The device comprises a substrate and a cover plate, wherein the left side and the right side of an inner cavity of the substrate are symmetrically provided with rotating shafts, the inner cavity of the substrate is rotatably provided with sealing plates through the rotating shafts, the sealing plates are of semicircular structures, and floating blocks are arranged at the bottom positions of the sealing plates, which are close to one side of each other. Not only ensures normal drainage, but also can avoid the countercurrent of rainwater.
Description
Technical Field
The utility model relates to the technical field of well covers, in particular to an anti-backflow well cover.
Background
In order to avoid falling of personnel, vehicles or articles, a large number of well covers are required in municipal drainage networks.
The prior art has the following publication numbers: a water supply and drainage well cover of CN202324005U comprising: an annular well seat; the well cover is arranged above the annular well seat and is in threaded connection with the annular well seat, and the well cover is of at least two layers of structures, wherein reinforcing ribs are arranged in each layer of structure; the waterproof well cover is arranged between the well cover and the annular well seat.
When the well lid is used, and the rainwater quantity is larger, the water quantity exceeds the maximum bearing capacity of the sewer, so that the danger is caused by countercurrent jacking of the well lid by rainwater in the sewer.
Disclosure of Invention
(one) solving the technical problems
In order to solve the problems in the prior art, the utility model provides the anti-backflow well cover, which can effectively avoid danger caused by rainwater backflow.
(II) technical scheme
In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps:
the utility model provides an anti-reflux well lid, includes base member and apron, the axis of rotation is installed to base member inner chamber left and right sides symmetry, the base member inner chamber is installed through the axis of rotation and is installed the closing plate, the closing plate is semicircle structure, the closing plate is close to one side bottom position each other and is provided with the kicking block. Not only ensures normal drainage, but also can avoid the countercurrent of rainwater.
Preferably, a limiting ring is arranged on the inner wall of the substrate and positioned at the lower part of the rotating shaft.
Preferably, the cover plate is provided with a water discharging groove.
(III) beneficial effects
The utility model provides an anti-backflow well cover. The beneficial effects are as follows:
(1) When the rainwater flows down, the sealing plate is in an automatic opening state, normal water flowing is guaranteed, and when the rainwater flows back, the sealing plate is automatically closed, so that the rainwater is prevented from flowing back to prop up the cover plate.
(2) The equipment has simple structure and lower manufacturing cost and use cost.
Drawings
FIG. 1 is a block diagram of the present utility model;
FIG. 2 is a diagram of the structure of the lumen of the matrix of the present utility model.
In the figure: 1. a base; 2. a cover plate; 3. a rotating shaft; 4. a sealing plate; 5. a floating block; 6. a limiting ring; 7. and a water discharging groove.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, the anti-backflow well lid of the embodiment comprises a base body 1 and a cover plate 2, wherein the left side and the right side of an inner cavity of the base body 1 are symmetrically provided with rotating shafts 3, the inner cavity of the base body 1 is rotatably provided with sealing plates 4 through the rotating shafts 3, the sealing plates 4 are of semicircular structures, and floating blocks 5 are arranged at the positions, close to the bottom of one side, of the sealing plates 4. Under normal condition, closing plate 4 receives self gravity and the gravity of kicking block 5, and closing plate 4 bit upset open condition, when taking place to flow backward, receives the buoyancy of kicking block 5, and closing plate 4 is in the closed condition, avoids flowing backward.
Further, a limit ring 6 is arranged on the inner wall of the base body 1 and positioned at the lower part of the rotating shaft 3. Avoid closing plate 4 upset excessively, guarantee closing plate 4 to be in the horizontality, guarantee the seal to the inner chamber of base member 1.
Further, the cover plate 2 is provided with a water drain tank 7.
Working principle: when the water is discharged, the sealing plate 4 receives the gravity of the self, the gravity of the floating block 5 and the impact force of water, the sealing plate 4 turns over to be in an open state, if countercurrent occurs, one side of the sealing plate 4, which is close to each other, is subjected to the buoyancy of the floating block 5 and the upward impact force of the water flow, one side of the sealing plate 4, which is close to each other, is jacked up upwards, is subjected to the action of the limiting ring 6, and the sealing plate 4 is in a horizontal sealing state, so that countercurrent is avoided.
