Description

Technical Field

[0001] This utility model relates to the technical field of seismic testing devices, specifically a seismic testing device for an ultra-high voltage DC bypass switch. Background Technology

[0002] Ultra-high voltage direct current bypass switch is a mechanical power switching device that is connected between the DC terminals of one or more converter stations. It short-circuits the converter bridge when it is out of operation and transfers the current to the converter valve when it is put into operation.

[0003] Currently, after the production of UHVDC bypass switches, it is generally necessary to conduct seismic resistance tests. However, the surface of current UHVDC bypass switches typically has many electronic components. When fixing them on a seismic resistance test platform, the clamping method can easily damage these electronic components. Furthermore, current UHVDC bypass switches generally have feet installed on both sides (for fixing the UHVDC bypass switch during subsequent use). Therefore, a new type of UHVDC bypass switch seismic testing device is needed to solve the above problems by utilizing the existing appearance characteristics of UHVDC bypass switches. Utility Model Content

[0004] The purpose of this invention is to address the problem that the surface of current ultra-high voltage DC bypass switches is generally equipped with many electronic components, and these electronic components are easily damaged when the switch is fixed on a seismic testing platform by clamping. This invention provides a seismic testing device.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A seismic testing device includes: a mounting frame, a vibration frame disposed above the mounting frame, and a vibration unit for vibrating the vibration frame;

[0007] The vibrating frame is provided with an ultra-high voltage DC bypass switch body and two drive plates above it, and also includes a first drive unit. The first drive unit is used to install the two drive plates above the vibrating frame and control them to move closer or further apart from each other.

[0008] Two sliders are slidably inserted into the surface of the corner seats on both sides of the ultra-high voltage DC bypass switch body. Several sliders are slidably inserted into the surface of the two drive plates respectively. The switch also includes a second drive unit, which is used to drive several sliders to slide on the inner wall of the two drive plates respectively.

[0009] Furthermore, the vibration unit includes several guide rods that are fixedly mounted on the surface of the mounting frame. Each guide rod has a vibration spring slidably sleeved on its surface. Both ends of each vibration spring are fixedly mounted on the surface of the vibration frame and the mounting frame, respectively. A vibration motor is fixedly mounted on the surface of the vibration frame, and the vibration motor is electrically connected to a controller fixedly mounted on the surface of the mounting frame.

[0010] Furthermore, the first drive unit includes two drive slots, each opened on the top of the vibration frame, and positive and negative threaded screws. The surfaces of the two drive plates are slidably inserted into the inner walls of the two drive slots, and the surfaces of the positive and negative threaded screws are rotatably inserted into the inner walls of the two drive slots. Both drive plates are threaded onto the surfaces of the positive and negative threaded screws.

[0011] Furthermore, the second drive unit includes several U-shaped frames that are respectively fixedly installed on the top of the two drive plates. Each of the U-shaped frames has a drive threaded rod threaded into its surface, and one end of each drive threaded rod is rotatably inserted into the surface of a number of sliders.

[0012] Furthermore, two telescopic tubes are provided above each of the two drive boards, and a connecting unit is also included. The connecting unit is used to install a plurality of the telescopic tubes onto the surface of the two drive boards respectively.

[0013] Furthermore, the two telescopic tubes include several hollow tubes, one end of each hollow tube is threaded with an extension tube, and the surface of each extension tube is provided with abutment protrusions.

[0014] Furthermore, the connection unit includes several mounting tubes that are respectively fixedly installed on the top of the two drive plates. One end of each of the several empty tubes is provided with an external thread protrusion, and the surface of each of the several external thread protrusions is threaded into one end of the several mounting tubes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a vibration frame is set above the mounting bracket. During use, the user first places the UHVDC bypass switch body on the vibration frame, and then controls the distance between the two drive plates through the first drive unit, so that the two drive plates are respectively set above the feet on both sides of the UHVDC bypass switch body. Then, the second drive unit drives several sliders to slide on the inner wall of the two drive plates, so that the sliders slide into the surface of the feet on both sides of the UHVDC bypass switch body (the surface of the feet has reserved holes). This installation method can be used to install the UHVDC bypass switch body by utilizing the structure of the UHVDC bypass switch body itself, or it can simulate the installation method of the UHVDC bypass switch body in real-world situations (the existing UHVDC bypass switch body is installed on the mounting platform through the corner seats on both sides), making the experimental results more accurate.

[0017] 2. In this utility model, by installing two telescopic tubes above each of the two drive plates via a connecting unit, when in use, after the user installs the UHVDC bypass switch body above the vibration unit, several telescopic tubes are respectively installed above the two drive plates via the connecting unit. By adjusting the length of several telescopic tubes, several abutting protrusions abut against the surfaces of the two iron handles respectively set on both sides of the UHVDC bypass switch body, further limiting the position of the UHVDC bypass switch body.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] This embodiment provides a seismic testing device for ultra-high voltage DC bypass switches, mainly to address the problem that current ultra-high voltage DC bypass switches generally have many electronic components on their surface, and these components are easily damaged when the switch is fixed on a seismic testing platform using clamping methods. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0026] A seismic testing device for an ultra-high voltage direct current (UHVDC) bypass switch includes: a mounting frame 1 with a vibration frame 2 mounted on top, and two drive plates 5 mounted on top of the vibration frame 2. In use, the user first places the UHVDC bypass switch body 4 on the surface of the vibration frame 2. A first drive unit 6 controls the distance between the two drive plates 5 mounted on the vibration frame 2, ensuring that the corner supports on both sides of the UHVDC bypass switch body 4 are positioned below the two drive plates 5. Then, a second drive unit 8 drives several sliders 7, which are slidably inserted into the surfaces of the two drive plates 5, to move, such that if... The sliders 7 are slidably inserted into the surfaces of the corner seats on both sides of the UHVDC bypass switch body 4 (the surfaces of the corner seats are all provided with reserved holes), which can limit the position of the UHVDC bypass switch body 4 above the vibration frame 2. Finally, the vibration frame 2 is vibrated by the vibration unit 3 to achieve the vibration resistance test of the UHVDC bypass switch body 4. The main components of the vibration unit 3 are: several vibration springs 32 with both ends fixedly installed on the surfaces of the vibration frame 2 and the mounting frame 1, and several guide rods 31 are fixedly installed on the surface of the mounting frame 1. The vibration springs 32 are respectively slidably sleeved. Connected to the surface of several guide rods 31, during use, the user drives the vibration motor 33, which is fixedly installed on the surface of the vibration frame 2, through the controller 34 fixedly installed on the surface of the vibration frame 2, thereby driving the vibration frame 2 to rotate and realize the vibration detection of the UHVDC bypass switch body 4 above the vibration frame 2. The main components of the first drive unit 6 are: two drive slots 61, both opened on the top of the vibration frame 2, and positive and negative threaded screws 62. At the same time, one end of the positive and negative threaded screws 62 is sequentially rotatably inserted into the inner wall of one drive slot 61, the surface of one drive plate 5, and the other drive slot 61. The inner wall of drive plate 1 and the surface of another drive plate 5 are such that when the user rotates the positive and negative threaded screws 62, the two drive plates 5 can slide on the inner walls of the two drive slots 61 respectively, that is, the two drive plates 5 move closer or further apart from each other. The main components of the second drive unit 8 are: two drive threaded rods 82, and two U-shaped frames 81 are fixedly installed on the top of the two drive plates 5. When in use, the user rotates several drive threaded rods 82 respectively, which can drive several sliders 7 that are respectively rotated and sleeved on the surface of the two drive threaded rods 82 to slide on the surface of the two drive plates 5.

[0027] By setting a vibration frame 2 above the mounting frame 1, the user first places the UHVDC bypass switch body 4 on the vibration frame 2, and then controls the distance between the two drive plates 5 through the first drive unit 6, so that the two drive plates 5 are respectively positioned above the feet on both sides of the UHVDC bypass switch body 4. Then, the second drive unit 8 drives several sliders 7 to slide on the inner wall of the two drive plates 5, so that the sliders 7 slide into the surface of the feet on both sides of the UHVDC bypass switch body 4 (the surface of the feet has reserved holes). This installation method can be used to install the UHVDC bypass switch body 4 by utilizing the structure of the UHVDC bypass switch body 4 itself, or it can simulate the installation method of the UHVDC bypass switch body 4 in real-world situations (the existing UHVDC bypass switch body 4 is installed on the mounting platform through the corner seats on both sides), making the experimental results more accurate.

[0028] By installing two telescopic tubes 9 above each of the two drive plates 5 via the connecting unit 10, when in use, after the user installs the UHVDC bypass switch body 4 above the vibration unit 3, several telescopic tubes 9 are respectively installed above the two drive plates 5 via the connecting unit 10. By adjusting the length of several telescopic tubes 9, several abutting protrusions 93 abut against the surfaces of the two iron handles respectively set on both sides of the UHVDC bypass switch body 4, further limiting the position of the UHVDC bypass switch body 4 can be achieved.

[0029] like Figure 1 and Figure 4As shown, in some embodiments, two telescopic tubes 9 are provided above each of the two drive plates 5. During use, the user needs to install several telescopic tubes 9 onto the surfaces of the two drive plates 5 via the connecting unit 10, and then place the surfaces of the several telescopic tubes 9 against the surfaces of the iron handles on both sides of the UHVDC bypass switch body 4. This further limits the position of the UHVDC bypass switch body 4 above the vibration frame 2. The main components of the two telescopic tubes 9 are several empty tubes 91. The user can control the length of the several telescopic tubes 9 by rotating several extension tubes 92, which are threaded into one end of each of the empty tubes 91. Each of the extension tubes 92 has abutment protrusions 93 on its surface. Therefore, during use, the abutment protrusions 93 can abut against the iron handles on both sides of the UHVDC bypass switch body 4 to ensure the limiting effect on the UHVDC bypass switch body 4. The main components of the connecting unit 10 are: a few external thread protrusions 102 respectively set at one end of a few empty tubes 91, and two mounting tubes 101 are fixedly installed on the top of the two drive plates 5. During use, the user can thread the surfaces of the abutment protrusions 102 into the inner walls of the mounting tubes 101 to install the abutment tubes 9 above the two drive plates 5.

[0030] The working process of this utility model:

[0031] First, the user needs to place the UHVDC bypass switch body 4 on the vibration frame 2, rotate the positive and negative threaded screws 62 so that the two drive plates 5 are respectively positioned above the feet on both sides of the UHVDC bypass switch body 4, and then rotate several drive threaded rods 82 so that several sliders 7 are respectively slid into the surface of the feet on both sides of the UHVDC bypass switch body 4, thereby achieving the initial positioning of the UHVDC bypass switch body 4 above the vibration frame 2;

[0032] Secondly, the user needs to insert several external threaded protrusions 102 into the inner walls of several mounting tubes 101 respectively, so that several extension tubes 92 and several abutting protrusions 93 respectively abut against the surfaces of two iron handles respectively provided on both sides of the UHVDC bypass switch body 4 (the existing UHVDC bypass switch body 4 is provided with iron handles on both sides), thus completing the stable positioning of the UHVDC bypass switch body 4.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
