Description

Technical Field

[0001] This utility model relates to the field of heater maintenance technology, and in particular to a heater maintenance device. Background Technology

[0002] A heater is a device that uses electrical energy or other energy sources to generate heat to raise the temperature of fluids (such as air, water, etc.). It is widely used in industrial and domestic fields. Its core component, the heat exchange tube, is a key element for achieving effective heat transfer. It is usually made of materials with good thermal conductivity, such as metals. Through special design, the contact area with the fluid is increased to efficiently transfer heat from inside the tube to the fluid outside the tube. Heat exchange tubes come in various shapes, including straight tubes and coils. They have a compact structure and can complete a large amount of heat exchange in a limited space, ensuring the heater works stably and efficiently. They provide reliable protection for various scenarios that require temperature control. When a heater malfunctions, it is often necessary to repair it.

[0003] In existing technologies, people mostly use multimeters to check and repair the heater's circuitry. While this method can identify some circuit system faults, it cannot identify faults in the heater's piping system. Workers often have to rely on visual inspection of the appearance and water flow to check for pipe faults. However, this method of pipe inspection suffers from low accuracy, high error rate, and excessive reliance on the worker's experience. Furthermore, when scale buildup and blockages are found in the pipes, workers often need to use a pipe brush to clean them, which is inefficient and ineffective.

[0004] Therefore, there is an urgent need to provide a heater maintenance device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a heater maintenance device.

[0006] To solve the above-mentioned technical problems, the present invention provides a heater maintenance device, including a maintenance platform mechanism and a pipeline detection mechanism. A circuit detection mechanism for detecting voltage and current is welded and fixed on the maintenance platform mechanism, and a pipeline detection mechanism for detecting medium flow is fixed inside the circuit detection mechanism.

[0007] A cleaning mechanism is welded and fixed onto the maintenance platform mechanism;

[0008] The inspection platform mechanism is equipped with a collection mechanism for collecting cleaning fluid.

[0009] The present invention is further configured such that: the maintenance platform mechanism includes a platform body, an insulating pad is bonded and fixed on the platform body, a maintenance plate is also fixed on the platform body, a storage drawer is slidably arranged on the platform body, a slot is opened on the platform body, an installation groove is also opened on the platform body, and a cover plate is hinged to the installation groove.

[0010] Through the above technical solution, the insulating pad can improve the insulation of the device's table surface, the storage drawer can store inspection lines, inspection pipelines and welding machines and other maintenance equipment, and when the cover is closed, the cover and the table surface of the main body can form a flat working platform on which the staff can inspect and maintain the heater.

[0011] The present invention is further configured such that: the circuit detection mechanism includes a housing welded to the main body of the platform, a control panel is embedded and fixed on the housing, a detection circuit board is fixed on the inner side of the housing, a detection interface is fixed on the housing, a display screen is embedded and fixed on the housing, and a control motherboard is fixed inside the housing.

[0012] The above technical solution uses a stainless steel casing and a control panel with multiple control buttons. The detection circuit board has the same structure as the detection circuit of a smart multimeter. The detection circuit board is electrically connected to the detection interface and the detection circuit board. When the operator plugs the detection wire into the corresponding detection interface, the device can be used to detect the voltage, current, resistance, capacitance, and breakpoints of the heater circuit or components. The detection results will be displayed on the screen, which facilitates the operator to detect and judge the cause of the heater malfunction. The control motherboard is equipped with a processor, memory, and other components, which can compare and calculate the detection results with the set values ​​and store the detection data.

[0013] The present invention is further configured such that: the pipeline detection mechanism includes a mounting plate fixed to the inner side of the housing, a liquid pump is fixed on the mounting plate, a connector is sealed to the liquid pump, a gas pump is also fixed on the mounting plate, and a filter cover is fixed to the air inlet end of the gas pump.

[0014] Through the above technical solution, the input end of the liquid pump is connected to an external water source, and its connector is a quick-connect connector that can be connected to the liquid detection pipeline. The gas pump is equipped with the same connector structure as the liquid pump, which can be connected to the gas detection pipeline. The filter cover can effectively prevent the gas pump from sucking in foreign matter.

[0015] The present invention is further configured such that: a test gauge is fixed on the mounting plate, the test gauge is sealed with a liquid inlet, the test gauge is also sealed with an air inlet, and the test gauge is also sealed with a liquid outlet.

[0016] The above technical solution incorporates gas and liquid flow rate sensors within the detector, enabling the detection of liquid and gas flow rates. Operators connect the heat exchange pipeline inlet of the heater to a liquid or gas pump via a detection tube, and connect the medium outlet to the detector's liquid or gas inlet. Turning on the liquid or gas pump allows it to pump gas or liquid media into the heater's heat exchange pipeline at a specified power. The media then reaches the detector, which detects the outflow velocity and flow rate, transmitting the data to the control board. The processor compares the velocity and flow rate with standard values ​​to determine if there is excessive scale buildup, poor flow, or blockage in the pipeline. Because the device has both gas and liquid detection pipelines and mechanisms, it is suitable for heaters with gas-to-gas or liquid-to-liquid heat exchange, as well as those with gas-to-liquid heat exchange. The outlet is connected to a collection mechanism, allowing wastewater to be discharged into a wastewater tank.

[0017] The present invention is further configured such that: the cleaning mechanism includes a cleaning tank fixed inside the mounting groove, a plurality of ultrasonic transducers are fixed on the inner bottom wall of the cleaning tank, an inlet pipe is also embedded and fixed on the mounting groove, and an electronic valve is also fixed on the inlet pipe.

[0018] With the above technical solution, clean water is connected to the inlet pipe. When the staff uses the device to detect that there is a blockage or poor flow in the heat exchange medium pipeline of the heater, it indicates that there is a lot of scale buildup in the pipeline. At this time, the staff can remove the heat exchange pipeline of the heater, open the cover plate to expose the cleaning tank, and open the electronic valve by switching on the switch. Water will be injected into the cleaning tank through the inlet pipe. When the water depth is sufficient, the staff closes the electronic valve and puts the heat exchange pipeline into the cleaning tank. Then, the ultrasonic transducer is turned on. At this time, the ultrasonic transducer generates ultrasonic waves, producing cavitation and direct flow effects to clean the scale buildup in the heat exchange pipeline. After cleaning, the staff can take out the heat exchange pipeline and reconnect the heat exchange pipeline to the liquid pump connector and the liquid inlet of the test gauge. The liquid pump is then turned on to clean the scale that has been detached from the pipeline. The wastewater generated during cleaning will also enter the sewage tank.

[0019] The present invention is further configured such that: the collection mechanism includes a sewage tank fixed to the bottom wall inside the platform body, a sewage tank is welded and fixed to the sewage tank, a drain pipe is threadedly connected to the platform body, an air valve is fixed to the sewage tank, a drain valve is fixed to the sewage tank, and multiple casters are welded to the bottom end of the sewage tank.

[0020] With the above technical solution, the drain pipe is a flexible hose, and the top of the drain pipe is connected to the drain port of the cleaning tank. When the staff uses the device to clean the heat exchange pipeline, they can open the drain switch. At this time, the cleaning liquid in the cleaning tank will flow into the sewage tank through the drain pipe. When the cleaning liquid needs to be discharged, the staff can remove the sewage tank and move it to the designated position using casters, and then discharge the sewage through the drain valve. This avoids direct discharge of sewage and helps to keep the environment clean and tidy. The air valve can effectively balance the air pressure inside and outside the sewage tank and prevent the water inlet and outlet from being blocked.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up a repair bench mechanism, a circuit testing mechanism, and a pipeline testing mechanism, this utility model enables the device to perform both circuit testing and repair of the heater and pipeline testing and repair of the heater, effectively improving the practicality of the device.

[0023] 2. By setting up an inspection platform mechanism, a cleaning mechanism, and a collection mechanism, this utility model provides a flat working platform when the heater is being inspected and the circuit is being repaired. When the heater pipeline needs to be cleaned, the cover can be lifted to expose the cleaning mechanism, which improves the flexibility of use and reduces the size of the device.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-6A heater maintenance device includes a maintenance platform mechanism 1 and a pipeline inspection mechanism 3. The maintenance platform mechanism 1 includes a platform body 101, an insulating pad 102 is adhered and fixed to the platform body 101, a maintenance plate 103 is also fixed to the platform body 101, a storage drawer 104 is slidably disposed on the platform body 101, a slot 105 is formed on the platform body 101, and a mounting groove 106 is formed on the platform body 101. A cover plate 107 is hinged to the mounting groove 106. The insulating pad 102 can... This improves the insulation of the device's work surface. The storage drawer 104 can store maintenance equipment such as testing lines, testing pipelines, and welding machines. When the cover 107 is closed, the cover 107 and the work surface of the platform body 101 form a flat working platform, allowing workers to inspect and repair the heater. A circuit testing mechanism 2 for detecting voltage and current is welded and fixed to the maintenance platform mechanism 1. The circuit testing mechanism 2 includes a housing 201 welded to the platform body 101. The housing 201 is fitted with a control panel 202. A detection circuit board 203 is also fixed inside the housing 201. A detection interface 204 is also fixed on the housing 201. A display screen 205 is also fitted on the housing 201. A control motherboard 206 is also fixed inside the housing 201. The housing 201 is made of stainless steel. The control panel 202 has multiple control buttons. The detection circuit board 203 has the same detection circuit structure as a smart multimeter. The detection circuit board 203 is electrically connected to the detection interface 204 and the detection motherboard 206. When the operator plugs the detection wire into the corresponding detection interface 204, the device can be used to detect the voltage, current, resistance, capacitance, and breakpoints of the heater circuit or components. The detection results will be displayed on the display screen 205, facilitating the operator's detection and judgment of the heater's fault causes. The control motherboard 206 is soldered with a processor, memory, and other components. It can compare and calculate the detection results with the set values ​​and can also store the detection data.

[0033] like Figure 1 and Figure 4As shown, the circuit testing mechanism 2 has a pipeline testing mechanism 3 for detecting the flow rate of the medium fixed inside. The pipeline testing mechanism 3 includes a mounting plate 301 fixed inside the housing 201, a liquid pump 302 fixed on the mounting plate 301, a connector 303 sealed to the liquid pump 302, a gas pump 304 fixed on the mounting plate 301, a filter cover 305 fixed to the air inlet end of the gas pump 304, and a gauge 306 fixed on the mounting plate 301. The gauge 306 has a liquid inlet 307 sealed to it. The measuring instrument 306 is also sealed with an air inlet 308 and a liquid outlet 309. The input of the liquid pump 302 is connected to an external water source, and its connector 303 is a quick-connect fitting that can be connected to a liquid detection pipeline. The gas pump 304 has the same connector 303 structure as the liquid pump 302 and can be connected to a gas detection pipeline. The filter cover 305 effectively prevents the gas pump 304 from sucking in impurities. The measuring instrument 306 contains gas and liquid flow rate sensors, capable of detecting liquid flow. The device controls the flow rate and velocity of the gas and fluid. Operators can connect the medium inlet of the heater's heat exchange pipeline to the connector 303 of the liquid pump 302 or gas pump 304 via the detection tube, and connect the medium outlet to the liquid inlet 307 or gas inlet 308 of the detection gauge 306. Then, the liquid pump 302 or gas pump 304 is turned on. At this time, the liquid pump 302 or gas pump 304 will pump the gas or liquid medium into the heater's heat exchange pipeline at a specified power. After passing through the heat exchange pipeline, the medium reaches the detection gauge 306, where it is detected. Table 306 can detect the outflow velocity and flow rate of the medium and transmit the data to the control motherboard 206. The processor compares the velocity and flow rate with the standard values ​​to determine whether there is excessive scale buildup, poor flow, or blockage in the pipeline. Since the device is equipped with two sets of detection pipelines and detection mechanisms for gas and liquid, it can be used for heaters with gas-to-gas heat exchange, liquid-to-liquid heat exchange, and gas-to-liquid heat exchange. The liquid outlet 309 is connected to the collection mechanism 5, so that wastewater can be discharged into the sewage tank 501.

[0034] like Figure 1 and Figure 5As shown, a cleaning mechanism 4 is welded and fixed to the maintenance platform mechanism 1. The cleaning mechanism 4 includes a cleaning tank 401 fixed inside the mounting groove 106. Multiple ultrasonic transducers 402 are fixed to the inner bottom wall of the cleaning tank 401. An inlet pipe 403 is also embedded and fixed to the mounting groove 106. An electronic valve 404 is also fixed to the inlet pipe 403. Clean water is connected to the inlet pipe 403. When the operator uses the device to detect that there is a blockage or poor flow in the heat exchange medium pipeline of the heater, it indicates that there is a lot of scale in the pipeline. At this time, the operator can remove the heat exchange pipeline of the heater, open the cover plate 107 to expose the cleaning tank 401, and open the electronic valve 404 by the switch. 4. Water will be injected into the cleaning tank 401 through the inlet pipe 403. When the water depth is sufficient, the operator closes the electronic valve 404 and puts the heat exchange pipeline into the cleaning tank 401. Then, the ultrasonic transducer 402 is turned on. At this time, the ultrasonic transducer 402 will generate ultrasonic waves, producing cavitation and direct flow effects to clean the scale inside the heat exchange pipeline. After cleaning, the operator can take out the heat exchange pipeline and reconnect it to the liquid pump 302 connector 303 and the liquid inlet 307 of the gauge 306. The liquid pump 302 is then turned on to clean the scale that has been detached from the pipeline. The wastewater generated during cleaning will also enter the sewage tank 501.

[0035] like Figure 1 and Figure 6 As shown, the maintenance platform mechanism 1 has a collection mechanism 5 for collecting cleaning fluid fixed inside. The collection mechanism 5 includes a wastewater tank 501 fixed to the bottom wall of the platform body 101. The wastewater tank 501 is welded and fixed to the platform body 101. A drain pipe 502 is also threadedly connected to the platform body 101. An air valve 503 and a drain valve 504 are fixed to the wastewater tank 501. Multiple casters 505 are welded to the bottom of the wastewater tank 501. The drain pipe 502 is a flexible hose, and the top end of the drain pipe 502 is connected to the drain port of the cleaning tank 401. When staff use the device to clean the heat exchange pipeline, they can open the drain switch. At this time, the cleaning liquid in the cleaning tank 401 will flow into the sewage tank 501 through the drain pipe 502. When the cleaning liquid needs to be drained, staff can remove the sewage tank 501 and move it to the designated position using the casters 505, and then drain the sewage through the drain valve 504. This avoids direct discharge of sewage and helps to keep the environment clean and tidy. The air valve 503 can effectively balance the internal and external air pressure of the sewage tank 501 to prevent the water inlet and outlet from being blocked.

[0036] When using this utility model, the operator can first place the heater on the table of the inspection platform 1, and then use the circuit testing mechanism 2 and the pipeline testing mechanism 3 to test the heater's circuit and pipeline respectively. When there is a problem with the circuit, the operator can perform maintenance operations such as wiring and replacing components on the table to repair the heater. When there is scale buildup and blockage in the pipeline, the operator can open the cover 107 and use the cleaning mechanism 4 to perform ultrasonic cleaning of the pipeline.
