Description

Technical Field

[0001] The utility model relates to the technical field of weather warning, in particular to an hourly precipitation warning device. Background Art

[0002] Precipitation refers to the condensation of water vapor from the atmosphere that forms on the ground. Natural phenomena such as rain, snow, dew, frost, sleet, and hail all fall under this category. It is influenced by factors such as geographic location, atmospheric circulation, and weather system conditions. It is the most fundamental link in the water cycle and a fundamental parameter in the water balance equation. Precipitation is a general term for natural phenomena such as rain, snow, dew, frost, sleet, and hail. Precipitation is the source of surface runoff and the primary source of groundwater recharge. The uneven spatial distribution and unstable temporal variation of precipitation are direct causes of floods, waterlogging, and droughts. Urbanization is a significant factor influencing precipitation.

[0003] Patent document CN218455924U discloses a short-term heavy rainfall warning device. The device comprises a water tank with an expansion port at the top and a first retaining block mounted on the tank. An early warning mechanism is mounted on the inner wall of the water tank. The mechanism comprises a solar loudspeaker mounted on the expansion port. The early warning mechanism also comprises a first fixed block mounted within the water tank, a push-button bell mounted below the first fixed block, and a limit plate connected between the first fixed blocks. A floating block is inserted into the limit plate. The device utilizes a warning mechanism and an adjustment mechanism to adjust the outlet size according to the connection plate, enabling the device to be used in situations with heavy rainfall of varying flow rates and promptly notify people to respond accordingly. A collection mechanism, in conjunction with the water tank, allows the storage tank to store and reuse rainfall.

There are two first reduction gears 305 and they are distributed at the outer end of the first transmission rod 306. The outer end of the first transmission rod 306 is movably mounted with a support movable rod 307. The first transmission rod 306 passes through the upper end of the left end of the support movable rod 307 and extends to the right end of the support movable rod 307. The support movable rod 307 is located between the two first reduction gears 305. A second reduction gear 308 is movably mounted between the first reduction gears 305.

By starting the motor 303 to rotate the motor 303, the first gear 304 is rotated to rotate the first reduction gear 305 and the second reduction gear 308 that are meshed with each other rotate at the same time. The gear rotation is reduced by combining gears of different sizes, and the speed of the motor 303 is adjusted by replacing different first reduction gears. The specifications of the wheel 305 and the second reduction gear 308 can be changed, or the number of the first reduction gear 305 and the second reduction gear 308 can be increased or decreased to change the speed of the rotating wheel 311. When the rotating wheel 311 rotates, the lever 313 at the outer end of the rotating wheel 311 also rotates accordingly. When the lever 313 contacts the arc groove 401 on the inclined plate 411, the cover 402 moves downward to overcome the force of the spring 407 and separate from the lower end of the water outlet pipe 405, so that the water in the box 1 is discharged. When the turntable continues to rotate, the lever 313 separates from the inclined plate 411. At this time, under the force of the spring 407, the cover 402 moves upward to close the water outlet pipe 405. The time from the moment the lever 313 separates from the inclined plate 411 to the moment the lever 313 contacts the inclined plate 411 again is set to one hour.During this hour, the water level in the housing 1 rises. As the water level rises, the buoyancy of the water pushes the float 206 upward. The float 206 then pushes the moving rod 205 upward. When the first and second electrodes 209 and 211 on the moving rod 205 come into contact, a circuit is established, causing the buzzer 210 to sound an alarm. The rotation of the lever 313 effectively applies force to the inclined plate 411.

[0030] The opening and closing assembly 4 includes an inclined plate 411, an arc groove 401 is fixedly provided on the upper end of the inclined plate 411, the inner end of the arc groove 401 is movably mounted on the front end of the shift rod 313, a cover 402 is fixedly installed on the front end of the inclined plate 411, a sealing ring 403 is fixedly installed on the upper end of the cover 402, a sealing groove 404 is movably mounted on the outer end of the sealing ring 403, a water outlet pipe 405 is fixedly provided on the outer end of the sealing groove 404, and the water outlet pipe 405 is fixedly connected to the lower end of the box body 1, a telescopic rod 406 is fixedly installed on the lower end of the telescopic rod 406, a spring 407 is movably mounted on the outer end of the spring 407, the upper end of the spring 407 is movably mounted on the lower end of the cover 402, and a stabilizing block 408 is movably mounted on the lower end of the spring 407. 8 is fixedly installed with a sliding rod 409, and a movable piece 410 is movably installed on the outer end of the sliding rod 409. The sliding rod 409 passes through the movable piece 410 and extends to the upper end of the movable piece 410. The rear end of the movable piece 410 is fixedly installed at the front end of the cover 402. The arc groove 401 can limit the shift rod 313 and reduce the friction between the inclined plate 411 and the shift rod 313, so that the shift rod 313 rotates more smoothly. The sealing ring 403 is made of rubber material and has a good sealing effect and fits with the inner end of the sealing groove 404. The telescopic rod 406 can effectively move the cover 402 up and down. The stabilizing block 408 can provide stability to ensure the stability of the structure. The sliding rod 409 can limit the movable piece 410 to prevent the position of the movable piece 410 from shifting.

[0031] The first electrical chip 209 is electrically connected to the buzzer 210 , and the second electrical chip 211 is electrically connected to the buzzer 210 .

[0032] Working principle: By starting the motor 303 to rotate the motor 303, the first gear 304 rotates to rotate the first reduction gear 305 and the second reduction gear 308 that mesh with each other, and the gear rotation is reduced by combining gears of different sizes. The speed of the rotating wheel 311 can be changed by adjusting the speed of the motor 303, changing the specifications of the first reduction gear 305 and the second reduction gear 308, or increasing or decreasing the number of the first reduction gear 305 and the second reduction gear 308. When the rotating wheel 311 rotates, the lever 313 at the outer end of the rotating wheel 311 also rotates. When the lever 313 contacts the arc groove 401 on the inclined plate 411, the cover 402 moves downward to overcome the force of the spring 407 and separate from the lower end of the water outlet pipe 405, so that the water in the box 1 is discharged. When the turntable continues to rotate, the lever 313 separates from the inclined plate 411. At this time, under the force of the spring 407, the cover 402 moves upward to close the water outlet pipe 405. The time from the moment the lever 313 separates from the inclined plate 411 to the moment the lever 313 contacts the inclined plate 411 again is set to one hour. During this one hour, the water level in the box 1 rises.

[0033] When the water level rises, the buoyancy of the water pushes the float 206 upward, and the float 206 pushes the moving rod 205 upward. When the first electric piece 209 on the moving rod 205 contacts the second electric piece 211, the circuit is connected, causing the buzzer 210 to sound an alarm.

[0034] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
