The lower side of the lower shell 4 is provided with a circular convex surface 5. The middle part of the circular convex surface 5 is provided with a water-permeable net 6. The water-permeable net 6 is a waterproof and breathable net that can replace the gas inside the terminal body 1, thereby dissipating the gas and heat inside the terminal body 1, reducing the risk of water vapor corrosion of components;

[0025] A fixing plate 7 is fixedly connected to the upper side of the fixing frame 2. A plurality of clamping blocks 8 are provided inside the fixing frame 2 for radial movement along the fixing frame 2. The clamping blocks 8 cooperate with the terminal body 1 to form a structure for disassembling the terminal body 1.

[0026] The terminal body 1 is internally provided with various hardware of the monitoring terminal. The intelligent manhole cover terminal is a prior art and will not be described in detail here.

[0027] Further, by Figure 1 and Figure 3 As shown, in order to facilitate the installation of the device, a rotatable power disc 9 is provided inside the fixed frame 2, and a limiting area 10 is provided on the lower side of the power disc 9 corresponding to the position of each block 8;

[0028] When in use, the gas inside the terminal body 1 can be promptly released through the water-permeable net 6, reducing the risk of water vapor corroding components. When the device is installed, the fixing plate 7 is fixedly connected to the bottom of the manhole cover by welding. When the terminal body 1 needs to be installed, each block 8 can be used to limit the terminal body 1 downward.

[0029] Further, by Figure 1 - Figure 3As shown, in order to facilitate the operation of the staff, the limiting area 10 includes a placement area 11, a locking area 12 and an unlocking area 13 that are interconnected. The locking area 12 and the unlocking area 13 are respectively located on both sides of the placement area 11. The block 8 can move freely in the radial direction of the fixed frame 2 within the placement area 11;

[0030] Further, by Figure 1 - Figure 3 As shown, the upper end of each clamping block 8 is fixedly connected to a cylindrical block 14, and each cylindrical block 14 is slidably connected to the limiting area 10;

[0031] Further, by Figure 1 - Figure 3 As shown, each block 8 is provided with a return spring 15 on the side away from the axis of the fixed frame 2, and each block 8 is provided with an inclined surface 16 on the bottom of the side away from the return spring 15;

At this time, when the terminal body 1 is pushed upward, the outer periphery of the terminal body 1 will push each card block 8 to move under the action of the inclined surface 16. At this time, each return spring 15 accumulates force, and when the middle part of the terminal body 1 passes through the upper side plane of the card block 8, each return spring 15 pushes each card block 8 to reset, and the terminal body 1 is limited by the upper side plane of each card block 8. After installation, the power disc 9 can be rotated so that the locking area 12 is aligned with each cylindrical block 14. At this time, the cylindrical block 14 can be limited by the locking area 12. When unlocking is required, the power disc 9 can be rotated in the opposite direction so that the unlocking area 13 is aligned with each cylindrical block 14. At this time, under the action of the unlocking area 13, each card block 8 will be driven to move through each cylindrical block 14, thereby releasing the limit of the terminal body 1, and the terminal body 1 can be removed for inspection.

[0034] Further, by Figure 1 - Figure 3 As shown, in order to facilitate the operation of the staff, a power rod 18 is fixedly connected to the right side of the power disc 9, and a power slot 19 is opened at the position of the fixed frame 2 corresponding to the power rod 18. The middle part of the power rod 18 passes through the power slot 19 for the staff to operate;

[0035] When in use, the power disc 9 can be driven to rotate by toggling the power rod 18 .

The first locking plate 21 and the second locking plate 22 cooperate with each other to form a structure for protecting the power rod 18; a circular hole is opened in the middle of each of the first locking plate 21 and the second locking plate 22;

[0037] During use, a safety lock may be provided between the first locking plate 21 and the second locking plate 22 to increase the safety of the device.

[0038] When the present invention is used, first, when the device is installed, the fixing plate 7 is fixedly connected to the bottom of the manhole cover by welding. When the terminal body 1 needs to be installed, each cylindrical block 14 is located in the placement area 11 of the corresponding limit area 10. Each cylindrical block 14 can move radially along the fixed frame 2 in the placement area 11. At this time, when the terminal body 1 is pushed upward, the outer periphery of the terminal body 1 will push each block 8 to move under the action of the inclined surface 16. At this time, each reset spring 15 accumulates force. When the middle part of the terminal body 1 passes through the upper side plane of the block 8, each A reset spring 15 pushes each block 8 to reset, and the terminal body 1 is limited by the upper side plane of each block 8. After installation, the power disc 9 can be rotated to align the locking area 12 with each cylindrical block 14. At this time, the cylindrical block 14 can be limited by the locking area 12. When unlocking is required, the power disc 9 can be rotated in the opposite direction to align the unlocking area 13 with each cylindrical block 14. At this time, under the action of the unlocking area 13, each block 8 will be driven to move through each cylindrical block 14, thereby releasing the limit of the terminal body 1, and the terminal body 1 can be removed for maintenance.
