Description

Technical Field

[0001] The utility model relates to the technical field of relay protection, in particular to a training device. Background Art

[0002] Relay protection detects faults or abnormal conditions in the power system and sends out alarm signals. In university practical training classes, teachers need to explain relay protection devices. When explaining relay protection devices, teachers usually place the relay protection devices on the training table to show them to students.

[0003] In the prior art, there is a training platform for a relay protection device with patent number CN215770212U, which includes a box body and an operation panel, wherein a rectangular opening is provided in the operation panel, and the front and rear inner walls of the rectangular opening are overlapped with the front and rear sides of the U-shaped plate respectively. The utility model flips the fixed plate so that the relay protection device body is on the upper side of the operation panel, thereby displaying the relay protection device body, and then moves the clamping rod 2 upward through the handle 2 to insert the clamping rod 2 into the sliding sleeve 1. The clamping rod 1 can restrict the clamping rod 2 by cooperating with the clamping hole. However, the training platform for a relay protection device in the prior art cannot increase the contact area between the training platform and the desktop or the ground during use, so that the smaller contact area easily causes the training platform to tilt and be unstable. For this reason, a training device is proposed. Utility Model Content

[0004] In view of this, the embodiment of the utility model hopes to provide a training device to solve or alleviate the technical problems existing in the prior art. By installing a supporting assembly, the contact area between the device and the ground can be increased. Because the contact area between the device and the ground is increased, the device can be more stable when used, making it less likely for the device to tip over during use.

[0005] The technical solution of the utility model embodiment is achieved as follows:

[0006] A training device comprises a base assembly, four support assemblies and a shell assembly are rotatably arranged on the base assembly, a relay protection body is fixedly installed inside the shell assembly, a threaded rod is rotatably arranged on the base assembly, a sliding block is threadedly arranged at one end of the threaded rod, a rotating square rod rotatably arranged with the shell assembly is rotatably arranged on the sliding block, the support assembly comprises a first support bar, a second support bar rotatably arranged inside the first support bar, and two limit assemblies corresponding to the four support assemblies are rotatably arranged on the base assembly.

[0007] Preferably: the base assembly includes a U-shaped base, two side panels fixedly installed on the lower surface of both ends of the base, and four fixed blocks fixedly installed on the lower surface of the U-shaped base. The installation of the side panels can limit the first support bar, so that the first support bar stops rotating after it rotates into place.

[0008] Preferably: a first torsion spring is fixedly installed between the four first support bars and the four fixed blocks, a second torsion spring is fixedly installed between the four first support bars and the four second support bars, the rotation angle between the four first support bars and the four second support bars is greater than 90°, and the ends of the four first support bars away from each other are provided with limiting ends for limiting the second support bars. The installation of the first torsion spring and the second torsion spring can push the first support bar and the second support bar to rotate and unfold, so that the first support bar and the second support bar can be automatically unfolded, making the unfolding of the device more convenient.

[0009] Preferably: the limiting assembly includes a rotating frame, two arc-shaped pieces fixedly mounted at both ends of the top of the rotating frame, the two first support bars are each provided with an arc-shaped groove arranged to cooperate with the arc-shaped piece for rotation, a handle is fixedly mounted on one side of the U-shaped base, and a damping cooperation is arranged between the limiting assembly and the base assembly. The bottom of the rotating frame can limit the second support bar after rotation and contraction, so that the second support bar is not easy to automatically unfold after rotation and contraction.

[0010] Preferably, the housing assembly comprises a rotating shell and a cover plate fixedly mounted on one side of the rotating shell, and both ends of the rotating shell are rotatably arranged on the top of the U-shaped base. The installation of the cover plate can seal the bottom of the relay protection body.

[0011] Preferably: a handwheel is fixedly installed on one side of the threaded rod and is rotatably matched with the U-shaped base. A guide groove is opened inside the U-shaped base, and the sliding block is slidably matched in the guide groove. The opening of the guide groove can guide the sliding block during the sliding process, so that the sliding block can slide more smoothly.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model can increase the contact area between the device and the ground by installing the support assembly. Because the contact area between the device and the ground is increased, the device is more stable when used, making it less likely for the device to topple over during use.

[0014] Second, the utility model can drive the relay protection body to rotate and then tilt through the installation of the threaded rod, so that the tilted relay protection body is easier for trainees to watch, thereby making the relay protection body easier for trainees to observe.

DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, an embodiment of the utility model provides a training device, including: a base assembly 1, four support assemblies 2 and a shell assembly 3 are rotatably arranged on the base assembly 1, a relay protection body 4 is fixedly installed inside the shell assembly 3, a threaded rod 5 is rotatably arranged on the base assembly 1, a sliding block 6 is threadedly arranged at one end of the threaded rod 5, a rotating square rod 7 rotatably arranged with the shell assembly 3 is rotatably arranged on the sliding block 6, the support assembly 2 includes a first support bar 8, a second support bar 9 rotatably arranged inside the first support bar 8, and two limit assemblies 10 corresponding to the four support assemblies 2 are rotatably arranged on the base assembly 1.

[0026] In this embodiment, specifically: the base assembly 1 includes a U-shaped base 11, two side plates 12 fixedly installed on the lower surface of both ends of the base 11, and four fixed blocks 13 fixedly installed on the lower surface of the U-shaped base 11. A first torsion spring 14 is fixedly installed between the four first support bars 8 and the four fixed blocks 13, and a second torsion spring 15 is fixedly installed between the four first support bars 8 and the four second support bars 9. The rotation angle between the four first support bars 8 and the four second support bars 9 is greater than 90°, and the ends of the four first support bars 8 that are away from each other are each provided with a limiting end 801 for limiting the second support bar 9. When the first support bar 8 and the second support bar 9 need to be rotated and unfolded, the limiting assembly 10 is rotated at this time. The rotating limiting assembly 10 no longer continues to limit the first support bar 8 and the second support bar 9. Under the push of the first torsion spring 14 and the second torsion spring 15, the first support bar 8 and the second support bar 9 are unfolded at this time.

[0027] In this embodiment, specifically: the limit assembly 10 includes a rotating frame 16, two arc-shaped pieces 17 fixedly installed at both ends of the top of the rotating frame 16, and the ends of the two first support bars 8 close to each other are each provided with an arc-shaped groove 802 that is rotatably matched with the arc-shaped piece 17. A handle 18 is fixedly installed on one side of the U-shaped base 11. The limit assembly 10 and the base assembly 1 are provided with a damping match. The setting of the handle 18 makes it easy to carry the device.

[0028] In this embodiment, specifically: the housing assembly 3 includes a rotating shell 19 and a cover plate 20 fixedly mounted on one side of the rotating shell 19. Both ends of the rotating shell 19 are rotatably arranged on the top of the U-shaped base 11. The installation of the rotating shell 19 facilitates the tilting of the relay protection body 4.

[0029] In this embodiment, specifically: a handwheel 21 is fixedly installed on one side of the threaded rod 5 and is rotatably matched with the U-shaped base 11. A guide groove is opened inside the U-shaped base 11, and the sliding block 6 is slidably matched in the guide groove. The installation of the handwheel 21 facilitates the threaded rod 5 to rotate.

[0030] When the utility model is working: when the support assembly 2 needs to be unfolded to increase the contact area between the device and the ground, the limiting assembly 10 is rotated at this time, and the limiting assembly 10 no longer continues to limit the first support bar 8 after rotation, and the first support bar 8 is rotated at this time, and the first support bar 8 is unfolded after rotation, and then the second support bar 9 is rotated, and the second support bar 9 is unfolded after rotation, then the contact area between the device and the ground at this time is increased from the size of the lower surface of the base assembly 1 to the size of the area between the four second support bars 9, and the contact area between the device and the ground at this time is increased, so that the device is more stable when used and is not easy to tip over;

[0031] When the relay protection body 4 needs to be tilted, because the lecturer usually stands on the podium to demonstrate, and the students usually sit on the bench to watch the demonstration, because the students' eyes are in an upward state, because the relay protection body 4 needs to be tilted, so as to make it easier for the students to watch the demonstration, then the threaded rod 5 is rotated at this time, the rotation of the threaded rod 5 drives the sliding block 6 to slide, the sliding of the sliding block 6 drives the rotating square rod 7 to rotate, and the rotation of the rotating square rod 7 drives the housing assembly 3 and the relay protection body 4 to tilt, such as Figure 1 As shown, the relay protection body 4 is in a tilted state at this time.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
