Description

Rain shielding device

Technical Field

The utility model relates to the technical field of electric cabinets, in particular to a rain shielding device.

Background

In the existing large-scale outdoor heating and ventilation system, an electric cabinet is used as a core component for controlling the operation of the whole equipment, and environmental factors, particularly the requirements of water resistance and moisture resistance, are usually considered in the design and manufacturing processes of the electric cabinet. Therefore, when the electric cabinet is in a closed state, by adopting specific sealing materials and structural designs, such as a waterproof sealing ring, a waterproof pad, a fastened box cover and the like, the electric cabinet can be ensured to reach a certain rainproof protection level (such as IP54 or higher in the IP level), rainwater is effectively prevented from intruding, and internal electric elements are protected from being influenced by moisture, so that the stable operation of the system is maintained, and the service life is prolonged.

However, when it is necessary to perform operations such as daily maintenance, regular maintenance, or emergency debugging on the electric cabinet, the electric cabinet cover must be opened. Once the electric cabinet is opened, the original sealing structure is destroyed, the rainproof protection level immediately fails, and the inside of the electric cabinet is directly exposed to the external environment. If the rainy weather is encountered at this moment, rainwater is easy to permeate into the electric cabinet through the opening part, so that not only can the electric elements be short-circuited and damaged, but also potential safety hazards such as electric shock can be caused, and the safety of maintenance personnel and the normal operation of equipment are seriously influenced.

For the above reasons, most of maintenance plans of outdoor heating and ventilation equipment at present avoid overcast and rainy weather, and the electric cabinet is opened on a sunny day to ensure the safety and effectiveness of work. Although the safety of equipment and personnel is guaranteed to a certain extent, the flexibility of maintenance work is limited, and particularly in continuous rainy seasons, the maintenance period is possibly prolonged, the risk of equipment failure is increased, and even the service quality and efficiency of the whole heating and ventilation system are affected.

There is therefore a need for a rain barrier that ameliorates the above-described problems.

In particular, the reinforcing rod 80 is designed such that the rotating connecting rod 40 can achieve a more labor-saving operation by the lever principle or the like when rotating the forward direction closing plate 20, which is particularly useful in the case where frequent rotation of the forward direction closing plate 20 is required. In addition, the reinforcing bar 80 is connected with the rotary connecting bar 40 and the forward direction sealing plate 20 to form a more stable supporting system, and the structure is more stable mechanically, so that deformation or damage caused by uneven stress or external interference can be prevented. In addition, through the transmission connection of the reinforcing rod 80, the rotating connecting rod 40 can more precisely control the rotating angle and position when driving the forward direction sealing plate 20 to rotate, which is particularly important for the occasion that the rotating angle of the forward direction sealing plate 20 needs to be precisely controlled.

In addition, since the rotary connecting rod 40 and the driven rod 90 are disposed in parallel, the electric component 30 can more precisely control the rotation angle and speed of the forward sealing plate 20 when driving the rotary connecting rod 40, and this precise control is particularly important for occasions where precise adjustment of the position of the forward sealing plate 20 is required, such as some automatic production lines or precise mechanical devices.

Referring to fig. 5 to 8, in one embodiment, the number of the reinforcing rods 80 is two, and the reinforcing rods are respectively located at both sides of the rotating connecting rod 40.

Specifically, by providing a reinforcing bar 80 on each side of the rotating connecting rod 40, a more stable supporting structure is formed, and this design helps to prevent the forward sealing plate 20 from shaking or deflection due to uneven stress or external interference during rotation, thereby improving the stability and reliability of rotation. In addition, the two reinforcing rods 80 are respectively located at two sides of the rotary connecting rod 40, so that stress in the rotation process can be dispersed more effectively, and the design of dispersing stress is beneficial to reducing the load of single components and prolonging the service life of the whole transmission system. In addition, the provision of the reinforcing rods 80 enhances the torsional capacity of the drive train, and the two reinforcing rods 80 provide additional support and stability when the rotating connecting rod 40 is subjected to torsional forces, preventing the system from being damaged by excessive torsional forces. In addition, the design of the two reinforcing rods 80 not only improves the stability of rotation, but also helps to optimize the transmission efficiency, so that the driving force of the electric component 30 can be more effectively converted into the rotational energy of the forward seal plate 20 by reducing friction and energy loss during rotation.

In addition, the connection between the locking protrusion 41 and the locking groove 81 is simple and effective, and has high stability, and the connection prevents the relative sliding or separation between the reinforcing rod 80 and the rotating connecting rod 40 during the rotation process, thereby improving the connection stability and reliability of the whole transmission system. In addition, the design of the clamping protrusion 41 and the clamping groove 81 makes the installation and the disassembly of the reinforcing rod 80 easier and more convenient, and the design not only reduces the installation cost, but also facilitates the rapid maintenance or replacement of the components when needed. In addition, by tightly coupling the reinforcing rod 80 with the rotating connecting rod 40, the structural strength of the entire transmission system is enhanced, which contributes to resistance to external loads and impacts, thereby improving the durability and service life of the system. In addition, due to the tight connection and synchronous movement between the reinforcing rod 80 and the rotary connecting rod 40, energy loss during transmission is minimized, and such optimization helps to improve transmission efficiency, so that the driving force of the electric component 30 can be more effectively converted into the rotational energy of the forward seal plate 20. In other embodiments, the rotatable connecting rod 40 may be provided with a clamping groove, and the reinforcing rod 80 is provided with a clamping protrusion corresponding to the clamping groove.

More specifically, the electric member 30 is a motor that forms a meshing transmission with the rotating connecting rod 40 through a gear set. The motor serves as a power source to transmit power to the rotating connecting rod 40 through the gear set, and the meshing transmission of the gear set ensures efficient transmission of power so that the rotating connecting rod 40 can rotate in a predetermined manner and speed. In addition, the efficiency of the gear engagement transmission is high, and the loss of energy in the transmission process can be reduced, which means that the power output by the motor can be more effectively converted into the rotation energy of the rotation connecting rod 40, thereby improving the efficiency of the whole transmission system.

Referring to fig. 5 to 8, in one embodiment, the number of telescopic cylinders 50 and the number of guide rails 60 are two, and are respectively located at two sides of the electric cabinet 100.

In addition, the guide rails 60 serve as guiding devices, so that the telescopic air cylinders 50 can move along a preset track in the lifting process, and the design of the two guide rails 60 further improves the guiding precision, so that the lifting of the upper sealing plate 10 is more accurate and stable. In addition, the arrangement of the two telescopic cylinders 50 enhances the bearing capacity of the lifting system, and the design can ensure that the upper sealing plate 10 is lifted stably and safely in the occasion of bearing a large load. In addition, the two telescopic cylinders 50 and the guide rails 60 are respectively arranged on two sides of the electric cabinet 100, so that the lifting stability is improved, the space layout of the whole system is optimized, the connection between all the components is more compact and reasonable, and the space waste is reduced.
