Description

Technical Field

[0001] This utility model relates to the field of electromagnetic door lock technology, specifically to an energy-saving electro-permanent magnet door lock. Background Technology

[0002] An electromagnetic door lock is a security device that uses electromagnetic principles to control a door. It works by using the principle of electromagnetism. When current passes through a silicon steel sheet, the electromagnetic lock generates a strong attraction force that tightly holds the iron plate, thus locking the door.

[0003] Existing electromagnetic door locks need to be kept energized to maintain their magnetic force, resulting in high annual power consumption and increased electricity costs. To reduce power consumption, photovoltaic panels can be equipped on electromagnetic door locks. However, photovoltaic panels are exposed to the environment and are prone to dust and dirt accumulation, which can affect their power supply performance. Therefore, it is necessary to design an energy-saving electro-permanent magnet door lock. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving electro-permanent magnet access control lock, which solves the problem in related technologies that photovoltaic panels are exposed to the environment during use and are prone to dust and dirt accumulation, which affects the power supply effect of the photovoltaic panels.

[0005] The technical solution of this utility model is as follows:

[0006] An energy-saving electro-permanent magnet access control lock includes an electromagnetic lock body. A permanent magnet is screwed onto the outer wall of the electromagnetic lock body. A support frame is provided on the outside of the electromagnetic lock body, with a drive frame welded to one end of the support frame and a guide frame welded to the top of the other end of the support frame. A photovoltaic panel is snapped between the drive frame and the guide frame. A drive groove is formed on the drive frame, and a water guide frame is slidably installed inside the drive groove. A guide rod is screwed to one end of the water guide frame, and the other end of the guide rod extends into the guide frame. A cleaning component is provided at the center of the bottom of the water guide frame. Several nozzles are screwed equidistantly on both sides of the bottom of the water guide frame. A flow pump is screwed to the top of the water guide frame, and a water pipe is inserted into the input end of the flow pump. A motor is screwed to the outside of one end of the drive frame, and a screw rod is inserted into the drive groove. One end of the screw rod is welded and fixed to the output end of the motor. The screw rod and the water guide frame are connected by threads.

[0007] Preferably, the permanent magnet is made of neodymium iron boron magnet, and the interior of the water guide frame is hollow.

[0008] Preferably, the other end of the water guide frame is fitted with a ball bearing, and the bottom of the ball bearing is in contact with the inner wall of the drive groove. The ball bearing is made of stainless steel.

[0009] Preferably, the cleaning assembly includes a spring telescopic rod, a cleaning frame, rubber strips, and sponge strips. The cleaning frame is located below the bottom of the water guide frame. Spring telescopic rods are screwed to both ends of the top of the cleaning frame, and the telescopic ends of the spring telescopic rods are screwed and fixed to the bottom end face of the water guide frame. Several rubber strips are glued at equal intervals to the center of the bottom of the cleaning frame, and sponge strips are screwed to both sides of the bottom of the cleaning frame.

[0010] Preferably, the rubber strip is made of nitrile rubber, and the cleaning rack is T-shaped.

[0011] Preferably, a charge / discharge controller is screwed onto the bottom end face of the photovoltaic panel, and a first cable is provided on the charge / discharge controller. A storage battery is screwed onto the bracket, and an inverter is provided on one side of the storage battery. A third cable is provided on the inverter, and the other end of the third cable is screwed and fixed to the electromagnetic door lock body. The other end of the first cable is connected to the storage battery.

[0012] Preferably, the electromagnetic door lock body is provided with a second cable, and the other end of the second cable is screwed to an access control controller. The bottom of the bracket is provided with a drain outlet, and the drain outlet is located on the lower side of the photovoltaic panel.

[0013] Preferably, a fixing frame is welded to both sides of the bottom end face of the bracket, and a pair of connecting plates are welded to both sides of the fixing frame, and the fixing frame is triangular.

[0014] The beneficial effects of this utility model are:

[0015] By inserting a water pipe into a prepared bucket, a flow pump draws water and delivers it to the water guide frame. Nozzles spray water onto the photovoltaic panels, rinsing away dust. A spring-loaded telescopic rod lowers the cleaning frame, allowing rubber and sponge strips to adhere to the top of the photovoltaic panels. As the water guide frame moves, the rubber strips scrape away dirt, and the sponge strips wipe the panels, improving cleanliness and preventing dust and dirt from adhering to the panels, which would reduce light transmittance and power generation efficiency. Dust and dirt also hinder heat dissipation, accelerating corrosion and aging of the photovoltaic panels. Guide rods and ball bearings ensure smoother movement of the water guide frame, improving stability. A motor-driven screw moves the water guide frame back and forth within the drive groove, enabling repeated cleaning and enhancing the cleaning effect.

[0016] By installing bolts on the connecting plate of the mounting bracket, the bracket can be fixed to the wall. The photovoltaic panel converts solar energy into direct current through the photoelectric effect. The direct current is regulated by the charge and discharge controller and then transmitted to the battery for storage through the first cable. The charge and discharge controller can prevent overcharging or over-discharging and protect the battery life. The power supply from the battery can be delivered to the electromagnetic door lock body through the inverter and the third cable to meet the power supply needs of the electromagnetic door lock body. This method can store energy independently, reduce the use of electricity resources, and play an energy-saving role. Attached Figure Description
