Abstract

The utility model discloses a drainage structure for an outdoor cable duct, which includes the outdoor cable duct(1). A water accumulation ditch(2) is arranged on the bottom of the cable duct(1), a grid(3) is arranged on the water accumulation ditch(2), the bottom of the water accumulation ditch(2) is connected with a drainage pipe(4), another end of the drainage pipe(4) is communicated with a drainage inspection well(5), and a rotatable revolving door(7) is arranged on a pipe orifice at which the drainage pipe(4) is entered the drainage inspection well(5), the drainage inspection well(5) is provided with a discharge pipe(6). The structure of the utility model is simple, larger miscellany can be blocked to enter a drainage system, and reverse intrusion of a sewer is prevented, and the damage caused by reptile such as a rodent and the like entering the cable duct is avoided, thereby the safe and reliable working of the cable in the cable duct is guaranteed. Moreover, the utility model has the advantages that the construction is convenient, the implementation is easy and the like.

Description

Outside cable ditch water discharge structure

Technical field

The utility model relates to a kind of discharge structure, especially a kind of outside cable ditch water discharge structure.

Background technology

In civilian and industrial electric control field, following dual mode is adopted in outdoor buried cable laying usually: a kind of is the direct-burried cable installation in pipe; Another kind is that the cable trench crane span structure lays.First kind of mode is not easy to repair and maintenance, but investment is applicable to the general occasion of the less importance of cable radical than economizing; Second way easy access is safeguarded, but investment is bigger, is applicable to the big occasion of the more importance of cable radical.When adopting the outside cable ditch, rainwater etc. easily infiltrate in the ditch by its cover plate slit, need in time to get rid of ponding in the cable trench for avoiding causing security incident, traditional method is that cable trench is provided with the in line or submersible pump extraction ponding of sump employing pipeline, but pipeline directly discharges easy initiation of sewer to be poured in down a chimney, reptiles such as muroid may enter cable trench and damage, and submersible pump extraction ponding need provide power supply and adopt automatic control of liquid, invest bigger, the operating cost height only is lower than at the sump absolute altitude and uses when the sewer absolute altitude can not flow automatically discharging.

The utility model content:

The purpose of this utility model is: a kind of outside cable ditch water discharge structure is provided, and it can prevent that sewer from pouring in down a chimney and avoiding reptile such as muroid to enter cable trench and damage, thereby guarantees the safe and reliable work of ditch inner cable, to overcome the deficiencies in the prior art.

The utility model is achieved in that outside cable ditch water discharge structure, it comprises outdoor cable trench, be provided with the ponding ditch in the cable trench bottom, on the ponding ditch, be provided with grid, be connected with a gutter in the bottom side of ponding ditch, the other end and the drainage inspection well of gutter lead to, and are provided with rotary revolving door on gutter enters the mouth of pipe in the drainage inspection well, are provided with discharge pipe at drainage inspection well.

Preferably on gutter and the mouth of pipe that revolving door is connected, be provided with rubber ring.

Wherein, the orifice plane that is connected with revolving door of gutter and the angle α of vertical plane are 5～30 °.

And the angle that revolving door rotates on gutter is 0～90 °.

Described grid grizzly bar diameter is that 6～10mm, interval of grid strip are 15～30mm.

Since adopted technique scheme, compared with prior art, of the present utility model simple in structure, can hinder bigger foreign material and enter drainage system, and prevent that sewer from pouring in down a chimney, and avoid reptile such as muroid to enter cable trench damaging, thereby the safe and reliable work of ditch inner cable guaranteed.In addition, the utlity model has easy construction, advantages such as easy enforcement.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of gutter 4.

The specific embodiment

Embodiment 1 of the present utility model: outside cable ditch water discharge structure as shown in Figure 1, it comprises outdoor cable trench 1, is provided with ponding ditch 2 in cable trench 1 bottom, is provided with grid 3 on ponding ditch 2, grid 3 grizzly bar diameters are that 8mm, interval of grid strip are 20mm; Be connected with a gutter 4 in the bottom side of ponding ditch 2, the other end of gutter 4 and drainage inspection well 5 lead to, and on entering the mouth of pipe in the drainage inspection well 5, gutter 4 is provided with rotary revolving door 7, the angle that revolving door 7 rotates on gutter 4 is 0～90 °, the orifice plane that gutter 4 is connected with revolving door 7 and the angle α of vertical plane are 10 °, and are provided with rubber ring 8 on gutter 4 and the mouth of pipe that revolving door 7 is connected; Be provided with discharge pipe 6 at drainage inspection well 5.

Orifice plane that gutter 4 is connected with revolving door 7 and vertical plane keep an angle, so just can make and keep under the revolving door 7 self gravitation effects closing, prevented that muroid, reptile etc. from entering cable trench and damaging, the while does not also need to increase extra work and equipment goes to keep; When outside cable ditch 1 ponding, current are raised revolving door 7 by gutter 4 and are entered drainage inspection well 5 discharging, and drainage inspection well 5 water levels because reverse water pressure makes revolving door 7 be pressed on the mouth of pipe of gutter 4, can not pour in down a chimney when higher; And the mouth of pipe that gutter 4 is connected with revolving door 7 is provided with rubber ring 8, can increase the sealing that gutter 4 contacts with revolving door 7, has further reduced the possibility of pouring in down a chimney.Revolving door 7 is not suitable for too big at the rotational angle of gutter 4, rotate excessively and can't get back to initial position under action of gravity in order to avoid revolving door 7 occurs.
