Detailed Implementation
[0006] Reference Figures 1-4 The aforementioned protective device for submersible cables used in oilfield development is characterized by comprising a submersible cable 1 and a protective device 2 inserted at the lower edge of the submersible cable 1. The protective device 2 has symmetrical protective grooves 3 at the middle of the left and right side surfaces. A connecting device 4 is connected to the middle of the lower edge of the front surface of the protective device 2. A clamping device 5 is rotatably inserted at the middle of the rear of the upper surface of the connecting device 4. A fixed support plate 6 is connected to the middle of the front edge of the upper surface of the clamping device 5. A connecting plug 7 is connected to the middle of the front surface of the connecting device 4.
[0007] In use, first, hold the rear end of the fixed support plate 6 with your fingers and pull it upwards. Then, rotate the clamping device 5 on the connecting device 4. Next, cut off the outer sheath of the submersible cable 1 to expose the wire. Then, place the submersible cable 1 inside the protective device 2 and insert the wire of the submersible cable 1 into the connecting shaft 4 and clamp it. Then, rotate the clamping device 5 to press the clamping device 5 onto the upper surface of the submersible cable 1 to fix the submersible cable 1. Finally, place your fingers in the anti-slip groove 3 and lift the protective device 2. At the same time, plug the connecting plug 7 into the submersible pump.
[0008] Furthermore, the protective device 2 includes a support plate 2-1, a rubber pad 2-2, a rubber strip 2-3, and anti-slip textures 2-4. The rubber pad 2-2 is connected to the middle of the lower surface of the support plate 2-1, and the rubber strip 2-3 is connected to the middle of the lower inner surface of the support plate 2-1. Several anti-slip textures 2-4 are provided at the middle of the rear edge of the lower inner surface of the support plate 2-1. The support plate 2-1 is concave in shape. The submersible cable 1 is inserted into the upper surface of the support plate 2-1. The size of the support plate 2-1 is matched with the size of the front end of the submersible cable 1.
[0009] In use, first place the submersible cable 1 inside the tray 2-1, insert the wire on the submersible cable 1 into the connecting shaft 4 and press it tight. Then rotate the clamping device 5 to press the clamping device 5 onto the upper surface of the submersible cable 1. At the same time, the friction is increased by the rubber strip 2-3 and the anti-slip texture 2-4. Finally, the rubber pad 2-2 reduces the wear between the tray 2-1 and the outside.
[0010] Furthermore, the connecting device 4 includes a housing 4-1, insertion holes 4-2, bolts 4-3, and notches 4-4. Several insertion holes 4-2 are evenly distributed in a horizontal row at the middle of the rear surface of the housing 4-1. Several bolts 4-3 are evenly distributed in a horizontal row at the middle of the upper surface of the housing 4-1. Notches 4-4 are symmetrically distributed on the left and right rear edges of the upper surface of the housing 4-1. The positions of the insertion holes 4-2 correspond to the positions of the bolts 4-3. The bolts 4-3 penetrate the upper surface of the housing 4-1 and are inserted into the insertion holes 4-2. The rear surface of the housing 4-1 is connected to the front surface of the support plate 2-1.
[0011] When using it, first insert the wire on the submersible cable 1 into the socket 4-2, then rotate the bolt 4-3 to press and fix the wire on the submersible cable 1, and then push the clamping device 5 to rotate in the slot 4-4.
[0012] Furthermore, the pressing device 5 includes a pressure plate 5-1, a rotating plate 5-2, pins 5-3, and files 5-4. The rotating plate 5-2 is symmetrically connected to the middle of the left and right edges of the lower surface of the pressure plate 5-1. The pins 5-3 are symmetrically connected to the middle of the left and right edges of the rear surface of the pressure plate 5-1. Several files 5-4 are connected to the middle of the upper edge of the rear surface of the pressure plate 5-1. The rotating plate 5-2 is rotatably inserted into the notch 4-4. The rotating plate 5-2 and the interior of the notch 4-4 are connected to each other by a rotating shaft. The position of the pins 5-3 corresponds to the position of the rubber strip 2-3. The size of the pressure plate 5-1 matches the internal size of the support plate 2-1.
[0013] In use, first press down on the pressure plate 5-1 with your finger while rotating the rotating plate 5-2 in the groove 4-4. Then, press the pressure plate 5-1 onto the upper surface of the submersible cable 1, and at the same time, insert the pin 5-3 through the wires inside the submersible cable 1. Finally, insert the pin 5-3 into the support plate 2-3 to fix the submersible cable 1. At the same time, the file pin 5-4 and the anti-slip texture 2-4 work together to increase the friction between the submersible cable 1, the label 2-1, and the pressure plate 5-1, which can prevent the submersible cable 1 from moving in the support plate 2-1.
