Description

Technical Field

[0001] This utility model relates to the field of power fault detection technology, specifically a DC grounding precise location device. Background Technology

[0002] In power systems, the safe and stable operation of DC systems is of paramount importance. DC grounding faults are one of the most common faults in DC systems. If they cannot be located and handled in a timely and accurate manner, they may cause serious safety accidents and affect the normal operation of the power system. DC system grounding fault locators are commonly used instruments for locating DC grounding faults. They are usually composed of a signal generator and a signal receiver. The signal generator is used to inject a specific signal into the DC system, and the signal receiver is used to receive the returned signal in order to locate the grounding fault.

[0003] However, in actual use, existing DC system ground fault locators usually require operators to hold the signal generator and signal receiver by hand. Since the two components lack effective protective structures in their design, if the instrument is dropped due to slipping or mistake during use, it is easy to collide directly with the ground and cause damage, affecting normal use and causing certain losses to users. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] The components of this application, including the signal generator 1, signal receiver 2, protective shell 3, connecting rope 4, elastic wristband 5, mounting baffle 6, connecting wire 7, clamp ammeter 8, slot 9, heat dissipation hole 10, receiving opening 11, locking hole 12, anti-slip texture 13, silicone raised strip 14, hollow rubber pad 15, hollow rubber strip 16, receiving groove 17, elastic locking plate 18, and hollow silicone block 19, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides a DC grounding precision positioning device, including a signal generator 1 and a signal receiver 2. A protective shell 3 is provided below the signal generator 1 and below the signal receiver 2. Hollow rubber pads 15 are fixedly connected to both ends of the bottom of the inner cavity of the protective shell 3. Silicone convex strips 14 are fixedly connected to all four sides of the outer surface of the protective shell 3. Slots 9 are provided at both ends of the top of the protective shell 3. Card holes 12 are provided at both ends of both sides of the outer surface of the protective shell 3, and the card holes 12 are in communication with the slots 9. Mounting baffles 6 are provided at both ends of the top of the signal generator 1 and the top of the signal receiver 2. Hollow silicone blocks 19 are fixedly connected to the top of the mounting baffles 6. Hollow rubber strips 16 are fixedly connected to the upper end of the mounting baffles 6. Receiving grooves 17 are provided at both ends of the mounting baffles 6. Elastic clamping plates 18 are fixedly connected to the top of the receiving grooves 17.

[0023] In this technical solution, when assembling the whole unit, the signal generator 1 and signal receiver 2 are first placed inside the protective housing 3, ensuring that the surfaces of the signal generator 1 and signal receiver 2 can contact the hollow rubber pad 15. Then, the mounting baffle 6 is inserted into the slot 9 on the protective housing 3. By pushing down the mounting baffle 6, the hollow rubber strip 16 is moved, allowing it to contact the surfaces of the signal generator 1 and signal receiver 2. Simultaneously, under the elastic force of the elastic locking plate 18, the lower protrusion can be engaged into the locking hole 12, thereby limiting the distance between the mounting baffle 6 and the protective housing 3 and preventing them from becoming loose. At the same time, under the action of the mounting baffle 6, the signal generator 1 and signal receiver 2 can be positioned... The upper part of the device 2 is limited to prevent the signal generator 1 and the signal receiver 2 from coming loose from the inside of the protective shell 3 during use. At the same time, the protective shell 3 can effectively protect the signal generator 1 and the signal receiver 2 from all sides, reducing the probability of damage to the signal generator 1 and the signal receiver 2 due to direct collision with objects. At the same time, the hollow rubber pad 15, hollow rubber strip 16, silicone protrusion 14 and hollow silicone block 19 can form a good collision buffer protection inside and outside the protective shell 3 and the mounting baffle 6, effectively reducing the impact on the signal generator 1 and the signal receiver 2 during the collision, further improving the overall protection effect, reducing the probability of damage caused by falling, and facilitating personnel use.

[0024] It should be noted that both signal generator 1 and signal receiver 2 are existing technologies and are components of a DC system ground fault locator. Signal generator 1 is used to inject a specific signal into the DC system, and signal receiver 2 is used to receive the returned signal in order to locate the ground fault.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a connecting wire 7 is fixedly installed on the back of the signal generator 1, and an alligator clip is fixedly installed on the surface of the connecting wire 7. A clamp meter 8 is fixedly installed on the back of the signal receiver 2. A connecting rope 4 is sleeved on the front surface of the protective shell 3. An elastic wristband 5 is fixedly connected to the left end of the connecting rope 4. An accommodating opening 11 is provided on the back of the protective shell 3. A heat dissipation hole 10 is provided on the bottom of the protective shell 3. Anti-slip textures 13 are provided on both sides of the outer surface of the protective shell 3. The mounting baffle 6 and the hollow rubber pad 15 are both L-shaped.

[0027] In this technical solution, by setting up the connecting rope 4 and the elastic wristband 5, when the personnel hold and use the signal generator 1 or the signal receiver 2, the elastic wristband 5 can be put on the wrist, thereby reducing the probability of collision with the ground due to falling. By setting up the receiving opening 11, the connection interface on the back of the signal generator 1 and the signal receiver 2 can be accommodated at the rear of the protective shell 3. By setting up the heat dissipation hole 10, since the position of the heat dissipation hole 10 is adapted to the heat dissipation port position of the signal generator 1 and the signal receiver 2, the heat of the signal generator 1 and the signal receiver 2 during operation can be dissipated to the outside. By setting up the anti-slip texture 13, the anti-slip effect between the hand and the protective shell 3 when the personnel hold it is effectively improved.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
