Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bulb tubular turbine unit, more specifically, a bulb tubular turbine unit control ring oiling device. BACKGROUND

[0002] Bulb tubular turbine generator units are more in production in recent years, and are an important branch of hydropower, the water guide mechanism is one of important components of the water turbine, the control ring is connected to the force amplifier to control the guide vane switch, plays the role of guiding the water flow to form a circular flow and controlling the flow, and the unit control ring is the core equipment for controlling the guide vane to adjust the water volume. Since the traditional mature double-V-shaped groove + steel ball structure mode, wear will occur in the running process, the wear will gradually increase with time, and the lubrication is poor, which leads to the control ring jamming and even causes the guide vane to be unable to close, resulting in the hidden danger of accidents. The research on the control ring structure, wear reason and other factors seeks to reduce and reduce the wear method, increase the service life of the control ring, and has a positive effect on improving the economic and safe operation of the unit.

[0003] At present, most of the bulb tubular turbine unit hydropower stations at home and abroad adopt the method of adding lubricating grease once a year during maintenance, and most of them use manual grease guns, which is low in efficiency and small in amount of lubricating grease. In view of this, we provide a bulb tubular turbine unit control ring oiling device. UTILITY MODEL CONTENTS

[0004] The utility model aims at overcoming the defects of the prior art, adapting to the actual needs, and providing a bulb tubular turbine unit control ring oiling device to solve the technical problems of low efficiency and small amount of lubricating grease in the current bulb tubular turbine unit control ring.

[0005] To solve the above technical problems, the utility model provides the following technical scheme: a bulb tubular turbine unit control ring oiling device, which comprises a base, a force amplifier, a push-pull rod, an outer water distribution ring and a control ring main body, the control ring main body is arranged on the outer water distribution ring, the force amplifier is symmetrically arranged on the top of the base on both sides, one end of the push-pull rod is rotatably connected with the piston end of the force amplifier, the other end of the push-pull rod is movably connected with the control ring main body, a storage box is arranged on the top of the base, an oil pump is arranged on one side of the storage box on the top of the base, the input end of the oil pump is connected with the output end of the storage box through a hose, a flow guide ring is sleeved on the front side of the control ring main body on the outer water distribution ring, the input end of the flow guide ring is connected with the output end of the oil pump through a hose, and a plurality of groups of connecting pipes are equidistantly arranged on one side of the flow guide ring facing the control ring main body.

[0006] The connecting pipe is internally provided with a blockage structure.

[0007] This invention, through the design of a storage tank, oil pump, guide ring, and connecting pipe, allows for the connection and fixing of the connecting pipe on the guide ring to the oil inlet on the control ring body during operation of the control ring main body in conjunction with the bulb-type flow unit. The oil pump's operating time interval is set via an external controller, and after each interval, the oil pump automatically delivers lubricating oil from the storage tank to the guide ring. The lubricating oil is then delivered from the oil inlet to the control ring body via the connecting pipe, thus achieving automatic lubrication of the control ring body. This lubrication method offers advantages such as high pressure, high efficiency, large grease dosage, and real-time operation, solving the safety risks and manpower requirements of high-altitude lubrication and providing higher lubrication assurance. The connecting pipe of this invention incorporates a blocking structure, with both the blocking ring and the blocking seat... The components are frustum-shaped and matched, with the larger end of the blocking ring and the smaller end facing forward. Therefore, during oil injection, as the pressure in the connecting pipe gradually increases, the blocking seat will separate from the blocking ring, allowing for normal oil injection. After oil injection, the blocking seat will reset under the assistance of the spring and re-insert into the blocking ring, achieving the blocking effect. Furthermore, the lubricating oil inside the control ring body ensures better pressure when the blocking seat is inserted into the blocking ring, thus enhancing the blocking effect. This effectively isolates the lubricating oil inside the control ring body from the lubricating oil in the guide ring, preventing mixing and contamination of the lubricating oil in the guide ring. This ensures the quality of the subsequent self-lubricating oil, guaranteeing the self-lubricating effect on the control ring body.

[0008] Preferably, the front side of the control ring body is provided with symmetrical oil inlets for the connecting pipe, and the oil inlets are connected to the connecting pipe.

[0009] Preferably, the blocking structure includes a blocking ring, a blocking seat, a mounting bracket, and a spring. The blocking ring is arranged inside the connecting pipe, the blocking seat is arranged inside the blocking ring, the mounting bracket is arranged inside the connecting pipe, and the spring is arranged between the mounting bracket and the blocking seat. The mounting bracket includes a disc, and several sets of connecting blocks are equidistantly arranged around the disc, and the connecting blocks are connected to the inner wall of the connecting pipe.

[0010] Preferably, a limiting hole is provided in the center of the disc, and a limiting rod is arranged in the center of the side of the blocking seat facing the mounting frame, and the limiting rod passes through the limiting hole.

[0011] Preferably, the inner wall of the limiting hole is provided with several sets of limiting grooves at equal intervals, and the limiting rod is provided with limiting strips symmetrical to the limiting grooves, and the limiting strips penetrate the limiting grooves.

[0012] Preferably, the connecting block has a connecting rod arranged on the side facing the blocking seat, and a top plate is arranged on the end of the connecting rod facing away from the connecting block.

[0013] Preferably, both the inner hole of the blocking ring and the blocking seat are frustum-shaped, and the size of the inner hole of the blocking ring matches the size of the blocking seat, with the larger end of the inner hole of the blocking ring and the smaller end of the blocking seat facing backward and forward.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through its designed storage tank, oil pump, guide ring, and connecting pipe, allows for the connection and fixing of the connecting pipe on the guide ring to the oil inlet on the control ring body during the operation of the control ring main body in conjunction with the bulb-type turbine unit. The oil pump's operating time interval is set via an external controller, and after each interval, the oil pump automatically delivers lubricating oil from the storage tank to the guide ring. The lubricating oil is then delivered from the oil inlet to the control ring body via the connecting pipe, thus achieving automatic lubrication of the control ring body. This lubrication method offers advantages such as high pressure, high efficiency, large grease dosage, and real-time operation. It solves the safety risks and manpower requirements of high-altitude grease application, providing higher lubrication assurance. It also addresses the technical problems of low efficiency and insufficient grease dosage associated with manual lubrication of the control ring in current bulb-type turbine units. Therefore, this utility model possesses the advantage of autonomous lubrication.

[0016] 2. The connecting pipe of this utility model is equipped with a blocking structure. Both the blocking ring and the blocking seat in the blocking structure are frustum-shaped and matched. The larger end of the blocking ring and the blocking seat face backward and the smaller end faces forward. Therefore, during oil injection, as the pressure in the connecting pipe gradually increases, the blocking seat will separate from the blocking ring, allowing normal oil injection to proceed. After oil injection, the blocking seat will reset under the cooperation of the spring and re-insert into the blocking ring, achieving the blocking effect. Furthermore, the lubricating oil inside the control ring body can better ensure the pressure of the blocking seat inserted into the blocking ring, thus achieving a better blocking effect. This can isolate the lubricating oil inside the control ring body from the lubricating oil in the guide ring, preventing the lubricating oil inside the control ring body from mixing with the lubricating oil in the guide ring and thus contaminating the lubricating oil in the guide ring. This ensures the quality of the lubricating oil for subsequent self-lubrication, thereby ensuring the effectiveness of self-lubrication of the control ring body. Attached Figure Description

[0026] like Figures 1 to 7 As shown, this utility model relates to a bulb-type turbine control ring refueling device, including a base 1, a relay 2, a push-pull rod 3, an external water distribution ring 4, and a control ring body 5. The control ring body 5 is arranged on the external water distribution ring 4. The relay 2 is symmetrically arranged on both sides of the top of the base 1. One end of the push-pull rod 3 is rotatably connected to the piston end of the relay 2, and the other end of the push-pull rod 3 is movably connected to the control ring body 5. A storage tank 6 is arranged on the top of the base 1, and an oil pump 7 is arranged on one side of the storage tank 6 on the top of the base 1. The input end of the oil pump 7 is connected to the output end of the storage tank 6 through a hose. A guide ring 8 is sleeved on the external water distribution ring 4 on the front side of the control ring body 5. The input end of the guide ring 8 is connected to the output end of the oil pump 7 through a hose. Several sets of connecting pipes 9 are equidistantly arranged on the side of the guide ring 8 facing the control ring body 5. A symmetrical oil filling port 501 of the connecting pipe 9 is arranged on the front side of the control ring body 5, and the oil filling port 501 is connected to the connecting pipe 9.

[0027] Therefore, during the operation of the control ring body 5 in conjunction with the bulb-type cyclone generator, the connecting pipe 9 on the guide ring 8 can be connected and fixed to the oil inlet 501 on the control ring body 5. Then, the working time interval of the oil pump 7 is set by the external controller. After each time interval, the oil pump 7 automatically controls the oil pump 7 to deliver the lubricating oil in the storage tank 6 to the guide ring 8. Then, the lubricating oil is delivered from the oil inlet 501 to the inside of the control ring body 5 through the connecting pipe 9. This achieves automatic oiling of the control ring body 5. This oiling method has the advantages of high pressure, high efficiency, large grease dosage, and real-time operation, which solves the safety risks and manpower input of greaseing at high altitudes and provides higher assurance for lubrication.

[0028] In an embodiment of this utility model, a blocking structure 10 is arranged inside the connecting pipe 9; the blocking structure 10 includes a blocking ring 11, a blocking seat 12, a mounting bracket 13, and a spring 14. The blocking ring 11 is arranged inside the connecting pipe 9, the blocking seat 12 is arranged inside the blocking ring 11, the mounting bracket 13 is arranged inside the connecting pipe 9, and the spring 14 is arranged between the mounting bracket 13 and the blocking seat 12. The mounting bracket 13 includes a disk 1301, and a plurality of connecting blocks 1302 are equidistantly arranged around the disk 1301, and the connecting blocks 1302 are connected to the inner wall of the connecting pipe 9; the inner hole of the blocking ring 11 and the blocking seat 12 are both frustum-shaped, and the size of the inner hole of the blocking ring 11 matches the size of the blocking seat 12, with the larger end of the inner hole of the blocking ring 11 and the smaller end of the blocking seat 12 facing backward and forward.

[0029] During oil injection, as the pressure inside the connecting pipe 9 gradually increases, the blocking seat 12 will separate from the blocking ring 11, allowing normal oil injection to proceed. After oil injection, the blocking seat 12 will reset under the cooperation of the spring 14 and re-insert into the blocking ring 11, achieving the blocking effect. Furthermore, the lubricating oil inside the control ring body 5 helps to better ensure the pressure of the blocking seat 12 inserted into the blocking ring 11, thus achieving a better blocking effect. This isolates the lubricating oil inside the control ring body 5 from the lubricating oil in the guide ring 8, preventing them from mixing and contaminating the lubricating oil in the guide ring 8. This ensures the quality of the lubricating oil used for subsequent self-lubrication, thus guaranteeing the self-lubrication effect of the control ring body 5.

[0030] Specifically, a limiting hole 1303 is provided in the center of the disc 1301, and a limiting rod 1201 is arranged in the center of the side of the blocking seat 12 facing the mounting bracket 13, and the limiting rod 1201 passes through the limiting hole 1303; the limiting hole 1303 and the limiting rod 1201 can limit the movement of the blocking seat 12, ensuring that the blocking seat 12 can move back and forth stably and avoid deviation.

[0031] Furthermore, the inner wall of the limiting hole 1303 is provided with several sets of limiting grooves 1304 at equal intervals, and the limiting rod 1201 is provided with limiting strips 1202 symmetrical to the limiting grooves 1304 around its circumference, and the limiting strips 1202 penetrate through the limiting grooves 1304; the limiting grooves 1304 and the limiting strips 1202 can limit the blocking seat 12 and prevent the blocking seat 12 from rotating.

[0032] Furthermore, a connecting rod 1305 is arranged on the side of the connecting block 1302 facing the blocking seat 12, and a top plate 1306 is arranged on the end of the connecting rod 1305 facing away from the connecting block 1302; the connecting rod 1305 and the top plate 1306 are used to limit the movement of the blocking seat 12 to prevent the blocking seat 12 from leaving the blocking ring 11 by too much distance.

[0033] Working Principle: This embodiment provides a lubrication device for the control ring of a bulb-type turbine generator set. First, during the operation of the control ring body 5 in conjunction with the bulb-type turbine generator set, the connecting pipe 9 on the guide ring 8 can be connected and fixed to the oil inlet 501 on the control ring body 5. Then, the working time interval of the oil pump 7 is set by an external controller. After each time interval, the oil pump 7 automatically controls the oil pump 7 to deliver the lubricating oil in the storage tank 6 to the guide ring 8. Then, the lubricating oil is delivered from the oil inlet 501 to the inside of the control ring body 5 through the connecting pipe 9, thereby realizing automatic lubrication of the control ring body 5. This lubrication method has the advantages of high pressure, high efficiency, large lubricating grease dosage, and real-time operation, solving the safety risks and manpower input of high-altitude operation grease filling, and providing higher guarantee for lubrication.

[0034] Secondly, during oil injection, as the pressure inside the connecting pipe 9 gradually increases, the blocking seat 12 will separate from the blocking ring 11, allowing normal oil injection to proceed. After oil injection, the blocking seat 12 will reset under the cooperation of the spring 14, and the blocking seat 12 will re-insert into the blocking ring 11, achieving the blocking effect. Furthermore, the lubricating oil inside the control ring body 5 can better ensure the pressure of the blocking seat 12 inserted into the blocking ring 11, thus achieving a better blocking effect. This can isolate the lubricating oil inside the control ring body 5 from the lubricating oil in the guide ring 8, preventing the lubricating oil inside the control ring body 5 from mixing with the lubricating oil in the guide ring 8, thereby contaminating the lubricating oil in the guide ring 8 and ensuring the quality of the lubricating oil for subsequent self-lubrication, thus ensuring the self-lubrication effect of the control ring body 5.
