Description

Technical Field

[0001] The present invention belongs to the field of power-saving devices, and more specifically, relates to a power-saving device with a protection structure. Background Art

[0002] Power-saving devices are widely used in industrial, commercial, and household power systems to optimize the efficiency of electricity use and reduce energy waste. However, during actual operation, the devices are often affected by problems such as mechanical vibration, dust accumulation, and poor heat dissipation, resulting in performance degradation or even failure. Traditional solutions usually adopt independent shock absorption, dust prevention, and heat dissipation designs, which not only have a complex structure but also increase additional energy consumption. Therefore, how to utilize the operating characteristics of the device itself (such as vibration) to achieve self-maintenance functions (such as cleaning and heat dissipation) without relying on external energy while maintaining high power-saving performance has become an important research direction in the current technical field. The traditional shock absorption solutions commonly used in current power-saving devices for vibration protection have obvious energy efficiency defects. Specifically, such devices usually configure passive shock absorption elements such as rubber shock pads and metal buffer springs. Although they can absorb and isolate mechanical vibration to a certain extent, this design completely dissipates the precious vibration mechanical energy in the form of heat, failing to achieve the recycling of energy and causing significant energy waste. At the same time, in order to maintain the normal operating temperature of the device and keep the interior clean, many power-saving devices have to additionally configure a cooling fan driven by an electric motor and a mechanical scraper device. Although this external power system solves the problems of heat dissipation and cleaning, it brings new energy consumption contradictions: on the one hand, these auxiliary devices need to continuously consume additional electrical energy to maintain operation; on the other hand, their energy consumption level often forms an antagonistic relationship of mutual growth and decline with the power-saving effect of the device itself, seriously weakening the overall energy-saving performance of the device. More notably, in application scenarios such as field operations or unstable power supply, this protection system relying on external power supply is likely to completely fail due to power outage, resulting in the device facing the risk of overheating or dust accumulation.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0019] It should be noted that these attached drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0020] Now, the present invention will be further described in detail with reference to the attached drawings.

[0021] Please refer to Figures 1-6 As shown, in this embodiment, a power-saving device with a protection structure is provided, including a base 1. A placing plate 2 is arranged above the base 1, and a power-saving device is arranged above the placing plate 2. The power-saving device includes an outer shell 3. An air outlet 4 is opened on one side of the outer shell 3. An air outlet assembly located on one side of the air outlet 4 is arranged above the placing plate 2. A cleaning assembly for scraping the side wall of the air outlet 4 is arranged inside the outer shell 3; A driving mechanism and a shock absorption structure are arranged between the base 1 and the placing plate 2. Among them, the driving mechanism is used to drive the air outlet assembly and the cleaning assembly; A socket 5 is arranged on one side of the outer shell 3, and a shielding assembly for shielding the socket 5 is slidably connected to one side of the outer shell 3.

[0022] By utilizing the downward movement generated by the vibration of the placement plate 2 during the operation of the device, the driving mechanism is excited to drive the air outlet assembly and the cleaning assembly to operate synchronously. This design not only makes full use of the vibration energy of the device itself, improving the energy utilization rate, but also enables the exhaust air at the air outlet 4 and the internal cleaning process to be automatically carried out, reducing manual intervention. At the same time, the addition of the shock-absorbing structure ensures the stable descent of the placement plate 2, avoiding excessive impact from affecting the operation of the device.

[0023] In this embodiment, the shock-absorbing structure includes dampers 6 located at the four corners of the base 1 and the placement plate 2 respectively. A spring 7 sleeved on the periphery of the damper 6 is fixedly connected between the base 1 and the placement plate 2. A positioning cylinder 8 is fixedly connected to each of the four corners of the base 1, and an installation cylinder 9 is connected to each of the four corners below the base 1. A silica gel column 10 is arranged between the positioning cylinder 8 and the installation cylinder 9.

[0024] It should be noted that: by respectively arranging dampers 6 at the four corners of the base 1 and the placement plate 2, the vibration generated during the operation of the device is effectively absorbed and dispersed, reducing the impact on the stability of the device. The addition of the spring 7 enhances the buffering effect, enabling the placement plate 2 to maintain balance when subjected to vibration and avoiding violent shaking. In addition, silica gel columns 10 are arranged between the positioning cylinders 8 and the installation cylinders 9 at the four corners of the base 1, further improving the overall shock-absorbing performance, which can not only reduce the damage of vibration to the internal structure of the device, but also reduce noise and extend the service life of the device.

[0025] In this embodiment, the air outlet assembly includes a connecting cylinder 11. A sliding rod 12 is slidably connected inside the connecting cylinder 11. One end of the sliding rod 12 is fixedly connected with a piston 13 closely attached to the inner wall of the connecting cylinder 11. The air outlet hole of the connecting cylinder 11 communicates with an air outlet pipe 14. Branch pipes 15 are respectively connected to the air outlet pipe 14, and spray nozzles 16 corresponding to a plurality of air outlets 4 are arranged on one side of the branch pipes 15.

[0026] It should be noted that: the sliding rod 12 is connected to an external driving mechanism. When the device operates, the reciprocating movement of the connecting seat 33 drives the sliding rod 12 to push and pull the piston 13, forming a periodic air pressure change inside the connecting cylinder 11. The sealing ring of the piston 13 ensures the unidirectional flow of air. During the compression stroke, the air is forced to be discharged from the air outlet hole, branched to each branch pipe 15 through the air outlet pipe 14, and finally a directional air flow is formed by the spray nozzles 16. This design realizes the direct coupling of mechanical movement and air flow output, and the air outlet action can be completed without an additional power source.

[0027] Furthermore: by spraying the outside of the air outlet 4 with the spray nozzles 16, a uniform spraying coverage layer can be formed on its surface, thereby effectively reducing the accumulation of attachments such as dust and oil stains and improving the cleanliness of the air outlet 4.

[0028] In this embodiment, the cleaning component includes a scraper 17 sliding on the inner wall of the housing 3. On one side of the inner wall of the housing 3, a linear guide rail 18 is fixedly connected. On one side of the linear guide rail 18, a slider is slidably connected. The slider and the scraper 17 are fixedly connected. On one side of the inner wall of the housing 3, a plate body 42 is fixedly connected. A fourth spring 43 is fixedly connected between the plate body 42 and the scraper 17.

[0029] It should be noted that through the setting of the scraper 17, the dust accumulated at the air outlet 4 can be effectively scraped off, preventing the dust from blocking the air outlet 4 and affecting the normal operation of the device. At the same time, during the movement of the scraper 17, it can also clean the inner wall of the housing 3, reduce dust adhesion, and keep the inside clean. In addition, the cooperation between the scraper 17 and the spring 7 enables it to perform reciprocating motion, ensuring a more thorough scraping effect, not only improving the cleaning efficiency but also extending the service life of the device.

[0030] In this embodiment, on one side of the base 1 and the placement plate 2, a first plate body 19 and a second plate body 20 are respectively fixedly connected. On the opposite side of the first plate body 19, a threaded hole is formed. A bolt 21 is threadedly connected inside the threaded hole, and the bottom of the bolt 21 contacts the upper part of the second plate body 20.

[0031] It should be noted that: during the transportation preparation stage, the staff only needs to tighten the bolt 21 to a predetermined torque to eliminate all the moving clearances between the base 1 and the placement plate 2, making the shock-absorbing component temporarily in a fixed state, effectively preventing relative displacement or collision damage caused by vibration during transportation.

[0032] In this embodiment, the driving mechanism includes a rod body 22. At both ends of the rod body 22, gears 23 are fixedly connected. Above the upper edge of the base 1, a rack 24 meshing with the gears 23 is fixedly connected. Above the base 1, a plurality of linear slide rails 25 are fixedly connected. Above the linear slide rails 25, a guide block is slidably connected. Above the guide block, a bearing seat 26 is fixedly connected. The rod body 22 is rotatably connected inside the bearing seat 26. Among them, on one side of the linear slide rail 25, a connecting plate 27 is fixedly connected. A spring 7 is arranged between the connecting plate 27 and the bearing seat 26.

[0033] It should be noted that: through the meshing transmission between the gears 23 and the rack 24, the precise rotation of the rod body 22 can be efficiently achieved, ensuring the stability and reliability of power transmission. At the same time, the cooperation between the linear slide rails 25 and the guide block enables the rod body 22 to maintain a fixed trajectory during movement, reducing position deviation caused by lateral force or vibration. In addition, the addition of the spring 7 provides an additional buffering effect when the placement plate 2 descends, further absorbing and dispersing the impact force generated by vibration and enhancing the shock-absorbing effect.

[0034] In this embodiment, a winding drum 28 is fixedly connected to the edges of both ends of the rod body 22, an extension portion 29 is fixedly connected to one side of the scraper 17, a connecting block 30 is slidably connected below the extension portion 29, a winding rope 31 is provided between the circumferential side of the winding drum 28 and the connecting block 30, and a sliding groove for the winding rope 31 to move is opened between the placement plate 2 and the bottom of the shell 3.

[0035] It should be noted that: the winding drum 28 is linked with the driving mechanism, and the winding rope 31 is wound in an orderly manner through the rotational movement during the operation of the equipment, thereby generating a stable traction force. This traction force is transmitted to the scraper 17 through the pulley block, so that it performs precise vertical reciprocating motion along the guide rail on the inner wall of the shell 3. The scraper 17 is made of a flexible and wear-resistant material, and its edge is appropriately fitted with the inner wall of the shell 3, and can effectively peel off dust and dirt attached to the inner wall during the up and down movement.

[0036] In this embodiment, a wedge plate 32 is fixedly connected to the lower part of the placement plate 2, a connecting seat 33 is rotatably connected to the middle part of the rod body 22, one side of the connecting seat 33 is fixedly connected to a positioning rod 34 fixedly connected between the sliding rod 12, and the slope of the wedge plate 32 is tightly fitted to the peripheral side of the outer wall of the connecting seat 33.

[0037] It should be noted that: by providing the wedge plate 32, when the power-saving device vibrates during use, the placement plate 2 will move toward the base 1 along the slope of the wedge plate 32. Since the wedge plate 32 fits tightly against the connecting seat 33, its downward movement will push the connecting seat 33 to shift, causing the rod body 22 connected thereto to rotate around the axis, thereby driving the winding drum 28 to reel in or release. In addition, during the translation of the placement plate 2, the movement of the connecting seat 33 can not only drive the rod body 22 to rotate, but also further push the slide rod 12 to slide along the linear track through the linkage structure, thereby realizing the synchronous adjustment of the cleaning component or the air outlet component. This design uses the vibration energy of the equipment itself to drive multiple mechanisms to move in coordination, thereby improving the mechanical efficiency of the overall system, and realizing automatic adjustment without the need for an additional power source, thereby enhancing the energy-saving effect and stability of the equipment.

[0038] In this embodiment, the shielding assembly includes guide frames 35 fixedly connected to the outer walls of both sides of the socket 5, and a shielding plate 36 for shielding the socket is slidably connected between the two guide frames 35.

[0039] It should be noted that: by setting the baffle 36, each position of the jack can be effectively covered, preventing dust and foreign objects from entering or accidental contact, and improving the safety and service life of the jack. At the same time, the setting of the guide frame 35 ensures that the baffle 36 is always in a controlled state during the movement process, avoiding jamming or poor operation caused by suspension or inclination. The guide frame 35 not only provides a stable sliding track, but also enhances the force balance of the baffle 36, making it smoother during the opening and closing process, reducing resistance and wear.

[0040] In this embodiment, a guide rod 37 is slidably connected to one side of the housing 3, a combined rod 38 is fixedly connected to the lower part of the baffle 36, a threaded disk 39 is rotatably connected to one side of the housing 3, the guide rod 37 and the combined rod 38 are both threadedly connected to the threaded disk 39, a clamping rod 40 is fixedly connected to one end of the guide rod 37, and clamping grooves adapted to the clamping rod 40 are formed on both sides of the placing plate 2.

[0041] It should be noted that: the surface of the threaded disk 39 is provided with first planar threads, and the sides of the guide rod 37 and the positioning rod 34 are both provided with second planar threads that cooperate with the first planar threads. The cooperation of the first planar threads and the second planar threads realizes the fixation of the positions of the guide rod 37 and the combined rod 38, avoiding the occurrence of random sliding.

[0042] Furthermore, during the operation of the device, when it is necessary to insert a plug, the threaded disk 39 is manually rotated and driven. The first planar threads on its surface mesh with the second planar threads on the guide rod 37 and the positioning rod 34, driving the baffle 36 to move smoothly downward along the guide frame 35, so as to completely expose the socket 5 for connection. At the same time, the downward movement of the positioning rod 34 is converted into the horizontal displacement of the guide rod 37 through threaded cooperation, so that the clamping rod 40 at its end accurately fits into the clamping groove on the side of the placing plate 2 to form a mechanical interlock. This linkage design ensures that two key functions are completed synchronously: on the one hand, the occlusion of the socket 5 is released for use, and on the other hand, the entire power-saving device is locked to the base 1 through the rigid cooperation of the clamping rod 40 and the clamping groove, effectively suppressing the vibration displacement during transportation. It is particularly worth noting that when the device is powered off and ready for transportation, rotating the threaded disk 39 in the reverse direction will first cause the clamping rod 40 to disengage from the clamping groove to release the lock, and then drive the baffle 36 to move upward to completely close the socket 5. This sequential action mechanism not only ensures the convenience during use, but also ensures that the socket 5 is always under the sealing protection of the baffle 36 during transportation, completely avoiding dust and foreign objects from invading the device interior through the socket 5, and significantly improving the environmental adaptability and transportation safety of the product.

[0043] Furthermore, a dovetail block is fixedly connected to one side of the guide rod 37, and a dovetail groove for the dovetail block to slide is formed on one side of the housing 3.
