters of the gear ring 510 and the transmission gear 511 are set to be exactly the same, so that the transmission efficiency of the gear ring 510 and the transmission gear 511 for the transmission rod 43 is completely consistent when they are driven by the U-shaped frame 54. In addition, a through hole with a diameter matching the outer diameter of the transmission rod 43 is opened on the arc-shaped outer wall of the rotating ring 58, and a rectangular slide groove matching the rectangular limit block set on the arc-shaped outer surface of the transmission rod 43 is opened on the arc-shaped inner surface of the through hole, so that the transmission rod 43 drives the rotating ring 58 to rotate, and at the same time, the other end of the transmission rod 43 drives the rotating sleeve 42 and the transmission gear 511 to rotate in the same direction and at the same speed. Furthermore, the two ends of the spiral spring 59 are fixedly connected to the inner wall of the body 1 and the side wall of the rotating ring 58 respectively, so that the rotating ring 58 always has a movement tendency of reverse rotation to achieve reset when rotating.
[0031] Please refer to the instruction manual Figure 6-Figure 7 In an embodiment of the present invention, a toggle assembly 6 that can enhance the reciprocating swinging effect of the main guide plate 44 is provided on the arc-shaped outer wall of the rotating ring 58. The toggle assembly 6 includes an arc-shaped groove 61, which is opened on the arc-shaped outer wall of the rotating ring 58. An arc-shaped guide rod 62 is fixedly installed on the inner wall of the arc-shaped groove 61. An arc-shaped slider 63 is penetrated and slidably installed on the arc-shaped guide rod 62. An elastic sheet 64 is fixedly connected between the side wall of the arc-shaped slider 63 and the inner wall of the end of the arc-shaped groove 61. A avoidance ball 65 is fixedly installed on the arc-shaped outer wall of one end of the transmission rod 43 close to the fixed cylinder 57, and a convex ball 66 is fixedly installed on the arc-shaped inner wall of the fixed cylinder 57.
[0032] In an embodiment of the present invention, the number of arc grooves 61 is multiple, and the multiple arc grooves 61 are evenly distributed in a circular array on the arc outer surface of the rotating ring 58. At the same time, the number of elastic sheets 64 is two, and the two sets of elastic sheets 64 are mirror-imaged on the left and right end surfaces of the arc slider 63, and the inner wall of the arc slider 63 is provided with a through hole adapted to the arc guide rod 62 to facilitate the arc slider 63 to move along the inner surface of the arc groove 61. Specifically, the outer surface of the side of the arc slider 63 away from the rotating ring 58 is fixedly connected to the arc inner surface of the gear ring 510. Further, the transmission gear 511 is configured to be the same as the rotating ring 58 and the gear ring 510, so that the U-shaped frame 54 can move in an arc shape. During the small reciprocating motion in the horizontal direction, the tooth pattern has the same reciprocating swinging inertia for the transmission gear 511 and the gear ring 510, and then in the process of rotation under the influence of the elastic sheet 64 and the arc-shaped slider 63, it will also perform inertial motion, thereby increasing the deflection angle of the transmission rod 43 in driving the main guide plate 44 to swing back and forth, so as to promote the diffusion range of the cold air in the external environment into the body 1, and ensure the cooling effect of the electrical equipment in the body 1. At the same time, the convex ball 66 and the avoidance ball 65 are arranged in the same plane, so that when the transmission rod 43 rotates, it is affected by the convex ball 66 and prompts the transmission rod 43 to move in the horizontal direction, so as to increase the wind guide operation range of the main guide plate 44. Example
[0033] Please refer to the instruction manual Figure 9-10 In an embodiment of the present invention, a spoiler assembly 7 that can guide the cold air in an approximately disorderly manner is provided at the top of the main guide plate 44. The spoiler assembly 7 includes a fixing rod 71, which is fixedly installed at the top of the main guide plate 44. The fixing rod 71 passes through and rotatably installs a small arc plate 72. A cylindrical hole is opened on the side wall of the small arc plate 72, and a spiral spring three 73 is arranged in the cylindrical hole. A V-shaped convex strip 74 is fixedly installed on the side wall of the small arc plate 72, and a magnetic sheet 75 is fixedly installed on the outer wall of the small arc plate 72 away from the V-shaped convex strip 74. A magnetic strip 76 is fixedly installed on the top side wall of the auxiliary guide plate 46 close to the main guide plate 44.
[0034] It is worth noting that there are multiple groups of small arc plates 72, and the multiple groups of small arc plates 72 are evenly distributed in a linear array on the top of the main guide plate 44. At the same time, the two ends of the spiral spring three 73 are respectively connected to the bottom inner wall of the cylindrical hole and the arc-shaped outer wall of the fixing rod 71, so that the small arc plate 72 can rotate with the fixing rod 71 as the rotation axis. In addition, the sharp section of the V-shaped convex strip 74 is set in a direction so that the colder air flow flowing along the surface of the main guide plate 44 is affected by the V-shaped convex strip 74 and dispersed to both sides. Furthermore, the magnetism of the magnetic sheet 75 is opposite to that of the magnetic strip 76, so that the magnetic sheet 75 and the magnetic strip 76 have a magnetic force that attracts each other. When the main guide plate 44 and the auxiliary guide plate 46 are rotating, they are affected by the magnetic force of the magnetic strip 76, so that the magnetic sheet 75 is attracted by the magnetic strip 76 and prompts the small arc plate 72 to slightly deflect in the clockwise direction with the fixed rod 71 as the rotation center. Since the distances between the magnetic sheets 75 and the magnetic strip 76 arranged on the sides of the multiple groups of small arc plates 72 are different, the deflection angles of the multiple groups of small arc plates 72 are slightly different. As a result, when the main guide plate 44 is rotating and guiding, the small arc plate 72 cooperates with the V-shaped convex strips 74 arranged on the side thereof to produce an approximately disordered turbulence effect on the airflow entering the body 1, thereby improving the heat exchange efficiency of the colder air in the body 1 and ensuring the working efficiency of the wind power generation equipment.
[0035] In the present invention, when in use, when the wind turbine is operating, the wind wheel 2 itself rotates continuously. Since the body 1 of the wind turbine is arranged at a high altitude, when the high-altitude fast airflow enters the wind collecting chamber 31, the airflow channel in the wind collecting chamber 31 becomes narrower from wide, so that the airflow velocity in the wind collecting cover 3 arranged at a high altitude becomes faster, thereby forming a low pressure inside the wind collecting chamber 31. Under the action of atmospheric pressure, the hot air in the body 1 is sucked into the wind collecting chamber 31 from the heat dissipation port 32, and flows out from the right end along with the airflow in the wind collecting chamber 31, thereby taking away the heat in the body 1. At the same time, the airflow in the external environment can drive the turntable 52 to rotate through the wind cup 53 The U-shaped frame 54 performs a small reciprocating motion on the inner wall of the machine body 1, thereby driving the rotating sleeve 42 and the transmission rod 43 to swing back and forth, thereby driving the main guide plate 44 and the auxiliary guide plate 46 to swing back and forth, so as to actively change the flow direction of the airflow entering the machine body 1 from the air inlet 41, thereby causing the cold air flow in the external environment to fill the internal cavity of the machine body 1 faster, so as to continuously reduce the temperature in the machine body 1, cooperate with the discharge of hot air in the heat dissipation port 32, realize continuous circulation cooling in the machine body 1, and ensure the normal and efficient use of the wind power generation equipment.
[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
