[0034] Referring to Figures 1 to 7 as shown, the present invention discloses a water gate pump station water conservancy monitoring device, including an outer box body 1 and an inner box body 2. The inner box body 2 is coaxially installed inside the outer box body 1, and a monitoring device 3 is installed in the inner box body 2. A cross-shaped outer track 101 is provided around the outer box body 1 for the monitoring device 3 to pass through and slide up and down to indicate the water level height; a water level scale line is also provided on the side surface of the outer box body 1;

[0035] Inner tracks 201 are provided around the inner box body 2 corresponding to the outer tracks 101, and a plurality of water inlets 202 are provided around the bottom end of the inner box body 2. A flow blocking plate 203 is provided with an outward opening outside the water inlet 202. Both sides of the flow blocking plate 203 are installed on the inner box body 2 through damping members 204. Specifically, the damping member 204 includes a sleeve 2041 and a guide rod 2043 slidably inserted therein. A piston 2042 is provided inside the sleeve 2041. The guide rod 2043 is connected to the piston 2042, and a damping spring 2044 is installed between one side of the piston 2042 and the inner wall of the sleeve 2041. The sleeve on the other side of the piston is filled with a non-Newtonian fluid material. When the water flow turbulently impacts, the flow blocking plate 203 will unload the impact force and act on the piston 2042. When the piston 2042 squeezes the non-Newtonian fluid material, work can be done to consume the impact force, thereby reducing the impact on the buoyancy base 301.

[0036] The monitoring device 3 includes a buoyancy base 301 provided in the inner box body 2. Two support rods 302 are installed on the top of the buoyancy base 301. A measurement base 303 is installed on the top of the support rods 302. A central shaft 206 is installed at the center of the inner box body 2. Both the buoyancy base 301 and the measurement base 303 are sleeved on the central shaft 206. A number of positioning shafts 205 are also provided around the central shaft 206.

By means of the measurement box 307 and the water level scale line provided on the side of the outer box body, the water level value can be clearly obtained. A balance plate 305 is installed below the end of the arm 304 extending outside the outer box body 1. Lifting rods 306 are installed through both sides of the balance plate 305. The measurement box 307 is fixed at the bottom of the two lifting rods 306, and a monitoring camera 308 and a lighting lamp are installed in the measurement box 307.

[0037] Refer to Figure 2 、 3As shown in the figure, two support springs 311 are installed on the top of the measurement base 303.

An elastic metal sheet 3165 is arranged between the end of the movable electrode 3164 and the corresponding electrode seat 3162 on one side. The fixed electrode 3163 is fixedly connected to the other electrode seat 3162. When the water level rises, the permanent magnet 314 approaches the alarm switch, and it will attract the movable electrode 3164 to stick to the fixed electrode 3163, thus turning on the alarm to remind the staff to pay attention.

[0038] Refer to Figure 3 、 7 As shown in the figure, a vertical plate 315 is slidably installed in the outer box body 1. The alarm switch 316 is installed at the bottom end of the vertical plate 315. A rack 317 is arranged on one side of the vertical plate 315. A regulating gear 318 is engaged with the rack 317. And a servo motor 318 is installed in the outer box body 1 to drive the regulating rack 317. And the height of the vertical plate 317 and the alarm switch 316 can also be adjusted through the cooperation of the regulating gear 318 and the rack 317, so that the water level of the alarm can be controlled and adjusted according to the adaptability of different flood seasons.

[0039] Refer to Figure 3 、 7 As shown in the figure, two pressing tracks 319 are opened on the vertical plate 315. A positioning seat 323 is installed on the inner wall of the outer box body 1.

Through the cooperation of the rollers 321 and the pressing tracks 319, the vertical plate 315 can be limited to ensure the stability of the vertical plate 315 when sliding.

[0040] Embodiment 2

[0041] Refer to Figure 1 、 2As shown in Figures 3, on the basis of the first embodiment, it is also possible to detect the amplitude of the water surface waves and the water surface wind direction. A pressure sensor 309 is installed at the top of the outer end of the outrigger 304. The pressure sensor 309 is arranged above the lifting rod 306. A pressure spring 310 is installed between the top of the lifting rod 306 and the pressure sensor 309. Through the cooperation of the pressure spring 310 and the pressure sensor 309, it is also possible to detect the amplitude of the water surface waves and the water surface wind direction. The two outriggers 304 extend to both sides of the outer box body 1. When the waves come from one side, the pressure sensor 309 on the closer side will first feel the pressure fluctuations, and calculate the wave amplitude through the magnitude and fluctuations of the pressure.

[0042] All standard parts used in the present invention can be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0043] The implementation principle of the water gate pumping station water conservancy monitoring device in the first embodiment of the present invention is as follows: During the use of the device, when the water level changes, the water flow enters the chamber through the water inlet 202 at the bottom of the inner box body 2 and pushes the buoyancy base 301 to rise or fall. The buoyancy base 301 drives the measuring base 303 to move stably along the central axis 206 and the positioning axis 205 through the support rod 302; at the same time, the outriggers 304 are lifted and lowered synchronously along the inner track 201 and the outer track 101 to align the measuring box 307 with the water level scale line for intuitive reading;

[0044] And to cope with the turbulent interference, through the coordinated cooperation of the flow blocking plate 203 and the damping member 204, when the flow blocking plate 203 is affected by the water flow, it drives the guide rod 2043 to compress the non-Newtonian fluid material to consume kinetic energy;

[0045] When the water level rises to the warning line, the buoyancy base 301 drives the permanent magnet 314 to approach the alarm switch 316, causing the movable electrode 3164 to stick to the fixed electrode 3163, turning on the circuit to trigger the alarm, and by adjusting the cooperation of the adjusting gear 318 and the rack 317, the height of the vertical plate 317 and the alarm switch 316 can also be adjusted, so that the water level for alarm can be controlled and adjusted according to the adaptability of different flood seasons;

[0046] In addition, through the cooperation of the pressure spring 310 and the pressure sensor 309, it is also possible to detect the amplitude of the water surface waves and the water surface wind direction. The two outriggers 304 extend to both sides of the outer box body 1. When the waves come from one side, the pressure sensor 309 on the closer side will first feel the pressure fluctuations, and calculate the wave amplitude through the magnitude and fluctuations of the pressure.
