Description

Technical Field

[0001] The invention belongs to the technical field of clamp ammeters, and in particular relates to a wireless high and low voltage clamp ammeter carried by an unmanned aerial vehicle. Background Art

[0002] A clamp ammeter, also known as a clamp meter, is an instrument used to measure the current in a running electrical circuit. When measuring current, the circuit being measured usually needs to be disconnected so that the primary side of the ammeter or transformer can be connected in series to the circuit; when using a clamp ammeter to measure current, it can be done without disconnecting the circuit. It is also widely used in the field of drones. The clamp ammeter is small in size and can be easily carried by drones.

[0003] The existing wireless high and low voltage clamp ammeter needs to open the clamp body through the clamp switch during installation in order to install and subsequently detect the wires. However, when there are a large number of wires to be installed and there are missed wires, once the clamp body is opened, the wires originally to be tested will be moved out again, which is inconvenient to operate. Therefore, there are great limitations in use and there is room for improvement. Summary of the invention

[0004] The purpose of the present invention is to provide a wireless high and low voltage clamp ammeter carried by an unmanned aerial vehicle to solve the problem that the existing clamp ammeter proposed in the above background technology relies too much on the jaw switch to open the clamp body. Once this method cannot meet the needs of picking and releasing the wire, it will cause great inconvenience to use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wireless high and low voltage clamp ammeter carried by an unmanned aerial vehicle, comprising a body, a fixed clamp body and a limit clamp body are installed on the top of the body, and a display screen is installed on the surface; a jaw switch is rotatably connected to the side of the body, and the top of the jaw switch is connected to the bottom of the limit clamp body. In use, the limit clamp body is opened by pressing the jaw switch, so that the wires on the unmanned aerial vehicle are placed and detected; the top of the limit clamp body is rotatably connected to a movable clamp head, and an auxiliary component is arranged between the movable clamp head and the limit clamp body, and the auxiliary component comprises: a connecting piece, which is arranged on the opposite surface of the limit clamp body and the inner side of the movable clamp head; a detection piece, which is built into the inner bottom end surface of the movable clamp head; a handle is fixed on the outer side of the top of the movable clamp head, and the handle is arc-shaped. When it is necessary to temporarily place the wires in the fixed clamp body and the limit clamp body, the movable clamp head is opened by the handle, and then the wires are placed;

[0006] A suction cup is also installed on the rear surface of the body, and the suction cup is negatively adsorbed on the surface of the drone. At least one exhaust hole is opened on the side of the suction cup, and a baffle that can be pushed open by air pressure is arranged inside the exhaust hole. There are multiple baffles, and the end points of the multiple baffles coincide with the hole center of the exhaust hole. When the suction cup is connected to the drone, the gas inside the suction cup is discharged through the exhaust hole, which can improve the adsorption strength. A sleeve is also sleeved on the top of the suction cup, and a connecting rod is fixed at the top of the sleeve. An adhesive layer is installed on the bottom end of the connecting rod. During installation, the suction cup will gradually tend to a flush state, and at the same time, the whole will move toward the direction of the sleeve. At this time, the adhesive layer in the sleeve gradually approaches the bottom end surface of the suction cup, and when the suction cup is attached to the drone, it is simultaneously bonded to the drone to improve the installation stability; a stud is also fixed on the top of the sleeve, and the stud is threadedly connected to the drone. The height of the suction cup and the sleeve can be adjusted by the stud, and installation can be achieved according to different heights.

[0007] As a preferred technical solution in the present invention, a connecting groove is provided on the inner side surface of the bottom end of the movable clamp head, and a groove identical to the connecting groove is also provided on the inner side of the top of the limiting clamp body. Metal sleeves are placed in the groove and the connecting groove, and a magnetic plate is provided inside the metal sleeve. In normal use, magnetic attraction is achieved by the magnetic plates in the two metal sleeves to prevent the limiting clamp body from separating from the movable clamp head. When the movable clamp head needs to be opened, the movable clamp head can be opened by applying a pulling force from the outside.

[0008] As a preferred technical solution in the present invention, double-sided tape is bonded to both sides of the metal sleeve, and the double-sided tape is bonded to the connecting groove and the side wall of the groove, so as to achieve installation.

[0009] As a preferred technical solution in the present invention, the total thickness of the metal sleeve and the double-sided tape is equal to the depth of the connecting groove and the side wall of the groove, ensuring that the metal sleeve will not protrude to the outside of the movable clamp head after installation, and the bottom end surfaces of the two metal sleeves are flush with the bottom end surface of the movable clamp head and the top end surface of the limiting clamp body, thereby achieving the purpose of planar magnetic connection.

[0010] As a preferred technical solution in the present invention, a slot is provided on the bottom end surface of the movable clamp head, and a distance sensor is installed in the slot. The transmitting end of the distance sensor is located directly above the limit clamp body. The distance sensor has a built-in wireless module and is connected to the display screen on the body to detect the distance between the limit clamp body and the movable clamp head, thereby avoiding the problem of excessive spacing between the limit clamp body and the movable clamp head when the movable clamp head does not need to be opened.

[0011] As a preferred technical solution in the present invention, a function disk is also installed on the front surface of the body, which is connected to the circuit board inside the body. Data is read and the measurement method is changed through the function disk. Since this structural principle is a prior art, it will not be further elaborated here.

[0012] As a preferred technical solution in the present invention, a card plate is further provided on the rear surface of the body, one end of the card plate is in contact with the body and forms a mounting portion, the mounting portion is provided with a screw hole, and a bolt for fixing the body is screwed into the screw hole to achieve the installation of the card plate; there is a distance between the other end of the card plate and the body, and a card slot is provided inside the other end of the card plate, and the support rod and bracket on the drone are clamped and limited by the card slot to achieve auxiliary installation of the body.

[0013] As a preferred technical solution in the present invention, the distance between the clamping plate and the body gradually increases from the opening toward the inside, and the clamping plate is made of plastic material for easy clamping.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the designed auxiliary components, the pliers body can be partially opened, and the operation mode can be changed according to the actual needs of taking out the discharge wire, avoiding over-reliance on the jaw switch and causing certain inconvenience to normal use. At the same time, the auxiliary component can form a complete individual with the pliers body when not in use, which not only ensures the beauty of the overall structure, but also will not affect normal use, and has high practicality and flexibility.
