[0040] Example 1

[0041] Reference Figure 1-3 and 7, this embodiment provides a reflective sheet cleaning device for tunnel monitoring and measuring points.

[0042] The tunnel monitoring and measuring point reflector cleaning device comprises a cleaning mechanism 100 .

[0043] Specifically, the cleaning mechanism 100 includes a grip rod 101, the bottom grip of the grip rod 101 is covered with a non-slip grip sleeve 102 made of soft material, and the top of the grip rod 101 is rotatably connected to a switch table 103, and the outer periphery of the switch table 103 is provided with a plurality of mounting seats 104 in a circular array, and each mounting seat 104 is provided with a clamping member 105 in the inner cavity, and each mounting seat 104 is detachably provided with a mounting head 106, and the lower part of the outer wall of the mounting head 106 is symmetrical.

The replacement head 109 is a suction cup structure on which a new reflective sheet can be adsorbed. When the original reflective sheet is aged and damaged and cannot be used any longer, it can be scraped off by the shovel head 107 and then a new reflective sheet can be arranged through the replacement head 109.

[0044] Furthermore, the clamping member 105 includes a turntable 105a arranged inside the mounting seat 104, and the surface of the turntable 105a is provided with two traction grooves 105f in a circular array, and a traction block 105g is slidably embedded inside the traction groove 105f. At the same time, clamping blocks 105h are fixed on the top of the two traction blocks 105g, and the clamping blocks 105h penetrate into the recessed part of the mounting seat 104, and the two clamping blocks 105h are arranged facing each other.

[0045] Preferably, the traction groove 105f is arranged in an arc shape, and the distances from the two ends of the traction groove 105f to the center of the turntable 105a are not equal, so that when the turntable 105a rotates, the traction block 105g can slide inside it, and with the cooperation of the limiting opening on the surface of the concave part of the mounting seat 104 and the limiting guide of the clamping block 105h, the two clamping blocks 105h can move towards each other, so that the clamping block 105h is engaged or separated with the snap-in 106a at the bottom of the mounting head 106, thereby achieving the purpose of installing or disassembling the mounting head 106 and the mounting seat 104, making the loading and unloading of the mounting head 106 more convenient.

[0046] Furthermore, the ash receiving member 110 includes a movable ring 110a movably mounted on the outside of the gripping rod 101, and an ash hopper 110b for receiving the flaked ash impurities is fixed to the outside of the movable ring 110a. At the same time, with the rotation coordination of the movable ring 110a and the gripping rod 101, the ash hopper 110b can always maintain a vertical state under the action of gravity to ensure the continuous and stable use of the ash hopper 110b.

[0047] Example 2

[0048] Reference Figure 1-6 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0049] The tunnel monitoring and measuring point reflective sheet cleaning device further includes a switching mechanism 200 .

[0050] Specifically, the switching mechanism 200 includes a switching groove 201 opened on the surface of the grip 101, and a switching rod 202 that can swing therein passes through the interior of the switching groove 201, and rocking members 203 are rotatably connected to both sides of the switching rod 202, and a connecting member 204 is hinged at the end of the switching rod 202, so that the switching rod 202 can swing around the rocking member 203 and drive the connecting member 204 to move, and a control member 205 is also connected to the top of the connecting member 204, and a switching sleeve 206 is provided on the outer outer sleeve of the top of the control member 205, and the switching sleeve 206 is rotatably embedded in the top of the inner cavity of the grip 101, and a push plate 105d is also provided on the top of the control member 205.

[0051] The switching slot 201 is arranged in a W shape, which includes a vertically arranged swinging slot 201a, and the first adjusting slot 201b, the second adjusting slot 201c and the third adjusting slot 201d are sequentially opened in the upper, middle and lower sections on the left side of the swinging slot 201a, and the first disassembly and assembly slot 201e, the second disassembly and assembly slot 201f and the third disassembly and assembly slot 201g are sequentially opened in the upper, middle and lower sections on the right side of the swinging slot 201a, and the adjusting slot and the disassembly and assembly slot are all connected to the swinging slot 201a. At the same time, the widths of the first adjusting slot 201b, the third adjusting slot 201d and the first disassembly and assembly slot 201e and the third disassembly and assembly slot 201g are all greater than the widths of the second adjusting slot 201c and the second disassembly and assembly slot 201f, so as to facilitate cooperation with the switching rod 202 in the inclined state.

[0052] The rocking member 203 includes a clamping plate 203a with a hinge hole, and the hinge rods on both sides of the middle section of the switching rod 202 are rotatably connected to the clamping plate 203a through the hinge hole, and the switching rod 202 can be positioned by the clamping plate 203a. At the same time, connecting feet 203b are symmetrically fixed on the outer side of the clamping plate 203a, and a connecting groove 101b is also provided at the bottom of the inner wall of the gripping rod 101. The connecting groove 101b is arranged in an arc shape on the inner wall of the gripping rod 101, and the connecting foot 203b can slide inside the connecting groove 101b, so as to ensure the connection between it and the switching rod 202 while meeting the need for the switching rod 202 to shake left and right.

[0053] A positioning block 101a is fixedly arranged in the middle section of the inner wall of the grip 101, and the control member 205 includes a lifting sleeve 205a arranged inside the grip 101, and a positioning groove 205b cooperating with the positioning block 101a is reserved on the outer wall of the middle section of the lifting sleeve 205a, so that the lifting sleeve 205a that can be raised and lowered can be limited by the relative sliding between the positioning groove 205b and the positioning block 101a, so as to avoid the lifting sleeve 205a from rotating and affecting the subsequent cooperation between it and the switching sleeve 206, and a push column 205 is integrally arranged on the outer wall of the top end of the lifting sleeve 205a. c. At the same time, a rotating rod 205d is also provided inside the lifting sleeve 205a, and a rotating groove 205e is also reserved on the bottom surface of the rotating rod 205d, and an annular locking groove 205f is also reserved on the inner wall of the lifting sleeve 205a, and a locking ring 205g matching with the locking groove 205f is reserved on the outer wall of the rotating rod 205d, so that the relative stillness of the lifting sleeve 205a and the rotating rod 205d in the axial direction can be guaranteed through the cooperation between the locking ring 205g and the locking groove 205f, and the independent rotation of the rotating rod 205d relative to the lifting sleeve 205a is not affected.

[0054] The connecting member 204 includes a connecting seat 204a hinged to the end of the switching rod 202, and a rotating ball 204b is integrally arranged on the top of the connecting seat 204a, and the rotating ball 204b is slidably embedded in the rotating groove 205e. At the same time, the rotating groove 205e is arranged in a quarter arc clockwise at the bottom of the rotating rod 205d. When the switching rod 202 swings to the left, the rotating seat connected to its end can slide in the rotating groove 205e under the setting of the rotating ball 204b, so that the rotating seat and the rotating rod 205d are in a relative rotation state. At this time, the swing of the switching rod 202 will not affect the rotating rod 205d.

[0055] The switching sleeve 206 includes a rotating sleeve 206a arranged on the outer periphery of the top of the jacking sleeve 205a, and the top of the rotating sleeve 206a is fixed to the switching platform 103. A push groove 206b is arranged on the outside of the rotating sleeve 206a, and the push groove 206b is inclined along the outer wall of the rotating sleeve 206a. At the same time, the push column 205c on the top of the jacking sleeve 205a is slidably embedded in the push groove 206b. Therefore, under the mutual cooperation between the inclined push groove 206b and the push column 205c, when the jacking sleeve 205a performs a lifting movement inside the gripping rod 101, the rotating sleeve 206a can rotate under the push of the push column 205c, thereby realizing the relative switching of different tool positions on the switching platform 103, and the tool can be changed and used without rotating the gripping rod 101, making the use of the cleaning device more convenient.

[0056] Example 3

[0057] Reference Figure 1-7 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0058] A transmission tooth 105b is coaxially fixed to the bottom of the turntable 105a, and the outer side of the transmission tooth 105b is meshed with a rack 105c, and the outer side of the rack 105c is integrally connected with a push plate 105d, and the end of the push plate 105d close to the center of the switching table 103 is wedge-shaped, and the outer side of the convex plate on the surface of the push plate 105d is connected to a support spring 105e for supporting and limiting it, and the other end of the support spring 105e is in contact with the convex plate on the inner cavity of the mounting seat 104, so that the push plate 105d is supported by the elastic force of the support spring 105e itself, thereby preventing the push plate 105d from moving freely and affecting the stable operation of the turntable 105a through the transmission tooth 105b.

[0059] At the same time, the interior of the switching table 103 is also annularly distributed with a first push rod 208, a second push rod 209 and a third push rod 210, which correspond to the replacement head 109, the shovel head 107 and the wiping head 108 respectively. The lengths of the first push rod 208, the second push rod 209 and the third push rod 210 increase in equal length, that is, the distances between the first push rod 208, the second push rod 209 and the third push rod 210 and the switching table 103 increase in equal distances, and the first push rod 208, the second push rod 209 and the third push rod 210 are equidistantly increased. The tops of the push rod 209 and the third push rod 210 are both wedge-shaped, and the three can respectively cooperate with the wedge-shaped ends of the push plate 105d set inside the switching table 103, so that when the push rod rises, its top wedge surface can cooperate with the outer wedge surface of the push plate 105d, which can push the push plate 105d to move outward, and under the cooperation of the rack 105c and the transmission tooth 105b, the transmission tooth 105b is driven to rotate through the horizontal movement of the push plate 105d, thereby realizing the control of the cooperation state between the clamping block 105h and the installation head 106.

[0060] A top plate is also fixed to the top of the rotating rod 205d, and the top of the top plate is tilted upward in the clockwise direction. Therefore, when the switching rod 202 rotates to the right, the rotating rod 205d and the top plate can be pushed to rotate counterclockwise synchronously through the abutment between the rotating ball 204b and one end of the rotating groove 205e. Then, under the action of the inclined surface at the top of the top plate, the top plate can lift up the adjacent push rod, so that the installation head 106 can be unlocked and the cleaning tool can be replaced with the cooperation of the push rod and the clamping member 105.

[0061] When the cleaning device is used, the switch rod 202 is initially located in the middle position of the swing groove 201a. Relatively speaking, the push column 205c is located in the middle section of the push groove 206b outside the rotating sleeve 206a. At this time, the shovel head 107 is located on the side opposite to the switch rod 202. Then, the switch rod 202 is pushed to the right to make it enter the second adjustment groove 201c. The position of the switch rod 202 is fixed by the second adjustment groove 201c, thereby ensuring the stability of the position of the shovel head 107. At this time, the user can hold the grip 101 to extend the device to the measuring point, and the shovel head 107 can be used to scrape and clean the surface of the reflective sheet. When the cleaning is completed and the user needs to wipe the surface of the reflective sheet, the switch rod 202 can be pushed back to the swing groove 201a again, and the switch rod 202 can be pushed upward to make the switch rod 202 rotate around the clamping plate 203a, and drive the lifting sleeve 207 under the action of the connecting member 204. 05a moves downward, so that the push column 205c can push the push slot 206b to rotate, so that the switching table 103 rotates clockwise, thereby the end of the wiping head 108 can be rotated to the side opposite to the switching rod 202, and after the adjustment is completed, the switching rod 202 is toggled to the left to move it into the first adjustment slot 201b, so that the switching rod 202 is fixed again, and the user can wipe and clean the reflective sheet through the wiping head 108 at this time, and when the reflective sheet needs to be replaced, the switching rod 202 can be toggled downward inside the swing slot 201a, and at this time, the lifting sleeve moves upward under the action of the connecting member 204, so that the switching table 103 rotates counterclockwise, and the tool is switched again, and the replacement head 109 can be rotated to the side opposite to the switching rod 202 to replace the reflective sheet, and during the operation, the switching rod 202 is pushed into the third adjustment slot 201d to position the low-position switching rod 202;

[0062] When it is necessary to disassemble the shovel head 107, the wiping head 108 or the replacement head 109, when one of the three is switched to the side directly opposite the switching rod 202, the corresponding push rod is synchronously rotated to the adjacent side of the top plate. At this time, the switching rod 202 is toggled to the right, and the switching rod 202 drives the rotating rod 205d to rotate counterclockwise under the operation of the connecting member 204, and with the cooperation of the top plate and the corresponding push rod, the transmission of the corresponding clamping member 105 is realized, so that the clamping member 105 releases the restriction on the fixed head at the bottom of the shovel head 107, the wiping head 108 or the replacement head 109. At this time, the fixed head can be taken out for replacement. After the replacement is completed, the switching rod 202 is dialed into the swing groove 201a to realize the clamping member 105 locking the fixed head again. Through the coordinated setting among the switching slot 201, the switching rod 202, the control member 205 and the switching sleeve 206, the position of the cleaning tool can be adjusted by only turning the switching rod 202, so that the user does not need to rotate the grip 101 when using it, and the use of the cleaning device is more convenient. At the same time, the accuracy of the position change when using different cleaning tools is guaranteed. The user does not need to debug the fit between the corresponding cleaning tool and the reflective sheet of the measuring point again after adjustment, which improves the cleaning efficiency of the reflective sheet. In addition, with the cooperation of the clamping member 105 and multiple push rods, the disassembly control of different cleaning tools can also be realized through the switching rod 202, so that different cleaning tools can be quickly and accurately replaced.
