Description

Technical Field

[0001] The invention relates to the fields of environmental protection technology and fog cannons, and in particular to an antifreeze type energy-saving fog cannon. Background Art

[0002] The fog cannon is a common environmental protection equipment, which is mainly used to remove and purify dust in the air. The fog cannon includes a base, a water tank located inside the base, a water pump connected to the water tank, a mounting frame located on the top of the base, and a wind tube rotatably mounted on the mounting frame. The wind tube includes an atomizing nozzle and a fan installed inside the wind tube. The atomizing nozzle is connected to the water pump through a water supply pipe. The water pump transports the water inside the water tank to the atomizing nozzle and atomizes it by blowing strong wind through the fan.

[0003] For example, application number CN202221316378.9 relates to a dust removal fog cannon, belonging to the field of environmental protection technology, which includes a base, a wind tube, a water supply pipe, and a plurality of fixings for mounting the water supply pipe on the wind tube, wherein the fixing is provided with a through hole for the water supply pipe to pass through, and the through hole is provided with protective cotton, and the protective cotton abuts against the water supply pipe. This application has the effect of reducing the risk of shaking of the water supply pipe.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment can solve the problem that the water supply pipe is usually hung freely on the wind tube when used, and because the fog cannon is generally placed outdoors, when there is wind, the water pipe will swing, which will easily cause the connection between the water pipe and the atomizing nozzle to disconnect, and there is currently no better limiting structure to limit the water pipe.

[0034] Example 2: Figures 4 to 6 As shown, on the basis of Example 1, an antifreeze energy-saving fog cannon provided by the present invention further includes: an electric heating wire 61 distributed in a spiral is also provided in the insulation sleeve 6. There are multiple electric heating wires 61; this embodiment adopts three electric heating wires distributed in parallel. And the two ends of the electric heating wire 61 are respectively connected with a positive electrode sleeve 62 and a negative electrode column 63; wherein, the positive electrode sleeve and the negative electrode column are made of conductive materials. The positive electrode sleeve 62 of the electric heating wire in the insulation sleeve 6 is connected to the negative electrode column 63 of the electric heating wire in the adjacent insulation sleeve 6; the purpose of such a setting is to facilitate the formation of head-to-tail connection of multiple insulation sleeves while ensuring the normal operation of the electric heating wires in the connected insulation sleeves. At the same time, preferably, a battery can be installed on the base or the support plate or a cable can be used to connect the external power supply to realize the power supply demand of the fog cannon. A first temperature detection sensor 17 is also provided on the support plate 5 for real-time detection of the external cold environment. The electric heating wire 61 is connected to a second temperature detection sensor 18; used to achieve precise temperature control of the electric heating wire. A controller 19 with an embedded structure is also provided on one side of one of the thermal insulation sleeves. Specifically, the controller is arranged on the outer wall of the outermost distribution thermal insulation sleeve.

[0035] Among them, the controller 19 is connected to the electric heating wire 61, the first temperature detection sensor 17 and the second temperature detection sensor 18 respectively. The controller 19 includes a signal receiving module 191, a signal preprocessing module 192, an algorithm processing module 193, and a command execution module 194. The signal receiving module 191 is used to receive the temperature parameter signal of the current environment detected by the temperature detection sensor; the signal preprocessing module 192 is used to use mean filtering to preprocess the temperature parameter signal of the signal receiving module to smooth the data so as to improve the accuracy and consistency of the real-time temperature detection of the outside world. The algorithm processing module 193 is used to use a proportional-integral-differential controller to adjust the heating temperature of the electric heating wire, which can be adjusted according to the difference between the front-end initialization mode setting value and the real-time detection temperature of the rear-end first temperature detection sensor.

At this time, if the first temperature detection sensor detects that the outdoor environment is 4°C, the electric heating wire will not be started to control the heating of the water delivery pipe. If the first temperature detection sensor detects that the outdoor environment is 3°C, since 3-T1(2)=1; the heating and heat preservation control process of the water supply pipe can be started at this time; that is, the outdoor environment temperature is 1-3°C and the heating starts; and the corresponding output m(t) has a temperature adjustment amount of 2, that is, the electric heating starts to control the heating temperature of the insulation sleeve to 2°C, and the number of electric heating wires used is 1, that is, the corresponding first-level dynamic output unit controls the set temperature of the second temperature detection sensor to be 2°C. The second-level heating unit 202 is defined as the state when the difference between the initialization mode setting value T2 at the front end and the real-time temperature detection of the first temperature detection sensor at the rear end is greater than M1 and less than M2; and in this state, the output m(t) value of the algorithm processing module is moderate; for example, the initial setting of the T1 parameter of the fog cannon is 2°C, and when M2 is set to 5, the difference is between 1 and 5, and the preferred setting parameter is 3. At this time, if the first temperature detection sensor detects that the outdoor environment is 4°C, the electric heating wire will not be started to heat the water supply pipe. If the first temperature detection sensor detects that the outdoor environment is -1°C, the heating and insulation control process of the water supply pipe can be started at this time; that is, the outdoor environment temperature is -3 to -1°C and the secondary heating starts; and the corresponding output m(t) has a temperature adjustment amount of 3, that is, the electric heating starts to control the heating temperature of the insulation sleeve to 3°C, and the number of electric heating wires used is 2, that is, the corresponding secondary dynamic output unit controls the set temperature of the second temperature detection sensor to 3°C. The three-level heating unit definition 203 is the state when the difference between the current end initialization mode setting value T3 and the real-time temperature detection of the rear end first temperature detection sensor is greater than M2 and less than M3; and in this state, the output m(t) value of the algorithm processing module is the largest. The corresponding output m(t) has a temperature adjustment amount of 5, that is, the electric heating starts to control the heating temperature of the insulation sleeve to be not less than 5°C, and the number of electric heating wires used is 3, that is, the corresponding three-level dynamic output unit.
