The invention provides a ventilation and heat dissipation control console. The ventilation and heat dissipation control console comprises a console body provided with a hollow cavity. A rear wallboard with a hollow cavity is arranged on the console body in a communicated mode, wherein the hollow cavity of the console body is communicated with the hollow cavity of the rear wallboard. A plurality of air outlets which are communicated with the hollow cavity of the rear wallboard are formed in the rear wallboard. A plurality of air inlets which are communicated with the hollow cavity of the console body are formed in the console body. A fan is fixed inside the part, at the joint of the console body and the rear wallboard, of the hollow cavity of the console body, wherein the fan can guide air inside the hollow cavity of the console body to the hollow cavity of the rear wallboard. The ventilation and heat dissipation control console has the advantages that the control console is of a hollow cavity structure so that the air can flow freely; with the addition of the fan for reinforcement, air circulation inside the control console can be well kept, heat inside the control console is dissipated, air surrounding the control console can be driven to flow, and the air is fresher.

The invention relates to a probe comprising a spectrometer (4) capable of measuring the composition of a combustion-supporting gas after analysis of at least one portion (F13) of a light beam having interacted with the combustion-supporting gas, the spectrometer comprising: a light source (40) capable of emitting a light beam (F), an optical device comprising optical elements (50) which are configured: to guide, towards the gas (G) to be analyzed, at least one portion (F11) of the light beam, and to guide, towards a detector (41), a portion (F13) of the light beam having interacted with the gas (G), wherein: the probe (S) comprises a cage (12) suitable for being removably installed inside a channel (C) through which the gas (G) to be analyzed flows, the cage (12) being configured to permit a flow of the gas through the cage, at least one portion (F11, F12) of the light beam propagating through the cage (12) so as to be able to interact with the gas (G), the cage (12) serving as holder for an optical reflector (51) capable of reflecting, towards the detector (41), the portion (F11, F12) of the light beam that propagates through the cage and that has interacted with the gas (G), characterized in that the cage (12) is formed by an elongate tube the sidewall of which contains apertures (120) distributed over the perimeter of the wall and configured to allow the gas to pass radially through the tube, the combined area of the apertures representing more than 50% of the area of the wall of the tube, and preferably more than 80%.

The invention belongs to the fields of light rail train accessories, disaster reduction and prevention, and smart cities, and specifically relates to a light rail train sound insulation protection device, which includes a sound insulation cover part and a rainwater treatment device. The comprehensive utilization of solar energy is realized by installing solar panels on the outside of the soundproof cover, and the generated electricity can be used by the LED light board installed inside the soundproof cover, and the use of the LED light board can not only guide the vehicle, but also serve as a The use of billboards can reduce installation costs for operators. At the same time, rainwater collection and treatment devices are installed, which not only reduces the impact of rainwater on train operation, reduces the possibility of urban waterlogging during rainy seasons, but also treats rainwater at the initial stage.

The invention discloses a novel box type transformer station. The novel box type transformer station at least comprises a high-voltage switch chamber, a low-voltage switch chamber and a transformer chamber, wherein the high-voltage switch chamber, the low-voltage switch chamber and the transformer chamber are in echelonment distribution, and equipment lines in the high-voltage switch chamber, the low-voltage switch chamber and the transformer chamber are M-shaped, U-shaped or V-shaped. Different from the prior art, the novel box-type transformer station enables the volume of the box type transformer station to be reduced by 1 to 3 times compared to a conventional transformer station through innovative adoption of an upper-lower multilayer distribution structure, reduces the area of occupied land, facilitates transportation and decreases the transport cost; and a downward pedestal of the conventional box type transformer station does not have to be manufactured, such that the difficulty of a construction project is reduced, the cost is decreased, and unfavorable influences brought by moisture in the half-embedded pedestal to each device in the box type transformer station can be better avoided.

The invention discloses a hanger for chemical plating, which is characterized by comprising a clamping part, a containing part and a lifting handle part, wherein the clamping part comprises a plurality of base plates for placing plating articles, a base plate fixing device and a plating article fixing device; each base plate is provided with a lug boss which is provided with a through hole; each base plate is also provided with a hollow region; the plating article fixing device is used for fixing the plating articles on the base plate; the base plates are superposed, so that the plating articles on the base plates are mutually separated; the base plate fixing device penetrates through the through hole so as to bind the superposed base plates into an integral body, thereby forming the clamping part; the containing part comprises a basket; the clamping part is arranged in the basket; the lifting handle part comprises a lifting hook; and the lifting hook is connected to the containing part. When the hanger is applied to chemical plating, the obtained resistance coating has high uniformity, the product quality is greatly improved, and the mass production of resistance-type copper foil can be implemented. Besides, the hanger has the advantages of simple structure and low manufacturing cost.
