[0004] Although the sliding float installed on the sliding rod of this device will rise and fall with the change of water level, the water level value can be read quickly and accurately according to the position of the sliding float; when the water level reaches the specified water level, it will also trigger the alarm device to sound an alarm.

[0005] However, when the water flow is very fast, after the water flows into the hollow groove from the water inlet of the equipment, the strong impact force of the water will impact the inner surface of the hollow groove, which will cause the water in the water level monitoring pile body to rise instantly, pushing up the float and touching the touch pressure switch; at this time, the water level in the water level monitoring pile body is much higher than the water level outside the water level monitoring pile body, which will cause the monitored value to be inaccurate. Summary of the Invention

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] See Figure 1-6 This is an embodiment of an automatic water level monitoring device of the present invention.

[0033] The device includes a water level tube 1, a slide rod 2 arranged in the water level tube 1, and a float 3 slidably arranged on the slide rod 2; wherein, the water level tube 1 is provided with an array of water-permeable holes 4 penetrating the tube wall, and a baffle 5 is provided on the inner side of the tube wall of the water level tube 1, and the baffle 5 is located above the water-permeable holes 4; a sealing cover is provided at the upper end of the water level tube 1, and a control box is provided at the upper end of the sealing cover, and a control chip connected to the power supply through a wire is provided in the control box; a single-chip microcomputer and a wireless transmission module are plugged into the control chip; an alarm light is also provided at the upper end of the control box, and the alarm light emits light under the control of the control chip.

[0034] The water level tube 1 is vertically set in the water, and the float 3 is set in the water level tube 1 and will float on the water surface due to the influence of buoyancy; when the water surface rises as a whole, the water outside the water level tube 1 will enter the water level tube 1 from the water-permeable hole 4 in the wall of the water level tube 1. At this time, the float 3 rises with the water surface. When the float 3 rises and touches the piezoelectric piece 16, the piezoelectric piece 16 will convert the pressure into an electrical signal and transmit it to the control chip. The control chip transmits the signal to the monitoring terminal through the wireless transmission module, so as to facilitate subsequent remedial measures for the rising water level in the downstream or surrounding areas; and the alarm light will light up to remind people around that the water level is at a dangerous height and keep people away from the water.

[0035] When the water flow is turbulent and huge waves are formed on the water surface, the water flow with strong impact force will pass through the water permeable hole 4 and enter the water level pipe 1. At this time, the water flow will impact on the baffle 5, and the baffle 5 will offset the impact force of the water flow, so that the impact force of the water entering the water level pipe 1 is reduced;

[0036] In addition, the device is provided with four water-permeable holes 4 on the same horizontal plane of the water level tube 1. Such four water-permeable holes 4 are provided in multiple in the vertical direction of the water level tube 1, so the baffle 5 is also provided in multiple in the vertical direction. In this way, when the water flow hits the inner wall of the water level tube 1, due to the space in the tube, the impact force of the water will be upward, and the baffle 5 can block the upward water flow, ensuring that the float 3 will not be directly pressed against the piezoelectric piece 16 due to the instantaneous influx of water into the water level tube 1.

[0037] The baffle 5 includes a horizontal plate 6 and a vertical plate 7 provided at one end of the horizontal plate 6 ; the vertical plate 7 partially overlaps with the orthographic projection area of ​​the main view of the water-permeable hole 4 .

[0038] The function of the vertical plate 7 is that when the water flows into the water level pipe 1 from the water permeable hole 4, the water flows impacting the vertical plate 7 can offset the first impact force of the water flow first, and the vertical plate 7 and the horizontal plate 6 are integrally formed to form a folded plate, which can further reduce the impact force of the water flow.

[0039] A filter screen 8 is provided on the water permeable hole 4. The effect of the filter screen 8 is to filter impurities in the water.

[0040] A stabilizing assembly is provided at the lower end of the water level pipe 1. The stabilizing assembly includes a mounting hole provided at the lower part of the water level pipe 1. A support rod 9 is provided in the mounting hole. A mounting platform 10 is provided at the lower end of the support rod 9. A pointed cone 11 is provided at the lower end of the mounting platform 10.

[0041] This device requires the entire water level pipe 1 to be placed vertically in the water flow, so the stabilizing assembly serves to stabilize the water level pipe in the river channel. The pointed cone 11 here serves to penetrate the riverbed and provide stability. The support rod 9 is tilted, and in conjunction with the mounting platform 10, it increases the contact area with the river channel, thereby improving stability.

[0042] The support rod 9 includes an arc-shaped plate 12 and a fixed plate 13 installed on one side of the arc-shaped plate 12. A fixed disk 14 is installed at one end of the fixed plate 13, and one end of the slide rod 2 is fixed on the fixed disk 14. The overall shape of the arc-shaped plate 12 is a triangular plate obliquely arranged on one side of the water level pipe 1, and the middle part of the triangular plate is concave downward.

[0043] The function of the curved plate 12 is that when water flows onto the curved plate 12 , the arc shape of the plate surface can reduce the impact force of the water flow. On the other hand, the concave curved surface can also utilize the impact force of the water flow to increase the stability of the water level pipe 1 .

[0044] A reinforcement column 15 is provided between the fixing plate 14 and the mounting platform 10 , and the overall shape of the reinforcement column 15 is a truncated cone.

[0045] The function of the reinforcement column 15 is to improve the connection between the mounting platform 10 and the fixing plate 14 and increase the stability of the water level pipe 1.

[0046] The arc plate 12 and the fixed plate 13 are integrally formed to form a support rod 9; there are four support rods 9, which are evenly distributed around the water level pipe 1, and the fixed plate 13 is inserted into the water level pipe 1, and a fixed plate 14 is provided between the four fixed plates 13 to increase the stability of the fixed plate 14.

[0047] The horizontal plate 6 and the vertical plate 7 are connected via a flexible plate 17 , and the flexible plate 17 is made of elastic steel.

[0048] The device is further provided with a stress ring 18 , which passes through the side surface of the vertical plate 7 , and the axis of the stress ring 18 coincides with the axis of the water level pipe 1 .

[0049] The function of the stress ring 18 is to fix the vertical plates 7 on the same horizontal plane together. When water hits the vertical plate 7 from one side, part of the impact force is transmitted to the flexible plate 17, and the flexible plate 17 is deformed under the force; the other part of the impact force is transmitted to the other three vertical plates 7 through the stress ring 18, and then transmitted to the flexible plate 17 connected to the three vertical plates 7, thereby reducing the impact force of the water flow.

[0050] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
