[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For example, see Figures 1 to 10 The present invention discloses an outdoor transformer with a protective function, comprising a protective cabinet 1, a ventilation hole 41 is opened on one side of the protective cabinet 1, a ventilation window 4 is arranged outside the ventilation hole 41, a collecting tank 2 is arranged on one side of the outer wall of the protective cabinet 1, a collecting seat 5 is arranged at the bottom of the protective cabinet 1, a guide pipe 20 is arranged between the collecting tank 2 and the collecting seat 5, an elastic connecting component is arranged at the bottom of the collecting seat 5, a baffle 39 is connected to the top of the collecting seat 5 through a connecting rod 40, and the baffle 39 is slidably connected to the inner side of the ventilation window 4.

[0029] In this embodiment, a baffle 39 is slidably provided on one side of the vent 41. On a sunny day, the baffle 39 is located on the upper side of the vent 41. The transformer is ventilated and heat-dissipated through the vent 41. A ventilation window 4 is provided outside the vent 41 for dust prevention. It should be noted that the top of the protective cabinet 1 is set as a sloping roof, and the inclination angle of the sloping roof is set to 10°-15°. The inclined top can effectively prevent the infiltration of external liquids such as rainwater, while reducing dust accumulation, providing protection for electrical equipment. Therefore, when it rains, rainwater flows into the collection trough 2 through the top of the protective cabinet 1, and the rainwater flows into the collection seat 5 through the guide pipe 20 at the bottom of the collection trough 2. When the amount of rainwater reaches a certain volume, the collection seat 5 moves downward, driving the baffle 39 to move downward, so that the vent 41 is blocked, preventing rainwater from entering the protective cabinet 1 and protecting the transformer.

[0030] The elastic connection component includes a hollow tube 6 fixedly connected to the protective cabinet 1, a support shaft 8 is connected to the bottom of the collecting seat 5, the bottom end of the support shaft 8 is slidably connected to the hollow tube 6, the outer wall of the support shaft 8 is sleeved with a first spring 7, and two groups of drainage pipes 9 are connected to the bottom of the collecting seat 5, and the drainage pipes 9 extend to the outside of the protective cabinet 1. After the rain stops, the rainwater is discharged from the collecting seat 5 through the drainage pipes 9 to avoid long-term accumulation of rainwater in the collecting seat 5, which affects the reset of the collecting seat 5 and makes it impossible to complete the heat dissipation work on rainy days disclosed in this application.

[0031] An overflow port is provided on one side of the top of the collecting seat 5 , and the overflow port is connected to the side wall of the protective cabinet 1 through a hose. The hose connection is provided to ensure that the lifting and falling of the collecting seat 5 does not interfere with the protective cabinet 1 .

[0032] It should be noted that in order to prevent the water vapor in the collection seat 5 from evaporating into the protection cabinet 1 and causing damage to the transformer, an overflow port is provided on one side of the top of the collection seat 5. When the rainwater in the collection seat 5 exceeds the internal volume of the collection seat 5, it can be discharged from the overflow port.

[0033] In this embodiment, a hollow tube 6, a first spring 7 and a support shaft 8 are sequentially arranged at the bottom of the collecting seat 5. After collecting rainwater, the collecting seat 5 moves downward, compressing the first spring 7, so that the support shaft 8 extends into the hollow tube 6; when the rain stops and the rainwater is discharged from the drain pipe 9, the pressure on the collecting seat 5 is reduced, and the first spring 7 is reset, so that the support shaft 8 moves upward, lifting the collecting seat 5, thereby using the connecting rod 40 to drive the baffle 39 to move upward, so that the vent 41 is exposed for ventilation and heat dissipation.

[0034] It should be noted that on rainy days, when the vent 41 is blocked by the baffle 39, the protection cabinet 1 can be flushed with rainwater to achieve a cooling effect. At the same time, the collected rainwater is introduced into the collection seat 5 in the protection cabinet 1 by the guide pipe 20, and then discharged through the drain pipe 9, so as to discharge part of the heat in the protection cabinet 1, thereby dissipating the heat of the protection cabinet 1.

[0035] It should be noted that, in order to prevent the transformer and other electrical components in the protection cabinet 1 from getting damp, a second cover plate 47 is installed on the collection seat 5 to seal the collection seat 5 .

[0036] It should be noted that the bottom end of the flow guide tube 20 is connected to the second cover plate 47 via a hose to avoid interference between the lifting and lowering of the collecting seat 5 and the flow guide tube 20 .

[0037] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 The collecting tank 2 is provided with a first cover plate 3, one side of the first cover plate 3 is pinned to the other side of the collecting tank 2, a top rod 33 is slidably connected in the collecting tank 2, the bottom ends of two groups of top rods 33 are connected to a top plate 34, four groups of positioning blocks 36 are symmetrically arranged at the bottom of the collecting tank 2, a driving shaft 35 is slidably installed in the positioning blocks 36, and a sixth spring 44 is arranged between two adjacent groups of positioning blocks 36. A support rod 38 is connected to the collecting seat 5, one end of the support rod 38 is connected to a lifting plate 37, and the lifting plate 37 is fitted with one end of the driving shaft 35.

[0038] In this embodiment, a flip-up first cover plate 3 is provided above the collecting tank 2. The first cover plate 3 is a mesh plate structure, which can filter larger impurities, such as leaves, plastic bags, etc., and avoid them from falling into the collecting tank 2 as much as possible.

[0039] Two groups of driving shafts 35 are symmetrically arranged at the bottom of the collecting trough 2, and the driving shafts 35 are elastically connected to the positioning block 36 through the sixth spring 44. A top plate 34 is arranged at one end of the driving shaft 35, and a seventh spring 46 is connected between the top rod 33 and the collecting trough 2. When the collecting seat 5 increases with the amount of rainwater collected, the collecting seat 5 moves downward, driving the support rod 38 and the lifting plate 37 to move downward. The lifting plate 37 is provided with an inclined surface close to the side of the driving shaft 35. After the high point of the inclined surface contacts the driving shaft 35, the driving shaft 35 is pushed toward the top plate 34. The top plate 34 is applied with force by the driving shaft 35, and the inclined surface opened along one side of the top plate 34 pushes the top plate 34 and the top rod 33 upward, so that the first cover plate 3 is lifted by the top rod 33, so that impurities on the first cover plate 3 are washed off by the rainwater, thereby cleaning the surface of the first cover plate 3.

[0040] It should be noted that the flipping angle of the first cover plate 3 is in the range of 35°-45°, which can ensure that the surface of the first cover plate 3 is cleaned after flipping and can also be self-repositioned after the lifting force of the ejector rod 33 is lost.

[0041] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 A movable seat 10 is arranged in the collecting tank 2, and the movable seat 10 is connected to the collecting tank 2 through a second spring 12. Two groups of water discharge holes 15 are symmetrically opened at the bottom of the movable seat 10, and two groups of push plates 19 are symmetrically arranged on both sides of the movable seat 10. The push plates 19 and the movable seat 10 are slidably connected, and a filter plate 16 is arranged on one side of the movable seat 10 in the collecting tank 2.

[0042] In this embodiment, a movable seat 10 is set in the collecting trough 2. When rainwater flows into the collecting trough 2, it first flows into the movable seat 10. When the movable seat 10 is full of rainwater, it can release the rainwater in an instant to flush the collecting trough 2, thereby preventing dust or other impurities from accumulating in the collecting trough 2.

[0043] It should be noted that a filter plate 16 is provided on one side of the collection tank 2 to filter rainwater entering the guide pipe 20, so as to make the rainwater collected by the guide pipe 20 as pure as possible, and to ensure that the guide pipe 20 is not blocked during long-term use.

[0044] Drain holes 18 are equidistantly provided at the bottom of the collecting tank 2 , and a drainage bucket 45 is connected to the outer surface of the collecting tank 2 below the drainage holes 18 , and the guide pipe 20 and the drainage bucket 45 are fixedly connected.

[0045] In this embodiment, a plurality of drainage holes 18 are provided on one side of the filter plate 16 in the collection trough 2, a drainage bucket 45 is provided below the drainage holes 18, and a guide pipe 20 is connected to the bottom of the drainage bucket 45. Rainwater is guided to the collection seat 5 through the drainage holes 18, the drainage bucket 45 and the guide pipe 20, thereby completing the collection of rainwater and finally being discharged through the drainage pipe 9.

[0046] Four groups of second springs 12 are symmetrically arranged at the bottom of the movable seat 10, two groups of sealing plates 13 are symmetrically arranged in the collecting tank 2, the sealing plates 13 and the drain holes 15 are matched, a magnet 11 is arranged on the inner wall of the collecting tank 2, the magnet 11 and the movable seat 10 are matched, and a sewage outlet 14 is opened in the center of the bottom of the collecting tank 2 and directly below the movable seat 10.

[0047] Specifically, a second spring 12 is provided at the bottom of the movable seat 10, and the installation position of the sealing plate 13 matches the drainage hole 15 opened in the movable seat 10. At the same time, the magnet 11 is used to limit the initial position of the movable seat 10. When rainwater continuously pours into the movable seat 10, the weight increases and exceeds the magnetic attraction of the magnet 11, and the movable seat 10 and the magnet 11 are separated, compressing the second spring 12 to fall downward. At this time, the sealing plate 13 remains stationary, so that the sealing plate 13 and the drainage hole 15 are separated, and the rainwater in the movable seat 10 flows out instantly, impacting the push plate 19, driving the push plate 19 to move to both sides, flushing the collection tank 2, and at the same time, the push plate 19 can be used to scrape off the accumulated impurities on the bottom surface of the collection tank 2.

[0048] A fourth spring 21 is connected between the push plate 19 and the inner wall of the collecting tank 2. Drainage ports 22 are symmetrically provided on both sides of the collecting tank 2. A brush plate 43 is connected to one side of the two sets of push plates 19. The brush plate 43 is fitted to one side of the filter plate 16.

[0049] It should be noted that, considering that some impurities may exist outside the collecting tank 2, the push plate 19 cannot clean the impurities in the above-mentioned position during the movement. Therefore, a drain outlet 14 is opened at the bottom of the collecting tank 2 below the movable seat 10. When the rainwater discharge of the movable seat 10 is completed, the pulling force of the fourth spring 21 drives the push plate 19 to reset, so that the dust and impurities remaining between the two groups of push plates 19 are discharged through the drain outlet 14.

[0050] It should be noted that a plug 53 is provided at the bottom of the movable seat 10. When the movable seat 10 falls, the plug 53 can be used to block the sewage outlet 14 to ensure the impact force of drainage after the movable seat 10 falls.

[0051] A first limit block 48 is connected to one side of the push plate 19, and a second limit block 50 is slidably connected to one side of the filter plate 16 through an eighth spring 49. A pressure rod is connected to one side of the second limit block 50. The eighth spring 49 of the pressure rod is inside. When 19 moves to the position of blocking the drain outlet 22, the first limit block 48 and the second limit block 50 cooperate to limit 19.

[0052] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 A second wedge block 25 is connected to the side of the movable seat 10 close to the filter plate 16, and a first wedge block 23 is arranged on one side of the filter plate 16. The first wedge block 23 and the second wedge block 25 are matched with each other, and a spring rod 24 is arranged between the first wedge block 23 and the filter plate 16. Two sets of third springs 17 are connected between the filter plate 16 and the collecting tank 2.

[0053] In this embodiment, a limiting mechanism is provided between the movable seat 10 and the filter plate 16, specifically including a first wedge block 23, a spring rod 24 and a second wedge block 25. When the movable seat 10 falls, the second wedge block 25 moves down with the movable seat 10. When the second wedge block 25 and the first wedge block 23 are fitted together, the spring rod 24 is squeezed by gravity, so that the second wedge block 25 moves down to the bottom of the first wedge block 23. After the spring rod 24 is reset, the first wedge block 23 is used to limit the second wedge block 25, so as to ensure that after the movable seat 10 moves down, the sealing plate 13 and the drain hole 15 are kept separated, so that the rainwater collected in the movable seat 10 is completely discharged, thereby ensuring the impact force of the movable seat 10 during the drainage process.

[0054] It should be noted that the spring rod 24 includes a shaft rod 51 for connecting the first wedge block 23 and the filter plate 16 , and the shaft rod 51 and the filter plate 16 are slidably connected, and a ninth spring 52 is sleeved on the outer wall of the shaft rod 51 .

[0055] Example 5: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10A fixing ring 32 is provided on one side of the third spring 17, and a push rod 29 is installed in the fixing ring 32. The push rod 29 slides through the collecting tank 2 and the movable seat 10 in sequence. A limiting ring 31 is provided on the surface of the push rod 29, and a fifth spring 30 is connected between the limiting ring 31 and the inner wall of the collecting tank 2. A cushion block 42 is symmetrically provided on the inner wall of the first cover plate 3, and the push rod 29 and the cushion block 42 are matched.

[0056] In this embodiment, push rods 29 are symmetrically arranged in the collecting trough 2. As the rainwater in the movable seat 10 is discharged, the push plate 19 blocks the drain port 22, and the rainwater passes through the filter plate 16, and enters the collecting seat 5 via the drain hole 18, the drain bucket 45 and the guide pipe 20. The rainwater in the collecting seat 5 increases, and the collecting seat 5 moves downward, pushing the first cover plate 3 to flip up. A cushion block 42 is arranged in the first cover plate 3. As the first cover plate 3 flips over, the cushion block 42 contacts with the push rod 29, pushing the push rod 29 to move toward the filter plate 16. The push rod 29 is connected to the filter plate 16 through the fixing ring 32. Therefore, the movement of the push rod 29 can push the filter plate 16 to one side, thereby canceling the limiting effect of the first wedge block 23 on the second wedge block 25, so that the collecting seat 5 is reset. After resetting, the collecting seat 5 and the magnet 11 are attracted to continue collecting rainwater.

[0057] It should be noted that the push rod 29 penetrates between the push plate 19 and the movable seat 10 , which effectively avoids interference between the push plate 19 and the push rod 29 during the movement.

[0058] It should be noted that after the filter plate 16 is pushed, the push plate 19 is reset under the elastic action of the fourth spring 21 .

[0059] Example 6: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 The push plate 19 is connected with a connecting rod 26 , the collecting seat 5 is connected with a column 27 , the top of the column 27 is connected with an adjusting plate 28 , and the connecting rod 26 extends to the bottom of the adjusting plate 28 .

[0060] In this embodiment, a column 27 is connected above the collecting seat 5, and an adjustment plate 28 is connected between the two groups of columns 27. Inclined surfaces are provided on both sides of the adjustment plate 28. When the collecting seat 5 descends, the collecting seat 5 will drive the adjustment plate 28 to move downward. The connecting rod 26 can be pushed in the opposite direction by the guidance of the inclined surface, so that the push plate 19 moves to the drain outlet 22, prompting the collecting trough 2 to be closed, so that rainwater enters the collecting seat 5 through the filter plate 16, thereby ensuring the rainwater collection effect, and the drainage speed of the drain pipe 9 is slow, thereby further completing the residence time of rainwater inside the protective cabinet 1, and better improving the cooling effect of the air temperature in the protective cabinet 1.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
