Description

Technical Field

[0001] This utility model relates to the field of fire protection, specifically to a fire-fighting rapid-start detector. Background Technology

[0002] Currently, in high-vibration transport vehicles such as buses and mining trucks, temperature sensing pipes are connected to the valve heads of fire extinguishing agent cylinders. During use, the temperature sensing pipes require continuous pressurization to maintain pressure balance. When vehicles are being repaired, untrained workers may easily disassemble the temperature sensing pipes, potentially leading to accidental spraying of the extinguishing agent. Therefore, a new type of rapid-start fire extinguishing detector is needed to replace the traditional temperature sensing activation structure, improving ease of installation and safe operation. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a rapid-start detector for fire protection, which solves the technical problems of existing detectors being cumbersome to install, requiring on-site pressure testing, and prone to causing accidental spraying of chemicals.

[0004] The technical solution of this utility model is: a fire alarm rapid-start detector, comprising:

[0005] A gas storage device is provided, with an air inlet at the top and an air outlet at the bottom. A hollow base is also connected to the bottom of the gas storage device. Several flame detection windows are opened on the side wall of the hollow base. A temperature control release device is coaxially arranged at the bottom of the air outlet of the gas storage device and the top of the hollow base. A locking nut is connected to the bottom of the hollow base. A temperature-sensing glass column is installed between the temperature control release device and the locking nut. A pressure release outlet is provided on the side wall of the gas storage device.

[0006] Furthermore, the temperature control release device includes a hollow cylinder in the lower middle part, with a first ring, a second ring, and a third ring integrally formed on the surface of the cylinder. A first rubber groove is provided on the inner side of the top of the first ring, a second rubber groove is formed between the first ring and the second ring, and a third rubber groove is formed between the second ring and the third ring. A first sealing ring, a second sealing ring, and a third sealing ring are respectively installed in the first, second, and third rubber grooves.

[0007] Furthermore, the pressure release outlet is provided on the side wall of the gas storage device at the position between the second rubber groove and the third rubber groove.

[0008] Furthermore, the number of flame detection windows is six.

[0009] Furthermore, the locking nut is coated with thread-locking adhesive.

[0010] Furthermore, the top of the temperature-sensing glass column is pointed.

[0011] Furthermore, the locking nut is an internal hexagonal nut.

[0012] Furthermore, the gas storage device stores high-pressure inert gas or high-pressure carbon dioxide gas.

[0013] The beneficial technical effects of this utility model are as follows: This utility model uses several flame detection windows, a gas storage device, a temperature-sensing glass column, a temperature-controlled release device, and a pressure release outlet to achieve gas release at a certain pressure, realizing instantaneous pressure suppression in fire alarm environments. This replaces the continuous pressure suppression structure in traditional start-up detectors, avoiding accidental spraying of extinguishing agents due to accidental disassembly of the temperature-sensing pipe. In use, the quick-start detector can be directly installed in the temperature-sensing area. When a fire alarm occurs, the valve head is instantly, quickly, and smoothly activated to ensure the safe release of the extinguishing agent from the cylinder. This quick-start detector greatly meets customer and market needs, is easy to install and maintain, and has significant market value. Attached Figure Description

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] See Figure 1-5 This specific embodiment discloses a fire alarm rapid-start detector, comprising:

[0024] A gas storage device 1 has an air inlet 2 at the top and an air outlet 3 at the bottom. A hollow base 4 is also connected to the bottom of the gas storage device 1. Several flame detection windows 5 are opened on the side wall of the hollow base 4. A temperature control release device 6 is coaxially arranged at the bottom of the air outlet of the gas storage device 1 and the top of the hollow base 4. A locking nut 7 is connected to the bottom of the hollow base 4. A temperature sensing glass column 8 is installed between the temperature control release device 6 and the locking nut 7. A pressure release outlet 9 is provided on the side wall of the gas storage device 1.

[0025] In this specific embodiment, the flame detection window 5 is a flame intrusion port used to sense the real-time temperature in the fire environment. When the ambient temperature sensed by the temperature sensing glass column 8 reaches the set sensing temperature, the glass instantly shatters. As the bottom of the temperature control release device 6 loses its locking function, the high-pressure gas in the gas storage device 1 pushes the temperature control release device 6 downwards instantly.

[0026] More specifically, the temperature control and release device 6 includes a hollow cylinder 61 in the lower middle part. A first ring 62, a second ring 63, and a third ring 64 are integrally formed on the surface of the cylinder 61. The cylinder 61 and the first ring 62, the second ring 63, and the third ring are all made of stainless steel. A first rubber groove 65 is provided on the inner side of the top of the first ring 62. A second rubber groove 66 is formed between the first ring 62 and the second ring 63. A third rubber groove 67 is formed between the second ring 63 and the third ring 64. A first sealing ring, a second sealing ring, and a third sealing ring (not shown in the figure) are respectively installed in the first, second, and third rubber grooves.

[0027] More specifically, a pressure release outlet 9 is provided on the side wall of the gas storage device 1 at the position between the second rubber groove and the third rubber groove 67. This pressure release outlet 9 is used to release the gas inside the gas storage device 1. In this specific embodiment, before the temperature-sensing glass column 8 is shattered, the gas outlet, gas inlet, and the first, second, and third sealing rings of the gas storage device 1 are used to seal the gas inside the gas storage device in multiple ways, ensuring that there is no gas leakage inside the gas storage device. When the temperature control release device 6 is pushed downward by the gas, the first, second, and third sealing rings all move to below the pressure release outlet 9. At this time, because the first sealing ring is placed inside the first ring 62, the first sealing ring does not wear when the cylinder 61 slides downward. Therefore, it can be ensured that the high-pressure gas of the gas storage device 1 is discharged only along the pressure release outlet 9, avoiding the leakage of high-pressure gas to the hollow base 4 side, that is, ensuring the gas release pressure of the pressure release outlet 9. This release pressure can ensure the activation of the valve connected to the detector, reducing the cumbersome process of traditional on-site pressure testing.

[0028] More specifically, there are six flame detection windows 5. Multiple flame detection windows 5 allow for instantaneous sensing of ambient temperature from multiple directions. When a flame appears in any direction, the temperature-sensing glass column 8 can shatter instantly, quickly activating the detector and improving the instantaneousness of temperature detection.

[0029] More specifically, the threads of the locking nut 7 are coated with thread-locking adhesive for locking it to the bottom of the hollow base 4, thereby ensuring tight contact with the temperature-sensing glass column 8.

[0030] More specifically, the top of the temperature-sensing glass column 8 is pointed, which facilitates insertion into the hollow cylinder 61 to complete the positioning of the top of the temperature-sensing glass column 8.

[0031] More specifically, the gas storage device 1 is filled with high-pressure inert gas or high-pressure carbon dioxide gas, and the specific gas pressure is flexibly set according to the actual application scenario.

[0032] More specifically, the locking nut 7 is an internal hexagonal nut, which is easy to insert into the hollow base 4 and keep the bottom of the entire start detector flat, so as to improve the placement stability of the start detector.

[0033] The working principle of this utility model:

[0034] In this specific embodiment, a fire-fighting rapid-start detector is connected to a valve head. In order to immediately open the valve head in the event of a fire alarm, thereby releasing the extinguishing agent from the extinguishing agent cylinder, the rapid-start detector utilizes the shattering of a temperature-sensing glass column to cause the high-pressure gas in the gas storage device to push the temperature-controlled release device to move downward instantaneously, thereby causing the high-pressure gas to be discharged from the pressure release outlet. The instantaneously discharged gas causes the valve head to open stably, thereby safely discharging the extinguishing agent.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
