Description

Technical Field

[0001] This invention relates to the field of substation safety inspection technology, and in particular to a substation construction safety inspection device. Background Technology

[0002] With the continuous development of the power industry, the construction and maintenance of substations have become increasingly important. During substation construction, safety inspections are crucial, as they can promptly identify potential safety hazards, ensuring the safety of construction personnel and the normal operation of equipment. Currently, most substation construction projects utilize automated inspection vehicles for inspections.

[0003] During the construction phase of a substation, there is a lot of dust and other debris, which often causes the cameras on inspection vehicles to accumulate dust and debris, thus affecting the inspection effectiveness. To address this issue, patent document CN219577177U discloses an adjustment device that facilitates flexible adjustment of the intelligent inspection camera in a substation. This document can clean the camera. However, although the above technical solution can clean the camera, its cleaning structure is also exposed to the outside. Therefore, contamination of the cleaning structure will affect its cleaning effect on the camera.

[0004] Meanwhile, the aforementioned technical documents use water spraying to clean the camera. This method cannot remove stubborn stains such as oil on the camera surface. Furthermore, if the cleaning structure of the device becomes contaminated during cleaning and is not cleaned or replaced in time, stains will remain, affecting the image quality of the camera.

[0005] In addition, although there are existing inspection vehicles that can store cameras, and the cameras are generally rigidly connected to the mounting plate, the cameras are easily damaged due to the vibration or bumps of the inspection vehicle when they are stored. If the cameras are elastically connected to the mounting plate, the inspection effect will be poor due to camera shaking during the inspection process.

[0006] Therefore, in order to improve the quality of the device's camera and the accuracy and efficiency of the inspection work, this invention provides a substation construction safety inspection device. Summary of the Invention

[0007] The purpose of this invention is to solve the problems existing in the prior art and to propose a substation construction safety inspection equipment, including a protective box with a cover plate, a support plate installed inside the protective box and controlled by a lifting mechanism, a camera installed on the top of the support plate, a support base set inside the protective box through a connecting structure, a cleaning block fixedly connected to the rear end of the support base, a winding roller rotatably connected to the upper and lower ends of the support base, and a cleaning cloth wrapped around the rear end of the cleaning block installed on the outside of the winding roller.

[0008] The connection structure includes a slide groove at the lower end of the inside of the protective box. A connecting frame is slidably connected to the side wall of the slide groove via a spring rod. Trapezoidal blocks are fixedly connected to both sides of the upper rear part of the connecting frame. A second trapezoidal block, which works in conjunction with the first trapezoidal block, is installed at the middle of the lower end of the support plate.

[0009] Uprights are fixedly connected to both sides of the upper front part of the connecting frame. Guide grooves are opened on the side of the two uprights that are close to each other. A connecting rod is installed at the front end of the support base. Guide blocks that cooperate with the guide grooves are provided at both ends of the connecting rod.

[0010] The protective box has a guide rail fixedly connected to its front end. A connecting frame is connected to the guide rail via a slider. A connecting block is connected to the inside of the connecting frame via a guide post. The connecting block is fixedly connected to the side of the connecting rod.

[0011] The lifting mechanism moves the support plate downward into the protective box. Trapezoidal block two moves the support base through trapezoidal block one and attaches it to the lens of the camera. The support base moves up and down through the guide rail. The cleaning cloth at the rear of the cleaning block cleans the camera.

[0012] The upper winding roller is connected to a ratchet that rotates the winding roller. A pawl structure engages with the ratchet on its lower side. Several levers that are evenly distributed in a circle are fixedly connected to the side of the ratchet away from the support. A trapezoidal lever block that works with the levers is slidably connected to the upper part of the protective box.

[0013] Preferably, the inclined surface of the lever faces forward, and the lever is installed in the mounting groove opened on the upper part of the protective box via a spring rod. When the support seat slides backward, the inclined surface of the lever is moved by the lever to push the lever upward to avoid driving the winding roller to rotate. When the support seat is reset forward under the drive of the connecting structure, the lever contacts the straight surface of the rear end of the lever, and drives the winding roller to rotate under the connection of the ratchet, thereby replacing the cleaning cloth at the rear end of the cleaning block.

[0014] Preferably, the support plate includes a fixed plate installed on its upper part, the fixed plate is connected to the camera, positioning rods are fixedly connected to the four corners of the lower end of the fixed plate, and connection holes are opened at the four corners of the upper end of the support plate, and the positioning rods are inserted into the connection holes.

[0015] Preferably, the upper rear side of the inside of the protective box has a groove for engaging the fixing plate; a buffer spring is installed on the side of the support plate and the fixing plate that are close to each other, and the elasticity of the buffer spring is used to buffer the impact force from the vertical direction; the positioning rod is inserted into the connection hole with a gap fit.

[0016] Preferably, the upper rear side of the protective box has a storage groove that extends into the slot. A U-shaped locking block is slidably connected inside the storage groove. Locking grooves that cooperate with the locking block are opened on both sides of the fixing plate. The side of the locking block away from the fixing plate is fixedly connected to the storage groove by a spring rod.

[0017] Preferably, the lower end of the locking block has inclined grooves on both the upper and lower sides for pushing the locking block to slide, and the upper end of the locking block extends into the groove.

[0018] Preferably, the cleaning block has a semi-circular cylindrical structure, the side of the cleaning block that contacts the cleaning cloth is made of rubber, and the cleaning block is installed inside the support base by an elastic element.

[0019] Preferably, the guide groove is provided with three vertical tracks, the upper and lower tracks are vertically corresponding and located behind the middle track, and the middle track is connected to the remaining two tracks through an oblique groove.

[0020] Preferably, a triangular support block is fixedly connected to the lower end of the protective box, with the apex of the triangular support block pointing downwards. A base is provided below the protective box, and the support block is hinged to the upper end of the base. An electric push rod is hinged to the upper end of the base, and the upper end of the electric push rod is hinged to the front part of the lower end of the support block. Both sides of the base are rotatably connected to traveling wheels.

[0021] Compared with existing technologies, the advantages of this invention are as follows: 1. When cleaning the camera, this invention controls the up-and-down movement of the cleaning block by driving the guide rail and slider. The cooperation of the guide groove and guide block causes the cleaning block to move slightly backward during the up-and-down movement, increasing the pressure between the cleaning block and the camera, effectively removing stubborn stains from the camera surface. Simultaneously, the lever and lever work together to drive the winding roller to rotate via a ratchet and pawl structure, promptly rotating the cleaning cloth to ensure its cleanliness and achieve good results with each cleaning, thus guaranteeing image quality.

[0022] 2. When the camera is stowed, this invention utilizes a positioning rod and a buffer spring to provide cushioning protection. When the protective case is subjected to external impact, the buffer spring absorbs the impact energy through its own elastic deformation, reducing the impact force on the camera and protecting it from damage. Furthermore, through the connecting hole with a diameter larger than that of the positioning rod, impact forces from the sides and front and rear can be buffered, improving the protective effect of the device.

[0023] 3. When the camera is raised, the present invention can stably lock the position of the camera through the cooperation of the locking block and the locking groove and the stable support of the reset mechanism. The camera can also remain stable when it is disturbed by external factors, ensuring that the captured image is clear and stable. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-3 A substation construction safety inspection device includes a protective box 1 with a cover, a support plate 13 installed inside the protective box 1 and controlled by a lifting mechanism, a camera 11 mounted on the top of the support plate 13, a support base 2 provided inside the protective box 1 via a connecting structure 4, a cleaning block 21 fixedly connected to the rear end of the support base 2, and a winding roller 22 rotatably connected to each of the upper and lower ends of the support base 2. A cleaning cloth 23 wrapped around the rear end of the cleaning block 21 is installed on the outside of the winding roller 22. The protective box 1 of this invention is used to store and clean the camera 11. The lifting mechanism moves the camera 11 downwards, so that the camera 11 moves into the protective box 1, at which time the cleaning cloth 23 can clean the lens of the camera 11.

[0037] It should be noted that the camera 11 is equipped with a gimbal at the bottom, which allows the camera 11 to freely adjust the shooting angle, and the lifting mechanism is a scissor-type lifting structure.

[0038] Reference Figure 1 and Figure 9 A triangular support block 7 is fixedly connected to the lower end of the protective box 1, with the tip of the triangular support block 7 pointing downwards. A base 71 is provided below the protective box 1. The support block 7 is hinged to the upper end of the base 71. An electric push rod 72 is hinged to the upper end of the base 71. The upper end of the electric push rod 72 is hinged to the front part of the lower end of the support block 7. Both sides of the base 71 are rotatably connected to traveling wheels 73.

[0039] The angle of the protection box 1 can be adjusted by the telescopic movement of the electric push rod 72, and the traveling wheel 73 can drive the invention to move within the construction area of ​​the substation.

[0040] Reference Figure 4 , Figure 6 The connecting structure 4 includes a slide groove 41 located at the lower end of the interior of the protective box 1. A connecting frame 42 is slidably connected to the side wall of the slide groove 41 via a spring rod 44. Trapezoidal blocks 43 are fixedly connected to both sides of the upper rear part of the connecting frame 42. A trapezoidal block 431 that cooperates with trapezoidal block 43 is installed at the middle of the lower end of the support plate 13. When the support plate 13 moves downward, the connecting frame 42 moves backward due to the cooperation between trapezoidal block 431 and trapezoidal block 43. When the two separate, the connecting frame 42 returns to its initial position under the action of the spring rod 44.

[0041] Reference Figure 6 The upper front of the connecting frame 42 is fixedly connected to two uprights 45. The two uprights 45 are provided with guide grooves 451 on one side close to each other. The front end of the support base 2 is equipped with a connecting rod 453. The two ends of the connecting rod 453 are provided with guide blocks 452 that cooperate with the guide grooves 451.

[0042] Reference Figure 6 and Figure 8 The protective box 1 has a guide rail 47 fixedly connected to its front end. A connecting frame 461 is connected to the guide rail 47 via a slider 471. A connecting block 46 is connected to the inside of the connecting frame 461 via a guide post 462. The connecting block 46 is fixedly connected to the side of the connecting rod 453. The guide rail 47 drives the connecting block 46 to move up and down via the slider 471. The connecting block 46 can drive the support base 2 to move up and down synchronously. At this time, under the cooperation of the guide block 452 and the guide groove 451, the support base 2 can move up and down along the trajectory of the guide groove 451.

[0043] It should be noted that the guide groove 451 is provided with three vertical tracks. The upper and lower tracks are vertically corresponding and located behind the middle track. The middle track is connected to the remaining two tracks through an oblique groove. At the same time, the cleaning block 21 is a semi-circular cylindrical structure. The side of the cleaning block 21 that contacts the cleaning cloth 23 is made of rubber. The cleaning block 21 is installed inside the support base 2 by an elastic element. The above-mentioned track setting of the guide groove 451 allows the cleaning block 21 to increase the contact force with the camera 11 under the action of the elastic element when the support base 2 moves upward or downward, thereby increasing the cleaning effect of the camera 11. Moreover, the rubber material of the cleaning block 21 ensures that it will not damage the camera 11. Its semi-circular structure allows the cleaning cloth 23 at different positions to clean the camera 11 when cleaning the upper and lower parts of the camera 11.

[0044] The lifting mechanism moves the support plate 13 downward into the protective box 1. The trapezoidal block 431 at the bottom of the support plate 13 drives the connecting frame 42 to move backward through the trapezoidal block 43. The connecting frame 42 drives the support base 2 to move through the upright 45, so that the cleaning cloth 23 at the rear of the cleaning block 21 is attached to the lens of the camera 11. The support base 2 moves up and down through the guide rail 47, and the cleaning cloth 23 at the rear of the cleaning block 21 cleans the camera 11.

[0045] A ratchet 3 is connected to one side of the upper winding roller 22 to rotate the winding roller 22. A pawl structure 31 is engaged on the lower side of the ratchet 3. Several levers 32 that are evenly distributed in a circle are fixedly connected to the side of the ratchet 3 away from the support seat 2. A trapezoidal lever block 33 that works with the levers 32 is slidably connected to the upper part of the inside of the protective box 1.

[0046] Reference Figure 2 , Figure 3 and Figure 7The slanted face of the lever 33 faces forward and is installed in the mounting groove 331 on the upper part of the protective box 1 via the spring rod 332. When the support seat 2 slides backward, the lever 32 moves the slanted face of the lever 33, pushing the lever 33 upward to prevent the winding roller 22 from rotating. When the support seat 2 is reset forward under the action of the connecting structure 4, the lever 32 contacts the straight face at the rear end of the lever 33, and under the connection of the ratchet 3, it drives the winding roller 22 to rotate, replacing the cleaning cloth 23 at the rear end of the cleaning block 21. By adopting the above transmission method, the cleaning cloth 23 can be wound up to a certain extent after each cleaning, so that each time the camera 11 is clean, the cleaning cloth 23 is in contact with it, increasing the cleaning effect of the camera 11.

[0047] Reference Figure 5 The support plate 13 includes a fixing plate 12 mounted on its upper part. The fixing plate 12 is connected to the camera 11. Positioning rods 5 are fixedly connected to the four corners of the lower end of the fixing plate 12. The four corners of the upper end of the support plate 13 are provided with connecting holes 51, and the positioning rods 5 are inserted into the connecting holes 51. The upper rear side of the inside of the protective box 1 is provided with a retaining groove 14 for locking the fixing plate 12. A buffer spring 52 is installed on the side of the support plate 13 and the fixing plate 12 that are close to each other. The elasticity of the buffer spring 52 is used to buffer the impact force from the vertical direction. The positioning rods 5 are inserted into the connecting holes 51 with a clearance fit.

[0048] The present invention employs the cooperation of a fixed plate 12 and a support plate 13 so that when the camera 11 is inside the protective box 1, the fixed plate 12, under the action of the buffer spring 52, can provide buffering force when it receives an impact, thus preventing the camera 11 from being damaged when it receives an impact.

[0049] Reference Figure 4 , Figure 5 and Figure 7 Inside the protective case 1, a storage groove 6 extending into the retaining groove 14 is provided at the upper rear side. A side-standing U-shaped locking block 61 is slidably connected inside the storage groove 6. Locking grooves 62, which cooperate with the locking block 61, are provided on both sides of the fixing plate 12. The side of the locking block 61 away from the fixing plate 12 is fixedly connected to the storage groove 6 by a spring rod 63. The lower end of the locking block 61 has inclined grooves 64 on both its upper and lower sides for pushing it to slide. The upper end of the locking block 61 extends into the retaining groove 14. When the camera 11 extends out of the protective case 1, the cooperation between the locking block 61 and the locking grooves 62 prevents the camera 11 from shaking, increasing its stability.

[0050] When the camera 11 needs to be retracted into the protective box 1, the lifting mechanism drives the support plate 13 to move downward. At this time, the support plate 13 can cooperate with the inclined groove 64 on the upper side of the lower part of the locking block 61, so that the upper part of the locking block 61 moves out of the locking groove 62 of the fixing plate 12. Then the fixing plate 12 moves into the protective box 1 synchronously with the support plate 13. When the camera 11 needs to be extended, the lifting mechanism drives the support plate 13 to move upward. As the support plate 13 moves upward, the fixing plate 12 abuts against the lower side of the upper part of the locking block 61. Then the support plate 13 moves upward and contacts the inclined groove 64 on the lower side of the lower part of the locking block 61, causing the locking block 61 to retract as a whole. Then the fixing plate 12 contacts the lower side of the stop groove 14. As the support plate 13 separates from the locking block 61, the locking block 61 extends again under the action of the spring rod 63, so that the upper part of the locking block 61 is re-inserted into the locking groove 62.

[0051] When in use, the device controls the support plate 13 to lift the fixed plate 12 and camera 11 upwards via the lifting mechanism. When the fixed plate 12 contacts the lower end of the extended locking block 61, it pushes the locking block 61 through the inclined groove 64. Then, the fixed plate 12 drives the camera 11 to continue to rise. When the fixed plate 12 rises and is blocked by the upper part of the locking block 61, the support plate 13 pushes the locking block 61. The fixed plate 12 continues to slide upwards and is locked inside the stop groove 14. Then, the locking block 61 loses the push of the support plate 13 and is inserted into the locking groove 62 under the push of the spring rod 63, locking the height of the fixed plate 12.

[0052] When storing the camera 11, the lifting mechanism controls the support plate 13 to lower the fixing plate 12 and the camera 11 downwards. The support plate 13 pushes the locking block 61, which is then stored inside the storage slot 6. The fixing plate 12 is unlocked, and the fixing plate 12 and the camera 11 descend. As the support plate 13 descends, the inclined ends of trapezoidal block 1 43 and trapezoidal block 2 431 come into contact with each other, pushing the connecting frame 42 to slide backwards. Under the transmission of the guide groove 451 and guide block 452, the support base 2 moves forward. When the support plate 13 descends, the cleaning block 21 at the rear end of the support base 2 contacts... The slider 471 moves up and down in front of the camera 11 via the drive rail 47. The slider 471 drives the support base 2 to slide up and down, which in turn drives the cleaning block 21 to move up and down. During the up and down movement, the cleaning block 21 moves slightly backward under the guidance of the guide groove 451 and the guide block 452, which increases the pressure when the cleaning block 21 contacts the camera 11, thus wiping away stubborn stains on the outside of the camera 11. When moving downward, the front end of the camera 11 is shifted downward, so that the cleaned dust and debris can fall off easily, avoiding secondary pollution.

[0053] Before cleaning and when the support 2 moves backward, the lever 32 contacts the inclined surface of the lever block 33. At this time, due to the cooperation of the ratchet 3 and the pawl structure 31, the lever 32 pushes the lever block 33, preventing the replacement of the cleaning cloth 23. After cleaning, when the support 2 moves forward, the lever 32 contacts the straight surface of the rear end of the lever block 33. At this time, the ratchet 3 and the pawl structure 31 cannot lock the lever 32. The lever 32 is driven by the lever block 33 to rotate the ratchet 3, which in turn drives the take-up roller 22 to rotate, replacing the cleaning cloth 23 at the front end of the cleaning block 21. This ensures the cleanliness of the cleaning cloth 23, so that each cleaning can achieve good results, reducing wear on the camera 11 and ensuring the imaging quality of the camera 11.
