Description

Technical Field

[0001] This utility model relates to the field of ring main unit technology, specifically a ring main unit that is easy to transport. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a modular ring main power supply unit. Its core components are load switches and fuses. It has advantages such as simple structure, small size, low price, and the ability to improve power supply parameters and performance as well as power supply safety. The outer shell of the power ring main unit is relatively large, and corresponding auxiliary equipment is required during installation to ensure the support and stability of the power ring main unit.

[0003] Publication No. CN220874081U discloses a power ring main unit that is easy to install. This device connects to the base via a first threaded hole on the vertical plate, ensuring the horizontal plate and the bottom surface of the self-locking casters are level, forming a common support. Anti-slip spikes enhance stability. For unpaved surfaces, it can be further bolted to the ground for even better stability. When the entire unit needs to be moved, the first threaded hole on the vertical plate is switched to the lower position, making the horizontal plate higher than the self-locking casters. In this case, the casters provide independent support, facilitating movement. However, this patent still has the following problems in practical use:

[0004] The device is fixed to the ground by a fixed device and supported by casters, which effectively improves stability. The fixed device can be adjusted up and down, which facilitates the movement and fixation of the ring main unit. However, the device requires the constant adjustment of multiple sets of bolts when adjusting the wheels, which greatly reduces the efficiency of the device and causes inconvenience to the staff when using it.

[0005] A ring main unit that is easy to transport is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a ring main unit that is easy to transport, in order to solve the problem mentioned in the background art. Currently, the current method of fixing the ring main unit to the ground with a fixing device and supporting it with casters can effectively improve stability and the fixing device can be adjusted up and down to facilitate the movement and fixing of the ring main unit. However, the device requires the constant adjustment of multiple sets of bolts when adjusting the wheels, which greatly reduces the efficiency of the device and causes inconvenience to the staff when using it.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ring main unit that is easy to transport, comprising a cabinet body, a base at the bottom of the cabinet body, and baffles symmetrically arranged at the top of the base, with a rain shield installed between the tops of the baffles; a moving mechanism is symmetrically arranged inside both ends of the base, and a limit component is provided inside the moving mechanism.

[0008] The moving mechanism includes a support box, which is symmetrically installed inside both ends of the base. A fixed box is installed at the top of the support box, and a screw is rotatably connected between the fixed box and the support box. A moving plate is threadedly connected to the outer side of the screw, and a wheel is installed at the bottom of the moving plate. A drive rod is rotatably connected between the fixed box and the baffle. A first rotating tooth is installed on the outer side of the drive rod, and a second rotating tooth is installed at the top of the screw. A sprocket is installed on the outer side of the drive rod, and a chain is meshed between the outer sides of the sprockets.

[0009] Preferably, the inner side of the support box is symmetrically provided with limiting grooves, and the two ends of the moving plate are symmetrically installed with limiting blocks, and one end of the limiting block is slidably connected inside the limiting groove.

[0010] Preferably, the bottom of the support box is symmetrically fitted with fixing sleeves on both sides, and the fixing sleeves are fitted with insert rods, and the insert rods and fixing sleeves are symmetrically threaded with bolts.

[0011] Preferably, the limiting component includes a fixed frame symmetrically installed on one side of the bottom end of the baffle, and a U-shaped rod is slidably connected inside the top of the fixed frame, and a connecting plate is installed between the bottom ends of the U-shaped rod. A fixed tube is installed inside the top of the fixed frame, and a sliding rod is slidably connected inside the fixed tube. A retraction spring is sleeved on the outside of the sliding rod. Sliding sleeves are symmetrically installed on both sides of the fixed tube. The two ends of the U-shaped rod pass through the sliding sleeves and are slidably connected to the sliding sleeves. A circular plate is installed on the outside of one end of the drive rod, and insertion holes are opened on the outside of the circular plate. Insertion blocks are symmetrically installed at the bottom end of the connecting plate, and the insertion blocks are inserted into the insertion holes.

[0012] Preferably, a handle is installed at one end of the drive rod.

[0013] Preferably, the bottom end of the slide rod is fixedly connected to the connecting plate.

[0014] Preferably, the first rotating tooth and the second rotating tooth are meshed together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This ring main unit is easy to transport, and its specific contents are as follows: By rotating two sets of drive rods, the operator drives the first rotating gear to rotate, which in turn drives the second rotating gear to rotate. The rotation of the screw drives the moving plate to move up and down inside the support box. Through the cooperation between the sprocket and the chain, the four drive rods rotate synchronously in the same direction. At this time, the four wheels move down at the same time, lifting the base, thereby achieving the effect of quickly adjusting the cabinet for movement. This is more convenient than the existing technology that requires constantly adjusting multiple sets of bolts, thus greatly improving the flexibility of the cabinet when used outdoors and providing a more convenient working environment. This design provides convenience for operators. By pulling the U-shaped rod and sliding it inside the top of the fixed frame, the movement of the U-shaped rod causes the connecting plate to move, which in turn causes the sliding rod to slide inside the fixed tube. At this point, the compression spring contracts, and the two ends of the U-shaped rod slide inside the sliding sleeve. The compression spring then quickly extends and resets, allowing the two sets of inserts to engage with the insertion holes. This achieves the effect of fixing and limiting the circular plate, thus quickly fixing and limiting the drive rod. This effectively prevents external forces from colliding with the drive rod and causing the screw to rotate out of place, resulting in more stable use of the adjusted wheel.

[0016] 1. By having the operator rotate two sets of drive rods, the first rotating gear rotates, which in turn rotates the second rotating gear. The second rotating gear then rotates the screw, causing the movable plate to move up and down inside the support box. The downward movement of the movable plate moves the wheels. Simultaneously, the rotation of the drive rods drives the rotation of two sets of sprockets. Through the cooperation between the sprockets and the chain, all four drive rods rotate synchronously in the same direction. At this point, all four wheels simultaneously move downwards, lifting the base. The operator then pushes the cabinet to move it, thus achieving the effect of quickly adjusting and moving the cabinet. This is significantly different from existing technologies that require constantly adjusting multiple sets of bolts. The method is more convenient, which greatly improves the flexibility of the cabinet when used outdoors and brings convenience to the staff. When the two sets of drive rods rotate in opposite directions, the moving plate moves up and drives the wheels to retract into the support box. At this time, the bottom of the support box is in contact with the ground, and the bottom of the plug rod is inserted into the ground, thus achieving the effect of quick installation of the cabinet outdoors. Using the plug rod to insert into the ground makes the cabinet installation more stable, greatly improving the efficiency of the device and bringing convenience to the staff. The movement of the moving plate drives the movement of the two sets of limit blocks. At this time, the two sets of limit blocks slide inside the limit groove, thus making the movement of the moving plate more stable.

[0017] 2. When the worker pulls the U-shaped rod and slides it inside the top of the fixed frame, the movement of the U-shaped rod causes the connecting plate to move, which in turn causes the sliding rod to slide inside the fixed tube. At this time, the compression spring contracts, and the two ends of the U-shaped rod slide inside the sliding sleeve. When the worker releases the U-shaped rod, the compression spring quickly extends and resets, allowing the two sets of inserts to connect with the insert holes. This achieves the effect of fixing and limiting the circular plate, thus quickly fixing and limiting the drive rod. This effectively prevents the screw from rotating and shifting due to external forces colliding with the drive rod, making the adjusted wheel more stable during use and providing convenience for the worker.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a ring main unit that is easy to transport, including a cabinet body 1, a base 101 at the bottom of the cabinet body 1, and baffles 102 symmetrically arranged at the top of the base 101, and a rain shield 103 installed between the tops of the baffles 102; a moving mechanism 2 is symmetrically arranged inside both ends of the base 101, and a limit component 3 is arranged inside the moving mechanism 2.

[0026] The moving mechanism 2 includes a support box 201, which is symmetrically installed inside both ends of the base 101. A fixed box 202 is installed at the top of the support box 201, and a screw 203 is rotatably connected between the fixed box 202 and the support box 201. A moving plate 204 is threadedly connected to the outer side of the screw 203, and a wheel 205 is installed at the bottom of the moving plate 204. A drive rod 206 is rotatably connected between the fixed box 202 and the baffle 102, and a first rotating... The first rotating tooth 207 and the second rotating tooth 208 are installed at the top of the screw 203. The first rotating tooth 207 and the second rotating tooth 208 are meshed together. The drive rod 206 is equipped with a sprocket 209 on the outside, and the sprocket 209 is meshed with a chain 210. This enables the cabinet 1 to be moved quickly. Compared with the existing technology, which requires the continuous adjustment of multiple sets of bolts, this method is more convenient and can greatly improve the flexibility of the cabinet 1 when used outdoors, bringing convenience to the staff.

[0027] The support box 201 has symmetrically opened limit grooves 211 on its inner side, and the two ends of the moving plate 204 are symmetrically installed with limit blocks 212. One end of the limit block 212 is slidably connected inside the limit groove 211. The movement of the moving plate 204 drives the movement of the two sets of limit blocks 212. At this time, the two sets of limit blocks 212 slide inside the limit groove 211, which makes the moving plate 204 more stable when it moves.

[0028] The bottom of the support box 201 is symmetrically equipped with fixing sleeves 213 on both sides, and the fixing sleeves 213 are inserted with insert rods 214. The insert rods 214 and the fixing sleeves 213 are symmetrically threaded with bolts 215. When the two sets of drive rods 206 rotate in opposite directions, the moving plate 204 moves upward and drives the wheel 205 to retract into the support box 201. At this time, the bottom of the support box 201 is in contact with the ground, and the bottom of the insert rod 214 is inserted into the ground, thereby achieving the effect of quick outdoor installation of the cabinet 1. The insertion of the insert rod 214 into the ground makes the cabinet 1 more stable during installation, greatly improves the efficiency of the device, and brings convenience to the staff. One end of the drive rod 206 is equipped with a handle 216. The design of the handle 216 makes it easy for the staff to operate the drive rod 206.

[0029] The limiting component 3 includes a fixed frame 301 symmetrically installed on one side of the bottom end of the baffle 102. A U-shaped rod 302 is slidably connected inside the top end of the fixed frame 301, and a connecting plate 303 is installed between the bottom ends of the U-shaped rod 302. A fixed tube 304 is installed inside the top end of the fixed frame 301, and a sliding rod 305 is slidably connected inside the fixed tube 304. The bottom end of the sliding rod 305 is fixedly connected to the connecting plate 303, and a compression spring 306 is sleeved on the outside of the sliding rod 305. Sliding sleeves 307 are symmetrically installed on both sides of the fixed tube 304, and the two ends of the U-shaped rod 302 pass through the sliding sleeves. The sleeve 307 is slidably connected to the sliding sleeve 307, and a circular plate 308 is installed on the outer side of one end of the drive rod 206. The outer side of the circular plate 308 is provided with insertion holes 309, and the bottom end of the connecting plate 303 is symmetrically provided with insertion blocks 310. The insertion blocks 310 are inserted into the insertion holes 309, thereby achieving the effect of quickly fixing and limiting the drive rod 206. This effectively avoids the phenomenon of the screw 203 rotating and deviating due to external force factors colliding with the drive rod 206, thus making the adjusted wheel 205 more stable when in use and bringing convenience to the staff.

[0030] Working principle: Before using this easily transportable ring main unit, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, by rotating two sets of drive rods 206, the operator drives the first rotating gear 207 to rotate. The rotation of the first rotating gear 207 drives the second rotating gear 208 to rotate. The rotation of the second rotating gear 208 drives the screw 203 to rotate. The rotation of the screw 203 drives the moving plate 204 to move up and down inside the support box 201. The downward movement of the moving plate 204 drives the wheel 205 to move. At this time, the rotation of the drive rods 206 drives the rotation of two sets of sprockets 209. Through the cooperation between the sprockets 209 and the chain 210, the four drive rods 206 rotate synchronously in the same direction. At this time, the four wheels 205 move down at the same time, lifting the base 101. Then, the operator pushes the cabinet 1 to move it, thus achieving the effect of quickly adjusting and moving the cabinet 1. This is more convenient than the existing technology that requires constantly adjusting multiple sets of bolts. This greatly improves the flexibility of the cabinet 1 when used outdoors, bringing convenience to the staff. When the two sets of drive rods 206 rotate in opposite directions, the moving plate 204 moves upward, driving the wheel 205 to retract into the support box 201. At this time, the bottom end of the support box 201 is in contact with the ground, and the bottom end of the insertion rod 214 is inserted into the ground, thus achieving the effect of quick outdoor installation of the cabinet 1. The insertion of the insertion rod 214 into the ground makes the cabinet 1 more stable during installation, greatly improving the efficiency of the device and bringing convenience to the staff. The movement of the moving plate 204 drives the movement of the two sets of limit blocks 212. At this time, the two sets of limit blocks 212 slide inside the limit groove 211, thus making the movement of the moving plate 204 more stable. The design of the handle 216 makes it easy for the staff to operate the drive rod 206.

[0031] When the worker pulls the U-shaped rod 302, it slides inside the top of the fixed frame 301. The movement of the U-shaped rod 302 causes the connecting plate 303 to move, and the movement of the connecting plate 303 causes the sliding rod 305 to slide inside the fixed tube 304. At this time, the compression spring 306 contracts, and the two ends of the U-shaped rod 302 slide inside the sliding sleeve 307. When the worker releases the U-shaped rod 302, the compression spring 306 quickly extends and resets, so that the two sets of insert blocks 310 are inserted into the insert holes 309, thereby achieving the effect of fixing and limiting the circular plate 308. This achieves the effect of quickly fixing and limiting the drive rod 206, effectively preventing the screw 203 from rotating and deviating due to external force collisions with the drive rod 206. This makes the adjusted wheel 205 more stable during use and brings convenience to the worker.

[0032] The cabinet 1 and the rain shield 103 are examples of existing technologies. The announcement number CN220874081U discloses a power ring network cabinet that is easy to install. The device used in the cabinet is not described in detail here.
