Description

Technical Field

[0001] The utility model relates to the technical field of oil-water mixing transmitters, in particular to a drop-in oil-water mixing transmitter controller. Background Art

[0002] The oil-water mixing transmitter controller is a device used to detect the water content in the turbine oil. The lubricating oil in the generator set is 46# turbine oil. The oil-water mixing transmitter controller is needed to measure the water content in the oil. If the water content is greater than a certain value, the turbine oil must be replaced.

[0003] When using an oil-water mixing transmitter controller, a probe is inserted into the turbine oil. The data detected by the probe is transmitted via a wire to the signal amplifier chip within the controller. Current oil-water mixing transmitter controllers typically have a relatively short measuring range, meaning the wire is relatively short, rarely exceeding 1 meter. Testing has shown that if the wire exceeds 1 meter, the detection signal attenuates in the wire, resulting in inaccurate and unstable measurement data. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the utility model provides a drop-in oil-water mixing transmission controller.

[0005] The utility model is realized through the following technical solution, and provides a submersible oil-water mixing transmitter controller, comprising a transmitter head and a detector head, characterized in that: it also comprises a detector head housing, a mounting countersunk hole is provided at the front end of the detector head housing, an insulating gasket is fixedly connected to the bottom of the mounting countersunk hole, a rear end of the detector head is embedded in the insulating gasket, a receiving groove is provided at the bottom of the mounting countersunk hole, a signal amplifying chip is arranged in the receiving groove, a signal line at the rear end of the detector head is sealed and passes through the insulating gasket and is electrically connected to the signal amplifying chip, and the signal amplifying chip is electrically connected to the transmitter head through a cable that is sealed and passes through the rear end of the detector head housing.

[0006] As an optimization, a plurality of through holes are opened on the side of the mounting countersunk hole, so as to facilitate the turbine oil to enter the mounting countersunk hole and fully contact the detection head.

[0007] As an optimization, the insulating gasket is threadedly connected to the mounting countersunk hole, and the detection head is threadedly connected to the insulating gasket, thereby facilitating installation, and the threaded connection can also achieve a certain sealing effect.

[0008] As an optimization, the hole through which the cable passes through the housing of the detection head is sealed by a potted epoxy resin filling block, thereby preventing liquid from entering the receiving groove through the hole at the rear end.

[0009] As an optimization, it further includes a welding mounting frame and a mounting connecting plate fixed to the side of the detection head housing, wherein the mounting connecting plate is connected to the welding mounting frame by bolts, thereby realizing the installation of the detection head housing at the position to be detected.

[0010] As an optimization, the front end of the detection head is located in the mounting countersunk hole, thereby protecting the front end of the detection head.

[0011] As an optimization, the receiving groove is a circular countersunk hole with a diameter smaller than that of the mounting countersunk hole, thereby reducing the volume of the entire detection head housing.

[0012] The beneficial effects of the utility model are as follows: the utility model is a submersible oil-water mixing transmitter controller, which places the signal amplification chip and the detection head together in the detection head housing, and then connects to the transmitter head through a cable. In this way, even if the measuring range is very long and the line length exceeds 5 meters, the measurement is still very stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0018] like Figures 1 and 2 As shown, the present invention provides a submersible oil-water mixing transmitter controller, comprising a transmitter head 2, a detector head 8, and a signal amplifier chip 10. The detector head 8 is placed in the turbine oil to be tested. The detected signal is transmitted to the signal amplifier chip 10 and then transmitted via a cable 3 to the transmitter head 2. The transmitter head 2 is provided with a display screen for displaying the detected value. In this embodiment, the cable 3 can be up to 5 meters long.

[0019] Also includes a detection head housing 1, such as Figure 2 As shown, the exterior of the detection head housing 1 is cylindrical, and a mounting countersunk hole is opened at the front end of the detection head housing 1. The mounting countersunk hole is a circular countersunk hole, and its length is greater than the length of the detection head 8.

[0020] An insulating gasket 9 is fixed to the bottom of the mounting countersunk hole and is threadedly connected to the mounting countersunk hole, preventing liquid from passing between the insulating gasket 9 and the mounting countersunk hole. The rear end of the detection head 8 is embedded in the insulating gasket 9, and the detection head 8 is threadedly connected to the insulating gasket 9. After the detection head 8 is installed, the front end of the detection head 8 is located in the mounting countersunk hole, thereby protecting the front end of the detection head 8.

[0021] The side surface of the mounting countersunk hole is provided with a plurality of through holes 6 to facilitate the turbine oil to enter the mounting countersunk hole and fully contact the detection head 8.

[0022] The bottom of the mounting countersunk hole has a receiving groove, which is a circular countersunk hole with a smaller diameter than the mounting countersunk hole. A signal amplifier chip 10 is positioned within the receiving groove. The signal line at the rear end of the detection head 8 is sealed and passed through the insulating gasket 9 before being electrically connected to the signal amplifier chip 10. Because the connection between the detection head 8 and the insulating gasket 9 is sealed, and the connection between the insulating gasket 9 and the mounting countersunk hole is sealed, liquid cannot enter the receiving groove and, therefore, cannot come into contact with the signal amplifier chip 10.

[0023] The signal amplifier chip 10 is electrically connected to the transmitter head 2 via a sealed cable 3 that passes through the rear end of the detector housing 1. The hole through which the cable 3 exits the detector housing 1 is sealed by a potted epoxy resin filler 7. During processing, the hole is filled with epoxy glue, which solidifies to form the epoxy resin filler 7, providing a seal.

[0024] In order to achieve installation, a welding mounting frame 5 and a mounting connecting plate 4 fixed to the side of the detection head housing 1 are also included. The mounting connecting plate 4 is connected to the welding mounting frame 5 by bolts.

[0025] The use method of this utility model:

[0026] When in use, first assemble all the components, weld the welding mounting frame 5 to the position that needs to be detected, and then install and fix the detection head housing 1 by installing the connecting plate 4, so that the detection head 8 is in the turbine oil that needs to be detected, and the detection signal is transmitted to the signal amplification chip 10, and then transmitted to the transmitter head 2 through the cable 3, and the detection value is displayed on the display screen of the transmitter head 2.

[0027] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
