A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
As shown in fig. 1 to 4, the water draining power tube according to the embodiment of the present invention includes a tube body, a cable 200 is inserted into the tube body, and the tube body includes a horizontal tube 1 and an elbow 2 connected to the horizontal tube 1, wherein the horizontal tube 1 is buried underground, one end of the elbow 2 far away from the horizontal tube 1 is located in a cable well 100, an outer arc surface of the elbow 2 is provided with a plurality of water draining holes 21, a height of each water draining hole 21 is smaller than a height of a lowest surface of an inner side wall of the horizontal tube 1, and a height of one end of the water draining hole 21 communicating with the elbow 2 is larger than a height of one end communicating with an outside of the elbow 2. Through set up wash port 21 in the extrados of elbow 2, and the position of wash port 21 is less than horizontal pipe 1, can discharge rapidly when the elbow 2 is interior ponding, effectively prevent that ponding from entering into horizontal pipe 1 in, influence cable 200's life, and set up wash port 21 into the mode that the inner high outer end is low, prevent that the falling into water of top from entering into in elbow 2 like rainwater in this wash port 21.
Specifically, the pipe body is a PVC pipe, the hardness of the PVC pipe is greater than that of the cable 200, the design can effectively prevent an external structure from extruding the cable 200, the integrity of an external protection layer of the cable 200 is ensured, and the service life of the cable 200 is prolonged.
In the present embodiment, the drainage hole 21 is an L-shaped structure, specifically, the drainage hole 21 includes an inclined section 211 and a horizontal section 212, the inclined section 211 is inclined from top to bottom, the inclined section 211 is adjacent to the inner side of the elbow 2, the horizontal section 212 is communicated with the inclined section 211, and the horizontal section 212 is adjacent to the outer side of the elbow 2. The drain holes 21 with the curved structure can slow down the backflow of external water into the elbow 2.
Specifically, the included angle between the inclined section 211 and the horizontal section 212 is greater than 120 degrees.
In other embodiments, the drain hole 21 may be a straight hole structure with a slope, and the drain hole 21 is disposed from the inside of the elbow 2 to the outside with a slope downward, and this design may also prevent the outside water from falling into the drain hole 21 and flowing back into the inside of the elbow 2.
In an embodiment, the outer arc surface of the elbow 2 is concavely provided with a receiving groove 22, the groove bottom of the receiving groove 22 is spaced from the inner side wall of the elbow 2, the drain hole 21 is formed at the groove bottom of the receiving groove 22, and a sealing plate 3 for sealing the drain hole 21 is movably arranged in the receiving groove 22. The sealing plate 3 mainly prevents external water from flowing backward into the elbow 2 when the water level in the cable well 100 rises sharply and exceeds the drain hole 21, and meanwhile, the movably arranged sealing plate 3 does not influence the drainage of accumulated water in the elbow 2 under normal conditions.
In this embodiment, the horizontal section 212 communicates with the bottom of the accommodating groove 22.
Further, the upper end of the sealing plate 3 is rotatably connected with the groove wall of the accommodating groove 22 through a rotating shaft 4, the sealing plate 3 has a blocking side surface 31 close to the groove bottom of the accommodating groove 22, and the blocking side surface 31 is tightly attached to the groove bottom of the accommodating groove 22. Because the wash port 21 is the slope decurrent, ponding water level in elbow 2 is when wash port 21, push aside shrouding 3 under the action of gravity of water, make shrouding 3 rotate, and then guarantee the tank bottom separation of shrouding 3 and holding tank 22, ponding in elbow 2 overflows along the arrow direction of figure 3, and when the water level of cable shaft 100 rises sharply, outside water pressure can be followed the arrow B direction of figure 2 and compressed tightly shrouding 3 in holding tank 22, make outside water can not enter into elbow 2 in, and then guarantee that water can not enter into longer horizontal pipe 1.
Specifically, the tank bottom of holding tank 22 is the arc, shrouding 3 for with the tank bottom assorted arc of holding tank 22. Elbow 2 is the arc because the structure is special, consequently is the arc at the tank bottom that holding tank 22 was seted up to its cambered surface, can reduce elbow 2's wall thickness requirement, and then reduces material cost, and shrouding 3 is the arc, can make shrouding 2 can paste tightly in holding tank 22's tank bottom, guarantees that outside water does not enter into in the elbow 2.
In this embodiment, the blocking side surface 31 of the sealing plate 3 is provided with a blocking column 32 corresponding to each drainage hole 21, the blocking column 32 is inserted into the drainage hole 21, and the blocking column 32 is a rubber column. The plugging column 32 made of rubber is inserted into the drainage hole 21, so that the sealing performance of the sealing plate 3 when water exists outside the elbow 3 can be enhanced.
Specifically, the closing plate 3 and the plugging column 32 are integrally formed by injection molding of rubber. An organic whole injection moulding can reduce the manufacturing and the equipment degree of difficulty of shutoff post 32, simultaneously, when 2 outsides of elbow have water, can extrude shrouding 3 emergence deformations of rubber material, and then promote sealed effect.
Preferably, the length of the blocking column 32 is not greater than one-half of the length of the drainage hole 21. This design is in order to guarantee that elbow 2 is inside to have water, and when elbow 2 outside does not have water, the inside hydroenergy of elbow 2 can be smoothly with shrouding 3 back-off drainage, in addition, the horizontal segment 212 that the cooperation level set up can guarantee that the grafting and the separation of shutoff post 32 are more smooth and easy.
In one embodiment, as shown in fig. 5, the tube body includes an outer tube 5 and an inner tube 6 spaced apart from each other, a honeycomb buffer layer 7 is disposed between the inner tube 5 and the outer tube 6, and the cable 200 is inserted into the inner tube 5. Through setting up double-deck pipe box and establishing cable 200, and set up the support intensity that honeycomb buffer layer 7 can strengthen whole pipe body, prevent effectively that pipe body from being extruded deformation or breaking.
In this embodiment, the drainage hole 21 is disposed on the outer tube 6, a transition hole is disposed on the inner tube 5 corresponding to the drainage hole 21, the drainage hole 21 is communicated with the transition hole, the height of the transition hole is greater than the height of the drainage hole 21, and the height of the transition hole is less than the height of the lowest surface of the inner side wall of the horizontal tube 1. Through set up the transition hole on inner tube 5, can discharge the ponding that soaks in inner tube 5, prevent that water from getting into in horizontal pipe 1.
In the present embodiment, the hardness of the outer tube 6 is greater than that of the inner tube 5, and the hardness of the inner tube 5 is greater than that of the cable 200. Through outer tube 6 and the inner tube 5 that sets up the ladder hardness, can reduce material cost when guaranteeing to implement effectual protection to cable 200, the hardness of outer tube 6 is greater than inner tube 5 in addition, consequently, the toughness of inner tube 5 is greater than outer tube 6, after outer tube 6 breaks, the inner tube 5 of toughness can block ruptured outer tube 6, prevent that cable 200 in the inner tube 5 from being stabbed, and the hardness of inner tube 5 is greater than cable 200's hardness again, cable 200's outer protective layer is softer, inner tube 5 can form the secondary protection.
