Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A municipal rainwater drainage structure is shown in figures 1 and 2 and comprises a sewer 1 arranged below the ground 14 and an inspection well 2 communicated with the sewer 1, wherein the inspection well 2 is arranged in a cylindrical shape. Specifically, the inspection well 2 comprises an inspection well opening 21, a grid net 3 is arranged at the inspection well opening 21 of the inspection well 2, and the grid net 3 is flush with the ground 14. Grid net 3's bottom surface is fixed with separation network 13, and in this embodiment, separation network 13 is the wire net, and separation network 13's mesh is less than grid net 3's mesh, and then plays better filtering action to rivers, reduces impurity rubbish and passes through inspection shaft 2 flow direction sewer 1, and then causes sewer 1 to block up.
In addition, as shown in fig. 2 and 4, a rotating shaft 4 is transversely fixed at a manhole opening 21 of the manhole 2 along a horizontal direction, the rotating shaft 4 is arranged along a radial direction of the manhole opening 21, and two ends of the rotating shaft 4 are fixed on a wall of the manhole 2. The articulated seat of the bear of rotating 5 on the pivot 4, be fixed with the board 6 of opening and close that is used for opening and close inspection shaft mouth 21 on articulated seat 5, open and close board 6 and be circular setting, and the border circumference cladding of opening and close board 6 has elastic rubber circle and elastic rubber circle to contradict with the wall of a well of inspection shaft 2 to increase the gas tightness between the wall of a well of opening and close board 6 and inspection shaft 2, prevent that the foul smell from gushing on inspection shaft 2.
As shown in fig. 2 and 3, a vertical rod 7 is fixedly installed on the bottom surface of the grille net 3 along the vertical direction, and a collision component for colliding the edge of the opening and closing plate 6 to enable the opening and closing plate 6 to rotate around the rotating shaft 4 is arranged on the vertical rod 7. Specifically, the abutting assembly comprises a water storage barrel 9 connected to the vertical rod 7 in a sliding manner and a spring 10 sleeved on the vertical rod 7, in the embodiment, the water storage barrel 9 is of a cylindrical structure with an opening at the top, and the vertical rod 7 penetrates through the water storage barrel 9 along the central line direction of the water storage barrel 9; the bottom end of the vertical rod 7 is additionally provided with a limiting block 8, the spring 10 is sleeved between the limiting block 8 and the water storage barrel 9, one end of the spring 10 is fixedly connected with the bottom end of the water storage barrel 9, and the other end of the spring is fixedly connected with the upper surface of the limiting block 8. During drainage, water flows from the inspection well opening 21 to the water storage barrel 9, and the weight of the water storage barrel 9 is increased. As the weight of the water storage tub 9 is gradually increased, the water storage tub 9 is gradually lowered and the spring 10 is compressed. The lateral wall of water storage bucket 9 is fixed with butt pole 11 along vertical direction, and in this embodiment, butt pole 11 is followed vertical direction downwardly extending to the conflict and is opened and close the upper surface of board 6, when water storage bucket 9 descends, can drive butt pole 11 and descend and conflict downwards and open and close board 6 for it rotates to open and close board 6 revolute 4, and then makes inspection shaft mouth 21 be in the state of opening, so that the drainage.
As shown in fig. 2 and 3, in order to facilitate collecting the water flow under the condition of small water flow, a material guiding hopper is additionally arranged at the top of the water storage barrel 9, so that more water flow can be collected in the water storage barrel 9, and further, when the water flow is small, the inspection well opening 21 can be opened by abutting against the opening and closing plate 6 through the abutting rod 11. In addition, at least one drainage hole 92 is formed in the side wall of the water storage barrel 9, and the drainage hole 92 is located in the middle of the water storage barrel 9. In this embodiment, there are two drain holes 92, and the two drain holes 92 are uniformly distributed on the sidewall of the water storage barrel 9. Through addding wash port 92 so that carry out the drainage to water storage bucket 9, when the rivers that flow to water storage bucket 9 were less than the drainage rate of wash port 92, the weight of water storage bucket 9 reduced gradually, and spring 10 drives water storage bucket 9 under the effect of elasticity and rises gradually to make butt pole 11 rise, and then play the effect of the rotation angle of opening and closing board 6 through the size change of discharge.
In order to reduce the relative friction between the abutting rod 11 and the opening and closing plate 6 when the abutting rod 11 abuts against the opening and closing plate 6 downwards, the bottom end of the abutting rod 11 is set to be in arc transition, so that the abutting rod 11 can abut against the opening and closing plate 6 downwards and turn over smoothly.
In addition, as shown in fig. 2 and 4, since the opening and closing plate 6 needs to be reset after the drainage, and then the inspection well opening 21 is closed again, an elastic reset member for resetting the opening and closing plate 6 is added to the hinge base 5. Specifically, the elastic reset piece comprises a torsion spring 12 sleeved on the rotating shaft 4, one end of the torsion spring 12 is fixedly connected with the bottom surface of the opening and closing plate 6, the other end of the torsion spring is fixedly connected with the rotating shaft 4, and when the torsion spring 12 is in a natural state, the opening and closing plate 6 closes the inspection well opening 21.
The overall working process is as follows: the inspection well opening 21 is closed by additionally arranging the opening and closing plate 6, and the elastic rubber pad is additionally arranged to increase the air tightness between the opening and closing plate 6 and the wall of the inspection well 2, so that odor is blocked, and the rising of the odor is prevented, when drainage is needed, water flows to the water storage barrel 9, so that the weight of the water storage barrel 9 is changed, when the gravity of the water storage barrel 9 is greater than the upward elastic force of the spring 10, the water storage barrel 9 slides downwards to compress the spring 10, the abutting rod 11 is driven to abut against the top surface of the opening and closing plate 6 in the pressing process of the water storage barrel 9, one side of the opening and closing plate 6 is pressed to enable the opening and closing plate 6 to rotate around the rotating shaft 4; when the weight of the water storage barrel 9 is gradually reduced, the spring 10 drives the water storage barrel 9 to ascend under the action of restoring force, and the torsion spring 12 drives the opening and closing plate 6 to reset under the action of restoring force, so that the inspection well opening 21 is closed.
The above embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
