This invention relates to the field of building canopy technology. To address the lack of interception capabilities for falling objects from heights in existing building canopies, this invention discloses a building buffer canopy designed to prevent such incidents. The canopy includes a roof panel, with a mounting housing at one end. An inclined buffer plate is movably mounted on the side of the mounting housing near the roof panel. In use, when a falling object lands on the buffer plate, the buffer airbag is compressed and deformed. Air from the buffer airbag is then transported via a connecting pipe to a blocking airbag. The inflated blocking airbag extends from the mounting housing and blocks the side of the buffer plate, preventing the falling object from sliding off and causing danger. Simultaneously, an alarm sounds, alerting people to stay away from the area around the roof panel and prompting staff to promptly check and remove any falling objects intercepted by the blocking airbag on top of the buffer plate, thus enhancing safety.

This invention discloses a high-temperature alarm device for a plum blossom contact, relating to the field of electrical component temperature monitoring technology. It includes a contact mounting unit, a temperature monitoring unit, and an alarm unit. The contact mounting unit includes an upper contact mounting assembly disposed at one end of the plum blossom contact base and a lower contact mounting assembly disposed at the other end of the plum blossom contact base. The temperature monitoring unit includes a temperature sensing component disposed on the upper contact mounting assembly. This high-temperature alarm device for a plum blossom contact, by incorporating an alarm unit and a fusible metal that melts under high-temperature conditions, achieves the function of reflecting alarm signals using a refractive element under high-temperature conditions, thereby sending alarm signals to an alarm device for alarm activation. This allows the temperature monitoring module disposed on the plum blossom contact to quickly trigger an alarm when the temperature of the plum blossom contact rises to 95 degrees Celsius without requiring a power supply, ensuring that the switch plum blossom contact does not suffer more serious short-circuit accidents due to prolonged overheating.

The present application relates to a method for automatically regulating the deviation wear of the sucker rod in the horizontal well oil production, observing the load sensor after starting, at this time the load value is the maximum; the sucker rod rotates at a set speed or does not rotate while being lowered; during the lowering process, when the load weight starts to decrease, it means that the bottom device of the equipment touches the bottom of the sucker rod; the oil pumping is carried out under the current working parameters, and the real-time value of the torque is monitored; if the torque exceeds the set early warning torque, the optimization operation is executed, and the change of the torque after the optimization operation is judged; after the optimization operation, if the torque is lower than the set early warning torque, the normal mining is continued; if the torque still exceeds the early warning value after the speed and / or the range of lifting the sucker rod are exceeded, the sucker rod is lifted to the preset position, and the initial step is repeated; thereby effectively regulating the torque to make it in the best state, reducing or even avoiding the occurrence of deviation wear, greatly improving the service life of the sucker rod, and having good practicability.
