The invention belongs to the technical field of circuit protection, in particular to a protection method of an asynchronous motor. The high-voltage circuit breaker protector used in the method comprises a frame body, a driving module and a driven module. The upper and lower surfaces of the frame body are respectively provided with two active modules; The frame is provided with a driven module; Asthe voltage increase, heat is generated to heat mercury, the T-shape insulating rod is moved upward to make the first contact disconnect from the second contact, the electromagnetic generator is stopped from supplying power, the brake rod is moved downward to drive the upper bearing plate and the lower bearing plate to do opposite movement, and the two electric contact balls are separated under the action of the elastic rope, so that the main circuit is disconnected; When the temperature returns to normal, As mercury contract more slowly, the shrinkage of mercury is accelerated through the elastic force of the first spring and the gravity of the T-shaped insulating rod so that the first contact and the second contact are connected, the electromagnetic generator is normally powered, and thebrake rod is moved upward to drive the upper bearing plate and the lower bearing plate to move in opposite directions, so that the two electric contact balls are contacted, thus realizing the automatic circuit opening and closing.

The invention provides a cloth transfer mechanism, belongs to the technical field of machines and solves the problem of low work efficiency of the existing cloth transfer. The cloth transfer mechanism comprises a pressing plate connecting plate, a front pressing plate and a rear pressing plate; each of the front pressing plate and the rear pressing plate is located below the pressing plate connecting plate and is opposite to two ends of the pressing plate connecting plate; each of the front pressing plate and the rear pressing plate is fixedly provided with a vertically-arranged guide rod penetrating through the pressing plate connecting plate; the pressing plate connecting plate can slide along the guide rods to be close to or far away from the front pressing plate and the rear pressing plate; an elastic buffer part is arranged between the front pressing plate and the pressing plate connecting plate; and an elastic buffer part is arranged between the rear pressing plate and the pressing plate connecting plate. The cloth transfer mechanism drives cloth to move in a static friction way, a cloth clamping part is kept not to have drapes and deformation in the transfer process, influences from a height difference caused by unevenness of a deskboard can be avoided, and the cloth can be kept to be transferred smoothly all the time and can be kept to normally enter the subsequent processing and use, so that the work efficiency is increased.

The present invention relates to the technical field of video image processing, in particular to an intelligent monitoring system and method based on image processing. Display the warning area and the character frame; it is also used to sequentially determine whether the warning area in the image I overlaps with the character frame, if the warning area in the image I of the current frame coincides with the character frame, then obtain the image I within the preset time period as image II ; The image analysis subsystem is used to sequentially calculate the coincidence rate of the warning area and the person frame in the image II, and generate a prediction result according to the coincidence rate. When the prediction result is a stay, a prompt signal is generated; when the prediction result is an intrusion , generating an alarm signal. This solution can remind the security personnel when someone invades the warning area, effectively protect the warning area, and make reasonable use of human resources.

The present invention provides a portable type radon emanation and thorium emanation detector including a detecting chamber, the detecting chamber includes a sampling cavity for sampling and analyzing air, and an exhausting cavity for exhausting the analyzed gas. An air inlet port is arranged on the side wall of the sampling cavity, and a gas exhaust port is arranged on the side wall of the exhausting cavity. The sampling cavity furthermore includes: a filtering part arranged between the sampling cavity and the exhausting cavity; and a sampling part arranged on the position opposite to the exhausting cavity. The portable type radon emanation and thorium emanation detector enables the radon emanation and thorium emanation to combine with an aerosol by utilizing two diffusion cavities separated by glass fibre, and a formed radioactive aerosol daughter is retarded in the filtering part, and alpha particles emitted by the daughter form a radiation damage track on a track detecting element after the alpha particles are emitted to the sampling part. A track density on the track detecting element is detected after accumulated monitoring, thereby calculating various alpha potential energy concentrations caused by the track density.

The invention discloses a dry sludge transportation system and device. The system includes a control module, a feeding module and a transportation module. The control module includes a control box. The feeding module includes a vibration module, an automatic cleaning module, a sticky wall automatic spraying module and an overloading alarm module. The transportation module includes an anti-idling automatic detection module, a driving motor, a gear box and a rotor pump. The system is scientific, reasonable and safe and convenient to use, the arrangement of the rotor pump makes the occupied areaof the device reduced, the transportation efficiency of the device is effectively improved, the friction time between materials and a rotor is reduced, the wear pressure of the materials on a rotor-pump chamber is thus reduced, wear of accessories is reduced, the system has the functional advantages of energy conservation and high efficiency, the materials are thus not stuck or overhead in a feeding hopper, the materials can normally enter the rotor pump, idling of the rotor pump is effectively avoided, and the service life of the rotor pump is effectively prolonged.

The invention discloses a municipal LED lamp, which comprises a base, a support rod, a lamp body, a top block, and an anemometer. The support rod is embedded between the top of the base and the bottom of the lamp body, and the top block is installed at the center of the top of the lamp body. Position, because the lawn lamp for lawn decoration and lighting scrapes the soil on the top surface of the lamp body through the inclined plate, because the installation height of the lawn lamp is low, preventing the soil in the soil from mixing with water and splashing on the surface of the lamp body, Under the sunlight, the mud and water condense and accumulate, and a thick soil layer is formed on the top surface of the lamp body. The formed soil layer is scraped off to speed up the timely dissipation of heat generated by the lawn lamp, increase the service life of the lamp and reduce the service life of the lawn lamp to ensure the normal operation of the lawn lamp. Lighting, by blocking the ball from rolling in the opening, the steel wire block outside the blocking ball scrapes and collects the soil on the inner wall, preventing the soil from accumulating on the inner wall of the opening and causing the opening to be blocked, so that the soil scraped off the top surface of the lamp body can enter the aggregate normally in the pool.
