TECHNICAL FIELD
[0001] The utility model relates to water level early warning equipment technical field, concretely is a water level alarm device for early warning. BACKGROUND
[0002] Urban flood disaster refers to the waterlogging phenomenon caused by natural factors such as heavy rainfall, river flooding, and tidal water surge in urban areas, especially in low-lying areas such as underpass tunnels, where water is difficult to drain quickly and often becomes a disaster area of urban flood disaster.
[0003] When a flood disaster occurs in a city, the underpass tunnel is relatively low and the water is more serious. When a car drives in, it is impossible to predict the water depth, which may cause the engine to stall and be scrapped due to high water level, and even the entire vehicle is submerged in water, causing serious economic loss and casualties. In addition, due to uneven distribution of underpass tunnels, the power network is difficult to cover a large area, and the cost is high, so there are still many underpass tunnels without water level alarm devices. In addition, the existing water level alarm device is mainly connected with the power network. When the flood disaster causes power failure, the water level alarm device will not have a warning effect, so it cannot provide timely water information for drivers and relevant departments, increasing the harm of flood disaster.
[0004] Therefore, it is necessary to provide a water level alarm device for early warning to solve the above problems. CONTENT OF THE UTILITY MODEL
[0005] The technical problem solved by the utility model is to provide a water level alarm device for early warning to solve the problem of uneven distribution of underpass tunnels, difficult coverage of power network in a large area, high cost, and many underpass tunnels without water level alarm devices. In addition, the existing water level alarm device is mainly connected with the power network and cannot be powered independently. When the flood disaster causes power failure, the water level alarm device will not have a warning effect, so it cannot provide timely water information for drivers and relevant departments.

[0010] Beneficial effect: Compared with the prior art, the utility model provides an early warning water level alarm device, which has a unique structure and is easy to use. When a vehicle travels to the underpass and rolls over the pressure plate, the pressure plate compresses the spring and drives the piston to move downward. The movement of the piston drives the crankshaft to rotate and drives the rotating shaft I to rotate through the meshing transmission of the ratchet and the pawl. After the rotating shaft I rotates, the rotation speed is transmitted to the output shaft of the forward and reverse generator through the meshing transmission of the large bevel gear I and the small bevel gear I, and the large bevel gear II and the small bevel gear II, thereby increasing the number of rotations of the output shaft of the forward and reverse generator and improving the power generation efficiency; the electric energy generated by the forward and reverse generator is stored in a battery and monitored and managed in real time through a battery management system. When the water level alarm device detects water accumulation in the underpass, it emits an ultrasonic wave to detect the depth of the water accumulation and transmits the detection signal to the display device for display.
[0011] This solution converts the mechanical energy generated by the vehicle when it is moving into electrical energy, realizing independent power supply for the water level alarm device and the display device. This not only solves the problems of irregular distribution of underpasses, difficulty in large-scale coverage of the mains power supply network, and high cost, but also improves the stability and reliability of the power supply, so that the detection signal can be stably transmitted to the display device for display, providing the driver with sufficient reaction time and avoiding the situation where the vehicle's engine stalls, is scrapped, or even casualties due to water accumulation.

The rotating shaft III17 is fixedly connected to the output shaft of the forward and reverse generator 20. There are various ways of connection.

[0024] There are many ways to install the crankshaft 4, the rotating shaft I6, the rotating shaft II13, and the rotating shaft III17. For example, the crankshaft 4, the rotating shaft I6, the rotating shaft II13, and the rotating shaft III17 are all rotatably installed in the housing 3 through the bearing seat 14; a flywheel 11 is fixedly installed in the middle of the rotating shaft I6. There are many ways to install the flywheel 11. It can be concentrically arranged with the rotating shaft I6 or eccentrically arranged with the rotating shaft I6. In this application, the flywheel 11 is eccentrically arranged with the rotating shaft I6 to increase its moment of inertia and increase As the rotating shaft Ⅰ6 rotates, both ends of the rotating shaft Ⅰ6 are rotatably sleeved with sealing cylinders 5. There are various ways to install the sealing cylinder 5. For example, the two sealing cylinders 5 are rotatably sleeved on the rotating shaft Ⅰ6 through bearings. A ratchet 7 is fixedly sleeved on the rotating shaft Ⅰ6 in the sealing cylinder 5. A fixing rod 8 is fixedly installed on one side of the ratchet 7.

[0026] Working principle: When we use the water level alarm device, we first place the water level alarm device 1 in the low-lying area of the underpass, and set the display device 2 at the exit and entrance of the underpass. In addition, in order to allow the driver to have enough reaction time, the display device 2 should be set 50-100 meters away from the entrance and exit of the underpass, and then the power supply device is set in the water level alarm device 1. When the car passes through the underpass, the wheels will roll over the pressure plate 25, causing the pressure plate 25 to move downward. After the pressure plate 25 moves downward, the piston crankshaft mechanism drives the crankshaft 4 to rotate. After the crankshaft 4 rotates, the engagement transmission of the ratchet 7 and the pawl 9 drives the rotating shaft I6 to rotate. After the rotating shaft I6 rotates, it is driven by the engagement transmission of the large bevel gear I12 and the small bevel gear I16, and the large bevel gear II15 and the small bevel gear II19, thereby increasing the number of rotations of the output shaft of the forward and reverse generator 20.
[0027] In addition, after the rotating shaft I6 rotates, it will synchronously drive the flywheel 11 to rotate. Since the impact when the wheel rolls over the pressure plate 25 is large, and the flywheel 11 and the rotating shaft I6 are eccentrically arranged, when the car passes by, the pressure plate 25 returns to the starting position under the action of the spring 18, and the rotating shaft I6 will still rotate under the action of the flywheel 11. When the flywheel 11 cannot make a complete circle after rotating for a period of time, the flywheel 11 can still drive the rotating shaft I6 to rotate back and forth through reciprocating swing, and drive the output shaft of the forward and reverse generator 20 to rotate, thereby greatly improving the power generation efficiency. By using a power supply device, the mechanical energy of the car's movement is converted into electrical energy to power the water level alarm device 1 and the display device 2, thereby achieving the purpose of independent power supply. This not only solves the problems of irregular distribution of underpasses, difficulty in large-scale coverage of the mains power supply network, and high cost; when there is water accumulation in the underpass, the water level alarm device 1 emits an ultrasonic wave to detect the depth of the water accumulation, and then transmits the detection signal to the display device 2 for display. In addition, the buried ultrasonic water level detector can also send water accumulation information to relevant departments through a built-in wireless transmission device.
[0028] Example 2: The difference between Example 2 and Example 1 is that Figure 1-3 As shown, a transition slope is provided at the edge of the top of the pressure plate 25, and the bottom edge of the transition slope is connected to the ground. By setting the transition slope, not only can the damage of the edge of the pressure plate 25 to the car tire be reduced, but also pedestrians can be prevented from being tripped by the pressure plate 25. In addition, in order to further allow the driver to have enough reaction time, a display device 2 can be set every 50 meters at the entrance and exit 150 of the underpass.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
