Description
Technical field
The present invention relates to underwater installation electric power and field of signal transmissions, specifically is a kind of and the matching used diving joint-box of submersible pump.
Background technology
At present, submersible pump is used more and more widely, and it is all pull the plug a kind of water pump of work of the motor of pump housing impeller and drives impeller.Usually submersible pump is wanted the supporting control room that has in use, is provided with control cubicle etc. in the control room, and submersible pump just is connected with control cubicle by cable.According to the needs of actual operating position, the control room can be very near from submersible pump, also can be far, and that have even far away to hundreds of rice.Under many circumstances, near the influence of environment some submersible pump is subjected to, the control room can be far from submersible pump, and therefore, the cable that submersible pump is connected with control cubicle is the very long length of needs just, and it is long to have reached hundreds of rice sometimes.Because the weight of cable own is very heavy, even cable is also heavier than submersible pump sometimes, and it is inconvenient greatly that this brings just for transportation, installation and the maintenance of submersible pump.
In this case above, traditional junction box has on the spot appearred, and this junction box is along with electric pump is walked, meanwhile, it has been divided into two sections to cable: wherein one section is cable at random, and this section cable is used for connecting submersible pump and junction box, is generally about 10 meters; Other one section cable is very long, have in addition to reach hundreds of rice long, this section cable is used for connecting junction box and control cubicle.This junction box is generally one and is fixed on cubic casing on the ground, on casing, open several holes and be used for passing through cable, the aperture in these holes all diameter than cable is big, two sections cable ends in the casing connect with joint simultaneously, in the prior art herein be connected with various ways: have plenty of in the end of two sections cables and connect disk, two overlapping backs of disks are fixed with bolt and nut with centre bore; Have plenty of by adapter sleeve two sections cables are coupled together.
But there is following shortcoming in this traditional junction box:
1) because some electric pump is to be based upon the lower low-lying place of physical features, when coming, flood will flood the junction box, the outer cable of junction box and junction box all is in water like this, and have the several holes bigger on the casing than cable size, therefore, water is easy to enter in the junction box, like this, junction box's sealing property is bad, and its degree of protection is very low, can not work under water at all;
2) after the connected mode and the blow-by of two sections cables in the junction box, water enter in the junction box, can cause the short circuit between the interior two sections cables of junction box, cause submersible pump to be burnt out;
3) simultaneously, the connected mode of two sections cables and insecure in the junction box is easy to throw off, and therefore, causes the electric pump cisco unity malfunction.
Summary of the invention
Technical problem to be solved by this invention is that it is the diving joint-box of submerged type grade that a kind of good seal performance, its degree of protection are provided.
For solving the problems of the technologies described above, diving joint-box provided by the invention, comprise casing and the cable ends at random that in casing, is mutually permanently connected and the termination of output cable, this joint-box also comprises seal cover and outlet box, described seal cover is connected the top of casing, and has first sealing device in the contact position of seal cover and casing; Described outlet box is two, is connected to the two ends of casing, and has second sealing device in the contact position of each outlet box and casing; The outlet box that the termination of described cable ends at random and output cable is passed tank ends respectively is connected by water joint in casing, and the junction of described cable and outlet box has the 3rd sealing device.
Described first sealing device and second sealing device are sealing ring.
Described the 3rd sealing device comprises seal, rubber sleeve and has the loudspeaker mouth of axial pass trough, described seal is embedded in the cable outlet hole on the outlet box, described rubber sleeve is enclosed within outside the cable, described loudspeaker muzzle tightens up outside rubber sleeve and with screw, and an end and the seal of loudspeaker mouth push against.
The water joint of the junction of described two sections cables comprises high pressure self-adhesive tape, joint and bolt, described joint is two, one end of each joint is connected with the termination of cable ends or output cable at random respectively, the other end of each joint is connected to each other by bolt, and described high pressure self-adhesive tape looping is outside joint.
Described lower box is provided with the ponding chamber, at the top of ponding chamber the water leakage alarm electrode is installed.
The sidewall of bottom, described ponding chamber is provided with the dewatering orifice, and plug is located to be threaded in described dewatering orifice.
Described tank ends is respectively arranged with coil holder, has wire casing on the described coil holder, and described cable is positioned at wire casing and is fixed on the coil holder.
Described cable is many, and every is divided into two sections, correspondingly has a plurality of wire casings on the described coil holder, and every cable all is positioned at wire casing and is fixed on the coil holder.
The top of described outlet box is equipped with lifting bolt.
After adopting above structure, the present invention compared with prior art has following advantage:
1) since junction box's casing top connect with seal cover and the sealing of first sealing device arranged, tank ends is connected with outlet box respectively and the sealing of second sealing device is arranged, the sealing of the 3rd sealing device when passing outlet box, cable is arranged, like this, whole junction box is in sealing state fully, can reach the degree of protection of submerged type, thereby water advances less than in the casing, avoids occurring burning out because of short circuit the phenomenon of electric pump;
2) junction of two sections cables has adopted the joint of waterproof to connect in casing, even also can guarantee the sealing fully of joint under the situation that the junction box is leaked, thereby guarantees the safe operation of submersible pump more;
3) owing to be provided with the ponding chamber, and the water leakage alarm electrode has been installed,, has been improved fail safe greatly in case the junction box is leaked and understood operating personnel in the alert notice control room so at once at top, ponding chamber at lower box;
4) owing to fix cable with coil holder at the two ends of casing, make the layout of cable cleaner and tidier, make to disconnect more purposively between the cable, be more conducive to operation;
5) in addition, lifting bolt is installed, makes junction box's carrying convenient at the top of outlet box.
