Description

Technical Field

[0001] The utility model relates to the technical field of rainwater monitoring, in particular to a rainwater monitoring and management device with a water level alarm function. Background Art

[0002] In the prior art, during the rainy season, the water level of a river will continue to rise with the increase of rainfall. When the warning water level is reached, a corresponding alarm device is required to sound an alarm, thereby facilitating the monitoring and management of rainfall and taking corresponding flood discharge measures to avoid major water disasters. Based on this, the present application proposes a rainwater monitoring and management device with a water level alarm function to realize the detection and management of the river water level.

[0003] After searching, the Chinese patent application number 201820800797.7 discloses a water level monitoring device with automatic alarm function for water conservancy projects, including a fixed barrel, parallel rectangular slide grooves are opened on the relative inner walls of the fixed barrel, and rectangular sliders are slidably connected in the two rectangular slide grooves, and the same floating block is fixedly connected between the two rectangular sliders by screws, the top of the floating block is screwed with a fixed tube, and three circular holes are opened on the outer wall on the same side of the fixed tube, and the first pressure sensor, the second pressure sensor and the third pressure sensor are respectively embedded in the three circular holes.

[0004] The water level monitoring device with automatic alarm function for water conservancy projects in the above-mentioned patent has the following shortcomings: since the position of the pressure sensor installed on the fixed pipe cannot be adjusted, the float is limited to rising a specific distance before an alarm can be realized. Since the warning water levels of different fire water tanks are different, the device cannot perform adaptive water level monitoring according to different fire water tanks, resulting in the entire water level monitoring device being able to monitor the water level of fire water tanks of a certain specification only, making its scope of application relatively small.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] Embodiment 1:

[0034] A rainwater monitoring and management device with water level alarm function, in order to facilitate water level monitoring and alarm, such as Figure 1-4 As shown, it includes a monitoring and alarm unit, and the monitoring and alarm unit includes:

[0035] Bracket 1: A lifting rod 8 is slidably connected to a through hole at the bottom thereof, and a trigger plate 11 is fixed to the top of the lifting rod 8 by a pin;

[0036] Float 7: It is connected to the bottom of the lifting rod 8 through threads;

[0037] U-shaped frame 3: It is welded to the top outer wall of the bracket 1, and the side wall of the U-shaped frame 3 is provided with a slide groove 16;

[0038] Sliding block 14: Sliding block 14 is slidably connected to the inner wall of the sliding groove 16;

[0039] Connecting rod 2: It is welded to the outer wall of one side of the slider 14, and a contact switch 17 is fixed to the end of the connecting rod 2 away from the slider 14 by screws;

[0040] Alarm 15: It is fixed to the top outer wall of the U-shaped frame 3 by screws, and the alarm 15 is electrically connected to the contact switch 17;

[0041] In the initial stage, the entire device is installed on the bank of the river. The float 7 floats on the surface of the river using its own buoyancy. When the water level of the river rises due to rain, the float 7 will continue to rise under the action of the buoyancy of the river water. When the trigger plate 11 moves up and contacts the contact switch 17, the contact switch 17 triggers the alarm 15 to sound an alarm. In this way, an alarm is sounded when the water level of the river reaches the warning value.

[0042] Furthermore, a driving motor 9 is fixed to the top outer wall of the U-shaped frame 3 by bolts, and a lead screw 10 is rotatably connected between the top inner wall and the bottom inner wall of the U-shaped frame 3, and the output end of the driving motor 9 and the top of the lead screw 10 are connected by a coupling, and a nut matching the outer diameter of the lead screw 10 is embedded on the surface of the slider 14;

[0043] By providing a driving motor 9, the lead screw 10 can be driven to rotate, and the slider 14 slides under the guidance of the slide groove 16 to adjust the height of the contact switch 17. Through this setting, the maximum rising distance of the float 7 can be adjusted, and the warning water level height of the river can be flexibly adjusted. Since the warning water levels of different rivers are different, this structure makes the entire device suitable for different rivers, thereby expanding its scope of application.

[0044] Furthermore, a support plate 13 is welded to the outer wall of one side of the bracket 1, and a pin 5 is welded to the outer wall at the bottom of the support plate 13;

[0045] When the entire device needs to be fixed, the pin 5 is inserted into the riverbed to achieve fixed installation of the entire device.

[0046] Furthermore, a bent rod 12 is welded to the outer wall of the lifting rod 8, and a scale 6 is bonded to the outer wall of the bent rod 12;

[0047] The scale 6 can be provided to indicate the height of the river water level rise, so that relevant staff can observe the change of the river water level.

[0048] Working principle: During use, first insert the pin 5 into the riverbed, and then start the drive motor 9 to drive the screw 10 to rotate according to the height of the warning water level of the river. The slider 14 will slide along the slide groove 16, thereby adjusting the height of the contact switch 17 in the vertical direction. When it rains, as the water level of the river continues to rise, the float 7 continues to rise under the buoyancy of rainwater. When the trigger plate 11 and the contact switch 17 are in contact, the contact switch 17 is triggered to start. After the contact switch 17 is started, the alarm 15 sounds an alarm to remind relevant personnel that the rainfall has reached the warning value at this time.

[0049] Embodiment 2:

[0050] A rainwater monitoring and management device with water level alarm function, such as Figure 1-4 As shown, in order to effectively reduce the cost of monitoring and management; this embodiment makes the following supplements on the basis of embodiment 1: the top outer wall of the support plate 13 is fixed with a mounting frame 4 by bolts, and the outer surface of the mounting frame 4 is paved with a solar panel 18, and the bottom inner wall of the mounting frame 4 is respectively fixed with a battery 19 and an inverter 20 by bolts, and the battery 19, the inverter 20 and the solar panel 18 are electrically connected;

[0051] By providing a solar panel 18, light energy can be converted into electrical energy, and the generated direct current can be converted into alternating current through the inverter 20 and stored in the battery 19. The electrical energy stored in the battery 19 can be used to power the drive motor 9 and the alarm 15, thereby reducing the cost of use.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
