Description

Technical Field

[0001] This utility model belongs to the field of water level monitoring technology, specifically relating to a water level monitoring instrument for water conservancy projects. Background Technology

[0002] In the operation and management of water conservancy projects, water level monitoring is a key link to ensure project safety and optimize water resource allocation. Traditional water level monitoring in water conservancy projects usually relies on fixed observation stations and manual observation. This method is not only inefficient, but also limited by factors such as weather, time, and manpower, making it difficult to achieve continuous monitoring with high precision around the clock.

[0003] With the advancement of technology, although some water level monitoring instruments based on electronic sensors and automation technology have emerged on the market, the application of these instruments in water conservancy projects still faces many challenges. During water conservancy construction, water conservancy monitoring equipment often needs to be set up on the bank of adjacent water. However, due to different environments, different adjacent water locations will occur, and the positions where monitoring equipment can be fixed on the bank and the height of the water level on the bank will also be different. This makes it impossible for existing monitoring equipment with fixed height and fixed position to adapt to different usage environments, and its use is subject to certain limitations.

[0027] Mounting base 1, an extension plate 2 is slidably installed inside the mounting base 1, a support plate 3 is slidably installed at one end of the extension plate 2, a limit groove 4 is opened inside the support plate 3, a floating plate 5 is slidably installed inside the limit groove 4, and a buoyancy airbag 6 is fixedly installed on one side of the floating plate 5.

[0028] The detection structure includes an adjustment block 7 that is slidably installed inside the limiting groove 4 and a pressing column 8 that is fixedly installed on the top of the floating plate 5. The adjustment block 7 is equipped with a contact trigger switch 9. The trigger end of the contact trigger switch 9 is located at the bottom of the adjustment block 7, and the pressing column 8 is located directly below the trigger end.

[0029] An adjustment structure is set between the adjustment block 7 and the support plate 3 to control the height of the adjustment block 7 on the support plate 3.

[0030] In one embodiment of the present invention, the extension plate 2 is Z-shaped, one end of the extension plate 2 extends to the outside of the mounting base 1, and the other end of the extension plate 2 is threaded with a No. 1 bolt 10. The mounting base 1 has a plurality of No. 1 limiting holes 11 inside, and the No. 1 bolt 10 is adapted to the No. 1 limiting hole 11.

[0031] In one embodiment of this utility model, two connecting plates 12 are fixedly installed at one end of the extension plate 2. The internal threads of the two connecting plates 12 are fitted with No. 2 bolts 13. A plurality of No. 2 limiting holes 14 are opened on one side of the support plate 3. The No. 2 limiting holes 14 are adapted to the No. 2 bolts 13.

[0032] In one embodiment of this utility model, a sliding plate 15 is fixedly installed on one side of the adjusting block 7, and a sliding frame 16 is slidably installed on the outer surface of the contact trigger switch 9. A U-shaped post 17 is provided on one side of the sliding frame 16. Both ends of the U-shaped post 17 pass through the sliding frame 16 and the sliding plate 15 in sequence and extend to the outside of the sliding plate 15. The U-shaped post 17 is fixedly connected to the sliding frame 16 and slidably connected to the sliding plate 15. A spring 18 is fixedly installed between the sliding plate 15 and the sliding frame 16. A plurality of third-position limiting holes 19 are opened on one side of the support plate 3. The third-position limiting holes 19 are adapted to the two ends of the U-shaped post 17.

[0033] In one embodiment of the present invention, a component box 20 is provided on the top of the extension plate 2, and the component box 20 is electrically connected to the internal components of the contact trigger switch 9 via a cable 21.

[0034] Specifically, the component box 20 contains:

[0035] Alarm components are responsible for generating alarm information. Alarm components can be sound generators (such as buzzers), light signal generators (such as LED indicator lights), or other devices that can attract attention.

[0036] Receiving / Processing Unit: Used to receive signals from the contact trigger switch 9 and determine whether an alarm needs to be triggered based on preset logic. The receiving / processing unit can be a microcontroller, logic circuit, or other component capable of processing electrical signals;

[0037] Power management components ensure the alarm components and receiving / processing units can function properly. Power management components include batteries, voltage regulators, power converters, etc.

[0038] Cable interfaces: The component box should be equipped with corresponding cable interfaces for connecting and transmitting signals;

[0039] Protective components, including fuses, diodes, voltage regulators, etc., are used to protect the electronic components inside the component box 20 from faults such as overvoltage, overcurrent, or short circuit.

[0040] In one embodiment of this utility model, the surface of the support plate 3 is provided with scale lines 22, and the mounting base 1 is provided with mounting points 23 around its perimeter.

[0041] As can be seen from the above, when in use, the mounting base 1 is installed on the ground near the water source through the installation point 23. The extension plate 2 is moved on the mounting base 1 so that the end of the extension plate 2 extends above the water source. The first bolt 10 is rotated so that the first bolt 10 is inserted into the first limiting hole 11 to fix the position of the extension plate 2. At this time, the support plate 3 is installed at the end of the extension plate 2. The support plate 3 is moved downward so that its bottom is inserted into the bottom soil. Then the second bolt 13 inside the connecting plate 12 is rotated so that the second bolt 13 is inserted into the second limiting hole 14 to fix the position of the support plate 3, thus completing the installation of the monitoring instrument.

[0042] During use, the buoyancy airbag 6 floats on the water surface and slides the floating plate 5 inside the limiting groove 4. According to the scale line 22 set on the upper surface of the support plate 3, the water level changes in real time can be obtained. At the same time, the U-shaped column 17 can be pulled out from the third limiting hole 19. At this time, the position of the adjusting block 7 inside the limiting groove 4 can be moved to control the distance between the adjusting block 7 and the floating plate 5. When the water level rises, the buoyancy airbag 6 rises with the floating plate 5. When it rises to the position of the adjusting block 7, the trigger end of the contact trigger switch 9 contacts the pressing column 8, thereby causing the alarm component inside the component box 20 to generate an alarm message.

[0043] Example 2:

[0044] In one embodiment of this utility model, the contact trigger switch 9 in the detection structure is replaced by an infrared rangefinder. The original trigger end is removed and replaced by the transmitter end of the infrared rangefinder, which will be responsible for emitting an infrared beam for measurement.

[0045] The pressing column 8 no longer directly triggers the switch, but serves as a reference point or target for the infrared rangefinder to measure. The infrared rangefinder will measure the distance from the transmitter to the pressing column 8. A reflector or reflector plate is installed inside the pressing column 8, and the pressing column 8 serves as an external structure to protect the reflection point.

[0046] At this point, the component box may also include:

[0047] Microprocessor or control unit: Used to process measurement data from the infrared rangefinder, perform logical judgments, and control alarm components.

[0048] Interface circuit: Converts the measurement data from the infrared rangefinder into a format recognizable by the microprocessor or control system, and provides the necessary communication interface.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
