Description

Technical Field

[0001] The utility model relates to the technical field of flood control of water conservancy projects, in particular to a flood control alarm mechanism. Background Art

[0002] Flood prevention refers to the reasonable arrangement of flood forecasting, flood prevention dispatching, flood prevention projects, etc. before the flood season arrives, so as to prevent and reduce the disasters caused by floods. The flood alarm mechanism is an important equipment used in the field of flood prevention of water conservancy projects. When used, it can effectively monitor the changes in water levels, so as to promptly remind the staff to take corresponding countermeasures. However, the existing flood alarm mechanisms still have some shortcomings. For example, most of them use a single sensor for sensor monitoring. In the outdoor environment, especially in the water source area, it is exposed to the sun and rain. If a single sensor fails, it will affect the monitoring of the water level. Moreover, the existing flood alarm mechanism does not have the function of driving away birds, causing the installation platform of the flood alarm mechanism to become a natural nesting platform for birds. At the same time, as proposed in application number: CN202320770877.3, "the outer side of the support column (2) is provided with a sliding sleeve (3), and the sliding sleeve (3) is slidably matched with the support column (2)", the sliding sleeve is directly sleeved on the support column. When in use, water will seep between the two, and due to the tension of the water, the sliding sleeve and the support column are tightly adsorbed together, which makes it impossible to use normally. For this reason, we propose a flood alarm mechanism. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-2The utility model provides a technical solution: a flood prevention alarm mechanism, which is a mechanism for monitoring water levels in water conservancy projects, comprises a base 1, a square column 2 is arranged at the top center of the base 1, a top plate 3 is arranged on the top of the square column 2, distance sensors 4 are arranged at the center of the left and right sides of the bottom of the top plate 3, proximity switches 5 are arranged on the top of the left and right sides of the square column 2, a square sliding sleeve 6 is arranged at the bottom of the outer wall of the square column 2, a slide groove 8 matching the square column 2 is arranged at the center of the square sliding sleeve 6, and grooves 9 are arranged vertically around the inner cavity of the slide groove 8. The grooves 9 can prevent water from entering between the inner wall of the slide groove 8 and the outer wall of the square column 2. After that, due to the tension of water, the inner wall of the slide 8 and the outer wall of the square column 2 are closely adsorbed together, so that the square sleeve 6 cannot effectively move up and down. Floating plates 7 are arranged on the left and right sides of the square sleeve 6. When the water level changes, the water will drive the floating plates 7 to move upward through buoyancy, and the floating plates 7 will drive the square sleeve 6 to move upward on the square column 2 when moving upward. When the floating plates 7 move up to the preset position, the distance sensor 4 will detect that the distance is less than the preset value, that is, the water level reaches the warning line. At the same time, the upwardly moving square sleeve 6 will also approach the proximity switch 5 and trigger the proximity switch 5, so that the effect of double monitoring can be achieved. Fixed rods 10 are arranged around the top, and photovoltaic brackets 11 are connected to the tops of the fixed rods 10. A solar panel 12 is arranged on the top of the photovoltaic bracket 11. A battery 13 is arranged on the left side of the top of the top plate 3. The solar panel 12 is electrically connected to the battery 13. When the solar panel 12 is working, it converts light energy into electrical energy through an inverter and other equipment and stores it in the battery 13. Since it is a common technology, it will not be described in detail in this article. A wireless alarm 14 is arranged at the top center of the top plate 3. The wireless alarm 14 is electrically connected to the distance sensor 4 and the proximity switch 5 respectively. When the distance sensor 4 detects that the distance is less than the preset value, the wireless alarm 14 is set. When the value is set and the proximity switch 5 is triggered, both will transmit signals to the wireless alarm 14, and the wireless alarm 14 will transmit the alarm signal to the remote terminal to remind the staff. The wireless alarm 14 and the distance sensor 4 and the proximity switch 5 are electrically connected to the battery 13 respectively. A low-speed motor 15 is arranged at the center of the top right side of the top plate 3. The low-speed motor 15 is electrically connected to the battery 13. A motor shaft 16 is arranged on the right side of the low-speed motor 15. A bird repeller 17 is arranged on the right side of the motor shaft 16. The low-speed motor 15 can drive the bird repeller 17 to rotate through the motor shaft 16, so as to achieve the effect of repelling birds and prevent birds from nesting on the top of the top plate 3.

[0019] Among them, preferably, the inner wall of the inner cavity of the slide groove 8 is fitted and connected with the outer wall of the square column 2. This setting can increase the stability of the connection between the square column 2 and the square sliding sleeve 6 and avoid shaking. The angle between the square column 2 and the base 1 is set to ninety degrees.

[0020] Preferably, a heat insulation plate is provided at the bottom of the photovoltaic bracket 11. This arrangement allows the heat generated by the solar panel 12 during operation to affect structures such as the battery 13, thereby causing their temperature to rise and affecting their service life. The photovoltaic bracket 11 is tilted with the left side lower and the right side higher. This arrangement can prevent rainwater from accumulating on the top of the solar panel 12. The length and width of the photovoltaic bracket 11 are both greater than the length and width of the top plate 3.

[0021] Preferably, foam float blocks are arranged horizontally at the bottom of the float plate 7 in sequence from the inside to the outside, and such arrangement can increase the buoyancy of the float plate 7. Connecting blocks are arranged on both sides of one end of the float plate 7 close to the square sleeve 6, and bolts are arranged between the connecting blocks and the square sleeve 6. The bolts are used for connection, so that the float plate 7 on one side can be disassembled and replaced in time after being broken or damaged, so as to avoid affecting the accuracy of the detection.

[0022] Embodiment 2:

[0023] Reference Figure 1 This embodiment is different from the first embodiment in that: baffles are provided on the front, rear and left sides of the top of the top plate 3, and the baffles can protect the wireless alarm 14 and the battery 13 to prevent rainwater from being blown into the top of the top plate 3 from the side during heavy rain.
