Abstract
The utility model relates to the technical field of reservoir operation, and discloses a reservoir emptying pipe valve replacement auxiliary device, which comprises a steel bushing with an opening at one side, wherein a flange is fixed at the opening end of the steel bushing, the other end of the steel bushing is connected with a breather pipe and a water pipe, and a water-stopping rubber ring is fixed on the outer edge of the end surface of the flange, which is far away from the steel bushing; the water-stopping rubber ring is pressed against the outer end face of a water discharge hole on a platform on the inner side wall of the dam body, a grating and an emptying pipe are fixed in the water discharge hole, and the emptying pipe penetrates through the outer extending end of the dam body and is provided with an emptying valve. The change of the emptying main valve can be completed under the condition that the domestic water of a downstream city is not influenced, and the change mode is simple and convenient.
Description
The technical field is as follows:
the utility model relates to a reservoir operation technical field, concretely relates to auxiliary device is changed to reservoir emptying pipe valve.
Background art:
the bottom of the dam body of the reservoir is generally provided with a vent pipe, the vent pipe mainly has the functions of emptying the reservoir and irrigating farmlands, and also has the function of providing a water source for domestic water of downstream cities, and a main valve of the vent pipe needs to be replaced due to the failure of the switch of the conventional main valve; however, when the emptying pipe valve is replaced, the reservoir water is required to be emptied, so that the domestic water of the downstream city is influenced.
The utility model has the following contents:
the utility model aims at overcoming prior art's is not enough, provides an auxiliary device is changed to reservoir emptying pipe valve, and it can accomplish the change to the main valve of emptying under the condition that does not influence low reaches city domestic water, and the change mode is simple, convenient.
The utility model provides a technical problem's scheme is:
an auxiliary device for replacing a reservoir emptying pipe valve comprises a steel sleeve with an opening at one side, wherein a flange is fixed at the opening end of the steel sleeve, a vent pipe and a water through pipe are connected to the other end of the steel sleeve, and a water stop rubber ring is fixed on the outer edge of the end face, far away from the steel sleeve, of the flange;
the water-stopping rubber ring is pressed against the outer end face of a water discharge hole on a platform on the inner side wall of the dam body, a grating and an emptying pipe are fixed in the water discharge hole, and the emptying pipe penetrates through the outer extending end of the dam body and is provided with an emptying valve.
One end of the breather pipe, which is far away from the steel sleeve, extends out of the water surface, and the water through pipe is arranged in the reservoir water.
The breather pipe is connected with a first valve, and the water service pipe is connected with a second valve.
The first valve and the second valve are both solenoid valves.
The utility model discloses an outstanding effect is:
compared with the prior art, the change of the emptying main valve can be completed under the condition of not influencing the domestic water of the downstream city, and the change mode is simple and convenient.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
in the first embodiment, as shown in fig. 1, the auxiliary device for replacing the emptying pipe valve of the reservoir comprises a steel sleeve 1 with an opening on one side, a flange 2 is fixed at the opening end of the steel sleeve 1, a vent pipe 3 and a water through pipe 4 are connected to the other end of the steel sleeve 1, and a water stop rubber ring 5 is fixed on the outer edge of the end face, away from the steel sleeve 1, of the flange 2;
the water-stopping rubber ring 5 is pressed against the outer end face of a water discharge hole 92 on a platform 96 on the inner side wall of the dam body 91, a grating 93 and an emptying pipe 94 are fixed in the water discharge hole 92, and an emptying valve 95 is arranged at the outer extending end of the emptying pipe 94 penetrating through the dam body 91.
Furthermore, one end of the breather pipe 3 far away from the steel jacket 1 extends out of the water surface, and the water service pipe 4 is arranged in the reservoir water.
More specifically, the air pipe 3 is connected to a first valve 71, and the water pipe 4 is connected to a second valve 72.
Further, the first valve 71 and the second valve 72 are solenoid valves.
The working principle is as follows: the device is hoisted by a crane and placed into water, and the flange 2 of the device is pressed against the end face of the water discharge hole 92 by an underwater camera, so that the water inlet end of the emptying pipe is blocked, and the water-stopping rubber ring 5 can improve the sealing property between the emptying pipe and the dam body;
emptying water in the emptying pipe, and then replacing the emptying pipe valve;
after the emptying valve is replaced, water is conveyed into the cylinder sleeve 1 from the second valve and the water through pipe by using the submersible pump, so that the emptying pipe is filled, the air pressure in the emptying pipe can be balanced by the first valve through the air pipe 3, the water filling work is convenient, and after the emptying pipe is filled with water, the water pressure in the emptying pipe and the water pressure outside the emptying pipe are equal, so that the device is convenient to lift by a crane;
the first valve and the second valve are electromagnetic valves, and the valves are conveniently controlled.
Finally, the above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant art can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
