[0038] Hydraulic oil is transported inside the delivery pipeline 1. The flow of hydraulic oil inside the delivery pipeline 1 will generate heat. Coolant flows on the first delivery pipe 32 and the second delivery pipe 321 to cool the hydraulic oil inside the delivery pipe 1. The hydraulic oil flowing inside the delivery pipe 1 will drive the impeller 36 and the device thereon to rotate. Due to the action of the second rotating shaft 35 and the swing rod 37, the connecting rod 34 will reciprocate up and down, so that the reciprocating pump 33 operates and drives the coolant on the first delivery pipe 32 and the second delivery pipe 321 to circulate, thereby improving the cooling efficiency of the coolant inside the first delivery pipe 32 on the hydraulic oil inside the delivery pipe 1. If the hydraulic pressure of the hydraulic oil inside the delivery pipe 1 increases, its temperature will also increase accordingly. When the hydraulic pressure of the hydraulic oil inside the delivery pipe 1 is too large, its temperature will also be too high. The hydraulic oil inside the conveying pipeline 1 can push the pressure plate 23 to swing, and the torsion spring 24 will be compressed accordingly. The pressure plate 23 will drive the U-shaped guide rod 25 and the device thereon to move upward, so that the inclined surface 44 no longer supports the push rod 41, and the compressed first compression spring 43 will then recover and drive the blocking bar 42 and the device thereon to move in a direction away from the reciprocating pump 33, so that the blocking bar 42 is fully opened, thereby increasing the flow rate of the coolant per unit time, thereby further improving the cooling efficiency. When the hydraulic pressure of the hydraulic oil inside the conveying pipeline 1 decreases, the torsion spring 24 will then reset and drive the pressure plate 23 to reset, and the pressure plate 23 will drive the U-shaped guide rod 25 and the device thereon to reset, the inclined surface 44 will squeeze the push rod 41 and the device thereon to reset, and the first compression spring 43 will then be compressed and reset.

[0039] The top of the injection tube 52 is connected to other coolant supply ports, and one end of the drain tube 56 is connected to other coolant collection devices. When the device has been running for a period of time, it is necessary to replace the coolant in the first infusion tube 32. The guide cavity plate 53 and the device thereon are manually pushed to move in the direction close to the delivery pipeline 1 and maintained, and the first tension spring 54 will be compressed accordingly, so that the first infusion tube 32 and the second infusion tube 321 are aligned with the through hole on the guide cavity plate 53 away from the delivery pipeline 1, so that the used coolant in the first infusion tube 32 and the second infusion tube 321 can pass through the drain tube 56. The liquid pipe 56 is discharged to other coolant collection devices, and the new coolant can enter the guide cavity plate 53 through the injection pipe 52 and the supply pipe 55 and be injected into the first infusion pipe 32 and the second infusion pipe 321, so that the hydraulic oil inside the first infusion pipe 32 and the second infusion pipe 321 can be replaced to improve the cooling efficiency. When the coolant inside the first infusion pipe 32 and the second infusion pipe 321 is replaced, the guide cavity plate 53 is released, and the first tension spring 54 will be reset and drive the guide cavity plate 53 and the device thereon to reset. At this time, the coolant is no longer replaced.

[0040] Example 2

[0041] On the basis of Example 1, Fig. 9 As shown, it also includes a limiting component 6, which is used to replace manual operation to maintain the position of the guide cavity plate 53 and the device thereon, and is arranged on the conveying pipeline 1. The limiting component 6 includes a guide frame 61, a limiting plate 62, a connecting plate 63 and a limiting spring 64. One side of the outer wall of the conveying pipeline 1 is fixedly connected to the guide frame 61, and the limiting plate 62 is slidably connected to the guide frame 61. The top of the limiting plate 62 close to the guide support rod 51 is a symmetrical convex block structure, and the tops of the two convex blocks are inclined structures. The connecting plate 63 is fixedly connected to the guide cavity plate 53, and the connecting plate 63 is L-shaped. The connecting plate 63 contacts the limiting plate 62, and a limiting spring 64 is connected between the limiting plate 62 and the guide frame 61 to drive the limiting plate 62 to reset.

[0042] When the guide cavity plate 53 and the device thereon move toward the direction approaching the conveying pipeline 1, the limit plate 62 can clamp the connecting plate 63 through the cooperation of the limit plate 62 and the limit spring 64 to prevent the connecting plate 63 and the device thereon from resetting, thereby replacing the manual maintenance of the position of the guide cavity plate 53 and the device thereon by humans.

[0043] Example 3

[0044] On the basis of Example 2, Figure 10-11As shown, it also includes a reset component 7, which is arranged on the guide frame 61. The reset component 7 includes a movable bar 71, a second compression spring 72, a third compression spring 73, a lower pressure rod 74, a second tension spring 75, an inclined movable rod 76, a support frame 77, a fixed plate 78 and a push plate 79. The guide frame 61 is slidably connected with the movable bar 71, and a second compression spring 72 for driving the movable bar 71 and the device thereon to reset is connected between the movable bar 71 and the guide frame 61.

[0045] When the temperature of the hydraulic oil in the delivery pipeline 1 increases, the U-shaped guide rod 25 and the device thereon move upward due to the increase in the temperature of the hydraulic oil in the delivery pipeline 1, the open frame 77 will push the movable bar 71 to move in the direction close to the delivery pipeline 1, and the second compression spring 72 and the third compression spring 73 will be compressed accordingly, and the inclined movable rod 76 will squeeze the push plate 79 to swing. When the temperature of the hydraulic oil in the delivery pipeline 1 increases to a certain value, the open frame 77 and the device thereon will continue to move upward, and the open frame 77 will push the inclined movable rod 76 and the device thereon to move in the direction away from the delivery pipeline 1, and the second tension spring 75 will be stretched accordingly, and the downward pressure rod 74 can push the limit plate 62 to move downward, and the limit spring 64 will be compressed accordingly, and the third compression spring 73 will be reset and drive the connecting plate 63 and the device thereon to move to the other side of the limit plate 62, so that the through hole connecting the guide cavity plate 53 with the first infusion pipe 32 and the second infusion pipe 321 can be quickly replaced, so as to facilitate the replacement of the coolant in the first infusion pipe 32 and the second infusion pipe 321, avoiding the trouble of manual adjustment and replacement.
