Description

Technical Field

[0001] This utility model relates to a video surveillance device, and more specifically, to a track-mounted monitoring device for online charging. Background Technology

[0002] Because track-mounted monitoring vehicles need to move long distances on the track, it is difficult to power them with power cables. Therefore, batteries are usually used to power them. However, existing track-mounted monitoring vehicles require manual battery replacement when the batteries are depleted. The replaced batteries need to be taken to charging equipment. This replacement method requires workers to repeatedly move and disassemble batteries, which is labor-intensive. Furthermore, the monitoring system loses power during battery replacement and requires waiting for it to restart, resulting in intermittent monitoring. Additionally, the track-mounted monitoring vehicles are located at high altitudes, posing certain safety hazards to workers when replacing batteries. Utility Model Content

[0019] See Figure 1-4 As shown, this utility model discloses an online charging track-type monitoring device, including a track 1 and a monitoring unit that cooperates with the track 1. The monitoring unit includes a housing 2, a camera 3 at the bottom of the housing 2, and a battery 4 inside the housing 2. The housing 2 is equipped with a traveling component 5 that cooperates with the track 1. The track is suspended from the ceiling, beams, or other building structures by a hanger.

[0020] The enclosure also contains modules such as antennas, wireless transmission modules, control terminals, and switches for transmitting camera data and controlling the movement of the walking components. Management personnel can remotely control the device wirelessly from an external monitoring room via computers or other control terminals. These are common knowledge to those skilled in the art and will not be elaborated upon here.

[0021] A charging brush plate 6 connected to the battery 4 is located on the back of the housing 2. A charging brush head 7, which mates with the charging brush plate 6 and is connected to an external power source, is located at the rear of one end of the track 1. A limit switch 8, which mates with the housing 2, is located above the charging brush head 7. When charging is required, the housing moves to the position where it mates with the limit switch via the walking assembly, so that the charging brush head contacts the charging brush plate for charging. This allows the charging process to be carried out online without the need to disassemble or replace the battery. The monitoring system remains uninterrupted, ensuring continuous and stable monitoring without restart intervals. It also effectively reduces the workload of workers and avoids the risks associated with battery replacement.

[0022] The charging brush head can be installed via a bracket connected to the track, or via a building wall or external bracket or platform next to the track. These are options that can be chosen by those skilled in the art based on the specific installation environment.

[0023] The charging brush plate and charging brush head are existing technology charging carbon brushes, and their specific structure and connection method are common knowledge to those skilled in the art, and will not be described in detail here.

[0024] In this embodiment, preferably, mounting sleeves 9 are detachably provided at both ends of the track 1 along its length. A reciprocating positioning plate 10 is provided on one side of the mounting sleeve 9, and a sensor 11 that cooperates with the reciprocating positioning plate 10 is provided on the housing 2. A suspension 12 is provided on the mounting sleeve 9, and a buffer 13 that cooperates with the housing 2 is provided on the suspension 12. The reciprocating positioning plate and the sensor cooperate to control the walking component to decelerate and steer, and the buffer is set to prevent the housing from colliding with the reciprocating positioning plate. The mounting sleeve is composed of two C-shaped plates, and end plates for locking screws are provided at both ends of the C-shaped plates. The reciprocating positioning plate and the suspension are fixed to the end plates by screws.

[0025] More preferably, the suspension 12 is positioned near the charging brush plate 6, and an L-shaped bracket 14 is provided on one end of the suspension 12, with the charging brush head 7 mounted on the L-shaped bracket 14. With this structure, the charging brush head is mounted on the suspension, and if the installation position needs to be changed during use, it can be adjusted directly by moving the mounting sleeve and the position of the suspension.

[0026] In this embodiment, the walking assembly 5 includes a drive motor 5a housed within a housing 2. A drive wheel 5b and an upper driven wheel 5c are mounted on the housing 2 via bearings, and the drive wheel 5b and upper driven wheel 5c engage with the upper surface of the track 1. The output shaft of the drive motor 5a is connected to the drive wheel 5b via a reduction gearbox 5d. A transmission assembly 15 is located between the drive wheel 5b and the upper driven wheel 5c. A self-tensioning wheel assembly 16 is mounted on the housing 2 and engages with the lower surface of the track 1. The self-tensioning wheel assembly, in conjunction with the drive wheel and upper driven wheel located above the track, clamps the track, ensuring that derailment does not occur during movement.

[0027] Preferably, the transmission assembly 15 includes a transmission belt 15a disposed between the driving wheel 5b and the upper driven wheel 5c. Both the driving wheel 5b and the upper driven wheel 5c have annular grooves 15b that mate with the transmission belt 15a. A mounting plate 15c is disposed on the housing 2 between the driving wheel 5b and the upper driven wheel 5c. An idler wheel 15d is connected to the upper end of the mounting plate 15c via a shaft. An adjusting elongated hole 15e is provided on the mounting plate 15c. Two fastening screws 15f, mate with the adjusting elongated hole 15e, are vertically spaced along the housing 2. The idler wheel presses the transmission belt, ensuring a tight fit between both ends of the transmission belt and the driving wheel and the upper driven wheel for transmission, thus ensuring the moving efficiency of the walking assembly. When the annular groove wears down, causing its inner diameter to decrease or the transmission belt to become thinner, the pressure between the idler wheel and the transmission belt is adjusted by the adjusting elongated hole to keep the transmission belt taut and ensure transmission continues.

[0028] More preferably, the self-tensioning wheel assembly 16 includes two bearing seats 16a symmetrically arranged on the housing 2. A crank arm bracket 16b is hinged to each bearing seat 16a, and a lower driven wheel 16c is mounted on the crank arm bracket 16b via bearings. A vertical adjusting screw 16d is provided on the housing 2 above the free end of the crank arm bracket 16b, and the vertical adjusting screw 16d is connected to the free end of the crank arm bracket 16b via a spring 16e. The vertical adjusting screw and spring pull the end of the crank arm bracket upwards, causing the lower driven wheel to press against the lower surface of the track. Adjusting the height of the vertical adjusting screw adjusts the pressure between the lower driven wheel and the lower surface of the track, adapting to tracks of different thicknesses and ensuring that the pressure between the upper and lower wheel assemblies is within a suitable range, preventing derailment while maintaining movement.

[0029] In this embodiment, an RFID chip is provided on one outer wall of the track 1, and an RFID sensor 17 for reading the RFID chip is provided on the housing 2. The RFID chips are evenly distributed along the track. The position of the monitoring equipment is determined by reading the RFID chips on the track by the RFID sensor. The data reading method and positioning algorithm between the RFID sensor and the RFID chip are existing technologies and will not be described in detail here.

[0030] During operation, the drive motor propels the housing back and forth along the track between two reciprocating positioning plates. A camera monitors the area below the track in real time and transmits the data to a terminal in the external monitoring room. When the battery level drops to the warning threshold, the housing moves along the track towards the charging brush head. When the housing contacts the limit switch, the drive motor shuts off, stopping the movement. At this point, the charging brush plate engages with the charging brush head to begin charging.

[0031] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
