Detailed Description

When a moving object needs to pass through a solid, people adopt a method of firstly punching and then passing in order to overcome the blocking effect of the solid; for example, when a car or a train passes through a mountain, a tunnel is excavated and supported by a shield machine and then passes through the tunnel.

In the fluid medium, although the moving object can pass through the fluid medium, the motion resistance is increased along with the multiplication magnitude of the speed, the higher the speed is, the larger the resistance is, and the motion speed of the object is greatly inhibited.

The essence of the motion resistance is: because the fluid invades into the space due to the movement of the object, the fluid medium can not avoid to generate a blocking force to the movement of the object; the elimination of the resistance is to eliminate the environmental conditions caused by the blocking force caused by the mutual spatial conflict between the moving object and the fluid medium.

The conception principle of the utility model is as follows: the fluid media such as water and air are treated the same as the solid media, when the moving object moves in the fluid media, a channel is opened for the moving object, the fluid media which obstruct the movement of the object are removed and shunted, convection is realized between the moving object and the fluid media in a space interchange mode, thereby eliminating and resolving the environmental condition which forms the blocking force, and being enough to reduce the resistance of the fluid media to the moving object.

Referring to fig. 1, 2 and 3, the energy-saving water absorption ship provided by the utility model, which can reduce the resistance of the running reclaimed water to the ship body and improve the ship speed, is provided with the rectangular groove bodies 2 at the bottom and two sides of the ship body 1, the ship body 1 is embedded in the rectangular groove bodies 2, water absorption channels 4 are formed between the bottom and two sides of the ship body 1 and the rectangular groove bodies 2, and a plurality of propellers 3 for pumping water are arranged in the water absorption channels 4; the underwater part of the whole ship body is changed into a water pump type water absorption shield machine; the water absorption channel 4 formed by the rectangular groove body 2 and the ship body 1 is equivalent to a portable supporting tunnel built for the ship body 1, and a temporary transient channel is opened for the water medium; supposing that if the water medium is treated as solid sandy soil, the propeller rotates to do work, and the working principle of the water-absorbing shield machine is as follows: the method has the advantages that the method not only can punch and tunnel in sandy soil (absorb water from the front), but also can discharge dregs to propel the sandy soil (pump water backwards), and can support the sandy soil in time (the groove body serves as a portable supporting tunnel). Therefore, the ship body can smoothly pass through the water without disturbing other water bodies except the trough-shaped body, the energy of pushing and discharging the water body medium blocked in front of the ship body is saved, and the design goal of energy conservation and speed increase is realized.

In the preferred embodiment of the present invention, the number of the propellers 3 is six, four are disposed side by side between the bottom of the hull 1 and the rectangular trough body 2, and the other two are disposed between the two sides of the hull 1 and the rectangular trough body 2.

The utility model thoroughly changes the structure of the ship body, a plurality of propulsion propellers are respectively arranged at the bottom and two sides of the ship body to pump water from front to back through the water absorption channels, so that the water flows through the middle of the ship body from front to back, convection can be generated between the ship body arranged in the middle and the water bodies on two sides, and the resistance of the water to the ship body is reduced; the utility model discloses a beat whole hull and cause a huge suction pump, promote the hull to go forward. When the propulsion propellers arranged at the bottom and two sides of the water absorption channel in a certain array rotate, a huge flow of water is sucked from the water absorption channel opening at the front end of the ship body and then pumped out backwards from the bottom and two sides through the water absorption channel; the water flows from front to back and the ship moves from back to front. The drag reduction principle is that the water body and the ship body are replaced in space, so that the resistance of water to the ship body is reduced, and the drag reduction device is named as follows: a water absorption ship.

The utility model adds the groove body at the bottom of the ship to form a water suction channel, and the groove body bears the pressure of the lateral water body to play a role of supporting the tunnel; the underwater part of the ship body is transformed into a structure of a water pump, and when the propeller rotates, the water media at the front end and the rear end form pressure difference to push the ship to advance; the water body blocked in front of the ship is removed and shunted, so that the resistance of water to the ship is reduced, and the ship body is as smooth and unobstructed as a train passing through a mountain tunnel when passing through the water body medium.

Compared with the method that the ship is pushed to sail by the existing commonly used propeller thruster, the propeller not only pushes the ship but also pushes away the water body blocked in front of the ship body, so that the ship can advance; the utility model works in a way of absorbing water in front of the ship, combines two works of pushing the ship body forward and pushing away the water medium blocking the ship body to move, and finishes the two works together; the ship can advance only by pumping water, the pumping water also becomes a technical means for eliminating resistance generated by water media, the water drainage obviously increases the movement speed of the ship body, improves the efficiency, achieves the aim of energy conservation, and has obvious practical effect and no wider application prospect.

People often do not see fluid media such as air or water; the tunnel cannot be excavated, dredged and supported like a solid to be treated so as to reduce resistance and ensure that a moving object smoothly passes through the water; the thrust is increased only by one in a firm manner, and the object is subjected to 'hard collision' in an environment with extremely high fluid pressure difference resistance caused by the self movement in an aqueous medium; the result is that a large amount of energy is wasted and consumed, and the desired effect of increasing the speed cannot be desirably achieved.

In water, because the rotating speed of the propeller is too high, cavitation can be caused, blades of the propeller are damaged, and therefore, the increase of the thrust is limited, so that the ship can only crawl slowly in water; the design of the utility model is that the thrust is increased by increasing the number of the propellers in the water suction channel, and the cavitation phenomenon is ingeniously bypassed; due to the change of the thought, the hard pushing and immovable pushing practice is finished.

The present invention and the technical contents not specifically described in the above embodiments are considered to be the same as the prior art.

The above is only the specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto, and the scope of the present disclosure should be subject to the protection scope of the claims.
