Description

Technical Field

[0001] The present invention relates to the technical field of bridge detection, and in particular to a handheld image acquisition and detection device with an automatic telescopic function. Background Art

[0002] During bridge inspection, it is often necessary to conduct local key inspections on certain special parts of the bridge. These key inspection areas are mostly located in high, low places or certain corners, and the user is 5 to 6 meters away from the inspection area. The more conventional method currently is manual climbing, which has problems such as low operating efficiency and high risk.

[0003] For example, patent publication number CN209054312U, titled "A Shooting Pole for Power Grid Inspection," uses a telescopic rod structure that can be stretched to the required length for easy operation by inspectors. A shaped hose is provided between the telescopic rod and the camera, allowing the camera to be bent in any direction.

[0004] For example, the patent publication number CN205123833U, “An Automatic Telescopic Selfie Stick,” uses a pull-cord mechanism to achieve synchronous telescopic extension of multiple sections of telescopic rods;

[0005] However, the telescopic rod used in bridge inspection is long, and there are many places that need to be inspected. In addition, there are many components integrated inside the telescopic rod, which makes it heavy. Holding the telescopic rod for a long time can easily cause muscle soreness. Summary of the Invention

[0006] The object of the present invention is to provide a handheld image acquisition and detection equipment with automatic telescopic function to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A handheld image acquisition and detection device with automatic telescopic function, comprising a multi-section telescopic rod and a display, wherein a shooting assembly is mounted on the telescopic end of the multi-section telescopic rod via a shaped hose, and the display is electrically connected to the shooting assembly;

[0009] The device further comprises a bracket, wherein a battery assembly for providing power is disposed on the bracket, a shoulder strap is disposed on one side of the bracket, a horizontally extending rotating shaft is disposed on a side wall of the bracket, a first connector is movably sleeved on an outer wall of the rotating shaft, and the first connector is electrically connected to the battery assembly;

[0010] The handheld end of the multi-section telescopic rod is provided with a second connector, and the second connector can be plugged and electrically connected to the first connector.

[0011] Preferably, the shooting assembly includes a second support connected to the end of the shaping hose and driven to rotate around a first axis by a first power assembly, a first support is provided on the second support, and an endoscopic video collector is provided on the first support and driven to rotate around a second axis by a second power assembly, and the first axis and the second axis are perpendicular to each other.

[0012] Preferably, the multi-section telescopic rod includes an odd number of sleeves of more than three sections that are arranged in sequence, and the three adjacent groups of sleeves are connected by a pull rope mechanism. An electric telescopic rod is arranged in the sleeve for hand-holding, and the output end of the electric telescopic rod is connected to another adjacent group of sleeves.

[0013] Preferably, a controller is installed on the outer side wall of the sleeve for hand-holding.

[0014] Preferably, the display is detachably snap-connected to the outer wall of the handheld end of the multi-section telescopic rod.

[0015] Preferably, the bracket is in an "L"-shaped structure, and a storage bag is provided at the top of the vertical end of the bracket of the "L"-shaped structure, and the battery assembly is accommodated in the storage bag.

[0016] Preferably, a supporting telescopic rod is provided on the first connector.

[0017] Preferably, one end of the supporting telescopic rod is connected to or separated from the first connector through a clutch assembly.

[0018] Preferably, a hinge seat is sleeved on the outer wall of the rotating shaft, and first spline teeth are evenly arranged on the outer wall of one end of the first connector around the axis of the rotating shaft. The supporting telescopic rod is linearly slidably engaged with the hinge seat, and a second spline block engaged with the first spline teeth is provided at one end of the supporting telescopic rod, and an elastic member is connected between the second spline block and the hinge seat.

[0019] Preferably, the multi-section telescopic rod and the supporting telescopic rod are made of carbon fiber or glass fiber.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention transports the shooting component to the area to be detected by telescoping a multi-section telescopic rod, and receives a video image of the detection area through a display to achieve the detection purpose.

[0022] The various sleeves in the multi-section telescopic rod are connected by a pull-rope mechanism. The pull-rope mechanism has fewer parts and is lighter in weight, so that the overall weight of the multi-section telescopic rod is lower. In addition, the heavier electric telescopic rod that drives the multi-section telescopic rod to extend and retract is set close to the user's wrist, which helps to reduce the effort consumed by the user to operate the multi-section telescopic rod.

[0023] The shooting component itself can rotate and cooperate with the shaped hose, which is conducive to solving the problem of being located at a high (low) place on the bridge and having a certain angle that is not convenient for straight rod detection.

[0024] The battery assembly and other components that are large in size and weight are installed on the bracket, which can be conveniently carried on the user's back through a shoulder strap. By utilizing the shoulders and spine to bear part of the force, the load on the hands is reduced, and the problem of muscle soreness caused by holding the multi-section telescopic pole for a long time is reduced.

[0025] The support is provided by supporting the telescopic rod in contact with the ground and forming a multi-section telescopic rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Example 1:

[0036] A handheld image acquisition and detection equipment with automatic telescopic function, such as Figure 1-3 As shown, it includes a bracket 1, a storage bag 2, a battery assembly 21, a rotating shaft 3, a shoulder strap 4, a multi-section telescopic rod 5, a shaping hose 6, a shooting assembly 7, a display 8 and a controller 9.

[0037] The bracket 1 has an "L"-shaped structure. A shoulder strap 4 is provided on the side of the vertical end of the bracket 1 facing away from the horizontal end. A storage bag 2 is installed on the top of the horizontal end of the bracket 1. The bracket 1 is carried on the user's back through the shoulder strap 4; the battery assembly 21 is placed in the storage bag 2, and the storage bag 2 can also be used to place other tools.

[0038] A rotating shaft 3 is provided on the side wall of the bracket 1 extending horizontally outward, and a clamping hole is opened on the handheld end of the multi-section telescopic rod 5, which is adapted to the outer diameter of the rotating shaft 3. The handheld end of the multi-section telescopic rod 5 can be detachably sleeved on the outer wall of the rotating shaft 3 through the clamping hole, and the handheld end of the multi-section telescopic rod 5 can be rotated relative to the rotating shaft 3; the multi-section telescopic rod 5 can be detached from the rotating shaft.

[0039] like Figure 3 As shown, the multi-section telescopic rod 5 includes multiple sets of sleeves 51, electric telescopic rods 52 and pull rope mechanisms 53 that are sequentially arranged. The number of sleeves 51 is at least three and the number is an odd number. Two adjacent sleeves 51 are linearly slidably engaged with each other. The outermost first set of sleeves 51 is configured as the handheld end of the multi-section telescopic rod 5 for handholding and has a clamping hole. The outer wall of this sleeve 51 is fixedly mounted with a controller 9. The electric telescopic rod 52 is installed in this sleeve 51. The output end of the electric telescopic rod 52 is connected to the second set of sleeves 51. The three adjacent sets of sleeves 51 are connected by a pull rope mechanism 53.

[0040] The electric telescopic rod 52 is extended and retracted to drive the second set of sleeves 51 to move relative to the first set of sleeves 51 to adjust the spacing. During this process, the rope mechanism 53 drives the other sleeves 51 to move synchronously.

[0041] like Figure 3As shown, it is assumed that there are three groups of casings 51, and the rope pulling mechanism 53 includes a first rope, a second rope, a first guide wheel and a second guide wheel. The first guide wheel and the second guide wheel are installed on the second group of casings 51; one end of the first rope is fixed to the side wall of the first group of casings 51, and the other end of the first rope is fixed to the third group of casings 51 after being deflected by the first guide wheel; one end of the second rope is fixed to the side wall of the first group of casings 51, and the other end of the second rope is fixed to the third group of casings 51 after being deflected by the second guide wheel;

[0042] During the process of the electric telescopic rod 52 extending and retracting to drive the second group of sleeves 51 to move relative to the first group of sleeves 51 to adjust the spacing, since the lengths of the first pull rope and the second pull rope remain unchanged, during this process, the first pull rope and the second pull rope cooperate to drive the third group of sleeves 51 to move the same distance relative to the second group of sleeves 51.

[0043] The heavier electric telescopic rod 52 is installed in the first set of sleeves 51 for hand-holding. Even when the multi-section telescopic rod 5 is extended, the heavier part is always close to the hand-holding part. In addition to the weight of the other sleeves 51, there is only the pull rope mechanism 53. This makes the multi-section telescopic rod 5 light and convenient for users to hold.

[0044] A shaping hose 6 is mounted on the free end of the multi-section telescopic rod 5, which is away from the handheld end. The shaping hose 6 can be a shapeable coiled tube, and the user can manually change the shape of the shaping hose 6. The shaping hose 6 can be fixed when no external force is applied. A camera assembly 7 is mounted on the free end of the shaping hose 6. The manually changeable shape of the shaping hose 6 facilitates the use of the camera assembly 7 in non-linear detection situations.

[0045] The shooting assembly 7 includes an endoscopic video collector 71, a first support 72 and a second support 73 of a U-shaped structure. The endoscopic video collector 71 is relatively small in size and mass. The first support 72 and the second support 73 are fixedly connected as a whole. The second support 73 is rotatably connected to the free end of the shaped hose 6. A first power assembly is installed in the free end of the shaped hose 6. The first power assembly drives the second support 73 to rotate at the free end of the shaped hose 6. The endoscopic video collector 7 is installed on the inner side of the first support 72 of the U-shaped structure. A second power assembly is installed on the first support 72. The second power assembly drives the endoscopic video collector 7 to rotate relative to the first support 72. The rotation axes of the endoscopic video collector 7 and the second support 73 are perpendicular to each other, thereby enabling the endoscopic video collector 7 to rotate in any direction in space.

[0046] The endoscopic video collector 71 has a strong light source, which makes it easy to use in places with insufficient light.

[0047] The first power assembly and the second power assembly can be micro motors. The first power assembly, the second power assembly and the electric telescopic rod 52 are all electrically connected to the controller 9.

[0048] The endoscopic video collector 7 can transmit data to the display 8 via a local area network, Bluetooth or a wired method. The display 8 is detachably mounted on the handheld end of the multi-section telescopic rod 5 by bolts / snaps. The display 8 can also be fixed to the handheld end of the multi-section telescopic rod 5 or set independently.

[0049] Working principle:

[0050] The user holds the handheld end of the multi-section telescopic rod 5, and controls the multi-section telescopic rod 5 to extend and retract through the controller 9 located at the handheld part of the multi-section telescopic rod 5, and controls the first power component and the second power component to drive the endoscopic video collector 71 to adjust its direction through the controller 9.

[0051] Electrical wires and signal lines for the first and second power components, the electric telescopic rod 52, the controller 9, the display 8, and other electrical components extend from the handheld end of the multi-section telescopic rod 5 and are electrically connected to the battery assembly 21. The battery assembly 21 is placed in the storage bag 2. Other electrical components not mentioned in this solution are also placed in the storage bag 2 to avoid unnecessary weight added to the multi-section telescopic rod 5 by installing other electrical components.

[0052] The display 8 displays the images captured by the endoscopic video collector 71 in real time.

[0053] Example 2: Figure 4-5 The embodiment 1 includes all the contents, except that:

[0054] A first connector 31 is movably provided on the outer wall of the rotating shaft 3, and the first connector 31 is electrically connected to the battery assembly 21. A second connector 501 is provided on the handheld end of the multi-section telescopic rod 5 (the outermost first group of sleeves 51). A battery is provided in the handheld end of the multi-section telescopic rod 5. The battery is small in size and can temporarily power the electrical components on the multi-section telescopic rod 5.

[0055] The first connector 31 and the second connector 501 are detachably pluggable, which can realize both power transmission and signal transmission; the first connector 31 can adopt a USB plug or a Type-C plug, etc., and the second connector 501 can adopt a corresponding USB socket or a Type-C socket, etc.

[0056] When the first connector 31 and the second connector 501 are plugged and electrically connected, the battery assembly 21 charges the battery in the multi-section telescopic rod 5. The first connector 31 and the second connector 501 are separated, so that the multi-section telescopic rod 5 can be separated from the bracket 1 for more flexible use.

[0057] The supporting telescopic rod 32 is an electric telescopic rod, and the controller 9 is used to control the extension and retraction of the supporting telescopic rod 32.

[0058] One end of the first connector 31 is provided with a first spline tooth 311, and the first spline teeth 311 are evenly distributed circumferentially around the axis of the rotating shaft 3. The hinge seat 33 is hinged on the outer wall of the rotating shaft 3. The upper part of the supporting telescopic rod 32 slides with the hinge seat 33 in a straight line (along the telescopic direction of the supporting rod 32). A second spline block 321 is fixedly provided on the upper end of the supporting telescopic rod 32. An elastic member is connected between the second spline block 321 and the hinge seat 33. The elastic force of the elastic member drives the second spline block 321 to move away from the first spline tooth 311.

[0059] Working principle:

[0060] In some situations, it is necessary to hold the multi-section telescopic rod 5 for a long time, and the multi-section telescopic rod 5 needs to maintain a specific state for a period of time. At this time, the controller 9 controls the support telescopic rod 32 to extend, so that the lower end of the support telescopic rod 32 abuts against the ground. The reaction of the abutment of the lower end of the support telescopic rod 32 against the ground pushes the upper end of the support telescopic rod 32 to move upward, so that the second spline block 321 moves upward and engages with the first spline teeth 311. At this time, the multi-section telescopic rod 5 is fixedly connected to the support telescopic rod 32, and the support of the multi-section telescopic rod 5 is achieved by the abutment of the support telescopic rod 32 with the ground.

[0061] The user stands slightly higher so that the lower end of the supporting telescopic rod 32 is separated from the ground. Under the action of the elastic member, the second spline block 321 and the first spline teeth 311 are separated. At this time, the multi-section telescopic rod 5 can rotate around the rotating shaft 3.
