[0002] Sewers play a very important role in municipal administration. They are used to collect and discharge wastewater generated by urban roads in rainy weather and other conditions to ensure the city's sanitary environment and public health. However, since there are usually a lot of fallen leaves, mud and other impurities on urban roads, these impurities usually flow into the sewers with the water, causing the drainage pipes in the sewers to be blocked.

[0027] See also Figure 1-Figure 3 , Figure 1 This is a reference diagram of the water well structure in the embodiment. Figure 2 It is a schematic diagram of the structure of the sewer well and the sewer well filtering device in the embodiment, Figure 3 Schematic diagram of the structure of the filtering mechanism and the collecting mechanism in the embodiment. A sewer filter device in this embodiment includes a filtering mechanism 1 and a collecting mechanism 2, which are installed adjacent to each other at the wellhead of a sewer 0, and a well cover 01 is installed on the filtering mechanism 1 and the collecting mechanism 2. When in use, the filtering mechanism 1 is used to filter impurities, and the collecting mechanism 2 is used to collect impurities filtered by the filtering mechanism 1.

[0028] Specifically, the collecting mechanism 2 includes a mounting frame 21 and a collecting portion 22. One end of the mounting frame 21 is supported on the wellhead of the sewer, and the other end extends into the sewer. The collecting portion 22 is arranged at the end of the mounting frame 21 located in the sewer, and has a material receiving box 221. The top of the material receiving box 221 is provided with an opening 2211, and filter holes are evenly distributed on the bottom. The filtering mechanism 1 includes a mounting frame 11 and a first filter portion 12. The mounting frame 11 is adjacent to the mounting frame 21 and is arranged at the wellhead of the sewer, and also extends toward the sewer. The mounting frame 11 has a water inlet channel arranged through its upper and lower ends. The first filter portion 12 includes a guide plate 121. One end of the guide plate 121 is arranged on the inner wall of the mounting frame 11 away from the end of the collecting mechanism 2, and the other end extends obliquely downward to the opening 2211 of the material receiving box 221, and the bottom wall of the guide plate 121 is also evenly covered with filter holes.

[0029] During drainage, waste water passes through the manhole cover 01 and enters the filter mechanism 1. At this time, since the guide plate 121 is evenly covered with filter holes and the guide plate 121 is inclined, when the water flows through the guide plate 121, it will flow into the bottom of the sewer through the filter holes of the guide plate 121, and the impurities it carries will be filtered by the guide plate 121 and slide into the collecting box 221 along the guide plate 121. In this way, it can effectively prevent the accumulation of impurities on the guide plate 121 to block the filter holes and cause water accumulation on the road. When cleaning, you only need to lift the installation frame 11 upwards, take out the collecting box 221, pour out the collected impurities, and put them back, which effectively improves the convenience of impurity cleaning.

[0030] See also Figure 4-Figure 5 , review Figure 2-Figure 3 , Figure 4 This is a schematic diagram of the filter mechanism structure in the embodiment. Figure 5 for Figure 4Enlarged view of the middle A part. Preferably, the guide plate 121 includes a first plate body 1211 and a second plate body 1212, one end of the first plate body 1211 is mounted on the inner wall of the mounting frame 11, the second plate body 1212 is rotatably connected to the upper surface of the other end of the first plate body 1211, and the other end thereof extends to the opening 2211 of the receiving box 221, the first filter part 12 includes a traction part 122, the traction part 122 includes a second traction assembly 1222, the second traction assembly 1222 includes a guide ring 12221 and a second traction rope 12222, the guide ring 12221 is fixed to the outer wall of the mounting frame 11 close to one end of the collecting mechanism 2, one end of the second traction rope 12222 is fixed to the mounting frame 21, and the other end is fixed to the second plate body 1212 after passing through the guide ring 12221. In this way, the second plate 1212 can not only eliminate the gap between the guide plate 121 and the material receiving box 221, and prevent impurities from falling into the well through the gap between the two, but also, when the mounting frame 21 is lifted, the mounting frame 21 pulls the second traction rope 12222, and under the influence of the guide ring 12221, the second traction rope 12222 provides the second plate 1212 with a pulling force in the direction of the mounting frame 11, so that the second plate 1212 is reversed in the direction of the first plate 1211, so that the mutual interference between the guide plate 121 and the material receiving box 221 can be effectively avoided when taking and placing the material receiving box 221. It can also be understood that since the second plate 1212 is turned upward, the impurities on the first plate 1211 will be blocked by the second plate 1212, so it can also effectively prevent the impurities from falling into the well when the material receiving box 221 is replaced.

[0031] Review Figure 2-Figure 5 Furthermore, the filtering mechanism 1 also includes a second filtering part 13, and the second filtering part 13 includes a blocking plate 131. One end of the blocking plate 131 is installed on the inner wall of the mounting frame 11 close to the material receiving mechanism 2, and the other end thereof extends obliquely to the surface of the first plate body 1211. The surface of the blocking plate 131 is also evenly covered with filter holes.

[0032] Continue reviewing Figure 2-Figure 5One end of the first plate 1211 is rotatably connected to the inner wall of the installation frame 11, and the traction part 122 also includes a first traction assembly 1221, and the first traction assembly 1221 includes a first pulley 12211, a second pulley 12212, a counterweight 12213 and a first traction rope 12214. The first pulley 12211 is arranged at one end of the first plate 1211 close to the second plate 1212, and the second pulley 12212 is installed at the bottom of the installation frame 11 and is connected to the first pulley 12214. Relative to 12211, it has a U-shaped hanging piece 122121, one end of the first traction rope 12214 is fixed to the outer wall of the installation frame 11 close to one end of the collecting mechanism 2, and the other end of the first traction rope 12214 passes through the second pulley 12212, the first pulley 12121 and the U-shaped hanging piece 122121 in sequence, and then passes through the first plate body 1211 to the bottom of the first plate body 1211, and the counterweight 12213 is located under the first plate body 1211 and fixed to the other end of the first traction rope 12214. It can be understood that in the initial state, the counterweight 12213 has a tendency to fall due to the influence of gravity, so that the first pulley 12211 and the second pulley 12212 are kept close to each other, that is, one end of the baffle plate 131 is in contact with the surface of the guide plate 121. After the water flows through the filter holes of the guide plate 121 and the baffle plate 131, the surface of the guide plate 121 is blocked by the baffle plate 131, so the impurities carried by the water are accumulated on the guide plate 121 and the baffle plate 131. When the weight of the accumulated impurities is greater than the counterweight, the guide plate 121 rotates downward and lifts the configuration 12213 upward. At this time, a gap appears between the guide plate 121 and the baffle plate 131, and the impurities can slide into the material receiving box 221 along with the guide plate 121. In this way, it is further ensured that the impurities slide into the well through the guide plate 121 when the material receiving box 221 is replaced.

[0033] Preferably, the blocking plate 131 is rotatably connected to the inner wall of the installation frame 11, and the installation frame 11 is provided with a plurality of stoppers (not shown in the figure), which are arranged on the inner walls on both sides of the installation frame 11 and are located below the blocking plate 131, and the lower surface of the blocking plate 131 abuts against the stoppers (not shown in the figure). When the collection mechanism 2 is lifted, the second traction rope 12222 drives the second plate body 1212 to flip upward while also causing the first plate body 1211 to reverse upward. When the first plate body 1211 flips to contact the blocking plate 131, the blocking plate 131 slides along the surface of the guide plate 121 and rotates upward with the guide plate 121. It can be understood that, in this way, impurities are further prevented from sliding down to the bottom of the well along the guide plate 121 when replacing or cleaning the receiving box 221. At the same time, it can also prevent the guide plate 121 and the blocking plate 131 from colliding with each other and causing damage when the collecting mechanism 2 is lifted. By setting a limiter (not shown) under the blocking plate 131, it can be effectively prevented that when the guide plate 121 rotates downward, the blocking plate 131 is completely turned downward to a vertical state, causing the guide plate 121 to be unable to reset upward. In this example, the limiter (not shown) is a bolt.

[0034] In this example, both the blocking plate 131 and the first plate body 1211 are rotatably connected to the installation frame 11 by hinges. Similarly, the second plate body 1212 is also rotatably connected to the first plate body 1211 by hinges.

[0035] Preferably, in specific implementation, according to actual needs, for example, for a sewer with a lot of silt, a mesh can be covered on the guide plate 121, and a mesh bag can be provided in the material receiving box 221 to better filter and collect impurities such as silt.

[0036] Continue reviewing Figure 2-Figure 5 Furthermore, the guide plate 121 also has two guide side walls 1213, and the two guide side walls 1213 are respectively arranged on both sides of the upper surface of the guide plate 121, and each guide side wall 1213 includes a first section 12131 and a second section 12132 close to the second plate body 1212, wherein the spacing between the first sections 12131 of the two guide side walls 1213 is consistent with the width of the first plate body 1211, and the second section 12132 is arc-shaped, and the spacing between the two guide side walls 1213 gradually decreases from the first plate body 1211 toward the collecting device 2, wherein the second plate body 1212 also has two limiting walls 12121, and the spacing between the two limiting walls 12121 is greater than the spacing between the second sections 12132 of the two side walls 1213 close to one end of the second plate body 1212. In this way, when impurities slide along the surface of the guide plate 121, the two sides of the guide plate are restricted by the guide side walls 1213, which can effectively prevent the impurities from entering the bottom of the well from the two sides of the guide plate 121. When the impurities are close to the second plate body 1212, they are affected by the arc-shaped second section 12132 of the guide side wall 1213, and the impurities are more concentratedly slid through the second plate body 1212 to the material receiving box 221 for collection. At the same time, it can also be understood that when the second plate body 1212 is flipped upward, since the spacing between the two limiting walls 12121 is greater than the spacing between the second sections 12132 of the two side walls 1213 close to one end of the second plate body 1212, the second plate body 1212 is better blocked at one end of the first plate body 1211.

[0037] See also Figure 6-Figure 7 , review Figure 2-Figure 3 , Figure 6 This is one of the structural diagrams of the collection mechanism in the embodiment. Figure 7 The second structural diagram of the collection mechanism in the embodiment is shown in FIG. 2. Further, the mounting frame 21 includes a supporting horizontal plate 211 and two side plates 212. The supporting horizontal plate 211 is supported at the wellhead of the sewer. One end of the two side plates 212 is fixed to the supporting horizontal plate 211 and the other end extends into the sewer. The collection part 22 is installed between the two side plates 212.

[0038] Specifically, the mounting frame 21 also includes two support plates 213, which are respectively arranged on the outer walls of the two side plates 212, and one end of the support plate 213 is rotatably connected to one end of the side plate 212 close to the supporting cross plate 211, and the other end extends downward, and the length of the support plate 213 is less than the length of the side plate 212. When in use, when it is necessary to replace or clean the receiving box 221, the mounting frame 21 is lifted upward so that the support plate 213 is exposed outside the well, and the support plate 212 is rotated so that its bottom end is tilted outward. At this time, the support plate 213 can be supported at the wellhead of the sewer well 0, which is convenient for workers to replace or clean the receiving box 221, saving time and effort. In this example, the support plate 213 is also rotatably connected to the side plate 212 through a loose-leaf.

[0039] Furthermore, the lifting and traction assembly 231 includes a wire reel 2311, a third traction rope 2312 and a guide pulley 2313, wherein the inner wall of one side plate 212 near one end of the supporting horizontal plate 211 has a bearing platform 2121, and the supporting horizontal plate 211 is provided with a through hole 2111 corresponding to the bearing platform 2121, and the wire reel 2311 is installed on the bearing platform 2121, and one end thereof passes through the through hole 2111 and is exposed to the outside of the wellhead, and the guide pulley 2313 is arranged at the bottom center of the supporting horizontal plate 211, and one end of the third traction rope 2312 is wound around the wire reel 2311, and the other end passes through the guide pulley 2313 and is fixed to the crossbeam 23211. In this example, the wire reel 2311 adopts a hand crank of a lifting clothes drying rack.

[0040] The lifting part 23 further includes two groups of lifting guide assemblies 233, which are respectively arranged on the inner walls of the two side panels 212 facing each other, and each group of lifting guide assemblies 233 includes a telescopic rail assembly 2331 and a guide plate 2332. The telescopic rail assembly 2331 is arranged on the inner wall of the side panel 212, and the guide plate 2332 includes a plate body 23321 and two limit plates 23322. The plate body 23321 is installed on the telescopic rail assembly 2331, and the two limit plates 23322 are respectively installed on both sides of a side of the plate body 23321 facing away from the telescopic rail assembly 2331, and a limit space is formed between the plate body 23321, and the two ends of the load-bearing frame 2321 are respectively located in the limit spaces of the two groups of lifting guide assemblies 233. In this example, the telescopic rail assembly 2331 adopts a drawer guide rail.

[0041] During use, in the initial state, the bottom of the guide plate 2332 abuts against the bottom of the sewer well 0, and the material receiving box 221 is also located at the bottom of the well. The worker can use a hand-cranked tool such as a hexagonal wrench to control the wire reel 2311 to release the wire, so that the third traction rope 2312 between the material receiving box 221 and the wire reel 2311 is of excess length. In this way, when the mounting frame 21 is lifted, under the influence of gravity, the guide plate 2332 and the material receiving box 221 remain motionless at the bottom of the sewer well 0, and the telescopic rail assembly 2331 is extended. In this way, the worker can easily lift the mounting frame 21 out and set it up at the wellhead. At this time, the worker can control the wire reel 2311 again to reel in the wire, thereby lifting the material receiving box 221 upward between the two limit plates 23322 to replace or clean the material receiving box 221, thereby further facilitating the worker to clean the material receiving box, saving time and effort. After the cleaning is completed, the material receiving box 221 is lowered to the bottom of the manhole 0 by the reel 2311 again. At this time, the mounting frame 21 is put back into the manhole 0 according to the reverse steps.

[0042] That is, in this example, by providing a filtering mechanism with an inclined filter plate, it is effectively prevented that the filtered impurities clog the guide plate and cause water accumulation on the road surface. By providing a collecting mechanism with a material receiving box, the filtered impurities are effectively concentrated and easy to clean.

[0043] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
