Problems solved by technology

A leakage protector must be installed in the switch box. The installation of the leakage protector also has the requirement of vertical installation and the installation inclination angle should not exceed a certain value. Otherwise, there will be a certain probability that the leakage protector will not trip when the leakage occurs, thus causing serious harm to the human body. Causes non-negligible damage. If the distribution box in the open air in rainy days is dumped, it will pose a greater safety hazard
Even if the construction site is strictly in accordance with the requirements of the specification, there are still uncertain factors that cause the equipment with poor stability such as switch boxes to fall to the ground or tilt
[0003] Therefore there is above-mentioned various inconvenience and problem in the distribution box of known construction site

Embodiment 1

[0040] The distribution box with anti-fall detection equipment of the present invention includes an external assembly box and an internal circuit.

[0041] see now Figure 1-3 , figure 1 It is a schematic diagram of the first structure of the distribution box according to the embodiment of the present invention, figure 2 It is a schematic diagram of the second structure of the distribution box according to the embodiment of the present invention, image 3 It is a schematic diagram of the third structure of the distribution box according to the embodiment of the present invention. As shown in the figure, the external assembly box includes a box body, an internal module and an audible and visual alarm. The box body is U-shaped. The upper part is provided with an audible and visual alarm 1, and two fastening bolt holes 2 for main power wiring arranged up and down are arranged in the recess on the lower side of the audible and visual alarm panel, and the side of the audible an...

Embodiment 2

[0045] A method for manufacturing a distribution box with an anti-fall detection device includes the following steps:

[0046] a. Production of external box

[0047] The external cabinet is made of aluminum alloy plate. During the production of the external cabinet, attention should be paid to the size of the external cabinet. There must be enough space inside to install the mercury switch, the amplifier circuit, the drive circuit module and the components of the output drive module circuit board; the cabinet must be There are wiring holes corresponding to the distribution box for normal wiring;

[0048] Figure 7 It is a diagram of the output driving module of the embodiment of the present invention.

[0049] b. Internal circuit board production

[0050] ①According to the schematic diagram of the function design of the distribution box of the anti-rewind and anti-fall detection equipment, in the schematic diagram, the electrical performance of the components of each module...

Embodiment 3

[0058] The use method of the distribution box with anti-fall detection equipment of the present invention is as follows:

[0059] Install the prepared distribution box with anti-falling detection equipment in the third-level distribution box, connect the main power inlet terminal to the external line, and then connect to the second-level distribution box, and connect the middle part to the air switch and distribution box. It can be put into normal operation after the wiring is completed.

[0060] The circuit converts the AC220V voltage into DC12V*1A voltage through the converter for the main circuit. When the distribution box falls to the ground, the mercury switch will be closed at this time, the TLP521 will be energized at this time, and the shunt release will be normally closed and the electric shock will open at this time, the circuit through the sound and light alarm in the circuit will be energized at this time, and an alarm will be issued. Remind the on-site staff to c...

Abstract

An anti-tilting detection device-equipped power distribution box is disclosed and comprises an external assembling box and an internal circuit. The anti-tilting detection device-equipped power distribution box is characterized in that the external assembling box comprises a box body, an internal module and an audible-visual alarm device; the box body is shaped like U, one branch end is a wide and thick box end while another branch end is a narrow and thin box end, and an upper part of the wide and thick box end is provided with the audible-visual alarm device (1); the internal circuit comprises an amplification circuit having a mercury switch, a drive circuit module and an output driving module; the amplification circuit, the drive circuit module and the output driving module are used for forming a circuit board installed in the box body. The anti-tilting detection device-equipped power distribution box and the manufacturing method therefor disclosed in the invention are advantageous in that an installation position of the power distribution box can be automatically detected, personal safety can be ensured, alarms can be sent out when the power distribution box is not property positioned, and the power distribution box can be powered on when being positioned properly.

Description

technical field [0001] The invention relates to a distribution box used on a construction site, in particular to a distribution box with an anti-fall detection device and a manufacturing method thereof. Background technique [0002] The power distribution system on the construction site should be equipped with indoor main distribution panels and outdoor distribution boxes or outdoor main distribution boxes, distribution boxes, and switch boxes to implement three-level power distribution. The distribution box and switch box should be installed correctly and firmly, and the mobile box should be installed on a solid support. Various electrical appliances in the distribution box and switch box should be fastened to the mounting plate according to the specified position, and must not be skewed or loose. A leakage protector must be installed in the switch box. The installation of the leakage protector also has the requirement of vertical installation and the installation inclinat...
