Description

Technical Field

[0002] At present, in civil and commercial buildings, the fire protection system is one of the main means to ensure the safety of people's lives and property and maintain the integrity of buildings. Civil and commercial buildings have complex structures, diverse shapes, accommodate a large number of people, have many ways for fire to spread, and are difficult to evacuate. Once a fire occurs, it is easy to cause serious consequences and is difficult to implement fire fighting.

[0003] The existing fire sprinkler is a common fire sprinkler equipment, which is suitable for the automatic fire extinguishing system pipe network in factories, hospitals, schools, shopping malls, and restaurants. The existing fire sprinkler forms a stable seal by supporting the sealing plate with a glass tube. The glass tube is filled with an organic solution with a high thermal expansion coefficient. When a fire occurs, the temperature of the organic solution rises and expands until the glass tube breaks. The sealing plate is washed away by the water flow after losing support, and then water spraying begins to extinguish the fire. The fire sprinkler is an important component in the fire protection system. In order to ensure the fire extinguishing effect, it is necessary to detect the fire sprinkler and the spraying condition of the fire sprinkler after the fire sprinkler is applied to the fire pipeline to ensure that the fire sprinkler can be used normally in the event of a fire. However, there is currently no device that can test the fire sprinkler in the fire simulation scene and the fire sprinkler sprays in sequence on the same pipeline. Utility Model Content

[0024] Embodiment 1

[0025] Refer to Figure 1 and Figure 2 , a fire sprinkler spraying experiment device, including a frame 10, the frame 10 is a cubic frame, the rear side wall, left side wall, right side wall and upper side wall of the frame 10 are respectively provided with water baffle 11, the water baffle 11 can prevent water from splashing everywhere, and the lower bottom surface of the frame 10 is provided with a steering wheel 12. The frame 10 is provided with a water supply mechanism 20, a spraying mechanism 30 and a lifting mechanism 40 for driving the spraying pipeline 31 to move up and down, and the lifting mechanism 40 can adjust the distance between the closed fire sprinkler 33 and the fire source simulation mechanism 50 according to the experimental requirements.

[0026] Refer to Figure 1 and Figure 2 , the water supply mechanism 20 includes a water supply pipeline 21, and a flowmeter 22, a pressure gauge 23 and a solenoid valve 24 are sequentially connected to the water supply pipeline 21. The spraying mechanism 30 includes a spraying pipeline 31, the spraying pipeline 31 is connected to the water supply pipeline 21 through a three-diameter connector 34, and two types of fire sprinklers are provided on the spraying pipeline 31, and the two types of fire sprinklers are respectively an open fire sprinkler 32 and a closed fire sprinkler 33. The difference between the open fire sprinkler 32 and the closed fire sprinkler 33 lies in whether there is a release device. The open fire sprinkler 32 always remains open, and the closed fire sprinkler 33 is equipped with a sensing element. When a fire occurs, the sensing element breaks and starts to work and spray. The spraying pipeline 31 is composed of at least three water pipes and two 90° elbow connectors and is in a U shape. At this time, the spraying pipeline 31 is horizontally placed. An open fire sprinkler 32 is provided below the water pipe on the left side of the U-shaped opening, and a closed fire sprinkler 33 is provided on the right side of the U-shaped opening. At this time, the two types of fire sprinklers are at the same height.

[0027] The lifting mechanism 40 includes a lead screw 41, a hand crank 42, an L-shaped base 43, a sliding block 44 and a sliding rail 45. The sliding block 44 is arranged on the spraying pipeline 31, and the sliding block 44 is slidably arranged on the sliding rail 45. The sliding rail 45 is vertically arranged on the frame 10. The L-shaped base 43 is arranged on the spraying pipeline 31, and the L-shaped base 43 is threadedly connected to the lead screw 41. The lead screw 41 is mounted on the upper side wall of the frame 10, and the upper end face of the lead screw 41 is welded and connected with the hand crank 42, and the hand crank 42 can make the lifting labor-saving and convenient.

[0028] Referring to Figure 1 and Figure 2 , a fire source simulation mechanism 50 is provided below the closed fire sprinkler 32. The fire source simulation mechanism 50 includes a combustion tray 51 for carrying the fire source and a support frame 52. A lifting mechanism is provided on the support frame 52. The lifting mechanism is preferably a support lead screw 53. The upper end face of the support lead screw 53 is fixedly welded with the combustion tray 51, and the lower end face of the support lead screw 53 is threadedly connected to the support frame 52. In this embodiment, the fire source is preferably a colorless and odorless fire source such as n-heptane or kerosene during combustion.

[0029] Embodiment 2

[0030] Referring to Figure 3 , this embodiment is basically the same as Embodiment 1 in structure and will not be elaborated here. The difference is that the spraying pipeline 31 is at least composed of two water pipes and a 90° elbow connector and is in an inverted L shape. At this time, the spraying pipeline 31 is horizontally placed. An open fire sprinkler 32 is provided below the horizontal water pipe, and a closed fire sprinkler 33 is provided on the side of the vertical water pipe. The closed fire sprinkler 33 is horizontally installed. At this time, there is a height difference between the open fire sprinkler 32 and the closed fire sprinkler 33.

[0031] Referring to Figure 1 and Figure 2 , the specific operation process of Embodiment 1 of this device is as follows:

[0032] When the water source comes from the water supply mechanism 20 to the spraying pipeline 31 in the spraying mechanism 30, at this time, the spraying pipeline 31 is in a C shape and is horizontally placed. The open fire sprinkler 32 sprays normally. Move the combustion tray 51 below the closed fire sprinkler 33. According to the requirements of the experimental conditions, adjust the distance between the fire source and the open fire sprinkler 32 through the lifting mechanism 40 and / or the support lead screw 53. When the combustion tray 51 in the fire source simulation mechanism 50 starts to burn, the sensing element of the closed fire sprinkler 33 senses the change in the ambient temperature and breaks, and starts to work and spray to extinguish the fire. This embodiment simulates that when a fire occurs, at the same horizontal height of the same pipeline, one kind of fire sprinkler has started to work, and whether the subsequent fire sprinklers can be normally heated and triggered, and detects the stability of the fire sprinklers and the fire extinguishing performance of the sprinklers.

[0033] Referring to Figure 3The specific operation process of the second embodiment of the device is as follows:

[0034] When water comes from the water supply mechanism 20 to the spraying pipe 31 in the spraying mechanism 30, the spraying pipe 31 is in an inverted L shape at this time, and the spraying pipe 31 is placed horizontally. The open fire sprinkler 32 and the closed fire sprinkler 33 have a certain height difference. The open fire sprinkler 32 sprays normally, and the combustion disk 51 is moved below the closed fire sprinkler 33. According to the experimental conditions, the distance between the fire source and the open fire sprinkler 32 is adjusted by the lifting mechanism 40 and / or the supporting screw 53. When the combustion disk 51 in the fire source simulation mechanism 50 starts to burn, the closed fire sprinkler 33 sensing element ruptures and senses the change in ambient temperature and ruptures, and starts to work to spray and extinguish the fire. This embodiment simulates that when a fire occurs, in the same pipeline with a height difference, a fire sprinkler has already started to work, and whether the subsequent fire sprinklers can be normally triggered by heat, and the stability of the fire sprinklers and the sprinkler spraying and fire extinguishing performance are detected.

[0035] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
