Detailed Description
The following describes the embodiments and working principles of the present utility model in further detail with reference to the drawings.
As shown in fig. 1-3, a water inlet switching device for a pharmaceutical engineering project accident pool comprises a well body and a water inlet pipe 3, wherein the well body and the water inlet pipe are formed by a first well chamber 1 and a second well chamber 2, the first well chamber 1 is positioned above the second well chamber 2, an overhaul well cover 9 is arranged at the top of the first well chamber 1 and at the joint of the first well chamber 1 and the second well chamber 2, overhaul cat ladder 10 is arranged on the side walls of the first well chamber 1 and the second well chamber 2, the water inlet pipe 3 is used for communicating an upstream water inlet pipeline with the second well chamber 2, the second well chamber 2 is also connected with a first water outlet pipe 4-1 and a second water outlet pipe 4-2, the first water outlet pipe 4-1 is used for communicating the second well chamber 2 with a downstream water outlet pipeline, a first gate 5-1 and a second gate 5-2 are respectively arranged at the water inlets of the first water outlet pipe 4-1 and the second water outlet pipe 4-2, the first gate 1-1 and the second gate 5-2 are correspondingly connected with a first gate 1-6-5, and a second gate 2-1 and a second gate-6-1 are correspondingly arranged in the first gate-1 and the second gate-2 and a second gate-1-6-2 through the first gate-1 and the second gate-1-6-2.
In this example, the height of the manhole cover 9 at the top of the first well chamber 1 above the outdoor terrace is not greater than 0.15m, so as to avoid the influence on the ground, and thus the manhole cover is not limited by the arrangement site.
Preferably, the transmission mechanism 8 adopts a transmission screw, and is fixed on the inner wall of the second well chamber 2 through the shaft guide frame 7 by welding an embedded steel plate. Through the arrangement of the shaft guide frame 7, the movement direction of the transmission screw is ensured to coincide with the plumb line, so that the movement directions of the first gate 5-1 and the second gate 5-2 are controlled, and the on-off of the first water outlet pipe 4-1 and the second water outlet pipe 4-2 can be well controlled.
