Description

Technical Field

[0001] The utility model relates to the technical field of thermometers, and more specifically, to an extended and redirected device for a photodetector. Background Art

[0002] A high-temperature infrared thermometer is a portable hand-held thermometer applicable to various industrial high-temperature environments. In the environment of metal refining and smelting, accurate measurements required can be carried out at any time in high-temperature environments and with a high distance-to-light-spot ratio.

[0003] Principle of the infrared thermometer: The infrared thermometer consists of an optical system, a photodetector, a signal amplifier, signal processing, display output, and other parts. The radiation lines of the object to be measured and the feedback source are modulated by a modulator and then input into the infrared detector. The difference between the two signals is amplified by an inverse amplifier and used to control the temperature of the feedback source, so that the spectral radiation luminance of the feedback source is the same as that of the object. The display indicates the brightness temperature of the object to be measured.

[0004] When measuring with a high-temperature infrared thermometer, it is necessary to directly align point-to-point with the part of the object to be measured for measurement, and it cannot be measured when there are obstacles blocking. When measuring at a relatively short distance, the high-temperature infrared thermometer is easily affected by high-temperature radiation and may malfunction or be damaged. Content of the Utility Model

[0005] The purpose of the utility model is to provide an extended and redirected device for a photodetector, which can redirect and extend the photodetector to facilitate meeting different measurement requirements.

[0006] The embodiments of the utility model are realized through the following technical solutions:

[0007] An extended and redirected device for a photodetector includes a high-temperature infrared thermometer, an extension tube, and a probe. The extension tube is detachably connected to the high-temperature infrared thermometer, the probe is rotatably connected to the extension tube, and a photodetector is arranged on the probe.

[0008] Further, the extension tube includes a first branch pipe and a second branch pipe, and the first branch pipe and the second branch pipe are slidably connected.

[0009] Further, a cavity is formed inside the first branch pipe, and an electric push rod is installed in the cavity. The driving end of the electric push rod is connected to the second branch pipe.

[0010] Further, a rotating shaft is arranged at one end of the extension tube, a rotating seat is installed on the rotating shaft, a connecting seat is arranged on the probe, and the connecting seat is rotatably connected to the rotating seat.

[0011] Further, the probe includes a housing, the photodetector is installed in the housing, and the connecting seat is installed outside the housing.

The extension tube is connected to the measuring portion. A display screen and buttons are provided at the rear end of the measuring portion, and a groove is provided at the front end of the handle portion for accommodating fingers.

[0013] Further, a sweat-absorbing pad is provided at the rear end of the handle portion.

[0014] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:

[0015] In the present utility model, the rotatable connection between the probe and the extension tube can change the original measurement method that can only be a straight line point-to-point. When in use, the probe is rotated to change the angle of the probe to achieve turning measurement, which helps to expand the measurement range. By connecting the high-temperature infrared thermometer and the probe through the extension tube, the measurement distance between the handheld high-temperature infrared thermometer and the high-temperature object can be extended, reducing the failure rate or damage rate caused by the influence of short-distance high-temperature radiation. In addition, the cooperation of the high-temperature infrared thermometer, the extension tube and the probe can, without changing other performances of the high-temperature infrared thermometer, bypass obstacles and approach the position to be measured directly for temperature measurement under the condition of obstacle occlusion.

The extension tube 2 is detachably connected to the high-temperature infrared thermometer 1, the probe 3 is rotatably connected to the extension tube 2, and a photodetector 32 is provided on the probe 3.

[0028] The rotatable connection between the probe 3 and the extension tube 2 can change the original linear point-to-point measurement method. During use, the angle of the probe 3 is rotated to achieve turning measurement, which helps to expand the measurement range. By connecting the high-temperature infrared thermometer 1 and the probe 3 through the extension tube 2, the measurement distance between the handheld high-temperature infrared thermometer 1 and the high-temperature object can be extended, reducing the failure rate or damage rate caused by the influence of short-distance high-temperature radiation. In addition, the cooperation of the high-temperature infrared thermometer 1, the extension tube 2, and the probe 3 can, without changing other performance of the high-temperature infrared thermometer 1, bypass obstacles and approach the position to be measured directly for temperature measurement in the case of obstacles. The handheld high-temperature infrared thermometer 1 does not need to be directly aligned linearly with the measured part, making it flexible and convenient to use.

At the same time, the probe 3 can also be rotated to make the connecting seat 33 rotate around the rotating seat 24, thereby further changing the longitudinal measurement angle of the photodetector 32 on the probe 3.

[0033] In this embodiment, the probe 3 includes a housing 31, the photodetector 32 is installed in the housing 31, and the connecting seat 33 is installed outside the housing 31.
