[0031] Figure 1 This is a schematic diagram of the structure of an oyster infrared heart rate measuring device provided in an embodiment of the present invention, with reference to... Figure 1This invention provides an oyster infrared heart rate measuring device, including a test basin, a mounting rod, a base, a movable arm, a fixed arm, a drilling assembly, a spray pipe, a clamping assembly, a seawater supply assembly, an infrared sensor, and a signal processing assembly. The mounting rod and test basin are both located on the base. The movable arm and fixed arm are both connected to the mounting rod via a rotating shaft. The drilling assembly and spray pipe are both mounted on the movable arm. The seawater supply assembly is connected to the spray pipe. The clamping assembly is mounted on the fixed arm. The infrared probe of the infrared sensor is detachably connected to the clamping assembly. The signal processing assembly is electrically connected to the infrared sensor. The seawater supply assembly is connected to the spray pipe. The drilling assembly is used to drill a hole in the shell of the oyster's heart region. The spray pipe is used to spray seawater onto the oyster shell during the drilling process. The seawater supply assembly is used to supply seawater to the spray pipe. The clamping assembly is used to keep the infrared probe in contact with the oyster's heart. The infrared sensor is used to collect the infrared sensing signal from the oyster's heart. The signal processing assembly is used to analyze and process the infrared sensing signal to obtain the oyster heart rate measurement result.

[0032] Specifically, in this embodiment, the oyster infrared heart rate measuring device can be as follows: Figure 1 As shown, the system includes an infrared sensor 100, a signal processing module 200 electrically connected to the infrared sensor 100, a seawater supply assembly 300, a tool rack 400, a test basin 500 for holding oysters, a drilling assembly 600, and a spray pipe 700. The tool rack 400 includes a base 410, a mounting rod 420 mounted on the base 410, a movable arm 430 and a fixed arm 440 respectively rotatably connected to the mounting rod 420 along a vertical axis; one end of the fixed arm 440 is provided with a clamping assembly (…). Figure 1 (Not shown in the image), the end of the clamping assembly is detachably connected to the infrared probe of the infrared sensor 100; the moving arm 430 and the fixed arm 440 are located above the test basin 500; the drilling assembly 600 and the spray pipe 700 are installed at the end of the moving arm 430, the nozzle of the spray pipe 700 faces the drill bit of the drilling assembly 600, the inlet of the spray pipe 700 is connected to the outlet of the seawater supply assembly 300, and the signal processing module 200 is electrically connected to the infrared sensor.

[0033] The procedure for operating this device to monitor the heart rate of oysters is as follows: Place the oyster into the test basin 500, rotate the movable arm 430 above the test basin 500, press down on the oyster with one hand, and operate the movable arm 430 with the other hand to move the drilling component 600 downwards to the heart position of the oyster. Activate the seawater supply component 300 and the drilling component 600, and the drill bit will drill a hole in the shell. Simultaneously, the spray pipe 700 will spray seawater. The low temperature of the seawater helps to cool the oyster and prevents the drill bit from damaging soft tissues. Since both the drilling component 600 and the spray pipe 700 are fixed to the movable arm 430, drilling and seawater spraying can be achieved by operating the movable arm 430 with one hand, allowing one person to complete the oyster drilling. After drilling is completed, turn off the seawater supply component 300 and the drilling component 600, and reset the movable arm 430. Then, rotate the fixing arm 440 so that it is positioned above the test basin 500, securing the infrared probe and ensuring it is in contact with the oyster's heart. Finally, pour seawater suitable for oyster survival into the test basin 500 and begin the test. Seawater can also be supplied through the seawater supply component 300.

[0034] For example, the composition of the seawater supply component 300 may be as follows: Figure 3 As shown, the system includes a tank 310 containing seawater and a second pump 320 connected to the outlet of the tank 310; the second pump 320 outputs the seawater from the tank 310 to the spray pipe 700. The seawater in the tank 310 may be cooled before being added to the tank 310 for immediate use.

[0035] It can be recognized that the beneficial effects of the present invention include: by integrating the drilling component and the spray pipe onto the same mobile arm, a single person can complete the drilling of oyster shells and the cooling operation via spraying, simplifying the operation steps for measuring the heart rate of oysters and saving manpower; by fixing the infrared sensor to the drilled hole in the oyster shell with the fixing component, the infrared sensor can directly contact the oyster's heart without the need for chemical adhesives, reducing the possibility of stress response in the oyster and facilitating long-term continuous monitoring of oyster heart rate; by analyzing the infrared sensor signal to achieve heart rate measurement, no destructive damage to the oyster is required, and compared with traditional monitoring methods, it has higher monitoring accuracy, providing a more accurate data basis for scientific aquaculture and efficient transportation.

[0036] In some alternative embodiments, the movable arm is a multi-axis articulated arm, with a fixing plate installed at the joint end of the movable arm, and the punching assembly and spray pipe are both installed on the fixing plate.

[0037] Specifically, refer to Figure 2In this embodiment, the movable arm 430 is a multi-axis articulated arm, including a first joint 431, a second joint 432 and an end joint 433 that are rotatably connected in sequence. The first joint 431 is rotatably connected to the mounting rod 420. The end joint 433 is equipped with a fixing plate 434, and the drilling assembly 600 and the spray pipe 700 are both installed on the fixing plate 434.

[0038] By manipulating the end joint 433, the drilling assembly 600 and the spray pipe 700 can be suspended above the test basin. Then, by rotating the first joint 431 relative to the mounting rod 420, the drilling assembly 600 can be aligned with the oyster's heart. The rotation points of the first joint 431, second joint 432, and end joint 433 of the multi-axis articulated arm can be achieved through a damping structure; the specific implementation is not limited in this embodiment. Since the oyster's shell is not very hard, the drilling assembly 600 only needs to be a small drilling tool; therefore, existing multi-axis articulated arms with hovering functionality can meet the requirements. Alternatively, a locking mechanism can be used to fix the moving arm.

[0039] For example, refer to Figure 2 In this embodiment, fixing plate handles 435 can also be provided on both sides of the fixing plate 434. The handles 435 facilitate the user's operation of the moving arm 430. By pushing and pulling the handles, the multi-axis articulated arm is moved, in which the drilling assembly 600 and the spray pipe 700 can move in the Z and Y axes, while the first joint 431 can rotate relative to the mounting rod 420, allowing the drilling assembly 600 and the spray pipe 700 to move in the X axis, realizing the three-dimensional movement of the drilling assembly 600 and the spray pipe 700, so that the drill bit of the drilling assembly 600 can be aligned with the heart of the oyster.

[0040] In some alternative embodiments, the spray pipe is connected to the outlet of the seawater supply assembly via a telescopic pipe.

[0041] Specifically, in this example, the spray pipe 700 is connected to the outlet end of the seawater supply assembly 300 via a telescopic tube. The telescopic tube can extend or shorten as the spray pipe 700 moves, adapting to changes in the position of the spray pipe 700, and maintaining connection with the seawater supply assembly 300 even if the position of the spray pipe 700 changes. The seawater supply assembly 300 can be any existing laboratory device, and the present invention does not impose specific limitations on it.

[0042] In some alternative embodiments, the clamping assembly includes a moving rod and a clamping member, the clamping member being mounted at the end of the moving rod and detachably connected to the infrared detector.

[0043] In some alternative embodiments, the fixed arm is a telescopic structure with a through groove and a locking hole. The through groove extends vertically through the fixed arm, and the locking hole is located on the side of the fixed arm and communicates with the through groove. The moving rod is embedded in the through groove, and the locking hole is used to fix the moving rod by a locking element.

[0044] Specifically, refer to Figure 2 To secure the infrared probe to shellfish in different locations, the fixing arm 440 employs a telescopic structure, such as a telescopic rod. Several clamping components are mounted on the fixing arm 440 to hold the infrared probe. Each clamping component includes a movable rod 441 slidably connected to the fixing arm 440 in the vertical direction and a clamping member 442 mounted at the end of the movable rod 441. When using the fixing arm 440, the movable rod 441 extends into the test basin 500, allowing the clamping member 442 to clamp the infrared probe or a cable close to it. The closer the clamping member 442 is to the end of the infrared probe, the more stable the probe is during testing. During drilling, to avoid interference from the fixing arm 440, the movable rod 441 slides upwards and out of the height range of the test basin 500, then the fixing arm 440 is rotated relative to the mounting rod 420, moving it away from the test basin 500 area, thus not interfering with the operation of the drilling assembly 600. The clamping component 442 can be a tail clip or a butterfly clip, etc., and is connected to the moving rod 441 by fasteners or welding.

[0045] In this embodiment, the fixed arm 440 is provided with a through groove penetrating both the bottom and top surfaces, and the moving rod 441 is located within the through groove. The side of the fixed arm 440 is provided with a locking hole and a locking member 443 is installed thereon. The moving rod 441 is fixed within the through groove by the locking member 443. The moving rod 441 can move vertically within the through groove. The locking member 443 is threadedly connected to the locking hole and abuts against the moving rod 441, thereby fixing the moving rod 441.

[0046] In some alternative embodiments, the apparatus further includes a water bath located on a base, with a test basin located within the water bath, the water bath serving to maintain the temperature of the seawater in the test basin.

[0047] Specifically, refer to Figure 3In this embodiment, the device further includes a water bath 800; a test basin 500 is located within the water bath 800; and a water outlet 810 is provided at the bottom of the water bath 800. The water in the water bath 800 is used to heat or cool the seawater in the test basin 500, ensuring that the seawater in the test basin 500 remains at a low temperature during the test, thus better testing the oysters and preventing data deviations caused by changes in ambient temperature during the test. The water bath 800 can be connected to an external cold water supply device to achieve cold water circulation, keeping the water in the water bath at a relatively constant low temperature. The cold water supply device can be the seawater supply component 300 or other equipment such as a chiller 900.

[0048] In some alternative embodiments, the apparatus further includes a chiller, the outlet of which is connected to the inlet of the water bath, the chiller being used to provide chilled water at a constant temperature to the water bath.

[0049] Specifically, refer to Figure 3 Since cooling the seawater in the seawater supply component 300 is relatively difficult, in this embodiment, a chiller 900 is used to supply cold water to the water bath 800, referring to... Figure 3 The outlet pipe of the chiller 900 is connected to the water bath 800; the outlet 810 of the water bath 800 is connected to the inlet of the chiller 900 through the first pump body 910. The chiller 900 can be a laboratory chiller 900, which provides chilled water at a constant temperature to the water bath 800, and the chilled water in the water bath 800 can return to the inlet of the chiller 900 through the first pump body 910, realizing the circulation of chilled water.

[0050] In some alternative embodiments, the signal processing component includes a signal amplifier, a signal recording host, and a signal processing host.

[0051] Specifically, in this embodiment, the signal collected by the infrared sensor is processed by a signal amplifier and a signal recording host, and then transmitted to a signal processing host (such as a computer). Simultaneously, the relevant software in the signal processing host is used to set the frequency and range before measurement begins. The optical signal is input to the host for processing via the signal amplifier, resulting in a real-time displayed cardiac spectrum. After saving the spectrum, three segments are randomly selected to calculate the average heart rate.

[0052] In some alternative embodiments, the apparatus further includes an oxygen supply assembly for maintaining the oxygen content of the seawater in the test basin.

[0053] Specifically, in this embodiment, to ensure the stable vitality of the oysters, the oxygen content of the seawater in the test basin can be maintained by oxygenating the seawater in the test basin through an oxygen supply component.
