The invention relates to a sweeping car with a single-cycle filtering system. The sweeping car comprises a car chassis, a draught fan, a pumping air flue, a pumping pipe, a pumping disc, a sweeping disc and a water spraying device, wherein the single-cycle filtering system is arranged on the car chassis; the single-cycle filtering system comprises a filter, a sewage tank, a clean water tank, a water pump and a connection pipeline; the sewage tank is connected with the water pump through a pipeline; the water pump is connected with one or more than one filters through a pipeline; the filter is connected with the sewage tank through a pipeline; the filter is provided with a clean water outlet; the clean water outlet is connected with the clean water tank through a pipeline; the filter is a ceramic film filter; the ceramic film filter is formed by arranging a ceramic film pipe in a sealed shell; the two ends of the sealed shell are respectively used as a sewage inlet and a sewage outlet which are connected with a pipeline; the sealed shell is provided with a clean water outlet. The sweeping car with the single-cycle filtering system, provided by the invention, can be widely used for environmental sanitation cars cleaning urban streets; the effective sweeping working time of the sweeping car can be greatly improved, the number of times of filling clean water into the working car at a water station and discharging sewage in a refuse dump is reduced; the purchasing and using cost of cars in a unit working area can be reduced, the emission amount of the sewage is reduced and the utilization rate of water resources is improved.

The invention discloses a washing and sweeping vehicle with a double-circulation filter system. The washing and sweeping vehicle comprises a vehicle chassis, a draught fan, a suction air duct, a suction pipe, a suction plate, a brush plate and a water spraying device. According to the double-circulation filter system, a sewage box is connected with a first-stage water pump through a pipeline, the first-stage water pump is connected with a second-stage water pump through a pipeline, the second-stage water pump is connected with one or more filters. The filter is connected with the sewage box through a pipeline. A pressure regulation valve is arranged on the connection pipeline between the filter and the sewage box. The connection pipeline between the first-stage water pump and the second-stage water pump is connected with the connection pipeline between the filter and the pressure regulation valve through a pipeline. The clear water outlet of the filter is connected with a clear water box through a pipeline. The filter is a ceramic membrane filter which comprises a ceramic membrane pipe arranged in a sealed shell. The two ends of the sealed shell are used as a sewage inlet and a sewage outlet respectively to be connected with pipelines. A clear water outlet is formed in the sealed shell. By means of the washing and sweeping vehicle, the effective working time of environmental sanitation devices can be greatly prolonged, the sewage discharge amount can be decreased, and the utilization rate of water resources is increased.

The invention discloses an elastic non-pneumatic tire and a vehicle. By arranging a wheel hub, an outer bead and a carcass, the carcass is arranged between the wheel hub and the outer bead; wherein, the carcass specifically includes an annular elastic member and a first elastic unit. The elastic member is arranged between the wheel hub and the outer bead, and the first elastic unit is arranged in the inner ring of the annular elastic member to support the annular elastic member. The annular elastic member forms the overall external configuration of the tire and is provided at the shoulder part A certain supporting force, the annular configuration ensures the radial and lateral mechanical properties of the tire, the first elastic unit supports the tread to improve the radial stiffness of the tire, and the elastic characteristics of the annular elastic member and the first elastic unit make the tire have a certain degree of elasticity. The shock absorption effect solves the problem of poor radial and lateral mechanical properties of the existing elastic tire.

The invention relates to the technical field of fog cannons, and discloses a connection structure between the gun barrel and the base of the fog cannon, including a supporting rotating shaft, the outer part of the supporting rotating shaft is fixedly sleeved with a rotating bearing platform, and the outer part of the supporting rotating shaft and A positioning platform is movably socketed under the rotating platform, and an annular slot and an annular boss are arranged on the top of the positioning platform, and the annular slot and the annular boss are arranged alternately. The bottom is provided with an annular card slot and an annular boss. In the present invention, by setting the positioning bearing platform and the rotating bearing platform, the upper electrical control line is terminated to the sliding contact block on the rotating bearing platform, the lower electrical control line is terminated to the fixed slip ring on the positioning bearing platform, and the sliding contact The block and the fixed slip ring are electrically connected by the sliding contact of the contact and the slip ring, so that the upper electrical appliance and the lower electrical appliance can be rotated separately without the influence of the winding of the power control line, and the 360-degree rotation operation of the upper electrical appliance can be fully realized .
