Description

Technical Field

[0001] This utility model relates to the field of energy-saving control cabinet technology, and in particular to an energy-saving control cabinet for an oil pumping unit. Background Technology

[0002] Energy-saving control cabinets for oil pumping units are electrical devices specifically designed for the oil pumping unit industry. They aim to improve energy efficiency, reduce energy consumption, and extend equipment lifespan. With global energy shortages and increasing environmental awareness, the application of energy-saving control cabinets has become increasingly important. This equipment can significantly reduce the power consumption of oil pumping units during operation and help reduce operating costs for businesses. The core function of the energy-saving control cabinet is to monitor and adjust the operating status of the oil pumping unit in real time through intelligent control technology. It can flexibly adjust the motor's operating parameters according to the actual needs of the oil well, avoiding energy waste caused by over-operation. At the same time, the control cabinet also integrates multiple protection functions, such as overload protection, undervoltage protection, and short-circuit protection, to ensure that the equipment operates under safe and reliable conditions.

[0003] During operation, energy-saving control cabinets for oil pumping units integrate various electronic components, such as frequency converters, relays, and power modules. As a result, some electrical energy is lost as heat during power conversion and transmission, causing the temperature inside the control cabinet to rise. Some existing energy-saving control cabinets for oil pumping units have their bottoms very close to the ground. Since heat dissipation requires air convection to remove heat, placing them close to the ground reduces airflow below, preventing effective heat dissipation. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an energy-saving control cabinet for oil pumping units.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy-saving control cabinet for an oil pumping unit includes a cabinet body. A base is provided at the bottom of the cabinet body. Two adjusting plates are symmetrically rotatably connected inside the base, and the two adjusting plates are inclined. Adjusting rollers are rotatably connected to one side of each of the two adjusting plates. Hydraulic rods are fixedly fitted onto the surfaces of the two adjusting rollers away from the adjusting plates. The other ends of the two hydraulic rods are rotatably connected to the inner surface of the base. Lifting mechanisms for raising and lowering the cabinet body are provided at the ends of the two adjusting plates near the cabinet body. A third ventilation opening is provided at the bottom of the cabinet body, and a fan is installed inside the third ventilation opening. Two second baffles are symmetrically slidably connected inside the third ventilation opening. Moving mechanisms for moving the second baffles are provided on the surfaces of the two second baffles near the adjusting plates. A first ventilation opening is provided at the top of the cabinet body near the third ventilation opening. Two third constraint grooves are symmetrically formed inside the first ventilation opening, and closing mechanisms for closing the first ventilation opening are provided inside the two third constraint grooves. The adjusting plates allow the bottom of the cabinet body to be moved upwards.

[0007] As a further embodiment of this utility model, the lifting mechanism includes a first slide groove, which is opened at the bottom of the cabinet. Two first constraint grooves are symmetrically opened inside the first slide groove. The same constraint roller is slidably connected inside the two first constraint grooves. The constraint roller is fixedly connected to one end of the adjustment plate. By setting the first constraint grooves, the cabinet can be raised and lowered.

[0008] As a further embodiment of this utility model, the moving mechanism includes two second constraint grooves, which are respectively opened in two third ventilation openings and one side inside the two first constraint grooves. The second baffle is slidably connected inside the second constraint groove and rotatably connected to the surface of the constraint roller. The second baffle can be moved by setting the second constraint grooves.

[0009] As a further embodiment of this utility model, the closing mechanism includes a first baffle, which is slidably connected to the inside of a third constraint groove. A third sliding groove is provided at the bottom of the first baffle, and a second rack is fixedly connected to one side inside the third sliding groove. A second gear is fitted on the surface of the second rack, and a rotating mechanism for rotating the second gear is provided at the bottom of the second gear. By setting the first baffle, the first vent can be closed.

[0010] As a further embodiment of this utility model, the rotating mechanism includes a first rotating shaft, which is rotatably connected to the inside of the cabinet. The first rotating shaft is fixedly connected to the bottom of the second gear. A first synchronous wheel is fixedly sleeved on the bottom of the first rotating shaft. A second sliding groove is opened on the top of the second baffle. A first rack is fixedly connected to one side of the second sliding groove. A second rotating shaft is rotatably connected to the top of the first sliding groove near the first rack. A first gear is sleeved on the surface of the second rotating shaft near the first rack. The first gear and the first rack cooperate with each other. A second synchronous wheel is sleeved on the surface of the second rotating shaft near the first synchronous wheel. The second synchronous wheel and the first synchronous wheel are sleeved with the same synchronous belt. Second ventilation openings are opened on both sides of the cabinet. Multiple louvers are provided inside each of the two second ventilation openings. The multiple louvers are vertically and evenly arranged. A cabinet door is rotatably connected to one side of the cabinet. The second gear can be rotated by the setting of the first rotating shaft.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a technical solution of supporting the cabinet with adjusting plates, so that the bottom of the cabinet can be far away from the ground. This effectively solves the problem that when the bottom of the energy-saving control cabinet for the generator is close to the ground, heat dissipation requires air convection to remove heat. Placing it close to the ground reduces the airflow below, resulting in ineffective heat dissipation. The cabinet is installed on top of two adjusting plates, so when the angle of the two adjusting plates changes, the bottom of the cabinet can be far away from the ground, thereby increasing the airflow speed below the cabinet and enabling the cabinet to dissipate heat better.

The constraint roller 204 is fixedly connected to one end of the adjusting plate 201. The cabinet 1 can be lifted and lowered by the setting of the first constraint grooves 108.

[0022] Reference Figure 3 and Figure 4 In a preferred embodiment, the moving mechanism includes two second constraint grooves 109, which are respectively opened on one side inside the two third vents 106 and the two first constraint grooves 108. A second baffle 205 is slidably connected inside the second constraint grooves 109 and rotatably connected to the surface of the constraint roller 204. The second baffle 205 can be moved by the setting of the second constraint grooves 109.

[0023] Reference Figure 3 and Figure 5 In a preferred embodiment, the sealing mechanism includes a first baffle 3, which is slidably connected to the inside of the third constraint groove 103. The bottom of the first baffle 3 is provided with a third sliding groove 301. A second rack 302 is fixedly connected to one side inside the third sliding groove 301.

By setting the first baffle 3, the first vent 102 can be sealed.

[0024] Reference Figure 4 and Figure 5 In a preferred embodiment, the rotating mechanism includes a first rotating shaft 303, which is rotatably connected to the inside of the cabinet 1. The first rotating shaft 303 is fixedly connected to the bottom of the second gear 304. A first synchronous pulley 305 is fixedly sleeved on the bottom of the first rotating shaft 303. A second sliding groove 206 is formed on the top of the second baffle 205. A first rack 207 is fixedly connected to one side of the inside of the second sliding groove 206. The second rotating shaft 306 is rotatably connected to the top of the side of the first sliding groove 207 near the first rack 207.

Multiple louvers 105 are provided inside each of the two second ventilation openings 104, and the multiple louvers 105 are arranged vertically and evenly. A cabinet door 101 is rotatably connected to one side of the cabinet 1. The second gear 304 can be rotated by the first rotating shaft 303.

[0025] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the internal temperature of the cabinet 1 is too high, the two hydraulic rods 203 in the base 2 can be activated. Both hydraulic rods 203 cooperate with the adjusting plate 201 through the adjusting roller 202. After the hydraulic rods 203 are activated, the angle of the adjusting plate 201 can be adjusted. The cabinet 1 is installed on top of the two adjusting plates 201. Therefore, when the angle of the two adjusting plates 201 changes, the bottom of the cabinet 1 can be moved away from the ground, thereby increasing the airflow velocity below the cabinet 1 and enabling the cabinet 1 to dissipate heat better. Two second baffles 205 are also installed at the bottom of the cabinet 1. Both second baffles 205 cooperate with the adjusting plate 201. Therefore, when the angle of the adjusting plate 201 changes, the second baffles 205 can be moved synchronously. A first rack 207 is installed on the top of the second baffle 205, and a first gear 30 is fitted on the surface of the first rack 207. 7. Thus, the first rack 207, driven by the second baffle 205, can make the first gear 307 rotate. A timing belt 309 is installed on the top of the first gear 307, and the other end of the timing belt 309 is installed on the surface of the first rotating shaft 303. A second gear 304 is installed on the top of the first rotating shaft 303. Thus, driven by the timing belt 309, when the first gear 307 rotates, the second gear 304 will also rotate synchronously. The second gear 304 cooperates with the second rack 302 at the bottom of the first baffle 3. Since the first rack 207 and the second rack 302 are set on one side, when the two second baffles 205 move away from each other, the two first baffles 3 will also move away synchronously, so that the third vent 106 and the first vent 102 can open synchronously. A fan 4 is also installed inside the third vent 106. Thus, after the fan 4 is started, the airflow inside the cabinet 1 can be further accelerated, so that the temperature inside the cabinet 1 can be reduced.
