[0024] Example:

[0025] Reference Figure 1 and Figure 2As shown, a hydrological measurement lead fish includes a streamlined main shell 1. A support 2 is installed through one end of the main shell 1 with a larger diameter, and a tail fin assembly 3 is installed at the other end. A pressure-holding chamber 4 is provided inside the main shell 1. The pressure-holding chamber 4 includes a chamber body and a cover. A pressure sensor 15, a control device 11, a battery 12, and a measuring sensor 13 are provided inside the chamber body. A flange 18 is provided on one side of the chamber body. An electrical signal input port 19 is provided in the middle of the flange 18. One end of the support 2 is connected to the flange 18. A data output pin 8 is provided on the cover. The control device 11 is electrically connected to the pressure sensor 15, the battery 12, the measuring sensor 13, the electrical signal input port 19, and the data output pin 8 through connecting cables 20.

[0026] A flow meter is mounted on bracket 2, while the tail fin assembly 3 improves the stability and maneuverability of the lead weight in water. A pressure chamber 4 is embedded in the main shell 1, and the pressure chamber 4 is sealed with a cover. A pressure sensor 15 is installed inside the pressure chamber 4. After the pressure chamber 4 is sealed, it is filled with positive pressure. By remotely viewing the air pressure data inside the pressure chamber 4 fed back by the pressure sensor 15, it is possible to determine whether the pressure chamber 4 is leaking. If the pressure drops, it indicates a leak; if the pressure remains constant, it indicates that the lead weight is operating normally. This greatly facilitates users in remotely checking for leaks while the lead weight is in operation, ensuring its proper use.

[0027] Pressure data in the pressure chamber 4 is measured by pressure sensor 15, battery 12 is used to power control device 11, and measurement sensor 13 allows users to select the corresponding sensor for measurement according to measurement needs. Electrical signal input port 19 is used to transmit the measurement data of flow meter to control device 11, and data output pin 8 remotely sends the data collected by control device 11 for remote viewing by users.

[0028] The hatch is equipped with a valve core 21.

[0029] The valve core 21 facilitates the injection of air into the pressure chamber 4, thereby filling the pressure chamber 4 with positive pressure. At the same time, the valve core 21 can also prevent air from leaking out of the pressure chamber 4.

[0030] The hatch is also equipped with a diving pressure gauge assembly 9. A protective shell 10 is provided on the surface of the hatch corresponding to the position of the diving pressure gauge assembly 9. A pressure observation window 1001 is provided on one side of the protective shell 10.

[0031] The diving pressure gauge assembly 9 facilitates the measurement of the diving depth of the lead fish during operation, ensuring the safety of the lead fish. The protective shell 10 protects the diving pressure gauge assembly 9 from damage, while the pressure observation window 1001 allows for viewing the data of the diving pressure gauge assembly 9 through the protective shell 10.

[0032] The tail fin assembly 3 includes an upper tail fin 303, a lower tail fin 302, and a horizontal tail fin 301. There are two horizontal tail fins 301, which are symmetrically arranged on the main body shell 1 and are horizontally arranged. The upper tail fin 303 is vertically arranged on the main body shell 1 and is perpendicular to the horizontal tail fin 301. The two horizontal tail fins 301 are symmetrical with respect to the upper tail fin 303. There are two lower tail fins 302, which are vertically arranged on the lower surface of the two horizontal tail fins 301 and are symmetrically arranged.

[0033] The two horizontal tail fins 301 work together to improve the stability of the lead car in the vertical plane, reduce swaying during operation, and improve propulsion efficiency, while the upper tail fin 303 and the two lower tail fins 302 work together to improve the stability of the lead car in the horizontal plane.

[0034] The combination of the upper tail fin 303, lower tail fin 302, and horizontal tail fin 301 not only improves the agility and speed of the lead carp, but also reduces noise.

[0035] The hatch has a through hole, and a mounting sleeve 5 is provided on the side wall of the hatch corresponding to the position of the through hole. A mounting cover 6 is provided on one end face of the mounting sleeve 5. A deep-sea aviation plug 7 is provided on the mounting cover 6. The data output pin 8 is located inside the deep-sea aviation plug 7. The pressure sensor 15 is located on one side of the mounting cover 6.

[0036] The deep-sea aviation plug 7 is installed separately on the mounting cover 6 of the mounting sleeve 5, which makes the use of the deep-sea aviation plug 7 more flexible and facilitates the disassembly and assembly of the pressure sensor 15 during maintenance. Since the cabin and the cover are fixed by a large number of bolts, separating the cabin and the cover would consume a lot of time and effort. Therefore, the mounting cover 6 simplifies the operation.

[0037] The side wall of the cabin is provided with a general electrical signal input port 16 and a touch signal input port 17, and the general electrical signal input port 16 and the touch signal input port 17 are respectively electrically connected to the control device 11.

[0038] This facilitates the connection of the control device 11 to other electronic devices inside the lead fish.

[0039] The side wall of the cabin is provided with a sensor mounting base 14, and the measuring sensor 13 is mounted on the sensor mounting base 14.

[0040] The sensor mounting base 14 facilitates sensor installation. After selecting the appropriate measurement sensor 13, the user removes the sensor mounting base 14 from the side wall of the cabin, then installs the measurement sensor 13 on the sensor mounting base 14, and then installs the sensor mounting base 14 on the side wall of the cabin. Since different measurement needs require the measurement sensor 13 to be replaced, opening the cabin cover to replace it each time would consume a lot of time. Therefore, the sensor mounting base 14 simplifies the operation and improves work efficiency.

[0041] A sealing ring is provided at the connection between the hatch cover and the pressure chamber 4.

[0042] The sealing ring improves the airtightness of the cover to the pressure tank 4, preventing water from entering the pressure tank 4.

[0043] When using the device, select the appropriate measuring sensor 13 according to the measurement requirements, install the measuring sensor 13 on the sensor mounting base 14, install the control device 11 of the lead fish, the battery 12 and other necessary electronic devices in the tank, install the pressure sensor 15 on the mounting cover 6, and connect the control device 11 to the pressure sensor 15, the battery 12, the measuring sensor 13, the electrical signal input port 19, the data output pin 8, the ordinary electrical signal input port 16 and the touch signal input port 17 respectively through the connecting cable 20.

[0044] Then, the hatch cover is installed on the cabin body to seal the pressure chamber 4. The mounting sleeve 5 is then sealed with the mounting cover 6. Air is then injected into the pressure chamber 4 through the valve core 21 on the hatch cover to maintain a positive pressure in the pressure chamber 4. The pressure sensor 15 monitors the pressure data in the pressure chamber 4 in real time and feeds the data back to the control device 11. The data is also sent to the remote control terminal through the data output pin 8. By remotely monitoring the data of the pressure sensor 15, the system can monitor whether the lead fish is leaking. If the pressure data of the pressure sensor 15 decreases, there is a leak in the pressure chamber 4, and water will seep into the pressure chamber 4. In this case, the lead fish will be stopped from working. If the pressure data of the pressure sensor 15 remains unchanged, it means that there is no leak in the lead fish and it can be used normally.

[0045] In actual use, the pressure chamber 4 also houses other electronic components. These electronic components are protected by the pressure-holding side to ensure that they do not come into contact with water, and if they do come into contact with water, it can be detected in time.

[0046] Support 2 is a hollow pipe. The lead wire of the flow meter passes through the inside of support 2 and is not exposed on the outside to avoid getting tangled in the water tank.

[0047] Sealing rings are provided at the connection between the hatch and the hull, at the location of the hull where the ordinary electrical signal input port 16, the touch signal input port 17, the electrical signal input port 19, the sensor mounting base 14, the valve core 21, the diving pressure gauge assembly 9, the protective shell 10, and at the connection between the mounting cover 6 and the mounting sleeve 5; while the data output pin 8 and the deep-sea aviation plug 7 are sealed with glass sintering.

[0048] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
