Description

Technical Field

[0001] This application relates to the field of leakage current detection technology, specifically to a leakage current detection device for engineering supervision. Background Technology

[0002] To ensure electrical safety at construction sites and prevent electric shock and electrical fire accidents, leakage current testing is required during project supervision. This ensures the effective and reliable operation of the leakage current protection system at the construction site. Common devices for detecting leakage current include leakage current testers and clamp meters.

[0003] The existing Chinese patent document CN208334530U discloses that, in order to ensure that the first induction coil and the second induction coil can form a closed induction circuit, a first engaging member and a second engaging member can be respectively set at the second end of the first clamp body and the second clamp body. The first engaging member is a groove and the second engaging member is a protrusion. This setting can ensure that the second end of the first clamp body and the second clamp body can be engaged more smoothly, improving the convenience of operation. For the clamp meter to detect accurately, it is necessary to ensure that the jaws are tightly closed and clean. If there is dirt or impurities in the jaws after the clamp meter has been used for a long time, it will cause changes in the magnetic field. When cleaning the jaws of the existing clamp meter, it may be necessary for the staff to wipe the jaws separately, which leads to low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a leakage current detection device for engineering supervision, so as to solve the technical problem of low efficiency caused by workers wiping the jaws of the clamps separately.

[0005] The technical solution of this utility model is as follows: An engineering supervision leakage current detection device includes a detection unit and a cleaning unit. The detection unit includes a first jaw and a second jaw that can be opened and closed relative to each other in the left and right directions. A groove is provided on the right side of the first jaw, and a protrusion for fitting the groove is provided on the left side of the second jaw. The cleaning unit includes a handheld component, which includes a left handheld arm and a right handheld arm that can be opened and closed relative to each other in the left and right directions. The left handheld arm and the right handheld arm include a rigid segment connected at the bottom. A left elastic base plate is connected to the end of the rigid segment of the left handheld arm. A left flexible friction member for fitting the groove is fixed to the left side of the left elastic base plate.

A right flexible friction member for fitting the protrusion is fixed to the left side of the right elastic base plate.

[0006] The beneficial effects of this technical solution are as follows: When using an engineering supervision leakage current detection device, the first and second jaws open via a handheld component to clean the grooves and protrusions.

Moving the handheld component moves the left and right flexible friction components, which then remove dust or impurities from the grooves and protrusions. The left and right elastic substrates allow the left and right flexible friction components to adapt to the grooves and protrusions, ensuring a tight fit and thorough cleaning. The simultaneous cleaning operation by the left and right flexible friction components solves the problem of inefficiency caused by workers wiping the jaws separately.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0016] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0017] A specific embodiment of the leakage current detection device for engineering supervision of this utility model is as follows: Figure 1-3As shown, the device includes a detection unit and a cleaning unit. The detection unit includes a first jaw 1 and a second jaw 2 that can open and close relative to each other in the left-right direction. A groove 101 is provided on the right side of the first jaw 1, and a protrusion 201 for fitting the groove 101 is provided on the left side of the second jaw 2. The cleaning unit includes a handheld component 3, which includes a left handheld arm 301 and a right handheld arm 302 that can open and close relative to each other in the left-right direction. The left handheld arm 301 and the right handheld arm 302 include rigid sections connected at their bottoms. The end of the rigid section of the left handheld arm 301 is connected to a left elastic substrate 303. A left flexible friction member 304 for fitting the groove 101 is fixed to the left side of the left elastic base plate 303. The rigid end of the right hand arm 302 is connected to the right elastic base plate 305. A right flexible friction member 306 for fitting the protrusion 201 is fixed to the left side of the right elastic base plate 305. The left flexible friction member 304 and the right flexible friction member 306 are made of rubber. The rubber material ensures that the surface of the groove 101 and the protrusion 201 will not be damaged when cleaning.

[0018] The beneficial effects of this technical solution are as follows: When using an engineering supervision leakage current detection device, the handheld component 3 opens the first jaw 1 and the second jaw 2 when cleaning the groove 101 and the protrusion 201 is required. Then, the left flexible friction component 304 and the right flexible friction component 306 are placed inside the groove 101 and the protrusion 201. Moving the handheld component 3 causes the left flexible friction component 304 and the right flexible friction component 306 to move, thereby cleaning the groove 101 and the protrusion 201. 01. The removal of dust or impurities inside is achieved through the left elastic substrate 303 and the right elastic substrate 305, which allow the left flexible friction element 304 and the right flexible friction element 306 to adapt to the groove 101 and the protrusion 201. This ensures that the left flexible friction element 304 and the right flexible friction element 306 are in close contact with the groove 101 and the protrusion 201, guaranteeing thorough cleaning. The simultaneous cleaning operation by the left flexible friction element 304 and the right flexible friction element 306 solves the problem of low efficiency caused by workers wiping the jaws separately.

[0019] The left hand arm 301 and the right hand arm 302 are integrated into one unit.

[0020] The bottom of the left hand arm 301 and the right hand arm 302 are hinged together, and a spring 4 connects the left hand arm 301 and the right hand arm 302.

[0021] The left hand-held arm 301 and the right hand-held arm 302 are provided with a gap hole along the length direction, and the gap hole is connected to the spring 4 by a hook.

[0022] The beneficial effects of this technical solution are as follows: After a period of use, the spring 4 may become fatigued due to the multiple interval holes, which may reduce its elasticity. The interval holes allow the spring 4 to be moved downwards, thus enabling the spring 4 to maintain its elasticity.

[0023] The thickness of the left elastic substrate 303 is half the thickness of the left hand arm 301.

[0024] The left elastic substrate 303 allows the left flexible friction element 304 to adapt to the groove 101, thereby ensuring that the left flexible friction element 304 and the groove 101 fit tightly together and that cleaning is thorough.

[0025] The right elastic substrate 305 is adapted to the protrusion 201.

[0026] The right-side elastic substrate 305 enables the right-side flexible friction element 306 to adapt to the protrusion 201, thereby ensuring that the right-side flexible friction element 306 and the protrusion 201 fit tightly together and that cleaning is thorough.

[0027] In use, the first jaw 1 and the second jaw 2 are opened, and then the left flexible friction element 304 and the right flexible friction element 306 are placed inside the groove 101 and the protrusion 201. The handheld part 3 is moved, and the movement of the handheld part 3 causes the left flexible friction element 304 and the right flexible friction element 306 to move, thereby removing the dust or impurities inside the groove 101 and the protrusion 201, and completing the cleaning operation.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
