Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention is shown: a landscaping drainage system comprises a drainage well 1, a well cover 2 is arranged at the top end of the drainage well 1, a fixing ring 3 is fixedly connected to the inner wall of the drainage well 1, an anti-backflow mechanism is arranged on the inner wall of the fixing ring 3, the anti-backflow mechanism comprises a fixing frame 4, a fixing block 5, a tension spring 6, a limiting plate 7, a connecting rod 8 and a partition plate 9, the fixing frame 4 is fixedly connected with the inner wall of the fixing ring 3, the fixing block 5 is arranged in the middle of the fixing frame 4, the inner wall of the fixing block 5 is elastically connected with the limiting plate 7 through the tension spring 6, the limiting plate 7 moves relatively in the fixing block 5, the connecting rod 8 is arranged at the bottom end of the limiting plate 7, the lower end of the connecting rod 8 penetrates through the inner wall of the fixing block 5, the partition plate 9 is arranged at the bottom end of the connecting rod 8, water is accumulated on the upper surface of the partition plate 9 when being drained, and is influenced by gravity, the partition plate 9 moves downwards, and separate from fixed ring 3, make water flow downward through the baffle 9, reach the effect of the drainage, when the water in the drainage system flows back, because the density of the baffle 9 is less than the water seal, and the tension spring 6 exerts an ascending pulling force to the baffle 9 through the tie rod 8, when the water level is too high, the baffle 9 moves upwards, and close with the bottom of the fixed ring 3, make the water in the drainage system unable to continue to rise, thus reach the effect of preventing flowing back, when the drainage system does not drain, the tension spring 6 exerts an ascending pulling force to the baffle 9 through the tie rod 8, and make the baffle 9 move upwards, close with the bottom of the fixed ring 3, thus reach the effect of preventing the peculiar smell in the drainage system from floating out, improve the environmental quality of the garden.

The density of the partition 9 is less than that of water, and since the density of the partition 9 is less than that of water, in the event of failure of the tension spring 6, the water level in the drainage system rises, and the partition 9 will still rise and close with the fixed ring 3.

The bottom of solid fixed ring 3 is equipped with sealing ring 10, through the setting of sealing ring 10, when baffle 9 and solid fixed ring 3 closed, reaches the effect that increases the seal box nature between baffle 9 and the sealing ring 10.

The top of solid fixed ring 3 is equipped with filter screen 11, and the top diameter of filter screen 11 is greater than the internal diameter of solid fixed ring 3, and through the setting of filter screen 11, filter screen 11 filters the great impurity in aquatic, prevents that these great impurities from piling up in drainage system's inside to reduce drainage system's jam probability.

The middle part of filter screen 11 is equipped with handle 12, through the setting of handle 12, reaches the effect that makes things convenient for personnel to take out filter screen 11 and change or clear up it.

The working principle is as follows: when water is drained, water is accumulated on the upper surface of the partition plate 9 and is influenced by gravity, the partition plate 9 moves downwards and is separated from the fixing ring 3, so that the water flows downwards through the partition plate 9 to achieve the effect of draining, when the water in the drainage system flows back, the density of the partition plate 9 is smaller than the sealing of the water, the tension spring 6 exerts an upward tension on the partition plate 9 through the connecting rod 8, when the water level is overhigh, the partition plate 9 moves upwards and is closed with the bottom end of the fixing ring 3, so that the water in the drainage system cannot continuously rise, the effect of preventing backflow is achieved, when the drainage system does not drain, the tension spring 6 exerts an upward tension on the partition plate 9 through the connecting rod 8, the partition plate 9 moves upwards and is closed with the bottom end of the fixing ring 3, the effect of preventing peculiar smell in the drainage system from floating is achieved, the environment quality of gardens is improved, the filter screen 11 filters larger impurities in the water, prevent that these great impurities from piling up in drainage system's inside to reduce drainage system's probability of blockking up, when needing to be changed or clearance filter screen 11, open well lid 2 earlier, then take out filter screen 11 through handle 12 and clear up or change, change or clear up the completion back, place filter screen 11 on solid fixed ring 3 once more, and close well lid 2.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
