Description

Technical Field

[0001] This utility model relates to the field of camera technology in high-radiation environments, and more specifically, to a radiation-resistant camera with a quick-release structure. Background Technology

[0002] In recent years, my country's nuclear industry has developed rapidly, forming a nuclear energy industrial chain that extends from uranium exploration and mining to nuclear fuel production and supply, nuclear power plant construction and operation, and finally spent fuel processing. To enable remote monitoring and operation of key equipment, areas, and processes in the nuclear industry, a certain number of radiation-resistant cameras are required in high-radiation environments such as nuclear power plant reactor buildings, nuclear waste storage areas, and spent fuel processing workshops.

[0003] In high-radiation environments, radiation-resistant cameras have a longer lifespan compared to other cameras, but they still require regular maintenance and replacement. Traditional camera installation methods typically involve fixing them to walls or other objects with bolts, which takes a long time. In normal environments, this has little impact, but in high-radiation environments, the longer the installation time, the more difficult it is to guarantee the operator's personal safety. Therefore, it is necessary to provide a radiation-resistant camera that can improve the speed of installation and disassembly. Utility Model Content

[0004] The main objective of this invention is to propose a radiation-resistant camera with a quick-assembly structure to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model proposes a radiation-resistant camera with a quick-release structure, comprising:

[0006] The camera itself;

[0007] The connector is located on the top of the camera body and has an insertion end.

[0008] The base has a slot for the insertion end of the connector to be inserted.

[0009] And a locking part, which is provided on the base;

[0010] The locking part is used to lock or release the connector after it is inserted into the base.

[0011] In the above technical solution, the locking part is a press-lock structure. By pressing the locking part, the insertion end of the connector can be released in the base. After the external force pressing the locking part is removed, the insertion end of the connector is locked in the base.

[0012] In any of the above technical solutions, further, a locking hole is provided on the insertion end of the connector, and a mounting hole communicating with the slot is provided on the side end of the base; the locking part includes:

[0013] A locking bar with a locking hook is movably mounted in a mounting hole, with one end of the locking bar extending into a slot and the other end extending out of the base;

[0014] And an elastic reset component, used to drive the locking lever to move and reset;

[0015] When the connector is inserted into the base, the elastic reset member can drive the locking rod to move, so that the locking hook of the locking rod extends into the locking hole of the connector to prevent the connector from detaching from the base; when the locking rod is pressed, the elastic reset member is squeezed and the locking rod moves, and the locking hook of the locking rod disengages from the locking hole, so that the connector is freed from restriction.

[0016] In any of the above technical solutions, further, the inner wall of the mounting hole has a mounting groove that is radially outward, and the elastic reset element is a reset spring sleeved on the locking rod and located in the mounting groove.

[0017] In any of the above technical solutions, further, the outer wall of the locking rod has an annular baffle arranged radially outward, the annular baffle is located in the mounting groove, one end of the reset spring is pressed against the annular baffle, and the other end is pressed against the bottom of the mounting groove.

[0018] In any of the above technical solutions, the locking part further includes:

[0019] The pressure cap has a T-shaped hollow structure. The pressure cap is fitted onto the end of the locking rod that extends out of the base, and the large end of the pressure cap is threadedly connected to the mounting hole of the base.

[0020] Under normal conditions, the return spring applies an external force to the annular baffle, causing the locking rod to move and the annular baffle to press against the pressure plate.

[0021] In any of the above technical solutions, the lock hook further has a guide slope. During the process of inserting the connector into the base, the insertion end can apply an external force to the guide slope of the lock hook, so that the elastic reset member is compressed and the lock rod moves. After full insertion, the lock hook is aligned with the lock hole of the insertion end. The elastic reset member resets the lock rod and the lock hook is inserted into the lock hole of the insertion end.

[0022] In any of the above technical solutions, the locking rod has a strip groove along its length, and the base has a first limiting hole that communicates with the strip groove. A first limiting rod with its end extending into the strip groove is provided in the first limiting hole, and the first limiting rod is used to limit the rotation of the locking rod.

[0023] In any of the above technical solutions, a second limiting rod is further provided on the connector head, and a second limiting hole is provided on the base for the second limiting rod to be inserted.

[0024] In any of the above technical solutions, there are at least two insertion ends, which are evenly distributed on the connector head in the circumferential direction. The number of locking parts is the same as the number of insertion ends, and they are used to lock or release each insertion end respectively.

[0025] Beneficial effects: Compared with existing technologies, the quick locking and unlocking achieved by pressing is very convenient and practical for quick mounting of the camera body. Attached Figure Description

[0042] Radiation-resistant cameras are specialized imaging devices designed for high-radiation environments (such as nuclear power plants and nuclear waste treatment facilities), capable of stable operation under strong ionizing radiation conditions. They primarily utilize shielding materials (such as lead and tungsten alloys) to protect core components, or employ radiation-hardened semiconductor materials. Addressing the issue of existing radiation-resistant cameras lacking quick-release functionality, resulting in time-consuming assembly and disassembly, this paper proposes a radiation-resistant camera with a quick-release structure.

[0043] The radiation-resistant camera with a quick-assembly structure of this application will be described in detail below through the following embodiments.

[0044] Example 1:

[0045] like Figures 1-8 As shown, this embodiment proposes a radiation-resistant camera with a quick-release structure, including: a camera body 1; a connector 2 disposed on the top of the camera body 1, the connector 2 having an insertion end 23; a base 3 having a slot 31 for the insertion end 23 of the connector 2 to be inserted; and a locking part 4 disposed on the base 3.

[0046] In this configuration, after the connector 2 is inserted into the base 3, the locking part 4 is used to lock or release the connector 2 on the base 3.

[0047] Conventional cameras are typically mounted on walls or other structures using bolts and other components. Specifically, the camera head is fitted with a flange, which is then bolted to the wall, thus securing the camera.

[0048] To improve installation efficiency, this embodiment includes a connector 2, a base 3, and a locking part 4. The connector 2 is directly fixed to the head of the camera body 1. The base 3 is fixed to a wall or bracket. The locking part 4 is installed inside the base 3. Each time the camera is replaced, simply open the locking part 4, remove the camera body 1 and connector 2 from the base 3, and then take out the new camera body 1, which is already equipped with the connector 2. Then, insert the new camera body 1 into the base 3 through the connector 2 to replace the camera. This is very convenient and not only greatly reduces the camera replacement time, but also reduces the number of parts used and the use of bolts (in a nuclear radiation environment, if a bolt on the camera falls off, staff need to be arranged to immediately collect the fallen bolt, one factor being that the bolt surface may have adsorbed radioactive dust, which may cause secondary pollution when it falls off).

[0049] Specifically, the locking part 4 is a push-lock structure. By pressing the locking part 4, the insertion end 23 of the connector 2 can be released in the base 3. After the external force pressing the locking part 4 is removed, the insertion end 23 of the connector 2 is locked in the base 3.

[0050] The push-lock structure is a mechanical structure that achieves quick locking and unlocking through a pressing action. Using this type of structure to achieve quick mounting of the camera body 1 is very convenient and practical.

[0051] In this embodiment, it should be noted that there are at least two insertion ends 23, which are evenly distributed on the connector 2 in the circumferential direction. The number of locking parts 4 is the same as the number of insertion ends 23, and they are used to lock or release each insertion end 23 respectively.

[0052] One insertion end 23 is paired with one locking part 4. If only one set is used, the force between the connector 2 and the base 3 will be uneven. Therefore, at least two sets can be set and evenly distributed in the circumference. Under the action of multiple insertion ends 23 and multiple locking parts 4, the connection strength between the connector 2 and the base 3 is effectively improved.

[0053] Of course, setting up two sets is the better option. The two push-button lock structures are symmetrically arranged, and when disassembling, it can be operated with one hand. You can unlock it by pressing with your thumb and forefinger at the same time, which is very convenient.

[0054] In this embodiment, it should be noted that the cable on the camera body 1 passes through the hole in the middle of the connector 2 and also has a hole structure on the base 3. The aviation plug extends out from the base 3. Before the connector 2 and the base 3 are connected, the cable on the camera body 1 is first plugged into the aviation plug to power on the camera body 1 so that it can work normally. Then the connector 2 is inserted into the base 3 to complete the quick installation.

[0055] Example 2:

[0056] This embodiment is a further improvement based on Embodiment 1.

[0057] like Figures 4-8 As shown, in this embodiment, the insertion end 23 of the connector 2 is provided with a locking hole 231, and the side end of the base 3 is provided with a mounting hole 32 that communicates with the slot 31.

[0058] The locking part 4 includes: a locking rod 41 with a locking hook 411, the locking rod 41 being movably disposed in the mounting hole 32, with one end of the locking rod 411 extending into the slot 31 and the other end extending out of the base 3; and an elastic reset member 42 for driving the locking rod 41 to move and reset.

[0059] When the connector 2 is inserted into the base 3, the elastic reset member 42 can drive the locking rod 41 to move, so that the locking hook 411 of the locking rod 41 extends into the locking hole 231 of the connector 2 to prevent the connector 2 from detaching from the base 3; when the locking rod 41 is pressed, the elastic reset member 42 is squeezed and the locking rod 41 moves, and the locking hook 411 of the locking rod 41 disengages from the locking hole 231, so that the connector 2 is freed from restriction.

[0060] The connector 2 includes a sleeve and a flange 22 fixedly fitted onto the sleeve. One end of the sleeve is inserted and fixed to the head of the camera body 1, and the other end of the sleeve has threads for connecting an aviation plug. After the cable of the camera body 1 is inserted into the aviation plug, the aviation plug is then fixed in the sleeve by a threaded connection to prevent the aviation plug from loosening.

[0061] The insertion end 23 is a plate-like structure extending from the end face of the flange 22, with a through lock hole 231 on its side. The locking rod 41 is a round rod structure, and the locking hook 411 on it is formed by a slot. Specifically, there is a first slot 401 in the radial direction on the side wall of the locking rod 41, which passes through the locking rod 41 from front to back. Then, a second slot 402 is opened in the axial direction on the side wall of the first slot 401, which also passes through the locking rod 41 from front to back. The first slot 401 and the second slot 402 together form an L-shaped slot structure, in which the protruding part on the locking rod 41 forms the locking hook 411.

[0062] When the insertion end 23 of connector 2 is inserted into the slot 31 of base 3, the locking hook 411 on locking rod 41 is aligned with the locking hole 231 of insertion end 23. Under the action of elastic reset member 42, locking rod 41 can move, and locking hook 411 gradually extends into locking hole 231. At this time, under the action of locking hook 411, insertion end 23 cannot be disengaged from slot 31. After pressing the protruding end of locking rod 41, locking rod 41 can move, and locking hook 411 gradually disengages from locking hole 231. At the same time, elastic reset member 42 is compressed. After locking hook 411 is completely disengaged from locking hole 231, connector 2 can be easily removed from base 3. Of course, after the external force pressing locking rod 41 is lost, elastic reset member 42 is released, and its elasticity causes locking rod 41 to move and reset, and simultaneously causes locking hook 411 to re-insert into locking hole 231. In this way, quick insertion of connector 2 and base 3 can be achieved.

[0063] In this embodiment, it should be noted that the slot 31 is an annular groove, and the insertion end 23 is an arc-shaped plate that is adapted to the annular groove.

[0064] In this embodiment, the inner wall of the mounting hole 32 has a radially outwardly opening mounting groove 33, and the elastic reset member 42 is a reset spring sleeved on the locking rod 41 and located within the mounting groove 33. The automatic reset of the locking rod 41 is achieved by utilizing the elastic force of the spring.

[0065] In this embodiment, it should be noted that the outer wall of the locking rod 41 has a radially outwardly arranged annular baffle 412. The annular baffle 412 is located inside the mounting groove 33. One end of the return spring abuts against the annular baffle 412, and the other end abuts against the bottom of the mounting groove 33. By providing the annular baffle 412, the installation of the return spring is facilitated, and under the action of the annular baffle 412, the elastic force of the return spring can be evenly applied to the locking rod 41.

[0066] In this embodiment, it should also be noted that the locking part 4 further includes: a pressure cover 43, which is a T-shaped hollow structure. The pressure cover 43 is sleeved on one end of the locking rod 41 that extends out of the base 3, and the large end of the pressure cover 43 is threadedly connected to the mounting hole 32 of the base 3.

[0067] Under normal conditions, the return spring applies an external force to the annular baffle 412, causing the locking rod 41 to move and the annular baffle 412 to press against the pressure cover 43.

[0068] The pressure cap 43 is a cover plate structure installed at the mounting hole 32, used to limit the locking rod 41 and securely assemble it at the mounting hole 32.

[0069] Example 3:

[0070] This embodiment is a further improvement based on Embodiment 2.

[0071] like Figure 6 and Figure 7 As shown, in this embodiment, the locking hook 411 has a guide slope 4111. During the process of inserting the connector 2 into the base 3, the insertion end 23 can apply an external force to the guide slope 4111 of the locking hook 411, so that the elastic reset member 42 is compressed and the locking rod 41 moves. After being fully inserted, the locking hook 411 is directly opposite the locking hole 231 of the insertion end 23. The elastic reset member 42 resets the locking rod 41 and the locking hook 411 is inserted into the locking hole 231 of the insertion end 23.

[0072] The end of the locking hook 411 is cut at an angle to form a bevel, which forms a guide bevel 4111. When the insertion end 23 is inserted into the slot 31, the end of the insertion end 23 will gradually contact the guide bevel 4111 and apply an external force to the guide bevel 4111. This external force will cause the locking rod 41 to move, so that the locking hook 411 moves from directly below the insertion end 23 to the side. Finally, when the insertion end 23 is fully inserted into the slot 31, the locking hook 411 is embedded into the lock hole 231 under the action of the return spring, achieving a quick insertion effect.

[0073] Example 4:

[0074] This embodiment is a further improvement based on Embodiment 2 or Embodiment 3.

[0075] like Figure 6 As shown, in this embodiment, the locking rod 41 has a strip groove 403 opened along its length direction, and the base 3 has a first limiting hole that communicates with the strip groove 403. A first limiting rod 44 with its end extending into the strip groove 403 is provided in the first limiting hole. The first limiting rod 44 is used to limit the rotation of the locking rod 41.

[0076] When the insertion end 23 of the connector 2 is inserted into the slot 31 of the base 3, the locking hook 411 of the locking rod 41 needs to be aligned with the insertion end 23. Therefore, in order to prevent the locking rod 41 from rotating and thus preventing the insertion end 23 from being inserted smoothly, a strip groove 403 and a first limiting rod 44 are provided. The first limiting rod 44 is a pin structure, and its end is inserted into the strip groove 403. Under the limitation of the pin structure, the locking rod 41 cannot rotate, thereby ensuring that the insertion end 23 can be inserted smoothly.

[0077] Example 5:

[0078] This embodiment is a further improvement based on Embodiments 2, 3, or 4.

[0079] like Figure 3 , Figure 8As shown, in this embodiment, the connector 2 is provided with a second limiting rod 24, and the base 3 is provided with a second limiting hole 34 for the second limiting rod 24 to be inserted.

[0080] The longer the locking hole 231 of the insertion end 23 on the connector 2, the easier it is for the locking hole 231 to align with the locking hook 411. However, in practice, when the locking hole 231 is set to be longer, the connector 2 and the base 3 can rotate. This rotation will affect the camera's field of view to some extent (if a deflection occurs during operation, the shooting area will shift to some extent, which may result in a small area that needs to be shot not being captured properly). Therefore, a second limiting rod 24 is provided. The length of the second limiting rod 24 is set according to actual needs. Specifically, it is necessary to make it convenient for the operator to observe the positions of the second limiting rod 24 and the second limiting hole 34 at the same time, so that the second limiting rod 24 can be smoothly inserted into the second limiting hole 34.

[0081] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
