[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, referring to Figures 1 to 5, is the first embodiment of the present invention. This embodiment provides a secondary pressure plate device for power system relay protection, which can achieve a high safety effect for the secondary pressure plate. It includes a protection component 100, which includes a main body assembly 101 and a rotating assembly 102 fixedly mounted on the main body assembly 101. It also includes a track assembly 103 slidably mounted on the outer wall of the rotating assembly 102, the track assembly 103 being connected to the main body assembly 101, and a temporary assembly 104 fixedly mounted on the rotating assembly 102. The main body assembly 101 can protect the secondary pressure plate internally, thereby... To prevent the risk of secondary pressure plate being subjected to force collision or accidental contact, if it is necessary to put or take off the secondary equipment, after opening the main component 101, the temporary component 104 is pulled upward to release the limit between the temporary component 104 and the track component 103. At this time, by pushing the temporary component 104, the rotating component 102 is moved. The rotating component 102 can adjust the putting or taking off of the secondary equipment. In both the putting and taking off states of the secondary equipment, there is a limit function between the temporary component 104 and the track component 103, which makes the putting or taking off of the secondary equipment extremely stable and avoids the problem of inaccurate putting or taking off of the secondary equipment.

[0029] The reinforcing component 200 includes a spring component 201 fixedly disposed on the main body assembly 101, and a snap-fit ​​component 202 disposed on the spring component 201. The snap-fit ​​component 202 is adapted to the rotating component 102. It also includes a limiting component 203 adapted to the snap-fit ​​component 202, a prompting component 204 fixedly disposed on the limiting component 203, and the prompting component 204 connected to the main body assembly 101. Furthermore, it includes a pressing component 205 adapted to the prompting component 204, and the pressing component 205 connected to the main body assembly 101. After the main body assembly 101 is opened, it can be... The prompting component 204 indicates the operating method to the user. When it is necessary to put in or take out the secondary equipment, by pulling the prompting component 204, the limit between it and the squeezing component 205 is released. At the same time, the prompting component 204 will drive the limit component 203 to move, thereby releasing the limit between the limit component 203 and the locking component 202. At this time, when the rotating component 102 is moved, it will squeeze the locking component 202, and the locking component 202 will squeeze the elastic component 201, so that when the rotating component 102 is moved, there is a clicking sound, thereby informing the user of the progress of putting in or taking out the secondary equipment.

[0030] During use, the main component 101 protects the secondary pressure plate internally, preventing the risk of impact or accidental contact. To engage or disengage the secondary equipment, after opening the main component 101, pull upwards the temporary component 104 to release its limit on the track component 103. Then, pushing the temporary component 104 moves the rotating component 102, which adjusts the engagement and disengagement of the secondary equipment. Both the temporary component 104 and the track component 103 have limit functions, ensuring stability during engagement and disengagement and preventing inaccuracies. After opening the main component 101, the prompt component 204 provides a prompt for activation. Using a manual operation method, when it is necessary to put on or take off the secondary equipment, the prompt component 204 is pulled to release the limit between it and the squeezing component 205. At the same time, the prompt component 204 will drive the limit component 203 to move, thereby releasing the limit component 203 from the limit between it and the locking component 202. At this time, when the rotating component 102 is moved, it will squeeze the locking component 202, and the locking component 202 will squeeze the elastic component 201, so that when the rotating component 102 is moved, there is a clicking sound, thereby informing the user of the progress of putting on or taking off the secondary equipment.

[0031] In summary, when secondary equipment needs to be put in or taken out, the main component 101 provides protection. After the main component 101 is opened, the prompt component 204 and the limit component 203 can prompt the user with the correct putting in or taking out method. The temporary component 104 and the track component 103 enable the rotation component 102 to move the secondary equipment with a two-point limit function, which corresponds to the putting in and taking out points of the secondary equipment. Therefore, the operation is relatively safe and has good prompting and adjustment accuracy.

[0032] Example 2, referring to Figures 1-5, is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a protective component 100 for the secondary pressure plate device of the power system relay protection, solving the problem of unstable operation of the secondary pressure plate. It includes a main body assembly 101 comprising a protective base 101a and an electrically controlled lock 101b fixedly disposed on one side of the opening of the protective base 101a, a secondary pressure plate body 101c disposed inside the protective base 101a, and a protective device rotatably disposed on the protective base 101a. The cover 101d also includes a cable positioning seat 101e fixedly disposed on the other end of the protective base 101a at the electric lock 101b. During use, the electric lock 101b can lock the protective cover 101d, and the cable positioning seat 101e can fix the cable connected to the secondary pressure plate body 101c. When it is necessary to adjust the opening and closing of the secondary pressure plate body 101c, the limit between the electric lock 101b and the protective cover 101d is released by triggering the electric lock 101b. The secondary pressure plate body 101c can be adjusted after the protective cover 101d is opened.

[0033] Specifically, the rotating assembly 102 includes an open ring 102a, the center of which coincides with the rotation base point of the secondary pressure plate body 101c. The end of the open ring 102a is provided with a circular hole 102b, and the outer wall of the open ring 102a is provided with a toothed groove 102c. The opening of the open ring 102a is connected to the middle of the secondary pressure plate body 101c.

[0034] Furthermore, the track assembly 103 includes an arc-shaped shell 103a that slides on the outer wall of the open ring 102a. The top of the arc-shaped shell 103a has an opening 103b. The inner wall of the arc-shaped shell 103a has temporary grooves 103c on both sides of the opening 103b. The outer wall of the arc-shaped shell 103a has a reserved groove 103d in the middle of the temporary groove 103c. The top of the arc-shaped shell 103a has a semi-circular groove 103e at the top of the temporary groove 103c. The semi-circular groove 103e is adapted to the equipment shell 104a.

[0035] Furthermore, the provisional assembly 104 includes a device housing 104a fixedly disposed within the circular hole 102b, and a slider 104b slidably disposed within the device housing 104a. It also includes a ball bearing 104c disposed at the bottom of the slider 104b, the ball bearing 104c being adapted to the provisional groove 103c. Additionally, it includes a central rod 104d fixedly disposed at the top of the slider 104b, the central rod 104d being connected to the device housing 104a. Finally, it includes a first spring 104e fixedly disposed at the top of the slider 104b. The spring 104e is connected to the equipment housing 104a, and also includes a lifting plate 104f fixedly mounted on the top of the middle rod 104d. By pulling the lifting plate 104f, the middle rod 104d is moved, and the middle rod 104d drives the slider 104b and the ball bearing 104c into the equipment housing 104a, compressing the first spring 104e. When the lifting plate 104f is released, the first spring 104e rebounds, causing the slider 104b, the ball bearing, the middle rod 104d, and the lifting plate 104f to return to their original positions.

[0036] The rest of the structure is the same as in Example 1.

[0037] In use, by releasing the electric lock 101b and opening the protective cover 101d, the user can observe the prompt component 204. After reading the prompt component 204, the user can pull the prompt component 204 to disengage from the squeezing component 205 and move the limiting component 203. After the limiting component 203 moves, it will disengage from the limiting position between itself and the locking component 202. At this time, the lifting plate 104f can be pulled to move the middle rod 104d, the slider 104b, and the ball bearing 104c. At this time, the ball bearing 104c will disengage from the temporary groove 103c. Then, the equipment housing 104a can be pushed to move the opening ring 102a. The opening ring 102a can directly move the secondary pressure plate body 101c. When the secondary pressure plate body 101c moves from the insertion to the retraction state, the equipment shell 104a moves from the semicircular groove 103e at one end of the opening 103b to the semicircular groove 103e at the other end. At this time, the ball bearing 104c is also located at the top of the temporary groove 103c at the other end. At this time, the first spring 104e will drive the slider 104b and the ball bearing 104c into the temporary groove 103c for a second limit. During this process, the opening ring 102a will be subjected to the pressure of the elastic component 201 pressing the clamping component 202. As the opening ring 102a moves, the tooth groove 102c of the opening ring 102a will be pressed by the clamping component 202, resulting in a clicking sound, thus providing a high level of safety performance.

[0038] In summary, the secondary pressure plate body 101c is protected by the protective cover 101d during use, and the secondary pressure plate body 101c has two fixed points during the deployment and retraction process due to the cooperation between the temporary component 104 and the track component 103. Therefore, the secondary pressure plate body 101c has good deployment and retraction stability during use.

[0039] Example 3, referring to Figures 1-5, is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a reinforcing component 200 for the secondary pressure plate device of the power system relay protection, which solves the problem of accidental contact with the secondary pressure plate. It includes an elastic component 201, which includes a fixed base 201a fixedly disposed inside the protective base 101a. The fixed base 201a has an inner groove 201b inside, which has two spaces, an upper and a lower space, which are connected. The top of the fixed base 201a is provided with a slot 201c at the top of the end of the inner groove 201b, and a force-bearing block 201d slidably disposed at the bottom of the inner groove 201b. It also includes a second spring 201e fixedly disposed on the force-bearing block 201d, and the second spring 201e is connected to the fixed base 201a.

[0040] Specifically, the snap-fit ​​assembly 202 includes a transmission rod 202a slidably disposed on the top of the inner groove 201b. One end of the transmission rod 202a located inside the inner groove 201b has a first inclined surface 202b located at the slot 201c. The first inclined surface 202b is located at the slot 201c. A protruding rod 202c is fixedly disposed at the end of the transmission rod 202a. The end of the protruding rod 202c has a toothed end 202d. The toothed end 202d of the protruding rod 202c connects to the pre-reserved slot 103d and the toothed groove 102c. The toothed end 202d and the toothed groove 102c are adapted to each other. The transmission rod 202a is connected to the force-bearing block 201d.

[0041] Furthermore, the limiting component 203 includes a limiting plate 203a, the bottom of which is provided with a second inclined surface 203b, which is adapted to the first inclined surface 202b. After the second inclined surface 203b and the first inclined surface 202b are attached, the limiting plate 203a can limit the transmission rod 202a. The limiting plate 203a is adapted to the slot 201c.

[0042] Furthermore, the prompting component 204 includes a pressure plate 204a fixedly mounted on the top of the limiting plate 203a. The pressure plate 204a is connected to the protective seat 101a. The pressure plate 204a has a pull groove 204b and an indication groove 204c. The pull groove 204b is located at the end of the pressure plate 204a, and the indication groove 204c is located at the top center of the pressure plate 204a. The indication groove 204c contains text describing the usage of the secondary pressure plate body 101c. It also includes a fixing block 204d fixedly mounted on the top of the pressure plate 204a. The fixing block 204d is located at the top end of the pressure plate 204a. The fixing block 204d has a movable groove 204e, which is arc-shaped. It also includes a rubber block 204f fixedly mounted in the movable groove 204e. The device includes a movable plate 204g that slides within the movable groove 204e, and a rotating block 204h that is fixedly mounted at the end of the movable plate 204g. In the initial state, the rotating block 204h is pressed by the movable plate 204g and the rubber block 204f, causing the rotating block 204h to be initially tilted. Thus, when the protective cover 101d is closed, the rotating block 204h will immediately adhere to the protective cover 101d. As a result, when the protective cover 101d presses the rotating block 204h, it causes the movable plate 204g to press the rubber block 204f. The rotating block 204h is connected to the fixed block 204d, and the rotating block 204h and the fixed block 204d are rotatably connected. The top of the rotating block 204h is provided with an abutment surface 204i.

[0043] Furthermore, the extrusion assembly 205 includes a fixing strip 205a, which has a groove 205b, and a first flexible plate 205c fixedly disposed in the groove 205b. The first flexible plate 205c is arc-shaped, and there is a certain space between the top of its arc shape and the groove 205b. It also includes a second flexible plate 205d fixedly disposed at the end of the first flexible plate 205c. The second flexible plate 205d is also arc-shaped and is connected to the top of the first flexible plate 205c. The end of the second flexible plate 205d is connected to the fixing strip 205a.

[0044] The rest of the structure is the same as in Example 2.

[0045] When using the device, after opening the protective cover 101d, if the user needs to adjust the secondary pressure plate body 101c, the user should first check the indicator groove 204c on the pressure plate 204a to understand how to use the secondary equipment. Then, the user should insert their finger into the pull groove 204b and pull upwards to move the pressure plate 204a upwards. At this time, the end of the pressure plate 204a will press against the first flexible plate 205c, and the space between the top of the first flexible plate 205c and the groove 205b will be compressed. At this time, the second flexible plate 205d will also be compressed by the first flexible plate 205c. Deformation and compression cause the end of the pressure plate 204a to disengage from the extrusion assembly 205. Simultaneously, the pressure plate 204a drives the second inclined surface 203b of the limiting plate 203a to disengage from the first inclined surface 202b. At this point, the limiting position of the transmission rod 202a is released. As the open ring 102a moves, its tooth groove 102c presses against the tooth end 202d. The tooth end 202d presses against the protruding rod 202c, the transmission rod 202a, and the force block 201d. The force block 201d will press against the second spring 201e. At this time, there will be a gap between the tooth end 202d and the tooth groove 102c. The device emits a clicking sound to indicate to the user that the secondary equipment is being adjusted. After adjustment, the end of the reset pressure plate 204a causes the first flexible plate 205c to deform due to the arc shape of the second flexible plate 205d. This causes the pressure plate 204a to engage inside the first flexible plate 205c, forming a limit. Simultaneously, the pressure plate 204a causes the second inclined surface 203b of the limiting plate 203a to engage inside the first inclined surface 202b, placing the transmission rod 202a in a limited position. This causes the protruding rod 202c and teeth at the end of the transmission rod 202a to engage. End 202d is also in a fixed state, so the tooth end 202d and tooth groove 102c form a limit, and the open ring 102a is also limited, so that the secondary pressure plate body 101c connected to the open ring 102a cannot be adjusted. Then, by closing the protective cover 101d and squeezing the contact surface 204i, the rotating block 204h and the movable plate 204g squeeze the rubber block 204f. After the protective cover 101d is closed and locked by the electric lock 101b, the protective cover 101d can completely limit the pressure plate 204a.

[0046] In summary, the secondary device has relatively complete prompts and limit functions, which reduces the risk of accidental touches or incorrect usage by users and improves safety during use.
