[0035] Embodiment 1

[0036] The liquid level sensor detection device provided in this application can be used to calibrate the accuracy of the bubble type liquid level sensor. Figures 1 to 4 As shown, the liquid level sensor detection device provided by the present application includes a detection air pipe 101 and a liquid storage container 102. The liquid storage container 102 is used to load a liquid medium 103, and the liquid medium 103 can be water, or the same as the medium loaded in each cabin 116 on site. The liquid storage container 102 is in a long strip shape and is placed vertically, which can reduce the volume of the device while ensuring that the loaded liquid medium 103 has a certain depth. The liquid storage container 102 is provided with a scale marking the liquid level height so that the operator can read the liquid level height of the liquid medium 103.

[0037] One end of the detection air pipe 101 is an air inlet end, and the air inlet end is used to communicate with the air outlet of the liquid level sensor 106. An opening is provided at the upper end of the liquid storage container 102. The other end of the detection air pipe 101 is an air outlet end, and the air outlet end is placed in the liquid storage container 102 from the opening and extends below the liquid surface of the liquid medium 103. After the liquid level telemetry system is powered on and debugged, the liquid level sensor 106 exhausts air into the liquid medium 103 through the detection air pipe 101 to generate bubbles. By measuring the rising speed or position of the bubbles in the liquid medium 103, the measured liquid level height can be read on the liquid level telemetry system. By comparing the measured liquid level height with the liquid level height read by the operator, it can be verified whether the accuracy of the liquid level sensor 106 is accurate and whether there is a leak in the pipeline. In view of the different liquid level heights in different chambers 116 in actual applications, when measuring the accuracy of the liquid level sensor 106, the liquid level height can be adjusted by changing the amount of liquid medium 103 to perform multiple tests on the liquid level sensor 106 under multiple test conditions.

[0038] It should be noted that the measured liquid level height is the distance between the air outlet end and the liquid surface. When the operator reads the liquid level height, it is necessary to read the scale of the air outlet end and the scale of the liquid surface, and convert the difference between the two, and then compare the difference with the measured liquid level height.

[0039] The liquid level sensor detection device provided in the present application can detect the accuracy of the liquid level sensor 106 by setting up a detection air pipe 101 and a liquid storage container 102. There is no need to add too much liquid medium 103 into the liquid storage container 102 to achieve a liquid level height that meets the detection requirements. The device is small in size and easy to carry, which can shorten the debugging period.

[0040] In an optional scheme of this embodiment, the detection air pipe 101 includes a connecting flange 104 and an air duct 105; the connecting flange 104 is used to be detachably connected to the air outlet of the liquid level sensor 106; one end of the air duct 105 is connected to the connecting flange 104, and the other end of the air duct 105 is the air outlet end.

[0041] In this embodiment, if Figure 5 As shown, a measuring air pipe 107 is installed in the chamber 116 of the liquid level to be measured, and the measuring air pipe 107 is detachably connected to the air outlet of the liquid level sensor 106 through a flange. When the liquid level sensor 106 is tested, the liquid level sensor 106 and the measuring air pipe 107 can be disassembled, and the connecting flange 104 can be connected to the air outlet of the liquid level sensor 106 to verify the liquid level sensor 106.

[0042] In the optional scheme of this embodiment, the liquid storage container 102 includes a liquid storage tube 108 and a connection switch 109. The liquid storage tube 108 is used to load the liquid medium 103, and the liquid storage tube 108 is provided with a scale indicating the liquid level height. The liquid storage tube 108 can be a transparent UPVC tube, which has excellent characteristics such as corrosion resistance, aging resistance, environmental protection, light weight and easy installation and processing. The liquid storage tube 108 can specifically select a UPVC tube with a diameter of 110mm and a thickness of 5mm, so that the operator can more easily observe the liquid level height of the liquid medium 103 from the outside of the tube. And the liquid storage tube 108 of this specification can control the overall weight and ensure the internal and external compressive strength of the liquid storage container 102. At the same time, the diameter size can avoid the bubble fluctuation generated by the liquid level telemetry working air in the liquid storage container 102 from affecting the test value.

[0043] like Figure 2As shown, during detection, the liquid storage tube 108 is placed vertically so that the length direction of the liquid storage tube 108 is the depth direction of the liquid medium 103, thereby making the detection range larger. The end of the detection air pipe 101 is placed in the liquid storage tube 108 from the top pipe opening of the liquid storage tube 108. The connection switch 109 is installed at the bottom pipe opening of the liquid storage tube 108, and the connection switch 109 can be opened or closed to block or open the bottom pipe opening. During detection, the connection switch 109 can be turned off to block the bottom pipe opening so that the liquid level height of the liquid medium 103 in the liquid storage tube 108 remains unchanged. When adjusting the liquid level height of the liquid medium 103 in the liquid storage tube 108, the connection switch 109 can be opened to open the bottom pipe opening, and the liquid medium 103 can be supplied or discharged to the detection air pipe 101, thereby raising or lowering the height of the liquid medium 103 in the detection air pipe 101, so as to realize multiple detections of the liquid level sensor 106 under multiple test conditions.

[0044] In an optional solution of this embodiment, specifically, the connecting switch 109 includes a mounting shell 110 and a valve 111; a connecting port is provided at the top of the mounting shell 110, and the connecting port is connected to the bottom pipe port; a mounting port is provided at the side of the mounting shell 110, and the valve 111 is installed at the mounting port.

[0045] Optionally, the connection switch 109 further includes a positioning base 112 installed at the bottom of the installation shell 110 .

[0046] In this embodiment, the mounting shell 110 is specifically a three-way pipe fitting, the three-way pipe fitting is a straight tee, and the main pipe and the branch pipe of the three-way pipe fitting are vertical. Figures 1 to 4 As shown, the main pipe of the three-way pipe fitting is placed vertically, the upper end of the main pipe can be connected and fixed to the liquid storage pipe 108 by PVC glue, and the lower end of the main pipe is installed with a positioning base 112, which is specifically a PVC cap. On the one hand, the positioning base 112 is used to block the lower end of the pipe; on the other hand, the positioning base 112 can be provided with a larger support surface, so that when the liquid storage container 102 is placed vertically, the liquid storage container 102 can be more stable and not easy to tip over.

[0047] Since the lower end of the main pipe of the three-way pipe fitting is blocked, the branch pipe of the three-way pipe fitting located at the side forms a circulation channel for the liquid medium 103. A valve 111 is installed in the branch pipe of the three-way pipe fitting. The valve 111 is specifically a ball valve and can open or close the circulation channel. This structure changes the flow direction of the liquid medium 103 to guide the liquid medium 103 between the liquid storage container 102 and the supply or discharge point. And the circulation channel located at the side does not affect the placement of the liquid storage container 102, so that the device is more stable.

[0048] In an optional solution of this embodiment, the connecting switch 109 also includes a guide tube 113, which is a hose, and one end of the guide tube 113 is connected to the conducting port of the valve 111, and the other end of the guide tube 113 is connected to a water pump or a drain port to supply or discharge the liquid medium 103 to the liquid storage tube 108, so as to facilitate the filling and discharge of the liquid medium 103.

[0049] In the optional solution of this embodiment, Figure 3 and Figure 4 As shown, the liquid storage tube 108 includes a plurality of connecting tubes 114 , and along the length direction of the liquid storage tube 108 , the plurality of connecting tubes 114 are detachably connected in sequence.

[0050] Optionally, the liquid storage tube 108 further includes a pipe connector 115 , and a pipe connector 115 is installed between two adjacent connecting tubes 114 .

[0051] In this embodiment, when manufacturing the liquid storage tube 108, the longer UVPC transparent pipe can be first divided into several 1.5-meter-long connecting tubes 114, and then the multiple connecting tubes 114 are connected in sequence in the vertical direction. The connecting tube 114 at the bottom is bonded and fixed to the mounting shell 110 with PVC glue, and two adjacent connecting tubes 114 can be connected by a flexible joint, which is convenient for disassembling, shortening or extending the liquid storage tube 108. The length of the liquid storage tube 108 can be set according to actual conditions to cope with the test conditions of the cabin 116 at different heights; the shorter connecting tube 114 is convenient for entering the narrow space near the cabin 116, and is assembled on site to a suitable length, which is convenient for transportation and carrying.

[0052] Embodiment 2

[0053] The liquid level sensor detection device in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0054] In an optional solution of this embodiment, a counterweight is provided at the outlet end of the detection air pipe 101, and the gravity of the counterweight can make the end of the detection air pipe 101 located at the bottom of the liquid storage container 102. At this time, the scale value of the liquid level height read by the operator is the actual depth of the liquid medium 103, and the value can be compared with the liquid level height measured by the liquid level sensor 106, which is more convenient for detection.

[0055] The specific process of testing the liquid level sensor 106 is as follows: after the liquid level telemetry system is turned on, different simulated liquid level heights can be used according to the installation form of the liquid level sensor 106 in each cabin 116 on site and the different medium densities, and the corresponding measured density conversion value can be set in the system to perform multi-point simulation tests in each cabin 116 to ensure the accuracy of the simulation test. During the test, the test air pipe 101 is placed at the bottom of the liquid storage container 102. Water is added to the liquid storage container 102, and it is filled three times respectively. By comparing the different liquid level scale values ​​on the liquid storage container 102 with the reading values ​​on the liquid level telemetry system, the purpose of verifying whether the sensor accuracy is accurate and whether there is air leakage in the air pipeline can be achieved.
