Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation board detection, in particular to a thermal conductivity detection device for a building thermal insulation board. Background Art

[0002] Thermal conductivity is one of the important parameters used to measure the thermal insulation performance of thermal insulation materials. It is a key indicator for measuring and identifying the thermal insulation capacity of thermal insulation boards. Among them, high-performance gel glass bead composite polystyrene particle thermal insulation board is an environmentally friendly thermal insulation material. In the field of building insulation, the use of this thermal insulation material can effectively improve the thermal insulation performance of buildings, reduce building energy consumption, and thus reduce the impact on the environment. Therefore, the accurate measurement of the thermal conductivity of thermal insulation boards has important practical significance in modern production. At the same time, thermal insulation boards require detection devices to complete the detection of thermal conductivity in order to determine the stability of the thermal insulation boards.

[0003] A thermal conductivity detection device suitable for insulation boards of various specifications is disclosed in a patent application with reference publication number CN215375192U. The detection device pushes the cold plate toward the hot plate through a downward pressure cylinder, thereby pressing the insulation board between the cold plate and the hot plate. Subsequently, the thermal conductivity of the insulation board is detected through the cooperation of the hot plate and the cold plate, and the thermal conductivity of the insulation board is obtained through an external control system.

[0004] The above detection device can well complete the thermal conductivity test of the insulation board by pressing and fitting the cold plate and the hot plate. However, after the actual test, a large amount of residual temperature will remain on the surface of the hot plate and the cold plate, which is very likely to interfere with the subsequent measurement of the insulation board and cause a decrease in the detection accuracy of the insulation board. Therefore, the hot plate and the cold plate need to be cooled before subsequent detection work is carried out, which reduces the detection efficiency of the detection device and is inconvenient for operators to use.

[0005] At the same time, the current detection device has a poor cooling effect on hot plates and cold plates, a slow cooling speed, and reduced heat dissipation efficiency, which requires a lot of time and is not conducive to the rapid detection of subsequent insulation boards, increasing the limitations of the detection device.

[0055] It is worth noting that when the insulation board body 405 is restricted: by providing a restriction mechanism, the telescopic member 322 normally extends the telescopic sleeve 321, and the two sides of the insulation board body 405 are restricted by the two telescopic members 322, so that the insulation board body 405 will not fall in the concave furnace rack 401, which is conducive to the subsequent clamping and fixing of the cold plate 404 and the hot plate 403, and the initial position of the two telescopic members 322 can be adjusted. It only needs to turn the hand wheel 31 to drive the positive and negative threaded screws 28 to complete the rotation, and the two No. 2 screw nuts 29 are linked to each other. The two telescopic members 322 are close to each other and away from each other, and then the spacing between the two telescopic members 322 is adjusted, which can adapt to the insulation board bodies 405 of different sizes to complete the restriction work, and has strong adaptability. In addition, inclined surfaces 324 are arranged on the side walls of the two telescopic members 322, so that the cold plate 404 and the hot plate 403 are respectively in contact with the inclined surfaces 324 of the two telescopic members 322 on the clamping path and complete the downward pressure, so that the telescopic member 322 is contracted into the telescopic sleeve 321, that is, when the cold plate 404 and the hot plate 403 are on the path close to each other, the contact area between the telescopic member 322 and the insulation board body 405 is gradually increased. The two are alternately completed, so that the insulation board body 405 always remains stable, reducing the difficulty of clamping, and under the restriction of the one-way bearing 36, when the telescopic member 322 moves down, the power will not be transmitted to the friction wheel 35. In this path, the friction wheel 35 does not rotate. After the subsequent detection is completed, the cold plate 404 and the hot plate 403 move away from each other. Under the push of the reset spring 323, the telescopic member 322 is driven to extend the telescopic sleeve 321 again and contact the insulation board body 405 to complete the restriction again. When the telescopic member 322 extends, the guide The rack 34 is meshed with the traveling gear 37, and the one-way bearing 36 is locked at this time, driving the friction wheel 35 to complete the rotation. Since the friction wheel 35 is in contact with the insulation board body 405, the insulation board body 405 is pushed out from the concave grate 401 by the rotation of the friction wheel 35, which is convenient for operators to take and inspect. At the same time, the two friction wheels 35 are staggered, so that the two telescopic members 322 can respectively drive the two friction wheels 35 to push the insulation board body 405, thereby improving the stability of pushing the insulation board body 405.

[0056] In the embodiment of the present invention, the two blocking members 32 both include a telescopic sleeve 321, which is detachably fixedly connected to the second screw nut 29, and the topmost plane of the telescopic sleeve 321 is lower than the topmost plane in the fine-tuning area 27. A telescopic member 322 is slidably engaged in the telescopic sleeve 321, and guide areas cooperating with the telescopic member 322 are provided on both sides of the telescopic sleeve 321. The telescopic member 322 can be retracted into the telescopic sleeve 321 to complete the avoidance. A return spring 323 is installed between the telescopic sleeve 321 and the telescopic member 322, and the return spring 323 pushes the telescopic member 322 to extend out of the telescopic sleeve 321. The two telescopic members 322 are both provided with inclined surfaces 324 on the side facing the cold plate 404 and the hot plate 403. The two telescopic members 322 complete the active avoidance with the cold plate 404 and the hot plate 403 through the inclined surfaces 324, and the active restriction of the insulation board body 405 is completed by the two telescopic members 322 extending out of the fine-tuning area 27.

[0057] In the embodiment of the present invention, a sliding area 33 is recessed inwardly on the opposite sides of the two telescopic members 322, and the sliding areas 33 on the two telescopic members 322 are staggered front and back in the fine-tuning area 27, a guide rack 34 is installed on one side of the inner wall of the two sliding areas 33, and a friction wheel 35 is rotatably installed on the opposite sides of the two telescopic sleeves 321. At the same time, a ratchet and pawl mechanism can be installed between the friction wheel 35 and the telescopic sleeves 321 as needed, and the ratchet and pawl mechanism is used to limit the rotation direction of the friction wheel 35. The two friction wheels 35 are staggered front and back in the fine-tuning area 27, and the two friction wheels 35 are in friction contact with the insulation board body 405, and the top of the friction wheel 35 is flush with the top of the fine-tuning area 27, and the friction pads of different thicknesses are added to the friction wheel 35. The friction contact with the insulation board body 405 can also be completed by other means. A one-way bearing 36 is installed on the side of the two friction wheels 35 facing the slip zone 33, and a traveling gear 37 is installed on the one-way bearing 36. The traveling gear 37 is meshed with the guide rack 34. The extension of the telescopic part 322 in the telescopic sleeve 321 drives the two friction wheels 35 to complete the pushing action on the insulation board body 405. When the two telescopic parts 322 are extended in the telescopic sleeve 321, the two one-way bearings 36 complete the locking and drive the two friction wheels 35 to rotate to push the insulation board body 405 to perform the unloading action. When the two telescopic parts 322 are retracted in the telescopic sleeve 321, the two one-way bearings 36 complete the unlocking and complete the transmission to the two friction wheels 35.

[0058] The present invention provides a device for detecting thermal conductivity of a building insulation board, and the specific working principle is as follows: first, the insulation board body 405 is sent into the detection cabinet 1, and the package detection of the insulation board body 405 is completed by the detection furnace 4, and the control unit controls the cold plate 404 and the hot plate 403 to complete the detection work, so as to obtain the thermal conductivity of the insulation board body 405, which is conducive to the subsequent improvement and upgrading of the insulation board body 405.

[0059] By arranging a limiting mechanism in the detection furnace 4, the limiting mechanism can complete the preliminary limiting of the insulation board body 405 when the cold plate 404 and the hot plate 403 are unfolded, so that the insulation board body 405 is stable, which is conducive to the subsequent cold plate 404 and the hot plate 403 to complete the stable clamping of the insulation board body 405, and the limiting mechanism can be linked with the cold plate 404 and the hot plate 403 to complete active avoidance, avoiding interference with the cold plate 404 and the hot plate 403, and the limiting mechanism can adapt to the insulation board body 405 of different thicknesses to complete size adjustment, which is conducive to fine-tuning by the operator, and expands the adaptability of the detection device;
