Description

[0003] At present, it usually includes drone inspection equipment, track inspection equipment and inspection vehicle equipment. Drone inspection equipment is usually used for outdoor inspection, which is easily disturbed by the environment, has a high degree of human intervention, and has a high maintenance cost after damage; because the inspection vehicle travels on the ground, it is greatly restricted by the ground environment, and for some large equipment with a height, it is impossible to collect the full picture of the equipment, and it is often easy to miss important equipment operating parameter information; the track selection equipment is now stable in operation, and because it has a stable track, the probability of collision is extremely low, and the maintenance cost is low, but there are also certain shortcomings. For example, the existing track inspection equipment can usually only move along the track direction. If you want to move in the vertical track direction, you must add a vertical track perpendicular to the original track, which is very cumbersome. At the same time, it will also affect the way the track inspection equipment travels at the intersection of the track, and the degree of desirability is low. However, due to the gaps between some substation equipment, when collecting information, the traditional track inspection equipment cannot monitor the viewing angle between the gaps (usually the track is set along the arrangement direction of the equipment), so a new collection device is urgently needed to solve the above problems.

[0017] The present application is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0018] like Figure 1-11 As shown, a wireless information collection device for substation equipment includes a fixed body 1 and a movable body 2. The fixed body 1 is slidably set on a track. A rotating frame 3 is rotatably provided on the fixed body 1. The straight line where the rotation center of the rotating frame 3 is located is consistent with the length direction of the track. The movable body 2 is slidably set on the rotating frame 3 in a horizontal plane perpendicular to the length direction of the track. A collection module 4 is provided below the movable body 2.

[0019] The fixed body 1 is connected to the track and can move relative to the track to achieve inspection and information collection.

[0020] The rotating frame 3 is set on the fixed body 1, and the rotating frame 3 can swing to a certain extent. The movable body 2 is slidably set on the rotating frame 3, so that it can slide in the direction perpendicular to the track, thereby driving the collection module 4 under the movable body 2 to collect at different angles.

[0021] Compared with traditional track inspection robots, the active body 2 in the present application can move relative to the fixed body 1, thereby increasing the movement path of the collection module 4 without laying too many tracks, thereby better collecting the conditions of the area between two adjacent devices and more accurately collecting the operation information of the equipment.

[0022] It should be noted that the principle of the track inspection robot walking along the track and the working principle of collecting information wirelessly are already common in the industry and are existing technologies, and will not be repeated in this embodiment.

[0023] In some machine embodiments, the acquisition module 4 may be a camera.

[0024] Exemplarily, the camera collects information from each substation equipment and then transmits it. After collecting the video information, it is first converted into digital form (the collected signal is an analog signal), which can usually be achieved through an encoder, and then the signal is transmitted through a transmitting device after modulation. The transmitting device can be a Wi-Fi router, a Bluetooth device, or a wireless transmission device such as a wireless RF module. After that, the receiving end such as the cloud, terminal or control room receives the signal and decodes it to display it on the corresponding display device. Data collection and transmission are already widely used at this stage and are existing technologies, so they will not be described in detail in this embodiment.

[0025] In some further embodiments, the rotating frame 3 includes a V-shaped frame 31, an arc plate 30 and a sliding rod 32. The arc plate 30 is arranged to penetrate the fixed body 1, and the two ends of the arc plate 30 are connected to a group of opposite sides of the V-shaped frame 31. The two ends of the sliding rod 32 are respectively connected to the two sides of the V-shaped frame 31 connected to the arc plate 30; a sliding block 33 is provided on the movable body 2, and the sliding block 33 is slidably set on the sliding rod 32; the other two groups of opposite sides in the V-shaped frame 31 are hinged to the outer wall of the fixed body 1.

[0026] For ease of explanation, the running direction of the fixed body 1 along the track is defined as the front-to-back direction, the moving direction of the movable body 2 is defined as the left-to-right direction, and the arrangement direction of the fixed body 1 and the movable body 2 is defined as the up-down direction.

[0027] The rotating frame 3 can rotate, wherein the two ends of the arc plate 30 are connected to the two side edges in the left and right directions of the V-shaped frame, and the two ends of the sliding rod 32 are also arranged on the two side edges in the left and right directions of the V-shaped frame 31. The sliding block 33 is fixed on the top of the movable body 2, and the sliding block 33 is sleeved on the sliding rod 32 and can slide relative to the sliding rod 32.

[0028] The main function of the rotating frame 3 is to provide a sliding bearing for the movable body 2 .

[0029] In some further embodiments, the fixed body 1 includes a driving chamber and a transmission chamber 11, and the driving chamber and the transmission chamber 11 are spaced apart from each other in an upper and lower manner. A rotating shaft 12 is rotatably provided in the transmission chamber 11, and a first gear 13 and a second gear 140 are provided on the rotating shaft 12. A sliding rack 15 is provided on the bottom side of the transmission chamber 11, and the first gear 13 and the rack 15 are meshed with each other. A tooth groove 300 is provided on the concave side of the arc plate 30, and the second gear 140 and the tooth groove 300 are meshed with each other. A driving frame is slidably provided below the fixed body 1, and the driving frame is connected to the rack 15, and the driving frame is also hinged to the sliding block 33.

[0030] Normally, the track is located in the middle of the top of the fixed body 1. When the movable body 2 moves, the center of gravity of the whole formed by the fixed body 1 and the movable body 2 will be shifted. For this reason, in the present embodiment, when the driving frame drives the sliding block 33 to move relative to the sliding rod 32, the driving frame will synchronously drive the rack 15 to slide, and the rack 15 will drive the first gear 13 to rotate. The rotation of the first gear 13 will drive the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 will synchronously drive the first gear 13 to rotate, thereby driving the arc plate 30 to rotate. That is to say, when the driving frame drives the sliding block 33 to move to the left, the left end of the rotating frame 3 tilts upward, and when the driving frame drives the sliding block 33 to move to the right, the right end of the rotating frame 3 tilts upward. The center of gravity shift caused by the tilt can just offset the degree of center of gravity shift of the whole formed by the fixed body 1 and the movable body 2 to a certain extent, thereby reducing the risk of damage to the track and the components in the fixed body 1 that are interconnected with the guide rail.

[0031] In some further embodiments, the drive frame includes a lead screw 18, a slide rail 170, and a telescopic rod; both ends of the lead screw 18 and the slide rail 170 are connected to the bottom of the two side walls of the transmission chamber 11 and are arranged parallel to each other, the lead screw 18 and the side wall of the transmission chamber 11 are rotatably arranged, a section of the lead screw 18 is transmitted and connected to the motor 181, and a nut seat 180 is screwed on the lead screw 18; a sliding sleeve 17 is provided on the slide rail 170, and the nut seat 180 is connected to the sliding sleeve 17 through a connecting plate 16, and the connecting plate 16 is connected to the rack 15; one end of the telescopic rod is arranged on the connecting plate 16, and the other end is hinged to the sliding block 33.

[0032] When the motor 181 rotates, the lead screw 18 rotates, thereby driving the nut seat 180 to move. The nut seat 180 is connected to the sleeve 17 on the slide rail 170 through the connecting plate 16, thereby driving the sleeve 17 to move. Similarly, through the connecting plate 16, the movement of the drive frame drives the rack 15 to move. Since the movement of the sliding block 33 and the tilting of the sliding rod 32 must occur synchronously, the telescopic rod in the drive frame is connected to the sliding block 33, thereby ensuring that the two actions occur and stop at the same time.

[0033] In some further embodiments, the telescopic rod includes a telescopic sleeve 35, a telescopic shaft 36, and a first spring 34. One end of the telescopic sleeve 35 is connected to the connecting plate 16, and the other end of the sliding sleeve 512 is arranged on the outside of the telescopic shaft 36. The end of the telescopic shaft 36 facing away from the telescopic sleeve 35 is hinged to the sliding block 33. The first spring 34 is located inside the telescopic sleeve 35, one end of which abuts the bottom of the telescopic sleeve 35, and the other end abuts the end face of the telescopic shaft 36.

[0034] An elastically retractable telescopic rod is provided and is hinged to the sliding block 33 to adapt to the change in the distance between the sliding rod 32 and the movable body 2 when the sliding rod 32 is in a tilted state.

[0035] In some further embodiments, there are two first gears 13 , which are respectively located on both sides of the second gear 140 ; ​​there are two racks 15 , which are respectively slidably arranged corresponding to the first gears 13 .

[0036] Two second gears 140 are provided, and two corresponding racks 15 are also provided, which are respectively located on both sides of the first gear 13 ; this ensures the force transmission effect between the rack 15 and the second gear 140 , while avoiding large torsional stress inside the rotating shaft 12 .

[0037] In some further embodiments, a sliding groove 14 is provided at the bottom of the side wall of the transmission chamber 11 , and the rack 15 is slidably disposed in the sliding groove 14 .

[0038] The sliding groove 14 is arranged to be full length from left to right, and the middle bottom is open for connection with the connecting plate 16 .

[0039] In some further embodiments, a driving wheel 50 is provided in the driving cavity, and the driving wheel 50 is rotatably set on a driving seat 51, and the driving seat 51 is fixed on a mounting plate 52. A driving motor 181 is provided on the lower side of the mounting plate 52, and a rotating shaft of the driving wheel 50 passes through the driving seat 51, and a pulley is provided at one end thereof, and the driving motor 181 is connected to the pulley through a belt drive; an inverted T-slot 10 is provided on the fixed body 1, and the inverted T-slot 10 passes through the fixed body 1 along the length direction of the track; two groups of driving wheels 50 and driving seats 51 are provided, and are respectively located on both sides of the inverted T-slot 10.

[0040] The mounting plate 52 is fixed in the driving cavity; the two driving wheels 50 are arranged opposite to each other on the left and right sides, and the rotating shafts on the two driving wheels 50 pass through their corresponding driving seats 51 in opposite directions.

[0041] The driving motor 181 is connected to the driving wheel 50 by means of a belt and a pulley.

[0042] The lower edges of the two driving wheels 50 are respectively used to press the bearing surface 60 of the track. At the same time, the rolling friction between the driving wheels 50 and the bearing surface 60 is the driving force for driving the fixed body 1 and the movable body 2 forward.

[0043] In some further embodiments, the driving seat 51 includes an upper part 510 and a lower part 511, the driving wheel 50 is rotatably set on the upper part 510, and the lower part 511 is set on the mounting plate 52, a sliding shaft 513 is provided on the lower side of the upper part 510, and a sliding sleeve 512 is provided on the upper side of the lower part 511, the sliding shaft 513 and the sliding sleeve 512 are arranged inside the sliding sleeve 512, and a second spring is provided inside the sliding sleeve 512, one end of the second spring abuts against the bottom of the sliding sleeve 512, and the other end abuts against the end face of the sliding shaft 513.

[0044] The driving wheel 50, the mounting plate 52 and the driving seat 51 are relatively common, but the difference between the present embodiment and the traditional structure is that the driving seat 51 includes two parts, namely an upper part 510 and a lower part 511, and the upper part 510 and the lower part 511 are elastically slidably connected to each other so that the driving wheel 50 is always pre-tightened on the track. At the same time, when the driving wheel 50 passes the connection point of the track, the second spring can also play a certain shock-absorbing role.

[0045] In some other embodiments, the upper portions 510 of the two driving seats 51 may be connected together by a rod-like structure to improve stability.

[0046] In some other practical examples, the entire device can reciprocate along a straight line. In actual situations, multiple lines are set up for synchronous information collection.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection created by this application.
