Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a box culvert type interception well used for intercepting sewage in urban rivers. Background Art

[0002] Many rivers have been dug in many cities. Urban rivers not only beautify the city, but can also be used to discharge floodwaters during the rainy season. However, sewage is inevitable in the rivers. The sewage will enter the box culvert intercepting well through the corresponding pipes, and then enter the sewage treatment plant.

[0003] An interception well is a well that concentrates some polluted water flows into, and this well leads to a sewage treatment plant. If there is no such well, in order for sewage to enter the sewage treatment plant, every pipe must enter the sewage treatment plant. A well is used in front to intercept these sewage, and the number of pipes to the sewage treatment plant will be greatly reduced, which is also conducive to collecting sewage. Such a well is a sewage interception well. The existing interception wells can be specifically referred to the Chinese utility model patent with application number: CN201922011395.6, which discloses in detail: an interception well, wherein a retaining wall is arranged inside the interception well, and the retaining wall divides the interception well into an inner well and an outer well, and an inlet pipe and an interception pipe are arranged on the well wall of the inner well, and a water outlet pipe is arranged on the well wall of the outer well; the retaining wall is provided with an overflow hole and a drain hole, and the position of the overflow hole is higher than the position of the drain hole, and the overflow hole is close to the top of the retaining wall; the overflow hole is provided with an interception component for intercepting suspended matter and / or floating matter. By adopting the utility model, the overflow liquid level of the interception well can be effectively raised, and then the pipe network can be used as a storage measure to effectively avoid or reduce overflow to reduce external river pollution.

[0004] However, river sewage now enters the interception well through corresponding pipes, and it is inevitable that some large stones will be mixed in the sewage. These stones enter the sewage treatment plant in a concentrated manner, which may cause blockage of the sewage treatment plant pipes and make it more difficult for the sewage treatment plant to carry out sewage treatment. Utility Model Content

[0005] The purpose of the utility model is to provide a box culvert type intercepting well for intercepting sewage in urban rivers, so as to solve the problem raised in the above-mentioned background technology that when sewage from rivers enters the intercepting well through corresponding pipes, some large stones will inevitably be mixed in the sewage. These stones will enter the sewage treatment plant in a concentrated manner, which may cause blockage of the sewage treatment plant pipes and increase the difficulty of sewage treatment in the sewage treatment plant.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a box culvert type interception well for intercepting sewage in urban rivers, comprising a box culvert, a plurality of sets of flow pipes are fixedly connected to the outer side of the bottom end of the box culvert, a sewage pipe is fixedly connected to one side of the bottom end of the box culvert, a limiting flow orifice plate is fixedly connected to the bottom end of the box culvert, a moving mechanism is arranged inside the box culvert, the moving mechanism comprises a moving groove, and the moving groove is arranged in two groups, the moving groove is opened on both sides of the box culvert, the top and bottom ends of the moving groove are rotatably connected with a screw, the outer side of the screw is threadedly connected with a moving block, a filter plate is arranged inside the box culvert, both sides of the filter plate are fixedly connected to the moving block, the bottom end of the filter plate is fixedly connected with a placement plate, and a plurality of filter holes are opened on one side of the filter plate.

[0007] Preferably, rotating wheels are arranged on both sides of the top of the box culvert, the rotating wheels penetrate the box culvert and are fixedly connected to the screw rod, and transmission belts are arranged on the outer sides of the two groups of rotating wheels.

[0008] Preferably, a protective shell is provided on the outer side of the rotating wheel, the protective shell is fixedly connected to the culvert, one end of the protective shell is fixedly connected to a motor, and the output end of the motor passes through the protective shell and is fixedly connected to one group of rotating wheels.

[0009] Preferably, the moving block is completely inside the moving groove, and the size of the moving block is adapted to the moving groove.

[0010] Preferably, two groups of positioning holes are opened at the top of the placement plate, a chip storage plate is arranged at the top of the placement plate, and two groups of positioning blocks are fixedly connected to the bottom end of the chip storage plate, and the positioning blocks are in the positioning holes.

[0011] Preferably, a handle is provided at the top of the chip storage plate, and the handle is provided in two groups, and the handle is fixedly connected to the chip storage plate.

[0012] Preferably, a plurality of through holes are provided on one side of the flow limiting orifice plate, and the diameter of the through holes is larger than the diameter of the filter holes.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up a mobile mechanism and a filter plate, the sewage from each river channel entering the box culvert from the combined pipe will first be filtered through the filter plate to filter some larger stones. When the number of filtered stones reaches a certain level, the motor can be turned on to rotate the screw to drive the placement plate and the chip storage plate to rise, and then these large stones can be processed in the interception well. This solves the problem that the river sewage enters the interception well through the corresponding pipeline, and the sewage will inevitably be mixed with some larger stones. These stones will enter the sewage plant in a concentrated manner, which may cause the sewage plant pipeline to be blocked, and it will also make it more difficult for the sewage plant to treat sewage;

[0015] 2. By setting up a rotating wheel and a transmission belt, since the stable rise of the placement plate requires the simultaneous rotation control of two sets of screw rods, the same set of transmission belts are sleeved on the outer side of the rotating wheel connected to the two sets of screw rods. The rotation of one set of rotating wheels can drive the rotation of the other set of rotating wheels. Therefore, only one set of motors is needed to control the rotation of one set of rotating wheels to control the two sets of screw rods. This reduces the setting of motors and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides a technical solution: a box culvert type interception well for intercepting sewage in urban rivers, comprising a box culvert 1, a plurality of combined flow pipes 2 are fixedly connected to the outer side of the bottom end of the box culvert 1, a sewage pipe 3 is fixedly connected to one side of the bottom end of the box culvert 1, a limited flow orifice plate 4 is fixedly connected to the bottom end of the box culvert 1, a moving mechanism is arranged inside the box culvert 1, the moving mechanism comprises a moving groove 5, and the moving groove 5 is arranged in two groups, the moving groove 5 is opened on both sides of the inside of the box culvert 1, the top and bottom of the moving groove 5 are rotatably connected with a screw rod 6, the outer side of the screw 6 is threadedly connected with a moving block 7, a filter plate 8 is arranged inside the box culvert 1, both sides of the filter plate 8 are fixedly connected to the moving block 7, the bottom end of the filter plate 8 is fixedly connected with a placement plate 9, and one side of the filter plate 8 is provided with a plurality of filter holes 10, A plurality of combined flow pipes 2 are connected to a plurality of groups of urban rivers, and the sewage from the plurality of groups of rivers is concentrated into the box culvert 1 through the combined pipe 2. The concentrated sewage will pass through the filter plate 8 and then enter the flow limiting orifice 4 and then lead to the sewage treatment plant's sewage pipe 3. The flow limiting orifice 4 can adjust the flow rate of the sewage to prevent excessive water flow from entering the sewage treatment pipe 3. Due to the obstruction of the filter holes 10 on the filter plate 8, many larger stones will be blocked by the filter plate 8 and cannot enter the sewage treatment pipe 3, and these stones will fall on the chip storage plate 16 at the top of the placement plate 9. When too many stones accumulate on the chip storage plate 16, the motor 14 can be turned on to rotate the two sets of screws 6 to drive the placement plate 9 and the chip storage plate 16 to rise, and then centralized treatment can be carried out.

[0024] See also Figure 3 and Figure 5 Since the stable rise of the placement plate 9 requires the simultaneous rotation control of the two sets of screw rods 6, after the outer side of the rotating wheels 11 connected to the two sets of screw rods 6 is sleeved with the same set of transmission belts 12, the rotation of one set of rotating wheels 11 can drive the rotation of the other set of rotating wheels 11, so only one set of motors 14 is needed to control the rotation of one set of rotating wheels 11, so that the two sets of screw rods 6 can be controlled. This reduces the setting of the motor 14 and reduces the production cost. The rotating wheels 11 are arranged on both sides of the top of the box culvert 1. The rotating wheels 11 penetrate the box culvert 1 and are fixedly connected with the screw rods 6, and the outer sides of the two sets of rotating wheels 11 are sleeved with transmission belts 12. The outer sides of the rotating wheels 11 are provided with protection belts. The protective shell 13 is fixedly connected to the culvert 1, and the protective shell 13 can prevent the transmission belt 12 from falling off the rotating wheel 11 when the transmission belt 12 rotates. A motor 14 is fixedly connected to one end of the protective shell 13, and the output end of the motor 14 passes through the protective shell 13 and is fixedly connected to one group of rotating wheels 11. The moving block 7 is completely inside the moving groove 5, and the size of the moving block 7 is adapted to the moving groove 5. When the screw 6 rotates, the moving block 7 has a tendency to rotate together with the screw 6. Since the size of the moving block 7 is adapted to the moving groove 5, the tendency of the moving block 7 to rotate is hindered by the moving groove 5, so the moving block 7 can rise or fall as the screw 6 rotates.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 Two groups of positioning holes 15 are provided at the top of the placing plate 9, and a chip storage plate 16 is provided at the top of the placing plate 9. Two groups of positioning blocks 17 are fixedly connected to the bottom of the chip storage plate 16. The positioning blocks 17 are in the positioning holes 15. The position of the chip storage plate 16 installed on the placing plate 9 can be determined by the engagement of the positioning blocks 17 with the positioning holes 15. A handle 19 is provided at the top of the chip storage plate 16, and two groups of handles 19 are provided. The handle 19 is fixedly connected to the chip storage plate 16. When the placing plate 9 rises and drives the chip storage plate 16 to rise, the chip storage plate 16 loaded with stones can be lifted by the handle 19 and then the stones can be processed. A plurality of groups of through holes 18 are provided on one side of the flow limiting orifice plate 4, and the diameter of the through holes 18 is larger than the diameter of the filter hole 10. The plurality of through holes 18 on one side of the flow orifice plate can reduce the flow rate of sewage flowing into the sewage pipe. At the same time, the diameter of the through holes 18 is larger than the diameter of the filter hole 10, which can ensure that the sewage passing through the filter plate 8 can pass through the through holes 18 smoothly without being blocked at the through holes 18.

[0026] Working principle: Multiple combined flow pipes 2 are connected to multiple groups of urban rivers, and the sewage from multiple groups of rivers is concentrated into the box culvert 1 through the combined pipe 2. The concentrated sewage will pass through the filter plate 8 and then enter the flow limiting orifice 4 and then lead to the sewage treatment plant's sewage pipe 3. The flow limiting orifice 4 can adjust the flow rate of the sewage to prevent excessive water flow from entering the sewage treatment pipe 3. Due to the obstruction of the filter holes 10 on the filter plate 8, many larger stones will be blocked by the filter plate 8 and cannot enter the sewage treatment pipe 3, and these stones will fall on the chip storage plate 16 at the top of the placement plate 9. When there are too many stones accumulated on the chip storage plate 16, the motor 14 can be turned on to drive the rotating wheel 11 connected to it to rotate. The movement drives the transmission belt 12 and another set of rotating wheels 11 to rotate, thereby causing the two sets of screw rods 6 to rotate, so that the moving block 7 will rise and drive the placement plate 9 and the chip storage plate 16 to rise. At this time, the chip storage plate 16 and the stones deposited thereon can be taken out for treatment through the handle 19 on the chip storage plate 16. After the treatment, the positioning block 17 at the bottom of the chip storage plate 16 is engaged with the positioning hole 15 at the top of the placement plate 9 to complete the installation of the chip storage plate 16, and then the motor 14 is turned on in reverse to return the placement plate 9 to its original position. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
