Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy monitoring device for water conservancy projects. Background Technology
[0002] Water conservancy monitoring equipment is mainly used to monitor the water conservancy operation of rivers, lakes, and reservoirs, and to promptly reflect the hydrological characteristics of each body of water so that relevant departments can make arrangements to prevent floods and other disasters. Through various detectors, it detects digital information such as temperature, humidity, wind speed, wind direction, rainfall, water quality, water flow velocity, water volume, and video images or pictures of the water conservancy system.
[0003] According to the search, Chinese patent number CN218097803U discloses a water conservancy monitoring device for water conservancy projects, including a monitoring box with a detector installed. A buoyancy device is fixedly connected to the lower surface of the monitoring box. The buoyancy device includes a buoyancy cylinder and a water inlet pipe. The buoyancy cylinder is a hollow and sealed cylindrical shape.
[0004] The aforementioned public documents state that when the equipment is lowered to the bottom of the water, it is mainly through the unfolding of the contraction tube and the suction tube to absorb water and increase the counterweight. However, in actual use, even when the contraction tube and the suction tube are in a coiled state, there is still a certain amount of air inside them. Therefore, when the contraction tube is unfolded, the air inside it will affect the entry of external water through the suction tube, thus affecting the water intake and reducing the effect of absorbing water and increasing the counterweight. This is not conducive to the rapid sinking and floating of the equipment.
[0005] To address the aforementioned problems, this application proposes a water conservancy monitoring device for water conservancy projects. Utility Model Content

A push plate is fixedly connected to the end of the piston rods of the multiple electric push rods. A first connecting pipe is connected through the push plate.

[0013] Compared with related technologies, the water conservancy monitoring equipment for water conservancy projects provided by this utility model has the following beneficial effects:
[0014] By installing a float at the bottom of the monitoring box, high-pressure air is injected into the high-pressure air chamber inside the float. When the equipment needs to sink to the bottom, water is simply drawn into the counterweight chamber, which reduces the buoyancy of the equipment while increasing the counterweight, allowing it to sink quickly to the bottom. When it is necessary to float up and retrieve the equipment, the water in the counterweight chamber is simply discharged, and the high-pressure air in the high-pressure air chamber is introduced into the counterweight chamber and the annular airbag, which rapidly increases the overall buoyancy of the equipment, allowing it to float up quickly for retrieval. Overall, it is very convenient to use. Attached Figure Description

[0021] Please see Figure 1-5 The technical solution provided by this utility model specifically includes the following embodiments:
[0022] Example 1: A water conservancy monitoring device for a water conservancy project includes a monitoring box 1. A float 2 is fixedly connected to the bottom of the monitoring box 1. A partition 7 is fixedly connected inside the float 2, dividing the inside of the float 2 into a high-pressure air chamber 8 and a counterweight chamber 9 distributed vertically. A multi-section electric push rod 11 is fixedly connected to the top of the partition 7, and the piston rod of the multi-section electric push rod 11 extends into the counterweight chamber 9. A push plate 12 is fixedly connected to the end of the piston rod of the multi-section electric push rod 11. A first connecting pipe 14 is connected through the push plate 12. A second solenoid valve 15 and a one-way valve 16 distributed vertically are installed on the first connecting pipe 14. An exhaust hose 17 is fixedly connected to the bottom of the first connecting pipe 14, and the end of the exhaust hose 17 extends to one side of the float 2. A large hole 20 is opened at the bottom of the float 2. A second connecting pipe 21 is connected through the partition 7, and a third solenoid valve 22 is installed on the second connecting pipe 21.
[0023] A protective cover 10 is fixedly connected to the top of the partition 7. The multi-section electric push rod 11 is located inside the protective cover 10. The protective cover 10 can protect the multi-section electric push rod 11 inside from the high-pressure gas in the high-pressure air chamber 8.
[0024] The outer end of the float 2 is provided with a plurality of small holes 19. The small holes 19 are located below the push plate 12. When the equipment is initially launched into the water, some water will enter the counterweight cavity 9 through the large hole 20. At this time, the air in the counterweight cavity 9 located below the push plate 12 can be discharged through the small holes 19. After the equipment is fully submerged in the water, water can enter the counterweight cavity 9 together through the large hole 20 and the small holes 19.
[0025] A sealing ring 13 is fixedly connected to the outer end of the push plate 12. The outer end of the sealing ring 13 contacts the inner wall of the float 2. The sealing ring 13 can improve the sealing between the push plate 12 and the inner wall of the float 2, and prevent water from seeping into the push plate 12 and affecting the buoyancy.
[0026] A limiting ring 18 is fixedly connected to the inner wall of the float 2. The limiting ring 18 is located between the push plate 12 and the small hole 19. The limiting ring 18 can limit the maximum downward movement of the push plate 12, and prevent the push plate 12 from moving too far downward, causing water to enter the space above the push plate 12 from the small hole 19.
[0027] In the second embodiment, an annular groove 3 is provided at the top of the outer end of the float 2. An annular airbag 4 is fixedly connected inside the annular groove 3. An inflation pipe 5 is fixedly connected to the inner side of the annular airbag 4. The inflation pipe 5 passes through the float 2 and extends into the high-pressure air chamber 8. The annular airbag 4 is connected to the inside of the high-pressure air chamber 8 through the inflation pipe 5. A first solenoid valve 6 is installed on the inflation pipe 5. When the equipment floats, in addition to draining the water in the counterweight chamber 9 and injecting air, air can also be injected into the annular airbag 4 to inflate it, thereby maximizing the buoyancy of the equipment and enabling the equipment to quickly float to the surface for easy retrieval.
[0028] Working principle:
[0029] When the monitoring box 1 needs to be submerged to the bottom of the water for hydraulic monitoring, the push plate 12 can be moved upward by pulling the multi-section electric push rod 11. During this process, the second solenoid valve 15 is opened, allowing the air between the partition 7 and the push plate 12 in the counterweight chamber 9 to be discharged through the first connecting pipe 14 and the exhaust hose 17. This allows the push plate 12 to move upward normally without resistance. As the push plate 12 moves upward, water outside the float 2 can enter the counterweight chamber 9 through the large hole 20 and the small hole 19 until the counterweight chamber 9 is filled with water. Then, the second solenoid valve 15 is closed, and the entire device can sink to the bottom of the water due to its own weight. When it is necessary to retrieve the equipment, the first solenoid valve 6 and the third solenoid valve 22 are opened, and then the push plate 12 is pushed down by the multi-section electric push rod 11. After the first solenoid valve 6 is opened, the high-pressure air inside the high-pressure air chamber 8 can enter the annular air bladder 4 through the air inflator 5, causing the annular air bladder 4 to expand and increase buoyancy. When the push plate 12 is pushed down, the water in the counterweight chamber 9 is discharged while the high-pressure air inside the high-pressure air chamber 8 is introduced into the counterweight chamber 9 through the second connecting pipe 21 to further increase buoyancy. At this time, due to the large overall buoyancy of the equipment, the equipment can be floated from the bottom of the water to the surface for retrieval.
