[0017] Compared with the prior art, the invention has the following beneficial effects: the remote information collection alarm for flood control has the following advantages:

[0018] 1. Before use, install the column on the bank of the river or reservoir, and make the liquid level sensor above the water surface. Then the liquid level sensor can convert the water level information into an electrical signal and transmit it to the controller. Then the controller transmits the water level information to the server of the flood control information platform through the GPRS data transmitter. When the water level is greater than the preset depth, the server of the flood control information platform will send an alarm message to the device terminal. At the same time, the controller controls the sound and light integrated alarm to sound an alarm, reminding the surrounding people to pay attention to the flood situation in time, ensuring that the surrounding personnel can make flood control preparations in time. It can use solar energy to generate electricity, and can also transmit remote data wirelessly for remote alarm. At the same time, cables do not need to be laid over long distances to avoid accidental damage and breakage of cables, ensuring the safety and convenience of information transmission.

[0019] 2. When it is necessary to maintain the upper parts during use, the hexagonal column can be rotated by using the sleeve. The hexagonal column drives the worm to rotate, and the worm will drive the lead screw nut to rotate through the worm gear. Since the lower end of the lead screw is slidably connected to the sliding strip on the inner wall of the column through the baffle, the lead screw will not rotate. Therefore, the lead screw will drive the wire rope pulley to move downward through the circular plate, and then the wire rope pulley drives the middle part of the wire rope to move downward, and then the upper right end of the wire rope drives the sliding sleeve to move upward, and then the hexagonal column is rotated in the opposite direction, and then the sliding sleeve slides downward along the column under the guidance of the pulley due to gravity, and then the sliding sleeve drives the cross bar to move downward, and at the same time, the cross bar drives the sound and light integrated alarm, solar panel, liquid level sensor and protection box to move downward, and the protection box will drive the internal battery, GPRS data transmitter, controller and solar charging controller to move downward. After moving downward, the upper parts can be easily inspected and repaired. When the liquid level sensor needs to be repaired When the device is inspected and maintained, the hand screw can be loosened, and then the hand screw will not limit the rotation of the cross bar, and then the cross bar can be rotated, so that the liquid level sensor can be moved away from above the water surface, and then the liquid level sensor can be inspected and maintained, and in the process of the cross bar moving down, the circular plate will move up to compress the spring, and then the spring will convert and store the gravitational potential energy of the cross bar and the components above it. After maintenance, the cross bar is reset and locked with the hand screw, and then the cross bar is controlled to move up. When the cross bar rises, the spring will gradually extend to provide power, so as to facilitate the control of the upward movement of the cross bar. The gravity of the cross bar is greater than the maximum elastic force of the spring. The upper components can be driven downward by the drive of the lower unit, thereby ensuring the convenience of maintenance, and it can also be rotated at the same time to avoid maintenance above the water surface, so that the maintenance safety is high, and the spring is used to store force, which is simple and labor-saving to use.

[0020] 3. As the crossbar moves upward, the positioning column gradually contacts the hook plate and drives it to rotate counterclockwise. When the positioning column moves to the middle groove of the hook plate, the hook plate is reset by gravity, and then the positioning column moves downward, and then the positioning column is moved to the inside of the hook plate, and then the crossbar is prevented from sliding downward. At the same time, during use, the wire rope is in a straight state and squeezes the card plate, and the card plate squeezes the spring sheet. The lower end of the card plate is separated from the column, and the spring sheet undergoes elastic deformation. When the wire rope breaks accidentally, the spring sheet The spring will bounce the lower end of the card plate, and then the lower end of the card plate will be in close contact with the outer arc surface of the column. When the wire rope breaks and the sliding sleeve moves down, the sliding sleeve will drive the card plate to move downward through the support seat. When the position of the card plate and the slot corresponds, the card plate will be inserted into the inside of the slot, thereby limiting the falling of the cross bar and ensuring safety during use. After moving up into place, it can be locked by a hook plate. At the same time, a safety component is also provided. After the wire rope breaks, it can be automatically connected with the slot of the column, thereby having high safety in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The working principle of the remote information collection alarm for flood control provided by the present invention is as follows: before use, the column 1 is installed on the bank of the river or reservoir, and the liquid level sensor 11 is located above the water surface, so that the liquid level sensor 11 can convert the water level information into an electrical signal and transmit it to the controller 15, and then the controller 15 transmits the water level information to the server of the flood control information platform through the GPRS data transmitter 14. When the water level is greater than the preset depth, the server of the flood control information platform will send an alarm message to the device terminal, and at the same time, the controller 15 controls the sound and light integrated alarm 12 to sound an alarm, prompting the surrounding people to pay attention to the flood situation in time, and ensure that the surrounding personnel can make flood control preparations in time. During use, the upper parts need to be When the parts are maintained, the hexagonal column 7 can be rotated by using the sleeve, and the hexagonal column 7 drives the worm 6 to rotate, and the worm 6 will drive the screw nut 42 to rotate through the worm gear 5. Since the lower end of the screw 43 is slidably connected with the sliding bar on the inner wall of the column 1 through the baffle, the screw 43 will not rotate. Therefore, the screw 43 will drive the wire rope wheel 46 to move downward through the circular plate 44, and then the wire rope wheel 46 drives the middle part of the wire rope 45 to move downward, and then the upper right end of the wire rope 45 drives the sliding sleeve 2 to move upward, and then the sliding sleeve 2 drives the cross bar 3 to move upward, and then the cross bar 3 drives the positioning column 22 to move upward, and then the positioning column 22 will move the upper end of the hook plate 21 and drive it to rotate clockwise, and then the positioning column 22 will gradually move to the top of the hook plate 21 and separate from it. , then the hook plate 21 rotates counterclockwise due to gravity to reset, and then the hexagonal column 7 rotates in the opposite direction, and then the sleeve 2 slides downward along the column 1 under the guidance of the pulley 23 due to gravity, and then the sleeve 2 drives the cross bar 3 to move downward, and the cross bar 3 drives the positioning column 22 to move downward, and then the positioning column 22 contacts the upper end of the hook plate 21 and drives it to rotate counterclockwise, and then the positioning column 22 will pass over the hook plate 21, and the hook plate 21 will not limit the movement of the cross bar 3 through the positioning column 22, and at the same time the cross bar 3 drives the sound and light integrated alarm 12, the solar panel 13, the liquid level sensor 11 and the protection box 10 to move downward, and the protection box 10 will drive the internal battery 16, the GPRS data transmitter 14, the controller 15 and the solar charging controller 17 to move downward, After moving down, the upper parts can be easily inspected and maintained.

After maintenance, the cross bar 3 is reset and locked with the hand screw 18, and then the cross bar 3 is controlled to move up. When the cross bar 3 rises, the spring 8 will gradually stretch to provide power, thereby facilitating the control of the upward movement of the cross bar 3.The gravity of the cross bar 3 is greater than the maximum elastic force of the spring 8. As the cross bar 3 moves upward, the positioning column 22 gradually contacts the hook plate 21 and drives it to rotate counterclockwise. When the positioning column 22 moves to the middle groove of the hook plate 21, the hook plate 21 is reset by gravity, and then the positioning column 22 moves downward, and then the positioning column 22 is moved to the inside of the hook plate 21, and then the cross bar 3 is prevented from sliding downward. At the same time, during use, the steel wire rope 45 is in a straight state and squeezes the card plate 25, and the card plate 25 squeezes the spring sheet 26, and the card plate 25 The lower end of the card plate 25 is in a state of being separated from the column 1, and the spring sheet 26 undergoes elastic deformation. When the wire rope 45 breaks unexpectedly, the spring sheet 26 will bounce the lower end of the card plate 25, and then the lower end of the card plate 25 will be closely in contact with the outer arc surface of the column 1. Then, when the wire rope 45 breaks and the sliding sleeve 2 moves down, the sliding sleeve 2 will drive the card plate 25 to move downward through the support seat 24. When the position of the card plate 25 corresponds to the position of the card slot 27, the card plate 25 will be inserted into the inside of the card slot 27, thereby limiting the falling of the cross bar 3 and ensuring safety during use.
