Description

Technical Field

[0001] The present application relates to the field of fire protection equipment housing manufacturing, and in particular to a fire sensor housing. Background Art

[0002] Firefighting technology plays an important role in society. With the development of various industries, the demand for firefighting technology is also growing. Especially in some harsh working environments, such as oil wells, mines, mountain tunnels, etc., due to harsh conditions such as high dust, high humidity, large temperature fluctuations and strong vibrations, the damage rate of firefighting equipment, especially firefighting sensors, is extremely high. The firefighting tasks in these places are important and arduous, so there is an urgent need for a shell that can effectively protect firefighting sensors in extremely harsh environments.

[0003] Traditional fire sensors are mainly used in cities, factories and other places, but there is a lack of corresponding products and solutions for harsh environments such as mining operations and oil well mining that require strict on-site fire protection. This leads to frequent damage and failure of on-site fire sensors, which cannot meet actual fire protection needs.

[0004] In order to solve this problem, the design of the fire sensor housing needs to consider multiple protection functions to cope with various challenges in harsh environments. For example, the housing needs to have good sealing performance to prevent water vapor and foreign matter from entering; at the same time, the housing also needs to be able to resist strong vibrations to protect the internal fire sensor components from damage; in addition, the housing also needs to be able to cope with changes in high and low temperature differences to provide a stable working environment for the internal components. However, existing fire sensor housings often have shortcomings in these aspects and are difficult to meet the use requirements in extremely harsh environments. Utility Model Content

[0005] The purpose of this application is to provide a new type of multifunctional protective fire sensor housing to solve the problem that the existing fire sensors are easily damaged in harsh environments.

Since the shell can effectively protect the fire sensor from environmental factors, it ensures that the sensor accurately and timely detects fire hazards, helps to detect fires early, quickly initiate fire emergency response, reduce property losses, protect personnel safety, and improve the overall fire safety management level.

[0031] To sum up, the fire sensor housing of the present application not only solves the application difficulties of existing fire sensors in harsh environments through the comprehensive use of advanced material science and precision mechanical design, but also promotes fire protection technology to higher standards, and provides reliable and efficient fire safety monitoring solutions for special working environments such as mines, oil wells, and tunnels.

[0043] In this embodiment, the fire sensor housing includes a base 3 and a top cover 1 installed on the top of the base 3. The base 3 and the top cover 1 are arranged to form a storage space for installing the sensor. The top cover 1 includes a cover ring body 11, a cover support column 12, and a cover top wall 13. The cover ring body 11 and the cover top wall 13 are connected by the cover support column 12, and there is a gap between adjacent cover support columns 12, so that the cover ring body 11, the cover top wall 13 and the cover support column 12 are configured to form a hole. A filter membrane 2 is installed in the storage space, and the filter membrane 2 can at least cover the hole. The base 3 includes a seat plate body 31 and a seat ring body 32, and the seat ring body 32 can be fixedly connected to the cover ring body 11 by a connecting structure. Optionally, the side wall of the seat ring body 32 is provided with a thread, and the side wall of the cover ring body 11 is provided with a thread adapted to the seat ring body 32, and the seat ring body 32 is fixedly connected to the cover ring body 11 by a thread. A threading plug 4 for threading the signal line is also provided, which passes through the top cover 1, and the threading plug 4 extends to the accommodating space. The threading plug 4 includes a plug body 42, an inner convex body 41 and an outer convex body 43 are provided at both ends of the plug body 42, and a threading through hole 44 is provided inside the inner convex body 41, the plug body 42, and the outer convex body 43; a seat opening 33 is provided on the wall of the seat ring body 32, and the threading plug 4 is installed at the seat opening 33, and the inner convex body 41 is located on the inner side of the wall of the seat ring body 32, and the outer convex body 43 is located on the outer side of the wall of the seat ring body 32. Further, a plug seat sealant 7 is applied at the connection between the threading plug 4 and the base 3, a hole line sealant is applied in the threading through hole 44 of the threading plug 4, and a seat cover sealant 8 is applied at the connection between the top cover 1 and the base 3. A plurality of damping plates 6 are fixedly connected to the bottom end of the base 3, and the damping plates 6 are made of copper and aluminum. The surfaces of the base 3, the top cover 1 and the threading plug 4 are passivated. Example

[0044] The present embodiment is different from the embodiment 1 in that a phase change material 5 is disposed in the accommodating space, and the phase change material 5 is a solid-solid phase change neopentyl glycol material. Example

[0045] In this embodiment, the difference from the embodiment 1 is that the hole on the top cover 1 can be arranged on the side wall of the seat ring body 32 of the bottom cover. Similarly, the seat opening 33 arranged on the wall of the seat ring body 32 and the installed threading plug 4 can also be arranged on the wall of the cover ring body 11 of the top cover 1. Example

For example, the side wall of the seat ring body 32 is provided with a slot, and the side wall of the cover ring body 11 is provided with a plug that matches the seat ring body 32. The seat ring body 32 and the cover ring body 11 are fixedly connected through the slot and the plug. Similarly, the slot and the plug can be interchanged or staggered.

[0047] With respect to the embodiments of the present application, this embodiment provides a specific structural design and manufacturing process of a fire sensor housing, aiming to demonstrate how to transform the above technical solution into an actual product to ensure effective protection of the fire sensor in harsh environments.

[0048] Base 3 and top cover 1: 304 stainless steel is used due to its excellent corrosion resistance and strength. The seat ring 32 of the base 3 is designed to be cylindrical to install the top cover 1, and the seat plate 31 at the bottom is set to be a flat plate to fix the position of the damping plate 6. The top cover 1 is designed to include a cover ring 11, a plurality of cover support columns 12 arranged at intervals, and a cover top wall 13, which ensures structural strength and forms a cavity to facilitate internal and external gas exchange.

[0049] Filter membrane 2: ePTFE (polytetrafluoroethylene) material with high efficiency waterproof and breathable properties is selected and cut to cover the holes designed on the base 3 and the top cover 1 to prevent water vapor from entering while allowing air circulation.

[0050] The wire plug 4 is made of PVC material and may contain metal reinforcing ribs to increase rigidity. It is designed with an inner convex body 41, an outer convex body 43 and a wire through hole 44 to facilitate the sealing and insertion of the signal line.

[0051] Damping sheet 6: Customized copper-aluminum composite damping sheet 6 has high damping performance and lightweight characteristics, effectively suppressing vibration.

[0052] Sealant: High temperature resistant, aging resistant and highly elastic silicone rubber sealant is used for sealing the connection between the threading plug 4 and the base 3, the threading through hole 44, and the top cover 1 and the base 3.

[0053] Phase change material 5: solid-solid phase change neopentyl glycol material is used and packaged in the accommodation space formed by the base 3 and the top cover 1 to adjust the temperature.

[0054] In actual application, the fire sensor is placed in the accommodation space. The signal line is passed through the wire through hole 44 of the wire plug 4, and the signal line is passed through the wire plug 4 to connect with the external monitoring system. The hole wire sealant is used for sealing. After the installation is completed, the fire sensor housing is subjected to performance tests, including tests on sealing performance, seismic performance, temperature control performance, etc.
