TECHNICAL FIELD
[0001] The application relates to the technical field of power equipment, and particularly relates to an intelligent large power transformer. BACKGROUND
[0002] The transformer is a kind of static electrical equipment used for transforming AC voltage and current to transmit AC power, and it realizes power transmission according to the principle of electromagnetic induction. The transformer can be divided into power transformers, test transformers, instrument transformers and transformers for special purposes according to its use. The power transformer is a necessary device for power transmission and distribution and power user distribution, and its functions are various. It can not only raise the voltage to send the power to the power consumption area, but also reduce the voltage to the power consumption voltage of each level to meet the needs of power consumption.
[0003] Or as provided in the publication No. "CN113205946B", a power transformer, which is rotated by the action of wind force, so as to drive the rod body connected with the first connecting sleeve to move, so that the push block moves slidingly between the shell and the partition plate, the gas in the extrusion space is extruded, so that the piston is pressed down, and the bristles can clean the outer wall of the heat sink plate, and the collected rainwater can be used for auxiliary cleaning, so that the surface of the heat sink plate of the power transformer can be automatically cleaned by using clean energy.
[0004] However, the patent technology has the following problems in actual implementation:
[0005] The cleaning structure cannot be targeted to clean the heat sink plate. For example, in strong wind weather, the wind can quickly take away the heat on the surface of the heat sink plate, achieving good heat dissipation effect of the power transformer, but the cleaning brush still cleans at this time, which can cause the bristles to continuously rotate at normal temperature of the heat sink plate, resulting in invalid wear. More importantly, the bristles will scratch the coating of the heat sink fins of the power transformer after excessive wear, which will reduce the heat radiation rate of the heat sink plate. In addition, in weak wind weather, the strength of the wind is low and the continuity of the wind is intermittent, which makes it difficult to support the cleaning structure to complete a cleaning cycle, resulting in unsatisfactory cleaning effect and difficulty in stable maintenance, so as to guarantee the service life of the power transformer.

[0033] The technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] Example 1, please refer to Figures 1-8 A smart large power transformer includes a transformer body 1, a heat sink 2, heat sink plates 3, a low-voltage bushing 4, and a high-voltage bushing 5. The two heat sinks 2 are respectively installed on the front and rear side walls of the transformer body 1. The heat sink plates 3 are installed at equal intervals on the inner wall of the heat sink 2. The low-voltage bushing 4 and the high-voltage bushing 5 are both fixedly installed on the top of the transformer body 1. A mounting shell 6 is fixedly connected to one side wall of the heat sink 2.
[0035] Furthermore, a weak wind energy storage component 7 is provided inside the mounting housing 6. A rotating ring 702 is rotatably connected to the outer wall of the energy storage shaft 701, and a torsion spring 703 is fixedly connected to the inner wall of the rotating ring 702. The other end of the torsion spring 703 is fixedly connected to the outer wall of the energy storage shaft 701. A support rod 704 is symmetrically fixedly connected to the outer wall of the rotating ring 702. A sliding groove 705 is opened on the inner wall of the front and rear sides of the mounting housing 6 corresponding to the support rod 704, and the outer wall of the support rod 704 slides in contact with the inner wall of the sliding groove 705. A transmission gear 706 is fixedly connected to both ends of the energy storage shaft 701. A rotating rod 10 is rotatably connected to the top of the mounting housing 6, and the bottom of the rotating rod 10 is connected to the energy storage shaft 701 through another transmission gear 706. The top of the rotating rod 10 extends to the outside of the mounting housing 6, and a wind cup 11 is fixedly connected to the top of the rotating rod 10.
[0036] In this embodiment, during the operation of this intelligent large power transformer, a rotating rod 10 is rotatably connected to the top of the mounting housing 6, and the bottom of the rotating rod 10 is connected to the power storage shaft 701 via another transmission gear 706. The top of the rotating rod 10 extends to the outside of the mounting housing 6, and a wind cup 11 is fixedly connected to the top of the rotating rod 10. Thus, the rotating rod 10 can be rotated by the wind cup 11 using external wind power, thereby synchronously driving the power storage shaft 701 to rotate.
[0037] Then, in weak wind weather, due to the low wind intensity and intermittent nature of the wind, a rotating ring 702 is rotatably connected to the outer wall of the energy storage shaft 701, and a torsion spring 703 is fixedly connected to the inner wall of the rotating ring 702. The other end of the torsion spring 703 is fixedly connected to the outer wall of the energy storage shaft 701. A support rod 704 is symmetrically fixedly connected to the outer wall of the rotating ring 702. The inner walls of the front and rear sides of the mounting housing 6 are provided with grooves 705 corresponding to the support rod 704, and the outer wall of the support rod 704 slides in contact with the inner wall of the groove 705. Thus, the torsion spring 703 can store energy by utilizing its elasticity when the energy storage shaft 701 rotates.
[0038] Next, slots 707 are evenly spaced on the outer wall of the energy storage shaft 701. A mounting bracket 708 is fixedly connected to the inner left wall of the mounting housing 6, and a locking rod 709 is slidably connected to the inner right wall of the mounting bracket 708. A spring 710 is fixedly connected to the left end of the locking rod 709, and the other end of the spring 710 is fixedly connected to the inner left wall of the mounting housing 6. The locking rod 709 forms a telescopic structure with the mounting bracket 708 and the spring 710. The right end of the locking rod 709 is pressed against the inner wall of the slot 707 by the spring 710. The right end of the locking rod 709 is inclined. Thus, when the energy storage shaft 701 rotates, the rotation direction of the energy storage shaft 701 can be restricted by the cooperation of the locking rod 709 and the slot 707, so as to store the accumulated energy and prevent premature release.
[0039] Next, to visualize the degree of power accumulation so that it can be released upon completion of a single cleaning action, a second spring 711 is fixedly connected to the inner wall of the left side of the housing 6, and a slide rod 712 is fixedly connected to the other end of the spring 711. A guide rod 713 is fixedly connected to the outer wall of the slide rod 712 facing the power storage shaft 701, and a compression groove 714 is formed on the outer wall of the power storage shaft 701 corresponding to the guide rod 713. The outer wall of the guide rod 713 is slidably connected to the inner wall of the compression groove 714. Support rods 715 are fixedly connected to both ends of the slide rod 712, and a second slide groove 716 is formed on the inner walls of the front and rear sides of the housing 6 corresponding to the support rod 715. The outer wall of the support rod 715 is slidably connected to the inner wall of the slide groove 716. Thus, during the power storage process, the rotation of the power storage shaft 701 can guide the guide rod 713 downward through the spiral groove of the compression groove 714 to compress the second spring 711.
[0040] When the guide rod 713 moves downward and passes the position where the second spring 711 connects with the left inner wall of the mounting housing 6, the energy storage shaft 701 moves downward rapidly under the compression force of the second spring 711, completing the energy storage action. This drives the subsequent flipping cleaning component 9 to operate, thus enabling stable and complete cleaning of the heat sink 3 of the power transformer in weak wind conditions. This avoids interruption of operation due to weak wind. It directly drives in strong winds and stores energy to compensate in weak winds, achieving reliable operation across the entire wind speed range. This helps ensure the heat dissipation effect of the heat sink 3 and ensures the stability of the power transformer during use.
[0041] In embodiment two, based on the above embodiment, a temperature control locking component 8 is provided inside the mounting housing 6. A helical gear 802 is fixedly connected at equal distances to the transmission gear 706 on the outer wall of the transmission rod 801. An installation groove 803 is opened on the outer wall of the transmission rod 801. A pull rope 804 is fixedly connected to the inner wall of the installation groove 803. The other end of the pull rope 804 extends through the interior of the mounting housing 6 to the outside. An electric push rod 805 is fixedly installed on one side of the outer wall of the heat sink 2, corresponding to the transmission rod 801. A locking block 806 is fixedly connected to one end of the electric push rod 805. A locking groove 807 is opened on one end of the transmission rod 801 facing the locking block 806. The outer wall of the locking block 806 and the inner wall of the locking groove 807 are in contact and slide to match. A temperature sensor 808 is fixedly installed on one side of the outer wall of the heat sink 2. The temperature sensor 808 is electrically connected to the electric push rod 805.
[0042] In this embodiment, helical gears 802 are fixedly connected at equal intervals to the transmission gears 706 on the outer wall of the transmission rod 801, and an installation groove 803 is provided on the outer wall of the transmission rod 801. A pull rope 804 is fixedly connected to the inner wall of the installation groove 803, and the other end of the pull rope 804 extends from the inside of the mounting housing 6 to the outside. Thus, when the entire energy storage shaft 701 moves downward rapidly, the two helical gears 802 can mesh and match with the transmission gears 706 at the bottom of the energy storage shaft 701, causing the transmission rod 801 to rotate, thereby using the pull rope 804 for subsequent transmission.
[0043] Then, during the downward movement of the power storage shaft 701, a movable annular groove 717 is provided on the outer wall of the power storage shaft 701, and the inner wall of the movable annular groove 717 is connected to the inner wall of several slots 707. Thus, through the setting of the slots 707, during the downward movement of the power storage shaft 701, the slots 707 cooperate with the locking rod 709, allowing the locking rod 709 to slide from bottom to top within the slots 707, preserving the power storage capacity of the power storage shaft 701 as much as possible. Until the transmission gear 706 at the bottom of the power storage shaft 701 is about to contact the two helical gears 802, at this time the locking rod 709 will slide smoothly from the top of the slots 707 into the movable annular groove 717, thereby releasing the unidirectional rotation restriction on the power storage shaft 701, so that the power storage shaft 701 can stably output the required force.
[0044] Then, during the release process of the energy storage shaft 701, the energy storage shaft 701 rotates in the opposite direction, thereby driving the guide rod 713 to move upward. When the guide rod 713 moves upward and exceeds the position where the second spring 711 is connected to the left inner wall of the mounting housing 6, the energy storage shaft 701 moves upward rapidly under the compression force of the second spring 711, completing the release action and reconnecting with the rotating rod 10 to re-store energy.
[0045] Next, an electric push rod 805 is fixedly installed on one side of the outer wall of the heat sink 2, corresponding to the transmission rod 801. One end of the electric push rod 805 is fixedly connected to a locking block 806. A locking groove 807 is opened on one end of the transmission rod 801 facing the locking block 806. The outer wall of the locking block 806 and the inner wall of the locking groove 807 are fitted and slidably matched. A temperature sensor 808 is fixedly installed on one side of the outer wall of the heat sink 2. The temperature sensor 808 is electrically connected to the electric push rod 805, so that the temperature of the heat sink 3 can be monitored by the temperature sensor 808. By using the cooperation of the locking block 806 and the locking groove 807, the lock is unlocked only when the temperature of the heat sink 3 is higher than the normal value due to dust or other factors. This allows the locking block 806 to disengage from the locking groove 807, avoiding additional wear caused by ineffective cleaning at normal temperature and ensuring the service life of the coating of the heat sink 3 of the power transformer.
[0046] Then, when the locking block 806 and the locking groove 807 are in the connected state, that is, when the heat sink 3 is at normal temperature, the energy storage shaft 701 can still store energy normally. After the energy storage is completed and it moves down to mesh with the helical gear 802, the energy stored in the energy storage shaft 701 can be preserved by the transmission rod 801, which cannot rotate at this time. This allows for timely cleaning of the overheated heat sink 3 when the heat sink 3 of the power transformer is covered with a lot of dust and the temperature rises, thus achieving targeted cleaning and ensuring the stability of the power transformer during use.
[0047] In embodiment three, based on the above embodiment, a flip cleaning component 9 is provided on one side of the outer wall of the heat sink 2. Mounting plates 901 are fixedly connected to both sides of the outer wall of the heat sink 2, and a limiting groove 902 is opened through the side wall of the mounting plate 901. A flip plate 904 is fixedly connected to the outer wall of the connecting rod 903, and a cleaning block 905 is fixedly connected at equal distances to the outer wall of the flip plate 904 corresponding to the heat sink 3. A flip gear 906 is fixedly connected to the outer walls of both ends of the connecting rod 903. A toothed plate 907 is fixedly connected to the outer wall of the two mounting plates 901 on the side away from each other, corresponding to the flip gear 906. The outer wall of one side of the flip gear 906 meshes with the toothed plate 907. An auxiliary plate 908 is fixedly connected to the outer walls of both ends of the connecting rod 903. An auxiliary frame 909 is fixedly connected to the front and rear side walls of the two mounting plates 901 corresponding to the auxiliary plate 908.
[0048] In this embodiment, under normal circumstances, mounting plates 901 are fixedly connected to both outer walls of the heat sink 2, and a limiting groove 902 is opened through the side wall of the mounting plate 901. A flip plate 904 is fixedly connected to the outer wall of the connecting rod 903, and a cleaning block 905 is fixedly connected to the outer wall of the flip plate 904 at equal distances from the heat sink 3. At this time, the flip plate 904 does not contact or block the heat sink 3. When the transmission rod 801 rotates, the pull rope 804 is wound up. At this time, the outer wall of the connecting rod 903 is slidably connected to the inner wall of the limiting groove 902. The left and right side walls of the flip plate 904 are slidably connected to the outer wall of the two mounting plates 901 on the side that is close to each other. The other extended end of the pull rope 804 is sleeved on the outer wall of the left end of the connecting rod 903, so that the pull rope 804 can drive the flip plate 904 to rise.
[0049] Then, during the initial ascent, a reversing gear 906 is fixedly connected to the outer walls of both ends of the connecting rod 903. A toothed plate 907 is fixedly connected to the outer wall of the two mounting plates 901 on the opposite side, corresponding to the reversing gear 906. The outer wall of the reversing gear 906 meshes with the toothed plate 907, so that the reversing plate 904 can rotate 180 degrees by utilizing the cooperation between the reversing gear 906 and the toothed plate 907.
[0050] Next, auxiliary plates 908 are fixedly connected to the outer walls of both ends of the connecting rod 903. Auxiliary frames 909 are fixedly connected to the front and rear side walls of the two mounting plates 901 corresponding to the auxiliary plates 908. The side wall of the two auxiliary frames 909 on the same side that is close to each other has a limiting groove 910 corresponding to the auxiliary plate 908. The bottom of the auxiliary frame 909 is inclined to the auxiliary plate 908. So when the connecting rod 903 rotates 180 degrees, it will synchronously drive the auxiliary plate 908 to flip from facing down to facing up. At this time, the limiting groove 910 of the two auxiliary frames 909 on the same side will be used to fix the auxiliary plate. 908 provides support and restriction to ensure that the cleaning block 905 on the surface of the flip plate 904 can be stably delivered between the heat sink 3 for cleaning during the rising and falling process. This achieves the effect of storage when cleaning is not required, ensuring that the airflow channel remains intact and avoiding the occupation of the heat dissipation space between the heat sink 3, which would affect heat dissipation. At the same time, during cleaning, the falling and flipping back method can shake the cleaned dust away from the heat dissipation area by flipping, preventing dust from falling back after cleaning, ensuring the heat dissipation effect of the transformer after cleaning, and improving its service life.
[0051] The working principle of this invention is as follows: During the operation of this intelligent large power transformer, the wind cup 11 drives the rotating rod 10 to rotate by the external wind force, which in turn drives the energy storage shaft 701 to rotate synchronously. In weak wind weather, due to the low wind intensity and intermittent nature of the wind, the torsion spring 703 is set to store energy by utilizing the elastic force of the torsion spring 703 when the energy storage shaft 701 rotates.
[0052] Then, when the energy storage shaft 701 rotates, the rotation direction of the energy storage shaft 701 can be restricted by the cooperation of the locking rod 709 and the locking groove 707, so as to store the energy storage force and avoid premature release. During the energy storage process, the rotation of the energy storage shaft 701 can guide the guide rod 713 downward by the spiral groove of the compression groove 714 to compress the second spring 711.
[0053] Then, when the guide rod 713 moves downward and passes the position where the second spring 711 connects with the left inner wall of the mounting housing 6, the energy storage shaft 701 moves downward rapidly under the compression force of the second spring 711, completing the energy storage action, so as to drive the subsequent flipping cleaning component 9 to operate. In this way, even in weak wind conditions, the heat sink 3 of the power transformer can be cleaned stably and completely, avoiding interruption of operation due to weak wind. It can be directly driven in strong winds and compensated by energy storage in weak winds, achieving reliable operation across the entire wind speed range. This helps to ensure the heat dissipation effect of the heat sink 3 and ensures the stability of the power transformer during use.
[0054] Then, during the downward movement of the power storage shaft 701, the cooperation between the slot 707 and the lever 709 allows the lever 709 to slide from bottom to top within the slot 707, preserving the power storage capacity of the power storage shaft 701 as much as possible. When the transmission gear 706 at the bottom of the power storage shaft 701 is about to contact the two helical gears 802, the lever 709 will slide smoothly from the top of the slot 707 into the movable ring groove 717, thereby releasing the unidirectional rotation restriction on the power storage shaft 701 and enabling the power storage shaft 701 to stably output the required force.
[0055] Next, during the release process of the energy storage shaft 701, the energy storage shaft 701 rotates in the opposite direction, thereby driving the guide rod 713 to move upward. When the guide rod 713 moves upward and exceeds the position where the second spring 711 connects with the left inner wall of the mounting housing 6, the energy storage shaft 701 moves upward rapidly under the compression force of the second spring 711, completing the release action and reconnecting with the rotating rod 10 to re-store energy. At the same time, the temperature of the heat sink 3 is monitored by the temperature sensor 808. With the cooperation of the locking block 806 and the locking groove 807, the lock is unlocked only when the temperature of the heat sink 3 is higher than the normal value due to dust or other factors. This allows the locking block 806 to disengage from the locking groove 807, avoiding additional wear caused by ineffective cleaning at normal temperature and ensuring the service life of the coating of the heat sink 3 of the power transformer.
[0056] Then, when the locking block 806 and the locking groove 807 are in the connected state, that is, when the heat sink 3 is at normal temperature, the energy storage shaft 701 can still store energy normally. After the energy storage is completed and it moves down to mesh with the helical gear 802, the energy stored in the energy storage shaft 701 can be preserved by the transmission rod 801, which cannot rotate at this time. This allows for timely cleaning of the overheated heat sink 3 when the heat sink 3 of the power transformer is covered with a lot of dust and the temperature rises, thus achieving targeted cleaning and ensuring the stability of the power transformer during use.
[0057] Next, when the transmission rod 801 rotates, it winds up the pull rope 804, causing the flip plate 904 to rise. During the initial rise, the flip gear 906 and the toothed plate 907 work together to make the flip plate 904 rotate 180 degrees. When the connecting rod 903 rotates 180 degrees, it will simultaneously drive the auxiliary plate 908 to flip from downward to upward. At this time, the auxiliary plate 908 will be supported and restricted by the limiting grooves 910 of the two auxiliary frames 909 on the same side, ensuring that the cleaning block 905 on the surface of the flip plate 904 can be stably sent into the space between the heat sink 3 for cleaning during the rise and fall. This achieves the effect of storage when cleaning is not required, ensuring that the airflow channel remains intact and avoiding the occupation of the heat dissipation space between the heat sink 3, which would affect heat dissipation. At the same time, during cleaning, the dust can be thrown away from the heat dissipation area by flipping during the fall, preventing dust from falling back after cleaning, ensuring the heat dissipation effect of the transformer after cleaning and improving its service life.
