Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a sewage interception well. Background Art

[0002] A sewage interception well is a sewage interception well specially used in urban combined sewer systems. It is generally set up at the confluence of rainwater pipes and sewage pipes. The function of the sewage interception well is to prevent sewage from being discharged directly into rivers and lakes. The intercepted sewage can be led to the sewage network or sewage treatment plant for reprocessing, thereby avoiding water pollution. It is an essential facility for the end-of-pipe treatment technology of non-point source pollution.

[0003] The patent document with the authorization announcement number CN 220666414 U discloses a sewage interception well, including a water collection well with a water inlet pipe, a water pump and a differential pressure level meter arranged in the water collection well, the water pump is connected to the output pipe, an overflow retaining wall is arranged in the water collection well, the top of the overflow retaining wall is lower than the top of the water collection well, the overflow retaining wall divides the water collection well into a left chamber and a right chamber, the water pump and the differential pressure level meter are located in the right chamber, and the left chamber is connected to the overflow drainage pipe. During normal operation, rainwater enters the water collection well and reaches the upper water level, the differential pressure level meter is powered, the water pump starts, and the output pipe drains water outward; when the water level drops to the lower water level, the water pump stops. In case of heavy rain, the water pumping amount is less than the amount of rainwater, the differential pressure level meter senses the super-high water level, and the rainwater overflows from the overflow retaining wall. At the same time, the water pump stops, enters sleep, and drains water intermittently until the differential pressure level meter senses the lower water level. The main structure of the sewage interception well is a water collection well, which is cast in situ by concrete and is not suitable for mass production. Utility Model Content

[0004] The technical problem solved by the utility model is that the sewage interception well in the prior art is formed by pouring concrete in situ and is not suitable for mass production.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: the structure of the intelligent sewage interception well includes a submersible pump, a liquid level sensor, and a liquid level retaining wall. The submersible pump, the liquid level sensor, and the liquid level retaining wall are installed in a barrel body. The barrel body is provided with a rainwater inlet flange, a rainwater outlet flange and a sewage outlet pipe. The liquid level retaining wall is located between the submersible pump and the rainwater outlet flange. The sewage outlet pipe is connected to the submersible pump. The outlet end of the sewage outlet pipe extends out of the barrel body and is provided with a connecting flange. A cover plate is provided on the top of the barrel body.

[0006] Different from the prior art, the barrel of the utility model is made of glass fiber reinforced plastics, which can be mass-produced, saving the production cost of the sewage interception well. Moreover, the sewage interception well of the utility model can be transported to the installation site for on-site installation, and the rainwater inlet flange, rainwater outlet flange and sewage outlet pipe connection flange of the barrel can be connected to the corresponding pipelines at the installation site, which provides convenience for the installation of the sewage interception well.

[0007] The bottom of the barrel body is provided with a base, which is in a downwardly flared shape, and the outer wall of the base is provided with a base reinforcement rib, so that the barrel body can stand stably.

[0008] A vertical grille plug-in interface is provided on the inner wall of the barrel, a grille is inserted into the grille plug-in interface, the grille is located between the rainwater inlet flange and the submersible pump, and a grille handle is provided on the top of the grille. By opening the cover, workers can place or remove the grille from the top of the barrel, and the grille can be easily replaced.

[0009] A vertical retaining wall plug-in interface is arranged on the inner side wall of the barrel body, and the liquid level retaining wall is plugged into the retaining wall plug-in interface. A retaining wall handle is arranged on the top of the liquid level retaining wall. By opening the cover plate, workers can place or take out the liquid level retaining wall from the top of the barrel body, and the liquid level retaining wall is easy to install.

[0010] A sensor wire pipeline is arranged on the side wall of the barrel body, the wire of the liquid level sensor is inserted into the sensor wire pipeline, and the liquid level sensor is electrically connected to the single chip computer through the wire.

[0011] The submersible pump comprises a first submersible pump and a second submersible pump, and the first submersible pump and the second submersible pump are respectively connected to the sewage outlet pipe through a submersible pump outlet pipe. The single chip microcomputer can start and stop the first submersible pump and the second submersible pump through wireless communication.

[0012] When water enters the rainwater inlet flange, the grille blocks the garbage in the water, and the water flows through the grille. The water level in the barrel rises, and the liquid level sensor (a total of four gears) closes in the first gear, and the water level continues to rise. The second gear is closed. When the water level rises to the third gear, the first submersible pump starts to work, and the second submersible pump does not work. The sewage passes through the submersible pump outlet pipe and is pumped into the sewage outlet pipe, and finally concentrated into the municipal sewage network. After the first submersible pump works, the water level in the barrel drops. When the liquid level sensor is disconnected in the first gear, the first submersible pump stops working. When the water level in the barrel rises again, the first submersible pump starts to work in a cycle. The running time of the first and second submersible pumps is calculated based on the initial power-on, and they are exchanged every eight hours. For example, the single chip microcomputer uses the time when the first submersible pump is first powered on as the starting point for timing. After eight hours, the first submersible pump stops and the second submersible pump is powered on. The single chip microcomputer uses the time when the second submersible pump is powered on as the starting point for timing. After eight hours, the second submersible pump stops and the first submersible pump is powered on. In this way, the first submersible pump and the second submersible pump alternately operate every eight hours.

[0013] When it is rainy season, the water level in the barrel rises rapidly. When the water volume of the first submersible pump is less than the water volume in the rainy season, the fourth gear of the liquid level sensor is closed (high liquid level), and the first submersible pump is started for 20 minutes every hour. If the first submersible pump fails to pump the liquid level sensor to disconnect the first gear after starting for 20 minutes, the first submersible pump will continue to be started for 20 minutes every hour until the liquid level sensor can be disconnected and the normal water level working state is restored. When the fourth gear of the liquid level sensor is closed, a fault is reported, which is a high liquid level fault. If the overload protection of the first submersible pump / second submersible pump is triggered, the fault is reported, which is a submersible pump fault.

[0014] During the rainy season, the amount of rainwater is much greater than the pumping capacity of the first submersible pump, and the rainwater can overflow the liquid level retaining wall and be discharged through the rainwater outlet flange.

[0015] The single-chip microcomputer is set in the intelligent control cabinet, which is located on the ground. A 4G suction cup antenna is set on the top of the intelligent control cabinet, and the 4G suction cup antenna is connected to the single-chip microcomputer. The remote control terminal can be wirelessly connected to the single-chip microcomputer to remotely shut down or start any submersible pump. When encountering a high liquid level, the single-chip microcomputer transmits an alarm message to the remote control terminal by wireless means.

[0016] The cover plate includes a cover plate frame and a cover plate body matched in the cover plate frame. The cover plate body includes a cover plate shell and a disc-shaped cast iron matched in the cover plate shell. A triangular structure is provided on the inner wall of the cover plate shell. A hook groove is provided on the triangular structure. A triangular structure giving way is provided on the edge of the disc-shaped cast iron. Workers can lift the cover plate body by inserting an iron hook into the hook groove to open the sewage interception well.

[0017] The outer wall of the cover frame is provided with a frame reinforcement rib, and the edge of the cover frame is provided with a plurality of arc-shaped fixing holes, which are distributed along the circumference of the cover frame, and an arc-shaped fixing hole is provided between each two adjacent frame reinforcement ribs. The barrel body is buried in a pit below the ground, the top surface of the cover frame is flush with the ground, the top surface of the cover body is flush with the top surface of the cover frame, and the edge of the cover frame is sunken in the concrete of the ground. The arc-shaped fixing holes can make the edge of the cover frame firmly combined with the ground.

[0018] A partition positioning step is provided on the top of the barrel body, and an anti-fall net partition is provided on the partition positioning step. The anti-fall net partition is located below the cover. When the cover is opened, the anti-fall net partition can prevent pedestrians from falling into the barrel body, which is beneficial to the safety of pedestrians.

[0019] The utility model has two submersible pumps, one for use and one for backup, which are used in rotation at regular intervals. Any submersible pump is equipped with phase loss protection, overload protection, liquid level lower limit soft protection, and drainage timeout protection. Through the 4G Internet of Things function, remote control operation of the sewage interception well, adjustment of setting parameters, timely reporting of fault information, and shielding and shutting down the submersible pump can be realized. In automatic mode, the submersible pump can be automatically started and stopped according to the set water level parameters. BRIEF DESCRIPTION OF THE DRAWINGS
