Among them, the observation plate 3 can not only block splashing foreign objects, but also provide a safe and reliable observation path for the test equipment or staff behind the observation plate 3.

[0026] Specifically, the support plate 1 and the support frame 2 are connected by the connection assembly 4, and the top of the support frame 2 is detachably connected to the support plate 1, so that a triangular structure is formed among the support plate 1, the support frame 2, and the connection assembly 4, providing the stability of protection.

[0027] Among them, refer to Figure 2 , the connection assembly 4 is preferably horizontally arranged. One end of the connection assembly 4 is detachably connected to the support plate 1, and the other end of the connection assembly 4 is detachably connected to the support frame 2. The connection assembly 4 can be selectively detachably connected to the support plate 1 and the support frame 2 respectively through hexagon head bolts; it is convenient to disassemble and carry, facilitates transportation, and is also convenient to install during use, improving the disassembly and assembly efficiency and portability, and meeting the actual protection requirements.

[0028] Further explanation: The connecting component 4 can be selected as two. Each connecting component 4 includes one, two or more horizontal connecting members 6. The two connecting components 4 are arranged on the left and right sides of the support plate 1. When the number of the horizontal connecting members 6 is two, the two horizontal connecting members 6 are arranged vertically, and preferably one of the horizontal connecting members 6 is located between the bottom of the support plate 1 and the bottom of the support frame 2. In this embodiment, an example is given where the connecting component 4 includes three horizontal connecting members 6, and the three horizontal connecting members 6 are respectively an upper horizontal connecting member b, a middle horizontal connecting member c and a lower horizontal connecting member d.

[0029] The upper horizontal connecting member b, the middle horizontal connecting member c and the lower horizontal connecting member d in the same group are arranged at intervals in the vertical direction, preferably at equal intervals. The lower horizontal connecting member d is located between the bottom of the support plate 1 and the bottom of the support frame 2, and the upper horizontal connecting member b is located on one side of the observation plate 3. The two groups of upper horizontal connecting members b, middle horizontal connecting members c and lower horizontal connecting members d are all at the same height, which is used to provide more stable and reliable support performance for the support plate 1 and improve the overall protection effect.

[0030] The upper horizontal connecting member b, the middle horizontal connecting member c and the lower horizontal connecting member d can all be selected as angle steels.

[0031] Preferably, the included angle between the support plate 1 and the connecting component 4 is an acute angle, preferably 85° - 65°, which is used to improve the stability of the support plate 1. Further preferably, the included angle between the support plate 1 and the connecting component 4 is 75°. At the same time, the included angle between the support frame 2 and the connecting component 4 is an acute angle, preferably 85° - 65°, which improves the support stability of the support plate 1. Further preferably, the included angle between the support frame 2 and the connecting component 4 is 85°. In order to improve the installation accuracy of the connecting component 4, the included angles between the two sides of the connecting component 4 and the bottom are 75° and 85° respectively, which further improves the installation efficiency of the connecting component 4 and the reliability of the protection of the support plate 1.

[0032] By arranging the support plate 1 obliquely, on the one hand, it can reduce the impact force of foreign objects splashing in the horizontal direction on the support plate 1, avoid the support plate 1 from tipping backward, and improve the protection effect. At the same time, it can also avoid the support plate 1 from tipping forward, further improve the protection effect, and meet the actual protection requirements.

[0033] Further explanation: An observation window 5 is opened on the support plate 1, and the observation plate 3 covers the outside of the observation window 5. The observation plate 3 is detachably connected to the support plate 1, which is convenient for replacing and disassembling the observation plate 3, reduces the use difficulty, and improves the portability.

The high-speed camera is placed on the back of the support plate 1 through a tripod. The size of the support plate 1 can be selected as 1200 mm × 1900 mm. The support plate 1 provides a sufficient protection range for the high-speed camera. At the same time, the high-speed camera can adjust the height by using the tripod, and the observation board 3 provides a sufficiently open observation field of view range for the high-speed camera.

[0036] The observation board 3 can be detachably connected to the support plate 1 by means of bonding, magnetic attraction, adsorption or clamping, etc. Preferably, the observation board 3 is detachably connected to the support plate 1 through the limiting member a, which improves the connection stability and reliability of the observation board 3.

One side of the limiting member a can be connected to the support plate 1 through an inner hexagon socket head cap screw, and the other side of the limiting member a is used to limit the observation board 3.

[0038] The number of the limiting members a is multiple, and the multiple limiting members a are arranged at intervals along the circumferential side of the observation window 5, and the limiting grooves e all face the observation window 5. Taking the number of the limiting members a being four as an example for illustration, one limiting member a is arranged in the middle of each of the left and right sides of the observation window 5, and two limiting members a are symmetrically arranged at the bottom of the observation window 5. During actual use, the observation board 3 is clamped in the limiting grooves e of the four limiting members a, providing a stable and reliable connection for the observation board 3, with simple operation and convenient disassembly and assembly.

Preferably, the side plates of the lower support connecting member 9 are detachably connected to the rear support connecting members 8 by hexagon head bolts; the top of the rear support connecting member 8 is hinged to the top of the support plate 1, which is convenient for disassembling and storing the support frame 2; the rear support connecting member 8 is connected to the corresponding side of the support plate 1 through the connecting component 4.

[0040] Preferably, front support connecting members 7 are arranged on both the left and right sides of the support plate 1. The front support connecting members 7 and the rear support connecting members 8 can both be selected as angle steels. At this time, the top of the rear support connecting member 8 is hinged to the top of the support plate 1 through the corresponding front support connecting members 7, and the connecting component 4 is connected to the support plate 1 through the front support connecting members 7.
