This utility model relates to the field of wind power yaw technology and discloses a waste oil collection device for the maintenance of a wind turbine yaw system. The device includes a yaw main wheel and a track component. The track component includes a calibration plate with a fixing groove at the top. A fixing component is inserted into the inner wall of the fixing groove, and a snap-fit ​​component is fixed to the bottom of the inner wall of the fixing groove. A snap-fit ​​groove is formed at the bottom of the fixing component, and the inner wall of the snap-fit ​​groove is snap-fitted to the surface of the snap-fit ​​component. A sloping shovel is fixed to the side of the fixing component away from the calibration plate, and a backhoe is fixed to the side of the sloping shovel closer to the bottom of the calibration plate. This utility model secures the fixing component to the fixing groove of the calibration plate, ensuring that the bottom of the sloping shovel and the backhoe are tightly fitted to the top of the calibration plate. Thus, during the forward rotation of the yaw main wheel, the sludge on the inner wall of the yaw main wheel is scooped up by the sloping shovel, and the backhoe similarly scoops up the sludge during the reverse rotation. Workers only need to clean the sloping shovel and backhoe periodically.

The utility model discloses a kind of cooling devices for casting production of high efficiency energy saving, it is related to casting production technical field, including base and support frame, the support frame is set on the base, further include cooling mechanism, set on the support frame;Heat dissipation mechanism, set on the support frame, the heat dissipation mechanism includes: mounting, have two, and two mounting are set in the support frame;Mounting bracket, mounting bracket is set in the mounting;Driving motor, set in the mounting bracket;Fan blade, the driving motor output end;Fixed plate, set on the mounting piece.This device is discharged in time to the heat generated inside this device by setting heat dissipation mechanism, accelerates the cooling work of this device, can also collect water vapor in time, can also prevent water vapor from leaving the interior of this device in large quantities, ensure the use of water source.

This invention relates to a modular heat recovery tower comprising at least a first module and a second module stacked together. The first module includes a first mounting structure at least at its upper edge, the first mounting structure comprising a vertical portion and an outwardly oriented horizontal portion, and the second module includes a second mounting structure at least at its lower edge, the second mounting structure comprising a vertical portion and an outwardly oriented horizontal portion. The first and second mounting structures are adapted to mate with each other. At least one sealing strip is disposed between the horizontal portions of the first and second mounting structures. The sealing strip is part of a sealing member that further includes a compressible profile seal, and the compressible profile seal is connected to the sealing strip. The compressible profile seal is configured to abut against the junction of the horizontal and vertical portions of the first mounting structure.

The utility model relates to light material conveying and drying equipment which comprises a conveying belt body, an upper cover body and a drying fan. The upper cover body is installed on the upper portion of the conveying belt body, the edges of the two sides of the upper cover body are kept to be connected with the conveying belt body in a sealed mode, and the front end and the rear end of the upper cover body are provided with material ports used for feeding and discharging respectively. The drying fan is installed on the lower side of the conveying belt body and located on the lower portion of the front side of the upper cover body, and an air outlet of the drying fan faces the conveying belt body. The conveying belt is reasonable in structural design, the upper cover body and the lower cover body are additionally arranged on the conveying belt body, so that a relatively closed space used for preventing materials from leaving the surface of the conveying belt is formed, meanwhile, an air circulation channel is formed based on the internal structure, the materials can be normally conveyed in the drying process, and therefore the working efficiency is improved.

The utility model relates to the technical field of livestock breeding equipment, concretely to a device of cattle stable weighing, including base and four door columns, the top of base is connected with door column fixedly, the top of base is provided with the weighter, both sides of base all are connected with the inclined plate fixedly, and a plurality of railings are fixedly connected between every two far away door columns, the utility model drives the gear to rotate through the drive motor in the fixed block, since the gear is engaged with the rack plate, when the gear rotates then will drive the rack plate to move to the inside of weighing equipment, when the rack plate moves to the inside of weighing equipment will drive the baffle to move synchronously, since having two baffles, and the baffle is opposite setting, when two baffles all move to the inside of weighing equipment will contact each other, and the advancing route of cattle is blocked, thereby making cattle movable space reduce, and thereby reducing the activity range and frequency of cattle, and thereby increasing the precision of weighing.

The utility model provides an energy harvesting type capacitor, which relates to the technical field of energy storage capacitors, and comprises a capacitor main body, a clamped piece is arranged at the top of the capacitor main body, a parallel transverse clamping groove is arranged on one side of the clamped piece, and the edge of the inner wall of the parallel transverse clamping groove is a fillet. The capacitor is generally large in size and dead weight, most of the capacitor is cylindrical, the surface of the capacitor is smooth and lacks stress points, the capacitor is prone to falling off in the clamping process, the installation difficulty is increased, the working efficiency is reduced, and in order to ensure the clamping stability, the clamping force of a clamping assembly needs to be greatly increased, so that the clamping efficiency is greatly improved. However, the increased clamping force can cause scratching of the surface of the capacitor, so that scratches are generated, even the outer layer of the capacitor is damaged, and internal substances flow out, which not only can influence the performance and the service life of the capacitor, but also can cause damage to the whole circuit system.

The utility model relates to water gauge technical field, and disclose a kind of convenient replacement's intelligent water gauge, including intelligent water gauge main body, connecting pipe piece and water pipe main body, connecting pipe piece inner wall is fixed with fixed ring, and multiple inverted ladder ring parts are fixed with the fixed ring top circumferential array.This utility model is extruded the outer inclined surface of pressure head by the pressure ring part of hollow screw piece bottom, so that inverted ladder ring part is deformed along with, outer inclined surface gathers the outer peripheral surface of water pipe main body to center, so that the direct fixation between intelligent water gauge main body and water pipe main body is made, improve work efficiency, reduce the material and operating cost required, and direct mechanical connection is formed between the two, and overall structure rigidity and anti-interference ability greatly increase;While the bolt part of hollow screw piece is hidden in connecting pipe piece inner wall, better prevent the deformation of thread caused by collision in transportation, installation and use process, cause difficult installation and disassembly, so as to improve the maintenance efficiency and system reliability of intelligent water gauge main body.
