Description
Technical Field
[0001] This utility model relates to the field of power quality assessment technology, and in particular to a smart grid power quality assessment device. Background Technology
[0002] A smart grid is essentially an intelligent power grid, built upon an integrated, high-speed, two-way communication network. It aims to achieve the goals of reliability, security, economy, efficiency, environmental friendliness, and safe operation of the power grid. Within the smart grid field, power quality assessment is required, necessitating the use of smart grid power quality assessment devices.
[0003] A search revealed Chinese patent CN216013536U, which discloses a smart grid power quality assessment device. The device includes a base, a power assessment instrument housing mounted on top of the base, a control panel connected to one end of the housing, and a display screen mounted on one end of the control panel. A protective shell is movably mounted on one end of the display screen, with a guide groove at the connection between the protective shell and the control panel, and elastic pads on both sides of the guide groove. A buffer silicone pad is connected to the inner side of the protective shell. Compared to existing devices, this smart grid power quality assessment device uses a protective shell to surround the control panel for protection. The buffer silicone pad absorbs vibration when the protective shell is impacted, thus achieving a cushioning and shock absorption effect. This prevents the control panel of the smart grid power quality assessment device from being directly exposed to the outside environment, making it susceptible to impacts and friction, which could affect the device's lifespan.
[0004] The aforementioned smart grid power quality assessment device has the following shortcomings: the operation steps are relatively complicated, and the height of the power assessment instrument and the position of the protective shell need to be adjusted separately before it can be used. This requires a certain amount of time and effort, which prolongs the entire quality assessment process, affects the overall work efficiency, and has low practicality. Therefore, it is necessary to design a smart grid power quality assessment device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smart grid power quality assessment device.

The top of the two sleeve plates on the same side is fixedly connected to the same second handle.
[0013] Preferably, the bottom of the second handle is fixedly connected to two second guide rods, the second guide rods pass through the horizontal plate, the horizontal plate is slidably connected to the second guide rods, and the second guide rods are sleeved with second springs.
[0014] The beneficial effects of this utility model are as follows:
[0015] By employing a technique that allows the two protective shells to move away from each other during the rising process of the power quality assessor, thus exposing the display screen of the power quality assessor, the two protective shells move away from each other as the power quality assessor rises and move closer together until they make contact as the power quality assessor descends. This effectively protects the display screen of the power quality assessor and prevents damage to the power quality assessor due to collisions. This effectively solves the problems raised in the background technology, such as complex operation steps, the need to adjust the height of the power quality assessor and the position of the protective shells separately before use, the time and effort required, the prolongation of the entire quality assessment process, the impact on overall work efficiency, and low practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6A smart grid power quality assessment device includes a power quality assessment instrument body 1. Two protective shells 2 are provided at the display screen of the power quality assessment instrument body 1. Two fixing brackets 3 are provided on the side of the protective shell 2 away from the power quality assessment instrument body 1. A guide plate 4 is fixedly connected to the top of each fixing bracket 3. Two first sliding rods 5 are fixedly connected to the side of the protective shell 2 closest to the fixing brackets 3. The first sliding rods 5 are located on the top of the guide plate 4. A square groove 6 is opened at the top of the power quality assessment instrument body 1. Two first guide rods 7 are provided in the square groove 6. The first guide rods 7 are fixedly connected to the power quality assessment instrument body 1. The same fixing plate 8 is fixedly connected to the two first guide rods 7 on their adjacent sides. First springs 9 are provided on both sides of the fixing plate 8. The first springs 9 are sleeved on the first guide rods 7. A sliding plate 10 is sleeved on the first guide rods 7. The sliding plate 10 is slidably connected to the first guide rods 7. The top of the sliding plate 10 is fixedly connected to the protective shell 2. This invention employs a technique that allows the two protective shells to move away from each other during the rising process of the power quality assessor, exposing the display screen of the power quality assessor. As the power quality assessor rises, the two protective shells move away from each other; as the power quality assessor descends, the two protective shells move closer together until they make contact. This protects the display screen from damage caused by collisions. It effectively solves the problems raised in the background technology, such as complex operation steps requiring separate adjustments to the height of the power quality assessor and the position of the protective shells, which consumes time and effort, prolongs the entire quality assessment process, affects overall work efficiency, and has low practicality. This invention simplifies the operation steps, effectively streamlines the process, reduces adjustment time, and makes quality assessment work faster, effectively improving overall work efficiency and practicality.
[0025] In this utility model, the bottom of the power quality assessment instrument body 1 is provided with a base 11, and the top of the base 11 is fixedly connected to the bottom of the fixing frame 3.
[0026] In this utility model, a first handle 12 is fixedly connected to the top of the power quality assessment instrument body 1, and the device is carried by holding the first handle 12.
[0027] In this utility model, two support plates 13 are provided on both sides of the power quality assessment instrument body 1. Several first slots 14 are opened on the support plates 13. A sleeve plate 15 is fitted on the support plates 13. When the height of the power quality assessment instrument body 1 is adjusted, the power quality assessment instrument body 1 will drive the sleeve plate 15 to move along the support plates 13 to ensure the stability of the power quality assessment instrument body 1 when it moves. The sleeve plate 15 is fixedly connected to the power quality assessment instrument body 1.
[0028] In this utility model, a second slot 16 is provided on the sleeve plate 15. The second slot 16 is adapted to the first slot 14. An insert plate 17 is provided in the second slot 16. When the insert plate 17 is inserted into the first slot 14, the position of the sleeve plate 15 can be limited to ensure the stability of the position of the sleeve plate 15, which in turn can stabilize the height of the power quality assessment instrument body 1. One end of the insert plate 17 has two inclined surfaces.
[0029] In this utility model, two square plates 18 are fixedly connected to one side of the insert plate 17. The square plates 18 are provided with inclined sliding grooves 19. A second sliding rod 20 is provided in the inclined sliding grooves 19. The second sliding rod 20 is slidably connected to the square plates 18. When the second sliding rod 20 rises, it can squeeze the square plates 18 to move them. The square plates 18 will then drive the insert plate 17 to move out of the first slot 14, thereby adjusting the height of the sleeve plate 15, which in turn can adjust the height of the power quality assessment instrument body 1. The two second sliding rods 20 at the same end are fixedly connected to the same vertical plate 21. The tops of the two vertical plates 21 on the same side are fixedly connected to the same horizontal plate 22. The tops of the two sleeve plates 15 on the same side are fixedly connected to the same second handle 23.
[0030] In this utility model, the bottom of the second handle 23 is fixedly connected to two second guide rods 24. The second guide rods 24 pass through the horizontal plate 22, and the horizontal plate 22 is slidably connected to the second guide rods 24. The second guide rods 24 are fitted with second springs 25.
[0031] Working principle: In use, move the device to the position where evaluation and testing are required. The operator pulls the horizontal plate 22 with both hands, causing it to rise along the second guide rod 24. At the same time, the horizontal plate 22 compresses the second spring 25, causing it to contract. The rise of the horizontal plate 22 drives the vertical plate 21 to rise, which in turn drives the second sliding rod 20 to rise. The second sliding rod 20 then compresses the square plate 18, causing it to move. The square plate 18 then moves the insert plate 17 within the second slot 16, allowing the two insert plates 17 on the same side to come into contact with each other. By moving the insert plate 17 out of the first slot 14, the restriction on the sleeve plate 15 can be released, allowing the second handle 23 to rise. The second handle 23 will then lift the sleeve plate 15, which in turn will lift the power quality assessment instrument body 1. This allows the height of the power quality assessment instrument body 1 to be adjusted to adapt to different terrains. As the power quality assessment instrument body 1 rises, it will also lift the first guide rod 7 and the fixing plate 8, which will lift the sliding plate 10 and thus the protective shell 2. During the lifting of the protective shell 2, the first spring 9 will gradually extend. This allows the two sliding plates 10 to move away from each other, and thus the two protective shells 2 to move away from each other as well. Once removed from the display screen of the power quality assessor body 1, the power quality assessment can begin. Upon completion of the assessment, the horizontal plate 22 is raised again to remove the insert plate 17 from the first slot 14, causing the power quality assessor body 1 to descend until it contacts the base 11. During this process, the first sliding rod 5 contacts the guide plate 4. If the first sliding rod 5 continues to descend, the two first sliding rods 5 will move closer together, thus bringing the two protective shells 2 closer together. Until it closes, the sliding plate 10 will move closer to the fixed plate 8, and the sliding plate 10 will squeeze the first spring 9 to contract. When the bottom of the power quality assessor body 1 contacts the base 11, the horizontal plate 22 will be released, and the contracted second spring 25 will extend, which will allow the horizontal plate 22 to descend, and the second sliding rod 20 to descend. The second sliding rod 20 will then squeeze the square plate 18 again, which will cause the two insert plates 17 to move away from each other and be inserted back into the first slot 14 for limiting. After the insert plates 17 are inserted into the first slot 14, the storage work is completed.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
