[0002] The grid planning on-site exploration and detection device is installed on the outside of the cable during grid planning and construction to conduct mobile exploration and detection of the cable grid.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0020] See also Figures 1 to 5 This embodiment provides a technical solution: a power grid planning on-site exploration and detection device, including: a fixed shell 1, two sets of walking components, a displacement detection component, a controller 8, a first driving mechanism, a second driving mechanism, a detection head 9, and a detection head rotation mechanism; the walking component includes a bracket 2, an upper walking wheel 3, a lower walking wheel 4, a first guide rod 5, a guide hole, a limit plate 6 and a spring 7.

[0021] More specifically, in this embodiment: during installation, the power grid planning on-site exploration and detection device is placed at the cable to be detected, the upper and lower wheels 3 and 4 corresponding to each other are moved away from each other, and then the cable is passed between the upper and lower wheels 3 and 4, and the upper and lower wheels 3 and 4 are loosened, and the upper and lower wheels 3 and 4 are respectively pressed against the upper and lower ends of the cable by the elastic force of the spring 7, so that the upper wheels 3 of the two groups of walking components of the first driving mechanism rotate, so that the power grid planning on-site exploration and detection device moves on the cable; The displacement detection component is arranged on the front walking component in the walking direction of the power grid planning on-site exploration and detection device. The distance between the walking wheel 3 and the lower walking wheel 4 of the front walking component is monitored by the displacement detection component. The displacement detection component transmits the detected data signal to the controller 8 in real time. When the distance between the walking wheel 3 and the lower walking wheel 4 changes, it means that the cable here may have problems such as cross-section thinning, loose strands, and broken strands. The controller 8 sends control signals to the first drive mechanism and the second drive mechanism respectively to control the first drive mechanism to reduce the rotation speed, so that the speed of the power grid planning on-site exploration and detection device walking on the cable is slowed down, so that the detection head 9 stays at the part where the cable has problems for a longer time, the picture taken by the detection head 9 is clearer, and the detection accuracy is improved; the second drive mechanism is controlled to start, and the second drive mechanism drives the detection head rotation mechanism to operate. The detection head 9 is driven to rotate around the cable, so that the detection head 9 can rotate around the cable while moving radially, and then the detection head 9 performs a spiral motion on the outer surface of the cable. Since the picture taken by the detection head 9 is divergent, the detection head can take a full-range picture of the parts where the cable may have problems, thereby improving the accuracy of cable exploration and detection; when the displacement detection component detects that the distance between the walking wheel 3 and the lower walking wheel 4 becomes the set value, the controller 8 sends a control signal to the first drive mechanism and the second drive mechanism again after a certain period of time, that is, after the detection head 9 moves out of the part where the cable has problems, to control the first drive mechanism to resume a faster rotation speed, so that the power grid planning on-site exploration and detection device continues to move faster and at a uniform speed on the cable, thereby improving the detection rate of the entire power grid; the second drive mechanism is controlled to stop working.

[0023] More specifically, in this embodiment: when the second driving mechanism is working and drives the detection head rotating mechanism to operate, the second driving mechanism synchronously drives the piston reciprocating movement mechanism to operate, so that the piston assembly 10 performs a reciprocating suction and blowing action. When the piston assembly 10 performs an air suction action, a negative pressure is generated inside the piston assembly 10, and the external air is filtered through the filter 14 and then sucked into the piston assembly 10 through the air intake hood 13 and the air intake pipe 11. When the piston assembly 10 performs an air blowing action, the sucked gas is blown out from the air outlet pipe 12 and the air outlet hood 15. When the gas is blown out from the air outlet hood 15, the detection head 9 is just rotated to the air outlet hood 15, thereby blowing off the dust at the lens of the detection head 9, thereby improving the clarity of the picture taken by the detection head 9; When the piston reciprocating mechanism is in operation, the cleaning brush reciprocating mechanism is driven to operate, driving the cleaning brush 16 to reciprocate on the outer surface of the filter 14, and the dust attached to the surface of the filter 14 is removed by the cleaning brush 16 to prevent the dust from clogging the filter 14 and affecting the air intake effect of the piston assembly 10.

[0042] Working principle: When the power grid planning on-site exploration and detection device is used, the following steps are involved: Step S1: During installation, the power grid planning on-site exploration and detection device is placed at the cable to be detected, and the cable is passed between the upper running wheel 3 and the lower running wheel 4, and through the middle of the rotating mechanism of the detection head, and the upper running wheel 3 and the lower running wheel 4 are respectively pressed against the upper and lower ends of the cable by the elastic force of the spring 7; Step S2: The upper walking wheels 3 of the two walking assemblies of the first driving mechanism rotate, so that the power grid planning on-site exploration and detection device moves at a relatively fast and uniform speed on the cable; the distance between the walking wheel 3 and the lower walking wheel 4 of the front walking assembly is monitored by the displacement detection assembly, and the displacement detection assembly transmits the detected data signal to the controller 8 in real time; Step S3: When the distance between the walking wheel 3 and the lower walking wheel 4 changes, that is, when the cable here may have problems such as thinning of the cross section, loose strands, and broken strands, the controller 8 sends control signals to the first drive mechanism and the second drive mechanism respectively, controls the first drive mechanism to reduce the rotation speed, so that the speed of the power grid planning on-site exploration and detection device walking on the cable is slowed down; controls the second drive mechanism to start, and the second drive mechanism drives the detection head rotation mechanism to operate, driving the detection head 9 to rotate around the cable, so that the detection head 9 can rotate around the cable while moving radially, and then the detection head 9 can perform spiral motion on the outer surface of the cable. Since the picture taken by the detection head 9 is divergent, the detection head can take all-round pictures of the parts of the cable where problems may occur; Step S4: When the second driving mechanism is working and drives the detection head rotating mechanism to operate, the second driving mechanism synchronously drives the piston reciprocating movement mechanism to operate, so that the piston assembly 10 performs a reciprocating suction and blowing action, and the outside air is filtered through the filter screen 14, and then sucked into the piston assembly 10 through the air intake hood 13 and the air intake pipe 11, and then the sucked gas is blown out from the air outlet pipe 12 and the air outlet hood 15. When the gas is blown out from the air outlet hood 15, the detection head 9 is just rotated to the air outlet hood 15, so that the dust at the lens of the detection head 9 is blown off; Step S5: When the piston reciprocating mechanism is in operation, the cleaning brush reciprocating mechanism is driven to operate, driving the cleaning brush 16 to reciprocate on the outer surface of the filter 14, and the dust attached to the surface of the filter 14 is removed by the cleaning brush 16 to prevent the dust from clogging the filter 14 and affecting the air intake effect of the piston assembly 10; Step S6: When the displacement detection component detects that the distance between the walking wheel 3 and the lower walking wheel 4 becomes the set value, after a certain period of time, that is, after the detection head 9 is completely moved out of the position where the cable has problems, the controller 8 again sends a control signal to the first drive mechanism and the second drive mechanism to control the first drive mechanism to restore a faster rotation speed, so that the power grid planning on-site exploration and detection device continues to move at a faster uniform speed on the cable, thereby improving the detection rate of the entire power grid; and controls the second drive mechanism to stop working.
