Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a power plant fire monitoring device. Background Technology

[0002] Power plants, as crucial sites for electricity production, contain a large amount of electrical equipment, flammable cables, and various oil products, posing a high risk of fire. A fire would not only severely damage power plant equipment and disrupt power supply, affecting normal social production and daily life, but could also endanger the lives of workers. Therefore, real-time monitoring through fire monitoring equipment is essential. Traditional monitoring equipment in hydropower plant workshops is mostly fixed in a specific location within the workshop. The monitoring range of a single device is limited, easily leading to blind spots. Installing a large number of monitoring devices increases the cost of setup, hindering comprehensive safety inspections of the hydropower plant's production workshop. Furthermore, traditional monitoring equipment in hydropower plant workshops has limited functionality and practicality.

[0003] Existing technology CN221103423U discloses a hydropower plant inspection and monitoring device, including a fixed rail and a mobile frame. The fixed rail has symmetrically arranged guide grooves on both side walls, and guide sliders are symmetrically fixedly installed on the inner side wall of the mobile frame, with the guide sliders embedded in the guide grooves. This utility model enables mobile inspection and monitoring of the hydropower plant area using a single monitoring device, minimizing blind spots and offering flexible operation. Simultaneously, while the main monitoring camera is conducting inspections, fire detectors and hazardous gas detectors mounted on the bottom of a perforated mounting plate can monitor and alarm for sudden fires or leaks of toxic or hazardous gases in the hydropower plant area, promptly relaying the detected information to back-end monitoring personnel for rapid response and mitigation of potential disaster losses. This achieves a multifunctional and highly practical hydropower plant inspection and monitoring device.

[0004] While the aforementioned hydropower plant inspection and monitoring devices can monitor fires in real time, the complex environment of power plants and the long-term exposure of monitoring equipment to the elements make them prone to accumulating large amounts of dust, thus affecting the monitoring effectiveness. Utility Model Content

[0005] The purpose of this utility model is to provide a power plant fire monitoring device that solves the problem that although the existing technology can monitor the fire situation in real time, the environment of the power plant is complex and the monitoring equipment is exposed to the outside for a long time, which makes it easy to accumulate a lot of dust, thus affecting the monitoring effect.

[0006] To achieve the above objectives, this utility model provides a power plant fire monitoring device, including a mounting base, a camera, a fire detector, a hazardous gas detector, and a cleaning assembly. The camera, the fire detector, and the hazardous gas detector are all mounted on the mounting base. The cleaning assembly includes a connecting base, a shaft, an arc-shaped frame, a nozzle, a connecting component, and a driving component. The connecting base is fixedly connected to the mounting base and located on the side of the mounting base closer to the camera. The shaft is rotatably mounted on the connecting base. The arc-shaped frame is sleeved on the outside of the shaft and fixedly connected to the shaft. The nozzle is fixedly mounted on the arc-shaped frame and located on the side of the arc-shaped frame closer to the camera. The connecting component is mounted on the arc-shaped frame. The driving component drives the arc-shaped frame to rotate.

[0007] The connecting component includes a gas distributor, a main pipe, and a branch pipe. The gas distributor is fixedly connected to the arc-shaped frame and is located on the side of the arc-shaped frame away from the nozzle. The main pipe is connected to the distributor. The two ends of the branch pipe are respectively connected to the gas distributor and the nozzle.

[0008] The driving component includes a worm gear, a worm, and a drive motor. The worm gear is fixedly connected to the shaft and located at one end of the shaft. The worm is rotatably mounted on the mounting base and meshes with the worm gear. The drive motor is mounted on the mounting base, and the output shaft of the drive motor is fixedly connected to the worm.

[0009] The drive component further includes a protective cover, which is detachably connected to the mounting base and located on the side of the mounting base near the worm gear.

[0010] The cleaning component includes a cleaning brush, which is fixedly connected to the arc-shaped frame and located on the side of the cleaning brush near the blow nozzle.

[0011] This utility model discloses a power plant fire monitoring device, comprising a mounting base, a camera, a fire detector, a hazardous gas detector, and a cleaning component. The camera, fire detector, and hazardous gas detector are all mounted on the mounting base. The cleaning component includes a connecting base, a shaft, an arc-shaped frame, a nozzle, a connecting member, and a driving member.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the power plant fire monitoring equipment of this utility model. Figure 2 This is a structural schematic diagram of the driving component of this utility model. Figure 3 This is a structural schematic diagram of the cleaning brush 116 of this utility model.

[0020] This utility model discloses a power plant fire monitoring device, comprising a mounting base 101, a camera 102, a fire detector 103, a hazardous gas detector 104, a connecting base 105, a shaft 106, an arc-shaped frame 107, a nozzle 108, a gas distributor 109, a main pipe 110, a branch pipe 111, a worm gear 112, a worm 113, a drive motor 114, a protective cover 115, and a cleaning brush 116. It solves the problem that while existing technologies can monitor fires in real time, the complex environment of power plants and the long-term exposure of monitoring equipment to dust accumulation can negatively impact monitoring effectiveness. It is understood that the aforementioned solution can also be used to improve monitoring performance.

[0021] In this embodiment, the mounting base 101 has mounting holes to facilitate the installation of the device on the ceiling or wall. The camera 102, the fire detector 103, and the hazardous gas detector 104 are all existing technologies. The specific structure refers to the existing technology CN221103423U, a hydropower plant inspection and monitoring device. The cleaning component is installed on the mounting base 101, thereby solving the problem that although the existing technology can monitor the fire in real time, the environment of the power plant is complex, and the monitoring equipment is exposed to the outside for a long time, which easily accumulates a lot of dust, thus affecting the monitoring effect.

[0022] The connecting seat 105 is fixedly connected to the mounting seat 101 and located on the side of the mounting seat 101 near the camera 102. The shaft 106 is rotatably mounted on the connecting seat 105. The arc-shaped frame 107 is sleeved on the outside of the shaft 106 and fixedly connected to the shaft 106. The blow nozzle 108 is fixedly mounted on the arc-shaped frame 107 and located on the side of the arc-shaped frame 107 near the camera 102. The connecting member is mounted on the arc-shaped frame 107. The driving member drives the arc-shaped frame 107 to rotate. There are two connecting seats 105, located on the left and right sides of the mounting surface of the mounting seat 101. There are two shafts 106, which are connected to the two connecting seats 105 respectively through bearings. The arc-shaped frame 107 is arc-shaped, with both ends sleeved on the two shafts 106 respectively. Through the connecting seats 105 and the shafts 106, the arc-shaped frame 107 can rotate. The 7-axis frame is rotatable. There are four nozzles 108, all mounted on the inner arc surface of the arc frame 107. The two nozzles 108 on the left and right sides correspond to the fire detector 103 and the hazardous gas detector 104, respectively. The two nozzles 108 in the middle are set at a certain angle to blow air onto the camera 102. The connecting component is used to supply gas to the four nozzles 108. The driving component is used to drive the arc frame 107 to rotate, changing the blowing angle of the nozzles 108 and improving the cleaning effect. Through the blowing of the nozzles 108, the camera 102, the fire detector 103, and the hazardous gas detector 104 can be cleaned, preventing dust accumulation. This solves the problem that while existing technologies can monitor fires in real time, the complex environment of power plants and the long-term exposure of monitoring equipment to dust can easily lead to dust accumulation, thus affecting the monitoring effect.

[0023] Secondly, the gas distributor 109 is fixedly connected to the arc frame 107 and is located on the side of the arc frame 107 away from the nozzle 108; the main pipe 110 is connected to the distributor; the two ends of the branch pipe 111 are respectively connected to the gas distributor 109 and the nozzle 108. The gas distributor 109 is installed on the outer arc surface of the arc frame 107 and plays the role of connecting and distributing the gas pipe. One end of the main pipe 110 is connected to an external gas source, and the other end is connected to the gas distributor 109. There are four branch pipes 111, which are used to connect four nozzles 108. Through the connecting components, the gas is transported.

[0024] Meanwhile, the worm gear 112 is fixedly connected to the shaft 106 and located at one end of the shaft 106; the worm 113 is rotatably mounted on the mounting base 101 and meshes with the worm gear 112; the drive motor 114 is mounted on the mounting base 101, the output shaft of the drive motor 114 is fixedly connected to the worm 113, the worm gear 112 is sleeved on the end of one of the shafts 106, the worm 113 is mounted on the mounting base 101 through a bearing bracket, the drive motor 114 is used to drive the worm 113 to rotate, the drive motor 114 is equipped with a matching controller, which can make the drive motor 114 operate according to a set direction, speed, and time. Through the operation of the drive motor 114, under the transmission of the worm 113 and the worm gear 112, the shaft 106 drives the arc frame 107 to rotate.

[0025] In addition, the protective cover 115 is detachably connected to the mounting base 101 and is located on the side of the mounting base 101 near the worm 113. The protective cover 115 is installed on the mounting base 101 by screws, covering the worm wheel 112 and the worm 113. The protective cover 115 can thus protect the worm wheel 112 and the worm 113.

[0026] Finally, the cleaning brush 116 is fixedly connected to the arc frame 107 and is located on the side of the cleaning brush 116 near the blow nozzle 108. The cleaning brush 116 is installed in the middle of the inner arc surface of the arc frame 107. When the arc frame 107 rotates, the cleaning brush 116 can sweep the camera 102, thereby playing an auxiliary cleaning role.

[0027] In this embodiment, when not being cleaned, the side of the arc-shaped frame 107 is in close contact with the mounting base 101, without affecting the normal operation of the monitoring equipment. During cleaning, the camera 102 is first rotated so that its lens faces downwards. Then, an external source is activated, and gas is sprayed out through the four nozzles 108 to blow gas onto the fire detector 103, the hazardous gas detector 104, and the camera 102. Simultaneously, the controller controls the drive motor 114 to operate according to the set cleaning program, driving the arc-shaped frame 107 to rotate repeatedly, achieving multi-angle blowing. In addition, during the rotation of the arc-shaped frame 107, the cleaning brush 116 can sweep and clean the lens of the camera 102. This application, by setting the nozzles 108, can blow and clean the monitoring equipment, thereby solving the problem that although the prior art can monitor the fire situation in real time, the environment of the power plant is complex, and the monitoring equipment is exposed to the outside for a long time, which easily accumulates a lot of dust, thus affecting the monitoring effect.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
