Description

Technical Field

[0001] This invention relates to a mechanical device, particularly suitable for a hydro-generator installed on a waterway. Background Technology

[0002] With social development and improved living standards, energy demand is increasing, leading to a rise in carbon emissions. People have realized that large carbon emissions contribute to the greenhouse effect and cause frequent natural disasters, making carbon emission reduction imperative. As a result, wind and solar power have become popular. However, many rivers have small drops, and the water downstream of power plants cannot be dammed for secondary use, resulting in water resource loss. Although there is a patent (patent number 201920799656.2) that can be fixed on a canal to generate electricity without building a dam, it has drawbacks. When the angle between the baffle and the bottom of the canal is greater than or less than 90 degrees, the lower end of the baffle is a certain distance from the bottom of the canal, causing water to leak directly from the lower end of the baffle, resulting in wasted water resources and low power generation efficiency. Furthermore, it has disadvantages such as large circular plate area, weak wind resistance, and inconvenient transportation. Summary of the Invention

[0003] To overcome the shortcomings of the above problems, the present invention provides a water turbine generator for a water channel. In order to reduce the waste of water resources and improve the power generation efficiency, the water turbine generator for the water channel is equipped with an automatic sluice gate on the partition plate. In order to increase the wind resistance, the original two large circular plates are modified into a rotor, a groove wheel and a fixing rod. For easy installation and transportation, the groove wheel is divided into several groove arc segments. It has the characteristics of saving water resources, high power generation efficiency and convenient disassembly and transportation.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a water turbine generator for a water channel, including a runner, a fixed rod, a grooved wheel, an automatic sluice gate and a fixed frame, wherein the automatic sluice gate is composed of an automatic device and a sluice gate.

[0005] The wheel has a rotating shaft and a fixing hole. The rotating shaft has a generator and a reverse speed increaser. The wheel has a fixing sleeve. One end of the fixing rod has a connector screw and the other end has a fixing post. The fixing post is connected to the fixing sleeve. The connector screw is connected to the fixing hole for fixation. The reverse speed increaser consists of an internal gear, planetary gears, a sun gear and a rotating shaft. The two ends of the rotating shaft have electric rings and fixing plates. The fixing plates consist of a vertical plate and a horizontal plate. The vertical plate is connected to the fixing frame and the horizontal plate is connected to the carbon brush. The carbon brush is slidably connected to the electric ring. The wires on the carbon brush are connected to the external power supply wires. In order for the wheel to rotate continuously, at least three water tanks must be immersed in the water of the channel. The support feet on the fixing frame are connected to the banks of the channel.

[0006] The grooved wheel is equipped with a left arc plate ring, a right arc plate ring, a bottom arc plate ring, partitions, a sluice gate, and an automatic device. The left arc plate ring is composed of multiple left arc plates, the right arc plate ring is composed of multiple right arc plates, and the bottom arc plate ring is composed of multiple bottom arc plates. Each of the left and right arc plates has a screw hole at one end and a folded edge at the other end, with screw holes on the folded edge. Each of the bottom arc plates has a screw hole at one end and a folded edge at the other end, with screw holes on the folded edge. The left arc plate ring has a long groove, and multiple partitions are placed between the left and right arc plates. The lower parts of the left and right arc plates and multiple partitions are connected to the bottom arc plate. The space between each partition is called a water tank. A left arc plate, a right arc plate, a bottom arc plate, and multiple partitions are combined to form a groove arc segment. The front part of the groove arc segment is connected to the rear part of another groove arc segment and fixed with screws. Connecting them into a circle forms the grooved wheel.

[0007] Each partition is equipped with a guide groove, each partition has a sluice gate in front of it, each sluice gate has screw holes, each sluice gate has side plates on both sides to increase the strength of the sluice gate, the sluice gate has wheels at the bottom, and each partition has an automatic device at the rear.

[0008] The automatic device consists of a hook, a slider, a groove, a sliding rod, a tension spring, a compression spring, and a roller. The slider has a protrusion, a hook, a movable hole, and a screw hole. The protrusion is located in the guide groove of the partition and is connected to the sluice gate. The screw is connected to the sluice gate through the screw hole on the slider. The hook is located on the partition and is connected to the hook by a tension spring. The groove has a sliding groove and a long hole. The groove is fixed to the rear of the partition. A sliding plate is located in the sliding groove and has a sliding hole. One end of the sliding rod has a movable shaft connected to the movable hole. The other end has a retaining ring and a clamping plate. The clamping plate first passes through the sliding hole on the sliding plate and the long hole on the groove before connecting to the roller. The roller is located in the long groove of the left arc plate ring. A compression spring is located on the sliding rod between the retaining ring and the slider.

[0009] A guide plate is installed on the bank of the canal. The guide plate has grooves and screw holes. Screws pass through the screw holes on the guide plate and are connected and fixed to the bank of the canal.

[0010] Each partition is equipped with a guide groove, a water gate is installed in front of each partition, and an automatic device is installed at the rear of each partition.

[0011] The long groove is located on either the left or right arc plate ring.

[0012] The beneficial effects of this invention are: in order to reduce the waste of water resources and improve power generation efficiency, the water turbine generator of this water channel is equipped with an automatic water gate on the partition plate. In order to increase wind resistance, the original two large circular plates are modified into a combination of a rotor, a groove wheel and a fixing rod. For easy installation and transportation, the groove wheel is divided into several groove arc segments. It has the characteristics of saving water resources, high power generation efficiency and convenient disassembly and transportation. Attached Figure Description

[0029] exist Figures 1-4 A water turbine generator for a water channel includes a runner 12, a fixed rod 2, a grooved wheel 1, an automatic sluice gate, and a fixed frame. The automatic sluice gate consists of an automatic device 22 and a sluice gate 5. A rotating shaft 13 is installed on the runner 12 and has a fixed hole drilled in it. A generator and a reverse speed increaser are installed on the rotating shaft 13. A fixed sleeve 11 is installed on the grooved wheel 1.

The carbon brush is slidably connected to the electric ring. The wires 14 on the carbon brush are connected to an external power supply wire. The support feet on the fixed frame are connected to both banks of the water channel.

[0030] A left arc plate ring, a right arc plate ring, a bottom arc plate ring, a partition plate 4, a sluice gate 5, and an automatic device 22 are installed on the grooved wheel 1. The left arc plate ring is composed of multiple left arc plates 10, the right arc plate ring is composed of multiple right arc plates 9, and the bottom arc plate ring is composed of multiple bottom arc plates 7. Screw holes 21 are drilled at one end of the left and right arc plates, and flanges 18 are pressed onto the other end of both the left and right arc plates. Screw holes are drilled on the flanges 18. Screw holes are drilled at one end of the bottom arc plate, and flanges 18 are pressed onto the other end of the bottom arc plate. The folded edges are drilled with screw holes. The left arc plate ring is milled with a long groove 17. Multiple partitions are installed between the left and right arc plates. The lower parts of the left arc plate, right arc plate and multiple partitions are connected to the bottom arc plate. The hollow between each partition is called a water tank. A left arc plate, a right arc plate, a bottom arc plate and multiple partitions are combined to form a groove arc segment 16. The folded edge at the front of each groove arc segment is connected to the rear of another groove arc segment and fixed with screws 6. When connected to form a circle, it is a groove wheel.

[0031] Each partition 4 is milled with a guide groove, each partition is equipped with a sluice gate 5, each sluice gate is drilled with screw holes 21, each sluice gate is pressed with side plates 24 on both sides, the side plates are used to increase the strength of the sluice gate, the sluice gate is equipped with wheels 23 at the bottom, and each partition is equipped with an automatic device 22 at the rear.

[0032] exist Figures 5-9 In the automatic device 22, there are hooks 35, sliders 26, grooves 38, slide rods 30, tension springs 34, compression springs 39, and rollers 19. The slider 26 has a protrusion 28 milled on it, a hook 27 installed on it, and a movable hole 29 and a screw hole 21 drilled on it. The protrusion 28 is installed in the guide groove 25 of the partition and connected to the sluice gate. The screw 6 is connected to the sluice gate through the screw hole on the slider. The hook is installed on the partition and is connected to the hook by a tension spring. The groove has a sliding groove 37 milled on it and a long hole 41. The groove is fixed to the rear of the partition. A slide plate 36 is installed in the sliding groove 37. A sliding hole 40 is drilled on the slide plate. One end of the slide rod has a movable shaft 31 machined on it and connected to the movable hole. The other end has a retaining ring 32 and a clamping plate 33 machined on it. The clamping plate is connected to the roller through the sliding hole on the slide plate and the long hole on the groove. The roller is installed in the long groove of the left arc plate ring. A compression spring 39 is installed on the slide rod between the retaining ring and the slider.

[0033] exist Figure 10 In the middle, a guide plate 42 is installed on the bank of the water channel. The guide plate has grooves 43 milled on it and screw holes 21 drilled in it. The screws pass through the screw holes on the guide plate and are connected and fixed to the bank of the water channel.

[0034] To describe the process of water damming and the related changes between rollers, tension springs, and compression springs associated with the dam, we will take four water tanks as an example. Three of the tanks are submerged in water. The four tanks are referred to as 3A, 3B, 3C, and 3D, respectively. The depth of the water channel is called the water level line 44 and is marked with a horizontal dashed line. The direction of the water flow 45 is marked with an arrow. The bottom surface of the water channel 46 is marked with a parallelogram dashed line. Originally, the groove 46 was located on the guide plate on the bank. For the sake of convenience, the groove is drawn with a dashed line on the left arc plate.

[0035] exist Figure 11As can be seen from the water level line 44, the water 45 flows through the first water tank 3A, the second water tank 3B, and the third water tank 3C. The water pushes the baffle 4 and the sluice gate 5 in the first water tank 3A, the sluice gate 5 in the second water tank 3B, and the sluice gate 5 in the third water tank 3C, causing the groove wheel 1 to rotate. The roller 19 of the first water tank 3A rolls to the left in the groove 43 of the dotted line, causing the tension spring 34 of the first water tank 3A to extend, so that the sluice gate of the first water tank 3A continues to extend and moves close to the bottom surface 46 of the water channel, blocking the leakage of the lower part of the sluice gate of the second water tank 3B. The intercepted leakage pushes the groove wheel to rotate, thus reducing the waste of water flow, until the sluice gate of the second water tank 3B is perpendicular to the bottom surface of the water channel, blocking all the water flow. At this time, all the water flow does work on the groove wheel. At the same time, under the action of the compression spring 39 in the second water tank 3B, the roller 19 in the second water tank 3B enters the groove 43 of the dotted line.

[0036] exist Figure 12 As can be seen from the water level line 44, the water flow 45 flows through the first water tank 3A, the second water tank 3B, and the third water tank 3C. The water flow 45 continues to push the sluice gate 5 in the first water tank 3A, the partition 4 in the second water tank 3B, the sluice gate 5, and the sluice gate 5 in the third water tank 3C, causing the groove wheel 1 to continue rotating to the left. The roller 19 in the second water tank 3B continues to roll to the left in the groove 43 of the dotted line, causing the sluice gate in the second water tank 3B to extend and move to the left close to the bottom surface 46 of the water channel, continuing to intercept the leakage water flowing out from the lower part of the sluice gate in the third water tank 3C. The intercepted leakage water pushes the groove wheel to rotate again, reducing the waste of water flow. Subsequently, the roller 19 in the first water tank 3A rolls out of the groove 43 of the dotted line, causing the tension spring 34 of the first water tank 3A to retract, driving the sluice gate 5 of the first water tank 3A to move upward and return to the front part of the partition 4 of the first water tank 3A.

[0037] exist Figure 13 As can be seen from water level line 44, water 45 flows through the first water tank 3A, the second water tank 3B, and the third water tank 3C. The water flows to the left as indicated by the arrow, continuing to push the partition 4 and sluice gate 5 of the second water tank 3B, and the partition 4 and sluice gate 5 of the third water tank 3C, causing the groove wheel 1 to continue rotating to the left. At the same time, the roller 19 of the second water tank 3B continues to roll to the left in the groove 43 of the dotted line, forcing the tension spring of the second water tank 3B to continue to extend, causing the sluice gate 5 of the second water tank 3B to continue to extend and move to the left at less than 90 degrees close to the bottom surface 46 of the water channel, continuing to intercept the water leakage at the bottom of the sluice gate 5 of the third water tank 3C. The intercepted leakage pushes the groove wheel to rotate, reducing the waste of water.

[0038] exist Figure 14As can be seen from water level line 44, water 45 flows through the sluice gate 5 of the second water tank 3B, the sluice gate 5 of the third water tank 3C, and the sluice gate 5 of the fourth water tank 3D. The water flows to the left as indicated by the arrow, continuing to push the sluice gate 5 of the second water tank 3B, the partition 4 and sluice gate 5 of the third water tank 3C, and the sluice gate 5 of the fourth water tank 3D, causing the groove wheel 1 to continue rotating to the left. Simultaneously, the roller 19 of the second water tank 3B continues to roll to the left in the groove 43 (dashed line), causing the tension spring of the second water tank 3B to extend, and the sluice gate 5 of the second water tank 3B to continue to adhere to... The water level 46 moves near the bottom of the channel, continuing to intercept the leakage from the lower part of the sluice gate 5 in the third water tank 3C. The intercepted leakage drives the wheel to rotate, reducing the waste of water flow, until the sluice gate 5 in the third water tank 3C is perpendicular to the bottom of the channel, preventing water from leaking out from the bottom. At this time, all the water flow does work on the wheel, and at the same time, under the action of the compression spring in the third water tank 3C, the roller 19 in the third water tank 3C enters the groove 43 shown in the dotted line. At this time, the sluice gate 5 in the third water tank 3C and the sluice gate 5 in the second water tank 3B return to the state shown in the diagram. Figure 1 The sluice gate 5 of the second water tank 3B is in the same state as the sluice gate 5 of the first water tank 3A.

[0039] As the water continues to push the sluice gates and baffles, the grooved wheel rotates continuously. At the same time, the rollers are intermittently pressed into or out of the grooves by the compression springs. With the help of the pullers, each sluice gate moves up or down in turn, blocking the leakage of water at the bottom of the sluice gate. The leakage then becomes the driving force for the rotation of the grooved wheel, preventing the water from being wasted.
