[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-17The embodiment of the present invention provides a line detection device that is easy to install, including a detection box 1, a detection camera 2 arranged on the detection box 1 for detecting the line, a hanger 7 arranged on the detection box 1 and cooperating with the drone, and at least one suspension mechanism, wherein it should be noted that the detection box 1 and the detection camera 2 are prior arts, and the detection function of the detection box 1 and the visual detection function of the detection camera 2 are very mature, and are not described in detail here; the suspension mechanism includes two symmetrically arranged suspension units 3, each suspension unit 3 includes a rotating arm 301, a guide arm 302 and a locking member 303; the rotating arm 301 is rotatably connected to the detection box 1, and the rotating The arm 301 is rotatably connected with a suspension wheel 304; the guide arm 302 includes a vertical section 3021 and an inclined section 3022, the vertical section 3021 is fixedly connected to the detection box 1, and a limiting cavity 3023 is provided on the vertical section 3021, the vertical section 3021 is fixedly connected to the oblique lower end of the inclined section 3022, and a sliding part 4 is vertically slidably connected in the limiting cavity 3023; during the rising process of the guide arm 302, the sliding part 4 is driven to abut against the line, the sliding part 4 slides down relative to the guide arm 302 and drives the rotating arm 301 to rotate to the suspension wheel 304 through the transmission component 5 to be suspended and installed on the line, and the rotating arm 301 is locked relative to the detection box 1 through the locking member 303. It should be noted that the oblique upper end of each inclined section 3022 extends out of the peripheral side of the detection box 1. Among them, each rotating arm 301 is provided with a driving motor, and the rotating output end of the driving motor is transmission-connected with the corresponding suspension wheel 304, so as to drive the suspension installed on each suspension wheel 304 to move on the line, so as to facilitate the detection box 1 to detect the line; at the same time, each suspension wheel 304 can be a rubber wheel, which has a certain elasticity and shock absorption ability, which is conducive to the suspension wheel 304 to move on the line. Among them, it should be further explained that this device can be lifted by a drone. In the preferred state, the sling 7 is a connecting frame fixedly connected to the detection upward hook, and the hook is located on the center of gravity line of the detection box 1, so that the hook on the drone can cooperate with the hook to drive the detection box 1 to maintain a vertical state and hang on the line. As a preferred embodiment of the present invention, Figure 3 As shown, there are preferably two suspension mechanisms, which are arranged on the detection box 1 in the front and back of the detection box 1 along the running direction of the line, thereby increasing the stability of the detection box 1 when it is running on the line.

[0036] Specifically, while the detection box 1 is moving upward vertically, the inclined sections 3022 of the guide arms 302 of the two suspension units 3 will first contact the line, and then the detection box 1 in the suspended state will continue to move upward so that the line can quickly slide into the limiting cavity 3023 of the vertical section 3021 under the guidance of the inclined sections 3022 of the guide arms 302. The whole process not only accelerates the positioning and installation of the detection box 1 on the line, but also prevents the suspension wheel 304 on the line from displacement deviation during the suspension installation process, thereby reducing the risk of the suspension wheel 304 falling off when walking on the line later; and even in windy weather, it can solve the problem that the detection box 1 in a shaking state cannot be quickly positioned The problem of installing the detection box 1 on the line; when the line is located in the limiting cavity 3023, the detection box 1 needs to continue to move upward, which will drive the limiting abutment sliding part 4 to make the sliding part 4 slide down relative to the vertical section 3021, and in the process of sliding down, the transmission component 5 drives each suspension wheel 304 to rotate relative to the detection box 1, thereby driving the suspension wheel 304 to be suspended and installed on the line, and after the suspension installation is completed, the locking member 303 is used to lock the rotating arm 301 to limit the rotation of the rotating arm 301 relative to the detection box 1; the entire installation process does not require the staff to climb to the top of the tower or the appropriate position near the line to install the detection box 1, which greatly enhances the safety of the staff's working environment and avoids personal injuries caused by falling and electric shock. At the same time, the installation process can drive the rotating arm 301 to rotate without the help of a cylinder or a motor so that each suspension wheel 304 is suspended and installed on the line, so that the effect of reducing the entire device can be achieved, and the weight of the entire device is reduced to a certain extent, so that the detection box 1 can reduce the burden of the entire device on the line during the detection process.

[0037] It should also be noted that the line inlet of the limiting cavity 3023 for guiding the line into can be arranged at an angle, and the inclination direction of the line inlet is consistent with the inclination direction of the inclined section 3022. Therefore, when the suspension wheel 304 is suspended and installed on the line, although it is misaligned with the line inlet of the limiting cavity 3023, it still has the effect of sealing the line inlet of the limiting cavity 3023, which can prevent the suspension wheel 304 suspended on the line from detaching from the line during subsequent walking and encountering strong winds and other weather conditions, thereby avoiding the risk of the detection box 1 falling.

[0038] Each sliding part 4 includes: a sleeve arm 401, a first spring 402, a hollow column 403, a slider 406, an inner rod 407, a first elastic member 409 and a second elastic member 410. The sleeve arm 401 is vertically slidably connected to the vertical section 3021; ​​the first spring 402 is sleeved on the sleeve arm 401, and one end is fixedly connected to the sleeve arm 401, and the other end is fixedly connected to the vertical section 3021; ​​the hollow column 403 is rotatably connected to the sleeve arm 401, and a spiral slide groove 404 is provided on the peripheral side surface of the hollow column 403, and a guide groove 405 is provided on the inner wall of the hollow column 403, and the guide groove 405 includes The arc-shaped notch 4051 and the vertical groove 4052 are connected, and the depth of the vertical groove 4052 gradually becomes shallower from top to bottom; the slider 406 is located in the spiral slide groove 404 and is fixedly connected to the inner wall of the limiting cavity 3023; the inner rod 407 is vertically slidably connected in the sleeve arm 401, and the inner rod 407 is radially slidably connected with a protrusion 408 located in the guide groove 405; the process of the first elastic member 409 restoring the elastic deformation drives the inner rod 407 to move upward relative to the sleeve arm 401; the process of the second elastic member 410 restoring the elastic deformation drives the protrusion 408 to slide relative to the inner rod 407 to be inserted into the arc-shaped notch 4051. It should be noted that a first limiting groove is provided on the inner wall of the limiting cavity 3023, and a first limiting block located in the first limiting groove is fixedly connected to the sleeve arm 401. When the sliding part 4 slides along the limiting cavity 3023, the sleeve arm 401 is in a state of sliding along the limiting cavity 3023, and with the cooperation of the first limiting block and the second limiting groove, the sleeve arm 401 slides in a linear motion relative to the vertical section 3021, which is beneficial for the subsequent rotation of the rotating arm 301 through the transmission assembly 5. It should be further explained that the number of turns of the spiral groove 404 on the hollow column 403 is less than one turn, and the annular groove provided on the inner wall of the hollow column 403 is consistent with the number of turns of the spiral groove 404. At this point, when the hollow column 403 rotates relative to the sleeve arm 401 through the cooperation of the slider 406 and the spiral groove 404, the protrusion 408 provided on the inner rod 407 will slide from the closed end of the annular groove to the junction of the annular groove and the vertical groove 4052. At this time, the locking member 303 provided can lock the corresponding rotating arm 301 with the detection box 1. The inner rod 407 is located at the junction of the annular notch and the vertical groove 4052, and the inner rod 407 can slide vertically relative to the sleeve arm 401; and the protrusion 408 located in the arc-shaped notch 4051 can limit the vertical sliding of the inner rod 407 relative to the sleeve arm 401, so that the locking member 303 will not cause relative sliding between the inner rod 407 and the sleeve arm 401 before the locking effect is achieved, which is conducive to the subsequent driving of the suspension wheel 304 to be suspended and installed on the line through the transmission assembly 5.It should also be noted that a second limit groove is provided in the sleeve arm 401, and a second limit block located in the second limit groove is fixedly connected to the inner rod 407, so that the inner rod 407 can only slide along the sleeve arm 401 relative to the vertical straight line. It should be further noted that when the drone drives the detection box 1 to move upward so that the sliding part 4 slides relative to the vertical section 3021 to a set threshold, the locking member 303 is used to lock the rotating arm 301 relative to the detection box 1, and the drone will be in a high-altitude hovering state (or a displacement sensor is provided on the sleeve arm 401 in the sliding part 4, and when the sleeve arm 401 slides a certain distance until the locking member 303 is in a locked state, the displacement sensor feeds back to the drone so that the drone is in a high-altitude hovering state).

[0039] Each transmission assembly 5 includes: a rack 501, a shaft 502 and a gear 503, wherein the rack 501 is fixedly connected to the sleeve arm 401; the shaft 502 is rotatably connected to the detection box 1, and the shaft 502 is fixedly connected to the corresponding rotating arm 301; the rack 501 is fixedly connected to the shaft 502 and meshes with the rack 501; during the sliding of the sleeve arm 401 relative to the guide arm 302, the rack 501 drives the gear 503 to rotate so that the shaft 502 rotates relative to the detection box 1. It should be noted that the length direction of the rack 501 is the direction in which the sleeve arm 401 slides linearly relative to the vertical section 3021. It should be further noted that the rack 501 and the gear 503 are always kept in a meshing state, so when each suspension wheel 304 is suspended and installed on the line, the gear 503 and the rack 501 in the meshing state allow the corresponding suspension wheel 304 to be stably suspended and installed on the line, which is conducive to the subsequent movement of each suspension wheel 304 on the line.

[0040] Among them, each locking member 303 includes: a first wedge block 3031, a second wedge block 3032, a through groove 3033 and a third elastic member 3034, the first wedge block 3031 is fixedly connected to the inner wall of the corresponding limiting cavity 3023; the second wedge block 3032 is radially slidably connected to the inner rod 407; the through groove 3033 is opened on the sleeve arm 401, and is used for the second wedge block 3032 to pass through the through groove 3033 of the sleeve arm 401, and the through groove 3033 has a guide surface that abuts and cooperates with the inclined surface of the second wedge block 3032; the process of the third elastic member 3034 restoring elastic deformation drives the second wedge block 3032 to slide radially so that the second wedge block 3032 extends out of the through groove 3033. When the sleeve arm 401 has finished sliding down relative to the vertical section 3021, the first wedge block 3031 and the second wedge block 3032 cooperate with each other to achieve the effect of locking the sleeve arm 401, and at this time, the sleeve arm 401 slides to the lowest end in the limiting cavity 3023, so that the sleeve arm 401 and the vertical section 3021 are in a relatively locked state, and through the meshing cooperation between the gear 503 and the rack 501, the rotating arm 301 can be locked relative to the detection box 1, so as to facilitate the suspension wheel 304 to be stably suspended and installed on the suspension wheel 304. It should be noted that the third elastic member 3034 includes a third spring radially slidably connected to the slide rod and sleeved on the slide rod, and one end of the third spring is fixedly connected to the second wedge block 3032, and the other end is fixedly connected to the outer wall of the inner rod 407. It should be further explained that the opening area of ​​both sides of the through-hole 3033 gradually increases from the outside to the inside to prevent the second wedge block 3032 from radially sliding out of the through-hole 3033 and extending into the sleeve arm 401 as a whole, and the guide surface of the through-hole 3033 is arranged in an inclined manner, and the inclination of the guide surface is consistent with the inclination of the inclined surface of the second wedge block 3032, which is conducive to the subsequent second wedge block 3032 to slide radially close to the inner rod 407 through the cooperation of the guide surface and completely disengage from the through-hole 3033 to achieve the effect of unlocking the sleeve arm 401. It should be further explained that the drone drives the detection box 1 to move upward to slide the inner rod 407 to the set threshold so that the locking member 303 is in the unlocked state, and the drone is in a hovering state.

[0041] Each first elastic member 409 is a spring telescopic rod, and one end of the spring telescopic rod is fixedly connected to the corresponding inner rod 407, and the other end is fixedly connected to the corresponding sleeve arm 401. It should be noted that the process of the spring telescopic rod restoring elastic deformation is used to drive the inner rod 407 to slide up relative to the sleeve arm 401. It should be further noted that the elastic force of the first spring 402 to restore the elastic deformation is preferably much greater than the elastic force of the first elastic member 409 to restore the elastic deformation. Thus, during the process of the inner rod 407 sliding up relative to the sleeve arm 401, the first spring 402 can overcome the elastic force of the first elastic member 409 to restore the elastic deformation so that the inner rod 407 can maintain a state of sliding up relative to the sleeve arm 401.

[0042] Each second elastic member 410 includes a storage cavity and a second spring, the storage cavity is provided on the corresponding inner rod 407, the second spring is located in the storage cavity, and one end of the second spring is fixedly connected to the protrusion 408, and the other end is fixedly connected to the inner wall of the storage cavity. It should be noted that when the inner rod 407 receives the elastic force of the first elastic member 409 to slide the inner rod 407 relative to the sleeve arm 401 to the maximum distance, the second spring restores the elastic deformation process at this time so that the protrusion 408 is inserted into the arc-shaped slot 4051, and is inserted into the closed end of the arc-shaped slot 4051.

[0043] The top of each inner rod 407 is rotatably connected with an auxiliary wheel 6. It should be noted that each auxiliary wheel 6 plays an auxiliary role when each suspension wheel 304 walks on the line, reducing the wear between the inner rod 407 and the line, thereby effectively protecting the line from damage.

[0044] Specifically, the installation process is the process of driving the sliding part 4 to slide vertically relative to the vertical section 3021, that is, the drone needs to drive the detection box 1 to move up so that the line in the limiting cavity 3023 abuts the auxiliary wheel 6 to drive the sleeve arm 401, the hollow column 403 and the inner rod 407 as a whole to slide linearly relative to the vertical section 3021 in the limiting cavity 3023, and during the vertical sliding of the sliding part 4, the hollow column 403 slides from the lowest end of the spiral groove 404 to the highest end of the spiral groove 404 through the provided slider 406 so that The hollow column 403 rotates relative to the sleeve arm 401, and during the rotation of the hollow column 403, the protrusion 408 provided on the inner rod 407 will always be located in the arc-shaped notch 4051 to prevent the inner rod 407 from sliding relative to the sleeve arm 401, that is, the sleeve arm 401, the hollow column 403 and the inner rod 407, which are completed as a whole, can slide down relative to the guide arm 302; during the rotation of the hollow column 403, the protrusion 408 will slide from the closed end of the arc-shaped notch 4051 to the connection between the arc-shaped notch 4051 and the vertical groove 4052 due to the rotation of the hollow column 403 When the inner rod 407 is in a state of being able to slide vertically relative to the sleeve arm 401, the inclined surface of the second wedge block 3032 sliding down linearly with the sleeve arm 401 abuts against the inclined surface of the first wedge block 3031 to make the second wedge block 3032 slide radially until the inclined surface of the second wedge block 3032 is separated from the inclined surface of the first wedge block 3031, and then the second wedge block 3032 is driven to engage with the first wedge block 3031 during the process of the third elastic member 3034 restoring elastic deformation to achieve the effect of locking the sleeve arm 401; wherein, the sleeve arm 401 The process of the relative vertical section 3021 sliding down will drive the rack 501 to synchronously slide down to cooperate with the gear 503, thereby driving the shaft 502 connected to the detection box 1 to rotate so that the suspension wheel 304 is suspended and installed on the line, and at this time, the sleeve arm 401 is always in a locked state, and the gear 503 and the rack 501 that remain in a meshing state will limit the rotation of the rotating arm 301, that is, the two suspension wheels 304 of the suspension mechanism are synchronously suspended and installed on the line, and the stability of the subsequent suspension wheel 304 when walking on the line is guaranteed.

[0045] Specifically, the whole device is disassembled from the line by driving the detection box 1 to move up relative to the line by the drone, that is, the sleeve arms 401 locked on the vertical section 3021 move up synchronously, and at this time, the line in the cavity abuts the auxiliary wheel 6 so that the inner rod 407 can be retracted into the sleeve arm 401, that is, the inner rod 407 is in a downward sliding state relative to the sleeve arm 401, that is, the protrusion 408 arranged on the inner rod 407 can slide in the vertical groove 4052, and the sliding process will drive the protrusion 408 to compress the second spring to be stored in the storage cavity until it is out of the vertical groove 4052, and at the same time, the inner rod 407 will drive the second wedge block 3032 The relative sleeve arm 401 moves downward, and the inclined guide surface in the through-mouth groove 3033 abuts and cooperates with the inclined surface of the second wedge block 3032 to make the second wedge block 3032 slide radially until it is completely out of the through-mouth groove 3033. After that, the drone needs to be in a state of hovering and stopping. At this time, the process of the first spring 402 restoring elastic deformation drives the sleeve arm 401 to slide up relative to the vertical section 3021. This process can drive the gear 503 to move upward and drive the rack 501 to drive the rotating arm 301 fixedly connected to the shaft rod 502 to rotate relative to the detection box 1 to make the suspension wheel 304 out of the line, and this process makes the through-mouth set on the sleeve arm 401 The groove 3033 will slide up and pass over and away from the first wedge block 3031, and the slider 406 set in the upward sliding process will slide from the highest end of the spiral groove 404 to the lowest end of the spiral groove 404 to make the hollow column 403 rotate relative to the sleeve arm 401 and restore to the initial state. When the suspension wheel 304 is separated from the line, the drone drives the detection box 1 to move downward. At this time, the inner rod 407 is driven by the elastic force of the first elastic member 409 to restore the elastic deformation so that the inner rod 407 moves upward relative to the sleeve arm 401 until the line is separated from the limiting cavity 3023; wherein, after the first elastic member 409 is completely restored to its deformation, the second wedge block 3032 is in the first The three elastic members 3034 restore the elastic deformation under the elastic force so that the second wedge block 3032 is inserted into the through-mouth groove 3033 and extends a part of it, which is conducive to the next cooperation with the first wedge block 3031; wherein, since the hollow column 403 has been restored to its initial state, and the inner rod 407 has been in a vertical linear sliding process, when the first elastic member 409 fully restores the deformation, the protrusion 408 arranged on the inner rod 407 will be driven by the elastic force of the elastic deformation restored by the second elastic member 410 to slide radially so as to be inserted into the closed end of the annular groove, thereby facilitating the next installation operation.

[0046] In summary, the entire installation and disassembly process only requires remote control with the help of a drone, and there is no need to manually climb to the top of the pole tower or a suitable position near the line to perform installation or disassembly operations, which greatly reduces various safety risks such as falling and electric shock. At the same time, the installation and unlocking operations are simple and convenient, and there is no need to use driving devices such as cylinders or motors, which reduces the weight of the entire device to a certain extent, so that the detection box 1 reduces the burden of the entire device carried by the line during the detection process.
