Abstract

The utility model discloses a hail impact testing machine which comprises a machine frame, an ice ball jet device and an air compressing device. The machine frame comprises a lower table board and an upper table board. The ice ball jet device is disposed on the upper table board in a sliding mode through a sliding rail assembly and comprises a frame body. An upper guide tube and a lower guide tube are vertically disposed on the frame body along the same axial direction, an outlet end of the upper guide tube is aligned to an inlet end of the lower guide tube and a gap is formed between the outlet end of the upper guide tube and the inlet end of the lower guide tube, and the outlet end of the lower guide tube is aligned to the lower table board. A group of laser speed detecting devices is disposed on the frame body which is corresponding to the gap and a damping ring is disposed on the inner wall of the upper guide tube. The outlet end of the air compressing device is connected with the upper guide tube. In the process of operation, firstly, the hail impact testing machine utilizes the sliding rail assembly to move the ice ball jet device to a specified position, an ice ball is placed into the upper guide tube, and the damping ring is used to prevent the ice ball from dropping; secondly, compressed air is provided through the air compressing device to impact the ice ball and enables the ice ball to drop into the lower guide tube; and then the ice ball impacts an object to be tested and a relative testing is completed.

Description

The hail impact testing machine

Technical field

The utility model relates to a kind of hail impact testing machine, refer to a kind of experimental provision that the emulation hail impacts assemblies such as solar panels, cell panel that is used for especially.

Background technology

Because solar panels or relevant device all are to be positioned over outdoor that periods of direct sunlight and nothing hide, receive the variable effect of weather easily and cause the aging of solar facilities and damage.Through facts have proved, in various natural causes, because hail is to fall from the high-altitude, thus be easy to damaged at outdoor solar panels or equipment bump, so the impact of hail is the main cause that causes solar panels to damage.

The utility model content

The technical matters that the utility model will solve is, provides a kind of device to fall the bump Related product by the emulation hail, carries out dependence test, thereby obtains the further exploitation of Related product of data.

Unresolved above-mentioned technical matters the utility model discloses a kind of hail impact testing machine, comprising: a frame, said frame comprise that one is used to place the following table of thing to be detected, and one be positioned at said following table top upper table surface; One ice hockey jetting system; Be set up in the upper table surface of said frame slidably through slide track component; Said ice hockey jetting system comprises a support body; Same axis direction has vertically set up on one guide pipe and guide pipe once in said support body upper edge, and the said endpiece of going up guide pipe is over against the inlet end of said guide pipe down and form a gap, and the endpiece of said guide pipe down is over against said following table; The corresponding said interstitial site of said support body is provided with one group of laser velocimeter device, and the said guide pipe inwall of going up is provided with a damped ring; One blowing plant, said compressed-air actuated endpiece connect the said guide pipe of going up.

When the testing machine of the utility model uses; At first utilize slide track component that the ice hockey jetting system is moved to assigned address, the ice hockey that makes is put into guide pipe, and prevent its whereabouts through damped ring; Through blowing plant pressurized air is provided then; Impact said ice hockey and fall to getting into guide pipe down, and then clash into thing to be detected, thereby accomplish coherent detection.

Fig. 2 is the enlarged diagram of ice hockey jetting system in the utility model hail impact testing machine.

Embodiment

Embodiment to the utility model elaborates below in conjunction with accompanying drawing, and present embodiment is a prerequisite with the utility model technical scheme, provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.

Consult shown in Figure 1ly, the hail impact testing machine 1 of the utility model mainly is by frame 10, and ice hockey jetting system 20 and blowing plant 30 are formed, wherein:

Frame 10 is a framed structure, and it comprises a following table 11 and a upper table surface 12, on following table 11, is placed with band and detects thing 40, and this thing 40 to be detected can be solar panels or relevant device, but also is not limited thereto;

Ice hockey jetting system 20 is set up on the upper table surface 12 of frame 10 slidably through slide track component 50; This slide track component 50 comprises one first slide rail 51 and one second slide rail 52; First slide rail 51 is set up on the said upper table surface 12; Second slide rail 52 is set up on first slide rail 51 through a slide rail contiguous block 53, ice hockey jetting system 20 then further travelling carriage be located on second slide rail 52; Further cooperate shown in Figure 2; Ice hockey jetting system 20 comprises a support body 21; The same axis direction in support body 21 upper edges has vertically set up on one guide pipe 22 and guide pipe 23 once, and the inlet end 221 of last guide pipe 22 is provided with a slide 222; The endpiece 223 of last guide pipe 22 is over against the inlet end 231 of following guide pipe 23; And between the inlet end 231 of the endpiece 223 of last guide pipe 22 and following guide pipe 23, also be formed with a gap 24,232 of the endpiece of following guide pipe 23 are further over against following table 11, and the position in corresponding gap 24 also is provided with one group of laser velocimeter device 70 on support body 21; Further, the inwall at last guide pipe 22 is provided with a damped ring 25;

Blowing plant 30 has comprised a gas-holder 31, and this gas-holder 31 connects through pipeline 32 goes up guide pipe 22, and on this pipeline 32, also further is provided with a solenoid valve 33.
