Description

Technical Field

[0001] The invention relates to the technical field of fishery breeding, in particular to a water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment and an acclimation method thereof. Background Art

[0002] Mandarin fish (Siniperca chuatsi) are a typical warm-water fish, highly sensitive to changes in water temperature. Their optimal growth temperature range is 20°C-30°C, within which they grow rapidly. However, when the water temperature drops below 15°C or rises above 30°C, their growth rate slows significantly. Therefore, controlling water temperature is crucial during the acclimation process.

[0003] In fact, the depth at which mandarin fish move in the pond varies depending on the season and temperature: when the environment is hot and humid, the oxygen content at the bottom of the pond is low. At this time, mandarin fish will move in the upper layer of the pond to obtain oxygen; when the ambient temperature is high, the temperature at the surface of the pond is high. At this time, mandarin fish will move in the lower temperature area at the bottom of the pond. It can be seen that the depth at which mandarin fish move in the water body is affected by the surrounding environment, and its distribution in the pond is very variable. Therefore, to ensure the normal growth of mandarin fish, breeders need to measure the water temperature at different depths in the pond to accurately obtain the specific temperature of the water at each depth in the pond, so as to appropriately regulate the water temperature in the pond.

[0004] At present, when measuring the water temperature in deep water pools, a deep water thermometer is usually used for temperature measurement. This is a thermometer with recording and waterproof functions. When using it, first tie a rope with a depth mark to the end of the deep water thermometer, then put the deep water thermometer into the water, and use the depth mark on the rope to lower the deep water thermometer to the preset height before measuring the temperature; after staying for 1 to 2 minutes, it can be lifted up, and the instrument should be lifted up at a constant speed. After the instrument is raised to the surface, it is necessary to observe and read it as soon as possible; the whole process is complicated to operate, and in the process of lowering the instrument, due to the fluctuation of the water flow in the aquaculture pond, it is very easy to cause the instrument to shake underwater, which makes it impossible for the aquaculture personnel to accurately obtain the water temperature at the preset height; and after the instrument is out of the water, if the operation speed is slow, it is very easy to cause the detection data to disappear, which is not conducive to the aquaculture personnel to control and adjust the temperature of the aquaculture pond. Summary of the Invention

[0005] The purpose of the present invention is to provide a water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment and an acclimation method thereof, so as to solve the problems raised in the above background technology.

[0009] The water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment as described above: the engaging groove includes a spiral groove provided on the driving rod, the spiral grooves are provided in multiple groups at equal intervals, and two adjacent groups of the spiral grooves are connected by a horizontal groove.

[0010] The water temperature detection device for mandarin fish acclimation and breeding with stepped depth adjustment as described above: the triggering member includes a triggering block fixedly arranged on the mounting plate, and the triggering block is provided with a first triggering surface and a second triggering surface.

[0011] The water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment as described above: the suction part includes a piston rod that is sealingly and slidingly arranged in the suction cylinder, and a sliding sleeve is fixedly arranged on one end of the piston rod protruding from the suction cylinder, and a protruding column is formed on the inner wall of the sliding sleeve.

[0013] The water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment as described above: the driving assembly includes a trigger structure and a driving structure, the driving structure is slidably provided on a lifting plate on the mounting plate, a sliding rod is fixedly provided on the lifting plate, a second spring is sleeved on the sliding rod, one end of the second spring abuts against the end of the sliding rod, and the other end abuts against a fixed sleeve slidably provided on the sliding rod, the fixed sleeve is fixedly connected to a guide plate slidably provided on the lifting plate, and the guide plate is also fixedly provided with a tooth plate, and the tooth plate is engaged with a gear coaxially fixedly provided on the rotating rod.

[0014] The water temperature detection device for acclimating and breeding mandarin fish with stepped depth adjustment as described above: the trigger structure includes a plug-in tube fixedly arranged on the storage plate, a first spring is arranged in the plug-in tube, one end of the first spring abuts against the plug-in tube, and the other end abuts against a plug-in rod slidably arranged in the plug-in tube, a wedge block is fixedly arranged on the end of the plug-in rod away from the first spring, a connecting plate is fixedly arranged on the wedge block, a trigger rod is fixedly arranged on the connecting plate, and the trigger rod is slidably arranged in the inclined groove opened on the guide plate.

[0015] A method for acclimating mandarin fish by adjusting the water temperature in a step-by-step depth adjustment manner is also proposed. The device for detecting the water temperature in a step-by-step depth adjustment manner is described above, and comprises the following steps: Step 1: Select a suitable breeding pond, fill it with water to a suitable depth, then add an appropriate amount of mandarin fish fry, use a water temperature detection device to detect the temperature at different depths in the breeding pond, and adjust the water temperature according to the detection results; Step 2: When using the water temperature detection device to detect temperatures at different depths, first fix the positioning plate to the edge of the aquaculture pond weir, then start the lifting component. Then, the lifting component drives the placement plate to descend, and after descending to a certain height, it hovers. During this process, the driving component is triggered by the trigger component, which can drive the suction component to draw water samples at the depth into the temperature measuring cylinder; Step 3: While the storage plate is hovering, the thermometer in the temperature measuring tube comes into contact with the water sample, and the final detected temperature is displayed on the digital display for observation by the aquaculture personnel; Step 4: After the storage plate hovers for a period of time, the lifting assembly drives the storage plate down again, and repeats steps 2 and 3 to detect the water temperature at the next depth.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When using this device, the installation position of the mounting plate can be flexibly selected according to the terrain of the aquaculture pond by bolt fixing, so as to adapt to the deployment requirements of different aquaculture environments; By providing a lifting assembly and utilizing the cooperation between the lifting sleeve and the interlocking groove, the storage plate can be driven to be precisely lowered to a preset height and maintained in a stable state at this height, avoiding the storage plate from shifting due to water flow fluctuations, and ensuring that the temperature measuring cylinder on the storage plate can accurately measure the water temperature at the preset height. At the same time, due to the alternating arrangement of the spiral groove and the horizontal groove, the driving rod can achieve intermittent and step-by-step descent of the storage plate when in operation, thereby completing the temperature collection at different water depths in the aquaculture pond, helping farmers to fully understand the temperature conditions of the aquaculture pond. Furthermore, as the platform descends, the trigger block on the mounting plate cooperates with the drive assembly to drive the suction cylinder on the platform to draw water from a preset height into the temperature measuring cylinder for temperature measurement. Once the water is drawn into the temperature measuring cylinder, the platform hovers, allowing the water in the temperature measuring cylinder to fully contact the temperature measuring portion of the thermometer, ensuring accurate water temperature measurement and more representative temperature data. When the placement plate drops again, the trigger block separates from the drive assembly, the drive assembly resets and drives the suction cylinder to perform reverse movement, draining the water in the temperature measuring cylinder, ensuring the independence of the water samples in the temperature measuring cylinder during continuous testing, so that when the placement plate drops to the next height for temperature measurement, its temperature measurement data will not be affected by the water at the previous height, thereby improving the accuracy of the data collected by the thermometer.

[0020] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0021] See also Figures 1-11 In an embodiment of the present invention, a water temperature detection device for mandarin fish acclimation and breeding with step-by-step depth adjustment includes: A mounting plate 1 that can be detachably mounted on the weir of a breeding pond; Specifically, see Figure 1 、 Figure 2 、 Figure 3 A positioning plate 101 is fixedly provided on the above-mentioned mounting plate 1, and screw holes are provided on the positioning plate 101. After the site selection of the breeding pond is completed, a suitable location is selected, and the mounting plate 1 is placed in the breeding pond. Then, the positioning plate 101 is fixed to the edge of the pond weir with bolts. Subsequently, the cooperation between the various components provided on the mounting plate 1 can be used to detect the temperature of water bodies at different depths in the breeding pond, so that the breeding personnel can monitor the water temperature in the breeding pond. According to the detection results, the breeding personnel can adjust the temperature, thereby facilitating the breeding and domestication of the mandarin fish by the breeding personnel.

[0022] The mounting plate 1 is provided with a lifting assembly, which can drive the lifting member provided on the mounting plate 1 to intermittently descend in the longitudinal direction; The lifting member includes a storage plate 4, a sleeve 9 and a lifting sleeve 10 are fixedly provided on the side of the storage plate 4 facing the mounting plate 1, the sleeve 9 is slidably connected to the guide rod 3 fixedly provided on the mounting plate 1, and the lifting sleeve 10 is connected to the lifting assembly; The lifting assembly includes a driving rod 2 rotatably mounted on the mounting plate 1, an engaging groove formed on the outer wall of the driving rod 2, a protrusion 1001 formed on the inner wall of the lifting sleeve 10 slidingly disposed in the engaging groove, and the engaging groove and the protrusion 1001 cooperate to drive the storage plate 4 to intermittently lift and lower; For details, see Figure 1 、 Figure 2 、 Figure 4 The above-mentioned driving rod 2 is coaxially fixed with the output shaft of the servo motor fixed on the mounting plate 1, and with the cooperation of the sleeve tube 9 and the guide rod 3 and the lifting sleeve 10 and the driving rod 2, the storage plate 4 can only slide along the longitudinal direction of the mounting plate 1; therefore, after starting the servo motor, the driving rod 2 driven to rotate by the servo motor can drive the lifting sleeve 10 and the storage plate 4 to move intermittently under the cooperation of the engaging groove and the protrusion 1001, and in the process of the storage plate 4 descending to a certain height to stop, the trigger part on the mounting plate 1 cooperates with the driving assembly on the storage plate 4, so that the temperature measuring tube 5 set on the storage plate 4 can measure the temperature of the water body at that depth only when it descends to the current position, thereby improving the accuracy of the detection.

[0023] Specifically, see Figure 1 、 Figure 2 、 Figure 3 The engaging groove includes a spiral groove 201 provided on the driving rod 2, and the spiral groove 201 is provided in multiple groups at equal intervals, and two adjacent groups of the spiral grooves 201 are connected by a horizontal groove 202; Preferably, three groups of the spiral grooves 201 are equidistantly arranged, and the end of the spiral groove 201 at the bottom is connected to a horizontal groove 202 .

[0024] In the initial state, the above-mentioned storage plate 4 is close to the servo motor. At this time, the protrusion 1001 is located at the end of the stroke of the uppermost spiral groove 201. When it is necessary to measure the temperature of water bodies at different depths, the servo motor is started, and then the driving rod 2 is continuously rotated clockwise (refer to Figure 1 Description), during the rotation, the squeezing of the spiral groove 201 on the protrusion 1001 can force the lifting sleeve 10 to drive the storage plate 4 to descend until the protrusion 1001 is engaged with the horizontal groove 202, and the storage plate 4 stops after descending to a certain height; with the continued rotation of the driving rod 2, the protrusion 1001 slides in the horizontal groove 202, and the storage plate 4 maintains its current height position unchanged, so that the temperature measuring tube 5 on the storage plate 4 can measure the temperature of the water at this height; until the protrusion 1001 moves to the end of the stroke of the horizontal groove 202 and engages with the next spiral groove 201, the driving rod 2 that continues to rotate will drive the storage plate 4 to descend for the second time with the cooperation of the next set of spiral grooves 201; the above process is repeated in this way, and the temperature of different water levels in the aquaculture pond can be detected, so that the aquaculture personnel can control the overall temperature of the aquaculture pond.

[0025] The mounting plate 1 is also provided with multiple groups of triggering members at equal intervals; The trigger member includes a trigger block 8 fixedly disposed on the mounting plate 1 , and the trigger block 8 is provided with a first trigger surface 801 and a second trigger surface 802 ; Preferably, see Figure 1 、 Figure 2 、 Figure 3 The trigger blocks 8 are arranged in three groups at equal intervals. Each group of the trigger blocks 8 is arranged in an "isosceles trapezoidal structure", including a shorter upper base, a longer lower base and two groups of inclined waist surfaces. The two groups of inclined waist surfaces are set as a first trigger surface 801 and a second trigger surface 802. During the descending process of the placement plate 4, the first trigger surface 801 first contacts the driving component on the placement plate 4, triggering the driving component to operate, so that the temperature measuring tube 5 contacts the water body, thereby performing temperature measurement; when the placement plate 4 is subsequently lowered again, the second trigger surface 802 cooperates with the driving component to enable the temperature measuring tube 5 to contact the current water body, thereby facilitating the temperature measuring tube 5 to contact the water body at the next depth for temperature measurement.

[0026] A temperature measuring cylinder 5 is fixedly provided on the lifting member, and the temperature measuring cylinder 5 is communicated with a water sample extraction assembly provided on the lifting member. The water sample extraction assembly includes a suction cylinder 6 fixedly provided on the lifting member and communicated with the temperature measuring cylinder 5. A suction member is sealingly and slidably provided inside the suction cylinder 6. The suction member cooperates with a driving assembly provided on the lifting member. When the lifting member descends to a certain height, the driving assembly is triggered by the trigger member at the corresponding height, and can drive the suction member to draw the water sample into the temperature measuring cylinder 5; For details, see Figure 7 A placement cavity is provided on the side of the temperature measuring tube 5 close to the placement plate 4, and a thermometer 18 is fixedly provided in the placement cavity. The temperature measuring part and the digital display part of the thermometer 18 are isolated by an isolation ring 502. The outer wall of the isolation ring 502 is provided with a circle of rubber ring. The rubber ring can ensure that the isolation ring 502 fits tightly with the inside of the placement cavity, so that when the subsequent water sample extraction component is activated and the water is pumped into the temperature measuring tube 5, no water will enter the placement cavity, thereby ensuring that the thermometer 18 only contacts the water sample at the height to be detected, thereby improving the temperature measurement accuracy of the thermometer 18.

[0027] When the lifting member moves downward again, the driving assembly separates from the trigger member and quickly resets, which can drive the suction member to move in the reverse direction to discharge the sample drawn into the temperature measuring cylinder 5; Specifically, see Figure 8 The suction member includes a piston rod 21 that is sealingly and slidingly arranged in the suction cylinder 6. A sliding sleeve 11 is fixedly arranged on one end of the piston rod 21 that protrudes from the suction cylinder 6. A protruding column 1101 is formed on the inner wall of the sliding sleeve 11. The water sample extraction assembly further includes a rotating rod 12 rotatably mounted on the storage plate 4 , the sliding sleeve 11 is sleeved on the rotating rod 12 , and the protruding post 1101 is slidably disposed in a rotating groove 1201 provided on the outer wall of the rotating rod 12 ; Combine Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 The end of the rotating rod 12 away from the storage plate 4 is rotatably connected to the lifting plate 7 slidably arranged on the mounting plate 1.

[0028] In the initial state, the sliding sleeve 11 is close to the storage plate 4. At this time, the protruding post 1101 is located at the beginning of the travel of the rotating groove 1201. When the lifting assembly drives the storage plate 4 to descend to a height close to the specified height, the driving assembly cooperates with the trigger block 8 at the current specified height to drive the rotating rod 12 to rotate clockwise (combined with the Figure 1 、 Figure 61 and 1 , and the water level is increased, so that the water level is increased, and the water level is increased, so that the water level is increased. When the water level is increased, the water level increases, and the water level increases. When the water level is increased, the water level increases, and the water level increases. When the water level is increased, the water level increases, and the water level increases. When the water level is increased, the water level increases, and the water level increases. When the water level is increased, the water level increases, and the water level increases. When the water level is increased, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases. When the water level increases, the water level increases, and the water level increases.

[0029] When the subsequent placement plate 4 moves down again, the driving assembly and the trigger block 8 are separated and reset, which can drive the rotating rod 12 to reverse, so that the piston rod 21 moves back to the initial position toward the placement plate 4, and the water sample in the temperature measuring cylinder 5 is discharged, so that when the placement plate 4 descends to the next water level to be measured, the thermometer 18 only contacts the water at the next water level for temperature measurement.

[0030] Specifically, see Figure 6 、 Figure 9 、 Figure 10 、 Figure 11 , the driving assembly includes a trigger structure and a driving structure, the driving structure is slidably provided on the lifting plate 7 on the mounting plate 1, the lifting plate 7 is fixedly provided with a slide rod 22, the slide rod 22 is sleeved with a second spring 24, one end of the second spring 24 abuts against the end of the slide rod 22, and the other end abuts against a fixed sleeve 25 slidably provided on the slide rod 22, the fixed sleeve 25 is fixedly connected to the guide plate 15 slidably provided on the lifting plate 7, and the guide plate 15 is further fixedly provided with a toothed plate 14, the toothed plate 14 is meshed with a gear 13 coaxially fixedly provided on the rotating rod 12; In particular, a T-block 701 is fixedly provided on the side of the lifting plate 7 away from the storage plate 4. The T-block 701 is slidably set in the T-slot 103 opened on the mounting plate 1. With the cooperation of the T-block 701 and the T-slot 103, the lifting plate 7 can only slide along the longitudinal direction of the mounting plate 1.

[0031] Specifically, a clamping block 1502 is fixedly provided on the above-mentioned guide plate 15, and the clamping block 1502 is slidably set in the clamping groove 702 opened on the lifting plate 7. Under the cooperation between the clamping block 1502 and the clamping groove 702, the guide plate 15 can only slide along the width direction of the lifting plate 7.

[0032] In particular, the above-mentioned second spring 24 is always in a compressed state, pushing the guide plate 15 to have a tendency to move closer to the positioning plate 101; during the descending process of the storage plate 4, the trigger block 8 cooperates with the trigger structure to force the guide plate 15 to drive the tooth plate 14 to descend. During this process, the second spring 24 is further squeezed, and the tooth plate 14 drives the gear 13 to drive the rotating rod 12 to rotate clockwise, so that the piston rod 21 performs a suction operation to draw water into the temperature measuring cylinder 5 for temperature detection; after the trigger block 8 is separated from the trigger structure, the second spring 24 releases its elastic potential energy, which can push the guide plate 15 to drive the tooth plate 14 to reset, so that the piston rod 21 returns to its initial position and the water in the temperature measuring cylinder 5 is drained.

[0033] For details, see Figure 10 , the trigger structure includes a plug-in tube 16 fixedly arranged on the storage plate 4, a limit block 1601 is fixedly provided on the plug-in tube 16, and the limit block 1601 is slidably arranged in the limit groove 104 opened on the mounting plate 1. Under the cooperation of the limit groove 104 and the limit block 1601, the plug-in tube 16 can always maintain a horizontal state and descend. A first spring 23 is provided in the plug-in tube 16, one end of the first spring 23 abuts against the plug-in tube 16, and the other end abuts against the plug-in rod 19 slidably arranged in the plug-in tube 16, and the plug-in rod 19 is fixedly provided with a wedge block 17 at one end away from the first spring 23, and a connecting plate 20 is fixedly provided on the wedge block 17, and a trigger rod 2001 is fixedly provided on the connecting plate 20, and the trigger rod 2001 is slidably provided in the oblique groove 1501 opened on the guide plate 15; In particular, the wedge block 17 is configured as an "isosceles trapezoidal structure", including a shorter upper base, a longer lower base and two sets of inclined waist surfaces, and the two sets of inclined waist surfaces are respectively provided with a first inclined surface 1701 and a second inclined surface 1702.

[0034] The first spring 23 is always in a compressed state, pushing the plug-in rod 19 to move toward the outside of the plug-in tube 16. It should be noted that the elastic potential energy stored in the second spring 24 is greater than that of the first spring 23. Therefore, in the initial state, the trigger rod 2001 is located at the end of the stroke of the inclined slot 1501 away from the end of the fixed sleeve 25; when the storage plate 4 is lowered to the specified height by the lifting assembly, the first inclined surface 1701 of the wedge block 17 contacts the first trigger surface 801 of the trigger block 8. As the storage plate 4 continues to descend, the trigger block 8 forces the wedge block 17 to retract toward the inside of the plug-in tube 16. At this time, the trigger rod 2001 cooperates with the inclined slot 1501 to drive the guide plate 15 to drive the tooth plate 14 to descend; until the upper bottom surface of the wedge block 17 contacts the upper bottom surface of the trigger block 8, the storage plate 4 is lowered to the specified height. The trigger rod 2001 moves to the end of the stroke of the inclined groove 1501; during this process, the descending guide plate 15 drives the rotating rod 12 to rotate in cooperation with the tooth plate 14 and the gear 13, and then drives the piston rod 21 to draw the external water into the temperature measuring cylinder 5; during the subsequent suspension of the storage plate 4, the temperature measuring part of the thermometer 18 is in full contact with the water, which can accurately measure the temperature of the water under the current water level and feed back the final temperature measurement data to the digital display screen 102.

[0035] As the storage plate 4 continues to descend, the upper bottom surface of the wedge block 17 gradually separates from the upper bottom surface of the trigger block 8, and then the second inclined surface 1702 of the wedge block 17 contacts the second trigger surface 802 of the trigger block 8. As the storage plate 4 continues to descend, the wedge block 17 is gradually reset under the push of the first spring 23; during this process, the trigger rod 2001 cooperates with the inclined groove 1501 to drive the guide plate 15 to rise, so that the rotating rod 12 is reversed, and the water in the temperature measuring tube 5 is drained, so that when the storage plate 4 descends to the next specified height, the temperature measuring tube 5 can measure the temperature of the water at the next specified height again.

[0036] A method for acclimating mandarin fish by adjusting the water temperature in a step-by-step depth adjustment manner is also proposed. The device for detecting the water temperature in a step-by-step depth adjustment manner is described above, and comprises the following steps: Step 1: Select a suitable breeding pond, fill it with water to a suitable depth, then add an appropriate amount of mandarin fish fry, use a water temperature detection device to detect the temperature at different depths in the breeding pond, and adjust the water temperature according to the detection results; Step 2: When using the water temperature detection device to detect temperatures at different depths, first fix the positioning plate 101 to the edge of the aquaculture pond weir, then start the lifting component, which then drives the placement plate 4 to descend, and after descending to a certain height, it hovers. During this process, the driving component is triggered by the trigger component, which can drive the suction component to draw water samples at the depth into the temperature measuring cylinder 5; Step 3: While the storage plate 4 is suspended, the thermometer 18 in the temperature measuring tube 5 comes into contact with the water sample, and the final detected temperature is displayed on the digital display screen 102 for observation by the aquaculture personnel; Step 4: After the storage plate 4 hovers for a period of time, the lifting assembly drives the storage plate 4 down again, and repeats steps 2 and 3 to detect the water temperature at the next depth.
