Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage distribution cabinets, and specifically to a high and low voltage distribution cabinet with a protection function and its usage method. Background Art

[0002] High and low voltage distribution cabinets are power distribution equipment used in the power supply system for power distribution, control, metering, and connection of cables. Generally, power supply bureaus and substations use high-voltage switch cabinets, and then the low-voltage side is led out through a transformer step-down to the low-voltage distribution cabinet, and the low-voltage distribution cabinet is then connected to each power distribution panel, control box, and switch box of the electricity consumption. Inside, it is a device that assembles some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protection devices into one to meet the design function requirements.

[0003] For existing high and low voltage distribution cabinets, although they already have high protection technologies in terms of electrical safety, there are still drawbacks that need to be improved in actual use. For example:

[0004] High and low voltage distribution cabinets usually need to be operated and maintained by professional staff. However, especially in winter when the weather is dry, the human body will carry a large amount of static electricity, and static electricity poses a greater hidden danger to the distribution cabinet. If the distribution cabinet is directly touched, it is easy to cause static electricity discharge. Generally, items such as anti-static bracelets are easily forgotten to be carried, so the danger during the maintenance of the distribution cabinet is increased. At the same time, when the staff is maintaining the distribution cabinet and leaves briefly due to other matters, they usually do not close the cabinet door for convenience, which easily causes direct contact between external factors and internal equipment, increasing the hidden danger of danger;

[0005] Therefore, a high and low voltage distribution cabinet with a protection function is now designed to solve such defects. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a high and low voltage distribution cabinet with a protection function and its usage method, which solves the problem of relatively high safety hazards of existing distribution cabinets.

[0015] The present invention also discloses a usage method of a high and low voltage power distribution cabinet with a protection function, which specifically includes the following steps:

[0016] S1. Before use, when installing the power distribution cabinet body, first insert two conical cylinders into the ground and fix them, and then proceed to step S2;

[0017] S2. When in use and the protective door panel needs to be opened, first hold the static electricity bracelet with your hand and pull the second cable. While holding the static electricity bracelet with your hand, use the connection of the second cable, the blocking plate, the plug guide rod and the plug cylinder plug to conduct the static electricity on the body into the ground through the conical cylinder, so as to eliminate the static electricity on the body surface and improve the protection performance. Then continue to pull the second cable. When the second cable is pulled upward, it will drive the plug guide rod and the lifting plate to rise synchronously under the guidance of the bent conduit. The plug guide rod will be withdrawn from the inside of the plug cylinder plug and the positioning slot. At this time, the protective door panel is unlocked and loses its limit. At the same time, the lifting plate will use the lifting arc block to hook the arc surface pressure plate, and the sliding plate will drive the arc surface pressure plate to rise by the limit of the slider sleeve. After the sliding plate rises, it will be separated from the bent plate. At this time, the arc surface pressure plate loses the hooking limit of the bent plate. After the rising is completed, hang the static electricity bracelet at the bottom of the hook plate for fixation. Then hold the handle frame with your hand and pull the two protective door panels to turn and open to both sides. When the protective door panel turns, it will pull the first cable. After the first cable is pulled, it will drive the counterweight seat to rise under the limit of the vertical guide rod through the guidance of the first guide wheel, the second guide wheel, the inner groove ball and the guide ring. At the same time, when the counterweight seat rises, it will compress the first spring to store energy. When the protective door panel turns to 90 degrees, the positioning frame will be butted with the L-shaped pressure plate. Then stand on the top of the pedal and press down the pedal. After the pedal descends, it will drive the plug cylinder plug and the L-shaped pressure plate to descend. After the L-shaped pressure plate descends, it will insert into the inner side of the positioning frame to fix the protective door panel. During the process of the protective door panel turning and opening, the arc pressing block is no longer squeezed by the inner wall of the power distribution cabinet body. At this time, the fifth spring uses its elastic force to drive the arc surface pressure plate to move to both sides to complete the separation from the bent plate. Then operate the equipment inside the power distribution cabinet body;

[0018] S3. When waiting to complete work or temporarily leave the main body of the power distribution cabinet, if leaving from the top of the pedal, at this time, the second spring pushes the pedal and the L-shaped pressing plate to rise. After the L-shaped pressing plate rises, it no longer limits the positioning frame. At this time, the first spring pushes the counterweight seat to descend along the vertical guide rod. At this time, due to the interference fit and friction between the counterweight seat and the vertical guide rod, the counterweight seat can only be slowly pushed down by the first spring. After the counterweight seat descends, it uses the first cable to pull the protective door panel to slowly flip and re-close with the main body of the power distribution cabinet under the guidance of the guide ring, inner groove ball and the first guide wheel. When the protective door panel flips and resets, the arc-shaped pressing block is squeezed by the side wall of the inner cavity of the power distribution cabinet main body. At this time, the two arc-shaped pressing plates will move towards each other under the thrust of the arc-shaped pressing block. The arc ends of the arc-shaped pressing plates will squeeze the bent plate to drive the handle frame and the hook plate to move backward under the guidance of the transverse rod. Since the hook plate retracts into the retraction port, at this time, the static electricity bracelet is squeezed and detached from the surface of the hook plate. Then, the static electricity bracelet rises under the elastic force of the fourth spring and reconnects with the bent conduit. At the same time, the plug guide rod and the lifting plate also descend under the elastic force of the fourth spring. The plug guide rod is reinserted into the positioning slot and the plug cylinder plug. The lifting arc block descends and contacts the arc-shaped pressing plate and then flips without making hard contact with the arc-shaped pressing plate. Then, the lifting arc block is repositioned at the bottom of the arc-shaped pressing plate. At the same time, after the arc end of the arc-shaped pressing plate squeezes the bent plate, it will separate from the bent plate and complete the clamping. At this time, the handle frame extends out of the retraction port under the elastic force of the third spring for convenient use next time.

[0019] Beneficial effects

[0020] The present invention provides a high and low voltage power distribution cabinet with a protection function and its use method. Compared with the existing technology, it has the following beneficial effects:

[0021] (1). The high and low voltage power distribution cabinet with a protection function and its use method, by using the power distribution cabinet mechanism and the protection flipping mechanism in a combined manner, the settings of these two mechanisms can utilize the connection between the static electricity bracelet and the plug guide rod, making touching the static electricity bracelet a prerequisite for opening the protective door panel, thereby being able to pre-eliminate human static electricity. Then, the protective door panel is unlocked by the linkage between the structures, improving the safety during operation. And during the process of opening the protective door panel, the structure is reset through cooperation, enabling it to close in time after the staff leaves to protect the internal equipment, thus improving the safety protection.

[0022] (2). The high and low voltage power distribution cabinet with a protection function and its use method, by installing a side groove inside the plug cylinder plug and using the second cable, static electricity bracelet and hook plate in combination, the settings of these structures can make it necessary to manually pull the static electricity bracelet before operation to pull out the plug guide rod from the inside of the plug cylinder plug to unlock the protective door panel. And during this process, the static electricity of the human body can be directly conducted to the ground, thereby reducing the danger of static electricity discharge and improving the safety during operation.

[0023] (3) The high and low voltage power distribution cabinet with protection function and its usage method are such that a counterweight seat is installed inside the linkage groove by means of a vertical guide rod, and it is used in combination with a first cable and a pedal. The setting of these structures can, after the protection door panel is opened, enable the staff to stand on the top of the pedal and let the L-shaped pressing plate be clamped into the positioning frame to fix the protection door panel, thus facilitating subsequent operations. And if the staff briefly leaves the top of the pedal, the friction between the counterweight seat and the vertical guide rod can be utilized, and with the elastic force of the first spring, the first cable can be made to pull the protection door panel to flip and reset to close the power distribution cabinet body, preventing the internal equipment from being exposed to the outside for a long time and reducing potential safety hazards.

[0024] (4) The high and low voltage power distribution cabinet with protection function and its usage method are such that a lifting arc block is installed at the bottom end of the lifting plate, and it is used in combination with an arc surface pressing plate and a bent plate. The setting of these structures can, during the closing process of the protection door panel, enable the arc-shaped pressing block to be squeezed by the inner wall of the power distribution cabinet body, cause the arc surface pressing plate and the bent plate to drive the hook plate to retract, and make the static electricity bracelet rise and reset, thus ensuring that the subsequent staff can come back and contact the static electricity bracelet again for a new static electricity elimination step, ensuring the safety of the staff.

[0042] The present invention also discloses a usage method of a high and low voltage power distribution cabinet with a protection function, which specifically includes the following steps:

[0043] S1. Before use, when installing the power distribution cabinet body 101, first insert two conical cylinders 111 into the ground and fix them, and then proceed to step S2;

[0044] S2. When in use and it is necessary to open the protection door panel 201, first hold the static electricity bracelet 220 with the hand and pull the second cable 217. While holding the static electricity bracelet 220 with the hand, utilize the connection of the second cable 217, the blocking plate 213, the plug guide rod 212 and the plug cylinder plug 113 to conduct the static electricity on the body into the ground through the conical cylinder 111, thereby eliminating the static electricity on the body surface and improving the protection performance. Then continue to pull the second cable 217. When the second cable 217 continues to be pulled upwards, it will drive the plug guide rod 212 and the lifting plate 214 to rise synchronously under the guidance of the bent conduit 216. The plug guide rod 212 will be withdrawn from the inside of the plug cylinder plug 113 and the positioning slot 207. At this time, the protection door panel 201 is unlocked and loses its limit. At the same time, the lifting plate 214 will use the lifting arc block 215 to hook the arc surface pressing plate 221, and the sliding plate 211 will drive the arc surface pressing plate 221 to rise by the limit of the slider sleeve 223. After the sliding plate 211 rises, it will be separated from the bent plate 210. At this time, the arc surface pressing plate 221 loses the hooking limit of the bent plate 210. After the rising is completed, hang the static electricity bracelet 220 at the bottom of the hook plate 209 for fixation. Subsequently, hold the handle frame 208 with the hand and pull the two protection door panels 201 to flip open to both sides. When the protection door panel 201 flips, it will pull the first cable 109. After the first cable 109 is pulled, it will drive the counterweight seat 105 to rise under the limit of the vertical guide rod 104 through the guidance of the first guide wheel 117, the second guide wheel 118, the inner groove ball 108 and the guide ring 107. At the same time, the rising of the counterweight seat 105 will compress the first spring 106 for energy storage. When the protection door panel 201 flips to ninety degrees, the positioning frame 203 is docked with the L-shaped pressing plate 114. Then stand on the top of the pedal 116 with the foot and press down the pedal 116. After the pedal 116 descends, it will drive the plug cylinder plug 113 and the L-shaped pressing plate 114 to descend. After the L-shaped pressing plate 114 descends, it will insert into the inside of the positioning frame 203 to fix the protection door panel 201. During the process of the protection door panel 201 flipping open, the arc pressing block 225 is no longer squeezed by the inner wall of the power distribution cabinet body 101. At this time, the fifth spring 224 uses its elastic force to drive the arc surface pressing plate 221 to move to both sides and separate from the bent plate 210. Subsequently, operate the equipment inside the power distribution cabinet body 101;

[0045] S3. When the work to be completed or a temporary departure from the main body 101 of the power distribution cabinet is required, if leaving from the top of the pedal 116, at this time, the second spring 115 pushes the pedal 116 and the L-shaped pressing plate 114 to rise. After the L-shaped pressing plate 114 rises, it no longer limits the positioning frame 203. At this time, the first spring 106 pushes the counterweight seat 105 to descend along the vertical guide rod 104. Since there is an interference fit and friction between the counterweight seat 105 and the vertical guide rod 104, the counterweight seat 105 can only be slowly pushed down by the first spring 106. After the counterweight seat 105 descends, the first cable 109 pulls the protective door panel 201 to slowly flip and re-close with the main body 101 of the power distribution cabinet under the guidance of the guide ring 107, the inner groove ball 108 and the first guide wheel 117. When the protective door panel 201 flips and resets, the arc-shaped pressing block 225 is squeezed by the side wall of the inner cavity of the main body 101 of the power distribution cabinet. At this time, the arc-shaped pressing plates 221 on both sides will move towards each other under the thrust of the arc-shaped pressing block 225. The arc ends of the arc-shaped pressing plates 221 will squeeze the bent plate 210 to drive the handle holder 208 and the hook plate 209 to move backward under the guidance of the horizontal rod 204. Since the hook plate 209 retracts into the retraction port 202, at this time, the static electricity bracelet 220 is squeezed and detached from the surface of the hook plate 209. Then, the static electricity bracelet 220 rises under the elastic force of the fourth spring 218 and re-docks with the bent conduit 216. At the same time, the pin guide rod 212 and the lifting plate 214 also descend under the elastic force of the fourth spring 218. The pin guide rod 212 is re-inserted into the positioning slot 207 and the inner part of the plug cylinder plug 113. The lifting arc block 215 descends and contacts the arc-shaped pressing plate 221 and then flips without making hard contact with the arc-shaped pressing plate 221. Then, the lifting arc block 215 is re-located at the bottom of the arc-shaped pressing plate 221. At the same time, after the arc end of the arc-shaped pressing plate 221 squeezes the bent plate 210, it will separate from the bent plate 210 and complete the clamping. At this time, the handle holder 208 extends out of the retraction port 202 again under the elastic force of the third spring 206 for convenient use next time.

9. A method for using a high and low voltage distribution cabinet with protection function, characterized in that: The specific steps include: S1. Before use, when installing the power distribution cabinet body (101), first insert the two conical cylinders (111) into the ground and fix them, and then go to step S2; S2. When the protective door panel (201) needs to be opened during use, the user first holds the anti-static bracelet (220) with the hand and pulls the second pull rope (217). While holding the anti-static bracelet (220), the user uses the connection between the second pull rope (217), the blocking plate (213), the latch guide rod (212) and the plug plug (113) to guide the static electricity of the body into the ground using the conical tube (111), thereby eliminating the static electricity on the surface of the body and improving the protectiveness. The user then continues to pull the second pull rope (217). When the second pull rope (217) continues to be pulled upward, the latch guide rod (212) and the lifting plate (214) are pulled together under the guidance of the curved guide tube (216). The locking plate (210) is lifted up and the locking plate (211) is lifted up and the locking plate (210 ... Then, the handle frame (208) is held by hand and the two protective door panels (201) are pulled to flip open to both sides. When the protective door panels (201) are flipped, the first cable (109) is pulled. After the first cable (109) is pulled, it is guided by the first guide wheel (117), the second guide wheel (118), the inner groove ball (108) and the guide ring (107), and the counterweight seat (105) is pulled up in the limit position of the vertical guide rod (104). At the same time, the rise of the counterweight seat (105) compresses the first spring (106) to store force. When the protective door panel (201) is flipped to 90 degrees, the positioning frame (203) is docked with the L-shaped pressure plate (114), and then Then, the user stands on the top of the pedal (116) with his foot to press the pedal (116) downward. When the pedal (116) is lowered, it drives the plug (113) and the L-shaped pressing plate (114) to be lowered. When the L-shaped pressing plate (114) is lowered, it is inserted into the inner side of the positioning frame (203) to fix the protective door plate (201). When the protective door plate (201) is turned over and opened, the arc pressing block (225) is no longer squeezed by the inner wall of the power distribution cabinet body (101). At this time, the fifth spring (224) uses elastic force to drive the arc pressing plate (221) to move to both sides and separate from the curved plate (210), and then the equipment inside the power distribution cabinet body (101) is operated. S3, when the work is completed or it is necessary to temporarily leave the power distribution cabinet body (101), if you leave from the top of the pedal (116), the second spring (115) pushes the pedal (116) and the L-shaped pressure plate (114) to rise, and the L-shaped pressure plate (114) no longer limits the positioning frame (203) after rising. At this time, the first spring (106) pushes the counterweight seat (105) to descend along the vertical guide rod (104). At this time, due to the interference fit between the counterweight seat (105) and the vertical guide rod (104), there is friction, so the counterweight seat (105) can only be moved by the first spring (106). The spring (106) pushes the counterweight seat (105) to slowly descend. At this time, after the counterweight seat (105) descends, the first cable (109) is used to pull the protective door plate (201) under the guidance of the guide ring (107), the inner groove ball (108) and the first guide wheel (117) to slowly turn over and close with the power distribution cabinet body (101). When the protective door plate (201) turns over and resets, the arc pressure block (225) is squeezed by the side wall of the inner cavity of the power distribution cabinet body (101). At this time, the arc pressure plates (221) on both sides will move towards each other under the thrust of the arc pressure block (225). The arc pressure plates (221) The arc end of 1) will squeeze the curved plate (210) to drive the handle frame (208) and the hook plate (209) to move backward under the guidance of the transverse rod (204). Since the hook plate (209) is retracted into the retraction opening (202), the electrostatic wristband (220) is squeezed and detached from the surface of the hook plate (209). Then, the electrostatic wristband (220) rises under the elastic force of the fourth spring (218) and reconnects with the curved guide tube (216). At the same time, the latch guide rod (212) and the lifting plate (214) also descend under the elastic force of the fourth spring (218). 2) Reinsert the positioning slot (207) and the insert plug (113), and the lifting arc block (215) descends to contact the arc pressure plate (221) and then flips over without hard contact with the arc pressure plate (221), and then the lifting arc block (215) is re-located to the bottom of the arc pressure plate (221). At the same time, the arc end of the arc pressure plate (221) squeezes the bent plate (210) and separates from the bent plate (210) and completes the clamping. At this time, the handle frame (208) is re-extended from the retraction opening (202) under the elastic force of the third spring (206) to facilitate the next use.
