Description

Technical Field

[0001] The invention relates to the field of oil pumping units, and in particular provides a carbon fiber oil pumping unit. Background Art

[0002] Traditional steel sucker rods have discontinuous operations and require couplings to connect. The piston effect of the couplings will increase ground energy consumption, and the couplings are larger than the sucker rods, making them more prone to eccentric wear with the oil pipes. With the exploitation of China's heavy oil, high water content and ultra-deep wells, the pump inspection cycle of the steel sucker rod collection system has been drastically shortened. Traditional steel sucker rods will also corrode after long-term use and need to be constantly replaced, which is relatively troublesome. Some oil outlets are large in area, and the efficiency of pumping oil using a single pumping pipe is low. Therefore, in order to solve the above problems, it is necessary to design a pumping unit that is not connected to a large area for pumping oil. Summary of the invention

[0005] Preferably, the number of friction grippers in each group is 8-12 and they are evenly located on the same circumference.

[0016] The present invention will be further explained below in conjunction with specific implementation schemes, but the present invention is not limited thereto.

[0017] like Figure 1-4As shown, the present invention provides a carbon fiber oil pumping unit, comprising: a rotating cylinder 1, a plurality of annular baffles 2, a plurality of groups of friction grippers 3, a plurality of carbon fiber oil pumping pipes 4, a wide-mouth oil suction cover 5, a support frame 6 and a lifting and fixing device, wherein a rotating shaft is passed through the center of the rotating cylinder 1, and both ends of the rotating shaft pass through the support frame 6, a plurality of the annular baffles 2 are evenly fixedly connected to the outer surface of the rotating cylinder 1, a plurality of the carbon fiber oil pumping pipes 4 are evenly arranged between each adjacent annular baffle 2, and one end of each of the carbon fiber oil pumping pipes 4 is connected to the rotating cylinder through a fixing frame. 1 side surface is fixedly connected, several groups of friction grippers 3 are evenly arranged on the inner surface of several circular baffles 2, each end face of the friction grippers 3 is overlapped on the outer surface of the carbon fiber oil extraction pipe 4, the wide-mouth oil suction hood 5 is sleeved on the lower end faces of several carbon fiber oil extraction pipes 4, the lifting and fixing device is arranged at one end of the upper surface of the carrier 6, the lifting and fixing device is overlapped with the upper end face of the wide-mouth oil suction hood 5, when using this device, the rotating shaft at the center of the rotating cylinder 1 can rotate in the carrier 6, thereby driving the rotating cylinder 1 to rotate, due to several carbon fibers When one end of the oil pumping pipe 4 is connected to the rotating cylinder 1 through a fixing frame, it is fixed on the rotating cylinder 1, so that it can rotate along with the rotation of the rotating cylinder 1, so that the plurality of carbon fiber oil pumping pipes 4 are either wound around the rotating cylinder 1 or away from the rotating cylinder 1 when rotating. According to the direction of rotation, the plurality of annular baffles 2 located on the side surface of the rotating cylinder 1 are convenient for separating the plurality of carbon fiber oil pumping pipes 4 one by one, so as to prevent mutual contact and mutual influence, and ensure the service life of the carbon fiber oil pumping pipe 4, wherein the friction gripper located on the side surface of each annular baffle 2 is provided. 3. It is easy to retract and release, and the friction is convenient. Each friction clamp 3 is fixedly connected to the annular baffle 2. The wide-mouth oil suction hood 5 is extended into the ground and overlapped with the petroleum liquid surface. Since the wide-mouth oil suction hood 5 has a relatively large area, the oil suction is faster and the efficiency is higher. Since the carbon fiber oil pumping pipe 4 is relatively long and has not been connected in the middle, it is relatively convenient to recycle and has a longer service life. The supporting frame 6 is only used for overall fixing. The lifting and fixing device located on the supporting frame 6 is convenient for lifting and limiting the height of the upper end surface of the wide-mouth oil suction hood 5, which can adapt to descending oil suction or ascending recovery.

[0018] Attached to the instruction manual Figure 1-4 It can be seen that the number of friction grippers 3 in each group is 8-12 and they are evenly located on the same circumference. The larger the number, the better the friction effect.

[0019] Attached to the instruction manual Figure 1-4 It can be seen that each of the friction grippers 3 is made of rubber material. The friction grippers 3 made of this material have a good friction contact effect and are relatively convenient to lift and lower.

[0020] Attached to the instruction manual Figure 1-4 It can be seen that driving devices 8 are provided at both ends of the rotating shaft. The driving device 8 is preferably a driving motor, which can drive the rotating shaft to rotate on both sides. The driving rotation at both ends makes the rotation of the rotating cylinder 1 more stable, and it is more convenient to recover and put down the carbon fiber oil extraction pipe 4.

[0021] Attached to the instruction manual Figure 1-4 It can be known that the lifting and fixing device includes at least one pair of lifting screws 7 and a pushing piece 9 mounted on the lower end surface of each lifting screw 7. The pair of lifting screws 7 vertically penetrate one end of the carrier frame 6. When descending to absorb oil, each lifting screw 7 is twisted upward so that the pushing piece 9 on the lower end surface of each lifting screw 7 is away from the lifting screw 7, and the descent of the wide-mouth oil suction hood 5 is not restricted. The lifting and fixing device is driven by a pair of driving devices 8 to descend. When the wide-mouth oil suction hood 5 is recovered, that is, when no oil is sucked, the carbon fiber oil suction pipe 5 is recovered under the reverse drive of a pair of driving devices 8. Each lifting screw 7 is twisted downward so that the lower end surface of each pushing piece 9 overlaps with the upper end surface of the wide-mouth oil suction hood 5, so that the wide-mouth oil suction hood 5 is no longer recovered and fixed, which is convenient for restriction and good fixation.

[0022] The detailed description of the present invention is written in a progressive manner, emphasizing the differences between the various implementations, and similar parts thereof can be referred to each other.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
