[0002] In the coking industry, monitoring coke oven pressure is a crucial daily task in coking production. Among these tasks, monitoring the pressure through the oscillating hole is a key indicator that directly reflects the control of the heating airflow in the coke oven; excessively high or low pressure can cause significant damage. Monitoring the oscillating hole pressure is the most frequent and essential daily task in coke oven pressure management.

[0003] The invention disclosed in the existing patent announcement number CN116396764A is an automatic pressure detection device for the inspection hole of a vehicle-mounted coke oven, including a connected inspection hole pressure measuring device, a lifting bracket and a cylinder system; the inspection hole pressure measuring device is set directly above the standard fire channel of the inspection hole of the coke oven, and the inspection hole pressure measuring device includes a pressure measuring head, a base, a pressure measuring tube, a flexible tube and a pressure plate. The pressure measuring head is hemispherical, and a pressure measuring hole is opened in the lower part of the pressure measuring head. A pressure measuring tube is set inside the pressure measuring head, and a flexible tube is connected to the upper end of the pressure measuring tube. The other end of the flexible tube is connected to a pressure detector. A pressure plate is fixedly connected to the upper part of the pressure measuring head, and a base is set on the pressure measuring head. One side of the pressure measuring head is connected to the lifting bracket through the base.

[0004] The above technical solution has a simple structure and is easy to operate. By connecting with the lifting bracket and cylinder system, it realizes the pressure detection function of the coke oven inspection hole, which saves costs and simplifies the device. However, the above technical solution has the problem that when the detection head is not used for a long time, a lot of dust will accumulate on the detection head, and the structure of using a protective shell cannot make installation and disassembly convenient, which is not conducive to user use and maintenance.
