Problems solved by technology
[0003] When the power supply equipment and electrical equipment in the access control management system are working, for example, a large amount of heat will be generated when the power supply is powered. The equipment causes damage, but the existing heat dissipation devices are only installed on the shells of the power supply equipment and the electrical equipment, and only use the thermal conductivity of the radiator itself to transfer heat to the air, which has the problem of poor heat dissipation

The invention discloses a power supply device for entrance guard management, and relates to the field of electric power security control. The power supply device comprises a main loop consisting of apower supply and electric equipment, wherein the main loop is provided with a first breaking part which is connected with a power supply loop of a fan motor in parallel, the power supply loop of the fan motor is provided with a second breaking part, a fan is arranged at one side of power supply equipment; the power supply device also comprises a driving gear and a driven gear which are engaged with each other; a supporting base is provided with a cylinder, a piston is slidingly sealed in the cylinder, the top of the cylinder is provided with an opening which can be shielded by the piston, theopening position of the cylinder communicates with a telescopic bag; one side of the cylinder, which is close to the power supply equipment, communicates with an air bag; end faces of the driving gearand the driven gear both comprise fan-shaped conducting parts and insulating parts. The power supply device of the invention has the beneficial effects that: the problem of poor heat dissipation effect of a heat dissipation device of conventional power supply equipment is solved, heat productivity can be reduced mainly through change of power consumption of the power supply equipment, and the power supply can be cut off timely in abnormal conditions so as to protect circuit security.
Description
technical field [0001] The invention relates to the field of power safety control, in particular to a power supply device for access control management. Background technique [0002] With the progress of the times, security and safety issues are getting more and more attention, so more and more banks, hotels, parking lot management, computer rooms, armories, offices, intelligent communities, factories, etc. choose to install access control management systems. The access control management system integrates microcomputer automatic identification technology and modern security management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. It is an effective measure to solve the security management of the entrances and exits of important departments, and plays a greater role in administrative management such as work environment security and personnel attendance management.
