[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] This invention discloses a solar-powered anti-theft smart observation well.
[0024] Example 1 Reference Figures 1-13This invention provides a solar-powered anti-theft smart observation well, comprising an electromagnetic valve body 1 and an ABS electric valve protection well 2. A well shaft end 21 is detachably mounted on the ABS electric valve protection well 2 via a flange. The well shaft end 21 is equipped with a protective cover 3 for anti-theft purposes on the electromagnetic valve body 1. A light-transmitting lens 4 is fixedly mounted on the sun-facing end of the protective cover 3. A solar concentrating mechanism 5 for concentrating solar energy is located on the protective cover 3 and below the light-transmitting lens 4. The protective cover 3 also has an anti-theft mechanism 6 for limiting its rotation. The protective cover 3 is also fixedly mounted with a battery 7 and a controller body 8, and the battery 7 and the controller body 8 are electrically connected to the solenoid valve body 1 through a control power line 9. The focusing mechanism 5 includes a focusing plate 51, which is fixedly mounted on the protective cover 3 and corresponds to the light-transmitting lens 4. The focusing plate 51 is transparent, and the inner wall of the focusing plate 51 is provided with focusing spherical protrusions 511 arranged in a ring along the light-transmitting lens 4. The focusing spherical protrusions 511 are raised hemispherical shapes. A solar panel 53 is fixedly mounted on the protective cover 3 below the focusing plate 51. The solar panel 53 is provided with a solar panel 53. The antenna 54 is electrically connected to the controller body 8. The ABS electric valve protection well 2 is made of ABS material, which has the characteristics of corrosion resistance, aging resistance, and high strength. It can effectively adapt to the harsh outdoor and underground humid and dusty use environment. The protective cover plate 3 serves as the closed protective structure of the well end 21. The light-transmitting lens 4 is made of high light transmittance tempered glass, which has the performance of impact resistance and scratch resistance, and can ensure the efficient transmission of natural light. The transparent light-concentrating plate 51 is precisely aligned with the light-transmitting lens 4 to ensure that natural light can enter the interior of the light-concentrating plate 51 without obstruction. The hemispherical light-concentrating spheres 511 arranged in a ring on its inner wall are... Designed based on the principle of convex lens focusing, it can converge natural light incident from different angles, so that the light is concentrated onto the solar panel 53 below, significantly improving the photoelectric conversion efficiency. After the solar panel 53 completes the photoelectric conversion, it stores the electrical energy in the battery 7. The battery 7 provides a continuous and stable power supply to the controller body 8 and the solenoid valve body 1. The controller body 8 realizes intelligent on / off control of the solenoid valve body 1 through the control power line 9. The antenna 54 is electrically connected to the controller body 8, which can realize remote signal transmission of the controller body 8, making it convenient for staff to remotely monitor and operate the solenoid valve body 1.
[0025] A sealing ring groove 512 is also provided on the outer wall of the light-concentrating plate 51. A sealing ring 52 that matches the sealing ring groove 512 is fitted on the light-concentrating plate 51. The sealing ring 52 is located between the inner wall of the protective cover plate 3 and the light-concentrating plate 51. The sealing ring groove 512 is an annular groove structure on the outer wall of the light-concentrating plate 51. When the light-concentrating plate 51 is installed on the protective cover plate 3, the sealing ring 52 is tightly squeezed between the inner wall of the protective cover plate 3 and the outer wall of the light-concentrating plate 51, forming an annular sealing structure, which effectively blocks external dust and moisture from entering through the gap between the light-concentrating plate 51 and the protective cover plate 3.
[0026] A pivot pin 31 is fixedly installed on the protective cover plate 3, and the protective cover plate 3 is rotatably connected to the well end 21 through the pivot pin 31. The inner side of the protective cover plate 3 is provided with concentrically distributed inner ring parts 32. The end of the well end 21 near the protective cover plate 3 is provided with a stepped groove 211. The stepped groove 211 is distributed along the inner contour of the protective cover plate 3. The protective cover plate 3 can rotate flexibly around the pivot pin 31 to realize the opening and closing of the protective cover plate 3. The inner ring part 32 is adapted to the end of the well end 21, and can achieve precise alignment with the well end 21 when the protective cover plate 3 is closed. The stepped groove 211 is a stepped annular groove structure, which can form a precise locking fit with the locking tongue part 631 of the subsequent anti-theft mechanism 6, providing a basis for the limiting and locking of the anti-theft mechanism 6.
[0027] An inner ring partition 321 is fixedly installed on the inner ring 32. The solar panel 53, the battery 7, and the controller body 8 are respectively fixedly installed on the inner ring partition 321 by screws. The inner ring partition 321 provides a stable mounting support surface for the solar panel 53, the battery 7, and the controller body 8, ensuring that they operate independently and do not interfere with each other. It also facilitates the exposure of the battery 7 and the controller body 8 for maintenance when the protective cover 3 is opened.
[0028] The anti-theft mechanism 6 includes a lock frame 61 fixed to the protective cover plate 3 by screws. The lock frame 61 has an integrally formed spring retainer ring 611, and a return spring 62 is fitted onto the spring retainer ring 611. An anti-theft lock 63 is rotatably connected to the lock frame 61. The two ends of the return spring 62 abut against the spring retainer ring 611 and the anti-theft lock 63, respectively. The bottom end of the anti-theft lock 63 has a latch 631 that matches the stepped groove 211. A lock permanent magnet 632 is also installed on the side of the anti-theft lock 63 away from the return spring 62 by screws. The lock frame 61 can be installed on the protective cover plate 3 by screws and moves synchronously with the protective cover plate 3. 611 provides axial limiting for the return spring 62 to prevent it from shifting or falling off. The return spring 62 is a hard spring that has undergone corrosion-resistant and moisture-proof treatment. Under slight compression, it can provide continuous elastic force to the anti-theft lock 63 through the contact between its two ends and the spring retaining ring 611 and the anti-theft lock 63. This drives the anti-theft lock 63 to rotate around the lock frame 61, so that the locking tongue 631 at the bottom of the anti-theft lock 63 is engaged with the stepped groove 211 of the well shaft end 21. This achieves the limiting and locking of the protective cover 3 and the well shaft end 21, preventing the protective cover 3 from being illegally opened. The lock permanent magnet 632 is fixed to the anti-theft lock 63 with screws, which is a firm connection and easy to replace.
[0029] The anti-theft mechanism 6 also includes a latch body 64 fixedly installed on the protective cover plate 3 and corresponding to the lock frame 61. A key pin 65 for limiting the rotation of the anti-theft lock 63 is slidably connected in the latch body 64. The latch body 64 provides guide support for the sliding and rotation of the key pin 65. The key pin 65 is the unlocking control component of the anti-theft mechanism 6. Its sliding connection design with the latch body 64 allows the key pin 65 to slide back and forth along the axial direction of the latch body 64, and at the same time rotate around its own axis. Through the combined action of sliding and rotation, the rotation of the anti-theft lock 63 is limited and unlocked. Only by operating the dedicated key pin 65 can the anti-theft lock 63 be released from the protective cover plate 3.
[0030] The latch body 64 has through-hole guide lock holes 641. A limiting groove 641 corresponding to the guide lock holes 641 is fixedly installed at the end of the latch body 64 near the anti-theft lock 63. A guide groove 642 for guiding the rotation of the key pin 65 is also provided at the end of the latch body 64 near the anti-theft lock 63. The guide groove 642 has an opening communicating with the guide lock holes 641. The guide lock holes 641 provide an axial sliding guide channel for the key pin 65, allowing the key pin 65 to slide along the lock within the guide lock holes 641. The axial sliding of the main body 64 and the limiting slot 6411 can limit the maximum axial movement distance of the key pin 65 in the guide lock hole 641, providing guidance for the next step of rotation unlocking. The guide groove 642 is a special arc-shaped curved groove structure. Its opening position is adapted to the rotation trajectory of the anti-theft lock 63, and its opening provides a channel for the rod of the key pin 65 to enter the guide groove 642, so that the key pin 65 can rotate along the guide groove 642 after axial sliding. The unlocking control of the anti-theft lock 63 is realized by the rotation action.
[0031] The key pin 65, located at one end of the latch body 64, has an anti-disengagement protrusion 651 that matches the guide lock hole 641. The key pin 65 slides axially along the latch body 64 through the anti-disengagement protrusion 651 and the guide lock hole 641. The end of the key pin 65 away from the anti-disengagement protrusion 651 has an integrally formed screwing part 652. The end of the key pin 65 passing through the latch body 64 is screwed to a key pin permanent magnet 653 corresponding to the lock permanent magnet 632. Both the key pin permanent magnet 653 and the lock permanent magnet 632 are circular permanent magnets with the same magnetic pole area, and the key pin permanent magnet 653 and the lock permanent magnet 632 are arranged with the same pole facing each other. The anti-disengagement protrusion 651 can form an axial limit when the key pin 65 slides axially along the guide lock hole 641, effectively preventing the key pin 65 from slipping out of the latch body. The key pin 65 detaches from the lock and enters the guide groove 642 through the opening, moving along its trajectory. This causes the screwing part 652 to rotate while the key pin 65 rotates. At the same time, the key pin 65 also undergoes axial displacement in the same direction as the lock body 64, causing the key pin permanent magnet 653 to move closer to the lock permanent magnet 632. The repulsive magnetic force generated between the lock permanent magnet 632 and the key pin permanent magnet 653 can push the anti-theft lock 63 to rotate around the lock frame 61, causing the bolt 631 to separate from the stepped groove 211, thus unlocking the protective cover 3. When the key pin 65 is released, the anti-theft lock 63 resets under the elastic force of the return spring 62, and the bolt 631 engages with the stepped groove 211 again, re-locking. The entire unlocking and locking process does not require a complex mechanical lock cylinder structure, and compared with traditional lock structures, it is not easy to rust and jam.
[0032] The ABS electric valve protection well 2 is also provided with a clearance groove distributed around the well end 21. The ABS electric valve protection well 2 is set to avoid the solenoid valve connecting pipe on the solenoid valve body 1 through the clearance groove. The clearance groove is an arc-shaped groove structure to achieve clearance between the ABS electric valve protection well 2 and the connecting pipe, so as to avoid collision or interference between the protection well and the connecting pipe during the installation process, and ensure the normal layout and connection of the solenoid valve body 1 and the connecting pipe.
[0033] When using this device for well irrigation, the ABS electric valve protection well 2 and the well end 21 need to be connected by flange disassembly. The protective cover 3 is rotatably connected to the well end 21 through the pivot pin 31. The arc-shaped clearance groove opened around the circumference of the ABS electric valve protection well 2 is precisely aligned with the connecting pipe of the solenoid valve body 1 to achieve clearance and cooperation with the connecting pipe. When the focusing plate 51 is installed on the protective cover 3, the sealing ring 52 is tightly squeezed between the inner wall of the protective cover 3 and the outer wall of the focusing plate 51 to form a closed annular sealing structure, which can effectively block external dust and water vapor from entering the device through the gap between the focusing plate 51 and the protective cover 3, thus completing the complete protection of the solenoid valve body 1. The system is powered by solar energy. The power supplied to the solenoid valve body 1 and its own control system comes from the autonomous collection and conversion of solar energy. The high-transmittance lens 4 at the sun-facing end ensures that natural light passes through without loss. After the light enters the transparent light-concentrating plate 51, which is precisely aligned with the lens, the hemispherical light-concentrating spheres 511 arranged in a ring on its inner wall use the light-concentrating principle of convex lenses to converge the natural light at different incident angles, so that the light is concentrated onto the solar panel 53 below the light-concentrating plate 51, which greatly improves the photoelectric conversion efficiency. After the solar panel 53 converts the light energy into electrical energy, it is stored in the battery 7 inside the protective cover plate 3. The battery 7 provides a continuous and stable power supply to the controller body 8 and the solenoid valve body 1. The controller body 8 realizes intelligent on / off control of the solenoid valve body 1 through the control power line 9. At the same time, it is electrically connected to the antenna 54 outside the solar panel 53 to complete remote signal transmission. The staff can realize remote monitoring and operation of the solenoid valve body 1. During this process, the anti-theft mechanism 6 remains locked in the non-operational state. It relies on the elastic force of the return spring 62 to limit and lock the protective cover 3 and the well end 21. In the normal state, the return spring 62 is in a slightly compressed state, and its two ends abut against the spring retaining ring 611 of the lock frame 61 and the anti-theft lock 63, respectively, to provide a continuous elastic driving force for the anti-theft lock 63, pushing the anti-theft lock 63 to rotate around the lock frame 61, so that the locking tongue 631 at the bottom of the anti-theft lock 63 precisely engages with the stepped groove 211 of the well end 21. After engagement, it can restrict the rotation and opening of the protective cover 3, realize the anti-theft protection of the solenoid valve body 1 inside the well end 21, and prevent unauthorized personnel from illegally opening the protective cover 3. When unlocking and maintenance are required, the operator holds the screwing part 652 of the key pin 65 and pushes the key pin 65 axially along the guide lock hole 641 of the lock body 64. The anti-disengagement protrusion 651 on the key pin 65 slides along the guide lock hole 641 and forms an axial limit. After reaching the maximum movement distance, the operator rotates the key pin 65 according to the guide indication of the limit groove 6411, so that the anti-disengagement protrusion 651 enters the guide rotation groove 642 along the opening of the guide lock hole 641. The operator continues to screw the screwing part 652, causing the key pin 65 to rotate along the arc-shaped guide rotation groove 642. At the same time, the key pin 65 makes an axial displacement in the same direction, so that the key pin permanent magnet 653 at the end of the key pin 65 moves toward the lock permanent magnet 6 on the anti-theft lock 63. When the two magnets 62 and 62 are brought close together, a strong repulsive magnetic force is generated. This magnetic force overcomes the elastic force of the return spring 62 and pushes the anti-theft lock 63 to rotate in the opposite direction around the lock frame 61, causing the lock tongue 631 to separate from the step groove 211. This releases the locking engagement between the protective cover 3 and the well end 21. At this time, the protective cover 3 can rotate flexibly around the pivot pin 31 to open, facilitating inspection and maintenance. After the staff completes the inspection of the solenoid valve body 1 or electrical components inside the well, they release the key pin 65. The elastic force of the return spring 62 pushes the anti-theft lock 63 to rotate again, and the lock tongue 631 re-engages with the step groove 211. The device returns to its normal locking state without the need for manual locking.
