DETAILED DESCRIPTION

[0032] Embodiment 1:

[0033] Please refer to Figure 1-Figure 6 The present embodiment is an air compressor unit 100 for powder tank truck transportation, which includes a mounting bracket 1, a driving module 2 mounted on the mounting bracket 1, an air compressor 3 connected to the output end of the driving module 2 for rotation transmission, an electric control box 4 connected to the driving module 2 for electrical signals, a first cooling module 5 connected to the internal cooling pipeline of the driving module 2 for circulation, a second cooling module 6 connected to the internal cooling pipeline of the air compressor 3 for circulation, an air filter 7 connected to the air inlet end of the air compressor 3, and a muffler 8 connected to the exhaust end of the air compressor 3. The first cooling module 5 and the second cooling module 6 are connected to the electric control box 4 for electrical signals.

[0034] The mounting bracket 1 comprises a first mounting layer 11 and a second mounting layer 12 which are arranged vertically. A plurality of supporting connecting rods 13 are arranged between the first mounting layer 11 and the second mounting layer 12, and the first mounting layer 11 is mounted on the second mounting layer 12 through the supporting connecting rods 13.

[0035] In order to improve the overall structural compactness and stability of the air compressor unit and reduce the space occupation, in this embodiment, the drive module 2 and the air compressor 3 are arranged on the second installation layer 12, and the electric control box 4, the first cooling module 5, the second cooling module 6 and the air filter 7 are arranged on the first installation layer 11. The double-layer structure design of the mounting bracket 1 is used to improve the space utilization rate, reduce the space occupation of the air compressor unit, and make it more convenient to implement the overall installation, maintenance and replacement of the air compressor unit. In addition, the heavier drive module 2 and the air compressor 3 are arranged on the second installation layer 12 at the bottom. When the drive module 2 and the air compressor 3 are in operation, the large shaking of the mounting bracket 1 can be effectively slowed down, thereby helping to improve the stability of the overall structure of the air compressor unit.

[0036] The drive module 2 includes a motor housing and a motor drive body arranged inside the motor housing. The motor housing adopts an integrated design of heat dissipation and protection. The motor housing is provided with heat dissipation fins and a dustproof and waterproof sealing structure. A temperature sensor (not shown in the figure) connected to the electrical signal of the electric control box 4 is installed inside. The temperature sensor monitors the internal temperature of the drive module 2 in real time to guide the first cooling module 5 to perform temperature control. Since the working environment of the powder tanker is relatively harsh, such as a lot of dust, large humidity changes, strong vibration, etc., the integrated motor housing structure design can effectively protect the motor drive body parts and transmission parts inside the motor housing, and extend the service life of the drive module 2. The electric control box 4 controls the first cooling module 5 to adjust the cooling efficiency according to the temperature sensor. Once an abnormal temperature increase is detected, the enhanced cooling measures will be started in time, and the sealing structure can effectively prevent dust and moisture from entering the motor, protect the normal operation of the motor, and extend the service life of the motor.

[0037] In this embodiment, the drive module 2 is an integrated drive assembly integrating a motor and a gearbox. In other embodiments, the drive module 2 may also only use a motor. The motor is a variable frequency motor, such as an asynchronous motor, a permanent magnet synchronous motor, a switched reluctance motor, a synchronous reluctance motor or a brushless DC motor, etc., and factors such as energy efficiency, reliability, cost and application environment can be comprehensively considered when selecting. The motor described in this embodiment is preferably an efficient permanent magnet synchronous motor, which has the advantages of high efficiency, high power density, high torque density, fast response, low noise and low vibration, wide speed regulation range, high reliability, energy saving and environmental protection, and precise control. In this embodiment, an integrated drive assembly integrating a motor and a gearbox is used, and the motor itself is small in size and weight, which helps to save energy during transportation with the vehicle.

[0038] The rotary output end of the drive module 2 and the rotary input end of the air compressor 3 are arranged horizontally and collinearly, and are connected together through a transmission member 40 to realize rotary transmission. Through this structural design, the transmission structure is reduced, the main vehicle gearbox and the power take-off shifting mechanism are eliminated, the energy loss caused by the transmission efficiency is reduced, the transmission efficiency is improved, and energy consumption is saved; at the same time, the use of a motor to drive the air compressor can also effectively reduce carbon emissions.

[0039] The driving module 2 is controlled by the electric control box 4, and the electric control box 4 is powered by the vehicle power supply. No additional external power supply is required, and it is suitable for on-vehicle operation in any occasion.

[0040] In this embodiment, the air inlet of the air compressor 3 is arranged at the end opposite to the connection end of the drive module 2, and the air filter 7 is arranged on the first installation layer 11 and is located directly above the air compressor 3, and is connected through the first pipeline 9. The main body of the first pipeline 9 is located outside the mounting bracket 1 and spans the height of two mounting layers. A rain cap 10 is provided at the exhaust port of the air filter 7 to prevent rainwater from entering the air filter 7 and then entering the air compressor 3. The exhaust port of the air compressor 3 is arranged on the upper side of the air compressor 3 and is connected to the muffler 8 through the second pipeline 20. In this embodiment, the muffler 8 is arranged on the second installation layer 12 of the mounting bracket 1 and is located next to the air compressor 3, which facilitates the layout of the second pipeline 20 and improves the overall structural compactness of the air compressor unit. Specifically, the muffler 8 is arranged on the second installation layer 12 in a lying state, making full use of the plane space of the second installation layer 12.

[0041] In this embodiment, a pressure sensor 21 for detecting the pressure in the second pipeline 20 is provided on the second pipeline 20, and the pressure sensor 21 is electrically connected to the electric control box 4. By providing the pressure sensor 21 on the exhaust pipeline of the air compressor 3, a real-time pressure signal is provided to monitor the operating state of the air compressor unit, thereby guiding the electric control box 4 to adjust the speed of the motor in the drive module 2 in real time, so that the input speed of the air compressor is adjusted within a certain range, ensuring that the dust discharge speed meets the set requirements and preventing the dust powder from clogging the pipeline; at the same time, it can also be applied to various different working conditions.

[0042] In this embodiment, the electric control box 4 is relatively small in size, a pair of mounting poles 14 are provided on the first mounting layer 11 of the mounting bracket 1, and the electric control box 4 is fixedly mounted on the mounting poles 14 in an upright state. The electric control box 4 is mounted on the first mounting layer 11 and is located above the driving module 2.

[0043] The upper shell of the driving module 2 is provided with a first inlet and a first outlet (not shown in the figure) connected to the internal cooling pipeline. The first cooling module 5 includes a pump 51 and a coolant tank 52. The internal cooling pipeline of the driving module 2 is connected to the pump 51 and the coolant tank 52 through pipelines to form a circulating cooling system. Specifically, the output end of the pump 51 is connected to the first inlet pipeline, the first outlet is connected to the return liquid pipeline of the coolant tank 52, and the liquid outlet of the coolant tank 52 is connected to the input end pipeline of the pump 51, thereby forming a circulating cooling system. The coolant in the coolant tank 52 is pumped into the cooling pipeline inside the driving module 2 by the pump 51, heat exchanged with the internal structure of the driving module 2 for cooling, and then returned to the coolant tank 52, so as to realize the cooling function of the internal temperature of the driving module 2. The temperature of the drive module 2 is controlled by setting the first cooling module 5, avoiding the use of the powder tanker main vehicle cooling mechanism. The independent cooling system increases the service life of the main vehicle cooling mechanism and the service life of the drive module 2, while reducing the failure rate of the main vehicle cooling mechanism.

[0044] The shell of the air compressor 3 is provided with a second inlet and a second outlet (not shown in the figure) connected to the internal cooling pipeline. The second cooling module 6 is an oil cooling device, the output port of the second cooling module 6 is connected to the second inlet pipeline, and the second outlet is connected to the input pipeline of the second cooling module 6, so that the second cooling module 6 and the internal cooling pipeline of the air compressor 3 form a circulating cooling system. By cooling the hydraulic oil inside the air compressor 3 through an external cooling module, the service life of the air compressor parts is greatly improved, and the service life of the air compressor lubricating oil is extended; maintenance costs are saved and the service life of the entire air compressor unit is extended.

[0045] In this embodiment, the air compressor 3 can be a screw air compressor, a piston air compressor, a vane air compressor or a centrifugal air compressor, and factors such as flow requirements, pressure requirements, energy efficiency requirements and maintenance costs should be comprehensively considered when selecting. In this embodiment, a screw air compressor is preferably used, which is light in weight, has low maintenance costs, and has a long service life, which can effectively reduce operating costs.

[0046] In this embodiment, a temperature sensor 30 for monitoring the internal operating temperature is provided on the air compressor 3. Specifically, the temperature sensor 30 is installed outside the screw bearing position of the air compressor, and by monitoring the temperature there, the second cooling module 6 is guided to perform excellent temperature control on the inside of the air compressor 3, so as to ensure that the air compressor works within a normal temperature range and improve the working conditions and service life of the air compressor 3.

[0047] In this embodiment, the electric control box 4 uses the on-board power supply of the electric vehicle to supply power to the drive module 2, drives the air compressor 3 to work, and adjusts the output power of the drive module 2 according to the pressure data collected by the pressure sensor 21 on the exhaust pipe of the air compressor 3; the electric control box 4 adjusts the output power of the pump 51 in the first cooling module 5 according to the temperature data collected by the temperature sensor in the drive module 2, adjusts the cooling efficiency of the drive module 2, and ensures that the drive module 2 always works within the set temperature range; the electric control box 4 also adjusts the cooling efficiency of the second cooling module 6 to the air compressor 3 according to the temperature data collected by the temperature sensor 30 on the air compressor 3, and ensures that the air compressor 3 always works within the set temperature range. Through the above design, the operation of the air compressor unit is more intelligent and reliable, and can be applied to more working conditions.
