Description

Technical Field

[0001] The utility model relates to the technical field of earthquake monitoring stations, in particular to a monitoring station for earthquake measurement. Background Art

[0002] Earthquake monitoring has developed from a single observation to a comprehensive observation system that includes multiple disciplines and multiple measurement items, such as seismometry, electromagnetics, deformation and underground fluid. Observation technology has gradually shifted from analog observation to digital, intelligent and networked methods, and has gradually established an earthquake monitoring network that basically covers the entire country and key areas. As a result, most of the existing earthquake monitoring stations have the characteristics of miniaturization and integration.

[0003] The utility model with the existing authorization announcement number CN215005890U discloses a cabinet-type earthquake monitoring station, including a ventilation plate installed at the bottom of the cabinet body, the inner top wall of the cabinet body is threaded with a limitable and fixed screw button bolt, one end of the screw button bolt penetrates and presses against a protective cover for shielding and protection, the middle part of the protective cover is penetrated by an inclined tube body for draining liquid, and one end of the inclined tube body is drained through a drainage structure.

[0004] By adopting the above technical scheme, the cabinet body can achieve the auxiliary role of heat insulation when it is installed and used outdoors. The ventilation plate, protective cover and inclined tube body are arranged to reduce the problem of rain damage to the device caused by impact or corrosion. The ventilation plate installed at the bottom of the cabinet body eliminates the moisture problem caused by direct contact between the device and the ground, and indirectly improves the protection effect of the device when used outdoors. However, according to the above technical scheme, the seismic measurement inspection station cabinet with a high degree of integration can only play a simple protection role for the seismic detection instrument when in use, and cannot provide a suitable working temperature for the seismic detection instrument. Since the outside world has a great influence on the measurement accuracy of the seismic detection instrument, if the appropriate temperature cannot be maintained, when the outside temperature changes sharply, the internal mechanical structure of the sensor of the monitoring instrument will be affected to a certain extent, and it is easy to produce problems such as zero drift, resulting in the seismic monitoring instrument cannot work normally, causing recording interruption or abnormality, seriously affecting the stability of the seismic monitoring instrument, and also reducing the reliability of the use of the seismic measurement monitoring station.

[0005] Therefore, those skilled in the art provide a monitoring station for earthquake measurement to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a monitoring station for earthquake measurement to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] As a further solution of the utility model: the internal thread connection of the mounting bracket is provided with four mounting bolts, and the bottom end of each mounting bolt passes through the mounting bracket and extends to the bottom of the mounting bracket.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model can monitor the internal temperature of the earthquake monitor at all times by providing a temperature sensor. When the internal temperature of the earthquake monitor is too high and exceeds the internal set value of the temperature sensor, the temperature sensor can send an electrical signal to one of the fans and the compressor through a wire to start the two to work, and then use the wind force generated by the rotation of the fan to send the outside air into the rear fixed frame.

At this time, the clean air with a certain temperature enters the monitoring box to increase the temperature around the seismic monitor, further ensuring that the seismic monitor can work in a suitable temperature environment, greatly reducing the influence of the outside temperature on the monitoring accuracy of the seismic monitor, and allowing the seismic measurement monitoring station to cooperate with the temperature control mechanism to control the internal temperature of the monitoring box, ensure the working stability of the seismic monitor, and improve the reliability of the use of the seismic measurement monitoring station. The suction force provided by the suction pump can directly spray the cold air or hot air after the water is filtered and absorbed in the filter box through the air outlet nozzle to the seismic monitor, so as to ensure the cooling or heating efficiency of the seismic monitor.

Since the guide frame 9 is designed with a bottom opening, it can prevent external rainwater and impurities from entering the interior of the monitoring box 1 through the exhaust groove 8 without affecting the smooth exhaust of the exhaust groove 8.

[0027] A filter box 307 is fixedly connected to the inner wall of the monitoring box 1, and the bottom surface of each fixing frame 301 is fixedly connected to the upper surface of the filter box 307. The upper surface of the filter box 307 is fixedly connected to two connecting pipes 308. The top of each connecting pipe 308 penetrates the fixing frame 301 and extends to the interior of the fixing frame 301. A sealing door 10 is movably hinged on the left side of the monitoring box 1. A handle 11 is fixedly connected to the left side of the sealing door 10. The sealing door 10 can close the monitoring box 1 to increase the protection effect on the earthquake monitor 2. The handle 11 can facilitate the staff to open and close the sealing door 10 for maintenance.

[0028] The interior of the filter box 307 is respectively clamped with a microporous filter plate 309 and an absorbent cotton plate 310, and the bottom surface of the filter box 307 is fixedly connected to an air suction pump 311.

At this time, the temperature sensor 313 can monitor the internal temperature of the earthquake monitor 2 at all times. When the internal temperature of the earthquake monitor 2 is too high and exceeds the internal setting value of the temperature sensor 313, the temperature sensor 313 can send an electrical signal to one of the fans 302 and the compressor 304 through a wire to make the two start working, and then use the wind force generated by the rotation of the fan 302 to send the outside air into the rear fixing frame 301. After the condenser 303 cooperates with the compressor 304 and the evaporator 305 to process, the air temperature can be effectively reduced, and then enter the filter box 307 through the connecting pipe 308. After the impurities are filtered by the microporous filter plate 309 and the water is absorbed by the absorbent cotton plate 310, it enters the monitoring box 1 to reduce the ambient temperature of the earthquake monitor 2 so that it will not be higher than the normal working temperature. When the ambient temperature of the earthquake monitor 2 When the temperature is too low, the temperature sensor 313 sends an electrical signal to another fan 302 and the electric thermal resistor 306 through the same principle as above, and the fan 302 is used to suck the outside air into the front fixing frame 301, and after being heated by the electric thermal resistor 306, it enters the filter box 307 through the connecting pipe 308 to cooperate with the microporous filter plate 309 and the absorbent cotton plate 310 for filtration and dehydration. At this time, the clean air with a certain temperature enters the monitoring box 1 to increase the ambient temperature of the seismic monitor 2, further ensuring that the seismic monitor 2 can work in a suitable temperature environment, greatly reducing the influence of the outside temperature on the monitoring accuracy of the seismic monitor 2, allowing the seismic measurement monitoring station to cooperate with the temperature control mechanism 3 to control the internal temperature of the monitoring box 1, ensuring the working stability of the seismic monitor 2, and effectively improving the reliability of the seismic measurement monitoring station.
