The invention discloses a solar water heater support stability detection device, the device comprises a vertical rack, a simulation water tank and a driving system, a pedestal is arranged on one side of the bottom end of the vertical rack; the simulation water tank is arranged above the pedestal in a suspended manner and is driven by the driving system to move, a fixing part fixedly connected with the top end of a solar water heater support is arranged on the simulation water tank, a force sensor used for detecting force magnitude suffered by the solar water heater support is arranged on the simulation water tank, the force sensor comprises a pressure sensor for detecting vertical pressure suffered by the solar water heater support in X-axis direction, and a shearing force sensor for detecting lateral shearing force suffered by the solar water heater support in Y-axis direction and Z-axis direction; and one of the Y-axis direction and the Z-axis direction is the same with the length direction of the simulation water tank. According to the invention, the stability of the solar water heater support can be conveniently, accurately and effectively detected, and the device has good using effect.

Description

technical field [0001] The invention relates to a device for detecting the stability of a solar water heater bracket, and belongs to the technical field of solar water heater bracket production equipment. Background technique [0002] With the development of science and technology and the improvement of people's awareness of environmental protection, more and more users start to use solar water heaters. Solar water heater is a device that converts solar energy into heat energy to achieve the purpose of heating water, that is, under the sunlight, the vacuum tube absorbs solar energy and the temperature rises, the water in the water storage tank is continuously heated through the vacuum tube, and the heated water continues to rise along the vacuum tube and enter into the water storage tank, so that the water in the water storage tank is continuously heated by reciprocating circulation. The vacuum tube and the water storage tank of the solar water heater are fixed by the solar...

AI Technical Summary

Problems solved by technology

The vacuum tube and the water storage tank of the solar water heater are fixed by the solar water heater support (the water storage tank is fixed on the top of the solar water heater support, and the vacuum tubes are arranged at intervals along the width direction of the solar water heater support). It is installed at the same height and in the open air, so it is greatly affected by severe weather such as heavy rain, storm, thunder, lightning, and hail. If the factory solar water heater bracket is not stable, it will not only affect the service life of the solar water heater, but also pose a safety hazard. Therefore, in the solar water heater bracket It is very necessary for the manufacturer to conduct a stability test on the product before leaving the factory (such as stiffness, strength and stability test)

[0003] The traditional method of testing the stability of the solar water heater bracket is: hang a large stone on the solar water heater bracket and let it stand for several hours, and then observe whether the bracket has obvious deformation, so as to judge the stability of the solar water heater bracket. This detection method is time-consuming. work, and because the support is only subjected to vertical downward pressure during the test, it can only judge the vertical downward compressive capacity of the support, but cannot judge the lateral compressive capacity of the support well, which leads to the test result Not accurate enough

[0004] In this regard, the existing equipment on the market that can detect the stability of the solar water heater support includes a vertical frame and a simulated water tank. The driving device, the action of the driving device is controlled by the control system. When testing the stability, the driving device drives the simulated water tank to move downwards and exerts downward pressure on the bracket, so as to judge the compression resistance of the bracket. The operation of the equipment saves time and effort, but it still cannot detect the lateral compressive capacity of the support, so the test results are still inaccurate
