[0020] In order to better achieve the purpose of the present invention, the present invention also provides a method for digging holes and sampling using a portable photovoltaic module glass digging device, comprising the following steps:

[0021] Step 1: When in use, place the support ring on the glass plate, press the fixed suction cup, and the air in the fixed suction cup is discharged through the suction cup release module, so that the fixed suction cup is tightly fitted to the glass plate to avoid movement during the digging process; water is injected into the sponge block through the water injection hole to fill the sponge block with water; the placement plate maintains vertical movement under the limiting action of the support column, and a gravity block is added to the placement plate; the gravity block and the placement plate press down the rotating seat, and the rotating seat presses down the cutter head, so that the cutter head is tightly attached to the glass plate. At this time, the material picking suction cup in the cutter head is attached to the glass plate, and the air in the material picking suction cup is discharged through the unlocking block, the sleeve, the first connecting hole, the exhaust hole and the second moving groove; at this time, the variable force rotating block tilts outward, and the steel balls in the variable force rotating block are concentrated on one side of the outer accommodating cavity. The variable force rotating block pulls the connecting rod under the action of the gravity of the steel balls, and the connecting rod pulls the placement plate, so that the overall pressure of the placement plate on the rotating seat is less than the gravity of the placement plate;

[0022] Step 2: Start the motor to drive the installation shaft to rotate, and the installation shaft drives the rotating seat to rotate through the connecting block and the limiting slide groove. The rotation of the rotating seat drives the cutter head to rotate, and the glass plate is cut by the cutter head; the rotation of the cutter head drives the rotating disk, the round rod, the sleeve and the sponge block to rotate, and the moisture in the sponge block is discharged under the action of centrifugal force and the pressure of the downward movement of the cutter head; in this process, the placement plate presses down the rotating seat to drive the rotating seat to move downward, thereby providing feed force for the cutter head; the cutter head and the rotating seat move vertically downward, and the placement plate moves downward. The placement plate moves downward and drives the variable force rotating block to rotate through the connecting rod, so that the variable force rotating block gradually rotates inward; in this process, the steel balls in the outer accommodating chamber gradually move into the inner accommodating chamber through the connecting groove. The variable force rotating block moves, thereby gradually increasing the internal gravity of the variable force rotating block; the variable force rotating block gradually reduces the pulling force on the placement plate through the connecting rod until the steel ball in the variable force rotating block moves to one side of the inner accommodating chamber, at which time the gravity of the variable force rotating block and the steel ball presses on the placement plate; the pressure of the placement plate on the rotating seat gradually increases from less than the gravity of the placement plate to greater than the gravity of the placement plate; the placement plate drives the cutter head to move downward through the rotating seat, and the cutter head presses the sponge block so that the sponge block is compressed. During this process, the rotating disk and the round rod move upward, the reset spring is compressed, and at the same time, the air in the adsorption hole and the sleeve is discharged through the first connecting hole, the exhaust hole and the second moving groove, and the air is discharged in one direction through the action of the exhaust spring and the second conical block;

[0023] Step 3: After the hole is dug, the pulling block is pulled to drive the first conical block to move upward through the pulling rod, so that the first conical block is separated from the first conical groove, and the external air can enter the lower side of the fixed suction cup through the release hole and the first moving groove, so as to facilitate the fixed suction cup to separate from the glass plate; at this time, the material taking suction cup absorbs the circular glass plate cut from the center, and the round rod and the sleeve are kept in a tightened state, so that the sponge block is kept in a compressed state to prevent the sponge block from resetting and absorbing the debris produced by cutting on the glass plate;

[0024] Step 4: When moving the device to the collection and sampling position, push the placement plate, the rotating seat and the cutter head to move upward, and the placement plate drives the variable force rotating block to rotate upward through the connecting rod, so that the variable force rotating block is tilted outward again. At this time, the steel balls in the variable force rotating block flow into the outer accommodating chamber again to complete the reset; in this process, the rotating seat drives the cutter head to move upward, thereby driving the second conical block and the inclined block in the cutter head to move upward, so that the inclined block contacts the unlocking block at the bottom of the mounting shaft, and the inclined block is pushed to move by the unlocking block, and the inclined block drives the second conical block to disengage from the second conical groove, so that external air enters the first connecting hole, the exhaust hole, the second moving groove, the sleeve and the bottom of the material taking suction cup, and the sleeve and the round rod are reset under the action of the reset force of the reset spring, and the sponge block stretches and resets; the round glass plate falls off.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. In the initial state, the variable force propulsion module keeps the cutter head at a position higher than the bottom of the support mechanism, so that when the cutter head is placed, it contacts the placement panel, thereby protecting the cutter head and preventing the cutter head from scratching the placement panel;

[0026] 2. When in use, place the device on the glass plate of the photovoltaic module, and ensure the stability of the hole digging by the support of the supporting mechanism; then inject water into the convenient water injection module in the cutter head. After the water injection is completed, start the rotation drive module to drive the cutter head to rotate, and dig a hole in the glass plate through the cutter head. In this process, the variable force propulsion module drives the cutter head to move and provides a feed force for the cutter head to move downward. In addition, through the setting of the variable force propulsion module, the feed force on the cutter head increases as the cutting depth increases, thereby avoiding excessive force at the beginning of digging the hole and causing the glass plate to collapse. At the same time, as the cutting depth increases, the feed force is increased; in this process, the hole digging mechanism drives the convenient water injection module to rotate and squeeze the convenient water injection module, so that the water in the convenient water injection module gradually flows out during the hole digging process, thereby Avoid the collapse of the glass plate; after the hole is dug, operate the supporting mechanism to separate the device from the glass plate, and then lift the device. At this time, the convenient water injection module is still in a compressed state, so as to avoid the convenient water injection module being reset on the glass plate and causing the adsorption of debris generated by the hole; and the circular glass plate dug out of the glass plate is sucked tightly by the material taking suction cup in the hole digging mechanism; after the device is moved to the sampling position, the cutter head and the variable force propulsion module are operated to reset. In this process, the convenient water injection module and the material taking suction cup are released synchronously through the one-way exhaust module, and the convenient water injection module is released and reset, which is convenient for digging again and pushing the circular glass into the cutter head at the same time; the material taking suction cup is released, which is convenient for taking out the circular glass plate, so that the overall structure is simple and portable, and it is convenient to collect the circular glass plate in the cutter head.

The movement drives the variable force rotating block 323 to rotate through the connecting rod 325, so that the variable force rotating block 323 gradually rotates inwardly; during this process, the steel ball in the outer accommodating chamber 3231 gradually moves to the inner accommodating chamber 3232 through the connecting groove 3233, so that the internal gravity of the variable force rotating block 323 gradually increases; the pulling force of the variable force rotating block 323 on the placement plate 321 through the connecting rod 325 is gradually reduced until the steel ball in the variable force rotating block 323 moves to the side of the inner accommodating chamber 3232, at this time, the gravity of the variable force rotating block 323 and the steel ball presses on the placement plate 321; the pressure of the placement plate 321 on the rotating seat 314 is gradually increased from less than the gravity of the placement plate 321 to greater than the gravity of the placement plate 321; thereby, as the digging depth increases, the feed force of the cutter head 33 is increased;

[0053] The placement plate 321 drives the cutter head 33 to move downward through the rotating seat 314, and the cutter head 33 presses the sponge block 44, so that the sponge block 44 is compressed. During this process, the rotating disk 43 and the round rod 42 move upward, and the return spring 45 is compressed. At the same time, the air in the adsorption hole 47 and the sleeve 41 is discharged through the first connecting hole 61, the exhaust hole 62 and the second moving groove 63. The air is discharged in one direction through the exhaust spring 65 and the second conical block 64.

[0054] After the hole is dug, the pull block 245 is pulled through the pull rod 246 to drive the first conical block 244 to move upward, so that the first conical block 244 is separated from the first conical groove, so that the external air can enter the lower side of the fixed suction cup 23 through the release hole 241 and the first movable groove 243, so that the fixed suction cup 23 is easy to separate from the glass plate; at this time, the material taking suction cup 5 absorbs the circular glass plate cut from the center, and at the same time, the round rod 42 and the sleeve 41 are kept in a tightened state, so that the sponge block 44 is kept in a compressed state, so as to prevent the sponge block 44 from resetting to absorb the debris produced by cutting on the glass plate;

[0055] When the device is moved to the sampling collection position, the placement plate 321, the rotating seat 314 and the cutter head 33 are pushed to move upward, and the placement plate 321 drives the variable force rotating block 323 to rotate upward through the connecting rod 325, so that the variable force rotating block 323 is in an outward tilted state again. At this time, the steel balls in the variable force rotating block 323 flow into the outer accommodating chamber 3231 again to complete the reset; in this process, the rotating seat 314 drives the cutter head 33 to move upward, thereby driving the second conical block 64 and the inclined block 66 in the cutter head 33 to move upward, so that the inclined block 66 contacts the unlocking block 67 at the bottom of the mounting shaft 312, and the inclined block 66 is pushed to move by the unlocking block 67, and the inclined block 66 drives the second conical block 64 to disengage from the second conical groove, so that external air enters the first connecting hole 61, the exhaust hole 62, the second moving groove 63, the sleeve 41 and the bottom of the material taking suction cup 5, the sleeve 41 and the round rod 42 are reset under the action of the reset force of the reset spring 45, and the sponge block 44 stretches and resets; the circular glass plate falls off.

[0057] Step 1: When in use, place the support ring 22 on the glass plate, press the fixed suction cup 23, and the air in the fixed suction cup 23 is discharged through the suction cup release module 24, so that the fixed suction cup 23 is tightly fitted to the glass plate to prevent movement during the hole digging process; water is injected into the sponge block 44 through the water injection hole 46 to fill the sponge block 44 with water; the placement plate 321 keeps moving vertically under the limiting action of the support column 21, and a gravity block is added to the placement plate 321; the gravity block and the placement plate 321 press down the rotating seat 314, and the rotating seat 314 presses down the cutter head 33, so that the cutter head 33 Closely attached to the glass plate, the material-taking suction cup 5 in the cutter head 33 is attached to the glass plate, and the air in the material-taking suction cup 5 is discharged through the unlocking block 67, the sleeve 41, the first connecting hole 61, the exhaust hole 62 and the second movable groove 63; at this time, the variable force rotating block 323 is tilted outward, and the steel balls in the variable force rotating block 323 are concentrated on one side of the outer accommodating chamber 3231. Under the action of the gravity of the steel balls, the variable force rotating block 323 pulls the connecting rod 325, and the connecting rod 325 pulls the placing plate 321, so that the overall pressure of the placing plate 321 on the rotating seat 314 is less than the gravity of the placing plate 321;

[0058] The second step is to start the motor 311 to drive the installation shaft 312 to rotate, and the installation shaft 312 drives the rotating seat 314 to rotate through the connecting block 313 and the limiting sliding groove 315. The rotation of the rotating seat 314 drives the cutter head 33 to rotate, and the glass plate is cut by the cutter head 33; the rotation of the cutter head 33 drives the rotating disk 43, the round rod 42, the sleeve 41 and the sponge block 44 to rotate, and the moisture in the sponge block 44 is discharged under the action of centrifugal force and the pressure of the downward movement of the cutter head 33; in this process, the placement plate 321 presses the rotating seat 314 downward to drive the rotating seat 314 to move downward, thereby providing the cutting force for the cutter head 33; the cutter head 33 and the rotating seat 314 move vertically downward, the placement plate 321 moves downward, and the placement plate 321 moves downward to drive the variable force rotating block 323 to rotate through the connecting rod 325, so that the variable force rotating block 323 gradually rotates inward; in this process, the steel balls in the outer accommodating chamber 3231 are gradually accommodated inward through the connecting groove 3233 The cavity 3232 moves, thereby gradually increasing the internal gravity of the variable force rotating block 323; the variable force rotating block 323 gradually reduces the pulling force on the placement plate 321 through the connecting rod 325 until the steel ball in the variable force rotating block 323 moves to the side of the inner accommodating cavity 3232, at which time the gravity of the variable force rotating block 323 and the steel ball presses on the placement plate 321; the pressure of the placement plate 321 on the rotating seat 314 gradually increases from less than the gravity of the placement plate 321 to greater than the gravity of the placement plate 321; the placement plate 321 drives the cutter head 33 to move downward through the rotating seat 314, and the cutter head 33 presses the sponge block 44, so that the sponge block 44 is compressed. In this process, the rotating disk 43 and the round rod 42 move upward, the reset spring 45 is compressed, and at the same time, the air in the adsorption hole 47 and the sleeve 41 is discharged through the first connecting hole 61, the exhaust hole 62 and the second movable groove 63, and the air is discharged in one direction through the action of the exhaust spring 65 and the second conical block 64;

[0059] Step 3: After the hole is dug, the pull block 245 is pulled to drive the first conical block 244 to move upward through the pull rod 246, so that the first conical block 244 is separated from the first conical groove, so that the external air can enter the lower side of the fixed suction cup 23 through the release hole 241 and the first movable groove 243, so as to facilitate the fixed suction cup 23 to separate from the glass plate; at this time, the material taking suction cup 5 absorbs the circular glass plate cut from the center, and at the same time, the round rod 42 and the sleeve 41 are kept in a tightened state, so that the sponge block 44 is kept in a compressed state, so as to prevent the sponge block 44 from resetting to absorb the debris produced by cutting on the glass plate;

[0060] Step 4: When the device is moved to the sampling location, the placement plate 321, the rotating seat 314 and the cutter head 33 are pushed upward, and the placement plate 321 drives the variable force rotating block 323 to rotate upward through the connecting rod 325, so that the variable force rotating block 323 is tilted outward again. At this time, the steel balls in the variable force rotating block 323 flow into the outer accommodating chamber 3231 again to complete the reset; in this process, the rotating seat 314 drives the cutter head 33 to move upward, thereby driving the second conical block in the cutter head 33 64 and the inclined block 66 move upward, so that the inclined block 66 contacts the unlocking block 67 at the bottom of the mounting shaft 312, and the unlocking block 67 pushes the inclined block 66 to move, and the inclined block 66 drives the second conical block 64 to disengage from the second conical groove, so that external air enters the first connecting hole 61, the exhaust hole 62, the second movable groove 63, the sleeve 41 and the bottom of the material taking suction cup 5, and the sleeve 41 and the round rod 42 are reset under the action of the reset force of the reset spring 45, and the sponge block 44 stretches and resets; the round glass plate falls off.
