Description

Technical Field

[0001] The utility model relates to the technical field of emergency power supply vehicles, in particular to a low-voltage emergency power supply vehicle access device with a function of preventing misoperation. Background Art

[0002] Emergency power supply vehicle, also known as power generation vehicle, power supply vehicle, etc., is a special vehicle that integrates mobility, power generation and emergency functions. Emergency power supply vehicle is usually equipped with diesel generator, control and operating system, outgoing cable system, etc., which can provide temporary power support for disaster relief, temporary construction, on-site maintenance and other emergencies. These vehicles are mainly used in electricity, communications, conferences, engineering rescue and military places as mobile emergency backup power sources.

[0003] Emergency power supply vehicles are equipped with a large number of power ports to meet the needs of supplying power to multiple devices. However, in actual operation, the power plug is often plugged into the wrong power port. Since different power plugs require different currents and voltages for electrical equipment, wrong plugging can easily cause equipment damage and may also have an adverse effect on the emergency power supply vehicle. In order to avoid this misoperation incident, we have invented a low-voltage emergency power supply vehicle access device with a misoperation prevention function. Utility Model Content

[0004] The purpose of the utility model is to provide a low-voltage emergency power supply vehicle access device with a function of preventing misoperation, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A low-voltage emergency power supply vehicle access device with a function of preventing misoperation, comprising an emergency power supply box and a power plug, wherein a slot is provided on the emergency power supply box, a power connection port is provided in the slot, and mis-insertion prevention holes are provided around the power connection port in the slot, a cover plate is installed on the power plug, and a mis-insertion prevention rod matching the corresponding slot is installed on one end surface of the cover plate facing the slot, a plug coloring area is provided on the surface of the power plug, and a slot coloring area is provided around the slot on the emergency power supply box.

[0007] As a further solution of the utility model: the color of each plug coloring area is different, the color of each slot coloring area is different, and the plug coloring areas correspond to the slot coloring areas one by one.

[0008] As a further solution of the utility model: a waterproof cover is arranged outside the slot, a hinge is installed on the waterproof cover, and the waterproof cover is connected to the emergency power supply box through the hinge.

[0009] As a further solution of the utility model: the waterproof cover is a transparent cover, and a handle is installed on the waterproof cover.

[0010] As a further solution of the utility model: the number of anti-mis-insertion holes in each of the slots is not equal, and the number of anti-mis-insertion rods on each of the cover plates is not equal.

[0011] As a further solution of the utility model: the number of the anti-mis-insertion holes around each power connection port is equal to the number of the anti-mis-insertion rods around the corresponding power connection plug.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides anti-misinsertion sockets and anti-misinsertion rods, and each corresponding power port and power plug are respectively provided with an equal number of anti-misinsertion sockets and anti-misinsertion rods. When the power plug is inserted into a power port that is not compatible with it, the number and position of the anti-misinsertion rods and the anti-misinsertion sockets cannot match, so that the power plug cannot be inserted into the power port that is not compatible with it, thereby effectively avoiding errors when the low-voltage emergency power supply vehicle is connected, and achieving the purpose of preventing misoperation.

[0014] 2. The utility model provides a slot coloring area and a plug coloring area on the outside of the corresponding power connection port and the outside of the power connection plug, respectively, and by painting the corresponding slot coloring area and the plug coloring area with the same color, it can help the operator quickly identify the corresponding port that is compatible with the plug when the low-voltage emergency power supply vehicle is connected to power, thereby improving the access efficiency and reducing the possibility of wrong connection.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In an embodiment of the utility model, a low-voltage emergency power supply vehicle access device with a function of preventing misoperation includes an emergency power supply box 1 and a power plug 5. A slot 2 is provided on the emergency power supply box 1, and a power port 3 is provided in the slot 2. An anti-misplugging hole 4 is provided around the power port 3 in the slot 2, and a cover plate 6 is installed on the power plug 5. An anti-misplugging rod 7 matching the corresponding slot 2 is installed on the end surface of the cover plate 6 facing the slot 2. The number of anti-misplugging holes 4 in each slot 2 is not equal, and the number of anti-misplugging rods 7 on each cover plate 6 is not equal. The number of anti-misplugging holes 4 around each power port 3 is equal to the number of anti-misplugging rods 7 around the corresponding power plug 5. This design can prevent the unmatched power ports 3 from contacting smoothly with the power plug 5.

[0021] See also Figure 1-2 A plug coloring area 9 is provided on the surface of the power plug 5, and a slot coloring area 10 is provided around the slot 2 on the emergency power supply box 1. The color of each plug coloring area 9 is different, and the color of each slot coloring area 10 is different. The plug coloring area 9 corresponds to the slot coloring area 10 one by one.

[0022] See also Figure 2-3 A waterproof cover 11 is provided on the outside of the slot 2, and a hinge 12 is installed on the waterproof cover 11. The waterproof cover 11 is connected to the emergency power supply box 1 through the hinge 12. The waterproof cover 11 is a transparent cover. The transparent design allows personnel to see the slot coloring area 10 conveniently, so that personnel can identify the correct power connection port 3 according to the color. A handle 13 is installed on the waterproof cover 11, and the setting of the handle 13 allows personnel to open the waterproof cover 11 conveniently.

[0023] It should be noted that the emergency power supply box 1 is installed on the emergency power supply vehicle, and the power plug 5 is connected to an external power line 8 .

[0024] The working principle of the utility model is:

[0025] During use, when a person inserts the power plug 5 into the corresponding power port 3, he or she can quickly find the corresponding power port 3 and fully connect it according to the color of the plug painted area 9 on the power plug 5 and the color of the slot painted area 10 of the slot 2 where the power port 3 is located. When a person mistakenly inserts the power plug 5 into a power port 3 that does not match it, the anti-misinsertion plug rod 7 on the power plug 5 cannot be matched with the anti-misinsertion plug hole 4 around the power port 3, thereby causing the power plug 5 to be unable to be inserted into the power port 3, thereby effectively avoiding the possibility of misinsertion and achieving the effect of preventing misoperation.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
