[0020] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0021] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0022] This embodiment discloses Figures 1 to 7 The moisture-proof distribution switch cabinet with lifting function shown in the figure includes a mounting base 1 and a switch cabinet body 2 mounted on the top surface thereof. A cabinet door 3 is hinged to one side of the switch cabinet body 2 through a hinge, and a dry moisture-proof pad 21 is embedded in the inner bottom wall of the switch cabinet body 2.

[0023] Specifically, the interior of the mounting base 1 is provided with a stepped inner cavity that is narrow at the top and wide at the bottom. A lifting support plate 14 is provided at the bottom of the stepped inner cavity. A lifting positioning block 10 is provided at the upper part of the stepped inner cavity. A hydraulic lifting column 12 is provided between the lifting support plate 14 and the lifting positioning block 10. The upper part of the lifting positioning block 10 is fixedly connected to the switch cabinet body 2. The stepped inner cavity includes an upper positioning chamber 5 and a lower positioning chamber 6. The lifting positioning block 10 is adapted to be positioned in the upper positioning chamber 5, and the lifting support plate 14 is adapted to be positioned in the lower positioning chamber 6. The bottom surface of the mounting base 1 is provided with a lifting support plate 14. A removable base plate 13 is installed with bolts, and a motor 15 is installed on one side of the top surface of the removable base plate 13. The longitudinal output shaft of the motor 15 is longitudinally connected to a threaded rod 16, and the threaded rod 16 longitudinally penetrates the lifting support plate 14. The top end of the threaded rod 16 is rotatably connected to the inner top wall of the positioning lower chamber 6. A plurality of positioning vertical rods 17 are symmetrically welded on the edge side of the top surface of the removable base plate 13. The top ends of the plurality of positioning vertical rods 17 all longitudinally penetrate the lifting support plate 14 and are fixedly connected to the inner top wall of the positioning lower chamber 6. A removable inspection window 7 is installed on the outer wall of one side of the mounting base 1 by screws.

[0024] Specifically, the starting motor 15 drives the lifting support plate 14 to rise or fall through threaded transmission, thereby driving the switch cabinet body 2 to realize the lifting action. In order to enhance the structural stability, the top edge of the removable bottom plate 13 is symmetrically welded with multiple positioning rods 17. The top ends of the multiple positioning rods 17 all penetrate the lifting support plate 14 longitudinally and are fixedly connected to the top wall of the positioning lower chamber 6, forming an effective guide and support for the lifting support plate 14.

[0025] Specifically, the present invention utilizes a stepped internal cavity design, divided into an upper positioning chamber 5 and a lower positioning chamber 6, which accommodate a lifting and positioning block 10 and a lifting support plate 14, respectively. Compared to traditional single-stage lifting methods, this two-stage lifting structure significantly increases the overall lifting range, enabling the distribution switchgear to be adjusted significantly in height to meet the needs of the actual application environment, such as adapting to different floors, different equipment heights, or special maintenance requirements. This feature greatly expands the device's application range and improves its applicability and flexibility in various engineering projects.

[0026] Specifically, the inner walls on both sides of the switch cabinet body 2 are respectively provided with a dehumidifying blower fan 31 and a dehumidifying exhaust fan 22. The output end of the dehumidifying blower fan 31 is provided with an outer air guide arc plate 32 and an inner air guide arc plate 33 for guiding the wind direction. The input end of the dehumidifying exhaust fan 22 is provided with an adsorption cotton block 20 for adsorbing humid air and moisture and an electric heating plate 26 for drying the adsorption cotton block 20.

[0027] Specifically, the symmetrical installation of the dehumidifying blower fan 31 and the dehumidifying exhaust fan 22 ensures even airflow distribution, effectively dissipating moisture within the cabinet. The dehumidifying exhaust fan 22 is equipped with an adsorbent pad 20 and an electric heater 26 at its input. The former absorbs humid air and moisture, while the latter dries the adsorbent pad 20, ensuring it maintains its excellent moisture absorption capacity.

[0028] Specifically, the dehumidifying fan 31 continuously blows air, effectively stirring the air inside the cabinet, promoting air circulation and reducing localized moisture accumulation. The arrangement of the outer curved air guide plate 32 and the inner curved air guide plate 33 ensures uniform distribution of airflow, preventing uneven cooling or vibration of electrical components caused by concentrated wind. The filter 30 prevents external dust from entering the cabinet, protecting electrical equipment from contamination.

[0029] Specifically, ventilation mesh panels 4 are installed on both side outer walls of the switch cabinet body 2 by screws, a filter screen 30 is arranged between the dehumidifying fan 31 and the adjacent ventilation mesh panels 4, the outer air guide arc panels 32 are symmetrically installed on the two side edges of the output end of the dehumidifying fan 31, and the inner air guide arc panels 33 are symmetrically arranged between the two outer air guide arc panels 32. The dehumidifying exhaust fan 22 is installed in the U-shaped box body 18. The side surface of the U-shaped box body 18 that is close to the inner wall of the switch cabinet body 2 has an exhaust mesh hole, and the free end of the U-shaped box body 18 is provided with a mounting frame 24.

[0030] Specifically, a support grid 25 is provided on the side of the mounting frame 24 close to the dehumidification exhaust fan 22, and the adsorption cotton block 20 is fixed on the side of the mounting frame 24 facing away from the dehumidification exhaust fan 22. The electric heating plate 26 is arranged between the adsorption cotton block 20 and the support grid 25. The top surface of the free end of the U-shaped box body 18 and the top surface of the mounting frame 24 are both provided with a plug-in interface 23 for plugging in the electric heating plate 26. An electric heating plate storage cavity 19 is fixed on the top surface of the U-shaped box body 18. The electric heating plate storage cavity 19 has a U-shaped structure and is connected to the inner wall of the switch cabinet body 2 to form an inner cavity capable of storing the electric heating plate 26. A pull ring 27 is fixed on the top surface of the electric heating plate 26. The pull ring 27 is used to plug in and unplug the electric heating plate 26. Snap-in protrusions 28 are symmetrically fixed on both sides of the plug-in interface 23 and located on the top surface of the mounting frame 24. The snap-in protrusions 28 are snapped into the inner top wall of the U-shaped box body 18, thereby fixing and detachably installing the mounting frame 24.

[0031] Specifically, the dehumidification exhaust fan 22 is located in an area of the cabinet where moisture easily accumulates and is responsible for extracting moisture from the cabinet. It is installed in the U-shaped box 18. The U-shaped box's exhaust mesh design facilitates rapid moisture discharge and prevents moisture backflow. The adsorbent cotton block 20 is located at the input end of the dehumidification exhaust fan 22 and deeply absorbs the passing air, effectively capturing moisture and some moisture in the air. Its high hygroscopicity ensures that the humidity in the cabinet is effectively reduced. The electric heater 26 is located between the adsorbent cotton block 20 and the support grid 25. It periodically or continuously heats the adsorbent cotton block, prompting the adsorbed moisture to evaporate and restore its moisture absorption capacity. The electric heater is connected to the power supply through the bracket port 23, making it easy to install and replace.

[0032] Specifically, a sealing top cover 11 is integrally formed on the top surface of the lifting and positioning block 10, and a rubber sealing ring 9 is embedded in the top surface of the mounting base 1. The sealing top cover 11 presses down the rubber sealing ring 9 to achieve sealing of the mounting base 1. A sealing inner groove 8 for installing the rubber sealing ring 9 is provided on the top surface of the mounting base 1. In addition, when the switch cabinet body 2 is in a lowered state, the sealing top cover 11 presses down the rubber sealing ring 9 to achieve sealing of the mounting base 1, effectively preventing external moisture from entering through the gap between the base and the switch cabinet, thereby further improving the moisture-proof effect.

[0033] How it works This moisture-proof distribution switchgear with a lifting function, when the switchgear body 2 needs to be lifted in the first level, the hydraulic lifting column 12 drives the lifting and positioning block 10 to lift and adjust the required height in the positioning upper chamber 5. When the second level of lifting is required, the motor 15 drives the threaded rod 16 to rotate, and the threaded rod 16 rotates in the positioning lower chamber 6 through the bearing, and then cooperates with the use of the positioning vertical rod 17 to drive the lifting support plate 14 to lift and lower in the positioning lower chamber 6 in the second level, thereby meeting the needs of different lifting heights. The dehumidifying fan 31 stirs the air in the cabinet by blowing continuously, promotes air circulation, and reduces local moisture accumulation. The arrangement of the outer air guide arc plate 32 and the inner air guide arc plate 33 ensures the uniform distribution of the blowing direction. The dehumidifying exhaust fan 22 is responsible for extracting the moisture in the cabinet. The adsorption cotton block 20 is located at the input end of the dehumidifying exhaust fan 22, deeply adsorbs the passing air, captures the moisture and partial moisture in the air, and the electric heating plate 26 periodically or continuously heats the adsorption cotton block 20 to promote the evaporation of the adsorbed moisture and restore its moisture absorption capacity.
