The invention provides a temporary password usage control method and system. The method comprises the steps that after a random code generation end and a random code usage end match successfully, therandom code generation end generates the preset number of temporary passwords; the random code generation end sends the temporary passwords to the random code usage end for storage; and the random code usage end receives a current temporary password and compares the current temporary password with the pre-stored temporary passwords, and if the current temporary password is consistent with an appointed temporary password in the pre-stored temporary passwords, the check is successful. According to the method and the system, a plurality of temporary passwords can be generated at one time; throughaddition of function codes to the temporary passwords, the usage of the temporary passwords is controlled and managed; the temporary passwords can be remotely sent to temporarily authorized users invarious modes; and the temporarily authorized users do not need to operate an APP to obtain the passwords for unlocking.

The invention discloses a sunshine room roof leakage-proof method. Primary drainage channels and secondary drainage channels are formed in primary beams and secondary beams, and leakage holes are formed in the secondary drainage channels of the primary beams and communicated with the primary drainage channels. Drainage channel openings of the primary drainage channels of the secondary beams are higher than drainage channel openings of the primary drainage channels of the main beams, and a large amount of rainwater is freely drained from top to bottom. During second drainage, bearing bosses are formed on the outer side walls of the secondary drainage channels of the primary beams and the secondary beams, rubber channels are formed in bearing surfaces of the bosses, waterproof rubber is mounted in the rubber channels, glass is pressed on the waterproof rubber by the aid of weight, and the rainwater is stopped at the secondary drainage channels by the waterproof rubber and guided into the secondary drainage channels of the primary beams. The rainwater flows into the primary drainage channels through the leakage holes in the secondary drainage channels of the primary beams and is smoothly drained. The invention further discloses a sunshine room roof structure. Organized drainage is realized, roof leakage is effectively avoided, wires and pipes are distributed, the cost is low, and the heat insulation effect is fine.

The invention discloses a discharging mechanism of straw discharge cleaning on the upper part of a straw methane anaerobic tank and the discharging mechanism is characterized by comprising a cleaning device and a spraying mechanism, wherein the cleaning device is installed on the cabin top of an anaerobic tank in a suspension mode; the spraying mechanism is arranged on the cabin top of the anaerobic tank; the cleaning device comprises a rotary shaft and a blade, wherein the rotary shaft penetrates through the cabin top of the anaerobic tank, and extends downward vertically to the part above aliquid level; the blade is installed on the rotary shaft in a fixed mode, and the rotary surface of the blade and the water level form an inclined angle of 60 degrees; a power driven mechanism which is used for driving the rotary shaft to perform a rotary motion and is composed of a motor and a speed reducer is installed on the cabin top of the anaerobic tank through a supporting frame; and the extending section connected by the rotary shaft of the cabin top of the anaerobic tank and the speed reducer is provided with a water seal.

The invention discloses a quick change connector device for a hose assembly pressure test and a hose assembly pressure test system. The quick change connector device for the hose assembly pressure test comprises a transitional connector, a piston cylinder and a transitional core which are sequentially connected with one another, wherein a piston-free cavity in the cylinder body of the piston cylinder is communicated with the transitional connector; one end of the transitional core is sleeved with a piston of the piston cylinder; the other end of the transitional core is provided with a structure connected with a hose assembly connector; a communicating pipeline is formed on the piston; a liquid guiding hole is formed in the transitional core; and a pressure control valve for communicatingthe liquid guiding hole and the communicating pipeline when pressure is higher than a set value is arranged between the liquid guiding hole and the communicating pipeline. The hose assembly pressure test system comprises a pressure test loop, and a boosting pump and two connector devices which are arranged on the pressure test loop; a hose assembly to be tested is connected between the two connector devices; and the connector devices are the quick change connector devices. The quick change connector device for the hose assembly pressure test and the hose assembly pressure test system have theadvantages of improving installing speed, improving test efficiency, reducing labor intensity and the like.

The invention relates to a sealing device for a long-range transport ship-loading system, belonging to the technical field of mechanical equipment; and the sealing device is used for sealing the tail end of a loading pipe of the ship-loading system and a ship cabin. The sealing device comprises a fixing plate which is used for sealing an opening of the ship cabin and can be fixedly connected with side plates at the two sides of the opening of the ship cabin; and the fixing plate is provided with a feeding port which can be hermetically connected with the tail end of the loading pipe. The sealing device further comprises a dust collecting box, wherein the dust collecting box is arranged on the fixing plate, the bottom wall of the dust collecting box is provided with through holes which are communicated with the ship cabin, and the dust collecting box is provided with an interface which is used for being connected with an exhaust pipe of the ship cabin. According to the sealing device disclosed by the invention, the problems of dust rise and low ship-loading efficiency of the existing long-range transport ship-loading system because the tail end of the loading pipe can not be hermetically connected with the ship cabin are solved; the sealing device has the advantages of convenience in disassembly and assembly and good sealing performance; and a sealing state among the loading pipe, the ship cabin and a dust remover can be formed so as to ensure no dust leakage, and the ship-loading efficiency is consequently increased.

The invention discloses a method and device for preventing enterprise product authorization documents from leaking out. The method includes the following steps: S1. A system deployment module deploys the system to form a deployment environment; S2. Binds the authorization file with the deployment environment; S3. After the system obtains the authorization file, it verifies with the deployment environment; S4. If the verification is passed, the authorization file can be used; if the verification fails, the authorization file cannot be used. Through the above method and device, the authorization file is bound to the deployment environment, the authorization file has no risk of leaking, and the usage restriction of the authorization file can also be achieved in the case of not being connected to the Internet.
