The invention discloses a multi-ball point pre-buried pile for geological disaster early warning, which belongs to the field of geological disaster early warning. It is a multi-ball point pre-buried pile for geological disaster early warning. Through the setting of the pre-buried pile, when the geological subsidence occurs, The pre-breaking sinking rod is subjected to downward pressure, and acts on the lower outer marking end, so that the surface of the marking ball is notched, and the colored sand inside overflows. When the pre-breaking sinking rod breaks, the outer marking end recovers after losing the pressing force. , the gap disappears, and the sand mining stops overflowing. When the pre-embedded pile detects that there is subsidence, the soil near the pre-embedded pile can be excavated, and the specific subsidence situation can be judged according to the amount of colored sand. , the sharp thorns gradually approach the inner photosphere until it will pierce, causing the fluorescent liquid inside to overflow, which can be used for auxiliary marking of geological subsidence, which will help the staff to intuitively judge the situation of geological subsidence, and facilitate corresponding Countermeasures to reduce potential safety hazards.

The invention discloses a heat-induced self-lubricating bearing wear-resistant shaft sleeve, which belongs to the technical field of wear-resistant shaft sleeves. Set the sleeve, the embedded sleeve and the shaft sleeve hole are embedded and matched with each other, which is easy to install the sleeve body stably. There is an oil storage bag filled with lubricating oil inside the heat transfer sleeve, and the upper and lower sides of the heat transfer sleeve are equipped with oil storage bags. The closely attached thermal expansion packing layer, after the bearing and the shaft sleeve rub against each other to generate heat, the heat is transferred to the heat conduction sleeve through the heat conductor connected between the sleeve body and the embedded sleeve, as the thermal expansion condition of the thermal expansion packing layer, a After the heat-expandable packing layer is thermally expanded, the oil storage bag can be squeezed in two directions, so that the lubricating oil inside the oil storage bag can overflow to the oil outlet groove through the oil outlet pipe, and oil can be supplied to the bearing in the casing, which is targeted and flexible Oil supply operation without manual operation.

The invention discloses a method for treating sediment deposition in a river channel. A sand extractor includes blades which are placed in a riverbed through a pile foundation and driven by an electric motor to rotate; the sand extractor stirs water in the riverbed to form a vortex and stirs sediment at the bottom of the riverbed, the sediment enters a sand storage tank with the vortex, and treatment of sediment deposition is realized; the lower blade bends downward to disturb the sediment on the riverbed surface, so that the sediment at the bottom suspends in water; the upper blade bends upward, the suspended sediment in the water are lifted to the surface; through slope-shaped burrock, inflow of water flow containing the sediment and precipitation of the sediment are convenient; cables are laid out in the riverbed and the pile foundation, and the motion trail of the water flow containing the sediment is avoided from disturbing; and through an automatic opening and closing sensor and timer, monitoring of the deposited sediment amount in the riverbed and automatic controlling of electric motor opening and closing are realized. According to the method, the structure is simple, operation is convenient, the maintenance cost is low, implementation is safe and reliable, the method is especially suitable for the front of a sluice gate on a river reservoir with a lot of sediment, and the method has high practicability and wide applicability.

The invention discloses a semi-dry airflow forming preparation process of fiberboard, which belongs to the field of fiberboard preparation technology. A plurality of guide rods are set up on the mold, and the guide rods are movably sleeved with air-guiding overflow rubber balls, which are interrupted to both ends of the mold. On the one hand, the introduced air flow is conducive to the preliminary dispersal of the agglomerated fibers; The agglomeration member breaks up the agglomerated fibers mechanically during the movement, further improving the fiber carding effect, and intermittently applies a magnetic field under the mold to make the magnetic deagglomeration member reciprocate up and down, which not only effectively adjusts the breaking depth, but also realizes Under pressure, with the overflow of the rubber material and airflow, the rubber material is evenly attached to the fiber filaments, which improves the adhesive molding effect, and the air bubbles formed at the air guide overflow rubber ball are easy to blow away the small agglomerates.

The invention provides a protective device and a method of an electric main shaft and a thinning machine. The protective device of the electric main shaft comprises a receiving module for receiving cooling liquid overflowing from a grinding cooling liquid inlet center hole of the electric main shaft, a sensing module for connecting with the receiving module and detecting voltage between two reserved detecting points of the receiving module and outputting voltage signals, a filter circuit module for conducting filtering on output voltage signals of the sensing module and outputting filtered voltage signals, an amplifying circuit for amplifying the filtered voltage signals and outputting amplified voltage signals, a comparing circuit module for outputting a first comparing result signal when the amplified voltage signals are smaller than a predetermined threshold value and a control module for controlling the electric main shaft to stop operating or to operate in a predetermined mode according to the first comparing result signal. The protective device of the electric main shaft has the advantages of preventing the grinding cooling liquid of the electric main shaft from entering an air bearing after overflowing, and protecting the electric main shaft against / from damage.

The invention provides a solid wheel vulcanization mold, comprising: an upper mold: including an upper mold cavity, having a mating surface matched with a lower mold; a lower mold: including a lower mold cavity, having a mating surface matched with an upper mold; an upper mold mating surface A mold clamping surface is formed at the mating surface of the lower mold, and a first rubber running structure is provided at the clamping surface, and the first rubber running structure includes a glue overflow groove and a first rubber running channel, and the rubber running channel is connected to the first rubber running channel. The overflow groove is connected and extends to the outside of the clamping surface. The rubber running structure is set on the clamping surface of the mold, that is, the upper mold and the lower mold parting surface are provided with a glue overflow groove and a glue running groove, which can realize the overflow of excess rubber in the mold cavity, which is beneficial to control the intermediate parting of the product There is no thickness of flash on the surface, which solves the problem of air bubbles on the appearance of vulcanized products, and at the same time facilitates the control of product size.
