This utility model discloses a detection head fixing assembly for an automatic inspection machine, belonging to the technical field of automatic inspection machines. It includes a mounting plate, a connecting plate mounted on the front of the mounting plate, and a detection head body fixedly connected to the front of the connecting plate, along with a locking device assembled within the connecting plate. In this utility model, a return spring provides a return force during the movement of the sliding rod, assisting the limiting plate in quickly returning to its original position upon release, thus improving operational efficiency. Furthermore, a circular plate is sleeved on the sliding rod via a bearing, forming a sliding fit with the sleeve, ensuring smooth movement of the sliding rod during pushing and rotating, and preventing jamming. In summary, this utility model, through the coordinated cooperation of the sliding rod, the limiting plate, the transverse groove, and the limiting slot, achieves rapid insertion, rotational positioning, and stable locking of the detection head body, possessing technical advantages of quick installation, reliable structure, and simple operation, significantly improving the efficiency and assembly safety of the inspection equipment.

The present invention provides a manually operated diaphragm valve that maintains compactness through a simple construction while simultaneously allowing for setting the valve body's opening and closing range. This design is unaffected by individual differences in the valve's internal shape, ensuring sufficient flow rate when fully open, and also allowing for arbitrary adjustment of the fully open flow rate. The valve body 1 includes a valve body 12 assembled inside a main body 10 and a main shaft 13 threaded into the main body 10 in a lifting motion, separating the valve body 12 from the valve seat 14. A handle 2 is mounted above the valve body 1 for manually rotating the main shaft 13. Near the upper part of the valve body 1, a fully open position adjustment mechanism 20 is provided. This mechanism restricts the rotation of the handle 2 on the fully open side, setting the upper limit of the flow rate of the valve body 12 when fully open.

This invention discloses an underwater equipment installation device, including a support body, an insertion component, a power storage component, a triggering component, and a deployment component. The support body is used to support and position the underwater equipment. The insertion component is fixed to the underwater equipment and is used to insert into an underwater substrate. The power storage component is disposed at one end of the insertion component and is used to apply force to the insertion component after triggering to insert it into the underwater substrate. The triggering component is fixed to the support body and is used to trigger the power storage component. The deployment component is disposed on the outer periphery of the insertion component and has a retracted state and an deployed state. After the insertion component is inserted, the deployment component unfolds along the insertion direction perpendicular to the insertion component and inserts into the underwater substrate, changing from the retracted state to the deployed state. This invention aims to solve the technical problem in the prior art that underwater equipment is difficult to stably insert and maintain in place in an underwater environment due to water flow disturbance and the influence of soft underwater foundations.

The present application relates to a precast pile plug-in lock joint, comprising: an upper sleeve, a bottom end of which is provided with a plug rod, a bottom end of the plug rod is provided with a first connecting structure, an outer circumferential wall of the plug rod is provided with an outer lock piece capable of being elastically deformed in a radial direction, the outer lock piece is provided with a second connecting structure and a first combining surface; a lower sleeve, a top end of which is provided with an opening for inserting the plug rod, a bottom of the lower sleeve is provided with an inner lock piece capable of being elastically deformed in a radial direction, an inner wall of the inner lock piece is provided with a third connecting structure matched with the first connecting structure and a second combining surface matched with the first combining surface, and an inner wall of the lower sleeve is provided with a fourth connecting structure matched with the second connecting structure; after the plug rod is inserted into place, the first combining surface is attached to the second combining surface, so as to form double self-locking between the second connecting structure and the fourth connecting structure and between the third connecting structure and the first connecting structure when being pulled.
