Description

Technical Field

[0001] This utility model relates to the field of safety tool cabinet technology, specifically a safety tool cabinet with constant dehumidification function. Background Technology

[0002] A safety tool cabinet is a specialized cabinet for storing, storing, and transporting insulated safety tools. Its core function is to prevent insulated tools from getting damp, damaged, or dusty, thereby ensuring that these tools can effectively provide insulation protection during critical moments such as power operations and electrical maintenance, and protecting the lives of operators. Insulated safety tools are usually made of materials such as rubber and epoxy resin, which are most susceptible to moisture. Once they get damp, their insulation performance will drop sharply or even fail. A safety tool cabinet with constant temperature and dehumidification function usually refers to an intelligent constant temperature and dehumidification safety tool cabinet or an intelligent insulated tool cabinet. The existing safety tool cabinet with constant dehumidification function works by introducing outside air into the cabinet through a fan during dehumidification. The air is heated by heating wires under the blow of the fan to reduce humidity, and then the heated and dry air is pushed forward into the cabinet to gradually reduce the overall humidity inside the cabinet. Existing safety tool cabinets with constant dehumidification function have the following problems: when using a safety tool cabinet with constant dehumidification function, the fixed air supply direction causes dry air to not completely cover every area of ​​the cabinet, resulting in poor dehumidification effect. Therefore, we propose a safety tool cabinet with constant dehumidification function. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a safety tool cabinet with constant dehumidification function. When the safety tool cabinet with constant dehumidification function is in use, the left and right swinging air supply direction can make dry air completely cover every area of ​​the cabinet, so as to achieve better dehumidification effect and effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety tool cabinet with constant dehumidification function, including a cabinet body, a uniformly distributed placement plate inside the cabinet body, a protective shell at the rear end of the cabinet body, a heating wire in the middle of the protective shell, and symmetrical fans inside the rear side of the protective shell, and also includes an air guiding mechanism. Air guiding mechanism: It includes a rotating shaft, guide vanes, a protective cover, sprockets and chains. The upper and lower inner walls of the protective shell are rotatably connected by the rotating shaft with evenly distributed guide vanes. Two sprockets are respectively provided at the upper end of the rotating shaft. The two sprockets that are laterally adjacent and located on the same horizontal plane are respectively connected by chain drive. The upper end of the protective shell is provided with a protective cover. The sprockets and chains are located inside the protective cover. When the safety tool cabinet with constant dehumidification function is used, the left and right swinging air supply direction can make the dry air completely cover every area of ​​the cabinet, so as to achieve better dehumidification effect.

[0005] Furthermore, a microcontroller is provided at the left end of the cabinet. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the heating wire and the fan are electrically connected to the output terminal of the microcontroller, providing electrical connections for each electrical appliance.

[0006] Furthermore, the air guiding mechanism also includes a drive assembly, which includes a protective cover, a gear, a rotating column, a quarter-tooth ring, and a quarter-tooth gear. The protective cover is located at the middle of the upper end of the protective cover, and a gear is fixedly connected to the upper end of the central rotating shaft. A rotating column is rotatably connected to the top wall of the protective cover. A quarter-tooth ring is fixedly fitted on the middle of the outer surface of the rotating column, and the quarter-tooth ring is installed in conjunction with the gear. A quarter-tooth gear is fixedly fitted on the lower side of the outer surface of the rotating column, and the quarter-tooth gear is installed in conjunction with the gear to provide a transmission connection.

[0007] Furthermore, the drive assembly also includes a motor, which is located at the upper end of the protective cover. The lower end of the motor's output shaft is fixedly connected to the upper end of the rotating column, and the input end of the motor is electrically connected to the output end of the microcontroller to provide rotation drive.

[0008] Furthermore, the cabinet is equipped with evenly distributed humidity sensors on its left and right inner walls. The input terminals of the humidity sensors are all bidirectionally electrically connected to the microcontroller for easy humidity monitoring.

[0009] Furthermore, a protective mesh is provided on the front side of the interior of the protective shell for protection.

[0010] Furthermore, the front end of the cabinet is hinged with a cabinet door for easy access to tools.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This safety tool cabinet with constant dehumidification function has the following advantages: Driven by a motor, the rotating column rotates. The outer surface of the rotating column is fitted with a quarter-tooth ring and a quarter-tooth gear, which drive the gears to rotate in both forward and reverse directions. This, in turn, drives the sprocket and chain on the central rotating shaft to synchronize the forward and reverse rotation of all rotating shafts. This causes the guide vanes to swing left and right, changing the direction of airflow and allowing dry air to be blown evenly into the interior of the cabinet. This avoids dead zones of localized dryness and dampness, ensuring that the humidity is consistent throughout the cabinet. When using the constant dehumidification function of the safety tool cabinet, the left and right swinging airflow direction ensures that dry air completely covers every area of ​​the cabinet, resulting in better dehumidification.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6This embodiment provides a technical solution: a safety tool cabinet with constant dehumidification function, including a cabinet body 1, with evenly distributed placement plates 2 inside the cabinet body 1, a protective shell 4 at the rear end of the cabinet body 1, a heating wire 6 in the middle of the protective shell 4, and symmetrically arranged fans 7 inside the rear side of the protective shell 4. It also includes an air guiding mechanism 8. A microcontroller 9 is located at the left end of the cabinet body 1, with its input terminal electrically connected to an external power source. The input terminals of the heating wire 6 and the fans 7 are both electrically connected to the output terminal of the microcontroller 9. Humidity sensors 10 are evenly distributed on the left and right inner walls of the cabinet body 1, with their input terminals bidirectionally electrically connected to the microcontroller 9. The protective shell 4... A protective net 5 is installed on the front side of the interior. (The protective shell 4 is bolted to the rear end of the cabinet 1, and the protective net 5 is installed on the front side of the protective shell 4 with studs. The protective net 5 may become clogged after prolonged use, requiring replacement. To replace the protective net 5, first unscrew the bolts, then remove the protective shell 4, then unscrew the studs, remove the protective net 5 for replacement, then reinstall the studs, and finally screw the bolts back on to install the protective shell 4 at the rear end of the cabinet 1.) A cabinet door 3 is hinged to the front end of the cabinet 1. (A door lock is installed between the front end of the cabinet 1 and the rear end of the cabinet door 3. The door lock uses a rotary latch lock, a common type of lock in existing technology.) The rotary latch lock is a mechanical device that achieves locking through a rotating cam structure. Its core consists of a lock cylinder, latch, base, and other components. A sealing ring can be installed between the front edge of cabinet 1 and the rear edge of cabinet door 3 to ensure a leak-proof seal after door 3 is closed. When using the safety tool cabinet, first open cabinet door 3, place the safety tools on the upper part of the placement plate 2, and then close cabinet door 3. The humidity sensors 10 on the left and right inner walls of cabinet 1 will collect humidity data from different areas inside cabinet 1 in real time, avoiding inaccurate detection due to localized humidity dead zones. The humidity sensors 10 transmit the detected data to the microcontroller 9, which integrates the information. When the humidity reaches the preset threshold, the heating wire 6 and the fan 7 operate simultaneously through the control of the microcontroller 9. After the heating wire 6 operates, it heats up quickly and heats the air inside the protective shell to a certain temperature. According to the physical principle, the relative humidity of air with the same water content will decrease after the temperature rises, thus achieving the basic effect of heating and dehumidifying. At the same time, the fan 7 operates and introduces external air into the interior of the protective shell 4 through the air vent at the rear of the protective shell 4. After the air enters the protective shell 4, it is heated and dehumidified by the heating wire 6 under the blowing of the fan 7. The heated and dry air is then pushed forward and sent into the cabinet 1 through the protective net 5 on the front side of the protective shell 4, gradually reducing the overall humidity inside the cabinet. The air guiding mechanism 8 includes a rotating shaft 81, guide vanes 82, a protective cover 83, sprockets 84, and a chain 85. The upper and lower inner walls of the protective shell 4 are rotatably connected by the rotating shaft 81, with evenly distributed guide vanes 82. Two sprockets 84 are respectively provided at the upper end of the rotating shaft 81. The two sprockets 84, which are laterally adjacent and located on the same horizontal plane, are respectively connected by a chain 85. A protective cover 83 is provided at the upper end of the protective shell 4. Both the sprockets 84 and the chain 85 are located inside the protective cover 83. The air guiding mechanism 8 also includes a drive assembly 86, which includes a protective cover 861, gears 862, a rotating column 863, a quarter-tooth ring 864, and a quarter-tooth gear 865. A protective cover is provided in the middle of the upper end of the protective cover 83. The protective cover 861 has a gear 862 fixedly connected to the upper end of the central rotating shaft 81. A rotating column 863 is rotatably connected to the top wall of the protective cover 83. A quarter-tooth ring 864 is fixedly fitted onto the middle of the outer surface of the rotating column 863, and the quarter-tooth ring 864 mates with the gear 862. A quarter-tooth gear 865 is fixedly fitted onto the lower side of the outer surface of the rotating column 863, and the quarter-tooth gear 865 mates with the gear 862. The drive assembly 86 also includes a motor 866, which is located at the upper end of the protective cover 861. The lower end of the output shaft of the motor 866 is fixedly connected to the upper end of the rotating column 863. The input end of the motor 866 is electrically connected to the output end of the microcontroller 9. The motor 866 will then be controlled by the microcontroller 9. When motor 866 operates, its output shaft drives the lower rotating column 863 to rotate. A quarter-tooth ring 864 and a quarter-tooth gear 865, fitted on the outer surface of the rotating column 863, rotate accordingly. (The quarter-tooth ring 864 and quarter-tooth gear 865 are staggered vertically and do not mesh with gear 862 simultaneously.) When the rotating column 863 rotates to the point where the quarter-tooth ring 864 meshes with gear 862 on the central rotating shaft 81, the quarter-tooth ring 864 drives gear 862 to rotate in the forward direction. When the rotating column 863 continues to rotate until the quarter-tooth gear 865 meshes with gear 862, gear 865 drives gear 862 to rotate in the reverse direction. This process, through the alternation of the quarter-tooth ring 864 and quarter-tooth gear 865, continues. The unidirectional rotation of the motor 866 is converted into alternating forward and reverse rotation of the central rotating shaft 81. The upper end of the central rotating shaft 81 is equipped with a sprocket 84. The lateral adjacent sprockets 84 are driven by a chain 85. When the central rotating shaft 81 rotates forward and reverse, it will drive all the rotating shafts 81 inside the protective shell 4 to rotate forward and reverse synchronously through the transmission of the sprockets 84 and the chain 85. Each rotating shaft 81 is fixed with a guide vane 82. When the rotating shaft 81 rotates forward and reverse, the guide vane 82 will swing left and right. The swinging guide vane 82 can change the direction of the air blown forward by the protective shell 4, so that the dry air is blown evenly to the left and right sides of the cabinet and the upper and lower placement plates 2, avoiding dead corners of local dryness and local dampness, and ensuring that the humidity of all areas inside the cabinet 1 is consistent.

[0016] The working principle of the safety tool cabinet with constant dehumidification function provided by this utility model is as follows: When using the safety tool cabinet, first open the cabinet door 3, place the safety tools on the upper part of the placement plate 2, and then close the cabinet door 3. The humidity sensors 10 on the left and right inner walls of the cabinet body 1 will collect humidity data of different areas inside the cabinet body 1 in real time, avoiding inaccurate detection due to local humidity dead zones. The humidity sensors 10 transmit the detected data to the microcontroller 9. The microcontroller 9 integrates the information. When the detected humidity reaches the preset threshold, the heating wire 6 and the fan 7 operate simultaneously through the control of the microcontroller 9. After the heating wire 6 operates, it heats up quickly, heating the air inside the protective shell. Upon reaching a certain temperature, according to physical principles, air with the same moisture content will experience a decrease in relative humidity as the temperature rises, achieving the basic effect of heating and dehumidifying. Simultaneously, fan 7 operates, drawing external air into the interior of the protective shell 4 through the vent at the rear. Once inside, the air is heated and dehumidified by the heating wire 6 under the influence of fan 7. The heated, dry air is then pushed forward, passing through the protective mesh 5 on the front of the protective shell 4 and into the cabinet 1, gradually reducing the overall humidity inside the cabinet. Next, the microcontroller 9 controls the operation of motor 866, whose output shaft drives the lower rotating column 863 to rotate. The outer surface of the rotating column 863 is fitted with... Quarter-gear ring 864 and quarter-gear 865 rotate accordingly (the quarter-gear ring 864 and quarter-gear 865 are staggered vertically and do not mesh with gear 862 simultaneously). When the rotating column 863 rotates to the point where the quarter-gear ring 864 meshes with gear 862 on the central rotating shaft 81, the quarter-gear ring 864 drives gear 862 to rotate in the forward direction. When the rotating column 863 continues to rotate to the point where the quarter-gear 865 meshes with gear 862, gear 865 drives gear 862 to rotate in the reverse direction. Through the alternating meshing of the quarter-gear ring 864 and quarter-gear 865, the unidirectional rotation of motor 866 is converted into central rotation. The central rotating shaft 81 rotates in both forward and reverse directions. A sprocket 84 is provided at the upper end of the central rotating shaft 81. The lateral adjacent sprockets 84 are driven by a chain 85. When the central rotating shaft 81 rotates in both directions, it will drive all the rotating shafts 81 inside the protective shell 4 to rotate in both directions synchronously through the transmission of the sprockets 84 and the chain 85. Each rotating shaft 81 is fixed with a guide vane 82. When the rotating shaft 81 rotates in both directions, the guide vane 82 will swing left and right. The swinging guide vane 82 can change the direction of the air blown forward by the protective shell 4, so that the dry air is blown evenly to the left and right sides of the cabinet and the upper and lower placement plates 2, avoiding dead corners of local dryness and local dampness, and ensuring that the humidity of all areas inside the cabinet 1 is consistent.

[0017] It is worth noting that, in the above embodiments, the heating wire 6, fan 7, motor 866, and humidity sensor 10 can all be selected as follows: heating wire 6 can be Ocr21al6nb; fan 7 can be W2E250-HJ28-01; motor 866 can be 35BYJ46; and humidity sensor 10 can be selected as follows. The PG-310 microcontroller 9 controls the heating wire 6, fan 7, motor 866, and humidity sensor 10 using methods commonly used in existing technologies.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
