Description

Technical Field

[0001] The present invention relates to the technical field of pumping units, and particularly to a new type of energy-saving pumping unit. Background Art

[0002] A pumping unit is a machine device for oil extraction, commonly known as a "nodding donkey". A pumping unit is the main lifting equipment in a rod pumping system. According to whether there is a walking beam, it can be divided into a beam pumping unit and a beamless pumping unit. The working principle of a beam pumping unit is as follows: power is supplied by a prime mover, and the high-speed rotation of the prime mover is changed into the low-speed rotation of the crank of the pumping unit through a speed reducer. The crank-link-walking beam mechanism changes the rotational motion into the up-and-down reciprocating motion of the pony head of the pumping unit, and drives a deep well pump to work through a suspension rope assembly. The main components of a beam pumping unit include: a prime mover that provides power; a speed reducer that transmits power and reduces speed; a four-bar mechanism (crank, connecting rod, walking beam, support, cross beam, and base) that transmits power and changes the rotational motion into a reciprocating motion; a pony head and a suspension rope assembly that transmit power and ensure that the polished rod makes a reciprocating linear motion; a braking device that enables the pumping unit to stay at any position; and a balancing device that enables the prime mover to work within a relatively small load change range, etc.

[0003] After retrieval, a new type of energy-saving pumping unit and application method disclosed in the application number 201410679732.8 is an oil well pumping technology in the oilfield. It overcomes the disadvantages of current pumping units. Its structural relationship is that one end of the front walking beam is connected to the pony head, and the other end of the front walking beam is connected to the upper end of the rear walking beam through a rear walking beam bearing. The lower end of the rear walking beam is connected to one end of the bottom beam through a bottom beam rear bearing; the other end of the bottom beam is connected to the support through a bottom beam front bearing. Thus, a parallelogram is formed among the four points of the middle bearing, the rear walking beam bearing, and the two bearings of the bottom beam. The other end of the rear walking beam is connected to the connecting rod, and the other end of the connecting rod is connected to the crank; there is a speed reducer between the crank and the motor; there is a counterweight at the rear end of the rear walking beam; the middle bearing is fixed at the top of the support and is located at the lower end of the front walking beam. Among them, when the pony head makes a downward free fall, the kinetic energy generated by the free fall cannot be recovered and stored, resulting in waste of kinetic energy. Although the adjustment of the counterweight block is relatively cumbersome and cannot be automatically adjusted following the movement of the walking beam.

[0004] After retrieval, a variable force arm type self-balancing new type of energy-saving pumping unit disclosed in the application number 202111502899.3 includes a sucker rod, a pony head, a clutch, a walking beam frame, a walking beam, a force arm adjustment device, a counterweight rope, a counterweight frame, and a counterweight box. The pony head at one end of the walking beam pulls the sucker rod to move up and down. The torque of the walking beam structure among them cannot be adjusted. When the walking beam makes a lever motion, the motor needs to overcome the resistance of the part exceeding the dynamic imbalance during the operation of the pumping unit, which leads to the motor running overload, and even causes greater impacts on various transmission components of the pumping unit, resulting in damage to the speed reducer, transmission shaft, bearings, etc.

[0005] After retrieval, application number 201811499852.4 discloses a variable-force-arm self-balancing new energy-saving pumping unit, which includes a sucker rod, a walking beam head, a clutch, a walking beam frame, a walking beam, a force arm adjusting device, a counterweight rope, a counterweight frame and a counterweight box. The walking beam head at one end of the walking beam pulls the sucker rod to move up and down. A clutch is provided between the walking beam and the walking beam frame. A force arm adjusting device is provided at the other end of the walking beam and is connected to the counterweight box through a counterweight rope. This machine changes the size of the walking beam force arm by the reciprocating movement of the moving platform assembly of the force arm adjusting device, thereby adjusting the walking beam moment. When the walking beam moment on the walking beam head side is less than the walking beam moment on the counterweight box side, the walking beam head moves upward, and vice versa. The movement of the counterweight box is controlled by proximity switches and limit switches on the counterweight frame, thereby realizing the pumping action. This machine simplifies the force arm adjustment method and counterweight method of the traditional balanced walking beam pumping unit, reduces the power of the driving motor, and has the characteristics of automatic force arm adjustment, convenient counterweight adjustment, energy saving and high efficiency.

[0006] In the above technical solution, the force arm adjusting device is controlled by a motor to operate. During the operation process, its driving force causes energy loss. When the pumping unit is operating, it not only needs to recover energy for storage, but also needs to save the consumed energy, so as to reduce the overall energy consumption and solve the problem of large energy consumption of the pumping unit.

[0007] Therefore, we propose a new energy-saving pumping unit. Summary of the Invention

A power generator is arranged inside the first energy storage device. The power generator converts the power into electric energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjusting box. The power generated by the magnetic balls rolling back and forth in the arm adjusting box is also converted into electric energy through the second energy storage device and stored in the second energy storage device. Beneficial effects

[0021] The present invention provides a new type of energy-saving pumping unit, having the following beneficial effects: (1) The new type of energy-saving pumping unit drives the walking beam on the support frame to perform a lever motion through a driving mechanism. When the walking beam continuously performs the lever motion, it drives the linkage rod and the splicing rod to slide up and down to generate power. A power generator is arranged inside the first energy storage device, and the power generator converts the power into electrical energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjustment box. The power generated by the magnetic rolling ball rolling back and forth inside the arm adjustment box is also converted into electrical energy through the second energy storage device and stored in the second energy storage device. By recovering and converting the kinetic energy generated during the operation of the pumping unit, the kinetic energy is converted into electrical energy and collected, achieving the effect of automatically collecting energy, reducing energy consumption, and achieving the effect of recovering kinetic energy.

[0022] (2) The new type of energy-saving pumping unit drives the walking beam on the support frame to perform a lever motion through a driving mechanism. When the walking beam continuously performs the lever motion, it drives the linkage rod and the splicing rod to slide up and down to generate power. A power generator is arranged inside the first energy storage device, and the power generator converts the power into electrical energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjustment box. The power generated by the magnetic rolling ball rolling back and forth inside the arm adjustment box is also converted into electrical energy through the second energy storage device and stored in the second energy storage device. By recovering and converting the kinetic energy generated during the operation of the pumping unit, the driving motor inside the driving equipment box drives the central shaft to rotate freely, so that the central shaft drives the wire wheel to rotate synchronously, facilitating the wire wheel to wind or release the connecting cable. When the wire wheel rotates, the wire wheel drives the extrusion column to move along the annular groove as a path. When the extrusion column rotates to a position close to the convex block, the extrusion column is driven by the extrusion force of the convex block to drive the wire wheel to slide along the central axis to the side away from the fixed disk. A return spring is movably sleeved on the outer circle of the central shaft. When the extrusion column rotates away from the convex block, the wire wheel slides reversely along the central axis under the elastic force of the return spring. Through the cooperation of the set annular groove and the convex block, the wire wheel can slide back and forth along the central axis during the rotation process. By controlling the back-and-forth sliding of the wire wheel, it is convenient to evenly wind the connecting cable, achieving the effect of evenly winding the connecting cable.

[0023] (3) The novel energy-saving pumping unit drives the walking beam on the support frame to perform a lever motion through the drive mechanism. When the walking beam continuously performs the lever motion, it drives the linkage rod and the splicing rod to slide up and down to generate power. A power generator is arranged inside the first energy storage device. The power generator converts the power into electrical energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjustment box. The power generated by the magnetic balls rolling back and forth inside the arm adjustment box is also converted into electrical energy through the second energy storage device and stored in the second energy storage device. When the pumping unit is operating, the central shaft drives the driving gear to rotate together during the rotation process. When the gear surface of the driving gear rotates close to the driven gear, it will drive the driven gear to rotate together. When the smooth surface of the driving gear rotates close to the driven gear, the driven gear rotates reversely and resets under the action of the reset rotating shaft. When the wire wheel drives the driving gear to rotate clockwise, the connecting cable is released from the wire wheel. At this time, the driving gear drives the driven gear to rotate counterclockwise, and the driven gear drives the L-shaped long rod to turn upward. The L-shaped long rod drives the magnetic plate to be vertically upward and distributed at the rear side of the arm adjustment box. The magnetic force generated by the magnetic plate repels the magnetic balls. At this time, the magnetic balls roll forward to the front side inside the arm adjustment box under the repulsive force. When the magnetic balls roll to the front side inside the arm adjustment box, the donkey head moves downward under its own gravity. By setting the rolling magnetic balls, the effect of conveniently adjusting the moment of the walking beam is achieved, and the energy loss is reduced.

[0024] (4) The novel energy-saving pumping unit drives the walking beam on the support frame to perform a lever motion through the drive mechanism.

A power generator is arranged inside the first energy storage device. The power generator converts the power into electrical energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjustment box.

When the pumping unit is operating, the central shaft drives the driving gear to rotate together during the rotation process. When the gear surface of the driving gear rotates close to the driven gear, it will drive the driven gear to rotate together. When the smooth surface of the driving gear rotates close to the driven gear, the driven gear rotates reversely and resets under the action of the reset rotating shaft. When the wire wheel drives the driving gear to rotate clockwise, the connecting cable is released from the wire wheel. At this time, the driving gear drives the driven gear to rotate counterclockwise, and the driven gear drives the L-shaped long rod to turn upward. The L-shaped long rod drives the magnetic plate to be vertically upward and distributed at the rear side of the arm adjustment box. The magnetic force generated by the magnetic plate repels the magnetic balls. At this time, the magnetic balls roll forward to the front side inside the arm adjustment box under the repulsive force. By driving the driven gear to move through the driving gear, the position of the magnetic plate is changed to repel the magnetic balls, avoiding using external energy to drive the magnetic balls to move, and the effect of saving energy is achieved.

[0025] (5) The novel energy-saving pumping unit drives the walking beam on the support frame to perform a lever motion through a driving mechanism. When the walking beam continuously performs the lever motion, it drives the linkage rod and the splicing rod to slide up and down to generate power. A power generator is arranged inside the first energy storage device. The power generator converts the power into electric energy and stores it inside the first energy storage device. A second energy storage device is arranged on the front side inside the arm adjustment box.

The power generated by the magnetic rolling ball 30 rolling back and forth inside the arm adjustment box 7 is also converted into electrical energy through the second energy storage device 41 and stored in the second energy storage device 41. By recovering and converting the kinetic energy generated by the pumping unit during operation, when the pumping unit is running, the driving motor inside the driving equipment box 17 drives the central shaft 23 to rotate freely, so that the central shaft 23 drives the wire wheel 15 to rotate synchronously, facilitating the wire wheel 15 to wind or release the connecting cable 16. When the wire wheel 15 rotates, the wire wheel 15 drives the extrusion column 27 to move along the annular groove 25 as a path.

When the pumping unit is running, the central shaft 23 drives the driving gear 18 to rotate together during the rotation process. When the gear surface of the driving gear 18 rotates close to the linkage gear 19, it will drive the linkage gear 19 to rotate together.
