Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nuclear energy, and in particular relates to a radiation-resistant pan / tilt platform and monitoring equipment used underwater. Background Art
[0002] In the field of nuclear energy technology, video surveillance of underwater radiation environments places high demands on technology. When monitoring underwater fuel components or equipment, not only must the monitoring equipment be waterproof and radiation-resistant, but it must also adapt to confined inspection spaces. Therefore, the monitoring equipment must be miniaturized and capable of operating in radiation environments without disrupting nuclear equipment operations. Currently, two main approaches are used for video surveillance of underwater radiation environments. The first involves filling the cavity of the monitoring equipment with grease to protect components. However, this approach can easily introduce grease into the water, affecting water quality. This is particularly unacceptable in boric acid water used in nuclear power plants. The second solution is to use multiple silicone parts and oil seals to seal the cavity of the monitoring equipment, and then flush high-pressure gas into the cavity to balance the water pressure of the monitoring equipment during underwater operation, ensure the pressure balance inside and outside the cavity, and prevent water from entering the equipment. However, during operation, the gas inside the monitoring equipment will slowly leak out. When the air pressure inside the cavity drops to a certain level, the pressure difference between the inside and outside can no longer be balanced. In order to ensure that the monitoring equipment is not damaged, the monitoring equipment must be taken out of the water and then a certain pressure of gas must be flushed into the monitoring equipment before it can work in the water again. Therefore, it cannot work normally underwater for a long time, and an air pump is required during use, which is inconvenient to operate. Utility Model Content

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0028] This embodiment provides a radiation-resistant pan / tilt platform for underwater use. Figure 1 A schematic diagram of the external structure of an underwater radiation-resistant pan / tilt platform provided in this embodiment. Figure 2 This is a schematic diagram of the internal structure of an underwater radiation-resistant pan / tilt platform provided in this embodiment.
[0029] like Figure 1 and Figure 2As shown, the radiation-resistant pan / tilt platform for underwater use in this embodiment includes: a main body 1, a first rotating part 2, a second rotating part 3, a core component 4, and a control module 5. The main body 1 is connected to the first rotating part 2, and the first rotating part 2 can drive the main body 1 to rotate in a first direction. The second rotating part 3 is connected to the main body 1. The second rotating part 3 can rotate on the main body 1 along a second direction. The core component 4 is arranged on the second rotating part 3. The main body 1 includes a shielding shell 6. The control module 5 is arranged in the shielding shell 6. The control module 5 is sealed and connected to the first rotating part 2, the second rotating part 3, and the core component 4 respectively.
[0030] In this embodiment, if Figure 1 and Figure 2 As shown, the first direction and the second direction form an angle. Preferably, the first direction is horizontal and the second direction is vertical. The first rotating portion 2 can drive the main body 1 to rotate back and forth between 0° and 359° in the horizontal direction. The second rotating portion 3 can drive the core component 4 to rotate back and forth between -90° and 90° in the vertical direction on the main body 1. This meets the monitoring needs of multiple directions and angles.
[0031] In this embodiment, if Figure 2 As shown, the control module 5 includes a printed circuit board (PCB board), which has a compact structure, occupies a small space, and can be safely and stably sealed in the shielding shell 6.
[0032] The underwater radiation-resistant pan / tilt head of this embodiment includes a main body 1, a first rotating part 2, a second rotating part 3, a core component 4, and a control module 5. The main body 1 includes a shielding housing 6. The control module 5 is disposed within the shielding housing 6. The control module 5 is sealedly connected to the first rotating part 2, the second rotating part 3, and the core component 4, respectively. The first rotating part 2 can drive the main body 1 to rotate in a first direction. The second rotating part 3 can rotate on the main body 1 in a second direction. The core component 4 is disposed on the second rotating part 3. In other words, only the main body 1 supports the core component 4 and drives it to rotate in the first and second directions, achieving a single-arm structure and eliminating one arm. This facilitates the miniaturization of the underwater radiation-resistant pan / tilt head and facilitates its use in confined workspaces. In this solution, the control module 5 is disposed within the shielding housing 6, which provides both radiation shielding and waterproofing for the control module 5. Therefore, water can enter the main body 1 directly, eliminating the need for oil seals or air pressure seals, thereby preventing water contamination and enabling long-term underwater operation.
[0033] In some embodiments, as Figure 1 and Figure 2As shown, the main body 1 includes: a main shell 11, an upper cover 12, and a side cover 13. The main shell 11 includes an upper cavity and a lower cavity that are interconnected. A first opening is provided at the top of the upper cavity. A second opening is provided on the side wall of the lower cavity. The upper cover 12 is provided on the first opening. The side cover 13 is provided on the second opening. The first rotating part 2 is inserted into the upper cavity. The second rotating part 3 is inserted into the lower cavity. The shielding shell 6 is located at the connection between the upper cavity and the lower cavity.
[0034] In this embodiment, Figure 2 As shown, the upper chamber has a larger accommodating space and is approximately in shape of a cube, while the lower chamber is narrower and is approximately in shape of a cuboid. This arrangement is beneficial to reducing the volume of the main body 1 and further achieving miniaturization.
[0035] The main body 1 of this embodiment comprises a main housing 11, an upper cover 12, and a side cover 13. The cavity formed by the main housing 11, upper cover 12, and side cover 13 comprises an upper cavity and a lower cavity that are interconnected. A first opening is provided at the top of the upper cavity to facilitate the assembly of the first rotating part 2. A second opening is provided on the side wall of the cavity to facilitate the assembly of the second rotating part 3. The upper cover 12 is placed above the first opening, and the side cover 13 is placed above the second opening, which helps improve the integrity of the device.
[0036] In some embodiments, as Figure 2 As shown, the first rotating portion 2 includes a first rotating shaft 21, at least one first bearing 22, and a first drive assembly. The first bearing 21 is disposed on the main body 1. The main body 1 is rotatably mounted on the first rotating shaft 21 via the first bearing 22. A first drive assembly is disposed within the main body 1. The first drive assembly is capable of driving the main body 1 to reciprocate about the first rotating shaft 21. A control module 5 is connected to the first drive assembly.
[0037] In this embodiment, if Figure 2 As shown, in order to improve vertical stability, the first shaft 21 is designed to be stepped, including a large diameter section and a small diameter section connected to each other. Two first bearings 22 are installed, and are located on the large diameter section and the small diameter section of the first shaft 21 respectively.
[0038] In this embodiment, if Figure 2 As shown, the first drive assembly includes a first worm gear 23, a first worm 24, and a first motor 25. The first worm gear 23 is rotatably mounted on the first rotating shaft 21 and is fixedly connected to the main body 1. The first motor 25 drives the first worm gear 23 to rotate on the first rotating shaft 21 via the first worm 24, thereby driving the main body 1 to reciprocate in a first direction. A first motor cable 26 of the first motor 25 is connected between the control module 5 and the first motor 25.
[0039] In this embodiment, if Figure 2As shown in FIG, the first rotation axis 21 is arranged in the vertical direction. In this way, when the main body 1 rotates around the first rotation axis 21, the main body 1 rotates in the horizontal direction.
[0040] The first rotating portion 2 of this embodiment includes a first rotating shaft 21, at least one first bearing 22, and a first drive assembly. The main body 1 is rotatably mounted on the first rotating shaft 21 via the first bearing 22. The first drive assembly drives the main body 1 to rotate about the first rotating shaft 21. This simple and compact structure facilitates miniaturization of the pan / tilt head while ensuring stable operation.
[0041] In some embodiments, as Figure 2 As shown, a first through hole is provided on the first rotating shaft 21. The first through hole extends through the first rotating shaft 21 along its axis. The tail wire 7 of the control module 5 is connected to the outside through the first through hole. The tail wire 7 is sealed to the inner wall of the first through hole by potting glue.
[0042] In this embodiment, if Figure 2 As shown, in order to ensure the stability of the tail wire 7 in the first rotating shaft 21 , a compression nut is provided at the end of the first rotating shaft 21 to press the tail wire 7 onto the first rotating shaft 21 .
[0043] The tail wire 7 of this embodiment extends outside the main body 1 through the first through hole on the first rotating shaft 21 to connect to external equipment, and is sealed between the tail wire 7 and the inner wall of the first through hole by glue potting, which can not only improve the stability of the installation of the tail wire 7, but also achieve static sealing of the first through hole, with high reliability.
[0044] In some embodiments, as Figure 2 As shown, the second rotating portion 3 includes at least one second bearing 32, a second rotating shaft 31, and a second drive assembly. The second bearing 32 is disposed on the main body 1. The second rotating shaft 31 is rotatably disposed in the second bearing 32. A second drive assembly is disposed in the main body 1. The second drive assembly is capable of driving the second rotating shaft 31 to reciprocate in the second bearing 32. The control module 5 is connected to the second drive assembly. The movement component 4 is connected to the end of the second rotating shaft 31 located outside the main body 1.
[0045] In this embodiment, if Figure 2 As shown, in order to improve the stability of rotation, two second bearings 32 are provided, and are sequentially arranged on the middle section of the second bearing 31. In this way, the two second bearings 32 can balance and support the second rotating shaft 31, ensuring the smooth rotation of the second rotating shaft 31.
[0046] In this embodiment, if Figure 2As shown, the second drive assembly includes a second worm gear 33, a second worm 34, and a second motor 35. The second worm gear 33 is fixedly mounted on the second rotating shaft 31. The second motor 35 drives the second rotating shaft 31 through the transmission of the second worm 34 and the second worm gear 33, thereby driving the core component 4 to reciprocate in the second direction. A second motor cable 36 of the second motor 35 is connected between the control module 5 and the second motor 35.
[0047] In this embodiment, Figure 2 As shown, the second rotating shaft 31 is arranged in the horizontal direction. In this way, when the core component 4 rotates around the second rotating shaft 31, the core component 4 rotates in the vertical direction.
[0048] The second rotating unit (3) of this embodiment includes a second rotating shaft (31), at least one second bearing (32), and a second drive assembly. The second rotating shaft (31) is rotatably mounted on the main body (1) via the second bearing (32). The second drive assembly drives the second rotating shaft (31), which in turn drives the movement (4). This simple and compact structure facilitates miniaturization of the pan / tilt head (PTZ) while ensuring stable operation.
[0049] In some embodiments, as Figure 2 As shown, a second through hole is provided on the second rotating shaft 31. The second through hole passes through the second rotating shaft 31 along its axis. The connecting wire 8 of the core component 4 is connected to the control module 5 through the second through hole. The connecting wire 8 is sealed to the inner wall of the second through hole by glue filling.
[0050] In this embodiment, if Figure 2 As shown, in order to ensure the stability of the connecting wire 8 in the second rotating shaft 31 , a compression nut is provided at the end of the second rotating shaft 31 to press the connecting wire 8 onto the second rotating shaft 31 .
[0051] In this embodiment, the connecting wire 8 extends into the main body 1 through the second through hole on the second rotating shaft 31 to connect to the control module 5, and is sealed between the connecting wire 8 and the inner wall of the second through hole by glue filling, which can not only improve the stability of the installation of the connecting wire 8, but also achieve static sealing of the second through hole, that is, static sealing of the wiring port of the movement component 4 is achieved, and the reliability is high.
[0052] In some embodiments, as Figure 1 and Figure 2 As shown, the core component 4 includes an optical sensor circuit and a fill light.
[0053] The core component 4 of this embodiment includes an optical sensor circuit and a fill light, which facilitates the quick installation of the lens and can be used in dim underwater environments.
[0054] In some embodiments, as Figure 1 and Figure 2As shown, a connector is provided on the shielding shell 6. The control module 5 is connected to the first rotating part 2, the second rotating part 3 and the core component 4 through the connector. The connection between the connector and the first rotating part 2, the second rotating part 3 and the core component 4 is wrapped with a sealant layer.
[0055] This embodiment uses a plug-in connector as the interface connecting the control module 5 with the first rotating part 2, the second rotating part 3, and the core component 4, facilitating installation. The plug-in connector serves as an interface that not only transmits electrical signals and power but also provides a filtering function. In complex electronic devices, it can connect various subsystems or circuits. A sealant layer is wrapped around the connection between the plug-in connector and the first rotating part 2, the second rotating part 3, and the core component 4, preventing the wiring from falling off while achieving a static seal at the connection, resulting in a strong and reliable structure.
[0056] In some embodiments, as Figure 1 and Figure 2 As shown, the material of the shielding shell 6 is tungsten steel. The shielding shell 6 of this embodiment is made of tungsten steel, which has good shielding ability, corrosion resistance, and durability.
[0057] In addition, the shielding shell 6 of this embodiment is used to accommodate the control module 5. In the assembled type, after the control module 5 is placed in the shielding shell 6, the opening on the shielding shell 6 can be closed by welding, or the opening on the shielding shell 6 can be sealed by bolts, nuts and sealing rings.
[0058] The above describes the underwater radiation-resistant pan / tilt head of this embodiment. This embodiment achieves a miniaturized design and compact structure, reduces the need for waterproof space, reduces the risk of water leakage, and meets the requirements for long-term underwater operation of radiation-resistant cameras.
[0059] The installation method of this embodiment is as follows:
[0060] (1) Installation of the first rotating part 2
[0061] Step 1: First, tighten the tail wire 7 onto the first rotating shaft 21 through a tightening nut to form a tail wire assembly.
[0062] Step 2: Place the two first bearings 22 into the bearing grooves of the upper cover 12 , and then insert the first rotating shaft 21 into the bearing hole of the upper cover 12 .
[0063] Step 3: rotatably mount the first worm wheel 23 on the first rotating shaft 21 and fixedly connect it to the upper cover 12, and fix the first worm 24 in the main body 1 through the worm bracket to form an integrated worm wheel assembly.
[0064] Finally: the first motor 25 is installed on the worm bracket and connected to the first worm 24 through a synchronous belt to form an integral transmission component.
[0065] (2) Installation of the main body 1 and the second rotating part 3
[0066] The first step: fix the control module 5 in a radiation-resistant shielding shell 6 , and then fix the shielding shell 6 in the main body 1 .
[0067] Step 2: Install the core component 4 on the second rotating shaft 31, and insert the second rotating shaft 31 into the main body 1 with the second bearing 32 installed, install the second worm gear 33 and the second worm 34, and fix the second motor 35 in the main body 1.
[0068] The third step is to install the fill light and movement of the movement component 4.
[0069] (3) Connect the tail wire 7, connecting wire 8, first motor wire 26, and second motor wire 36 to the control module 5 in the shielded housing 6 through connectors. Secure the side cover 13 to the main housing 11 with screws to complete the installation. The tail wire 7, connecting wire 8, first motor wire 26, and second motor wire 36 all use K1-rated cables.
[0070] (4) Waterproof and shielding design
[0071] Each motor and bearing is waterproof. The tail wire 7, connecting wire 8, first motor wire 26, and second motor wire 36 are each connected to the control module 5 in the shielded housing 6 via connectors, and the connections are then sealed with glue. Each cable sheath is waterproof; as long as the core is covered by the sheath, the cables exposed outside the shielded housing 6 are waterproof. The first through-hole of the first rotating shaft 21 through which the tail wire 7 passes is also sealed with glue, as is the second through-hole of the second rotating shaft 31 through which the connecting wire 8 passes. This creates a static seal between the tail wire connection port and the interface with the motor.
[0072] This embodiment also provides a monitoring device, comprising: the aforementioned radiation-resistant pan / tilt platform for underwater use and a lens. The lens is mounted on a core component.
[0073] The monitoring equipment of this embodiment includes the above-mentioned radiation-resistant pan / tilt head for underwater use, so it can be used in a small working space, will not pollute the water quality, and can work underwater for a long time.
[0074] This embodiment of the monitoring device provides a compact, miniaturized, radiation-resistant underwater single-arm pan-tilt camera structure. The core component 4 is statically sealed using glue potting, while the control module 5 is also integrated with waterproofing and radiation resistance. Static sealing is achieved through a shielding shell 6 and a sealant layer. This reduces the required waterproofing space, minimizes the risk of water leakage, and meets the requirements for long-term underwater operation. Actual testing shows that this structural design can withstand gamma ray irradiation of 10^3 Gy / h, and the structure and waterproofing functions remain normal after a cumulative dose of 10^5 Gy.
