[0018] The embodiment of the present invention provides a generator operation monitoring device, such as Figure 1-Figure 3 and Figure 5 As shown, it includes: a detector 4, a shell and a retractable pulley assembly 7.

[0019] The detector 4 is installed in the shell, and the shell can protect the detector 4.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, the storable pulley assembly 7 includes a slide rod 71, a slider 72 and a pulley 74, and a placement groove 75 is provided in the shell for accommodating the pulley 74; the slide rod 71 is fixedly connected to the shell, and one end of the slide rod 71 extends into the placement groove 75, the slider 72 is slidably installed on the slide rod 71, and the pulley 74 is installed on the slider 72.

[0021] The slider 72 can reciprocate between the working position and the storage position when sliding along the slide bar 71. Figure 2 As shown in the figure, the pulley 74 is located outside the placement groove 75 and can roll along the ground, so as to slide and move the generator operation monitoring device, which is convenient for transportation; when the slider 72 slides along the slide bar 71 to the storage position, the slider 72 and the pulley 74 are stored in the placement groove 75, so as to place and store the generator monitoring device after use, and prevent dust and the like from falling on the pulley 74 during the storage process. In addition, the pulley 74 is stored in the placement groove 75, so as to prevent the pulley 74 from being stained with dirt such as lubricating oil when the generator monitoring device is monitoring, thereby avoiding cleaning the pulley 74 at the monitoring site and saving manpower and material resources.

[0022] By providing a retractable pulley assembly 7, the pulley 74 can be stored in the placement groove 75 when the pulley 74 is not in use. For the generator monitoring device used in the overseas oil field self-contained power station, when it is finished using or during replacement, maintenance and transportation, the slider 72 and the pulley 74 can be stored in the placement groove 75 or the pulley 74 can be placed outside the placement groove 75, which is convenient to use.

[0023] In an exemplary embodiment, Figure 1-Figure 3 and Figure 5 As shown, the pulley assembly 7 includes two sliding rods 71 ​​arranged in parallel, and the two sliding rods 71 ​​pass through the slider 72 to better guide the slider 72 to slide.

[0024] In an exemplary embodiment, Figure 5 As shown, the housing includes a first housing wall 15, and the placement groove 75 has a groove opening 78 arranged on the first housing wall 15 of the housing, and the slider 72 and the pulley 74 can enter the placement groove 75 from the groove opening 78. The pulley assembly 7 also includes a sealing plate 77, which is movably mounted on the first housing wall 15 to open or seal the groove opening 78.

[0025] Specifically, a slide groove 76 is further provided on the first shell wall 15, and the sealing plate 77 is slidably mounted on the first shell wall 15 and can slide along the slide groove 76 to open the slot opening 78 (such as Figure 5 As shown), the pulley 74 can be moved outside the placement groove 75 to transport the generator monitoring device, or the pulley 74 can be moved into the placement groove 75 to store the pulley 74; the sealing plate 77 can also slide to seal the groove opening 78 to prevent the pulley 74 from being contaminated by dirt during the monitoring process and to facilitate the placement and storage of the generator monitoring device after use.

[0026] In an exemplary embodiment, Figure 2 and Figure 5 As shown, the sliding rod 71 includes a first rod 711, a second rod 712, a third rod 713 and a fourth rod 714 connected in sequence, and a bending structure is formed between the first rod 711 and the second rod 712, between the second rod 712 and the third rod 713, and between the third rod 713 and the fourth rod 714. The shell also includes a second shell wall 16 adjacent to the first shell wall 15. The first rod 711 is fixedly connected to the outer wall surface of the second shell wall 16, the second rod 712 extends along the second shell wall 16 toward the first shell wall 15, the third rod 713 extends along the first shell wall 15 toward the slot opening 78, and the fourth rod 714 passes through the slot opening 78 and is fixedly connected to the inner wall surface of the placement slot 75.

[0027] When the slider 72 is in the working position, the pulley 74 slides onto the first rod 711. The bending structure between the first rod 711 and the second rod 712 helps prevent the pulley 74 from sliding to the second rod 722 and leaving the working position; when the slider 72 is in the storage position, the slider 72 slides onto the fourth rod 714.

[0028] Specifically, the generator operation monitoring device is placed horizontally during monitoring and placed vertically during transportation. Taking the state of the generator operation monitoring device during monitoring as a reference, the first shell wall 15 is the bottom wall of the shell, the second shell wall 16 is the right wall (or left wall) of the shell, the bottom wall of the shell is provided with a slot opening 78 and a slide slot 76, the first rod 711 of the slide rod 71 is perpendicular to the right wall (or left wall) of the shell and is fixedly connected to the outer wall surface of the right wall (or left wall) of the shell, the second rod 712 extends downward, the third rod 713 is located below the bottom wall of the shell and extends to the left (or right), and the fourth rod 714 extends upward through the slot opening 78 and is fixedly connected to the inner wall surface of the placement slot 75 (such as the upper inner wall surface of the placement slot 75). The slider 72 can slide along the first rod 711, the second rod 712, the third rod 713 and the fourth rod 714 in sequence to be received in the placement groove 75, and can move in the opposite direction along the fourth rod 714, the third rod 713, the second rod 712 and the first rod 711 in sequence. When the slider 72 moves to the first rod 711, it is in the working position. When in the working position, the pulley 74 protrudes from the first rod 711 so that the pulley 74 slides along the ground to prevent the first rod 711 from contacting the ground.

[0029] The sealing plate 77 is located below the first shell wall 15, and a sliding portion is provided on the sealing plate 77 that cooperates with the slide groove 76. The sliding portion passes through the slide groove 76 and can drive the sealing plate 77 to slide along the slide groove 76 from left to right (or from right to left) so that the sealing plate 77 seals the groove opening 78 from below, and can also drive the sealing plate 77 to slide along the slide groove 76 from right to left (or from left to right) to open the groove opening 78, so that the sliding rod 71 does not interfere with the movement of the sealing plate 77.

[0030] In an exemplary embodiment, Figure 5 As shown, the sealing plate 77 is provided with a limiting groove 79 . When the sealing plate 77 seals the groove opening 78 , the limiting groove 79 is plugged and matched with the fourth rod 714 .

[0031] Specifically, two limiting grooves 79 are provided on the right side (or left side) of the sealing plate 77. When the sealing plate 77 seals the groove opening 78, the two limiting grooves 79 can be respectively plugged and matched with the fourth rods 714 of the two sliding rods 71 ​​to limit the sealing plate 77 so that the sealing plate 77 can just seal the groove opening 78; when the sealing plate 77 opens the groove opening 78, the two limiting grooves 79 can be respectively separated from the fourth rods 714 of the two sliding rods 71.

[0032] In an exemplary embodiment, Figure 1 and Figure 2As shown, the pulley assembly 7 also includes a first elastic pin 73, which is installed on the slider 72. A first pin groove is opened on the outer wall surface of the shell. The first elastic pin 73 can be plugged into the first pin groove to fix the slider 72 in the working position. The first elastic pin 73 can also be separated from the first pin groove to allow the slider 72 to slide along the slide rod 71.

[0033] Specifically, a first pin shaft groove (not shown) is provided on the outer wall surface of the second shell wall 16 of the housing, and the size of the first pin shaft groove is adapted to the size of the first elastic pin shaft 73; the first elastic pin shaft 73 passes through the slider 72 and can be elastically retracted. When the slider 72 is in the working position, the first elastic pin shaft 73 is plugged and matched with the first pin shaft groove under the action of its own elastic force to limit and fix the slider 72 in the working position; when the slider 72 needs to be moved, the first elastic pin shaft 73 is pulled outward to separate the first elastic pin shaft 73 from the first pin shaft groove, so that the slider 72 moves along the slide rod 71.

[0034] In an exemplary embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the housing includes a bottom shell 1 and an upper cover 3, the upper cover 3 covers the bottom shell 1, and the detector 4 is fixedly installed in the bottom shell 1. The generator operation monitoring device also includes a stabilizing component 5 installed on the upper cover 3, the stabilizing component 5 includes an elastic member and a pressing plate 54, the two ends of the elastic member are respectively in contact with the upper cover 3 and the pressing plate 54, and the pressing plate 54 presses the detector 4 under the elastic force of the elastic member.

[0035] The pressure plate 54 is firmly attached to the upper surface of the detector 4 under the elastic force of the elastic member, pressing the detector 4, avoiding the shaking of the detector 4 due to transportation, and reducing the possibility of the detector 4 shaking and colliding with the shell and being damaged. The setting of the elastic member ensures that the pressure plate 54 presses the detector 4 tightly, while preventing the pressure of the pressure plate 54 from being too high and damaging the detector 4.

[0036] In an exemplary embodiment, Figure 4 As shown, the stabilizing assembly 5 also includes a sleeve 51 and a piston rod 52. The sleeve 51 is fixed on the upper cover 3. One end of the piston rod 52 extends into the sleeve 51, and the other end is connected to the pressure plate 54. The piston rod 52 can move back and forth along the sleeve 51, and the elastic member is sleeved outside the piston rod 52.

[0037] Specifically, the elastic member is a spring 53, and in the stabilizing assembly 5, there are two sleeves 51, two piston rods 52 and two springs 53, the two sleeves 51 are respectively fixed on the left and right sides of the upper cover 3, the upper ends of the two piston rods 52 are respectively extended into the two sleeves 51, and the lower ends are respectively fixedly connected to the left and right sides of the pressure plate 54, the two springs 53 are respectively sleeved outside the two piston rods 52, and the upper and lower ends of the springs 53 are respectively abutted against the lower wall surface of the upper cover 3 and the upper surface of the pressure plate 54.

[0038] When the piston rod 52 moves along the sleeve 51, it can guide the movement of the pressure plate 54. The arrangement of the two sleeves 51, the piston rod 52 and the spring 53 can provide better guidance for the pressure plate 54, so that the left and right sides of the pressure plate 54 are evenly stressed, so that the pressing force on the detector 4 is balanced.

[0039] In an exemplary embodiment, Figure 1 , Figure 3 and Figure 5 As shown, a slot 11 is provided on the third shell wall 17 of the bottom shell 1, and an insert block 31 is provided on the upper cover 3. The insert block 31 can be plugged into and matched with the slot 11. A second elastic pin 12 is provided on the slot wall of the slot 11, and a second pin slot 32 is provided on the insert block 31. The second elastic pin 12 can be plugged into and matched with the second pin slot 32 to fix the insert block 31 in the slot 11, and the second elastic pin 12 can also be separated from the second pin slot 32 to separate the insert block 31 from the slot 11.

[0040] After the plug block 31 is plugged into the slot 11, the elastically retractable second elastic pin 12 can be plugged into the slot 11 under the action of its own elastic force, so that the plug block 31 is fixed in the slot 11, and then the upper cover 3 and the bottom shell 1 are fixed, which is conducive to the stabilizing component 5 installed on the upper cover 3 to provide a clamping force for the detector 4 in the bottom shell 1 to prevent the detector 4 from shaking or colliding during the transportation of the generator operation monitoring device; when monitoring is carried out, the second elastic pin 12 can be pulled outward to separate the second elastic pin 12 from the second pin groove 32. At this time, the plug block 31 can be separated from the slot 11, so that the upper cover 3 can be lifted to expose the detector 4 so that the detector 4 can monitor the generator.

[0041] Specifically, the rear side of the upper cover 3 is rotatably connected to the bottom shell 1 through the hinge 2, and the front side of the upper cover 3 is provided with an insert block 31, and the front wall surface of the insert block 31 is provided with a second pin shaft groove 32. The third shell wall 17 of the bottom shell 1 is a front wall, on which a convex block protruding forward is provided, and a slot 11 is provided on the convex block, and the second elastic pin shaft 12 is provided on the front slot wall of the slot 11, and the size of the second pin shaft groove 32 is adapted to the size of the second elastic pin shaft 12.

[0042] In an exemplary embodiment, Figure 1 and Figure 3As shown, the generator operation monitoring device further includes a heat dissipation component 6 installed on the upper cover 3 , and the heat dissipation component 6 is used to dissipate heat from the detector 4 .

[0043] When the detector 4 is finished being used, since the detector 4 emits heat internally, closing the upper cover 3 immediately will slow down the heat dissipation. At this time, the heat dissipation device is started to improve the heat dissipation of the detector 4.

[0044] In an exemplary embodiment, Figure 1 and Figure 3 As shown, the heat dissipation assembly 6 includes a fan 61, an air inlet pipe 63, an air outlet pipe 62 and an air collecting hood 64. The air inlet of the fan 61 is connected to one end of the air inlet pipe 63, and the other end of the air inlet pipe 63 is connected to the outside of the shell. The air outlet of the fan 61 is connected to one end of the air outlet pipe 62, and the other end of the air outlet pipe 62 is connected to the air collecting hood 64. The air collecting hood 64 is located above the detector 4, and an air outlet hole is opened on the air collecting hood 64.

[0045] Specifically, the fan 61 is a blower, and the air collecting cover 64 is installed on the lower wall surface of the upper cover 3 and corresponds to the position of the detector 4. A plurality of air outlets are arranged on the air collecting cover 64. When the fan 61 is working, the outside air enters the fan 61 through the air inlet pipe 63, and is blown to the detector 4 through the air outlet pipe 62 and the air outlet cover that cooperate with each other, so as to dissipate heat from the detector 4.

[0046] In an exemplary embodiment, Figure 1 and Figure 5 As shown, a handle 13 is provided on the housing to facilitate carrying the generator monitoring device. Specifically, the handle 13 is arranged on the third housing wall (front wall) 17 at the front of the housing.

[0047] In an exemplary embodiment, Figure 3 As shown, the housing is also provided with a pull rod 14, which can cooperate with the pulley 74 to transport the generator monitoring device. Specifically, the pull rod 14 is installed outside the fourth housing wall 18 of the housing, wherein the fourth housing wall 18 is a rear wall opposite to the third housing wall 17.

[0048] The generator monitoring device according to the embodiment of the present invention is described in detail below.

[0049] When the user uses the pull rod 14 to make the pulley 74 slide along the road surface, a large amount of dust and impurities gather on the outer surface of the pulley 74. At this time, the generator monitoring device is placed horizontally, the first elastic pin 73 is pulled out, and the slider 72 is slid so that the slider 72 and the pulley 74 thereon slide along the slide rod 71 to the inside of the placement groove 75; the sealing plate 77 is slid so that the sealing plate 77 covers the groove opening 78 of the placement groove 75 to accommodate the pulley 74 with stains.

[0050] When the upper cover 3 is closed, the plug block 31 is inserted into the slot 11, and the second elastic pin 12 is inserted into the second pin slot 32, and the upper cover 3 is used to perform preliminary tightening of the detector 4. At the same time, the elastic force of the spring 53 causes the piston rod 52 to move along the sleeve 51, and drives the pressure plate 54 to fit firmly on the upper surface of the detector 4, thereby avoiding the shaking of the detector 4 due to transportation and reducing the possibility of the shaking of the detector 4 and the collision with the shell. When the detector 4 is finished using, due to the internal heat dissipation, closing the upper cover 3 immediately will slow down the heat dissipation. At this time, the fan 61 is started, and air is sucked through the air inlet pipe 63, and the air outlet pipe 62 and the wind condenser 64 cooperate with each other to blow air towards the detector 4, thereby improving the heat dissipation of the detector 4.

[0051] Although the embodiments disclosed in the present invention are as above, the contents described are only embodiments adopted to facilitate understanding of the present invention and are not intended to limit the present invention. Any technician in the field to which the present invention belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in the present invention, but the patent protection scope of the present invention shall still be subject to the scope defined in the attached claims.
