Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a marine transformer device. Background Technology

[0002] Marine dry-type transformers are an indispensable and important piece of equipment in ship power systems. During ship operation, they are affected by the humid air in the cabin and the intrusion of ambient dust. At the same time, the long-term wear and tear of the transformer's internal iron core, windings, and fastening metal components will generate metal debris. Dust and metal debris mix and clump together, gradually accumulating at the bottom of the transformer tank. Accumulated impurities can block the heat dissipation ducts at the bottom of the equipment, reducing the transformer's heat dissipation efficiency and insulation performance. In severe cases, it can easily cause local overheating, insulation damage, and safety hazards. It is necessary to clean the accumulated impurities regularly.

[0003] When cleaning the deposits at the bottom of existing marine dry-type transformers, it is generally necessary to shut down the transformer, disassemble the equipment casing, and have operators enter the tank for cleaning. This process is not only complex and time-consuming, affecting normal ship operations, but also presents certain safety risks due to the cramped working space and poor working environment inside the tank. In addition, the existing structure makes it difficult for operators to visually observe the accumulation of dust and debris at the bottom of the tank from the outside, making it difficult to arrange cleaning operations in a timely manner and failing to meet actual usage requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a marine transformer device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine transformer device, comprising a transformer housing for installing a marine dry-type transformer, wherein a slag discharge port is provided at the bottom of the transformer housing; a lifting assembly installed on one side of the bottom of the transformer housing, and a support assembly provided on the other side of the bottom of the transformer housing; a display assembly fixed to the outside of the slag discharge port, wherein a fixing assembly is installed on the outside of the display assembly, and the display assembly is detachably connected to the bottom of the transformer housing through the fixing assembly; and a slag discharge assembly fixed to the bottom of the transformer housing, wherein the slag discharge assembly is used to push dust and metal debris deposited at the bottom of the transformer housing.

[0006] Preferably, the lifting assembly includes a hydraulic jack located at the bottom left side of the transformer housing, the telescopic end of the hydraulic jack being rotatably connected to a connecting seat, and the connecting seat being fixedly connected to the bottom of the transformer housing.

[0007] Preferably, the support assembly includes a rotating block fixed to the bottom right side of the transformer housing, with limit shafts fixed at both ends of the rotating block, a U-shaped seat rotatably connected to the outer side of the limit shaft, a support frame fixed to the bottom of the U-shaped seat, and fixed foot plates fixed to the bottom of both the support frame and the hydraulic jack.

[0008] Preferably, the display component includes an annular positioning plate, which is coaxially distributed with the slag discharge port. A transparent display plate is fixed to the inner side of the annular positioning plate, and the thickness of the transparent display plate is less than the thickness of the annular positioning plate. A sealing ring is fixed to the side of the annular positioning plate near the transformer housing, and the sealing ring abuts against the bottom of the transformer housing.

[0009] Preferably, the fixing assembly includes an external gear ring rotatably connected to the bottom of the transformer housing. Four sets of gears are meshed on the outer side of the external gear ring. A threaded cylinder is fixedly sleeved in the central hole of each gear. A threaded column is threadedly connected to the threaded cylinder. The threaded cylinder is rotatably connected to the bottom of the transformer housing. A clamping plate is fixed at the end of the threaded column away from the transformer housing. The upper side of the clamping plate presses against the outer side of the annular positioning plate. A linkage is connected between two of the threaded cylinders and the corresponding limiting shaft.

[0010] Preferably, the linkage includes a rotating arm that is fixedly sleeved with the limiting shaft, an arc-shaped rack is fixed at one end of the rotating arm, a second gear meshes with one side of the arc-shaped rack, a bevel gear set is driven to one side of the second gear, and a pulley set is driven to the threaded cylinder and the bevel gear set.

[0011] Preferably, the slag removal assembly includes two sliding rods symmetrically fixed on the inner wall of the transformer tank. Each sliding rod has an iron ball slidably sleeved on its outer side. The bottom of the iron ball has a groove, and a spring is fixed in the groove. A connecting plate is fixed to the end of the spring away from the iron ball. Two scrapers arranged back to back are fixed to the bottom of the connecting plate. The bottom of the scrapers is in contact with the inner bottom of the transformer tank.

[0012] Preferably, one end of the abutment plate is slidably sleeved with a limit rod, and the limit rod is fixed to the bottom of the transformer housing.

[0013] Preferably, the side of the abutment plate that contacts the annular positioning plate is provided with an anti-slip rubber pad, and the anti-slip rubber pad is fixedly bonded to the abutment plate.

[0014] Preferably, an inclined plate is installed on the inner wall of the support frame, and a monitoring probe is also installed on one side of the inclined plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention allows operators to directly observe the accumulation of dust and metal debris at the bottom of the transformer tank from the outside of the tank via a display component fixed to the outside of the slag discharge port. This enables them to promptly grasp the impurity situation without opening the tank, rationally arrange dust removal and maintenance time, and avoid blind operation. Furthermore, when the ship is sailing and swaying with the water flow, the slag discharge component can move synchronously, automatically pushing the dust and metal debris that fall to the bottom of the transformer tank to the display component for accumulation. This makes it easier for staff to determine the timing of dust removal and maintenance of the dry-type transformer based on the accumulation amount.

[0016] When it is necessary to clean deposited impurities, this invention lifts one side of the transformer tank using a lifting component, causing the transformer tank to tilt with the rotating part of the support component as the fulcrum. The dust accumulated at the bottom of the tank slides and collects towards the slag discharge port due to its own weight. At the same time, the linkage component drives the fixing component to work, so that the clamping plate automatically releases the locking and fixing of the display component, making it easy to quickly remove the display component and clean up the accumulated impurities. The entire process does not require disassembly and cleaning of the tank, simplifying the maintenance process. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 10 The diagram shows a marine dry-type transformer assembly, including a transformer housing 1 for mounting the marine dry-type transformer, with a slag discharge port 2 at the bottom of the transformer housing 1; a lifting assembly 3 installed on one side of the bottom of the transformer housing 1, and a support assembly 4 on the other side of the bottom of the transformer housing 1; a display assembly 5 fixed to the outside of the slag discharge port 2, with a fixing assembly 6 installed on the outside of the display assembly 5, and the display assembly 5 is detachably connected to the bottom of the transformer housing 1 via the fixing assembly 6; and a slag discharge assembly 7 fixed to the bottom of the transformer housing 1, which is used to push away dust and metal debris deposited at the bottom of the transformer housing 1.

[0021] The display component 5 includes an annular positioning plate 15, which is coaxially distributed with the slag discharge port 2. A transparent display plate 16 is fixed on the inner side of the annular positioning plate 15. The thickness of the transparent display plate is less than the thickness of the annular positioning plate. A sealing ring 17 is fixed on the side of the annular positioning plate close to the transformer box, and the sealing ring 17 is pressed against the bottom of the transformer box.

[0022] In this solution, the transparent display panel 16 allows operators to directly observe the accumulation of dust and metal debris at the bottom of the transformer box from the outside of the box. This allows them to grasp the state of impurities in a timely manner without opening the box, facilitating the reasonable scheduling of dust removal and maintenance time and avoiding blind operation. During the ship's navigation, when the hull sways with the water flow, the slag discharge component 7 can automatically complete the sweeping action, automatically pushing the dust and debris deposited at the bottom of the transformer box 1 to the transparent display panel 16 at the slag discharge port 2. After the impurities accumulate at the transparent display panel 16, it is convenient for the staff to intuitively judge the degree of slag accumulation and promptly arrange the dust removal and maintenance work of the dry-type transformer.

[0023] It should be noted that the transparent display panel 16 is made of high-strength transparent polycarbonate material, which has strong light transmittance and impact resistance. It is suitable for the humid and dusty working conditions of ship cabins, is not easy to crack or break, and can stably meet the long-term use needs under complex marine working conditions.

[0024] Furthermore, the lifting assembly 3 includes a hydraulic jack 8 located at the bottom left side of the transformer housing 1. The telescopic end of the hydraulic jack 8 is rotatably connected to a connecting seat 9, which is fixedly connected to the bottom of the transformer housing 1.

[0025] The support assembly 4 includes a rotating block 10 fixed to the bottom right side of the transformer housing 1. Both ends of the rotating block 10 are fixed with limit shafts 11. A U-shaped seat 12 is rotatably connected to the outside of the limit shafts 11. A support frame 13 is fixed to the bottom of the U-shaped seat 12. Both the support frame 13 and the bottom of the hydraulic jack 8 are fixed with foot plates 14.

[0026] In this solution, when it is necessary to clean the deposited impurities, the transformer is shut down. Then, the operator uses a pry bar to operate the hydraulic jack 8. The telescopic end of the hydraulic jack 8 will slowly lift one side of the transformer tank 1. The transformer tank 1 will tilt at the fulcrum of the rotating connection of the support component, with the tilt angle varying between 0-10°. In this tilted state, the dust and debris at the bottom of the tank will slide down to the slag discharge port under its own weight due to the inclined surface of the tank. At the same time, during the tilting process of the transformer tank 1, the limiting shaft 11 of the support component 4 will rotate synchronously with the rotation of the transformer tank 1, which will also drive the fixing component 6 to work, automatically releasing the locking plate 22 from the display component 5. Without the operator having to tighten the fasteners one by one, the display component 5 can be quickly removed from the slag discharge port 2, completing the impurity cleaning operation. The entire cleaning process does not require the operator to enter the tank, which greatly reduces the safety risk of the cleaning operation, shortens the operation time, and reduces the impact on the normal operation of the ship.

[0027] It should be noted that, through the setting of lifting component 3 and support component 4, all dust and debris inside the box can be discharged from the slag discharge port 2 along the inclined bottom of the box. With the pushing action of slag discharge component 7, the impurities at the bottom of the box can be thoroughly cleaned, and the cleaning effect is better. Moreover, the whole operation can be completed only from the outside, and the process is simple and convenient.

[0028] Furthermore, the slag removal assembly 7 includes two sliding rods 29 symmetrically fixed on the inner wall of the transformer housing 1. Each sliding rod 29 has an iron ball 30 slidably sleeved on its outer side. The bottom of the iron ball 30 has a groove, and a spring 31 is fixed in the groove. A connecting plate 32 is fixed to the end of the spring 31 away from the iron ball 30. Two scrapers 33 arranged back to back are fixed to the bottom of the connecting plate 32. The bottom of the scrapers 33 is in contact with the inner bottom of the transformer housing 1.

[0029] It should be noted that, through the setting of the slag discharge component 7, the iron ball 30 can slide back and forth along the slide bar 29 as the ship sways during navigation, driving the scraper 33 at the bottom to continuously scrape the inner bottom of the transformer tank 1, automatically pushing the dust and metal debris deposited on the inner bottom to the slag discharge port 2. Automatic slag accumulation can be completed without additional power. After the impurities are pushed to the slag discharge port 2, they accumulate on the inside of the transparent display plate 16, making it convenient for operators to intuitively observe the amount of slag accumulation. At the same time, the spring 31 can elastically press the scraper 33 against the inner bottom of the tank, ensuring that the scraper 33 is always in contact with the bottom of the tank, improving the effect of scraping and slag accumulation, avoiding scraping gaps caused by wear of the scraper 33, and ensuring the stability of the scraping and slag accumulation.

[0030] The principle of automatic collection of impurities at the bottom of the transformer tank 1 is as follows: When the hull tilts due to the water flow, the iron ball 30 slides along the tilted slide bar 29 under its own weight. When the two iron balls 30 move synchronously, they drive the connecting plate 32 and the scraper 33 to move synchronously. During the movement, the scraper 33 directly pushes and scrapes the bottom of the tank, pushing the dust and metal debris deposited there to the slag discharge port 2 area. When the hull tilts in the opposite direction, the iron ball 30 slides in the opposite direction along the slide bar 29, driving the scraper 33 to scrape and push in the opposite direction. Since the two scrapers 33 are set back to back, no matter which direction the iron ball 30 moves, there will always be one scraper 33 that can push the impurities at the bottom of the tank towards the slag discharge port 2. With the help of the spring 31, the scraper 33 is continuously pressed against the bottom of the tank, ensuring that the impurities are effectively pushed with each scraping motion, automatically completing the collection and accumulation of impurities, which is convenient for operators to observe and clean later.

[0031] Example 2: This embodiment further explains Example 1. The difference is that the installation method of the display component 5 is optimized, so that the disassembly and assembly of the display component 5 can be automatically linked and unlocked as the cabinet is tilted, further simplifying the cleaning and disassembly process.

[0032] Specifically, the fixing component 6 includes an external gear ring 18 rotatably connected to the bottom of the transformer housing 1. Four sets of gears 19 are meshed on the outer side of the external gear ring 18. A threaded cylinder 20 is fixedly sleeved in the central hole of each gear 19. A threaded column 21 is threadedly connected to the inner thread of the threaded cylinder 20. The threaded cylinder 20 is rotatably connected to the bottom of the transformer housing 1. A clamping plate 22 is fixed at the end of the threaded column 21 away from the transformer housing 1. The upper side of the clamping plate 22 is pressed against the outer side of the annular positioning plate 15. A linkage 23 is connected between two threaded cylinders 20 and the corresponding limiting shaft 11.

[0033] The principle of automatic linkage unlocking: When the transformer tank 1 is tilted by the hydraulic jack 8, the transformer tank 1 rotates relative to the U-shaped seat 12 around the rotation point of the U-shaped seat 12 and the limit shaft 11. This will drive the limit shaft 11 to rotate synchronously. After the limit shaft 11 rotates, it will drive the linkage 23 to move, which in turn will drive the corresponding two threaded cylinders 20 to rotate synchronously. After the threaded cylinders 20 rotate, they will drive the other two threaded cylinders 20 to rotate synchronously through the meshing transmission of the external gear ring 18 and the gear 19. When the four threaded cylinders 20 rotate synchronously, they will drive the corresponding threaded column 21 to move outward through the thread transmission, which will drive the four clamping plates 22 to move away from the annular positioning plate 15 synchronously, automatically releasing the clamping and locking of the annular positioning plate 15. The operator can directly remove the display component 5 to clean the accumulated residue without additional operation of the fasteners, which greatly simplifies the operation steps of the cleaning operation.

[0034] The linkage 23 includes a rotating arm 24 that is fixedly sleeved with the limiting shaft 11. One end of the rotating arm 24 is fixed with an arc-shaped rack 25. A gear 26 meshes with one side of the arc-shaped rack 25. A bevel gear set 27 is connected to one side of the gear 26. A pulley set 28 is connected between the threaded cylinder 20 and the bevel gear set 27.

[0035] In this scheme, the limit shaft 11 rotates with the transformer housing 1, which in turn drives the rotating arm 24 to rotate synchronously. The rotating arm 24 drives the arc rack 25 to move. The arc rack 25 meshes with and drives the gear 26 to rotate. The gear 26 changes the transmission direction through the bevel gear set 27, and then drives the corresponding threaded cylinder 20 to rotate through the pulley set 28. After the threaded cylinder 20 rotates, it drives the threaded column 21 to move outward through the threaded transmission, which in turn drives the clamping plate 22 to move outward, automatically disengaging from the clamping lock of the annular positioning plate 15, so that the annular positioning plate 15 and the transparent display plate 16 can be directly removed from the slag discharge port 2.

[0036] It should be noted that by using the fixed component 6, the rotation generated by the support component 4 when the transformer housing 1 is lifted and tilted serves as the unlocking power. This eliminates the need for additional electric drive components, resulting in a more compact and rational structural design, lower cost, and stable and reliable transmission, reducing the likelihood of jamming or failure. Furthermore, the meshing transmission of multiple gears and the external gear ring 18 ensures that all the clamping plates 22 move synchronously, guaranteeing consistent locking and unlocking actions and preventing any clamping plates 22 from becoming stuck and unable to move.

[0037] It should also be noted that the bevel gear set 27 consists of a pair of meshing bevel gears, in which the driving bevel gear and the second gear 26 are coaxially fixed. The pulley set 28 consists of a driving pulley and a driven pulley. The driving pulley is coaxially fixed with the driven bevel gear, and the driven pulley is coaxially fixed with the corresponding threaded cylinder 20. The two pulleys are connected by a belt to complete the switching of transmission direction and the stable transmission of power, ensuring that the rotation of the limit shaft 11 can be stably and synchronously transmitted to the threaded cylinder 20, and ensuring the stability and reliability of the unlocking action.

[0038] In addition, a limiting rod 34 is slidably sleeved at one end of the abutment plate 22. The limiting rod 34 is fixed to the bottom of the transformer housing 1. The limiting rod 34 guides and limits the movement of the abutment plate 22, preventing the abutment plate 22 from rotating with the threaded column 21. An anti-slip rubber pad 35 is provided on the side of the abutment plate 22 that contacts the annular positioning plate 15. The anti-slip rubber pad 35 is fixedly bonded to the abutment plate 22. The anti-slip rubber pad 35 can increase the friction between the abutment plate 22 and the annular positioning plate 15, improve the dustproof sealing effect in the locked state, prevent the abutment plate 22 from loosening during navigation and prevent dust from entering from the gaps, ensure the firmness of the installation of the display component 5, and also buffer the vibration of the annular positioning plate 15, extending the service life of the transparent display plate 16 and the annular positioning plate 15.

[0039] Example 3: This embodiment further explains Example 1, the difference being that the observation method of the display component 5 is optimized, so that staff can directly monitor the slag accumulation remotely without the need for on-site manual inspection.

[0040] The display component 5 includes an annular positioning plate 15, which is coaxially distributed with the slag discharge port 2. A transparent display plate 16 is fixed on the inner side of the annular positioning plate 15. The thickness of the transparent display plate 16 is less than the thickness of the annular positioning plate 15. A sealing ring 17 is fixed on the side of the annular positioning plate 15 near the transformer housing 1, and the sealing ring 17 is pressed against the bottom of the transformer housing 1. An inclined plate 36 is installed on the inner wall of the support frame 13, and a monitoring probe 37 is also installed on one side of the inclined plate 36.

[0041] It should be noted that the monitoring probe 37 is positioned facing the transparent display panel 16, which can collect real-time images of the dust and metal debris accumulated on the inside of the transparent display panel 16 and transmit the collected image signals to the ship's central control system. The staff can intuitively observe the status of the slag accumulation in the central control room without having to go to the equipment installation site to check one by one. This is especially suitable for scenarios where multiple transformers are centrally located, which can greatly reduce the workload of daily inspections and improve inspection efficiency.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
