Description

Technical Field

[0001] The utility model relates to the technical field of sensor calibration devices, in particular to a static charge sensor calibration device. Background Art

[0002] Electrostatic monitoring technology can be used to monitor abrasive particles in the lubrication oil circuit of large equipment, and the health status of lubricated parts can be understood based on the monitored abrasive particle information. In existing electrostatic sensor calibration devices, sensors are fixed on brackets and cannot be adjusted, and the positional relationship between the particle trajectory and the sensor center axis cannot be measured, so the spatial characteristics of the sensor can only be studied qualitatively.

[0003] In the prior art, a Chinese patent document with the publication number CN104215557B is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: an electrostatic sensor calibration device is a device for calibrating an electrostatic sensor for online monitoring of wear particles in the lubrication oil circuit of large equipment. The device consists of an oil droplet charging device, a sensor support and positioning device, and an oil droplet charge measuring device.

[0004] In order to solve the problem that the sensors are fixed on the bracket and cannot be adjusted, let alone measure the positional relationship between the particle trajectory and the central axis of the sensor, the existing technology adopts a method consisting of an oil droplet charging device, a sensor support and positioning device, and an oil droplet charge measuring device. However, the device is easily affected by the outside world when in use, and is prone to dust accumulation when stored, which leads to the problem that the device has no protective structure and affects its use. Utility Model Content

[0005] The purpose of the utility model is to provide a calibration device for an electrostatic charge sensor to solve the problems raised in the above-mentioned background technology.

[0008] The protection component comprises a mounting ring, a folding transparent cover and a connecting ring.

[0009] A further improvement of the technical solution of the utility model is that: the lower insulating platform includes a lower main board, a lifting rod is fixedly installed on the surface of the lower main board, an adjusting nut is movably installed on the surface of the lifting rod, and a Faraday cup is fixedly installed in the middle of the surface of the lower main board.

By installing adhesive blocks on the upper main board and the middle main board, the folded transparent cover can be moved up when internal protection is required, and the adhesive block contacts the connecting ring for adhesion, so that fixation can be achieved, preventing it from falling off during the protection process and affecting the protection effect.

[0013] A further improvement of the technical solution of the utility model is that: the mounting ring is fixedly mounted on the surface of the lower main board, the folding transparent cover is fixedly mounted on the surface of the mounting ring, and the connecting ring is fixedly mounted on the top surface of the folding transparent cover. By arranging a protective component, when in use or storage, the folding transparent cover can be moved up by the connecting ring and then fixed with the adhesive block, so as to protect the upper insulating platform and the middle insulating platform and prevent dust and the like from affecting the safety of the device.

[0014] A further improvement of the technical solution of the utility model is that: the adjusting nuts are provided in multiple groups and are all arranged on the surfaces of the upper main board and the middle main board, and the adjusting rods and the limit blocks are provided in four groups.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides an electrostatic charge sensor calibration device. By setting a limit component, when the electrostatic charge sensor calibration device is used, a folded transparent cover is moved down and a limit block is rotated on an adjustment rod, so that a clamping connection ring can be used to limit the cover, thereby facilitating opening of the device for operation.

[0017] The utility model provides an electrostatic charge sensor calibration device. By installing adhesive blocks on an upper main board and a middle main board, a folded transparent cover can be moved upward when internal protection is required. The adhesive blocks contact a connecting ring for adhesion, thereby achieving fixation and preventing the cover from falling off during the protection process and affecting the protection effect.

By arranging a protection component, when in use or storage, the transparent cover can be folded up by a connecting ring and then fixed with an adhesive block, so that the upper insulating platform and the middle insulating platform can be protected to prevent dust and the like from affecting the safety of the device.
