Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a rain-proof generator set. Background Technique

[0002] A temporary generator set refers to a generator set set up to meet temporary power demands. These generator sets are usually used in places without a stable power supply, such as construction sites, field exploration sites, emergency rescue occasions, and large event sites, etc.

[0003] Since these temporary generator sets are set up and used temporarily, there is a need for rain protection. Generally, such temporary generator sets in the prior art use their own shells for rain protection. However, due to the heat dissipation requirements of such temporary generator sets, a large number of heat dissipation holes are opened on the surface of the shell. In this way, when it rains heavily and there is wind, rainwater easily enters the interior of the shell of the temporary generator set through the heat dissipation holes of the shell, which is likely to affect the service life of the entire temporary generator set. Therefore, in view of this problem, a rain-proof generator set is needed for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rain-proof generator set to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rain-proof generator set, including a generator set body, a rain-proof mechanism for rain protection is arranged at the upper end of the generator set body. The rain-proof mechanism includes a fixed block, a screw rod, a connection box, a connection shaft, a winding drum, and a rain-proof cloth. Fixed blocks are fixedly arranged on both sides of the middle part of the upper end of the generator set body. A screw rod is movably arranged between the fixed blocks through bearings. Connection boxes are fixedly arranged on both sides of the upper end of the generator set body. A connection shaft is movably arranged inside the connection box through a bearing. A winding drum is fixedly arranged on the outer surface of the connection shaft. A rain-proof cloth is wound around the outer surface of the winding drum. A transmission mechanism for driving the rain-proof cloth to unfold is arranged between the screw rod and the rain-proof cloth.

[0006] Preferably, the transmission mechanism includes a transmission block, a transmission rod, and a cross bar. Transmission blocks are movably sleeved on both sides of the surface of the screw rod through threads. Transmission rods are movably arranged on both sides of the surface of the transmission block through rotating shafts. A cross bar is fixedly arranged at one end of the rain-proof cloth away from the winding drum. One end of the transmission rod away from the transmission block is movably connected to the cross bar through a rotating shaft. Through the transmission mechanism, the rain-proof cloth on both sides of the generator set body can be simultaneously pushed to unfold, which can effectively prevent the inclined rainwater from entering the interior of the generator set body through the heat dissipation holes of the generator set body.

[0007] Preferably, a box door is movably provided on the outer surface of the generator set body via a hinge, and a heat dissipation slot is provided on the outer surface of the box door, so that the normal heat dissipation demand inside the generator set body can be guaranteed through the heat dissipation slot.

[0008] Preferably, the threads on both sides of the screw surface are opposite, and an electric motor is fixedly provided on the outer surface of the fixed block on one side. The output shaft end of the motor is transmission-connected to the screw via a coupling, so that the screw can be conveniently driven to rotate by the motor, thereby driving the transmission block to move by the thread. Since the threads on both sides of the screw surface of this device are opposite, the two transmission blocks can be driven to move in opposite directions when the screw rotates.

[0009] Preferably, a fixed base is fixedly provided at the lower end of the generator set body, and the fixed base can be used to conveniently fix the entire device at a target position.

[0010] Preferably, a reset torsion spring is provided between the outer surface of the connection box and the connection shaft, and the reset torsion spring can automatically drive the connection shaft and the winding roller to rotate and reset, so that the winding roller can wind the rain shield cloth and store it inside the connection box.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model drives the screw to rotate by the motor, so that the screw with opposite threads on both sides of the surface can drive the two transmission blocks to move in opposite directions. At this time, the transmission rod can push the rainproof cloth wound on the outer surface of the winding drum to unfold, and finally the rainproof cloth can be Figure 1 become Figure 2 In the state shown, the rain shield is extended a little, which can effectively prevent the generator body from slanting rainwater from entering the generator body through the heat dissipation holes of the generator body when it rains, thus protecting the generator body.

[0013] 2. When the rain shield is not needed, the utility model drives the screw rod to rotate in the opposite direction through the motor, so that the transmission rod no longer stretches the rain shield. At this time, the rain shield can be automatically wound and stored inside the connecting box under the action of the torsion spring, so that the volume of the whole device is minimized, which can facilitate subsequent transportation, lifting and other operations.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a rainproof generator set, including a generator set body 1, a rainproof mechanism for rainproof is arranged at the upper end of the generator set body 1, the rainproof mechanism includes a fixed block 2, a screw 3, a connection box 4, a connection shaft 5, a winding drum 6, and a rainproof cloth 7. Fixed blocks 2 are fixedly arranged on both sides of the middle part of the upper end of the generator set body 1, a screw 3 is movably arranged between the fixed blocks 2 through a bearing, connection boxes 4 are fixedly arranged on both sides of the upper end of the generator set body 1, a connection shaft 5 is movably arranged inside the connection box 4 through a bearing, a winding drum 6 is fixedly arranged on the outer surface of the connection shaft 5, and a rainproof cloth 7 is wound around the outer surface of the winding drum 6. A transmission mechanism for driving the rainproof cloth 7 to unfold is arranged between the screw 3 and the rainproof cloth 7.

[0020] The transmission mechanism includes a transmission block 8, a transmission rod 9, and a cross bar 10. Transmission blocks 8 are movably sleeved on both sides of the surface of the screw 3 through threads, transmission rods 9 are movably arranged on both sides of the surface of the transmission block 8 through rotating shafts, a cross bar 10 is fixedly arranged at one end of the rainproof cloth 7 away from the winding drum 6, and one end of the transmission rod 9 away from the transmission block 8 is movably connected to the cross bar 10 through a rotating shaft. Through the transmission mechanism, the rainproof cloths 7 on both sides of the generator set body 1 can be simultaneously pushed to unfold, so as to effectively prevent the inclined rainwater from entering the inside of the generator set body 1 through the heat dissipation holes of the generator set body 1;

[0021] A box door 11 is movably arranged on the outer surface of the generator set body 1 through a hinge, and heat dissipation slots 12 are opened on the outer surface of the box door 11. Through the heat dissipation slots 12, the normal heat dissipation requirements inside the generator set body 1 can be ensured;

[0022] The threads on both sides of the surface of the screw 3 are opposite, and a motor 15 is fixedly arranged on the outer surface of the fixed block 2 on one side. The output shaft end of the motor 15 is connected to the screw 3 through a coupling. The motor 15 can easily drive the screw 3 to rotate, so that the transmission block 8 can be driven to move through the thread. Since the threads on both sides of the surface of the screw 3 are opposite, the device can drive the two transmission blocks 8 to move in opposite directions when the screw 3 rotates.

[0023] The lower end of the generator body 1 is fixedly provided with a fixed base 13, through which the whole device can be conveniently fixed and installed at the target position;

[0025] Working principle: When using this device, it is used as a temporary generator set and can be transported to various construction sites for use. During normal use, the rainproof cloth 7 is wound and stored inside the connection box 4, so that the volume of the entire device is minimized and will not be a hindrance, and transportation and movement are also relatively convenient. If it rains and needs to be shielded from rain to prevent rainwater from entering the generator set body 1 from the heat dissipation slot 12, the screw 3 can be driven to rotate by the motor 15, so that the screw 3 with opposite threads on both sides of the surface can be driven to drive the two transmission blocks 8 to move in opposite directions. At this time, the transmission rod 9 can push the rainproof cloth 7 wound on the outer surface of the winding drum 6 to unfold, and finally it can be Figure 1 become Figure 2 In the state shown, the rain shield 7 is extended a little, which can effectively prevent the generator body 1 from being slanted and rainwater from entering the generator body 1 through the heat dissipation holes of the generator body 1 when it rains, thereby protecting the generator body 1;

[0026] When the rain shield 7 is not needed, the motor 15 drives the screw 3 to rotate in the opposite direction, so that the transmission rod 9 no longer holds the rain shield 7 open. At this time, the rain shield 7 can be automatically wound and stored in the connecting box 4 under the action of the torsion spring, so that the volume of the entire device is minimized, which can facilitate subsequent transportation, lifting and other operations.
