Description

Technical Field

[0001] The present invention relates to the technical field of generators, in particular to a fixing structure for assembling a diesel generator. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine, or other power machinery, converting the energy generated by water flow, air flow, and fuel combustion into mechanical energy, which is transmitted to the generator, and then converted into electrical energy by the generator. Currently, most generators on the market are assembled without a supporting fixed structure, which makes the generator prone to accidental movement and overturning during the assembly process. At the same time, the generator is generally inconvenient to move again, making the installation and use of the generator after assembly inconvenient. It is necessary to propose a solution to solve the above technical problems.

[0003] As disclosed in the patent document with publication number CN217216242U, the device can detachably connect the connecting rod and the support column by rotating the nut along the external thread, effectively realizing that the structure can limit and fix the generator to the upper surface of the base under the action of the support column, the clamping plate and the connecting rod, and the distance between the two clamping plates can be adjusted in various ways under the action of multiple limiting grooves, thereby being suitable for generators of various sizes. This solves the problem that most generators on the market currently have no supporting and fixing structure during assembly, which leads to the problem that the generators are prone to accidental movement and overturning during assembly, and effectively ensures the safety and stability of the generator during assembly.

[0004] However, the above-mentioned device can only be used for generators with smaller size and weight. When facing a diesel generator, due to its large weight and size, an external lifting device is required for auxiliary installation and fixation. When the cooling fan for the diesel generator is hoisted by the external lifting device, the cooling fan will shake, which may easily cause harm to the surrounding operators; at the same time, it is difficult to put it into the fan mounting seat quickly and effectively. The existing method is to slowly adjust the position of the cooling fan manually, which takes a lot of time and is inefficient. Summary of the Invention

[0005] The technical problems solved by this solution are:

[0006] (1) How to quickly locate the cooling fan for a diesel generator to prevent it from shaking and causing harm to surrounding operators.

[0007] (2) How to solve the problem of conveniently and accurately placing the cooling fan for the diesel generator into the fan mounting base.

[0008] The objectives of the present invention can be achieved through the following technical solutions: A fixed structure for assembling a diesel generator, comprising a base and a fan mounting seat fixed on the top thereof, wherein a limiting mechanism for quickly positioning a cooling fan for the diesel generator is movably provided on one side of the fan mounting seat, and a guide mechanism for guiding the cooling fan for the diesel generator to be placed on the fan inlet mounting seat is provided on the other side of the fan mounting seat;

[0009] The limiting mechanism includes a movable seat slidably connected to the base through a guide rail, a mounting plate is fixedly mounted on the movable seat, a sliding groove is provided on the mounting plate facing the side of the fan mounting seat, a slider is slidingly arranged inside the sliding groove, an inclined bracket is fixedly mounted on one end of the slider, a magnet plate is fixedly mounted on the top of the bracket, and a shock-absorbing unit for preventing the cooling fan for the diesel generator from shaking is movably arranged above the magnet plate.

[0010] A further technical improvement of the present invention is that two guide rods are movably inserted into the slider, the two guide rods are symmetrically arranged, and thrust springs are movably sleeved on the two guide rods.

[0011] A further technical improvement of the present invention is that a cylinder is longitudinally arranged on the movable seat, and the protruding end of the cylinder is fixedly connected to the slider.

[0012] A further technical improvement of the present invention is that: the shock-absorbing unit includes two rotating seats fixedly mounted on the mounting plate, a rotating rod is rotatably arranged on the rotating seat, a magnet ball is arranged between the two rotating rods, the two rotating rods are elastically connected to the magnet balls through tension springs respectively, and the magnet plate is located below the magnet ball and the mounting plate; by lowering the cooling fan to a set height, at this time, the protruding end of the cylinder is extended to half its length, and the magnet ball is magnetically connected to the bottom of the cooling fan, and at this time the magnet ball will swing with the cooling fan, and due to the tension of the two tension springs, the cooling fan gradually stops swinging, which not only speeds up the limiting of the cooling fan, but also avoids the process of manual adjustment of the cooling fan, preventing it from injuring the surrounding operators.

[0013] A further technical improvement of the present invention is that a transmission rod is hinged to the middle of the rotating rod, and a support block is hinged to one end of the transmission rod. The two support blocks are both located inside the slide groove, and the two support blocks are respectively fixedly connected to the top ends of the corresponding guide rods.

[0014] A further technical improvement of the present invention is that: the guide mechanism includes a guide groove fixedly mounted on the base, the size of the guide groove corresponds to the size of the cooling fan for the diesel generator, and a number of guide wheels are symmetrically arranged on the inner wall of the guide groove, and a rubber sleeve is fixedly sleeved on the circumferential surface of the guide wheel; the protruding end of the cylinder is extended to the longest state, at this time, the slider drives the magnet plate to slide upward, the magnet plate is magnetically connected to the side of the cooling fan, and then contracts to the shortest state through the protruding end of the cylinder. During this process, the external lifting device will also slowly lower the cooling fan, so that the magnet plate steadily drives the cooling fan to move downward. When the protruding end of the cylinder is contracted to the shortest state, one side of the cooling fan is located in the guide groove, thereby conveniently and accurately placing the cooling fan into the fan mounting seat.

[0015] A further technical improvement of the present invention is that a driving tool for driving the installation plate to move is fixedly installed on the back of the base, and the driving tool is a prior art; by driving the installation plate to move, not only the position of the installation plate can be adjusted, but also the magnet plate can be separated from the cooling fan, making it convenient to move the cooling fan a second time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present invention is in use, the heat dissipation fan is lowered to a set height. At this time, the protruding end of the cylinder is extended to half the length, and the magnetic ball is magnetically connected to the bottom of the heat dissipation fan. At this time, the magnetic ball will swing with the heat dissipation fan. Due to the tension of the two tension springs, the heat dissipation fan gradually stops swinging, which not only speeds up the position limiting of the heat dissipation fan, but also avoids the process of manual adjustment of the heat dissipation fan, preventing it from injuring surrounding operators.

[0018] When the present invention is in use, the protruding end of the cylinder is extended to its longest state. At this time, the slider drives the magnet plate to slide upward, and the magnet plate is magnetically connected to the side of the heat dissipation fan. Then, the protruding end of the cylinder is retracted to the shortest state. During this process, the external lifting device will also slowly lower the heat dissipation fan, so that the magnet plate can smoothly drive the heat dissipation fan to move downward. When the protruding end of the cylinder is retracted to the shortest state, one side of the heat dissipation fan is located in the guide groove, thereby conveniently and accurately placing the heat dissipation fan into the fan mounting base.

The mounting plate 101 is provided with a slide groove 108 on the side facing the fan mounting seat 4, and a slider 109 is slidingly provided inside the slide groove 108. An inclined bracket 110 is fixedly installed at one end of the slider 109, and a magnet plate 104 is fixedly installed on the top of the bracket 110. A shock-absorbing unit 105 for preventing the cooling fan for the diesel generator from shaking is movably provided above the magnet plate 104.

[0029] See also Figure 3 As shown, two guide rods 106 are movably inserted into the slider 109 . The two guide rods 106 are symmetrically arranged, and thrust springs 107 are movably sleeved on the two guide rods 106 .

[0030] See also Figure 2 and Figure 3 As shown, a cylinder 103 is longitudinally arranged on the above-mentioned moving seat 102, and the protruding end of the cylinder 103 is fixedly connected to the slider 109.

[0031] See also Figure 2-Figure 4 As shown, the above-mentioned shock-absorbing unit 105 includes two rotating seats 1051 fixedly mounted on the mounting plate 101, and a rotating rod 1054 is rotatably arranged on the rotating seat 1051, and a magnetic ball 1056 is arranged between the two rotating rods 1054, and the two rotating rods 1054 are elastically connected to the magnetic ball 1056 through tension springs 1055 respectively, and the magnet plate 104 is located below between the magnetic ball 1056 and the mounting plate 101; by lowering the cooling fan to a set height, at this time, the protruding end of the cylinder 103 is extended to half its length, and the magnetic ball 1056 is magnetically connected to the bottom of the cooling fan, and at this time the magnetic ball 1056 will swing with the cooling fan. Due to the tension of the two tension springs 1055, the cooling fan gradually stops swinging, which not only speeds up the limiting of the cooling fan, but also avoids the process of manual adjustment of the cooling fan, preventing it from injuring the surrounding operators.

[0032] See also Figure 3 and Figure 4 As shown, the middle part of the above-mentioned rotating rod 1054 is hinged with a transmission rod 1053, and one end of the transmission rod 1053 is hinged with a support block 1052. The two support blocks 1052 are both located inside the slide groove 108, and the two support blocks 1052 are respectively fixedly connected to the top of the corresponding guide rod 106.

[0033] See also Figure 5As shown, the above-mentioned guide mechanism 5 includes a guide groove 502 fixedly mounted on the base 3. The size of the guide groove 502 corresponds to the size of the cooling fan for the diesel generator, and a plurality of guide wheels 503 are symmetrically arranged on the inner wall of the guide groove 502. A rubber sleeve 501 is fixedly sleeved on the circumferential surface of the guide wheel 503. The protruding end of the cylinder 103 is extended to the longest state. At this time, the slider 109 drives the magnet plate 104 to slide upward. The magnet plate 104 is magnetically connected to the side of the cooling fan, and then the protruding end of the cylinder 103 is retracted to the shortest state. During this process, the external lifting device will also slowly lower the cooling fan, so that the magnet plate 104 steadily drives the cooling fan to move downward. When the protruding end of the cylinder 103 is retracted to the shortest state, one side of the cooling fan is located in the guide groove 502, thereby conveniently and accurately placing the cooling fan into the fan mounting base 4.

[0034] See also Figure 1 As shown, a driving fixture 2 for driving the installation plate 101 to move is fixedly installed on the back of the above-mentioned base 3, and the driving fixture 2 is a prior art; by driving the installation plate 101 to move by the driving fixture 2, not only the position of the installation plate 101 can be adjusted, but also the magnet plate 104 will be separated from the cooling fan, making it convenient to move the cooling fan a second time.

[0035] Working principle: When the present invention is in use, first, when the external lifting device is used to lift the cooling fan for the diesel generator, the cooling fan is lifted to the top of the fan mounting seat 4 by the external lifting device, and then the cooling fan is slowly lowered to the set height. At this time, the protruding end of the cylinder 103 is extended to half its length, and the magnetic ball 1056 is magnetically connected to the bottom of the cooling fan. At this time, the magnetic ball 1056 will swing with the cooling fan. Due to the tension of the two tension springs 1055, the cooling fan gradually stops swinging, which not only speeds up the limiting of the cooling fan, but also avoids the process of manual adjustment of the cooling fan, preventing it from injuring the surrounding operators; when the cooling fan does not shake, the protruding end of the cylinder 103 is extended to the longest state. At this time, the slider 109 drives the magnet plate 104 to slide upward, the thrust spring 107 contracts, and the magnet plate 104 passes through the area between the two rotating rods 1054 and is magnetically connected to the side of the cooling fan, and then through The extended end of the cylinder 103 is retracted to its shortest state. During this process, the external lifting device will slowly lower the cooling fan, so that the magnet plate 104 can smoothly drive the cooling fan to move downward. At the same time, the bottom of the cooling fan provides pressure on the two rotating rods 1054, causing them to flip, thereby causing the magnetic ball 1056 to separate from the bottom of the cooling fan. When the extended end of the cylinder 103 is retracted to its shortest state, the two transmission rods 1053 pull the corresponding two rotating rods 1054 to flip, preventing them from affecting the normal placement of the cooling fan into the fan mounting seat 4. At the same time, one side of the cooling fan is located in the guide groove 502 and is rollingly connected to several guide wheels 503. When the external lifting device places the cooling fan into the fan mounting seat 4, the magnet plate 104 slides relative to the outer wall of the cooling fan, and the cooling fan is guided by several guide wheels 503, thereby conveniently and accurately placing the cooling fan for the diesel generator into the fan mounting seat 4.
