[0002] In waters such as the Yangtze River and lakes, it is often necessary to monitor water flow rate, liquid level, turbidity sensors, oxygen content, ammonia nitrogen content, pH value and other parameters. There are many corresponding sensors in the prior art, but operators often use handheld detection equipment to test the data of the water at the test point and then record it manually. Each time, only the corresponding parameters at a certain depth can be tested, which is time-consuming and laborious and inefficient. Summary of the invention

[0004] In order to achieve the above purpose, the specific technical solution adopted by the present invention is:

[0005] A smart water gauge unit structure comprises an insulating shell, a sensor arranged in the shell, and a first connector and a second connector respectively arranged at two ends of the shell.

[0006] By connecting multiple smart water gauge unit structures in sequence to form an electronic water gauge with a longer length, the water gauge is placed in the watershed to be tested. The flow rate, liquid level, turbidity sensor, oxygen content, ammonia nitrogen content, pH value and other parameters of the water at different depths in the water area are detected through the sensors in the smart water gauge unit structure, and transmitted to the electronic water gauge unit controller. Then, it is transmitted to the background monitoring, viewing, and recording through the wireless transmission module of the controller. The detection is convenient, and the parameters at different depths can be tested at the same time, which is efficient and saves labor costs.

[0007] By setting up the smart water gauge unit structure, the number of smart water gauge unit structures can be selected according to needs to be assembled into different lengths; two adjacent smart water gauge unit structures are respectively recorded as the first electronic water gauge unit and the second electronic water gauge unit. When the two adjacent smart water gauge unit structures are connected, the pin of the first electronic water gauge unit connector is inserted into the corresponding jack of the second electronic water gauge unit socket, and the locking piece is sealed and connected to the fixing seat, which is convenient for disassembly and assembly and easy to carry.

[0008] Further optimized, the first connector includes a plug connector and a locking member arranged on the plug connector; the plurality of pins arranged at the end of the plug connector;

[0009] The second connector includes a fixing base and a socket arranged on the fixing base, wherein the socket is provided with the same number of jacks as the number of pins;

[0010] The two adjacent smart water gauge unit structures are respectively recorded as the first electronic water gauge unit and the second electronic water gauge unit. When the two adjacent smart water gauge unit structures are connected, the pin of the first electronic water gauge unit connector is inserted into the corresponding jack of the second electronic water gauge unit socket, which is easy to operate. At the same time, the locking piece is sealed and connected to the fixing seat, and the sealing effect is good, which prevents water leakage at the connection between the first connector and the second connector and causes a short circuit.

[0011] The data detected by the sensor of the smart water gauge unit structure is transmitted to the controller in sequence through the pins.

[0012] Further optimized, the plug connector includes a connecting piece and a plug-in piece, the connecting piece and the plug-in piece are both cylindrical or truncated cone bodies, and the two are connected and coaxially arranged, wherein the diameter of the connecting piece is larger than that of the plug-in piece;

[0016] The inner wall of the barrel-shaped structure of the locking member is provided with an internal thread; the fixing seat of the second connector is a cylinder or a truncated cone, and the outer wall of the fixing seat is provided with an external thread;

[0017] When two adjacent smart water gauge unit structures are connected, the locking piece of the first electronic water gauge unit is mounted on the fixing seat of the corresponding second electronic water gauge unit, and the two are threadedly connected; a first sealing ring is arranged between the first pressure ring of the first electronic water gauge unit and the fixing seat of the second electronic water gauge unit, and at the same time, a second sealing ring is also arranged between the bottom of the locking piece of the first electronic water gauge unit and the pressure ring.

[0018] The threaded connection has good structural stability and is easy to assemble and disassemble. The second sealing ring is provided to further improve the waterproof sealing performance.

[0030] The pin of the first connector is electrically connected to the circuit board, and the metal contact in the socket of the second connector is electrically connected to the circuit board.

[0031] Insert the water gauge into the water area to be tested. Since water is conductive, the sensitive element in the water is connected to the metal block through the water to form a loop. When different sensitive elements are turned on, the corresponding current value of the detection circuit is different. The control module calculates the current value in the detection circuit and obtains the corresponding liquid level value, so that different current values ​​correspond to a scale line on the detection ruler one by one. It is easy to operate and has high detection accuracy.

[0032] Further optimization, the housing is also provided with an angle sensor. Since the water gauge is long, the water flow rate is different at different depths, so the electronic water gauge will tilt in the water. The angle sensor measures the tilt angle of each smart water gauge unit structure and sends it to the controller. The controller can calculate the corresponding water level depth and the flow rate at the depth according to the tilt angle.

[0033] Further optimization, the shell is cylindrical as a whole, and is composed of two half shells with semicircular end faces. It is easy to produce, process and assemble, and the two half shells are fastened and connected by screws, and the connection is treated with sealant.

[0035] By connecting multiple smart water gauge unit structures in sequence to form an electronic water gauge with a longer length, the water gauge is placed in the watershed to be tested. The flow rate, liquid level, turbidity sensor, oxygen content, ammonia nitrogen content, pH value and other parameters of the water at different depths in the water area are detected through the sensors in the smart water gauge unit structure, and transmitted to the electronic water gauge unit controller. Then, it is transmitted to the background monitoring, viewing, and recording through the wireless transmission module of the controller. The detection is convenient, and the parameters at different depths can be tested at the same time, which is efficient and saves labor costs.

[0075] Since the water gauge is long and the water flow rate is different at different depths, the electronic water gauge will tilt in the water. The angle sensor measures the tilt angle of each smart water gauge unit structure and sends it to the controller.

There is no need to set up liquid level sensors and flow sensors, saving costs.
