[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Embodiment 1:

[0041] In order to solve the problem that the existing monitoring and recording equipment often lacks protective measures when in use, resulting in the possibility that the wire ends of the external wires of the monitoring and recording equipment may be damaged during use, which is not conducive to use, the present embodiment discloses the following technical solutions, specifically as follows: Figure 1-Figure 8 As shown, one set of sliding racks 122 is fixedly connected to the protective door 13, and another set of sliding racks 122 is fixedly connected to the sliding frame 14. One end of the transmission gear 121 is fixedly connected to the limiting block 123. The interior of the protective shell 1 is also fixedly connected to a spring rod 124, and one end of the spring rod 124 is fixedly connected to the limiting block 125. The limiting block 123 and the limiting block 125 are slidably matched. The interior of the protective shell 1 is also fixedly connected to an electromagnet 126, and the electromagnet 126 is electrically connected to the motor 12. The top of the sliding frame 14 is rotatably connected to a rotating frame 141, and the sliding frame 14 and the rotating frame 141 are provided with a wire release groove 142. The sliding frame 1 4 is also provided with a card slot 143, and the inner side of the card slot 143 is fixedly connected with a return spring 144, one end of the return spring 144 is fixedly connected with an ejection block 145, the outer side of the sliding frame 14 is threadedly connected with a screw 146, and the bottom of the rotating frame 141 is fixedly connected with a card block 147, and the card block 147 is slidably matched with the card slot 143, and the card block 147 is matched with the screw 146. When the device is used, the power supply of the motor 12 can be turned on at this time, and the electromagnet 126 can be energized after the motor 12 is energized, and the electromagnet 126 can produce an adsorption effect on the limit block 2 125, so that the limit block 2 125 is separated from the limit block 123, and the motor 12 can be started at this time. The motor 12 drives the transmission gear 121 to rotate, thereby moving the two groups of sliding racks 122. One group of sliding racks 122 drives the protective door 13 to move, thereby opening one side of the protective shell 1. The other group of sliding racks 122 moves, thereby moving the protective door 13 to the opening on one side of the protective shell 1. When it is necessary to plug the external cable into the monitoring device body 2, the screw 146 at one end of the sliding frame 14 can be rotated. The screw 146 rotates to make the block 147 lose its force. At this time, under the action of the reset spring 144 and the ejection block 145, the rotating frame 141 rotates, and the cable plug can be plugged into the monitoring device body 2, and the cable plug can be plugged into the monitoring device body 2. The wire is placed on the wire placing groove 142, and then the rotating frame 141 is closed, so that the rotating frame 141 is fitted with the sliding frame 14, and the screw 146 can be rotated in the opposite direction at this time to fix the block 147, so as to protect the external patch cord. When the monitoring device body 2 is not in use, the motor 12 can be started in the opposite direction to close the protective door 13, and then the electric push rod 11 can be started. The electric push rod 11 drives the placement frame 111 to move, so that the monitoring device body 2 moves to the inside of the protective shell 1, and protects the monitoring device body 2, thereby realizing the protection effect on the monitoring device body 2 and the patch cord of the monitoring device body 2, which is convenient for use.

[0042] At the same time, in order to solve the problem that the storage board 22 inside the existing monitoring and recording equipment is often connected through a complex connection mechanism, when the user needs to take out and record data, it is not convenient to take it out quickly, which affects the work efficiency, the present embodiment also discloses the following scheme: a placement port 21 is opened on one side of the protective shell 1, and a knob 211 is rotatably connected to one side of the protective shell 1. One end of the knob 211 extends to the inside of the protective shell 1 and is fixedly connected to a bevel gear 1 212, and one side of the bevel gear 1 212 is meshedly connected to a bevel gear 213, and the bevel gear 213 is rotatably connected to the inside of the protective shell 1. The bevel gear 213 is rotatably connected to the inside of the protective shell 1. A screw rod 214 is fixedly connected to one side of the wheel 213, and a baffle plate 215 is threadedly connected to the outer side of the screw rod 214, and the baffle plate 215 is slidably connected to the inside of the placement port 21, and a storage plate 22 is detachably provided inside the placement port 21. A rotating plate 222 is also rotatably connected to the inside of the protective shell 1, and a spring rod 223 is fixedly connected to one side of the rotating plate 222, and one end of the spring rod 223 is fixedly connected to the inside of the protective shell 1, the rotating plate 222 matches the baffle plate 215, and a protrusion 224 is fixedly connected to one end of the rotating plate 222, and an L-shaped clamping rod 221 is fixedly connected to one side of the storage plate 22, The inside of the protective shell 1 is also fixedly connected with a clamp 225, and the L-shaped clamp rod 221 matches the clamp 225. The L-shaped clamp rod 221 is composed of elastic material, and the protrusion 224 slides with the clamp 225. When the monitoring device body 2 records the voltage and related parameters of the shielding door, when the recorded data needs to be exported, the knob 211 located on one side of the protective shell 1 can be rotated, and the knob 211 drives the bevel gear 1 212 to rotate, thereby rotating the bevel gear 213, and the bevel gear 213 drives the screw 214 to rotate, thereby moving the baffle 215, and the movement of the baffle 215 can open the placement port 21, and When the baffle 215 moves, it will contact one end of the rotating plate 222, thereby causing the rotating plate 222 to rotate. The rotating plate 222 drives the protrusion 224 to move, thereby causing the L-shaped clamping rod 221 engaged in the clamp 225 to be ejected. At this time, the storage plate 22 loses its clamping force, thereby allowing the storage plate 22 to be taken out from the inside of the placement port 21. When installation operation is required, the storage plate 22 can be placed in place and the knob 211 can be rotated in the opposite direction to re-fix the storage plate 22 inside the protective shell 1, thereby making it convenient for the staff to take out the storage plate 22 and record, thereby improving the use effect.

[0043] Embodiment 2:

[0044] In order to solve the problem that the existing monitoring and recording equipment is not convenient for heat dissipation when in use, when the weather is hot, the working efficiency of the whole device will decrease, which is not conducive to use, this embodiment discloses the following technical solutions, specifically as follows: Figure 2 , Fig. 9 and Fig.10 As shown, a vent 1 23 is provided on the top of the protective shell 1, and a motor 231 is fixedly connected to the inside of the vent 1 23, a reciprocating screw rod 1 232 is fixedly connected to the output end of the motor 231, and a fan module 233 is threadedly connected to the outer side of the reciprocating screw rod 1 232, and the fan module 233 is slidably connected to the inside of the vent 1 23, and a vent 24 is also provided on one side of the protective shell 1, one end of the reciprocating screw rod 1 232 is fixedly connected to a bevel gear 3 234, one side of the bevel gear 3 234 is meshedly connected to a bevel gear 4 235, one side of the bevel gear 4 235 is fixedly connected to a reciprocating screw rod 236, the outer side of the reciprocating screw rod 236 is threadedly connected to a cleaning rod 237, a dust net 241 is fixedly connected to the inner side of the vent 24, a collecting box 242 is detachably provided on one side of the protective shell 1, and the collecting box 242 is located below the dust net 241, and the cleaning rod 237 is slidably connected to the outer side of the dust net 241, When it is necessary to cool the monitoring device body 2, the motor 231 can be started. The motor 231 drives the reciprocating screw 1 232 to rotate, thereby causing the fan module 233 to reciprocate inside the protective shell 1, thereby increasing the air flow rate inside the device, and the setting of a group of fan modules 233 can avoid the generation of additional heat. When the reciprocating screw 1 232 rotates, the bevel gear 3 234 rotates, and the bevel gear 3 234 drives the bevel gear 4 235 to rotate, thereby causing the reciprocating screw 236 to rotate. The reciprocating screw 236 can cause the cleaning rod 237 to reciprocate, and the dust net 241 can be cleaned at this time. The dust after cleaning can fall into the collection box 242. When the collection box 242 needs to be cleaned, the collection box 242 can be pulled out from the inside of the protective shell 1, thereby achieving the effect of efficiently dissipating the heat of the monitoring device body 2 and preventing the vents from being blocked.
