Description

Technical Field

[0001] This application relates to the technical field of dam water level monitoring, and specifically to a water level monitoring device for a hydropower station dam. Background Art

[0002] A hydropower station, whose full name is a hydroelectric power plant, is a factory that converts the potential energy and kinetic energy of water into electrical energy. Water level monitoring includes riverbed changes, flow trends, flow directions, flood diversion, ice conditions, aquatic plants, waves, wind directions, wind forces, water surface undulation, water temperature, and other factors affecting water level changes. When necessary, the water surface slope is also measured.

[0003] When the existing monitoring equipment is monitoring, it generally directly detects the water level of the hydropower station dam through a water level sensor. The water level sensor is fixed on both sides of the hydropower station dam. However, when the water level sensor monitors the water level for a long time, it is easily corroded and damaged by sundries or silt in the water. Moreover, directly monitoring through the water level sensor easily leads to inaccurate water level monitoring, affecting the results of the water level monitoring of the hydropower station dam.

[0004] Therefore, there is an urgent need for a water level monitoring device for a hydropower station dam to solve the problem that the monitoring equipment is easily corroded and damaged by sundries or silt in the water. Utility Model Content

[0005] In view of the deficiencies of the prior art, this application provides a water level monitoring device for a hydropower station dam, which has the advantage of safely protecting the monitoring equipment and solves the problem that the monitoring equipment is easily corroded and damaged by sundries or silt in the water.

[0006] To achieve the above object, this application provides the following technical solution: A water level monitoring device for a hydropower station dam includes a support box and a fixing plate. Both ends of the fixing plate are welded to the inner sides of two groups of support boxes. An adjusting mechanism and a monitoring mechanism are arranged on the front surface of the support box;

[0007] The monitoring mechanism includes a monitoring cylinder, a water level sensor, a measuring rod, and a filter screen. The water level sensor is installed on the inner top wall of the monitoring cylinder. The measuring rod is installed at the middle position on the top of the monitoring cylinder. The filter screen is installed in the slots on the outer side and bottom of the monitoring cylinder.

[0008] When the monitoring cylinder moves downward, the water level sensor is inserted into the water of the hydropower station dam to monitor the water level, thereby measuring the height of the water level. At the same time, when the water level sensor senses the hydraulic pressure, the water level sensor transmits the signal to the display device. The staff can read the readings on the measuring rod, so as to manually monitor the water level of the hydropower station dam, reduce the interference of the external environment, and improve the accuracy of water level monitoring by simultaneously monitoring the water level manually and with the water level sensor.

[0009] Preferably, a square notch adapted to the filter screen is provided on the outer side of the monitoring cylinder.

[0010] Preferably, the measuring rod is connected to the monitoring cylinder by screws.

[0011] Preferably, the adjusting mechanism includes a driving motor, a threaded rod, a threaded seat and a support plate. The driving motor is installed on the top of the support box. One end of the threaded rod is fixedly connected to the output end of the driving motor. The other end of the threaded rod is rotatably connected to the inner bottom wall of the support box. The threaded seat is threadedly connected to the outer surface of the threaded rod. The threaded seat is slidably connected to the inner side of the support box. The support plate is welded to the front of two groups of threaded seats.

[0012] Preferably, the support plate is connected to the monitoring cylinder by screws.

[0013] Preferably, a square notch is provided on the front of the support box.

[0014] In summary, the present application includes at least one of the following beneficial effects:

[0015] 1. For the water level monitoring device of the hydropower station dam, by adjusting the angle of the monitoring cylinder, when the monitoring cylinder moves downward, the water level sensor is inserted into the water of the hydropower station dam to monitor the water level, thereby measuring the height of the water level. At the same time, when the water level sensor senses the hydraulic pressure, the water level sensor transmits the signal to the display device. The staff can read the readings on the measuring rod, so as to manually monitor the water level of the hydropower station dam, reduce the interference of the external environment, and improve the accuracy of water level monitoring by simultaneously monitoring the water level manually and by the water level sensor.

[0016] 2. For the water level monitoring device of the hydropower station dam, after the water level sensor finishes monitoring the water level, by adjusting the heights of two groups of threaded seats, the threaded seats drive the monitoring cylinder to move upward through the support plate, so that the water level sensor inside the monitoring cylinder is separated from the water body, preventing the water level sensor from being corroded and damaged by sundries or silt in the water, thereby improving the service life of the monitoring equipment.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1-4 , a water level monitoring device for a hydropower station dam, including a support box 1 and a fixed plate 2. Both ends of the fixed plate 2 are welded to the inner sides of two groups of support boxes 1. The fixed plate 2 is fixed to the inner wall of the hydropower station dam by bolts, so that the support box 1 can be conveniently installed. An adjustment mechanism and a monitoring mechanism are arranged on the front surface of the support box 1. The adjustment mechanism can change the height of the monitoring mechanism, prevent the river water from continuously overlooking the monitoring mechanism, and improve the service life of the monitoring mechanism.

[0024] Specifically, the monitoring mechanism includes a monitoring cylinder 111, a water level sensor 112, a measuring rod 113 and a filter screen 114. The water level sensor 112 is installed on the inner top wall of the monitoring cylinder 111. The measuring rod 113 is installed at the middle position of the top of the monitoring cylinder 111. The measuring rod 113 is connected to the monitoring cylinder 111 by screws. The filter screen 114 is installed in the slots on the outer side and bottom of the monitoring cylinder 111. A square slot adapted to the filter screen 114 is opened on the outer side of the monitoring cylinder 111.

[0025] Through the above technical solutions, when the monitoring mechanism moves to the lowest position to monitor the water level inside the hydropower station dam, the water level sensor 112 transmits the water pressure to the terminal, and the water level height is calculated. At the same time, when the water level sensor 112 starts to transmit data, the movement of the monitoring cylinder 111 stops. The staff can read the height shown on the measuring rod 113. By subtracting the height shown on the measuring rod 113 from the height of the dam, the water level height is read. By monitoring the water level manually and by the water level sensor 112 at the same time, the accuracy of water level monitoring is improved; the filter screen 114 filters the sundries in the water to prevent the sundries from corroding and damaging the water level sensor 112, thereby improving the service life of the monitoring device.

[0026] Specifically, the adjusting mechanism includes a driving motor 211, a threaded rod 212, a threaded seat 213 and a support plate 214. The driving motor 211 is installed on the top of the support box 1. A square notch is formed on the front of the support box 1. One end of the threaded rod 212 is fixedly connected to the output end of the driving motor 211, and the other end of the threaded rod 212 is rotatably connected to the inner bottom wall of the support box 1. The threaded seat 213 is threadedly connected to the outer surface of the threaded rod 212. The threaded seat 213 is slidably connected to the inside of the support box 1. The support plate 214 is welded to the front of the two threaded seats 213. The support plate 214 is connected to the monitoring cylinder 111 by screws.

[0027] Through the above technical solution, when the monitoring device is installed inside the dam of the hydropower station, the driving motor 211 is started. The driving motor 211 drives the threaded rod 212 to rotate. When the threaded rod 212 rotates, it drives the support plate 214 to move up and down through the threaded seat 213. The threaded seat 213 drives the monitoring cylinder 111 to move up through the support plate 214, so that the water level sensor 112 inside the monitoring cylinder 111 is separated from the water body, preventing sundries or silt in the water from corroding and damaging the water level sensor 112, thereby improving the service life of the monitoring equipment.

[0028] During use, when the monitoring cylinder 111 moves downward, the water level sensor 112 is inserted into the water of the dam of the hydropower station to monitor the water level, thereby measuring the height of the water level. At the same time, when the water level sensor 112 senses the hydraulic pressure, the water level sensor 112 transmits the signal to the display device. The staff can read the readings on the measuring rod 113, so as to manually monitor the water level of the dam of the hydropower station, reduce the interference of the external environment, and improve the accuracy of water level monitoring by manually and the water level sensor 112 monitoring the water level at the same time.

[0029] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
