Description

Technical Field

[0001] The present invention relates to the technical field of speed reducer processing, in particular to a speed-variable control speed reducer for an interception net. Background Art

[0002] During the use of nuclear power plants, seawater needs to be cooled and filtered to ensure the purity of the water entering the nuclear power plant. Some debris may enter the nuclear power plant through ditches and affect the operation of the nuclear power plant. Therefore, in order to prevent these debris from entering the seawater and affecting the nuclear power plant, people have established a large number of interception nets and interception grids around the nuclear power seawater, and have established a marine life interception system including the deployment of pollution nets, cleaning and maintenance, and status monitoring in the surrounding sea areas. The practical application of this engineering system has achieved good results, effectively reducing the large-scale invasion of manatees, and also reducing the impact of garbage accumulation.

[0003] When the interception net is in the process of lifting, the motor is required to pull and control it, and the output end of the reducer needs to drag the interception net so that the interception net can bring out the intercepted debris and clean the interception net. The reducer must be used in this process. The reducer is in the process of transmitting power, but because the number of debris and marine life intercepted by the interception net is different each time, the resistance encountered by the reducer each time it is lifted is different. This causes the ordinary reducer to fail to take into account the quality of the interception net during the stretching process, causing the interception net to be damaged. At the same time, there is also the problem of excessive lifting speed, which causes the garbage intercepted by the interception net to break away from the interception net and be re-entered into the nuclear power seawater, affecting the stable operation of the nuclear power plant. Summary of the Invention

When the garbage and debris in the seawater are intercepted to a certain extent by the interception net, the motor responsible for lifting will drive the interception discharge When the gearbox comes out of the water, the reducer is needed to transfer kinetic energy. The input shaft is connected to the output end of the motor. When the input shaft rotates driven by the motor, the power will be transmitted to the speed gear set.

In the process of deceleration, the cooperation of the anti-backlash ratchet and the feedback tube can enable the reducer to obtain effective resistance feedback when rotating, and the number of feedback tubes can be adjusted according to the model of the reducer. At the same time, the kinetic energy transfer can be adjusted according to the resistance received, and the cooling pipe will ensure that the temperature inside the reducer will not be damaged by high temperature of the speed gear set due to excessive temperature.

[0007] The speed change gear set includes a transmission bevel gear and a large plate gear. The transmission bevel gear is meshed with the teeth on the input shaft. The transmission bevel gear and the large plate gear are respectively connected to the reducer housing for rotation. The transmission bevel gear is meshed with the large plate gear. Reduction bevel gears are respectively provided on both sides of the large plate gear. Each reduction bevel gear is respectively meshed with the large plate gear. The reduction bevel gear is rotatably connected to the reducer housing. A plurality of spherical gears are provided in the reducer housing, each spherical gear is respectively connected to the reducer housing for rotation, and each spherical gear is respectively meshed with the reduction bevel gear. The transmission gear will transmit the power from the input shaft, and the large plate gear will distribute the power. The large plate gear will drive the reduction bevel gear to rotate, and the reduction bevel gear will drive the spherical gear to rotate. The spherical gear will rotate with the rotation of the spherical gear, and the position of the spherical gear will be controlled by the feedback tube for regulation. When the position of the spherical gear changes, the transmitted speed will also change accordingly, thereby achieving the effect of stepless speed change.

[0008] The spherical gear includes a rotating ball and a transmission gear, the rotating ball is fixedly connected to the transmission gear, and the transmission gear is meshed with the output shaft through teeth, and a plurality of adaptive spring plates are provided on the rotating ball, and each adaptive spring plate is respectively provided with a plurality of adaptive teeth, and each adaptive tooth meshes with the bevel gear teeth on the reduction bevel gear. One end of the adaptive spring plate is fixedly connected to the rotating ball, and the adaptive spring plate is embedded in the rotating ball away from the rotating ball connection end and is slidably connected to the rotating ball. The transmission gear is connected to the feedback pipe, and a support spring is provided on the transmission gear, and the two ends of the support spring are respectively connected to the transmission gear and the reduction housing. When the transmission bevel gear rotates, the teeth on the adaptive spring plate on the rotating ball will mesh with the transmission bevel gear, thereby driving the rotating ball to rotate, and the adaptive spring plate on the rotating ball will realize meshing transmission with different numbers of teeth according to the tooth density on the transmission bevel gear, thereby achieving the effect of stepless speed change, and the rotation of the rotating ball will drive the transmission gear to rotate, and the rotation of the transmission gear drives the output shaft to rotate, and the support spring will always ensure that the rotating ball and the reduction bevel gear remain in meshing state.

[0009] The output shaft includes a mounting sleeve and an output bevel gear, the mounting sleeve is rotationally connected to the reducer housing, the mounting sleeve is provided with teeth, the teeth on the output bevel gear mesh with the teeth on the mounting sleeve, the output bevel gear is rotationally connected to the reducer housing, the output bevel gear is meshed with the transmission gear on the side away from the mounting sleeve, the output bevel gear is connected to the feedback tube, the mounting sleeve is connected to the shockproof assembly, the output bevel gear rotates under the action of the transmission gear, and drives the mounting sleeve to rotate, the mounting sleeve is connected to the interception net, so that the mounting sleeve can transmit power to the interception net, when the mounting sleeve rotates, the anti-backward ratchet will rotate and cooperate with the feedback tube to adjust the position of the output bevel gear.

[0010] The feedback tube includes a detection pipe, an anti-rebound sheet is provided in the detection pipe, the anti-rebound sheet is fixedly connected to the detection pipe, a transmission piston is provided in the detection pipe, the transmission piston is against the anti-rebound sheet, the transmission piston is in sliding contact with the detection pipe, a release piston is provided on the side of the detection pipe away from the transmission piston, an adjustment connecting rod is provided on the release piston, the adjustment connecting rod is rotationally connected to the reducer housing, and the end of the adjustment connecting rod away from the release piston is connected to the output bevel gear. When the anti-rebound ratchet is working, the anti-rebound ratchet will transmit the resistance on the mounting sleeve and transmit this resistance to the anti-rebound sheet, and the anti-rebound sheet will mobilize the transmission piston to move. The transmission piston moves in the detection pipe and, through pressure transmission, causes the release piston to move. The release piston will drive the adjustment connecting rod to move, and the adjustment connecting rod will cause the position of the output bevel gear to change.

The feedback gear is connected to the reducer housing in rotation, and the feedback gear is meshed with the adjusting link. The reducer housing is provided with a feedback link, and the output bevel gear passes through the feedback link and is connected to the feedback link in rotation. The feedback link is slidably connected to the reducer housing, and the feedback gear is meshed with the feedback link. When the adjusting link moves, it will drive the feedback gear to rotate, and the rotation of the feedback gear will cause the feedback link to move. After the feedback link moves, the position of the output bevel gear will change, thereby changing the position of the spherical gear, thereby achieving a speed change effect. When the pressure received by the feedback shrapnel increases, the teeth of the spherical gear will reduce the meshing of the teeth on the reducer bevel gear, thereby reducing the rotation speed of the spherical gear, thereby making the rotation of the mounting sleeve smoother and more efficient in removing debris.

[0012] The anti-vibration component includes a lubricated bearing, which is sleeved on the mounting sleeve. The lubricated bearing is arranged on the reducer housing. A plurality of shock-absorbing springs are arranged on the inner ring of the lubricated bearing. The shock-absorbing springs are arranged in an oil-passing turbine. The oil-passing turbine is rotatably connected to the reducer housing. A plurality of expansion sliders are arranged in the oil-passing turbine. Each expansion slider is provided with a thread near the side of the oil-passing turbine. The two ends of the shock-absorbing spring respectively press against the expansion slider and the inner ring of the lubricated bearing. The expansion slider is engaged with the thread on the oil-passing turbine. When the mounting sleeve rotates, the inner ring of the lubricated bearing will rotate accordingly. When the mounting sleeve vibrates, the inner ring of the lubricated bearing will also vibrate, and drive the shock-absorbing spring to vibrate, so that the shock-absorbing spring transmits power to the expansion slider. After the expansion slider expands outward, it will drive the oil-passing turbine to rotate. The rotation of the oil-passing turbine will cause the lubricating oil to flow, and the stiffness of the cooling shock-absorbing spring will increase. At the same time, the operation of the lubricated bearing will be more stable, and at the same time, the debris on the lubricated bearing will be better removed, avoiding the problem of vibration of the mounting sleeve due to oil pollution.

[0013] A lubrication pipe is provided in the reducer housing near the large plate gear, and an oil residue filter is provided in the lubrication pipe. A filter mounting bracket is provided in the lubrication pipe, and the oil residue filter is provided on the filter mounting bracket in the lubrication pipe. The filter mounting bracket is rotatably connected to the lubrication pipe, and the filter mounting bracket is provided with rotating fan blades. When the oil-passing turbine rotates, the lubricating oil in the reducer will flow, and these lubricating oils will be mixed with lubricating oils that can no longer be used. These lubricating oils are usually very viscous and accompanied by a large amount of solid sediments, so they pose a certain threat to other parts. Therefore, the oil residue filter will play a very important role. At the same time, the filter mounting bracket will rotate with the flow of the lubricating oil, which can make the oil residue filter filter out waste residue more evenly and reduce blockage.

[0014] The pressurized anti-blocking chamber includes a pressurized chamber, a repeated airbag is provided in the pressurized chamber, the repeated airbag is communicated with the interior of the reducer housing, a surging shrapnel is provided in the pressurized chamber, the surging shrapnel and the pressurized chamber are rotatably connected through a spring shaft, the surging shrapnel is away from the spring shaft. One end of the surging shrapnel is embedded in the reducer housing and in sliding contact with the reducer housing, a pressurized ball is provided on the surging shrapnel, the pressurized ball is hinged to the surging shrapnel, the repeated airbag is away from the reducer housing. One end of the cavity pressurized ball presses against the surging shrapnel. When transmitting power, the repeated airbag in the pressurized chamber will feel the temperature inside the reducer housing. It expands or contracts with the change of temperature. The expansion process will drive the surging shrapnel to move, and the surging shrapnel will drive the pressurized ball to move, so that the flow speed of the cooling medium in the pressurized chamber is accelerated. The cooling medium in the cooling pipe flows under the action of the cooling pump. The surging shrapnel increases the flow direction and circulation volume of the cooling medium, and the surging shrapnel will affect the flow speed of the debris in the cooling pipe to avoid deposition and retention, thereby avoiding the blockage of the cooling pipe in the reducer and reducing the cooling efficiency.

[0015] The working principle of the present invention is: when the interception net needs to be lifted and raised, the motor responsible for lifting will drive the interception net to be discharged from the water surface. At this time, the reducer is needed to transmit kinetic energy, and the input shaft is connected to the output end of the motor. When the input shaft rotates under the drive of the motor, the power will reach the large plate gear through the transmission bevel gear. The large plate gear will also drive the reduction bevel gear to rotate while distributing the power, and through the cooperation of the reduction bevel gear and the spherical gear, the reducer can achieve the effect of stepless speed change. At the same time, when the power is transmitted, the shock-absorbing spring will collect the vibration from the lubricated bearing and convert it into the power of the lubricating oil flow, which can fully Reduce the vibration of the output shaft, and the anti-backlash ratchet will rotate with the rotation of the output shaft. During the deceleration process, the cooperation between the anti-backlash ratchet and the feedback tube can enable the reducer to obtain effective resistance feedback during rotation. Adjusting the relative movement between the connecting rod and the feedback connecting rod will change the position of the spherical gear, and thus the transmitted power will also change. The cooling pipe will ensure that the temperature inside the reducer is maintained within a stable range, so that the speed change gear set will not suffer from high-temperature damage. In the internal cooling pipe, the filter mounting bracket will ensure that the oil residue filter is cleaned in time to avoid blockage and maintain stable operation of the equipment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts a feedback-type deceleration component, which adjusts the position of the speed gear set through the pressure received on the output shaft, and utilizes the cooperation between the spherical gear and the speed gear set to achieve the effect of stepless speed change, thereby indirectly enabling the reducer to achieve multi-stage speed change rather than a single transmission deceleration, and through timely feedback, more precise speed change can be achieved, thereby protecting the interception net.

[0017] 2. The present invention adopts a structural coordination between the lubricating bearing and the shockproof component, which can enable the shockproof component to obtain timely feedback during operation. Such structural coordination can make the present invention more stable during operation. The shockproof component can not only stabilize the output shaft in time, but also mobilize the lubricating oil to flow, so that the present invention can be adequately lubricated during operation.

[0018] 3. The present invention adopts an anti-blocking cooling structure and an anti-deposition lubrication structure, so that the present invention can fully guarantee the speed change efficiency of the speed change gear set during operation. At the same time, sufficient lubrication conditions and stable temperature changes can greatly extend the service life of the speed change gear set. BRIEF DESCRIPTION OF THE DRAWINGS

A pressurized ball 1104 is provided on the surging shrapnel 1103, and the pressurized ball 1104 is hinged to the surging shrapnel 1103, and the repeated airbag 1102 is away from one end of the chamber of the reducer housing 2 against the surging shrapnel 1103. When transmitting power, the reverse airbag 1102 in the pressurized chamber 1101 The complex air bag 1102 will sense the temperature inside the reducer housing 2 and expand or contract as the temperature changes. During the expansion process, the surging spring 1103 will be driven to move, and the surging spring 1103 will drive the pressurizing ball 1104 to move, so that the flow speed of the cooling medium in the pressurizing chamber 1101 is accelerated, and the cooling medium in the cooling pipe 10 flows under the action of the cooling pump. The action of the surging spring 1103 increases the flow direction and circulation volume of the cooling medium, and the surging spring 1103 will affect the flow speed of the debris in the cooling pipe 10 to avoid deposition and retention, thereby avoiding the blockage of the cooling pipe 10 in the reducer and reducing the cooling efficiency.

[0040] The working principle of the present invention is: when the interception net needs to be lifted and raised, the motor responsible for lifting will drive the interception net to be discharged from the water surface. At this time, the reducer is needed to transmit kinetic energy, and the input shaft 4 is connected to the output end of the motor. When the input shaft 4 rotates under the drive of the motor, the power will reach the large disk gear 502 through the transmission bevel gear 501. The large disk gear 502 will drive the reduction bevel gear 503 to rotate while distributing the power, and through the cooperation of the reduction bevel gear 503 and the spherical gear 12, the reducer can achieve the effect of stepless speed change. At the same time, when power is transmitted, the shock-absorbing spring 702 will collect the vibration from the lubricating bearing 701 and convert it into the power of lubricating oil flow, which can fully reduce the speed. Reduce the vibration of the output shaft 6, and the anti-backlash ratchet 8 will rotate with the rotation of the output shaft 6. During the deceleration process, the cooperation between the anti-backlash ratchet 8 and the feedback tube 9 can enable the reducer to obtain effective resistance feedback during rotation. The relative movement between the adjusting connecting rod 905 and the feedback connecting rod 907 will change the position of the spherical gear 12, and thus the transmitted power will also change. The cooling pipe 10 will ensure that the temperature inside the reducer is maintained within a stable range, so that the speed change gear set 5 will not be damaged by high temperature. In the internal cooling pipe 10, the filter mounting frame 1302 will ensure that the oil residue filter 1301 is cleaned in time to avoid blockage and maintain stable operation of the equipment.
