Description

An automatic dust removal device for a distribution box Technical Field

[0001] This utility model relates to the technical field of oil well distribution box maintenance equipment, and in particular to an automatic dust removal device for distribution boxes. Background Technology

[0002] Oil well distribution boxes are essential equipment in oilfield production and management. They are mainly used to convert high-voltage electricity from the upstream power supply into low-voltage electricity suitable for various oil well equipment, so as to meet the power needs of equipment such as pumping unit motors and electric submersible pumps, and ensure that all equipment in the oil well can obtain a stable power supply, thereby ensuring the normal production operation of the oil well.

[0003] However, during long-term operation, a large amount of dust accumulates inside the distribution box. This dust not only affects the heat dissipation of the electrical components inside the distribution box, causing the component temperature to rise and shortening the service life of the distribution box, but also affects the insulation performance of the electrical components, which may cause short circuits and lead to safety accidents such as fires. Traditional dust removal methods usually involve manual cleaning, with operators using brushes, cleaning cotton, and other tools to clean the inside of the distribution box. This method is not only inefficient, but also difficult to clean dust from corners and crevices, and poses safety risks. In existing technologies, some solutions achieve intelligent cleaning by adding control panels, guide rails, and other accessories. However, the problems with these solutions are that the investment cost of the equipment is high, the maintenance costs are high, and the equipment is powered by batteries, which cannot meet the production needs of oilfield equipment. Summary of the Invention

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] The following is a detailed description of the actual working scenario of an automatic dust removal device for a distribution box.

[0025] As shown in Figure 1, the present invention provides an automatic dust removal device for a distribution box, comprising a starting component and a vacuum cleaner 4. The starting component is connected to the vacuum cleaner 4, and the vacuum cleaner 4 is connected to a suction nozzle 5.

[0026] The vacuum cleaner 4 includes a suction port and a discharge port. The suction port is connected to a nozzle 5, and the discharge port is connected to a discharge pipe 6. The upper end of the discharge pipe 6 is connected to the discharge port, and the lower end is connected to the outside of the distribution box, discharging the dust sucked in by the vacuum cleaner 4 to the outside of the distribution box. The lower end of the discharge pipe 6 is equipped with a flap and a limiter. The limiter is located on the side of the flap closer to the inside of the distribution box. The flap allows the dust cleaned by the vacuum cleaner 4 to be discharged along the direction of the discharge pipe 6 to the outside of the distribution box. At the same time, the limiter restricts the flipping direction of the flap, preventing it from opening inward and preventing dust from flowing back into the distribution box. In actual operation, using a plastic discharge pipe can reduce production costs, while using a metal discharge pipe can extend the service life of the device, resulting in higher economic benefits.

[0027] As shown in Figure 2, the inner wall of the nozzle 5 is coated with an anti-static coating to prevent dust from being statically attracted to the nozzle 5, thus preventing incomplete dust removal. The nozzle 5 includes an intake port 51 and a connection port 52. The intake port 51 has a rectangular structure, and the connection port 52 is used to connect to the suction port of the vacuum cleaner 4. The connection port 52 is equipped with a sealing element to make the connection between the nozzle 5 and the vacuum cleaner 4 tighter, preventing dust from overflowing through the connection gap between the nozzle 5 and the vacuum cleaner 4 during the suction process, which would reduce the efficiency of dust removal.

[0028] A connecting channel that gradually narrows towards the connecting port 52 is provided between the suction port 51 and the connecting port 52. This connecting channel has spiral grooves 53, which are evenly distributed around the connecting port 52. These spiral grooves 53 guide the airflow, causing it to move along a spiral trajectory, creating a whirlwind-like effect. This prevents dust from dispersing during suction, making the dust removal process more efficient and improving the overall dust removal efficiency of the device.

[0029] As shown in Figure 1, the starting assembly includes a power switch 1, a transformer 2 inside the distribution box, and a timer switch 3. The power switch 1, transformer 2, and timer switch 3 are connected sequentially via power lines. The timer switch 3 is also connected to the vacuum cleaner 4 via a power line. The power switch 1 controls the power supply to the entire device. The transformer 2 converts the input voltage of the distribution box into the operating voltage required by the vacuum cleaner 4. The timer switch 3 controls the operating time and frequency of the vacuum cleaner 4. Operators can preset the time using the timer switch 3 to control the start and stop of the vacuum cleaner 4, thereby achieving automatic dust removal.

[0030] The following is a detailed description of the actual working scenario of an automatic dust removal device for a distribution box.

[0031] In practical operation, the starting component is connected to the vacuum cleaner 4 via a power cord. The power switch 1 controls the power supply of the entire device. The transformer 2 in the distribution box converts the voltage of the distribution box to the voltage required by the vacuum cleaner 4. The operator controls the start and stop of the vacuum cleaner 4 according to the time preset by the timer switch 3, thereby controlling the running time and frequency of the vacuum cleaner 4. This enables the automatic dust cleaning of the device, ensuring the stable and efficient operation of the distribution box, and reducing labor costs and production costs.

[0032] During use, when the preset time of the time control switch 3 is reached, the vacuum cleaner 4 will automatically turn on to clean the dust. The suction nozzle 5 connected to the suction port of the vacuum cleaner 4 provides airflow guidance through the spiral groove 53, reducing the dispersion of dust, thereby efficiently removing the dust in the distribution box, improving cleaning efficiency, avoiding equipment failure caused by dust accumulation, and extending the service life of electrical components in the distribution box.

[0033] It should be noted that this device uses a 660V oil well distribution box as the basis for the test of the embodiment. The transformer 2 in the selected distribution box can convert the 660V voltage to 380V voltage. If this device is installed in a 380V oil well distribution box, the transformer 2 in the distribution box can be omitted, and the power switch 1 and the time control switch 3 can be directly connected as the starting component of this device.

[0034] In addition, during actual use, it is necessary to strictly check the rated operating voltage and other parameters of each component to ensure that the power supply voltage matches the nominal voltage, prevent accidents such as circuit overload or short circuit caused by incorrect connection, and ensure that the device can maintain a safe and stable operating state.

[0035] It is understood that the above-mentioned embodiments mentioned in this utility model can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this utility model will not elaborate further.
