[0002] Pumped-storage power stations have multiple functions such as peak shaving, valley filling, and energy storage, and are the key support for building a new power system that is clean, low-carbon, safe, reliable, intelligent, flexible, and economically efficient. In 2020, the total global installed capacity of pumped-storage power was 159.49 million kilowatts. Among them, the installed capacity of pumped-storage power in China was 31.49 million kilowatts, accounting for 19.7% of the global total, ranking first in the world in terms of scale.

[0003] In the construction of pumped-storage power stations, inclined and vertical shafts need to be built. As the "throat" of the water conveyance and power generation system of pumped-storage power station projects, inclined and vertical shafts are crucial for the construction of pumped-storage power stations. Inclined (vertical) shafts have characteristics such as large vertical height difference, greater excavation difficulty, complex geological environment, harsh climate environment, narrow working surface, many high-risk operations, and numerous construction processes, involving many major and above dangerous projects. Therefore, problems such as difficult construction and construction safety in inclined (vertical) shafts have continuously increased construction risks, and accidents such as collapse, falling from height, object strike, drowning, poisoning, and asphyxiation may occur, resulting in serious accident consequences.

The ventilation detection component 2, the ground pressure detection component 3, and the hydrological detection component 4 are connected to the monitoring center through the communication component 5. When in use, during the construction of the inclined and vertical shafts, detection holes are drilled at certain intervals on the inner wall of the construction shaft, and the detection holes are cleaned. Then, the end of the housing 1 with the hydrological detection component 4 is inserted into the detection hole, and the orifice of the detection hole is filled and sealed with a sealant to fix the housing 1. The ground pressure detection component 3 contacts the inner wall of the detection hole and is used to detect the change of ground pressure. The hydrological detection component 4 is used to detect the humidity and water pressure change in the detection hole. And the ventilation detection component 2 located outside the detection hole is used to detect information such as air humidity, wind speed, dust concentration, and harmful gas concentration in the construction inclined and vertical shafts. The detection device in one detection hole monitors one point, and by using the detection devices at multiple points, the ventilation, ground pressure, and rock stratum hydrological changes in the entire construction inclined and vertical shafts can be effectively monitored. The monitored information is transmitted to the monitoring center, and the monitoring center analyzes the information to judge the possibility of disasters, so as to timely handle them and prevent accidents such as collapses, falls from heights, object strikes, drownings, poisonings, and asphyxiations.

[0030] By setting up a monitoring center and a number of detection devices installed in the inclined shaft and vertical shaft, using the detection devices to effectively monitor the ventilation, ground pressure, and rock stratum hydrological information at each point, and then analyzing the obtained data through the monitoring center to judge the possibility of disasters, preventing accidents such as collapses, falls from heights, object strikes, drownings, poisonings, and asphyxiations.

[0031] Embodiment 2:

[0032] As Figure 3As shown in the figure, the ventilation detection component 2 includes a duct 6 installed at one end of the housing 1. When installed, the duct 6 is aligned with the direction of the inclined or vertical shaft. A ventilation detection component 7 is installed inside the duct 6. The ventilation detection component 7 is composed of multiple detection units, including a dust detection unit, a wind speed detection unit, an air humidity monitoring unit, and a harmful gas concentration detection unit. The dust detection unit, wind speed detection unit, air humidity monitoring unit, and harmful gas concentration detection unit can detect the dust concentration, air humidity, wind speed, and harmful gas concentration in the air. The ventilation detection component 7 is connected to the communication component 5 and can transmit the detected relevant information to the monitoring center to discover risks in a timely manner.

[0033] By setting the ventilation detection component 2 including the duct 6 and the ventilation detection component 7, it is possible to conveniently detect the dust concentration, air humidity, wind speed, and harmful gas concentration in the air of the inclined or vertical shaft.

[0034] Embodiment 3:

[0035] As Figure 3 shown in the figure, two fixing ears 8 are installed on the housing 1. Ear holes for fixing anchor bolts are provided on the fixing ears 8. An anti-slip nail 9 is installed on one side of the fixing ear 8. During use, two anchor bolts are symmetrically installed on both sides of the detection hole. The anchor bolts are passed through the fixing ears 8 and the nuts are tightened, so that the anti-slip nails 9 are driven into the rock formation, thereby fixing the housing 1 in the detection hole and fixing the position of the detection device.

[0036] By installing the fixing ears 8 with anti-slip nails 9 on the housing 1, it is possible to conveniently fix the detection device.

[0037] Embodiment 4:

[0038] As Figure 4 shown in the figure, the ground pressure detection component 3 includes a ground pressure detection component 10 installed inside the housing 1. A plurality of pressure sensors 11 are installed around the ground pressure detection component 10. One end of the pressure sensor 11 is installed with an elastic component 13. The elastic component 13 can be a spring or similar components. One end of the elastic component 13 is installed with a detection head 12. The detection head 12 extends outside the housing 1. During use, under the push of the compressed elastic component 13, the detection head 12 moves outward from the housing 1, so that the detection head 12 tightly presses against the inner wall of the detection hole. The elastic component 13 will detect an initial pressure value. When the inner wall of the detection hole is deformed under the action of ground pressure, the detection head 13 moves inward into the housing 1, thereby increasing the pressure on the pressure sensor 11 through the elastic component 13, so that the pressure value detected by the pressure sensor 11 becomes larger. The pressure sensor 11 transmits the data to the ground pressure detection component 10, and the ground pressure detection component 10 transmits the data to the monitoring center through the communication component 5. The monitoring center then analyzes the ground pressure change at this point to process it in a timely manner and avoid accidents.

[0040] Embodiment 5:

[0041] As Figure 5 shown, the hydrographic detection assembly 4 includes a hydrographic detection component 14 installed at the end of the housing 1. The hydrographic detection component 14 includes a humidity detection unit and a water pressure detection unit. The humidity detection unit detects the air humidity in the detection hole, and the water pressure detection unit, after the water in the detection hole increases and fills up, detects the water pressure in the detection hole, thereby monitoring the seepage of the rock formation. The hydrographic detection component 14 transmits the above information to the monitoring center through the communication component 5. The monitoring center analyzes and summarizes the information to judge the possibility of relevant risks occurring at this point, so as to process it in time, eliminate the risks, and make the construction safer.

[0042] By setting up the hydrographic detection component 14 including the humidity detection unit and the water pressure detection unit, it is possible to conveniently monitor the changes in humidity and water pressure in the detection hole.

[0043] Embodiment 6:

[0044] As Figure 5 shown, a sealing ring 17 is installed on the housing 1. The sealing ring 17 is tightly pressed against the inner wall of the detection hole, so that the hydrographic detection assembly 4 at the front end of the housing 1 can be located in the middle of the detection hole. In addition, a protective plate 15 is installed at the front end of the housing 1, and a plurality of connecting columns 16 are installed between the protective plate 15 and the housing 1. The hydrographic detection assembly 4 is protected by the protective plate 15 and the connecting columns 16 to prevent the rock from crumbling under the action of ground pressure in the detection hole and damaging the hydrographic detection assembly 4.

[0045] By installing the protective plate 15 and the connecting columns 16 at the front end of the housing 1, it is beneficial to protect the hydrographic detection assembly 4.

[0046] Embodiment 7:

[0047] As Figure 3 shown, an alarm 18 is installed at one end (the tail) of the housing 1. The alarm 18 is connected to the monitoring center through the communication component 5. When the monitoring center judges that an emergency may occur, the monitoring center sends information to the control end of the alarm 18 through the communication component 5, so that the alarm 18 emits an alarm, so that the nearby personnel can dispose of or evacuate in time to avoid a greater accident.

[0048] By installing the alarm 18 at one end of the housing 1, it is convenient to notify the nearby construction personnel to dispose of or evacuate in case of danger, thereby avoiding a greater safety accident.

[0049] Working principle: When in use, during the construction of inclined and vertical shafts, detection holes are drilled at certain intervals on the inner wall of the construction shaft, and the detection holes are cleaned. Then, the end of the housing 1 with the hydrogeological detection component 4 is inserted into the detection hole, and the orifice of the detection hole is filled and sealed with a sealant to fix the housing 1. The ground pressure detection component 3 contacts the inner wall of the detection hole and is used to detect the change of ground pressure. The hydrogeological detection component 4 is used to detect the humidity and water pressure change in the detection hole. The ventilation detection component 2 located outside the detection hole is used to detect information such as air humidity, wind speed, dust concentration, and harmful gas concentration in the construction inclined and vertical shafts. The detection device in one detection hole monitors one point, and by using the detection devices at multiple points, the ventilation, ground pressure, and hydrogeological changes in the entire construction inclined and vertical shafts can be effectively monitored. The monitored information is transmitted to the monitoring center, and the monitoring center analyzes the information to judge the possibility of disasters occurring, so as to process in time and prevent accidents such as collapse, falling from height, object strike, drowning, poisoning, and asphyxiation.
