[0022] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Application Overview

[0024] As a crucial component of power supply equipment, power transmission lines require routine inspection and maintenance. Among these, assessing cable quality is of paramount importance. This assessment often necessitates the use of diagnostic devices. These devices primarily perform their checks by scanning the cables; therefore, they must accompany the personnel to the designated location during operation.

[0025] In existing technologies, diagnostic devices used for circuit testing typically consist of two parts: a diagnostic instrument and a mounting bracket. Before use, the diagnostic instrument is bolted to the mounting bracket, and to ensure a stable and secure installation, the bolts need to be tightened using appropriate tools. After installation, the mounting bracket is used to move the diagnostic instrument to the designated location. However, installing the diagnostic instrument using bolts is time-consuming, resulting in low overall installation efficiency and impacting the work efficiency of personnel.

[0026] This application provides a mounting structure for supporting main equipment and a power transmission line diagnostic device. Metal pillars are installed on a mounting plate, and fixing blocks and snap-fit ​​structures are pre-installed on the main equipment. During installation, the main equipment is simply placed on the mounting plate, and the metal pillars are simultaneously inserted into fixing holes. The snap-fit ​​structures then secure the metal pillars, thus fixing the main equipment to the mounting plate. Furthermore, limiting grooves can be cut into the mounting plate to embed parts of the main equipment, improving installation stability. A drive mechanism can also be added to the mounting plate, allowing the mounting plate to move, which in turn moves the main equipment. This allows the main equipment to move with the operator, further improving portability and eliminating the need for the operator to carry it. This not only effectively improves the installation efficiency of the main equipment but also reduces the burden on the operator.

[0027] After briefly introducing the implementation principle of this application, the following describes various non-limiting embodiments of this application in detail with reference to the accompanying drawings.

[0028] Exemplary support structure for main equipment fixing

[0029] Figure 1 The diagram shown is a structural schematic of the fixing structure of the supporting main equipment in some embodiments of this application. Figure 2 As shown Figure 1 Enlarged view of part A in the implementation shown. Figure 3 As shown Figure 1 An enlarged view of part B in the implementation shown. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 As shown, the supporting structure for the main equipment includes: a fixing plate 100, a fixing block 200, a fixing post 300, and a snap-fit ​​mechanism 400. The fixing plate 100 has a first limiting groove 110, configured to support and accommodate a portion of the main equipment 500. The fixing block 200 is disposed on the main equipment 500, and has a second limiting groove 210 and a fixing hole 220. The fixing post 300 is disposed on the fixing plate 100 and inserted into the fixing hole 220. The snap-fit ​​mechanism 400 is disposed within the second limiting groove 210, and configured to partially insert into or disengage from the fixing post 300.

[0030] Specifically, the first limiting groove 110 is formed on the top wall of the fixing plate 100. The first limiting groove 110 can be a rectangular groove, which facilitates circumferential limiting of the main equipment 500 placed within the first limiting groove 110. The first limiting groove 110 extends vertically. The fixing post 300 is made of metal. The bottom wall of the fixing post 300 can be fixedly connected to the top wall of the fixing plate 100 by welding or bolts. The fixing block 200 is fixed on the side of the main equipment 500. The fixing hole 220 extends vertically, and the top of the fixing post 300 can be inserted into the fixing hole 220. The fixing hole 220 can be a round hole, and the fixing post 300 can be a cylinder, and the diameter of the round hole can be larger than the diameter of the cylinder. The snap-fit ​​mechanism 400 is used to fix the fixing post 300 when it is inserted into the fixing hole 220. The snap-fit ​​mechanism 400 can partially pass through the side wall of the fixing hole 220 and be inserted into the fixing post 300. When it is necessary to remove the main body equipment 500 from the fixing plate 100, the snap-fit ​​mechanism 400 is first disengaged from the fixing post 300, the fixing post 300 is disengaged from the fixing hole 220, and then the main body equipment 500 is removed from the fixing plate 100.

[0031] The main equipment mounting structure provided in this application allows the main equipment 500 to be placed on the mounting plate 100 during installation. The first limiting groove 110 limits its position, and the mounting post 300 is simultaneously inserted into the mounting hole 220. When the mounting post 300 is inserted into the mounting hole 220, the snap-fit ​​mechanism 400 snaps it in place, thus achieving a fixed connection between the mounting post 300 and the mounting block 200. The mounting block 200 is mounted on the main equipment 500, thereby achieving a fixed installation of the main equipment 500 and the mounting plate 100. By using the snap-fit ​​mechanism 400 to fix the mounting post 300, the main equipment 500 can be installed quickly, effectively improving the installation efficiency.

[0032] Reference Figure 2As shown, in some embodiments of this application, the latching mechanism 400 includes: a latching block 410, a pressing block 420, a latching plate 430, an elastic member 440, and an insertion portion 450. The latching block 410 is connected to the fixing block 200. The pressing block 420 is disposed within the second limiting groove 210. The second limiting groove 210 may be formed on the side wall of the fixing block 200 away from the main body device 500, so that the second limiting groove 210 forms a notch. The latching block 410 may be part of the fixing block 200 or may be disposed separately. When the latching block 410 is part of the fixing block 200, the latching block 410 may be part of the side wall below the second limiting groove 210. The latching plate 430 is connected to the pressing block 420, and the latching plate 430 latches with the latching block 410. The elastic member 440 is connected to the pressing block 420, so that the pressing block 420 can move in the first direction X. The insertion part 450 is connected to the elastic member 440; wherein, the fixing post 300 is provided with a third limiting groove 310, and the insertion part 450 can penetrate the fixing block 200 in the second direction Y to insert into the third limiting groove 310 or disengage from the third limiting groove 310.

[0033] Specifically, the first direction X is the axial extension direction of the fixed post 300, and the second direction Y can be perpendicular to the first direction X. The pressing block 420 can slide along the first direction X, and the snap-fit ​​plate 430 is disposed on the bottom wall of the pressing block 420. The side of the snap-fit ​​plate 430 away from the pressing block 420 can be snapped into or disengaged from the snap-fit ​​block 410. The elastic element 440 can be a spring, with one end of the spring fixedly connected to the pressing block 420 and the other end of the spring fixedly connected to the insertion part 450, and the elastic extension direction of the spring extends in the first direction X.

[0034] Before the fixing post 300 is inserted into the fixing hole 220, pressure is applied to the top wall of the pressing block 420, causing the pressing block 420 to slide downwards along the first direction X. At the same time, the snap-fit ​​plate 430 also slides downwards synchronously, thus releasing the snap-fit ​​between the snap-fit ​​plate 430 and the snap-fit ​​block 410, and the elastic element 440 is simultaneously in a compressed state. Then, the pressing block 420 is dragged along the second direction Y, which will cause the pressing block 420 to move away from the fixing hole 220. At this time, the fixing post 300 is then inserted into the fixing hole 220.

[0035] After the fixing post 300 is inserted into the fixing hole 220, the pressing block 420 is pulled back along the second direction Y. The insertion part 450 will then pass through the fixing block 200 and insert into the third limiting groove 310, locking the fixing post 300. Then, the pressing block 420 is released. Because the elastic element 440 is in a compressed state, the elastic element 440 will push the pressing block 420 to slide upward along the first direction X. The pressing block 420 will then reset under the action of the elastic element 440, simultaneously causing the locking plate 430 to engage with the locking block 410, thereby fixing the insertion part 450. This completes the fixing of the fixing post 300.

[0036] Reference Figure 2 As shown, in some embodiments of this application, the fixing block 200 has an L-shaped through hole 411 extending to the second limiting groove 210, the snap-fit ​​plate 430 is an L-shaped plate, one end of the snap-fit ​​plate 430 is connected to the pressing block 420, and the snap-fit ​​plate 430 extends into the L-shaped through hole 411 so as to snap-fit ​​with the snap-fit ​​block 410.

[0037] Specifically, the L-shaped plate comprises a vertical plate and a horizontal plate. The top wall of the vertical plate is fixedly connected to the bottom wall of the pressing block 420, while the horizontal plate extends towards the side away from the fixing post 300. The top wall of the horizontal plate engages with the bottom wall of the locking block 410. Simultaneously, there is a gap between the vertical plate and the locking block 410 that allows sliding along the second direction Y, and a gap between the horizontal plate and the locking block 410 that allows sliding along the first direction X.

[0038] By setting an L-shaped plate, when the pressing block 420 needs to slide, the pressing block 420 is first moved down, thereby separating the horizontal plate from the locking block 410. Then, the pressing block 420 is pulled to slide along the second direction Y, and the L-shaped plate can slide along with the pressing block 420. When fixing is required, simply engage the horizontal plate of the L-shaped plate with the locking block 410 to fix the pressing block 420.

[0039] Reference Figure 2 As shown, in some embodiments of this application, the snap-fit ​​plate 430 is provided with a protrusion 431, and the inner wall of the L-shaped through hole 411 is provided with a groove 412. Alternatively, the snap-fit ​​plate 430 is provided with a groove 412, and the inner wall of the L-shaped through hole 411 is provided with a protrusion 431. The protrusion 431 and the groove 412 can engage in a convex-concave fit so that the snap-fit ​​plate 430 is inserted into the inner wall of the L-shaped through hole 411 in the first direction X.

[0040] Specifically, a protrusion 431 is provided on the top wall of the horizontal plate of the L-shaped plate. Multiple protrusions 431 can be provided, or they can be elongated. Multiple grooves 412 can also be provided, or they can be elongated. When the snap-fit ​​plate 430 needs to be fixed, the protrusion 431 is inserted into the groove 412. After being inserted along the first direction X, the protrusion 431 abuts against the side wall of the groove 412, which can restrict the movement of the snap-fit ​​plate 430 in the second direction Y. This can prevent the insertion part 450 from disengaging from the fixing post 300 due to accidental contact with the pressing block 420.

[0041] In some embodiments of this application, the insertion portion 450 includes: an insertion block 451, a connecting portion 452, and a connecting post 453. The connecting portion 452 is connected to the side of the insertion block 451 away from the fixing post 300. One end of the connecting post 453 is connected to the connecting portion 452, and the connecting post 453 extends along a first direction X. The fixing block 200 has a first through hole 230 extending along a second direction Y, so that the insertion block 451 can pass through the fixing block 200, and the insertion block 451 passing through the fixing block 200 can cooperate with the third limiting groove 310 of the fixing post 300. The pressing block 420 has a second through hole 421 extending along the second direction Y to accommodate the connecting part 452 and the connecting post 453. The inner wall of the second through hole 421 has a connecting hole 422. The connecting post 453 extends partially into the connecting hole 422. There is a sliding gap 423 between the connecting post 453 and the connecting hole 422. One end of the elastic member 440 is connected to the connecting post 453, and the end of the elastic member 440 away from the connecting post 453 is fixedly connected to the hole wall of the connecting hole 422.

[0042] Specifically, the first connecting hole 230 is located between the second limiting groove 210 and the fixing hole 220. One end of the first connecting hole 230 is connected to the second limiting groove 210, and the other end of the first connecting hole 230 is connected to the fixing hole 220. The plug-in block 451 can slide within the first connecting hole 230, and the length of the plug-in block 451 is greater than the length of the first connecting hole 230. In order to avoid circumferential rotation of the plug-in block 451, the cross-section of the plug-in block 451 can be rectangular, and the first connecting hole 230 is also a rectangular hole, so that the plug-in block 451 and the inner wall of the first connecting hole 230 can form a surface-to-surface fit.

[0043] The connecting portion 452 extends along the second direction Y and is fixedly connected to the side of the insertion block 451. The fixing method can be welding or bolt connection. The height of the connecting portion 452 in the first direction X is less than the height of the second connecting hole 421 in the first direction X, so that the connecting portion 452 can slide relative to the pressing block 420 in the first direction X. The connecting post 453 is provided on the top wall of the connecting portion 452 and extends vertically. A connecting hole 422 is opened in the hole wall of the second connecting hole 421. The top wall of the connecting post 453 extends into the connecting hole 422. The depth of the connecting hole 422 is greater than the height of the connecting post 453 to ensure sufficient sliding clearance 423.

[0044] With the insertion part 450, when the fixing post 300 is inserted and fixed, when the pressing block 420 slides down in the first direction X, the wall of the connecting hole 422 will squeeze the elastic member 440. Since the connecting part 452 is fixedly connected to the insertion part 450, it cannot slide in the first direction X. Therefore, the elastic member 440 will be compressed and deformed in the first direction X. At the same time, the connecting post 453 will also be inserted into the connecting hole 422.

[0045] After the connecting post 453 is inserted into the connecting hole 422, when the pressing block 420 slides in the second direction Y, the hole wall of the connecting hole 422 is pressed against the side of the connecting post 453, thereby causing the connecting part 452 to slide in the second direction Y, and then causing the plug-in block 451 to slide synchronously, so as to realize that the plug-in block 451 is inserted into the fixing post 300 or separated from the fixing post 300.

[0046] In some embodiments of this application, the fixing structure supporting the main body device 500 further includes a limiting block 510. The limiting block 510 is disposed on the bottom wall of the main body device 500 and is inserted into the first limiting groove 110; wherein, the first limiting groove 110 has a plurality of buffer protrusions 120, and the buffer protrusions 120 abut against the limiting block 510.

[0047] Specifically, the buffer protrusion 120 can be made of rubber and inserted into the first limiting groove 110 by the limiting block 510, which can effectively achieve a stable connection between the main equipment 500 and the fixed plate 100. The buffer protrusion 120 can further improve the stability of the main equipment 500 and reduce the possibility of vibration being transmitted to the main equipment 500 through the fixed part and the limiting block 510.

[0048] Exemplary transmission line diagnostic device

[0049] The transmission line diagnostic device includes a main unit 500 and a supporting structure for the main unit as described in any of the above embodiments. The fixing plate 100 of the supporting structure is configured to support the main unit 500. The main unit 500 is a diagnostic device.

[0050] Specifically, the diagnostic equipment can be a diagnostic instrument or other equipment capable of diagnosing cables.

[0051] The transmission line diagnostic device provided in this application utilizes a support structure to quickly fix and install the main equipment 500, thereby improving overall installation efficiency and accelerating the work progress.

[0052] Figure 4 The diagram shown is a side view of the sliding block and slide rail in some embodiments of this application. (Refer to...) Figure 1 and Figure 4As shown, in some embodiments of this application, the power transmission line diagnostic device further includes: a sliding block 130, a slide rail 140, a drive member 150, a transmission mechanism 800, and a guide mechanism 900. The sliding block 130 is fixed to the fixed plate 100 and has a sliding groove 131. The slide rail 140 passes through the sliding groove 131 and extends in the first direction X. The drive member 150 is fixed to the sliding block 130 and has a power output end. The transmission mechanism 800 is connected to the power output end and the slide rail 140, allowing the sliding block 130 to slide along the slide rail 140. The guide mechanism 900 is connected to the slide rail 140 and the sliding groove 131. Due to the influence of gravity, the guide mechanism 900 is provided to prevent collisions during the process of the transmission mechanism 800 cooperating with the slide rail 140 to drive the sliding block 130 upwards, ensuring that the sliding block 130 can rise or fall in the first direction X.

[0053] Specifically, the slide rail 140 can be a cylindrical structure with a rectangular cross-section, and the sliding groove 131 can be a rectangular groove that can cooperate with the slide rail 140, thereby restricting the circumferential rotation of the sliding block 130. The side of the sliding block 130 is directly welded to the side of the fixed plate 100, and the driving component 150 is fixed to the top wall of the sliding block 130. A through hole is opened on the top wall of the sliding block 130 for the transmission mechanism 800 to pass through, and the transmission mechanism 800 is connected to the slide rail 140 through the through hole.

[0054] By setting up the sliding block 130 and the slide rail 140, when it is necessary to raise the diagnostic equipment to a specified height, the slide rail 140 is first fixed, and then the drive component 150 is activated. The drive component 150 drives the transmission mechanism 800 to operate. The transmission mechanism 800 cooperates with the slide rail 140 to allow the sliding block 130 to slide on the slide rail 140, thereby driving the fixed plate 100 to rise. It should be understood that the drive component 150 can be a drive motor, and the transmission mechanism 800 can be a gear 810 and a rack 820, or a sprocket and a chain. The specific composition of the transmission mechanism 800 can be selected according to the actual situation on site.

[0055] In some embodiments of this application, the transmission mechanism 800 includes a gear 810, a rack 820, and a protective cover 830. The gear 810 is connected to the power output end. The rack 820 is disposed on the slide rail 140 and distributed along the extension direction of the slide rail 140, and the gear 810 meshes with the rack 820. The protective cover 830 is fixed to the sliding block 130 and covers the gear 810.

[0056] Specifically, gear 810 is connected to the power output end of drive member 150 via a coupling, and one side of gear 810 passes through sliding block 130 to mesh with rack 820. A long groove extending through in the first direction X is formed on one side of slide rail 140, and rack 820 is connected to the bottom wall of the long groove along the first direction X. Gear 810 partially extends into the long groove, which serves to limit its movement. When drive member 150 outputs power, gear 810 rotates, meshing with rack 820, allowing it to rise or fall along rack 820. Since gear 810 is connected to sliding block 130 via drive member 150, sliding block 130 can move along the extension direction of slide rail 140. Protective cover 830 protects gear 810, reducing the possibility of environmental debris contacting and damaging gear 810.

[0057] In some embodiments of this application, the guiding mechanism 900 includes a guide block 910. The guide block 910 is disposed on the side wall of the sliding groove 131. The slide rail 140 has a guide groove 920 along a first direction X on one side for the guide block 910 to slide. Multiple balls 930 are rolledly connected to the side wall of the guide groove 920, and the balls 930 are rolledly connected to the side of the guide block 910. The guide groove 920 and the long groove are respectively disposed on opposite sides of the slide rail 140, enabling the guiding mechanism to provide better guidance. By providing the guide block 910, the guide block 910 and the guide groove 920 cooperate to generate a guiding effect, ensuring the stability of the sliding block 130 during its ascent or descent. Furthermore, by providing the balls 930, the frictional force during the sliding of the guide block 910 can be reduced, effectively realizing the guiding effect of the guide block 910 and the guide groove 920 on the sliding block 130.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
