The purpose of the present invention is to easily carry out manual operations for operating tools when inclination attitude for front, back, left, and right of a traveling machine body is changed by a manual operation of a height operating tool or inclination operating tool. This traveling vehicle is provided with: a traveling machine body (1) supported by left and right traveling units (2); a rolling actuator (38) that changes the inclination attitude of the traveling machine body (1) in the left and right directions; and a pitching actuator (177) that changes the inclination attitude of the traveling machine body in the front and back directions. A vehicle height operating tool (57) that carries out operations changing the vehicle height for the traveling machine body (1) is provided on either of a steering operating tool (11) disposed in front of an operator seat (12) on the traveling vehicle body (1) or a steering column (46) that supports the steering operating tool (11), and an inclination operating tool (56) that carries out operations for changing the inclination attitude of the traveling machine body (1) is provided on the other.

The invention discloses energy-saving automatic water treatment equipment with a backwashing barrier. The energy-saving automatic water treatment equipment structurally comprises a water inlet, a barrier pool, a facultative tank, a pool, a sludge storage pool, partitioning plates, a box body and a controller, wherein the controller is arranged at the outer side of the box body; the inner part of the box body is partitioned into the barrier pool, the facultative tank, the pool and the sludge storage pool in sequence by the partitioning plates; the barrier pool is communicated with the water inlet; the vertical barrier plate is arranged at the middle part of the inside of the barrier pool; a brushing device is arranged at the left side of the barrier plate. The energy-saving automatic watertreatment equipment disclosed by the invention has the beneficial effects that the barrier plate is cleaned by matching of brushing and airflow recoil, so that the brushed dirt can be prevented from rushing towards one side for filtering; working does not need to be stopped in cleaning, so that the working efficiency is improved; a U-shaped pipeline can carry out reverse washing on the barrier plate by utilizing the own inertia of water flow, so that the probability of blockage of through holes of the barrier plate can be reduced, and the water passing volume can be increased; by the U-shapedpipeline, the cleaning times can be reduced, continuous working is not needed and the power consumption cost can be reduced.

The invention provides a flue-gas denitration pretreatment device for a power plant utilizing agriculture and forestry waste. The flue-gas denitration pretreatment device comprises a high-temperatureflue, wherein a rotary screen is mounted in the interior of the high-temperature flue; the rotary screen comprises a temperature-resistant rotating shaft, a temperature-resistant bearing bracket and barrel-shaped screen nets; the inner wall of the high-temperature flue is provided with a portal-shaped sealing frame made from a flexible graphite material; the front side and rear side of the rotaryscreen are provided with arc-shaped front striker plate and rear striker plate, wherein the widths of the front striker plate and rear striker plate are more than the space between two barrel-shaped screen nets, respectively; the lower wall surface of the high-temperature flue is provided with an ash bucket; the ash bucket is located below the rotary screen; an outlet of the ash bucket is providedwith a twin-stage heavy hammer type flap gate. The flue-gas denitration pretreatment device for the power plant utilizing the agriculture and forestry waste, which is provided by the invention, is used for realizing intercepting and cleaning large-particle flying ash from a boiler through the way of arranging a mechanical rotational screen nets in a high-temperature and high-dust environment, stably runs in a high-temperature environment, and is obvious in interception effect.

The base of bridge has concave shape it is composed by following: the two top of bridges are warped by the break water wall, and the middle of the bridge surface is horizontally, on the two sides of the bridge surface are a inclined plane, on it there are drain holes, protect the sea water corrode the bridge's surface, on the two sides of the pontoon bridge there is wave power electric generator, it is connected with the base of bridge, and the other end is connected with the steel wire cable. Between the base of bridge and wave generator there is safety net device.

The invention discloses a blowout preventer for water exploration and discharge drilling and a working method thereof, which belong to the technical field of coal mine safety production and include a drill pipe, an ore body and a drill hole. The drill pipe is plugged into the mine body through drilling equipment and A borehole is formed on the ore body, and the port of the borehole is located on the outer wall of the ore. A diversion mechanism is provided to guide and divert the water flowing out of the borehole. The diversion mechanism includes a fixed plate with a round hole in the center . The guide tube which is fixed on the fixed plate and has a ring structure. In the present invention, when a large amount of water gushes out inside the borehole, most of the gushing water can be diverted through the diversion cylinder, and finally discharged from the water outlet pipe at the water outlet on the diversion cylinder, thereby preventing the gushing water flow It will directly rush to the drilling rig equipment to protect the drilling rig equipment, and at the same time, it can also reduce the possibility of the impact of the gushing water flow on the people around the drilling rig equipment, so as to realize the protection of people.

The invention discloses a method for making a GCL (geosynthetic clay liner) vertical cut-off wall, and belongs to the field of seepage prevention. The method comprises the following steps of digging a groove; rolling up GCL with a round tube with the needed balance weight, fixing one end of the GCL to the top of the groove, and downwards inserting the GCL vertically along the wall of the dug groove, wherein the length of the GCL is larger than the depth of the groove; slowly unrolling to lay the GCL to the bottom of the groove along the wall from top to bottom, and fixing the GCL to the wall in an attached manner, then, taking out the round tube, and pouring slurry to the groove to carry out solidification so as to form the GCL vertical cut-off wall. The method for making a GCL vertical cut-off wall has the advantages that the effect of seepage prevention is good, and construction is easy.
