Description

Technical Field

[0001] This invention mainly relates to the field of hydrogeological sampling technology, specifically a groundwater collection and filtration device. Background Technology

[0002] Groundwater is an important component of water resources and has a close relationship with human society. The storage of groundwater is like forming a huge reservoir underground. With its stable water supply and good water quality, it has become an important water source for agricultural irrigation, industrial and mining enterprises, and urban domestic water use.

[0003] To better utilize groundwater, hydrogeological surveys often involve groundwater sampling and testing. Many groundwater sources contain impurities, and during sampling, soil, stones, and other particles are frequently encountered, which can clog filters, slowing down the groundwater intake or even severely clogging them, making it impossible to continue the sampling process. In such cases, it is usually necessary to disassemble the sampling equipment for cleaning or replace the filter cartridge, which can seriously affect work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a groundwater collection and filtration device that, through a novel structural design, achieves multi-stage filtration of groundwater and effectively self-cleans to prevent filter blockage from affecting collection efficiency.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A groundwater collection and filtration device includes a collection cylinder, a filter cylinder, and a connecting sleeve. The collection cylinder and the filter cylinder are fixedly connected together by the connecting sleeve. A connecting channel is provided between the collection cylinder and the filter cylinder. A secondary filter element is installed in the connecting channel. An adjusting cover is installed on the filter cylinder. A drive motor is fixedly installed in the middle of the adjusting cover. A drive shaft is installed on the output shaft of the drive motor. A filter brush is movably installed at the bottom end of the drive shaft. A water inlet is provided at the bottom of the filter cylinder. The filter brush is located outside the water inlet. A primary filter element is fixedly installed on the drive shaft inside the water inlet. A spiral blade is provided on the drive shaft inside the filter cylinder at the height of the connecting sleeve. Several rotating paddles are fixedly installed on the drive shaft inside the filter cylinder. Several external openings are opened on the adjusting cover. An adjusting plate is rotatably connected to the inside of the adjusting cover. An internal opening is opened on the adjusting plate. The size and shape of the internal opening correspond to the external openings.

[0007] A sealing cover is movably installed on the collection tube. A stepped block is provided on the sealing cover, and a one-way interface is provided in the middle of the stepped block.

[0008] A battery compartment is fixedly installed on the connecting sleeve, and a battery compartment bracket is fixedly connected between the collection tube and the filter tube.

[0009] A lifting ring is fixedly connected to the upper part of the connecting channel.

[0010] A protective bracket is installed below the bottom filter cylinder of the connecting sleeve.

[0011] A rotating plate adjustment motor is fixedly installed on the adjustment cover, and the rotating plate adjustment motor drives the adjustment plate to rotate.

[0012] The filter brush is provided with several stiff bristles.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention enables primary filtration of water via a filter brush, effectively preventing large particles from clogging the inlet and affecting water intake. It also has a certain self-cleaning function. The primary filter effectively filters impurities in the incoming water, and the funnel-shaped filter design allows for self-cleaning during slow or non-flowing water. The secondary filter thoroughly filters impurities in the water, and the water inlet structure in the filter cartridge allows for rinsing and cleaning of the secondary filter, effectively preventing the problem of slow water intake and reduced sampling efficiency caused by filter clogging. This allows the device to be used for sampling even in relatively turbid water. Attached Figure Description

[0021] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Combined with appendix Figure 1-5 A groundwater collection and filtration device includes a collection cylinder 1, a filter cylinder 2, and a connecting sleeve 3. The collection cylinder 1 and the filter cylinder 2 are fixedly connected together by the connecting sleeve 3. A connecting channel 4 is provided between the collection cylinder 1 and the filter cylinder 2. A secondary filter element 5 is installed in the connecting channel 4. An adjusting cover 6 is installed on the filter cylinder 2. A drive motor 7 is fixedly installed in the middle of the adjusting cover 6. A drive shaft 8 is installed on the output shaft of the drive motor 7. A filter brush 9 is movably installed at the bottom end of the drive shaft 8. A water inlet 1 is provided at the bottom of the filter cylinder 2. 0. The filter brush 9 is located outside the water inlet 10. A primary filter element 16 is fixedly installed on the drive shaft 8 inside the water inlet 10. A spiral blade 11 is installed on the drive shaft 8 inside the filter cylinder 2 at the height of the connecting sleeve 3. Several rotating paddles 12 are fixedly installed on the drive shaft 8 inside the filter cylinder 2. Several external openings 13 are opened on the adjusting cover 6. An adjusting plate 14 is rotatably connected to the inside of the adjusting cover 6. An internal opening 15 is opened on the adjusting plate 14. The size and shape of the internal opening 15 correspond to the external openings 13.

[0023] A sealing cover 21 is movably installed on the collection tube 1. A stepped block 22 is provided on the sealing cover 21, and a one-way interface 20 is provided in the middle of the stepped block 22. The stepped block 22 is used to rotate to install or open the sealing cover 21. The one-way interface 20 penetrates the sealing cover 21, and only water is allowed to flow in one direction within the one-way interface 20, that is, water flows out of the collection tube 1 or excess air is discharged when water enters the collection tube 1.

[0024] A battery compartment 31 is fixedly installed on the connecting sleeve 3, and a battery compartment bracket 32 ​​is fixedly connected between the collection tube 1 and the filter tube 2; there are two battery compartments 31, and the top of the battery compartment 31 has a detachable sealing cap to achieve underwater sealing. A lithium battery is installed in the battery compartment 31; the drive motor 7 is a waterproof motor.

[0025] A lifting ring 40 is fixedly connected to the upper part of the connecting channel 4; the lifting ring 40 is used to lower the device into the water using a rope and a hook.

[0026] A protective bracket 50 is provided below the bottom filter cylinder 2 of the connecting sleeve 3. The protective bracket 50 is used to protect the filter brush 9 from contact with the bottom of the water or hard objects in the water, which may cause damage.

[0027] The adjusting cover 6 is fixedly installed with a rotating plate adjusting motor 60, which drives the adjusting plate 14 to rotate.

[0028] The filter brush 9 is provided with a plurality of hard bristles 90; the plurality of hard bristles 90 can perform preliminary filtration of the water entering the filter cylinder 2, and can prevent large particles from entering the filter cylinder 2. At the same time, the rotating hard bristles 90 can cause the particles stuck between the hard bristles 90 under the action of the incoming water flow to rotate with the filter brush 9. When the water in the filter cylinder 2 reaches saturation and the water pressure is maintained, the water flow rate in the inlet 10 is very low. At this time, under the action of rotational centrifugal force, the particles stuck between the hard bristles 90 can gradually be removed from the filter brush 9, thereby achieving preliminary filtration and self-cleaning of the water flow to a certain extent.

[0029] The connecting sleeve 3 houses a control circuit board. The device also includes a remote control; the operator sends a control signal to the control circuit board via the remote control, which then controls the corresponding drive components to operate. The device has a metal casing and is relatively heavy, allowing it to automatically sink into the water even when no water is being collected in the collection tube 1. The device also includes a monitoring device to monitor the water volume, pressure, and temperature in the collection tube 1, as well as the water pressure in the filter tube 2. The one-way interface 20 has a one-way control valve; as water continuously enters the collection tube 1, the gas in the collection tube 1 can... The water is discharged through the one-way interface 20 to ensure smooth water intake. The outer end of the primary filter element 16 is rotatably connected to the water inlet 10. The bottom of the primary filter element 16 is funnel-shaped, which allows the centrifugal force generated by rotation to remove the filter material attached to the outside of the primary filter element 16 when a certain water pressure is maintained in the filter cylinder 2 and water is not introduced or is introduced slowly, thus achieving a self-cleaning effect. The primary filter element 16 and the secondary filter element 5 can be replaced with filter elements of different filtration capacities according to usage requirements. In use, the filtration capacity of the secondary filter element 5 is greater than that of the primary filter element 16 to achieve a multi-stage filtration effect.

[0030] The adjusting cover 6 is threaded onto the filter cylinder 2. The rotation direction of the drive motor 7 is opposite to the threaded installation direction of the adjusting cover 6. This setting can prevent the reaction force of the drive motor 7 from loosening the adjusting cover 6 from the filter cylinder 2.

[0031] The spiral blade 11 is used to drive and pressurize the water inlet in the filter cylinder 2. Together with the adjusting cover 6, it realizes the water pressure regulation in the filter cylinder 2. That is, when the inner opening 15 and the outer opening 13 of the adjusting cover 6 are misaligned, the spiral blade 11 drives the water into the filter cylinder 2, which can increase the water pressure in the filter cylinder 2. The higher the rotation speed of the spiral blade 11, the higher the water pressure in the filter cylinder 2, thus enabling pressurization and regulation of the water pressure.

[0032] In use, this device is placed into the water to be sampled using a rope and hook. The device is then activated via remote control. The rotating plate adjustment motor 60 first drives the adjusting plate 14 to rotate, aligning the inner opening 15 with the outer opening 13 on the adjusting cover 6. The drive motor 7 then rotates the drive shaft 8, causing the spiral blades 11 to rapidly drive water into the filter cylinder 2. After a set time, the filter cylinder 2 is filled with water filtered by the filter brush 9 and the primary filter element 16. The rotating plate adjustment motor 60 then drives the plate to rotate, causing the inner opening 15 and outer opening 13 to be misaligned. At this point, water cannot flow out of the filter cylinder 2 through the adjusting cover 6. The drive motor 7 continues to rotate the drive shaft 8. Due to the continuous driving of the spiral blades, the water pressure in the filter cylinder 2 increases, and under pressure, the water continuously permeates through the secondary filter element 5 into the collection cylinder 1, thus collecting and filtering groundwater. Operation: When the water volume in the collection tube 1 reaches the set collection volume, the device is removed from the water. The drive motor 7 continues to work to maintain a certain water pressure in the filter tube 2, preventing water in the collection tube 1 from back-osmosis into the filter tube 2. The collected water is taken out and stored by connecting the one-way interface 20 of the device to the water sample storage container through the pipeline. When the secondary filter element 5 is clogged by filter material, the device can be remotely activated to start the self-cleaning mode. In this mode, the rotating plate adjustment motor 60 drives the adjustment plate 14 to rotate, so that the inner opening 15 is aligned with the outer opening 13 on the adjustment cover 6. The drive motor 7 increases the rotation speed. At this time, the water flows quickly into the filter tube 2 from the inlet 10 and flows quickly out of the filter tube 2 from the inner opening 15 and the outer opening 13. The rotating paddle 12 inside the filter tube 2 accelerates the water flow in the filter tube 2, thereby effectively flushing the surface of the secondary filter element 5 and achieving the self-cleaning effect.
