Description

Technical Field

[0001] This utility model relates to the field of fuel tank heating devices, and in particular to a fuel tank heating device with an early warning mechanism. Background Technology

[0002] In high-altitude and frigid regions during winter construction, the normal operation of machinery and equipment faces significant challenges. In low temperatures, fuel in the tank becomes viscous or even solidifies, making engine starting difficult and severely impacting construction progress and efficiency. To ensure smooth construction, the fuel in the tank needs to be heated to maintain its good fluidity, meeting the requirements for engine starting and continuous operation. Therefore, fuel tank heating devices with early warning mechanisms have become key auxiliary equipment for machinery and equipment used in winter construction in high-altitude and frigid regions, playing a crucial role in ensuring the normal operation of construction activities.

[0003] Currently, fuel tank heating devices used in high-altitude and cold regions have many problems. Traditional heating devices are mostly simple in structure, employing only a single heating method, such as directly installing heating elements on the outside of the fuel tank. This method not only has low heating efficiency and cannot quickly bring the fuel to the appropriate temperature, but also easily causes uneven heating, with some fuel failing to be effectively heated, making engine starting difficult. At the same time, existing heating devices lack effective explosion-proof and protective measures. In high-altitude and cold regions, the operating environment is complex; if a malfunction occurs inside the heating device, such as a short circuit generating sparks, it can easily lead to an explosion, posing a serious threat to surrounding personnel and equipment. Moreover, during daily storage and handling, the heating device is easily affected by external impacts and pressure, leading to component damage, reduced heating efficiency, or even malfunction. Furthermore, existing heating devices usually lack a warning mechanism and cannot monitor the temperature inside the fuel tank in real time. Operators find it difficult to determine whether the fuel has been heated to the appropriate temperature; overheating not only wastes energy but may also damage the fuel tank and engine; underheating fails to meet the starting requirements. In addition, different construction equipment has different oil tank diameters, but the existing devices have poor compatibility and are difficult to install stably on different oil tanks. During the heating process, they are prone to shaking, falling off, etc., which affects the heating effect.

[0004] Therefore, in response to the problems of existing fuel tank heating devices in high-altitude and cold regions, where the operating environment is complex and the existing heating devices usually lack an early warning mechanism and cannot monitor the temperature inside the fuel tank in real time, and therefore cannot meet the start-up requirements if the heating is insufficient, a fuel tank heating device with an early warning mechanism is needed to solve the above problems. Utility Model Content

[0005] To address the problems of existing technologies in high-altitude and cold regions where the equipment operates in complex environments and where existing heating devices typically lack early warning mechanisms and cannot monitor the temperature inside the fuel tank in real time, thus failing to meet startup requirements if heating is insufficient, this application provides a fuel tank heating device with an early warning mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fuel tank heating device with a warning mechanism includes an explosion-proof housing for a heating tube. Two arc-shaped adjusting clamps are disposed at the top of the explosion-proof housing. Two second preset connecting plates are fixedly connected to the outer wall of the explosion-proof housing. A first preset connecting plate is fixedly connected to one end of each of the two arc-shaped adjusting clamps. The first preset connecting plates are connected to the second preset connecting plates via connecting components. An adjusting component is disposed on the side of each of the two arc-shaped adjusting clamps that is close to each other. A preset mounting plate is slidably connected to the bottom side of each of the two arc-shaped adjusting clamps. A preset slider is fixedly connected to the bottom side of each of the two arc-shaped adjusting clamps. Two reserved sliding grooves are formed on the top side of the preset mounting plate. The outer wall of the preset slider is slidably connected to the inner wall of the reserved sliding groove.

[0008] As a further improvement of this utility model, the connecting assembly includes a preset adjusting rod that is slidably connected to the interior of the two second preset connecting plates. The bottom ends of the two preset adjusting rods are threaded with adjusting screw caps. The top sides of the two preset adjusting rods are provided with preset limiting rings. The outer walls of the two preset adjusting rods are fixedly connected with preset limiting strips. The top ends of the two preset adjusting rods are fixedly connected with preset limiting blocks.

[0009] As a further improvement of this utility model, the two preset limiting rings are provided with reserved semi-through grooves at both the front and rear ends, and the two preset limiting rings are provided with reserved through grooves at both the left and right ends. The outer wall of the preset limiting strip is slidably connected to the inner wall of the second preset connecting plate.

[0010] As a further improvement of this utility model, the adjustment assembly includes an adjustment slide cylinder that is fixedly connected to the front end of the left-end arc-shaped adjustment clamp and the rear end of the right-end arc-shaped adjustment clamp, and a limit spring is provided on the bottom side of the arc-shaped adjustment clamp.

[0011] As a further improvement of this utility model, one end of the limiting tension spring is connected to the adjusting slide cylinder, and the other end is connected to the inside of the two arc-shaped adjusting clamps.

[0030] Example 1:

[0031] refer to Figure 2 and Figure 4 A fuel tank heating device with an early warning mechanism includes an explosion-proof housing 1 for a heating tube. Two arc-shaped adjusting plates 2 are located at the top of the housing 1. Two second preset connecting plates 6 are fixedly connected to the outer wall of the housing 1. A first preset connecting plate 5 is fixedly connected to one end of each of the two arc-shaped adjusting plates 2. The first preset connecting plate 5 is connected to the second preset connecting plate 6 via a preset adjusting rod 8. A limit spring 16 is provided on the side of the two arc-shaped adjusting plates 2 closest to each other. A preset mounting plate 17 is slidably connected to the bottom of each of the two arc-shaped adjusting plates 2. A preset slider 13 is fixedly connected to the bottom of each of the two arc-shaped adjusting plates 2. Two reserved sliding grooves 14 are formed on the top side of the preset mounting plate 17, and the outer wall of the preset slider 13 is slidably connected to the inner wall of the reserved sliding grooves 14. Two heating tube bodies 7 are located on the bottom side of the preset mounting plate 17, and a power control line 4 is located on the top side of the preset mounting plate 17. An overheat alarm light 3 is located on the top side of each of the two arc-shaped adjusting plates 2.

[0032] Specifically, the explosion-proof housing 1 of the heating tube is fitted over the outer wall of the heating tube body 7 and then placed inside the fuel tank to heat the fuel. The explosion-proof housing 1 is made of high-strength, explosion-proof material, a design that serves a dual purpose. In the event of a malfunction within the heating device that generates sparks or high temperatures, the explosion-proof housing effectively prevents the outward spread of explosive energy, greatly protecting the safety of the surrounding environment. During storage, it also protects the heating tube body 7, preventing external factors from affecting it and avoiding a reduction in heating efficiency. Simultaneously, the overheat alarm light 3 on the arc-shaped adjusting plate 2 monitors the temperature in real time; if the temperature becomes too high, an alarm will sound, promptly reminding the operator to take appropriate measures.

[0033] refer to Figure 4 An adjusting cylinder 15 is fixedly connected to the front end of the left-end arc-shaped adjusting clamp 2 and the rear end of the right-end arc-shaped adjusting clamp 2. A limiting spring 16 is provided on the bottom side of the arc-shaped adjusting clamp 2. One end of the limiting spring 16 is connected to the adjusting cylinder 15, and the other end is connected to the inside of the two arc-shaped adjusting clamps 2.

[0034] Specifically, considering the differences in fuel tank opening diameters across different vehicle models, the device also features an adjustable clamping structure. By pulling the arc-shaped adjusting plates 2 in opposite directions, the operator can open the two plates, facilitating the clamping of fuel tank openings of varying diameters. When the two arc-shaped adjusting plates 2 are released, the limiting spring 16, through its restoring and elastic action, maintains a stable clamping effect on the fuel tank opening, ensuring a tight connection between the heating device and the fuel tank and guaranteeing smooth heating.

[0035] Example 2:

[0036] As one of the optimized structural designs for Example 1, such as Figure 1 and Figure 3 As shown, two preset adjusting rods 8 are slidably connected inside the two second preset connecting plates 6. Adjusting screw caps 11 are threaded to the bottom ends of both preset adjusting rods 8. Preset limiting rings 12 are provided on the top sides of both preset adjusting rods 8. Preset limiting strips 10 are fixedly connected to the outer walls of both preset adjusting rods 8. Preset limiting blocks 9 are fixedly connected to the top ends of both preset adjusting rods 8. Reserved semi-through grooves are opened at both the front and rear ends of the two preset limiting rings 12, and reserved through grooves are opened at both the left and right ends of the two preset limiting rings 12. The outer wall of the preset limiting strip 10 is slidably connected to the inner wall of the second preset connecting plate 6.

[0037] Specifically, the operator rotates the adjusting screw cap 11. Utilizing the threaded connection principle, and under the limiting action of the preset limiting strip 10, the preset adjusting rod 8 can only move vertically within the second preset connecting plate 6. When the preset adjusting rod 8 moves upward, the preset limiting block 9 at its top disengages from the pre-reserved semi-through slot on the preset limiting ring 12. At this time, the operator aligns the position of the pre-reserved through slot on the preset limiting ring 12 with the position of the preset limiting block 9, and can easily remove the preset limiting ring 12, thereby separating the arc-shaped adjusting clamp 2 from the explosion-proof housing 1 of the heating tube, and then using the heating tube body 7 for separate heating.

[0038] Working principle: This utility model has two heating methods for heating fuel in the fuel tank. First, the explosion-proof housing 1 of the heating tube is fitted onto the outer wall of the heating tube body 7. The entire explosion-proof housing 1 is then placed inside the fuel tank to heat the fuel. The explosion-proof housing 1 is made of high-strength, explosion-proof material. When a malfunction occurs inside the heating device and sparks or high temperatures are generated, the explosion-proof housing can prevent the explosion energy from spreading outward and protect the surrounding environment. At the same time, when storing the heating tube, the explosion-proof housing 1 can also protect the heating tube body 7, preventing it from being affected by external factors and reducing heating efficiency. Meanwhile, the overheat alarm light 3 on the arc-shaped adjusting clamp 2 will sound an alarm to remind the operator when the temperature is too high.

[0039] If only the heating tube body 7 is needed to heat the fuel, the operator can rotate the adjusting screw cap 11. Under the action of the threaded connection and the limiting action of the preset limiting strip 10, the preset adjusting rod 8 can only move in a straight line in the vertical direction inside the second preset connecting plate 6. When the preset adjusting rod 8 moves upward, the preset limiting block 9 at its top will disengage from the pre-reserved semi-through groove on the preset limiting ring 12. At this time, the operator can align the position of the pre-reserved through groove on the preset limiting ring 12 with the position of the preset limiting block 9 to remove the preset limiting ring 12, thereby separating the arc-shaped adjusting clamp 2 from the explosion-proof shell 1 of the heating tube, and heating can be performed separately through the heating tube body 7.

[0040] Since the fuel tank opening diameter varies for different vehicle models, the operator can pull the arc-shaped adjusting clamp 2 in opposite directions to open the two arc-shaped adjusting clamps 2 so that the two arc-shaped adjusting clamps 2 can clamp the fuel tank opening. When the two arc-shaped adjusting clamps 2 are released, the fuel tank opening can be continuously clamped under the reset and elastic action of the limiting tension spring 16.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
