Description

Technical Field

[0001] The present invention relates to the field of measuring devices, and particularly to a floating water level warning device. Background Art

[0002] When conducting water conservancy work, it is often necessary to measure the water level of rivers, lakes and other places, and also to give early warnings about the water level to prevent the water level from being too high or too low. However, the existing water level warning devices generally measure the water level through detection devices fixed beside the water area and give early warnings when the water level is too high or too low. However, when in use, due to their fixed nature, they can only measure the water level at a single position on the edge of the water area. Therefore, when measuring large water areas such as lakes, the water level changes of the water area cannot be reflected, resulting in inaccurate water level measurement and inaccurate early warning of water level changes.

[0003] For example, a water conservancy project water level warning device proposed in CN202510353634.3 includes a float, a limiting mechanism, a mounting frame, a signal conversion and processing device, and a display device. A pressure sensor is provided at the bottom of the float; a flow baffle tube is sleeved outside the float, and the flow baffle tube is rotatably connected to the mounting frame. A plurality of vane plates are uniformly arranged along the rotation axis on the outer side of the lower part of the flow baffle tube, and the vane plates are arranged vertically. The float is located inside the flow baffle tube; the processor is electrically connected to an alarm and wirelessly connected to a mobile terminal. This invention uses a limiting mechanism to limit the float so that it can only move up and down, drives the sliding piece to move up and down, directly obtains the water level information through the signal conversion and processing device, and displays it on the display device. The structure is simple and reasonable, the cost is low, the structure is compact, the resistance during the working process is small, the action is smooth and sensitive, and the measurement result is highly accurate; the measurement result is directly displayed; the working condition of the float is judged by the pressure information fed back by the pressure sensor; a flow baffle tube is provided and it is also applicable when the water waves are large.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0030] Next, a floating water level warning device according to an embodiment of the present invention will be described with reference to the accompanying drawings. As Figures 1 - 9 shown in the figure, the floating water level warning device includes a housing 1, the housing 1 is annular, a photovoltaic panel 2 is provided on the housing 1 through a bracket 3, a storage battery is provided below the photovoltaic panel 2 for energy storage, a communication component 5 is also provided on the housing 1 for remotely transmitting the measured data and receiving the signals transmitted from the data center, and further includes a warning device provided on the outer side of the housing 1, a measuring device provided on the inner side of the housing 1, and a protection device provided below the housing 1.

[0031] As Figure 3 and Figure 4 shown, the floating water level warning device includes a warning device, the warning device includes a connecting plate 7 and a float 8, the connecting plate 7 is rotationally distributed around the outer side below the housing 1, the float 8 is fixed to the end of the connecting plate 7, a wire 15 is connected between the float 8 and the housing 1 for data transmission, an LED light board 26 is provided at the end of the float 8, and a cover plate 9 is provided for protection.

[0032] In a specific embodiment: during use, when the water level at this time exceeds the preset water level value range, the LED light board 26 will emit warning lights through the energy provided by the storage battery below the photovoltaic panel 2, thereby warning the water level value.

[0033] As Figure 4 , Figure 6 , Figure 7 ,Figure 8 and Figure 9 As shown, the floating water level warning device includes a measuring device, which includes a data processor 6, a winding wheel 10, a limit frame 11, a motor 14, a counterweight 16, a probe 18, a first mounting plate 20, a slide rail 21 and a second mounting plate 22. The data processor 6 is fixed on the housing 1, the winding wheel 10 is rotatably mounted on the side of the data processor 6, the limit frame 11 is fixed on the inner side of the housing 1, the winding wheel 10 is rotatably mounted on the limit frame 11, and the edge of the winding wheel 10 is provided with a flange The structure is shown in FIG. 1 . A bearing is arranged on the limit frame 11. The limit frame 11 contacts the edge of the winding wheel 10 through the bearing, so that the winding wheel 10 is more stable to prevent shaking and deformation. The motor 14 is fixed to the housing 1. A worm 13 is fixed to the output shaft of the motor 14. A gear 12 is fixed to the side of the winding wheel 10. The gear 12 is meshed with the worm 13. A wire 15 is wound around the winding wheel 10. One end of the wire 15 is connected to the data processor 6. A counterweight 16 is fixed to the other end of the wire 15. The counterweight 16 is fixed to the counterweight 16. 6 is a cone with a small top and a large bottom, so that the center of gravity of the counterweight 16 is not easy to tip over downward. A probe 18 is installed on the counterweight 16, and the probe 18 is connected to the data processor 6 through a wire 15. A touch ring 17 is slidably installed below the counterweight 16, and a spring is provided between the touch ring 17 and the counterweight 16. A touch switch 19 is provided below the counterweight 16, and the touch switch 19 is located above the touch ring 17. The first mounting plate 20 is fixed to the bottom of the shell 1, and the slide rail 21 is fixed to the bottom of the shell 1. The first mounting plate 20 is installed relative to the slide rail 21, and the second mounting plate 22 is slidably installed on the slide rail 21. The end of the second mounting plate 22 is connected to the end of the slide rail 21 with a spring. Guide wheels are rotatably provided above the first mounting plate 20 and the second mounting plate 22. The wire 15 is guided by the guide wheel on the first mounting plate 20, and a slot is provided in the middle of the guide wheel on the second mounting plate 22. The slot limits the wire 15 to prevent the wire 15 from escaping from the guide wheel on the first mounting plate 20.

[0034] In a specific embodiment: when in use, the second mounting plate 22 is pulled to guide the wire 15 through the guide wheel on the first mounting plate 20, and then the second mounting plate 22 is loosened so that the guide wheel on the second mounting plate 22 limits the wire 15, and then the motor 14 is controlled to rotate through the communication component 5, thereby driving the winding wheel 10 to rotate through the engagement between the worm 13 and the gear 12, so that the wire 15 with the counterweight block 16 below descends and sinks into the water. When the counterweight block 16 contacts the bottom of the water, the touch ring 17 will compress the spring and press the touch switch 19, thereby sending an electrical signal. At this time, the water pressure here is measured by the probe 18, and an electrical signal is sent to the data processor 6. After processing by the data processor 6, the water pressure value is converted into a water level value, and the signal of the water level value is transmitted through the communication component 5.

[0035] Meanwhile, due to the one-way transmission of the gear 12 and the worm 13, the wire 15 cannot pull the winding wheel 10 to rotate, so that the counterweight 16 forms an anchor at this time, thus fixing the position of this water level warning device and preventing this water level warning device from drifting away.

[0036] As Figure 2 , Figure 5 and Figure 6 shown, the floating water level warning device includes a protection device, and the protection device includes a second cover body 23, a first cover body 24 and a permanent magnet 25. The first cover body 24 is slidably installed below the housing 1, the second cover body 23 is slidably installed outside the first cover body 24, the housing 1 is provided with a storage groove that fits with the first cover body 24 and the second cover body 23, through holes are opened on the first cover body 24 and the second cover body 23, and the permanent magnet 25 is fixed below the housing 1, and the permanent magnet 25 can adsorb and fix the second cover body 23.

[0037] In a specific embodiment: during use, by pulling the second cover body 23, the second cover body 23 is disengaged from the adsorption of the permanent magnet 25, and the first cover body 24 is pulled out, so as to protect the inner wire 15 through the first cover body 24 and the second cover body 23 and prevent floating objects on the water surface from colliding with the wire 15.

[0038] Working principle: during use, by pulling the second cover body 23, the second cover body 23 is disengaged from the adsorption of the permanent magnet 25, and the first cover body 24 is pulled out. Then, the photovoltaic panel 2 converts light energy into electrical energy, and the electrical energy is stored through the battery below the photovoltaic panel 2. Then, the communication component 5 controls the motor 14 to rotate, so as to drive the winding wheel 10 to rotate through the meshing between the worm 13 and the gear 12, so that the wire 15 provided with the counterweight 16 below descends and sinks into the water. When the counterweight 16 touches the bottom of the water, the touch ring 17 will compress the spring and press the touch switch 19, thereby emitting an electrical signal. At this time, the water pressure here is measured through the probe 18, and an electrical signal is sent to the data processor 6. After being processed by the data processor 6, the water pressure value is converted into a water level value, and the signal of the water level value is transmitted through the communication component 5. Then, when the current water level exceeds the preset water level value range, the LED light board 26 will emit a warning light through the energy provided by the battery below the photovoltaic panel 2, so as to give a warning about the water level value.
