Technical Field

[0001] The utility model relates to the technical field of water conservancy, in particular to a river water level measuring device for flood prevention and early warning. Background Art

[0002] Water level gauges are used in water conservancy and hydropower projects to monitor the water level in the area. The water level gauge uses the position of the float on the horizontal plane to measure the water level. However, since the water in the reservoir floats, directly measuring the position of the float on the scale is not only inconvenient but also prone to errors.

[0003] To this end, the Chinese patent technical document with announcement number CN219977517U discloses a water level measuring device, including a water level measuring rod, a slide groove is provided on the surface of the water level measuring rod, a measuring mechanism is arranged in the slide groove, the measuring mechanism includes a slide rod, the slide rod is fixedly connected in the slide groove, a sliding sleeve is provided on the surface of the slide rod, a floating plate is fixedly connected to the side of the slider away from the slide groove, a limiting groove is provided on the side of the floating plate close to the slide groove, a groove is provided inside the slide groove, and a rotating shaft is rotatably connected in the groove.

[0004] In the above technical solution, by moving the card rod and then rotating the shaft, the limit rod is finally rotated to the inside of the limit groove. At this time, the limit rod and the limit groove complete mutual blocking, thereby fixing the position of the float plate, facilitating subsequent checking of the position of the float plate, and effectively improving the accuracy of the water level measuring rod in water level measurement. However, in actual use, it was found that the water level measuring device lacks a corresponding early warning structure, which makes it inconvenient for staff to quickly know the water level changes. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a river water level measuring device for flood prevention and early warning, which can facilitate staff to grasp the water level changes in a timely manner.

[0006] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a river water level measuring device for flood prevention and early warning, comprising a main body, an insertion portion for inserting into the riverbed is provided at the bottom of the main body, a mounting cavity is provided in the main body, a floatable measuring mark is provided in the mounting cavity, a target plate connected to the measuring mark is provided on the outer periphery of the main body, an outwardly offset mounting seat is provided on the top of the main body, a photoelectric sensor opposite to the target plate is provided on the mounting seat, the photoelectric sensors are multiple and evenly distributed around the circumference, and an early warning light corresponding to the photoelectric sensor is provided on the mounting seat.

[0007] The utility model is further configured as follows: the main body is provided with a water inlet arranged along the vertical direction, the water inlet is multiple and evenly distributed along the circumference, the water inlet is connected to the installation cavity, a float is provided at the bottom of the measuring mark, a connecting guide seat is provided between the float and the measuring mark, and the two ends of the connecting guide seat are respectively connected to the float and the measuring mark.

[0008] The utility model is further configured as follows: a threaded hole is provided on the connecting guide seat, and the threaded holes are multiple and evenly distributed along the circumference. The threaded hole and the water inlet are located on the same axis. A connecting rod is provided between the connecting guide seat and the target plate.

[0009] The utility model is further configured as follows: a slot adapted to the measuring mark rod is provided on the connecting guide seat, and the measuring mark rod can be inserted into the slot to form a limiting fit between the two.

[0010] The utility model is further configured as follows: a through-hole is provided on the mounting seat, the through-hole corresponds to the photoelectric sensor, a connecting seat is fixed on the photoelectric sensor, a through-first connecting hole is provided on the connecting seat, a second connecting hole opposite to the first connecting hole is provided on the mounting seat, and the first connecting hole and the second connecting hole are connected by a locking member.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Since multiple photoelectric sensors are arranged on the mounting base, the detection ranges of the various photoelectric sensors can be made different by turning the adjustment knobs of the various photoelectric sensors. Therefore, after the main body is inserted into the riverbed, when the target plate floats following the measuring benchmark, each photoelectric sensor can detect the target plate one by one, thereby lighting up the corresponding early warning light, so that the staff can quickly know the water level changes. Therefore, the technical problem that the existing technology cannot provide effective early warning of the water level is effectively solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 4 As shown, the utility model discloses a river water level measuring device for flood prevention and early warning, comprising a main body 1, an insertion portion 101 for inserting into a riverbed is provided at the bottom of the main body 1, a mounting cavity is provided in the main body 1, a floating measuring mark rod 2 is provided in the mounting cavity, a target plate 3 connected to the measuring mark rod 2 is provided on the outer periphery of the main body 1, a mounting seat 4 offset outward is provided on the top of the main body 1, a photoelectric sensor 5 opposite to the target plate 3 is provided on the mounting seat 4, the photoelectric sensors 5 are multiple and evenly distributed along the circumference, and an early warning light 6 corresponding to the photoelectric sensor 5 is provided on the mounting seat 4. Since multiple photoelectric sensors 5 are provided on the mounting seat 4, the detection ranges of the various photoelectric sensors 5 are different from each other by rotating the adjustment knobs of the various photoelectric sensors 5. Therefore, after the main body 1 is inserted into the riverbed, when the target plate 3 floats following the measuring mark rod 2, the various photoelectric sensors 5 can detect the target plate 3 one by one, thereby lighting up the corresponding early warning light 6, so that the staff can quickly know the water level change.

[0020] In this embodiment, a total of three photoelectric sensors 5 and three warning lights 6 are equipped. By turning their respective adjustment knobs, the detection ranges of the photoelectric sensors 5 are A1, A2, and A3, respectively, where A1 is smaller than A2, and A2 is smaller than A3. The colors of the three warning lights 6 are green, yellow, and red, respectively, which are recorded as L1, L2, and L3. In this way, after the target plate 3 follows the measuring mark 2 and floats to the detection range of A1, it means that the water level is low and in the safe area, so L1 is lit. Similarly, after the target plate 3 follows the measuring mark 2 and floats to the detection range of A2, it means that the water level is in the warning area, and L2 is lit. Similarly, the target plate 3 follows the measuring mark 2 and floats to the detection range of A2, it means that the water level is in the warning area, and L2 is lit. After the board 3 follows the measuring mark 2 and floats to the detection range of A3, it means that the water level is in the danger zone at this time, and L3 lights up. In addition, the present scheme adopts a PLC controller for control, that is, after the PLC controller receives the control signal from the photoelectric sensor 5, it controls the corresponding warning light 6 to light up. The PLC controller, the warning light 6 and the photoelectric sensor 5 are all equipped with corresponding wireless receiving modules and wireless sending modules. Therefore, wireless communication is adopted between the PLC controller, the warning light 6 and the photoelectric sensor 5. The wireless communication between the controller and the actuator and the sensing element is all existing technology, so it will not be elaborated here.

[0021] In this embodiment, the principle of the floating of the measuring mark 2 is that a water inlet 102 arranged in the vertical direction is provided on the main body 1, and there are multiple water inlets 102 and they are evenly distributed around the circumference. The water inlet 102 is connected to the installation cavity, and a float 7 is provided at the bottom of the measuring mark 2. A connecting guide seat 8 is provided between the float 7 and the measuring mark 2, and the two ends of the connecting guide seat 8 are respectively connected to the float 7 and the measuring mark 2. After the main body 1 is inserted into the riverbed through the insertion part 101 to fix the main body 1, the river water can flow into the installation cavity through the water inlet 102 to provide buoyancy to the float 7, thereby driving the measuring mark 2 to float. After the measuring mark 2 is stable, the water level can be calculated by observing the distance between the scale at the top of the measuring mark 2 and the top of the main body 1.

[0022] In this embodiment, a threaded hole 81 is further provided on the connecting guide seat 8, and the threaded holes 81 are multiple and evenly distributed around the circumference. The threaded holes 81 and the water inlet 102 are located on the same axis. A connecting rod 9 is provided between the connecting guide seat 8 and the target plate 3. One end of the connecting rod 9 is threadedly connected to the threaded hole 81, and the other end is provided with a plug-in protrusion 91. The target plate 3 is located on the side facing the connecting rod 9. The plug-in hole is for the plug-in protrusion 91 to be inserted between the two and fixed by friction. In this way, by screwing the connecting rod 9 into or out of the threaded hole 81, and inserting or pulling out the target plate 3 into or out of the plug-in hole, a detachable connection between the target plate 3 and the connecting guide seat 8 can be achieved, thereby facilitating the disassembly and assembly of the whole, that is, after the connecting guide seat 8 is installed into the mounting cavity, the target plate 3 is connected to the connecting rod 9 and the connecting guide seat 8.

[0023] In this embodiment, the connection structure between the measuring mark rod 2 and the connecting guide seat 8 is that a slot adapted to the measuring mark rod 2 is further provided on the connecting guide seat 8, and the measuring mark rod 2 can be inserted into the slot to form a limiting fit between the two. In this way, after the measuring mark rod 2 is inserted into the slot, it can be fixed by the friction force generated between the two, so that a detachable connection can be formed between the measuring mark rod 2 and the connecting guide seat 8, thereby further facilitating the disassembly and assembly of the whole.

[0024] In this embodiment, the mounting structure of the photoelectric sensor 5 is that a through-hole 41 is further provided on the mounting base 4, and the through-hole 41 corresponds to the photoelectric sensor 5. A connecting base 51 is fixed on the photoelectric sensor 5, and the connecting base 51 is provided with a through-first connecting hole. The mounting base 4 is provided with a second connecting hole 42 opposite to the first connecting hole. The first connecting hole and the second connecting hole 42 are connected by a locking member. When installing the photoelectric sensor 5, the photoelectric sensor 5 is first inserted into the through-hole 41, and after the second connecting hole 42 is opposite to the first connecting hole, the photoelectric sensor 5 can be installed by screwing in a screw that forms a threaded match with the first connecting hole and the second connecting hole 42.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
