Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

As shown in Figure 1:

A heat insulation and cooling device for a tower crane machine room, including a machine room body 1 and an air conditioning device 2 installed on the machine room body 1 .

In this implementation plan: during summer construction, the temperature inside the machine room body 1 is relatively high, so the operator will be at risk of heat stroke. Currently, the air conditioning device 2 in the machine room body 1 can be installed to control the temperature in the room. The temperature is adjusted, but because the use of the air-conditioning device 2 requires the doors and windows to be closed, in a small space, due to the operation of the air-conditioning device 2, the concentration of carbon dioxide will increase, which will cause the operator to feel dizzy and fatigued.

It should be noted that the machine room body 1 is made of heat-insulating plates, so that the machine room body 1 can play a certain heat insulation role.

Further:

A ventilation component 3 is also installed on the machine room body 1.

Going further:

As shown in Figure 2-5:

Combined with the above content: the ventilation component 3 includes a fixed plate 301, an air inlet part 302, an annular filter 303, an air outlet part 304, a sliding plate 305, a wind shield 306, a magnet 307 and a fixed rod 308. The fixed plate 301 is connected to the machine The room body 1 is fixedly connected. An air inlet part 302 is fixedly connected to the upper surface of the fixed plate 301. An annular filter 303 is fixedly connected to the inner side of the air inlet part 302. An air outlet part 304 is fixedly connected to the lower surface of the fixed plate 301. The air outlet part 304 is fixedly connected to the upper surface of the fixed plate 301. A sliding plate 305 is slidably connected to the inner side of the wind element 304. A fixed rod 308 is fixedly connected to the lower surface of the sliding plate 305. A windshield 306 is fixedly connected to the upper surface of the sliding plate 305 through a connector. The windshield 306 is connected to the annular filter. The net 303 is slidingly connected, and the two magnets 307 are respectively located at the central position of the inner top of the air inlet part 302 and the central position of the upper surface of the wind shielding part 306.

In this embodiment: during use, when ventilation is required, the fixed rod 308 can be moved upward, so that the fixed rod 308 drives the sliding plate 305 to move. In this way, driven by the sliding plate 305, the stopper can be driven through the connecting piece. The wind piece 306 moves. At this time, the wind shield 306 moves upward and gradually loses contact with the fixed plate 301. When the wind shield 306 moves to the maximum limit position, the magnet 307 located on the wind shield 306 will contact with the fixed plate 301. The magnets 307 on the air inlet part 302 are attracted to each other. When the fixing rod 308 is released, the wind shield 306 will not slide down. At this time, the wind can enter through the air inlet hole on the air inlet part 302 and then pass through the wind shield. The gap between the component 306 and the fixing plate 301 can finally enter the machine room body 1 through the air outlet component 304, thereby realizing air circulation. When ventilation is not needed, you only need to pull the fixing rod 308 downwards. When the force exerted by the hand is greater than the adsorption force between the two magnets 307, the two magnets 307 will be out of contact. At this time, the fixed rod 308 will be moved downward, gradually driving the windshield 306 to move downward, and causing the windshield to move downward. 306 re-block the ventilation between the fixed plate 301 and the air inlet 302, so that the need for non-ventilation can be achieved.

It should be noted that a ventilation hole is provided at the center of the fixed plate 301, and the ventilation hole can be blocked or opened through the windshield 306, thereby achieving the need for ventilation.

It should be noted that the ventilation holes of the air inlet 302 are opened on all sides, and the outward side is larger and the inward side is smaller, so as to avoid the entry of rainwater in rainy and snowy weather.

To take it a step further;

In an optional embodiment, the ventilation assembly 3 also includes a first electric telescopic rod 309, a digit-shaped fixing member 310, a controller 311 and a carbon dioxide concentration detection sensor 312. The housings of the two first electric telescopic rods 309 are in contact with each other. The fixed plate 301 is fixedly connected, the extending end of the first electric telescopic rod 309 is fixedly connected to a digit-shaped fixing piece 310, the digit-shaped fixing piece 310 is fixedly connected to the fixed rod 308, the controller 311 is fixedly connected to the fixed plate 301, and the control A carbon dioxide concentration detection sensor 312 is fixedly connected to the lower surface of the container 311.

In this embodiment, the carbon dioxide concentration can be detected by the carbon dioxide concentration detection sensor 312. When the concentration reaches the limit value, the controller 311 can control the first electric telescopic rod 309 to move, thus driving the several-shaped fixing member. 310 moves, so that the several-shaped fixing member 310 drives the fixing rod 308 to move, thereby realizing automatic control of the position of the wind shield 306, thereby realizing automatic control of ventilation.
