Abstract
The utility model discloses a sponge city rainwater well prevents flowing backward mechanism has solved the technical problem that current rainwater well can not prevent sewage and flow backward. The utility model discloses a crimping is combed at the rainwater between the well lid and the wall of a well, the diapire that the rainwater was combed is the filter screen, and the below of filter screen is connected with a drainage section of thick bamboo, is provided with the axis of rotation on the inner wall of a drainage section of thick bamboo, is provided with the adjustable fender to the movable shutoff of a drainage section of thick bamboo activity in the axis of rotation, is provided with the waterproof rope of elasticity that links to each other with adjustable fender on the rainwater is. The utility model discloses can enough carry out the drainage to the sewer under normal conditions, can carry out automatic shutoff under the circumstances that the sewer blocks or gushes water again, and then prevent that the interior sewage of sewer from flowing backward and gushing outward, guarantee that the environment on the ground does not receive the pollution.
Description
Technical Field
The utility model relates to a rainwater well technical field especially indicates a sponge city rainwater well prevents flowing backward mechanism.
Background
The sewer is a public facility in cities, and the device has appeared as early as the ancient Roman period. The rudimentary form of sewer originated in paris, france, which to date has the largest urban sewer system in the world. Generally, a sewage system is used for collecting and discharging domestic wastewater generated in cities and industrial wastewater generated in industrial production. The sewer is good for modern cities, and the sponge city is proposed to solve the problem of urban drainage. Various waste water on the ground enters the sewer through the water outlet, wherein a catch basin is the most common inlet of the sewer. The existing catch basin has single function and can only play a role in drainage, when rainwater is too large or a sewer is blocked, the drainage function is lost, even sewage in the sewer can flow back to the ground, and the environment is seriously influenced.
SUMMERY OF THE UTILITY MODEL
To not enough among the above-mentioned background art, the utility model provides a sponge city rainwater well prevents flowing backward mechanism has solved current rainwater well and can not prevent the technical problem that sewage flows backward.
The technical scheme of the utility model is realized like this: the utility model provides a sponge city rainwater well prevents flowing backward mechanism, includes that the crimping is combed at the rainwater between the well lid and the wall of a well, the diapire that the rainwater was combed is the filter screen, and the below of filter screen is connected with a drainage section of thick bamboo, is provided with the axis of rotation on the inner wall of a drainage section of thick bamboo, is provided with the adjustable fender to the movable shutoff of a drainage section of thick bamboo activity in the axis of rotation, is provided with the waterproof rope of elasticity that links to each other with the.
Further, the drainage cylinder is in a horn shape with two small ports butted with each other, the reverse reducing part of the drainage cylinder is fixedly arranged on the rotating shaft, and the radius of the movable baffle is larger than that of the reverse reducing part of the drainage cylinder.
Furthermore, the inner wall of the drainage tube is provided with a stop block, the stop block is arranged below the movable baffle plate, and an included angle between the movable baffle plate and a horizontal plane when the movable baffle plate is arranged above the stop block is smaller than 45 degrees.
Furthermore, when the movable baffle is arranged above the stop block, the included angle between the movable baffle and the horizontal plane is 30 degrees.
The utility model discloses can enough carry out the drainage to the sewer under normal conditions, can carry out automatic shutoff under the circumstances that the sewer blocks or gushes water again, and then prevent that the interior sewage of sewer from flowing backward and gushing outward, guarantee that the environment on the ground does not receive the pollution. The utility model discloses the waterproof rope of elasticity that sets up can carry out the shutoff to adjustable fender under the condition of no rainwater downflow, prevents sewer peculiar smell diffusion to a certain extent, can push down adjustable fender after having the rainwater to flow again, has the automatic function of finishing of opening. The utility model discloses the dog that sets up can prevent effectively that the waterproof rope of elasticity from becoming invalid and the malfunction that causes. Even the waterproof rope of elasticity became invalid or the fracture back, the dog can carry on spacingly to adjustable fender, when the sewer takes place to block or gush water, the sewage of lower part can be with adjustable fender jack-up, and then has prevented effectively that sewage from flowing backward and gushing outward.
Drawings
In order to illustrate the embodiments of the present invention more clearly, the drawings that are needed in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the description below are only some embodiments of the present invention, and that other drawings can be obtained by those skilled in the art without inventive work.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
The lower part of the filter screen 9 is connected with a drainage tube 4, the inner wall of the drainage tube 4 is provided with a rotating shaft 5, the rotating shaft 5 is provided with a movable baffle 6 for movably plugging the drainage tube 4, and the movable baffle 6 can control the on-off of the drainage tube 4. The rainwater comb 3 is provided with an elastic waterproof rope 8 connected with the movable baffle 6, and when no rainwater flows into the upper part of the movable baffle 6, the movable baffle 6 is in the blocking position of the drainage tube 4 under the action of the elastic waterproof rope 8. When rainwater flows to the upper part of the movable baffle 6 and accumulates to a certain weight, the movable baffle 6 is pressed downwards, and then the drainage tube 4 is opened, and the rainwater can flow into a sewer below.
The other structure of this embodiment is the same as embodiment 1.
When the movable baffle 6 is erected above the stop block 7, the included angle between the movable baffle 6 and the horizontal plane is smaller than 45 degrees, and the smaller the included angle between the movable baffle 6 and the horizontal plane is, the quicker and more reliable the movable baffle 6 is jacked when a sewer is blocked or gushes water.
Further, when the movable baffle 6 is erected above the stop block, the included angle between the movable baffle 6 and the horizontal plane is 30 degrees.
The other structure of this embodiment is the same as embodiment 1 or 2.
The present invention is not exhaustive and is well known to those skilled in the art.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
