The ring main unit comprises a gas tank, a cabinet body and an instrument chamber. The gas box is placed on the cabinet body, the instrument chamber is placed on the top of the cabinet body and is arranged in an upper-middle-lower mode in the whole space, a front plate in the gas box is provided with a five-station switch body integrating an isolating switch and a circuit breaker, a top plate in the gas box is fixedly provided with a supporting insulator, one end of the supporting insulator is fixedly connected with a main busbar, and the main busbar is provided with a static knife. One side plate of the gas box is fixedly provided with a side expansion sleeve with an umbrella skirt, one end of one end of the main busbar is connected with one end of the side expansion sleeve with the umbrella skirt, and the bottom of the gas box is provided with a pressure release valve. And reasonable layout is realized in a limited space, modular assembly is realized, and the insulation safety of main elements in the gas tank is ensured.

The utility model discloses a PP pipe fitting connecting device relates to pipe fitting connection technical field, including fixed pipe, connector and No.1 fixer, fixed pipe both ends are equipped with the connector, the inner wall of connector is equipped with spacing ring, the inner wall of connector is equipped with a plurality of guide wheel, and the fixed pipe is equipped with the fixed pipe. A plurality of bolts are installed on the outer wall of the connector in a penetrating mode, the bolts, the guide wheels and the insertion rods are connected through cables, and a first fixator is installed on the outer wall of the fixing pipe. Connection can be conveniently carried out by installing the connector, when connection is carried out, one end of a pipeline is inserted into the connector, at the moment, the supporting spring and the tough plate deform and are attached to the outer wall of the pipeline, the pipeline is preliminarily sealed, then the pipeline enters the limiting position, at the moment, the bolt is rotated, the bolt rotates to drive the cable to contract, and then the pipeline is sealed. And one end of the insertion rod is sharp, and the insertion rod is used for fixing the pipeline, so that a fixing function is realized.

The utility model discloses slope measuring equipment for land engineering, which comprises a measuring hand-push frame, a measuring box is mounted on one side of the measuring hand-push frame, a connecting rod is inserted into the bottom layer of the measuring box, a contact pitchdown body is mounted at the bottom of the connecting rod, a telescopic spring is mounted in the measuring box, and a connecting rod is mounted in the telescopic spring. The top end of the connecting rod is provided with a contact pen, and the rear end of the measuring box is in contact with a measuring touch screen. According to the utility model, through the arrangement of the mobile measurement structure, the mobile wheels at the bottom end of the hand-push frame are measured to move during use, the contact pituitary body at the bottom of the connecting rod inserted into the measurement box is driven to be connected with the ground, and the connecting rod is driven to rise in the measurement box after the contact pituitary body is contacted with the gradient on a road surface with a gradient; the contact pen at the top end of the measuring box is driven by the connecting rod to make contact with the measuring touch screen to move upwards so as to measure the numerical value of the moving angle, the numerical value on the measuring touch screen is transmitted to the information module through the wire, and therefore the moving measuring function is achieved.

The invention discloses an elevator car roof fixing structure, and relates to the technical field of elevator equipment, the elevator car roof fixing structure comprises a car, a car roof and a guide assembly, the car comprises a car body and a mounting frame, a plurality of uniformly distributed moving grooves are formed in the inner end of the mounting frame, and matched fixing assemblies are slidably mounted in the moving grooves; four evenly-distributed outer filling bags are fixedly connected to the outer end of the car roof, a plurality of evenly-distributed fixing grooves are further formed in the outer side wall of the car roof, electromagnets are installed in the fixing grooves, matched push plates are slidably installed at openings of the fixing grooves, and elastic liquid bags are fixedly connected between the push plates and the electromagnets. An internal pipeline is communicated between the elastic liquid bag and the outer filling bag, automatic fixing of the car roof is achieved through the adsorption effect of the electromagnet on the magnet block, in the installation process, fixing can be completed only by placing the car roof on the guide assembly and starting the electromagnet, manual accurate alignment and tightening operation are not needed, the installation process is greatly simplified, and the installation efficiency is improved. And the installation efficiency is improved.
