Description

Technical Field

[0001] The invention belongs to the technical field of water area detection equipment, and specifically relates to a float type smart water gauge. Background Art

[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

[0003] The purpose of the present invention is to provide a float type intelligent water gauge to solve the technical problems in the prior art that the operator uses handheld detection equipment to test the water data of the test point and then records it manually, and can only test the corresponding parameters at a certain depth each time, which is time-consuming, labor-intensive and inefficient.

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

[0005] A float type intelligent water gauge, comprising an insulating float, a sensor arranged at the bottom of the float, and at least two water gauge units connected in sequence;

[0006] A solar panel is arranged on the top of the float, and a solar cell module, a control module, a GPS positioning module and a wireless communication module are arranged in the cavity of the float; an angle sensor is arranged in each water gauge unit; the solar panel receives solar energy through the solar cell module to power the control module, the wireless communication module, the GPS positioning module and all sensors.

[0007] The float-type smart water gauge is placed in the watershed to be measured. Since the float is relatively large in size and has great buoyancy, the float is in a floating state, making it easy to visually observe the specific position of the water gauge. At the same time, the float rises and falls with the rise and fall of the water level, driving the water gauge to move, making the measurement data more accurate.

[0008] By setting up solar panels, full use is made of solar energy, solving the problem of frequent battery replacement; because the power consumption of the water gauge is not particularly large, the solar energy received by the solar panel set on the top of the float is sufficient to enable it to work normally and continuously.

[0009] The sensor set at the bottom of the float detects the required parameters in the water area and transmits them to the control module, and then transmits them to the cloud server through the wireless transmission module, and then transmits them to the user terminal through the cloud server for monitoring, viewing, recording, etc. At the same time, by connecting multiple water gauge units in sequence, a long smart water gauge is formed and hung at the bottom of the float. Each water gauge unit is provided with an angle sensor. Since the water flow has an impact on the water gauge, the water gauge is tilted in the water, and the flow rate at different depths is different, then each water gauge unit is subjected to different water impacts, resulting in different tilt angles of different water gauge units. Each angle sensor transmits the measured angle to the control module, and then transmits it to the cloud server through the wireless transmission module for data processing, and obtains the specific depths corresponding to different water gauge units, as well as the flow rate at different depths, and finally transmits it to the user terminal through the cloud server for monitoring, viewing, recording, etc., which is very convenient, efficient, and saves labor costs. The terminal is a computer, a mobile phone, or / and a tablet computer, etc.

[0010] By setting the water level gauge unit, the number of water level gauge units can be selected according to the needs, and the water level gauge units can be detachably assembled into different lengths, which is convenient for disassembly and assembly and easy to carry.

[0011] The GPS positioning module sends the float position information to the cloud server through the wireless communication module, and then sends it to the user terminal through the cloud server, marking the exact position of the float water gauge on the map of the user terminal for easy viewing.

[0014] Due to environmental pollution, garbage, such as plastic bags and branches, floats on the surface of rivers, lakes and other watersheds. In order to prevent the floating garbage from entangled and hanging on the sensor and affecting its normal operation, a protective cover is set up so that the sensor is located in the protective cover, which plays a good protective role. Since the protective cover is fixed to the bottom of the float and has high strength, it is not easy to deform; in addition, by opening a number of small holes on the protective cover, the pressure inside and outside the protective cover is guaranteed to be the same, and the water quality is the same, thereby improving the accuracy of the detection results.

[0015] Since multiple water gauge units are connected and hung at the bottom of the float, the water gauge is relatively long, and the height of the protective cover is about 30-50cm. Therefore, the lower end of the water gauge extends out of the protective cover, and there is relatively little garbage below the water surface, so it will not affect the measurement accuracy of the water gauge.

[0016] Further optimization, the float includes a main body and an outer cover plate; the main body is in the shape of a cylinder with a bottom but no cover, recorded as an outer cylinder, the center part of the bottom of the outer cylinder is recessed inward and extends to form an inner cylinder, so that the inner cavity of the main body is annular as a whole, and the solar cell module, control module and wireless communication module are arranged in the annular inner wall; the height of the inner cylinder is lower than that of the outer cylinder, and an annular limit platform is circumferentially arranged on the top of the inner cylinder, and an inner cover plate is fixedly arranged on the limit platform, and a sealing gasket is arranged between the limit platform and the inner cover plate, which has a good sealing effect and prevents water seepage at the overlap from causing short circuit of the installed solar cell module, control module and wireless communication module.

[0019] The upper end of the protective cover is fixedly connected to the limit platform; the sensor and the water gauge unit connected in sequence are suspended at the bottom of the inner cover plate.

[0020] By setting the float to be split, including a main body and an outer cover, it is convenient to install the solar cell module, control module and wireless communication module in the cavity of the float, and the three modules are evenly distributed, so that the center of gravity of the float water gauge coincides with its geometric center, ensuring that the float will not tilt or even overturn when floating on the water.

[0034] Further optimized, the locking member is a cylindrical structure with a bottom but no cover, a first through hole is opened at the bottom of the locking member, the locking member is movably sleeved on the connecting member through the first through hole, and the diameter of the first through hole is smaller than the diameter of the first pressure ring;

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] 1. The present invention places the float-type smart water gauge in the watershed to be measured. Since the float is relatively large in size and has a large buoyancy, the float is in a floating state, which is convenient for visually observing the specific position of the water gauge. At the same time, the float rises and falls with the rise and fall of the water level, driving the water gauge to move, making the measurement data more accurate.

[0050] 2. By setting up solar panels, full use is made of solar energy, solving the problem of frequent battery replacement; because the power consumption of the water gauge is not particularly large, the solar energy received by the solar panel set on the top of the float is sufficient to enable it to work normally and continuously.

An angle sensor is set in each water gauge unit. Since the water flow has an impact on the water gauge, the water gauge is tilted in the water, and the flow rate at different depths is different, then each water gauge unit is subjected to different water impacts, resulting in different tilt angles of different water gauge units. Each angle sensor transmits the measured angle to the control module, and then transmits it to the cloud server through the wireless transmission module for data processing, and obtains the specific depths corresponding to different water gauge units, as well as the flow rate at different depths, and finally transmits it to the user terminal through the cloud server for monitoring, viewing, recording, etc., which is very convenient, efficient, and saves labor costs. The terminal is a computer, a mobile phone, or / and a tablet computer, etc.

[0063] The float-type smart water gauge is placed in the watershed to be measured. Since the float is relatively large in size and has great buoyancy, the float is in a floating state, making it easy to visually observe the specific position of the water gauge. At the same time, the float rises and falls with the rise and fall of the water level, driving the water gauge to move, making the measurement data more accurate.

[0064] By setting up solar panels, full use is made of solar energy, solving the problem of frequent battery replacement; because the power consumption of the water gauge is not particularly large, the solar energy received by the solar panel set on the top of the float is sufficient to enable it to work normally and continuously.

[0065] The sensor set at the bottom of the float detects the required parameters in the water area and transmits them to the control module, and then transmits them to the cloud server through the wireless transmission module, and then transmits them to the user terminal through the cloud server for monitoring, viewing, recording, etc. At the same time, by connecting multiple water gauge units in sequence, a long smart water gauge is formed and hung at the bottom of the float. Each water gauge unit is provided with an angle sensor. Since the water flow has an impact on the water gauge, the water gauge is tilted in the water, and the flow rate at different depths is different, then each water gauge unit is subjected to different water impacts, resulting in different tilt angles of different water gauge units. Each angle sensor transmits the measured angle to the control module, and then transmits it to the cloud server through the wireless transmission module for data processing, and obtains the specific depths corresponding to different water gauge units, as well as the flow rate at different depths, and finally transmits it to the user terminal through the cloud server for monitoring, viewing, recording, etc., which is very convenient, efficient, and saves labor costs.

[0070] Due to environmental pollution, garbage, such as plastic bags and branches, floats on the surface of rivers, lakes and other watersheds. In order to prevent the floating garbage from entangled and hanging on the sensor and affecting its normal operation, a protective cover is set up so that the sensor is located in the protective cover, which plays a good protective role. Since the protective cover is fixed to the bottom of the float and has high strength, it is not easy to deform; in addition, by opening a number of small holes on the protective cover, the pressure inside and outside the protective cover is guaranteed to be the same, and the water quality is the same, thereby improving the accuracy of the detection results.

[0071] Since multiple water gauge units are connected and hung at the bottom of the float, the water gauge is relatively long, and the height of the protective cover is about 30-50cm. Therefore, the lower end of the water gauge extends out of the protective cover, and there is relatively little garbage below the water surface, so it will not affect the measurement accuracy of the water gauge.
