Description

Technical Field

[0001] This application relates to the field of inspection equipment technology, and in particular to an inspection device. Background Technology

[0002] With the continuous development of power technology, inspection equipment is installed on high-voltage transmission lines to monitor the transmission lines and the surrounding environment.

[0003] In related technologies, the inspection equipment includes a first housing and a second housing, and a locking component is provided between the first housing and the second housing to lock the first housing and the second housing together, so that the first housing and the second housing are stably fastened to the power transmission line.

[0004] However, the inspection equipment is mounted on the power transmission line, and the locking components are difficult to open, which reduces the efficiency of disassembling the inspection equipment. Utility Model Content

[0005] This application provides an inspection device that solves the technical problem that the difficulty in opening the locking components leads to a decrease in the disassembly efficiency of the inspection device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides an inspection device, including:

[0008] A first housing and a second housing are arranged opposite each other and their first ends are rotatably connected to each other. Their second ends move toward each other or away from each other under the action of a force.

[0009] The locking assembly includes a first locking member, a second locking member, a transmission mechanism, a connecting rod, and a lifting member. The first locking member is fixed to the first housing, the second locking member is movably disposed on the second housing, and the second housing has a vertically extending sliding hole, through which the connecting rod passes. The transmission mechanism is movably disposed on the second housing, and its two ends are respectively pivotally connected between the bottom ends of the second locking member and the connecting rod. The lifting member is connected to the top end of the connecting rod.

[0010] When the first housing and the second housing are engaged, the first locking member and the second locking member are arranged horizontally and locked together. When an upward lifting force is applied to the lifting member, the lifting member drives the connecting rod to move upward, so that the connecting rod is carried by the transmission mechanism to the second locking member to move away from the first locking member, until the first locking member and the second locking member unlock each other.

[0011] As an optional implementation, the locking assembly further includes a bearing located between the outer peripheral wall of the connecting rod and the inner peripheral wall of the sliding hole.

[0012] As an optional implementation, a rolling structure is provided between the outer peripheral wall of the connecting rod and the hole wall of the sliding hole, and the connecting rod makes rolling contact with the hole wall of the sliding hole through the rolling structure.

[0013] As an optional implementation, the rolling structure is a protrusion provided on at least one of the outer peripheral wall of the connecting rod and the inner wall of the sliding hole, and the contour surface of the protrusion is an arc-shaped surface.

[0014] As an alternative implementation, the protrusion is provided on the outer peripheral wall of the connecting rod.

[0015] The protrusion is integral with the connecting rod; or, the protrusion is movably embedded in the outer peripheral wall of the connecting rod.

[0016] As an alternative implementation, the protrusion is at least one of a spherical protrusion and a cylindrical protrusion.

[0017] As an optional implementation, the transmission mechanism includes a connector and a linkage unit. One end of the connector is connected to the bottom end of the connecting rod, and the other end is connected to the first end of the linkage unit. The second end of the linkage unit is pivotally connected to the end of the second locking member that is opposite to the first locking member.

[0018] As an optional implementation, the connector is a rod-shaped structure or a flexible structure.

[0019] When the connector is a rod-shaped structure, one end of the connector is pivotally connected to the bottom end of the connecting rod, and the other end is pivotally connected to the connecting rod unit.

[0020] As an optional implementation, the lifting member is a flexible lifting member, and the end of the lifting member opposite to the connecting rod is connected to one of the first housing and the second housing to form a ring structure.

[0021] As an optional implementation, the transmission mechanism further includes a second bearing, which is coaxially arranged with the connecting rod unit.

[0022] As an optional implementation, the linkage unit includes a first connecting arm and a second connecting arm connected to each other, the end of the first connecting arm opposite to the end of the second connecting arm being connected to the second locking member, and the end of the second connecting arm opposite to the end of the first connecting arm being connected to the connecting member.

[0023] Wherein, the length extension directions of the first connecting arm and the second connecting arm have an included angle, the included angle being greater than or equal to 30° and less than or equal to 90°.

[0024] And / or, the ratio of the length of the second connecting arm to the length of the first connecting arm is greater than or equal to 1 and less than or equal to 10.

[0025] As an optional implementation, the locking assembly further includes a stop member and an elastic member. The stop member is movably disposed on the second housing, and the elastic member is disposed between the stop member and the second housing. When the second locking member and the first locking member are unlocked from each other, the stop member moves between the first locking member and the second locking member under the elastic force of the elastic member.

[0026] And / or, the locking assembly further includes a resilient reset member connected between the second housing and the second locking member, the resilient reset member being configured to drive the second locking member toward the first locking member by its own elastic force.

[0027] The inspection equipment provided in this application, when the lifting member applies a lifting force, causes the connecting rod to move vertically. A transmission mechanism changes the direction of the driving force between the second locking member and the connecting rod, causing the second locking member to move horizontally and unlock itself from the first locking member. The vertical movement of the lifting member and connecting rod, converted by the transmission mechanism, becomes the horizontal movement of the second locking member. The lever effect of the transmission mechanism reduces the lifting force to overcome greater friction, making the unlocking process of the first and second locking members less strenuous, thereby reducing the difficulty of unlocking the locking components and improving the removal efficiency of the inspection equipment from power transmission lines.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] See Figure 1 , Figure 2 and Figure 3 This application provides an inspection device 100, including: a first housing 110, a second housing 120 and a locking assembly 130.

[0055] The first housing 110 and the second housing 120 are disposed opposite to each other and their first ends are rotatably connected. Their second ends move towards or away from each other under the influence of a force. When the first housing 110 and the second housing 120 approach each other, they can be fastened to the power transmission line. When the first housing 110 and the second housing 120 move away from each other, they can be detached from the power transmission line.

[0056] The locking assembly 130 includes a first locking member 131, a second locking member 132, a transmission mechanism 133, a connecting rod 134, and a lifting member 135. The first locking member 131 is fixed on the first housing 110, the second locking member 132 is movably disposed on the second housing 120, the second housing 120 has a vertically extending sliding hole 121, and the connecting rod 134 passes through the sliding hole 121; the transmission mechanism 133 is movably disposed on the second housing 120, and its two ends are respectively pivotally connected between the bottom ends of the second locking member 132 and the connecting rod 134, and the lifting member 135 is connected to the top end of the connecting rod 134.

[0057] When the first housing 110 and the second housing 120 are engaged, the first locking member 131 and the second locking member 132 are arranged horizontally and locked together. When an upward lifting force is applied to the lifting member 135, the lifting member 135 drives the connecting rod 134 to move upward, so that the connecting rod 134 is carried by the transmission mechanism 133 to the second locking member 132 to move away from the first locking member 131, until the first locking member 131 and the second locking member 132 are unlocked.

[0058] As will be understood by those skilled in the art, when the lifting member 135 applies a lifting force, the connecting rod 134 moves vertically. The direction of the driving force between the second locking member 132 and the connecting rod 134 is changed through the transmission mechanism 133, so that the second locking member 132 moves horizontally and unlocks itself from the first locking member 132. The vertical movement of the lifting member 135 and the connecting rod 134 is converted into the horizontal movement of the second locking member 132 through the transmission mechanism 133. The lever effect of the transmission mechanism 133 can reduce the lifting force to overcome the large frictional force, making the unlocking process of the first locking member 131 and the second locking member 132 less strenuous, thereby reducing the unlocking difficulty of the locking assembly 130 and improving the removal efficiency of the inspection equipment 100 from the power transmission line.

[0059] It should be noted that the shape of the sliding hole 121 and the shape of the connecting rod 134 in this embodiment match each other. For example, the sliding hole 121 can be a circular hole, a square hole, etc., and the shape of the corresponding peripheral sidewall of the connecting rod 134 can be a circle, a square, etc. This embodiment does not require this.

[0060] See Figure 3 The locking assembly 130 in this embodiment further includes a first bearing 136, which is located between the outer peripheral wall of the connecting rod 134 and the inner peripheral wall of the sliding hole 121.

[0061] For example, in this embodiment, the first bearing 136 can be a linear first bearing 136. The connecting rod 134 moves vertically in the inner hole of the linear first bearing 136. The connecting rod 134 contacts the rollers in the linear first bearing 136, changing the surface contact between the connecting rod 134 and the sliding hole 121 into point contact or line contact, thereby reducing the frictional force of the connecting rod 134. This allows a smaller lifting force to be applied to the lifting member 135 to unlock the first locking member 131 and the second locking member 132, further reducing the unlocking difficulty of the locking assembly 130 and improving the removal efficiency of the inspection equipment 100 from the power transmission line.

[0062] Optionally, a rolling structure is provided between the outer peripheral wall of the connecting rod 134 and the hole wall of the sliding hole 121, allowing the connecting rod 134 to roll into contact with the hole wall of the sliding hole 121. This transforms the sliding friction between the connecting rod 134 and the hole wall of the sliding hole 121 into rolling friction, resulting in smoother relative movement between the connecting rod 134 and the sliding hole 121. This makes the unlocking process of the first locking member 131 and the second locking member 132 smoother and faster, thereby improving the removal efficiency of the inspection equipment 100 from the power transmission line.

[0063] In some embodiments, the rolling structure can be a ball bearing, a cylindrical roller, or the like. The rolling structure also guides the movement of the connecting rod 134. This prevents the connecting rod 134 from deflecting, tilting, or jamming during vertical movement, further ensuring that the movement trajectory of the connecting rod 134 within the sliding hole 121 is always vertical. It also ensures that the first locking member 131 and the second locking member 132 can be unlocked stably and smoothly, and improves the disassembly efficiency of the inspection equipment 100.

[0064] In some embodiments, the rolling structure is a protrusion provided on at least one of the outer peripheral wall of the connecting rod 134 and the inner wall of the sliding hole 121, and the profile surface of the protrusion is an arc-shaped surface.

[0065] It should be noted that the rolling structure in this embodiment is only provided on the outer peripheral wall of the connecting rod 134, or the rolling structure is only provided on the inner wall of the sliding hole 121, or it can be provided on both the outer peripheral wall of the connecting rod 134 and the inner wall of the sliding hole 121.

[0066] When the rolling structure is set on the outer peripheral wall of the connecting rod 134 and the inner wall of the sliding hole 121, the rolling structure on the outer peripheral wall of the connecting rod 134 and the rolling structure on the inner wall of the sliding hole 121 will not interfere with each other.

[0067] For example, in this embodiment, the rolling structure is a protrusion, and the contour surface of the protrusion is an arc-shaped surface. It can be understood that the arc-shaped surface of the protrusion on the inner wall of the sliding hole 121 and the outer peripheral wall of the connecting rod 134 form point contact or line contact, which further reduces the motion friction between the sliding hole 121 and the connecting rod 134, so that the locking assembly 130 moves smoothly and stably during the unlocking process. It can also reduce the magnitude of the lifting force to avoid the accident of the drone tipping over and crashing due to uneven force during the application of force. While improving the disassembly efficiency, it also improves the safety of the disassembly operation of the inspection equipment 100.

[0068] Specifically, the protrusion is provided on the outer peripheral wall of the connecting rod 134; the protrusion and the connecting rod 134 are an integral structure; or, the protrusion is movably embedded in the outer peripheral wall of the connecting rod 134.

[0069] It should be noted that in this embodiment, the protrusion and the connecting rod 134 are an integral structure. That is to say, the protrusion can be made directly during the injection molding or metal processing of the connecting rod 134. Thus, there is no need to add a structure to fix the protrusion between the protrusion and the connecting rod 134, which simplifies the assembly process of the inspection equipment 100.

[0070] In some embodiments, a groove may be provided on the outer peripheral wall of the connecting rod 134, and the protrusion may be rotatably or rollingly connected to the outer peripheral wall of the connecting rod 134 through the groove. As those skilled in the art will understand, the protrusion embedded in the outer peripheral wall of the connecting rod 134 can reduce the weight of the connecting rod 134, thereby reducing the weight of the inspection device 100. Furthermore, since the diameter of the connecting rod 134 is relatively small, the size of the sliding hole 121 on the second housing 120 is also reduced accordingly. While satisfying the locking connection and easy unlocking of the inspection device 100, the size of the inspection device 100 can be further reduced.

[0071] For example, the protrusions in the embodiments of this application are at least one of spherical protrusions and cylindrical protrusions.

[0072] As will be understood by those skilled in the art, the protrusions on the outer peripheral wall of the connecting rod 134 can be spherical protrusions and / or cylindrical protrusions, and the protrusions on the inner wall of the sliding hole 121 can also be spherical protrusions and / or cylindrical protrusions.

[0073] In some embodiments, the spherical protrusions on the inner wall of the sliding hole 121 may be arranged in a ring, a row, or along the extension direction of the spiral. Similarly, the spherical protrusions on the outer peripheral wall of the connecting rod 134 may also be arranged in a ring, a row, or along the extension direction of the spiral. This application embodiment does not require such arrangement.

[0074] In some embodiments, the cylindrical protrusions on the inner wall of the sliding hole 121 may be arranged in a ring or in a row. Similarly, the cylindrical protrusions on the outer peripheral wall of the connecting rod 134 may also be arranged in a ring or in a row. This application embodiment does not require this arrangement.

[0075] See Figure 1 and Figure 2 The transmission mechanism 133 in this embodiment includes a connector 1331 and a linkage unit 1332. One end of the connector 1331 is connected to the bottom end of the connecting rod 134, and the other end is connected to the first end of the linkage unit 1332. The second end of the linkage unit 1332 is pivotally connected to the end of the second locking member 132 that is away from the first locking member 131.

[0076] It is easy to understand that the lifting component 135 lifts the connecting rod 134, the connecting rod 134 moves vertically, which drives the connecting component 1331 to move vertically. The connecting component 1331 further drives the linkage unit 1332 to rotate, and through the rotation of the linkage unit 1332, it drives the second locking component 132 to move horizontally toward the side where the linkage unit 1332 is located until the first locking component 131 and the second locking component 132 are completely unlocked.

[0077] During the rotation of the linkage unit 1332, the movement path of the end connected to the connecting member 1331 is arc-shaped, and the connecting member 1331 will swing in position, which can easily cause interference with other structural components in the second housing 120. As a result, the movement of the second locking member 132 in the horizontal direction toward the side where the linkage unit 1332 is located is blocked. That is to say, the second locking member 132 and the first locking member 131 cannot be completely unlocked.

[0078] Therefore, in this embodiment, the connector 1331 is a rod-shaped structure or a flexible structure. When the connector 1331 is a rod-shaped structure, one end of the connector 1331 is pivotally connected to the bottom end of the connecting rod 134, and the other end is pivotally connected to the connecting rod unit 1332. This connector 1331, and the connection structure between the connector 1331 and the connecting rod 134 and the connecting rod unit 1332, solves a series of problems caused by the swinging of the connector 1331.

[0079] For example, when the connector 1331 is a flexible structure, such as a flexible steel wire rope or cable, the two ends of the connector 1331 are respectively connected to the connecting rod 134 and the linkage unit 1332. When the linkage unit 1332 rotates, the flexibility of the connector 1331 can overcome the swing of the connector 1331 caused by the linkage unit 1332, so that the locking assembly 130 moves smoothly when unlocking, thereby improving the disassembly efficiency of the inspection equipment 100.

[0080] When the connector 1331 is a rod-shaped structure, the rigidity of the rod-shaped structure is much stronger than that of the flexible structure. At this time, the rod-shaped structure itself cannot overcome the swaying of the position through flexibility. Therefore, in this embodiment, the two ends of the connector 1331 are pivotally connected to the connecting rod unit 1332 and the connecting rod 134, respectively. That is to say, at the pivot point between the connector 1331 and the connecting rod unit 1332, the connector 1331 and the connecting rod 1332 can rotate, and at the pivot point between the connector 1331 and the connecting rod 134, the connector 1331 and the connecting rod 134 can rotate. This can overcome the obstruction of the connecting rod 134, the connector 1331 and the connecting rod unit 1332 during the movement, prevent the swaying interference caused by the rotation of the connecting rod unit 1332, thereby improving the smoothness of the movement of the inspection equipment 100 through the locking component 130, making the inspection equipment 100 easier to open, and further improving the disassembly efficiency of the inspection equipment 100.

[0081] See Figure 1The lifting member 135 is a flexible lifting member, and the end of the lifting member 135 facing away from the connecting rod 134 is connected to one of the first housing 110 and the second housing 120 to form a ring structure. Thus, at high altitudes, it is only necessary for the external structural member to pass through the ring structure and apply force to the lifting member 135; it is not necessary to completely fix the lifting member 135 to the external structural member. Furthermore, after the external structural member passes through the ring structure, it rises, and the flexible lifting member can actively attach itself to the external structural member. As the external structural member rises, a lifting force is generated between the external structural member and the flexible lifting member.

[0082] See Figure 2 The transmission mechanism 133 also includes a second bearing 1335, which is coaxially arranged with the connecting rod unit 1332. The coaxial arrangement of the connecting rod unit 1332 and the second bearing 1335 reduces the rotational friction of the connecting rod unit 1332 through the rollers of the second bearing 1335, thereby making the movement of the locking assembly 130 smooth.

[0083] Optionally, the linkage unit 1332 includes a first connecting arm 1333 and a second connecting arm 1334 connected to each other. The end of the first connecting arm 1333 opposite to the end of the second connecting arm 1334 is connected to a second locking member 132, and the end of the second connecting arm 1334 opposite to the end of the first connecting arm 1333 is connected to a connector 1331. The length extension directions of the first connecting arm 1333 and the second connecting arm 1334 have an included angle (α), which is greater than or equal to 30° and less than or equal to 90°; and / or, the ratio of the lengths of the second connecting arm 1334 and the first connecting arm 1333 is greater than 1 and less than or equal to 10.

[0084] Understandably, the connection between the first connecting arm 1333 and the second connecting arm 1334 is coaxially rotatably connected to the second bearing 1335. The first connecting arm 1333 and the second connecting arm 1334 form a lever mechanism to reduce the lifting force applied to the lifting member 135.

[0085] For example, α can be 30°, 45°, 60°, 90°, etc., and any angle value within the above range is acceptable. This application does not require such values.

[0086] Furthermore, the ratio of the lengths of the second connecting arm 1334 to the first connecting arm 1333 can be 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc., and any value within the above range is acceptable. This embodiment of the application does not require such a ratio. It can be understood that the length of the second connecting arm 1334 is greater than the length of the first connecting arm 1333, thereby forming a long lever arm and further reducing the lifting force applied to the lifting member 135.

[0087] See Figure 1 and Figure 4In this embodiment of the application, the locking assembly 130 further includes a stop member 137 and an elastic member 138. The stop member 137 is movably disposed on the second housing 120, and the elastic member 138 is disposed between the stop member 137 and the second housing 120. When the second locking member 132 and the first locking member 131 are unlocked from each other, the stop member 137 moves between the first locking member 131 and the second locking member 132 under the elastic force of the elastic member 138.

[0088] Thus, after the first locking member 131 and the second locking member 132 are fully unlocked, the abutment 137, located between the second locking member 132 and the first locking member 131 in the horizontal direction, prevents the first housing 110 and the second housing 120 from becoming stuck when the second locking member 132 moves toward the side where the first locking member 131 is located. In other words, the smoothness of the movement of the inspection equipment 100 is improved by such a locking assembly 130, thereby improving the disassembly efficiency of the inspection equipment 100.

[0089] It should be noted that the elastic element 138 can be directly connected to the second housing 120 and the blocking element 137, or a connecting structure can be provided on the second housing 120, and the elastic element 138 can be connected to the second housing 120 and the blocking element 137 through the connecting structure. This application embodiment does not require this.

[0090] See Figure 4 Optionally, the locking assembly 130 further includes a resilient reset member 139, which is connected between the second housing 120 and the second locking member 132. The resilient reset member 139 is configured to drive the second locking member 132 toward the first locking member 131 by its own elastic force. Thus, when re-locking is required after inspection and maintenance, the resilient reset member 139 acts on the second locking member 132 to lock the second locking member 132 and the first locking member 131 into a locked connection.

[0091] In some embodiments, the elastic reset member 139 may be sleeved on the second locking member 132, and both ends of the elastic attachment abut against the second housing 120 respectively, so that the movement of the second locking member 132 causes the elastic reset member 139 to generate elastic force, thereby driving the second locking member 132 to move toward the side where the first locking member 131 is located.

[0092] In some implementations, the elastic reset member 139 can be connected between the second locking member 132 and the second housing 120 through a connecting structure. The specific connection method between the elastic reset member 139, the second locking member 132, and the second housing 120 is not required in the embodiments of this application.

[0093] It should be noted that the embodiments referred to in the specification, such as "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments," may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0094] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" can be understood to convey either singular or plural usage.

[0095] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0096] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.
