[0044] Embodiment 1

[0045] like Figure 1-7 As shown, the high-voltage discharge needle mounting structure proposed in the present application includes a mounting plate body 1 and a positive high-voltage connecting ejector pin 4 and a negative high-voltage connecting ejector pin 5 arranged at its ends. The positive high-voltage connecting ejector pin 4 and the negative high-voltage connecting ejector pin 5 are fixedly connected to the right end of the mounting plate body 1. Figure 1 . It also includes: a plurality of fixed shells 2 arranged on the inner wall of the mounting plate 1 and distributed in a ring shape, there are eight fixed shells 2, and the surfaces of the eight fixed shells 2 away from the mounting plate 1 are provided with through holes 11, the inner diameter of the through hole 11 is slightly larger than the outer diameter of the high-voltage discharge needle 3, so that the high-voltage discharge needle 3 can be smoothly inserted into the through hole 11; a needle guide plate 7 for guiding and positioning the high-voltage discharge needle 3 and arranged in the fixed shell 2, a U-shaped cavity is opened in the mounting plate 1, a pair of arc-shaped wire tubes 6 are fixedly arranged in the U-shaped cavity, and a needle traction member 8 for pulling the eight needle guide plates 7 is commonly arranged in the two arc-shaped wire tubes 6, and the needle traction member 8 is arranged in the U-shaped cavity. The interior of the mounting plate 1 is provided with a first connecting line 161 and a second connecting line 162, the first connecting line 161 and the second connecting line 162 are electrically connected to the negative high-voltage connecting pin 5 and the positive high-voltage connecting pin 4 respectively, and the specific layout of the first connecting line 161 and the second connecting line 162 is referred to. Figure 7 .

[0046] Furthermore, the eight fixed housings 2 are each provided with a conductive sheet 13 connected to the eight high-voltage discharge needles 3, and each two adjacent conductive sheets 13 are electrically connected to the first connection line 161 and the second connection line 162, respectively. Figure 7 , a certain distance is maintained between discharge needles of different polarities. The discharge needle connected to the positive high voltage generates positive ions, and the discharge needle connected to the negative high voltage generates negative ions, so that the positive and negative ions neutralize the static electricity in the working environment.

[0047] Specifically, the needle traction member 8 includes a traction main rope 802 respectively arranged in two arc-shaped wire tubes 6, and the traction main rope 802 is movably connected in the arc-shaped wire tube 6. One end of the mounting plate body 1 is rotatably connected to a winding drum 801, and the ends of the two traction main ropes 802 are respectively reversely wound around the outer ring of the winding drum 801, and the ends of the traction main rope 802 are fixedly connected to the winding drum 801 to prevent the traction main rope 802 from being separated when the winding drum 801 rotates reversely, and the traction main rope 802 can be smoothly wound when the winding drum 801 rotates forward. Four traction branch ropes 803 are fixedly connected to the two traction main ropes 802, and the traction branch ropes 803 pass through the inner wall of the mounting plate body 1 and the outer wall of the fixed shell 2 and are fixedly connected to the corresponding needle body guide plate 7; the number of the fixed shell 2, the needle body guide plate 7, the traction branch ropes 803, and the high-voltage discharge needle 3 can also be six or ten, which is not limited here.

[0048] Both ends of the arc-shaped wire tube 6 are fixedly embedded with guide rings 9, and the inner ring of the guide ring 9 is fixedly connected with a loss reduction ring 10. The traction main rope 802 slides through the loss reduction ring 10, guiding the traction main rope 802 and reducing the wear of the traction main rope 802; the needle body guide plate 7 is provided with a guide groove 71 on the side close to the through hole 11, and an annular electromagnet 72 located on one side of the conductive sheet 13 is fixedly embedded in the guide groove 71. The outer diameter of the conductive sheet 13 is smaller than the inner diameter of the annular electromagnet 72, so that the high-voltage discharge needle 3 can contact the conductive sheet 13 smoothly. When the high-voltage discharge needle 3 and the conductive sheet 13 are in conflict with each other, the first connecting line 161 and the second connecting line 162 are energized to keep the high-voltage discharge needle 3 energized.

[0049] The working principle of this embodiment is as follows: when installing the discharge needle, firstly, a plurality of annular electromagnets 72 are energized, and the plurality of annular electromagnets 72 are connected in series, and then a plurality of high-voltage discharge needles 3 are sequentially inserted into the guide groove 71 through the through hole 11. It is worth noting that the tip of the high-voltage discharge needle 3 is away from the fixed housing 2. Since the annular electromagnet 72 has magnetic attraction after being energized, the high-voltage discharge needle 3 can be more smoothly inserted into the guide groove 71 through the through hole 11, and can play a role in preliminary positioning of the high-voltage discharge needle 3. Subsequently, the winding drum 801 is rotated clockwise with the help of the external rectangular rod. A rectangular groove is provided at the outer end of the winding drum 801. The rectangular rod is inserted into the rectangular groove. The winding drum 801 is rotated so that one end of the two groups of traction ropes 802 are both wound around the outside of the winding drum 801. When the two groups of traction ropes 802 are rolled up, the eight traction branch ropes 803 will be driven to move toward the inside of the mounting plate 1, thereby pulling the eight fixed shells 2 away from the corresponding perforations 11, so that the eight high-voltage discharge needles 3 move toward the direction of the corresponding conductive sheets 13, and contact the corresponding conductive sheets 13 respectively. When the high-voltage discharge needles 3 contact the conductive sheets 13, the annular electromagnet 72 is powered off and loses its magnetism. It is worth noting that the side wall of the needle guide plate 7 is fixedly connected with a guide rod, which is slidably connected to the inner wall of the fixed shell 2. By setting the guide rod, the needle guide plate 7 can move smoothly.

[0050] Embodiment 2

[0051] The present invention and the first embodiment adopt the same inventive concept. Compared with the first embodiment, Figure 3-6 As shown, this embodiment also includes: a locking needle assembly 15 for locking the high-voltage discharge needle 3, a pneumatic part 12 for driving the locking needle assembly 15 is arranged in the fixed housing 2, the needle guide plate 7 moves and squeezes the pneumatic part 12 to provide power for the locking needle assembly 15, and when the traction rope 803 pulls the needle guide plate 7 to move, the needle guide plate 7 will trigger the pneumatic part 12, and the locking needle assembly 15 is driven by the pneumatic part 12. Specifically, the locking needle assembly 15 includes an air guide cylinder 1501 fixedly connected to the inner wall of the upper end of the fixed housing 2, a piston is slidably arranged in the air guide cylinder 1501, and the bottom end of the piston is fixedly connected to a transmission rod 1502 that slides through the bottom wall of the air guide cylinder 1501, an annular groove 17 is opened on the side wall of the high-voltage discharge needle 3, and a locking needle clamp 1503 for clamping in the annular groove 17 is fixedly connected to the bottom end of the transmission rod 1502, and the locking needle clamp 1503 is made of rubber material.

[0052] Reference Figure 6The pneumatic part 12 includes an airbag 1201 fixedly connected to the inner wall of the fixed housing 2. The airbag 1201 is connected to the upper end of the air guide tube 1501 through an air guide tube 1202. The air guide tube 1202 is a plastic hose. The airbag 1201 maintains a distance from the needle guide plate 7 when inflated. The distance is slightly larger than the thickness of the locking needle snap ring 1503. Before the needle guide plate 7 contacts the airbag 1201, the locking needle snap ring 1503 just detaches from the top of the needle guide plate 7. It is worth noting that the locking needle snap ring 1503 is located at the top of the needle guide plate 7 near the edge of the perforation 11, and the curvature of the inner arc surface of the locking needle snap ring 1503 matches the annular groove 17.

[0053] Reference Figure 5 A reset auxiliary plate 14 is fixedly connected to one side of the upper end of the locking needle clamp 1503, and an operation hole corresponding to the reset auxiliary plate 14 is opened at the bottom end of the fixed shell 2. The reset auxiliary plate 14 is located directly above the operation hole. When the high-voltage discharge needle 3 needs to be replaced in the later stage, the reset auxiliary plate 14 can be lifted up by an external auxiliary tool to end the locking of the high-voltage discharge needle 3.

[0054] The working principle of this embodiment is as follows: when the needle guide plate 7 moves away from the corresponding perforation 11, the needle guide plate 7 is about to contact the airbag 1201, and the locking needle snap ring 1503 is separated from the top of the needle guide plate 7. When the needle guide plate 7 continues to move and squeeze the airbag 1201, the gas inside the airbag 1201 will enter the air cylinder 1501 through the air guide tube 1202. After the gas enters the air cylinder 1501, it will squeeze the piston inside it to move downward, thereby pushing the locking needle snap ring 1503 to move vertically downward through the transmission rod 1502, and before the end of the high-voltage discharge needle 3 contacts the conductive sheet 13, the locking needle snap ring 1503 has been tightly attached to the circumferential surface of the high-voltage discharge needle 3 under the action of squeezing the airbag 1201. As the needle guide plate 7 further squeezes the airbag 1201, the squeezed airbag 1201 is compressed and deformed, but the locking needle snap ring 1503 remains motionless at this time. When the end of the high-voltage discharge needle 3 contacts the conductive sheet 13, at this time The annular groove 17 on the high-voltage discharge needle 3 just moves to above the locking needle snap ring 1503. At this time, the locking needle snap ring 1503 quickly enters the annular groove 17 under the action of the squeezing airbag 1201, completing the locking of the high-voltage discharge needle 3 (at this time, even if the personnel releases the rotating winding drum 801, the squeezing airbag 1201 tends to expand under the action of its own elasticity, but because the locking needle snap ring 1503 and the annular groove 17 form a clamping structure, the squeezing airbag 1201 will not move). After locking, the annular electromagnet 72 is powered off. It is worth noting that the traction main rope 802 will not rebound during the process of driving the traction branch rope 803 to pull the needle body guide plate 7 to move, that is, the winding drum 801 will not rotate during the operation, so that the airbag 1201 will not rebound, causing the gas in the air guide cylinder 1202 to be sucked into the bag 1201, so that the transmission rod 1502 continues to drive the locking needle snap ring 1503 to move downward and smoothly snap into the annular groove 17. By fixing the reset auxiliary plate 14 on one side of the upper end of the locking needle clamp 1503, the end of the reset auxiliary plate 14 extends to the top of the operating hole. When the high-voltage discharge needle 3 needs to be maintained and replaced later, the reset auxiliary plate 14 can be pushed up through the operating hole with the help of a tool, so that the locking needle clamp 1503 is pushed up, and the locking of the high-voltage discharge needle 3 is abandoned, so as to replace the high-voltage discharge needle 3. When the locking needle clamp 1503 is pushed up, the transmission rod 1502 moves upward. In the process of the transmission rod 1502 moving upward, the gas inside the air guide cylinder 1501 will be squeezed into the air bag 1201 through the air guide tube 1202. The expansion of the air bag 1201 will push the needle body guide plate 7 to move in the direction of the perforation 11, so as to facilitate the replacement of the high-voltage discharge needle 3. After the high-voltage discharge needle 3 is replaced, the above steps are repeated to lock the high-voltage discharge needle 3 again.

[0055] The above-mentioned specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
