Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water level monitoring, in particular to a water conservancy river water level monitoring device. BACKGROUND

[0002] Water conservancy engineering refers to the control and allocation of natural surface water and groundwater to achieve the purpose of eliminating harm and benefiting; The water conservancy river water level monitoring device refers to an automatic monitoring and reporting device laid in the river range of the water conservancy project, which automatically collects water level data through a water level sensor, and transmits the processed data to the monitoring center in real time for flood control, disaster reduction, water resource scheduling and engineering safety monitoring. According to their different detection methods, it is also divided into water level monitoring and water level electronic needle, etc.

[0003] However, in order to more conveniently maintain the camera and radar sensor installed on the metal rod of the equipment, some existing water level monitoring stations move the metal rod installed with the camera and radar sensor to a low place through a special lifting structure, and then manually rotate the metal rod as a whole to turn it over to the top of the ground. Although this structure can more conveniently maintain the camera and radar sensor on the equipment compared to the original equipment, the overall operation process is relatively complicated, and the water level monitoring station not only has a camera and radar sensor for water level monitoring, but also has a solar panel for producing energy and a water level transmitter. In order to ensure that the metal rod can smoothly move up and down along the water level monitoring station, it is also necessary to ensure that the surface of the water level monitoring station has no any protrusions or depressions, otherwise the metal rod moving along the surface of the water level monitoring station may be stuck. However, since the existing water level monitoring station is generally directly placed in the outside for use, it may be deformed by external foreign objects, which makes the lifting structure unable to normally function, and in winter when the lake surface is frozen, the existing water level monitoring station can only detect the height of the ice layer surface and cannot monitor the correct water level data. Therefore, it does not meet the existing needs, and for this purpose, we propose a water conservancy river water level monitoring device. SUMMARY

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an integrated rotary maintenance auxiliary mechanism to drive the main body of the water level monitoring station to rotate clockwise around a pivot indirectly connected to it. As the pivot rotates, the various mechanisms on the main body of the water level monitoring station will gradually approach the ground. When the support rod fixed to the rear end of the main body of the water level monitoring station contacts the ground, all the mechanisms on the main body of the water level monitoring station will be at a height close to the ground and can be directly operated by a person.

The concave base in the above technical solution can protect the rotation position, thereby preventing foreign objects from impacting it and causing it to malfunction. At the same time, it is only necessary to ensure that the structure inside the concave base does not deform to drive the main body of the water level monitoring station to rotate. Compared with the existing lifting mechanism, which can only ensure that the main rod of the water level monitoring station does not deform to ensure that the structure functions properly, the rotary maintenance auxiliary mechanism is more reliable. 3. This invention utilizes an anti-icing mechanism to continuously stir the riverbed located below the radar sensor when winter nights arrive and the outside temperature drops below zero, before the riverbed is about to freeze. This prevents the riverbed from freezing over and making it impossible to accurately monitor the river's level. Through the above technical solution, the device can detect accurate level data even in low-temperature environments. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 7 An embodiment of the present invention provides a water level monitoring device for a river channel in a water conservancy project, comprising a water level monitoring station body 1, an integral rotating maintenance auxiliary mechanism fixedly connected to the lower end face of the water level monitoring station body 1, the integral rotating maintenance auxiliary mechanism comprising a monitoring station base rod 5 and a step-by-step driving mechanism, the lower end face of the monitoring station base rod 5 being a first inclined surface 17, a connecting base 8 being provided below the first inclined surface 17, the upper end face of the connecting base 8 being a second inclined surface 18, the second inclined surface 18 and the first inclined surface 17 being in close contact with each other, and the lower end face of the monitoring station base rod 5 near the rear end face being connected to the upper end face of the connecting base 8 near the rear end face via a rotating shaft 19; The outer surface of the connecting base 8 is provided with an annular groove 9 whose cross-sectional diameter is connected to that of the monitoring station base rod 5. The annular groove 9 is provided with a reinforcing sleeve 10, which is also fitted onto the outer surface of the monitoring station base rod 5. The progressive drive mechanism can first push the reinforcing sleeve 10 upward and then rotate the monitoring station base rod 5 clockwise around the rotating shaft 19. A mounting bracket 22 is fixed on the upper side of the outer surface of the water level monitoring station body 1. A detection camera 16 is fixedly installed on one side of the lower end face of the mounting bracket 22. A radar sensor 15 is fixedly installed on one side of the detection camera 16 on the outer surface of the water level monitoring station body 1. When it is necessary to detect the river water level, the radar sensor 15 and the detection camera 16 can be activated. The radar sensor 15 can detect the river water level data through ultrasonic waves and transmit it to the cloud, while the detection camera 16 can remotely monitor the lake surface.

[0020] The integral rotary maintenance auxiliary mechanism includes a concave base 4, and a concave groove 7 is provided in the middle of the upper surface of the concave base 4; a control panel 6 is fixedly installed on the outer surface of the main body 1 of the water level monitoring station on one side of the concave groove 7, and the integral rotary maintenance auxiliary mechanism is electrically connected to the control panel 6; the integral rotary maintenance auxiliary mechanism can be controlled through the control panel 6.

[0021] A rotary motor 11 is fixedly installed on one side inside the concave base 4. The output shaft of the rotary motor 11 is connected to a rotary shaft 12 through a coupling. A wire rope reel 13 is fixedly sleeved on the outer surface of the rotary shaft 12. A wire rope 14 is wound inside the wire rope reel 13, and the upper end face of the wire rope 14 is fixed to the bottom pole 5 of the monitoring station. A metal sleeve 20 is fixedly fitted on the outer surface of the wire rope 14 near the position of the wire rope reel 13. A cylindrical groove 23 located inside the connecting base 8 is provided on the outer side of the metal sleeve 20. The outer surface of the metal sleeve 20 is in contact with the inner wall of the cylindrical groove 23, and the metal sleeve 20 and the cylindrical groove 23 are slidably connected. An L-shaped push rod 21 is fixedly connected to both sides of the outer surface of the metal sleeve 20. The top ends of the two L-shaped push rods 21 extend to the bottom of the reinforcing sleeve 10 through the concave base 4. The top ends of the two L-shaped push rods 21 are located on the left and right sides of the bottom end of the reinforcing sleeve 10, respectively. When it is necessary to repair, replace, clean or calibrate the various mechanisms on the main body 1 of the water level monitoring station, the rotary motor 11 is started through the control panel 6 to drive the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, the wire rope reel 13 fixedly sleeved on the outer surface of the rotating shaft 12 will rotate together. At this time, the wire rope 14 wound inside it is released by rotating the wire rope reel 13. As the wire rope 14 is continuously released, the metal sleeve 20 originally sleeved on the outer surface of the wire rope 14 near the wire rope reel 13 will be continuously pushed out of the cylindrical groove 23. As the metal sleeve 20 moves upward, the L-shaped push rod 21 fixed to it will also move upward. As the L-shaped push rod 21 rises, the reinforcing sleeve 10 above it will be gradually pushed upward. When the reinforcing sleeve 10 leaves the connection point between the connecting base 8 and the monitoring station base rod 5, the monitoring station base rod 5 and the water level monitoring station body 1 fixed to its upper end will rotate clockwise around the pivot 19 near the rear end face of the monitoring station base rod 5, through the first inclined surface 17 and the second inclined surface 18 that are in contact with each other on the outer surfaces of the monitoring station base rod 5 and the connecting base 8, under the action of gravity. During the rotation of the monitoring station base rod 5, the steel wire rope 14 fixed to it will be continuously pulled. As the steel wire rope 14 is continuously released by the rotating motor 11, the angle that the monitoring station base rod 5 can rotate is greater.

[0022] Above the control panel 6 is a support rod 3 fixed to the rear end face of the main body 1 of the water level monitoring station, and a shock-absorbing rubber base is fixed to the rear end face of the support rod 3. As the main body 1 of the water level monitoring station rotates clockwise, the support rod 3 located at the rear end face of the main body 1 of the water level monitoring station will gradually approach the ground. When the shock-absorbing rubber base fixed to the outer surface of the support rod 3 contacts the ground, the top end of the main body 1 of the water level monitoring station will be supported. At this time, all the mechanisms on the main body 1 of the water level monitoring station are at a height close to the ground and can be directly operated by humans. At this time, the staff can directly perform maintenance, replacement, cleaning or calibration work on the various mechanisms on the main body 1 of the water level monitoring station on the ground. The above technical solution allows for the automatic movement of all mechanisms on the main body 1 of the water level monitoring station to a position where manual operation is possible from the ground simply by activating the rotary maintenance auxiliary mechanism, thus improving the overall convenience of the equipment. After the overall maintenance, replacement, cleaning, or calibration of the main body 1 of the water level monitoring station is completed, the rotating shaft 12 is rotated in the opposite direction by the rotating motor 11 to gradually retract the released wire rope 14. As the wire rope 14 is gradually retracted, a pulling force will be generated on the bottom pole 5 and the main body 1 of the water level monitoring station. Through this pulling force, the bottom pole 5 and the main body 1 of the water level monitoring station will gradually rotate counterclockwise. When the first inclined surface 17 on the lower end face of the bottom pole 5 is completely in contact with the second inclined surface 18 on the upper end face of the connecting base 8, and the bottom pole 5 and the main body 1 of the water level monitoring station return to an upright state, the reinforcing sleeve 10, which was originally pushed upward, will move downward under the action of the center, thereby sealing the connection between the two and supporting the bottom pole 5 to prevent it from tilting on its own.

[0023] The connecting base 8 is fixed in the middle position inside the concave groove 7, and the position where the first inclined surface 17 on the lower end face of the monitoring station base rod 5 and the second inclined surface 18 on the upper end face of the connecting base 8 are in contact with each other is located inside the concave groove 7. The rotation position of the water level monitoring station body 1 in the overall rotary maintenance auxiliary mechanism is located inside the concave groove 7 on the upper end face of the concave base 4. The concave base 4 in the above technical solution can protect the rotation position to prevent foreign objects from impacting it and causing it to malfunction. At the same time, it is only necessary to ensure that the structure inside the concave base 4 does not deform to drive the water level monitoring station body 1 to rotate. Compared with the existing lifting mechanism, which can only ensure that the structure can function normally if the main rod on the water level monitoring station body 1 is free from any deformation, the rotary maintenance auxiliary mechanism is more reliable.

[0024] An anti-icing mechanism 2 is provided on the outer side of the integral rotary maintenance auxiliary mechanism. The anti-icing mechanism 2 includes two side plates 201 and a synchronous drive mechanism. An inclined slide rail 202 is provided at an opposite position on the outer surface of each of the two side plates 201. A slider 203 is slidably mounted on one side inside the inclined slide rail 202. A metal shell 204 is fixed between the two sliders 203. An L-shaped stirring rod 211 is provided on the lower end face of the metal shell 204. The synchronous drive mechanism can synchronously drive the L-shaped stirring rod 211 to rotate around the center point of the lower end face of the metal shell 204. The synchronous drive mechanism includes a stepper motor 205. A main control module 213 is fixedly installed on one side. A temperature sensor 212 is fixedly installed on the outer surface of the metal casing 204 on one side of the main control module 213. The main control module 213 and the temperature sensor 212 are connected by a data cable. The temperature sensor 212 can monitor the ambient temperature in real time. When winter comes and the ambient temperature drops to below zero, the main control module 213, which is electrically connected to the temperature sensor 212, will automatically control the slider 203 to move along the inclined slide rail 202. As the slider 203 moves, the metal casing 204 fixed to it and the L-shaped stirring rod 211 located on the lower end of the metal casing 204 will move together and gradually approach the river.

[0025] The output shaft of the stepper motor 205 is connected to a transmission shaft 206 via a coupling. A circular plate 207 is fixedly sleeved on the outer surface of the transmission shaft 206. A ring of roller bearing posts 208 is mounted on the outer surface of the circular plate 207 via roller bearings, and the position and number of the roller bearing posts 208 correspond to the position and number of the L-shaped stirring rods 211. Gears 209 are fixedly sleeved on the outer surface of the roller bearing posts 208. A gear ring 210 fixed inside the metal housing 204 is provided on the outer side of the multiple gears 209, and the gear ring 210 is... The roller bearing column 208 is fixed to the lower end face of the L-shaped stirring rod 211 located below it. A contact water source sensor 214 is fixedly installed on the lower side of the outer surface of the L-shaped stirring rod 211, and the L-shaped stirring rod 211 is Z-shaped. When the contact water source sensor 214 fixed on the lower side of the outer surface of the L-shaped stirring rod 211 enters the interior of the river channel and detects the water source, the main control module 213 will close the slider 203 and stop the L-shaped stirring rod 211 at the current position. When the slider 203 is closed, the stepper motor 205 will start to move. The stepper motor 205 can drive the transmission shaft 206 connected to it and the circular plate 207 fixedly sleeved on the outer surface of the transmission shaft 206 to rotate together. During the rotation of the circular plate 207, a ring of roller bearing columns 208 fixed on the outer surface of the circular plate 207 will revolve around the transmission shaft 206. During the revolution of the roller bearing column 208, the gear 209 fixed on its outer surface will roll along the inner wall of the gear ring 210. Through the gear structure between the two, the roller bearing column 208 will automatically rotate synchronously during the revolution. During the revolution and rotation of the roller bearing column 208, the L-shaped stirring rod 211 fixed to it will also rotate together. Through the continuous rotation of the L-shaped stirring rod 211, the river channel can be continuously stirred, thereby preventing the lake surface from freezing and the inability to accurately monitor the river level. The above technical solution ensures that the equipment can detect accurate level data even in low-temperature environments; By designing the L-shaped stirring rod 211 as a Z-shape, it can be ensured that when the L-shaped stirring rod 211 rotates, it can stir the river surface located between the L-shaped stirring rods 211, thereby avoiding the formation of circular ice blocks between the L-shaped stirring rods 211.
