In order to research and monitor information of a side slope soil layer and prevent a possible landslide phenomenon of a side slope, a sensor is usually embedded into the side slope soil layer to record information such as temperature and humidity in the side slope soil layer, and the stability of the side slope is reflected according to the information such as the temperature and the humidity, so that an early warning effect is achieved. When burying the sensor in the soil layer of side slope, in order to improve the efficiency of burying, reduce the damage that causes the sensor when burying, the one side of this application embodiment provides a calamity monitoring devices, it can improve the efficiency that the sensor buried the side slope soil layer through the drilling rod, simultaneously, bury the in-process of side slope soil layer at the sensor, can enough break open the side slope soil layer through the casing that is in the state of enclosing and protect the sensor, again can be after burying the side slope soil layer, make the casing be in open state, make the sensor can accurate monitoring side slope soil layer various information.

As shown in fig. 1, the disaster monitoring apparatus includes: the protection tube comprises at least two flaps 310 (fig. 1 shows that the protection tube comprises two flaps 310 which are arranged in a mutually-folded manner), the at least two flaps 310 can be mutually enclosed, so that the protection tube has a hollow inner cavity, namely, in an enclosed state, the at least two flaps 310 are mutually close and enclosed, as shown in fig. 1, when the flaps 310 far away from one end of the drill rod 100 are in the enclosed state, not only the side wall is enclosed, but also the end far away from the drill rod 100 (namely, one end of the protection tube used for breaking the side slope soil layer, as shown in fig. 1 and fig. 3, the lower end of the protection tube) is closed, so that the sensor 500 is arranged in the inner cavity, and the sensor 500 inside can be protected by the protection tube (at least two flaps 310) in the enclosed state. At least two petals 310 are hinged to the drill rod 100 respectively, and the action mechanism is in transmission connection with the at least two petals 310, so that the pile casing can be controlled to be in an open state or a closed state, the sensor 500 is inserted into a side slope soil layer under the protection of the pile casing, and the sensor 500 is opened after the side slope soil layer is inserted, so that the acquisition of the side slope soil layer information can be conveniently carried out by the sensor 500.

As shown in fig. 1, when the sensor 500 needs to be inserted into a side slope soil layer, an external force can be applied to the action mechanism, so that after the action mechanism is driven, the action mechanism drives at least two flaps 310 to approach each other and be in an enclosing state, so that the sensor 500 in the inner cavity of the casing is enclosed and protected, and in the process of being inserted into the side slope soil layer, the flaps 310 directly contact with the side slope soil layer, so that the sensor 500 is prevented from being damaged due to direct contact with the side slope soil layer in an exposed state, and the sensor 500 is particularly suitable for some side slope soil layers with hard soil; as shown in fig. 2, after the drill rod 100 drives the casing to extend into the side slope soil layer in place, external force can be applied to the action mechanism, so that the action mechanism is driven, at least two petals 310 are driven to be away from each other and to be in an open state, at the moment, the sensor 500 in the casing is exposed, so that information in the side slope soil layer can be collected by the sensor 500, and thus, in the process of burying the sensor 500 into the side slope soil layer, the sensor 500 can be protected by the casing in an enclosing state, and the casing can be in the open state after being buried into the side slope soil layer, so that the sensor 500 can accurately monitor various information of the side slope soil layer.

Referring to fig. 2, after the soil layer of the slope is stretched in place, the two flaps 310 are driven by the action mechanism to move away from each other, so as to expose the sensor 500 in the casing. Of course, in other embodiments, the casing may also include three flaps 310, four flaps 310, five flaps 310, and the like, and no matter the casing includes several flaps 310, the casing should have two states of enclosure or opening when the actuating mechanism is driven, and should form a structure in which the side wall encloses and breaks the end enclosure of the soil layer in the enclosure state.
