Description

Technical Field

[0001] This invention relates to the field of metering cabinet technology, and in particular to a metering cabinet with leakage protection indication function. Background Technology

[0002] A metering cabinet is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. Currently, power companies install all the electricity metering boxes in one building to monitor electricity and facilitate management. However, this centralized arrangement can easily lead to leakage, and pedestrians often cannot detect the leakage, resulting in electric shock accidents.

[0003] Patent publication number CN212459805U discloses a metering cabinet with leakage protection function that is easy to install. The cabinet includes a cabinet body, rubber rings, and an insulating layer. Fixing blocks are fixed to the four outer corners of the cabinet body, and fixing bolts are provided on the inner side of the fixing blocks. A hinge is provided on one side of the upper interior of the cabinet body, and a door is connected to the other side of the hinge. A rubber ring is provided on the inner side of the door, and glass is fixed to the upper end of the door. However, this patent achieves leakage protection by adding an insulating layer inside the fixed frame, and it does not provide a barrier around the cabinet. This means that when the metering cabinet leaks electricity, pedestrians cannot detect it, making it easy for them to approach the metering cabinet and cause electric shock accidents.

[0004] In summary, it is necessary to develop a metering cabinet with leakage protection and a leakage current warning function that can automatically surround the metering cabinet. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies that rely solely on adding insulation layers to achieve leakage protection, which cannot effectively enclose the area around the cabinet and allows pedestrians to easily approach the leaking metering cabinet, resulting in low safety, this invention provides a metering cabinet with leakage protection and alert functions that can automatically enclose the area around the metering cabinet.

[0006] To achieve the above objectives, the present invention provides the following solution: a metering cabinet with leakage current protection indication function, comprising:

[0007] The cabinet and the grid panels: grid panels are installed on the upper left and right sides of the cabinet to facilitate heat dissipation.

[0008] A rotating door is located on the front left side of the cabinet.

[0009] Protective mechanisms are provided on the cabinet and rotating doors to surround the cabinet.

[0010] The cabinet and the grid plate are equipped with a closing mechanism for closing the grid plate.

[0011] Furthermore, protective institutions include:

[0012] There are two electrical wires connected to the upper left side of the inner wall of the cabinet, and a closed frame is installed on the upper left side of the inner wall of the cabinet.

[0013] The light bulb is installed inside the closed frame on the inner wall of the cabinet, and two wires pass through the closed frame on the inner wall of the cabinet and are connected to the light bulb.

[0014] Photoelectric sensor: A photoelectric sensor is installed inside the closed frame on the inner wall of the cabinet.

[0015] An electric push rod is connected to the upper part of the rear wall inside the cabinet. The electric push rod is electrically connected to the photoelectric sensor.

[0016] The sliding frame is slidably connected to the upper rear side of the cabinet. The top of the telescopic rod of the electric push rod is connected to the upper part of the sliding frame. The sliding frame is n-shaped.

[0017] The first connecting rod is rotatably connected to both the left and right sides of the lower part of the sliding frame;

[0018] Fixed frames are attached to the lower left, right, and rear sides of the cabinet, and a fixed frame is attached to the lower front side of the rotating door.

[0019] The first rotating rod is rotatably connected to both the left and right sides of the fixed frame, and the lower part of the first connecting rod is rotatably connected to the middle part of the adjacent first rotating rod.

[0020] The connecting frame has a rotatable connection between the first rotating rods on the front, back, left and right sides of the cabinet, which is used to enclose the area around the cabinet.

[0021] The upper left side of the connecting frame on both the front and rear sides is rotatably connected with a buckle for locking the connecting frame. The buckle on the front side passes through and locks the rotating door, and the buckle on the rear side passes through and locks the cabinet.

[0022] The first torsion spring is fitted on the lower part of the buckle, and the two ends of the first torsion spring are connected to the buckle and the connecting frame, respectively.

[0023] Furthermore, the closed-loop mechanism includes:

[0024] The second connecting rod is rotatably connected to both the left and right sides of the lower part of the sliding frame;

[0025] The upper part of the second rotating rod and the second connecting rod are rotatably connected to the second rotating rod, and the second rotating rod passes through the cabinet.

[0026] The cam and the inner side of the second rotating rod are both connected to cams;

[0027] The cabinet has sliding closing plates on both the left and right sides of the upper part for closing the grid plate. When the cam rotates, it no longer holds the closing plate, and the closing plate moves down to close the grid plate.

[0028] Fixed levers are connected to both the front and rear sides of the middle of the left-side closing plate for pressing the latch to unlock.

[0029] Furthermore, it also includes a connecting mechanism for resetting the connecting frames on both the front and rear sides, the connecting mechanism including:

[0030] Fixed blocks are connected to both the upper left side of the connecting frame and the fixed blocks.

[0031] Rotating rings are rotatably connected to the upper right side of the connecting frame;

[0032] Connecting bars are attached to both the connecting bars and the fixing blocks, and the connecting bars are wrapped around the adjacent rotating rings;

[0033] The mainspring and the upper part of the rotating coil are connected to the adjacent connecting frame. The mainspring drives the rotating coil to rotate and wind up the connecting bar. The connecting bar drives the connecting frames on the front and rear sides to rotate upward and reset.

[0034] Furthermore, it also includes a lifting mechanism for alerting pedestrians, the lifting mechanism comprising:

[0035] The third link is connected to the rear side of the second rotating rod;

[0036] The third connecting rod is rotatably connected to the rear side of the third connecting rod;

[0037] A rotating frame is rotatably connected to the top front of the cabinet, and the upper part of the third connecting rod is rotatably connected to the rotating frame.

[0038] The first warning board is embedded inside the rotating frame and is used to remind pedestrians.

[0039] Furthermore, the first signboard has a more vibrant color.

[0040] Furthermore, it also includes warning agencies, which include:

[0041] The skateboard has a sliding connection inside the connecting frame on both the left and right sides;

[0042] The second warning board is connected to the outside of the skateboard to warn pedestrians. The second warning board is brightly colored and has through holes in the middle of the connecting frame on both the left and right sides.

[0043] The sliding rods are connected to both the front and rear sides of the bottom of the skateboard, and the sliding rods slide inside the adjacent connecting frame.

[0044] Furthermore, it also includes a locking mechanism for locking the sliding frame, the locking mechanism comprising:

[0045] A mounting bracket is attached to the upper rear part of the inner wall of the cabinet.

[0046] A limit lever is rotatably connected to the fixed frame for locking the sliding frame;

[0047] The second torsion spring is fitted under the lower part of the limiting rod. The two ends of the second torsion spring are connected to the limiting rod and the right side of the fixing frame, respectively. A slot is opened on the front side of the middle part of the sliding frame.

[0048] This invention has at least one of the following advantages: By moving the sliding frame downwards, the first connecting rod, the first rotating rod, and the connecting frame rotate downwards to contact the ground. This effectively encloses the area around the cabinet, preventing pedestrians from unintentionally approaching the cabinet and causing electric shock in case of leakage. Furthermore, as the connecting frame rotates downwards, the closing plate moves downwards to close the mesh plate, preventing rainwater from entering the cabinet and conducting electricity, thus ensuring high safety. When the connecting frames on the left and right sides rotate upwards to reset, the spring's reset action drives the rotating ring to wind up the connecting strip, automatically causing the connecting frames on the front and rear sides to rotate upwards and reset. This eliminates the need for manual control of the front and rear connecting frames, reducing operational hassle. The system is designed to be user-friendly. The first warning panel, illuminated in bright red, rotates forward to a vertical position via the second rotating rod, alerting pedestrians and preventing them from approaching the cabinet. The sliding rod, in contact with the ground, moves the sliding plate and the second warning panel upward relative to the connecting frame, positioning the second warning panel at the through-hole on the connecting frame. This enhances the warning effect for pedestrians on both sides. The second torsion spring rotates the limit lever, engaging it in the slot on the sliding frame. This locks the limit lever in place, preventing pedestrians from maliciously lifting the connecting frame upwards and resetting it. It also prevents a fire inside the cabinet from causing the electric push rod to malfunction and move the sliding frame upwards, thus improving the stability of the connecting frame.

Detailed Implementation

[0072] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0073] Example 1

[0074] A metering cabinet with leakage protection indication function, such as Figures 1-12As shown, the cabinet includes a cabinet body 1, a mesh panel 2, a rotating door 3, a protective mechanism 4, and a closing mechanism 5. Mesh panels 2 are installed on both the upper left and right sides of the cabinet body 1 to facilitate heat dissipation. A rotating door 3 is hinged to the front left side of the cabinet body 1. Protective mechanisms 4 are provided on the cabinet body 1 and the rotating door 3 to enclose the cabinet body 1. Closing mechanisms 5 are provided on the cabinet body 1 and the mesh panel 2 to close the mesh panel 2. The protective mechanism 4 includes wires 41, a light bulb 42, a photoelectric sensor 43, an electric push rod 44, a sliding frame 45, a first connecting rod 46, a fixing frame 47, a first rotating rod 48, a connecting frame 49, a buckle 410, and a first torsion spring 411. Two wires 41 are connected to the upper left side of the inner wall of the cabinet body 1. A closed frame is installed inside the cabinet 1. A light bulb 42 is installed inside the closed frame on the inner wall of the cabinet 1. Two wires 41 pass through the closed frame on the inner wall of the cabinet 1 and are connected to the light bulb 42. A photoelectric sensor 43 is installed inside the closed frame on the inner wall of the cabinet 1. An electric push rod 44 is fixed to the upper part of the inner rear wall of the cabinet 1 by bolts. The electric push rod 44 is electrically connected to the photoelectric sensor 43. A sliding frame 45 is slidably connected to the upper rear side of the inner part of the cabinet 1. The top of the telescopic rod of the electric push rod 44 is fixed to the upper part of the sliding frame 45. The sliding frame 45 is n-shaped. The lower left and right sides of the sliding frame 45 are rotatably connected to the first connecting rod 46 by pins. Fixed frames 47 are fixed to the lower left, right and rear sides of the lower part of the cabinet 1. A fixed frame 47 is fixed to the lower front side of the rotating door 3. The four fixed frames 47 are connected to the left and right sides by... Two first rotating rods 48 are rotatably connected by pins. The lower parts of two first connecting rods 46 are rotatably connected to the middle of the adjacent first rotating rods 48. A connecting frame 49 is rotatably connected between the four first rotating rods 48 on the front side. The connecting frame 49 is used to surround the cabinet 1. A connecting frame 49 is rotatably connected between the four first rotating rods 48 on the rear side, the four first rotating rods 48 on the left side, and the four first rotating rods 48 on the right side. The upper left part of the connecting frame 49 on both the front and rear sides is rotatably connected to a buckle 410 by a pin. The buckle 410 is used to lock the connecting frame 49. The buckle 410 on the front side passes through and locks the rotating door 3, and the buckle 410 on the rear side passes through and locks the cabinet 1. Both buckles 410 have a first torsion spring 411 fitted at their lower parts. The two ends of the first torsion spring 411 are connected to the buckle 410 and the connecting frame 49, respectively. The closing mechanism 5 includes a second connecting rod 51, a second rotating rod 52, a cam 53, a closing plate 54, and a fixed lever 55. The lower left and right sides of the sliding frame 45 are rotatably connected to the second connecting rod 51 by pins. The upper parts of the two second connecting rods 51 are rotatably connected to the second rotating rod 52 by pins. The upper parts of the two second rotating rods 52 pass through the cabinet 1. The inner sides of the two second rotating rods 52 are fixedly connected to the cam 53. The upper left and right sides of the cabinet 1 are slidably connected to the closing plate 54, which is used to close the grid plate 2. The middle front and rear sides of the left closing plate 54 are fixedly connected to the fixed lever 55.The fixed lever 55 is used to press the latch 410 to unlock.

[0075] In use, cam 53 initially presses against closing plate 54, making closing plate 54 and grid plate 2 initially connected, facilitating ventilation inside cabinet 1. When the equipment inside cabinet 1 leaks electricity, wire 41 will conduct the leaked electricity to bulb 42, causing bulb 42 to light up. When photoelectric sensor 43 detects that the brightness has reached the preset value, it controls electric push rod 44 to start for five seconds and then stop. The telescopic rod of electric push rod 44 retracts, driving sliding frame 45 to move downward, thereby driving first connecting rod 46 to move downward, and simultaneously driving second connecting rod 51 to move downward, causing first connecting rod 46 to rotate outward, which in turn drives corresponding first rotating rod 48 to rotate outward, supporting connecting frame 49 outward. When the second connecting rod 51 pulls the second rotating rod 52, it drives the cam 53 to rotate, causing the cam 53 to no longer press against the closing plate 54. Under its own weight, the closing plate 54 moves downward to close the grid plate 2. This prevents rainwater from entering the cabinet 1 and avoids the rainwater conducting electricity, which could cause an electric shock. When the closing plate 54 on the left moves downward, it drives the fixed lever 55 to move downward, causing the fixed lever 55 to press the buckle 410 downward and rotate it to separate it from the rotating door 3 and the cabinet 1. The torsion spring deforms. At the same time, the fixed lever 55 pushes the buckle 410 to move outward, causing the corresponding connecting frame 49 and the first rotating rod 48 to rotate outward and unfold, thereby causing the four connecting frames 49 to move downward. Rotate until it contacts the ground, thus surrounding the cabinet 1. This prevents pedestrians from accidentally approaching the cabinet 1 and causing an electric shock if the equipment inside leaks electricity. It also serves as a warning to pedestrians not to approach the cabinet 1. When staff are repairing the equipment inside the cabinet 1, the power to the equipment is cut off, and the light bulb 42 stops lighting up. Then, the staff activates the electric push rod 44, controlling its extension rod to return to its original position. This causes the sliding frame 45 to move upwards and return to its original position, thereby causing the first connecting rod 46 and the second connecting rod 51 to move upwards and return to their original positions. The first connecting rod 46 then causes the corresponding first rotating rod 48 and connecting frame 49 to rotate upwards and return to their original positions. The second connecting rod 51 pushes the second rotating shaft to reverse and reset. The second rotating shaft drives the cam 53 to reverse, so that the cam 53 lifts the closing plate 54, so that the closing plate 54 reconnects with the grid plate 2. The closing plate 54 then drives the fixed lever 55 to move upward and reset, separating from the buckle 410. The first torsion spring 411 resets, driving the buckle 410 to reverse and reset. Then, the staff manually lifts the connecting brackets 49 on the front and rear sides, driving the first rotating rods 48 on the front and rear sides to reverse and reset, driving the buckle 410 to re-engage in the rotating door 3 and cabinet 1 to lock the connecting brackets 49. Then, the electric push rod 44 is turned off. This makes it easier for the staff to maintain the equipment inside the cabinet 1.

[0076] Example 2

[0077] Based on Example 1, such as Figure 1 , Figure 2 , Figure 13 , Figure 14 and Figure 15 As shown, it also includes a connecting mechanism 6, which is used to drive the connecting frames 49 on the front and rear sides to reset. The connecting mechanism 6 includes a fixing block 61, a rotating ring 62, a connecting bar 63, and a spring 64. The upper left side of each of the four connecting frames 49 is fixedly connected to a fixing block 61, and the upper right side of each of the four connecting frames 49 is rotatably connected to a rotating ring 62. The four fixing blocks 61 are connected to a connecting bar 63, and the four connecting bars 63 are wound around the adjacent rotating rings 62. The upper part of each of the four rotating rings 62 is connected to the adjacent connecting frame 49 by a spring 64. When the first rotating rod 48 pushes the connecting frame 49 to rotate outward, it drives the fixed block 61, rotating ring 62, connecting strip 63 and spring 64 to move outward. Under the action of the pulling force, the rotating ring 62 rotates to release the connecting strip 63, and the spring 64 deforms accordingly. When the first rotating rod 48 drives the connecting frames 49 on the left and right sides to rotate upward and reset, the spring 64 resets, and drives the rotating ring 62 to reverse and wind up the connecting strip 63. This can drive the connecting frames 49 on the front and rear sides to rotate upward and reset. In this way, there is no need to manually control the reset of the connecting frames 49 on the front and rear sides, reducing the trouble of operation.

[0078] like Figure 1 , Figure 2 , Figure 3 , Figure 16 and Figure 17 As shown, it also includes a lifting mechanism 7, which is used to remind pedestrians. The lifting mechanism 7 includes a third link 71, a third connecting rod 72, a rotating frame 73, and a first warning plate 74. The rear sides of the two second rotating rods 52 are fixedly connected to the third link 71, and the rear sides of the two third link 71 are rotatably connected to the third connecting rod 72 through pins. The rotating frame 73 is rotatably connected to the front top of the cabinet 1. The upper parts of the two third connecting rods 72 are rotatably connected to the rotating frame 73. The first warning plate 74 is embedded inside the rotating frame 73. The first warning plate 74 is used to remind pedestrians. The color of the first warning plate 74 is bright red. When the second rotating rod 52 rotates, it drives the third connecting rod 71 to rotate upward, which in turn drives the third connecting rod 72 to rotate upward. The third connecting rod 72 pushes the rotating frame 73 to rotate forward, which in turn drives the first indicator plate 74 to rotate forward and into a vertical position. The color of the first indicator plate 74 can be a bright and eye-catching color, so as to remind pedestrians on the front and back sides and prevent pedestrians from approaching the cabinet 1, so that pedestrians can go around it on their own. When the second rotating rod 52 reverses and resets, it drives the third connecting rod 71 to rotate downward and reset. The third connecting rod 71 drives the third connecting rod 72, the rotating frame 73 and the first indicator plate 74 to rotate downward and reset.

[0079] like Figure 1 , Figure 2 , Figure 3 , Figure 18 , Figure 19 and Figure 20 As shown, it also includes a warning mechanism 8, which includes a second warning board 82, a sliding plate 81, and a sliding rod 83. The sliding plate 81 is slidably connected inside the connecting frame 49 on both the left and right sides. The second warning board 82 is fixed to the outside of both sliding plates 81. The second warning board 82 is used to warn pedestrians. The second warning board 82 is bright red. The connecting frame 49 on both the left and right sides has a through hole in the middle. The sliding rod 83 is fixed to the front and rear sides of the bottom of both sliding plates 81. The four sliding rods 83 are all located inside the adjacent connecting frame 49 and slide. When the connecting frames 49 on both sides rotate to contact the ground, the sliding rod 83 contacts the ground first. The connecting frames 49 on both sides continue to move downward, causing the slide plate 81 and the second warning plate 82 to move upward relative to the connecting frames 49. This causes the second warning plate 82 to move to the through hole on the connecting frame 49. Since the second warning plate 82 is brightly colored, it can serve as a warning to pedestrians on both sides, thus achieving an all-round warning effect and enhancing the warning effect. When the connecting frames 49 on both sides rotate upward to reset, they drive the second warning plate 82, the slide plate 81, and the sliding rod 83 to move upward to reset, causing the second warning plate 82, the slide plate 81, and the sliding rod 83 to move downward to reset.

[0080] like Figure 3 , Figure 21 and Figure 22As shown, it also includes a locking mechanism 9, which is used to lock the sliding frame 45. The locking mechanism 9 includes a fixed frame 91, a limiting rod 92, and a second torsion spring 93. The fixed frame 91 is fixedly connected to the upper rear part of the inner wall of the cabinet 1. The limiting rod 92 is rotatably connected to the fixed frame 91. The limiting rod 92 is used to lock the sliding frame 45. The lower part of the limiting rod 92 is fitted with the second torsion spring 93. The two ends of the second torsion spring 93 are respectively connected to the limiting rod 92 and the right side of the fixed frame 91. A slot is opened on the front side of the middle part of the sliding frame 45. When the sliding frame 45 moves downwards and contacts the limiting lever 92, the limiting lever 92 is squeezed and rotated forward. The second torsion spring 93 deforms. When the slot on the sliding frame 45 moves downwards and approaches the limiting lever 92, the second torsion spring 93 resets, causing the limiting lever 92 to rotate backwards and reset into the slot on the sliding frame 45. In this way, the sliding frame 45 can be locked, preventing pedestrians from maliciously lifting the connecting frame 49 upwards and resetting it. It can also prevent a fire inside the cabinet 1 from causing the electric push rod 44 to malfunction and drive the sliding frame 45 upwards and reset. When the staff opens the rotating door 3, they manually push the limiting lever 92 forwards to separate it from the sliding frame 45, and then control the extension rod of the electric push rod 44 to extend and drive the sliding frame 45 upwards and reset it. Then, the limiting lever 92 is released, and the second torsion spring 93 drives the limiting lever 92 to reverse and reset.

[0081] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
