Description

Technical Field

[0001] This application relates to the field of building wall testing technology, and in particular to a device for monitoring the heat transfer coefficient of a wall. Background Technology

[0002] For on-site monitoring of wall heat transfer coefficients, a common method is to use a heat box to uniformly heat the indoor wall surface in a specific area to overcome the influence of fluctuating weather conditions on the heat transfer process between the inner and outer sides of the wall. Wall heat transfer coefficient monitoring devices come in two types: wireless and wired. The wireless method involves a wireless data acquisition unit connected to the heat box, which then transmits the signal to the detector, facilitating direct on-site installation and debugging. However, both wired and wireless methods share a common drawback: the heat box is supported by diagonal braces and pressed tightly against the wall. During continuous monitoring, on-site construction or floor vibrations can cause the diagonal braces to shift, creating gaps for hot and cold air exchange between the heat box and the wall, potentially leading to inaccurate test results. Utility Model Content

[0003] To improve the problem of inaccurate test results caused by unstable adhesion between the heat box and the wall, this application provides a wall heat transfer coefficient monitoring device.

[0004] The wall heat transfer coefficient monitoring device provided in this application adopts the following technical solution:

[0005] A wall heat transfer coefficient monitoring device includes a heat box body, a base, and a diagonal brace; a limiting hole is formed on the surface of the heat box body; the base is used to support the heat box body; the diagonal brace is hinged to the base, and a limiting rod is threadedly connected to one end of the diagonal brace that is hinged to the base away from itself; when the limiting rod is inserted into the limiting hole, the heat box body is in close contact with the wall surface.

[0006] By adopting the above technical solution, the base not only provides a support platform for the heat chamber body but also provides a stable support point for the diagonal braces, improving the stability of the heat chamber body's fit against the wall. Compared to the current fixing method relying solely on diagonal braces, the hinged connection between the base and the diagonal braces not only improves the support stability of the diagonal braces but also, through the threaded connection between the limiting rod and the diagonal braces, further tightens the diagonal braces, forcing the heat chamber body to fit tightly against the wall. This reduces gaps in the heat chamber and wall for hot and cold air exchange. The combined weight of the heat chamber body and the base ensures that the diagonal braces can stably support the heat chamber body during on-site construction or floor vibrations, improving the problem of inaccurate test results caused by unstable fit between the heat chamber and the wall.

[0007] Optionally, the base includes a base plate, a first telescopic leg, and a second telescopic leg; both the first telescopic leg and the second telescopic leg are connected to the base plate.

[0008] By adopting the above technical solution, the introduction of the first telescopic leg and the second telescopic leg allows the base to be raised or lowered, making it easy to adjust and fix the height of the hot box body on the wall.

[0009] Optionally, the base plate includes a support plate and a movable plate; the hot box body abuts against the support plate; the first telescopic leg is connected to the support plate; the movable plate is hinged to the support plate, and the diagonal brace is hinged to the movable plate; the second telescopic leg is detachably connected to the movable plate.

[0010] By adopting the above technical solution, the base can be compressed and folded as a whole, making it easy to transport and store.

[0011] Optionally, a hook is connected to the support plate for placing the second telescopic leg.

[0012] By adopting the above technical solution, the introduction of hooks facilitates the storage of the second telescopic leg and the hanging of heavy objects, such as bags containing objects, thereby improving the support stability of the base for the heating box body.

[0013] Optionally, it also includes a lid; the lid is detachably connected to the support plate, and when the lid is connected to the support plate, the lid and the support plate combine to form a lid for closing the hot box body, and the diagonal brace, the movable plate, the first telescopic leg and the second telescopic leg can all be stored inside the lid.

[0014] By adopting the above technical solution, the introduction of the cover allows the base and diagonal brace to be folded and stored inside the cover. After the cover is closed with the hot box body, the entire structure can be stored, making it easy to transport as a whole.

[0015] Optionally, the surface of the movable piece is provided with a slot for the cover to be inserted; when the cover is inserted into the slot, the cover leans against the hot box body at an angle, and the inclined support and the limiting rod are both located inside the cover.

[0016] By adopting the above technical solution, the design of the slot not only secures the lid that leans against the heat box body, but also forces the heat box body to fit tightly against the wall. On the other hand, the lid can firmly cover the diagonal brace, reducing the risk of the diagonal brace being moved by humans during continuous monitoring operations.

[0017] Optionally, the movable piece has a placement area for placing the detector.

[0018] By adopting the above technical solution, it is easier for testing personnel to place the testing instrument, and the problem of loose data interface or data interruption caused by human movement due to random placement of the testing instrument is improved.

[0019] Optionally, a rubber pad is provided on the surface of the base away from the hot box body.

[0020] By adopting the above technical solutions, the risk of base movement caused by on-site construction or floor vibration can be reduced.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] Compared to the current fixing method that relies solely on diagonal braces, the hinged connection between the base and the diagonal braces not only improves the support stability of the diagonal braces, but also, the threaded connection between the limiting rod and the diagonal braces further locks the diagonal braces, forcing the hot box body to be in close contact with the wall, reducing the gaps between the hot box and the wall for the exchange of hot and cold air. With the added weight of the hot box body and the base, the diagonal braces can stably support the hot box body regardless of on-site construction or floor vibration, improving the problem of inaccurate test results caused by unstable contact between the hot box and the wall.

[0023] The slot design not only secures the cover that leans against the hot box body, further forcing the hot box body to fit tightly against the wall, but also allows the cover to firmly cover the diagonal brace, reducing the risk of the diagonal brace being moved by humans during continuous monitoring operations.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a wall heat transfer coefficient monitoring device.

[0032] Reference Figure 1 A wall heat transfer coefficient monitoring device includes a heat box body 1, a base 2, diagonal supports 3, and a cover 4. The heat box body 1 is connected to a wireless data acquisition device 5. The side of the heat box body 1 connected to the wireless data acquisition device 5 is defined as the top surface of the heat box body 1, the side away from the wireless data acquisition device 5 is defined as the bottom surface of the heat box body 1, and the side away from contact with the wall is defined as the back surface of the heat box body 1. The base 2 supports the heat box body 1. Two diagonal supports 3 are provided, both hinged to the base 2. The cover 4 houses the base 2 and the diagonal supports 3.

[0033] Reference Figure 2 and Figure 3 Specifically, the base 2 includes a support plate 21, a movable plate 22, two first telescopic legs 23, and a second telescopic leg 24. The bottom surface of the heating box body 1 abuts against the support plate 21, and the length and width of the support plate 21 are the same as the length and width of the bottom surface of the heating box body 1. Both first telescopic legs 23 are fixed to the support plate 21. The movable plate 22 is hinged to the support plate 21, and the diagonal brace 3 is hinged to the movable plate 22. The second telescopic leg 24 is detachably connected to the movable plate 22. The detachable connection method can be a threaded connection, a plug-in connection, or a bolt connection, etc., which is not limited in this embodiment. Rubber pads 6 are glued and fixed to the bottom of both the first telescopic leg 23 and the second telescopic leg 24 to reduce the risk of the base 2 moving.

[0034] Reference Figure 3 The support plate 21 has two hooks 7 fixed between the two first telescopic legs 23. The hooks 7 are used for placing and storing the second telescopic leg 24. The introduction of the hooks 7 also makes it easier to hang heavy objects, such as bags containing objects, thereby improving the support stability of the base 2 on the heating box body 1.

[0035] Reference Figure 3 It should be noted that the opening of hook 7 faces the hinge position of the support plate 21 and the movable plate 22. The significance of this design is that when the second telescopic leg 24 is placed and stored on hook 7, and the movable plate 22 is flipped relative to the support plate 21, the movable plate 22 moves closer to hook 7, closing the opening of hook 7 and reducing the risk of the second telescopic leg 24 falling off hook 7.

[0036] Reference Figure 4 It is worth noting that the size of the movable piece 22 is limited, and the movable piece 22 is located between the two diagonal supports 3, leaving a placement area for the detector.

[0037] Reference Figure 4The diagonal brace 3 is hinged to the movable plate 22 at one end and threadedly connected to a limiting rod 8. A limiting hole 11 is provided on the back of the heat box body 1. When the heat box body 1 is placed on the support plate 21 and the limiting rod 8 is inserted into the limiting hole 11, the heat box body 1 is pressed tightly against the wall.

[0038] Reference Figure 1 The cover 4 and the support plate 21 are detachably connected. The detachable connection between the cover 4 and the support plate 21 can be a bolt connection, a pin connection, or a magnetic connection, etc. When the cover 4 and the support plate 21 are connected, the cover 4 and the support plate 21 are combined to form a cover for closing the heating box body 1, and the diagonal brace 3, the movable plate 22, the first telescopic leg 23 and the second telescopic leg 24 can all be stored inside the cover.

[0039] Reference Figure 2 This can be understood as follows: the cover 4 has an opening and a notch, with the opening facing the hot box body 1 and the notch being closed by the support plate 21.

[0040] Reference Figure 4 and Figure 5 The surface of the movable piece 22 is provided with a slot 221 for the edge of the notch of the cover 4 to be inserted. When the cover 4 is inserted into the slot 221, the cover 4 leans against the hot box body 1 at an angle. The diagonal brace 3 and the limiting rod 8 are both located inside the cover 4. Furthermore, when a detector is placed, the detector can also be covered inside the cover 4.

[0041] The implementation principle of the wall heat transfer coefficient monitoring device in this application embodiment is as follows: After separating the cover 4 from the support plate 21, flip the movable plate 22, remove the second telescopic leg 24 and connect it to the movable plate 22 to form the base 2. Adjust the first telescopic leg 23 and the second telescopic leg 24 to determine the height of the heat box body 1 on the wall. After confirmation, place the heat box body 1 on the base 2 and attach it to the wall. Flip the diagonal brace 3 and rotate the limiting rod 8 so that the limiting rod 8 is inserted into the limiting hole 11. The inspector observes whether the data of the detector is reasonable to determine whether the position of the heat box body 1 is correct. After confirmation, place the detector on the movable plate 22 and move the cover 4 to lock it into the slot 221 to cover the detector and the diagonal brace 3 for continuous monitoring.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
