Description

Technical Field

[0001] The invention belongs to the technical field of monitoring equipment, and in particular relates to a monitoring and security equipment used in a factory. Background Art

[0002] The security monitoring system can replace manual monitoring for a long time in harsh environments, allowing people to see everything that actually happens at the monitored site and record it through security cameras.

[0003] However, after rain, rainwater tends to become water droplets under tension and remain at the bottom of the transparent protective cover at the bottom of the camera. At this time, the raindrops at the bottom of the transparent protective cover will block part of the camera lens, causing blind spots in monitoring and affecting normal monitoring.

[0004] A Chinese patent with the authorization announcement number CN212086291U discloses an intelligent security monitoring device for factories, including a video monitoring part, a water stain removal part and a supporting and fixing part. The video monitoring part includes a housing, a camera body and a camera protective cover. The camera body is installed at the bottom end of the housing, and the camera protective cover is arranged outside the camera body, and the camera protective cover is fixedly installed at the bottom of the housing. The water stain removal part includes a side shell, an air pump, a nozzle and a connecting pipe. High-pressure gas enters the cavity from the connecting pipe and is finally ejected from the nozzle. The gas ejected from the nozzle blows away the water droplets remaining at the bottom of the camera protective cover, that is, removes the water droplets at the bottom of the camera protective cover, avoids the water droplets at the bottom of the camera protective cover blocking the line of sight of the camera body, and ensures that the monitoring equipment can maintain a good monitoring state.

[0005] However, the above patent still has the following disadvantages: 1. The above patent uses high-pressure gas to blow away water droplets at the bottom of the camera protective cover to avoid affecting the imaging effect. However, in actual use, since the environment is usually mixed with dust or dirt, if the water droplets remaining on the camera protective cover are mixed with the dust, it is easy for the dust to adhere to the surface after the water dries. If it is not handled, it is easy to affect the imaging effect.

[0006] 2. During use, if there is a temperature difference between the inside and outside of the camera cover in cold weather, fogging is likely to occur on the inside of the camera cover, and the above patent cannot clean the inside, affecting the image quality.

[0007] 3. During use, if the temperature is too extreme, overheating or overcooling can easily cause the camera body to malfunction and affect the monitoring effect, and the camera cover is also prone to rupture due to thermal expansion and contraction caused by extreme temperatures.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0031] like Figure 1-8 As shown, a monitoring and security equipment for a factory includes a support 10, a shell 11 is rotatably connected to the bottom of the support 10, a mounting plate 21 is fixedly connected inside the shell 11, a camera body 39 is fixedly connected to the bottom of the mounting plate 21, a rotating ring 18 is rotatably connected to the bottom side of the mounting plate 21, a glass cover 16 for covering the camera body 39 is fixedly connected to the bottom of the rotating ring 18, a mounting ring 14 is connected to the bottom of the shell 11, the mounting ring 14 and the glass cover 16 rotate relative to each other, a scraper 15 is fixedly connected to the bottom side of the mounting ring 14, the scraper 15 is tightly fitted to the surface of the glass cover 16, and a plurality of ventilation holes 42 are evenly distributed in the scraper 15.

[0032] By providing a rotatable glass cover 16, the scraper 15 can scrape off the water stains when there are water stains on the surface of the glass cover 16, thereby ensuring the monitoring display quality. The surface of the glass cover 16 is hard and wear-resistant, which effectively prevents the wear and scratches on the surface of the glass cover 16 from affecting the camera effect. By providing the ventilation holes 42, ventilation can be facilitated to prevent the water stains on the surface of the glass cover 16 covered by the scraper 15 from being difficult to evaporate.

[0033] like Figure 1-8 As shown, an acrylic cover 17 located in the glass cover 16 is fixedly connected to the bottom of the rotating ring 18, and a gap is left between the glass cover 16 and the acrylic cover 17. A liquid injection ring groove 20 rotatably connected to the rotating ring 18 is arranged on the bottom side of the mounting plate 21. Two liquid pipes 22 are symmetrically distributed and fixedly connected to the mounting plate 21. Each liquid pipe 22 is connected to the liquid injection ring groove 20. A plurality of connecting holes 19 are evenly distributed in the circumferential direction in the rotating ring 18. Each connecting hole 19 is connected to the liquid injection ring groove 20 and the gap between the glass cover 16 and the acrylic cover 17. Two ends of the two liquid pipes 22 close to each other are connected to a heater 23 and a refrigerator 24 respectively. A liquid pump 25 is connected between the heater 23 and the refrigerator 24. The gap between the glass cover 16 and the acrylic cover 17 and the liquid injection ring groove 20 are filled with a transparent liquid, preferably a transparent oil to avoid the growth of mildew or microorganisms.

[0034] By filling the space between the glass cover 16 and the acrylic cover 17 with a transparent liquid, circulating the liquid, and adjusting the temperature of the liquid by using the heater 23 or the refrigerator 24, in cold weather, the liquid is heated to heat up the acrylic cover 17, thereby avoiding fogging of the inner wall of the acrylic cover 17, and effectively avoiding the glass cover 16 from being broken due to thermal expansion and contraction caused by too low a temperature, and maintaining the internal temperature of the device, the camera body 39 is at a suitable working temperature. Similarly, in hot weather, the internal temperature of the device can be kept suitable to avoid thermal expansion and contraction.

[0035] like Figure 1-8 As shown, a wheel frame 26 is slidably connected in the mounting plate 21, a wheel axle 27 is rotatably connected in the wheel frame 26, a first driving gear 28 and a second driving gear 45 are fixedly connected at the upper and lower ends of the wheel axle 27, respectively, a driven gear 37 is fixedly connected to the end of the support 10 extending into the housing 11, and the driven gear 37 can be meshed and connected with the first driving gear 28, an end cover 38 is fixedly connected to the bottom end of the support 10, a driven gear ring 36 is fixedly connected to the inner side of the rotating ring 18, and the driven gear ring 36 can be meshed and connected with the second driving gear 45, and a gear sleeved on the wheel axle 27 is fixedly connected at a corresponding position of the wheel frame 26 on the mounting plate 21. The outer worm gear seat 35 and the wheel shaft 27 are fixedly connected with a worm wheel 30 at a position between the worm gear seat 35 and the mounting plate 21. Two worm seats 32 are fixedly connected to the side of the mounting plate 21 away from the worm gear seat 35. A worm 31 is rotatably connected between the two worm seats 32. The worm 31 is meshingly connected to the worm wheel 30 for transmission connection. One end of the worm 31 extending out of the worm seat 32 is transmission-connected to a motor 33. Two electric push rods 34 are connected between the wheel frame 26 and the mounting plate 21. Two locking tooth blocks 29 are fixedly connected to the upper and lower ends of the wheel frame 26, respectively, and the two locking tooth blocks 29 can respectively mesh with the driven gear 37 and the driven gear ring 36.

[0036] By setting the first driving gear 28, the second driving gear 45, the driven gear ring 36 and the driven gear 37, the camera body 39 can be driven to rotate to change the monitoring position, and the glass cover 16 can be controlled to rotate to scrape off water stains. The wheel frame 26 can be controlled to move up and down by the electric push rod 34 to achieve switching. During the switching process, the locking tooth block 29 can be used to engage the driven gear 37 or the driven gear ring 36 to prevent the equipment from shaking.

[0037] like Figure 1-8 As shown, a plurality of through heat dissipation openings 12 are provided on the outer side of the shell 11, a plurality of spaced blades 13 are fixedly connected in each heat dissipation opening 12, and each blade 13 is arranged at an angle. An external temperature sensor 41 is fixedly connected to the outer side of the shell 11, an internal temperature sensor 40 is fixedly connected to the outer side of the camera body 39, a controller 44 is fixedly connected to the mounting plate 21, and a through wiring hole 43 is provided in the support 10.

[0038] By providing the heat dissipation port 12, ventilation and heat dissipation effects can be achieved, and the temperature of the device can be easily adjusted. By providing the external temperature sensor 41 and the internal temperature sensor 40, the temperature difference between the inside and outside of the device can be detected, so as to accurately adjust the temperature of the transparent liquid.

[0039] In this embodiment, initially, the present invention is installed at a location where monitoring is required, and various power supply and control cables are connected to the external control system through the wiring hole 43. At this time, the electric push rod 34 is in an extended state, and the locking tooth block 29 at the bottom is engaged and locked with the driven gear ring 36, and the first drive gear 28 is engaged with the driven gear 37. At this time, the operator can start the motor 33 through the control system, and the first drive gear 28 is driven to rotate through the meshing transmission of the worm 31 and the worm wheel 30, so that the housing 11 rotates under the support 10, thereby achieving the effect of adjusting the monitoring direction.

[0040] During the monitoring process, if it rains, rainwater attached to the surface of the glass cover 16 will affect the imaging quality. At this time, the control system controls the electric push rod 34 to retract, so that the first drive gear 28 disengages from the driven gear 37 and the locking tooth block 29 engages and locks with the driven gear 37. At the same time, the locking tooth block 29 below disengages from the engagement with the driven gear ring 36 and enables the second drive gear 45 to engage with the driven gear ring 36. At this time, the motor 33 drives the second drive gear 45 through the worm 31 and the worm wheel 30 to drive the rotating ring 18 and the glass cover 16 to rotate. The glass cover 16 is continuously scraped with the scraper 15 to remove the residual moisture on the surface of the glass cover 16. Compared with the method of blowing out water stains, no dust will remain to prevent the glass cover 16 from being contaminated and affecting the imaging quality.

[0041] During the monitoring process, the temperature difference between the inside and outside of the device is detected by the external temperature sensor 41 and the internal temperature sensor 40. In a cold environment, the outside temperature is too low, and the inside of the device will emit heat when the camera body 39 is working, so there will be a temperature difference between the inside and outside of the device. If the internal warm air encounters the colder glass cover 16, it is easy to fog on the surface of the glass cover 16, affecting the imaging quality.

[0042] At this time, the liquid pump 25 is started to circulate the transparent liquid between the glass cover 16 and the acrylic cover 17, and the temperature difference detected by the internal temperature sensor 40 and the external temperature sensor 41 controls the heater 23 to heat the transparent liquid to a suitable temperature, so that the temperature of the acrylic cover 17 and the glass cover 16 is increased, and fogging is not likely to occur. In addition, the glass cover 16 is effectively prevented from cracking due to the heat barrier and cold shrinkage, thereby ensuring the practical life and being suitable for use in various harsh environments.

[0043] Similarly, in a high temperature environment, the transparent liquid can also be cooled by the refrigerator 24, thereby cooling the working environment of the camera body 39 to avoid malfunction of the camera body 39 at high temperature and to avoid cracking of the glass cover 16 due to thermal expansion and contraction.

[0044] During the cooling process, the refrigerator 24 itself needs to dissipate heat to satisfy the heat exchange. At this time, the external airflow is used to dissipate heat through the heat dissipation port 12 to avoid heat accumulation inside the device. By setting the inclined blades 13, it can effectively prevent rainwater from entering the device and avoid short circuit failure inside the device.

[0045] The above-mentioned heater 23, refrigerator 24, liquid pump 25, motor 33, camera body 39, controller 44, etc. are mature existing technologies and will not be described in detail herein.

[0046] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0047] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0048] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be within the scope of protection of the claims attached to the present application.
