Description

Technical Field

[0001] The invention relates to a substation, and in particular to a dispersed combined photovoltaic substation. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN211654526U discloses an oil-immersed heat dissipation device for a primary system of a substation, including a cooling water pipe, which is installed outside the transformer body, and the transformer body is installed on the left side of the upper end surface of the base; a waterproof cover is provided on the left side of the upper end surface of the base outside the cooling water pipe, and a cooling water tank is installed in the middle of the upper end surface of the base; a floating mechanism is slidably connected at an angle on the rear side of the cooling water tank; a water storage mechanism is provided on the right side of the upper end surface of the base, and a controller with a rain cover is installed on the rear end surface of the water storage mechanism; the water storage mechanism and the cooling water tank are both filled with water; the floating mechanism floats on the surface of the water source in the cooling water tank; a circulating pump is connected between the cooling water pipe and the cooling water tank through a water pipe, and a start switch and a stop switch that are electrically connected to the controller in common are installed on the rear end surface of the cooling water tank through a support plate; the start switch is located below the stop switch, and a rain shield that is slidably connected to the support plate is provided on the upper part of the start switch; sliding columns that are slidably connected to the support plate are provided at four angles on the bottom end surface of the rain shield.

[0003] Through the setting of the floating mechanism, when a large amount of water evaporates from the water source inside the cooling water tank, the floating mechanism loses its buoyancy in the cooling water tank and will slide downward in the cooling water tank. When the bottom end surface of the floating mechanism slides down to a position below the starting switch, the counterweight block presses the button on the starting switch through the rain shield, and then starts the water adding pump through the controller, so that the water source inside the water storage mechanism is added to the cooling water tank through the water adding pipe.

[0004] The cooling water tank can be filled with water in time, and the water filling operation can be performed automatically without manual operation, which will not affect the heat dissipation effect of the heat dissipation device, and the cooling water tank after water is added will not reduce the heat dissipation effect of the circulating water pipe.

[0005] With the abnormal climate in recent years, there is usually less precipitation and stronger wind in the central and western regions of my country, which makes air cooling occupy a larger proportion of heat dissipation. In this heat dissipation device, the wind blows onto the circulating water pipe to dissipate the heat of the cooling oil. However, when used outdoors, a large amount of dust falls on the circulating water pipe due to gravity, which will seriously affect the heat dissipation effect. Summary of the invention

[0006] In view of this, an object of the present invention is to provide a dispersed combined photovoltaic substation to reduce dust adhesion and improve heat dissipation effect.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: a distributed combined photovoltaic substation, including a main body, an oil inlet pipe, an oil outlet pipe, and an oil storage cabinet, one end of the oil inlet pipe and one end of the oil outlet pipe are both connected to the main body, the oil storage cabinet is fixed on the main body and connected to the main body through an oil filling pipe, the horizontal height of the oil storage cabinet is higher than the horizontal height of the oil outlet pipe, the horizontal height of the oil outlet pipe is higher than the horizontal height of the oil inlet pipe, and also includes a vertically arranged heat sink located between the oil inlet pipe and the oil outlet pipe, a plurality of the heat sinks are arranged in parallel, and there is a heat dissipation gap between adjacent heat sinks, the upper end of the heat sink is connected to the oil outlet pipe, and the lower end of the heat sink is connected to the oil inlet pipe.

[0008] To implement the above technical solution, the heat sink is placed vertically, and most of the dust can fall on the upper surface of the heat sink due to gravity, while the impact on the side of the heat sink that plays a major role in heat dissipation is relatively small, so the overall heat dissipation state of the heat sink is less affected. By setting the heat dissipation gap, each heat sink has a better heat dissipation effect, thereby eliminating the process of workers frequently cleaning the surface of the heat sink.

[0009] As a preferred solution of the present invention, an upper main pipeline, a lower main pipeline and a heat dissipation pipeline are provided in the heat sink, the upper main pipeline is horizontally placed and the upper end of the upper main pipeline is connected to the oil outlet pipe, the lower main pipeline is horizontally placed and the lower end of the lower main pipeline is connected to the oil inlet pipe, the heat dissipation pipeline is vertically arranged and one end is connected to the upper main pipeline, and the other end of the heat dissipation pipeline is connected to the lower main pipeline, the upper main pipeline and the lower main pipeline are arranged in parallel, and a plurality of the heat dissipation pipelines are arranged along the length direction of the upper main pipeline.

[0010] To implement the above technical solution, the heat dissipation oil enters into multiple heat dissipation pipes from the upper main pipe, and the contact area with the air is increased, thereby achieving the purpose of improving the cooling effect of the heat dissipation oil. After the heat dissipation oil is cooled in the heat dissipation pipe, the cooled heat dissipation oil enters into the lower main pipe, and then enters into the main body from the lower main pipe, thereby realizing the heat dissipation oil circulation.

[0011] As a preferred solution of the present invention, it also includes a reinforcement plate, which is fixed on the outer wall of the heat sink, and a plurality of heat sinks are arranged along the length direction of the reinforcement plate.

[0012] By implementing the above technical solution, the reinforcement plate improves the structural strength of the heat sink, making it less likely for the heat sink to be deformed or damaged due to side wind.

[0014] To implement the above technical solution, in the process of the heat dissipation oil moving from top to bottom along the heat dissipation pipe, the heat dissipation oil drives the paddle to rotate, the paddle drives the driving rod to rotate through the gear assembly, the driving rod drives the rotating disk to rotate through the linkage structure, and the rotating disk drives the rocker arm to swing back and forth through the power mechanism. In the process of the reciprocating swing of the rocker arm, the rubber sheet is made to swing back and forth to scrape off the dust on the side of the heat sink, thereby further improving the heat dissipation. The flow of heat dissipation oil can make the rubber sheet swing. When it rains, a large amount of sludge will be distributed on the lower part of the heat sink. The mud and sand will be scraped off by the rubber sheet, so that the surface of the heat sink can be kept clean for a long time.

[0015] As a preferred solution of the present invention, the linkage structure includes a first gear and a second gear, the first gear is fixed on the driving rod, the second gear is fixed on the rotating disk, and the first gear is meshed with the second gear.

[0016] To implement the above technical solution, the driving rod rotates, the driving rod drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the rotating disk to rotate, and the transmission is stable.

[0017] As a preferred solution of the present invention, the power mechanism includes a swing assembly, a fixed frame, a connecting rod, an elastic member, and a slider. The rotating disk drives the swing shaft to swing through the swing assembly. The fixed frame is fixedly connected to the swing rod, and the slider is slidably connected to the fixed frame. One end of the elastic member is connected to the slider, and the other end of the elastic member is connected to the inner wall of the fixed frame. The two ends of the connecting rod are respectively hinged to the slider and the support frame.

[0018] To implement the above technical solution, the rotating disk rotates, the swing shaft is swung through the swing assembly, the swing shaft drives the swing arm to swing, the swing arm moves in the direction close to the connection between the connecting rod and the support frame, the slider moves along the fixed frame and compresses the elastic member, when the swing arm and the connecting rod are in the same line, this is the center line, the compression of the elastic member is the largest, as the swing arm continues to move, the elastic force of the elastic member causes the swing arm to move quickly in the direction away from the center line, the swing arm and the connecting rod are both in an inclined state, the elastic force of the elastic member keeps the swing arm in position, thereby realizing the reciprocating swing of the swing arm, the rubber sheet moves synchronously with the swing arm to scrape off most of the mud and sand on the side wall of the heat sink, so that the heat sink can maintain a good heat dissipation effect for a long time.

[0019] As a preferred solution of the present invention, a slide groove is provided on the support frame, the length direction of the slide groove extends in the direction of the rocker arm, an adjusting rod is rotatably connected to the support frame and penetrates into the slide groove, an adjusting block is threadedly connected to the adjusting rod, the adjusting block is slidably connected in the slide groove, and the end of the connecting rod away from the slider is hinged to the adjusting block.

[0020] To implement the above technical solution, the adjusting rod is rotated in the forward direction, and the adjusting block moves along the slide groove toward the elastic member. The self-locking property of the thread enables the adjusting block to position itself in the slide groove. At this time, the swing amplitude of the pendulum rod is increased, that is, the speed of the pendulum rod when leaving the center line is increased, thereby improving the effect of scraping off mud and sand, so as to facilitate scraping off foreign matter attached to the surface of the heat sink. Similarly, when the adjusting rod is rotated in the reverse direction, the swing amplitude of the pendulum rod becomes smaller, which is suitable for conventional use in scraping off mud and sand.

[0021] As a preferred solution of the present invention, a storage tank for storing cleaning liquid is fixedly connected to the support frame, a first through hole is provided on the support frame, the rocker arm and the rocker shaft are hollow, a second through hole for communicating with the first through hole is provided on the rocker shaft, the first through hole and the second through hole are staggered when the direction of the rocker arm and the length direction of the connecting rod are collinear, and a discharge hole communicating with the inner wall of the rocker arm is provided on the outer wall of the rocker arm.

[0022] To implement the above technical solution, as the swing arm swings, the first through hole and the second through hole are connected when the direction of the swing arm and the length direction of the connecting rod are not collinear. Under the action of gravity, the cleaning liquid in the storage tank enters the swing arm along the first through hole and the second through hole, and is then discharged from the swing arm along the discharge hole and coated on the surface of the heat sink to dissolve foreign matter, thereby improving the cleaning effect.

[0023] As a preferred solution of the present invention, a limiting ring is fixedly connected to the inner wall of the rocker arm, a push plate is slidably connected inside the rocker arm, an extension rod is fixedly connected to the push plate, a contact plate is fixedly connected to the slider, and the slider moves toward the direction close to the elastic member so that the contact plate pushes the push plate along the length direction of the rocker arm through the extension rod.

[0024] To implement the above technical solution, the adjusting rod is rotated forward, and the adjusting block moves to the end of the slide groove in the direction close to the elastic member. In the process of the rocker arm moving closer to the center line, the stroke of the slider along the fixed frame becomes larger, that is, the compression of the elastic member becomes larger. At this time, the first through hole and the second through hole are misaligned, and the contact plate drives the extension rod to move, and the push plate moves along the length direction of the rocker arm. The cleaning liquid is squeezed out from the discharge hole. When the rocker arm moves to the end of the stroke, the first through hole and the second through hole correspond, and the cleaning liquid is injected into the inside of the rocker arm, and the push plate moves down and is supported by the limit ring. This is a strong cleaning mode; the adjusting rod is rotated in the opposite direction, and the adjusting block moves to the end of the slide groove in the direction away from the elastic member. At this time, no matter where the slider is, the contact plate cannot contact the extension rod. This is a light cleaning mode.

[0026] To implement the above technical solution, the driving disk rotates, the triangular block rotates along the axis of the driving disk, and when the triangular block conflicts with the first boss, the first boss moves upward along the triangular block. Through the principle of leverage, the end of the fixed plate close to the first boss tilts upward, and the swing shaft rotates with the fixed plate; similarly, when the triangular block conflicts with the second boss, the end of the fixed plate close to the second boss tilts upward.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. The driving rod is driven by the flow of heat dissipation oil, eliminating the need for additional power mechanisms and saving energy.

[0029] 2. The adjusting rod rotates and the adjusting block moves to the lower end of the slide. At this time, it is a light cleaning mode and the swing rod leaves the center line slowly;

In addition, the cleaning liquid will flow into the swing arm by gravity when the swing arm moves to the end of the stroke, so as to realize the process of automatic filling of the cleaning liquid.

[0040] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0041] A distributed photovoltaic substation includes a main body 1, an oil inlet pipe 11, an oil outlet pipe 12, and an oil storage cabinet 13. One end of the oil inlet pipe 11 and one end of the oil outlet pipe 12 are both connected to the main body 1; the oil outlet pipe 12 and the oil inlet pipe 11 are both arranged horizontally, the oil outlet pipe 12 is close to the upper edge of the main body 1, and the oil inlet pipe 11 is close to the lower edge of the main body 1.

[0042] The oil storage cabinet 13 is fixed to the upper end of the main body 1 and is connected to the main body 1 through the oil filling pipe 14 .

[0043] The heat sink 2 is arranged in a rectangular shape as a whole. A plurality of heat sinks 2 are arranged in parallel and placed vertically, and a heat dissipation gap is provided between two adjacent heat sinks 2 .

[0044] An upper main pipe 21, a lower main pipe 22, and a heat dissipation pipe 23 are provided in the heat sink 2. The upper main pipe 21 is horizontally arranged and the upper end of the upper main pipe 21 is connected to the oil outlet pipe 12, and the lower main pipe 22 is horizontally arranged and the lower end of the lower main pipe 22 is connected to the oil inlet pipe 11. The heat dissipation pipe 23 is vertically arranged and one end is connected to the upper main pipe 21, and the other end of the heat dissipation pipe 23 is connected to the lower main pipe 22. The upper main pipe 21 and the lower main pipe 22 are arranged in parallel, and a plurality of heat dissipation pipes 23 are arranged along the length direction of the upper main pipe 21.

[0045] The heat dissipation oil enters the upper main pipe 21 from the oil outlet pipe 12, and then enters multiple heat dissipation pipes 23 for diversion and heat dissipation. Since the contact area between the side wall of the heat sink 2 and the air is large, the heat dissipation oil can be cooled quickly. The cooled heat dissipation oil flows into the lower main pipe 22, and finally flows back to the main body 1 from the oil inlet pipe 11.

[0046] The reinforcement plate 20 is horizontally arranged and fixed on the outer wall of the heat sink 2 , and a plurality of heat sinks 2 are arranged along the length direction of the reinforcement plate 20 .

[0047] A support frame 3 is fixedly connected to the outer wall of the oil outlet pipe 12, and the support frame 3 is close to the upper edge of the heat dissipation gap. A horizontally arranged driving rod 31 is rotatably connected to the support frame 3, a rotating shaft 32 is rotatably connected in the heat dissipation pipe 23, and a plurality of blades 33 are evenly fixedly connected to the outer wall of the rotating shaft 32. A first bevel gear 34 is fixedly connected to the rotating shaft 32, and a second bevel gear 35 is fixedly connected to the driving rod 31, and the first bevel gear 34 and the second bevel gear 35 are meshed.

[0048] A rotating disk 41 is rotatably connected to the support frame 3, and the driving rod 31 drives the rotating disk 41 to rotate through a linkage structure 42. The linkage structure 42 includes a first gear 43 and a second gear 44. The first gear 43 is fixed to the driving rod 31 and is coaxially arranged; the second gear 44 is fixed to the rotating disk 41 and is coaxially arranged, and the first gear 43 meshes with the second gear 44.

[0049] A horizontally arranged swing shaft 51 is rotatably connected to the support frame 3 , and the axis of the swing shaft 51 is colinear with the axis of the driving rod 31 .

[0050] A swing rod 52 is vertically fixedly connected to the swing shaft 51, and a rubber sheet 53 for contacting the surface of the heat sink 2 is connected to the outer wall of the swing rod 52. One rubber sheet 53 contacts the outer walls of two adjacent heat sinks 2 at the same time.

[0051] The rotating disk 41 drives the swing rod 52 to swing back and forth through the power mechanism 6.

[0052] The power mechanism 6 includes a swing assembly 7, a fixed frame 61, a connecting rod 62, an elastic member 63, and a slider 64. The rotating disk 41 drives the swing shaft 51 to swing through the swing assembly 7. The swing assembly 7 includes a triangular block 71, a fixed plate 72, a first boss 73, and a second boss 74. The lengths of the first boss 73 and the second boss 74 are equal. The fixed plate 72 is fixedly connected to the outer wall of the swing shaft 51, and the swing shaft 51 is located in the middle of the fixed plate 72. The first boss 73 and the second boss 74 are respectively fixed to the two ends of the fixed plate 72. The triangular block 71 is fixed to the edge of the rotating disk 41, and the triangular block 71 is used to conflict with the first boss 73 or the second boss 74. The first boss 73 and the second boss 74 are respectively located at the two ends of the diameter of the rotating disk 41.

[0053] The fixed frame 61 is fixedly connected to the swing rod 52, and the length direction of the fixed frame 61 is parallel to the length direction of the swing rod 52. The slider 64 is slidably connected in the fixed frame 61. One end of the elastic member 63 is connected to the slider 64, and the other end of the elastic member 63 is connected to the inner wall of the fixed frame 61. The two ends of the connecting rod 62 are respectively hinged to the slider 64 and the support frame 3. The elastic member 63 is a spring.

[0054] The line connecting the axis of the swing shaft 51, the hinge of the connecting rod 62 and the slider 64, and the hinge of the connecting rod 62 and the support frame 3 is the center line. At this time, the compression of the elastic member 63 is the largest, and the swing rod 52 and the connecting rod 62 are collinear and vertically arranged.

[0055] In order to increase the swing amplitude of the swing rod 52, that is, the deformation amount of the elastic member 63 becomes larger. A slide groove 81 is provided on the support frame 3, and the slide groove 81 is vertically arranged. The length direction of the slide groove 81 extends in the direction of the swing rod 52. An adjustment rod 82 inserted into the slide groove 81 is rotatably connected to the support frame 3, and the adjustment rod 82 is vertically arranged. The adjustment rod 82 penetrates into the slide groove 81, and an adjustment block 83 is threadedly connected to the adjustment rod 82, and the adjustment block 83 is slidably connected to the slide groove 81. One end of the connecting rod 62 away from the slider 64 is hinged to the adjustment block 83.

[0056] Rotate the adjusting rod 82 in the forward direction, and the adjusting block 83 moves up along the slide groove 81 through the conduction effect of the thread. When the adjusting block 83 moves to the upper end of the slide groove 81, the connecting rod 62 moves synchronously with the adjusting block 83. When the swing rod 52 moves toward the direction close to the center line, the connecting rod 62 drives the slider 64 to move along the length direction of the fixed frame 61 to the maximum extent. At this time, the compression amount of the elastic member 63 is the largest, and the speed at which the swing rod 52 leaves the center is also the largest. At this time, the swing speed of the swing rod 52 is the fastest. This is the strong cleaning mode.

[0057] Similarly, the adjusting rod 82 is rotated in the opposite direction to move the adjusting block 83 downward along the slide groove 81. When the adjusting block 83 moves to the lower end of the slide groove 81, the swing speed of the swing rod 52 is the slowest, which is the light cleaning mode.

[0058] In order to further improve the cleaning effect, a storage tank 91 for storing cleaning liquid is fixedly connected to the support frame 3, and the cleaning liquid is a mixture of detergent and water. A first through hole 92 is provided on the support frame 3, and two first through holes 92 are arranged obliquely. The swing arm 52 and the swing shaft 51 are hollow, and a second through hole 93 for communicating with the first through hole 92 is provided on the swing shaft 51. When the direction of the swing arm 52 and the length direction of the connecting rod 62 are collinear, the first through hole 92 and the second through hole 93 are misaligned. In the strong cleaning mode, when the swing arm 52 moves to the end of the stroke, the first through hole 92 and the second through hole 93 correspond to each other. At this time, the cleaning liquid passes through the first through hole 92 and the second through hole 93 into the inside of the swing arm 52 through the action of gravity.

[0059] A discharge hole 94 is provided on the outer wall of the swing rod 52 and is connected to the inner wall of the swing rod 52 , so that the cleaning liquid can be coated on the outer wall of the heat sink 2 after being discharged from the discharge hole 94 , thereby improving the cleaning effect on the heat sink 2 .

[0060] A limit ring 95 is fixedly connected to the inner wall of the swing rod 52 , and a push plate 98 is slidably connected inside the swing rod 52 . The push plate 98 is located above the limit ring 95 , and the limit ring 95 supports the push plate 98 .

[0061] An extension rod 96 is fixedly connected to the push plate 98, and the extension rod 96 passes through the limiting ring 95. A contact plate 97 arranged in an L shape is fixedly connected to the slider 64.

[0062] In the strong cleaning mode, the contact plate 97 can contact the extension rod 96. When the swing rod 52 is close to the center line, the slider 64 moves toward the elastic member 63 to make the contact plate 97 and the extension rod 96, and the extension rod 96 pushes the push plate 98 along the length direction of the swing rod 52. At this time, the first through hole 92 and the second through hole 93 are misaligned, and the cleaning liquid is squeezed out from the discharge hole 94. After the swing rod 52 bypasses the center line, the slider 64 moves away from the elastic member 63, the first through hole 92 and the second through hole 93 correspond, and the push plate 98 conflicts with the limit ring 95 due to gravity, and the cleaning liquid is injected into the inside of the swing rod 52.

[0063] In the light cleaning mode, the contact plate 97 cannot contact the extension rod 96 .

[0064] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
