Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a rainwater and sewage separation device for the renovation of old residential areas. Background Technology

[0002] Drainage engineering is an important part of urban infrastructure, covering the collection, transportation, treatment and discharge of various types of sewage such as domestic sewage, industrial wastewater and rainwater. It is of great significance to ensure the normal operation of the city and maintain the ecological environment. The drainage of old residential areas suffers from problems such as unreasonable design, aging facilities and poor management. The aging and blockage of drainage pipe networks occur frequently, especially during the rainy season, causing water accumulation in the community and causing great inconvenience to residents.

[0003] A search revealed Chinese patent publication number CN212200687U, which discloses a rainwater and sewage separation device. It includes: a housing comprising a first inlet and a second inlet, the first inlet for injecting liquid into the housing and the second inlet for discharging liquid out of the housing; a first cavity and a second cavity, both located below the second inlet. The first cavity has a first collection port on its side facing the second inlet, and the second cavity has a second collection port on its side facing the second inlet. The horizontal distance between the two collection ports is greater than the horizontal distance between the first and second collection ports. Compared to methods controlled by electronic valves, this method is simpler in structure, has lower construction costs, and is easier to disassemble and maintain. However, in practical use, while this structure collects rainwater through the collection ports, it lacks the function of screening for leaves and impurities carried by the rainwater. These leaves and impurities will still enter the drainage network with the water flow, causing long-term accumulation and blockage of the network. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rainwater and sewage separation device for the renovation of old residential areas, which aims to improve the problem that leaves and impurities in the existing technology still enter the drainage pipe network with the water flow, and long-term accumulation will cause pipe network blockage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rainwater and sewage diversion device for the renovation of old residential areas, comprising a diversion chamber, a rotating shaft rotatably connected to the rear side of the inner wall of the diversion chamber, a mounting shell rotatably connected to the front side of the rotating shaft, a filter plate provided on the front side of the mounting shell, the top of the filter plate engaging with the bottom of the mounting shell, rotating plates rotatably connected to the left and right ends of the front side of the mounting shell, a fixing block fixedly connected to the bottom of the rotating plate, two fixing grooves opened in the middle of the top wall of the mounting shell and the top of the front side of the filter plate, the bottom of the fixing block engaging with the fixing grooves, two fixing shells fixedly connected to the front side of the middle of the inner wall of the diversion chamber, the bottom of the filter plate engaging with the top wall of the fixing shell, bolts threadedly connected to the left and right ends of the bottom front side of the filter plate, the bottom ends of the bolts threadedly connected to the top wall of the fixing shell, a movable plate rotatably connected to the middle of the front side of the diversion chamber, a collection shell provided at the bottom front side of the diversion chamber, and impurity collection mechanisms provided at the bottom left and right sides of the diversion chamber.

[0006] The above technical solution enables the collection of rainwater and sewage through the diversion chamber connection. The tilted filter plate can intercept leaves and impurities in the rainwater, allowing them to enter the interior of the collection shell. When replacing the filter plate, the bottom of the filter plate is unlocked by rotating the bolts. Then, the fixed block is separated from the top of the filter plate by the flipping of the rotating plate, thus enabling the filter plate to be disassembled and assembled, thereby improving the flexibility of the filter plate.

[0007] As a further description of the above technical solution:

[0008] The impurity collection mechanism includes two locking plates, with adjacent sides of the two locking plates rotatably connected to the bottom left and right sides of the diversion chamber. Locking slots are provided on both the left and right sides of the collection shell, and the front side of each locking plate engages with the locking slot. Engaging posts are fixedly connected to the left and right rear ends of the collection shell. Engaging slots are provided at the bottom left and right front ends of the diversion chamber, and the rear side of each engaging post engages with the engaging slot. A drain valve is connected to the bottom of the collection shell, and an installation frame is fixedly installed in the middle of the collection shell. Multiple fixing grid plates are fixedly connected to the inner wall of the installation frame.

[0009] The above technical solution enables the unified collection of leaves and impurities through the connection of the fixed grid plate, and then the sewage is discharged through the drain valve. By rotating the locking plate, it can be unlocked from the left and right sides of the collection shell. At the same time, by pulling the collection shell, its rear side is released from the front side of the diversion chamber, which facilitates cleaning and maintenance.

[0010] As a further description of the above technical solution:

[0011] The impurity collection mechanism also includes a sealing ring, the inner wall of which is fixedly connected to the top of the outer wall of the drain valve.

[0012] The above technical solution improves the sealing effect between the drain valve and the bottom of the collection shell by connecting the sealing ring.

[0013] As a further description of the above technical solution:

[0014] Each of the two locking plates has a rubber ring fixedly connected to an adjacent side, and the outer sides of the two rubber rings respectively engage with the inner dimensions of the corresponding locking grooves.

[0015] The above technical solution improves the fixing effect of the locking plate by connecting the rubber ring.

[0016] As a further description of the above technical solution:

[0017] A handle is fixedly connected to the front side of the movable plate, and a rubber sleeve is fixedly connected to the middle of the handle.

[0018] The above technical solution improves the grip's anti-slip effect during use by connecting the rubber sleeve.

[0019] As a further description of the above technical solution:

[0020] The top of each of the two bolts is provided with a protective shell, and the rear side of each of the two protective shells is rotatably connected to the front bottom of the filter plate via a hinge.

[0021] The above technical solution enables the protective shell to protect the top of the bolt when connected.

[0022] As a further description of the above technical solution:

[0023] Both bolts are fixedly connected to the middle of a rubber ring, and both bolts are designed symmetrically.

[0024] The above technical solution reduces rotational damage to the front top of the filter plate caused by the bolts, thanks to the connection of the rubber ring.

[0025] As a further description of the above technical solution:

[0026] Two mounting bases are fixedly connected to the left and right sides of the diversion chamber, and the front side of the mounting base is provided with a mounting groove.

[0027] The above technical solution facilitates the installation and fixation of the structure by connecting the mounting base and the mounting slot.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the wastewater is collected by the diversion chamber, allowing the inclined filter plate to intercept leaves and impurities in the rainwater. This allows the leaves and impurities to enter the interior of the collection shell, thus avoiding the risk of pipe network blockage. The bottom of the filter plate is unlocked from the fixed shell by rotating the bolts. Then, the fixed block is separated from the top of the filter plate by flipping the rotating plate. The filter plate can be disassembled and assembled by pulling it, which improves the flexibility of the device.

[0030] 2. In this utility model, the connection between the mounting frame and the fixed grid plate enables the unified collection of leaves and impurities. Subsequently, the sewage can be discharged through the drain valve. Then, the locking plate can be flipped to unlock the collection shell, allowing the collection shell to be pulled apart so that its rear side separates from the front side of the diversion chamber, thus facilitating cleaning and maintenance and improving the service life of the device.

Rotating plates 5 are installed on the left and right ends of the front side of the mounting shell 4. The rotating plates 5 can rotate around their connection points by a rotating connection. The bottom of the rotating plates 5 is fixedly connected to a fixing block 6. At the same time, two fixing grooves 7 are opened in the middle of the top wall of the mounting shell 4 and the top of the front side of the filter plate 8. When the rotating plates 5 rotate, the fixing blocks 6 at their bottom can be correspondingly embedded into the fixing grooves 7 at the top of the mounting shell 4 and the filter plate 8. This engaging method achieves a stable fixation of the top of the filter plate 8. The inner wall of the diversion chamber 1 Two fixed shells 9 are fixedly connected to the front side of the middle section. The bottom of the filter plate 8 is adapted to and engaged with the top wall of the fixed shell 9, which further supports the filter plate 8.

Engaging grooves 203 are provided at the bottom left and right front ends of the diversion chamber 1. 04. Furthermore, the connection strength is improved by the engagement of the locking post 203 and the locking groove 204. The rear side of the locking post 203 engages with the locking groove 204. The bottom of the collection shell 16 is connected to a drain valve 205, through which sewage can be discharged. An installation frame 206 is fixedly installed in the middle of the collection shell 16. Through the connection between the installation frame 206 and the fixed grid plate 207, the unified collection of leaf impurities is completed. Multiple fixed grid plates 207 are fixedly connected to the inner wall of the installation frame 206.

[0042] Specifically, the two locking plates 201 are installed on the left and right bottom sides of the diversion chamber 1 by means of a rotatable connection, and can rotate around the connection point. Locking grooves 202 are correspondingly provided on the left and right sides of the collection shell 16. When it is necessary to fix the collection shell 16, the locking plate 201 is rotated so that its front side engages with the locking groove 202 on the collection shell 16. This engagement method achieves the initial fixed connection between the collection shell 16 and the diversion chamber 1. Engaging posts 203 are fixedly connected to the left and right rear ends of the collection shell 16. At the same time, engaging grooves 204 are correspondingly provided at the bottom of the left and right front ends of the diversion chamber 1. After the locking plates 201 and locking grooves 202 are engaged, the engaging posts 203 of the collection shell 16 are aligned with the engaging grooves 204 of the diversion chamber 1 and inserted, so that the rear of the engaging posts 203... The side engages with the locking groove 204, further improving the strength and stability of the connection between the collection shell 16 and the diversion chamber 1, ensuring that the collection shell 16 will not easily loosen or fall off during use. The bottom of the collection shell 16 is connected to a drain valve 205, which facilitates the cleaning of sewage inside the collection shell 16. An installation frame 206 is fixedly installed in the middle of the collection shell 16. Multiple fixed grid plates 207 are fixedly connected to the inner wall of the installation frame 206. These fixed grid plates 207 are parallel to each other and spaced apart to form a grid structure. During the impurity collection process, larger impurities such as leaves will be intercepted by the fixed grid plates 207, thereby achieving unified collection of leaf impurities and preventing leaves and other impurities from clogging the drain valve 205 or entering other pipes, ensuring the normal operation of the impurity collection mechanism 2 and smooth sewage discharge.

[0043] Reference Figure 1 , Figure 4 and Figure 5The impurity collection mechanism 2 also includes a sealing ring 208, the inner wall of which is fixedly connected to the top of the outer wall of the drain valve 205; rubber rings 209 are fixedly connected to adjacent sides of the two locking plates 201, and the outer sides of the two rubber rings 209 respectively engage with the inner dimensions of the corresponding locking grooves 202; a handle 14 is fixedly connected to the front side of the movable plate 13, and a rubber sleeve 15 is fixedly connected to the middle of the handle 14;

[0044] Specifically, the sealing effect between the drain valve 205 and the bottom of the collection shell 16 is improved by the connection of the sealing ring 208, the fixing effect between the locking plate 201 and the collection shell 16 is improved by the connection of the rubber ring 209, and the anti-slip effect of the handle 14 is improved by the connection of the rubber sleeve 15.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The top of each of the two bolts 10 is provided with a protective shell 12, and the rear side of each of the two protective shells 12 is rotatably connected to the bottom front side of the filter plate 8 via a hinge; a rubber ring 11 is fixedly connected to the middle of each of the two bolts 10, and the two bolts 10 are symmetrically designed; two mounting seats 17 are fixedly connected to the left and right sides of the diversion chamber 1, and the front side of the mounting seat 17 is provided with a mounting groove 18.

[0046] Specifically, the rotating connection of the protective shell 12 protects the top of the bolt 10, the connection of the rubber ring 11 reduces the rotational damage of the bottom of the bolt 10 to the front bottom of the filter plate 8, and the connection between the mounting base 17 and the mounting groove 18 facilitates the installation and fixing of the device.

[0047] Working principle: When in use, rainwater and sewage are mixed and collected by connecting the mixing pipe to the top of the diversion chamber 1. The inclined filter plate 8 can intercept leaves and impurities in the rainwater, allowing them to enter the collection shell 16 through the inclined design of the filter plate 8. The filtered water flows out through the bottom of the diversion chamber 1, thus avoiding the risk of pipe blockage. When replacing the filter plate 8, open the movable plate 13, and turn the bolt 10 to unlock the bottom of the filter plate 8 from the top of the fixed shell 9. Then flip the rotating plate 5 to separate the fixing block 6 at its bottom from the top of the filter plate 8, so that the filter plate 8 can be disassembled by pulling it, and vice versa, thus improving the flexibility of the device.

[0048] Furthermore, the connection between the mounting frame 206 and the fixed grid plate 207 allows the fixed grid plate 207 to collect leaves and impurities uniformly. Subsequently, the sewage attached to the leaves and impurities can be discharged through the drain valve 205. Then, the locking plate 201 is flipped to unlock it from the locking grooves 202 on the left and right sides of the collection shell 16. As a result, the collection shell 16 can be pulled, causing the fixed post 203 on its rear side to separate from the locking groove 204 on the front side of the diversion chamber 1. This facilitates the cleaning and maintenance of the collection shell 16, thereby improving the service life of the device.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
