Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model provides a well pump line trapping devices, as shown in figure 1, including two semicircle pipes 2, each rigid coupling has two first fixed plates 21 on 2 extrados surfaces of every semicircle pipe, and first fixed plate 21 lays along the axial direction of semicircle pipe 2, and two first fixed plates 21 are located the both sides of semicircle pipe 2 to two first fixed plates 21 are located the coplanar towards one side of well pump line 1, and evenly seted up three fixed orifices 211 along the length direction of first fixed plate 21 on every first fixed plate 21 moreover. When two semicircle pipes 2 enclose and establish at well pump line 1 global, the staff can wear to establish the bolt in two relative first fixed plate 21's fixed orifices 211, then through mutually supporting of nut and bolt to it is fixed with two semicircle pipe 2 laminatings.
As shown in fig. 1, the first fixing plate 21 and the semicircular pipe 2 correspond to each other and are left at an interval, when two semicircular pipes 2 are clamped and arranged on the outer peripheral surface of the well pump pipe 1, the two first fixing plates 21 are arranged at intervals, and when the bolt and the nut are screwed mutually, the first fixing plates 21 are arranged at intervals, so that the deformation space of the first fixing plates 21 is reserved, the two semicircular pipes 2 are abutted to the end faces, and the gap is reduced.
As shown in fig. 1 and 2, a semicircular pressing plate 3 is fixedly connected to one end of each semicircular pipe 2 facing the flange 11, and a containing cavity 31 for containing bolts and nuts on the flange 11 is formed in one side of the pressing plate 3 facing the flange 11, so that when the pressing plate 3 is attached to the surface of the flange 11, the bolts are contained in the containing cavity 31, and gaps between the pressing plate 3 and the flange 11 are reduced. When liquid leaks from the joint of the well pump pipe 1 and the flange 11, the contact area between the pressure plate 3 and the flange 11 is increased, so that leaked moisture is not easy to diffuse on the flange 11, and the water blocking effect is improved.
As shown in fig. 3, in order to improve the connection tightness between the two pressing plates 3, a hoop 4 is arranged around the outer circumferential surfaces of the two pressing plates 3, the width of the hoop 4 is equal to the thickness of the pressing plates 3, a second fixing plate 41 is fixedly connected to each of the two ends of the hoop 4, a bolt is arranged on the two second fixing plates 41 in a penetrating manner, and the hoop 4 is tightly encircled on the outer circumferential surfaces of the two pressing plates 3 through the cooperation of the nut and the bolt, so that the contact end surfaces of the two pressing plates 3 are closer to each other, and a water blocking effect is achieved.
As shown in fig. 3, each pressure plate 3 is provided with 3 fastening assemblies 5 on the side facing away from the flange 11 for abutting against the flange 11. The fastening assembly 5 comprises a U-shaped limiting member 51, and one end of the U-shaped limiting member 51 is hinged to a side of the pressure plate 3 away from the flange 11. After the two semicircular pipes 2 are fixed to each other, the pressing plate 3 abuts against the surface of the flange 11, then the other end of the U-shaped limiting part 51 rotates towards the other side of the flange 11, and the other end of the U-shaped limiting part 51 is located below the flange 11, the other end of the U-shaped limiting part 51 is in threaded connection with a fastening bolt 52, the fastening bolt 52 is parallel to the axis of the well pump pipe 1, and the head of the fastening bolt 52 abuts against the lower surface of the flange 11 by screwing the fastening bolt 52 and the thread of the U-shaped limiting part 51, so that the side wall of the U-shaped limiting part 51 is driven to abut against the upper surface of the pressing plate 3, and the abutting tightness between the pressing plate 3 and the flange 11 is increased. Because all be provided with three fastening components 5 on every clamp plate 3 for each region of clamp plate 3 can both be stable receive the extrusion force of U type locating part 51, has reduced the space between clamp plate 3 and the flange 11, has played good effect of blocking water.
As shown in fig. 2, the intrados of every semicircle pipe 2 inlays and is equipped with annular first sealed pad 6, and first sealed pad 6 is located 2 border departments of semicircle pipe, along with the reciprocal anchorage of relative first fixed plate 21 for semicircle pipe 2 is inseparable leans on the outer peripheral face at well pump line 1 in turn, thereby drives first sealed pad 6 elastic deformation, makes first sealed pad 6 fill the gap of leaning on in turn between well pump line 1 and 2 inner walls of semicircle pipe, has played good effect of blocking water. And the inner wall of the semicircular pipe 2 is embedded with three separation sealing strips 7 along the axial direction of the well pump pipe 1, and the two ends of each separation sealing strip 7 are mutually connected with the corresponding first sealing gasket 6. When semicircle pipe 2 and well pump line 1 paste each other and lean on, through 6 boxes of first sealed pad of separating mutually supporting of sealing strip 7 for 2 inner walls of semicircle pipe form a plurality of airtight independent cavities that block water, thereby improved the effect that blocks water of mending leakage device.
As shown in fig. 2, an annular second gasket 8 is embedded in the side of the pressure plate 3 facing the flange 11, and the second gasket 8 is located at the edge of the pressure plate 3. When the pressing plate 3 is closely abutted to the flange 11, the second sealing gasket 8 fills up a contact gap between the pressing plate 3 and the flange 11 through elastic deformation, a good water blocking effect is achieved, and diffusion of leaked liquid is limited.
The implementation principle of the embodiment is as follows: the staff places two semicircle pipes 2 at the leak source department of well pump line 1 at first, then with clamp plate 3 inseparable leaning on flange 11 next to, through screwing each other of bolt and nut for two first fixed plates 21 that correspond lean on closely, then rotate U type locating part 51 to the opposite side of flange 11, twist through fastening bolt 52 soon, make clamp plate 3 and flange 11 next to lean on closely to realize the shutoff to the leak source.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
