Description

Technical Field

[0001] This utility model relates to a waterproof instrument panel for a distribution box, belonging to the technical field of instrument panels for distribution boxes. Background Technology

[0002] The national infrastructure sector, including railways, highways, aviation, shipping, industry and mining, healthcare, and housing, has developed rapidly and has become an important pillar industry of the national economy. Outdoor temporary power distribution boxes (outdoor distribution boxes) are required at various construction sites according to their scale. These are 3C mandatory certified products with functions such as power distribution, overload protection, and power metering and monitoring, and are widely used throughout the country. To facilitate the viewing of data changes during use, instrument panels are usually installed on the door of the distribution boxes.

[0003] While current electrical distribution boxes are equipped with instrument panels that can effectively handle daily data display tasks, they reveal several shortcomings in practical applications. Regarding waterproofing, the instrument panel primarily relies on its fixed transparent cover to protect against external moisture. However, when subjected to prolonged direct erosion from rain, the cover, the instrument panel body, and surrounding connections cannot withstand this continuous impact and corrosion. This easily leads to tiny gaps or seal failure at the joints, allowing rainwater to seep in. This inevitably results in water entering the instrument panel, severely affecting its normal operation and ultimately demonstrating insufficient waterproofing.

[0004] Meanwhile, in everyday use, the transparent cover, due to its exposed position, easily attracts and accumulates a large amount of dust. Over time, dust gradually covers the surface of the cover, not only greatly interfering with the clarity of the data display, making it difficult for staff to read the data accurately and quickly, but also requiring staff to clean the cover regularly to ensure the accuracy and visibility of the dashboard data. This undoubtedly increases the workload and frequency of work for staff, disrupting the normal work rhythm and process to some extent, causing many inconveniences for staff operation, and ultimately making the dashboard less user-friendly.

[0009] The instrument panel body is fixed to one end of a fixed frame. The fixed frame has a rotating groove on each adjacent corner away from the transparent frame. The inner walls of the two rotating grooves are rotatably connected to rotating frames. One end of each rotating frame is fixed with a torsion spring, and the other side of each rotating frame is fixed with a closing plate.

[0010] The fixing frame has two sliding grooves on the side near the transparent frame, and each of the two closed plates has a through groove in the middle. The inner wall of the two through grooves is provided with a connecting structure, and two brush holders are provided on the connecting structure. The connecting structure can slide the two brush holders in the opposite direction along the height of the transparent frame to sweep and clean the dust on the surface of the transparent frame.

[0011] Preferably, the connection structure includes two drive frames, each with a slider fixed at one end and a brush holder fixed at the other end.

[0012] Preferably, the outer surface of each drive frame is slidably connected to the inner wall of each through slot, the cross section of each drive frame is T-shaped, and the two through slots pass through the middle of the two closed plates.

[0017] This utility model provides a waterproof instrument panel for a power distribution box, which has the following beneficial effects:

[0018] (1) The distribution box uses a waterproof instrument panel. Rainwater washes the sealing plate, so that the sealing plate, rotating frame, rotating groove and torsion spring work together to achieve the effect of force buffering. This avoids rainwater directly washing the transparent frame and causing leakage at the connection, thereby improving the waterproof performance of the instrument panel.

[0019] (2) The distribution box uses a waterproof instrument panel. When the staff manually presses the two closed plates, the closed plates, drive frame, through groove, slider, slide groove and brush frame work together to achieve automatic cleaning. Whenever the staff opens the closed plate to check the instrument panel data, the cleaning of the transparent frame will start automatically. The staff does not need to spend extra time and energy to prepare for the cleaning, which greatly reduces the staff's operating burden and improves the ease of use of the instrument panel.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] This utility model provides a waterproof instrument panel for a power distribution box.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The distribution box includes a main body 1, which is an electrical device used to distribute electrical energy, control circuit switching, and protect electrical equipment. It plays a crucial role in the power system and is widely used in various industrial, commercial, and civil buildings. A door 2 is located on one side of the main body 1, which closes the main body 1. An instrument panel 3 is detachably mounted on the center of the door 2 via bolts. The instrument panel 3 displays various parameters of the circuit within the distribution box; for example, a voltmeter displays the voltage value in real time, allowing the operator to... The operator can clearly understand whether the voltage level of the power supply is stable within the normal range, and the ammeter accurately indicates the current magnitude to help judge the current load of each branch or equipment so as to detect overload and other abnormalities in a timely manner; a transparent frame 4 is fixed to one end of the instrument panel body 3, which facilitates the user's observation; a fixing bracket 5 is fixed to one end of the instrument panel body 3, and a rotating groove 6 is opened on the adjacent corner of the fixing bracket 5 away from the transparent frame 4. A rotating frame 7 is rotatably connected to the inner wall of the two rotating grooves 6. A torsion spring 8 is fixed to one end of the two rotating frames 7, and a closing plate 9 is fixed to the other side of the two rotating frames 7.

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surfaces of the two closed plates 9 are rotatably connected to the inner walls of both sides of the fixed frame 5, the two closed plates 9 are fixed at opposite ends to the middle of the two rotating frames 7, the outer surfaces of the two rotating frames 7 are rotatably connected to the inner walls of the two rotating grooves 6, the cross sections of the two rotating frames 7 are both cross-shaped, one end of the two torsion springs 8 is fixed to one end of the two rotating frames 7, and the other end of the two torsion springs 8 is fixed to the inner walls of the two rotating grooves 6. The four corners of the distribution box body 1 away from the box door 2 are all fixed with mounting brackets 15, and each mounting bracket 15 has a reserved hole 16 in the middle.

[0031] In use, this invention utilizes rainwater to wash over the sealing plate 9, allowing it to smoothly rotate under the stable support of the rotating frame 7 and the rotating groove 6. As the sealing plate 9 rotates, the rigidly connected rotating frame 7 rotates synchronously. This rotation applies a tensile force to the torsion spring 8, which is installed at a specific position and tightly connected to the rotating frame 7. This causes the torsion spring 8 to undergo corresponding elastic deformation and accumulate elastic potential energy. The elastic force converted from this potential energy effectively resists and buffers the impact of rainwater washing, preventing rainwater from directly impacting the transparent frame 4. If rainwater directly washes over the transparent frame 4 for a prolonged period, the sealing performance at the connection points with surrounding components will gradually decrease due to continuous external impact and rainwater erosion, potentially leading to leakage. The buffer structure formed by the sealing plate 9 and the torsion spring 8 significantly reduces this risk. This achieves a stress buffering effect, preventing rainwater from directly washing over the transparent frame 4 and causing leakage at the joints, thereby improving the waterproof performance of the dashboard.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic cleaning function has been added based on Embodiment 1;

[0034] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the fixing frame 5 has two sliding grooves 13 on the side near the transparent frame 4, and the two closed plates 9 each have a through groove 10 in the middle. The inner wall of the two through grooves 10 is provided with a connecting structure, which includes two drive frames 11. One end of each drive frame 11 is fixed with a slider 12, and the other end of each slider 12 is fixed with a brush holder 14.

[0035] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surface of each drive frame 11 is slidably connected to the inner wall of each through groove 10, and the cross-section of each drive frame 11 is T-shaped. The two through grooves 10 pass through the middle of the two closed plates 9. One end of the two drive frames 11 is fixed to the middle of one end of the two sliders 12. The outer surface of the two sliders 12 is slidably connected to the inner wall of the two slide grooves 13. One end of the two brush holders 14 is fixed to the middle of the other end of the two sliders 12. The bristles of the two brush holders 14 are attached to the outer surfaces of both sides of the transparent frame 4.

[0036] In use, this invention works as follows: When the operator manually presses the two sealing plates 9, these plates, aided by a cleverly designed limiting mechanism constructed by the rotating frame 7 and the rotating groove 6, smoothly rotate around a specific axis point, thus opening the device. At this time, the drive frame 11, tightly connected to the sealing plates 9, shifts position as the plates rotate. Because the drive frame 11's movement path is firmly limited by the through groove 10, it can only move along the direction of the groove, thereby driving the slider 12, which is fixed to it, to slide in the opposite direction within the track set on the inner wall of the groove 13. This reverse sliding of the slider 12, in turn, drives the brush holder 14, which is firmly connected to it, to move away from each other. Under the linkage of this series of actions, the bristles on the two brush holders 14 gradually approach and contact the surface of the transparent frame 4. As they move away from each other, like two brooms, they gradually clean the dust and various tiny impurities accumulated on the surface of the transparent frame 4. Through this ingenious mechanical structure design, a good automatic cleaning effect is successfully achieved. Whenever staff open the closed panel 9 to view dashboard data, the cleaning process of the transparent frame 4 will start automatically. This eliminates the need for staff to spend extra time and effort preparing for the cleaning, greatly reducing their workload and improving the ease of use of the dashboard.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
