[0002] In the factory water treatment system, the water storage tank is one of the important devices, which is used to store the treated purified water and provide water source for production. At present, some factory water storage tanks are semi-closed water storage tanks, which are only equipped with a breathing valve and a top manhole, lacking an effective liquid level indication or display device. In this case, the staff often discovers after the water storage tank is short of water, which seriously affects the production progress and brings unnecessary losses to the factory.

[0003] The existing liquid level monitoring methods are either costly and not suitable for small and medium-sized factories; or have a single function, can only achieve simple liquid level display, cannot be linked with the water treatment system for control, and cannot fundamentally solve the problem of lagging water shortage warning of the water storage tank. Therefore, there is a need to provide an on-line water level detection device to solve the above technical problems. Content of the Utility Model

[0004] To solve the problems raised in the above background technique. The utility model provides an on-line water level detection device, which has the characteristics of being able to monitor the liquid level of the water storage tank in real time, and realizing linkage control and alarm functions with the water treatment system according to different liquid level thresholds, so as to avoid the influence of water shortage in the water storage tank on production.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an on-line water level detection device, including a water storage tank, a reserved hole is provided at the bottom of one side of the water storage tank, a four-way joint is fixedly connected in the reserved hole, and the other interfaces of the four-way joint are respectively connected with a pressure sensor, a transparent liquid level tube and a drain pipe. The pressure sensor is connected with a columnar display instrument. A fixed seat is fixedly connected to the outer side of the upper end of the transparent liquid level tube, and the fixed seat is fixedly connected to the outer wall of the top of the water storage tank.

[0006] Preferably, stop valves are provided between the pressure sensor, the transparent liquid level tube, the drain pipe and the four-way joint.

[0007] Preferably, the columnar display instrument includes an LED light column for dynamically displaying the proportion of the liquid level occupying the full scale;

[0008] a digital tube for displaying the liquid level percentage and the tonnage value in the water storage tank;

[0009] a buzzer for giving an alarm when the liquid level is abnormal;

[0010] A control module is arranged in the control box, which is used to receive the liquid level signal of the pressure sensor and output corresponding control signals to the water treatment system and the buzzer according to the preset threshold.

[0011] Preferably, the control module is a PLC module or a relay module, which supports manual adjustment of preset threshold parameters.

[0012] Preferably, the control module presets three thresholds:

[0013] When the liquid level is below 60%, the low liquid level trigger signal is linked with the water treatment system to start the water purification equipment.

[0014] When the liquid level is above 90%, the high liquid level signal is linked with the water treatment system to stop the water purification equipment.

[0015] When the liquid level is below 40% or the tonnage in the tank is below 8 tons, the low liquid level alarm signal triggers the buzzer, and the high-decibel buzzer sounds an alarm to provide a warning.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figure 1-4 This embodiment provides the following technical solution: an online water level detection device, including a water storage tank 1. A reserved hole is provided at the bottom of one side of the water storage tank 1. A four-way connector is fixedly connected in the reserved hole. The other interfaces of the four-way connector are respectively connected to a pressure sensor 2, a transparent liquid level tube 3, and a drain pipe 4. A shut-off valve is provided between the pressure sensor 2, the transparent liquid level tube 3, the drain pipe 4, and the four-way connector. The left end interface of the four-way connector is fixedly connected to the reserved hole on the water storage tube, so that the four-way connector communicates with the inside of the water storage tube. The right end of the four-way connector is fixedly connected to the pressure sensor 2 through a shut-off valve 6. The upper end of the four-way connector is fixedly connected to the transparent liquid level tube 3 through a shut-off valve 6. The lower end of the four-way connector is fixedly connected to the drain pipe 4 through a shut-off valve 6.

[0031] Pressure sensor 2 is connected to a bar graph display instrument. Pressure sensor 2 collects the pressure signal at the bottom of water tank 1 in real time and transmits it to the bar graph display instrument. The bar graph display instrument processes the pressure signal and converts it into a percentage bar graph and the tonnage value in the tank for display. The staff can intuitively understand the liquid level of water tank 1 through the bar graph display instrument.

[0032] A fixing seat 5 is fixedly connected to the outer side of the upper end of the transparent liquid level tube 3. The fixing seat 5 is fixedly connected to the outer wall of the top of the water storage tank 1. In some embodiments, the transparent liquid level tube 3 is set along the height direction of the water storage tank 1, and the upper end of the transparent liquid level tube 3 is higher than the highest liquid level in the water storage tank 1. Through the transparent liquid level tube 3, the staff can directly observe the transparent liquid level tube 3 to understand the liquid level of the water storage tank 1.

[0033] A vent valve 7 is fixedly connected to the upper end of the transparent liquid level tube 3. In order to ensure that the transparent liquid level tube 3 and the water storage tank 1 form a "communicating vessel" and make the liquid level display more accurate, the upper end of the transparent liquid level tube 3 is open. The vent valve 7 ensures that the inside of the transparent liquid level tube 3 is connected to the atmosphere to balance the air pressure, while preventing impurities from entering and avoiding blockage or contamination.

[0034] The transparent liquid level tube 3 is equipped with a scale that is adapted to the height of the water storage tank 1. The scale on the transparent liquid level tube 3 makes it easier for staff to observe the liquid level in the water storage tank 1 directly.

[0035] The bar-shaped display instrument includes an LED light bar for dynamically displaying the percentage of liquid level that is full; a digital tube for displaying the percentage of liquid level and the tonnage value in storage tank 1; a buzzer for issuing an alarm when the liquid level is abnormal; and a control module in the control box for receiving the liquid level signal from pressure sensor 2 and outputting corresponding control signals to the water treatment system and the buzzer according to preset thresholds.

[0036] The control module is either a PLC module or a relay module, which supports manual adjustment of preset threshold parameters. The PLC module or relay module is electrically connected to the LED light bar, digital tube, buzzer and pressure sensor 2, and is also electrically connected to the power supply module.

[0037] The control module presets three thresholds: when the liquid level is below 60%, a low liquid level trigger signal is linked with the water treatment system to start the purified water production equipment; when the liquid level is above 90%, a high liquid level signal is linked with the water treatment system to stop the purified water production equipment; when the liquid level is below 40% or the tonnage in the tank is below 8 tons, an ultra-low liquid level alarm signal triggers the buzzer, and the high-decibel buzzer sounds an alarm to provide a warning.

[0038] The working principle of this utility model is as follows: When the water storage tank 1 is working normally, the pressure sensor 2 and the shut-off valve 6 on the transparent liquid level tube 3 are both in the open state. The pressure sensor 2 collects the pressure signal at the bottom of the water storage tank 1 in real time and transmits it to the bar display instrument. The bar display instrument processes the pressure signal and converts it into a percentage bar chart and the tonnage value in the water storage tank 1 for display.

[0039] When the water level in storage tank 1 is below 60%, the bar graph display instrument outputs a low liquid level trigger signal, which controls the water purification equipment to start via a relay and replenish water into storage tank 1.

[0040] When the water level is above 90%, the bar graph display instrument outputs a high liquid level signal to control the water purification equipment to stop replenishing water.

[0041] When the water level is below 40% or the weight is 8 tons, the bar graph display instrument outputs an ultra-low liquid level alarm signal, triggering a buzzer to emit a high-decibel alarm accompanied by a flashing light, reminding staff to intervene manually in a timely manner.

[0042] Staff can routinely view percentage bar charts or tonnage values ​​through bar display instruments, or directly observe the transparent liquid level tube 3 to understand the liquid level in the water storage tank 1;

[0043] When the transparent liquid level tube 3 needs to be inspected, simply close the shut-off valve 6 on the transparent liquid level tube 3.

[0044] When pressure sensor 2 needs to be repaired, simply close the second shut-off valve 6 on pressure sensor 2; this will not affect the normal operation of water storage tank 1.

[0045] When drainage is needed, simply close the shut-off valve 6 on drain pipe 4.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
