Description

Technical Field

[0001] The invention relates to the field of electrical technology, in particular to an underwater cable connecting plug with high sealing performance. Background Art

[0002] In the electrical field, especially in underwater electrical connections, how to ensure the sealing and waterproofness of electrical connectors has always been a key issue. During the use of electrical connections, due to the large range of cable use and long cable travel, two cables have to be connected, which will not only lead to a decrease in electrical performance, but may also cause safety hazards such as short circuits, posing a threat to the normal operation of equipment and personnel safety.

[0003] In the prior art, in order to achieve a good sealing effect, a large number of sealing and waterproof structures are added, which makes the installation operation cumbersome and complicated, which not only increases the installation cost and wastes a lot of materials, but also may cause the sealing performance to deteriorate due to improper operation. As for the accumulated water that has penetrated into the joint, the existing waterproofing lacks effective countermeasures. The accumulated water accumulates in the joint, which is not only difficult to discharge, but also difficult for people to find for a long time due to long-term immersion in water. In addition, there are multiple connectors in the cable connection, and the inspection intensity is large, resulting in more serious safety problems due to the inability to discover and deal with it in time. Summary of the invention

[0004] The object of the present invention is to provide an underwater cable connecting plug with high sealing performance to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A highly sealed underwater cable connection plug comprises a female plug, the inner wall of the female plug being slidably connected to a male plug for conductive transmission, the surfaces of the female plug and the male plug being sleeved with insulating tubes for protecting the normal operation of the male plug, a sleeve being fixedly connected to the surface of the insulating tube on the right side, a sealing mechanism for connecting to the sleeve being rotatably connected to the surface of the insulating tube on the left side, a pushing device for pushing the sealing mechanism being arranged inside the sealing mechanism, a reaction device for draining water being fixedly connected to the inner wall of the sealing mechanism, and a protective device for protecting the male plug being fixedly connected to the lower end of the reaction device.

[0007] As a further solution of the present invention, the sealing mechanism includes a sealing tube, an inner side wall of the sealing tube is fixedly connected to a first spring, an end of the first spring away from the sealing tube is fixedly connected to a movable sleeve, a rubber ring is fixedly connected to the lower end inside the sealing tube, and an end of the rubber ring away from the sealing tube is fixedly connected to the surface of the movable sleeve.

[0008] As a further solution of the present invention, the pushing device includes an airbag 1, a through hole is opened at the lower end of the airbag 1, and the through hole penetrates the interior of the insulating tube. A plurality of pressure relief holes are opened on the surface of the sealing tube.

[0009] As a further solution of the present invention, the reaction device includes a reaction chamber, conductive sheets are slidably connected on both sides of the interior of the reaction chamber, a storage space is formed between the conductive sheets and the inner wall of the reaction chamber, quicklime sheets are arranged in the storage space, and two symmetrically arranged contact sheets are arranged inside the reaction chamber, a wire is electrically connected between the two contact sheets, and the two wires are connected to the same alarm.

[0010] As a further solution of the present invention, the protection device includes a conduit, which is connected to the inner bottom surface of the reaction chamber, and one end of the conduit away from the contact piece is fixedly connected to a sealing airbag, and the conduit is connected to the sealing airbag.

[0011] As a further solution of the present invention, the inner wall of the sealing mechanism is fixedly connected with an internal thread, the surface of the sleeve is fixedly connected with an external thread, and the sleeve and the sealing tube are threadedly connected via the internal thread and the external thread.

[0012] As a further solution of the present invention, a circular ring is fixedly connected to the side wall of the sleeve, and the circular ring is inclined.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the present invention is used, by setting a movable sleeve, a rubber ring, an airbag 1, and a through hole, when the sleeve 4 and the insulating tube are threadedly connected, the side walls between the female plug and the male plug are in contact, and the gas enters the airbag 1 along the inner wall of the through hole. The through hole transports gas to the airbag 1. Due to the increase in the volume of the airbag 1, the movable sleeve is pushed to move to the left, and the mutual cooperation between the movable sleeve and the insulating tube makes the rubber ring bend and block the gap between the sealing tube and the insulating tube. This method is simple to operate, synchronized with the time, and prevents moisture from entering.

[0015] 2. When the present invention is used, a reaction chamber, a conductive sheet, quicklime slices, a conduit, and a sealing airbag are arranged. When water accumulates in the gap between the sleeve and the sealing tube, the accumulated water drips into the reaction chamber along the side wall of the sleeve. The quicklime slices in the reaction chamber come into contact with the water, and the quicklime slices will release a large amount of gas and heat, increase in volume, etc., thereby increasing the volume of the sealing airbag and fully protecting the surface of the male plug. This method is simple to operate and avoids the safety hazard of short circuit caused by accumulated water.

[0016] 3. When the present invention is used, a reaction chamber, a conductive sheet, a quicklime sheet, a contact sheet, a wire, and an alarm are arranged. The heat generated by the mutual reaction of water and quicklime sheets causes the conductive sheet to move to the side close to airbag 1, thereby causing the conductive sheet and the contact sheet to contact each other to form a closed circuit, so that the alarm sounds an alarm to remind construction workers to eliminate safety hazards in time. This method is simple to operate, synchronized with time, provides timely reminders, is eye-catching, and has high safety. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the pressure relief hole 63 and the airbag 61 to cooperate with each other, the airbag 61 is squeezed under the pressure of water to increase the pushing force on the movable sleeve 53, so that as the depth of the water changes, the pressure of the movable sleeve 53 also increases, and the force required to squeeze the rubber ring 54 is greater. A through hole 62 is provided at the lower end of the airbag 61, and the through hole 62 passes through the interior of the insulating tube 3. A plurality of pressure relief holes 63 are provided on the surface of the sealing tube 51, and the plurality of pressure relief holes 63 are discontinuously arranged.

[0034] The working principle of the present invention is: when in use, first connect the cables on both sides to 1 and 2 respectively, and then respectively sleeve 3 on the cables, male plug 2 and female plug 1, and then thread the sleeve 4 and the sealing tube 51 in opposite directions. Since there is air between the female plug 1 and the male plug 2, the side walls between the female plug 1 and the male plug 2 are in contact, and the air is pushed into the airbag 61. As the gas in the airbag 61 increases, the volume increases, and then the movable sleeve 53 is pushed to move to the left. The gap between the movable sleeve 53 and the sealing tube 51 becomes smaller, causing the rubber ring 54 to deform, filling the gap between the sealing tube 51 and the insulating tube 3, and preventing water from entering through the gap. When the installed cable device is placed in water, the airbag 61 is deformed due to the increase in pressure, and the volume in the airbag 61 becomes smaller, causing the airbag 61 to push the movable sleeve 53 to squeeze the rubber ring 54, preventing the pressure from increasing with the depth of the water. , water will enter the gap between the sealing tube 51 and the insulating tube 3. When water enters between the sleeve 4 and the sealing tube 51, the water enters the reaction chamber 71 along the side wall of the sleeve 4. Since there are quicklime slices 73 in the reaction chamber 71, the quicklime slices 73 react with water to release heat, pushing the conductive sheet 72 to move to the side close to the airbag 61. The temperature rises and the gas expands, and enters the sealed airbag 82 along the inner wall of the conduit 81. The sealed airbag 82 wraps the surface of the male plug 2, blocking the contact between the moisture and the male plug 2, avoiding the occurrence of safety hazards. When the conductive sheet 72 continues to move to the side close to the airbag 61, the conductive sheet 72 contacts the contact sheet 74, so that the conductive sheet 72, the contact sheet 74, the wire 75 and the alarm 76 form a closed loop, triggering the alarm, and when the quicklime slices 73 react with water, the heat generated will be transmitted to the airbag 61, causing the airbag 61 to expand due to heat, and then squeeze the rubber ring 54 again.
