Description

Technical Field

[0001] This utility model relates to the field of sewage filtration fence technology, specifically a foldable temporary sewage filtration fence. Background Technology

[0002] Wastewater filter barriers are an indispensable basic piece of equipment in wastewater treatment processes, widely used in municipal sewage networks, industrial wastewater treatment plants, rural wastewater treatment facilities, and the pretreatment stages of wastewater at various construction sites. Their main function is to effectively intercept and remove larger floating objects and suspended impurities, such as branches, plastic products, fabrics, and silt, from wastewater before it enters subsequent treatment units. This pretreatment method effectively prevents blockages or wear on subsequent pumps, pipes, and treatment equipment, thereby ensuring the stable and efficient operation of the entire wastewater treatment system and laying a solid foundation for advanced treatment processes.

[0003] However, existing wastewater filter fences have some shortcomings in terms of structure and use. Traditional filter fences typically consist of a fixed frame, filter grid, and connectors. Most of these components are rigid structures with relatively fixed connection methods, leading to two main problems: First, due to their rigid and non-foldable overall structure, traditional fences occupy a large storage space when not in use and are extremely inconvenient to transport and relocate to different work sites, increasing logistics costs and manpower burden. Second, when multiple fences need to be assembled to accommodate waterways of different widths or lengths, traditional products often use welding or complex bolt fixing methods for connection. This connection method is not only time-consuming and labor-intensive to install and disassemble, but also difficult to adjust once assembled, failing to flexibly adapt to changes in the site environment and exhibiting poor versatility. Therefore, developing a temporary wastewater filter fence that is structurally easy to fold and assemble, thereby improving portability, storage efficiency, and on-site deployment flexibility, is a technical problem urgently needing to be solved in this field. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable temporary sewage filter fence to solve the problems mentioned in the background art. Traditional sewage filter fences are usually composed of a frame, filter rack and fasteners. The frame and grid of traditional sewage filter fences are mostly rigid structures and the connection method is relatively fixed. Therefore, they are not convenient to fold and store. If they need to be moved or stored, they often require a large space and are relatively difficult to transport. In addition, traditional sewage filter fences are connected by welding and other fixing methods when splicing, which is inconvenient to disassemble and has poor flexibility.

[0005] This utility model discloses a foldable temporary sewage filter fence, including a fixed base plate, two fixed vertical plates fixed on the fixed base plate, a fixed horizontal axis fixed between the two fixed vertical plates, a first water-blocking frame rotatably mounted on the fixed horizontal axis, an installation groove opened on one side of the first water-blocking frame, and a second water-blocking frame rotatably connected to the top of the first water-blocking frame via a connecting hinge, a sliding ring seat and a return spring movably mounted on the fixed horizontal axis, the sliding ring seat being rotatable around the fixed horizontal axis, the sliding ring seat and the return spring being accommodated in the installation groove, an operating handle fixedly connected to the sliding ring seat, and the two ends of the return spring respectively abutting against the side wall of the installation groove and one side of the sliding ring seat; at least one positioning rod is fixedly provided on the sliding ring seat, the positioning rod being away from the return spring, the positioning rod extending and penetrating the first water-blocking frame, and selectively inserted into the fixed vertical plate corresponding to its position.

[0006] Preferably, a filter frame is fixedly connected to the front of both the first and second water-blocking frames.

[0007] Preferably, the splicing assembly includes a plug plate fixed to one side of the first and second water-blocking frames, and a plug hole on the other side that matches the plug plate.

[0008] Preferably, the splicing assembly further includes a connecting screw that can pass through the insertion hole and be threadedly connected to the insertion plate of the adjacent fence.

[0009] Preferably, it further includes a stabilizing waterproof component, which includes a support plate and a water baffle fixed to the bottom of the second water baffle, and a support groove and a mating groove respectively opened at the top of the first water baffle to match the support plate and the water baffle.

[0010] Preferably, a waterproof pad is fixedly connected to the front of the water baffle.

[0011] Preferably, the fixed base plate is provided with a bottom sealing plate, and the bottom sealing plate has an arc-shaped groove that matches the bottom edge contour of the first water baffle.

[0012] Preferably, the bottom ends of both sides of the first water baffle are provided with mounting arc grooves, and the lower part of the fixed vertical plate is movably connected to the mounting arc grooves.

[0013] Preferably, at least two threaded tubes are symmetrically embedded in the fixed base plate, and a positioning screw is threaded into the threaded tube.

[0014] Preferably, the inner side of the fixed vertical plate is provided with a positioning hole that cooperates with the positioning rod.

[0015] The beneficial effects of this utility model are as follows: By setting a connecting hinge between the upper and lower sections of the water-blocking frame, and cooperating with the rotatable connection between the lower water-blocking frame and the fixed base, the entire filter fence can achieve convenient two-section folding. Compared with the traditional rigid integrated structure, this design significantly reduces the volume after folding, greatly saving storage space and significantly reducing the difficulty and cost of transportation and on-site handling. In addition, its ingenious structural design, through the setting of a unique angle positioning component, allows the operator to easily unlock the water-blocking frame from the locked state by simply turning the operating handle to drive the sliding part and positioning rod. After adjusting to the required angle, the return spring can automatically push the positioning rod into the corresponding positioning hole, achieving quick and reliable locking and ensuring the structural stability of the device in both working and storage states. At the same time, the device supports modular splicing. The splicing components consisting of plug plates, plug holes, and connecting screws on both sides allow multiple independent fence units to be quickly and easily connected laterally to adapt to the waterway interception needs of different widths, greatly enhancing the product's versatility and on-site deployment flexibility. Finally, this utility model also demonstrates superior sealing performance. It not only features an arc-shaped groove at the fixed base plate that matches the bottom edge of the water baffle, but also a stable waterproof component consisting of a support plate, a water baffle plate, and a waterproof pad at the joint after the two sections of the water baffle are unfolded. These precise sealing structures effectively prevent sewage from leaking from the bottom of the device or the joint gaps, ensuring that all sewage can be treated through the filter frame, thereby guaranteeing excellent filtration results.

[0026] like Figure 1-7 As shown, this utility model provides a foldable temporary sewage filter fence, including a fixed base plate 1. Fixed vertical plates 2 are fixedly connected to the top of both sides of the fixed base plate 1. A fixed horizontal shaft 4 is fixedly mounted between the two fixed vertical plates 2. A first water-blocking frame 8 is rotatably connected to the outside of the fixed horizontal shaft 4. The bottom of the first water-blocking frame 8 is a semi-circular solid structure. The first water-blocking frame 8 is a rectangular frame in general. Installation arc grooves 7 are opened on both bottom sides of the first water-blocking frame 8. A bottom sealing plate 3 is fixedly connected to the top of the front of the fixed base plate 1. An installation groove 19 is opened on one corner of the bottom of the first water-blocking frame 8. After the installation groove 19 is opened, a certain thickness is left on one side of the first water-blocking frame 8. The transmission connection is equipped with an angle positioning component. The top front of the first water baffle 8 is rotatably connected to the second water baffle 9 via a connecting hinge 15. The front of both the first water baffle 8 and the second water baffle 9 is fixedly connected to a filter frame 10 via fixing bolts. The front of the first water baffle 8 and the second water baffle 9 is fitted with a rectangular groove that matches the filter frame 10. The fixing bolts pass through the filter frame 10 and the first water baffle 8 and the second water baffle 9 and are threaded together. The two sides of the first water baffle 8 and the second water baffle 9 are fixedly connected with splicing components. The ends of the first water baffle 8 and the second water baffle 9 that are close to each other are fitted with a stable waterproof component. The top surface of the fixed base plate 1 is symmetrically fixedly connected with a fixing component.

[0027] Furthermore, the fixed vertical plate 2 and the mounting arc groove 7 are matched and the fixed vertical plate 2 is movably connected inside the mounting arc groove 7. The bottom sealing plate 3 has an arc-shaped groove matching the surface of the first water baffle 8 on the side near the first water baffle 8, forming a relatively sealed structure to prevent solid impurities in sewage from passing through.

[0028] Furthermore, the angle positioning component includes a return spring 20, which is movably sleeved on the outside of the fixed horizontal shaft 4. One end of the return spring 20 contacts the side wall of the mounting groove 19. A sliding ring seat 21 is movably connected inside the mounting groove 19. The sliding ring seat 21 is movably sleeved on the outside of the fixed horizontal shaft 4. One side of the sliding ring seat 21 contacts the other end of the return spring 20. An operating handle 23 is fixedly connected to the middle of the outer side of the sliding ring seat 21. Multiple positioning rods 22 (or one positioning rod 22) are fixedly connected at equal angles on the side of the sliding ring seat 21 away from the return spring 20. The first water baffle 8 and the fixed vertical plate 2 are respectively provided with multiple holes that cooperate with the positioning rods 22. The shape of the holes corresponds to the shape of the positioning rods 22. The multiple holes are relative to the positioning rods 22. The first water baffle 8 is arranged symmetrically along the central axis. The positioning rod 22 extends through the first water baffle 8 and the corresponding fixed vertical plate 2. When it is necessary to adjust the angle of the first water baffle 8, the operating handle 23 is turned to move the sliding ring seat 21 in the direction of compression of the return spring 20, and the positioning rod 22 is withdrawn from the fixed vertical plate 2, so that the first water baffle 8 is not restricted by rotation. Then the first water baffle 8 is turned to rotate along the fixed horizontal axis 4 until it is adjusted to a relatively suitable angle. Then the operating handle 23 is turned in the opposite direction to move the sliding ring seat 21 in the direction of extension of the return spring 20, and the positioning rod 22 is inserted into the fixed vertical plate 2. The inner side of the fixed vertical plate 2 has a hole that cooperates with the positioning rod 22 to limit the position of the first water baffle 8.

[0029] Furthermore, the splicing assembly includes two plug-in plates 11, which are fixedly connected to one side of the first water-blocking frame 8 and the second water-blocking frame 9, respectively. The other side of the first water-blocking frame 8 and the second water-blocking frame 9 are provided with mating holes corresponding to their positions. The top plate of the first water-blocking frame 8 and the bottom plate of the second water-blocking frame 9 are threadedly connected with connecting screws 24, which are matched with the plug-in holes 12. When multiple sets of first water-blocking frames 8 and second water-blocking frames 9 need to be spliced, the different sets of first water-blocking frames 8 and second water-blocking frames 9 are horizontally spliced ​​together. The plug-in plates 11 on the first water-blocking frame 8 and the second water-blocking frame 9 are inserted into the mating holes of another set of first water-blocking frames 8 and second water-blocking frames 9, and then the connecting screws 24 are screwed into the top plate of the first water-blocking frame 8 and the bottom plate of the second water-blocking frame 9 through the plug-in plates 11.

[0030] Furthermore, the stable waterproof component includes a support plate 13, which is fixedly connected to one side of the bottom of the second water-blocking frame 9. A water-blocking plate 17 is fixedly connected to the other side of the bottom of the mounting groove 19. A waterproof pad 18 is fixedly connected to the front of the water-blocking plate 17. The top of the first water-blocking frame 8 is respectively provided with a mating groove 16 and a support groove 14. The mating groove 16 and the support groove 14 are matched with the water-blocking plate 17 and the support plate 13, respectively. When the first water-blocking frame 8 and the second water-blocking frame 9 are unfolded, the second water-blocking frame 9 is moved, causing the second water-blocking frame 9 to rotate under the action of the connecting hinge 15. With the rotation of the second water-blocking frame 9, the support plate 13 enters the interior of the support groove 14, the water-blocking plate 17 enters the interior of the mating groove 16, and the waterproof pad 18 contacts and connects with the groove wall of the mating groove 16, further enhancing the waterproof effect.

[0031] Furthermore, the fixing component includes two threaded tubes 5, which are symmetrically embedded inside the fixing base plate 1. The two threaded tubes 5 are threadedly connected to positioning screws 6. When fixing the fixing base plate 1, the fixing base plate 1 is placed in a suitable position, and a drilling tool is used to drill holes at the positions corresponding to the positioning screws 6. Then, the positioning screws 6 are screwed into the holes to fix the fixing base plate 1, thereby fixing the entire device.
