Description

Technical Field

[0001] The invention belongs to the field of power distribution cabinets, in particular to a power distribution cabinet for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form a large-area solar cell module, which is combined with power controllers and other components to form a photovoltaic power generation device. In a photovoltaic power station, a distribution cabinet needs to be installed. The distribution cabinet is a general term for the motor control center.

[0003] Existing photovoltaic power distribution cabinets are generally installed outdoors. In the hot summer, the distribution cabinet will generate severe heat due to a large workload, which often causes damage to the internal electrical equipment. Most of the existing technologies dissipate heat from the distribution cabinet through fans and heat dissipation holes, but the heat dissipation effect is limited. The heat dissipation holes alone cannot discharge the heat in time. When encountering heavy rainfall, excessive rainwater can easily submerge the distribution cabinet, causing water to enter the distribution cabinet. The existing technology is not convenient for protecting the distribution cabinet during heavy rainfall, and it is not convenient for utilizing rainwater, resulting in a waste of resources.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 9As shown, the present invention provides a technical solution, a photovoltaic power distribution cabinet, including a base 1, four brackets 2 are symmetrically fixedly connected to the top of the base 1, the outer walls of the four brackets 2 are slidably connected to the first slider 4, a cabinet 5 is fixedly connected between the four first sliders 4, the outer wall of the cabinet 5 is rotatably connected to the cabinet door 6, a top plate 3 is fixedly connected between the tops of the four brackets 2, the top of the top plate 3 is set as a symmetrical inclined surface, the outer wall of the base 1 is fixedly connected to the first motor 7, the output end of the first motor 7 extends to the inside of the base 1 and is fixedly connected to a bidirectional screw rod 8, the bidirectional screw rod 8 is rotatably connected to the base 1, the outer wall of the bidirectional screw rod 8 is connected to two second sliders 9 through a screw nut pair, the two second sliders 9 are symmetrically installed, the tops of the two second sliders 9 are rotatably connected to support plates 10, and the two support plates 10 are rotatably connected to the cabinet 5.

[0024] Through the above technical solution, the base 1 is installed on the foundation. When it rains, the first motor 7 is started to drive the bidirectional screw 8 to rotate, so that the two second sliders 9 are close to each other. The cabinet 5 is pushed to move upward through the two support plates 10, so that the cabinet 5 is close to the top plate 3. The top plate 3 can block the rain for the cabinet 5 to prevent rainwater from falling into the cabinet 5, and the position of the cabinet 5 rises after it is close to the top plate 3, which can prevent the cabinet 5 from being submerged by accumulated water. After the rain stops and the weather is hot, the two second sliders 9 are controlled by the first motor 7 to move away from each other. Under the pull of the two support plates 10, the cabinet 5 is driven to move downward and away from the top plate 3. Because hot air floats upward, after the obstruction of the top plate 3 is lost, the heat in the cabinet 5 can be discharged upward in time.

[0025] Specifically, several groups of heat dissipation components are arranged on both sides of the cabinet 5, and the heat dissipation components include a first fin 20 and a second fin 25. The first fin 20 and the second fin 25 are both fixed on the side of the cabinet 5. The first fin 20 is arranged in a V shape, and the second fin 25 is arranged in an inverted V shape. The length of the first fin 20 is greater than the length of the second fin 25, and the first fin 20 and the second fin 25 are staggered.

[0026] Through the above technical solution, the contact area between the cabinet 5 and the surrounding air is increased by setting the first fin 20 and the second fin 25, and the heat dissipation surface is expanded so that the heat in the cabinet 5 can be transferred to the air more quickly, thereby effectively reducing the temperature inside the cabinet 5.

[0027] Specifically, a first through groove 21 is opened inside the first fin 20, two first water inlets 23 are symmetrically opened on the top of the first fin 20, a first water outlet 24 is opened at the bottom of the first fin 20, the first water inlet 23 and the first water outlet 24 are both communicated with the first through groove 21, a second through groove 26 is opened inside the second fin 25, a second water inlet 28 is opened on the top of the second fin 25, the second water inlet 28 is communicated with the second through groove 26, and a side plate 42 is fixedly connected to one side of the first fin 20, and the top of the side plate 42 and the top of the first water inlet 23 are located in the same horizontal plane.

[0028] Through the above technical solution, the side plate 42 installed blocks one side of the first fin 20, so that the concave surface of the first fin 20 cooperates with the side plate 42 to form a water storage groove. When it rains, rainwater can slide along the inclined surface of the top of the top plate 3 into the concave surface of the first fin 20 to store rainwater. Because water has a high specific heat capacity, when rainwater is stored on the first fin 20, it can quickly absorb the heat on the first fin 20, so that the temperature of the first fin 20 is reduced, which helps to improve the heat conduction efficiency and transfer the heat inside the cabinet 5 to the external environment faster. When the liquid level is flush with the first water inlet 23, rainwater enters the first fin 20 along the first water inlet 23 and flows in the first through groove 21 to further cool the first fin 20. When the rainwater in the first through groove 21 flows to the bottom, it falls from the first water outlet 24, enters the second water inlet 28, and flows in the second fin 25 along the second through groove 26 to cool the second fin 25. When the rainwater in the second through groove 26 flows to the bottom, it enters the first fin 20 below along the first water inlet 23 below, thereby better utilizing rainwater for cooling.

[0029] Specifically, a plurality of first baffles 22 are equidistantly fixedly connected to the bottom of the inner wall of the first through groove 21, and the first baffles 22 are arranged in an arc shape and tilted upward. A plurality of second baffles 27 are equidistantly fixedly connected to the bottom of the inner wall of the second through groove 26, and the second baffles 27 are arranged in an arc shape and tilted upward.

[0030] Through the above technical solution, the first baffle 22 and the second baffle 27 are set to slow down the flow rate of rainwater in the first through groove 21 and the second through groove 26, thereby extending the cooling time of the first fin 20 and the second fin 25 by rainwater, and a part of the rainwater can be accumulated at the first baffle 22 and the second baffle 27, so that the rainwater can stay in the first fin 20 and the second fin 25, and continue to cool the first fin 20 and the second fin 25.

[0031] Specifically, a water storage chamber is provided at the top of the base 1, and an annular inclined groove 41 used in conjunction with the water storage chamber is provided at the top of the base 1. The cabinet 5 fits the inner wall of the water storage chamber, and two third water inlets 29 are symmetrically provided at the bottom of the cabinet 5. A first water inlet groove 30 is provided inside the cabinet 5 and at the top of the third water inlet 29. A second water inlet groove 31 is provided inside the cabinet 5 and at the top of the first water inlet groove 30. Two second water outlets 33 are symmetrically provided on the outer wall of the cabinet 5 and above the heat dissipation component. Both second water outlets 33 are communicated with the second water inlet groove 31. A diverter block 32 is fixedly connected to the top of the inner wall of the second water inlet groove 31, and the bottom of the diverter block 32 is set as a symmetrical inclined surface.

[0032] Through the above technical scheme, rainwater can be stored in the water storage chamber. When the weather is hot and there is a lack of water for heat dissipation, the cabinet 5 is controlled by the first motor 7 to move downward and enter the water storage chamber. Under the squeezing of the cabinet 5, the rainwater flows upward along the third water inlet 29 and flows along the first water inlet groove 30 and the second water inlet groove 31. In this way, the cabinet 5 can be cooled and the heat in the cabinet 5 can be taken away as soon as possible. The rainwater that passes through the second water inlet groove 31 falls from the second water outlet 33 and falls into the first water inlet 23. Similarly, the first fin 20 and the second fin 25 are cooled, thereby better and more reasonably utilizing the rainwater to dissipate heat from the cabinet 5.

[0033] Specifically, two water receiving plates 48 are symmetrically fixedly connected to both sides of the cabinet 5 and below the heat dissipation assembly. The two water receiving plates 48 are both installed at an angle, and drainage grooves 49 are provided inside the two water receiving plates 48 .

[0034] Through the above technical solution, rainwater falling from the second fin 25 at the bottom falls on the water receiving plate 48 and slides down along the slope of the water receiving plate 48, so that the rainwater flows along the outer wall of the cabinet 5. The falling rainwater falls along the drainage groove 49 and re-enters the water storage chamber from the annular inclined groove 41.

[0035] Specifically, a plurality of water storage plates 44 are equidistantly fixedly connected to the inner wall of the cabinet 5, a fourth water inlet 43 is opened between the water storage plates 44 and the first water inlet trough 30, and a plurality of drainage plates 45 are equidistantly fixedly connected to the inner wall of the first water inlet trough 30. The drainage plates 45 are installed at an angle and are located on the upper side of the adjacent fourth water inlet 43. The drainage plates 45 are used in conjunction with the fourth water inlet 43.

[0036] Through the above technical solution, rainwater flowing upward at the first water inlet trough 30 is blocked by the drain plate 45 when passing through the fourth water inlet 43, and a part of it enters the water storage plate 44 along the inclined surface of the drain plate 45, so that the rainwater can be stored in the water storage plate 44. Since the water storage plate 44 is located inside the cabinet 5, the stored rainwater can better absorb the heat in the cabinet 5 and cool the cabinet 5.

[0037] Specifically, a plurality of heat dissipation grooves 53 are equidistantly provided on the outer wall of the cabinet 5, and a plurality of dustproof plates 54 are equidistantly fixedly connected to the outer wall of the cabinet 5. The dustproof plates 54 are located on the upper side of the heat dissipation grooves 53, and the dustproof plates 54 are used in conjunction with the heat dissipation grooves 53. A second motor 50 is fixedly connected to the bottom of the inner wall of the cabinet 5, and a turntable 51 is fixedly connected to the output end of the second motor 50. Six spoilers 52 are fixedly connected to the outer wall of the turntable 51 at equal intervals, and the six spoilers 52 are all installed at an angle. A first guide plate 46 is fixedly connected to the bottom of the water storage plate 44, and the first guide plate 46 is arranged in an arc shape and inclined toward the inner wall of the cabinet 5. A second guide plate 47 is fixedly connected to the bottom of the first guide plate 46, and the second guide plate 47 is arranged in an arc shape and inclined toward the side away from the inner wall of the cabinet 5.

[0038] Through the above technical solution, the second motor 50 is started to drive the turntable 51 to rotate, so that the six spoilers 52 rotate. The spoiler plates 52 rotate to form an upward vortex, so that the heat in the cabinet 5 can be quickly discharged upward. The hot air is blocked by the second guide plate 47 when flowing upward, and part of its heat flows upward along the concave surface of the second guide plate 47 into the first guide plate 46. The concave surface formed by the first guide plate 46 blocks the hot air, so that the hot air can stay at the water storage plate 44 for a long time. The rainwater in the water storage plate 44 not only takes away the heat in the hot air, but also can further dissipate the heat of the cabinet 5 after the rainwater evaporates.

[0039] Specifically, the top of the cabinet 5 is symmetrically and slidably connected with two first sliding shafts 11, the tops of the two first sliding shafts 11 are fixedly connected with a fixing frame 13, the outer walls of the two first sliding shafts 11 are sleeved with a first spring 12, the bottom of the first spring 12 is fixedly connected to the cabinet 5, the top of the first spring 12 is fixedly connected to the fixing frame 13, the inner wall of the fixing frame 13 is fixedly connected with a rotating shaft 14, the outer wall of the rotating shaft 14 is symmetrically and rotatably connected with two first filter plates 15, one side of the two first filter plates 15 is fixedly connected with a counterweight 16, the bottom of the top plate 3 is symmetrically and fixedly connected with two fixing rods 17, the inner walls of the two fixing rods 17 are slidably connected with a top block 19, a second spring 18 is arranged inside the fixing rod 17, one end of the second spring 18 is fixedly connected to the fixing rod 17, the other end of the second spring 18 is fixedly connected to the top block 19, the top and bottom of the top block 19 are both arranged as inclined surfaces, the top block 19 is used in conjunction with the fixing frame 13, and the elastic force of the second spring 18 is greater than the elastic force of the first spring 12.

[0040] Through the above technical solution, when the cabinet 5 moves downward to open the top for heat dissipation, the two first filter plates 15 are provided to prevent dust from entering the cabinet 5. By providing two counterweights 16, the two first filter plates 15 are placed in an inclined state to prevent leaves and other debris from accumulating on the first filter plates 15. When the control cabinet 5 moves upward, the fixing frame 13 and the two first filter plates 15 are driven to move upward. After the fixing frame 13 contacts the top block 19, the fixing frame 13 moves toward the cabinet 5 when the top block 19 is squeezed, so that the first sliding shaft 11 slides in the cabinet 5 and the first spring 12 is pressed. As the fixing frame 13 moves toward the cabinet 5, the two first filter plates 15 rotate on the rotating shaft 14 at the same time and fit the top of the cabinet 5. When the first spring 12 is compressed to the limit, the fixing frame 13 presses against the inclined surface of the top block 19 and pushes the top block 19 to slide into the fixing rod 17, pressing the second spring 18. After the obstruction of the top block 19 is lost, under the action of the first spring 12, the fixing frame 13 is pushed to move upward quickly and reset, thereby driving the two first filter plates 15 to rotate and vibrate upward at the same time, so as to shake off the dust on the first filter plates 15 and maintain the ventilation effect of the first filter plates 15.

[0041] Specifically, the bottom of the cabinet 5 is symmetrically and slidably connected with two second sliding shafts 34, the tops of the two second sliding shafts 34 are fixedly connected to the limit plates 35, the two limit plates 35 are slidably connected to the cabinet 5, the bottoms of the two second sliding shafts 34 are fixedly connected with the second filter plates 37, the outer walls of the two second sliding shafts 34 are sleeved with third springs 36, the tops of the third springs 36 are fixedly connected to the limit plates 35, and the bottoms of the third springs 36 are fixedly connected to the cabinet 5, the inner wall of the base 1 is symmetrically and slidably connected with two clamping blocks 39, the tops and bottoms of the two clamping blocks 39 are both set as inclined surfaces, and two fourth springs 40 are symmetrically arranged inside the base 1, one end of the fourth spring 40 is fixedly connected to the clamping block 39, and the other end of the fourth spring 40 is fixedly connected to the base 1, the elastic force of the fourth spring 40 is greater than the elastic force of the third spring 36, and the outer wall of the second filter plate 37 is provided with a clamping groove 38 used to cooperate with the clamping block 39.

[0042] Through the above technical solution, the third water inlet 29 is blocked by the second filter plate 37. After the control cabinet 5 moves downward into the water storage chamber, the rainwater in the water storage chamber is filtered to prevent debris in the water from entering the third water inlet 29. When the control cabinet 5 moves upward and out of the water storage chamber, the second filter plate 37 is driven to move upward. When the slot 38 moves to the same horizontal plane as the block 39, the block 39 enters the slot 38 under the action of the fourth spring 40, and the second filter plate 37 is limited by the block 39. At this time, as the cabinet 5 moves upward, the second sliding shaft 34 is driven to slide in the cabinet 5, pressing the third spring 36. When the third spring 36 is compressed to the limit, the slot 38 presses against the inclined surface at the bottom of the block 39 and pushes the block 39 to move toward the inside of the base 1, pressing the fourth spring 40. After the block 39 is no longer limited, the second filter plate 37 is moved upward and vibrated under the action of the third spring 36. By vibrating the second filter plate 37, the debris at the bottom of the second filter plate 37 can be shaken off, thereby maintaining the filtering effect of the second filter plate 37.

[0043] When in use, the base 1 is installed on the foundation, and the contact area between the cabinet 5 and the surrounding air is increased by the first fin 20 and the second fin 25. By expanding the heat dissipation surface, the heat in the cabinet 5 can be transferred to the air more quickly, thereby effectively reducing the temperature inside the cabinet 5. When it rains, the first motor 7 is started to drive the bidirectional screw rod 8 to rotate, so that the two second sliders 9 are close to each other, and the cabinet 5 is pushed to move upward through the two support plates 10, so that the cabinet 5 is close to the top plate 3. The top plate 3 can shield the cabinet 5 from rain and prevent rainwater from falling into the cabinet 5. The cabinet 5 is raised after it is close to the top plate 3, which can prevent the cabinet 5 from being submerged by accumulated water. The side plate 42 installed blocks one side of the first fin 20 so that the first fin 20 The concave surface cooperates with the side plate 42 to form an empty groove for storing water. When it rains, rainwater can slide down the inclined surface on the top of the top plate 3 into the concave surface of the first fin 20 to store rainwater. Because water has a higher specific heat capacity, when rainwater is stored on the first fin 20, it can quickly absorb the heat on the first fin 20, so that the temperature of the first fin 20 is reduced, which helps to improve the heat conduction efficiency and transfer the heat inside the cabinet 5 to the external environment more quickly. When the liquid level of the stored rainwater is flush with the first water inlet 23, the rainwater enters the first fin 20 along the first water inlet 23 and flows in the first through groove 21 to further cool the first fin 20. When the rainwater in the first through groove 21 flows to the bottom, it falls from the first water outlet 24 and enters the second The rainwater flows into the water inlet 28 and flows along the second through groove 26 in the second fin 25 to cool the second fin 25. When the rainwater in the second through groove 26 flows to the bottom, it enters the first fin 20 below along the first water inlet 23 below, thereby making better use of the rainwater for cooling. The first baffle 22 and the second baffle 27 are provided to slow down the flow speed of the rainwater in the first through groove 21 and the second through groove 26, and prolong the cooling time of the rainwater on the first fin 20 and the second fin 25. The first baffle 22 and the second baffle 27 can store a part of the rainwater, so that the rainwater can stay in the first fin 20 and the second fin 25, and continue to cool the first fin 20 and the second fin 25. The rainwater can be stored in the water storage cavity when it rains, and the rainwater can be stored in the water storage cavity. The rainwater stored in the water storage chamber, falling from the second fin 25 at the bottom falls on the water receiving plate 48, and slides down along the slope of the water receiving plate 48, so that the rainwater flows along the outer wall of the cabinet 5, and the falling rainwater falls along the drainage groove 49, and re-enters the water storage chamber from the annular inclined groove 41. When the rain stops and the weather is hot, the two second sliders 9 are controlled to move away from each other by the first motor 7. Under the pull of the two support plates 10, the cabinet 5 is driven to move downward and away from the top plate 3. Because the hot air floats upward, after losing the obstruction of the top plate 3, the heat in the cabinet 5 can be discharged upward in time. When the cabinet 5 moves downward to open the top for heat dissipation, the two first filter plates 15 are provided to prevent dust from entering the cabinet 5. By providing two counterweights 16,The two first filter plates 15 are placed in an inclined state to prevent leaves and other debris from accumulating on the first filter plates 15. The cabinet 5 moves downward and enters the water storage chamber. Under the squeezing of the cabinet 5, the rainwater flows upward along the third water inlet 29 and flows along the first water inlet groove 30 and the second water inlet groove 31, thereby cooling the cabinet 5 and taking away the heat in the cabinet 5 as soon as possible. The third water inlet 29 is blocked by the second filter plate 37. After the cabinet 5 is controlled to move downward and enter the water storage chamber, the rainwater in the water storage chamber is filtered to prevent debris in the water from entering the third water inlet 29. The rainwater that passes through the second water inlet groove 31 falls from the second water outlet 33 and falls into the first water inlet 23. Similarly, the first fin 20 and the second fin 25 are cooled. In this way, rainwater is more reasonably utilized to dissipate heat from the cabinet 5. Rainwater flowing upward from the first water inlet trough 30 is blocked by the guide plate 45 when passing through the fourth water inlet 43, and a part of it enters the water storage plate 44 along the inclined surface of the guide plate 45, so that rainwater can be stored in the water storage plate 44. Since the water storage plate 44 is located inside the cabinet 5, the stored rainwater can better absorb the heat in the cabinet 5 and cool the cabinet 5. The second motor 50 is started to drive the turntable 51 to rotate, so that the six spoilers 52 rotate. The spoilers 52 rotate to form an upward vortex, so that the heat in the cabinet 5 can be quickly discharged upward. The hot air is blocked by the second guide plate 47 when flowing upward, and part of its heat flows upward along the inner concave surface of the second guide plate 47 and enters the first guide plate 46, the concave surface formed by the first guide plate 46 blocks the hot air, so that the hot air can stay at the water storage plate 44 for a long time. The rainwater in the water storage plate 44 not only takes away the heat in the hot air, but also can further dissipate the heat of the cabinet 5 after the rainwater evaporates. When the control cabinet 5 moves upward, the fixing frame 13 and the two first filter plates 15 are driven to move upward. After the fixing frame 13 contacts the top block 19, when the top block 19 is squeezed, the fixing frame 13 moves toward the cabinet 5, so that the first sliding shaft 11 slides in the cabinet 5, and the first spring 12 is pressed. As the fixing frame 13 moves toward the cabinet 5, the two first filter plates 15 rotate on the rotating shaft 14 at the same time and fit the top of the cabinet 5. When the first spring 12 is compressed to the limit, the fixing frame 13 presses against the inclined surface of the top block 19 and The top block 19 is pushed to slide into the fixing rod 17, and the second spring 18 is compressed. After the obstruction of the top block 19 is removed, the fixing frame 13 is pushed to move upward quickly and reset under the action of the first spring 12, thereby driving the two first filter plates 15 to rotate and vibrate upward at the same time, so as to shake off the dust on the first filter plates 15 and maintain the ventilation effect of the first filter plates 15. When the control cabinet 5 moves upward and out of the water storage chamber, the second filter plate 37 is driven to move upward. When the slot 38 moves to the same horizontal plane as the block 39, the block 39 enters the slot 38 under the action of the fourth spring 40, and the second filter plate 37 is limited by the block 39. At this time, as the cabinet 5 moves upward, the second sliding shaft 34 is driven to slide in the cabinet 5, and the third spring 36 is compressed.When the third spring 36 is compressed to the limit, the slot 38 presses against the inclined surface at the bottom of the block 39 and pushes the block 39 to move inside the base 1, compressing the fourth spring 40. After the block 39 is no longer limited, the second filter plate 37 moves upward and vibrates under the action of the third spring 36. By vibrating the second filter plate 37, the debris at the bottom of the second filter plate 37 can be shaken off, and the filtering effect of the second filter plate 37 is maintained.
