After rainfall or flooding, many pipe openings become clogged with silt and sand, affecting their usability. Currently, the main methods for clearing these pipe openings are manual cleaning and water jet flushing, which are inefficient. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a pipe clearing device to improve the efficiency of pipe hole clearing in cable duct corridors.

[0004] To achieve the above-mentioned technical objectives, this application provides a pipe-connecting device, including a device body and an auger drill bit;

[0006] The main body of the device is provided with multiple water outlets evenly distributed around the center line of the auger bit;

[0007] The water outlet direction of each of the aforementioned outlets is tangent to the trajectory circle where the water outlet is located;

[0008] The main body of the device is also provided with a water inlet for water to flow through each water outlet;

[0009] When water is sprayed from each of the outlet ends, the main body of the device rotates around the center line of the auger bit due to the reaction force of the sprayed water.

[0010] Furthermore, the auger drill bit includes a rod body and auger blades;

[0011] The helical blades are wound around the outer periphery of the rod body;

[0012] The rod has a pointed end extending from the helical blade;

[0013] The rod is fixedly connected to the main body of the device at the other end extending from the helical blade.

[0014] Furthermore, the rod body includes a cylindrical section and a conical section coaxially and integrally connected with the cylindrical end.

[0015] Furthermore, the other end of the rod is detachably connected to the main body of the device.

[0016] Furthermore, the main body of the device is provided with a connecting shaft;

[0017] The connecting shaft is provided with a first mating part at the end away from the main body of the device;

[0018] The other end of the rod is provided with a second mating part that is detachably connected to the first mating part.

[0019] Furthermore, the first mating part is a groove;

[0020] The second mating part is a protrusion that can be movably inserted into the groove;

[0021] The connecting shaft is provided with a through hole that communicates with the groove;

[0022] The portion of the protrusion extending into the groove is provided with a threaded hole corresponding to the through hole;

[0023] The first mating part and the second mating part are fastened together by a threaded fastener that passes through the through hole and is threadedly connected to the threaded hole.

[0024] Furthermore, the centerline of the auger bit coincides with the centerline of the main body of the device.

[0029] One end of the inlet pipe is connected to one end of each of the outlet pipes, and the other end of the inlet pipe is used to connect to a water source to form an inlet end.

[0030] Multiple water outlet pipes are distributed circumferentially around the center line of the auger drill bit, and each of them forms a water outlet end at its other end.

[0031] Furthermore, the main body of the device is provided with a water passage chamber;

[0032] The water passage chambers are connected at one end of each of the aforementioned water outlet pipes;

[0033] One end of the water inlet pipe is fixedly connected to the main body of the device;

The spiral drill bit is fixed on the main body and used to drill through pipe holes. The main body has multiple outlets evenly distributed around the center line of the spiral drill bit and tangent to the trajectory circle of the outlet end. These outlets are connected to the inlet end. After high-pressure water is input through the inlet end, the high-pressure water is ejected from the outlet end, causing the main body to rotate around the center line of the spiral drill bit due to the reaction force of the jet water flow, thereby driving the spiral drill bit to rotate. Utilizing the reaction force of the jet water flow to drive the spiral drill bit to rotate can effectively and gradually break down the hardened silt deposited in the pipe hole and use the jet water flow to carry the silt out, thus achieving the cleaning and unblocking of the pipe hole, improving the utilization rate of the constructed pipe gallery, saving money for power supply companies, and realizing the efficient utilization of urban underground space.

[0045] This application discloses a pipe-connecting device.

[0046] Please see Figure 1 as well as Figure 2 One embodiment of a pipe-connecting device provided in this application includes:

[0047] The main body of the device 2 and the auger drill bit 1.

[0048] The auger drill bit 1 is fixed on the main body 2 of the device and is used to drill through pipe holes.

[0049] The main body 2 of the device is provided with multiple water outlets 211 evenly distributed around the center line of the spiral drill bit 1. The water outlet direction of each water outlet 211 is tangent to the trajectory circle where the water outlet 211 is located. The main body 2 of the device is also provided with water inlet 221 for water to be supplied to each water outlet 211.

[0050] When water is sprayed from each outlet 211, the main body 2 of the device rotates around the center line of the auger bit 1 due to the reaction force of the sprayed water. After high-pressure water is input through the inlet 221, the high-pressure water will be sprayed out from the outlet 211, causing the main body 2 of the device to rotate around the center line of the auger bit 1 due to the reaction force of the sprayed water, thereby driving the auger bit 1 to rotate.

[0051] By using the reaction force of the jetting water flow to drive the auger bit 1 to rotate, the hardened mud and sand that has been deposited in the pipe hole can be effectively broken down step by step, and the mud and sand can be carried out by the jetting water flow, thereby cleaning and unblocking the pipe hole, improving the utilization rate of the constructed pipe gallery, saving money for power supply companies, and realizing the efficient use of urban underground space.

[0052] The above is Embodiment 1 of a pipe-connecting device provided in this application. The following is Embodiment 2 of a pipe-connecting device provided in this application. Please refer to the following for details. Figures 1 to 4 .

[0053] Based on the solution of Embodiment 1 above:

[0054] Furthermore, such as Figure 3 as well as Figure 4 As shown, the auger drill bit 1 includes a rod body 11 and a auger blade 12. The auger blade 12 is welded and fixed around the outer circumference of the rod body 11. Like a screw, it can gradually penetrate into the soil in the pipe hole by rotating. The end of the rod body 11 that extends out of the auger blade 12 is a pointed tip to facilitate breaking the soil. The other end of the rod body 11 that extends out of the auger blade 12 is fixedly connected to the main body 2 of the device.

[0055] Furthermore, the rod 11 includes a cylindrical section 112 and a conical section 111 coaxially and integrally connected with the cylindrical end. Compared with the pure cylindrical section 112 design, this design ensures that the diameter of the other end connected to the main body 2 of the device will not be too large under the same axial length, which is more conducive to installation and connection.

[0056] The auger drill bit 1 of this application can also be designed with reference to existing structures or directly used without restriction.

[0057] Furthermore, in order to facilitate the replacement of the appropriate auger drill bit 1 according to different hole sizes and to facilitate maintenance, this application designs the auger drill bit 1 and the device body 2 to be detachably connected, that is, the other end of the rod 11 is detachably connected to the device body 2.

[0058] Furthermore, such as Figure 3 as well as Figure 4 As shown, the main body 2 of the device is provided with a connecting shaft 24.

[0059] The connecting shaft 24 is provided with a first mating part (not shown in the figure) at one end away from the main body 2 of the device, and a second mating part 113 is provided on the other end of the rod 11 that is detachably connected to the first mating part.

[0060] Furthermore, the first mating part can be designed as a groove, and the corresponding second mating part 113 can be designed as a protrusion that can be moved into the groove.

[0061] The connecting shaft 24 has a through hole (not shown in the figure) connecting the groove, and the part of the protrusion extending into the groove has a threaded hole (not shown in the figure) corresponding to the through hole. The first mating part and the second mating part 113 are fastened together by a threaded fastener (not shown in the figure) passing through the through hole and threadedly connected to the threaded hole. During installation, the protrusion is inserted into the groove, and the threaded hole is aligned with the through hole. Then, the threaded fastener is screwed in to fasten the protrusion and the groove together. During disassembly, the threaded fastener is unscrewed to separate the protrusion and the groove. The threaded fastener can be a screw or a bolt, and there are no restrictions.

[0062] Furthermore, in order to make the overall structure compact, the auger drill bit 1 is designed so that its center line coincides with the center line of the device body 2. That is, after the auger drill bit 1 is fixed on the device body 2, its center line coincides with the center line of the device body 2.

[0063] Furthermore, such as Figures 1 to 4 As shown, the main body 2 of the device in this application can be in the form of a cylindrical structure. Taking this as an example, the auger drill bit 1 can be connected to the center position of one side of the main body 2, that is, the other end of the rod 11 is fixedly connected to the center position of one side of the main body 2.

[0064] Furthermore, the main body 2 of the device is provided with an inlet pipe 22 and multiple outlet pipes 21.

[0065] The centerline of the water inlet pipe 22 coincides with the centerline of the auger drill bit 1. Taking the main body 2 of the device as an example with a cylindrical structure, the water inlet pipe 22 can be fixed at the center of the other side of the main body 2. One end of the water inlet pipe 22 is connected to one end of each water outlet pipe 21, and the other end of the water inlet pipe 22 is used to connect to the water source, forming the water inlet end 221. The water inlet pipe 22 can be connected to the high-pressure water pipe by rotating the connector, and the high-pressure water pipe can be assisted by a glass pipe inserter to facilitate its entry and exit within the pipe hole; details are not elaborated here.

[0066] Multiple water outlet pipes 21 are distributed circumferentially around the center line of the auger drill bit 1, and each of them forms a water outlet end 211 at its other end. Taking the main body 2 of the device as a cylindrical structure as an example, each water outlet pipe 21 can be fixed on one side of the main body 2 of the device and evenly distributed around the connecting shaft 24. The shape of each water outlet pipe 21 is not limited, as long as the reaction force generated by the water jet from its water outlet end 211 can drive the main body 2 of the device to rotate.

[0067] Furthermore, in order to facilitate the connection between the inlet pipe 22 and the outlet pipe 21, a water passage cavity is provided inside the main body 2 of the device, and one end of each outlet pipe 21 is connected to the water passage cavity.

[0068] One end of the inlet pipe 22 can be connected to the water passage chamber, and then connected to each outlet pipe 21 through the water passage chamber.

[0069] Of course, one end of the inlet pipe 22 can be fixedly connected to the main body 2, and a branch pipe 23 can be set on the side wall of the inlet pipe 22 to connect itself to the water passage chamber, thereby realizing the connection with each outlet pipe 21. The design of the branch pipe 23 can strengthen the connection between the inlet pipe 22 and the main body 2, making it more reliable in use.

[0070] The above provides a detailed description of a pipe-connecting device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
