The diameter of the opening 27 is 15 cm-20 cm.

The top surfaces of the well seat 1 and the well lid 2 are on the same horizontal plane.

The first spring 6 and the second spring 13 are both compression springs.

The working principle is as follows: when the well lid 2 is installed, two inserted rods 23 fixedly connected with the bottom end of the well lid 2 are inserted into through holes formed in the cross rod 3 and the conical cylinder 4, the well lid 2 is slowly descended and placed in the well base 1, the inserted rods 23 fixedly connected with the bottom surface of the well lid 2 synchronously descend in the process that the well lid 2 slowly descends, the bottom surfaces of the inserted rods 23 are gradually and tightly attached to the inclined surfaces of the clamping blocks 21, thrust is generated on the inclined surfaces of the clamping blocks 21 in the process that the inserted rods 23 push the sliding plates 19 to slide on the fixing rods 7 until the well lid 2 is completely placed in the well base 1, the inserted rods 23 also descend to the lowest end, the clamping blocks 21 are arranged opposite to the insertion holes 22, the clamping blocks 21 are pushed to be inserted into the insertion holes 22 under the action of the first springs 6, and when the well lid 2 is taken upwards, the clamping blocks 21 are inserted into the insertion holes 22 and fixed and cannot be taken upwards, and then fix the well lid 2 on the well base 1 effectively, so no matter how to take the well lid 2, and pass horizontal pole 3 and conical cylinder 4 setting through two inserted bars 23 all laminating, so can avoid the well lid 2 producing rocking in the driving effectively, further strengthen the stability of the well lid 2, after the well lid 2 is placed in the well base 1 completely, the bottom surface of the well lid 2 and the sealing rubber layer equipped on the top surface of the cover 11 are closely laminated, at this moment, as the state shown in figure 1, in rainy day, the rainwater flows into between conical cylinder 4 and cover 11 through a plurality of lower water holes 24, then slide to between cylinder 34 and cover 11 along the inclined plane of the cylinder 4, then continue to fall to the shaft bottom, so can protect other device parts to get rusty when water, influence its life, and in the process of rainwater whereabouts, the arrangement of the sleeve 10 can effectively protect the steel wire 17 from contacting with water, and the service life of the sleeve is shortened; when the well lid 2 is damaged and needs to be replaced, firstly, the fixing bolt 26 is screwed off, then the lid body 25 is taken off from the well lid 2, then a worker puts hands into the opening 27, screws the different second handles 31 one by one, and further rotates the different threaded rods 36, in the process of rotating the different threaded rods 36, the threaded cylinders 33 in threaded connection with the bottom ends of the threaded rods 36 move downwards under the arrangement of the fixing blocks 37 and the guide rods 38, the distance of downward movement of each threaded cylinder 33 with different lengths is different, the distance of the movement is determined according to the number of turns of the threaded rods 36 rotated by the worker, the number of turns of the different threaded rods 36 is different, further, the distance of descending the threaded cylinders 33 in threaded connection on the threaded rods 36 is different, and further, the threaded cylinders 33 descending different heights are extended into the third through holes 44 arranged on the rotating disc 46, and the bottom surfaces of the thread cylinders 33 which descend to different heights are all aligned with the bottom surface of the rotary disc 46, when the thread cylinders 33 extend into the third through holes 44, the bottom ends of the thread cylinders 33 push the slide rods 40 to descend to extrude the second springs 13, when the bottom surfaces of the thread cylinders 33 are aligned, the top surfaces of the slide rods 40 which are different in length are also aligned and aligned with the top surface of the support plate 16, then the bolts 42 are unscrewed from the second through holes 41 and the thread blocks 43, the circular disc 32 is rotated under the arrangement of the dovetail ring 29 through the first handle 30, the rotary disc 46 is synchronously rotated under the arrangement of the threaded rod 36, the fixed block 37 and the guide rod 38, the steel wire 17 fixedly connected on the rotary disc 46 is pulled to wind on the rotary disc 46, meanwhile, one end of the steel wire 17 pulls the sliding plate 19 to slide to one side on the fixed rod 7, and further pulls the clamping blocks 21 fixedly connected on the sliding plate 19 to slide out of, at the moment, as shown in a state of figure 4, the well lid 2 can be directly pulled upwards, the well lid 2 and the inserted link 23 are moved upwards to be taken out from the well base 1, a new well lid 2 is installed, when external force is released, one end of the steel wire 17 is pulled under the arrangement of the first spring 6 to enable the rotating disc 46 to return to the original state, the sliding rod 40 is always attached to the bottom surface of the threaded cylinder 33 to be inserted into the third through hole 44 again under the action of the second spring 13 in the process of lifting the threaded cylinder 33, the rotating disc 46 is fixed on the supporting plate 16, each well base 1 is provided with a number, when the well lids 2 of the well bases 1 with different numbers are taken, the rotating turns of the plurality of internal threaded rods 36 are different, so that municipal workers can conveniently record the left ends, the phenomenon that the rotating turns of the plurality of internal threaded rods 36 need to be forgotten or confused due to long time is avoided, and in the installation process of the well, the operation is simple and quick, so that the working time is effectively saved, and meanwhile, the anti-theft effect is also effective.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
