Detailed implementation mode

[0026] The following describes in detail a distributed remote radiation environment monitoring device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0027] As Figure 1 - Figure 4 shown, an embodiment of the present utility model provides a distributed remote radiation environment monitoring device, including a base 1 with an inner cavity 11 opened at the top, a water isolation plate 12 provided at the top position of the side wall of the inner cavity 11, a central control component 4 provided inside the inner cavity 11, a bracket for installation and fixation provided at the bottom of the base 1, and the bracket is fixed at a preset node position through cooperation with bolts; a rotating seat 2, having a round cover-like structure and rotatably connected with the base 1, an annular tooth 23 is provided at the bottom end position on the inner side wall of the cylindrical structure at the lower edge of the bottom of the rotating seat 2, a radiation monitor 3 is provided at the top of the rotating seat 2, and the radiation monitor 3 is electrically connected to the central control component 4.

[0028] By setting the central control component 4 to control the rotation of the rotating seat 2, the monitoring orientation of the radiation monitor 3 is adjusted, thereby expanding the monitoring range and facilitating the positioning of the radiation source; through the setting of the water isolation plate 12, rainwater is prevented from entering the inner cavity 11 and affecting the normal operation of the internal electronic components of the device.

[0029] One end of the electrical connection between the central control component 4 and the radiation monitor 3 close to the radiation monitor 3 is connected through a floating joint.

[0030] With this setting, it is ensured that during the rotation of the rotating seat 2 driving the radiation monitor 3, the central control component 4 always maintains a stable electrical connection with the radiation monitor 3.

[0031] As Figure 2 shown, the rotating seat 2 includes a mounting seat 21 and an annular groove 22 opened at the edge position of the bottom of the mounting seat 21 for sliding connection with the water isolation plate 12.

[0032] By inserting the protruding water isolation plate 12 into the annular groove 22, the rotation fit of the base 1 to the rotating seat 2 is realized, and the stability of their relative rotation is ensured. During the rotation process, the outer side wall of the water isolation plate 12 slides with the inner part of the annular groove 22.

[0033] As Figure 1 shown, the bottom of the radiation monitor 3 is fixedly connected to the center position of the top of the mounting seat 21 through a mounting plate 31. The mounting plate 31 and the rotating seat 2 are detachably connected, and the connection part between them is sealed. They are fixedly connected by bolts. A monitoring probe 32 is provided on one side of the radiation monitor 3.

[0034] As Figure 4 shown, it also includes a rotating shaft 5, a gear 6, a worm gear 7, a motor 8, and a worm 9. A cavity for installing the worm gear 7, the motor 8, and the worm 9 is opened inside the base 1; the rotating shaft 5 is vertically rotationally connected to the bottom wall of the inner cavity 11, and the gear 6 is fixedly connected to the shaft body of the rotating shaft 5 located inside the inner cavity 11. The gear 6 is engaged and connected with the annular teeth 23; the motor 8 is relatively fixed to the base 1, the output end of the motor 8 is fixedly connected to one end of the worm 9, and the end of the worm 9 away from the motor 8 is rotationally connected to the side wall of the cavity. The end of the shaft body of the bottom end of the rotating shaft 5 located inside the cavity is fixedly connected to the worm gear 7, and the worm gear 7 is in transmission connection with the worm 9. Among them, the motor 8 uses a GA20Y-130 micro DC reduction motor, which has the characteristics of small volume and light weight, and can meet the driving work requirements.

[0035] The motor 8 drives the worm 9 to rotate, and then through the transmission connection between the worm 9 and the worm gear 7, the rotating shaft 5 is driven to rotate. Finally, through the meshing connection between the gear 6 and the annular teeth 23, the rotation of the rotating seat 2 is driven.

[0036] Among them, both the motor 8 and the central control component 4 are connected to an external power supply, and the motor 8 is electrically connected to the central control component 4. The central control component 4 includes a machine control module for controlling the forward and reverse rotation and speed of the motor 8, a switch module for controlling the opening and closing of the radiation monitor 3, a receiving module for receiving the detection data of the radiation monitor 3, a data processing module for processing the received data, a signal sending module for remotely transmitting data signals, and a signal amplifier for enhancing the signal strength of the transmitted signal.

[0037] When the technical solution provided by the present utility model is actually used, the whole device is installed at the node position where the radiation intensity needs to be monitored according to the layout network. During the monitoring process, the central control component 4 controls the motor 8 to rotate periodically forward and backward. The motor 8 drives the worm 9 to rotate, and then, in cooperation with the transmission connection between the worm 9 and the worm gear 7, drives the rotating shaft 5 to rotate. Finally, in cooperation with the meshing connection between the gear 6 and the annular tooth 23, the rotation of the rotating seat 2 is driven. Through the rotation of the rotating seat 2, the monitoring range of the monitoring probe 32 on the radiation detector 3 is periodically turned, thereby expanding the monitoring range. When abnormal radiation intensity is detected, the data processing module compares the radiation intensity magnitudes at different orientation angles of the monitoring probe 32, and controls the motor 8 to make fine adjustments until the monitoring probe 32 faces the direction with the maximum detected value. At the same time, in cooperation with the orientations of the monitoring probes 32 on the radiation detectors 3 at other nodes on the layout network, the position of the radiation source can be quickly determined according to the intersection position of the extension lines of the orientations of multiple monitoring probes 32.

[0038] The present utility model covers any alternatives, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
