Description

The utility model relates to the field of drainage systems and environmental protection, in particular to additional constructions of sewage pumping stations, is designed to dampen fluctuations in the influx of wastewater and accumulate them during emergency shutdown of pumps in automatic mode, as well as the operation of sewage pumping stations in conditions of restrictions for emergency sewage discharge.

There are devices for receiving and storing water.

A utility model is known (RU 2131500 C1 E03F 5/10 (1995.01) C02F 1/00 (1995.01) published on 10.06.1999), related to the construction of sewer systems, aimed at averaging the costs of domestic and industrial wastewater.

Common signs of the claimed utility model is the presence of pipelines, trays, the bottom of the chamber, chamber, storage tank.

Disadvantages: the lack of a control function to determine the period of minimum inflow of wastewater will require additional efforts from the maintenance staff when emptying the tank, the lack of automation of the sludge washing process will also require the introduction of additional resources for its implementation, if necessary, the pump will be stirred up with sewage, and additional pumping equipment will be required and costs operation, which together reduces its economic efficiency.

The closest in technical essence and adopted for the prototype is the device "Sewage pumping station (options)" (RU 107 195 U1 E03F 5/22, published on 08/10/2011, relating to the field of pumping wastewater for further treatment, can be used at any treatment plant and designed to improve the reliability of sewage pumping stations operating in a mode that does not allow interruption or reduction of wastewater supply.

Achieving this goal - the continuity of wastewater supply is carried out by a device consisting of: a branched inlet manifold into two parallel systems, each of which consists of a separate receiving tank with a supply pipe and a waste water discharge pipe. The outlet pipelines are connected to the pressure manifold, the valves on the inlet and outlet pipelines are installed in such a way that either of the two systems can be disconnected from the reception and supply of wastewater, and the reception of wastewater and its supply to the pressure collector will not be interrupted, since each of the parallel systems can work autonomously, each tank has a supply and exhaust ventilation, one electric pump.

A common feature of the claimed utility model with an analogue is: the presence of a receiving buried tank, an input sewage collector, controlled valves, supply pipelines.

A disadvantage of the known devices is significant material consumption and high operating costs, which together reduce their economic efficiency, the separation of the receiving tanks entails a significant increase in the cost of branching the network of pipelines and communications, the feasibility of their sectioning from the operational and economic point of view is obvious.

In addition, due to the lack of a technical solution for the organization of emergency release, there remains a risk of flooding by the sewage of adjacent territories and technological equipment in the event of an accident.

The presence of a new set of significantly distinctive features from the prototype in the inventive device for damping fluctuations in the influx of wastewater and their accumulation in sewage pumping stations allows us to conclude that the claimed utility model meets the criterion of "novelty."

The claimed utility model is aimed at creating a device to prevent negative impact on the environment and flooding of sewage pumping stations in the face of an increase in wastewater inflow or in cases of emergency stop of the main pumping units, as well as with restrictions or lack of the possibility of emergency release of sewage pumping stations. This utility model can be used in new construction, as well as reconstruction and modernization of water disposal systems.

The technical result of the claimed utility model is:

- in automating the process of distributing excess and emergency volume of wastewater and the functionality of the location of the damper collector (installation of the damper collector within the boundaries of roads with the possibility of changing in terms of its length, direction and configuration depending on the individual terrain conditions).

When manually activating the mode “Emptying the damper manifold”, the operating module 8 activates the opening of valves with an electric actuator 13, which is technologically mounted in a waste gravity pipe 12, which is technologically connected, via a power cable 20, to the operating module 18, thereby passing the entire accumulated volume through the passage channel gravity wastewater from the damper collector 8 through the intake chamber of the damper collector 4 and the gravity discharge pipe 12 to the receiving tank analysis pump station, thus opening a message between the receiving tank of the sewer pump station and the receiving chamber of the damper 4 and damper 8, also at the same time, the operation module 18 activates the opening of valves with an electric actuator 15 technologically mounted in the inlet gravity collector between the separation chamber 1 and the receiving tank of the sewage pumping station, technologically connected by means of a power cable 20 to the operating module 18, also at the same time, the operating module 18 activates the closure of valves with an electric actuator 3 technologically mounted in a bypass gravity pipe 2 between the separation chamber 1 and the receiving chamber of the damper manifold 4, technologically connected via a power cable 20 to the operating module 18, redirecting wastewater in the separation chamber 1, from the bypass gravity pipe 2, technologically connected to the separation chamber 1 and the receiving chamber damper collector 4, to the inlet gravity sewer collector, technologically connected to the separation chamber 1 and the receiving tank of the sewer pump station, thereby preventing sewage from entering the intake chamber of the damper collector 4, and directing them to the receiving tank of the sewer pump station, also simultaneously with this, the operating module 18 activates the closure of valves with an electric actuator 11 technologically mounted in the bypass gravity pipe 10, between the reception chamber of the damper manifold 4, and the receiving tank of the sewage pumping station, technologically connected via the power cable 20 to the operating module 18, all main pumping units are turned on during this period, regardless of the level of wastewater in the receiving tank of the sewage pumping station, as it decreases the working volume of wastewater in the receiving tank of the sewage pumping station to a minimum, the water level sensor 16 responds, which is technologically mounted in the zone N-2 of Fig.2 of the receiving The reservoir of the sewage pumping station and technologically connected via the communication cable 19 to the operation module 18, transmits a signal through the communication cable 19 to the operation module 18 to reach the operating level of the minimum mark, the operation module 18, in turn, also takes into account the data on emptying the damper manifold 8, obtained from the water level sensor 6, technologically mounted in the zone N-2 of FIG. 2 of the receiving chamber of the damper manifold 4 and technologically connected via the communication cable 19 to the operation module 18, activates the closure of the shut-off valves with the electric drive 13, which are technologically mounted in the discharge gravity pipe 12 between the receiving chamber of the damper manifold 4 and the receiving tank of the sewage pumping station, technologically connected by the power cable 20 to the operating module, and puts the device in the technological mode "Normal".
