Description

Technical Field

[0001] This invention relates to the field of line installation technology, specifically to an iron accessory for power fittings. Background Technology

[0002] The iron or aluminum metal accessories widely used in power transmission lines are collectively referred to as hardware. Suspension clamps consist of a bracket, U-bolts, a clamp hull made of malleable cast iron, and a pressure plate. They are mainly used to fix conductors to insulator strings or lightning protection wires, support and distribute the stress on the conductors, and ensure the safe operation of power lines.

[0003] When suspension clamps are used in long-span transmission lines in terrains such as valleys, deep ditches, large rivers, lakes, and straits, the tension on the suspension clamps is significant due to the large conductor span. Furthermore, these terrains increase the frequency of wind speed and direction changes. Under wind force, relative motion occurs between the suspension clamp's hull and the mounting plate. The mounting plate swings at a small angle around the hull's axis, causing grooves to form on the hull's axis. Over time, these grooves deepen, and when they reach a certain depth, the strength of the hull's axis is greatly reduced, eventually causing the hull to fall from the suspension clamp and cause an accident. Therefore, technicians need to conduct regular comprehensive inspections of the suspension clamps.

[0004] Existing suspension clamps typically have two mutually perpendicular shafts, allowing the hull to swing in two horizontal directions. When the cable drives the hull to vibrate up and down, the lack of space for vertical movement can easily cause deformation of the connecting parts, thus affecting the service life of the suspension clamp. Furthermore, the lack of lubrication between the shafts and the connecting parts, coupled with the significant pressure between them, leads to accelerated wear at the contact points, necessitating more frequent inspections and increasing the workload of technicians. If the suspension clamp is already deeply worn before the designated inspection time, it poses a certain danger. Therefore, adding lubricating oil is necessary to reduce wear.

[0005] However, the existing suspension clamps have poor lubrication between the hanger shaft and the hanger plate. Due to the large pressure between the hanger plate and the hanger shaft, the lubricating oil at the contact surface of the hanger shaft and the hanger plate is in a high-pressure environment. The high pressure causes the wear of the contact parts between the hanger shaft and the hanger plate to be accelerated, generating wear particles. These particles mix into the lubricating oil, forming abrasive contamination, which further accelerates the aging and failure of the lubricating oil. When the lubricating oil fails, the wear of the hanger shaft on the hull deepens rapidly in a short period of time, so that the inspection frequency needs to be increased, which increases the workload of the staff. If the suspension clamp is already in a deep wear state before the specified inspection time, it is dangerous. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an iron accessory for power fittings, solving the problem that wear particles affect the lubrication effect of lubricating oil during use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an iron accessory for power fittings, comprising two semi-circular hulls, a hanging plate, and a fixing base.

[0012] A telescopic rod is fixedly connected to the center of one of the two side plates. The telescopic rod penetrates the central layer, and an annular counterweight is provided on the outer side of the center of the telescopic rod. The two ends of the counterweight are fixedly connected to the inner wall of the central layer. A three-way pipe is fixedly provided at the bottom of the drain end.

[0013] A flow tube is fixedly installed on the lower inner wall of the central layer to connect two liquid storage chambers. A vertically arranged chamber is opened inside the flow tube. A sealing block is slidably connected inside the chamber. An elastic element is fixedly connected to the upper surface of the sealing block, and the top of the elastic element is fixedly connected to the top wall of the chamber. A magnetic block is embedded below the sealing block. An opening is opened on the lower surface of the central layer corresponding to the magnetic block. A magnetic block with magnetic repulsion is arranged below the magnetic block. The magnetic block is fixedly installed on the inner bottom wall of the fixed base.

[0014] The buffer includes a buffer airbag, and a support frame is fixedly connected to the side of the buffer airbag away from the side plate. The bottom end of the support frame is fixedly connected to the inner bottom wall of the fixed seat.

[0015] The side wall of the buffer airbag is fixedly provided with an air outlet, and the air outlet is fixedly provided with a valve and a one-way valve. The side wall of the buffer airbag is fixedly provided with an air inlet pipe, and the end of the air inlet pipe away from the buffer airbag is fixedly connected to a rotary joint. The side wall of the liquid storage chamber is provided with a threaded air outlet that is threadedly connected to the rotary joint. An oil and gas filter membrane is provided inside the threaded air outlet, and a one-way valve is fixedly provided on the air inlet pipe.

[0016] The lower side wall of the buffer airbag is fixedly provided with an air intake chamber. The bottom of the air intake chamber is open, and a T-shaped sealing head is slidably connected inside the air intake chamber. The side wall of the air intake chamber is provided with two air intake ports that are connected to the buffer airbag. A limiting protrusion is provided between the two air intake ports, and the limiting protrusion is fixedly provided inside the air intake chamber.

[0017] The buffer airbag includes a plate body one and a plate body two. An annular bladder body is fixedly provided on the opposite side of the plate body one and the plate body two. Several T-shaped support rods are fixedly connected to the side wall of the plate body one, and the support rods penetrate the plate body two. An elastic element two is sleeved on the surface of the support rods. A trapezoidal inclined block is fixedly connected to the lower side wall of the plate body one.

[0018] Working principle: The mounting base is fixed in the designated position, and then the cable is fixed by the two closed clamps. When encountering horizontal wind force, the built-in bearings one and two can make the cable rotate left and right in the vertical direction or back and forth in the horizontal direction, thereby reducing the impact of wind force. When the lubricating oil passes through the flow end, it enters the feed cylinder and filter cylinder through the inlet, and is discharged after being filtered by the filter cylinder. This allows particulate impurities to remain inside the filter cylinder. The filter cylinder filters the particles in the lubricating oil, avoiding the problem of abrasive contamination caused by wear particles, which accelerates the aging and failure of the lubricating oil, and improves the repeated lubrication effect of the lubricating oil.

[0019] This invention provides an iron accessory for power fittings. It has the following beneficial effects:

[0020] 1. In this invention, the built-in bearings one and two can rotate the line in multiple directions when encountering horizontal wind force, thereby reducing the impact of wind force. The lubrication component can add lubricating oil to bearings one and two to increase lubrication, reduce friction, and reduce the wear of bearings. The filter component can filter particles in the lubricating oil to avoid the problem of abrasive contamination caused by wear particles, which accelerates the aging and failure of lubricating oil and improves the repeated lubrication effect of lubricating oil.

[0021] 2. In this invention, when the upper shell is continuously swaying due to wind, it drives the gear to move along the rack, causing the gear to rotate and drive the filter cartridge to rotate. When the filter cartridge rotates, it generates centrifugal force, which can accelerate the ejection of lubricating oil and improve the filtration efficiency of the lubricating oil.

[0022] 3. In this invention, when the upper housing swings due to wind, it drives the liquid storage chamber on the front side of the swing direction to move towards the buffer, thereby squeezing the liquid storage chamber and squeezing the lubricating oil inside the liquid storage chamber into the nozzle one and nozzle two and spraying it out, thereby adding lubricating oil to the inside of bearing one and bearing two for automatic lubrication.

[0023] 4. In this invention, when the liquid storage chamber rotates, it collides with the buffer airbag on the front side of the rotation direction. While the buffer airbag compresses the liquid storage chamber and deforms it, it can also deform itself, which has a certain buffering effect and reduces the impact force when the liquid storage chamber rotates.

[0045] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0046] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an iron accessory for power fittings, comprising two semi-circular hulls 1, a hanging plate 2, and a fixing base 3. A hanging shaft 4 is fixedly connected to the side wall of the fixing base 3. The hanging plate 2 includes an upper housing 21, with U-shaped rods 22 extending through both sides of the upper housing 21. A connecting rod 25 is slidably connected to the bottom end of each rod 22, and one end of the connecting rod 25 is fixedly connected to the hull 1. One end of the hanging shaft 4 extends into the interior of the upper housing 21, and the hanging shaft 4 rotates with the upper housing 21 via a bearing 5. The connecting rod 22 is rotatably connected to the upper housing 21 via bearing 6. The bottom end of the upper housing 21 is fixedly connected to a drain end 23. Below the drain end 23, a lubrication assembly 8 storing lubricating oil is provided. The lubrication assembly 8 is used to add lubricating oil to bearing 5 and bearing 6. A horizontally arranged filter chamber is opened inside the drain end 23. A filter assembly 7 is installed inside the filter chamber. The filter assembly 7 includes a filter element 71, which includes a filter cartridge 712. The filter cartridge 712 is rotatably installed inside the filter chamber.

[0047] Specifically, the mounting base 3 is fixed in the designated position. By sliding the connecting rods 25 to both sides, the hull 1 is opened so that the line can be placed on the hull 1. Then, the two hulls 1 are closed to clamp and fix the line. When encountering horizontal wind, the built-in bearings 5 ​​and 6 can make the line rotate left and right in the vertical direction or back and forth in the horizontal direction, thereby reducing the impact of the wind. Lubricating oil can be added to bearings 5 ​​and 6 through the lubrication assembly 8 to increase lubrication, reduce friction, and reduce the wear of the bearings. After the lubricating oil is added, it flows back to the lubrication assembly 8 through the drain end 23 to achieve the effect of reuse. When the lubricating oil passes through the drain end 23, the filter cartridge 712 filters the particles in the lubricating oil to avoid the problem of abrasive contamination caused by wear particles, which accelerates the aging and failure of the lubricating oil and improves the repeated lubrication effect of the lubricating oil.

[0048] Please see the appendix Figure 4 - Appendix Figure 5 One end of the filter cartridge 712 is rotatably connected to the feed cylinder 711. The feed cylinder 711 has a liquid inlet at the top center and is fixedly installed inside the filter chamber. The side wall of the drain end 23 has a cleaning port corresponding to the feed cylinder 711. An I-shaped cleaning component 9 is inserted into the cleaning port and is detachably and securely connected to the drain end 23 by bolts.

[0049] Specifically, when the lubricating oil passes through the drain end 23, it enters the feed cylinder 711 and the filter cylinder 712 through the inlet. After being filtered by the filter cylinder 712, it is discharged, causing particulate impurities to remain inside the filter cylinder 712. During maintenance, the particulate impurities inside the filter cylinder 712 can be scraped off simultaneously by pulling out the cleaning part 9, which achieves the effect of cleaning the filter cylinder 712 and discharging impurities.

[0050] Please see the appendix Figure 4 - Appendix Figure 5 The filter assembly 7 also includes a connecting rod 72. One end of the connecting rod 72 passes through the filter chamber and is fixedly connected to the filter cartridge 712. The other end of the connecting rod 72 is fixedly connected to a gear 73. The tooth end of the gear 73 meshes with an arc-shaped rack 74. An arc-shaped connecting frame 75 is fixedly connected below the rack 74. The side wall of the connecting frame 75 is fixedly connected to the fixed seat 3. Several outer scrapers 713 are fixedly connected to the outer wall of the filter cartridge 712. An inner scraper 714 is fixedly connected to the lower surface of the cleaning component 9. The inner scraper 714 fits against the inner wall of the filter cartridge 712. In order to reduce the wear of the gear 73 and the rack 74, an arc-shaped oil reservoir for storing lubricating oil can be provided on the outside of the gear 73 and the rack 74 to lubricate them.

[0051] Specifically, when the upper housing 21 continuously swings due to wind, it drives the gear 73 to move along the rack 74, thereby causing the gear 73 to rotate during movement. This rotation, in turn, drives the filter cartridge 712 to rotate via the connecting rod 72. The centrifugal force generated by the rotation of the filter cartridge 712 can accelerate the ejection of lubricating oil, thereby improving the filtration efficiency of the lubricating oil. At the same time, the inner scraper 714 cleans the rotating filter cartridge 712, causing particulate impurities to accumulate at the bottom of the filter cartridge 712. Meanwhile, the outer scraper 713 can assist in the rapid discharge of lubricating oil from the filter chamber. When the lubricating oil is ejected upwards from the inner wall of the filter chamber, it can be discharged downwards under the action of the rotating outer scraper 713, preventing it from falling back into the filter cartridge 712.

[0052] Please see the appendix Figure 6 - Appendix Figure 7 The lubrication assembly 8 includes a hollow central layer 81, an annular nozzle 86, two sets of annular nozzles 84, and two sets of buffer components 85. Liquid storage chambers 82 are respectively provided on both sides of the central layer 81. Each liquid storage chamber 82 includes a bellows 821 made of elastic materials such as silicone, nitrile rubber, or thermoplastic elastomers, which can automatically expand under pressure. One end of the bellows 821 is fixedly connected to the central layer 81, and the other end is fixedly connected to a side plate 822. Nozzle 86 is fixedly installed on the outer wall of the hanging shaft 4, facing the bearing 5. Nozzle 84 is fixedly installed on the inner wall of the upper housing 21, corresponding to the bearing 6. Oil supply pipes 825 are fixedly provided on the side plate 822, connecting to nozzles 86 and 84 respectively. The liquid storage chamber 82 can be connected to a single nozzle 84 via the oil supply pipes 825. The lubricating oil is connected to two nozzles 84 via two oil supply pipes 825. A one-way valve is fixedly installed at one end of the oil supply pipe 825 near nozzle 86 and nozzle 84. The one-way valve is used to control the lubricating oil in the oil supply pipe 825 to flow into the nozzle in one direction, preventing the lubricating oil in the nozzle from flowing back. The buffer 85 is installed on the lower side of the fixed base 3. A three-way pipe 24 is fixedly installed at the bottom of the drain end 23. The three ends of the three-way pipe 24 pass through and are fixedly connected to the central layer 81. The two ends of the lower side of the three-way pipe 24 are connected to the two liquid storage chambers 82. A one-way valve is fixedly installed at one end of the upper side of the three-way pipe 24. The one-way valve is used to control the lubricating oil in the three-way pipe 24 to flow downward in one direction. After the lubricating oil flows back, the one-way valves 1 and 2 close, so that the inside of the liquid storage chamber 82 remains relatively closed, improving the storage effect of the lubricating oil in the liquid storage chamber 82.

[0053] Specifically, the retractable bellows 821 allows the side plate 822 to expand and cooperate with the central layer 81 to compress the bellows 821, thereby squeezing out the lubricating oil inside the bellows 821. The lubricating oil is stored in the reservoir 82. When the upper shell 21 swings due to wind, it moves the reservoir 82 on the front side of the swing direction towards the buffer 85. The buffer 85 then squeezes the reservoir 82, forcing the lubricating oil inside the reservoir 82 into the nozzle 1 86 and nozzle 2 84 through the oil supply pipe 825 and spraying it out. This adds lubricating oil to the interior of bearing 1 5 and bearing 2 6, achieving automatic lubrication of bearing 1 5 and bearing 2 6. Subsequently, excess lubricating oil is collected inside the upper shell 21 and flows back to the reservoir 82 through the drain end 23 and the three-way pipe 24. When passing through the two sets of reservoirs 82 on the left and right sides of the central layer 81, the upper shell 21 can squeeze out lubricating oil whether it rotates to the left or right under the action of wind.

[0054] Please see the appendix Figure 7 A telescopic rod 823 is fixedly connected to the center of opposite sides of the two side plates 822. The telescopic rod 823 penetrates the central layer 81, and an annular counterweight 824 is provided on the outer side of the center of the telescopic rod 823. The two ends of the counterweight 824 are fixedly connected to the inner wall of the central layer 81. The telescopic rod 823 includes an outer cylinder and an inner rod. The side wall of the central layer 81 near the outer cylinder has an opening with the same diameter as the outer cylinder for the outer cylinder to pass through. An annular... The protrusion is used to limit the outer cylinder when the liquid storage chamber 82 near the inner rod is squeezed, so as to prevent the outer cylinder from exiting the central layer 81. The central layer 81 has an opening with the same diameter as the annular protrusion on the side near the inner rod so that the annular protrusion can pass through when the liquid storage chamber 82 near the outer cylinder is squeezed. A sealing ring is fixedly installed inside the counterweight 824 near the outer cylinder to seal the gap between the counterweight 824 and the outer cylinder, so as to prevent lubricating oil from flowing through the counterweight 824.

[0055] Specifically, the counterweight 824 is used to prevent lubricating oil from flowing into the central layer 81 through the gap where the telescopic rod 823 intersects with the central layer 81. At the same time, the counterweight 824 applies downward gravity to the drain end 23, so that when the liquid volume inside the two sets of liquid storage chambers is different, the drain end 23 can still remain vertical in a windless state under the gravity of the counterweight 824. The telescopic rod 823 provides support for the side plate 822 to prevent it from tilting downward and restricts the direction of movement of the side plate 822.

[0056] Example 2: Please refer to the appendix. Figure 8Since the lubricating oil in a single reservoir 82 flows to both reservoirs 82 after being squeezed out, the amount of lubricating oil in the two reservoirs 82 will be different. As a result, when a single reservoir 82 is subjected to repeated squeezing, all the lubricating oil inside will be squeezed out, while the other reservoir 82 will store too much lubricating oil, resulting in uneven distribution of lubricating oil and affecting its lubrication effect. Therefore, this embodiment provides the following technical solution to solve the above problems: a flow pipe 83 is fixedly provided on the lower inner wall of the central layer 81 to connect the two reservoirs 82.

[0057] Specifically, the flow pipe 83 is used to supply lubricating oil to the two reservoirs 82, so that the lubricating oil in the two reservoirs 82 can remain relatively uniform under hydraulic action.

[0058] Example 3: Please refer to the appendix. Figure 8 When the reservoir 82 is compressed, some lubricating oil will flow out through the flow pipe 83, thus affecting the amount of lubricating oil added. Therefore, this embodiment provides the following technical solution to solve the above problem: a vertically arranged chamber 831 is opened inside the flow pipe 83, and a sealing block 832 is slidably connected inside the chamber 831. An elastic element 833 is fixedly connected to the upper surface of the sealing block 832. The elastic element can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., and the top of the elastic element 833 is flush with the top wall of the chamber 831. The sealing block 832 is fixedly connected, and a magnetic block 834 is embedded below it. An opening is provided on the lower surface of the central layer 81 corresponding to the magnetic block 834. A magnetic block 835 with magnetic repulsion is provided below the magnetic block 834. The magnetic block 835 is fixedly installed on the inner bottom wall of the fixed base 3. The flow tube 83 is made of non-magnetic shielding material, and the central layer 81 is made of magnetic shielding material to block the magnetic force of the magnetic blocks 834 and 835. The magnetic force is generated when the magnetic blocks 834 and 835 are linearly distributed with the opening.

[0059] Specifically, when the central layer 81 rotates, the first magnetic block 834, the second magnetic block 835, and the opening are misaligned. At this time, the sealing block 832 slides down to the bottom of the chamber 831 through the elasticity of the first elastic element 833, thereby blocking the flow pipe 83. This prevents lubricating oil from flowing out of the flow pipe 83 when the liquid storage chamber 82 is squeezed. When the central layer 81 stops rotating, it remains relatively vertical due to the influence of the counterweight 824. At this time, the first magnetic block 834 and the second magnetic block 835 are linearly distributed with the opening. Through the magnetic repulsion of the first magnetic block 834 and the second magnetic block 835, the sealing block 832 slides upward, thereby opening the flow pipe 83 and allowing the lubricating oil to flow through the flow pipe 83.

[0060] Please see the appendix Figure 7Based on the above embodiments, the buffer 85 includes a buffer airbag 851, and a support frame 852 is fixedly connected to the side of the buffer airbag 851 away from the side plate 822. The bottom end of the support frame 852 is fixedly connected to the inner bottom wall of the fixed seat 3.

[0061] Specifically, when the liquid storage chamber 82 rotates, it collides with the buffer airbag 851 on the front side of the rotation direction. While the buffer airbag 851 compresses the liquid storage chamber 82 to deform it, it can also deform itself, which has a certain buffering effect and reduces the impact force when the liquid storage chamber 82 rotates. The support frame 852 is used to support the buffer airbag 851.

[0062] Please see the appendix Figure 9 - Appendix Figure 11 A gas outlet 853 is fixedly installed on the side wall of the buffer airbag 851, and a valve and a one-way valve are fixedly installed on the gas outlet 853. The one-way valve is used to control the gas inside the gas outlet 853 to be discharged from the buffer airbag 851 to the outside in one direction. An air inlet pipe 854 is fixedly installed on the side wall of the buffer airbag 851, and a rotary joint 855 is fixedly connected to the end of the air inlet pipe 854 away from the buffer airbag 851. A threaded gas outlet is opened on the side wall of the liquid storage chamber 82, which is threadedly connected to the rotary joint 855. An oil-gas filter membrane 856 is installed inside the threaded gas outlet. During maintenance, the rotary joint 855 can be unscrewed and disassembled to replace the oil-gas filter membrane 856. A one-way valve 10 is fixedly installed on the air inlet pipe 854. The opening and closing size of the gas outlet 853 can be adjusted by the valve to control the airflow discharge efficiency of the gas outlet 853 and adjust the buffer airbag 851. The cushioning force of the airbag 851 is provided by the one-way valve 10, which includes a convex valve cavity 101. A sealing plate 102 is provided inside the valve cavity 101. An elastic element 103 is fixedly connected to the side wall of the sealing plate 102, and the other end of the elastic element 103 is fixedly connected to the inner side wall of the valve cavity 101. Except for the one-way valve 10, all the one-way valves in this application are spring-type one-way valves. When the airbag 851 is compressed, the airflow pushes the sealing plate 102 against the inner side wall of the valve cavity 101 when passing through the valve cavity 101, thereby closing the valve cavity 101 and preventing the airbag 851 from being discharged through the one-way valve 10. When the airflow stops, the sealing plate 102 is no longer in contact with the valve cavity 101 due to the elastic force of the elastic element 103, thereby opening the valve cavity 101 and allowing air to flow into the airbag 851 through the one-way valve 10.

[0063] Specifically, when the buffer airbag 851 is compressed, the gas inside it is slowly discharged from the air outlet 853. When the buffer airbag 851 rebounds, the air inlet pipe 854 can create a negative pressure inside the connected liquid storage chamber 82. After the oil and gas are separated by the oil-gas filter membrane 856, the gas is drawn into the buffer airbag 851 to replenish the gas flowing out of the buffer airbag 851 and reduce the amount of air inside the liquid storage chamber 82. This helps to squeeze out the lubricating oil when the amount of lubricating oil inside the liquid storage chamber 82 is small, and at the same time, it can reduce the oxidation of the lubricating oil inside the liquid storage chamber 82 to a certain extent.

[0064] Please see the appendix Figure 10 The buffer airbag 851 includes a first plate 8511 and a second plate 8512. An annular bladder 8513 is fixedly provided on the opposite side of the first plate 8511 and the second plate 8512. Several T-shaped support rods 8514 are fixedly connected to the side wall of the first plate 8511, and the support rods 8514 penetrate the second plate 8512. An elastic element 8515 is sleeved on the surface of the support rods 8514. A trapezoidal inclined block 8516 is fixedly connected to the lower side wall of the first plate 8511.

[0065] Specifically, the support frame 852 supports the second plate 8512, the support rod 8514 supports and guides the first plate 8511, and the elastic element 8515 can assist the buffer airbag 851 in rapidly inhaling and expanding.

[0066] Example 4: Please refer to the appendix. Figure 10 When the gas inside the liquid storage chamber 82 is insufficient, the buffer airbag 851 cannot be replenished effectively. To solve the above problem, this embodiment provides the following technical solution: an air intake chamber 857 is fixedly provided on the lower side wall of the buffer airbag 851. The bottom of the air intake chamber 857 is open, and a T-shaped sealing head 858 is slidably connected inside the air intake chamber 857. The side wall of the air intake chamber 857 has two air intake ports that communicate with the buffer airbag 851. A limiting protrusion is provided between the two air intake ports. The limiting protrusion is fixedly provided inside the air intake chamber 857 and is used to limit the rising height of the sealing head 858. A dust filter screen can be fixedly provided at the bottom of the air intake chamber 857 to filter dust and impurities.

[0067] Specifically, initially, the sealing head 858 slides to the bottom of the suction chamber 857, blocking the lower suction port, thus closing the suction chamber 857 and preventing gas from leaking out of the buffer airbag 851. When the buffer airbag 851 is compressed to its minimum size due to lack of gas, the plate 8511 moves the inclined block 8516 below the sealing head 858, thereby lifting the sealing head 858 and opening the lower suction port, allowing the buffer airbag 851 to draw in outside air, inflate, and recover. When the buffer airbag 851 is compressed again, the airflow inside the buffer airbag 851 will cause the sealing head 858 to descend when it is ejected from the upper air intake port, thereby automatically closing the air intake port again. This achieves the effect of automatically opening and closing the air intake chamber 857 according to the deformation range of the buffer airbag 851. Furthermore, when the buffer airbag 851 is compressed to its minimum range under a large impact force, the lower air intake port can also be opened to assist the airflow inside the buffer airbag 851 in being discharged, which helps to prevent the buffer airbag 851 from being damaged by excessive instantaneous impact force.

[0068] Workflow: Fix the mounting base 3 in the designated position, and fix the line by closing the clamp. When encountering horizontal wind force, the built-in bearing 5 and bearing 6 can make the line rotate left and right in the vertical direction or back and forth in the horizontal direction, thereby reducing the impact of wind force. When the upper shell 21 swings due to wind force, it drives the liquid storage chamber 82 on the front side of the swing direction to move towards the buffer 85. The buffer 85 squeezes the liquid storage chamber 82, and the lubricating oil inside the liquid storage chamber 82 is squeezed into the nozzle 86 and nozzle 84 through the oil supply pipe 825 and sprayed out, thereby adding lubricating oil to the inside of bearing 5 and bearing 6, achieving the effect of automatic lubrication of bearing 5 and bearing 6. Then, the excess lubricating oil is collected inside the upper shell 21 and flows back to the liquid storage chamber 82 through the drain end 23 and the three-way pipe 24. When passing through the two sets of liquid storage chambers 82 on the left and right sides of the central layer 81, the upper shell 21 can squeeze out lubricating oil whether it rotates to the left or right under the action of wind force.

[0069] When the lubricating oil passes through the flow end, it enters the feed cylinder 711 and the filter cylinder 712 through the inlet. After being filtered by the filter cylinder 712, it is discharged, causing particulate impurities to remain inside the filter cylinder 712. During maintenance, the particulate impurities inside the filter cylinder 712 can be scraped off simultaneously by pulling out the cleaning part 9, which achieves the effect of cleaning the filter cylinder 712 and discharging impurities. When the upper housing 21 is continuously oscillating due to the wind, it drives the gear 73 to move along the rack 74, thereby causing the gear 73 to rotate when moving. This rotation drives the filter cylinder 712 to rotate through the connecting rod 72. The centrifugal force generated when the filter cylinder 712 rotates can accelerate the ejection of lubricating oil and improve the filtration efficiency of the lubricating oil.

[0070] When the liquid storage chamber 82 rotates, it collides with the buffer airbag 851 on the front side of the rotation direction. As the buffer airbag 851 compresses the liquid storage chamber 82 and deforms, it can also deform itself, which has a certain buffering effect and reduces the impact force when the liquid storage chamber 82 rotates. When the buffer airbag 851 is compressed, the gas inside it is slowly discharged from the air outlet 853. When the buffer airbag 851 rebounds, the air inlet pipe 854 can form a negative pressure inside the connected liquid storage chamber 82. After the oil and gas are separated by the oil and gas filter membrane 856, the gas is drawn into the buffer airbag 851 to replenish the gas flowing out of the buffer airbag 851 and reduce the amount of air inside the liquid storage chamber 82. This helps to squeeze out the lubricating oil when the amount of lubricating oil inside the liquid storage chamber 82 is small, and at the same time, it reduces the oxidation of the lubricating oil inside the liquid storage chamber 82 to a certain extent.
