Description

Technical Field

[0001] The present invention relates to the technical field of power distribution room inspection equipment, and in particular to a multifunctional power distribution inspection robot. Background Art

[0002] A distribution room refers to an indoor distribution site with low-voltage loads, which mainly distributes electricity to low-voltage users. It is equipped with medium-voltage incoming lines (with a small number of outgoing lines), distribution transformers and low-voltage distribution devices. In order to ensure the safe operation of the power system in the distribution room, improve work efficiency, enhance work quality and improve the safety management system, it is necessary to conduct regular inspections of the distribution room. The most common equipment for distribution inspections is a track-mounted intelligent inspection robot (a robot that can move autonomously on tracks and can be used for various inspection tasks, such as detecting pipelines, cables, equipment, etc.).

[0003] For a patrol robot used in an underground power distribution room, since the underground environment of the mine is complex and easily affected by impurities such as dust and sand, the track and pan / tilt of the track robot need to be cleaned regularly, otherwise it will affect the normal operation of the equipment; however, the tracks of existing patrol robots are all set up on the top of the mine, which is high and restricted by the internal structure of the mine. Manual cleaning is cumbersome and inconvenient, and the existing patrol robots do not have the ability of self-cleaning, resulting in a decrease in the accuracy of the recognition system. Each cleaning of the patrol robot requires a lot of manpower and material resources, so the functionality of traditional track-type patrol robots needs to be improved. Summary of the invention

[0004] The invention discloses a multifunctional power distribution inspection robot, which improves the use efficiency of existing robots.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multifunctional power distribution inspection robot comprises a guide rail, an inspection platform slidably mounted on the bottom of the guide rail, and a clamping mechanism for surrounding the guide rail and the inspection platform is arranged on the outer side of the inspection platform;

[0007] The interior of the clamping mechanism is provided with a cleaning mechanism for pneumatically cleaning the guide rail and the inspection platform;

[0008] The clamping mechanism is used to clamp the bottom of the guide rail and the outer side of the inspection platform respectively. At the same time, the cleaning mechanism cooperates with the extension and movement of the inspection platform to blow air to remove dust from the surfaces of the guide rail and the inspection platform respectively to prevent dust accumulation.

[0009] By additionally providing a clamping mechanism on the basis of the traditional inspection robot, the inspection pan-tilt and the guide rail are clamped respectively by the rotation of the clamping mechanism; when the clamping mechanism and the guide rail are in contact, the guide rail can be cleaned by wiping and blowing in conjunction with the movement of the inspection pan-tilt and the activation of the cleaning mechanism; when the clamping mechanism and the inspection pan-tilt are in contact, the inspection pan-tilt can be self-cleaned by blowing in conjunction with the extension of the inspection pan-tilt and the activation of the cleaning mechanism. Thus, the cleaning of the traditional inspection robot can be completed through two working modes, thereby improving the functionality of the inspection robot and facilitating cleaning.

[0010] In a preferred embodiment, the clamping mechanism includes a base installed on the outside of the top of the inspection pan-tilt platform, and a rotating part is rotatably installed at both ends of the base, and a double-headed push rod is horizontally installed on one side of the base, and the two ends of the double-headed push rod are respectively in contact with the side surfaces of the two rotating parts, and a telescopic tube is inserted into the bottom of each rotating part, and a bottom part is slidably sleeved on the outside of the end of the telescopic tube, and a group of clamps are symmetrically installed on the side of each bottom part, and the clamps are engaged with the outside of the guide rail.

[0011] By providing two rotating parts structure which are pushed and flipped by double-headed push rods, the rotation of the rotating parts is utilized to drive the bottom part and the clamps on the sides of the bottom part to flip synchronously and engage with the outside of the guide rail, so as to cooperate with the horizontal movement of the inspection platform to wipe and clean the surface of the guide rail, replacing manual cleaning of the inspection robot and greatly improving the cleaning efficiency.

[0012] In a preferred embodiment, the cleaning mechanism includes an air pump fixed to the side of the base, the air pump is connected to the inside of the rotating part, each side of the telescopic tube is penetrated with a first air outlet, the outer side of the bottom part is penetrated with a second air outlet, a spring is fixedly connected between the bottom part and the rotating part, when the spring is in a contracted state, the first air outlet and the second air outlet are blocked, an air duct is penetrated between each group of the clamps, and the air duct is connected to the inside of the telescopic tube, and an exhaust groove is penetrated on the inner surface of each clamp, and the exhaust groove is connected to the inside of the air duct.

[0013] By arranging an exhaust groove and an air guide pipe that are connected through and through the inside of the clamp, when the clamp is engaged with the outside of the guide rail, the operation of the air pump is utilized to transport high-pressure gas into the clamp, and the surface of the guide rail is blown and cleaned by the pressure of the gas ejected from the exhaust groove; when the clamping mechanism is attached to the inspection platform, the telescopic tube is utilized to cooperate with the stretching of the inspection platform, so that the additionally arranged first air outlet that runs through the side of the telescopic tube and the second air outlet that runs through the side of the bottom piece are exposed, thereby changing the air flow path in the air pump, causing high-pressure gas to eject from the first air outlet and the second air outlet, thereby cleaning the surface of the inspection platform, and cooperating with the operation of the clamping mechanism, the guide rail and the inspection platform are cleaned respectively, further improving the cleaning efficiency of the equipment.

[0014] In a preferred solution, an air inlet is provided through the end of the telescopic tube, and the air inlet is located inside the bottom piece and is through-connected with the air guide pipe.

[0015] By providing an air inlet structure connected to the end of the telescopic tube, high-pressure gas is normally introduced into the interior of the clamp through the air inlet. When the telescopic tube moves along the inside of the bottom piece, the air inlet can be blocked to change the air path inside the telescopic tube.

[0016] In a preferred solution, a clamping groove is symmetrically provided on both sides of the bottom of the inspection platform, and a clamping piece is provided on the side of each bottom piece, and the clamping piece is clamped in the inside of the clamping groove.

[0017] By arranging a clamping piece on the side of the bottom piece to cooperate with the clamping groove arranged on the side of the inspection platform, the bottom piece can move synchronously with the extension of the inspection platform, thereby stretching the telescopic tube to expose the first air outlet and the second air outlet.

[0018] As can be seen from the above, the multifunctional power distribution inspection robot provided by the present invention has the following improvements and advantages compared with the prior art:

[0019] First, by providing two rotating parts structures that are pushed and flipped by a double-headed push rod on the basis of the traditional rail-type inspection robot, the rotation of the rotating parts is used to drive the telescopic rod, the bottom part and the clamps on the side of the bottom part to flip synchronously and engage with the outside of the guide rail, so as to cooperate with the horizontal movement of the inspection pan-tilt head to wipe and clean the surface of the guide rail, replacing manual cleaning of the inspection robot, greatly improving the cleaning efficiency, improving the recognition accuracy of the inspection robot, and ensuring the inspection effect.

[0020] Secondly, on the basis of the rotating part and the telescopic rod, an exhaust groove and an air guide pipe are provided inside the clamp. When the clamp is engaged with the outer side of the guide rail, the air pump is used to transport high-pressure gas to the inside of the clamp, and the surface of the guide rail is wiped and blown clean by the pressure of the gas ejected from the exhaust groove in coordination with the movement of the inspection platform. When the rotating part flips over to cause the telescopic tube to fit the inspection platform, the telescopic tube is used to cooperate with the stretching of the inspection platform to expose the first air outlet additionally arranged on the side of the telescopic tube and the second air outlet running through the side of the bottom part, thereby changing the air flow path in the air pump, causing high-pressure gas to eject from the first air outlet and the second air outlet, thereby cleaning the surface of the inspection platform. In coordination with the operation of the clamping mechanism, the working mode can be switched automatically to clean the guide rail and the inspection platform respectively, thereby further improving the functionality and cleaning efficiency of the equipment.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The multifunctional power distribution inspection robot disclosed in the present invention is mainly used in the self-cleaning scenario of an underground track-type inspection robot.

[0033] Reference Figures 1 to 9 A multifunctional power distribution inspection robot comprises a guide rail 1, an inspection platform 2 slidably mounted on the bottom of the guide rail 1, and a clamping mechanism 3 for surrounding the guide rail 1 and the inspection platform 2 is arranged on the outer side of the inspection platform 2;

[0034] A cleaning mechanism 4 for pneumatically cleaning the guide rail 1 and the inspection platform 2 is provided inside the clamping mechanism 3;

[0035] The clamping mechanism 3 is used to clamp the bottom of the guide rail 1 and the outer side of the inspection platform 2 respectively, and the cleaning mechanism 4 cooperates with the extension and movement of the inspection platform 2 to blow and remove dust from the surfaces of the guide rail 1 and the inspection platform 2 respectively.

[0036] The cleaning mechanism 4 is started and introduces high-pressure gas into the interior of the clamping mechanism 3. As the inspection platform 2 reciprocates, the clamping mechanism 3 wipes the surface of the guide rail 1 while blowing and cleaning the surface of the guide rail 1 through the cleaning mechanism 4, thereby completing the cleaning of the guide rail 1. At this time, the user controls the clamping mechanism 3 to rotate again and fit the surface of the inspection platform 2. The cleaning mechanism 4 introduces high-pressure gas into the interior of the clamping mechanism 3, and the clamping mechanism 3 will extend synchronously with the rise and fall of the inspection platform 2, thereby changing the gas flow direction inside the clamping mechanism 3, and blowing and cleaning the surface of the inspection platform 2 through the cleaning mechanism 4.

[0037] Reference Figures 1 to 4 , Figures 6 to 9The clamping mechanism 3 includes a base 301 installed on the outside of the top of the inspection platform 2. A rotating member 302 is rotatably installed at both ends of the base 301. A double-headed push rod 303 is horizontally installed on one side of the base 301. The two ends of the double-headed push rod 303 are respectively in contact with the sides of the two rotating members 302. A telescopic tube 304 is inserted at the bottom of each rotating member 302. A bottom member 305 is slidably sleeved on the outside of the end of the telescopic tube 304. A group of clamps 306 are symmetrically installed on the side of each bottom member 305, and the clamps 306 are clamped on the outside of the guide rail 1. The double-headed push rod 303 is remotely electrically controlled. The battery and remote controller are placed in the inspection platform 2. 4G signals are used (4G signal receivers and transmitters are installed underground). The 4G module is purchased from the existing market. When the double-headed push rod 303 moves, the push rod head extends, pushing the rotating member 302 to rotate, so that the clamp 306 clamps the guide rail 1.

[0038] An adapting groove 7 is provided on the inner side of each of the two rotating members 302 , and the output end of the double-headed push rod 303 is slidably connected to the inside of the adapting groove 7 for connecting the double-headed push rod 303 and the rotating member 302 .

[0039] Reference Figures 1 to 4 , Figures 6 to 9 In a preferred embodiment, the cleaning mechanism 4 includes an air pump 401 fixed to the side of the base 301, the air pump 401 is connected to the inside of the rotating member 302, each section of the side of the telescopic tube 304 is penetrated with a first air outlet 402, the outer side of the bottom member 305 is penetrated with a second air outlet 403, a spring 307 is fixedly connected between the bottom member 305 and the rotating member 302, when the spring 307 is in a contracted state, the first air outlet 402 and the second air outlet 403 are blocked, each group of clamps 306 are connected to each other with an air guide tube 404, and the air guide tube 404 is connected to the inside of the telescopic tube 304, and the inner surface of each clamp 306 is penetrated with an exhaust groove 405, and the exhaust groove 405 is connected to the inside of the air guide tube 404. The air pump 401 is also remotely electrically controlled, powered by a battery, controlled by a remote controller, and transmitted by 4G signals. The control procedures of the double-headed push rod 303 and the air pump 401 all adopt the existing technology.

[0040] Among them, a sponge 308 is sleeved on the outside of each clamp 306, and the exhaust groove 405 runs through the sponge 308. The sponge 308 will contact the outside of the guide rail 1, thereby improving the cleaning efficiency; and the output end of the air pump 401 is connected to a three-way hose 407, and the two ends of the three-way hose 407 are respectively connected to the inside of the two rotating parts 302.

[0041] Furthermore, an air inlet 406 is provided through the end of the telescopic tube 304, a sliding groove 8 is provided on the inner surface of the bottom piece 305, and the outer side of the end of the telescopic tube 304 is slidably connected to the sliding groove 8. Under normal conditions, the air inlet 406 is located inside the bottom piece 305 and is connected to the air duct 404. When the telescopic tube 304 is extended, the telescopic tube 304 will slide horizontally along the inside of the sliding groove 8, thereby causing the air inlet 406 and the air duct 404 to be misaligned, changing the air flow direction inside the telescopic tube 304.

[0042] Reference Figures 1 to 8 In a preferred embodiment, a snap-in groove 5 is symmetrically provided on both sides of the bottom of the inspection platform 2 , and a snap-in member 6 is provided on the side of each bottom member 305 , and the snap-in member 6 is snap-fitted into the inside of the snap-in groove 5 .

[0043] Working principle: When in use, the inspection platform 2 will move back and forth along the top of the guide rail 1 according to a pre-set program (the driving mechanism is a roller connected to the guide rail and driven by an internal motor, which is a known technology of existing inspection robots), and scan and inspect the electrical components inside the distribution room. During long-term operation, dust, sand and other impurities will accumulate on the surface of the guide rail 1 and the inspection platform 2. At this time, the user remotely starts the double-headed push rod 303, causing the output shaft of the double-headed push rod 303 to extend to both ends and push the two rotating parts 302. The rotating part 302 rotates around the base 301, thereby driving the telescopic tube 304 and the bottom part 305 to rotate synchronously until the clamp 306 located on the side of the bottom part 305 is attached to the outside of the guide rail 1. At this time, the air pump 401 starts synchronously and introduces high-pressure gas into the inside of the clamp 306 through the rotating part 302, the telescopic tube 304, the bottom part 305 and the air guide pipe 404. The high-pressure gas introduced into the inside of the clamp 306 will be blown outward through the exhaust groove 405, so that the clamp 306 is accompanied by the reciprocating movement of the inspection pan-tilt head 2, wiping the surface of the guide rail 1 while blowing and cleaning the surface of the guide rail 1 through the exhaust groove 405, thereby completing the cleaning of the guide rail 1.

[0044] Then the user controls the output shaft of the double-headed push rod 303 to reset and retract and pull the two rotating parts 302. The rotating part 302 rotates around the base 301, thereby driving the telescopic tube 304 and the bottom part 305 to reset and rotate, so that the telescopic tube 304 fits the surface of the inspection platform 2, and the clamping part 6 located on the side of the bottom part 305 is clamped into the inside of the clamping groove 5. The user controls the inspection platform 2 to descend. When the inspection platform 2 descends, the bottom part 305 is pulled synchronously through the clamping part 6 and the clamping groove 5. Thereby overcoming the resistance of the spring 307 and causing the contracted telescopic tube 304 to synchronously extend. At this time, the air pump 401 is synchronously started to introduce high-pressure gas into the interior of the telescopic tube 304, and the first air outlet 402 and the second air outlet 403 that were originally blocked will be exposed as the telescopic tube 304 extends, so that the high-pressure gas inside the telescopic tube 304 can be blown out through the first air outlet 402 and the second air outlet 403, thereby changing the air flow direction inside the telescopic tube 304 and blowing and cleaning the surface of the inspection pan-tilt head 2.
