Description
Technical Field

[0002] In modern urban or rural construction, in order to effectively deal with the problems of rising river water levels and insufficient drainage after heavy rains, drainage stations are usually built. Drainage stations are usually connected to rivers and pipelines. When floods occur, the water level can be effectively controlled through drainage stations, and the floods can be discharged from residential areas to ensure that the water level is below the safe level.
[0003] In the current application of drainage stations, since the pumps used for drainage often need to be replaced and cleaned when working at full capacity, multiple pumps are usually configured in a drainage pump station. Generally, they are not all turned on at the same time, but are operated alternately.
[0004] This is because during the drainage process, due to the rising water level, a lot of debris will enter the river channel. During the drainage process of the pump, the presence of debris will not only cause blockage in the pump position, affecting the drainage effect, but also cause wear on the mechanical structure of the pump, affecting the service life of the pump. Therefore, in the current operation and maintenance of drainage pump stations, it is often necessary to configure buffer tanks and other measures. However, due to the high requirements for continuity during the operation of the pump, sometimes buffer tanks or conventional filtering methods are not effective. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] like Figure 1-5 As shown, a drainage station for preventing geological disasters in flood-prone areas after heavy rain is constructed on the basis of a reinforced concrete station base 1 next to a drainage system or river. An inlet confluence 2 and an outlet confluence 3 are provided on both sides of the station base 1 for confluence of influent and drainage.
[0031] At the same time, as a primary buffer device, a drainage buffer pool 4 is arranged on the station base 1. The two sides of the drainage buffer pool 4 are connected to the water inlet confluence 2 and the water outlet confluence 3. At least one prefabricated drainage pipe 5 is arranged on the side of the drainage buffer pool 4 connected to the water outlet confluence 3. According to the drainage flow demand, multiple prefabricated drainage pipes 5 are selected and arranged in parallel to connect the drainage buffer pool 4 with the water outlet return port.
[0032] A drainage pump group 6 is installed on the prefabricated drainage pipe 5, and the drainage pump group 6 is used as a power. The drainage pump group 6 is an axial flow submersible pump group. The drainage pump group 6 is installed on the pipe end of the prefabricated drainage pipe 5. The end of the prefabricated drainage pipe 5 is provided with a flange plate connected to the drainage pump group 6. The end of the drainage pump group 6 is provided with a protective mesh cage, which is used to further protect the drainage pump group 6 from the influence of solid impurities and discharge the water in the drainage buffer tank 4 through the prefabricated drainage pipe 5.
[0033] A control gate 91 is provided at the end of the prefabricated drainage pipe 5. The lifting control structure 9 of the control gate 91 is installed on the station base 1. The control gate 91 matches the end of the prefabricated drainage pipe 5. The control gate 91 can be used to control the switch of the prefabricated drainage pipe 5 and cooperate with the drainage pump group 6 to work.
[0034] A drainage filter 7 is provided on one side of the drainage buffer tank 4 near the water inlet confluence port 2. The drainage filter 7 is installed based on the station base 1 to filter the water entering the drainage buffer tank 4 from the water inlet return port.
[0035] Specifically, the drainage filter 7 is composed of a control housing 71 installed in the drainage buffer tank 4, a circulating water filter structure 72 connected to the control housing 71 for cleaning debris, and a feeding structure 73 installed on the station base 1 for cleaning the circulating water filter structure 72. Among them, the control housing 71 plays the role of coarse filtering and supporting, and is used to support the bottom end of the circulating water filter structure 72; while the circulating water filter structure 72 adopts a circulating working mode, which is used to finely filter the passing water body and separate solid impurities and sand; cooperate with the feeding structure 73 to separate the solid impurities and sand carried by the drainage filter 7, enhance the operation time of the circulating water filter structure 72, and ensure the smooth operation of the circulating water filter structure 72 for a long time, and then in the working process of the drainage pump group 6, reduce the impact of solid impurities on the drainage pump group 6, reduce the number of maintenance of the drainage pump group 6, and increase the operation time of a single drainage pump group 6, so as to improve the efficiency of drainage work.
[0036] Furthermore, the control housing 71 is a rectangular box, and the two sides of the control housing 71 are assembled on the ground of the station base 1 through a pair of lifting mechanisms 8. The height of the control housing 71 can be adjusted through the pair of lifting mechanisms 8, so that the control housing 71 can be hoisted to a high place for cleaning, and a matrix of filter sieve holes are provided on the side of the control housing 71 facing the prefabricated drainage pipe 5. The filter sieve holes can be used to coarsely filter the flowing water and intercept solid impurities to prevent solid impurities in the water flow from leaking through. The width of the control housing 71 matches the width of the drainage buffer tank 4, and can completely block the passage of solid impurities in the water flow.
[0037] The lifting mechanism 8 includes a pair of lifting guide rails 81, which are assembled on the side walls of the drainage buffer tank 4. A pair of guide grooves 82 are arranged on the outer side of the control housing 71, and the pair of guide grooves 82 match the pair of lifting guide rails 81. A pair of lifting chains 83 are installed on the pair of lifting guide rails 81, and the pair of lifting chains 83 are connected to both sides of the control housing 71. A pair of lifting chain cars 84 are arranged on both sides of the pair of lifting guide rails 81 and connected to the pair of lifting chains 83.
[0038] In the specific implementation process, a pair of lifting guide rails 81 are used to limit and guide the pair of guide grooves 82 on both sides of the control housing 71. During the lifting and lowering process of the control housing 71, the pair of lifting guide rails 81 are used to stabilize it, and then the pair of lifting chains 83 are retracted and unreeled by a pair of lifting chain cars 84. The control housing 71 can be driven up and down by the pair of lifting chains 83, thereby achieving the purpose of controlling the lifting and lowering of the control housing 71.
[0039] Furthermore, the circulating water filtering structure 72 is composed of an adjustable bracket 721 on the station base 1, a circulating salvage device 722 connected to the adjustable bracket 721, and a power assembly 723 for driving the circulating salvage device 722. In the specific implementation process, the adjustable bracket 721 is used to support the top of the circulating salvage device 722 and adjust the height and horizontal angle of the circulating salvage device 722, and the power assembly 723 provides the operating power of the circulating salvage device 722.
[0040] The adjustable bracket 721 includes a supporting frame 7211, the bottom end of the supporting frame 7211 is movably connected to a pair of movable seats 7212 assembled in the control housing 71, the middle section of the supporting frame 7211 is connected to a pair of adjustable telescopic rods 7213, and the bottom ends of the pair of adjustable telescopic rods 7213 are movably connected to the station base 1.
[0041] In the specific implementation process, the support frame 7211 is a rectangular frame, which is movably installed in the control housing 71 through a pair of movable seats 7212, and then movably connected to the middle section of the support frame 7211 through a pair of adjustable telescopic rods 7213, forming a rectangular frame that can be adjusted in pitch. The pair of adjustable telescopic rods 7213 adopts a threaded telescopic structure, and the outer shells of the pair of adjustable telescopic rods 7213 are rotated to complete the telescopic movement, thereby changing the position of the middle part of the support frame 7211, so that the support frame 7211 rotates with the movable seat 7212 as the axis.
[0042] The circulating salvage device 722 includes a fixed shaft 7221, which is assembled on a pair of movable seats 7212. A circulating roller 7222 is sleeved on the fixed shaft 7221. Another circulating roller 7222 is correspondingly arranged at the top of the supporting frame 7211. A circulating mesh plate 7223 is sleeved between the pair of circulating rollers 7222. A plurality of carrying plates 7224 are arranged in a linear array on the circulating mesh plate 7223. A plurality of filtering holes are opened on the circulating mesh plate 7223.
[0043] In the specific implementation process, the circulation roller 7222 is installed by the fixed shaft 7221. There are two circulation rollers 7222, one above and one below. The circulation mesh plate 7223 is supported by the circulation roller 7222. The circulation mesh plate 7223 circulates under the drive of the circulation roller 7222, and then the filter holes on the circulation mesh plate 7223 filter the water flow, so that the water flows into the drainage buffer pool 4 through the filter holes, and the carrying capacity of the carrying plate 7224 is used to completely pull the solids and debris onto the station base 1, and then the unloading structure 73 is used to clean up all the solids and debris and transport them to the station base 1, and the solids and debris are transported out manually on a regular basis.
[0044] The power assembly 723 includes a power motor 7231. The power motor 7231 is arranged on one side of the support frame 7211. The driving end of the power motor 7231 is connected to the upper circulation roller shaft 7222 through the reducer 7232. The reducer 7232 is rotated by the power motor 7231, so that the reducer 7232 drives the circulation roller shaft 7222 to rotate, thereby the circulation roller shaft 7222 drives the circulation mesh plate 7223 to reciprocate and rotate.
[0045] The material discharge structure 73 is installed on one side of the adjustable bracket 721, and the material discharge structure 73 cooperates with the circulating salvage device 722. The material discharge structure 73 includes a rotating roller brush 731, which is assembled on the station base 1 through a pair of fixing frames, and a material discharge hopper 732 is also assembled between the pair of fixing frames. The material discharge hopper 732 is located at the lower part of the rotating roller brush 731, and a cleaning motor is arranged at the shaft end of the rotating roller brush 731.
[0046] The unloading structure 73 uses a rotating roller brush 731 as the main cleaning device. The rotating roller brush 731 contacts the upper bottom surface of the circulating mesh belt, so that the solid impurities on the circulating mesh belt fall into the unloading hopper 732 under the brushing action of the rotating roller brush 731, and are discharged onto the ground of the station base 1 through the unloading hopper 732.
[0047] The lifting control structure 9 includes a control swivel seat 92, on which a control threaded rod 93 is mounted. The bottom end of the control threaded rod 93 is movably connected to a control gate 91, an adjusting dial 94 is disposed at the top end of the control threaded rod 93, and a guide groove 95 is disposed on the station base 1 corresponding to the control gate 91.
[0048] In the specific implementation process, the control threaded rod 93 is assembled by the control swivel seat 92, and the control threaded rod 93 is rotated by adjusting the turntable 94 to make the control threaded rod 93 engage with the control swivel seat 92, so that the control threaded rod 93 drives the control gate 91 to move during the lifting process, and the control gate 91 is guided and limited by the guide groove 95.
[0049] From the above, it can be generally known that the drainage station for preventing geological disasters in flood-prone areas after heavy rain adopts a drainage pump group 6 for drainage work, and a buffer tank is used on one side of the drainage pump group 6 in conjunction with a drainage filter 7 to remove solid impurities in the flood, thereby eliminating the impact of the solid impurities on the operation of the pump group, extending the use time of the pump group after a single start-up, reducing the number and difficulty of maintenance and cleaning of the pump group, and making the operation and maintenance of the pump group simpler and saving time and effort.
