Provided is a tank rubber cushion which has a novel structure to achieve a sufficiently high support spring rigidity in the vertical direction and a low spring property in the horizontal direction without complicating the structure or increasing parts counts. Two divided pieces of cylindrical rubber (14) are fitted over an inner axial member (12) which is inserted into an insertion hole (20) of a support portion (18). Each divided piece of cylindrical rubber (14) is provided with an axial vibration damping rubber portion (40) which is interposed between the axially opposed surfaces of a flange portion (38, 28) and the support portion (18), and a tubular axially perpendicular vibration damping rubber portion (42) which is interposed between the axially perpendicular opposed surfaces of the inner axial member (12) and the support portion (18). The axially perpendicular vibration damping rubber portion (42) of each divided piece of cylindrical rubber (14) is provided with circumferentially recessed and projected portions (48, 50) which have partially different diameters along the circumference, so that the outer circumferential surface of the inner axial member (12) and the inner circumferential surface of the support portion (18) are assembled together with gaps (52, 54) present therebetween at the recessed and projected portions (48, 50).

The invention relates to a method for starting the combustion engine in parallel hybrid vehicles, wherein the combustion engine is started via the electric engine during a load shift in the electric operation only.

The invention discloses a method for controlling a laneway floor heave through deep-hole section blasting. The method comprises the following steps of: boring a combined blast hole incline and below two edges of a laneway and a base plate under strong support, and filling explosive to blast in a special section of the deep part of the blast hole to realize that the stresses of the special sections of the laneway edges and the base plate are transmitted to the deep parts of surrounding rocks. The invention has the beneficial effects that: a rock layer of the base plate of the laneway at the position is arranged under a stress environment with a lower level and the total deformation amount of the base plate is reduced by blasting and decompressing the special sections of the deep parts of the laneway edges and the base plate; simultaneously, the special sections are arranged in the deep parts of the surrounding rocks, thus the influence of the blasting on the completeness and the bearing capability of a surrounding rock structure in a shallow part is smaller, and the surrounding rock structure in the shallow part can still effectively prevent the deformation of the surrounding rocksin the deep parts. According to the method disclosed by the invention, the surrounding rocks in the deep part of the laneway are blasted, the surrounding rocks in the shallow parts are reinforced andare protected in completeness, both of aspects are organically combined, thus the amount of the laneway floor heaves is controlled. The method of the invention is simple and convenient to construct, is easy to handle, and has better control effect on the floor heaves and wide application prospect.

The invention discloses a fan module. The fan module comprises a fan, a fan bracket and a plurality of buckles for fixing the fan on the fan bracket, wherein all the buckles are made of a damping material, are arranged between the fan and the fan bracket and are positioned below the fan. In the fan module, the fan is isolated from the fan bracket by the buckles, so that the transmission effect of vibration produced during work of the fan is greatly reduced, and noise can be effectively reduced; and the fan module also contributes to the normal work of other electronic elements in a computer case.

The invention provides a building fireproof and heat insulating hollow plate. An outer face plate and an inner face plate are parallel up and down; a cement tank is arranged on the inner face plate and connected with the inner side of the outer face plate; a heat dissipation device is connected with the cement tank and sequentially penetrates through a supporting face, a fireproof layer and the outer face plate; the heat dissipation device comprises a filling layer stacked and piled through heat dissipation mediums and further comprises a heat conducting plate connected with the cement tank and the filling layer; as for the filling layer in the direction from the cement tank to the outer face plate, the stacking density is sequentially and progressively increased, and the cross cutting area is sequentially and progressively decreased; and the progressive change range of the stacking density is 0.5-2.8 g / cm<3>, and the progressive change range of the cross cutting area is 4-50 cm <2>. According to the building fireproof and heat insulating hollow plate, heat in the hollow late can be discharged and dissipated in time when a fire occurs, the building fireproof and heat insulating hollow plate is not burned in the fire and can be recycled for many times, and the building fireproof and heat insulating hollow plate has the good fireproof, heat insulating, sound insulating functionsand is an excellent building material.

The invention discloses a preparation method of color-change-resistant wicker lampshades. The preparation method comprises the following operating steps that (1) after the surfaces of the woven and formed wicker lampshades are cleaned, the wicker lampshades are put into a drying oven to be dried; (2) modified liquid is sprayed on the surfaces of the wicker lampshades, and then the wicker lampshades are aired naturally for 3-4 days; (3) the wicker lampshades are arranged on a wooden sieve and fumigated through steam; and (4) the fumigated wicker lampshades are cooled to the room temperature, placed naturally for 3-4 days and put into the drying oven to be dried until the water content is 5% or below, and thus preparation is completed. According to the preparation method of the color-change-resistant wicker lampshades, the environmental protection effect is achieved, three-waste discharge is less in the operation process, the preparation method is suitable for large-scale industrial treatment of the wicker lampshades, the treated wicker lampshades have certain fragrance, the phenomenon that the color of the wicker lampshades is changed under lamplight can further be effectively prevented, and thus the service life of the wicker lampshades is prolonged.

The invention belongs to the technical field of fire prevention and heat insulation, and particularly relates to a fire prevention and heat insulation plate. The fire prevention and heat insulation plate includes a base and a first plate. A connecting plate is arranged in the first plate. A first groove is arranged in the right side of the first plate. A second plate is arranged in the first groove, and the upper end of the second plate is fixed to the connecting plate. The outer sides of the second plate and the first plate are evenly coated with silver paint. A rubber plate and a third plateare fixed to the base. The rubber plate is fixedly connected with the connecting plate through a box body. The rubber plate is connected in a run-through manner with the box body. The box body is provided with a snake-shaped plate. The upper end of the snake-shaped plate is connected with the second plate. The upper end of the third plate is fixedly connected with the connecting plate. The gap between the third plate and the second plate is filled with asbestos tiles. The problem of fire spread due to the fact that the fire prevention and heat insulation plate in the prior art cannot reduce the production effect of heat conduction, heat radiation and heat convection can be solved. The fire prevention and heat insulation plate of the invention can prevent fire and insulate heat, and has abroad market prospect.
