The invention discloses an electric meter box enabling more secure wiring. The electric meter box comprises a box cover and a box body; the box cover is installed at the front end of the box body; thebox cover and the box body are fixedly connected with each other through hinges; two main wire locking devices are additionally arranged inside the electric meter box; the two main wire locking devices are respectively installed on the inner walls of the left end and right end of the box body directly above two main wire holes; and therefore, after an electric meter and a total switch in the electric meter box are wired and installed, main wires passing through the main wire holes can be locked and fixed through the main wire locking devices. The wires passing through the wire holes can be prevented from loosening, and a condition that the wires are loosened and detached from the electric meter or the total switch which is caused by manual pulling of the wires can be prevented, and thus,short circuits and fires caused by the looseness and falling off of the wires can be avoided. With the main wire locking devices adopted, the use safety of the electric meter box as well as the electric meter and switch in the electric meter box can be greatly enhanced.

The invention belongs to the technical field of mechanical accessory production, and particularly relates to a clamping and fixing device for mechanical accessory production. Aiming at the problem that the existing clamping and fixing device is as only a simple hanging tool, the existing clamping and fixing device is prone to shake during spraying operation so that the production efficiency of a side cover plate is affected, the following scheme is proposed. The clamping and fixing device comprises a base plate, the top end of the base plate is fixedly provided with a plurality of partition plates, a top plate is fixedly installed between the top ends of the partition plates, both ends of the top of the top plate are both provided with strip-shaped through holes, the inner parts of the twostrip-shaped through holes are slidably connected with supporting rods, and the bottom ends of the two supporting rods are provided with driving mechanisms. In the clamping and fixing device for mechanical accessory production, effectively clamping and fixing the side cover plate is carried out by a clamping mechanism which is installed on the side face of a supporting mechanism, and in the process of paint spraying, the side cover plate can be rotated by a stepping motor, so that convenience for double-sided spraying of the side cover plate is provided, and the phenomenon of uneven paint distribution caused by shaking of the side cover plate can be avoided in the spraying process.

The invention discloses an automatic power construction robot which structurally comprises a mechanical arm, a power connection wire, a connection arm, a rotary connection seat and a fixed base; a through hole is formed in the upper side of the connection arm; the mechanical arm is connected to the interior of the through hole in an embedding manner; the connection arm is connected with the mechanical arm in an interference fitting manner; one end of the power connection wire is connected to the interior of the mechanical arm in the embedding manner and is closely connected with the interior of the mechanical arm; one end of the bottom of the connection arm is connected with the rotary connection seat through a bearing; the cross section of the rotary connection seat is of a circular structure; and the rotary connection seat is arranged on the fixed base. The automatic power construction robot provided by the invention realizes clamping operation on an object during construction and can effectively improve the clamping stability to the object, avoids the conditions of loosening, falling and the like, is beneficial to maintaining the construction order and improves the working efficiency in the construction process.

The invention discloses a generator data transmission device and method based on the Industrial Internet of Things, comprising a box body, a mounting plate, a limit block, a bottom plate, a threaded hole, a first pipe, a base, a rubber pad, a cooling fan and a data output interface , first heat sink, wireless transmitter, water pump, first spring hole, processor, leaf spring, second pipe, cavity, guide rod, coil spring, backing ring, retaining ring, guide rod hole, second spring hole and the second radiating plate, the invention forms the circulation of cooling water by transporting the cooling water through the inside of the radiating plate through the water pump, and at the same time uses the fan to blow the radiating plate to realize the joint cooling of water cooling and air cooling. The installation of the coil spring reduces the vibration of the device. The wireless transmission of data is realized through the design of the wireless transmitter and the antenna. At the same time, the wired transmission is realized through the design of the data output interface, which improves the practicability of the device.

The invention provides a receiver for a wireless communication network that is easy to maintain, including a cylindrical support frame; a cavity is provided inside the support frame for placing a cylindrical connection frame, and the connection frame extends from the top of the support frame; the support frame An adjustment mechanism is fixed on the top of the connecting frame to adjust the height of the connecting frame extending out of the supporting frame; the main body of the wireless communication network receiver is fixed on the top of the connecting frame; the front of the main body of the wireless communication network receiver is movably connected with a maintenance cover through a hinge; The interior of the main body of the communication network receiver is provided with a locking mechanism extending to the outside, which is used to control the opening or locking of the maintenance cover; the top of the main body of the wireless communication network receiver is provided with a mounting bracket; the top of the main body of the wireless communication network receiver is installed There are auxiliary support mechanisms for supporting the mounting frame. Compared with the prior art, the present invention can easily adjust the height of the receiver of the wireless communication network, which is convenient for later maintenance, and at the same time avoids the situation that the mounting frame is loosened.
