Diesel tank sensor oil stain prevention device and preparation process thereof

Abstract

The invention discloses a diesel tank sensor oil stain prevention device. The device comprises an outer shell, an end cover is installed at the front end of the outer shell, an isolation plate is installed on the end cover, a plurality of through holes are formed in the isolation plate, a battery pack is installed in the outer shell, a circuit board is installed on the battery pack, a sensor head is installed at one end of the circuit board, and a dust collection cavity is formed in the lower portion of one end of the circuit board. One end of the dust collection cavity is communicated with a dust suction pipe, the end of the dust suction pipe is connected with the isolation plate in an attached mode, at least three first connecting blocks are arranged at the upper end of the dust collection cavity, positioning columns are arranged on the first connecting blocks, at least three second connecting blocks are further arranged at the upper end of the dust collection cavity, and clamping heads are arranged on the second connecting blocks. According to the invention, the safety protection of the sensor can be realized, the precision of the sensor is ensured, and the oil stain can be stored.

Description

Technical field [0001] The present invention belongs to the technical field of diesel tank sensor, and more particularly to a diesel tank sensor oil-proof device and a preparation process thereof. Background technique [0002] The fuel tank is a container for fuel on the aircraft or car, which is a special container that stores hydraulic oil or hydraulic fluid in a hydraulic system. The fuel tank can be divided into two types of open fuel tanks and closed fuel tanks. The fuel tank must have a sufficiently large volume; the oil absorbing tube and the oil return pipe should be inserted below the lowest liquid level to prevent air bubbles from sucking and illegal splashing; the distance between the suction tube and the oil return pipe should be as far as possible, between Set the separator; in order to keep the oil clean, the fuel tank should have a peripheral sealed cover, and the air filter is equipped with a cover; the bottom of the fuel tank should be from 150 mm or more; the an...

AI Technical Summary

Problems solved by technology

The oil tank must have a large enough volume; the oil suction pipe and the oil return pipe should be inserted below the minimum liquid level to prevent air suction and return oil splashing to produce air bubbles; the distance between the oil suction pipe and the oil return pipe should be as far as possible, and the distance between them should be Set up partitions; in order to keep the oil clean, the oil tank should have a peripherally sealed cover plate with an air filter installed; the bottom of the oil tank should be more than 150mm from the ground; full attention should be paid to the anti-corrosion treatment of the inner surface of the oil tank, and When the fuel tank is in use, there will be a large number of sensors to detect the fuel tank, but when the sensor is detected, the oil will pollute the sensor, so that the detection accuracy of the sensor is not enough when detecting, and it is easy to occur The deviation of data information, so it is urgent to realize the safety protection of the sensor and ensure the safety of the sensor. However, there are still various problems in the various anti-oil pollution devices of the sensor on the market.

[0003] For example, the authorized announcement number is CN112729360A, which discloses a protective cover suitable for the displacement sensor of the hot coil box, which belongs to the technical field of protective cover, including: the main body of the protective cover, the cable clamp, the cooling air pipe, the bottom plate, the top cover. Installation, the exhaust port is downward, the high-pressure air enters from the cooling air duct exhaust port of the cooling air duct, and is discharged from the exhaust port. While the internal displacement sensor achieves the purpose of cooling down, it makes the inside of the protective cover form a positive pressure, effectively preventing water vapor and dust from entering. Intrusion, the oil leakage generated by the hydraulic cylinder will also be collected through the oil guide groove and then discharged from the discharge port. Although it can prevent oil from corroding the displacement sensor, it is durable and avoids the cable reconnection caused by the mismatch between the original protective cover and the new hydraulic cylinder. The cumbersome work of laying saves time, but it does not solve the problems that the existing sensor oil pollution prevention device cannot collect oil pollution when it is in use, and cannot realize the safety protection of sensors, etc. For this reason, we propose A diesel tank sensor oil pollution prevention device and its preparation process
