Description

Technical Field

[0001] The utility model relates to the technical field of building indoor environmental quality measurement, in particular to a building indoor temperature and humidity gradient measurement device. Background Art

[0002] When measuring the indoor environmental quality of a building, air temperature and humidity are the two most basic quantities of the four elements that need to be measured. When it is necessary to measure the indoor air temperature and humidity of a building, the equipment used is called a temperature block (which can measure indoor temperature and humidity). In many cases, it is necessary to measure temperature and humidity at a specific height inside the building, such as measuring temperature and humidity at 1m, 1.75m, 2m, 2.2m, and 2.8m indoors. Since the indoor space of a newly built building is relatively open, it is more troublesome to place the temperature and humidity blocks. Usually, bricks and other objects are found on site for placement, or iron wire is used to fix them on the wall. When stacking bricks, the height is difficult to control, and it is difficult to unify the test points in the longitudinal direction on a straight line (five instruments may be used for measurement, but the five measuring points are not on a straight line in the vertical direction). This will lead to a large deviation between the accuracy of the test and the ideal result of the experiment. However, the method of fixing the iron wire on the wall will also affect the accuracy of the measurement due to its placement close to the wall. Summary of the invention

[0026] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0027] Please see Figure 1 , Figure 2The utility model provides a device for measuring indoor temperature and humidity gradient of a building, including a support mechanism and a measuring instrument installed on the support mechanism; the support mechanism includes a support plate 01, a lower bracket 02, a support rod 03, and a containing assembly 04 evenly distributed on the support rod 03; the lower bracket 02 is hinged to the bottom of the support plate 01, the support rod 03 is longitudinally arranged on the top of the support plate 01, and the containing assembly 04 includes a hanging member 41 and a breathable flexible bag 42; the hanging member 41 is detachably installed on the support rod 03, and a draw rope 43 capable of shrinking the opening of the breathable flexible bag 42 is arranged at the opening of the breathable flexible bag 42, and the draw rope 43 can be hung on the hanging member 41. The measuring instrument is placed in the breathable flexible bag 42. Among them, the breathable flexible bag 42 can adopt a gauze structure. When in use, the breathable flexible bag 42 equipped with the measuring instrument can be hung on the corresponding different measuring heights according to the height to be measured, so as to realize the temperature and humidity measurement of different heights in the room. The use of a breathable flexible bag 42 to place the measuring instrument can not only ensure that the indoor air can pass through the breathable flexible bag 42 to ensure the measurement effect, but also achieve flexible wrapping to prevent the outer surface of the measuring instrument from being worn; at the same time, the breathable flexible bag 42 can prevent dust from falling on the surface of the measuring instrument.
