Description

Technical Field

[0001] This utility model relates to the technical field of liquid level gauge calibration, and in particular to a liquid level measuring instrument calibration device. Background Technology

[0002] The level of a liquid medium in a container is called the liquid level, and the instrument used to measure the liquid level is called a level gauge. Level gauges are a type of level instrument, and there are various types, including tuning fork vibrating type, magnetic levitation type, pressure type, ultrasonic type, sonar type, magnetic float type, and radar type. Level gauges require multiple calibrations throughout their service life, necessitating standard instruments and matching calibration devices to meet technical requirements. Existing technology publication number CN220454671U proposes a level gauge calibration device, which includes a base plate with a base on top. A detection water tank is fixedly installed on the top of the base, and a scale is provided on the detection water tank. Inlet and outlet pipes are installed on both sides of the detection water tank, a level is installed on the front of the detection water tank, and a pressure sensor and a temperature sensor are installed on one side of the detection water tank. Four symmetrically arranged support rods are slidably connected to the base, and the support rods are movably connected to the base plate. However, in use, the liquid level cannot be observed immediately, requiring the use of other auxiliary tools for detection and manual control of the liquid level, making operation extremely inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a liquid level measuring instrument calibration device that can install and place the liquid level measuring instrument, avoid shaking during detection, and is simple to operate and convenient to use.

[0004] This utility model discloses a liquid level measuring instrument calibration device, comprising a water tank, a detection box, a control processor, a conveying component, a fixing component, a supporting component, and a support component. The detection box is mounted on the top of the water tank, and its bottom is connected to the interior of the water tank. The control processor is mounted on the right side of the top of the water tank. A conveying component is installed between the water tank and the detection box. A fixing component is mounted on the top of the detection box. A supporting component is mounted at the lower end of the detection box, and a support component is mounted at the bottom of the water tank. The support component supports the bottom of the water tank to ensure it is level during testing. The fixing component holds the liquid level measuring instrument in place, and the supporting component supports the bottom of the instrument to prevent shaking during testing. The conveying component quantitatively inputs liquid into the detection box to calibrate the liquid level measuring instrument. The device is simple to operate and convenient to use.

[0005] Preferably, the fixing components include two sets of uprights, two mounting seats, two lead screws, two connecting plates, two sets of support rods, two adjusting wheels, two clamping plates, and two lifting plates. The top of each support rod has a circular hole. Uprights are symmetrically mounted on the top of the detection box about the circular holes. Mounting seats are movably mounted on the uprights. Lead screws are screwed into the center of each mounting seat. Clamping plates are rotatably mounted at the ends of the two lead screws that are close to each other.

Adjusting wheels are mounted on the outer ends of the lead screws. The bottom of the clamping plates contains the interior of the lifting plates. Rotating the adjusting wheels pushes the lead screws to move on the mounting seats, causing the two clamping plates and the lifting plates to move, which in turn causes the support rods to slide on the mounting seats, enhancing connection strength and ensuring stability. The movable connection between the uprights and the mounting seats allows the liquid level measuring instrument to have a certain range of motion.

[0006] Preferably, the supporting component includes an extension plate, a threaded rod, a servo motor, a support rod, a guide slider, and a support seat.

A support seat is installed at the front end of the support rod. Both the support seat and the support rod have round holes. When the servo motor is started, it drives the support rod to move within the water tank. When the support rod moves, it drives the guide slider to move within the guide groove, guiding and limiting it. The support rod drives the support seat to move, supporting the bottom of the liquid level measuring instrument and preventing shaking during detection.

[0007] Preferably, the delivery components include a metering pump, a suction pipe, and a delivery pipe. The metering pump is installed at the top left of the water tank. The input end of the metering pump is connected to the suction pipe, which extends into the bottom of the water tank.

When the metering pump is started, liquid is drawn through the suction pipe and quantitatively delivered into the detection chamber through the delivery pipe. The liquid level is detected by a liquid level measuring instrument, and the liquid level scale inside the water tank is observed at the scale line. The control processor calculates the liquid level in the detection chamber based on the delivery volume of the metering pump and the capacity of the detection chamber, thereby realizing multi-group measurement calibration of the liquid level measuring instrument.

[0008] Preferably, it also includes a solenoid valve, a liquid inlet pipe, and a liquid outlet pipe. A solenoid valve is installed at the output end of the bottom of the test chamber, and a liquid inlet pipe is installed on the right side of the top of the water tank. A liquid outlet pipe is connected to the lower part of the right side wall of the liquid inlet pipe, and a valve is installed on the liquid outlet pipe.

Simultaneously, the first level 28 and the second level 29 detect the horizontal position of the water tank 1, assisting in adjusting the water tank 1 to a horizontal state. The liquid level measuring instrument passes through the round hole into the detection chamber 2. Rotating the adjusting wheel 15 pushes the lead screw 12 to move on the mounting base 11, causing the two clamping plates 16 and the lifting plate 17 to clamp and fix the upper part of the liquid level measuring instrument.
