Finally, when the filter 3051 is flipped over, the filter 3051 is automatically cleaned for later reuse.

[0045] The shifting climbing unit 400 includes a push plate 401, which slides horizontally on the side wall of the inspection well body 201, and a ladder 4011 is installed on the push plate 401. A rocker arm 402 is rotatably installed on the side wall of the push plate 401, and the rocker arm 402 is rotatably connected to the side wall of the enclosure 305, and the rocker arm 402 is in an inclined state.

[0047] like Figures 1 to 10 As shown, further, a fence 2011 is installed around the inspection well body 201, and the wellhead 2012 is located on the inner side of the fence 2011. The fence 2011 can protect the inspection well body 201 on all sides. The upper surface of the inspection well body 201 is flush with the ground 2013. A fixed block 2022 is installed at the bottom of the inspection well body 201. The fixed block 2022 is interconnected with the outer shells of the thermal main pipe 202 and the thermal sub-pipe 2021.

[0048] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 10As shown, an anti-skid groove 3011 is provided on the manhole cover 301, and the anti-skid groove 3011 increases the friction force. Two countersunk grooves are symmetrically provided on the manhole cover 301, and a lifting ring 3013 is rotatably installed on the countersunk groove. The thickness of the lifting ring 3013 is smaller than the depth of the countersunk groove. The sizes of the manhole cover 301 and the wellhead 2012 correspond to each other. A rotating block 3012 is installed at one end of the manhole cover 301, and the rotating block 3012 is rotatably connected to the wellhead 2012. A positioning block 3014 is installed at the other end of the manhole cover 301. A mounting seat 3015 is welded on the inspection well body 201, and a clamping plate 3016 is rotatably installed on the mounting seat 3015, and the clamping plate 3016 covers the positioning block 3014. When the operator needs to enter the inspection well body 201 later, the operator needs to rotate the clamping plate 3016 to make the clamping plate 3016 rotate on the mounting seat 3015. When the clamping plate 3016 and the pressure plate 302 are separated, the lifting ring 3013 is pulled, and the lifting ring 3013 can drive the well cover 301 and the rotating block 3012 to rotate around the rotation center, and finally the well cover 301 can be opened to expose the wellhead 2012 to the outside, so that the operator can go up and down to inspect the well body 201 conveniently.

[0049] like Figures 1 to 10 As shown, in a specific embodiment, an installation cavity 3022 is provided on the manhole body 201, and a push rod 3021 is movably plugged into the installation cavity 3022. A positioning plate 3023 is installed on the installation cavity 3022. A baffle 3024 is slidably provided inside the installation cavity 3022. The baffle 3024 and the bottom of the push rod 3021 are connected to each other. A positioning spring 3025 is provided between the bottom of the baffle 3024 and the inner wall of the installation cavity 3022, and the positioning spring 3025 is sleeved on the outside of the push rod 303. When the manhole cover 301 rotates, the pressure plate 302 and the push rod 3021 on the manhole cover 301 are separated, achieving the purpose of unlocking. Under the action of the positioning spring 3025, the baffle 3024 is pushed to slide, and the baffle 3024 slides upward along the installation cavity 3022 until it moves to the position of the positioning plate 3023 and stops moving. During the movement of the baffle 3024, the push rod 303 at the bottom slides upward synchronously.

[0050] like Figures 1 to 10As shown, further, a synchronization rod 3031 is installed on the outer wall of the push rod 303, a slide rod 3032 is installed on the synchronization rod 3031, a strip groove 3041 is opened on the rocker 304, the strip groove 3041 and the slide rod 3032 are slidably connected, a clamping seat 3042 is rotatably installed at one end of the rocker 304, and the clamping seat 3042 is welded to the inner wall of the inspection well body 201, and a connecting seat 3043 is installed on the side wall of the rocker 304, and the connecting seat 3043 is welded to the side wall of the enclosure 305. During the upward movement of the push rod 303, the synchronization rod 3031 and the slide rod 3032 on the side wall of the push rod 303 slide in the strip groove 3041 of the rocker 304, and then the slide rod 3032 can drive the rocker 304 to rotate as a whole, and the side wall of the rocker 304 can rotate around the clamping seat 3042, and the rocker 304 can also drive the connecting seat 3043 and the enclosure 305 to rotate. At this time, the enclosure 305 rotates around the bottom of the wellhead 2012, and the filter screen 3051 on the enclosure 305 rotates synchronously. The filter screen 3051 is separated from the wellhead 2012 at this time, which is convenient for maintenance personnel to climb.

[0051] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 10 As shown, a collecting box 3052 is installed on the side wall of the enclosure 305, a limiting plate 3061 is installed on the insertion rod 306, a compression spring 3062 is sleeved on the insertion rod 306, one end of the compression spring 3062 is clamped on the side wall of the enclosure 305, and the other end of the compression spring 3062 is clamped on the limiting plate 3061, and a guide wheel 3064 is installed on the limiting plate 3061, and the guide wheel 3064 is fitted with the extrusion track 307, and the depth of the extrusion track 307 on the side close to the wellhead 2012 is greater than the depth on the other side. During the rotation of the enclosure 305, the positions of the insertion rod 306 and the guide wheel 3064 on the enclosure 305 change synchronously, wherein the guide wheel 3064 slides on the extrusion track 307, so when the insertion rod 306 slides along the extrusion track 307, the insertion rod 306 as a whole moves toward the enclosure 305, and the limit plate 3061 can compress the compression spring 3062, and the compression spring 3062 is used to facilitate later resetting. When the insertion rod 306 moves, it can push the scraper 3063 at the end to slide, and the scraper 3063 can slide on the surface of the filter 3051, and finally the impurities on the filter 3051 can be pushed into the collection box 3052 for collection, so that the filter 3051 can be reused.

[0052] like Figures 1 to 10As shown, in a specific embodiment, an anti-slip sleeve is installed on the ladder 4011, and a synchronous plate 4021 is rotatably installed at the end of the rocker arm 402, and the synchronous plate 4021 is welded and set on the side wall of the enclosure 305. When the enclosure 305 rotates, the position of the synchronous plate 4021 on the enclosure 305 changes synchronously, and the rocker arm 402 rotatably connected to the synchronous plate 4021 drives the push plate 401 to slide horizontally, and then the push plate 401 drives the ladder 4011 to move below the wellhead 2012, which is convenient for later climbing, and after moving to the designated position, the push plate 401, the enclosure 305 and the rocker arms 402 on both sides will enclose a rectangular space, thereby protecting the climbing personnel and improving the safety during the climbing process.

[0053] like Figures 1 to 10 As shown, further, a reset sleeve 403 is installed on the side wall of the inspection well body 201, and the reset sleeve 403 is placed in an inner groove 4012 opened on the side wall of the push plate 401, and a partition 4032 is slidably arranged inside the reset sleeve 403, and a reset rod 4031 is installed at one end of the partition 4032, and the reset rod 4031 movably passes through the reset sleeve 403, and the end of the reset rod 4031 and the inner wall of the inner groove 4012 are connected to each other, and a reset spring 4033 is installed on the other end of the partition 4032, and one end of the reset spring 4033 is clamped on the inner wall of the reset sleeve 403, and the other end of the reset spring 4033 is clamped on the partition 4032, and the compression direction of the reset spring 4033 and the moving direction of the reset rod 4031 are on the same straight line. When the push plate 401 slides, the inner groove 4012 on the push plate 401 can slide out from the outer wall of the reset sleeve 403, and at this time the reset rod 4031 pulls the partition 4032 to slide, the partition 4032 can slide inside the reset sleeve 403, and the compressed reset spring 4033 is restored to its initial state.

[0054] The implementation principle of a manhole suitable for laying thermal pipelines on the roof of a basement in this embodiment is as follows:

[0055] When it is raining outside, rainwater may flow into the manhole body 201 along the gap of the wellhead 2012. During the flow, rainwater and the garbage carried by rainwater will fall onto the filter 3051. The filter 3051 can filter the impurities in the rainwater, and the filtered rainwater can be discharged outward through the drainage pipe inside the manhole body 201. When the rainwater falls, the ladder 4011 is not located below the wellhead 2012, so the rainwater will not fall directly onto the ladder 4011, which is less corrosive to the ladder and makes the subsequent climbing safer.

[0056] When the operator needs to enter the inspection well body 201 later, the operator needs to rotate the clamping plate 3016 to make the clamping plate 3016 rotate on the mounting seat 3015. When the clamping plate 3016 and the pressure plate 302 are separated, the lifting ring 3013 is pulled, and the lifting ring 3013 can drive the well cover 301 and the rotating block 3012 to rotate around the rotation center, and finally the well cover 301 can be opened to expose the wellhead 2012 to the outside, so that the operator can go up and down to inspect the well body 201 conveniently.

[0057] When the manhole cover 301 rotates, the pressure plate 302 and the top rod 3021 on the manhole cover 301 are separated, thereby achieving the purpose of unlocking. The baffle plate 3024 is pushed to slide under the action of the positioning spring 3025, and the baffle plate 3024 slides upward along the installation cavity 3022 until it moves to the position of the positioning plate 3023 and then stops moving. During the movement of the baffle plate 3024, the push rod 303 at the bottom slides upward synchronously.

[0058] During the upward movement of the push rod 303, the synchronization rod 3031 and the slide rod 3032 on the side wall of the push rod 303 slide in the strip groove 3041 of the rocker 304, and then the slide rod 3032 can drive the rocker 304 to rotate as a whole, and the side wall of the rocker 304 can rotate around the clamping seat 3042, and the rocker 304 can also drive the connecting seat 3043 and the enclosure 305 to rotate. At this time, the enclosure 305 rotates around the bottom of the wellhead 2012, and the filter screen 3051 on the enclosure 305 rotates synchronously. The filter screen 3051 is separated from the wellhead 2012 at this time, which is convenient for maintenance personnel to climb.

[0059] During the rotation of the enclosure 305, the positions of the insertion rod 306 and the guide wheel 3064 on the enclosure 305 change synchronously, wherein the guide wheel 3064 slides on the extrusion track 307, so when the insertion rod 306 slides along the extrusion track 307, the insertion rod 306 as a whole moves toward the enclosure 305, and the limit plate 3061 can compress the compression spring 3062, and the compression spring 3062 is used to facilitate later resetting. When the insertion rod 306 moves, it can push the scraper 3063 at the end to slide, and the scraper 3063 can slide on the surface of the filter 3051, and finally the impurities on the filter 3051 can be pushed into the collection box 3052 for collection, so that the filter 3051 can be reused.

[0060] When the enclosure 305 rotates, the position of the synchronization plate 4021 on the enclosure 305 changes synchronously, and the rocker arm 402 rotatably connected to the synchronization plate 4021 drives the push plate 401 to slide horizontally, and then the push plate 401 drives the ladder 4011 to move to the bottom of the wellhead 2012, which is convenient for subsequent climbing. After moving to the designated position, the push plate 401, the enclosure 305 and the rocker arms 402 on both sides will form a rectangular space, thereby protecting the climbing personnel and improving the safety during the climbing process.

[0061] When the push plate 401 slides, the inner groove 4012 on the push plate 401 can slide out from the outer wall of the reset sleeve 403, and at this time the reset rod 4031 pulls the partition 4032 to slide, the partition 4032 can slide inside the reset sleeve 403, and the compressed reset spring 4033 is restored to its initial state.
