The invention relates to a system and a method for automatic in-situ monitoring on leakage of an underground sewage pipeline. The system provided by the invention comprises an upper computer for controlling and a resistivity feeler lever the bottom of which is provided with a cone head, the resistivity feeler lever is formed by splicing at least 5 pluggable nylon modules and copper pole rings which are clamped in the butt seam of two adjacent nylon modules, sliver is plated on the inner and outer surfaces of the copper pole rings, and the top of the resistivity feeler lever is provided with acollection control circuit and a wireless data transfer module; the collection control circuit comprises a control program and is connected with the copper pole rings by virtue of wires; a public network server and client software are matched with the wireless data transfer module. The monitoring method comprises the following steps: burying or penetrating a monitoring point positioned on the underground sewage pipeline into the resistivity feeler lever; and controlling the system to operate and automatically alarm when the leakage reaches the threshold by virtue of client software. The system and method provided by the invention integrates the functions of automatic collection, remote transmission, data storage, intelligent processing, automatic alarm and remote control, is simple to useand high in automaticity, and can be used for overcoming the defect on the real-time performance and accuracy of traditional methods.

The alarm speaker for the vehicle comprises a speaker body, a cover plate and an inner casing provided with an accommodating cavity, wherein the speaker body is located in the accommodating cavity of the inner casing; the cover plate and the inner casing are fixed to axially limit the speaker body; at least one boss is arranged on the outer circumferential surface of the inner casing; at least one bulge is further arranged on the outer circumferential surface of the inner casing; a wire used for being connected with a circuit board is arranged on the speaker body, and one end of the wire penetrates through the inner casing from inside to outside. The alarm speaker for the vehicle has the characteristic of wide mounting position range.

The invention provides a guardrail steel cable quick locking device which is used for being installed on the portion, close to the end of a steel cable, of the steel cable and detachably fixed to a guardrail. The locking device comprises an outer sleeve, a conical chuck, an elastic component and an installing and fixing mechanism, wherein the outer sleeve is provided with a conical through hole and a first internal thread hole which are communicated with each other, and the hole diameter of the first internal thread hole is larger than or equal to the largest hole diameter of the conical through hole. The conical chuck is provided with a clamping hole used for the steel cable to pass, a plurality of clamping teeth are arranged in the clamping hole, and the conical chuck is placed in the conical through hole of the outer sleeve. The elastic component is placed at the bottom of the conical chuck in the outer sleeve. The installing and fixing mechanism is fixedly installed on the guardrail and provided with a first external threaded rod, the first external threaded rod is combined with the first internal thread hole in a screwed mode, and the elastic component is placed at the end of the first external threaded rod. The guardrail steel cable quick locking device can be installed upwards and downwards by 0-90 degrees, and the steel cable can freely rotate by 360 degrees. The guardrail steel cable quick locking device is enough in locking force, not prone to loosening after bearing external force, wide in applicability, convenient to install and high in work efficiency.
