[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in, Figure 1 A schematic diagram of the overall structure of the cable tunnel comprehensive online monitoring device provided by the utility model; Figure 2 A partial schematic diagram of the comprehensive online monitoring device for cable tunnels provided by the utility model; Figure 3 A partial disassembled diagram of the cable tunnel comprehensive online monitoring device provided by the utility model; Figure 4 This is a partial schematic diagram of the connecting plate provided by the utility model.

[0023] In the specific implementation process, Figure 1-Figure 4 As shown, the cable tunnel integrated online monitoring device comprises a control body 1, a plurality of monitoring bodies 2 and a connecting plate 3, wherein the plurality of monitoring bodies 2 are connected to the connecting plate 3 via a plurality of connecting components;

[0024] The connecting assembly includes a connecting block 6 and two limiting groups, one side of the connecting block 6 is fixedly connected to one side of the monitoring body 2, a mounting groove 8 is provided on the connecting plate 3, a side of the connecting block 6 away from the detection body is movably arranged in the mounting groove 8, opposite sides of the connecting plate 3 are fixedly connected with fixed blocks 13, the two fixed blocks 13 are respectively movably arranged in two movable grooves 10 provided on the connecting plate 3, the two limiting groups are respectively used to limit the positions of the two fixed blocks 13, the limiting group includes a limiting block 9 and a spring 7, one side of the limiting block 9 extends to the inside of the connecting plate 3, one end of the limiting block 9 close to the connecting plate 3 is fixedly connected to one end of the spring 7, one end of the spring 7 away from the limiting block 9 is fixedly connected to the inner side wall of the connecting plate 3, and the edge of the side of the limiting block 9 away from the spring 7 is set in an arc shape;

[0025] In the specific implementation process, when the monitoring body 2 needs to be removed from the connecting plate 3, the limiting block 9 can be first pushed toward the inside of the connecting plate 3. In this process, the pushing of the limiting plate compresses the spring 7, and at the same time makes the fixing block 13 set on the opposite side of the connecting plate 3 lose its fixing force, so that the connecting plate 3 can be taken out from the inside of the mounting groove 8 on the connecting plate 3;

[0026] When installing the monitoring body 2, the connecting block 6 can be moved directly into the installation groove 8. During this process, the connecting block 6 will contact the arc-shaped side wall of the limiting block 9, and the limiting block 9 will enter the inside of the connecting block 6 through the connecting block 6 until the connecting block 6 completely passes through the limiting block 9. Then, the limiting block 9 pops out due to the elastic force of the spring 7, and the fixing of the connecting block 6 is completed, and finally the installation of the monitoring body 2 is completed;

[0027] The control body 1 is connected to one of the detection bodies via a first cable 5, and the plurality of monitoring bodies 2 are connected via a second cable 4. A box door 11 is installed on one side of the control body 1;

[0028] Among them, the monitoring subject 2 mentioned above is: DENOD-GD200-TH explosion-proof temperature and humidity detector, which has the advantages of fast response time and high detection accuracy;

[0029] The control subject 1 is specifically: LORA wireless data collector, which is a low-power, long-distance, low-rate wireless communication technology. It uses spread spectrum modulation technology to transmit data, can provide stable data transmission over a long distance, and has the characteristics of low power consumption;

[0030] A reset block 12 is fixedly connected to the upper end of the limit block 9 , and the reset block 12 is movably arranged inside a reset groove arranged on the connecting plate 3 . The reset block 12 is arranged to facilitate adjustment of the position of the limit block 9 .

[0031] The working principle of the utility model is as follows: when the monitoring body 2 needs to be removed from the connecting plate 3, the limiting block 9 can be pushed toward the inside of the connecting plate 3. In this process, the pushing of the limiting plate compresses the spring 7, and at the same time makes the fixing block 13 set on the opposite side of the connecting plate 3 lose its fixing force, so that the connecting plate 3 can be taken out from the inside of the mounting groove 8 on the connecting plate 3;

[0032] When installing the monitoring body 2, the connecting block 6 can be moved directly into the installation groove 8. During this process, the connecting block 6 will contact the arc-shaped side wall of the limiting block 9, and the limiting block 9 will be squeezed by the connecting block 6 to enter the interior of the connecting block 6 until the connecting block 6 completely passes through the limiting block 9. Then, the limiting block 9 pops out due to the elastic force of the spring 7, completing the fixation of the connecting block 6 and finally completing the installation of the monitoring body 2.

[0033] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
