Description

Technical Field

[0001] The utility model belongs to the technical field of water level measurement, in particular to a water level measurement warning device. Background Art

[0002] Water level refers to the elevation of the free water surface relative to a certain base surface, and the distance between the water surface and the river bottom is called water depth. Water level is the most intuitive factor reflecting the water conditions of a water body, and its changes are mainly caused by the increase or decrease of the water volume of the water body. When typhoons and heavy rains come or other water-related natural disasters occur, it is necessary to monitor the water level of the water body in real time.

[0003] At present, in the process of water level monitoring, commonly used ultrasonic and radar level gauges are generally used to realize water level detection. However, ultrasonic and radar level gauges are expensive and power-hungry, which greatly increases the cost. Moreover, after long-term use, dust easily accumulates on the surface, which affects the detection accuracy of ultrasonic and radar level gauges, thereby affecting the water level measurement.

[0004] In view of this, a water level measurement warning device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a water level measurement warning device in order to solve the above-mentioned problems.

[0006] The technical solution adopted by the utility model is as follows: a water level measurement warning device, including a measuring rod, a floating ball that can move up and down due to buoyancy is sleeved on the outer side of the measuring rod, a sensing element is arranged on the top of the floating ball, an upper positioning ring is sleeved on the outer side of the measuring rod above the floating ball, a Hall sensor corresponding to the sensing element is embedded inside the upper positioning ring, a control box is installed on the top of the measuring rod, a sound and light alarm is arranged on one side of the control box, and a PCB mainboard electrically connected to the Hall sensor and the sound and light alarm is accommodated inside the control box;

[0007] If the Hall sensor senses the sensing element, the sound and light alarm will be powered on and sound and light alarm will sound.

[0008] In a preferred embodiment, a lower positioning ring is sleeved on the measuring rod at the lower side of the float, and both the lower positioning ring and the upper positioning ring are fixed to the measuring rod by bolts.

[0009] In a preferred embodiment, the outer surface of the measuring rod is provided with scales along the vertical direction.

[0010] In a preferred embodiment, the lower positioning ring, the upper positioning ring and the measuring rod are all made of stainless steel.

[0011] In a preferred embodiment, the bottom end surface of the Hall sensor is lower than the bottom end surface of the upper positioning ring.

[0012] In a preferred embodiment, a solar panel is embedded in the upper end surface of the control box, and a battery electrically connected to the solar panel and the PCB mainboard is also accommodated inside the control box.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the Hall sensor and the induction element are used as the water level measurement part. When the water level rises, the float and the induction element rise. When the Hall sensor senses the induction element, the signal is transmitted to the control box, indicating that the current water level has reached the position requiring warning. At this time, the sound and light alarm alarms to play a warning role, and the automatic measurement and automatic warning operation can be completed;

[0015] 2. In the present invention, the Hall sensor is used as the signal sensing part. Since the Hall sensor has small size, low cost, low power consumption and is not affected by water and gasoline pollution, it can reduce cost and energy consumption while ensuring detection accuracy;

[0016] 3. In the utility model, the water level measurement warning range can be adjusted according to different water bodies. When adjusting, it is only necessary to adjust the position of the upper positioning ring up and down, which is more applicable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] At the same time, since the Hall sensor 12 has the advantages of small size, low cost, low power consumption and is not affected by water and gasoline pollution, it can reduce costs and energy consumption while ensuring detection accuracy.

[0024] The induction element 6 is a magnet ring.

[0025] Furthermore, a lower positioning ring 9 is provided on the lower side of the float 7 on the measuring rod 4. The lower positioning ring 9 and the upper positioning ring 5 are fixed to the measuring rod 4 by bolts 10. The water level measurement warning range can be adjusted according to different water bodies. When adjusting, it is only necessary to loosen the bolts 10 of the upper positioning ring 5, and then adjust the position of the upper positioning ring 5 up and down and lock it. At this time, the distance between the float 7 and the upper positioning ring 5 can be adjusted, and the applicability is stronger.

[0026] In addition, the lower positioning ring 9, the upper positioning ring 5 and the measuring rod 4 itself can assist in positioning the lifting position of the float 7.

[0027] Furthermore, the outer surface of the measuring rod 4 is provided with a scale 8 in the vertical direction, and the scale 8 facilitates the staff to adjust the upper positioning ring 5 to a desired height, thereby ensuring the accuracy of subsequent measurements.

[0028] Furthermore, the lower positioning ring 9, the upper positioning ring 5 and the measuring rod 4 are all made of stainless steel. Since stainless steel has high corrosion resistance, it can be used in an underwater environment, thereby ensuring the overall service life.

[0029] Furthermore, the bottom end surface of the Hall sensor 12 is lower than the bottom end surface of the upper positioning ring 5 . The above design can prevent the Hall sensor 12 from directly contacting the sensing element 6 , and prevent the sensing element 6 from being damaged when it rises and contacts the upper positioning ring 5 .

[0030] Furthermore, a solar panel 2 (with other accessories such as an inverter, which will not be described in detail) is embedded in the upper end surface of the control box 1, and a battery 12 electrically connected to the solar panel 2 and the PCB main board 11 is also accommodated inside the control box 1. The solar panel 2 can absorb solar energy and store it in the battery 12, which can provide a power source for the overall operation of the equipment and save electricity.

[0031] It is known that the power source of the battery 12 can also come from an external mains electricity.

[0032] It should be mentioned that one side of the control box 1 is designed with a bracket or a support rod (with a mounting seat) for fixing the control box 1 as a whole on one side of the water level, and the specific structure of the bracket or the support rod will not be further elaborated.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
