Description

Technical Field

[0001] This invention relates to the field of vehicle rescue device technology, specifically a rescue device for vehicles getting out of trouble in the desert. Background Technology

[0002] Cars often break down in the desert when their wheels get stuck in loose sand. This can have serious consequences. For example, water is scarce in the desert, and without sufficient water and food, drivers and passengers risk dehydration and hunger. Additionally, the high temperatures and low humidity in the desert cause rapid dehydration, putting drivers and passengers at risk of heatstroke and dehydration. Furthermore, cars that break down in the desert are often far from cities and roads, making it difficult to seek help. The loose sand and lack of trees also make it difficult to find objects to anchor tow ropes. Therefore, there is an urgent need for a rescue device that can anchor tow ropes to help cars get out of trouble in the desert. Summary of the Invention

[0003] The purpose of this invention is to provide a rescue device for vehicles getting out of trouble in the desert, which can establish anchor points for trailers in soft desert and help vehicles get out of trouble.

[0004] To achieve the above objectives, the present invention provides a rescue device for vehicles getting out of trouble in the desert, comprising a central cylinder, an anchor plate, a ventilation connection structure, and a nozzle, wherein one end of the central cylinder is connected to the nozzle and the other end is connected to the ventilation connection structure; the anchor plate is connected to the central cylinder via a rotating shaft and can be extended outward around the rotating shaft; a fixing ring is provided on the side of the central cylinder away from the rotating shaft for installing a tow rope.

[0005] Furthermore, the ventilation connection structure includes a ventilation hose and a hollow plug, with one end of the ventilation hose connected to the central cylinder and the other end connected to the hollow plug.

[0006] Furthermore, multiple anchor plates are provided and are evenly distributed along the circumference of the central cylinder.

[0007] Furthermore, a trigger plate is vertically disposed at the end of the anchor plate away from the rotating shaft, and the trigger plate is provided with a plurality of mesh holes.

[0022] To achieve the above objectives and effects, the technical means and structure adopted by the present invention will be described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of the present invention.

[0023] like Figure 1-4As shown, the present invention provides a rescue device for vehicles getting out of trouble in the desert, including a central cylinder 1, an anchoring plate 2, a ventilation connection structure, and a nozzle 4. The central cylinder 1 is hollow inside, allowing airflow to pass through it. One end of the central cylinder 1 is connected to the nozzle 4, and the other end is connected to the ventilation connection structure. The anchoring plate 2 is connected to the central cylinder 1 via a rotating shaft 3 and can be extended outward around the rotating shaft 3. A fixing ring 5 is provided on the side of the central cylinder 1 away from the rotating shaft 3 for installing a tow rope 8.

[0024] The ventilation connection structure includes a ventilation hose 6 and a hollow plug 7. One end of the ventilation hose 6 is connected to the central cylinder 1, and the other end is connected to the hollow plug 7. In use, the hollow plug 7 is inserted into the car exhaust pipe to block it, so that the exhaust gas generated by the car can only pass through the hollow plug 7, the ventilation hose 6, and the central cylinder 1 before being ejected from the nozzle 4 at the front end.

[0025] In this embodiment, multiple anchor plates 2 are provided and evenly distributed along the circumference of the central cylinder 1. A trigger plate is vertically provided at the end of the anchor plate 2 away from the rotating shaft 3. The trigger plate is provided with several mesh holes, the mesh size of which is between 2 and 8 meshes. This allows fluidized sand to pass through while blocking non-fluidized sand, so that the rescue device can be easily pulled out by the tow rope 8 for reuse.

[0026] In this embodiment, the middle part of the outer wall of the central cylinder 1 is hinged to the anchor plate 2 via a telescopic mechanism. The telescopic mechanism includes a pull rod 10 and a spring 12. The inner wall of the anchor plate 2 away from the rotating shaft 3 is provided with a sliding groove 11. One end of the pull rod 10 is hinged to the central cylinder 1 via a hinge 9, and the other end is slidably connected in the sliding groove 11. One end of the spring 12 is hinged to the central cylinder 1 via a hinge 9, and the other end is hinged to the pull rod 10 via a hinge 9. The sliding groove 11 is fixed inside the end of the anchor plate 2 and is connected to the pull rod 10 via the hinge 9. Its contraction and expansion are controlled by the pull rod 10. Under the tension of the spring 12, the anchor plate 2 is driven by the pull rod 10 to contract onto the wall of the central cylinder 1.

[0027] In this embodiment, the nozzle 4 has several air outlets at its end. The nozzle 4 allows a large flow of air to pass through, and preferably, it has six air outlets at its end.

[0028] Furthermore, the hollow plug 7 is made of a flexible material and needs to have large deformation characteristics, so it can be made of rubber.

[0029] Furthermore, in order to ensure smooth internal airflow, the ventilation hose 6 needs to be pressure-resistant, unbreakable, and non-deformable, and can be made of threaded hose.

[0030] This invention utilizes the fluidization properties of sand to establish a stable anchor point in loose desert soil, thereby helping vehicles to get out of trouble. The device has a wide range of applications. This invention uses the vehicle's own exhaust gases to fluidize the sand, without consuming additional energy, making it energy-saving and environmentally friendly. This invention not only has a compact structure and low production cost, but also features convenient operation and low labor costs.

[0031] The working principle of this invention is as follows:

[0032] When a car gets stuck in the desert, this invention inserts a hollow plug 7 into the car's exhaust pipe to block it, so that the exhaust gas produced by the car can only pass through the hollow plug 7, the ventilation hose 6, and the central cylinder 1 before being ejected from the nozzle 4 at the front end. The nozzle 4 of this rescue device is then inserted vertically downwards into the desert, and a large amount of airflow is blown into the gaps between the sand grains, increasing the spacing between the grains and causing a sharp decrease in the friction between them. This transforms the originally solid sand into a near-fluid state, i.e., the sand fluidization phenomenon. Under its own weight, the device can easily sink in the fluidized sand.

[0033] Once a certain depth is reached, the hollow plug 7 is pulled out. When the nozzle 4 stops spraying air, the fluidization of the sand disappears, and it becomes solid again. The tow rope 8 connected to the fixing ring 5 is tied to the car's drive wheel, allowing the drive wheel to act as a winch. As it rotates, the tow rope 8 is tightened, causing the device to move backward. The fixed sand particles prevent the trigger plate from passing through, which in turn causes the anchor plate 2 to open outward, further preventing the rescue device from moving and forming a solid anchor point. This provides sufficient tension for the tow rope 8, pulling the car out and freeing it from the predicament.

[0034] The hollow plug 7 is inserted into the car's exhaust pipe again to block it, so that the exhaust gas produced by the car can only pass through the hollow plug 7, the vent hose 6, and the central cylinder 1 before being sprayed out from the front nozzle 4. The sand is fluidized again, and under the tension of the spring 12, the anchor plate 2 retracts to the wall of the central cylinder 1. At the same time, the fluidized sand can freely pass through the perforated trigger plate, allowing the rescue device to be easily pulled out by the tow rope 8 for reuse.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
