Description

Technical Field

[0001] The utility model relates to the technical field of magnetic flux testing equipment, and particularly relates to a magnetic flux testing equipment applied to an ultrasonic heat meter. Background Art

[0002] In the process of detecting an ultrasonic heat meter, one of the detection processes requires placing the ultrasonic heat meter in a magnetic field, and then detecting the influence of the ultrasonic heat meter after experiencing the magnetic field, such as whether the ultrasonic heat meter can operate normally, so as to know the anti-magnetic interference performance of the ultrasonic heat meter.

[0003] In the traditional detection process, it is necessary to manually hold the ultrasonic heat meter and move it back and forth under the magnetic field, indicating that the ultrasonic heat meter has passed through the magnetic field interference, and then detecting whether the ultrasonic heat meter after being interfered by the magnetic field can be used normally in the next process.

[0004] Since this traditional detection method uses manual detection, there is uncertainty, and it is difficult to form a unified standard action during the detection process, which further leads to uncertainty in the subsequent detection results.

[0005] Therefore, improvements need to be made in this regard. Summary of the Utility Model

[0028] As Figure 1-8As shown in the figure, a magnetic flux testing device applied to an ultrasonic heat meter is provided, including: a testing machine table 1, on which a driving button 2 and a display screen 3 are provided; a first bracket 4, which is installed on the upper part of the testing machine table 1, and a pair of parallel slide rails 5 are provided on the first bracket 4; a tray 6, which is slidably arranged on the slide rails 5, and the tray 6 is provided with a mounting position 7 for fixing the ultrasonic heat meter 21; a second bracket 8, which is installed above the first bracket 4; a code scanning device 9, which is installed on the second bracket 8, and the code scanning device 9 is used to scan and record the model of the ultrasonic heat meter 21 and upload it to the host computer; a motor 10, which is arranged on the second bracket 8, the output end of the motor 10 faces the tray 6, and a magnetic fan blade 11 is provided on the output end of the motor 10, and the magnetic fan blade 11 is placed above the position to be tested of the ultrasonic heat meter 21; the motor 10 drives the magnetic fan blade 11 to rotate, generating an alternating magnetic field interference at the position to be tested of the ultrasonic heat meter 21 on the tray 6.

[0029] In view of the technical problems recorded in the background art, a magnetic flux testing device applied to the ultrasonic heat meter 21 is provided. Its main purpose is to standardize the magnetic flux testing process of the ultrasonic heat meter 21 by designing the testing device, and adopt a unified mechanical process for testing. The testing process is standardized to ensure the detection of the ultrasonic heat meter 21 after magnetic field interference in the subsequent process, and accurately judge the magnetic field anti-interference ability of the ultrasonic heat meter 21.

[0030] The driving button 2 of the testing machine table 1 is the switch for driving the device to operate, and the display screen 3 is used to display or adjust information such as the operating parameters of the device.

[0031] The specific testing process is as follows: Manually place the ultrasonic heat meter 21 to be tested on the mounting position of the tray 6, manually push the tray 6 along the guide rail to the specified position, then press the driving switch, the motor 10 drives the magnetic fan blade 11 to rotate. The magnetic fan blade 11 is a fan blade structure made of a magnet 14. The motor 10 is set to drive the magnetic fan blade 11 to rotate within a specified time, so as to generate magnetic field interference at the position to be tested of the ultrasonic heat meter 21. After the magnetic field interference ends, manually remove the tested ultrasonic heat meter 21 from the tray 6, thus completing the testing operation.

[0032] As Figure 4-5 As shown in the figure, the first bracket 4 is provided with a limit plate 12, the limit plate 12 is placed at the rear of the slide rail 5, and the tray 6 is provided with a position sensor 13, and the position sensor 13 is used to detect the distance from the limit plate 12.

[0033] To facilitate the manual pushing of the tray 6 to a specified position, a limiting plate 12 is provided on the first bracket 4. The position where the limiting plate 12 is set is the position where the tray 6 stops moving. For this purpose, the limiting plate 12 is combined with the in-place sensor 13. During use, the tray 6 is manually pushed to move on the guide rail. When the in-place sensor 13 on the tray 6 detects the limiting plate 12, it means that the tray 6 has moved to the specified position.

[0034] Specifically, a magnet 14 for adsorbing to the limiting plate 12 is provided at the rear of the tray 6.

[0035] In order to prevent the tray 6 from moving during the test, a magnet 14 is provided on the tray 6. The tray 6 and the limiting plate 12 are magnetically adsorbed, thereby avoiding the movement of the tray 6 during the test and causing magnetic field interference to non-test positions.

[0036] Specifically, the installation position 7 includes an opening 15 for placing the ultrasonic heat meter 21, a left limiting portion 16 provided on the left side of the opening 15, and a right limiting portion 17 provided on the right side of the opening 15.

[0037] The above installation position 7 is an installation position 7 set by copying the ultrasonic heat meter 21 to be tested. The opening 15, the left limiting portion 16, and the right limiting portion 17 are used to form the installation and fixation of the ultrasonic heat meter 21.

[0038] Specifically, the magnetic fan blade 11 includes a first blade, a second blade, and a third blade that are circumferentially and arrayedly distributed.

[0039] Among them, in the present utility model, the magnetic fan blade 11 has at least one blade or more. In order to improve the test efficiency, multiple blades can be set. In this embodiment, preferably, the magnetic fan blade 11 is selected to have three blades.

[0040] Reference Figure 6-7 As shown, an induction sheet 18 is installed on any blade of the magnetic fan blade 11. A zero position sensor 19 is provided on one side of the induction sheet 18. The zero position sensor 19 is used to locate the starting point of the rotation of the motor 10.

[0041] To facilitate the unified magnetic field interference on the ultrasonic heat meter 21, a zero position sensor 19 is provided to determine the starting point of the motor 10. Thus, according to the setting, the number of turns of the motor 10 rotates to form a magnetic field interference on the ultrasonic heat meter 21.

[0042] Furthermore, it includes a cover body 20 provided on the test machine table 1. The cover body 20 is used to cover the mechanical components.

[0043] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
