Description

Technical Field

[0001] The utility model relates to the field of small generators, in particular to a safe outdoor generator set. Background Art

[0002] Currently, the demand for small backup generator sets is increasing, especially in some scenarios where outdoor operations require electricity. Since it is often difficult to connect to the power grid when electricity is needed outdoors, independent diesel (gasoline) generator sets are needed as a power source.

[0003] When a small diesel generator is used outdoors, it may cause a fire due to a short circuit in the electrical circuit or a fuel leak. Unsafe electrical grounding and maintenance may also lead to electric shock accidents.

[0004] Diesel generator sets may experience fuel leakage or unsafe electrical grounding. In addition to damage to the diesel generator set itself, another important reason is the vibration of the diesel generator set during operation, which causes the generator set to shift or even tilt, thus causing fuel leakage. The grounding device may also become unsafe due to the vibration and displacement of the generator set. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a safe outdoor generator set to solve the technical problems in the prior art.

[0006] Based on the above objectives, the present invention provides an outdoor safety generator set, comprising a generator body and a base plate fixedly connected to the bottom of the generator body, characterized in that the generator set further comprises:

[0007] A fixing screw passing through the base plate and threadedly connected thereto is used to fix the generator body and the base plate to the ground, and a connecting gear is fixedly connected to the top of the fixing screw;

[0008] A non-return gear rotatably connected to the base plate can be engaged with the connecting gear to prevent the connecting gear from rotating in the reverse direction.

[0009] Furthermore, the upper end of the connecting gear is fixedly connected to a connecting piece, which is provided with a horizontal through hole, and a driving rod is slidably connected in the through hole, and both ends of the driving rod are provided with expansion parts with a diameter larger than the inner diameter of the through hole.

[0010] Furthermore, a universal wheel is provided at the lower end of the base plate, and a cone head is provided at the lower end of the fixing screw.

[0011] Furthermore, an auxiliary grounding ring connected to the metal shell of the generator body is provided in the base plate. The auxiliary grounding ring is sleeved on the outside of the fixing screw and threadedly connected thereto for cooperating with the fixing screw for grounding.

[0023] Specific implementation and principle

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0026] The first aspect of the present invention is as follows Figure 1 、 Figure 2 and Figure 3 As shown, the present invention further incorporates a base plate 102, universal wheels 103, a fixing mechanism, and an auxiliary grounding mechanism on the basis of the existing generator body 101. The base plate 102 is fixedly connected to the bottom of the generator body 101, and the universal wheels 103 are located at the lower end of the base plate 102, making it easy to carry and move, and convenient for outdoor use.

[0027] The key point is the fixing mechanism used to secure the generator body 101 and base plate 102 to the ground. This fixing mechanism primarily consists of a fixing screw 104 that passes through base plate 102 and is threadedly connected thereto. A connecting gear 105 is also fixedly connected to the top of fixing screw 104. Furthermore, a connecting member 106 is fixedly connected to the top of connecting gear 105. Connecting member 106 has a horizontal through-hole formed in it, and a drive rod 107 is slidably connected to this through-hole. Both ends of drive rod 107 have expansion portions with a diameter larger than the inner diameter of the through-hole.

[0028] The fixing mechanism can be provided in one or more groups. When in use, the generator body 101 and base plate 102 are first moved to a suitable location. Then, the drive rod 107 is rotated to rotate the fixing screw 104, causing the fixing screw 104 to drill into the ground, thereby fixing the generator body 101 and base plate 102. When the drive rod 107 is rotated, the position of the drive rod 107 can be adjusted by sliding, thereby adjusting the position of the force point and the connection member 106 (fulcrum), which saves the user effort and makes it easier to drill the fixing screw 104 deeper into the ground.

[0029] Preferably, a cone head is provided at the lower end of the fixing screw 104 to facilitate the fixing screw 104 to be drilled into the ground.

[0030] The expansion portions at both ends of the driving rod 107 or the stoppers whose size is larger than the inner diameter of the through hole play a role in preventing the driving rod 107 from being separated from the connecting member 106 .

[0031] On the other hand, Figure 4 As shown, an auxiliary grounding ring 114 is provided within base plate 102 and connected to the metal casing of generator body 101. Auxiliary grounding ring 114 is sleeved over and threadedly connected to fixing screw 104, for grounding in conjunction with fixing screw 104. Generator body 101's original grounding device normally grounds the auxiliary grounding ring 114, in conjunction with fixing screw 104, serves as a backup grounding device. In the event of a malfunction or incomplete grounding of the original grounding device, fixing screw 104 provides the necessary grounding.

[0032] In order to prevent the diesel generator set from vibrating during operation, causing the generator set to shift or even tilt, which in turn causes fuel leakage, the original grounding device also becomes unsafe due to the vibration of the generator set and the displacement of the generator set.

[0033] A check gear 108 is provided on the base plate 102 and is rotatably connected to the base plate 102. The check gear 108 can mesh with the connecting gear 105 at the top of the fixing screw 104 to prevent the connecting gear 105 from rotating in the opposite direction. This prevents the fixing screw 104 from rotating in the opposite direction and eventually coming off the ground due to vibration of the diesel generator set, and prevents the generator body 101 and the base plate 102 from shifting on the ground due to the fixing screw 104 coming off the ground.

[0034] Specifically, such as Figure 4As shown, the base plate 102 is further provided with an inner groove 109, in which a ratchet 110 is rotatably connected. The ratchet 110 is fixedly connected to the check gear 108 via a connecting rod. A pawl 111 is further provided in the inner groove 109 for engaging with the ratchet 110. Due to the restriction of the pawl 111, the ratchet 110 and the check gear 108 can only rotate in one direction. Since the check gear 108 can mesh with the connecting gear 105 at the top of the fixed screw 104, after meshing, the fixed screw 104 can also only rotate in one direction (the direction opposite to drilling into the ground).

[0035] Therefore, the vibration during operation of the diesel generator set will only cause the fixing screw 104 to drill deeper into the ground, thereby making the generator body 101 and the base plate 102 more firmly fixed to the ground and making the grounding of the generator body 101 more complete.

[0036] After the generator body 101 is used, the fixing screw 104 needs to be pulled out to allow the generator body 101 and the base plate 102 to move. First, the ratchet 110 and the pawl 111 need to be disengaged so that the pawl 111 no longer restricts the ratchet 110 from rotating in reverse.

[0037] Therefore, a telescopic spring 112 is provided in the inner groove 109 to which the pawl 111 is movably connected. The upper and lower ends of the telescopic spring 112 are respectively connected to the bottom of the pawl 111 and the bottom of the inner groove 109. A telescopic column 113 is also slidably connected to the base plate 102, and the bottom end of the telescopic column 113 is fixedly connected to the pawl 111.

[0038] Therefore, one only needs to step on the telescopic column 11 to lower the pawl 111 and disengage the ratchet 110, and then reversely rotate the driving rod 107 to reversely rotate the fixing screw 104 to lift the fixing screw 104 out of the ground. Finally, after the fixing screw 104 is out of the ground, the universal wheel 103 can be used to move the generator body 101 away. DETAILED DESCRIPTION

[0039] During use, the generator body 101 and base plate 102 are first moved to a suitable location using the universal wheels 103. The drive rod 107 is then rotated to rotate the fixing screw 104, causing it to drill into the ground, thereby securing the generator body 101 and base plate 102. As the drive rod 107 is rotated, its position can be adjusted by sliding, thereby adjusting the force point and the position of the connector 106. This reduces user effort and makes it easier to drill the fixing screw 104 deeper into the ground.

[0040] After being drilled into the ground, the fixing screw 104 not only fixes the generator body 101 and the base plate 102 , but also cooperates with the auxiliary grounding ring 114 to serve as a backup grounding.

[0041] When the diesel generator set is working, the vibration can easily cause the fixed screw 104 to rotate. However, since the fixed screw 104 rotates deeper into the ground when it rotates forward, the ratchet 110 is restricted by the pawl 111, and the ratchet 110 can only rotate in one direction with the check gear 108. Therefore, after the check gear 108 engages with the connecting gear 105 at the top of the fixed screw 104, the fixed screw 104 can only rotate in the forward direction.

[0042] After the generator body 101 is finished using, the fixing screw 104 needs to be removed to allow the generator body 101 and base plate 102 to be moved. To do this, the ratchet 110 and pawl 111 must first be disengaged, so that the pawl 111 no longer restricts the ratchet 110 from rotating. To do this, simply depress the telescopic column 11, causing the pawl 111 to descend and disengage from the ratchet 110. Then, reverse the rotation of the drive rod 107 to rotate the fixing screw 104 in the opposite direction, lifting it out of the ground. Finally, once the fixing screw 104 is free of the ground, the generator body 101 can be moved away using the universal wheel 103.

[0043] Based on the above, the present invention sets a base plate 102 at the bottom of the generator body 101, and sets a universal wheel 103 at the lower end of the base plate 102, which is convenient for carrying and transferring, and convenient for outdoor use. In addition, a fixing screw 104 with a cone head at the lower end is set on the base plate 102, which is drilled into the ground to fix the generator body 101, thereby preventing the generator body 101 from shifting due to vibration during operation. An auxiliary grounding ring 114 connected to the fixing screw 104 is also provided in the base plate 102, and the auxiliary grounding ring 114 is connected to the metal shell of the generator body 101. As an auxiliary grounding device provided in addition to the original grounding device, grounding is further ensured. A check gear 108 is provided on the base plate 102 to prevent the connecting gear 105 from rotating in the reverse direction. Therefore, the vibration of the motor body 101 will only cause the fixing screw 104 to rotate forward deeper into the ground, and will not rotate in the reverse direction and leave the ground. This ensures a secure connection and complete grounding.
