Description

Technical Field

[0001] This utility model relates to the field of underground cable cutting equipment, specifically an underground cable cutting device. Background Technology

[0002] During injection well testing, it is often necessary to lower the testing instrument down the well via cable. Due to the recurring issue of instruments getting stuck in the testing sections, currently, once the instrument gets stuck, it requires repeated vibration to untangle it. The result of this repeated vibration is that most cables cannot be disconnected at the base, but rather in the middle. Disconnecting in the middle renders the entire cable reel unusable. Even disconnecting at the base damages some of the internal core wires, again resulting in the unusable reel. Each reel of cable is worth 60,000 yuan, and the operating cost per well is 30,000 yuan. Therefore, disconnecting or breaking cables in the middle results in significant economic losses. Under these circumstances, developing a device that can cut the cable at its base, thus preventing damage to the entire cable, is essential.

[0003] The present invention aims to solve the technical problems existing in the prior art, and to this end, proposes an underground cable cutting device. Utility Model Content

[0004] The purpose of this invention is to provide an underground cable cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A downhole cable cutting device includes a threaded cylinder, a fixing device is provided on one side of the threaded cylinder, the fixing device is threadedly connected to the threaded cylinder, the fixing device and the threaded cylinder cooperate, the cable passes through the fixing device and the threaded cylinder, and the fixing device is used to fix the cable.

[0007] The threaded cylinder is equipped with a drive mechanism inside, and a cutting device is provided at one end of the threaded cylinder. One end of the drive mechanism extends into the cutting device and engages with the cutting device. The cutting device is used to cut the cable.

[0008] As a further embodiment of this utility model: the fixing device includes a rotating cylinder, a handle is fixedly connected to the cylindrical surface of the rotating cylinder, a threaded groove is opened on the cylindrical surface of the rotating cylinder, the rotating cylinder is threadedly connected to the threaded cylinder through the threaded groove, and a number of clamping blocks are rotatably connected to the inner surface of the rotating cylinder, the number of clamping blocks cooperate with the threaded cylinder, and the number of clamping blocks are used to fix the cable.

[0009] As a further embodiment of this utility model: a fixing block is fixedly connected to one side of the threaded cylinder, and the other end of the fixing block is in sliding contact with the clamping block. The fixing block is used to squeeze the clamping block to make the clamping block tilt. A driving mechanism is provided on one side of the threaded cylinder, and an installation block is welded to one end of the threaded cylinder. A sliding groove is opened on one side of the installation block, and the sliding groove is slidably connected to the cutting device.

[0010] As a further embodiment of this utility model: the driving mechanism includes a driving motor, which is fixedly connected to the threaded cylinder. One end of the driving motor is fixedly connected to a driving shaft, and the cylindrical surface of the driving shaft is provided with meshing teeth that mesh with the cutting device.

[0011] As a further embodiment of this utility model: the cutting device includes a turntable and a cutter. The turntable is located in the threaded cylinder and rotates in contact with the threaded cylinder. A meshing groove is provided on one side of the turntable, and meshing teeth are located in the meshing groove and mesh with the meshing groove. A guide groove is provided on the other side of the turntable, and the guide groove is inclined.

[0012] As a further embodiment of this utility model: a push rod is fixedly connected to one side of the cutter, the push rod passes through the slide groove and is slidably connected to the mounting block, and the other end of the push rod extends into the guide groove and contacts the turntable, and the turntable drives the push rod to move through the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, one end of the cable passes through the rotating drum and the threaded drum. The rotating drum is driven to rotate by the handle, and the rotating drum drives the threaded groove to rotate. Since the rotating drum is threadedly connected to the threaded drum through the threaded groove, it moves horizontally when the rotating drum drives the threaded groove to rotate. The rotating drum drives the clamping block to move. Since one end of the fixed block is in sliding contact with the clamping block, the fixed block is fixed as the clamping block moves. That is, the clamping block tilts due to the pressure of the fixed block during the movement. That is, the greater the movement distance of the clamping block, the greater the tilt angle of the fixed block. That is, the other end of the fixed block is in contact with the cable. This device allows for easy fixing of cables of different diameters. Simultaneously, the drive motor controls the rotation of the drive shaft, which in turn drives the meshing teeth to rotate. As the meshing teeth engage with the meshing groove, they drive the turntable to rotate. The turntable then drives the guide groove to rotate. Due to the inclined design of the guide groove, one end of the push rod is located within the guide groove and slides in contact with the turntable. When the turntable drives the guide groove to rotate, it presses against the push rod, causing it to move. The push rod then drives the cutter to move and cut the cable. This device facilitates cutting the cable from its root, thus ensuring that the entire cable is not damaged. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0020] Please see Figure 1-3 In this embodiment of the utility model, an underground cable cutting device includes a threaded cylinder 1. A fixing device is provided on one side of the threaded cylinder 1. The fixing device is threadedly connected to the threaded cylinder 1. The fixing device cooperates with the threaded cylinder 1. The cable passes through the fixing device and the threaded cylinder 1. The fixing device is used to fix the cable.

[0021] The threaded cylinder 1 is equipped with a drive mechanism inside, and a cutting device is provided at one end of the threaded cylinder 1. One end of the drive mechanism extends into the cutting device and engages with the cutting device. The cutting device is used to cut the cable. This device facilitates cutting from the root of the cable, thereby ensuring that the entire cable is not damaged.

[0022] Please see Figure 1-2The fixing device includes a rotating cylinder 4, with a handle 5 fixedly connected to its cylindrical surface. A threaded groove 6 is formed on the cylindrical surface of the rotating cylinder 4, which is threadedly connected to a threaded cylinder 1 via the threaded groove 6. Several clamping blocks 15 are rotatably connected to the inner surface of the rotating cylinder 4, cooperating with the threaded cylinder 1. These clamping blocks 15 are used to fix the cable. One end of the cable passes through the rotating cylinder 4 and the threaded cylinder 1. The handle 5 drives the rotating cylinder 4 to rotate, which in turn drives the threaded groove 6 to rotate. Since the rotating cylinder 4 is threadedly connected to the threaded cylinder 1 via the threaded groove 6, it moves horizontally as it rotates, causing the clamping blocks 15 to move. Because one end of a fixing block 10 slides in contact with the clamping block 15, the fixing block 10 is fixed as the clamping block 15 moves. That is, the clamping block 15 tilts due to pressure from the fixing block 10 during its movement. The greater the distance the clamping block 15 moves, the greater the tilt angle of the fixing block 10. The other end of the fixing block 10 then fixes the cable, facilitating the fixing of cables of different diameters.

[0023] Please see Figure 1-2 A fixing block 10 is fixedly connected to one side of the threaded cylinder 1, and the other end of the fixing block 10 is in sliding contact with the clamping block 15. The fixing block 10 is used to squeeze the clamping block 15 to make the clamping block 15 tilt. A driving mechanism is provided on one side of the threaded cylinder 1, and an installation block 2 is welded to one end of the threaded cylinder 1. A sliding groove 8 is opened on one side of the installation block 2, and the sliding groove 8 is slidably connected to the cutting device.

[0024] Please see Figure 2 The driving mechanism includes a drive motor 14, which is fixedly connected to the threaded cylinder 1. One end of the drive motor 14 is fixedly connected to a drive shaft 13. The cylindrical surface of the drive shaft 13 is provided with meshing teeth 12, which mesh with the cutting device. The drive motor 14 controls the drive shaft 13 to rotate, and the drive shaft 13 drives the meshing teeth 12 to rotate. Since the meshing teeth 12 mesh with the meshing groove 11, the meshing teeth 12 drive the turntable 9 to rotate through the meshing groove 11.

[0025] Please see Figure 1-3 The cutting device includes a turntable 9 and a cutter 3. The turntable 9 is located in the threaded cylinder 1 and rotates in contact with the threaded cylinder 1. A meshing groove 11 is provided on one side of the turntable 9, and meshing teeth 12 are located in the meshing groove 11 and mesh with the meshing groove 11. A guide groove 16 is provided on the other side of the turntable 9, and the guide groove 16 is inclined.

[0026] Please see Figure 1-3A push rod 7 is fixedly connected to one side of the cutter 3. The push rod 7 passes through the slide groove 8 and is slidably connected to the mounting block 2. The other end of the push rod 7 extends into the guide groove 16 and contacts the turntable 9. The turntable 9 drives the push rod 7 to move through the guide groove 16. The turntable 9 drives the guide groove 16 to rotate. Since the guide groove 16 is inclined, one end of the push rod 7 is located in the guide groove 16 and slides in contact with the turntable 9. That is, when the turntable 9 drives the guide groove 16 to rotate, it squeezes the push rod 7 to move. The push rod 7 then drives the cutter 3 to move and cut the cable.

[0027] The working principle of this utility model is as follows: When the device is in use, one end of the cable passes through the rotating drum 4 and the threaded drum 1. The handle 5 drives the rotating drum 4 to rotate, which in turn drives the threaded groove 6 to rotate. Since the rotating drum 4 is threadedly connected to the threaded drum 1 through the threaded groove 6, the rotating drum 4 moves horizontally as it drives the threaded groove 6 to rotate. The rotating drum 4 also drives the clamping block 15 to move. Because one end of the fixing block 10 is in sliding contact with the clamping block 15, the fixing block 10 is fixed as the clamping block 15 moves. That is, the clamping block 15 tilts due to the pressure from the fixing block 10 during its movement. The greater the distance the clamping block 15 moves, the greater the tilt angle of the fixing block 10. The other end of the fixing block 10 then fixes the cable. This device allows for easy fixing of cables of different diameters. Simultaneously, the drive motor 14 controls the drive shaft 13 to rotate, which in turn drives the meshing teeth 12 to rotate. Since the meshing teeth 12 mesh with the meshing groove 11, the meshing teeth 12 drive the turntable 9 to rotate through the meshing groove 11. The turntable 9 then drives the guide groove 16 to rotate. Because the guide groove 16 is inclined, one end of the push rod 7 is located in the guide groove 16 and slides in contact with the turntable 9. That is, when the turntable 9 drives the guide groove 16 to rotate, it squeezes the push rod 7, causing the push rod 7 to move. The push rod 7 then drives the cutter 3 to move and cut the cable. This device facilitates cutting from the root of the cable, thus ensuring that the entire cable is not damaged.
