综上所述，本发明具有以下有益效果：In summary, the present invention has the following beneficial effects:
当井盖出现破损时，相应位置的监测线圈即出现断裂，进而控制器所监测到监测线圈阻抗增大，达到判断出井盖本体出现破损情况，实现精准监测井盖本体破损情况。When the manhole cover is damaged, the monitoring coil at the corresponding position will break, and the impedance of the monitoring coil detected by the controller will increase, thereby judging that the manhole cover body is damaged and realizing accurate monitoring of the damage of the manhole cover body.
当井盖本体出现沉降时，配重块相对于滑轮移动，并且配重块与井盖之间的距离增加，且是双倍增加，距离监测器监测到配重块位置变化并对控制器输出信号，并通过控制器判断井盖沉降。When the manhole cover body sinks, the counterweight moves relative to the pulley, and the distance between the counterweight and the manhole cover increases and doubles. The distance monitor detects the change in the position of the counterweight and outputs a signal to the controller, which then determines the sinking of the manhole cover.
导轮能够沿滑杆滑移，并且通过限位轮可以有效避免导轮脱离滑杆，当打开井盖时，向上翻转井盖本体，导轮沿滑杆朝向井盖与井壁铰接端方向滑移，且线缆与井壁连接端至滑轮之间距离缩短，并适应井盖本体的位置变化，避免翻转井盖时导致线缆张紧而影响监测精确度；另外通过导轮的移动，起到滑轮及配重块避让效果，即翻转井盖本体时，配重块位于窨井侧壁位置，方便工人进行操作；当盖合井盖本体时，由于滑杆呈弧形，导轮受配重块重力作用，滑移至滑杆弧形底部位置，从而方便确定导轮及配重块相对位置，确保距离监测器能够正常监测。The guide wheel can slide along the sliding rod, and the limiting wheel can effectively prevent the guide wheel from detaching from the sliding rod. When the manhole cover is opened, the manhole cover body is flipped upward, and the guide wheel slides along the sliding rod toward the hinged end of the manhole cover and the well wall. The distance between the connecting end of the cable and the well wall to the pulley is shortened, and it adapts to the position change of the manhole cover body to avoid the cable tension and affect the monitoring accuracy when the manhole cover is flipped. In addition, the movement of the guide wheel can achieve the avoidance effect of the pulley and the counterweight block, that is, when the manhole cover body is flipped, the counterweight block is located at the side wall of the manhole, which is convenient for workers to operate. When the manhole cover body is closed, due to the arc shape of the sliding rod, the guide wheel is affected by the gravity of the counterweight block and slides to the bottom position of the arc of the sliding rod, thereby facilitating the determination of the relative positions of the guide wheel and the counterweight block, ensuring that the distance monitor can monitor normally.
当滑移架相对于滑杆移动至滑杆底部位置时，磁吸块抵接磁石并且磁吸块与磁石吸附，进而达到固定滑移架的效果，避免井盖受振动而导致滑移架滑动，提升沉降监测的精确度。When the sliding frame moves to the bottom position of the sliding bar relative to the sliding bar, the magnetic block abuts against the magnet and the magnetic block is adsorbed by the magnet, thereby achieving the effect of fixing the sliding frame, preventing the sliding frame from sliding due to vibration of the manhole cover, and improving the accuracy of settlement monitoring.

When the manhole cover is opened, the manhole cover body 1 is flipped upward, and the guide wheel 11 slides along the slide bar 9 toward the hinged end of the manhole cover and the well wall, and the distance between the cable 7 and the well wall connection end to the pulley 8 is shortened, and it adapts to the position change of the manhole cover body 1 to avoid the cable 7 being tensioned and affecting the monitoring accuracy when the manhole cover is flipped. In addition, through the movement of the guide wheel 11, the pulley 8 and the counterweight 5 have a avoidance effect, that is, when the manhole cover body 1 is flipped, the counterweight 5 is located at the side wall of the manhole, which is convenient for workers to operate. When the manhole cover body 1 is closed, due to the arc shape of the slide bar 9, the guide wheel 11 is affected by the gravity of the counterweight 5 and slides to the bottom position of the arc of the slide bar 9, thereby facilitating the determination of the relative positions of the guide wheel 11 and the counterweight 5, ensuring that the distance monitor 6 can monitor normally.
所述滑移结构与所述井盖本体1之间设置有限定滑轮8位置并确保配重块5位于距离监测器6正下方的定位结构。定位结构包括设置于所述井盖下端面的磁石14、设置于所述滑移架10并能够被磁石14吸附的磁吸块15，磁吸块15材质可以为铁等，所述磁石14吸附磁吸块15时，所述导轮11位于所述滑杆9弧形底部位置，所述滑移架10沿滑杆9滑移后，磁吸块15能够抵接磁石14。当滑移架10相对于滑杆9移动至滑杆9底部位置时，磁吸块15抵接磁石14并且磁吸块15与磁石14吸附，进而达到固定滑移架10的效果，避免井盖受振动而导致滑移架10滑动，提升沉降监测的精确度。A positioning structure is provided between the sliding structure and the manhole cover body 1 to limit the position of the pulley 8 and ensure that the counterweight 5 is located directly below the distance monitor 6. The positioning structure includes a magnet 14 provided on the lower end surface of the manhole cover, and a magnetic block 15 provided on the sliding frame 10 and capable of being adsorbed by the magnet 14. The material of the magnetic block 15 may be iron or the like. When the magnet 14 adsorbs the magnetic block 15, the guide wheel 11 is located at the bottom of the arc of the slide bar 9. After the slide bar 10 slides along the slide bar 9, the magnetic block 15 can abut against the magnet 14. When the slide bar 10 moves to the bottom of the slide bar 9 relative to the slide bar 9, the magnetic block 15 abuts against the magnet 14 and the magnetic block 15 is adsorbed by the magnet 14, thereby achieving the effect of fixing the slide bar 10, preventing the slide bar 10 from sliding due to vibration of the manhole cover, and improving the accuracy of settlement monitoring.
本实施例中，井盖本体1设置有用于监测窨井内气体的气体监测器16、用于监测窨井内液位的液位监测器17，气体监测器16、液位监测器17为现有技术，在此不赘述，并且气体监测器16、液位监测器17与控制器3电信号连接。所述井盖本体1上端面开设有安装腔18，所述安装腔18内设置有用于结构太阳能的太阳能电池板19、用于储存电能的蓄电池20，所述安装腔18填充有透明树脂胶，安装腔18内设置有LED灯板21，所述LED灯板21光源朝向呈水平设置。LED灯板21、蓄电池20均与控制器3电连接。In this embodiment, the manhole cover body 1 is provided with a gas monitor 16 for monitoring the gas in the manhole and a liquid level monitor 17 for monitoring the liquid level in the manhole. The gas monitor 16 and the liquid level monitor 17 are prior art and are not described here in detail. The gas monitor 16 and the liquid level monitor 17 are electrically connected to the controller 3. The upper end surface of the manhole cover body 1 is provided with an installation cavity 18, and the installation cavity 18 is provided with a solar cell panel 19 for structural solar energy and a battery 20 for storing electrical energy. The installation cavity 18 is filled with transparent resin glue, and the installation cavity 18 is provided with an LED light board 21, and the light source of the LED light board 21 is horizontally arranged. The LED light board 21 and the battery 20 are both electrically connected to the controller 3.
实施例2，与实施例1不同之处在于：如图5和图6所示，沉降监测机构包括设置于所述井盖本体1下端面的导向轮22、设置于所述井盖本体1下端面的连接部23、设置于所述连接部23的弹性件24、一端连接于所弹性件24且另一端固定于井壁的拉绳25，所述拉绳25绕于所述导向轮22，拉绳25连接井壁的一端靠近于井壁底部位置，并且导向轮22、连接部23排列方向呈垂直于井盖本体翻转方向。弹性件24固定与连接部23，且弹性件与拉绳25连接，本实施例中，弹性件24可以为拉簧或卷簧等。所述连接部23设置有用于监测拉绳25与弹性件24连接端相对于连接部23位置的距离监测器6，距离监测器6与控制器3电信号连接，距离监测器6为现有技术，在此不赘述。所述导向轮22靠近于所述井盖本体1与井壁铰接端位置，且所述拉绳25所在平面垂直于井盖本体1翻转方向。Embodiment 2 is different from Embodiment 1 in that: as shown in FIG. 5 and FIG. 6 , the settlement monitoring mechanism includes a guide wheel 22 arranged on the lower end surface of the manhole cover body 1, a connecting portion 23 arranged on the lower end surface of the manhole cover body 1, an elastic member 24 arranged on the connecting portion 23, and a pull rope 25 connected to the elastic member 24 at one end and fixed to the well wall at the other end, the pull rope 25 is wound around the guide wheel 22, one end of the pull rope 25 connected to the well wall is close to the bottom of the well wall, and the arrangement direction of the guide wheel 22 and the connecting portion 23 is perpendicular to the flipping direction of the manhole cover body. The elastic member 24 is fixed to the connecting portion 23, and the elastic member is connected to the pull rope 25. In this embodiment, the elastic member 24 can be a tension spring or a coil spring. The connecting portion 23 is provided with a distance monitor 6 for monitoring the position of the connecting end of the pull rope 25 and the elastic member 24 relative to the connecting portion 23. The distance monitor 6 is connected to the controller 3 by electrical signals. The distance monitor 6 is a prior art and will not be described here. The guide wheel 22 is close to the hinged end of the manhole cover body 1 and the manhole wall, and the plane where the pull rope 25 is located is perpendicular to the flipping direction of the manhole cover body 1.
在检测井盖沉降时，弹性件24被拉长，即弹性件24与拉绳25连接端距离连接部23边长，距离监测器6监测到并对控制器3输出信号，从而能够监测到井盖下沉；另外当打开井盖时，即翻转井盖本体1，由于导向轮22靠近于井盖本体1与井壁铰接端，因而翻转井盖本体1时，拉绳25及弹性件24整体伸长量变化不大，不至于导致弹性件24过渡拉长而影响使用。When detecting the sinking of the manhole cover, the elastic member 24 is stretched, that is, the connection end of the elastic member 24 and the pull rope 25 is separated from the side length of the connecting portion 23, and the distance monitor 6 detects it and outputs a signal to the controller 3, thereby being able to monitor the sinking of the manhole cover; in addition, when the manhole cover is opened, that is, the manhole cover body 1 is turned over, since the guide wheel 22 is close to the hinged end of the manhole cover body 1 and the well wall, when the manhole cover body 1 is turned over, the overall elongation of the pull rope 25 and the elastic member 24 does not change much, so as not to cause excessive elongation of the elastic member 24 and affect its use.
