Description

Technical Field

[0001] This invention relates to the field of transformers, and in particular to an environmentally friendly dry-type transformer. Background Technology

[0002] Transformers are one of the important pieces of equipment in power distribution systems. In daily life, people often see various types of transformers, such as dry-type transformers. Currently, traditional dry-type transformers are generally box-shaped, and various related components are installed inside the box.

[0003] In response to this situation, the inventor believes that traditional transformers have many internal components, which generate a lot of heat during operation and can easily burn out the components, thus requiring improvement. Summary of the Invention

[0004] The purpose of this application is to provide an environmentally friendly dry-type transformer that can dissipate heat inside the transformer, effectively remove heat, and reduce the damage caused by excessive temperature to the transformer.

[0005] This application provides an environmentally friendly dry-type transformer, which adopts the following technical solution:

[0006] An environmentally friendly dry-type transformer includes: a transformer casing; a heat dissipation vent disposed on the inner wall of the casing; a baffle slidably connected to the inner wall of the casing for blocking the heat dissipation vent; a frame plate installed on the side of the baffle plate and adapted to the heat dissipation vent; an exhaust fan installed inside the frame plate for blowing air to dissipate heat from the inside of the casing; a detection device installed inside the casing for detecting the temperature inside the casing; and a power component installed inside the casing and electrically connected to the detection device for driving the baffle plate to slide.

[0007] By adopting the above technical solution, when the detection device detects that the temperature inside the casing is too high, it will transmit a signal to the power component. The power component will drive the baffle to slide, so that the exhaust fan is aligned with the heat dissipation vent. Turning on the exhaust fan will blow air into the casing to dissipate heat inside the casing. Since multiple exhaust fans are provided, exhaust fans on one side of the casing can blow air while exhaust fans on the other two sides of the casing exhaust air, thereby accelerating the dissipation of heat inside the casing. By adopting this solution, the heat inside the casing can be effectively discharged, reducing the damage to the transformer caused by excessive temperature.

[0008] This application further provides that: an inner frame is provided on the inner side of the frame plate, the exhaust fan is installed in the inner frame, the top and bottom of the outer side of the inner frame are rotatably connected to the frame plate through a rotating rod, and a first driving member is provided on the outer side of the frame plate to drive the inner frame to rotate around the rotating rod.

[0009] By adopting the above technical solution, the inner frame and the frame plate are rotatably connected. When the first driving component is turned on, the inner frame can be driven to rotate around the rotating rod, so that the exhaust fan of the inner frame can exhaust air to the left and right, thus increasing the applicable range of the exhaust fan.

[0010] This application further provides that: a rotating shaft is installed on both sides of the inner frame in the horizontal direction, one end of the rotating shaft located inside the inner frame is fixed to the outer shell of the exhaust fan, a turntable is installed on the inner side of the frame plate near the baffle, a clamping member for clamping the end of the rotating shaft away from the exhaust fan is installed on the turntable, and a second driving member for driving the turntable to rotate is installed on the baffle.

[0011] By adopting the above technical solution, the turntable and clamping components are set up so that the end of the rotating shaft can be clamped, thereby connecting the exhaust fan to the turntable. When the second driving component is turned on, the turntable can be driven to rotate, thereby causing the exhaust fan in the inner frame to swing up and down, thus further increasing its applicable range on the basis of the exhaust fan swinging left and right.

[0012] This application further provides that the clamping component includes: a finger cylinder mounted on a turntable; and a clamping piece mounted on the clamping output end of the finger cylinder.

[0013] By adopting the above technical solution, when the finger cylinder is opened, it can drive the two clamping plates to clamp the two sides of the rotating shaft, thereby fixing the rotating shaft and realizing the connection between the turntable and the rotating shaft. This structure is ingeniously designed and easy to implement.

[0014] This application further provides that: the outer side of the end of the rotating shaft near the clamping member is provided with a clamping plane that is adapted to the clamping plate.

[0015] By adopting the above technical solution, the two clamping planes can increase the contact area between the clamping plates and the clamping planes when the clamping plates hold the rotating shaft, making the rotating shaft more securely clamped and reducing the possibility of slippage.

[0016] This application further provides that: a return spring is fixed on the outer shell of the exhaust fan, and the end of the return spring away from the exhaust fan is fixed on the inner side of the inner frame. When the return spring is in its natural state, the exhaust fan and the baffle are parallel to each other.

[0017] By adopting the above technical solution, the reset spring can have a certain limiting effect on the inner frame, so that the inner frame can remain parallel to the baffle in its natural state, which facilitates the clamping of the rotating shaft by the clamping component.

[0018] This application further provides the following configuration: a box with an open top is provided on the top side of the outer shell; a support plate is slidably connected to the inner wall of the box in a vertical direction; a support plate is rotatably connected to one side of the support plate; a first solar panel is installed on the bearing surface of the support plate; a battery is connected to the first solar panel; the battery is connected to a first driving component, a second driving component, and a power component; a lifting component for driving the support plate to rise and fall is provided inside the box; and a rotating component for driving the support plate to rotate is provided inside the box.

[0019] By adopting the above technical solution, the first solar panel can convert solar energy into electrical energy and store it in a battery, thereby effectively utilizing solar energy and saving unnecessary electrical energy. The rotating component can drive the first solar panel to adjust its angle, thereby adjusting the first solar panel to a suitable position to receive more solar energy.

[0020] This application further provides that the rotating assembly includes: a cylinder vertically installed inside the housing; a pull rope with one end fixed to the top of the cylinder piston rod and the other end passing through the support plate and connected to the side of the support plate away from the hinge end; and a compression spring installed on the bottom of the support plate and the support plate for driving the support plate to rotate in a direction away from the support plate.

[0021] By adopting the above technical solution, when the cylinder is turned on, it can drive the support plate to rotate towards the bearing plate by pulling the rope, while the compression spring can use its own restoring force to drive the support plate to rotate away from the bearing plate. The cooperation between the two can easily realize the adjustment of the rotation angle of the support plate.

[0022] This application further includes: two sliding plates slidably connected to the bottom end face of the support plate; a second solar panel is installed on one side of the sliding plate that is in contact with the support plate; and an electric push rod for driving the sliding plates to slide is installed at the bottom of the support plate.

[0023] By adopting the above technical solution, the electric push rod can drive the slide plate to slide out from both sides of the support plate. During the slide plate's movement, the second solar panel can also slide out, thereby enhancing the solar energy conversion effect based on the first solar panel.

[0024] This application further provides that the bearing surface of the bearing plate is provided with a receiving groove adapted to the sliding plate and the electric push rod.

[0025] By adopting the above technical solution, the accommodating groove can accommodate the support plate when it is reset, reducing the space occupied by the support plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] By setting up an exhaust fan that can swing up and down, when the exhaust fan and the first drive unit are turned on, air can be blown from the left and right to the components inside the housing, which can easily dissipate the heat inside the housing. The second drive unit and the turntable are set up so that when the second drive unit is turned on, the turntable can be driven to rotate, thereby driving the exhaust fan to blow air up and down, thus further increasing the applicable range of the exhaust fan on the basis of swinging left and right.

[0028] The first solar panel can convert solar energy into electrical energy, which is convenient for the use of the electrical device of this application, thereby playing a role in energy conservation and environmental protection. The second solar panel can increase the conversion effect of solar energy based on the first solar panel and further improve the utilization rate of solar energy. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses an environmentally friendly dry-type transformer, such as... Figure 1 and Figure 2 As shown, it includes: the outer casing 1 of the transformer. The outer casing 1 is box-shaped. In order to better dissipate the heat generated inside the outer casing 1, heat dissipation vents 2 are provided on the inner sides of the outer casing 1. A baffle 3 is horizontally slidably installed on the inner wall of the outer casing 1. When the outer casing 1 is not being cooled, the baffle 3 can completely block the heat dissipation vents 2.

[0036] A frame plate 4 is installed on one side of the baffle 3. The size of the frame plate 4 is the same as that of the heat dissipation vent 2. An exhaust fan 41 is installed inside the frame plate 4. A detection device is also installed at a predetermined position inside the housing 1. The detection device is used to detect the temperature inside the housing 1. In this embodiment, the detection device can be a temperature sensor. In addition, a power assembly is also installed inside the housing 1. The power assembly is used to drive the baffle 3 to slide inside the housing 1. It should be noted that the temperature sensor is electrically connected to the power assembly and the exhaust fan 41.

[0037] When the temperature sensor detects that the temperature inside the housing 1 has reached a predetermined value, it will transmit a signal to the exhaust fan 41 and the power component. The power component will drive the baffle 3 to move horizontally, removing the obstruction to the heat dissipation vent 2, so that the frame plate 4 moves to the position corresponding to the heat dissipation vent 2. Then the exhaust fan 41 starts to work. In this embodiment, the exhaust fan 41 can adopt a two-inlet and two-outlet configuration. This configuration allows the heat inside the housing 1 to be quickly discharged with the wind.

[0038] The power assembly of this embodiment includes: two vertical rods 6 that are vertically rotatably installed at the corner of the outer casing 1, a winding rope 61 connected to the vertical rods 6, one end of the winding rope 61 away from the vertical rods 6 being connected to a baffle 3, a rubber strip 63 fixed on the side of the baffle 3 away from the winding rope 61, and a winding motor 62 installed at the bottom or top of the outer casing 1, the output shaft of the winding motor 62 being fixed to the end of the vertical rods 6.

[0039] When it is necessary to drive the baffle 3 to slide, the winding motor 62 can be turned on to drive the vertical rod 6 to rotate. During the rotation, the vertical rod 6 can wind up the winding rope 61, thereby driving the two adjacent baffles 3 to slide against the restoring force of the rubber strip 63. When the temperature sensor detects that the temperature inside the outer casing 1 is lower than the preset value and the exhaust fan 41 is not needed, the winding motor 62 will drive the vertical rod 6 to rotate in the opposite direction. Under the elastic restoring force of the rubber strip 63, the baffle 3 will automatically reset and block the heat dissipation vent 2.

[0040] In order to increase the heat dissipation range of the exhaust fan 41, in this embodiment, an inner frame 42 is provided on the inner side of the frame plate 4, and the exhaust fan 41 is installed in the inner frame 42. The inner frame 42 is rectangular in shape, while the exhaust fan 41 is circular in shape. The top and bottom of the outer side of the inner frame 42 are rotatably installed on the inner wall of the frame plate 4 through a rotating rod. A first driving member is also installed on the top of the outer side of the frame plate 4, and the output shaft of the first driving member is fixed to the rotating rod.

[0041] When the first drive unit is activated, it can drive the inner frame 42 to rotate around the rotating rod, so that the exhaust fan 41 inside the inner frame 42 can swing left and right, thereby effectively increasing the range of air blowing or exhausting by the exhaust fan 41 and effectively improving the heat dissipation effect of the outer casing 1.

[0042] In addition, such as Figure 2 and Figure 3 As shown, rotating shafts 43 are installed on both sides of the inner frame 42 in the horizontal direction. One end of the rotating shaft 43 inside the inner frame 42 is fixed to the outer shell of the exhaust fan 41, and one of the outer ends of the rotating shaft 43 is rotatably connected to the inner wall of the inner frame 42. A turntable 44 is installed on the inner wall of the frame plate 4 near the baffle 3. A clamping member is installed on the turntable 44. The clamping member can clamp and fix the other outer end of the rotating shaft 43 exposed in the inner frame 42. A second driving member for driving the turntable 44 to rotate is also installed on the baffle 3.

[0043] When the second drive unit is activated, it can drive the turntable 44 to rotate. During the rotation of the turntable 44, the rotating shaft 43 can be held by the clamping member and rotated, so that the rotating shaft 43 can drive the exhaust fan 41 to swing up and down, thereby further increasing the applicable range of the exhaust fan 41 on the basis of swinging left and right.

[0044] The clamping component in this embodiment includes a finger cylinder 45 mounted on the turntable 44 and a clamping plate 46 mounted on the clamping output end of the finger cylinder 45. In order to reduce the slippage of the rotating shaft 43 during the clamping process, clamping planes 430 are provided on both sides of the outer end of the rotating shaft 43. When the clamping plate 46 clamps the rotating shaft 43, it will fit against the clamping plane 430, thereby increasing the contact area between the clamping component and the rotating shaft 43, thereby enhancing the firmness of the clamping component in clamping the rotating shaft 43 and reducing the possibility of the rotating shaft 43 becoming loose.

[0045] In addition, in order to facilitate the return of the exhaust fan 41 to its initial position after the clamping member releases the clamping member from the rotating shaft 43, in this embodiment, several return springs 410 are fixed on the outer shell around the exhaust fan 41. The end of the return spring 410 away from the exhaust fan 41 is fixed on the inner side of the inner frame 42. When the return spring 410 is in its natural state, the exhaust fan 41 and the baffle 3 can be parallel to each other.

[0046] It should be noted that both the first and second driving components in this embodiment are servo motors.

[0047] like Figure 4As shown, in order to provide green and environmentally friendly electrical energy to the first drive unit, the second drive unit, and the power component, this embodiment utilizes solar energy to convert it into electrical energy. Specifically, an open box 5 is installed on the top of the outer casing 1, a cover plate 50 is rotatably installed on one side of the top of the box 5, a support plate 51 is slidably connected to the inner wall of the box 5 in the vertical direction, a support plate 52 is rotatably connected to one side of the support plate 51, a first solar panel 53 is attached to the bearing surface of the support plate 52, and a battery is connected to the first solar panel 53. The battery is installed in a predetermined position inside the outer casing 1, and the battery is electrically connected to the first drive unit, the second drive unit, and the power component.

[0048] In addition, a lifting assembly for driving the support plate 51 to rise and fall is provided inside the box 5, and a rotating assembly for driving the support plate 52 to rotate is also installed inside the box 5. The advantage of this arrangement is that when there is sunlight during the day, the lifting assembly can be activated to drive the support plate 51 out, and then the rotating assembly can be activated to drive the support plate 52 to rotate to a predetermined position, so that the first solar panel 53 on the support plate 52 can absorb solar radiation and convert solar energy into electrical energy stored in the battery.

[0049] In this embodiment, the lifting component can be a hydraulic cylinder 59, and the rotating component includes: a cylinder 54 vertically installed in the housing 5, a pull rope 55 with one end fixed to the top of the piston rod of the cylinder 54 and the other end passing through the bearing plate 51 and connected to the side of the support plate 52 away from the hinge end, and a compression spring 56 fixed to the bearing surface of the bearing plate 51 on the bottom side of the support plate 52 away from the pull rope 55.

[0050] When the first solar panel 53 is needed, the hydraulic cylinder 59 can be activated to drive the support plate 51 to rise out of the box 5, and then the cylinder 54 can be activated to extend its piston rod. At this time, the support plate 52 will rotate at a predetermined angle under the elastic action of the compression spring 56 until the first solar panel 53 on the support plate 52 rotates to the predetermined position, so that the first solar panel 53 can receive solar radiation well and convert solar energy into electrical energy stored in the battery.

[0051] In addition, two sliding plates 57 are slidably connected to the bottom end face of the support plate 52. The sliding direction of the two sliding plates 57 is consistent with the length direction of the box body 5. A second solar panel 58 is installed on the side of the sliding plate 57 that is in contact with the support plate 52. An electric push rod for driving the sliding plate 57 to reciprocate is installed at the bottom of the support plate 52.

[0052] When the support plate 52 rotates to the predetermined angle, the electric push rod can be activated to drive the two slide plates 57 to slide. The slide plates 57 can drive the second solar panel 58 to slide out from the bottom of the support plate 52, so that the second solar panel 58 can work together with the first solar panel 53 to receive solar radiation. The advantage of this setting is that it can expand the solar energy conversion area to store more electrical energy.

[0053] In order to reduce the space occupied by the slide plate 57 and the second solar panel 58, in this embodiment, a receiving groove 510 adapted to the slide plate 57 and the electric push rod is provided on the bearing surface of the bearing plate 51. When the first solar panel 53 and the second solar panel 58 are not used, the slide plate 57 can be stored in the bearing plate 51, thereby saving space in the box 5.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
