Description

Technical Field

[0001] This invention relates to the field of electrical cabinet internal cleaning technology, specifically to an intelligent cleaning electrical cabinet for a gantry machine tool. Background Technology

[0002] The electrical components inside the electrical cabinet of a gantry milling machine, including servo drives and I / O modules, require a relatively dust-free working environment. Excessive dust entering the cabinet can affect the operation of these electronic devices, leading to damage and scrapping of the workpiece. While manual cleaning is typically used, it lacks timeliness.

[0003] When using automatic cleaning inside electrical cabinets, for example, in the patent document with application number 202311534361.X, a self-cleaning electrical control box is disclosed, which specifically discloses that the dust inside the electrical cabinet is removed by shaking it off and blowing it to the position of the retractable airbag by an exhaust fan.

[0004] In the above technical solution, when the dust is shaken off by vibration, the dust accumulated at the vent will fall into the electrical cabinet. When the dust is blown to the shrink air bag by the exhaust fan for collection, a lot of dust falls into the electrical cabinet. Under the electrostatic adsorption of the electrical components, it is very easy to stick to the electrical components. Slight vibration cannot shake off the dust, which affects the cleaning effect inside the electrical cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent cleaning electrical cabinet for a gantry milling machine.

[0006] The technical problem solved by this invention is to address the issue in the prior art where dust adhering to the vents is dispersed onto the electrical components of the electrical cabinet when cleaned by wind, making the electrical components difficult to clean.

[0007] The present invention can be achieved through the following technical solution: an intelligent cleaning electrical cabinet for a gantry milling machine, comprising an electrical cabinet, a ventilation opening provided on the electrical cabinet, and a dust sensor for dust detection provided inside the electrical cabinet, and an internal dust removal plate and an external dust removal plate slidably disposed on the electrical cabinet for cleaning the ventilation opening, the internal dust removal plate being provided with a dust removal mechanism, and the sliding speed of the internal dust removal plate being greater than the sliding speed of the external dust removal plate.

[0008] A further technical improvement of the present invention is that the internal dust removal plate is a flat plate, and the external dust removal plate is provided with a mesh opening for dust to be sprayed out.

[0009] A further technical improvement of the present invention is that: a hoisting end is fixed on the external dust removal plate and the internal dust removal plate respectively, and the hoisting end is installed at the output end of the hoisting equipment.

[0010] A further technical improvement of the present invention is that the hoisting equipment includes a bidirectional motor, and the two output ends of the bidirectional motor are respectively provided with drive shafts. A winding roller is fixed on the drive shaft, and a hoisting steel wire is wound on the winding roller. The other end of the hoisting steel wire is installed on the hoisting end.

[0011] A further technical improvement of the present invention is that the internal dust removal plate and the external dust removal plate are respectively installed on the electrical cabinet through a sliding limit mechanism.

[0012] A further technical improvement of the present invention is that: the sliding limit mechanism includes a rotating gear, the rotating gear is mounted on a damping shaft, the damping shaft is rotatably connected to the electrical cabinet, and a fixed rack is fixed on the side of the electrical cabinet, the fixed rack meshing with the rotating gear.

[0013] A further technical improvement of the present invention is that the dust removal mechanism includes a nozzle array, which is uniformly and fixedly installed inside the internal dust removal plate, and the nozzle array is connected to the output end of the micro air pump through a connecting air pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This application employs the combined action of an external dust removal plate and an internal dust removal plate. When cleaning dust inside the electrical cabinet is required, the internal and external dust removal plates are first slid together. The internal dust removal plate first lands at the vent, and then the dust removal mechanism is activated to initially remove dust from the vent. During this process, the external dust removal plate gradually slides on the electrical cabinet, generating vibration to remove impurities from the vent. This effectively cleans the vent, preventing dust from entering the interior of the electrical cabinet and solving the problem of dust adhering to the vent and escaping into the electrical cabinet, making it difficult to clean electrical components.

[0016] 2. This application employs a rotating gear mounted on a damping shaft, which is rotatably connected to the electrical cabinet. A fixed rack is also fixed on the side of the electrical cabinet, where the fixed rack meshes with the rotating gear. This causes the internal and external dust removal plates to fall naturally under gravity. The interaction between the fixed and rotating gears easily generates vibration, facilitating the cleaning of the ventilation openings under vibration and preventing dust from entering the interior of the electrical cabinet.

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0031] Please see Figure 1-11 As shown, an intelligent cleaning electrical cabinet for a gantry milling machine includes an electrical cabinet 12. Inside the electrical cabinet 12 is a dust sensor 1 for monitoring the dust concentration inside the cabinet. At the top of the electrical cabinet 12 is a dust concentration display screen 3 for displaying the data obtained from the dust sensor 1. Inside the electrical cabinet 12 is a unidirectional exhaust fan 5 for realizing gas flow. Inside the electrical cabinet 12 are a red running light 9 and a green standby light 11 for displaying the internal status of the electrical cabinet 12. Inside the electrical cabinet 12 is a microcontroller 2 for performing algorithm calculations and control. Simultaneously, inside the electrical cabinet 12 is a control module 13 for controlling the unidirectional exhaust fan 5. The control module 13 includes relay module one 4, relay module two 6, relay module three 8, and relay module four 10.

[0032] In use, dust sensor 1 first detects the dust concentration inside electrical cabinet 12 and transmits the dust concentration value to microcontroller 2. Microcontroller 2 displays the dust concentration value on dust concentration display screen 3 and monitors the dust concentration value. When the dust concentration value is higher than the preset value, microcontroller 2 activates relay module 4 to control the unidirectional exhaust fan 5 for exhaust. Then, microcontroller 2 controls relay module 6 to activate the purification function of electronic purification device 7. Microcontroller 2 activates relay module 8 to activate the red running light 9. When the dust concentration value is lower than the preset value, microcontroller 2 activates relay module 10 to activate the green standby light 11.

[0033] An air vent 14 for gas circulation is provided on the electrical cabinet 12. An external dust removal plate 15 and an internal dust removal plate 17 are slidably provided on the air vent 14 to clean the dust on the air vent 14 separately before cleaning the electrical cabinet 12. Then, the cleaned air vent 14 is opened by the sliding limit mechanism 16 to start the internal dust removal device of the electrical cabinet 12.

[0034] Specifically, the internal dust removal plate 17 in this application can be slid to the position of the vent 14 through the sliding limiting mechanism 16 to block the vent 14. The dust removal mechanism inside the internal dust removal plate 17 can then remove the dust from the vent 14. By using the blocking effect of the internal dust removal plate 17, dust is prevented from falling into the electrical cabinet 12, thereby reducing the possibility of dust from the vent 14 adhering to the electrical components.

[0035] In this application, the external dust removal plate 15 can be slid to the position of the vent 14 via the sliding limit mechanism 16. Then, the mesh opening on the external dust removal plate 15, in conjunction with the dust removal mechanism, allows the dust adhering to the vent 14 to be removed from the mesh opening with strong airflow, thereby cleaning the vent 14 and preventing dust from falling directly into the interior of the electrical cabinet 12.

[0036] Specifically, the external dust removal plate 15 and the internal dust removal plate 17 are respectively installed on the electrical cabinet 12 through a sliding limiting mechanism 16. Therefore, the sliding limiting mechanism 16 includes a first fixed support plate 161 for initially limiting the internal dust removal plate 17, and a second fixed support plate 162 for longitudinally limiting the internal dust removal plate 17. A hoisting end 163 for hoisting equipment installation is fixed on the internal dust removal plate 17. In use, the highest point of the internal dust removal plate 17 is positioned on the first fixed support plate 161. Then, by starting the hoisting equipment, the internal dust removal plate 17 gradually descends due to the longitudinal movement limiting effect of the second fixed support plate 162, so as to achieve a stable downward movement of the internal dust removal plate 17 until the internal dust removal plate 17 moves to the bottom. By starting the dust removal mechanism, the dust adhering to the vent 14 is blown off, thereby cleaning the dust on the vent 14.

[0037] Furthermore, a damping limiting groove 164 is provided on the internal dust removal plate 17. A damping shaft 165 is rotatably mounted inside the damping limiting groove 164 via a damper. A rotating gear 166 is fixed on the damping shaft 165. A fixed rack 168 is fixed between the first fixed support plate 161 and the second fixed support plate 162, and the fixed rack 168 and the rotating gear 166 are meshed and connected to control the speed of the internal dust removal plate 17 when it descends. At the same time, a limiting strip 167 is fixed on the side of the internal dust removal plate 17. The limiting strip 167 is slidably connected to the second fixed support plate 162. When the internal dust removal plate 17 moves longitudinally, the limiting strip 167 slides longitudinally on the second fixed support plate 162. At this time, the rotating gear 166 limits the moving speed of the internal dust removal plate 17 under the action of the fixed rack 168.

[0038] The dust removal mechanism includes nozzle rows 1610. Several nozzle rows 1610 are evenly arranged inside the internal dust removal plate 17. The nozzle rows 1610 are connected to the output end of a micro air pump through a connecting air pipe 169. The micro air pump delivers gas to the nozzle rows 1610 through the connecting air pipe 169, thereby blowing the ventilation openings 14 near the nozzle rows 1610 to facilitate the removal of dust on the ventilation openings 14 and reduce the amount of dust falling into the electrical cabinet 12.

[0039] The hoisting equipment includes a bidirectional motor 1611, with drive shafts 1612 at each of the two output ends of the bidirectional motor 1611. A winding roller 1613 is fixed on the drive shaft 1612, and a hoisting steel wire 1614 is wound on the winding roller 1613. The hoisting steel wire 1614 is installed on the hoisting ends 163 on the inner dust removal plate 17 and the outer dust removal plate 15, respectively. In use, the bidirectional motor 1611 is started, which drives the drive shaft 1612, so that the winding roller 1613 can be rotated, thereby realizing the winding of the hoisting steel wire 1614, and thus controlling the height of the inner dust removal plate 17 and the outer dust removal plate 15.

[0040] As a further embodiment of this application, a humidity monitoring probe 18 is fixed on the external dust removal plate 15. The humidity monitoring probe 18 sends the obtained data to the humidity display 19 for direct display of the data. Based on the data, the internal dust removal plate 17 is controlled so that the internal dust removal plate 17 blocks the vent 14 downwards and provides a warning for the situation, thereby reducing the amount of water entering the electrical cabinet 12.

[0041] In use, when cleaning dust inside the electrical cabinet 12, the damping force required by the damping shafts 165 on the external dust removal plate 15 and the internal dust removal plate 17 is first adjusted. Then, the bidirectional motor 1611 is started, and under the gravity of the external dust removal plate 15 and the internal dust removal plate 17, the internal dust removal plate 17 falls at a relatively fast and uniform speed onto the vent 14. A micro air pump is used to deliver gas through the connecting air pipe 169 to the nozzle 1610, thereby blowing the vent 14 near the nozzle 1610, which facilitates blowing the dust on the vent 14 to the outside of the electrical cabinet 12. At this time, the external dust removal plate... The damping force of the outer dust collector 15 is greater than that of the inner dust collector 17, causing the outer dust collector 15 to slowly descend to the position of the vent 14. During this process, as the outer dust collector 15 descends, the rotating gear 166 gradually meshes with the fixed rack 168, thereby causing the electrical cabinet 12 to vibrate. This vibration causes the dust adhering to the vent 14 to fall off, and after falling off, it is blown to the outside of the electrical cabinet 12 by the action of the nozzle 1610. After the dust on the vent 14 is cleaned, the start of the bidirectional motor 1611 controls the outer dust collector 15 and the inner dust collector 17 to rise to the highest position.

[0042] Dust sensor 1 is used to detect the dust concentration inside electrical cabinet 12. After detection, the dust concentration value is transmitted to microcontroller 2. Microcontroller 2 displays the dust concentration value on dust concentration display screen 3 and monitors the dust concentration value. When the dust concentration value is higher than the preset value, microcontroller 2 activates relay module 4 to control the unidirectional exhaust fan 5 for exhaust. Then, microcontroller 2 controls relay module 6 to start, thereby activating the purification function of electronic purification device 7. Microcontroller 2 activates relay module 8, thereby activating the red running light 9. When the dust concentration value is lower than the preset value, microcontroller 2 activates relay module 10, thereby activating the green standby light 11.
