Abstract
The utility model discloses the cable waterproof sealing device that a kind of underwater installation motor is used, comprise sealing gland, also comprise cable, described cable comprises outer jointing jacket and some wires, wire is connected by binding post with motor lines, and binding post outer wrap has high temperature heat-shrink tube; Described cable outside is provided with Rubber end.Adopt this kind of technical scheme, can avoid water from cable failure, to enter cable inside, then dirty along with inwall, the motor that enters into cable connection causes the damage of motor.
Description
Technical field
The utility model relates to cable waterproof technical field of sealing technology, relates in particular to the cable waterproof sealing device that a kind of underwater installation motor is used.
Background technology
Conventionally underwater installation, as immersible pump, blender, impeller etc., in the time of normally carrying out underwater operation, need to will connect extraneous energising equipment by cable.In use, if cable is damaged, just water may down flow to into underwater installation motor room along with the inwall of cable, cause motor damaged.
When the motor of underwater installation in the market needs stube cable, conventionally adopt at the outside waterproof seal that increases of cable, to avoid water to enter into device interior by the space of cable and underwater installation junction.If but in use; when the outer jointing jacket of cable is damaged, water just can enter into cable inside by breakage, and flows to along the inwall of cable the terminal equipment that cable connects; cause terminal equipment because water inlet suffers damage, increased the maintenance cost of underwater installation motor.
Utility model content
For solving above-mentioned technological deficiency, the utility model provides a kind of can enter the cable seal water-tight device of underwater installation inside by anti-sealing by cable failure place.
The technical scheme that the utility model adopts is: the cable waterproof sealing device that a kind of underwater installation motor is used, comprise sealing gland, also comprise cable, described cable comprises outer jointing jacket and some wires, wire is connected by binding post with motor lines, and binding post outer wrap has high temperature heat-shrink tube; Described cable outside is provided with Rubber end.
Further, described Rubber end is that neoprene is made.
Further, described high temperature heat-shrinkable tube adopts crosslinked soft flame retardant property polyethylene resin to make.
Further, described wire comprises conductor and insulation protective jacket, and insulation protective jacket is arranged at conductor outer surface.
Further, described oversheath adopts TPO material to make.
Further, between described wire and between wire and outer jointing jacket, be provided with packed layer.
Further, described packed layer is waterproofing unction.
Owing to having adopted technique scheme, the utility model can reach following beneficial effect: cable outside is provided with Rubber end, can directly effectively avoid water to enter into along cable outer wall and enter motor internal; When the outer jointing jacket of cable is damaged, water enters the inside of cable, and cable outside is provided with Rubber end, has avoided water to flow into motor internal along the insulation protective jacket outer wall of wire, causes burn-down of electric motor; When the outer jointing jacket of cable and the integument of wire are all damaged, water enters into wire inwall, because wire connects by binding post, in the middle of binding post, do not connect, water flows to behind binding post place, just can not continue the dirty motor that enters motor lines connection by binding post, thereby cause motor to be burned after avoiding water to enter motor; Between the wire that outer jointing jacket wraps up, be filled with waterproofing unction, the use of waterproofing unction is can wire more closely knit each other, and wire and outer jointing jacket are combined together, eliminates the gap of the two, further improves waterproof effect; The outer jointing jacket of cable adopts TPO material, has effectively avoided the internal penetration of moisture to cable.

Reference numeral: 1-motor lines, 2-high temperature heat-shrink tube, 3-binding post, 4-packed layer, 5-Rubber end, 6-cable, 61-outer jointing jacket, 62-wire, 621-insulation protective jacket, 622-conductor, 7-sealing gland.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is described in further details.
As shown in Figure 1, Figure 2 and Figure 3; the cable waterproof sealing device that this example provides a kind of underwater installation motor to use; comprise seal cover 7; also comprise cable 6; described cable 6 comprises outer jointing jacket 61 and some wires 62; wire 62 is connected by binding post 3 with motor lines 1, and binding post 3 outer wrap have high temperature heat-shrink tube 2.Described cable 6 outsides are provided with Rubber end 5, and Rubber end 5 can directly avoid water to flow to motor internal along cable 6 outer walls.During installation, sealing gland 7 compresses Rubber end 5 by bolt in fact, and Rubber end 5 can closely be fitted with motor, and effective anti-sealing enters into motor internal from Rubber end 5 and motor junction.
When the outer jointing jacket 61 of cable 6 is damaged, water enters into cable 6 inside, along inwall, toward dirty, while flowing to Rubber end 5, by Rubber end 5, is intercepted; When in cable 6, the insulation protective jacket 621 of wire 62 has breakage; water enters into wire 62; now water along with wire 62 inwalls toward dirty; because wire 62 is connected by binding post 3 with motor lines 1; when water flows to binding post 3; just stop continue flowing, effectively having stoped water to continue stream, to enter into the motor cavity that motor lines 1 connects inner, and then avoided motor entering water and damage.
Described outer jointing jacket 61 adopts TPO materials to make, and outer jointing jacket 61 adopts TPO materials to make, and has the characteristics such as relative density is little, water-tolerant, therefore adopt this kind of material can improve the waterproof effect of cable 6 due to polyolefin.
Described Rubber end 5 is neoprene head.Neoprene has good physical and mechanical properties, heat-resisting, resistance to combustion, and resistance to daylight, acid and alkali-resistance, chemical-resistant reagent, also has higher hot strength, percentage elongation and reversible crystallinity, and cementability is good, and hardness is at Hs50-55, and the class of insulation surpasses 50M Ω.Therefore the Rubber end of cable outside employing neoprene effectively exclusion of water enters motor internal.
Described high temperature heat-shrinkable tube 2 adopts crosslinked soft flame retardant property polyethylene resin to make.And the high temperature heat-shrinkable tube 2 internal diameter shrinkages of this kind of material are more than 50%, tensile strain rate ± 5; Applicable temperature is-55～125 ℃, together with being convenient to be sintered in cable 6.
Described stating between 62, wire and wire 62 and outer jointing jacket 61 is provided with packed layer 4; packed layer 4 is waterproofing unction; waterproofing unction can make between outer jointing jacket 61 and wire 62 and wire 62 more closely knit to each other; eliminated the space between 62, each wire, wire 62 and outer jointing jacket 61; it is combined together; water enters cable 6 inwalls, is stoped and continues toward dirty, and then effectively raise the water-proof function of cable 6 by waterproofing unction.
