Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a concrete pole top crack monitoring device, including a pole body 1, four sets of bolts are arranged at the bottom of the pole body 1, which is convenient for fixing the pole body 1 on the ground, the top plate of the pole body 1 is fixedly connected with a top cover 2, and the top of the pole body 1 is blocked by the top cover 2, and the inner wall of the pole body 1 is provided with a protective component 3, through which the protective component 3 is used to prevent excessive pressure on the movable plate 36, thereby causing damage to the pressure sensor 7, and a pressure block 6 is arranged on the protective component 3, by contacting the pressure block 6 with the pressure sensor 7 , thereby applying pressure to the pressure sensor 7. The protection component 3 is provided with a pressure sensor 7, and the pressure signal received by the pressure sensor 7 is transmitted to the controller 5 through the pressure sensor 7. The inner wall of the front bottom end of the pole body 1 is fixedly connected with the controller 5.

The protection component 3 is provided with a buffer component 4, and the buffer component 4 plays a buffering role on the movable plate 36 to prevent the pressure sensor 7 from being subjected to a large impact force and causing damage.

[0033] Reference Figure 2 and Figure 3 The protective component 3 includes a fixed plate 31, a through hole is passed through the top of the fixed plate 31, and a hinged plate 32 is hinged on the inner wall of the fixed plate 31, and the hinged plate 32 is symmetrically distributed in two groups. Through the hinge effect of the hinged plate 32, the hinged plate 32 can rotate around the hinge point, so as to open or close the top through hole of the fixed plate 31, and a slide groove 33 is provided on the right side of the hinged plate 32, and the slide groove 33 is symmetrically distributed in two groups. The inner wall of the slide groove 33 is slidably connected with a slider 34, and the slider 34 is symmetrically distributed in two groups. Through the moving effect of the slider 34, the hinged plate 32 is driven to rotate, and a connecting rod 35 is hinged on the right side of the slider 34, and the connecting rod 35 is symmetrically distributed in two groups. Through the moving effect of the connecting rod 35, the slider 34 is driven to slide along the inner wall of the slide groove 33, and the bottom of the connecting rod 35 is hinged with a movable plate 36.

[0034] Reference Figure 2 and Figure 4The buffer assembly 4 includes a sleeve 41, the inner wall of the sleeve 41 is elastically connected to the cylinder 42 through a spring 43, and the elastic force of the spring 43 plays a buffering role on the cylinder 42 and the movable plate 36. The inner wall of the sleeve 41 is provided with a sealing gasket 44, and two groups of sealing gaskets 44 are provided. The sealing gasket 44 has a certain elastic force, which has a sealing effect on the gap between the sleeve 41 and the cylinder 42 to prevent rainwater from contacting the pressure sensor 7 and affecting the pressure sensor 7. At the same time, it can squeeze the cylinder 42, thereby slowing down the movement speed of the cylinder 42 and playing a buffering effect.

[0035] Reference Figure 3 The outer wall of the fixed plate 31 is fixedly connected to the inner wall of the pole body 1. The fixing effect of the fixed plate 31 prevents the fixed plate 31 from falling off. The bottom of the movable plate 36 is elastically connected to the circular plate 37 through the reset spring 39. The elastic force of the reset spring 39 makes the movable plate 36 always keep moving upward without being affected by external force, driving the pressure block 6 to release the contact effect with the pressure sensor 7. The bottom of the movable plate 36 is fixedly connected to the guide rod 38. The guide rod 38 improves the stability of the reset spring 39 to avoid the reset spring 39 from deviating during operation. The top of the pressure block 6 is fixedly connected to the bottom of the movable plate 36. The fixing effect of the pressure block 6 prevents the pressure block 6 from falling off. The bottom of the pressure sensor 7 is fixedly connected to the top of the circular plate 37. The fixing effect of the pressure sensor 7 prevents the pressure sensor 7 from falling off. The pressure sensor 7 is electrically connected to the controller 5.

[0036] Reference Figure 2 and Figure 4 The bottom of the sleeve 41 is fixedly connected to the top of the circular plate 37, and the fixing effect of the sleeve 41 prevents the sleeve 41 from falling off. The top of the cylinder 42 is fixedly connected to the bottom of the movable plate 36, and the fixing effect of the cylinder 42 prevents the cylinder 42 from falling off. The outer periphery of the cylinder 42 is slidably connected to the inner wall of the sleeve 41, and the sliding effect of the movable plate 36 drives the cylinder 42 to slide. One end of the spring 43 is fixedly connected to the inner wall of the sleeve 41, and the other end of the spring 43 is fixedly connected to the bottom of the cylinder 42. There are four groups of springs 43 distributed in an annular array, and the fixing effect of the spring 43 prevents the spring 43 from falling off.

[0037] Reference Figure 2One end of the return spring 39 is fixedly connected to the bottom of the movable plate 36, and the other end of the return spring 39 is fixedly connected to the top of the circular plate 37. The fixing effect of the return spring 39 prevents the return spring 39 from falling off, which affects the resetting effect of the movable plate 36. The outer wall of the movable plate 36 is slidably connected to the inner wall of the pole body 1. The sliding effect of the movable plate 36 drives the two groups of connecting rods 35 to move at the same time, and drives the pressure block 6 to move vertically. The outer wall of the circular plate 37 is fixedly connected to the inner wall of the pole body 1. The fixing effect of the circular plate 37 prevents the circular plate 37 from falling off. The outer periphery of the guide rod 38 penetrates and is slidably connected to the inner wall of the circular plate 37.

[0038] Working principle: the staff installs the pole body 1 at a suitable position. When the pole body 1 is used for a long time and the top cover 2 is cracked, debris and rainwater will fall from the crack of the top cover 2 onto the fixed plate 31, and fall onto the movable plate 36 through the through hole opened on the top of the fixed plate 31, so that the movable plate 36 moves downward, and at the same time drives the pressure block 6 and the cylinder 42 to move downward, so that the cylinder 42 squeezes the spring 43. Through the elastic force of the spring 43, a buffering effect is played on the cylinder 42 and the movable plate 36. At the same time, the sealing gasket 44 arranged in the sleeve 41 can prevent rainwater from entering the pressure sensor 7, and the sealing gasket 44 can squeeze the cylinder 42, slow down the movement speed of the cylinder 42, and achieve a buffering effect on the movable plate 36.

[0039] When too much debris and rainwater accumulate on the movable plate 36, the pressure block 6 contacts the pressure sensor 7, and the pressure signal is transmitted to the controller 5 through the pressure sensor 7. The controller 5 reads and displays the pressure applied to the pressure sensor 7, so that the staff can monitor whether the top cover 2 is cracked. When the movable plate 36 moves downward, it can simultaneously drive the two groups of connecting rods 35 to move. The two groups of connecting rods 35 respectively drive the two groups of sliders 34 to slide along the inner wall of the slide groove 33, so that the two groups of hinged plates 32 rotate downward, closing the top through hole of the fixed plate 31, preventing subsequent debris from continuing to fall onto the movable plate 36, thereby protecting the movable plate 36 and the pressure sensor 7.

[0040] When the debris on the movable plate 36 is cleaned, the movable plate 36 moves upward through the elastic force of the reset spring 39, so that the two groups of connecting rods 35 and the two groups of sliders 34 drive the two groups of hinged plates 32 to flip upward, thereby opening the through hole of the fixed plate 31 for subsequent monitoring of the top cover 2.
