Description

Technical Field

[0001] This application relates to the technical field of road construction equipment, and in particular to an auxiliary device for on-site core sampling and road surface cleaning. Background Technology

[0002] During highway construction and acceptance testing, highway thickness is one of the key testing items.

[0003] Currently, core drilling is commonly used for road thickness testing. This method involves a core drilling machine driving a drill bit to drill at a corresponding location on the road to collect samples. During operation, a water pump on the core drilling machine continuously supplies cooling water to the drill bit to ensure it is adequately cooled. However, the sampling process inevitably generates wastewater containing roadbed residue and dust, which can contaminate the road surface. This wastewater may even seep into the road surface, negatively impacting the substructure and subgrade.

[0004] To address the aforementioned problems, a wastewater collection device for road core drilling machines has been developed. This device includes a collection cylinder with a siphon pipe connected to its side wall. The other end of the siphon pipe is inserted into a container for collecting wastewater, such as a water bottle, plastic bag, or bucket. During core drilling, the collection cylinder is fitted around the drill bit. The drill drills inside the collection cylinder, and cooling water is simultaneously discharged into it. The wastewater is then collected through the siphon pipe into the wastewater collection device. This device, used in conjunction with the core drilling machine for core sampling, effectively reduces wastewater leakage.

[0005] Regarding the aforementioned technologies, in actual use, the connection between the siphon pipe and the side wall of the collection cylinder is set vertically at intervals from the road surface. This results in the siphon pipe being unable to empty all the sewage in the collection cylinder, leaving some sewage inside. Therefore, when the collection cylinder is finally disassembled, the remaining sewage will still pollute part of the ground. Summary of the Invention

[0006] This application provides an auxiliary device for cleaning road surfaces during on-site core drilling, the purpose of which is to collect wastewater during the core drilling sampling process and reduce wastewater residue on the road surface, thereby reducing wastewater pollution to the road surface.

[0007] The technical solution of the on-site core sampling and pavement cleaning auxiliary device provided in this application is as follows: An auxiliary device for on-site core sampling and road surface cleaning includes a water collection cylinder, a drain faucet is provided on the side wall of the water collection cylinder, the inlet of the drain faucet is connected to the water collection cylinder, a drain pipe is detachably connected to the drain faucet, and the drain pipe is connected to the outlet of the drain faucet; one end of the water collection cylinder is provided with a water suction component for absorbing sewage, the water suction component is detachably connected to the water collection cylinder, and a water suction hole is provided through the water suction component, the water suction hole is coaxially connected to the water collection cylinder.

[0008] By adopting the above technical solution, the coordinated arrangement of the water collection cylinder, drain faucet, and drain pipe ensures that before the core drilling machine begins operation, the water collection cylinder is fitted around the outside of the drill bit. Therefore, during core drilling, the water cooling the drill bit collects in the water collection cylinder, and as the drilling continues, the wastewater level in the collection cylinder rises. When the core drilling process ends, or when the water level in the collection cylinder becomes too high, the drain faucet is opened, and the wastewater in the collection cylinder is transported through the drain faucet and drain pipe to the corresponding container, thus achieving wastewater collection.

[0009] Based on this, a water suction component is installed on the lower side of the water collection cylinder. This component has suction holes, which provide drilling space for the core drilling machine's drill bit, ensuring its normal operation. The suction component can be made of absorbent sponge, absorbent soil, or other water-absorbing materials. After the drain faucet has been running for a period of time, some wastewater may not be able to drain through due to the height difference between the faucet and the ground. The water suction component can then absorb this wastewater, preventing it from remaining on the road surface.

[0010] Therefore, by using a water-absorbing device to extract sewage that cannot be discharged from the drain faucet, the sewage collection rate is improved, thereby reducing sewage residue on the road surface and reducing sewage pollution to the road surface.

[0011] Optionally, an installation mechanism is provided between the water-collecting cylinder and the water-absorbing component. The installation mechanism includes an installation plate with a through-hole and an installation groove through-hole on the side wall of the installation plate, the installation groove communicating with the through-hole. One end of the water-collecting cylinder facing the water-absorbing component is detachably connected to the installation plate, and the through-hole is coaxially connected with the water-collecting cylinder. The water-absorbing component is inserted into the installation groove, and the water-absorbing hole is coaxially connected with the through-hole.

[0012] By adopting the above technical solution, the installation mechanism includes an installation plate with clearance holes to provide clearance space for the drill bit of the core drilling machine. The installation plate has an installation groove for inserting the water suction component. Since the water suction component and the installation groove are plugged into each other, it is convenient to replace the water suction component.

[0013] Therefore, by replacing the water suction component in the installation slot, the auxiliary device can operate continuously, which facilitates the auxiliary device in assisting the core drilling machine to carry out continuous core sampling operations.

[0014] Optionally, a sliding plate frame is provided between the water-absorbing component and the mounting plate. The sliding plate frame is sleeved on the outside of the water-absorbing component, and the water-absorbing component is detachably connected to the sliding plate frame. The sliding plate frame is inserted into the mounting groove, and the sliding plate frame is slidably connected to the inner wall of the mounting groove along the depth direction of the mounting groove.

[0015] By adopting the above technical solution, the sliding plate frame is used to install the water suction component. The sliding plate frame is inserted into the mounting groove and slides along the depth direction of the mounting groove to connect with the inner wall of the mounting groove. This makes it easy for the sliding plate frame to be pulled out of the mounting groove and also easy for the sliding plate frame to be inserted into the mounting groove. Therefore, the sliding plate frame facilitates the replacement of the water suction component.

[0016] Optionally, the sliding plate frame is provided with a plurality of magnetic attraction locking components, which are arranged around the water-absorbing component; the magnetic attraction locking components include a fixed magnetic strip and a movable magnetic block, the fixed magnetic strip is disposed on the sliding plate frame, the fixed magnetic strip and the movable magnetic block are spaced apart along the axial direction of the water-collecting cylinder, and the water-absorbing component is located between the fixed magnetic strip and the movable magnetic block, and the fixed magnetic strip and the movable magnetic block respectively abut against the side wall corresponding to the water-absorbing component.

[0017] By adopting the above technical solution, the magnetic clamping component includes a fixed magnetic strip and a movable magnetic block. Since the water-absorbing component is located between the fixed magnetic strip and the movable magnetic block, the water-absorbing component can be clamped and fixed by the cooperation of the fixed magnetic strip and the movable magnetic block, thereby enabling the detachable connection between the water-absorbing component and the sliding plate frame.

[0018] Optionally, a sealing plate is provided on one side of the sliding plate frame. When the sliding plate frame is inserted into the mounting groove, the sealing plate is inserted into the opening of the mounting groove and the sealing plate closes the opening of the mounting groove.

[0019] By adopting the above technical solution, the sealing plate is used to seal the installation groove when the sliding plate frame is inserted into the installation groove, which can prevent sewage from flowing out of the installation groove.

[0020] Optionally, it also includes a water absorption control mechanism, which includes a waterproof cylinder, a first cylinder, and a second cylinder; the first cylinder is inserted into the clearance hole, one axial end of the first cylinder is connected to the water-gathering cylinder, and the first cylinder and the water-gathering cylinder are coaxially connected; a first water guide hole is provided through the side wall of the first cylinder, and the first water guide hole is connected to the mounting groove; the waterproof cylinder is coaxially inserted into the water-gathering cylinder, and the waterproof cylinder is rotatably connected to the inner wall of the water-gathering cylinder; the second cylinder is coaxially inserted into the first cylinder, one axial end of the second cylinder is connected to the waterproof cylinder, and the second cylinder and the waterproof cylinder are coaxially connected; a second water guide hole is provided through the side wall of the second cylinder, and the first water guide hole is connected to the second water guide hole.

[0021] By adopting the above technical solution, since the first cylinder and the water-gathering cylinder are coaxially connected, the second cylinder and the waterproof cylinder are coaxially connected, and the waterproof cylinder and the water-gathering cylinder are rotatably connected, and the first cylinder and the second cylinder are rotatably connected, the second cylinder will also rotate inside the first cylinder when the waterproof cylinder is rotated.

[0022] Since the first cylinder has a first water guide hole and the second cylinder has a second water guide hole, and the first water guide hole, the second water guide hole and the mounting groove are connected, the sewage can enter the mounting groove through the second water guide hole and the first water guide hole in sequence, and then be absorbed by the water suction component.

[0023] Since the waterproof cylinder and the water-collecting cylinder can rotate relative to each other, and the first cylinder and the second cylinder can rotate relative to each other, by rotating the waterproof cylinder, the second cylinder can rotate relative to the first cylinder. This will allow the first water guide hole to be closed by the second cylinder, and at the same time the second water guide hole to be closed by the first cylinder. At this time, sewage cannot enter the installation groove, nor can it be absorbed by the water-absorbing component.

[0024] Based on the above principle, before core sampling, rotating the waterproof cylinder will close the first and second water guide holes. At this time, the water suction component will not absorb water, which will accelerate the rise of the sewage level in the water collection cylinder. As a result, when the drain tap is opened, more sewage can be discharged.

[0025] Furthermore, since the water-absorbing component does not absorb water at the beginning, its water storage performance and absorption speed can be maintained at their best. When the water-absorbing component needs to absorb the remaining sewage, the waterproof cylinder is rotated to connect the first and second water guide holes. At this time, the water-absorbing component can absorb water and quickly dry the remaining sewage, thus improving the sewage treatment speed.

[0026] Therefore, by setting up a water suction control mechanism, the operation of the water suction components can be controlled, which can increase the discharge volume of sewage and more thoroughly absorb the residual sewage, thereby further reducing the sewage removal effect and further reducing the sewage residue on the road surface.

[0027] Optionally, a limiting post is provided on the outer wall of the waterproof cylinder, and a guide elongated hole is provided through the side wall of the water-collecting cylinder. The length direction of the guide elongated hole is arranged along the circumference of the water-collecting cylinder. One end of the limiting post is connected to the outer wall of the waterproof cylinder, and the other end is inserted into the guide elongated hole. The limiting post is slidably connected to the inner wall of the guide elongated hole along the length direction of the guide elongated hole.

[0028] By adopting the above technical solution, the combination of the limiting post and the guide elongated hole can limit and guide the rotation angle between the waterproof cylinder and the water-gathering cylinder, preventing the rotation angle between the waterproof cylinder and the water-gathering cylinder from being too large or too small, which would result in the first water guide hole and the second water guide hole not being completely closed.

[0029] Optionally, a water outlet elongated hole is provided through the outer wall of the waterproof cylinder, the length direction of the water outlet elongated hole is arranged along the circumference of the waterproof cylinder, and the water outlet elongated hole is connected to the water inlet of the drain faucet.

[0030] By adopting the above technical solution, the setting of the water outlet elongated hole ensures that the drain faucet is always connected to the waterproof cylinder when the waterproof cylinder is high, so that sewage can be discharged through the drain faucet and drain pipe.

[0031] Optionally, the mounting plate has a connecting groove on the side facing the water collecting cylinder, and the connecting groove is coaxially arranged with the water suction hole; the water collecting cylinder is inserted into the connecting groove, and the water collecting cylinder is connected to the inner wall of the connecting groove by a thread.

[0032] By adopting the above technical solution, the opening of the connecting groove, and the connection between the inner wall of the connecting groove and the water collecting cylinder by thread, a detachable connection between the water collecting cylinder and the mounting plate is achieved.

[0033] Optionally, a waterproof pad is provided at the end of the mounting plate away from the water collection cylinder, and a through hole is provided through the waterproof pad, which communicates with the water absorption hole.

[0034] By adopting the above technical solution, the installation of waterproof pads can increase the sealing between the mounting plate and the road surface, reducing the possibility of sewage leakage.

[0035] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, through the installation of a water-absorbing component, can absorb the sewage remaining in the water-collecting cylinder, thereby reducing the sewage residue on the road surface and thus reducing sewage pollution to the road surface.

[0036] 2. The installation mechanism of this application facilitates the replacement of the water suction component, thereby facilitating continuous new operation of the auxiliary device.

[0037] 3. By setting up a water absorption control mechanism, this application can control the water absorption time of the water absorption component, thereby allowing for a larger discharge of sewage and a more thorough absorption of residual sewage. This further improves the sewage removal effect and reduces sewage residue on the road surface. Attached Figure Description

Detailed Implementation

[0046] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0047] Example 1: An auxiliary device for on-site core sampling and road surface cleaning, referring to... Figure 1 The system includes a water collection cylinder 1, which is vertically oriented. A drain faucet 2 is installed on the outer wall of the water collection cylinder 1. The inlet of the drain faucet 2 is connected to the water collection cylinder 1, and the outlet of the drain faucet 2 is connected to a drain pipe 3. The drain pipe 3 is threadedly connected to the drain faucet 2. This structural arrangement allows the water collection cylinder 1 to be fitted onto the outside of the drill bit of the core drilling machine. When the core drilling machine is working, cooling water collects inside the water collection cylinder 1, thus collecting wastewater. The drain faucet 2 and drain pipe 3 then discharge the wastewater from the water collection cylinder 1, achieving wastewater removal.

[0048] Reference Figure 2 A water-collecting cylinder 1 has a water-absorbing component 4 on its lower side. The water-absorbing component 4 is made of absorbent sponge, and a water-absorbing hole 41 is opened through one side along its thickness direction. The lower side of the water-collecting cylinder 1 abuts against the water-absorbing component 4, and the water-collecting cylinder 1 and the water-absorbing hole 41 are coaxially connected. Due to the height difference between the drain faucet 2 and the ground, some sewage may remain in the water-collecting cylinder 1 and cannot be discharged from the drain faucet 2. The water-absorbing component 4 can absorb this sewage, making the sewage removal more thorough.

[0049] In this embodiment, the inner diameter of the water-collecting cylinder 1 is 150mm, the wall thickness of the water-collecting cylinder 1 is 8mm, and the height difference between the lower end of the water-collecting cylinder 1 and the drain faucet 2 is 90mm. The corresponding water-absorbing component 4 has a thickness of 30mm to 150mm, preferably 100mm, and is a square shape with a length and width of 250mm. The inner diameter of the water-absorbing hole 41 is 120mm. This size setting can meet the actual requirements and reduce the residue of sewage.

[0050] The implementation principle of this application embodiment is as follows: When the core drilling machine is performing core sampling, the water collection cylinder 1 is fitted outside the drill bit. At this time, the water cooling the drill bit gathers inside the water collection cylinder 1, and the powder produced by the core drilling dissolves in the water, reducing the possibility of water seeping into the roadbed. Furthermore, the drill bit can be maintained in the sewage, extending its service life. After the core sampling is completed, the drain faucet 2 is opened, and the sewage in the water collection cylinder 1 is discharged into the corresponding container through the drain faucet 2 and the drain pipe 3, realizing the collection of sewage. After this, some sewage will remain at the bottom of the water collection cylinder 1, at which time the water suction component 4 will suck up the excess sewage.

[0051] Example 2: An auxiliary device for on-site core sampling and road surface cleaning, referring to... Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that an installation mechanism 5 is provided between the water collecting cylinder 1 and the water absorption component 4. Reference Figure 4 and Figure 5The mounting mechanism 5 includes a mounting plate 51. A clearance hole 511 is formed through one side of the mounting plate 51 in the thickness direction. A mounting groove 512 is formed on the side wall of the mounting plate 51, communicating with the clearance hole 511. A water-absorbing component 4 is disposed within the mounting groove 512. A water-absorbing hole 41 is coaxially connected to the clearance hole 511, and the inner diameter of the clearance hole 511 is not less than the inner diameter of the water-absorbing hole 41. The lower end of the water-collecting cylinder 1 is detachably connected to the mounting plate 51, and the water-collecting cylinder 1 communicates with the clearance hole 511. The structure of the mounting plate 51 enables the connection between the water-collecting cylinder 1 and the water-absorbing component 4.

[0052] Reference Figure 4 and Figure 5 The mounting plate 51 has a connecting groove 513 on the side facing the water collecting cylinder 1. The connecting groove 513 is coaxially arranged with the clearance hole 511. The water collecting cylinder 1 is inserted into the connecting groove 513, and the outer wall of the water collecting cylinder 1 and the inner wall of the connecting groove 513 are connected by threads. This structure enables a detachable connection between the mounting plate 51 and the water collecting cylinder 1, facilitating the independent replacement of the mounting plate 51 and the water collecting cylinder 1.

[0053] Reference Figure 4 and Figure 5 A waterproof pad 514 is provided on the side of the mounting plate 51 away from the water collection cylinder 1. The waterproof pad 514 is made of leather or rubber and is fixedly connected to the mounting plate 51 on its upper side. A through hole 5141 is provided through the waterproof pad 514, which is coaxially connected to the relief hole 511, and the inner diameter of the through hole 5141 is not less than the diameter of the relief hole 511. When using this auxiliary device, a heavy object can be placed on the upper side of the mounting plate 51 or pressure can be applied. At this time, the waterproof pad 514 is pressed tightly against the ground, which can improve the sealing between the mounting plate 51 and the ground and reduce the possibility of sewage leakage from the gap between the mounting plate 51 and the ground.

[0054] Reference Figure 4 and Figure 5 The mounting mechanism 5 also includes a sliding plate frame 52, which is inserted into the mounting groove 512 and slides along the depth direction of the mounting groove 512 to connect with the inner wall of the mounting groove 512, which facilitates the installation and disassembly of the sliding plate frame 52 and the mounting plate 51.

[0055] Reference Figure 4 and Figure 5 The sliding plate frame 52 is sleeved on the outside of the water-absorbing component 4, and the water-absorbing component 4 is slidably connected to the inner wall of the sliding plate frame 52 along the axial direction of the water-collecting cylinder 1. Because the water-absorbing component 4 is slidably connected to the inner wall of the sliding plate frame 52, the water-absorbing component 4 is easily removed from the sliding plate frame 52 and easily installed onto the sliding plate frame 52, thus facilitating the installation and removal of the water-absorbing component 4. Therefore, by replacing the water-absorbing component 4, the auxiliary device can be used continuously.

[0056] Reference Figure 4 and Figure 5 A sealing plate 521 is provided on the sliding plate frame 52. When the sliding plate frame 52 is inserted into the mounting groove 512, the sealing plate 521 is inserted into the opening of the mounting groove 512 and seals the opening of the mounting groove 512. The sealing plate 521 is used to seal the mounting groove 512 to prevent water in the water-absorbing component 4 from flowing out of the mounting groove 512 after water absorption, thereby preventing sewage leakage.

[0057] Reference Figure 5 and Figure 6 The sliding plate frame 52 is provided with a number of magnetic clamping components 53, which are arranged around the water-absorbing component 4.

[0058] Reference Figure 5 and Figure 6 The magnetic locking assembly 53 includes a fixed magnetic strip 531 and several movable magnetic blocks 532. The fixed magnetic strip 531 and the movable magnetic blocks 532 are arranged vertically at intervals. The several movable magnetic blocks 532 are arranged sequentially at intervals along the length of the fixed magnetic strip 531. The water-absorbing component 4 is located vertically between the movable magnetic blocks 532 and the fixed magnetic strip 531, and the fixed magnetic strip 531 abuts against the water-absorbing component 4 vertically. Both the fixed magnetic strip 531 and the movable magnetic blocks 532 are mounted on the sliding plate frame 52. The cooperation between the movable magnetic blocks 532 and the fixed magnetic strip 531 achieves the fixation of the water-absorbing component 4 through magnetic attraction.

[0059] Reference Figure 5 and Figure 6 The magnetic locking assembly 53 also includes a movable long plate 533, which is located vertically above the fixed magnetic strip 531. The length of the movable long plate 533 is aligned with the length of the fixed magnetic strip 531. Several movable magnetic blocks 532 are disposed on the side of the movable long plate 533 facing the fixed magnetic strip 531. The width of the movable long plate 533 is rotatably connected to the inner wall of the sliding plate frame 52. When installing the water-absorbing component 4, the water-absorbing component 4 is placed on the fixed magnetic strip 531, and then the movable long plate 533 is rotated. At this time, the movable magnetic blocks 532 on the movable long plate 533 press the water-absorbing component 4 under the attraction of the fixed magnetic strip 531. When disassembling the water-absorbing component 4, the movable long plate 533 is rotated directly to separate the movable magnetic blocks 532 from the water-absorbing component 4, making it easy to replace the water-absorbing component 4.

[0060] Reference Figure 5 and Figure 6A sliding elongated hole 5331 is provided through the movable long plate 533. The length direction of the sliding elongated hole 5331 is set along the length direction of the movable long plate 533. Several movable magnetic blocks 532 are all arranged in the sliding elongated hole 5331, and the movable magnetic blocks 532 are slidably connected to the inner wall of the sliding elongated hole 5331 along the length direction of the sliding elongated hole 5331. This makes it easy to adjust the position of each movable magnetic block 532, thereby facilitating the adjustment of the fixed position of the water absorption component 4 and ensuring the stability of the water absorption component 4.

[0061] Reference Figure 3 and Figure 4 A water absorption control mechanism 6 is also provided between the water collection cylinder 1 and the mounting plate 51.

[0062] Reference Figure 4 and Figure 7 The water absorption control mechanism 6 includes a waterproof cylinder 61, which is inserted into the water collection cylinder 1. The waterproof cylinder 61 and the water collection cylinder 1 are coaxially arranged, and the waterproof cylinder 61 is rotatably connected to the inner wall of the water collection cylinder 1 along its circumference. A water outlet elongated hole 611 is provided through the side wall of the waterproof cylinder 61, and the length direction of the water outlet elongated hole 611 is arranged along the circumference of the waterproof cylinder 61. The water outlet elongated hole is connected to the drain faucet 2. During the rotation of the waterproof cylinder 61, the water outlet elongated hole 611 is always connected to the drain faucet 2, thereby ensuring that the sewage in the waterproof cylinder 61 can be discharged from the drain faucet 2.

[0063] Reference Figure 4 and Figure 7 A first plate 62 is provided at the lower end of the water collecting cylinder 1. The first plate 62 is located inside the water collecting cylinder 1 and closes the lower opening of the water collecting cylinder 1. The lower side of the first plate 62 abuts against the bottom of the connecting groove 513 and the first plate 62 is rotatably connected to the bottom of the connecting groove 513. A first hole 621 is provided through the first plate 62 and communicates with the clearance hole 511.

[0064] Reference Figure 4 and Figure 7 A plurality of first water flow holes 622 are provided through the first plate 62, and the plurality of first water flow holes 622 are arranged sequentially at intervals along the circumference of the first hole 621.

[0065] Reference Figure 4 and Figure 5 The bottom of the connecting groove 513 is provided with several water inlet holes 5131, which are arranged sequentially at intervals along the circumference of the relief hole 511. The water inlet holes 5131 are connected to the mounting groove 512.

[0066] The water inlet hole 5131 is set in a one-to-one correspondence with the first water outlet hole 622, and the first water outlet hole 622 is connected to the corresponding water inlet hole 5131. The water entering the water collecting cylinder 1 will flow into the mounting groove 512 through the first water outlet hole 622 and the corresponding water inlet hole 5131, and then be absorbed by the water suction component 4.

[0067] Reference Figure 4 and Figure 7 A second plate 63 is provided at the lower end of the waterproof cylinder 61. The second plate 63 is located inside the waterproof cylinder 61 and closes the waterproof cylinder 61. The lower side of the second plate 63 abuts against the upper side of the first plate 62, and the second plate 63 is rotatably connected to the upper side of the first plate 62. A second hole 631 is provided through the second plate 63, and the first hole 621 and the second hole 631 are coaxially connected.

[0068] Reference Figure 4 and Figure 7 A plurality of second water flow holes 632 are provided through the second plate 63, and the plurality of second water flow holes 632 are arranged sequentially at intervals along the circumference of the second hole 631. The second water flow holes 632 and the first water flow holes 622 are arranged in a one-to-one correspondence, and the second water flow holes 632 are connected to the corresponding first water flow holes 622. During the process of rotating the waterproof cylinder 61, the area of ​​the second water flow hole 632 connected to the corresponding first water flow hole 622 gradually decreases until the first plate 62 closes all the second water flow holes 632, and at the same time the second plate 63 closes all the first water flow holes 622. At this time, the water in the water collection cylinder 1 cannot flow into the mounting groove 512, and therefore cannot be absorbed by the water absorption component 4.

[0069] Reference Figure 4 and Figure 7 The lower end of the water collection cylinder 1 is also provided with a first cylinder 64, which is inserted into the clearance hole 511. The upper end of the first cylinder 64 is fixedly connected to the first plate 62. The first cylinder 64 is coaxially connected with the first hole 621. Several first water guide holes 641 are opened through the outer wall of the first cylinder 64. The several first water guide holes 641 are arranged sequentially at intervals along the circumference of the first cylinder 64, and the first water guide holes 641 are connected to the mounting groove 512.

[0070] Reference Figure 4 and Figure 7 The lower end of the waterproof cylinder 61 is also provided with a second cylinder 65, which is inserted and matched with the first cylinder 64. The upper end of the second cylinder 65 is fixedly connected to the second plate 63. The second cylinder 65 is coaxially connected with the second hole 631. A number of second water guide holes 651 are opened through the outer wall of the second cylinder 65. The number of second water guide holes 651 are arranged sequentially and spaced apart along the circumference of the second cylinder 65. The second water guide holes 651 are arranged one-to-one with the first water guide holes 641. The second water guide holes 651 and the corresponding first water guide holes 641 are interconnected.

[0071] Reference Figure 4 and Figure 7 When the waterproof cylinder 61 rotates, the communication area between the second water guide hole 651 and the corresponding first water guide hole 641 gradually decreases until the first cylinder 64 closes all the second water guide holes 651, and at the same time the second cylinder 65 closes all the first water guide holes 641. At this time, the sewage in the clearance hole 511 cannot enter the installation groove 512 and cannot be absorbed by the water suction component 4.

[0072] Reference Figure 4 and Figure 7 Furthermore, during the rotation of the waterproof cylinder 61, when the first water guide hole 641 is connected to the corresponding second water guide hole 651, the first water outlet hole 622 is also connected to the corresponding second water outlet hole 632. At the same time, when all the second water guide holes 651 are closed by the first cylinder 64, all the second water outlet holes 632 are also closed by the first plate 62.

[0073] Reference Figure 3 and Figure 7 A rotation limiting assembly 66 is provided between the waterproof cylinder 61 and the water-collecting cylinder 1. The rotation limiting assembly 66 includes a limiting post 661, which is disposed on the outer wall of the waterproof cylinder 61. One end of the limiting post 661 is fixedly connected to the outer wall of the waterproof cylinder 61, and the other end extends toward the inner wall of the water-collecting cylinder 1. A guide elongated hole 662 is provided through the outer wall of the water-collecting cylinder 1. The length direction of the guide elongated hole 662 is arranged along the circumference of the water-collecting cylinder 1. The end of the limiting post 661 away from the waterproof cylinder 61 is inserted into the guide elongated hole 662, and the limiting post 661 is slidably connected to the inner wall of the guide elongated hole 662 along the length direction of the guide elongated hole 662.

[0074] Reference Figure 3 and Figure 7 When the waterproof cylinder 61 needs to be rotated, the limiting pin 661 slides within the guide hole 662, which enables the waterproof cylinder 61 to rotate and limits the angle of rotation. During the rotation of the waterproof cylinder 61, the auxiliary device has the following two working states: In the first working state, the first water guide hole 641 is connected to the corresponding second water guide hole 651, and the first water flow hole 622 is connected to the corresponding second water flow hole 632. At this time, the water suction component 4 can absorb sewage. In the second working state, all the first water guide holes 641, second water guide holes 651, first water flow holes 622, and second water flow holes 632 are closed. At this time, the water suction component 4 cannot absorb sewage.

[0075] The implementation principle of this application embodiment is as follows: the water collection cylinder 1 is installed at the corresponding position on the ground, and several heavy objects are placed on the upper side of the mounting plate 51 to ensure that the sealing between the mounting plate 51 and the ground meets the requirements.

[0076] Before the core drilling machine starts working, the waterproof cylinder 61 is rotated. At this time, all the second water guide holes 651 and the second water flow holes 632 are closed. The core drilling mechanism is started to work. Cooling water will gather in the water collection cylinder 1, and the water suction component 4 cannot suck up the sewage, which will cause the liquid level in the water collection cylinder 1 to rise rapidly.

[0077] After the core drilling machine finishes its work, or when the liquid level in the water collection cylinder 1 is too high, the drain faucet 2 is opened. At this time, the sewage in the water collection cylinder 1 will enter the corresponding sewage collection container through the drain faucet 2 and the drain pipe 3. When the liquid level drops below the drain faucet 2, the drain faucet 2 can no longer drain water. The waterproof cylinder 61 is rotated so that the first water guide hole 641 is connected to the corresponding second water guide hole 651, and the second water flow hole 632 is connected to the corresponding first water flow hole 622. At this time, the remaining water in the water collection cylinder 1 will be quickly sucked into the water suction component 4.

[0078] When the auxiliary device needs to operate continuously, it is only necessary to remove the water collection cylinder 1 and the waterproof cylinder 61 from the mounting plate 51 after each operation, and then the water absorption component 4 of the mounting plate 51 can be replaced, which allows the auxiliary device to be ready for the next operation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
