As shown in fig. 3, the worm 2-3-112 is in mesh transmission with the worm wheel 2-3-113 arranged in the supporting shell 2-3-117, the worm 2-3-112 is fixed in the supporting shell 2-3-117 by a first spring 2-3-119 and can move up and down in the supporting shell 2-3-117, the press cap 2-3-111 also moves up and down along with the worm 2-3-112, when sewage entering the shaft 1 from the water leakage hole 9-1 of the well cover falls onto the press cap 2-3-111, the press cap 2-3-111 is pressed by the sewage to move downwards, thereby driving the worm 2-3-112 to move downwards, and when no sewage falls, the worm 2-3-112 rebounds and lifts under the action of the first spring 2-3-119.
As shown in fig. 1, 2 and 3, in order to facilitate the sewage and the dirt mixed therein falling on the press cap 2-3-111 to smoothly flow downward from the surface of the press cap 2-3-111, in some embodiments, the edge of the press cap 2-3-111 is provided with a downward slope.
In order to facilitate the sewage and the dirt therein to fall on the pressing cap 2-3-111 intensively to press the pressing cap 2-3-111, as shown in fig. 1 and 2, in some embodiments, the manhole cover water leakage holes 9-1 formed in the manhole cover 9 are intensively arranged above the pressing cap 2-1-11.
In some embodiments, as shown in fig. 3, the first spring 2-3-119 is disposed in such a manner that a connection stage 2-3-110 is disposed on an inner sidewall of the support housing 2-3-117, and the first spring 2-3-119 is fixed at a top end thereof to the worm 2-3-112 and at a bottom end thereof to the connection stage 2-3-110. In some embodiments, as shown in fig. 3, the first springs 2-3-119 are disposed entirely within the support housing 2-3-117 in order to improve the cleanliness of the overall structure and also to avoid corrosion of the first springs 2-3-119 by contact with contaminated water.
As shown in fig. 3, the turbines 2-3-113 and the first sector gears 2-3-114 are disposed on reversing shafts 2-3-116, the reversing shafts 2-3-116 are disposed in the supporting housings 2-3-117, the first sector gears 2-3-114 and the second sector gears 2-3-115 are in meshing transmission, and the second sector gears 2-3-115 are disposed on the rotating rods 2-3-12. Therefore, the reversing rotating shaft 2-3-116 and the first sector gear 2-3-114 rotate along with the turbine 2-3-113, the first sector gear 2-3-114 drives the second sector gear 2-3-115 to rotate, the rotating rod 2-3-12 rotates along with the second sector gear 2-3-115, and finally the crushing blade 2-3-13 rotates to crush and cut large-particle dirt in the sewage.
In order to solve the problem that large-particle dirt in sewage or large-particle dirt flowing into a shaft 1 along with rainwater during initial rain is easy to block between a crushing blade 2-3-13 and the inner side wall of a dirt intercepting chamber 2-3 to prevent a rotary rod 2-3-12 from rotating when the large-particle dirt in the sewage is large in volume, so that the crushing device 2-3-1 cannot smoothly crush the large-particle dirt, in some embodiments, as shown in fig. 8, a mounting hole 2-3-14 is formed in the rotary rod 2-3-12, the end part of the crushing blade 2-3-13 is fixed in the mounting hole 2-3-14 through a second spring 2-3-15, namely the second spring 2-3-15 is sleeved outside the rotary rod 2-3-12, and the outer end of the second spring 2-3-15 is fixed on the rotary rod 2-3-12 The inner measuring end of the second spring 2-3-15 is fixed on the inner bottom of the mounting hole 2-3-13, so that when large-sized dirt is caught between the inner side wall of the dirt-intercepting chamber 2-3 and the crushing blades 2-3-13, the crushing blades 2-3-13 can retract inwards to enlarge the gap between the crushing blades 2-3-13 and the inner side wall of the sewage interception chamber 2-3, so that large-particle sewage can not be clamped between the crushing blades 2-3-13 and the inner side wall of the sewage interception chamber 2-3, when the stuck large-particle dirt is removed, the crushing blades 2-3-13 extend outwards to restore the original position under the action of the second springs 2-3-15, thereby enabling the crushing blades 2-3-13 to continuously crush and cut large-particle dirt.
