[0023] As shown in Figures 1 to 12 An embodiment of the present application provides a mobile garbage compression hydraulic power system (hereinafter referred to as a hydraulic power system), which comprises a hydraulic circuit, a heat dissipation box 100 and a heat dissipation fan 200. The hydraulic circuit is used to provide hydraulic power for a mobile garbage compression device 300.

[0024] The heat dissipation box 100 is internally provided with a first vertical pipe 101 and a second vertical pipe 102, both of which extend in the up-down direction, and the first vertical pipe 101 and the second vertical pipe 102 are distributed in the left-right 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. The oil inlet 103 and the oil outlet 104 are connected with the hydraulic circuit. A plurality of cooling pipes extending in the left-right direction are communicated between the first vertical pipe 101 and the second vertical pipe 102, and the plurality of cooling pipes are spaced apart in the up-down direction. The heat dissipation fan 200 is used to generate airflow and blow to each cooling pipe.

[0025] A plurality of first valves 105 are arranged in the first vertical pipe 101, and a plurality of second valves 106 are arranged in the second vertical pipe 102. The first valves 105, the cooling pipes and the second valves 106 are alternately arranged in the up-down direction, and each corresponds to the position between adjacent two cooling pipes.

[0026] When the first valve 105 and the second valve 106 are both fully opened, a shortcut flow channel is formed between the oil inlet 103 and the oil outlet 104, which makes the hydraulic oil flow only through the first vertical pipe 101, the bottommost cooling pipe and the second vertical pipe 102; when the first valve 105 and the second valve 106 are both fully closed, a bending flow channel is formed between the oil inlet 103 and the oil outlet 104, which makes the hydraulic oil flow through the first vertical pipe 101, all the cooling pipes and the second vertical pipe 102; when the first valve 105 and the second valve 106 are both between fully opened and fully closed, a shortcut flow channel and a bending flow channel are formed between the oil inlet 103 and the oil outlet 104 at the same time.

[0027] The mobile garbage compression hydraulic power system further comprises a hydraulic pump, a hydraulic cylinder, a control valve and a filter and the like structures, which all belong to the prior art. Among them, the hydraulic pump is used to drive the flow of hydraulic oil, and the increase of the flow resistance of the hydraulic oil will synchronously cause the increase of its energy consumption.

[0028] In this way, according to the oil temperature of the hydraulic oil, the first valve 105 and the second valve 106 can be in a fully opened, fully closed or between fully opened and fully closed state, so that a shortcut flow channel, a bending flow channel or both a shortcut flow channel and a bending flow channel can be formed between the oil inlet 103 and the oil outlet 104, the flow resistance of the hydraulic oil is reduced, thereby reducing the energy consumption of the hydraulic power system, and the cooling of the hydraulic oil is realized at the same time.

[0029] More specifically, when the temperature of the hydraulic oil is lower than the minimum oil temperature setting value, the first valve 105 and the second valve 106 are both fully opened, under the action of gravity, the hydraulic oil entering from the oil inlet 103 directly flows downward along the second vertical pipe 102, and then flows out from the oil outlet 104 through the bottommost cooling pipe, which can reduce 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).

[0030] When the temperature of the hydraulic oil exceeds the maximum oil temperature setting value, the first valve 105 and the second valve 106 are both fully closed, the hydraulic oil entering from the oil inlet 103 is blocked by the second valve 106 in the second vertical pipe 102, so as to flow along the uppermost cooling pipe into the first vertical pipe 101, and then is blocked by the first valve 105 in the first vertical pipe 101, so as to return to the second vertical pipe 102 along the middle cooling pipe, which is a reciprocating bending flow, so that the hydraulic oil flows through the first vertical pipe 101, all the cooling pipes and the second vertical pipe 102 and then flows out from the oil outlet 104, which can improve the cooling effect of the hydraulic oil.

[0031] When the temperature of the hydraulic oil is between the minimum oil temperature set value and the maximum oil temperature set value, the first valve 105 and the second valve 106 are both in a state between fully open and fully closed, so that the shortcut flow channel and the bending flow channel can be simultaneously formed between the oil inlet 103 and the oil outlet 104, a part of the hydraulic oil passes through the shortcut flow channel, and a part of the hydraulic oil passes through the bending flow channel, so that the flow resistance of the hydraulic oil can be reduced, and the hydraulic oil can be cooled.

[0032] Further, the plurality of cooling pipelines are divided into a first cooling pipe 107, a second cooling pipe 108, and a plurality of capillary pipe groups. The first cooling pipe 107 is located at the top of the heat dissipation box 100, the second cooling pipe 108 is located at the bottom of the heat dissipation box 100, and the plurality of capillary pipe groups are located between the first cooling pipe 107 and the second cooling pipe 108 and are distributed in the up-down direction. Each capillary pipe group has a plurality of capillary cooling pipes 109 extending in the left-right direction. The two ends of the first cooling pipe 107, the second cooling pipe 108, and the capillary cooling pipe 109 are respectively communicated with the first vertical pipe 101 and the second vertical pipe 102. In this embodiment, the plurality of capillary cooling pipes 109 in each capillary pipe group are spaced apart in the up-down direction. In other embodiments, the capillary cooling pipes 109 in each capillary pipe group are distributed in the horizontal direction.

[0033] The diameter of the first cooling pipe 107 is consistent with the diameter of the second cooling pipe 108, and both are greater than the diameter of the capillary cooling pipe 109. Since the second cooling pipe 108 is the bottommost cooling pipeline, and the diameter of the second cooling pipe 108 is large, when the hydraulic oil flows along the shortcut flow channel, the hydraulic oil can pass through the second cooling pipe 108 at a faster speed, reducing the flow resistance of the hydraulic oil. The diameter of the capillary cooling pipe 109 is small, which can increase the contact area of the hydraulic oil with the external air, thereby improving the cooling effect of the hydraulic oil.

[0034] Further, each cooling pipeline 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. The first valve 105 and the second valve 106 each include a distribution cylinder 111 and a blocking ring 115. The axis of the distribution cylinder 111 extends in the up-down direction, and each distribution cylinder 111 is fixedly arranged in the first vertical pipe 101 or the second vertical pipe 102. The circumferential side wall of the distribution cylinder 111 is provided with a communication port 112, which is communicated with the inside of the first vertical pipe 101 or the second vertical pipe 102. The blocking ring 115 is coaxially arranged in the inside of the distribution cylinder 111. The blocking ring 115 can slide up and down in the inside of the distribution cylinder 111, thereby blocking the respective corresponding communication port 112 to hinder the downward flow of the hydraulic oil in the first vertical pipe 101 or the second vertical pipe 102, and further guiding the hydraulic oil into the adjacent cooling pipeline located above. The structure of the first valve 105 and the second valve 106 is simple and convenient to process.

[0035] Further, the bottom of the heat dissipation box 100 is provided with a driving mechanism, the driving mechanism 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 the first driving rod 110 is connected with the blocking ring 115 of the plurality of first valves 105; the second driving rod 116 is located in the second vertical pipe 102, and the second driving rod 116 is connected with the blocking ring 115 of the plurality of second valves 106; the driving plate 117 is located at the bottom of the heat dissipation box 100 and is connected with the first driving rod 110 and the second driving rod 116 at the same time; the telescopic cylinder 118 is in transmission connection with the driving plate 117; the telescopic cylinder 118 drives the driving plate 117 to move up and down through the telescopic belt, so that the first driving rod 110 and the second driving rod 116 move up and down synchronously, and then the blocking ring 115 in the plurality of first valves 105 and the plurality of second valves 106 moves up and down synchronously, thereby synchronously controlling the opening degree of the communication port 112 on all the distribution cylinders 111.

[0036] The heat dissipation box 100 is provided with a liquid level detector, which monitors the oil level of the hydraulic oil in the heat dissipation box 100 in real time. For the hydraulic oil in the vehicle hydraulic system, if the oil level of the hydraulic oil in the heat dissipation box 100 is low, the circulating oil amount in the hydraulic power system will be insufficient, the cooling effect will be reduced, and the oil temperature will rise.

[0037] In this way, when the initial oil level of the hydraulic oil in the heat dissipation box 100 is low, the opening degree of the communication port 112 on all the distribution cylinders 111 of the first valve 105 and the second valve 106 is reduced by synchronously controlling the first driving rod 110 and the second driving rod 116 through the driving mechanism, the amount of hydraulic oil entering the bent flow channel is increased, and the cooling effect of the hydraulic oil is improved, thereby ensuring that the hydraulic power system can work normally.

[0038] Further, each of the blocking rings 115 is slidably arranged on the first driving rod 110 or the second driving rod 116 through the air bag 114, when the communication port 112 on all the distribution cylinders 111 is opened and the temperature of the hydraulic oil in the heat dissipation box 100 rises, the air bag 114 can be elongated in the upward and downward directions to make the blocking ring 115 slide upward, thereby automatically reducing the opening degree of the communication port 112 on all the distribution cylinders 111.

[0039] Specifically, a plurality of partitions 113 are arranged on the first driving rod 110 and the second driving rod 116, the partitions 113 are arranged one by one corresponding to the air bags 114, the bottom of the air bag 114 is fixedly arranged on the partition 113, and the top of the air bag 114 is connected with the blocking ring 115.

[0040] In the normal working process of the hydraulic power system, if the temperature of the hydraulic oil rises, the air bag 114 will be heated and elongated, driving the blocking ring 115 to slide upward, thereby automatically further reducing the opening degree of the communication port 112 on all the distribution cylinders 111, and further making more hydraulic oil flow along the bent flow channel, so as to improve the cooling effect and accelerate the reduction of the temperature of the hydraulic oil.

[0041] Further, the communication ports 112 on the distribution cylinders 111 of the plurality of first valves 105 are arranged staggered in the up-down direction, and the communication ports 112 on the distribution cylinders 111 of the plurality of second valves 106 are arranged staggered in the up-down direction. In this way, it is convenient to open the communication ports 112 on the distribution cylinders 111 of the first valves 105 and the communication ports 112 on the distribution cylinders 111 of the second valves 106, respectively.

[0042] Further, the blocking ring 115 is semicircular, the communication port 112 is rectangular, the arc surface of the blocking ring 115 is used to block the communication port 112, the blocking rings 115 in the plurality of first valves 105 are aligned in the up-down direction, so as to be able to simultaneously block the communication ports 112 on the distribution cylinders 111 of the plurality of first valves 105, and the blocking rings 115 in the plurality of second valves 106 are aligned in the up-down direction, so as to be able to simultaneously block the communication ports 112 on the distribution cylinders 111 of the plurality of second valves 106.

[0043] Further, each of the blocking rings 115 can rotate in the corresponding distribution cylinder 111, and the upper part of the heat dissipation box 100 is further provided with a first driving motor 119 and a second driving motor 120, the first driving motor 119 can drive the first driving rod 110 to rotate, thereby driving the blocking rings 115 in the plurality of first valves 105 to rotate synchronously, and the second driving motor 120 can drive the second driving rod 116 to rotate, thereby driving the blocking rings 115 in the plurality of second valves 106 to rotate synchronously, so that the blocking rings 115 in part of the first valves 105 and part of the second valves 106 block the corresponding communication ports 112, so as to make the hydraulic oil only pass through one capillary group. In this way, the flow rate of the hydraulic oil in each capillary group can be ensured, so as to have a good flushing effect.

[0044] The output shaft of the first driving motor 119 extends into the first vertical pipe 101 and is in up-down sliding fit with the first driving rod 110 through the spline and the key groove, and the output shaft of the second driving motor 120 extends into the second vertical pipe 102 and is in up-down sliding fit with the second driving rod 116 through the spline and the key groove.

[0045] The area of the communication port 112 is smaller than the area of the arc surface of the blocking ring 115, and since the blocking ring 115 is semicircular, when the arc surface of the blocking ring 115 rotates to a position where it no longer blocks the communication port 112, the communication port 112 can be opened.

[0046] In the embodiment, three groups of capillary tubes are provided, the first valve 105 is provided with two upper and lower valves, and the second valve 106 is provided with two upper and lower valves.

[0047] For example, by controlling the upper first valve 105 and the upper second valve 106 to be closed, and the lower first valve 105 and the lower second valve 106 to be opened, the hydraulic oil can flow from the oil inlet 103, the first cooling pipe 107, the uppermost capillary tube group, then enter the second vertical pipe 102, the second cooling pipe 108, and then flow out from the oil outlet 104, so that the uppermost capillary tube group can be cleaned.

[0048] Similarly, by controlling the upper second valve 106 to be opened and the upper first valve 105 to be closed (or opened), and the lower second valve 106 to be closed and the lower first valve 105 to be opened, the hydraulic oil can flow from the oil inlet 103, the second vertical pipe 102, the middle capillary tube group, the first vertical pipe 101, and then flow out from the oil outlet 104, so that the middle capillary tube group can be cleaned.

[0049] By controlling the upper second valve 106 to be closed and the upper first valve 105 to be opened, and the lower second valve 106 to be closed (or opened) and the lower first valve 105 to be closed, the hydraulic oil can flow from the oil inlet 103, the first cooling pipe 107, the first vertical pipe 101, the lowermost capillary tube group, the second cooling pipe 108, and then flow out from the oil outlet 104, so that the lowermost capillary tube group can be cleaned.

[0050] Further, the heat dissipation box 100 is provided with a plurality of windows, the windows enable the first cooling pipe 107, the second cooling pipe 108 and the capillary cooling pipe 109 to contact the airflow generated by the heat dissipation fan 200. In this way, the heat dissipation effect can be ensured.

[0051] Further, the outer surfaces of the first cooling pipe 107 and the second cooling pipe 108 are integrally formed with first heat dissipation fins 121, the outer surface of the capillary cooling pipe 109 is integrally formed with second heat dissipation fins 122, the first heat dissipation fins 121 and the second heat dissipation fins 122 are in a spiral shape, and the pitch of the first heat dissipation fins 121 is greater than the pitch of the second heat dissipation fins 122. In this way, the contact area of the first cooling pipe 107, the capillary tube 109 and the second cooling pipe 108 with the airflow can be increased, and the cooling effect can be improved.

[0052] In combination with the above embodiment, the use principle and working process of the embodiment of the application are as follows: Before the hydraulic power system starts to operate, the hydraulic oil level in the heat dissipation box 100 is detected by the liquid level detector, and at this time, the oil temperature is in a normal range.

[0053] If the oil level is higher than the standard requirement, all the first valves 105 and the second valves 106 are fully opened initially, and the hydraulic oil flows through the shortcut flow channel. Then the hydraulic power system starts to run, and the cooling fan 200 is turned on. As the temperature of the hydraulic oil rises, the air bags 114 are automatically elongated, and the blocking rings 115 are moved upward. The elongation of the air bags 114 drives the blocking rings 115 to slide upward, thereby automatically reducing the opening degree of the communication ports 112 of all the distribution cylinders 111, and more hydraulic oil flows through the bending flow channel, so as to realize the automatic cooling of the hydraulic oil.

[0054] If the oil level detector detects that the oil level of the hydraulic oil is lower than the standard requirement, the first driving rod 110 and the second driving rod 116 are synchronously controlled to move upward by the driving mechanism, so that the communication ports 112 of all the first valves 105 and the second valves 106 on the distribution cylinders 111 are initially between the fully opened state and the fully closed state. A part of the hydraulic oil flows through the shortcut flow channel, and another part of the hydraulic oil flows through the bending flow channel. By controlling the opening degree of all the communication ports 112 of the distribution cylinders 111, the amount of the hydraulic oil entering the bending flow channel is controlled, so as to ensure the cooling effect of the hydraulic oil and ensure that the hydraulic power system can work normally. Then the hydraulic power system starts to run, and the cooling fan 200 is turned on. As the temperature of the hydraulic oil rises, the air bags 114 are automatically elongated, and the blocking rings 115 are moved upward. The elongation of the air bags 114 drives the blocking rings 115 to slide upward, thereby automatically further reducing the opening degree of the communication ports 112 of all the distribution cylinders 111, and more hydraulic oil flows through the bending flow channel, so as to realize the automatic cooling of the hydraulic oil.

[0055] After the hydraulic power system stops running, if the cooling tank 100 needs to be cleaned, the first driving rod 110 and the second driving rod 116 are moved upward by the driving plate 117, so that all the first valves 105 and the second valves 106 are closed. Then the first driving motor 119 and the second driving motor 120 are controlled to rotate the blocking rings 115, so that the hydraulic oil flows through the three capillary tube groups respectively. In this way, the flow rate of the hydraulic oil in each capillary tube group can be ensured, so as to have a good flushing effect.
