Description

Wall heat transfer coefficient monitoring device Technical Field The application relates to the technical field of building wall detection, in particular to a wall heat transfer coefficient monitoring device. Background The on-site monitoring of the heat transfer coefficient of the wall body generally adopts a hot box to uniformly heat the surface of the wall body on the indoor side of a certain area indoors so as to overcome the influence of meteorological condition fluctuation on the heat transfer process on the inner side and the outer side of the wall body. The wall heat transfer coefficient monitoring device is divided into two modes of wireless connection and wired connection, wherein the wireless connection mode is that a wireless data acquisition device is connected to a hot box, and the wireless data acquisition device sends signals to a detector, so that the on-site direct installation and debugging are facilitated. However, both the wired connection mode and the wireless connection mode have a common disadvantage, the hot box is tightly attached to the wall surface through the support of the diagonal brace, in the continuous monitoring time, the diagonal brace moves during the construction of the site or the vibration of the floor slab, and a gap for exchanging cold air and hot air exists between the hot box and the wall surface, so that the detection result is inaccurate. Disclosure of utility model In order to solve the problem of inaccurate detection results caused by unstable adhesion of a hot box and a wall surface, the application provides a wall heat transfer coefficient monitoring device. The application provides a wall heat transfer coefficient monitoring device which adopts the following technical scheme: The wall heat transfer coefficient monitoring device comprises a hot box body, a base and inclined struts, wherein limit holes are formed in the surface of the hot box body, the base is used for bearing the hot box body, the inclined struts are hinged to the base, limit rods are connected to one ends of the inclined struts, which are far away from the base, in a threaded mode, and when the limit rods are inserted into the limit holes, the hot box body is tightly attached to a wall surface. Through adopting above-mentioned technical scheme, the base not only provides supporting platform for the hot box body, still provides firm strong point for the bracing, improves the laminating stability of hot box body and wall. Compared with the prior fixing mode only by the diagonal bracing, the base and the diagonal bracing are hinged with each other, so that the supporting stability of the diagonal bracing is improved, the limit rod and the diagonal bracing are further locked in a threaded connection mode, the hot box body and the wall surface are forced to be in a close fit state, gaps for cold and hot air exchange between the hot box body and the wall surface are reduced, the weight of the hot box body and the weight of the base are maintained, the hot box body can be stably supported by the diagonal bracing no matter the construction on site or the vibration of the floor slab, and the problem that the detection result is inaccurate due to unstable lamination between the hot box and the wall surface is solved.
