Description

Technical Field

[0001] The utility model relates to the technical field of DC high-voltage generators, in particular to a protective structure of a DC high-voltage generator. Background Art

[0002] The DC high-voltage generator is an important instrument used to test high-voltage electrical equipment and other devices. It is generally suitable for power maintenance departments, industrial and mining, metallurgical, steel and other enterprise power departments to perform DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, generators, and high-voltage switches.

[0003] In the Chinese utility model patent with publication number CN218042067U, a protective structure for a DC high-voltage generator is disclosed. The top cover is rotated to a horizontal position and supported, the hook is removed from the outside of the hook ring, the DC high-voltage generator body is taken out of the placement slot, and the limit head at the bottom of the DC high-voltage generator body is aligned with the group opening hole and placed into the embedded slot. The body is then rotated to dislocate it so that the limit head and the buckle hole are dislocated, and then the DC high-voltage generator is taken out of the box body and installed and positioned. However, after the experiment is completed, the body still needs to be rotated in the opposite direction to align the body with the limit and the buckle hole, and then the body is completely removed and placed horizontally in the placement slot. Therefore, in use, the body needs to be taken out of the placement slot first and then put back into the placement slot after the experiment is taken out. However, the placement slot space is usually adapted to the size of the body slot, so that the distance between the body and the inner wall of the placement slot is small, and the space is relatively narrow, which is not conducive to taking and placing, thereby affecting the work efficiency of the experiment.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-7 As shown, the utility model provides a technical solution, a protective structure for a DC high-voltage generator, comprising a box body 1, a box cover 2 is provided on the top of the box body 1, and the interior of the box body 1 is used to place a DC high-voltage generator body 3; a bracket 4 is provided at the bottom of the box body 1, and the bracket 4 is used to place the DC high-voltage generator body 3; the bottom of the mounting plate 5 is fixedly connected to a rotating shaft 6, and both ends of the rotating shaft 6 are provided with a gear lever 20, the gear lever 20 is located near the edge of the end face of the rotating shaft 6, and the outer side of the gear lever 20 is slidably connected to a control frame 7, and one end of the control frame 7 is provided with a first drive component 12, and the first drive component 12 is installed inside the box body 1, and is used for the first drive component 12 to push the gear lever 20 to move, so that the gear lever 20 drives the rotating shaft 6 and the mounting plate 5 to rotate.

[0032] The detachable connection between the mounting plate 5 and the DC high-voltage generator body 3 can be connected by a snap-on connection. During assembly, the bottom of the DC high-voltage generator body 3 is inserted into the interior of the mounting plate 5, and a snap-on slot is provided at the corresponding mounting plate 5, so that the snap-on slot and the DC high-voltage generator body 3 are snap-connected for easy assembly and disassembly; a connecting rod 16 is fixedly connected to the outside of the bracket 4, and one end of the connecting rod 16 is fixedly connected to the rotating shaft 6, so that during rotation, the bracket 4 is driven to rotate at the same time, playing a supporting role, reducing the load at the connection between the DC high-voltage generator body 3 and the mounting plate 5, and at the same time, the bracket 4 is provided with several holes and grooves to form a hollow shape, forming a larger operating space, which is convenient for taking and placing the DC high-voltage generator body 3, and the length of the bracket 4 is less than the length of the DC high-voltage generator body 3; anti-collision pads are provided on the bracket 4 and the box cover 2 to play a protective effect; when in use, the shape of the control frame 7 is T-shaped, and a rectangular groove is provided inside one end of the T-shaped frame, and the gear rod 20 passes through the rectangular groove, and the width of the rectangular groove is adapted to the diameter of the gear rod 20, and a protrusion is provided inside the rectangular groove for limiting the gear rod 2 0 relative sliding space up and down; in the initial state, the mounting plate 5 is vertically distributed. At this time, the horizontal angle between the center of the gear lever 20 and the center of the rotating shaft 6 is 45 degrees. Then, when the control frame 7 pushes the gear lever 20 to move, the gear lever 20 is subjected to a horizontal thrust. Under the restriction of the circular end face of the rotating shaft 6, the rotating shaft 6 is driven to rotate. At the same time, the gear lever 20 moves upward relatively inside the control frame 7, and when it moves to the top inside the control frame 7, the gear lever 20 just moves to the highest point of the rotating shaft 6. At this time, the gear lever 20 drives the rotating shaft 6. The shaft 6 rotates a full 45°, and then continues to push, causing the lever 20 to start moving downward. When the lever 20 moves to the lowest point inside the control frame 7, it just contacts the top of the protrusion. At this time, the position of the lever 20 is just symmetrical with the initial position of the lever 20 about the middle of the rotating shaft 6, and the rotating shaft 6 rotates a total of 90°, thereby driving the mounting plate 5 to rotate 90°, so that the horizontally placed DC high-voltage generator body 3 is rotated from a horizontal state to a vertical state, and then only the wiring needs to be completed to carry out the experiment, thereby improving the efficiency of picking and placing.

[0033] The top of the box body 1 and the side close to the mounting plate 5 are both provided with openings, and the box cover 2 is used to cover the top opening, and the side wall of the box cover 2 is provided with a sealing plate 18, so that after the box cover 2 is closed on the box body 1, the sealing plate 18 closes the opening on the side wall of the box body 1; when in use, the box cover 2 and the box body 1 are hinged, and the contact positions between the box body 1 and the box cover 2 are all provided with sealing gaskets for sealing, and a support plate is provided on one side of the box cover 2 for supporting the box cover 2 after the box cover 2 is opened, so as to keep the box body 1 and the box cover 2 stable after opening; a pad is detachably provided on one side of the box body 1, and the thickness of the pad is the same as the thickness of the bottom of the box body 1, so that after the mounting plate 5 is flipped 90°, the pad is set below the mounting plate 5 to keep the mounting plate 5 stable.

[0034] The rotating shaft 6 includes a rotating rod 601, the outer surface of which is connected to the mounting plate 5 and the bracket 4 respectively. A control block 602 is provided at each end of the rotating rod 601. The side of the control block 602 away from the rotating rod 601 is connected to one end of the shift lever 20. A limit post 8 is inserted into the side of the control block 602 to limit the rotation of the control block 602. The end of the limit post 8 away from the control block 602 is provided with a buffer assembly, one end of which passes through the control frame 7; so that the control frame 7 can push the limit post 8 to slide an appropriate distance via the buffer assembly.

[0035] The bottom of the limiting column 8 is slidably sleeved on the outside of the limiting mechanism 9. The limiting mechanism 9 is arranged inside the box body 1 to limit the movement distance of the limiting column 8.

[0036] When in use, a socket 603 is provided on the outer surface of the control block 602, and the limiting column 8 passes through the socket 603, and the control frame 7 is pushed to move through the first drive component 12. At this time, the control block 602 is difficult to rotate under the restriction of the limiting column 8, and then the first drive component 12 first pushes the rotating shaft 6 to move horizontally through the control frame 7, and further drives the DC high-voltage generator body 3 and the bracket 4 to move horizontally, so that the DC high-voltage generator body 3 is away from one end of the mounting plate 5 away from the corresponding inner wall of the box body 1, and then the limiting column 8 and the socket 603 are disengaged. After that, the control frame 7 pushes the mounting plate 5 to rotate. When retracting, since the limit column 8 and the socket 603 are still in contact at this time, the mounting plate 5 rotates first. After rotating to an appropriate angle, it cannot continue to rotate because it is supported by the inside of the control frame 7 and the gear lever 20, and then the mounting plate 5 is pulled to move horizontally, and the limit column 8 passes through the socket 603 again, so that one end of the DC high-voltage generator body 3 contacts the inner wall of the box body 1, and there is no need to reserve rotation space at the top position of the DC high-voltage generator body 3, thereby improving the utilization rate of the internal space of the box body 1.

[0037] The buffer assembly includes a guide rod 10, one end of which passes through the control frame 7, and the other end of the guide rod 10 is connected to one end of the limit column 8. The guide rod 10 is located between the control frame 7 and the limit column 8 and is sleeved with a second elastic member 11 on the outside; the top of the limit column 8 is provided with an arc-shaped protrusion; when in use, the second elastic member 11 is a spring, a U-shaped groove is provided at the bottom of the control frame 7, and the guide rod 10 passes through the U-shaped groove, the width of the U-shaped groove is greater than the diameter of the guide rod 10, which facilitates the guide rod 10 to move upward from the bottom to the U-shaped groove, the axis of the guide rod 10 corresponds to the edge of the socket 603, and the top height of the guide rod 10 is lower than the top surface height of the limit column 8, preventing the guide rod 10 from being inserted into the socket 603, and at the same time facilitating the extrusion of the guide rod 10, and a slope can also be provided at one end of the guide rod 10.

[0038] In the initial state, the total length of the initial length of the second elastic member 11 and the limiting column 8 is smaller than the distance between the connection between the control frame 7 and the first drive component 12 and the control block 602, so that when the control block 602 is on the left side of the limiting column 8, the connection between the first drive component 12 and the control frame 7 can be located on the right side of the second elastic member 11 without compressing the second elastic member 11.

[0039] The first driving assembly 12 adopts an electric push rod, which pushes the control frame 7 to move. At the same time, the control frame 7 pushes the limiting column 8 to move through the second elastic member 11, so that the limiting column 8 and the control frame 7 move at the same time to ensure that the control block 602 and the limiting column 8 will not separate. As the limiting column 8 moves from one side of the limiting mechanism 9 to the other side, that is, after moving to the limit, the limiting column 8 is blocked and no longer moves, thereby causing the control frame 7 to start the second elastic member 11 to compress, and the control frame 7 continues to move, so that the limiting column 8 and the control block 602 are in a state of being locked. 2 disengages, and then drives the control block 602 to rotate 90°; at the same time, the second elastic member 11 is fixedly connected to the limiting post 8 and contacts the control frame 7. When resetting, since the control block 602 rotates 90° again, the socket 603 and the limiting post 8 are aligned, so that the limiting post 8 is inserted into the control block 602 again. As it moves on the limiting post 8, the socket 603 moves to the arc-shaped protrusion, and the protrusion further drives the limiting post 8 to start the reset movement, reset on the limiting mechanism 9 and move back to the inside of the box body 1.

[0040] The limiting mechanism 9 includes a U-shaped limiting frame 901, and the two sides of the U-shaped limiting frame 901 are arranged along the movement direction of the limiting column 8. The bottom of the limiting frame 901 is arranged inside the box body 1. The inner side of the limiting frame 901 is connected with a positioning rod, and the outer side of the positioning rod is slidably connected to the limiting column 8; when in use, the positioning rod is elliptical and passes through the limiting column 8, so that the limiting column 8 can slide inside the U-shaped limiting frame 901 and block the movement of the limiting column 8 through the side wall of the limiting frame 901.

[0041] A horizontal motion control component is provided between the first drive component 12 and the box body 1, for adjusting the position of the first drive component 12 to control the horizontal movement of the mounting plate 5; the control component includes a second drive component 19, one end of the second drive component 19 is connected to the inner wall of the box body 1, the output end of the second drive component 19 is connected to the push frame 15, and one side of the push frame 15 is connected to the first drive component 12; a first slide groove 14 is provided on the inner bottom wall of the box body 1, the first slide groove 14 is located below the limit column 8, and the width of the first slide groove 14 is greater than the width of the limit column 8; a second slide groove 1 is provided at the bottom of the first slide groove 14 7. The inner bottom wall of the second slide groove 17 is connected to the first elastic member 902, and the top of the first elastic member 902 is connected to the bottom of the limit frame 901; a self-locking mechanism is provided on one side of the control frame 7, and the self-locking mechanism is used to lock the gear lever 20; the self-locking mechanism includes an electromagnet on one side of the control frame 7, and a magnetic pin is provided on one side of the electromagnet, and one end of the pin is plugged into the gear lever 20; when in use, the magnetic pin is pushed to move by turning on the electromagnet, and the pin is inserted into the inside of the gear lever 20, thereby locking the gear lever 20, so that when the first drive component 12 pulls the rotating shaft 6 through the gear lever 20, the rotating shaft 6 will not rotate.

[0042] When in use, the two opposite sides of the pushing frame 15 are fixedly connected to the limiting cylinder 13, the inner wall of the limiting cylinder 13 is slidably connected to the corresponding control frame 7, the second driving component 19 adopts an electric push rod, the first elastic member 902 adopts a spring, and one end of the limiting column 8 is provided with a slope; after the DC high-voltage generator body 3 is rotated to a vertical state, the pushing frame 15 is driven to move by the second driving component 19, and the pushing frame 15 further pulls the rotating shaft 6 to move through the first driving component 12, and the rotating shaft 6 further drives the DC high-voltage generator body 3 to move through the mounting plate 5, and then moves the DC high-voltage generator body 3 to the middle of the box body 1, and uses the box body 1 as a whole as a supporting component of the DC high-voltage generator body 3 to improve the support surface of the bottom and improve the stability of the device.

[0043] Among them, when moving to the middle, the control block 602 is locked, and since the position of the socket 603 after rotation does not correspond to the limit column 8, the circular surface of the control block 602 and the slope of the limit column 8 push the limit column 8 downward, thereby causing the control block 602 and the mounting plate 5 to move to the other side of the limit column 8.

[0044] Then, when returning, since the limit column 8 has been reset, that is, the height is adapted to the height of the socket 603, and the guide rod 10 is located at the edge of the limit column 8, and the axis of the guide rod 10 is corresponding to the edge of the socket 603, then when the control block 602 moves in the reverse direction, the edge of the socket 603 is always misaligned with the guide rod 10, making it impossible to insert into the socket 603, and then under the arc surface of the control block 602, the guide rod 10 is pushed downward again, that is, the limit column 8 is driven to compress the first elastic member 902. When the control frame 7 moves to above the guide rod 10, due to continued movement, the control block 602 gradually moves along the slope to the other side of the limit column 8, and then the guide rod 10 moves from bottom to top into the U-shaped groove of the control frame 7, and then continues to move. At this time, the limit column 8 is still located at the leftmost side of the limit frame 901, and then begins to compress the second elastic member 11, and after being compressed to an appropriate distance, the self-locking mechanism is unlocked, so that the control block 602 can be rotated to facilitate rotating the jack 603 to the appropriate position, and then pulling the DC high-voltage generator body 3 back.
