Description

Technical Field

[0001] This invention relates to the field of photovoltaic module transportation equipment technology, and in particular to an anti-slip and anti-tipping intelligent trailer for transporting photovoltaic modules in mountainous areas. Background Technology

[0002] With the increasing global demand for clean energy, the photovoltaic power generation industry has developed rapidly, and the scale of photovoltaic power plant construction has continued to expand. The site selection has also gradually shifted from flat land to areas with complex terrain such as mountains and hills. This has brought severe challenges to the transportation of photovoltaic modules.

[0003] Mountainous transportation environments are characterized by steep slopes, rugged and uneven roads, and loose soil. Traditional transport vehicles or simple trailers are prone to slipping, tilting, or even overturning under such conditions. Once an overturning occurs, it will not only cause expensive photovoltaic modules to break, resulting in huge economic losses, but may also cause casualties and seriously delay the progress of the project.

[0004] In existing technologies, although some transportation equipment has added simple anti-slip or anti-tipping structures, they are generally rigid supports that cannot provide cushioning when the vehicle tilts and resets. In other words, the reset process lacks speed control and is prone to causing secondary impacts on the vehicle body and cargo.

[0005] Therefore, in order to further improve the stability and reliability of photovoltaic modules during mountain transportation, we propose an anti-slip and anti-tipping intelligent trailer for photovoltaic module transportation in mountainous areas. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as rigid supports that cannot provide cushioning when the vehicle tilts, lack of control over the reset process, and susceptibility to secondary impacts on the vehicle body and cargo. This invention proposes an anti-skid and anti-tipping intelligent trailer for transporting photovoltaic modules in mountainous terrain.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Design a smart trailer for transporting photovoltaic modules in mountainous areas, which is anti-slip and anti-tipping, including a vehicle body and a frame installed on the top of the vehicle body; Two drive wheels are provided on each side of the vehicle body, and a track is provided between the two drive wheels; Anti-tilt mechanisms are provided on both sides of the frame, and damping mechanisms are provided on both sides of the lower part of the vehicle body. The anti-tilt mechanisms and damping mechanisms on opposite sides cooperate to realize the tilting and repositioning of the vehicle body.

[0008] Furthermore, the anti-tilt mechanism includes; Rotary swing arms connected to both sides of the frame; A crossbar is fixedly connected between the two swing arms, and an electric push rod is pinned to the top of the vehicle body. The shaft end of the electric push rod is rotatably connected to the crossbar.

[0009] Furthermore, an extension rod is movably inserted into the inside of the swing arm, and a waist groove is formed on the outer side of the swing arm. A drive rod is pinned to the side of the frame, and the end of the drive rod is rotatably connected to the extension rod via a shaft. The shaft slides in the waist groove.

[0010] Furthermore, a connecting lug is fixedly installed at the upper end of the swing arm, a rotating shaft is fixedly installed on the side of the frame, and a locking assembly is provided between the connecting lug and the rotating shaft.

[0011] Furthermore, the locking assembly includes an elastic ring, and a shaft hole adapted to the rotating shaft is provided on the end face of the connecting ear. The elastic ring is fixedly installed inside the shaft hole and sleeved on the outside of the rotating shaft. A ring tooth portion is also formed on the outer periphery of the rotating shaft, and a locking tooth that engages with the ring tooth portion is formed inside the shaft hole.

[0012] Furthermore, the damping mechanism includes; A sleeve is fixedly installed inside the vehicle body, and a push rod is inserted into the inner side of the sleeve. A piston is fixedly installed at the upper end of the push rod, and a spring is fixedly connected between the inside of the sleeve and the end of the push rod.

[0013] Furthermore, a one-way valve is provided on the outside of the sleeve, and an exhaust port is also provided on the outside of the sleeve.

[0014] Furthermore, multiple vent holes are spaced apart along the outer side of the sleeve, and a sealing sleeve is fitted on the outer side of the sleeve. The sealing sleeve is locked and fixed to the sleeve by fasteners, and the sealing sleeve is fitted on the outer side of the vent holes.

[0015] Furthermore, an electromagnetic push rod is fixedly installed on the inner side of the vehicle body, and a locking hole is opened on the outer side of the push rod. The shaft end of the electromagnetic push rod passes through the sleeve and is inserted into the locking hole.

[0016] Furthermore, the vehicle body is equipped with four motors, each of which is connected and adapted to the drive wheel.

[0017] The present invention proposes an intelligent anti-skid and anti-tipping trailer for transporting photovoltaic modules in mountainous areas. The advantages are as follows: the present invention achieves anti-tipping protection of the vehicle body through the coordinated work of the anti-tipping mechanism and the damping mechanism; when the vehicle body tilts, the anti-tipping mechanism will be activated immediately to support the vehicle body from the side and assist it in restoring; at the same time, the damping mechanism will start to play its role, controlling the restoring speed of the vehicle body in a damping manner to ensure that the vehicle body is slowly and smoothly righted, avoiding the impact caused by sudden landing.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-7 As an embodiment of the present invention, a smart trailer for transporting photovoltaic modules in mountainous terrain with anti-slip and anti-tipping features is disclosed. Specifically, the smart trailer includes a vehicle body 1 and a frame 2 installed on the vehicle body 1, the frame 2 being used to place photovoltaic modules. The vehicle body 1 described in this invention is also equipped with a controller. The controller housing is connected to the cloud via a wireless module, so that the user can operate it wirelessly. When transporting in mountainous areas, the unmanned transportation mode can be adopted to improve the convenience and safety of operation. Two drive wheels 10 are provided on both sides of the vehicle body 1, and a track 11 is provided between the two drive wheels 10. In this invention, the vehicle travels by means of the track 11, which can significantly increase the contact area with the ground, thereby playing a key anti-slip role and ensuring stable driving in wet and slippery road conditions such as mountainous areas. Anti-tilt mechanisms 3 are provided on both sides of the frame 2, and damping mechanisms 4 are provided on both sides of the lower part of the vehicle body 1. The anti-tilt mechanisms 3 and damping mechanisms 4 on opposite sides cooperate to realize the tilting and repositioning of the vehicle body 1.

[0022] In other words, the present invention achieves rollover protection for the vehicle body 1 through the coordinated operation of the anti-rollover mechanism 3 and the damping mechanism 4. When the vehicle body 1 tilts, the anti-rollover mechanism 3 will be activated immediately to support the vehicle body 1 from the side and assist it in resetting. At the same time, the damping mechanism 4 will start to play its role, controlling the resetting speed of the vehicle body 1 in a damping manner to ensure that the vehicle body 1 is slowly and smoothly straightened, avoiding the impact caused by sudden landing. This design can effectively protect the safety of the vehicle body 1 and the photovoltaic modules it carries.

[0023] In some embodiments, the anti-tilt mechanism 3 of the present invention includes; Rotary rods 31 are connected to both sides of the frame 2; A crossbar 32 is fixedly connected between the two swing arms 31, and an electric push rod 33 is pinned to the top of the vehicle body 1. The shaft end of the electric push rod 33 is rotatably connected to the crossbar 32.

[0024] Based on the above embodiments, in this embodiment of the invention, the swing rod 31 is internally movably connected to an extension rod 34, and a waist groove 35 is provided on the outer side of the swing rod 31. The side of the frame 2 is pinned to a drive rod 36, and the end of the drive rod 36 is rotatably connected to the extension rod 34 through a shaft. The shaft slides in the waist groove 35.

[0025] Specifically, during actual operation, the tilt sensor can be used to detect the attitude of the vehicle body 1. When the vehicle body 1 tilts, the electric push rod 33 is activated, and the shaft end of the electric push rod 33 extends to drive the swing rods 31 on both sides to rotate through the crossbar 32. When the two swing arms 31 are rotating, the end of the drive rod 36 will pull the extension rod 34 through the shaft. Therefore, the extension rod 34 will move outward until the end of the extension rod 34 touches the ground. At this time, the support for the side roll of the vehicle body 1 can be completed. After that, under the action of the weight of the vehicle body 1, the entire vehicle body 1 begins to rotate and reset. Of course, in this invention, a secondary electric actuator can also be installed inside the extension rod 34. The secondary electric actuator is used to contact the ground to achieve automatic reset of the vehicle body 1. That is, when the vehicle body 1 is tilted and the shaft end of the secondary electric actuator contacts the ground, the shaft end of the secondary electric actuator can extend to control the reset of the entire vehicle body 1.

[0026] Based on the above embodiments, in this embodiment of the invention, a connecting lug 38 is fixedly installed at the upper end of the swing arm 31, and a rotating shaft 21 is fixedly installed on the side of the frame 2. A locking assembly 37 is provided between the connecting lug 38 and the rotating shaft 21. The locking assembly 37 is used to circumferentially lock the connecting lug 38 and the rotating shaft 21. This can prevent the swing arm 31 from being subjected to excessive force when the vehicle is tilted, which would be transmitted to the electric push rod 33 and cause damage to the electric push rod 33.

[0027] Preferably, in this embodiment, the locking component 37 includes an elastic ring 371, and the end face of the connecting ear 38 is provided with a shaft hole adapted to the rotating shaft 21. The elastic ring 371 is fixedly installed inside the shaft hole and sleeved on the outside of the rotating shaft 21. A ring tooth portion 372 is also formed on the outer periphery of the rotating shaft 21, and a locking tooth 373 that engages with the ring tooth portion 372 is formed inside the shaft hole.

[0028] In other words, the locking component 37 in this embodiment is an adaptive locking mechanism based on the elastic ring 371 and the toothed structure, and its working principle is as follows: In the initial state, supported by the elastic ring 371, the shaft hole of the connecting ear 38 is concentric with the rotating shaft 21, and the rocker arm 31 can rotate freely.

[0029] When the vehicle body 1 tilts to the side and the swing arm 31 unfolds and supports the ground, if the impact force is too large, the force will be transmitted through the swing arm 31, causing eccentric compression between the connecting lug 38 and the rotating shaft 21. This eccentricity will compress the elastic ring 371, causing the locking teeth 373 in the shaft hole to lock together with the ring teeth 372 on the rotating shaft 21.

[0030] The meshing of the toothed structure creates a powerful circumferential locking force, instantly preventing the rocker arm 31 from continuing to rotate, thereby absorbing the impact force and effectively protecting the electric actuator 33 that drives the rocker arm from damage.

[0031] Preferably, the elastic ring 371 described in this invention can be a rubber ring.

[0032] In some embodiments, the damping mechanism 4 of the present invention includes; A sleeve 41 is fixedly installed inside the vehicle body 1. A push rod 42 is inserted into the inner side of the sleeve 41. A piston 43 is fixedly installed at the upper end of the push rod 42. A spring 44 is fixedly connected between the inside of the sleeve 41 and the end of the push rod 42.

[0033] Of course, the piston 43 described in this invention is sealed between the push rod 42 and the sleeve 41. In addition, in order to form an effective damping force, a one-way valve 45 is provided on the outside of the sleeve 41 in this invention, and an exhaust hole 47 is also provided on the outside of the sleeve 41.

[0034] Specifically, the one-way valve 45 described in this invention is used to supply air to the inside of the sleeve 41, while not conducting in the other direction. In addition, the exhaust port 47 described in this invention adopts a small hole design, which utilizes the principle of slow gas discharge through the small hole to create an effective air resistance effect.

[0035] Based on the above embodiments, in this invention, multiple exhaust holes 47 are provided at intervals along the outer side of the sleeve 41, and a sealing sleeve 48 is sleeved on the outer side of the sleeve 41. The sealing sleeve 48 is locked and fixed to the sleeve 41 by fasteners, and the sealing sleeve 48 is sleeved on the outer side of the exhaust hole 47.

[0036] In other words, when the sealing sleeve 48 slides along the outer wall of the sleeve 41, its relative position with the exhaust hole 47 changes, thereby adjusting the number of exhaust holes 47 that are blocked. When the sealing sleeve 48 blocks a large number of exhaust holes 47, the exhaust capacity of the damping mechanism 4 is poor, the internal gas is discharged slowly, and therefore the damping force generated is large, which slows down the rotation and reset speed of the vehicle body 1. Conversely, when the number of vent holes 47 exposed by the sealing sleeve 48 is large, the venting capacity of the damping mechanism 4 is enhanced, and the internal gas can be discharged quickly. Therefore, the damping force generated is small, which speeds up the rotation and reset speed of the vehicle body 1. Through this structure, the rotation and reset speed of the vehicle body 1 can be controlled to ensure that it is smooth and impact-free during the reset process, thereby effectively protecting the safety of the vehicle body 1 and the photovoltaic modules it carries.

[0037] Based on the above embodiments, in this embodiment of the invention, an electromagnetic push rod 49 is also fixedly installed on the inner side of the vehicle body 1, and a locking hole 46 is opened on the outer side of the top rod 42. The shaft end of the electromagnetic push rod 49 passes through the sleeve 41 and is inserted into the locking hole 46.

[0038] In other words, when vehicle body 1 rolls over, the control system (not shown in the figure) issues a command. On one hand, electric actuator 33 drives swing arm 31 to rotate and unfold to provide initial support. At the same time, the shaft end of electromagnetic actuator 49 retracts, releasing the locking restriction on push rod 42. Driven by the elastic force of spring 44, push rod 42 quickly extends outward until its end touches the ground, forming emergency support.

[0039] During the process of the vehicle body 1 starting to rotate and reset, the retraction of the push rod 42 will trigger the damping mechanism 4 to work. Specifically, the retraction of the push rod 42 will push the piston 43 to move inside the sleeve 41, thereby compressing the air. The compressed air can only be discharged through the exhaust port 47, thus forming an air damping effect. This damping force effectively suppresses the reset speed of the vehicle body 1, allowing it to slowly and smoothly return to the correct position, avoiding secondary impacts caused by rapid reset, thereby providing effective protection for the vehicle body 1 and the photovoltaic modules it carries.

[0040] It should be noted that, in this embodiment of the invention, four motors are installed inside the vehicle body 1, and each motor is connected and adapted to the drive wheel 10.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
