Description

Technical Field

[0001] This utility model belongs to the technical field of metering boxes, specifically relating to a waterproof retaining ring structure for a metering box cable outlet cover. Background Technology

[0002] A metering box is a box used to install electrical energy metering devices (such as electricity meters, instrument transformers, etc.). It plays a vital role in the power system. Common materials include metals (such as cold-rolled steel plates, stainless steel, etc.) and non-metals (such as engineering plastics, fiberglass, etc.). Metering boxes are usually equipped with a door to facilitate the operation and maintenance of the internal equipment. The outgoing line protection box is an important component in the metering box used to protect and organize the outgoing lines.

[0003] Outgoing cable guards are usually installed on the door surface of metering boxes to accommodate and protect cables or wires leading out of the metering box. The front cover of the outgoing cable guard is hinged, and there will be gaps at the hinge. In humid environments such as rainy days, rainwater can easily seep into the inside of the guard through these gaps, causing the internal circuits to become damp. To address this, a waterproof retaining ring structure for the outgoing cable guard of the metering box is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof retaining ring structure for the metering box outlet cover to solve the technical problem that rainwater can easily seep into the cover through these gaps, causing the internal wiring to become damp.

[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof retaining ring structure for the outlet guard box of a metering box, including a metering box door, an outlet guard box fixedly installed through the bottom of the surface of the metering box door, and a cover plate hinged to the top of the front side of the inner cavity of the outlet guard box.

[0006] A baffle plate is fixedly connected to the inner cavity of the cable outlet box. A top plate is fixedly connected to the top of the baffle plate. Two guide plates are fixedly connected to the top of the top plate. A water guide groove is opened on the top surface of the guide plate. A flow-blocking plate is fixedly connected to both sides of the baffle plate. A bottom plate is fixedly connected to the bottom of the inner cavity of the cable outlet box. A drainage groove is opened on both sides of the top surface of the bottom plate.

[0007] Furthermore, the baffle plate is U-shaped, the length of the baffle plate is the same as the length of the top plate, and the two sides of the baffle plate are fixedly connected to the two sides of the top plate.

[0008] Furthermore, the two guide vanes are symmetrically distributed, and the two guide vanes are high in the middle and low on both sides.

[0009] Furthermore, a sealing strip is provided on the side of the guide plate that is in contact with the outlet cable cover.

[0010] Furthermore, the front side of the top plate is curved upwards.

[0011] Furthermore, the top surface of the base plate is inclined at the back and low at the front, the bottom of the drainage trough cavity is inclined at the same angle, and the two drainage troughs are located directly below the two sides of the baffle plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. When rainwater leaks into the outlet box from the hinge, it first reaches the top surface of the top plate. Guided by the guide plate and water channel, the rainwater can quickly flow to both sides of the top plate and fall down, preventing it from accumulating inside the outlet box and forming puddles. This effectively reduces the increase in internal humidity caused by water accumulation, avoids the line being in a humid environment for a long time, and reduces the probability of line insulation performance degradation, short circuits and other faults.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, a waterproof retaining ring structure for a metering box outlet cover includes a metering box door 1, an outlet cover 2 fixedly installed through the bottom of the metering box door 1, a cover plate 3 hinged to the top of the front side of the outlet cover 2, a baffle plate 4 fixedly connected to the inner cavity of the outlet cover 2, a top plate 5 fixedly connected to the top of the baffle plate 4, two guide plates 6 fixedly connected to the top of the top plate 5, a water guide groove 7 opened on the top surface of the guide plates 6, and flow-blocking plates 8 fixedly connected to both sides of the baffle plate 4. The flow-blocking plates 8 fixedly connected to both sides of the baffle plate 4 can block rainwater and prevent rainwater from flowing from both sides of the baffle plate 4 to the front side of the baffle plate 4, ensuring that rainwater can flow along the vertical path on both sides of the baffle plate 4, thereby enhancing the water-blocking effect of the baffle plate 4. A bottom plate 9 fixedly connected to the bottom of the inner cavity of the outlet cover 2, and drainage grooves 10 opened on both sides of the top surface of the bottom plate 9.

[0026] The water baffle 4 is U-shaped, and its U-shaped structure can better guide the flow of rainwater, allowing it to flow smoothly to both sides. This serves to block and guide the rainwater, preventing it from penetrating deeper into the cable outlet box 2 and confining it to a relatively controllable area, thus avoiding damage to more critical components inside the box. The length of the water baffle 4 is the same as the length of the top plate 5, and both sides of the water baffle 4 are fixedly connected to the sides of the top plate 5. When rainwater leaks into the cable outlet box 2 from the hinge joint... When rainwater enters the box 2, it first reaches the top surface of the top plate 5. The top plate 5 serves to collect rainwater, providing a foundation for the subsequent diversion process. The top plate 5 is fixedly connected to the guide plate 6, which works with the guide plate 6 to guide the rainwater to both sides of the baffle plate 4. The two guide plates 6 are symmetrically distributed, with the middle being higher than the sides, which can quickly guide the rainwater on the top plate 5 to both sides. The water-guiding grooves 7 opened on the top surface of the guide plate 6 can further enhance the diversion effect, making the rainwater flow in a specific direction and avoiding... Rainwater accumulates on the top plate 5, accelerating its drainage. A sealing strip is installed on the side of the guide plate 6 that fits against the cable outlet box 2, filling the gap between them and preventing rainwater from seeping into the box. This enhances the sealing performance of the entire waterproof structure. The front of the top plate 5 is angled upwards to prevent rainwater from accumulating on its front and flowing back into the cable outlet box 2, further improving the waterproofing effect. The top surface of the bottom plate 9... With a rear-high, front-low sloping design, the bottom of the inner cavity of the drainage channel 10 is also sloping. The two drainage channels 10 are located directly below the two sides of the baffle plate 4, which can accurately collect rainwater flowing down from both sides of the baffle plate 4 and guide it out of the cable outlet box 2. The sloping bottom design can speed up the drainage speed of rainwater and prevent rainwater from accumulating in the drainage channel 10. The sloping design of the drainage channel 10 can also prevent external rainwater from flowing back into the cable outlet box 2, further improving the waterproof performance of the cable outlet box 2.

[0027] In summary, when rainwater leaks into the interior of the cable tray 2 from the hinge joint between the cover plate 3 and the cable tray 2, it first falls onto the top surface of the top plate 5. The top plate 5, as the first "platform" to receive rainwater, provides the foundation for the subsequent diversion process. At this time, the guide plate 6 above the top plate 5 begins to function, causing the rainwater falling on the top plate 5 to flow naturally to the lower sides. At the same time, the water channel 7 opened on the top surface of the guide plate 6 further enhances the diversion effect. Under the guidance of the guide plate 6, the rainwater flows to the sides of the top plate 5 and then falls. At this time, it flows past the sides of the baffle plate 4. Under the obstruction of the baffle plate 8, the rainwater flows vertically downward along the sides of the baffle plate 4. The drainage channel 10 can accurately collect the rainwater flowing down from the sides of the baffle plate 4. The inclined bottom design of the drainage channel 10 can accelerate the discharge speed of the rainwater, so that the rainwater can be quickly discharged outside the cable tray 2, avoiding the accumulation of rainwater inside the tray.
