Description

Technical Field

[0001] The utility model relates to the technical field of fire protection heat collecting covers, and more specifically, the utility model relates to a side spray fire protection heat collecting cover. Background Art

[0002] The sprinkler heat collecting cover belongs to the accessories in the fire protection sprinkler system and is used in conjunction with the fire protection sprinkler head. When the distance between the sprinkler head and the roof slab is greater than 30 cm, a heat collecting cover needs to be installed at the sprinkler head. The traditional side spray heat collecting cover is composed of two vertically connected stainless steel plates, and a through hole with the same size as the sprinkler thread is opened on the vertical plate. When installing, the heat collecting cover needs to be installed first, and then the sprinkler head is installed immediately. If a heat collecting cover is installed at the existing sprinkler head of the sprinkler system, the sprinkler head needs to be disassembled first, and the fire protection sprinkler system needs to be interrupted, and the sprinkler head needs to be removed after draining the water. There is not only a risk of water leakage during the disassembly of the sprinkler head due to the remaining water in the pipeline not being drained completely, but also the sprinkler head may be damaged during the disassembly process. Side wall type sprinkler heads are commonly used in the return air ducts of clean workshops, and the wind speed at the top end of the return air duct is relatively high. If the traditional side wall type heat collecting cover is used, the heat collecting cover is likely to rotate due to long-term air flow impact, thus blocking the lower part of the sprinkler head, making the sprinkler head unable to directly spray to the fire source in case of emergency. According to this situation, a side spray fire protection heat collecting cover is proposed. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a side spray fire protection heat collecting cover.

[0004] To achieve the above object, the utility model provides the following technical solution: a side spray fire protection heat collecting cover, including a side spray heat collecting cover main body, with a U-shaped installation groove opened at the end of its side surface, an L-shaped installation frame is arranged on the outer end surface of the side spray heat collecting cover main body near the U-shaped installation groove, a locking rivet is arranged on the end surface at the connection of the side spray heat collecting cover main body and the L-shaped installation frame, a U-shaped installation block is arranged on the lower end surface of the L-shaped installation frame, and a concave locking groove is opened on one side of the outer end surface of the L-shaped installation frame;

[0005] An installation slot is opened on the inner side of the vertical side plate of the L-shaped installation frame, a locking threaded rod is arranged on one side of the upper end of the U-shaped installation block, a locking nut is arranged on the outer end surface of the locking threaded rod, a plug rod is arranged on the upper end of the U-shaped installation block on the side far from the locking threaded rod, and a limit clamping block is arranged on the outer side of the upper end of the plug rod.

[0006] In a preferred embodiment, the cross-section of the side spray heat collecting cover main body in the front view direction is L-shaped, the number of the locking rivets is multiple, and they are arranged in an array on both sides of the vertical central axis in the right view direction of the side spray heat collecting cover main body.

[0007] In a preferred embodiment, the inner end face of the U-shaped mounting block has the same specifications as the inner end face of the U-shaped mounting groove, and in the right view direction, the inner end faces of the U-shaped mounting block and the U-shaped mounting groove are adapted to the outer end face of the fire sprinkler pipe.

[0008] In a preferred embodiment, the number of the concave locking grooves and the mounting slots is two each, and they are arranged in a mirror image state on both sides of the horizontal central axis in the top view direction of the L-shaped mounting bracket. The inner end face of the concave locking groove is adapted to the outer end face of the locking screw rod.

[0009] In a preferred embodiment, the inner end face of the mounting slot is adapted to the outer end face of the limit clamping block. The number of the locking screw rods, the locking nuts and the inserting rods is two each, and they are arranged in a mirror image state on both sides of the horizontal central axis in the top view direction of the U-shaped mounting block.

[0010] In a preferred embodiment, the limit clamping block is adapted to the upper end of the mounting slot by clamping, and the outer end face of the locking screw rod is adapted to the inner end face of the locking nut by threaded clamping.

[0011] The technical effects and advantages of the present utility model:

[0012] When the present utility model is actually used, in the set state of the corresponding settings of the side spray heat collecting cover main body, the locking rivets and the L-shaped mounting bracket, the stability of the installation connection between the side spray heat collecting cover main body and the L-shaped mounting bracket can be effectively increased. At the same time, in the set state of the corresponding settings of the mounting slot, the concave locking groove, the locking screw rod, the locking nut, the inserting rod and the limit clamping block, the stability of the installation of the side spray heat collecting cover and the fire sprinkler pipe can be effectively increased. At the same time, the side spray heat collecting cover can be installed on the existing sprinkler system without disassembling the sprinkler head, and it is more stable and reliable when applied to the return air duct of a clean workshop compared with the traditional side spray heat collecting cover.
