Background

According to related data, most rural areas in China are relatively clean in rainwater, but runoffs formed after the rainfall are relatively dirty, mainly because more sediment exists on village roads, meanwhile, excrement is cultivated on the periphery, if a rainwater collection system is not completed, the runoffs formed by the rainfall are directly discharged into adjacent river channels through the village roads, and water environment is easily damaged. Therefore, the initial rainwater needs to be treated. At present, an intercepting well system is generally adopted to intercept primary rain to a sewage pipeline, the sewage pipeline is sent to a sewage treatment plant for purification treatment, and the rain water pollution degree in the later period of rainfall is light, so that the rain water can be directly discharged into natural water without entering the sewage pipeline.

The intercepting well systems are of various types and mainly comprise power equipment and unpowered equipment. The main well of the intercepting well with the power equipment is internally provided with a lifting pump or an electric control valve, and the water inflow is controlled by starting and stopping the water pump or the electric control valve, so that the functions of collecting sewage in dry seasons and collecting initial rainwater and sewage in rainy seasons are realized; compared with the intercepting well with power equipment, the unpowered intercepting well has obvious advantages in the aspects of overall manufacturing cost and engineering operation and maintenance, and is more suitable for being used in areas with imperfect infrastructure, such as villages and towns and the like and rare manpower.

Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

As shown in fig. 1 and 2, the simple unpowered intercepting well comprises an intercepting well body 1 arranged beside a drainage channel, and a sewage intercepting pipe 2 is arranged between the drainage channel and the intercepting well body 1 in a communicating manner. Specifically, one end of the sewage interception pipe 2 is communicated with the top of the side wall of the intercepting well body 1, and the other end is communicated with the bottom of the side wall of the drainage channel. For example, the drainage channel may be an existing open drainage channel. A slag blocking grid 3 is also arranged at the joint of the drainage canal and the sewage interception pipe 2.

Therefore, sewage interception can be carried out through the sewage interception pipe 2 and the slag blocking grid 3 in dry seasons and early rainfall periods; when in heavy rain, the rainwater can be normally discharged through the current drainage channel, and the flood drainage function of the channel is not affected.

In some embodiments, a flow blocking plate 4 is disposed at the rear end of the sewage interception tube 2 in the drainage channel, that is, along the direction of the water flow, the water flow will flow through the sewage interception tube 2 and then abut against the flow blocking plate 4. In addition, a blocking plate 5 is rotatably arranged at the side wall of the drainage channel. For example, the baffle 4 can slide along the drainage channel under the impact of water flow, and the baffle 4 can rotate under the impact of water flow after moving to the maximum stroke. Correspondingly, a transmission assembly 6 is connected between the plugging plate 5 and the flow baffle 4. During the movement of the baffle plate 4, the transmission assembly 6 can drive the plugging plate 5 to rotate.

For example, in dry seasons and early rainfall, the impact force of water flow is small, and the water flow can flow through the sewage interception pipe 2 and be directly discharged into the intercepting well body 1; in the case of heavy rain, the water flow in the early period of rainfall still performs the above action and is discharged into the intercepting well body 1. With the increase of the impact force of the water flow, the water flow can push the flow baffle plate 4 to slide; at this time, the transmission component 6 drives the plugging plate 5 to close the sewage interception pipe 2, and the flow blocking plate 4 slides to the maximum sliding distance; then, the impact force of the water flow on the flow baffle plate 4 is continuously increased, so that the flow baffle plate 4 is driven to rotate, and the water flow in the later period of rainfall can normally discharge flood through the drainage channel.

In addition, the end of the intercepting well body 1 is also provided with a flow-limiting baffle 12. For example, in rural areas, the caliber of the sewage pipeline is smaller, and the filling speed of the sewage pipeline can be faster than the closing speed of the baffle, so that the flow limiting baffle 12 is arranged at the tail end of the intercepting well body 1, the overmuch filling degree of the sewage pipeline can be avoided, and the service life of the sewage pipeline can be prolonged.

For example, the transmission assembly 6 may include a rack 7 disposed on the baffle plate 4 and a first gear 8 sleeved on the rotation shaft of the blocking plate 5, and a second gear 9 is meshed between the rack 7 and the first gear 8. Thus, along with the sliding of the baffle plate 4, the rack 7 drives the second gear 9 to rotate, and the second gear 9 drives the first gear 8 to drive the plugging plate 5 to rotate. It will be appreciated that the second gear 9 will act as a reversing drive, allowing the plugging plate 5 to be rotated as desired to the side of the dirt trap 2.

More specifically, a slide rail and a slider may be provided on the side wall of the drain passage in the water flow direction, and the flow blocking plate 4 may be mounted on the slider, whereby the sliding of the flow blocking plate 4 in the drain passage may be achieved. For example, the baffle 4 is rotatably disposed on the slider, and a torsion spring (not shown) is further connected to the rotation shaft of the baffle 4.

Therefore, under the impact of water flow, the baffle plate 4 has the sliding freedom degree, so that the baffle plate 4 slides in the matching of the sliding block and the sliding rail; when the baffle 4 slides to the maximum sliding distance, for example, when the blocking plate 5 completely closes the dirt blocking pipe 2, the sliding freedom degree of the baffle 4 is limited, and then the water flow impacts the baffle 4 to drive the torsion spring to deform, so that the baffle 4 rotates for normal passing of the water flow.

In some embodiments, the baffle plate 4 is further connected with an elastic member 11. Preferably, the elastic member 11 may be connected between the slider and the slide rail. With the impact of the water flow, the sliding block moves, and the elastic piece 11 enters a deformed state. It will be appreciated that with the cessation of rain, the resilient member 11 may return to its natural state, thereby urging the deflector 4 to slide again towards the front end of the drainage channel and return to its original position as required for the interception of the initial rain at the next rainfall. For example, the elastic member 11 may be a spring.

In addition, a plurality of blocking rods 10 can be arranged on the side wall of the blocking plate 5, and the blocking rods 10 are in one-to-one correspondence with the meshes of the slag blocking grid 3. Thus, with the plugging plate 5 plugging the sewage interception pipe 2, the plugging rod 10 is inserted into the mesh, thereby removing impurities attached in the mesh. That is, the slag blocking grid 3 is not easy to be blocked.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
