[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0025] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a heating deicing device, which includes a heating device 1, a pressure sensor 2, a pump 3, a control box 4, a thermometer 5, a solenoid valve group 6, a measuring device 7, a thermometer 2 8, a small water storage tank 9, a solenoid valve group 2 10 and a plurality of pipelines. The water source is sucked by the pump 3 and circulated through each part of the pipeline. The heating device 1 can heat the water in the pipeline in a short time to remove the ice residue remaining in the measuring device 7. The pressure sensor 2 is used to detect the pressure in the entire loop to ensure that it is at a stable value. The control box 4 is used to control the pump 3, the solenoid valve group 1 6, the solenoid valve group 2 10 and the display of the water temperature and pressure of the pipeline. The thermometer 1 5 and the thermometer 2 8 are used to detect the temperature of the water flow in the pipeline. The solenoid valve group 1 6 can be converted, that is, divided into the deicing period and the working detection period of the measuring device 7. The small water storage tank 9 stores part of the water for the overall internal circulation of the device. The solenoid valve group 2 10 can switch the entire device to external circulation and internal circulation. The heating deicing device provided by the present invention can effectively protect the marine measurement equipment 7 and extend its service life.

[0026] Furthermore, the heating device 1, the pressure sensor 2, the pump 3, the control box 4, the thermometer 1 5, the solenoid valve group 1 6, the measuring device 7, the thermometer 2 8, the small water storage tank 9, the solenoid valve group 2 10 and a plurality of pipelines form a loop to achieve the purpose of deicing the sea area measuring device 7. Since the pipelines are connected by joints, the measuring device 7 that needs to be deiced can be connected and replaced at any time.

[0027] Furthermore, the heating device 1 is a heating furnace, and the pipes are spirally passed through. The water flow in the pipes will raise the temperature to the required level in a very short time, and the circulating water melts the ice residue in the measuring device 7 at the corresponding temperature. The heating device 1 is a step-by-step heating device, and can automatically adjust the gear according to the actual temperature conditions.

[0028] Furthermore, the control box 4 includes an operation panel and an AC electrical interface. The operation panel is equipped with operation buttons, which can control the start and stop of the entire device, including emergency stop, reset, etc. The panel also includes an electronic screen for temperature display and pressure display. The entire device is connected to an external 220V AC power supply, and the AC line is distributed to the pump 3, the electromagnetic valve group 1 6, the electromagnetic valve group 2 10, and the heating device 1.

[0029] Furthermore, the thermometer 1 5 and the thermometer 2 8 are placed at the water inlet and outlet of the measuring device 7, respectively. The temperature difference before and after, as well as the temperature of the water flow in the pipeline can be calculated. When the measured temperature exceeds a certain range, the control box 4 can be used to adjust the heating device 1.

[0030] Furthermore, the solenoid valve group 6 is installed at the connection between the device and the measuring device 7, and the inlet and outlet of the measuring device 7 are controlled by the switch of the valve. When the measuring device 7 needs to be de-iced, the valve is switched to connect with the heating de-icing device. When the measuring device 7 needs to detect seawater, the valve is switched to connect with another pipeline to directly connect with the seawater to be detected.

[0031] Furthermore, the electromagnetic valve group 2 10 can switch the mode of the device, which can be divided into external circulation and internal circulation. In the initial stage of operation, the device is in external circulation and absorbs a certain amount of clean water. After running for a period of time and having a corresponding amount of water in the device, the control box 4 will automatically switch it to internal circulation, which can quickly increase the water flow temperature and ensure the loss of heat.

[0032] Furthermore, the small water storage tank 9 is used to store a corresponding amount of water to ensure that the device can continue to operate during internal circulation until the deicing is completed.

[0033] Furthermore, the device as a whole will be directly welded to the bottom of the ship's hold.

[0034] It also includes the following usage process:

[0035] Power the entire device, turn the "power switch" knob to the vertical position on the operation panel of the control box 4, and the device can be operated. First, the knob can be turned to "de-icing", that is, the device enters the de-icing mode. Press the "pump switch" button, and the pump 3 starts working. Press the button again and the pump 3 stops working. Then press the "heating" button to start the heating device 1. During the operation of the device, the temperature displayed on the display can be observed. When the temperature exceeds the range, the controller will automatically adjust the heating device 1 until the temperature returns. After running for a period of time, the control box 4 will automatically control the solenoid valve group according to the time relay, so that the device enters the internal circulation mode until the de-icing work is completed, and then switch it to the external circulation mode again.

[0036] After the de-icing work of the measuring device 7 is completed, the knob is turned to "measurement", that is, the inlet and outlet of the measuring device 7 will be directly switched to connect with the detected seawater. At this time, the control box 4 will directly cut off the power supply of the pump 3 to avoid the operator's mistaken pressing, causing it to start idling, and even reducing its service life.

[0037] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
