Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically to a drainage device for municipal roads. Background Technology

[0002] Water supply and drainage systems are a type of urban public facility, referring to the pipes that discharge sewage and rainwater from buildings, as well as the underground channels that discharge sewage and rainwater from cities, factories, or villages. Appropriate drainage systems are often installed along municipal roads to ensure that the road conditions are suitable for normal passage.

[0003] For example, Chinese patent CN215483445U discloses a drainage device for municipal roads, including a mortar wall and a water passage disposed inside the mortar wall. A movable groove is formed in the middle of the side wall of the mortar wall, and a guide block is disposed inside the movable groove. A movable float is fixedly connected to one side of the guide block that is close to the other. A fixed plate is disposed above the movable float, and several equally spaced drainage holes are formed inside the fixed plate. A filling head is fixedly connected to the upper side of the movable float, directly opposite the drainage holes. Several drainage outlets are formed on the upper and lower sides of the movable float, and the drainage outlets are connected to the inside of the water passage. This utility model, by setting a movable float that can move up and down, can automatically seal the water passage from the outside when the water level inside the water passage is too high, thereby effectively preventing rainwater backflow into the water passage and ensuring environmental safety.

[0004] The aforementioned patent also has certain drawbacks. While it achieves the sealing of the water passage from the outside world, thus effectively preventing rainwater from flowing back into the passage, the rainwater carries a large amount of garbage, including gravel and plastic bags, which can easily clog the filter opening of the uppermost filter plate, thus preventing a large amount of water from being discharged quickly.

[0008] Furthermore, two support blocks are fixed to the upper surface of the support frame and slidably connected inside the rotating plate. The cross-sectional shape of the two support blocks is T-shaped.

[0009] Furthermore, a sealing ring that fits against the rotating plate is fixed inside the sealed box, and a connecting groove for the connecting plate to be inserted is provided on the upper surface of the filter plate.

[0010] Furthermore, the length of the rotating plate is greater than the length of the support frame, and the cross-sectional shape of the support frame is U-shaped.

[0011] Furthermore, the filter plate has a threaded groove inside for the fixing screw to be threadedly connected, and the upper surface of the connecting plate has a threaded hole for the fixing screw to pass through, and the fixing screw is threadedly connected to the connecting plate through the threaded hole.

[0012] Furthermore, the shielding mechanism includes two floats slidably connected inside the filter plate, a float plate located on the upper side of the filter plate is fixed on the upper surface of the two floats, a positioning block is fixed on the opposite side of the two floats, a positioning rod is slidably connected inside the positioning block is fixed inside the filter box, and a limiting spring located outside the positioning rod is fixed on the upper surface of the positioning block.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This embodiment of a municipal road water supply and drainage device includes a ground surface 5, a filter plate 2 slidably connected inside the ground surface 5, a filter box 3 fixed on the lower surface of the filter plate 2, an anti-clogging mechanism 1 for preventing blockage inside the filter plate 2, and a shielding mechanism 4 for preventing the escape of malodorous gases inside the filter plate 2. All electrical components mentioned in this document are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer for control, and existing publicly disclosed power connection technologies are not described in detail in this document.

[0024] Please see Figure 2To prevent plastic bags and pebbles from clogging the filter opening, the anti-clogging mechanism 1 in this embodiment includes two connecting plates 107 inserted inside the filter plate 2. Each of the two connecting plates 107 has a screw 106 threaded inside. A support frame 104 is fixed to the upper surface of the two connecting plates 107. Wire mesh 105, which is in contact with the filter plate 2, is fixed to both the front and back of the support frame 104. A sealing box 102 is fixed to the upper surface of the support frame 104. A drive motor 101 is fixed to the bottom wall of the inner cavity of the sealing box 102. A rotating plate 103 is fixed to the outer side of the output shaft of the drive motor 101. Two cleaning rods 109 are fixed to the lower surface of the rotating plate 103. Steel brushes 108, which are in contact with the wire mesh 105, are fixed to the opposite side of each of the two cleaning rods 109. The hardness of the steel brushes 108 allows them to brush away plastic bags or cloth bags.

[0025] The drive motor 101 drives the rotating plate 103 to rotate via the output shaft. As the rotating plate 103 rotates, it drives the steel brush 108 to rotate via the two cleaning rods 109. The steel brush 108 cleans away the plastic bag covering the wire mesh 105 to prevent it from affecting the flow of water.

[0026] In this embodiment, two support blocks are fixed to the upper surface of the support frame 104 and slidably connected inside the rotating plate 103. The cross-sectional shape of the two support blocks is T-shaped. A sealing ring that fits against the rotating plate 103 is fixed inside the sealing box 102. A connecting groove for the connecting plate 107 to be inserted is opened on the upper surface of the filter plate 2. The length of the rotating plate 103 is greater than the length of the support frame 104. The cross-sectional shape of the support frame 104 is U-shaped. A threaded groove for the fixing screw 106 to be threadedly connected is opened inside the filter plate 2. A threaded hole for the fixing screw 106 to pass through is opened on the upper surface of the connecting plate 107. The fixing screw 106 is threadedly connected to the connecting plate 107 through the threaded hole. The control method of this application is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0027] It should be noted that the anti-blocking mechanism 1 uses wire mesh 105 to block stones and plastic bags carried in the water flow during drainage, which can clog the filter opening. At the same time, the drive motor 101, sealing box 101, rotating plate 103, steel brush 108 and cleaning rod 109 work together to clean up the garbage near the wire mesh 105 and the garbage attached to the wire mesh 105, preventing this garbage from affecting the water flow rate and thus ensuring smooth drainage.

[0028] Please see Figure 3-4To prevent the sludge accumulated in the drainage channel from emitting a large amount of foul odor, the shielding mechanism 4 in this embodiment includes two floats 402 slidably connected inside the filter plate 2. A float plate 401 located on the upper side of the filter plate 2 is fixed on the upper surface of the two floats 402, and a sealing plate is fixed on the lower surface of the float plate 401. A positioning block 405 is fixed on the opposite side of each of the two floats 402. The positioning block 405 is made of the same material as the float plate 401 to reduce the impact on the upward floating of the float plate 401. A positioning rod 404 slidably connected inside the positioning block 405 is fixed inside the filter box 3. A limiting spring 403 located outside the positioning rod 404 is fixed on the upper surface of the positioning block 405. The limiting spring 403 is a spring with low stiffness to avoid the spring stiffness being too large and causing a large impact on the upward floating distance of the float plate 401.

[0029] In this embodiment, the upper surface of the positioning block 405 is provided with a positioning hole through which the positioning rod 404 passes, and the positioning rod 404 is slidably connected to the positioning block 405 through the positioning hole. The left and right side walls of the inner cavity of the filter box 3 are provided with positioning grooves for the positioning block 405 to be slidably connected. The upper surface of the filter plate 2 is provided with a through hole for the float rod 402 to communicate with, and the float rod 402 is slidably connected to the filter plate 2 through the through hole.

[0030] It should be noted that the barrier mechanism 4, through the cooperation of the float plate 401, float rod 402, limit spring 403, positioning rod 404 and positioning block 405, allows water to be easily discharged into the sewer when draining, and at the same time, when not draining, it completely seals the filter openings on the filter plate 2 to prevent the foul odor released by the sludge accumulated in the sewer from being released upward and polluting the environment.

[0031] The working principle of the above embodiments is as follows:

[0032] (1) When draining, the water flows through the mesh of the wire mesh 105 to the filter plate 2, and then through the filter port on the filter plate 2 to the drain channel. At the same time, the wire mesh 105 blocks stones and plastic bags that are easy to clog the filter port. Then, the drive motor 101 is started. The drive motor 101 drives the rotating plate 103 to rotate through the output shaft. While the rotating plate 103 is rotating, the steel brush 108 is driven to rotate through the two cleaning rods 109. The steel brush 108 cleans the plastic bags covering the wire mesh 105 to prevent them from affecting the flow of water. The anti-clogging mechanism 1 blocks stones and plastic bags that can clog the filter port carried in the water flow during drainage through the wire mesh 105. At the same time, the drive motor 101, the sealing box 101, the rotating plate 103, the steel brush 108 and the cleaning rods 109 work together to clean the garbage near the wire mesh 105 and the garbage attached to the wire mesh 105, preventing these garbage from affecting the flow rate of water, thereby ensuring the smooth drainage.

[0033] (2) During drainage, the float 401 moves upward with the buoyancy of the water flow. At the same time, the two floats 402 drive the two positioning blocks 405 to slide upward together. As the positioning blocks 405 slide upward along the positioning rods 404, they compress the limiting springs 403. Different water flow sizes result in different buoyancy forces on the float 401. Under different buoyancy forces, the float 401 rises to different heights, thus opening gaps of different sizes to allow the water to drain smoothly. After drainage is completed, the limiting springs 403 push downward with the rebound force. The positioning block 405 moves the float 402 downwards, and the float plate 401 moves upwards with the float 402 until it is in contact with the filter plate 2. The blocking mechanism 4, through the cooperation of the float plate 401, float 402, limit spring 403, positioning rod 404 and positioning block 405, allows the water to be easily discharged into the sewer when draining, and at the same time, when not draining, it seals all the filter openings on the filter plate 2 to prevent the foul odor gas released by the sludge accumulated in the sewer from being released upwards and polluting the environment.
