The monitoring body 1 is arranged on the support rod 2, and the monitoring body 1 is easily installed and fixed by the support rod 2. The mounting vertical pole 3 is arranged at the bottom of the support rod 2. The mounting vertical pole 3 and the support rod 2 are connected to the mounting seat 4 through the connecting component. The mounting seat 4 is arranged on the outside of the mounting vertical pole 3. The mounting vertical pole 3 is protected by the mounting seat 4, so that the monitoring body 1 can detect the water surface. The fixing seat 5 is fixedly installed on the outside of the mounting seat 4. The fixing seat 5 is provided with an installation limiting component. The installation limiting component is used to improve the stability of the installation vertical pole 3 and the support rod 2 during installation. In order to prevent the monitoring body 1 from easily moving during installation The situation of movement causes the support rod 2 and the installation upright pole 3 to tip over. The installation limiting assembly includes a limiting block 6, a telescopic plate 7, a connecting mechanism and a pushing mechanism. The limiting block 6 is arranged on the top of the fixed seat 5, and a telescopic plate 7 is arranged on one side of the limiting block 6. The limiting block 6 and the telescopic plate 7 are connected by a connecting mechanism. The pushing mechanism is arranged in the fixed seat 5, and is used to push the telescopic plate 7 to deflect. By moving the limiting block 6 and under the action of the connecting mechanism, the pushing mechanism pushes the telescopic plate 7 to deflect and stretch, so that the telescopic plate 7 supports and limits the limiting block 6 on both sides of the fixed seat 5. The limiting groove 8 is opened on the outside of the support rod 2, and the limiting block 6 is plugged into the limiting groove 8, so that the support rod 2 and the installation upright pole 3 remain stable during installation, which is convenient for workers to operate.

[0018] In order to limit the connection between the support rod 2 and the installation vertical rod 3 and improve the installation efficiency of the workers, the connecting assembly includes a first flange 15, a second flange 16, a limiting rod 17, a fixing rod 19 and a limiting mechanism. The first flange 15 is fixedly connected to the bottom of the support rod 2, the second flange 16 is fixedly connected to the top of the installation vertical rod 3, and the second flange 16 is located at the top end inside the mounting seat 4. Screw holes are provided on the first flange 15 and the second flange 16. The limiting rod 17 is fixedly connected to the two ends of the bottom of the first flange 15, and the fixing rod 19 is fixedly connected to the two ends of the top of the fixing seat 5. A plug-in slot is provided on the top of the fixing rod 19. The limiting rod 17 is plugged into the plug-in slot, so that the first flange 15 and the second flange 16 can be fitted and limited, and the screw holes are aligned so that the bolts can be screwed into the screw holes. A limiting mechanism is provided inside the limiting rod 17 and the fixing rod 19 for limiting the position of the first flange 15 and the second flange 16, so as to improve the stability of the connection between the first flange 15 and the second flange 16.

[0019] In the initial state, the limiting blocks 6 on the left and right sides of the fixing seat 5 are located outside the fixing seat 5 and away from the support rod 2, exposing the mounting pole 3 and the second flange 16. When the mounting pole 3 and the support rod 2 are installed, align the two limiting rods 17 at the bottom of the first flange 15 with the plug-in slot of the fixing rod 19, move the limiting rod 17 downward, and insert the limiting rod 17 into the inside of the plug-in slot, so that the first flange 15 fits one side of the second flange 16, align the screw holes, and at the same time, the limiting rod 17 squeezes the limiting mechanism, so that the limiting mechanism moves and is limited to the top of the mounting seat, further improving the stability of the connection and limitation between the first flange 15 and the second flange 16.

[0020] Then move the limiting blocks 6 on the left and right sides of the fixing seat 5 so that the limiting blocks 6 move to the side of the support rod 2 close to the limiting groove 8, move the limiting blocks 6 upward, drive the telescopic plate 7 to extend through the connecting mechanism, and at the same time, deflect the telescopic plate 7 under the action of the pushing mechanism. When the limiting blocks 6 are plugged into the limiting grooves 8 on both sides of the support rod 2, the support rod 2 is limited to the top of the mounting seat 4, and the limiting blocks 6 are supported and limited by the telescopic plates 7, and the stability of the connection between the support rod 2 and the mounting upright 3 is improved on both sides of the fixing seat 5. At this time, screw the bolts into the screw holes so that the support rod 2 is fixed to the mounting seat 4. The monitoring body 1 is fixed on the mounting pole 3. When the telescopic plates 7 and the limiting blocks 6 on the left and right sides of the fixing seat 5 are damaged and loosened after long-term use, the limiting blocks 6 on the front and rear sides of the fixing seat 5 are moved, and under the action of the telescopic plates 7, the connecting mechanism and the pushing mechanism, the connection between the support rod 2 and the mounting pole 3 is continued to be limited, which is convenient for switching and convenient for workers to operate, and prevents the monitoring body 1 from moving easily during installation, causing the support rod 2 and the mounting pole 3 to fall over, causing the monitoring body 1 to fall and be damaged, thereby further improving the service life of the monitoring body 1.

[0021] like Figures 2 to 6 As shown, in order to enable the limiting block 6 to limit the support rod 2, improve the stability of the connection between the installation vertical rod 3 and the support rod 2, and prevent the installation vertical rod 3 from moving when connected to the support rod 2, the connecting mechanism includes a first connecting block 9, a telescopic rod 10, a connecting rod 11 and a connecting plate 12. The first connecting block 9 is fixedly connected to one side of the limiting block 6, and the telescopic rod 10 is fixedly connected to the side of the first connecting block 9 away from the limiting block 6. The connecting rod 11 is rotatably connected to the bottom end of the telescopic rod 10, and the bottom end of the connecting rod 11 is connected to the pushing mechanism. The connecting plate 12 is fixedly connected to one end of the connecting rod 11, and one end of the connecting plate 12 is hinged to the top of the telescopic plate 7. By rotating the telescopic rod 10, the first connecting block 9 and the limiting block 6 are driven away from the support rod 2, so that the limiting block 6 is no longer located at the top of the first flange 15, and will not block the installation and disassembly of the first flange 15 and the second flange 16. The first connecting block 9 The shape of is arc-shaped, and it is convenient that when the limiting block 6 is plugged into the limiting groove 8, the arc-shaped side of the first connecting block 9 is in contact with the outer side of the support rod 2, thereby improving the stability of the limiting block 6. The telescopic rod 10, the first connecting block 9 and the connecting plate 12 are all located at the top of the fixing seat 5, and are distributed in a circular array with the center of the fixing seat 5. It is convenient to switch the limiting blocks 6 and telescopic plates 7 on the left and right sides of the fixing seat 5 and the limiting blocks 6 and telescopic plates 7 on the front and back sides of the fixing seat 5, saving replacement time. When the limiting blocks 6 and telescopic plates 7 on the left and right sides of the fixing seat 5 are damaged, the limiting blocks 6 and telescopic plates 7 on the front and back sides of the fixing seat 5 make the installation of the vertical rod 3 and the support rod 2 still remain stable. The outer side of the fixing seat 5 and the bottom end of the mounting seat 4 are provided with an installation groove, and the telescopic plate 7 is located inside the installation groove. The telescopic plate 7 is stored and protected by the installation groove to prevent the telescopic plate 7 from being damaged when not in use, affecting use.

[0022] When the telescopic rod 10 is moved and retracted, the first connecting block 9 and the limiting block 6 are moved and separated from the limiting groove 8. The telescopic rod 10 on the left and right sides of the rotating fixed seat 5 drives the first connecting block 9 and the limiting block 6 to rotate, so that the first connecting block 9 and the limiting block 6 are rotated to the fixed seat 5 twice, and then the first flange 15 and the support rod 2 and the second flange 16 are limited by the limiting rod 17 and the plug-in slot, and then the telescopic rod 10 and the first connecting block 9 and the limiting block 6 are rotated to the original position, and the limiting block 6 corresponds to one side of the limiting groove 8 of the support rod 2. Then the limiting block 6 is moved to drive the connecting rod 11 and the connecting plate 12 to move. When the limiting block 6 is plugged into the limiting groove 8, one side of the first connecting block 9 is fitted with the outer side of the support rod 2, and at the same time, the telescopic plate 7 is driven to move. The movement of the connecting rod 11 causes the pushing mechanism to push the telescopic plate 7 to deflect, and then the limiting block 6 is performed, so that the installation vertical rod 3 and the support rod 2 are limited.

[0023] like Figures 3 to 8When the lever 13 is unlocked, the lever 13 is unlocked and the spring 13 is in a locked state, so that the lever 13 is unlocked and the spring 13 is in a locked state.

[0024] When the limiting block 6 drives the connecting rod 11 to move upward, the connecting rod 11 drives the connecting plate 12 and the telescopic plate 7 to move upward, so that the telescopic plate 7 is extended. At the same time, the connecting rod 11 drives the inserting block 13 to move upward along the moving groove, so that the pushing plate 14 is no longer limited. In this embodiment, the first elastic member can be a compression spring, which pushes the pushing plate 14 to move along the movable groove toward the outside of the mounting seat 4 through the action of the first elastic member, thereby deflecting the telescopic plate 7, limiting the limiting block 6, and improving the stability of the limiting block 6 on the support rod 2. When the support rod 2 is disassembled, the push The pushing plate 14 moves to the inside of the movable groove to squeeze the first elastic member, and deflect the telescopic plate 7 to the inside of the installation groove, and move the limiting block 6 in the direction away from the support rod 2, so that the first connecting block 9 drives the telescopic rod 10 to retract, and at the same time separates the limiting block 6 from the limiting groove 8 and no longer restricts the support rod 2, and then moves the limiting block 6 downward, so that the telescopic plate 7 retracts, driving the connecting rod 11 and the insert block 13 to move downward, and the insert block 13 is plugged into the slot at the top of the pushing plate 14, so that the pushing plate 14 is confined inside the movable groove, and the telescopic plate 7 is stored inside the installation groove for protection.

[0025] like Figure 4 、 Figure 6 、 Figure 7As shown, in order to improve the stability of the connection between the first flange 15 and the second flange 16, so that the installation of the mounting rod 3 and the support rod 2 is stable, the limiting mechanism includes a moving rod 20, a moving block 21, a second elastic member 22 and a limiting rod 23. The moving rod 20 is fixedly connected to the bottom of the limiting rod 17, and the moving block 21 is movably connected to the inside of the fixed rod 19. One end of the third elastic member 25 is fixedly connected to the moving block 21, and one end of the third elastic member 25 is fixedly installed to the inner wall of the fixed rod 19. The limiting rod 23 is fixedly connected to one side of the moving block 21. Limiting grooves 18 are provided on both sides of the top of the mounting seat 4. The limiting rod 23 passes through the fixed rod 19 and is plugged into the limiting groove 18 at the top of the mounting seat 4, which is used to fix the first flange 15 on the top of the second flange 16. The bottom end of the moving rod 20 is a circular convex, one side of the moving block 21 is an inclined surface, and the other side is arc-shaped. The circular convex is located at the bottom end of the inclined surface of the moving block 21, which is used to squeeze the moving block 21 to drive the limiting rod 23 to move and limit it with the mounting seat 4.

[0026] When the moving rod 20 is inserted into the fixed rod 19, the first flange 15 and the second flange 16 fit together, and at the same time, the round protrusion at the bottom end of the moving rod 20 moves along the inclined surface of the moving block 21, squeezing the moving block 21, so that the third elastic member 25 is stretched, and the moving block 21 drives the limiting rod 23 to engage with the limiting groove 18, further improving the stability of the connection between the first flange 15 and the second flange 16. In this embodiment, the third elastic member 25 can be a compression spring. When the first flange 15 and the second flange 16 are disassembled, the moving rod 20 is no longer located inside the fixed rod 19 to squeeze the moving block 21. Through the action of the third elastic member 25, the moving block 21 drives the limiting rod 23 to move to its original position, and no longer limits the first flange 15, the second flange 16 and the mounting pole 3.

[0027] like Figures 9 and 10 As shown, in order to support and fix the telescopic plate 7, improve the stability of the telescopic plate 7 support, prevent the telescopic plate 7 from being moved by collision, and affect the limiting effect of the limiting block 6 on the support rod 2, a supporting assembly is provided on one side of the telescopic plate 7 and in the mounting groove, and the supporting assembly includes a second connecting block 24, a telescopic block 26 and a movable block 27. The second connecting block 24 is fixedly connected to one side of the fixed end of the telescopic plate 7, and a third elastic member 25 is provided on one side of the second connecting block 24. A connecting groove is provided on the inner wall of the mounting groove, and one end of the third elastic member 25 is fixedly installed with the connecting groove. The telescopic block 26 is hinged to the upper and lower sides of the second connecting block 24 respectively, and the movable block 27 is hinged to one end of the telescopic block 26. The movable block 27 is movably arranged in the mounting groove, and a movable opening 28 is provided on one side of the telescopic end of the telescopic plate 7. The second connecting block 24 is located in the movable opening 28, so that the second connecting block 24 will not block the extension and retraction of the telescopic plate 7. A groove is provided on the inner wall of the mounting groove, and the movable block 27 is movably connected to the inner wall of the groove for installing the telescopic block 26 and the movable block 27.

[0028] When the telescopic plate 7 deflects toward the outside of the fixed seat 5, it drives the second connecting block 24 to move toward the outside of the installation groove, so that the third elastic member 25 is stretched. When the second connecting block 24 moves, the telescopic block 26 extends and deflects. At the same time, the telescopic block 26 drives the movable block 27 to move along the inside of the groove. The telescopic plate 7 is supported and limited by the movement of the telescopic block 26 and the third elastic member 25. The third elastic member 25 can be a compression spring. When the telescopic plate 7 deflects toward the inside of the installation groove, the second connecting block 24 and the telescopic block 26 are deflected back to the inside of the groove through the action of the third elastic member 25, so that the telescopic block 26 and the movable block 27 are stored and protected.

[0029] Working principle: When in use, in the initial state, the limiting blocks 6 on the left and right sides of the fixing seat 5 are located outside the fixing seat 5 and away from the support rod 2, exposing the mounting pole 3 and the second flange 16. When the mounting pole 3 and the support rod 2 are installed, align the two limiting rods 17 at the bottom of the first flange 15 with the plug-in slot of the fixing rod 19, move the limiting rod 17 downward, and insert the limiting rod 17 into the inside of the plug-in slot, so that the first flange 15 fits one side of the second flange 16 and the screw holes are aligned. At the same time, the circular convexity at the bottom end of the moving rod 20 moves along the inclined surface of the moving block 21, squeezing the moving block 21, so that the third elastic member 25 stretches, and the moving block 21 drives the limiting rod 23 to plug into the limiting slot 18, thereby limiting the connection between the first flange 15 and the second flange 16.

[0030] When the limiting block 6 moves to one side of the limiting groove 18, the telescopic rod 10 is pulled to make the limiting block 6 plug into the limiting groove 8, and one side of the first connecting block 9 is in contact with the outer side of the support rod 2, limiting the support rod 2, and limiting the limiting block 6 is limited by the action of the telescopic plate 7, so that the connection between the mounting pole 3 and the support rod 2 remains stable.

[0031] At this time, screw the bolts into the screw holes again to fix the support rod 2 on the installation pole 3, so that the monitoring body 1 is fixed. When the limiting blocks 6 and the telescopic plates 7 on the left and right sides of the fixing seat 5 become loose after long-term use and the connection is unstable, by moving the limiting blocks 6 on the front and back sides of the fixing seat 5, under the action of the first connecting block 9, the telescopic rod 10, and the connecting rod 11, the front and back sides of the support rod 2 are limited. At the same time, the pushing plate 14 pushes the telescopic plate 7 to deflect for support and limitation, so that the installation pole 3 and the support rod 2 remain stable, which is convenient for switching the limiting blocks 6 and the telescopic plates 7, convenient for workers to operate, and convenient for monitoring the water surface evaporation raft.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
