Description

Technical Field

[0001] The present invention relates to the technical field of heat conduction testing equipment, and particularly relates to a heat conduction testing equipment for building energy conservation detection. Background Art

[0002] As is well known, building energy conservation detection is an activity to detect and evaluate the energy utilization efficiency of buildings and the implementation of energy conservation measures, aiming to ensure that buildings meet energy conservation standards, reduce energy consumption, and improve energy utilization efficiency. In building energy conservation detection, heat conduction testing is a very important link. To facilitate the heat conduction testing of building energy conservation detection, we propose a heat conduction testing equipment for building energy conservation detection.

[0003] After retrieval, the patent with Chinese Patent Publication No. CN117110371A and the patent with Chinese Patent Publication No. CN115728346A respectively disclose a heat conduction testing equipment for building energy conservation detection and a heat conduction testing device. The former is generally described as including a hexagonal mounting plate, with an outer mounting frame fixedly connected to the top edge of the hexagonal mounting plate. An inner mounting frame is fixedly connected to the top of the hexagonal mounting plate corresponding to the inner side of the outer mounting frame. A multi-angle synchronous detection mechanism is arranged on the top of the hexagonal mounting plate, which is used to synchronously detect multiple groups of building materials and quickly adjust the temperature inside the equipment during the start and end of the detection. The multi-angle synchronous detection mechanism includes a central high-temperature barrel, with a central high-temperature barrel mounted on the top of the hexagonal mounting plate. A central heating rod is fixedly installed in the middle of the inner side of the central high-temperature barrel. Two bottom heat conduction pumps are connected to both sides of the central high-temperature barrel. The ends of the two bottom heat conduction pumps are connected to a bottom distribution pipe. Inner detection boxes are installed on each side of the inner mounting frame. The side of the bottom distribution pipe is connected to a telescopic heat conduction box. The side of the telescopic heat conduction box is connected to a detection inner plate. Two top cooling pumps are installed on both sides of the outer low-temperature barrel. The ends of the two top cooling pumps are connected to a top distribution pipe. The outer side of the top distribution pipe is connected to the two top corners of the corresponding telescopic heat conduction box through pipes. The outer side of the inner mounting frame is connected to an outer mounting sleeve. Clamping rubber strips are bonded to both sides inside the outer mounting sleeve. A detection outer box is installed on the side of the outer mounting frame. A telescopic clamping rod is connected inside the detection outer box. The ends of the four telescopic clamping rods are jointly connected to a detection outer plate. The latter is generally described as including a downward pressing driving device, a base, a downward pressing module, and a heating module. The downward pressing driving device is fixedly connected to the upper end of the base. The downward pressing module is connected to the output end of the downward pressing driving device. The heating module is fixedly connected to the lower end of the base. The downward pressing module and the heating module are both in positioning cooperation with the test product. The downward pressing driving device drives the downward pressing module to press the test product tightly in the heating module, and the heating module emits heat and detects the internal temperature change.

[0004] Although the above two prior art solutions can both form a heat conduction test by supporting module materials, considering the actual building situation, there are still significant differences between detecting small-sized modules such as material samples and actual buildings. The actual building will be affected by multiple factors such as construction and environment.

By applying a heat source to the internal space and then detecting in the external space, the conduction detection of the heat source in the internal space through the target building can be realized, and thus the thermal conduction test for building energy efficiency detection can be realized.

[0046] The temperature sensor 4 and the electromagnet 16 in this embodiment are both conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them without improving their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they follow the requirements of their user manuals, and thus will not be elaborated here.

[0047] In summary, the working principle of the heat conduction test device for building energy conservation detection is as follows: Before use, first install a control circuit for the temperature sensor 4 and the electromagnet 16. The guiding wires of the control circuit can be installed in a guiding manner along with the first towing rope 41 or along with the second towing rope 43. Then, connect a pumping pipe to the air supply hole 7 and connect the pumping pipe to an external air pump. Finally, pre-load a heat-insulating fluid into the first storage box 25. The heat-insulating fluid can be a flowable liquid material or a powder-like solid material. During use, fix both first towing ropes 41 at one end of the target building and fix both second towing ropes 43 at the other end of the target building. When the first towing rope 41 and the second towing rope 43 are fixed relative to the target building, the outer sealing rubber ring 11 should be controlled to fit the test surface of the target building, as shown in the appendix Figure 19Schematic diagram of the first towing rope 41 being installed at a higher or lower position relative to the second towing rope 43. During the installation process of the second towing rope 43, the length of the second towing rope 43 should be controlled so that both the first towing rope 41 and the second towing rope 43 are in a taut state. In this way, with the auxiliary guiding effect of the first guiding bend cylinder 40 and the second guiding bend cylinder 42, the outer sealing rubber ring 11 can form a better fit and compression with the target building. Since the relative distances between the inner rubber ring 12 and the outer sealing rubber ring 11 and the target building are the same, when the outer sealing rubber ring 11 comes into contact with and compresses the target building, contact and compression are also formed between the inner rubber ring 12 and the target building. After that, an independent space isolated from the outside is formed among the inner rubber ring 12, the outer sealing rubber ring 11, the installation outer frame 1, and the target building. Due to the elastic effect of the arc spring 22, the rotation stability of the rotary connecting fabric ring 21 relative to the installation outer frame 1 can be maintained. Therefore, the first storage box 25 is located above the second storage box 26. Without applying driving forces to the first driving rope 44 and the second driving rope 45, under the elastic effects of the two elastic springs 33, the two gates 32 will respectively block the feeding channel 29 and the discharging channel 30. In this state, the heat-insulating fluid in the first storage box 25 will not flow through the feeding channel 29 under its own gravity. Then, by pulling the first driving rope 44, the gate 32 inserted into the feeding channel 29 is withdrawn relative to the feeding channel 29. After that, the blocking effect of the feeding channel 29 fails, and the heat-insulating fluid in the first storage box 25 will flow through the feeding channel 29 under its own gravity and finally enter the independent space formed by the cooperation of the inner rubber ring 12, the outer sealing rubber ring 11, the installation outer frame 1, and the target building, improving the sealing and heat-insulating effect at the contact between the installation outer frame 1 and the target building.

[0048] Further, then, by controlling the energization of the electromagnet 16 to generate an electromagnetic field, and causing the generated electromagnetic field to form a mutually repulsive magnetic force with the permanent magnet 15, under the action of this magnetic repulsive force, the electromagnet 16 will move away from the permanent magnet 15. The moving-away permanent magnet 15 will drive the sliding cylinder 6 to move away from the target building relative to the mounting cylinder 5, realizing the separation of the inner sealing rubber ring 13 from the target building, making the space inside the heat transfer inner frame 2 communicate with the space inside the mounting outer frame 1. To maintain this state of mutual communication, normal-temperature air is pumped into the pumping pipe by an air pump. This normal-temperature air will be dispersed into the four feeding holes 10 through the guidance of the air supply holes 7, and after forming a pressure-maintaining flow inside the heat transfer inner frame 2, it will be discharged outside through the extension pipe 55, the return holes 9, and the return air holes 8, so that the space inside the mutually communicating heat transfer inner frame 2 and the space inside the mounting outer frame 1 have the same temperature. Then, the current passed through the electromagnet 16 is adjusted to form a mutually attractive magnetic force between the electromagnet 16 and the permanent magnet 15. Under the action of this mutually attractive magnetic force, the permanent magnet 15 will move closer to the target building until the inner sealing rubber ring 13 is tightly pressed against and fitted to the target building. Due to the elastic action of the double limit spring 14, when the inner sealing rubber ring 13 is tightly pressed against and fitted to the target building, the double limit spring 14 can maintain and promote the pressing and further tight fitting of the inner sealing rubber ring 13 to the target building, so as to ensure good spatial isolation of the heat transfer inner frame 2 from the target building, and also separate the internal space of the heat transfer inner frame 2 from the internal space of the mounting outer frame 1. Then, high-temperature air is pumped into the heat transfer inner frame 2 by an air pump to increase the temperature inside the heat transfer inner frame 2, and four temperature sensors 4 are started to detect the temperatures of different regions inside the mounting outer frame 1. Both the mounting outer frame 1 and the heat transfer inner frame 2 are made of materials with good heat insulation effects or are coated with heat insulation coatings. Therefore, when the temperature inside the heat transfer inner frame 2 rises, when the heat inside the heat transfer inner frame 2 conducts to the inside of the mounting outer frame 1, it mainly conducts through the target building, as shown in the attached Figure 20 figure. The direction of the curved arrow in this figure indicates the schematic direction of the effective diffusion of heat through the target building. Control the continuous and stable pumping of high-temperature air into the heat transfer inner frame 2, and use the four temperature sensors 4 to detect the temperatures of the four detection points in real time. As time goes by, the heat conduction test of the target building is realized through the temperature rise conditions of the four temperature sensors 4, as shown in the attached Figure 1As shown, the temperature transfer inner frame 2 is eccentrically arranged within the installation outer frame 1, and the four support cylinders 3 are arranged in an axially symmetric and equiangular pattern within the installation outer frame 1. Therefore, the four temperature sensors 4 will have different distances relative to the temperature transfer inner frame 2. During actual testing, if the temperature reading of the temperature sensor 4 that is relatively far from the temperature transfer inner frame 2 among the four temperature sensors 4 is lower than that of the temperature sensor 4 that is closer to the temperature transfer inner frame 2, it indicates that the test data is valid. According to the readings of the temperature sensors 4, when the heat source temperature within the temperature transfer inner frame 2 is the same and the conduction time is the same, the higher the temperature rise change of the corresponding temperature sensor 4, the higher the thermal conduction efficiency of the target building, and the poorer the energy-saving performance of the corresponding target building.

[0049] After the test is completed, stop pumping air into the temperature transfer inner frame 2, and pull the second driving rope 45 to pull out one of the gates 32 near the lower side relative to the discharge channel 30. Thereafter, under the action of gravity, the heat-insulating fluid filled between the outer sealing rubber ring 11 and the inner rubber ring 12 will flow into the second storage box 26. When the flow of the heat-insulating fluid is completed, release the pulling force applied to the second driving rope 45. Thereafter, the gate 32 near the lower side will be re-inserted into the discharge channel 30 to close the discharge channel 30. Then, adjust the positions of the installation outer frame 1 and the temperature transfer inner frame 2 relative to the target building to achieve the corresponding adjustment of the next target building or the next target detection point on the same target building. After the adjustment is completed, since the heat-insulating fluid is collected into the second storage box 26, when it is necessary to refill the heat-insulating fluid into the area between the outer sealing rubber ring 11 and the inner rubber ring 12 again, it is necessary to pull the adjustment traction rope 24 to make the rotary connection cloth ring 21 rotate and adjust relative to the installation outer frame 1 against the arc spring 22, and the rotation angle of this rotation adjustment is 180 degrees. Keep the pulling force applied to the adjustment traction rope 24 to exchange the upper and lower positions of the first storage box 25 and the second storage box 26. Thereafter, pull the first driving rope 44 again to open one of the gates 32 near the upper side, and the heat-insulating fluid in the second storage box 26 can flow out. Similarly, when the heat-insulating fluid is used up, it will be discharged and collected into the first storage box 25. Therefore, the heat-insulating fluid will form an alternating reciprocating storage between the first storage box 25 and the second storage box 26, and finally achieve the reciprocating use and recycling of the heat-insulating fluid. Since the heat-insulating fluid is in contact with the target building during use, there will inevitably be consumption when the heat-insulating fluid is recycled. Therefore, the heat-insulating fluid initially added to the first storage box 25 should be greater than the amount of heat-insulating fluid required for a single use, and as the heat-insulating fluid is consumed during use, the heat-insulating fluid should be supplemented periodically.
