Description

A fire-resistant glass wool board performance testing device Technical Field

[0001] This utility model relates to the field of glass wool board testing technology, specifically to a fireproof glass wool board performance testing device. Background Technology

[0002] Glass wool is a roll of glass wool made by melting glass, fiberizing it, and then curing it with the addition of an adhesive. Glass wool boards have fireproof and heat-insulating properties. After production, its fireproof and heat-insulating effects need to be tested. However, the existing testing devices use an adhesive method to fix the glass wool boards. But as the temperature rises, the adhesiveness will decrease, and the glass wool will easily fall off, which is not conducive to the stable heating of the glass wool. Summary of the Invention

[0003] The purpose of this utility model is to provide a fireproof glass wool board performance testing device that is reasonably designed and easy to use, in order to address the defects and shortcomings of the existing technology, and to effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a test chamber, a cover plate, and partitions; the top wall of the test chamber is provided with a cover plate, and several partitions are equidistantly arranged inside the test chamber; the front and rear side walls of the partitions are respectively fixed to the front and rear inner walls of the test chamber; it further comprises:

[0005] The fire pit is located inside the test chamber and below the partition. The front side of the fire pit passes through the front side wall of the test chamber and is set on the same plane as the front side wall of the test chamber. Several through holes are evenly spaced on the perimeter wall of the test chamber, and the through holes are located between the fire pit and the partition.

[0006] The sliding blocks are a plurality of each other and are symmetrically arranged in pairs on the left and right inner walls of the test chamber and on the left and right sides of the partition. Several sliding grooves are provided at equal intervals from front to back on the left and right inner walls of the test chamber and the side walls of the partition. The sliding blocks are slidably arranged in cooperation with the sliding grooves.

[0007] The fixing frame consists of several fixing frames, all of which are arranged in an "L" shape. The vertical plates of the fixing frame are fixed to the side wall of the sliding block one by one. The upper side of the horizontal plate of the fixing frame is provided with a pressure plate. One side of the pressure plate is slidably mounted on the slide groove on the vertical plate of the fixing frame by a slider. The lower side of the slider is connected to the inner bottom wall of the fixing frame by a tension spring.

[0008] The fire extinguishing mechanism is located inside the peripheral wall of the test chamber and is connected to the cover plate.

[0009] Using the above technical solution, the glass wool board is inserted into two symmetrical fixed frames. Then, the pressure plate is released, and the elastic force of the tension spring causes the pressure plate to move downward until it contacts the glass wool board, thus clamping the glass wool board. Then, the sliding block on the fixed frame slides into the corresponding sliding groove, so that the glass wool board is located in the test chamber. Then, an open flame is lit and placed in a fire pit, and then inserted into the test chamber. The open flame heats the glass wool board. When the glass wool board shows signs of burning, it indicates that the fire resistance is unqualified; if it does not show signs of burning, it indicates that the fire resistance is qualified. Then, a temperature sensor is placed on the upper side of the glass wool board to test the thermal insulation performance. After the test is completed, the fire is extinguished by a fire extinguishing mechanism.

[0010] As a further improvement of this utility model, a handle is fixed on the front side wall of the fire pit, and a heat insulation ring is fitted on the outside of the handle; this makes it easy to pull the fire pit out of the test box, while avoiding burns to the user when inserting and pulling out the fire pit.

[0011] As a further improvement of this utility model, an observation window is provided in the opening on the front side wall of the test box, and the observation window is located above the through hole.

[0012] The above technical solution facilitates the observation of glass wool boards during measurement.

[0013] As a further improvement of this utility model, the fire extinguishing mechanism includes:

[0014] The sealing frame is set inside the peripheral wall of the test chamber. The sealing frame is inserted into the through hole. The four corners of the top wall of the sealing frame are fixed with screws. The upper end of the screw passes through the top wall of the test chamber and is fixedly connected to the lower side wall of the cover plate.

[0015] The internally threaded tubes consist of four tubes, each threaded onto a screw rod. The internally threaded tubes are screwed onto the upper side of the test chamber's circumferential wall via bearings. The four internally threaded tubes are connected by a synchronous wheel drive assembly.

[0016] The drive motor is embedded and fixed on the upper side of one side wall of the test box. A gear is fixed on the output shaft of the drive motor, and the gear meshes with the tooth groove on the outer ring wall of one of the internal threaded tubes.

[0017] The above technical solution involves starting a drive motor, which in turn drives a gear to rotate. The gear then drives a meshing internally threaded tube to rotate. This internally threaded tube, through a synchronous gear transmission assembly, drives three other internally threaded tubes to rotate. Each internally threaded tube moves up and down via its internal screw. The screw drives the sealing frame and cover plate upwards, facilitating the placement of the glass wool board into the test chamber for measurement. When fire extinguishing is required, the drive motor is started in reverse, causing the screw to drive the sealing frame and cover plate downwards until the sealing frame is engaged in the through hole and the cover plate abuts against the top wall of the test chamber, thus sealing the test chamber and achieving the fire extinguishing effect.

[0018] As a further improvement of this utility model, sealing gaskets are fixed on the inner and outer side walls of the sealing frame and the lower surface of the cover plate.

[0019] The above technical solution can improve the sealing performance between the sealing frame and the cover plate and the test chamber.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The fireproof glass wool board performance testing device of this utility model can position the glass wool board without adhesion, and at the same time, the fixed position can be adjusted according to the length of the glass wool board, which improves the stability during measurement. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

[0031] Sliding blocks 5, there are several sliding blocks 5, and they are symmetrically arranged in pairs on the left and right inner walls of the test chamber 1 and the left and right sides of the partition 3. Several sliding grooves 1-2 are equally spaced from front to back on the left and right inner walls of the test chamber 1 and the side walls of the partition 3. The sliding blocks 5 are slidably arranged in cooperation with the sliding grooves 1-2.

[0032] The fixing frame 6 consists of several units, all of which are arranged in an "L" shape. The vertical plates of the fixing frame 6 are welded and fixed to the side wall of the sliding block 5. The upper side of the horizontal plate of the fixing frame 6 is provided with a pressure plate 7. One side of the pressure plate 7 is slidably mounted on the slide groove on the vertical plate of the fixing frame 6 by a slider. The lower side of the slider is connected to the inner bottom wall of the fixing frame 6 by a tension spring 8.

[0033] Fire extinguishing mechanism 9 is installed within the perimeter wall of the test chamber 1 and is connected to the cover plate 2. Example 2:

[0034] Referring to Figures 2 and 4-5, based on Embodiment 1, the fire extinguishing mechanism 9 includes:

[0035] A sealing frame 9-1 is installed inside the peripheral wall of the test chamber 1. The sealing frame 9-1 is inserted into the through hole 1-1. Screws 9-2 are welded and fixed at the four corners of the top wall of the sealing frame 9-1. The upper end of the screws 9-2 passes through the top wall of the test chamber 1 and is fixedly connected to the lower side wall of the cover plate 2. Sealing gaskets 13 are glued and fixed on the inner and outer side walls of the sealing frame 9-1 and the lower surface of the cover plate 2, which can improve the sealing performance between the sealing frame 9-1, the cover plate 2 and the test chamber 1.

[0036] There are four internally threaded tubes 9-3, and each of them is threaded onto the screw 9-2. The internally threaded tubes 9-3 are screwed onto the upper side of the inner wall of the test chamber 1 through bearings. The four internally threaded tubes 9-3 are connected to each other through a synchronous wheel transmission assembly.
