Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and in particular to a marine air-cooled air compressor. Background Technology

[0002] In marine systems, air-cooled air compressors are the core compressed air generating equipment. Their essential function is to compress low-pressure air from the atmosphere into high-pressure air with a certain pressure and capacity, providing a "power source" or "control air source" for many key systems and equipment on the ship. In recent years, air-cooled air compressors have gradually become the mainstream choice for marine applications due to their simple structure, convenient maintenance, and strong adaptability.

[0003] Existing marine air-cooled compressors mainly consist of a casing, a main compressor, a drive motor for compressing gas, an air-cooling mechanism, a filtration mechanism, an oil-gas separation mechanism, a protective mechanism, and a control mechanism. However, current air-cooled air compressors still have significant shortcomings under typical harsh marine conditions such as high temperature, high humidity, and high salt spray. Currently, marine air-cooled compressors mainly employ two heat dissipation methods: first, increasing the area of ​​the heat sink to improve heat dissipation efficiency, but this increases the size and weight of the equipment, which is not conducive to the optimal utilization of ship space; second, increasing the fan speed or number to enhance cooling, but this leads to increased noise levels and energy consumption.

[0004] In view of the above-mentioned related technologies, in order to further improve the heat dissipation efficiency of the compressor host, the inventors believe that it is necessary to provide a marine air-cooled air compressor. Summary of the Invention

[0005] In order to effectively improve the heat dissipation efficiency of the compressor host, this application provides a marine air-cooled air compressor.

[0006] This application provides a marine air-cooled air compressor, which adopts the following technical solution:

[0007] A marine air-cooled air compressor includes a housing, a compressor main unit, and an air-cooling heat dissipation mechanism. The air-cooling heat dissipation mechanism includes a cooler installed at the top of the housing, a flow guide installed at the bottom of the cooler, heat dissipation blades arranged in the flow guide, and a heat dissipation motor installed at the bottom of the flow guide and used to drive the heat dissipation blades to rotate. The outer periphery of the heat dissipation blades is also provided with an air guide assembly.

[0008] The air guide assembly includes a rotating base, movable blades, and a rotary drive component for driving the rotating base to rotate. The movable blades are hinged to the rotating base. The inner wall of the air guide shroud is provided with an annular adjustment rail corresponding to the position of the movable blades. The end of the movable blades is also hinged to a roller, which is slidably connected to the annular adjustment rail.

[0009] By applying the above technical solution, when ambient gas is compressed into high-temperature gas by the compressor and enters the cooler through pipes, the cooling motor drives the cooling blades to rotate, forming a main airflow (which can be considered a forward airflow). Simultaneously, the rotating drive component drives the rotating base of the air guide assembly to rotate, causing the movable blades mounted on the base to deflect at an angle under the constraint of the annular adjusting rail and rollers, thereby guiding the generation of a coordinated counter-current airflow. The two airflows collide and merge within the air guide shroud, ultimately converging into a concentrated axial airflow. This axial airflow, on the one hand, enhances the cooling effect of the cooler upwards, and on the other hand, is discharged downwards to provide auxiliary cooling for the compressor casing, thus effectively improving the cooling efficiency of the compressor.

[0010] Optionally, the air guide shroud is provided with a mounting bracket for mounting the rotary drive component. The rotary drive component includes a main gear fixed to the output shaft of the cooling motor, a gear ring disposed inside the rotating base, and a transmission gear fixed to the bottom of the air guide shroud. The main gear meshes with the gear ring through the transmission gear to drive the rotating base to rotate.

[0011] By adopting the above technical solution, the specific structure of the rotary drive component is disclosed. Utilizing the meshing transmission of the main gear, transmission gear, and gear ring, the power of the cooling motor can be transmitted to the rotating base, causing the rotating base to rotate, which in turn drives the movable blades to rotate. This allows for adjustment of the airflow direction and range of the air-cooled cooling mechanism, effectively improving the heat dissipation efficiency of the air-cooled air compressor.

[0012] Optionally, the inner wall of the air guide shroud is provided with a guide groove with a shark gill-like structure, and the extension direction of the guide groove is tangential to the airflow direction generated by the rotation of the heat dissipation blades.

[0013] By adopting the above technical solution, the groove direction is tangent to the airflow direction, which does not block the airflow generated by the rotation of the heat dissipation blades, but guides the boundary layer airflow to pass smoothly. This can effectively suppress the lateral secondary flow, break the large-sized, energy-consuming vortex into small-sized vortex, greatly reduce the wall friction resistance, and since turbulence is the main noise source, reducing the separation of vortex and flow can reduce the noise generated by airflow.

[0014] Optionally, the annular adjustment rail has at least three positioning positions, each positioning position including a plurality of limiting grooves spaced circumferentially along the inner sidewall of the annular adjustment rail, the locking grooves being arranged in a stepped manner, and the limiting grooves being used to limit the rotation angle of the movable blade.

[0015] By adopting the above technical solution, the annular adjustment rail is equipped with at least three positioning positions and multiple limiting grooves distributed at intervals along the circumference, which can limit the rotation angle of the movable blades, allowing the movable blades to be positioned at different angles, thereby flexibly adjusting the airflow direction and air volume, and further improving the heat dissipation efficiency of the air-cooled heat dissipation mechanism.

[0016] Optionally, the outlet of the air guide shroud is provided with an airflow guide net, and the airflow guide net is oriented towards the compressor housing; the outer periphery of the airflow guide net is provided with a plurality of mounting ears, the mounting ears are provided with a first threaded hole, the air guide shroud is provided with a second threaded hole corresponding to the first threaded hole, and mounting studs are installed on the mounting ears in the first threaded hole and the second threaded hole.

[0017] By adopting the above technical solution, an airflow guide net is set at the outlet of the air guide shroud to guide the airflow to the compressor housing, which can effectively guide the cooling airflow to the compressor and enhance the heat dissipation effect on the compressor. The airflow guide net is installed with the air guide shroud through mounting ears, first threaded holes, second threaded holes and mounting studs, which facilitates the installation and disassembly of the airflow guide net and is convenient for maintenance and replacement.

[0018] Optionally, the blades of the airflow guide net are inclined relative to the airflow plane so that the outflowing airflow is directed to the outer surface of the compressor housing.

[0019] By adopting the above technical solution, the cooling airflow is transformed from disordered diffusion to precise directional delivery. This concentrates and controls the airflow to impact the compressor housing surface, greatly increasing the effective heat dissipation area and the convective heat transfer efficiency between the airflow and the housing. It also avoids energy loss caused by disordered turbulence within the housing, thereby achieving precise and efficient cooling of the core components.

[0020] Optionally, it also includes a shock-absorbing mechanism disposed at the bottom of the housing; the shock-absorbing mechanism includes a shock-absorbing base installed at the bottom of the housing and shock-absorbing pads disposed at the four corners of the bottom of the shock-absorbing base; the four sides of the shock-absorbing base are also provided with horizontal buffers, the other end of the horizontal buffers being connected to the inner wall of the housing; the horizontal buffers include a sleeve and a disc spring assembly disposed within the sleeve.

[0021] By adopting the above technical solutions, the vibration damping pad can buffer the vertical vibration of the marine air-cooled air compressor, and the disc spring assembly in the horizontal damper can buffer the horizontal vibration, thereby reducing the vibration during equipment operation, reducing damage to internal components, and improving the stability and service life of the equipment.

[0022] Optionally, the top of the shock-absorbing base is further provided with an angle adjustment mechanism for adjusting the installation angle of the drive motor. The angle adjustment mechanism includes an adjustment seat hinged to the shock-absorbing base, an adjustment bracket provided on the shock-absorbing base, and an adjustment cylinder with one end hinged to the adjustment bracket and the other end hinged to the adjustment seat; the number of adjustment cylinders is at least two sets.

[0023] By adopting the above technical solution, the angle adjustment mechanism's adjustment seat, adjustment bracket, and at least two sets of adjustment cylinders can adjust the angle of the shock-absorbing base, thereby adjusting the installation angle of the drive motor and thus adjusting the operating status of the compressor host.

[0024] Optionally, a vertical buffer is also installed between the adjusting seat and the shock-absorbing base. The vertical buffer includes a vertical buffer rod fixed to the shock-absorbing base, two sets of limiting discs sleeved on the vertical buffer rod, a buffer spring sleeved on the vertical buffer rod and abutting between the two sets of limiting discs, and a locking nut installed at the end of the vertical buffer rod. The vertical buffer rod passes through the adjusting seat; one of the limiting discs abuts the top of the adjusting seat.

[0025] By adopting the above technical solution, the vertical buffer structure forms a key local elastic support point between the adjustment seat and the damping base. Working in conjunction with the horizontal buffer, it upgrades the single planar damping into a multi-dimensional damping system that can cope with complex spatial force systems (such as ship pitching and rolling), greatly improving the stability and reliability of the equipment under harsh sea conditions, while also improving the stability after the drive motor angle is adjusted.

[0026] Optionally, the top of the housing is also provided with a removable access door, and the access door has ventilation mesh holes corresponding to the location of the cooler.

[0027] By adopting the above technical solution, a detachable inspection door is provided to facilitate the inspection and maintenance of the components inside the housing. Ventilation mesh is provided at the location of the cooler corresponding to the inspection door to ensure ventilation and heat dissipation of the cooler and improve the heat dissipation efficiency of the air-cooled heat dissipation mechanism for the compressor host.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] A marine air-cooled compressor compresses ambient gas into high-temperature gas and then delivers it to a cooler. A cooling motor drives blades to form a forward airflow, while a rotating drive component deflects the movable blades in the air guide assembly to generate a reverse airflow. The two airflows collide and merge within the air guide shroud to form a concentrated axial airflow, which enhances the cooling of the cooler upwards and is discharged downwards to assist in cooling the compressor housing, effectively improving the cooling efficiency of the compressor.

[0030] By creating shark gill-like grooves on the inner wall of the deflector, with the direction tangential to the airflow vortex, the boundary layer airflow can be smoothly guided, the lateral secondary flow can be suppressed, and large eddies can be broken into small-scale eddies, effectively reducing wall friction resistance and airflow noise.

[0031] By setting an airflow guide net at the outlet of the air shroud, the airflow is directed to the compressor housing, which can effectively guide the cooling airflow to the compressor and enhance the heat dissipation effect on the compressor. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a marine air-cooled air compressor. (Refer to...) Figure 1A marine air-cooled air compressor includes a housing 1, a compressor main unit 2, an air-cooling heat dissipation mechanism 3, a shock absorption mechanism 5, and an angle adjustment mechanism 6. The air-cooling heat dissipation mechanism 3, arranged in the housing 1, can effectively dissipate heat from the compressor main unit 2. The shock absorption mechanism 5 and the angle adjustment mechanism 6 reduce the vibration of the compressor main unit 2 during operation, improve the stability and adaptability of the equipment, and further enhance the heat dissipation efficiency of the compressor main unit 2 compared with the prior art.

[0040] Reference Figure 2 The air-cooled heat dissipation mechanism 3 includes a cooler 31 installed at the top of the housing 1, a guide shroud 32 installed at the bottom of the cooler 31, heat dissipation blades 33 arranged inside the guide shroud 32, and a heat dissipation motor 34 installed at the bottom of the guide shroud 32 for driving the heat dissipation blades 33 to rotate. An air guide assembly 4 is also provided on the outer periphery of the heat dissipation blades 33. The heat dissipation blades 33 have four blades, and the guide shroud 32 is cylindrical in shape. When the compressor 2 is working, the ambient gas is compressed by the compressor 2 to form high-temperature gas, which enters the cooler 31 through a pipe. The heat dissipation motor 34 drives the heat dissipation blades 33 to rotate, forming a main airflow (which can be considered a forward airflow). In this embodiment, the cooler 31 is a plate cooler 31.

[0041] Reference Figure 2 The air guide assembly 4 includes a rotating base 41, movable blades 42, and a rotary drive 43 that drives the rotating base 41 to rotate. The movable blades 42 are hinged to the rotating base 41. An annular adjusting rail 321 is provided on the inner wall of the air guide shroud 32 corresponding to the position of the movable blades 42. A roller 421 is also hinged to the end of the movable blades 42, and the roller 421 is slidably connected to the annular adjusting rail 321. The movable blades 42 are also four-bladed, and the air guide shroud 32 is provided with a mounting bracket for mounting the rotary drive 43. The rotary drive 43 drives the rotating base 41 of the air guide assembly 4 to rotate, causing the movable blades 42 mounted on the base to deflect at an angle under the constraint of the annular adjusting rail 321 and the roller 421, thereby guiding a coordinated counter-current airflow. The two airflows collide and merge within the air guide shroud 32, ultimately converging into a concentrated axial airflow. The axial airflow enhances the heat dissipation effect of the cooler 31 upwards on the one hand, and is discharged downwards on the other hand to assist in cooling the casing of the compressor 2, thereby effectively improving the heat dissipation efficiency of the compressor 2.

[0042] Reference Figure 2The air deflector 32 is provided with a mounting bracket 325 for mounting the rotary drive component 43. The rotary drive component 43 includes a main gear 431 fixed to the output shaft of the cooling motor 34, a gear ring 432 located inside the rotating base 41, and a transmission gear 434 fixed to the bottom of the air deflector 32. The main gear 431 meshes with the gear ring 432 through the transmission gear 434 to drive the rotating base 41 to rotate.

[0043] Reference Figure 2 The inner wall of the flow guide shroud 32 is provided with a flow guide groove 322 with a shark gill-like structure. The extension direction of the flow guide groove 322 is tangential to the airflow direction generated by the rotation of the heat dissipation blades 33. This can smoothly guide the boundary layer airflow, suppress the lateral secondary flow, and break the large eddy into small-scale eddy, effectively reducing wall friction resistance and airflow noise.

[0044] Reference Figure 2 The annular adjusting rail 321 is provided with at least three positioning positions. Each positioning position includes multiple limiting grooves 3211 spaced circumferentially along the inner wall of the annular adjusting rail 321. The locking grooves are arranged in a stepped manner, and the limiting grooves 3211 are used to limit the rotation angle of the movable blade 42. By adjusting the rotation angle of the movable blade 42, the direction and intensity of the airflow can be adjusted according to different operating conditions to meet different heat dissipation requirements.

[0045] Reference Figure 2 An airflow guide net 323 is provided at the outlet of the airflow guide shroud 32, and the airflow guide net 323 is oriented towards the outer casing of the compressor unit 2. The blades of the airflow guide net 323 are inclined relative to the airflow plane so that the airflow is directed to the surface of the compressor unit 2's outer casing. The inclined arrangement of the blades of the airflow guide net 323 relative to the airflow plane further guides the airflow, allowing it to be more precisely directed towards the compressor unit 2, thus improving heat dissipation.

[0046] Reference Figure 2 The airflow guide net 323 has multiple mounting ears 3231 on its outer periphery. Each mounting ear 3231 has a first threaded hole 32311, and the airflow shroud 32 has a second threaded hole 324 corresponding to the first threaded hole 32311. Mounting studs 32312 are installed on the mounting ears 3231 through the first threaded hole 32311 and the second threaded hole 324. This installation method facilitates the installation and removal of the airflow guide net 323, and makes maintenance and cleaning easier.

[0047] Reference Figure 3 The shock absorption mechanism 5 includes a shock absorption base 51 installed at the bottom of the housing 1 and shock absorption pads 52 located at the four corners of the bottom of the shock absorption base 51. The shock absorption pads 52 can buffer the vertical vibration of the marine air-cooled air compressor.

[0048] Reference Figure 4 The shock-absorbing base 51 is also provided with horizontal buffers 511 on its four sides, and the other end of the horizontal buffers 511 is connected to the inner wall of the housing 1. The horizontal buffers 511 include a sleeve 5111 and a disc spring assembly 5112 disposed in the sleeve 5111. The disc spring assembly 5112 can absorb vibration energy in the horizontal direction, further improving the shock absorption effect.

[0049] Reference Figure 3 and Figure 5 The top of the shock-absorbing base 51 is also provided with an angle adjustment mechanism 6 for adjusting the installation angle of the drive motor; the angle adjustment mechanism 6 includes an adjustment seat 61 hinged to the shock-absorbing base 51, an adjustment bracket 62 provided on the shock-absorbing base 51, and an adjustment cylinder 63 with one end hinged to the adjustment bracket 62 and the other end hinged to the adjustment seat 61; the number of adjustment cylinders 63 is at least two sets. In this embodiment, the number of adjustment cylinders 63 is two sets.

[0050] Reference Figure 3 A vertical buffer 64 is also installed between the adjusting seat 61 and the damping base 51. The vertical buffer 64 includes a vertical buffer rod 641 fixed to the damping base 51, two sets of limiting discs 642 sleeved on the vertical buffer rod 641, a buffer spring 643 sleeved on the vertical buffer rod 641 and abutting between the two sets of limiting discs 642, and a locking nut 644 installed at the end of the vertical buffer rod 641. The vertical buffer rod 641 passes through the adjusting seat 61; one limiting disc 642 abuts against the top of the adjusting seat 61. Through the coordinated work of the vertical buffer 64 structure and the horizontal buffer 511, the single planar damping is upgraded into a multi-dimensional damping system that can cope with complex spatial force systems (such as ship pitching and rolling), which greatly improves the stability and reliability of the equipment under harsh sea conditions, and at the same time improves the stability after the drive motor angle is adjusted.

[0051] Reference Figure 1 The top of the housing 1 is also provided with a removable maintenance door 11, and the maintenance door 11 is provided with ventilation mesh 12 corresponding to the position of the cooler 31.

[0052] The implementation principle of a marine air-cooled air compressor according to an embodiment of this application is as follows: A marine air-cooled air compressor includes a housing 1, a compressor main unit 2, and an air-cooling heat dissipation mechanism 3. After the ambient gas is compressed into high-temperature gas, it is delivered to the cooler 31. The heat dissipation motor 34 drives the blades to form a forward airflow. At the same time, the rotating drive component 43 drives the movable blades 42 in the air guide assembly 4 to deflect, generating a reverse airflow. The two airflows collide and merge in the air guide shroud 32 to form a concentrated axial airflow, which enhances the heat dissipation of the cooler 31 upward and is discharged downward to assist in the cooling of the housing of the compressor main unit 2, effectively improving the heat dissipation efficiency of the compressor main unit 2.

[0053] Specifically, the combination of shark gill-like structure-shaped guide grooves 322 and airflow guide nets 323 effectively improves heat dissipation efficiency while reducing airflow resistance; the gear-driven rotary drive component 43 ensures stable operation of the air guide assembly 4; the positioning position of the annular adjustment rail 321 can adjust the angle of the movable blades 42 according to actual conditions to achieve precise control of airflow; at the same time, the setting of the shock absorption mechanism 5 and the angle adjustment mechanism 6 reduces the vibration of the compressor host 2 during operation, improves the stability and adaptability of the equipment, and further improves the heat dissipation efficiency of the compressor host 2 compared with the existing technology.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
