Description

Technical Field

[0001] This utility model relates to the technical field of camera condenser equipment, specifically to a bearing lubrication structure for camera condensers. Background Technology

[0002] A synchronous condenser is a special type of synchronous motor mainly used in power systems to regulate voltage, improve power factor, and ensure the stable operation of the power system.

[0003] When using a synchronous condenser bearing, it is necessary to add lubricating oil regularly. The purpose of lubrication is to provide a stable lubricating fluid for the bearing, reduce frictional loss on the bearing contact surfaces, and dissipate the heat generated by friction. Traditionally, when adding lubricating oil to a synchronous condenser, the cover at the oil filling hole is usually opened first, and then the lubricating oil is manually added to the inside of the condenser through the oil filling hole. This manual method not only leads to inaccurate lubrication but also to untimely lubrication. Manual lubrication depends on the inspection cycle of maintenance personnel. If lubrication is delayed due to personnel negligence or scheduling delays, the bearing will continue to operate in a lubrication-deficient state, which may cause serious damage in a short period of time, significantly shorten the bearing's service life, and increase equipment maintenance costs and workload. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a bearing lubrication structure for a camera condenser.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bearing lubrication structure for a synchronous condenser, comprising a synchronous condenser body, a storage cylinder, a timer, and an electric telescopic rod. The upper end of the synchronous condenser body is provided with a top plate and an oil injection hole penetrating the top plate. The storage cylinder is located at the upper end of the top plate, and the bottom end of the storage cylinder is provided with an oil outlet pipe inserted into the top plate. The electric telescopic rod is fixed at the upper end of the storage cylinder, and the output end of the electric telescopic rod is provided with a lifting rod inserted into the storage cylinder. The bottom end of the lifting rod is provided with an injection plug located inside the storage cylinder, and the periphery of the injection plug is tightly fitted to the inner wall of the storage cylinder. The timer is fixed at the upper end of the top plate, and the timer and the electric telescopic rod are connected by an electrical signal.

[0008] To prevent the lubricating oil in the storage cylinder from dripping at the oil outlet pipe, the present invention includes an improvement where the inner wall of the oil outlet pipe is provided with multiple rubber seals that fit together, and all of the rubber seals are fan-shaped.

[0009] To facilitate the assembly of the storage cylinder and the first annular seat, the present invention includes the following improvements: the upper end of the top plate is provided with a first annular seat, the lower end of the first annular seat is provided with a first cylinder body that is inserted into the oil injection hole and threadedly connected to the oil injection hole, the bottom of the storage cylinder is provided with a second cylinder body that passes through the first annular seat and is threadedly connected to the first annular seat, the oil outlet pipe is located at the lower end of the second cylinder body, the top of the second cylinder body is provided with a second annular seat, and the second annular seat fits against the upper end of the first annular seat.

[0010] Furthermore, an improvement of this utility model is that the storage cylinder, the second cylinder body, the second annular seat, and the oil outlet pipe are integrated into a single structure.

[0011] Furthermore, an improvement of this utility model is that anti-slip textures are provided on the outer walls of both the first annular seat and the second annular seat.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a bearing lubrication structure for a camera condenser, which has the following beneficial effects:

[0015] Achieving automated and precise lubrication:

[0016] By linking the timer with the electric telescopic rod, the traditional manual lubrication method can be replaced. The lubrication cycle can be preset according to the bearing's operating requirements, ensuring timely and accurate lubrication. This avoids problems of "over-lubrication" or "under-lubrication" caused by human error, effectively reducing bearing friction loss.

[0017] Improve lubrication stability and sealing performance:

[0018] The storage cylinder adopts a syringe-like push structure, which, together with the injection stopper that fits tightly against the inner wall, can stably control the output pressure of the lubricating oil. The fan-shaped rubber seal inside the oil outlet automatically closes when not injecting oil to prevent lubricating oil from dripping and contaminating the equipment. When injecting oil, it naturally opens with the pressure to ensure smooth oil passage, taking into account both sealing and flow. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 The present invention discloses a bearing lubrication structure for a camera condenser, comprising a camera condenser body 1, a storage cylinder 6, a timer 16, and an electric telescopic rod 9. The upper end of the camera condenser body 1 is provided with a top plate 2 and an oil injection hole 4 penetrating the top plate 2. The storage cylinder 6 is located at the upper end of the top plate 2, and the bottom end of the storage cylinder 6 is provided with an oil outlet pipe 11 inserted into the top plate 2. The electric telescopic rod 9 is fixed at the upper end of the storage cylinder 6, and the output end of the electric telescopic rod 9 is provided with a lifting rod inserted into the storage cylinder 6. The bottom end of the lifting rod is provided with an injection plug 10 located inside the storage cylinder 6, and the periphery of the injection plug 10 is tightly fitted with the inner wall of the storage cylinder 6. The timer 16 is fixed at the upper end of the top plate 2, and the timer 16 is connected to the electric telescopic rod 9 by an electrical signal.

[0026] The storage cylinder 6, the second cylinder 7, the second annular seat 8, and the oil outlet pipe 11 are an integrated structure.

[0027] The outer walls of both the first annular seat 3 and the second annular seat 8 are provided with anti-slip textures.

[0028] Structural assembly:

[0029] The top plate 2 has a first annular seat 3 at its upper end. The lower end of the first annular seat 3 has a first cylindrical body 5 that is inserted into the oil injection hole 4 and threadedly connected to the oil injection hole 4. The bottom of the storage cylinder 6 has a second cylindrical body 7 that passes through the first annular seat 3 and is threadedly connected to the first annular seat 3. The oil outlet pipe 11 is located at the lower end of the second cylindrical body 7. The top of the second cylindrical body 7 has a second annular seat 8 that fits against the upper end of the first annular seat 3.

[0030] The inner wall of the oil outlet pipe 11 is provided with a plurality of rubber sealing pieces 12 that fit together with each other, and the plurality of rubber sealing pieces 12 are all fan-shaped structures.

[0031] The first annular seat 3 is threadedly connected to the oil injection hole 4 on the top plate 2 of the camera body 1 via the first cylinder 5 at its lower end, so that the rubber tube 14 at the lower end of the annular frame 13 is inserted into the oil injection hole 4.

[0032] Next, the second cylinder 7 at the bottom of the storage cylinder 6 is threaded through the first annular seat 3 and connected to it until the second annular seat 8 is attached to the upper end of the first annular seat 3, thus completing the fixing of the storage cylinder 6 and the top plate 2.

[0033] At this time, the oil outlet pipe 11 at the bottom of the storage cylinder 6 is precisely connected to the oil injection hole 4 channel, and the internal fan-shaped rubber sealing plates 12 adhere to each other due to their own elasticity, forming a sealed state.

[0034] Material preparation:

[0035] If lubricating oil needs to be added to the storage cylinder 6, the second annular seat 8 can be rotated (using its outer anti-slip texture to facilitate the application of force) to remove the entire storage cylinder 6 from the first annular seat 3. After adding lubricating oil, it can be reassembled and reset to ensure that the injection stopper 10 fits tightly against the inner wall of the storage cylinder 6.

[0036] Automatic lubrication operation:

[0037] When the synchronous condenser is running, the timer 16 on the top plate 2 starts timing. When the preset lubrication cycle is reached, the timer 16 triggers the electric telescopic rod 9 to start via an electrical signal. Its output end drives the lifting rod to move downward, pushing the injection plug 10 to move down synchronously in the storage cylinder 6. At this time, the lubricating oil in the storage cylinder 6 is under pressure, pushing open the fan-shaped rubber seal 12 in the oil outlet pipe, so that the lubricating oil flows precisely into the bearing part of the synchronous condenser body 1 through the oil outlet pipe 11, the oil injection hole 4 and the rubber tube 14.

[0038] Stop and seal:

[0039] After the metered oil injection is completed, the electric telescopic rod 9 drives the lifting rod and the injection plug 10 to reset, the pressure in the storage cylinder 6 disappears, and the rubber seal 12 in the oil outlet pipe re-closes due to its own elasticity to prevent lubricating oil from dripping and being wasted. If the lubrication cycle needs to be adjusted, the parameters can be reset through the timer 16.

[0040] Maintenance and adjustments:

[0041] If it is necessary to clean the oil filling hole 4 or replace parts, the first annular seat 3 can be rotated (using its outer wall anti-slip texture) to remove the first cylinder 5 and the annular frame 13 from the oil filling hole 4. The operation is convenient and does not damage the equipment.

[0042] The first annular seat 3 and the oil filling hole 4, as well as the storage cylinder 6 and the first annular seat 3, are all connected by threads. With the annular seat design featuring anti-slip texture, it is easy to quickly disassemble and assemble the storage cylinder 6 to replenish lubricating oil, or to disassemble the parts for cleaning and maintenance. The integrated structure of the storage cylinder 6, the second cylinder 7, and the oil outlet pipe 11 further enhances the stability of the overall assembly.

[0043] The first cylinder 5 is provided with an annular frame 13 below it. The outer ring of the annular frame 13 is provided with an annular groove 15. The bottom end of the first cylinder 5 is inserted into the annular groove 15 and is rotatably connected to the annular frame 13 through a bearing. The lower end of the annular frame 13 is provided with a rubber tube 14 that is inserted into the oil injection hole 4.

[0044] The rubber tube 14 at the lower end of the ring frame 13 is inserted into the oil injection hole 4, which can prevent lubricating oil from adhering to the inner wall of the oil injection hole 4 and keep the inner wall of the oil injection hole 4 clean.

[0045] Automated operation reduces reliance on manual inspections, lowers the risk of equipment failure due to human error, and reduces the workload of maintenance personnel. In the long run, it can significantly reduce equipment maintenance costs, ensure the stable operation of synchronous condensers, and indirectly improve the reliability of the power system.

[0046] The electric telescopic pole can be selected from model Z-Mod-EP-42ZS.

[0047] The pressure resistance of the rubber tube is sufficient to withstand the pressure generated when the injection plug pushes the lubricating oil in the storage cylinder, ensuring stable delivery of lubricating oil and preventing the rubber tube from rupturing due to excessive pressure.

[0048] The recommended timer is the ELKO EP CRM-100 model.
