The invention discloses a starting mechanism of a mechanical time-telling watch. According to the starting mechanism, a through groove is formed on a spacer ring, and a pull core support is fixed in the through groove of the spacer ring; a connecting sleeve is respectively connected and fixed with one end of a pull core and a square end of a shifting hander as a whole, and the other end of the pull core is a free end; the pull core which is sheathed with a waterproof sealing pipe and a pressure spring penetrates through a connecting block and the pull core support; the pressure spring is arranged in a range of the length of the support; the connecting block is fixedly arranged at a gap formed on the pull core; the pull core penetrates through the connecting block, and the connecting block is fixedly connected with a shafting block; the shafting block in contact with or separated from a movement time-telling starting plate; and upper and lower ends of the exterior of the spacer ring are provided with waterproof rubber rings. The starting mechanism of the invention is advantageous in that: because waterproof rubber rings for sealing are arranged between the spacer ring and a watchcase, and a waterproof sealing pipe is arranged between the spacer ring and the inner pull core, the contact between the exterior and the interior is obstructed from an outermost end, and sealing is carried out from the interior, thereby enabling favorable dustproof and waterproof effects to be achieved. According to the starting mechanism, a sealing box is omitted, which enables a watch with a standard size to be small and thin.

The invention discloses a roll crusher, relates to the field of building material crushing, and aims at solving the problem that the crushing efficiency is influenced because a roll is liable to be damaged during material crushing of a crusher. The essential of the technical scheme is as follows: the roll crusher comprises at least two rolls which are synchronously and reversely driven, wherein crushing teeth are formed on the surrounding surface of each roll, and pits matched with the crushing teeth are formed in the roll which is matched with the previous roll; and the crushing teeth are detachably and fixedly connected to each roll. According to the roll crusher, the crushing teeth on the surface of each roll are configured to be detachable, so that replacement is facilitated, and thenthe crushing efficiency is increased.

The invention provides a vehicle height limiting system. It includes a front height limit reminder device and a rear height limit rack. The front height limit reminder device is composed of a height limit infrared measurement module, an LED screen, a cross bar, and a column. The rear height limit frame is composed of a pole and a height limit rope net. At present, most highway height-limiting poles use keel-type height-limiting racks. Although they are strong, they are prone to hard damage when they collide, causing damage to vehicles and the height-limiting racks themselves, and even accidents that cause personal casualties. However, this height limit system can remind super-high drivers to stop in time. When the driver does not process through the front height limit reminder device, the rear height limit pole can stop the vehicle in time, and its traffic limit device is a height limit net, so it can reduce Property damage due to hard collision.

The invention discloses a processing method of a bundle pipe type light-duty optical cable. First of all, two copper wires and multiple annular reinforced ribs spaced at equal intervals are symmetrically arranged along the axis of a PE sheath in the PE sheath, the multiple annular reinforced ribs are sleeved on the two copper wires along the radial direction of the PE sheath, a tubular-like a support frame is formed in the PE sheath, a center sleeve is fixed at the central portion of the PE sheath, after multiple fibers are arranged in the center sleeve, then the center sleeve is filled up with a fiber paste, the inner wall of the PE sheath is enabled to be fully supported, and thus processing of the optical cable is completed. When the optical cable encounters a corner or an area section with quite large bending amplitude, the PE sheath is deformed and distorted, at the moment, portions disposed inside the PE sheath extrude one another, the tubular frame formed by the copper wires and the reinforced ribs inside the PE sheath is correspondingly deformed in response to borne distortion stress so as to buffer the stress effect transmitted by the PE sheath to the sleeve and reduce the probability that the PE sheath is severely deformed and damaged.

The invention discloses a mixing device for desulfurization of flue gas generated by thermal power generation. The mixing device comprises a tank body, a motor and a fixing cylinder, wherein the motor is arranged on the fixing cylinder; a driving wheel is mounted on the extension section of the output end of the motor; the outer circumferential wall of a linking shaft is sleeved by a sleeve; one end of the sleeve penetrates through a flange disc and extends outwards; secondary blades are fixed on the outer circumferential wall of the extension section of the sleeve; the other end of the sleeve is arranged inside the fixing cylinder; a linking column is connected with one end of the sleeve; a cavity is formed inside the linking column; an inner tooth belt is arranged on the inner circumferential wall of the cavity; a gear is arranged on the linking shaft; one end of the linking shaft sequentially penetrates through the cavity and the rear wall of the tank body and extends continuously; a driven wheel is mounted on the extension section of the linking shaft; and main blades are mounted at the tail end of the linking shaft. Aiming at the problem that a conventional stirring blade is seriously damaged, the inventor designs a slurry stirring and mixing procedure which is applicable to relatively large solid-phase granules, namely, on premise that stable operation of stirring blades is ensured, the slurry stirring efficiency is improved.

The invention discloses an electromagnetic flowmeter scale cleaning device capable of improving precision. The electromagnetic flowmeter scale cleaning device comprises a flowmeter pipeline, mounting blocks are symmetrically and fixedly mounted on the inner wall of the top and the inner wall of the bottom of the flowmeter pipeline, and a set of paired measuring electrodes are mounted at the left ends of the two mounting blocks in an embedded mode; cleaning mechanisms are arranged in the two mounting blocks, cleaning fluid is led into the flowmeter pipeline by powering off, so that the cleaning fluid drives a cleaning wheel to be close to the bottom surface of the measuring electrode through the cleaning block, and dirt on the bottom surface of the measuring electrode is scraped by a mud scraping convex block with a frosted coating through rotation of the cleaning wheel, part of scraped dirt can be taken away in cooperation with introduced cleaning fluid, due to the fact that the flux of the cleaning fluid changes in real time, the cleaning block can drive the cleaning wheel to rub the measuring electrode left and right back and forth, cleaning work is completed, and hard damage to the measuring electrode can be reduced by arranging the mud scraping protruding block to be made of sponge materials.
