Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic systems, in particular to a mobile garbage compression hydraulic power system. BACKGROUND

[0002] The mobile garbage compression equipment is a product matched with the hook arm garbage truck. The hook arm garbage truck transports the empty tank to the garbage compression station work station for garbage collection, and then repeatedly compresses the garbage through the hydraulic power system. The hydraulic power system generates heat during use, so it is usually necessary to use an air cooler to cool the hydraulic oil.

[0003] The patent document with the announcement number CN222950164U discloses an automatic temperature control system for a hydraulic station, which cools through a radiator assembly. The radiator pipes of the radiator assembly are respectively connected to the oil inlet and the oil outlet. However, in this automatic temperature control system, the hydraulic oil passes through all the radiator pipes regardless of the temperature, which can easily lead to a large flow resistance of the hydraulic oil, and in turn, a high power of the hydraulic pump in the hydraulic power system, thereby causing unnecessary energy waste. SUMMARY

[0004] Therefore, it is necessary to provide a mobile garbage compression hydraulic power system to solve the technical problem of energy waste caused by the current hydraulic cooling system.

[0005] The above-mentioned purpose is achieved by the following technical solutions:

[0006] A mobile garbage compactor hydraulic power system includes a hydraulic circuit, a heat sink, and a cooling fan. The hydraulic circuit provides hydraulic power to the mobile garbage compactor. The heat sink contains a first vertical pipe and a second vertical pipe, both extending vertically and horizontally. The first and second vertical pipes are distributed horizontally. The upper end of the second vertical pipe has an oil inlet, and the lower end of the first vertical pipe has an oil outlet. The oil inlet and outlet are connected to the hydraulic circuit. Multiple cooling pipes extending horizontally are connected between the first and second vertical pipes, and these cooling pipes are spaced apart vertically. The cooling fan generates airflow and directs it towards the cooling pipes. The first vertical pipe contains multiple first valves, and the second vertical pipe contains... There are multiple second valves. The first valve, cooling pipes, and second valves are arranged alternately in the vertical direction, and each corresponds to the position between two adjacent cooling pipes. When both the first valve and the second valve are fully open, a quick flow channel can be formed between the oil inlet and the oil outlet. This quick flow channel allows hydraulic oil to flow only through the first vertical pipe, the bottom cooling pipe, and the second vertical pipe. When both the first valve and the second valve are fully closed, a bent flow channel can be formed between the oil inlet and the oil outlet. This bent flow channel allows hydraulic oil to flow through the first vertical pipe, all the cooling pipes, and the second vertical pipe. When both the first valve and the second valve are in a state between being fully open and fully closed, both a quick flow channel and a bent flow channel can be formed between the oil inlet and the oil outlet.

[0007] Furthermore, the multiple cooling pipes are divided into a first cooling pipe, a second cooling pipe, and multiple capillary tube groups. The first cooling pipe is located at the top of the heat sink, the second cooling pipe is located at the bottom of the heat sink, and the multiple capillary tube groups are located between the first cooling pipe and the second cooling pipe and are distributed at intervals in the vertical direction. Each capillary tube group has multiple capillary cooling pipes extending in the horizontal direction. The two ends of the first cooling pipe, the second cooling pipe, and the capillary cooling pipes are respectively connected to the first vertical pipe and the second vertical pipe. The diameter of the first cooling pipe is the same as the diameter of the second cooling pipe, and both are larger than the diameter of the capillary cooling pipes.

[0008] Furthermore, the first valve and the second valve have the same structure. Both the first valve and the second valve include a liquid separator and a sealing ring. The axis of the liquid separator extends in the vertical direction. Each liquid separator is fixedly installed in the first vertical pipe or the second vertical pipe. The circumferential side wall of the liquid separator is provided with a communication port, which communicates with the interior of the first vertical pipe or the second vertical pipe. The sealing ring is coaxially installed inside the liquid separator. The sealing ring can slide up and down inside the liquid separator to block its corresponding communication port, thereby preventing the hydraulic oil from flowing downward in the first vertical pipe or the second vertical pipe, and thus guiding the hydraulic oil into the adjacent cooling pipe above it.

[0009] Furthermore, the bottom of the heat dissipation box is provided with a driving mechanism, which includes a driving plate, a first driving rod, a second driving rod, and a telescopic cylinder. The first driving rod is located in the first vertical pipe and is connected to the sealing rings of multiple first valves. The second driving rod is located in the second vertical pipe and is connected to the sealing rings of multiple second valves. The driving plate is located at the bottom of the heat dissipation box and is connected to both the first and second driving rods. The telescopic cylinder is driven by the driving plate. The telescopic cylinder drives the driving plate to move up and down by extending and retracting, thereby causing the first and second driving rods to move up and down synchronously, which in turn causes the sealing rings in the multiple first valves and multiple second valves to move up and down synchronously, thereby synchronously controlling the opening degree of the connecting ports on all the dispensing cylinders.

[0010] Furthermore, each of the sealing rings is slidably mounted on the first or second drive rod via an airbag. When all the connecting ports on the dispensing cylinders are open and the temperature of the hydraulic oil inside the heat sink rises, the airbag can extend in the vertical direction, thereby causing the sealing ring to slide upward and automatically reducing the degree of opening of the connecting ports on all the dispensing cylinders.

[0011] Furthermore, the connecting ports on the liquid separators of the multiple first valves are staggered in the vertical direction, and the connecting ports on the liquid separators of the multiple second valves are staggered in the vertical direction.

[0012] Furthermore, the sealing ring is semi-circular, and the arc surface of the sealing ring is used to seal the connection port. The sealing rings in the multiple first valves are aligned in the vertical direction, so that the connection ports on the liquid separators of the multiple first valves can be sealed simultaneously. The sealing rings in the multiple second valves are aligned in the vertical direction, so that the connection ports on the liquid separators of the multiple second valves can be sealed simultaneously.

[0013] Furthermore, each of the sealing rings can rotate in its corresponding separator. Above the heat sink, there is a first drive motor and a second drive motor. The first drive motor can drive the first drive rod to rotate, thereby causing the sealing rings in the multiple first valves to rotate synchronously. The second drive motor can drive the second drive rod to rotate, thereby causing the sealing rings in the multiple second valves to rotate synchronously. This allows the sealing rings in some of the first valves and some of the second valves to block the corresponding connecting ports, enabling the hydraulic oil to pass through only one capillary tube assembly.

[0014] Furthermore, the heat sink is provided with multiple windows, which allow the first cooling pipe, the second cooling pipe and the capillary cooling pipe to come into contact with the airflow generated by the cooling fan.

[0015] Furthermore, the outer surfaces of the first cooling pipe and the second cooling pipe are integrally formed with first heat dissipation fins, and the outer surface of the capillary cooling pipe is integrally formed with second heat dissipation fins. The first heat dissipation fins and the second heat dissipation fins are both spiral-shaped, and the pitch of the first heat dissipation fins is greater than the pitch of the second heat dissipation fins.

[0016] The beneficial effects of this invention are:

[0017] The mobile garbage compression hydraulic power system provided by this invention, firstly, can adjust the first and second valves to be fully open, fully closed, or in a state between fully open and fully closed, depending on the oil temperature of the hydraulic oil. This allows for the formation of a quick flow channel, a bend flow channel, or both between the inlet and outlet, thereby reducing the flow resistance of the hydraulic oil and thus lowering the energy consumption of the hydraulic power system (i.e., the mobile garbage compression hydraulic power system), while simultaneously cooling the hydraulic oil.

[0018] Secondly, when the hydraulic oil level in the initial cooling tank is low, the initial opening degree of the connecting ports on the liquid distribution cylinders of all the first and second valves can be reduced by synchronously controlling the first and second drive rods through the drive mechanism. This can adjust the amount of hydraulic oil entering the bend channel, thereby improving the cooling effect on the hydraulic oil and ensuring that the hydraulic power system can work normally.

[0019] Third, the first drive motor drives the first drive rod to rotate, which in turn drives the sealing rings in the multiple first valves to rotate synchronously. The second drive motor drives the second drive rod to rotate, which in turn drives the sealing rings in the multiple second valves to rotate synchronously. This allows each first valve and each second valve to open independently, ensuring that the hydraulic oil passes through only one capillary assembly. This guarantees the flow rate of the hydraulic oil in each capillary assembly, resulting in a better flushing effect. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] like Figures 1 to 12 As shown, an embodiment of the present invention provides a mobile garbage compression hydraulic power system (hereinafter referred to as the hydraulic power system), including a hydraulic circuit, a heat dissipation box 100, and a cooling fan 200. The hydraulic circuit is used to provide hydraulic power to the mobile garbage compression device 300.

[0038] The heat sink 100 has a first vertical pipe 101 and a second vertical pipe 102 inside. Both the first vertical pipe 101 and the second vertical pipe 102 extend in the vertical direction and are distributed in the horizontal direction. The upper end of the second vertical pipe 102 is provided with an oil inlet 103 and the lower end of the first vertical pipe 101 is provided with an oil outlet 104. Both the oil inlet 103 and the oil outlet 104 are connected to the hydraulic circuit. Multiple cooling pipes extending in the horizontal direction are connected between the first vertical pipe 101 and the second vertical pipe 102, and the multiple cooling pipes are distributed at intervals in the vertical direction. The cooling fan 200 is used to generate airflow and blow it onto each cooling pipe.

[0039] The first vertical pipe 101 is provided with a plurality of first valves 105, and the second vertical pipe 102 is provided with a plurality of second valves 106. The first valves 105, cooling pipes, and second valves 106 are alternately arranged in the vertical direction, and each corresponds to the position between two adjacent cooling pipes.

[0040] When both the first valve 105 and the second valve 106 are fully open, a quick flow channel can be formed between the oil inlet 103 and the oil outlet 104, which allows hydraulic oil to flow only through the first vertical pipe 101, the bottom cooling pipe, and the second vertical pipe 102; when both the first valve 105 and the second valve 106 are fully closed, a bent flow channel can be formed between the oil inlet 103 and the oil outlet 104, which allows hydraulic oil to flow through the first vertical pipe 101, all the cooling pipes, and the second vertical pipe 102; when both the first valve 105 and the second valve 106 are in a state between being fully open and fully closed, a quick flow channel and a bent flow channel can be formed simultaneously between the oil inlet 103 and the oil outlet 104.

[0041] The mobile garbage compactor hydraulic power system also includes structures such as a hydraulic pump, hydraulic cylinder, control valve, and filter, all of which are existing technologies. The hydraulic pump drives the flow of hydraulic oil; increased flow resistance of the hydraulic oil leads to increased energy consumption.

[0042] This allows the first valve 105 and the second valve 106 to be in a fully open, fully closed, or somewhere between fully open and fully closed state, depending on the temperature of the hydraulic oil. This creates a fast flow path, a bent flow path, or both between the inlet 103 and the outlet 104, reducing the flow resistance of the hydraulic oil and thus lowering the energy consumption of the hydraulic power system while simultaneously cooling the hydraulic oil.

[0043] More specifically, when the temperature of the hydraulic oil is lower than the minimum oil temperature setting, both the first valve 105 and the second valve 106 are fully opened. Under the action of gravity, the hydraulic oil enters from the inlet 103 and flows directly down along the second vertical pipe 102. Then, it flows out from the outlet 104 through the cooling pipe at the bottom. This reduces the flow resistance of the hydraulic oil, thereby reducing the energy consumption of the hydraulic power system (i.e., the energy consumption of the hydraulic pump).

[0044] When the temperature of the hydraulic oil exceeds the maximum set oil temperature, and both the first valve 105 and the second valve 106 are completely closed, the hydraulic oil enters from the inlet 103 and is blocked by the second valve 106 in the second vertical pipe 102. As a result, it flows along the uppermost cooling pipe into the first vertical pipe 101, and is then blocked by the first valve 105 in the first vertical pipe 101. As a result, it returns to the second vertical pipe 102 along the middle cooling pipe. This reciprocating flow, after passing through the first vertical pipe 101, all the cooling pipes, and the second vertical pipe 102, flows out from the outlet 104, which improves the cooling effect of the hydraulic oil.

[0045] When the hydraulic oil temperature is between the minimum and maximum setpoints, both the first valve 105 and the second valve 106 are in a state between fully open and fully closed. This allows a quick flow path and a zigzag flow path to be formed simultaneously between the inlet 103 and the outlet 104. A portion of the hydraulic oil passes through the quick flow path, while a portion passes through the zigzag flow path. This reduces the flow resistance of the hydraulic oil and cools it down.

[0046] Furthermore, the multiple cooling pipes are divided into a first cooling pipe 107, a second cooling pipe 108, and multiple capillary tube groups. The first cooling pipe 107 is located at the top of the heat sink 100, the second cooling pipe 108 is located at the bottom of the heat sink 100, and the multiple capillary tube groups are located between the first cooling pipe 107 and the second cooling pipe 108 and distributed in a vertical direction. Each capillary tube group has multiple capillary cooling pipes 109 extending in a horizontal direction. The two ends of the first cooling pipe 107, the second cooling pipe 108, and the capillary cooling pipes 109 are respectively connected to the first vertical pipe 101 and the second vertical pipe 102. In this embodiment, the multiple capillary cooling pipes 109 in each capillary tube group are distributed at intervals in a vertical direction. In other embodiments, the capillary cooling pipes 109 in each capillary tube group are distributed in a horizontal direction.

[0047] The diameter of the first cooling pipe 107 is the same as the diameter of the second cooling pipe 108, and both are larger than the diameter of the capillary cooling pipe 109. Since the second cooling pipe 108 is the bottommost cooling pipe and has a large diameter, the hydraulic oil can pass through it at a faster speed when flowing along the fast flow path, reducing the flow resistance. The small diameter of the capillary cooling pipe 109 increases the contact area between the hydraulic oil and the outside air, thereby improving the cooling effect on the hydraulic oil.

[0048] Furthermore, each cooling pipe is located between a first valve 105 and a second valve 106. The first valve 105 and the second valve 106 have the same structure. Both the first valve 105 and the second valve 106 include a distributor cylinder 111 and a sealing ring 115. The axis of the distributor cylinder 111 extends in the vertical direction. Each distributor cylinder 111 is fixedly installed in the first vertical pipe 101 or the second vertical pipe 102. The circumferential sidewall of the distributor cylinder 111 is provided with a connecting port 112, which communicates with the interior of the first vertical pipe 101 or the second vertical pipe 102. The sealing ring 115 is coaxially installed inside the distributor cylinder 111. The sealing ring 115 can slide up and down inside the distributor cylinder 111, thereby sealing its corresponding connecting port 112 to prevent the hydraulic oil from flowing downward in the first vertical pipe 101 or the second vertical pipe 102, and thus guiding the hydraulic oil into the adjacent cooling pipe above it. The first valve 105 and the second valve 106 have a simple structure and are easy to manufacture.

[0049] Furthermore, the bottom of the heat dissipation box 100 is provided with a driving mechanism, which includes a driving plate 117, a first driving rod 110, a second driving rod 116, and a telescopic cylinder 118; the first driving rod 110 is located in the first vertical pipe 101 and is connected to the sealing rings 115 of a plurality of first valves 105; the second driving rod 116 is located in the second vertical pipe 102 and is connected to the sealing rings 115 of a plurality of second valves 106; the driving plate 117 Located at the bottom of the heat sink 100 and connected to both the first drive rod 110 and the second drive rod 116; the telescopic cylinder 118 is connected to the drive plate 117 via transmission; the telescopic cylinder 118 drives the drive plate 117 to move up and down by telescopic movement, thereby causing the first drive rod 110 and the second drive rod 116 to move up and down synchronously, thereby causing the sealing rings 115 in the multiple first valves 105 and multiple second valves 106 to move up and down synchronously, thereby synchronously controlling the opening degree of the connecting ports 112 on all the dispensing cylinders 111.

[0050] A liquid level detector is installed in the radiator 100 to monitor the hydraulic oil level in the radiator 100 in real time. If the hydraulic oil level in the radiator 100 is low, it will result in insufficient circulating oil in the hydraulic power system, reducing the cooling effect and causing the oil temperature to rise.

[0051] When the hydraulic oil level in the initial heat sink 100 is low, the opening degree of the connecting port 112 on the liquid distribution cylinder 111 of all the first valves 105 and the second valves 106 can be reduced by synchronously controlling the first drive rod 110 and the second drive rod 116 through the drive mechanism. This increases the amount of hydraulic oil entering the bend flow channel, thereby improving the cooling effect on the hydraulic oil and ensuring that the hydraulic power system can work normally.

[0052] Furthermore, each of the sealing rings 115 is slidably mounted on the first drive rod 110 or the second drive rod 116 via an airbag 114. When the connecting ports 112 on all the dispensing cylinders 111 are open and the temperature of the hydraulic oil inside the heat sink 100 rises, the airbag 114 can extend in the vertical direction, thereby causing the sealing rings 115 to slide upward, thus automatically reducing the degree of opening of the connecting ports 112 on all the dispensing cylinders 111.

[0053] Specifically, the first drive rod 110 and the second drive rod 116 are each provided with a plurality of partitions 113, and the partitions 113 are provided in a one-to-one correspondence with the airbags 114. The bottom of the airbags 114 is fixedly mounted on the partitions 113, and the top of the airbags 114 is connected to the sealing rings 115.

[0054] During normal operation of the hydraulic power system, if the temperature of the hydraulic oil rises, the airbag 114 will be heated and elongated, causing the sealing ring 115 to slide upward, thereby automatically further reducing the opening degree of the connecting ports 112 on all the liquid separators 111, and thus allowing more hydraulic oil to flow along the bend flow channel, which can improve the cooling effect and accelerate the reduction of the hydraulic oil temperature.

[0055] Furthermore, the connecting ports 112 on the dispensing cylinders 111 of the multiple first valves 105 are staggered in the vertical direction, and the connecting ports 112 on the dispensing cylinders 111 of the multiple second valves 106 are also staggered in the vertical direction. This facilitates opening the connecting ports 112 on the dispensing cylinders 111 of the first valves 105 and the second valves 106 respectively.

[0056] Furthermore, the sealing ring 115 is semi-circular, and the connecting port 112 is rectangular. The arc surface of the sealing ring 115 is used to seal the connecting port 112. The sealing rings 115 in the multiple first valves 105 are aligned in the vertical direction, so that the connecting ports 112 on the dispensing cylinders 111 of the multiple first valves 105 can be sealed simultaneously. The sealing rings 115 in the multiple second valves 106 are aligned in the vertical direction, so that the connecting ports 112 on the dispensing cylinders 111 of the multiple second valves 106 can be sealed simultaneously.

[0057] Furthermore, each of the sealing rings 115 can rotate within its corresponding separator 111. Above the heat sink 100, a first drive motor 119 and a second drive motor 120 are also provided. The first drive motor 119 drives the first drive rod 110 to rotate, thereby causing the sealing rings 115 in the multiple first valves 105 to rotate synchronously. The second drive motor 120 drives the second drive rod 116 to rotate, thereby causing the sealing rings 115 in the multiple second valves 106 to rotate synchronously. Thus, the sealing rings 115 in some of the first valves 105 and some of the second valves 106 block the corresponding connecting ports 112, allowing the hydraulic oil to pass through only one capillary assembly. This ensures the flow rate of the hydraulic oil in each capillary assembly, resulting in a better flushing effect.

[0058] The output shaft of the first drive motor 119 extends into the first vertical tube 101 and slides up and down with the first drive rod 110 through splines and keyways. The output shaft of the second drive motor 120 extends into the second vertical tube 102 and slides up and down with the second drive rod 116 through splines and keyways.

[0059] The area of ​​the connecting opening 112 is smaller than the area of ​​the arc surface of the sealing ring 115. Since the sealing ring 115 is semi-circular, when the arc surface of the sealing ring 115 rotates to a position where it no longer blocks the connecting opening 112, the connecting opening 112 can be opened.

[0060] In this embodiment, the capillary assembly is provided in three groups, the first valve 105 is provided in two parts (upper and lower), and the second valve 106 is provided in two parts (upper and lower).

[0061] For example, by controlling the first valve 105 and the second valve 106 located at the top to be closed, while the first valve 105 and the second valve 106 located at the bottom are opened, hydraulic oil can be allowed to flow from the oil inlet 103, the first cooling pipe 107, the uppermost capillary group, and then into the second vertical pipe 102 and the second cooling pipe 108, and out of the oil outlet 104, thereby cleaning the uppermost capillary group.

[0062] Similarly, by controlling the upper second valve 106 to open and the upper first valve 105 to close (or open), while the lower second valve 106 is closed and the lower first valve 105 is open, hydraulic oil can flow out from the oil inlet 103, the second vertical pipe 102, the middle capillary group, and the first vertical pipe 101 to the oil outlet 104, thereby cleaning the middle capillary group.

[0063] By controlling the upper second valve 106 to close and the upper first valve 105 to open, while the lower second valve 106 is closed (or open) and the lower first valve 105 is closed, hydraulic oil can flow out from the oil inlet 103, the first cooling pipe 107, the first vertical pipe 101, the lowermost capillary assembly, and the second cooling pipe 108 through the oil outlet 104, thereby cleaning the lowermost capillary assembly.

[0064] Furthermore, the heat sink 100 is provided with multiple windows, which allow the first cooling pipe 107, the second cooling pipe 108, and the capillary cooling pipe 109 to come into contact with the airflow generated by the cooling fan 200. This ensures effective heat dissipation.

[0065] Furthermore, the outer surfaces of the first cooling pipe 107 and the second cooling pipe 108 are integrally formed with first heat dissipation fins 121, and the outer surface of the capillary cooling pipe 109 is integrally formed with second heat dissipation fins 122. Both the first heat dissipation fins 121 and the second heat dissipation fins 122 are spiral-shaped, and the pitch of the first heat dissipation fin 121 is greater than the pitch of the second heat dissipation fin 122. This increases the contact area between the first cooling pipe 107, the capillary pipe 109, and the second cooling pipe 108 and the airflow, thereby improving the cooling effect.

[0066] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows:

[0067] Before the hydraulic power system starts running, the hydraulic oil level in the radiator 100 is detected by a level detector. At this time, the oil temperature is within the normal range.

[0068] If the oil level is higher than the standard requirement, all first valves 105 and second valves 106 are initially fully opened, allowing hydraulic oil to flow through the quick-access channel. The hydraulic power system is then started, and the cooling fan 200 is turned on. As the hydraulic oil temperature rises, the air bladder 114 automatically extends, causing each sealing ring 115 to move upwards. The heated extension of the air bladder 114 causes the sealing rings 115 to slide upwards, automatically reducing the opening degree of the connecting ports 112 on all the distributor cylinders 111. This allows some hydraulic oil to flow along the bend in the channel, achieving automatic cooling of the hydraulic oil.

[0069] If the level detector detects that the hydraulic oil level is lower than the standard requirement, the drive mechanism synchronously controls the first drive rod 110 and the second drive rod 116 to move upward. This ensures that initially, all the connecting ports 112 on the distributor cylinders 111 of the first valve 105 and the second valve 106 are between fully open and fully closed. This allows some hydraulic oil to pass through the quick flow channel and the other part through the bend flow channel. By controlling the opening degree of the connecting ports 112 on all distributor cylinders 111, the amount of hydraulic oil entering the bend flow channel is controlled, thus ensuring the cooling effect of the hydraulic oil and ensuring the normal operation of the hydraulic power system. Then, the hydraulic power system starts running and the cooling fan 200 is turned on. As the temperature of the hydraulic oil rises, the air bladder 114 automatically extends, causing each sealing ring 115 to move upward. The heated extension of the air bladder 114 causes the sealing rings 115 to slide upward, thereby automatically further reducing the opening degree of the connecting ports 112 on all distributor cylinders 111, allowing more hydraulic oil to flow along the bend flow channel, achieving automatic cooling of the hydraulic oil.

[0070] After the hydraulic power system stops operating, if it is necessary to clean the radiator 100, firstly, drive plate 117 moves the first drive rod 110 and the second drive rod 116 upwards, closing all first valves 105 and second valves 106. Then, through the first drive motor 119 and the second drive motor 120, control the rotation of each sealing ring 115, so that the hydraulic oil passes through the three capillary tube groups respectively. This ensures the flow rate of the hydraulic oil in each capillary tube group, resulting in a better flushing effect.

[0071] 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.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.

Claims

1. A mobile garbage compression hydraulic power system, characterized in that, include: A hydraulic circuit, which provides hydraulic power to the mobile waste compactor; The heat sink has a first vertical pipe and a second vertical pipe inside. Both the first and second vertical pipes extend vertically and are distributed horizontally. The upper end of the second vertical pipe has an oil inlet and the lower end of the first vertical pipe has an oil outlet. The oil inlet and the oil outlet are connected to a hydraulic circuit. Multiple cooling pipes extending horizontally are connected between the first and second vertical pipes and are spaced apart vertically. A cooling fan, which generates airflow and directs it toward the cooling pipes; The first vertical pipe is equipped with multiple first valves, and the second vertical pipe is equipped with multiple second valves. The first valves, cooling pipes, and second valves are arranged alternately in the vertical direction, and each corresponds to the position between two adjacent cooling pipes. When both the first valve and the second valve are fully open, a quick flow channel can be formed between the oil inlet and the oil outlet, which allows the hydraulic oil to flow only through the first vertical pipe, the bottom cooling pipe, and the second vertical pipe. When both the first valve and the second valve are fully closed, a bent flow channel can be formed between the oil inlet and the oil outlet, which allows the hydraulic oil to flow through the first vertical pipe, all the cooling pipes, and the second vertical pipe. When both the first and second valves are in a state between fully open and fully closed, a fast flow channel and a bent flow channel can be simultaneously formed between the oil inlet and outlet. Multiple cooling pipes are divided into a first cooling pipe, a second cooling pipe, and multiple capillary tube groups. The first cooling pipe is located at the top of the heat sink, the second cooling pipe is located at the bottom of the heat sink, and multiple capillary tube groups are located between the first and second cooling pipes and are spaced apart in the vertical direction. Each capillary tube group has multiple capillary cooling tubes extending in the horizontal direction. The two ends of the first cooling pipe, the second cooling pipe, and the capillary cooling tubes are respectively connected to the first vertical pipe and the second vertical pipe. The diameter of the first cooling pipe is the same as that of the second cooling pipe, and both are larger than the diameter of the capillary cooling pipe. Each cooling pipe is located between a first valve and a second valve. The first and second valves have identical structures, each including a distributor and a sealing ring. The axis of the distributor extends vertically, and each distributor is fixedly installed in either the first or second vertical pipe. The circumferential sidewall of the distributor has a connecting port that communicates with the interior of the first or second vertical pipe. The sealing ring is coaxially installed inside the distributor and can slide up and down inside the distributor to seal its respective component. The heat sink has a corresponding connection port to prevent hydraulic oil from flowing downwards in the first or second vertical pipe, thereby guiding the hydraulic oil into the adjacent cooling pipe above it. The bottom of the heat sink is equipped with a drive mechanism, which includes a drive plate, a first drive rod, a second drive rod, and a telescopic cylinder. The first drive rod is located in the first vertical pipe and is connected to the sealing rings of multiple first valves. The second drive rod is located in the second vertical pipe and is connected to the sealing rings of multiple second valves. The drive plate is located at the bottom of the heat sink and is connected to both the first and second drive rods. The telescopic cylinder is drively connected to the drive plate.The telescopic cylinder moves the drive plate up and down by extending and retracting, thereby causing the first and second drive rods to move up and down synchronously. This, in turn, causes the sealing rings in multiple first and second valves to move up and down synchronously, thus synchronously controlling the opening degree of the connecting ports on all the dispensing cylinders. The connecting ports on the dispensing cylinders of the multiple first valves are staggered vertically, and the connecting ports on the dispensing cylinders of the multiple second valves are also staggered vertically. The sealing rings are semi-circular, and their arc surfaces are used to seal the connecting ports. The sealing rings in the multiple first valves are aligned vertically, thus simultaneously sealing the connecting ports on the dispensing cylinders of the multiple first valves.
