The invention discloses a wireless anti-theft alarm terminal for a well lid. The wireless anti-theft alarm terminal comprises an outer box, wherein the outer box is composed of an upper lid and a lower lid, the upper lid is helically connected with the lower lid so as to well play a water proof and moisture proof function, a fixed connecting structure is arranged in the upper lid of the outer box, the fixed connecting structure is respectively connected and fixed with a power supply switch and a circuit board through screws, a power supply groove is formed in the upper lid of the outer box, a power supply is installed in the power supply groove, the power supply is connected with the power supply switch through an electric wire, the power supply switch is connected with the circuit board through the electric wire, the power supply switch is a gravity conductive ball sliding rail switch, and a wireless anti-theft alarm terminal (which is arranged adjacent to the circuit board) of the well lid can automatically organize a network, the circuit board is connected with an antenna through the electric wire, a connecting device of an external power supply is arranged in the upper lid, and a metal device connected with the antenna is arranged in the upper lid, so that the power consumption of the gravity conductive ball sliding rail switch is low, the use is safe, the open state of the well lid can be automatically monitored, and the position of the antenna can be automatically selected according to external environments, so that a signal is good and the antenna can be normally used under severe natural environments.

The invention provides a dampproof packaging box for plastic materials, and belongs to the field of packaging boxes. The dampproof packaging box comprises a box body, a partition plate is fixedly installed inside the box body, a plurality of through holes are formed inside the partition plate, a dampproof agent layer is arranged at the bottom of the partition plate, a baffle is fixedly installed inside the box body, the bottom of the baffle and the top of the partition plate are fixedly installed, and a plurality of air holes are formed in the baffle. According to the dampproof packaging box for plastic materials, since a drying device is arranged, the ground is affected by damp, the interior of the box body is damped, a heater can remove internal residual dampness, products in the box body are prevented from being affected with damp and producing unpleasant odor, the box body achieves the good waterproof function, the products placed in the box body can be protected, the service lifeof the box body is prolonged, additional economic losses are reduced, applicability is high, the waterproof and dampproof effects can be achieved through a bottom plate, the packaging box is kept a certain distance away from the ground, and rainwater is prevented from entering the packaging box to affect the product quality.

The invention discloses a solar cell module having good heat dissipation function. The solar cell module comprises a solar cell panel, a protection substrate, a buffer part and a frame; the buffer part comprises an upper buffer part and a lower buffer part; the buffer part is divided into a solid buffer layer and a gas buffer layer; the buffer part near one side of the solar cell panel is the solid buffer layer; the gas buffer layer of the lower buffer layer forms a closed cooling gas buffer chamber; a part at four sides of the substrate and having a solar cell passes through the substrate and the solid buffer layer of the lower buffer layer, so that holes are formed; a heat conduction material is filled in the holes; and the gas buffer layer of the lower buffer layer is provided with a heat conduction plate corresponding to the holes. The solar cell module disclosed by the invention has good heat dissipation function.

The invention discloses a combined electric control equipment room with a moisture-proof function, and the room comprises a box body formed by an electric control bin, a first bin chamber and a second bin chamber; a ventilation sleeve is arranged in the electric control bin, and an annular control is arranged on the inner ring surface of the ventilation sleeve; and a plurality of groups of first ventilation openings and second ventilation openings are correspondingly formed in the circumferential direction of the annular control and the ventilation sleeve; a group of supporting net plates and ventilation switching boxes are arranged on the inner bottom surface of each of the first chamber and the second chamber; the rear end face of the annular control piece is connected with a first transmission belt wheel through a rotating shaft, the rear ends of all rotating rods of the ventilation switching box are connected with branch belt wheels, a main belt wheel is arranged in the middle of the rear side face of the ventilation switching box and is in belt transmission with all the branch belt wheels through a transmission belt, and the rear end of the main belt wheel is connected with a second transmission belt wheel through a rod piece; the first transmission belt wheel and the second transmission belt wheel are driven through a transmission assembly. According to the device, ventilation and sealing in the box can be freely switched, accumulated water is prevented from flowing backwards, and the waterproof and moisture-proof effects are achieved.
