The invention provides a horizontally pushing type dumper, which can move loaded cargoes backward as a whole to realize unloading. The horizontally pushing type dumper comprises a flat bottom type carriage; the flat bottom type carriage comprises a front breast board, a left side breast board, a right side breast board, a bottom board, front stand columns and rear stand columns; the carriage is internally provided with a push board which is in parallel to the front breast board; the left side breast board, the right side breast board and the bottom board are provided with longitudinal slideways or slide rails; correspondingly, the push board is provided with slide blocks or slide grooves; the left side breast board, the right side breast board and the bottom board form a movable pair with the push board; the push board can move backward and forward along the carriage under the drive of a push board driving device; when the cargoes are unloaded, the push board moves backward; and after the cargoes are unloaded, the push board moves forward to reset. According to the invention, when the cargoes are unloaded, the horizontally pushing type dumper does not need to lift the carriage and can unload the cargoes in the carriage completely only by moving the push board backward; unloading through tipping the carriage is changed to the unloading through horizontal movement, thereby promoting the cargo capacity and the vehicle stability and meanwhile reducing the probabilities that a vehicle frame suffers permanent deformation, and snap of welded joints happens in the carriage and an auxiliary frame.

The invention discloses a flat type dielectric barrier discharge active carbon regeneration reactor amplifying method, belonging to the technical field of environment plasma. The method is characterized in that: multiple flat type dielectric barrier discharge beds are stacked and accumulated to form a unit regeneration reactor; two adjacent flat type dielectric barrier discharge beds share an electrode; a high-voltage electrode and a low-voltage electrode are placed alternately; and multiple unit regeneration reactors are connected in parallel to realize amplification of the regeneration reactor. The invention has the advantages that: the reactor has a simple structure and is convenient to operate and manage; the electrode is shared, has a parallel structure and saves half of electrode materials in comparison with the conventional electrode structure; the reactor occupies a small area which is 1 / (layer number) of the area of the conventional single-layer reactor structure, and the space utilization rate is high; the reactor is easily applied to large-scale regeneration of active carbon; and a processing object can be expanded to other solid adsorbents or materials.

The invention specifically relates to an opening and closing device for passage valves of main and auxiliary combustion chambers of a dimethyl ether engine. Its technical scheme is: the valve cam (1) is installed on the intake or exhaust camshaft, the first flat chassis (2) is in contact with the valve cam (1), and the first cylinder piston rod (3) is in contact with the first flat chassis. (2) Fixed connection, the rodless chamber of the first cylinder (4) communicates with the A port of the corresponding two-position two-way solenoid valve (6) and the rodless chamber of the second cylinder (8) through a three-way pipe joint , the accumulator (5) is connected to the P port of the two-position two-way solenoid valve (6), the two-position two-way solenoid valve (6) is externally connected to the ECU module (7), and one end of the second cylinder piston rod (9) is connected to the first The second flat chassis (10) is fixedly connected, the second cylinder piston rod (9), the second flat chassis (10) and the valve stem (15) are located on the same axis, and the valve stem (15) is sequentially installed with valve lock clips (12 ), upper valve spring seat (11) and return spring (13). The opening and closing device of the channel valve has the characteristics of variable timing and lift, which can reduce curb weight and improve combustion efficiency.

The invention provides a flying car, which has the function of four-wheel independent electric drive, and includes a chassis, a wheel propeller assembly installed on the chassis, and an overturning mechanism assembly. The belt brake is used to control the planetary gear mechanism to realize the hub motor to drive the wheel or propeller to rotate. The turning mechanism assembly can be used to turn the wheel propeller assembly vertically or parallel to the ground. When switching between car mode and flight mode, the planet carrier or the wheel can be fixed by controlling the tightening of the brake band of the planet carrier or the ring gear, so that the output power of the hub motor can be transmitted to the wheel or the propeller shaft , to enter car mode or airplane mode. In addition, the propeller blades can be retracted under the action of the return spring, which is convenient to be integrated with the wheels. It can perform in-situ vertical lift and fly smoothly without affecting other vehicles, and at the same time, it can also improve the problem of poor passability of existing vehicles.
