Description

Technical Field

[0001] The utility model belongs to the technical field of safety detection, and in particular relates to a power grid detection device for grid-connected testing. Background Art

[0002] In the new energy grid connection test, the auxiliary equipment with the highest failure rate of pump fans is the inverter. The inverter generates huge heat, and the performance index of the cooling fan of the power control cabinet is directly related to the operation index of the inverter and other PLC equipment. In order to ensure that the inverter will not cause accidents due to overheating exceeding the limit, a detection device is required to detect the temperature inside the inverter.

[0003] A power grid detection device for new energy grid connection testing is disclosed in the Chinese patent network CN216746446U, which belongs to the field of safety detection and includes a thermal imager body, which includes a display and a thermal imager lens. The thermal imager lens is arranged on the top of the display and also includes an endoscope lens. The thermal imager lens is electrically connected to the endoscope lens through an infrared transmission optical fiber, and a storage spiral rod is provided on the thermal imager lens.

[0004] In the prior art, a flexible connector is generally stored by winding it around a storage spiral rod and fastening it with a buckle to prevent the flexible connector from detaching by itself, thereby preventing the endoscope lens from being damaged due to shaking, ensuring the accuracy of use of the endoscope lens, and extending the service life of the endoscope lens. In the above document, after the infrared transmission optical cable is wound around the storage spiral rod, the endoscope as a whole is still exposed to the outside, so that when the device as a whole is moved, the endoscope is still easily damaged by bumps.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the problems in the related technology, the utility model proposes a power grid detection device for grid-connected testing to overcome the above technical problems existing in the existing related technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a power grid detection device for grid-connected testing, comprising a thermal imager body, a thermal imager lens is arranged at one end of the thermal imager body, an infrared transmission optical fiber is arranged at one end of the thermal imager lens, a rubber plug is arranged on the outer side of the transmission optical fiber, a first wire collection groove is opened on the outer side of the thermal imager body, a first storage groove is opened on one side of the thermal imager body, a connecting groove is opened between the first wire collection groove and the first storage groove, an endoscope lens is arranged at one end of the transmission optical fiber, and the rubber plug is arranged at the rear end of the endoscope lens.

[0009] Further, a second wire groove is formed at one end of the thermal imager lens, and the other end of the transmission optical fiber is arranged inside the second wire groove. The transmission optical fiber can be wound inside the second wire groove and the first wire groove. Under the restriction of the first wire groove and the second wire groove, the transmission optical fiber is not easily detached from the outside of the thermal imager body.

[0010] Further, a second storage groove is formed at the bottom of the thermal imager body. A handle is rotatably connected inside the second storage groove. A lifting groove is formed at one end of the handle. The handle can be directly rotated into the second storage groove, so that the second storage groove can store the handle. This setting makes it possible that when the whole device is stored, it will not occupy too much space due to the handle.

[0011] Further, a first clamping groove is formed at the bottom of the handle. A first clamping block is clamped inside the first clamping groove. The first clamping block is fixedly connected with the second storage groove. A second clamping groove is formed on the handle. A second clamping block is fixedly connected to one side of the second storage groove. When the handle is inside the storage groove, the second clamping block is clamped inside the second clamping groove. This setting makes it possible that the handle will not rotate out of the storage groove randomly. When the handle rotates out of the storage groove, the first clamping block can be directly clamped inside the first clamping groove, so that the handle will not rotate randomly when the device is held by the handle.

[0012] Further, a display screen is arranged on the top of the thermal imager body.

[0013] The utility model has the following beneficial effects:

[0014] 1. By directly winding the transmission optical fiber inside the second wire groove, and then moving the transmission optical fiber into the first wire groove in sequence, the transmission optical fiber is directly wound outside the thermal imager lens and the thermal imager body with the assistance of the second wire groove and the first wire groove. When winding to a certain extent, the endoscope lens is directly moved into the first storage groove, and at the same time, the rubber plug is directly plugged into the first storage groove. The cooperation between the first storage groove and the rubber plug can complete the all-round covering protection of the endoscope lens, so that the endoscope lens will not collide with the outside when the whole device is moved, thus improving the overall service life of the endoscope lens;

[0015] 2. When using the device, directly rotate the handle through the lifting groove, so that the handle can rotate out from the inside of the second storage groove. At the same time, the second clamping block also directly moves out from the inside of the second clamping groove. When the handle rotates 90°, the first clamping block is directly clamped into the inside of the first clamping groove, so that the operator can hold the thermal imager body through the handle. The setting of the second storage groove enables the second storage groove to store the handle when the device is not in use, so that the handle does not occupy too much space. At the same time, with the mutual cooperation of the first clamping block and the first clamping groove, and the second clamping block and the second clamping groove, the stability of the handle during use and storage can be ensured.

[0016] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figures 1-6 As shown, the utility model is a power grid detection device for grid-connected testing, comprising a thermal imager body 1, a thermal imager lens 2 is arranged at one end of the thermal imager body 1, an infrared transmission optical fiber 3 is arranged at one end of the thermal imager lens 2, a rubber plug 4 is arranged on the outside of the transmission optical fiber 3, a first wire collection groove 5 is opened on the outside of the thermal imager body 1, a first receiving groove 6 is opened on one side of the thermal imager body 1, a connecting groove 7 is opened between the first wire collection groove 5 and the first receiving groove 6, an endoscope lens 8 is arranged at one end of the transmission optical fiber 3, and the rubber plug 4 is arranged at the rear end of the endoscope lens 8.

[0029] When storing the transmission optical fiber 3, the transmission optical fiber 3 is directly wound around the outside of the thermal imager body 1 and placed inside the first receiving groove 5. When the transmission optical fiber 3 is completely wound around the outside of the thermal imager body 1, the endoscope lens 8 is moved to the inside of the first receiving groove 6. As the endoscope lens 8 continues to penetrate deeper into the rubber plug 4, it is directly plugged into the inside of the first receiving groove 6. At the same time, the transmission optical fiber 3 at one end of the rubber plug 4 is moved to the inside of the receiving groove 7.

[0030] In the present utility model, by moving the endoscope lens 8 into the interior of the first storage groove 6 and directly inserting the rubber plug 4 into the interior of the first storage groove 6, the cooperation between the first storage groove 6 and the rubber plug 4 can achieve all-round coverage protection for the endoscope lens 8. Thus, when the whole device is moved, the endoscope lens 8 will not collide with the outside world. Additionally, when the rubber plug 4 is inside the first storage groove 6, it can limit the position of the endoscope lens 8, so that the endoscope lens 8 will not shake inside the first storage groove 6. The above settings ensure the precision of the endoscope lens 8 and significantly improve its service life.

[0031] In addition, during specific application, the rubber plug 4 can be set to a conical shape, and the bottom overall area of the rubber plug 4 is larger than that of the endoscope lens 8. The first storage groove 6 is set to match the shape of the rubber plug 4. This setting ensures that when the rubber plug 4 is inserted into the interior of the first storage groove 6, the rubber plug 4 will not squeeze the endoscope lens.

[0032] In one embodiment, for the above-mentioned thermal imaging lens 2, a second wire storage groove 9 is provided at one end of the thermal imaging lens 2, and the other end of the transmission optical fiber 3 is arranged inside the second wire storage groove 9.

[0033] When winding the transmission optical fiber 3, first wind the transmission optical fiber 3 inside the second wire storage groove 9, and then lead the transmission optical fiber 3 into the interior of the first wire storage groove 5, so that the whole transmission optical fiber 3 is wound inside the first wire storage groove 5 and the second wire storage groove 9.

[0034] The provision of the second wire storage groove 9 makes it difficult for the transmission optical fiber 3 at one end of the thermal imaging lens 2 to break away from one end of the thermal imaging lens 2 under the restriction of the second wire storage groove 9.

[0035] In one embodiment, for the above-mentioned thermal imager body 1, a second storage groove 10 is provided at the bottom of the thermal imager body 1. A handle 11 is rotatably connected inside the second storage groove 10. A lifting groove 12 is provided at one end of the handle 11. A first clamping groove 13 is provided at the bottom of the handle 11. A first clamping block 14 is clamped inside the first clamping groove 13, and the first clamping block 14 is fixedly connected to the second storage groove 10. A second clamping groove 15 is provided on the handle 11, and a second clamping block 16 is fixedly connected to one side of the second storage groove 10.

[0036] When using the device, directly rotate the handle 11 through the lifting groove 12 and make the handle 11 move out of the interior of the second storage groove 10. At this time, the second clamping block 16 moves out of the interior of the second clamping groove 15. When the handle rotates 90°, the first clamping block 14 is directly clamped into the first clamping groove 13, and then the thermal imager body 1 is held by the handle 11.

[0037] The second storage groove 10 can store the handle 11, so that the device will not occupy too much space when not in use. When the handle 11 is inside the first storage groove 6, since the second locking block 16 is locked into the second locking groove 15, the handle 11 is not easily rotated out of the second storage groove 10. When the handle 11 is rotated out, since the first locking block 14 is locked in the first locking groove 13, the handle 11 will not shake during use, thus improving the overall stability of the device.

[0038] A display screen 17 is provided at the top of the thermal imager body 1.

[0039] Through the above technical solutions: 1. By directly winding the transmission optical fiber 3 inside the second wire storage groove 9 and then sequentially moving the transmission optical fiber 3 into the first wire storage groove 5, the transmission optical fiber 3 is directly wound outside the thermal imager lens 2 and the thermal imager body 1 with the assistance of the second wire storage groove 9 and the first wire storage groove 5. When the winding reaches a certain degree, the endoscope lens 8 is directly moved into the first storage groove 6, and at the same time, the rubber plug 4 is directly inserted into the first storage groove 6. The cooperation between the first storage groove 6 and the rubber plug 4 can completely cover and protect the endoscope lens 8, so that the endoscope lens 8 will not collide with the outside when the device is moved as a whole, thus improving the overall service life of the endoscope lens 8; 2. When using the device, the handle 11 is directly rotated through the lifting groove 12, so that the handle 11 can be rotated out of the second storage groove 10, and at the same time, the second locking block 16 also directly moves out of the second locking groove 15. When the handle 11 is rotated 90°, the first locking block 14 is directly locked into the first locking groove 13, so that the operator can hold the thermal imager body 1 through the handle 11. The setting of the second storage groove enables the second storage groove 10 to store the handle 11 when the device is not in use, so that the handle does not occupy too much space. At the same time, with the mutual cooperation of the first locking block 14 and the first locking groove 13, and the second locking block 16 and the second locking groove 15, the stability of the handle 11 during use and storage can be ensured.
