Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically to an environmental monitoring device for the construction of a storage power station cavern. Background Technology

[0002] Pumped storage power station caverns are the core component of the underground powerhouse system. They typically refer to a group of tunnel-like underground spaces artificially excavated inside a mountain to house key facilities such as generator sets, transformers, and water pipelines. Because the caverns are underground, they generate a lot of dust and face poor ventilation during construction. Therefore, monitoring equipment is needed to monitor the construction environment.

[0003] However, existing environmental monitoring equipment for the construction of pumped storage power station caverns is usually placed on the ground of the cavern for mobile use. During the movement of the monitoring equipment, a certain amount of ground space is required, and the equipment can easily interfere with the construction on the cavern floor, making it inconvenient to move and use the monitoring equipment inside the cavern. In addition, existing construction environmental monitoring equipment is usually fixed at a suitable height above the ground by a support frame, but the height of the support frame cannot be adjusted. When it is necessary to monitor the air quality above the cavern, the height limitation may prevent the monitoring from being completed, which is not conducive to the monitoring equipment monitoring the air quality at different heights above the cavern. Utility Model Content

[0004] The purpose of this utility model is to provide a monitoring device for the construction environment of a storage power station cavern, in order to solve the problems mentioned in the background art, such as the ease with which it is affected by ground construction when used on a mobile basis, and the inability to monitor the air quality above the cavern due to height limitations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device for the construction environment of a storage power station cavern, comprising a plate, with hanging rods on both sides of the top of the plate, expansion bolts at the top of the hanging rods, sliding grooves on both side walls of the plate, a sliding block at the bottom of the plate, a first forward and reverse motor and a second forward and reverse motor sequentially installed on one side wall of the sliding block from bottom to top, a rope drum at the output end of the first forward and reverse motor, a steel wire rope wound around the outside of the rope drum, a bottom box fixedly connected to the end of the steel wire rope, an air quality monitoring mechanism installed inside the bottom box, a gear at the output end of the second forward and reverse motor, and a rack at the bottom of the plate.

[0006] Preferably, the boom is fixedly installed on the top of the energy storage power station cavern by expansion bolts, and the flat plate is fixedly connected to the energy storage power station cavern by the boom.

[0007] Preferably, the front of the plate has an opening, and the back of the plate has an insertion block. The insertion block on the back of the plate engages with the opening on the front of another plate.

[0008] Preferably, the top of the sliding block has a notch, and a roller is provided on the top of the inner side of the notch. The sliding block is slidably connected to the groove through the roller.

[0009] Preferably, the gear meshes with the rack, and the sliding block is slidably connected to the plate via the gear.

[0010] Preferably, a controller is provided at the bottom of the inner side of the sliding block, and the controller is electrically connected to the first forward and reverse motor and the second forward and reverse motor respectively.

[0011] Preferably, a through hole is provided in the middle of the bottom end of the sliding block, and the wire rope is movably connected to the sliding block through the through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The environmental monitoring equipment for the construction of the storage power station cavern is designed with a boom, plate, sliding block, gear and rack, which allows the monitoring equipment to be installed on the top of the inside of the cavern without occupying the ground space of the cavern. At the same time, the equipment is not likely to interfere with the construction on the cavern floor during the process of moving and using it, and it will not be affected by the ground construction facilities, making it easier to move and use the monitoring equipment in the cavern.

[0014] 2. The environmental monitoring equipment for the construction of the cavern of this pumped storage power station, through the installation of a first forward and reverse motor, a rope drum, a wire rope, and a base box, allows the base box to be raised and lowered below the sliding block. This enables the air quality monitoring mechanism inside the base box to be adjusted to a suitable height above the cavern according to the monitoring needs, thereby reducing the height restrictions on the monitoring equipment and making it more convenient for the monitoring equipment to monitor the air quality at different heights above the cavern.

[0023] like Figures 1 to 4As shown, the environmental monitoring equipment for the construction of the power station cavern in this embodiment includes a plate 3. The plate 3 has an "I"-shaped cross-section, which has good load-bearing capacity. Hanging rods 2 are installed on both sides of the top of the plate 3. The hanging rods 2 are used to suspend the plate 3 on the top of the power station cavern. Expansion bolts 1 are installed at the top of the hanging rods 2. Sliding grooves 5 are provided on both side walls of the plate 3. The sliding grooves 5 are used for sliding blocks 6 to slide on the plate 3. Sliding blocks 6 are provided at the bottom of the plate 3. The sliding blocks 6 drive the bottom-suspended base box 7 to slide on the plate 3. A first forward / reverse motor 8 and a second forward / reverse motor 9 are installed sequentially from bottom to top on one side wall of the sliding block 6. The output of the first forward / reverse motor 8... A rope drum 15 is provided at one end, and a steel wire rope 17 is wound around the outside of the rope drum 15. The end of the steel wire rope 17 is fixedly connected to a bottom box 7. Ventilation openings are provided on the front and back of the bottom box 7, so that air can enter the bottom box 7 and be monitored by the air quality monitoring mechanism 18 inside the bottom box 7. The air quality monitoring mechanism 18 is installed inside the bottom box 7. The air quality monitoring mechanism 18 includes an electrochemical sensor for monitoring the dust and oxygen content in the air, which is used to monitor the dust and oxygen concentration above the cavern. A gear 14 is provided at the output end of the second forward and reverse motor 9, and a rack 13 is provided at the bottom end of the plate 3. The gear 14 can mesh with the rack 13 to rotate, thereby realizing the sliding block 6 sliding along the plate 3.

[0024] Specifically, the boom 2 is fixedly installed on the top of the storage power station cavern 11 by expansion bolts 1, and the plate 3 is fixedly connected to the storage power station cavern 11 by the boom 2, so that the plate 3 and the auxiliary structure at the bottom of the plate 3 can slide on the top of the storage power station cavern, thereby realizing the movement of this monitoring equipment in the cavern.

[0025] Furthermore, the front of the plate 3 is provided with an insertion port 4, and the back of the plate 3 is provided with an insertion block 10. The insertion block 10 on the back of the plate 3 engages with the insertion port 4 on the front of another plate 3, so that multiple plates 3 can be connected end to end to form a long track, which facilitates the subsequent long-distance movement of the sliding block 6 in the cave and expands the monitoring range of this monitoring device.

[0026] Furthermore, the top of the sliding block 6 is provided with a notch 19, and a roller 12 is provided on the top of the inner side of the notch 19. The sliding block 6 is slidably connected to the slide groove 5 through the roller 12. The function of the notch 19 is to allow the sliding block 6 to slide against the bottom of the plate 3, thereby realizing the movement of the sliding block 6 on the plate 3.

[0027] Furthermore, gear 14 is meshed with rack 13, and sliding block 6 is slidably connected to plate 3 via gear 14. Gear 14 meshes with rack 13 and rolls, which can cause sliding block 6 to slide along the bottom of plate 3, thereby enabling air quality monitoring mechanism 18 in bottom box 7 to move along plate 3 via sliding block 6.

[0028] Furthermore, a controller 16 is provided at the bottom of the inner side of the sliding block 6. The controller 16 is electrically connected to the first forward and reverse motor 8 and the second forward and reverse motor 9 respectively. The function of the controller 16 is to control the forward and reverse rotation of the first forward and reverse motor 8 and the second forward and reverse motor 9, thereby realizing the winding of the wire rope 17 and the back and forth sliding of the sliding block 6.

[0029] Furthermore, a through hole 20 is provided in the middle of the bottom end of the sliding block 6. The steel wire rope 17 is movably connected to the sliding block 6 through the through hole 20. The function of the steel wire rope 17 is to keep the bottom box 7 connected to the sliding block 6, and at the same time, to allow the air quality monitoring mechanism 18 inside the bottom box 7 to be adjusted to a suitable height above the cavern by lifting and lowering, thereby facilitating the monitoring of air quality at different heights inside the cavern 11 of the energy storage power station.

[0030] The usage method of this embodiment is as follows: When using the construction environment monitoring equipment for the storage power station cavern 11, the hoisting rod 2 needs to be connected by the expansion bolt 1 driven into the top of the storage power station cavern 11, so that the plate 3 is fixed to the top of the empty space inside the storage power station cavern 11 by the hoisting rod 2. Then, the sliding block 6 is connected to the external power supply, and then the controller 16 controls the second forward and reverse motor 9 to rotate in the forward direction, so that the second forward and reverse motor 9 drives the gear 14 to rotate, so that the gear 14 meshes with the rack 13 at the bottom of the plate 3 to rotate, so that the sliding block 6 moves forward along the sliding grooves 5 on both sides of the plate 3 through the roller 12. As the cavern is advanced, the insertion port 4 on the front of the plate 3 can be connected to the insertion block 10 on the back of the plate 3 that has been fixed in the upper part of the cavern. The docking allows the flat plate 3 to be connected into a long track, enabling the sliding block 6 to move continuously along the connected flat plate 3 into the depth of the cavern. When the second forward and reverse motor 9 is controlled by the controller 16 to rotate in the opposite direction, the sliding block 6 can slide back along the flat plate 3, allowing the sliding block 6 to drive the bottom box 7 to retract to a suitable position. When it is necessary to monitor the air quality at different heights inside the cavern 11 of the energy storage power station, the controller 16 will control the first forward and reverse motor 8 to start, causing the first forward and reverse motor 8 to drive the rope drum 15 to rotate, causing the rope drum 15 to release the wire rope 17, allowing the bottom box 7 at the end of the wire rope 17 and the air quality monitoring mechanism 18 inside the bottom box 7 to be lowered to a suitable height above the cavern.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
