[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] In one embodiment, Figure 1-Figure 3 As shown, an adjustment-free monitoring prism device includes a monitoring prism 102; in this embodiment, the bottom end of the monitoring prism 102 is connected to a fixing column 103, the bottom end of the fixing column 103 is connected to a counterweight 104, the middle of the fixing column 103 is connected to a first rotating shaft 201, the first rotating shaft 201 is rotatably connected to a first fixing ring 204, the outer side of the first fixing ring 204 is symmetrically connected to two second rotating shafts 202, the second rotating shaft 202 is rotatably connected to a second fixing ring 205, the The outer side surface of the second fixed ring 205 is symmetrically connected to two third rotating shafts 203, and the third rotating shaft 203 is rotatably connected to the monitoring prism housing 101. The counterweight block 104 lowers the center of gravity of the monitoring prism 102. In conjunction with the first rotating shaft 201, the second rotating shaft 202, the third rotating shaft 203, the first fixed ring 204, the second fixed ring 205 and the monitoring prism housing 101, the upper surface of the fixed column 103 always remains horizontal, and the lower end of the monitoring prism 102 is connected to the always horizontal upper surface of the fixed column 103.

[0024] In one embodiment, Figure 2 As shown, the connection point between the fixing column 103 and the first rotating shaft 201 is located in the center of the first rotating shaft 201 .

[0025] In one embodiment, Figure 2 and Figure 3 As shown, the axes of the first fixing ring 204, the second fixing ring 205 and the fixing column 103 are collinear.

[0026] In one embodiment, Figure 3 As shown, the axis of the first rotating shaft 201 and the axis of the second rotating shaft 202 form an angle of 60 degrees.

[0027] In one embodiment, Figure 3 As shown, the axis of the second rotating shaft 202 and the axis of the third rotating shaft 203 form an angle of 60 degrees.
