Description

Technical Field

[0001] The invention relates to fire rescue equipment, in particular to an underwater self-righting device for an all-terrain amphibious vehicle. Background Art

[0002] Small and medium-sized amphibious rescue vehicles can provide a safe mode of transportation and a reliable platform. The products can achieve all-weather continuous operation in a variety of working environments such as mountainous environments, wetland environments, swamp environments, water environments, jungle environments, etc. It has the ability to pass through extremely harsh ground and has excellent water passability. It can patrol and survey at the disaster site, transport injured people, and effectively implement rescue. Without being restricted by bridges or ships, it can directly transition from land to water, which is convenient for water rescue. For example, in the case of urban waterlogging and floods, amphibious vehicles can quickly enter the waterlogged area, evacuate trapped people, and drag out trapped vehicles. Moreover, in water rescue, amphibious vehicles can also be used as water rescue command vehicles for on-site command and coordination.

[0003] Although small and medium-sized amphibious rescue vehicles have the characteristics of strong terrain adaptability and high rescue flexibility, due to their own structural limitations, the following problems are still found in actual use: First, due to the structural limitations of the chassis structure and the land walking device, the amphibious vehicle will generate greater resistance when moving in the water, thereby affecting its speed in the water; Second, due to the relatively small overall volume and the limitations of the overall structural frame, even if certain sealing means are used to ensure the necessary displacement, there are often cases of poor buoyancy in actual rescue situations, making it impossible to travel stably in strong currents or large waves, and its wave resistance is poor, and it is easily affected by waves and loses stability.

[0004] Therefore, how to improve the stability of small and medium-sized amphibious rescue vehicles in water is a technical problem that needs to be urgently solved in this field. The present invention aims to propose a solution that can better ensure the stability of the vehicle body when it stays or moves in water without excessively increasing the total burden of the vehicle body.

[0024] The present invention is further described below in conjunction with the accompanying drawings and examples. The embodiments of the present invention include but are not limited to the following examples.

[0025] Example

[0026] like Figures 1 to 5 As shown, the all-terrain amphibious vehicle in-water self-righting device comprises an inflatable pylon 1 respectively arranged on both sides of the body of the amphibious vehicle and matching the length of the side of the body, an air bag 2 arranged inside the inflatable pylon and equipped with an air inlet 3 and an exhaust port 4, a pressure sensor arranged on the air bag, an inflation and deflation mechanism 5 arranged on the inflatable pylon and connected to the air bag for respectively inflating and deflation of the air bag, a righting controller 6 electrically connected to the inflation and deflation mechanism and the pressure sensor, and a connecting frame 7 arranged on the inflatable pylon near one side of the body, a connector matching the connecting frame is provided on the body of the amphibious vehicle, a trigger switch electrically connected to the righting controller is provided on the connecting frame, and when the connecting frame is docked with the connector, the trigger switch is turned on, so that the righting controller can control the inflation and deflation mechanism to operate to inflate the air bag, and the inflation amount is determined according to the signal fed back by the pressure sensor. Usually, the pressure sensor is arranged at the air inlet or / and exhaust port of the air bag, and the accuracy of air bag pressure monitoring can also be improved by comprehensive configuration of multiple pressure sensors. The trigger switch can be configured as a spring switch or a micro switch, and the connection frame and the connection head are matched and aligned by docking. After the connection frame and the connection head are docked, a locking mechanism is used to lock them.

[0027] Specifically, the expandable bracket includes a back frame 10 made of a hard material and arranged on the side close to the vehicle body, a slot structure 11 for accommodating an airbag and arranged on the outside of the back frame, and an outer guard 12 made of a flexible and tough material connected to the back frame at the edge of the slot structure. The air inlet and exhaust port of the airbag are usually connected to the back frame through a joint. The outer guard and the back frame together form an expandable chamber based on the slot structure, and the expandable chamber expands or contracts with the inflation or deflation of the airbag. The structure of the expandable chamber can effectively protect the airbag from being damaged by external scratches. The expandable chamber can be configured as a cylinder in the expanded state to facilitate the extension and contraction of the airbag. When the airbag is in the contracted state, the outer guard can also collapse accordingly, thereby reducing the storage volume of the device as a whole.

[0028] Specifically, the inflation and deflation mechanism includes a micro air pump 13, a first two-position three-way solenoid valve 14 and a second two-position three-way solenoid valve 15 electrically connected to the righting controller, wherein the first two-position three-way solenoid valve is connected to the pipeline between the micro air pump outlet and the air inlet of the airbag, and its third port is connected to the exhaust pipeline 16, and the second two-position three-way solenoid valve is connected to the pipeline between the micro air pump inlet and the air bag exhaust port, and its third port is connected to the intake pipeline 17; when the inflation and deflation mechanism inflates the airbag, the first two-position three-way solenoid valve connects the micro air pump outlet with the air inlet of the airbag, and the second two-position three-way solenoid valve connects the micro air pump inlet with the intake pipeline; when the inflation and deflation mechanism deflates the airbag, the first two-position three-way solenoid valve connects the micro air pump outlet with the exhaust pipeline, and the second two-position three-way solenoid valve connects the micro air pump inlet with the air bag exhaust port. The inflation and deflation mechanism and the righting controller can be configured in an external interior as a whole and installed in the middle of the back frame, which can improve the inflation and deflation efficiency to a certain extent.

[0029] Specifically, the righting controller includes a processing unit, an air pump control unit, a first solenoid valve unit, a second solenoid valve unit, an adjustment unit and a display unit electrically connected to the processing unit respectively, the trigger switch and the pressure sensor are electrically connected to the processing unit, wherein the air pump control unit is electrically connected to the micro air pump, the first solenoid valve unit is electrically connected to the first two-position three-way solenoid valve, and the second solenoid valve unit is electrically connected to the second two-position three-way solenoid valve. The display unit is used to display airbag pressure information, air pump operation information and maximum pressure limit information, and the adjustment unit is used to manually input the current inflation and deflation state and load information. The current inflation and deflation state indicates whether it is currently in an inflation state or a deflation state. The load information can be configured with fixed vehicle preparation information on the one hand, and can be configured with current load information on the other hand. The processing unit automatically adjusts the inflation and deflation mechanism operation parameters and maximum pressure limit information according to the current load information and airbag pressure information and in combination with the trigger switch state, and then transmits the inflation and deflation mechanism operation parameters to the air pump control unit, the first solenoid valve unit and the second solenoid valve unit respectively to realize the control of the inflation and deflation mechanism.

[0030] In addition, the righting controller is also connected to the amphibious vehicle console through a wireless module, so that the righting controller can be controlled by the control module built into the amphibious vehicle console, so that the righting controller can be operated directly inside the vehicle body instead of on the righting controller, thereby improving the convenience of operation. The wireless module can be configured using the Zigbee protocol to ensure that the devices on both sides can be synchronized.

[0031] Specifically, the all-terrain amphibious vehicle underwater self-righting device is also configured with a power supply module, and the power supply module is powered by a battery or draws power from the body of the amphibious vehicle.

[0032] The present invention is mainly used in water operations during practical application. When traveling on land, it can be removed and placed, or installed but not inflated, to ensure that the width of both sides of the vehicle body does not affect normal travel on land. The airbag can be installed and inflated before launching, or pre-inflated before reaching the launching position, or inflated immediately after launching. The operation can be directly operated through the righting controller, or through the control module of the vehicle body console. When the feedback data of the pressure sensor meets the standard, its function can be exerted. After inflation, the airbag and the inflatable bracket expand toward the two outer sides of the vehicle body, and provide additional buoyancy support, so that the amphibious vehicle is more wave-resistant in the water and travels more smoothly in the water.

[0033] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any changes made by adopting the design principles of the present invention and performing non-creative work on this basis should fall within the protection scope of the present invention.
