Description

Technical Field

[0001] This utility model belongs to the field of rail transit vehicle technology, and in particular relates to an under-suspension power supply box for rail transit vehicles. Background Technology

[0002] Rail transit vehicles are high-speed, high-capacity, electrically powered rail transit systems built in cities. Trains run on fully enclosed lines. Lines in the central urban area are generally located in underground tunnels, while lines outside the central urban area are generally located on viaducts or at ground level.

[0003] Rail transit vehicles are mainly powered by two methods: track power supply and overhead cable. In order to ensure the normal operation of various electrical equipment, some routine periodic live inspections and maintenance are required. To achieve this, rail transit vehicles are equipped with dedicated maintenance power boxes. The power boxes on the ground need to be waterproof, and the power boxes in tunnels need to be moisture-proof. This is because the internal components of the power box will generate heat when it is running. If the air inside the power box is humid, it will cause a cold bridge effect on the internal components, which will easily cause damage. Therefore, it is necessary to install a power box that is suspended under the rail transit vehicle to avoid the cold bridge effect between the humid air inside the power box and the heat-generating internal components, which will damage the components. Utility Model Content

[0004] The purpose of this invention is to provide a suspended power supply box for rail transit vehicles. The combined use of Z-shaped grooves, oblique grooves, and L-shaped plates effectively prevents liquid from entering the inner cavity of the power supply box body. The blowing device can keep the inner cavity of the power supply box body ventilated and dry, effectively avoiding the cold bridge effect between the humid air inside the power supply box and its heat-generating internal components, which would damage the components, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A power supply box suspended under a rail transit vehicle includes a power supply box body and a box door. Multiple components are fixedly installed on the rear side of the inner cavity of the power supply box body. A rectangular groove is opened at the bottom of the inner cavity of the power supply box body. A blower is fixedly installed at the top of the rectangular groove cavity. Multiple Z-shaped grooves are opened on both sides of the power supply box body. An oblique groove is opened at the bottom of the Z-shaped groove on both sides of the inner cavity of the power supply box body. L-shaped plates are provided on both sides of the inner cavity of the power supply box body. Extension plates are fixedly connected to the front and rear of the L-shaped plates. Multiple bolts are threaded to the opposite side of the two extension plates. The bolts penetrate into the interior of the power supply box body.

[0006] Preferably, the power supply box body and the box door are connected by a hinge.

[0007] Preferably, a connecting strip is fixedly connected to the bottom of the inner cavity of the L-shaped plate, and the bottom of the connecting strip is in contact with the bottom of the inclined groove cavity.

[0020] In the following description, embodiments of the under-suspension power supply box for rail transit vehicles of the present invention will be described with reference to the accompanying drawings.

[0021] Example 1:

[0022] Figure 1-4 This invention illustrates an embodiment of a suspended power supply box for a rail transit vehicle, comprising a power supply box body 1 and a door 2. Multiple components 4 are fixedly installed on the rear side of the inner cavity of the power supply box body 1. A rectangular groove 5 is formed at the bottom of the inner cavity of the power supply box body 1, and a blower 6 is fixedly installed at the top of the rectangular groove 5. Multiple Z-shaped grooves 7 are formed on both sides of the power supply box body 1. Inclined grooves 8 are formed on both sides of the inner cavity of the power supply box body 1, located at the bottom of the Z-shaped grooves 7. L-shaped plates 9 are provided on both sides of the inner cavity of the power supply box body 1. A connecting strip 10 is fixedly connected to the bottom of the inner cavity of the L-shaped plate 9, and the bottom of the connecting strip 10 is connected to the cavity of the inclined groove 8. The bottom of the two parts fit together. The connecting strip 10 connects the cavity of the oblique groove 8 and the inner cavity of the L-shaped plate 9, preventing liquid from flowing into the inner cavity of the power box body 1 along the inner wall if it enters the inner cavity of the L-shaped plate 9. Extension plates 11 are fixedly connected to the front and back of the L-shaped plate 9. Multiple bolts 12 are threadedly connected to the opposite side of the two extension plates 11. The bolts 12 penetrate into the interior of the power box body 1. Multiple baffles 13 are fixedly connected to both sides of the power box body 1. The positions of the baffles 13 correspond one-to-one with the Z-shaped groove 7 and the oblique groove 8. A dustproof net 14 is fixedly installed at the bottom of the rectangular groove 5 cavity.

[0023] Example 2:

[0024] Figure 1-4 This invention illustrates an embodiment of a rail transit vehicle under-suspension power supply box, comprising a power supply box body 1 and a box door 2. The power supply box body 1 and the box door 2 are connected by a hinge 3. Multiple components 4 are fixedly installed on the rear side of the inner cavity of the power supply box body 1. A rectangular groove 5 is provided at the bottom of the inner cavity of the power supply box body 1. A blower 6 is fixedly installed on the top of the rectangular groove 5. Multiple Z-shaped grooves 7 are provided on both sides of the power supply box body 1. A slanted groove 8 is provided at the bottom of the Z-shaped groove 7 on both sides of the inner cavity of the power supply box body 1. L-shaped plates 9 are provided on both sides of the inner cavity of the power supply box body 1. Extension plates 11 are fixedly connected to the front and rear of the L-shaped plates 9. Multiple bolts 12 are threadedly connected to the opposite side of the two extension plates 11. The bolts 12 penetrate into the interior of the power supply box body 1. Mounting plates 15 are fixedly installed on both the top and bottom sides of the power supply box body 1. A mounting groove 16 is provided on the front side of the mounting plate 15.

[0025] Working Principle: When using this utility model, the user installs the power supply box body 1 in the designated position using the mounting plate 15 and mounting groove 16. If installed on the outside of a rail transit vehicle in a tunnel, the blower 6 is continuously running. When the blower 6 is running, it cools down the running components 4 and ventilates the inner cavity of the power supply box body 1, keeping the inner cavity of the power supply box body 1 dry. If installed on the outside of a ground rail transit vehicle, the blower 6 is also continuously running to ventilate and dry the inner cavity of the power supply box body 1. When there is rain or other liquid, it is first blocked by the baffle 13. Due to the shape of the Z-shaped groove 7 and the oblique groove 8, it is difficult for liquid to enter the inner cavity of the power supply box body 1. If it accidentally enters, it will enter the inner cavity of the L-shaped plate 9. Finally, due to the shape of the oblique groove 8 and its connection with the L-shaped plate 9, the liquid will flow out to the outside of the power supply box body 1 through the oblique groove 8. This achieves the purpose of avoiding the cold bridge effect between the humid air inside the power supply box and the heat-generating internal components, thus preventing damage to the components.

[0026] In summary, the under-suspension power supply box of this rail transit vehicle, through the combined use of Z-shaped groove 7, oblique groove 8 and L-shaped plate 9, allows ventilation in the inner cavity of the power supply box body 1, thereby enabling the components of the power supply box body 1 to dissipate heat naturally and preventing liquid from entering the inner cavity of the power supply box body 1. The setting of the blowing device 6 keeps the inner cavity of the power supply box body 1 ventilated and dry, and also dissipates heat from the components 4. This achieves the purpose of avoiding the cold bridge effect between the humid air inside the power supply box and the heat-generating internal components, which would damage the components.
