Description

Technical Field

[0001] The utility model relates to the technical field of glass static pressure resistance testing, in particular to a multi-cavity glass static pressure resistance testing device. Background Art

[0002] At present, the water storage bags used for glass static pressure resistance testing on the market generally have only one cavity. During the test, the water storage bag needs to be placed on the glass and then water is added to the water storage bag. As the water is injected, the tested glass will bend under the action of gravity. At this time, the water will gather at the curved part, causing it to bend more and more under pressure, gradually presenting a "bowl-shaped" structure, such as Figure 1 shown.

[0003] This directly results in uneven force on the glass. Furthermore, because the bottom of the water bag bends with the glass, inaccurate control of the water level in the bag can affect the accuracy of the test results. Specifically, using existing water bags to perform static pressure tests on glass can result in uneven force on the glass, affecting the accuracy of the test results. Furthermore, inaccurate water level control can easily lead to overly high or low overall water pressure, further affecting the accuracy of the test results. Utility Model Content

[0004] The purpose of the present utility model is to address the problem that the existing single-cavity water storage bag easily causes uneven force on the glass during the static pressure test of the glass, and the water level in the water storage bag is not accurately controlled, which easily leads to inaccurate test results. The present utility model designs a multi-cavity glass static pressure test device, which effectively solves the above-mentioned problem of inaccurate test results caused by uneven force and inaccurate water level control.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] The utility model designs a multi-cavity glass static pressure resistance test device, which includes:

[0007] A multi-chamber water storage bag has several isolated water storage chambers, and a pressure sensor is provided at the bottom of each water storage chamber; a water injection device is used to inject water into each water storage chamber; a test support frame is provided below the multi-chamber water storage bag and is used to place glass during static pressure resistance testing; an electronic water injection valve is used to control the amount of water injected into each water storage chamber; and a water source device is used to provide the required amount of water for injection.

[0008] Wherein, the pressure sensor is configured as a resistive film pressure sensor.

[0009] Furthermore, a multi-cavity glass static pressure resistance testing device: the number of the electronic water injection valves is set according to the number of the water storage chambers; several of the electronic water injection valves are connected to the water injection device through several water injection pipes, so as to inject water into each water storage chamber respectively, and several of the electronic water injection valves are connected to the water source device through the main water inlet pipe.

[0010] Furthermore, a multi-cavity glass static pressure resistance testing device is provided: the pressure sensor and the electronic water injection valve are connected to the terminal PLC controller, and the real-time pressure of each water storage cavity is monitored, thereby using each electronic water injection valve to adjust the water injection amount.

[0011] Furthermore, a multi-cavity glass static pressure resistance test device is provided with an anti-puncture layer at the bottom of each water storage cavity. Specifically, the anti-puncture layer can be made of TPU material.

[0012] Furthermore, a multi-cavity glass static pressure resistance testing device is provided: a rubber strip is provided on the contact surface of the test support frame with the glass.

[0013] Furthermore, a multi-cavity glass static pressure resistance testing device: the water injection device is arranged above the multi-cavity water storage bag.

[0014] Furthermore, a multi-cavity glass static pressure resistance testing device: the water injection device is also provided with a plurality of hooks, and the multi-cavity water storage bag is hung on the water injection device through the hooks.

[0015] Furthermore, a multi-cavity glass static pressure resistance testing device: the water injection device is also provided with a plurality of chains, and the water injection device is connected to the traveling vehicle through the chains.

[0016] Beneficial effects of the utility model:

[0017] (1) The multi-cavity glass static pressure resistance testing device designed in the present invention can avoid the problem of uneven force on the glass caused by the existing water storage bag during the glass testing process, which affects the accuracy of the test results. It can also avoid the problem of inaccurate water level control during the existing water storage bag testing process, which causes the overall water pressure to be too high or too low, affecting the accuracy of the test results.

[0018] (2) When conducting a static pressure test on glass, the existing single-cavity water storage bag needs to be placed on the glass and then filled with water. After the water is filled, the glass is affected by the gravity of the water and will undergo a certain degree of bending deformation, which causes the water to converge to the middle. Therefore, the water level in the middle is high and the water levels on both sides are low, resulting in poor force uniformity on the glass, affecting the accuracy of the test results. In addition, the existing single-cavity water storage bag controls the amount of water to be filled by the water level in the water bag, which has poor accuracy and will further affect the accuracy of the test results. Therefore, for the existing single-cavity water storage bag, the water level in the water bag is used to control the amount of water to be filled. In order to solve the problems existing in the process of static pressure resistance test of glass using multi-cavity water storage bags, the utility model designs a multi-cavity glass static pressure resistance test device, which makes the water pressure distribution not affected by the deformation of the glass, more evenly distributed and with high accuracy of the test results through the structural design of the multi-cavity water storage bag and the electronic control device (electronic water filling valve). The multi-cavity water storage bag designed by the utility model can adjust the water filling amount of each cavity through the linkage design of the pressure sensor and the electronic water filling valve when filling water, so that the force is even and the total pressure obtained by the summary is highly accurate.

[0026] Example 1

[0027] like Figure 3 As shown, in this embodiment 1, a multi-cavity glass static pressure resistance test device is designed, and the test device includes:

[0028] The multi-cavity water storage bag 1 has a plurality of mutually isolated water storage chambers 11. Each water storage chamber 11 is configured as a square chamber with a uniform shape. A resistive film pressure sensor and a TPU anti-puncture layer are provided at the bottom of each water storage chamber 11. The pressure sensor is connected to a terminal PLC controller. The material of the multi-cavity water storage bag 1 can be PVC.

[0029] A water injection device 2 is provided above the multi-cavity water storage bag 1 and is used to inject water into each water storage chamber 11. The water injection device 2 is also provided with a plurality of hooks 7, and the multi-cavity water storage bag 1 is hung below the water injection device 2 through the hooks 7. The water injection device 2 is also provided with a plurality of chains 8, and the water injection device 2 can be connected to the vehicle through the chains 8;

[0030] The test support frame 3 is provided below the multi-chamber water storage bag 1 and is used to place the glass 9 during the static pressure test and provide support for the glass 9. A rubber strip for protecting the glass is also provided on the contact surface of the test support frame 3 with the glass 9.

[0031] The electronic water injection valve 4 is used to control the amount of water injected into each water storage chamber 11.

[0033] like Figure 1 As shown, when conducting a glass static pressure resistance test with an existing single-cavity water storage bag, the water storage bag needs to be placed on the glass and then filled with water. After the water is filled, the glass is affected by the gravity of the water and will undergo a certain bending deformation, which causes the water to converge to the middle.

The bottom of each water storage chamber 11 has a pressure sensor (not shown in the figure), which is laminated between the inner wall of the water storage bag and the TPU anti-puncture material; the test support frame 3 can be composed of aluminum profiles, and the four sides of the support surface are padded with rubber strips (not shown in the figure); the electronic water injection valve 4 and the pressure sensor are connected to the terminal PLC controller, and the total pressure and uniformity are adjusted by real-time pressure and water injection volume; the water injection device 2 is connected to the driving vehicle (not shown in the figure) through multiple chains 8, and the multi-cavity water storage bag 1 is connected to the bottom of the aluminum profile frame of the water injection device 2 through multiple hooks 7.
