Description
Technical Field
[0001] This utility model relates to the field of through-hole cover technology, and in particular to a protective cover structure for pipeline openings. Background Technology
[0002] During the actual construction and daily use of water plants, numerous openings exist, primarily used for equipment maintenance and pipeline installation. However, current protective measures for these openings present many problems.
[0003] Typically, these openings are either left unprotected or simply covered with temporary covers. Without protection, the openings are completely open, allowing debris to easily fall through. If this debris falls into the water plant's equipment or pipelines, it can cause blockages, damage, disrupt the plant's normal operation, or even lead to safety accidents.
[0004] However, using temporary covers also has many drawbacks. The covers are easily displaced by external forces, such as vibrations caused by people walking or equipment moving, which may cause the covers to deviate from their original position and lose their protective function.

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0021] Example 1
[0022] like Figure 1-2 As shown, a pipeline orifice protective cover structure includes a first cover plate 1 and a second cover plate 2 that are spliced together. The first cover plate 1 has a first splicing part 3 on one side for splicing with the second cover plate 2, and the second cover plate 2 has a second splicing part 4 on one side for splicing with the first splicing part 3.
[0023] In this embodiment, the first cover plate 1 and the second cover plate 2 are joined together to form a cover plate structure for covering the through hole, which serves to block the through hole, prevent debris from falling from the hole, and protect the hole, protecting the equipment or structure such as the conduit inside the hole from interference and damage from external factors.
[0024] Furthermore, the first splicing part 3 includes a fixing block 5 protruding from one side edge of the first cover plate 1, and also includes a locking block 6 fixed to one end of the fixing block 5, wherein the width of the locking block 6 is greater than the width of the fixing block 5.
[0025] Furthermore, the second assembly part 4 includes a fixing groove 7 formed on the second cover plate 2 that matches the shape of the fixing block 5, and also includes a locking groove 8 formed at one end of the fixing groove 7 and communicating with the fixing groove 7, wherein the locking groove 8 matches the shape of the locking block 6.
[0026] Specifically, the fixing block 5, which is protruding and located on one side edge of the first cover plate 1, provides a fixed base position for the locking block 6, allowing the locking block 6 to accurately engage with the fixing groove 7 and the locking groove 8 in the second assembly part 4. The locking block 6 is fixed to one end of the fixing block 5, and its width is greater than the width of the fixing block 5. This size design allows the locking block 6 to tightly engage with the locking groove 8 in the second assembly part 4. When the first assembly part 3 and the second assembly part 4 are assembled, the locking block 6 engages in the locking groove 8, which plays a role in locking and reinforcing, preventing the first cover plate 1 and the second cover plate 2 from easily separating or shifting due to external forces after assembly. This ensures that the entire cover plate structure can remain stable during use, reliably cover the through hole opening, and perform its protective function.
[0027] Furthermore, the first cover plate 1 is provided with a first clearance groove 9, and the second cover plate 2 is provided with a second clearance groove 10 for joining with the first clearance groove 9 to form a perforation.
[0028] The perforation formed by the first clearance groove 9 and the second clearance groove 10 allows some conduits to pass through according to actual needs, while blocking and protecting other parts. This achieves flexible coverage and protection of the through hole, which not only meets the needs of some conduits to pass through, but also prevents debris from falling from the hole, thus improving the practicality and adaptability of the entire cover plate structure.
[0029] In some embodiments, the first clearance groove 9 may have the same shape as the second clearance groove 10, or they may have different shapes, to adapt to the exterior of conduits of different shapes.
[0030] Furthermore, the locking block 6 is a variable diameter component fixed to one end of the fixing block 5, and the first cover plate 1 is provided with at least one first splicing part 3, and the second cover plate 2 is provided with at least one second splicing part 4.
[0031] The working process and principle of this utility model are as follows:
[0032] Place the first cover plate 1 and the second cover plate 2 near the through hole opening that needs to be covered, respectively, to ensure that the first splicing part 3 on the first cover plate 1 and the second splicing part 4 on the second cover plate 2 are in a splicable state. At the same time, check the position of the first clearance groove 9 and the second clearance groove 10 so that they can be spliced to form a perforation that meets the requirements.
[0033] Align the first splicing part 3 on the first cover plate 1 with the second splicing part 4 on the second cover plate 2 so that the fixing block 5 can be smoothly engaged in the fixing groove 7. During the installation process, the engaging block 6 will gradually enter the engaging groove 8 along the vertical direction of the fixing groove 7. When the engaging block 6 is fully engaged in the engaging groove 8, the first cover plate 1 and the second cover plate 2 are spliced together and tightly connected to form an integral cover plate structure.
[0034] The assembly is achieved based on the shape matching and fit between the first assembly part 3 and the second assembly part 4. The fixing block 5 of the first assembly part 3 is inserted into the fixing groove 7 of the second assembly part 4, which plays a role in initial positioning. The tight engagement between the locking block 6 and the locking groove 8 plays a role in locking and reinforcing, preventing the first cover plate 1 and the second cover plate 2 from easily separating or shifting due to external forces after assembly, thereby ensuring the stability of the entire cover plate structure after assembly.
[0035] Example 2
[0036] like Figure 3-4 As shown, a pipeline orifice protective cover structure includes a first cover plate 1 and a second cover plate 2 that are spliced together. The first cover plate 1 has a first splicing part 3 on one side for splicing with the second cover plate 2, and the second cover plate 2 has a second splicing part 4 on one side for splicing with the first splicing part 3.
[0037] In this embodiment, the first cover plate 1 and the second cover plate 2 are joined together to form a cover plate structure for covering the through hole, which serves to block the through hole, prevent debris from falling from the hole, and protect the hole, protecting the equipment or structure such as the conduit inside the hole from interference and damage from external factors.
[0038] Furthermore, the first splicing part 3 includes a fixing block 5 protruding from one side edge of the first cover plate 1, and also includes a locking block 6 fixed to one end of the fixing block 5, wherein the width of the locking block 6 is greater than the width of the fixing block 5.
[0039] Furthermore, the second assembly part 4 includes a fixing groove 7 formed on the second cover plate 2 that matches the shape of the fixing block 5, and also includes a locking groove 8 formed at one end of the fixing groove 7 and communicating with the fixing groove 7, wherein the locking groove 8 matches the shape of the locking block 6.
[0040] Specifically, the fixing block 5, which is protruding and located on one side edge of the first cover plate 1, provides a fixed base position for the locking block 6, allowing the locking block 6 to accurately engage with the fixing groove 7 and the locking groove 8 in the second assembly part 4. The locking block 6 is fixed to one end of the fixing block 5, and its width is greater than the width of the fixing block 5. This size design allows the locking block 6 to tightly engage with the locking groove 8 in the second assembly part 4. When the first assembly part 3 and the second assembly part 4 are assembled, the locking block 6 engages in the locking groove 8, which plays a role in locking and reinforcing, preventing the first cover plate 1 and the second cover plate 2 from easily separating or shifting due to external forces after assembly. This ensures that the entire cover plate structure can remain stable during use, reliably cover the through hole opening, and perform its protective function.
[0041] In some embodiments, an anti-slip layer or an adhesive layer may be provided at the bottom of the first cover plate 1 or the second cover plate 2. The anti-slip layer may be made of a material such as rubber that can generate a large friction force when in contact with the ground, and the adhesive layer may be made of a material with adhesive properties.
[0042] Furthermore, the first cover plate 1 is provided with a first clearance groove 9, and the second cover plate 2 is provided with a second clearance groove 10 for joining with the first clearance groove 9 to form a perforation.
[0043] The perforation formed by the first clearance groove 9 and the second clearance groove 10 allows some conduits to pass through according to actual needs, while blocking and protecting other parts. This achieves flexible coverage and protection of the through hole, which not only meets the needs of some conduits to pass through, but also prevents debris from falling from the hole, thus improving the practicality and adaptability of the entire cover plate structure.
[0044] In some embodiments, the first clearance groove 9 may have the same shape as the second clearance groove 10, or they may have different shapes, to adapt to the exterior of conduits of different shapes.
[0045] Furthermore, the locking block 6 is a variable diameter component fixed to one end of the fixing block 5, and the first cover plate 1 is provided with at least one first splicing part 3, and the second cover plate 2 is provided with at least one second splicing part 4.
[0046] Furthermore, both the first cover plate 1 and the second cover plate 2 have an enclosure portion 11 at their bottom edges. The enclosure portions 11 on the first cover plate 1 and the second cover plate 2 are combined to form a component for fitting onto the protruding opening.
[0047] By providing the enclosure portion 11, the first cover plate 1 and the second cover plate 2 can be installed on some protruding openings, so that this through-hole cover plate structure can not only adapt to standard flat openings, but also handle uneven or specially shaped openings well.
[0048] In some embodiments, the ends of the two enclosure portions 11 are joined together. This can be achieved by providing magnetic attraction components at the ends to allow the ends to adhere to each other, thus enabling a stable connection between them. Alternatively, the enclosure portions 11 on both sides can be joined together by providing a joint similar to the first joining portion 3 and the second joining portion 4.
[0049] In some embodiments, an anti-slip layer may be provided at the bottom of the enclosure 11. This anti-slip layer may be made of a material such as rubber that can generate a large friction force when in contact with the ground.
