Description

Technical Field

[0001] The utility model relates to a water source well, in particular to an assembled water source well used for taking water from surface water sources. Background Art

[0002] Surface water refers to the water bodies that exist on the Earth's surface, including rivers, lakes, glaciers, reservoirs, and groundwater. These bodies of water form the hydrosphere, one of Earth's most important water resources and a major component of every country's water resources. Especially in regions with well-developed water systems, most of the water used for human activities and industrial production comes from surface water.

[0003] The water source wells used in the process of surface water extraction are mostly brick-concrete structures. The surface water is initially filtered through filter holes evenly distributed on the water source wells and then stored in the water source wells. The primary filtered water in the water source wells is then pumped to the purification pool through a water pump. After sedimentation, disinfection and other processes, it is pumped to various living points and industrial and mining enterprises to become daily living water and industrial production water for humans. This type of water source well has the characteristics of safe and reliable operation, but it also has the disadvantages of long construction period, great construction difficulty and high cost, especially after the filter holes are blocked, it is inconvenient to maintain. Summary of the Invention

[0004] The purpose of the utility model is to provide an assembled water source well for drawing water from surface water sources, which has a simple structure, is safe and reliable in operation, and is easy to maintain.

[0005] The technical solution of the utility model is as follows:

[0006] A assembled water source well for drawing water from a surface water source, which consists of a water intake well equipped with a water pump and a plurality of filter wells arranged around the water intake well and connected to the water intake well. The invention is characterized in that the water intake well and the filter well respectively include a central tube, an outer tube and a filter layer, the central tube is provided with a plurality of stacked outer tubes, and a stacked filter layer is provided between the outer tube and the central tube.

[0007] The outer cylinder and filter layer at the bottom of the water intake well and the filter well are respectively provided with communication holes. The central cylinder of the water intake well is connected with multiple communication pipes, which pass through the communication holes and are connected with the central cylinder of the filter well.

[0008] The filter layer comprises a filter frame, a filter filler and a lifting hook. The filter frame is filled with the filter filler, and a lifting hook is movably installed on the top of the filter frame.

[0009] The central tube is provided with a positioning seat, the filter frame is provided with a positioning groove, and the positioning groove is connected to the positioning seat in a sleeve.

[0010] The filter frame, outer cylinder and central cylinder respectively include a frame and a filter plate fixed on the frame, and the filter plates are uniformly distributed with filter holes.

[0011] The beneficial effects of the present invention compared with the prior art are:

[0012] The outer cylinder and filter layer of the water source well used for surface water extraction are respectively stacked structures. The filter layer and outer cylinder can be removed in sequence. At the same time, the filter layer can be easily pulled up by the lifting hook provided on the filter layer, which greatly facilitates connection and disassembly, thereby facilitating maintenance when the filtering capacity decreases after clogging. By providing multiple filter wells, the filtration speed can be effectively increased, so that water can be quickly and massively returned to the central cylinder of the water well, which can effectively increase the water extraction speed. This solves the problems of existing water source wells that are difficult to install, have a long construction period, and are difficult to maintain after clogging.

[0020] The assembled water source well for drawing water from a surface water source is composed of a water intake well 1 and a filter well 2. A water pump is provided in the water intake well 1 to extract water from the water intake well 1 after initial filtration for water intake. The water intake well 1 is surrounded by multiple filter wells 2, which are connected to the water intake well 1. The function of the filter well 2 is to filter water through the filter well 2 in cooperation with the water intake well 1, and to collect the filtered water into the water intake well 1. The filtration surface is expanded by multiple filter wells 2 and the water intake well 1, thereby enhancing the filtration capacity. Since the filter well 2 is connected to the water intake well 1, the water filtered by the filter well 2 can flow into the water intake well 2, so that the water intake well 1 can quickly and in large quantities return water, thereby effectively enhancing the water intake speed.

[0021] The water intake well 1 and filtration well 2, respectively, consist of a central tube 201, an outer tube 202, and a filter layer 203. Multiple outer tubes 202 are stacked on top of the central tube 201, with the bottom of the central tube 201 fixedly connected to the outer tubes 202. A stack of filter layers 203 is located between the outer tubes 202 and the central tube 201. The outer tubes 202 perform a preliminary filtration of large impurities in the water (such as branches and water plants), while also protecting them from the impact of water flow and impurities. The filter layer 203 further filters small impurities in the water (such as silt and rotting leaves), further purifying the water and preventing impurities from entering the central tube 201 and the water pump, thus reducing clogging during the water intake process. The central tube 201 performs a final filtration of the water, simultaneously collecting the filtered water for easier pumping. Since the outer cylinder 202 and the filter layer 203 are stacked separately, the outer cylinder 202 and the filter layer 203 can be disassembled layer by layer, thereby effectively reducing the weight of the outer cylinder 202 and the filter layer 203 disassembled at a time. As a result, the outer cylinder 202 and the filter layer 203 can be disassembled and assembled much more conveniently. After the outer cylinder 202 and the filter layer 203 are blocked, the outer cylinder 202 and the filter layer 203 can be conveniently disassembled and cleaned and maintained.

[0022] The outer cylinder 202 and the filter layer 203 at the bottom of the water intake well 1 and the filter well 2 are respectively provided with a connecting hole 204. The central cylinder 201 of the water intake well 1 is connected to a plurality of connecting pipes 205, which pass through the connecting holes 204 and communicate with the central cylinder 201 of the filter well 2. The function of the connecting pipes 205 is to connect the central cylinder 201 of the filter well 2 with the central cylinder 201 of the water intake well 1 through the connecting pipes 205, thereby allowing the filtered water collected in the central cylinder 201 of the filter well 2 to flow into the central cylinder 201 of the water intake well 1, so that the water in the central cylinder 201 of the filter well 2 can be quickly replenished to the central cylinder 201 of the water intake well 1, ensuring that the water pump in the central cylinder 201 of the water intake well 1 can quickly extract a large amount of filtered water, effectively improving the water intake speed.

[0023] The filter layer comprises a filter frame 2031, a filter filler, and a lifting hook 2032. The filter frame 2031 is filled with the filter filler, which consists of 2-5 cm pebbles, quartz sand, or other large, water-insoluble particles. Because the filter filler is particulate, it creates abundant pores between the fillers. These pores trap bulky impurities while allowing loose water to pass through the filler, thereby filtering and purifying the water. A lifting hook 2032 is movably mounted on the top of the filter frame 2031. The lifting hook 2032 can be folded into the filter filler, freeing it from occupying the space above the filter layer 203. This allows two adjacent filter layers 203 to be stacked seamlessly, effectively ensuring filtration efficiency. The lifting hook 2032 can also be rotated to a vertically upward position, allowing the filter layer 203 to be easily lifted and removed.

[0024] A positioning seat 2011 is provided on the center tube 201, and a positioning slot 2033 is provided on the filter frame 2031. The positioning slot 2033 is integrally connected to the positioning seat 2011. The positioning seat 2011 cooperates with the positioning slot 2033 to limit the position of the filter frame 2031, so that the filter frame 2031 can only move up and down along the positioning seat 2011. This prevents the filter frame 2031 from tilting during installation, thereby preventing the filter filler in the filter frame 2031 from spilling.

[0025] The filter frame 2031 , the outer tube 202 and the central tube 201 respectively include a frame and a filter plate fixed on the frame, and the filter holes 2012 are evenly distributed on the filter plate.

[0026] An end cover 206 is provided on the top of the central tube 201 to seal the top of the central tube 201 , thereby preventing people and animals from falling into the central tube 201 and causing danger.

[0027] When installing the assembled water source well for drawing water from surface water sources, a central foundation pit with a depth of 50 and multiple peripheral foundation pits surrounding the central foundation pit are dug at the water source. After the foundation pit excavation is completed, the central tube 201 with the outer tube 202 fixedly installed on the bottom is lowered into each foundation pit. During the process of lowering the central tube 201, the central tubes 201 in the peripheral foundation pits are connected to the central tube 201 in the central foundation pit through the connecting pipe 205. After the lowering and installation of the central tube 201 is completed, the foundation pit is backfilled or the central tube 201 and the outer tube 202 are fixed in the foundation pit by cement curing. After the installation of the central tube 201 is completed, the filter layer 203 and the outer tube 202 are installed on the central tube 201 layer by layer until the outer tube 202 and the filter layer 203 are flush with the top of the central tube 201. After the installation of the filter layer 203 and the outer tube 202 is completed, a water pump is installed in the central tube 201 of the water intake well 1 in the central foundation pit. After the water pump is installed, the water source well is completed.

[0028] When the water source well is drawn from, the outer cylinder 202, filter layer 203 and central cylinder 201 of the filter well 2 and the water intake well 1 filter the water at one time and collect the water into the central cylinder 201. The water in the central cylinder 201 of the filter well 2 is collected into the central cylinder 201 of the water intake well 1 through the connecting pipe 205. The water in the central cylinder 201 of the water intake well 2 is pumped outward by the water pump in the central cylinder 201 of the water intake well 2 to draw water.

[0029] The outer cylinder 202 and filter layer 203 of the water source well for drawing water from a surface water source are respectively a stacked structure. The filter layer 203 and the outer cylinder 202 can be removed in sequence. At the same time, the filter layer 203 can be easily pulled up by the lifting hook 2032 provided on the filter layer 203, which greatly facilitates connection and disassembly, thereby facilitating maintenance when the filtering capacity decreases after clogging. By providing multiple filter wells 2, the filtering speed can be effectively increased, so that water can be quickly and in large quantities returned to the central cylinder 201 of the water well 1, which can effectively increase the water intake speed. This solves the problems of existing water source wells being difficult to install, having a long construction period, and being difficult to maintain after clogging.
