The invention discloses a photovoltaic power generation early warning device arranged on a high slope, which belongs to the field of photovoltaics. A photovoltaic power generation early warning device installed on a high slope includes a slope and a control processor. Warning boxes and uniform distribution are installed on the slope. A plurality of photovoltaic panel groups, the photovoltaic panel group includes a plurality of photovoltaic panels arranged in the vertical direction, the rear end of the photovoltaic panel is fixedly connected with a positioning point, and the warning box is located above the plurality of photovoltaic panel groups. The installation slot and multiple through holes corresponding to the photovoltaic panel group realize the combination of the LED light and the warning column, which can not only quickly find the location of the loose photovoltaic panel, but also reduce the cost, effectively realize the warning to the user, and is easy to use The operator can deal with the loose problem in time, reduce the sliding damage of photovoltaic panels, and effectively protect the personal safety of the surrounding personnel. At the same time, the loose photovoltaic panels are not easy to cause collision damage to the photovoltaic panels installed around, which greatly reduces economic losses.

The invention relates to the field of electronics, and particularly relates to a multifunctional earphone cable with functions of falling prevention and emergency falling. The multifunctional earphonecable comprises a plug component, a control component and a branch component. According to the device, when the earphone cable is slightly pulled, the earphone cable is slightly lengthened so as to take a certain buffer effect, and particularly when a mobile phone connected with an earphone falls off, the earphone cable can take an effect of preventing the mobile phone from falling off or reducing falling damage; the device can be automatically broken from multiple positions when the earphone cable is strongly pulled so as to prevent accidental injuries of the earphone cable to the body of auser, such as throat cutting and the like, and after being broken, the device can be manually plugged in to implement recovery; the plug component of the device also has functions of an adaptor when achieving the functions of preventing falling and emergency falling, so that the earphone can be matched with interfaces such as a Type-C interface and the like; and the earphone cable can be broken from the middle, and a plug at the broken position is a common earphone plug, and thus, when a demand for the length of the earphone cable is relatively low, inconvenience brought to the user by the excessively long earphone cable can be eliminated.

The invention provides a self-locking device of lifting hooks. A collision block and a self-locking part are arranged on the self-locking device, the collision block is fixedly connected with a first connecting shaft and a third connecting shaft, and a second connecting shaft slides on the collision block; when the collision block moves to the lowest position downwards, the lifting hooks are opened, and when the collision block moves to the highest position upwards, the lifting hooks are closed; when the collision block moves to the lowest position or the highest position, the self-locking portion forms self locking, and the opening or closing state of the lifting hooks is kept; and the device has the beneficial effects of being simple in structure, ingenious in design, convenient to operate, safe to use, capable of achieving automatic loading and unloading and improving efficiency and the like.
