Description

Technical Field

[0001] This utility model relates to the field of power system infrastructure construction technology, and in particular to a positioning and calibration device for modular installation of 220kV smart substations. Background Technology

[0002] Chinese patent CN202421051846.3 discloses a positioning and installation detection device for power system infrastructure construction. It can obtain high-precision information by measuring the depth of the foundation pit and the angles on both sides without moving the device for positioning, saving the time of positioning and moving the device and improving the detection efficiency. However, it has some shortcomings in practical applications. It mainly relies on a tracked structure for movement. When it needs to be transported over a long distance in a substation or moved on relatively flat ground, its movement speed is slow and the operation is inconvenient, which affects the work efficiency. Moreover, the storage and fixing methods of core components such as detection modules are not well considered. When transporting over short distances, modular disassembly and assembly is time-consuming. The detection modules may need to be disassembled in a complicated way or may not be effectively fixed and protected, which poses a risk of cumbersome operation and accidental damage.

[0003] Therefore, this application provides a positioning and calibration device for modular installation in 220kV smart substations to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a positioning and calibration device for modular installation in 220kV smart substations. It aims to solve the problems of slow movement speed and inconvenient operation when the device needs to be transported over long distances within the substation or moved on relatively flat ground, which affects work efficiency. Furthermore, the device does not adequately consider the storage and fixing methods of core components such as detection modules. When transporting over short distances, modular disassembly and assembly is time-consuming. Detection modules may require complex disassembly or cannot be effectively fixed and protected, resulting in cumbersome operation and the risk of accidental damage.

[0005] To achieve the above objectives, this application provides the following technical solution: a positioning calibration device for modular installation in a 220kV smart substation, comprising a calibration device body, the calibration device body further comprising a vehicle body and a detection module, the detection module sliding above the vehicle body, the vehicle body having a first observation hole and a second observation hole adapted to the detection module, tracks connected to the bottom of both the left and right sides of the vehicle body, a handrail connected to the front end of the vehicle body, a traveling wheel connected to the rear end of the vehicle body, an elastic telescopic block for limiting the detection module provided on the vehicle body above the traveling wheel, and a lead screw and a guide rod connected to the vehicle body for the forward and backward sliding of the detection module, the lead screw being located on the left side of the detection module, and the guide rod being located on the right side of the detection module;

[0006] The top of the detection module is connected to a handle. The first observation hole is connected to the side wall of the second observation hole. The other side wall of the second observation hole is provided with a placement groove that is adapted to the handle. The vehicle body is also provided with a drive motor for driving the lead screw to rotate.

[0007] The front outer wall of the vehicle body is provided with a guide groove for installing a protective plate. By combining the tracks, wheels and handrails, and integrating the sliding, limiting and storage structure of the detection module, the device achieves the overall beneficial effects of flexible movement, accurate detection and positioning, and convenient and stable module storage, effectively improving the calibration efficiency and equipment protection of the modular installation of substations.

[0008] Preferably, the left and right sides of the detection module are respectively connected to a connecting slider and a guide slider via a rotating shaft. The connecting slider has a threaded hole that matches the lead screw. The guide slider slides on the guide rod. Through the precise transmission of the lead screw and the stable guidance of the guide rod, the smoothness and positioning accuracy of the front and back sliding of the detection module are ensured.

[0009] Preferably, a mounting block is provided above the vehicle body, and multiple sets of mounting blocks are provided. The two ends of the guide rod are mounted on the vehicle body through the mounting blocks. The front end of the lead screw is fixed to the vehicle body through the drive motor, and the rear end of the lead screw is fixed to the vehicle body through the mounting blocks.

[0010] Preferably, the placement slot is further provided with a winding strap for storing the detection module, and the elastic telescopic block is connected with a buckle that is compatible with the winding strap. By using the winding strap and the buckle in cooperation, the detection module can be easily fixed in the placement slot, which enhances the stability in the storage state and avoids accidental shaking.

[0011] Preferably, the vehicle body is provided with a winding spring for automatically winding the winding strap. The winding spring enables automatic retraction of the strap, simplifies the storage operation, and improves the convenience of use.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, the handrails and wheels provide a faster and more convenient way to move on flat or longer routes while retaining the ability of the tracks to adapt to complex terrain. This significantly improves the flexibility and efficiency of the device's transportation and solves the problem of inconvenient movement of existing devices.

[0014] In this invention, by setting up a structure that facilitates the storage and fixation of the detection module, including rotation positioning, placement slots, winding straps and buckles, the detection module can be easily, quickly and securely stored and protected during transportation or when not in operation, without complicated disassembly and assembly. This improves the ease of operation and reduces the risk of module damage, solving the problems of inconvenient storage and insufficient fixation and protection of the detection module in existing devices.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] refer to Figure 1-4The positioning and calibration device shown is used for modular installation of a 220kV smart substation. It includes a calibration device body 1, a vehicle body 2, and a detection module 13. The detection module 13 slides above the vehicle body 2. The vehicle body 2 has a first observation hole 19 and a second observation hole 20 adapted to the detection module 13. Tracks 4 are connected to the bottom of both sides of the vehicle body 2. In order to facilitate the transportation of the calibration device body 1 in complex terrain, a handrail 3 is connected to the front end of the vehicle body 2, and a traveling wheel 5 is connected to the rear end of the vehicle body 2. An elastic telescopic block 15 for limiting the detection module 13 is provided on the vehicle body 2 above the traveling wheel 5. This allows the vehicle body 2 to move easily by pulling the handrail 3 and using the traveling wheel 5 when it encounters long-distance movement, without the need to use the tracks 4 for slow movement. The front outer wall of the vehicle body 2 has a guide groove 22 for installing a protective plate 18.

[0023] As one implementation method in this embodiment, in order to facilitate the detection module 13 to perform detection, the vehicle body 2 is also connected to a lead screw 8 and a guide rod 9 for the detection module 13 to slide back and forth. The lead screw 8 is located on the left side of the detection module 13, and the guide rod 9 is located on the right side of the detection module 13. The vehicle body 2 is also provided with a drive motor 7 for driving the lead screw 8 to rotate. The upper part of the vehicle body 2 is provided with a mounting block 6, which has three sets. The two ends of the guide rod 9 are mounted on the vehicle body 2 through the mounting block 6. The front end of the lead screw 8 is fixed to the vehicle body 2 through the drive motor 7, and the rear end of the lead screw 8 is fixed to the vehicle body 2 through the mounting block 6. The left and right sides of the detection module 13 are respectively connected to a connecting slider 10 and a guide slider 12 through a rotating shaft 11. The connecting slider 10 has a threaded hole that matches the lead screw 8, so that the device housing drives the lead screw 8 to rotate through the drive motor 7, and drives the detection module 13 to slide back and forth on the lead screw 8 and the guide rod 9 through the slider connecting slider 10.

[0024] As one implementation method in this embodiment, in order to allow the detection module 13 to be stored without complete disassembly, the guide slider 12 slides on the guide rod 9, the top of the detection module 13 is connected to the handle 14, the first observation hole 19 is connected to the side wall of the second observation hole 20, and the other side wall of the second observation hole 20 is provided with a placement groove 21 adapted to the handle 14. The placement groove 21 is also provided with a winding strap 17 for storing the detection module 13. The elastic telescopic block 15 is connected with a buckle 16 adapted to the winding strap 17. The vehicle body 2 is provided with a winding spring for automatically winding the winding strap 17, so that when the detection module 13 is stored in the second observation hole 20, it can be pulled out by the winding strap 17, pass through the handle 14 on the detection module 13, and then connect with the buckle 16 to achieve the effect of auxiliary fixation of the detection module 13.

[0025] The working principle of this device is as follows: When in use, the operator first pulls the calibration device body 1 through the handle 3 and moves it through the walking wheels 5 connected to the rear end of its vehicle body 2. After moving it to the working position, the operator first pulls the protective plate 18 at the bottom of the vehicle body 2 out of the guide groove 22, and then separates the winding strap 17 from the buckle 16, so that the winding strap 17 automatically retracts into the vehicle body 2. The operator then manually presses the elastic telescopic block 15 to prevent it from pressing against the detection module 13. Then, the operator pulls the detection module 13 through the handle 14, so that the detection module 13 rotates around the pivot 11, rotating the detection module 13 90 degrees. After that, the detection module 13 can be used for detection and calibration. At the same time, the drive motor 7 drives the lead screw 8 to rotate, and the slider connected to the slider 10 drives the detection module 13 to slide back and forth on the lead screw 8 and the guide rod 9, so that the detection module 13 can achieve better detection results.
