Description

TECHNICAL FIELD

[0001] The utility model relates to hydrogen compressor technical field, specifically, relate to a base structure and hydrogen compressor. BACKGROUND

[0002] Hydrogen compressor, as its name implies, is a kind of equipment for compressing hydrogen, its main function is to compress hydrogen to the required pressure value to meet the needs of storage, transportation and application. In normal temperature and pressure state, the volumetric energy density of hydrogen is low, and the compression and delivery process is completed by changing the volume of gas through mechanical energy input.

[0003] The overall equipment of hydrogen compressor vibrates with the operation of compressor, in order to reduce vibration, usually damping parts such as rubber elastic pad are used to weaken vibration and reduce the influence of vibration. For example, the Chinese utility model with application number CN202323571796.X discloses a hydrogen compressor pipeline damping protection device, the hydrogen compressor pipeline damping protection device can slide outside the ball through the ball groove at the bottom of the pipe support assembly, and the support of the four support assemblies on the pipe support assembly can make the pipe support assembly deflect at any angle, while the ball can extrude the sliding rod, the sliding rod moves downward and extrudes the damping spring, the damping spring provides an upward support force for the sliding rod, so that the pipe support assembly can be slightly shaken, and the multi-directional damping protection effect of the pipeline is achieved, thereby greatly improving the protection effect of the hydrogen compressor pipeline.

[0004] However, the above-mentioned hydrogen compressor pipeline damping protection device only realizes the buffering and damping effect through the damping spring installed in the sliding cylinder, and the cooperation between the sliding rod and the sliding cylinder cannot provide damping and buffering effect, and the structure has room for improvement. Therefore, we propose a base structure and compressor. UTILITY MODEL CONTENTS

[0005] Therefore, in order to solve the problems existing in the existing hydrogen compressor pipeline damping protection device and better realize the damping and buffering effect of air compressor, the utility model provides a base structure and hydrogen compressor, and the specific technical scheme is as follows:

[0006] A base structure includes a base; the base structure further includes a buffer mechanism, the buffer mechanism includes a plurality of and a plurality of buffer mechanisms are respectively fixedly installed at the bottom of four corners of the base, and the buffer mechanism includes:

[0007] A guide sleeve is open at one end and closed at the other end, and is provided with a guide cavity;

[0008] A guide rod is movably connected with the guide sleeve, one end of the guide rod penetrates through the opening of the guide sleeve and extends into the guide cavity, and the other end of the guide rod is fixedly connected with the bottom of the base;

[0009] The piston is fixedly connected to one end of the guide rod and slidably sealed to the guide cavity.

[0010] An elastic component is disposed within the guide cavity, located between the bottom of the piston and the guide sleeve;

[0011] The guide cavity has multiple sets of exhaust channels on its sidewalls, and each set of exhaust channels includes at least one exhaust hole.

[0012] In the base structure, by incorporating the buffer mechanism, when the hydrogen compressor vibrates during operation, the guide rod moves axially along the guide sleeve, causing the piston to slide within the guide cavity and compress the elastic component. The elastic component provides a shock-absorbing buffer for the guide rod, base, and the hydrogen compressor mounted on the base structure, reducing compressor vibration. Furthermore, multiple exhaust channels are provided on the side wall of the guide cavity of the buffer mechanism, and the piston is slidably and sealingly connected to the guide cavity. When the piston slides within the guide cavity and compresses the elastic component, the air within the guide cavity cannot be expelled all at once due to the presence of the exhaust channels; instead, it is slowly expelled through the exhaust channels, further reducing vibration and thus further minimizing the vibration of the hydrogen compressor during operation.

[0016] Preferably, the elastic component is a helical spring.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0042] like Figure 1 as well as Figure 2 As shown, this utility model provides a base structure, including a base 1 and a buffer mechanism. A hydrogen compressor is fixedly mounted on the base 1.

[0043] The buffer mechanism comprises multiple components, and each of the multiple buffer mechanisms is fixedly installed at least at the bottom of the four corners of the base 1. That is, a buffer mechanism is installed at the bottom of each of the four corners of the base 1. Depending on actual needs, the buffer mechanism can also be installed at other locations on the base 1.

[0044] like Figure 1 As shown, the buffer mechanism includes a guide sleeve 2, a guide rod 3, a piston 4, and an elastic component 5.

[0045] The guide sleeve 2 has an open end and a closed end, and is provided with a guide cavity; the guide rod 3 is movably connected to the guide sleeve 2, with one end passing through the opening of the guide sleeve 2 and extending into the guide cavity, and the other end being fixedly connected to the bottom of the base 1.

[0046] The piston 4 is fixedly connected to one end of the guide rod 3 and is slidably and sealingly connected to the guide cavity; the elastic component 5 is disposed in the guide cavity, located between the bottom of the piston 4 and the guide sleeve 2.

[0047] The guide cavity has multiple sets of exhaust channels on its sidewalls, and each set of exhaust channels includes at least one exhaust hole 6.

[0048] Preferably, one end of the elastic component 5 is fixedly connected to the piston 4, and the other end of the elastic component 5 is fixedly connected to the bottom of the guide sleeve 2. The elastic component 5 is a helical spring.

[0049] The bottom surface of the guide sleeve 2 is provided with anti-slip texture or rubber pad to improve the stability of the base structure and prevent the base structure and hydrogen compressor from sliding due to vibration.

[0050] In the base structure, by setting the buffer mechanism, when the hydrogen compressor vibrates during operation, the guide rod 3 moves along the axial direction of the guide sleeve 2, and the piston 4 slides in the guide cavity and squeezes the elastic component 5. The elastic component 5 provides a shock-absorbing buffer for the guide rod 3, the base 1, and the hydrogen compressor mounted on the base structure, reducing the vibration of the hydrogen compressor. Multiple exhaust channels are provided on the side wall of the guide cavity of the buffer mechanism, and the piston 4 is slidably and sealingly connected to the guide cavity. When the piston 4 slides in the guide cavity and squeezes the elastic component 5, due to the existence of the exhaust channels, the air in the guide cavity cannot be discharged all at once, but is slowly discharged through the exhaust channels, which can further reduce the shock absorption and thus further reduce the vibration of the hydrogen compressor during operation.

[0051] As a preferred technical solution, the diameter of the exhaust holes 6 in the multiple sets of exhaust channels gradually decreases from the open end of the guide sleeve 2 to the closed end, and the exhaust holes 6 in each set of exhaust channels are evenly distributed along the circumference of the guide sleeve 2.

[0052] Since the diameter of the exhaust holes 6 in the multiple sets of exhaust channels gradually decreases from the open end of the guide sleeve 2 to the closed end, the buffering force provided by the guide sleeve 2, guide rod 3, and piston 4 will gradually increase as the guide rod 3 moves towards the bottom of the guide cavity, thus providing a better shock absorption effect for the hydrogen compressor. Alternatively, it can be understood that, generally speaking, if the hydrogen compressor vibrates violently, the impact force generated will increase accordingly. Since the diameter of the exhaust holes 6 gradually decreases from the open end of the guide sleeve 2 to the closed end, the air velocity discharged from the exhaust holes 6 in the guide cavity will be limited as the guide rod 3 moves towards the bottom of the guide cavity. This provides a gradually increasing reaction force on the piston 4, causing the buffering force provided by the guide sleeve 2, guide rod 3, and piston 4 to gradually increase, ultimately reducing the vibration generated by the hydrogen compressor and achieving better shock absorption.

[0053] As a preferred technical solution, the base 1 has a threaded hole at its bottom, and the guide rod 3 has an external thread that matches the threaded hole. The guide rod 3 is fixedly connected to the bottom of the base 1 through the external thread and the threaded hole.

[0054] The purpose of providing the threaded hole and the matching external thread is to allow the relative distance between the buffer mechanism and the base 1 to be adjusted according to actual needs, thereby adjusting the overall levelness of the base 1 and avoiding imbalance in the installation of the base 1 and even the hydrogen compressor due to uneven ground.

[0055] This utility model also provides a hydrogen compressor, including the aforementioned base structure.

[0056] like Figure 2 as well as Figure 3 As shown, the hydrogen compressor also includes a hydraulic oil tank 7, a hydraulic oil pump 9, a hydraulic cylinder 8, a reversing valve group 10, a suction filter 11, and a return filter 12.

[0057] A hydraulic oil tank 7 is fixedly mounted on the base structure via a bracket and is used to store hydraulic oil. A hydraulic oil pump 9 is fixedly mounted on the base structure. A directional valve assembly 10 is fixedly mounted on the bracket and is connected to the outlet of the hydraulic oil pump 9 via a hydraulic pipeline. An oil suction filter 11 is fixedly mounted in the hydraulic oil tank 7 and is connected to the inlet of the hydraulic oil pump 9 via a hydraulic pipeline. A return oil filter 12 is fixedly mounted in the hydraulic oil tank 7 and is connected to the directional valve assembly 10 via a hydraulic pipeline. A hydraulic cylinder body 8 is fixedly mounted on the base 1 and includes an oil inlet and an oil outlet. The oil inlet and outlet are connected to the directional valve assembly 10 via hydraulic pipelines. By controlling the movement of the directional valve assembly 10, the flow direction of hydraulic oil is realized, thereby controlling the movement direction of the piston 4 and piston rod within the hydraulic cylinder body 8.

[0058] The reversing valve assembly 10 is used to change the flow direction of hydraulic oil, thereby changing the flow direction of hydraulic oil flowing into the hydraulic cylinder 8, and ultimately controlling the reciprocating motion of the piston 4 by controlling the flow direction of the hydraulic oil, so as to achieve the compression of hydrogen.

[0059] By setting up the suction filter 11 and the return filter 12, the hydraulic oil can be filtered to remove impurities and prevent blockage and wear corrosion of hydraulic components.

[0060] like Figure 3 As shown, the hydrogen compressor also includes a cooling assembly 13.

[0061] The cooling assembly 13 is fixedly installed in the hydraulic oil tank 7 and is used to cool the hydraulic oil.

[0062] Specifically, such as Figure 4 As shown, the cooling assembly 13 includes a support plate 130, heat dissipation fins 131, and a spiral cooling pipe 132.

[0063] The support plate 130 is fixedly installed in the hydraulic oil tank 7; the heat dissipation fins 131 are fixedly installed in the hydraulic oil tank 7 through the support plate 130, including multiple heat dissipation fins 131 that are parallel to each other, and a hydraulic oil flow channel is formed between two adjacent heat dissipation fins 131.

[0064] The spiral cooling pipe 132 is fixedly installed on the support plate 130 and at least partially contacts each of the heat dissipation fins 131. Preferably, the spiral cooling pipe 132 includes multiple cooling pipe segments arranged in parallel from top to bottom, and each cooling pipe segment passes through each of the heat dissipation fins 131 to improve the overall cooling and heat dissipation effect.

[0065] By setting up the cooling component 13, the hydraulic oil can be cooled and dissipated, ensuring the normal operation of the hydraulic oil pump 9 and even the hydrogen compressor.

[0066] The working principle of this utility model is as follows:

[0067] In use, the hydrogen compressor is fixedly installed on the base structure, and the relative distance between the buffer mechanism and the base 1 is adjusted by rotating the guide rod 3 in the buffer mechanism. Specifically, the relative distance between the guide sleeve 2 and the base is adjusted so that the base structure and the hydrogen compressor are placed stably on the ground. When the hydrogen compressor vibrates due to operation, the base 1 vibrates accordingly. The guide rod 3 and the piston 4 move along the guide cavity and squeeze the elastic component. The elastic component provides a counterforce, and the buffer mechanism provides a shock absorption and cushioning effect, reducing the vibration of the base 1 and the hydrogen compressor. As the piston 4 moves towards the bottom of the guide cavity, air is discharged through the exhaust port 6. Since the air in the guide cavity cannot be discharged all at once, but is discharged slowly through the exhaust channel, it can further reduce the shock absorption and cushioning effect, thereby further reducing the vibration of the hydrogen compressor during operation. The diameter of the exhaust port 6 gradually decreases from the open end of the guide sleeve 2 to the closed end. As the guide rod 3 moves towards the bottom of the guide cavity, the air velocity discharged from the exhaust port 6 in the guide cavity will be limited, thereby providing a gradually increasing reaction force on the piston 4. This results in a gradual increase in the buffering force provided by the guide sleeve 2, guide rod 3, and piston 4, ultimately reducing the vibration generated by the hydrogen compressor and achieving better shock absorption.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0069] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
