Description
Technical Field
The invention relates to the technical field of pipeline transportation, in particular to a pipeline transportation system with power optimization and a transportation method.
Background
The land transportation system mainly comprises road transportation and railway transportation. Road transportation needs to consume a large amount of fossil energy, transportation cost is high, and consumption of fossil energy can discharge a large amount of greenhouse effect gases, waste materials and the like, causing environmental pollution. Compared with road transportation, railway transportation has low transportation cost, but the investment for building railways is huge, and the requirements on the terrain and the geology are high in the railway building process. For example, when a valley is encountered, a railway bridge needs to be erected; when encountering mountain, tunneling is required. Meanwhile, the railway construction has high requirements on the roadbed, and a large amount of basic treatment engineering is needed when the railway construction meets soft geological strata. Due to the above factors in railway construction, the investment for constructing railways is usually huge.
In terms of transportation cost, the water ship transportation, the railway train transportation, the road automobile transportation and the air airplane transportation are carried out from low to high in sequence. For the transportation system, the automobile transportation needs to depend on or build a road, the train operation needs to depend on or build a railway, the water transportation needs to have a channel and a cargo ship, and the air transportation needs to have an airplane. In the above various transportation modes, a large amount of capital needs to be invested in automobile transportation and train transportation to build infrastructures such as roads and railways, and automobiles and train carriers need to be invested on the basis of the infrastructures; the ship transportation is only suitable for seas or big rivers with channels; air transportation requires large investments in purchasing airplanes, and is limited or influenced by geographic location, weather, distance, etc.
Particularly, in the case of point-to-point transportation, the investment for construction is huge whether road transportation or railway transportation is constructed. In addition, point-to-point transportation makes the line have single function, so that the economic benefit is limited. For example, coal transportation from a coal mine site to a power plant and from a coal mine site to a chemical plant is huge, and the construction cost of transportation lines is difficult to recover. And the later stage operation of the transportation of the highway and the railway is also influenced by weather such as rain, snow, fog and the like, so that the environmental protection problem exists.
The inventor is actively making research and innovation based on professional knowledge and combining with rich engineering experience accumulated in the pipeline transportation field, and has already obtained a series of patents in the pipeline transportation field. CN110171712B discloses a transportation pipeline and a transportation method using the transportation pipeline. The main technical content is as follows: the capsule filled with solid goods is placed in a closed water-filled pressure pipeline, the influence of the terrain height difference is eliminated by using the buoyancy of water, and only a small fixed water head is needed to meet the water head friction loss between the water body flow in the pipeline and the pipe wall. And the fixed water head is provided by pressurizing with the water pump, and only little electric energy is consumed.
Technical problem
The water in the transportation pipeline flows integrally in the pipeline under the action of the pressurization system, so that the capsule is driven to carry goods to realize transportation, and along with the increase of the transportation pipeline, the energy consumption of the pressurization system is larger, so that the requirement of low-energy-consumption transportation is difficult to meet.
In summary, under the point-to-point transportation condition, how to design a transportation system to adapt to various topographic and geological conditions, reduce the construction cost, and especially under the condition of a small transportation capacity, further improve the transportation efficiency and reduce the energy consumption in the transportation process becomes a technical problem to be solved urgently by those skilled in the art.

And opening ball valves at two ends of the platform pipeline. The motor is electrified and slowly started to drive the propeller to convey the conveying mechanism to the conveying pipeline. After entering the transport duct, the propeller-driven transport mechanism is gradually accelerated to the design operating speed, for example 1 m/s.
The transport mechanism and the power device reach a terminal station and enter a platform pipeline of the terminal station. Closing ball valves at two ends of the platform pipeline. And opening the ball valve of the platform pipeline branch pipe, taking the carrying cabin out of the branch pipe, and entering the terminal station water pool. The carrying cabin is lifted out of the water pool, the cabin door is opened, the container is taken out, and the pulverized coal is discharged.
And if the goods are transported to the starting station from the terminal station, loading the corresponding goods in the container, wherein the process is the same as the loading process of the starting station.
If no goods transportation requirement exists at the end station, placing a shaped rubber bag in the container, and filling water into the rubber bag until the container meets the counterweight requirement. The container is stably loaded into the carrying cabin by using general or professional machinery such as a forklift and the like according to the positioning requirement, then positioning pins at two ends are inserted, and two cabin doors of the carrying cabin are closed. And (4) hoisting the carrying cabin into a terminal station water pool, repeating the loading procedure of the starting station, sending the transportation mechanism into the transportation pipeline, and starting the return transportation process in the transportation pipeline.
The energy consumption of the motor in the embodiment 2 is basically consistent with that of the motor in the embodiment 1, and the transportation energy consumption is only the power consumption of the motor driving the transportation mechanism in the power compartment. Under the less operating mode of freight volume, the pipeline transportation system of built-in screw has very strong adaptability, and the transportation ability is extremely strong, and the transportation is extremely nimble, implements the advantage that the effect is better. In the actual operation process, the power of the motor in the power device can be adjusted by adding or subtracting the number of the carrying cabins according to the requirement of the transportation volume, so that the requirement of the transportation volume change can be flexibly adapted.
Example 3
As shown in fig. 7, a counterweight cabinet 29 is provided in the power compartment. The counterweight housing 29 is connected to the transport pipe 7 by a pipe. The pipeline is provided with a pump. Wherein, the pipeline is a water pipe 30, and the pump is a water pump 31. The counterweight housing 29 is intended to be filled with a suitable amount of water to keep the power pod stable during transport when the transport mechanism is transported in the horizontal transport duct 7.
As shown in fig. 8, when the transportation mechanism is transported in the transportation pipeline 7 at the downhill section, the counterweight housing 29 is filled with water, so as to increase the average density of the transportation mechanism and further reduce the energy consumption of the power plant at the downhill section; when the transportation mechanism is transported in the transportation pipeline 7 at the uphill section, the counterweight cabinet 29 is emptied, so that the average density of the transportation mechanism is reduced, and the energy consumption of the power device at the uphill section is further reduced.
For example, a relatively low-point V-shaped topographic condition is formed between the starting station and the terminal station, and the purpose of further energy conservation can be achieved by intelligently controlling the counterweight cabinet.
A counterweight cabinet and a water pump are arranged in the power cabin. Under the condition of half-load in the counterweight cabinet, the integral volume weight of the capsule is 9.8KN/m3. After entering the main transportation pipeline from the starting station, the pipeline is in a downhill state, at the moment, a valve on the pipeline connecting the counterweight cabinet and the transportation pipeline is opened, and water in the transportation pipeline is injected into the counterweight cabinet until the counterweight cabinet is fully loaded. At the moment, the total volume weight of the power cabin per se becomes more than 9.8KN/m3. For example, the total volume weight of the power cabin is19.8 KN/m310.0 KN/m in the total volume weight of the power bin3The power of the transportation mechanism advancing along the pipeline of the downhill is formed, and the partial power is combined with the power of the transportation mechanism to jointly drive the goods to advance.
After reaching the low point of the V-shaped terrain, the transportation pipeline is changed into an uphill road section. At the moment, the water is discharged by a water pump, and the water in the weight distribution cabinet is discharged into a conveying pipeline until the weight distribution cabinet is unloaded. At this time, the transport mechanism itself becomes less than 9.8KN/m in total volume weight3. For example, the total volume weight of the power bin is 4.8 KN/m3And the total volume weight of the power cabin is larger than 4.8 KN/m35.0 KN/m3Buoyancy is created which becomes the motive force for the transport mechanism to travel within the pipeline along the uphill slope. The partial power is combined with the power of the transportation mechanism to drive the goods to move forwards together.
If the terrain is W, the self volume weight can be changed by repeatedly filling and draining water through the counterweight cabinet in the power cabin, so that the transportation mechanism can repeatedly carry goods from the starting station to the destination station.
