Description

Technical Field

[0001] This invention belongs to the field of printing press technology, and specifically relates to a transformer protective cover for printing presses. Background Technology

[0002] A printing press can transfer text, images, and other content onto paper using ink. A transformer can change the AC voltage. A transformer is installed on a printing press to meet the voltage requirements of different electrical components, so as to facilitate the smooth operation of the printing press. When the transformer is working, it generates heat, which accumulates in the area around the transformer and the printing press, which can easily cause abnormalities or failures of the components.

[0012] Furthermore, a transmission channel three is fixedly connected to the part of the second mounting cover that is away from the first mounting cover, and an adjustment unit is assembled on the part of the third transmission channel that is away from the second mounting cover.

[0013] Furthermore, the adjustment unit includes a cover, which is assembled on the outer wall of the transmission channel three. A ring block is fixedly connected to the inner wall of the cover. A cylinder is provided on the inner wall of the cover near the ring block. A flange is fixedly connected to the side wall of the cylinder. A resonance cavity is reserved inside the cylinder.

[0014] Furthermore, the protective cover includes a shield, a holding block is slidably attached to the shield, a gripping block is fixedly connected to the portion of the holding block away from the shield, a porous partition is fixedly connected to one side of the shield adjacent to the holding block, and a protective module is fixedly connected to the inner wall surface of the shield.

[0015] Furthermore, the protection module includes a rectangular base block with a pre-drilled groove. A connecting frame is fixedly connected to the wall of the rectangular base block away from the groove, and an energy storage component is fixedly connected to the wall of the connecting frame adjacent to the rectangular base block.

[0016] The beneficial effects of this invention are:

[0017] 1. The guide block of the present invention is inclined, which causes the gaseous fluid to move along the outer wall of the elastic pad. The elastic pad captures the impurity particles in the fluid, thereby reducing the probability of impurity particles being introduced into the printing press transformer in the protective cover. This prevents the particles from touching the transformer and causing device malfunction or failure. Subsequently, the gaseous fluid drives the descaling module to rotate, so as to remove impurities and foreign objects on the protective cover, so as to prevent the large accumulation of impurities and foreign objects, which would be detrimental to the flow of fluid and the dissipation of the heat generated and accumulated during the operation of the printing press transformer.

[0018] 2. The guide cone of the present invention facilitates the convergence of gaseous fluid. The first transmission channel is horseshoe-shaped and curved. During the operation of the transformer, heat is generated and accumulated. After the transformer stops operating, the surrounding heat gradually dissipates. In addition, due to the fluctuation of external temperature difference, the installation of the horseshoe-shaped and curved transmission channel helps to alleviate the pipeline tension caused by temperature difference, regulate the internal pressure fluctuation caused by temperature difference, and enhance the stability of the descaling module during operation. The second energy storage component is installed on the first transmission channel to reduce the vibration amplitude caused by the rotation of the descaling unit. Through the installation of the second blade, during the stage when the motor drives the first blade to rotate, the generated gaseous fluid will drive the second blade to rotate, driving the operation of the descaling unit. Through the rotation of the second blade, the brush block removes the dirt on the ring cover. Through the brush arm installed on the second connecting frame, it is convenient to brush away the dirt in the guide cone.

[0019] 3. During operation, the gaseous fluid is guided upward through the channel into the transmission chamber, then moves into the second transmission channel and is guided into the second mounting cover. The screening screen in the second transmission channel prevents impurities and particles from entering the transformer and damaging its durability. The third transmission channel contains multiple channels. According to the laws of fluid dynamics, when the cross-sectional area of ​​the channel decreases, the fluid movement speed will increase, accelerating the fluid transmission efficiency and enhancing the heat exchange efficiency.

[0020] 4. During operation, after the gaseous fluid is guided into the enclosure, some of the fluid flows through the gaps between the ring blocks and the flanges, lengthening the fluid's travel distance, promoting sound rebound and superposition, and enhancing the noise reduction function. Other fluid is guided into the resonant cavity of the cylinder. The resonant cavity has a multi-compartment layout, including multiple rebound planes, which enhances the sound rebound and superposition effect, thus reducing noise. The continuous arrangement of multiple compartments in the resonant cavity enhances the ability to suppress the noise generated by the fluid movement and the operation of the printing press transformer, optimizing the quality of the printing press transformer's operating area. Multiple ventilation units are installed on the porous partition, and the ventilation units are hinged with opening and closing windows via micro-hinges. The storage blocks facilitate the storage and handling of the printing press transformer. When the fluid flows into the enclosure, it pushes the opening and closing windows of the ventilation units on the porous partition to open, promoting the dissipation of heat generated by the fluid and transformer operation. When the fluid flow is interrupted, the opening and closing windows of the porous partition close, effectively preventing external pollutants and moisture from entering the protective enclosure, which is conducive to the smooth operation of the printing press transformer.

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-9 This invention provides a protective cover for a transformer used in a printing press, comprising a transformer 100, a protective cover 200 provided outside the transformer 100, and a linkage module 300 and a transmission module 400 mounted on the protective cover 200.

[0035] The linkage module 300 includes a mounting cover 302, one side of which extends out of the protective cover 200. A mounting frame 303 is fixedly connected to the mounting cover 302 near the protective cover 200. A motor 304 is fixedly connected to the mounting frame 303 away from the protective cover 200. A blade 305 is fixedly connected to the motor 304 away from the mounting frame 303. A guide block 306 is fixedly connected to the center of the mounting cover 302. An elastic pad 307 is fixedly connected to the guide block 306. A [missing information - likely a device or component] is fixedly connected to the side of the mounting cover 302 away from the protective cover 200. The descaling module 308 and guide block 306 are inclined to cause the gaseous fluid to move along the outer wall of the elastic pad 307. The elastic pad 307 captures impurity particles in the fluid, reducing the probability of impurity particles being introduced into the printing press transformer in the protective cover 200. This prevents particles from touching the transformer and causing device malfunction or failure. Then, the gaseous fluid drives the descaling module 308 to rotate, so as to remove impurities and foreign objects on the protective cover, preventing a large accumulation of impurities and foreign objects, which would hinder fluid flow and dissipate the heat generated and accumulated during the operation of the printing press transformer.

[0036] The descaling module 308 includes a housing 309. A flow guide cone 310 is fixedly connected to the inner wall of the housing 309. A second mounting frame 311 is fixedly connected to the middle of the flow guide cone 310. A mounting block 312 is screwed onto the inner wall of the second mounting frame 311. A first transmission channel 313 is fixedly connected to the part of the mounting block 312 opposite to the second mounting frame 311. Energy storage components 314 are fixedly connected to both sides of the first transmission channel 313. A locking block 315 is fixedly connected to the part of the first transmission channel 313 opposite to the mounting block 312. A descaling unit 316 is assembled on the inner wall of the locking block 315. The guide cone 310 facilitates the convergence of gaseous fluids. The first transmission channel 313 is horseshoe-shaped and curved. During the operation of the transformer, heat is generated and accumulated. After the transformer stops operating, the surrounding heat gradually dissipates. In addition, the external temperature fluctuations are alleviated by the installation of the horseshoe-shaped transmission channel 313, which helps to reduce the pipeline tension caused by the temperature difference and regulate the internal pressure fluctuations caused by the temperature difference. This enhances the stability of the descaling module 308 during operation. The second energy storage device 314 is installed on the first transmission channel 313, which helps to reduce the vibration amplitude caused by the rotation of the descaling unit 316.

[0037] The descaling unit 316 includes a linkage block 317, which is inserted and connected to the inner wall of the locking block 315. One side of the linkage block 317 is fixedly connected to a second blade 318. During the stage when the motor 304 drives the first blade 305 to rotate via the installation of the second blade 318, the generated gaseous fluid will drive the second blade 318 to rotate, thereby driving the operation of the descaling unit 316.

[0038] A connecting block 319 is fixedly connected to the part of the linkage block 317 away from the second blade 318. A brush block 320 is fixedly connected to the outside of the connecting block 319. A connecting frame 321 is fixedly connected to the brush block 320. A brush arm 301 is fixedly connected to the part of the connecting frame 321 away from the brush block 320. By rotating the second blade 318, the brush block 320 removes the dirt on the ring cover 309. The brush arm 301 mounted on the connecting frame 321 facilitates the removal of dirt inside the guide cone block 310.

[0039] The transmission module 400 includes a second mounting cover 402, one side of which is fixedly connected to one side of a first mounting cover 302. A second transmission channel 406 is connected to the second mounting cover 402, and a transmission cavity 404 is connected to the other side of the second transmission channel 406. A channel 403 is connected to the transmission cavity 404. A screening screen is installed inside the second transmission channel 406. Gaseous fluid is guided upward through the channel 403 to the transmission cavity 404, and then moves into the second transmission channel 406 and into the second mounting cover 402. The screening screen in the second transmission channel 406 prevents impurities and particles from entering the transformer and damaging its durability.

[0040] A transmission channel 407 is fixedly connected to the part of the mounting cover 2 402 opposite to the mounting cover 1 302. An adjustment unit 408 is installed on the part of the transmission channel 3 407 opposite to the mounting cover 2 402. The transmission channel 3 407 contains multiple channels. According to the laws of fluid dynamics, when the cross-sectional area of ​​the channel decreases, the fluid movement speed will increase, thereby accelerating the fluid transmission efficiency and enhancing the heat exchange efficiency.

[0041] The adjustment unit 408 includes a cover 409, which is mounted on the outer wall of the transmission channel 407. A ring block 410 is fixedly connected to the inner wall of the cover 409. A cylinder 411 is provided on the inner wall of the cover 409 near the ring block 410. A flange 401 is fixedly connected to the side wall of the cylinder 411. A resonant cavity 412 is reserved inside the cylinder 411. Gaseous fluid is guided into the cover 409, and some fluid flows through the gap reserved between the ring block 410 and the flange 401. The passage lengthens the fluid's movement distance, promotes sound rebound and superposition, and enhances the silencing function. Some fluid is guided into the resonant cavity 412 of the cylinder 411. The resonant cavity 412 has a multi-compartment layout and contains multiple rebound planes, which enhances the sound rebound and superposition effect and helps to weaken the sound. Through the continuous arrangement of multiple compartments of the resonant cavity 412, the ability to suppress the sound emitted by the fluid movement and the operation of the printing press transformer is enhanced, and the quality of the printing press transformer's operating area is optimized.

[0042] The protective cover 200 includes a housing 202, on which a holding block 203 is slidably attached. A gripping block 204 is fixedly connected to the part of the holding block 203 away from the housing 202. A porous partition 205 is fixedly connected to one side of the housing 202 adjacent to the holding block 203. A protective module 206 is fixedly connected to the inner wall of the housing 202. Multiple ventilation units are installed on the porous partition 205. The ventilation units are hinged with opening and closing windows via miniature hinges. The holding block 203 facilitates the holding and storage of the transformer for the printing press. When fluid flows into the housing 202, it will push the opening and closing windows of the ventilation units on the porous partition 205 to open, promoting the dissipation of heat generated by the fluid and transformer operation. When the fluid flow is interrupted, the opening and closing windows of the porous partition 205 close, effectively preventing external pollutants and moisture from entering the protective cover, which is conducive to the smooth operation of the printing press transformer.

[0043] The protective module 206 includes a rectangular base block 207 with pre-reserved slots 208. A connecting frame 209 is fixedly connected to the wall of the rectangular base block 207 away from the slots 208. An energy storage component 201 is fixedly connected to the wall of the connecting frame 209 adjacent to the rectangular base block 207. The rectangular base block 207 has multiple pre-reserved slots 208, which makes the rectangular base block 207 easy to deform, which helps to disperse and consume the external force. Together with the energy storage component 201, it is beneficial to the maintenance of the protective cover and the transformer inside.

[0044] The specific implementation method is as follows: The holding block 203 facilitates the holding and storage of the transformer for the printing press. When the fluid flows into the enclosure 202, it pushes the porous partition 205 to open, promoting the dissipation of heat generated by the fluid and transformer operation. When the fluid flow is interrupted, the porous partition 205 closes, effectively preventing external pollutants and moisture from entering the protective cover, which is conducive to the smooth operation of the printing press transformer. The guide block 306 is inclined, causing the gaseous fluid to move along the outer wall of the elastic pad 307. The elastic pad 307 captures impurity particles adhering to the fluid, reducing the probability of impurity particles being introduced into the printing press transformer in the protective cover 200, preventing particles from touching the transformer and causing device malfunction or failure. Subsequently, the gaseous fluid drives the removal of impurity particles. The descaling module 308 rotates to remove impurities and foreign objects from the protective cover, preventing their accumulation and hindering fluid flow. This removes heat generated and accumulated during the operation of the printing press transformer. The guide cone 310 facilitates the convergence of gaseous fluid. The first transmission channel 313 is horseshoe-shaped. Heat is generated and accumulated during transformer operation; as the surrounding heat dissipates after operation, and considering external temperature fluctuations, the horseshoe-shaped transmission channel 313 helps alleviate pipe tension caused by temperature differences and regulates internal pressure fluctuations, enhancing the stability of the descaling module 308 during operation. An energy storage element 314 is installed on the first transmission channel 313 to reduce vibration amplitude caused by the rotation of the descaling unit 316. During the rotation of blade 305 driven by motor 304 via blade 2 318, the generated gaseous fluid drives blade 2 318 to rotate, thus driving the operation of descaling unit 316. The rotation of blade 2 318 causes brush block 320 to remove dirt from the ring cover 309. The brush arm 301 mounted on connecting frame 2 321 facilitates the removal of dirt from the guide cone 310. The gaseous fluid is guided upwards through channel 403 to the transmission chamber 404, then moves into transmission channel 2 406 and into mounting cover 2 402. The screening screen in transmission channel 2 406 prevents impurities from entering the transformer and damaging its durability. Transmission channel 3 407 includes multiple channels, arranged according to… According to the laws of fluid dynamics, when the cross-sectional area of ​​the channel decreases, the fluid movement speed will increase, accelerating the fluid transmission efficiency and enhancing the heat exchange efficiency. The gaseous fluid is guided into the cover 409. Some of the fluid flows through the gap reserved between the ring block 410 and the flange 401, lengthening the fluid movement distance, promoting sound rebound and superposition, and enhancing the noise reduction function. Other fluid is guided into the resonant cavity 412 of the cylinder 411. The resonant cavity 412 has a multi-compartment layout, containing multiple rebound planes, which enhances the sound rebound and superposition effect, which helps to reduce the sound. Through the continuous arrangement of multiple compartments of the resonant cavity 412, the ability to suppress the sound generated by the fluid movement and the operation of the printing press transformer is enhanced, and the quality of the printing press transformer operating area is optimized.
