The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a screw air compressor that is easy to maintain, such as Figure 1-4 As shown, the easy-to-maintain screw air compressor includes: a base shell 1, a mounting base 2 fixedly installed on the top of the base shell 1, a mounting groove on the top of the mounting base 2, and a recess on one inner wall of the mounting groove; a mounting block 3 disposed in the mounting groove, a slot on one side of the mounting block 3, and a screw air compressor body 4 fixedly installed on the top of the mounting block 3; a protective shell 5 disposed above the base shell 1 to protect the screw air compressor body 4; a height adjustment mechanism mounted on the base shell 1 for raising and lowering the protective shell 5; and a disassembly mechanism assembled on the mounting base 2 for fixing the mounting block 3.

[0022] In this embodiment, during normal use, the screw air compressor body 4 can be inspected and maintained by opening the inspection door 15. When it is necessary to repair the internal structure of the screw air compressor body 4, it is difficult to access the internal structure of the screw air compressor body 4 through the inspection door 15 alone, and the narrow space is not conducive to maintenance by the operator. At this time, the protective shell 5 can be raised to a suitable height by the height adjustment mechanism, so as to more easily access the screw air compressor body 4 for maintenance and repair. This design greatly improves the maintainability and work efficiency of the equipment. With the use of the disassembly mechanism, the mounting block 3 can be fixed and released, so that the mounting block 3 can be removed from the mounting slot. This makes the disassembly and assembly of the screw air compressor body 4 more convenient.

[0023] In a further preferred embodiment of this utility model, the height adjustment mechanism includes: two support plates 6 fixedly installed on the inner wall of the bottom shell 1, with the same rotating shaft 7 rotatably installed on the two support plates 6; a servo motor 8 fixedly installed on the top of the bottom shell 1 by bolts; two sprockets 9 respectively fixedly sleeved on the output shaft of the rotating shaft 7 and the servo motor 8, with the same chain 10 sleeved on the two sprockets 9; two screws 11 rotatably installed on the bottom shell 1, with sleeves 12 threadedly installed on each of the two screws 11, and both sleeves 12 being fixedly connected to the protective shell 5; two first bevel gears 13 respectively fixedly installed at both ends of the rotating shaft 7; and two second bevel gears 14 respectively fixedly installed at the bottom ends of the two screws 11, with the two second bevel gears 14 meshing with the two first bevel gears 13 respectively.

[0024] In this embodiment, the height adjustment mechanism is used to raise and lower the protective shell 5. When in use, the servo motor 8 is started, and the servo motor 8 drives the rotating shaft 7 to rotate on the two support plates 6 through the chain 10 and two sprockets 9. The rotating shaft 7 drives the two first bevel gears 13 to rotate, and the two first bevel gears 13 drive the two screws 11 to rotate on the bottom shell 1 through the two second bevel gears 14. The two screws 11 drive the two sleeves 12 to move vertically, thereby raising or lowering the protective shell 5. When the protective shell 5 is raised to a higher position, maintenance personnel can more easily access the screw air compressor body 4 for maintenance and repair, which greatly improves the maintainability and work efficiency of the equipment.

[0025] In a further preferred embodiment of the present invention, the disassembly mechanism includes: a pull rod 17 slidably mounted on the mounting base 2, one end of the pull rod 17 extending into the interior of the groove; a spring 18 slidably sleeved on the pull rod 17; and a baffle 19 fixedly mounted on the pull rod 17, wherein a locking block 20 is welded onto the baffle 19, and the locking block 20 is adapted to the locking groove.

[0026] In this embodiment, the disassembly mechanism is used to fix the mounting block 3 and can also release the mounting block 3. When releasing, pull the lever 17 outward, and the lever 17 will drive the baffle 19 to squeeze the spring 18. The baffle 19 will drive the locking block 20 to disengage from the slot of the mounting block 3. After disengagement, the mounting block 3 can be removed from the mounting slot, thereby removing the screw air compressor body 4. Before removing the mounting block 3, if the lever 17 is released, the spring 18 will elastically reset the baffle 19 and the locking block 20, so that the locking block 20 re-enters the slot, thereby fixing the mounting block 3. This is quite convenient to use.

[0027] In a further preferred embodiment of the present invention, two inspection ports are provided on one side of the protective shell 5, and each of the two inspection ports is provided with an inspection door 15.

[0028] In this embodiment, the combined use of two inspection ports and two inspection doors 15 facilitates routine observation and maintenance of certain structures on the surface of the screw air compressor body 4.

[0029] In a further preferred embodiment of the present invention, the protective shell 5 has multiple heat dissipation holes on both sides, and the multiple heat dissipation holes are inclined.

[0030] In this embodiment, the heat generated by the screw air compressor body 4 can be dissipated by using multiple heat dissipation holes. The heat dissipation holes are all inclined. This design not only facilitates the discharge of heat, but also prevents external moisture and other impurities from entering the protective shell 5 through the heat dissipation holes to a certain extent.

[0031] In a further preferred embodiment of the present invention, a perforation is provided on the top of the bottom shell 1, and the perforation is located on the outside of the chain 10.

[0032] In this embodiment, the use of perforations allows the chain 10 to be fitted onto the two sprockets 9 by passing through the bottom shell 1.

[0033] In a further preferred embodiment of the present invention, filters 16 are fixedly installed on both inner walls of the protective shell 5, and the two filters 16 are respectively arranged corresponding to the plurality of heat dissipation holes.

[0034] In this embodiment, the use of two filters 16 can block dust, impurities and other particles from the external environment, preventing them from entering the interior of the protective shell 5 through the heat dissipation holes.

[0035] In summary, compared with related technologies, this solution, through the combined use of the inspection port and inspection door 15, facilitates routine observation and maintenance of certain structural components on the surface of the screw air compressor body 4 by maintenance personnel. The height adjustment mechanism enables the lifting and lowering of the protective shell 5 with minimal effort. When the protective shell 5 is raised to a suitable height, the screw air compressor body 4 is fully exposed, allowing for easier access and maintenance, significantly improving maintainability and work efficiency. Furthermore, the disassembly mechanism allows for both fixing and releasing the mounting block 3, enabling users to quickly disassemble and install the screw air compressor body 4 when needed.

[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
