Detection device for stability of solar water heater support

Abstract

The invention provides a detection device for stability of a solar water heater support, and belongs to the technical field of solar detection. The detection device comprises a detection rack, a simulation water tank and a base. The detection rack is installed on the upper end of the base. A detection platform where the solar water heater support is placed is arranged on the base. A fixed rack extending to one side of the solar water heater is arranged on the upper end of the detection rack. A pressure imposing structure 1 is arranged on the fixed rack. The simulation water tank is fixed on the pressure imposing structure 1. A pressure imposing structure 2 is arranged in the middle part, close to one side of the solar water heater support, of the detection rack. Pressure imposing structures 3 are arranged on adjacent two sides of the pressure imposing structure 2 on the detection rack. Force sensors are arranged on the pressure imposing structure 1, the pressure imposing structure 2 and the pressure imposing structures 3. Stopping plates corresponding to two sides of the pressure imposing structure 2 are arranged on the detection platform. According to the invention, a point place where the solar water heater support bears the pressure is simulated and stability detection of the solar water heater support is improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy detection, and relates to a detection device for the stability of a solar water heater support. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. Since the solar water heater is installed on a high place such as the roof and is installed in the open air, it is greatly affected by severe weather such as heavy ra...

AI Technical Summary

Problems solved by technology

Since the solar water heater is installed on a high place such as the roof and is installed in the open air, it is greatly affected by severe weather such as heavy rain, storm, thunder, lightning and hail. Hidden dangers, so it is necessary for the manufacturer to conduct a stability test on the product (such as stiffness, strength and stability test) before the solar water heater bracket leaves the factory

[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 compressive capacity of the support in other directions, so the detection is relatively simple, not comprehensive enough, and the accuracy is poor
