Description

Technical Field

[0001] This utility model relates to the field of multi-layer filtration water quality testing technology, and in particular to a water quality testing device with a multi-layer filtration structure. Background Technology

[0002] Multi-stage filtration water quality testing is a process that combines physical filtration with real-time water quality monitoring. It is primarily used to purify water and monitor water quality parameters in real time to ensure that the effluent meets safety standards. Its core design involves removing impurities and contaminants through a multi-stage filtration system, while simultaneously using sensors and intelligent analysis modules to dynamically monitor water quality.

[0003] In multi-layer filtration water quality testing, existing technologies often utilize multiple filtration systems composed of various filter materials to purify water sources. Once the water source meets the standards, it needs to be transported to a designated location. This requires frequent connection to the pipelines of various equipment. However, existing water quality testing devices cannot quickly and accurately connect their outlet pipes to other pipelines when frequently connected to various equipment, and water leaks may occur. This leads to low work efficiency and waste of water resources.

[0004] Existing technologies, such as the utility model patent with publication number CN213834766U, disclose a water quality testing device with a filtering effect. This utility model discloses a water quality testing device with a filtering effect, including a housing. The lower end of the housing is fixedly connected to equidistantly distributed legs. A water inlet pipe is fixedly connected to the upper left side of the housing. A first water quality detector is fixedly connected to the upper end of the housing, and a first probe is fixedly connected to the lower end of the first water quality detector. A particulate filter layer, a primary filter layer, and a secondary filter layer are movably connected sequentially from left to right inside the housing. Equidistantly distributed slots are provided inside the housing and at the upper end. This water quality testing device with a filtering effect forms a water filtration system through the primary filter layer, the secondary filter layer, and the particulate filter layer. The particulate filter layer has a perforated mesh structure, which can block and filter large particulate impurities. The primary filter layer is made of PP cotton material, which can adsorb small particulate impurities. The secondary filter layer is made of activated carbon material, which can effectively remove odors, chlorine, cyanide, and various heavy metal ions and other harmful substances.

[0005] The above findings reveal the following shortcomings: In multi-layer filtration water quality testing, existing technologies often utilize multiple filtration systems composed of various filter materials to purify water sources. Once the water source meets the standards, it needs to be transported to a designated location. This requires frequent connection to the pipelines of various devices. However, existing water quality testing devices cannot quickly and accurately connect their outlet pipes to other pipelines when frequently connected to various devices, which may also lead to water leaks. This results in low work efficiency and water waste. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing water quality testing devices, which are unable to quickly and accurately connect their outlet pipes to other pipes when frequently connected to various equipment, and may also cause water leakage. This results in low work efficiency and waste of water resources. Therefore, this invention proposes a water quality testing device with a multi-layer filtration structure.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a water quality testing device with a multi-layer filtration structure, comprising a testing chamber, an inlet pipe, an outlet pipe, a connecting pipe, a display screen for displaying water quality, and a placement device for holding the water filtration material. One side of the testing chamber is provided with a docking device for connecting the outlet pipe and the connecting pipe. The docking device includes a round rod, which is fixedly connected to one side of the testing chamber. A first circular ring rod is fixedly connected to the arc surface of the round rod, and a second circular ring rod is slidably connected to the arc surface of the round rod. A retaining ring is fixedly connected to the lower ends of both the first and second circular ring rods. The circular arc surface of the retaining ring is fixedly connected to two mounting blocks. One side of each of the two mounting blocks is threaded with a first screw, which is threaded to the retaining ring. The circular arc surface of each of the two retaining rings is fixedly connected to a mounting plate. One side of one mounting plate is rotatably connected to a second screw, and the other mounting plate is threaded to the second screw. The side of the round rod away from the detection box is fixedly connected to an L-shaped plate. The long arm end of the L-shaped plate is fixedly connected to the detection box. The connecting pipe is slidably connected to the L-shaped plate. The short arm end of the second screw is threaded to the L-shaped plate. The two retaining rings are respectively fitted onto the circular arc surfaces of the connecting pipe and the outlet pipe.

[0008] The effect achieved by the above components is as follows: after the water passes through layers of filtration and meets the standards, it will be transported to a designated location for storage through the outlet pipe. At this time, rotating the second screw drives the second ring rod to move the connecting pipe along the ring rod towards the outlet pipe until it is fully connected to the outlet pipe, thus achieving the effect of quickly connecting to the water supply pipeline.

[0009] Preferably, one end of the first screw is fixedly connected to an anti-slip pad, which can completely fit with the water outlet pipe or connecting pipe.

[0010] The effect achieved by the above components is that when the connecting pipe or water outlet pipe is placed in the retaining ring, rotating the two first screws will make the anti-slip pad fit with it, which can prevent the pipe from slipping out of the retaining ring.

[0011] Preferably, a connecting ring is fixedly connected to the end of the water outlet pipe away from the detection box, and a sealing gasket is fixedly connected to the end of the connecting ring away from the water outlet pipe.

[0012] The effect achieved by the above components is that after the connecting pipe is connected to the outlet pipe, the sealing gasket can prevent water from leaking from the pipe.

[0013] Preferably, three grips are fixedly connected to the side of the second screw nut, and the ends of the three grips away from the screw are all hemispherical.

[0014] The effect achieved by the above components is that when it is necessary to rotate the second screw, the operation can be made more convenient and labor-saving by using the rotation of the second screw.

[0015] Preferably, the detection chamber is provided with three placement devices inside. Each placement device includes two slide rails, which are fixedly connected to the detection chamber. Rectangular strips are slidably connected to the inner walls of the slide rails. A rectangular frame is fixedly connected to one side of the rectangular strips that are close to each other. A plurality of hexagonal holes are opened on the lower surface of the rectangular frame. A rectangular plate is fixedly connected to one side of the rectangular frame.

[0016] The effect achieved by the above components is that different substances for filtering water can be placed in each rectangular frame of the placement device. After placement, they can be directly pushed into the detection box along the slide rail. The hexagonal holes ensure that the water leaks into the lower filtration system.

[0017] Preferably, a handle is fixedly connected to the side of the rectangular plate away from the rectangular frame, and the cross-section of the handle is U-shaped.

[0018] The effect achieved by the above components is that when it is necessary to push the rectangular frame into the detection box, the handle can be used to push it, which saves more effort and makes the operation more convenient.

[0019] Preferably, a leak-proof pad is fixedly connected to the side of the rectangular plate near the rectangular frame, and the leak-proof pad is distributed around the perimeter of the rectangular frame.

[0020] The effect achieved by the above components is that after being pushed into the testing chamber, the leak-proof pad can fit completely into the testing chamber, preventing water from splashing out of the testing chamber.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a docking device, the water source to be filtered is injected into the testing chamber through the inlet pipe. After the water source passes through multiple filtration stages and meets the standards, it needs to be transported out through the outlet pipe. At this time, the connecting pipe and the outlet pipe are placed in the middle of the retaining ring. Then, the two first screws located on the arc surface of the retaining ring are rotated. Because the first screws are threadedly connected to the retaining ring, the first screws will slowly move inward to squeeze the outlet pipe and the connecting pipe to achieve the function of fixing the pipe. After the fixing is completed, the second screw is rotated from the end of the second screw near the connecting pipe. Since the mounting plate fixedly connected to the arc surface of the retaining ring on the connecting pipe is threadedly connected to the second screw, when the second screw starts to rotate, the mounting plate will drive the retaining ring to move along the rod towards the outlet pipe. Because the first screw on the retaining ring clamps the connecting pipe, when the retaining ring moves, it will also drive the connecting pipe to move towards the outlet pipe. After moving until the connecting pipe and the outlet pipe are completely docked, the second screw is stopped, and the retaining ring stops moving. Then, the second screw is rotated in the opposite direction to loosen the connecting pipe. The sealing gasket connected to the end of the water outlet pipe away from the detection box can prevent the filtered water from leaking from the pipe connection. The handle connected to the second screw nut makes it easier and less strenuous for the operator to operate.

[0023] In this invention, by setting up a placement device, when water needs to be filtered, the water to be filtered is injected into the detection chamber through the inlet pipe. Before this, the substances to be used for filtering the water, such as biochemical cotton, nitrifying bacteria, degrading bacteria, and activated carbon, need to be placed in the rectangular frames of different placement devices according to the required filtration process. After all the substances are placed, since the rectangular strip is slidably connected to the inner wall of the slide rail, the rectangular plate can be pushed to move the rectangular frame along the slide rail into the detection chamber. At this time, the water source is injected, and the water source will pass through layers of filtration substances from top to bottom, and then leak through hexagonal holes to the next layer until the last layer. The detected water quality will then be displayed on the screen. Water that meets the standards will be delivered out through the outlet pipe. The handle plays a role in convenient operation and saving effort, and the anti-leakage pad can prevent water from splashing out from the gap between the rectangular plate and the detection chamber during the filtration process.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a water quality testing device with a multi-layer filtration structure, including a testing box 1, an inlet pipe 2, an outlet pipe 3, a connecting pipe 6, a display screen 7 for displaying water quality, and a placement device 5 for placing the water source material. A docking device 4 for connecting the outlet pipe 3 and the connecting pipe 6 is provided on one side of the testing box 1, and three placement devices 5 are provided inside the testing box 1.

[0031] The specific setup and function of the docking device 4 and the placement device 5 will be explained in detail below.

[0032] Reference Figures 2 to 4As shown in this embodiment: the docking device 4 includes a round rod 401, which is fixedly connected to one side of the detection box 1. A first circular ring rod 402 is fixedly connected to the arc surface of the round rod 401, and a second circular ring rod 410 is slidably connected to the arc surface of the round rod 401. A retaining ring 403 is fixedly connected to the lower ends of both the first circular ring rod 402 and the second circular ring rod 410. Two mounting blocks 404 are fixedly connected to the arc surface of the retaining ring 403. A first screw 405 is threadedly connected to one side of each of the two mounting blocks 404, and the first screw 405 is threadedly connected to the retaining ring 403. Two retaining rings 403 are fixedly connected to mounting plates 407 on their arc surfaces. One mounting plate 407 is rotatably connected to a second screw 408 on one side, while the other mounting plate 407 is threadedly connected to the second screw 408. An L-shaped plate 409 is fixedly connected to the side of the round rod 401 away from the detection chamber 1. The long arm end of the L-shaped plate 409 is fixedly connected to the detection chamber 1, and the connecting pipe 6 is slidably connected to the L-shaped plate 409. The short arm end of the second screw 408 is threadedly connected to the L-shaped plate 409. The two retaining rings 403 are respectively fitted onto the arc surfaces of the connecting pipe 6 and the outlet pipe 3. After the water passes through multiple filtration stages and meets the standards, it will be transported to a designated location for storage through the outlet pipe 3. At this time, rotating the second screw 408 drives the second ring rod 410 to move the connecting pipe 6 along the round rod 401 towards the outlet pipe 3 until it is fully connected to the outlet pipe 3, achieving the effect of quickly connecting and transporting the water source pipeline. One end of the first screw 405 is fixedly connected to an anti-slip pad 406, which can completely fit against the water outlet pipe 3 or the connecting pipe 6. When the connecting pipe 6 or the water outlet pipe 3 is placed in the retaining ring 403, rotating the two first screws 405 will bring the anti-slip pad 406 into contact with it, preventing the pipe from slipping out of the retaining ring 403. The end of the water outlet pipe 3 away from the detection box 1 is fixedly connected to a connecting ring 411, and the end of the connecting ring 411 away from the water outlet pipe 3 is fixedly connected to a sealing gasket 412. After the connecting pipe 6 and the water outlet pipe 3 are connected, the sealing gasket 412 can prevent water from leaking from the pipe. The side of the nut of the second screw 408 is fixedly connected to three handles 413, and the ends of the three handles 413 away from the screw are all hemispherical. When it is necessary to rotate the second screw 408, the operation can be made more convenient and labor-saving by rotating the second screw 408.

[0033] Reference Figure 5As shown in this embodiment: the mounting device 5 includes two slide rails 51, which are fixedly connected to the detection chamber 1. Rectangular strips 52 are slidably connected to the inner walls of the slide rails 51. Rectangular frames 53 are fixedly connected to the sides of the rectangular strips 52 that are close to each other. Several hexagonal holes 54 are formed on the lower surface of the rectangular frames 53. A rectangular plate 55 is fixedly connected to one side of the rectangular frames 53. Different substances for filtering water can be placed in the rectangular frames 53 of each mounting device 5. After placement, it is directly pushed into the detection chamber 1 along the slide rails 51. The hexagonal holes 54 ensure that water leaks into the lower filtration system. A handle 56 is fixedly connected to the side of the rectangular plate 55 away from the rectangular frame 53. The handle 56 has a U-shaped cross-section. When the rectangular frame 53 needs to be pushed into the detection chamber 1, the handle 56 is used to push it, saving effort and making operation more convenient. Leak-proof pads 57 are fixedly connected to the side of the rectangular plate 55 closest to the rectangular frame 53, and the leak-proof pads 57 are distributed around the rectangular frame 53. After being pushed into the testing chamber 1, the leak-proof pad 57 can fit completely into the testing chamber to prevent water from splashing out of the testing chamber 1.

[0034] Working principle: In this invention, by setting up a docking device 4, the water source to be filtered is injected into the testing chamber 1 from the inlet pipe 2. After the water source passes through multiple filtration stages and meets the standards, it needs to be transported out from the outlet pipe 3. At this time, the connecting pipe 6 and the outlet pipe 3 are placed in the center of the retaining ring 403. Then, the two first screws 405 located on the arc surface of the retaining ring 403 are rotated. Because the first screws 405 are threadedly connected to the retaining ring 403, the first screws 405 will slowly move inward to squeeze the outlet pipe 3 and the connecting pipe 6 to fix the pipes. After fixing, the second screw 408 is rotated starting from the end of the second screw 408 closest to the connecting pipe 6. Because the mounting plate 407, which is fixedly connected to the arc surface of the retaining ring 403 on the connecting pipe 6, is threadedly connected to the second screw 408, when the second screw 408 starts to rotate, the mounting plate 407 will drive the retaining ring 403 to move along the round rod 401 towards the outlet pipe 3. Since the first screw 405 on the retaining ring 403 clamps the connecting pipe 6, the movement of the retaining ring 403 will also drive the connecting pipe 6 towards the outlet pipe 3. After the connecting pipe 6 and the outlet pipe 3 are fully connected, the second screw 408 stops rotating, and the retaining ring 403 stops moving. Then, the second screw 408 is rotated in the opposite direction to loosen the connecting pipe 6. The sealing gasket 412 connected to the end of the outlet pipe 3 away from the detection box 1 can prevent the filtered water from leaking from the pipe connection. The handle 413 connected to the nut of the second screw 408 can make the operation more convenient and less strenuous for the operator.

[0035] In this invention, by setting up the placement device 5, when water needs to be filtered, the water to be filtered is injected into the detection chamber 1 through the inlet pipe 2. Before this, the substances to be used for filtering the water, such as biochemical cotton, nitrifying bacteria, degrading bacteria, and activated carbon, need to be placed in the rectangular frames 53 of different placement devices 5 according to the required filtration process. After all the substances are placed, since the rectangular strip 52 is slidably connected to the inner wall of the slide rail 51, after placement, the rectangular plate 55 can be pushed to drive the rectangular frame 53 to slide into the detection chamber 1 along the slide rail 51. At this time, the water source is injected, and the water source will pass through layers of filtration substances from top to bottom, and then leak through the hexagonal holes 54 to the next layer, until the last layer. Then the detected water quality will be displayed on the display screen 7. Water that meets the standard will be delivered out from the outlet pipe 3. The handle 56 plays a role in facilitating operation and saving effort, and the anti-leakage pad 57 can prevent water from splashing out from the gap between the rectangular plate 55 and the detection chamber 1 during the filtration process.
