Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power grid inspection, especially to a power grid inspection device. BACKGROUND

[0002] As an important part of the power grid, the distribution network directly faces the end users and is closely related to the production and life of the general public, and is an important infrastructure for local economic security and national economy and people's livelihood. With the rapid development of the power grid and the continuous improvement of urban cable rate, higher requirements are put forward for the safe and reliable operation of overhead lines in low-voltage distribution networks.

[0003] In terms of operation inspection, there is no intelligent inspection system at present, and only manual inspection can be relied on. The PMS system reports the inspection plan and issues the inspection task, and the operation and maintenance personnel arrive at the scene to perform the inspection task. During the inspection process, the appearance of the cable needs to be checked to check whether there is damage, rust or other abnormal conditions. However, in the prior art, only a camera carried by a drone is usually used to take pictures of the surface of the cable, and then the collected pictures are analyzed to understand whether the cable is damaged.

[0004] Through retrieval, a kind of image acquisition device of electric power inspection in Chinese patent (announcement number: CN211869713U) is obtained, more clear image is obtained by pushing image acquisition camera to be close to power grid, and balance mechanism is kept balance, avoid the gravity imbalance caused by the extension of image acquisition camera.

[0005] However, for the cable installed outdoors, as the use time increases, a large amount of dust gradually accumulates on the surface of the cable. At this time, the dust adhering to the surface of the cable causes the camera to be unable to collect the real image of the surface of the cable, that is, it is impossible to intuitively understand whether scratches or deformation appear on the surface of the cable, so that the inspection effect is poor.

[0006] Therefore, a power grid inspection device is proposed. SUMMARY

[0007] The utility model aims at providing a power grid inspection device, which can solve the problem of being unable to intuitively collect the real picture of the surface of the cable due to dust adhering to the surface of the cable.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a power grid inspection device, comprising a connecting plate, a mounting bracket is fixedly installed on the bottom wall of the connecting plate, a bayonet is formed on the mounting bracket, and a camera is uniformly installed on the mounting bracket; the cameras are uniformly circumferentially distributed around the bayonet.

[0009] The side wall of the mounting frame is provided with a guide groove, which is arc-shaped, and a sliding plate is slidably installed in the guide groove, and a sponge is installed on the sliding plate, which is ring-shaped, and the sponge is provided with a split opening matched with the bayonet, and the mounting frame is provided with a cavity, and a water tank is installed on the mounting frame and extends into the cavity, and the side wall of the cavity is uniformly provided with a drain pipe communicated with the outside, and the drain pipe is matched with the sponge.

[0010] A disc is rotatably installed on the outer wall of the mounting frame, a push rod is installed on the side wall of the disc, and a driving mechanism matched with the disc is arranged on the mounting frame, a stop rod matched with the push rod is fixedly installed on the top wall of the sliding plate, and an elastic member is installed between the sliding plate and the guide groove.

[0011] Firstly, the mounting frame and the unmanned aerial vehicle are connected together through the connecting plate, so that the whole inspection device can be moved together by the unmanned aerial vehicle, when the device moves above the cable, the cable is perpendicular to the surface of the mounting frame and the bayonet is aligned with the cable, then the unmanned aerial vehicle drives the mounting frame to move downward, so that the cable can pass through the bayonet, and under the action of the split opening, the cable passing through the bayonet is wrapped by the sponge; at this time, the output end of the water tank is opened, the water in the water tank flows into the cavity, and finally is discharged into the sponge through the drain pipe, the damp sponge can wipe the surface of the cable clean during the movement of the inspection device, so as to ensure that the camera can collect clear pictures and the real situation of the cable, and plays a role in improving the inspection effect.

[0012] Under the action of the driving mechanism, the disc drives the push rod to rotate, when the push rod is at the center of the height of the disc, the push rod contacts with the stop rod, then the disc continues to drive the push rod to rotate, at this time the push rod pushes the stop rod, the stop rod drives the sliding plate to rotate, and the push rod moves upward along the stop rod, finally the push rod and the stop rod are out of contact, at this time the elastic member pulls the sliding plate to reset, therefore under the action of the driving mechanism, the disc can drive the sliding plate to do reciprocating motion in the guide groove, and the sponge scrapes on the surface of the cable during the reciprocating motion of the sliding plate, so as to improve the cleaning effect of the surface of the cable.

[0013] Preferably, the driving mechanism comprises a rotating rod rotatably inserted into the side wall of the cavity, and a impeller is fixedly installed on the part of the rotating rod located in the cavity, and one end of the rotating rod located outside the cavity is fixedly connected with the center of the disc.

[0014] When the water flows along the cavity, the water flow impacts the impeller, at this time the impeller drives the rotating rod to rotate, so as to realize the driving of the disc to rotate, and the continuous rotation of the disc is realized by driving the impeller with the water flow.

[0015] Preferably, a cavity is formed in the elastic member, and a gas hole is formed in the side wall of the cavity, and the gas hole is used for blowing air to the surface of the sponge.

[0016] The sponge and camera are located on opposite sides of the mounting bracket. A one-way valve is installed on the side wall of the mounting bracket, and the output end of the one-way valve is connected to the cavity.

[0017] During the stretching and recovery process of the elastic element, the cavity intermittently exhausts air through the vent and draws air from the outside through the one-way valve. When the cavity exhausts air through the vent, the airflow impacts the sponge, thereby blowing away the dust attached to the surface of the sponge and playing the role of automatically cleaning the sponge.

[0018] Preferably, an elastic rope is fixedly installed inside the air hole, and an impact block is installed at the end of the elastic rope for impacting the sponge.

[0019] During the recovery process of the elastic component, the recovery speed changes with the change in deformation, and therefore the gas flow rate discharged from the vent also changes. During the vent discharge process, the airflow impacts the impact block. At this time, the impact block installed at the end of the elastic rope shakes and impacts the sponge, which can make the sponge shake and shake off the dust on the surface of the sponge, thus playing a role in assisting the airflow to clean the sponge.

[0020] Preferably, two water tanks are symmetrically installed on the side wall of the mounting frame, and a U-shaped pipe is provided between the two water tanks.

[0021] By setting up a U-shaped tube, the force on the drone can be evenly distributed during the flight of the drone-driven inspection device, thus ensuring that the inspection device can fly normally.

[0022] Preferably, the drain pipe is a corrugated pipe.

[0023] Since the sponge needs to move with the skateboard, the use of flexible corrugated pipes to make the drainage pipes ensures that the sponge can move normally.

[0024] Preferably, a sleeve is fitted onto the push rod.

[0025] When a sleeve is fitted onto the push rod, both the push rod and the stop rod are subjected to rolling friction during the pushing process, which reduces the resistance encountered by the stop rod in moving the skateboard and ensures that the skateboard can move normally.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. This application, by setting up a mounting frame, a sliding plate, a sponge, and a drive mechanism, enables the sliding plate to reciprocate in the guide groove via a disc under the action of the drive mechanism. During the reciprocating motion of the sliding plate, the sponge scrapes the cable surface, thereby improving the cleaning effect on the cable surface. The damp sponge can wipe the cable surface clean as it moves with the inspection device, thereby ensuring that the camera can capture clear images and the true condition of the cable, thus improving the inspection effect.

[0028] 2. By setting up an elastic element, a cavity, an air hole, and a one-way valve, this application can stretch the elastic element during the movement of the skateboard, so that the cavity can draw in air through the one-way valve and then exhaust air through the air hole. The air discharged from the air hole impacts the sponge, thereby washing away the dust attached to the sponge and keeping the sponge clean. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 7 This utility model provides a technical solution:

[0041] A power grid inspection device includes a connecting plate 1, a mounting frame 2 fixedly installed on the bottom wall of the connecting plate 1, a slot provided on the mounting frame 2, and cameras 3 evenly installed on the mounting frame 2, with the cameras 3 evenly distributed circumferentially around the slot.

[0042] The mounting bracket 2 has a guide groove on its side wall. The guide groove is arc-shaped. A slide plate 4 is slidably installed in the guide groove. A sponge 5 is installed on the slide plate 4. The sponge 5 is annular and has a slit that matches the snap-fit. The mounting bracket 2 has a cavity 6. The mounting bracket 2 has a water tank 7 with its output end extending into the cavity 6. Drain pipes 8 that communicate with the outside are evenly inserted into the side wall of the cavity 6. The drain pipes 8 match the sponge 5.

[0043] A disc 9 is rotatably mounted on the outer wall of the mounting frame 2. A push rod 10 is mounted on the side wall of the disc 9. The mounting frame 2 is provided with a drive mechanism that cooperates with the disc 9. A stop rod 11 that cooperates with the push rod 10 is fixedly mounted on the top wall of the slide plate 4. An elastic element 12 is installed between the slide plate 4 and the guide groove.

[0044] First, the mounting bracket 2 is connected to the drone via the connecting plate 1, allowing the drone to move the entire inspection device together. When the device moves above the cable, the cable is perpendicular to the surface of the mounting bracket 2, and the clamp is aligned with the cable. Then, the drone moves the mounting bracket 2 downward, allowing the cable to pass through the clamp. Under the action of the crack, the cable passing through the clamp is wrapped by the sponge 5. At this time, the output end of the water tank 7 is opened, and the water in the water tank 7 flows into the cavity 6, and finally is discharged into the sponge 5 through the drain pipe 8. The damp sponge 5 can wipe the surface of the cable clean as the inspection device moves, thus ensuring that the camera 3 can capture clear images and the true condition of the cable, thereby improving the inspection effect.

[0045] Under the action of the drive mechanism, the disc 9 drives the push rod 10 to rotate. When the push rod 10 is at the center of the height of the disc 9, the push rod 10 contacts the stop rod 11. Then the disc 9 continues to drive the push rod 10 to rotate. At this time, the push rod 10 pushes the stop rod 11, the stop rod 11 drives the slide plate 4 to rotate, and the push rod 10 moves up along the stop rod 11. Finally, the push rod 10 and the stop rod 11 disengage. At this time, the elastic element 12 pulls the slide plate 4 to reset. Therefore, under the action of the drive mechanism, the disc 9 can drive the slide plate 4 to reciprocate in the guide groove. During the reciprocating motion of the slide plate 4, the sponge 5 scrapes the surface of the cable, thereby improving the cleaning effect on the surface of the cable.

[0046] Specifically, such as Figure 6 As shown, the driving mechanism includes a rotating rod 13 rotatably inserted into the side wall of the cavity 6. An impeller 14 is fixedly installed on the part of the rotating rod 13 located inside the cavity 6. The end of the rotating rod 13 located outside the cavity 6 is fixedly connected to the center of the disk 9.

[0047] By adopting the above technical solution, when water flows along the cavity 6, the water flow impacts the impeller 14. At this time, the impeller 14 drives the rotating rod 13 to rotate, thereby realizing the function of driving the disk 9 to rotate. Furthermore, the impeller 14 can be continuously rotated by the water flow, thus enabling the disk 9 to rotate continuously.

[0048] Specifically, such as Figure 5 As shown, the elastic element 12 has a cavity 15, and the side wall of the cavity 15 has an air hole 16, which is used to blow air onto the surface of the sponge 5.

[0049] The sponge 5 and the camera 3 are distributed on opposite sides of the mounting frame 2. A one-way valve 17 is provided on the side wall of the mounting frame 2, and the output end of the one-way valve 17 is connected to the cavity 15.

[0050] By adopting the above technical solution, during the stretching and recovery process of the elastic element 12, the cavity 15 intermittently exhausts air outward through the air hole 16 and draws air from the outside through the one-way valve 17. When the cavity 15 exhausts air outward through the air hole 16, the airflow impacts the sponge 5, thereby blowing away the dust attached to the surface of the sponge 5, thus playing the role of automatically cleaning the sponge 5.

[0051] Specifically, such as Figure 5 As shown, an elastic rope 18 is fixedly installed inside the air hole 16, and an impact block 19 is installed at the end of the elastic rope 18. The impact block 19 is used to impact the sponge 5.

[0052] By adopting the above technical solution, during the recovery process of the elastic element 12, the recovery speed also changes with the change of deformation, so the gas flow rate discharged from the vent 16 also changes; during the exhaust process of the vent 16, the airflow impacts the impact block 19, and at this time the impact block 19 installed at the end of the elastic rope 18 shakes and impacts the sponge 5, thereby making the sponge 5 shake and shaking off the dust on the surface of the sponge 5, which plays the role of assisting the airflow to clean the sponge 5.

[0053] Specifically, such as Figure 1 As shown, two water tanks 7 are symmetrically installed on the side wall of the mounting frame 2, and a U-shaped pipe 20 is provided between the two water tanks 7.

[0054] By adopting the above technical solution, the U-shaped tube 20 can ensure that the drone is subjected to uniform force during the flight of the inspection device, thus ensuring that the inspection device can fly normally.

[0055] Specifically, such as Figure 1 As shown, the drain pipe 8 is a corrugated pipe.

[0056] By adopting the above technical solution, since the sponge 5 needs to move with the slide plate 4, the use of a flexible corrugated pipe to make the drainage pipe 8 ensures that the sponge 5 can move normally.

[0057] Specifically, such as Figure 6 As shown, a sleeve 21 is fitted onto the push rod 10.

[0058] By adopting the above technical solution, when the sleeve 21 is sleeved on the push rod 10, both the push rod 10 and the stop rod 11 are subjected to rolling friction during the process of pushing the stop rod 11, which reduces the resistance encountered by the stop rod 11 in moving the slide plate 4 and ensures that the slide plate 4 can move normally.

[0059] Working principle: First, the mounting bracket 2 is connected to the drone via the connecting plate 1, allowing the drone to move the entire inspection device together. When the device moves above the cable, the cable is perpendicular to the surface of the mounting bracket 2 and the clamp is aligned with the cable. Then, the drone moves the mounting bracket 2 downward, allowing the cable to pass through the clamp. Under the action of the gap, the cable passing through the clamp is wrapped by the sponge 5. At this time, the output end of the water tank 7 is opened, and the water in the water tank 7 flows into the cavity 6, and finally is discharged into the sponge 5 through the drain pipe 8. The damp sponge 5 can wipe the surface of the cable clean as the inspection device moves, thus ensuring that the camera 3 can capture clear images and the true condition of the cable, thereby improving the inspection effect.

[0060] Under the action of the drive mechanism, the disc 9 drives the push rod 10 to rotate. When the push rod 10 is at the center of the height of the disc 9, the push rod 10 contacts the stop rod 11. Then the disc 9 continues to drive the push rod 10 to rotate. At this time, the push rod 10 pushes the stop rod 11, the stop rod 11 drives the slide plate 4 to rotate, and the push rod 10 moves up along the stop rod 11. Finally, the push rod 10 and the stop rod 11 disengage. At this time, the elastic element 12 pulls the slide plate 4 to reset. Therefore, under the action of the drive mechanism, the disc 9 can drive the slide plate 4 to reciprocate in the guide groove. During the reciprocating motion of the slide plate 4, the sponge 5 scrapes the surface of the cable, thereby improving the cleaning effect on the surface of the cable.

[0061] When water flows along the cavity 6, the water flow impacts the impeller 14. At this time, the impeller 14 drives the rotating rod 13 to rotate, thereby driving the disk 9 to rotate. Furthermore, the impeller 14 can be continuously rotated by the water flow, thus enabling the disk 9 to rotate continuously.

[0062] During the stretching and recovery process of the elastic element 12, the cavity 15 intermittently exhausts air through the vent 16 and draws air from the outside through the one-way valve 17. When the cavity 15 exhausts air through the vent 16, the airflow impacts the sponge 5, thereby blowing away the dust attached to the surface of the sponge 5 and playing the role of automatically cleaning the sponge 5.

[0063] During the recovery process of the elastic element 12, the recovery speed changes with the change in deformation, thus altering the gas flow rate discharged from the vent 16. During the exhaust process of the vent 16, the airflow impacts the impact block 19. At this time, the impact block 19, installed at the end of the elastic rope 18, shakes and impacts the sponge 5, causing the sponge 5 to vibrate and dislodge dust from its surface, thus assisting the airflow in cleaning the sponge 5. When the sleeve 21 is fitted onto the push rod 10, both the push rod 10 and the stop rod 11 experience rolling friction during the pushing of the stop rod 11, reducing the resistance encountered by the stop rod 11 in moving the slide plate 4, and ensuring the normal movement of the slide plate 4. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
