Description

Technical Field

[0001] The present invention relates to the technical field of wastewater collection and detection, and in particular to detection equipment capable of collecting and detecting wastewater at different depths and a method for using the same. Background Art

[0002] With the rapid development of industrialization and urbanization, the problem of wastewater discharge is becoming increasingly serious, posing a serious threat to the ecological environment and human health. As an important part of environmental protection, the development and application of wastewater collection and testing technology are particularly important. Wastewater collection and testing aims to accurately and quickly detect and analyze pollutants in wastewater through scientific methods and technical means, providing a reliable basis for wastewater treatment, discharge supervision and environmental management.

[0003] Wastewater pool is an important part of wastewater collection and treatment system, which has the functions of wastewater storage and pretreatment.

[0004] The traditional method of collecting wastewater in wastewater pools is relatively simple, and can only collect samples from the wastewater surface or a fixed depth. However, the concentration and type of pollutants in the wastewater often change with the depth. Sampling and testing at a single depth cannot fully reflect the overall pollution status of the wastewater. Moreover, the collection and sampling cannot be automated. Manual operation of equipment is required to collect from multiple wastewater pools, and it is difficult to collect from different locations of the same wastewater pool during collection. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the collection method in the prior art is relatively single and can only collect samples from the wastewater surface or a fixed depth.

[0018] The method for using the detection equipment capable of collecting and detecting wastewater at different depths specifically includes the following steps:

[0019] S1. Start two large winches, causing the reel drums in the two large winches to reel in and unreel, respectively, so that the collection device is pulled along the steel pole to a corresponding position by the traction of the rope;

[0020] S2. Start the hydraulic cylinder in the lowering mechanism, and drive the four collecting cylinders in the collecting mechanism to move into the sewage tank through the piston rod;

[0021] S3. Start the small winch. The rope on the outer wall of the winding drum in the small winch is unwound, causing the pull plate and multiple collection barrels to be gradually lowered. The multiple collection barrels fall to different depths. Then, the wastewater flows through the water inlet hole into the corresponding collection bottle for collection;

[0022] S4, then reversely drive the small winch to move the pull plate connected to the multiple collection cylinders upward in sequence for reset, and the water inlet hole will be blocked during the reset process;

[0023] S5. Then the hydraulic cylinder is driven to reset the entire collection mechanism, and then the collection equipment is moved to the next location for collection through the cooperation of two large winches. Every time the collection cylinder falls and resets, the internal placement rack will rotate, so that the next collection bottle is connected to the water inlet, so as to realize wastewater collection in different areas.

[0024] S6. Take out multiple collection bottles together with the placement rack by opening the baffle, and then test the samples using a multi-parameter water quality online detector, thereby completing the sampling and testing operations of the wastewater.

[0025] In the present application, during specific use, the pillars are successively erected on the edges of multiple sewage pools, and the ropes on the outer walls of the winding drums in the two large winches are connected to the two traction rings on the sides of the collecting device. The collecting device is pulled to each sewage pool and different positions in the sewage pool by winding and unfolding the ropes, and a limiting ring is provided on the outer wall of the rope to limit the rope. When the collecting device is moved to the collection point inside the first sewage pool, the entire lower collecting mechanism is lowered to the inner surface of the sewage pool by driving the hydraulic cylinder, and then the small winch is driven to lower the pull plate by unfolding the rope. The pull plate falls through the slider and the chute, and then multiple collecting barrels will gradually fall until the slider slides from the top position of the chute to the bottom end, so that it moves to waters of different depths, reference Figure 4 After the multiple collecting cylinders are unfolded, the corresponding water inlet holes will leak out, and then the wastewater will enter the interior of the collecting bottle through the water inlet holes and the connecting holes to achieve collection of wastewater at different depths. Then the small winch will be driven again to reel in the rope, and the extension will pull the pull plate up to the side of the lowest collecting cylinder, and the pull plate will also seal the water inlet hole. At this time, the corresponding slider will move to the top of the slide, and then the pull plate will continue to be pulled and move upward together with the lowest collecting cylinder, and move the side of the next collecting cylinder to achieve the sealing of the water inlet and continue to move until all move to their original positions. In order to ensure that the placement rack inside the cylinder rotates during the next movement so that the next collection bottle is connected to the water inlet hole, so as to continue to collect the wastewater inside the next sewage pool, it will be achieved through the chassis at the bottom of the cylinder. When the collection equipment is in Figure 3 When the pull plate and the collecting cylinder are to be reeled and reset, the limit rod will move upward and pass through the trough again to enter the inside of the annular corrugated groove, driving the chassis to continue rotating, so that the placing rack will continue to rotate, and the bottom end of the communicating hole will be located between the two collecting bottles again, and this action will be repeated when it falls next time, so that a new collecting bottle will be connected to the communicating hole after each fall and rise, so as to collect the waste water inside the next sewage pool, and in order to ensure that the chassis is unidirectional rotation, the limit rod will not return along the original path when moving. Figure 10 For example, the bottom end of the trough is located on the right side of the top end of the trough, and the bottom end of the crest is located on the left side of the top end of the crest, thereby solving the problem of the limit rod returning to its original position.

[0026] In the present invention, the detection device capable of collecting and detecting wastewater at different depths can drive two large winches to reel and unfold the rope through a transmission mechanism, thereby moving the collection device to different sewage pools and different positions inside the sewage pools, thereby realizing the displacement of the collection device, so as to achieve the relatively automatic movement of the collection device to different positions inside multiple sewage pools for wastewater collection, thereby reducing labor and increasing actual efficiency.

[0027] In the present invention, the detection device capable of collecting and detecting wastewater at different depths can achieve the goal of, after the collection device is moved to a corresponding position by a transmission mechanism, being able to automatically move downward to the interior of a sewage pool for collection work, and being able to collect wastewater from areas of different depths at one time. At the same time, the collection bottle inside the collection device can automatically change position, so that it can continue to collect wastewater from the interior of the next sewage pool;

[0028] In the present invention, when in use, the collection device can be gradually moved to multiple sewage pools through the transmission mechanism, and can be moved to different positions for collection work, thereby avoiding the need for manual use of equipment to perform collection work one by one;

[0029] After that, the collection device moves it to the designated position and it can move downward on its own to collect wastewater. The collection mechanism inside the collection device can collect wastewater from different depths. There is no need to collect wastewater from the next depth again after a single collection, thereby increasing the actual work effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0043] Reference Figure 3This device, capable of collecting and testing wastewater at varying depths, is used in the field of wastewater collection and testing. It includes a multi-parameter online water quality detector 40, which can test collected wastewater. It also includes a collection device 2, which includes a lowering mechanism and a collection mechanism 13. The lowering mechanism is key to enabling the collection device 2 to penetrate deep into the sewage tank 5 and perform its wastewater collection task. It primarily consists of a top cover 10 and at least one (typically multiple for more stable support and balance) hydraulic cylinder 11. The collection mechanism 13 includes a connecting cover 15 and four collection barrels 16. The hydraulic cylinder 11 is mounted on the bottom of the top cover 10, with the end of its piston rod fixed to the top of the connecting cover 15. The collection mechanism 13 is the component that actually performs the wastewater collection task. Its design fully considers collection efficiency, capacity, and ease of operation. The four collection barrels are evenly distributed below the connecting cover. Each collection barrel has sufficient capacity and corrosion resistance to accommodate and store wastewater collected from the sewage tank.

[0044] Specifically, after the collecting device 2 is moved to the designated position, the entire collecting mechanism 13 below is dropped to the inner surface of the sewage pool 5 by driving the hydraulic cylinder 11. The limiting telescopic rod 12 is a sliding rod and a sliding cylinder slidably sleeved on the outer wall of the sliding rod. The ends of the sliding rod and the sliding cylinder that are away from each other are respectively fixed on the top of the connecting cover 15 and the bottom of the top cover 10, which are used to ensure the vertical displacement of the collecting device.

[0045] Reference Figure 4 The collecting mechanism 13 also includes a pull plate 19. A plurality of collecting cylinders 16 and the pull plate 19 are slidably connected through a connecting assembly. A collecting cylinder 16 at the top is fixedly arranged at the bottom of the connecting cover 15. A collecting cylinder 16 at the bottom is connected to the pull plate 19. The connecting assembly includes four No. 1 connecting plates 17 and three No. 2 connecting plates 18. The four No. 1 connecting plates 17 are respectively fixed on the outer walls of the four collecting cylinders 16. The three No. 2 connecting plates 18 are respectively fixed on the outer walls of the three collecting cylinders 16 at the bottom. Sliders 31 are provided on the tops of the sides of the No. 2 connecting plates 18 and the pull plate 19. A slide groove 30 is opened on the side of the No. 1 connecting plate 17. The plurality of slides 31 respectively cooperate with the plurality of slide grooves 30.

[0046] A small winch 7 is fixedly installed on the top of the connecting cover 15 , and a rope on the outer wall of the winding drum of the small winch 7 is fixedly installed on the top of the pulling plate 19 through the through hole 14 .

[0047] Specifically, following the previous step, when the collecting mechanism 13 falls to the inner surface of the sewage pool 5, the small winch 7 is driven to lower the pull plate 19, and the pull plate 19 falls through the slider 31 and the chute 30. After that, multiple collecting cylinders 16 will gradually fall until the slider 31 slides from the top position of the chute 30 to the bottom end, so that it moves to the reference water area of different depths. Figure 4 ;

[0048] Reference Figure 7-9 The collecting cylinder 16 includes a cylinder 20 and a baffle 22 hingedly arranged on one side of the cylinder 20. The inner cavity 25 inside the collecting cylinder 16 is provided with a placement rack 23. Four collecting bottles 21 are placed inside the placement rack 23. A water inlet 28 is opened on one side of the No. 1 connecting plate 17. A connecting hole 29 is opened on the outer wall of the cylinder 20 to communicate with the inner cavity 25 and the water inlet 28. When the multiple collecting cylinders 16 are unfolded, the corresponding water inlet 28 will leak out, and then the wastewater enters the interior of the collecting bottle 21 through the water inlet 28 and the connecting hole 29. Now collect to achieve the wastewater collection effect at different depths, then re-drive the small winch 7 to reel in the rope, and the extension will pull the pull plate 19 up to the side of the lowest collection cylinder 16, and the pull plate 19 will also block the water inlet 28. At this time, the corresponding slider 31 will move to the top of the inside of the slide 30, and then will continue to pull the pull plate 19 and move upward together with the lowest collection cylinder 16, and move the side of the next collection cylinder 16 to achieve the blocking of the water inlet 28 and continue to move until all move to their original positions.

[0049] Reference Figure 7-8 A groove is provided at the bottom of the cylinder 20, and a chassis 27 is rotatably provided inside the groove. A connecting rod 26 is fixedly provided on the top of the chassis 27. The top end of the connecting rod 26 rotates and penetrates into the interior of the inner cavity 25. A rectangular block 24 is fixedly provided on the top end of the connecting rod 26. A limiting groove 32 is provided at the bottom of the placement rack 23, and the limiting groove 32 cooperates with the rectangular block 24.

[0050] Specifically, the rectangular block 24 enables the placement rack 23 to rotate together with the base plate 27 when the base plate 27 rotates, so that the collecting bottle 21 placed inside the placement rack 23 can move after the base plate 27 rotates.

[0051] Reference Figure 6-8 In order to ensure that the placement rack 23 inside the cylinder 20 rotates during the next movement so that the next collection bottle 21 is connected to the water inlet 28, so as to continue to collect the wastewater inside the next sewage pool 5, the outer wall of the chassis 27 is provided with an annular corrugated groove 33, and the bottom of the three No. 2 connecting plates 18 and the bottom of the pull plate 19 are fixedly provided with a vertical plate 35. A limiting rod 36 is fixedly provided on one side of the vertical plate 35, and the four limiting rods 36 are respectively matched with the four annular corrugated grooves 33.

[0052] Specifically, when the collecting device 2 is in Figure 3When the plurality of collecting cylinders 16 and the pull plate 19 fall down, the limiting rod 36 will be driven to move downward, and the annular corrugated groove 33 will realize the rotation of the chassis 27. The rotation of the chassis 27 will drive the rectangular block 24 to rotate through the connecting rod 26, and the rectangular block 24 will drive the placement rack 23 to rotate. At this time, the collecting bottle 21 will rotate with the connecting rod 26. The bottom end of the through hole 29 is connected. When the pull plate 19 and the collecting cylinder 16 are to be reeled and reset, the limit rod 36 will move upward and pass through the trough 34 again to enter the interior of the annular corrugated groove 33, driving the chassis 27 to continue to rotate, causing the placement rack 23 to rotate, and the bottom end of the connecting hole 29 to be re-located between the two collecting bottles 21. When it falls next time, this action will continue to be repeated, so that after each fall and rise, the new collecting bottle 21 will be connected to the connecting hole 29 to collect the wastewater inside the next sewage pool 5.

[0053] In order to ensure that the chassis 27 can stably and reliably realize unidirectional rotation, that is, to ensure that its rotation direction is accurately controlled and will not be accidentally reversed during driving or operation, a limit rod 36 is provided with a specific waveform track (such as Figure 10 The interactive mechanism (as shown) solves the problem of the limit rod 36 returning to its original position. The bottom end of the trough 34 is located to the right of the top of the trough 34, and the bottom end of the crest 37 is located to the left of the top of the crest 37. This waveform track design essentially creates a "one-way channel" for the limit rod 36, so that it can only move in the predetermined direction and cannot return in the reverse direction.

[0054] The steps for using the detection equipment that can collect and detect wastewater at different depths are as follows:

[0055] S1. Start the two large hoists 1 so that the reel drums in the two large hoists 1 perform reeling and unreeling operations respectively, so that the collecting device 2 is pulled along the steel rod 4 to the corresponding position by the traction of the rope;

[0056] S2. Start the hydraulic cylinder 11 in the lowering mechanism, and drive the four collecting cylinders 16 in the collecting mechanism 13 to move into the sewage tank 5 through the piston rod;

[0057] S3. Start the small hoist 7. The rope on the outer wall of the winding drum of the small hoist 7 is unwound, causing the pull plate 19 and the multiple collection drums 16 to be gradually lowered. The multiple collection drums 16 fall to different depths. Then, the wastewater flows through the water inlet 28 to the corresponding collection bottle 21 for collection;

[0058] S4, then reversely drive the small winch 7 to move the pull plate 19 connected to the multiple collecting cylinders 16 upward in sequence for reset, and the water inlet hole 28 will be blocked during the reset process;

[0059] S5. Then, the hydraulic cylinder 11 is driven to reset the entire collection mechanism 13, and then the collection device 2 is moved to the next location for collection through the cooperation of the two large winches 1. Each time the collection cylinder 16 falls and resets, the internal placement rack 23 will rotate, so that the next collection bottle 21 is connected to the water inlet 28, so as to realize wastewater collection in different areas.

[0060] S6. The plurality of collecting bottles 21 and the placement rack 23 are taken out by opening the baffle 22, and then the samples are tested using the multi-parameter water quality online detector 40, thereby completing the wastewater sampling and testing operations. Example 2

[0061] refer to Figure 1-2 , improved on the basis of Example 1: In order to realize automation, reduce the number of steps for workers to operate, and to be able to collect wastewater at different positions in the sewage pool 5, a transmission mechanism is set. The transmission mechanism is first composed of a plurality of pillars 3. These pillars are evenly distributed around the sewage pool 5 in a semicircular shape, ensuring the stability and load-bearing capacity of the entire transmission system. A high-strength steel rod 4 is hung on the top of the pillar. This steel rod not only serves as the core skeleton of the transmission system, but also undertakes multiple functions such as suspension and guidance, providing a solid foundation for subsequent automated operations. In order to realize the flexible movement and Positioning, design and install a rotating hanging ring 8, both ends of the steel rod 4 are fixed with a limit ring 6, the limit ring 6 is set on the outer wall of the rope, the transmission mechanism also includes two large winches 1, the two winches are installed in appropriate positions, the strong ropes wrapped on their winding drums pass through the limit ring 6 and are tightly connected with the two traction rings 9. When the winch is started, the rope can be retracted and released to drive the top cover to move smoothly along the preset trajectory without manual intervention, which greatly improves the working efficiency and safety. The protective plate 38 rotatably set at the open end of the hanging ring 8 can keep the hanging ring 8 in a closed state during normal movement to prevent it from falling. Figure 2 When passing through the connection point between the pillar 3 and the steel rod 4, it can rotate to allow the hanging ring 8 to pass smoothly. A torsion spring is provided at the rotation point between the protective plate 38 and the hanging ring 8, which can achieve the effect of automatic reset after the protective plate 38 rotates, and a ball 39 is provided on the inner wall of the hanging ring 8 to reduce friction.

[0062] Specifically, the pillars 3 are erected on the edges of multiple sewage pools 5 in sequence, and the ropes on the outer walls of the winding drums in the two large winches 1 are connected to the two traction rings 9 on the sides of the collecting device 2. The collecting device 2 is pulled to move to each sewage pool 5 and different positions within the sewage pool 5 by winding and unfolding the ropes, so as to reduce labor and increase actual efficiency.

[0063] Through the transmission mechanism, it is possible to drive two large winches to reel and unfold the rope, move the collection equipment to different sewage pools and different positions inside the sewage pools, and realize the displacement of the collection equipment, so as to achieve the relatively automatic movement of the collection equipment to different positions inside multiple sewage pools for wastewater collection, thereby reducing labor and increasing actual efficiency;

[0064] Through the collection device, after the collection device is moved to the corresponding position through the transmission mechanism, it can move downward to the inside of the sewage pool to perform collection work, and can collect wastewater from different depth areas at one time. At the same time, the collection bottle inside the collection device can automatically change its position, so that it can continue to collect wastewater inside the next sewage pool.

[0065] After wastewater collection and sampling, this key step marks the official start of the monitoring and evaluation link in the wastewater treatment process. The wastewater is tested using a multi-parameter water quality online detector. As an outstanding representative of modern water quality monitoring technology, the multi-parameter water quality online detector has advanced design concepts and powerful functions. It can integrate the detection functions of multiple water quality parameters on a single device, greatly improving the detection efficiency and accuracy.

[0066] The core advantage of this detector lies in its versatility and real-time performance. It can simultaneously and quickly measure multiple key indicators in water bodies, including but not limited to basic and important water quality parameters such as pH value, dissolved oxygen, conductivity, turbidity, etc., pH value (used to evaluate the acid-base balance of water bodies), dissolved oxygen (an important indicator reflecting the respiration and self-purification capacity of organisms in water bodies), conductivity (indirectly indicating changes in ion concentration in water bodies), turbidity (an intuitive parameter for measuring water clarity). These parameters are of direct and important significance for evaluating the pH value, dissolved gas content, ion concentration and suspended matter content of water bodies.

[0067] In addition, the multi-parameter online water quality detector can also deeply detect some more complex and critical water quality indicators, such as COD (chemical oxygen demand), ammonia nitrogen, total phosphorus, and total nitrogen. COD (chemical oxygen demand, used to measure the content of organic pollutants in water bodies), ammonia nitrogen (a key indicator for assessing the risk of eutrophication of water bodies), total phosphorus, and total nitrogen (both important parameters for controlling nutrient pollution in water bodies) are important indicators for measuring the degree of organic pollution and nitrogen and phosphorus nutrient pollution in water bodies. They play a decisive role in determining whether wastewater meets discharge standards, whether further treatment is required, and the treatment effect. They provide strong support for the timely adjustment and optimization of the wastewater treatment process. At the same time, online monitoring data can also be automatically recorded, stored, and transmitted to a remote monitoring center, facilitating remote monitoring and data analysis by management personnel, further improving the intelligent level and management efficiency of wastewater treatment.

[0068] However, as is well known to those skilled in the art, the working principles and wiring methods of the large winch 1, the small winch 2 and the hydraulic cylinder 11 are commonplace, and are conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0069] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
