Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet fan technology, and in particular relates to a power distribution cabinet fan with a monitoring device. Background Technology

[0002] During the operation of a power system, the distribution cabinet, as the core equipment for the installation of electrical components and circuit control, directly affects the safety and reliability of the power supply. During long-term operation, the internal electrical components of the distribution cabinet continuously generate heat. If this heat cannot be dissipated in time, the internal temperature will rise, potentially causing component performance degradation and shortened lifespan. In severe cases, it can even lead to safety accidents such as short circuits and burnouts. Therefore, ventilation equipment such as fans is required to dissipate heat within the cabinet. Furthermore, to monitor the status of the internal components in real time and promptly detect abnormalities (such as loose components, unusual noises, or early signs of fire), additional monitoring devices are typically required for the distribution cabinet.

[0003] However, in traditional solutions, the ventilation fans and monitoring equipment of the power distribution cabinet are often designed and installed independently. On the one hand, the independently installed monitoring equipment requires its own internal space in the power distribution cabinet, which can lead to a crowded internal layout for smaller cabinets, affecting the installation and maintenance of other components. On the other hand, the monitoring equipment itself generates heat during operation. The power distribution cabinet is already in a relatively enclosed high-temperature environment. If the monitoring equipment cannot dissipate heat in time, it is prone to crashes, screen freezes, and other malfunctions, affecting the stability of the monitoring function. Moreover, the fan will generate vibrations during operation. These vibrations are transmitted to the monitoring equipment through the power distribution cabinet, which can easily cause the camera lens to shift and the image to become blurry, reducing the clarity and accuracy of the monitoring image and making it difficult to effectively perform the monitoring function. Therefore, we propose a power distribution cabinet fan with a monitoring device. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a power distribution cabinet fan with a monitoring device, which achieves the effects of shock absorption and heat dissipation for the camera.

[0005] In view of this, the present invention provides a power distribution cabinet fan with a monitoring device, comprising a fan body for realizing ventilation function in the power distribution cabinet and a camera. The upper end of the fan body is equipped with a positioning and vibration damping component, which is used to position the monitoring camera and reduce the vibration of the camera. The front end of the fan body is also equipped with a heat dissipation component, which is used to dissipate heat from the camera. The positioning and vibration damping component and the heat dissipation component cooperate to form an airflow guiding channel. The airflow generated by the operation of the fan body is delivered to both sides of the camera through the airflow guiding channel, and the camera is cooled by the airflow.

[0006] Furthermore, the positioning and shock absorption component includes a hollow shell disposed on the main body of the fan. The hollow shell is fixedly connected to the main body of the fan by welding. A mounting bracket is welded to the upper end of the main body of the fan. The camera is disposed in the middle of the mounting bracket. A nut is fixedly installed in the middle of the hollow shell. A screw is disposed in the inner cavity of the nut. A rubber pressure plate is disposed on the side of the screw near the mounting bracket.

[0007] Furthermore, a rubber pad is bonded to the inner side of the mounting bracket, and the rubber pads are symmetrically arranged. The upper end of the rubber pad is flush with the upper edge of the mounting bracket, and a rubber support block is bonded to the middle of the lower end of the mounting bracket.

[0008] Furthermore, multiple heat-conducting strips are provided on both sides of the mounting bracket, and the heat-conducting strips are connected to the mounting bracket by welding. The side of the heat-conducting strip closest to the camera is flush with the side of the mounting bracket closest to the camera.

[0009] Furthermore, the size of the screw is adapted to the size of the nut, and the screw and nut are helically connected, while the rubber pressure plate and the screw are rotatably connected via bearings.

[0010] Furthermore, the heat dissipation component includes an arc-shaped guide channel disposed at the front end of the fan body, an air inlet is provided at the lower end of the arc-shaped guide channel, and the air inlet of the arc-shaped guide channel is inclinedly disposed at the front end of the fan body. An exhaust pipe is connected to the air outlet end of the arc-shaped guide channel, and the other end of the exhaust pipe is connected to the air inlet end of the shell.

[0011] Furthermore, multiple air vents are provided on both the left and right sides of the shell, and the air vents are equidistant from each other, with the air vents located on both sides of the camera.

[0012] Furthermore, the arc-shaped guide channel is located on the upper front side of the fan body, and the upper edge of the arc-shaped guide channel is lower than the upper edge of the rubber support block.

[0013] Furthermore, a protective shell is welded to the front end of the fan body, and a protective cover is provided on the rear side of the fan body.

[0014] The beneficial effects of this utility model are:

[0015] 1. Integrating a camera into the power distribution cabinet fan achieves the dual functions of ventilation and heat dissipation as well as real-time monitoring. This eliminates the need for separate monitoring equipment in the power distribution cabinet, reducing equipment investment costs and the space occupied inside the cabinet. The positioning and shock absorption components not only stably fix the camera, but their buffering and shock absorption performance also effectively reduces the vibration generated by the fan during operation, preventing camera lens displacement and image blurring caused by vibration, thus ensuring the stability and clarity of the monitoring image. At the same time, the heat dissipation components and the positioning and shock absorption components work together to form an airflow guiding channel, which can guide the airflow generated by the fan to both sides of the camera. The airflow quickly removes the heat generated by the camera during operation, preventing performance degradation and shortened lifespan of the camera due to long-term high-temperature operation, ensuring that both the camera and the fan can work stably for a long time.

[0027] Reference Figures 1 to 4 A power distribution cabinet fan with a monitoring device includes a fan body 1 for ventilation within the power distribution cabinet and a camera 13. The upper end of the fan body 1 is equipped with a positioning and vibration damping component, which is used to position the monitoring camera 13 and reduce its vibration. The front end of the fan body 1 is also equipped with a heat dissipation component, which is used to dissipate heat from the camera 13. The positioning and vibration damping component and the heat dissipation component work together to form an airflow guiding channel. The airflow generated by the operation of the fan body 1 is transported to both sides of the camera 13 through the airflow guiding channel, and the camera 13 is cooled by the airflow.

[0028] In this application, when the fan body 1 is powered on, its fan blades rotate to generate airflow. On the one hand, this directly ventilates the interior space of the distribution cabinet, reducing the overall temperature of the electrical components inside the cabinet and achieving basic ventilation and heat dissipation. On the other hand, the camera 13 is integrated into the fan body 1. The image acquisition module of the camera 13 captures real-time images of the interior and surrounding environment of the distribution cabinet, and then transmits the monitoring images to an external terminal via the data transmission module, achieving real-time monitoring. The positioning and vibration damping component is connected to the fan body 1 through its own structure, stably fixing the camera 13 in a preset position. At the same time, the buffer and vibration damping structure in the positioning and vibration damping component can absorb the vibration waves generated by the fan during operation, reducing the transmission of vibration to the camera 13. Furthermore, the heat dissipation component and the positioning and vibration damping component work together to form an airflow guiding channel. Some of the airflow generated by the fan operation will enter this channel and flow directionally to both sides of the camera 13 along the channel path. The airflow forms a flowing airflow layer on the surface of the camera 13, which carries away the heat generated by the camera 13 during operation through heat exchange, achieving heat dissipation protection for the camera 13.

[0029] In the example of this application, the positioning and shock absorption component includes a hollow shell 12 disposed on the fan body 1. The hollow shell 12 is fixedly connected to the fan body 1 by welding. A mounting bracket 2 is welded to the upper end of the fan body 1. A camera 13 is disposed in the middle of the mounting bracket 2. A nut 22 is fixedly installed in the middle of the hollow shell 12. A screw 21 is disposed in the inner cavity of the nut 22. A rubber pressure plate 23 is disposed on the side of the screw 21 near the mounting bracket 2.

[0030] As a preferred example of this utility model, the hollow shell 12 of the positioning and damping component is fixedly connected to the main body 1 of the fan by welding process to form the mounting base of the positioning and damping component, ensuring that the positioning and damping component as a whole remains relatively stable with the main body 1 of the fan. Mounting bracket 2 is welded to the upper end of the fan body 1. Its internal dimensions are adapted to the size of a common camera 13. The camera 13 is placed inside the mounting bracket 2. When it is necessary to clamp the camera 13, rotate the screw 21 clockwise. The screw 21 moves axially toward the camera 13 under the action of the internal thread of the nut 22. The rubber pressure plate 23 connected to the end of the screw 21 moves synchronously with the screw 21 until the rubber pressure plate 23 is in close contact with the surface of the mounting bracket 2. Continue to rotate the screw 21. The rubber pressure plate 23 generates a deformation force on the mounting bracket 2, so that the mounting bracket 2 forms a clamping force on the camera 13, thereby fixing the camera 13 in the mounting bracket 2. If it is necessary to disassemble or adjust the camera 13, rotate the screw 21 counterclockwise. The screw 21 drives the rubber pressure plate 23 away from the camera 13, and the clamping force disappears, so the camera 13 can be operated.

[0031] It is worth noting that mounting bracket 2 is made of flexible stainless steel.

[0032] In the example of this application, a rubber pad 24 is bonded to the inner side of the mounting bracket 2, and the rubber pads 24 are symmetrically arranged. The upper end of the rubber pad 24 is flush with the upper port edge of the mounting bracket 2, and a rubber support block 25 is bonded to the middle of the lower end of the mounting bracket 2.

[0033] As a preferred example of this utility model, the rubber pads 24 symmetrically bonded to the inner side of the mounting bracket 2 ensure close contact between the rubber pads 24 and the sides of the camera 13's housing after the camera 13 is placed in the mounting bracket 2. Due to the elasticity of the rubber pads 24, when the camera 13 is subjected to external forces in the left-right direction (such as vibrations transmitted by a fan), the rubber pads 24 absorb the energy of the external force, weakening the impact on the camera 13. Simultaneously, they fill the gap between the camera 13 and the inner side of the mounting bracket 2, preventing the camera 13 from shifting left or right within the mounting bracket 2 and maintaining the stability of the camera 13's installation position. The rubber support block 25 at the lower center of the mounting bracket 2 has its upper surface in contact with the bottom of the camera 13, providing upward support for the camera 13. This, combined with the clamping forces on both sides of the mounting bracket 2, balances the weight distribution of the camera 13, preventing uneven force distribution caused by the camera 13 relying solely on the clamping forces on both sides and resulting in the bottom being suspended. Furthermore, the rubber material of the rubber support block 25 has shock-absorbing properties, absorbing vibrations transmitted from the bottom of the mounting bracket 2, further reducing the impact of vibrations on the camera 13.

[0034] In the example of this application, multiple heat-conducting strips 3 are provided on both sides of the mounting bracket 2, and the heat-conducting strips 3 are connected to the mounting bracket 2 by welding. The side of the heat-conducting strip 3 near the camera 13 is flush with the side of the mounting bracket 2 near the camera 13.

[0035] As a preferred example of this utility model, the camera 13 generates heat during operation, and some of this heat is transferred to the mounting bracket 2 in contact with it through thermal conduction. The heat-conducting strips 3 welded to both sides of the mounting bracket 2 are made of a material with high thermal conductivity (such as aluminum alloy or copper alloy), which can quickly receive the heat transferred from the mounting bracket 2 and conduct the heat to the entire surface of the heat-conducting strips 3. Since the heat-conducting strips 3 are long strip structures and numerous, their contact area with the air is much larger than that of the mounting bracket 2 itself. The cold air in the air exchanges heat with the surface of the heat-conducting strips 3, and the heat is dissipated into the air through convection, achieving rapid heat conduction and dissipation. At the same time, the arc-shaped guide channel 14 allows the airflow to flow over the surface of the heat-conducting strips 3 when passing through both sides of the camera 13, accelerating the airflow over the surface of the heat-conducting strips 3 and further improving the heat dissipation efficiency of the heat-conducting strips 3. This works in conjunction with the airflow heat dissipation to more efficiently reduce the temperature of the camera 13. In addition, the side of the heat-conducting strip 3 closest to the camera 13 is flush with the inner side of the mounting bracket 2. When the camera 13 is placed in or removed from the mounting bracket 2, the heat-conducting strip 3 will not obstruct the camera 13, ensuring a smooth installation and removal process for the camera 13.

[0036] In the example of this application, the size of the screw 21 is adapted to the size of the nut 22, and the screw 21 and the nut 22 are connected by a screw. The rubber pressure plate 23 is rotatably connected to the screw 21 through a bearing.

[0037] As a preferred example of this utility model, when the screw 21 is rotated, the screw 21 can move smoothly along the axial direction, thereby controlling the movement distance of the rubber pressure plate 23, ensuring that the rubber pressure plate 23 can accurately align with the camera 13 and apply a uniform clamping force, and preventing the camera 13 from loosening due to insufficient clamping force.

[0038] In the example of this application, the heat dissipation component includes an arc-shaped guide channel 14 disposed at the front end of the fan body 1. An air inlet is provided at the lower end of the arc-shaped guide channel 14, and the air inlet of the arc-shaped guide channel 14 is obliquely disposed at the front end of the fan body 1. An exhaust pipe 15 is connected to the air outlet end of the arc-shaped guide channel 14, and the other end of the exhaust pipe 15 is connected to the air inlet end of the shell 12.

[0039] As a preferred example of this utility model, when the fan body 1 is running, the airflow generated by the rotation of the fan blades flows towards the front end of the fan. The inclined air inlet increases the airflow entry area and reduces the airflow resistance when entering the channel (avoiding the vertical impact of airflow on the channel wall to generate vortices), allowing more airflow to smoothly enter the arc-shaped guide channel 14. The arc-shaped structure of the arc-shaped guide channel 14 guides the airflow to flow smoothly along the inner wall of the channel, reducing the energy loss of the airflow in the channel. The airflow flows through the arc-shaped guide channel 14 to the exhaust pipe 15, which is connected to the air inlet end of the hollow shell 12. The airflow enters the interior of the hollow shell 12 through the exhaust pipe 15. The interior of the hollow shell 12 is a hollow structure, which can temporarily store the airflow and make the airflow evenly distributed. Subsequently, the airflow flows out from the openings of the hollow shell 12 corresponding to the camera 13, acting on both sides of the camera 13, thereby achieving the heat dissipation effect on the camera 13.

[0040] In the example of this application, multiple air vents 16 are provided on both the left and right sides of the shell 12, and the air vents 16 are equidistant from each other, and the air vents 16 are located on both sides of the camera 13.

[0041] As a preferred example of this utility model, when airflow enters the interior of the shell 12 from the exhaust pipe 15, the airflow pressure inside the shell 12 gradually increases. The airflow flows towards the lower pressure vent 16. Since the vent 16 are equidistantly distributed, the airflow resistance of each vent 16 is similar, resulting in a basically consistent airflow rate from each vent 16. After the airflow exits from the vent 16, it directly blows onto the surfaces on both sides of the camera 13, forming a uniform airflow coverage layer. This avoids uneven heat dissipation caused by concentrated airflow in some areas and no airflow in others, ensuring that the overall temperature of the camera 13 remains balanced. At the same time, the equidistantly distributed vent 16 makes the airflow force relatively stable, preventing excessive impact on the camera 13 due to excessively strong local airflow, thus preventing slight shaking of the camera 13 under the action of airflow and maintaining stable operation of the camera 13.

[0042] In the example of this application, the arc-shaped guide channel 14 is disposed on the upper front side of the fan body 1, and the upper edge of the arc-shaped guide channel 14 is lower than the upper edge of the rubber support block 25.

[0043] As a preferred example of this utility model, when installing the camera 13, the camera 13 is placed from above the mounting bracket 2. Since the arc-shaped guide channel 14 does not protrude from the rubber support block 25, it will not obstruct the downward path of the camera 13, ensuring that the camera 13 can fall smoothly into the mounting bracket 2 and contact the rubber support block 25. When removing the camera 13, the camera 13 is lifted upwards, and it will not be obstructed by the arc-shaped guide channel 14, ensuring the convenience of installation and removal operations.

[0044] In the example of this application, a protective shell 11 is welded to the front end of the fan body 1, and a protective cover is provided on the rear side of the fan body 1.

[0045] As a preferred example of this utility model, the protective shell 11 forms a physical barrier to prevent personnel from accidentally touching the high-speed rotating fan blades when approaching the fan, thus avoiding safety accidents. The protective cover on the rear side of the fan body 1 also adopts a hollow design, thereby protecting the internal structure of the fan and extending its service life.

[0046] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
