Description

Technical Field

[0001] This invention relates to the field of power grid supply facilities technology, and in particular to an intelligent power supply cabinet with a chain-type window opener. Background Technology

[0002] Power supply cabinets, serving as control or relay terminals in regional electrical systems, are now widely used in electrical systems such as property management, power transmission and transformation stations, factories, and municipal systems. They are primarily used for power management and protection, providing various power outputs and protection measures to ensure the safe and reliable operation of the system. Functions include power filtering, power conversion, and power restoration. They can provide stable power output to equipment according to system needs and manage and protect the power system. The output voltage and current of the power supply cabinet are relatively stable, mainly meeting the power requirements of production and transmission equipment. The power supply cabinet contains numerous electrical components that generate considerable heat. To dissipate this heat quickly, ventilation windows are typically installed on the outside of the power supply cabinet.

[0003] Existing power supply cabinets have many technical defects in use. First, the chain-type window openers with heat dissipation windows take up a large volume, which is not suitable for narrow cabinet spaces, and installation and disassembly are time-consuming and laborious. Second, the dust screen inside the cabinet easily accumulates dust, reducing the heat dissipation performance of the cabinet. Third, the high humidity inside the cabinet will cause water film to form on the surface of the insulation material of electrical components, resulting in increased leakage current and reduced insulation resistance. In severe cases, it may cause partial discharge or flashover, and also accelerate the corrosion of metal parts inside the cabinet.

[0004] In summary, considering that existing facilities cannot meet the needs of work, we propose an intelligent power supply cabinet with a chain-type window opener. Summary of the Invention

[0015] As a preferred embodiment of the intelligent power supply cabinet with chain-type window opener described in this invention, the dustproof net is installed on the inner side of the heat dissipation vent and is partially connected to the busbar compartment, circuit breaker compartment, cable terminal compartment and relay instrument compartment. A roller is rotatably installed on the upper side of the dustproof net away from the cleaning cotton ball cloth. Both ends of the roller are connected to rollers. Both sets of rollers are connected to the inner wall of the cabinet through positioning bearing seats. A drive motor is installed on one set of positioning bearing seats.

[0016] As a preferred embodiment of the intelligent power supply cabinet with chain window opener described in this invention, the following features are provided: a moisture-proof roll is wound on the roller, the moisture-proof roll covers the dustproof net, several groups of dry particle units are evenly distributed on the moisture-proof roll, dry particles are placed inside the dry particle units, and a breathable membrane is provided on the outer side of each group of dry particle units. The number of breathable membranes is preferably 3-5 groups, and an intercepting angle plate fixed on a positioning bearing seat is provided on the oblique lower side of the roller.

[0017] As a preferred embodiment of the intelligent power supply cabinet with chain window opener described in this invention, the limiting guide plate has an installation groove near the sprocket, a circular lubrication seat is riveted in the installation groove, a rotating rod is rotatably arranged inside the circular lubrication seat, the lower end of the rotating rod is connected to the bottom of the chain box through a fourth bearing seat, a first pulley is sleeved on the rotating rod, a second pulley is sleeved on the positioning shaft, and the first pulley and the corresponding second pulley are connected by a belt for transmission.

[0018] As a preferred embodiment of the intelligent power supply cabinet with chain-type window opener described in this invention, the circular lubrication seat has a motion chamber inside. A polygonal rotating platform is fixed at the upper end of the rotating rod extending into the motion chamber. A polygonal transmission groove is formed upward inside the polygonal rotating platform. A support column is fixed downward inside the motion chamber from the top of the circular lubrication seat. A directional cam extending into the polygonal transmission groove is connected to the lower end of the support column. A cam portion corresponding to the exit direction is provided on the wheel surface of the directional cam. The exit is opened on the outer side of the circular lubrication seat corresponding to the direction of the sprocket. Several sets of guide holes are evenly distributed on the outer circumference of the polygonal rotating platform. An applicator is installed in each set of guide holes. The number of applicators is preferably 10-20 sets.

[0019] As a preferred embodiment of the intelligent power supply cabinet with chain-type window opener described in this invention, the applicator includes a moving rod, a wheel seat, a guide wheel, a return spring, a bristle chuck, and grease bristles. The moving rod is inserted through the guide hole. The wheel seat is fixed at one end of the moving rod located in the polygonal transmission groove. A guide wheel is rotatably installed inside the wheel seat. A portion of the guide wheel extends out of the wheel seat and abuts against the wheel surface of the directional cam. A return spring is fixed between the wheel seat and the inner wall of the polygonal transmission groove and sleeved on the outside of the moving rod. A bristle chuck is installed at the end of the moving rod away from the wheel seat. Several sets of grease bristles are distributed on the bristle chuck. The bristle chuck moves to the outlet and contacts the sprocket using the several sets of grease bristles.

[0020] As a preferred embodiment of the intelligent power supply cabinet with chain window opener described in this invention, a grease box is installed on the inner wall of the motion chamber, and a grease block for grease brush bristles to pick up is provided in the grease box.

[0021] This invention provides an intelligent power supply cabinet with a chain-type window opener, which has the following significant improvements and advantages compared with the prior art: The design incorporates a three-fold chain track. Compared to a single-fold chain track, the coiled folding allows for increased capacity for irregularly shaped chains within a limited space, thereby reducing the size of the chain box and facilitating installation. The design also features a detachable drive assembly, which allows for flexible replacement of gearboxes with different speed ratios by inserting a hexagonal output shaft into a hexagonal socket to meet various needs.

[0022] The return motion of the heat dissipation window causes the pressure bulge protrusion to simultaneously enter the airbag expansion groove, contact and squeeze the smooth pressure plate, causing the corrugated airbag to be compressed. The internal air flows into the sealed airbag and contacts the periphery of the heat dissipation window, achieving a sealing and dustproof function, solving the sealing and dustproof problem of the cabinet, and extending the service life of the power supply cabinet.

[0023] The upper part of the cleaning roller enters the water tank. Clean water enters the water inlet channel through several sets of seepage holes and then flows into the connected water storage chamber. The clean water in the water storage chamber undergoes centrifugal motion as the cleaning roller rotates, and evenly penetrates into several sets of water absorption parts in the gap, moistening the outer cleaning cotton ball cloth. On the one hand, this can absorb dust and improve the wiping effect; on the other hand, it can prevent the formation of a large amount of dust by wetting the dustproof net. At the same time, the cleaning roller enters the water tank. By rotating the cleaning roller at high speed, it generates a relative force with the clean water in the water tank, washing away the dust on the cleaning cotton ball cloth, restoring its dust removal performance, achieving the purpose of automatic cleaning, and significantly improving the dust removal effect.

[0024] Start the drive motor to rotate the roller and release the moisture-proof membrane downwards. On the one hand, it can absorb the humid air inside the cabinet, keep the cabinet dry, and prevent short circuits of electrical components and corrosion of metal parts. On the other hand, the moisture-proof membrane covers the inner side of the dustproof net, blocking some of the humid air from moving into the room during cleaning, thus playing a timely interception role and effectively protecting the power supply cabinet.

[0025] Using the synchronous power of the sprocket's movement, the polygonal rotating table inside the circular lubrication seat rotates, driving several sets of applicators to perform circular motion within the motion chamber. When the brush chuck on the applicator enters the grease box, the grease bristles pick up some of the grease from the grease block. The guide wheel on the applicator rolls from the circumference of the directional cam to the cam position. The interaction between the two generates a squeezing force, causing the wheel seat and the moving rod to move linearly. The moving rod drives the brush chuck to move to the outlet, where several sets of grease bristles contact the sprocket, applying some of the grease from the bristles to the rotating sprocket, maintaining the normal operation of the window opener and achieving automatic lubrication, saving time and effort.

Detailed Implementation

[0028] 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. Example 1

[0029] like Figures 1-14 As shown, this embodiment provides an intelligent power supply cabinet with a chain-type window opener, including a cabinet body 1. The upper end of the cabinet body 1 is provided with a protective roof 3, which has the functions of rain protection and sun shading. The interior of the cabinet body 1 is distributed with a busbar compartment, a circuit breaker compartment, a cable terminal compartment and a relay instrument compartment. An intelligent panel 2 is provided at the upper position of the front face of the cabinet body 1. The intelligent panel 2 has the functions of display and control. A heat dissipation vent 4 is provided at the middle position of the side of the cabinet body 1. A heat dissipation window 5 is movably arranged in the heat dissipation vent 4. The specific shape and size of the heat dissipation window 5 are designed according to the actual situation. The heat dissipation window 5 is connected to the inner wall of the heat dissipation vent 4 by a rotating component 6.

[0030] The bottom of the heat dissipation vent 4 is provided with a side inner liner 10, the upper end of the side inner liner 10 is equipped with a chain box 11, and the upper end of the chain box 11 is equipped with a detachable drive assembly 12, such as... Figures 2-4 As shown.

[0031] In this embodiment, a limiting guide plate 13 is horizontally arranged inside the chain box 11. Symmetrically installed inside the limiting guide plate 13 are three-fold chain rails 14 for the movement of the irregularly shaped chains 15. The three-fold chain rails 14 serve both storage and guiding functions. A chain guide opening 16 is provided in the center of the chain box 11 facing the heat dissipation window 5. The two sets of irregularly shaped chains 15 interlock at the chain guide opening 16. Figure 5 and Figure 6 As shown.

[0032] In this embodiment, a chain buckle 17 is installed at the bottom of the heat dissipation window 5. The outer ends of two sets of irregularly shaped chains 15 are connected to the chain buckle 17, and the lower end of the chain buckle 17 is connected to a pressure bladder protrusion 18, such as... Figure 3 and Figure 4 As shown.

[0033] Furthermore, the chain box 11 is symmetrically equipped with sprockets 20 that mesh with the irregularly shaped chain 15. Two sets of sprockets 20 are respectively sleeved on positioning shafts 21. The lower ends of the two positioning shafts 21 are connected to the bottom of the chain box 11 via a first bearing seat 22. Figure 5 and Figure 6 As shown.

[0034] Specifically, two sets of positioning shafts 21, located above the sprockets 20, are fitted with meshing reversing gears 23. The two sets of reversing gears 23 are of the same size. One set of positioning shafts 21 has an upward-facing hexagonal insertion hole 24 inside, for inserting a hexagonal output shaft from the detachable drive assembly 12. Figure 5 and Figure 6 As shown.

[0035] Furthermore, an airbag telescopic groove 30 is provided on the outer side of the upper end face of the side inner liner 10. A corrugated airbag 31 is movably disposed within the airbag telescopic groove 30. The corrugated airbag 31 has deformation and recovery performance, enabling effective telescopic movement. One end of the corrugated airbag 31 is provided with a smooth pressure plate 32 that interacts with the pressure bag protrusion 18. The smooth pressure plate 32 and the pressure bag protrusion 18 have relative sliding to ensure that the corrugated airbag 31 can bear horizontal force. The end of the corrugated airbag 31 away from the smooth pressure plate 32 is connected to the inner wall of the airbag telescopic groove 30 via an airbag fixing sleeve 33. Figure 2 and Figure 7 As shown.

[0036] The heat dissipation vent 4 is provided with a sealing airbag positioning groove 38 around its perimeter. Two sets of first sealing airbags 35 and one set of second sealing airbags 37 are installed within the sealing airbag positioning groove 38. After air is introduced, the first and second sealing airbags 35 and 37 partially extend out of the sealing airbag positioning groove 38 and contact the periphery of the heat dissipation window 5. The upper ends of the two sets of first sealing airbags 35 are connected to the two ends of the second sealing airbag 37 via a first ventilation pipe 36, respectively. The lower ends of the two sets of first sealing airbags 35 are connected to the airbag fixing sleeve 33 via a second ventilation pipe 34, respectively. The second ventilation pipe 34 passes through the airbag fixing sleeve 33 and connects to the corrugated airbag 31. Figure 2 and Figure 7 As shown.

[0037] When the pressure bulge 18 moves away from the corrugated airbag 31, the corrugated airbag 31 automatically expands outward through its own deformation and recovery property, drawing in some of the gas from the first sealing airbag 35 and a set of second sealing airbags 37, and causing both to contract.

[0038] Furthermore, a water trough 40 is provided inside the side inner liner 10. A water inlet pipe 41 extends symmetrically upwards through the side inner liner 10 into the water trough 40. The upper end of the water inlet pipe 41 is connected to a rainwater collection box 42 located on the protective roof 3. A filter membrane 43 is installed inside the rainwater collection box 42. The filter membrane 43 intercepts impurities. When the power supply cabinet is located indoors, water can be manually added to the water trough 40. Figure 1 and Figure 10 As shown.

[0039] The bottom of the sink 40 extends outward from the cabinet 1 via a drain pipe 44, which contains a drain valve. Symmetrical overflow pipes 45 extend outward from the upper middle part of the sink 40, automatically overflowing to prevent excessive water level in the sink 40. Figures 8-10 As shown.

[0040] In this design, a first opening groove 46 is centrally located on the upper surface of the side inner liner 10, away from the airbag telescopic groove 30. Two second opening grooves 47 are symmetrically connected to both ends of the first opening groove 46. A third opening groove 48 is connected to one end of each set of second opening grooves 47. Figures 8-10 As shown.

[0041] Furthermore, vertical limiting grooves 50 are symmetrically provided on the two inner sides of the heat dissipation vent 4. A vertical lead screw 51 is rotatably installed within each set of vertical limiting grooves 50. The vertical lead screw 51 extends downwards into the bottom of the water tank 40. Second bearing seats 52 are sleeved at both the upper and lower ends of the vertical lead screw 51. One set of vertical lead screws 51 extends upwards and is connected to a lead screw motor 53 via a coupling. Figure 2 , Figure 8 , Figure 9 and 11 As shown.

[0042] In this configuration, the upper ends of both sets of vertical lead screws 51 are fitted with synchronous sprockets 54, and the two sets of synchronous sprockets 54 are connected and driven by synchronous chains 55. Figure 11 As shown.

[0043] Furthermore, each of the two sets of vertical lead screws 51 is movably equipped with a displacement seat 60, which is compatible with the third opening slot 48. A lead screw nut sleeve 61 (containing a helically moving lead screw nut) is installed inside the displacement seat 60, acting on the vertical lead screw 51. Figure 11 As shown.

[0044] In this embodiment, a cleaning roller 63 is rotatably arranged between the two sets of displacement seats 60. The cleaning roller 63 is adapted to the first opening groove 46. Short shafts 64 are welded to both ends of the cleaning roller 63. The short shafts 64 are adapted to the second opening groove 47. The short shafts 64 are connected to the inner surface of the displacement seat 60 by a third bearing seat 65. Figure 11 and Figure 12 As shown.

[0045] In this embodiment, a set of short shafts 64 extends into the displacement seat 60 and is fitted with a large gear 66. A small gear 67 is meshed on the upper end face of the large gear 66. The small gear 67 is fitted onto the output shaft of the servo motor 68. The servo motor 68 is installed inside the motor housing 62, which is riveted to the upper end of one set of displacement seats 60. Figure 12 As shown.

[0046] Furthermore, the outer side of the cleaning roller 63 is wrapped with a cleaning cotton ball cloth 70 that contacts the outer surface of the dustproof net 7. The surface of the cleaning cotton ball cloth 70 is provided with several sets of flexible protrusions, which have the property of deformation and extension, and also reduce the squeezing force on the dustproof net 7. The cleaning roller 63 has a water storage cavity 71 inside, and several sets of slits 72 are formed on the cavity wall of the water storage cavity 71. Several sets of water-absorbing parts 73 on the cleaning cotton ball cloth 70 are fixed in the slits 72, such as... Figure 12 and Figure 13 As shown.

[0047] The short shaft 64 has an internal water inlet channel 74 connected to the water storage chamber 71. The water inlet channel 74 can be designed as an oblique guide type. Several sets of seepage holes 75 connected to the water inlet channel 74 are evenly distributed on the outer surface of the short shaft 64. Figure 13 As shown.

[0048] Furthermore, the dustproof net 7 is installed on the inner side of the heat dissipation vent 4, and is partially connected to the busbar compartment, circuit breaker compartment, cable terminal compartment, and relay instrument compartment, serving as an isolation and dustproof function. A roller 80 is rotatably mounted on the upper side of the dustproof net 7 away from the cleaning cotton ball cloth 70. Both ends of the roller 80 are connected to rollers 81. Both sets of rollers 81 are connected to the inner wall of the cabinet 1 through positioning bearing seats 82. A drive motor 83 is installed on one set of positioning bearing seats 82. Figure 9 and Figure 14 As shown.

[0049] The moisture-proof roll 84 is wound on the roller 80, covering the dustproof net 7. Several groups of dry particle units 85 are evenly distributed on the moisture-proof roll 84, with dry particles placed inside each unit. Each group of dry particle units 85 has a breathable membrane 86 on its outer surface. Figure 14 As shown Among them, the lower oblique side of the roller 80 is provided with an intercepting angle plate 87 fixed on the positioning bearing seat 82. The intercepting angle plate 87 has the function of receiving waste material and waste liquid, such as Figure 14 As shown.

[0050] Furthermore, the dimensions and positions of the above structural components are adapted to the actual power supply cabinet structure.

[0051] In this embodiment, when each inner chamber of the cabinet 1 needs heat dissipation, the drive motor of the detachable drive assembly 12 is activated. The hexagonal output shaft drives one of the positioning shafts 21 to rotate. Through the meshing transmission of two sets of reversing gears 23, the sprockets 20 on the two sets of positioning shafts 21 rotate synchronously in opposite directions. This causes the irregularly shaped chains 15 in the two sets of three-fold chain rails 14 to extend outwards synchronously, jointly pushing the heat dissipation window 5 to flip upwards and open, exposing the heat dissipation gap at the heat dissipation vent 4 to release the heat of the inner chamber. During heat dissipation, the dustproof net 7 is used to block dust from the external environment to avoid contaminating the inner chamber.

[0052] As the two sets of irregularly shaped chains 15 slowly retract, they pull the heat dissipation window 5 back to the heat dissipation vent 4. Simultaneously, the pressure bulge 18 at the lower end of the chain buckle 17 enters the airbag telescopic groove 30, contacts and squeezes the smooth pressure plate 32, causing the corrugated airbag 31 to be compressed. The air inside enters the first sealing airbag 35 through the two sets of second ventilation pipes 34, causing the first sealing airbag 35 to inflate and expand, partially extending out of the sealing airbag positioning groove 38 and contacting the two sides of the heat dissipation window 5, achieving a sealing and dustproof function. At the same time, the excess air in the first sealing airbag 35 enters the corresponding second sealing airbag 37 through the first ventilation pipe 36, causing the second sealing airbag 37 to inflate and expand (the entire loop is in a balanced state), partially extending out of the sealing airbag positioning groove 38 and contacting the top area of ​​the heat dissipation window 5, achieving a sealing and dustproof function.

[0053] When it rains, rainwater is directed downwards on the protective roof 3, with some flowing into the rainwater collection box 42. After passing through the filter membrane 43 to filter impurities, the rainwater is injected into the water tank 40 through the water inlet pipe 41 for temporary storage as a reserve of clean water. After prolonged use, dust accumulates on the dustproof net 7, affecting heat dissipation. In this case, the drive motor 83 is first started to rotate the roller 80, releasing the moisture-proof roll 84 downwards to cover the inner side of the dustproof net 7. Then, the lead screw motor 53 is started to drive one of the vertical lead screws 51 to rotate, and the rotation is achieved through two sets of synchronous sprockets. The connection and transmission of 54 and synchronous chain 55 cause the two sets of vertical screws 51 to rotate synchronously and in the same direction, causing the two sets of displacement seats 60 located at the third opening groove 48 to move downward first (at this time, the cleaning roller 63 is in the first opening groove 46, which is sealed and has the function of sealing and preventing moisture). Together, they drive the upper part of the cleaning roller 63 into the water tank 40. At this time, part of the short shaft 64 is also in the water tank 40 and in contact with clean water. At this time, the clean water enters the water inlet channel 74 through several sets of seepage holes 75 and then flows into the connected water storage chamber 71.

[0054] Then, the two sets of displacement seats 60 drive the cleaning roller 63 away from the water tank 40, and the cleaning cotton ball cloth 70 contacts the bottom of the dustproof net 7. The servo motor 68 is immediately started, driving the small gear 67 to rotate, and through meshing, the large gear 66 rotates. The two sets of short shafts 64 drive the cleaning roller 63 to rotate, causing the cleaning cotton ball cloth 70 to roll along the dustproof net 7 (the flexible protrusions on the cleaning cotton ball cloth 70 will randomly enter the mesh). The dust inside and outside the dustproof net 7 is wiped away by the contact force. During the wiping process, the clean water in the water storage chamber 71 undergoes centrifugal motion and evenly penetrates into the several sets of water absorption parts 73 in the gap 72, making the external cleaning cotton ball cloth 70 wet. On the one hand, it can absorb dust and improve the wiping effect. On the other hand, by wetting the dustproof net 7, a large amount of dust is avoided. When some humid air moves into the room, it is intercepted by several sets of dry particle units 85 on the moisture-proof roll 84, and the dry particles absorb the moisture.

[0055] During or after cleaning, the two sets of displacement seats 60 drive the cleaning rollers 63 back into the water tank 40. By making the cleaning rollers 63 rotate at high speed, they generate a relative force with the clean water in the water tank 40, washing away the dust on the cleaning cotton ball cloth 70 and restoring its dust removal performance. The sewage in the water tank 40 is discharged outward by opening the drain valve on the drain pipe 44. Example 2

[0056] Based on Example 1, the two sets of irregularly shaped chains 15 inside the window opener are prone to low-slip wear after prolonged use. Manually adding lubricant to the window opener is time-consuming and laborious. To solve this problem, we have the following design: Figures 15-19 As shown Specifically, a mounting groove 90 is provided on the limiting guide plate 13 near the sprocket 20. A circular lubrication seat 91 is riveted into the mounting groove 90. A rotating rod 92 is rotatably mounted inside the circular lubrication seat 91. The lower end of the rotating rod 92 is connected to the bottom of the chain box 11 through a fourth bearing seat 93. Figures 15-17 As shown.

[0057] In this configuration, a first pulley 94 is sleeved on the rotating rod 92, and a second pulley 95 is sleeved on the positioning shaft 21. The first pulley 94 and the corresponding second pulley 95 are connected by a belt 96 for transmission. Figure 15 As shown.

[0058] Furthermore, a motion chamber 100 is provided inside the circular lubrication seat 91. A polygonal rotary table 101 is fixed to the upper end of the motion chamber 100 by a rotating rod 92. A polygonal transmission groove 102 is formed upward inside the polygonal rotary table 101, such as... Figure 16 and Figure 18 As shown.

[0059] The top of the circular lubrication seat 91 extends downward into the motion chamber 100 and is fixed with a support column 103. The lower end of the support column 103 is connected to a directional cam 104 that extends into the polygonal transmission groove 102. The directional cam 104 has a cam portion 105 on its wheel surface corresponding to the direction of the outlet 106. The size of the cam portion 105 is designed according to the width of the outlet 106. The outlet 106 is located on the outer side of the circular lubrication seat 91 in the direction corresponding to the sprocket 20. Figures 16-18 As shown.

[0060] Among them, the outer peripheral surface of the polygonal rotary table 101 has several sets of guide holes 107 evenly distributed, and each set of guide holes 107 is equipped with an applicator 110, such as Figure 18 As shown.

[0061] Specifically, the applicator 110 includes a moving rod 111, a wheel seat 112, a guide wheel 113, a return spring 114, a bristle chuck 115, and grease bristles 116, such as... Figure 19 As shown.

[0062] In this embodiment, a moving rod 111 is provided through the guide hole 107. A wheel seat 112 is fixed at one end of the moving rod 111 located in the polygonal transmission groove 102. A guide wheel 113 is rotatably provided inside the wheel seat 112. A portion of the guide wheel 113 extends out of the wheel seat 112 and abuts against the wheel surface of the directional cam 104. A return spring 114 is fixed between the wheel seat 112 and the inner wall of the polygonal transmission groove 102 and sleeved on the outside of the moving rod 111. A brush chuck 115 is installed at the end of the moving rod 111 away from the wheel seat 112. Several sets of grease bristles 116 are distributed on the brush chuck 115. When the brush chuck 115 moves to the outlet 106, it contacts the sprocket 20 using the several sets of grease bristles 116.

[0063] Furthermore, a grease box 108 is installed on the inner wall of the exercise room 100, and the grease box 108 contains grease blocks 109 for the grease brush bristles 116 to pick up, such as... Figure 18 As shown.

[0064] It should be noted that the contact between the grease bristles 116 of each applicator 110 and the sprocket 20 is not instantaneous, but will cover a certain range of the circumferential surface of the sprocket 20. Therefore, even if both the sprocket 20 and the applicator 110 are in regular motion, the combined action of several applicators 110 will ensure that the sprocket 20 is fully lubricated.

[0065] In this embodiment, when the two sets of sprockets 20 are in motion, the second pulley 95 on the positioning shaft 21 rotates accordingly, and the rotating rod 92 on the first transmission pulley 94 is connected by the belt 96, causing the polygonal rotating table 101 inside the circular lubrication seat 91 to rotate, thereby driving several sets of applicators 110 to perform circular motion in the motion chamber 100. When the bristle chuck 115 on the applicator 110 enters the grease box 108, the grease bristles 116 pick up part of the grease on the grease block 109, and then the bristle chuck 115 moves towards the outlet 106. At this time, the guide wheel 113 on the applicator 110 rolls from the circumferential surface of the directional cam 104 to the cam. At position 105, the interaction between the two generates a squeezing force, causing the wheel seat 112 and the moving rod 111 to move linearly. The moving rod 111 drives the brush chuck 115 to move to the outlet 106. Several sets of grease brushes 116 come into contact with the sprocket 20, applying some of the grease from the brushes 116 to the rotating sprocket 20. Then, when the guide wheel 113 leaves the cam section 105, the moving rod 111 returns to its original position under the compression force of the return spring 114, causing the brush chuck 115 to return to the motion chamber 100. Several sets of applicators 110 act on the sprocket 20 in sequence, ensuring that the sprocket 20 is fully lubricated, which facilitates the stable operation of the irregular chain 15.
