A ventilation duct is fixedly connected to the inner wall of the protective shell, a protective cover is fixedly connected to the right side of the ventilation duct, and a second dustproof net is fixedly connected to the left side of the ventilation duct. An electrostatic adsorption plate is fixedly connected to the inner top wall of the protective shell, and a drive motor is located above the plate. A dust alarm is fixedly connected to the inner bottom wall of the protective shell. This dustproof protective shell, by incorporating a dust alarm, controller, ventilation duct, drive motor, fan blades, protective cover, and second dustproof net, allows the dust alarm to alert the controller when excessive dust accumulates inside the protective shell, enabling the dust to be extracted.
[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned dustproof protective shell: the existing technology simply sets up an exhaust device and then sets up a filter mechanism to filter the air to achieve dust prevention during ventilation. In actual use, the filter cotton needs to be replaced frequently, which is time-consuming and labor-intensive. Moreover, when replacing the filter cotton, the exhaust device needs to be stopped, which will cause the equipment temperature to rise to a certain extent. Based on this, this utility model designs a dustproof protection mechanism for electromechanical equipment to solve the above problems. Utility Model Content

[0021] 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.
[0022] This utility model provides, for example Figure 1-4The dust protection mechanism for electromechanical equipment shown includes a protective housing 1. An exhaust fan 14 is installed on one side wall of the protective housing 1. Air inlets are provided on the protective housing 1, allowing external air to enter the interior of the protective housing 1. A support shaft 2 is movably engaged with the protective housing 1. A support base plate 7 is installed at one end of the support shaft 2, and dustproof components 8 are installed on the support base plate 7. A fixed bracket 3 is installed on the inner side wall of one side of the protective housing 1. A drive sleeve 4 is rotatably connected to the fixed bracket 3, and the support shaft 2 is located inside the drive sleeve 4. Limiting strips 5 are installed on the side wall of the support shaft 2, and the limiting strips 5 are slidably engaged with the drive sleeve 4. When the drive sleeve 4 is rotated, the limiting strips 5 synchronously drive the support shaft 2 to rotate. A drive assembly 6 for rotating the drive sleeve 4 is installed on one inner wall of the protective housing 1. A tension plate 13 is slidably engaged on the support shaft 2. A support side plate 10 is installed on one inner wall of the protective housing 1. An electric telescopic rod 11 is installed on the bottom outer wall of the support side plate 10. A push block 12 for moving the tension plate 13 is connected to the output end of the electric telescopic rod 11. One side of the push block 12 is inclined. When the push block 12 is moved upward, the tension plate 13 can be moved through the inclined surface on the push block 12. The dustproof assembly 8 includes a support housing 801, which is located on one side wall of the support base plate 7. A filter cotton 802 is provided inside the support housing 801. A limit plate 803 is engaged on the support housing 801. Threaded rods 804 are installed on both sides of the support housing 801. Locking nuts are connected to the threads on the outer surface of the threaded rods 804. By loosening the locking nuts, the limiting plate 803 can be removed, thus allowing the limiting plate 803 to be removed. Then, the filter cotton 802 inside the support housing 801 can be replaced. When using this device, the exhaust fan 14 first draws air through the filter cotton 802 inside the dustproof assembly 8 before it enters the protective housing 1. After a period of use, when excessive dust accumulates on the filter cotton 802, the electric telescopic rod 11 lowers the push block 12, causing it to stop pressing against the tension plate 13. This prevents the support base plate 7 at one end of the support shaft 2 from moving the dustproof assembly. The dustproof assembly 8 rests against the side wall of the protective housing 1, which in turn drives the drive sleeve 4 to rotate. The drive sleeve 4 then drives the support shaft 2 to rotate, which in turn drives the support base plate 7 to rotate. By rotating the support base plate 7 90 degrees, the other two dustproof components 8 can be aligned with the air inlet. Then, the electric telescopic rod 11 drives the push block 12 to rise, allowing the push block 12 to push the tension plate 13 to move. The tension plate 13 then drives one end of the support shaft 2 to move, allowing the support base plate 7 to push the dustproof components 8 against the side wall of the protective housing 1. Therefore, the filter cotton 802 inside the dustproof components 8 can be replaced only when all four dustproof components 8 have reached the end of their service life, thus extending the interval between manual replacements of the filter cotton 802.Furthermore, when replacing filter cotton 802, the filter cotton 802 in two of the dustproof components 8 can be replaced first. Then, the replaced dustproof components 8 can be rotated to the air inlet position on the protective housing 1. Next, the filter cotton 802 inside the other two dustproof components 8 can be replaced. Therefore, the device does not require stopping ventilation when replacing filter cotton 802, and thus will not cause the equipment temperature to rise in a short period of time.
[0023] In this embodiment, as Figure 2 As shown, a sealing ring 805 is installed on one side wall of the support housing 801. The sealing ring 805 is made of rubber. When the dustproof component 8 is pressed against the side wall of the protective housing 1, the sealing ring 805 is compressed, which can improve the sealing between the dustproof component 8 and the side wall of the protective housing 1.
[0024] In this embodiment, as Figure 4 As shown, guide rods 9 are installed on one inner wall of the protective box 1. The tension plate 13 is slidably engaged with the guide rods 9. The tension plate 13 is slidably engaged with the guide rods 9 through a linear bearing. The guide rods 9 can guide the tension plate 13, so that the tension plate 13 can always slide stably on the support shaft 2.
[0025] In this embodiment, as Figure 4 As shown, the drive assembly 6 includes a motor bracket 601, which is located on one inner wall of the protective housing 1. A drive motor 602 is mounted on one side wall of the motor bracket 601. A drive pulley 603 is connected to the output end of the drive motor 602. A driven pulley 604 is mounted on the side wall of the drive sleeve 4. The drive pulley 603 is connected to the driven pulley 604 via a transmission belt. The drive motor 602 drives the drive pulley 603 at its output end to rotate, so that the driven pulley 604 can drive the drive sleeve 4 to rotate.
[0026] In this embodiment, as Figure 1 As shown, a protective cover 15 is installed on one side wall of the protective housing 1, and a limit cover 16 is installed on one side wall of the protective cover 15. The limit cover 16 is equipped with a filter cotton 17. The filter cotton 17 helps to prevent dust from entering the interior of the protective housing 1 from the exhaust fan 14.
[0027] Working principle of this utility model: This utility model is a dust protection mechanism for electromechanical equipment. Air is drawn in by the exhaust fan 14, filtered by the dustproof component 8, and then enters the interior of the protective housing 1. After the dustproof component 8 has been used for a period of time, the electric telescopic rod 11 first drives the push block 12 to descend, so that it no longer presses against the tension plate 13. This prevents the support base plate 7 at one end of the support shaft 2 from pressing the dustproof component 8 against the side wall of the protective housing 1. Then, by driving the drive sleeve 4 to rotate, the drive sleeve 4 can drive the support shaft 2 to rotate, which in turn drives the support base plate 7 to rotate. By rotating the support base plate 7 90 degrees, the other two dustproof components 8 can be aligned with the air inlet. Finally, the electric telescopic rod 11 drives the push block 12 to rise, so that... Push block 12 can push tension plate 13 to move, thereby enabling tension plate 13 to drive one end of support shaft 2 to move, thereby enabling support base plate 7 to drive dustproof component 8 to abut against the side wall of protective box 1. When the service life of all four dustproof components 8 is exhausted, the filter cotton 802 inside the dustproof component 8 can be replaced. Therefore, this device can extend the time for manual replacement of filter cotton 802. When replacing filter cotton 802, the filter cotton 802 inside two of the dustproof components 8 can be replaced first, and then rotated to the position of air inlet on the protective box 1 before replacing the filter cotton 802 inside the other two dustproof components 8. Therefore, this device will not cause the temperature of the equipment to rise in a short time when replacing filter cotton 802.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
