Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation equipment, and in particular to an energy storage and heat dissipation mechanism for a wind power generator set. Background Art

[0002] A wind turbine is a system that converts wind energy into electrical energy. It mainly uses wind energy to drive the blades to rotate, converting wind energy into mechanical energy. Then, it generates electricity through a speed-increasing transmission system and a generator to convert mechanical energy into electrical energy. After being converted into electrical energy, the electrical energy is stored in a battery energy storage device and released in a short time.

[0003] However, the existing energy storage devices of wind turbines have some defects, such as:

[0004] Existing energy storage devices only use a fan to blow air inside the device to cool it down when cooling and dissipating heat. However, due to the close distance between multiple battery packs, the airflow generated by the fan cannot flow between the multiple battery packs, ultimately resulting in poor cooling effect.

[0005] Therefore, the present invention provides an energy storage and heat dissipation mechanism for a wind turbine generator set to solve the above problems. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an energy storage and heat dissipation mechanism for a wind turbine generator set to solve the problem that the airflow in the above energy storage device cannot flow between multiple battery packs, resulting in poor cooling effect.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] An energy storage and heat dissipation mechanism for a wind turbine generator set includes a housing, wherein the upper and lower sides of the housing are both provided with air holes in a rectangular array, a rectangular array of hollow support columns is formed within the housing, the hollow support columns are connected to the upper and lower air holes, a fixed energy storage battery rack is fixed in a linear array between two rows of hollow support columns, and a sliding energy storage battery rack is slid in a linear array between the two rows of hollow support columns, wherein the fixed energy storage battery rack and the sliding energy storage battery rack are arranged in an intersecting manner;

[0009] A second fan is rotatably connected to the rectangular array in the lower end of the housing. The second fan is located directly below the air hole and is installed at an angle.

[0010] Air ducts are arranged in a linear array at the front and rear ends of the upper and lower sides of the housing, the fixed energy storage battery rack and the sliding energy storage battery rack are located between the four exhaust ducts, and the second fan is located between the air ducts and the air holes;

[0011] Through the above technical solution, when the second fan is powered on, it can generate airflow, which passes through the upper air holes, the hollow support column and the lower air holes, and the heat in the shell is transferred to the hollow support column. The airflow removes the heat from the hollow support column, thereby removing the heat in the shell and performing primary cooling.

[0012] The airflow from the second fan can be blown directly to the outside, or the second fan can be rotated to blow the airflow toward the air duct. After the airflow enters the interior of the housing, it can directly ventilate and cool the interior of the housing, that is, cool the front of the fixed energy storage battery rack and the sliding energy storage battery rack, thereby performing secondary cooling.

[0013] The sliding energy storage battery rack can be moved forward to offset the fixed energy storage battery rack and the sliding energy storage battery rack front to back, so that air flow channels are formed in front and behind the fixed energy storage battery rack and the sliding energy storage battery rack, and the front and rear of the fixed energy storage battery rack and the sliding energy storage battery rack can be cooled, thereby achieving three-stage cooling.

[0014] Preferably, the upper side of the housing is provided with a second cavity and two first cavities, and the second cavity is located between the two first cavities;

[0015] The air holes are connected to the second cavity, and the upper linear array of the second cavity is provided with air inlets;

[0016] The air duct is connected to the first cavity, an air outlet is provided on the side of the first cavity and a filter is fixed in the air outlet;

[0017] Through the above technical solution, the stomata and airways can be isolated from the outside world, preventing debris such as leaves from falling into the stomata and airways.

[0018] Preferably, a layered plate is fixed inside the lower end of the shell, and the layered plate divides the interior of the lower end of the shell into a third cavity and a fourth cavity. An exhaust port is provided on the side of the fourth cavity, and the exhaust port of the fourth cavity and the air outlet of the first cavity are located on the same side of the shell;

[0019] The third cavity is located above the fourth cavity, the air passage passes through the third cavity and the layered plate and then flows into the fourth cavity, the air holes are connected to the third cavity, the layered plate is provided with arc holes in a rectangular array, the arc holes are located directly below the air holes, and the second fan is located directly below the arc holes;

[0020] A second electric push rod is fixed to the side of the housing, and a side sliding wall is fixed to the output end of the second electric push rod. The side sliding wall is movably inserted into the end of the housing up and down, and the side sliding wall alternately blocks the air outlet of the first cavity and the exhaust port of the fourth cavity when moving up and down. When the side sliding wall moves up and down, it drives the second fan to rotate through the transmission assembly;

[0021] Through the above technical solution, when the second electric push rod pushes the side sliding wall to move upward, it can block the air outlet of the first cavity and open the exhaust port of the fourth cavity, so that the air flow can be discharged directly from the exhaust port of the fourth cavity during primary cooling;

[0022] When the second electric push rod pushes the side sliding wall to move downward, it can block the exhaust port of the fourth cavity and open the air outlet of the first cavity, so that the air flow can be forced to pass through the inside of the shell during the second and third stage cooling, and the air flow is forced to be discharged from the air outlet of the first cavity;

[0023] When the side sliding wall moves up and down, the second fan is driven to rotate by the transmission assembly to adjust the direction of the second fan. In the primary cooling mode, the second fan can be directed toward the exhaust port of the fourth cavity. In the secondary cooling mode, the second fan can be directed toward the air duct.

[0024] In summary, the direction of the airflow can be comprehensively controlled by simultaneously controlling the direction of the second fan, the opening and closing of the air outlet of the first cavity, and the opening and closing of the exhaust port of the fourth cavity.

[0025] Preferably, the transmission assembly includes a transmission slide, a toothed plate, a gear, a rotating shaft, a spring and a push rod. The rotating shaft rotates in a rectangular array through the layered plate. The lower end of the rotating shaft is fixed with the second fan. The rotation center of the rotating shaft is on the same straight line as the center of the arc hole. A gear is fixedly sleeved outside the rotating shaft.

[0026] The transmission slide is laterally movable and inserted into the fourth cavity. The end of the transmission slide extends out of the exhaust port of the fourth cavity. The end of the transmission slide is provided with an inclined surface, and the inclined surface is located directly below the side sliding wall. A toothed plate is fixed on the inner side of the transmission slide, and the toothed plate is meshed with the gear teeth. A push rod is fixed to the end of the transmission slide, and the push rod moves through the lower side protrusion of the fourth cavity. A spring is fixed between the transmission slide and the lower side protrusion of the fourth cavity, and the push rod is located inside the spring.

[0027] Through the above technical solution, the up and down movement of the side sliding wall and the expansion and contraction of the spring can be used to control the lateral circular movement of the transmission slide, and the power transmission of the tooth plate and the gear can be used to drive the rotating shaft to rotate forward and backward, thereby controlling the forward and reverse rotation of the second fan to adjust the direction of the second fan.

[0028] Preferably, a control switch is fixed on the lower side of the fourth cavity, the control switch is located within the moving range of the ejector rod, and the input end of the control switch is electrically connected to the mains power supply;

[0029] Two rows of first fans are fixed in the fourth cavity. The first fans are located directly below the air duct. The first fans are tilted and the air outlet ends are obliquely upward toward the air duct. The output end of the control switch is electrically connected to the first fans.

[0030] With the above technical solution, when the control switch of the top rod is turned on, the first fan can be powered on to work together with the second fan to generate airflow, thereby increasing the wind force. The first fan is installed at an angle and faces the airway, thereby accurately guiding the airflow.

[0031] Moreover, the action of opening and closing the control switch of the top rod is synchronized with the turning action of the second fan, so that the three actions of adjusting the direction of the second fan, opening and closing the air outlet of the first cavity, and opening and closing the exhaust port of the fourth cavity are synchronized with the power-on operation of the first fan.

[0032] Preferably, a high-density filter cotton is fixed in the fourth cavity, and the high-density filter cotton is located between the first fan and the second fan;

[0033] Through the above technical solution, the high-density filter cotton filters the airflow and improves the purity of the airflow. The high-density filter cotton will hinder the flow of airflow to a certain extent. Therefore, the first fan is set to ensure that the airflow can pass through the high-density filter cotton with great force.

[0034] Preferably, a first electric push rod is fixed to the lower side of the housing, and an output end of the first electric push rod is fixed to the lower end of the sliding energy storage battery rack;

[0035] Through the above technical solution, the first electric push rod drives the sliding energy storage battery rack to move forward and backward.

[0036] Preferably, oblique-end connecting tubes are fixed in a rectangular array at the front and rear ends of the upper and lower sides of the interior of the housing. The openings of the oblique-end connecting tubes are arranged at an angle. The oblique-end connecting tubes are connected to the air ducts located in the front and rear of the sliding energy storage battery rack. Inclined sealing plates are fixed to the four corners of the upper and lower ends of the sliding energy storage battery rack. When the sliding energy storage battery rack moves forward, the front inclined sealing plate blocks the front oblique-end connecting tubes forward. When the sliding energy storage battery rack moves backward, the rear inclined sealing plate blocks the rear oblique-end connecting tubes backward.

[0037] With the above technical solution, after the sliding energy storage battery rack moves backward, the oblique-ended connecting pipe in front of it needs to pass through the airflow. In this case, the oblique-ended connecting pipe in front is unobstructed and can ventilate normally, while the oblique-ended connecting pipe in the rear is blocked by the inclined sealing plate, ensuring that the airflow can only flow through the front of the sliding energy storage battery rack.

[0038] Similarly, after the sliding energy storage battery rack moves forward, the oblique-end connecting pipe at the rear needs to pass airflow. In this case, the oblique-end connecting pipe at the rear is not blocked and can ventilate normally, while the oblique-end connecting pipe at the front is blocked by the inclined sealing plate, ensuring that the airflow can only flow through the rear of the sliding energy storage battery rack.

[0039] The beneficial effects of the present invention are:

[0040] 1. During primary cooling, the heat in the housing is transferred to the hollow support columns. When the air flows through the hollow support columns, it removes the heat from the hollow support columns, thereby removing the heat from the housing. The hollow support columns are located between the adjacent fixed energy storage battery racks and the sliding energy storage battery racks, allowing the air flow to flow through the fixed energy storage battery racks and the sliding energy storage battery racks to perform primary cooling. That is, the air flow does not directly enter the housing, which ensures the cleanliness of the housing and can be used for regular temperature maintenance.

[0041] 2. During secondary cooling, the second fan blows the airflow toward the airway. After the airflow enters the interior of the housing, it can directly ventilate and cool the interior of the housing. During this process, the high-density filter cotton filters the airflow to improve the purity of the airflow. The first fan is turned on to increase the wind force and cool the front of the fixed energy storage battery rack and the sliding energy storage battery rack. In other words, the interior of the housing is directly cooled while ensuring the cleanliness of the housing. It can be used for routine cooling.

[0042] 3. During the third-stage cooling process, the sliding energy storage battery rack moves forward, causing the fixed energy storage battery rack and the sliding energy storage battery rack to be offset front to back, thereby forming airflow channels in front and behind the fixed energy storage battery rack and the sliding energy storage battery rack. This allows airflow to flow between the fixed energy storage battery rack and the sliding energy storage battery rack, thereby cooling the front and back of both the fixed energy storage battery rack and the sliding energy storage battery rack. In other words, by increasing the contact area between the airflow and the fixed energy storage battery rack and the sliding energy storage battery rack, the interior of the housing can be efficiently and urgently cooled.

[0043] In summary, this device can selectively perform primary cooling, secondary cooling, and tertiary cooling on the inside of the shell to cope with different conditions inside the shell. It performs primary insulation when the temperature inside the shell is not high, performs conventional cooling when the temperature inside the shell initially rises, and performs efficient cooling when the temperature inside the shell continues to rise. A variety of selection methods are used to cope with cooling in different situations, and the cooling effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] See attached Figure 3 Two rows of hollow support columns 12 are fixed in a rectangular array in the housing 3. The upper ends of the hollow support columns 12 are connected to the air holes 11 on the upper side of the housing 3, and the lower ends are connected to the air holes 11 on the lower side of the housing 3. Figure 1 , Attachment Figure 3 and attached Figure 5 , a fixed energy storage battery rack 7 is fixed in a linear array between the two rows of hollow support columns 12, and a sliding energy storage battery rack 5 is slid in a linear array between the two rows of hollow support columns 12.

The fixed energy storage battery rack 7 and the sliding energy storage battery rack 5 are cross-distributed. For details of the specific arrangement, please see the attached Figure 1 and attached Figure 8 ;

[0057] A second fan 23 is rotatably connected to a rectangular array within the lower end of the housing 3. The input end of the second fan 23 is electrically connected to the mains power supply. The number of the second fans 23 is equal to the number of the hollow support columns 12, and the second fans 23 are located directly below the arc-shaped hole 25. The rotation center of the second fan 23 and the center of the arc-shaped hole 25 are on the same vertical line. The second fans 23 are installed at an angle so that the air inlet end of the second fan 23 faces the arc-shaped hole 25 and the air outlet end of the second fan 23 is obliquely downward.

[0058] Air passages 4 are arranged in a linear array at the front and rear ends of the upper and lower sides of the housing 3. The air passages 4 located in the upper side of the housing 3 are connected to the first cavity 9. The air passages 4 located in the lower side of the housing 3 pass through the third cavity 17 and the layer plate 20 and then flow into the fourth cavity 18. The second fan 23 is located between the air passages 4 and the arc-shaped hole 25.

[0059] Please refer to the attached Figure 1 and attached Figure 6It can be seen that the air ducts 4 are arranged in a row at the front end of the upper side of the shell 3, with four air ducts 4, a row at the rear end of the upper side of the shell 3, a row at the front end of the lower side of the shell 3, with four air ducts 4, and a row at the rear end of the lower side of the shell 3, with two air ducts 4, that is, there are two air ducts 4 in front of the two fixed energy storage battery racks 7 and no air ducts 4 in the rear, and there are two air ducts 4 in front and behind the two sliding energy storage battery racks 5.

[0060] In this embodiment, a second electric push rod 26 is fixed to the side of the housing 3, the input end of the second electric push rod 26 is electrically connected to the mains power supply, and the output end of the second electric push rod 26 is fixed to a side sliding wall 1, which is movable up and down and inserted into the end of the housing 3. When the side sliding wall 1 moves up and down, it alternately blocks the air outlet of the first cavity 9 and the exhaust port of the fourth cavity 18. When the side sliding wall 1 moves up and down, it drives the second fan 23 to rotate through the transmission assembly;

[0061] The transmission assembly includes a transmission carriage 2, a toothed plate 21, a gear 22, a rotating shaft 24, a spring 27, and a push rod 28. The rotating shafts 24 rotate in a rectangular array through the layered plate 20. The number of rotating shafts 24 is equal to the number of hollow support columns 12 and is located directly below the hollow support columns 12. The lower end of the rotating shaft 24 is fixed with the second fan 23. The rotation center of the rotating shaft 24 is on the same straight line as the center of the arc hole 25. The rotating shaft 24 is fixed with a gear 22.

[0062] The transmission slide 2 is laterally movable and inserted into the fourth cavity 18. The end of the transmission slide 2 extends out of the exhaust port of the fourth cavity 18. The end of the transmission slide 2 is provided with an inclined surface, and the inclined surface is located directly below the side sliding wall 1. A toothed plate 21 is fixed to the inner side of the transmission slide 2. The number of toothed plates 21 is equal to the number of gears 22. The teeth of the toothed plates 21 and the gears 22 are meshed. A push rod 28 is fixed to the end of the transmission slide 2. The push rod 28 moves through the lower side protrusion of the fourth cavity 18. A spring 27 is fixed between the transmission slide 2 and the lower side protrusion of the fourth cavity 18, and the push rod 28 is located inside the spring 27.

[0063] The transmission assembly works as follows: when the side sliding wall 1 moves downward, it slides on the inclined surface of the transmission slide 2, pushing the transmission slide 2 to the right. The spring 27 is compressed, and the transmission slide 2 drives the gear plate 21 to move to the right. The gear plate 21 drives the gear 22 to rotate. The gear 22 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the second fan 23 to rotate, thereby adjusting the direction of the second fan 23.

[0064] When the side sliding wall 1 moves upward, it leaves the transmission slide 2. At this time, the spring 27 stretches and pushes the transmission slide 2 back to the left. At this time, the gear plate 21 drives the gear 22 to rotate in the opposite direction, and the gear 22 drives the rotating shaft 24 to rotate in the opposite direction. The rotating shaft 24 drives the second fan 23 to rotate in the opposite direction, so that the second fan 23 returns to its original direction.

[0065] In this embodiment, see the attached Figure 3 and attached Figure 5 A control switch 15 is fixed to the lower side of the fourth cavity 18. The control switch 15 is located within the moving range of the ejector rod 28. The input end of the control switch 15 is electrically connected to the mains power supply.

[0066] Two rows of first fans 19 are fixed in the fourth cavity 18. The first fans 19 are located directly below the air duct 4. The first fans 19 are tilted and the air outlet ends are obliquely upward toward the air duct 4. The output end of the control switch 15 is electrically connected to the first fans 19. High-density filter cotton 16 is fixed in the fourth cavity 18. The high-density filter cotton 16 is located between the first fan 19 and the second fan 23.

[0067] In this embodiment, see the attached Figure 1 , Attachment Figure 3 and attached Figure 5 , the front and rear ends of the upper and lower sides of the interior of the shell 3 are fixed with oblique-end connecting tubes 6 in a rectangular array. In this embodiment, the number of oblique-end connecting tubes 6 is 8, that is, there are 2 groups of oblique-end connecting tubes 6 and 4 in each group. The openings of the oblique-end connecting tubes 6 are arranged obliquely, and the oblique-end connecting tubes 6 are connected to the air ducts 4 located in the front and rear of the sliding energy storage battery rack 5. The sliding energy storage battery rack 5 is located between the 4 oblique-end connecting tubes 6 in each group. An inclined sealing plate 13 is fixed to the four corners of the upper and lower ends of each sliding energy storage battery rack 5. When the sliding energy storage battery rack 5 moves forward, the front inclined sealing plate 13 blocks the front oblique-end connecting tube 6 forward. When the sliding energy storage battery rack 5 moves backward, the rear inclined sealing plate 13 blocks the rear oblique-end connecting tube 6 backward.

[0068] The working principle of this device is:

[0069] During primary cooling, only the second fan 23 is powered on to generate airflow. At this time, the second fan 23 faces the exhaust port of the fourth cavity 18. The airflow passes through the air inlet of the second cavity 10, the second cavity 10, the air hole 11 on the lower side of the second cavity 10, the interior of the hollow support column 12, the air hole 11 on the upper side of the third cavity 17, the third cavity 17, the arc-shaped hole 25, the fourth cavity 18 and the exhaust port of the fourth cavity 18 in sequence. When the airflow passes through the interior of the hollow support column 12, the heat inside the outer shell 3 is transferred to the airflow through the hollow support column 12, thereby taking away the heat inside the outer shell 3 and cooling the interior of the outer shell 3. Moreover, the hollow support column 12 is sandwiched between the fixed energy storage battery rack 7 and the sliding energy storage battery rack 5, and can absorb the heat of the fixed energy storage battery rack 7 and the sliding energy storage battery rack 5 to a greater extent.

[0070] During the second-stage cooling, the second electric push rod 26 is energized to push the side sliding wall 1 downward. At this time, the air outlet of the first cavity 9 is opened, and the exhaust port of the fourth cavity 18 is closed. When the side sliding wall 1 moves downward, the transmission assembly drives the second fan 23 to rotate, so that the second fan 23 faces the high-density filter cotton 16. At the same time, the control switch 15 is turned on, and the first fan 19 is turned on. The air flow passes through the air inlet of the second cavity 10, the second cavity 10, the air hole 11 on the lower side of the second cavity 10, the interior of the hollow support column 12, the air hole 11 on the upper side of the third cavity 17, the third cavity 17, the arc hole 25, the fourth cavity 18, the high-density filter cotton 16, the first fan 10, the air duct 4 in the lower end of the shell 3, the interior of the shell 3, the air duct 4 in the upper end of the shell 3, the first cavity 9 and the air outlet of the first cavity 9 to directly carry out the heat in the shell 3;

[0071] During the third stage of cooling, the first electric push rod 14 is energized to drive the sliding energy storage battery rack 5 to move forward, so that the rear of the sliding energy storage battery rack 5 is exposed, and the oblique end connecting pipe 6 in front of the sliding energy storage battery rack 5 is blocked by the inclined sealing plate 13. The inclined sealing plate 13 behind the sliding energy storage battery rack 5 leaves the oblique end connecting pipe 6, and the air flow still passes through the air inlet of the second cavity 10, the second cavity 10, the air hole 11 on the lower side of the second cavity 10, and the inner part of the hollow support column 12. The air duct 4 in the lower end of the outer shell 3, the inside of the outer shell 3, the air duct 4 in the upper end of the outer shell 3, the first cavity 9 and the air outlet of the first cavity 9, but when the air flow passes through the inside of the outer shell 3, part of the air flow passes through the rear of the sliding energy storage battery rack 5, and the other part of the air flow passes through the front of the fixed energy storage battery rack 7, and the air flow carries out the heat in the outer shell 3.
