The invention relates to the technical field of barrier gate equipment, in particular to an in-and-out double-control barrier gate and barrier gate stabilizing device.The in-and-out double-control barrier gate comprises a gate machine and a barrier rod, the gate machine comprises a base, a shell, a recognition device and an assembling sliding frame, the base is fixedly connected through a fixing screw, the shell is vertically fixed to the top face of the base, the recognition device is fixed to the top face of the shell, and the assembling sliding frame is fixedly connected with the shell; an assembling sliding frame is arranged on one side of the shell, a rotating cylinder is horizontally fixed to the tops of the vertical end faces of the two sides of the shell in a penetrating mode, a rotating shaft is horizontally and rotationally connected into the rotating cylinder, rotating plates are rotationally installed on the two sides of the rotating shaft in a penetrating mode, and the top ends of the rotating plates are fixed to the inner top face of the shell. The problems that components in the barrier gate are pulled to be bent and broken and the service life of the barrier gate is affected due to the fact that the barrier gate falls rapidly during rod falling are solved, falling of the barrier gate is effectively protected, falling is buffered, and the service life of the barrier gate is prolonged.

The invention provides a filament calibration method and device, electronic equipment, a storage medium, a program product, an X-ray generator and CT equipment. The lamp filament calibration method is used for correcting the mapping relation between the sampling current of a lamp filament in an X-ray generator and the tube current of a ray generating tube, the mapping relation comprises a lamp filament correction coefficient, and the method comprises the following steps: connecting a high-voltage power supply and the ray generating tube, and obtaining the sampling current of the ray generating tube as a first sampling current; when the first sampling current is equal to a preset current, acquiring a sampling current of the filament as a second sampling current; and according to the second sampling current and a preset filament preheating current, a filament correction coefficient is calibrated, and a set relation exists between the set current and the filament preheating current.

The utility model relates to the technical field of drainage devices, and discloses a rapid drainage device for an ultrahigh pressure container, which comprises a pressure container, a branch pipe is fixedly connected to the bottom of the pressure container, a water pump is fixedly connected to one side of the branch pipe, the input end of the water pump is fixedly connected to one end of the branch pipe, and the output end of the water pump is fixedly connected with a first water outlet pipe. A limiting ring is fixedly connected to the outer wall of the first water outlet pipe, a limiting assembly is arranged on the outer wall of the limiting ring, and a second water outlet pipe is slidably connected to the outer wall of the limiting ring. According to the utility model, the second water outlet pipe and the first water outlet pipe are sealed through the sealing ring to prevent leakage during drainage, and the first water outlet pipe and the second water outlet pipe are slidably limited in the limiting groove through the limiting block during buffering, so that the effect of sealing and limiting between the first water outlet pipe and the second water outlet pipe is achieved; the problem of water leakage caused by no sealing structure between the branch pipe and the outer pipe is solved, and the practicability of the rapid drainage device for the high-pressure container is improved.

This utility model relates to the field of electric actuator technology, and particularly to an electric actuator with automatic overload protection. It includes a valve body, a sliding hole bracket vertically fixed to one side of the valve body's outer wall, and a perforated plate horizontally fixed to the top of the valve stem at the upper part of the valve body. A positioning cylinder is vertically fixed to the top surface of the perforated plate. An electric actuator body is vertically mounted on the upper side of the valve body and slidably assembled on the sliding hole bracket. A rod cylinder is vertically mounted at the bottom of the output end of the electric actuator body and is fitted into the positioning cylinder for limiting. This utility model avoids the problem of impact force being converted into torque on the valve stem. Large torque transmitted to the electric actuator motor can easily damage the motor and affect its service life, thus improving the service life of the electric actuator motor.

The utility model relates to the technical field of net-clamping pools, in particular to a net-clamping pool with locally-reinforced net-clamping cloth, which comprises a net-clamping pool body, the net-clamping pool body is composed of outer net-clamping cloth and inner net-clamping cloth which are bonded with each other, and an annular air bag is mounted at the top of the net-clamping pool body. And a plurality of arc-shaped air bags at equal intervals are mounted between the net-clamping pool body and the annular air bag. According to the net-clamping pool, when the annular air bag is inflated, the multiple arc-shaped air bags are expanded through the multiple through holes, then the net-clamping pool body is supported, the problem that the service life is affected due to the fact that the net-clamping pool body is wrinkled is solved, the durability of the net-clamping pool body is enhanced, and the net-clamping pool body is composed of the outer net-clamping cloth and the inner net-clamping cloth which are bonded with each other, so that the net-clamping pool body is more durable. The thickness of the outer net clamping cloth and the thickness of the inner net clamping cloth are equal to the thickness of existing net clamping cloth, so that the thickness of the net clamping pool body is large, the pressure resistance, impact resistance and high temperature resistance of the net clamping pool body are improved, and the durability of the net clamping pool body is further enhanced.
