Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a video monitoring device for drifting ice in a large water delivery channel. Background Art

[0002] Drift ice is a common natural phenomenon in winter. As the temperature drops below freezing, a thick layer of ice forms on the water surface. Under the impact of the water flow, the ice breaks and flows down along the water flow, impacting the river banks and dams along the way, causing great harm. In the management of large-scale water channels, in order to detect and avoid the hazards caused by drift ice as early as possible, video surveillance equipment is usually installed along the water channel to facilitate back-end staff to monitor at any time.

[0003] The monitoring equipment currently used to monitor drifting ice along large water channels is mostly similar in overall structure. It is based on a steel pole with a pan-tilt camera installed on the top of the pole, which can collect image information of the water channel from multiple positions and angles. However, there are some functional deficiencies in actual use and there is room for improvement. For example, when the water flow is slow, the difference between the ice surface and the water surface is not obvious when viewed from the video angle. In addition, the backstage staff can only detect the ice surface after it is obviously formed. There is a certain lag in monitoring, and it is impossible to detect the early stage of water surface freezing and make advance plans. It does not have the function of monitoring water surface temperature.

[0004] Now, a new video monitoring device for drift ice in large water delivery channels is proposed to solve the above problems. Utility Model Content

[0014] Preferably, the position and size of the limiting ribs and the limiting ribs correspond to each other, and the top end of the electric cylinder is connected to the bottom end of the upper cylinder rod.

[0015] Compared with the existing technology, the beneficial effects of the present invention are: the video monitoring device for drift ice in large water channels not only realizes the function of monitoring water surface temperature, but also realizes the function of protecting the camera and the function of adjusting the camera height;

The antenna reserved eyes reserve a notch for the camera antenna, and the longitudinal support rods, fixing ring sleeves, support rod mounting brackets, positioning rings and fixing screw rings facilitate the installation and removal of the steel cover, thereby achieving the function of protecting the camera;

[0018] (3) By setting the limiting grooves, inner cavity, limiting ribs and electric cylinders, when the monitoring range needs to be expanded according to the needs of the monitoring section, the electric cylinder extends upward to push the upper cylinder rod upward along the inner cavity. The limiting grooves on the outside of the upper cylinder rod and the limiting ribs inside the inner cavity cooperate with each other, which can make the upper cylinder rod slide up and down more stably and smoothly. When the height of the upper cylinder rod changes, the height of the camera also changes accordingly, and the monitoring range changes immediately, realizing the function of adjustable camera height.

[0027] The right side of the oblique support frame 4 is connected to the left side of the main barrel rod 1. The inner and outer diameters of the side extension frame 3 and the transverse extension frame 5 are the same. The infrared temperature sensor 8, the sound sensor 9, and the signal wiring 10 are electrically connected. The signal wiring 10 and the control box 25 are connected. The horizontal center lines of the side extension frame 3 and the transverse extension frame 5 coincide with each other. The transverse extension frame 5 and the connecting flange ring 6 are connected. By monitoring the water surface temperature, drift ice can be detected in time, facilitating advance planning.

[0028] Specifically, if Figure 1 and Figure 3 As shown, the infrared temperature sensor 8 is aimed at the water surface to measure the water surface temperature in real time. When the temperature is below the freezing point, the background monitoring personnel can intuitively discover it through the temperature data and make plans in advance.

[0030] Specifically, if Figure 1 and Figure 2 As shown, the steel cover 13 can play a shielding role to prevent the pan-tilt camera 12 from being damaged by impact, and at the same time can provide shade and rain protection to extend its service life.

[0033] Working principle: When the present invention is in use, first, the pan-tilt camera 12 collects the water surface image of the corresponding section of the water channel in real time, and feeds it back to the management background in real time through the signal transmission antenna 24 on the control box 25. The infrared temperature sensor 8 is aimed at the water surface and measures the temperature of the water surface in real time. When the temperature is below the freezing point, the background monitoring personnel can intuitively discover it through the temperature data and make plans in advance. The sound sensor 9 can capture the sound of ice cubes hitting the edge of the channel when drifting ice occurs, and provide further feedback. The side extension frame 3, the oblique support frame 4, the horizontal extension frame 5, and the connecting flange ring 6 provide physical support for the installation and fixation of the infrared temperature sensor 8 and the sound sensor 9. The signal wiring 10 is used for the real-time transmission of the monitoring signal. In extreme weather conditions such as hail in summer, the steel cover 13 can act as a shield to prevent damage to the pan / tilt camera 12 caused by impact, while also providing shade and rain protection, extending its service life. The antenna eye 14 reserves a slot for the camera's antenna. The longitudinal support rod 15, fixing ring sleeve 16, support rod mounting bracket 17, positioning ring 18, and fixing screw ring 19 facilitate the installation and removal of the steel cover 13. When the monitoring range needs to be expanded according to the needs of the monitoring section, the electric cylinder 23 extends upward, pushing the upper cylinder rod 11 upward along the inner cavity 21. The limiting ribs 20 on the outside of the upper cylinder rod 11 and the limiting ribs 22 on the inside of the inner cavity 21 cooperate with each other, allowing the upper cylinder rod 11 to slide up and down more stably and smoothly. As the height of the upper cylinder rod 11 changes, the height of the camera also changes, and the monitoring range changes accordingly.
