Description

Technical Field

[0001] The invention belongs to the technical field of building temperature control experiments, and specifically relates to an experimental device and method for testing the temperature control effect of reflective materials. Background Art

[0002] The temperature control effect experiment of reflective materials focuses on its effect on heat transfer under different temperature conditions, especially its heat insulation and reflection performance. It mainly tests the heat insulation performance of reflective materials to evaluate the ability of reflective materials to reduce heat transfer in high temperature environments. At the same time, it verifies the reflective performance of reflective materials to test the reflective effect of reflective materials on solar radiation heat and their role in reducing the surface temperature of objects.

[0003] In order to study the temperature control effect of reflective materials, different materials are used in the prior art to test them under the sun. In order to conduct the test effectively, the test materials need to be placed in a high and unobstructed place for testing. However, this test method requires the reflective material to be disassembled and assembled from the high bracket when different reflective materials need to be replaced. The entire disassembly and assembly process is relatively complicated, which affects the test efficiency.

[0004] At the same time, during the testing of reflective materials, due to different testing environments, the lighting angle will change to a certain extent within a day. In order to effectively test the temperature control effect of reflective materials, it is necessary to frequently change the position of reflective materials to meet the experimental requirements. The overall testing process is relatively complicated and urgently needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide an experimental device and method for testing the temperature control effect of reflective materials, so as to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an experimental device for testing the temperature control effect of reflective materials, comprising a base, a test box assembly is arranged above the base, hinges are installed at equal intervals between the front end of the base and the front end of the test box assembly, the test box assembly rotates relative to the base, an angle adjustment assembly is fixedly installed in the middle of the rear end of the base, the front end of the angle adjustment assembly is connected to the middle of the rear end of the test box assembly, scales are installed on the left and right sides of the front end of the base, casters are installed at the bottom of the base near the outer side surface, and a leveling bolt is installed in the middle of the bottom of the base near the front side.

[0007] Before use, you need to prepare a variety of reflective materials to be tested, and a temperature sensor is built into the test box assembly to monitor the temperature of each reflective material when exposed to light. The device is moved to a high, unobstructed place via casters, and the base is ensured to be level by adjusting the leveling bolts to complete the preparations before the experiment.

[0008] As a further technical solution of the present invention, the test box assembly includes a test installation box, a front end of the test installation box is connected to a hinge, and a middle portion of a rear end of the test installation box is connected to an angle adjustment assembly.

[0009] As a further technical solution of the present invention, the bottom of the test installation box is provided with installation grooves in a matrix shape, and limiting ear plates are installed near the four corners of the bottom of the test installation box, and limiting frames are provided on the left and right sides of the bottom of the installation grooves.

[0010] As a further technical solution of the present invention, the front and rear ends of the two limit frames are movably connected with the limit ear plates, the limit frames are displaced left and right relative to the limit ear plates, and positioning magnets are installed at the relatively close ends of the two limit frames.

[0011] As a further technical solution of the present invention, when the distance between the two limit frames is the minimum, the two positioning magnets are attracted to each other, and the two limit frames block the bottom ends of all installation slots, and a pull rod is fixedly installed on the relatively distant side of the two limit frames.

[0012] When different reflective test materials need to be installed, the two pull rods can be pulled to the left and right to move the two limit frames away from each other. At this time, the adsorption and fixation between the two positioning magnets can be released until the positioning magnet moves to one side of the limiting ear plate. At this time, there will be no obstruction at the bottom of all installation slots, and the corresponding reflective material can be installed in the corresponding installation slot. After the installation is completed, the pull rod can be pushed toward the middle to make the two positioning magnets adsorb again, and the limit frame can be used to completely block the bottom of the installation slot to complete the material installation process.

[0013] By opening a plurality of installation slots at the bottom of the test installation box and using two relatively located limit frames, the reflective material can be quickly installed into the inside of the installation slot and can be quickly disassembled. No complicated disassembly steps are required during the entire disassembly and assembly process. The different performances of various reflective materials under light can be effectively tested, which significantly improves the test efficiency and can quickly find suitable reflective materials for the building's cooling process.

[0014] As a further technical solution of the present invention, the angle adjustment assembly includes a mounting seat, the front end of the mounting seat is connected to the middle of the rear end of the base, the top end of the mounting seat is fixedly connected to a fixed guide rail, the rear end of the fixed guide rail is fixedly installed with a reinforcing rib, and the bottom end of the reinforcing rib is connected to the top of the mounting seat.

[0015] As a further technical solution of the present invention, the outer side surface of the fixed guide rail is movably connected with a guide block, both sides of the guide block penetrate the outer side surface of the fixed guide rail and are fixedly connected with a threaded sleeve located inside the fixed guide rail, and the guide block moves up and down relative to the fixed guide rail.

[0016] As a further technical solution of the present invention, a screw rod is movably connected to the middle part of the fixed guide rail, and the screw rod rotates relative to the fixed guide rail. The outer side surface of the screw rod is threadedly connected to the inner side surface of the threaded sleeve, and the top end of the screw rod passes through the top end of the fixed guide rail and is fixedly connected to a turntable.

[0017] As a further technical solution of the present invention, a first fixed seat is fixedly installed at the front end of the guide block, and the end of the first fixed seat away from the guide block is movably connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and the front end of the second fixed seat is connected to the middle part of the rear side of the test installation box.

[0018] When the angle of sunlight changes, the turntable can be rotated to drive the screw to rotate. At this time, under the action of the thread of the threaded sleeve and the guiding action of the guide block and the fixed guide rail, the guide block can be driven to move up and down, and the first fixed seat can be driven to move up and down at the same time. When the guide block moves downward, the connecting rod can be driven to deflect in the direction away from the fixed guide rail and apply thrust to the test box assembly. At this time, the test box assembly can rotate relative to the base, that is, the angle between the test box assembly and the base support foot increases accordingly. Conversely, when the guide block moves upward, the angle between the test box assembly and the base decreases accordingly, completing the angle adjustment process of the test box assembly to adapt to the change of sunlight angle.

[0019] By utilizing an adjustable angle adjustment component and a movable connection between the test box component and the base, the device can quickly adjust the angle of the test box component by rotating the turntable and complete self-locking. The entire adjustment process is relatively simple, avoiding the problem of traditional devices needing to change the position of reflective materials when facing different lighting angles. Rapid adjustment can be achieved, thereby improving overall test efficiency.

[0020] A method for testing an experimental device for the temperature control effect of a reflective material comprises the following steps:

[0021] S1: Before the test, pull the rod to the left and right sides respectively to release the adsorption between the two positioning magnets, so that the two limit frames can be driven away from each other until all the installation slots are completely exposed, and the corresponding reflective material can be stuck inside the installation slot. After the installation is completed, push the rod toward the middle until the two positioning magnets are adsorbed to each other, and the limit frame can block the bottom of the installation slot;

[0022] S2: After the reflective material is installed, the device is moved to a high place and faces the sun. When sunlight shines on the reflective material, the light is reflected by the material, thereby reducing the direct solar radiation to the surface of the building. At the same time, the temperature of the material is recorded by an external temperature sensor to draw a temperature change curve;

[0023] S3: When the angle of sunlight changes, the turntable is rotated to drive the guide block to move up and down relative to the fixed guide rail under the action of the threaded sleeve, and the first fixed seat at the front end is driven to move up and down. When the guide block moves upward, a pulling force can be applied to the connecting rod. At this time, the connecting rod can be deflected in the direction close to the fixed guide rail, and a pulling force is applied to the test box assembly. At this time, the test box assembly can be rotated in the direction close to the base, and the angle between the test box assembly and the base is reduced, completing the angle adjustment process.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention provides a plurality of installation slots at the bottom of the test installation box, and uses two relatively located limit frames to enable the reflective material to be quickly installed into the interior of the installation slot, and can be quickly disassembled. No complicated disassembly steps are required during the entire disassembly process, and the different performances of various reflective materials under light can be effectively tested, which significantly improves the test efficiency, and can quickly find suitable reflective materials for the cooling process of the building.

[0026] 2. The present invention utilizes an adjustable angle adjustment component and a movable connection between the test box component and the base, so that the device can quickly adjust the angle of the test box component by rotating the turntable and complete self-locking. The entire adjustment process is relatively simple, avoiding the problem of traditional devices needing to change the position of the reflective material when facing different lighting angles, and can achieve rapid adjustment, thereby improving the overall test efficiency.

[0045] A method for testing an experimental device for the temperature control effect of a reflective material comprises the following steps:
