Description

Technical Field

[0001] The utility model belongs to the technical field of sewage interception and drainage, in particular to a sewage interception and drainage rainwater well. Background Art

[0002] A sewage interception and drainage rainwater well is a special inspection well used in urban drainage systems. It is usually installed in the rainwater pipe system and is different from ordinary rainwater wells in structure and function. This type of rainwater well is equipped with a special sewage interception device to intercept and separate pollutants in rainwater.

[0003] Sewage interception and drainage rainwater wells use a sewage interception hanging basket to intercept sewage. The sewage interception hanging basket is usually installed at the water inlet or a specific location of the rainwater well. Its mesh size has certain specifications. When rainwater carries debris into the rainwater well, larger garbage such as plastic bags, branches, paper, etc. will be intercepted in the basket;

[0004] However, traditional rainwater wells typically use simple physical barriers to prevent backflow, such as fixed baffles or valves. While this approach can prevent backflow to a certain extent, it also presents challenges such as high structural complexity and inconvenient installation and maintenance. In particular, when pressure within the piping system fluctuates, these fixed baffles and valves may fail due to uneven force, rendering them ineffective in preventing backflow. Therefore, a novel rainwater well device with a simple structure, easy operation, and effective backflow prevention is proposed. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a sewage and rainwater interception and drainage well, which has a simple structure, is easy to operate and can effectively prevent backflow.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sewage interception and drainage rainwater well, comprising an outer ring, an inner ring disposed inside the outer ring, an anti-backflow mechanism disposed on the top of the inner ring, and connecting pipes disposed on both sides of the outer ring;

[0007] The anti-backflow mechanism includes a rotating sleeve, a rack block, a gear and a connecting rod. The rack block, gear and connecting rod are each provided in two numbers. The two rack blocks are respectively fixedly connected to the bottom surfaces at both ends of the rotating sleeve. The two gears are meshed and connected with the two rack blocks. One end of the two connecting rods is fixedly connected to the inner walls of the two gears, and a dual-axis motor is fixedly connected between the two connecting rods.

[0008] Preferably, a water seepage cover is installed on the top of the outer ring, a slot is provided inside the outer ring, and a basket is connected to the inner part of the outer ring through the slot, and the top surfaces around the basket are fixedly connected with pull rods.

[0009] Preferably, the top surface of the inner ring is fixedly connected to a fixing tube, the surface of the fixing tube is fixedly connected to a base, a fixing block is provided on the top of the base, and a rotating shaft is rotatably connected inside the fixing block.

[0010] Preferably, both ends of the rotating shaft pass through the fixed block and are fixedly connected with a blocking piece, and the outer wall of the rotating shaft is connected to the inner wall of the rotating sleeve.

[0011] Preferably, the rack block, gear and connecting rod are all located inside the base, the inner ring is connected to the fixed tube, and a flap door is fixedly connected to one side of the rotating sleeve.

[0012] Preferably, the size of the flap door is adapted to the size of the fixed tube, the two gears are located at the bottom of the two rack blocks, springs are fixedly connected on both sides of the dual-axis motor, one end of the spring is fixedly connected to a fixing plate, and one side of the fixing plate is connected to the inner wall of the base.

[0013] Preferably, one end of the connecting pipe is connected to the inner ring, a protective sleeve is provided on the outer surface of the connecting pipe, and a control valve is installed on the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model utilizes a seepage cover, a lifting basket, and a backflow prevention mechanism. When rainwater backflow prevention is required, a dual-axis motor is activated. The motor's rotational motion is transmitted to two gears via a connecting rod, causing the gears to rotate synchronously. Due to the meshing relationship between the gears and the rack blocks, the rotation of the gears drives the two rack blocks to move. The rack blocks are fixed to the bottom surfaces of both ends of the rotating sleeve. As a result, the rotating sleeve begins to move under the drive of the rack blocks. This movement of the rotating sleeve drives a flap door on one side of the rotating sleeve to move in a closing direction. Because the flap door is sized to fit the fixed pipe, it gradually closes the fixed pipe, preventing fluid from flowing back to the ground from the fixed pipe, thereby preventing fluid from backflowing into the upstream part of the system. The backflow prevention mechanism utilizes the dual-axis motor to drive the gears and rack blocks, driving the rotating sleeve to control the opening and closing of the flap door, effectively preventing liquid backflow and ensuring normal system operation. The utility model is particularly suitable for fluid transportation or processing scenarios with specific flow direction requirements. The springs and fixed plates on both sides of the dual-axis motor provide a buffering effect during motor operation, reducing vibration and noise. They also help stabilize the position of the motor and ensure the reliability and durability of the backflow prevention mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a sewage interception and drainage rainwater well, comprising an outer ring 1, an inner ring 2 is arranged inside the outer ring 1, an anti-backflow mechanism 3 is arranged on the top of the inner ring 2, and connecting pipes 4 are arranged on both sides of the outer ring 1;

[0024] The backflow prevention mechanism 3 includes a rotating sleeve 31, a rack block 32, a gear 33 and a connecting rod 34. There are two rack blocks 32, two gears 33 and two connecting rods 34. The two rack blocks 32 are respectively fixedly connected to the bottom surfaces of the two ends of the rotating sleeve 31. The two gears 33 are meshed and connected with the two rack blocks 32. One end of the two connecting rods 34 is fixedly connected to the inner walls of the two gears 33, and a dual-axis motor 35 is fixedly connected between the two connecting rods 34.

[0025] The above scheme is adopted: the outer ring 1 serves as the external support structure of the entire device, providing a storage and protection space for the internal inner ring 2, anti-backflow mechanism 3, basket 6 and other components. The connecting pipes 4 on both sides are used for the outflow of fluid, connecting the device with the external fluid delivery system. The inner ring 2 is one of the important channels for fluid flow, and is connected to the connecting pipe 4 to realize the transmission of fluid in the device. The anti-backflow mechanism 3 on the top can prevent the fluid from flowing in the opposite direction and ensure that the fluid flows in the predetermined direction. The fixed pipe 21 on the top surface of the inner ring 2 provides support for the installation of subsequent components. At the same time, the fixed pipe 21 also participates in the fluid delivery process.

[0026] like Figures 1 to 5 As shown, a water seepage cover 5 is installed on the top of the outer ring 1, a card slot is opened inside the outer ring 1, and a basket 6 is connected to the inside of the outer ring 1 through the card slot, and the top surfaces of the basket 6 are fixedly connected with pull rods, and the top surface of the inner ring 2 is fixedly connected with a fixed tube 21, and the surface of the fixed tube 21 is fixedly connected with a base 22, and a fixed block 23 is provided on the top of the base 22, and the interior of the fixed block 23 is rotatably connected with a rotating shaft 24, both ends of the rotating shaft 24 pass through the fixed block 23 and are fixedly connected with baffles, and the outer wall of the rotating shaft 24 is connected to the inner wall of the rotating sleeve 31.

[0027] The above scheme is adopted: the rotating sleeve 31 serves as the key moving component, and the flap door 36 on one side cooperates with the fixed tube 21 to realize the opening and closing control of the fixed tube 21 through its own rotation, thereby achieving the purpose of preventing backflow. It is connected to the rotating shaft 24 and receives power transmission to realize rotation. The rack block 32 (two): is respectively fixed to the bottom surface of the two ends of the rotating sleeve 31, meshing with the gear 33, converting the rotational motion of the dual-axis motor 35 into the linear motion of the rotating sleeve 31 (driven by the gear 33), which is one of the transmission links to realize the opening and closing of the flap door 36.

[0028] like Figures 1 to 5 As shown, the rack block 32, the gear 33 and the connecting rod 34 are all located inside the base 22, the inner ring 2 and the fixed tube 21 are connected through, and a flap door 36 is fixedly connected to one side of the rotating sleeve 31. The size of the flap door 36 is adapted to the size of the fixed tube 21. The two gears 33 are located at the bottom of the two rack blocks 32, and springs 351 are fixedly connected to both sides of the dual-axis motor 35. One end of the spring 351 is fixedly connected to a fixing plate 352, and one side of the fixing plate 352 is connected to the inner wall of the base 22. One end of the connecting pipe 4 is connected to the inner ring 2, and a protective cover is provided on the outer surface of the connecting pipe 4, and a control valve is installed on the connecting pipe 4.

[0029] The above scheme is adopted: Gear 33 (two): meshes with the rack block 32, rotates under the drive of the dual-axis motor 35, and transmits the power of the motor to the rack block 32. The design at the bottom of the two rack blocks 32 ensures the stability and accuracy of the transmission. The basket 6 is conveniently removed from the outer ring 1 through the pull rods on the top surfaces of the four sides and the card groove inside the outer ring 1. It is used to collect debris carried in the fluid, etc., to prevent it from entering other key components inside the device and affecting normal operation, and is convenient for centralized cleaning. The base 22 is located on the top of the fixed tube 21, and accommodates the components of the anti-backflow mechanism 3 inside, providing a stable installation environment for the normal operation of these components, and ensuring the relative position and transmission relationship between the components. The connecting pipe 4 is connected to the inner ring 2 to realize the connection between the device and the external fluid system. It is a channel for fluid in and out. The protective cover on the outer surface can prevent the connecting pipe 4 from external physical damage, corrosion, etc. The control valve is used to accurately control the flow and on-off of the fluid in the connecting pipe 4.

[0030] The working principle and usage process of the utility model are as follows: the control valve on the connecting pipe 4 is opened appropriately according to the system requirements, allowing the fluid to flow from the connecting pipe 4 on the side of the outer ring 1 into the inner ring 2. The water seepage cover 5 on the top of the outer ring 1 prevents the entry of foreign matter. The basket 6 is normally placed in the card slot, ready to intercept any foreign matter that may enter. The fluid flows from the bottom surface to the water seepage cover 5, passes through the basket 6, enters the inner ring 2, and then flows through the through channel between the inner ring 2 and the fixed pipe 21, and continues to flow to the fixed pipe 21.

[0031] When it is necessary to prevent rainwater from flowing back, the dual-axis motor 35 is started, and the rotation of the motor is transmitted to the two gears 33 through the connecting rod 34, so that the gears 33 rotate synchronously. Due to the meshing relationship between the gear 33 and the rack block 32, the rotation of the gear 33 drives the two rack blocks 32 to move. The rack blocks 32 are fixed to the bottom surfaces of both ends of the rotating sleeve 31. Therefore, the rotating sleeve 31 starts to move under the drive of the rack blocks 32. The movement of the rotating sleeve 31 drives the flap door 36 on one side thereof to move in the closing direction. Because the size of the flap door 36 is adapted to the fixed pipe 21, the flap door 36 gradually closes the fixed pipe 21, preventing the fluid from flowing back from the fixed pipe 21 to the ground, thereby preventing the fluid from flowing back into the upstream part of the system.

[0032] During the operation of the dual-axis motor 35, the springs 351 on both sides of the motor will be compressed or stretched with the slight displacement of the motor. The fixing plate 352 connected to one end of the spring 351 interacts with the inner wall of the base 22 to provide a buffer for the motor, reduce the impact of motor vibration on the entire device, and ensure the stable operation of the anti-backflow mechanism 3.
