[0002] The heat exchange station is an important component of a central heating system and is mainly used for heat exchange in the heat supply process. The heat exchange station functions to transfer hot water or steam from a heat source (such as a heat plant or a boiler room) to a user's heating system or to recover heat in the user's return water, thereby ensuring efficient operation of the entire heating system.
[0003] The heat exchange station is generally composed of some equipment combinations, such as a shell-and-tube heat exchanger, a shell-and-tube heat exchanger and a plate heat exchanger. These devices will generate a certain high temperature after long-term use, and the high temperature will generate water vapor. The water vapor will condense into water droplets when it floats to the wall. These water droplets will fall into the cooling pool. With long-term falling, the water level in the cooling pool will increase, which will threaten the subsequent normal use of the equipment. The current unattended alarm device still has some defects when detecting the heat exchange station. There are three situations of alarm in the heat exchange station, 1: water level is too high, 2: smoke affects the normal use of the device, and 3: humidity is too high. However, the existing unattended alarm device cannot clearly alarm and remind according to the above three situations, so that the staff needs to carry three items for prevention when handling, which not only increases the weight of the staff, but also delays the best rescue opportunity.

[0026] The upper surface of the bottom plate 1 is provided with a patrol alarm device 3, the patrol alarm device 3 comprises a sliding groove 301, the sliding groove 301 is arranged on the upper surface of the bottom plate 1, and the inner wall of the sliding groove 301 is slidably connected with a moving block 302; through the sliding connection between the sliding groove 301 and the moving block 302, the moving direction of the moving block 302 can be guided, thereby facilitating subsequent patrol work; the outer surface of the moving block 302 is fixedly connected with a square plate 303, the upper surface of the square plate 303 is provided with a double-head motor 304, the output end of the double-head motor 304 is fixedly connected with a moving wheel 305, the outer surface of the moving wheel 305 is in contact with the inner bottom wall of the sliding groove 301, through the work of the double-head motor 304, the moving wheel 305 can be driven to rotate, thereby realizing the displacement of the moving block 302 and the guarding work of the heat exchanger body 2, ensuring the normal use of the heat exchanger body 2, and the material of the moving wheel 305 is rubber, the material of rubber can increase the contact between the moving wheel 305 and the sliding groove 301, ensuring the stability when the moving block 302 is moved, thereby ensuring the subsequent guarding effect of the heat exchanger body 2.
[0027] As shown in Figure 3 and Figure 4 :
[0028] A column 306 is fixedly connected to the upper surface of the movable block 302. The column 306 facilitates the subsequent installation of other devices. A control panel 307 is installed on the outer surface of the column 306, which controls the switching on and off of the entire device, ensuring its normal operation. The patrol alarm device 3 also includes a water collection tank 308, which is located on the upper surface of the base plate 1. A guide rod 309 is slidably connected to the inner wall of the water collection tank 308. The other end of the guide rod 309 is fixedly connected to the outer surface of the column 306. The sliding connection between the water collection tanks 308 can guide and limit the movement of the column 306, thereby ensuring the subsequent movement effect of the column 306. A fixing rod 310 is fixedly connected to the outer surface of the column 306, and a water level detector 311 is fixedly connected to the other end of the fixing rod 310. The water level detector 311 can detect the water level, ensuring the normal use of the heat exchanger body 2. The water level detector 311 is located on one side of the heat exchanger body 2, close to the heat exchanger body 2, and can accurately detect the water level position to avoid accidents.
[0029] like Figure 2 As shown:
[0030] A microcontroller 312 is fixedly connected to the outer surface of the column 306. The microcontroller 312 is connected to the water level detector 311 via digital signal to ensure the stability of subsequent signal transmission. Two flashing lights 313 are fixedly connected to the outer surface of the column 306. The two flashing lights 313 will flash to achieve the warning effect and ensure that the staff can deal with it quickly. The outer surface of the two flashing lights 313 is covered with a lampshade 314, and the lampshade 314 is connected to the outer surface of the column 306. The lampshade 314 has two colors, so the flashing lights 313 will show different colors when flashing, so that the staff can quickly know the alarm information and deal with it quickly without affecting the normal use of the heat exchanger body 2. A humidity sensor 315 is fixedly connected to the outer surface of the column 306. The humidity sensor 315 is a DHT11 model.

The outer surface of the stand 306 is fixedly connected with a battery 318. The battery 318 is electrically connected with the smoke alarm 316, the water level detector 311, the double-head motor 304 and the humidity sensor 315 through wires, so that the normal use of the equipment can be ensured.
[0033] The implementation principle of the heat exchange station unattended alarm device is as follows: when the heat exchanger body 2 is guarded and inspected, first, the double-head motor 304 is started, the double-head motor 304 drives the moving wheel 305 to rotate in the inside of the chute 301, and then the displacement of the stand 306 is realized, and the inspection of the heat exchanger body 2 is started. When the water level detector 311, the smoke alarm 316 or the humidity sensor 315 detects that the value exceeds the predetermined threshold, first, the single-chip microcomputer 312 receives the signal that the value exceeds the predetermined threshold, then the single-chip microcomputer 312 starts to transmit the signal to the flashing lamp 313, at this time, the battery 318 starts to supply power to the flashing lamp 313, and the flashing lamp 313 starts to flash. By using the color of the lampshade 314 itself, the single-chip microcomputer 312 receives the signal sent by the smoke alarm 316, and the single-chip microcomputer 312 immediately sends a working signal to the loudspeaker 317, and the loudspeaker 317 makes a sound. The workers can quickly select appropriate items to eliminate hidden dangers according to the color and sound of the flashing, so that the best rescue opportunity will not be missed, and the normal use will not be affected.
