[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a water level monitoring device for water conservancy projects. Background Art

[0002] Water level monitoring is the on-site measurement of water levels in rivers, lakes and groundwater. The data from water level monitoring is closely related to human life and production. The planning, design, construction and management of water conservancy projects require water level monitoring. The construction of bridges, ports, waterways, water supply and drainage projects also requires water level monitoring. In flood control and drought relief, water level monitoring is even more important. It is the basis for hydrological forecasting and hydrological intelligence. Water level monitoring is an important basic data in the study of the relationship between water level and flow and the analysis of river sediment. Radar water level gauge, also called water level radar, is an electronic device that uses electromagnetic waves to detect targets. Its main function is to carry out water conservancy monitoring, sewage treatment and flood prevention warning. Its main measurement principle is to transmit radar pulses from the radar water level sensor antenna, the antenna receives the pulses reflected from the water surface, and records the time T. Since the propagation speed C of electromagnetic waves is a constant, the distance D to the water surface is obtained, and the degree of water level rise is specifically determined to complete the water level monitoring work;

[0003] Water level monitoring in the existing technology mostly adopts methods such as setting up radar water level meters or marking water level warning lines on the side walls of the dam body. The current method of using radar water level meters is to measure the water surface distance by transmitting and receiving microwave signals.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the present invention provides a water level monitoring device for a water conservancy project, including a river dam 1, on which a water level monitoring unit 2 is provided, wherein the water level monitoring unit 2 includes a support frame 21 fixedly connected to the top side wall of the river dam 1, and a rectangular trough box 22 is fixedly connected to the other end of the support frame 21, and an I-shaped plate 29 is provided directly below the rectangular trough box 22, and T-shaped slide grooves 2901 that can be slidably engaged with the two ends of the I-shaped plate 29 are provided in the inner walls at both ends of the river dam 1, and a group of symmetrical scales 2902 are also fixedly connected to the inner walls at both ends of the river dam 1, respectively, and a rotating stretching structure is provided in the rectangular trough box 22 for driving the I-shaped plate 29 to move in real time according to the rise of the water level, and a rotating push structure is also provided on the rotating stretching structure for sounding an alarm.

[0030] The above scheme is adopted: the water level in the river dam 1 gradually rises, and when it rises to a certain height, the water body at the high water level will be more turbulent than the water body at the low water level. Because the water body is subjected to greater pressure, the resistance to the water flow is reduced, so the flow rate will increase. At this time, the rising water body acts on the I-shaped plate 29, and the turbulent water body will drive the I-shaped plate 29 and the bottom clamping point of the T-shaped chute 2901 to disengage, and the bottom is no longer clamped and limited, and then the I-shaped plate 29 follows the gradually rising water level and performs a limited synchronous rise in the inner wall of the T-shaped chute 2901. The I-shaped plate 29 and some structures on the I-shaped plate 29 contain a certain weight that can greatly reduce the water surface fluctuation in the monitored area. The scale 2902 can indicate the rising distance of the I-shaped plate 29 in real time, which is convenient for subsequent manual naked eye observation.

[0031] The rotating and stretching structure includes a rotating rod 23 that is movably sleeved in the inner walls at both ends of the rectangular trough box 22. Torsion springs 24 are fixedly connected to the outer walls of the rods on both sides of the rotating rod 23. The other ends of the two torsion springs 24 are respectively fixedly connected to the inner walls at both ends of the rectangular trough box 22. A chain 25 is fixedly connected to the middle rod body of the rotating rod 23. A U-shaped plate frame 26 is fixedly connected to the outer wall of the bottom end of the rectangular trough box 22. The chain 25 passes through the bottom plate body of the U-shaped plate frame 26. An inner circle threaded cylinder 27 is specifically fixedly connected to the outer wall of the bottom end of the U-shaped plate frame 26. A hanging block 28 is fixedly connected to the bottom end of the chain 25. The bottom end of the hanging block 28 is fixedly connected to the outer wall of the top end of the I-shaped plate 29.

[0032] The above scheme is adopted: when the I-shaped plate 29 rises, it will also drive the hanging block 28 and the chain 25 to move upward. The chain 25 that is passively moved upward will passively rotate and wrap around the rotating rod 23 through the torsion springs 24 that have been passively deformed and twisted in advance on both sides of the rotating rod 23. The rising hanging block 28 will also synchronously drive the turntable 230 and the outer ring threaded cylinder 231 to rise.

[0033] A turntable 230 is movably sleeved on the top of the hanging block 28, and an outer circle threaded tube 231 is fixedly connected to the top of the turntable 230. Four metal ball rods 232 are fixedly connected to the outer wall of the outer circle threaded tube 231. The outer wall of the outer circle threaded tube 231 and the inner wall of the inner circle threaded tube 27 can be intermittently threadedly connected. L-shaped elastic brackets 233 are fixedly connected to the outer walls of both ends of the U-shaped plate frame 26 near the bottom, and sensors are fixedly connected to the bottom ends of the two L-shaped elastic brackets 233. Metal tube covers 234 are movably sleeved on the rod bodies of the two L-shaped elastic brackets 233 respectively, and the other ends of the four metal ball rods 232 can be intermittently fitted and connected to the outer walls of one end of the two metal tube covers 234.

[0034] It is worth noting that the L-shaped elastic bracket 233 has a certain elastic expansion and contraction capability, so that the metal club 232 can intermittently hit the metal tube cover 234.

[0035] The above scheme is adopted: when the I-shaped plate 29 rises to the warning water level, the I-shaped plate 29 simultaneously drives the outer circle threaded tube 231 to contact the inner circle threaded tube 27 on the bottom end of the U-shaped plate frame 26, and rotates and moves upward inside the inner circle threaded tube. At the same time, the rotation of the outer circle threaded tube 231 will also drive the turntable 230 and the multiple metal ball rods 232 installed on its outer wall to rotate, and then the rotating multiple metal ball rods 232 will repeatedly rotate and hit the two metal tube covers 234. The two passively hit metal tube covers 234 will immediately produce a loud noise, which is used to warn the staff. At the same time, the two metal tube covers 234 that sound will be immediately sensed by the corresponding sensors, and then transmitted to the central control room via radio signals.

[0036] An annular plate 235 is movably sleeved on the outer wall of the outer ring threaded cylinder 231 near the bottom, and elastic telescopic special-shaped rods 236 are fixedly connected to the outer walls of both ends of the annular plate 235. The elastically telescopic section of the two elastic telescopic special-shaped rods 236 is specifically a section of the rod connected to the annular plate 235. A baffle 237 is fixedly connected to the outer wall of one section of the two elastic telescopic special-shaped rods 236. The other ends of the four metal ball rods 232 are also intermittently fitted and slidably connected to the outer walls of one end of the two elastic telescopic special-shaped rods 236. Scrapers 238 are fixedly connected to the rod bodies of the other two ends of the two elastic telescopic special-shaped rods 236. The bottom ends of the two groups of scrapers 238 are respectively fitted and slidably connected to the outer walls on both sides of the top of the I-shaped plate 29.

[0037] The above scheme is adopted: when the rotating disk 230 drives the multiple metal ball rods 232 to rotate during the rotation process, it will intermittently and repeatedly fit and extend the elastic telescopic special-shaped rod 236 and the baffle 237, so that a section of the elastic telescopic special-shaped rod 236 is extended. The baffle 237 installed on the elastic telescopic special-shaped rod 236 can block the suspended matter in the water body for the structures such as the outer circle threaded tube 231 and the multiple metal ball rods 232, and the passively extended elastic telescopic special-shaped rod 236 will also synchronously drive the connected scraper 238 to repeatedly translate on the I-shaped plate 29 to clean its surface, so as to avoid the I-shaped plate 29 from being attached to the suspended debris. The suspended debris that is not cleaned for a long time will carry the water body to increase weight, suppress the I-shaped plate 29 to follow the rise of the water level, and affect the normal upward movement of the I-shaped plate 29 due to the rise of the water level.

[0038] The working principle and use process of the present invention are as follows: the water level in the river dam 1 gradually rises, and when it rises to a certain height, the water body at the high water level is more turbulent than the water body at the low water level. At this time, the rising water body acts on the I-shaped plate 29, and the turbulent water body drives the I-shaped plate 29 and the bottom clamping point of the T-shaped slide 2901 to disengage, and the bottom is no longer clamped and limited, and then the I-shaped plate 29 follows the gradually rising water level and performs a limited synchronous rise in the inner wall of the T-shaped slide 2901. The I-shaped plate 29 and some structures on the I-shaped plate 29 contain a certain weight, which can greatly reduce the water surface fluctuation in the monitored area. The scale 2902 can mark the rising distance of the I-shaped plate 29 in real time, which is convenient for subsequent manual naked eye observation. When the I-shaped plate 29 rises, it will also drive the hanging block 28 and the chain 25 to move upward. The chain 25 that moves upward passively will pass through the torsion springs 24 installed on both sides of the rotating rod 23, and passively move on the rotating rod. 23, the chain 25 is rotated and wound on the chain 25; the rising hanging block 28 will also synchronously drive the turntable 230 and the outer circle threaded cylinder 231 to rise. When the I-shaped plate 29 rises to the warning water level, the I-shaped plate 29 simultaneously drives the outer circle threaded cylinder 231 to contact the inner circle threaded cylinder 27 on the bottom end of the U-shaped plate frame 26, and the threaded rotation and upward movement is performed inside it. At the same time, the rotation of the outer circle threaded cylinder 231 will also drive the turntable 230 and the multiple metal ball rods 232 installed on its outer wall to rotate, and then the rotating multiple metal ball rods 232 will repeatedly rotate and hit the two metal cylinder covers 234. The two passively hit metal cylinder covers 234 will immediately produce a loud noise, which is used to warn the staff. At the same time, the two metal cylinder covers 234 that sound will be immediately sensed by the corresponding sensors, and then transmitted to the central control room via radio signals. The use principle of the sensor is the existing technology and will not be repeated here.

[0039] When the rotating disk 230 drives the multiple metal ball rods 232 to rotate during the rotation process, it will intermittently and repeatedly fit the top-extending elastic telescopic special-shaped rod 236 and the baffle 237, so that a section of the elastic telescopic special-shaped rod 236 is extended, and the baffle 237 installed on the elastic telescopic special-shaped rod 236 can block the water suspended matter from other structures such as the outer circle threaded tube 231 and the multiple metal ball rods 232, and the passively extended elastic telescopic special-shaped rod 236 will also synchronously drive the connected scraper 238 to repeatedly translate on the I-shaped plate 29 to clean its surface to avoid suspended debris attached to the I-shaped plate 29. The suspended debris that is not cleaned for a long time will carry the weight of the water body, suppress the I-shaped plate 29 to follow the rise of the water level, and affect the normal upward movement of the I-shaped plate 29 due to the rise of the water level.
