Detailed ways

The utility model is further described below with specific examples, but the utility model is not limited by the following examples.

Example 1.

As shown in Figure 1, a kind of dredging ship that realizes automatic operation, it comprises sand pumping equipment, and described sand pumping equipment comprises sand suction device 1 and water pump group 2, and described sand suction device 1 comprises clear water pipe 3, vacuum chamber 4 , the upper sand nozzle 5 and the upper sand pipe group 6, the vacuum chamber 4 is provided with a nozzle 7, the upper sand nozzle 5 communicates with the vacuum chamber 4, and the vacuum chamber 4 communicates with the upper sand pipe group 6 The water pump group 2 is two groups or more than two groups; each group of the water pump group 2 includes a water pump 22 and two power generation equipment 21, and the water pump 22 is connected with the power generation equipment 21; two groups or more than two groups The water pumps 22 of the water pump group 2 are connected in series; a PLC control system 8 is also included, and the PLC control system 8 is electrically connected with the power generation equipment 21.

The PLC control system 8 of this embodiment realizes automatic and intelligent operation, and synchronously controls the two power generating equipment 21, which saves human resources and reduces control errors; The power generation equipment 21 can reduce loss compared with using a power generation equipment with a larger power, and the selection range of the power generation equipment 21 is wider.

Specifically, the water pump group 2 of this embodiment is divided into two groups. When two water pumps 22 are connected in series, Q _series =Q ₁ =Q ₂ , H _series =H ₁ +H ₂ , and H=P/ρ (ρ is water Density, 1000kg/m ³ ), it can be seen that P _string = P ₁ +P ₂ . When two water pumps 22 work in series, the pressure of the vacuum chamber 4 increases, and the pressure generated inside and outside the upper shackle 5 increases, and the suction of the upper shackle 5 increases, and the sand mining amount of the upper shackle 5 is large.

Adopt the mode of series connection water pump 22 to increase pressure, increase the sand excavation output of Shangshazui 5, can choose the power generation equipment 21 of low power and water pump 22, energy saving and environmental protection, take up a small volume, can reduce the volume of hull and displacement tonnage.

Specifically, the upper sand tube group 6 includes a mixing tube 61, a diffuser tube 62 and an upper sand tube 63, the mixing tube 61 is connected to the vacuum chamber 4 and the diffuser tube 62 respectively, and the diffuser tube 62 is connected to the diffuser tube 62. The upper sand pipe 63 is connected.

When in use, the water pump unit 2 will continuously pump high-speed water flow into the clean water pipe 3. When the high-speed water flow is ejected through the nozzle 7, the vacuum chamber 4 will be in a state of close to vacuum, making the inside and outside of the upper sand nozzle 5. Larger pressure difference, thereby forming a strong suction, sucking the sediment and water at the bottom of the water into the upper sand nozzle 5, and then passing through the vacuum chamber 4, the mixing pipe 61, the diffusion pipe 62, and then entering the upper sand pipe 63, The upper sand pipe 63 is connected with the sand washing tank, and finally, the mixed silt flows into the sand washing tank with the high-speed current to achieve the purpose of sand pumping.

The power generation equipment 21 described in this embodiment is a diesel generator, and the diesel generator includes a diesel engine, a generator and an electric motor, the diesel engine is connected to the generator, the generator is connected to the motor, and the motor is connected to the motor. The water pump 22 is connected.

The diesel engine can choose a diesel engine with a power of 110KW or above, which reduces investment costs and operating costs, and can also reduce the volume and displacement tonnage of the hull.

The power generation equipment 21 in this embodiment may also be a heavy oil engine or a natural gas engine.

Heavy oil engines are mostly medium and low-speed generators, which mainly have the advantages of low operating cost, long-term continuous operation and reliable operation, long service life and low noise.

The natural gas engine has the advantages of wide output power range, high reliability in start-up and operation, good power generation quality, simple maintenance, and low-frequency noise. Since natural gas is an environmentally friendly and clean energy, it can reduce environmental pollution. The operating cost of natural gas engines is lower than that of heavy oil The engine is lower.

The power generation equipment 21 is not limited to the above three types, and different types can be selected according to production requirements.

Example 2.

As shown in FIG. 2 , the difference between this embodiment and Embodiment 1 is that: the water pump sets 2 in this embodiment are three sets, and the three water pumps 22 of the three sets of water pump sets 2 are connected in series.

When three water pumps 22 are connected in series, Q _string =Q ₁ =Q ₂ =Q ₃ , H _string =H ₁ +H ₂ +H ₃ , and H=P/ρ (ρ is the density of water, 1000kg/m ³ ), It can be seen that P _string =P ₁ +P ₂ +P ₃ . When three water pumps 22 work in series, the pressure of vacuum chamber 4 increases, and the pressure that goes up husky 5 inside and outside produces increases, and the suction of husky 5 increases, and the sand mining amount of husky 5 is big.

Adopt the mode of series connection water pump 22 to increase pressure, increase the sand excavation output of Shangshazui 5, can choose the power generation equipment 21 of low power and water pump 22, energy saving and environmental protection, take up a small volume, can reduce the volume of hull and displacement tonnage.

As shown in Fig. 3, Fig. 4, and Fig. 5, the water pump group 2 of the present embodiment can also be five groups or six groups or eight groups, and the quantity of the water pump group 2 is more, and the sand extraction rate of the upper sand nozzle 5 is just bigger .

The number of water pump sets 2 is not limited to the number of this embodiment, and different combinations can be selected according to actual conditions.

Features that are not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
