Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a water quality detector for seagrass seedling cultivation. Background Technology

[0002] Seagrass, as a key component of nearshore marine ecosystems, possesses multiple ecological values, including carbon sequestration and oxygen release, water purification, shoreline protection and disaster mitigation, and providing habitats and breeding grounds for marine life. In recent years, seagrass bed ecological restoration and large-scale artificial seedling cultivation have gradually emerged, becoming one of the core tasks in marine ecological protection and restoration. Seagrass seedling cultivation is extremely sensitive to the aquatic environment. Even slight fluctuations in water quality indicators such as water temperature, salinity, pH, dissolved oxygen, ammonia nitrogen, and nitrite can directly affect the germination rate of seagrass seeds, seedling growth, and survival rate, and may even lead to root rot, bleaching, and death of seedlings. Therefore, real-time, accurate, and comprehensive monitoring of the water quality in the seedling cultivation ponds is a crucial prerequisite for ensuring the effectiveness of seagrass seedling cultivation and achieving large-scale, standardized seedling cultivation.

[0003] Currently, most conventional water quality testing equipment on the market, as well as existing water quality detectors for seagrass seedling cultivation, adopt a fixed installation design. The main body of the equipment or the detection probe is mostly attached to or fixed to the wall of the seagrass seedling pond, relying on single-point deployment to collect water quality data. Although this type of traditional testing equipment can meet the basic testing needs of small water bodies and simple seedling cultivation scenarios, it has obvious technical limitations in large-scale, large-area seagrass seedling cultivation operations and is difficult to adapt to the actual seedling production needs.

[0004] On the one hand, existing fixed water quality detectors have an extremely limited detection range, only able to collect water quality data from a small area around the probe, and cannot cover the entire water body of the seedling pond; on the other hand, large-scale seagrass seedling ponds generally have the characteristics of large water area and wide water body distribution. Affected by factors such as water flow, seedling substrate deposition, uneven seedling density distribution, and light differences, water quality indicators in different areas and water layers within the pond are prone to stratification and differential distribution. Data obtained from single-point pond wall detection can only represent the water quality status of a local water body and cannot objectively and comprehensively reflect the overall water quality environment of the seedling pond.

[0005] On the other hand, relying on data from single-point pool wall monitoring for water quality control is prone to deviations. Problems such as local water quality meeting standards but distant water indicators exceeding standards, excessive nutrients or pollution accumulation in local water bodies are difficult to detect in a timely manner. This not only fails to provide a stable and suitable overall growth environment for seagrass seedling cultivation, but also increases water quality control costs, reduces seedling management efficiency, and may even lead to seedling losses due to inaccurate water quality assessments and untimely control, thus hindering the efficient development of the large-scale seagrass seedling industry. Summary of the Invention

[0006] Given that existing technologies have problems such as fixed single-point deployment, limited detection range, and the ability to collect local water body data, which cannot reflect the overall water quality of the seedling pond, and are prone to causing water quality control deviations, increasing control costs, reducing seedling management efficiency, and being difficult to adapt to the needs of large-scale seagrass seedling operations, a water quality detector for seagrass seedling detection is proposed.

[0007] This application provides a water quality detector for seagrass seedling cultivation, the purpose of which is to: overcome the technical limitations of traditional fixed detection equipment, realize real-time accurate and comprehensive monitoring of water quality in the entire area and multiple water layers of the seedling pond, objectively reflect the overall water quality environment, avoid deviations in water quality control, reduce water quality management costs, improve seedling management efficiency, provide a stable and suitable water environment for seagrass seed germination and seedling growth, ensure the survival rate and growth of seagrass seedlings, and promote the efficient development of the large-scale and standardized seagrass seedling cultivation industry.

[0008] The technical solution of the present invention is as follows: a water quality detector for seagrass seedling testing, comprising a housing, a detection head disposed at the bottom of the housing, a fixing frame disposed at the top of the housing, the detection head comprising a box disposed at the bottom of the housing, a detection port opened on the side of the box, an equipment slot opened at the top of the box, two detection rods disposed between the detection port and the equipment slot, the detection head further comprising an impeller disposed inside the detection port, a drive motor disposed inside the equipment slot, a drive wheel disposed outside the output shaft of the drive motor, a connecting groove opened between the equipment slot and the detection port, and a transmission wheel disposed inside the connecting groove.

[0009] The impeller is located on the side of the detection rod. A slot is opened on the outer side of the impeller to mesh with the drive wheel. The drive wheel meshes with the drive wheel. When the impeller rotates forward, it generates a thrust in the direction of the detection rod. After the drive motor starts, it first rotates in reverse and then in forward. The time ratio of the reverse rotation to the forward rotation is 1:2. A flow guide component is provided in the detection port.

[0010] Furthermore, the drainage component includes a frame mesh disposed at the opening of the detection port and a guide plate disposed within the frame mesh.

[0011] Furthermore, the drainage assembly also includes a first mating tooth disposed on the side of the frame mesh near the impeller, a second mating tooth disposed on the side of the impeller near the frame mesh, and a rotating wheel disposed inside the detection port.

[0012] The first mating tooth is arranged in a half circle along the outline of the frame mesh, and the second mating tooth is arranged in a full circle along the outline of the impeller. The rotating wheel meshes with the first and second mating teeth.

[0013] Furthermore, the frame mesh is rotatably installed inside the detection port, and a limiting platform is provided between the two, with a reset spring provided on the outside of the limiting platform.

[0014] Furthermore, the diversion assembly also includes two push blocks disposed on the side of the frame mesh near the impeller, two rotating shafts disposed on the top of the rotating wheel, and a baffle disposed on the outside of the rotating shafts.

[0015] The lever is arc-shaped, with its inner arc side facing the central axis of the rotating wheel. The maximum angle at which the lever rotates away from the central axis of the rotating wheel does not exceed 90 degrees. A torsion spring is provided between the lever and the rotating shaft. Two push blocks are located at both ends of the distribution area of ​​the mating teeth and correspond to the two levers.

[0016] Furthermore, a cleaning component is provided inside the detection port. The cleaning component includes an adjustment groove formed on the inner wall of the detection port, a screw rod disposed inside the adjustment groove, a sliding sleeve disposed on the outside of the screw rod, a cleaning sleeve disposed on the outside of the two detection rods, and a connecting rod disposed between the sliding sleeve and the two cleaning sleeves.

[0017] The adjusting groove extends upwards into the equipment groove, the screw extends into the machine housing, and the sliding sleeve and the screw are threadedly connected.

[0018] Furthermore, the cleaning component also includes a scraping sleeve disposed at the bottom of the cleaning sleeve, the lower end of which is tapered.

[0019] Furthermore, the cleaning component also includes grooves arranged in a linear array on the outer side of the cleaning sleeve, a pressure ring disposed on the outer side of the grooves, and an elastic strip disposed on the inner side of the pressure ring.

[0020] The groove is located at the upper end of the tapered surface at the lower end of the cleaning sleeve, and the elastic strip is located in one of the grooves.

[0021] Furthermore, the fixing frame includes a top sleeve disposed on the top of the housing, a first upright disposed on the top of the top sleeve, a first connecting platform disposed on the outside of the first upright, a horizontal bar passing through the side of the first connecting platform, a second connecting platform disposed on the outside of the horizontal bar, a second upright disposed through the bottom of the second connecting platform, and a clamping plate disposed on the bottom of the second upright. Both the first connecting platform and the second connecting platform have horizontal holes and vertical holes on their outer sides.

[0022] The first upright is located in the vertical hole of the first connecting platform, the second upright is located in the vertical hole of the second connecting platform, and the horizontal bar passes through the horizontal holes of the first connecting platform and the second connecting platform.

[0023] Furthermore, the fixing frame also includes a mounting hole inside the connecting platform, a pressure bar and a pressure spring disposed inside the mounting hole, and a pressure relief hole opened on the outside of the crossbar.

[0024] The pressure strip is located between the horizontal bar and the second vertical bar, and the pressure relief hole and the pressure strip are located on the same horizontal plane.

[0025] The beneficial effects of this invention are as follows: 1. By setting an impeller, during detection, the drive motor drives the impeller to rotate, and the impeller pushes the water flow so that water from a distance can also flow through the detection port. In this way, multiple sets of data can be detected by the detection rod, corresponding to the water flow at different locations, thereby making a more comprehensive judgment on the water quality in the seedling pond and improving the efficiency of seedling management. At the same time, the working program of the drive motor is set to first reverse and then forward, so that the water flow is first guided to flow away from the seedling pond wall, pushing away the debris located at the opening of the detection port, and preventing these debris from blocking the inlet of the detection port during detection, thus affecting the water flow through the detection port.

[0026] 2. By setting a rotating wheel, when the impeller rotates in reverse, it drives the frame mesh to rotate 180 degrees, and guides the water flow in one direction into the detection port through the guide plate. When the impeller rotates in the forward direction, it drives the frame mesh to rotate 180 degrees, and guides the water flow in the other direction into the detection port through the guide plate. In this way, the water flow is divided into two paths, avoiding the backflow of raw water and affecting the water quality analysis results.

[0027] 3. By setting up a fixed frame, the horizontal bar can slide within the second connecting platform to adjust the distance between the machine casing and the seedling pond wall. The vertical bar can slide within the second connecting platform to adjust the depth of the machine casing inserted into the water surface. This allows for quick adjustment of the detection position, making the equipment more convenient to use and obtaining better detection results.

[0028] 4. By setting a pressure bar, the pressure bar will apply an additional resistance to the second upright, making it better resist the weight of the equipment and keep it stable during testing. At the same time, the resistance generated by the pressure bar will disappear during adjustment. This not only facilitates adjustment, but also avoids serious wear of parts due to excessive friction during adjustment, which would affect the stability and service life of the equipment.

[0029] 5. By setting up a cleaning component, when the surface of the detection rod becomes covered with deposits after the equipment has been used for a period of time, the adjusting motor is started, the screw controls the movement of the sliding sleeve, and the sliding sleeve controls the cleaning sleeve to slide on the surface of the detection rod to scrape off the deposits. This can reduce detection interference and improve the accuracy of the equipment. Attached Figure Description

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] Example 1, referring to Figures 1-16 The first embodiment of the present invention provides a water quality detector for seagrass seedling testing, including a housing 1, a detection head 2 disposed at the bottom of the housing 1, and a fixing frame 3 disposed at the top of the housing 1. The detection head 2 includes a box 21 disposed at the bottom of the housing 1, a detection port 22 opened on the side of the box 21, an equipment slot 23 opened at the top of the box 21, and two detection rods 24 disposed between the detection port 22 and the equipment slot 23. The detection head 2 also includes an impeller 25 disposed inside the detection port 22, a drive motor 26 disposed inside the equipment slot 23, a drive wheel 27 disposed outside the output shaft of the drive motor 26, a connecting groove 28 opened between the equipment slot 23 and the detection port 22, and a transmission wheel 29 disposed inside the connecting groove 28.

[0049] Specifically, the housing 1 and the detection head 2 are ultrasonically welded together. The housing 1 houses the main control circuit board, which connects to control the two detection rods 24 and the drive motor 26. In use, the housing 1 is inserted into the seedling tank, the detection head 2 is submerged in the water, and then it is hung against the tank wall using the fixing bracket 3. The box 21 is circular and passes through the detection head 2. The equipment slot 23 communicates with the internal space of the housing 1. The length of the detection rod 24 within the detection port 22 exceeds the radius of the detection port 22. The detection port 22 has a rotating groove corresponding to the impeller 25, allowing the impeller to rotate. The impeller 25 rotates within the detection rod 24. The drive motor 26 is fixed in the equipment slot 23 by a positioning frame. The drive wheel 27 is engaged with the drive motor 26. The outer side of the impeller 25 has a slot that meshes with the transmission wheel 29. The transmission wheel 29 is rotatably installed in the connecting slot 28. The transmission wheel 29 meshes with the drive wheel 27. When the impeller 25 rotates forward, it generates a thrust toward the detection rod 24. After the drive motor 26 starts, it first rotates in reverse and then in forward. The time ratio of the reverse and forward rotation is 1:2. A flow guide assembly 4 is provided in the detection port 22.

[0050] By setting the impeller 25, during detection, the drive motor 26 drives the impeller 25 to rotate, and the impeller 25 pushes the water flow so that the water flow from a distance can also flow through the detection port 22. In this way, multiple sets of data can be detected by the detection rod 24, corresponding to the water flow at different locations, so as to make a more comprehensive judgment on the water quality in the seedling pond and improve the efficiency of seedling management. At the same time, the working program of the drive motor 26 is set to first reverse and then rotate forward, so that the water flow is first guided to flow away from the seedling pond wall, pushing away the debris located at the opening of the detection port 22, so as to prevent these debris from clogging the inlet of the detection port 22 during detection and affecting the water flow through the detection port 22.

[0051] The drainage component 4 includes a frame mesh 41 disposed at the opening of the detection port 22, and a guide plate 42 disposed within the frame mesh 41.

[0052] The flow-guiding assembly 4 also includes a first mating tooth 43 disposed on the side of the frame mesh 41 near the impeller 25, a second mating tooth 44 disposed on the side of the impeller 25 near the frame mesh 41, and a rotating wheel 45 disposed inside the detection port 22.

[0053] Specifically, the frame mesh 41 is rotatably installed inside the detection port 22. The guide plate 42 is inclined at a 45-degree angle to the central axis of the frame mesh 41. The first mating tooth 43 is welded to the frame mesh 41 and is arranged in a half circle along the outline of the frame mesh 41. The second mating tooth 44 is welded to the impeller 25 and is arranged in a circle along the outline of the impeller 25. The rotating wheel 45 is rotatably connected to the inner wall of the detection port 22 by a rotating sleeve. The rotating wheel 45 meshes with the first mating tooth 43 and the second mating tooth 44.

[0054] By setting a rotating wheel 45, when the impeller 25 rotates in reverse, it drives the frame mesh 41 to rotate 180 degrees, and guides the water flow in one direction into the detection port 22 through the guide plate 42. When the impeller 25 rotates in the forward direction, it drives the frame mesh 41 to rotate 180 degrees, and guides the water flow in another direction into the detection port 22 through the guide plate 42. In this way, the water flow is divided into two paths, avoiding the backflow of raw water and affecting the water quality analysis results.

[0055] The fixing frame 3 includes a top sleeve 31 set on the top of the housing 1, a first upright 32 set on the top of the top sleeve 31, a first connecting platform 33 set on the outside of the first upright 32, a crossbar 34 passing through the side of the first connecting platform 33, a second connecting platform 35 set on the outside of the crossbar 34, a second upright 36 passing through the bottom of the second connecting platform 35, and a clamping plate 37 set on the bottom of the second upright 36. The outer sides of the first connecting platform 33 and the second connecting platform 35 are provided with a horizontal hole 38 and a vertical hole 39.

[0056] Specifically, the top sleeve 31 is elastically fitted onto the top of the housing 1. The first upright 32 slides in the vertical hole 39 of the first connecting platform 33, the second upright 36 slides in the vertical hole 39 of the second connecting platform 35, and the horizontal bar 34 slides through the horizontal hole 38 of the first connecting platform 33 and the second connecting platform 35. The first upright 32 is fixedly connected to the top sleeve 31. The first upright 32 and the horizontal bar 34 are both fixed to the first connecting platform 33 by bolts. The horizontal bar 34 and the second upright 36 are both fixed to the second connecting platform 35 by friction. The second upright 36 is fixedly connected to the clamping plate 37, which is snapped onto the wall of the seedling pool.

[0057] By setting a fixed frame 3, the horizontal bar 34 can slide within the connecting platform 2 35, which can adjust the distance between the housing 1 and the seedling pond wall. The vertical bar 2 36 can slide within the connecting platform 2 35, which can adjust the depth of the housing 1 inserted into the water surface. This allows for quick adjustment of the detection position, making the equipment more convenient to use and obtaining better detection results.

[0058] The fixing frame 3 also includes a mounting hole 310 inside the connecting platform 35, a pressure strip 311 and a pressure spring 312 disposed inside the mounting hole 310, and a pressure relief hole 313 opened on the outside of the crossbar 34.

[0059] Specifically, the pressure strip 311 is located between the crossbar 34 and the second upright 36. A soft pad is provided at the end of the pressure strip 311 near the second upright 36, and the end of the pressure strip 311 near the crossbar 34 is set as a hemisphere to facilitate entry into the pressure relief hole 313. A ball bearing is provided at the hemisphere end of the pressure strip 311 to reduce the friction when the crossbar 34 slides. The pressure spring 312 is in a compressed state and applies a pushing force to the pressure strip 311 in the direction of the crossbar 34. The pressure relief hole 313 and the pressure strip 311 are located on the same horizontal plane, so that the pressure strip 311 can enter the pressure relief hole 313.

[0060] By setting the pressure bar 311, the pressure bar 311 will apply an additional resistance to the upright rod 36, so that it can better resist the weight of the equipment and keep it in a stable state during testing. At the same time, the resistance generated by the pressure bar 311 will disappear during adjustment. This not only facilitates adjustment, but also avoids serious wear of parts due to excessive friction during adjustment, which would affect the stability and service life of the equipment.

[0061] Example 2, refer to Figures 1-11 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a cleaning component 5 is provided inside the detection port 22. The cleaning component 5 includes an adjustment groove 51 opened in the inner wall of the detection port 22, a screw 52 disposed inside the adjustment groove 51, a sliding sleeve 53 disposed outside the screw 52, ​​a cleaning sleeve 54 disposed outside the two detection rods 24, and a connecting rod 55 disposed between the sliding sleeve 53 and the two cleaning sleeves 54.

[0062] Specifically, the screw 52 is rotatably installed in the adjusting groove 51, which extends upward into the equipment groove 23. The screw 52 extends into the housing 1. The sliding sleeve 53 and the screw 52 are threadedly connected. An adjusting motor that controls the rotation of the screw 52 is installed inside the housing 1. The cleaning sleeve 54 is slidably sleeved on the outside of the detection rod 24. The connecting rod 55 is welded to the cleaning sleeve 54 and threadedly connected to the sliding sleeve 53.

[0063] By setting up the cleaning component 5, when the surface of the detection rod 24 is covered with deposits after the equipment has been used for a period of time, the adjusting motor is started, the screw 52 controls the sliding sleeve 53 to move, and the sliding sleeve 53 controls the cleaning sleeve 54 to slide on the surface of the detection rod 24 to scrape off the deposits. This can reduce detection interference and improve the accuracy of equipment detection.

[0064] The cleaning component 5 also includes a scraping sleeve 56 disposed at the bottom of the cleaning sleeve 54, the lower end of the scraping sleeve 56 being tapered.

[0065] The cleaning component 5 also includes grooves 57 arranged in a linear array on the outside of the cleaning sleeve 56, a pressure ring 58 disposed on the outside of the grooves 57, and an elastic strip 59 disposed on the inside of the pressure ring 58.

[0066] Specifically, the scraping sleeve 56 is threadedly connected to the cleaning sleeve 54, the groove 57 is located at the upper end of the tapered surface at the lower end of the scraping sleeve 56, the pressure ring 58 slides on the outside of the scraping sleeve 56, and the elastic strip 59 is located in one of the grooves 57.

[0067] By setting the cleaning sleeve 56, when the cleaning sleeve 56 slides down, the bottom of the conical surface is forced to close inward, thereby producing a better cleaning effect. When the cleaning sleeve 56 slides up, the scraping force of the cleaning sleeve 56 on the detection rod 24 becomes weaker, which can avoid excessive friction on the detection rod 24 and affect the detection performance. At the same time, by adjusting the position of the elastic strip 59 in the groove 57, the tightness of the conical surface ring below the cleaning sleeve 56 can be controlled.

[0068] Based on embodiments 1-2, the working principle of the seagrass seedling testing water quality detector of the present invention is as follows: The housing 1 is fitted under the top sleeve 31, and the clamping plate 37 is then snapped onto the wall of the seedling pool, so that the crossbar 34 maintains a 90-degree angle with the wall of the seedling pool. Then, holding the connecting platform 1 33 with one hand, push it towards the connecting platform 2 35. The crossbar 34 slides within the connecting platform 2 35. When the pressure relief hole 313 aligns with the mounting hole 310, the pressure spring 312 pushes the pressure strip 311 into the pressure relief hole 313, preventing the pressure strip 311 from... Squeeze the second upright pole 36 again to reduce the resistance it experiences. This allows force to be applied at the first connecting platform 33. The second connecting platform 35 slides up and down on the outside of the second upright pole 36 via the crossbar 34, adjusting the depth of the housing 1 inserted into the water. Then push the first connecting platform 33 away from the second connecting platform 35. The pressure bar 311 is pushed out of the pressure relief hole 313 and pressed against the outside of the second upright pole 36 again, increasing the resistance between the second upright pole 36 and the second connecting platform 35. Continue pushing the first connecting platform 33 to adjust the distance between the housing 1 and the seedling pond wall.

[0069] During testing, the drive motor 26 is started. The drive motor 26 first drives the impeller 25 to rotate in reverse through the drive wheel 27 and the connecting groove 28. The impeller 25 drives the frame mesh 41 to rotate 180 degrees through the rotating wheel 45, so that the guide plate 42 faces one side. The impeller 25 pushes the seedling water to flow from the seedling pool wall to the center of the seedling pool. During this process, the detection rod 24 detects the water quality data. The seedling water flowing out of the detection port 22 is guided by the guide plate 42 to flow obliquely to one side. Then the drive motor 26 starts to drive the impeller 25 to rotate forward. The impeller 25 drives the frame mesh 41 to rotate 180 degrees through the rotating wheel 45, so that the guide plate 42 faces the other side. The guide plate 42 guides the seedling water on the other side to flow to the detection port 22. The detection rod 24 detects the water quality data.

[0070] When deposits accumulate on the surface of the detection rod 24 after the equipment has been used for a period of time, the adjustment motor is started. The adjustment motor drives the screw 52 to rotate. The screw 52 controls the sliding sleeve 53 to move up and down. The sliding sleeve 53 controls the cleaning sleeve 54 to slide up and down on the surface of the detection rod 24 through the connecting rod 55, thus scraping off the deposits on the surface of the detection rod 24.

[0071] The remaining structure is the same as that in Example 1.

[0072] Example 3, referring to Figures 4-8 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the frame mesh 41 is rotatably installed in the detection port 22, and a limit platform is provided between the two, with a reset spring provided on the outside of the limit platform.

[0073] The impeller 25 rotates, driving the rotating wheel 45 to rotate via the mating tooth 44. The rotating wheel 45, through the mating tooth 43, drives the frame mesh 41 to rotate 180 degrees. After the frame mesh 41 rotates 180 degrees, the rotating wheel 45 and the mating tooth 43 no longer mesh. The frame mesh 41 compresses the return spring. When the impeller 25 rotates in the opposite direction, the rotating wheel 45 also rotates in the opposite direction. The return spring pushes the frame mesh 41 so that the mating tooth 43 meshes with the rotating wheel 45 again, thus ensuring the stable operation of the equipment.

[0074] The remaining structure is the same as that in Example 1.

[0075] Example 4, refer to Figures 4-8 This is the fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the diversion component 4 further includes two push blocks 48 disposed on the side of the frame mesh 41 near the impeller 25, two rotating shafts 46 disposed on the top of the rotating wheel 45, and a baffle plate 47 disposed on the outside of the rotating shafts 46.

[0076] Specifically, the rotating shaft 46 is fixedly connected to the rotating wheel 45, and the lever plate 47 is rotatably connected to the rotating shaft 46. The two lever plates 47 are staggered vertically. The lever plate 47 is arc-shaped, and the inner arc side faces the central axis of the rotating wheel 45. The maximum angle of rotation of the lever plate 47 away from the central axis of the rotating wheel 45 does not exceed ninety degrees. A torsion spring is provided between the lever plate 47 and the rotating shaft 46. The two push blocks 48 are located at both ends of the distribution area of ​​the mating teeth 43 and correspond to the two lever plates 47.

[0077] The impeller 25 rotates, driving the rotating wheel 45 to rotate via the mating tooth 44. The rotating wheel 45, through the mating tooth 43, drives the frame mesh 41 to rotate 180 degrees. After the frame mesh 41 rotates 180 degrees, the rotating wheel 45 and the mating tooth 43 no longer mesh. Subsequently, the rotating wheel 45 continues to rotate, no longer driving the frame mesh 41 to rotate. The outer contour of the deflector 47 collides with the push block 48. The deflector 47 deflects towards the center of the rotating wheel 45 to avoid it. When the impeller 25 rotates in the opposite direction, the rotating wheel 45 also rotates in the opposite direction. The inner contour of the deflector 47 contacts the push block 48, pushing the frame mesh 41 to deflect at a certain angle, so that the mating tooth 43 meshes with the rotating wheel 45 again.

[0078] The remaining structure is the same as that in Example 1.
