Description

Technical Field

[0001] This utility model relates to the field of petroleum extraction technology, and in particular to a fan gantry support for a hybrid power pumping unit. Background Technology

[0002] Oil pumping units, also commonly known as oil pumps or oil extraction equipment, are indispensable and crucial machines in oil extraction. They are primarily used to extract crude oil from underground oil reservoirs, raising the deep oil to the surface through a series of power drives and mechanical transmissions for subsequent processing. The working principle of an oil pumping unit typically involves an electric motor or other power source driving the oil, which is then transmitted to the pump or sucker rod via a reducer and transmission system. These pumps or rods operate deep underground, using negative pressure or mechanical force to extract oil from rock pores and transport it to the surface along tubing. During oil extraction, the performance of the oil pumping unit directly affects oil production and extraction efficiency. Therefore, high standards are placed on the design, manufacture, and maintenance of oil pumping units. Advanced oil pumping units not only improve the efficiency and production of oil extraction but also reduce energy consumption and environmental pollution, achieving green and efficient oil extraction. The power sources for oil pumping units are mainly diesel engines and electric motors; existing technologies also include equipment that directly uses wind turbines to power the pumping process.

[0003] Chinese invention patent CN112593898A discloses a wind-powered hybrid power pumping unit system and its operating method. This system cleverly integrates wind energy absorption and electric power technologies to improve energy efficiency and reduce operating costs. The system mainly includes core components such as a wind energy absorption device, a hybrid power transmission mechanism, an electric motor, a pumping unit, a generator, a battery, and a control cabinet. The hybrid power transmission mechanism is designed with two power input ends, capable of simultaneously receiving power from different energy sources. One power input end is connected to the power output end of the wind energy absorption device to absorb and utilize wind energy when it is abundant; the other power input end is connected to one end of the electric motor's dual output shaft, using the power provided by the electric motor to drive the pumping unit. The electric motor adopts a dual output shaft design, with its other end connected to the power input end of the generator. When the electric motor is not used as the primary power source, it can be used as a generator, converting surplus energy into electrical energy and storing it in the battery for future use. The control cabinet is responsible for the coordination and control of the entire system, ensuring that the wind energy absorption device, electric motor, generator, and other components operate efficiently and stably. This system boasts advantages such as simplicity, reliability, straightforward control logic, and high wind energy utilization. Furthermore, its rigid mechanical system results in a simple structure and low cost, making retrofitting existing oil pumping unit systems relatively inexpensive. In addition, the system offers significant energy savings, positively impacting the overall energy efficiency of oil pumping unit systems. Existing wind power technologies require separate foundations and higher fan locations, increasing floor space and wasting materials. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a gantry support for a hybrid power pumping unit, comprising a crossbeam, with a gantry leg one and a gantry leg two fixedly mounted at both ends of the crossbeam. The gantry leg one and gantry leg two are fixedly installed on the top of the pumping unit. Channel steel legs are fixedly mounted on the crossbeam, and fan assemblies are mounted on the channel steel legs. Through this technical solution, the gantry leg one and gantry leg two are directly installed on the pumping unit, saving materials by utilizing the pumping unit tower. The fan height can be supported by the pumping unit to a certain height, saving floor space and eliminating the need for a separate foundation.

[0005] Furthermore, reinforcing ribs are fixedly installed on the lower sides of both ends of the crossbeam and are respectively fixed to the first gantry leg and the second gantry leg.

[0006] Furthermore, multiple reinforcing rods are fixedly installed on the channel steel legs, which can serve as both connection and reinforcement for the channel steel legs and as stepping rods for climbing up and down.

[0007] Furthermore, the fan assembly includes a connecting flange, which is fixedly mounted on a channel steel support leg. A column assembly is fixedly mounted on the connecting flange. A slewing bearing flange connecting plate is mounted on the column assembly. A slewing bearing is mounted on the slewing bearing flange connecting plate and is driven to rotate by a slewing reducer with a motor. A transmission system platform is fixedly mounted on the slewing bearing, and a fan wheel is mounted on the transmission system platform.

[0008] Furthermore, a maintenance platform is fixedly mounted on the lower side of the transmission system platform, and the maintenance platform rotates with the transmission system platform. Through this technical solution, when the wind turbine is yaw adjusted, the maintenance platform also rotates accordingly without interference, and can maintain a large adjustment range, making it relatively safe for personnel to perform maintenance on the maintenance platform.

[0009] Furthermore, the transmission system platform and the maintenance platform are fixedly connected by four maintenance platform hangers.

[0010] Furthermore, the maintenance platform is equipped with a maintenance platform guardrail.

[0011] Furthermore, a transition platform is fixedly installed at the lower end of the maintenance platform for transitioning between the channel steel support legs and the maintenance platform.

[0012] The advantages of this utility model compared with the prior art are:

[0013] (1) Through the technical solution of the present invention, the first and second gantry legs can be directly installed on the pumping unit, which can save materials. The height of the fan can be supported by the pumping unit to a certain height, and it shares a foundation with the pumping unit, so there is no need to make a separate foundation, thus saving the floor space. Due to the use of the pumping unit tower, compared with the traditional wind turbine tower, 1 / 3 of the wind turbine support steel structure is saved.

[0014] (2) With the technical solution of the present invention, when the wind turbine is yaw adjusted, the maintenance platform will also rotate accordingly without interference, and can maintain a large adjustment position, and people will be relatively safe when performing maintenance on the maintenance platform.

Detailed Implementation

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 The diagram shows a gantry support for a hybrid power pumping unit, comprising a crossbeam 3. Gantry legs 1 and 2 are fixedly mounted at both ends of the crossbeam 3, satisfying both support strength requirements and serving as a connection between the pumping unit and the entire wind turbine generator set. In this embodiment, the crossbeam 3 is circular, and a diagonal bracing structure 21 is mounted on it. The lower end of the diagonal bracing structure 21 is installed on the reducer of the pumping unit's upper platform, making the gantry support structure more stable and allowing for manual passage from the pumping unit's upper platform to the gantry. Gantry legs 1 and 2 are welded to both ends of the crossbeam 3. To enhance load-bearing capacity, reinforcing ribs 4 are fixedly installed at the connection between gantry legs 1 and the crossbeam 3. The connection between the crossbeam 3 and the second gantry leg 2 is also fixed with reinforcing ribs 4, all of which are fixed by welding. The first gantry leg 1 and the second gantry leg 2 are installed on the top of the pumping unit with flange bolts. The top of the pumping unit has a reserved opening. The pumping unit acts as a base to raise the overall height, which saves some of the steel structure material for the fan support. The fan does not need to be built with a separate foundation, which also saves the floor space. The middle position of the crossbeam 3 is fixed with a channel steel leg 5. The channel steel leg 5 is also fixed to the crossbeam 3 by welding. Multiple footboards 6 are set at equal intervals on the channel steel leg 5 for reinforcement. The footboards 6 can be used as ladders to climb upwards for construction. The top of the channel steel leg 5 is equipped with a fan assembly.

[0022] In this embodiment, the fan assembly includes a connecting flange 7, which is bolted to the top of the channel steel support leg 5. A column assembly 8 is fixedly mounted on the upper side of the connecting flange 7 by welding. A slewing bearing flange connecting plate 10 is fixedly mounted on the top of the column assembly 8. A slewing bearing 11 is mounted on the top of the slewing bearing flange connecting plate 10. A slewing reducer 9 with a motor is fixedly mounted on the slewing bearing 11, driving the slewing bearing 11 to rotate on the slewing bearing flange connecting plate 10. A transmission system platform 12 is fixedly mounted on the slewing bearing 11. A generator 13 and a speed increaser 20 are fixedly mounted on the upper end of the transmission system platform 12. The output end of the generator 13 is connected to the speed increaser 20 via a coupling 19. The hub of the wind turbine 14 is rotatably mounted on the speed increaser 20. The wind turbine 14 is a key component of the wind turbine. It consists of several large blades, which are carefully designed with optimized shapes and angles to maximize wind energy capture. When wind blows over the blades, they begin to rotate, driving the wind turbine to turn. When yaw adjustment is needed, the slewing reducer 9 with its motor operates, driving the slewing bearing 11 and the transmission platform 12 to rotate, thereby driving the wind turbine 14 to change its windward direction. The generator 13 is connected to the wind turbine shaft. When the wind turbine 14 rotates, the rotor inside the generator 13 also rotates. Inside the generator 13, there is a magnetic field and one or more coils. When the rotor rotates, the coils move in the magnetic field, generating current according to the principle of electromagnetic induction. This current is the electrical energy produced by the wind turbine.

[0023] The control system of a wind turbine is responsible for monitoring and regulating the entire power generation process. It continuously detects wind speed, wind direction, and other environmental factors, and adjusts the orientation and speed of the rotor accordingly to ensure that the wind turbine always operates at its optimal condition. In addition, the control system is also responsible for protecting the wind turbine from excessive loads and malfunctions.

[0024] Four maintenance platform booms 15 are fixedly installed at the lower end of the transmission system platform 12. The four maintenance platform booms 15 are respectively fixed to the four corners of the transmission system platform 12 by bolts. The lower ends of the four maintenance platform booms 15 are jointly fixedly installed with a maintenance platform 17. The maintenance platform 17 is fixedly installed with a maintenance platform railing 16. Construction personnel can stand on the maintenance platform 17 to carry out maintenance work. The maintenance platform railing 16 can protect the construction personnel. A circular hole is provided on the connecting flange 7. The diameter of the circular hole is larger than the diameter of the column assembly 8 and is coaxial with the column assembly 8. When the transmission system platform 12 rotates, the maintenance platform 17 will also rotate. In this way, when yaw adjustment is performed, the wind turbine 14 will not interfere with the maintenance platform 17 and the maintenance platform railing 16. A transition platform 18 is fixedly installed at the lower end of the maintenance platform 17 by bolts. The transition platform 18 is also provided with railings on both sides. An opening is provided at the position where the transition platform 18 is installed on the maintenance platform 17. Construction personnel climb up from the transition platform 18 and reach the maintenance platform 17 through the opening.
