Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level measurement, in particular to a water gauge identification auxiliary device with a cleaning function. Background Art

[0002] Water level measurement is a very important and most widely used item in hydrological surveys. The main water level measurement methods include manual reading method and unmanned automatic measuring station.

[0003] The manual reading method requires observers to reach the vicinity of the water gauge and observe with the naked eye. This method requires a large amount of manpower for manual observation, and it is difficult to achieve accurate and consistent observation time. At the same time, it is impossible to reach the vicinity of the water gauge for manual observation during flood seasons and natural disasters. Unmanned automatic measuring stations can effectively solve the problem of saving manpower and controllable observation time. However, this method is not intuitive and requires regular manual calibration.

[0004] With the rapid development of network technology, artificial intelligence, imaging technology, and edge computing, the technology of remote unattended automatic observation using imaging technology has developed rapidly. This can form automatic timed measurements to form test data, and images can be sent back at regular intervals, which can be remotely manually and automatically verified, effectively solving the problems of the above two methods; however, in summer, various microorganisms and plants are prone to grow in river water bodies and attach to the water gauge, causing water gauge pollution, making direct reading impossible, and artificial intelligence recognition is also difficult. Utility Model Content

[0005] In response to the problems existing in the background technology, the utility model provides a water gauge identification auxiliary device with a cleaning function. The technical solution includes: an electric winch, a water gauge frame, a water gauge, a steel cable, a longitudinal roller, a camera bracket, a transverse roller, a lifting vehicle, and a camera. The vertically arranged water gauge is fixed to the front of the water gauge frame, the electric winch is fixed to the top of the water gauge frame, and the power output of the electric winch is connected to the lifting vehicle via a steel cable.

[0006] A water gauge frame with a rectangular cross-section passes through the central through hole of the lifting vehicle. Two longitudinal rollers and two transverse rollers are provided at the upper and lower parts of the central through hole of the lifting vehicle. The two longitudinal rollers and two transverse rollers press on the four sides of the water gauge frame from four directions; the camera is installed on the front of the water gauge frame through a camera bracket, and the camera faces the water gauge.

[0007] A water gauge cleaning piece is installed in the central through hole of the lifting vehicle through a metal spring piece, and the water gauge cleaning piece is in contact with the front face of the water gauge.

[0008] An equipment box is fixedly installed on the back side of the water level frame.

[0009] A lifting vehicle controller and a camera controller are installed inside the equipment box. The lifting vehicle controller is connected to the electric winch, and the camera controller is connected to the camera.

[0010] The camera controller and the lift truck controller are connected to the service end through a signal converter and a signal transmitter.

[0011] A water entry sensor is installed at the lower end of the lifting vehicle.

[0012] The water ingress sensor is connected to the server through a signal converter and a signal transmitter.

[0013] The camera bracket and the camera are both located on the upper part of the lifting vehicle.

[0014] A fill light is installed on the camera bracket.

[0015] The lighting direction of the fill light is the same as the focal length direction of the camera.

[0016] The beneficial effects of the present invention are:

[0017] 1. Equipped with supporting equipment for cleaning the water gauge to prevent the water gauge from being contaminated in summer, which will make it impossible to read the water gauge and affect the recognition of the water gauge data.

[0018] 2. Use a camera to collect water gauge data. At the same time, a lifting vehicle can shorten the distance between the camera and the water gauge and facilitate focusing, thereby improving recognition accuracy.

[0019] 3. Weeds and branches tend to grow quickly along the river bank, which can easily block the observation angle and affect data detection and manual verification. The utility model installs the camera on an independent bracket outside the lifting vehicle, which is far away from the water gauge, greatly reducing the interference of plant obstruction on the collected image. The camera observation angle is fixed, and after one calibration, the detection data can be guaranteed to be accurate.

[0020] 4. When the water gauge is contaminated, it can be cleaned with a water gauge cleaning sheet. No on-site cleaning is required, which saves human resources and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 It is a side view schematic diagram of an embodiment of the utility model.

[0023] Among them: 1-electric winch, 2-water gauge frame, 3-water gauge, 4-steel cable, 5-longitudinal roller, 6-camera bracket, 7-transverse roller, 8-lifting car, 9-water gauge cleaning sheet, 10-water entry sensor, 11-water surface, 12-equipment box, 13-camera. DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 The embodiment of the utility model shown includes: an electric winch 1, a water gauge frame 2, a water gauge 3, a steel cable 4, a longitudinal roller 5, a camera bracket 6, a transverse roller 7, a lifting vehicle 8, a water gauge cleaning sheet 9, a water ingress sensor 10, an equipment box 12, and a camera 13. The vertically arranged water gauge 3 is fixed to the front of the water gauge frame 2, the bottom of the electric winch 1 is fixed to the top of the water gauge frame 2, and the power output of the electric winch 1 is connected to the lifting vehicle 8 via the steel cable 4; the lower end of the lifting vehicle 8 is equipped with a water ingress sensor 10;

[0026] A water gauge frame 2, which has a rectangular cross section, passes through the central through-hole of a lifting vehicle 8. Two longitudinal rollers 5 and two transverse rollers 7 are provided above and below the central through-hole of the lifting vehicle 8. The two longitudinal rollers 5 and the two transverse rollers 7 slightly press the four sides of the water gauge frame 2, thereby allowing the lifting vehicle 8 to slide along the length of the water gauge frame 2. A camera 13 is mounted on the front of the water gauge frame 2 via a camera bracket 6, with the camera 13 facing the water gauge 3.

[0027] The water gauge cleaning piece 9 is installed in the central through hole of the lifting vehicle 8 through a metal spring. The water gauge cleaning piece 9 contacts the front of the water gauge 3. The metal spring ensures that the water gauge cleaning piece 9 can still be in close contact with the front of the water gauge 3 even when it is worn.

[0028] The equipment box 12 is fixedly mounted on the back of the water gauge frame 2 and contains a lift truck controller and a camera controller. The lift truck controller is connected to the electric winch 1 to control the lift truck's movement up and down along the water gauge frame 2. The camera controller controls the camera to start / stop capturing water level video images. The water ingress sensor 10, camera controller, and lift truck controller are connected to the server via a signal converter and signal transmitter, and the operator controls the server.

[0029] The water ingress sensor 10 sends a signal to the service end after receiving the signal. Specifically, the water ingress sensor 10 can confirm that the bottom of the lifting vehicle has entered water during cleaning, and thereby control the depth of the water ingress; the water ingress sensor 10 can also remind the monitor (operator) when the water level suddenly rises to prevent the camera from being submerged.

[0030] The camera 13 is used to collect image data of the water gauge 3 (usually collecting the part of the water gauge 3 located below the lifting vehicle 8). A fill light can be set next to the camera 13. The lighting direction of the fill light installed on the camera bracket 6 is the same as the focal length direction of the camera 13. Since the distance between the camera and the water gauge is relatively close, the fill light can achieve the expected collection effect at night at a lower power.

[0031] In this embodiment, the camera bracket 6 and the camera 13 are both located on the upper part of the lifting vehicle 8 .

[0032] During operation, when the height of the water level 11 changes or a fixed detection time (usually 5 minutes) is reached and the water gauge 3 needs to be read, the service end calls the lift controller to adjust the height of the lift 8 by rotating the electric winch 1, and then calls the camera controller to make the camera 13 start collecting images;

[0033] When the attachments on the surface of the water gauge 3 affect the reading of the water gauge 3 and the water gauge 3 needs to be cleaned, the service end calls the lift controller to lift the lift 8 so that the water gauge cleaning sheet 9 cleans the surface of the water gauge 3 in the area where the attachments are located. Since the longitudinal rollers 5 and the transverse rollers 7 lightly press on the water gauge frame 2 with a rectangular cross-section from four directions, the cleaning effect is relatively good. If the cleaning is not thorough once, the lifting process can be repeated multiple times.
