Description

Technical Field

[0001] This invention relates to the field of pipeline power generation technology, and specifically to a pipeline power generation device. Background Technology

[0002] With the rapid development of intelligent management technology, the application of sensors in pipeline management has achieved remarkable progress. For example, the monitoring of water pipes requires the installation of numerous sensors. However, many sensor installation points cannot provide a stable power supply. Therefore, it is necessary to install generators on the water pipes to generate electricity using the water pipe medium, thereby effectively powering the sensors.

[0003] However, after installing the sensor, the generator structure powering the sensor needs to bring the generator impeller into contact with the water flow in the water pipe. Therefore, it's necessary to drill holes or cut off sections of the water pipe. Thus, this type of generator is best installed during the pipe laying process. If installed on an already laid water pipe, water supply must be shut off. However, the necessity of shutting off and drilling holes in an intact water pipe to increase monitoring points is questionable. Nevertheless, installing sensors on the water pipe network does enhance monitoring. To meet the aforementioned need for installing sensors on already operational water pipes, we provide a pipeline power generation device. Summary of the Invention

[0006] A generator, wherein the output shaft of the generator is connected to the rotating shaft of the generator impeller;

[0007] The mounting mechanism is used to mount the generator impeller on the pipeline and to bring the rotating turbine in the generator impeller into contact with the medium in the pipeline. The mounting mechanism includes an mounting pipe that communicates with the pipeline.

[0010] In some embodiments, the inner diameter of the mounting tube is the same as the inner diameter of the pipe;

[0011] A section of the pipe is cut off to form an installation position with a length adapted to the installation pipe. The installation pipe is installed at the installation position in the pipe and is located in the installation cavity of the installation mechanism.

[0012] In some embodiments, the rotary turbine is installed inside the mounting tube, and the bottom of the rotating shaft is rotatably connected to the inner wall of the mounting tube, the top of the rotating shaft movably passes through the mounting tube and the fixed arc plate, and the rotating shaft is rotatably connected to the fixed arc plate or the top of the mounting tube via a bearing.

[0013] In some embodiments, the system further includes branch pipes, each of which penetrates the fixed arc plate and the inner wall of the mounting pipe, and the mounting pipe is provided with a water-blocking ring at the middle of the two ends of the branch pipe;

[0014] The rotating turbine is installed inside the branch pipe, and the rotating shaft is rotatably connected to the inner wall of the branch pipe, and the rotating shaft partially extends out of the branch pipe and is connected to the output shaft of the generator for transmission.

[0015] In some embodiments, the mounting tube is vertically fixedly mounted on the fixed arc plate, one end of the mounting tube is connected to the mounting cavity, and the other end of the mounting tube is fixedly mounted with a connecting flange; a generator cover plate is detachably connected to the connecting flange.

[0016] The corresponding installation pipe of the pipeline has an installation port;

[0017] The rotating shaft of the power generation impeller passes through the power generation cover plate, and the rotating shaft and the power generation cover plate are rotatably connected by bearings. The bottom of the rotating shaft carries a rotating turbine installed inside the pipe.

[0018] The generator is mounted on the generator cover plate and connected to the rotating shaft drive.

[0019] In some embodiments, a perforated sleeve is further included, the perforated sleeve being connected to an internal threaded connection, and a transmission rod being fixedly connected to the top of the perforated sleeve.

[0020] In some embodiments, a limiting block adapted to the inner diameter of the mounting pipe is installed on the shaft of the generator impeller via a one-way bearing, and the surface of the limiting block is provided with a thread adapted to the inner wall of the mounting pipe.

[0021] In some embodiments, the mounting tube and the fixed arc plate are connected by a closing mechanism;

[0022] The closing mechanism includes a mounting base located between the mounting tube and the fixed arc plate. The mounting base has a through hole communicating with the mounting tube and the mounting port. The inner wall of the through hole has a closing groove. One side of the closing groove is open.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. The installation of the fixed arc plate and the connecting arc plate of the present invention can effectively repair the leaking parts of the pipeline. That is, while facilitating pipeline maintenance, the device can effectively install sensors, generator impellers and generators to monitor the pipeline, without the need to stop the water supply specifically for installing sensors or generators.

[0028] 2. By setting up a water-blocking ring, the present invention allows the medium in the branch pipe to flow, while the rotating turbine is installed inside the branch pipe, which can avoid affecting the state of the medium in the installation pipe when the rotating turbine rotates, and effectively reduce interference with the sensor detection data located in the installation pipe.

[0029] 3. This invention allows for the repair of pipe ruptures by setting up fixed arc plates and connecting arc plates. The installation pipe, closing mechanism, and opening sleeve on the fixed arc plate enable opening operations on the pipe without interrupting the transport of the medium in the pipe, effectively reducing the waste caused by a large outflow of medium during opening. At the same time, the limiting block installed on the rotating shaft can seal the installation pipe when installing the rotating turbine, ensuring that there is no large outflow of medium during the entire installation process of the equipment.

[0043] Example 1:

[0044] Please see Figure 1 The pipeline power generation device of the present invention includes:

[0045] The power generation impeller 2 includes a rotating turbine 21 and a rotating shaft 22. The power generation impeller 2 is driven by the rotating turbine 21 to rotate the rotating shaft 22 through the impact of the medium flow in the pipe 1.

[0046] Generator 3, the output shaft of generator 3 is connected to the rotating shaft 22 of generator impeller 2;

[0047] Mounting mechanism 5 is used to mount the generator impeller 2 on the pipe 1 and to make the rotating turbine 21 in the generator impeller 2 contact the medium in the pipe 1. Mounting mechanism 5 includes an mounting pipe 6 that is connected to the pipe 1.

[0048] The installation mechanism 5 also includes a fixed arc plate 51 and a mating arc plate 52, and an installation cavity 53 adapted to the pipe 1 is formed between the fixed arc plate 51 and the mating arc plate 52.

[0049] The edges of the fixed arc plate 51 and the mating arc plate 52 are both fixedly connected with mounting ears 54. Each mounting ear 54 has a mounting hole. The mounting ears 54 of the fixed arc plate 51 and the mating arc plate 52 are connected by bolts passing through the mounting holes.

[0050] The inner diameter of the installation pipe 6 is the same as the inner diameter of the pipe 1;

[0051] A section is cut from the pipe 1 to form an installation position 4 with a length that matches the installation pipe 6. The installation pipe 6 is installed at the installation position 4 in the pipe 1 and is located in the installation cavity 53 of the installation mechanism 5.

[0052] The rotating turbine 21 is installed inside the mounting tube 6, and the bottom of the rotating shaft 22 is rotatably connected to the inner wall of the mounting tube 6. The top of the rotating shaft 22 moves through the mounting tube 6 and the fixed arc plate 51, and the rotating shaft 22 is rotatably connected to the fixed arc plate 51 or the top of the mounting tube 6 through a bearing.

[0053] Working principle:

[0054] In this embodiment, pipe 1 is a tap water pipe;

[0055] S1. When pipe 1 leaks and needs repair, the tap water supply needs to be shut off.

[0056] S2. Then, using tools such as a saw, cut off a section of the leaking part of pipe 1 to form an installation position 4 that is compatible with the installation pipe 6.

[0057] S3. Attach the fixed arc plate 51 in the installation mechanism 5 to the pipes 1 at both ends of the installation position 4, then place the installation pipe 6 into the installation position 4, and then attach the mating arc plate 52. Then, use bolts to pass through the mounting ears 54 on the fixed arc plate 51 and the mating arc plate 52, and use nuts to lock the bolts, so that the fixed arc plate 51 and the mating arc plate 52 are pressurized to form a seal.

[0058] The sensor can be installed inside or outside the mounting pipe 6 as needed. When the medium passes through the mounting pipe 6, it will flush the turbine to rotate. The rotation of the turbine 21 can generate electricity from the generator 3. The current generated by the generator 3 is processed by the rectifier and stored in the battery, and then the battery powers the sensor.

[0059] This method of installing sensors and power generation structures during water pipe maintenance not only increases monitoring of pipe 1 but also eliminates the need to shut off the water supply specifically for installing sensors or power generation devices. It effectively increases monitoring points within the already laid pipe 1, and the fixed arc plate 51 and connecting arc plate 52, in conjunction with the installation pipe 6, effectively facilitate the repair of leaks in pipe 1. In other words, this device not only facilitates pipe 1 maintenance but also effectively monitors pipe 1 by installing sensors, power generation impeller 2, and generator 3.

[0060] Example 2:

[0061] Please see Figure 2 As a variation of Embodiment 1, unlike Embodiment 1, it also includes a branch pipe 55, which penetrates the fixed arc plate 51 and the inner wall of the mounting pipe 6, and the mounting pipe 6 is provided with water-blocking rings 7 at both ends of the branch pipe 55.

[0062] The rotating turbine 21 is installed inside the branch pipe 55, and the rotating shaft 22 is rotatably connected to the inner wall of the branch pipe 55. The rotating shaft 22 extends partially out of the branch pipe 55 and is connected to the output shaft of the generator 3 for transmission.

[0063] In this embodiment, the water-blocking ring 7 allows the medium in the branch pipe 55 to flow, while the rotating turbine 21 is installed inside the branch pipe 55, which can prevent the rotating turbine 21 from affecting the state of the medium in the mounting pipe 6 when it rotates, effectively reducing interference with the sensor detection data located in the mounting pipe 6.

[0064] Example 3:

[0065] Please see Figures 3-8 The pipeline power generation device of the present invention includes: a power generation impeller 2, which includes a rotating turbine 21 and a rotating shaft 22. The power generation impeller 2 causes the rotating turbine 21 to drive the rotating shaft 22 to rotate by the impact of the medium flow in the pipeline 1.

[0066] Generator 3, the output shaft of generator 3 is connected to the rotating shaft 22 of generator impeller 2;

[0067] Mounting mechanism 5 is used to mount the generator impeller 2 on the pipe 1 and to make the rotating turbine 21 in the generator impeller 2 contact the medium in the pipe 1. Mounting mechanism 5 includes an mounting pipe 6 that is connected to the pipe 1.

[0068] The installation mechanism 5 also includes a fixed arc plate 51 and a mating arc plate 52, and an installation cavity 53 adapted to the pipe 1 is formed between the fixed arc plate 51 and the mating arc plate 52.

[0069] The edges of both the fixed arc plate 51 and the mating arc plate 52 are fixedly connected with mounting ears 54. Each mounting ear 54 has a mounting hole. The mounting ears 54 of the fixed arc plate 51 and the mating arc plate 52 are connected by bolts passing through the mounting holes.

[0070] The mounting pipe 6 is vertically fixed on the fixed arc plate 51. One end of the mounting pipe 6 is connected to the mounting cavity 53, and the other end of the mounting pipe 6 is fixedly installed with a connecting flange 8. A generator cover plate 10 is detachably connected to the connecting flange 8.

[0071] Pipe 1 has an installation port 14 corresponding to installation pipe 6;

[0072] The rotating shaft 22 of the generator impeller 2 passes through the generator cover plate 10, and the rotating shaft 22 and the generator cover plate 10 are rotatably connected by bearings. The bottom of the rotating shaft 22 carries a rotating turbine 21 installed inside the pipe 1. The generator 3 is installed on the generator cover plate 10 and is connected to the rotating shaft 22 for transmission. A limiting block 13 adapted to the inner diameter of the installation pipe 6 is installed on the rotating shaft 22 of the generator impeller 2 through a one-way bearing 15, and the surface of the limiting block 13 is provided with threads adapted to the inner wall of the installation pipe 6.

[0073] It also includes a perforated sleeve 11, which is connected to the internal thread of the installation, and a transmission rod 12 is fixedly connected to the top of the perforated sleeve 11.

[0074] The mounting tube 6 and the fixed arc plate 51 are connected by a closing mechanism 9. The closing mechanism 9 includes a mounting seat 91 located between the mounting tube 6 and the fixed arc plate 51. The mounting seat 91 has a through hole 92 that communicates with the mounting tube 6 and the mounting port 14. The inner wall of the through hole 92 has a closing groove 93. One side of the closing groove 93 is open. The inner wall of the closing groove 93 is connected to the closing plate 94 of the closing through hole 92 through the opening.

[0075] The closing mechanism 9 also includes a drive unit for inserting the closing plate 94 into the closing groove 93. The drive unit includes a fixed base 95, which is fixedly connected to the mounting base 91. The fixed base 95 has a storage cavity 96 for accommodating the closing plate 94, and the storage cavity 96 is connected to the closing groove 93 through an opening. The drive unit also includes a toothed groove 97 formed on the top of the closing plate 94, and a gear 98 meshing with the toothed groove 97. The gear 98 is rotatably connected to the fixed base 95, and the rotation shaft of the gear 98 extends out of the fixed base 95.

[0076] Working principle:

[0077] S1, please refer to Figure 3 When pipe 1 leaks and needs repair, the fixed arc plate 51 in the installation mechanism 5 is fastened to the leaking part of pipe 1, and then the connecting arc plate 52 is fastened. Then, the mounting ears 54 on the fixed arc plate 51 and the connecting arc plate 52 are passed through by bolts, and the bolts are locked by nuts, so that the fixed arc plate 51 and the connecting arc plate 52 are pressurized to form a seal, thereby completing the repair of the leak in pipe 1.

[0078] S2, please refer to Figure 6 Then, the drill is connected to the transmission rod 12 of the opening sleeve 11 by drilling tools such as electric drills. Then the electric drill is started. After the electric drill is started, it will rotate in the installation tube 6. When the opening sleeve 11 rotates downward in the installation tube 6, it will form an installation port 14 on the pipe 1.

[0079] Because the water supply to pipe 1 is not stopped, the pressure in pipe 1 will cause the pipe 1 block in the installation port 14 to be squeezed into the perforated sleeve 11; since the perforated sleeve 11 is threadedly connected to the inner wall of the installation pipe 6, the perforated sleeve 11 will be stably located in the installation pipe 6 through the self-locking property of the thread, and will isolate the medium.

[0080] S3. Then the electric drill rotates in the opposite direction, causing the opening sleeve 11 to rotate in the opposite direction and rise. When the end of the opening sleeve 11 is above the closing mechanism 9, the electric drill stops rotating and disconnects the electric drill from the transmission rod 12.

[0081] S4. Then connect the electric drill to the drive shaft 99 of the gear 98 and start it. When the drive shaft 99 is started by the electric drill, the gear 98 can drive the closing plate 94 to move from the storage cavity 96 in the fixed seat 95 to the closing groove 93 of the fixed seat 95, thereby isolating the medium.

[0082] S5. Connect the electric drill to the transmission rod 12 on the hole-opening sleeve 11, so that the hole-opening sleeve 11 rises again to disengage from the mounting tube 6.

[0083] S6, please refer to Figure 7 Insert the rotating turbine 21 in the generator impeller 2 into the mounting pipe 6, and make the limiting block 13 on the rotating shaft 22 connected by the one-way bearing 15 to the mounting pipe 6 in a preliminary threaded connection, thereby sealing the mounting pipe 6; it is necessary to ensure that the rotation direction of the limiting block 13 in the mounting pipe 6 is opposite to the rotation direction allowed by the one-way bearing 15.

[0084] S7. Then connect the electric drill to the drive shaft 99 of the gear 98 and start it in reverse so that the closing plate 94 located in the closing groove 93 moves to the storage cavity 96, thereby removing the obstruction to the mounting tube 6.

[0085] S8. Rotate the shaft 22 again in the opposite direction to the one-way bearing 15, thereby carrying the limit block 13 down in the mounting pipe 6, so that the rotating impeller extends into the pipe 1, and then the closing cover is connected to the connecting flange 8 by bolts.

[0086] S9. Connect the output shaft of the generator 3 on the closed cover plate to the rotating shaft 22 in the generator impeller 2, so as to generate electricity through the medium in the pipe 1.

[0087] In this technical solution, the fixed arc plate 51 and the connecting arc plate 52 can be used to repair the broken part of the pipeline 1. The installation pipe 6, the closing mechanism 9 and the opening sleeve 11 on the fixed arc plate 51 can be used to open the pipeline 1 without stopping the transport of the medium in the pipeline 1, which effectively reduces the waste caused by the large amount of medium flowing out during the opening. At the same time, the limiting block 13 installed on the rotating shaft 22 can seal the installation pipe 6 when installing the rotating turbine 21, so that there will be no large amount of medium flowing out and wasting during the entire installation process of the equipment.

[0088] Because the media in different pipes 1 are different, and the installation positions of the sensors used are different, if the sensor is installed outside the pipe, it can be installed directly and normally, and then powered by the electricity generated by the generator 3. If the sensor needs to be installed inside the pipe 1, it can be installed at the bottom of the limit block 13 and extended into the inside of the pipe 1, thereby effectively acquiring media data.

[0089] In Embodiments 1 to 3, both the fixed arc plate 51 and the mating arc plate 52 are provided with sealing gaskets on their inner walls. The sealing effect is achieved by the deformation of the sealing gaskets when they are squeezed together. The sealing gaskets can be rubber gaskets.

[0090] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
