Description

Technical Field

[0001] The present application belongs to the field of manhole covers, and in particular, relates to a glass fiber reinforced waterproof manhole cover. Background Art

[0002] Water meter wells and valve wells do play an important role in the water supply network. They are not only used to install and protect key equipment such as water meters and valves, but also provide convenient access for inspection and maintenance. Prefabricated water meter wells have been widely used in water supply systems due to their standardized production, mass manufacturing and easy installation. Water meter wells usually consist of a well body and a well cover, and the well cover is usually directly installed on the well body. Since the well cover is directly exposed on the ground, the gap between the well cover and the well body often becomes a channel for water to enter the well body. When a large amount of water accumulates in the well body, it will cause direct damage to the equipment in the well, such as water meter instruments, electrical components, and water pipes. It can be seen that the sealing between the well cover and the well body is particularly important.

[0003] In the prior art, using rubber sealing rings to waterproof manhole covers and well bodies is a common method. Specifically, an embedding groove is provided in a prefabricated manhole cover or a prefabricated well body, and the rubber sealing ring is provided in the embedding groove. The portion of the rubber sealing ring higher than the embedding groove is squeezed and interfered with the manhole cover or the well body to achieve a waterproof effect. For scenarios where the manhole cover is flooded with water, it is often necessary to provide multiple layers of rubber sealing rings. Although this improves the waterproof effect, more embedding grooves will be provided in the manhole cover or the well body accordingly. The number of sealing ring layers that can be provided on the manhole cover or the well body is limited by the overall size of the manhole cover or the well body. More embedding grooves means complex processing and high cost, and too many embedding grooves can easily affect the structural strength of the manhole cover or the well body, and therefore they often need to be customized separately. It can be seen that the prior art needs to be further improved and enhanced. Utility Model Content

[0004] The utility model provides a glass fiber reinforced waterproof manhole cover to solve the problem that when the manhole cover and the well body are flooded, multiple layers of sealing rings need to be provided, and correspondingly multiple embedding grooves need to be opened in the manhole cover or the well body, which is complicated to process, has high cost and is easy to affect the structural strength of the manhole cover or the well body.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A glass fiber reinforced waterproof manhole cover comprises a manhole cover body, an outer side wall of the manhole cover body is provided with an annular groove, a sealing ring is embedded in the annular groove, the groove depth of the annular groove is equal to the ring width of the sealing ring, and the outer periphery of the sealing ring is provided with multiple layers of spaced annular water-blocking belts, the annular water-blocking belts are extended along the outer side of the sealing ring, and the annular water-blocking belts can be bent, and the bent annular water-blocking belts abut against the outer peripheral wall of the sealing ring and the inner wall of the manhole body to form multiple seals.

[0007] The glass fiber reinforced waterproof manhole cover of the utility model sets an annular groove with a depth equal to the width of the sealing ring, so that the sealing ring can be stably embedded in the annular groove, reducing the risk of damage caused by friction or external force. The seal relies on the annular water-blocking tape to be bent and abut against the outer peripheral wall of the sealing ring and the inner wall of the well body, thereby ensuring its long-term effective sealing performance. Although only one sealing ring is used, multiple layers of spaced annular water-blocking tapes are set on the outer periphery of the sealing ring and are able to be bent and abut against the inner wall of the well body, thereby achieving a multiple sealing effect. While ensuring the waterproof performance, the problems caused by too many embedded grooves are avoided. With the setting of the multiple layers of annular water-blocking tapes, even if one or several of the annular water-blocking tapes are damaged, the other intact water-blocking tapes can still maintain a certain sealing effect, ensuring that the overall waterproof performance of the manhole cover will not be completely invalidated due to local damage. When replacement or maintenance is required, only this one sealing ring needs to be operated, which greatly simplifies the maintenance process and reduces the maintenance cost.

[0008] In a preferred implementation, the outer wall of the manhole cover body is provided with two annular grooves to form a double-enclosed multi-sealed waterproof structure.

[0009] Without destroying the strength of the well body, a double-enclosed multi-sealed waterproof structure is formed, which greatly improves the waterproof performance. Even in extreme cases, such as the well cover being flooded, it can effectively prevent moisture from seeping into the well, ensuring the normal operation and safety of the facilities in the well.

[0010] In a preferred implementation, the sealing ring is a non-interface sealing ring made of silicone to improve the sealing effect.

[0011] The entire sealing ring is a continuous whole without any breaks or seams, which significantly improves the sealing effect. At the same time, silicone is a material with excellent elasticity and durability. The silicone sealing ring can fit tightly between the manhole cover and the well body to form an effective sealing layer. The silicone material also has good weather resistance and chemical stability, and can resist the erosion of various harsh environments and chemicals to maintain long-term sealing performance. The silicone material has good flexibility and resilience, which allows the sealing ring to be bent repeatedly without being easily damaged, extending the service life of the sealing ring and reducing maintenance costs.

[0012] In a preferred implementation, a sealing belt is provided on the sealing ring near the edge of the manhole cover, and the sealing belt is used for sealing the overlapping position between the manhole cover and the well body.

[0013] The sealing tape is set at the overlap position between the manhole cover and the well body. When the sealing tape is used in combination with the sealing ring water blocking tape, the sealing effect is more outstanding. The sealing ring water blocking tape mainly acts on the main sealing area between the manhole cover and the well body, while the sealing tape is used for the details of the overlap position. The two complement each other and jointly build a multi-level waterproof system, which greatly improves the waterproof performance of the manhole cover.

[0014] In a preferred implementation, the cross section of the annular water blocking belt gradually widens toward the sealing ring.

[0015] The gradually widening cross-section design helps to enhance the structural strength and stability of the barrier strip. The wider cross-section means that more material is used to support the annular barrier strip, so that it can withstand greater pressure and impact force, thereby extending the service life of the annular barrier strip.

[0016] In a preferred implementation, a mounting portion is provided on the back of the manhole cover to install a smart bin, and a collector is arranged in the smart bin.

[0017] In a preferred implementation, the smart bin is mounted on the mounting portion via spring anti-slip screws.

[0018] In a preferred implementation, a cross-shaped glass fiber reinforcement rib is provided inside the manhole cover to enhance the pressure-bearing capacity of the manhole cover without blocking the collector signal.

[0019] The glass fiber material itself has a weak ability to block signals. Compared with conductive materials such as metals, the glass fiber material has a lower ability to absorb and reflect electromagnetic waves, so it also has less interference with signals. This allows the cross-shaped glass fiber reinforcement to enhance the pressure-bearing capacity of the manhole cover without significantly affecting the transmission of the collector signal.

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the present invention, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be the first and second features directly contacting, or the first and second features indirectly contacting through an intermediate medium.

[0029] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0030] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0031] The utility model is described below in conjunction with the accompanying drawings.

[0032] The specific plans adopted are:

[0033] like Figure 1-4As shown, the utility model provides a glass fiber reinforced waterproof manhole cover, including a manhole cover body 1, the outer wall of the manhole cover body 1 is provided with an annular groove 10, a sealing ring 2 is embedded in the annular groove 10, the groove depth of the annular groove 10 is equal to the ring width of the sealing ring 2, and the outer periphery of the sealing ring 2 is provided with a multi-layer spaced annular water-blocking belt 20, the annular water-blocking belt 20 is extended along the outer side direction of the sealing ring 2, the annular water-blocking belt 20 can be bent, and the bent annular water-blocking belt 20 abuts against the outer peripheral wall of the sealing ring 2 and the inner wall of the well body 5 to form multiple seals.

[0034] In the glass fiber reinforced waterproof manhole cover of the present application, the sealing ring 2 can be stably embedded in the annular groove 10, reducing the risk of damage caused by friction or external force. The sealing relies on the annular water-blocking tape 20 to be bent and abut against the outer peripheral wall of the sealing ring 2 and the inner wall of the well body 5, thereby ensuring its long-term effective sealing performance. Although only one sealing ring 2 is used, by arranging multiple layers of spaced annular water-blocking tapes 20 on the periphery of the sealing ring 2 and enabling them to be bent and abut against the inner wall of the well body 5, a multiple sealing effect is achieved. While ensuring the waterproof performance, the problems caused by too much embedding in the groove are avoided. The arrangement of the multiple layers of annular water-blocking tapes 20 means that even if one or several of the annular water-blocking tapes 20 are damaged, the other intact water-blocking tapes can still maintain a certain sealing effect, ensuring that the overall waterproof performance of the manhole cover will not be completely invalidated due to local damage. When replacement or maintenance is required, only this one sealing ring 2 needs to be operated, which greatly simplifies the maintenance process and reduces the maintenance cost.

[0035] As a preferred embodiment of the present application, the outer wall of the manhole cover body 1 is provided with two annular grooves 10, forming a double-enclosed multi-sealed waterproof structure. Without destroying the strength of the well body 5, a double-enclosed multi-sealed waterproof structure is formed, which greatly improves the waterproof performance. Even in extreme cases, such as the manhole cover being flooded, it can effectively prevent moisture from seeping into the well, thereby ensuring the normal operation and safety of the facilities in the well.

[0036] As a preferred embodiment of the present application, the sealing ring 2 is a non-interface sealing ring 2 made of silicone to improve the sealing effect.

[0037] The silicone sealing ring 2 adopts a non-interface design. The entire sealing ring 2 is a continuous whole without any breaks or seams, which significantly improves the sealing effect. At the same time, silicone is a material with excellent elasticity and durability. The silicone sealing ring 2 can fit tightly between the manhole cover and the well body 5 to form an effective sealing layer. The silicone material also has good weather resistance and chemical stability, and can resist the erosion of various harsh environments and chemicals to maintain long-term sealing performance. The silicone material has good flexibility and resilience, so that the sealing ring 2 can be bent repeatedly without being easily damaged, thereby extending the service life of the sealing ring 2 and reducing maintenance costs.

[0038] As a preferred embodiment of the present application, a sealing belt 21 is provided near the edge of the manhole cover of the sealing ring 2 , and the sealing belt 21 is used for sealing the overlapping position between the manhole cover and the well body 5 .

[0039] The design of the sealing tape 21 is mainly aimed at the overlap position between the manhole cover and the well body 5. When the sealing tape 21 is combined with the sealing ring 2 water blocking tape, the sealing effect is more outstanding. The sealing ring 2 water blocking tape mainly acts on the main sealing area between the manhole cover and the well body 5, while the sealing tape 21 is aimed at the details of the overlap position. The two complement each other and jointly construct a multi-level waterproof system, which greatly improves the waterproof performance of the manhole cover.

[0040] As a preferred embodiment of the present application, the cross section of the annular water blocking belt gradually widens toward the sealing ring 2 .

[0041] The gradually widening cross-section design helps to enhance the structural strength and stability of the barrier strip. The wider cross-section means that more material is used to support the annular barrier strip, so that it can withstand greater pressure and impact force, thereby extending the service life of the annular barrier strip.

[0042] As a preferred embodiment of the present application, by providing a mounting portion 11 on the back of the manhole cover, the smart bin 3 can be conveniently installed on the manhole cover to form an integrated management system. The extra-large smart bin 3 can be compatible with a variety of collectors, which simplifies the installation steps and makes the connection between the manhole cover and the smart bin 3 more stable and reliable. The collector in the smart bin 3 can collect the status data of the manhole cover in real time, such as position, opening and closing status, pressure changes, etc., providing city managers with the possibility of real-time monitoring and management.

[0043] Specifically, the smart bin 3 is mounted on the mounting portion 11 by means of spring anti-slip screws. When the manhole cover is subjected to external vibrations, such as a vehicle passing by or wind, the spring elements in the spring anti-slip screws can absorb and buffer these vibrations, reducing their impact on the installation stability of the smart bin 3.

[0044] In order to enhance the compression resistance and durability of existing composite manhole covers, steel bars are added inside the manhole covers for reinforcement. With the continuous advancement of smart city construction, the demand for intelligent management of infrastructure such as manhole covers is increasing. The composite manhole covers equipped with collectors can be better integrated into the smart city management system, achieve interconnection with other urban infrastructure, and improve the level of intelligent urban management. However, the presence of steel bars as reinforcing materials also causes interference or shielding of electromagnetic signals, which will interfere with the normal operation of the collector. This interference may manifest as signal attenuation, distortion or complete blocking, thereby affecting the accuracy and stability of the collector data. Therefore, in this embodiment, a cross-shaped glass fiber reinforcement rib 4 is provided inside the manhole cover to enhance the pressure resistance of the manhole cover without blocking the collector signal.

[0045] The glass fiber material itself has a weak ability to block signals. Compared with conductive materials such as metals, the glass fiber material has a lower ability to absorb and reflect electromagnetic waves, so it also has less interference with signals. This allows the cross-shaped glass fiber reinforcement ribs 4 to enhance the pressure-bearing capacity of the manhole cover without significantly affecting the transmission of the collector signal.

[0046] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0047] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
