Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for an instrument calibration device: including: a base 1, a calibration table 2 arranged on the upper surface of the base 1, and an instrument calibration equipment 3 embedded in the upper surface of the calibration table 2. Fixing plates 42 are symmetrically arranged on the upper surface of the calibration table 2. A lifting plate 41 penetrates through the upper surface of the fixing plate 42. A pressing plate 4 is connected to the upper surface of the lifting plate 41. Positioning rods 43 are symmetrically arranged on the front surface of the pressing plate 4. A wire clamping ring 431 is connected to the lower end of the positioning rod 43 in front of the instrument calibration equipment 3. This setting uses the pressing plate 4 to press and position the instrument calibration equipment 3, and the wire clamping ring 431 can clamp the wires for instrument calibration by the instrument calibration equipment 3 to ensure its stability and prevent it from falling off and affecting the use.

[0023] An installation groove is provided on the front surface of the base 1. A storage box 51 is slidably installed inside the installation groove. A pulling plate 5 is connected to the front surface of the storage box 51. A storage groove 53 is provided inside the storage box 51. This setting uses the storage groove 53 provided inside the storage box 51 to conveniently place the wires for calibration, so as to facilitate their quick access.

[0024] Such as Figure 2As shown in the figure, a limiting plate 411 is connected inside the lifting plate 41 within the fixed plate 42. Springs 421 are symmetrically arranged inside the fixed plate 42. The upper ends of the springs 421 are fixed to the lower surface of the limiting plate 411, and the lower ends of the springs 421 are fixed inside the fixed plate 42. This setting utilizes the pulling of the pressing plate 4 to cause the springs 421 to deform, and after release, the springs 421 restore their deformation to make the pressing plate 4 move downward to press the instrument calibration device 3, ensuring the stability of the instrument calibration device 3.

[0025] As Figure 2 shown in the figure, the pressing plate 4 and the lifting plate 41 are arranged in a "U" shape. Three positioning rods 43 are arranged in an "L" shape on the front surface of the pressing plate 4. Positioning holes are symmetrically formed on the front surface of the pressing plate 4. The rear ends of the positioning rods 43 are embedded inside the positioning holes. This setting enables the installation of the positioning rods 43 by embedding the positioning rods 43 into the positioning holes.

[0026] As Figure 1 and Figure 3 shown in the figure, a placement groove 21 is formed on the upper surface of the calibration table 2. The lower surface of the instrument calibration device 3 is embedded inside the placement groove 21. This setting facilitates the positioning and installation of the instrument calibration device 3 by using the placement groove 21.

[0027] As Figure 3 and Figure 4 shown in the figure, two partition plates 52 are symmetrically arranged inside the storage groove 53. Positioning pins 54 are symmetrically arranged on the rear surface of the storage box 51. Limiting holes that are engaged with the positioning pins 54 are formed inside the base 1. This setting enables the positioning of the storage box 51 by embedding the positioning pins 54 into the limiting holes. Through the storage box 51, it is convenient to place the wire into the storage groove 53 for easy access.

[0028] The working principle of the present utility model is as follows: When the present utility model's instrument calibration device is in use, first, pulling the pressing plate 4 upward will cause the lifting plate 41 to move inside the fixed plate 42, thereby causing the springs 421 inside the fixed plate 42 to deform. At this time, the instrument calibration device 3 can be installed inside the placement groove 21 and the pressing plate 4 can be released. Then, the springs 421 will restore their deformation and the pressing plate 4 will be used to position and press the instrument calibration device 3, facilitating the calibration work of the thermal power plant instruments. During calibration, the pull plate 5 can be pulled outward to extract the storage box 51 from inside the base 1, and the wire inside the storage groove 53 can be taken out for use. When in use, the wire can be inserted into the wire clamping ring 431 connected to the lower end of the positioning rod 43 to fix the wire and prevent it from falling off and affecting the calibration work.

[0029] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
