Description

Technical Field

[0001] This utility model relates to the field of power distribution room inspection technology, specifically a power distribution room inspection device. Background Technology

[0002] The power distribution room is of great significance to the stable operation of the power plant. However, there are a lot of devices in the power distribution room that need to be monitored, which is not only time-consuming and labor-intensive, but also has a high risk factor. Therefore, robots that can inspect the power distribution room have been developed to replace traditional manual inspections.

[0003] Chinese patent CN216759898U discloses a lifting device for a power plant substation inspection robot, including a lifting column and a housing. The lifting device is located on the upper part of an automated guided vehicle (AGV), and a camera assembly is installed on the lifting device. The housing includes a top surface, a first side surface, a second side surface, and a back surface, forming a cavity with one end open. The lifting column is installed and fixed inside the cavity. The lifting column includes a column body and a slider that can perform vertical reciprocating motion on the column body. One end of the lifting column is fixedly installed on the top surface of the AGV body, and the other end is fixedly installed on the top surface to ensure the stability of the entire column body.

[0004] However, in the use of this solution and existing technologies, the power distribution room inspection robot is usually mounted on top of a trolley in a liftable manner. The robot is then moved by controlling the movement of the trolley to complete the inspection of power distribution equipment in different locations. Since the trolley used to carry the inspection robot is at a certain height from the ground, when inspecting the equipment in the power distribution room, it is often only possible to inspect the equipment that is higher than the height of the trolley. The equipment in the power distribution room that is lower than the height of the trolley is difficult to inspect due to the obstruction of the trolley, resulting in certain blind spots in the inspection.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a power distribution room inspection device to solve the problem mentioned in the background art that existing power distribution room inspection robots have difficulty inspecting the power distribution equipment below the top of the vehicle body due to the obstruction of the bottom of the vehicle body, resulting in certain blind spots in the inspection.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A power distribution room inspection device includes a camera mounted on top of a trolley for inspecting the power distribution room, and further includes:

[0038] Please see Figure 1-4 This utility model provides a technical solution:

[0039] A power distribution room inspection device includes a camera 102 mounted above a trolley 100 for inspecting the power distribution room, and further includes:

[0040] The second lifting unit 2 is located on one side of the trolley 100 and is used to drive the camera 102 to adjust its height.

[0041] The first lifting unit 1 is located at the upper end of the trolley 100 and is used to drive the second lifting unit 2 to descend to a plane lower than the upper end of the trolley 100.

[0042] As an improvement, such as Figure 1-2 As shown, the first lifting unit 1 includes:

[0043] The first guide frame 11 is fixedly connected to the upper end of the trolley 100;

[0044] The top plate 12 is fixedly connected to the upper end of the first guide frame 11;

[0045] The first screw 13 is rotatably inserted into the first guide frame 11. The top plate 12 is equipped with a first drive motor 14 whose drive end is connected to the upper end of the first screw 13 for driving the first screw 13 to rotate.

[0046] The base plate 16 is fixedly connected to the upper end of the trolley 100 and located at the lower part of the first guide frame 11. The base plate 16 is rotatably sleeved on the outside of the first screw 13 to limit the lower end of the first screw 13.

[0047] Furthermore, such as Figure 2 As shown, the first lifting unit 1 further includes:

[0048] The lifting beam 15 is slidably inserted into the first guide frame 11. The first guide frame 11 is provided with a first guide groove 111 for guiding the movement of the lifting beam 15. The second lifting unit 2 is connected to one end of the lifting beam 15.

[0049] The first threaded hole 151 is provided inside the lifting beam 15 and located outside the first screw 13. The lifting beam 15 is threadedly connected to the first screw 13 and is used to drive the second lifting unit 2 to lift.

[0050] As an improvement, such as Figure 3-4 As shown, the second lifting unit 2 includes:

[0051] The second guide frame 21 has a second guide groove 211 inside it;

[0052] The second drive motor 22 is installed on the upper end of the second guide frame 21;

[0053] The second screw 23 is rotatably disposed inside the second guide frame 21, and the upper end of the second screw 23 is connected to the drive end of the second drive motor 22;

[0054] The lifting plate 25 is threadedly connected to the outside of the second screw 23, and the lifting plate 25 is provided with a second threaded hole 251 that is adapted to the thread on the outside of the second screw 23.

[0055] The support platform 26 is fixedly connected to one end of the lifting plate 25 located outside the second guide groove 211, and is used to support the camera 102.

[0056] Furthermore, a guide hole 252 is provided inside the lifting plate 25 and on one side of the second threaded hole 251;

[0057] The guide hole 252 is slidably inserted with a guide shaft 24 for guiding the up and down movement of the lifting plate 25 in conjunction with the second guide groove 211. The upper and lower ends of the guide shaft 24 are fixedly connected to the upper and lower ends of the second guide groove 211, respectively.

[0058] Among them, such as Figure 4 As shown, a limiting block 231 is fixedly connected to the lower end of the second screw 23 and inside the second guide frame 21;

[0059] The second guide frame 21 has a limiting hole 212 inside and outside the limiting block 231, which is used to limit the bottom of the second screw 23 to prevent the bottom of the second screw 23 from shifting during rotation.

[0060] One side of the middle part of the second guide frame 21 is fixedly connected to one end of the lifting beam 15, and the part of the second guide frame 21 located below the lifting beam 15 is adapted to the height of the trolley 100.

[0061] It should be added that the upper front part of the car 100 in this utility model is equipped with a detector head 101 for viewing obstacles directly in front of the car 100. The car 100 drives automatically in the power distribution room through an internally set program.

[0062] It should also be noted that the camera 102 in this utility model transmits the real-time working status of the power distribution equipment captured during the inspection process to the data analysis terminal of the computer via signal transmission. If the data analysis terminal of the computer detects an abnormality in the working status of the power distribution equipment captured by the camera 102, the alarm sounding device connected to the computer will sound an alarm to ensure that the staff can arrive at the power distribution equipment site in time to repair the power distribution equipment.

[0063] It should be noted that: in the specific implementation process of this utility model, if... Figure 2-4 As shown, when it is necessary to inspect the power distribution equipment in the power distribution room, the trolley 100 is driven into one side of the row of power distribution equipment, so that the forward direction of the trolley 100 is parallel to the direction of the power distribution equipment arrangement. The camera 102 is turned on. Initially, the camera 102 is close to the bottom of the second guide groove 211, and the lifting beam 15 is located on the upper outer side of the first screw 13. When inspecting the power distribution equipment in the lower area of ​​the trolley 100, the first drive motor 14 is started. The first drive motor 14 drives the first screw 13 to rotate. The first screw 13 drives the lifting beam 15 along the first guide groove 111 through the thread tangential force between the first screw 13 and the first threaded hole 151. The lifting beam 15 moves downward, causing the second guide frame 21 to move downward, so that the camera 102 moves downward to near the ground. Then, the second drive motor 22 is started, which drives the second screw 23 to rotate. The second screw 23 drives the lifting plate 25 to move upward along the second guide groove 211 under the action of the thread tangential force between the second screw and the second threaded hole 251. The lifting plate 25 drives the camera 102 to move upward through the support platform 26, so that the camera 102 can inspect the working status of one of the power distribution devices, thereby achieving the effect of inspecting the power distribution devices below the side of the car 100, with no blind spots in the inspection process.

[0064] like Figure 3-4As shown, for some power distribution equipment that is higher than the second guide frame 21, after the lifting plate 25 is brought to the top of the second guide groove 211 by the second screw 23, it is impossible to further inspect the power distribution equipment above the second guide frame 21. Therefore, when the lifting plate 25 is brought to the top of the second guide groove 211 by the second screw 23, the first drive motor 14 is controlled to rotate in the opposite direction. The first drive motor 14 drives the lifting beam 15 to move upward through the thread on the outside of the first screw 13 and the first threaded hole 151. The lifting beam 15 drives the camera 102 to move upward further through the second guide frame 21, so that the camera 102 can inspect the power distribution equipment that is higher than the second guide frame 21, and the inspection range is wide.

[0065] After the inspection of one power distribution device is completed, the trolley 100 drives the inspection robot forward to the side of the next power distribution device. When inspecting the next power distribution device, the inspection can be carried out from the top of the side of the power distribution device downwards, without having to reset the camera 102 after each inspection.

[0066] like Figure 2 As shown, this utility model, by setting a first screw 13 and a second screw 23, and by setting a relatively short second guide frame 21, enables the inspection of higher power distribution equipment. Compared with the prior art, which sets a higher and independent second guide frame 21 on the top of the trolley 100, this utility model can adjust the relative height between the second guide frame 21 and the ground, making it easier for the trolley 100 to pass through the door frame of one power distribution room to the next power distribution room.
