Description

Technical Field

[0001] The present invention relates to the technical field related to tunnel ventilation, and in particular to environmental ventilation equipment for extra-long kilometer tunnels. Background Art

[0002] In tunnels, especially long tunnels, dirty gases are prone to accumulate, such as automobile exhaust in highway tunnels and methane in mine tunnels. To ensure safety, ventilation and other methods are usually used to create the required air environment for tunnels and underground construction projects. Different tunnels and underground projects have their own ventilation requirements. Due to different geographical and climatic conditions, building structures and internal production processes, the ventilation technical measures adopted should also be different.

[0003] In the existing tunnel ventilation process, such as the Chinese patent with announcement number CN117703480A, a tunnel intelligent ventilation system is disclosed, including a tunnel wall and a ventilation component, the ventilation component includes multiple ventilation ducts, multiple lifting cylinders, multiple lifting rods, a fixed frame, a separation frame, multiple fixed units, multiple fans and an intelligent unit. The tunnel wall has a first groove, and multiple ventilation ducts are all connected to the first groove. Multiple lifting cylinders are fixedly connected to the tunnel wall and are distributed in sequence on the inner top wall of the first groove. The output ends of the multiple lifting cylinders are respectively fixedly connected to the corresponding lifting rods, one end of the lifting rods is fixedly connected to the fixed frame and symmetrically distributed on both sides of the lifting rods. Multiple fixed units are respectively arranged at the other end of the corresponding lifting rods. The separation frame is connected to the lifting rod through multiple fixed units. Multiple fans are fixedly connected to the separation frame and are distributed in sequence above the separation frame. Multiple fans are connected to the bottom of the fixed frame. The fixed frame is located below the multiple ventilation ducts, and the intelligent unit is arranged on the separation frame.

[0004] In the above-mentioned prior art, the air quality and temperature conditions in the tunnel are mainly detected by the intelligent unit to realize intelligent ventilation. However, the above-mentioned prior art does not take into account that for some extra-long tunnels, the dirty gas gathers quickly, and it is extremely difficult for the fresh air from the outside to naturally penetrate deep into the tunnel for ventilation. Therefore, the ventilation work of the extra-long tunnel should be operated for a long time. During the long-term ventilation work, a large amount of dust and impurities in the air will block the ventilation equipment and reduce the ventilation effect, and may even adhere to the ventilation equipment and make it unable to work normally. In addition, due to the large size of the ventilation equipment used in the tunnel, the maintenance of the ventilation equipment is also more difficult, time-consuming and labor-intensive.

[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

[0006] In order to reduce the impact of impurities such as dust in the air on ventilation equipment when ventilating tunnels, to conveniently maintain the ventilation equipment, and to enable the ventilation equipment to operate stably and efficiently for a long time, the present application provides a ventilation device for an extra-long kilometer tunnel environment.

[0007] The present application provides a ventilation device for an extra-long kilometer tunnel environment using the following technical solution:

The metal filter in the prior art performs primary filtration on the air. The metal filter has the advantages of large ventilation volume, large dust holding capacity, low initial resistance, and strong fireproof performance. Coarse dust particles in the air (and other impurities such as paper pieces, broken leaves, etc.) can be intercepted by the metal filter. A spring is connected between the metal filter and the mounting frame. The spring is reset together. The scraper plate is vertically mounted on the air inlet cylinder. On the inner wall, the scraper plate is in contact with the surface of the metal filter. When the metal filter rotates, the scraper plate scrapes the surface of the metal filter, thereby scraping off the impurities intercepted by the metal filter. The scraper plate and the metal filter are coordinated by a vibrating mechanism, and the vibrating mechanism makes the metal filter vibrate, thereby facilitating the falling of impurities intercepted by the metal filter.

When working, the docking piece rotates synchronously with the rotating hub. After the rotating hub stops rotating, the docking piece is squeezed to a specified rotation angle by squeezing the clamping piece and the docking piece. At the same time, the position of the docking piece is locked, and accordingly, the rotating hub is locked at the specified rotation angle, thereby facilitating the cleaning of the fan blades installed on the rotating hub.

[0014] Preferably, the cleaning module includes a connecting base, a rotating bracket, a rotating head, a cleaning roller, a guide rail, a flip gear, a flip rack, a rotating gear, a rotating rack, and a self-cleaning mechanism. The connecting base is installed on the mobile frame, and the rotating bracket is slidably arranged on the connecting base. A spring five is connected between the rotating bracket and the connecting base. The spring five plays a role in resetting and maintaining the stability of the rotating bracket to prevent the rotating bracket and the connecting base from sliding randomly.

A brush layer is arranged on the surface of the cleaning roller. The brush layer plays a cleaning role. The guide rail is installed on the inner wall of the mounting seat. The guide rail corresponds to the position angle of the fan blade. The clamping piece and the docking piece are squeezed together. After that, the rotating wheel hub is locked at the specified rotation angle. At this time, the position angle of the fan blade corresponds to the position angle of the guide track, so as to facilitate the cleaning of the fixed fan blade. The position angle of the guide track corresponds to the fan blade. The flip gear is installed on the rotating head, and the flip rack is installed on the left end of the guide track. The flip rack and the flip gear are temporarily meshed. The meshing rotation between the flip rack and the flip gear causes the rotating head to rotate ninety degrees.

The torsion piece and the extrusion block installed inside the slot are extruded. When the sleeve piece is inserted into the bottom of the cleaning roller, the torsion piece is inserted into the slot, and extrusion occurs between the torsion piece and the slot, thereby causing the torsion piece to rotate (the pitch of the spiral of the torsion piece is large, so that it can rotate under pushing and extrusion, and its principle is the same as that of the children's toy hand-pushed flying saucer).

[0016] Preferably, the oil injection module comprises an oil storage ring, an oil nozzle, a connecting shaft, a connecting hole, an oil storage cavity, a sliding frame, an inclined wedge block, and a piston plate.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0031] The embodiment of the present application discloses a ventilation device for an extra-long kilometer tunnel environment. The inhaled air is coarsely filtered and the filtering device is cleaned during the coarse filtration. For fine dust that cannot be filtered, a hidden cleaning module 9 is provided to maintain and clean the turbofan module 5, so as to avoid excessive accumulation of dust in the turbofan module 5, which restricts its rotation and affects the ventilation effect.

[0032] Reference Figure 1 , Figure 2As shown, a ventilation device for an extra-long kilometer tunnel environment includes a mounting base 1, an air outlet 2, an air inlet 3, a protective net 4, a turbofan module 5, a front filter module 6, a movable frame 7, a positioning module 8, a cleaning module 9, and an oil injection module 10. The left and right ends of the mounting base 1 are respectively provided with an air outlet 2 and an air inlet 3 for guiding the flow of wind. The protective net 4 is installed at the right end of the air inlet 3. The turbofan module 5 is arranged inside the mounting base 1. When the turbofan module 5 is working, it sucks air into the tunnel for ventilation. The front filter module 6 is arranged inside the air inlet 3. The front filter module 6 with a self-cleaning function performs primary filtering on the inhaled air. The movable frame 7 is arranged on the inner wall of the mounting base 1 by sliding left and right through an electric slider. The movable frame 7 and the turbofan module 5 are matched through the positioning module 8. The cleaning module 9 is evenly arranged on the inner wall of the mounting base 1. The cleaning module 9 with a self-cleaning function cleans the turbofan module 5. The oil injection module 10 is arranged in the movable frame 7. The oil injection module 10 performs multi-point touch oil injection maintenance on the turbofan module 5.

[0033] In the actual ventilation process, the turbofan module 5 performs suction work, and fresh air is sucked in under the guidance of the air inlet tube 3. The protective net 4 prevents large objects from entering the air inlet tube 3. The air entering the air inlet tube 3 is coarsely filtered under the action of the front filter module 6, and impurities such as particulate dust, paper pieces, and broken leaves are retained. At the same time, the front filter module 6 scrapes, shakes off, mixes and removes the retained impurities to prevent them from being blocked by impurities and affecting air entry. The coarsely filtered air is transported to the depth of the tunnel through the guidance of the air outlet tube 2 (when releasing air in the depth of the tunnel, it can be used in conjunction with the air purification equipment of the prior art to eliminate air Toxic substances, odors, etc. in the tunnel), after running for a specified time, the equipment is stopped for maintenance (for important sites, spare ventilation equipment is usually required to keep the ventilation in the tunnel smooth in special circumstances, such as machine maintenance, machine damage, etc.). At this time, the spare equipment can be enabled for ventilation, or maintenance work can be performed when no one is in the tunnel. The positioning module 8 fixes the position of the turbofan module 5, and then the cleaning module 9 performs dust cleaning on the turbofan module 5 with a fixed position (considering the cost issue, the cleaning module 9 can only clean part of the fan blades 53 inside the turbofan module 5 at a time, and it needs to be repeated Several cleaning actions are required to complete the cleaning of all the fan blades 53). At the same time, the oil injection module 10 injects lubricating oil into the turbofan module 5, and the impurities retained by the front filter module 6 are discharged from the side wall of the air outlet tube 2 (impurities such as dust, broken leaves, etc. retained in the front filter module 6 are easy to accumulate, so they need to be discharged in time to avoid clogging the channel). When the cleaning module 9 has finished cleaning, each mechanism is reset. During the reset process, the cleaning module 9 performs self-cleaning. After that, the rotating motor 51 drives the fan blades 53 to rotate a specified angle, and cleans the remaining fan blades 53 again. After all the fan blades 53 are cleaned, each structure is reset and the start The dynamic turbofan module 5 resumes ventilation work. The present application avoids the blockage of equipment caused by excessive impurities by coarsely filtering the air and scraping and shaking off the filtered impurities, as well as discharging them during maintenance. A targeted cleaning device is provided for the situation where excessive dust accumulation in the turbofan module 5 may cause unsmooth rotation. An oil injection module 10 is also provided to assist in the lubricating oil injection operation, thereby realizing automated maintenance, cleaning and maintenance of the turbofan module 5, so that the turbofan module 5 is maintained in good working condition, the air quality of the ventilation operation is maintained at a relatively stable level, and the ventilation operation runs longer and more stably.

The rotating motor 51 is installed inside the mounting base 1 through a motor base, and the output end of the rotating motor 51 is connected to the rotating hub 52, and the fan blades 53 are evenly installed on the outer periphery of the rotating hub 52.

[0035] During the actual operation, the rotating motor 51 drives the rotating hub 52 to rotate, and the fan blades 53 rotate along with the rotating hub 52 to generate wind force. Under the guidance of the air inlet tube 3, fresh air from the outside is sucked in.

[0036] Reference Figure 2 , Figure 5 As shown, the inhaled air may contain impurities such as debris and broken leaves. Therefore, the present application is provided with a front filter module 6 to perform coarse filtering of the air. The front filter module 6 includes a mounting frame 61, a metal filter screen 62, a scraper plate 63, a vibrating mechanism 64, a sliding cover plate 65, and a locking mechanism 66. The mounting frame 61 is arranged inside the air inlet cylinder 3 by rotating the electric turntable, and the metal filter screen 62 is slidably arranged on the mounting frame 61 left and right. The metal filter screen 62 of the prior art performs primary filtration on the air. The metal filter screen 62 has the advantages of large ventilation volume, large dust holding capacity, low initial resistance, and strong fireproof performance. Coarse dust particles in the air (and other impurities such as paper pieces, broken leaves, etc.) can be intercepted by the metal filter screen 62. A spring is connected between the metal filter screen 62 and the mounting frame 61, and the spring is coupled to the return spring. The scraper plate 63 is vertically installed on the inner wall of the air inlet cylinder 3, and the scraper plate 63 is in contact with the surface of the metal filter screen 62. When the metal filter screen 62 rotates, the scraper plate 63 scrapes the surface of the metal filter screen 62, thereby scraping off the impurities intercepted by the metal filter screen 62. The scraper plate 63 and the metal filter screen 62 are coordinated by a vibration mechanism 64. The vibration mechanism 64 makes the metal filter screen 62 vibrate, thereby facilitating the impurities intercepted by the metal filter screen 62 to fall off. The sliding cover plate 65 is slidably arranged left and right in the ash discharge port opened on the outer periphery of the lower end of the air inlet cylinder 3, and the ash discharge port is located directly below the metal filter screen 62.

The surface of the vibration plate 641 is evenly installed with striking blocks 642 from top to bottom. The striking blocks 642 are slid left and right in a through groove provided on the scraper plate 63. A second spring is connected between the striking block 642 and the through groove. The second spring plays a resetting role. Chamfered structures are provided at the upper and lower ends of the vibration plate 641. The extrusion piece 643 is evenly installed on the mounting frame 61. The extrusion piece 643 is provided with a chamfered structure. The extrusion piece 643 and the vibration plate 641 are extruded together.

[0038] In the actual filtering process, the mounting frame 61 is driven by the electric turntable to rotate, and the rotating mounting frame 61 drives the metal filter 62 to rotate together, and the air is filtered through the metal filter 62, and impurities are retained on the surface of the metal filter 62. The rotating metal filter 62 is in contact with the scraper plate 63, and the impurities retained on the surface of the metal filter 62 are scraped off by the scraper plate 63. At the same time, in the process of the rotation of the mounting frame 61, when the extrusion member 643 rotates to contact with the vibration plate 641, the extrusion member 643 squeezes the vibration plate 641 so that the vibration plate 641 moves toward the direction of the metal filter 62, and the striking block 642 moves with the vibration plate 641 to squeeze the metal filter 62 so that it is temporarily separated from the scraper plate 63. Afterwards, the extrusion piece 643 rotates to separate from the vibration plate 641, and the metal filter 62 is quickly reset under the action of spring 2 and hits the scraper plate 63. The impurities retained on the metal filter 62 are further shaken off, and the fallen impurities fall onto the sliding cover 65 in the ash discharge port. When performing maintenance, the locking mechanism 66 is unlocked, and the sliding cover 65 is opened at this time to allow the impurities in the ash discharge port to fall (garbage bags or the like can be placed under the ash discharge port in advance to hold the garbage, or clean up after the impurities fall).

The insertion piece 663 in the initial state is inserted into the insertion groove 664. At this time, the locking piece 665 is inserted into the locking groove 666 to lock the position between the locking block 1 661 and the locking block 2 662. The unlocking piece 667 is set to slide left and right on the outer periphery of the mounting seat 1. A spring four is connected between the unlocking piece 667 and the mounting seat 1. The spring four plays a resetting role. The left end of the unlocking piece 667 is extruded with the moving frame 7. The locking piece 665 is provided with an unlocking groove 668 which is extruded with the right end of the unlocking piece 667.

[0040] When unlocking is actually performed, the movable frame 7 moves to the right driven by the electric slider to squeeze the unlocking member 667, and the unlocking member 667 moves to the right to squeeze the unlocking groove 668 to make the locking member 665 move downward, and the locking member 665 moving downward disengages from the locking groove 666, thereby unlocking the position between the locking block 1 661 and the locking block 2 662. At this time, the sliding cover 65 can be pulled open by holding the handle 67 to allow impurities in the ash discharge port to fall out.

After the rotating hub 52 stops rotating, the clamping piece 82 and the docking piece 81 are squeezed to a specified rotation angle. At the same time, the position of the docking piece 81 is locked. Accordingly, the rotating hub 52 is locked at the specified rotation angle, which facilitates the cleaning of the fan blade 53 installed on the rotating hub 52.

[0042] During the actual positioning process, the movable frame 7 moves to the right driven by the electric slider so that the clamping member 82 squeezes the docking member 81. The clamping member 82 and the docking groove are squeezed so that the rotating hub 52 rotates to a certain extent, so that the clamping member 82 is inserted into the docking groove to lock the position of the rotating hub 52.

[0043] Reference Figure 7 , Fig. 9As shown, after long-term use, dust may accumulate on the surface of the fan blade 53, and the accumulated dust may easily cause a decrease in wind force. In order to clean the fan blade 53, the present application is provided with a cleaning module 9, which includes a connecting base 91, a rotating bracket 92, a rotating head 93, a cleaning roller 94, a guide rail 95, a flip gear 96, a flip rack 97, a rotating gear 98, a rotating rack 99, and a self-cleaning mechanism 910. The connecting base 91 is installed on the mobile frame 7, and the rotating bracket 92 is slidably arranged on the connecting base 91. A spring five is connected between the rotating bracket 92 and the connecting base 91, and the spring five plays a role in resetting and maintaining the stability of the rotating bracket 92 to prevent the rotating bracket 92 and the connecting base 91 from sliding at will. The rotating head 93 is rotatably arranged on the rotating bracket 92, and two cleaning rollers 94 are rotatably arranged on the bottom surface of the rotating head 93. The surface of the cleaning roller 94 is provided with a brush layer, and the brush layer plays a cleaning role. The guide rail 95 is installed on the inner wall of the mounting base 1. The track 95 corresponds to the position angle of the fan blade 53. After the clamping piece 82 and the docking piece 81 are squeezed and fitted, the rotating hub 52 is locked at the specified rotation angle. At this time, the position angle of the fan blade 53 corresponds to the position angle of the guide track 95, so as to facilitate the cleaning of the fixed position fan blade 53. The guide track 95 corresponds to the position angle of the fan blade 53. The flip gear 96 is installed on the rotating head 93, and the flip rack 97 is installed on the left end of the guide track 95. The flip rack 97 and the flip gear 96 are temporarily meshed. The meshing rotation between the flip rack 97 and the flip gear 96 causes the rotating head 93 to rotate ninety degrees. The rotating gear 98 is installed on the cleaning roller 94, and the rotating rack 99 is installed on the inner wall of the guide track 95. The rotating rack 99 and the rotating gear 98 are temporarily meshed. The meshing between the rotating gear 98 and the rotating rack 99 causes the cleaning roller 94 to rotate. The rotating cleaning roller 94 cleans the fan blade 53, and the self-cleaning mechanism 910 is arranged in the mounting seat 1.

[0044] During the actual cleaning process, the movable frame 7 moves to the right driven by the electric slider, and the connecting base 91 follows the movable frame 7 to move to the right. The engagement between the flip gear 96 and the flip rack 97 causes the rotating head 93 to rotate ninety degrees, and the cleaning roller 94 follows the rotating head 93 to rotate ninety degrees. Then, the connecting base 91 continues to move, and the cleaning roller 94 enters the guide rail 95 (at this time, the cleaning roller 94 is respectively located on both sides of the fan blade 53). After that, the cleaning roller 94 moves forward in the direction of the guide rail 95. At the same time, the rotating gear 98 is engaged with the rotating rack 99, so that the cleaning roller 94 rotates, and the rotating cleaning roller 94 cleans the fan blade 53.

[0045] Reference Fig.10As shown, when the cleaning roller 94 cleans the fan blade 53, some dust will be attached to it. In order to clean the cleaning roller 94, the present application is provided with a self-cleaning mechanism 910, which includes an arch frame 911, a comb roller 912, an extrusion block 1 913, an extrusion block 2 914, an extrusion block 3 915, a sleeve member 916, and a torsion member 917. The arch frame 911 is installed in the inner wall of the mounting seat 1, and the arch frame 911 corresponds to the position of the cleaning roller 94. The comb roller 912 is rotatably arranged on the arch frame 911. In the middle of the frame 911, the surface of the comb roller 912 is a metal tooth structure, which plays a combing role. When the cleaning roller 94 contacts and rotates with the comb roller 912, the metal teeth comb and clean the brush layer of the cleaning roller 94, thereby cleaning the brush layer. The extrusion block 1 913 is slidably arranged in the inner wall of the mounting seat 1. A spring 6 is connected between the extrusion block 1 913 and the mounting seat 1. The spring 6 plays a reset role. The extrusion block 2 914 is slidably arranged in the inner wall of the mounting seat 1 up and down, and the extrusion block 1 A spring 7 is connected between the pressure block 2 914 and the mounting seat 1, and the spring 7 plays a reset role. The extrusion block 3 915 is slidably arranged in the inner wall of the mounting seat 1. A spring 8 is connected between the extrusion block 3 915 and the mounting seat 1, and the spring 8 plays a reset role. The sleeve member 916 is installed on the extrusion block 3 915, and the sleeve member 916 corresponds to the cleaning roller 94 one by one. The bottom of the cleaning roller 94 is provided with a matching groove corresponding to the position of the sleeve member 916. The torsion member 917 is installed in the matching groove. The torsion member 917 It is a spiral twisted structure. A slot is provided in the middle of the sleeve member 916 to cooperate with the torsion member 917. The torsion member 917 and the extrusion block installed inside the slot are extruded. When the sleeve member 916 is inserted into the bottom of the cleaning roller 94, the torsion member 917 is inserted into the slot, and extrusion occurs between the torsion member 917 and the slot, so that the torsion member 917 rotates (the pitch of the spiral of the torsion member 917 is large, so that it can rotate under pushing and squeezing, and its principle is the same as that of the children's toy hand-pushed flying saucer).

[0046] During the actual self-cleaning process, the movable frame 7 moves to the left and resets, the cleaning roller 94 disengages from the guide track 95 and rotates ninety degrees to return to the arch frame 911, and then the movable frame 7 continues to move to the left (at this time, the flip gear 96 and the flip rack 97 have disengaged), and the movable frame 7 moving to the left contacts and squeezes the extrusion block 1 913. Under the action of the extrusion block 2 914, the extrusion block 3 915 is squeezed to move to the right, and the sleeve member 916 moves to the right. The sleeve member 916 moving to the right contacts the cleaning roller 94 moving to the left, and the torsion member 917 is inserted into the slot. Under the extrusion action, the torsion member 917 rotates, and the cleaning roller 94 rotates following the torsion member 917. The rotating cleaning roller 94 performs combing and dust removal under the action of the comb tooth roller 912. At the same time, the sleeve member 916 also limits the cleaning roller 94.

[0047] Reference Figure 3 As shown, the present application is provided with an oil injection module 10 for oil injection maintenance of the rotating motor 51, and the oil injection module 10 includes an oil storage ring 101, an oil injection nozzle 102, a connecting shaft 103, a connecting hole 104, an oil storage chamber 105, a sliding frame 106, an inclined wedge block 107, and a piston plate 108. The oil storage ring 101 is installed on the movable frame 7, and the oil storage ring 101 is sleeved on the outer periphery of the output end of the rotating motor 51. The oil injection nozzle 102 is rotated by the connecting shaft 103 and is arranged on The inner wall of the oil storage ring 101 is provided with a connecting hole 104 which passes through the inner wall of the connecting shaft 103. The connecting shaft 103 in the initial state seals the inside of the oil injection nozzle 102. When the oil injection nozzle 102 gradually rotates relative to the connecting shaft 103, the connecting hole 104 gradually rotates to a state of being connected to the inside of the oil injection nozzle 102. At this time, the oil injection nozzle 102 is unobstructed. A spring 9 is connected between the oil injection nozzle 102 and the inner wall of the oil storage ring 101. The spring 9 plays a reset role. The oil storage ring 101 is provided with an oil storage chamber 105, and an oil box is installed on the inner wall of the mounting seat 1. The oil box and the oil storage chamber 105 are connected through an oil pipeline. Lubricating oil for maintenance is stored in the oil box. The left end of the oil nozzle 102 is connected with the oil storage chamber 105 through an oil pipe. The sliding frame 106 is slidably arranged on the right end face of the oil storage ring 101, and a spring 10 is connected between the sliding frame 106 and the oil storage ring 101. The spring 10 plays a reset role. The inclined wedge block 107 is evenly installed on the sliding frame 106. The left end of the inclined wedge block 107 is an oblique angle structure. The inclined wedge block 107 corresponds to the position of the oil nozzle 102. The inclined wedge block 107 squeezes the oil nozzle 102 to make it rotate. The piston plate 108 is slidably arranged in the oil storage chamber 105, and the piston plate 108 is connected to the sliding frame 106 by a connecting rod. After the piston plate 108 is squeezed, the oil storage chamber 105 is pressurized, thereby facilitating the lubricating oil to be sprayed out.

[0048] During the actual oiling maintenance process, the movable frame 7 moves to the right driven by the electric slider, the sliding frame 106 contacts and squeezes the rotating hub 52, the piston plate 108 is squeezed to compress the internal space of the oil storage chamber 105, and the pressure increases. At the same time, the inclined wedge block 107 squeezes the oil nozzle 102 to rotate the oil nozzle 102, and the oil nozzle 102 contacts the shaft of the rotating motor 51. At the same time, the connecting hole 104 gradually rotates to a state of being connected to the inside of the oil nozzle 102 (the gap between the connecting hole 104 and the inside of the oil nozzle 102 is small, thereby avoiding excessive release of lubricating oil). Due to the increase in pressure inside the oil storage chamber 105, the lubricating oil is smoothly ejected from the oil nozzle 102 under the action of pressure, thereby adding lubricating oil to the shaft of the rotating motor 51 for maintenance.
