[0010] Through the technical scheme, when the grooving machine grooves the wall surface, the staff holds the water and electricity grooving machine to groove, but long-time holding of the grooving machine increases the burden of the staff's hands and gradually becomes powerless, so that the stability of the grooving work cannot be guaranteed, and then the crawling guide wheel is abutted against the surface of the wall body, the staff can push the grooving machine forward, so that the burden of the staff holding the grooving machine can be reduced, in order to facilitate the staff to push the grooving machine forward to groove, a straight plate is fixed on the grooving surface, and then the outer surface of the positioning guide wheel is in contact with the surface of the plate, so that when the grooving machine moves, the positioning guide wheel moves on the surface of the plate, and the guiding during the grooving machine work is realized.

[0011] Preferably, the side surface of the support frame body away from the wall body is fixedly connected with a transverse fixed handle, and the surface is further hingedly connected with a vertical movable movable handle.

[0012] Through the technical scheme, in order to facilitate the staff to hold the grooving machine, one hand holds the fixed handle to stabilize the grooving machine, and the other hand can adjust the holding angle according to the use habit to hold the movable handle, so that the staff can conveniently groove.

[0014] Through the technical scheme, in order to control the rotation of the grooving blade to groove, the self-locking pipe is driven to rotate by the grooving motor, so that the grooving blade is driven to rotate to realize the grooving action, and the pawl is arranged in the inside of the self-locking pipe, so that the locking of the grooving blade can be realized when the self-locking pipe is locked.

[0015] Preferably, the self-locking mechanism further comprises a support shaft fixedly connected to the inner surface of the grooving machine shell, a free end of the support shaft extends to the inside of the self-locking pipe and is rotatably connected thereto, the inner surface of the self-locking pipe is annularly arranged and distributed with ratchet grooves, and the outer surface of the pawl is slidably connected with the inner surface of the ratchet groove.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figures 1-8 A grooving machine for water and electricity renovation includes a support frame 1, a grooving machine housing 2 fixedly connected to the inner surface of the support frame 1, a guide wheel mechanism provided on the outer surface of the support frame 1, a grooving blade 3 rotatably connected to the side surface of the grooving machine housing 2 near the wall, and a self-locking mechanism provided on the inner surface of the grooving machine housing 2.

[0035] The guide wheel mechanism includes crawling guide wheels 4 that are symmetrically distributed and rotatably connected to both sides of the support frame 1. The outer surface of the crawling guide wheel 4 is provided with resistance blocks, so that when the crawling guide wheel 4 contacts the wall, it can guide the movement of the grooving machine and reduce the burden on the workers holding the grooving machine.

[0036] Currently, when grooving walls, workers hold the grooving machine by hand. However, prolonged handheld operation increases the burden on the workers' hands, gradually leading to weakness and making it difficult to ensure stable grooving. By using the crawling guide wheel 4 to press against the wall surface, workers can push the grooving machine forward, thus reducing the burden on the workers. To facilitate the workers pushing the grooving machine forward, the guide wheel mechanism also includes a positioning guide wheel 6 that is parallel to the side surface of the support frame 1 closest to the wall and is rotatably connected. A straight plate is placed and fixed on the grooving surface, and then the outer surface of the positioning guide wheel 6 contacts the surface of the plate. Thus, when the grooving machine moves, the positioning guide wheel 6 moves on the surface of the plate, achieving guidance during the operation of the grooving machine.

[0037] To facilitate workers' access to the grooving machine, a horizontal fixed handle 7 is fixedly connected to the side of the support frame 1 away from the wall. A vertical movable handle 8 is also hinged to the surface of the support frame 1 via a hinge. Workers can hold the fixed handle 7 with one hand to stabilize the grooving machine, and can adjust the holding angle of the other hand to hold the movable handle 8 according to their usage habits, thus facilitating workers' grooving work.

[0038] By setting up a guide wheel mechanism, the hand force of the operator holding the grooving machine can be distributed. During the adjustment process, the operator can push the grooving machine forward by having the crawling guide wheel 4 press against the surface of the wall, thus reducing the burden on the operator holding the grooving machine. At the same time, when the grooving machine moves, the positioning guide wheel 6 moves on the surface of the board to guide the grooving machine during operation, which can avoid the operator having to use their strength to find the correct grooving direction.

[0039] The self-locking mechanism includes a pawl 5, which controls the grooving blade 3 to rotate in one direction and locks it when it is not rotating.

[0040] In order to control the rotation of the grooving blade 3 to perform the grooving work, the self-locking mechanism also includes a grooving motor 9 fixedly connected to one side surface of the grooving machine housing 2. The output shaft of the grooving motor 9 extends to the outer surface inside the grooving machine and is fixedly connected to a self-locking tube 10. The grooving blade 3 is fixedly sleeved on the outer surface of the self-locking tube 10. The rotation of the grooving motor 9 drives the self-locking tube 10 to rotate, thereby driving the grooving blade 3 to rotate and realize the grooving action. The pawl 5 is set inside the self-locking tube 10, so that the grooving blade 3 can be locked when the self-locking tube 10 is locked.

[0041] To prevent the grooving blade 3 from slipping during clockwise movement, resulting in inconsistent grooving depths, the self-locking mechanism also includes a support shaft 11 fixedly connected to the inner surface of the grooving machine housing 2. The free end of the support shaft 11 extends into the self-locking tube 10 and is rotatably connected to it. The inner surface of the self-locking tube 10 has ratchet grooves 12 arranged in a ring array. The outer surface of the pawl 5 slides and engages with the inner surface of the ratchet groove 12, controlling the grooving blade 3 to rotate in one direction. That is, when the grooving blade 3 rotates counterclockwise, the pawl 5 will engage with the ratchet groove 12, preventing the grooving blade 3 from continuing to rotate counterclockwise. In this way, the self-locking tube 10 with the grooving blade 3 and the pawl 5 form a locked state, realizing unidirectional transmission, thereby preventing the gear from slipping when rotating clockwise and ensuring the stability of the transmission system.

[0042] To achieve the self-locking effect of the pawl 5, a mounting block 13 is fixedly sleeved on the outer surface of the support shaft 11. The outer surface of the mounting block 13 has notches 14 distributed diagonally symmetrically. The outer surface of the pawl 5 is hinged to the surface of the notch 14. A deformation spring 15 is fixedly connected to one side surface of the notch 14. The free end of the deformation spring 15 is fixedly connected to one side surface of the pawl 5. One end of the pawl 5 is hinged to the notch 14 of the mounting block 13. When the pawl 5 is rotated clockwise, the deformation spring 15 is compressed, which ensures the rotation of the slotted blade 3. When the pawl 5 is rotated counterclockwise, the deformation spring 15 is reset, pushing one end of the pawl 5 into the ratchet groove 12 to achieve self-locking.

[0043] To prevent dust generated during the operation of the grooving machine from affecting the operator's vision, conical guide hoods 16 are symmetrically distributed and fixedly connected to the side surface of the grooving machine housing 2 near the wall. A waste discharge pipe 17 is fixedly connected to the tail end of the grooving machine housing 2. Conical guide hoods 16 are set on both sides of the grooving blade 3 to guide the generated dust to the interior of the grooving machine housing 2 and guide it to the waste discharge pipe 17 through airflow, thereby discharging it to the outside. In order to reduce the resistance of the grooving machine's movement, a brush roller 18 is installed on the front side surface of the grooving machine housing 2 near the wall. A rolling brush roller 18 is set at the front end of the grooving machine housing 2 so that it rolls with the crawling roller and cleans the protruding particles on the wall surface.

[0044] By setting a self-locking mechanism, the stability of the grooving machine's transmission system can be maintained. During the adjustment process, when the grooving blade 3 rotates counterclockwise, the pawl 5 will engage with the ratchet groove 12, preventing the grooving blade 3 from continuing to rotate counterclockwise. In this way, the self-locking tube 10 with the grooving blade 3 and the pawl 5 form a locked state, realizing unidirectional transmission. This can prevent the gear from slipping when rotating clockwise, thus ensuring the stability of the transmission system.

[0045] Working principle: In a specific embodiment of this utility model, the operator can hold the fixed handle 7 with one hand to stabilize the grooving machine, and the other hand can adjust the holding angle according to the user's habits to hold the movable handle 8. Then, the grooving machine is brought close to the wall so that the crawling guide wheel 4 is against the surface of the wall. The operator can push the grooving machine forward. When the crawling guide wheel 4 rotates, the brush roller 18 rotates, and at the same time, it sweeps the protruding particles on the wall surface.

[0046] During grooving, a straight plate is placed and fixed on the grooving surface, and then the outer surface of the positioning guide wheel 6 is made to contact the surface of the plate. Thus, when the grooving machine moves, the positioning guide wheel 6 moves on the surface of the plate to guide the grooving machine during operation.

[0047] When the grooving machine moves, the grooving motor 9 rotates, driving the self-locking tube 10 to rotate, which in turn drives the grooving blade 3 to rotate clockwise, thus achieving the grooving action. When the grooving blade 3 rotates clockwise, it compresses the deformation spring 15, which ensures the rotation of the grooving blade 3. When it rotates counterclockwise, the deformation spring 15 returns to its original position, pushing one end of the pawl 5 into the ratchet groove 12. At this time, the pawl 5 will engage with the ratchet groove 12, preventing the grooving blade 3 from continuing to rotate counterclockwise. In this way, the self-locking tube 10 with the grooving blade 3 and the pawl 5 form a locked state, realizing unidirectional transmission, which can prevent the gear from slipping when rotating clockwise and ensure the stability of the transmission system.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
