Description

Technical Field

[0001] The utility model relates to the technical field of calibration equipment, and particularly relates to a sensor calibration device. Background Art

[0002] In the process of industrialized fish farming, in order to better monitor various indicators in the fish pond and achieve high-density and high-quality fish farming, temperature sensors, liquid level sensors, DO sensors, EC sensors, pH sensors, ammonia nitrogen sensors, etc. will be set in the fish pond to monitor indicators such as temperature, liquid level, dissolved oxygen, etc. in the fish pond. Since the sensors need to be calibrated after being used for a period of time to ensure the accuracy of the detected data of the sensors. For example, these sensors in the fish pond are calibrated about once every two weeks. The number of calibration steps, calibration requirements, and configured calibration solutions of these sensors are different. If traditional dedicated sensor calibration equipment is used, the staff needs to carry multiple calibration equipment and calibrate them one by one. The calibration time required for each sensor is 3-5 minutes. There are about 6 sensors in a fish pond, so it takes about 30 minutes to calibrate the sensors in a fish pond. A fish farm has dozens or hundreds of fish ponds, which will waste a lot of time calibrating the sensors in the fish ponds, and the work efficiency is low. Therefore, there is an urgent need for a calibration tool that can calibrate multiple different types of sensors at the same time. Summary of the Utility Model

[0003] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively provides a sensor calibration device, which can calibrate different sensors in batches and improve work efficiency.

A row of calibration solution storage grooves is arranged in each calibration area. A cleaning groove is arranged between adjacent calibration areas. A waste liquid tank, a calibration solution storage bottle and a cleaning solution storage bottle are arranged below the disc body. The cleaning groove and the calibration solution storage groove are both communicated with the waste liquid tank and the corresponding calibration solution storage bottle and cleaning solution storage bottle through liquid guide pipes. The disc body is also equipped with a drying device.

[0005] In the above solution: the number of calibration areas is an even number, the disc body is circular, the calibration areas are circumferentially and evenly distributed with the center of the disc body as the center, and the inner end of the cleaning groove matches the position of the innermost calibration solution storage groove, and the outer end of the cleaning groove matches the position of the outermost calibration solution storage groove.

[0006] In the above solution: the number and notch size of the calibration solution storage grooves in all calibration areas are the same, and the calibration solution storage grooves in the same calibration area are arranged adjacent to each other.

[0007] In the above solution: the number of the calibration areas is an even number, which can meet the situation of having more sensors but fewer calibration steps. A set of sensors can be arranged on both sides of the calibration disc at one time for calibration.

[0008] In the above solution: corresponding to each calibration liquid storage tank and cleaning tank at the bottom of the disc body, there is a connector for connecting the liquid guide pipe, which is convenient for connecting the liquid guide pipe.

[0009] In the above solution: there are multiple calibration liquid storage bottles, and each calibration liquid storage tank is separately communicated with a calibration liquid storage bottle, which can separately set storage bottles corresponding to each sensor and its calibration steps.

[0010] In the above solution: both the calibration liquid storage bottle and the cleaning liquid storage bottle are arranged in the storage box. Corresponding to each calibration liquid storage bottle and cleaning liquid storage bottle in the storage box, there are arc-shaped positioning clips, which are convenient for fixing the calibration liquid storage bottle and the cleaning liquid storage bottle and ensuring the external cleanliness.

[0011] In the above solution: the waste liquid tank is located below the storage box, and a through hole for the liquid guide pipe communicating with the waste liquid tank is arranged at the bottom of the storage box, which is convenient for wiring, keeps the external clean, and saves space.

[0012] In the above solution: the drying device is fixed above the disc body through a support rod, and the sensor can be dried by the drying device.

Moreover, the calibration liquid storage tank for each sensor is separately set, which can avoid being contaminated and affecting the calibration accuracy, and is convenient and fast.

And the calibration areas in this embodiment are even in number, which can make all the calibration areas be symmetrically arranged about the origin, and can meet the situation of more sensors but fewer calibration steps. A group of sensors can be set on both sides of the calibration disk for calibration at one time.

[0023] In each calibration area, a row of calibration liquid storage grooves 2 are sequentially arranged from the center of the circle to the outside, and a cleaning groove 3 is arranged between adjacent calibration areas. And the inner end of the cleaning groove 3 is matched with the position of the inner calibration liquid storage groove 2, and the outer end of the cleaning groove 3 is matched with the position of the outer calibration liquid storage groove 2. The number and the size of the openings of the calibration liquid storage grooves 2 in all calibration areas are the same, and the calibration liquid storage grooves 2 in the same calibration area are arranged adjacent to each other.

For the convenience of movement, the calibration liquid storage bottles 5a and the cleaning liquid storage bottles 5c are both arranged in the storage box 5, and arc-shaped positioning clips 5b are arranged in the storage box 5 corresponding to each calibration liquid storage bottle 5a and cleaning liquid storage bottle 5c, which is convenient for fixing the calibration liquid storage bottles 5a and the cleaning liquid storage bottles 5c and ensuring the external neatness. Only by moving the storage box 5 can the stability of the calibration liquid storage bottles 5a and the cleaning liquid storage bottles 5c be improved during the process of transferring to the next calibration location.

[0027] The waste liquid tank 6, the storage tank 5 and the tray body 1 are arranged in sequence from bottom to top.

[0029] During calibration, a batch of different types of sensors can be put into the cleaning tank 3 for cleaning. After cleaning, they are dried by the drying device 8 and then put into different calibration liquid storage tanks 2 in the first calibration area for the first step of calibration. During the calibration waiting period, the calibration liquid required for the next step of calibration can be prepared. After the first step of calibration is completed, they are put into the next cleaning tank 3 for cleaning. After cleaning, they are dried again and put into different calibration liquid storage tanks 2 in the second calibration area for the second step of calibration, and so on.
