Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage engineering, in particular to a discharge device and a working method for self-adapting water level adjustment of self-drainage and forced drainage modes. Background Art

[0002] With the increasing attention paid to environmental protection and energy efficiency, the design and optimization of the discharge system has become the focus of attention in many fields. In many scenarios such as industrial production, sewage treatment, and rainwater discharge, discharge devices play a vital role. Traditional discharge devices usually adopt fixed discharge modes, such as self-drainage or forced discharge, and cannot be flexibly adjusted according to actual water level changes. In areas where the flood and low water levels of downstream rivers and lakes are quite different, this fixed-mode discharge device has the following problems in practical applications: First, the efficiency problem: when the water level is low, if the forced discharge method is still used, it will not only waste energy, but also may cause excessive wear of the discharge equipment. On the contrary, when the water level is high, if only the self-drainage method is used, the discharge efficiency may be seriously affected, resulting in untimely discharge or insufficient discharge capacity. Second, the energy consumption problem: the fixed discharge mode cannot be adjusted according to actual needs, resulting in low energy utilization efficiency. In the long-term operation process, this inefficient energy utilization may lead to significant cost increases. Third, the equipment life problem: the fixed-mode discharge device may cause the discharge equipment to operate under inappropriate working conditions, thereby shortening the service life of the equipment.

[0058] The utility model also provides a method for using a discharge device capable of adaptively adjusting the water level to self-drain and forced-drain modes, which is applicable to the first embodiment and the second embodiment described above, wherein the method for using includes:

[0059] Step 1: Installation and debugging:

[0060] Install the water level sensor 5 at an appropriate position to ensure that the water level can be accurately monitored; connect the drainage pump of the drainage pump station 2 to the pump station water inlet pipe 11 and the pump station water outlet pipe 12 to ensure that the water can be discharged smoothly; lay the self-drainage system drainage pipe 14 to ensure that the water can be discharged smoothly, connect the control system to the water level sensor 5, the first self-drainage system water inlet electric valve 7 (and the second self-drainage system water inlet electric valve 15 in the second embodiment), and the first forced drainage system water inlet electric valve 8 (and the second forced drainage system water inlet electric valve 16 in the second embodiment) to carry out preliminary debugging and testing.

[0061] Step 2: Water level monitoring and mode determination:

[0062] The water level sensor 5 monitors the water level in real time and transmits the water level data to the control system; the control system determines the current discharge mode to be adopted according to the preset water level threshold. For example, when the water level is lower than a certain threshold, the self-draining mode is adopted; when the water level is higher than another threshold, the forced discharge mode is adopted.

[0063] Step 3: Emission Mode Execution:

[0064] In the forced drainage mode, the first automatic drainage system water inlet electric valve 7 (and the second automatic drainage system water inlet electric valve 15 in the second embodiment) is controlled to be closed, the first forced drainage system water inlet electric valve 8 (and the second forced drainage system water inlet electric valve 16 in the second embodiment) is controlled to be opened, the drainage pump in the drainage pump station 2 is controlled to work, and sound and light warnings are provided to ensure that the water flow can be discharged quickly;

[0065] In the self-drainage mode, the first self-drainage system water inlet electric valve 7 (and the second self-drainage system water inlet electric valve 15 in the second embodiment) is controlled to open, and the first forced drainage system water inlet electric valve 8 (and the second forced drainage system water inlet electric valve 16 in the second embodiment) is controlled to close, and the natural water level difference is used for discharge.

[0066] Step 4: Energy Management and Optimization:

[0067] The power and energy management module adjusts energy consumption according to the current emission mode to achieve efficient use of energy.

[0068] In the forced drainage mode, although the drainage pump needs to be started, the overall energy consumption is still controlled at a low level because the running time of the drainage pump is short (it only runs when the water level exceeds the threshold).

[0069] In self-draining mode, energy consumption is lower because there is no need to start the drain pump.

[0070] Step 5: Monitoring and Maintenance:

[0071] Regularly inspect and maintain the device to ensure the normal operation of all components.

[0072] Furthermore, as a preferred embodiment, the working principle of the self-drainage system is to rely on gravity to discharge water from the urban drainage system into rivers, lakes and seas. It is suitable for low-lying areas without drainage, where there is a difference between the ground elevation and the downstream water level. It is characterized by low operating costs and no need for additional power equipment.

[0073] Furthermore, as a preferred embodiment, the working principle of the forced drainage system is to rely on the drainage pump station to pressurize the drainage into rivers, lakes and seas. It is suitable for low-lying areas with drainage, or areas where the natural ground elevation is lower than a certain frequency flood level (or tidal level in coastal areas). Its characteristic is that it can solve the drainage problem in low-lying areas.

[0074] Furthermore, as a preferred embodiment, the flow direction of drainage is controlled by controlling the electric gate valves of the self-draining system (the first self-draining system water inlet electric valve 7 and the second self-draining system water inlet electric valve 15) and the electric gate valves of the forced exhaust system (the first forced exhaust system water inlet electric valve 8 and the second forced exhaust system water inlet electric valve 16).

[0075] Further, as a preferred embodiment, it is preferred that discharge gates are installed at the discharge outlets of the self-drainage system and the forced discharge system to control the backflow of river water.

[0076] Further, as a preferred embodiment, the form of the water level sensor 5 should include but is not limited to a pressure sensor, a capacitive sensor, a float sensor, and an ultrasonic sensor.

[0077] Further, as a preferred embodiment, the installation position of the water level detection sensor 5 is determined according to the outlet positions of the self-drainage system and the forced drainage system, and should be at the high water level point around the outlets of the self-drainage system and the forced drainage system.

[0078] Furthermore, as a preferred embodiment, the drainage pump station 2 preferably uses a variable frequency pump and sets different pump start water levels and pump stop water levels.

[0079] Furthermore, as a preferred embodiment, in order to reduce energy consumption and installation costs and simplify land use procedures, the control gate well can be built in the pump station plant and use the same power supply as the drainage pump station.

[0080] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
