Description

Technical Field

[0001] This utility model relates to the field of fiberglass cover technology, specifically to a high-strength, well-sealed circular fiberglass cover. Background Technology

[0002] In numerous industrial and civil applications, circular glass-fiber reinforced plastic (GRP or FRP) covers are widely used due to the material's lightweight, corrosion resistance, and excellent insulation properties. Covers are typically manufactured using hand lay-up or molding processes. Sometimes, to meet specific size or shape requirements, multiple covers may need to be joined together to cover a larger area.

[0003] Fiberglass reinforced plastic (FRP) covers are commonly used to cover and protect important facilities and equipment, such as storage tanks. Therefore, they need sufficient strength to withstand external pressure, impacts, and other forces to ensure the safe and reliable operation of these facilities and equipment. FRP covers are typically composed of multiple panels joined together, and to save space, they are usually hollow. The cross-section of the cover panel is curved, and the distance from bottom to top is relatively long. When connected with multiple covers, the lack of a support point in the middle of a single cover panel can cause it to crack under pressure, thus affecting the strength of the circular FRP cover. Utility Model Content

[0004] This invention proposes a high-strength, well-sealed circular fiberglass cover plate, which improves the strength of the circular fiberglass cover plate.

[0005] The technical solution of this utility model is as follows: a high-strength, well-sealed circular fiberglass cover plate, comprising a fiberglass cover plate, wherein the fiberglass cover plate comprises a plurality of cover plates, and a reinforcing block is fixedly connected to the inner side of each cover plate, and a sliding groove is provided on one side of each reinforcing block, and a connecting plate is connected in each sliding groove.

[0006] Furthermore, the connecting plate is provided with several through slots, and the through slots are arranged circumferentially around the connecting plate.

[0007] Furthermore, the top of the cover plate is provided with a sealing groove, the bottom of the sealing groove is provided with an installation groove, a sealing gasket is provided in the installation groove, and the inner wall of the sealing groove is provided with a threaded section and a sealing end cap is threadedly connected thereto.

[0008] Furthermore, one side of the cover plate is provided with a mounting block, the mounting block is provided with a positioning groove, and the other side of the cover plate is provided with a positioning block that engages with the positioning groove.

[0009] Furthermore, the bottom of the cover plate is provided with a threaded hole, and both sides of the threaded hole are provided with fixing grooves, and each fixing groove is provided with a fixing component for preventing the bolts from loosening.

[0010] Furthermore, the fixing component includes an elastic element and a fixing plate. One end of the elastic element abuts against the side of the fixing groove, and the other end of the elastic element abuts against the fixing plate. The fixing plate extends into the threaded hole, and the top of the fixing plate is provided with an inclined surface that is slidably connected to the bolt.

[0011] Furthermore, one side of the fixing plate extends into the threaded hole, the other side of the fixing plate slides into the fixing groove, and the end of the fixing plate away from the elastic element has an arc-shaped structure.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] This invention improves the stability and strength of individual cover plates by using reinforcing blocks, and connects multiple cover plates to enhance the overall strength of the fiberglass cover system. The connecting plates increase the connection strength between cover plates, making the entire structure more stable and enhancing the impact resistance of the fiberglass cover. When a cover plate is under pressure, the connecting plates distribute the stress evenly to each cover plate, preventing individual cover plates from cracking under load and thus improving the strength of the fiberglass cover.

[0014] The sliding grooves also help workers quickly position the cover plate, making the installation of the cover plate simpler and faster, and improving the installation efficiency of the workers. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] refer to Figure 1-6 A high-strength, well-sealed circular fiberglass cover plate includes a fiberglass cover plate, which includes several cover plates 1. Each cover plate 1 has a reinforcing block 101 fixedly connected to its inner side. The reinforcing block 101 is integrally formed with the cover plate 1, which can save costs. Each reinforcing block 101 has a groove 102 on one side, and each groove 102 is connected to a connecting plate 103.

[0025] The reinforcing block 101 improves the stability and strength of the individual cover plate 1, while the connecting plate 103 connects multiple cover plates 1, thereby increasing the strength of the entire fiberglass cover system. The connecting plate 103 increases the connection strength between the cover plates 1, making the entire structure more stable and enhancing the impact resistance of the fiberglass cover. When the cover plate is under pressure, the stress is evenly distributed to each cover plate through the connecting plate, thus preventing a single cover plate 1 from cracking under the weight, thereby improving the strength of the fiberglass cover.

[0026] Meanwhile, the sliding groove 102 provided in this embodiment can help the staff to quickly position the cover plate 1, making the installation of the cover plate 1 simpler and faster, and improving the installation efficiency of the staff. When the staff needs to assemble the circular fiberglass cover plate, the connecting plate 103 is fixed first, and then the inner wall of the sliding groove 102 on each cover plate 1 is brought into contact with the connecting plate 103 to achieve quick positioning. Finally, the adjacent cover plates 1 are fixed with bolts.

[0027] A plurality of through slots 104 can be provided on the connecting plate 103, and the plurality of through slots 104 are arranged circumferentially with the connecting plate 103 as the center. By providing through slots 104 on the connecting plate 103, the amount of material used can be reduced without sacrificing strength, thereby reducing the overall weight of the fiberglass structure, reducing the pressure on the bottom support structure of the fiberglass cover plate, and improving the service life of the support structure.

[0028] In this embodiment, in order to increase the sealing performance of the circular fiberglass cover plate, a sealing groove 105 is provided at the top of the cover plate 1, and an installation groove 106 is provided at the bottom of the sealing groove 105. A sealing gasket 107 is provided in the installation groove 106. The sealing gasket 107 is made of rubber because rubber has good elasticity and plasticity, which can effectively fill the joints, form a seal, and prevent gas leakage. Therefore, the sealing gasket 107 is preferably made of rubber. The inner wall of the sealing groove 105 is provided with a threaded section and a sealing end cap is threadedly connected to it.

[0029] When workers assemble several cover plates 1 into a circular fiberglass cover, a sealing gasket 107 is placed in the mounting groove 106 to seal the top of the circular fiberglass cover. One side of the sealing gasket 107 should extend into the sealing groove 105. Since the sealing gasket 107 is compressible, when the sealing groove 105 is sealed with the sealing end cap 108, the sealing gasket 107 can be compressed, resulting in a better sealing effect. The sealing end cap 108 is threaded into the sealing groove 105, ensuring that the sealing end cap 108 fits tightly against the top of the fiberglass, thereby providing a more reliable sealing effect and preventing moisture, dust, and other debris from entering the structure. At the same time, the threaded connection makes it easier to install the sealing end cap 108 on the top of the circular fiberglass cover, reducing the need for additional tools or equipment during installation and improving installation efficiency.

[0030] In this embodiment, a mounting block 2 is provided on one side of the cover plate 1, and a positioning groove 201 is provided in the mounting block 2. A positioning block 202 is provided on the other side of the cover plate 1, which engages with the positioning groove 201. By setting the positioning block 202 and the positioning groove 201, the contact area between two adjacent cover plates 1 can be increased, thereby improving the sealing effect. At the same time, the positioning block 202 and the positioning groove 201 can quickly help workers to combine two adjacent cover plates 1, improving the efficiency of workers in installing circular fiberglass cover plates.

[0031] In this embodiment, the circular fiberglass cover plate is usually fixed to the support structure with bolts. In order to solve the problem that the bolts will gradually loosen when the circular fiberglass cover plate is subjected to vibration, a threaded hole 3 is provided at the bottom of the cover plate 1. A fixing groove 301 is provided on both sides of the threaded hole 3. Each fixing groove 301 is provided with a fixing component to prevent the bolt from loosening. When the bolt is screwed into the threaded hole 3, the side of the bolt can be fixed by the fixing component, thereby preventing the bolt from gradually loosening due to vibration and improving the stability of the connection between the circular fiberglass cover plate and the support structure.

[0032] Specifically, the fixing components include an elastic element 302 and a fixing plate 303. The elastic element 302 is a cylindrical compression spring. One end of the elastic element 302 abuts against the side of the fixing groove 301, and the other end of the elastic element 302 abuts against the fixing plate 303. The fixing plate 303 extends into the threaded hole 3. The top of the fixing plate 303 is provided with an inclined surface 304 that slides with the bolt. When the operator screws the bolt into the threaded hole 3, the bottom of the thread will press against the top of the fixing plate 303, thereby causing the fixing plate 303 to move in the direction of compressing the elastic element 302. When the bolt is screwed to the bottom, the fixing plates 303 on both sides will clamp the sides of the bolt to prevent the thread from loosening. Through the elastic element 302, some of the vibration energy can be absorbed when the circular fiberglass cover is subjected to vibration, thereby improving the stability of the circular fiberglass cover.

[0033] Furthermore, one side of the fixing plate 303 extends into the threaded hole 3, and the other side of the fixing plate 303 is slidably connected to the inside of the fixing groove 301. The end of the fixing plate 303 away from the elastic element 302 has an arc-shaped structure. When the thread is tightened into the threaded hole 3 and the fixing plate 303 is squeezed, the fixing plate 303 will slide and connect with the inner wall of the fixing groove 301. The fixing groove 301 restricts the degree of freedom of the fixing plate 303, so that it can only move within the fixing groove 301, avoiding the fixing plate 303 from being squeezed out of the fixing groove 301 by the bolt, thus improving the stability of the fixing assembly. It can ensure that the elastic element 302 is subjected to uniform force and improve the service life of the elastic element 302. The arc-shaped structure of the end of the fixing plate 303 away from the elastic element 302 can increase the contact area between the fixing plate 303 and the bolt, thereby improving the fixing effect of the bolt. At the same time, the fixing assembly of this embodiment can be reused, improving practicality.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
