[0022] The utility model provides an audio-visual alarm device using the tidal elevation difference, such as Figure 1-4 As shown, it includes a column 1, a mounting portion 2, a lifting block 3, a plurality of floating balls 4 and a plurality of groups of trigger components.

[0023] The mounting part 2 is arranged at the bottom of the column 1 and is used to be installed at the monitoring point. The mounting part 2 is a mounting plate, and a plurality of connection holes for fixing are arranged on the mounting plate. After drilling holes at the mounting point, the mounting plate is fixed by expansion bolts. The mounting part 2 can also be an insert cone, and the installation is completed by deeply inserting the insert cone into the mounting point.

[0024] like Figure 1-2 As shown, a sliding cavity is provided in the column 1 for the vertical lifting of the lifting block 3, and a plurality of floating balls 4 are connected to the lifting block 3. In this embodiment, there are three floating balls 4, which are respectively arranged on three sides of the lifting block 3. There are three groups of trigger components, which are arranged vertically along the column 1 according to the alarm height, for example, at 0.5 meters, 1 meter, and 1.5 meters before the high tide. When the lifting block 3 rises to be flush with the corresponding trigger component, the corresponding trigger component will be triggered.

[0025] Specific as Figure 3 As shown, the trigger assembly includes a slide 5, a magnetic block 7, an electromagnet 1 8, an electromagnet 2 9, and a group of contacts 10 connected to the signal transmitter. The slide 5 is horizontally arranged on the column 1 and penetrates the inside of the column 1. The magnetic block 7 slides horizontally and fits in the slide 5. The middle part of the magnetic block 7 is made of copper. The left and right sides corresponding to the electromagnet 1 8 and the electromagnet 2 9 are magnetic bodies. The electromagnet 1 8 is arranged on the end of the slide 5 away from the column 1. The electromagnet 2 9 is arranged on the lifting block 3 and corresponds to the magnetic block 7. A group of contacts 10 are arranged at the upper and lower ends of the slide 5 next to the electromagnet 1 8 and correspond to the upper and lower ends of the magnetic block 7. When the electromagnet 1 8 and the electromagnet 2 9 are energized, the magnetic poles of the side corresponding to the magnetic block 7 are the same. When the electromagnet 1 8 adsorbs the magnetic block 7, the upper and lower surfaces of the copper body of the magnetic block 7 contact with a group of contacts 10. Under normal conditions, the electromagnet 1 8 is in a normally open state, and the electromagnet 2 9 is in a normally closed state.

[0026] Each trigger assembly also includes a trigger switch 6, which is used to turn on the electromagnet 8. The trigger switch 6 is arranged below the slideway 5 of the corresponding trigger assembly in the column 1. When the lifting block 3 passes the corresponding trigger switch 6, the switch can be triggered.

[0027] When the tide comes, the tide will drive the float 4 to link the lifting block 3 to rise. If the tide rises only for a moment and then falls, the lifting block 3 will fall accordingly and trigger the corresponding trigger switch 6, so that the contact block 10 does not turn on the signal transmitter, thereby preventing the occurrence of false alarms due to wave shaking.

[0028] The signal transmitter comprises a primary signal transmitter, a secondary signal transmitter and a tertiary signal transmitter. A group of contacts 10 on each group of trigger components are respectively connected in series to the circuits of the primary signal transmitter, the secondary signal transmitter and the tertiary signal transmitter.

[0029] like Figure 4 As shown, the device also includes a controller, a signal receiver, a first-level alarm, a second-level alarm, and a third-level alarm. The first-level signal transmitter, the second-level signal transmitter, and the third-level signal transmitter are connected to the signal receiver through electrical signals. The optical sensor composed of the signal transmitter and the signal receiver is an existing commercial product, which is used to transmit electrical signals and is a prior art, and the specific details are not repeated. The signal receiver, the first-level alarm, the second-level alarm, and the third-level alarm are all connected to the controller.

[0030] The first-level signal transmitter, the second-level signal transmitter and the third-level signal transmitter correspond to the first-level alarm, the second-level alarm and the third-level alarm respectively.

[0031] Working principle: When the tide rises to 0.5 meters, the lifting block 3 rises to the position corresponding to the first slide 5, and the electromagnet 2 9 on the lifting block 3 will drive the magnetic block 7 to slide toward the contact block 10, and turn on the first-level signal transmitter, and transmit the signal to the signal receiver. The controller controls the first-level alarm to alarm, realizing the first-level alarm of the tide. When the tide continues to rise to 1 meter, the lifting block 3 rises to the position corresponding to the second slide 5, and the electromagnet 2 9 on the lifting block 3 will drive the magnetic block 7 to slide toward the contact block 10, and turn on the second-level signal transmitter, and transmit the signal to the signal receiver. The controller controls the second-level alarm to alarm, realizing the second-level alarm of the tide. When the tide rises to 1.5 meters, the third-level signal transmitter is turned on, and the signal is transmitted to the signal receiver. The controller controls the third-level alarm to alarm, realizing the third-level alarm of the tide. When the tide recedes, the lifting block 3 moves downward. Every time the lifting block 3 passes a trigger switch 6, the trigger switch 6 will turn on the corresponding electromagnet 8, pushing the magnetic block 7 to the side close to the column 1, so that the magnetic block 7 is separated from the contact block 10, disconnecting the power supply of the signal transmitter, and the controller releases the alarm.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
