Abstract
Description
Technical Field
[0001] The present application relates to the field of urban drainage technology, and in particular to a drainage structure for an underground sewage pool. Background Art
[0002] When sewage enters the sewage pool, the suspended matter will naturally settle, such as through sand retaining plates, to reduce large particles and discharge them into the next process link, thereby achieving the purpose of removing suspended solids. The sewage pool can remove suspended matter and impurities in sewage through preliminary sedimentation, which helps the smooth progress of subsequent treatment processes.
[0003] With the acceleration of urbanization, underground sewage pools, as an important part of the urban drainage system, have a direct impact on the normal operation of the system due to their drainage efficiency. Traditional underground sewage pool drainage structures often have problems such as poor drainage and easy blockage, which causes sewage to stay in the pool for too long, which not only affects the water quality, but may also cause pollution to the surrounding environment.
[0004] Therefore, it is particularly important to develop an efficient and reliable underground sewage pool drainage structure.
[0005] To this end, the present application proposes a drainage structure for an underground sewage pool. Utility Model Content
[0006] The present application proposes a drainage structure for an underground sewage pool to solve the problems raised in the above-mentioned background technology; by setting up a sedimentation area and a filtration area, preliminary sedimentation and deep filtration of sewage are achieved, effectively improving the sewage discharge efficiency. The introduction of a cleaning device solves the problem that traditional drainage structures are prone to clogging, improves the reliability and service life of the drainage structure, and greatly enhances the practicality of the device.
[0007] In order to achieve the above objectives, this application adopts the following technical solutions:
[0008] A drainage structure for an underground sewage pool includes a sewage pool, which is composed of a sewage inlet, a sedimentation area, a filtration area and a drainage pipe. The sewage inlet is arranged at the top of the sewage pool, and a sedimentation area is arranged inside the sewage pool and below the sewage inlet. The bottom of the sedimentation area adopts an inclined design, and a sediment discharge is opened inside the sewage pool and at a low point at the bottom of the sedimentation area. A drainage pipe is fixedly connected below the filtration area.
[0009] As a preferred embodiment, a filtration zone is provided inside the sewage pool and below the sedimentation zone, and the filtration zone uses four layers of filter media, namely gravel, coarse sand, medium sand and activated carbon;
[0010] Sewage enters the filtration area and is filtered through multiple layers of filter media to further remove suspended solids and small particle impurities, thereby improving the practicality of the device.
[0011] As a preferred embodiment, the crushed stone, coarse sand, medium sand and activated carbon are arranged from top to bottom, and the filter pore size decreases from large to small;
[0012] The filtration area uses four layers of filter media, namely gravel, coarse sand, medium sand and activated carbon, with each layer being 0.4 meters thick, thereby improving the practicality of the device.
[0013] As a preferred embodiment, a sewage outlet is provided inside the sewage pool, and the sewage outlet is located in the filtration area;
[0014] The sewage inlet adopts a circular structure with a diameter of 1 meter and is made of stainless steel, which improves the practicality of the device.
[0015] As a preferred embodiment, a cleaning device is provided inside the sewage pool and below the filtration area, and the cleaning device includes an electric push rod, a U-shaped frame, a rotating shaft, a motor, a quarter main gear, a slave gear, a fixing block, a high-pressure water gun and a long nozzle;
[0016] The introduction of the cleaning device solves the problem of easy clogging of the traditional drainage structure, improves the reliability and service life of the drainage structure, and thus enhances the practicality of the device.
[0017] As a preferred embodiment, the electric push rod is fixedly connected to the sewage tank, the telescopic end of the electric push rod is located inside the sewage tank and is fixedly connected to a U-shaped frame, and the interior of the U-shaped frame is rotatably connected to a rotating shaft;
[0018] By starting the electric push rod, the U-shaped frame is driven to move back and forth below the filter area in the sewage pool. As the multi-layer filter media moves from top to bottom and the pore size changes from large to small, the high-pressure water gun sprays from bottom to top, which can better clean out the impurities in the multi-layer filter media, thereby improving the practicality of the device.
[0019] As a preferred embodiment, a motor is fixedly connected to the interior of the U-shaped frame, an output end of the motor is fixedly connected to a quarter main gear, one end of the rotating shaft is fixedly connected to a slave gear, and the slave gear is meshed with the quarter main gear;
[0020] By starting the motor, the quarter main gear is driven to rotate, and the quarter main gear is engaged with the slave gear to cause the rotating shaft to rotate. When the rotating shaft rotates, it will drive the high-pressure water gun to rotate 90 degrees through the fixed block connected to it, thereby improving the practicality of the device.
[0021] As a preferred embodiment, the outside of the rotating shaft is fixedly connected to a fixed block, the inside of the fixed block is fixedly connected to a high-pressure water gun, and the high-pressure water gun is fixedly connected to a long nozzle;
[0022] By arranging a long nozzle on the high-pressure water gun, the high-pressure water flow can be sprayed onto the multi-layer filter medium in an all-round manner. As a result, the high-pressure water gun can not only sweep back and forth but also rotate and sweep, achieving a better cleaning effect, thereby improving the practicality of the device.
[0023] Beneficial effects of this application:
[0024] 1. This underground sewage pool drainage structure, by setting up a sedimentation zone and a filtration zone, achieves preliminary sedimentation and deep filtration of sewage, effectively improving sewage discharge efficiency. The introduction of a cleaning device solves the problem of easy clogging of traditional drainage structures, improves the reliability and service life of the drainage structure, and greatly enhances the practicality of the device.
[0025] 2. This drainage structure of an underground sewage pool drives the U-shaped frame to move back and forth below the filter area in the sewage pool by starting the electric push rod. At the same time, the starting motor drives the quarter main gear to engage with the slave gear to cause the rotating shaft to rotate, and drives the fixed block connected thereto to drive the high-pressure water gun to rotate ninety degrees. When the quarter main gear loses engagement with the slave gear, the high-pressure water gun is prompted to rotate under the action of high pressure, so that the high-pressure water gun can rotate ninety degrees back and forth. The long nozzle can make the ejected high-pressure water flow spray onto the multi-layer filter medium in all directions, so that the high-pressure water gun can not only sweep back and forth but also rotate and sweep to achieve better cleaning effect. Since the multi-layer filter medium is from top to bottom and the aperture changes from large to small, the high-pressure water gun can spray from bottom to top, so that impurities in the multi-layer filter medium can be better cleaned out of the multi-layer filter medium, greatly improving the practicality of the device.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0032] Reference Figure 1-3 A drainage structure of an underground sewage pool includes a sewage pool 1, which is composed of a sewage inlet 2, a sedimentation area 3, a filtration area 4 and a drainage pipe 5. The sewage inlet 2 is arranged at the top of the sewage pool 1, and a sedimentation area 3 is arranged inside the sewage pool 1 and below the sewage inlet 2. The bottom of the sedimentation area 3 adopts an inclined design, and a sediment discharge 31 is opened inside the sewage pool 1 and at a low point at the bottom of the sedimentation area 3. A drainage pipe 5 is fixedly connected below the filtration area 4.
[0033] Reference Figure 1-3 A filter area 4 is provided inside the sewage pool 1 and below the sedimentation area 3. The filter area 4 uses four layers of filter media, namely gravel 41, coarse sand 42, medium sand 43 and activated carbon 44. Sewage enters the filter area 4 and is filtered by the multi-layer filter media to further remove suspended matter and small particle impurities, thereby improving the practicality of the device.
[0034] Reference Figure 1-3 , crushed stone 41, coarse sand 42, medium sand 43 and activated carbon 44 are arranged from top to bottom, and the filter aperture changes from large to small; four layers of filter media are used in the filter area 4, namely crushed stone 41, coarse sand 42, medium sand 43 and activated carbon 44, and the thickness of each layer is 0.4 meters, thereby improving the practicality of the device.
[0035] Reference Figure 1-3 A sewage outlet 45 is provided inside the sewage pool 1, and the sewage outlet 45 is located in the filtering area 4; the sewage inlet 2 adopts a circular structure with a diameter of 1 meter and is made of stainless steel, thereby improving the practicality of the device.
[0036] Reference Figure 1-4A cleaning device 6 is provided inside the sewage pool 1 and below the filtration area 4. The cleaning device 6 includes an electric push rod 61, a U-shaped frame 62, a rotating shaft 63, a motor 631, a quarter main gear 632, a slave gear 633, a fixing block 64, a high-pressure water gun 65 and a long nozzle 66. By introducing the cleaning device 6, the problem of easy clogging of the traditional drainage structure is solved, the reliability and service life of the drainage structure are improved, and the practicality of the device is improved.
[0037] Reference Figure 1-4 The electric push rod 61 is fixedly connected to the sewage pool 1, and the telescopic end of the electric push rod 61 is fixedly connected to a U-shaped frame 62 located inside the sewage pool 1, and the internal rotation of the U-shaped frame 62 is connected to a rotating shaft 63; by starting the electric push rod 61, the U-shaped frame 62 is driven to move back and forth below the filter area 4 in the sewage pool 1. Since the multi-layer filter medium is from top to bottom and the pore size changes from large to small, the high-pressure water gun 65 sprays from bottom to top, which can better clean out the impurities in the multi-layer filter medium from the multi-layer filter medium, thereby improving the practicality of the device.
[0038] Reference Figure 1-4 The interior of the U-shaped frame 62 is fixedly connected to a motor 631, and the output end of the motor 631 is fixedly connected to a quarter main gear 632. One end of the rotating shaft 63 is fixedly connected to a slave gear 633, and the slave gear 633 is meshed with the quarter main gear 632; by starting the motor 631 to drive the quarter main gear 632 to rotate, the quarter main gear 632 is meshed with the slave gear 633 to cause the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, it will drive the high-pressure water gun 65 to rotate ninety degrees through the fixed block 64 connected thereto, thereby improving the practicality of the device.
[0039] Reference Figure 1-4 The outside of the rotating shaft 63 is fixedly connected to a fixed block 64, the inside of the fixed block 64 is fixedly connected to a high-pressure water gun 65, and the high-pressure water gun 65 is fixedly connected to a long nozzle 66; by arranging the long nozzle 66 on the high-pressure water gun 65, the ejected high-pressure water flow can be sprayed onto the multi-layer filter medium in an all-round manner, thereby making the high-pressure water gun 65 not only able to sweep back and forth but also to rotate and sweep, achieving a better cleaning effect, thereby improving the practicality of the device.
[0040] Working principle: Sewage enters the underground sewage pool 1 through the sewage inlet 2, which is used to receive sewage from the urban drainage pipe. It first passes through the sedimentation area 3, where large particles of impurities are precipitated. The sewage after preliminary sedimentation enters the filtration area 4. Through the filtering effect of multiple layers of filter media, suspended matter and small particles of impurities are further removed. The filtered sewage is discharged into the urban drainage system through the drainage pipe 5. The cleaning device 6 is started regularly to clean the filter medium to ensure that the drainage structure is unobstructed and prevent blockage.
[0041] By starting the electric push rod 61, the U-shaped frame 62 moves back and forth below the filter area 4 in the sewage pool 1. At the same time, the motor 631 is started to rotate the quarter main gear 632. The quarter main gear 632 engages with the slave gear 633 to cause the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, it will drive the high-pressure water gun 65 to rotate 90 degrees through the fixed block 64 connected thereto. When the high-pressure water gun 65 rotates to 90 degrees, the quarter main gear 632 loses engagement with the slave gear 633. Under the action of high pressure, the high-pressure water gun 65 is rotated, causing the high-pressure water gun 65 to rotate back and forth 90 degrees. By providing an elongated nozzle 66 on the high-pressure water gun 65, the ejected high-pressure water flow can be sprayed onto the multi-layer filter medium in an all-round manner. As a result, the high-pressure water gun 65 can not only sweep back and forth but also rotate and sweep, achieving a better cleaning effect. Since the multi-layer filter medium is from top to bottom and the pore size is large to small, the high-pressure water gun 65 sprays from bottom to top, so that impurities in the multi-layer filter medium can be better cleaned out of the multi-layer filter medium.
[0042] The sewage inlet 2 adopts a circular structure with a diameter of 1 meter and is made of stainless steel. The sedimentation area 3 is 1.5 meters deep and has an inclined bottom design to facilitate the discharge of sediment. The filtration area 4 uses four layers of filter media, namely gravel 41, coarse sand 42, medium sand 43 and activated carbon 44, each layer is 0.4 meters thick. The drainage pipe 5 has a diameter of 0.8 meters and is made of cast iron. The cleaning device 6 uses a high-pressure water gun 65 to regularly clean the filter media.
[0043] By setting up the sedimentation area 3 and the filtration area 4, preliminary sedimentation and deep filtration of the sewage are achieved, which effectively improves the sewage discharge efficiency. The introduction of the cleaning device 6 solves the problem of easy clogging of the traditional drainage structure and improves the reliability and service life of the drainage structure.

Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present application within the technical scope disclosed in the present application, and they should be covered by the protection scope of the present application.
