Description

Technical Field

[0001] The present invention relates to the technical field of transmission devices, and more specifically, to a hydraulic crankshaft connecting rod transmission device. Background Art

[0002] Wave power generation refers to the technology of converting wave force into compressed air to drive air turbine generator to generate electricity through buoyancy pendulum wave power generation device. The pendulum is used to swing back and forth under the action of wave force to capture wave energy, and the kinetic energy and potential energy of the pendulum are converted into mechanical energy or hydraulic energy through the mechanical structure or hydraulic system connected to the pendulum, and then converted into electrical energy. The hydraulic crankshaft connecting rod transmission device is a transmission component for converting hydraulic energy into electrical energy, and its operating efficiency directly affects the efficiency of power generation. When the hydraulic crankshaft connecting rod transmission device uses the connecting rod as the active component, when the other two moving components are in the same straight line position, no matter how large the driving force is, the mechanism cannot be started, that is, there are two dead points.

[0003] At present, in order to enable the mechanism to pass the dead point smoothly and operate normally, two or more groups of mechanisms are usually used in combination, so that the dead points of each mechanism are arranged staggered with each other, and the crankshafts are driven by each other to avoid jamming, that is, the hydraulic system that pushes the connecting rod needs to be adjusted so that the time when each hydraulic system reaches the extreme point is staggered. However, the hydraulic system is driven by natural wave force, so it is difficult to achieve peak shifting.

[0004] There are also flywheels installed on the crankshaft on the market, which convert part of the mechanical energy into inertia. When at the dead point, the crankshaft and the connecting rod are driven past the dead point by inertia, and a driving part is installed on the crankshaft. When the starting point of the device is at the dead point, the driving part can drive it past the dead point and start smoothly. However, the flywheel is generally heavy. Maintaining the inertia of the flywheel and driving the additional driving part to rotate increases the consumption in the energy conversion process and reduces the efficiency of the final conversion into electrical energy. Moreover, the flywheel usually adopts an eccentric structure, which has a large friction on one side. Long-term operation can easily cause wear on one side and affect the overall use of the device. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a hydraulic crankshaft connecting rod transmission device which is anti-jamming and energy-efficient.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The hydraulic component and piston one are synchronously controlled by natural wave force. The hydraulic component is connected to a traction component, and a lever is connected to the traction component. The lever can push the connecting plate to rotate at the dead point position. When the piston drives the connecting plate to rotate, the hydraulic component runs synchronously, and the hydraulic component does not have a dead point position. When the transmission mechanism reaches the dead point position, the hydraulic component continues to run and pulls the lever to swing through the traction component. The lever pushes the connecting plate, so that the transmission mechanism breaks away from the dead point position and continues to run, thereby avoiding the device from getting stuck and improving the transmission energy efficiency.

[0011] The present invention is further configured as follows: the hydraulic component includes a hydraulic chamber 2, a hydraulic chamber 1 is arranged in the shell, the piston 1 is installed in the hydraulic chamber 1, a flow hole is connected between the hydraulic chamber 1 and the hydraulic chamber 2, a piston 2 is installed in the hydraulic chamber 2, the two ends of the piston 2 are respectively connected to the traction component, the piston 2 and the piston 1 are operated under the action of natural wave force, when the transmission mechanism reaches the dead point position, the piston 2 moves before the piston 1, thereby pulling the lever through the traction component to push the transmission mechanism to pass the dead point position, thereby avoiding the transmission mechanism from getting stuck.

[0012] It is further configured as follows: the traction assembly includes a left traction rope and a right traction rope, the left traction rope and the right traction rope are respectively connected to the two ends of piston 2, two steering wheel groups are installed on the outer shell, the left traction rope and the right traction rope are respectively wound around the corresponding steering wheel groups, the left traction rope and the right traction rope are parallel to the lever after winding, and the left traction rope and the right traction rope are respectively connected to the tail end of the lever from symmetrical positions on both sides.

[0014] The present invention is further configured as follows: a plurality of weight-reducing holes are evenly opened on the connecting plate, and reducing the weight of the connecting plate can reduce the mechanical energy converted into inertial force and improve the transmission energy efficiency.

[0015] The advantages of the present invention are:

[0016] 1. The power source of the auxiliary pushing mechanism is the hydraulic component. Both the hydraulic component and the transmission mechanism are driven by natural wave force. The hydraulic component has no dead point. When the transmission mechanism is stuck, the shift block on the connecting plate reaches the position of the shift rod, and the hydraulic component continues to move and drives the shift rod to rotate through the traction component. The push block on the shift rod pushes the corresponding shift block to move, thereby driving the connecting plate to pass the dead point position, preventing the transmission mechanism from getting stuck;

[0017] 2. The anti-jamming effect of inertia force is replaced by an auxiliary driving mechanism, and the connecting disc can be set as a homogeneous disc with small mass, so that the friction force at each point on the output shaft is relatively balanced, avoiding excessive wear and extending the service life of the device.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] See also Figure 1-10 , the present invention provides the following technical solutions:

[0031] A hydraulic crankshaft connecting rod transmission device changes the hydraulic piston from being able to only move vertically up and down, and adopts a crankshaft and a flywheel to change the hydraulic vertical up and down movement into a circular movement, comprising a housing 1, a transmission mechanism 2 is arranged in the housing 1, an active part of the transmission mechanism 2 is a connecting rod 22, a piston 21 is rotatably mounted on one end of the connecting rod 22, a connecting plate 23 is rotatably connected to the other end of the connecting rod 22, the connecting plate 23 is a homogeneous circular plate, an output shaft 24 is connected to the central axis of the connecting plate 23, an auxiliary pushing mechanism 3 is installed on the housing 1, the power source of the auxiliary pushing mechanism 3 is a hydraulic component 31, the hydraulic component 31 and the piston 21 are both driven by natural wave force, a traction component 32 is connected to the hydraulic component 31, a shifting rod 34 is connected to the traction component 32, and the shifting rod 34 can push the connecting plate 23 to rotate at the dead point position;

[0032] The connecting disk 23 is a homogeneous disk, and the friction force at each point on the output shaft 24 is relatively balanced, thereby avoiding unilateral friction and extending the service life of the device;

[0033] When the auxiliary driving mechanism 3 is used to replace the inertial force to drive the transmission mechanism 2 across the dead point, the connecting plate 23 can be made of a lighter material, which reduces the overall inertial force on the output shaft 24, reduces the damage of mechanical energy, and improves the transmission energy efficiency of the transmission device;

[0034] There is no dead point in the hydraulic component 31. When the transmission mechanism 2 reaches the dead point and gets stuck, the hydraulic component 31 continues to be driven by the natural wave force to move back and forth. At the same time, the traction component 32 pulls the lever 34 to swing back and forth. When the lever 34 swings, it pushes the connecting plate 23 to move, thereby driving the transmission mechanism 2 to cross the dead point. That is, this embodiment improves the transmission energy efficiency and reduces wear while avoiding the transmission device from getting stuck.

[0035] A plurality of weight-reducing holes 234 are evenly provided on the connecting plate 23, which reduces the weight of the connecting plate 23, thereby reducing the mechanical energy converted into inertial force and improving the transmission energy efficiency.

[0036] The connecting plate 23 includes a right plate 231 and a left plate 232, which are respectively located on both sides of the connecting rod 22. A shift block 233 is radially arranged on the annular side surface of the right plate 231 and the left plate 232. The shift block 233 is cylindrical and the two shift blocks 233 are symmetrically arranged.

[0037] The axes of the two shifting blocks 233 are perpendicular to the dead point line of the transmission mechanism 2, and the shifting rod 34 is spaced apart from the connecting plate 23 and parallel to the dead point line of the transmission mechanism 2, that is, when the transmission mechanism 2 moves to the dead point position, one of the two shifting blocks 233 faces the shifting rod 34, and the circular side surface of the corresponding shifting block 233 is perpendicular to the shifting rod 34;

[0038] A rotating shaft 13 is provided in the housing 1, and the center position of the lever 34 is rotatably installed on the rotating shaft 13. The lever 34 is in a "Y" shape, and the two tip ends of the lever 34 extend to the right disk 231 and the left disk 232 respectively. A push block 341 is provided on the side of the two tip ends of the lever 34 facing the right disk 231. The two push blocks 341 are strip-shaped, and the push blocks 341 can fit with the side walls of the lever blocks 233. The lever 34 is set on the side of the preset rotation direction of the connecting disk 23, and the push block 341 extends obliquely toward the direction of the connecting rod 22 away from the rotating shaft 13. The tail end of the lever 34 is connected to the traction assembly 32, and the traction assembly 32 can pull the lever 34 to swing around the rotating shaft 13.

[0039] The hydraulic assembly 31 includes a hydraulic chamber 2 311, a hydraulic chamber 1 11 is provided in the housing 1, a piston 1 21 is installed in the hydraulic chamber 11, a piston 2 312 is installed in the hydraulic chamber 2 311, and a through hole 14 is connected between the hydraulic chamber 1 11 and the hydraulic chamber 2 311, that is, the natural wave force can drive the piston 1 21 and the piston 2 312 at the same time;

[0040] One end of the second piston 312 facing the second hydraulic chamber 311 is connected to a piston rod 313, and the piston rod 313 extends out of the second hydraulic chamber 311. A packing seal 314 is provided on the hydraulic assembly 31, and the piston rod 313 is connected to the second hydraulic chamber 311 through the packing seal 314. The piston rod 313 is connected to the second hydraulic chamber 311 through a sliding seal. One end of the traction assembly 32 is connected to the end of the piston rod 313 extending out of the second hydraulic chamber 311. A dust cover 315 is sleeved on the end of the piston rod 313 extending out of the second hydraulic chamber 311, which can prevent leakage, ensure the hydraulic pressure in the second hydraulic chamber 311, and avoid excessive friction damage between the traction assembly 32 and the hydraulic assembly 31;

[0041] The traction assembly 32 includes a left traction rope 321 and a right traction rope 322. The left traction rope 321 is connected to one end of the piston 312 away from the hydraulic chamber 311. The right traction rope 322 is fixed to the piston rod 313. Two steering wheel groups 33 are installed on the housing 1. The left traction rope 321 and the right traction rope 322 are respectively wound around the corresponding steering wheel groups 33. After winding, the left traction rope 321 and the right traction rope 322 are parallel to the lever 34. The left traction rope 321 and the right traction rope 322 are respectively connected to the tail end of the lever 34 from symmetrical positions on both sides.

[0042] When the piston 2 312 moves, it drives the left traction rope 321 and the right traction rope 322 to move synchronously. After the left traction rope 321 and the right traction rope 322 pass through the corresponding steering wheel group 33 respectively, they pull the tail end of the lever 34 from the corresponding positions on both sides to move, so that the lever 34 swings back and forth around the rotating shaft 13.

[0043] With reference to the positional relationship in the accompanying drawings, the working principle of the present invention is as follows:

[0044] When the piston 1 21 moves to the bottom of the hydraulic chamber 1 11, the transmission mechanism 2 is at the dead point 1 position, the shift block 233 on the left plate 232 moves to below the shift rod 34, and the piston 2 312 is also located at the bottom of the hydraulic chamber 2 311. The right traction rope 322 pulls the tail end of the shift rod 34 from the right side, and the tip of the shift rod 34 is at the leftmost side.

[0045] After that, the hydraulic pressure in the hydraulic chamber 11 decreases, the transmission mechanism 2 does not move, and the hydraulic pressure in the hydraulic chamber 2 311 decreases faster, and the piston 2 312 moves upward, so that the left traction rope 321 pulls the tail end of the lever 34 from the left side, and the tip of the lever 34 rotates to the right, and the push block on the left side of the lever 34 pushes the push block 233 from the upper left, so that the connecting plate 23 rotates, and the transmission mechanism 2 passes the dead point position;

[0046] When the piston 1 21 moves to the top of the hydraulic chamber 1 11, symmetrical to the above process item, the piston 2 312 is located at the top of the hydraulic chamber 2 311, the left traction rope 321 drives the tip of the lever 34 to rotate to the rightmost side, and the lever block 233 on the right plate 232 moves to the bottom of the lever 34;

[0047] Afterwards, the liquid pressure in the hydraulic chamber 11 increases, the piston 2 312 moves downward, and the right traction rope 322 pulls the tip of the lever 34 to move to the left, thereby pushing the connecting plate 23 to rotate, and the transmission mechanism 2 passes the dead point position.

[0048] In summary, the power source of the auxiliary pushing mechanism 3 is the hydraulic assembly 31. The hydraulic assembly 31 and the transmission mechanism 2 are both driven by natural wave force. The hydraulic assembly 31 has no dead point. When the transmission mechanism 2 is stuck, the shifting block 233 on the connecting plate 23 reaches the position of the shifting rod 34, and the hydraulic assembly 31 continues to move, and drives the shifting rod 34 to rotate through the traction assembly 32. The push block 341 on the shifting rod 34 pushes the corresponding shifting block 233 to move, thereby driving the connecting plate 23 to pass the dead point position, preventing the transmission mechanism 2 from getting stuck.

[0049] The auxiliary propulsion mechanism 3 replaces the anti-jamming effect of the inertial force, and the connecting disk 23 can be set as a homogeneous disk with a small mass, so that the friction force at each point on the output shaft 24 is relatively balanced, avoiding excessive wear and extending the service life of the device. At the same time, the overall inertial force of the device is reduced, the damage of mechanical energy is reduced, and the transmission energy efficiency is improved.
