Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a safety monitoring device for road and bridge construction machinery. Background Art

[0002] Bridge and road construction are both relatively large projects with large construction volume and high construction technology requirements. A large number of construction workers are needed to work simultaneously, which brings certain pressure to the supervision of construction safety. Currently, most monitoring devices for construction safety are cameras. By installing cameras at multiple locations on the construction site, all-round monitoring of the construction site can be achieved.

[0003] However, the construction site environment is harsh, with a lot of dust and mud. The existing monitoring devices lack dust-proof devices. Long-term dust accumulation is bound to affect the service life of the monitoring devices. Long-term dust accumulation will also block the camera lens. Workers often forget to clean the lens during construction. Therefore, a monitoring device for construction safety is urgently needed to solve the above problems. Utility Model Content

[0008] By adopting the above technical solution, a clock circuit is set for timing. After the set time interval, the cleaning component works once to clean the lens. There is no need for manual on-site cleaning, and the automatic cleaning state is effectively achieved.

[0009] Preferably, the cleaning assembly includes a water pipe and an electric water stop valve. The water pipe is installed at a distance of 20 cm from the lens, and the direction of the water column sprayed from the water pipe is at a 45-degree angle to the plane direction of the lens.

[0010] By adopting the above technical solution, a water column is sprayed out from the water pipe, and the processor controls the opening and closing of the electric water stop valve and the retraction and expansion of the water column, thereby effectively realizing the automatic cleaning state.

[0011] Preferably, a pressure-boosting valve is installed on the water pipe, the pressure-boosting valve is arranged in parallel with the water-stop valve, and the pressure-boosting valve is arranged at an end away from the lens.

[0012] By adopting the above technical solution, a pressure valve is arranged on one side of the water stop valve. The pressure valve pressurizes the water column and then sprays it out, so that the water column has some power, which can more effectively clean the stains on the lens.

[0013] Preferably, the cleaning component includes a brush and a moving device for pushing the brush, the brush is mounted on the moving device, the moving device is mounted on one side of the lens, the moving direction of the brush is parallel to the plane direction of the lens, the moving device is connected to a processor, and the processor controls the opening and closing of the moving device according to timing.

[0014] By adopting the above technical solution, only using water for cleaning may result in incomplete cleaning, so adding a brush to clean the lens effectively realizes the state of cleaning the lens.

[0015] Preferably, the moving device comprises a cylinder, the cylinder comprises a cylinder barrel and a piston rod, the cylinder barrel of the cylinder is installed on one side of the lens, and the moving direction of the piston rod of the cylinder is horizontal to the plane direction of the lens.

[0017] Preferably, a protective net is provided on the outside of the lens, and the protective net surrounds the lens and the cleaning component inside for protection. A camera hole is provided on the protective net, and the plane of the lens is aligned with the camera hole.

[0018] By adopting the above technical solution, the protective net protects the lens and a camera hole is left on the lens, which effectively protects the lens without hindering the monitoring and shooting of the lens.

[0019] Preferably, a spring is installed at one end of the lens away from the lens plane, and the other end of the spring is connected to the protective net. A vertical pole is arranged at the lower end of the lens, and a spring is also installed between the vertical pole and the lens.

[0020] By adopting the above technical solution, springs are installed around the lens, and when stones and gravel hit the lens, a mitigation effect will occur, thereby effectively protecting the lens from damage.

[0021] Preferably, the mesh size of the protective net is no larger than 1 cm.

[0022] By adopting the above technical solution, if the protective mesh hole is too large, large stones may easily hit the lens, so the diameter of the protective mesh hole needs to be less than 1 mm.

[0023] In summary, the utility model has the following beneficial technical effects:

[0024] 1. By setting a clock circuit for timing, after the set time interval, the cleaning component works once to clean the lens, without the need for manual on-site cleaning, effectively achieving the state of automatic cleaning;

[0038] The mesh of the protective net 9 is not larger than 1 cm. If the mesh of the protective net 9 is too large, it is easy for large stones to hit the lens 1, so the diameter of the mesh of the protective net 9 needs to be smaller than 1 cm.

[0039] Reference Figure 4 and Figure 5 The cleaning component is connected to a processor 2, which is connected to a clock circuit 3. The clock circuit 3 is used for timing, and the processor 2 controls the opening and closing of the cleaning component according to the timing.

The processor 2 controls the opening and closing of the moving device according to the timing. The moving device includes a cylinder 8. The cylinder 8 includes a cylinder barrel and a piston rod. The cylinder barrel of the cylinder 8 is mounted on one side of the lens 1. The moving direction of the piston rod of the cylinder 8 is horizontal to the plane direction of the lens 1.

[0043] If only water is used for cleaning, the cleaning may not be done properly, so the brush 7 is added to clean the lens 1, which effectively realizes the state of cleaning the lens 1. Through the push of the cylinder 8, the automatic operation of the brush 7 is effectively realized.
