Detailed implementation method
[0017] Embodiment 1
[0018] Please refer to Figures 1-3 , a deodorization device for municipal engineering sewers, including a manhole cover 2 and an installation ring 3. The manhole cover 2 and the installation ring 3 are used in combination. An installation sleeve 1 is fixedly connected to the installation ring 3. An opening and closing mechanism and a flushing mechanism are installed on the installation sleeve 1. The opening and closing mechanism includes a slope 10, a rubber sheet I 11 and an extension plate 12. The slope 10 is detachably connected to the side wall of the installation sleeve 1. A plurality of rubber sheets I 11 are fixedly connected to the slope 10. A middle plate 18 is placed on the rubber sheet I 11. The extension plate 12 is elastically slidably connected to the middle plate 18. The middle plate 18 is rotatably connected to the installation sleeve 1 through a rotating shaft 13. A rubber sheet II 20 is fixedly connected inside the installation sleeve 1. The rubber sheet I 11 and the rubber sheet II 20 are in contact with each other. On one side of the rotating shaft 13, there is a flushing mechanism for controlling the rotation of the rotating shaft 13.
[0019] A cavity is opened in the rotating shaft 13, and a counterweight is fixedly connected inside the cavity.
[0020] In this embodiment, during use, the installation ring 3 is clamped into the ground, and then the manhole cover 2 is covered on the installation ring 3. The installation sleeve 1 extends into the manhole. Under normal circumstances, the counterweight in the rotating shaft 13 serves to stabilize the rotating shaft 13, so that the rotating shaft 13 can always drive the middle plate 18 to be in a closed state. The so-called closed state means that the extension plates 12 on both sides of the middle plate 18 are unfolded, so that the extension plates 12 and the middle plate 18 together are in contact with a plurality of rubber sheets I 11, and the rubber sheet I 11 is also in contact with the rubber sheet II 20. At this time, the closed mouth formed by the rubber sheet I 11 and the rubber sheet II 20 together can block the upward rise of the odor below the slope 10, thus achieving the purpose of deodorizing the sewer in this design. When draining water, the sewage enters the installation sleeve 1 from the manhole cover 2, and the water accumulates on the rubber sheet I 11 and the rubber sheet II 20. When the gravity of the water flow reaches a certain level, the rubber sheet I 11 and the rubber sheet II 20 are deformed, and the water flow can thus pass through the rubber sheet I 11 and the rubber sheet II 20 and enter the manhole, so that the purpose of draining water can be achieved. After the drainage process ends, the rubber sheet I 11 and the rubber sheet II 20 return to their original positions. Therefore, this design takes into account both the functions of deodorization and drainage and has practicality.
[0021] Embodiment 2
[0022] Please refer toFigures 1-5 , on the basis of the above embodiments, the flushing mechanism includes a water tank 4, a valve 5, a second pipeline 6, a fan blade 14, a foam ball 15, a guide rod 16 and a first conductive sheet 17. The valve 5 is installed on the second pipeline 6, and the second pipeline 6 is used to connect the water tank 4 and an external water pipe. The water tank 4 is connected to the installation sleeve 1 through a first pipeline 9. A guide rod 16 is rotatably connected to the water tank 4. A foam ball 15 is fixedly connected to the free end of the guide rod 16. A first conductive sheet 17 is fixedly connected to one end of the guide rod 16 close to the water tank 4. The first conductive sheet 17 is connected in series with the mains electricity. A second conductive sheet 19 is fixedly connected to the water tank 4. The second conductive sheet 19 is connected in series with the single-chip microcomputer on the valve 5. When the first conductive sheet 17 and the second conductive sheet 19 are in contact, the circuit is connected, and the mains electricity enters the single-chip microcomputer in the valve 5. The single-chip microcomputer receives the current change and controls the valve 5 to open according to a preset duration, and the water flow of the external water pipe enters the water tank 4. A fan blade 14 is fixedly connected to the rotating shaft 13, and the fan blade 14 is located on the water outlet path of the first pipeline 9. A pressure valve 21 is installed on the first pipeline 9. The diameter of the second pipeline 6 is larger than that of the first pipeline 9.
[0023] A flushing mechanism is provided on one side of the slope 10, and the slope 10 is located below the first pipeline 9.
[0024] An end cover 7 is placed on the water tank 4, and a drain port 8 is opened on the end cover 7.
[0025] In this embodiment, the water tank 4 is used to collect the falling rainwater and discharge the water flow in the water tank 4 at an appropriate time to wash the first rubber sheet 11 and the second rubber sheet 20. Specifically, when it rains outside, the rainwater enters the water tank 4 through the drain port 8. At this time, the water tank 4 collects the rainwater. When the amount of rainwater in the water tank 4 reaches a certain level, the pressure accumulated by the rainwater will force the pressure valve 21 to open. At this time, the rainwater will flow out through the first pipeline 9 and hit the fan blade 14, causing the fan blade 14 to drive the rotating shaft 13 to rotate. The rotating rotating shaft 13 drives the extension plate 12 and the middle plate 18 to rotate synchronously. When the extension plate 12 presses against the multiple first rubber sheets 11, the first rubber sheets 11 bend downward, so that the fallen leaves and dust accumulated on the first rubber sheets 11 can flow into the manhole along the water flow discharged from the first pipeline 9, so as to achieve the purpose of regularly cleaning the deposits on the first rubber sheet 11 and the second rubber sheet 20. After the rainwater stops impacting the fan blade 14, the rotating shaft 13 can return to its original position by virtue of the counterweight. When there is not enough rainwater collected in the water tank 4 in dry weather, the foam ball 15 drives the guide rod 16 to rotate downward under the action of gravity. At this time, the first conductive sheet 17 and the second conductive sheet 19 are in contact, and the circuit is connected. The single-chip microcomputer in the valve 5 receives the current change. The element sensing this change is a sensor. Since there are corresponding sensors on the market, the means by which the valve 5 receives the current change through the single-chip microcomputer is prior art. The valve 5 opens, and the water tank 4 introduces external water source to fill the water tank 4. When there is enough water in the water tank 4, the foam ball 15 is buoyed by the water, thus driving the guide rod 16 to rotate upward, so that the first conductive sheet 17 and the second conductive sheet 19 are separated from each other. At this time, the circuit is disconnected, and the valve 5 automatically closes after continuously opening for a period of time under the control of the single-chip microcomputer; the pressure valve 21 opens under the action of the water flow pressure in the water tank 4, impacts the fan blade 14, and drives the rotating shaft 13 to rotate, repeating the above cleaning process. It should be further noted that let the water level corresponding to the upper pressure limit of the pressure valve 21 be A, at this time the pressure valve 21 is opened correspondingly, the water level corresponding to the lower pressure limit of the pressure valve 21 be B, at this time the pressure valve 21 is closed correspondingly, the water level when the valve 5 is opened be C, and the water level when the valve 5 is closed be D. Then there is the following relationship between the water levels, that is, D is greater than A is greater than B is greater than C. Because the diameter of the second pipeline 6 is larger than that of the first pipeline 9, the water inlet speed of the second pipeline 6 is greater than the water drainage speed of the first pipeline 9. Therefore, the water level in the water tank 4 rises per unit time. When the water level reaches D, the valve 5 closes, the pressure valve 21 opens, and the water tank 4 discharges water flow to the outside. After that, when the water level drops to B, the pressure valve 21 closes, and the water tank 4 stops discharging water flow to the outside. After that, when the weather is dry and the water in the water tank 4 is evaporated, and the water level drops to C, the valve 5 opens and repeats the above process. Since the single-chip microcomputer receiving the current change is prior art, and the single-chip microcomputer can control the opening time of the valve 5, which is also common in the control methods of the single-chip microcomputer, using the single-chip microcomputer to control the valve 5 to open for a period of time is prior art, and this period of time can be input into the single-chip microcomputer manually.Therefore, in summary, this design can not only achieve the purpose of preventing odors, but also combine with information technology to enable this design to regularly clean the fallen leaves and sundries on the first rubber sheet 11 and the second rubber sheet 20, reducing the probability of sewer blockage.
