TECHNICAL FIELD

[0001] The application relates to the technical field of drainage equipment, and discloses a drainage equipment for water conservancy and hydropower construction. BACKGROUND

[0002] In the process of water conservancy construction, drainage equipment is usually used to drain water bodies to facilitate subsequent construction. Currently, when water bodies are drained, a water pump is usually used to directly pump water.

[0003] Direct pumping of water by a water pump is a very scientific and convenient means and is applicable to various construction scenes. However, the problem of blockage of a water pumping pipe needs to be considered in the process of pumping water by a water pump.

[0004] Chinese Patent No. CN114772778B discloses a construction site drainage device, which comprises wheels, a first push rod, a reaction box, an observation transparent plate, a first fixed plate, a filter plate, a first fixed column, a second fixed column and a first water pipe. The reaction box is provided with wheels on the left and right sides of the lower part in a rotating manner. The first push rod is arranged on the left side of the lower part of the reaction box. The observation transparent plate is arranged on the front and back sides of the left side of the reaction box to observe the water accumulation in the reaction box. The first fixed plate is arranged on the top of the reaction box. The filter plate is arranged on the right side of the first fixed plate to filter the accumulated water. The first fixed column is arranged on the left side of the top of the first fixed plate. The second fixed column is arranged on the right side of the first fixed column. The first water pipe is arranged on the left side of the second fixed column. The device can clean the silt on the filter plate while pumping water, thereby preventing the filter plate from being blocked by silt. The main improvement of the above-mentioned drainage equipment lies in that the filter plate is arranged, and the water pumping pipe is not improved. The pumped water can pass through the water pumping pipe to the water pump and then leave the water pump through the drainage pipe. However, the water pump is not protected. This condition is only applicable to an environment in which the water quality is relatively pure and the foreign matters are few.

[0005] The above-mentioned scheme is not applicable to pumping water at a construction site. For most water conservancy construction sites, the water quality is low and the foreign matters are many. If the water pumping pipe is not limited, the foreign matters will enter the water pump through the water pumping pipe, which will cause damage to the water pump. Therefore, at present, a filter screen is installed at the inlet of the water pumping pipe to block the entry of large-particle foreign matters such as leaves and silt. Some professional devices also adopt a spring plug structure to prevent the reverse invasion of foreign matters by mechanical closure.

[0006] Although the installation of the filter screen at the inlet of the water pumping pipe can effectively block the entry of foreign matters into the water pump, the following problems still exist. 1. The inlet of the water pumping pipe is usually located at the bottom of a water pit. The filter screen can be placed in the water pit to completely pump water in a deep pit. However, the filter screen is inconvenient to clean. The water pump needs to be stopped, the filter screen needs to be lifted again, and then the foreign matters accumulated on the filter screen need to be cleaned, so as to ensure the pumping effect.

[0007] 2. The cleaning of the filter screen will inevitably cause the water pump to stop, which will lead to the decrease of the whole pumping efficiency.

[0027] The water pump body 2 is used for realizing water pumping and draining, and is an electrically controlled water pump body 2 provided with a control box 5, so that the suction force of the water pump body 2 is reasonably controlled by a controller in the control box 5. The water pump body 2 is fixed on the support 1 which is installed on the ground.

[0028] The water inlet pipe assembly 6 is detachably connected with the water inlet 3 for pumping water in a deep pit at a construction site. The water outlet pipe 7 is detachably connected with the water outlet 4 for draining water. The water inlet pipe assembly 6 includes a hose 601, a water suction disc 603, a hard pipe 604 connected with the water inlet 3, and a quick-release filter assembly 607 detachably connected with the hose 601. In order to quickly install and quickly release the water inlet pipe assembly 6 and the water outlet pipe 7, the water inlet 3 and the water outlet 4 are threaded openings, and the hard pipe 604 in the water inlet pipe assembly 6 and the water outlet pipe 7 are respectively screwed with the water inlet 3 and the water outlet 4. A waterproof tape is arranged at the threaded connection position to improve the sealing effect of the connection position.

[0031] Specifically, as shown in Figure 2 and Figure 3As shown, the quick-release filter assembly 607 is mounted at the bottom of the bearing frame 606, which is mainly used to bear the quick-release filter assembly 607. When the quick-release filter assembly 607 needs to be disassembled, the bearing frame needs to be disassembled first.

Both ends of the partition frame are threadedly connected with cover plates 6071 through the threaded sleeves 6072. The cover plates 6071 are integrally formed with the hose 601, and the inner wall of the threaded sleeve 6072 is provided with a locking thread 6079.

[0032] Specifically, the cover plate 6071 is threadedly connected with the threaded sleeve 6072. Since the cover plate 6071 is integrally formed with the hose 601, the quick-release filter assembly 607 is installed on the hose 601. The partition plate 6075 and the through hole 6074 form an independent passing area. The filter 6076 is installed between the bottom plate 6073. The side of the through hole 6074 close to the filter 6076 is provided with an elastic tube 6077. The end of the elastic tube 6077 is connected with a connector 6078. Both ends of the filter 6076 are threadedly connected with the connector 6078.

The groove is threadedly connected with a lug 36. A connecting rod 34 is arranged between the lug 36 and the boss 37. One end of the connecting rod 34 abuts against the lug 36. The other end of the connecting rod 34 penetrates out of the clamping block 32 and abuts against the boss 37.

[0036] Specifically: the quick-release filter screen realizes quick release, first the quick-release filter screen is released, then the protruding block 36 is disassembled, after the limiting of the protruding block 36 disappears, the connecting rod 34 and the clamping block 32 can be taken out, since the outer frame 35 is clamped on the clamping block 32, the outer frame 35 and the filter screen body 38 are disassembled.

[0037] In order to realize gradual filtering of impurities: the filter screen body 38 in the quick-release filter screen has different filter diameters, the filter diameter of the filter screen body 38 close to the water suction disc 603 is larger than that of the filter screen body 38 away from the water suction disc 603.

[0038] The specific implementation process is as follows: Firstly, the water inlet pipe assembly 6 and the water outlet pipe 7 are installed, the end of the water inlet pipe assembly 6 is manually put into the deep pit, the water pump body 2 is started, the water inlet pipe assembly 6 realizes water suction, and the water is discharged through the water outlet pipe 7; Secondly, all the electromagnetic switch valves are opened at this time, with the water discharge, impurities in the deep pit will enter the filter 6076, and over time, the filter screen body 38 in the filter 6076 will be blocked, so the filter screen body 38 needs to be cleaned; Thirdly, the filter 6076 is cleaned gradually, the filter 6076 to be cleaned is found, the corresponding electromagnetic switch valve of the filter 6076 is closed, then the quick-release filter assembly 607 is disassembled, the filter 6076 is separated from the hose 601, then the protruding block 36 is disassembled, after the limiting of the protruding block 36 disappears, the connecting rod 34 and the clamping block 32 can be taken out, since the outer frame 35 is clamped on the clamping block 32, the outer frame 35 and the filter screen body 38 are disassembled and cleaned, after cleaning, the corresponding electromagnetic switch valve is opened again, and the cleaning of all the filters 6076 is completed in this way, since the filters 6076 are cleaned one by one, the water pump body 2 does not need to be stopped, that is, the water suction continues, and the cleaning of the filters 6076 can be completed at the same time.

[0039] The device solves the problem that the traditional filter device arranged on the water suction pipe is not easy to replace.

[0040] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, although the present application has been disclosed as above with a preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not deviate from the technical solution of the present application, any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, all still belong to the scope of the technical solution of the present application.
