Description

Technical Field

[0001] The utility model relates to the technical field of line loss detection mechanisms, in particular to a line loss detection mechanism for electric power engineering. Background Art

[0002] Line loss, also known as power grid energy loss, refers to the energy loss and losses incurred in the transmission, transformation, distribution and marketing links during the transmission of electricity from power plants to power users. Specifically, it refers to the active, reactive energy and voltage losses generated when current flows through various power equipment in the power grid within a certain period of time. It is usually referred to as active energy loss.

[0003] For example, the line loss detection device for electric power engineering with publication number CN218412759U includes: a box body, a fixing seat, a detector, a test clip, and a placement slot. The fixing seat is installed inside the box body, the detector is placed inside the fixing seat, and the test clip is placed inside the fixing seat close to the detector. In this line loss detection device for electric power engineering, the detector of the electric power engineering line loss detector will be held by the operator for operation when in use. When the operator makes a mistake and causes the detector to fall, the line loss detector will be damaged and cannot be used anymore. At this time, the detector can be protected all around. When the second connecting block is collided, the first spring can be squeezed and deformed by the squeezing. At this time, the engaging block can be engaged with the engaging slot by the elastic force of the second spring, so that the wires on the test clip can be squeezed and restricted by the fixing block when the electric power engineering line loss detector is in use, so that the wires will not be scattered and can be stored conveniently.

[0004] It can be seen from the above patent that when the line loss detection device is used, the operator manually clamps the test clip to the outside of the contact block of the tested line, and then performs the line loss detection operation through the detector. Since the voltage of some lines is relatively high, sparks may be generated as the clip contacts the line contact block, splashing onto the operator's hand and causing injury to the operator, which is very dangerous.

[0022] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The utility model provides a technical solution: Figure 1 - Figure 5 The utility model discloses a power engineering line loss detection mechanism, comprising an insulating cylinder 1 and a wire 2. An adsorption mechanism 3 is provided in the insulating cylinder 1. The adsorption mechanism 3 includes a push rod 31 with a T-shaped cross-section. The top end of the push rod 31 slides through the bottom wall of the insulating cylinder 1. The push rod 31 is provided with a power connection mechanism 4.

[0024] The power connection mechanism 4 includes a contact rod 42, a slide groove 41 is provided at the top of the push rod 31, and the contact rod 42 is slidably installed in the slide groove 41. A plurality of connection holes 43 are provided in a circular array on the outer peripheral wall of the top of the push rod 31. The top of the wire 2 is slidably inserted into the slide groove 41 from the center position of the bottom side of the push rod 31 and is electrically connected to the contact rod 42, and the outer skin of the wire 2 is fixedly connected to the contact rod 42.

[0025] In this embodiment, when the improved power engineering line loss detection mechanism is used, the operator first connects the connection end of the wire 2 to the detector, then holds the insulating cylinder 1 and presses the push rod 31, the adsorption mechanism 3 operates to push out the gas in the opening of the insulating cylinder 1, and then moves the insulating cylinder 1 to the electric shock block of the detection line. After the insulating cylinder 1 is in contact with the electric shock block, the operator releases the pressing state of the push rod 31. At this time, the adsorption mechanism 3 forms a negative pressure cavity in the opening of the insulating cylinder 1, and the insulating cylinder 1 is stably adsorbed and fixed on the electric shock block;

[0026] When a negative pressure cavity is formed in the opening of the insulating tube 1, part of the gas in the chute 41 will be sucked out from the connecting hole 43, thereby forming a negative pressure cavity in the chute 41 synchronously, pulling the electric shock rod 42 out of the chute 41, and then making the electric shock rod 42 automatically extend from the insulating tube 1 and fit tightly against the electric shock block of the external circuit, automatically completing the electrical connection between the detection circuit electric shock block and the detector. Due to the shielding of the insulating tube 1, even if sparks are generated when the electric shock rod 42 contacts the electric shock block, it will not splash onto the operator's hands, and the danger is relatively small when the device is connected to the detection circuit.

[0027] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the cross-sectional shape of the electric shock rod 42 and the cross-sectional shape of the chute 41 are both T-shaped, and the outer peripheral walls of the upper and lower ends of the electric shock rod 42 are in contact with the inner wall of the chute 41. A sealing ring 44 is fixedly installed in the rod wall at the bottom end of the electric shock rod 42, and the outer peripheral wall of the sealing ring 44 is in contact with the inner wall of the chute 41;

[0028] In this embodiment, the setting of the sealing ring 44 can enhance the sealing strength between the outer peripheral wall of the bottom end of the electric shock rod 42 and the inner wall of the slide groove 41. The shape of the cross section of the electric shock rod 42 and the shape of the cross section of the slide groove 41 are both T-shaped. The electric shock rod 42 can be constrained and limited by the interference between the electric shock rod 42 and the inner wall of the slide groove 41, so that the electric shock rod 42 will not slide out of the slide groove 41.

[0029] In a further preferred embodiment of the present invention, Figure 4 As shown, a first spring 45 is wound around the outer periphery of the electric shock rod 42, and both ends of the first spring 45 are fixedly connected to the electric shock rod 42 and the inner wall of the slide groove 41 respectively;

[0030] In this embodiment, after the negative pressure state in the opening of the insulating tube 1 is released, due to the push of the first spring 45 on the electric shock rod 42, the electric shock rod 42 that slides out of the slide groove 41 automatically retracts into the slide groove 41, and automatically pushes out the wire 2 that slides into the slide groove 41 to facilitate the subsequent use of the device.

[0031] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the adsorption mechanism 3 includes a piston plate 32, which is fixedly sleeved on the outer peripheral side of the top of the push rod 31, and the outer peripheral wall of the piston plate 32 contacts the inner wall of the insulating cylinder 1. A second spring 33 is provided between the top side of the piston plate 32 and the inner wall of the insulating cylinder 1, and the two ends of the second spring 33 are fixedly connected to the piston plate 32 and the inner wall of the insulating cylinder 1 respectively;

[0032] In this embodiment, when the push rod 31 is pushed into the insulating cylinder 1, the push rod 31 moving into the insulating cylinder 1 pushes the piston plate 32 toward the opening of the insulating cylinder 1, thereby pushing out the gas in the opening of the insulating cylinder 1;

[0033] After the insulating tube 1 is fitted with the electric shock block, the pressure of the push rod 31 is released. Due to the push of the piston plate 32 by the second spring 33, the piston plate 32 automatically slides in the direction away from the opening of the insulating tube 1, thereby expanding the area between the top side of the piston plate 32 and the inner wall of the opening of the insulating tube 1, and then forming a negative pressure cavity in the opening of the insulating tube 1, automatically adsorbing and fixing the insulating tube 1 on the electric shock block. The device is simple to operate and facilitates the connection between the insulating tube 1 and the detection circuit electric shock block.

[0034] In a further preferred embodiment of the present invention, Figure 2 As shown, a plurality of circular holes 36 are opened on the bottom side of the insulating cylinder 1, and the plurality of circular holes 36 are arranged in a circular array on the outer circumference of the push rod 31;

[0035] In this embodiment, as the piston plate 32 moves, the gas at the bottom of the insulating cylinder 1 can exchange gas with the outside through the circular hole 36, so that no high-pressure cavity or negative-pressure cavity is formed at the bottom of the insulating cylinder 1 to affect the movement of the piston plate 32.

[0036] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, an annular groove 34 is formed on the top side of the insulating cylinder 1, and a soft ring 35 is provided in the annular groove 34. The outer peripheral wall of the soft ring 35 contacts the inner wall of the annular groove 34. The interior of the soft ring 35 is hollow and filled with air. The top side of the soft ring 35 extends to the outside of the annular groove 34.

[0037] In this embodiment, after the insulating tube 1 and the shock block are fitted together, due to the pressure of the insulating tube 1 on the soft ring 35, the soft ring 35 adaptively deforms according to the contact position of the shock block, thereby blocking the gap between the insulating tube 1 and the shock block. The operator does not need to perform other operations, thereby facilitating the connection between the insulating tube 1 and the detection circuit shock block.

[0038] Working principle: When using the improved power engineering line loss detection mechanism, the operator first connects the connection end of the wire 2 to the detector, then holds the insulating cylinder 1 and presses the push rod 31. The push rod 31 moving into the insulating cylinder 1 pushes the piston plate 32 toward the opening of the insulating cylinder 1, thereby pushing out the gas in the opening of the insulating cylinder 1. Then, the insulating cylinder 1 is moved to the contact block of the detection line. After the insulating cylinder 1 and the contact block are attached, due to the pressure of the insulating cylinder 1 on the soft ring 35, the soft ring 35 adaptively deforms according to the contact position of the contact block, thereby blocking the gap between the insulating cylinder 1 and the contact block.

[0039] After the operator fits the insulating cylinder 1 onto the electric shock block, he releases the pressure of the push rod 31. Due to the push of the piston plate 32 by the second spring 33, the piston plate 32 automatically slides away from the opening of the insulating cylinder 1, thereby expanding the area between the top side of the piston plate 32 and the inner wall of the opening of the insulating cylinder 1, thereby forming a negative pressure chamber in the opening of the insulating cylinder 1, and automatically adsorbing and fixing the insulating cylinder 1 on the electric shock block;

[0040] It should be noted that as the piston plate 32 moves, the gas at the bottom of the insulating cylinder 1 can exchange gas with the outside through the circular hole 36, so that no high-pressure cavity or negative-pressure cavity is formed at the bottom of the insulating cylinder 1 to affect the movement of the piston plate 32;

[0041] When a negative pressure cavity is formed in the opening of the insulating tube 1, part of the gas in the chute 41 is sucked out through the connecting hole 43, thereby forming a negative pressure cavity in the chute 41, pulling the electric contact rod 42 out of the chute 41, and then the electric contact rod 42 automatically extends from the insulating tube 1 and comes into close contact with the electric contact block of the external circuit, automatically completing the electrical connection between the detection circuit electric contact block and the detector;

[0042] It should be noted that as the electric shock rod 42 slides out of the chute 41, the wire 2 is pulled into the chute 41 together, thereby avoiding the formation of a high-intensity negative pressure cavity between the bottom end of the electric shock rod 42 and the inner wall of the chute 41, which affects the sliding of the electric shock rod 42 out of the chute 41;

[0043] After the above-mentioned line loss detection of the power engineering of the line is completed, the operator presses the push rod 31 again according to the above-mentioned method to release the negative pressure state in the opening of the insulating tube 1. At this time, the operator can directly remove the insulating tube 1 from the electric shock block;

[0044] As the negative pressure state in the opening of the insulating tube 1 disappears, the first spring 45 pushes the electric shock rod 42, and the electric shock rod 42 that slides out of the slide groove 41 automatically retracts into the slide groove 41, and automatically pushes out the wire 2 that slides into the slide groove 41 to facilitate the subsequent use of the device.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
