Technical Field
[0001] This utility model relates to the field of oil pumping unit technology, and in particular to a photovoltaic integrated vertical oil pumping unit device. Background Technology
[0002] Traditional pumping units (such as beam pumping units) suffer from high energy consumption, low operating efficiency, and low motor load rate. Their overall balance is not ideal, they have a significant impact on the power grid, and their stroke and stroke adjustment range is limited. They can no longer meet the expansion needs of domestic oil and gas exploration and development in the field of deep and ultra-deep wells. In addition, traditional pumping units rely on the power grid for power supply, which makes them difficult to operate in remote oil fields with no power grid or unstable power grid.
[0003] To meet the demand for higher-performance equipment and new energy power supply in oil and gas exploration projects, vertical pumping units and photovoltaic systems have been widely used in various oil fields. However, the photovoltaic systems mentioned above are usually civil engineering photovoltaic systems or wall-mounted photovoltaic systems, which are used as external power sources to supply power to the vertical pumping units. The tower structure of the vertical pumping units is not fully utilized, resulting in a low degree of integration of the entire system. Utility Model Content

[0012] The photovoltaic bracket has a support base fixed at its end, and the support base and the end of the photovoltaic bracket together form an assembly space for installing the first base. The first rotating shaft passes through the support base and is rotatably connected to the support base via a bearing.
[0013] The main body of the vertical pumping unit includes a cover for protecting the external power transmission mechanism. The cover is fixed to the columnar tower, and one or more photovoltaic panels are fixed to the side of the cover facing away from the columnar tower.

Detailed Implementation
[0018] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0020] Furthermore, in this utility model, the directional terms "front" and "rear" are relative to the working end direction of the spindle, that is, the direction closer to the working end of the spindle is "front" and the direction farther away from the working end of the spindle is "rear". The directional terms "inner" and "outer" are relative to the center direction of the spindle, that is, the direction closer to the center of the spindle is "inner" and the direction farther away from the center of the spindle is "outer".
[0021] like Figure 1 As shown, this utility model provides a photovoltaic integrated vertical pumping unit device, including a vertical pumping unit body 100, a photovoltaic unit, an energy storage unit 400, a hybrid inverter control unit 300, and a controller unit 500. The photovoltaic unit includes a plurality of photovoltaic panels 200, each of which is spaced along the height direction on the outside of the columnar tower 101 of the vertical pumping unit body 100. Compared with the prior art, this invention fully utilizes the tower structure of the vertical pumping unit to achieve integrated photovoltaic unit and vertical pumping unit. Figure 9 As shown, a photovoltaic unit composed of photovoltaic panels 200 is electrically connected to an energy storage unit 400 via a DC / DC converter in a hybrid inverter control unit 300. Preferably, the energy storage unit includes multiple energy storage battery modules. The input terminal of the DC / DC converter is connected to the photovoltaic unit, and its output terminal is connected to each energy storage battery module, storing the electrical energy converted from the photovoltaic unit within the energy storage unit. The photovoltaic unit and the energy storage unit 400 are electrically connected to the controller unit 500 via a DC / AC inverter in the hybrid inverter control unit 300. The input terminals of the DC / AC inverter are connected to both the photovoltaic unit and the energy storage unit 400, and its output terminal is connected to the controller unit 500, converting the electrical energy converted from the photovoltaic unit and the electrical energy in the energy storage batteries into AC power to supply the load of the controller unit 500. Specifically, the hybrid inverter control unit 300 can be an MPS hybrid inverter, such as MPS0050 / MPS0250, etc.; the controller unit 500... The frequency converter is electrically connected to the motor of the vertical pumping unit 100. By identifying the power supply mode in the hybrid inverter control unit 300, the frequency converter changes the speed of the vertical pumping unit motor, thereby altering the pumping unit's stroke rate. When there is sufficient sunlight, the photovoltaic unit's power generation exceeds the load power required by the controller unit 500. The photovoltaic unit prioritizes powering the pumping unit and stores excess energy in the energy storage unit 400. At this time, the frequency converter increases the motor speed to increase the pumping unit's stroke rate. When there is insufficient sunlight, the photovoltaic unit... The power generation of the photovoltaic unit 500 cannot meet the load requirements of the controller unit 500. The photovoltaic unit and the energy storage unit 400 jointly supply power to the pumping unit. At this time, the frequency converter reduces the motor speed to reduce the pumping unit's stroke. Under conditions of no light, such as at night, the energy storage unit 400 supplies power to the pumping unit alone. At this time, the frequency converter can be in standby mode. Preferably, the frequency converter is a four-quadrant frequency converter, such as ACS800 / ACS880, to achieve efficient matching between new energy and the pumping unit and improve the utilization rate of the photovoltaic unit.
[0022] In a further preferred embodiment, to improve the integration of the device, the energy storage unit 400, the hybrid inverter control unit 300, and the controller unit 500 are all fixed to the base 102 of the vertical pumping unit body 100 in a cabinet-mounted manner.
[0023] like Figure 1 and Figure 2 As shown, several photovoltaic supports 600 are fixed to the outside of the columnar tower 101. Each photovoltaic support 600 is movably connected to a photovoltaic panel 200 via a photovoltaic adjustment component 700, and the photovoltaic panel 200 is equipped with a light sensor. The controller unit 500 includes a monitoring controller, which receives signals from each light sensor and controls the corresponding photovoltaic adjustment component 700 to drive the connected photovoltaic panel 200. Through the communication and linkage between the monitoring controller, the light sensor, and the photovoltaic adjustment component 700, the photovoltaic panel 200 can automatically adjust its tilt angle on the photovoltaic support 600 according to the solar altitude angle, thereby realizing automatic light tracking setting of the photovoltaic panel 200 and maximizing its light capture efficiency.
[0024] To maximize the use of the outer space of the column tower 101, the photovoltaic support 600 is located on the side of the column tower 101 facing away from the power transmission mechanism. Specifically, in this solution, the power transmission mechanism is a belt; in other embodiments, the power transmission mechanism can also be a steel wire rope, etc. The photovoltaic support 600 is divided into two groups, and the two groups of photovoltaic support 600 are arranged symmetrically about the longitudinal axis of the column tower 101. Preferably, the central axes of the two photovoltaic support 600 arranged opposite each other have a certain angle, so that the photovoltaic panels 200 at the ends of the photovoltaic support 600 are arranged in a wing-like shape on the outside of the column tower 101. This avoids being blocked by the vertical pumping unit body 100.
[0025] Further preferred, such as Figure 3 As shown, the vertical pumping unit body 100 includes a cover 103 for protecting the external power transmission mechanism (belt). The cover 103 is fixed on the column tower 101. One or more photovoltaic panels 200 are fixed on the side of the cover 103 facing away from the column tower 101 to form a fixed photovoltaic unit. In this scheme, the photovoltaic panels 200 constituting the fixed photovoltaic panel 200 unit are flexible photovoltaic panels 200 to fit the curved structure of the outer side of the cover 103. If multiple photovoltaic panels 200 are used, the photovoltaic panels 200 are arranged at intervals along the height direction of the cover 103.
[0026] Preferably, in this solution, the light sensor can be a four-channel photosensitive sensor, and the monitoring controller can be a dual-axis light-tracking controller, such as...

The deflection seat 1 is rotatably connected to the photovoltaic bracket 600 via a first rotating shaft 5. The pitch seat 2 is welded and fixed to the back side of the photovoltaic panel 200 via a bracket and is rotatably connected to the deflection seat 1 via a second rotating shaft 6. The deflection adjustment component 3 and the pitch adjustment component 4 are respectively communicatively connected to a dual-axis tracking controller. Under the control of the dual-axis tracking controller, the deflection adjustment component 3 drives the photovoltaic panel 200 to deflect relative to the photovoltaic bracket 600 around the first rotating shaft 5, and the pitch adjustment component 4 drives the photovoltaic panel 200 to pitch relative to the photovoltaic bracket 600 around the second rotating shaft 6, thus completing the dual-axis multi-angle adjustment of the photovoltaic panel 200.

The first servo motor 301 is fixed outside the first active chamber and is connected to the first worm gear 303 for transmission. The first worm wheel 304 is formed... The first slewing bearing 305 is located on the outer circumference of the first slewing bearing 305 and meshes with the first worm gear 303. The inner ring of the first slewing bearing 305 and the bottom of the first base 302 are fixedly connected to the end of the photovoltaic bracket 600 by bolts. The outer ring of the first slewing bearing 305 is fixedly connected to the deflection seat 1 via the first rotating shaft 5. Specifically, the bottom of the first rotating shaft 5 has a disc seat, which is fixed to the outer ring of the first slewing bearing 305 by bolts. The top of the first rotating shaft 5 passes through the middle of the deflection seat 1 and is welded and fixed to the deflection seat 1.
[0028] Preferably, in order to improve the rotational stability of the first rotating shaft 5, such as Figure 5 As shown, a support base 9 is fixed to the end of the photovoltaic bracket 600, and the support base 9 and the end of the photovoltaic bracket 600 together form an assembly space for installing the first base 302. The first rotating shaft 5 passes through the support base 9 and is rotatably connected to the support base 9 via the bearing component 10.
[0029] like Figure 7 As shown, the deflection seat 1 has a pair of first ear plates 7 facing the photovoltaic panel 200, and the pitch seat 2 has a pair of second ear plates 8 facing away from the photovoltaic panel 200. Specifically, the first ear plates 7 are located inside the second ear plates 8, and the end of the second rotating shaft 6 passes through the first ear plates 7 and is welded and fixed to the second ear plates 8. More preferably, the through-hole of the first ear plates 7 is rotatably connected to the second rotating shaft 6 via a bearing 10.
[0030] like Figure 8 As shown, the pitch adjustment component 4 includes a second base 402, a second servo motor 401, a second worm gear 403, a second worm wheel 404, and a second slewing bearing 405. The second base 402 is welded or bolted to the inner side of the deflection seat 1.

The second servo motor 401 is fixed to the outer side of the second active chamber and is connected to the second worm gear 403 for transmission. The second worm wheel 404 is sleeved on the outer side of the first rotating shaft 5 through a through hole and is connected to the second worm gear 403. The outer ring of the second rotary bearing 405 is fixedly connected to the second base 402 by bolts, and the inner ring of the second rotary bearing 405 is fixedly connected to the second worm gear 404 and the second rotating shaft 6. Specifically, a connecting sleeve for fitting onto the second rotating shaft 6 is formed on the inner ring of the second rotary bearing 405. The outer edge of the connecting sleeve is welded and fixed to the surface of the second rotating shaft 6. The inner ring of the second rotary bearing 405 located outside the connecting sleeve is fixedly connected to the second worm gear 404 by bolts. More preferably, there are two second rotary bearings 405, symmetrically arranged on the left and right sides of the second worm gear 404.

It automatically adjusts the tilt angle of the photovoltaic panel 200 according to the solar altitude angle.
