[0010] Preferably, a cooling chamber is provided inside the cooling cylinder, an isolation plate is fixed to the inner wall side surface of the cooling chamber, the isolation plate divides the cooling chamber into two parts, and a water inlet is provided on the inner wall of the cooling chamber on the side with a smaller diameter.

[0011] Preferably, the water delivery port is located on the inner wall of the cooling chamber on the upper side of the isolation plate, and the water delivery port corresponds to the pipe opening on the side surface of the water pump, and the pipe opening on the top of the water pump is located inside the rotary drum.

[0012] Preferably, a through hole is opened on the surface of the isolation plate, a fixing block is fixed in the middle of the inner wall of the through hole, a spray hole is opened on the surface of the fixing block, the spray hole penetrates the isolation plate, and the diameter of the spray hole is much smaller than the through hole.

[0013] Preferably, a spiral tube is fixed to the through hole port below the isolation plate, the other end of the spiral tube penetrates the bottom surface of the inner wall of the cooling chamber, and an input water pipe is fixed to the spiral tube port.

[0016] A method for intelligently controlling the temperature of a cutterhead for continuous cutting of a pile wall by a shield machine comprises the following steps:

[0017] Step 1: Cooling. When the temperature of the cutter disc rises, the temperature sensor will send a signal to the water pump. The water pump will start to input the condensing agent in the upper layer of the cooling chamber into the transfer tube. The condensing agent in the transfer tube is transported to the guide pipe through the output water pipe.

The condensing agent that boils into gas will enter the compressor. The compressor will pressurize the gas condensing agent and input the pressurized gas condensing agent into the spiral tube in the lower layer of the cooling cylinder through the input water pipe. Since the spiral tube is spiral, the length of the pipeline is greatly increased, and the temperature in the cooling chamber is much lower than the surface temperature of the blade disc, the pressurized gas condensing agent will be cooled into pressurized liquid condensing agent in the spiral tube. The pressurized liquid condensing agent in the spiral tube will pass through the spray hole. Since the diameter of the spray hole is very small, the pressurized liquid condensing agent will become water mist when passing through the spray hole, and the pressure will be released at the same time. This process will further reduce the temperature of the condenser, so that the condenser will restore the extremely low temperature in the upper layer of the cooling chamber, waiting for the water pump to transport it. The condensing agent of this cooling method is recycled, and there is no need to waste a lot of water resources.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The temperature sensor sends a signal to the water pump to input the condensate in the upper layer of the cooling chamber into the transfer tube, and then transport it to the guide pipe. The condensate will cool the cutterhead in the guide pipe and the cooling water pipe. This cooling method can cool the cutterhead without shutting down the shield machine. Since the boiling point of the condensate is very low, the condensate will change from liquid to gas when cooling the cutterhead and absorbing heat. The compressor will pressurize the gas condensate, and then input the pressurized gas condensate into the spiral tube in the lower layer of the cooling tube. Since the spiral tube is spiral, the pipeline length is greatly increased. degree, and the temperature in the cooling cabin is much lower than the surface temperature of the blade disc, so the pressurized gas condensing agent will be cooled into pressurized liquid condensing agent in the spiral tube, and then the pressurized liquid condensing agent in the spiral tube will pass through the spray hole. Since the diameter of the spray hole is very small, the pressurized liquid condensing agent will turn into water mist when passing through the spray hole, and the pressure will be released at the same time. This process will further reduce the temperature of the condensing machine, so that the condensing machine will restore the extremely low temperature in the upper layer of the cooling cabin, waiting for the water pump to transport it. The condensing agent of this cooling method is recycled, and there is no need to waste a lot of water resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0031] A flow cylinder 6 is fixed on the upper surface of the cooling cylinder 8, and the water pump 11 will start to input the condensing agent in the upper layer of the cooling chamber 15 into the flow cylinder 6, and then the condensing agent in the flow cylinder 6 is transported to the guide pipe 10 through the output water pipe 7. A cooling water pipe 9 is fixed on the lower surface of the cooling cylinder 8, and a guide pipe 10 is fixed at the end of the cooling water pipe 9. The output water pipe 7 is fixed on the outer surface of the guide pipe 10. Since the guide pipe 10 and the cooling water pipe 9 are in contact with the surface of the cutter disc 3, the condensing agent will cool the cutter disc 3 when in the guide pipe 10 and the cooling water pipe 9, and the end of the output water pipe 7 is connected to the flow cylinder 6.

[0032] On the basis of Example 1, in order to achieve high efficiency in reducing the temperature of the shield machine cutter head, the thickness of the blade 4 is much larger than the thickness of the temperature sensor 5, and multiple groups of blades 4 and temperature sensors 5 are provided. The temperature sensor 5 is located between the multiple groups of blades 4. The height of the protective wall 2 is higher than the height of the flow tube 6, so the ground will not cause damage to the temperature sensor 5 when the cutter head 3 is in use. The diameter of the protective wall 2 is larger than the diameter of the guide tube 10, so the cooling component is located in the protective wall 2.

[0033] The bottom end of the water pump 11 is fixed on the surface of the cutter disc 3, a cooling cylinder 8 is fixed on the outer surface of the water pump 11, an output water pipe 7 is fixed on the outer arc surface of the flow tube 6, and the other end of the output water pipe 7 is connected to the guide pipe 10. The output water pipe 7 transports the extremely low temperature condensing agent to the guide pipe 10 and the cooling water pipe 9, which will cool the cutter disc 3.

[0034] A cooling chamber 15 is provided inside the cooling cylinder 8, and an isolation plate 16 is fixed to the inner wall side surface of the cooling chamber 15. The isolation plate 16 divides the cooling chamber 15 into two parts. The two cooling chambers 15 will cool down the condensing agent. A water inlet 14 is provided on the inner wall of the cooling chamber 15 on the side with a smaller diameter.

[0035] The water inlet 14 is located on the inner wall of the cooling chamber 15 on the upper side of the isolation plate 16, and the water inlet 14 corresponds to the pipe opening on the side surface of the water pump 11. The pipe opening at the top of the water pump 11 is located inside the transfer tube 6. The water pump 11 will start to input the condensing agent on the upper layer of the cooling chamber 15 into the transfer tube 6.

[0036] A through hole 18 is provided on the surface of the isolation plate 16, a fixing block 19 is fixed in the middle of the inner wall of the through hole 18, a spray hole 20 is provided on the surface of the fixing block 19, the spray hole 20 penetrates the isolation plate 16, and the diameter of the spray hole 20 is much smaller than the through hole 18. Since the diameter of the spray hole 20 is very small, the pressurized liquid refrigerant will turn into water mist when passing through the spray hole 20, and the pressure will be released at the same time. This process will further reduce the temperature of the condenser.

[0037] A spiral tube 17 is fixed to the port of the through hole 18 below the isolation plate 16, and the other end of the spiral tube 17 penetrates the bottom surface of the inner wall of the cooling chamber 15. An input water pipe 12 is fixed to the port of the spiral tube 17. Since the spiral tube 17 is spiral-shaped, the length of the pipeline is greatly increased, and the temperature in the cooling chamber 15 is much lower than the surface temperature of the cutter disc 3, so the pressurized gas condensate will be cooled into pressurized liquid condensate in the spiral tube 17.

[0038] The input water pipe 12 is fixed to one group of ports of the compressor 13, and the other group of ports of the compressor 13 is fixed with a cooling water pipe 9, which is connected to the guide pipe 10. The compressor 13 will pressurize the gas condensing agent.

The condensing agent is recycled and there is no need to waste a large amount of water resources.

[0040] The present invention also discloses a method for intelligently controlling the temperature of a cutter head for continuous cutting of pile walls of a shield machine, comprising the following steps:

[0041] Step 1: Cooling. When the temperature of the cutter disc 3 rises, the temperature sensor 5 will send a signal to the water pump 11. The water pump 11 will start to input the condensing agent in the upper layer of the cooling chamber 15 into the flow tube 6. The condensing agent in the flow tube 6 is transported to the guide pipe 10 through the output water pipe 7. Since the guide pipe 10 and the cooling water pipe 9 are in contact with the surface of the cutter disc 3, the condensing agent will cool the cutter disc 3 in the guide pipe 10 and the cooling water pipe 9. This cooling method can cool the cutter disc 3 without shutting down the shield machine.

[0042] Step 2: Circulation. Since the boiling point of the condensing agent is very low, the condensing agent will change from liquid to gas when cooling the blade disc 3 and absorbing heat. The condensing agent that boils into gas will enter the compressor 13. The compressor 13 will pressurize the gas condensing agent and input the pressurized gas condensing agent into the spiral tube 17 in the lower layer of the cooling cylinder 8 through the input water pipe 12. Since the spiral tube 17 is spiral, the length of the pipeline is greatly increased, and the temperature in the cooling chamber 15 is much lower than the surface temperature of the blade disc 3, the pressurized gas condensing agent will be cooled into pressurized liquid condensing agent in the spiral tube 17. The pressurized liquid condensing agent of the spiral tube 17 will pass through the spray hole 20. Since the diameter of the spray hole 20 is very small, the pressurized liquid condensing agent will become water mist when passing through the spray hole 20, and the pressure will be released at the same time. This process will further reduce the temperature of the condenser, so that the condenser will restore the extremely low temperature in the upper layer of the cooling chamber 15, waiting for the water pump 11 to transport it. The condensing agent of this cooling method is recycled, and there is no need to waste a lot of water resources.

Since the guide pipe 10 and the cooling water pipe 9 are in contact with the surface of the cutter disc 3, the condensing agent will cool the cutter disc 3 while in the guide pipe 10 and the cooling water pipe 9. This cooling method can cool the cutter disc 3 without shutting down the shield machine; since the boiling point of the condensing agent is very low, the condensing agent will change from liquid to gas when cooling the cutter disc 3 and absorbing heat, and then the condensing agent that boils into gas will enter the compressor 13, and the compressor 13 will pressurize the gas condensing agent, and then the pressurized gas will be The gas condensate is input into the spiral tube 17 in the lower layer of the cooling cylinder 8 through the input water pipe 12. Since the spiral tube 17 is spiral, the length of the pipeline is greatly increased, and the temperature in the cooling chamber 15 is much lower than the surface temperature of the blade disc 3, so the pressurized gas condensate will be cooled into a pressurized liquid condensate in the spiral tube 17, and then the pressurized liquid condensate in the spiral tube 17 will pass through the spray hole 20. Since the diameter of the spray hole 20 is very small, the pressurized liquid condensate will become water mist when passing through the spray hole 20, and the pressure will be released at the same time. This process will further reduce the temperature of the condenser, so that the condenser will restore the extremely low temperature in the upper layer of the cooling chamber 15, waiting for the water pump 11 to transport it. The condensate of this cooling method is recycled, and there is no need to waste a lot of water resources.
