Description

Technical Field

[0001] The present invention is another type of hydraulic machine that relies on hydraulic head or flow velocity to generate gravity or thrust, driving the folding impeller in the annular pipe body to drive the chain pulley to continuously rotate for power generation or power output. Background Art

[0002] Currently, most of the devices that use water power to output power externally are vane hydraulic turbines. The biggest and most common defect of these devices is that they require a large amount of construction sites and a large amount of water sources. They all use large amounts of water to flush and push the displacement of the blades to do work externally. Therefore, it is required that the water source is sufficient, the head is large, and the diversion is long. This has caused a lot of energy consumption and loss in such hydraulic turbines. Moreover, the contact time between the impeller and water is short, the work efficiency is low, and the effectiveness of the water ends immediately after doing work, and the energy disappears instantly, resulting in a great waste of natural resources.

[0003] The present invention is a device that can be installed and used according to local conditions. It can utilize the gravitational head or flow velocity thrust of water over a long distance to directly drive the folding impeller chain pulley to output electrical energy or rotational power externally. Compared with the existing hydraulic turbines, it has unprecedented high performance. It only needs to fix its position to be installed and used, without occupying construction sites. Its structure is simple, energy-saving and environmentally friendly, with low cost, light weight, and is very convenient for handling, installation and disassembly. This greatly reduces the infrastructure expenditure and construction cost. Therefore, it has wide adaptability and flexibility, and has a stable effect whether for power generation or power output.

[0004] Currently, no public information about such folding impeller hydraulic machines has been retrieved.

[0005] There are numerous rivers, lakes, gullies and streams across the vast land, and these water resources are being wasted every day.

[0006] In order to make full use of the water resources in gullies, streams, large rivers and lakes, from high water levels with large heads to low water levels with small flows, a portable folding impeller hydraulic machine that can generate effective energy immediately after installation has been invented. As long as there is water flow velocity, it can drive the superimposed impeller chain rollers in the annular pipe to rotate, drive the generator to generate electricity, and convert the effective water power into power. This is the purpose of the present invention.

[0007] A set of structural features of the present invention are as follows: a hollow pipe in the shape of a circular ring column, made of non-magnetic material. At the protruding end of the ring pipe is a water inlet flange, which can be docked with other external water inlet fittings. The flange extends into a tapered circular flat nozzle, and a flow regulating valve and an impact buffer are installed at this position. The channel of the ring pipe is in the shape of a circular ring column, and the side of the water outlet is a large-bellied slow-flow cavity, which then extends into a tapered elliptical cavity until the water inlet nozzle. On the other side of the buffer large-bellied cavity is a short pipe flange, which is flange-connected to the water outlet of the ring pipe. The water outlet pipe is a bent pipe that is directly connected to the tapered pipe flange, and then is connected to the water inlet flange of the next set of ring pipes. In this way, multiple ring pipes can be connected in series. Inside each ring pipe, a folding impeller and a groove plate are installed, which are fixed on the chain pulley in series with a pin shaft, and are interlocked around the inner wall of the ring pipe and can rotate and slide freely; a circle of rectangular permanent magnets are inlaid in the groove plate, and their adjacent two poles repel each other, corresponding to a circle of stator silicon steel induction coils on the inner side of the outer wall of the ring pipe. The stator silicon steel induction coils are sealed and wrapped with epoxy resin on the inner side of the outer wall of the ring pipe, and are externally sealed with a protective cover, rubber pads and waterproof materials.

[0008] The described reducing flange of the bent pipe is characterized in that: the larger flange is connected to the short pipe bent pipe, and the bent pipe is directly connected to the tapered pipe to form a longer cavity pipe leading to the smaller flange.

[0009] The structural features of the described folding impeller are as follows: the impeller blade surface is slightly smaller than the inner diameter of the ring pipe, and is in the shape of a circular concave surface. There is a foldable groove on the contour edge of the impeller, which is locked between the chain pulleys with a pin shaft. At the other end of the contour edge, a support pulley is fixed. The whole impeller takes the pin shaft as the fulcrum and can fold freely.

[0010] The described chain pulley is characterized in that: two chains are fixed on the chain pulley in parallel with a pin shaft. Every other pin shaft is a long pin shaft. Each long pin shaft clamps two rollers and the groove plate. At every length with the diameter of the impeller circle, a folding impeller and the groove are riveted together with the rollers of the chain pulley with a long pin shaft. The diameter of the rollers is slightly larger than the groove plate and the impeller contour, so that it can rotate freely around the inner wall of the ring pipe.

[0011] The described permanent magnet is characterized in that: it is rectangular. The N poles and S poles of the rotor permanent magnets are arranged alternately in the circumferential direction. At the same radial position of the rotor magnetic poles, the magnetic field polarities of the outer circumference and the inner circumference of the rotor are opposite. The rectangular permanent magnets are inlaid and fixed on the groove plate of the chain pulley, corresponding to the stator silicon steel induction coils on the outer wall of the ring pipe.

[0012] The stator described above is characterized in that: the stator silicon steel induction coil is fixed on the inner side of the outer wall of the annular pipe. The inner side of the stator is provided with stator slots, and the shape of the stator slots is pear-shaped. Distributed windings are embedded in the slots. The stator slots of the stator are set according to the size of the inner side of the annular pipe. Similarly, concentrated enameled wire windings with a set number of turns evenly divided are sleeved on each layer of the stator yoke made of magnetic conductive material.

[0013] The flow regulating valve described above is characterized in that: the regulating handle is fixed on the outer wall of the annular pipe and is fixed to the sprocket, positioning rod, spring, and connecting shaft with screws. The connecting shaft on the inner wall of the annular pipe is fixed to the control gate with a keyway, and the control gate is arranged corresponding to the nozzle throat.

[0014] The impact buffer described above is characterized in that: the impact buffer is arranged at the water spraying port on the inner wall of the annular pipe and is composed of a fixed seat, an umbrella-shaped ejector rod, a spring, and screws, corresponding to the pulley at the top edge of the impeller, to relieve the sudden impact of the impeller.

[0015] The two groups of annular pipes of the present invention have the same technical principle and their structures are mutually deformed forms. The overall structure is a long circular and elliptical cylindrical hollow annular channel. At the inlet flange, a longer annular pipe channel is connected, and the outlet channel flange is directly connected. Next to the outlet, the curved semi-circular section gradually flattens into an elliptical elbow shape and is connected to the outlet channel in a "T" shape; the elliptical elbow is then connected to a longer elliptical straight pipe, and the extended curved semi-circular section elliptical elbow gradually becomes cylindrical. The elbow and the inlet channel flange communicate with each other in a "T" shape, and an impact buffer is installed at the position corresponding to the support pulley. A folding impeller and a chain pulley are installed inside the annular pipe, and they are closely interlocked and can freely rotate and slide around the inner cavity of the annular pipe wall. At the same time, the chain on the chain pulley engages with the gear disc arranged on the elliptical channel, and power is output by the gear shaft for power generation or as power use.

[0016] The sprocket shaft of the two groups of annular pipes described above is characterized in that: the sprocket shaft passes through the center of the sprocket and is connected as a whole, and the sprocket is engaged through the chain pulley and then the shaft outputs efficiency externally.

[0017] The progressive effect of the operation process of the first group of loop pipe technologies of the present invention lies in: according to the basic construction conditions of the terrain and landform, a water source with a certain water flow drop is selected, and various ways can be adopted for water diversion, which can be freely and conveniently connected to the inlet flange of the present invention. When the gate or valve is opened on the periphery to divert water into the loop pipe, due to the push of the gravity of water, the folding impeller connected body in the loop pipe is forced to continuously move in a circular motion around the loop pipe. A flow regulating valve and a nozzle throat are arranged at the water inlet to accelerate the flow rate. When the folding impeller is impacted by the incoming water, a support pulley is installed at the top edge of the impeller. After hitting the impact buffer, it extends and opens. Since the roller lengths and diameters of the support pulley and the chain pulley of the folding impeller when unfolded are larger than the inner diameter of the loop pipe, the loop pipe passage is blocked, resulting in a pressure difference between the front and back inside the loop pipe, forcing the folding impeller connected body to continuously move forward in a circular motion. When the folding impeller connected body passes the extended position of the water outlet, it will be squeezed by the gradually shrinking loop pipe wall, suppressing the folding of the impeller and the chain pulley, reducing the resistance and moving forward. When it runs to the water inlet, the folding impeller is impacted by the incoming water at the water inlet, and the folded impeller extends and opens again, blocking the loop pipe passage, forcing the chain pulley and the permanent magnet on the groove plate to reciprocate in a circular motion.

[0018] Since the magnetic lines of force of the permanent magnet do not change with water and non-magnetic insulating material bodies, the magnetic lines of force of the permanent magnet can freely pass through the wall layers of these materials; when the chain pulley and the permanent magnet on the groove plate are forced to move in a circular motion, the magnetic lines of force emitted by the permanent magnet are captured and cut by the stator silicon steel induction coil outside the loop pipe, immediately generating electricity and directly outputting effective electric energy to the outside.

[0019] One layer of loop pipe is a single generator, and multiple layers of loop pipes can be combined into one body by using other new technologies such as series or parallel connection, which is a high-power generator. Therefore, this generator has high efficiency, simple structure, small occupied space area, low material cost, and low requirements for manufacturing process. It is especially suitable for use in large numbers of small and medium-sized hydropower or small and medium-power occasions.

[0020] The operation process and progressive effect of the second group of loop pipe technologies of the present invention are basically the same as those of the first group above.

[0021] According to the small drop and slow flow rate of small ditches, small rivers and streams, especially the extremely small flow rate of rivers, it is only possible to improve its efficiency by changing its structure, lengthening the working time, increasing the stress area, and increasing the dynamic rotation speed.

[0022] When the water from the surrounding rivers and gullies flows into the annular pipe through the flared opening, the folding impeller is impacted by the incoming water flow velocity, and the folded impeller will be forced to unfold. Since the support pulleys are installed at the top edge of the folding impeller and the roller length diameter of the chain pulley is larger than the inner diameter of the annular pipe, it supports the unfolded impeller surface to block the annular pipe channel. At this time, a water level difference is generated inside the annular pipe, forcing the folding impeller and the chain pulley to roll forward and perform circular motion together. When the folding impeller runs at the tapered elliptical elbow, it will be squeezed by the tapered wall of the annular pipe, forcing the folding impeller and the chain pulley to fold to reduce resistance and move forward. When it passes through the elliptical channel and comes to the water inlet again, the folding impeller is impacted by the incoming water, and the folded impeller unfolds again to block the annular pipe channel, and reciprocates to perform the above circular motion; at this time, the sprocket of the sprocket shaft installed on the upper part of the elliptical channel engages with the chain pulley, thereby driving the sprocket shaft to rotate for external generator power generation or power output.

[0035] Preferably, the stator silicon steel induction coil 7 is characterized in that: it is fixed on the inner side surface of the outer wall of the annular pipe 1. The groove of the stator silicon steel induction coil 7 is a pear-shaped groove, and a distributed winding, which is an induction coil, is embedded in the groove. The stator silicon steel induction coil 7 sets the stator slots according to the size of the inner side surface of the annular pipe 1. Similarly, a concentrated enameled wire winding with a set number of turns evenly divided is sleeved on each layer of the stator yoke made of magnetic conductive material, and it is sealed and wrapped with epoxy resin on the inner side of the outer wall of the annular pipe 1. The outer layer is waterproof, sealed and insulated with a sealing protective cover 8 and a rubber cover plate.

[0038] As Figure 4 The annular pipe 1 is in the second embodiment, and its structure is: an integral long strip-shaped elliptical annular cavity. Slideways a6 are respectively inlaid on the inner and outer tube walls of the size. The water inlet flange a1 is connected to a longer working channel a9, which is linearly communicated with the water outlet flange a2. A curved semi-circular cylindrical pipe that gradually shrinks into an elliptical elbow a3 is connected in a "T" shape beside the water outlet, and is communicated with a longer elliptical return channel a8 with an elliptical cross-section. Then it extends and gradually expands from an ellipse into a circular channel a4, which is communicated with the working channel a9 of the water inlet in a "T" shape.

[0039] Preferably, as Figure 4 The sprocket shaft 9 is characterized in that: the sprocket shaft 9 is fixed between the return channel a8 of the annular pipe 1 and the elliptical gradually expanding circular channel a4 by the generator fixing clamp 17.

It is engaged with the sprocket through the chain on the chain pulley 4 and then the shaft outputs the efficiency externally. Specific Embodiment 1

[0041] As Figure 1 、 2As shown in Figure 3, the ring pipe 1 is a circular hollow cylinder. The protruding part of the ring pipe 1 is an inlet pipe flange a1, which can be connected with the flanges of other external water inlet accessories. The other side is a slow flow channel a5 of the ring pipe 1, which is connected to the water inlet flange a1 of the next ring pipe 1 by the outlet flange a2 and the elbow flange 3. In this way, multiple ring pipes 1 can be connected. A folding impeller 2 is installed in each ring pipe 1, and is fixed together by a chain roller 4 and a groove plate 5 with a pin d3, surrounding the ring pipe. 1 cavities are linked together, so that the multiple folding impellers 2 can rotate freely in the slideway a6 in the cavity of the ring tube 1; a rectangular permanent magnet 6 is fixed in the groove plate 5, and the permanent magnet 6 is arranged in two adjacent levels to repel each other. The stator silicon steel induction coil 7 is corresponding to the permanent magnet 6 on the inner side of the ring tube and is sealed and wrapped on the inner side of the ring tube 1 with epoxy resin. Since the water flowing in the ring tube 1 is used as the coolant, there is no heat generation phenomenon, and the outside is sealed with a protective cover 8, a rubber pad and a waterproof material.

[0042] Working principle: According to the terrain and infrastructure conditions, a water source with a certain water drop is selected, one or more fixed piles 13 are driven into the river waterway, and the position is fixed by the clamp j3 on the fixed pile 13, so that the main hook d1 and the auxiliary hook d2 are installed to fix the ring pipe 1, and the number of ring pipes 1 on the fixed pile 13 can also be increased and replaced at will.

[0043] The water diversion connection method can be a pipeline diversion method, a reservoir siphon method, a damming gravity method, a damming cofferdam diversion method, all of which can be freely and conveniently connected to the water inlet flange a1 of the present invention. When the peripheral diversion water is injected into the annular tube 1, due to the gravity flow rate of the water, when the folding impeller 2 rotates to the water inlet, the impeller b1 is impacted and opened by the incoming water, so that the support pulley b2 on the top edge is also unfolded. When the support pulley b2 is unfolded, the diameter between the support pulley b2 and the roller b6 is slightly larger than the inner diameter of the annular tube 1, and the channel of the annular tube 1 is blocked to maintain the unfolded state, forcing The folding impeller 2 pushes the chain roller 4 to move forward only along the channel of the ring tube 1. All the folding impellers 2 in the channel of the ring tube 1 rotate tightly around the cavity of the ring tube 1 in this way, and at the same time force the groove plate 5 and the permanent magnet 6 on the chain roller 4 to do circular motion together. Since the magnetic lines of force of the permanent magnet 6 do not change in water or non-magnetic insulating material, the magnetic lines of force can freely pass through the wall layer of the ring tube 1 made of non-magnetic insulating material, and be cut by the stator silicon steel induction coil 7 outside the ring tube 1, immediately generate electrical energy, and directly output effective electrical energy to the outside.

[0044] Each layer of annular pipe 1 is a single generator 17, and multiple layers connected in series or in parallel form a high-power generator 17, so the hydraulic machine has high power generation efficiency. Specific implementation method 2

[0046] like Figure 2 , 3As shown in FIG. 4, due to the vast land with numerous rivers and lakes, gullies and streams are everywhere in the mountainous areas. The water volume of these small ditches and streams is not large, the drop is small, and the flow rate is slow. In particular, the water in rivers and lakes is mostly flowing water and it is difficult to have a drop. It is difficult to increase the speed of the generator 17. Some improvements must be made in the structure to increase the running length of the ring pipe 1 and the thrust of the water flow. Therefore, on the basis of the above-mentioned embodiment 1, it is deformed into a long annular pipe, and the return channel a8 of the ring pipe 1 is changed to an elliptical channel with a long cross section. The power channel a9 is changed into a long strip section into a cavity column channel, one end of which is communicated with the circular tapered elliptical channel a3 and the water outlet flange a2 in a tee manner, and the other end is communicated with the elliptical gradually expanding circular channel a4 and the water inlet flange a1 in a tee manner. At the same time, the chain pulley 5 made of anti-corrosion material is engaged with the toothed disc shaft 9 installed in the return channel a8 of the ring tube 1. The toothed disc shaft 9 is also conveniently connected coaxially with the generator 17 to output electrical energy. A pulley can also be installed on the toothed disc shaft 9 to convert it into rotatable mechanical energy.

[0047] The working principle of the second specific implementation mode is basically the same as that of the first specific implementation mode.

[0048] For the stream water source introduced into the small ditch or river, the gravity cofferdam water injection method is adopted. According to the terrain, the bell-mouth flange 10 is facing upward to the incoming water, the return channel a8 of the ring pipe 1 is on the top and the working channel a9 is erected at the bottom, and then the water outlet is close to the depression, and the ring pipe 1 is fixed by piling on both sides. When the incoming water has a certain drop or flow rate, it can be started and used.

[0049] For the flowing water source introduced into the big rivers, the bell-mouth flange 10 is directly aimed at the upstream water direction, and the fixed rope 14 towing technology is adopted to put a long floating bucket 15 on both sides of the ring pipe 1, so that the return channel a8 of the ring pipe 1 stands on the water surface, and there is no water resistance during operation; the working channel a9 floats in the flowing water of rivers, lakes and reservoirs, and can be washed and flowed by the flowing water.

[0050] According to the topography and the size and amount of the incoming water, the diameter and length of the working channel a9 of the annular tube 1 can be increased and lengthened, which is also an implementation method.

[0051] The working principle of the second implementation mode is as follows: in the annular tube 1, the folding impeller 2 is riveted to the connecting rod chain 4 with a pin shaft d3, and is linked together around the cavity of the annular tube 1; when the folding impeller 2 is pulled by the connecting rod chain 4 and reaches the water inlet, it is thrust by the incoming water, and the impeller b1 will automatically unfold, blocking the channel of the annular tube 1 to generate a force difference, thereby rotating reciprocatingly; when the chain pulley 4 comes to the return channel a8 of the annular tube 1, it engages with the toothed disc on the toothed disc shaft 9, and the toothed disc shaft 9 is connected to the external generator 17, thereby pulling the generator 17 to operate and generate electricity, and the pulley on the toothed disc shaft 9 can also be replaced to drive the mechanical operation, which is particularly suitable for the development of the vast rural economy, and can both generate electricity and serve as an electric motor.

[0052] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Without departing from the concept of the present invention, several alternatives or modifications can be made to these described embodiments, and these alternative or modified forms of the same origin should all be regarded as belonging to the protection scope of the present invention.
