Abstract
Description
Technical Field
[0001] This utility model relates to the field of helium detection technology, specifically a remote helium detection device. Background Technology
[0002] Helium gas detection, as a high-precision detection method, is mainly used to check for leaks in precision workpieces or equipment, and is particularly widely used in vacuum and cryogenic containers.
[0003] Currently, helium testing of cryogenic storage tanks is mostly done manually. Testers need to wear safety belts and other protective equipment, climb ladders or scaffolds to the surface of the tank, and use portable helium testing instruments to test the body, welds, pipes, valves and instruments and other parts prone to leakage.
[0004] This traditional method presents significant safety hazards, with high-altitude operations posing a prominent risk. Personnel are prone to falls due to equipment aging or operational errors during climbing. Furthermore, personnel operating on the tank while focused on the monitoring screen are highly susceptible to falling. While existing technologies include automated testing equipment based on magnetic carts, their structural adaptability is limited. Most magnetic carts use rigid connecting frames, making it difficult to adapt to the curved surface variations of the tank's outer wall. This results in unstable spacing between the testing components and the tank surface, affecting testing accuracy and potentially causing equipment falls due to fluctuations in adsorption force. Therefore, a remote helium detection device is needed to address these issues. Utility Model Content
[0005] The purpose of this invention is to provide a remote helium detection device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a remote helium detection device, including a frame, on which a remote helium detection module is provided. The frame is composed of a first frame and a second frame connected by a first universal joint. An active magnetic wheel is connected to the first frame, and a driven magnetic wheel is connected to the second frame. An adjustment component is provided between the opposite ends of the first frame and the second frame, and the adjustment component is used to drive the first frame and the second frame to rotate relative to each other to achieve steering adjustment.
[0007] Preferably, the adjustment assembly includes an electric push rod, a second universal connector, and a third universal connector. One end of the first frame is connected to one end of the electric push rod via the second universal connector, and one end of the second frame is connected to the output end of the electric push rod via the third universal connector.
[0008] Preferably, the second universal connector includes two sets of first adjusting seats and two sets of second adjusting seats. The first frame is connected to two sets of horizontally rotatable first adjusting seats. The upper end of each set of first adjusting seats is hinged to a set of vertically rotatable second adjusting seats. The second adjusting seats are connected to one end of the electric push rod.
[0009] Preferably, the third universal connector includes a third adjusting seat and a fourth adjusting seat. The output end of the electric push rod is connected to the third adjusting seat.

The universal bases are universally connected to a set of ball joints, and the other end of the ball joints is connected to the corresponding frame.
[0011] Preferably, a set of dual-output shaft motors is installed in the inner cavity of the first frame, and each of the two output ends of the dual-output shaft motors is connected to a set of active magnetic wheels. A set of support members is installed at the top of the first frame, and a battery for power supply is installed in the inner cavity of the support members. A helium remote detection module is installed at the top of the support members.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model eliminates the need for inspection personnel to climb to heights, avoiding falls due to equipment aging or operational errors, thus improving operational safety. Employing a remote inspection method, the vehicle frame connects the first and second frames via a first universal joint. Adjustment components enable steering adjustment, better adapting to the curved surface changes of the tank's outer wall. This results in a more stable distance between the helium remote inspection module and the tank surface, improving inspection accuracy. The structural design of the first and second frames, combined with active and driven magnetic wheels, better suits the curved surface of the tank, reducing the risk of equipment falls due to fluctuations in adsorption force and ensuring the stability of the inspection process.
[0014] 2. The electric push rods and the frame of this utility model are connected by universal joints. The extension and retraction of the two sets of electric push rods can easily adjust the steering direction of the first and second frames to meet the steering requirements under different working conditions. The first adjustment seat of the second universal joint effectively assists the steering by rotating horizontally, and the second adjustment seat cooperates with the first universal joint by rotating up and down, which significantly improves the fit between the first and second frames and the curvature of the tank, and enhances the adaptability of the device to the surface of the tank. The structural design of the third universal joint assists the relative rotation of the first and second frames, further enhancing the adaptability of the device to changes in the curvature of the tank, ensuring the stability of the distance between the detection component and the surface of the tank, and improving the detection accuracy. The universal joint seat and ball joint of the first universal joint achieve universal connection, and work together with the up and down rotation of the second universal joint to make the device move more flexibly on the surface of the tank and reduce jamming.
[0015] 3. After the dual-output shaft motor in the inner cavity of the first frame of this utility model is started, the two sets of output ends respectively drive a set of active magnetic wheels to rotate, providing power for the movement of the device on the surface of the tank. The battery in the inner cavity of the support member at the top of the first frame provides power support for the operation of the dual-output shaft motor, electric push rod and other equipment. The helium remote detection module at the top of the support member is generally self-powered.

[0026] No need for inspectors to climb to heights, avoiding falls due to equipment aging or operational errors, thus improving operational safety. Employing a remote inspection method, the chassis connects the first frame 1 and the second frame 2 via a first universal joint. Adjustment components enable steering adjustment, better adapting to the curved surface changes of the tank's outer wall.
