Description

Technical Field

[0001] The utility model relates to the technical field of groundwater extraction, in particular to a groundwater extraction device. Background Art

[0002] Groundwater refers to the water stored in the rock voids below the ground surface. Narrowly speaking, it refers to the water in the saturated aquifer below the groundwater level. Groundwater is an important part of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial and mining, and cities. However, under certain conditions, the change of groundwater will also cause adverse natural phenomena such as waterlogging, salinization, landslides, and land subsidence.

[0003] After the existing groundwater extraction device is used up, the water suction pipe is directly wound up, and the sludge on the outer wall of the water suction pipe is also wound in. When carrying and storing after winding up, the weight will be increased, consuming a lot of physical strength of the staff. Moreover, after the sludge is dehydrated and dried, it will become mud blocks, which will fall to the ground or transportation tools during the moving process when used again, polluting the ground and transportation tools. Summary of the Utility Model

[0004] The utility model aims at the above problems in the prior art and provides a groundwater extraction device, which is realized through the following technical solutions:

[0005] A groundwater extraction device includes a bottom plate. A water pump, a mud removing structure, and a reel are sequentially installed on the top of the bottom plate. A square opening is formed at the bottom of the mud removing structure on the bottom plate. The water outlet end of the water pump is flange-connected to a water outlet pipe. The water inlet end of the water pump is flange-connected to an elbow pipe. One end of the elbow pipe far away from the water pump is flange-connected to a water inlet hose. The water inlet hose sequentially passes through the mud removing structure and the square opening and extends underground. The mud removing structure includes legs, two support plates, and two mud removing plates. The two support plates are both fixed to both ends of the square opening through the legs. The two mud removing plates are arranged on both sides of the square opening. The two support plates and the two mud removing plates form a square to surround the water inlet hose. Slide grooves are formed on the side walls of the two support plates. Two sliders are slidably installed in each of the two slide grooves. The mud removing plates are fixed between the sliders at both ends. Threaded holes are formed in the parts of the sliders extending outside the slide grooves. The sliders in the same slide groove can be fixed by bolts.

[0006] The utility model is further arranged as follows: The cross-sections of the two mud removing plates on both sides are two right-angled inverted triangles, and the right-angled sides of the mud removing plates are close to the water inlet hose.

[0007] The utility model is further arranged as follows: Limiting blocks are installed on the sides of the two sliders close to each other. Threaded holes are also formed in the limiting blocks. Bolts pass through the sliders and the limiting blocks for fixation.

[0008] The present utility model is further configured as follows: The reel includes a support base, a turntable, and a handwheel. The support base is fixed to the top of the bottom plate. The turntable is disposed on one side of the support base. A rotating shaft is fixedly installed at the middle position of the turntable. The rotating shaft penetrates through the support base and is rotatably connected to the support base. The handwheel is installed on the side of the rotating shaft away from the turntable. Two support frames are installed on the side of the turntable where the rotating shaft is not installed.

[0009] The present utility model is further configured as follows: A handle for pushing and pulling is installed on one side of the bottom plate close to the water pump. Universal wheels with self-locking functions are installed at the four corners of the bottom of the bottom plate.

[0010] In summary, the beneficial technical effects of the present utility model are as follows:

[0011] During the winding process, the sludge on the outer wall of the water inlet hose is cleaned by the de-sludging structure, preventing the sludge from being wound in, reducing the weight of the water inlet hose, and the cleaned sludge directly falls to the ground, without soiling the surrounding ground and transportation tools, facilitating handling during re-use, and avoiding the falling of dehydrated and dried soil blocks.

[0018] Embodiment

[0019] As Figures 1-4As shown in the figure, a groundwater extraction device disclosed by the present utility model includes a bottom plate 1. On the top of the bottom plate 1, a water pump 2, a de-silting structure and a winder 3 are sequentially installed. A square opening 101 is formed at the bottom of the de-silting structure of the bottom plate 1. The water outlet end of the water pump 2 is flange-connected to a water outlet pipe. The water inlet end of the water pump 2 is flange-connected to an elbow pipe 4. One end of the elbow pipe 4 away from the water pump 2 is flange-connected to a water inlet hose 5. The water inlet hose 5 passes through the de-silting structure and the square opening 101 in sequence and extends underground. A filter screen is installed at one end of the water inlet hose 5 extending underground. The de-silting structure includes legs 6, two support plates 7 and two de-silting plates 8. The two support plates 7 are both fixed to both ends of the square opening 101 through the legs 6. The two de-silting plates 8 are arranged on both sides of the square opening 101. The two support plates 7 and the two de-silting plates 8 form a square to surround the water inlet hose 5. Slide grooves 701 are formed on the side walls of the two support plates 7. Two sliders 702 are respectively and slidably installed in the two slide grooves 701. The de-silting plate 8 is fixed between two sliders 702 on different support plates 7 on the same side. Threaded holes are formed in the parts of the sliders 702 extending outside the slide grooves 701. The two sliders 702 in the same slide groove 701 can be fixed by bolts.

[0020] The cross-sections of the two de-silting plates 8 on both sides are two right-angled inverted triangles, and the right-angled sides of the de-silting plates 8 are close to the water inlet hose 5.

[0021] Limit blocks 703 are installed on the sides of the two sliders 702 close to each other. When the sliders 702 are fixed by bolts, a gap is ensured to be left in the middle to prevent the water inlet hose 5 from being unable to pass due to clamping. Threaded holes are also formed in the limit blocks 703, and the bolts pass through the sliders 702 and the limit blocks 703 for fixation.

[0022] The winder 3 includes a support base 301, a turntable 302 and a handwheel 303. The support base 301 is fixed to the top of the bottom plate 1. The turntable 302 is arranged on one side of the support base 301. A rotating shaft 304 is fixedly installed in the middle of the turntable 302. The rotating shaft 304 passes through the support base 301 and is rotatably connected to the support base 301. The handwheel 303 is installed on the side of the rotating shaft 304 away from the turntable 302. Two support frames 305 are installed on the side of the turntable 302 without the rotating shaft 304. The flange of the water inlet hose 5 is clamped between the two support frames 305 for fixation, and the handwheel 303 is rotated to wind up the water inlet hose 5.

[0023] A handle 9 for pushing and pulling is installed on one side of the bottom plate 1 close to the water pump 2. Universal wheels 10 with self-locking functions are installed at the four corners of the bottom of the bottom plate 1.

[0024] Specific implementation manner of this example: Push this device to the water intake location, align the square opening 101 with the material discharge wellhead, rotate the handwheel 303 to lower the water inlet hose 5 into the well. After it is completely lowered, remove the other end of the water inlet hose 5 from between the support frames 305 and connect it to the elbow 4 by flange connection. Connect the water outlet end of the water pump 2 to the water outlet pipe, start the water pump 2 to draw water. After the water intake is completed, remove the water inlet hose 5, and snap one end of the connecting flange into the space between the two support frames 305. Slide the mud removal plates 8 on both sides to squeeze the water inlet hose 5 so that the limit blocks 703 on both sides come into contact and fix them with bolts. Reverse the handwheel 303 to wind up the water inlet hose 5. The sludge on the outer wall of the water inlet hose 5 is scraped off into the well under the action of the mud removal plates 8. After the cleaning of the water inlet hose 5 is completed, remove the bolts and slide the mud removal plates 8 on both sides to wind up the end of the water inlet hose 5 that has not been wound up finally. After the winding up is completed, remove the water inlet hose 5 as needed and carry out transportation or storage.
