Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage device technology, and in particular to a municipal water supply and drainage device. Background Technology

[0002] As part of urban infrastructure, road drainage systems play an important role in removing urban rainwater and sewage, ensuring the smooth operation of the urban drainage system, and fall under the category of municipal water supply and drainage systems.

[0003] Chinese utility model patent with publication number CN221030562U discloses a municipal road water supply and drainage device, which includes a drainage ditch installed on both sides of the municipal road. The top of the drainage ditch is provided with an installation groove. Several buffer grooves are provided on the installation groove along both sides of the drainage ditch. A water grate is provided on the top of the drainage ditch. The water grate is connected to the installation groove. An installation block is provided at the bottom of the water grate. A damping spring shock absorber is fixedly connected to the bottom of the installation block. A buffer plate is fixedly installed at the bottom of the damping spring shock absorber. The buffer plate is connected to the buffer groove.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: When using the aforementioned technologies, multiple grates are installed in the drainage ditch, and filter frames are installed at the corresponding positions of the multiple grates. When the multiple filter frames are full of garbage, workers need to remove the multiple grates from the drainage ditch one by one before the filter frames can be removed and cleaned one by one. After cleaning the filter frames, the multiple grates also need to be placed back on the drainage ditch one by one. However, the grates themselves are quite heavy, making this method of operation inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a municipal water supply and drainage device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal water supply and drainage device, comprising a drainage ditch, a first drainage grate disposed within the drainage ditch, and a second drainage grate disposed within the drainage ditch. An installation groove is provided at the top of the drainage ditch, and both the first and second drainage grates cooperate with the installation groove. Multiple filter frames are disposed within the drainage ditch. A drainage pipe is fixed and connected to the side wall of the drainage ditch. An annular frame is fixed to the outer wall of each filter frame near its top. Filter frames are fixed to the inner walls on both sides of the drainage ditch. A horizontal plate overlaps at the bottom of the annular frame. A drive assembly is provided inside the drainage ditch to drive multiple filter frames toward the second drainage grate. The drive assembly includes an active rod rotatably mounted between the inner walls on both sides of the drainage ditch and a driven rod rotatably mounted between the inner walls on both sides of the drainage ditch. Synchronous pulleys are fixedly sleeved on both the active rod and the driven rod. The drive assembly also includes a synchronous belt that meshes with the synchronous pulleys on both the active rod and the driven rod. A partition is provided on the belt body on the upper side of the synchronous belt. Multiple partitions are alternately arranged with filter frames.

[0007] By adopting the above technical solution, when it is necessary to clean the garbage in the filter frame, the second drainage grate and the filter frame corresponding to the second drainage grate are first removed from the drainage channel. Then, the partition plate located near the second drainage grate is pulled towards the installation position of the second drainage grate. With the cooperation of two synchronous wheels, the driving rod and the driven rod, the synchronous belt fixed to the partition plate rotates, thereby causing the other partition plates on the synchronous belt to move towards the installation position of the second drainage grate. Since multiple partition plates and multiple filter frames are alternately arranged, the filter frames on the synchronous belt move sequentially to the installation position of the second drainage grate under the pushing action of the partition plates. At the same time, the annular frame slides along the top of the horizontal plate, and the staff can disassemble the filter frames one by one from the inside of the drainage channel. The entire process of disassembling the filter frames only requires opening the second drainage grate, which changes the cumbersome operation of the traditional technology that requires removing multiple drainage grates in sequence to remove the corresponding filter frames, making it more time-saving and labor-saving.

[0008] Furthermore, the partition has a T-shaped cross-section, the bottom of the vertical section of the partition is fixed to the belt body on the upper side of the synchronous belt, and the two sides of the horizontal section of the partition abut against the side walls of the two filter frames that are close to each other.

[0009] By adopting the above technical solution, when the synchronous belt rotates, since the two sides of the horizontal section of the partition abut against the side walls of the two filter frames that are close to each other, the partition will move with the filter frames during the rotation of the synchronous belt so as to remove the filter frames.

[0010] Furthermore, a ball bearing that is movably mounted at the bottom of the annular frame and is in rolling connection with the top of the horizontal plate is also provided.

[0011] By adopting the above technical solution, when the filter frame moves, the ball bearings make the horizontal plate and the annular frame move in a connected manner, reducing friction.

[0012] Furthermore, a first strip-shaped through hole is provided at the top of the vertical section of the partition near the second drainage grate.

[0013] By adopting the above technical solution, the setting of the first strip-shaped through hole makes it easier for workers to pull the partition and make the synchronous belt rotate.

[0014] Furthermore, two second strip-shaped through holes are provided at the top of the annular frame, and the two second strip-shaped through holes are symmetrically distributed on both sides of the annular frame.

[0015] By adopting the above technical solution, the two second strip-shaped through holes make it easier for workers to lift the ring frame and the filter frame.

[0016] Furthermore, a push plate is slidably disposed inside the filter frame, and multiple filter holes are disposed through the push plate.

[0017] Furthermore, a sliding rod is fixed to the bottom of the push plate, the sliding rod passes through the bottom of the filter box and is clearance-fitted, a limit block is fixed to the lower end of the sliding rod, and the diameter of the limit block is larger than the diameter of the sliding rod.

[0018] By adopting the above technical solution, when cleaning the garbage in the filter frame, the staff can push the push plate by sliding the rod, so that the push plate can clean the garbage stuck to the inner wall of the filter frame.

[0019] Furthermore, the height of the bottom wall of the drain pipe is less than the height of the bottom wall of the drain ditch.

[0020] By adopting the above technical solution, since the height of the bottom wall of the drain pipe is less than the height of the bottom wall of the drainage ditch, it is easier for the water in the drainage ditch to be discharged from the drain pipe.

[0021] In summary, this utility model has the following beneficial effects: When it is necessary to clean the garbage in the filter frame, first remove the second drainage grate and the filter frame corresponding to the second drainage grate from the inside of the drainage channel. Then, pull the partition plate located near the second drainage grate toward the installation position of the second drainage grate. With the cooperation of two synchronous wheels, the driving rod and the driven rod, the synchronous belt fixed to the partition plate rotates, thereby causing the other partition plates on the synchronous belt to move toward the installation position of the second drainage grate. Since multiple partition plates and multiple filter frames are alternately arranged, the filter frames on the synchronous belt move sequentially to the installation position of the second drainage grate under the pushing action of the partition plates. At the same time, the annular frame slides along the top of the horizontal plate, and the workers can disassemble the filter frames one by one from the inside of the drainage channel. The entire disassembly of the filter frames only requires opening the second drainage grate, which changes the cumbersome operation of the traditional technology that requires removing multiple drainage grates in sequence to remove the corresponding filter frames, making it more time-saving and labor-saving.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-6 As shown in the illustration, this application discloses a municipal water supply and drainage device, including a drainage channel 1, a first drainage grate 2, a second drainage grate 3, and a drive assembly 9. Both the first drainage grate 2 and the second drainage grate 3 are disposed within the drainage channel 1. An installation groove 4 is provided at the top of the drainage channel 1, and both the first drainage grate 2 and the second drainage grate 3 cooperate with the installation groove 4. A drainage pipe 6 is fixed to the side wall of the drainage channel 1, and the interior of the drainage pipe 6 is interconnected with the interior of the drainage channel 1. The height of the bottom wall of the drainage pipe 6 is less than the height of the bottom wall of the drainage channel 1. Multiple filter frames 5 are disposed within the drainage channel 1, and an annular frame 7 is fixed to the outer wall of each filter frame 5 near its top. Horizontal plates 8 are fixed to the inner walls on both sides of the drainage channel 1, and the tops of both horizontal plates 8 overlap with the bottom of the annular frame 7. A ball bearing 11 is movably mounted at the bottom of the annular frame 7, and the bottom of the ball bearing 11 is in rolling connection with the top of the horizontal plate 8.

[0031] A drive assembly 9 is installed inside the drainage ditch 1. The drive assembly 9 drives multiple filter frames 5 to move towards the second drainage grate 3. The drive assembly 9 includes a drive rod 91, a driven rod 92, a timing pulley 93, and a timing belt 94. The drive rod 91 and driven rod 92 are rotatably mounted between the inner walls on both sides of the drainage ditch 1, and are parallel to each other. Two timing pulleys 93 are provided; one is fixedly sleeved on the drive rod 91, and the other is fixedly sleeved on the driven rod 92. The timing belt 94 meshes with both the timing pulleys 93 on the drive rod 91 and the driven rod 92. A partition 10 is provided on the upper side of the timing belt 94. The partition 10 has a T-shaped cross-section, and the bottom of its vertical section is fixed to the top of the upper side of the timing belt 94. Multiple partitions 10 and filter frames 5 are alternately arranged, with the horizontal sections of the partitions 10 abutting against the adjacent side walls of two filter frames 5. When it is necessary to clean the debris inside the filter frame 5, first remove the second drainage grate 3 and the filter frame 5 corresponding to the second drainage grate 3 from the inside of the drainage channel 1. Then, pull the partition 10 located near the second drainage grate 3 toward the installation position of the second drainage grate 3. With the cooperation of the two synchronous pulleys 93, the driving rod 91 and the driven rod 92, the synchronous belt 94 fixed to the partition 10 rotates, thereby causing the other partitions 10 on the synchronous belt 94 to also move toward the installation position of the second drainage grate 3. Since multiple partitions 10 and multiple filter frames 5 are alternately arranged, the horizontal sections of the partitions 10 are respectively connected to two filter frames on both sides. The side walls of the two sides approach each other, causing the filter frames 5 on the synchronous belt 94 to move sequentially to the installation position of the second drainage grate 3 under the pushing action of the partition plate 10. At the same time, the annular frame 7 slides along the top of the horizontal plate 8 (because the ball bearing 11 is connected to the top of the horizontal plate 8 by rolling, the friction between the annular frame 7 and the horizontal plate 8 can be reduced, making it easier to pull). The workers can disassemble the filter frames 5 from the inside of the drainage channel 1 one by one. The entire disassembly of the filter frames 5 only requires opening the second drainage grate 3, which changes the cumbersome operation of the traditional technology that requires removing multiple drainage grates in sequence to remove the corresponding filter frames 5, making it more time-saving and labor-saving.

[0032] A first strip-shaped through hole 12 is provided on the top of the vertical section of the partition 10 near the second drainage grate 3. The first strip-shaped through hole 12 makes it easy for the operator to pull the partition 10 and make the synchronous belt 94 rotate.

[0033] Two second strip-shaped through holes 13 are provided at the top of the annular frame 7, and the two second strip-shaped through holes 13 are symmetrically distributed on both sides of the annular frame 7. The two second strip-shaped through holes 13 make it easy for workers to lift the filter frame 5 through the annular frame 7 to clean the debris inside the filter frame 5.

[0034] A push plate 14 is slidably mounted inside the filter frame 5, and multiple filter holes are provided through the push plate 14. A slide rod 15 is fixed to the bottom of the push plate 14, and the slide rod 15 passes through the bottom of the filter box and is clearance-fitted. A limit block 16 is fixed to the lower end of the slide rod 15, and the diameter of the limit block 16 is larger than the diameter of the slide rod 15. When cleaning the debris inside the filter frame 5, the operator can push the push plate 14 through the slide rod 15, so that the push plate 14 can clean the debris adhering to the inner wall of the filter frame 5.

[0035] The operating principle of a municipal water supply and drainage device in this embodiment is as follows: When it is necessary to clean the garbage in the filter frame 5, the second drainage grate 3 and the filter frame 5 corresponding to the second drainage grate 3 are first removed from the drainage channel 1. Then, the partition 10 located near the second drainage grate 3 is pulled toward the installation position of the second drainage grate 3. With the cooperation of the two synchronous wheels 93, the driving rod 91 and the driven rod 92, the synchronous belt 94 fixed to the partition 10 rotates, thereby causing the other partitions 10 on the synchronous belt 94 to also move toward the installation position of the second drainage grate 3. Since multiple partitions 10 and multiple filter frames 5 are alternately arranged, the horizontal of the partitions 10 is... The two sides of the section abut against the side walls of the two filter frames 5, which are close to each other. This allows the filter frames 5 on the synchronous belt 94 to move sequentially to the installation position of the second drainage grate 3 under the pushing action of the partition plate 10. At the same time, the annular frame 7 slides along the top of the horizontal plate 8 (because the ball bearing 11 is connected to the top of the horizontal plate 8 by rolling, the friction between the annular frame 7 and the horizontal plate 8 can be reduced, making it easier to pull). The workers can disassemble the filter frames 5 one by one from the inside of the drainage channel 1. The entire disassembly of the filter frames 5 only requires opening the second drainage grate 3, which changes the cumbersome operation of the traditional technology that requires removing multiple drainage grates in sequence to remove the corresponding filter frames 5, making it more time-saving and labor-saving.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
