Description

Technical Field

[0001] This invention relates to the field of transformer heat dissipation technology, and specifically discloses an auxiliary heat dissipation device for dustproof transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for voltage step-up / step-down, impedance matching, and safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electromotive force is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the number of magnetic fluxes linked to the coil changes; this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

[0003] When existing transformers are used outdoors, they will generate a lot of heat. It is difficult to dissipate the heat effectively from the transformer body using only the heat dissipation slots. In addition, due to airflow issues, a lot of dust will adhere to the surface of the heat dissipation slots. If they are not cleaned for a long time, it will affect the heat dissipation effect. Therefore, we need to improve them. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a dustproof transformer auxiliary heat dissipation device.

[0005] To achieve the above objectives, the present invention provides an auxiliary heat dissipation device for a dustproof transformer, comprising a dustproof box and a transformer body connected inside the dustproof box via an installation assembly. A top box is connected to the top of the dustproof box, and ventilation mechanisms are provided on the inner sides of both ends of the top box. A partition is installed in the middle of the top of the top box. Filters are installed inside both sides of the dustproof box. Dust-sweeping components are provided on the inner walls of both sides of the dustproof box, near the upper part of the filter screens. A bottom box is connected to the bottom of the dustproof box, and a heat-conducting mechanism is provided inside the bottom box. A movable door is rotatably installed on the front end of the dustproof box.

[0006] Preferably, the installation assembly includes recycling bins that are respectively fixedly connected to the outer walls of both sides of the transformer body and located near the bottom. Each of the two recycling bins is provided with a dust collection component on its inner side. Each of the two recycling bins has a fixing seat extending from one end of its outer wall toward the side that is close to each other. The inner side of each of the two fixing seats is fixedly connected to the dustproof box by a threaded bolt.

[0007] Preferably, the dust collection component includes a recycling box that is correspondingly and movably mounted inside the recycling bin. A pull rod is fixedly connected to the outer wall of one end of the recycling box, and the recycling box is located below the filter screen.

[0008] Preferably, the ventilation mechanism includes cooling fans that are both located on one side of the top box. The two sides of the cooling fans are respectively connected to the inner wall of the top box through fixed mounting brackets, and the cooling fans are arranged at an angle.

[0009] Preferably, the dust removal assembly includes connecting columns installed on the inner wall of one side of the dustproof box and near the filter screen. A connecting plate is rotatably fitted on the outer side of the connecting column. A U-shaped frame is movably fitted on the inner side of the connecting plate and near the lower position of the connecting column. A wiping plate is fixedly connected to the outer wall of one end of the U-shaped frame. The wiping plate slides against the surface of one side of the filter screen. A fixing member is provided on the rear end face of the connecting plate. A vertical rod is installed on the upper surface of one end of the connecting plate near the edge.

[0010] Preferably, the fastener includes a fixing plate fixedly installed on the rear end face of the connecting piece, a locking pin is slidably inserted into the middle of the inner side of the fixing plate, and a locking hole is opened on the inner side of the U-shaped frame corresponding to the position of the locking pin, and the bottom end of the locking pin is locked into the inner side of the locking hole.

[0011] Preferably, the heat conduction mechanism includes arc-shaped heat sinks that are installed at equal intervals along the horizontal direction inside the bottom box. A condenser tube is provided inside the multiple sets of arc-shaped heat sinks. The condenser tube is arranged in multiple bends and passes through the multiple sets of arc-shaped heat sinks in sequence. Both ends of the condenser tube extend to the outside of the bottom box and are connected to a joint.

[0012] Preferably, the top box is provided with wind guides on both sides centered on the partition. Each wind guide includes a bracket fixedly connected to the top wall of one side of the top box. A rotating shaft is rotatably installed inside the bracket. A connecting sleeve is fixedly fitted on the outside of the rotating shaft. Fan blades are installed at equal intervals along the circumferential direction on the outside of the connecting sleeve. Multiple sets of fan blades are located below one side of the cooling fan. A fixing rod is fixedly fitted on the outside of the rotating shaft and near the bottom of the multiple sets of fan blades. Brush heads are installed at equal intervals along the horizontal direction at the bottom of the fixing rod. The bottom of the multiple sets of brush heads slides against the top of the transformer body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The top box is equipped with a ventilation mechanism that delivers air from both ends diagonally upwards to the inside of the protective box, thereby removing the heat emitted by the transformer body. When the cooling fan is working, the airflow directly contacts multiple sets of fan blades located on one side below. These fan blades drive the rotating shaft to rotate, which in turn drives a fixed rod and multiple brush heads to rotate, cleaning the dust from the surface of the transformer body at the top. Simultaneously, as the fixed rod moves in a circular trajectory, it intermittently contacts the corresponding upright at one end. The upright, pushed by the contact of the fixed rod, causes the connecting plate, U-shaped frame, and wiping plate below to swing on the outer surface of the filter screen, thus cleaning the filter screen surface and reducing dust accumulation.

[0015] 2. By setting up a bottom box and installing multiple sets of arc-shaped heat sinks inside the bottom box, as well as condenser tubes that pass through the multiple sets of arc-shaped heat sinks, the heat at the bottom of the transformer body can be absorbed, so that when the transformer body is installed inside the dustproof box, the whole body can achieve a full heat dissipation effect, thereby improving the service life of the transformer body.

[0016] 3. The dust collection component can collect the dust scraped off the filter surface, preventing dust from accumulating inside the dust box and affecting its use. Attached Figure Description

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-7 The dustproof transformer auxiliary heat dissipation device shown includes a dustproof box 1 and a transformer body 7 connected inside the dustproof box 1 by an installation component. A top box 3 is installed on the top of the dustproof box 1. Ventilation mechanisms are provided on the inner sides of both ends of the top box 3. A partition 8 is installed in the middle of the top of the top box 3. Filter screens 2 are installed inside both sides of the dustproof box 1. Dust removal components are provided on the inner walls of both sides of the dustproof box 1 near the upper part of the filter screens 2. A bottom box 5 is connected to the bottom of the dustproof box 1. A heat conduction mechanism is provided inside the bottom box 5. A movable door 4 is rotatably installed on the front end of the dustproof box 1.

[0028] Users can access the dust box 1 by opening the movable door 4. First, the transformer body 7 is installed inside the dust box 1 by installing the assembly. This ensures that the dust box 1 can separate dust from the outside when used outdoors, ensuring the use of the transformer body 7. The filter 2 allows for internal ventilation while preventing dust from falling in.

[0029] The installation components include recycling bins 18 that are fixedly connected to the outer walls of both sides of the transformer body 7 and are located near the bottom. Dust collection components are provided inside the two recycling bins 18. A fixing seat 14 extends from one end of the outer wall of each recycling bin 18 toward the side that is close to each other. The inner sides of the two fixing seats 14 are fixedly connected to the dustproof box 1 by threaded fixing bolts 15.

[0030] The recycling bin 18 and the fixing base 14 facilitate the installation of the transformer body 7 into the dustproof box 1, and also allow the dust collection components to be installed inside the dustproof box 1 for use.

[0031] The dust collection component includes a recycling box 17 that is correspondingly and movable and installed inside the recycling bin 18. A pull rod 16 is fixedly connected to the outer wall of one end of the recycling box 17. The recycling box 17 is located below the filter screen 2.

[0032] The lever 16 can pull the recycling box 17 out from the inside of the recycling chamber 18, and then collect and process the dust scraped off by the filter screen 2.

[0033] The ventilation mechanism includes cooling fans 11, which are all located on one side of the top box 3. The two sides of the cooling fans 11 are connected to the inner wall of the top box 3 through fixed mounting bases 10. The cooling fans 11 are set at an angle.

[0034] The top box 3 is equipped with wind guides on both sides with the partition 8 as the center. The wind guides include a bracket 22 fixedly connected to the top wall of one side of the top box 3. A rotating shaft 20 is rotatably installed inside the bracket 22. A connecting sleeve 23 is fixedly fitted on the outside of the rotating shaft 20. Fan blades 21 are installed at equal intervals along the circumferential direction on the outside of the connecting sleeve 23. Multiple sets of fan blades 21 are located below one side of the cooling fan 11. A fixing rod 19 is fixedly fitted on the outside of the rotating shaft 20 and near the bottom of the multiple sets of fan blades 21. Brush heads 26 are installed at equal intervals along the horizontal direction at the bottom of the fixing rod 19. The bottom of the multiple sets of brush heads 26 slides and fits against the top of the transformer body 7.

[0035] Mounting bracket 10 can stably install cooling fan 11 inside top box 3. After the cooling fan 11 is connected to external power, it can blow airflow from above one end of dustproof box 1 and near the corner, so as to contact the multiple sets of fan blades 21 on the lower side. When the multiple sets of fan blades 21 are impacted by the airflow, they will drive the rotating shaft 20 to rotate inside the card holder 22. As a result, the fixing rod 19 on the lower side of the rotating shaft 20 can drive the multiple sets of brush heads 26 to clean the dust on the upper surface of the transformer body 7.

[0036] The dust removal assembly includes connecting posts 25 installed on the inner wall of one side of the dust box 1 and above the filter screen 2. A connecting plate 9 is rotatably fitted on the outer side of the connecting post 25. A U-shaped frame 30 is movably fitted on the inner side of the connecting plate 9 and below the connecting post 25. A wiping plate 29 is fixedly connected to the outer wall of one end of the U-shaped frame 30. The wiping plate 29 slides and fits against the surface of one side of the filter screen 2. A fixing member is provided on the rear end face of the connecting plate 9. A vertical rod 24 is installed on the upper surface of one end of the connecting plate 9 and near the edge.

[0037] The connecting post 25 allows the connecting piece 9 and the wiping plate 29 to swing on the surface of the filter screen 2 when the connecting piece 9 is moved and contacted by the fixing rod 19. The upright rod 24 can intermittently contact the fixing rod 19 during its circumferential movement, thereby ensuring that the connecting piece 9 and the wiping plate 29 can slide and adhere to the surface of the filter screen 2 repeatedly, thus ensuring the cleaning effect.

[0038] The fastener includes a fixing plate 28 fixedly installed on the rear end face of the connecting piece 9. A locking pin 27 is slidably inserted into the middle of the inner side of the fixing plate 28. A locking hole is opened on the inner side of the U-shaped frame 30 corresponding to the position of the locking pin 27. The bottom end of the locking pin 27 is locked into the inner side of the locking hole.

[0039] The fixing plate 28 facilitates the setting of the locking pin 27 above the filter screen 2. When the U-shaped frame 30 drives the wiping plate 29 to be snapped into the inside of the connecting plate 9, the locking pin 27 will automatically fall down to lock the connecting plate 9 in place. This method also facilitates the replacement of the wiping plate 29 later, and the disassembly and assembly method is relatively convenient.

[0040] The heat conduction mechanism includes arc-shaped heat sinks 12 that are installed at equal intervals along the horizontal direction inside the bottom box 5. A condenser tube 6 is provided inside the multiple sets of arc-shaped heat sinks 12. The condenser tube 6 is arranged in multiple bends and passes through the multiple sets of arc-shaped heat sinks 12 in sequence. Both ends of the condenser tube 6 extend to the outside of the bottom box 5 and are connected to a connector 13.

[0041] The connector 13 is a flange pipe, which is used to connect to an external pipeline to supply cold water to the condenser pipe 6. This allows the cold water to come into contact with multiple sets of arc-shaped heat sinks 12 as it flows through the condenser pipe 6, carrying away the heat and improving the performance of the arc-shaped heat sinks 12.

[0042] Working principle: When using the device, the user installs the transformer body 7 into the dustproof box 1 using the fixing seats 14 and the recycling bin 18 located at the lower sides of both sides, as well as the fixing bolts 15 inserted inside the fixing seats 14. This reduces dust adhesion when used outdoors. After fixing, the transformer body 7 inside the dustproof box 1 can be cooled from the upper corners of both ends of the dustproof box 1 by the cooling fans 11 located at both ends of the top box 3. The airflow blown out by the cooling fans 11 will contact the multiple sets of fan blades 21 on one side. The multiple sets of fan blades 21 will drive the rotating shaft 20 to rotate as guided by the airflow. This causes the fixing rod 19 on the outside of the rotating shaft 20 to drive the multiple sets of brush heads 26 at the bottom to clean the dust on the upper surface of the transformer body 7. At the same time, when the fixing rod 19 moves in a circumferential direction, it will periodically contact the outer surface of the upright 24 at one end. As the upright 24 is moved by the fixing rod 19, it can drive the connecting piece 9 and the U-shaped frame 30. The wiping plate 29 is used to wipe the surface of the filter screen 2, which is installed on one side inside the dustproof box 1. The reciprocating oscillation can prevent dust from accumulating on the surface of the filter screen 2. In this way, the filter screen 2 can better and more continuously play the role of ventilation and dust isolation during use. The dust swept off by the wiping plate 29 will fall into the recycling box 17 directly below. Later, the movable door 4 can be opened and the recycling box 17 can be pulled out by holding the lever 16 to dispose of the dust. In order to further improve the heat dissipation effect, multiple sets of arc-shaped heat sinks 12 inside the bottom box 5 can absorb the heat emitted from the bottom of the transformer body 7 through the bottom of the dustproof box 1. Then, one end connector 13 of the condenser pipe 6 is connected to the cold water pipe, so that the flowing cold water comes into contact with the multiple sets of arc-shaped heat sinks 12 and absorbs the heat from the outer wall of the multiple sets of arc-shaped heat sinks 12, further improving the heat dissipation effect of the multiple sets of arc-shaped heat sinks 12. Through the above structure, the dustproof box 1 can not only play the purpose of dust prevention and heat dissipation, but also clean the surface of the filter screen 2, making it convenient and practical to use.
