Description

Technical Field

[0001] The present invention relates to the technical field of remote monitoring camera devices, and in particular to an autonomous protective type remote monitoring device for operation and maintenance of electric power equipment. Background Art

[0002] With the popularization of monitoring systems, remote monitoring can be used to reduce operation and maintenance costs and workload during power equipment maintenance. However, the existing remote monitoring systems have poor coordination capabilities in various usage scenarios, and their functions of protecting equipment and data in emergencies are poor. At the same time, the types of information in remote monitoring are few and not intuitive enough, and the monitoring field of view is insufficient.

[0003] Chinese patent announcement No. CN221727795U discloses a remote monitoring device for operation and maintenance of electric power equipment, including an operating table, an operating panel is arranged on the front side of the operating table, an information panel is arranged inside the operating panel, a distribution box is arranged on one side of the operating table, a distribution box cover is arranged on the front side of the distribution box, a processor box is arranged on the top, an emergency light source is arranged on the front side of the processor box, a dust baffle is arranged on the top of the emergency light source, a smoke sensor is arranged on one side of the processor box, a moving horizontal axis is arranged on the other side of the processor box, a traction motor is arranged on the moving horizontal axis, a remote monitor is arranged below the traction motor, a rotating module is arranged on the remote monitor, a high-definition camera is arranged on the rotating module, and a thermal imager is arranged above the high-definition camera.

[0004] The above scheme improves the ability of the equipment to be adjusted and used on-site in the monitoring environment or as a remote external device to enhance the coordination of multi-scene use. However, the camera still uses traditional cameras that do not have autonomous protection capabilities. During the remote operation and maintenance monitoring process, some cameras will be damaged by humans, and the existing cameras do not have autonomous protection functions. The photographic part of the camera is extremely susceptible to damage when it is damaged, and the subsequent maintenance cost is high. In addition, ordinary cameras will lose their monitoring capabilities after being damaged and cannot provide effective information for subsequent investigations. Summary of the invention

[0005] To solve the above problems, a remote monitoring device for the operation and maintenance of autonomous protection type power equipment is provided. By sliding the first camera in the housing, it is ensured that the first camera can slide into the housing when subjected to an external force, reducing the degree of damage to the first camera when it is damaged by the outside world. At the same time, a lifting frame that moves vertically is provided at the bottom of the housing, and a second camera is provided on the lifting frame. The second camera is a panoramic camera. When the first camera is hit and retracts into the housing, the lifting frame drives the second camera to descend, and the second camera monitors the surrounding environment. In order to prevent the second camera from becoming a new target of damage after descending, a reset unit is provided on the upper part of the lifting frame. When the second camera completely descends below the housing, the reset unit drives the second camera to rise and reset, which not only ensures that the second camera can pop out in time to shoot the surrounding environment when the first camera is attacked by the outside world, and immediately retracts into the housing after shooting to avoid damage to the second camera, reducing the cost of later maintenance, but also can provide sufficient image data for later investigation.

[0006] To solve the problems of the prior art, the present invention provides a remote monitoring device for the operation and maintenance of autonomous protection type power equipment, including a housing with an opening on one side and a first camera arranged in the housing; the first camera is slidably arranged in the housing along the extending direction of the opening on the housing, a lifting frame is slidably arranged vertically through the bottom of the housing, a second camera is arranged on the lifting frame. During normal monitoring, the imaging end of the first camera is located at the opening of the housing, the bottom end face of the lifting frame is coplanar with the bottom end face of the housing, and the second camera is located inside the housing. When the first camera is subjected to an external force, the first camera slides into the housing, the lifting frame descends, and the second camera descends below the housing to photograph the surrounding environment. A reset unit is arranged on the lifting frame to drive the lifting frame to rise and reset after the lifting frame descends.

[0007] Preferably, the reset unit includes a heavy object that moves vertically inside the housing, a traction rope that fixedly connects the heavy object and the lifting frame is arranged between the heavy object and the lifting frame, a rotating wheel is rotatably arranged below the traction rope, and the traction rope is wound around the rotating wheel.

[0008] Preferably, there is an included angle between the moving direction of the first camera in the housing and the horizontal plane, and the included angle is an acute angle. The imaging end of the first camera is inclined downward and faces the opening of the housing.

[0009] Preferably, a first rack that moves synchronously with the first camera is fixedly arranged on the side wall of the first camera, a second rack that moves synchronously with the lifting frame is vertically fixedly arranged on the lifting frame, a gear set is arranged between the first rack and the second rack, and the first rack drives the second rack to lift through the gear set.

[0010] Preferably, the gear set includes a first gear disposed below the first rack and meshing with the first rack. A second gear meshing with the second rack is fixedly disposed at the end of the first gear. When the imaging end of the first camera is located at the opening of the housing, the first rack and the first gear mesh with each other. When the first camera is fully retracted into the housing, the first rack and the first gear are disengaged from meshing.

[0011] Preferably, the second camera is preferably a panoramic camera.

[0012] Preferably, an electromagnet for magnetically attracting the first camera that slides into the housing is disposed inside the housing, and the electromagnet is energized after the first camera slides into the housing.

[0013] Preferably, a rotation angle sensor is fixedly disposed at the end of the first gear, and a rated rotation angle is preset. When the first gear rotates to the rated rotation angle, the electromagnet is energized.

[0014] Preferably, a spring is disposed on one side of the electromagnet along the moving direction of the first camera, and both ends of the spring are fixedly connected to the end of the first camera and the inner wall of the housing respectively.

[0015] Preferably, a protection unit for shielding the opening on the housing after the first camera slides into the housing is disposed on the housing. The protection unit includes a receiving groove opened on the upper part of the housing. The receiving groove is an arc-shaped structure. An arc-shaped protection cover is slidably disposed in the receiving groove. A third gear is meshed above the first rack. A rotating arm fixedly connected to one side of the protection cover is fixedly disposed at the end of the third gear. The arc length of the receiving groove is greater than the arc length of the protection cover.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. By sliding the first camera in the housing, the present invention ensures that the first camera can slide into the housing when subjected to an external force, reducing the damage degree of the first camera when damaged by the outside world. At the same time, a lifting frame moving in the vertical direction is disposed at the bottom of the housing, and a second camera is disposed on the lifting frame. The second camera is a panoramic camera. When the first camera is impacted and retracted into the housing, the lifting frame drives the second camera to descend, and the second camera monitors the surrounding environment. In order to prevent the second camera from becoming a new target of damage after descending, a reset unit is disposed on the upper part of the lifting frame. When the second camera completely descends below the housing, the reset unit drives the second camera to rise and reset, which not only ensures that the second camera can pop up in time to shoot the surrounding environment when the first camera is attacked by the outside world, and immediately retracts into the housing after shooting to avoid damage to the second camera, reducing the later maintenance cost, but also can provide sufficient image data for later investigation.

[0017] 2. By setting the first rack, the second rack, the first gear and the second gear, when the first camera slides into the housing, the first rack moves synchronously with the first camera. Since the first rack and the first gear are in meshing state when the imaging end of the first camera is at the opening of the housing, when the first camera slides inward into the housing, the first rack can drive the first gear, and the first gear drives the second rack through the second gear, so that the second rack drives the lifting frame to descend vertically. Even after the external force is removed after the first camera slides into the housing, the first camera still continues to slide inward into the housing until it completely slides into the housing and then stops. The process of the first camera actively sliding into the housing after being impacted will be described later. When the first camera completely slides into the housing, the first rack fixedly arranged on the side of the first camera disengages from the first gear. At this time, the heavy object pulls the lifting frame through the traction rope, and the lifting frame drives the second gear through the second rack and makes the first gear rotate in the reverse direction, so that the lifting frame can drive the second camera to descend first and then ascend.

[0029] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] Refer to Figures 1 - 4 : A self-protective remote monitoring device for power equipment operation and maintenance, including a housing 2 with an opening 3 provided on one side and a first camera 1 provided in the housing 2; the first camera 1 is slidably arranged in the housing 2 along the extending direction of the opening 3 on the housing 2, a lifting frame 22 is slidably arranged vertically through the bottom of the housing 2, a second camera 21 is provided on the lifting frame 22, during normal monitoring, the imaging end of the first camera 1 is located at the opening 3 of the housing 2, the bottom end face of the lifting frame 22 is coplanar with the bottom end face of the housing 2, the second camera 21 is located inside the housing 2, when the first camera 1 is subjected to an external force, the first camera 1 slides into the housing 2, the lifting frame 22 descends, and the second camera 21 descends below the housing 2 to photograph the surrounding environment, and a reset unit 23 for driving the lifting frame 22 to rise and reset after the lifting frame 22 descends is provided on the lifting frame 22.

[0031] The core of the remote operation and maintenance device for power equipment is the camera component. During the maintenance of existing power equipment, in order to facilitate maintenance, multiple camera components are usually set up around the power equipment to monitor it, so as to achieve remote operation and maintenance monitoring of the power equipment. Around some important power equipment, protective nets are also set up to prevent human damage. The installation of camera components can remotely monitor the process of human damage to power equipment. Exactly because of this, the camera components will also become the targets of damage. During the process of remote operation and maintenance, if the camera components are damaged in advance, then when the subsequent power equipment is damaged, timely monitoring cannot be carried out, and at the same time, the faces of the damage personnel cannot be captured, making the subsequent investigation difficult. Most of the existing camera components do not have protection capabilities and have shooting blind spots. They are extremely easy to be damaged when being damaged, resulting in a large subsequent maintenance cost and being unable to timely capture the surrounding environment when being damaged. When the camera component with autonomous protection is damaged, the camera component usually retracts into the protective shell automatically. Although it can avoid the damage of the camera component, it also greatly reduces the field of view of the camera component during image acquisition, and even cannot collect the external environmental images. As a result, although the camera component is damaged, the faces of the personnel who carry out the damage cannot be accurately collected in time, and it cannot provide strong help for the subsequent investigation.

[0032] To avoid the above situation, the existing camera components are redesigned so that when the camera components are damaged by the outside world, they can not only ensure that the camera components are not damaged, but also enable the camera components to capture the faces of the personnel who carry out the damage in time when being damaged, providing strong evidence for the subsequent investigation. The specific structure and working process of the camera component in the remote monitoring device for operation and maintenance are as follows: During normal operation and maintenance monitoring, the camera end of the first camera 1 is located at the opening 3 of the outer shell 2. At this time, the camera end of the first camera 1 can monitor the most complete picture without being blocked by the outer shell 2, thus ensuring the monitoring range of the first camera 1 under normal operation and maintenance monitoring. At this time, the second camera 21 is located inside the outer shell 2, and the lower end face of the lifting frame 22 is coplanar with the bottom end face of the outer shell 2. When the first camera 1 is damaged by external impact, since the first camera 1 is slidably set in the outer shell 2 along the extension direction of the opening 3, the camera end of the first camera 1 slides into the outer shell 2 after being acted upon by external forces, thereby reducing the effect of external forces. If the first camera 1 is directly fixed on the outer shell 2, the first camera 1 can be slidably set in the outer shell 2 to further reduce the damage to the first camera 1. When the first camera 1 slides into the housing 2, the lifting frame 22 drives the second camera 21 to descend. The second camera 21 is preferably a panoramic camera. When the second camera 21 descends to the bottom of the housing 2 with the lifting frame 22, the second camera 21 can monitor the surrounding environment more comprehensively. At the same time, since the lifting frame 22 is provided with a reset unit 23, when the lifting frame 22 drives the second camera 21 to descend to the lowest position, the reset unit 23 drives the lifting frame 22 to rise and reset. When the second camera 21 descends to the bottom of the housing 2, it shoots the surrounding environment. Then the reset unit 23 drives the lifting frame 22 to rise again. The second camera 21 is retracted into the housing 2 driven by the lifting frame 2, which not only ensures that the second camera 21 can collect images of the external environment, so that the appearance of the person who carried out the destruction can be accurately collected, but also ensures that the second camera 21 will not be damaged, reducing the cost of later maintenance. It is worth noting that the first camera 1 will be completely retracted into the housing 2 after being hit by the outside world, avoiding secondary damage to the first camera 1.

[0033] By sliding the first camera 1 and arranging it inside the housing 2, it is ensured that when the first camera 1 is subjected to an external force, it can slide into the housing 2, reducing the degree of damage to the first camera 1 when it is externally damaged. At the same time, a lifting frame 22 that moves vertically is arranged at the bottom of the housing 2, and a second camera 21 is arranged on the lifting frame 22. The second camera 21 is a panoramic camera. When the first camera 1 is hit and retracts into the housing 2, the lifting frame 22 drives the second camera 21 to descend, and the second camera 21 monitors the surrounding environment. In order to prevent the second camera 21 from becoming a new target of damage after descending, a reset unit 23 is arranged on the upper part of the lifting frame 22. When the second camera 21 completely descends below the housing 2, the reset unit 23 drives the second camera 21 to rise and reset, which not only ensures that the second camera 21 can pop up in time to shoot the surrounding environment when the first camera 1 is externally attacked, and immediately retracts into the housing 2 after shooting to avoid damage to the second camera 21, reducing the cost of later maintenance, but also can provide sufficient image data for later investigation.

[0034] Refer to Figure 9 and Figure 10 : The reset unit 23 includes a heavy object 231 that is arranged to move vertically inside the housing 2. A traction rope 232 that fixedly connects the two is arranged between the heavy object 231 and the lifting frame 22. A rotating wheel 233 is rotatably arranged below the traction rope 232, and the traction rope 232 is wound around the rotating wheel 233.

[0035] There are various existing reset units 23, and the most commonly used one is an elastic element. When the lifting frame 22 descends, the elastic element stretches and provides an upward pulling force for the lifting frame 22. However, the weight of the lifting frame 22 needs to be supported by the elastic element for a long time. After being subjected to the gravity for a long time, the elastic element will show fatigue. When the first camera 1 is damaged, the first camera 1 slides into the housing 2, and the lifting frame 22 drives the second camera 21 to start descending. However, due to the reduced elastic ability of the elastic element, after the lifting frame 22 descends, it is easy for the elastic element to fail to drive the second camera 21 to reset smoothly, resulting in the second camera 21 being unable to retract into the housing 2 after shooting the surrounding environment, and finally the second camera 21 becomes a target of damage, and the later maintenance cost is relatively high. After the reset unit 23 is composed of the heavy object 231, the traction rope 232 and the rotating wheel 233, the heavy object 231 uses its own gravity to lift the lifting frame 22 through the traction rope 232. During long-term use, the mass of the heavy object 231 does not change, and its service life is longer than that of the elastic element, avoiding the situation where the lifting frame 22 fails to reset when the reset unit 23 is needed to reset the lifting frame 22, and ensuring that the second camera 21 can be stably reset after popping up and descending.

[0036] Refer toFigures 1 - 10 : There is an included angle between the moving direction of the first camera 1 inside the housing 2 and the horizontal plane, and the included angle is an acute angle. The imaging end of the first camera 1 is inclined downward and faces the opening 3 of the housing 2.

[0037] By setting the moving direction of the first camera 1 to be inclined, the first camera 1 can withstand external force impacts at more angles. If the moving direction of the first camera 1 is set to horizontal movement, when an external force only exerts a force in the vertical direction on the first camera 1, the first camera 1 will not move, which will cause the first camera 1 to be unable to release the force smoothly, and ultimately the first camera 1 needs to fully bear the impact of the external force, resulting in greater damage to the first camera 1. After setting the first camera 1 to move inclinedly, the adaptability of the first camera 1 to the force direction is improved.

[0038] Refer to Figure 5 and Figure 8 : A first rack 221 that moves synchronously with the first camera 1 is fixedly arranged on the side wall of the first camera 1. A second rack 222 that moves synchronously with the lifting frame 22 is vertically fixedly arranged on the lifting frame 22. A gear set 223 is arranged between the first rack 221 and the second rack 222. The first rack 221 drives the second rack 222 to lift through the gear set 223.

[0039] Refer to Figure 5 and Figure 8 : The gear set 223 includes a first gear 2231 arranged below the first rack 221 and meshing with the first rack 221. A second gear 2232 that meshes with the second rack 222 is fixedly arranged at the end of the first gear 2231. When the imaging end of the first camera 1 is located at the opening 3 of the housing 2, the first rack 221 meshes with the first gear 2231. When the first camera 1 is completely retracted into the housing 2, the first rack 221 and the first gear 2231 are disengaged.

[0040] By setting the first rack 221, the second rack 222, the first gear 2231 and the second gear 2232, when the first camera 1 slides into the housing 2, the first rack 221 moves synchronously with the first camera 1. Since the imaging end of the first camera 1 is at the opening 3 of the housing 2, the first rack 221 and the first gear 2231 are in a meshed state. So when the first camera 1 slides into the interior of the housing 2, the first rack 221 can drive the first gear 2231. The first gear 2231 drives the second rack 222 through the second gear 2232, causing the second rack 222 to drive the lifting frame 22 to descend vertically. Even after the external force is removed after the first camera 1 slides into the housing 2, the first camera 1 still continues to slide into the interior of the housing 2 until it completely slides into the housing 2 and then stops. The process of the first camera 1 actively sliding into the housing 2 after being impacted will be described later. When the first camera 1 completely slides into the housing 2, the first rack 221 fixedly arranged on the side of the first camera 1 disengages from the first gear 2231. At this time, the heavy object 231 pulls the lifting frame 22 through the traction rope 232. The lifting frame 22 drives the second gear 2232 through the second rack 222 and causes the first gear 2231 to rotate in the reverse direction, so that the lifting frame 22 can drive the second camera 21 to descend first and then ascend.

[0041] Refer to Figures 1 - 10 : The second camera 21 is preferably a panoramic camera.

[0042] Selecting the second camera 21 as a panoramic camera ensures that the second camera 21 can comprehensively photograph the surrounding environment after descending with the lifting frame 22.

[0043] Refer to Figure 6 : An electromagnet 24 for magnetically attracting the first camera 1 that slides into the housing 2 is provided inside the housing 2. The electromagnet 24 is energized after the first camera 1 slides into the housing 2.

[0044] When the first camera 1 is damaged by an external force, the first camera 1 slides into the interior of the housing 2 under the action of the external force, and the external force that damages the first camera 1 cannot act continuously. When the external force stops acting on the first camera 1, the energized electromagnet 24 can still magnetically attract the first camera 1. Since the first camera 1 is inclined and slidably arranged inside the housing 2, if the electromagnet 24 is not provided, the first camera 1 will slide out again after sliding into the housing 2. When the end of the first camera 1 contacts the electromagnet 24, the first camera 1 completely slides into the housing 2.

[0045] Refer to Figure 9:A rotation angle sensor 25 is fixedly arranged at the end of the first gear 2231, and a rated rotation angle is preset. When the first gear 2231 rotates to the rated rotation angle, the electromagnet 24 is energized.

[0046] The rotation angle of the first gear 2231 is monitored by the rotation angle sensor 25, and then the distance that the first camera 1 slides into the housing 2 is judged. In this way, it can be accurately judged whether the first camera 1 has encountered an external attack. This is because when the wind blows outside, the first camera 1 will also have a slight sliding fit with the housing 2. If the electromagnet 24 is activated only by the sliding of the first camera 1, it is easy to cause the electromagnet 24 to be accidentally energized and activated.

[0047] Refer to Figure 9 and Figure 10 :A spring 26 is arranged on one side of the electromagnet 24 along the moving direction of the first camera 1. The two ends of the spring 26 are respectively fixedly connected to the end of the first camera 1 and the inner wall of the housing 2.

[0048] By arranging the spring 26, when the imaging end of the first camera 1 is at the opening 3 of the housing 2 and is affected by strong wind outside, the spring 26 can provide a pressing force for the first camera 1 to prevent the first camera 1 from accidentally sliding into the housing 2 and then accidentally triggering the electromagnet 24.

[0049] Refer to Figure 6 、 Figure 7 、 Figure 9 and Figure 10 :A protection unit 27 is arranged on the housing 2 to cover the opening 3 on the housing 2 after the first camera 1 slides into the housing 2. The protection unit 27 includes a receiving groove 274 opened on the upper part of the housing 2. The receiving groove 274 is an arc-shaped structure. An arc-shaped protective cover 271 is slidably arranged in the receiving groove 274. A third gear 272 is meshed above the first rack 221. A rotating arm 273 fixedly connected to one side of the protective cover 271 is fixedly arranged at the end of the third gear 272. The arc length of the receiving groove 274 is greater than the arc length of the protective cover 271.

[0050] Making the arc length of the receiving groove 274 greater than the arc length of the protective cover 271 ensures that during the process of the first camera 1 sliding into the housing 2, the protective cover 271 can slide in the receiving groove 274, avoiding the protective cover 271 from protruding and hindering the normal movement of the first camera 1. During the sliding process of the first camera 1, the third gear 272 is driven by the first rack 221, and then the rotating arm 273 arranged on the third gear 272 drives the protective cover 271 to rotate. When the first camera 1 completely slides into the housing 2, the protective cover 271 completely seals the opening 3 of the housing 2.

[0051] Working principle: During normal operation and maintenance monitoring, the camera end of the first camera 1 is located at the opening 3 of the outer shell 2. At this time, the camera end of the first camera 1 can monitor the most complete picture and will not be blocked by the outer shell 2, thereby ensuring the monitoring range of the first camera 1 under normal operation and maintenance monitoring. At this time, the second camera 21 is located inside the outer shell 2, and the lower end face of the lifting frame 22 is coplanar with the bottom end face of the outer shell 2. When the first camera 1 is damaged by external impact, since the first camera 1 is slidably set in the outer shell 2 along the extension direction of the opening 3, the camera end of the first camera 1 slides into the outer shell 2 after being acted upon by external forces, thereby reducing the effect of external forces. If the first camera 1 is directly fixed on the outer shell 2, the first camera 1 is slidably set in the outer shell 2, which can further reduce the damage to the first camera 1. When the first camera 1 slides into the housing 2, the lifting frame 22 drives the second camera 21 to descend. The second camera 21 is preferably a panoramic camera. When the second camera 21 descends to the bottom of the housing 2 with the lifting frame 22, the second camera 21 can monitor the surrounding environment more comprehensively. At the same time, since the lifting frame 22 is provided with a reset unit 23, when the lifting frame 22 drives the second camera 21 to descend to the lowest position, the reset unit 23 drives the lifting frame 22 to rise and reset. When the second camera 21 descends to the bottom of the housing 2, it shoots the surrounding environment. Then the reset unit 23 drives the lifting frame 22 to rise again. The second camera 21 is retracted into the housing 2 driven by the lifting frame 2, which not only ensures that the second camera 21 can collect images of the external environment, so that the appearance of the person who carried out the destruction can be accurately collected, but also ensures that the second camera 21 will not be damaged, reducing the cost of later maintenance. It is worth noting that the first camera 1 will be completely retracted into the housing 2 after being hit by the outside world, avoiding secondary damage to the first camera 1.

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
