Traditional thermal insulation materials include fiberglass, asbestos, rock wool, and silicates, while newer thermal insulation materials include aerogel felt and vacuum panels. They are used in building envelopes or thermal equipment, and as materials or material composites that impede the transfer of heat.

[0004] Currently, traditional hydrophobicity calibration and testing instruments for thermal insulation materials cannot determine whether there are any abnormalities in the insulators when testing hydrophobicity, nor can they predict whether there will be any dangers when spraying water on live insulators. In addition, the nozzle adjustment of existing equipment is inconvenient, resulting in many inconveniences and limitations in use. Utility Model Content

In the process of testing the hydrophobicity of thermal insulation materials, the instrument cannot determine whether there is any abnormality in the insulator, cannot predict whether there will be any danger in spraying water on the live insulator, and the existing equipment has inconvenient nozzle adjustment, resulting in many inconveniences and limitations in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calibration and testing instrument for the hydrophobicity of thermal insulation materials, comprising a base, support blocks arranged around the lower end of the base, a support frame arranged at the upper end of the base, a fixing bolt threaded to the bottom wall of the support frame, positioning sleeves fixedly connected to both sides of the upper end of the support frame, a fixing mechanism detachably connected to the upper end of the positioning sleeves, an adjustment mechanism fixedly connected to one side of the upper end of the base, a spray liquid tank fixedly connected to one side of the adjustment mechanism, and a delivery pipe connected to the rear end of the spray liquid tank;

[0008] Preferably, the upper end of the support block is fixedly connected to the lower end of the base around the perimeter, and the lower end of the support frame is detachably connected to the upper end of the base.

[0009] Preferably, the top side of the inner wall of the placement box is fixedly connected to the outer wall of the support plate, and the two sides of the support plate are slidably connected to the outer wall of the slide rod.

[0010] Preferably, the outer wall of the positioning screw penetrates the inner wall of the positioning sleeve and extends to one side thereon.

[0011] Preferably, the adjusting mechanism includes a vertical rod, the lower end of which is fixedly connected to one side of the upper end of the base. A displacement block is provided on the outer wall of the vertical rod. An adjusting component is provided at both the front and rear ends of the displacement block.

[0013] Preferably, the inner wall of the nozzle is inserted into the outer wall of one end of the delivery pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The fixed mechanism allows the equipment to stably fix the insulation material and facilitates the adjustment of the insulation material's position, thus enabling convenient calibration testing of the insulation material hydrophobicity tester. Specifically, the positioning screw and positioning sleeve work together to fix and disassemble the placement box, making it easy to place the insulation material into the placement box. By rotating the handle, the screw is driven to rotate, which in turn moves the clamping plate downward, thereby clamping and fixing the insulation material. The rubber pad increases the friction between the clamping plate and the insulation material, improving the stability of the fixation. At the same time, the sliding rod limits the movement of the support plate, ensuring that the support plate can only move along the direction of the sliding rod and guaranteeing the stability of the clamping plate's movement.

[0016] 2. The adjustable mechanism allows the equipment to flexibly adjust the nozzle according to the size and shape of the insulation material, ensuring that the spray liquid can evenly cover the surface of the insulation material, thus improving the accuracy and efficiency of the test. Specifically, the sliding of displacement block one on the vertical rod and displacement block two on the horizontal rod enables the nozzle to be freely adjusted in three-dimensional space. The setting of adjustment component one and adjustment component two can fix the position of displacement block one and displacement block two, ensuring that the position of the nozzle will not change during the test. The setting of the liquid injection port facilitates the injection of spray liquid into the nozzle through the delivery pipe, making the operation simple and convenient. Attached Figure Description
