Description

Technical Field

[0001] This utility model relates to the field of trenching technology for hydropower installation, and in particular to automatic trenching equipment for hydropower installation. Background Technology

[0002] Water and electricity installation is an essential part of the design and decoration of a house. As an important hidden project in home decoration, water and electricity installation cannot be taken lightly during the construction process. Substandard water and electricity installation will not only affect the quality of life of the residents in the future, but also the installation of water and electricity channels. The process mainly involves cutting two parallel channels on the wall or bottom surface with a cutting machine, and then using an electric hammer to hollow out the space between the two channels.

[0003] For example, the authorized announcement number "CN220681258U" is named Automatic Grooving Equipment for Water and Electricity Installation. Through the structural design of the limiting component, it ensures the accuracy of the cutting depth and avoids the situation where the grooves cut into the wall are too shallow or too deep. The whole process realizes the standardization, normalization and precision of water and electricity grooving, which greatly improves the quality of water and electricity installation and has important application value for the interior decoration of buildings.

[0004] The above-mentioned and existing technologies have the following drawbacks: the groove depths for water pipes and electrical pipes are usually different. Since the limiting components of the grooving equipment do not have the function of adjusting to a fixed groove depth, the groove depth still needs to be manually controlled; the grooving for water and electricity installation requires the creation of a set of parallel lines, and the same water and electricity groove needs to be operated twice, which is relatively inefficient. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic trenching device for hydropower installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The design includes an automatic trenching device for water and electricity installation, comprising a first outer shell and a second outer shell. The inner walls of the first and second outer shells enclose an installation cavity. A third outer shell is located on one side surface of the first outer shell. A first rotating shaft is rotatably connected between the second and third outer shells, passing through the first outer shell. A first cutting blade is fixedly connected to the surface of the first rotating shaft. A second cutting blade and multiple spacers are slidably connected to the surface of the first rotating shaft, with the spacers positioned between the first and second cutting blades. A cutting through-hole is enclosed at the upper part of the first and second outer shells. The upper ends of both the first and second cutting blades extend out of the cutting through-hole. A mounting nut is threaded to the end of the first rotating shaft near the second cutting blade. A drive motor is located on one side surface of the third outer shell, and an output shaft is located on one side surface of the drive motor. The output shaft is connected to the first rotating shaft via a transmission assembly. Two mounting blocks are located at the upper end of the first outer shell, each with an adjustment device on its surface. Two handles are located on the lower surface of the third outer shell.

[0008] Preferably, the transmission assembly includes a first gear and a second gear, the first gear being disposed at one end of the output shaft, and the second gear being sleeved on the surface of the first rotating shaft, wherein the first gear and the second gear mesh and transmit power.

[0009] Preferably, the adjusting device includes an adjusting block, the adjusting block having multiple sets of equally spaced threaded grooves on one side surface near the mounting block from top to bottom, the mounting block having two sets of fixing through holes, each of the two sets of fixing through holes having a first bolt inside, the first bolt being threadedly connected to the threaded groove, and each of the two adjusting blocks having a sliding component at its upper end.

[0010] Preferably, the sliding component includes two support blocks, both of which are disposed on the upper end of the adjusting block, and a plurality of second rotating shafts are rotatably connected between the two support blocks, with rollers sleeved on the surfaces of the plurality of second rotating shafts.

[0011] Preferably, the second outer casing is provided with operating grooves on the front, rear, and lower surfaces. The operating grooves are provided with multiple second bolts, each of which penetrates one side of the inner wall of the operating groove and is threadedly connected to the first outer casing.

[0012] Preferably, the outer contour section of the second bolt is hexagonal, and a hexagonal groove is provided on one side surface of the second bolt.

[0013] The automatic grooving equipment for water and electricity installation proposed in this utility model has the following advantages: The adjustable device, through a first bolt passing through a fixing hole and threadedly connected to a threaded groove, can fix the adjusting block. Since one side surface of the adjusting block has multiple sets of equally spaced threaded grooves, the first bolt connects to these grooves at different heights, allowing for adjustment. Typically, the grooving depth for water pipes and electrical conduits is different; this grooving equipment can adjust the grooves to different fixed depths and lock the adjusting block, eliminating the need for manual control of the grooving depth. The transmission component, activated by holding a handle and starting the drive motor, rotates the output shaft, driving the first gear to rotate, which in turn drives the second gear. This, in turn, drives the first and second cutting blades through the first rotating shaft. This grooving equipment can create a set of parallel lines, requiring only one operation per water and electricity grooving, resulting in high efficiency. Attached Figure Description
