Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire protection facility detection, in particular to a building fire protection detection device. Background Art
[0002] The fire sprinkler head is an important part of the fire sprinkler system, which is usually composed of two parts: the sprinkler head and the heat sensitive element. Its working principle is: at room temperature, the shell of the heat sensitive element can withstand a certain supporting force to maintain the sealing performance of the sprinkler head; when a fire occurs, the ambient temperature rises, and the organic solution inside the heat sensitive element expands due to heat, which breaks the shell of the heat sensitive element. After the sprinkler head loses the seal of the heat sensitive element, it sprays water to extinguish the fire.
[0003] However, in cold application environments, fire sprinkler heads may malfunction due to long-term exposure to low temperatures. Although no obvious damage is found on the surface, they are actually unusable, resulting in the inability to effectively contain the fire when it occurs. Therefore, it is essential to detect the failure rate of fire sprinkler heads in cold environments.
[0004] However, most of the existing fire sprinkler head testing equipment performs sampling testing on newly produced fire sprinkler heads under normal temperature conditions. Fire sprinkler heads are less affected by the environment, and there will be a significant deviation between the failure rate obtained from the sampling test and the actual failure rate.
[0005] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0031] Among them, a plurality of external pipes 111 are installed on the inner top of the detection zone 11, and one end of each of the external pipes 111 is located inside the detection zone 11, and the other end extends out of the shell 1; a heating wire 2 is arranged on one side wall of the detection zone 11; thereby, when detection is required, the staff connects the fire sprinkler head 6 under cold conditions with the external pipe 111, and places the temperature sensor in the detection zone 11; then the heating wire 2 is energized, and the heating wire 2 generates heat after being energized, so that the temperature inside the detection zone 11 gradually increases, simulating the scene of a fire under cold conditions; at this time, the staff observes the detection zone 11 and the temperature inside the detection zone 11 increases. The water spraying condition after the heat sensitive element in the zone 11 bursts, and the probability of water spraying after the heat sensitive element expands and bursts is recorded, so as to detect the failure rate of the fire sprinkler head 6 applied to cold conditions; at the same time, the staff records the corresponding temperature when the heat sensitive element expands and bursts, so as to obtain the temperature at which the heat sensitive element bursts under cold conditions; then the temperature at which the heat sensitive element bursts under cold conditions is compared and analyzed with the temperature at which the heat sensitive element expands and bursts under normal temperature (the heat sensitive element will expand and burst at about 68 degrees under normal temperature), so as to obtain the temperature difference law of the expansion and bursting of the heat sensitive element under the two conditions, which is conducive to further research and development;
[0032] Furthermore, a plurality of external pipes 121 are installed on the inner top of the second detection zone 12, and a water storage tank 3 is installed on the outside of the shell 1. One end of each of the external pipes 121 is located inside the second detection zone 12, and the other end extends out of the shell 1 and is connected to the water storage tank 3; thereby, the staff connects the fire sprinkler head 6 in cold conditions to the external pipe 121, and then allows the water in the water storage tank 3 to flow naturally to the fire sprinkler head 6; at this time, the staff observes the water leakage of the fire sprinkler head 6 and keeps a record, and after multiple tests, the probability of water leakage of the fire sprinkler head 6 in cold conditions can be detected;
[0033] Furthermore, a plurality of external tubes 3 131 are installed at the inner top of the detection zone 3 13, and one end of each of the external tubes 3 131 is located inside the detection zone 2 12, and the other end extends out of the shell 1; thereby, the staff connects the shower head 7 with the heat-sensitive element removed under cold conditions to the external tube 3 131, and then observes the water spraying condition of the shower head under the natural condition without the heat-sensitive element blocked; after multiple tests, the probability of the cold condition causing failure of the shower head itself can be obtained.
[0034] Preferably, all external tubes 111 are arranged in a straight line, and the heating wire 2 is parallel to the direction in which the external tubes 111 are arranged in a straight line; such an arrangement makes the distance between the heating wire 2 and the fire sprinkler head 6 the same, which is more accurate when detecting the failure rate of the fire sprinkler head 6 used in cold conditions.

[0037] See also Figure 1 , Figure 2 Preferably, the connection between the circulating water pipe 41 and the circulating water tank 4 is located in the middle of the side wall of the circulating water tank 4; in this way, since the large particles of impurities in the circulating water tank 4 sink to the bottom of the tank after the water in the circulating water tank 4 settles, the connection between the circulating water pipe 41 and the circulating water tank 4 is located in the middle of the side wall of the circulating water tank 4. This can prevent the impurities from being drawn away during circulation, thereby preventing the impurities from clogging the fire sprinkler head 6 and causing deviations in the detection results.
[0038] See also Figure 2 Preferably, a bottom bin 16 is opened at the bottom of the shell 1, and an industrial refrigeration equipment 5 is placed in the bottom bin 16; considering that the fire sprinkler head 6 cannot be used in cold conditions in some seasons, the staff can put the fire sprinkler head 6 under normal temperature conditions into the industrial refrigeration equipment 5 for a long time of low-temperature refrigeration, and then take it out for testing, so as to facilitate simulation testing in various seasons.

[0044] 2. The staff connects the fire sprinkler head 6 in cold conditions to the external pipe 2 121, and then allows the water in the water storage tank 3 to flow naturally to the fire sprinkler head 6; the staff observes the water leakage of the fire sprinkler head 6 and keeps a record. After multiple tests, the probability of water leakage of the fire sprinkler head 6 in cold conditions is detected.
[0045] 3. The staff connects the sprinkler head 7 with the heat sensitive component removed under cold conditions to the external pipe 3 131, and then observes the water spraying of the sprinkler head under natural conditions without the heat sensitive component blocked; after multiple tests, the probability of the sprinkler head itself being caused by cold conditions can be obtained.

By using the first detection zone to detect the fire sprinkler head, the failure rate of the fire sprinkler head used in cold conditions can be obtained; at the same time, the staff can compare and analyze the temperature of the heat sensitive element bursting under cold conditions with the temperature of the heat sensitive element expansion and bursting under normal temperature, and can also obtain the temperature difference law of the heat sensitive element expansion and bursting under the two conditions, which is conducive to further research and development; by using the second detection zone to detect the fire sprinkler head, the probability of water leakage in the fire sprinkler head under cold conditions can be obtained; by using the third detection zone to detect the sprinkler head with the heat sensitive element removed, the cold The probability of the sprinkler head itself being caused by the conditions is reduced; by arranging all the external pipes in a straight line and making the heating wire parallel to the direction of the external pipes in a straight line; so that the distance between the heating wire and the fire sprinkler head is the same, it is more accurate in detecting the failure rate of the fire sprinkler head used in cold conditions; by setting a circulating water tank, the water used in the detection can flow into the circulating water tank through the drainage hole for storage, avoiding unnecessary waste of water resources; by arranging the connection between the circulating water pipe and the circulating water tank in the middle of the side wall of the circulating water tank, it can prevent impurities from being drawn away during circulation, and avoid impurities clogging the fire sprinkler head and causing deviations in the detection results.
