Description

Technical Field

[0001] This invention relates to the field of discharge rod technology, and in particular to an intelligent telescopic and convenient high-voltage discharge rod. Background Technology

[0002] High-voltage discharge rods are indispensable tools for the commissioning and maintenance of high-voltage pulse modulators. The working principle of a high-voltage discharge rod is to first discharge through a discharge conductor, and then discharge again through a grounding lead, thereby completely discharging the energy storage elements of the equipment. Currently, the main structure of a high-voltage discharge rod consists of an insulating rod with a discharge hook and a grounded solid conductor installed on it, typically placed inside the high-voltage pulse modulator for discharge.

[0003] Existing telescopic discharge rods are all manually adjusted by knobs located at the inner and outer rods. When facing dischargers at a high position (the height of which is difficult to judge), it is not easy to adapt the telescopic length of the discharge rod to the desired length in one go. It is necessary to repeatedly extend and retract the rod to try and find the right length. However, because the adjustment knob is located at the connection between the inner and outer rods and is a certain distance from the handle, repeated adjustments require constantly bringing the discharge hook closer to the discharger to try (adjust once, try once), which is very inconvenient.

[0004] Therefore, to address the above issues, a discharge rod with an adjustment mechanism integrated into the handle can be designed, which makes adjustment more convenient and intelligent without compromising discharge safety. Summary of the Invention

[0005] To overcome the problem that existing telescopic discharge rods are difficult to adjust the length of the discharge rod at high locations in one go, this invention provides an intelligent telescopic and convenient high-voltage discharge rod. The invention controls the inflation and deflation of the airbag cover through the adjustment component at the handle end, realizing the rapid extension and retraction of the inner rod body. This avoids the tedious operation of traditional manual knob adjustment that requires repeated attempts, and is especially suitable for the precise positioning of discharge rods at high locations.

[0006] This invention is achieved through the following technical solution: This invention provides an intelligent telescopic and convenient high-voltage discharge rod, comprising a handle, an outer rod detachably mounted on one end of the handle, an inner rod movably connected to the outer rod, a discharge resistor detachably mounted on the inner rod, a discharge hook fixedly connected to one end of the discharge resistor, and a grounding wire connected to the other end of the discharge resistor. The handle contains an air chamber, and an elastic pull rope connects the handle to the inner rod. A ring-shaped airbag is detachably mounted on the handle, with its inflated end contacting the inner rod and communicating with the air chamber. Both the airbag and the air chamber are filled with inert gas. An adjustment component is rotatably connected to the other end of the handle, and a linkage component connected to the output end of the adjustment component is installed inside the handle. The adjustment component drives the linkage component to move within the air chamber. When the linkage component moves, inert gas flows between the airbag and the air chamber. When inert gas flows into the airbag, the airbag inflates and pushes the inner rod out of the outer rod. When inert gas flows out of the airbag, the airbag contracts, and the elastic pull rope pulls the inner rod back to the outer rod.

[0007] As one aspect of the present invention, the handle includes a grip portion, an upper edge platform and a lower edge platform integrally fixedly connected to the upper and lower ends of the grip portion, an air passage opened in the grip portion, and a lower hook installed on the upper end of the upper edge platform. An adjustment component is rotatably connected to the lower edge platform, and one end of the air passage is connected to the air chamber. The inner rod includes an inner insulating rod movably connected to the outer rod, a groove opened at the lower end of the inner insulating rod, and an elastic connector installed at the lower end of the inner insulating rod. One end of the elastic pull rope is connected to the lower hook, and the other end is connected to the elastic connector. An air inlet head is fixedly connected to the lower end of the airbag cover, and a shaping ring is fixedly connected to the upper end. The air inlet head is engaged in the air passage, and the shaping ring is engaged in the groove.

[0008] As one embodiment of the present invention, the elastic connector includes a sliding sleeve fixedly installed at the lower end of the inner insulating rod, an upper hook movably connected in the sliding sleeve, and a spring plate fixedly connected between the upper hook and the sliding sleeve. The other end of the elastic pull rope is connected to the upper hook. The elastic modulus of the elastic pull rope is less than the elastic modulus of the spring plate.

[0009] As one aspect of the present invention, the handle further includes a bayonet formed in the upper edge; the outer rod includes an outer insulating rod, a wedge fixedly connected to the lower edge of the outer insulating rod, and a guide groove formed on the inner wall of the outer insulating rod, the lower end of the guide groove being open and the upper end being closed, and the wedge being able to engage in the corresponding bayonet; the inner rod also includes a guide block fixedly connected to the lower edge of the inner insulating rod, and the guide block being slidably connected in the guide groove.

[0010] As one aspect of the present invention, the adjusting assembly includes a turntable rotatably connected to the lower edge platform, a handle fixedly connected to the lower end of the turntable, and a lead screw fixedly connected to the turntable. The rotation centers of the turntable, the handle, and the lead screw are coaxial and on the same straight line as the central axis of the outer rod. The linkage assembly includes a rubber plug movably connected to the air chamber, a return spring installed between the lower end of the rubber plug and the bottom wall of the air chamber, a connecting rod connected to the lower end of the rubber plug, and a threaded sleeve connected to the lower end of the connecting rod. The threaded sleeve is threadedly connected to the lead screw. When the lead screw rotates, the threaded sleeve can move vertically along the central axis of the lead screw.

[0011] As one aspect of the present invention, a ring of scale markings is provided on the surface of the lower edge platform, and a pointer is fixedly connected to the edge of the turntable, with the scale markings located on the rotation path of the pointer.

[0012] As one aspect of the present invention, an observation window is installed on the outer wall of the lower part of the outer insulating rod, and a color mark is provided on the outer wall of the lower part of the inner insulating rod. When the air pressure inside the airbag drops to the threshold F2, the inner insulating rod moves downward until the color mark and the observation window are on the same horizontal plane.

[0013] As one embodiment of the present invention, an anti-reverse assembly is installed on the handle, and an movable hole is provided on the handle. An anti-reverse hook is installed at the lower end of the anti-reverse assembly. A ratchet groove is provided on the adjusting assembly, and the anti-reverse hook is located on the rotation path of the ratchet groove. The central angle of the ratchet groove is α, 200° < α < 360°. Several ratchet steps are arranged in a circumferential array inside the ratchet groove. Each ratchet step has a straight wall on one side and an inclined wall on the other side. Limiting platforms are provided at both ends of the ratchet groove. When the adjusting assembly rotates clockwise, the inert gas in the air chamber flows into the airbag cover. When the adjusting assembly rotates counterclockwise, the inert gas in the airbag cover flows into the air chamber. When the adjusting assembly rotates clockwise, the anti-reverse hook passes through the inclined wall and the straight wall of the same ratchet step in sequence. When the anti-reverse hook enters between two adjacent ratchet steps, it is used to limit the rotation of the adjusting assembly in the counterclockwise direction.

[0014] As one aspect of the present invention, the anti-reverse assembly includes a movable rod movably connected in the movable hole and a follower spring connected to the movable rod, and an anti-reverse hook plate fixedly connected to the lower end of the movable rod; when the adjusting assembly rotates clockwise, the anti-reverse hook plate moves up and down through the follower spring.

[0015] As one embodiment of the present invention, an extension of insulating material is fixedly connected to the upper end of the inner insulating rod. The extension is parallel to the discharge resistor. A Hall sensor is installed inside the extension. The Hall sensor is used to sense the change in the electromagnetic field of the discharge resistor and send a signal to the control unit of the anti-reverse assembly. The anti-reverse assembly includes a drive motor mounted on the adjustment assembly and a slide rod mounted on the output end of the drive motor. The slide rod is a two-section sliding sleeve rod. A follower spring is fixedly connected between the two sleeve rods. One sleeve rod is connected to the output end of the drive motor. The anti-reverse hook plate is fixedly connected to the other sleeve rod. The drive motor is used to drive the anti-reverse hook plate in and out of the ratchet groove. When the adjustment assembly rotates clockwise, the anti-reverse hook plate moves up and down through the follower spring.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This invention controls the inflation and deflation of the airbag cover through the adjustment component at the handle end, realizing the rapid extension and retraction of the inner rod body. This avoids the tedious operation of traditional manual knob adjustment that requires repeated attempts, and is especially suitable for the precise positioning of high-altitude discharge devices. At the same time, the scale markings and pointer work together to intuitively display the extension and retraction length of the inner rod body, making it easy for users to adjust it to the correct height of the discharge device in one go. 2. This invention fills the airbag and air chamber with inert gas, which can isolate oxygen and moisture, prevent arc ignition or insulation performance degradation. At the same time, since the airbag can be made of insulating materials such as silicone / fluororubber, it can ensure safe operation under high pressure. The airbag of this invention adopts a bellows-style folding structure, with a ring skeleton supporting the folds to ensure the stability of axial expansion and contraction and avoid sealing failure caused by lateral deformation. 3. The anti-retraction component of this invention restricts the counterclockwise rotation of the adjustment component to prevent the inner rod from accidentally retracting after the discharge hook is connected to the discharger, thus avoiding damage to the discharger; the outer rod and the handle are detachably connected by a wedge-lock, and vulnerable parts such as the elastic pull rope and airbag cover can be replaced independently, reducing maintenance costs. 4. In this invention, the handle of the adjustment component is designed to be elliptical, which conforms to the human grip habit; the preferred ratchet groove central angle α=270° has been verified by experiments to conform to the natural bending angle of the operator's wrist, reducing fatigue during long-term operation; at the same time, this invention achieves intelligent automatic locking of the discharge process by combining the Hall sensor and the drive motor, reducing manual intervention and making it suitable for remote operation in high-altitude or dangerous environments.

[0028] Please see Figures 1-15This application provides an intelligent telescopic and convenient high-voltage discharge rod, comprising a handle 1, an outer rod 2 detachably mounted on one end of the handle 1, an inner rod 3 movably connected within the outer rod 2, a discharge resistor 4 detachably mounted on the inner rod 3 (which can actually be threaded for easy and quick assembly and disassembly), a discharge hook 5 fixedly connected to one end of the discharge resistor 4, and a grounding wire 6 connected to the other end of the discharge resistor 4. An air chamber 107 is provided inside the handle 1, and an elastic pull rope 9 connects the handle 1 and the inner rod 3. An annular airbag cover 10 is detachably mounted on the handle 1, and the inflated end of the airbag cover 10 contacts the inner rod 3. The airbag cover 10 is connected to the air chamber 107, and both the airbag cover 10 and the air chamber 107 are filled with inert gas. The other end of the handle 1 is rotatably connected to the adjustment component 7. The handle 1 is equipped with a linkage component 8 connected to the output end of the adjustment component 7. The adjustment component 7 is used to drive the linkage component 8 to move in the air chamber 107. When the linkage component 8 moves, the inert gas flows between the airbag cover 10 and the air chamber 107. When the inert gas flows into the airbag cover 10, the airbag cover 10 expands and pushes the inner rod 3 to extend out of the outer rod 2. When the inert gas flows out of the airbag cover 10, the airbag cover 10 contracts, and the elastic pull rope 9 pulls the inner rod 3 back to the outer rod 2. The airbag cover 10 (which has a ring-shaped accordion-style hinge structure with a ring-shaped frame for support at the hinges, and only axial expansion and contraction during inflation and deflation) is in a pre-inflated state. With the inner rod 3 fully retracted into the outer rod 2, the airbag cover 10 maintains a certain air pressure, providing upward support for the inner rod 3 and forcing the elastic cord 9 to be in a stretched state. The elastic support force of the airbag cover 10 (the pressure F1 of the inert gas) and the elastic tension of the elastic cord 9 are balanced. The linkage component 8 is controlled by the adjustment component 7 at the handle 1 within the air chamber 107. The airbag 10 is inflated or deflated by movement. During inflation, the airbag 10 expands and elongates, pushing the inner rod outwards and extending the discharge rod. During deflation, the airbag 10 contracts, and the elastic cord 9 pulls the inner rod back, shortening the discharge rod. In practical applications, nitrogen or argon can be used as the inert gas to maintain a high degree of insulation within the discharge rod. Similarly, the airbag 10 must be made of insulating materials such as silicone or fluororubber. The pre-inflation pressure of the airbag 10 (the amount of inert gas) and the elastic modulus design of the elastic cord 9 (material, thickness, etc.) are calibrated experimentally before assembly. Compared to simple pneumatic or hydraulic devices, the design using the airbag 10's lifting control for extension and retraction has lower requirements for structural sealing, lower manufacturing costs, and, due to the insulating properties of the inert gas and the airbag 10 material itself, offers higher safety.

[0029] Please see Figures 1-4 , Figures 6-9 and Figures 11-15In this embodiment, the handle 1 includes a grip portion 101, an upper edge platform 102 and a lower edge platform 103 integrally fixedly connected to the upper and lower ends of the grip portion 101, an air passage 108 opened in the grip portion 101, and a lower hook 106 installed on the upper end of the upper edge platform 102. The adjustment component 7 is rotatably connected to the lower edge platform 103. One end of the air passage 108 communicates with the air chamber 107. The inner rod 3 includes an inner insulating rod 301 movably connected to the outer rod 2, a groove 306 opened on the lower end of the inner insulating rod 301, and an elastic connector installed on the lower end of the inner insulating rod 301. One end of the elastic pull rope 9 is connected to the lower hook 106, and the other end... Connected to a flexible connector; an air inlet 1001 is fixedly connected to the lower end of the airbag cover 10, and a shaping ring 1002 is fixedly connected to the upper end. The air inlet 1001 is snapped into the air passage 108 (in actual applications, a reasonable sealing structure is adopted at the junction of the air inlet 1001 and the air passage 108, or sealant is used to seal it to prevent air leakage). The shaping ring 1002 is snapped into the groove 306 (the shaping ring 1002 is made of insulating material with high hardness and rigidity, and forms a snap with the groove 306 on the inner rod body 3, so that the airbag cover 10 is not easy to fall off during assembly, and the airbag cover 10 will not detach from the inner rod body 3 during use). The elastic connector includes a sliding sleeve 302 fixedly installed at the lower end of the inner insulating rod 301, an upper hook 303 movably connected in the sliding sleeve 302, and a spring plate 304 fixedly connected between the upper hook 303 and the sliding sleeve 302. The other end of the elastic pull rope 9 is connected to the upper hook 303. The elastic modulus of the elastic pull rope 9 is less than the elastic modulus of the spring plate 304. The handle 1 also includes a bayonet 105 formed in the upper edge 102; the outer rod 2 includes an outer insulating rod 201, a wedge 202 fixedly connected to the lower edge of the outer insulating rod 201, and a guide groove 203 formed on the inner wall of the outer insulating rod 201. The lower end of the guide groove 203 is open and the upper end is closed. The wedge 202 can be engaged in the corresponding bayonet 105 (in this embodiment, the outer rod 2 and the handle 1 are assembled by using a wedge 202 with a certain elasticity to engage with the bayonet 105, which is convenient for installation and disassembly. After disassembly, it is also convenient to install and replace the internal airbag cover 10 and elastic pull rope 9); the inner rod 3 also includes a guide block 305 fixedly connected to the lower edge of the inner insulating rod 301. The guide block 305 is slidably connected in the guide groove 203. In practical applications, the elastic connector can be selectively installed and used. Its purpose is to make the upper hook 303 a telescopic structure, which is convenient for bolting connection with the elastic pull rope 9. It is worth noting that if the elastic connector is selected, the elastic modulus of the spring plate 304 should be greater than the elastic modulus of the elastic pull rope 9. When the inner rod 3 extends, the elastic deformation of the elastic pull rope 9 is utilized first.

[0030] Please see Figures 1-4 and Figures 10-12In this embodiment, the adjustment component 7 includes a turntable 701 rotatably connected to the lower edge platform 103, a handle 702 fixedly connected to the lower end of the turntable 701, and a lead screw 703 fixedly connected to the turntable 701. The rotation centers of the turntable 701, handle 702, and lead screw 703 are coaxial and on the same straight line as the central axis of the outer rod body 2. The linkage component 8 includes a rubber plug 801 movably connected to the air chamber 107, a return spring 802 installed between the lower end of the rubber plug 801 and the bottom wall of the air chamber 107, a connecting rod 803 connected to the lower end of the rubber plug 801, and a threaded sleeve 804 connected to the lower end of the connecting rod 803. The threaded sleeve 804 is threadedly connected to the lead screw 703. When the lead screw 703 rotates, the threaded sleeve 804 can move vertically along the central axis of the lead screw 703. In this embodiment, the handle 702 is designed in an elliptical shape, which makes it easier for users to grip and apply force. Rotating the handle 702 and the turntable 701 will drive the threaded sleeve 804 to move through the lead screw 703, thereby allowing the rubber stopper 801 to move in the air chamber 107, causing inert gas to flow into the airbag cover 10 (rotating clockwise, the rubber stopper 801 moves upward), and inert gas to flow from the airbag cover 10 into the air chamber 107 (rotating counterclockwise, the rubber stopper 801 moves downward).

[0031] Please see Figures 1-4 and Figures 9-10 In this embodiment, a scale mark 104 is provided on the surface of the lower edge platform 103, and a pointer 704 is fixedly connected to the edge of the turntable 701. The scale mark 104 is located on the rotation path of the pointer 704. The rotation angle of the turntable 701 is converted into the extension and retraction length of the inner rod 3 for display through the scale mark 104 (in practical applications, two sets of scale marks 104 can be made at the same time, corresponding to the rotation angle of the turntable 701 and the extension and retraction length of the inner rod 3 or the length of the entire discharge rod at the corresponding angle). When the discharge rod is extended and retracted for adjustment, the distance between the discharger and the operator can be measured, making the function more versatile.

[0032] Please see Figure 2 and Figures 6-7In this embodiment, an observation window 204 is installed on the outer wall of the lower part of the outer insulating rod 201, and a color mark 307 is provided on the outer wall of the lower part of the inner insulating rod 301. When the air pressure inside the airbag cover 10 drops to the threshold F2, the inner insulating rod 301 moves downward until the color mark 307 and the observation window 204 are on the same horizontal plane. This embodiment actually designs a mechanized intelligent alarm mechanism. As mentioned above, when the inner rod 3 is fully retracted into the outer rod 2, the airbag cover 10 maintains a pressure of F1. At this time, the elastic pull rope 9 is in an extended state. When the airbag cover 10 ages or leaks, the air pressure inside the airbag cover 10 will drop (F2), and air may enter, reducing the concentration of inert gas, lowering insulation, and affecting safety. At this time, the pulling force of the elastic pull rope 9 will be greater than the pressure of the airbag cover 10, causing the inner rod 3 to move further down, so that the position of the color mark 307 moves down to the observation window 204. Because the observation window 204 is transparent, the user can observe the color mark 307, which indicates that the airbag cover 10 is leaking and needs maintenance (under normal circumstances, the pressure of the airbag cover 10 is maintained at F1, and the color mark 307 is above the observation window 204 and cannot be seen by the user).

[0033] Please see Figures 1-4 , Figures 9-11 and Figures 15-17In this embodiment, an anti-reverse assembly 11 is installed on the handle 1, and an active hole 109 is provided on the handle 1. An anti-reverse hook 1103 is installed at the lower end of the anti-reverse assembly 11. A ratchet groove 705 is provided on the adjusting assembly 7, and the anti-reverse hook 1103 is located on the rotation path of the ratchet groove 705. The central angle of the ratchet groove 705 is α, 200° < α < 360° (after testing, the rotation angle of the adjusting assembly 7 is between 200° < α < 360°, preferably 270°, which is more ergonomic). The ratchet groove 705 has a circumferential array of several... The ratchet platform has a structure with a straight wall on one side and an inclined wall on the other side. Both ends of the ratchet groove 705 are provided with limiting platforms. When the adjusting component 7 rotates clockwise, the inert gas in the air chamber 107 flows into the airbag cover 10. When the adjusting component 7 rotates counterclockwise, the inert gas in the airbag cover 10 flows into the air chamber 107. When the adjusting component 7 rotates clockwise, the anti-reverse hook 1103 passes through the inclined wall and the straight wall of the same ratchet platform in sequence. When the anti-reverse hook 1103 enters between two adjacent ratchet platforms, it is used to limit the adjustment component 7 from rotating counterclockwise. The design of the anti-reverse assembly 11 and the ratchet groove 705 is actually similar to the existing ratchet locking structure. Through the ratchet structure, the ratchet groove 705 can only pass through the anti-reverse hook 1103 clockwise. Once it rotates counterclockwise, it is locked by the limiting effect of the anti-reverse hook 1103 and the straight wall of the ratchet. This prevents the inner rod 3 from retracting due to the accidental counterclockwise rotation of the adjusting assembly 7 after the discharge hook 5 is connected to the discharger (which would generate a pulling force on the discharger and easily damage it).

[0034] Please see Figures 1-4 , Figures 9-11 and Figure 15 In this embodiment, the anti-reverse assembly 11 includes a movable rod 1101 movably connected within the movable hole 109 and a follower spring 1102 connected to the movable rod 1101. An anti-reverse hook 1103 is fixedly connected to the lower end of the movable rod 1101. When the adjusting assembly 7 rotates clockwise, the anti-reverse hook 1103 moves up and down via the follower spring 1102. Both the movable rod 1101 and the anti-reverse hook 1103 are made of insulating material. The upper end of the movable rod 1101 is fixed within the movable hole 109 by an axial limiting ring, allowing it to move up and down in the vertical direction (the stroke range is consistent with the depth of the ratchet groove 705), but preventing lateral deviation. The spring preload is designed to ensure that the anti-reverse hook 1103 is always in contact with the inclined wall of the ratchet groove 705 when no external force is applied.

[0035] Based on another embodiment of the anti-rollback component 11, please refer to Figures 16-17In this embodiment, an extension of insulating material is fixedly connected to the upper end of the inner insulating rod 301. The extension is parallel to the discharge resistor 4. A Hall sensor 12 is installed inside the extension. The Hall sensor 12 is used to sense the change in the electromagnetic field of the discharge resistor 4 and send a signal to the control unit of the anti-reverse assembly 11. The anti-reverse assembly 11 includes a drive motor 1104 mounted on the adjustment assembly 7 and a slide rod 1105 mounted on the output end of the drive motor 1104. The slide rod 1105 is a two-section sleeve rod that slides against each other. A follower spring 1106 is fixedly connected between the two sleeve rods. One of the sleeve rods is connected to the output end of the drive motor 1104. The anti-reverse hook 1103 is fixedly connected to the other sleeve rod. The drive motor 1104 is used to drive the anti-reverse hook 1103 to enter and exit the ratchet groove 705. When the adjustment assembly 7 rotates clockwise, the anti-reverse hook 1103 moves up and down through the follower spring 1106. When the discharge hook 5 is connected to the discharger, current flows through the discharge resistor 4. After the Hall sensor 12 detects the change in electromagnetic field, it can send a signal to the drive motor 1104 via a wireless module. The drive motor 1104 can be a cylinder or other similar device. The extension is a cylindrical insulator (material consistent with the inner rod 3). Its lower end is fixedly connected to the inner insulating rod 301, and its upper end extends to the vicinity of the discharge resistor 4. The detection surface of the Hall sensor 12 faces the discharge resistor 4 and is used to detect the axial magnetic field strength generated by the current in the discharge resistor 4 in real time. The Hall sensor 12 outputs a voltage signal, the drive motor 1104 starts, and synchronously controls the anti-retraction hook 1103 to enter the ratchet groove 705 to prevent the adjustment component 7 from retracting counterclockwise.

[0036] Working principle: The user holds the handle 1 with one hand, then points one end of the discharge hook 5 toward the discharger at the high position, and then rotates the adjustment component 7 clockwise to move the linkage component 8 in the air chamber 107. The inert gas in the air chamber 107 flows into the airbag cover 10, and the airbag cover 10 expands and elongates upward, pushing the inner rod 3 out of the outer rod 2, causing the discharge hook 5 to continuously approach the discharger until it is connected to the discharger. The charge of the discharger flows away through the discharge resistor 4 and the grounding wire 6.

[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
