[0011] In the above-mentioned solar manhole cover, the upper side surface of the disassembly block has a wedge-shaped surface to facilitate the axial movement of the disassembly block.

[0012] In the above-mentioned solar manhole cover, the sliding telescopic rod is rotatably connected to the rigid rod via a rotating shaft, and a second torsion spring is arranged on the rotating shaft to maintain the abutting rod in the abutting position.

[0030] In this embodiment, a solar panel is provided on the upper surface of the shell, and the solar panel is used to convert solar energy into electrical energy. The electrical energy is used to power various devices in the shell, such as sensors used to detect various parameters in the well. At the same time, an emergency power supply and a communication module are provided inside the shell. The emergency power supply is used to store excess electrical energy for daily emergency use, and the communication module is used for remote communication to remotely transmit the information detected by the sensor.

[0031] Specifically, the cover body 1 is installed on the well seat 2 by rotating connection, and the well seat 2 is fixed on the ground. The shape of the cover body 1 is circular, and a cylindrical body 14 is formed in the inner central area of ​​the cover body 1, and a center hole 3 is formed on the inner side of the cylindrical body 14. A plurality of slide grooves 9, such as 2-4, are arranged on the inner wall of the center hole 3 along the circumferential direction, and the slide groove 9 extends axially along the cylindrical body 14. A disassembly block 8 is slidably connected in the slide groove 9, and a groove 8.1 adapted to the sealing ring 5 is formed on the disassembly block 8. The other end of the disassembly block 8 extends radially to the outside of the cylindrical body 14, and the extended part is a protrusion 15. The shape of the shell 4 carrying the solar panel is cylindrical to adapt to the shape of the center hole 3, and a sealing ring 5 is arranged on the outer wall of the shell 4. The shell 4 is sealed and connected to the center hole 3 through the sealing ring 5. At this time, since a plurality of disassembly blocks 8 are arranged circumferentially on the hole wall of the center hole 3, a part of the sealing ring 5 is correspondingly located in the groove 8.1 on the disassembly block 8. It also includes a locking mechanism, the number of which is the same as the number of disassembly blocks 8 and is arranged in a one-to-one correspondence, and multiple locking mechanisms are evenly arranged in the circumferential direction of the cover body, the locking mechanism includes an integrated abutment rod 6 and a sliding telescopic rod 7, the abutment rod 6 and the sliding telescopic rod 7 form a V-shaped structure, the sliding telescopic rod 7 is a rod that can be axially elastically extended and retracted, this is the prior art and is not repeated, the abutment rod 6 is swingably connected to a support frame arranged on the inner side of the cover body 1, that is, it is directly swingably connected to the outer edge of the bottom of the cylindrical body through a rotating shaft, that is, the abutment rod 6 is rotatably connected to a foundation through a rotating structure such as a rotating shaft, and a first torsion spring (not shown in the figure) is arranged on the rotating shaft, the first torsion spring is used to maintain the abutment rod in the abutment position, in the abutment position, the end of the abutment rod 6 presses against the inner wall of the cover body 1 to achieve auxiliary limiting, so that the shell 4 is sleeved in the center hole 3 and the abutment rod 6 abuts on the inner side surface of the shell 4 to lock the shell 4 in the center hole 3.

[0032] One end of the sliding telescopic rod away from the abutment rod 6 is rotatably connected to a rigid rod 12 via a rotating shaft 13, and the other end of the rigid rod 12 abuts against a raised portion 15 of the disassembly block 8. A second torsion spring (not shown in the figure) is provided on the rotating shaft 13. The second torsion spring is used to maintain the relative angle between the rigid rod 12 and the sliding telescopic rod 7, that is, it is located in the initial abutment position. At this time, the end of the rigid rod 12 abuts against the top surface of the raised portion of the disassembly block 8. A sliding groove is preferably provided on the inner surface of the cover body 1. The sliding groove is used for the linear sliding of the part of the sliding telescopic rod 7 provided with the rotating shaft 13 on the inner wall of the cover body 1. In the swing stroke of the abutment rod 6, there is an abutment position where the abutment rod 6 abuts against the shell 4 and a disassembly position where the disassembly block 8 is separated from the sliding groove 9. In the abutting position, the abutting rod 6 abuts against the inner side surface of the shell 4, the disassembly block 8 is located in the slide groove, and the sealing ring 5 is sealed and connected to the groove 8.1 on the disassembly block 8. At this time, the locking mechanism is in a locked state, that is, the shell 4 is locked in the center hole 3. In the disassembly position, the abutting rod 6 is pulled to disengage from the inner side surface of the shell 4, and is pulled a certain distance so that the shell 4 has an axial displacement space to disengage from the center hole 3. The swing of the abutting rod 6 will drive the sliding telescopic rod 7 to swing. At this time, the end of the sliding telescopic rod 7 will abut the inner wall of the cover body 1 (the end of the sliding telescopic rod 7 at the abutting position has a certain gap with the inner wall of the cover body 1), that is, the end of the sliding telescopic rod 7 slides linearly in the sliding groove on the inner wall of the cover body 1 due to the rotation and extension of the sliding telescopic rod 7. Figure 4-5 As shown, at this time, the length of the sliding telescopic rod 7 will be reduced. Due to the rigid material of the rigid rod 12, the end of the sliding telescopic rod 7 slides and drives one end of the rigid rod 12 to slide synchronously, so that the other end of the abutting protrusion 15 of the rigid rod 12 moves in the direction away from the inner wall of the cover body 1, that is, the rigid rod 12 will drive the disassembly block 8 to move axially along the inner wall of the slide groove 9. At this time, the disassembly block 8 will drive the sealing ring 5 and the shell 4 to move axially as a whole until the shell 4 is separated from the center hole to complete the disassembly, so that the abutting rod 6 is pulled out of the shell, and at the same time as the abutting rod 6, the disassembly block 8 can also be passively moved axially so that the shell 4 is separated from the center hole 3. At this time, the locking mechanism is in an unlocked state. In this embodiment, the length and position of the abutting rod 6, the sliding telescopic rod 7, the rigid rod 12 and the slide groove 9 are set so that the abutting rod 6 leaves the inner side of the shell 4 for a distance, and then the shell 4 is separated from the center hole 3. In this way, adding a locking mechanism not only improves the stability of the structure, but also greatly simplifies the operation process of maintaining and replacing solar panels.

[0033] In this embodiment, since there is a certain gap between the end of the sliding telescopic rod 7 and the inner wall of the cover body 1 at the abutment position, during the unlocking process, the abutment rod 6 is first separated from the abutment with the shell 4, and then the rigid rod 12 drives the disassembly block 8. This has a time difference and avoids the negative resistance caused by the abutment of the abutment rod 6 at this time.

[0034] A solar manhole cover provided by an embodiment of the present invention comprises: the shell 4 abuts against the groove of the disassembly block 8 through the sealing ring 5 and the abutting rod abuts against the inner side surface of the shell so as to lock the shell in the center hole. When the shell 4 needs to be disassembled, the abutting rod 6 is pulled to disengage from the inner side surface of the shell. At this time, the abutting rod will drive the sliding telescopic rod 7 to swing while shortening its length. At this time, the end of the sliding telescopic rod will abut against the inner wall of the cover body. In this way, the sliding of the end of the sliding telescopic rod drives one end of the rigid rod to slide synchronously. At this time, the rigid rod will drive the disassembly to move axially along the inner wall of the slide groove. At this time, the disassembly block will drive the sealing ring and the shell as a whole to move axially until the shell is separated from the center hole to complete the disassembly. In this way, the disassembly block can be passively moved only by the swing of the abutting rod, thereby achieving the purpose of disassembling the entire shell 4.

[0035] In another embodiment provided by the present invention, it is obvious that in order to maintain the squeezing force of the abutting position of the abutting rod 6, the elastic force of the first torsion spring is relatively large, which requires a large force to pull the abutting rod 6 to switch the state, and the manual force may be difficult to meet. Correspondingly, a ring 11 is fixedly connected to the abutting rod. When repairing the manhole cover, the maintenance worker will lift the cover body through the manhole cover hook 10. The manhole cover hook 10 is a prior art and will not be repeated. At this time, the ring 11 can be hooked by the manhole cover hook 10 and pulled away from the center hole 3, so that the abutting rod 6 will also be away from the shell 4, so that the abutting rod 6 will also have a swing stroke. The purpose of setting the ring 11 is that it is more convenient and quick to pull the ring 11 by means of the prior art such as the manhole cover hook 10, and a large pulling force can be applied. In this embodiment, in order to quickly disassemble, two groups of the above-mentioned disassembly structures are preferably provided. During disassembly, two workers pull the two rings 11 at the same time relative to each other, so that the shell 4 can be quickly disassembled.

[0036] In another embodiment provided by the present invention, Figure 6As shown, when the abutment rod 6 is in the abutment position, that is, when the shell is in the locked state, the end of the rigid rod 12 away from the rotating shaft 13 can be manually pulled to the bottom of the protrusion 15. Since the rigid rod 12 is rotatably connected to the rotating shaft 13 and the length of the rigid rod 12 is certain, when the abutment rod 6 is in the abutment position, the rigid rod 12 will also abut on the disassembly block 8. Under the action of the second torsion spring, the rigid rod 12 forms an extrusion force toward the top side of the shell on the disassembly block 8, thereby having an auxiliary limiting effect, thereby forming a double abutment limit for the shell 4, increasing the locking effect of the shell 4, and when the shell 4 needs to be separated from the center hole 3, since the rotating shaft 13 and the inner wall of the cover body 1 still have a certain moving space, it is only necessary to manually move the rigid rod 12 to the top of the protrusion 15, which can drive the disassembly block 8 to move downward under the push of the sliding telescopic rod 7 to complete the subsequent unlocking operation of the shell 4.

[0037] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
