Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a new type of rainwater and sewage separation well for municipal use. Background Technology

[0002] In older urban areas, drainage systems often use a combined sewer system, where rainwater and sewage share municipal drainage pipes, which can easily lead to overflows, backflows, and pollution of rivers and lakes. As cities develop, new urban areas are required to adopt a separate sewer system, and older combined sewer systems should be upgraded to separate rainwater and sewage systems. This upgrade typically involves separate rainwater and sewage facilities, which use separate wells to isolate the sewage system from the rainwater system.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figure 1-11 A new type of rainwater and sewage separation well for municipal use includes a hollow well body 1, an inlet pipe 2 at one end of the well body 1, and a sewage pipe 4 installed through the bottom of one side wall. A filter plate 3 is installed in the middle of the well body 1, and a first sealing plate 5 is provided on the inner side of the well body 1 at the position of the sewage pipe 4 opening.

[0037] Movable rods 6 are fixedly connected to both sides of the top of the first sealing plate 5. Sleeves 7 are fixedly connected to the side wall of the well body 1 at the positions above the two movable rods 6. The sleeve 7 is a hollow structure, and a movable head 8 is slidably connected to the bottom of its interior. The top of the movable rod 6 moves through the bottom of the sleeve 7 and is fixedly connected to the movable head 8. A compression spring 9 is installed between the top of the movable head 8 and the top of the inner side of the sleeve 7.

[0038] An L-shaped rod 10 is fixedly connected to the side of the first sealing plate 5. A first float plate 11 is fixedly connected to the top of the L-shaped rod 10. A receiving rod 12 is fixedly connected to the top of one end of the first float plate 11. A hollow rod 13 is installed at the top of the side wall of the well body 1 above the receiving rod 12. A protrusion 14 is slidably connected to the bottom of the inner side of the hollow rod 13. The top of the receiving rod 12 moves through the bottom of the hollow rod 13 and connects with the protrusion 14. A conductive seat 15 is provided on the upper inner side of the hollow rod 13. A recess is opened in the middle of the bottom of the conductive seat 15. A static switch 17 is fixedly installed at the top of the notch 16, and a dynamic switch 18 is slidably connected to the bottom of the inner side of the notch 16. A motor 19 is installed at the tail end of the sewage pipe 4, and a spiral conveyor blade 20 is installed inside the sewage pipe 4. One end of the output shaft of the motor 19 is connected to the rod end of the spiral conveyor blade 20. A sewage outlet 21 is opened on one side of the bottom end of the sewage pipe 4. The static switch 17 is electrically connected to the motor 19, and the dynamic switch 18 is electrically connected to the external power supply. The protrusion 14 can be slidably inserted into the inner side of the notch 16.

[0039] In the above-mentioned technical solution, the first sealing plate 5 is used to block the opening of the sewage pipe 4. The filter plate 3 divides the inner side of the well body 1 into two cavities. Sewage is discharged after filtration, while impurities and sludge are blocked in one of the cavities. When enough sludge accumulates, the water level in the cavity rises. The rise in water level will drive the first float plate 11 to rise. The rise of the first float plate 11 will drive the first sealing plate 5 to move upward, thereby gradually opening the opening of the sewage pipe 4 and discharging the sludge. When the first float plate 11 rises to the corresponding height, its end will drive the top of the receiving rod 12 to slide upward inside the hollow rod 13, thereby driving the protrusion 14 to move upward until the protruding part of the top of the protrusion 14 is inserted into the recess 16 at the bottom of the conductive seat 15. The protrusion 14 will drive the active switch 18 to move upward until it contacts the static switch 17 and is electrically connected, thereby turning on the motor 19 and starting the spiral conveyor blade 20 to work, thus facilitating the better transport of sludge.

[0040] The functions of the movable rod 6, sleeve 7, and compression spring 9 are not only to guide the first sealing plate 5, but also to promote the reset of the first sealing plate 5 when the water level drops. The buoyancy of the first float plate 11 is greater than the maximum compression force of the compression spring 9.

[0041] Both sides of the active switch 18 are fixedly connected to the first limiting block 23, and both sides of the inner wall of the recess 16 are provided with the first limiting groove 22 for the first limiting block 23 to slide.

[0042] The technical solution adopted above can limit the range of motion of the active switch 18 through the action of the first limiting block 23 and the first limiting groove 22, so that it will not fall off the conductive base 15.

[0043] The top two sides of the conductive base 15 are connected to the return spring 24, and the top of the return spring 24 is fixed to the top of the inner wall of the hollow rod 13. The conductive base 15 is fixed to both sides of the second limiting block 26. The inner wall of the hollow rod 13 is provided with the second limiting groove 25 for the second limiting block 26 to slide. The outer ring of the protrusion 14 and the bottom outer ring of the conductive base 15 are equipped with ring magnets 46 that can attract each other.

[0044] The above-mentioned technical solution, through the action of the second limiting groove 25 and the second limiting block 26, can limit the range of motion of the conductive seat 15. The return spring 24 ensures the initial position of the conductive seat 15 when it does not deform. At this time, the conductive seat 15 can move up and down within a small range. When the protrusion 14 is inserted into the inner side of the conductive seat 15 and causes the active switch 18 and the static switch 17 to connect, if the first float plate 11 has a tendency to drive the protrusion 14 to continue moving upward, it can drive the conductive seat 15 to move upward and compress the return spring 24. After the water level drops... When the protrusion 14 moves down, and the conductive seat 15 returns to its initial position while the first float plate 11 continues to descend, the dynamic switch 18 and the static switch 17 will remain connected for a period of time due to the attraction of the annular magnet 46. At this time, the attraction will cause the conductive seat 15 to move down and stretch the reset spring 24 until the conductive seat 15 slides to its maximum range and the protrusion 14 separates from the conductive seat 15. At this time, the reset spring 24 will drive the conductive seat 15 to reset. The electrical connection maintained during this period of time can cause the spiral conveyor blade 20 to transport the sludge in the sewage pipe 4 out.

[0045] It should be noted that the above situation occurs when the water inlet pipe 2 delivers a large amount of water and there is a lot of silt accumulation in the well body 1, allowing the water level to rise rapidly, thereby ensuring the connection between the dynamic switch 18 and the static switch 17.

[0046] Example 2, and as shown in the appendix Figure 12 As shown, the L-shaped rod 10 can also be set as a telescopic rod, but its telescopic length is less than the distance that the top of the protrusion 14 moves to the inside of the recess 16 at the beginning. The form of the telescopic rod can ensure that the first float plate 11 rises a certain distance without driving the first sealing plate 5 to move until the maximum telescopic amount is reached, driving the first sealing plate 5 to move upward and making the switch contact open. The hollow rod 13 is set to be able to move upward within a certain range. A sleeve is fitted on its outer side and the sleeve is fixed to the inner wall of the well body 1, thereby ensuring that the hollow rod 13 can move upward a certain distance, so that the first float plate 11 can drive the first sealing plate 5 to continue to move upward to open the sewage pipe 4, and ensure the effective contact connection of the switch.

[0047] A guide rod 27 is fixedly connected to the top of the other end of the first float plate 11, and a guide ring 28 is fixedly connected to the other side of the inner wall of the well body 1, and the guide rod 27 slides through the guide ring 28.

[0048] The technical solutions adopted above ensure that the guide rod 27 and guide ring 28 guarantee the stable vertical upward movement of the first float plate 11.

[0049] A rotating rod 29 and a transmission rod 30 are rotatably installed on the lower side of the well body 1. The tail end of the sewage pipe 4 is connected to a motor support 31 through multiple fixed rods, and the motor 19 is installed on the motor support 31. The rod of the spiral conveyor blade 20 extends to the outside of the sewage pipe 4 and is fixedly fitted with a first belt drive wheel 32. Both ends of the transmission rod 30 are fixedly connected with second belt drive wheels 33, and the first belt drive wheel 32 is connected to the second belt drive wheel 33 at one end of the transmission rod 30 through a transmission belt. The end of the rotating rod 29 located on the outside of the well body 1 is fixedly connected with a third belt drive wheel 34, and the third belt drive wheel 34 is connected to the second belt drive wheel 33 at the other end of the transmission rod 30 through a transmission belt. Multiple sets of crushing rods 35 distributed in a ring are evenly installed on the rod of the rotating rod 29 located on the inside of the well body 1.

[0050] The above-mentioned technical solution, through the operation of motor 19, can drive the rotating rod 29 at the bottom of well body 1 to rotate through the transmission wheel, transmission belt and transmission rod 30 and other structures. The rotation of rotating rod 29 will drive the crushing rod 35 to work, thereby crushing the sludge and facilitating its discharge.

[0051] Drainage pipes 36 are installed at both the upper and lower positions of the other end of the well body 1. A second sealing plate 37 is set on the inner side of the well body 1 at the position of the upper drainage pipe 36. Guide rails 38 are symmetrically installed on both sides of the inner wall of the other end of the well body 1. The two ends of the second sealing plate 37 are slidably connected to the inner side of the guide rails 38. An L-shaped connecting rod 39 is fixed to the side of the second sealing plate 37, and a second float plate 40 is connected to the top of the L-shaped connecting rod 39.

[0052] In the above-mentioned technical solution, the guide rail 38 is used to ensure the stable up-and-down movement of the second sealing plate 37 and limit it to a certain range. When the drainage volume is large and the water level is high, the second float plate 40 rises, causing the upper drainage pipe 36 to open, thereby increasing the drainage speed.

[0053] The well body 1 has symmetrically installed support seats 41 on both sides of the middle of the inner wall, and the filter plate 3 is inserted between the two support seats 41. The filter plate 3 is fixedly connected to both sides of the support seat 41. The support seat 41 has a slot 42 for the insertion plate 43 to slide into on the side near the filter plate 3. The top of the support seat 41 has a guide groove 44 that communicates with the top of the slot 42. A baffle 45 is slidably installed in the guide groove 44.

[0054] The above-mentioned technical solution uses filter plate 3 to be installed by insertion, which simplifies the installation method and facilitates its replacement or maintenance. The function of baffle 45 is to fix the position of filter plate 3. Baffle 45 has fixing blocks on both sides and fixing grooves on both sides of the inner wall of guide groove 44. Its function is to limit the direction and range of movement of baffle 45. One end of baffle 45 can slide and fit against the corresponding insert plate 43.

[0055] Working principle:

[0056] When a large amount of silt accumulates in the well body 1 and the water level rises rapidly, the first float plate 11 will rise and drive the first sealing plate 5 to move upward, thereby opening the sewage pipe 4. When the first float plate 11 rises to the corresponding height, it will cause the dynamic switch 18 and the static switch 17 to come into contact and be energized through the action of the receiving rod 12 and the protrusion 14, so that the motor 19 will start, thereby making the spiral conveying blade 20 in the sewage pipe 4 start working, accelerating the conveying of silt. At the same time, through the setting of related transmission structures, the motor 19 will drive the rotating rod 29 and the crushing rod 35 to work, stirring and breaking up the silt at the bottom of the well body 1, so that it can be better conveyed out of the sewage pipe 4.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
