Description

Technical field The present utility model relates to the area of ​​a reservoir construction project, specifically a fully automatic groundwater extraction device for a reservoir. State of the art Due to the requirement to guarantee water quality in the city's water supply, a technical solution for extracting groundwater is used at the reservoir. To facilitate the operational management of water extraction, the traditional technical solution is often to provide a water extraction tower and a working bridge in the reservoir, with an electrically driven sluice (valve) opening and closing machine in the water extraction tower to control the water extraction from respective sub-layers. The biggest drawbacks of the solution are: 1. The construction investment for the water intake tower and the working bridge is high; 2. The project's construction is difficult and takes a long time; 3. The operation and maintenance of the gate are inconvenient; 4. Operating the project requires personnel supervision. Disclosure of the utility model Regarding the shortcomings of the traditional technical solution mentioned above, the present solution, based on the use of a buoyancy force of a floating chamber and a change in the floating chamber with a water level, directly controls the opening and closing of the sluice gate of the respective layer water extraction points in a fully automatic manner. To achieve the above objective, the present utility model is made possible by the following technical solution. A fully automatic layer water extraction device for a reservoir, consisting of a floating chamber gate opening and closing system, a water extraction branch line, an inlet pipe, an outlet pipe, and an outlet operating shut-off valve. Each layer extraction point is equipped with a specific floating chamber gate opening and closing system. The floating chamber gate opening and closing system consists of a floating chamber guide column and a floating chamber gate connecting rod. At the upper end of the floating chamber guide column, a limiting pin is provided for the sliding of a floating chamber up and down along the column. The floating chamber gate connecting rod is connected at its upper end to the floating chamber and at its lower end to a gate to form an opening and closing system that can operate independently. The gate located at an outlet end...The outlet operating shut-off valve controls the opening and closing of the reservoir's water supply. Furthermore, the swimming chamber comprises a swimming chamber body, on a left and right side of the swimming chamber body a swimming chamber positioning sleeve is provided, which is attached to the swimming chamber guide column, on the upper and lower side of which a stiffening plate is provided, which is connected to the swimming chamber gate connecting rod. Furthermore, the outlet pipe is planned to be located inside a water conduit tunnel. Furthermore, the gate is a flat steel gate; rollers are provided on the upper and lower sides of its left and right surfaces, and a rubber seal is provided on the inside of the roller. The advantageous effects of the present utility model consist of: 1. The technical solution does not require a different, electrically driven contactor opening / closing system, so the installation of a water intake tower and a working bridge is not necessary; 2. Construction investments and operating costs are saved by more than 60%, operational management is facilitated, and there is good dissemination and application value.

DesignsA fully automatic layer water extraction device for a reservoir, consisting of a float chamber gate opening and closing system, a water extraction branch line 20, an inlet pipe 30, an outlet pipe 40, and an outlet operating shut-off valve 50. Each layer extraction point is equipped with a specific float chamber gate opening and closing system. The float chamber gate opening and closing system consists of a float chamber guide column 11, a float chamber gate connecting rod 12, and a limiting pin 13 for sliding a float chamber up and down along the column is provided at an upper end of the float chamber guide column 11. The float chamber gate connecting rod 12 is connected at an upper end to the float chamber 14 and at a lower end to a gate 15 to form an opening and closing system that can operate independently. The gate located at an outlet end...The outlet operating shut-off valve 16 controls the opening and closing of the reservoir's water supply. As a further improvement of the present utility model, the swimming chamber 14 comprises a swimming chamber body 141, a swimming chamber positioning sleeve 142, which is attached to the swimming chamber guide column 11, is provided on each of the left and right sides of the swimming chamber body 141, and a stiffening plate 143, which is connected to the swimming chamber gate connecting rod 12, is provided on each of the upper and lower sides. As a further improvement of the present utility model, the outlet pipe 40 is provided within a water guide tunnel 60. As a further improvement of the present utility model, the gate 15 is a flat steel gate, rollers 151 are provided on an upper and lower side of its left and right surfaces, and a rubber seal 152 is provided on an inside of the roller 151. A key operating process of the fully automated layered water intake system of a reservoir is as follows: A gate at the outlet end of the discharge pipe is open; at the normal water level of the reservoir, the water flow enters a branch line and an inlet / outlet pipe through an upper-layer intake point; if the flow rate of a natural water inflow is less than the intake flow rate, the water supply causes a continuous lowering of the reservoir's water level; with the start of the water level drop, the float chamber at the lower-layer intake point changes from a fully submerged state to a semi-submerged state, and with the lowering, a gate of a lower sublayer is gradually opened; with the further lowering of the water level, the gates of the third and fourth layers are then opened...If the natural water inflow is greater than the water withdrawal flow, the reservoir's water level rises continuously: when the water level begins to rise, the float chamber at the water withdrawal point of the lowest layer gradually changes from a semi-submerged state to a fully submerged state, and with the rise of the float chamber, the sluice gate of the sublayer gradually closes, stopping water withdrawal from that layer; with the further rise of the water level, the closing process of the sluice gates of the third, second layer is also carried out as above. In summary, the core technology of the present device consists of enabling automatic control by means of the opening and closing of the water intake gate through the float chamber; construction investments and operating costs can be saved by more than 60%, operational management is simplified, and there is good distribution and application value.
