Description

Technical Field

[0001] This invention relates to the field of ventilation and smoke extraction structure technology for power plants, and more specifically, to a ventilation and smoke extraction structure suitable for underground power plants in pumped storage power stations. Background Technology

[0002] The ventilation and smoke extraction structure of the underground powerhouse of a pumped-storage hydroelectric power station is a facility used to ensure air quality and safety within the underground powerhouse. This structure typically includes ventilation ducts, exhaust systems, and smoke extraction equipment. The underground powerhouse of a pumped-storage hydroelectric power station usually houses a large amount of equipment, generating heat and waste gases. The ventilation and smoke extraction structure removes these harmful gases and heat, ensuring air quality within the powerhouse and providing a comfortable working environment for staff.

[0003] Among them, a search revealed that patent application number CN202321308397.1 discloses a ventilation and smoke exhaust structure suitable for underground powerhouses of pumped storage power stations, including a main powerhouse ventilation and safety tunnel, a main transformer ventilation and safety tunnel, and a tailgate chamber ventilation and safety tunnel, which are respectively connected to one side of the underground powerhouse. The main powerhouse and auxiliary powerhouse are respectively connected to the branch tunnel of the geological exploration tunnel powerhouse through vertical shafts, and the branch tunnel of the geological exploration tunnel powerhouse is connected to the geological exploration tunnel.

[0004] When in use, this structure allows for the installation of a vertical shaft between the main plant and the geological exploration tunnel, based on their relative positions. This shaft connects the main plant and the geological exploration tunnel, and utilizes the existing cavern leading to the ground to improve ventilation and smoke extraction conditions during the plant excavation process. However, this structure cannot provide ventilation and smoke extraction from different directions, resulting in low exhaust efficiency and inconvenience during use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ventilation and smoke exhaust structure suitable for underground powerhouses of pumped storage power stations, aiming to solve the problems mentioned in the background art.

[0006] The present invention is implemented as follows: The present invention provides the following technical solution: a ventilation and smoke exhaust structure suitable for underground powerhouses of pumped storage power stations, including a flow guide seat for support, and a smoke exhaust component is provided on the flow guide seat;

[0007] The smoke exhaust assembly includes a heat exchange aluminum seat disposed on the top of the flow guide seat for heat exchange, and a support ring for support is disposed on the top of the heat exchange aluminum seat. A plurality of limiting grooves for limiting are distributed on the outer side of the support ring and along the circumference of the support ring's axis.

[0008] Each of the multiple limiting grooves is provided with a first guide tube for support, and each of the first guide tubes is provided with a flexible tube for guiding flow at its top.

[0009] The top of the support ring is provided with a reinforcing ring for limiting the position. A plurality of supporting connectors are distributed on the outer side of the reinforcing ring and along the circumference of the center point of the reinforcing ring. A second guide tube is provided on the top of each of the plurality of connectors, and each corresponding connector is connected to the second guide tube. The top of the reinforcing ring is provided with a gathering cylinder for supporting the position. The top of the gathering cylinder is provided with a guide cylinder for guiding the flow. A plurality of guide openings are distributed on the outer side of the guide cylinder and along the circumference of the center point of the guide cylinder. The baffle is movably connected to the guide cylinder.

[0010] As can be seen, in the above technical solution, when the first reinforcing guide impeller rotates, it draws the airflow outside the device into the gathering cylinder through the frame opening for gathering, and then draws it through the second reinforcing guide impeller. The airflow is discharged through the vent hole. When the second reinforcing guide impeller and the first reinforcing guide impeller rotate, the setting of the hose and the second guide pipe enables the external airflow to converge into the device synchronously with the device as the axis. The connector draws the airflow at the bottom of the device into the device, while the hose draws the airflow around the device into the device, thereby improving the airflow delivery efficiency and effect.

[0011] Optionally, in one possible implementation, the top of the guide tube is provided with a baffle for limiting the flow, the bottom of the baffle and inside the guide tube is provided with a first reinforcing guide impeller for drawing airflow, the bottom of the first reinforcing guide impeller and inside the guide seat is provided with a second reinforcing guide impeller for drawing airflow, both the second and first reinforcing guide impellers are provided with a rotating shaft, the top of the rotating shaft extends to the baffle and is detachably connected to the baffle, and the bottom of the guide seat is provided with a motor for driving the rotating shaft to rotate;

[0012] The bottom of each of the multiple connectors is provided with a limiting protrusion. The inner wall of the support ring and the circumference of the support ring axis are provided with several positioning vertical grooves that are respectively engaged with the bottom of the corresponding connector. The positioning vertical grooves are engaged with the limiting protrusions. The outer side of the heat exchange aluminum base and the circumference of the heat exchange aluminum base axis are provided with several vent holes, and each of the vent holes is provided with a heat exchange water pipe for heat exchange.

[0013] As can be seen, in the above technical solution, the motor starts and the output end of the motor drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the first and second reinforced guide impellers to rotate. The heat exchange aluminum base and the hot water pipe can exchange heat and cool the airflow, thereby reducing the heat energy discharged from the plant. Through the setting of the positioning vertical groove and the vent hole, the reinforcing ring and the butt joint are connected to the support ring through the positioning vertical groove and the vent hole, so that the airflow delivered through the second guide pipe can be introduced into the device. At the same time, it is also convenient to disassemble the various structures on the reinforcing ring.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. The present invention utilizes the rotation of a first reinforcing guide impeller and a second reinforcing guide impeller. When the first reinforcing guide impeller rotates, it draws the airflow outside the device through the frame opening into the gathering cylinder for gathering, and then draws it through the second reinforcing guide impeller, and discharges the airflow through the vent hole.

[0016] 2. When the airflow is discharged, the present invention can exchange heat and cool the airflow through the heat exchange aluminum base and the heat exchange water pipe, thereby reducing the heat energy of the flue gas discharged from the factory building.

[0017] 3. By setting up a hose and a second guide pipe, the present invention enables external airflow to converge synchronously into the device with the device as the axis point. The connector draws the airflow at the bottom of the device into the device, while the hose draws the airflow around the device into the device, thereby improving the airflow delivery efficiency and effect.

[0018] In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of various structures, the airflow is drawn into the gathering cylinder through the frame opening and then drawn out by the second reinforced guide impeller. The airflow is discharged through the vent hole. The airflow can be cooled by heat exchange through the heat exchange aluminum base and the heat exchange water pipe, thereby reducing the heat energy of the flue gas discharged from the plant. It can make the external airflow converge into the device synchronously with the device as the axis, improving the airflow delivery efficiency and effect. Attached Figure Description

[0028] As attached Figure 1-6 The diagram shows a ventilation and smoke exhaust structure suitable for underground powerhouses of pumped storage power stations. Through the smoke exhaust components installed on the guide seat 1, the airflow is drawn through the frame opening 15 into the gathering cylinder 10 for gathering, and then drawn through the second reinforced guide impeller 14. The airflow is discharged through the vent hole 18. The airflow can be cooled by heat exchange through the heat exchange aluminum seat 2 and the heat exchange water pipe 19, thereby reducing the heat energy of the flue gas discharged from the powerhouse. It can make the external airflow converge into the device synchronously with the device as the axis point, improving the airflow delivery efficiency and effect. The specific structural settings of the components are as follows.

[0029] The smoke exhaust assembly includes a heat exchange aluminum seat 2 set on the top of the flow guide seat 1 for heat exchange, a support ring 3 set on the top of the heat exchange aluminum seat 2 for support, and a number of limiting grooves 4 for limiting the position distributed on the outer side of the support ring 3 and along the circumference of the axis of the support ring 3.

[0030] Each of the multiple limiting grooves 4 is provided with a first guide pipe 5 for support, and each first guide pipe 5 is provided with a flexible hose 6 for guiding flow at its top.

[0031] The top of the support ring 3 is provided with a reinforcing ring 7 for limiting the position. A number of supporting connectors 8 are distributed on the outer side of the reinforcing ring 7 and along the circumference of the axis of the reinforcing ring 7. A second guide pipe 9 is provided on the top of each of the multiple connectors 8, and each corresponding connector 8 is connected to the second guide pipe 9. The top of the reinforcing ring 7 is provided with a gathering cylinder 10 for supporting the position. The top of the gathering cylinder 10 is provided with a guide cylinder 11 for guiding the flow.

The baffle 12 is movably connected to the guide cylinder 11.

[0032] The top of the guide tube 11 is provided with a baffle 12 for limiting the flow. The bottom of the baffle 12 and inside the guide tube 11 is provided with a first reinforcing guide impeller 13 for extracting airflow. The bottom of the first reinforcing guide impeller 13 and inside the guide seat 1 is provided with a second reinforcing guide impeller 14 for extracting airflow.

The top of the rotating shaft 21 extends to the baffle 12 and is detachably connected to the baffle 12. The bottom of the guide seat 1 is provided with a motor 20 for driving the rotating shaft 21 to rotate.

[0035] Furthermore, when the airflow is discharged, it can exchange heat and cool down through the heat exchange aluminum base 2 and the heat exchange water pipe 19, thereby reducing the heat energy discharged from the factory building by the flue gas.

[0036] Furthermore, when the second reinforced guide impeller 14 and the first reinforced guide impeller 13 rotate, the external airflow can be synchronously gathered into the device with the device as the axis point through the setting of the hose 6 and the second guide pipe 9. The connector 8 draws the airflow at the bottom of the device into the device, while the hose 6 draws the airflow around the device into the device, thereby improving the airflow delivery efficiency and effect.

[0037] Furthermore, through the positioning vertical groove 17 and the vent hole 18, the reinforcing ring 7 and the connector 8 are engaged with the support ring 3 through the positioning vertical groove 17 and the vent hole 18, so that the airflow delivered through the second guide pipe 9 can be introduced into the device, and at the same time, it is convenient to disassemble the various structures on the reinforcing ring 7.

Airflow is drawn into the gathering cylinder 10 through the frame opening 15 and then drawn out through the second reinforced guide impeller 14. The airflow is discharged through the vent hole 18. The airflow can be cooled by heat exchange through the heat exchange aluminum base 2 and the heat exchange water pipe 19, thereby reducing the heat energy of the flue gas discharged from the powerhouse. It can also make the external airflow converge into the device synchronously with the device as the axis, thereby improving the airflow delivery efficiency and effect.
