Description

Technical Field

[0001] The invention relates to the technical field of cable fault detection, in particular to a cable identification instrument based on non-contact measurement technology. Background Art

[0002] The cable fault tester is mainly used to detect the location of cable faults. For example, it uses pulse reflection method and other technologies to determine the location of short circuit, open circuit or low resistance or high resistance fault points of the cable; the cable identifier is used to accurately identify the target cable among many cables, especially in complex cable network environments. Combining the two can not only solve the problem of cable identification during line construction and operation and maintenance, but also take into account functions such as cable fault finding, which will greatly facilitate actual work at the grassroots level.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the control mechanism is started, the first tool box moves up and breaks away from the contact with the second sliding plate. The elastic force of the second tension spring is used to move the lower part of the second sliding plate to the tool box position, driving the second movable plate to move up and complete the fixed connection. On the contrary, when the second bottom plate is no longer in contact with the first sliding plate, the first tension spring moves the first sliding plate up to lock and connect with the first bottom plate. The whole process is assisted by the limit sleeve and the plug-in block to ensure the safe storage of the detection tools, ensure the independence of the cable fault tester and the cable identifier during the detection, and ensure that the line connection between the two and the detection tools will not be confused.

[0016] 2. In the present invention, when it is necessary to take out the detection tool or workpiece, the user can pull the second bottom plate through the normally open top cover to make it slide smoothly along the sliding rod and easily extract the items in the second tool box. This sliding design ensures smooth operation and accelerates the use of workpieces and tools. When obtaining the detection tool in the first tool box, the lifting mechanism is started by pulling the handle, and the rotating frame rotates to drive the first transmission rod and the second transmission rod to move synchronously, thereby driving the lifting block to rise. The lifting rod realizes linear motion under the constraint of the first bottom plate, ensuring that the tool box moves upward stably and finally reaches the top of the inner cavity, which is convenient for the user to take out the detection tool.

[0017] 3. In the present invention, when the door leaf on one side of the side panel is opened, pulling the storage plate will synchronously drive the moving frame to move linearly along the slide rail, thereby pulling out the equipment on the inner side of the mounting ring, which is convenient for operators to access and operate. The moving frame not only provides support during the sliding process, but also links the first linkage rod and the second linkage rod. When the guide block slides in the guide hole, it is restricted by the first linkage rod and swings accordingly, thereby driving the lifting of the storage plate. The swing of the first linkage rod causes the storage plate to slowly lift, while the second linkage rod moves in coordination to ensure the smooth lifting of the storage plate and avoid tilting. The lifting trajectory of the storage plate is constrained by the guide hole to ensure smooth and controllable movement. Through the lifting of the storage plate, the operator can more conveniently access the equipment on the inner side of the mounting ring, realize rapid maintenance and overhaul, and significantly improve operating efficiency and safety.

Obviously, the implementation regulations described 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 creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown: a cable identification instrument based on non-contact measurement technology comprises a box body 1 and two top covers 2 rotatably connected on the top thereof, side panels 3 are installed on both sides of the box body 1, a frame 12 is installed on the inner side of the box body 1, a horizontal plate 11 is fixedly connected to the center of the inner cavity of the frame 12, a locking mechanism 5 is installed on the top of the horizontal plate 11, a control mechanism 4 is installed in the inner cavity of the box body 1, and two storage mechanisms 6 are installed at the bottom of the inner cavity of the box body 1; The locking mechanism 5 includes a first limiting sleeve 51 and a second limiting sleeve 56. The first limiting sleeve 51 is slidably connected to the first sliding plate 54 and the second moving plate 57. The first sliding plate 54 is provided with a first limiting hole 541 at the bottom end, and the first connecting rod 542 is fixedly connected to the side wall of the bottom end of the first sliding plate 54. The center of one side of the first limiting sleeve 51 is fixedly connected to the first side rod 511. One side of the first limiting sleeve 51 is provided with a first tension spring 52. The two ends of the first tension spring 52 are respectively suspended from the first side rod 511 and the first connecting rod 542. The second limiting sleeve 56 is slidably connected to the second sliding plate 54 at the inside. 5 and the first movable plate 53, the second side rod 561 is fixedly connected to the center of the side wall of the second limiting sleeve 56, and a second tension spring 58 is arranged on one side of the second limiting sleeve 56, one end of the second sliding plate 55 is fixedly connected to the second connecting rod 551, and one end of the second sliding plate 55 is provided with a second limiting hole 552, the first movable plate 53 is fixedly connected to the inner side of one end of the first movable plate 53, and the second movable plate 57 is fixedly connected to the inner side of the bottom end of the second movable plate 57, the second pushing rod 571 is slidably connected to the first limiting hole 541, and the first pushing rod 532 is slidably connected to the second limiting hole 552.

[0022] The bottom of the first limiting sleeve 51 is fixedly connected to the inner wall of the box body 1, the bottom of the second limiting sleeve 56 is fixedly connected to the transverse plate 11, one side of the first movable plate 53 is fixedly connected to the first plug-in block 531, and one end of the second movable plate 57 is fixedly connected to the second plug-in block 572.

[0023] In this embodiment, in the process of cable identification and fault detection, different tool boxes and equipment can be selected to achieve different functional requirements. The system is designed with two mounting rings 68, each of which is equipped with different equipment to independently complete their respective tasks. In order to facilitate identification and prevent the wrong use of tools during use, two tool boxes are designed: a first tool box 46 and a second tool box 47, which store different types of detection tools respectively. The storage and use of these tools are managed by the action of the control mechanism 4.

[0024] When the control mechanism 4 starts and controls the first tool box 46 to move upward, the first tool box 46 will break away from the contact with one end of the second sliding plate 55. At this time, the elastic force of the second tension spring 58 pulls the second sliding plate 55 through the interaction between the second side rod 561 and the second limiting hole 552, so that one end of the second sliding plate 55 moves to the lower position of the first tool box 46. In this process, the second limiting hole 552 at one end of the second sliding plate 55 will apply a force to the second push rod 571, thereby driving the second movable plate 57 to move upward. At the same time, the second movable plate 57 is constrained to slide under the constraint of the first limiting sleeve 51. As the second movable plate 57 rises, the second plug-in block 572 at the top is plugged into the bottom of the second bottom plate 48 to complete the fixed plug-in of the second bottom plate 48, thereby realizing the safe locking of the second tool box 47, ensuring the stable storage of the detection tools, and avoiding confusion during operation.

[0025] On the contrary, when the second bottom plate 48 has completed its movement and is no longer docked with the top of the first sliding plate 54, the elastic force of the first tension spring 52 will pull the first connecting rod 542, so that it drives the first sliding plate 54 to move upward. In this process, the first sliding plate 54 applies force to the first push rod 532 through the first limit hole 541, so that the first push rod 532 transmits this force to the first movable plate 53. Under the restriction of the second limit sleeve 56, the first movable plate 53 will slide upward along the guide path, and finally drive the first plug-in block 531 to plug with the side wall of the first bottom plate 461, thereby completing the locking of the first tool box 46. This process ensures the safe locking of the first tool box 46, avoids the mistaking and confusion of tools during the detection operation, ensures the work efficiency and accuracy of identification and fault detection, and ensures the independence of the cable fault tester and the cable identifier during the detection, and the line connection between the two and the detection tools will not be confused.

[0026] Embodiment 2: Figure 1 - Figure 4As shown, the control mechanism 4 includes a first bottom plate 461 and a second bottom plate 48. A first tool box 46 is installed on the top of the first bottom plate 461. Two limit blocks 462 are symmetrically arranged at the bottom of the first tool box 46. The inner side of the limit block 462 is slidably fixedly connected with the lifting rod 44, and the limit block 462 is fixedly connected to the cross plate 11. One side of the limit block 462 is rotatably connected to the rotating frame 43, one end of the rotating frame 43 is rotatably connected to the first transmission rod 42, and the top of the rotating frame 43 is fixedly connected to the handle 41, and the bottom end of the lifting rod 44 is fixedly connected to the lifting block 452. The bottom end of the first transmission rod 42 is rotatably connected to the second transmission rod 45, and the bottom end of the second transmission rod 45 is rotatably connected to the lifting block 452. A stopper 451 is arranged at the bottom of the lifting block 452, and the stopper 451 is fixedly connected to the inner wall of the box body 1. A second tool box 47 is installed on the top of the second bottom plate 48 , and both ends of the bottom end of the second bottom plate 48 are slidably connected to slide rods 49 , and both ends of the slide rods 49 are fixedly connected to the inner wall of the box body 1 .

[0027] In this embodiment, during use, the two top covers 2 on the top play different functions, one is in a normally open state, which is convenient to open at any time, and the other is always locked to protect the equipment and tools inside. When it is necessary to take out the detection tool or workpiece, the normally open top cover 2 can be opened, and the second bottom plate 48 can be pulled to slide along the surface of the slide rod 49, so as to easily take out the items stored in the second tool box 47. This sliding design not only ensures the smoothness of operation, but also facilitates the quick access of workpieces and tools.

[0028] When taking out the detection tools in the first tool box 46, it is necessary to control its rise to achieve the purpose of convenient access. First, by pulling the handle 41, the rotating frame 43 is driven to rotate, and then the first transmission rod 42 starts to move synchronously with the rotating frame 43. At the bottom end of the rotating frame 43, the second transmission rod 45 is driven to drive the lifting block 452 to start moving. As the lifting block 452 rises, the lifting rod 44 also moves upward.

[0029] During the entire ascending process, the lifting rod 44 is constrained by the first bottom plate 461 to achieve straight-line movement up and down to ensure stability. When the lifting rod 44 gradually rises, it pushes the first bottom plate 461 to move upward together, so that the first tool box 46 is pushed to the top position of the inner cavity of the box body 1, and the user can easily take out the detection tools therein.

[0030] Embodiment 3: According to Figure 7 and Figure 8As shown, the storage mechanism 6 includes a shell 61 and a storage plate 66. The bottom of both sides of the inner cavity of the shell 61 are fixedly connected with slide rails 611. One end of the storage plate 66 is fixedly connected with a mobile frame 67, and the mobile frame 67 is slidably connected to the slide rails 611. The top of the storage plate 66 is fixedly connected with a mounting ring 68, and the cable identification instrument body or the cable fault detector body is installed inside the mounting ring 68. The inner wall of the shell 61 is fixedly connected with a fixed plate 62, and a guide hole 63 is opened in the middle of the fixed plate 62. The side wall of the mobile frame 67 is rotatably connected with a second linkage rod 65, and the inner side of the guide hole 63 is slidably connected with a guide block 641, and one end of the guide block 641 is fixedly connected with a first linkage rod 64. One end of the first linkage rod 64 is rotatably connected to the side wall of the storage plate 66, and the bottom end of the second linkage rod 65 is rotatably connected to the side wall of the storage plate 66.

[0031] In this embodiment, when the door leaf on one side of the side panel 3 is opened, the storage plate 66 can be pulled, and this action will drive the moving frame 67 to move synchronously. The moving frame 67 moves in a straight line under the guidance and restriction of the slide rail 611, so as to pull out the equipment inside the mounting ring 68, which is convenient for operators to take and operate. In the pulling-out process, the moving frame 67 not only plays a supporting role, but also links the first linkage rod 64 and the second linkage rod 65.

[0032] As the guide block 641 slides inside the guide hole 63, the guide block 641 is restricted by the guide hole 63, driving the first linkage rod 64 to swing. This swing drives the lifting function of the storage plate 66. The swing of the first linkage rod 64 causes the storage plate 66 to slowly lift up. At the same time, the second linkage rod 65 cooperates with the action of the first linkage rod 64 to keep the storage plate 66 rising steadily and avoid tilting. The lifting trajectory of the storage plate 66 is constrained by the guide hole 63, thereby ensuring the stability and controllability of the movement.

[0033] By lifting the storage plate 66, the operator can more conveniently access the equipment inside the mounting ring 68, thereby achieving rapid maintenance and inspection of the equipment.

[0034] The use method and working principle of the device: When identifying and fault-detecting cables, different tool boxes and equipment can be selected. Different equipment is configured inside the two mounting rings 68 to perform different tasks, and different types of detection tools are stored in the first tool box 46 and the second tool box 47 to avoid the situation of mistakenly taking tools during use.

[0035] When the control mechanism 4 controls the first tool box 46 to move upward, the first tool box 46 will be separated from the contact with one end of the second sliding plate 55, so that the elastic force of the second tension spring 58 pulls the second sliding plate 55 through the second side rod 561 and the second limiting hole 552, and moves one end of the second sliding plate 55 to the bottom of the first tool box 46. In this process, the second limiting hole 552 at one end of the second sliding plate 55 exerts a force on the second push rod 571, so that the second movable plate 57 starts to move upward and moves under the restriction of the first limiting sleeve 51. As the second plug-in block 572 at the top of the second movable plate 57 is plugged into the bottom of the second bottom plate 48, the locking of the second bottom plate 48 is completed.

[0036] On the contrary, when the second bottom plate 48 moves and detaches from the top of the first sliding plate 54, the elastic force of the first tension spring 52 pulls the first connecting rod 542, thereby driving the first sliding plate 54 to move upward. In this process, the first sliding plate 54 applies a force to the first push rod 532 through the first limiting hole 541, thereby causing the first push rod 532 to transmit the force to the first movable plate 53. As the first movable plate 53 slides under the limit of the second limiting sleeve 56, the first plug-in block 531 plugs into the side wall of the first bottom plate 461, thereby completing the locking of the first tool box 46, so as to prevent the internal tools of the first tool box 46 and the second tool box 47 from being mixed during use.

[0037] The two top covers 2 at the top are respectively set to be normally open and normally locked. When it is needed, the normally open top cover 2 can be opened, and the second bottom plate 48 can be pulled to slide on the surface of the slide bar 49, so as to facilitate the removal of the workpieces and detection tools in the second tool box 47. When the first tool box 46 is controlled to rise, the handle 41 is pulled, which will drive the rotating frame 43 to rotate, so that the first transmission rod 42 moves with the rotating frame 43. In this process, the second transmission rod 45 at the bottom end of the rotating frame 43 drives the lifting block 452 to move, and the movement of the lifting block 452 then drives the lifting rod 44 to move upward. Under the restriction of the first bottom plate 461, the lifting rod 44 realizes a straight line up and down movement, thereby pushing the first tool box 46 to the top of the inner cavity of the box body 1, so as to facilitate the removal of the internal detection tools.

[0038] When the door leaf on one side of the side panel 3 is opened and the storage plate 66 is pulled, the movable frame 67 will be driven to move. At this time, the movable frame 67 moves linearly under the restriction of the slide rail 611, and pulls out the equipment in the mounting ring 68. During the pulling process, the movable frame 67 will also drive the first linkage rod 64 and the second linkage rod 65 to move, and the guide block 641 slides in the guide hole 63, and is restricted by the guide hole 63, so that the first linkage rod 64 swings. Through the swing of the first linkage rod 64, the storage plate 66 begins to rise and fall. With the cooperation of the second linkage rod 65, the storage plate 66 is lifted, and the trajectory is restricted by the guide hole 63. This lifting and lowering movement makes it convenient for operators to use the equipment in the mounting ring 68.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
