The invention relates to an outside-vehicle image auxiliary driving method, device and equipment, a medium and a forklift, and the method comprises the steps that current image data collected by all cameras are received, and the current image data collected by different cameras are image data collected from different angles outside a vehicle owner; splicing the current image data to obtain a panoramic image outside the vehicle owner; and sending the panoramic image to a visual display, so that the visual display provides the panoramic image for a driver in the vehicle owner. According to the method, the driving operation of the driver is assisted through the panoramic image outside the vehicle, the problem that the driver has a view blind area outside the vehicle is greatly solved, a wider view angle is provided, the driver can conveniently observe surrounding conditions in real time, and the possibility of collision in the driving process is reduced.

This application provides a charging device, a charging cloud platform, and a charging system. The charging device includes a temperature controller and a temperature sensor. The temperature sensor detects the temperature of the charging device, and the temperature controller adjusts the temperature of the charging device. The charging device is used to: transmit temperature control data during the output of DC power, including the temperature from the temperature sensor and the corresponding rotational speed of the temperature controller; receive an empirical temperature control curve, which is a curve showing the relationship between the temperature of the charging device and the rotational speed of the temperature controller. The empirical temperature control curve is fitted based on temperature control data from at least two charging devices, including the charging device itself and other charging devices besides the charging device; and control the rotational speed of the temperature controller based on the empirical temperature control curve and the temperature from the temperature sensor. The solution provided in this application can reduce the R&D investment in temperature control characteristics, thereby reducing economic and labor costs.

The present invention relates to the field of construction equipment technology, and in particular to a preparation method and equipment for green energy-saving integrated bricklaying and plugging materials. The preparation method includes the following steps: washing, drying, crushing and screening the selected raw materials through a preparation tank, mixing and stirring the screened mixed raw materials through a stirring tank; dust removal treatment for the dust generated during the mixing process of the mixed raw materials; primary stirring and secondary stirring of the mixed raw materials after dust removal treatment, and making the dust removal process more standardized by controlling the extraction speed of the dust removal device; secondary determination of the transition from the block stage to the stirring stage by an imaging device; generating a corresponding torque change curve by a first torque sensor and a second torque sensor, and analyzing the change curve to determine whether the mixed raw materials are mixed uniformly. The present invention solves the problem that the quality of the final mixed product cannot be guaranteed due to the lack of a method for uniformly mixing the raw materials.

The utility model discloses an impeller with an anti-blocking effect for a submersible pump, which relates to the technical field of impellers for submersible pumps and comprises a submersible pump main body. A rotating rod is arranged in the submersible pump body, a plurality of hollowed-out impellers are installed on the surface of the rotating rod, the hollowed-out impellers are evenly arranged, each hollowed-out impeller is composed of a connecting sleeve, a partition plate and hollowed-out blades, the connecting sleeve is arranged in the middle of the surface of the hollowed-out impeller, and the hollowed-out blades are arranged on the surface of the connecting sleeve. Compared with an existing impeller for a common submersible pump, according to the impeller for the submersible pump with the anti-blocking effect, the periphery of the impeller is hollowed out, so that the water outlet area of the water outlet can be increased, the situation that the water outlet is blocked by dirt during water pumping is avoided, and meanwhile the water outlet efficiency is improved; and the load of the direct current motor during working is reduced, so that the direct current motor can work efficiently for a long time, and the maintenance cost is reduced.
