Description

Technical Field

[0001] This utility model belongs to the field of environmental testing technology for solar cell modules, specifically relating to a hailstone placement device for a hailstone launcher. Background Technology

[0002] Most solar cells are installed outdoors and are easily affected by hail. To ensure that solar cells can withstand hail impacts when operating outdoors, both the IEC 61215 standard "Design qualification and type approval of terrestrial crystalline silicon solar cell modules" and the GB / T 9535 standard "Design qualification and type approval of terrestrial crystalline silicon solar cell modules" include hail impact test indicators to meet the climatic environmental conditions that solar cells can withstand in the operating environment.

[0003] In actual production processes, hail launchers are needed to simulate the high-speed impact force of hail during its descent. A utility model patent with application number "202322239047.0" and patent title "A Hail Launching Device for a Hail Launcher" involves placing the hailstone to be tested on a hailstone loading device, and finally launching it under the pressure of an upper gas tank, thus simulating the process of hail falling. In the aforementioned utility model patent, the hailstone to be tested is initially placed on the loading device. If the diameter of the launching opening on the loading device is too large, the hailstone will fall directly off the device; if the diameter of the launching opening is too small, the hailstone will get stuck at the launching opening, preventing it from falling properly and affecting the hail impact test. Utility Model Content

[0004] This invention provides a hailstone placement tool for a hailstone launcher, which solves the defects of existing hailstone loading devices where the launching opening is too large, causing hailstones to fall directly, or the launching opening is too small, causing hailstones to get stuck, ultimately affecting the hailstone impact test.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a hail launcher for placing workpieces with hail, comprising:

[0006] A ball-loading box, which is detachably mounted on a launch pipe having an inlet and an outlet;

[0007] A ball trough, which passes through the ball-filling box and is connected to the outlet of the launch pipe;

[0008] A carrying assembly is arranged around the inner circumference of the ball groove for carrying hailstones placed inside the ball groove.

[0009] Optimally, the carrying assembly includes a ball-blocking device elastically disposed on the inner circumference of the ball groove, the ball-blocking device being used to carry hail placed in the ball groove.

[0010] Optimally, the support assembly further includes a spring groove formed on the inner circumferential surface of the ball groove, a limiting part inclinedly disposed inside the spring groove, and a spring disposed in the spring groove, wherein the ball block abuts between the limiting part and the spring.

[0011] Optimally, the support assembly further includes a threaded groove formed on the outer peripheral surface of the ball loading box and coaxially arranged with the spring groove, and a screw screwed into the threaded groove, the screw abutting against the side of the spring away from the ball stop.

[0012] Ideally, it also includes a clearance groove formed on the top of the ball box and an inner guide portion inclined inside the clearance groove.

[0013] Optimally, it also includes a sealing groove formed on the outer peripheral surface of the ball loading box and a sealing ring embedded in the sealing groove, the sealing ring abutting against the inner wall of the launch pipe inlet.

[0014] Ideally, it also includes an outer guide portion that is inclined at the bottom of the ball-loading box.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] This utility model of a hail launcher uses a hailstone placement workpiece. By setting a support component on the circumference of the ball groove, the loaded hailstone is supported. During actual spraying, the hailstone overcomes the elastic support that blocks the ball and is finally shot out from the hailstone launching pipe, thus simulating the process of hailstone falling. The structure is simple. When loading the ball, it can not only support the hailstone and prevent it from falling directly, but also avoid the falling path of the hailstone during spraying, preventing the hailstone from getting stuck in the launching port.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] like Figure 1-4 The diagram shows a hailstone placement mechanism for the hailstone launcher of this utility model. The hailstone loading structure includes a loading box 1, a clearance groove 2, an inner guide part 3, a ball groove 4, a sealing groove 5, a sealing ring 6, an outer guide part 7, a threaded groove 8, a spring groove 9, a limiting part 10, a ball stop 11, a spring 12, and a screw 13. The loading box 1 is installed on the hailstone launching pipe fixing component by insertion (specifically, the bottom of the hailstone launching pipe fixing component is fixed with the hailstone launching pipe, and the hailstone launching pipe fixing component and the hailstone launching pipe are internally connected. The hailstone launching pipe has a hailstone inlet and a hailstone outlet. The loading box 1 is installed on the hailstone launching pipe fixing component by insertion and is connected to the hailstone inlet of the hailstone launching pipe. For the structure and launching principle of the hailstone launcher, please refer to the following patent: the patent application number is "202322239047.0", and the patent name is "A hailstone launching device for a hailstone launcher").

[0024] The ball-filling box 1 is installed at the opening of the hail launching pipe fixing component by plugging it in. The outer diameter of the ball-filling box 1 is equal to the diameter of the opening of the hail launching pipe fixing component. During installation, it can not only play a sealing role, but also facilitate replacement. Different hail ball-filling boxes 1 of different sizes can be replaced according to different test environments.

[0025] like Figure 1 , 2 As shown, the ball-loading box 1 is cylindrical in shape (its shape is not limited to a cylindrical shape and can be adjusted according to the shape of the opening of the hail launching pipe fixing component). The top of the ball-loading box 1 is provided with a clearance groove 2, and the inner guide part 3 is inclinedly opened on the top of the clearance groove 2. The diameter of the inner guide part 3 gradually decreases from top to bottom. By setting the clearance groove 2, the gas storage tank above is avoided, ensuring that the gas storage tank can descend and make close contact with the ball-loading box 1.

[0026] The ball groove 4 runs vertically through the ball box 1 and is connected to the hail inlet of the hail launching pipe. In the actual simulation experiment, under the jet action of the gas pressure in the gas tank, the hail is launched along the ball groove 4 and the hail launching pipe to complete the simulation of the hail falling process.

[0027] The sealing groove 5 is opened on the outer circumference of the bottom of the ball-loading box 1, and the sealing ring 6 is fitted inside the sealing groove 5. In actual installation, the ball-loading box 1 is inserted into the opening of the hail launching pipe fixing component. By setting the sealing groove 5 and the sealing ring 6, the sealing performance between the ball-loading box 1 and the hail launching pipe fixing component is improved, and air leakage is avoided, which would affect the test results.

[0028] The outer guide part 7 is inclinedly opened at the bottom of the ball box 1. By setting the outer guide part 7, the ball box 1 is guided during installation, which facilitates its installation.

[0029] like Figure 3 As shown, the threaded groove 8 is arranged horizontally around the outer circumference of the ball-loading box 1, and the spring groove 9 is arranged around the inner circumference of the ball groove 4 and communicates with the threaded groove 8. The spring groove 9 and the threaded groove 8 are coaxially arranged. The limiting part 10 is inclinedly arranged on the side of the spring groove 9 away from the threaded groove 8, and the diameter of the limiting part 10 on the side closer to the spring groove 9 is larger than the diameter of the limiting part 10 on the side away from the spring groove 9. When the blocking ball 11 is ejected, it limits the ejected blocking ball 11 to prevent the blocking ball 11 from being ejected from the spring groove 9 and falling into the hail launching pipe below.

[0030] like Figure 4 As shown, the retaining ball 11 fills the spring groove 9 and abuts against the limiting part 10. The spring 12 is installed in the spring groove 9 and abuts against the retaining ball 11. The screw 13 is screwed into the threaded groove 8 and abuts against the spring 12 (the inner circumferential surface of the threaded groove 8 is provided with internal threads, and the outer circumferential surface of the screw 13 is provided with external threads that mate with the internal threads). By screwing the screw 13, the screw 13 will gradually move inward, thereby pressing the spring 12 against it. The pressed spring 12 will press inward against the retaining ball 11. Finally, the multiple retaining balls 11 arranged in a circle support the hail placed on top of the ball groove 4.

[0031] In the actual simulation experiment, under the spraying action of the gas pressure in the gas tank, the hail moves downward along the ball groove 4. Since the other side of the baffle ball 11 is pressed by the spring 12, it is elastically compressed rather than rigidly compressed. Therefore, the falling hail will push against the baffle ball 11 and move outward, and finally be shot out from the hail launching pipe, thus completing the simulation of the hail falling process.

[0032] By adjusting the screw 13 to a certain depth, the preload of the spring 12 can be changed, thereby improving the adaptability of the ball-loading structure.

[0033] This utility model's hail launcher uses a support component on the circumference of the ball groove 4 to support the loaded hail. During actual spraying, the hail overcomes the elastic support of the ball 11 and is finally ejected from the hail launching pipe, thus simulating the process of hail falling. The structure is simple, providing support for the hail during loading to prevent direct fall, and avoiding the hail's descent path during spraying to prevent it from getting stuck at the launching port. The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made according to the spirit and essence of this utility model should be included within the scope of protection of this utility model.
