Problems solved by technology

[0003] When watching the tide, because the location of the tide watcher is not correct or people are attracted by the tide and fail to evacuate in time, it is easy to cause injury to the tide watchers. The existing way to maintain the order of the tide watchers mainly relies on manpower, which is inefficient and easy to "leave the net". "

Embodiment 1

[0031] see Figure 1-2 A tide watching early warning device reminded by a horn, comprising a casing 10, a water pipe 11, a sounding device and a driving device.

[0032] The housing 10 is provided with a driving chamber and a piston chamber, the driving chamber is a square structure, the piston chamber is a cylindrical upper end and a square structure at the lower end, the water pipe 11 runs through the front and rear walls of the driving chamber, and the right end of the water pipe 11 extends to the detection point.

[0033] The driving device is arranged at the lower end of the driving chamber and the piston chamber, and the sounding device is arranged at the upper end of the piston chamber.

[0034] Sounding device comprises loudspeaker 13, trachea 14, intake valve 15, exhaust valve 16, piston 17 and piston rod 18, and piston cavity upper wall is provided with two apertures, and exhaust valve 16 is located in the left aperture, enters The air valve 15 is arranged in the sm...

Embodiment 2

[0039] see image 3 A tide watching warning device reminded by a horn, the side of the water pipe 11 away from the detection point is provided with a check valve 23, which can prevent the device from causing false alarms caused by backflow in the water pipe 11 when the tide recedes.

Embodiment 3

[0041] see Figure 4 A tide-watching early warning device reminded by a horn, the side of the water pipe 11 close to the detection point is provided with a water collection port 24, which can allow more water to enter the water pipe 11 when the tide comes, thereby providing sufficient power for the fan blade 12 .

[0042] When in use, the device is placed near the detection point, and the left end of the water pipe 11 is just on the detection point, and the horn 13 is fixed on the tide-watching point. The leaf 12 drives the second rotating shaft 21 to rotate, the second rotating shaft 21 drives the wheel disc 20 to rotate, the wheel disc 20 drives the first rotating shaft 19 to move up and down, the first rotating shaft 19 drives the piston rod 18 to move up and down, and the piston rod 18 drives the piston 17 to move up and down, When the piston 17 moves downward, the small hole on the right side takes in air through the intake valve 15, and when the piston 17 moves upward, ...

Abstract

The invention discloses a tide observation early warning device capable of reminding through a loudspeaker, and belongs to the field of early warning devices. The tide observation early warning device comprises a shell, a water pipe, a sound production device and a driving device, a driving cavity and a piston cavity are formed in the shell, the driving cavity is of a square structure, the piston cavity is of a structure with a cylindrical upper end and a square lower end, the diameter of fan blades is larger than that of a wheel disc, and incapability of pushing piston due to insufficient water flow speed of tide water is prevented; the length of an air pipe can be adjusted according to the distance between a detection point and a tide observation point, the air pipe can be conveniently arranged at the position close to a tide observation person, a check valve is arranged on the side, away from the detection point, of the water pipe, and the situation that when tide water returns, the tide water flows back in the water pipe, and consequently the device gives an alarm mistakenly can be prevented; and a water collecting opening is formed in one side, close to the detection point, of the water pipe, and more water can enter the water pipe when tide water surges, so that sufficient power is provided for the fan blades.

Description

technical field [0001] The invention relates to the field of early warning devices, and more specifically, relates to a tide watching early warning device reminded by a horn. Background technique [0002] The tide is a tide formed by the gravity of the celestial bodies, the centrifugal effect of the earth's rotation, and the special terrain. When the tide comes, it sounds like thunder, overwhelming mountains and seas, like a galloping horse, and it is spectacular. There has been a custom of watching tides since ancient times. [0003] When watching the tide, because the location of the tide watcher is not correct or people are attracted by the tide and fail to evacuate in time, it is easy to cause injury to the tide watchers. The existing way to maintain the order of the tide watchers mainly relies on manpower, which is inefficient and easy to "leave the net". ". Contents of the invention [0004] 1. Technical solutions [0005] In order to solve the above problems, the...
