Description

Technical Field

[0001] The utility model relates to the technical field of water construction of water conservancy projects, in particular to a drainage device used in water conservancy project construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but with the development of human urbanization, the natural existence of rivers and lakes does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] At present, when carrying out water conservancy construction, it is often necessary to use drainage devices to drain the water in the foundation pit. When the existing drainage device is draining, the water inlet pipe often contacts the soil in the foundation pit, which makes it easy for the soil to enter and cause blockage. At the same time, the debris in the foundation pit will also enter with the water inlet pipe. The debris will accumulate. The filter will intercept the debris at the upper end and need to be cleaned in time to avoid affecting the subsequent drainage. Utility Model Content

[0004] The purpose of the utility model is to provide a drainage device for water conservancy project construction, which mainly solves the above-mentioned problems existing in the prior art by cooperating with each other through a support assembly arranged at the water inlet end of the water inlet pipe, a pressure rod and a pressure switch arranged on both sides of the filter screen, and timely reminding cleaning through an alarm.

[0025] Example 1

[0026] Embodiment 1 of the utility model is a drainage device for water conservancy project construction, including a base plate, a universal wheel 2 is arranged at the bottom of the base plate, a treatment box 5, a water pump 8 and a handrail 3 are arranged on the top of the base plate from left to right, and an inlet pipe 6 and an outlet pipe are arranged on both sides of the treatment box 5, respectively, the outlet pipe is connected to the water pump 8, and a support assembly 4 is arranged on the outside of the water inlet end of the water inlet pipe 6.

[0027] Reference Figure 1 In the drainage device of the present application, a support assembly 4 is provided on the periphery of the water inlet end of the water inlet pipe 6. The support assembly 4 is telescopic and movable to adjust the positional relationship between its bottom and the foundation pit, so that its bottom contacts the bottom of the foundation pit, so that the water inlet end is always away from the soil at the bottom of the foundation pit, preventing soil from entering the water inlet end and preventing drainage blockage. When the water level gradually decreases, the support assembly 4 will adjust the height of the water inlet end with the water level to avoid the water level being too low and the water inlet end being too high to allow water to enter.

[0028] The water entering the water inlet pipe 6 enters the treatment box 5 and the drain pipe 7 in turn for transfer and discharge. The interior of the treatment box 5 crushes and filters the incoming debris. When the debris accumulates to a certain extent, an alarm signal will be issued to remind workers to clean up the internal debris in time, which solves the need for workers to repeatedly check whether the debris on the filter screen 53 needs to be cleaned, thereby improving convenience.

[0029] In some preferred embodiments, the support assembly 4 includes a first annular plate 40 located at the outer periphery of the water inlet pipe 6, an annular cone block 45 is provided below the first annular plate 40, a first hydraulic rod 42 is provided between the first annular plate 40 and the annular cone block 45, and a telescopic end of the first hydraulic rod 42 is fixedly connected to the first annular plate 40. An insertion rod 46 is provided at the bottom of the annular cone block 45.

[0030] Specifically, refer to Figure 2The first annular block in the support assembly 4 provides conditions for the installation of the first hydraulic rod 42. The first hydraulic rod 42 drives the annular cone block 45 to move downward until the insertion rod 46 is inserted into the soil of the foundation pit to prevent the soil from contacting the water inlet pipe 6. When lowering the water inlet end, it is only necessary to start the retraction state of the first hydraulic rod 42. Since the telescopic end of the first hydraulic rod 42 is fixed below the foundation pit through the annular cone block 45 and the insertion rod 46, the base of the telescopic rod drives the water inlet pipe 6 to descend toward the telescopic end during retraction, so that the water inlet end is always below the water level to draw water to the water inlet pipe 6.

[0031] In some preferred embodiments, a first filter frame 11 is provided at the water inlet end of the water inlet pipe 6, a second hydraulic rod 43 is provided at the bottom of the first annular plate 40, a second annular plate 41 is provided at the telescopic end of the second hydraulic rod 43, and the second annular plate 41 is provided with a cleaning brush 44 that contacts the first filter frame 11.

[0032] A first filter frame 11 is provided at the bottom end of the water inlet pipe 6. The first filter frame 11 is a cylindrical structure with one end open. A second annular plate 41 is provided on the outer periphery of the first filter frame 11. A cleaning brush 44 is provided on the inner side of the second annular plate 41. The second hydraulic rod 43 drives the second annular plate 41 to move, so that the cleaning brush 44 can clean up the debris attached to the outer periphery of the first filter frame 11 in time to prevent the debris from clogging the filter holes of the first filter frame 11 and affecting the water inlet.

[0033] It should be noted that the first filter frame 11 mainly prevents large debris from entering the water inlet pipe 6 , but does not affect the water in the foundation pit from entering the water inlet pipe 6 .

[0034] In some preferred embodiments, a fixing plate 110 is provided in the first filter frame 11, and a rotating rod 111 passes through the fixing plate 110. The end of the rotating rod 111 located inside the first filter frame 11 is provided with a rotating blade 112, and the end of the rotating rod 111 located outside the first filter frame 11 is provided with a cleaning rod 113, and the cleaning rod 113 is in contact with the bottom surface of the first filter frame 11.

[0035] The debris at the bottom of the first filter frame 11 is mainly removed by contacting and rotating the cleaning rod 113. After the water in the foundation pit enters the water inlet pipe 6, a water flow direction is generated, and the rotating blades 112 in the first filter frame 11 rotate, so that the rotating rod 111 drives the cleaning rod to rotate to clean the debris at the bottom of the first filter frame 11. The function is performed through the water flow direction, which is beneficial to energy saving.

[0036] Example 2

[0037] This embodiment 2 is implemented on the basis of embodiment 1, the top of the processing box 5 is provided with a rotating shaft 51 connected to the first motor 50 and a stirring blade 52 located on the outer periphery of the rotating shaft 51, a filter 53 is provided below the rotating shaft 51, and protrusions 54 are provided at both ends of the filter 53, and the protrusions 54 are assembled in the assembly groove 57 provided in the processing box 5. A support plate 55 is provided at the bottom of the assembly groove 57, a pressure switch 550 is provided above the support plate 55, a pressure rod 540 is provided below the protrusion 54, a spring 56 is provided between the pressure rod 540 and the pressure switch 550, and the pressure switch 550 is electrically connected to the alarm 10 through a wire.

[0038] In this application, reference is made to Figure 3 The stirring blade 52 disposed inside the processing box 5 crushes the smaller debris entering the processing box 5, and at the same time makes the debris accumulate on the filter screen 53. When the accumulated weight of the debris is large, the filter screen 53 moves through the pressure rod 540 under the protrusion 54 under the action of the spring 56 until the pressure rod 540 contacts the pressure switch 550, and the alarm 10 electrically connected to the pressure switch 550 will sound an alarm, reminding the worker to promptly remove the debris accumulated on the filter screen 53 inside the processing box 5. It is avoided that the worker checks whether the debris on the filter screen 53 needs to be cleaned every time, thereby improving work efficiency.

[0039] In some preferred embodiments, a threaded rod 13 connected to the second motor 15 is arranged above the filter screen 53, a moving rod 14 is arranged on the outer periphery of the threaded rod 13, a scraper 140 in contact with the surface of the filter screen 53 is arranged at the bottom end of the moving rod 14, and the processing box 5 is connected to the waste collection box 9 through an inclined pipeline.

[0040] When there are a lot of debris on the filter screen 53, the second motor 15 is driven to work, and the moving rod 14 on the outer periphery of the threaded rod 13 will move, thereby driving the scraper 140 below the moving rod 14 to remove the debris on the surface of the filter screen 53 to the inclined pipeline so that the debris can be stored in the waste collection box 9. The scraper 140 is always in contact with the surface of the filter screen 53 to play a role in removing debris.

[0041] In some preferred embodiments, a second filter frame 12 is provided at the end of the water outlet pipe located inside the treatment box 5 .

[0042] The structure of the second filter frame 12 is the same as that of the first filter frame 11 , and the second filter frame 12 prevents the fine debris filtered by the filter screen 53 from affecting the drain pipe 7 , thereby preventing the drain pipe 7 from being blocked. The filter holes of the second filter frame 12 are smaller than those of the first filter frame 11 .

[0043] When the utility model is used, firstly, according to the depth of the foundation pit, the first hydraulic rod 42 is driven to work, so that its telescopic end and the annular cone block 45 are lowered to the bottom of the foundation pit, and at the same time, the insertion rod 46 is extended below the foundation pit. The water inlet end of the water inlet pipe 6 is always located below the water surface under the action of the first hydraulic rod 42, and the end of the water inlet pipe 6 is provided with a first filter frame 11 to remove larger pieces of debris. The second hydraulic rod 43 drives the cleaning brush 44 in the second annular block to remove debris from the periphery of the first filter frame 11, and the water flow causes the rotating blade 112 to rotate so that the rotating rod 111 drives the cleaning rod 113 to remove the debris at the bottom of the first filter frame 11; The water inside the sorting box 5 is broken into small pieces of debris by the stirring blades 52, and the debris will accumulate on the filter screen 53. When there are too many accumulated debris, the pressure rod 540 under the protrusion 54 moves downward to contact the pressure switch 550 and activate the alarm, thereby turning on the second motor 15 to enable the scraper 140 under the moving rod 14 to clean the debris into the waste collection box 9, avoiding workers to repeatedly check whether the debris above the filter screen 53 has been cleaned; if there are small particles of debris in the water passing through the filter screen 53, a second filter frame 12 is provided at the end of the drain pipe 7 to filter and discharge the water, avoiding blockage of the drain pipe 7.

[0044] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
