DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem that manual monitoring of whether the water level has reached the warning water level not only leads to long working hours for workers but also easily results in underreporting, the utility model provides a water level meter with automatic alarm, which can realize automatic monitoring of whether the water level has reached the warning water level.

[0026] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a water level gauge capable of automatically giving an alarm in an embodiment of the utility model. The water level gauge capable of automatically giving an alarm comprises a water level measuring mechanism 1 and an alarm mechanism 2.

[0027] The water level measuring mechanism 1 includes a bracket 11, a turntable 12, a measuring rope 13, a float 14 and a counterweight 15. The lower end of the bracket 11 is fixed to the river bank 3. The turntable 12 is rotatably arranged on the bracket 11. The measuring rope 13 is wound around the turntable 12. The two ends of the measuring rope 13 are respectively fixedly connected to the float 14 and the counterweight 15. The measuring rope 13 is evenly marked with scale lines and corresponding readings. It should be understood that the weight of the counterweight 15 should be less than the weight of the float 14.

[0028] See also Figure 1 and Figure 2The alarm mechanism 2 includes a lifting member 21, a fixing block 22, a micro switch 23 and an alarm 24. The lifting member 21 is provided with a through hole 2121 for the measuring rope 13 to pass through. The fixing block 22 is fixed to the measuring rope 13. When the fixing block 22 moves to a preset height following the measuring rope 13, the fixing block 22 can drive the lifting member 21 to rise to contact with the contact of the micro switch 23, so that the alarm 24 sounds an alarm. It should be understood that the size of the fixing block 22 should be larger than the size of the through hole 2121, so that the fixing block 22 cannot pass through the through hole 2121, thereby driving the lifting member 21 to rise.

[0029] During use, when the water level rises or falls, the float 14 rises or falls accordingly. Under the action of the counterweight 15, the measuring rope 13 can always remain in a straightened state, and the water level value can be obtained by the indication of the measuring rope 13 at a certain fixed height; at the same time, when the measuring rope 13 rises or falls, it drives the fixed block 22 to rise or fall. When the fixed block 22 moves with the measuring rope 13 to contact the lifting member 21, the subsequent measuring rope 13 continues to rise, which will drive the lifting member 21 to rise. When the lifting member 21 rises to contact the contact of the micro switch 23, the alarm 24 sounds an alarm, thereby reminding the staff to take corresponding measures. Through this device, an automatic alarm can be sounded when the water level reaches the preset water level. The staff does not need to pay attention to the water level at all times, which can reduce the workload of the staff and avoid missed reports.

[0030] In one embodiment, see Figure 1-Figure 4 The alarm mechanism 2 also includes a power supply 25, and the power supply 25, the micro switch 23 and the alarm 24 are connected in series to form a closed loop.

[0031] In one embodiment, see Figure 1 and Figure 2 The alarm mechanism 2 also includes a fixing plate 26, which is fixed to the bracket 11 and has a guide hole. The lifting member 21 includes a vertical plate 211 and a horizontal plate 212, the vertical plate 211 is slidably inserted into the guide hole, the horizontal plate 212 is fixed under the vertical plate 211, and the through hole 2121 is formed on the horizontal plate 212.

[0032] In one embodiment, see Figure 1 and Figure 2The alarm mechanism 2 also includes a mounting tube 27 and a slider 28. The mounting tube 27 is fixed on the fixed plate 26. The slider 28 is slidably arranged in the mounting tube 27. One end of the slider 28 is fixedly connected to the vertical plate 211. The micro switch 23 is fixedly installed in the mounting tube 27. When in use, when the vertical plate 211 is raised or lowered, the slider 28 moves up and down in the mounting tube 27. Through the guidance of the mounting tube 27, the stability of the vertical plate 211 during the lifting and lowering process can be improved.

[0033] In one embodiment, see Figure 1 and Figure 2 The alarm mechanism 2 further includes a cushion block 29 , which is fixed on the slider 28 , and is used to abut against the contact of the micro switch 23 .

[0034] In one embodiment, see Figure 1 and Figure 2 A vent 271 is provided on the side wall of the installation tube 27. Preferably, a waterproof breathable membrane 272 is provided in the vent 271, so as to facilitate ventilation and heat dissipation while preventing rainwater from entering the installation tube 27.

[0035] In one embodiment, see Figure 1-Figure 3 The fixing block 22 includes a first clamping block 221 and a second clamping block 222, the first clamping block 221 and the second clamping block 222 are detachably connected, and the measuring rope 13 is clamped between the first clamping block 221 and the second clamping block 222. By making the first clamping block 221 and the second clamping block 222 detachably connected, it is convenient to adjust the position of the fixing block 22 fixed on the measuring rope 13, so as to select a suitable alarm water depth according to needs.

[0036] In one embodiment, see Figure 1-Figure 3 The first clamping block 221 and the second clamping block 222 are fixedly connected by a plurality of screws 223 .

[0037] In one embodiment, see Figure 1-Figure 3 An arc-shaped groove is formed on one side of the first clamping block 221 close to the second clamping block 222, and an arc-shaped protrusion 2221 that fits with the arc-shaped groove is formed on one side of the second clamping block 222 close to the first clamping block 221. The measuring rope 13 is clamped between the arc-shaped groove and the arc-shaped protrusion 2221. By setting the arc-shaped protrusion 2221 and the arc-shaped groove, the fixing tightness of the fixing block 22 and the measuring rope 13 can be increased.

[0038] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the utility model is explained in detail: when in use, when the water level rises or falls, the float 14 rises or falls accordingly. Under the action of the counterweight 15, the measuring rope 13 can always remain in a straightened state, and the water level value can be obtained by the indication of the measuring rope 13 at a fixed height; at the same time, when the measuring rope 13 rises or falls, it drives the fixed block 22 to rise or fall. When the fixed block 22 moves with the measuring rope 13 to contact the lifting member 21, the subsequent measuring rope 13 continues to rise, which drives the lifting member 21 to rise. When the lifting member 21 rises to contact the contact of the micro switch 23, the alarm 24 sounds an alarm, thereby reminding the staff to take corresponding measures. Through this device, an automatic alarm can be sounded when the water level reaches the preset water level. The staff does not need to pay attention to the water level all the time, which can reduce the workload of the staff and avoid missed reports.

[0039] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
