In the utility model, the lower outside of described inner tube is welded with a circle arc strip, described arc strip opening down, the opening part of described arc strip be provided with can with the sealing ring of the cover plate fitted seal inner tube lower end mouth of pipe.
In the utility model, described band drain is bolted to connection in horizontal square tube.
The beneficial effects of the utility model are: the utility model can effectively solve the drainage problem of outside cable bottom of trench, by against current valve and gutter, cable trench internal water accumulation is drained into municipal wastewater well, make cable avoid being submerged by water, can protect the normal operation of cable security and assurance power system; Non retern valve in cable trench can draining can be closed again and effectively prevent from entering in cable trench in the toys such as snake, mouse automatically, can protect cable security; When water level is surging, water pressure increases also floats the stainless steel floating ball of cover plate lower end, and non retern valve is closed automatically, can effectively anti-sealing pours in down a chimney and enters in cable trench.The utility model flexibility is good, durable, price is low, draining is convenient, can protect well cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is use schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is top view of the present utility model.
The specific embodiment
As shown in Fig. 1 ~ Fig. 3, at the bottom of a kind of cable trench, establish automatic drain system, comprise non retern valve 1 and be connected on non retern valve 1 for sewage being drained into the gutter 2 of municipal wastewater well 20, described non retern valve 1 comprises and being parallel to each other and upper square substrate 3 of the same size and lower square substrate 4, on four jiaos of upper square substrate 3, be all provided with for connecting the L shaped adapting table 6 of upper square substrate 3 and lower square substrate 4, L shaped adapting table 6 is fixed on the bed course 5 of cable trench.Described L shaped adapting table 6 is between upper square substrate 3 and lower square substrate 4, L shaped adapting table 6 comprises perpendicular square tube 61 and the horizontally disposed horizontal square tube 62 of vertical setting, in horizontal square tube 62, undertake band drain 7, the middle part of described upper square substrate 3 and lower square substrate 4 is provided with square breach, the length of described band drain 7, width is less than respectively the length of square breach, width, on described band drain 7, be densely covered with drain hole 71, described gutter 2 is connected to the lower end of lower square substrate 4, gutter 2 inherences are vertically provided with the inner tube 8 for draining corresponding to the position of drain hole 71, described inner tube 8 is connected to the lower end of horizontal square tube 62, gutter 2 is hinged with the cover plate 9 that can seal the inner tube 8 lower end mouths of pipe by bearing pin 91, described cover plate 9 is positioned at gutter 2 inside, described cover plate 9 is welded with stainless steel floating ball 92 away from a side of inner tube 8.The utility model can effectively solve the drainage problem of outside cable bottom of trench, can cable trench internal water accumulation be drained into municipal wastewater well 20 by gutter 2, makes cable avoid being submerged by water, and can protect the normal operation of cable security and power system; Non retern valve 1 in cable trench can draining can close and effectively prevent to enter cable trench in the toys such as snake, mouse again automatically, can protect cable security; When water level is surging, water pressure increases also floats the stainless steel floating ball 92 of cover plate 9 lower ends, and non retern valve 1 is closed automatically, can effectively anti-sealing pours in down a chimney and enters in cable trench.The utility model flexibility is good, durable, price are low, easy to operate, can protect well cable.According to the feature of the non retern valve 1 at the bottom of cable trench, every 50 meters, fill this product to 100 meter amperes, by the drain function effectively promoting at the bottom of cable trench.
