[0020] like Figure 1 As shown, combined with Figure 2-4 As shown, the utility model is used for the grooving device of hydropower installation, including a base, on which a turntable 5 is rotatably mounted, and the base is provided with a limiting mechanism capable of clamping and releasing the turntable 5, and the turntable 5 is fixedly connected with a support rod 16 arranged along the radial direction of the turntable 5, and a tool holder is axially slidably mounted on the support rod 16, and a cutter 14 is rotatably mounted on the tool holder.

[0021] When the utility model is used for the grooving device for water and electricity installation, the route to be cut is marked on the wall where the groove is to be cut by means of a spring line. After the marking is completed, the base is placed at a suitable position near the route to be cut and fixed, the limit mechanism is adjusted to release the turntable 5, and then the turntable 5 is rotated to adjust the angle of the support rod 16 so that the axis of the support rod 16 is parallel to the marked route, and then the turntable 5 is clamped by adjusting the limit mechanism to prevent the turntable 5 from rotating, and then the cutter 14 is started to rotate, and then the knife holder is allowed to slide along the support rod 16, so that the knife holder drives the cutter 14 to groove the wall along the marked route, which can avoid errors in the groove.

[0022] When rotating the turntable 5, the operator can operate the support rod 16 to rotate. Since the support rod 16 is fixedly connected to the turntable 5, the turntable 5 can rotate, and the angle of the support rod 16 can also be adjusted.

[0023] like Figure 1 , 2 As shown in Figure 3, the utility model is a grooving device for water and electricity installation, wherein the base includes a bottom plate 1 and two fixed plates 3, the two fixed plates 3 are oppositely and fixedly arranged on the upper side of the bottom plate 1 at an interval, the two fixed plates 3 are both semicircular and are arranged perpendicular to the bottom plate 1, and the turntable 5 is rotatably installed between the two fixed plates 3 via a rotating shaft 2.

[0024] There are two specific ways to rotatably install the turntable 5 between the two fixed plates 3 via the rotating shaft 2: (1) Both fixed plates 3 are provided with shaft holes, and the two ends of the rotating shaft 2 are respectively fixed in the shaft holes of the two fixed plates 3, and the turntable 5 is rotatably installed on the rotating shaft 2 (the turntable 5 is rotatably installed on the rotating shaft 2 via a bearing, or the turntable 5 is sleeved on the rotating shaft 2 via a through hole on itself, and a clearance fit is made between the rotating shaft 2 and the through hole). In this way, the turntable 5 is rotatably installed between the two fixed plates 3 via the rotating shaft 2. (2) Both fixed plates 3 are provided with shaft holes, and the two ends of the rotating shaft 2 are respectively rotatably installed in the shaft holes of the two fixed plates 3 (the two ends of the rotating shaft 2 are respectively rotatably installed in the two shaft holes via a bearing, or a clearance fit is made between the rotating shaft 2 and the two shaft holes). The turntable 5 is fixedly sleeved on the rotating shaft 2. In this way, the turntable 5 is rotatably installed between the two fixed plates 3 via the rotating shaft 2.

[0025] like Figure 1 , 2As shown in Figure 3, the utility model is a grooving device for water and electricity installation, wherein the limiting mechanism includes a bidirectional threaded rod 9 and two clamping blocks 6, the bidirectional threaded rod 9 is rotatably mounted on the base plate 1, and the two ends of the bidirectional threaded rod 9 are respectively provided with a first thread and a second thread with opposite rotation directions, the two clamping blocks 6 are respectively threadedly connected to the first thread and the second thread, and the two clamping blocks 6 are both slidably mounted on the base plate 1 along the axial direction of the bidirectional threaded rod 9, the two clamping blocks 6 are located between the two fixed plates 3 and are respectively located on the opposite sides of the turntable 5, and when the bidirectional threaded rod 9 rotates, the two clamping blocks 6 can move towards each other to clamp the turntable 5 or move away from each other to release the turntable 5.

[0026] The utility model is used for a grooving device for hydropower installation, wherein a first slide groove 7 in the form of a strip is opened on the upper side surface of the base plate 1, the cross section of the first slide groove 7 is T-shaped, the first slide groove 7 is located between two fixed plates 3, a bidirectional threaded rod 9 is rotatably installed in the first slide groove 7 through a bearing seat, the bidirectional threaded rod 9 is arranged along the length direction of the first slide groove 7, that is, the axial direction of the bidirectional threaded rod 9 is consistent with the length direction of the first slide groove 7, two T-shaped sliding blocks 18 are slidably arranged in the first slide groove 7, the two T-shaped sliding blocks 18 are respectively threadedly connected to the first thread and the second thread of the bidirectional threaded rod 9, and one clamping block 6 is fixedly provided on each of the two T-shaped sliding blocks 18.

[0027] The two T-shaped sliders 18 are both slidably mounted on the first slide groove 7 of the bottom plate 1, and the length direction of the first slide groove 7 is consistent with the arrangement direction of the bidirectional threaded rod 9, and a clamping block 6 is fixedly mounted on each T-shaped slider 18, so it can be said that the two clamping blocks 6 are respectively slidably mounted on the bottom plate 1 along the axial direction of the bidirectional threaded rod 9 through the T-shaped slider 18. The two T-shaped sliders 18 are respectively threadedly connected to the first thread and the second thread of the bidirectional threaded rod 9, so it can also be said that the two clamping blocks 6 are respectively threadedly connected to the first thread and the second thread of the bidirectional threaded rod 9 through the T-shaped slider 18.

[0028] When the bidirectional threaded rod 9 is rotated, since the T-shaped slider 18 is slidably arranged on the T-shaped slide groove, the T-shaped slider 18 will not rotate with the bidirectional threaded rod 9. Since the two T-shaped sliders 18 are respectively threadedly connected to the first thread and the second thread of the bidirectional threaded rod 9 with opposite rotation directions, the two T-shaped sliders 18 can only slide towards or away from each other along the first slide groove 7 (i.e., the axial direction of the bidirectional threaded rod 9). When the two T-shaped sliders 18 slide towards each other, the two clamping blocks 6 simultaneously move towards each other until the turntable 5 is clamped, and the turntable 5 can no longer rotate; and when the two T-shaped sliders 18 slide away from each other, the two clamping blocks 6 simultaneously move away from each other and can release the turntable 5, and the turntable 5 can rotate. In this way, the above-mentioned two clamping blocks 6 can move towards each other to clamp the turntable 5 or move away from each other to release the turntable 5 when the bidirectional threaded rod 9 rotates can be achieved.

[0029] like Figure 2 As shown, the utility model is used for a grooving device for water and electricity installation, wherein the clamping surfaces of the two clamping blocks 6 are both arc-shaped surfaces matching the rim of the turntable 5. When the two clamping blocks 6 clamp the turntable 5, the two clamping blocks 6 abut against the two opposite rims of the turntable 5 through their respective clamping surfaces.

[0030] In order to increase the friction between the clamping block 6 and the turntable 5, a rubber pad 19 is fixedly provided on the clamping surface of the two clamping blocks 6, so that the clamping is more stable.

[0031] In order to facilitate the operator to rotate the bidirectional threaded rod 9, one end of the bidirectional threaded rod 9 is extended to the outside of the bottom plate 1 and fixedly connected to a rotating handle 8. The rotating handle 8 is in the shape of a circular plate, and the center of the rotating handle 8 is fixedly connected to the end of the bidirectional threaded rod 9 extending to the outside of the bottom plate 1, so that the operator only needs to rotate the rotating handle 8 to rotate the bidirectional threaded rod 9.

[0032] like Figure 1 , 2 As shown in FIG. 4 , the utility model is a grooving device for water and electricity installation, wherein a connecting seat 4 is fixedly provided on the wheel rim of the rotating disk 5, a threaded hole 21 is provided on the connecting seat 4, a threaded column 20 is fixedly provided on one end of the supporting rod 16, and the threaded column 20 is threadedly connected in the threaded hole 21. In this way, when the supporting rod 16 needs to be connected to the rotating disk 5, it is only necessary to rotate the threaded column 20 and connect it in the threaded hole 21 of the connecting seat 4. Conversely, the threaded column 20 is rotated in the opposite direction. When the threaded column 20 is disengaged from the threaded hole 21 of the connecting seat 4, the supporting rod 16 is also removed from the rotating disk 5.

[0033] When the utility model is in use, several more support rods 16 can be prepared, and one end of each support rod 16 is fixedly provided with a threaded column 20, and the other end surface of each support rod 16 is provided with a threaded blind hole 17 matching the threaded column 20. First, the first support rod 16 is connected to the threaded hole 21 of the connecting seat 4 through its own threaded column 20. When the length of the first support rod 16 is not enough, the threaded column 20 of the second support rod 16 can be connected to the threaded blind hole 17 of the first support rod 16. If it is still not enough, the threaded column 20 of the third support rod 16 can be connected to the threaded blind hole 17 of the second support rod 16, and so on, until the length of the support rod 16 meets the use requirements.

[0034] like Figure 1 , 2 As shown, the utility model is used for a grooving device for water and electricity installation, wherein the tool holder includes a fixedly connected mounting block 11 and a U-shaped frame 12, wherein the mounting block 11 is slidably mounted on the support rod 16 along the axial direction of the support rod 16, and a cutter 14 is rotatably mounted between the U-shaped frame 12, and the cutter 14 is disc-shaped, so that the axis of the cutter 14 is arranged perpendicular to the support rod 16. The cutter 14 is driven to rotate by a motor 13, and the motor 13 is fixedly mounted on the U-shaped frame 12. In order to facilitate the operator to pull the mounting block 11 to slide along the support rod 16, a handle 10 is fixedly provided on the mounting block 11.

[0035] The specific method of sliding the mounting block 11 on the support rod 16 along the axial direction of the support rod 16 is as follows: a plurality of limit rods 15 are fixedly provided on the outer peripheral wall of the support rod 16, and the plurality of limit rods 15 are arranged along the axial direction of the support rod 16; a sliding hole is provided on the mounting block 11, and a plurality of second sliding grooves are provided on the inner hole wall of the sliding hole, and the plurality of second sliding grooves are arranged along the axial direction of the sliding hole; the plurality of second sliding grooves are arranged one by one with the plurality of limit rods 15; the mounting block 11 is slidingly mounted on the support rod 16 through the sliding hole, and the plurality of limit rods 15 are respectively located in the second sliding grooves corresponding to each other. In this way, the mounting block 11 can only slide along the axial direction of the support rod 16, and cannot rotate relative to the support rod 16, so the mounting block 11 can drive the cutter 14 to move along the axial direction of the support rod 16, and because the axis of the support rod 16 is parallel to the marked route on the wall, the cutter 14 can cut and groove along the marked route without cutting crookedly.

[0036] In addition to the above-mentioned method of installing the mounting block 11 on the support rod 16 by sliding along the axial direction of the support rod 16, the mounting block 11 can also be installed on the support rod 16 by sliding along the axial direction of the support rod 16 in the following manner: a plurality of second slide grooves are provided on the outer peripheral wall of the support rod 16, and the plurality of second slide grooves are arranged along the axial direction of the support rod 16; a sliding hole is provided on the mounting block 11, and a plurality of sliders are provided on the inner hole wall of the sliding hole, and the plurality of sliders are arranged one-to-one with the plurality of second slide grooves; the mounting block 11 is slidably mounted on the support rod 16 through the sliding hole, and the plurality of sliders are respectively located in the second slide grooves corresponding to each other. In this way, the mounting block 11 can also slide along the axial direction of the support rod 16.

[0037] When the utility model is used for the grooving device of water and electricity installation, the route to be cut is marked on the wall where the groove is required by means of a spring line. After the marking is completed, the base is placed in a suitable position near the route to be cut and fixed, the handle 8 is turned to rotate the bidirectional threaded rod 9, and the two clamping blocks 6 move away from each other and separate from the turntable 5, that is, the turntable 5 is released, and then the turntable 5 is rotated to adjust the angle of the support rod 16 so that the axis of the support rod 16 is parallel to the marked route, and then the handle 8 is rotated in the opposite direction to rotate the bidirectional threaded rod 9 in the opposite direction, so that the two clamping blocks 6 move close to each other and clamp the turntable 5 to prevent the turntable 5 from rotating, and then the motor 13 is started again to drive the cutter 14 to rotate, and then the handle 10 is pulled to allow the mounting block 11 to slide along the axial direction of the support rod 16 with the U-shaped frame 12 and the cutter 14, so that the cutter 14 cuts and grooves the wall along the marked route, which can avoid errors in the grooves.
