Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of opening and closing monitoring equipment, in particular to a manhole cover opening and closing monitoring equipment based on light sensing. Background Art
[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material.
[0003] When blocking the entrance, it is necessary to cover the entrance with a manhole cover. In order to prevent the loss of the manhole cover and cause people or objects to fall, it is necessary to monitor the opening and closing of the manhole cover through monitoring equipment.
[0004] The existing monitoring method for manhole covers is to install a photosensitive device on the inner wall of the well. When the well is opened, external light shines on the photosensitive device, and the photosensitive device transmits the changes in light to the terminal for display. However, the manhole cover is used for drainage while covering the well. When water flows through the manhole cover into the well, the external water mixture will fall onto the photosensitive device, blocking the photosensitive device and affecting its normal use.
[0005] Furthermore, the existing light sensing device needs to be installed on the inner wall of the well before use. The inner wall of the well is usually not vertical, which will cause the light sensing device to tilt during installation. The existing light sensing device cannot be adjusted in angle after installation. Utility Model Content
[0006] The purpose of the utility model is to provide a manhole cover opening and closing monitoring device based on light sensing to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a manhole cover opening and closing monitoring device based on light sensing, including a light sensing device and a cleaning brush located on the top of the light sensing device; the outer wall of the light sensing device is connected to a shell through a fastener, the outer wall of the shell is connected to the bottom of a support column through a fastener, the top of the support column is connected to a telescopic column in an embedded manner, the top of the telescopic column is connected to a glass cover through a fastener, one side of the shell is connected to one end of a transverse column through a fastener, the end of the transverse column away from the shell is connected to an extension column in an embedded manner, the other end of the extension column is connected to the bottom of the bracket through a fastener, the inner side of the bracket is connected to the cleaning brush through a fastener, the end of the cleaning brush away from the bracket is connected to a non-woven fabric through sewing, and a mounting plate is provided at the bottom of the shell, and the mounting plate is connected to the threaded column through a thread.
[0008] Preferably, the interior of the support column is connected to one end of the first elastic member via a fastener, and the end of the first elastic member away from the support column is connected to the end of the telescopic column away from the glass cover via a fastener.
[0009] Preferably, the interior of the transverse column is connected to one end of the second elastic member via a fastener, the other end of the second elastic member is connected to one end of the extension column via a fastener, and one end of the threaded column is connected to the rubber block via a fastener.
[0010] Preferably, the bottom of the glass cover is connected to the top of the telescopic shell through a fastener, and one end of the telescopic shell away from the glass cover is connected to the inner wall of the shell body in an embedded manner.
[0011] Preferably, a pulley is provided at one end of the bracket away from the extension column, the pulley is connected to the bracket in a rotated manner, and the pulleys are distributed in a mirror image on the bracket.
[0012] Preferably, the bottom of the shell is connected to one end of the connecting block through a fastener, the end of the connecting block away from the bottom of the shell is connected to the top of the protrusion through a rotating column, and the bottom of the protrusion is connected to the top of the mounting plate through a fastener.
[0013] Preferably, both ends of the rotating column are connected to the connecting block via a rotating shaft, and the rotating column is connected to the protrusion via a fastener.
[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0015] The utility model can prevent foreign objects from blocking the light sensing device by arranging a cleaning brush and a glass cover. When water flows into the inside of the well through the manhole cover, the water carries the foreign objects onto the glass cover. The downward impact force of the water and the weight of the foreign objects push the glass cover to move downward. The movement of the glass cover drives the telescopic column to squeeze the first elastic member inside the supporting column. The movement of the glass cover drives the telescopic shell to move to the inside of the shell. When the glass cover moves to the same height as the bracket, the second elastic member pushes the bracket to move to the glass cover through the pulley through the extension column. The movement of the bracket drives the cleaning brush to move. The cleaning brush pushes and wipes the foreign objects on the glass cover through the non-woven fabric. When the water no longer impacts the glass cover, the elastic member pushes the glass cover upward through the telescopic column through the rebound force of the elastic member. The glass cover pushes the bracket to move to one side again through the pulley, thereby achieving the cleaning work of the glass cover, effectively preventing foreign objects from blocking the light sensing device, and reflecting the practicality of the device.
[0016] Second, the utility model can adjust the angle of the installed light-sensing device by setting a rotating column and a threaded column. When the monitoring device needs to be installed, the mounting plate is fixed to the inner wall of the well through the through holes on the mounting plate with bolts. When the installed light-sensing device is in a tilted state, the threaded column on the tilted side is rotated downward, and then the threaded column on the tilted side is rotated upward. The threaded column pushes the bottom of the shell through the rubber block, and the connecting block at the bottom of the shell is rotated on the protrusion through the rotating column until it is adjusted to a suitable angle, thereby achieving the effect of adjusting the angle of the light-sensing device without the need for reinstallation.

[0034] Through the above technical solution, the housing 1 is used to support the photosensitive device 3 and to protect the photosensitive device 3 to prevent objects from falling and hitting the photosensitive device 3 and causing damage to the photosensitive device 3.
[0035] Specifically, both ends of the rotating column 20 are connected to the connecting block 18 via a rotating shaft, and the rotating column 20 is connected to the protrusion 19 via a fastener.
