Description

Technical Field

[0001] The present invention relates to the technical field of sewage detection, and in particular to a device and process for detecting sewage content in a water body. Background Art

[0002] With the acceleration of global industrialization and the development of urbanization, water pollution is becoming increasingly serious. Water pollution not only causes serious damage to the ecological environment, but also directly threatens human health and the sustainable development of society. There are many kinds of pollutants in water, including organic matter, heavy metals, nutrients, pathogens and various chemicals. These pollutants enter the water through various channels, causing water quality deterioration and ecosystem imbalance.

[0003] The necessity of water wastewater content testing is reflected in the protection of public health, environmental protection, regulatory compliance and policy formulation, industrial and agricultural development, resource management and sustainable development, emergency response and risk management, scientific research and technological innovation, social supervision and public participation, etc. Regular testing and scientific analysis can timely discover and solve water quality problems, thereby protecting the ecological environment and promoting the sustainable development of the economy and society.

[0004] For example, a Chinese patent with publication number CN119044161A discloses a device for detecting the content of microorganisms polluting the water environment and filtering water pollution; through a cleaning structure, a lifting structure, and a collecting structure, a stepper motor drives a connecting shaft 1 to rotate, thereby driving a threaded rod, a slider, and a sleeve to move, so that a cleaning brush moves above a fixed plate 1 and a filter screen 1, effectively removing debris attached to the filter screen to prevent clogging; at the same time, the stepper motor starts to drive the operation of a conical tooth 1 and a connecting shaft 2, and the screw rod and a sealing plate driven by a driving belt 2 work in coordination, the sealing plate is lifted to open the processing port, and the movement of the cleaning brush pushes the debris into the collection tank.

[0005] However, the above device still has some shortcomings in actual use: 1. The above device filters impurities in the water through the filter. However, the filter plate area is large and the water flow speed is fast near the water inlet, which causes the impurities to accumulate faster and more here, thereby affecting the water inlet effect.

[0006] 2. The cleaning brush of the above device moves over the fixed plate 1 and the filter 1 to effectively remove the debris attached to the filter. However, when encountering larger impurities, since the water flow tends to flow toward the water inlet, these impurities may be adsorbed on the filter, making it difficult for the cleaning brush to remove them; in addition, the soft brush head of the cleaning brush also seems to be powerless when facing large impurities and cannot be effectively cleaned.

[0007] Therefore, based on the above-stated viewpoints, it is of great significance to improve and perfect the above-mentioned prior art, improve the filtering efficiency of impurities, and further improve the cleaning efficiency of the filter. Summary of the invention

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0035] The embodiments of the present application disclose a device and process for detecting sewage content in a water body, which illustrates that the present invention is mainly used in the process of sewage detection, and in terms of technical effect can avoid the problem that impurities accumulate faster and more at the water inlet, thereby affecting the water intake effect of the water inlet; further, the present invention can also solve the problem that the water flow has a tendency to flow toward the water inlet, which may cause impurities to be adsorbed on the filter screen and cannot be removed by a cleaning brush. Embodiment 1:

[0036] Reference Figure 1 and Figure 2 As shown, it includes a detection box 1, a sewage pump 10 is installed on the top of the detection box 1, and water is sucked into the detection box 1 for detection through the sewage pump 10. A double-layer filter plate 11 is arranged inside the detection box 1 along its height direction. The filter plate 11 can effectively filter some solid impurities and suspended matter in the water, thereby reducing the interference of impurities on the detection results and ensuring the accuracy of water quality detection.

[0037] The filter plate 11 is slidably arranged along the length direction of the detection box 1, and a water inlet hopper 12 is slidably arranged below the filter plate 11 along the length direction of the detection box 1. A hose 13 connected to the water inlet hopper 12 is arranged below the water inlet hopper 12. A collecting chamber 14 and a detection chamber 15 are arranged at the bottom of the detection box 1 through a T-shaped plate. The end of the hose 13 away from the water inlet hopper 12 is connected to the collecting chamber 14. The screened water enters the hose 13 through the water inlet hopper 12, and then enters the collecting chamber 14 for storage through the hose 13. A water pump is arranged in the detection chamber 15, and the sewage in the collection chamber 14 can be transferred here as needed. At the same time, the detection chamber 15 is equipped with professional sewage detection equipment to meet different detection needs.

[0038] A processing box 16 is provided on one side of the detection box 1 , and a cleaning unit 2 for cleaning impurities on the filter plates 11 is provided inside the processing box 16 . A through groove corresponding to the two filter plates 11 is provided on one side of the detection box 1 close to the processing box 16 .

[0039] The filter plate 11 slides into the treatment box 16 through the groove, and impurities on the filter plate 11 are removed by the cleaning unit 2 inside the treatment box 16, and the two filter plates 11 can be cleaned separately. During the cleaning process of one of the filter plates 11, the other filter plate 11 is still filtering inside the detection box 1. There is no need to stop the filtering work during cleaning, which ensures the non-stop operation of the filtering and detection work, and improves the efficiency of sewage content detection.

[0040] Reference Figure 2 and Figure 3As shown, it is a schematic diagram of the structure that drives the water inlet bucket 12 to move; specifically, the processing box 16 is provided with a moving mechanism 3 that drives the water inlet bucket 12 to move. In the process of filtering the water body, the water flow velocity near the water inlet bucket 12 will be greater than the water flow velocity far away from the water inlet. This will cause the impurity accumulation speed on the filter screen near the water inlet to be greater than the accumulation speed far away from the water inlet during the filtering process. In the same period of time, more impurities will accumulate on the filter screen near the water inlet, blocking the filter holes of the filter screen, affecting the filtering effect and the water body entering the water inlet bucket 12. Therefore, the movable water inlet bucket 12 can adjust its position according to the actual situation. Once one side of the filter screen is blocked, the water inlet bucket 12 will automatically move to the unblocked area, thereby ensuring that the filter plate 11 can continuously and effectively filter the water body.

[0041] The moving mechanism 3 includes a reel 30 rotatably arranged on both sides of the processing box 16 , and flexible plates 31 are connected to both sides of the water inlet hopper 12 . One end of the flexible plate 31 away from the water inlet hopper 12 passes through the detection box 1 and is wound on the reel 30 .

[0042] When the reel 30 on one side rotates to wind the flexible plate 31 on the reel 30 , the water inlet bucket 12 will move toward the wound reel 30 driven by the flexible plate 31 , while the reel 30 on the other side will rotate synchronously to gradually loosen the winding of the flexible plate 31 on the other side.

[0043] The two reels 30 wind up the flexible plate 31 in opposite directions respectively and rotate synchronously through the belt. The reason for this arrangement is that when the reel 30 on one side rotates, the reel 30 on the other side will rotate synchronously. Since the two flexible plates 31 are wound in opposite directions and the reels 30 rotate in the same direction, the flexible plates 31 on the two reels 30 will have an effect of one winding up and the other loosening, ensuring the movement of the water inlet hopper 12 and ensuring that the flexible plate 31 is always kept in a taut state.

[0044] Reference Figure 5 and Figure 6 As shown, it is a schematic diagram of the structure for driving the filter plate 11 into the processing box 16 for cleaning; specifically, the cleaning unit 2 includes a pulling member 20, through which the filter plate 11 is smoothly pulled into the processing box 16. The pulling member 20 includes a pulling screw 200, two pulling screws 200 are rotatably arranged inside the processing box 16 along the length direction of the processing box 16, and a pulling plate 201 is threadedly connected to the pulling screw 200. A cross bar 202 is arranged on the side of the pulling plate 201 close to the processing box 16, and a receiving groove is opened at the bottom of the cross bar 202. A pulling block 203 is arranged inside the receiving groove through a torsion spring, and an L-shaped matching rod 204 is installed on the side of the two filter plates 11 close to the pulling plate 201.

[0045] When cleaning the filter plate 11, rotate the pull screw 200 to move the pull plate 201 closer. As the cross bar 202 on the pull plate 201 gradually approaches the matching rod 204, the pull block 203 on the cross bar 202 is driven in the reverse direction by the matching rod 204 and rotates into the storage slot. The pull plate 201 continues to move until the pull block 203 is separated from the reverse action of the matching rod 204, and the torsion spring resets the pull block 203 and makes it perpendicular to the cross bar 202 again. At this time, the pull screw 200 is driven to rotate in the reverse direction, so that the pull plate 201 gradually moves into the processing box 16. At this time, under the cooperation of the pull block 203 and the matching rod 204, the pull block 203 will pull the filter plate 11 to move during the movement of the pull plate 201 until the filter plate 11 completely enters the processing box 16.

[0046] It should be noted that the cross bar 202 may be an elastic telescopic structure. When the filter plate 11 is pulled into the processing box 16, since the filter plate 11 is restricted in the detection box 1, that is, it cannot move to the side away from the processing box 16, when the cross bar 202 approaches the matching rod 204, it will shrink, so that the pull block 203 on the cross bar 202 rotates and enters the clamping groove between the matching rod 204 and the filter plate 11. When the filter plate 11 is cleaned inside the processing box 16, it needs to be pulled out. Plate 201 pushes the filter plate 11 back to the detection box 1. Since the filter plate 11 can slide between the processing box 16 and the detection box 1 at this time, when the cross bar 202 pushes the matching rod 204, it will not drive the pull block 203 set by the torsion spring to rotate, that is, at this time the pull block 203 will not enter the clamping groove between the matching rod 204 and the filter plate 11. After the filter plate 11 is completely pushed into the detection box 1, the pull plate 201 returns to the processing box 16, and the matching rod 204 will not affect the movement of the pull plate 201.

[0047] Reference Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure for driving the filter plate 11 to flip inside the processing box 16; specifically, a flip structure 21 for driving the filter plate 11 to flip is also installed inside the processing box 16, and the flip structure 21 includes a flip shaft 210 rotatably installed in the processing box 16, and a placement plate 211 is arranged at both ends of the flip shaft 210, and a placement groove is opened on the opposite side of the placement plate 211.

[0048] By rotating the flip shaft 210, the filter plate 11 is driven to flip inside the processing box 16 so that the side with the adhering impurities faces downward, and then the impurities fall into the processing box 16, so that the filter plate 11 is cleaned. After cleaning, the filter plate 11 is driven to rotate again and the filter plate 11 is driven to return to its original direction.

[0049] The height of the flip shaft 210 corresponds to the center of the straight-line distance between the two filter plates 11. The purpose of this arrangement is that when the flip shaft 210 rotates, the filter plate 11 flips and corresponds to the through groove below, and the filter plate 11 is pushed into and pushed back into the detection box 1 by the pull plate 201. After the filter plate 11 currently being processed enters the processing box 16, the other filter plate 11 will move to the corresponding position of the through groove above under the action of other driving forces, so that the current filter plate 11 will enter the bottom of the other filter plate 11 under the push of the pull plate 201, thereby achieving that the two filter plates 11 can be cleaned separately and used alternately.

[0050] Reference Figure 7 and Figure 8 As shown, that is, a structural schematic diagram of further cleaning the filter plate 11; specifically, a vibration mechanism 22 is also provided inside the processing box 16, and the vibration mechanism 22 includes a fixed shaft 220, and the fixed shaft 220 is sleeved on the outside of the flip shaft 210, and the fixed shaft 220 is installed on the inner wall of the processing box 16, and a vibration shaft 221 is provided on the two placement plates 211 to rotate together through a volute spring, and an eccentric block 222 is provided on the vibration shaft 221, and a synchronous wheel 1 223 is provided on the vibration shaft 221, and a synchronous wheel 224 is provided on the fixed shaft 220 through a ratchet ratchet, and a synchronous belt 225 is sleeved on the synchronous wheel 1 223 and the synchronous wheel 2 224.

[0051] When the flip shaft 210 rotates, it will cause the placement plate 211 to rotate. At this time, the vibration shaft 221 on the placement plate 211 will rotate along the flip shaft 210, while the synchronous wheel 224 on the fixed shaft 220 fixed to the processing box 16 will not rotate synchronously, and will drive the synchronous wheel 1 223 on the vibration shaft 221 to rotate while rotating along the flip shaft 210. That is, during the rotation of the filter plate 11, the rotation of the flip shaft 210 causes the eccentric block 222 above it to hit the filter plate 11, driving the impurities adhered to the filter plate 11 to fall off. After the filter plate 11 is completely flipped, due to the accumulated force of the volute spring, it will cause the vibration shaft 221 to rotate in the opposite direction, and vibrate and clean the filter plate 11 again. Since the synchronous wheel 224 is set on the fixed shaft 220 through the ratchet teeth, the rotation of the vibration shaft 221 will not reversely affect the fixed shaft 220.

[0052] Reference Figure 3 and Figure 4As shown, it is a structural schematic diagram of driving another filter plate 11 to replace the upper filter plate 11 to perform filtering work; specifically, a driving member 4 for driving the two filter plates 11 to work alternately is also provided inside the detection box 1, and the driving member 4 includes a pushing block 40 slidably arranged inside the detection box 1 along the height direction of the detection box 1, and the pushing block 40 is provided in multiple groups along the length direction of the detection box 1, and the multiple pushing blocks 40 are connected by a connecting plate 41, one end of the connecting plate 41 passes through the detection box 1, and a fixing plate 42 is provided outside the detection box 1, and a spring telescopic rod 43 is provided on the fixing plate 42 along the height direction of the detection box 1, and the telescopic end of the spring telescopic rod 43 is connected to the end of the connecting plate 41 located on the outside of the detection box 1.

[0053] When the upper filter plate 11 enters the processing box 16 under the pull of the pulling plate 201 , the lower pushing block 40 will move upward under the action of the spring telescopic rod 43 , and the lower filter plate 11 will move upward under the push of the pushing block 40 .

[0054] A side of the push block 40 close to the processing box 16 is provided with an inclined surface inclined from the processing box 16 toward the detection box 1 .

[0055] When the cleaned filter plate 11 needs to be returned to the interior of the detection box 1, one side of the filter plate 11 will contact the push block 40. Under the push of the filter plate 11 and in cooperation with the inclined surface of the detection box 1, the push block 40 will move downward to facilitate the filter plate 11 to enter the interior of the detection box 1. Embodiment 2:

[0056] On the basis of the first embodiment, in order to further reduce the working cost of the present invention, we propose a linkage part 5, which can complete multiple working links through a single drive, thereby effectively reducing the purchase and maintenance costs of the equipment.

[0057] Reference Fig. 9 As shown, it is a schematic diagram of the structure that drives the flip shaft 210 to be linked with the reel 30; specifically, a linkage pulley 50 is provided on both the reel 30 and the flip shaft 210 through ratchet teeth, and a linkage belt 51 is commonly sleeved on the linkage pulley 50, and a motor (not shown in the figure) is installed on the processing box 16, and the output shaft of the motor is connected to the linkage pulley 50 on the flip shaft 210.

[0058] When the output shaft of the motor rotates in the forward direction, it drives the linked pulley 50 connected thereto to rotate, thereby rotating the flip shaft 210. At the same time, the linked pulley 50 on the reel 30 also rotates synchronously, but does not cause the reel 30 to rotate. On the contrary, when the output shaft of the motor rotates in the reverse direction, it drives the reel 30 to rotate, while the flip shaft 210 remains stationary. In this way, a single drive can realize the control of multiple working units. Embodiment three:

[0059] On the basis of the second embodiment, in order to further improve the perfection of the present invention, a protective member 6 is also proposed, which is conducive to blocking the through groove during the movement of the filter plate 11, thereby preventing the water inside the detection box 1 from flowing into the treatment box 16 through the through groove during the movement of the filter plate 11.

[0060] Reference Figure 8 As shown, it is a schematic diagram of the structure for blocking the through groove; specifically, the protective member 6 includes a protective plate 60, and the protective plate 60 is hinged to the bottom of the filter plate 11 in an equidistant manner along the length direction of the filter plate 11.

[0061] During the movement of the filter plate 11, the protective plate 60 will be perpendicular to the filter plate 11 to block the through groove. When the protective plate 60 moves to the through groove position along with the filter plate 11, it will automatically rotate under the reaction force of the inner wall of the through groove, thereby not hindering the movement of the filter plate 11.

[0062] During operation: In the first step, water is sucked into the detection box 1 through the sewage pump 10, and some solid impurities in the water are filtered and screened using the filter plate 11 to reduce the interference of these impurities on the detection results.

[0063] Step 2: The screened water passes through the water inlet hopper 12 and enters the hose 13, and then enters the collection chamber 14 for storage. The sewage in the collection chamber 14 is transferred to the detection chamber 15 by a water pump, and the water in the detection chamber 15 is tested using professional equipment.

[0064] Step 3: When cleaning the filter plate 11, drive the pulling screw 200 to rotate. When the pulling screw 200 rotates, the pulling plate 201 approaches the filter plate 11. At the same time, the pulling block 203 on the cross bar 202 is driven in the reverse direction and rotates into the storage groove during the process of approaching the matching rod 204. With the gradual movement of the pulling plate 201, once the pulling block 203 loses the reverse force of the matching rod 204, it automatically returns to its initial state under the elastic force of the torsion spring, that is, perpendicular to the cross bar 202. At this time, the pulling screw 200 is used to move the pulling plate 201 into the processing box 16. At this time, with the cooperation of the pulling block 203 and the matching rod 204, the filter plate 11 is pulled into the processing box 16.

[0065] Step 4: The filter plate 11 is flipped inside the processing box 16 by driving the flip shaft 210 to rotate, so that the side of the filter plate 11 adhering to the impurities faces downward. When the flip shaft 210 rotates, the vibration shaft 221 on the placement plate 211 is driven to not only rotate along its trajectory, but also rotate at the same time, so that the eccentric block 222 above it will knock the filter plate 11, driving the impurities adhering to the filter plate 11 to fall off. After the filter plate 11 is completely flipped, due to the stored force of the volute spring, it will drive the vibration shaft 221 to rotate in the opposite direction, and vibrate and clean the filter plate 11 again.

[0066] Step 5: After the filter plate 11 is cleaned inside the processing box 16 , the filter plate 11 is pushed back into the detection box 1 using the pull plate 201 .

[0067] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0068] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
