Description

Technical Field

[0001] The present invention relates to the technical field of wastewater utilization, and in particular to an underground wastewater power generation device and method. Background Art

[0002] Underground wastewater refers to wastewater generated in a series of activities such as production and life in mines or underground projects. It mainly includes wastewater generated during the mining process and sewage generated by mining equipment and working areas. Direct discharge of underground wastewater will not only cause environmental pollution, but also cannot be reused. Therefore, wastewater power generation equipment is usually installed underground to utilize the wastewater.

[0003] Existing wastewater power generation devices use a variety of methods to achieve wastewater power generation, such as a household wastewater power generation device with publication number CN111271209A, including a generator body, a power generation chamber is provided in the generator body, the left end of the power generation chamber is fixedly connected to the left end of a first spring, the right end of the first spring is fixedly connected to a power generation rack, the power generation rack meshes with a power generation gear, the right end of the rack is fixedly connected to a water baffle, the water baffle is slidably connected to the inner wall of the power generation chamber, the power generation gear is fixedly connected to a first transmission shaft, and the lower end of the first transmission shaft extends into the pulley chamber and is fixedly connected to the active pulley;

[0004] In actual use, the existing wastewater power generation device does not clean the impurities in the wastewater, so that when the wastewater drives the generator shaft to generate electricity, the impurities in the wastewater are easily attached to and entangled on the generator shaft, affecting the power generation efficiency. At the same time, the flow of wastewater is used to drive the generator shaft to rotate to generate electricity. The pressure exerted by the wastewater on the generator shaft is small, the speed of the generator shaft is slow, and the power generation efficiency is low. For example, the above-mentioned referenced prior art does not pre-treat the impurities in the wastewater when generating electricity from wastewater, so that the impurities are easy to cause interference during power generation. At the same time, the device only uses the natural flow of wastewater to drive the transmission shaft to rotate to enable the generator to generate electricity. This power generation method is largely limited by the flow pressure of the wastewater. When the flow pressure is small, the transmission shaft speed is slow, which makes the power generation effect of the generator poor and has certain limitations.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Example 1: Reference Figure 1-Figure 3 A downhole wastewater power generation device comprises a wastewater storage tank 1 for storing downhole wastewater. The wastewater storage tank 1 is used to store wastewater and realize automatic power generation by using wastewater.

[0050] The power generation device further comprises: a partition plate 7 arranged in the wastewater storage tank 1, the partition plate 7 plays a partitioning role, and is used to separate the water storage area inside the wastewater storage tank 1 from the power generation area, and a storage tank 6 for storing wastewater is arranged on the partition plate 7, and the storage tank 6 is used to realize automatic storage of wastewater;

[0051] The storage pressurizing unit is arranged in the storage tank 6, and is used to realize automatic storage of wastewater and remove impurities and purify the water quality in the wastewater during storage;

[0052] A generator 2 for generating electricity is arranged in the wastewater storage tank 1, and the generator 2 is started by the wastewater to realize automatic power generation;

[0053] The power generation unit is arranged in the wastewater storage tank 1. The power generation unit cooperates with the storage and pressurization unit. The driving shaft of the generator 2 is driven to rotate based on the impact of the wastewater in the storage and pressurization unit to achieve automatic power generation. At the same time, the rotation speed of the driving shaft of the generator 2 is adaptively increased based on the wastewater pressure to improve the power generation efficiency.

[0054] Example 2: Reference Figure 2-Figure 9 The difference between this embodiment and the first embodiment is that the storage pressurizing unit includes a pressurizing component and a cleaning component. A pressurizing plate 13 for pressurizing wastewater is slidably installed in the storage tank 6. The pressurizing component is used to store energy of wastewater and cooperate with the pressurizing plate 13 to discharge wastewater under pressure. The cleaning component is used to purify wastewater.

[0055] The pressurizing component includes a wastewater inlet pipe 3 fixedly installed between the wastewater storage tank 1 and the storage tank 6 for replenishing wastewater, a water screening box 10 for filtering impurities in the wastewater is fixedly installed in the storage tank 6, and the water screening box 10 is connected to the wastewater inlet pipe 3, and a plurality of screening holes 11 for discharging wastewater are opened in the water screening box 10;

[0056] The underground wastewater is poured into the water screening box 10 in the storage tank 6 through the wastewater inlet pipe 3, and is discharged through the multiple screening holes 11 on the water screening box 10. While the wastewater is being discharged, the impurities in it will be blocked by the screening holes 11 and will be accumulated in the water screening box 10, thereby realizing the automatic separation of impurities in the wastewater and the wastewater.

[0057] A sewage pipe is provided on the water screening box 10. After the waste water in the storage tank 6 is discharged, the impurities accumulated in the water screening box 10 are discharged through the sewage pipe, thereby completing the automatic discharge and collection of the impurities.

[0058] An energy storage mechanism is provided in the storage tank 6, and the energy storage mechanism includes two limit slide bars 18 fixedly installed in the storage tank 6, and the pressure plate 13 is slidably matched with the two limit slide bars 18, and a spring pressure rod 19 for the pressure plate 13 to move downward and reset is fixedly installed between the two limit slide bars 18 and the pressure plate 13;

[0059] After the wastewater enters the storage tank 6, it will accumulate at the bottom of the pressure plate 13 therein. As the amount of wastewater at the bottom of the pressure plate 13 gradually increases, the pressure plate 13 will be gradually pushed to slide upward in the storage tank 6. The upward movement of the pressure plate 13 will compress the spring pressure rod 19 thereon, thereby realizing automatic energy storage of the wastewater pressure.

[0060] In a further embodiment, a linkage rod is rotatably mounted on the water screening box 10, and a threaded rod 15 is fixedly mounted on the linkage rod, a limit nut 12 is fixedly mounted on the pressure plate 13, and the limit nut 12 is slidably matched with the threaded rod 15;

[0061] When the pressure plate 13 moves up and down, it will drive the limit nut 12 thereon to move up and down synchronously. Since the limit nut 12 is threadedly matched with the threaded rod 15, and the limit nut 12 can only move up and down and cannot rotate, when the limit nut 12 moves up and down, it will drive the threaded rod 15 to rotate forward and reverse, and then drive the linkage rod to rotate synchronously, so that when the pressure plate 13 moves up and down, it can synchronously drive the linkage rod to rotate forward and reverse.

[0062] The cleaning assembly includes a storage box 14 fixedly mounted on the upper part of the storage tank 6, and the storage box 14 is filled with a purification liquid for purifying wastewater, a feeding mechanism is installed between the storage box 14 and the pressure plate 13, and a plurality of stirring impellers 17 for stirring the wastewater are fixedly mounted on the linkage rod, and the plurality of stirring impellers 17 are all located at the lower part of the pressure plate 13;

[0063] When the linkage rod rotates, the plurality of stirring impellers 17 thereon will be driven to rotate. When the stirring impellers 17 rotate, the wastewater under the pressure plate 13 will be rotated and stirred, thereby achieving automatic stirring of the wastewater.

[0064] The feeding mechanism includes an upper pressing plate 20 slidably mounted in the material storage box 14, and a trigger pin 22 is slidably mounted between the upper pressing plate 20 and the material storage box 14, a trigger rod 21 matched with the trigger pin 22 is fixedly mounted on the pressure plate 13, and a telescopic injection pipe 16 for discharging the purified liquid is fixedly connected between the material storage box 14 and the pressure plate 13;

[0065] When the pressure plate 13 moves upward, it will synchronously drive the trigger rod 21 thereon to move upward. When the trigger rod 21 moves upward to squeeze the trigger pin 22, when the pressure plate 13 continues to move upward, the trigger pin 22 will be driven upward by the trigger rod 21. The upward movement of the trigger pin 22 will drive the upper pressure plate 20 to move upward in the storage box 14. When the upper pressure plate 20 moves upward, it will squeeze the purified liquid in the storage box 14 and automatically inject it into the lower part of the pressure plate 13 through the telescopic injection tube 16. The injection amount of the purified liquid can be automatically controlled according to the upward movement distance of the pressure plate 13, so as to realize the quantitative injection of the purified liquid.

[0066] The purified liquid in the telescopic injection tube 16 will be injected into the wastewater at the bottom of the pressure plate 13, so that the wastewater can be automatically purified. During the purification process, the wastewater and the purified liquid are stirred by the cooperation of the stirring impeller 17, so that the wastewater and the purified liquid are mixed more evenly, thereby improving the purification effect of the wastewater.

[0067] The storage box 14 is fixedly connected with a feeding pipe 4 for automatically replenishing the purified liquid. The feeding pipe 4 is used to automatically replenish the purified liquid into the storage box 14. When the pressure plate 13 moves downward, the purified liquid can be automatically replenished into the storage box 14 through the feeding pipe 4 to facilitate the re-purification of the wastewater.

[0068] Example 3: Reference Figure 1-Figure 4 as well as Figure 10-Figure 14 The technical solution of this embodiment is different from that of the second embodiment in that the power generation unit includes a driving component and a speed increasing component, wherein an impact impeller 27 is arranged in the driving component, and the impact impeller 27 rotates under the drive of the wastewater and drives the generator 2 to start with the cooperation of the speed increasing component to realize automatic power generation.

[0069] The driving assembly includes a water pressure pipe 9 fixedly connected to the lower part of the storage tank 6 for discharging sewage, and the lower part of the water pressure pipe 9 is fixedly connected to a driving box 8;

[0070] When the wastewater in the storage tank 6 is stored to a certain amount, the water pressure pipe 9 can be opened, and the wastewater in the storage tank 6 will be automatically injected into the drive box 8 through the water pressure pipe 9 to complete the wastewater extraction;

[0071] While the wastewater is being discharged, the two spring pressure rods 19 will automatically extend and reset to complete the release of stored energy, thereby pushing the pressure plate 13 downward at a faster speed, thereby accelerating the speed of wastewater discharge, realizing automatic pressurization of wastewater, and increasing the flow rate of wastewater under the cooperation of the gravity of wastewater;

[0072] The sewage pressure pipe 9 is composed of multiple sections of pipe bodies with gradually decreasing pipe diameters, and the flow pressure of the wastewater is further increased by the gradually decreasing pipe diameters, thereby further increasing the downstream velocity of the wastewater.

[0073] In a further embodiment, a linkage mechanism is installed in the drive box 8, and the linkage mechanism includes a drive rod 28 rotatably installed in the drive box 8, and an impact impeller 27 that cooperates with the wastewater in the sewer pressure pipe 9 is fixedly installed on the drive rod 28. When the wastewater enters the drive box 8, it will impact the multiple impact impellers 27 in the drive box 8, thereby driving the multiple impact impellers 27 to rotate, and then driving the drive rod 28 to rotate automatically.

[0074] A driving roller 26 is fixedly mounted on the driving shaft of the generator 2, and an acceleration structure is installed between the driving roller 26 and the driving rod 28, the acceleration structure includes a driven ring frame 29 fixedly mounted on the driving rod 28, and the driven ring frame 29 is located outside the driving box 8, an outer gear ring 24 is fixedly mounted on the driven ring frame 29, a plurality of internal gears 30 are rotatably mounted in the wastewater storage tank 1 through a plurality of support frames 32, and the outer sides of the plurality of internal gears 30 are all meshed with the outer gear ring 24, a driving gear 31 is fixedly mounted on the driving roller 26, and the driving gear 31 is meshed with the inner sides of the plurality of internal gears 30;

[0075] When the driving rod 28 rotates, it drives the driven ring frame 29 outside the driving box 8 to rotate. When the driven ring frame 29 rotates, it drives the outer gear ring 24 thereon to rotate. The rotation of the outer gear ring 24 drives the multiple internal gears 30 meshing therewith to rotate. The rotation of the multiple internal gears 30 drives the driving gear 31 to rotate, and then drives the driving roller 26 to rotate. The rotation of the driving roller 26 drives the driving shaft of the generator 2 to rotate, and the generator 2 can be driven to start and realize automatic power generation.

[0076] The number of teeth of the outer gear ring 24 is much larger than the number of teeth of the inner gear 30, so that when the outer gear ring 24 rotates one circle, the inner gear 30 will rotate multiple circles, that is, the rotation speed of the inner gear 30 is much larger than the rotation speed of the outer gear ring 24, and the number of teeth of multiple inner gears 30 is similar to that of the driving gear 31, that is, the difference between the rotation speed of multiple inner gears 30 and the rotation speed of the driving gear 31 is different, that is, the rotation speed of the driving gear 31 is much larger than the rotation speed of the outer gear ring 24, and the rotation speed of the outer gear ring 24 is the same as the rotation speed of the driving rod 28, which means that the rotation speed of the driving roller 26 is much larger than the rotation speed of the driving rod 28, that is, the speed increase of the driving roller 26 is achieved, and then the automatic speed increase of the driving shaft of the generator 2 is achieved, thereby effectively improving the power generation efficiency of the generator 2.

[0077] The speed increasing assembly includes a water distribution pipe 33 fixedly connected to the water pressure pipe 9, a speed increasing plate 25 fixedly connected to the water distribution pipe 33, and the speed increasing plate 25 is rotatably connected to the driving roller 26, an electric control locking wheel 34 is provided on the driving roller 26, and a speed increasing impact wheel 35 matched with the water distribution pipe 33 is fixedly installed on the electric control locking wheel 34;

[0078] If the wastewater is reduced and the water pressure is insufficient, the rotation speed of the driving rod 28 decreases, so that the rotation speed of the driving roller 26 moves down synchronously. At this time, the water distribution pipe 33 can be opened to allow the wastewater in the sewer pressure pipe 9 to be introduced into the water distribution pipe 33. At the same time, the electrically controlled locking wheel 34 is started to lock it with the driving roller 26. The wastewater in the water distribution pipe 33 will enter the speed increasing disk 25 and impact the speed increasing impact wheel 35 therein after entering, thereby driving the speed increasing impact wheel 35 to rotate, thereby driving the driving roller 26 to rotate, thereby realizing the secondary speed increase of the driving roller 26, thereby increasing the rotation speed of the driving shaft of the generator 2 and improving the power generation efficiency of the generator 2.

[0079] The electric-controlled locking wheel 34 is a part that can be automatically locked in the prior art. The basic principle applied to the present invention is: when the electric-controlled locking wheel 34 is not locked, it is connected to the driving roller 26 for rotation. At this time, the rotation of the driving roller 26 will not drive the electric-controlled locking wheel 34 to rotate. When the electric-controlled locking wheel 34 is started, its internal clamping rod will automatically move and lock into the driving roller 26, and automatically lock with the driving roller 26. At this time, the rotation of the driving roller 26 will drive the electric-controlled locking wheel 34 to move. Conversely, the rotation of the electric-controlled locking wheel 34 will synchronously drive the driving roller 26 to rotate.

[0080] This part is the prior art and will not be described in detail here.

[0081] A drainage box 23 is fixedly installed in the wastewater storage tank 1, and a wastewater drainage pipe 5 for discharging sewage is arranged on the drainage box 23, a water guide pipe is fixedly connected between the drainage box 23 and the driving box 8, and a downpipe 36 for drainage is fixedly connected between the speed increasing plate 25 and the drainage box 23;

[0082] After the impact is completed, the wastewater in the drive box 8 will be injected into the drainage box 23 through the water pipe. After the impact is completed, the wastewater in the speed increaser 25 will be injected into the drainage box 23 through the downpipe 36, and finally the wastewater will be automatically discharged through the wastewater drain pipe 5, thereby realizing the automatic discharge and collection of wastewater.

[0083] The specific working principle of this underground power generation device is:

[0084] The underground wastewater is poured into the water screening box 10 in the storage tank 6 through the wastewater inlet pipe 3, and is discharged through the multiple screening holes 11 on the water screening box 10. When the wastewater is discharged, the impurities in it will be blocked by the screening holes 11 and will be accumulated in the water screening box 10, so that the impurities in the wastewater are automatically separated from the wastewater;

[0085] After the wastewater enters the storage tank 6, it will accumulate at the bottom of the pressure plate 13 therein. As the amount of wastewater at the bottom of the pressure plate 13 gradually increases, the pressure plate 13 will be gradually pushed to slide upward in the storage tank 6. The upward movement of the pressure plate 13 will compress the spring pressure rod 19 thereon, thereby realizing automatic energy storage of the wastewater pressure.

[0086] When the pressure plate 13 moves upward, it will synchronously drive the trigger rod 21 thereon to move upward. When the trigger rod 21 moves upward to squeeze the trigger pin 22, when the pressure plate 13 continues to move upward, the trigger pin 22 will be driven upward by the trigger rod 21. The upward movement of the trigger pin 22 will drive the upper pressure plate 20 to move upward in the storage box 14. When the upper pressure plate 20 moves upward, it will squeeze the purified liquid in the storage box 14 and automatically inject it into the lower part of the pressure plate 13 through the telescopic injection tube 16. The injection amount of the purified liquid can be automatically controlled according to the upward movement distance of the pressure plate 13, so as to realize the quantitative injection of the purified liquid.

[0087] When the pressure plate 13 moves up and down, it will drive the limit nut 12 thereon to move up and down synchronously, thereby driving the threaded rod 15 and the linkage rod to rotate synchronously in the forward and reverse directions. When the linkage rod rotates, it will drive the multiple stirring impellers 17 thereon to rotate, and the purified liquid in the telescopic injection tube 16 will be injected into the wastewater at the bottom of the pressure plate 13, so that the wastewater can be automatically purified. In the purification process, the wastewater and the purified liquid are stirred through the cooperation of the stirring impeller 17, so that the wastewater and the purified liquid are mixed more evenly, thereby improving the purification effect of the wastewater.

[0088] When the wastewater in the storage tank 6 is stored to a certain amount, the water pressure pipe 9 can be opened, and the wastewater in the storage tank 6 will be automatically injected into the drive box 8 through the water pressure pipe 9 to complete the wastewater extraction;

[0089] While the wastewater is being discharged, the two spring pressure rods 19 will automatically extend and reset to complete the release of stored energy, thereby pushing the pressure plate 13 downward at a faster speed, thereby accelerating the speed of wastewater discharge, realizing automatic pressurization of wastewater, and increasing the flow rate of wastewater under the cooperation of the gravity of wastewater;

[0090] When the driving rod 28 rotates, it drives the driven ring frame 29 outside the driving box 8 to rotate. When the driven ring frame 29 rotates, it drives the outer gear ring 24 thereon to rotate. The rotation of the outer gear ring 24 drives the multiple internal gears 30 meshing therewith to rotate. The rotation of the multiple internal gears 30 drives the driving gear 31 to rotate, and then drives the driving roller 26 to rotate. The rotation of the driving roller 26 drives the driving shaft of the generator 2 to rotate, and the generator 2 can be driven to start and realize automatic power generation.

[0091] If the wastewater is reduced and the water pressure is insufficient, the rotation speed of the driving rod 28 decreases, so that the rotation speed of the driving roller 26 moves down synchronously. At this time, the water distribution pipe 33 can be opened to allow the wastewater in the sewer pressure pipe 9 to be introduced into the water distribution pipe 33. At the same time, the electrically controlled locking wheel 34 is started to lock it with the driving roller 26. The wastewater in the water distribution pipe 33 will enter the speed increasing disk 25 and impact the speed increasing impact wheel 35 therein after entering, thereby driving the speed increasing impact wheel 35 to rotate, thereby driving the driving roller 26 to rotate, thereby realizing the secondary speed increase of the driving roller 26, thereby increasing the rotation speed of the driving shaft of the generator 2 and improving the power generation efficiency of the generator 2.

[0092] The embodiment of the present invention further provides a method for generating electricity from underground wastewater, which is used in the above-mentioned underground wastewater generating device, and comprises the following steps:

[0093] S1, underground wastewater is introduced into the storage tank 6 in the wastewater storage tank 1 for storage, and during the storage process, the pressure plate 13 is driven to move upward to realize pressurized energy storage;

[0094] S2, when the pressure plate 13 moves upward, the cleaning component is driven to start filtering, screening and purifying the wastewater;

[0095] S3, the pressurizing component drives the pressurizing plate 13 to move downward to press the wastewater in the storage tank 6 into the power generation unit, and the driving component cooperates to drive the driving shaft of the generator 2 to rotate, thereby realizing automatic power generation;

[0096] S4. During the power generation process, the speed increasing component is started to increase the speed of the driving shaft of the generator 2 to improve the power generation efficiency.

[0097] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
