Description

Technical Field

[0001] The present invention relates to the technical field of maintenance of hydropower station structures, and particularly relates to a maintenance tooling and method for quickly blocking water and rush repair of drainage ditches. Background Art

[0002] In large hydropower stations, the main transformer cooling water is usually discharged through drainage ditches. However, due to the high water level in the drainage ditches, it is difficult to clean the sediment and other sundries at the bottom and to repair the equipment such as the reserved pipelines inside the drainage ditches. Traditional maintenance methods are often affected by water flow, and the construction environment is harsh, resulting in low operation efficiency, slow construction progress, and certain safety hazards.

[0003] Currently, for the cleaning of drainage ditches or equipment maintenance, mainly personnel wear safety belts to carry out wading operations. Workers need to wear safety belts and enter the drainage ditches with a relatively high water level for operations. This approach not only increases the physical consumption of personnel but also brings safety hazards such as slipping and drowning. Summary of the Invention

This maintenance tooling can completely isolate and drain a local area of the drainage ditch to form a dry construction environment, ensuring that the construction process is not affected by water flow, thereby effectively improving the working environment of operators, accelerating the construction progress, and improving work efficiency.

After the water blocking air bags are inflated, they are in contact and sealed with the two side walls and the bottom plate of the drainage ditch. The top end of the water blocking plate is connected to the lifting device.

[0008] Preferably, the water retaining airbag is connected to an inflation system, and the inflation system uses a blower, which is connected to the water retaining airbag through an air pipe and a valve.

[0028] Embodiment 1: Refer to Figures 1 - 3 , a maintenance tool for quickly blocking water and repairing a drainage ditch, including a maintenance platform 1. On both sides of the bottom of the maintenance platform 1, a water-blocking device 2 is installed. The water-blocking device 2 is in sealing contact with the inner walls of the upstream and downstream of the drainage ditch to achieve water blocking inside the maintenance platform 1. The top end of the water-blocking device 2 is connected to a lifting device 3, the lifting device 3 is fixed to the top end of the maintenance platform 1, and a lifting device 4 is installed at the bottom end of the platform roof 104 of the maintenance platform 1. A drainage device 5 for draining water is mounted on the side of the maintenance platform 1. The lifting device 3, the lifting device 4, and the drainage device 5 are connected to a control cabinet 6, and the control cabinet 6 is fixed to the maintenance platform 1. By integrating the water-blocking device, the lifting device, the drainage device, and the control cabinet, the present invention realizes the automated operations of quickly blocking water, draining water, and dredging the drainage ditch. Compared with traditional manual operations, it not only improves the efficiency and safety of the drainage ditch repair and sump dredging operations, but also reduces the construction cost through intelligent and integrated design, and has significant technical and economic value.

[0029] Furthermore, the maintenance platform 1 includes a frame main body 101. Universal wheels 103 are installed at the bottom end of the frame main body 101, a fence door 102 is installed on the lower side surface of the frame main body 101, and a platform roof 104 is fixed to the top end of the frame main body 101. The maintenance platform 1 can be used to carry the entire maintenance tool, thereby facilitating the movement of the entire maintenance tool. The universal wheels 103 facilitate the overall movement of the entire frame main body 101, and the fence door 102 provides a protective effect.

[0030] Furthermore, the water-blocking device 2 includes water-blocking plates 201. Two water-blocking plates 201 are respectively slidably installed on the opposite sides of the frame main body 101 and are located at the upstream and downstream of the drainage ditch. Water-blocking airbags 202 are arranged and installed on both side edges and the bottom edge of the water-blocking plates 201. After being inflated, the water-blocking airbags 202 are in contact with and sealed to the side walls and the bottom plate of the drainage ditch. The top end of the water-blocking plate 201 is connected to the lifting device 3. Through the above-mentioned water-blocking device 2, it can be used to block water at the upstream and downstream of the drainage ditch during subsequent maintenance, so as to form a water-free environment. During the specific water-blocking process, the water-blocking airbags 202 play a very good role in sealing and blocking water.

[0031] Further, the water retaining airbag 202 is connected to an inflation system. The inflation system uses a blower 203, and the blower 203 is connected to the water retaining airbag 202 through an air pipe and a valve. Through the above inflation system, it is convenient to inflate the water retaining airbag 202, so as to achieve the subsequent reliable water blocking and sealing purpose. During the inflation process, by rotating the blower 203 forward, the effect of blowing air is achieved. When exhaust is required, the blower 203 rotates in reverse.

The lifting device 3 can be used to lift and lower the water baffle 201, and then lower it into the drainage ditch, so as to achieve the blocking of the drainage ditch. During the specific working process, when water blocking is required, the hydraulic pump station 302 is started, the hydraulic pump station 302 drives the hydraulic cylinder 301, and the hydraulic cylinder 301 drives the water baffle 201 to lower, and then extends into the drainage ditch.

[0033] Further, the lifting device 4 includes a winch 401. The winch 401 is fixedly installed at the bottom end of the platform top plate 104. A winch rope is wound around the drum of the winch 401, and a hook 402 is connected to the end of the winch rope. The lifting device 4 facilitates the opening or closing of the drainage ditch cover plate 8. During the construction process, the drainage ditch cover plate 8 is lifted by the lifting device 4, and the drainage ditch cover plate 8 is moved to a side position by moving the maintenance platform 1.

[0034] Further, the drainage device 5 includes a box body 501 fixedly installed on the side wall of the frame main body 101. A drainage pump 502 is placed inside the box body 501, and a drainage pipe 503 is connected to the drainage pump 502. The drainage device 5 facilitates the drainage of the water in the drainage ditch after water blocking is completed. During the drainage process, the drainage pump 502 is connected to the drainage pipe 502, and the drainage pump 502 is placed at the bottom of the drainage ditch 7 by the lifting device 4, and the drainage pump 502 is started to drain water.

[0035] Further, there is at least one group of hydraulic cylinders 301 at the top of the same water baffle 201. Through the above arrangement, the stability of the lifting or lowering of the water baffle 201 is ensured.

[0036] Further, the hydraulic pump station 302 is connected to the hydraulic cylinder 301 through a hydraulic valve group and a hydraulic pipeline. Through the above hydraulic valve group, the automatic control of the hydraulic cylinder is facilitated.
