Description

Technical Field

[0001] This utility model relates to the field of electromagnetic radiation monitoring technology, specifically to a probe bracket and a probe for electromagnetic radiation monitoring. Background Technology

[0002] In substation electromagnetic radiation monitoring, accurate measurement of electric or magnetic field strength is crucial. Monitoring probes are typically based on specific sensing principles (such as dipole antennas or Hall effect sensors), and are highly directional. The accuracy of the measurement results depends heavily on the probe's orientation (horizontal or vertical) relative to the measured field. If the probe fails to maintain the correct horizontal or vertical position, it will directly lead to distorted measurement data, affecting the reliability of electromagnetic environment assessment.

[0003] Currently, traditional tripods are commonly used to fix probes in field monitoring. However, substation environments often have uneven ground, gravel, or slopes, making the tripods unstable. To ensure the probe is horizontal or vertical, operators need to frequently and precisely adjust the length of each of the three legs of the tripod. This process is cumbersome, time-consuming, and labor-intensive, and it is difficult to quickly achieve the ideal state under high-precision requirements, significantly reducing the efficiency of monitoring work. This deficiency is particularly prominent in situations requiring multiple locations and rapid deployment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a probe bracket and a probe for electromagnetic radiation monitoring, so as to solve the problem that the process of adjusting the probe posture with the existing triangular bracket is cumbersome, time-consuming and laborious.

[0005] This utility model is achieved through the following technical solution:

[0006] A probe holder includes a spherical movable ball and a fixed sleeve fitted over the movable ball. The movable ball and the fixed sleeve are spherically hinged, and the top of the movable ball extends through the top wall of the fixed sleeve and out of the fixed sleeve.

[0007] A connecting column is provided above the movable ball. One end of the connecting column is fixedly connected to the top of the movable ball, and the other end extends radially toward the movable ball. The center of gravity of the movable ball and the connecting column as a whole is located below the center of the ball. When the movable ball is naturally placed on the fixed sleeve, the connecting column is in a vertical state.

[0008] A locking part is provided between the movable ball and the fixed sleeve to restrict the rotation of the movable ball.

[0009] Furthermore, the top surface of the fixed sleeve is provided with a through hole, the top end of the movable ball extends out from the top opening of the through hole, and the diameter of the connecting post is smaller than the size of the top opening of the through hole;

[0010] The sidewall of the through hole is curved and fits the outer spherical surface of the movable ball, and the center of the movable ball is located inside the fixed sleeve.

[0011] Furthermore, the bottom of the movable ball extends from the bottom opening of the through hole and is connected to a hook, which is located on the extension line of the connecting column.

[0012] Furthermore, a blind hole is provided on the end face of the top of the connecting column, the blind hole extending radially toward the movable ball and extending to below the center of the movable ball.

[0033] Please see Figure 1-4 The present invention provides a technical solution: a probe bracket, comprising a movable ball 1 in the shape of a sphere and a fixed sleeve 2 sleeved outside the movable ball 1, wherein the movable ball 1 and the fixed sleeve 2 are connected by a ball hinge, and the top end of the movable ball 1 extends out of the fixed sleeve 2 through the top wall of the fixed sleeve 2.

[0034] A connecting column 11 is provided above the movable ball 1. One end of the connecting column 11 is fixedly connected to the top of the movable ball 1, and the other end extends radially toward the movable ball 1. The center of gravity of the movable ball 1 and the connecting column 11 as a whole is located below the center of the ball. When the movable ball 1 is naturally placed on the fixed sleeve 2, the connecting column 11 is in a vertical state.

[0035] A locking part is provided between the movable ball 1 and the fixed sleeve 2 to restrict the rotation of the movable ball 1.

[0036] In this design, the probe is connected to the connecting column 11 on the movable ball 1, and connected to the ground or wall surface using the fixed sleeve 2. The movable ball 1 and the fixed sleeve 2 are connected by a ball hinge, and the center of gravity of the movable ball 1 and the connecting column 11 is located below the center of the ball. When the fixed sleeve 2 is installed on uneven or inclined ground, the movable ball 1 rotates under the action of gravity, automatically adjusting the connecting column 11 to a vertical position, and the movable ball 1 is fixed by the locking part, providing a stable installation base for the probe. The operation is simple and convenient.

[0037] The top part of the movable ball 1 is cut off to form a platform. The plane of the platform is perpendicular to the axis of the connecting column 11, and the connecting column 11 is set on the platform. The connecting column 11 and the platform can be detachably fixed (e.g., threaded connection, adhesive bonding, etc.). By removing the connecting column 11, the platform becomes a flat horizontal surface, and the probe can be directly installed on the platform.

[0038] In cases where probes have sockets, the diameter of the connecting post 11 can be set to match the diameter of the socket, allowing for quick probe installation by directly inserting the connecting post 11 into the socket.

[0039] In addition, the mass of the connecting column 11 is less than the mass of the cut-off part of the movable ball 1, so that the masses of the upper and lower parts of the center of the movable ball 1 are not equal. By designing the mass difference between the connecting column 11 and the cut-off part, the center of gravity is ensured to shift downward and move to below the center of the movable ball 1.

[0040] In this embodiment: the top surface of the fixed sleeve 2 is provided with a through hole 21, the top end of the movable ball 1 extends out from the top opening of the through hole 21, and the diameter of the connecting post 11 is smaller than the size of the top opening of the through hole 21;

[0041] The sidewall of the through hole 21 is curved and fits the outer spherical surface of the movable ball 1, and the center of the movable ball 1 is located inside the fixed sleeve 2.

[0042] In this design, the fixed sleeve 2 is fitted outside the middle of the movable ball 1, and the center of the movable ball 1 is located inside the fixed sleeve 2, so that the size of the openings at both ends of the through hole 21 is smaller than the diameter of the movable ball 1, which can restrict the movable ball 1 from moving out of the fixed sleeve 2 and falling off.

[0043] The diameter of the connecting post 11 is smaller than the size of the opening at the top of the through hole 21, so that the movable ball 1 has a certain range of rotation. When in use, the position of the fixing sleeve 2 can be initially adjusted by visual inspection (close to the horizontal state), and then the movable ball 1 can be automatically rotated by gravity for fine adjustment so that the connecting post 11 is in a vertical state.

[0044] Alternatively, the sidewalls of the through hole 21 and the outer spherical surface of the movable ball 1 can be ground and polished, or coated with a low-friction coefficient paint (such as Teflon) to reduce the friction between them and ensure that the movable ball 1 can rotate freely and reset by gravity.

[0045] In this embodiment: the bottom of the movable ball 1 extends out from the bottom opening of the through hole 21 and is connected to a hook 12, the hook 12 being located on the extension line of the connecting post 11.

[0046] In this solution, the hook 12 can be directly fixed to the movable ball 1, or the hook 12 can be suspended from the movable ball 1 using a rope. The hook 12 is used to hang counterweights, and a vertical downward pulling force is applied to the intersection of the outer spherical surface of the movable ball 1 and the extension line of the connecting column 11, which helps the movable ball 1 rotate and reset, and keeps the connecting column 11 in a vertical state.

[0047] In this embodiment: a blind hole 13 is provided on the end face of the top of the connecting column 11. The blind hole 13 extends radially toward the movable ball 1 and extends to below the center of the movable ball 1.

[0048] In this design, the blind hole 13 can further reduce the mass of the upper part of the center of the movable ball 1, increase the mass difference between the upper and lower parts of the center of the ball, and further lower the center of gravity.

[0049] Alternatively, a fluid medium (such as silicone oil, perfluoropolyether oil, etc.) can be added into the blind hole 13, with the filling height lower than the center height of the movable ball 1, to prevent the fluid medium from being thrown out during the rotation of the movable ball 1 (a cap can be installed to block the opening of the blind hole 13).

[0050] When the movable ball 1 rotates or swings, the fluid medium 14 flows within the blind hole 13, thereby generating a damping effect and suppressing the ball's swing. The principle is as follows:

[0051] Viscous resistance energy dissipation: When the movable ball 1 swings, the fluid medium 14 in the blind hole 13 will lag behind the movement of the movable ball 1 due to inertia, resulting in relative movement between the fluid medium 14 and the hole wall of the blind hole 13, and between the layers inside the fluid medium 14. High viscosity fluid (such as silicone oil) can enhance the viscous resistance effect, so that some mechanical energy is converted into heat energy (energy dissipation), thereby slowing down the swing of the movable ball 1.

[0052] Inertial hysteresis effect: Due to inertia, the fluid medium 14 will not immediately follow the movement of the moving ball 1, causing the fluid to sway within the blind hole 13, generating a reaction force opposite to the swaying direction, which further suppresses the swaying.

[0053] In this embodiment: a threaded hole 22 is provided on the side wall of the fixed sleeve 2, and the locking part includes a screw 3. One end of the screw 3 passes through the threaded hole 22 and abuts against the movable ball 1, and the screw 3 and the threaded hole 22 are connected by a threaded engagement.

[0054] In this design, the screw 3 is threaded into the threaded hole 22. With the screw 3 pressing against the movable ball 1, tightening the screw 3 applies a positive pressure along its axial direction to the movable ball 1, increasing the friction between them. Even without polishing or applying a low-friction coefficient coating to the outer surface of the movable ball 1, the frictional force restricts its rotation on the fixed sleeve 2, thus locking and fixing the movable ball 1.

[0055] A prism-shaped groove can be made on the inner wall of the fixed sleeve 2 at the end of the threaded hole 22 facing the movable ball 1. A friction plate 31 (rubber plate) is slidably fitted in the groove along the axial direction of the threaded hole 22 with a single degree of freedom. The end of the screw 3 facing the movable ball 1 is inserted into the friction plate 31 and rotated to engage. By rotating the screw 3, the friction plate 31 is driven to move closer to or away from the movable ball 1, and the rubber pad contacts and abuts against the movable ball 1.

[0056] In this embodiment: the threaded hole 22 extends radially toward the movable ball 1.

[0057] In this scheme, by setting the threaded hole 22 to extend radially toward the movable ball 1, the screw 3 applies radial pressure to the movable ball 1, thereby reducing the probability that the movable ball 1 will be pushed and deflected.

[0058] In this embodiment, the end face of the screw 3 facing the movable ball 1 is curved and is adapted to the outer spherical surface of the movable ball 1.

[0059] In this design, the end face of the screw 3 is curved, which allows it to make stable contact with the movable ball 1, increasing the contact area and thus increasing the friction force, making the locking effect more stable.

[0060] In this embodiment: a support plate is provided below the fixed sleeve 2. The support plate includes a vertical plate 23 and a horizontal plate 24 that are perpendicular to each other. The two ends of the vertical plate 23 and the horizontal plate 24 facing each other are fixedly connected.

[0061] The vertical plate 23 is fixedly connected to the side wall of the fixed sleeve 2 at one end facing away from the horizontal plate 24, and the horizontal plate 24 is parallel to the top surface of the fixed sleeve 2.

[0062] In this solution, the vertical plate 23 can be used to connect with relatively vertical planes such as walls, and the horizontal plate 24 can be used to connect with relatively horizontal planes such as the ground. Compared with the tripod, this bracket can be used in more complex scenarios and has high practicality.

[0063] In this embodiment, both the vertical plate 23 and the horizontal plate 24 are provided with locking holes 25.

[0064] In this design, the locking hole 25 is used to insert expansion bolts and other connecting parts. By inserting the expansion bolts through the locking hole 25 into the installation foundation, the bracket can be fixedly installed. The bracket can be fixedly installed at commonly used monitoring points in the substation without the need for frequent installation and debugging, thus facilitating monitoring work.

[0065] An electromagnetic radiation monitoring probe includes the aforementioned probe bracket and probe body 4, wherein the connecting post 11 is detachably fixedly connected to the probe body 4.

[0066] In this solution, the probe body 4 can be selected as an EHP-50F power frequency electromagnetic field probe. A threaded sleeve is provided at the bottom. By opening a matching external thread on the outer circle surface of the connecting column 11 of the probe bracket, the connecting column 11 is inserted into the threaded sleeve and the probe body 4 is fixedly installed on the probe bracket through thread engagement. It can also be disassembled for easy storage and transportation.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
