The invention discloses a wall switch socket front side wiring system. A wiring seat of a switch socket is arranged on a front surface of a panel. A wire arranging frame is additionally arranged between the panel and a bottom box so that an electric wire is easily positioned to a preset wiring area. A force application portion of the wiring seat is operated on the front surface of the panel, and an internal mechanism of the wiring seat acts to clamp an electric wire inserted into the wiring seat. The electric wire is reliably connected and conducted with a switch function component and a jackfunction component on the panel. And after the electric wire is connected, subsequent operation does not disturb the electric wire so that connection between the electric wire and the wiring seat is more stable and reliable, and the wiring is more convenient. The invention belongs to the electric appliance technology field.

A refrigeration appliance, comprising a box body (1), a door (2) and a hinge assembly (3) connecting the box body (1) and the door (2), the hinge assembly (3) comprising: The mounting part (31) of the box body (1); the hinge part (32), which is connected to the mounting part (31) and has a hinge shaft (320) connected to the door (2); and the adjustment unit, comprising An adjustment piece (30) connected to the hinge piece (32), the adjustment piece (30) is used to adjust the position of the hinge piece (32) relative to the installation piece (31) along the adjustment direction, and the adjustment direction It is the width direction of the door (2) or the front-rear direction of the box body (1). The technical solution can solve the appearance / sealing problem caused by the uneven distance between two doors (2) or between the door (2) and the box body (1).

The invention discloses a mining optical fiber temperature sensor probe which comprises a temperature sensing area shell, an optical fiber and an anchor head, wherein one end of the temperature sensing area shell is provided with an opening; a fiber bragg grating (FBG) is arranged in the temperature sensing area shell; the optical fiber is connected with the FBG; the anchor head is sleeved outside the optical fiber and is fixedly connected with the temperature sensing area shell; the other end of the anchor head is fixedly connected with the head of a coil pipe; and the coil pipe can be freely bent and cannot be twisted. The mining optical fiber temperature sensor probe can be applied to measuring the temperature of the inner part of a coal mine, particularly deep rock. According to the probe, the FBG is adopted as a temperature sensing element, the coil pipe is adopted as a protecting pipe, and the anchor head which is provided with bulging thorns and is used for fixing the tail end of a temperature sensing area, and an expansion device used for fixing the tail part of a sensor and a coal seam are designed. The mining optical fiber temperature sensor probe has a simple and reliable structure, is convenient to carry and mount under a mine, and is convenient to use.

A main pulling device of a bag making machine comprises a pull roll, a driving mechanism for driving the pull roll, and a coaxial multi-dandy roll swinging arm mechanism which is positioned above the pull roll, wherein the pull roll is a steel roll of which the surface is provided with a ceramic layer; the coaxial multi-dandy roll swinging arm mechanism comprises an upper slide rod, a lower slide rod, and a plurality of swinging pressing roll assemblies which are mounted on the upper slide rod and the lower slide rod; each swinging pressing roll assembly comprises a bracket, a swinging arm which is hinged with each bracket, a dandy roll which is pivoted to each swinging arm, and a cylinder for driving each swinging arm to swing; a first through hole through which the upper slide rod passes is formed in each bracket; a locking seat is arranged at the first through hole in one side of each bracket; a second through hole through which the lower slide rod passes is formed in each bracket. According to the device, the brackets are strictly processed according to a drawing by a processing center based on the mounting standard of the swinging arms, the cylinder and a slide sleeve, and each bracket is provided with the same hole size. Therefore, the difficulty in mounting operation is reduced, and the mounting accuracy is ensured.

The invention discloses a method for simultaneous desulfurization, denitrification and particle removal of hypochlorite based on ultraviolet radiation enhancement, which has the following steps: the atomized aerosol formed by the hypochlorite aqueous solution is irradiated with ultraviolet light, and the atomized aerosol The photolysis reaction of hypochlorite generates strong oxidizing ROS free radicals, and the atomized aerosol containing strong oxidizing ROS free radicals is fully mixed with the flue gas. The treated flue gas and the reacted atomized aerosol are wetted Washing treatment, the treated flue gas is discharged into the atmosphere after removing water mist by a demister. The invention also discloses a hypochlorite simultaneous desulfurization, denitrification and particle removal device based on ultraviolet radiation strengthening. The invention adopts the ultraviolet light irradiation method to significantly strengthen the desulfurization and denitrification effect of hypochlorite, and the mixed reaction between the atomized aerosol and the harmful gas in the flue gas greatly enhances the gas-liquid contact area, improves the gas-liquid mass transfer efficiency, and the ultraviolet light reaction The device reduces the system complexity and the difficulty of installation and operation, and reduces the initial investment cost of the system.

The invention provides an extensometer auxiliary assembly, which is used to cooperate with a contact type high-temperature extensometer to perform a high-temperature mechanical test, and includes a buckle assembly, which includes a U-shaped sleeve and a rotating block; The bottom and two sides of the shape, the bottom has an inner knife edge; the rotating block has a rotating part, a crimping part, a counterweight part and a connecting part, and the rotating block and the U-shaped sleeve define the channel of the test piece for the test section of the test piece Pass through, the inner knife edge and the end side knife edge are located on the opposite sides of the test piece passage, and the counterweight keeps the end side knife edge to rotate to narrow the test piece passage, so that the inner knife edge and the end side knife edge are respectively pressed from both sides of the test piece. Tighten the two opposing surfaces of its test section. The present invention also provides a high-temperature mechanical test device comprising the above-mentioned extensometer auxiliary assembly. The aforementioned extensometer auxiliary components can reduce the risk of extensometer slipping, improve the success rate of the test, and can also reduce the difficulty of installation and operation of the contact high-temperature extensometer.
