Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning control cabinets, and in particular to an air conditioning control cabinet for cleanrooms. Background Technology

[0002] An air conditioning control cabinet is the core equipment used to control the operation of an air conditioning system. It contains various control components, such as contactors, relays, circuit breakers, and PLCs (programmable logic controllers). Its main functions include: controlling the on / off state of the air conditioner, adjusting the temperature and fan speed, monitoring the system status, and protecting the circuit.

[0003] Referring to patent CN221531829U, an air conditioning energy-saving control cabinet is disclosed, including a cabinet body. Mounting grooves are provided on both outer walls of the cabinet body, communicating with the interior of the cabinet. Filter plates are installed in both mounting grooves. Cleaning devices for cleaning the filter plates are installed on both outer walls of the cabinet body. Mounting plates are fixedly connected to both outer walls of the cabinet body. A reciprocating screw is connected to a scraper via a connecting mechanism. The scraper is slidably connected to the outer wall of the filter plate. Limiting rods are fixedly connected between two sets of fixed plates, and the limiting rods are connected to the scraper via a limiting mechanism. This utility model, by setting up scrapers, reciprocating screws, and other devices, utilizes the rotation of the reciprocating screw to drive the screw sleeve to move the scraper back and forth on the outer wall of the filter plate. During the sliding process, dust on the outer wall of the filter plate can be scraped off, preventing clogging of the filter plate and ensuring the heat dissipation effect of the internal components of the cabinet.

[0004] Because the air conditioning control cabinet is located inside the cleanroom, the emergency stop button or power switch on the control cabinet is exposed, which may cause personnel or materials to accidentally bump into or touch it, resulting in accidental impact or accidental activation, causing the air conditioning system to suddenly stop, and causing the temperature and pressure difference in the cleanroom to instantly become uncontrollable. Utility Model Content

[0005] In view of the problem that existing air conditioning control cabinets used in cleanrooms have exposed emergency stop buttons or power switches, which may lead to accidental collisions or contact with personnel or materials, resulting in sudden shutdown of the air conditioning system, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an air conditioning control cabinet for a cleanroom, comprising a control cabinet body and a mounting frame, wherein a support frame is fixedly installed on the top of the control cabinet body, a protective plate is rotatably connected to the front end of the top of the support frame, and the size of the protective plate is consistent with the front end size of the control cabinet body, a fixing component is provided on the right end of the control cabinet body, and a heat dissipation component is provided on the control cabinet body box, and a lifting component is provided on the frame of the mounting frame, and the mounting frame is configured in a "U" shaped structure.

[0007] In this example, the fixing component includes a pull rod. The pull rod is fixedly installed on the right end of the protective plate shaft, and a positioning hole is provided on the rod body. A fixing ear is fixedly installed on the upper right end of the control cabinet body, and a limit plug is slidably connected to the frame of the fixing ear. The front end of the limit plug is set to correspond to the positioning hole, and a spring is sleeved on the outer side of the limit plug.

[0008] In this example, the heat dissipation component has ventilation slots, ventilation slots are provided at both the left and right ends of the control cabinet body, and a cooling fan is fixedly installed at the middle position of the top of the control cabinet body.

[0009] In this example, the support frame is set in an "L" shaped structure, and connecting blocks are fixedly installed at both the left and right ends of the rear end of the support frame.

[0010] In this example, the lifting assembly includes a slide rod, the right end of the mounting bracket is fixedly mounted with the slide rod, and the left end of the mounting bracket is rotatably connected with a threaded rod.

[0011] In this example, the slide bar is slidably connected to the right connecting block in the support frame, and the threaded rod is connected to the left connecting block in the support frame.

[0012] In this example, a first gear is fixedly installed at the upper end of the threaded rod, and a second gear is rotatably connected to the left end of the top of the mounting bracket, with the second gear meshing with the first gear. A motor is fixedly installed at the top of the mounting bracket, and the output end of the motor is connected to the shaft of the second gear.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model uses a protective plate whose dimensions are consistent with the front end dimensions of the control cabinet body. By gripping the pull rod on the right end shaft of the protective plate, the protective plate rotates on the support frame, thus covering the front end of the control cabinet body. Then, pulling the limiting rod on the fixed ear frame causes the limiting rod to compress the spring, so that the rod body of the limiting rod corresponds to the positioning hole on the pull rod. The spring force drives the limiting rod to reset, so that the rod body of the limiting rod is inserted into the diameter of the positioning hole. The protective plate is fixed by the pull rod. The flipping of the protective plate can prevent personnel or objects from accidentally touching the emergency stop button or power switch, thus avoiding production interruption caused by the sudden shutdown of the air conditioning system.

[0014] 2. This utility model has ventilation slots on both the left and right ends of the control cabinet body, and a cooling fan is fixedly installed on the top of the control cabinet body. The operation of the cooling fan can dissipate heat from the internal components of the control cabinet body. The cooperation between the cooling fan and the ventilation slots can allow air circulation inside the control cabinet body. The cooperation between the ventilation slots and the cooling fan can transfer heat to the outside and keep the electronic components within the optimal operating range.

[0015] 3. This utility model connects the output end of the motor to the shaft of the second gear, and the second gear meshes with the first gear on the threaded rod. The motor's operation drives the threaded rod to rotate. The threaded rod is connected to the left connecting block of the support frame via a thread, and simultaneously slidably connected to the right connecting block of the support frame via a sliding rod. The rotation of the threaded rod raises and lowers the control cabinet body, allowing for height adjustment. This adjustment prevents accidents caused by improper posture during maintenance or operation, and also facilitates observation and operation, thus improving overall safety and reliability.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-5This is the first embodiment of the present invention, which provides an air conditioning control cabinet for a cleanroom. The air conditioning control cabinet for a cleanroom includes a control cabinet body 1 and a mounting frame 12. A support frame 2 is fixedly installed on the top of the control cabinet body 1. A protective plate 3 is rotatably connected to the front end of the top of the support frame 2. The size of the protective plate 3 is the same as the front end size of the control cabinet body 1. When closed, it can completely cover key areas such as the operation panel, buttons, and interfaces, forming a rigid physical barrier. A fixing component is provided on the right end of the control cabinet body 1, and a heat dissipation component is provided on the cabinet body 1. A lifting component is provided on the frame of the mounting frame 12, and the mounting frame 12 is set in a "U" shaped structure.

[0020] In this example, the fixing component includes a pull rod 4. The pull rod 4 is fixedly installed on the right end of the shaft of the protective plate 3, providing a clear force point for rotating the protective plate. The pull rod 4 has a positioning hole 5. The upper right end of the control cabinet body 1 is fixedly installed with a fixing ear 6, which provides stable sliding support for the limit plug rod. The limit plug rod 7 is slidably connected to the frame of the fixing ear 6. The front end of the limit plug rod 7 is set in a corresponding state with the positioning hole 5, which can completely lock the closed position of the protective plate to prevent it from loosening or shifting. A spring 8 is sleeved on the outside of the limit plug rod 7.

[0021] In this example, the heat dissipation component maintains the ventilation slot 10, and ventilation slots 10 are provided at both the left and right ends of the control cabinet body 1. A cooling fan 11 is fixedly installed at the middle position of the top of the control cabinet body 1, which can flexibly adapt to the dynamically changing heat load inside the cabinet.

[0022] In this example, the support frame 2 is set in an "L" shaped structure to avoid excessive force on a single point, which could lead to deformation or breakage. Furthermore, connecting blocks 9 are fixedly installed on both the left and right ends of the rear end of the support frame 2.

[0023] In this example, the lifting assembly includes a slide rod 13. The slide rod 13 is fixedly installed on the right end of the mounting bracket 12, and a threaded rod 14 is rotatably connected to the left end of the mounting bracket 12. The slide rod is a guide structure, and the threaded rod is a drive structure. The two are arranged in parallel to form a symmetrical support.

[0024] In this example, the slide bar 13 is slidably connected to the right connecting block 9 in the support frame 2 to form a precise longitudinal guide trajectory. The threaded rod 14 is connected to the left connecting block 9 in the support frame 2. The connecting blocks on the left and right sides restrict the degree of freedom of the cabinet from the drive end and the guide end, respectively.

[0025] In this example, a first gear 15 is fixedly installed on the upper end of the threaded rod 14, and a second gear 16 is rotatably connected to the left end of the top of the mounting bracket 12. The second gear 16 meshes with the first gear 15. A motor 17 is fixedly installed on the top of the mounting bracket 12, and the output end of the motor 17 is connected to the shaft of the second gear 16. The first gear and the second gear mesh precisely through their tooth profiles, and there is no relative slippage during transmission, which can transmit the torque of the motor to the threaded rod.

[0026] During use, because the mounting bracket 12 is a "U"-shaped structure, a sliding rod 13 is fixedly installed on the right end of the mounting bracket 12, and a threaded rod 14 is rotatably connected to the left end of the mounting bracket 12. A support bracket 2, which is an "L"-shaped structure, is fixedly installed on the top of the control cabinet body 1, and connecting blocks 9 are fixedly installed on both the left and right ends of the rear end of the support bracket 2. The sliding rod 13 is slidably connected to the right connecting block 9 in the support bracket 2, and the threaded rod 14 is threadedly connected to the left connecting block 9 in the support bracket 2. Thus, the control cabinet body 1 is mounted on the wall via the mounting bracket 12. After the control cabinet body 1 is installed in the designated position, a first gear 15 is fixedly installed on the upper end of the threaded rod 14, and a second gear 15 is rotatably connected to the left end of the top of the mounting bracket 12. 6. A motor 17 is fixedly installed on the top of the support frame 2, and the output end of the motor 17 is connected to the shaft of the second gear 16. The motor 17 can be controlled by the controller. When the motor 17 is running, it can drive the threaded rod 14 to rotate on the frame of the mounting frame 12 through the meshing between the first gear 15 and the second gear 16. This drives the control cabinet body 1 to rise and fall through the left connecting block 9 in the support frame 2, and slides on the rod of the slide rod 13 through the right connecting block 9 in the support frame 2, thereby adjusting the height of the control cabinet body 1. At the same time, the height of the control cabinet body 1 can also be adjusted by controlling the motor 17 during daily maintenance and use. Adjusting the control cabinet body 1 can avoid safety accidents caused by improper posture of the operator during maintenance or operation, and also facilitates the operator's observation and operation. After the control cabinet body 1 is installed in the designated position, a protective plate 3 is rotatably connected to the front end of the top of the support frame 2, and a pull rod 4 is fixedly installed on the shaft of the right end of the protective plate 3. A positioning hole 5 is opened on the rod of the pull rod 4. At the same time, a fixing ear 6 is fixedly installed on the upper end of the right end of the control cabinet body 1, and a limit plug 7 is slidably connected to the frame of the fixing ear 6. A spring 8 is sleeved on the outer side of the limit plug 7, so that the limit plug 7 can be pulled and the spring 8 can be compressed. Then, the pull rod 4 is grasped and the protective plate 3 is flipped over, because the protective plate 3... The size is consistent with the size of the front door of the control cabinet body 1, so that the protective plate 3 covers the front of the control cabinet body 1. Since the positioning hole 5 and the limit rod 7 are set in a corresponding state, the pull on the limit rod 7 is released, and then the spring force of the spring 8 drives the limit rod 7 to reset, so that the limit rod 7 is ejected into the aperture of the positioning hole 5, thereby fixing the position of the protective plate 3. By flipping the protective plate 3, the accidental contact of personnel or objects with the emergency stop button or power switch can be avoided, thereby avoiding production interruption caused by the sudden shutdown of the air conditioning system. When the control cabinet body 1 is in operation, ventilation slots 10 are provided on both the left and right ends of the control cabinet body 1, and a cooling fan 11 is fixedly installed on the top of the control cabinet body 1. The cooling fan 11 can be controlled by the controller. When the cooling fan 11 is in operation, it can dissipate heat from the components inside the control cabinet body 1. At the same time, the ventilation slots 10 can exhaust the heat generated inside the control cabinet body 1. The cooperation between the ventilation slots 10 and the cooling fan 11 can make the air inside the control cabinet body 1 circulate. The cooperation between the ventilation slots 10 and the cooling fan 11 can transfer heat to the outside and keep the electronic components within the optimal operating range.
