Description

Technical Field

[0001] The utility model relates to the technical field of tank heaters, in particular to a tank heater state monitoring device. Background Art

[0002] The normal operating temperature of the engine of heavy vehicles such as tanks (infantry fighting vehicles) needs to be maintained between 70-90 degrees. Too low a temperature will lead to incomplete combustion of diesel and insufficient engine power. At the same time, too low a temperature will also cause the gap between engine parts to become smaller, the friction resistance to increase, and the power of the tank to move will be greatly reduced. In cold weather, in order to make the engine reach the normal operating temperature, the heater must be used to preheat the engine in advance when starting. The tank heater is generally put into operation when the outside temperature is below 5 degrees Celsius. The heater uses coolant as a heat carrier and realizes the tank heating process through the tank's circulation system.

[0003] The tank heater mainly consists of a combustion chamber, a heating pot body, a coolant channel and other components. When working, the combustion chamber is fed with diesel fuel for combustion through the oil circuit. The combustion of diesel fuel in the combustion chamber increases the temperature of the coolant in the heating pot body. The heated coolant is transported to the tank's engine water jacket, water radiator, electric pre-lubricating pump water channel, and oil tank serpentine water pipe through the coolant channel for heating, and then flows back to the heating pot body of the heater for heating again. This cycle completes the preheating of the tank. The coolant channel of the tank heater works in a closed state. In reality, due to various reasons, the coolant may not flow smoothly due to the presence of foreign matter in the coolant channel, or the coolant channel may be blocked due to the presence of air in the coolant channel. Both situations will prevent the coolant from flowing normally, causing the tank heater's heating pot body to "burn dry". The local temperature of the heating pot body can reach 1600 degrees Celsius, while the melting point of metal begins to melt at about 1200 degrees Celsius, thus causing the tank heater's heating pot body to burn out. Therefore, it is necessary to develop corresponding devices to solve the above-mentioned technical problems existing in tank heaters. Utility Model Content

[0005] The technical solution of the utility model is: the tank heater status monitoring device of the utility model has the following structural features: it includes a flow meter connected in series to the coolant channel of the heating pot body of the tank heater for detecting the real-time flow of the coolant in the coolant channel, a solenoid valve connected in series to the oil inlet pipe of the combustion chamber of the tank heater for controlling the on and off of the diesel input to the combustion chamber, a sound and light alarm fixedly arranged in a position convenient for the driver to observe in the tank driving cabin for outputting sound and light alarm signals when the flow of the coolant flowing in the coolant channel is abnormal, and a monitor fixedly arranged in a position convenient for the driver to observe in the tank driving cabin for controlling the closing of the solenoid valve to cut off the diesel input to the combustion chamber and controlling the sound and light alarm to alarm when the flow detected by the flow meter is abnormal.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] (Example 1)

[0018] See Figure 1 and Figure 2 The tank heater status monitoring device of this embodiment is mainly composed of a flow meter 1, a solenoid valve 2, an audible and visual alarm 3, a monitor 4 and a control switch 5.

[0019] The flow meter 1 is connected in series to the coolant channel 104 of the heating pot body 103 of the tank heater, and is used to detect the real-time flow of the coolant in the coolant channel 104. The flow meter 1 is a commercially available part, and has a detection signal output terminal.

[0020] The solenoid valve 2 is connected in series to the oil inlet pipe 102 of the combustion chamber 101 of the tank heater, and is used to control the on-off of the diesel fuel for combustion and heating input into the combustion chamber 101. The solenoid valve 2 is a commercially available normally open solenoid valve. The solenoid valve 2 has a control signal input terminal.

[0021] The sound and light alarm 3 is fixedly arranged in a place in the tank driving compartment where the driver can easily observe. The sound and light alarm 3 is used to output a sound and light alarm signal when the flow rate of the coolant flowing in the coolant channel 104 is abnormal, so that relevant personnel can make corresponding processing and operations in time. The sound and light alarm 3 is a commercially available part.

[0022] The monitor 4 is fixedly installed in a place in the tank driving cabin where the driver can easily observe it. The monitor 4 is used to control the action of the solenoid valve 2 according to the flow signal detected by the flow meter 1. When the real-time flow of the coolant detected by the flow meter 1 is lower than the set value, the monitor 4 controls the solenoid valve 2 to close to cut off the supply of diesel from the combustion chamber oil inlet pipe 102 to the combustion chamber 101, thereby solving the technical problem of the heating pot body 103 being damaged due to dry burning in the prior art; at the same time, the monitor 4 controls the sound and light alarm 3 to send out a sound and light alarm signal.

[0023] As a specific implementation, in this embodiment, the monitor 4 includes a housing 41; a display screen 42 fixed on the housing 41 for displaying information parameters including the real-time flow rate of the coolant in the coolant channel 104 for the driver to observe; a main control module 43 fixed in the housing 41 for the main control of the monitor 4; a signal processing module 44 fixed in the housing 41 and electrically connected to the detection signal output end of the flow meter 1 for converting the detection signal of the flow meter into a signal that can be processed by the main control module 43; an execution module 45 fixed in the housing 41 and electrically connected to the control signal input end of the solenoid valve 2 for correspondingly controlling the on and off of the solenoid valve 2 according to the instruction of the main control module 43; and a power supply module 46 for providing working power to the monitor 4. The display screen 42, the signal processing module 44 and the execution module 45 are all electrically connected to the main control module 43. The execution module 45 can adopt a relay. It should be particularly noted that the structures and working principles of the main control module 43, the signal processing module 44 and the execution module 45 are mature existing technologies and are not described in detail.

[0024] The control switch 5 is preferably arranged in a place in the tank driving compartment where the driver can operate it easily; the control switch 5 can control the action of the solenoid valve 2 and the sound and light alarm 3 to sound and light alarm at the same time through manual operation by the driver. The control switch 5 is a redundant backup to increase reliability. When the monitor 4 automatically controls the solenoid valve 2 and the sound and light alarm 3 and fails, the driver can manually operate the control switch 5 according to the real-time flow value of the coolant observed on the display screen 42 of the monitor 4 and when an abnormality is found, so that the solenoid valve 2 cuts off the oil supply and the sound and light alarm 3 alarms. The control switch 5 is electrically connected to the solenoid valve 2 and the sound and light alarm 3 respectively.

[0025] The working principle and process of the tank heater status monitoring device of this embodiment are briefly described as follows:

[0026] When the tank engine needs to be preheated, the tank heater is started to work, and the diesel is input into the combustion chamber 101 through the oil inlet pipe 102 and the solenoid valve 2 of the device to burn and heat the heating pot body 103. After the coolant as the heat transfer medium is heated, it circulates and flows through the coolant channel 104 to heat the engine. The flow meter 1 connected in series to the coolant channel 104 detects the current coolant flow in the coolant channel 104 in real time and sends the detected signal to the monitor 4. The monitor 4 processes the received signal in real time (that is, compares the real-time detection value with the set threshold value, which is the prior art). When it is found that the coolant flow is lower than the set value, the monitor 4 automatically controls the normally open solenoid valve 2 to close to cut off the oil supply to the combustion chamber 101, thereby stopping the heating of the heating pot body 103, thereby preventing the heating pot body 103 from being damaged by dry burning due to continued heating; at the same time, the sound and light alarm 3 is controlled to send an alarm signal. When it is needed to control the switch 5, its working principle and process are as mentioned above, and no further description is needed.

[0027] As can be seen from the foregoing, the tank heater status monitoring device of this embodiment has a relatively simple structure, is easy to install in the tank, has a low cost, and has reliable working performance, but it can effectively solve the problem of dry burning damage caused by debris or air blockage in the pipeline that is prone to occur in the heating pot body 103 of the tank heater in the prior art, thus filling the gap in the prior art.

[0028] The above embodiments are descriptions of specific implementation methods of the present invention, rather than limitations of the present invention. Technical personnel in the relevant technical field can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
