Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring, and particularly relates to an intelligent measuring device for water conservancy projects. Background Technique

[0002] Water level monitoring is a key technology for real-time monitoring of water level changes in water bodies, which is of great significance for water conservancy projects, natural disaster prevention, and water resource management.

[0003] The existing Chinese patent: An intelligent water level rod for water conservancy projects, patent number: CN217111075U, includes a water level measuring mechanism, an alarm mechanism, and a protection mechanism. The water level measuring mechanism includes a bottom plate and a second connecting box body. The bottom plate is fixedly connected with a fixing rivet, and the bottom plate is fixedly connected with a connecting pipe. The connecting pipe is fixedly connected with a water inlet pipe. The second connecting box body is fixedly connected with a wireless signal transceiver, and the second connecting box body is fixedly connected with a liquid level gauge. The liquid level gauge is located inside the connecting pipe. The floating objects are blocked by a protection plate to protect the device. At the same time, the telescopic rod and the spring are compressed and deformed to absorb and damp the impact force to protect the device. The protection barrel is driven by the protection plate to rotate along the connecting pipe, and the impact force on the front is decomposed, so that the floating objects can pass through the surface of the device smoothly.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: The above-mentioned measuring device will only trigger an alarm and send out a wireless signal when the water level reaches the warning water level, and it cannot measure the water level before the water level reaches the warning water level, nor can it detect the rising speed of the water level. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides an intelligent measuring device for water conservancy projects, which solves the technical problems that the above-mentioned measuring device will only trigger an alarm and send out a wireless signal when the water level reaches the warning water level, and it cannot measure the water level before the water level reaches the warning water level, nor can it detect the rising speed of the water level.

[0007] (II) Technical Solutions

[0008] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0009] An intelligent measuring device for water conservancy projects includes an outer cylinder. An inner cylinder is fixedly installed inside the outer cylinder. A fixed plate is fixedly installed between the outer cylinder and the inner cylinder. A plurality of metal sensors are evenly fixedly installed on the fixed plate. A floating buoy is installed inside the inner cylinder. A metal sheath is installed on the outer side wall of the floating buoy. A control box is fixedly installed at the top end of the outer cylinder. Four storage cylinders are fixedly installed on the outer cylinder. A plug rod is slidably installed inside the storage cylinder. A threaded rod is rotatably installed inside the storage cylinder; the threaded rod is threadedly connected to the plug rod. A knob is fixedly installed at the top end of the threaded rod. A storage battery is fixedly installed at the top end of the outer cylinder. An LED light-emitting board is fixedly installed at the top end of the outer cylinder.

[0010] Preferably, exhaust holes are opened at the top end of the inner cylinder.

[0011] Preferably, four filter screens are fixedly installed at the bottom end of the inner cylinder.

[0012] (III) Beneficial effects

[0013] First, place the outer cylinder in the water area to be monitored. Rotate the four knobs clockwise. The knobs will drive the threaded rods to rotate. Since the threaded rods are threadedly connected to the plug rods, and the plug rods are slidably connected to the storage cylinders, therefore, when the threaded rods rotate clockwise, they will push the plug rods to slide downward. The downward-sliding plug rods will be inserted into the soil at the bottom of the water to complete the fixation. Since the knobs are located at the top end of the outer cylinder, the installation can be completed by operating on the water surface. And the plug rods are relatively long, so they can penetrate deep into the soil. By rotating the knobs to extend the plug rods, the effect of convenient disassembly and assembly can be achieved.

[0014] Second, during use, water flows into the inside of the inner cylinder from the bottom end of the inner cylinder. When the water flows in, the impurities in the water will be filtered outside by the filter screens. After the water flows into the inside of the inner cylinder, the floating buoy floats on the water surface under the buoyancy of the water. During the rising process of the floating buoy, the metal sheath on the outer side wall will trigger the passing metal sensors. The corresponding metal sensors will send electrical signals to the control box. The multiple metal sensors are located at different heights, and the distance between each metal sensor is equal. After the control box recognizes the sent signals, it will send the water level information to the central computer. When the water level rises, it will trigger the metal sensors from bottom to top. The central computer can know the rising speed of the water level according to the time difference between the triggering of two adjacent metal sensors. When the water level rises relatively fast or rises to the warning water level, the LED light-emitting board can be made to emit light through the control box to give an alarm to remind the surrounding people to take shelter. By the rising metal sheath triggering multiple metal sensors, the effect of being able to accurately measure the water level before the alarm and the rising and falling speed of the water level can be achieved.

[0022] Embodiments of the present application provide an intelligent measuring device for water conservancy projects, effectively solving the technical problems of the above-mentioned measuring device that only triggers an alarm to send a wireless signal when the water level reaches the warning water level, cannot measure the water level before it reaches the warning water level, and cannot detect the rising speed of the water level. Place the outer cylinder in the water area to be monitored, and rotate the four knobs clockwise. The knobs will drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the insertion rod, and the insertion rod is slidably connected to the storage cylinder, when the threaded rod rotates clockwise, it will push the insertion rod to slide downward. The downward-sliding insertion rod will be inserted into the soil at the bottom of the water to complete the fixation. Since the knobs are located at the top of the outer cylinder, the installation can be completed by operating on the water surface. And the insertion rod is relatively long, so it can penetrate deep into the soil. By rotating the knob to extend the insertion rod, the effect of convenient disassembly and assembly is achieved. When in use, water flows into the inner part of the inner cylinder from the bottom end of the inner cylinder. When the water flows in, the impurities in the water will be filtered out by the filter screen. After the water flows into the inner part of the inner cylinder, the floating buoy floats on the water surface under the buoyancy of the water. During the rising process of the floating buoy, the metal sheath on the outer side wall will trigger the passing metal sensor. An electrical signal is sent to the control box through the corresponding metal sensor. A plurality of metal sensors are located at different heights, and the distance between each metal sensor is equal. After the control box recognizes the sent signal, it will send the water level information to the central computer. When the water level rises, the metal sensors will be triggered from bottom to top. The central computer can know the rising speed of the water level according to the time difference between the triggering of two adjacent metal sensors. When the water level rises rapidly or the water level rises to the warning water level, the LED light-emitting board can be made to emit light through the control box to give an alarm to remind the surrounding people to take shelter. By triggering a plurality of metal sensors through the rising metal sheath, the effect of accurately measuring the water level before the alarm and the rising and falling speed of the water level is achieved.

[0023] Embodiment

[0024] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the technical solution in the embodiments of the present application effectively solves the above-mentioned technical problems of the measuring device that only triggers an alarm to send a wireless signal when the water level reaches the warning water level, cannot measure the water level before it reaches the warning water level, and cannot detect the rising speed of the water level. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the present utility model provides an intelligent measuring device for water conservancy projects, including an outer cylinder 1. An inner cylinder 2 is fixedly installed inside the outer cylinder 1. A fixed plate 5 is fixedly installed between the outer cylinder 1 and the inner cylinder 2. A plurality of metal sensors 6 are evenly and fixedly installed on the fixed plate 5. A floating buoy 3 is installed inside the inner cylinder 2. A metal sheath 4 is installed on the outer side wall of the floating buoy 3.

[0026] A control box 7 is fixedly installed at the top end of the outer cylinder 1. Four storage cylinders 12 are fixedly installed on the outer cylinder 1. A plug rod 14 is slidably installed inside the storage cylinder 12, and a threaded rod 13 is rotatably installed inside the storage cylinder 12; the threaded rod 13 is threadedly connected to the plug rod 14.

[0027] The top end of the threaded rod 13 is fixedly installed with a knob 15. The top end of the outer cylinder 1 is fixedly installed with a storage battery 8. The top end of the outer cylinder 1 is fixedly installed with an LED light-emitting panel 11. An exhaust hole 9 is opened at the top end of the inner cylinder 2. Four filter screens 16 are fixedly installed at the bottom end of the inner cylinder 2.

[0028] Working principle:

[0029] First step, the control box 7 integrates an ESP32-M1 Reach Out WiFi development board and an LED driver board. The metal sensor 6, the control box 7, the storage battery 8, and the LED light-emitting panel 11 are connected by wires. Place the outer cylinder 1 in the water area to be monitored. Rotate the four knobs 15 clockwise. The knob 15 will drive the threaded rod 13 to rotate. Since the threaded rod 13 is threadedly connected to the plug rod 14, and the plug rod 14 is slidably connected to the storage cylinder 12, therefore, when the threaded rod 13 rotates clockwise, it will push the plug rod 14 to slide downward. The downward-sliding plug rod 14 will be inserted into the soil at the bottom of the water to complete the fixation. Since the knob 15 is located at the top end of the outer cylinder 1, the installation can be completed by operating on the water surface. And the plug rod 14 is relatively long, so it can penetrate deep into the soil. By rotating the knob 15 to extend the plug rod 14, the effect of convenient disassembly and assembly can be achieved.

[0030] Second step, during use, water flows into the inside of the inner cylinder 2 from the bottom end of the inner cylinder 2. When the water flows in, the impurities in the water will be filtered outside by the filter screen 16. After the water flows into the inside of the inner cylinder 2, the floating ball 3 floats on the water surface under the buoyancy of the water. During the rising process of the floating ball 3, the metal sheath 4 on the outer side wall will trigger the passing metal sensor 6. An electrical signal is sent to the control box 7 through the corresponding metal sensor 6. The multiple metal sensors 6 are located at different heights, and the distance between each metal sensor 6 is equal. After the control box 7 recognizes the sent signal, it will send the water level information to the central computer. When the water level rises, the metal sensor 6 will be triggered from bottom to top. The central computer can know the rising speed of the water level according to the time difference between the triggering of two adjacent metal sensors 6. When the water level rises relatively fast or the water level rises to the warning water level, the LED light-emitting panel 11 can be made to emit light through the control box 7 to give an alarm to remind the surrounding people to take refuge. By triggering multiple metal sensors 6 with the rising metal sheath 4, the effect of accurately measuring the water level before the alarm and the rising and falling speed of the water level can be achieved.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
