Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring devices, and in particular to a water level monitoring device for a water conservancy and hydropower project. Background Art

[0002] At present, water conservancy and hydropower engineering mainly studies the basic knowledge and skills of water resources, hydraulic structures, water conservancy engineering technology, etc., and conducts survey, planning, design, construction, and management of water conservancy and hydropower engineering. In order to ensure the water level in the river of water conservancy and hydropower engineering, it is necessary to monitor the water level in real time. The existing technical experience platform for water level monitoring devices used in water conservancy construction has problems such as single structure, poor practicality, lack of practical and reliable probes when ships measure water areas, and potential safety hazards. In the actual operation process, it brings certain difficulties.

[0003] The authorization announcement number in the prior art is: CN215448121U, and the name is: a water level monitoring device for water conservancy and hydropower projects, including a mounting plate, a limit plate, a connecting plate, a tape, a scale line, a connecting rod and a clamping piece. The limit plate is fixed on the top of the mounting plate, and the connecting plate is slidably sleeved on the limit plate. The front of the connecting plate is bonded with a tape, and a scale line is opened on the limit plate to indicate the water level height. A connecting rod is slidably sleeved on the mounting plate, and a floating ball is fixedly connected to the bottom end of the connecting rod. Clamping pieces are provided on both sides of the connecting rod, and an oily pen is provided on the clamping piece. The tip of the oily pen is slidably connected to the tape, and a shielding plate is movably sleeved on the top of the connecting plate and the limit plate. The patent uses the floating ball on the water surface, and the rise and fall of the water surface respectively drive the oily pen to record the range of water level activities, thereby reducing costs and being conducive to long-term use. However, the patent uses the oily pen to record the height of the water level when it is used, but the oily pen will fail after being exposed to the air for a long time, making it impossible to use continuously, and the practical effect is poor.

[0004] The application publication number in the prior art is: CN112268599A, and the name is: A water level monitoring device for water conservancy and hydropower projects, including a device shell, a water tank, a buoy, a No. 1 connecting rod, a No. 1 baffle, an alarm switch and an alarm device. A water tank is arranged at the bottom of the device shell, the upper end of the water tank is movably connected to the lower end of the buoy, the upper end of the buoy is fixedly connected to the lower end of the No. 1 connecting rod, the upper end of the No. 1 connecting rod is fixedly connected to the left lower end of the No. 1 baffle, the right upper end of the No. 1 baffle is set as an inclined plane, the right upper end of the No. 1 baffle is movably connected to the left lower end of the alarm switch, the right end of the alarm switch is slidably connected to the left end of the alarm device, and the alarm device is fixedly connected to the right end of the fixed shell. By setting the buoy, when the water level in the water tank rises, the buoy rises accordingly, thereby pushing the No. 1 baffle to move upward. Since the upper right end of the No. 1 baffle is an inclined surface, it will squeeze the alarm switch when it moves upward, triggering the alarm device to sound an alarm. However, when using this patent, the buoy needs to be driven upward by the rising water level. Then, the rack and gear structures driven by the buoy are usually metal structures, which are heavy in themselves. It is difficult to drive them up by the buoy, making the water level not accurate enough when measuring. Utility Model Content

When the water level rises, the float 7 will rise accordingly, causing the top rod 9 to push the slider 10 to one side, so that the first spring 11 pops the pressure block 12 downward, and then turns on the touch switch 13, the buzzer alarm 4 sounds an alarm, notifying the staff to take preventive measures, making the monitoring more accurate.

[0029] like Figure 2 As shown, a vertical slot 14 is provided inside the vertical plate 3 , and the slider 10 is slidably connected inside the vertical slot 14 . A touch switch 13 is installed at the bottom of the vertical slot 14 , and the touch switch 13 is electrically connected to the buzzer alarm 4 .

[0030] like Figure 2 As shown, a transverse groove is provided inside the pressing block 12 , and the slider 10 is slidably connected inside the transverse groove. A first spring 11 is connected between the top wall of the vertical groove 14 and the top of the slider 10 , and the slider 10 passes through the interior of the vertical plate 3 .

[0031] like Figure 3 As shown, a limiting groove is provided inside the mounting plate 1, a limiting block 19 is slidably connected inside the limiting groove, and a third spring 20 is commonly connected between one side of the limiting block 19 and the side wall of the limiting groove.

[0032] In this embodiment, the mounting plate 1 is first fixed, and then the fixing block 2 is placed inside the square groove 21, and fixed by the limit block 19, so that the float 7 is located on the water surface. When the water level rises, the float 7 will rise accordingly, and the connecting rod 6 drives the top rod 9 to flip through the straight rod 8, thereby pushing the slider 10 to move to one side. When the slider 10 moves to a certain distance on the top of the pressure block 12, the slider 10 will slide out from the inside of the vertical plate 3, so that the pressure block 12 loses its limiting effect, and pops up downward due to the action of the first spring 11, so that the pressure block 12 contacts with the touch switch 13, and the buzzer alarm 4 sounds an alarm to notify the staff to take preventive measures, so that the measurement is more accurate and not easy to be damaged.
