[0028] This embodiment discloses an underwater repair isolation device for the pool wall of an underground water purification plant and a water-carrying repair construction method thereof, which are used to solve the problems existing in the prior art.

[0029] Embodiment 1 like Figure 1 As shown, this embodiment provides an underwater repair isolation device for the pool wall of an underground water purification plant, including a vacuum suction cup system 1, an isolation chamber system, an intelligent monitoring system, a pumping device and a monitoring terminal 34.

[0030] Among them, the isolation chamber system includes an isolation chamber 2, and the intelligent monitoring system includes a harmful gas monitor 31. The top surface of the isolation chamber 2 and the side facing the pool wall of the underground water treatment plant are hollowed out. The suction cup part of the vacuum suction cup system 1 is arranged on the outer edge of the hollow side of the isolation chamber 2, so that the isolation chamber 2 can be adsorbed on the pool wall of the underground water treatment plant (the pool wall to be repaired). Specifically, the negative pressure and filtration part of the vacuum suction cup system 1 are arranged outside the treatment pool of the underground water treatment plant, and the negative pressure and filtration part of the vacuum suction cup system 1 are connected to the suction cup part of the vacuum suction cup system 1. In this embodiment, two groups of harmful gas monitors 31 are provided, both of which are located inside the isolation chamber 2 and separated up and down to improve the monitoring accuracy. The harmful gas monitor 31 is wirelessly connected to the monitoring terminal 34 to transmit the monitored harmful gas content data to the monitoring terminal 34. The pumping end of the pumping device is arranged inside the isolation chamber 2 for extracting water from the isolation chamber 2.

[0031] Through the above technical scheme, the isolation chamber 2 of the present invention can be adsorbed on the pool wall to be repaired through the vacuum suction cup system 1, and the water in the isolation chamber 2 can be discharged through the pumping device. During this period, the harmful gas monitor 31 is used to monitor the toxic gas content in the isolation chamber 2, so as to create a smaller water-free and non-toxic space, and provide it to construction personnel to repair the pool wall to be repaired, so that the construction personnel are isolated from the sewage in the pool body, thereby ensuring the life safety of the construction personnel.

[0032] like Figure 2 As shown, the isolation bin 2 system also includes a sling 22, a ladder 23, a plexiglass plate 24, a lighting device 25 and a roller device 26. The main body of the isolation bin 2 is a bin frame 21 with six sides. In the present embodiment, the size of the isolation bin 2 is 1.5m×2m×2.5m (length×width×height), and it is welded with a Q235 steel plate with a thickness of 20mm. A plurality of slings 22 are fixedly connected to the top of the isolation bin 2 to facilitate the lifting of the isolation bin 2 in the pool to be repaired. In the present embodiment, the slings 22 are made of steel strands. The ladder 23 is vertically arranged on the inner wall of the isolation bin 2 for construction personnel to enter and exit. The lighting device 25 is composed of 3 groups of rechargeable LED light groups, which are located on the upper side of the interior of the isolation bin 2 for construction lighting to improve the visibility of the construction environment. In this embodiment, the thickness of the organic glass plate 24 is 20 mm, and it is arranged opposite to the hollow surface of the isolation chamber 2, and the organic glass plate 24 is connected to the metal frame of the isolation chamber 2 by a water stop gasket and a stainless steel bolt. The design of the organic glass plate 24 is conducive to the construction personnel to confirm from the outside whether the water in the isolation chamber 2 is drained. The roller device 26 is arranged at the bottom of the isolation chamber 2. When the pool to be repaired is shallow, the isolation chamber 2 can be moved by pushing the isolation chamber 2.

[0033] like Figure 1 , Figure 3 and Figure 4As shown in the figure, the suction cup part of the vacuum suction cup system 1 includes a "U"-shaped suction cup 11 and a suction cup frame, and its negative pressure and filtration part includes a vacuum pump 15 and a vacuum filtration barrel 16. Among them, the vacuum pump 15 is used to provide negative pressure, and the vacuum filtration barrel 16 is used to filter out moisture or gaseous colloidal substances so that the vacuum pump 15 can operate stably. The suction cup frame is fixedly connected to the edge of the hollow side of the isolation chamber 2. The "U"-shaped suction cup 11 is arranged inside the suction cup frame with the suction cup side facing the wall of the underground water purification plant pool, and the "U"-shaped suction cup 11 is connected to the negative pressure absorption end of the vacuum pump 15 through the vacuum filtration barrel 16.

[0034] Through the above technical solution, the isolation chamber 2 can be tightly adsorbed on the pool wall to be repaired, and moisture or impurities in the flow channel 14 during the adsorption process can be filtered out.

[0035] Furthermore, the vacuum suction cup system 1 further includes a plurality of circular suction cups 12 and a plurality of adsorption holes 13. The suction cup part of the vacuum suction cup system 1 further includes a plurality of circular suction cups 12; the suction ports of the circular suction cups 12 face the wall of the underground water purification plant pool; a plurality of circular suction cups 12 are arranged inside the suction cup frame, the "U"-shaped suction cup 11 is provided with an inner and outer double layer, and the circular suction cups 12 are located in the interlayer of the "U"-shaped suction cup 11; both the circular suction cups 12 and the "U"-shaped suction cup 11 are provided with adsorption holes 13. The flow channels 14 between the adsorption holes 13 communicate with each other and crisscross, showing a "field" shape.

[0036] Compared with the prior art, the present invention improves the vacuum suction cup system 1. The multi-layer suction cup design such as the "U"-shaped suction cup 11, the circular suction cup 12 and the adsorption holes 13 can improve the water isolation and adsorption effects of the isolation chamber 2.

[0037] Preferably, the above "U"-shaped suction cup 11 and circular suction cup 12 are made of nitrile rubber (NBR). For the complex underwater environment of the sewage treatment plant, it has excellent toughness, wear resistance, aging resistance, oil resistance, acid and alkali resistance and water resistance.

[0038] In this embodiment, the width of the "U"-shaped suction cup 11 is 40 mm, and the thickness at the highest point is 5 mm. The cross-sectional shape of the "U"-shaped suction cup 11 is arc-shaped, the radius is 45 mm, and the arc length is 40 mm. The diameter of the circular suction cup is 100 mm, and the thickness is 5 mm. The adsorption hole 13 is circular, and its diameter is 20 mm.

[0039] Furthermore, the intelligent monitoring system further includes a vacuum pressure sensor 33 and a stress sensor 32. The pressure monitoring end of the vacuum pressure sensor 33 is arranged inside the vacuum filtration barrel 16, and the vacuum pressure sensor 33 is wirelessly communicatively connected to the monitoring terminal 34. The stress sensor 32 is used to sense the tension of the sling 22 and is wirelessly communicatively connected to the monitoring terminal 34.

[0040] Through the above technical solution, the device of the present invention can monitor the tension and vacuum degree of the sling 22 in real time to assist in determining whether the operation in the isolation chamber 2 meets the safety standards.

[0041] Embodiment 2 like Figure 5 As shown, this embodiment discloses a construction method for repairing the pool wall of an underground water purification plant with water, the method adopts the underwater repair isolation device for the pool wall of the underground water purification plant recorded in the first embodiment, and the method of the present invention comprises: S10: Use a long-handled tool to preliminarily clean the attachments on the pool wall to be repaired.

[0042] Specifically, a long-handled tool is used to preliminarily clean and break up the attachments around the pool wall to be repaired, so as to ensure that the isolation chamber fits tightly with the pool wall. In addition, step S10 can also prevent blocky colloids or impurities from clogging the flow channel in the vacuum suction cup system.

[0043] S20: hoist the isolation chamber to the pool wall to be repaired, so that the hollow side wall of the isolation chamber is in close contact with the pool wall to be repaired.

[0044] Specifically, by adjusting the length of the four steel strands, the box is leveled for easy construction. Then, the isolation chamber is hoisted by the water purification workshop crane and hoisted to the water surface above the repair site, keeping a distance of 5 cm from the pool wall, and slowly lowering the isolation chamber to keep the liquid level inside the chamber level with the liquid level outside the chamber. After reaching the specified height, the isolation chamber is slowly moved by the crane to be close to the pool wall.

[0045] S30: Turn on the negative pressure and filtering parts of the vacuum suction cup system until the vacuum degree reaches a preset value, and then turn on the water pump to drain the water in the isolation chamber.

[0046] In this embodiment, the negative pressure and filtering part of the vacuum suction cup system and the water pump continue to operate after being turned on.

[0047] Specifically, after the vacuum degree reaches the preset value, the isolation chamber will be tightly adsorbed to the wall of the pool to be repaired, and the water inside and outside the isolation chamber will be isolated from each other. At this time, a water pump will be used to discharge the water in the isolation chamber.

[0048] S40: When the liquid level in the isolation chamber drops to the point where the pool wall to be repaired is completely exposed, a high-pressure water gun is used to flush the pool wall to be repaired.

[0049] It should be noted that the discharge pump continues to run during the flushing with a high-pressure water gun.

[0050] S50: After the water in the isolation chamber is completely drained, determine whether the harmful gas data, sling stress, and vacuum degree obtained by the preset sensor meet the preset standards; if so, execute step S60, if not, return to step S40.

[0051] Specifically, after the water in the isolation chamber is drained, the harmful gas content is monitored using a harmful gas monitor, the stress of the sling is monitored using a stress sensor, and the vacuum pressure is monitored using a vacuum pressure sensor. At the same time, water mist spraying and ventilation are performed in the chamber to remove harmful gases, and the crane is slowly raised or lowered to make the stress of the sling meet the set value. During this period, vacuuming is continuously performed to maintain a stable vacuum degree. If all indicators are tested to be qualified, the operator will repair the chamber wall.

[0052] S60: Inform the operating personnel to enter the isolation chamber to repair the pool wall to be repaired.

[0053] It should be noted that after the repair work is completed, wait until the construction workers leave the isolation chamber, then turn off the vacuum pump, then slowly lift the isolation chamber off the horizontal surface, then rinse the isolation chamber with a high-pressure water gun, and finally hoist it to the ground, and clean the isolation chamber and the flow channel in the vacuum suction cup in preparation for the next use.

[0054] Through the above technical solution, the device of the present invention can be put into use efficiently and the life safety of construction workers can be guaranteed.

[0055] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
