This invention relates to the field of shower head life testing, and more particularly to a device for testing the lifespan of shower head switching and ball head oscillation. The device includes a test frame and a movable component fitted onto the outside of an arc-shaped frame. The test frame includes an arc-shaped frame and positioning rods at both ends of the arc-shaped frame. The positioning rods are axially rotatably fixed to the shower head mounting rod. The movable component moves along the arc-shaped frame. A telescopic rod is connected to the side of the movable component near the positioning rods. A positioning frame is fixed to the end of the telescopic rod, and the interior of the positioning frame is filled with a positioning element made of elastic material. This invention, through the cooperation between the arc-shaped frame and the movable component, combined with the rotatability of the positioning rods, can control the free positioning of the movable component within a spherical space. Combined with the use of a universal ball head fixing method for the shower head, it ensures that the shower head is fixed by the positioning element and can be freely adjusted within the spherical space for testing. Only a random path needs to be set to simulate the uncertainty of human operation.

A time grating sensor for spherical multi-dimensional rotation angle measurement. The time grating sensor comprises a stator base body (1) and a rotor base body (2). The stator base body (1) is spherical shell-shaped, the rotor base body (2) is spherical and located in the spherical shell of the stator base body (1), and a gap is reserved between the surface of the rotor base body (2) and the inner surface of the stator base body (1), so that the rotor base body (2) is suspended and concentric with the stator base body (1). Six excitation units having the same shape and size are uniformly distributed at intervals on the inner surface of the stator base body (1). The centers of the six excitation units are located at the centers of six faces of a cube externally tangent to the inner surface of the stator base body (1). Eight sensing units having the same shape and size are uniformly distributed at intervals on the surface of the rotor base body (2). The eight sensing units are respectively symmetrically distributed on eight quadrants of a space rectangular coordinate system taking the center of the rotor base body (2) as the origin. Also disclosed is a mounting structure for the time grating sensor for spherical multi-dimensional rotation angle measurement. The solution above can realize high-accuracy multi-dimensional rotation angle measurement in a spherical space, simple structure, thorough decoupling, and strong anti-interference capability.

This invention discloses a rapid positioning welding jig for spherical nodes in a space frame and its usage method, relating to the field of welded spherical space frame assembly construction technology. It includes a welding base, a member positioning device, an adjustable base for the support rod, a member support rod, and a top support. The welding base is used to place the welded sphere. The member positioning device is sleeved on the welded sphere to achieve precise layout of the contact position between the member and the welded sphere. The adjustable base for the support rod is arranged around the welding base, and the member support rod is installed on the adjustable base. The top support is hinged to the top of the member support rod to support one end of the member. The other end of the member is welded and fixed to the welded sphere. The rapid positioning welding jig for spherical nodes in a space frame provided by this invention and its usage method solve the problems of difficulty in ensuring positioning accuracy, cumbersome installation and dismantling of fixing devices, difficulty in moving them, high construction safety risks, and difficulty in controlling welding deformation in the prior art.

This product is an ice maker for producing spherical ice, and consists of an outer container with an open top and an inner container that has a flange and is separable into two parts, and when assembled, a spherical space for pouring ice-making liquid is formed inside, with the part excluding the flange being housed within the outer container.

This invention relates to a temporary lifting device, system, and lifting method for a spherical node in a space frame, and pertains to the field of construction technology for the overall lifting of welded spherical space frames. It includes a welded sphere, steel sleeves, stiffening plates, and a base plate. Steel sleeves are connected to the top and bottom of the welded sphere, and the bottom steel sleeve is connected to the base plate. A stiffening plate is welded between the base plate and the welded sphere. This invention solves the problems of existing technologies, such as the inability to reuse temporary scaffolding, low utilization rate, long construction period, long rental period for large lifting equipment, high cost, and high safety risks associated with high-altitude operations.

This invention discloses a construction method for the internal support structure of a spherical building, comprising: constructing the main body of the spherical space frame and reserving hanging nodes; dividing the internal support structure along its height into a lower support area, a middle transition area, and a top operating area, and constructing it using a zoned reverse construction method; first installing the lower support area, then assembling the annular ring beam and platform plate of the top operating area into an operating platform unit, lifting the whole to the design elevation and fixing it with the hanging nodes to form a high-altitude work platform; subsequently using this platform to complete the installation of the middle transition area, making the various areas connected to form a whole. This method transforms the permanent top structure into a construction platform, completely replacing full-span scaffolding, significantly saving on scaffolding material rental, transportation, and labor costs, avoiding the impact of scaffolding loads on the floor slabs, and freeing up internal working space. It is particularly suitable for renovation or cross-construction projects where the main structure is already enclosed, the space is cramped, and there is no large hoisting channel.
