Description

Technical Field

[0001] The present application relates to the field of drone detection devices, and in particular to a drone zero-value detection device. Background Art

[0002] Zero-value detection of insulator strings is a crucial step in power system maintenance. Its purpose is to promptly detect degraded insulators within the string, thereby preventing electrical accidents caused by insulation failure. The rapid development of the power industry has placed higher demands on insulator string detection technology. Traditional manual inspection methods are inefficient and pose safety risks. Therefore, in recent years, drone technology has been gradually introduced into the field of power equipment inspection, providing a new solution for zero-value detection of insulator strings.

[0003] In existing technologies, zero-value detection of insulator strings is typically achieved through the following methods: The first involves manually climbing to the vicinity of the insulator string and measuring each one individually using handheld testing equipment; the second involves using a long-pole testing device operated from the ground, extending the testing probe toward the insulator string for contact measurement; and the third involves using a drone carrying the testing equipment close to the insulator string and completing the inspection task remotely. While these methods can meet inspection needs to a certain extent, they each have limitations. For example, manual climbing is inefficient, the long-pole testing device has a limited detection range, and traditional drone-mounted testing equipment is often difficult to stably secure to the insulator string, affecting inspection accuracy.

[0004] A common problem with existing drone zero-value detection devices is the inability to reliably secure the detection assembly to the insulator string. This is particularly true in high-altitude environments, where wind and other external factors can easily cause the detection assembly to shift or fall off, leading to unstable detection processes and inaccurate test results. Therefore, designing a drone zero-value detection device that improves overall device stability during testing has become a pressing technical challenge. Summary of the Invention

[0005] In order to improve the overall equipment stability during detection, the present application provides a drone zero value detection device.

[0006] The present application provides a drone zero value detection device that adopts the following technical solution: A zero-value detection device for a drone, comprising: A drone having a mounting portion; a crossbar connected to the mounting portion, the crossbar being parallel to the first direction; A detection component is connected to the crossbar; a first drive assembly connected to the crossbar; and An installation component, the installation component comprising: a bidirectional screw rod, the bidirectional screw rod being parallel to the first direction and capable of rotating about its own central axis; the bidirectional screw rod being connected to the first drive assembly so as to be driven by the first drive assembly to rotate the bidirectional screw rod about its own central axis; and An abutment plate is slidably connected to the cross bar along a first direction, and each corresponding threaded connection of the two threaded segments of the bidirectional screw is connected to an abutment plate; the abutment plate has an abutment end, and in a second direction, the abutment end of the abutment plate is located on the side of the bidirectional screw away from the cross bar.

[0007] By adopting the above technical solution, the drone zero-value detection device can achieve stable fixation and accurate detection of insulator strings. The specific effects are as follows: the drone is connected to the crossbar through the mounting portion, allowing the entire device to be flexibly moved to the target position in the air; when the drone drives the abutment plate to move to the gap between the two insulating porcelain bottles, the detection component installed on the crossbar can perform zero-value detection on the insulator string; the first drive component drives the bidirectional screw to rotate, thereby driving the two abutment plates to move toward or away from each other along the crossbar, so that the abutment plates can firmly clamp the adjacent insulating porcelain bottles of the insulator string, ensuring the stability of the device during the detection process.

[0008] Optionally, two of the installation components are connected to the crossbar, and the two installation components are spaced apart in the first direction.

[0009] By adopting this technical solution, compared to a single mounting assembly, two mounting assemblies can better distribute the force, improving the stability of the entire zero-value detection device during operation, thereby ensuring the accuracy of the detection results. At the same time, this structural design also facilitates the adjustment of the overall balance of the device.

[0010] Optionally, the first driving component includes: A first double-headed motor, wherein the first double-headed motor is fixedly connected to the cross bar, and the two output shafts of the first double-headed motor are respectively connected to one of the bidirectional screws.

[0011] By adopting this technical solution, the two output shafts of the first double-ended motor are connected to the two bidirectional screws, allowing the first double-ended motor to simultaneously drive the two bidirectional screws to rotate. The rotation of the bidirectional screws changes the spacing between the two abutment plates. This design not only simplifies the drive structure but also ensures the synchronization of the two bidirectional screws, making the adjustment of the abutment plate position more precise and efficient.

[0012] Optionally, the first driving component further includes: The telescopic rod has two output shafts of the first double-headed motor each connected to a corresponding telescopic rod, and the other end of the telescopic rod is fixedly connected to the bidirectional screw; the telescopic direction of the telescopic rod is parallel to the first direction.

[0013] By adopting this technical solution, the telescopic rod allows the bidirectional screw to be adjusted along the first direction. In practice, this design allows the mounting assembly to be flexibly adjusted based on the specific position of the insulator string, thereby improving the adaptability of the device. Furthermore, because the telescopic rod's extension direction is parallel to the first direction, the bidirectional screw is prevented from deflecting during movement, further ensuring the stability and detection accuracy of the device.

[0014] Optionally, a second drive assembly is further included, wherein the second drive assembly includes: a second double-headed motor, the second double-headed motor being fixedly connected to the crossbar; a one-way screw rod, wherein the one-way screw rod is parallel to the first direction, and the two output shafts of the second double-headed motor are respectively connected to one of the one-way screw rods to drive the one-way screw rod to rotate around the central axis of the one-way screw rod; and A connecting bar is provided at each end of the second double-headed motor; one end of the connecting bar is threadedly connected to the one-way screw, and the other end is fixedly connected to the end of the telescopic rod away from the second double-headed motor.

[0015] By adopting this technical solution, the second double-headed motor is fixed to the crossbar, and its output shaft is connected to a one-way screw. The rotation of the one-way screw drives the connecting bar in the first direction. The connecting bar is connected to the telescopic rod, thereby adjusting the position of the mounting assembly. This design significantly improves the adaptability of the device, enabling stable installation on insulator strings of different specifications, while facilitating precise alignment and improving detection efficiency and accuracy.

[0016] Optionally, the crossbar includes a plurality of branch rods, and the plurality of branch rods are arranged in sequence along the first direction; At one end of the two branch rods close to each other, a slot is provided at the end of one of the branch rods, and an insertion rod is protruded from the end of the other branch rod, and the insertion rod is adapted to be inserted into the slot.

[0017] By adopting this technical solution, the crossbar is composed of multiple sub-bars, which are detachably connected through slots and plug-in rods. This design allows the crossbar length to be flexibly adjusted according to actual needs, facilitating use in different scenarios. The segmented structure also facilitates transportation and storage, reducing space requirements.

[0018] Optionally, the installation component further includes: A rotating seat is slidably connected to the cross bar along a first direction, the bidirectional screw is passed through the rotating seat along the first direction, and the rotating seat is located in the middle of the bidirectional screw, and a bearing is provided between the bidirectional screw and the rotating seat.

[0019] By adopting this technical solution, the provision of a rotating seat enables the bidirectional screw to rotate stably on the rotating seat, thereby ensuring that the abutment plate can move smoothly in the first direction during the bidirectional screw's rotation. Furthermore, the sliding connection between the rotating seat and the crossbar, combined with the configuration of the first perforation, allows the entire mounting assembly to be flexibly adjusted on the crossbar to accommodate insulator strings of varying specifications. The addition of bearings further reduces friction between the bidirectional screw and the rotating seat, improving the smoothness of rotation and thus enhancing the overall operational performance and stability of the device.

[0020] Optionally, in the installation assembly, a corresponding embedding groove is formed on each side of the two abutment plates that are away from each other, and the embedding groove is adapted to fit the insulating porcelain bottle.

[0021] By adopting the above technical solution, the setting of the embedding groove enables the abutment plate to better fit the shape of the insulating porcelain bottle when in contact with the insulating porcelain bottle, thereby improving the fixing effect of the abutment plate on the insulating porcelain bottle.

[0022] Optionally, a flexible anti-slip pad is provided on the inner wall of the embedding groove.

[0023] By adopting the above technical solution, the setting of the flexible anti-slip pad can increase the friction between the abutment plate and the insulating porcelain bottle, effectively reduce the slipping phenomenon between the two, thereby improving the fixation of the abutment plate to the insulating porcelain bottle, and ensuring the stability and reliability of the zero value detection device during operation.

[0024] Optionally, a first through hole for accommodating the cross bar is opened on the rotating seat along the first direction, and the rotating seat is provided with a plurality of balls on the inner wall of the first through hole. The balls are embedded in the rotating seat and can rotate freely along the rotating seat.

[0025] By adopting the above technical solution, when the rotating seat slides on the cross bar, the ball bearings can significantly reduce the friction between the rotating seat and the cross bar, thereby making the movement of the rotating seat smoother.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The cooperation between the bidirectional screw and the abutment plate can stably fix the detection device on the insulator string, effectively preventing displacement or falling off caused by external factors such as wind, and significantly improving the stability of the detection process; 2. The first drive assembly drives the bidirectional screw to rotate, which can accurately adjust the distance between the two abutment plates to accommodate the gaps between insulating porcelain bottles of different sizes, thereby enhancing the applicability of the device. 3. Two mounting components are set on the crossbar, and the distance between them is adjusted by the second drive component, which further improves the balance and stability of the device on the insulator string and ensures detection accuracy.

[0029] The following is combined with Figure 1-3 For the convenience of description, this application introduces directional terms such as the first direction and the second direction. The directional terms used, such as "first direction, second direction", can be specifically shown in the figure, where X represents the first direction and Y represents the second direction, and the first direction and the second direction are perpendicular to each other.

[0030] The embodiment of the present application discloses a drone zero value detection device. Figure 1The drone zero value detection device includes a drone 1, a crossbar 2, a first drive assembly 3 and a mounting assembly 4; the drone 1 has a mounting portion 11, and the mounting portion 11 of the drone 1 is a rod-shaped structure extending to the bottom of the drone 1; the crossbar 2 is parallel to the first direction, and a vertical rod 21 is fixedly connected to the crossbar 2, the vertical rod 21 and the mounting portion 11 are both parallel to the second direction, and the vertical rod 21 is connected to the mounting portion 11 through a flange; the mounting assembly 4 and the first drive assembly 3 are both connected to the crossbar 2.

[0031] Reference Figure 1 A detection component 5 is provided at each end of the cross bar 2, and the detection component 5 includes an electric push rod 51, a resistance detection probe 52 and a detection controller 53; the driving direction of the electric push rod 51 is parallel to the first direction, one end of the electric push rod 51 is fixedly connected to the mounting frame, and the other end is fixedly connected to the resistance detection probe 52; in the second direction, the resistance detection probe 52 is located at the end of the cross bar 2 away from the drone 1; the detection controller 53 is fixedly connected to the cross bar 2, and the resistance detection probe 52 is communicated with the detection controller 53, and the resistance detection probe 52 is used to detect the insulator string 7.

[0032] Reference Figure 1 and Figure 2 The mounting assembly 4 includes a bidirectional screw 41, a rotating seat 42 and an abutment plate 43. In the second direction, the drone 1, the cross bar 2 and the bidirectional screw 41 are distributed in sequence; the bidirectional screw 41 is parallel to the first direction, and the bidirectional screw 41 can rotate around the central axis of the bidirectional screw 41 itself under the drive of the first driving assembly 3; the bidirectional screw 41 is slidably connected to the cross bar 2 along the first direction through the rotating seat 42. In order to connect the bidirectional screw 41 with the cross bar 2, a first through-hole 421 for accommodating the cross bar 2 is opened on the rotating seat 42 along the first direction. The rotating seat 42 is provided with a plurality of balls 422 on the inner wall of the first through-hole 421. The balls 422 are embedded in the rotating seat 42 and can rotate freely along the rotating seat 42, so that the movement of the rotating seat 42 along the cross bar 2 is smoother; The bidirectional screw 41 is inserted into the rotating seat 42 along a first direction, and the rotating seat 42 is located in the middle of the bidirectional screw 41. A bearing 44 is sandwiched between the bidirectional screw 41 and the rotating seat 42, so that the bidirectional screw 41 can rotate on the rotating seat 42 along the central axis of the bidirectional screw 41 via the bearing 44. A second through-hole 431 is formed at one end of the abutment plate 43 along the first direction, and the cross bar 2 is passed through the second through-hole 431. Guided by the wall of the second through-hole 431, the abutment plate 43 can slide on the cross bar 2 along the first direction. The two threaded segments of the bidirectional screw 41 are each threadedly connected to an abutment plate 43. The abutment plate 43 has an abutment end 432. In the second direction, the abutment end 432 of the abutment plate 43 is located on the side of the bidirectional screw 41 away from the cross bar 2. Under the configuration of the first through-hole 421 and the second through-hole 431, the entire mounting assembly 4 moves along the first direction on the crossbar 2, so as to facilitate moving the mounting assembly 4 to different positions of the insulator string 7; in the process of rotating the bidirectional screw 41, the two abutment plates 43 will move in opposite directions; during operation, the abutment ends 432 of the two abutment plates 43 are inserted between two adjacent insulating porcelain bottles 72, and when the two move in directions away from each other, the two adjacent insulating porcelain bottles 72 will be pressed tightly by the two abutment plates 43, so that the entire zero-value detection device can be fixed on the insulator string 7; when it needs to be removed, it is only necessary to move the two abutment plates 43 toward the side close to each other, and when the abutment plates 43 and the insulating porcelain bottles 72 are separated, the entire zero-value detection assembly 5 can be removed from the insulator string 7; In order to improve the firmness of the abutment between the abutment plate 43 and the insulating porcelain bottle 72, in the mounting assembly 4, the two abutment plates 43 are each provided with a corresponding embedding groove 433 on one side away from each other, and the embedding groove 433 is adapted to the insulating porcelain bottle 72; furthermore, a flexible anti-skid pad 434 is provided on the inner wall of the embedding groove 433. The flexible anti-skid pad 434 is made of flexible rubber. When the flexible anti-skid pad 434 contacts the insulating porcelain bottle 72, it can reduce slipping. In order to further improve the stability of the abutment plate 43, in some embodiments of the present application, the abutment end 432 of the abutment plate 43 is provided with an insertion slot 435 for inserting the straight rod 71 of the insulator string 7. When the abutment plate 43 is moved to allow the straight rod 71 of the insulator string 7 to be inserted into the insertion slot 435, the stability of the entire zero value detection assembly 5 on the insulator string 7 can be improved; when the abutment plate 43 is overlapped with the insulator string 7 through the slot wall of the insertion slot 435, the resistance detection probe 52 contacts the insulator string 7.

[0033] Reference Figure 2 and Figure 3 In some embodiments of the present application, two mounting assemblies 4 are connected to the crossbar 2, and the two mounting assemblies 4 are spaced apart in the first direction. With the cooperation of the two mounting assemblies 4 and the insulator string 7, the entire zero-value detection assembly 5 can stand more stably on the insulator string 7; and in the first direction, the drone 1 and the vertical pole 21 are located in the middle of the two mounting assemblies 4, so that the entire zero-value detection assembly 5 can maintain balance.

[0034] The first driving assembly 3 is used to drive the bidirectional screws 41 in the two mounting assemblies 4 to rotate around the central axis of the bidirectional screws 41 themselves; the first driving assembly 3 includes a first double-headed motor 31 and a telescopic rod 32, the first double-headed motor 31 is fixedly connected to the cross bar 2, and the two output shafts of the first double-headed motor 31 are coaxially arranged with one bidirectional screw 41 respectively; the telescopic rod 32 is connected between the first double-headed motor 31 and the bidirectional screw 41, and the telescopic direction of the telescopic rod 32 is parallel to the first direction, the two output shafts of the first double-headed motor 31 are fixedly connected with one telescopic rod 32 respectively, and the other end of the telescopic rod 32 is fixedly connected to the screw; The telescopic rod 32 includes a fixed rod 321 and a sliding rod. The fixed rod 321 is coaxially fixedly connected to the output shaft of the second double-headed motor 61, and the sliding rod is coaxially fixedly connected to the bidirectional screw 41 of the rotating rod. One end of the movable rod 322 of the second double-headed motor 61 is provided with a guide groove 3221 along the first direction. The fixed rod 321 is inserted into the guide groove 3221. Under the guidance of the groove wall of the guide groove 3221, the sliding rod can slide along the first direction. The cross-sections of the guide groove 3221 and the sliding rod along the direction perpendicular to the first direction are both rectangular, so as to ensure that the sliding rod and the fixed rod 321 can rotate synchronously. When the first double-headed motor 31 drives the telescopic rod 32 to rotate, it can drive the bidirectional screw 41 to rotate to change the distance between the two abutment plates 43; if the position of the entire installation component 4 needs to be adjusted, the position of the entire installation component 4 can be changed by simply changing the length of the telescopic rod 32.

[0035] Reference Figure 3 In order to adjust the overall position of the mounting assembly 4 on the cross bar 2, some embodiments of the present application further include a second drive assembly 6, which includes a second double-headed motor 61, a one-way screw 62 and a connecting bar 63; in the second direction, the second double-headed motor 61 and the one-way screw 62 are both located on the side of the cross bar 2 close to the drone 1, and the second double-headed motor 61 is fixedly connected to the cross bar 2; the end away from the drone 1 is fixedly connected to the second double-headed motor 61; the one-way screw 62 is parallel to the first direction, and the two output shafts of the second double-headed motor 61 are coaxially fixedly connected to a one-way screw 62 to drive the one-way screw 62 to rotate around the central axis of the one-way screw 62 itself; in the first direction, a connecting bar 63 is distributed at each end of the second double-headed motor 61; one end of the connecting bar 63 is threadedly connected to the one-way screw 62, and the other end is fixedly connected to the end of the telescopic rod 32 away from the second double-headed motor 61; an avoidance hole 631 for the cross bar 2 to pass through is opened on the connecting bar 63 along the first direction; The connecting bar 63 in the present disclosure is fixedly connected to the sliding rod in the telescopic rod 32. Since the fixed rod 321 has a guiding effect on the sliding rod, the second double-headed motor 61 can drive the connecting bar 63 to move along the first direction when driving the one-way screw 62 to rotate.

[0036] Reference Figure 4 In some embodiments of the present application, the cross bar 2 includes a plurality of branch rods 22, the branch rods 22 are parallel to the first direction, and the plurality of branch rods 22 are arranged in sequence along the first direction; at one end of the two branch rods 22 close to each other, a slot 221 is provided at the end of one of the branch rods 22, and an insertion rod 222 is protruded at the end of the other branch rod 22, and the insertion rod 222 is adapted to be inserted into the slot 221. In order to improve the firmness between the two adjacent branch rods 22, the connection between the two adjacent branch rods 22 is fixedly connected by a countersunk screw 223.

[0037] The implementation principle of the zero-value detection device of the drone 1 according to the embodiment of the present application is as follows: during operation, the drone 1 drives the entire zero-value detection assembly 5 to move above the insulator string 7, then moves the zero-value detection assembly 5 so that the straight rod 71 is located in the insertion slot 435, and then the first double-headed motor 31 drives the bidirectional screw 41 to rotate so that the abutment plate 43 presses against the insulating porcelain bottle 72, and then the zero-value detection can be performed; When disassembly is required, it is only necessary to drive the bidirectional screw 41 to rotate so as to separate the two abutting plates 43 from the insulating porcelain bottle 72 , and the drone 1 can then drive the entire zero-value detection assembly 5 to separate.

[0038] If the distance between two adjacent mounting assemblies 4 needs to be adjusted, the first double-headed motor 31 only needs to drive the one-way screw 62 to rotate to drive the telescopic rod 32 to extend and retract, thereby adjusting the two mounting assemblies 4 to the desired position.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
