Abstract
Description
Technical Field
[0001] This utility model relates to a leak detection device for power plants. Background Technology
[0002] In modern power plants, the layout of equipment within the machine room is extremely complex, with pipes, cables, valves, and various machines intertwined and densely packed. This complex environment presents numerous challenges to leak detection. Firstly, many potential leak points are located in concealed locations such as narrow gaps, the bottom of equipment, and corners, making them difficult to observe directly. For example, leaks at pipe connections, cable penetrations through walls, and in the nooks and crannies of equipment are often difficult to detect promptly, even after they have occurred. Secondly, traditional manual inspection methods are inefficient and pose significant safety hazards. During inspections, workers often need to climb to high places or crouch on the ground, which is not only physically demanding but also limits the detection range, easily overlooking small leaks. More seriously, climbing and crouching pose significant risks of head injuries, falls, or even fatal falls from heights. Furthermore, with the increasing demand for intelligent and efficient power plants, traditional detection methods are no longer sufficient to meet the requirements for rapid and accurate leak location, necessitating a new type of detection device to address these issues. Utility Model Content
[0003] The purpose of this invention is to provide a leak detection device for power plants, which solves the problem that leaks in power plants are often well-hidden and difficult to detect.
[0004] To solve the above problems, the technical solution of this utility model is as follows:
[0005] A leak detection device for power plants includes a detection tube with a steering mechanism installed at the front end. A humidity sensor, a gas sensor, and a camera are installed on the moving end of the steering mechanism. A detection box is fixedly connected to the rear end of the detection tube. A controller is installed inside the detection box. A speaker, a display screen, and multiple control buttons are installed on the detection box. The display screen and speaker are connected to the output of the controller, and the humidity sensor, gas sensor, camera, and control buttons are connected to the input of the controller.
[0006] Furthermore, the steering mechanism includes a geared motor with one end installed inside the detection tube, a support connected to the output shaft of the geared motor, a servo motor mounted on the support, a gas sensor and a camera mounted on the servo motor's slewing arm, and the geared motor and servo motor connected to the controller output.
[0007] Furthermore, grooves are provided on the outer walls of both sides of the detection tube, and sliders are mounted on the grooves. Wheels are installed on both sides of the sliders.
[0008] Furthermore, a locking screw is installed on the slider.
[0009] Furthermore, a handle is connected to the end of the detection tube.
[0010] Furthermore, a wireless communication module is installed inside the detection box, through which the controller communicates with the terminal.
[0011] Furthermore, the camera is equipped with a fill light.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. Comprehensive and Precise Detection: By integrating humidity sensors, gas sensors, and high-resolution cameras into the moving end of the steering mechanism, comprehensive detection can be performed in various hidden corners within the power plant's generator room. The humidity sensor accurately detects humidity changes, promptly identifying leaks in water pipes; the gas sensor has high sensitivity for different types of leaked gases, quickly detecting excessive levels of carbon dioxide, oil, and other substances; and the camera provides clear images of hard-to-observe locations, facilitating the discovery of even the smallest leaks, significantly improving the accuracy and comprehensiveness of the detection.
[0014] 2. Safe and convenient operation: The device is equipped with a handle and a slider structure with wheels. During inspections, staff can use it as a trolley to reduce labor intensity. When encountering narrow holes or other special situations, the position of the wheels can be adjusted to avoid obstructing the camera's deep detection. Furthermore, it eliminates the need for staff to climb to high places or bend over, effectively reducing safety risks and ensuring the personal safety of staff.
[0015] 3. Highly Efficient Data Transmission and Management: The wireless communication module within the detection box enables the device to transmit data remotely. Upon detecting a leak, it can quickly send captured photos or short videos to a terminal computer for archiving. This allows technicians to promptly analyze and assess the leak, develop appropriate solutions, and improve the efficiency and scientific rigor of leak management.
[0016] 4. Strong adaptability to complex environments: The camera has a built-in supplementary light, enabling it to operate normally in dimly lit environments and ensuring clear images in various complex computer room environments. The geared motor and servo motor in the steering mechanism work together to flexibly adjust the camera's shooting angle, further enhancing the device's detection capabilities in complex environments.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 7 As shown, a leak detection device for power plants includes a detection tube 2 made of aluminum alloy. A steering mechanism is installed at the front end of the detection tube 2. A humidity sensor 11, a gas sensor 13, and a camera 12 are installed on the moving end of the steering mechanism. A detection box 4 is fixedly connected to the rear end of the detection tube 2. A controller and a power supply are housed inside the detection box 4. A speaker 15, a display screen 6, and multiple control buttons 7 are installed on the detection box 4. The display screen 6 and speaker 15 are connected to the controller output, while the humidity sensor 11, gas sensor 13, camera 12, and control buttons 7 are connected to the controller input. The control buttons 7 include a power switch, a shutter button, and four directional buttons. The four directional buttons are used to control the following geared motor 14 and servo motor 10.
[0028] The following components are included: Humidity sensor 11: HIH-4000. The HIH-4000 offers high accuracy and stability, but is relatively expensive, making it suitable for leak detection in power plants where high humidity accuracy is required. It can accurately determine if water pipes are leaking. Gas sensor 13: MG811, MQ-4, or MQ-5 are selected. The MG811 has high sensitivity to carbon dioxide, quickly detecting excessive levels; the MQ-4 has high sensitivity to combustible gases such as methane; and the MQ-5 is effective for detecting natural gas, liquefied petroleum gas, and other oil and gas. The choice depends on the type of gas that may be leaking from the power plant. Camera 12: IMX219. The IMX219 offers high resolution and low noise, providing clearer images and facilitating the detection of minute leaks. Controller: STM32F103. Power supply: 18650 lithium battery. Display screen 6: TFT LCD screen. The TFT LCD screen can display color images and rich information. Gear motor 14: DC gear motor 1437GB520-120. Servo 10: SG90 is selected.
[0029] During use, the operator holds the detection tube 2 and inserts the humidity sensor 11, gas sensor 13, and camera 12 into the nooks and crannies of the factory to be inspected, such as the gap between the reducer and the wall, the gap between pipes, inside the oil tank, the inspection hole, and behind the cable. During the inspection, the camera 12 is inserted into a location that cannot be seen by the naked eye, such as the gap at the bottom of the cabinet, the pipe flange, the valve, or the machine oil pan. The operator observes the display screen 6 to see if there are any leaks. At the same time, the odor sensor checks for gases, such as carbon dioxide or oil vapor. If the detected level exceeds the standard, the speaker 15 immediately activates the alarm. Simultaneously, the humidity sensor 11 detects the humidity and displays the humidity value on the display screen 6 to determine if the water pipe is leaking.
[0030] The steering mechanism includes a geared motor 14 with one end installed in the detection tube 2, a support connected to the output shaft of the geared motor 14, a servo motor 10 mounted on the support, a gas sensor 13 and a camera 12 mounted on the servo motor 10's rotating arm, and the geared motor 14 and the servo motor 10 connected to the controller output.
[0031] When using, such as Figure 6 As shown, the camera 12 is controlled by the geared motor 14 to rotate around the axis of the detection tube 2, and the camera 12 is controlled by the servo motor 10 to flip up and down. This allows the position of the camera 12, which is deep inside the machine, to be adjusted so that its shooting range can be increased and more fields of view can be obtained, enabling the inspection of leaks in more difficult corners.
[0032] Slide grooves 3 are formed on the outer walls of both sides of the detection tube 2. Semi-circular sliders 8 are mounted on the slide grooves 3, with locking blocks at both ends of the sliders inserted into the slide grooves 3. Wheels 1 are installed on both sides of the sliders 8. Figure 1 As shown, when staff are conducting inspections, for example, if only the bottom of the machine and the ground need to be checked, the detection device can be used as a small cart to push and inspect, which can greatly reduce the labor intensity of the workers. If some corners are knocked over and the traveling wheel 1 obstructs the camera 12 from entering the hole, the traveling wheel 1 can be moved along the slide 3 towards the rear end of the detection tube 2, which can avoid obstructing the camera 12 from entering the hole.
[0033] A locking screw 9 is installed on the slider 8. The locking screw is used to fix the traveling wheel 1 and prevent the traveling wheel 1 from sliding on its own.
[0034] A handle 5 is connected to the tail end of the detection tube 2, and the axis of the handle 5 intersects the axis of the detection tube 2. This makes it convenient for staff to push the detection device by hand.
[0035] The detection box 4 is equipped with a 4G wireless communication module, through which the controller communicates with the terminal. After a leak is detected, pressing the photo button will send the captured photo or short video to the terminal computer via the wireless communication module. The terminal computer will then archive the leak location, and technicians will determine whether the leak needs to be addressed and the extent of the leak.
[0036] The camera 12 is equipped with a fill light. When the camera 12 is shooting, the fill light is used to illuminate dark areas.
[0037] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
