Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of monitoring technology, and more specifically, to an online monitoring device for water quality in fish fry cultivation. Background Technology

[0002] An online water quality monitoring device for fish fry rearing is typically used to ensure that the water quality of the growing environment for fish fry is at its most suitable level during the rearing process. This device helps fish farmers identify and address water quality issues promptly by monitoring various water quality parameters in real time, such as temperature, pH, dissolved oxygen, ammonia nitrogen, nitrite, and turbidity.

[0003] According to a public disclosure (Publication No.: CN 215641215 U), an online monitoring device for water quality in fish fry cultivation includes a mounting plate. Vertical plates are fixedly connected to both sides of the top of the mounting plate. A horizontal plate is fixedly connected to the top of the vertical plates. A first motor is fixedly connected to the top of the horizontal plate. The shaft of the first motor passes through the horizontal plate and is fixedly connected to a lead screw. This disclosure has the advantages of efficient protection of the sensor surface and convenient observation of the fish fry growth environment.

[0004] In the aforementioned application, the cooperation between components such as vertical plates and lead screws makes it difficult to solve the problem of not being able to protect the control box and sensors and to avoid equipment damage. This results in severe weather (such as heavy rain and strong winds) affecting the monitoring system, making it impossible to carry out monitoring work without interruption, which needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an online monitoring device for water quality in fish fry cultivation, which solves the technical problem in related technologies / prior technologies that an online monitoring device for water quality in fish fry cultivation cannot protect the control box and sensors and cannot avoid equipment damage.

[0006] According to one aspect, at least one embodiment of this disclosure provides an online monitoring device for water quality in fish fry cultivation, comprising a base plate, a support rod fixedly connected to the top of the base plate, a monitoring and protection assembly disposed on the side of the support rod, the monitoring and protection assembly including a control box, the side of the control box fixedly connected to the side of the support rod, a sensor disposed on the inner wall of the control box, an output line passing through the side of the sensor, a dissolved oxygen sensor disposed at the end of the output line away from the sensor, a support rod fixedly connected to the side of the support rod, a cylindrical rod fixedly connected to the side of the support rod, a rotating rod rotatably connected to the side of the cylindrical rod, a protective cover fixedly connected to the circumference of the rotating rod, a gear fixedly connected to the end of the rotating rod away from the cylindrical rod, a support plate fixedly connected to the top of the support rod, a rack slidably connected to the top of the support plate, an L-shaped rod fixedly connected to the side of the support plate, an electric telescopic rod fixedly connected to the side of the L-shaped rod, and an electric telescopic rod fixedly connected to the side of the electric telescopic rod away from the L-shaped rod, the end of the electric telescopic rod away from the L-shaped rod fixedly connected to the side of the rack.

[0007] For example, in at least one embodiment of the present disclosure, an online monitoring device for water quality in fish fry cultivation is provided, which further includes: a switch provided at the top of the electric telescopic rod, the rack and gear meshing with each other, and the control box located on the displacement trajectory of the protective cover. This is beneficial because the rack will move when the gear moves.

[0008] A rectangular rod is fixedly connected to the side of the support plate. A groove is provided at the top of the rectangular rod. A short rod is slidably connected to the inner wall of the groove. The end of the short rod away from the groove is fixedly connected to the side of the rack. The design of the short rod helps to limit the movement trajectory of the rack and prevent the movement trajectory of the rack from deviating.

[0009] The sensor has a button on its side, and the control box has a cover plate that is rotatably connected to its side. The button design makes it convenient to control and adjust the sensor.

[0010] The support rod is located on the side of the output line, and a warning sign is provided on the side of the cover plate. The support rod is used to support the output line and prevent it from dragging on the ground.

[0011] According to another aspect, at least one embodiment of this disclosure also provides an online monitoring device for water quality in fish fry cultivation, further comprising: a component for preventing poor contact on the side of the control box, the component including a squeezing rod, one end of the squeezing rod being fixedly connected to the circumferential surface of a rotating rod, a vertical rod being fixedly connected to the circumferential surface of the cylindrical rod, a rectangular groove being formed on the side of the vertical rod, a sliding block being slidably connected to the inner wall of the rectangular groove, a connecting plate being fixedly connected to the side of the sliding block, an extension plate being fixedly connected to the side of the connecting plate, and an arc-shaped cover plate being fixedly connected to the bottom of the connecting plate, the arc-shaped cover plate covering the connection between the output line and the control box, reducing the possibility of poor contact caused by line damage.

[0012] For example, in at least one embodiment of the present disclosure, a water quality online monitoring device for fish seedling cultivation is provided, which further includes: the output line is located on the displacement trajectory of the arc-shaped cover plate, and the extension plate is located on the displacement trajectory of the extrusion rod. This design is beneficial to extruding the extension plate downward when the extrusion rod moves.

[0013] A spring is fixedly connected to the inner wall of the rectangular groove. The end of the spring away from the rectangular groove is fixedly connected to the bottom of the sliding block. The design of the spring is conducive to the automatic reset of the sliding block, connecting plate, and extension plate when the sliding block is not subjected to compression displacement.

[0014] A limiting rod is fixedly connected to the inner wall of the rectangular groove. The end of the limiting rod away from the rectangular groove passes through the bottom of the sliding block. The design of the limiting rod helps to limit the sliding block and prevent the displacement trajectory of the sliding block from deviating.

[0015] The arc-shaped cover is located at the top of the output line, and the dissolved oxygen sensor is located below the control box. This design helps to cover the output line when the arc-shaped cover moves downward.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. This disclosure utilizes the coordination between components such as the internal control box, sensors, output lines, and dissolved oxygen sensors of the monitoring and protection assembly to automatically move the protective cover onto the control box when the equipment is not in use. This reduces the need for human intervention. This automated design improves the convenience and operability of the equipment, allowing aquaculture personnel to manage the monitoring system more easily, protect the control box and sensors, and avoid environmental pollution caused by equipment damage. Severe weather (such as heavy rain and strong winds) will not directly affect the monitoring system, enabling uninterrupted monitoring and thus providing continuous protection for the environment.

[0018] 2. In this disclosure, through the cooperation of components such as the extrusion rod, rectangular groove, sliding block, and arc-shaped cover plate inside the anti-poor contact component, the device achieves the effect of the extrusion rod rotating counterclockwise to squeeze the extension plate and drive the arc-shaped cover plate to move downward, thereby covering and protecting the connection between the output line and the control box. This design can effectively prevent problems such as loosening, cracking or poor contact at the connection between the output line and the control box due to external interference or long-term use, ensuring the long-term stable operation of the equipment.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5As shown, this invention illustrates an online monitoring device for water quality in fish fry rearing according to an embodiment of the present disclosure. The device includes a base plate 1, a support rod 2 fixedly connected to the top of the base plate 1, a monitoring and protection assembly 3 on the side of the support rod 2, a control box 31 fixedly connected to the side of the support rod 2, a sensor 32 on the inner wall of the control box 31, an output line 33 passing through the side of the sensor 32, a dissolved oxygen sensor 35 at the end of the output line 33 furthest from the sensor 32, and a support rod 34 fixedly connected to the side of the support rod 2. A cylindrical rod 36 is fixedly connected to the side of the support rod 2. A rotating rod 37 is rotatably connected to the side of the cylindrical rod 36. A protective cover 38 is fixedly connected to the circumference of the rotating rod 37. A gear 39 is fixedly connected to the end of the rotating rod 37 away from the cylindrical rod 36. A support plate 310 is fixedly connected to the top of the support rod 2. A rack 311 is slidably connected to the top of the support plate 310. An L-shaped rod 312 is fixedly connected to the side of the support plate 310. An electric telescopic rod 313 is fixedly connected to the side of the L-shaped rod 312. The end of the electric telescopic rod 313 away from the L-shaped rod 312 is fixedly connected to the side of the rack 311.

[0033] In some examples, a switch 314 is provided on the top of the electric telescopic rod 313, the rack 311 and the gear 39 mesh with each other, and the control box 31 is located on the displacement trajectory of the protective cover 38. This is advantageous because the rack 311 will move when the gear 39 moves.

[0034] A rectangular rod 315 is fixedly connected to the side of the support plate 310. A groove 316 is provided on the top of the rectangular rod 315. A short rod 317 is slidably connected to the inner wall of the groove 316. The end of the short rod 317 away from the groove 316 is fixedly connected to the side of the rack 311. The design of the short rod 317 helps to limit the movement trajectory of the rack 311 and prevent the movement trajectory of the rack 311 from deviating.

[0035] A button 5 is provided on the side of the sensor 32, and a cover plate 6 is rotatably connected to the side of the control box 31. The button 5 is designed to facilitate the control and adjustment of the sensor 32.

[0036] The support rod 34 is located on the side of the output line 33, and a warning sign is provided on the side of the cover plate 6. The support rod 34 is used to support the output line 33 to prevent the output line 33 from dragging on the ground.

[0037] For example, such as Figures 1-5As shown, an output line 33 runs through the side of sensor 32, and the other end of the output line 33 is connected to dissolved oxygen sensor 35, thus connecting dissolved oxygen sensor 35 and sensor 32. Sensor 32 controls dissolved oxygen sensor 35. Dissolved oxygen sensor 35 is then placed in water to monitor the dissolved oxygen concentration in real time. Through this data, aquaculture personnel can ensure that the dissolved oxygen concentration in the water is within the optimal range required for the growth of fish fry. To prevent impact damage to control box 31 and sensor 32 under severe weather conditions, when not in use, pressing switch 314 activates electric telescopic rod 313. The telescopic rod of electric telescopic rod 313 retracts towards the side closer to L-shaped rod 312, pushing rack 311 to slide on top of support plate 310. The sliding of rack 311 causes gear 39 to rotate counterclockwise, which in turn causes rotating rod 37 to rotate counterclockwise. The counterclockwise rotation of rotating rod 37 causes protective cover 38 to rotate counterclockwise, and the counterclockwise rotation of protective cover 38 moves towards the side closer to the support plate 310. One side of the control box 31 rotates towards the top of the control box 31, covering it from top to bottom and protecting the control box 31 and the sensor 32 inside. The dissolved oxygen sensor 35 monitors the dissolved oxygen concentration in the water in real time, allowing aquaculture personnel to understand the water quality and ensure that the oxygen concentration in the water is within the optimal range for fish fry growth. This helps prevent oxygen deficiency and ensures healthy fish growth. When the equipment is not in use, pressing the switch 314 activates the electric telescopic rod 313, automatically moving the protective cover 38 onto the control box 31, reducing the need for human intervention. This automated design improves the convenience and operability of the equipment, allowing aquaculture personnel to manage the monitoring system more easily, protecting the control box 31 and sensor 32, and avoiding environmental pollution caused by equipment damage. Severe weather (such as heavy rain and strong winds) will not directly affect the monitoring system, allowing monitoring to continue uninterrupted, thus providing continuous protection for the environment.

[0038] like Figures 1-5 As shown, this invention illustrates an online monitoring device for water quality in fish fry cultivation according to another embodiment of the present disclosure. A poor contact prevention component 4 is provided on the side of the control box 31. The poor contact prevention component 4 includes a pressing rod 41, one end of which is fixedly connected to the circumferential surface of a rotating rod 37. A vertical rod 42 is fixedly connected to the circumferential surface of a cylindrical rod 36. A rectangular groove 43 is provided on the side of the vertical rod 42. A sliding block 44 is slidably connected to the inner wall of the rectangular groove 43. A connecting plate 45 is fixedly connected to the side of the sliding block 44. An extension plate 46 is fixedly connected to the side of the connecting plate 45. An arc-shaped cover plate 47 is fixedly connected to the bottom of the connecting plate 45. The arc-shaped cover plate 47 covers the connection point between the output line 33 and the control box 31, reducing the possibility of poor contact caused by line damage.

[0039] In some examples, the output line 33 is located on the displacement trajectory of the arc-shaped cover plate 47, and the extension plate 46 is located on the displacement trajectory of the extrusion rod 41. This design is advantageous because when the extrusion rod 41 moves, the extension plate 46 is extruded downwards.

[0040] A spring 48 is fixedly connected to the inner wall of the rectangular groove 43. The end of the spring 48 away from the rectangular groove 43 is fixedly connected to the bottom of the sliding block 44. The design of the spring 48 is conducive to the automatic reset of the sliding block 44, the connecting plate 45, and the extension plate 46 when the sliding block 44 is not subjected to compression displacement.

[0041] A limiting rod 49 is fixedly connected to the inner wall of the rectangular groove 43. The end of the limiting rod 49 away from the rectangular groove 43 passes through the bottom of the sliding block 44. The design of the limiting rod 49 is conducive to limiting the sliding block 44 and preventing the displacement trajectory of the sliding block 44 from deviating.

[0042] The arc-shaped cover 47 is located at the top of the output line 33, and the dissolved oxygen sensor 35 is located below the control box 31. This design is beneficial to cover the output line 33 when the arc-shaped cover 47 moves downward.

[0043] For example, such as Figures 1-5 As shown, by rotating the aforementioned central lever 37 counterclockwise, the lever 37 will drive the pressing lever 41 to rotate counterclockwise, causing the pressing lever 41 to move closer to the base plate 1. The extension plate 46 is located on the movement trajectory of the pressing lever 41. When the pressing lever 41 rotates counterclockwise, it will press against the extension plate 46, causing the extension plate 46 to move downwards. The downward movement of the extension plate 46 will drive the sliding block 44 to move downwards along the rectangular groove 43, causing the arc-shaped cover plate 47 to move downwards. The connection between the output line 33 and the control box 31 is located on the movement trajectory of the arc-shaped cover plate 47. When the arc-shaped cover plate 47 moves downwards, it will cover the connection between the output line 33 and the control box 31 for protection, reducing the possibility of loosening or cracking at the connection between the output line 33 and the control box 31. Poor contact caused by cracks can affect online water quality monitoring. The device uses a counterclockwise rotating squeezing rod 41 to squeeze the extension plate 46 and move the arc-shaped cover plate 47 downward, thereby covering and protecting the connection between the output line 33 and the control box 31. This design can effectively prevent problems such as loosening, cracking or poor contact between the output line 33 and the control box 31 due to external interference or long-term use, ensuring long-term stable operation of the equipment. Stable electrical connection helps prevent the water quality monitoring system from being interrupted due to poor contact, thereby ensuring real-time monitoring of water quality during the fish fry cultivation process. Water quality is the most critical factor in fish farming. Any monitoring interruption will make it difficult to detect water quality problems in time, thus affecting the healthy growth of fish.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
