DETAILED DESCRIPTION

[0020] like Figure 1-Figure 13 As shown, the present invention provides a technical solution: a transformer with a protective function, comprising a base 1, a shell 2 is fixed on the top of the base 1, a transformer body 4 is fixed on the inner wall of the shell 2, and a heat dissipation hole 3 is provided on the side wall of the shell 2. By setting the heat dissipation hole 3, the inside of the shell 2 can be dissipated. A dual-axis motor 6 is fixed on the top of the shell 2, and a fan blade 7 is fixed at the bottom output end of the dual-axis motor 6. An air inlet is provided on the top of the shell 2. When the transformer body 4 is installed and the power is turned on for use, the dual-axis motor 6 is energized to drive the fan blade 7 at the bottom output end to rotate, thereby dissipating heat from the inside of the shell 2. A protective component 5 with good waterproof effect is provided on the top of the shell 2, a shielding component 8 for shielding the heat dissipation hole 3 is provided on the side wall of the shell 2, and a sealing component 9 for protecting the wiring part of the transformer body 4 is provided in the shell 2.

[0021] In order to better protect the equipment from rain, the specific protection component 5 includes a circular groove 501, a disc 510, an alignment hole 511, an elastic telescopic rod 502, a protective cover 503, a water inlet hole 505, a drainage hole 506, a water storage tank 504, a sleeve 507, a connecting spring 509 and an alignment rod 508; a circular groove 501 is opened on the top of the shell 2, and a circular disc 510 is fixed to the output end of the top of the dual-axis motor 6. When the dual-axis motor 6 is energized, the circular disc 510 is driven to rotate, and the elastic telescopic rod 502 is slidably installed on the inner wall of the circular groove 501, and the center point of the circular groove 501 is aligned with the center point of the circular disc 510. A protective cover 503 is fixed on the top of the elastic telescopic rod 502. By setting the protective cover 503, the effect of rain protection can be achieved. Two groups of telescopic rods 502 are provided, and the two groups of elastic telescopic rods 502 are symmetrically arranged with the center line of the protective cover 503 in the vertical direction as the symmetry axis. All water inlet holes 505 are opened on the top of the protective cover 503, and a water storage tank 504 is opened on the protective cover 503, and the water storage tank 504 is connected with the water inlet holes 505. A drainage hole 506 is opened on the outer wall of the protective cover 503, and the drainage hole 506 is connected with the water storage tank 504. When it rains, rainwater can enter the water storage tank 504 through the water inlet holes 505 for collection, and the water in the water storage tank 504 can be discharged through the drainage holes 506. When it rains heavily, the flow rate of rainwater entering the water storage tank 504 through the water inlet holes 505 is greater than the flow rate of rainwater discharged through the drainage holes 506, which will make the water storage tank 504 04, a large amount of water will be collected, making the protective cover 503 heavier, causing the elastic telescopic rod 502 to shrink, and causing the protective cover 503 to move downward. A sleeve 507 is fixed to the inner bottom of the protective cover 503, and an alignment rod 508 is slidably installed on the inner wall of the sleeve 507. An alignment hole 511 is opened on the disk 510, and the diameter of the alignment rod 508 matches the diameter of the alignment hole 511. A connecting spring 509 is fixed to the top of the alignment rod 508, and the top of the connecting spring 509 is fixed to the inner wall of the sleeve 507. By setting the connecting spring 509, the alignment rod 508 can be reset. When the protective cover 503 moves downward, the sleeve 507 and the alignment rod 508 can be driven to move downward. When the alignment rod 508 moves downward to the position aligned with the disk 51 0, when the sleeve 507 continues to move downward, the alignment rod 508 moves into the sleeve 507, compressing the connecting spring 509, and when the disc 510 rotates to align with the alignment hole 511, since the connecting spring 509 is in a compressed state, the alignment rod 508 extends into the alignment hole 511, and then when the disc 510 rotates, it drives the protective cover 503 to rotate, so that the elastic telescopic rod 502 moves in the circular groove 501. When the protective cover 503 rotates, rainwater is thrown off from the top of the protective cover 503, so that the drainage effect is better and the rainwater is prevented from flowing down along the inclined surface of the protective cover 503. When there is too much rain, a large amount of rainwater will flow to the bottom of the shell 2, and the rainwater may flow to the ground and splash.The rain splashes onto the outer wall of the housing 2 and easily enters the housing 2, causing damage to the electrical components, making the protection effect better. When the rain stops, the water in the water storage tank 504 will flow out from the drainage hole 506. Since the protective cover 503 is not affected by the gravity of the rain, and the elastic telescopic rod 502 is in a contracted state, the protective cover 503 will move upward, and through the sleeve 507, the alignment rod 508 can be driven to move out of the alignment hole 511, thereby stopping the rotation of the protective cover 503.

[0022] In order to achieve a better waterproof effect, the specific shielding component 8 includes an L-shaped push rod 801, a support block 802, a rotating rod 803, a shielding plate 804, a rotating block 805, a transmission rod 806, a block 807, a return spring 808, a ring 810 and an L-shaped extrusion rod 809; a transmission rod 806 passes through the top of the shell 2, and is slidably connected at the penetration point, a support block 802 is fixed to the side wall of the shell 2, a rotating rod 803 passes through the support block 802, and is rotatably connected at the penetration point, and the support block 802 can be provided to support the rotating rod 803, and a shielding plate 804 is fixed to the outer wall of the rotating rod 803, and the shielding plate 804 is provided with two groups, The two groups of shielding plates 804 are symmetrically arranged with the center line of the shell 2 in the vertical direction as the symmetry axis. By setting the shielding plates 804, the heat dissipation holes 3 can be shielded and protected. A block 807 is fixed to the bottom of the transmission rod 806, and a return spring 808 is fixed to the top of the block 807. The top of the return spring 808 is fixed to the inner wall of the shell 2. By setting the return spring 808, the transmission rod 806 can be reset. A ring 810 is fixed to the top of the transmission rod 806, and an L-shaped push rod 801 is fixed to the outer wall of the retractable rod of the elastic telescopic rod 502. When the protective cover 503 moves downward, the L-shaped push rod 801 is driven to move downward, and the L-shaped The push rod 801 is in an aligned state with the circular ring 810. When the L-shaped push rod 801 moves downward to contact the circular ring 810, the circular ring 810 is driven to move downward, so that the stopper 807 drives the return spring to stretch 808. An L-shaped extrusion rod 809 is fixed to the outer wall of the circular ring 810, and a rotating block 805 is fixed to the end point of the rotating rod 803. The end of the L-shaped extrusion rod 809 away from the circular ring 810 passes through the through hole opened on the rotating block 805, and the penetration part fits. When the circular ring 810 moves downward, the L-shaped extrusion rod 809 is driven to move downward, so that the L-shaped extrusion rod 809 squeezes the inner side of the rotating block 805, so that the rotating block 805 rotates downward, and the rotating rod 809 03 drives the shielding plate 804 to rotate toward the shell 2, so that the shielding plate 804 can be rotated to block the heat dissipation hole 3 to prevent excessive rain from drifting from the heat dissipation hole 3 into the shell 2, causing damage to the transformer body 4. When the rain stops and the protective cover 503 moves upward, it can drive the L-shaped push rod 801 to move upward without squeezing the ring 810. Because the reset spring 808 is in a stretched state, the transmission rod 806 drives the ring 810 to move upward, and the L-shaped squeezing rod 809 moves upward. The rotating block 805 is driven to rotate upward by the L-shaped squeezing rod 809, and the shielding plate 804 is driven to expand without blocking the heat dissipation hole 3, thereby effectively dissipating heat.

[0023] In order to protect the connection point of the transformer body 4, the specific sealing assembly 9 includes a connecting rod 901, a push block 902, a slide groove 904, a connecting block 903, a moving block 905, a transmission spring 906, a fixed rod 907, a movable rod 909 and an arc-shaped sealing cover 908; the connecting rod 901 passes through the top of the housing 2, and the penetration is slidably connected. The top of the connecting rod 901 is fixed with a push block 902. When the L-shaped extrusion rod 809 moves downward, the L-shaped extrusion rod 809 will squeeze the push block 902 to move downward, so that the connecting rod 901 moves to the bottom of the housing 2. The bottom of the connecting rod 901 is fixed with a connecting block 903. When the connecting rod 901 moves downward, the connecting block 903 is driven to move downward. A sliding groove 904 is provided on the back of the transformer body 4. A moving block 905 is slidably installed on the inner wall of the sliding groove 904. A transmission spring 906 is fixed on one side of the moving block 905. A fixing rod 907 is fixed on the other side of the moving block 905. The side of the transmission spring 906 away from the moving block 905 is fixed on the inner wall of the sliding groove 904. By setting the transmission spring 906, the moving block 90 5, the end of the fixed rod 907 away from the moving block 905 is fixed with an arc-shaped sealing cover 908, the side wall of the moving block 905 is hinged with a movable rod 909, and the end of the movable rod 909 away from the arc-shaped sealing cover 908 is hinged at the bottom of the connecting block 903. When the connecting block 903 moves downward, it squeezes the movable rod 909, causing the movable rod 909 to rotate at the hinge, pushing the moving block 905 to slide in the slide groove 904, driving the transmission spring 906 to stretch, so that the moving block 905 drives the fixed rod 907 The arc-shaped sealing cover 908 and the wiring part of the transformer body 4 are close to each other. The arc-shaped sealing cover 908 can cover and seal the wiring part of the transformer body 4 to prevent excessive rain from causing moisture in the wiring part of the transformer body 4, which is likely to cause corrosion and electrical failure. When the rain stops, the L-shaped extrusion rod 809 will not squeeze the push block 902. Since the transmission spring 906 is in a stretched state, the arc-shaped sealing cover 908 can be kept away from the wiring part of the transformer body 4 to expose the connection part, preventing the heat dissipation from being affected by the cover all the time.

[0024] In order to keep the top of the protective cover 503 clean, a cleaning assembly 10 is provided on the top of the protective assembly 5. Specifically, the cleaning assembly 10 includes a rotating shaft 1001, a rotating rod 1002, a wind cup 1003 and a cleaning scraper 1004. The rotating shaft 1001 is rotatably mounted on the top of the protective cover 503. The rotating rod 1002 is fixed to the outer wall of the rotating shaft 1001. The wind cup 1003 is fixed to the end of the rotating rod 1002. When the wind from the outside blows the wind cup 1003, it drives the wind cup 1003 to rotate, so that the wind cup 100 3 drives the rotating rod 1002 and the rotating shaft 1001 to rotate, and the outer wall of the rotating shaft 1001 is fixed with a cleaning scraper 1004, and the outer wall of the cleaning scraper 1004 is in contact with the outer wall of the top of the protective cover 503. When the rotating shaft 1001 rotates, the cleaning scraper 1004 is driven to rotate in contact with the top of the protective cover 503, so as to scrape off the impurities attached to the top of the protective cover 503, and prevent some larger leaves from falling on the top of the protective cover 503 and blocking the water inlet 505, which will affect the water inlet amount of the water inlet 505.

[0025] Working principle: When encountering heavy rain, the flow rate of rainwater entering the water storage tank 504 through the water inlet hole 505 is greater than the flow rate of rainwater discharged from the drainage hole 506, which will cause a large amount of water to be collected in the water storage tank 504, making the protective cover 503 heavier, causing the elastic telescopic rod 502 to shrink, and causing the protective cover 503 to move downward, which can drive the sleeve 507 and the alignment rod 508 to move downward. When the alignment rod 508 moves downward to contact the top of the disc 510, when the sleeve 507 continues to move downward, the alignment rod 508 moves into the sleeve 507, compressing the connecting spring 509, and when the disc 510 rotates to contact the alignment hole 511 During alignment, since the connecting spring 509 is in a compressed state, the alignment rod 508 extends into the alignment hole 511, and then when the disc 510 rotates, the protective cover 503 is driven to rotate, so that the elastic telescopic rod 502 moves in the circular groove 501. When the protective cover 503 rotates, rainwater is thrown off from the top of the protective cover 503, so that the drainage effect is better and the rainwater is prevented from flowing down along the inclined surface of the protective cover 503. When there is too much rain, a large amount of rainwater will flow to the bottom of the shell 2, and the rainwater may flow to the ground and splash, causing the rainwater to splash onto the outer wall of the shell 2 and easily enter the shell 2, causing damage to electrical components.

[0026] When the protective cover 503 moves downward, it drives the L-shaped push rod 801 downward, and the L-shaped push rod 801 is aligned with the ring 810. When the L-shaped push rod 801 moves downward to contact the ring 810, it drives the ring 810 downward, so that the block 807 drives the reset spring to stretch 808. When the ring 810 moves downward, it drives the L-shaped extrusion rod 809 downward, so that the L-shaped extrusion rod 809 squeezes the inner side of the rotating block 805, so that the rotating block 805 rotates downward, so that the rotating rod 803 drives the shielding plate 804 to rotate toward the shell 2, so that the shielding plate 804 can be rotated to block the heat dissipation hole 3 to prevent excessive rain from floating from the heat dissipation hole 3 into the shell 2, causing damage to the transformer body 4.

[0027] When the L-shaped extrusion rod 809 moves downward, it will squeeze the push block 902 and move it downward, so that the connecting rod 901 moves downward. When the connecting rod 901 moves downward, it will drive the connecting block 903 to move downward, which will squeeze the movable rod 909, so that the movable rod 909 rotates at the hinge, and push the moving block 905 to slide in the slide groove 904, driving the transmission spring 906 to stretch, so that the moving block 905 drives the fixed rod 907 and the arc-shaped sealing cover 908 to approach each other at the wiring point of the transformer body 4. The wiring point of the transformer body 4 can be covered and sealed by the arc-shaped sealing cover 908 to prevent excessive rain from causing moisture at the wiring point of the transformer body 4, which is easy to cause corrosion and electrical failure.

[0028] When the heavy rain stops, the rainwater will be discharged from the drainage hole 506. Since the protective cover 503 is not affected by the gravity of the rainwater and the elastic telescopic rod 502 is in a contracted state, the protective cover 503 will move upward, and through the sleeve 507, the alignment rod 508 can be driven to move out of the alignment hole 511, thereby stopping the rotation of the protective cover 503. When the protective cover 503 moves upward, it can drive the L-shaped push rod 801 to move upward without squeezing the ring 810. Since the reset spring 808 is in a stretched state, the transmission The movable rod 806 drives the ring 810 to move upward, so that the L-shaped extrusion rod 809 moves upward, and the rotating block 805 is driven to rotate upward by the L-shaped extrusion rod 809, so as to drive the shielding plate 804 to expand without blocking the heat dissipation hole 3, so as to effectively dissipate heat, and when the L-shaped extrusion rod 809 moves upward, it does not squeeze the push block 902, because the transmission spring 906 is in a stretched state, so that the arc-shaped sealing cover 908 can be kept away from the wiring of the transformer body 4, so that the connection is exposed, to prevent the cover from affecting the heat dissipation.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
