본 고안은 콘크리트 믹서 트럭에서 드럼세척용 물을 저장하는 물탱크의 동결방지장치에 관한 것이다.The present invention relates to a freezing prevention device of a water tank for storing drum washing water in a concrete mixer truck.
콘크리트에 동결방지제 등을 혼합하면 영하로 기온이 급강하하는 동절기에도 양생시킬 수 있어 작업현장까지 콘크리트를 실어나르는 믹서 트럭은 외부기온이 낮은 상태에서도 운행을 하고 있다. 이러한 믹서 트럭에는 드럼내의 콘크리트를 현장에서 모두 배출시킨 후 드럼내에 붙어 있는 몰탈 등의 잔유물을 씻어내어야 하는데 이를 위해 드럼 전방에는 물탱크가 설치되어 있다.Mixing the anti-freeze agent with concrete can cure even in winter when the temperature drops sharply below freezing, so the mixer truck that carries concrete to the work site operates even when the outside temperature is low. In the mixer truck, all the concrete in the drum is discharged from the field, and then the residues such as mortar and the like stuck in the drum need to be washed out. For this purpose, a water tank is installed in front of the drum.
그러나 이러한 물탱크에는 통상 동결방지장치 혹은 수단을 강구하지 않고 있기 때문에 동절기에 저온으로 내려가면 물탱크내의 물이 얼어 물탱크가 파열되는 등의 문제를 안고 있었다.However, such a water tank usually does not have a freeze protection device or means, so when the temperature is lowered in winter, the water in the water tank freezes, causing the water tank to burst.
본 고안의 목적은 동절기에 물탱크가 동결되는 것을 방지하기 위한 장치를 제공하는데 있는 것이다.An object of the present invention is to provide a device for preventing the water tank is frozen in winter.
본 고안은 상기 목적을 달성하기 위하여, 물탱크내에 팬과 수온감지 스위치를 설치하고 팬은 물탱크내에서 수류를 조성하도록 하며 이 팬을 릴레이 작동에 의하여 밧데리의 전원이 인가되도록 하고 릴레이는 수온감지 스위치가 물탱크의 저수온(低水溫)을 감지할 때 접속하여 도전(출력)되도록 한 것이다.In order to achieve the above object, the present invention provides a fan and a water temperature sensing switch in the water tank, and the fan creates a water flow in the water tank, and the fan is applied to power the battery by relay operation, and the relay detects the water temperature. When the switch senses the low water temperature of the water tank, it is connected and made to conduct (output).
이하 본 고안의 실시예를 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.
제1도는 믹서 트럭에서 드럼(1) 전방에 설치되는 물탱크(2)내에 팬(3)과 수온감지 스위치(4)가 설치된 상태를 예시한 것으로서, 팬(3)은 제2도와 같이 물이 적정수위로 채워진 높이에서 회전하여 물탱크(2)내의 물을 출렁이게 하면서 일방향으로 소용돌이 수류를 이루도록 한 것이다. 수온감지 스위치(4)는 물탱크(2)내의 수온이 빙점이하로 내려가면 접속상태를 이루도록 한 것으로 입력 단자는 이그니션 키(5)를 거쳐 밧데리의 양단자에 연결된다.FIG. 1 illustrates a state in which a fan 3 and a water temperature sensing switch 4 are installed in a water tank 2 installed in front of a drum 1 in a mixer truck. Rotation at the height filled with the appropriate level to make the water in the water tank (2) to achieve a whirlpool flow in one direction. The water temperature sensing switch 4 is configured to be connected when the water temperature in the water tank 2 falls below the freezing point. The input terminal is connected to both terminals of the battery via the ignition key 5.
상기 팬(3)의 입력단자와 수온감지 스위치(4)의 출력단자 및 밧데리(6)의 양단자 사이에는 릴레이(7)가 설치된다. 이 릴레이(7)는 코일측에 수온감지 스위치(4)의 출력단자가 연결되고, 단자의 양쪽에 팬(3)의 입력단자와 밧데리(6)의 양단자가 연결되어 있다.A relay 7 is installed between the input terminal of the fan 3, the output terminal of the water temperature sensing switch 4, and both terminals of the battery 6. The relay 7 has an output terminal of the water temperature sensing switch 4 connected to the coil side, and an input terminal of the fan 3 and both terminals of the battery 6 are connected to both terminals.
따라서 일단 시동되기 전 상태에서도 이그니션 키(5)가 접속되어 있는 상태에서는 본 고안의 장치가 수온에 따라 자동적으로 작동한다.Therefore, the device of the present invention operates automatically according to the water temperature in the state in which the ignition key 5 is connected even in the state before starting.
즉, 물탱크(2)내의 물이 저수온(빙점이하)으로 내려가면 수온감지 스위치(4)가 접속되어 릴레이(7)의 코일에 전류를 인가해 코일이 자화되면 그 여자력으로 접점을 접속상태로 만들고 이에 따라 밧데리(6)의 전류가 팬(3)(실제로는 팬을 구동시키는 모터)에 흘러 팬(3)을 구동시키므로서, 물탱크(2)내의 물이 출렁이면서 회전하여 쉽게 동결되지 않는다.That is, when the water in the water tank 2 falls to the low water temperature (below the freezing point), the water temperature sensing switch 4 is connected, and a current is applied to the coil of the relay 7, and the magnetization of the coil connects the contact with the excitation force. The current in the battery 6 flows into the fan 3 (actually the motor driving the fan) to drive the fan 3, so that the water in the water tank 2 rotates and freezes easily. Do not.
이와 같은 본 고안은 동절기(혹한기)에 믹서 트럭의 출발지에서 도착지까지의 사이, 특히 출발대기시나 도착대기시 또는 콘크리트의 배출시에 정체되어 있는 물탱크내의 물이 얼지 않도록 해 주므로서, 물탱크의 동파나 믹서의 세척이 조기에 이루어지지 않으므로서 발생되는 여러문제를 미연에 방지하게 되는 등의 효과가 있는 것이다.This invention prevents the water in the water tank stagnating from the start to the end of the mixer truck during the winter season (cold season), especially during the start wait, arrival wait or when the concrete is discharged. It is effective in preventing various problems caused by not washing the freezing wave or the mixer at an early stage.
