Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases by those of ordinary skill in the art.
The embodiment of the application discloses distribution cable trench baffle.
Referring to fig. 1, in an embodiment of the present application, a distribution cable duct spacer includes: a separator body 3; the projection surface of the top surface of the partition board main body 3 along the vertical direction completely covers the bottom surface of the partition board main body 3; the side end faces of the separator body 3 are inclined faces.
Specifically, the partition body 3 may be a pyramid having a gradually decreasing cross-sectional area along the top surface to the bottom surface, and the side surfaces are inclined surfaces and are not likely to accumulate silt.
Referring to fig. 2, the main body 3 of the partition board can be placed between the cover board 1 and the wall of the cable trench 2 as a first cover board; accordingly, the cable trench 2 is provided with a receiving groove 21 for receiving the cover plate 1 and the partition body 3, and the length of the bottom surface of the partition body 3 is greater than that of the receiving groove 21. Referring to fig. 3, in the case where the partition body 3 is not provided, sand and mud are easily accumulated between the cover plates 1, so that the cover plates 3 are subjected to the extrusion force of the sand and mud at the side surfaces in addition to the gravity and the pulling force in the vertical direction when being lifted. Referring to fig. 4, the mud and sand on the two sides of the cover plate 3 cause the cover plate 3 to be subjected to a large static friction force when being lifted, before the cover plate 3 needs to be opened, power distribution personnel firstly need to pry the sand and stone around the cover plate by using small wood chips or small iron sheets, but due to long-term overstock, the density and hardness are high, the iron sheets wrapping the cover plate are also rusted in different degrees, and the cleaning is time-consuming and labor-consuming.
After the partition plate main body 3 is arranged, please refer to fig. 5 and 6, since the side surfaces of the partition plate main body 3 are all inclined surfaces, the silt is not easy to accumulate, and since the partition plate main body 3 has no relative movement tendency with the foundation, the partition plate main body 3 only receives the self gravity, the upward supporting force vertical to the foundation plane and the inward two supporting forces vertical to the inclined surfaces, and no friction force exists.
It should be noted that the partition plate main body 3 is square, and includes two long sides and two wide sides, and the width of the partition plate main body 3 is smaller than that of the cover plate 1; the width of the clapboard main body 3 is 1/n (n is more than 1) of the cover plate width, if the clapboard main body is made of the same material as the cable trench cover plate, the width of the clapboard is shortened to 1/n, the weight of the clapboard is also reduced to 1/n, and the lifting weight of an operator can be reduced.
The included angle between the side surfaces of the two long sides of the clapboard main body 3 and the vertical surface is beta, the included angle between the side surfaces of the two wide sides and the vertical surface is alpha, alpha is more than 0 degree and less than 90 degrees, and beta is more than 0 degree and less than 90 degrees. Specifically, if the width of the receiving groove 21 (shown in fig. 1 and 2) for receiving the main body portion of the partition board is W and the thickness of the partition board (shown in fig. 1) is H, then: 0< tan (α) < W/H; 0< tan (beta) < W/H.
Referring to fig. 7, the side surface of the partition body 3 may be a circular arc surface or a flat surface, without limitation.
The above is the first embodiment provided in the present application, and the following is the second embodiment provided in the present application, specifically referring to fig. 1, fig. 8 and fig. 9.
A distribution cable duct partition, comprising: a separator body 3; the projection surface of the top surface of the partition board main body 3 along the vertical direction completely covers the bottom surface of the partition board main body 3; the side end faces of the separator body 3 are inclined faces.
Further, the partition body 3 is provided with an operation hole 31; the operation hole 31 penetrates the top and bottom surfaces of the partition body 3; the operation hole 31 has a cross-sectional area gradually increasing from the top surface to the bottom surface.
Specifically, in the present embodiment, the operation holes 31 are two and are provided symmetrically with respect to the diaphragm main body 3.
In the present embodiment, the cross section of the operation hole 31 in the vertical direction is a right trapezoid, and the angle between the inclined side and the vertical plane is γ, where γ is greater than 0 ° < γ < 90 °.
Further, the device also comprises a locking device; the locking device comprises a fixed strip 4 and a connector 5; the first end of the fixing strip 4 is arranged in the wall of the cable trench; the connecting head 5 is disposed at the second end of the fixing strip 4, and is used for being locked and connected with the partition board main body 3.
Particularly, because of the baffle main part 3 weight is lighter, set up blocking device in cable pit 2, can play fixed and theftproof effect.
Further, the second end of the fixing strip 4 is disposed beside the operation hole 31, so that the operator can adjust the connector 5 through the operation hole 31.
Further, the connector 5 is connected with the partition body 3 by means of screw-fitting.
The baffle main part 3 that this scheme provided has greatly reduced the influence of silt deposit to the distribution cable line maintenance work, has greatly reduced the cable in the cable pit and has tourd the work degree of difficulty, has avoided many to patrol the blackspot, improves the quality and the efficiency that the distribution cable line tours. And the heavy mechanical trolley or the hoisting platform does not need to be carried, and the portable special opening hook tool only needs to be carried, so that the convenience and reliability are realized, and the burden of operators is reduced. In the aspect of installation and popularization, installing of baffle main part 3 does not influence the use of original apron 1, only need with baffle main part 3 place in conveniently observe the cable in the middle of the head with ditch the position of the circumstances such as ponding can, with low costs, simple to operate.
Although the present invention has been described in detail with reference to examples, it will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
