Description

Technical Field

[0001] The utility model relates to the field of pipeline design, and more specifically to a mounting base for mounting a sensor and a sensor component comprising the mounting base. Background Art

[0002] At present, the air conditioning components of the aircraft environmental control system adjust the high-temperature and high-pressure gas from the air source to the gas with suitable temperature and pressure, and then transport it to the mixing chamber, where it is mixed with the recirculated air and then transported to the cabin. The air conditioning component outlet temperature sensor is installed on the duct downstream of the air conditioning component to measure the temperature at the outlet of the air conditioning component. Then, the controller monitors the over-temperature through the temperature measured by the outlet temperature sensor to protect the downstream low-pressure pipeline.

[0003] In addition, some models are also equipped with anti-icing control when the outlet pressure sensor of the air conditioning unit fails. Some models directly use the outlet temperature demand value of the air conditioning unit as the adjustment target of the air conditioning unit, that is, by adjusting the cold side flow of the air conditioning unit or the hot air bypass valve to adjust the outlet temperature of the air conditioning unit, and then achieve the purpose of adjusting the cabin temperature.

[0004] Therefore, the outlet temperature sensor of the air conditioning assembly is very important for the normal operation of the aircraft. Whether its function is normal will affect the normal function of the aircraft air conditioning system. It is also an important guarantee that the downstream low-pressure pipeline or air distribution system or equipment will not be damaged.

[0005] In hot days, standard days, and icy days, there are situations where the air is relatively humid, the demand for cooling capacity is large, or the outlet temperature of the air conditioning component is low. At this time, the humid air expands and cools down greatly at the turbine of the air conditioning component, and the temperature is far below 0 degrees. Therefore, more and more ice will gradually accumulate on the turbine blades and condenser fins. When the ice accumulates to a certain amount, the flow resistance in the flow channel will increase. At this time, the air conditioning component will start the de-icing mode and use bypass hot gas to melt the ice. When the de-icing mode is started, larger ice will fall off from the turbine blades and the fins at the condenser outlet, and be transported to the outlet pipeline of the air conditioning component with the airflow. At this time, these larger ice crystals may hit the probe of the outlet temperature sensor of the air conditioning component, causing the probe to bend and deform, causing damage to its structure, and thus affecting its normal function.

[0006] Typical sensor bases in the prior art do not include protection means for protecting the sensor from ice crystal impacts, so the sensor, in particular the probe of the sensor, is at risk of being damaged by ice crystal impacts generated upstream.

[0007] Therefore, there is an urgent need to propose a mounting base for mounting a sensor, which can protect the sensor from being damaged by impact of foreign objects and does not affect the detection accuracy requirement. Utility Model Content

[0055] The present invention is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present invention are described. Obviously, all features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any way.

The technical solution of the present invention is described in many aspects in combination with the figures and embodiments below.

[0056] In this document, serial numbers "first", "second", etc. do not represent order (for example, do not imply a precedence relationship unless explicitly stated) or priority or importance. The above serial numbers are only used to indicate that they are different and independent devices, elements or steps.

[0057] In this document, the terms “inside”, “outside”, “inward”, “outward”, “upper side”, “lower side”, etc. are only used to describe the relative positions of various elements.

[0058] Figure 1 FIG. 1 shows a mounting base 1100 for a sensor 130 according to the prior art. The sensor 130 includes a sensor body 131 and an extension section 132 extending from the sensor body. For example, the extension section 132 is a probe extending from the sensor body 131, but may also be other structural components extending from the sensor body 131. Typical sensor bases in the prior art are as follows: Figure 1As shown, the sensor mounting base 1100 does not include a protection device for protecting the sensor 130 from ice crystals, so the sensor 130, especially the extended section 132 (eg, probe) of the sensor 130, is at risk of being damaged by ice crystals generated upstream. For example, the sensor 130 is a temperature sensor.

[0059] The mounting base 100, 200, 300 according to various embodiments of the present invention comprises a main body section 110, 210, 310 and a protection section 120, 220, 320 extending from the main body section 110, 210, 310. The protection section 120, 220, 320 at least partially covers the extension section 132 of the sensor 130 in the circumferential direction, and must completely cover the extension section 132 of the sensor 130 in the length direction. Here, the term "length direction" refers to the extension direction of the extension section 132, and the term "circumferential direction" refers to the direction surrounding the outer surface of the extension section 132 and orthogonal to the length direction thereof. The various embodiments of the present invention will be described below in conjunction with Figures 2 to 5.

[0060] Figure 2a and 2b The front view and cross-sectional view of the mounting base 100 according to the first embodiment of the utility model are shown. As shown in the figure, the mounting base 100 includes a main body section 110. The main body section 110 has an internal threaded portion 111 and a groove 112 for mounting a sensor 130. The sensor body 131 of the sensor 130 includes an external threaded portion corresponding to the internal threaded portion 111. The mounting base 100 also includes a protective section 120 extending from the main body section 110. The protective section 120 is configured to protect the extension section 132 of the sensor 130 from being damaged by foreign objects. There are a number of holes 121 on the protective section 120 to facilitate the extension section 132 such as a probe of the sensor 130, such as a temperature sensor, to contact the fluid flowing in the conduit, while reducing the disturbance of the fluid in the conduit.

[0061] The length of the protection section 120 extending from the main section 110 is greater than or equal to the length of the extension section 132 extending from the sensor body 131, so that after assembly, the lower end of the extension section 132 is higher than the lower end of the protection section 120. In other words, the extension section 132 does not extend from the protection section 120.

[0062] In such Figure 2a and 2bIn the first embodiment of the utility model shown, the protection section 120 of the mounting base 100 is a sleeve, preferably a cylindrical sleeve, and there are a plurality of holes 121 on the sleeve, that is, the protection section 120 is preferably a porous hollow cylinder. During assembly, the extension section 132 of the sensor 130 is placed in the sleeve-shaped protection section 120, so that the protection section 120 completely covers, that is, completely surrounds the side of the extension section 132, to prevent the extension section 132 from being damaged by foreign objects. The protection section 120 can be optionally made of a metal material with appropriate strength and corrosion resistance and no toxicity to ensure that the fluid flowing through the protection section 120 can meet the conditions for being transported to the cabin.

[0063] Figure 3 The figure shows a schematic diagram of fixing between the mounting base 100 and the conduit 140 according to the first embodiment of the utility model. Preferably, the mounting base 100 and the conduit 140 are fixed by welding, which can reduce the difficulty of processing and assembly and is beneficial to the air tightness of the conduit. The welding part is located at the lower edge of the main body section 110, so that the main body section 110 of the mounting base 100 is located on the outside of the conduit 140, and the protective section 120 of the mounting base 100 is located on the inside of the conduit 140. A heat insulation layer 150 is provided on the outside of the conduit 140, and the heat insulation layer 150 is made of a heat insulation material. Preferably, the height of the main body section 110 of the mounting base 100 located on the outside of the conduit 140 is higher than the thickness of the heat insulation layer 150, as shown in the figure. Alternatively, the height of the main body section 110 of the mounting base 100 outside the conduit 140 is not higher than the thickness of the insulation layer 150, but a hole is opened in the insulation layer 150 to expose the main body section 110 of the mounting base 100 so that the main body section 110 is accessible.

[0064] Figure 4a and 4b The figure shows a front view and a side view of a mounting base 200 according to a second embodiment of the present invention. In the second embodiment of the present invention, the protection section 220 of the mounting base 200 is a half sleeve, and a plurality of holes are formed on the half sleeve. During assembly, the extension section 132 of the sensor 130 is placed in the protection section 220 in the form of a half sleeve, so that the protection section 220 partially covers one side of the extension section 132, in other words, the protection section 220 surrounds the extension section 132 on one side of the extension section 132.

[0065] Specifically, in the flow direction, the half-sleeve protection section 220 is located at the upstream side of the extension section 132, that is, at one side in the incoming flow direction. From the incoming flow direction, the half-sleeve protection section 220 extending from the main section 210 completely covers the extension section 132. In this way, the protection section 220 can protect the extension section 132 from being damaged by foreign objects in the incoming flow direction. Foreign objects from the incoming flow direction will be blocked by the protection section 220 and will not hit the extension section 132. In addition, the half-sleeve protection section 220 can save materials and reduce weight.

[0066] Figure 5a and 5b The figure shows a front view and a side view of a mounting base 300 according to a third embodiment of the present invention. In the second embodiment of the present invention, the protection section 320 of the mounting base 300 is a fan-shaped section, and a plurality of holes are provided in the fan-shaped section. During assembly, the extension section 132 of the sensor 130 is placed on one side of the protection section 320 in the form of a fan-shaped section, so that the protection section 320 partially covers one side of the extension section 132, in other words, the protection section 320 covers the extension section 132 on one side of the extension section 132. The extension length of the protection section 320 is greater than or equal to the length of the extension section 132 extending from the sensor body 131, so that after assembly, the lower end of the extension section 132 is higher than the lower end of the protection section 320, in other words, the extension section 132 does not extend from the protection section 320. The protection section 320 has an appropriate width to strike a balance between protection performance and overall weight.

[0067] Specifically, in the flow direction, the protection section 320 in the form of a fan-shaped section is located on the upstream side of the extension section 132, that is, on one side in the incoming flow direction. When viewed from the incoming flow direction, the protection section 320 in the form of a fan-shaped section extending from the main section 310 completely covers the extension section 132. In this way, the protection section 320 can protect the extension section 132 from being damaged by foreign objects in the incoming flow direction, and the protection section 320 in the form of a fan-shaped section can also save materials and reduce weight.

[0068] The utility model also proposes a sensor assembly, which includes a sensor 130, and the sensor 130 includes a sensor body 131 and an extension section 132 (such as a probe), wherein the sensor assembly further includes a mounting base 100, 200, 300 as described in the above embodiments, for mounting the sensor 130. The sensor 130 is mounted on the mounting base 100, 200, 300, and the protection section 120, 220, 320 of the mounting base 100, 200, 300 can protect the extension section 132 of the sensor 130 from being damaged by foreign objects without affecting the detection accuracy.

[0069] In this document, the terms "include", "comprises" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, structure or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, structure or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, structure or device that includes the elements.
