[0002] At present, elevators are widely used in people's daily lives. They are vertical elevators powered by electric motors and are mainly used for carrying people or goods in high-rise buildings. During the use of the elevator, the lights, multimedia, etc. in the elevator car need to be powered. Currently, most of them use the method of dragging traveling cables to power the elevator car. The traveling cables move up and down synchronously with the elevator car, which has the disadvantages of low efficiency and high maintenance costs. Especially in super high-rise buildings and high-speed elevators, excessive elevator speed or long free suspension length will increase the carrying load of the traveling cables, and there are safety risks such as wear, accelerated aging, and unsafe exposure, which greatly reduce the reliability and operating efficiency of the elevator. In view of this, the present utility model is specially proposed. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1:

[0020] Reference Figures 1-4 A floor power station type contactless elevator car power supply device includes: a wireless power supply rail 101 and a wireless power supply 201. The wireless power supply rail 101 is fixedly installed on the side wall of the elevator shaft 1. The wireless power supply 201 is fixedly installed on the elevator car 2 on the side close to the wireless power supply rail 101. The wireless power supply 201 is fixedly connected to a receiving coil 2001 set on the outside of the wireless power supply rail 101; a protective shell 202 is fixedly installed on the elevator car 2 by bolts. The device 201 is arranged inside the protective shell 202, and the protective shell 202 is provided with a through opening for use with the wireless power supply guide rail 101; the protective shell 202 is provided with a through opening 203, and a fan 204 is installed in the through opening 203; a cleaning ring 205 is fixedly installed in the protective shell 202 near the through opening, and the wireless power supply guide rail 101 passes through the cleaning ring 205, and a circle of cleaning brush strips 206 that are in contact with the wireless power supply guide rail 101 is fixedly connected to the inner wall of the cleaning ring 205.

[0021] When powering the electrical equipment in the elevator car 2, a wireless coupling connection method is adopted between the receiving coil 2001 and the wireless power supply rail 101 arranged in the elevator shaft 1, so that the electric energy can be wirelessly transmitted from the wireless power supply rail 101 to the receiving coil 2001, and then transmitted to the elevator car 2 for power supply via the wireless power supply 201, eliminating the elevator accompanying cable. Therefore, there is no need to drag the cable accompanying the elevator car 2, reducing the safety hazards of the elevator operation, and thus improving the stability and reliability of the elevator operation. At the same time, the receiving coil 2001 adopts a specific structure adapted to the wireless power supply rail 101, which can further enhance the efficiency of wireless energy transmission.

[0022] When the wireless power supply 201 and the receiving coil 2001 receive the electric energy transmitted by the wireless power supply rail 101, the fan 204 can be started. The fan 204 will ventilate and dissipate heat for the wireless power supply 201, the receiving coil 2001 and the part of the wireless power supply rail 101 located in the protective shell 202, ensuring that they can operate within the specified temperature range and avoid damage due to excessive temperature, effectively ensuring the stable and reliable power supply of the elevator car 2. When the elevator car 2 is running, the cleaning brush strip 206 provided in the protective shell 202 can clean the dust attached to the surface of the wireless power supply rail 101, avoiding the wireless power supply rail 101 from being affected by the adhesion or dust on its surface and affecting its own heat dissipation effect, further ensuring the stable and reliable power supply of the elevator car 2.

[0023] The power supply principle of the elevator's contactless power supply is mainly realized by using the electric field coupling wireless power supply principle. The electric field coupling wireless power supply technology uses the electric field to transmit electric energy from the transmitting end (i.e., the wireless power supply guide 101) to the receiving end (i.e., the wireless power supply 201). This technology can realize wireless power supply within a certain distance, and has high transmission efficiency, which can avoid problems such as poor contact and electric sparks that may occur in traditional contact power supply methods.

[0024] Example 2:

[0025] Reference Figures 1-4 , a floor power station type contactless elevator car power supply device is basically the same as Example 1, and further: the through-holes 203 are symmetrically opened on the upper and lower sides of the protective shell 202. By symmetrically opening two groups of through-holes 203 on the protective shell 202, a fan 204 can be set on the upper and lower sides of the wireless power supply 201. When the fan 204 is started to dissipate heat to the wireless power supply 201 and the wireless power supply guide 101, convection can be used to blow air to dissipate heat, thereby avoiding damage due to excessive temperature, further ensuring the stable and reliable power supply of the elevator car 2.

[0026] Two electrostatic dust collecting plates 207 are symmetrically arranged on both sides of the protective shell 202. Through the arrangement of the electrostatic dust collecting plates 207, after the fan 204 blows away the dust on the wireless power supply guide rail 101 with the cleaning brush 206, the dust floating in the elevator shaft 1 will be captured by the electrostatic dust collecting plates 207 and adsorbed on the electrostatic dust collecting plates 207, thereby preventing the cleaned dust from adhering to the wireless power supply guide rail 101 again, effectively improving the dust cleaning effect of the wireless power supply guide rail 101.

[0027] Example 3:

[0028] Reference Figures 1-4, a floor power station type contactless elevator car power supply device, which is basically the same as Example 2, and further: the electrostatic dust absorbing plate 207 is connected to the protective shell 202 by a telescopic component for upward and downward movement, and a plurality of scrapers 208 are fixedly connected to the protective shell 202 on one side close to the dust absorbing surface of the electrostatic dust absorbing plate 207 at equal intervals, and the scrapers 208 slide against the dust absorbing surface of the electrostatic dust absorbing plate 207.

[0029] The telescopic assembly includes a fixed plate 209, a vertical rod 2010 and a telescopic spring 2011. The fixed plate 209 is symmetrically fixedly connected to the upper and lower sides of the protective shell 202 near the electrostatic dust absorption plate 207. The vertical rod 2010 is equidistantly fixedly connected between the two fixed plates 209 on the same side. The electrostatic dust absorption plate 207 is slidingly connected to the vertical rod 2010. The telescopic spring 2011 is symmetrically sleeved on the vertical rod 2010 in the middle. The two ends of the telescopic spring 2011 are respectively connected to the fixed plate 209 and the electrostatic dust absorption plate 207.

[0030] When the elevator car 2 moves up and down in the elevator shaft 1, the electrostatic dust collecting plate 207 will swing up and down under the drive of the elevator car 2 and with the cooperation of the vertical rod 2010 and the telescopic spring 2011. Then the dust adsorbed on the surface of the electrostatic dust collecting plate 207 will be scraped to the upper and lower sides of the electrostatic dust collecting plate 207 by the scraper 208, so that the cleaning brush strip 206 can clean the dust on the wireless power supply guide rail 101, and the electrostatic dust collecting plate 207 can capture it, avoiding the electrostatic dust collecting plate 207 The surface of the dust is affected by a lot of dust attached to the subsequent dust capturing effect, effectively ensuring the electrostatic dust collecting plate 207's ability to continuously capture dust.

[0031] Example 4:

[0032] Reference Figures 1-4 , a floor power station type contactless elevator car power supply device, which is basically the same as Example 3, and further: the cleaning brush strip 206 and the scraper 208 are respectively an insulating rubber strip and an insulating rubber plate. By making the cleaning brush strip 206 and the scraper 208 both of which are made of insulating materials, the insulation performance of the cleaning brush strip 206 and the scraper 208 can be improved, thereby preventing some dust from adhering to the cleaning brush strip 206 and the scraper 208 after the dust is swept down, thereby affecting the dust cleaning effect.
