The invention provides a dust removing curtain device for a development machine, and belongs to the field of engineering machinery. The device comprises a curtain, a positive pressure wind cylinder, a negative pressure wind cylinder, and a dust removing fan and a dust remover sequentially connected with the negative pressure wind cylinder. The curtain is arranged on a development machine body and divides a development roadway into two parts, the positive pressure wind cylinder and the negative pressure wind cylinder are respectively arranged on two sides of the curtain, and the operating compartment of the development machine is arranged on the side where the positive pressure wind cylinder is positioned. The development roadway is divided into two parts by adopting the curtain device; the purpose of removing dust in the roadway is fulfilled by using circulating airflow formed by the positive pressure wind cylinder and the negative pressure wind cylinder; and meanwhile, because an operator is positioned at the side of the positive pressure wind cylinder, the operator is isolated from dust, the working environment of a development worker is improved and the physical and psychological health of the development worker is ensured.

The invention discloses an automobile windshield obstruction detection and auxiliary driving system and method, belonging to the technical field of automobile active safety; the system includes a camera, a laser radar, a data processing unit, double flashing lights, a wiper, an acceleration sensor, and a direction machine and brake actuators, the present invention detects the blocking situation on the windshield of the car through the ingenious layout of the camera, so that in an emergency, the car can automatically turn on the wiper to remove the blocking object, and at the same time, turn on the double flashing lights , warn the surrounding vehicles, ensure the driver's line of sight, and greatly improve the driving safety in emergencies.

The invention relates to the technical field of firefighting, and discloses a smoke alarm device for firefighting, which includes a housing and a wall. The inside of the housing is fixedly connected with a photosensitive component, the inside of the housing is fixedly connected with lamp beads, and the inside of the housing is fixedly connected with The filter membrane is fixedly connected with an electromagnet inside the shell, and is connected with a touch plate inside the shell. The outside of the touch plate is fixedly connected with a fixed assembly, and the outside of the fixed assembly is connected with a clamp rod. Under the interaction between all the structures of the device, the device can exhaust the indoor environment when it is used under normal conditions, which not only ensures the smooth flow of air in the indoor environment, but also makes the smoke emission point far away. The smoke can be gathered to the outside of the device, and the smoke alarm function can be played in time, so that the smoke alarm function of the device is more sensitive.

The invention relates to a device for automatical balance of temperature difference inside and outside a car window and a working process of the device. The device comprises at least one of the following devices: a cold-warm air device and a cold-warm electric device, wherein 1) the cold-warm air device comprises a cold-warm air source, the cold-warm air source reaches each car window through an air pipe; a booster fan and a solenoid control valve are arranged on the path of the air pipe, and a motor for adjusting the power of the booster fan is arranged on the booster fan; and 2) the cold-warm electric device comprises a semiconductor having a peltier effect and a current generator for controlling the intensity and direction of the current passing through the semiconductor, and the semiconductor is placed at a position close to each car window. According to the invention, each part of the cold-warm air device and the cold-warm electric device is independently controlled, and can be flexibly and selectively used according to the practical situation, so that energy consumption is reduced as far as possible while the purpose of using is achieved, and the characteristic of saving energy is provided; and 2) a sensor is arranged on the device disclosed by the invention, so that the concrete state of each car window can be detected so as to keep the best working state of each car window, guarantee the sight of a driver and ensure safe driving.

The invention discloses a shielding and protection device for a windscreen of a military transport vehicle. The shielding and protection device comprises a fixed plate which is arranged at the top of a cab, wherein the fixed plate is arranged along the upper edge of a car window; the fixed plate is respectively provided with rotary arms which are in rotary match with the fixed plate along the two sides of the car window; a venetian blind which can be overturned is arranged between the rotary arms along the car window; the venetian blind adopts a nylon alloy plate or a polyethylene fiber bulletproof plate and is provided with a groove for guiding a bullet shrapnel to slide away, so that the venetian blind has the bulletproof function and the safety of a driver and passengers can be protected; the venetian blind can be used for shielding reflected light of window glass and the vehicle is prevented from being exposed to enemies; the angle of a blade of the venetian blind is adjusted so as to ensure the sight of driving the vehicle.
