Description
Technical Field
The invention relates to a wave board device, a control method and an amphibious vehicle, and belongs to the field of vehicle engineering.
Background
The amphibious vehicle combines the dual performances of a vehicle and a ship, has good amphibious passage performance, and is an important transportation tool. To improve the sailing performance of the vehicle in water, a breakwater device is used.
The traditional breakwater device adopts an upward tipping unfolding mode, and uses a manual or manual hydraulic pump to realize unfolding and retracting. The upper tipping unfolding mode is adopted, so that the wave-preventing plate is retracted and then covered above the front part of the vehicle body, and the maintenance of the power cabin at the front part of the vehicle body is inconvenient; (2) The manual operation or the manual pulling operation of the driver can be used for expanding the pumping pressure rod, and the operation of retraction can be used for ensuring that the working intensity of the driver is high; (3) The expansion and retraction time of the breakwater is long, and one action is about 2 minutes.
Prior art, such as chinese patent, application number: CN2013202155440, bulletin number: CN203432465U, discloses a wave plate operating mechanism for amphibious wheel type armored vehicle. What described in this patent is a structure that utilizes the capstan winch to drive the unrestrained board body of breakwater and slide from top to bottom, and this kind of structure has decided that its fixed knot constructs and is far away from the breakwater bottom, and cantilever part is too long when leading to the breakwater operating condition, and stability is not strong, can not bear too big effort. When the amphibious vehicle sails on the sea, the stormy waves in the sea are detected, and potential safety hazards exist in the vehicle. In addition, the use state of the wave plate is only one angle, and the angle cannot be adjusted according to factors such as sea waves and the like so as to obtain minimum resistance.
Application number: CN202110410775, publication No.: CN113022243 a; application number: CN202110410778x, publication No.: CN113147291 a discloses an amphibious vehicle. The folding breakwater referred to in this patent can adjust the deployment angle by two sets of electric pushrods, thereby reducing the resistance of the vehicle when it is advancing underwater. However, when the vehicle is driven on land, the upper edge of the breakwater is still higher than the outer surface of the top deck of the vehicle body after the two groups of electric push rods are fully retracted. Therefore, the use of the wave plate structure has a certain limitation, if the vehicle is a manned vehicle, the retracted wave plate can block the vision of the driver, and the running on the land can be interfered, so that the running safety can be influenced.
Application number: CN2020115208949, publication No.: CN112549882 a discloses an electrically driven breakwater. The patent relates to an upturned breakwater device which is retracted above the head deck when the breakwater is not in use. However, most of the engines of special vehicles are positioned at the front part of the vehicle, and the daily maintenance of the engines must be carried out by unfolding the breakwater before opening the engine hatch for maintenance.
Application number: CN2010100501098, bulletin number: CN106134341B discloses a wave plate mechanism for wheeled armored vehicles. The breakwater control mechanism is simple and practical in structure, is also of an upturned structure, and can be used for daily maintenance of the engine only by opening the breakwater. In addition, the unfolding and the retraction of the mechanism are operated by manual operation, so that the workload of operators is increased; being unable to extend and retract while the vehicle is in motion, if a war occurs, the parking maneuver tends to increase the likelihood of injury.
In addition, the prior art, such as chinese patent, has application number: CN201320023049x (CN 201310016201.6), bulletin number: CN203063604U (publication No. CN103112327 a), discloses a front breakwater for amphibious vehicle; publication No.: JP-2-185811A, US2009/0124142A1, CN213414977U, journal, university of Beijing university journal, volume 23, first edition, authors: liu Shuyan, etc., discloses an amphibious vehicle water performance test study of improved design, however, the above-mentioned prior art all involves the breakwater and its structure, but the above-mentioned prior art can not realize that when the inside daily maintenance of power cabin need not to open the breakwater, expand, withdraw the drawback such as action separation control, increase driver's working strength.

The specific operation is completed in the vehicle by a driver:
1) Unfolding the wave plate: when the breakwater assembly 1 is in the retracted position (shown in fig. 2), the breakwater control switch on the control panel of the driver is shifted to the unfolding position, the electric push rod control box receives an unfolding instruction, and the electric push rod 5 stretches out to drive the breakwater assembly 1 to be overturned and unfolded; when the breakwater assembly 1 is overturned to the unfolding position, the automatic stop is realized, the electric push rod control box sends an unfolding in-place signal to the display terminal of the driver, and after the driver sees the unfolding in-place signal of the breakwater, the breakwater control switch on the driver control panel is shifted to the middle position, so that the unfolding of the breakwater is completed. Meanwhile, the electric push rod 5 is locked, so that the unfolding state of the breakwater is unchanged when the vehicle sails on water.
2) Retracting the breakwater: when the breakwater assembly 1 is in the unfolding position (shown in figure 1), a breakwater control switch on a driver control panel is moved to a retraction position, an electric push rod control box receives a retraction command, and an electric push rod 5 is retracted to drive the breakwater assembly 1 to be overturned and retracted; when the breakwater assembly 1 is overturned to the retraction position, the automatic stop is realized, the electric push rod control box sends a retraction signal to the display terminal of the driver, and after the driver sees the breakwater retraction signal, the breakwater control switch on the driver control panel is shifted to the middle position, so that the breakwater retraction is completed. Meanwhile, the electric push rod 5 is locked, so that the wave plate is kept in a retracted state when the vehicle runs on land.
