Description

New use of triangular prisms

The invention relates to the application of a triangular prism in fluid mechanics, in particular to the application of a triangular prism in windproof, dredging, protecting, blocking a tsunami and blocking the movement of sand dunes. Background technique

At present, the desert environment is deteriorating. There are sandstorms in northern China, which seriously affect people's lives and economic development. In order to improve the environment and prevent desert migration, people have worked hard for it. However, the effect is not obvious.

Existing wind protection methods mainly include planting windbreaks, pulling wind nets, and building wind walls. Planting windbreaks mainly includes planting trees such as poplars and jujubes. However, their growth is slow, the period is long, and the effect is slow. In addition, the desert environment is bad and the survival rate is not high. Methods such as pulling wind-proof nets and wind-proof walls, although they work in the short term, have a short service life, a large amount of construction work, and high cost.

Rivers involve many economic and social interests such as irrigation, shipping, and drinking water. As the upper reaches of the river are constantly washed away by silt, siltation is formed in the river channel, especially in the docks, bridges, etc., resulting in siltation of the river, the riverbed is constantly being raised, and even some rivers become suspended rivers. It is easy to cause serious problems such as decision-making and downstream interruption. It also seriously affected shipping. The prior art generally uses a high pressure pump to flush the silt, but the effect is poor and the workload is large. In addition, there are also ways to remove silt by dredging. This method is more labor-intensive, inflexible, and difficult to use widely.

Lifting dams is the main means to prevent flooding. Every year, a large amount of manpower and material resources are invested in the escort. However, every time the flooding occurs, the incidents occur frequently, causing major economic losses such as flooding of fields and destruction of houses. And seriously threatened the lives and health of the affected people. The decision was mainly due to the long-term scouring of the dam, which made the dam weak, but the flood exceeded the critical pressure that it could withstand, and thus collapsed, causing a decision. At present, the common method of protection is to directly strengthen the dam, such as cement or stone reinforcement, or plant turf trees on the dam to slow the water and soil loss caused by water rushing. These methods are all started from the dam itself, the former is quite expensive, and the latter is less effective. Tsunami is generally caused by underwater activities such as underwater earthquakes, volcanic eruptions, or underwater collapses and landslides. When an earthquake occurs on the seabed, the seawater is violently undulating due to the power of the shock wave, forming a strong wave, propelling forward, and drowning the coastal zone. The current method of treating the tsunami is mainly to prevent timely avoidance. However, many tsunami cannot be accurately predicted, and even if the prediction is accurate, it will still have serious consequences. SUMMARY OF THE INVENTION The present invention solves the above problems by providing a triangular prism based on the principle of fluid mechanics.

A first object of the present invention is to provide a triangular prismatic barrier fluid for attenuating fluid flow rates.

A second object of the present invention is to provide the use of the above-described triangular prismatic fluid barrier fluid. The invention first provides for the use of a triangular prism in fluid shunting and/or choke.

Wherein, the fluid may be a gas stream, a sand stream or a water stream. The triangular prism is preferably an equilateral triangular prism.

The triangular prisms may be plural and arranged in one or more rows, wherein the first row faces the flow direction.

Moreover, the triangular prism may be a hollow or solid triangular prism. In addition, plants can be planted in hollow triangular prisms.

The triangular prismatic barrier fluid provided by the present invention is arranged in a single row or a plurality of rows of triangular prisms, wherein a corner of the first row of triangular prisms faces the flow direction. Preferably, when the triangular prisms are arranged in a plurality of rows, the side of the front and rear rows of the triangular prisms form a fan-shaped structure, or the positions of the rows of the triangular prisms are arranged in a cross. Preferably, the triangular prism is an equilateral triangular prism. The flow direction includes gas flow direction, such as air; liquid flow direction, such as water; solid flow direction, such as sand dust.

The triangular prism described above achieves the purpose of weakening the flow rate by changing the direction of the fluid. When arranged in a fan shape, when the fluid passes through the first triangular prism, the fluid is split to the sides along both sides of the triangular prism, and then the rear triangular prism changes its wind direction so that the wind follows the fan shape. Go forward until the wind is weakened. When crossed, when the fluid passes through the first triangular prism, the fluid is divided along the two sides of the triangular prism, and when it reaches the second row of triangular prisms, it continues to be divided into two sides, and the wind is blocked during travel. And offset each other to weaken.

The spacing between the triangular prisms may be set between the lengths of the sides of the 1 to 5 triangular prisms. Of course, it is not limited to such a separation distance.

The triangular prismatic fluid of the present invention can be used for windproof, dredging, protecting, blocking the tsunami, blocking the movement of sand dunes and the like.

Especially suitable for desert wind protection when used in windproof applications. The side length and height of the triangular prism can be adjusted according to the local environment. Generally, the triangular prism has a side length of 3 to 10 cm and a height of 0.10 to 2 m. Preferably, the triangular prism has a side length of 6 to 8 cm and a height of 30 to 50 cm. For places where typhoons often occur, the triangular prisms can be made taller and stronger. For example, they can be made 5~20m high and 5~10m long. The triangular prism may be hollow, the bottom of which is buried in the wet sand layer of the desert, and the interior is filled with sand. This can save costs. Depending on the local wind speed, you can choose a triangular prism made of different materials, which can be waste plastic, wood, cardboard, cement, steel, etc. While protecting the wind, it can effectively block the movement of sand dunes.

Further, the above triangular prisms can also be used for planting plants. At this time, the triangular prism can be set in a hollow or semi-hollow mode in which plants are planted. The bottom is buried in the wet sand layer of the desert, and the interior is filled with sand or a cultivation substrate, and plants are planted in the triangular prism. When planting plants, the roots of the plants should be brought to the wet sand layer. In addition, when planting plants, the seeds should be located at the wet sand layer. The plant is planted by the triangular prism, and the seed can be germinated in the triangular prism to avoid the intrusion of the wind, and the rice can be effectively resisted from the dry list and the high temperature, so that the seed is easy to germinate and grow. The triangular prism generally used for planting has a height of 10 to 50 cm, preferably 30 to 50 cm, and the sand in the triangular prism is filled to be flush with the outer dry sand, so that the interior has a certain shape suitable for seedling growth. space.

When used for planting, a single triangular prism can be used for planting, or a number of triangular prisms can be used to form a planting group.

When applied in fluid decontamination, a corner of the triangular prism faces the fluid flow, triangular prism The bottom of the body is connected to the sludge or buried in the sludge. When the fluid is split along both sides of the triangular prism, the space through which the fluid flows is compressed, causing the fluid to flow up and down along the triangular prism, and the flow velocity between the fluid passing through the triangular prism is accelerated, thereby Siltation at the bottom or sides of the prisms washes up and is carried away as the fluid flows. If the fluid flow rate is too low or at rest, the fluid can also be flowed through the auxiliary equipment, for example by a turbine.

This method of dredging is especially suitable for the cleaning of sediments in rivers, such as the cleaning of silts at piers, piers and the like. The lower end of the triangular prism can be buried in the sediment at 0.15~0.35cm.

The triangular prisms may be connected in a row by ropes and steel wires (cables) for convenient operation and reinforcement, and the ends of the rows of triangular prisms may be fixed by fixed piles. The fixed pile can be further fixed to the mobile device to facilitate moving work. In addition, the fixed pile can be moved in multiple directions, such as up and down, left and right, front and back, on the moving device, so as to adjust the position of the triangular prism and the depth of the river bed.

When applied to the guard, the triangular prism is fixed on the riverbed adjacent to the dam. The fixing method can be anchored on the river bed or a corresponding bracket for the triangular prism to facilitate fixing.

When applied to block a tsunami, the triangular prism is fixed on the shore where the tsunami often occurs. The triangular prism should be made of high-strength material and should be buried deep to resist the impact of the waves during the tsunami.

The present invention also provides a planting system comprising the triangular prismatic barrier fluid described above, in which plants are planted. The planting system can be used in deserts or in the Gobi. When planted in the desert, the walls of the triangular prism can be taken locally, for example mainly from sand (the sand is sanded by adhesive). The height of the triangular prism used in the planting system may be 5 to 诵m, and the side length may be 20 to 100 m, for example, the height is 30 m, the inner length is 48.056 m, and the plantable area is 1000 m ² .

There is a reservoir in the triangular prism of the above planting system. The outer side of the triangular prism is wound with one or more turns of the water tank, and the low end of the water tank is connected with the water storage tank, and the rainwater is connected by water. The trough is introduced into the reservoir.

In addition, the top of the triangular prism in the planting system has a closable transparent top. Moreover, the temperature in the triangular prism is adjusted by the heat pump technology; the power is supplied to the system by the temperature difference power generation, and the temperature difference power generation utilizes the temperature difference between day and night or the temperature difference between the surface and the ground.

The invention is based on the principle of fluid mechanics, and is simple and easy to operate, low in cost and good in effect, and provides an effective way for the current desert sand control, river sediment clearing, protection and protection against tsunami. In addition, the planting system of the present invention can realize the control of dust storms and adjust the atmospheric circulation through the sub-flow blocking action of the triangular prisms, thereby adjusting the environmental dryness and humidity and reducing the single enthalpy, which is a good tool for environmental improvement and desert governance.

The following examples are intended to illustrate the invention, but are not to be construed as limiting the invention. Example 1 Triangular prismatic work fluid (fan shape) As shown in Fig. 1, in this example, the triangular prismatic fluid has four rows of fluids, one corner of the first row of triangular prisms is facing the flow direction, and the a side of the first to fourth rows of triangular prisms forms a fan shape.

The triangular prism is an equilateral triangular prism with a length of 10 cm on each side and 髙 lm. The bottom is buried in the desert 15cm. The spacing between the two triangular prisms is 10 cm.

At the time of wind, when the wind passes through the barrier fluid, the wind speed is significantly weakened and the flow of sand is small. The initial wind speed was measured to be 8.3 m/s, and the wind speed was reduced to 6.4 m/s after the splitting fluid. Example 2 Triangular prismatic fluid (cross)

As shown in Fig. 2, in this example, the triangular prismatic fluid has three rows of fluids, one corner of the first row faces the fluid direction, the interval between the two triangular prisms is 30 cm, and the second row of triangular prisms is located first. Between two triangular prisms, the third row of triangular prisms is located in the middle of the projection of the first row and the second row of triangular prisms on the line, and the row spacing between the three rows of triangular prisms is two triangular prisms. Side length. The triangular prism is 2m high and has a side length of 10cm.

When the wind is passing through the wind-splitting pile in the desert, the wind speed is significantly weakened and the sand flow is small. After measurement, the initial wind speed is 9.6m/s airflow, and the wind speed is reduced after the splitting fluid

Example 3 Triangular prismatic fluid barrier (single row)

As shown in Fig. 3, in this example, the triangular prismatic fluids are arranged in a single row with a corner facing the flow direction. When the wind is blowing in the desert, when the wind passes through the wind-splitting pile, the wind speed is weakened and the sand flow is small. Example 4 Triangular prismatic barrier fluid (desert plant cultivation) In this example, the triangular prism array structure was the same as in Example 1.

The triangular prism has a side length of 6cm and a height of 30cm. The lower end is 15cm buried in the sand to reach the wet sand layer. The plant seed watermelon is planted at the bottom of the triangular prism, filled with sand and flush with the outer sand (Figure 4). ), normal watering and fertilization. Results After planting 1000 seeds, the germination rate reached 99%, the plants grew well, and the seedlings were basically dead (survival rate reached 96%). The control group grown under the same conditions (not planted in the triangular prism) died. In the same way, a triangular prism having different side lengths (3 cm, 5 cm, 8 cm) and height (20 cm, 30 cm, 40 cm) was used for planting plants, and similar effects were obtained.

The realization of this effect is mainly due to the smoke-simplification effect of the triangular prism. The smoke floor effect can be used to raise the ground gas of the desert, so that the temperature and moisture of the planting environment are improved. Example 5 Triangular prismatic barrier fluid (integrated cultivation of desert plants)

Comprehensive cultivation of desert plants can be achieved by using triangular prisms. In the desert, a rectangular prism is formed by a triangular prism. Each side of the rectangle has two rows of staggered triangular prisms, and a corner of the triangular prism realizes the purpose of blocking flow and weakens the wind speed inside the rectangle. The triangular prisms on each side have a height of 30 meters (7 meters buried underground) and a side length of 48.056 meters. They are planted in this large triangular prism (called a large greenhouse).

In the middle of the rectangular structure of the triangular prism, planting of various types of plants can be carried out to form an ecological garden. And on the basis of this can develop tourism.

In addition, a reservoir is arranged in the triangular prism body, and a water tank is wound on the outer wall of the triangular prism body, and the low end of the water tank is connected to the water reservoir (which can be used in a closed type). Since the rainfall in the desert itself can reach 100 mm, the collection of precipitation further increases the water storage capacity and solves the problem of water use.

The depth of the desert underground is 20~50 meters. The temperature is generally constant at 28 °C. In some places, the temperature below lm can be below 20 °C, and the surface temperature can reach 70~90 °C during the day. Therefore, it passes through the desert surface and the ground. The temperature difference can be realized by converting thermal energy into electrical energy and solving the problem of electricity consumption. In addition, the temperature problem of the sand shed (triangular prism) can be adjusted by the temperature of the ground. It is mainly used in heat pump technology and thermoelectric power generation technology to effectively utilize the energy of the desert. In fact, the desert itself is a large energy storage body, and its energy is very abundant. Heat pump technology can be used to adjust the temperature in the triangular prisms using the thermal energy of the desert surface or underground, and can also convert thermal energy into other forms of energy. Through the thermoelectric power generation technology, the huge temperature difference between the desert surface and the underground is used to generate electricity and supply the entire planting system. Moreover, the energy obtained by thermoelectric power generation can also be used to adjust or supplement the light source. To facilitate plant growth.

In the above comprehensive planting structure, the height of the triangular prism can be set to be 5 to 100 meters, and the side length can be set to be 20 to 100 meters, and the four sides can be one or more rows of triangular prisms. The triangular prisms may also be arranged in a shape such as a circle, an ellipse, a triangle or a polygon, or may be formed in an irregular shape depending on the location.

In addition, as shown in FIG. 5, a plurality of rows of small triangular prisms 7 can be used to form a raft (mainly splitting and blocking wind), and a plurality of large triangular prisms 8 (such as the aforementioned sand shed) are arranged on the main windward side. A functional area such as a living area 9 and a planting area 10 is provided behind the large triangular prism 8.

Planting in the desert has the advantages of no pollution, sufficient sunshine, large temperature difference, pure water source, balanced dry and humidity, high utilization of natural resources, etc. It is an excellent way to develop high-quality agricultural products and medicinal products. In addition, through the sub-restriction of the triangular prism, it is possible to control the dust storm, adjust the atmospheric circulation, and then adjust the ambient dry humidity and reduce the single enthalpy. It is a good tool for environmental improvement and desert management. Example 6 Triangular prismatic barrier fluid (channel dredging)

As shown in Fig. 6, the triangular prisms are connected by a steel wire in a row, one side of the triangular prism is kept parallel in the line, the opposite corners face outward, and the two triangular prisms are separated by a triangular prism. Long length.

The triangular prisms connected in a row are placed on the silt which is blocked by the river, and the arrangement is perpendicular to the flow direction of the water flow, so that the outward facing corner of the triangular prism faces the flow of the water. At the same time of diversion, the trapezoidal silt will also be separated from the water flow. As the sediment is gradually taken away by the water flow, the sediment will continuously reduce its height, and the triangular prism will also lower its height. Bring the bottom to contact with the sediment. This will speed up the cleaning of the silt. Example 7 Triangular prismatic fluid barrier (protective)

The splitting fluids of Examples 1, 2, and 3 were respectively fixed at the dam that was often washed by the waves (the river bed adjacent to the dam), and as a result, the wave force for scouring the dam was significantly weakened, and the degree of attenuation was compared with the triangular prism. The number of rows of body block fluid is proportional. And untrimmed triangular prisms Compared with the dam lifting of the split-resistance fluid protection, the degree of erosion damage of the dam is significantly reduced. Industrial applicability

The present invention provides a new use of a triangular prism that can be used for desert sand control, river sediment clearing, protection, and protection against tsunamis. In addition, the present invention utilizes a planting system constructed of a triangular prism to enable effective and comprehensive utilization of the desert.
