Description

Technical Field

[0001] This utility model relates to the field of hydropower installation equipment technology, specifically a hydropower installation trenching device. Background Technology

[0002] During plumbing and electrical installations, grooves need to be cut into walls to pre-embed pipes and wires. Previously, single-blade cutting machines were used to cut the walls. While this allowed for width control, it required multiple cuts, resulting in low efficiency. With technological advancements, multi-blade grooving machines have become increasingly common, significantly improving grooving efficiency.

[0003] Utility model patent CN222904518U discloses a grooving machine for water and electricity installation in interior decoration. The machine includes a body with a handle rotatably connected to its surface. A saw blade is installed inside the body. A cleaning device is provided on the surface of the body, including a connecting frame rotatably connected to the surface of the body. A protective cover is fixedly connected to one side of the connecting frame, and a guide block is fixedly connected to the inner wall of the protective cover. An auxiliary device is provided on the surface of the body, and the longitudinal section of the guide block is a combination of multiple triangles. A spring is fixedly connected to one side of the protective cover, and the end of the spring away from the protective cover is fixedly connected to the surface of the body. The cleaning device facilitates dust removal, reduces dust splashing, lowers the probability of users inhaling dust, improves operational safety, and facilitates the normal use of the equipment.

[0004] The aforementioned patent provides a grooving machine that can mainly handle dust. Although it can improve the working environment, the existing multi-blade grooving machine still has obvious defects: if the grooving width needs to be adjusted, the entire cutting component must be replaced. This is not only cumbersome to operate, but also requires the preparation of multiple sets of cutting components of different specifications, resulting in a significant increase in operating costs.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0026] Example 1

[0027] like Figure 1 and Figure 3As shown, a hydroelectric installation trenching device includes a drive motor set 1, which is the power source of the device and is used to drive the trenching device to rotate. The output end of the drive motor unit 1 is equipped with a cutting blade guard 3. The inner side of the cutting blade guard 3 is rotatably connected to the cutting assembly 2. The cutting assembly 2 is rotatably connected to the cutting blade guard 3, and at the same time undertakes the dual functions of protection and power transmission, preventing cement and brick fragments generated during cutting from flying and protecting the safety of operators; at the same time, it avoids damage to the cutting blade 9 from external collisions. The output end of the drive motor unit 1 is connected to the cutting assembly 2 to drive the cutting assembly 2 to rotate. The cutting assembly 2 includes multiple cutting blades 9, a flower rod shaft 10, and multiple spacer sleeves 13. Multiple cutting blades 9 are sleeved on the flower rod shaft 10. Spacer sleeves 13 are provided between adjacent cutting blades 9 and between the two ends of the cutting blades 9 and the flower rod shaft 10. The distance between the cutting blades 9 can be adjusted by increasing or decreasing the number of spacer sleeves 13 between adjacent cutting blades 9. The cutting blades 9 can also be increased or decreased, so that the entire grooving equipment can flexibly adjust the clamp between two cutting blades 9 according to the cutting requirements, or increase or decrease the cutting blades 9 according to the cutting requirements.

[0028] like Figure 1 As shown, the drive motor unit 1 is equipped with handles on both its side and one end face. The handle on the side of the drive motor unit 1 is connected to its rotation. The handles are designed to facilitate gripping of the drive motor unit 1, thereby making it easier for workers to operate the entire grooving equipment to groove the wall.

[0029] like Figure 2 As shown, the cutting disc guard 3 comprises an outer guard 5, a motor drive assembly 6, and guard side plates 7. The guard side plates 7 are located at an opening on one side of the outer guard 5, and the motor drive assembly is located on the other side of the outer guard 5. The output end of the drive motor 1 is connected to the motor drive assembly 6, which in turn drives the flower rod shaft 10 to rotate. The main frame of the outer guard 5, which encloses the cutting disc 9 and the spacer sleeve 13, is the main structure for fragment protection, and the guard side plates 7 provide lateral support. The central shaft-perforated bearing 8 provides a rotation fulcrum for the flower rod shaft 10 of the cutting disc 9, reducing friction during shaft rotation. The guard side plates 7 have a central shaft-perforated bearing 8. One end of the flower rod shaft 10 passes through the shaft-perforated bearing 8 and is connected to the motor drive assembly 6, while the other end of the flower rod shaft 10 is interference-fitted to the shaft-perforated bearing 8. The shaft-perforated bearing 8 reduces the rotational resistance of the shaft, ensuring smooth rotation of the cutting disc 9 and preventing vibration from affecting the grooving accuracy.

[0030] like Figure 3As shown, the motor transmission assembly 6 includes a drive shaft 14, bevel gear sets 15, and reverse threaded sleeves 16. Two sets of bevel gear sets 15 are respectively located on the side of the reverse threaded sleeve 16 and the bottom of the drive shaft 14. The reverse threaded sleeve 16 is used to connect to the flower rod shaft 10, thereby converting the power transmitted by the bevel gear sets 15 into the rotational power of the cutting blades 9. The two sets of bevel gear sets 15 are meshed, changing the direction of power transmission (converting the longitudinal rotation of the drive shaft 14 into the transverse rotation of the reverse threaded sleeve 16), adapting to the transverse installation requirements of the cutting blades 9. The top end of the drive shaft 14 is connected to the drive motor assembly 1, receiving the motor power and transmitting it downwards.

[0031] like Figure 3 As shown, the flower stem shaft 10 has a side end shank 11 facing outwards at one end and a reverse thread stud 12 at the other end. The flower stem shaft 10 is integrally fixed with the side end shank 11 and the reverse thread stud 12. The reverse thread stud 12 is used to connect with a reverse thread nut, thus facilitating the use of the flower stem shaft 10 with a reverse thread sleeve 16. The reverse thread stud 12 is threadedly connected to the reverse thread sleeve 16. The flower stem shaft 10 has symmetrical keyways on its side. The keyways are used to engage with the spacer sleeve 13 and the cutting blade 9, preventing relative rotation between the spacer sleeve 13 and the cutting blade 9 and the flower stem shaft 10. The spacer sleeve 13 has a sleeve hole in the middle. A protrusion is provided on the inner side of the sleeve hole, aligned with the keyway. The protrusion engages with the inner side of the keyway, preventing relative rotation between the spacer sleeve 13 and the flower stem shaft 10. The cutting blade 9 has a through hole in the middle. A protrusion is provided on the inner side of the through hole. The protrusion engages with the inner side of the keyway, preventing relative rotation between the cutting blade 9 and the flower stem shaft 10.

The cutting assembly 2 is rotatably connected to the cutting blade guard 3, and at the same time undertakes the dual functions of protection and power transmission, preventing cement and brick fragments generated during cutting from flying and protecting the safety of operators; at the same time, it avoids damage to the cutting blade 9 from external collisions. The output end of the drive motor unit 1 is connected to the cutting assembly 2 to drive the cutting assembly 2 to rotate. The cutting assembly 2 includes multiple cutting blades 9, a flower rod shaft 10, and multiple spacer sleeves 13. Multiple cutting blades 9 are sleeved on the flower rod shaft 10. Spacer sleeves 13 are provided between adjacent cutting blades 9 and between the two ends of the cutting blades 9 and the flower rod shaft 10. The distance between the cutting blades 9 can be adjusted by increasing or decreasing the number of spacer sleeves 13 between adjacent cutting blades 9. The cutting blades 9 can also be increased or decreased, so that the entire grooving equipment can flexibly adjust the clamp between two cutting blades 9 according to the cutting requirements, or increase or decrease the cutting blades 9 according to the cutting requirements.

[0034] like Figure 1 As shown, the drive motor unit 1 is equipped with handles on both its side and one end face. The handle on the side of the drive motor unit 1 is connected to its rotation.

The guard side plates 7 are located at an opening on one side of the outer guard 5, and the motor drive assembly is located on the other side of the outer guard 5. The output end of the drive motor 1 is connected to the motor drive assembly 6, which in turn drives the flower rod shaft 10 to rotate. The main frame of the outer guard 5, which encloses the cutting disc 9 and the spacer sleeve 13, is the main structure for fragment protection, and the guard side plates 7 provide lateral support. The central shaft-perforated bearing 8 provides a rotation fulcrum for the flower rod shaft 10 of the cutting disc 9, reducing friction during shaft rotation. The guard side plates 7 have a central shaft-perforated bearing 8. One end of the flower rod shaft 10 passes through the shaft-perforated bearing 8 and is connected to the motor drive assembly 6, while the other end of the flower rod shaft 10 is interference-fitted to the shaft-perforated bearing 8. The shaft-perforated bearing 8 reduces the rotational resistance of the shaft, ensuring smooth rotation of the cutting disc 9 and preventing vibration from affecting the grooving accuracy.

[0036] like Figure 3 As shown, the motor transmission assembly 6 includes a drive shaft 14, bevel gear sets 15, and reverse threaded sleeves 16. Two sets of bevel gear sets 15 are respectively located on the side of the reverse threaded sleeve 16 and the bottom of the drive shaft 14. The reverse threaded sleeve 16 is used to connect to the flower rod shaft 10, thereby converting the power transmitted by the bevel gear sets 15 into the rotational power of the cutting blades 9. The two sets of bevel gear sets 15 are meshed, changing the direction of power transmission (converting the longitudinal rotation of the drive shaft 14 into the transverse rotation of the reverse threaded sleeve 16), adapting to the transverse installation requirements of the cutting blades 9. The top end of the drive shaft 14 is connected to the drive motor assembly 1, receiving the motor power and transmitting it downwards.

[0037] like Figure 3As shown, the flower stem shaft 10 has a side end shank 11 facing outwards at one end and a reverse thread stud 12 at the other end. The flower stem shaft 10 is integrally fixed with the side end shank 11 and the reverse thread stud 12. The reverse thread stud 12 is used to connect with a reverse thread nut, thus facilitating the use of the flower stem shaft 10 with a reverse thread sleeve 16. The reverse thread stud 12 is threadedly connected to the reverse thread sleeve 16. The flower stem shaft 10 has symmetrical keyways on its side. The keyways are used to engage with the spacer sleeve 13 and the cutting blade 9, preventing relative rotation between the spacer sleeve 13 and the cutting blade 9 and the flower stem shaft 10. The spacer sleeve 13 has a sleeve hole in the middle. A protrusion is provided on the inner side of the sleeve hole, aligned with the keyway. The protrusion engages with the inner side of the keyway, preventing relative rotation between the spacer sleeve 13 and the flower stem shaft 10. The cutting blade 9 has a through hole in the middle. A protrusion is provided on the inner side of the through hole. The protrusion engages with the inner side of the keyway, preventing relative rotation between the cutting blade 9 and the flower stem shaft 10.

[0038] like Figure 1 As shown, an inclined guide plate 4 is provided on the side of the drive motor unit 1 at the position aligned with the opening of the cutting sheet guard tile 3. The inclined guide plate 4 is used to guide the grooving direction and angle.

[0039] Working principle: The drive motor unit 1 serves as the power source for the equipment. Its output end connects to the motor unit transmission assembly 6 to transmit power, and also provides protection and support through the cutting blade guard 3. In the motor unit transmission assembly 6, the transmission shaft 14 receives the power from the drive motor unit 1 and transmits it downwards. Two sets of meshing bevel gears 15 convert the longitudinal rotation of the transmission shaft 14 into the lateral rotation of the reverse threaded sleeve 16. The reverse threaded sleeve 16 is then threadedly connected to the reverse threaded stud 12 at one end of the flower rod shaft 10, driving the flower rod shaft 10 to rotate synchronously. The flower rod shaft 10 is fitted with a cutting blade 9 and a spacer sleeve 13. The keyway on the side of the flower rod shaft 10 engages with the protrusion on the inner side of the spacer sleeve 13's hole and the protrusion on the inner side of the cutting blade 9's through hole, effectively preventing relative rotation between the spacer sleeve 13, the cutting blade 9, and the flower rod shaft 10, thus ensuring the flower rod... The shaft 10 can stably drive the cutting blade 9 to rotate to complete the wall grooving. The spacing between the cutting blades 9 can be adjusted by increasing or decreasing the number of spacer sleeves 13 between adjacent cutting blades 9, or the cutting blades 9 can be directly added or removed to adapt to different grooving requirements. The outer protective tile 5 of the cutting blade protective tile 3 wraps around the cutting blade 9 and the spacer sleeves 13 to prevent cement and brick fragments from splashing during cutting and to avoid damage to the cutting blade 9 from external collisions. The side plate 7 of the protective tile provides lateral support, and the shaft through bearing 8 in its center can also provide a rotation fulcrum for the flower rod shaft 10 to reduce rotational friction, ensure the smooth rotation of the cutting blade 9 and improve the grooving accuracy. At the same time, the handles on the side and one end of the drive motor unit 1 make it convenient for workers to hold and operate the equipment. The inclined guide plate 4 aligned with the opening of the cutting blade protective tile 3 on the side can guide the grooving direction and angle, ensuring that the entire grooving process is stable and controllable.

[0040] In summary, compared with the prior art, this application optimizes the setting of the wall grooving equipment, changes the inconvenience of the traditional single cutting blade 9 and the cumbersome replacement and width adjustment of multiple cutting blades 9, and designs a cutting equipment that reduces accessories and is easy to replace. It reduces costs while allowing for arbitrary adjustment of the width setting, and is suitable for widespread use.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
