Description

Technical Field

[0001] The invention relates to the technical field of electric control boxes, and in particular to a rain shielding device. Background Art

[0002] In existing large-scale outdoor HVAC systems, the electric control box is the core component that controls the operation of the entire equipment. Environmental factors, especially the need for waterproofing and moisture-proofing, are usually taken into consideration during its design and manufacturing process. Therefore, when the electric control box is in a closed state, by adopting specific sealing materials and structural designs, such as waterproof sealing rings, waterproof pads, and a tight box cover, it can ensure that the electric control box reaches a certain rainproof protection level (such as IP54 or higher in the IP level), effectively prevent rainwater from intruding, and protect the internal electrical components from moisture, thereby maintaining the stable operation of the system and extending its service life.

[0003] However, when the electric control box needs to be repaired, maintained regularly, or debugged urgently, the cover of the electric control box must be opened. Once the electric control box is opened, the original sealing structure is destroyed, the rain protection level is invalidated, and the inside of the electric control box is directly exposed to the external environment. If it is rainy at this time, rainwater can easily penetrate into the electric control box through the opening, which may not only cause short circuit and damage to electrical components, but also cause safety hazards such as electric shock, seriously affecting the safety of maintenance personnel and the normal operation of equipment.

[0004] In view of the above reasons, most of the current maintenance plans for outdoor HVAC equipment will avoid rainy weather and choose to open the electric control box on sunny and dry days to ensure the safety and effectiveness of the work. Although this practice guarantees the safety of equipment and personnel to a certain extent, it also limits the flexibility of maintenance work, especially in continuous rainy seasons, which may lead to extended maintenance cycles, increased risk of equipment failure, and even affect the service quality and efficiency of the entire HVAC system.

[0005] Therefore, a rain shielding device is needed to improve the above problems. Summary of the invention

[0038] See also Figures 1 to 8 The specific embodiment shown in the invention discloses a rainproof device, comprising: an upper sealing plate 10, a forward sealing plate 20, an electric component 30, a rotating connecting rod 40 and a telescopic cylinder 50, wherein the telescopic cylinder 50 is installed on the side of the electric control box 100, the upper sealing plate 10 and the forward sealing plate 20 are located above the electric control box 100, and the upper sealing plate 10 is transmission-connected to the telescopic end of the telescopic cylinder 50, and the telescopic cylinder 50 drives the upper sealing plate 10 to rise and fall, the electric component 30 is installed on the upper sealing plate 10, the rotating connecting rod 40 is installed on the forward sealing plate 20, and the rotating connecting rod 40 is transmission-connected to the electric component 30; the electric component 30 drives the rotating connecting rod 40 to move, so that the forward sealing plate 20 forms an open or closed state.

[0039] Specifically, the upper sealing plate 10 and the forward sealing plate 20 are located above the electric control box 100, and the upper sealing plate 10 is transmission-connected to the telescopic end of the telescopic cylinder 50, the telescopic cylinder 50 drives the upper sealing plate 10 to rise and fall, the electric component 30 is installed on the upper sealing plate 10, the rotating connecting rod 40 is installed on the forward sealing plate 20, and the rotating connecting rod 40 is transmission-connected to the electric component 30, the electric component 30 drives the rotating connecting rod 40 to move, so that the forward sealing plate 20 is formed in an open or closed state, that is, a barrier is formed in the door opening direction of the electric control box 100 by the upper sealing plate 10 and the forward sealing plate 20, which effectively prevents rainwater from splashing into the interior of the electric control box 100 from above and the door opening direction, avoids damage to components, and also facilitates maintenance personnel to work in a rainy environment, so as to achieve the effect of being able to perform maintenance and debugging in a rainy environment. In addition, through the cooperation of the telescopic cylinder 50 and the electric component 30, the device can realize flexible adjustment of the upper sealing plate 10 and the forward sealing plate 20. The telescopic cylinder 50 can drive the upper sealing plate 10 to rise and fall to adapt to the debugging requirements of different heights; and the electric component 30 can drive the rotating connecting rod 40 to move, so that the forward sealing plate 20 switches between the open and closed states, which is convenient for maintenance personnel to debug and repair the electrical control box 100 in rainy environments.

[0040] See also Figures 1 to 8 As shown, in one embodiment, a guide rail 60 is further provided on the back side of the upper sealing plate 10 , and the upper sealing plate 10 is slidably connected to the guide rail 60 .

[0041] Specifically, the design of the guide rail 60 allows the upper cover plate 10 to have a fixed path and support during the lifting process, which helps prevent the upper cover plate 10 from shaking or deflecting during the lifting process. By slidingly connecting to the guide rail 60, the upper cover plate 10 can rise or fall more smoothly, ensuring its stability during operation. In addition, the guide rail 60 provides a precise guiding mechanism, allowing the upper cover plate 10 to accurately reach a predetermined position, which is particularly important for application scenarios that require precise control of the height of the upper cover plate 10. In addition, the sliding connection between the guide rail 60 and the upper cover plate 10 reduces direct friction and wear, thereby extending the service life of the upper cover plate 10 and the entire rain shielding device. In addition, the smooth lifting process also helps to reduce equipment damage caused by impact or vibration.

[0042] See also Figures 1 to 5 , Figure 7 and Figure 8 As shown, in one embodiment, the guide rail 60 is further slidably connected to a support member 70, and one end of the support member 70 away from the guide rail 60 is connected to the telescopic end.

[0043] Specifically, a stable support structure is formed by the sliding connection between the support member 70 and the guide rail 60. This structure can effectively prevent shaking or deviation caused by uneven force or external interference when the telescopic end is lifted or lowered. In addition, the introduction of the support member 70 makes the lifting and lowering movement of the telescopic end more controllable, reducing the noise and vibration that may be generated due to unstable movement. In addition, due to the introduction of the support member 70, the structure of the entire lifting device is more stable, reducing the risk of failure caused by structural instability. At the same time, the sliding connection of the support member 70 also reduces the performance degradation caused by friction and wear, and improves the reliability and durability of the entire device.

[0044] Preferably, the support member 70 is provided with a U-shaped buckle, and the U-shaped buckle is connected to the telescopic end.

[0045] Specifically, the design of the U-shaped buckle allows for flexible adjustment of its position on the telescopic end, which means that in actual applications, the U-shaped buckle can be adjusted to the optimal position of the telescopic end according to specific needs to ensure that the connection between the support member 70 and the telescopic end is both stable and meets the use requirements. In addition, as a connecting device, the U-shaped buckle has a compact and stable structure. When it is correctly installed on the telescopic end, it can effectively prevent the telescopic end from shaking during the lifting process, thereby enhancing the connection stability of the entire lifting system. In addition, the installation of the U-shaped buckle is usually relatively simple and does not require complex tools or equipment; at the same time, due to its structural characteristics, the U-shaped buckle can also be easily disassembled and reinstalled when necessary, which is conducive to the daily maintenance and maintenance of the lifting system.

[0046] See also Figures 1 to 8 As shown, in one embodiment, the rotating connecting rod 40 is also transmission-connected to a reinforcing rod 80 , and one end of the reinforcing rod 80 away from the rotating connecting rod 40 is connected to the positive sealing plate 20 .

[0047] Specifically, the design of the reinforcing rod 80 enables the rotating connecting rod 40 to achieve a more labor-saving operation through the lever principle or a similar mechanism when driving the forward sealing plate 20 to rotate. This design is particularly useful in situations where the forward sealing plate 20 needs to be rotated frequently. In addition, the connection between the reinforcing rod 80, the rotating connecting rod 40 and the forward sealing plate 20 forms a more stable support system. This structure is more stable in mechanics and can prevent deformation or damage caused by uneven force or external interference. In addition, through the transmission connection of the reinforcing rod 80, the rotating connecting rod 40 can more accurately control the angle and position of rotation when driving the forward sealing plate 20 to rotate, which is particularly important for situations where the rotation angle of the forward sealing plate 20 needs to be accurately controlled. In addition, the use of the reinforcing rod 80 can disperse the force on the rotating connecting rod 40 and the forward sealing plate 20 during the rotation process, reducing wear and damage caused by concentrated force.

[0048] See also Figures 1 to 8 As shown, in one embodiment, the positive sealing plate 20 is provided with a driven rod 90 corresponding to the reinforcing rod 80 , and the reinforcing rod 80 is fixed to the driven rod 90 .

[0049] Specifically, by setting the driven rod 90 and fixing the reinforcing rod 80 on the driven rod 90, forming a parallel state with the rotating connecting rod 40, an efficient lever system is constructed. This design enables the electric component 30 to use the lever principle to achieve a larger rotation of the forward sealing plate 20 with a smaller driving force when driving the rotating connecting rod 40, thereby significantly reducing the force required during operation and improving work efficiency. In addition, the fixed connection between the reinforcing rod 80 and the driven rod 90, and the parallel arrangement of the rotating connecting rod 40 and the driven rod 90 form a stable support structure, which enhances the structural stability of the entire transmission system. This design helps to prevent deformation or damage caused by uneven force or external interference, and improves the reliability and durability of the system. In addition, since the rotating connecting rod 40 and the driven rod 90 are arranged in a parallel state, the electric component 30 can more accurately control the rotation angle and speed of the forward sealing plate 20 when driving the rotating connecting rod 40. This precise control is particularly important for occasions where the position of the forward sealing plate 20 needs to be accurately adjusted, such as in some automated production lines or precision mechanical devices.

[0050] See also Figures 5 to 8 As shown, in one embodiment, the number of the reinforcing rods 80 is two, and they are respectively located on both sides of the rotating connecting rod 40 .

[0051] Specifically, by providing a reinforcing rod 80 on each side of the rotating connecting rod 40, a more stable support structure is formed. This design helps to prevent the forward sealing plate 20 from shaking or deflecting due to uneven force or external interference during the rotation process, thereby improving the stability and reliability of the rotation. In addition, the two reinforcing rods 80 are respectively located on both sides of the rotating connecting rod 40, which can more effectively disperse the force during the rotation process. This design of dispersing the force helps to reduce the load of a single component and extend the service life of the entire transmission system. In addition, the provision of the reinforcing rod 80 enhances the torsion resistance of the transmission system. When the rotating connecting rod 40 is subjected to a torsional force, the two reinforcing rods 80 can provide additional support and stability to prevent the system from being damaged due to excessive torsional force. In addition, the design of the two reinforcing rods 80 not only improves the stability of the rotation, but also helps to optimize the transmission efficiency. By reducing the friction and energy loss during the rotation process, the driving force of the electric component 30 can be more effectively converted into the rotational energy of the forward sealing plate 20.

[0052] See also Figure 8As shown, in one embodiment, the rotating connecting rod 40 is provided with a clamping protrusion 41 , and the reinforcing rod 80 is provided with a clamping groove 81 corresponding to the clamping protrusion 41 .

[0053] Specifically, by providing the engaging protrusion 41 on the rotating connecting rod 40 and providing the corresponding engaging groove 81 on the reinforcing rod 80, a reliable connection mechanism is realized. This design ensures that when the rotating connecting rod 40 rotates, the reinforcing rod 80 can closely follow and move synchronously with it. This synchronous movement is essential for ensuring the accurate rotation of the positive sealing plate 20. In addition, the connection mode of the engaging protrusion 41 and the engaging groove 81 is not only simple and effective, but also has high stability. This connection mode can prevent the relative sliding or disengagement between the reinforcing rod 80 and the rotating connecting rod 40 during the rotation process, thereby improving the connection stability and reliability of the entire transmission system. In addition, the design of the engaging protrusion 41 and the engaging groove 81 makes the installation and removal of the reinforcing rod 80 simpler and more convenient. This design not only reduces the installation cost, but also helps to quickly maintain or replace parts when necessary. In addition, by closely connecting the reinforcing rod 80 with the rotating connecting rod 40, the structural strength of the entire transmission system is enhanced, and this enhancement helps to resist external loads and impacts, thereby improving the durability and service life of the system. In addition, due to the close connection and synchronous movement between the reinforcing rod 80 and the rotating connecting rod 40, the energy loss in the transmission process is minimized. This optimization helps to improve the transmission efficiency, so that the driving force of the electric component 30 can be more effectively converted into the rotational energy of the positive sealing plate 20. In other embodiments, the rotating connecting rod 40 can also be provided with a card slot, and the reinforcing rod 80 can be provided with a card connection protrusion corresponding to the card slot.

[0054] More specifically, the electric component 30 is a motor, which forms a meshing transmission with the rotating connecting rod 40 through a gear set. The motor, as a power source, transmits power to the rotating connecting rod 40 through the gear set, and the meshing transmission of the gear set ensures the effective transmission of power, so that the rotating connecting rod 40 can rotate in a predetermined manner and speed. In addition, the gear meshing transmission has a high efficiency and can reduce the loss of energy during the transmission process, which means that the power output by the motor can be more effectively converted into the rotational energy of the rotating connecting rod 40, thereby improving the efficiency of the entire transmission system.

[0055] See also Figures 5 to 8 As shown, in one embodiment, the number of the telescopic cylinder 50 and the number of the guide rail 60 are both two, and they are respectively located on both sides of the electric control box 100 .

[0056] Specifically, by arranging a telescopic cylinder 50 and a guide rail 60 on both sides of the electric control box 100, a more stable lifting support structure is formed. This design helps to prevent shaking or deflection caused by uneven force or external interference during the lifting process, thereby improving the stability and reliability of the lifting. In addition, the two telescopic cylinders 50 and the two guide rails 60 are respectively located on both sides of the electric control box 100, which can more effectively disperse the force during the lifting process. This design of dispersing force helps to reduce the load of a single component and extend the service life of the entire lifting system. In addition, the guide rail 60, as a guiding device, can ensure that the telescopic cylinder 50 moves along a predetermined trajectory during the lifting process. The design of the two guide rails 60 further improves the guiding accuracy, making the lifting of the upper sealing plate 10 more accurate and stable. In addition, the provision of the two telescopic cylinders 50 enhances the carrying capacity of the lifting system. In situations where a large load needs to be borne, this design can ensure that the upper sealing plate 10 is lifted and lowered smoothly and safely. In addition, arranging the two telescopic cylinders 50 and the guide rails 60 on both sides of the electric control box 100 not only improves the lifting stability, but also helps to optimize the spatial layout of the entire system. This layout makes the connection between the various components more compact and reasonable, reducing space waste.

[0057] In one embodiment, the rotation angle of the positive sealing plate 20 is 0-80 degrees.

[0058] Specifically, by adjusting the rotation angle of the forward sealing plate 20, the rain shielding range of the electric control box 100 can be precisely controlled. This design ensures that the forward sealing plate 20 can provide the best rain shielding protection for the electric control box 100 under different weather conditions to prevent rainwater from invading and causing damage. In addition, factors such as wind direction, rainfall and rain intensity in the natural environment will affect the rain shielding effect. By allowing the forward sealing plate 20 to rotate within the range of 0-80 degrees, its angle can be flexibly adjusted to adapt to different environmental conditions to ensure that the electric control box 100 is always in the best rain shielding state. In addition, rainwater intrusion into the electric control box 100 may cause serious consequences such as circuit short circuit, equipment damage and even fire. By optimizing the rotation angle of the forward sealing plate 20, these potential risks can be effectively prevented and the safety and reliability of the electric control box 100 can be improved. In addition, allowing the forward sealing plate 20 to adjust its angle as needed enhances the adaptability and flexibility of the entire device. This design enables the device to better cope with different environments and operating requirements, and improves its overall performance and reliability.

[0059] In one embodiment, the electric control box 100 is provided with a plurality of box doors 101 , and the box doors 101 are connected with hydraulic components 102 .

[0060] Specifically, when the door 101 of the electric control box 100 is opened, the hydraulic component 102 starts to work and provides stable support for the door 101. This support ensures that the door 101 will not shake due to gravity or external factors when it is open, thereby ensuring the stability and safety of the door 101. In addition, the shaking of the door 101 may affect the operation of the maintenance personnel and even cause safety hazards. The hydraulic component 102 provides stable support, which can eliminate the adverse effects of the shaking of the door 101 and create a safer and more stable working environment for the maintenance personnel. In addition, the stable support of the door 101 allows the maintenance personnel to operate more conveniently without worrying about the interference caused by the shaking of the door 101, which helps to improve maintenance efficiency, shorten maintenance time, and reduce maintenance costs. In addition, the use of the hydraulic component 102 can reduce the wear and impact of the door 101 during the opening and closing process, thereby extending the service life of the electric control box 100 and its components, which is particularly important for the electric control box 100 that is operated for a long time and frequently maintained.

[0061] In one embodiment, the upper sealing plate 10 and the forward sealing plate 20 are both made of metal.

[0062] Specifically, metal has excellent strength and durability, and can withstand greater external forces and pressures. Therefore, the upper sealing plate 10 and the positive sealing plate 20 made of metal can ensure that they are not easily damaged during use and have a longer service life. In addition, the upper sealing plate 10 and the positive sealing plate 20 made of metal can provide better protection capabilities. They can effectively block external impacts, collisions and erosion, and protect the electric control box 100 and its internal components from damage. In addition, metal materials are easy to process and manufacture, and can meet the needs of various complex shapes and sizes. This allows the upper sealing plate 10 and the positive sealing plate 20 made of metal to accurately adapt to the structural and design requirements of the electric control box 100, ensuring the accuracy and reliability of the installation.

[0063] The working principle of the rainproof device is as follows: the electric component 30 provides power to drive the rotating connecting rod 40 to rotate, and the rotating connecting rod 40 drives the driven rod 90 through the reinforcing rod 80. Since the driven rod 90 is connected to the positive sealing plate 20 as a whole, the rotation angle of the rotating connecting rod 40 is synchronously reflected on the positive sealing plate 20, that is, the positive sealing plate 20 rotates from the vertical direction to the horizontal direction by a certain angle. In addition, since the upper sealing plate 10 is rigidly connected to the telescopic cylinder 50, the upper sealing plate 10 is driven to move downward through the telescopic end (since the upper sealing plate 10 is connected to the positive sealing plate 20, it will move downward as a whole), thereby forming an overall downward movement, and then cooperating with the box door 101 of the opened electrical control box 100, an effective rainproof function is formed, which is convenient for maintenance personnel to carry out maintenance, inspection and debugging, and greatly reduces the influence of external environmental factors on maintenance work. After the inspection is completed, the device returns to the original route to achieve reset.

[0064] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
