[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] See also Figures 1 to 4The utility model discloses a compressor skid, including a base 100, on which a compressor 400, a first rotary drive mechanism 500, an oil separator 600 and a plurality of lifting drive mechanisms 200 are arranged, the output end of the first rotary drive mechanism 500 is transmission-connected with the compressor 400, and the first rotary drive mechanism 500 drives the compressor 400 to rotate; lubricating oil and medium compressed gas are arranged in the compressor 400, and the oil separator 600 is communicated with the compressor 400. When the compressor 400 rotates, that is, when the compressor 400 works, the compressor 400 drives the lubricating oil and the medium compressed gas to enter the oil separator 600, and the oil separator 600 separates the lubricating oil and the medium compressed gas, and the separated lubricating oil is discharged back into the compressor 400, and the separated medium compressed gas is used for conveying to an external refrigeration circuit, and then the medium compressed gas re-enters the compressor 400, and the lubricating oil and the medium compressed gas are continuously circulated, thereby completing the refrigeration work with other refrigeration equipment in the external refrigeration circuit.

[0035] The lifting drive mechanism 200 drives the wheels 300 to rise and fall. When the lifting drive mechanism 200 drives the wheels 300 to descend, the wheels 300 are against the ground and can lift the base 100 from the ground. At this time, the entire compressor skid is placed on the ground through multiple wheels 300, and the compressor skid can be easily driven to move on the ground; and when the compressor skid moves to a fixed or temporary working position, the lifting drive mechanism 200 drives the wheels 300 to rise, the base 100 contacts the ground, and the base 100 will support the compressor 400, the first rotary drive mechanism 500, the oil separator 600 and multiple lifting drive mechanisms 200. At this time, the wheels 300 can be against the ground or hung on the base 100.

[0036] The compressor skid can be moved on the ground by wheels 300, and the entire compressor skid can be moved conveniently and quickly without the use of lifting equipment, thus saving time, effort and cost. The compressor skid can be used in conjunction with a carbon dioxide storage tank in transit or temporarily fixed, and can support the use of other equipment that requires refrigeration, and is suitable for a variety of occasions.

[0037] The exhaust port of the compressor 400 is connected to the inlet of the oil separator 600 through the first flexible pipe. The lubricating oil and the medium compressed gas in the compressor 400 pass through the exhaust port of the compressor 400, the first flexible pipe and the inlet of the oil separator 600 in sequence, thereby transporting the lubricating oil and the medium compressed gas into the oil separator 600.

[0038] See also Figure 1A cooler 700 for cooling the lubricating oil is provided at the bottom of the oil separator 600. The oil discharge port of the oil separator 600 is connected to the inlet of the cooler 700 through a pipeline, and the outlet of the cooler 700 is connected to the lubricating oil inlet of the compressor 400 through a second flexible pipe. The lubricating oil separated by the oil separator 600 passes through the oil discharge port of the oil separator 600, the pipeline, the inlet of the cooler 700, the cooler 700, the outlet of the cooler 700, the second flexible pipe and the lubricating oil inlet of the compressor 400 in sequence, so as to discharge the lubricating oil back into the compressor 400. The lubricating oil is cooled in the cooler 700 to avoid excessive temperature of the lubricating oil, thereby ensuring the service life of the lubricating oil. The lubricating oil lubricates the compressor 400 and absorbs part of the heat of the compressor 400 to ensure the normal operation of the compressor 400.

[0039] When the compressor 400 is working, its vibration frequency and amplitude are relatively large, and the noise is relatively large. The setting of the first flexible pipe can prevent the compressor 400 from transmitting all the vibrations to the oil separator 600, and prevent the oil separator 600 from vibrating greatly, thus playing a role in shock absorption and noise reduction. Similarly, the second flexible pipe also plays a role in shock absorption and noise reduction, protecting the surrounding environment and human health. It ensures the connection reliability between the compressor 400 and the oil separator 600 and the cooler 700, slows down the damage speed of each component, reduces the later maintenance cost, and improves the life and reliability of each component.

[0040] In some embodiments, the first flexible tube and the second flexible tube are both corrugated tubes or hoses.

[0041] See also Figure 1 and Figure 3 In some embodiments, a plurality of detachable support frames 110 are provided on the base 100, and the base 100 is connected to the lifting drive mechanism 200 through the support frames 110. The lifting drive mechanism 200 and the wheels 300 can be removed from the base 100 or installed on the base 100 through the support frames 110.

[0042] When the compressor skid needs to be moved, the support frame 110, the lifting drive mechanism 200 and the wheels 300 are installed on the base 100, and when the compressor skid does not need to be moved, the support frame 110, the lifting drive mechanism 200 and the wheels 300 can be removed from the base 100.

[0043] See also Figure 1 , Figure 3 and Figure 4In some embodiments, the lower end of the support frame 110 is connected to the upper surface of the base 100, and the upper end of the support frame 110 is connected to the lifting drive mechanism 200, so that the support frame 110 and the lifting drive mechanism 200 are higher than the base 100, and the lifting drive mechanism 200 is connected to the wheel 300 and drives the wheel 300 to rise and fall, so that the lower edge of the wheel 300 is lower than the lower surface of the base 100. At this time, the wheel 300 can support the base 100 above the ground, or make the lower edge of the wheel 300 higher than the lower surface of the base 100. At this time, the base 100 is against the ground and supported by the ground.

[0044] See also Figure 1 and Figure 3 Two avoidance openings 120 are provided on the left and right sides of the base 100. The number of the avoidance openings 120 and the number of wheels 300 are both four. The four avoidance openings 120 are distributed in a rectangular shape. The four wheels 300 are respectively arranged in the four avoidance openings 120. The wheels 300 can be raised and lowered in the avoidance openings 120. The avoidance openings 120 play the role of storing the wheels 300 to prevent the wheels 300 from protruding from the left and right sides of the base 100.

[0045] In some embodiments, the lifting drive mechanism 200 is a jack, which has a simple structure, is easy to operate and has low cost. The upper support of the jack is connected to the upper end of the support frame 110 through a first fastener, and the lower support of the jack is connected to the axle of the wheel 300 through a second fastener.

[0046] See also Figure 4 In some of the embodiments, all the screw rods of the jacks are detachably connected to a crank 800, and the screw rods of the jacks are driven to rotate by the crank 800, so that the upper support and the lower support never move away from or approach each other. When the upper support and the lower support move away from each other, the wheel 300 moves down, and when the upper support and the lower support move toward each other, the wheel 300 rises.

[0047] In another embodiment, a second rotary drive mechanism is provided on the base 100, and the output end of the second rotary drive mechanism is connected to the screw drive of the four jacks. The second rotary drive mechanism drives the screws of the four jacks to rotate synchronously, so that the four jacks drive the four wheels 300 to rise and fall synchronously without manual operation of the jacks.

[0048] See also Figure 3 In some of the embodiments, a plurality of connection structures 130 for connecting to an external traction mechanism are provided on the base 100 , and the base 100 is conveniently connected to the external traction mechanism through the connection structures 130 .

[0049] The connection structure 130 may be a hanging hole or a hanging ear.

[0050] The first fastener and the second fastener may both be a first bolt and a first nut that fit together.

[0051] The lower end of the support frame 110 is connected to the upper surface of the base 100 through a plurality of third fasteners. The third fasteners may be screws or second bolts and second nuts that cooperate with each other.

[0052] The first rotary drive mechanism 500 is a first motor. The first motor is disposed above the oil separator 600 through a first support, the compressor 400 is disposed above the oil separator 600 through a second support, the output shaft of the first motor and the input shaft of the compressor 400 are connected through a coupling, and a protective cover is provided on the first motor. The second rotary drive mechanism is a second motor.

[0053] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
