[0002] The multi-dimensional video monitoring camera generally refers to a 360° monitoring camera, which can eliminate monitoring blind spots and provide a large overall picture, and is therefore more commonly used in outdoor or important indoor places; it has a rotatable camera module, and a spherical protective cover is installed outside the camera module, which can effectively protect the camera module without affecting the monitoring field of view.

[0003] In order to obtain a larger monitoring field of view, the camera is installed at a higher position, and therefore: (1) When the camera is located at a higher position and is located in an outdoor scene, and in a less rainy season or region, dust adheres to the outer surface of the camera protective cover, affecting the camera image quality; (2) During daily use of the camera, if frequent regional intrusion detection, image recognition and other conditions occur, the energy consumption of the main control chip is high, and the heat generation is serious, which may indirectly cause the image thermal noise to increase and the electronic components to age faster, especially in the case of a large temperature difference between the inside and outside of the protective cover, causing fogging and condensation, affecting image capture.

[0004] To solve the above technical problems at the same time, the monitoring camera needs to have cleaning and rapid heat dissipation functions, and to achieve the same effect, the prior art has monitoring cameras with heat dissipation functions such as Chinese invention patent No. CN113225463B and the like, and monitoring cameras with cleaning functions such as Chinese invention patent No. CN115695996B and the like. The structure of the similar prior art is complex, and if both functions are added, the required floor space is larger, and the larger the size of the monitoring camera, the higher its visibility, especially for important places, if the concealment is lost, criminals can find and destroy it at the first time. In order to solve the above problems, we propose a multi-dimensional video monitoring camera. SUMMARY

DETAILED DESCRIPTION

[0042] In order to make the technical means, creative features, purposes and functions of the present application easy to understand, the present application will be further described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0043]

Embodiment one

[0044] Among them, the electronic components 3 with high power consumption in the monitoring camera are integrated between the heat conduction parts 41, the heat conduction parts 41 are annular structures, which form annular coverings for the electronic components 3, the heat conduction parts 41 are made of any material known to those skilled in the art, such as aluminum, copper or ceramic, which is easy to conduct heat and non-magnetic; The holding frame 42 is connected with a driving part 5 for driving the holding frame 42 to rotate, the driving part 5 mainly comprises an electric motor, which can have a speed reduction gear set, the electric motor is mainly a programmable motor such as a stepper motor or a servo motor, and the electric motor is controlled and driven by a main control chip in the monitoring camera; When the monitoring camera is used outdoors, the key parts such as the motor need to be waterproofed.

[0045] It should be noted that in the process of normal operation of the camera, the heat emitted by the electronic element 3 is transferred to the heat conduction piece 41, and at the same time, because the holding frame 42 is located on the outside, when the temperature of the heat conduction piece 41 is higher than the temperature of the holding frame 42, the heat is transferred from the heat conduction piece 41 to the holding frame 42. Normally, the holding frame 42 is in contact with the external air, and the heat loss speed of the holding frame 42 itself is greater than the heat emission speed of the electronic element 3.

[0046] In the embodiment, the inside of the holding frame 42 is also filled with liquid, which can be an easily heat-absorbing liquid such as pure water; When the inside of the holding frame 42 is filled with liquid, the heat on the holding frame 42 can be quickly and evenly distributed, which can effectively improve the heat conduction efficiency of the holding frame 42 and ensure the effective heat dissipation effect of the electronic element 3.

[0047] In the embodiment, the electronic element 3 with serious heat emission should be integrated on the inside of the heat conduction piece 41, such as a PCB with a main control chip, a power management module, etc. The structure and shape of the PCB are customized by those skilled in the art according to the actual situation, so they are not described in detail in this embodiment.

[0048]

Embodiment Two

[0049] Among them, the liquid is preferably a liquid such as pure water or pure water + cleaning liquid, and those skilled in the art can make a reasonable choice according to the actual use situation, and the liquid is preferably an easily heat-absorbing liquid.

[0050] It should be noted that the present application is a multi-dimensional video monitoring camera. If the surface of the protective cover 2 of the monitoring camera needs to be cleaned, the holding frame 42 needs to be rotated by the driving piece 5. As shown in Figure 10 The initial state of the holding frame 42 is the heat dissipation operation state. Under the driving action of the driving piece 5, the holding frame 42 moves to act on the outer wall of the protective cover 2. In this process, the liquid in the holding frame 42 is sprayed out to the protective cover 2 through the water spraying part 423 on the holding frame 42 to realize water washing; With the rotating action of the two holding frames 42, the overall outer wall of the protective cover 2 can be effectively cleaned. After cleaning, due to the semi-spherical shape of the protective cover 2 and the relative vertical installation state of the protective cover 2 in the installation position, part of the liquid remaining on the surface of the protective cover 2 after washing will flow along the outer wall of the protective cover 2 under the action of gravity until it drips.

[0051] For actual implementation, when there is stubborn dust adhering to the surface of the protective cover 2, multiple cleaning can be performed. Multiple cleaning refers to rotating the holding frame 42 multiple times, so that the liquid sprayed by the holding frame 42 can more comprehensively and effectively act on the surface of the protective cover 2 to achieve cleaning.

[0052] It is worth mentioning that due to the setting of the holding frame 42, when the holding frame 42 is located on the outside and rotates to contact the heat-conducting member 41, the holding frame 42 can form a cold-heat exchange with the heat-conducting member 41 to timely absorb the heat transferred from the electronic element 3 to the heat-conducting member 41. When the holding frame 42 rotates and acts on the surface of the protective cover 2, the liquid in the holding frame 42 can flow out and spray onto the surface of the protective cover 2 to achieve cleaning. On the one hand, the compact structure of the camera body can maximize the functions of cleaning and rapid heat dissipation. The compact structure is more suitable for hidden application scenarios. On the other hand, the control mechanism of the present application is simple and does not require multiple systems to work together. The manufacturing cost is relatively small, and the cost performance is maximized. Only by controlling the liquid flow in the holding frame 42 while changing the position of the holding frame 42 can the feedback delay of the electronic communication control mechanism be avoided, so that the liquid flow in the holding frame 42 can be utilized in a timely and effective manner, and excessive waste can be avoided.

[0053] In this embodiment, in order to achieve cleaning of the surface of the protective cover 2, the size of the holding frame 42 is small, and the liquid capacity stored in the holding frame 42 is small, which may not be enough to clean the surface of the protective cover 2. At this time, the holding frame 42 may need to be externally connected to a liquid supply system to meet the continuous liquid supply demand for cleaning the protective cover 2.

[0054] As a preferred embodiment, the holding frame 42 is externally connected to a liquid supply system to continuously supply liquid to the inside of the holding frame 42. The liquid supply system is any liquid supply system that can continuously supply liquid, such as a water tank, a pump, or a combination thereof, which is well known and understood by those skilled in the art. When the monitoring camera is used outdoors, an external water pipe can be connected. Those skilled in the art can make reasonable choices according to the actual use, and a small independent water tank is preferably configured. As when the monitoring camera is used indoors, considering the need for concealment, the mandrel 43 can be connected to the indoor system pipeline such as an automatic water spray fire extinguishing system through the communication member 6 without the need for an external small water tank.

[0055] In this embodiment, the liquid filled in the mandrel 42 is preferably pure water, which has a high specific heat capacity and is suitable for heat exchange. In addition, the impurities in the pure water are less after a certain period of heat exchange, which can be used for cleaning the protective cover 2. In this embodiment, those skilled in the art can understand that, according to the actual implementation, the composition of the liquid filled in the mandrel 42 can be selected, such as under the condition of proper storage, or under the premise that the liquid in the mandrel 42 is used frequently. The liquid in the mandrel 42 will not produce unnecessary impurities due to long-term storage in the mandrel 42 or contact with the external environment. At this time, the liquid in the mandrel 42 can be any single liquid or combination of several liquids that can be used for heat dissipation and cleaning functions, such as water + cleaner.

[0056]

Embodiment Three

[0057] Among them, the water spraying part can be a hole, or a mist spraying head is connected to the mandrel 42 to enhance the cleaning effect of the protective cover 2.

[0058] Further, the rotating reference position on the holder 42 is provided with a sleeve 421 coaxial with the rotating reference of the holder 42, a core shaft 43 is arranged in the inside of the sleeve 421 and is in communication with the external liquid supply system, and the sleeve 421 and the core shaft 43 are in a structure state after relative rotation, including a cleaning operation state and a heat dissipation operation state.

[0059] The sleeve 421 is fixedly connected with the holder 42, the sleeve 421 and the core shaft 43 are preferably in rotating dynamic sealing connection, and the core shaft 43 is fixed.

[0060] Further, a plurality of liquid inlets 4211 corresponding to the number of cavities in the holder 42 are arranged at the position where the sleeve 421 is connected with the holder 42, and each liquid inlet 4211 is in communication with the corresponding cavity. At least one water outlet 431 is arranged on the core shaft 43, and when the water outlet 431 is opposite to the liquid inlet 4211 attached to any cavity, the cavity and the core shaft 43 are in communication.

[0061] It should be noted that the present application is a multi-dimensional video monitoring camera, which is provided with a multifunctional heat dissipation piece 4. Figure 10 As shown in the heat dissipation operation state of the holder 42, one of the liquid inlets 4211 attached to the sleeve 421 on the holder 42 is not in communication with the water spraying part 423, and is in communication with the water outlet 431 on the core shaft 43 at this time, so that the external liquid enters the core shaft 43 through the connecting piece 6, and then enters the cavity in the holder 42 which is not in communication with the water spraying part 423 through the water outlet 431 on the core shaft 43 and the liquid inlet 4211 on the sleeve 421 which is not in communication with the water spraying part 423, so as to perform heat exchange. In the cleaning operation state of the holder 42, the holder 42 has been positionally transformed under the driving action of the driving piece 5, that is, the sleeve 421 on the holder 42 has been rotated relative to the core shaft 43, one of the liquid inlets 4211 on the sleeve 421 which is not in communication with the water spraying part 423 is no longer in communication with the water outlet 431 on the core shaft 43 at this time, and the other liquid inlet 4211 on the sleeve 421 which is in communication with the water spraying part 423 is in communication with the water outlet 431 on the core shaft 43 at this time, in this state, the external liquid enters the other cavity in the holder 42 which is in communication with the water spraying part 423 through the connecting piece 6, the core shaft 43 and the sleeve 421, and the liquid is sprayed out of the water spraying part 423 to the protective cover 2 for cleaning.

[0062] As a preferred embodiment, the chamber not communicated with the water spraying part 423 is located at the side adjacent to the heat conducting part 41, so that the chamber for heat dissipation is in direct contact with the heat conducting part 41, and the heat exchange between the heat conducting part 41 and the holding frame 42 is realized in the first time. In addition, the chamber for cleaning is spaced apart from the protective cover 2, so that the water spraying area is increased and the cleaning effect is ensured.

[0063] As a preferred embodiment, the holding frame 42 is matched with the structure of the protective cover 2, and the scraping part 424 is arranged on the side of the holding frame 42 adjacent to the protective cover 2. The protective cover 2 has a hemispherical structure, and the holding frame 42 has a ring structure. The scraping part 424 is made of soft material such as rubber or silica gel, which can be attached to the surface of the holding frame 42. On the one hand, the scraping part 424 can disturb the dust on the surface of the protective cover 2 during cleaning. On the other hand, the water droplets on the surface of the protective cover 2 can be scraped off by the scraping part 424 during cleaning, forming a thin water film that is easy to dry. The scraping part 424 made of water-absorbing material can be arranged on the side of the holding frame 42 away from the water spraying part 423, which can accelerate the drying of the cleaned protective cover 2. Among them, there are two holding frames 42 arranged in rotational symmetry. During the cleaning of the protective cover 2, only one holding frame 42 can be used, or two holding frames 42 can be used to rotate towards each other.

[0064] As a preferred embodiment, at least two water outlets 431 are arranged on the mandrel 43. The communication range of one water outlet 431 is larger than that of the other water outlet 431, and the two water outlets 431 are staggered in position. The water outlet 431 with a larger communication range can only communicate with the liquid inlet 4211 attached to the chamber communicated with the water spraying part 423, and the water outlet 431 with a smaller communication range can only communicate with the liquid inlet 4211 attached to the chamber not communicated with the water spraying part 423. Only one set of corresponding liquid inlets 4211 and water outlets 431 are communicated at the same time. The water outlet 431 with a larger communication range is arranged according to the following principle: during the rotation of the holding frame 42 along the surface of the protective cover 2, the chamber communicated with the water spraying part 423 is always communicated with the mandrel 43, so that the liquid supply can be maintained continuously. The two water outlets 431 staggered in position can be staggered in the circumferential direction of the mandrel 43, which is more consistent with the rotation transformation mechanism of the mandrel 43 itself.

[0065]

Embodiment Four

[0066] It should be noted that the present application is a multi-dimensional video monitoring camera, and when the liquid in the holding frame 42 needs to be replaced, the holding frame 42 also needs to be driven and controlled by the driving member 5, and as Figure 10 shown in the structure state, in the drainage state, the operation state of the holding frame 42 is a process of rotating upward, and the above embodiment is the same, when the holding frame 42 rotates to the drainage port 432 on the core shaft 43 and the liquid inlet 4211 on the sleeve 421 which is not communicated with the water spraying part 423, at this time the chamber which is not communicated with the water spraying part 423 is communicated with the outside, and the liquid is discharged through the liquid inlet 4211, the drainage port 432 and the drainage pipe 433, so as to realize the discharge of the liquid in the chamber adjacent to the heat conducting piece 41 in the holding frame 42; Then, at this time, the liquid in the chamber adjacent to the heat conducting piece 41 in the holding frame 42 needs to be refilled, and at the same time, the heat exchange demand of the heat conducting piece 41 is met, and the holding frame 42 is rotated and reset by the driving member 5, when the holding frame 42 rotates to the position state in the heat dissipation operation state, at this time the external liquid reenters the inside of the holding frame 42, and the heat dissipation is carried out.

[0067] In the embodiment, considering that the monitoring camera has less high-power consumption condition in actual implementation process, and because the structure of the holder 42 is compact and the liquid capacity in the holder 42 is less, the liquid in the holder 42 is directly discharged and then added, instead of being recycled; If the monitoring camera is used in a high-temperature environment or a scene that may frequently generate high power consumption, a small circulating device, such as a water tank + pump, can be selected to communicate between the external liquid supply system and the holder 42. The heat dissipation member, such as the heat dissipation fin, is installed on the external communication pipeline. Under the action of the heat dissipation member, the liquid in the holder 42 can be cooled and circulated by the natural circulation of external air.

[0068] In the present application, the control mechanism of the driving member 5 not mentioned, how to change the state of the holder 42? It belongs to the knowledge range that can be understood by those skilled in the art. Those skilled in the art can understand that when the monitoring camera frequently exists in the area intrusion detection, image recognition and other high-power consumption conditions, after a certain number of times, the holder 42 needs to be rotated and changed to the leakage state to replace the liquid in the holder 42. It can also be detected by the temperature and humidity sensor to detect the temperature of the liquid in the holder 42. When the temperature of the liquid in the holder 42 reaches the set threshold, the state of the holder 42 is changed. When the surface of the protective cover 2 is detected or monitored to be dirty, the holder 42 needs to be rotated and changed to the cleaning operation state to a certain extent. The starting method of the multifunctional heat dissipation member 4 can be manually started, or the image recognition algorithm can be preset for self-detection and start. Such control mechanism belongs to the known technology that can be known by those skilled in the art, so it is not described in detail here.

[0069] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
