Further, the sewage draining outlet comprises a gutter opening and closing shaft 7-1 and a gutter opening and closing plate 7-2, the gutter opening and closing shaft 7-1 drives the gutter opening and closing plate 7-2 to be opened or closed, the gutter opening and closing shaft 7-1 is driven by a motor, and the motor is arranged in the house gutter 2. Thereby realizing the opening and closing functions of the sewage draining outlet.

As shown in fig. 19, a, b, c, d are all parameter variables, and are used for distinguishing different situations in the comprehensive analysis, for example: when a =0 and c =0, there is a high probability of a winter icing condition, and the "electromagnetic heating" section can be activated accordingly; when b =1 and d =0, the sludge is too thick and still needs to be cleaned, although the time requirement is not met. The two situations are only used as examples, and the corresponding algorithm and decision mode can be optimized and optimized according to different situations in the practical invention;

the central processing unit of the circuit part comprehensively analyzes the signals and judges related problems, including but not limited to the following: whether the cleaning cycle is close to, whether the cleaning cycle is difficult in winter, and the amount of the sludge.

For the timer part, assuming that the cleaning period is T, the time from the last cleaning is T, and let X = (T-T)/T, that is, the time ratio to the next cleaning at this time, when this ratio is too small, it can be considered that the cleaning period is close; the allowable value of the above ratio is Y, and when X > Y, let b = 1; let b =0 when X < Y; when X =0, namely reaching the cleaning cycle, forcibly cleaning;

for the conductivity sensor part, the possible thickness of the sludge is judged according to the different conductivity of different parts of the detection cross bar, and the schematic diagram is shown in figure 20.

The temperature sensor may be of any type, including but not limited to: the brand is Songtuan, and the model is WZP-187-3 PBO.

The humidity sensor may be of any type, including but not limited to: the brand is wonderful Xin, and the model is TH 10S-B.

The timer may be of any type, including but not limited to: the brand is Omron, model number H7E.

The detection rotary rod 9-2 can adopt a conductivity sensor, and a plurality of sensors are arranged at different parts of the detection cross rod to capture conductivity information of corresponding depth so as to analyze the sludge depth; the conductivity sensor model includes but is not limited to: the brand is REMOND AOTO, model number RMD-ISEC 2.

The central processing unit can adopt any equipment capable of running the process program, such as a single chip microcomputer or a computer, and the like, and the equipment comprises but is not limited to: a single chip microcomputer with the brand name of Risym and the model number of STC89C52 RC-40I.

The motor may be of any type, including but not limited to: the brand is CHENGX, and the model is a 5A speed regulator.

In a preferred scheme, the cleaning method of the roof gutter self-cleaning device comprises the following steps:

the method comprises the following steps: the temperature sensor and the humidity sensor respectively collect temperature and humidity signals, a temperature value area is divided to distinguish winter and summer, and the humidity condition around the house gutter 2 is judged according to the humidity value; the conductivity sensor is used for detecting the sludge depth; the sensor transmits different signals of the external environment, the sludge and other factors to the central processor, so as to control different mechanical parts and realize corresponding functions.

Step two, the detection vertical rods 9 move in the house gutter 2 regularly, a timer can be arranged at intervals of the detection vertical rods 9 to calculate the time from the last cleaning, and after the sediment is detected by the conductivity sensor, the motors 4-5 in the fixed ends are started to drive the U-shaped scrapers 5 to slide, so that the sediment is peeled from the inner wall of the house gutter 2; meanwhile, when the climate meets the winter condition, the electromagnetic heating part is started, and when the climate does not meet the winter condition, the electromagnetic heating part is not started;

step three, after the U-shaped scraper 5 reciprocates once or for a plurality of times, the sludge is peeled off, then the sludge moves to the position right below the pushing baffle plate 6, the pushing baffle plate clamping groove 6-2-3 is pushed, and the pushing baffle plate clamping groove 6-2-3 is connected with the clamping groove 3-2-2;

and step four, the U-shaped scraper 5 drives the pushing and blocking panel 6 to move towards the sewage discharge outlet, meanwhile, the gutter opening and closing plate 7-2 is opened, and the pushing and blocking panel 6 discharges the sludge.

The operating principle that can be realized by the circuit part of the invention (for convenience of description, the components of the device are classified into five categories of A, B, C, D, E) is as follows:

A. temperature sensor, humidity sensor, timer, central processing unit and the like on roof of house

B. A detection part: motor on two sides, motor of central rotor and conductivity sensor

C. A scraper part: electric motor in end opening of sliding rod and electromagnet in scraper main body

D. A baffle portion: top motor

E. Opening and closing the gutter: internal electric machine

The circuit arrangement may take the following scheme:

arranging a main power supply (a solar storage battery or a direct connection with a power supply in a house) at A; b, C all slide on the gutter, so a long wire can be directly led out to the position A; because D is far away and needs to move vertically, the storage battery and the wireless receiving device (the wireless receiving device is used for receiving signals sent by the central processing unit) can be separately arranged in the storage battery; since E is located inside the gutter, the wire can be directly laid inside the gutter and led out to a.

Furthermore, both the B, C, D and the gutter are designed with hollow structures for routing arrangement of various circuits; moreover, according to the structural introduction, B and C need to be designed with hollow structures in the whole part, D only needs to be designed with hollow structures at the top, and the gutter needs to be designed with hollow structures from the opening and closing position to the roof of the house.
