DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] According to an embodiment of the present invention, a mobile dust-free workshop for assembling large transformers is provided. Figures 1 to 6 , including: a ventilation device 1, a filtering device is arranged inside the ventilation device 1, the ventilation device 1 includes an air supply port 11 located at the top of the mobile dust-free workshop, the air supply port 11 is connected to the filtering device, and the air outlet direction of the air supply port 11 is arranged toward the ground of the mobile dust-free workshop; an air outlet 2, the air outlet 2 is opened on the wall of the mobile dust-free workshop, and the air outlet 2 is located at one end of the wall close to the ground.

[0024] By setting up the ventilation equipment 1, the filtering device in the ventilation equipment 1 can effectively remove pollutants such as dust in the air, ensure the cleanliness of the air entering the mobile dust-free workshop, and the filtered clean air enters the interior of the mobile dust-free workshop through the air supply port 11. The air supply port 11 is located at the top of the mobile dust-free workshop, and the air outlet direction is toward the ground. This design can make the purified air flow vertically downward to the ground, so that the air is evenly distributed in the mobile dust-free workshop, effectively covering the entire working area, so that a positive pressure environment is formed in the mobile dust-free workshop. The air outlet 2 is opened on the wall of the mobile dust-free workshop and is located at one end of the wall close to the ground. The position design of the air outlet 2 is conducive to discharging the dirty air containing dust in the mobile dust-free workshop. When positive pressure is formed in the mobile dust-free workshop, the positive pressure environment can prevent external dust and pollutants from entering the mobile dust-free workshop. The air will flow to the outside of the mobile dust-free workshop through the air outlet 2 at the bottom instead of entering from the outside, thereby maintaining the cleanliness of the inside of the mobile dust-free workshop, thereby forming a "dust-free workshop" inside the mobile dust-free workshop, solving the technical problem in the related technology that the traditional workshop environment cannot ensure that the assembly process of large transformers is carried out in a clean environment.

[0025] In some embodiments, see Figure 4 The ventilation device 1 includes a device body, which is connected to the air supply port 11 and the air inlet 12 respectively. The device body is installed on the top of the mobile dust-free workshop, the air supply port 11 is located above any door body 51, and the device body and the air inlet 12 are located in the middle position of the mobile dust-free workshop.

[0026] In the mobile dust-free workshop of this embodiment, see Figure 1 A barrier layer 3 is provided at the air outlet 2, and the shape of the barrier layer 3 matches the shape of the air outlet 2. The barrier layer 3 is used to prevent the air outside the mobile clean room from entering the mobile clean room through the air outlet 2.

[0027] By setting the barrier layer 3, the barrier layer 3 can effectively block the air outside the mobile clean room from flowing back into the mobile clean room through the air outlet 2, thereby preventing pollutants such as dust and microorganisms in the external environment from entering the mobile clean room. However, since the air pressure inside the mobile clean room is higher than that of the external environment, the air inside the workshop can be output to the outside of the mobile clean room through the barrier layer 3, so that the dirty air at the bottom of the mobile clean room is discharged.

[0028] In the mobile dust-free workshop of this embodiment, see Figure 1The barrier layer 3 includes a brush, one end of which is connected to the wall of the mobile clean room, and the other end of which is in contact with the ground. By setting the brush, one end of which is connected to the wall of the mobile clean room, and the other end of the barrier layer 3 is in contact with the ground, it is ensured that the brush can completely block the air outlet 2, and external air and pollutants are prevented from entering the mobile clean room as much as possible. Since the brush is made of flexible material, it can also avoid obstacles when the mobile clean room moves.

[0029] In this way, during the assembly of large transformers, clean air flows vertically downward from the air supply port 11 of the ventilation equipment 1 to the bottom of the mobile dust-free workshop, creating a positive pressure environment inside the mobile dust-free workshop, and flows to the outside of the mobile dust-free workshop through the gaps between the brushes installed at the bottom of the mobile dust-free workshop, bringing pollutants out of the mobile dust-free workshop. It is not easy to generate eddy currents and turbulent currents, and newly generated pollutants can be quickly taken away, so that the cleanliness of the mobile dust-free workshop can be quickly restored. At the same time, the ventilation equipment 1 can be used to control the temperature and humidity in the mobile dust-free workshop to meet the strict requirements of large transformer assembly on environmental temperature and humidity.

[0030] In the mobile dust-free workshop of this embodiment, see Figure 1-2 The wall includes: a first wall 41 and a third wall 43 which are arranged opposite to each other, and an air outlet 2 is arranged on the first wall 41 and the third wall 43; a second wall 42 and a fourth wall 44 which are arranged opposite to each other, and a connecting port 5 is respectively opened on the second wall 42 and the fourth wall 44, and a door body 51 is respectively installed on the connecting port 5, and the door body 51 can be opened and closed; wherein, the first wall 41, the second wall 42, the third wall 43 and the fourth wall 44 are connected end to end in sequence.

[0031] In some embodiments, the door body 51 is an electric rolling door, which is controlled by a motor to be folded or unfolded, and an encoder is configured to identify the degree of opening and closing of the rolling door.

[0032] In some embodiments, a transparent viewing window is provided on the door body 51 to facilitate observation of the specific conditions inside the mobile dust-free workshop.

[0033] In this way, the large transformer and the assembly platform enter or leave the mobile dust-free workshop through the door body 51. In actual production, the large transformer is first transferred to the assembly station by lifting equipment. The assembly station is generally equipped with an assembly platform. Then the mobile dust-free workshop is moved to the assembly station so that the large transformer and the assembly platform are both located inside the mobile dust-free workshop. After that, the door body 51 can be closed and the ventilation equipment 1 can be turned on to create a positive pressure environment in the mobile dust-free workshop.

[0034] In the mobile dust-free workshop of this embodiment, see Figure 1The mobile cleanroom includes: a driving wheel 6, which is rotatably arranged and in contact with the ground, wherein the driving wheel 6 includes a plurality of driving wheels, and the plurality of driving wheels 6 are respectively arranged at one end of the first wall 41 and the third wall 43 close to the ground; and a walking driving device 61, which is respectively connected to the plurality of driving wheels 6 to drive the plurality of driving wheels 6 to rotate. The entire mobile cleanroom structure is supported by the plurality of driving wheels 6, and the mobile cleanroom realizes the walking function.

[0035] Specifically, the travel drive device 61 includes a drive motor and a reducer.

[0036] It is understandable that a track may be provided on the ground to facilitate the movement of the mobile clean room and guide the movement of the mobile clean room.

[0037] In the mobile dust-free workshop of this embodiment, the mobile dust-free workshop includes: a dust collector, which is arranged on the first wall 41 and / or the third wall 43 of the mobile dust-free workshop, and is used to collect the air inside the mobile dust-free workshop; a dust detection component, and the dust detection component is used to detect the dust content in the air inside the mobile dust-free workshop. By setting the dust collector and the dust detection component, the dust content inside the mobile dust-free workshop is detected, so as to monitor the air cleanliness in real time, and the detection result will be fed back to the user through the alarm module or the visualization module. The user can inspect and maintain the mobile dust-free workshop according to the detection structure, or check whether the conditions for starting assembly are met.

[0038] In some embodiments, the specific content of dust is measured by a dust weight high-precision analytical balance.

[0039] In some embodiments, the dust collector and the dust detection component are installed on the first wall 41 or the third wall 43 , specifically, located at a lower portion of the first wall 41 or the third wall 43 .

[0040] In some embodiments, the mobile clean room further includes a temperature and humidity detection device to monitor the temperature and humidity conditions in the mobile clean room in real time.

[0041] In the mobile dust-free workshop of this embodiment, see Figure 4-5 The mobile cleanroom includes: a visual inspection device 7, which is arranged inside the mobile cleanroom and is used to collect images inside the mobile cleanroom; a main control module, which is connected to the visual inspection device 7 by signal, and is used to analyze and record images inside the mobile cleanroom; and an alarm module, which is connected to the main control module by signal, and sends out an alarm according to the images inside the mobile cleanroom.

[0042] In some embodiments, the visual inspection device 7 includes a monitoring camera that can take photos and videos of the interior of the mobile dust-free workshop.

[0043] In some embodiments, the visual inspection device 7 is located above any door body 51 to facilitate the capture of the entire mobile dust-free workshop.

[0044] Through the above settings, the visual detection device 7 collects images inside the mobile clean room, and can monitor the behavior of personnel and equipment, supervise whether the operation of personnel in the mobile clean room complies with the specifications, such as whether the clean clothes are worn correctly, whether the operation is carried out according to the prescribed process, etc. At the same time, the operating status of the equipment can be monitored, and equipment failures or abnormal operation conditions can be discovered in time to reduce the risk of pollution caused by human factors and equipment problems; various events in the mobile clean room, personnel entry and exit records, equipment operation records, etc. are recorded through the main control module. These records are helpful for tracing and analyzing when quality problems occur in the product, and finding possible causes so as to take corresponding measures for improvement. The main control module has a local large-capacity storage function and can store monitoring data in real time. In addition, the main control module has a high-speed wireless transmission function. The main control module adopts high-speed wireless transmission technology to quickly transmit monitoring data to the remote monitoring center, which is convenient for managers to view the situation in the workshop in real time. The main control module has a built-in AI chip, which can analyze the monitoring screen in real time, automatically identify personnel behavior, abnormal equipment status, etc. If it is detected that the personnel are not dressed according to the specifications or the equipment is smoking, the alarm module is immediately controlled to sound an alarm and push notifications.

[0045] In the mobile dust-free workshop of this embodiment, see Figure 1 The mobile cleanroom includes a visualization module, which is respectively connected to the visual inspection device 7 and the main control module by signal, and includes a display screen 71, which is arranged on the outer surface of the first wall 41 and / or the third wall 43. Through the above arrangement, the screen 71 can view the images collected by the visual inspection device 7 in real time, and the SOP required for the current assembly operation can be viewed through the display screen 71, as well as display parameters such as the current cleanliness, temperature and humidity of the mobile cleanroom.

[0046] In some embodiments, the visualization module includes a status display board 73, which can be used to indicate the working status of the mobile dust-free workshop by changing colors, for example, using different colors to indicate working, stopped working, dust exceeding the standard, etc.

[0047] In the mobile dust-free workshop of this embodiment, see Figure 1The mobile dust-free workshop includes a power module, which includes a plurality of electrical interfaces 72, which are respectively arranged on the inner walls of the first wall 41 and the third wall 43. By arranging the electrical interfaces 72, it is convenient to power the equipment required for the assembly operation.

[0048] In some embodiments, the power module further includes an electrical control box.

[0049] In the mobile clean room of this embodiment, the mobile clean room includes a lighting lamp, and the lighting lamp includes a plurality of lighting lamps, and the plurality of lighting lamps are arranged at intervals on the top of the mobile clean room.

[0050] In the mobile dust-free workshop of this embodiment, see Figure 1-3 The mobile dust-free workshop includes: a connecting block 81, which is installed on the outer surface of the fourth wall 44, and the connecting block 81 is movably arranged in a direction parallel to the fourth wall 44; a connecting plate 82, which is protrudingly arranged on the outer surface of the second wall 42, and the connecting plate 82 is perpendicular to the second wall 42. A connecting groove 821 is opened on the connecting plate 82, and the connecting groove 821 is used to accommodate the connecting block 81.

[0051] In some embodiments, see Figure 3 The connecting block 81 and the connecting groove 821 each include a plurality of connecting blocks 81, and the plurality of connecting blocks 81 are fixed on a bottom plate, and the bottom plate is controlled to reciprocate by a cylinder.

[0052] In some embodiments, a shielding plate is provided on the fourth wall 44 to shield structures such as the plurality of connection blocks 81 , the bottom plate and the cylinder.

[0053] Specifically, in actual production, the scale and output of transformer assembly may change. Large transformers have various scales, such as 3 meters, 5 meters, and 10 meters. By setting connecting blocks 81 and connecting plates 82, splicing interfaces are reserved for assembling mobile dust-free workshops. By expanding the mobile dust-free workshop through the reserved interfaces, the length of the mobile dust-free workshop can be flexibly adjusted to meet the production needs of different scales, avoiding the situation where production is restricted due to insufficient mobile dust-free workshops.

[0054] Specifically, when different mobile clean rooms are spliced, the connection block 81 is controlled to extend so that the connection block 81 enters the connection groove 821, so that the spliced ​​mobile clean rooms become a whole, avoiding the formation of gaps between two adjacent rooms and preventing a large amount of external air from entering the mobile clean room.

[0055] One-way valves 13 are respectively provided at the air supply port 11 , the air inlet 12 and the first connecting pipe 14 to control the ventilation device body to communicate with the air supply port 11 , the air inlet 12 or the first connecting pipe 14 .

[0056] In some embodiments, see Figure 4 When different mobile dust-free workshops are spliced, all splicing workshops can share one ventilation device 1, and the other ventilation devices 1 are turned off to save resources. The working ventilation device 1 can be connected to the air inlet of other workshops through a first connecting pipe 14, for example. Figure 4 In the figure, by setting the first connecting duct 14 and the series return air duct, two mobile dust-free workshops can be spliced. During the splicing process, the air supply port 11, the air inlet 12 and the ventilation equipment body of the first mobile dust-free workshop work normally. The one-way valve 13 on the first connecting duct 14 in the first workshop is opened, and the one-way valve at the air supply duct 15 of the second workshop is opened at the same time, so that clean air flows to the air supply port of the second workshop, the one-way valve at the air inlet 12 of the second workshop is closed, and the one-way valve on the second connecting duct is opened, so that the air in the second workshop enters the first mobile dust-free workshop ventilation equipment 1 for purification.

[0057] It is understandable that by adding connecting pipelines in the ventilation pipeline, a larger number of workshops can be spliced ​​to realize the shared ventilation equipment 1.

[0058] In the mobile dust-free workshop of this embodiment, see Figure 1 The mobile dust-free workshop comprises: a sealing groove provided at the first connecting port 5 or the second connecting port 5, and a sealing ring 9 is embedded in the sealing groove. By providing the sealing ring 9, when different mobile dust-free workshops are spliced, the pipes between two adjacent mobile dust-free workshops are connected in series and interconnected with each other, which can prevent leakage of the air supply airflow and ensure that the air supply airflow reaches all the mobile dust-free workshops.

[0059] In some embodiments, see Figure 6 A sealing ring 9 is also provided on the second wall 42 or the fourth wall 44 to further ensure the sealing between two adjacent workshops.
