Background
Because ultraviolet has requirements on the distance, in order to realize better disinfection effect, the lifting type ultraviolet disinfection lamp is designed scientifically, can be put down during disinfection, has less influence on the use of the space at the lower part after being lifted after disinfection, the lifted position is detected by the lamp bracket detection sensor, when the lamp bracket detection sensor detects the lamp bracket, a signal is sent to the controller, the controller controls the motor to stop, the initial simple lifting type ultraviolet disinfection lamp adopts the motor to drive a scroll to rotate, two pull wires are connected on the ultraviolet lamp bracket, the pull wires are wound on the scroll, cables for supplying power to the ultraviolet lamp are also wound on the scroll, the lifting of the ultraviolet lamp is realized by the rotation of the scroll in different directions, the pull wires are easy to be stacked and disordered during the process of long-term use and repeated winding, thereby the lifting of the pull wires at two ends and the lifting of the cables are asynchronous lifting, can lead to the lift unstable, under the asynchronous serious condition of stay cord and cable, cable and lamp stand junction can be torn open, lead to the trouble, in order to overcome this kind of defect, some over-and-under type ultraviolet ray disinfection lamp have fixed practicing grade two winding wheels on the spool, the belt is convoluteed on the winding wheel, ultraviolet lamp bracket connects at the belt lower extreme, this kind of mode can better synchronous receive and release at lift in-process belt, the unstable problem of lift has basically been overcome, but in use because the cable is unable to put with the comparatively regular roll of belt when receiving and releasing like, so still there is the asynchronous problem of belt and cable under this kind of mode, under asynchronous serious condition, the cable can bear great pulling force, the node of cable and lamps and lanterns or cable itself can break off, lead to ultraviolet ray disinfection lamp to break down.
Disclosure of Invention
An object of the utility model is to overcome the above-mentioned problem that present over-and-under type ultraviolet ray disinfection lamp exists, provide an over-and-under type ultraviolet ray disinfection lamp cable protection mechanism.
In order to realize the purpose of the utility model, the following technical proposal is adopted: over-and-under type ultraviolet ray disinfection lamp cable protection mechanism, including the drive box, the drive box in install the motor, spool fixed connection is on the output shaft of motor, two winding wheels of fixedly connected with on the spool, the one end fixed connection of belt is on the winding wheel, other end fixed connection is on the lighting fixture, the cable wheel of still fixed connection on the spool, the electricity is connected for the ultraviolet lamp power supply between cable and the ultraviolet ray disinfection lamp, installs lighting fixture detection sensor on the drive box, motor, lighting fixture detection sensor all are connected to the controller, install the shell fragment on the lighting fixture up end, shell fragment one end fixed connection on the lighting fixture up end, the other end be the free end, the cable is connected to the ultraviolet ray disinfection lamp through being connected to under the shell fragment.
Further, the method comprises the following steps of; the lamp holder is fixedly connected with a travel switch, a contact of the travel switch is positioned above the elastic sheet, and the travel switch is connected in series in a power supply line of the motor.
Further, the method comprises the following steps of; the travel switch is fixedly arranged on a stud in a penetrating mode, positioning nuts are screwed on the studs above and below the travel switch, and the studs are fixedly connected to the lamp holder.
Further, the method comprises the following steps of; the end part of the free end is a smooth surface.
Further, the method comprises the following steps of; and the bottom surface of the driving box above the elastic sheet and the travel switch is provided with a corresponding long hole, and the long hole covers the elastic sheet and the travel switch.
The utility model discloses an actively beneficial technological effect lies in: this mechanism can effectually prevent the ultraviolet ray disinfection lamp trouble that the fracture leads to when the in-process cable of going up and down is not synchronous by tensile.
