DETAILED DESCRIPTION

[0028] The present application is described in detail below with reference to the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of the present application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in the present application without creative effort are also within the scope of protection of the present application.

[0029] The present application provides an overload monitoring device based on power load monitoring as shown in Figures 1-5, including a main bracket 1, a universal wheel 2 is installed at the bottom of the main bracket 1, an operating table 3 is provided on the top of the main bracket 1, a first interface 4 is provided on one side of the top of the operating table 3, and a second interface 5 is provided on the other side; a glasses-shaped groove 6 is opened on the top of the operating table 3, and semicircular grooves 7 are provided on the front and rear sides of the glasses-shaped groove 6, and a plug rod 8 is provided inside the semicircular groove 7, a monitoring line device 9 is provided inside the glasses-shaped groove 6, and a cover plate 10 matching the glasses-shaped groove 6 is provided on the top of the monitoring line device 9.

[0030] When monitoring the power load of the wind turbine, the monitoring line device 9 can be quickly moved out from the inside of the operating table 3, and after quickly separating the wound cable, the monitoring line device 9 can be rotated 90 degrees to align it with the two semicircular grooves 7, and connected to the first interface 4 and the second interface 5. Finally, the operating table 3 is manipulated to monitor the power load. The monitoring line device 9 can then quickly wind up the cable to achieve rapid storage of the monitoring line device 9. Finally, the monitoring line device 9 is enclosed in the operating table 3 through the cover plate 10 to reduce corrosion and improve the accuracy of subsequent monitoring. At the same time, the universal wheels can easily push the operating table 3 to walk on a flat ground, which is convenient for transporting cables.

[0031] Referring to Figures 1-4 of the specification, the monitoring line device 9 includes a telescopic rod 91, a connecting plate 92 is provided on the top of the telescopic rod 91, and a cover plate 10 is fixedly connected to the top of the connecting plate 92. Winding drums 93 are provided at both ends of the connecting plate 92. The top of the winding drum 93 is rotatably connected to the bottom of the connecting plate 92. A signal transmitting cable and a signal receiving cable are respectively provided on the two winding drums 93. The signal transmitting cable matches the first interface 4, and the signal receiving cable matches the second interface 5. When in use, one end of the signal transmitting cable is connected to the first interface 4, and this end is located as a fixed end, and the other end is installed with a sound sensor. One end of the signal receiving cable is connected to the second interface 5, and this end is located as a fixed end, and the other end is installed with a sound receiver. A socket 94 is provided at the bottom of the winding drum 93, and the plug rod 8 matches the socket 94.

[0032] The use process of the monitoring line device 9 is as follows:

[0033] When monitoring is required, the cover plate 10 can be pulled up, thereby driving the connecting plate 92 and the two winding drums 93 at both ends of the connecting plate 92 to move out from the glasses-shaped groove 6 on the top of the operating table 3, and then one end of the signal transmitting cable (i.e., the end on which the sound sensor is installed) and one end of the signal receiving cable (i.e., the end on which the sound receiver is installed) on the two winding drums 93 can be pulled respectively, so that the end connecting the sound sensor and the sound receiver gradually becomes longer until it reaches the power load that needs to be monitored, and the connecting plate 92 is rotated 90 degrees so that the two winding drums 93 are aligned with the two semicircular grooves 7 respectively, and the insertion rod 8 is inserted into the socket 94 at the bottom of the winding drum 93, and then the other end of the signal transmitting cable (i.e., the fixed end of the signal transmitting cable) and the other end of the signal receiving cable are aligned. The outer end (i.e., the fixed end of the signal receiving cable) is respectively connected to the first interface 4 and the second interface 5, and the operating console 3 is operated for monitoring. When it is necessary to move to a nearby power load device, there is no need to place the winding drum 93 into the eyeglass-shaped groove 6. The cover plate 10 can be rotated to rotate the two winding drums 93 at the same time, so that the signal transmitting cable and the signal receiving cable are wound on the two winding drums 93 at the same time, which can make the winding amplitude of the signal transmitting cable and the signal receiving cable larger and improve the winding efficiency; when the monitoring is completed, the signal transmitting cable and the signal receiving cable can be respectively wound on the corresponding winding drums 93 and put back into the eyeglass-shaped groove 6. The signal transmitting cable and the signal receiving cable made of filamentous material have a fast rate of repeated release and re-storage.

[0034] Referring to Figures 1, 2 and 5 of the specification, a support device 11 is provided on the top of the operating table 3. The support device 11 includes two vertical rods 111. The spacing between the two vertical rods 111 is greater than the diameter of the winding drum 93 to ensure that the winding drum 93 is not affected when rotating around the telescopic rod 91. The two vertical rods 111 are respectively located between the semicircular groove 7 and the glasses-shaped groove 6 on the front side and between the semicircular groove 7 and the glasses-shaped groove 6 on the rear side. The vertical rods 111 are plugged into the top of the operating table 3 and a support spring is provided at the bottom. 112. A support tube 113 is sleeved on the outside of the vertical rod 111, and a horizontal plate 114 is fixedly connected to the outer cylindrical surface of the support tube 113; a clamping rod 115 is fixedly connected to the front and rear sides of the vertical rod 111, and the top surface of the horizontal plate 114 is higher than the top surface of the support tube 113. The top of the horizontal plate 114 has an arc-shaped surface so that the clamping rod 115 fits on the arc-shaped surface to prevent the clamping rod 115 from loosening at the top of the horizontal plate 114, and the height of the clamping rod 115 is between the height of the top surface of the horizontal plate 114 and the height of the top surface of the support tube 113.

[0035] When the monitoring line device 9 is stored inside the glasses-shaped groove 6 again, the horizontal plate 114 can be rotated to the top surface of the cover plate 10. When the height of the clamping rod 115 is between the height of the top surface of the horizontal plate 114 and the height of the top surface of the support tube 113, the vertical rod 111 is pulled up until the height of the clamping rod 115 is higher than the horizontal plate 114. When the horizontal plate 114 is rotated to just below the clamping rod 115, the vertical rod 111 is released. Under the action of the restoring force of the support spring 112, the clamping rod 115 presses down on the horizontal plate 114, thereby making the horizontal plate 114 have a better clamping effect on the cover plate 10. When the bottom of the winding drum 93 enters the semicircular groove 7, the horizontal plate 114 can also be fixed to the winding drum 93 in the above manner.

[0036] When the monitoring line device 9 is pulled up from the inside of the glasses-shaped groove 6, the two winding drums 93 are rotated 90 degrees and aligned with the two semicircular grooves 7. When the two winding drums 93 are lowered, the connecting plate 92 will first be squeezed on the vertical rod 111. The support spring 112 at the bottom end of the vertical rod 111 can play a supporting role, reducing the impact force between the winding drum 93 and the semicircular groove 7.

[0037] Referring to Figures 1 and 5 of the specification, the same support plate 12 is provided at the top of the two vertical rods 111, and two needle rods are provided at the bottom of the support plate 12, which are respectively inserted into the top of the two vertical rods 111. A rotating rod connected by a bearing is inserted at the center of the top of the support plate 12, and a U-shaped card 13 is provided at the top of the rotating rod. The width of the inner side of the U-shaped card 13 is the same as the width of the connecting plate 92 in the front-to-back direction.

[0038] When rotating the connecting plate 92, if one hand controls the cable, the other hand cannot continuously rotate the connecting plate 92. Therefore, a U-shaped card 13 and a support plate 12 are provided. When the connecting plate 92 needs to be rotated to rotate the two winding drums 93, the connecting plate 92 can be stuck in the U-shaped card 13, and then the U-shaped card 13 can be rotated with one hand to drive the two winding drums 93 to rotate. Then the U-shaped card 13 can be put down, and the support plate 12 supports the connecting plate 92. After adjusting the hand posture, the connecting plate 92 can be continued to be rotated, thereby realizing single-handed rotation and improving the winding efficiency.

[0039] For example, when the monitoring line device 9 is pulled up from the inside of the eyeglass-shaped groove 6, the support plate 12 has not yet been inserted into the two vertical rods 111. When the monitoring line device 9 rises to a certain height (even if the connecting plate 92 is higher than the top of the vertical rod 111), the support plate 12 is inserted into the two vertical rods 111 through the two needle rods set at the bottom thereof, wherein a rotating rod connected by a bearing is inserted at the top center of the support plate 12, and a U-shaped card 13 is provided at the top of the rotating rod. Then, the connecting plate 92 is clamped in the U-shaped card 13, so that the two winding drums 93 can be driven to rotate by rotating the U-shaped card 13 with one hand.

[0040] 1 of the specification, a storage box 14 is provided at the rear side of the operating table 3 , and a sponge pad is provided at the bottom inside the storage box 14 .

[0041] When not in use, some parts can be placed in the storage box 14, or the support plate 12 can be removed from the top of the vertical rod 111 and then placed in the storage box 14. The sponge pad can protect the parts placed in the storage box 14.

[0042] 1 and 2 of the specification, a pull ring 15 is provided at the top center of the cover plate 10 .

[0043] The pull ring 15 can be used to conveniently lift the cover plate 10 out of the glasses-shaped groove 6 .

[0044] 1 of the specification, a sealing ring 16 is provided at the edge of the cover plate 10 , and a plurality of grooves are formed at the bottom of the sealing ring 16 .

[0045] The sealing ring 16 can improve the sealing effect of the cover plate 10 on the glasses-shaped groove 6. At the same time, a plurality of grooves are provided at the bottom of the sealing ring 16, which can facilitate the deformation of the bottom of the sealing ring 16 when the sealing ring 16 is inserted into the glasses-shaped groove 6, thereby making it easier to enter the glasses-shaped groove 6.

[0046] 1 of the specification, handles 17 are provided on both sides of the operating table 3 , and the handles 17 are slidably connected to the side surfaces of the operating table 3 .

[0047] The handle 17 can be used to move the operating table 3 to other locations conveniently, and since the handle 17 is slidably connected to the side of the operating table 3 and can be moved vertically, when the moved operating table 3 is put down, the handle 17 can be moved vertically. When the operating table 3 touches the ground, the person's hand can move downward together with the handle 17 as the person continues to move downward until the person realizes that the operating table 3 has touched the ground, thereby avoiding the discomfort of pressing down on the fixed handle 17 when the hand continues to move downward.

[0048] 5 of the specification, the bottom end of the support spring 112 is fixedly connected to the inside of the operating table 3 , the top end of the support spring 112 is fixedly connected to a threaded block 18 , and the threaded block 18 is threadedly connected to the bottom end of the vertical rod 111 .

[0049] The arrangement of the threaded block 18 facilitates the connection between the vertical rod 111 and the support spring 112 .

[0050] Example 2:

[0051] The present application also discloses a method for overload monitoring equipment based on power load monitoring, which is characterized by comprising the following steps S1-S4.

[0052] S1: When monitoring is required, the two winding reels 93 are removed from the glasses-shaped groove 6 on the top of the operating table 3.

[0053] S2: Then, one end of the signal transmitting cable and one end of the signal receiving cable on the two winding drums 93 can be pulled respectively, so that the end connecting the sound sensor and the sound receiver gradually becomes longer until it reaches the power load that needs to be monitored.

[0054] S3: Align the two winding drums 93 with the two semicircular grooves 7 respectively, and insert the insertion rod 8 into the socket 94 at the bottom of the winding drum 93, then connect the other end of the signal transmitting cable and the other end of the signal receiving cable to the first interface 4 and the second interface 5 respectively, and operate the operating console 3 for monitoring.

[0055] S4: When it is necessary to move to a nearby power load device, there is no need to put the winding drum 93 into the glasses-shaped groove 6. The cover plate 10 can be rotated to rotate the two winding drums 93 at the same time, so that the signal transmitting cable and the signal receiving cable are wound on the two winding drums 93 at the same time.

[0056] The above is a detailed introduction to the overload monitoring device and method based on power load monitoring provided by this application. For general technical personnel in this field, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope.
