[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a protective shell for a natural gas compressor unit that is easy to disassemble, including a base 1, a vertical plate 2 is connected to the top of the base 1, a plurality of external interfaces 22 are provided on the vertical plate 2, and insertion holes 23 are opened on both sides of the top of the vertical plate 2. The external interfaces 22 can facilitate the insertion and withdrawal of pipelines, thereby facilitating the assembly of pipelines by workers.

[0022] A protective cover 3 is slidably mounted on the base 1, with observation windows 18 mounted on both sides of the protective cover 3, and rollers 19 mounted on both sides below the protective cover 3. The observation windows 18 enable the staff to conveniently observe the working conditions, and the rolling of the rollers 19 can assist the staff in pushing the protective cover 3 to move, making the movement of the protective cover 3 flexible and convenient.

[0023] A compressor unit 4 is installed above the base 1, and limiting grooves 5 are provided on both sides of the base 1. Guide grooves 6 are provided on both sides above the base 1. A fixing plate 7 is connected to one side of the vertical plate 2 and the protective cover 3. A plurality of vents 20 are provided on the fixing plate 7. A shielding frame 21 is installed on the vertical plate 2. The motor 9 and the fan blades 10 are arranged between the fixing plate 7 and the shielding frame 21. The air circulation in the protective cover 3 can be promoted through the plurality of vents 20, thereby avoiding heat accumulation, and using the fan blades 10 to blow air speeds up the heat dissipation efficiency.

[0024] A fixing frame 8 is installed inside the vertical plate 2, and a motor 9 is installed on the fixing frame 8. A fan blade 10 is installed on the output shaft of the motor 9. A connecting strip 11 is connected to the bottom of the protective cover 3, and limiting plates 12 are connected on both sides of the bottom of the protective cover 3. The connecting strip 11 slides in the guide groove 6. The limiting plate 12 is designed in an L-shape as a whole and slides in the limiting groove 5. The movement of the protective cover 3 can be guided by sliding the connecting strip 11 along the guide groove 6 to prevent the protective cover 3 from deflecting during movement. During movement, the L-shaped limiting plate 12 will eventually contact the end of the limiting groove 5, thereby limiting the movement to prevent the protective cover 3 from falling off due to excessive movement.

[0025] Connecting blocks 13 are connected to both sides above the protective cover 3, and a sliding rod 14 is slidably connected to the connecting block 13. One end of the sliding rod 14 is connected to the insertion rod 15, and the other end of the sliding rod 14 is connected to the connecting plate 16. A pull rod 17 is connected above the connecting plate 16, and a spring 24 is sleeved on the sliding rod 14. One end of the spring 24 is connected to the connecting block 13, and the other end of the spring 24 is connected to the insertion rod 15. The insertion rod 15 is inserted into the socket 23. When the connecting plate 16 is pulled to make the sliding rod 14 slide on the connecting block 13, the spring 24 will be compressed. After the pull rod 17 is released, the spring 24 will rebound to make the insertion rod 15 inserted into the socket 23 for fixation. The operation is simple and convenient, which improves the disassembly and assembly efficiency.

[0026] The working principle of this utility model is:

[0027] The staff pulls the connecting plate 16 upward through the pull rod 17, causing the slide bar 14 to slide on the connecting block 13. At this time, the spring 24 will be compressed, and then the protective cover 3 is pushed to make the connecting strip 11 slide in the guide groove 6, and cause the roller 19 to roll on the ground, so that the protective cover 3 contacts the vertical plate 2. Then the pull rod 17 is released to make the spring 24 rebound, thereby pushing the insertion rod 15 into the socket 23, so that the protective cover 3 and the vertical plate 2 are fixed together. During operation, the motor 9 will rotate the fan blades 10, thereby blowing the air in the protective cover 3, causing the high-temperature air to flow out from the vent 20, and accelerating the heat dissipation efficiency. When disassembling, it is only necessary to pull the slide bar 14 upward again to cause the insertion rod 15 to disengage from the socket 23 to complete the separation of the vertical plate 2 and the protective cover 3.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
