Description

Technical Field

[0001] The utility model relates to the technical field of generator equipment, in particular to a leakage prevention structure for a generator set. Background Art

[0002] Generator sets are commonly used in fields such as infrastructure construction, communication stations, disaster relief, etc., and have the advantages of simple use, high utilization efficiency, and convenient transportation. Due to the need for frequent transportation, hoisting, and installation operations, and the relatively harsh working environment, leakage often occurs in generator sets, and fuels, coolants, and internal and external water may all leak. At present, how to effectively detect the leakage of liquids (including fuels, coolants, and internal and external water ingress) in containerized diesel generator sets has always been a difficult problem in the industry. Usually, a leakage detection rope is arranged around the drip tray of the daily-use fuel tank for single leakage detection, which cannot perform targeted comprehensive treatment and cannot detect corresponding leaks for different media. Content of the Utility Model

[0003] Aiming at the defects existing in the prior art, the utility model provides a leakage detection structure for a containerized generator set with a simple structure, reasonable design, more comprehensive and effective detection range, and convenient use.

[0005] Further, the collecting groove is arranged between the generator set and the fuel tank, the fuel tank and the generator set are separated on both sides by the collecting groove, and both ends of the collecting groove are respectively close to the closed enclosures on the front and rear sides.

[0006] Preferably, the photoelectric detection sensor adopts an explosion-proof photoelectric leakage sensor, which is connected to the controller through a communication line. This sensor can identify different types of liquids through the difference in light reflection rate and transmit the signal to the controller.

[0007] Preferably, the communication line adopts an RS485 serial bus.

[0008] Preferably, the height of the closed enclosure is 40 - 100 mm, such as 100 mm.

[0009] Furthermore, a depression is provided at the middle position of the collection tank, and the depth of the depression is greater than that of other positions of the collection tank, so as to facilitate the collection of leaked liquid. The photoelectric detection sensor is aligned with the depression in an upright posture.

[0010] Preferably, the maximum depth of the collection tank does not exceed 100 mm.

[0011] The utility model achieves the function of continuously detecting leakage by arranging a sealing layer at the bottom of the container for installing a generator set and a fuel tank, arranging a closed enclosure around the sealing layer to block the outflow of leaked liquid, arranging a downwardly concave collection tank on the sealing layer to collect the leaked medium, and installing a photoelectric detection sensor in the collection tank to detect the leaked medium. It has the advantages of wide detection range, flexible setting, high reliability, etc. At the same time, the detection types are complete, and it can identify media such as fuel, coolant, and internal and external water and output alarm signals respectively, and can also set single leakage source detection alarm. It is more accurate and has more complete functions than the traditional leakage detection rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is a schematic structural diagram of the utility model.

[0013] In the figure, 1 is a container, 2 is a sealing layer, 3 is a closed enclosure, 4 is a generator set, 5 is a fuel tank, 6 is a collection tank, 7 is a photoelectric detection sensor, and 8 is a communication line. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In this embodiment, referring to Figure 1 , the leakage detection structure of the container-type generator set includes a container 1, a sealing layer 2 is arranged at the bottom of the container 1, and the sealing layer 2 can prevent seepage; a closed enclosure 3 is arranged along the periphery of the sealing layer 2, and the closed enclosure 3 is hermetically connected to the sealing layer 2 to prevent the leakage of leaked liquid; a space for installing a generator set 4 and a fuel tank 5 is enclosed on the sealing layer 2 by the closed enclosure 3, and the generator set 4 and the fuel tank 5 are installed on the sealing layer 2; a downwardly concave collection tank 6 is arranged on the sealing layer 2, and the inside of the collection tank 6 is a sealed structure to prevent liquid seepage; a photoelectric detection sensor 7 is arranged in the collection tank 6, and the photoelectric detection sensor 7 is connected to a controller (not shown).

[0015] The collection tank 6 is arranged between the generator set 4 and the fuel tank 5, and the fuel tank 5 and the generator set 4 are separated by the collection tank 6 on both sides, one on the left and one on the right, and both ends of the collection tank 6 are respectively close to the closed enclosures 3 on the front and rear sides.

[0016] The photoelectric detection sensor 7 adopts an explosion-proof photoelectric leakage sensor, which is connected to the controller through a communication line 8. The sensor can identify different types of liquids through the difference in light irradiation reflectivity and transmit the signal to the controller.

[0017] The communication line 8 adopts an RS485 serial bus.

[0018] The height of the closed enclosure 3 is 40 - 100 mm, for example, 100 mm.

[0019] The middle position of the collection tank 6 has a depression, and the depth of the depression is greater than the depth of other positions of the collection tank 6, so as to facilitate the collection of the leaked liquid.

[0020] The maximum depth of the collection tank 6 does not exceed 100 mm.

[0021] When a liquid (such as fuel, coolant, and internal and external water ingress, etc.) leaks onto the sealing layer 2, due to the barrier of the closed enclosure 3, it will not flow outside, but will flow into the collection tank 6, and then be detected by the optoelectronic detection sensor 7. The optoelectronic detection sensor 7 transmits the detection signal to the controller to identify the leakage information.

[0022] The above has made a detailed description of the present utility model. The above description is only a preferred embodiment of the present utility model, and it cannot limit the scope of implementation of the present utility model. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
