Description

Technical Field

[0001] The utility model relates to the field of cleaning of filter screens in circulating pump rooms, and more specifically, to an automatic detection and cleaning device for jellyfish in filter screens in circulating pump rooms of power plants. Background Art

[0002] In coastal power plant operations, the circulating pump room, a core component of the cooling system, is crucial for overall plant efficiency and safety. The filter screens in the circulating pump room are tasked with intercepting impurities in the seawater and protecting subsequent equipment from damage. However, the complex marine ecosystem, particularly the frequent presence of aquatic organisms such as jellyfish, poses a serious risk of filter blockage.

[0003] Prior art relied primarily on manual cleaning of the pump room's filters. Maintenance personnel regularly entered the pump room to inspect and manually clean the filters of jellyfish and other impurities. This method was not only time-consuming and labor-intensive, but also posed significant safety risks. This was particularly true in inclement weather or sea conditions, where the operating environment was even harsher and cleaning efficiency was significantly reduced.

[0004] Furthermore, manual cleaning can be incomplete. Due to the large area and complex structure of the filter, manual cleaning often fails to cover all areas, leaving some impurities such as jellyfish behind, which in turn affects the filtration effect and the performance of the cooling system. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an automatic detection and cleaning device for jellyfish in a filter screen of a circulating pump room of a power plant, comprising: a control platform, a mechanical claw and a mechanical arm;

[0006] Among them, the control platform is connected to the mechanical claw through the mechanical arm; a camera is provided on the mechanical arm near the end of the mechanical claw; the control platform includes a shell, a mobile system, and a monitoring and operation module; the mobile system is provided at the bottom of the shell, and the monitoring and operation module is provided above the shell.

[0007] Preferably, the camera is connected to a bracket via a rotating joint, and the bracket is arranged on one end of the robotic arm close to the robotic claw.

[0008] Preferably, the moving system includes wheels and tracks, which cooperate with each other and are installed on both sides of the bottom of the shell to drive the shell to move.

[0009] Preferably, the monitoring and operation module includes a screen, an operation lever and operation buttons.

[0010] Preferably, the housing is also provided with an alarm indicator light, an emergency stop button, a main switch and a loudspeaker.

[0011] Preferably, the robotic arm consists of multiple joints.

[0012] Preferably, the mechanical claw is connected to the mechanical arm via a retractable component.

[0013] The beneficial effects of the utility model are:

[0014] 1. This utility model integrates a control platform, a robotic arm, and a mechanical claw to automatically detect and clean jellyfish from the filter screens in power plant circulating pump rooms. A camera on the robotic arm captures images of the filter area. The monitoring and operation module then accurately identifies the location and size of the jellyfish. The robotic arm then moves the mechanical claw to the target location for efficient cleaning. This device not only significantly improves cleaning efficiency but also ensures accuracy, reducing errors and omissions that can occur with manual operation.

[0015] 2. The mobile system of the present invention adopts a mobile method that combines wheels and tracks, which enables the entire device to move flexibly in the complex environment of the power plant's circulation pump room and adapt to different terrains and operational requirements. At the same time, the robotic arm is composed of multiple joints, and the mechanical claws are connected by retractable components, which further enhances the flexibility and operating range of the device. In addition, safety facilities such as the alarm indicator light, emergency stop button, main switch and loudspeaker installed on the shell can respond quickly in emergency situations to ensure the safety of operators. These designs together improve the safety and flexibility of operations and reduce operational risks and difficulty.

[0016] 3. This utility model uses the screen, operating lever, and operating buttons in the monitoring and operation module to allow operators to intuitively monitor the operating status of the device, facilitating management and maintenance work. Furthermore, the device is equipped with an alarm indicator and loudspeaker to alert operators to take timely action when abnormal conditions occur. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, Example 1 of the present application provides an automatic detection and cleaning device for jellyfish in a filter screen of a circulating pump room of a power plant, comprising: a control platform, a mechanical claw 1 and a mechanical arm 2;

[0026] Among them, the control platform is connected to the mechanical claw 1 through the mechanical arm 2; a camera 4 is provided on the mechanical arm 2 near the end of the mechanical claw 1; the control platform includes a shell 3, a mobile system 5, and a monitoring and operation module 6; the mobile system 5 is arranged at the bottom of the shell 3, and the monitoring and operation module 6 is arranged above the shell 3.

[0027] Specifically, the camera 4 is connected to a bracket 8 via a rotating joint 7. The bracket 8 is located on the end of the robotic arm 2 near the mechanical claw 1. The camera 4 is used to capture real-time images of the filter screen. A control module is located within the housing 3 and is connected to the camera 4 via a data cable. This module can process and analyze image data and identify target impurities such as jellyfish. The device also includes a drive and control system, which includes a motor, a transmission device, and a controller. These components are used to drive the movement of the robotic arm 2 and the mechanical claw 1 under the control of the control module.

[0028] The moving system 5 includes wheels 501 and tracks 502 . The wheels 501 and tracks 502 cooperate with each other and are installed on both sides of the bottom of the housing 3 to drive the housing 3 to move.

[0029] The monitoring and operation module 6 includes a screen 601, an operating lever 602, and operating buttons 603, which are used to monitor the working status of the device, receive alarm signals, and operate the device for cleaning. At the same time, the image can be transmitted to the remote PTZ and allowed remote control by maintenance personnel on the computer.

[0030] The housing 3 is also provided with an alarm indicator light 301 , an emergency stop button 302 , a main switch 303 and a loudspeaker 304 .

[0031] The mechanical arm 2 is composed of multiple joints and can be flexibly moved to various positions of the filter screen. The mechanical claw 1 is connected to the mechanical arm 2 through a retractable component 9 and is used to contact and remove impurities such as jellyfish.

[0032] Example 2:

[0033] Based on Example 1, Example 2 of the present application provides a working method of an automatic detection and cleaning device for jellyfish in a filter screen of a power plant circulating pump room, comprising:

[0034] Step 1: Startup and initialization: After the device is started, the initialization operation is first performed, including camera calibration, image recognition loading algorithm model and other steps.

[0035] Step 2, Detection Phase: Camera 4 continuously captures images of the filter and transmits them to the image recognition algorithm for processing. The image recognition algorithm uses a model to identify the location and size of target impurities such as jellyfish.

[0036] Among them, the image recognition algorithm can also be replaced by an algorithm based on machine vision and deep learning to process and analyze image data from high-definition cameras, identify impurities such as jellyfish, and control the robotic arm for cleaning.

[0037] Step 3, Cleaning Phase: When a jellyfish is detected, the control module sends a command to the drive and control system, driving the robotic arm 2 and the robotic claw 1 to move to the jellyfish location. The robotic claw 1 contacts the jellyfish and removes it from the filter through physical means.

[0038] Step 4: Recording and Alarming: During the cleaning process, the device records the cleaning data and stores it in internal memory. If a large number of jellyfish are detected or the cleaning effect is poor, the device will issue an alarm signal and prompt the operation and maintenance personnel to take action.

[0039] When the algorithm's automatic cleaning mode is not effective, you can also perform manual cleaning operations.

[0040] It should be noted that the above-mentioned algorithms are all existing technologies and will not be described in detail in this application.
