[0025] During work, when workers need to go down to the bottom of the well for inspection or silt removal, the workers can stand on the support plate 21, and another worker connects the first drive assembly to the wellbore 2. When the first drive assembly drives the screw 23 to rotate, under the action of the threaded force, the slider 211 drives the support plate 21 to move up and down, so that the workers on the support plate 21 can go down into the well. When the work down the well is completed, the first drive assembly is separated from the wellbore 2 and stored in a dry environment.

[0026] The above structure is set up by setting a sliding groove 22 on the side wall of the wellbore 2 and setting a slider 211 on the support plate 21, so that the support plate 21 can be slidably connected with the sliding groove 22 in the longitudinal direction, a screw 23 threadedly connected to the slider 211 is set, and a first driving component that can drive the screw to rotate is set on the wellbore 2, so that when the motor 4 is working, it can drive the screw 23 to rotate, and the thread force of the rotation of the screw 23 can drive the slider 211 to move up and down, so that the support plate 21 can drive the workers up and down, making it convenient and safe for the workers to go down the well, and the first driving component is set to be detachably connected to the wellbore 2, so that the first driving component can be disassembled when not in use, and will not be affected by the humid environment in the well and reduce the service life.

[0029] During operation, align the second bolt hole of the motor 4 with the first bolt hole 24 of the wellbore 2. Both the first bolt hole 24 and the second bolt hole are provided with multiple ones. Bolts are used to fix the motor to the wellbore 2. At this time, the block 2311 is correspondingly connected with the slot of the screw 23, so that the motor 4 can be driven to drive the screw 23 to rotate.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, the support plate 21 is provided with ventilation holes 212, the bottom of the support plate 21 is rotatably connected with ventilation blades 213, and a second driving component is provided between the wellbore 2 and the support plate 21, which can transmit power to the ventilation blades 213 when the support plate 21 is raised or lowered.

[0031] The above structure is arranged by arranging ventilation blades 213 at the bottom of the support plate 21, and arranging a second driving component on the wellbore 2 to drive the ventilation blades 213 to rotate. When the support plate is raised or lowered, the second driving component can drive the ventilation blades 213 to rotate. When the ventilation blades 213 rotate, the air in the well can be stirred, so that the air in the well and the outside air can flow more smoothly.

[0032] In this embodiment, Figure 4As shown, the second driving assembly includes a first rotating wheel 214, a first fixed block is arranged on the side wall of the support plate 21, the first rotating wheel 214 is rotatably connected to the first fixed block, the side wall of the first rotating wheel 214 abuts against one of the sliding slots 22, the axis of the first rotating wheel 214 is perpendicular to the length direction of the sliding slot 22, a first gear ring 2141 is arranged at one end of the first rotating wheel 214, the bottom of the support plate 21 is rotatably connected to the second rotating wheel 215, the lower end of the second rotating wheel 215 is provided with a second gear ring 2151, the ventilation blade 213 includes a rotating shaft 2131, the rotating shaft The top of 2131 is fixedly connected to the second rotating wheel 215, and a plurality of blades are arranged in an array along the outer peripheral wall of the rotating shaft 2131, and a connecting block 216 is fixedly connected to the bottom of the support plate 21, and a second rotating groove is penetrated through the connecting block 216, and a transmission rod 2161 is rotatably connected in the second rotating groove, and a first tooth block 21611 and a second tooth block 21612 are respectively arranged at both ends of the transmission rod 2161, the first tooth block 21611 is meshed with the first gear ring 2141, and the second tooth block 21612 is meshed with the second gear ring 2151.

[0033] Specifically, the number of the sliders 211 can be set to be one less than the number of the sliding slots 22 , so that one of the sliding slots 22 is not slidably connected to the slider 211 , and the first rotating wheel 214 is set to abut against this sliding slot 22 .

[0034] During operation, since the first rotating wheel 214 is against the sliding groove 22, the first rotating wheel 214 rotates when the support plate 21 descends. Since the first rotating wheel is provided with a first gear ring 2141, and the first gear ring 2141 is meshed with the first tooth block 21611 of the transmission rod 2161, the first rotating wheel 214 drives the transmission rod 2161 to rotate when it rotates, and the other end of the transmission rod 2161 is meshed with the second gear ring 2151, so that the ventilation blades 213 can be synchronously driven to rotate when the support plate 21 is raised or lowered. Before the workers go down the well, they need to raise or lower the support plate 21 several times. On the one hand, they can test whether the lifting of the support plate 21 can be used normally, and on the other hand, they can further ventilate the well to ensure the safety of the construction environment.

[0035] The above structure, by setting the transmission rod 2161, the first gear ring 2141 and the second gear ring 2151, can synchronously drive the ventilation blades 213 to rotate when the support plate 21 is raised or lowered, without setting up another driving device for the ventilation blades 213, thereby saving energy.

[0036] In this embodiment, Figure 1As shown, a construction groove is provided on the support plate 21 , a cover plate 217 which can close the construction groove is hinged on the support plate 21 , and a support plate which can support the edge of the cover plate 217 is provided at the bottom of the support plate 21 .

[0038] During work, when workers go down to the bottom of the well, they can lift up the cover plate 217 to inspect and desilt the bottom of the well.

[0039] The above structure is set up by setting a cover plate 217 on the support plate 21, so that workers can open the cover plate 217 to facilitate construction, and can cover the cover plate 217 during lifting to make the standing space larger and more stable, thereby preventing the workers from falling due to the bumps during the lifting process.

[0040] The above structure is arranged by arranging rectangular grooves around the slot 231 so that the block 2311 can be slidably connected with the rectangular groove, the block can slide out of the slot, and the screw rod 23 can rotate with the block 2311.

[0041] In this embodiment, the shaft 2 includes a plastic inner shell 25 and a plastic outer shell 26 , and a concrete layer 27 is provided between the plastic inner shell 25 and the plastic outer shell 26 .

[0042] Specifically, a connection block 216 is provided between the plastic inner shell 25 and the plastic outer shell 26 , and then concrete is poured between the plastic inner shell 25 and the plastic outer shell 26 to form a concrete layer 27 .

[0043] The above structure is arranged by arranging the shaft 2 to include a plastic inner shell 25 and a plastic outer shell 26, and arranging a concrete layer 27 between the plastic inner shell 25 and the outer shell. The plastic inner shell 25 and the plastic outer shell 26 have good anti-corrosion and mildew resistance, and the concrete layer 27 makes the shaft 2 have good strength.

[0044] In this embodiment, a manhole cover 3 is hingedly connected to the top of the shaft 2 , and the manhole cover 3 includes an upper cover 31 and a lower cover 32 that are hingedly connected to each other, and a drainage hole 321 is provided on the lower cover 32 .

[0045] The above structure is arranged by setting the manhole cover 3 to include an upper cover 31 and a lower cover 32 which are hinged to each other, and arranging a drainage hole 321 on the lower cover 32, so that when the water level is high, the upper cover 31 can be opened and the accumulated water can be discharged through the drainage hole 321. Under normal circumstances, the upper cover 31 is covered so that the odor in the well will not pollute the air near the inspection well. It should be noted that both the lower cover 32 and the upper cover 31 have sufficient strength.

[0046] In this embodiment, two screw rods 23 are provided, and two sliders 211 connected to the two screw rods 23 are opposite to each other. The number of the first driving components matches the number of the screw rods 23 .
