[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] UWB (Ultra Wide Band) is a wireless carrier communication technology that transmits data using nanosecond-scale, narrow, non-sinusoidal pulses rather than sinusoidal carrier waves. Therefore, it occupies a very wide spectrum. UWB technology offers advantages such as low system complexity, low transmitted signal power spectral density, insensitivity to channel fading, low interception capability, and high positioning accuracy. It is particularly suitable for high-speed wireless access in dense multipath environments, such as indoor locations.

[0028] like Figures 1 to 9 As shown, the present invention provides a concrete vibrator hose connection joint device with UWB positioning function, which is used to connect the vibrator 20 and the vibrator hose 22, and is provided with a channel for the vibrator wire to pass through. The connection joint device includes a housing assembly, and two sockets 15 connected to both ends of the housing assembly and used to connect the vibrator 20 and the vibrator hose 22. The housing assembly includes an inner housing 6 for mounting the UWB positioning tag body, an outer housing 1 that is detachably mounted on the outside of the inner housing 6, and plugs 9 for correspondingly connecting the two sockets 15 at both ends of the outer housing 1. The present invention is waterproof and shock-resistant, and strictly protects the tag from damage, thereby adding monitoring and positioning functions to the ordinary vibrator 20. The UWB positioning tag body and the vibrator 20 are cleverly connected as one, and the vibrator 20 will not have side effects such as stuck steel bars during use.

[0029] The principle of the UWB positioning tag body in the present invention is to set up 4-6 base stations on site and be equipped with a computing system. The UWB positioning tag body transmits a signal to the base station, and the position of the UWB positioning tag body on site is calculated by the length of time the information is received. The tag body is fixed on the vibrating rod 20. When the vibrating rod 20 stays in one position for too long, the computing system will calculate and issue a real-time warning to prompt the operator to move. At the same time, the computing system will record the historical trajectory from time to time. When a specific value is reached, the position in the operating area on the map that should have stayed but did not have a stop trajectory will be marked and the operator will be warned to avoid missed vibrations. Compared with other positioning functions, the positioning function of the UWB positioning tag body has the advantages of strong penetration, low power consumption, good anti-multipath effect, high security, low system complexity, and the ability to provide precise positioning accuracy, so as to avoid the phenomenon of over-vibration and missed vibration in concrete vibration as much as possible.

[0030] Preferably, Figure 2 and Figure 3 As shown, a buffer cylinder 7 is installed between the inner housing 6 and the outer housing 1. This buffer cylinder 7 is made of a vibration-resistant material, such as rubber, foam, or silicone. To facilitate installation, it stabilizes the devices within the inner housing 6 and prevents damage due to vibration. Furthermore, the outer wall of the inner housing 6 is provided with a plurality of circumferentially arranged retaining blocks. The inner wall of the buffer cylinder 7 is provided with retaining grooves 8 corresponding to the retaining blocks, thereby preventing the inner housing 6 from excessive movement within the buffer cylinder 7 and causing damage.

[0031] Preferably, Figure 2 and Figure 3 As shown, the inner shell 6 is provided with a main body compartment, a battery compartment 602 for installing a power supply device, and a transformer compartment 603 for installing a transformer. The transformer compartment 603 and the battery compartment 602 are respectively located at the two ends of the main body compartment, and the UWB positioning tag body is located in the main body compartment. The main body compartment 601 integrates a variety of sensors such as positioning and acceleration to achieve positioning and detect whether the vibrator 20 is working normally; the battery compartment 602 can supply power to the main body compartment 601, and the transformer compartment 603 contains an automatic power-off transformer. The transformer converts three-phase electricity into safe low-voltage electricity to supply power to the main body compartment 601. When the battery power is lower than a certain value, it will automatically charge the battery. When it is fully charged, the power will be cut off, and then the entire inner shell 6 will be installed in the outer shell 1. The battery compartment 602 can automatically charge the UWB positioning tag body, which almost avoids the need to replace the battery of the tag, and further extends the continuous use time.

[0032] Preferably, Figure 4 and Figure 5As shown, the outer shell 1 comprises a first cylindrical body and a second cylindrical body that are connected to each other. The butt joint end of the first cylindrical body extends along the axis of the first cylindrical body to form a flange, and the butt joint end of the second cylindrical body is provided with a slot for the flange to be inserted. This connection method is convenient and fast, and the installation speed is fast, which greatly improves the efficiency of disassembly and installation.

[0033] Preferably, Figure 2 、 Figures 4-6 As shown, the wall of the first cylinder is provided with a fixing plate 14, which is provided with a button 5 and at least one protrusion 13 spaced axially along the first cylinder. A spring is fixed to the bottom of the fixing plate 14. A cavity is provided in the first cylinder wall for accommodating and moving the fixing plate 14, and a first opening is provided on the first cylinder wall corresponding to the position of the button 5 for the button 5 to extend out, and the first opening is connected to the cavity. Furthermore, the protrusions 13 are provided in two groups, one on each opposite side of the flange, each group including two protrusions 13 spaced axially. Both protrusions 13 are fixed to the fixing plate 14 and their upward and downward movement is controlled by the spring button 5. The bottom of the fixing plate 14 is fixed with multiple springs for enabling the fixing plate 14 to move upward and downward. The flange is provided with a receiving groove for accommodating the protrusions 13. When the protrusions 13 are raised to their highest point, they protrude from the receiving groove to facilitate their insertion into the slot 8.

[0034] Preferably, Figure 7 As shown, the connection joint device also includes a transition hose 2, the socket 15 is a conductive socket sealed in the transition hose 2 or the vibrator hose 22, the plug 9 is a conductive plug, and the vibrator wire is divided into a first wire located in the transition hose 2, a second wire 12 located in the connection joint device, and a third wire 21 located in the vibrator hose 22. When the two plugs 9 are correspondingly plugged into the two sockets 15, the first wire, the second wire 12, and the third wire 21 are connected in series. The head end of the socket 15 is connected to the plug 9, and the tail end is fixed with an end plate 16. The side of the end plate 16 facing away from the socket 15 is fixed with a middle plate 17. The middle portion of the middle plate 17 has a hole for the vibrator wire to pass through. The vibrator wire passes through the hole in the middle of the middle plate 17. The outside of the vibrator wire is covered with a wire protection inner skin 18. The wire protection inner skin 18 and the socket 15 are both covered with a rubber outer skin. Cut open the inner skin 18 of the wire, cut off a section to expose the vibrator wire, and connect the wires to the copper sheet on the end plate 16 in the corresponding colors and electrodes. The copper sheet of the partition is welded to the socket 15 on the other side. The opening of the socket 15 is just enough to connect with the plug 9. Figure 4 and Figure 5As shown, the front end of the plug 9 is connected to the socket 15, and the rear end is fixed to the plug base 10. The base is blocked and fixed with a wire-threading partition 11 on the side facing away from the plug 9. The vibrator wire passes through the wire-threading partition 11 and communicates with the plug base 10, thereby ensuring that the vibrator 20 is in a conductive state when the socket 15 is inserted into the plug 9. Furthermore, the buffer cylinder 7 is formed in a form that is divided into two halves along the axial direction. It can also be directly made of incompletely formed material and inserted directly between the inner shell 6 and the outer shell 1 during installation, thereby facilitating the installation and arrangement of the second wire 12.

[0035] Preferably, Figure 5 As shown, a mortise and tenon groove is formed in the outer periphery of the conductive plug 9 in the outer shell 1 for inserting the transition hose 2 or the vibrator hose 22. The mortise and tenon groove has a deep groove, which greatly lengthens the water seepage path, thereby achieving a stable and leak-proof effect.

[0036] Preferably, Figure 1 、 2 As shown in FIG8 , fastening nuts 3 are threaded onto both ends of the outer shell 1. One end of the fastening nut 3 has an inner edge that can abut against the end of the outer shell 1. The fastening nut 3 uses the inner edge to tighten the transition hose 2 or vibrator hose 22 against the end of the outer shell 1, further enhancing the stability of the connection between the transition hose 2 or vibrator hose 22 and the connector device and preventing it from falling off during construction.

[0037] Preferably, Figure 1 、 2 As shown in Figures 8 and 9, a sleeve 19 is provided between the inner edge and the end face of the outer shell 1. A section of the fastening nut 3 close to the inner edge forms an accommodating space for the sleeve 19, and a section away from the inner edge forms a threaded section that is screwed into the outer shell 1. In this embodiment, two sleeves 19 are provided at each end of the outer shell 1, and the cross-section of the sleeve 19 is triangular. When the socket 15 is inserted into the conductive plug 9, the sleeve 19 is first put on the end of the transition hose 2 or the vibrator hose 22, and then the fastening nut 3 is put on. The sleeve 19 is gently rotated into the mortise and tenon groove to tighten it, so that the rubber outer skin of the transition hose 2 or the vibrator hose 22 extends into the mortise and tenon groove as much as possible to prevent liquid from seeping in. Finally, the end nut is rotated and tightened, so that the rubber outer skin is pressed tighter by the mortise and tenon groove.

[0038] Preferably, Figure 1 and Figure 2 As shown, the first cylinder and the second cylinder are respectively fixed with a fixing nut 4 for screwing. Since the connector device is circular, it is not convenient to screw and install, and the shape of the fixing nut 4 is convenient for the connector device to be screwed during installation.

[0039] The present invention solves the technical problem of the inconvenience of installing a positioning device on the vibrating rod in the prior art by installing a connector device with a space for storing a positioning device on the hose of the vibrating rod. The present invention uses the UWB positioning tag body in the pick-up device to send position information multiple times. The position of the vibrating rod and the length of time it stays at that position are calculated based on the length of time the information is received. This can determine whether there is over-vibration or under-vibration at the current position, and promptly issue an alarm or reminder, thereby avoiding concrete quality defects. At the same time, the connector device can also prevent the UWB positioning tag body from being damaged or falling off during the vibration process, causing damage to the positioning device.
