[0040] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0041] like Figure 1 and Figure 2 , Figure 5 As shown, a skid-mounted hydrogen compression device in one embodiment of the utility model includes:

[0042] A skid 1, the skid 1 is a rectangular frame, and a lifting unit 2 is provided at four right-angled inner sides of the rectangular frame, the lifting unit 2 comprises a lifting seat 21 fixedly mounted on the skid 1, a rotating member 22 rotatably connected to the lifting seat 21, and a lifting lug 23 provided on the rotating member 22; specifically, the lifting seat 21 is welded to the skid 1;

[0043] The hydrogen delivery unit 3 comprises a first gas pipe 31 and a second gas pipe 32 which are connected in sequence;

[0044] A compression device 4, arranged on the bottom skid 1, for compressing the hydrogen introduced into the first air pipe 31, and introducing the compressed hydrogen into the second air pipe 32;

[0045] The cooling component 5 is arranged on the skid 1 and is used for cooling the hydrogen in the second gas pipe 32 .

[0046] The skid-mounted hydrogen compression equipment has a compact structure and occupies a small volume by centrally assembling the hydrogen delivery unit 3, the compression device 4 and the cooling component 5 on the bottom skid 1. At the same time, by arranging a lifting unit 2 on the four right-angled inner sides of the rectangular frame, the lifting ears 23 of the lifting unit 2 cooperate with the crane in the production workshop to facilitate lifting and transfer, thereby improving production efficiency.

[0047] like Figure 2 and Figure 3 As shown, in one embodiment, the lifting ear 23 is connected to the lifting seat 21 through a cam structure 24, and the cam structure 24 includes a convex arc portion 241, a flat arc portion 242, and a contact portion 243 provided on the lifting seat 21. In this way, by rotating the rotating member 22, the convex arc portion 241 or the flat arc portion 242 contacts the contact portion 243, thereby switching the position of the lifting ear 23.

[0048] In one embodiment, the lifting lug 23 is threadedly connected to the rotating member 22. In this way, different lifting lugs 23 can be replaced according to the size of the hook of the crane in the production workshop, thereby improving the adaptability of the lifting unit 2; at the same time, when the skid-mounted hydrogen compression equipment is working stably and does not need to be hoisted, the lifting lug 23 can be removed and reused, thereby reducing production costs.

[0049] In one embodiment, the compression device 4 includes a hydraulic component 41 and a compression component 42. The hydraulic component 41 includes a hydraulic support 411, a hydraulic oil tank 412 disposed on the hydraulic support 411, and a hydraulic pump 413 disposed below the hydraulic oil tank 412; the compression component 42 includes a hydraulic cylinder 421 connected to the hydraulic pump 413 through a hydraulic pipeline 43. In this way, the hydraulic oil in the hydraulic oil tank 412 is pumped to the hydraulic cylinder 421 through the hydraulic pump 413, and the hydraulic cylinder 421 compresses hydrogen through a cylinder plug rod and passes the hydrogen into the cooling component 5.

[0050] In one embodiment, the cooling component 5 includes a water inlet pipe 51, a cooling pipe 52, and a water outlet pipe 53 which are connected in sequence; the second air pipe 32 is arranged inside the cooling pipe 52. In this way, cooling water is passed from the water inlet pipe 51 to the cooling pipe 52 by a water pump, and the heat generated by the compression of hydrogen in the second air pipe 32 is quickly taken away by the flowing cooling water, and the heat is taken away from the water outlet pipe 53 along with the flowing water.

[0051] In one embodiment, the hydraulic component 41, the cooling pipe 52, and the compression component 42 are arranged in sequence in the width direction of the bottom skid 1. In this way, the skid-mounted hydrogen compression equipment has a compact structure and reduces the occupied volume.

[0052] In one embodiment, an instrument component 6 is further included, and the instrument component 6 is arranged in an instrument box 61 above the cooling component 5, and a plurality of numerical displays 62 are arranged on the instrument box 61. In this way, the numerical displays 62 are used to display the hydraulic pressure value, the hydrogen pressure value, and the hydrogen temperature value, so as to ensure that each component can work in a stable working state and ensure the safety of the skid-mounted hydrogen compression equipment.

[0053] In one embodiment, the compression component 42 further includes an oil collecting unit 422 disposed below the hydraulic cylinder 421, and the oil collecting unit 422 includes an oil collecting box for collecting oil leaked from the hydraulic cylinder 421. Since the hydraulic oil pressure of the hydraulic cylinder 421 is relatively high, a small amount of hydraulic oil may leak during long-term use. By providing an oil leakage hole in the hydraulic cylinder 421 to release part of the excess pressure and hydraulic oil, safety in use is ensured. In this way, the hydraulic oil leaked from the hydraulic cylinder 421 is collected by the oil collecting unit 422, thereby avoiding waste of hydraulic oil and environmental pollution, and saving energy and protecting the environment.

[0054] In one embodiment, a plurality of buffer pads 7 are further provided at the bottom of the skid 1. Specifically, the buffer pads 7 at least include rubber blocks provided at four corners of the bottom of the skid 1. Thus, the buffer pads 7 are used to prevent the skid-mounted hydrogen compression equipment from being in hard contact with the ground during the hoisting and placement process, thereby preventing damage to components.

[0055] In one embodiment, it further comprises a distribution box 8 arranged on the bottom skid 1. Specifically, the distribution box 8 is arranged next to the hydraulic oil tank 412. In this way, the skid-mounted hydrogen compression equipment has a compact structure and reduces the occupied volume.

[0056] In one embodiment, it further includes moving wheel units arranged at four corners of the bottom of the bottom skid 1. In this way, after the skid-mounted hydrogen compression equipment is assembled, the moving wheel units are installed to facilitate the translation of the skid-mounted hydrogen compression equipment on the ground.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
