Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pipeline valves, and particularly to a self-generating energy-saving pipeline switch device. Background Art

[0002] In many scenarios such as modern agriculture and garden maintenance, watering of plants is required. Currently, the two main watering methods are drip irrigation and sprinkler irrigation. Drip irrigation may cause salt accumulation, may limit root development, and is not suitable for irrigation during the freezing period. On the contrary, sprinkler irrigation has stronger adaptability.

[0003] In the initial stage of irrigation, people made multiple holes in a water pipe, inserted and fixed one end of the water pipe to a faucet. When the faucet was opened, water would be sprayed through the holes in the water pipe. With the further development of sprinkler irrigation technology, people began to set up sprinkler irrigation systems for sprinkler irrigation. By setting a ball valve in the underground pipeline of the sprinkler irrigation system, the ball valve was opened to allow the water in the underground pipeline to sprinkle plants.

[0004] With the development of technology, various types of pipeline valves have emerged on the market, from the initial mechanical ball valves to the later intelligent ball valves. For example, existing solenoid valves are mostly used in above-ground pipelines. Existing solenoid valves mostly use solar power supply and underground buried wire long-distance power supply. Such products have a short service life, high failure rate, and will also affect ground mechanical operations. For the intelligent ball valve installed in the underground pipeline, since its installation, whether it is used or not, the battery of the intelligent ball valve has been in a power-consuming state. When the battery power of the ball valve is exhausted, it still needs to be replaced to continue using. The workload of replacing the battery of the intelligent ball valve in the later stage is extremely large. Summary of the Invention

The following will make a detailed description of several specific embodiments of the present invention with reference to the drawings.

[0049] In the present invention, the self-powered energy-saving pipeline switch device can be a ball valve or a butterfly valve.

[0050] Optionally, the self-powered energy-saving pipeline switch device can also be other multi-angle switch valves.

[0051] First Embodiment

[0052] A self-powered energy-saving pipeline switch device mentioned in this embodiment, as Figure 1 shown, the self-powered energy-saving pipeline switch device includes a switch body 1, a control module 2, and a power generation module 3. The control module 2 is arranged on the switch body 1, and the power generation module 3 is arranged on the switch body 1. As Figures 1 to 3As shown in the figure, the switch body 1 includes a main pipe 11, a switch member 12 and a mounting seat 13. One end of the switch member 12 is spherical, and the spherical end of the switch member 12 has a through hole 121, and the other end of the switch member 12 has a clamping groove 122. The water flow cavity 111 of the main pipe 11 allows water flow to pass through. The middle part of the main pipe 11 has a receiving cavity 112 adapted to the spherical end of the switch member 12. One end of the main pipe 11 is its water inlet end 113, and the other end of the main pipe 11 is its water outlet end 114. The main pipe 11 has a mounting hole 115 communicating with the water flow cavity 111, and the mounting hole 115 is located at the water outlet end 114 of the main pipe 11, and the power generation module 3 is installed at the mounting hole 115. One end of the mounting seat 13 has a hemispherical receiving groove 131 for receiving a part of the spherical end of the switch member 12. The bottom of the receiving groove 131 has a first assembly hole 132.

[0053] The assembly process of the switch body 1 in this embodiment is as follows: As Figures 1 to 3 shown in the figure, the spherical end of the switch member 12 is arranged in the receiving cavity 112 of the main pipe 11, the mounting seat 13 is arranged in the receiving cavity 112, and the end of the switch member 12 provided with the clamping groove 122 passes through the receiving groove 131 and the first assembly hole 132 to the outside of the receiving groove 131, that is, the mounting seat 13 is installed on the switch member 12. A part of the spherical end of the switch member 12 is located in the receiving groove 131 of the mounting seat 13. The mounting seat 13 can make the switch member 12 more stably installed on the main pipe 11 and is also convenient for later maintenance and replacement. When the axis of the through hole 121 coincides with the axis of the main pipe 11, the switch member 12 opens the water flow cavity 111 of the main pipe 11. After the switch member 12 rotates 90°, when the axis of the through hole 121 is perpendicular to the axis of the main pipe 11, the switch member 12 closes the water flow cavity 111 of the main pipe 11.

[0054] In this embodiment, the switch body 1 can be further improved as follows:

[0055] Optionally, as Figure 1 shown in the figure, an indicating arrow 141 is provided on the outer pipe wall of the main pipe 11, and the direction of the indicating arrow 141 points from the water inlet end 113 of the main pipe 11 to the water outlet end 114 of the main pipe 11. For example, an indicating arrow 141 is sprayed on the outer pipe wall of the main pipe 11 with paint. By providing the indicating arrow 141 on the main pipe 11, the user can more conveniently understand the water flow direction of the self-powered energy-saving pipeline switch device.

[0056] Optionally, as Figure 3 shown in the figure, the bottom of the receiving groove 131 of the mounting seat 13 has a first mounting groove 133. A sealing ring is sleeved on the end of the switch member 12 provided with the clamping groove 122. When the mounting seat 13 is arranged on the switch member 12, the sealing ring is located in the first mounting groove 133. This can improve the sealing performance.

[0057] Optionally, as Figure 3 shown, a rotating shaft 123 is provided at one spherical end of the switch member 12, and a rotating groove 116 is provided at the bottom of the receiving cavity 112 of the main pipe 11. When the spherical end of the switch member 12 is disposed in the receiving cavity 112 of the main pipe 11, the rotating shaft 123 is located in the rotating groove 116. Such a setting can enable the switch member 12 to rotate more stably in the receiving cavity 112.

[0058] Optionally, as Figure 3 shown, two sealing cavities 117 are further provided in the main pipe 11, and the two sealing cavities 117 are respectively located at both ends of the receiving cavity 112. The switch body 1 further includes two plugging rings 15, and the two plugging rings 15 are respectively disposed in the two sealing cavities 117. A notch 134 is provided at the notch of the receiving groove 131 of the mounting seat 13. When the switch member 12 is disposed in the receiving cavity 112 of the main pipe 11, the mounting seat 13 is mounted on the switch member 12, and the two plugging rings 15 are respectively located in the two notches 134 of the mounting seat 13. At this time, the two plugging rings 15 seal the gap between the switch member 12 and the cavity wall of the receiving cavity 112 to prevent water from leaking through the gap. At the same time, the mounting seat 13 can fix the plugging rings 15 to further improve the sealing effect of the plugging rings 15 on the gap. On the basis of the above solution, a sealing groove 151 is provided on the plugging ring 15, and the sealing ring is sleeved in the sealing groove 151 of the plugging ring 15. Such a setting can further improve the sealing performance.

[0059] Optionally, as Figures 1 to 3 shown, flange plates 142 are provided at both the water inlet end 113 and the water outlet end 114 of the main pipe 11, and the flange plates 142 are provided with a plurality of holes. Such a setting facilitates the detachable connection of the self-powered energy-saving pipeline switch device of this embodiment to the underground pipeline. Preferably, external threads are provided at both the water inlet end 113 and the water outlet end 114 of the main pipe 11, and internal threads adapted to the external threads are provided in the central holes of the flange plates 142. By means of threaded connection, the flange plates 142 are detachably connected to the water inlet end 113 and the water outlet end 114 of the main pipe 11.

For example, the control unit 22 can adopt a control box. Optionally, screws are passed through the holes on the control unit 22, and the control unit 22 is fixed to the installation plate 202. The power supply member 21 and the control unit 22 are connected through an electric wire. The hydraulic valve 4 is arranged at the bottom of the assembly cavity 201. The bottom of the assembly cavity 201 has a third assembly hole 204. The driving end of the hydraulic valve 4 passes through the third assembly hole 204 and is inserted into the clamping groove 122 of the switch member 12. The driving end of the hydraulic valve 4 can be regarded as the driving end of the control module 2. The pilot valve 5 is arranged on the hydraulic valve 4. The plugging member 7 is arranged in the pilot valve 5. The driving member 6 is arranged on the pilot valve 5, and the driving end of the driving member 6 is detachably connected to one end of the plugging member 7. The driving member 6 and the control unit 22 are connected through an electric wire.

[0066] As Figure 9 , Figure 10As shown, the guiding valve 5 internally has a flow dividing portion, a first water outlet 51, a second water outlet 52 and an assembly port 53. The flow dividing portion is a T-shaped channel, and the flow dividing portion has three channel openings: a main water inlet 541, a first flow dividing opening 55, and a second flow dividing opening 56. The top of the guiding valve 5 has a main water inlet joint 54, and the main water inlet 541 is arranged inside the main water inlet interface. The first flow dividing opening 55 and the second flow dividing opening 56 are respectively arranged on both sides of the main water inlet 541. The first flow dividing opening 55 is communicated with the first water outlet 51 and is simultaneously communicated with a first flow dividing channel 57. The second flow dividing opening 56 is communicated with the second water outlet 52 and is simultaneously communicated with a second flow dividing channel 58. The guiding valve 5 is communicated with the water inlet channel 203 through a hose. Specifically, one end of the hose is inserted into the second connection joint 23, and the other end of the hose is inserted into the main water inlet joint 54. In this way, the main water inlet 541 of the guiding valve 5 can be communicated with the water inlet end 113 of the main pipe 11 through the water inlet channel 203. The assembly port 53 is located on one side of the guiding valve 5, and the assembly port 53 is located on the left side of the first flow dividing opening 55. The assembly port 53 is communicated with the first water outlet 51 and the first flow dividing opening 55.

[0067] As Figures 10 to 12 shown, the plugging member 7 includes a plugging shaft 71 and a connecting shaft 72. One end of the plugging shaft 71 is provided with a first plug 73, and the other end of the plugging shaft 71 is provided with a second plug 74. The first flow dividing opening 55 and the second flow dividing opening 56 have the same diameter, the first plug 73 and the second plug 74 have the same diameter, the diameter of the first plug 73 is larger than the diameter of the first flow dividing opening 55, and the diameter of the plugging shaft 71 is smaller than the diameter of the first flow dividing opening 55. One end of the connecting shaft 72 is connected to the first plug 73. Optionally, the plugging member 7 is made of a flexible material. Optionally, the second plug 74 is made of a flexible material. Preferably, the flexible material can be made of silica gel material or rubber material. When installing the plugging member 7 into the guiding valve 5, due to the material characteristics of the plugging member 7, the end of the plugging member 7 provided with the second plug 74 sequentially passes through the first flow dividing opening 55 and the second flow dividing opening 56. Finally, the plugging shaft 71 of the plugging member 7 is located inside the first flow dividing opening 55 and the second flow dividing opening 56, the first plug 73 is located on the left side of the first flow dividing opening 55, and the second plug 74 is located on the right side of the second flow dividing opening 56. The gaps between the plugging shaft 71 and the first flow dividing opening 55 and the second flow dividing opening 56 can allow water to flow through.

[0068] In this embodiment, the driving member 6 uses an electric push rod, and the telescopic end of the electric push rod can be regarded as the driving end of the driving member 6. The driving member 6 is arranged on one side of the guiding valve 5, and the driving end of the driving member 6 enters the assembly port 53. The driving end of the driving member 6 has a threaded hole, and one end of the connecting shaft 72 away from the first plug 73 has an external thread adapted to the threaded hole. The detachable connection between the plugging member 7 and the driving member 6 is realized through a threaded connection method.

[0069] Optionally, asFigure 11 As shown, a plurality of convex ridges 75 are further provided on the plugging shaft 71. The plurality of convex ridges 75 are uniformly arranged around the plugging shaft 71, and there is a gap 76 between two adjacent convex ridges 75. By providing a plurality of convex ridges 75 on the plugging shaft 71, the structural strength of the plugging member 7 can be further enhanced. At the same time, the gap 76 between the plurality of convex ridges 75 can allow water to flow through.

[0070] As Figure 9 , Figures 13 to 15 As shown, the hydraulic valve 4 includes a hydraulic housing 41 and a hydraulic component 42. The outer shape of the hydraulic housing 41 is C-shaped. There is a partition 411 inside the hydraulic housing 41. The partition 411 divides the housing cavity of the hydraulic housing 41 into two non-communicating chambers. One chamber is the first hydraulic chamber 412, and the other chamber is the second hydraulic chamber 413. The hydraulic housing 41 also has a first liquid passing hole 414 and a second liquid passing hole 415. The first liquid passing hole 414 communicates with the first hydraulic chamber 412, and the second liquid passing hole 415 communicates with the second hydraulic chamber 413. When the guiding valve 5 is arranged on the hydraulic housing 41, the first hydraulic chamber 412 communicates with the first diversion channel 57 of the guiding valve 5 through the first liquid passing hole 414, so that the first hydraulic chamber 412 can communicate with the first diversion port 55 and the first water outlet 51. The second hydraulic chamber 413 communicates with the second diversion channel 58 of the guiding valve 5 through the second liquid passing hole 415, so that the second hydraulic chamber 413 can communicate with the second diversion port 56 and the second water outlet 52. The shape of the hydraulic component 42 is C-shaped. Piston seals 43 are arranged at both ends of the hydraulic component 42. One end of the hydraulic component 42 is arranged in the first hydraulic chamber 412, and the piston seal 43 is located between the wall of the first hydraulic chamber 412 and one end of the hydraulic component 42. The piston seal 43 can assist the hydraulic component 42 to better seal the first hydraulic chamber 412. The other end of the hydraulic component 42 is arranged in the second hydraulic chamber 413, and the piston seal 43 is located between the wall of the second hydraulic chamber 413 and the other end of the hydraulic component 42. The piston seal 43 can assist the hydraulic component 42 to better seal the second hydraulic chamber 413. A clamping joint 44 is also arranged on the hydraulic component 42. One end of the clamping joint 44 is cylindrical, and the shape of the other end of the clamping joint 44 is adapted to the clamping groove 122 of the switch member 12. Specifically, the clamping joint 44 is located at the center of the C-shaped hydraulic component 42. The middle part of the hydraulic component 42 has a connecting part 45. The cylindrical end of the clamping joint 44 is connected to the hydraulic component 42 through the connecting part 45. The other end of the clamping joint 44 passes through the third assembly hole 204 and is inserted into the clamping groove 122 of the switch member 12. By arranging the clamping joint 44 in the clamping groove 122, the detachable connection between the hydraulic component 42 and the switch member 12 is realized. The clamping joint 44 of the hydraulic component 42 can be regarded as the driving end of the hydraulic valve 4.

[0071] Optionally, a sealing ring is provided between the pilot valve 5 and the hydraulic housing 41. The sealing ring is located at the connection between the first liquid passage hole 414 and the first shunt passage 57, and the sealing ring is located at the connection between the second liquid passage hole 415 and the second shunt passage 58, further improving the sealing performance.

[0072] Exemplary usage process of the self-powered energy-saving ball valve disclosed in this embodiment:

[0073] In this embodiment, the user electrically connects a mobile phone to the control unit 22 of the self-powered energy-saving pipeline switch device disclosed in this embodiment. Here, the connection method between the mobile phone and the control unit 22 is a prior art, and specifically, reference can be made to the connection method between a mobile phone and a shared bicycle.

[0074] As Figures 1 to 15 shown, the user uses the mobile phone to send a signal to the control unit 22 to open the water passage cavity 111. The control unit 22 receives the signal to open the water passage cavity 111. The control unit 22 controls the power supply member 21 to supply power to the driving member 6. The driving end of the driving member 6 contracts, and the plugging member 7 moves accordingly. The first plug 73 of the plugging member 7 plugs the first water outlet 51, and the second plug 74 plugs the second shunt port 56. At this time, the plugging member 7 is in the first position.

[0075] Water flows into the inlet end 113 of the main pipe 11 and is blocked by the switching member 12. Then the water sequentially flows through the first communication hole 161, the water inlet passage 203, the second communication hole 231, the hose, the main water inlet 541, the first shunt port 55, the first shunt passage 57, and the first liquid passage hole 414. Finally, the water enters the first hydraulic cavity 412. The water drives the hydraulic member 42 to rotate around the clamping joint 44. As the hydraulic member 42 rotates, the other end of the hydraulic member 42 squeezes the water in the second hydraulic cavity 413. The water in the second hydraulic cavity 413 sequentially flows through the second liquid passage hole 415 and the second shunt passage 58, and finally discharges from the second water outlet 52. The water in the first hydraulic cavity 412 gradually increases, and the water in the second hydraulic cavity 413 gradually decreases. Finally, when the axis of the through hole 121 coincides with the axis of the main pipe 11, the switching member 12 opens the water passage cavity 111 of the main pipe 11. Water flows from the inlet end 113 of the main pipe 11 to the outlet end 114 of the main pipe 11. When the water flows through the outlet end 114 of the main pipe 11, the water impacts the power end of the power generation module 3 to work and generate electricity, and the electricity generated by the power generation module 3 charges the power supply member 21.

[0076] The user uses the mobile phone to send a signal to the control unit 22 to close the water passage cavity 111. The control unit 22 receives the signal to close the water passage cavity 111. The control unit 22 controls the power supply member 21 to supply power to the driving member 6. The driving end of the driving member 6 extends, and the plugging member 7 moves accordingly. The first plug 73 of the plugging member 7 plugs the first diversion port 55, and the second plug 74 plugs the second water outlet 52. At this time, the plugging member 7 is in the second position. The water changes its flow path at the main water inlet 541 and successively flows through the second diversion port 56, the second diversion channel 58, the second liquid passing cavity, and finally the water enters the second hydraulic cavity 413. The water drives the hydraulic member 42 to rotate around the clamping joint 44. As the hydraulic member 42 rotates, one end of the hydraulic member 42 squeezes the water in the first hydraulic cavity 412. The water in the first hydraulic cavity 412 successively flows through the first liquid passing hole 414 and the first diversion channel 57, and finally is discharged from the first water outlet 51. The water in the second hydraulic cavity 413 gradually increases, and the water in the first hydraulic cavity 412 gradually decreases. Eventually, when the axis of the through hole 121 is perpendicular to the axis of the main pipe 11, the switching member 12 closes the water passage cavity 111 of the main pipe 11. The switching member 12 blocks the water, and the power generation module 3 stops working.

[0077] In this embodiment, the plugging member 7 in the second position is further introduced as follows:

[0078] Optionally, when the water enters the second diversion port 56 from the main water inlet 541, the water may flow to the first diversion port 55 and squeeze the first plug 73, causing the plugging member 7 to move to the left. However, during the entire process of closing the water passage cavity 111, the working response is very rapid. The water in the first hydraulic cavity 412 will be quickly discharged, and at the same time, it will squeeze the first plug 73 and cause the first plug 73 to re-plug the first diversion port 55. Therefore, the situation where the plugging member 7 gets stuck in the middle position due to pressure problems and both the first diversion port 55 and the second diversion port 56 are in the open state will not occur.

[0079] Optionally, the driving end of the driving member 6 extends to support the plugging member 7, so that the first plug 73 of the plugging member 7 plugs the first diversion port 55, and the second plug 74 plugs the second water outlet 52. The water passage cavity 111 can be smoothly closed without the risk of the plugging member 7 shifting.

[0080] Optionally, as Figure 11 、 Figure 12 shown, the structure of the plugging member 7 is further optimized. A sealing head 77 is also provided between the plugging shaft 71 and the first plug 73. When the plugging member 7 is in the second position and the first plug 73 plugs the first diversion port 55, the sealing head 77 is located in the first diversion port 55 and further plugs the first diversion port 55. Since the working response is very rapid during the entire process of closing the water passage cavity 111, there is no risk of the plugging member 7 shifting.

[0081] Compared with the prior art, the self - generating energy - saving pipeline switch device disclosed in this embodiment is applicable to various different scenarios such as farmland irrigation and garden irrigation. The self - generating energy - saving pipeline switch device is installed on an underground pipeline, and irrigation is carried out by controlling the opening of the water - passing cavity 111 to let water through or stopped by closing the water - passing cavity 111. After the self - generating energy - saving pipeline switch device of this embodiment is installed on the underground pipeline, there is no need to replace the power supply component 21 of the control module 2. When irrigation is carried out, the flowing water in the water - passing cavity 111 impacts the power - generating module 3 to generate electricity and charge the power supply component 21, so that the power of the power supply component 21 can always be maintained at a high - power state (in this embodiment, the high - power state means that the power supply is more than 70%). The entire product of the self - generating energy - saving pipeline switch device forms an internal circulation system, eliminating the need to replace the power supply component 21 and saving external power. Such a setting can extend the service life of the self - generating energy - saving pipeline switch device, and the maintenance process is simple.

[0082] Second Embodiment

[0083] The inventor found that impurities such as sand grains in the water may cause a risk of blockage at the connection between the water inlet channel 203 and the water inlet end 113, resulting in the inoperability of the self - generating energy - saving pipeline switch device of the first embodiment.

[0084] In view of this, this embodiment also proposes a self - generating energy - saving pipeline switch device. The second embodiment is a further improvement based on the first embodiment. The main improvement lies in that a filter element 81 is provided at the connection between the water inlet channel 203 and the water inlet end 113. The specific solution is as follows:

[0085] As Figure 7 shown, the control housing 20 has a filter groove 205, and the filter groove 205 is located at the channel opening of the water inlet channel 203 close to the first connection joint 16. Optionally, the filter element 81 can be a filter screen or a filter element. The filter element 81 is arranged in the filter groove 205, and a sealing ring is arranged inside the filter. The sealing ring is located at the notch of the filter groove 205. When the control housing 20 is arranged on the main pipe 11, the first connection joint 16 enters the filter groove 205, and the filter element 81 is located between the first connection hole 161 and the water inlet channel 203. The filter element 81 is used to filter impurities such as sand grains in the water. The sealing ring located at the notch of the filter groove 205 is used to seal the gap between the filter groove 205 and the first connection joint 16 to prevent water leakage.

[0086] Compared with the prior art, in this embodiment, by providing a filter element 81 at the connection between the water inlet channel 203 and the water inlet end 113 and using the filter element 81 to filter impurities such as sand grains in the water, the risk of blockage at the connection between the water inlet channel 203 and the water inlet end 113 is reduced.

[0087] Optionally, as Figure 7 shown, the control housing 20 has a first threaded hole 206 which communicates with the water inlet passage 203. The first threaded hole 206 is coaxially arranged with the water inlet passage 203 located within the mounting plate 202. During the later mass production of the control housing 20 by mold, by providing the first threaded hole 206 on the control housing 20, it is convenient for the forming of the control housing 20. The first bolt 24 has an external thread adapted to the first threaded hole 206. By means of threaded connection, the first bolt 24 is arranged within the first threaded hole 206, and the blocking of the first threaded hole 206 is achieved. This avoids water leakage and pressure relief in the water inlet passage 203.

[0088] Third Embodiment

[0089] The inventor found that when the irrigation cycle becomes longer, in the case where the power generation module 3 does not charge the power supply member 21, the power of the power supply member 21 is always in a power-consuming state.

[0090] This embodiment also proposes a self-generating energy-saving pipeline switch device. The third embodiment is a further improvement based on the first or second embodiment. The main improvement lies in that the control module 2 further includes a pressure switch 82, specifically as follows:

[0091] As Figure 6 、 Figure 7 、 Figure 9 shown, the pressure switch 82 is arranged within the assembly cavity 201 of the control housing 20, and the pressure switch 82 is arranged on the mounting plate 202. The sensing end of the pressure switch 82 is located within the water inlet passage 203. Specifically, a third communication joint 207 is provided on the mounting plate 202. The third communication joint 207 has a third communication hole 208. The water inlet passage 203 communicates with the outside through the third communication hole 208. The sensing end of the pressure switch 82 passes through the third communication hole 208 and enters the water inlet passage 203. The pressure switch 82 is electrically connected to the control unit 22 through an electric wire.

[0092] Compared with the prior art, in this embodiment, by adding a pressure switch 82 within the control module 2 and detecting the water pressure within the water inlet passage 203 through the pressure switch 82. When there is no water within the water inlet passage 203, the pressure switch 82 cannot detect the water pressure within the water inlet passage 203, and other components of the control module are in a power-off state. The self-generating energy-saving pipeline switch device of this embodiment can achieve an energy-saving effect. When there is water within the water inlet passage 203, the pressure switch 82 detects the water pressure within the water inlet passage 203, and the control unit 22 and the driving member 6 are in a working state. As irrigation progresses, the power generation module 3 charges the power supply member 21. Such a setting can not only keep the power supply member 21 in a high-power state for a long time, but also save energy.

[0093] Fourth Embodiment

[0094] This embodiment also proposes a self - generating energy - saving pipeline switch device. The fourth embodiment is a further improvement based on any one of the first to third embodiments. The main improvement lies in the structure of the driving member 6, which is specifically as follows:

[0095] Optionally, as Figure 6 shown, the driving member 6 adopts a linear motor. The telescopic end of the linear motor can be regarded as the driving end of the driving member 6.

When the driving housing 61 is arranged on the guiding valve 5, one end of the driving housing 61 enters the assembly port 53, and the water - passing hole 611 is aligned with the first water outlet 51 and is in communication with the first water outlet 51. The driving cavity includes a first driving sub - cavity 612 and a second driving sub - cavity 613. A fixing frame 66 is arranged in the first driving sub - cavity 612, and a sleeve 67 is arranged at the center of the fixing frame 66. The fixing frame 66 has two fixing layers 661 for accommodating driving coils 68, and the two fixing layers 661 are arranged in sequence along the length direction of the fixing frame 66. One driving coil 68 is arranged in one fixing layer 661 and is simultaneously sleeved on one end of the sleeve 67. The other driving coil 68 is arranged in the other fixing layer 661 and is simultaneously sleeved on the other end of the sleeve 67.

When the telescopic shaft 62 is arranged in the cavity of the sleeve 67, the connecting head 623 penetrates through the positioning hole 673 of the second positioning block 672 into the second driving sub-cavity 613. The connecting pipe 63 is arranged in the second driving sub-cavity 613, one end of the connecting pipe 63 is provided with a threaded hole, and one end of the connecting head 623 away from the telescopic shaft 62 is provided with an external thread adapted to the threaded hole.

One end of the connecting pipe 63 away from the connecting head 623 is provided with an assembly groove 631. The first magnet 64 is cylindrical, and the first magnet 64 is arranged in the assembly groove 631 of the connecting pipe 63. Internal threads are arranged at the notch of the assembly groove 631.

The annular magnet 65 and the first magnet 64 are arranged in a dislocation manner.

[0098] Optionally, the telescopic shaft 62 can be made of a magnetically conductive material or a permanent magnet.

[0099] The exemplary working process of the driving member 6 in this embodiment:

[0100] As Figures 16 to 18 shown, when the plugging member 7 is in the first position, the first positioning block 671 adsorbs the telescopic shaft 62, and the first positioning block 671 is located in the first positioning groove 621. When the plugging member 7 switches from the first position to the second position, the two driving coils 68 serve as the stationary part, and the telescopic shaft 62 serves as the moving part. The two coils are energized, and the telescopic shaft 62 moves to the right until the plugging member 7 is in the second position, and the second positioning block 672 adsorbs the telescopic shaft 62, and the second positioning block 672 is located in the second positioning groove 622. During the movement of the telescopic shaft 62, when the first magnet 64 is located in the annular magnet 65, the repulsive force between the two is utilized to accelerate the movement of the telescopic shaft 62.

[0101] In this embodiment, the telescopic shaft 62 is adsorbed by the first positioning block 671, and the sealing member 7 is located at the first position. Or the second positioning block 672 adsorbs the telescopic part, and the sealing member 7 is located at the second position. Even if the drive coil 68 is powered off, the sealing member 7 remains stably set at the first position or the second position. Such a setting can prevent the driving member 6 from being always powered on, further achieving the effect of energy saving.

[0102] Fifth Embodiment

[0103] This embodiment also proposes a self - generating energy - saving pipeline switch device. The fifth embodiment is a further improvement based on any one of the first to fourth embodiments. The main improvements are as follows:

[0104] As Figure 9 、 Figure 14 、 Figure 15 shown, the self - generating energy - saving pipeline switch device further includes a first position sensor 83, a second position sensor 84, a second magnet 85, and a third magnet 86. The first position sensor 83 is used to detect the in - place state of the second magnet 85, and the second position sensor 84 is used to detect the in - place state of the third magnet 86. The first position sensor 83 and the second position sensor 84 are respectively electrically connected to the control unit 22 through wires. Both ends of the hydraulic housing 41 have a second installation groove 416. Specifically, the first position sensor 83 is arranged in one second installation groove 416, and the first position sensor 83 is located at the orifice of the first hydraulic cavity 412. The second position sensor 84 is arranged in the other second installation groove 416, and the second position sensor 84 is located at the orifice of the second hydraulic cavity 413. Both ends of the hydraulic component 42 have a third installation groove 421. Specifically, the second magnet 85 is arranged in a third installation groove 421. When the sealing member 7 is in the first position, the second magnet 85 is located at the orifice of the first hydraulic cavity 412. The first position sensor 83 is used to detect the magnetic information of the second magnet 85. When the first position sensor 83 detects the magnetic information of the second magnet 85, it means that the second magnet 85 is in place, and at the same time, it also means that the water - passing cavity 111 is in an open state. The third magnet 86 is arranged in the other third installation groove 421. When the sealing member 7 is in the second position, the third magnet 86 is located at the orifice of the second hydraulic cavity 413. The second position sensor 84 is used to detect the magnetic information of the third magnet 86. When the second position sensor 84 detects the magnetic information of the third magnet 86, it means that the third magnet 86 is in place, and at the same time, it also means that the water - passing cavity 111 is in a closed state. When the first position sensor 83 fails to detect the in - place information of the second magnet 85, or the second position sensor 84 fails to detect the in - place information of the third magnet 86, it indicates that the hydraulic valve 4 has a fault, which is convenient for timely maintenance in the later stage.

One end of the water outlet joint 25 located in the assembly cavity 201 is respectively communicated with the first water outlet 51 and the second water outlet 52 of the guiding valve 5 through a tee 26. Such a setting can make the drainage of the guiding valve 5 concentrated on the same water outlet joint 25, avoiding the situation of water splashing when draining.

[0108] Optionally, not shown in the figure, on the basis of the above solution, one end of a hose is inserted into the end of the water outlet joint 25 located outside the assembly cavity 201, and the other end of the hose is communicated with the water outlet end 114 of the main pipe 11. Such a setting can make the discharged water be reused for irrigation.

[0109] Finally, it should be noted that those of ordinary skill in the art can understand that in order to enable readers to better understand the present invention, many technical details are proposed in the embodiments of the present invention. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions required to be protected by the claims of the present invention can be basically realized. Therefore, in practical applications, various changes can be made in form and details to the above embodiments without departing from the spirit and scope of the present invention.
