[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a monitoring device for a security monitoring system, including a monitoring shell 1 and a glass 3 installed at the lens end of the monitoring shell 1. A camera, a main board and a communication device are also arranged inside the monitoring shell 1, which are existing and mature technologies and are not described in detail. At the same time, a mounting bracket is also fixed at the lower end of the monitoring shell 1. It should be noted that this device is improved based on the existing monitoring equipment. At the same time, this device is incorporated into the security monitoring system to realize the transmission of video signals, so that security personnel can view the recorded content in real time.

[0024] The lower end of the outer surface of the monitoring housing 1 is located on one side of the glass 3 and is fixed with a fixing box 2 by screws. A partition is fixed on one side of the inside of the fixing box 2. The partition divides the inside of the fixing box 2 from left to right into a gear compartment 10 and a cavity 11 (such as Figure 3 As shown), one side of the inner cavity of the cavity 11 is fixed to the mounting end of the reduction motor 7 by bolts, the output shaft of the reduction motor 7 movably passes through the partition, and the output shaft of the reduction motor 7 is keyed and fixed to the spur gear 12. The two ends of the inner cavity of the cavity 11 are located on one side of the reduction motor 7 and a reciprocating screw 8 is movably inserted therein. One end of the reciprocating screw 8 movably passes through the partition and its end extends into the gear compartment 10. One end of the reciprocating screw 8 is fixedly provided with a spur gear 2 13 meshing with the spur gear 12. The number of teeth of the spur gear 12 is much smaller than that of the spur gear 2 13, thereby achieving the effect of reducing speed and increasing torque.

[0025] A rectangular connecting frame 9 is fixed to one side of the moving part of the reciprocating screw 8, and the side of the connecting frame 9 away from the moving part is fixed to the air jet pipe 5. The fixing box 2 is located on one side of the air jet pipe 5 and is provided with a slot 14. Both sides of the slot 14 extend to the gear compartment 10 and one end of the cavity 11, thereby increasing the moving distance of the connecting frame 9. The connecting frame 9 moves laterally inside the slot 14 and limits the position. A plurality of arrays of air jet nozzles 6 are fixed to the inclined part of the glass 3 on the surface of the air jet pipe 5. The middle part of the air jet pipe 5 is a cavity, and the air jet nozzles 6 are all connected to the cavity in the middle part of the air jet pipe 5. It should be noted that in order to increase the cleaning effect on the surface of the glass 3, the inclination angle of the air jet nozzle 6 is 10-30 degrees.

[0026] Among them, the reciprocating screw 8, the reduction motor 7, the high-pressure tank 21, the air pump 16, and the solenoid valve 18 are all existing and mature technologies, and their structural principles are not repeated here. At the same time, this application directly uses the structural names of the existing devices, and the air pump 16 preferably has a pressure-maintaining function. A pressure relief valve is also provided on the high-pressure tank 21 to prevent the pressure in the tank from being too high.

[0027] The bottom of the inner cavity of the monitoring housing 1 is respectively fixed with a dry ice storage box 15, an air pump 16 and a high-pressure tank 21 (such as Figure 4 As shown in the figure, the interior of the dry ice storage box 15 is filled with dry ice particles in advance, the air pump 16 is connected and fixed to the high-pressure tank 21 through an air pipe, one end of the dry ice storage box 15 is connected to the solenoid valve 18 through a pipe 19, and one end of the high-pressure tank 21 is connected to the solenoid valve 18 through a pipe 20, and the outlet end of the solenoid valve 18 is connected and fixed to the jet pipe 5 through a bellows 4. The above-mentioned pipe 19, pipe 20 and the connection and installation method of the pipe are existing and conventional technologies and will not be described in detail. It should be noted that the one-way valve 17 in the middle of the pipe 19 cuts off the pipe 19, and then the ends of the pipe 19 are respectively fixed to the two sides of the one-way valve 17, so that the dry ice particles flow from the dry ice storage box 15 toward the solenoid valve 18, so as to prevent the high-pressure gas from entering the dry ice storage box 15 and causing the device to be unable to be cleaned and used. It should be noted that one end of the pipe 19 is fixed to the bottom of the inner cavity of the dry ice storage box 15 and is covered by dry ice particles.

[0028] The bellows 4 is configured as a hose and movably penetrates the side wall of the monitoring housing 1 .

[0029] A one-way valve 17 is fixedly provided in the middle of the pipeline 19 for realizing one-way flow of the airflow in the pipeline 19.

[0030] The device can be controlled by the monitoring system via wireless signals or network cables, and the lower end surface of the monitoring housing 1 is provided with heat dissipation holes for heat dissipation.

[0031] Principle and process of this utility model:

[0032] After the device is installed, the air pump 16 is powered on, and the air pump 16 draws the outside air and the air inside the monitoring shell 1 into the high-pressure tank 21 through the heat dissipation holes through the pipeline and gathers to generate pressure. At this time, the solenoid valve 18 is in a closed state, and the pipeline 19, the pipeline 20 and the pipeline are not connected.

[0033] When the glass 3 needs to be cleaned, the reduction motor 7 is energized and its output shaft rotates, thereby driving the spur gear 1 12 to rotate, and then driving the spur gear 2 13 to rotate, thereby driving the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 will drive the moving part to move back and forth, and the moving part drives the jet pipe 5 to move back and forth on one side of the glass 3 through the connecting frame 9, thereby fully covering the glass 3, making the cleaning more complete and improving the cleaning effect.

[0034] At the same time, the solenoid valve 18 is energized to connect the pipe 1 19, the pipe 2 20, and the bellows 4, and the compressed air inside the high-pressure tank 21 is transported to the bellows 4 through the internal pipeline of the solenoid valve 18. At this time, when the compressed air flows at a high speed, the pressure inside the pipe 19 and the dry ice storage box 15 is reduced, and the dry ice particles can be sucked out by the pressure difference, so that the dry ice particles are transported to the bellows 4 through the pipe 1 19 and the internal pipeline of the solenoid valve 18, and then the dry ice particles are mixed with the compressed air inside the bellows 4 and enter the jet pipe 5 and are discharged from the inclined jet nozzle 6;

[0035] During the cleaning process, dry ice particles use compressed air as a power source and carrier, and utilize the momentum change, sublimation, melting and other energy conversion of high-speed solid dry ice particles to quickly freeze the dirt, oil, residual impurities, etc. on the surface of the cleaned object, thereby condensing, embrittlement, and peeling off, and at the same time removing them with the airflow. First, the embrittled dirt is frozen, and the dirt breaks on the cleaned surface, changing from a viscoelastic state to a solid state, and the brittleness increases, the viscosity decreases, and the adsorption force on the surface decreases sharply. At the same time, the surface area increases, and some dirt can be automatically peeled off. Purge peeling is to generate shear force on the embrittled dirt in an environment where compressed air is used as a power source, causing mechanical fracture, and the dirt is peeled off under the action of shear force. Impact peeling is when high-speed dry ice particles collide with the enlarged dirt surface, transferring kinetic energy to the dirt, overcoming the reduced adhesion, and the shear force generated causes the dirt to be swept away with the airflow, achieving the purpose of removing the dirt.

[0036] When the compressed gas inside the high-pressure tank 21 is insufficient, the air pump 16 is started to replenish the compressed gas, which can also reduce the temperature inside the monitoring housing 1.

[0037] The device can effectively protect the glass 3 during the cleaning process to prevent it from being scratched or damaged, thereby improving the clarity of the video recorded by the monitoring device.
