Wherein the driving module 1 operates to enable air at the top of the tunnel to enter the first pipeline 2 and then enter the second pipeline 3 through the third pipeline 4, and the air entering the second pipeline 3 is discharged from the end part of the second pipeline 3;
the drive module 1 is arranged on the surface of the road in the tunnel and generates mechanical energy by contact with the running vehicle tyre to drive the fan assembly 5 into operation.
The fan assembly 5 comprises a ducted fan main body 51 installed in the third pipeline 4, a transmission rotating shaft 52 of the ducted fan main body 51 is arranged along the axial direction of the third pipeline 4, the transmission rotating shaft 52 is far away from the ducted fan main body 51 and penetrates through the end portion of the side wall of the third pipeline 4 to be connected with the driving module 1, and the driving module 1 drives the ducted fan main body 51 to rotate through driving the transmission rotating shaft 52 to generate air flow along the axial direction of the third pipeline 4, so that air in the first pipeline 2 enters the second pipeline 3.
The drive module 1 comprises a transmission assembly 10 and a plurality of drive assemblies 20 connected to the transmission assembly 10, the ends of the transmission assembly 10 being connected to a transmission shaft 52.
It is further preferred that the plurality of driving assemblies 20 are disposed on the ground of the tunnel at equal intervals, the driving assemblies 20 are used for generating mechanical energy when being stressed, and the main transmission assembly 10 is used for transmitting the mechanical energy generated by the driving assemblies 20, so as to drive the transmission rotating shaft 52 to rotate.
As shown in fig. 2, the transmission assembly 10 in the present invention includes a transmission shaft main body 101, a plurality of first transmission gears 102 are equally distributed on the transmission shaft main body 101 along the axial direction of the transmission shaft main body 101, a second transmission gear 103 is disposed at the end of the transmission shaft main body 101, and the second transmission gear 103 engages with the transmission shaft 52.
The plurality of driving assemblies 20 are in one-to-one correspondence with and engaged with the plurality of first transmission gears 102.
Further, it is an object of the present invention to construct an energy-efficient ventilation system, which requires the generation of electric energy if the motor is driven by electric energy. The drive assembly 20 includes a crank body 201 and a reduction band plate 202, the reduction band plate 202 is connected to a connecting rod journal 203 of the crank body 201 by a plurality of connecting rods 204, and the other end of the connecting rod 204 away from the connecting rod journal 203 is rotatably connected to the reduction band plate 202.
In order to realize that the speed-reducing band plate 202 is in contact with a running automobile wheel to drive the crankshaft main body 201 to rotate under the force, one side edge of the speed-reducing band plate 202 is rotationally connected with the ground, the bottom of the speed-reducing band plate 202, which is close to the connecting rod 204, is provided with a spring assembly 205, the other end of the spring assembly 205 is fixedly connected with the ground, and the spring assembly 205 is used for supporting the speed-reducing band plate 202 and enabling an included angle to exist between the speed-reducing band plate 202 and the horizontal plane.
Wherein the surface of the deceleration strip 202 compresses the spring assembly 205 and transmits force to the crankshaft main body 201 through the connecting rod 204 to force the crankshaft main body 201 to perform circumferential rotation, thereby driving the transmission shaft main body 101 to perform circumferential rotation through the first transmission gear 102.
The spring assembly 205 is used to restore the angle between the decelerator band plate 202 and the horizontal plane when the decelerator band plate 202 loses external force. In particular, the spring assembly 205 may be a plurality of torsion springs in particular.
In the present invention, in order to obtain the force-driven connecting rod 204 of the speed-reducing band plate 202 and rotate the crank body 201 through the connecting rod, it is obvious that the crank body 201 is made to complete rotation in one cycle in the action cycle of reciprocating rotation within the angle of rotation of the speed-reducing band plate 202 around the connection with the ground, wherein in order to optimize the transmission between the connecting rod 204 and the crank body 201, and when the speed-reducing band plate 202 is driven by the spring assembly 205 completely when the acting force is lost, it is obvious that the connection of the connecting rod 204 and the connecting rod journal 203 must pass through the vertical line, if the vertical line is not passed, the crank body 201 cannot complete one circumferential movement, but the reciprocating rotation, which obviously cannot make the ducted turbofan body 51 complete circumferential rotation.
Therefore, a quadrant coordinate system is constructed with the vertical cross section of the crankshaft main body 201 as an origin. In an initial state where the reduction band plate 202 has no actual external force, the connection of the connecting rod 204 and the connecting rod journal 203 of the crankshaft main body 201 is located in the second quadrant, and in a limit where the reduction band plate 202 is forced to compress the spring assembly 205, the connection of the connecting rod 204 and the connecting rod journal 203 is located in the fourth quadrant.
That is, when the speed-reducing band plate 202 is forced (whether rolling of the automobile wheel or driving of the spring assembly 205), the force of the speed-reducing band plate 202 acting on the connecting rod 204 in the length direction of the connecting rod 204 is minimized, and the force of the speed-reducing band plate 202 acting on the connecting rod 204 is converted into a circumferential rotation force for driving the crank body 201 as much as possible, wherein the end of the crank body 201 is provided with the third transmission gear 208, and the crank body 201 is engaged with the second transmission gear 207 through the third transmission gear 208.
A guide seat 206 is arranged in a third quadrant of a quadrant coordinate system which is constructed by taking a longitudinal section of the crankshaft main body 201 and a rotation center of the crankshaft main body 201 as an origin, a guide cambered surface 207 is arranged on the guide seat 206, the longitudinal section of the guide cambered surface 207 is 1/4 arc or larger than the longitudinal section, and two ends of the guide cambered surface 207 extend to a second quadrant and a fourth quadrant respectively.
The connecting rod 204 contacts with the guide arc surface 207 when the connecting rod 204 and the connecting rod journal 203 enter the third quadrant, and since the time when the automobile contacts with the speed-reducing band plate 202 is short, the moment impact generated by the speed-reducing band plate 202 when the automobile is stressed is larger for the connecting rod 204, so that the moment impact of the connecting rod 204 to the connecting rod journal 203 is relieved, the crankshaft main body 201 rotates according to the stable circumferential direction, and the connecting rod 204 and the connecting rod journal 203 of the crankshaft main body 201 can be guided after entering the third quadrant, or the guide arc surface 207 is set at the connecting position of the second quadrant and the third quadrant to guide, thereby ensuring the stability of the rotation process of the crankshaft main body 201.
The invention aims at the change of the air flow in the tunnel (mainly aims at a unidirectional tunnel), and can clearly know that the air flow on the windward side of the automobile is compressed to the circumferential direction of the automobile after entering the tunnel and moves at the opposite speed to the automobile, and the air flow is mainly concentrated at the upper part of the automobile body to form upper air flow, so that the invention adopts a mode of sucking out the air in the tunnel to perform ventilation, and the first pipeline 2 is arranged at the top of the tunnel, and the air inlet of the first pipeline 2 is arranged perpendicular to the direction of the upper air flow, namely the upper air flow is actively captured. Of course, the car makes this upper air flow insignificant and the large car makes this upper air flow significant when it passes through the tunnel.
Therefore, the upper equidistant arrangement of the first pipeline 2 in the invention has the flat air inlets 6, an included angle exists between the flat air inlets 6 and the first pipeline 2, and the openings of the flat air inlets 6 face the running direction of the vehicle in the tunnel so as to intercept the upper air flow.
The third pipe 4 is connected to the body of the first pipe 2 between two adjacent flat air inlets 6.
The mechanical energy source of the present invention is that the deceleration strip 202 contacts and is rolled with the tire of the running automobile, so as to obtain the mechanical energy, wherein if the automobile directly rolls over the spring assembly 205, that is, the gravity of the automobile is mainly concentrated on the spring assembly 205, the spring assembly 205 is easily damaged, and the service life is reduced, so that the present invention combines the deceleration strip 202 with the real deceleration strip, thereby ensuring the function of the deceleration strip itself and reducing the overall damage degree of the driving module 1. The driving part in the invention is considered to be combined with a deceleration strip, a deceleration convex block 7 is arranged on the ground of a tunnel near the end part of the deceleration strip 202, and the height of the deceleration convex block 7 is the same as the ground clearance height of the end part of the deceleration strip 202 near the connecting rod 204.
In this case, the longitudinal section of the entire decelerator protrusion 7 and decelerator band plate 202 (in the initial state where the decelerator band plate 202 is not subjected to force) is trapezoidal, and the length of the trapezoidal inclined surface formed by the decelerator band plate 202 is smaller than the length of the inclined surface of the decelerator protrusion 7, so that the vehicle travels from the decelerator band plate 202 to the decelerator protrusion 7.
In the practical design process, in order to ensure the stability of the overall structure of the speed-reducing band plate 202, the end portion of the speed-reducing band plate 202, which is close to the connecting rod 204, goes deep into the inside of the speed-reducing bump 7, that is, the side edge of the speed-reducing bump 7, which is close to the speed-reducing band plate 202, is provided with a cavity for accommodating and rotating the side edge of the speed-reducing band plate 202. This requires that the motorbike wheel come into contact with the deceleration bump 7 before the motorbike wheel rolls the deceleration strip 202 such that the spring assembly 205 compresses to the spring limit of the spring assembly 205, thereby no longer stressing the deceleration strip 202.
Further, the spring assembly 205 of the present invention is only required to provide the initial position where the deceleration strip 202 can recover the set included angle, and the function thereof is to perform the conversion of the elastic potential energy, so the present invention may also be implemented by a hydraulic rod, a pneumatic rod, or the like, but since the motion of the deceleration strip 202 is instantaneous, the hydraulic rod or the pneumatic rod cannot better implement the rotation motion of the deceleration strip 202 in the foregoing, and thus the present invention provides a specific embodiment:
the spring assembly 205 comprises a plurality of bullet units, the bullet units comprise a guide rod 209, a pressure spring 210 is sleeved on the guide rod 209, one end of the guide rod 209 is in spherical hinge connection with the bottom surface of the deceleration strip plate 202, the other end of the guide rod 209 is deeply arranged in the ground or in a guide post groove 211 on a fixed seat structure connected with a guide seat, thus, in the rotating process of the deceleration strip plate 202, the guide rod 209 axially moves back and forth in the guide post groove 211, the bottom of the pressure spring is supported on the fixed seat structure surface, and the top of the pressure spring is connected with the deceleration strip plate 202.
According to the invention, through driving in the tunnel and by utilizing contact with wheels in the driving process, the ducted fan main body in the pipeline is driven in a purely mechanical mode, so that the transformation of electric energy and other energy situations is avoided, and the energy saving purpose of the tunnel ventilation system as a whole is achieved.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
