Description

Technical Field

[0001] The invention relates to the technical field of installation of lightning drive devices, in particular to a passive corona field lightning drive device. Background Art

[0002] Passive corona field lightning arresters utilize the "tip-like effect" created by multiple short metal needles. This creates a significantly higher electric field around the device than the protected object, but lower than that of a traditional lightning rod, thus keeping the protected object relatively safe. Existing passive corona field lightning arresters are installed by bolting the main body to the mounting base. However, this makes it difficult to align the screw holes during installation, reducing installation efficiency. Furthermore, existing discharge needles are not convenient or quick to secure to the main body, making operation more cumbersome.

[0003] To solve the above problems, a Chinese patent with publication number CN215267073U discloses a passive corona field passive lightning arrester, comprising a lightning arrester body, a plurality of discharge needles evenly arranged on the top of the lightning arrester body, a mounting base provided at the bottom of the lightning arrester body, fastening bolts symmetrically provided on the bottom side of the lightning arrester body, symmetrically provided with screw holes A for the fastening bolts to pass through at the edge of the bottom side surface of the lightning arrester body, symmetrically provided with screw holes B at the edge of the top surface of the mounting base, the fastening bolts pass through the screw holes A to the inside of the screw holes B, and a limiting component is provided on the bottom end face of the lightning arrester body; the patent facilitates the alignment of the screw holes A and the screw holes B through the designed limiting component, so that workers can quickly fix and install the fastening bolts, making the operation easier.

[0004] The following problems exist during the actual use of the above patent: 1. The limiting component can facilitate the alignment of screw hole A and screw hole B, so that the staff can quickly fix the fastening bolts and install them, but the staff still needs to use tools to assist in rotating the fastening bolts for installation, and needs to repeat the same operation twice, which is cumbersome; 2. The fastening bolts and tools need to be carried separately. If the staff accidentally lose them when going to the construction site, it will directly affect the fixed installation of the lightning arrester body. Summary of the Invention

[0005] The present invention aims to provide a passive corona field lightning arrester to solve the problem of complicated operation of the fixed installation method of the existing lightning arrester body.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical scheme: a passive corona field lightning driver, comprising a lightning driver body and a base, characterized in that: bottom blocks are symmetrically provided on both sides of the bottom of the lightning driver body, a side block is provided on the bottom block, a bottom groove is provided at the bottom of one end of the side block away from the bottom block, a limiting block is slidably connected in the bottom groove, a first spring is provided between the limiting block and the bottom groove, and an end of the limiting block away from the first spring is provided with an arc surface; a circular groove is vertically provided on the base, and the lightning driver body can move vertically and rotate in the circular groove; guide grooves are vertically provided on both sides of the circular groove near the top of the base, and the circular groove has a first arc groove on both sides near the bottom of the base, and the first arc groove is connected to the guide groove; an end of the first arc groove near the guide groove is provided with an inclined surface for resisting the arc surface, and an end of the first arc groove away from the guide groove is provided with a limiting groove, and the limiting block slides with the limiting groove; the side block and the limiting block can both move vertically in the guide groove, and the side block and the limiting block can both move circumferentially in the first arc groove.

[0007] The principles and advantages of this solution are:

[0008] 1. In this scheme, the lightning driver body is placed downwardly into the circular groove, and the lightning driver body drives the bottom block and the side block to move synchronously, so that the side block and the limit block all move downward in the guide groove; then the lightning driver body is rotated to make the side block and the limit block move synchronously; during the movement of the side block and the limit block, the side block moves along the path of the first arc groove, and at the same time the arc surface contacts the inclined surface, so that the inclined surface squeezes the limit block through the arc surface to move upward along the bottom groove, and the first spring is compressed, allowing the limit block and the side block to move together in the first arc groove; when the limit block is vertically opposite to the limit groove, the limit block slides into the limit groove under the action of the first spring, thereby realizing the positioning of the side block, and then realizing the positioning of the lightning driver body; therefore, compared with the existing technology, this scheme only needs to be rotated to complete the fixed installation of the lightning driver body, and the rotation number of this scheme is only required once, and it does not need to be rotated one circle, that is, the fixed installation method of the lightning driver body of this scheme is simpler to operate.

[0009] 2. This solution can prevent the lightning arrester body from moving in the vertical direction by allowing the side blocks and the limit blocks to move in the first arc-shaped groove, that is, prevent the lightning arrester body from being taken out of the circular groove or falling, thereby improving the stability of the fixed installation of the lightning arrester body.

[0010] 3. The side blocks and limit blocks of this solution are integrated with the main body of the lightning arrester, so there will be no problem of loss, thereby ensuring the fixed installation of the main body of the lightning arrester.

[0011] Furthermore, side blocks are provided on both sides of the mine-dispelling device body, and the side blocks are located between the two bottom blocks along the circumferential direction of the circular groove, and a first arc block is provided on the side blocks; second arc grooves are provided on both sides of the top of the base, and the first arc block can move vertically and circumferentially in the second arc groove; chambers are provided on both sides of the circular groove in the base, and the chambers are communicated with the second arc groove; a fixed block is provided in the chamber, and a transverse groove is provided at the bottom of the fixed block, and a tightening block for abutting against the first arc block is slidably connected in the transverse groove, and a second spring is provided between the tightening block and the transverse groove; and it also includes a linkage mechanism that drives the tightening block to abut against the first arc block as the first arc block moves circumferentially in the second arc groove.

[0012] With the above arrangement, when the lightning arrester body moves downward, the lightning arrester body will also drive the first arc-shaped block to move downward, and the first arc-shaped block will extend into the second arc-shaped groove.

[0013] During the rotation of the lightning driver body, the lightning driver body drives the first arc block to rotate synchronously, and drives the clamping block to abut against the first arc block through the linkage mechanism, thereby realizing the limitation of the first arc block, that is, the first arc blocks on both sides of the lightning driver body can be clamped by the clamping blocks on both sides, thereby strengthening the positioning effect of the lightning driver body and improving the stability of the positioning of the lightning driver body.

[0014] Furthermore, the linkage mechanism includes an arc-shaped rack fixed to the bottom of the first arc-shaped block and a rotating shaft rotatably connected to the chamber, and the arc-shaped rack can move vertically and circumferentially in the second arc-shaped groove; a first gear and a disc are coaxially connected to the rotating shaft, and the first gear in a chamber can directly engage with an arc-shaped rack; a reversing shaft is rotatably connected in the other chamber, and a reversing gear is coaxially connected to the reversing shaft, and the reversing gear can engage with another arc-shaped rack, and the reversing gear engages with the first gear in the same chamber; the thickness of the disc gradually increases from top to bottom, and the disc abuts against the tightening block.

[0015] Through the above arrangement, during the downward movement of the lightning arrester body, the lightning arrester body will also drive the first arc block to move downward, the first arc block extends into the second arc groove, and the first arc block drives the arc rack to synchronously extend into the second arc groove; during the rotation of the lightning arrester body, the lightning arrester body drives the first arc block to rotate synchronously; in the left chamber: the arc rack on the left is engaged with the reversing gear to drive the reversing gear to rotate, the reversing gear is engaged with the first gear on the left to drive the first gear on the left to rotate, the first gear on the left drives the left rotating shaft to rotate, and the left rotating shaft drives the left disc to rotate movement; in the right chamber: the arc-shaped rack on the right is engaged with the first gear on the right to drive the first gear on the right to rotate, the first gear on the right drives the right shaft to rotate, and the right shaft drives the right disc to rotate; in this way, the rotation directions of the shaft and the disc in the two chambers are the same. Since the thickness of the disc gradually decreases from top to bottom, and the end face of the disc is against the tightening block, the position where the thickness of the disc is larger squeezes the tightening block to move in the direction of the first arc-shaped block, the second spring is compressed, and the shaft continues to rotate. When the mine-dispelling device body is positioned, the tightening block is against the first arc-shaped block.

[0016] Furthermore, the disc is cam-shaped, and the position of the raised portion of the disc is the maximum thickness of the disc; a second arc block is provided on the side wall of the first arc block, and the cross-section of the second arc block is L-shaped; a wedge surface is provided at the end of the second arc block away from the first arc block, and the second arc block can move vertically and circumferentially in the second arc groove; a vertical groove is provided on the fixed block, and a lifting block is slidably connected in the vertical groove, and a third spring is provided between the lifting block and the fixed block, and the lifting block is against the disc; a side groove is provided on the side wall of the lifting block, and a wedge block for being squeezed by the wedge surface is slidably connected in the side groove, and a fourth spring is provided between the wedge block and the side groove, and the wedge block is located on the movement trajectory of the wedge surface, and the wedge block can be against the top of the second arc block.

[0017] Through the above-mentioned arrangement, during the downward movement of the first arc block, the first arc block will also drive the second arc block to move downward, that is, the second arc block moves downward in the second arc groove, so that the wedge surface squeezes the wedge block to move into the side groove, and the fourth spring is compressed; during the rotation of the disc, the raised part of the disc squeezes the lifting block to move upward, and the third spring is stretched; during the upward movement of the lifting block, the lifting block drives the wedge block to move upward. When the mine driver body is positioned, the wedge block passes over the wedge surface and abuts against the top of the second arc block, that is, the wedge block is pressed on the second arc block, thereby avoiding vertical movement of the mine driver body and thereby improving the stability of the positioning of the mine driver body.

[0018] Furthermore, a supporting mechanism is provided in the chamber, and the supporting mechanism and the disc are located on both sides of the second arc-shaped groove; the supporting mechanism includes inclined grooves opened on both sides of the chamber, and the spacing between the two inclined grooves gradually decreases from top to bottom, and a moving block is slidably connected in the inclined groove; the chamber is communicated with the circular groove, and one moving block can be offset against the mine-displacing device body, and the other moving block can be offset against the first arc-shaped block; it also includes a supporting part that drives the two moving blocks to move at the same time as the rotating shaft rotates.

[0019] Through the above-mentioned arrangement, during the rotation of the rotating shaft, the two moving blocks are driven to move at the same time through the support part. Since the moving blocks move in the inclined groove, the two moving blocks can also move laterally, and the two moving blocks are away from each other; that is, one moving block moves in the direction of the lightning driver body, and the other moving block moves in the direction of the first arc block; the rotating shaft continues to rotate, and when the lightning driver body is positioned, one moving block is against the lightning driver body, and the other moving block is against the first arc block; therefore, the lightning driver body can be clamped by the moving blocks on both sides of the lightning driver body, thereby improving the stability of the positioning of the lightning driver body; and, by clamping the first arc block by the moving block and the clamping block, the positioning of the first arc block can be achieved, and then the positioning of the lightning driver body can be achieved, that is, the stability of the positioning of the lightning driver body is improved.

[0020] Furthermore, the support part includes a wall groove opened on the chamber, a second gear coaxially connected to the rotating shaft, a bar rack is slidably connected in the wall groove, and the bar rack is engaged with the second gear; movable grooves are provided on both sides of the bar rack, the moving block is slidably connected to the movable groove, and a fifth spring is provided between the moving block and the movable groove.

[0021] Through the above-mentioned arrangement, during the rotation of the rotating shaft, the rotating shaft will also drive the second gear to rotate, the second gear will engage with the bar rack to drive the bar rack to move upward, and the bar rack will drive the two moving blocks to move upward; since the moving block is slidingly connected to the movable groove and the inclined groove, the moving block will also move laterally during the upward movement, and the fifth spring will be stretched, causing the two moving blocks to move away, that is, one moving block moves toward the direction of the mine driver body, and the other moving block moves toward the direction of the first arc block.

[0022] Furthermore, auxiliary blocks are provided on both sides of the base, and a positioning block is vertically slidably connected to the auxiliary block, and a sixth spring is provided between the positioning block and the auxiliary block; the rotating shaft is rotatably connected to the base, and the positioning block is against the rotating shaft; a positioning hole is provided on the rotating shaft, and the positioning block is located on the motion trajectory of the positioning hole, the positioning block and the positioning hole are staggered, and the positioning block and the positioning hole are slidably matched.

[0023] Through the above-mentioned arrangement, during the rotation of the rotating shaft, the rotating shaft will also drive the positioning hole to rotate synchronously. When the lightning arrester body is positioned, the positioning block is vertically opposite to the positioning hole, so that the positioning block slides into the positioning hole under the action of the sixth spring, thereby realizing the positioning of the rotating shaft and preventing the rotating shaft from rotating. The rotation of the lightning arrester body is then prevented by the first gear, the arc-shaped rack, and the first arc-shaped block, thereby improving the stability of the positioning of the lightning arrester body.

The positioning block 81 and the positioning hole 83 are staggered, and the positioning block 81 and the positioning hole 83 are slidably matched.

[0041] The specific implementation process is as follows:

[0042] When in use, the lightning arrester body 10 is placed downwardly into the circular groove 30, and the lightning arrester body 10 drives the bottom block 20 and the side block 21 to move synchronously, so that the side block 21 and the limit block 23 all move downward in the guide groove 31; then the lightning arrester body 10 is rotated to make the side block 21 and the limit block 23 move synchronously; during the movement of the side block 21 and the limit block 23, the side block 21 moves along the path of the first arc groove 32, and at the same time the arc surface 25 contacts the inclined surface 33, so that the inclined surface 33 squeezes the limit block 23 through the arc surface 25 to move upward along the bottom groove 22, and the first spring 24 is compressed, so that the limit block 23 and the side block 21 move together in the first arc groove 32; when When the limit block 23 is vertically opposite to the limit groove 34, the limit block 23 slides into the limit groove 34 under the action of the first spring 24, thereby realizing the positioning of the side block 21, and then realizing the positioning of the lightning arrester body 10; therefore, compared with the existing technology, this scheme only needs to complete the positioning of the lightning arrester body 10 by rotation, and the rotation of this scheme only needs one time, and does not need to be rotated one circle, that is, the fixed installation method of the lightning arrester body 10 of this scheme is simpler to operate; in addition, the side block 21 and the limit block 23 are integrated with the lightning arrester body 10, and there will be no problem of loss, thereby ensuring the fixed installation of the lightning arrester body.

[0043] During the downward movement of the mine arrester body 10, the mine arrester body 10 will also drive the first arc block 41 to move downward, the first arc block 41 extends into the second arc groove 42, and the first arc block 41 drives the arc rack 50 to synchronously extend into the second arc groove 42; during the rotation of the mine arrester body 10, the mine arrester body 10 drives the first arc block 41 to rotate synchronously; in the left chamber 43: the arc rack 50 on the left is engaged with the reversing gear 54 to drive the reversing gear 54 to rotate, the reversing gear 54 is engaged with the first gear 52 on the left to drive the first gear 52 on the left to rotate, the first gear 52 on the left drives the left rotating shaft 51 to rotate, and the left rotating shaft 51 drives the left disc 53 to rotate; in the right chamber 43: the arc rack 50 on the right is engaged with the first gear 52 on the right to drive the first As the gear 52 rotates, the first gear 52 on the right drives the rotating shaft 51 on the right to rotate, and the rotating shaft 51 on the right drives the disc 53 on the right to rotate; this ensures that the rotating shaft 51 and the disc 53 in the two chambers 43 have the same rotation direction. Since the thickness of the disc 53 gradually decreases from top to bottom, and the end face of the disc 53 abuts against the tightening block 46, the thicker position of the disc 53 squeezes the tightening block 46 toward the direction of the first arc block 41. The second spring 47 is compressed, and the rotating shaft 51 continues to rotate. When the mine arrester body 10 is positioned, the tightening block 46 abuts against the first arc block 41, that is, the first arc blocks 41 on both sides of the mine arrester body 10 can be clamped by the tightening blocks 46 on both sides, thereby strengthening the positioning effect of the mine arrester body 10 and improving the stability of the positioning of the mine arrester body 10.

[0044] During the rotation of the rotating shaft 51, the rotating shaft 51 will also drive the second gear 73 to rotate, and the second gear 73 engages with the bar rack 74 to drive the bar rack 74 to move upward, and the bar rack 74 drives the two moving blocks 71 to move upward; because the moving block 71 is slidably connected with the movable groove 75 and the inclined groove 70, the moving block 71 will also move laterally during the upward movement of the moving block 71, and the fifth spring 76 is stretched, so that the two moving blocks 71 move away from each other, that is, one moving block 71 moves toward the direction of the mine expeller body 10, and the other moving block 71 moves toward the direction of the first arc block 41 ; The rotating shaft 51 continues to rotate, and when the mine arrester body 10 is positioned, one moving block 71 abuts against the mine arrester body 10, and the other moving block 71 abuts against the first arc-shaped block 41; therefore, the moving blocks 71 on both sides of the mine arrester body 10 can clamp the mine arrester body 10, thereby improving the stability of the positioning of the mine arrester body 10; and, by clamping the first arc-shaped block 41 through the moving block 71 and the abutting block 46, the positioning of the first arc-shaped block 41 can be achieved, thereby achieving the positioning of the mine arrester body 10, that is, improving the stability of the positioning of the mine arrester body 10.

[0045] During the downward movement of the first arc block 41, the first arc block 41 will also drive the second arc block 60 to move downward, that is, the second arc block 60 moves downward in the second arc groove 42, so that the wedge surface 61 squeezes the wedge block 65 to move into the side groove 64, and the fourth spring 66 is compressed; during the rotation of the disc 53, the raised portion of the disc 53 squeezes the lifting block 62 to move upward, and the third spring 63 is stretched; during the upward movement of the lifting block 62, the lifting block 62 drives the wedge block 65 to move upward. When the mine arrester body 10 is positioned, the wedge block 65 passes over the wedge surface 61 and abuts against the top of the second arc block 60, that is, the wedge block 65 is pressed on the second arc block 60 to avoid vertical movement of the mine arrester body 10, thereby improving the stability of the positioning of the mine arrester body 10.

[0046] During the rotation of the rotating shaft 51, the rotating shaft 51 will also drive the positioning hole 83 to rotate synchronously. When the lightning arrester body 10 is positioned, the positioning block 81 is vertically opposite to the positioning hole 83, so that the positioning block 81 slides into the positioning hole 83 under the action of the sixth spring 82, thereby realizing the positioning of the rotating shaft 51 and preventing the rotating shaft 51 from rotating. Then, the rotation of the lightning arrester body 10 is prevented by the first gear 52, the arc-shaped rack 50, and the first arc-shaped block 41, thereby improving the stability of the positioning of the lightning arrester body 10.
