The plurality of refrigeration pieces 48 fixedly installed in the inside of the air guide piece six 32 are controlled to work for a period of time, the refrigeration pieces 48 work to refrigerate, the airflow flowing in the inside of the air guide piece six 32 is cooled, and the effect of the hydraulic integrated module 2 on heat dissipation is further increased.

[0102] When the hydraulic integrated module 2 controls each hydraulic device in the paste filling template hydraulic support 1, high-pressure hydraulic oil flows in the rubber tube 8, and the sponge block 14 is arranged at the bottom of the connection part between the water outlet piece 6 and the connecting piece 7 and the connection part between the rubber tube 8 and the connecting piece 7.

[0103] If the connection part between the water outlet piece 6 and the connecting piece 7 or the connection part between the rubber tube 8 and the connecting piece 7 at the position of the sponge block 14 is broken and leaks, the sponge block 14 is arranged to absorb the leaked hydraulic oil, and the oil content in the sponge block 14 is increased; the thin film humidity sensor 27 fixedly embedded on the outside of the support frame four 20 is inserted into the inside of the sponge block 14, after the oil content in the sponge block 14 is increased, the humidity value detected by the thin film humidity sensor 27 is increased, the detection result of the thin film humidity sensor 27 is fed back to the controller of the paste filling template hydraulic support 1, the controller issues an alarm and displays the number of the water outlet piece 6 corresponding to the sponge block 14, reminding the staff, so that the staff can quickly locate and repair the rubber tube 8 that may leak, to ensure the safety of the paste filling template hydraulic support 1; and the side of the thin film humidity sensor 27 that detects the change in the humidity value works, the pneumatic cylinder 23 works to contract and drive the support frame five 25 and the support frame four 20 to move, the thin film humidity sensor 27 enters the inside of the air guide groove one 19, the support frame four 20 is flush with the inner wall of the support frame two 11 to block the communication between the inside of the air guide groove one 19 and the inside of the support frame two 11, and the support frame three 13 is released.

[0104] The staff who get the reminder will push the support frame three 13 to detach from the inside of the support frame two 11. If the manual detection finds that the wetness of the sponge block 14 rises due to the rupture of the connection between the water outlet 6 and the connecting piece 7 or the connection between the rubber tube 8 and the connecting piece 7, or the breakage of the rubber tube 8 causes part of the hydraulic oil to move along the outer wall of the rubber tube 8 and be absorbed by the sponge block 14, the connecting piece 7 and the rubber tube 8 are replaced, the inside of the support frame two 11 is cleaned, then the clean support frame three 13 is installed in the inside of the support frame two 11, the clean sponge block 14 is in contact with the connection between the water outlet 6 and the connecting piece 7 or the connection between the rubber tube 8 and the connecting piece 7, and the leakage repair work is completed.

[0105] If the staff finds that there is no leakage phenomenon, a new support frame three 13 and a sponge block 14 can be installed on the support frame two 11.

[0106] After receiving the detection result feedback of the thin film humidity sensor 27, the controller of the paste filling template hydraulic support 1 controls the pneumatic cylinder 23 to work and shrink, so that the thin film humidity sensor 27 enters the inside of the air guide groove one 19. Then the controller controls the positive and negative motor 39 to work and drive the air guide piece six 32 to rotate, so that the air guide piece six 32 is in communication with the air guide piece four 29. The high-speed airflow in the air guide piece five 30 flows through the inside of the air guide groove one 19. The airflow flowing through the inside of the air guide groove one 19 dries the thin film humidity sensor 27 in the inside of the air guide groove one 19, so that the outside of the thin film humidity sensor 27 returns to a dry state. When the replacement of the new support frame three 13 and the sponge block 14 is completed, the controller controls the pneumatic cylinder 23 to work. The thin film humidity sensor 27 is inserted into the inside of the new sponge block 14. Through the cooperation of the support frame three 13, the sponge block 14, the pneumatic cylinder 23, the support frame four 20 and the thin film humidity sensor 27, a leakage monitoring unit is quickly established at the connection between the water outlet 6 and the connecting piece 7 and the connection between the rubber tube 8 and the connecting piece 7, which ensures the monitoring and positioning of the leakage of multiple rubber tubes 8 and reduces the positioning, repair and replacement of the leaking rubber tubes 8 by the staff.

[0107] When the thin film humidity sensor 27 is reset, the positive and negative motor 39 is controlled to reverse and work. The air guide piece six 32 returns to the communication state with the air guide piece seven 34.

[0108] The constant closing end of the three-way valve 47 is controlled to work and open. The air pump 46 sends air to the inside of the air guide box 43 through the three-way valve 47. The air is sent to the inside of the air inflation expansion piece 42 through the air guide box 43 and the air guide elbow 41. The air inflation expansion piece 42 expands. The air inflation expansion piece 42 fills the space in the air guide piece six 32, increases the air pressure in the air guide piece six 32, and meets the effect of adjusting the increase of the air pressure in the air guide piece six 32 without increasing the working power of the air pump 46. The electromagnetic valve 44 is controlled to work and open, so that the air inflation expansion piece 42 is depressurized.

[0109] The inner thread mounting base 40 is separated from the paste filling template hydraulic support 1, the air pump 46 is separated from the paste filling template hydraulic support 1, the plurality of electromagnets 9 are controlled to stop working, the safety monitoring system is separated from the oil circuit board 3, and the hydraulic integrated module 2 can be maintained according to the plan.
