[0019] Additional aspects and advantages of the application will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and drawings. BRIEF DESCRIPTION OF DRAWINGS

[0020] The above and / or additional aspects and advantages of the application will become apparent and be readily appreciated from the following description, taken in conjunction with the accompanying drawings, in which: Figure 1 A structural schematic diagram of a remote automatic cleaning device for a water gauge of a hydropower station is provided for an embodiment of the application; Figure 2 A flowchart of a remote automatic cleaning method for a water gauge of a hydropower station is provided for an embodiment of the application. DETAILED DESCRIPTION

[0021] The embodiments of the application are described in detail below, examples of which are shown in the accompanying drawings, in which the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application.

[0022] The remote automatic cleaning device and method for a water gauge of a hydropower station of the embodiments of the application are described below with reference to the accompanying drawings.

[0023] Figure 1 A structural schematic diagram of a remote automatic cleaning device for a water gauge of a hydropower station is provided for an embodiment of the application, as shown in Figure 1 The device includes a water gun 10, a variable frequency water pump 20, a servo motor 30, an industrial television 40 and a programmable logic controller (PLC) control unit 50.

[0024] The water gun 10 is located near the water level gauge in the reservoir area of ​​the hydropower station. The water gun 10 is connected to the variable frequency water pump 20 through a water supply pipe. The water gun 10 is also connected to the servo motor 30. The PLC control unit 50 establishes communication connections with the variable frequency water pump 20, the servo motor 30 and the industrial television 40 respectively.

[0025] The industrial television 40 is used to identify contamination parameters on the water level gauge and determine whether the gauge needs cleaning based on these parameters. These contamination parameters include the degree of contamination, as well as the location and type of contaminants.

[0026] The water gun 10 is used to spray high-pressure water generated by the variable frequency water pump 20 onto the water level gauge to clean it; the servo motor 30 is used to drive the water gun 10 to move and adjust its status parameters. The status parameters of the water gun 10 include the spray angle and the fine-tuned position.

[0027] The PLC control unit 50 is used to control the start and stop status of the variable frequency water pump 20 and the servo motor 30, and to send cleaning adjustment commands to the variable frequency water pump 20 and the servo motor 30.

[0028] Specifically, this application installs a high-pressure water gun system next to the water level gauge in the reservoir area. A variable frequency water pump 20 generates a high-pressure water flow, and the variable frequency motor in the pump 20 can regulate the water pressure. Before cleaning, an industrial television 40 identifies the contamination level of the water level gauge and determines whether cleaning is necessary. The PLC control unit 50 receives the signal from the industrial television 40. If cleaning is deemed unnecessary, the PLC control unit 50 controls the servo motor 30 to drive the water gun 10 to clean the water level gauge.

[0029] In the remote automated cleaning device of this application, the connection relationship of each device is as follows: the water gun 10 installed next to the water level gauge in the reservoir area is connected to the variable frequency water pump 20 through a water supply pipe, such as... Figure 1 As shown, the variable frequency water pump 20 can draw water from the forebay of the hydropower station reservoir, and the water flow is pumped from the forebay through the water pipe to the water gun 10. The PLC control unit 50 establishes communication connections with the variable frequency water pump 20, the servo motor 30 and the industrial television 40 respectively to exchange data.

[0030] The transmission path of the detection data and the control signal in the automatic cleaning process is as follows: the industrial television 40 identifies the pollution condition of the water scale in the yard, automatically judges whether cleaning is needed (for example, whether the pollution area exceeds the threshold value), and transmits the detection data and the judgment result to the PLC control unit 50. The PLC control unit 50 sends start-stop control instructions to the control servo motor 30 and the variable frequency water pump 20. The variable frequency water pump 20 can also adjust the water flow pressure according to the adjustment instructions sent by the PLC control unit 50. The servo motor 30 can drive the water gun 10 to move after being started and can adjust the state parameters of the water gun, such as the spray angle of the water gun, according to the adjustment instructions sent by the PLC control unit 50.

[0031] In an embodiment of the present application, the pollution parameter of the water scale includes a pollution degree, and the PLC control unit is specifically configured to: determine a pressure value of the high-pressure water flow generated by the variable frequency water pump according to the pollution degree, and send an adjustment instruction containing the pressure value of the high-pressure water flow to the variable frequency water pump; and the variable frequency water pump is specifically configured to adjust the water flow pressure according to the received pressure value of the high-pressure water flow.

[0032] Specifically, the embodiment adjusts the water flow pressure to adapt to the cleaning requirements of the water scale with different pollution degrees, and realizes energy-saving and efficient cleaning in cooperation with the overall operation logic of the device. The pollution degree can be determined by various parameters such as the pollution area on the water scale, the thickness of the pollutants, and the difficulty of cleaning the type of pollutants. The pressure value of the high-pressure water flow can be increased as the pollution degree increases. For example, by changing the water flow spray pressure, the different thickness of the silt pollution on the surface of the water scale can be dealt with. When the pollution degree is heavy, the pressure is increased to enhance the water flow impact force to ensure complete cleaning; when the pollution degree is light, the pressure is reduced to avoid resource waste or damage to the water scale.

[0033] Based on the above embodiment, in order to ensure the cleaning effect of the water scale, in an embodiment of the present application, the industrial television is further configured to: after the water scale is cleaned by the water gun spraying high-pressure water flow, the pollution parameter of the water scale is detected again; and the PLC control unit is specifically configured to: in the case that the pollution parameter detected by the industrial television again meets the preset requirements, the variable frequency water pump and the servo motor are controlled to stop running.

[0034] Specifically, after one round of cleaning is performed in the manner described in the above embodiment, the pollution parameter of the water scale is detected again by the industrial television 40, including re-detecting the pollution degree, re-determining the area and position of the pollutants after cleaning, and the like. Further, the PLC control unit 50 determines whether the re-detected pollution parameter meets the preset requirements, such as whether the pollution degree is reduced to zero, or compares the current pollution degree with the preset threshold value to determine whether the pollution degree reaches the allowed pollution range. In the case that the pollution parameter meets the preset requirements, the variable frequency water pump and the servo motor are controlled to stop working.

[0035] Further, in the embodiment, the PLC control unit 50 is specifically configured to: in a case where the pollution parameter re-detected by the industrial television does not meet the preset requirement, adjust the pressure value of the high-pressure water flow generated by the frequency conversion water pump and the state parameter of the water gun based on the re-detected pollution parameter, wherein the state parameter of the water gun includes the spray angle and the position of the water gun.

[0036] For example, in a case where the pollution parameter re-detected by the industrial television does not meet the preset requirement (i.e., the pollution degree is not up to standard, for example, there are still difficult-to-clean pollutants on the water scale, the thickness of the silt is still relatively thick, or there is still silt in some areas, etc.), the pressure value of the high-pressure water flow generated by the frequency conversion water pump is increased according to the position and the pollution degree of the detected pollutants, and the spray angle of the water gun is adjusted or the position of the water gun is fine-tuned according to the position of the detected pollutants. Thus, after re-cleaning the water scale, the water scale can be fully cleaned, the water pressure is increased to completely remove stubborn pollutants, and the areas where the pollutants are missed or still exist are cleaned.

[0037] In an embodiment of the present application, the industrial television is specifically configured to: receive a remote control instruction input by a user to the PLC control unit, and send the remote control instruction to the PLC control unit, so as to remotely control the frequency conversion water pump and the servo motor by the user.

[0038] Specifically, the embodiment can realize remote control of the high-pressure water gun start-stop and steering by the user in a manual mode, and realize real-time cleaning of the water scale. In specific implementation, as a possible implementation manner, the industrial television 40 is taken as a remote control terminal, the user sends a remote control instruction on a human-computer interaction device (such as a touch screen) of the industrial television 40, and then the industrial television 40 sends the control instruction to remotely manually control the PLC control unit 50.

[0039] In an embodiment of the present application, a flow regulating valve is arranged on the water supply pipe, the flow regulating valve is connected with the PLC control unit, and the PLC control unit is further configured to adjust the flow of the water in the water supply pipe by controlling the opening degree of the flow regulating valve; and a detachable nozzle is arranged on the water spraying end of the water gun, and the water spraying caliber of the nozzle corresponds to the pollution degree.

[0040] Specifically, the embodiment is provided with a flow regulating valve on the water supply pipe, the flow regulating valve is electrically connected with the PLC control unit 50, and the PLC control unit 50 can adjust the flow of the water in the water supply pipe by controlling the opening degree of the flow regulating valve. Thus, by arranging the flow regulating valve, the flow of the water can be flexibly adjusted according to the pollution degree of the water scale, so as to avoid waste of water resources while ensuring the cleaning effect.

[0041] And, the water gun 10 in the embodiment is provided with a detachable nozzle at the water spraying end, and the water spraying caliber of the nozzle can be selected and replaced according to the pollution degree of the water scale. For example, when the surface of the water scale is attached with thick silt, a small caliber nozzle can be replaced to improve the water flow impact force and enhance the cleaning effect; when the water scale is only attached with a small amount of floating dust, a large caliber nozzle can be replaced to realize large range and rapid cleaning.

[0042] In an embodiment of the present application, the industrial television comprises: a high-definition camera, which is used to collect images of the water scale; and an image recognition module, which is used to perform image recognition analysis on the images of the water scale to determine pollution parameters.

[0043] Specifically, the high-definition camera in the embodiment is used to shoot images of the water scale in the reservoir area, and the image recognition module is used to process and analyze the shot images to detect parameters such as the position and area of the pollutants and determine the pollution degree of the water scale. The high-definition camera can clearly capture the pollution condition on the surface of the water scale, and the image recognition module can accurately determine the pollution area and the pollution degree by analyzing parameters such as the gray value and color difference of the images.

[0044] For example, a pollution determination threshold is preset in the image recognition module, and when the area proportion of the pollution area of the water scale exceeds the pollution determination threshold, a cleaning signal is automatically generated and transmitted to the PLC control unit 50. For example, the pollution determination threshold can be set to 30%, and when the image recognition module detects that the area proportion of the pollution area on the surface of the water scale exceeds 30%, a cleaning signal is immediately sent to the PLC control unit 50 to start the automatic cleaning process, so that the water scale can always be in a clear observation state.

[0045] In summary, the remote automatic cleaning device for the water scale of the hydropower station in the embodiment of the present application can realize automatic identification of pollution and automatic cleaning of the water scale in the reservoir area of the hydropower station, without manual water operation, effectively reducing the safety risk; at the same time, manual intervention can be realized through the remote control terminal to meet different cleaning needs. Moreover, the device improves the cleaning efficiency of the water scale and is not limited by night and adverse weather conditions, and can be applied to different working scenes. After detecting the pollution of the water scale, the device can automatically clean in time, reducing the waiting time of the cleaning task. Therefore, the device improves the safety, timeliness and convenience of the cleaning of the water scale, and provides a strong guarantee for the dispatching work of the hydropower station.

[0046] In order to more clearly illustrate the specific implementation process of the remote automatic cleaning device of the water gauge of the hydropower station on the cleaning of the water gauge, the following will be described in detail with reference to a remote automatic cleaning method of a water gauge of a hydropower station according to an embodiment of the present application. The method is applied to the remote automatic cleaning device of the water gauge of the hydropower station in the above embodiment, that is, the cleaning method of the present embodiment is realized by controlling the device in the above embodiment. The operation device involved in the method includes various components as described in the above embodiment, which will not be described here.

[0047] Figure 2 A flow chart of a remote automatic cleaning method of a water gauge of a hydropower station according to an embodiment of the present application is shown in FIG. 8. The method includes the following steps: Figure 2 Step S101: Identify the pollution parameters of the water gauge in the reservoir area of the hydropower station through the industrial television, and determine whether the water gauge needs to be cleaned according to the pollution parameters.

[0048] Step S102: In the case that the water gauge needs to be cleaned, control the variable frequency water pump and the servo motor to start, and determine the pressure value of the high-pressure water flow generated by the variable frequency water pump and the state parameters of the water gun according to the pollution parameters.

[0049] Step S103: Adjust the water flow pressure through the variable frequency water pump according to the pressure value, and drive the water gun through the servo motor and adjust the water gun according to the state parameters.

[0050] Step S104: Spray the high-pressure water flow generated by the variable frequency water pump to the water gauge through the water gun to clean the water gauge.

[0051] In an embodiment of the present application, after spraying the high-pressure water flow generated by the variable frequency water pump to the water gauge through the water gun to clean the water gauge, it further includes: re-detecting the pollution parameters of the water gauge; in the case that the re-detected pollution parameters do not meet the preset requirements, adjusting the pressure value of the high-pressure water flow generated by the variable frequency water pump and the state parameters of the water gun based on the re-detected pollution parameters.

[0052] In order to more clearly and intuitively illustrate the implementation mode of the remote automatic cleaning method of the water gauge of the hydropower station in actual application, the following will be described with reference to several specific embodiments in actual application.

[0053] ​As a first example, the components of the automatic cleaning device are installed and connected first. The water gun is fixedly installed on one side of the water scale in the reservoir area through a support, the horizontal distance between the water gun and the water scale is reasonably set to ensure that the water flow sprayed by the water gun can cover the entire surface of the water scale; the water inlet of the water gun is connected to the water outlet of the variable frequency water pump through a water supply pipe, the water inlet of the variable frequency water pump extends to the front pool of the reservoir area through a pipeline for taking water from the front pool of the reservoir area; the high-definition camera of the industrial television is installed on the support in front of the water scale, the shooting angle of the camera is adjusted to be able to completely shoot all the scale areas of the water scale, the image recognition module of the industrial television is connected to the PLC control unit through a communication bus; the servo motor is connected to the support of the water gun through a gear transmission mechanism, the control end of the servo motor is electrically connected to the output end of the PLC control unit; the control end of the variable frequency water pump is also electrically connected to the output end of the PLC control unit.

[0054] Then, during the cleaning process, first, pollution identification is performed. The high-definition camera of the industrial television takes an image of the water scale at certain time intervals and transmits the image to the image recognition module; the image recognition module processes the image and calculates the area ratio of the polluted area on the surface of the water scale. In this embodiment, the pollution judgment threshold is set to 25%, and when the area ratio of the pollution area is detected to be more than 25%, the image recognition module generates a cleaning signal and transmits the signal to the PLC control unit.

[0055] Second, automatic cleaning is performed. After receiving the cleaning signal, the PLC control unit first controls the variable frequency water pump to start and adjusts the water flow pressure to a preset pressure value (the pressure value is determined through preliminary test and can effectively remove the silt on the surface of the water scale without damaging the water scale). Subsequently, the PLC control unit controls the servo motor to start, and the servo motor drives the water gun support to move up and down along the height direction of the water scale at a certain speed to clean the surface of the water scale comprehensively. During the cleaning process, the angle encoder on the servo motor detects the rotation angle of the motor in real time and feeds back the data to the PLC control unit, and the PLC control unit adjusts the movement of the servo motor according to the angle data to ensure that the movement track of the water gun is accurate and has no cleaning blind area.

[0056] Third, stop cleaning. After the cleaning duration reaches the set time, the high-definition camera of the industrial television takes an image of the water scale again, and the image recognition module re-detects the area ratio of the pollution area; if the area ratio of the pollution area is less than 25%, the PLC control unit controls the variable frequency water pump and the servo motor to stop running, and the cleaning is completed; if the area ratio of the pollution area is still higher than 25%, the PLC control unit increases the water flow pressure of the variable frequency water pump to 1.0 MPa and continues to clean for a certain period of time until the area ratio of the pollution area is less than 25%.

[0057] As a second example, the second example is based on the first example described above, and further includes a remote control terminal (which can be an industrial television or an industrial tablet computer, etc.) and a flow regulating valve, and other components and connection relationships are the same as those of the first example.

[0058] The second example has a remote control function. The remote control terminal is connected to the PLC control unit through a wireless communication module. The staff can view the real-time image of the water gauge transmitted by the industrial television through the remote control terminal in the central control room of the hydropower station. When a special situation occurs (such as the local area of the water gauge is severely polluted and the automatic cleaning cannot be completely removed), the staff can send a manual control instruction on the remote control terminal: adjust the water flow pressure of the frequency conversion water pump through the touch screen, set the rotation angle of the servo motor (control the water gun to aim at the severely polluted area), and control the start and stop of the water gun to realize accurate cleaning of the specific area of the water gauge.

[0059] The second example also has a flow regulating function. A flow regulating valve is installed on the water supply pipe, and the control end of the flow regulating valve is electrically connected to the PLC control unit. When the pollution degree of the water gauge is relatively light (for example, the pollution area accounts for 25%-30%), the PLC control unit controls the opening of the flow regulating valve to be 50%, reduces the water flow, and avoids waste of water resources; when the pollution degree of the water gauge is relatively heavy (the pollution area accounts for more than 30%), the PLC control unit controls the opening of the flow regulating valve to be 100%, increases the water flow, and improves the cleaning efficiency.

[0060] In summary, the remote automatic cleaning method for the water gauge of the hydropower station implemented by the present application can realize automatic identification and cleaning of the water gauge in the reservoir area of the hydropower station, without manual water operation, effectively reducing the safety risk; at the same time, manual intervention can be realized through the remote control terminal to meet different cleaning needs. Moreover, the method improves the cleaning efficiency of the water gauge and is not limited by night and adverse weather conditions, and can be applied to different working scenarios. After detecting the pollution of the water gauge, the method can automatically clean in time, reducing the waiting time of the cleaning task. Therefore, the method improves the safety, timeliness and convenience of the water gauge cleaning, and provides a strong guarantee for the reservoir scheduling work of the hydropower station.
