DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a toxic gas monitoring device for power distribution environment monitoring as shown in Figures 1 to 8, including a water receiving pipe 1, a first connecting pipe 2 is inserted through the top of the water receiving pipe 1, a pipe cover 3 is installed on the top of the first connecting pipe 2, a first sleeve 4 is inserted through the top center of the pipe cover 3, and the first sleeve 4 is located at the bottom of the pipe cover 3 and is rotatably sleeved with a first fixing ring, a plurality of first fixing rods 5 are fixedly connected between the first fixing ring and the inner wall of the first connecting pipe 2, a first rotating shaft 6 is inserted through the first sleeve 4 for sliding movement, and an impeller 7 is installed at the bottom end of the first rotating shaft 6. In the initial state, the impeller 7 is completely located in the first connecting pipe 2, and the bottom of the first connecting pipe 2 protrudes downward near the water inlet direction of the water receiving pipe 1, and the height of the protruding part is equal to the height of the impeller 7, and the circumference of the downward protruding part of the first connecting pipe 2 is equal to one-fourth of the circumference of the impeller 7.

[0030] A collecting box 8 is provided on the front side of the water receiving pipe 1, and the collecting box 8 is filled with absorbent. A partition 9 is vertically arranged inside the collecting box 8. The top of the partition 9 and the front and rear sides of the partition 9 are respectively fixedly connected to the top and front and rear inner walls of the collecting box 8, and the bottom of the partition 9 is higher than the liquid level of the absorbent. A box cover 10 is installed on the top of the collecting box 8. A second connecting pipe 11 is inserted through the top of the box cover 10. An exhaust hole is opened through the top of the box cover 10. The exhaust hole is located on the side of the partition 9 away from the first connecting pipe 2, and a filter box 12 is installed on the top of the exhaust hole. An air suction component 13 is provided in the second connecting pipe 11, and a transmission component 14 is connected between the air suction component 13 and the first rotating shaft 6. A detector 15 is installed on the top of the transmission component 14, and the detector 15 has a built-in wireless sending module. A controller 16 is provided at the bottom of the detector 15, and a mounting plate is connected to the bottom of the controller 16. The mounting plate is fixedly connected to the side of the collecting box 8 close to the water receiving pipe 1, and a data line 17 is electrically connected between the controller 16 and the detector 15.

[0031] Before use, connect the water pipe 1 to the pumping pipe in the pumped storage hydropower station. During use, when the detector 15 detects that the toxic and harmful gases in the external environment exceed the standard, the detector 15 can control the transmission component 14 to move downward through the controller 16. At the same time, the wireless sending module in the detector 15 can also send an alarm to the maintenance personnel, thereby reminding the maintenance personnel to deal with it in time.

[0032] As the transmission assembly 14 moves downward, the transmission assembly 14 can drive the first rotating shaft 6 and the suction assembly 13 to move downward. As the first rotating shaft 6 moves downward, the impeller 7 originally located in the first connecting pipe 2 can gradually extend from the bottom of the first connecting pipe 2. At this time, the water flowing through the water receiving pipe 1 can impact the impeller 7. At this time, since the downward protruding part of the bottom of the first connecting pipe 2 can block a quarter of the impeller 7, the water flow can only push the impeller 7 to rotate through the unblocked part of the impeller 7, thereby realizing the unidirectional rotation of the impeller 7.

[0033] As the impeller 7 rotates, the impeller 7 can drive the first rotating shaft 6 and the first sleeve 4 to rotate together. As the first rotating shaft 6 rotates, the first rotating shaft 6 can drive the suction component 13 in the second connecting pipe 11 to work through the transmission component 14, thereby sucking the toxic and harmful gases in the external environment into the collection box 8 through the second connecting pipe 11. Subsequently, the toxic and harmful gases entering the collection box 8 can be blown onto the surface of the absorbent under the action of the suction component 13, so that the toxic and harmful gases can be absorbed by the absorbent.

[0034] The gas that enters the collection box 8 can then pass through the bottom of the partition 9 and enter the side of the partition 9 away from the second connecting pipe 11. The gas can then enter the filter box 12 through the exhaust hole, so that the remaining toxic and harmful gases can be further absorbed by the filter box 12, thereby realizing the absorption and treatment of toxic and harmful gases in the sealed environment, and avoiding toxic and harmful gases from causing harm to the health of maintenance personnel.

[0035] As the suction component 13 continues to work, when the content of toxic and harmful gases in the external environment decreases, the detector 15 can control the transmission component 14 to reset through the controller 16, so that the impeller 7 re-enters the first connecting pipe 2, thereby reducing the blocking effect of the impeller 7 on the water flow in the docking water pipe 1.

[0036] As shown in Figures 1 to 4, the air intake assembly 13 includes a second sleeve 131, and the second connecting pipe 11 is vertically inserted into the second connecting pipe 11. The second sleeve 131 is rotatably sleeved with a second fixing ring near the top and bottom, and a plurality of second fixing rods 132 are fixedly connected between the second fixing ring and the inner wall of the second connecting pipe 11. The part of the second sleeve 131 located between the two second fixing rings is installed with two first exhaust fans 133, and the blowing directions of the two first exhaust fans 133 are both downward, and a second rotating shaft 134 is slidably inserted through the second sleeve 131.

[0037] When the detector 15 detects that the content of toxic and harmful gases in the external environment exceeds the standard, the detector 15 can control the transmission component 14 to move downward through the controller 16. As the transmission component 14 moves downward, the first rotating shaft 6 and the second rotating shaft 134 gradually move downward. As the first rotating shaft 6 gradually moves downward, the impeller 7 extends from the bottom of the first connecting pipe 2 driven by the first rotating shaft 6. At this time, the water flowing through the water receiving pipe 1 can drive the impeller 7 to rotate. As the impeller 7 rotates, the first rotating shaft 6 and the first sleeve 4 also start to rotate driven by the impeller 7, and the second rotating shaft 134 and the second sleeve 131 can rotate together driven by the transmission component 14, and then the toxic and harmful gases in the outside world are sucked into the collection box 8 through the second connecting pipe 11 through the two first exhaust fans 133 on the second sleeve 131 and absorbed by the absorbent, thereby preventing the toxic and harmful gases from causing harm to the health of the maintenance personnel.

[0038] As shown in Figures 1 and 2, the transmission assembly 14 includes a connecting plate 141, which is rotatably sleeved on the top of the first rotating shaft 6 and the second rotating shaft 134. An electric telescopic rod 142 is vertically fixedly connected between the bottom of the connecting plate 141 and the top of the mounting plate, and the electric telescopic rod 142 is electrically connected to the controller 16. A transmission belt 143 is connected between the top of the first rotating shaft 6 and the second rotating shaft 134.

[0039] In the initial state, the electric telescopic rod 142 is in an extended state. At this time, the impeller 7 located on the first rotating shaft 6 can be completely located in the first connecting tube 2. When the detector 15 detects that the content of toxic and harmful gases in the external environment exceeds the standard, the detector 15 can control the electric telescopic rod 142 to shorten through the controller 16. As the electric telescopic rod 142 shortens, the first rotating shaft 6 and the second rotating shaft 134 gradually move downward under the drive of the connecting plate 141.

[0040] As the first rotating shaft 6 gradually moves downward, the impeller 7 extends from the bottom of the first connecting pipe 2 driven by the first rotating shaft 6. At this time, the water flowing through the water receiving pipe 1 can drive the impeller 7 to rotate. As the impeller 7 rotates, the first rotating shaft 6 and the first sleeve 4 also start to rotate driven by the impeller 7, and the second rotating shaft 134 and the second sleeve 131 can rotate together driven by the transmission belt 143, and then the two first exhaust fans 133 on the second sleeve 131 suck the toxic and harmful gases in the outside world into the collection box 8 through the second connecting pipe 11 and are absorbed by the absorbent, thereby preventing the toxic and harmful gases from causing harm to the health of the maintenance personnel.

[0041] As shown in Figures 1, 2 and 8, an air inlet is provided at the bottom of the filter box 12. A multi-layer activated carbon filter 18 is vertically arranged inside the filter box 12. The filter diameter of the multi-layer activated carbon filter 18 gradually decreases away from the air inlet. A through hole is formed on the side of the filter box 12 away from the second connecting pipe 11.

[0042] When the gas entering the collection box 8 enters the filter box 12 through the exhaust hole and the air inlet, the multi-layer activated carbon filter 18 inside the filter box 12 can further absorb the residual toxic and harmful gases, thereby achieving the purpose of reducing the content of toxic and harmful gases in the external environment.

[0043] As shown in Figures 3, 4 and 7, a sealing plate 19 is fixedly sleeved on the bottom end of the second rotating shaft 134, and in the initial state, the sealing plate 19 is tightly attached to the bottom of the second connecting tube 11. The thickness of the sealing plate 19 gradually becomes thicker from the edge to the center, and an annular sealing groove matching the bottom of the second connecting tube 11 is opened at the top edge of the sealing plate 19.

[0044] By providing the sealing plate 19, in the initial state, the sealing plate 19 can maintain close contact with the bottom of the second connecting pipe 11, and the bottom of the second connecting pipe 11 is sealed through the annular sealing groove, thereby reducing the volatilization of the absorbent into the outside air and preventing dust from falling into the absorbent;

[0045] When the detector 15 detects that the content of toxic and harmful gases in the external environment exceeds the standard, the detector 15 can control the electric telescopic rod 142 to shorten through the controller 16. As the electric telescopic rod 142 shortens, the first rotating shaft 6 and the second rotating shaft 134 gradually move downward under the drive of the connecting plate 141. As the second rotating shaft 134 gradually moves downward, the sealing plate 19 can be gradually separated from the bottom of the second connecting pipe 11 under the drive of the second rotating shaft 134, so that the bottom of the second connecting pipe 11 is gradually opened. At this time, the toxic and harmful gases in the external air can be sucked into the collection box 8 under the action of the first exhaust fan 133 and absorbed by the absorbent.

[0046] In addition, when the toxic and harmful gas is blown onto the top of the sealing plate 19 under the action of the first exhaust fan 133, the top of the sealing plate 19 can evenly transport the toxic and harmful gas to the surrounding area, thereby increasing the contact area between the toxic and harmful gas and the absorbent and improving the absorption efficiency of the absorbent.

[0047] As shown in Figures 3 and 4, a stirring shaft 20 is slidably inserted into the bottom of the second rotating shaft 134, and the bottom end of the stirring shaft 20 is rotatably connected to the bottom inner wall of the collecting box 8. A plurality of stirring rods 21 are vertically fixedly connected to the surface of the stirring shaft 20 near the bottom end.

[0048] By providing a stirring shaft 20, during the rotation of the second rotating shaft 134, the stirring shaft 20 can rotate together with the second rotating shaft 134, so that the absorbent in the collection box 8 is stirred by the stirring rod 21 on the surface of the stirring shaft 20, thereby accelerating the absorption rate of the absorbent to toxic and harmful gases.

[0049] As shown in Figures 1 to 4, a second exhaust fan 22 is installed on the top of the second rotating shaft 134. The diameter of the second exhaust fan 22 is larger than the diameter of the first exhaust fan 133, and the blowing direction of the second exhaust fan 22 is downward. An annular guide cover 23 is fixedly connected to the top edge of the second connecting pipe 11. The opening diameter of the guide cover 23 gradually decreases from top to bottom, and the top opening diameter of the guide cover 23 is larger than the diameter of the second exhaust fan 22.

[0050] Since the air flow is poor in a relatively closed environment, a second exhaust fan 22 is installed on the top of the second rotating shaft 134. When the first rotating shaft 6 drives the second rotating shaft 134 to rotate through the transmission belt 143 under the action of the impeller 7, the second exhaust fan 22 can blow the gas in the external environment downward under the action of the second rotating shaft 134, thereby accelerating the flow speed of the gas in the external environment. In the process of the gas flowing downward, when the gas encounters the guide cover 23, the gas can enter the second connecting pipe 11 under the action of the guide cover 23, and then the gas entering the second connecting pipe 11 can enter the collection box 8 under the action of the first exhaust fan 133 and contact the absorbent in the collection box 8, so as to be absorbed by the absorbent, thereby improving the absorbent's absorption efficiency of toxic and harmful gases in the external environment.

[0051] The technical effects and advantages of the present invention are as follows:

[0052] 1. The present invention is provided with an air suction component. When the detector detects that the content of toxic and harmful gases exceeds the standard, the detector can control the electric telescopic rod to shorten through the controller, thereby driving the first rotating shaft and the second rotating shaft to move downward through the connecting plate, so that the impeller is driven by the first rotating shaft to extend from the bottom of the first connecting pipe. At this time, water flowing through the water receiving pipe can drive the impeller to rotate the first rotating shaft, and the second rotating shaft can drive the two first exhaust fans to rotate under the action of the transmission belt, thereby sucking the toxic and harmful gases in the outside world into the collection box and being absorbed by the absorbent;

[0053] 2. The present invention is provided with a stirring shaft. During the rotation of the second rotating shaft, the stirring shaft can rotate together with the second rotating shaft, thereby stirring the absorbent in the collection box through the stirring rod on the surface of the stirring shaft, thereby accelerating the absorption rate of toxic and harmful gases by the absorbent;

[0054] 3. The present invention installs a second exhaust fan on the top of the second rotating shaft. When the second rotating shaft rotates, the second exhaust fan can blow the gas in the external environment downward under the action of the second rotating shaft, thereby accelerating the flow speed of the gas in the external environment. In the process of the gas flowing downward, when the gas encounters the guide cover, the gas can enter the second connecting pipe under the action of the guide cover, and then the gas entering the second connecting pipe can enter the collection box under the action of the first exhaust fan and contact with the absorbent in the collection box, so as to be absorbed by the absorbent, thereby improving the absorption efficiency of the absorbent for toxic and harmful gases in the external environment.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
