Abstract
The utility model relates to a balance and safety device for Yellow River engineering operation ships. The balance and safety device for the Yellow River engineering operation ships comprises two water storage tanks, the two ends of each water storage tank are respectively provided with a steering linkage disc, the water storage tanks are cylindrical, one horizontal sealing separation plate and one to three longitudinal sealing separation plates are arranged inside each water storage tank, the horizontal sealing separation plate divides the inner space of each water storage tank into two equal parts in an up-and-down mode, the longitudinal sealing separation plates divide the inner portion of each water storage tank into two to four sections in the length direction of the water storage tank, and a sea chest water inlet valve is arranged on the bottom of each section of the water storage tanks. The balance and safety device for the Yellow River engineering operation ships is simple in structure, low in manufacturing cost and capable of meeting balance and safety requirements of the Yellow River engineering operation ships, greatly improving the efficiency and safety of engineering operation and avoiding personal casualties and property losses.
Description
Technical field:
The utility model relates to flood control technical field, particularly a kind of balance safety device for the engineer operation ship on the Yellow River.
Background technology:
Eighties of last century seventies, the Yellow River worker brings into play the intelligence and wisdom research of oneself and has manufactured the simple and easy hydraulic suction dredge in the Yellow River, has from then on carried out and has reached the work of semicentennial river course sand pumping machine silt dyke strengthening, has guaranteed that the Yellow River is calm.Due to the simple and easy hydraulic suction dredge in operation from riverbank away from, need other ship to complete the work such as workman is on and off duty and material thing transports, installation or removal sediment delivery pipe, ship navigates by water operation in moving water, and overturning of vessel accident once repeatedly occurred, and causes casualties and the heavy losses of national wealth.Also once there is ship major casualties in the river gesture change prospecting and the dam bank root stone detection that carry out every year.For solving this technical barrier, according to yellow river regulation and water development real work needs, carried out thoroughgoing and painstaking ground res, applied hydraulics principle has been developed the balance safety device of Huanghe River Engineering operation ship.
Utility model content:
Technical solution adopted in the utility model is as follows:
A balance safety device for Huanghe River Engineering operation ship, comprises two reserve tanks, and the two ends of described reserve tank are respectively provided with one and turn to link dish; Described reserve tank is cylindrical shape, the inside of described reserve tank is provided with 1 horizontal airtight baffle and 1-3 longitudinal airtight baffle, described horizontal airtight baffle is separated into equal up and down two parts by described reserve tank inner space, described longitudinal airtight baffle is separated into 2-4 section along the length direction of described reserve tank by reserve tank inner space, and the bottom of every section of reserve tank is provided with a sea chest flood valve.
Balance safety device of the present utility model, simple in structure, cost is low, can meet balance and the security needs of Huanghe River Engineering operation ship, greatly improves efficiency and the safety of engineer operation, avoids personal casualty and property damage.
Accompanying drawing explanation:
Fig. 1: the engineer operation ship plan sketch that has adopted balance safety device of the present utility model.
The A-A sectional schematic diagram of Fig. 2: Fig. 1.
Fig. 3: the engineer operation ship schematic diagram in hydrostatic that has adopted balance safety device of the present utility model.
Fig. 4: the engineer operation ship schematic diagram in moving water that has adopted balance safety device of the present utility model.
In figure, 1 and 3 is reserve tank, and 2 is hull, and 4 for turning to link dish, and 5 is sea chest flood valve, and 6 is horizontal airtight baffle.
The specific embodiment:
As depicted in figs. 1 and 2, the balance safety device of Huanghe River Engineering operation ship of the present utility model, comprises two reserve tanks 1 and 3, and described reserve tank 1 and 3 two ends are respectively provided with one and turn to link dish 4; Described reserve tank 1 and 3 is cylindrical shape, described reserve tank 1 and 3 inside are provided with longitudinally airtight baffle (not shown) of 1 horizontal airtight baffle 6 and 1-3, described horizontal airtight baffle 6 is separated into equal up and down two parts by the inner space of described reserve tank 1 and 6, described longitudinal airtight baffle is separated into 2-4 section along the length direction of described reserve tank 1 and 3 by reserve tank inner space, and the bottom of every section of reserve tank is provided with a sea chest flood valve 5.Major part of the present utility model is metallic material.
Basic functional principle:
1, ship mode of operation not yet.When ship is can balance safety device not being installed before work, keep independently hull state to manage.When ship dead work by reserve tank 1 and 3 by turning to link dish 4 to be arranged on the both sides of hull 2.As depicted in figs. 1 and 2.
2, the ship state of starting working.When ship is started working, number depending on load carrying ability, opening sea chest flood valve 5 intakes in right amount, the little water inlet of load carrying ability is few, load carrying ability is intake many at most, maximum flooding quantity equals horizontal airtight baffle 6 lower volume moisture storage capacitys, and wait entering after water completes to close sea chest flood valve 5, locking turns to link dish 4.Now reserve tank 1 and 3 inside are basically identical with outside water level.As shown in Figure 3.
3, ship carries out mode of operation.When ship starts to carry out after work, operation ship is in current dynamically lower work rapidly, particularly run into the impact that water body eddy current and wind such as carry at the many factors, ship must on float downward and fall, swing after wigwag motion, preshoot, as shown in Figure 4, when hull is tilted to the left, hull center of gravity is moved to the left, when inclined angle alpha reaches unsafe degree, the buoyancy on horizontal airtight baffle 6 tops and the water weight of horizontal airtight baffle 6 bottoms, react on hull 2 centers of gravity and move right, now, balance safety device function plays one's part to the full.In like manner, when hull 2 is tilted to the right, controlled equally, can make ship carry out the work smoothly quite safe in the situation that.
Key problem in technology innovative point
(1) research and development of applied hydraulics principle are manufactured.
(2) simple in structure, cheap.
(3) easy to manufacture, mounting or dismounting convenience.
(4) flexible operation, effect are remarkable.
(5) there is independent buoyant apparatus function.
Use comparative effectiveness and promotional value
Application through standardized dikes for Lower Yellow River construction, has reached the object that ensures safety in production, lightens one's labor, increases work efficiency, saves Zhi Zengxiao, and safety misadventure never occurs every first stage construction.
Facts have proved that ship balance safety device of the present utility model has met the needs that Huanghe River Engineering is built, on the ship such as can be generalized to river course flow of water prospecting, the detection of engineering foundation, water conservancy Scene Tourist, shipping and fish for, apply.
