Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to a waterproof milling machine electrical cabinet. Background Technology

[0002] Road milling machines, as core equipment for highway and urban road maintenance, are widely used in excavation and repair of asphalt concrete surfaces, removal of road defects, and roughening of cement pavements. These machines are typically equipped with open folding or lifting canopies, protected by front and rear viewing windows. Electrical cabinets, as critical control units, are often located between the front and rear viewing windows, and due to passageway width limitations, they often employ a double-door design for easy maintenance. However, existing electrical cabinets face significant challenges in outdoor construction: during rainy weather, rainwater easily seeps from the bottom of the front viewing window into the top of the cabinet and then penetrates the interior through door gaps (especially the gap between double doors), causing short circuits, corrosion, or failure of electrical components, leading to equipment downtime and impacting construction efficiency and reliability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a waterproof milling machine electrical cabinet, including an electrical cabinet body, a left door and a right door;

[0004] The front end of the electrical cabinet body is provided with a door frame baffle, a water guide groove and two mounting plates;

[0005] The door frame baffle is a flat plate with continuous sides and is installed on the door frame of the electrical cabinet body; and the door frame baffle extends outwards along the door frame, with an upper drain outlet and a lower drain outlet respectively located at the middle of its upper and lower sides.

[0006] The water guide channel is located around the door frame baffle and is recessed inward on the outer surface of the door frame of the electrical cabinet body;

[0007] The two mounting plates are respectively welded to the back of the middle of the water guide channel. A U-shaped intermediate baffle is bolted between the two mounting plates. The upper and lower ports of the U-shaped groove of the U-shaped intermediate baffle correspond to the positions of the upper and lower drain outlets, respectively.

[0008] Both the left and right doors are rotatably mounted on the main door frame of the electrical cabinet via hinge bolts.

[0009] Preferably, the upper part of the electrical cabinet body is provided with a sloping platform, which is a structure with the front of the electrical cabinet facing inward and upward, forming an acute angle with the vertical surface.

[0010] Preferably, the inner side of the left door is provided with a first sealing strip, and the inner side of the right door is provided with a second sealing strip.

[0011] Preferably, the sides of the first sealing strip and the second sealing strip are pressed against the two sides of the U-shaped intermediate baffle, respectively.

[0012] Preferably, the left door is provided with a U-shaped bending baffle on the side near the right door, and the right door is provided with a limiting baffle on the side near the left door. The limiting baffle is pressed into the U-shaped opening of the U-shaped bending baffle to lock the left door when the right door is closed.

[0013] Preferably, the right door is equipped with cylindrical locks at both the top and bottom to lock the right door to the inside of the door frame of the electrical cabinet body.

[0014] This utility model provides a significantly optimized solution to address the shortcomings of existing milling machine electrical cabinets, with its core advantage lying in its waterproof reliability. In terms of waterproof design, this application utilizes a multi-stage drainage system integrating a sloping platform, a water guide channel, and a U-shaped drain outlet to effectively guide rainwater away from sensitive areas: the sloping structure of the platform alters the water flow direction, reducing direct impact; the water guide channel collects seepage and quickly discharges it through the upper and lower drain outlets in conjunction with the intermediate baffle, completely preventing water accumulation. Simultaneously, the compression and cooperation of the double-door sealing strips with the door frame baffle and the intermediate baffle forms a dynamic sealing barrier, particularly strengthening the sealing at door seams and preventing water penetration.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Reference Appendix Figure 1 -Appendix Figure 7 The main body 1 of the electrical cabinet serves as the core supporting structure, with a door frame baffle 101, a water guide channel 102, and a mounting plate 103 integrated at its front end. The door frame baffle 101 features a continuous flat design on all four sides, installed on the door frame and extending outwards. Its plane is parallel to the closed door, ensuring a smooth sealing surface. Upper drain outlets 104 and lower drain outlets 105 are located at the middle of the upper and lower edges of the door frame baffle 101, respectively. These drain outlets have a U-shaped structure, effectively guiding water flow and preventing water accumulation. The water guide channel 102 is embedded around the door frame, forming a U-shaped recessed structure. Its function is to collect any rainwater that may seep in and guide it to the drain outlets. The mounting plate 103 is welded to the back of the middle of the water guide channel 102 and connected to the U-shaped intermediate baffle 6 by bolts. This modular design facilitates disassembly and replacement. The groove of the U-shaped intermediate baffle 6 is aligned with the upper and lower drain outlets, forming a continuous drainage path to ensure smooth water discharge.

[0028] In one embodiment of this application, the upper part of the electrical cabinet body 1 is provided with a sloping platform 106. This structure extends inward and upward from the front of the electrical cabinet, forming an acute angle (e.g., 75-85°) with the vertical surface. This sloping design can change the direction of rainwater flow, allowing most of the rainwater to slide down along the sloping surface, reducing the probability of direct impact on the door seams. The sloping platform 106 is seamlessly connected to the door frame baffle 101, further enhancing the overall waterproof performance. In rainy outdoor environments, this structure can effectively reduce the risk of rainwater infiltration.

[0029] A first sealing strip 301 is affixed to the inside of the left door 3, and a second sealing strip 501 is affixed to the inside of the right door 5. These sealing strips are made of weather-resistant rubber material with high elasticity and compression deformation capacity. When the left door 3 or the right door 5 is closed, the first sealing strip 301 and the second sealing strip 501 are compressed and deformed, tightly adhering to the sides of the door frame baffle 101 and the U-shaped intermediate baffle 6, forming a multiple sealing barrier. The sides of the first sealing strip 301 and the second sealing strip 501 press against the two sides of the U-shaped intermediate baffle 6, respectively. This arrangement ensures the continuity of the seal at the door seam, maintaining the sealing effect even in high vibration environments.

[0030] In one embodiment of this application, a U-shaped bending baffle 302 is provided on the side of the left door 3 near the right door 5, and a limiting baffle 502 is provided on the side of the right door 5 near the left door 3. The limiting baffle 502 is designed with an L-shaped structure, which is pressed into the U-shaped opening of the U-shaped bending baffle 302 when the right door 5 is closed, forming a mechanical interlock. This mechanism can prevent the left door 3 from being accidentally opened under external force, while ensuring that the two doors are aligned. The cooperation between the bending baffle 302 and the limiting baffle 502 improves the stability of the doors.

[0031] A cylindrical lock 4 is installed at both the top and bottom of the right door 5 to lock the right door 5 to the inside of the door frame of the electrical cabinet body 1. The bolt of the cylindrical lock 4 has a telescopic function, which can adaptively adjust the compression force during the locking process to ensure that the first sealing strip 301 and the second sealing strip 501 are evenly compressed. This design not only provides reliable locking force but also avoids damage to the sealing strips due to overpressure. The mounting holes of the cylindrical lock 4 are pre-set on the right door 5 for easy assembly and maintenance.

[0032] The working principle of this electrical cabinet is based on fluid mechanics and mechanical sealing principles, ensuring waterproof performance in harsh environments. The specific process is as follows:

[0033] Door closing and sealing mechanism: During operation, the left door 3 is closed first, allowing the first sealing strip 301 to initially adhere to the door frame. Then, the right door 5 is closed, and the limiting baffle 502 is pressed into the U-shaped opening of the U-shaped bending baffle 302, forming a mechanical lock. Simultaneously, the cylindrical lock 4 is activated, the bolt extends and retracts, compressing the second sealing strip 501, causing it to elastically deform and press against the door frame baffle 101 and the U-shaped intermediate baffle 6. This dynamic sealing design ensures uniform pressure distribution at the door seams, effectively preventing moisture penetration.

[0034] Waterproof drainage system: When rainwater flows in from the top of the electrical cabinet, the sloping structure of the recessed platform 106 changes the direction of water flow through gravity, causing most of the rainwater to flow away from the door area along the slope. A small amount of infiltrated rainwater is collected by the water guide channel 102 and guided through the U-shaped structure to the upper drain outlet 104 and the lower drain outlet 105. When the water flows through the channel of the U-shaped intermediate baffle 6, it is naturally discharged by gravity, avoiding water accumulation. The U-shaped design of the water guide channel 102 increases the length of the water flow path and improves drainage efficiency.

[0035] Maintainable design: The bolted assembly of hinge 2 allows for quick replacement. If the hinge is damaged, repair can be performed simply by removing the bolts without welding, reducing downtime. The entire system is based on a modular design, and components such as the intermediate baffle 6 and the sealing strip can be replaced independently, improving service life and economy.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
