Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and flood prevention, in particular to a water conservancy and flood prevention early warning device. Background Art

[0002] The existing patent (Announcement No.: CN220367647U) discloses a water conservancy flood prevention early warning device, which relates to the field of water conservancy flood prevention technology, including: a support structure; a control box, the control box is arranged on the support structure, and a control module is installed inside the control box. In the process of implementing the scheme, the inventor found that the following problems in the prior art have not been well solved: since the floating plate is located in the protective tube, there must be water in the protective tube when the floating plate rises, so that there is water vapor inside the protective tube. Since the protective tube is connected to the sleeve, the water vapor will enter the sleeve when it flows upward, and the sleeve is relatively sealed.

[0022] In order to allow external air to enter the drying box 6 and to allow hot air in the sleeve 1 to be discharged, an air inlet opening 15 is opened in the middle of the top of the drying box 6, and an air outlet opening 16 is opened at the top of the sleeve 1.

[0023] In order to conveniently block the air inlet opening 15 and the air outlet opening 16 during rain and snow, and prevent rain and snow from entering the drying box 6 and the sleeve 1 through the air inlet opening 15 and the air outlet opening 16, a cylinder 17 is fixedly connected to the middle of the top surface of the connecting plate 7, and the upper end of the cylinder 17 is movably sleeved in the air inlet opening 15, and a first baffle 18 is fixedly connected to the upper end of the cylinder 17, and the first baffle 18 is adapted to the air inlet opening 15.

[0025] In order to control the signal transmission of the photoelectric sensor receiving end 4 and the photoelectric sensor transmitting end 5 to the control center, and to remotely control the operation of the motor 8, the heating wire 10, the air outlet 16, the solar panel 23 and the battery 24, the top surface of the support base 31 is fixedly connected with a control box 22, the top of the control box 22 is fixedly connected with a solar panel 23, the left side of the bottom surface of the inner wall of the control box 22 is fixedly connected with a battery 24, the battery 24 is electrically connected to the solar panel 23, and the right side of the bottom surface of the inner wall of the control box 22 is fixedly connected with a module group 25, the module group 25 is composed of a control module, a wireless module and an alarm module, and the module group 25 is electrically connected to the photoelectric sensor receiving end 4, the photoelectric sensor transmitting end 5, the motor 8, the heating wire 10, the air outlet 16, the solar panel 23 and the battery 24.

[0026] In order to filter the water entering the protective cylinder 2 and prevent the water from bringing debris into the protective cylinder 2 , a water inlet 26 is opened at the bottom of the protective cylinder 2 , and a protective filter screen is arranged in the water inlet 26 .

[0027] Working principle: When the utility model is used, the device is set on the shore through the supporting device 3, and the protective tube 2 is placed on the river surface. When the water level rises, water will enter the protective tube 2 from the water inlet 26, and the floating plate 12 will rise by buoyancy. The floating plate 12 drives the movable rod 13 to move upward, and the movable rod 13 drives the blocking block 14 to rise. When the blocking block 14 rises and falls between the receiving end 4 of the photoelectric sensor and the air inlet opening 15, it is the warning water level. At this time, the blocking block 14 blocks the light transmission between the receiving end 4 of the photoelectric sensor and the transmitting end 5 of the photoelectric sensor, and the signal is transmitted to the module group 25. The control module on the module group 25 causes the alarm module to sound an alarm and transmits the alarm signal to the control center through the wireless module. When there is water vapor in the sleeve 1 and the weather is clear, the control center sends instructions to the control module through the wireless module, and the control module controls the battery 24 to energize the heating wire 10. After the heating wire 10 is energized, it will heat the control in the drying box 6. At the same time, the battery 24 The motor 8 is powered, and the motor 8 drives the fan blades 9 to rotate. The fan blades 9 blow the air in the drying box 6 downward, so that the hot air enters the sleeve 1 and dries the inside of the sleeve 1, thereby reducing the time that the photoelectric sensor receiving end 4 and the photoelectric sensor transmitting end 5 are in the water vapor environment, and extending the service life of the photoelectric sensor receiving end 4 and the photoelectric sensor transmitting end 5. The air discharged into the sleeve 1 will flow upward and be discharged through the first baffle 18. In rainy and snowy weather, the control module on the module group 25 controls the battery 24 to power the cylinder 17, and the cylinder 17 drives the first baffle 18 to descend, so that the bottom of the first baffle 18 is inserted into the air inlet opening 15 to block the first baffle 18. At the same time, the first baffle 18 drives the second baffle 19 to descend through the connecting rod 20, so that the bottom of the second baffle 19 is inserted into the air outlet opening 16 to block the air outlet opening 16, thereby preventing rain and snow from entering the drying box 6 and the sleeve 1 from the air inlet opening 15 and the air outlet opening 16.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
