Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic wind power boxes, and in particular to a photovoltaic wind power box with self-regulating ventilation. Background Art

[0002] A photovoltaic wind turbine box is an electrical device used in photovoltaic and wind power generation systems, primarily responsible for distributing and managing electrical energy while also providing protection and control functions. Various electrical components are installed within the box, which generate significant heat during operation. To ensure safe operation, ventilation holes are typically installed within the box, along with fans positioned near heat-generating components to cool the box.

[0003] During the operation of the photovoltaic wind turbine box, the fan rotates to keep the air inside the box in a flowing state, and the air inside the box is exchanged with the outside air in a timely manner through the vents. However, the air outlets of existing fans are mostly fixed, and their installation position and direction are determined when the equipment is manufactured. This means that the direction and coverage of the airflow are fixed. If the electrical components in the equipment box are unevenly distributed or the electrical components form dead corners and accumulate a large amount of heat, the fixed air outlets cannot effectively discharge the heat from all hot spots, and thus some electrical components cannot be adequately cooled and overheat, affecting their performance and lifespan.

DETAILED DESCRIPTION

[0021] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] Example 1: A photovoltaic wind power box with self-regulating ventilation, such as Figures 1-6As shown, it includes a box body 1, the box body 1 is fixedly connected to and connected with a number of symmetrically distributed ventilation pipes 2, a number of exhaust ports are arranged on the upper part of the box body 1, the box body 1 is fixedly connected with a first fixed frame 3 with the same number as the ventilation pipes 2, the first fixed frame 3 is provided with a plurality of wind shields 4 distributed at intervals, a fan 5 is installed in the ventilation pipe 2, the box body 1 is rotatably connected with the same number of exhaust pipes 6 as the ventilation pipes 2, the air outlet of the fan 5 is connected with the exhaust pipe 6, and a number of circular holes connected with the box body 1 are provided on the circumference of the exhaust pipe 6, the box body 1 is provided with the same number of air cavities 101 as the ventilation pipes 2, the air cavities 101 are connected with the box body 1 and the adjacent ventilation pipes 2, a transmission box 7 is fixed to the fan 5, the input shaft of the transmission box 7 is fixedly connected to the power output end of the fan 5, and the output shaft of the transmission box 7 is fixedly connected to the exhaust pipe 6.

[0023] In the above scheme, a method of changing the air outlet direction of the fan 5 in real time is proposed. The ventilation duct 2 has two symmetrically distributed ones. A filter plate is installed in the middle of the ventilation duct 2. The filter screen and water-absorbing material are provided on the filter plate to intercept impurities and moisture in the air flowing through. The user needs to replace the filter plate regularly; the first fixed frame 3 and the adjacent wind shield 4 together form a louver fan structure; the transmission box 7 is a reduction box, which is used to reduce the output speed of the fan 5 and drive the exhaust duct 6 to rotate slowly. Initially, the wind shield 4 is in an inclined state, so that the outside air can directly enter the ventilation duct 2 through the first fixed frame 3; a control terminal is provided on the box body 1, and the fan 5 is electrically connected to the control terminal; the air cavity 101 has a horizontal part and a vertical part. The lower side of the vertical part is connected to the ventilation duct 2, and the side of the horizontal part away from the first fixed frame 3 is connected to the box body 1 (the opening faces the lower side).

[0024] Working principle: When using this device, the heat generated by the electrical components will heat the surrounding air to form hot air. Part of the hot air will move upward and be discharged through the exhaust port of the box 1. During this process, the fan 5 is always in working state. The fan 5 draws outside air (hereinafter referred to as cold air) through the ventilation duct 2. The cold air passes between the two adjacent wind shields 4 and the first fixed frame 3 and enters the ventilation duct 2. Then, the cold air enters the exhaust duct 6 through the fan 5. The cold air in the exhaust duct 6 is discharged into the box 1 in a circular diffusion manner through the circular holes thereon. This increases the range covered by the cold air, increases the contact area with the hot air, and improves the efficiency of heat exchange. The cold air pushes the hot air up and discharges it from the exhaust port of the box 1.

[0025] During the operation of the fan 5, the power output end of the fan 5 drives the input shaft of the transmission box 7 to rotate, and the output shaft of the transmission box 7 drives the exhaust duct 6 to rotate slowly. The circular hole on the exhaust duct 6 changes its position at all times, thereby changing the direction of cold air discharge, improving the fluidity of the air in the box, improving the mixing uniformity of the cold air in the box 1, reducing the dead corner area caused by electrical components, further increasing the coverage range of the cold air, ensuring the heat exchange and cooling effect, and thus extending the service life of the electrical components in the box 1.

[0026] Most existing photovoltaic wind turbine boxes have blowers or fans in their air inlet ducts, but the air inlets of the boxes are generally fixed and the air intake cannot be adjusted. In windy and rainy weather, the outside humidity is higher than usual or the wind contains a lot of sand and dust. If the moist or dusty air from the outside is drawn into the box at this time, the internal electrical components will become damp or worn, thereby affecting the normal use of the wind turbine box.

[0027] In the following embodiment, a pressure relief valve is installed in the exhaust port of the box body 1. According to the above embodiment, when the fan 5 is working, the gas in the box body 1 increases, thereby increasing the gas pressure in the box body 1. When the pressure value is greater than the threshold value of the pressure relief valve, the hot air in the box body 1 is discharged from the pressure relief valve.

[0028] Example 2: Based on Example 1, Figure 4 、 Figure 5 and Figure 7-Figure 9 As shown, it also includes: a gas circulation mechanism, the number of which is consistent with the number of ventilation pipes 2, and they are all arranged in the wind cavity 101, for circulating and cooling the gas in the box 1, and the gas circulation mechanism includes: a number of guide blocks 21, which are evenly distributed and are all fixed in the wind cavity 101, and there is a gap between two adjacent guide blocks 21, the box 1 is fixed with a fixed plate 22 near the wind cavity 101, and the box 1 is slidably connected with a sliding plate 23 near the wind cavity 101, and the sliding plate 23 is used to block the fixed plate 22; a driving component is arranged between the ventilation pipe 2 and the first fixed frame 3, for driving the sliding plate 23 to slide and deflect the wind shield 4.

[0029] In the above scheme, a method is proposed for cooling the electrical components in the box 1 in windy and rainy weather and reducing the probability of damage to the electrical components; the guide block 21 is located in the vertical part of the air cavity 101, and is used to guide the hot air passing through and extend the moving path of the hot air; the evenly distributed guide blocks 21 can be divided into five rows (such as Figure 8As shown in the figure, the number of guide blocks 21 in the first, third and fifth rows is odd, the number of guide blocks 21 in the second and fourth rows is even, and the two adjacent groups of guide blocks 21 are staggered, that is, the middle part of a guide block 21 is aligned with the gap between the two adjacent guide blocks 21 of the adjacent group, so as to ensure the dispersion efficiency of the hot air; the fixed plate 22 is provided with grooves distributed in a linear array, so that the fixed plate 22 has the widest part and the narrowest part; the sliding plate 23 is provided with a square hole, and the square hole of the initial sliding plate 23 is aligned with the widest part of the fixed plate 22, and the gas cannot pass through both.

[0030] like Figure 3-Figure 5 and Figure 7-Figure 9 As shown, the driving assembly includes: a first push rod 31, which is fixed to the ventilation pipe 2, and a humidity sensor and a wind erosion sensor are installed on the box body 1 for detecting the humidity and wind and sand in the air, and then deciding whether to stop extracting air from the outside. The first push rod 31, the humidity sensor and the wind erosion sensor are all electrically connected to the control terminal; a second fixed frame 32, which is arranged on the first fixed frame 3, and the wind shield 4 is rotatably connected to the second fixed frame 32; a push rod 33, which is fixed to the telescopic end of the first push rod 31, and the second fixed frame 32 is provided with a second groove 3201, and the second groove 3201 is a straight groove. The push rod 33 is located in the second groove 3201 and slides. The sliding plate 23 is provided with a first groove 2301, and the second groove 3201 is an inclined groove. When the push rod 33 slides in the first groove 2301, the position of the sliding plate 23 changes.

[0031] Working principle: When the device is in use, when the humidity sensor detects that the humidity exceeds the appropriate range (the appropriate range refers to the appropriate use environment of the electrical components in the box 1) or the wind erosion sensor detects wind and sand, the first push rod 31 starts to work (the following description takes the parts at the left ventilation pipe 2 as an example, and takes the humidity exceeding the appropriate range as an example), and its telescopic end drives the push rod 33 to move to the left, and the push rod 33 drives the second fixed frame 32 to move to the left, and the second fixed frame 32 pushes the wind shield 4 thereon to move, and the wind shield 4 begins to deflect counterclockwise (in the front view direction), and the wind shield 4 deflects. During the rotation, the windshield 4 drives the second fixed frame 32 to move upward, and the push rod 33 and the second slot 3201 slide relative to each other in the vertical direction until the windshield 4 rotates to a vertical state. The two adjacent windshields 4 above and below contact each other, so that the outside cold air cannot enter the ventilation duct 2 through the gap between the two adjacent windshields 4, that is, the outside cold air cannot enter the box body 1, reducing the amount of outside humid cold air entering the box body 1, reducing the probability of electrical components getting damp, and thus ensuring the service life of the electrical components. At this time, the push rod 33 contacts the upper side of the second slot 3201.

[0032] In the process of the pushing rod 33 moving to the left, the pushing rod 33 slides along the first groove 2301 and squeezes the sliding plate 23, causing the sliding plate 23 to slide forward. When the pushing rod 33 moves to the rear side of the first groove 2301, the pushing rod 33 contacts the lower side of the second groove 3201, and the square hole of the sliding plate 23 is aligned with the groove of the fixed plate 22. The square hole of the sliding plate 23 is aligned with the narrowest width of the fixed plate 22. The hot air can move from the lower side of the sliding plate 23 to the upper side of the fixed plate 22. At this time, the telescopic end of the first pushing rod 31 stops moving.

[0033] After the telescopic end of the first push rod 31 stops moving, the fan 5 starts to work in the reverse direction. The fan 5 extracts the hot air in the box 1 through the exhaust pipe 6 and makes the hot air enter the ventilation pipe 2. The hot air in the box 1 flows downward. Under the action of the fan 5, the hot air in the ventilation pipe 2 enters the air passage 101 and moves upward. In the process of the hot air moving in the air passage 101, the hot air contacts the side walls of the box 1. At this time, due to the humid environment outside, the temperature outside is lower than that inside the box 1, so that the hot air exchanges heat with the inner wall of the box 1, reducing the temperature of the hot air. When the hot air contacts the guide block 21, the inclined surface of the guide block 21 guides the hot air, causing the hot air to flow to both sides thereof and continue to move upward along the gap between the two adjacent guide blocks 21. The guide block 21 guides the upward moving air, reduces the speed of the hot air movement, extends the moving path of the hot air, thereby ensuring the efficiency of heat exchange and fully reducing the temperature of the hot air.

[0034] After the hot air passes through all the guide blocks 21, the hot air enters the horizontal part of the air cavity 101 and enters the box 1. At this time, the hot gas moves downward after cooling down, cooling the environment inside the box 1, and the pressure inside the box 1 will not change, so the pressure relief valve at the exhaust port on the box will not open.

[0035] When the outside humidity returns to an appropriate range, the telescopic end of the first push rod 31 is retracted and drives all the wind shields 4 to rotate clockwise, so that the two adjacent wind shields 4 lose contact and the outside air can pass through. The telescopic end of the first push rod 31 drives the sliding plate 23 to reset through the push rod 33, so that the sliding plate 23 slides until the square hole on it is aligned with the widest part of the fixed plate 22, and the gas cannot pass through the two. At the same time, the fan 5 starts to work in the forward direction, and then the operating steps of Example 1 are repeated.

[0036] Example 3: Based on Example 2, Figure 1-Figure 3 、 Figure 7 and Figure 8As shown, it also includes: a water cooling mechanism, the number of which is consistent with the number of ventilation pipes 2, both of which are arranged in the box body 1, and are used to cool the air in the air cavity 101. A water tank 41 is fixedly connected to the upper side of the box body 1, and the water cooling mechanism includes: a connecting shell 42, which is fixed in the box body 1 and is connected to the water tank 41 by a first conduit 43; a first pipe network 44, which is connected to the connecting shell 42, the first pipe network 44 is located in the air cavity 101, and the first pipe network 44 passes between two adjacent guide blocks 21; a cleaning component, which is arranged on the first pipe network 44, and is used to drain the water inside it and clean the wind shield 4.

[0037] In the above scheme, a method for strengthening the cooling of the air cavity 101 when it rains is proposed; the water storage tank 41 is located at the top of the box body 1, and a wide-mouth funnel is provided on the upper side of the water storage tank 41 for collecting rainwater; the connecting shell 42 is used to temporarily store and guide rainwater, and a one-way valve is provided at the connection between the connecting shell 42 and the first conduit 43. This one-way valve ensures that rainwater can only flow from the first conduit 43 into the connecting shell 42 and cannot flow in the opposite direction; the first pipe network 44 passes through the gap between the two adjacent guide blocks 21, increasing its contact area with the air and ensuring that the air can fully contact the first pipe network 44. The layout of the first pipe network 44 is the same as the flow path of the hot air; the box body 1 is fixed with the same number of guide blocks as the air cavity 101 (such as Figure 8 As shown), the guide block is used to guide the air flowing upward in the air cavity 101 to both sides, and the guide block is located below the adjacent connecting shell 42.

[0038] like Figure 7 and Figure 10-13 As shown, the cleaning component includes: a plurality of second conduits 51, all of which are connected to the lower side of the first pipe network 44; water spraying parts 52, the number of which is consistent with the number of second conduits 51, and are respectively connected to adjacent second conduits 51, and the water spraying parts 52 are used to spray water onto the windshield 4, thereby completing the cleaning of the adjacent windshield 4.

[0039] Working principle: When it rains outside, the water tank 41 collects rainwater, that is, the water level inside the water tank 41 gradually rises until the water level exceeds the connection between the first conduit 43 and the water tank 41. The water in the water tank 41 flows along the first conduit 43 into the connecting shell 42, and the water in the connecting shell 42 flows into the first pipe network 44, so that the first pipe network 44 is filled with rainwater. In this process, according to the working process of Example 2, when the hot air passes through the air cavity 101, the hot air exchanges heat with the first pipe network 44, thereby further reducing the temperature of the hot air, ensuring the cooling effect on the hot air, and thus effectively reducing the temperature inside the box body 1.

[0040] After the rainwater passes through the first pipe network 44, the rainwater enters the adjacent second duct 51 and is discharged from the water spraying member 52. The discharged rainwater washes the adjacent windshield 4. At this time, the adjacent windshield 4 is in a vertical state, and the water sprayed by the water spraying member 52 can clean all the windshields 4 on the adjacent first fixed frame 3, thereby reducing the dust accumulated thereon and improving the efficiency of air flow.

[0041] After the rain stops, when the water level in the water tank 41 is lower than the connection point between the first conduit 43 and the water tank 41, the water in the water tank 41 stops being discharged, and the water in the water tank 41 is prepared for subsequent use.

[0042] The above embodiment 3 mainly focuses on cooling the hot air in the air cavity 101 when it rains. The following embodiment focuses on cooling the hot air in the air cavity 101 when there is wind and sand.

[0043] Example 4: Based on Example 3, Figure 1-Figure 3 、 Figure 7 and Figure 10-13 As shown, it also includes: a liquid circulation mechanism, which is arranged on the box body 1 and is used to circulate the water in the water tank 41, so as to cool the air in all the wind cavities 101. The liquid circulation mechanism includes: a circulating water pump 61, the number of which is consistent with the number of ventilation pipes 2, both of which are installed on the box body 1, the water inlet pipe of the circulating water pump 61 is connected to the water tank 41, and the communication position of the two is located at the lower part of the water tank 41. The water outlet pipe of the circulating water pump 61 is connected to the adjacent connecting shell 42. The circulating water pump 61 is used to pump out the water stored in the water tank 41 and circulate the water. When the circulating water pump 61 injects water into the connecting shell 42, the connecting shell The water in the shell 42 cannot enter the first conduit 43 (the function of the above-mentioned one-way valve), and the circulating water pump 61 is electrically connected to the control terminal; the second pipe network 63, the number of which is the same as the number of the circulating water pumps 61, is fixed to the box body 1 and is connected to the water tank 41. The connection position between the two is located at the upper part of the water tank 41. All second conduits 51 on the same first pipe network 44 are connected to the adjacent second pipe network 63. The second pipe network 63 is in contact with the outside air and is used to cool the water therein; the number of regulating components is the same as the number of the second pipe networks 63. They are all arranged on the first fixed frame 3 and are used to change the flow direction of the second conduit 51.

[0044] like Figure 12 and Figure 13As shown, the regulating assembly includes: a second push rod 71, which is fixed to the adjacent first fixed frame 3. A protective shell can be installed on the outer side of the second push rod 71 to reduce damage to it and extend its service life. The telescopic end of the second push rod 71 is initially in an extended state; a sliding frame 72, which is fixed to the telescopic end of the second push rod 71. The second conduit 51 is slidably connected to the adjacent sliding frame 72. The sliding frame 72 is located at the lower side of the adjacent second pipe network 63. The second conduit 51 is a tee pipe. The sliding frame 72 is fixed with a blocking plate 73 with the same number as the second conduits 51 on the adjacent first pipe network 44. The blocking plate 73 is used to regulate the flow direction of water in the second conduit 51. By changing the position of the blocking plate 73, the first pipe network 44 is connected to the water spraying member 52 or the first pipe network 44 is connected to the second pipe network 63. Initially, the blocking plate 73 is located at the upper part of the second conduit 51 (higher than the connecting position of the second conduit 51 and the first pipe network 44), so that the first pipe network 44 is connected to the water spraying member 52.

[0045] Working principle: When there is strong wind, since the air contains sand and dust, all wind shields 4 are in a vertically closed state (based on the contents of Example 2), but it is not raining at this time, that is, the water level of the water tank 41 will not continue to rise. At this time, the second push rod 71 is opened, and the telescopic end of the second push rod 71 is retracted and drives the blocking plate 73 thereon to move downward until the blocking plate 73 moves to the lower part of the second conduit 51 (lower than the connection position between the second conduit 51 and the first pipe network 44). At this time, the second push rod 71 stops working, and the first pipe network 44 is connected to the second pipe network 63 through the second conduit 51.

[0046] After the first pipe network 44 is connected to the second pipe network 63 through the second conduit 51, the circulating water pump 61 is turned on to pump out the water in the water tank 41. The water in the water tank 41 enters the connecting shell 42 through the circulating water pump 61, and then the water in the connecting shell 42 enters the first pipe network 44. The process of cooling the hot air in the air cavity 101 in Example 3 is repeated.

[0047] After the water in the first pipe network 44 enters the second conduit 51, all the water in the second conduit 51 enters the second pipe network 63 and flows upward along the second pipe network 63. During this process, the outside wind blows towards the second pipe network 63, cooling the second pipe network 63, thereby reducing the temperature of the water in the second pipe network 63. In this way, the cooled water flows back into the water storage tank 41, and the above-mentioned contents in this embodiment are repeated, so that the cooled water enters the first pipe network 44 again. In this way, the hot air in the air cavity 101 is cooled, ensuring that the temperature in the box body 1 is kept stable.

[0048] After the wind stops, the circulating water pump 61 is turned off, and the telescopic end of the second push rod 71 is reset, and the blocking plate 73 is driven to move to the initial position.

[0049] Example 5: Based on Example 4, Figure 7 、 Figure 11 and Figure 14 As shown, it also includes: a heat dissipation mechanism, the number of which is consistent with the number of the second pipe network 63, and is provided on the box body 1, for dissipating heat for the adjacent second pipe network 63, and the heat dissipation mechanism includes: a third fixed frame 81, fixed to the box body 1; a support frame 82, fixed to the third fixed frame 81, and the support frame 82 is rotatably connected to a plurality of first plates 83, a plurality of second plates 84 and a plurality of third plates 85. A rubber strip is provided on one side of the first plate 83 close to the adjacent third plate 85. The number of the first plate 83, the second plate 84 and the third plate 85 is consistent, and the first plate 83, the second plate 84 and the third plate 85 are .... The third plate 85 is located between the adjacent first plate 83 and the adjacent second plate 84. A torsion spring is fixed between the third plate 85 and the support frame 82. The rubber strip of the first plate 83 and the second plate 84 are both used to limit the third plate 85. The driving assembly is arranged on the third fixed frame 81, and is used to drive the adjacent first plate 83 and the second plate 84 to swing. The driving assembly includes: a third push rod 91, which is fixed to the third fixed frame 81; a driving plate 92, which is slidably connected to the telescopic end of the third push rod 91, and the first plate 83 and the second plate 84 are both rotatably connected to the driving plate 92.

[0050] In the above scheme, a method of dissipating heat and protecting the second pipe network 63 is proposed, so as to extend its service life and improve the heat exchange effect of the second pipe network 63 on the water therein; the first plate 83, the second plate 84 and the third plate 85 are all metal plates, which are used to absorb the heat emitted by the second pipe network 63, and the torsion spring of the third plate 85 is initially in a stored force state; the drive plate 92 is located on the side of the first plate 83 and the second plate 84 away from the third plate 85.

[0051] Working principle: When the circulating water pump 61 is working (in windy and sandy weather), the first plate 83, the second plate 84 and the third plate 85 wrap the second pipe network 63 and absorb the heat of the second pipe network 63, while reducing the damage caused by wind and sand to the second pipe network 63, extending the service life of the second pipe network 63, and ensuring the stability of heat exchange efficiency.

[0052] During the operation of the above-mentioned embodiment 2, when it rains outside, the third push rod 91 starts to work, the telescopic end of the third push rod 91 extends and drives the driving plate 92 to move downward, and the driving plate 92 drives the adjacent first plate 83 and second plate 84 to rotate clockwise (from a front view perspective), the telescopic end of the third push rod 91 slides relative to the driving plate 92, the rubber strip of the first plate 83 loses its limit on the third plate 85, and the third plate 85 rotates counterclockwise under the action of the torsion spring, so that the first plate 83, the second plate 84 and the third plate 85 form a shell with an opening tilted upward. At this time, the falling rainwater enters between the first plate 83 and the second plate 84 along the third plate 85, and the dust on the first plate 83, the second plate 84 and the third plate 85 is washed away by the rainwater, reducing the accumulation of dust on the three and ensuring the heat dissipation area of ​​the first plate 83, the second plate 84 and the third plate 85.

[0053] After the rain stops, the telescopic end of the third push rod 91 is retracted and drives the plate 92 to reset, so that the first plate 83 and the second plate 84 rotate in the opposite direction to reset. At the same time, the second plate 84 squeezes the third plate 85 to reset the third plate 85 and accumulates force on the torsion spring until the telescopic end of the third push rod 91 returns to its initial position. Then, the first plate 83, the second plate 84 and the third plate 85 return to their initial positions, and the above process is repeated during the subsequent raining process.
