Description

TECHNICAL FIELD

[0001] The application discloses a sprinkler, in particular to a low water pressure self-adaptive sprinkler. BACKGROUND

[0002] There are various types of sprinklers, and they are widely used. A sprinkler called a fire sprinkler is installed on a fire pipe. The fire sprinkler is a core water spraying device of a fire sprinkler system, and achieves fire initial control through automatic water spraying. The device is composed of a water sprayer, a heat-sensitive glass ball, a water pipe plug and the like. The heat-sensitive glass ball is filled with kerosene or ether solution. Different colors correspond to specific action temperatures: red corresponds to 68 DEG C, yellow corresponds to 79 DEG C, green corresponds to 93 DEG C, and blue corresponds to 141 DEG C. Red is the most commonly used color in life. When the ambient temperature exceeds the set threshold or is extruded or collided by external force, the glass ball breaks to release the pressure water flow to extinguish the fire.

[0003] However, when the glass ball breaks due to heat explosion or accidental breakage in normal operation, the fragments have a potential risk of explosion injury. Especially in the case of accidental breakage, the fragments will be sprayed out with the water flow when people are around the sprinkler. Due to the blockage of the sprinkler splash tray and the small size of the fragments, it is not easy to notice, and it can cause slight scratches on the skin or eyes of people close by. Even if there is no one close by when the glass ball breaks, the broken glass debris will be left on the ground. If the use is completed or the maintenance is completed, the glass debris will be carried to the surrounding area by the water flow sprayed on the ground and wall. As a result, the safety hazard is easily ignored or neglected during cleaning, especially when the subsequent cleaning is not careful, and when people are barefoot in the room, it is easy to cause injury.

The second elastic member 7 is provided with a clamping groove 23 for accommodating the deformed first elastic member 5, and the deformed first elastic member 5 is embedded in the clamping groove, thereby avoiding the deformation of the first elastic member 5 under the impact of water flow. The second elastic member 7 is supported by the second pushing member 17, and the first elastic member 5 is supported by the second elastic member 7, thereby ensuring that the limiting position will not be reset and will not be missed.

[0030] The support assembly comprises a support rod 19 rotatably connected with the second elastic member 7, the other end of the support rod 19 extends to the support member 4, the support member 4 is slidably connected with a sliding block 20 connected with the support rod 19, and the sliding block 20 is rotatably connected with the support rod 19.

The connecting rod 13 is provided with an opening 37 for accommodating the movement of the elastic member 7 without blocking the elastic member 7, the elastic member 7 is larger than the elastic member 5, and the edge of the elastic member 7 is embedded in the opening 37 of the connecting rod 13 and moves upwards along the opening 37 when deformed, thereby avoiding being blocked.

[0032] The support 4 is rotationally connected with a limiting member two 30, one end of the limiting member two 30 is in abutment with the bottom of the fixed member 6, and the other end is provided with a clamping member two 31, the support 4 is rotationally connected with a winding member 32, the winding member 32 is wound with a pull rope 33, the winding member 32 is provided with a clamping groove two 34 for accommodating the clamping member two 31, the pull rope 33 extends upward along the connecting rod 13 to the nozzle body, and the pull rope 33 is connected with the pushing member one 16, the nozzle body 1 is provided with a guide wheel 35 for guiding the movement and changing the direction of the pull rope 33, the limiting member two 30 and the support 4 are provided with a torsional spring two 36, one end of the winding member 32 penetrates out of the support 4, the winding member 32 and the support 4 are provided with a torsional spring three 38 for pushing the winding member 32 to reset, the fixed member 6 will cancel the blocking of the limiting member two 30 at the moment of upward movement, the torsional spring two 36 at the rotating point of the limiting member two 30 will immediately push the limiting member two 30 to rotate, thereby the end of the limiting member two 30 in abutment with the fixed member 6 moves upward, and the other end with the clamping member two 31 moves downward, driving the clamping member two 31 away from the clamping groove two 34 of the winding member 32, canceling the cooperation with the clamping groove two 34 and the restriction on the winding member 32, at this time the torsional spring three 38 in the winding member 32 instantly pushes the winding member 32 to reset, and releases the winding of the pull rope 33, the other end of the pull rope 33 is connected with the pushing member one 16, and is released to cancel the pulling of the pushing member one 16, the spring three 18 at the rear end of the pushing member one 16 is released instantly to make the pushing member one 16 move outward quickly, and the edge of the pushing elastic member one 5 makes the elastic member one 5 deform, by setting the elastic force of the spring three 18, the pushing reset time is faster than the downward movement of the water pipe plug 2, thereby ensuring that the elastic member one 5 deforms first, and the elastic member one 5 originally has a little curved state, even without pushing, it can also play a shielding effect, and the connecting rod 13 at the elastic member one 5 is provided with two arc-shaped ribs to block the elastic member one 5, ensuring that the elastic member can be blocked, and deforming to separate from the ribs under the force of the pushing member one 16 before moving, so as to more ensure that the elastic member one 5 can deform to shield the glass fragments, and the pull rope 33 moves along the guide wheel 35 to move and change direction, finally the elastic force of the torsional spring two 36, the torsional spring three 38 and the spring three 18 is large, which can be quickly reset at the moment of release, thereby ensuring the movement of the pushing member one 16.

[0033] Finally, when this device is installed and used, if the thermal glass ball 3 breaks, spring 18 instantly pushes the fixing member 6 upward, and the bottom causes the limiting member 20 to release and move upward, driving the locking member 21 downward. This causes the winding member 32 to release, and spring 38 to release as well, causing the pushing member 16 to move downward, pushing the elastic member 5 to deform. The fixing member 6 moves upward, simultaneously driving the pushing member 27 to move upward, also pushing the elastic member 27 to deform and bend upward. Then the water pipe plug 2 moves downward, driving the elastic member 5 downward, while the abutting block 10 moves upward simultaneously with the fixing member 6, and removes the obstruction of the limiting member 26, causing the limiting member 26 to drive the locking member 27 to disengage from the limiting groove 28. Then, after the elastic member 27 has deformed, it can move upward and fit with the elastic member 5, so that the elastic member 15 and the elastic member 27 form a cover to cover the broken thermal glass ball 3, reducing the amount of glass fragments. The spray nozzles effectively prevent splashing and scattering, thus avoiding scratches to people and reducing safety hazards. They also minimize the amount of flying glass shards and prevent scattering, avoiding potential hazards to pedestrians and subsequent cleaning if the nozzles are not properly cleaned. After covering the nozzles, maintenance personnel can easily replace them for easy cleaning, reducing harm and potential risks. The disassembled nozzle body can be reused by re-attaching a new thermal glass bulb 3. This is achieved by manually rewinding the retractor 32, pushing the water pipe plug 2 upwards to insert it, straightening the elastic element 5, and then pulling the rope connecting the support 4 to the limiting block 11 outwards. Finally, the limiting block 11 is reset, a new glass bulb is placed on the fixing element 6 and secured, and the fixing element 6 is pushed downwards to reset and reuse the nozzle. This saves costs and reduces unnecessary waste. Compared to existing technologies, this application is safer, more reliable, reduces safety hazards, and provides greater assurance.
