Description

Low-voltage direct-current explosion-proof distribution box for ship cabin Technical Field The invention relates to the technical field of ship distribution boxes, in particular to a low-voltage direct-current explosion-proof distribution box for a ship cabin. Background The power distribution cabinet is a generic name of a motor control center, and an electrical control switch is usually installed in the power distribution cabinet, and the electrical switch is mainly a toggle switch, such as an air switch. For the purpose of centralized control, the electric switches installed in the same power distribution cabinet are often more in number and closer in distance, meanwhile, the types of the switches are almost unified and mainly toggle switches, and the operation modes of the switches are highly similar, so that the phenomenon of mistakenly touching the switches is unavoidable when the switches are opened or closed. Particularly for the distribution box applied to the ship, as the ship is rocked along with the running, the body of the personnel on the ship can also rock, so that the risk of false touch to the electrical switch is greatly increased when the operator on the ship operates the electrical switch in the distribution box. Although existing ship power distribution cabinets may be provided with handles for the operator to grasp to reduce body sway, the hands used by the operator to hold these handles are not the hands actually used by the operator to operate the appliance switch. The operator's hand for operating the electric switch is still not supported, and thus, when the ship is swayed to cause the body of the operator to be swayed, the operator may still miss the electric switch to cause unnecessary accidents. Indeed, in the prior art, the technical scheme of the device for preventing the false touch of the scram button and the power distribution cabinet for preventing the false touch also exists as the patent number is CN206322611U, and the patent name is scram button, and the power distribution cabinet with the false touch preventing function is disclosed. However, the power distribution cabinet in the scheme has the following defects that although the whole device has the function of preventing false touch, the false touch is avoided by only arranging the scram button in the groove box, and the problem of false touch is difficult to effectively solve, so that the risk of accidents caused by false touch of electric appliances still exists. Disclosure of Invention The invention aims to provide a low-voltage direct-current explosion-proof power distribution box for a ship cabin, which solves the problem that the existing ship power distribution box is difficult to stably support the hand of an operator for operating an electric switch, so that the risk of misoperation of the electric switch due to ship shaking is reduced. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a low-voltage direct current explosion-proof block terminal in boats and ships cabin, includes the main tank body, be provided with the installation room that is used for installing electrical switch in the main tank body, fixed mounting has the handle on the main tank body, be provided with strutting arrangement in the main tank body, be provided with the bracing piece that is used for supporting the hand of operating personnel operation electrical switch in the strutting arrangement, be provided with operating means in the main tank body, be provided with in the operating means along the bracing piece motion and be used for operating electrical switch's operation stick. Based on the scheme, when an operator operates the electric switch in the installation chamber of the main box body, the two hands of the operator can respectively grasp the handle and the support rod, so that the two hands of the operator can be supported, and the influence of the shaking of the ship on the body of the operator is reduced. Meanwhile, an operator can operate the electric switch in the installation chamber by means of the operating rod in the operating device under the support of the supporting device by holding the supporting rod by the operator, and further, the operations such as inspection, maintenance and circuit adjustment can be completed smoothly. Therefore, the invention can provide stable support for the hand of the operator operating the switch when the operator operates the electric switch under the condition of not interfering the normal work of the operator by using the supporting device and the operating device, thereby reducing the risk of the operator from mistakenly shocking the electric switch due to the shaking of the ship. Specifically, the supporting device can comprise a mounting cavity arranged in the main box body, two sliding grooves are symmetrically formed in the side wall of the mounting cavity, supporting rods are movably mounted in
