Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, and more specifically to cooling equipment for shield machines. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. It plays an important role in the construction of the Guangzhou Tunnel. The shield machine can be used to excavate the rock strata in the mountain. The cutter head at the front end of the shield machine will crush the rock strata, and the integrated shield body at the rear end will support the tunnel to prevent collapse during the excavation process. Therefore, the use of the shield machine can greatly increase the safety and efficiency of tunnel excavation. Nowadays, with the improvement of transportation construction, the number of tunnels is also increasing, and the shield machine has become an important equipment for tunnel excavation.

[0003] Existing shield machines need to be cooled during use, but generally, an air cooler is used to dissipate the heat inside the shield machine. Since there is generally a lot of dust in the working environment of the shield machine, a lot of dust will adhere to the surface of the air cooler, which will affect the heat dissipation effect, increase energy consumption, and be inconvenient to clean.

When the surface of the dustproof net 4 filters more dust, it will cause poor air circulation, thereby affecting heat dissipation. The handle rod 504 is pushed and pulled longitudinally, so that the cleaning brush 502 can clean the dust attached to the surface of the dustproof net 4.

The left side of the fixed frame 201 can be connected to the exhaust duct and other mechanisms, which will not be repeated in this application. The heat sink 202 has good thermal conductivity, and the water inlet pipe 203 sends cooling water into the interior of the heat sink 202. Water has a large specific heat capacity and can absorb more heat inside the shield machine. The water with the increased temperature absorbed by the heat passes through the bend pipe 205 to absorb heat from each heat sink 202. , and finally discharged through the outlet pipe 204, thereby realizing the function of cooling the inside of the shield machine. In the process of air flow driven by the fan blades 208, the dust in the air is filtered and intercepted by the dustproof net 4 to prevent dust from accumulating on the surface of the heat sink 202 and affecting the heat absorption of the heat sink 202 and the cooling water. When the surface of the dustproof net 4 filters a lot of dust, it will cause poor air circulation, thereby affecting heat dissipation.
