[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0031] This embodiment is a combined downhole cable protector for oil and water wells.

[0032] As Figure 1 、 Figure 2 and Figure 3 shown, an arc connecting column 2 is fixedly connected to the upper side of the first base 1. The first base 1 is rotatably connected to the second base 5. The arc connecting column 2 is also provided on the upper side of the second base 5. A first connecting seat 3 is arranged on the upper side of the first base 1. A connecting groove 4 is opened inside the first connecting seat 3. The first connecting seat 3 is rotatably connected to the second connecting seat 6. A connecting groove 4 is opened inside the second connecting seat 6. A first connecting block 7 is fixedly installed on the rear side of the first base 1. The first connecting block 7 is rotatably connected to a threaded column 9. A second connecting block 8 is fixedly connected to the rear side of the first connecting seat 3. The second connecting block 8 is threadedly connected to the threaded column 9. A third connecting block 10 is arranged on the rear side of the second base 5. A round rod 12 is arranged on the upper side of the third connecting block 10. The round rod 12 is slidably connected to a fourth connecting block 11. The fourth connecting block 11 is fixedly installed on the rear side of the second connecting seat 6.

[0033] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, a first foam block 13 is provided below the inner side of the first base 1. The first foam block 13 is provided inside the second base 5. A second foam module 14 is provided above the inner side of the first connecting seat 3. The second foam module 14 is provided inside the second connecting seat 6. The first connecting seat 3 is slidably connected to the limiting rod 16. One side of the limiting rod 16 is fixedly connected to the first clamping plate 15. The other side of the limiting rod 16 is fixedly connected to the limiting block 17. A spring 18 is provided on the outer side of the limiting rod 16. The limiting rod 16, the limiting block 17 and the spring 18 are all symmetrically arranged up and down about the horizontal central axis of the first clamping plate 15. The first clamping plate 15, the limiting rod 16, the limiting block 17 and the spring 18 are arranged inside the second connecting seat 6. A second clamping plate 19 is provided inside the first base 1. The limiting rod 16, the limiting block 17 and the spring 18 are provided on the outer side of the second clamping plate 19. And the limiting rod 16 at the rear side of the second clamping plate 19 is slidably connected to the first base 1. In addition, the limiting rod 16, the limiting block 17, the spring 18 and the second clamping plate 19 are also provided inside the second base 5;

[0034] It should be noted that after the cables are connected together, the sealing performance of the connection part is inevitably not as good as that of the original cables. Therefore, it is necessary to protect it. When it is necessary to install this device outside the cable, remove the bolts from the outside of the first base 1, the second base 5, the first connecting seat 3 and the second connecting seat 6, and this device can be opened. Then place the cable inside this device. The inner diameters of the first foam block 13 and the second foam module 14 are smaller, which is convenient for clamping the cable. After the cable is clamped, close the first base 1, the second base 5, the first connecting seat 3 and the second connecting seat 6, and re-seal them with bolts, which can play a protective role. Specific Embodiment Two

[0035] This embodiment is to solve the problem that the lengths of the cables are different and it is not convenient for the protector to protect.

[0036] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in the initial state, the first connecting seat 3 and the first base 1 are connected together by an arc-shaped connecting column 2, and the second connecting seat 6 and the second base 5 are also connected together by an arc-shaped connecting column 2. When the lengths of the connections of the cable are different, the device can be adjusted according to the actual situation. Rotate the threaded column 9. Since the threaded column 9 is rotatably connected to the first connecting block 7 and the threaded column 9 is threadedly connected to the second connecting block 8, the rotation of the threaded column 9 will cause the first connecting seat 3 to move up and down on the upper side of the first base 1. Since the first connecting seat 3 is rotatably connected to the second base 5, the second base 5 will also move up and down synchronously. Therefore, the positional relationship between the second base 5 and the second connecting seat 6 will also change. In addition, a round rod 12 is provided at the rear side of the second base 5 and the second connecting seat 6. The round rod 12 is slidably connected to the fourth connecting block 11. The existence of the round rod 12 can ensure that the second base 5 and the second connecting seat 6 always remain consistent in the vertical direction. When the second base 5 rotates, the second connecting seat 6 will also rotate, playing a role of synchronous lifting and limiting. When the length adjustment is completed, the cable can be clamped and protected, and the operation is convenient. Specific Embodiment Three

[0037] This embodiment is to solve the problem of the cable shaking when being clamped.

[0038] As Figure 2 、 Figure 5 and Figure 6 shown, after the cable is placed inside the first clamping plate 15 and the second clamping plate 19, close the first base 1 and the second base 5. The first clamping plate 15 inside the first connecting seat 3 and the second connecting seat 6 will clamp the cable. Then, the limiting rod 16 will move outwards, and the spring 18 outside the limiting rod 16 will also undergo elastic deformation. The limiting block 17 plays a limiting role when opening the first connecting seat 3 and the second connecting seat 6, preventing the spring 18 from restoring elastic deformation and causing the limiting rod 16 at the rear side of the first clamping plate 15 to fall off from the first connecting seat 3. The same applies to the first clamping plate 15 inside the second connecting seat 6. In addition, when closing, the second clamping plate 19 inside the first base 1 and the second base 5 will also clamp the other part of the cable, preventing the cable from moving and playing a role in stable connection to enhance the stability of the connection.
