Description
Technical Field
The utility model relates to the technical field of liquid temperature calibration, in particular to an auxiliary device for liquid bath calibration.
Background
Liquid baths are common temperature heating devices in laboratories and are generally calibrated using media such as water, alcohol, silicone oil, etc. using a standard platinum resistance thermometer. The platinum resistance thermometer has slow stability time, needs to be suspended in liquid, and needs to perform multi-point measurement on the same plane in the liquid according to the regulation. In actual work, the handheld instrument cannot ensure the consistency of the measurement position and the depth, and the operator is easily fatigued by keeping one posture for a long time. In addition, when the temperature is high, high temperature or water vapor may present a safety hazard to the hands.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provides an auxiliary device for liquid bath calibration, which comprises a platinum resistance thermometer and a substrate, wherein the substrate is arranged above liquid, the top of the substrate is provided with a top sliding chute, and the side surface of the substrate is provided with a side sliding chute; the sliding block is arranged on the top of the base plate and can move along the sliding groove on the top of the base plate; the clamp is connected with the sliding block; the fixed baffle plate is arranged in the substrate side sliding groove and can move along the substrate side sliding groove.
Furthermore, the clamp is provided with an adjusting knob.
Compared with the prior art, the utility model has the advantages that:
1. the platinum resistance thermometer can be fixed in a working area, a standard device does not need to be held by a person, the horizontal depth of a measuring point is guaranteed to be consistent, and potential safety hazards are avoided;
2. the movement of the platinum resistance thermometer on the rectangular horizontal plane of the liquid bath equipment can be realized.

Detailed Description
The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1 and 2, the utility model is an auxiliary device for liquid bath calibration, comprising a platinum resistance thermometer, a substrate, a slider, a clamp and a fixed baffle, wherein the substrate is arranged above liquid, a top sliding groove is arranged at the top of the substrate, and a side sliding groove is arranged at the side surface of the substrate; the sliding block is arranged on the top of the substrate and can move along the sliding groove on the top of the substrate; the clamp is connected with the sliding block; the fixed baffle is arranged in the side chute of the substrate and can move along the side chute of the substrate.
In a preferred embodiment, the clamp of the present invention is further provided with an adjusting knob.
The structure and the function of the components are as follows:
1. adjusting a knob: the angle and the force of the clamp are changed by rotating so as to meet the requirements of different platinum resistance thermometers;
2. a clamp: the platinum resistance thermometer is used for fixing the platinum resistance thermometer, and the angle can be changed by adjusting a knob;
3. a top chute: the guide device is used for guiding the moving track of the sliding block to enable the sliding block to move longitudinally in a horizontal plane;
4. substrate: means for securing the entire apparatus so as to span over the working area of the liquid bath apparatus;
5. a slide block: the fixture is used for fixing the fixture and realizing the longitudinal movement of the platinum resistance thermometer on the horizontal plane;
6. fixing a baffle: the substrate fixing device is used for fixing the substrate above a working area of the liquid bath equipment and limiting the substrate to move in the longitudinal direction;
side chute: the guide device is used for guiding the moving track of the fixed baffle plate, so that the fixed baffle plate can be adapted to working areas with different widths.
The working process of the utility model is as follows:
in calibration, the device is spanned over a liquid bath working area with the substrate longitudinally parallel to the working area. The fixing baffle is adjusted to clamp the front and the rear sides of the equipment, so that the device is fixed. The platinum resistance thermometer is clamped by a clamp and adjusted to a proper height, and the reading can be carried out after the reading is stable. When the position of the clamp on the horizontal plane of the whole working area needs to be adjusted, the clamp can be moved to shift to adjust in the horizontal direction, and the slide block is moved to adjust in the vertical direction.
In one embodiment, the water bath enclosure is removed, the device is stretched longitudinally over the liquid medium, and the water bath housing is clamped with a retaining baffle to stabilize the device. The platinum resistance thermometer was extended into a fixed position in the liquid and the knob was adjusted to be grasped by the clamp. The water bath was started and after it reached the set temperature and stabilized, the reading of the platinum resistance thermometer was read. Then the temperature of other positions of the liquid medium needs to be measured. The device is moved laterally along the rectangular area and then the slide is moved so that the platinum resistance thermometer is positioned at another location on the surface and the reading is again taken after stabilization. And executing the step for multiple times, and calculating according to the measured value to finish the calibration.
