The invention relates to a device for fixing a wind tunnel wedge, which belongs to a wind tunnel simulation device and method. The device includes a detachable base, a metal cap, a screw, a nut, a rubber pad and a wedge vertical shaft; the detachable base is a metal plate with a T-shaped groove, which is set at the bottom of the wedge vertical shaft, and the T-shaped groove A layer of rubber cushion is adhered to the bottom of the inner and metal plate; a layer of rubber cushion is adhered to the top of the metal cap; one end of the vertical shaft of the wedge is fixed in the T-shaped groove, and the other end is connected to a screw rod, which is covered by the metal cap Inside; by rotating the nut on the screw rod, the metal cap fastened on the upper part of the screw rod is pushed to move upward, so that it is pressed against the top of the wind tunnel to fix the wedge. The groove of the base of the invention constrains the local deformation and instability of the wedge, the base increases the contact area between the bottom of the wedge and the bottom surface of the wind tunnel, and increases the stability of the wedge; the multi-layer rubber cushion makes the wedge and the top and bottom plates of the wind tunnel The contact is more uniform, which increases the anti-skid ability between the two, and makes the fixing of the wedge more reliable.

The invention relates to a linkage compression type pump body gas tightness detecting clamp. The linkage compression type pump body gas tightness detecting clamp comprises a baseplate, wherein a detecting air cylinder is fixed on the rear side of the baseplate; a horizontal baffle is arranged at the middle part of the baseplate; a longitudinal round hole is formed in the middle of the baffle; a pump body is communicated in the round hole; a compressing air cylinder is fixed on the front side of the baseplate; a left linkage compressing device and a right linkage compressing device are arranged in the middle of the baseplate and are symmetrically arranged on the left side and the right side of the axis of the compressing air cylinder. According to the invention, the linkage compression type is adopted, so that the number of the air cylinder is reduced, the production cost is reduced, and the convenience for detection is increased; the synchronism of devices on the compression of the pump body is improved, the pump body offset phenomenon caused due to the pump body compressed by a plurality of independent air cylinders respectively can be avoided, the pump body don't need to be adjusted and calibrated by the detecting air cylinder, and the detection efficiency and the production efficiency can be improved.

The invention discloses a vertical compression type rubbish transfer station. The vertical compression type rubbish transfer station comprises a pressing head, a rubbish compression tank and an oil cylinder mechanism. Stand columns are symmetrically disposed on the two sides of the rubbish compression tank; the upper end of the oil cylinder mechanism is connected to cross beams at the tops of the stand columns; the lower end of the oil cylinder mechanism is connected with the pressing head; pressing head positioning and guiding blocks are disposed on the pressing head; tank guiding blocks are disposed on the rubbish compression tank; the pressing head positioning and guiding blocks and the tank guiding blocks are attached to the stand columns and vertically slide and guide with the stand columns as guide ways; tank lifting rings are disposed at the top of the rubbish compression tank; a retractable bolt mechanism is disposed on the pressing head, and bolts extend out of the retractable bolt mechanism to be inserted into the tank lifting rings so as to connect the pressing head with the rubbish compression tank. Lifting and compression are achieved respectively through different oil cylinders; the traveling distance of the oil cylinders is short, the acting force is stable, guiding is smooth, and it is guaranteed that the acting force of the pressing head is stably exerted on rubbish lumps; the compression stability is improved; the compression density of the rubbish lumps is increased; the rubbish transportation cost is reduced.
