Abstract: A mounting bracket is disposed on at least one of a window sill and a window frame, and the mounting bracket is configured to support the window air conditioner. The mounting bracket includes a support member, a base and an adjustment member. The support member is connected to the window air conditioner. The base is disposed on the window sill. A lower end of the adjustment member is connected to the base. The adjustment member is provided with a first adjustment portion, and the support member is provided with a second adjustment portion, the first adjustment portion and the second adjustment portion mate with each other and are configured to adjust the distance between the support member and the surface of the window sill.

Abstract: A window air conditioner includes a housing, an indoor heat exchanger, an indoor fan assembly, an outdoor heat exchanger, an outdoor fan assembly, an indoor air duct casing body, and a sound insulation board. The sound insulation board is provided on on a side of the indoor air duct casing body toward the outdoor fan assembly, separates the outdoor heat exchanger and the outdoor fan assembly from the indoor fan assembly and the indoor heat exchange, and extends from a bottom to a top of the indoor air duct casing body.

Abstract: A switch sliding sleeve device for oil-gas exploitation and switching method thereof, an oil-gas exploitation tool and a switching method of a wall through hole thereof are disclosed. The disclosure relates to the technical field of oil-gas exploitation, and solves the technical problems in the prior art that the switching operation steps of a wall through hole of an outer cylinder are tedious and complex, and a large amount of manpower and material resources are consumed. The switch sliding sleeve device for oil-gas exploitation and the oil-gas exploitation tool include an outer cylinder, a switch sliding sleeve mechanism and a trigger. When the trigger is put into the outer cylinder and punching triggers the switch sliding sleeve mechanism, the switch sliding sleeve mechanism is capable of being switched from a state of opening the wall through hole to a state of closing the wall through hole until is triggered by the trigger or another trigger again.

Abstract: The present disclosure provides a data transceiving method, a data transceiving device, a wavelength configuration method and a wavelength configuration device. The data transceiving method includes that a first optical module receives control information sent by a second optical module; the first optical module adjusts transmission and receiving wavelengths according to the control information; and the first optical module executes transmission and receiving of data with the second optical module according to the adjusted transmission and receiving wavelengths.

Abstract: A sealing assembly for a dissolvable bridge plug, a dissolvable bridge plug and a sealing method for a gap are disclosed. The sealing assembly for dissolvable bridge plug includes a seal ring and a support ring. The support ring includes at least two supporting parts capable of sliding in the radial direction relative to each other. An axial end face of the support ring is butted with an axial end face of the seal ring. Respective central holes of the support ring and the seal ring are capable of being sleeved outside a component of dissolvable bridge plug. The supporting parts of the support ring in an expansion state are capable of exerting an axial thrust on the seal ring to prevent the seal ring from deforming in the axial direction.

Abstract: A reducing support ring for a bridge plug and a bridge plug for sealing or packing boreholes or wells. The reducing support ring for the bridge plug includes a ring-shaped body with a setting surface provided on a circumferential outer wall or end face of the ring-shaped body. Deformation of the ring-shaped body under an axial compression force allows the setting surface of the ring-shaped body to be abutted against and positioned on an inner wall of a sleeve where a bridge plug is located and to form a surface contact-type sealed connection with the inner wall of the sleeve. The bridge plug includes the reducing support ring. The reducing support ring and the bridge plug improve the plugging effect and anchoring performance of the bridge plug and the convenience of construction.
