Technical Field

[0001] This invention relates to the field of generator set technology, and in particular to a marine diesel engine set. Background Technology

[0002] A diesel generator set is a power supply device that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It is a power generation device that starts quickly, is easy to operate and maintain, requires less investment, and has strong environmental adaptability. Diesel generator sets are needed on ships.

A diesel engine is installed on one side of the upper end of the shock absorber, and a generator is connected to the output shaft of the diesel engine. An energy storage cabinet is arranged on one side of the generator, and a cavity is provided on one side wall of the housing. By setting a humidity probe and a dehumidifier, the humidity probe detects the humidity inside the housing in real time during the power generation process and transmits the detection value to the controller system in the energy storage cabinet. The control system automatically controls the dehumidifier to work according to the detection value to dehumidify the generator set and thus prevent moisture from corroding it.

[0015] Preferably, the length of the heat-conducting column is greater than the length of the dry cotton block; The heat-conducting column is inserted into the cylindrical slot in the middle of the drying cotton block and is connected to the round hole at the end of the carrier. The end of the heat-conducting column is inserted into the contact slot on the conductive distribution strip.

[0016] Preferably, the conductive distribution strip is distributed on the inner side wall of the unit housing, and mounting feet are provided on the conductive distribution strip. The mounting feet are fixedly connected to the inner side wall of the unit housing by screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The marine diesel engine set designed in this invention includes a set housing and a diesel engine main body placed inside it. A door is provided on the front side of the set housing. A heat dissipation window is provided on one side of the set housing, and a mounting slot is provided on the outer side of the heat dissipation window. The mounting slot is used to place a side plate and fix it with screws. Heat dissipation grooves are evenly provided on the side plate to provide a heat dissipation effect for the heat inside the set housing. An auxiliary mechanism is also provided at the heat dissipation window position. This auxiliary mechanism, while providing heat dissipation for the set housing, prevents external humid air from entering the interior of the set housing through the heat dissipation grooves. This solution provides heat dissipation through the side plate and the heat dissipation slots evenly arranged on it. In addition, it uses an auxiliary mechanism to prevent moisture from the external humid environment from entering the generator set housing and affecting the operation of the diesel engine set. Based on this, by placing drying cotton blocks in the receiving cavity of the carrier, if external moisture enters through the heat dissipation slots on the side plate, the drying cotton blocks will dry and absorb the moisture. Furthermore, the auxiliary components also have a certain drying effect on the moisture; that is, the heat-conducting columns and heat-conducting plates absorb heat from inside the unit housing, providing a heating and drying process for the entering moisture, thus providing an auxiliary effect in preventing moisture intrusion. In other words, after installing the drying cotton blocks in the receiving cavity of the carrier, the heat-conducting columns on one side of the heat-conducting plates are then inserted... Insert the cotton into the cylindrical slot in the middle of the drying cotton block until the heat-conducting plate contacts the end of the drying cotton block. The heat-conducting column and heat-conducting plate have a heat absorption and heat conduction effect on the gas. The heated heat-conducting column and heat-conducting plate provide a heating effect on the drying cotton block, which can provide a drying treatment for the damp part of the drying cotton block to ensure the drying effect of the drying cotton block on moisture absorption. For external moisture, it will also come into contact with the heated heat-conducting plate. At this time, the heat-conducting plate can also provide a drying treatment for the invading moisture, so as to reduce the working pressure of the drying cotton block and have a good auxiliary effect. In addition, the heat-conducting columns and conductive distribution strips in the auxiliary components work together to recover and utilize the internal heat of the unit housing, thus providing a drying aid for the moisture inside the housing.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-11 A marine diesel engine set includes an engine housing 2 and a diesel engine body 1 placed inside it. A door 3 is provided on the front side of the engine housing 2. A heat dissipation window 21 is provided on one side of the engine housing 2, and a mounting slot 22 is provided on the outer side of the heat dissipation window 21. The mounting slot 22 is used to place the side plate 4 and is fixed with screws. The side plate 4 is evenly provided with heat dissipation grooves 41, which are used to dissipate heat inside the unit housing 2. An auxiliary mechanism is also provided at the heat dissipation window 21. The auxiliary mechanism not only provides heat dissipation for the unit housing 2, but also prevents external humid air from entering the unit housing 2 through the heat dissipation grooves 41.

[0022] According to the appendix Figure 1-7 As shown, this solution provides heat dissipation through the side plate 4 and the heat dissipation slots 41 evenly arranged on it. In addition, the auxiliary mechanism is set to prevent moisture from the external humid environment from entering the unit housing 2 and affecting the operation of the diesel engine unit body 1. By setting a drying cotton block 602 in the receiving cavity 504 of the carrier 503, if external moisture enters through the heat dissipation groove 41 on the side plate 4, the drying cotton block 602 will dry and absorb the moisture. Furthermore, the auxiliary components also have a certain drying effect on the moisture. That is, the heat-conducting column 701 and heat-conducting plate 702 absorb the heat inside the unit box 2, provide a heating and drying treatment for the moisture that enters, and provide an auxiliary effect in preventing the intrusion of moisture. In addition, the heat-conducting column 701 and the conductive distribution strip 801 in the auxiliary components work together to recover and utilize the internal heat of the unit housing 2, thereby providing a drying assistance for the moisture inside the housing.

[0023] Combined with appendix Figure 3-9 As shown, the auxiliary mechanism includes a support plate 501; limit clamps 502 are fixedly provided on the four sides of the support plate 501, and the limit clamps 502 are adapted to and engaged with the mounting slots 22 to provide installation for the support plate 501; mounting carriers 503 are fixedly provided at equal intervals on one side of the support plate 501; the mounting carriers 503 are positioned corresponding to the heat dissipation slots 41 on the side plate 4 and have the same number of sets; a receiving cavity 504 is also provided in the mounting carrier 503, and the opening of the receiving cavity 504 extends to the other side of the support plate 501.

[0024] For the installation and use of the support plate 501, the limiting clip 502 on the side of the support plate 501 is clipped into the mounting slot 22 on the outside of the heat dissipation window 21. The limiting clip 502 is also provided with mounting holes. Then, the side plate 4 is clipped into the mounting slot 22. At this time, the mounting holes on the side plate 4 and the limiting clip 502 are aligned and aligned with the screw grooves provided in the mounting slot 22. Then, the side plate 4 and the limiting clip 502 are fixed with screws, that is, the support plate 501 is fixed.

[0025] Combined with the appendix Figure 9-11 As shown, the auxiliary mechanism also includes a ventilation groove 601 disposed on the side of the carrier 503, which is connected to the receiving cavity 504 inside the carrier 503; a circular hole is provided at the center of the end of the carrier 503, which is also connected to the receiving cavity 504; a drying cotton block 602 is placed in the receiving cavity 504; the end shape of the drying cotton block 602 and the shape of the opening of the receiving cavity 504 are both square, and one drying cotton block 602 is disposed in one receiving cavity 504; the drying cotton block 602 is used to provide a drying effect for the moisture entering from the outside.

[0026] Before installing the support plate 501, a drying cotton block 602 is placed in the receiving cavity 504 of the carrier 503. The drying cotton block 602 is used to provide a drying and absorption treatment for the external moisture, so as to prevent external moisture from entering the unit housing 2 and affecting the operation of the diesel engine unit body 1 while ensuring normal heat dissipation.

[0027] When the heat dissipation channel 41 in the side plate 4 provides heat dissipation for the interior of the unit housing 2, external moisture may also enter the interior cavity of the unit housing 2 through the heat dissipation channel 41. In order to prevent external moisture from entering the interior cavity of the unit housing 2, this solution also provides a supporting plate 501 on the inner side of the side plate 4, and a drying cotton block 602 is installed in the receiving cavity 504 of the carrier 503 on the supporting plate 501 to provide a blocking and drying absorption effect for external moisture.

[0028] From the appendix Figure 10-11 As shown, in order to ensure that the heat in the inner cavity of the unit housing 2 can be dissipated smoothly, this solution provides a ventilation groove 601 on the side of the carrier 503, and side grooves 603 are provided at equal intervals on the side wall of the drying cotton block 602. An end groove 604 is also provided at equal intervals at one end of the drying cotton block 602. The end groove 604 and the side groove 603 are connected and used together to provide a flow for the gas.

[0029] That is, after the drying cotton block 602 is placed in the receiving cavity 504 of the carrier 503, when one end of the drying cotton block 602 contacts the bottom end of the receiving cavity 504, the side groove 603 of the drying cotton block 602 is aligned with the ventilation groove 601 on the side of the carrier 503. The heat inside the unit box 2 enters from the ventilation groove 601 on the side of the carrier 503, then enters from the side groove 603 of the drying cotton block 602, and then exits from the end groove 604 of the drying cotton block 602, and finally exits from the heat dissipation groove 41 on the side plate 4.

[0030] Combined with the appendix Figure 3 and appendix Figure 8-11 As shown, this solution provides a barrier and absorption function for external moisture intrusion by setting drying cotton blocks 602 in the receiving cavity 504 on the carrier 503, that is, by uniformly setting multiple sets of drying cotton blocks 602 on the carrier plate 501. This provides a protective measure for the internal dry environment of the unit box 2. When moisture passes through the drying cotton blocks 602, the moisture is absorbed in the drying cotton blocks 602.

[0031] Regarding the heat dissipation operation inside the unit housing 2, when the heat inside the unit housing 2 is discharged outward through the drying cotton block 602, the heated gas can also provide a drying and heating effect on the drying cotton block 602, that is, heat and dry the moisture absorbed on the drying cotton block 602, so as to prevent the drying cotton block 602 from becoming too damp inside after long-term use, which would affect the drying and absorption effect of the drying cotton block 602 on moisture.

[0032] In this solution, the drying cotton block 602 is placed in the receiving cavity 504 of the carrier 503, which is detachable to facilitate future replacement and maintenance.

[0033] From the appendix Figure 7-11 As shown, in order to further improve the drying effect of externally intrusive moisture, this solution also includes auxiliary components.

[0034] In this design, a cylindrical slot is provided in the middle of the drying cotton block 602. The cylindrical slot is used to connect an auxiliary component. The auxiliary component includes a heat-conducting column 701 that is inserted into the cylindrical slot in the middle of the drying cotton block 602. A heat-conducting plate 702 is fixedly provided at one end of the heat-conducting column 701, and an auxiliary mesh body 703 is provided in the heat-conducting plate 702. The auxiliary mesh body 703 is positioned corresponding to the end groove 604 at the end of the drying cotton block 602.

[0035] That is, after the drying cotton block 602 is installed in the receiving cavity 504 in the carrier 503, the heat-conducting column 701 on one side of the heat-conducting plate 702 is inserted into the cylindrical slot in the middle of the drying cotton block 602 until the heat-conducting plate 702 contacts the end of the drying cotton block 602. At the same time, the auxiliary mesh body 703 provided on the heat-conducting plate 702 will be aligned with the end groove 604 at the end of the drying cotton block 602. The length of the heat-conducting column 701 is greater than the length of the drying cotton block 602. That is, after the heat-conducting column 701 is inserted into the cylindrical slot in the middle of the drying cotton block 602, it will pass through the mesh at the end of the carrier 503.

[0036] According to the appendix Figure 7 and attached Figure 9 As shown, a support bar 704 is provided in the heat dissipation groove 41 on the side plate 4; and a limiting top bar 705 is fixedly provided on one side of the support bar 704. The limiting top bar 705 is used to provide support for the heat-conducting plate 702. That is, after each drying cotton block 602 is placed in the receiving cavity 504 in the carrier 503, the heat-conducting column 701 is inserted into the cylindrical slot of the drying cotton block 602 until the heat-conducting plate 702 at one end of the heat-conducting column 701 is in close contact with the end position of the drying cotton block 602.

[0037] Next, place the support plate 501 in the heat dissipation window 21, and ensure that the limiting clip 502 on the side of the support plate 501 is engaged in the mounting slot 22. Then place the side plate 4 in the mounting slot 22 and fix the side plate 4 and the support plate 501 together with screws.

[0038] During this process, the side plate 4 will come into contact with the supporting plate 501, and one end of the limiting top strip 705 provided in the heat dissipation groove 41 on the side plate 4 will come into contact with the heat-conducting plate 702. The function of the limiting top strip 705 here is to provide a limiting function for the heat-conducting plate 702, that is, to ensure the stability of the heat-conducting column 701 inserted into the cylindrical slot on the drying cotton block 602. In other words, after the heat-conducting column 701 and the heat-conducting plate 702 are installed, the limiting top strip 705 is used to press against the heat-conducting plate 702, thereby ensuring the installation stability of both the heat-conducting plate 702 and the heat-conducting column 701.

[0039] Combined with the appendix Figure 7 Appendix Figure 9 and attached Figure 10 As shown, the heat-conducting column 701 and heat-conducting plate 702 provided in this scheme can provide an absorption and utilization effect for the heat inside the unit housing 2.

[0040] When dissipating heat from the unit housing 2, the heat in the gas passes through the heat-conducting column 701. The heat-conducting column 701 and the heat-conducting plate 702 absorb and conduct heat from the gas. During this process, on the one hand, the heated heat-conducting column 701 and the heat-conducting plate 702 provide a heating effect on the drying cotton block 602, which can provide a drying treatment for the damp part of the drying cotton block 602 to ensure the drying effect of the drying cotton block 602 on moisture absorption. On the other hand, externally invading moisture will also come into contact with the heated heat-conducting plate 702. At this time, the heat-conducting plate 702 can also provide a drying treatment for the invading moisture to reduce the working pressure of the drying cotton block 602.

[0041] Combined with the appendix Figure 2-5 As shown, the end of the heat-conducting column 701 is inserted into the contact slot 802 on the conductive distribution strip 801; the conductive distribution strip 801 is distributed on the inner side wall of the unit housing 2, and mounting feet 803 are provided on the conductive distribution strip 801, which are fixedly connected to the inner side wall of the unit housing 2 by screws.

[0042] In this design, the conductive distribution strips 801 are evenly distributed on the inner side wall of the unit housing 2, and are fixed to the side wall of the unit housing 2 by the cooperation of the mounting feet 803 and screws. The conductive distribution strips 801 are also provided with contact slots 802, which are adapted to engage with the end of the heat-conducting column 701; that is, after the heat-conducting column 701 passes through the end mesh of the carrier 503, it engages with the contact slots 802 on the conductive distribution strips 801. When the unit housing 2 dissipates heat, the conductive distribution strip 801 can distribute the heat in the gas evenly and provide an auxiliary drying effect for the humid gas in the unit housing 2; that is, it can recover and utilize the internal heat of the unit housing 2 to provide an auxiliary drying effect for the moisture inside the housing.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
