The invention discloses a cross-shaped quakeproof platform. The cross-shaped quakeproof platform comprises a slide seat body, two guide rails, more than one keeper and a plurality of rollers, wherein the two guide rails are slidably arranged on the upper end surface and the lower end surface of the slide seat body, the more than one keepers are arranged between the slide seat body and the guide rails correspondingly, and the rollers are mounted on the keeper; two rail grooves are formed in the upper end surface and the lower surface of the slide seat body in a concave mode correspondingly, moreover, the rail grooves of the upper end surface and the rail grooves of the lower end surface are mutually arranged in a crosswise interlaced shape, more than one first roller guide channels parallel to the corresponding rail groove are formed in the groove bottom surface of each rail groove, and second roller guide channels parallel to the corresponding rail groove are formed in the vertical wall surfaces of the two sides of each rail groove correspondingly; the guide rails are slidably connected in the rail grooves in a sleeved mode, each guide rail is provided with more than one third roller guide channels corresponding to the corresponding first roller guide grooves, and fourth roller guide channels corresponding to the corresponding second roller guide channels are formed in the two sides of each guide rail correspondingly; and a plurality of rollers are rotatably arranged in the keeper in an embedded mode correspondingly. According to the cross-shaped quakeproof platform, the quake insulation equipment can reduce earthquake force transmitted to an upper structure.

The invention relates to a working protection device for a blast vibration sensor, and belongs to the field of safety protection of sensors. The device comprises an outer protective layer, an outer protective cover, a side energy consumption ring, a top energy consumption ring, an inner protective cover, filling particles, a shock-insulation supporting seat and a sensor connection hole. When blasting occurs, blasting gravels and dust generated by the blasting are directly obstructed by an outer rubber protective layer, generated larger blasting flying stones and blasting shock wave are blockedby the outer protective layer, the outer protective cover, the side energy consumption ring, the top energy consumption ring, the inner protective cover and the filling particles together, vibrationtransmitted into the ground is reduced through the shock-insulation supporting seat, and the device is prevented from absorbing the vibration of the ground to affect the monitoring. The working protection device for the blast vibration sensor can resist the pressure waves and vibration waves in the blasting shock waves and the impact of the blasting flying stones, can protect the sensor and ensurethe smooth progress of the blasting monitoring.

The invention discloses a high-precision resonant mode quartz temperature sensor with a plurality of arrow-shaped vibrating arms. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms aims to solve the problems of large volume, fixed thermosensitive quartz resonator, complex mounting structure, slow response speed and the like of an existing temperature sensor. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms comprises an integrated packaging part and a thermosensitive quartz resonator, wherein the integrated packaging part is filled with helium gas; the integrated packaging part comprises a pipe cap and a pipe seat; the pipe seat comprises an insulator, a first pin and a second pin; the thermosensitive quartz resonator comprises a base region and n vibrating arms, and n is an even number not less than four. According to the high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms, the mechanical strength of the thermosensitive quartz resonator is improved, a parasitic vibration mode in a conventional structure is reduced, structures are simple to support, fixand mount, high cost rate is achieved, and more importantly the precision, response speed, repeatability and long-term stability of the sensor are improved. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms has low working frequency, low power consumption, high precision, high response speed, clean frequency spectrum and high anti-interference capability.
