Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipes, in particular to an antifreeze pipe for fire-fighting. Background Art

[0002] In the northern region of my country, in order to ensure the normal use of fire-fighting pipes in low temperature environments in winter, antifreeze fire-fighting pipes are generally installed. Usually, the better effect is to use deep burial and electric heating to provide antifreeze protection. Among them, the antifreeze effect of pipes equipped with electric heating equipment is more prominent.

[0003] However, the existing antifreeze fire-fighting pipes have certain defects in actual use. This is usually reflected in the fact that although the existing pipes equipped with electric heating equipment have a more outstanding antifreeze effect, the installed electric heating equipment is generally exposed to the external environment, and its own thermal efficiency is low. It is also easy to be damaged by bumps. Therefore, those skilled in the art provide an antifreeze pipe for fire protection to solve the problems raised in the above background technology. Utility Model Content

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an antifreeze-type pipe for fire fighting, comprising a water pipe structure, a pipe clamp structure and an antifreeze kit, wherein the water pipe structures are sealed and assembled by the pipe clamp structure, and the outer sides of the water pipe structures are each provided with an antifreeze kit, the water pipe structure comprises an inner water pipe, the antifreeze kit comprises a covering shell, a polyurethane insulation layer, an electric heating tape and a placement groove, the outer side of the inner water pipe is sealed with a pair of covering shells, the interior of the covering shells is provided with a polyurethane insulation layer, a placement groove is provided at the middle position of the inner wall of the covering shell, and an electric heating tape is provided at the position of the placement groove of the covering shell, and the electric heating tape is fitted with the inner water pipe.

[0006] Furthermore, a second assembly flange is fixedly provided on both sides of the covering shell, and the pair of second assembly flanges cooperate with each other and are sealed and assembled by multiple hexagonal bolts. The second assembly flanges facilitate the sealing of the pair of covering shells on the outside of the water supply inner pipe using the hexagonal bolts.

[0007] Furthermore, the cover shell has second through-grooves on both sides. A pair of these second through-grooves extend through the cover shell and into the placement grooves. Both ends of the heating cable extend through the second through-grooves to the outside of the cover shell. The second through-grooves and their connection to the placement grooves facilitate the installation of multiple sections of heating cable within the cover shell.

[0008] Furthermore, a temperature sensor is fixedly mounted on one side of the inner wall of the covering shell, and both the temperature sensor and the electric heating tape are electrically connected to the control terminal. This electrical connection between the temperature sensor and the electric heating tape facilitates real-time detection of the current temperature of the inner water pipe via the temperature sensor, and feedback of the detected data to the control terminal. This facilitates the control terminal controlling the electric heating tape to initiate heating when a specified heating temperature is reached, and also to shut down the electric heating tape when the temperature reaches a rated value.

[0009] Furthermore, the pipe clamp structure includes a connecting clamp, a matching convex ring and a sealing sleeve. The water pipe structure also includes matching grooves and leak-proof grooves opened on the outer sides of both ends of the water inner pipe. A pair of connecting clamps are symmetrically sleeved on the outer sides of the connection of a pair of water inner pipes. A pair of connecting clamps are fixedly provided with matching convex rings at the positions corresponding to the matching grooves on the inner sides of the pair of connecting clamps. A pair of sealing sleeves are fixedly provided with the positions corresponding to the leak-proof grooves on the inner sides of the pair of connecting clamps.

[0010] Furthermore, a first mounting flange is fixedly provided at the mating portion of the pair of connecting clamps. The first mounting flanges cooperate with each other and are sealed together by a plurality of hexagonal bolts. The first mounting flange facilitates the sealing of the pair of connecting clamps between the two water supply inner pipes using the hexagonal bolts, thereby completing the sealed assembly between the water supply inner pipes.

[0011] Furthermore, a protrusion is fixedly mounted at the upper end of the connecting clamp, and a first through-groove is formed through the protrusion. The electric heating cable, which extends to the outside of the covering shell, passes through the first through-groove. The protrusion, the first through-groove, and the coordination of the electric heating cable and the first through-groove facilitate the pulling and installation of the electric heating cable and reduce the exposed area of ​​the electric heating cable.

[0012] Compared with the prior art, the present invention provides an antifreeze pipe for fire protection, which has the following beneficial effects:

[0013] Compared with the traditional add-on electric heating structure, the equipment of this design adopts an enclosed shell structure design. Through the corresponding electric heating tape traction installation structure design and the insulation structure design inside the enclosed shell, the electric heating structure of the equipment has greatly improved the heating and anti-freezing effect on the fire protection pipes. The enclosed shell design itself can also well protect the originally exposed electric heating structure. At the same time, it also has a good insulation effect, greatly improving the thermal utilization efficiency of the electric heating structure and having certain energy-saving and environmental protection performance.

[0028] The working principle and use process of this utility model: When the device is actually used:

[0029] When installing the equipment, first place the concave side of the pair of connecting clamps 23 toward the water supply inner tube 13 and fit them to the connection of the pair of water supply inner tubes 13, so that the matching convex ring 25, the matching groove 12, the sealing sleeve 26 and the leak-proof groove 11 are sealed and fit together. At this time, the hexagonal bolts are installed and tightened on the first assembly side 24 on the side of the connecting clamps 23 to complete the sealing assembly of the water supply inner tube 13;

[0030] The electric heating cable 34 is then pulled out, introduced along the second through-groove 37 on one side of the covering shell 31, laid along the placement groove 35, led out through the second through-groove 37 on the other side of the covering shell 31, and introduced and pulled out along the first through-groove 21 on the connecting clamp 23, completing the laying of the electric heating cable 34 in one side of the covering shell 31.

[0032] In actual application, the temperature sensor 36 in the covering shell 31 will detect the surface temperature of the water inner pipe 13 in real time and feed back the real-time data to the control terminal. When the temperature is lower than the set value, the control terminal will automatically control the electric heating tape 34 to work and heat the water inner pipe 13.
