Description

Technical Field

[0001] The utility model relates to the field of water suction pipes, in particular to a strongly connected spiral water suction pipe. Background Art

[0002] Fire trucks are essential tools for fire rescue operations. They require large amounts of water to ensure timely fire extinguishing. This water is primarily obtained through suction pipes connected to fire hydrants, rivers, and ponds. Suction pipes typically utilize ribs as a pressure-bearing structure, with the ribs and base layer physically entangled by the molecular chains of the molten polymer material. However, after a period of use or repeated bending, the ribs can easily separate from the base layer, leading to cracks in the pipe and leakage, which can affect its performance.

[0003] In order to enhance the bonding strength between the reinforcing ribs and the base layer, technicians usually increase the thickness of the base layer to completely wrap the reinforcing ribs. However, the increased thickness directly affects the weight of the suction pipe, which brings a greater burden when used and is not conducive to use in emergency situations. Utility Model Content

[0004] In order to solve the above problems and other problems, the utility model is realized through the following technical solutions: a strong connection type spiral water suction pipe, including: a base layer; reinforcing ribs, the spiral ring of the reinforcing ribs is arranged in the base layer; the reinforcing ribs include a main body and a bite groove, the cross section of the main body is laterally symmetrically provided with a bite groove, and the bite groove is embedded in the base layer.

[0005] In one embodiment, the engaging groove is a groove with a narrow opening and a wide interior.

[0006] In one embodiment, the volume ratio of the main body to the engaging groove is 7:3.

[0007] In one embodiment, the ratio of the longitudinal width of the opening of the engaging groove to the longitudinal width of the main body is 15% to 20%.

[0008] In one embodiment, the ratio of the maximum longitudinal width of the engagement groove to the longitudinal width of the main body is 30% to 35%.

[0009] In one embodiment, the ratio of the transverse width of the engaging groove to the transverse width of the main body is 15%.

[0010] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: the strong-connection spiral water suction pipe proposed by the present invention enables the base layer and the reinforcing ribs to be tightly connected, thereby extending the service life of the water suction pipe.

[0014] See also Figures 1 to 2 The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0015] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those skilled in the art, and are not intended to limit the conditions for implementation of the present invention. Therefore, they have no substantial technical significance. Any structural modification, change in proportional relationship, or adjustment in size, without affecting the efficacy and purpose of the present invention, should still fall within the scope of the technical content disclosed in the present invention. At the same time, terms such as "left", "right", "up", "down", and "one" quoted in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships, without substantially changing the technical content, should also be considered as the scope of implementation of the present invention.

[0016] In this utility model, for the sake of clear description, the following explanation is made: the observer faces the Figure 1 The above description is only for the purpose of clearly describing the present invention, and does not indicate or imply that the structures or components referred to must have a specific orientation or be constructed in a specific orientation. Therefore, it should not be understood as limiting the present invention.

[0017] like Figure 1 As shown, a strong connection type spiral water suction pipe 1 is used for fire trucks to draw water. The water suction pipe 1 includes a base layer 11 and a reinforcing rib 12. The reinforcing rib 12 is spirally arranged in the base layer 11.

[0018] Specifically, the base layer 11 covers the reinforcing rib 12 by 80%.

[0019] Please combine Figure 1 and Figure 2The reinforcing rib 12 comprises a main body 121 and an engagement groove 122. The main body 121 is transversely defined with symmetrical engagement grooves 122. The base layer 11 fits within the engagement grooves 122, increasing the contact area between the base layer 11 and the reinforcing rib 12. The engagement grooves 122 are narrow openings with wide interiors. While increasing the contact area between the base layer 11 and the reinforcing rib 12, they also create an engagement effect, ensuring that the suction pipe 1 remains tightly connected despite environmental aging, bending fatigue, and other conditions, thereby extending the service life of the suction pipe 1.

[0020] Specifically, the volume ratio of the main body 121 to the engaging groove 122 is 7:3.

[0021] For the sake of clarity, the cross-section of the reinforcing rib 12 is used as an example. Preferably, the ratio of the longitudinal width of the opening of the bite groove 122 to the longitudinal width of the main body 121 is 15% to 20%; the ratio of the maximum longitudinal width of the bite groove 122 to the longitudinal width of the main body 121 is 30% to 35%; the ratio of the transverse width of the bite groove 122 to the transverse width of the main body 121 is 15%, which saves material and increases the contact area while retaining the pressure-bearing capacity of the reinforcing rib 12.

[0022] In summary, the strongly connected spiral water suction pipe proposed by the utility model enables the base layer and the reinforcing ribs to be tightly connected, thereby extending the service life of the water suction pipe.

[0023] Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
