Description
Technical Field
[0001] The utility model relates to the technical field of hydroelectric power generation, in particular to a pressure difference turbine. Background Art
[0002] The growth of world population has increased the demand for energy to meet the various needs of the world population.
[0003] New energy production methods are limited to clean energy production methods such as wind power, hydropower, solar power, and nuclear power.
[0004] These clean energy production methods also include the tidal turbine sector, which has seen an increase in use in recent years following several advancements in the field.
[0005] Currently, the most developed tidal turbines are marine tidal turbines designed for use in oceans and seas, but the generally low speed of ocean currents limits the popularization of this clean energy production method.
[0006] River turbines were developed for rivers, which offer higher speeds but low flows, making widespread use difficult given the low energy production.
[0007] Therefore, there is an urgent need for a turbine based on the Torricelli principle, which improves energy conversion efficiency and stability by utilizing the pressure difference of water inside and outside the main chamber and optimizing the water flow path. Utility Model Content
[0008] In order to solve the problems of the prior art, the utility model provides a pressure difference turbine.
[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions: a pressure difference turbine, comprising a circular main chamber, the top end of the circular main chamber is provided with an upper surface, the bottom end of the circular main chamber is provided with a lower surface, one side of the circular main chamber is provided with a side surface, the upper surface is provided with an opening, the lower surface is provided with a discharge pipe, and the side surface is provided with an inlet pipe;
[0010] A water inlet is provided at one end of the inlet pipe, a turbine and a generator are fixedly connected inside the one end of the inlet pipe, the axis of the turbine is fixedly connected to the main shaft of the generator, an opening is provided at the top of the inlet pipe, the opening is located on one side of the generator and inside the circular main chamber, and is used to divide the circular main chamber into two areas, an outer area and an inner area, a pressure pipe is fixedly connected at one end of the inlet pipe, a water outlet is fixedly connected at one end of the pressure pipe, a drainage inlet is provided at the inner top end of the discharge pipe, a drainage outlet is provided at the inner bottom end of the discharge pipe, a check valve is fixedly connected to the bottom end of the drainage outlet, so that water can only flow in one discharge direction, and the inner wall diameter of the inlet pipe is larger than the inner wall diameter of the discharge pipe;
[0011] The present application allows to give a certain velocity to the water, using the Torricelli principle, by means of a pressure difference between two environments, one of which is underwater at a given depth and the other in the open air. According to a first characteristic, the lateral surface of the circular main chamber allows the entry of water, in this inlet pipe a turbine will be placed, and due to the movement generated by this pressure difference, its velocity will be calculated by the Torricelli principle, and the water will be discharged through another pipe, this time placed on the lower surface of the circular main chamber. The lower opening of the pipe will be equipped with a non-return valve, and the flow of water entering the circular main chamber will be greater than the force exerted by the pressure of the water under the circular main chamber, allowing the water to be evacuated. The blades of the turbine form a circle with an axis of rotation parallel to the velocity of the water, which helps to increase the mechanical power of the tidal turbine, and the pressure difference between the two environments greatly increases the velocity of the water, generating more energy.
[0012] Preferably, the water inlet is used for water to flow in and pass through the inlet pipe, thereby driving the turbine to rotate, and converting mechanical energy into electrical energy through the generator.
[0013] Preferably, the opening is used to generate a pressure difference between the inside and outside of the circular main chamber and divide it into two areas.
[0014] Preferably, the water outlet and the axis of the discharge pipe are parallel to each other, and the water outlet and the discharge pipe are concentric.
[0015] Preferably, the axis of the water inlet is parallel to the direction of the river in which the water turbine is placed.
[0016] Preferably, one end of the discharge pipe is fixedly connected to an extension plate for forming a low-pressure area at the drainage outlet to drain water.
[0017] Preferably, a plurality of inlet pipes are provided on the side of the circular main chamber, and a turbine and a generator are arranged inside each of the inlet pipes to generate more energy.
[0018] The beneficial effects of the utility model are:
[0019] 1. The utility model realizes continuous suction and discharge movement by dividing into two environments, thereby ensuring the stability and reliability of power generation; at the same time, the setting of key components such as check valves also ensures the unidirectional flow of water, avoiding problems such as backflow, and further improving the stability and safety of the equipment. It can efficiently utilize natural water flow to generate electricity without the need for external energy input, and has the characteristics of energy saving and environmental protection. In natural environments such as lakes and rivers, the device can work continuously and stably, providing clean and renewable energy for the local area. It does not produce any harmful gases or waste during operation, and relies entirely on natural water flow to work. Therefore, it has minimal impact on the environment, helps reduce dependence on traditional energy, reduces carbon emissions, and promotes sustainable development;
[0020] 2. The utility model is applicable to a variety of water environments, whether lakes or rivers, and can effectively use natural water flow to generate electricity. This wide adaptability enables the pressure difference turbine to be used in different regions and climate conditions, providing strong support for local energy supply;
[0021] 3. The pressure difference turbine has a simple design, relatively low manufacturing cost, and is relatively easy to maintain and manage. This economical and practical feature makes the pressure difference turbine a renewable energy power generation equipment with wide promotion value, especially suitable for application in remote areas or areas with energy shortages.

[0025] Embodiment 1: Figure 1 A pressure difference turbine is shown, which is suitable for use in lake waters. The device includes a circular main chamber 1, whose upper surface 2 is open, and a discharge pipe 12 of a specified diameter is provided at the bottom 4. An inlet pipe 5 is provided on the side 3 of the circular main chamber 1. The inlet pipe 5 has a water inlet 6 and a turbine 7 connected to a generator 8. There is an opening 9 at a certain distance after the turbine 7 and the generator 8 in the circular main chamber 1, which is used for the pressure difference between the outside and the inside of the circular main chamber 1 and divides the device into two environments. From this opening 9 follows a pressure pipe 10, and a water outlet 11 is provided at the end of the pressure pipe 10. There is a discharge pipe 12 on the bottom 4 of the circular main chamber 1, and its upper part is located in the circular main chamber 1 and is provided with a drainage inlet 13. The lower part of the discharge pipe 12 located outside the circular main chamber 1 is provided with a drainage outlet 14, which includes a check valve 15, which only allows water to pass in one discharge direction, so water cannot enter through the discharge pipe 12. The diameter of the inlet pipe 5 must be larger than the diameter of the discharge pipe 12.
[0026] The device is immersed in water so that the upper surface 2 remains above the water, where the water inlet 6 of the inlet pipe 5 allows water to pass through the opening 9 on the inlet pipe 5 at a speed obtained by the Torricelli principle. This water then turns the turbine 7, generating mechanical energy, which is then converted into electrical energy by the generator 8. Once the water has turned the turbine 7, it passes through the pressure pipe 10 to the water outlet 11, which in turn allows the water to fall into the drainage inlet 13 of the discharge pipe 12. The force of the water when it reaches the check valve 15 located on the drainage outlet 14, obtained due to the head down, but the large flow of water from the pressure pipe 10, will be greater than the force exerted by the water outside the check valve 15, without filling the discharge pipe 12 and the circular main chamber 1; therefore, we have a continuous cycle divided into two environments, the first environment is from the water inlet 6 of the inlet pipe 5 through the turbine 7, the generator 8 and the opening 9, and the second area is from the pressure pipe 10 through the water outlet 11, the drainage inlet 13 of the discharge pipe 12 to the check valve 15 located on the drainage outlet 14, so this cycle makes it possible to continuously generate clean and stable electrical energy through this continuous suction and discharge movement.
[0027] Embodiment 2, as Figure 2 The pressure difference turbine shown is suitable for use in river waters. Compared with the first embodiment, in this embodiment, an extension plate 16 is fixedly connected to one end of the discharge pipe 12 to form a low pressure area at the drainage outlet, thereby facilitating drainage.
[0028] In summary, the pressure difference turbine described above is uniquely designed and suitable for use in lake and river waters. Its working principle is based on the Torricelli principle, which introduces water flow through the inlet pipe and uses the water flow to rotate the turbine to generate mechanical energy, which is then converted into electrical energy by the generator. The design of the device cleverly divides the device into two environments, forming a continuous suction and discharge movement, thereby achieving continuous and stable generation of electrical energy.
[0029] In the embodiment used in lake waters, the turbine introduces water through the inlet pipe, and after the water flows through the turbine to rotate the generator, it is discharged into the discharge pipe through the pressure pipe and then discharged back into the water body. The check valve design in the discharge pipe ensures that water can only flow in one direction, preventing water from flowing back into the device.
[0030] In the embodiment used in river waters, an extension plate is added at one end of the discharge pipe to form a low-pressure area, thereby further optimizing the drainage effect to adapt to the more turbulent water flow in the river environment.
[0031] This pressure difference turbine is simple in design and highly efficient. It can use natural water flow to generate clean and stable electricity, which is of great significance for the development and utilization of renewable energy. At the same time, its adaptability to different water environments also increases its flexibility and extensiveness in practical applications.
