Description

Technical Field

[0001] This utility model relates to the field of cover plate technology, and in particular to a lightweight resin cover plate. Background Technology

[0002] Resin covers are covers made of resin and fiber materials through a heat pressing process. Lightweight resin covers are characterized by low density, light weight, and high strength. They are widely used in applications where weight reduction is required while maintaining strength, such as rail transit, chemical industry, and municipal drainage projects.

[0003] Resin covers are commonly used to cover openings such as manhole covers and drainage ditches. These areas often need to withstand pressure from vehicles, pedestrians, and heavy machinery. To ensure that the covers do not deform or break under these pressures, their support capacity needs to be strengthened. At the same time, during drainage operations, debris such as fallen leaves tend to accumulate in the cover area. If the debris is not filtered, it can cause blockages in the drainage pipes, thereby reducing sewage discharge efficiency. Therefore, a new solution is needed to address this problem.

[0004] Therefore, those skilled in the art have provided a lightweight resin cover plate to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightweight resin cover. Compared to traditional lightweight resin covers, this lightweight resin cover has weight-reducing holes inside the cover to reduce the burden on the well body and surrounding structures. Reinforcing ribs are set inside the weight-reducing holes, and filler is filled around the reinforcing ribs to reduce the weight of the cover while increasing its load-bearing capacity. At the same time, a filter mechanism is set inside the drain pipe to intercept fallen leaves and other debris from the cover. A fixing clamp is set on the filter screen, and a snap-fit ​​hole is set on the support frame inside the drain pipe. When installing the filter screen, a spring drives the telescopic rod to retract, snapping the fixing clamp onto the support frame. The support frame supports the filter screen, thus facilitating the installation and removal of the filter screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A lightweight resin cover plate includes a cover plate and a drain pipe. Support frames are fixedly connected to the front and rear ends of the inner wall of the drain pipe. A filter mechanism is provided on the inner wall of the drain pipe, including a filter screen. Multiple square grooves are formed on the outer walls of the front and rear ends of the filter screen. Telescopic rods are fixedly connected to the inner walls of the square grooves near the middle of the drain pipe. Return springs are fitted onto the shafts of the telescopic rods. Fixing clamps are fixedly connected to the outer walls of the telescopic rods away from the middle of the drain pipe. Multiple weight-reducing holes are formed inside the cover plate, and multiple diagonal reinforcing ribs are fixedly connected to the inner bottom surfaces of the weight-reducing holes.

[0008] Through the above technical solution, the lightweight resin cover plate improves the load-bearing capacity by opening weight-reducing holes inside the cover plate and setting diagonal bracing ribs in the weight-reducing holes to support the cover plate. At the same time, a filter mechanism is set in the drain pipe to intercept falling debris, and the filter screen is fixed by the clamping of the fixing clamp and the support frame, which facilitates the disassembly and assembly of the filter mechanism.

[0009] Furthermore, the outer wall of the return spring on the side near the middle of the drain pipe is fixedly connected to the inner wall of the square groove, and the outer wall of the return spring on the side away from the middle of the drain pipe is fixedly connected to the fixing clamp.

[0010] Through the above technical solution, the reset spring is connected to the square groove and the fixing clamp, which facilitates the spring to drive the telescopic rod and the fixing clamp to retract and reset.

[0011] Furthermore, handles are fixedly connected to the inner walls of both sides of the filter screen;

[0012] The above technical solution provides a handle that makes it easier for workers to hold the filter, facilitating its transportation and installation.

[0013] Furthermore, the support frame has multiple snap-fit ​​holes at both its front and rear ends;

[0014] The above technical solution involves creating snap-fit ​​holes on the support frame to facilitate the snap-fit ​​connection between the fixing clamp and the support frame, thereby fixing the filter screen.

[0015] Furthermore, the fixing clamp is snapped into connection with the support frame;

[0016] With the above technical solution, after the snap-fit ​​hole is opened on the support frame, a hole is formed in the middle of the frame body. The fixing clamp is inserted into the hole and the clamp body is snapped onto the support frame, thereby completing the snap-fit ​​fixation.

[0017] Furthermore, the cover plate is fixedly connected to the upper surface of the drain pipe;

[0018] The above technical solution uses a cover plate to shield the drain pipe, preventing pedestrians or objects from falling into it and enhancing safety.

[0019] Furthermore, the upper surface of the cover plate is provided with multiple drainage holes;

[0020] The above technical solution allows for the installation of drainage holes to facilitate the diversion of road surface water into drainage pipes during rain.

[0021] Furthermore, the outer wall of the diagonal brace reinforcing rib is tightly fitted with filler;

[0022] By using the above technical solutions, the filling material can improve the load-bearing capacity and safety of the cover plate.

[0023] This utility model has the following beneficial effects:

[0024] This utility model proposes a lightweight resin cover plate. Compared with most existing lightweight resin cover plates, this lightweight resin cover plate reduces the burden on the well body and surrounding structures by opening weight-reducing holes inside the cover plate, thus extending its service life. At the same time, reinforcing ribs are set inside the weight-reducing holes, and filler is filled around the reinforcing ribs. This not only reduces the weight of the cover plate but also improves its load-bearing capacity, thereby enhancing the safety and durability of the cover plate.

[0025] This utility model proposes a lightweight resin cover plate, which, compared with most existing lightweight resin covers, intercepts fallen leaves and other debris by setting a filter mechanism inside the drain pipe. It also features a fixing clamp on the filter screen and snap-fit ​​holes on a support frame inside the drain pipe. When installing the filter screen, a spring retracts a telescopic rod, snapping the fixing clamp onto the support frame, which then supports the filter screen. Removing the filter screen involves reversing the clamping operation, thus facilitating the installation and removal of the filter screen. Attached Figure Description

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.

[0036] One embodiment of this utility model is provided:

[0037] Reference Figure 1 and Figure 2 The system includes a cover plate 1 and a drain pipe 3. The front and rear ends of the inner wall of the drain pipe 3 are fixedly connected to support frames 4. The inner wall of the drain pipe 3 is provided with a filter mechanism 6, which includes a filter screen 601. The outer walls of the front and rear ends of the filter screen 601 are provided with multiple square grooves 603. The inner walls of the square grooves 603 near the middle of the drain pipe 3 are fixedly connected to telescopic rods 604. The telescopic rods 604 are fitted with return springs 605. The outer walls of the telescopic rods 604 away from the middle of the drain pipe 3 are fixedly connected to fixing clamps 606. The inside of the cover plate 1 is provided with multiple weight-reducing holes 7. The inner bottom surface of the weight-reducing holes 7 is fixedly connected to multiple diagonal bracing ribs 8.

[0038] The lightweight resin cover plate improves the load-bearing capacity of the cover plate 1 by opening weight-reducing holes 7 inside the cover plate 1 and setting diagonal bracing ribs 8 inside the weight-reducing holes 7. At the same time, a filter mechanism 6 is set in the drain pipe 3 to intercept falling debris, and the filter screen 601 is fixed by the clamping of the fixing clamp 606 and the support frame 4, which facilitates the disassembly and assembly of the filter mechanism 6.

[0039] Reference Figure 3 and Figure 4The outer wall of the return spring 605 on the side closest to the middle of the drain pipe 3 is fixedly connected to the inner wall of the square groove 603, and the outer wall of the return spring 605 on the side furthest from the middle of the drain pipe 3 is fixedly connected to the fixing clamp 606. The connection between the return spring 605, the square groove 603, and the fixing clamp 606 facilitates the spring to drive the telescopic rod 604 and the fixing clamp 606 to retract and reset. The inner walls on both sides of the filter screen 601 are fixedly connected to handles 602. The handles 602 facilitate workers to hold the filter screen 601 and facilitate the transportation and installation of the filter screen 601.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The front and rear ends of the support frame 4 are provided with multiple snap-fit ​​holes 5. The snap-fit ​​holes 5 on the support frame 4 facilitate the snap-fit ​​connection between the fixing clamp 606 and the support frame 4, thereby fixing the filter screen 601. The fixing clamp 606 is snap-fit ​​connected to the support frame 4. After the snap-fit ​​holes 5 are opened, a hole is formed in the middle of the frame body of the support frame 4. The fixing clamp 606 extends into the hole and snaps its body onto the support frame 4, thereby completing the snap-fit ​​fixing.

[0041] Reference Figure 1 and Figure 5 The cover plate 1 is fixedly connected to the upper surface of the drain pipe 3. The cover plate 1 covers the drain pipe 3, which can prevent pedestrians or objects from falling into the drain pipe 3 and enhance safety. The upper surface of the cover plate 1 has multiple drainage holes 2. The drainage holes 2 facilitate the introduction of road surface water into the drain pipe 3 when it rains. The outer wall of the diagonal bracing rib 8 is tightly connected with filler 9. The filler 9 can improve the load-bearing capacity and safety of the cover plate 1.

[0042] Working principle: The cover plate 1 is fixedly connected to the drain pipe 3 by bolts. The cover plate 1 has multiple weight-reducing holes 7 inside, and the inner bottom surface of the weight-reducing holes 7 is provided with diagonal bracing ribs 8. The weight-reducing holes 7 are filled with filler 9. While reducing the weight of the cover plate 1, the load-bearing capacity of the cover plate 1 is improved by the reinforcing ribs and filler 9. When installing the filter mechanism 6 inside the drain pipe 3, the worker holds the handle 602 and puts the filter screen 601 into the drain pipe 3. Then, the worker holds the fixing clamp 606 and retracts it inward, locking the fixing clamp 606 into the locking hole 5 of the support frame 4, so that the fixing clamp 606 is locked with the support frame 4. Thus, the filter screen 601 is supported by the fixing clamp 606 and the telescopic rod 604. When removing the filter screen 601, the fixing clamp 606 is operated in reverse, which facilitates the disassembly and assembly of the filter screen 601.
