Description

Technical Field

[0001] This utility model relates to the technical field of intelligent dehumidification devices, specifically a plastic-shell type intelligent dehumidification device. Background Technology

[0002] Condensation can easily occur inside switchgear and other equipment, leading to creepage and flashover accidents. In such cases, to ensure the safe operation of the power grid system, intelligent dehumidification devices are needed to extend the lifespan of electrical equipment and ensure its safe and efficient use. Typically, intelligent dehumidification devices are required. These devices utilize semiconductor refrigeration to actively draw humid air from a sealed space into a dehumidification duct using a fan. The water vapor in the air condenses into water after passing through the semiconductor refrigeration mechanism and is then discharged from the cabinet through a drain pipe, achieving excellent dehumidification. Intelligent dehumidification devices are small, lightweight, and suspended in their enclosures. In existing technologies, power supply boxes are often fixed to walls or other load-bearing surfaces using expansion bolts, making disassembly, maintenance, and repositioning inconvenient and difficult.

[0003] Based on this, a search on the patent website revealed a dual-row digital display intelligent dehumidifier disclosed in Chinese patent announcement number CN211316639U.

[0004] It can be seen that the above-mentioned patent has the following shortcomings: the traditional power box structure is relatively simple.

[0018] 1. This utility model discloses a plastic-shell type intelligent dehumidifier. The practical intelligent dehumidifier adopts the YJ-ZCS-AS model, which is a small and lightweight dehumidifier. It is a mature existing technology in the market and is widely produced. The YJ-ZCS series intelligent dehumidifier consists of a power system, an air supply system, a semiconductor cooler, a temperature and humidity detection and control circuit, a heating circuit, and a drainage pipe. Its dehumidification principle is that when humid air is drawn in by the fan, it flows through a specially designed air duct, first passing through the semiconductor cooler to cool and condense. The condensate from the cooler drips into the water tank under gravity and then flows out of the cabinet through the water pipe. After sufficient circulation and dehumidification within the set start value, the humidity of the air inside the cabinet is reduced to below the dew point, completing the entire moisture-proof condensation heating process. At the same time, the intelligent dehumidifier has an external signal acquisition sensor, which can accurately collect the real humidity inside the cabinet in real time, ensuring that the intelligent dehumidifier starts dehumidification in advance when the condensation conditions inside the cabinet are about to be reached.

[0019] 2. Install a filter screen on one side of the air inlet. The filter screen can effectively block external dust and impurities from entering the dehumidification box assembly, preventing dust and impurities from affecting the normal operation of the dehumidification box assembly. At the same time, the filter screen is set on the outside of the dehumidification box assembly, which is convenient for users to clean and maintain.

[0020] 3. During the installation of the plastic-shell type intelligent dehumidifier, this utility model adds an installation positioning component to solve this problem. The operator first fixes the frame plate stably on the wall. When it is necessary to suspend the dehumidifier box component on one side of the wall, the installation column is placed between the two sets of positioning arc plates. Turning the knob drives the first rotating roller to rotate. Due to the transmission of the first rotating roller, the two sets of moving blocks move closer to each other, and then the two sets of positioning arc plates move closer to each other until the installation column is clamped and fixed. The two sets of positioning arc plates wrap around the outer perimeter of the installation column. At the same time, the first magnet and the second magnet are magnetically fixed, further improving the installation stability between the positioning arc plates and the installation column.

[0021] 4. If subsequent maintenance of the dehumidifier housing assembly is required, rotate the knob in the opposite direction to cause the second roller and the forward and reverse threaded rods to rotate in opposite directions. The two sets of moving blocks will move away from each other, and the two sets of positioning arc plates will move in opposite directions. At this time, both sets of positioning arc plates will be completely away from the mounting column. Then, pull the dehumidifier housing assembly away from the mounting positioning assembly to detach it from the mounting positioning assembly. The operation is simple and convenient. This setting facilitates the user's wall-mounting and fixing of the dehumidifier housing assembly to the wall through the mounting positioning assembly, and avoids damage to the wall during wall mounting and disassembly. The simple installation and disassembly operation facilitates the maintenance of the dehumidifier housing assembly and improves the practicality of the device.

A mounting cavity 22 is provided on one side of the frame plate 21. The mounting cavity 22 is connected to the frame plate 21. A driving component is provided on one side of the mounting cavity 22. The driving component is used to drive the positive and negative threaded rod 25 to rotate, thereby achieving the effect of adjusting the distance between the two sets of positioning arc plates 24.

[0034] The present invention will be further described below with reference to the embodiments. Example 1

[0035] Please see Figure 1-5A plastic-shell type intelligent dehumidifier includes a set of positioning arc plates 24 with a movable block 26 threadedly connected to the outer periphery of a positive and negative threaded rod 25 on one side, and a movable block 26 on the other side of the same set of positioning arc plates 24 slidably connected to the outer periphery of a limiting rod 23. The drive assembly includes a first drive assembly 3, which includes a knob 31 rotatably connected to the outside of a mounting cavity 22.

[0036] Working Principle: This practical intelligent dehumidifier uses the YJ-ZCS-AS model, a small and lightweight dehumidifier. It represents a mature technology already widely available and in production. The YJ-ZCS series intelligent dehumidifier consists of a power system, an air supply system, a semiconductor cooler, a temperature and humidity detection and control circuit, a heating circuit, and a drainage pipe. Its dehumidification principle is as follows: humid air is drawn in by the fan and flows through a specially designed air duct. It is first cooled and condensed by the semiconductor cooler. The condensate drips into the water tank under gravity and then flows out of the cabinet through the water pipe. Within the set start-up value, sufficient circulation and dehumidification are performed, reducing the humidity inside the cabinet below the dew point, completing the entire moisture-proof condensation heating process. Simultaneously, the intelligent dehumidifier has an external signal acquisition sensor, which can accurately collect the actual humidity inside the cabinet in real time, ensuring that the intelligent dehumidifier starts dehumidification in advance when condensation conditions are about to occur inside the cabinet.

[0037] A filter screen 15 is installed on one side of the air inlet 13. The filter screen 15 can effectively block external dust and impurities from entering the dehumidification box assembly 1, preventing dust and impurities from affecting the normal operation of the dehumidification box assembly 1. At the same time, the filter screen 15 is set on the outside of the dehumidification box assembly 1, which is convenient for users to clean and maintain.

[0038] In most cases, the dehumidifier housing assemblies 1 are directly fixed to the wall during installation. When maintenance or disassembly is required, the entire housing assemblies 1 must be removed, a cumbersome process that can damage the wall. Therefore, this invention includes a mounting and positioning assembly 2 to address this issue. The operator pre-fixes the frame plate 21 to the wall. When the dehumidifier housing assemblies 1 need to be suspended on one side of the wall, the mounting post 11 is placed between two sets of positioning arc plates 24. Rotating the knob 31 causes the first roller 32 to rotate. Due to the transmission of the first roller 32, the knob 31 drives the second roller 34 and the positive and negative threaded rods 25 to rotate. This causes the two sets of moving blocks 26 to move closer together, and consequently, the two sets of positioning arc plates 24 to move closer together until the mounting post 11 is clamped and fixed. The two sets of positioning arc plates 24 wrap around the outer perimeter of the mounting post 11. The first magnet and the second magnet are magnetically fixed together, further improving the installation stability between the positioning arc plate 24 and the mounting column 11. If the dehumidification box assembly 1 needs to be repaired later, the knob 31 is rotated in the opposite direction, causing the second roller 34 and the positive and negative threaded rods 25 to rotate in the opposite direction. The two sets of moving blocks 26 move away from each other, and the two sets of positioning arc plates 24 move in opposite directions. At this time, both sets of positioning arc plates 24 are completely away from the mounting column 11. Then, the dehumidification box assembly 1 can be pulled away from the mounting positioning assembly 2 to remove the dehumidification box assembly 1 from the mounting positioning assembly 2. The operation is simple and convenient. This setting makes it convenient for users to wall-mount and fix the dehumidification box assembly 1 to the wall through the mounting positioning assembly 2, and avoids damage to the wall during wall mounting and disassembly. Moreover, the simple installation and disassembly operation realizes the function of facilitating the maintenance of the dehumidification box assembly 1 and improving the practicality of the device. Example 2

[0039] Please see Figure 6 Example 2 of this utility model adopts a second driving component. The difference between this embodiment and Example 1 is that the driving component includes a second driving component 4, and the second driving component 4 includes a rotating disk 41 rotatably connected to the outside of the mounting cavity 22, and a rotating rod 42 rotatably connected to the inner cavity of the mounting cavity 22, and the rotating rod 42 is fixedly connected to the rotating disk 41. One end of the rotating rod 42 is fixedly connected to a first bevel gear 43, and the first bevel gear 43 is rotatably connected to the inner cavity of the mounting cavity 22. One end of the positive and negative threaded rod 25 is fixedly connected to a second bevel gear 44, and the second bevel gear 44 meshes with the first bevel gear 43.

[0040] Working principle: The mounting post 11 is placed between two sets of positioning arc plates 24. Rotating the rotating disk 41 causes the rotating rod 42 to rotate. Due to the transmission of the rotating rod 42, the rotating rod 42 drives the first bevel gear 43 and the second bevel gear 44 to rotate, which in turn rotates the forward and reverse threaded rod 25. At this time, the two sets of moving blocks 26 move closer to each other, and the two sets of positioning arc plates 24 move closer to each other until the mounting post 11 is clamped and fixed. The two sets of positioning arc plates 24 wrap around the outer periphery of the mounting post 11. Simultaneously, the first magnet and the second magnet are magnetically fixed together, further enhancing the grip. The installation stability between the positioning arc plate 24 and the mounting column 11 is improved. If the dehumidification box assembly 1 needs to be repaired later, the rotating disk 41 is rotated in the opposite direction, causing the rotating rod 42 to rotate in the opposite direction, and then the positive and negative threaded rods 25 rotate in the opposite direction. The two sets of moving blocks 26 move away from each other, and then the two sets of positioning arc plates 24 move in opposite directions. At this time, both sets of positioning arc plates 24 are completely away from the mounting column 11. Then, the dehumidification box assembly 1 can be pulled away from the mounting positioning assembly 2 to remove the dehumidification box assembly 1 from the mounting positioning assembly 2. The operation is simple and convenient. Example 3

[0041] Please see Figure 7 Example 3 of the present utility model adopts a third drive component. The difference between this embodiment and Example 1 is that the drive component includes a third drive component 5, which is a micro motor. The third drive component 5 is fixedly installed on one side of the inner wall of the frame plate 21, and the positive and negative threaded rods 25 are connected to the output end of the third drive component 5.

[0042] Working principle: The mounting post 11 is placed between two sets of positioning arc plates 24. The working mode of the third drive component 5 is activated, causing the output end of the third drive component 5 to rotate in the forward direction. Consequently, the forward and reverse threaded rods 25 rotate in the forward direction. At this time, the two sets of moving blocks 26 move closer to each other, and the two sets of positioning arc plates 24 move closer to each other until the mounting post 11 is clamped and fixed. The two sets of positioning arc plates 24 wrap around the outer periphery of the mounting post 11. At the same time, the first magnet and the second magnet are magnetically fixed, further enhancing the connection between the positioning arc plates 24 and the mounting post 11. The installation ensures stable performance. If subsequent maintenance of the dehumidification box assembly 1 is required, the output end of the third drive assembly 5 is rotated in the opposite direction, which in turn causes the positive and negative threaded rods 25 to rotate in the opposite direction. The two sets of moving blocks 26 move away from each other, and the two sets of positioning arc plates 24 move in opposite directions. At this time, both sets of positioning arc plates 24 are completely away from the mounting column 11. Then, the dehumidification box assembly 1 can be pulled away from the mounting positioning assembly 2 to remove the dehumidification box assembly 1 from the mounting positioning assembly 2. The operation is simple, convenient, and automated, improving the efficiency of the device.
