Abstract

This utility model discloses a sewage interception device for water supply and drainage, including a prefabricated component. A drain pipe is connected to the bottom of the prefabricated component, and an installation frame is set inside the prefabricated component. A sewage interception screen is fixedly connected inside the installation frame. This utility model utilizes a rotating sealing knob, which drives a screw to rotate, causing the screw to move upwards. The screw then drives a pushing component to move upwards, causing a rocker arm to lose downward pressure. The tension of a return spring causes a moving plate and a locking pin to move towards the screw, disengaging the locking pin from its slot. The moving plate then pushes the rocker arm to rotate. When the installation frame and the prefabricated component lose their fixation, the installation frame can be moved upwards to remove the sewage interception screen. The sewage interception screen is not moved by external impacts during installation, providing a highly efficient anti-clogging advantage. Since the sewage interception component is fixed inside the prefabricated component, the impact of water flow cannot cause the sewage interception screen to shake, improving the effectiveness of the sewage interception component.

Description

Technical Field

[0001] This utility model relates to the technical field of municipal road drainage equipment, specifically a sewage interception device for water supply and drainage. Background Technology

[0002] It consists of a set of parallel metal bars or screens to intercept larger floating and suspended objects in sewage, such as branches, plastic bags, and paper. Manually cleaned screens are often used in small sewage treatment plants or in situations with low flow rates. Workers need to manually clean the intercepted debris regularly to ensure the screen's continuous operation.

[0003] During water supply and drainage operations, interception devices are required. Traditional interception devices are placed directly inside the precast components. When water flows through the interception screen, the impact force of the water flow will cause the interception screen to shake, resulting in the interception screen shifting its position inside the precast component. Ultimately, this causes the interception screen to fail to filter impurities efficiently, reducing the effectiveness of the interception components. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a sewage interception device for water supply and drainage, which has the advantage of efficient anti-clogging. It solves the problem that the sewage interception component of the device is placed directly inside the prefabricated component. When water flows through the sewage interception screen, the impact force of the water flow causes the sewage interception screen to shake, resulting in the sewage interception screen shifting inside the prefabricated component. Ultimately, this leads to the sewage interception screen being unable to efficiently filter impurities, thus reducing the effectiveness of the sewage interception component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage interception device for water supply and drainage, comprising a prefabricated component, the bottom of which is connected to a drain pipe, an installation frame is provided inside the prefabricated component, a sewage interception screen is fixedly connected inside the installation frame, slots are provided on both sides of the inner wall of the prefabricated component, a locking pin is provided inside the slot, the inner side of the locking pin extends into the interior of the installation frame, and a control mechanism is fixedly connected inside the locking pin.

[0006] In a preferred embodiment of this utility model, the control mechanism includes a movable plate, which is fixedly connected to the inner side of the locking pin. A rocker arm is provided on the inner side of the movable plate. The bottom of the rocker arm is movably connected to the inside of the mounting frame. A pusher is provided on the top of the rocker arm. The top of the pusher arm is movably connected to a screw. The surface of the screw is threadedly connected to the inner wall of the mounting frame. A reset spring is fixedly connected to the inner side of the movable plate. A mounting block is fixedly connected to the inner side of the reset spring. The bottom of the mounting block is fixedly connected to the bottom of the inner wall of the mounting frame. A sealing knob is fixedly connected to the top of the screw.

[0007] As a preferred embodiment of this invention, the bottom of the intercepting screen is provided with a support rod assembly, the surface of which is fixedly connected to the inner wall of the mounting frame.

[0008] As a preferred embodiment of this invention, a spring is fixedly connected to the surface of the mounting block, and the surface of the spring is fixedly connected to the surface of the rocker.

[0009] As a preferred embodiment of this utility model, the movable plate is provided with a sliding rod inside, the surface of the sliding rod is fixedly connected to the inner wall of the mounting frame, and the other end of the sliding rod is fixedly connected to the surface of the mounting block.

[0010] As a preferred embodiment of this invention, the pusher has a vertical rod inside, and the surface of the vertical rod is fixedly connected to the inner wall of the mounting frame.

[0011] As a preferred embodiment of this invention, the surface of the rocker is movably connected to a pulley, and the surface of the pulley is in contact with the surface of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a rotating sealing knob, which drives the screw to rotate, causing the screw to move upwards. The screw then drives the pushing component to move upwards, causing the rocker plate to lose downward pressure. The tension of the return spring then drives the moving plate and the locking pin to move towards the side closer to the screw. The locking pin disengages from the slot, and the moving plate pushes the rocker plate to rotate. When the mounting frame and the prefabricated component lose their fixation, the mounting frame can be moved upwards to remove the intercepting screen. When the intercepting screen is installed, it will not be moved by external impacts, thus possessing the advantage of efficient anti-clogging. The intercepting component of this device is fixed inside the prefabricated component, preventing the impact of water flow from causing the intercepting screen to shake, thereby improving the effectiveness of the intercepting component.

[0014] 2. By setting up a control mechanism, this utility model can control the locking pin, avoiding the inability to control the locking pin during use and improving the effectiveness of the locking pin.

[0015] 3. By setting up a support rod assembly, this utility model can support the intercepting screen, preventing the screen from collapsing due to the weight of impurities after filtering them, thus improving the safety of the screen in use. Attached Figure Description

A sealing knob 77 is fixedly connected to the top of the screw 74.

[0024] As a technical optimization of this utility model, by setting the control mechanism 7, the locking pin 6 can be controlled, avoiding the inability to control the locking pin 6 during use, and improving the use effect of the locking pin 6.

[0025] refer to Figure 4 The bottom of the intercepting screen 4 is provided with a support rod assembly 8, and the surface of the support rod assembly 8 is fixedly connected to the inner wall of the mounting frame 3.

[0026] As a technical optimization of this utility model, by setting up the support rod group 8, the intercepting screen 4 can be supported, preventing the intercepting screen 4 from being crushed by the weight of the impurities after filtering them, thus improving the safety of the intercepting screen 4 in use.

[0027] refer to Figure 3 A spring 9 is fixedly connected to the surface of the mounting block 76, and the surface of the spring 9 is fixedly connected to the surface of the rocker 72.

[0028] As a technical optimization of this utility model, by setting a spring 9, the rocker 72 can be rotated in an auxiliary manner, so as to prevent the rocker 72 from failing to automatically reset after losing support, thereby improving the ease of use of the rocker 72.

[0029] refer to Figure 3 The movable plate 71 is provided with a slide rod 10 inside. The surface of the slide rod 10 is fixedly connected to the inner wall of the mounting frame 3, and the other end of the slide rod 10 is fixedly connected to the surface of the mounting block 76.

[0030] As a technical optimization of this utility model, by setting the slide bar 10, the moving plate 71 can slide stably, avoiding the shaking of the moving plate 71 during the sliding movement, which would cause the moving plate 71 to loosen, thus improving the sliding stability of the moving plate 71.

[0031] refer to Figure 3 The pusher 73 has a vertical rod 11 inside, and the surface of the vertical rod 11 is fixedly connected to the inner wall of the mounting frame 3.

[0035] The working principle and usage process of this utility model are as follows: In use, the installation frame 3 and the intercepting screen 4 are fixed inside the prefabricated part 1. When it is necessary to disassemble the intercepting screen 4 and the installation frame 3, rotate the sealing knob 77. The sealing knob 77 drives the screw 74 to rotate, and the screw 74 moves upward as a whole. The screw 74 drives the pushing part 73 to move upward, and the rocker plate 72 loses its downward pressure. Through the tension of the reset spring 75, the moving plate 71 and the locking pin 6 move to the side closer to the screw 74. The locking pin 6 exits the inside of the locking groove 5. The moving plate 71 pushes the rocker plate 72 to rotate. When the installation frame 3 and the prefabricated part 1 are no longer fixed, the installation frame 3 can be moved upward to remove the intercepting screen 4. When the intercepting screen 4 is installed, it will not be moved by external impact.

[0036] In summary, this wastewater interception device for water supply and drainage, through the coordinated use of prefabricated component 1, drainage pipe 2, mounting frame 3, wastewater interception screen 4, slot 5, locking pin 6, and control mechanism 7, solves the problem that the wastewater interception component of this device is directly placed inside the prefabricated component. When water flows through the wastewater interception screen, the impact force of the water flow causes the wastewater interception screen to shake, resulting in the wastewater interception screen shifting its position inside the prefabricated component. Ultimately, this leads to the wastewater interception screen being unable to efficiently filter impurities, reducing the effectiveness of the wastewater interception component.
