Detailed Description
The following description of the embodiments of the present invention 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 invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 and fig. 2, a building drain pipe energy reducing device comprises a shell 1 and a water inlet 2 and a water outlet 3 which are respectively arranged at the upper part and the lower part of the shell 1, wherein a first energy reducing mechanism and a second energy reducing mechanism are respectively arranged in the shell 1, the upper end and the lower end of the first energy reducing mechanism are respectively corresponding to the water inlet 2 and the water outlet 3, the second energy reducing mechanism is communicated with the first energy reducing mechanism, and the tail end of the second energy reducing mechanism and the tail end of the first energy reducing mechanism are correspondingly arranged to be energy reducing structures.
When in use, the energy reducing device is arranged on the drainage pipe of the building at intervals, such as every ten meters. The water inlet 2 is connected with the bottom of the previous section of drain pipe, the water outlet 3 is connected with the top of the next section of drain pipe, in practice, the water inlet 2 and the water outlet 3 are respectively provided with a connecting piece, the connecting piece is a thread in the embodiment, and other existing drain pipe connecting structures can be adopted in other embodiments. After rainwater enters the first energy reduction mechanism from the water inlet 2, part of rainwater is subjected to energy reduction treatment by the first energy reduction mechanism, and part of rainwater enters the second energy reduction mechanism due to the communication between the second energy reduction mechanism and the first energy reduction mechanism, the second energy reduction mechanism is used for energy reduction treatment of potential energy, and rainwater discharged from the first energy reduction mechanism and the second energy reduction mechanism is subjected to energy reduction treatment once through the energy reduction mechanism. After the multistage energy reduction treatment, the potential energy of falling rainwater is greatly reduced, and the energy reduction effect is good. The device is of a fixed mechanical structure, operation faults of the device cannot occur, maintenance is not needed, and the device is simple in structure and convenient to use.
Specifically, the first energy reducing mechanism comprises a cylinder 4 and a first energy reducing piece arranged in the cylinder 4, the top of the cylinder 4 is communicated with the water inlet 2, and the lower part of the cylinder 4 is arranged corresponding to the water outlet 3; communication holes 7 are uniformly distributed on the side wall of the cylinder 4 corresponding to the second energy reducing mechanisms, and a ring cavity is arranged between the outer side wall of the cylinder 4 and the inner side wall of the shell 1. The bottom of the ring cavity is provided with an opening and is arranged corresponding to the water outlet 3. The second energy reduction mechanism comprises a second energy reduction piece, and the second energy reduction piece is arranged in the annular cavity between the inner side wall of the shell and the first energy reduction mechanism. The first energy reduction piece and the second energy reduction piece are respectively of gradual change structures gradually increasing according to energy reduction capacity, rainwater enters the cylinder body 4 from the water inlet 2, is discharged from the bottom of the cylinder body 4 to the water outlet 3 after energy reduction treatment by the first energy reduction piece, part of rainwater enters the annular cavity through the communication hole 7 when the rainwater is in the cylinder body 4, and is discharged from the bottom of the annular cavity to the water outlet 3 after energy reduction treatment by the second energy reduction piece. The gradual change type structure of the first energy reduction piece enables the energy reduction capacity of the upper portion of the first energy reduction piece to be weak, but impact force born by the first energy reduction piece when falling rainwater is received is relatively small, and gradual change strengthening weakening is carried out on contacted rainwater potential energy along with improvement of the energy reduction capacity of the gradual change type structure of the first energy reduction piece. Similarly, the gradual change structure of the second energy reducing member makes the energy reducing capability of the upper part of the second energy reducing member weak, but the impact force born by the second energy reducing member is relatively smaller when receiving the rainwater with larger potential energy entering from the upper part of the first energy reducing mechanism, and the contacted rainwater potential energy is weakened gradually and strengthened along with the improvement of the energy reducing capability of the gradual change structure of the second energy reducing member.
In this embodiment, the first energy reducing member is a forward spiral plate 5, and the pitch of the forward spiral plate 5 is gradually reduced. The second energy reducing member is a reverse spiral plate 6, and the pitch of the reverse spiral plate 6 is gradually reduced. After the rainwater enters the cylinder body 4 from the water inlet 2, the rainwater firstly contacts the upper part of the forward spiral plate 5, and the impact force between the rainwater and the upper part of the forward spiral plate 5 is relatively smaller because the screw pitch and the inclination of the upper part of the forward spiral plate 5 are large, so that the forward spiral plate 5 is protected. Under the action of the forward spiral plate 5, rainwater spirally flows in the cylinder 4, and the vertical falling speed of the rainwater is converted into the inclined falling speed, so that the falling speed of the rainwater is reduced, namely the falling potential energy of the rainwater is reduced. As the pitch of the forward spiral plate 5 is reduced, the inclination angle of the forward spiral plate 5 is gradually reduced, so that the vertical downward velocity component of the rainwater is further reduced, thereby gradually enhancing the falling potential energy weakening effect of the rainwater. Meanwhile, when rainwater flows spirally in the cylinder body 4, part of rainwater enters the annular cavity from the communication hole 7 due to the centrifugal effect, and the second energy reduction piece in the annular cavity is the reverse spiral plate 6, so that the speed direction of the rainwater entering the annular cavity has a certain interference effect with the reverse spiral plate 6 and the direction of the rainwater flowing on the reverse spiral plate 6, and a certain attenuation effect on the rainwater potential energy between the first energy reduction mechanism and the second energy reduction mechanism is achieved. The reverse spiral plate 6 itself has a similar energy-reducing effect to the forward spiral plate 5.
In this embodiment, the width of the forward spiral plate 5 is the radius length of the cylinder 4, the width of the ring cavity and the width of the reverse spiral plate 6 are also the radius length of the cylinder 4, the diameter of the cylinder 4 is equal to two thirds of the diameter or the diameter of the drain pipe, the inclination of the plate of the upper spiral circle of the forward spiral plate 5 is 30 degrees with the vertical direction, the inclination of the plate at the outlet of the bottom of the forward spiral plate 5 is 70 degrees to 80 degrees with the vertical direction, and the inclination of the plate of the reverse spiral plate 6 from top to bottom is gradually changed from 45 degrees to 70 degrees to 80 degrees with the vertical direction. Preferably, in order to further protect the upper portion of the forward spiral plate 5, the frequency of maintenance or replacement is reduced as much as possible, and the upper surface of the first energy reducing member is provided with a buffer gasket, in practice a rubber gasket, which plays a role in buffering and protecting the upper surface of the forward spiral plate 5. In this embodiment, the communication hole 7 is a bar-shaped hole along the spiral direction.
Preferably, the end water outlet of the first energy reduction mechanism and the end water outlet of the second energy reduction mechanism are correspondingly arranged, and the water outlet structures with opposite water outlet directions are mutually abutted to form the energy reduction structure. That is, the water outlet end of the forward spiral plate 5 and the water outlet end of the reverse spiral plate 6 are correspondingly arranged, so that the water flushed from the forward spiral plate 5 and the water flushed from the reverse spiral plate 6 are converged together, and the water flushed from the forward spiral plate 5 and the water flushed from the reverse spiral plate 6 are opposite in direction due to the opposite spiral directions of the forward spiral plate 5 and the reverse spiral plate 6, and when the two water are converged, a part of energy can be offset again, so that the potential energy of rainwater is further weakened.
It will be evident to those skilled in the art that the invention 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 characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention 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. Any reference sign in a claim should not be construed as limiting the claim concerned.
