The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.

According to one aspect of the invention, a ventilation and heat dissipation roof is provided for protecting equipment disposed on the roof of a rail vehicle and for ventilating the roof of the rail vehicle for heat dissipation.

Fig. 1 shows a top view of a ventilation and heat dissipation top cover, and fig. 2 shows a rear view of the ventilation and heat dissipation top cover shown in fig. 1. The concept of the invention is explained below in connection with fig. 1 and 2.

The ventilation and heat dissipation top cover comprises a top cover main body 100 and a fan. As can be seen from the rear view of fig. 2, a fan mounting plate 101 is provided at the rear end of the top cover main body 100, and a reserved space for mounting a fan is provided on the fan mounting plate 101 for mounting the fan.

Most rail transit vehicles can run in two directions, and in order to meet the heat dissipation and ventilation requirements of the top of the rail transit vehicles in the two-way running process, the fans arranged on the ventilation and heat dissipation top covers can comprise a fan 102 for exhausting air in the forward direction and a fan 103 for sucking air in the reverse direction.

When the rail transit vehicle is driving in the positive direction, the direction of travel is by the rear end of ventilation heat dissipation top cap pointing to the front end promptly, and the wind current at rail transit vehicle top flows to the rear end by its front end. The wind flows through the top of the rail transit vehicle and exchanges heat with the equipment arranged on the top to become hot wind, and the fan 102 operates to discharge the hot wind in the top of the rail transit vehicle outwards from the rear end, while the fan 103 is turned off.

When the rail transit vehicle is stationary, fan 102 operates to expel hot air from the rear end outwardly within the roof of the rail transit vehicle, while fan 103 is turned off.

When the rail transit vehicle runs in a reverse direction, namely the running direction is directed from the front end to the rear end of the ventilation and heat dissipation roof, the fan 103 operates to suck cold air outside the rear end into the top of the rail transit vehicle for cooling equipment arranged on the top of the rail transit vehicle, and meanwhile, the fan 102 is turned off.

Further, in order to improve the heat dissipation and air discharge requirements of the ventilation and heat dissipation top cover, the top cover main body 100 is provided with a vent hole 104 through which the air expansion and hot air during the traveling process can be discharged.

It is understood that the vent holes 104 may be of any regular or irregular geometry. However, when the number of the vent holes 104 on the roof main body 100 is too large or the aperture is too large, rainwater may easily enter into the roof of the rail transit vehicle, and therefore the aperture of the vent holes 104 needs to be reduced as much as possible while satisfying the ventilation requirement, and the number is not too large. Preferably, the vent 104 may be provided as an elongated waist-shaped vent as shown in FIG. 1. More preferably, the vent hole 104 may be provided at a position on the cover main body 100 corresponding to a position where no electrical equipment is provided on the roof of the rail transit vehicle, so that a problem that the equipment may be damaged by rainwater may be avoided.

Further, as shown in a rear view of fig. 2, both left and right ends of the roof main body 100 include eaves 105 extending upward, and when installed, the eaves 105 are fixedly coupled to the top of the rail transit vehicle. Most of the roof main body 100 is deposited on the top of the rail transit vehicle to a certain extent, so that severe impact on the ventilation and heat dissipation roof caused by rapid operation of the vehicle is avoided.

Furthermore, a platform structure 106 is arranged on the eaves 105, and the bottom of the platform structure 106 is flat so as to be fixedly connected with the top of the rail transit vehicle. The bottom of the sinking platform structure 106 may be provided with bolt mounting holes to be fixedly connected with skirts or brackets provided on the top of the rail transit vehicle by bolts.

In this connection, the sinking platform structure 106 may be a plurality of structures distributed as shown in fig. 1, and the peripheral edge of the sinking platform structure 106 is not much different from the overall thickness of the top cover main body 100 to improve the strength of the top cover main body 100.

Preferably, as shown in fig. 2, the longitudinal section of the roof main body 100 is arched to increase the longitudinal bearing force of the ventilation and heat dissipation cover plate, i.e. the pressing force of the rail transit train on the ventilation and heat dissipation cover plate in a turning or other situation.

Further, the top cover main body 100 is further provided with a reinforcing rib 107 to ensure the strength and rigidity of the ventilation and heat dissipation top cover.

The number of the reinforcing ribs 107 can be set according to the rigidity requirement of the ventilation and heat dissipation top cover. And a certain number of transverse reinforcing ribs and longitudinal reinforcing ribs are respectively arranged according to the requirements of the ventilation and heat dissipation top cover on the transverse rigidity and the longitudinal rigidity. As shown by the dotted lines in fig. 1, the top cover main body 100 is provided with 4 lateral reinforcing ribs and 4 lateral reinforcing ribs.

Further, to facilitate the installation and removal of the ventilating and heat dissipating roof of the rail transit vehicle, the upper surface of the roof main body 100 may be provided with a plurality of hanger bolts 108. When the ventilation and heat dissipation roof is installed on or detached from the top of the rail transit vehicle, the roof main body 100 may be lifted and moved to or removed from the top of the rail transit vehicle by a lifting device.

It is understood that the upper surface of the top cover main body 100 includes a peripheral edge portion of the top cover main body 100, etc. exposed to the outside for hanging.

Further, the top cover main body 100 is integrally formed by a light-weight and high-strength material, such as a glass fiber or a carbon fiber material. The fan mounting plate 101 may be embedded in a glass fiber or carbon fiber material to be integrally formed.

Fans

102 and 103 may be mounted on the top cover body in a subsequent assembly process.

In another embodiment, as shown in fig. 3, the ventilation and heat dissipation top cover includes a top cover body 200 and a blower 202. A fan mounting plate (not shown) is arranged at the rear end of the top cover main body 200, and a reserved position for mounting a fan is arranged on the fan mounting plate and used for mounting the fan.

Most rail transit vehicles can run in two directions, in order to meet the heat dissipation and ventilation requirements of the top of the rail transit vehicles in the two-way running process, the fan 202 arranged on the ventilation and heat dissipation top cover is an integrated fan supporting two-way air exhaust, the integrated fan rotates in the forward direction to exhaust air in the forward direction, and rotates in the reverse direction to exhaust air in the reverse direction.

When the rail transit vehicle is driving in the forward direction, namely the direction of driving is from the rear end of ventilation heat dissipation top cap to the front end, and the wind current at the top of the rail transit vehicle flows from its front end to the rear end. The wind flows through the top of the rail transit vehicle and exchanges heat with the equipment arranged on the top to become hot wind, and the fan 202 rotates in the positive direction to discharge the hot wind in the top of the rail transit vehicle outwards from the rear end.

When the rail transit vehicle is stationary, the fan 202 is rotating in a forward direction to expel hot air from the rear end outwardly within the roof of the rail transit vehicle.

When the rail transit vehicle runs in a reverse direction, i.e., the running direction is from the front end to the rear end of the ventilation and heat dissipation roof, the fan 202 rotates in a reverse direction to suck cold air outside the rear end into the top of the rail transit vehicle for cooling the equipment arranged on the top of the rail transit vehicle.

It can be understood that the rear view of the top cover main body 200 is similar to that of fig. 2, and the only difference is that the reserved positions for installing the fans are different on the fan installation plate, and the installed fans are different and are not shown.

Furthermore, in order to improve the heat dissipation and air exhaust requirements of the ventilation and heat dissipation top cover, the top cover main body 200 is provided with a vent hole 204 through which the air expansion and hot air in the traveling process can be exhausted.

It is understood that the vent 204 may be of any regular or irregular geometry. However, when the number of the vent holes 204 on the roof main body 200 is too large or the aperture is too large, rainwater may easily enter into the roof of the rail transit vehicle, and therefore the aperture of the vent holes 204 needs to be reduced as much as possible while satisfying the ventilation requirement, and the number of the vent holes is not too large. Preferably, the vent 204 may be provided as an elongated waist-shaped vent as shown in FIG. 3. More preferably, the vent hole 204 may be provided at a position on the cover main body 200 corresponding to a position where no electrical equipment is provided on the roof of the rail transit vehicle, so that a problem that the equipment may be damaged by rainwater may be avoided.

Further, both ends of the roof main body 200 include an upwardly extending eaves 205, and when installed, the eaves 205 are fixedly coupled to the top of the rail transit vehicle. Most of the roof main body 200 is deposited on the top of the rail transit vehicle to a certain extent, so that severe impact on the ventilation and heat dissipation roof caused by rapid operation of the vehicle is avoided.

Furthermore, a platform 206 is disposed on the eaves 205, and the bottom of the platform 206 is flat to facilitate the fixed connection with the top of the rail transit vehicle. The bottom of the sinking platform structure 206 may be provided with bolt mounting holes to be fixedly connected with skirts or brackets provided on the top of the rail transit vehicle by bolts.

In this connection, the platform structure 206 may be a plurality of structures distributed as shown in fig. 3, and the peripheral edge of the platform structure 206 is not much different from the overall thickness of the top cover main body 200 to improve the strength of the top cover main body 200.

Preferably, the longitudinal section of the top cover main body 300 is arched to increase the longitudinal bearing force of the ventilation and heat dissipation cover plate, i.e. the pressing force of the rail transit train on the ventilation and heat dissipation cover plate in a turning or other situations.

Further, the top cover main body 200 is further provided with a reinforcing rib 207 to ensure the strength and rigidity of the ventilation and heat dissipation top cover.

The number of the reinforcing ribs 207 can be set according to the rigidity requirement of the ventilation and heat dissipation top cover. And a certain number of transverse reinforcing ribs and longitudinal reinforcing ribs are respectively arranged according to the requirements of the ventilation and heat dissipation top cover on the transverse rigidity and the longitudinal rigidity. As shown by the dotted lines in fig. 3, the top cover main body 200 is provided with 4 lateral reinforcing ribs and 4 lateral reinforcing ribs.

Further, to facilitate the installation and removal of the ventilating and heat dissipating roof of the rail transit vehicle, the upper surface of the roof main body 200 may be provided with a plurality of hanger bolts 208. When the ventilation and heat dissipation roof is installed on or detached from the top of the rail transit vehicle, the roof main body 200 may be lifted and moved to or removed from the top of the rail transit vehicle by a lifting device.

It is understood that the upper surface of the top cover main body 200 includes a peripheral edge portion of the top cover main body 200, etc. exposed to the outside for hanging.

Further, the top cover main body 200 is integrally formed by a light-weight and high-strength material, such as a glass fiber or a carbon fiber material. The fan mounting plate 201 may be embedded in a glass fiber or carbon fiber material to be integrally formed. The fans 202 and 203 may be mounted on the top cover body in a subsequent assembly process.
