Description

Technical Field

[0001] This application relates to the field of boiler equipment, and more specifically, to a protection device for a boiler water guide pipe. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in fuel. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The water guide pipe connected to the boiler is mainly used for cold water transportation and hot water output. To avoid damage to the water guide pipe and reduce heat loss, a protection device is usually installed on the outer side of the water guide pipe. The patent document with the publication number CN220668796U in the prior art provides a protection device for a boiler water guide pipe. This device drives the rotation of the rotating shaft by rotating the movable block two to wind up the pull rope, so that the hooks move towards each other, facilitating the closing of the upper and lower ring blocks of the installation ring. When the movable block two is released, under the action of two groups of torsion springs, the hooks rotate back and are engaged in the card slots to close the upper and lower ring blocks of the installation ring, making the installation of the installation ring more convenient.

[0003] Regarding the above related technology, the inventor believes that the hooks are limited by torsion springs, and the movable block one is limited by a spring pull, both having a certain elastic clearance space. When the water guide pipe transports water, there is vibration, which easily causes loosening and noise at the connection of the installation ring. Therefore, we propose a protection device for a boiler water guide pipe. Utility Model Content

[0004] In order to improve the problems proposed in the above background technique, this application provides a protection device for a boiler water guide pipe, adopting the following technical solutions:

[0005] A protection device for a boiler water guide pipe includes a main water guide pipe body and a protective sleeve wrapped around the outside, and further includes two arc-shaped plates hinged to each other. The arc-shaped plates are arranged on the outside of the protective sleeve. One side of the arc-shaped plate is fixedly connected with a connecting block. The connecting block has a semi-truncated cone structure, and an external thread is fixed on the connecting block. A connecting sleeve is arranged between the two arc-shaped plates. The connecting sleeve is in threaded cooperation with the external thread, and a rotating wheel is fixedly connected to one side of the connecting sleeve.

[0006] By adopting the above technical solution, after the arc-shaped plates are sleeved on the outside of the protective sleeve, the two arc-shaped plates are closed to each other. The connecting sleeve is sleeved on the outside of the two connecting blocks, and the rotating wheel is rotated, so that the connecting sleeve is in threaded cooperation with the external thread to make the two connecting blocks approach each other, thereby driving the two arc-shaped plates to approach each other to stably connect the protective sleeve to the main water guide pipe body.

[0007] Optionally, an anti-slip pad is fixedly connected to the inner side of the arc-shaped plate.

[0008] By adopting the above technical solution, the anti-slip pad can further increase the stability when the arc-shaped plate is connected to the protective sleeve.

[0009] Optionally, a positioning block is fixedly connected to one of the connecting blocks, and a positioning groove adapted to the positioning block is formed on the other connecting block.

[0010] By adopting the above technical solution, when the positioning block is inserted into the positioning groove, the two connecting blocks are connected, so as to facilitate the threaded connection between the connecting sleeve and the two connecting blocks.

[0011] Optionally, a limiting cavity having a frustum-shaped structure is formed on the connecting sleeve, and an internal thread is formed in the limiting cavity, and the internal thread is in threaded engagement with the external thread.

[0012] By adopting the above technical solution, the shape of the limiting cavity is the same as the shape after the two connecting blocks are combined, and the internal thread and the external thread are matched so that the connecting sleeve can gradually move the two connecting blocks closer to each other, so that the two arc-shaped plates cooperate to tightly clamp the protective sleeve.

[0013] Optionally, a limiting plate is fixedly connected to the connecting sleeve, a U-shaped plate is slidably connected to one of the arc-shaped plates, the U-shaped plate is in plug-in fit with the limiting plate, a blocking block is fixedly connected to the other arc-shaped plate, and the blocking block is in abutting fit with the U-shaped plate.

[0014] By adopting the above technical solution, after the connecting sleeve is connected to the connecting block, the U-shaped plate is slid to abut against the blocking block, so that the U-shaped plate can abut against the limiting plate, thereby limiting the rotation of the connecting sleeve and further improving the stability.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. After the arc-shaped plate is sleeved outside the protective sleeve, the two connecting blocks approach each other, and the connecting sleeve is threadedly connected to the two connecting blocks, so that the two connecting blocks gradually approach each other to tightly clamp the protective sleeve by the arc-shaped plate, with simple operation and stable connection.

[0017] 2. When the U-shaped plate is slid to be inserted into the limiting plate, the U-shaped plate can limit the rotation of the connecting sleeve, thereby further improving the connection stability of the arc-shaped plate to the protective sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
