[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An ice vibration fatigue testing device for ice-concrete collision experiments includes a fixing component 1, an adjusting component 2, a concrete body 3, and a base 4. The fixing component 1 and the adjusting component 2 are both located on the top of the base 4. The concrete body 3 is located inside the fixing component 1. The fixing component 1 includes a rotating column 101, a limiting block 102, a stop plate 103, a connecting frame 104, and a placement box 105. The rotating column 101 is threaded to the rear side of the connecting frame 104. The limiting block 102 is fixedly connected to the front side of the rotating column 101. The stop plate 103 is rotatably connected to the front side of the limiting block 102. The connecting frame 104 is fixedly connected to the rear side of the placement box 105. The placement box 105 is fixedly connected to the top of the base 4.

[0026] In this embodiment: By setting the fixing component 1, the fixing component 1 can achieve the effect of fixing the concrete body 3, thereby preventing the concrete body 3 from moving during the experiment and affecting the experimental data. By setting the adjusting component 2, the adjusting component 2 can achieve the effect of clamping and fixing ice blocks of different sizes. Thus, when used with the fixing component 1, the concrete body 3 can be subjected to a collision experiment. By setting the rotating column 101, the rotating column 101 can be used with the connecting frame 104 to achieve the effect of adjusting the backing plate 103.

A first motor 202 is fixedly connected to the front side of the adjustment rod 201, and limit rods 203 are fixedly connected to both sides inside the base 4.

[0028] Specifically, such as Figure 4 As shown, the surface of the adjusting rod 201 is threadedly connected to the adjusting seat 204, the top of the adjusting seat 204 is fixedly connected to the connecting seat 205, the top of the connecting seat 205 is fixedly connected to the adjusting box 206, the inside of the adjusting box 206 is rotatably connected to the rotating rod 207, and the left side of the rotating rod 207 is fixedly connected to the second motor 208.

[0029] Specifically, such as Figure 4 As shown, an adjusting plate 209 is threadedly connected to the surface of the rotating rod 207, a clamping plate 210 is fixedly connected to the top of the adjusting plate 209, a phase change heat insulation pad 211 is fixedly connected to the inner side of the clamping plate 210, and a fixing plate 212 is fixedly connected to the top of the adjusting box 206.

[0030] In this embodiment: The adjusting rod 201 allows for a threaded connection to the adjusting seat 204, enabling back-and-forth adjustment of the adjusting seat 204. The first motor 202 drives the adjusting rod 201 to rotate. The limiting rod 203 provides a limiting sliding connection to the connecting seat 205. The adjusting seat 204 connects to the connecting seat 205, which in turn connects to the adjusting box 206. The adjusting box 206 allows for the adjustment of the rotating rod 207. The rotating connection is achieved through the setting of the rotating rod 207, which is an existing bidirectional threaded rod, thereby achieving the effect of opposing adjustment of the adjusting plate 209. The second motor 208 can drive the rotating rod 207 to rotate. The adjusting plate 209 can connect to the clamping plate 210. The clamping plate 210, in conjunction with the phase change insulation pad 211, can clamp and fix the ice block. The fixing plate 212 can position the ice block. The phase change insulation pad 211 is made of phase change insulation material such as paraffin PCM, which can help slow down the melting of the ice block.

[0031] Specifically, such as Figure 5 As shown, the base 4 has connecting holes 5 on both sides inside, and the inside of the connecting holes 5 is rotatably connected to the two sides of the limiting rod 203.

[0032] Specifically, such as Figure 5 As shown, a rotating hole 6 is provided on the front side of the base 4, and the interior of the rotating hole 6 is rotatably connected to the surface of the adjusting rod 201.

[0033] In this embodiment: the connection hole 5 can achieve the effect of rotating the limiting rod 203, and the rotation hole 6 can achieve the effect of rotating the adjusting rod 201.

[0034] Specifically, such as Figure 5 As shown, a threaded hole 7 is provided on the rear side of the placement box 105, and the interior of the threaded hole 7 is threadedly connected to the surface of the rotating column 101.

[0036] In this embodiment: by setting the threaded hole 7, the threaded hole 7 can achieve the effect of threaded connection to the rotating column 101, and by setting the limiting hole 8, the limiting hole 8 can achieve the effect of limiting rotation connection to the limiting block 102.

[0037] Working principle: First, the concrete body 3 is placed inside the placement box 105. Then, the rotating column 101 is twisted, causing the rotating column 101 to work with the connecting frame 104 to adjust the backing plate 103 back and forth. This allows the backing plate 103 to press and fix the concrete body 3. Then, the experimental ice block can be placed on top of the adjustment box 206. Then, the second motor 208 is turned on, causing the second motor 208 to drive the rotating rod 207 to rotate. This causes the rotating rod 207 to drive the adjustment plate 209 to adjust in opposite directions, thus allowing the adjustment plate 209 to adjust in opposite directions. 09 drives the clamping plate 210 and the phase change insulation pad 211 to clamp and fix the ice block. Then the first motor 202 can be turned on, so that the first motor 202 drives the adjusting seat 204 to adjust back and forth. In turn, the adjusting seat 204 drives the connecting seat 205 and the adjusting box 206 to adjust back and forth, so that the ice block collides with the concrete body 3. The collision data can be recorded. The collision force can be controlled by adjusting the speed of the first motor 202 remotely. This device is small and convenient, making it easy for universities or small and medium-sized laboratories to use.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
