[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a multifunctional electrical control cabinet includes: a cabinet body 10, the inner cavity of which is used to house electrical structures; a moisture-absorbing structure 20, which is disposed at the bottom of the cabinet body 10; the moisture-absorbing structure 20 contains a desiccant; the moisture-absorbing structure 20 is slidable relative to the cabinet body 10; a moisture-proof structure 30, which is disposed at the top of the cabinet body and is used to prevent rainwater from falling on the cabinet body 10; and a mounting base 40, on which the cabinet body 10 is mounted, and which is used to assist in the installation and fixation of the cabinet body 10. When the desiccant is replaced, the moisture-absorbing structure 20 extends out of the cabinet 10 and isolates the inner cavity of the cabinet 10 from the external environment.

[0022] Specifically, the multifunctional electrical control cabinet in this application includes a cabinet body 10, a moisture-absorbing structure 20, a moisture-proof structure 30, and a mounting base 40. The inner cavity of the cabinet body 10 is used to house the electrical structure. The moisture-absorbing structure 20 is located at the bottom of the cabinet body 10, contains a desiccant, and is movable relative to the cabinet body 10; the moisture-proof structure 30 is located at the top of the cabinet body 10 to prevent rainwater from falling on the cabinet body 10; the mounting base 40 is used to support the cabinet body 10 and assist in its installation and fixation. The moisture-absorbing structure 20 is located inside the cabinet 10 during normal use and performs its moisture-absorbing function. When the desiccant needs to be replaced, the moisture-absorbing structure 20 can be moved out of the cabinet 10. At this time, the moisture-absorbing structure 20 isolates the inner cavity of the cabinet 10 from the external environment and prevents external moisture from entering during the replacement process. The moisture-proof structure 30 is independently set on the top of the cabinet 10 and forms an internal and external protection division with the moisture-absorbing structure 20, respectively dealing with the intrusion of rainwater and air moisture. The mounting base 40 is used to help to firmly connect the cabinet 10 to the external foundation structure such as the distribution box bracket, equipment installation platform or concrete base, so as to facilitate the fixation of the cabinet 10. In this application, when the desiccant is replaced, the moisture-absorbing structure 20 extends out of the cabinet 10 and simultaneously isolates the internal cavity from the external environment. The desiccant replacement can be completed without opening the cabinet door 12, effectively preventing moisture from entering the cabinet 10 and reducing the risk of moisture damage to the internal electrical structure. The moisture-proof structure 30, through the cooperation of the rainproof roof 32 and the support column 31, further enhances the waterproof performance while maintaining the cabinet 10's conventional moisture-absorbing function. On the one hand, it effectively blocks rainwater from directly invading the top of the cabinet; on the other hand, it provides an operating space independent of the external environment for maintenance work. This design significantly improves the reliability of electrical equipment protection in harsh environments such as high humidity and heavy rain.

[0023] In one possible implementation, the cabinet 10 includes: a frame 11 with an open side; the frame includes a first side panel 111 and a second side panel 112 disposed opposite to each other; a cabinet door 12 hinged to the frame 11 and disposed at the open side; and a multi-layer partition 13 horizontally disposed inside the frame 11, with multiple sets of through holes provided on the partition 13, the partition 13 being used to house electrical structures. The moisture-absorbing structure 20 is slidably disposed at the bottom of the first side plate 111 and the second side plate 112.

[0024] Specifically, the cabinet 10 consists of a frame 11, a cabinet door 12, and multiple partitions 13. The frame 11 has an opening on one side, serving as the main passage for equipment installation, inspection, maintenance, and daily operation. A first side panel 111 and a second side panel 112 are respectively installed on both sides of the frame 11. The cabinet door 12 is hinged to the opening of the frame 11, allowing it to rotate relative to the frame 11, facilitating opening and closing of the cabinet and enabling routine maintenance and equipment replacement. The multiple partitions 13 are vertically spaced along the interior of the cabinet 10, with each partition 13 horizontally installed inside the frame 11. The two ends of each partition 13 are fixed to the first side panel 111 and the second side panel 112, forming a layered electrical structure placement space. Multiple sets of through holes on the partitions 13 not only promote air circulation and optimize heat dissipation but also facilitate the connection of cables between electrical equipment, improving wiring efficiency. The moisture-absorbing structure 20 is slidably disposed at the bottom of the first side panel 111 and the second side panel 112, so that it can be easily removed from the cabinet for desiccant replacement when needed, avoiding the problem of moisture intrusion caused by opening the cabinet door.

[0025] In one possible implementation, the moisture-absorbing structure 20 includes a first moisture-absorbing structure 21 and a second moisture-absorbing structure 22, which have the same structure and are respectively disposed at the bottom of the first side plate 111 and the second side plate 112. The first moisture-absorbing structure 21 includes: A push-pull structure 211 is slidably disposed in an opening at the bottom of the first side plate 111; The desiccant holding structure 212 is placed in the push-pull structure 211; the desiccant holding structure 212 is used to hold the desiccant. When the sliding structure 211 is pushed into the cabinet 10, the desiccant holding structure 212 is located inside the cabinet 10, and the sliding structure 211 isolates the inner cavity of the cabinet 10 from the external environment; when the sliding structure 211 extends out of the cabinet 10, the desiccant holding structure 212 is located outside the cabinet 10, and the sliding structure 211 still isolates the inner cavity of the cabinet 10 from the external environment.

[0026] Specifically, the moisture-absorbing structure 20 consists of a first moisture-absorbing structure 21 and a second moisture-absorbing structure 22 with identical structures, respectively installed at the bottom of the first side plate 111 and the second side plate 112. Each moisture-absorbing structure includes a push-pull structure 211 and a desiccant holding structure 212: the push-pull structure 211 is slidably embedded in the opening at the bottom of the side plate, serving as a moving carrier; the desiccant holding structure 212 is placed inside the push-pull structure 211 to hold the desiccant. The two work together to achieve the functions of moisture absorption and isolation.

[0027] When the push-pull structure 211 is fully pushed into the cabinet 10, the desiccant holding structure 212 is located inside the cabinet 10 and plays a moisture-absorbing role. At the same time, the push-pull structure 211 seals the opening at the bottom of the first side panel 111, blocking the airflow between the inner cavity of the cabinet 10 and the external environment. When the desiccant needs to be replaced, the push-pull structure 211 is pulled out. At this time, the desiccant holding structure 212 is moved outside the cabinet 10 for easy operation, while the push-pull structure 211 still isolates the inner cavity of the cabinet 10 from the external environment, ensuring that moisture cannot enter the interior of the cabinet 10 during the replacement process, thus avoiding moisture intrusion during the replacement process.

[0028] In one possible implementation, the push-pull structure 211 includes: Placement box 2111, which is a square body with an open top, is used to place the desiccant holding structure 212. The sealing structure includes an inner sealing plate 2112 and an outer sealing plate 2113 symmetrically arranged on both sides of the placement box 2111; The limiting structure includes an inner baffle 2114 and an outer baffle 2115 respectively disposed on the outer side of the inner sealing plate 2112 and the outer sealing plate 2113; the inner baffle 2114 is located inside the cabinet 10, and the outer baffle 2115 is located outside the cabinet 10; the dimensions of the inner baffle 2114 and the outer baffle 2115 are larger than the dimensions of the bottom opening of the first side plate 111; A guide structure is provided, which vertically penetrates the first side plate 111 and is located on both sides of the bottom opening of the first side plate 111; the guide structure connects the inner baffle 2114 and the outer baffle 2115. When the push-pull structure 211 is pushed into the cabinet 10, the outer baffle 2115 is locked on the outside of the first side panel 111, and the outer sealing plate 2113 is matched with the opening section at the bottom of the first side panel 111; when the push-pull structure 211 extends out of the cabinet 10, the inner baffle 2114 is locked on the inside of the first side panel 111, and the inner sealing plate 2112 is matched with the opening section at the bottom of the first side panel 111.

[0029] Specifically, the push-pull structure 211 consists of a placement box 2111, a sealing structure, a limiting structure, and a guide structure. The placement box 2111 is a square body with an open top, used to accommodate the desiccant container structure 212; the sealing structure includes an inner sealing plate 2112 and an outer sealing plate 2113 symmetrically arranged on both sides of the placement box 2111, the inner sealing plate 2112 and the outer sealing plate 2113 matching the cross-sectional dimensions of the opening to achieve a sealing function; the limiting structure consists of an inner baffle 2114 and an outer baffle 2115, located on the inner and outer sides of the cabinet 10 respectively, and its size is larger than the bottom opening of the first side plate 111, used to limit the push-pull stroke; the guide structure vertically penetrates the first side plate 111 and is fixed on both sides of the opening, connecting the inner baffle 2114 and the outer baffle 2115 to ensure a smooth and precise push-pull process.

[0030] When the sliding structure 211 is fully pushed into the cabinet 10, the outer baffle 2115 is engaged with the outer edge of the first side panel 111. At this time, the outer sealing plate 2113 fits tightly with the cross-section of the bottom opening of the first side panel 111, forming a sealing barrier. In this state, the desiccant holding structure 212 is located inside the cabinet and performs its moisture absorption function. At the same time, the bottom opening of the first side panel 111 is sealed by the outer sealing plate 2113, blocking the flow of air between the inside and outside.

[0031] When the push-pull structure 211 is pulled outward, the inner baffle 2114 engages with the inner side of the first side panel 111, restricting further outward movement of the push-pull structure 211. The inner side of the first side panel 111 forms the inner cavity of the cabinet 10. At this time, the inner sealing plate 2112 fits tightly with the cross-section of the bottom opening of the first side panel 111, completely sealing the opening. In this state, the desiccant container 212 moves outside the cabinet 10 for easy replacement, while the bottom opening of the first side panel 111 is sealed by the inner sealing plate 2112, ensuring complete isolation between the inner cavity of the cabinet and the external environment.

[0032] In one possible implementation, the desiccant holding structure 212 includes: The desiccant container 2121 is a square frame with an open top. The external dimensions of the desiccant container 2121 match the internal cavity of the placement box 2111, and it can be freely removed from the placement box 2111. Two sets of ear plates 2122 are symmetrically arranged on the inner side wall of the desiccant container and extend into the interior of the desiccant container 2121; the two sets of ear plates 2122 are used to assist in the placement and removal of the desiccant container 2121.

[0033] Specifically, the desiccant container 2121 is a square frame with an open top. Its external dimensions are similar to and match the internal cavity of the placement box 2111. When used together, the desiccant container 2121 can be stably placed inside the placement box 2111 without significant shaking, and can be freely removed and placed. Two sets of ear plates 2122 are symmetrically arranged on the inner side wall of the desiccant container 2121 and extend towards the desiccant container 2121, serving as operating leverage points. This allows operators to easily remove and place the desiccant container 2121 by gripping the ear plates 2122, improving maintenance efficiency.

[0034] In one possible implementation, the bottom of the inner baffle 2114 is attached to the upper surface of the bottom plate of the cabinet 10.

[0035] Specifically, the bottom of the inner baffle 2114 is closely fitted to the upper surface of the bottom plate of the cabinet 10, so that the push-pull structure 211 remains stable when it is pushed into the cabinet 10 along the bottom plate, avoiding shaking during the push-pull process due to the gap between the inner baffle 2114 and the bottom plate, thereby ensuring the smoothness of the push-pull action and the accuracy of the positioning.

[0036] In one possible implementation, the bottom of the first side plate 111 is further provided with two through holes, which are located on both sides of the bottom opening of the first side plate 111, and the guide structure includes: Two guide rods 2116, each guide rod passing through a corresponding through hole, and the two ends of each guide rod 2116 are respectively connected to the inner baffle 2114 and the outer baffle 2115.

[0037] Specifically, the two through holes at the bottom of the first side plate 111 provide installation channels for the guide rods 2116. The two guide rods 2116 pass through the corresponding through holes, and the two ends of each guide rod 2116 are fixedly connected to the inner baffle 2114 and the outer baffle 2115, respectively. During the push-pull process, the guide rods 2116 slide along the direction of the through holes. The through holes restrict the movement trajectory of the guide rods 2116, ensuring that the push-pull structure 211 moves smoothly in a straight line, accurately controlling the push-in and push-out strokes, and preventing deviation or tilting during the push-pull process, thereby improving the stability and reliability of the operation.

[0038] In one possible implementation, a handle 2117 is provided on the outer baffle 2115.

[0039] Specifically, the handle 2117 provided on the outer baffle 2115 provides a gripping part for the operator, making it easier to pull or push the push-pull structure 211, making the push-pull process more labor-saving and convenient, and improving operating efficiency.

[0040] In one possible implementation, the mounting base 40 includes: Mounting plate 41 is located at the bottom of cabinet 10, and multiple mounting holes are provided around the mounting plate 41. The mounting holes are used to engage with fasteners to secure the cabinet 10.

[0041] Specifically, the mounting base 40 is composed of a mounting plate 41, which is located at the bottom of the cabinet 10. Multiple mounting holes are opened around the base for use with bolts, screws and other fasteners to firmly connect the cabinet 10 to the mounting base such as a bracket, ground or wall, ensuring that the cabinet 10 is installed stably, providing a stable operating environment for the internal electrical equipment, and facilitating on-site installation, disassembly and maintenance.

[0042] In one possible implementation, the moisture-proof structure 30 includes: Support column 31 is installed at the top of cabinet 10; Rain shelter 32 is installed on top of support column 31 and completely covers the top of cabinet 10.

[0043] Specifically, the support column 31 is fixed to the top of the cabinet 10 to provide stable support, and the rainproof roof 32 is installed on top of the support column 31 and completely covers the top of the cabinet 10, forming a rainproof barrier. This effectively prevents rainwater from directly hitting the cabinet 10, preventing rainwater from penetrating or accumulating on the top of the cabinet, avoiding damage to the electrical structure due to moisture, and improving the protective performance of the cabinet 10 in outdoor or humid environments. The following embodiments further illustrate this solution.

[0044] A multifunctional electrical control cabinet includes a cabinet body 10, with a cabinet door 12 rotatably connected to the front end of the cabinet body 10. Openings are provided below the left and right side panels of the cabinet body 10, namely the first side panel and the second side panel. A moisture-absorbing structure 20 is installed inside each opening. The moisture-absorbing structure 20 includes an outer sealing plate 2113, an outer baffle 2115 fixedly connected to one side of the outer sealing plate 2113, and a handle 2117 fixedly connected to one side of the outer baffle 2115. A placement box 2111 is fixedly connected to the other side of the outer sealing plate 2113. The interior of the placement box 2111 is provided with a desiccant holding structure 212. An inner sealing plate 2112 is fixedly connected to one side of the placement box 2111. An inner baffle 2114 is fixedly connected to one side of the inner sealing plate 2112. Two guide rods 2116 are fixedly connected between the inner baffle 2114 and the outer baffle 2115. The guide rods 2116 penetrate the cabinet 10 and are slidably connected to the penetration part. The desiccant holding structure 212 includes a desiccant holding box 2121. Ear plates 2122 are fixedly connected to both sides of the interior of the desiccant holding box 2121.

[0045] In this embodiment, when the desiccant inside the desiccant container 2121 needs to be removed and replaced, the outer baffle 2115 is pulled out of the opening by the ear plate 2122. At this time, the inner sealing plate 2112 will seal the opening to prevent moisture from entering the cabinet 10 when replacing the desiccant. Compared with opening the cabinet door 12 for replacement, this method allows the desiccant to be removed and replaced without opening the cabinet door 12, which can reduce the amount of moisture entering the cabinet 10 when replacing the desiccant to a certain extent. By removing the desiccant container 2121 from the cabinet 2111 using the ear plate 2122, the desiccant inside can be poured out, thus allowing for desiccant replacement. After replacement, the cabinet 2111 is pushed back into the cabinet 10 through the opening, and the opening is sealed closed by the outer sealing plate 2113, thus completing the desiccant replacement. The guide rod 2116 can improve the stability of the cabinet 2111 during movement.

[0046] A rain shelter 32 is provided on the top of the cabinet 10. Support columns 31 are fixedly connected to the four corners of the upper end face of the cabinet 10. The upper end face of the support columns 31 is fixedly connected to the lower end face of the rain shelter 32. A mounting plate 41 is fixedly connected to the lower end face of the cabinet 10. Mounting holes are provided at the four corners of the mounting plate 41. A handle is fixedly connected to the front end face of the cabinet door 12. Multiple partitions 13 are fixedly connected inside the cabinet 10. Several through holes are provided on the surface of each partition 13.

[0047] In this embodiment, the rain shield 32 serves to protect against rain. The mounting plate 41 and mounting holes facilitate the placement of the entire device.

[0048] In use, desiccant is placed inside the desiccant container 2121 to absorb moisture inside the cabinet 10. When the desiccant needs to be replaced, the outer baffle 2115 is pulled out through the opening by the ear plate 2122. At this time, the inner sealing plate 2112 seals the opening to prevent moisture from entering the cabinet 10 when replacing the desiccant. Compared with replacing the desiccant by opening the cabinet door 12, this method allows the desiccant to be removed and replaced without opening the cabinet door 12, which can reduce the amount of moisture entering the cabinet 10 when replacing the desiccant. The desiccant container 2121 is removed from the container 2111 by the ear plate 2122, allowing the desiccant to be poured out and replaced. After replacement, the container 2111 is pushed back into the cabinet 10 through the opening, and the outer sealing plate 2113 seals the opening, thus completing the desiccant replacement. The guide rod 2116 can improve the stability of the placement box 2111 when it moves.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
