Description

Technical Field

[0001] This utility model relates to the field of level measuring instrument technology, and in particular to a level detection device and a level adjustment device. Background Technology

[0002] As a high-precision crystal growth device, the growth quality of single crystals is affected by the levelness of the pulling head of the single crystal furnace.

[0003] Currently, the following two situations can generally be used to determine if there is a problem with the level of the lifting head: one is that the tungsten wire rope is found to be shaking during operation, and the other is that it is found to be level during calibration during regular maintenance.

[0004] However, both of these methods of judging whether there is a problem with the level of the lifting head have a large lag. Problems with the level of the lifting head will make the monocrystalline silicon rod prone to wire breakage and misalignment, affecting the production quality of the monocrystalline silicon rod. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a level detection device to detect changes in the level of the lifting head in a timely manner.

[0006] To solve the above-mentioned technical problems, this utility model provides a horizontal detection device, including an insulating shell, a conductive strip, a conductive liquid, and a conductive path. The top of the insulating shell is provided with a concave part. The conductive strip is arranged along the outer periphery of the concave part and is connected to the conductive path. The conductive liquid partially covers the concave part. In the initial state, the conductive liquid is located at the center of the concave part and is in contact with the conductive path.

[0007] The conductive path is connected to the power supply and the electronic indicator. When the insulating shell is tilted within the first preset tilt angle range, the conductive liquid comes into contact with the conductive strip and the conductive path, and the power supply supplies power to the electronic indicator.

[0008] This invention features a concave portion on the top of an insulating housing, with a conductive strip along its outer periphery. The concave portion is partially covered by conductive liquid, and the conductive path connects to a power source, an electronic indicator, and the conductive strip. Since the conductive liquid is initially equidistant from the conductive strip and maintains contact with the conductive path, and when the insulating housing tilts within a first preset tilt angle range, the conductive liquid contacts the conductive strip and the conductive path. Specifically, when the insulating housing tilts at a certain angle, the conductive liquid shifts in the concave portion, enabling circuit continuity. The power source supplies power to the electronic indicator, which provides immediate alerts and warnings regarding the tilt of the insulating housing.

[0009] Connecting a level detection device to the device under test allows the determination of whether the device is level. The conductive liquid in the level detection device flows downwards using the potential energy generated when the device is tilted. When the conductive liquid reaches the corresponding conductive strip and conductive path, a closed loop is formed. An electronic indicator within this closed loop indicates the tilt direction, allowing the user to clearly and accurately determine which direction the tilt has occurred and make necessary adjustments.

[0010] As an improvement to the above solution, when the insulating shell is tilted within the second preset tilt angle range, the conductive liquid remains in contact with the conductive passage;

[0011] The second preset tilt angle range is 0 to a°, and the first preset tilt angle range is b to c°, where 0 < b < c ≤ a.

[0012] In the initial state, the conductive liquid is in contact with the conductive path, but not with the conductive strip. Within a certain tilt angle range, the conductive liquid maintains contact with both the conductive path and the conductive strip, so that the power supply powers the electronic indicator and indicates that a tilt has occurred.

[0013] As an improvement to the above solution, the concave surface is provided with a spherical arc surface, a conical surface, or a frustum surface that is recessed downwards.

[0014] This invention uses a concave surface, such as a spherical arc, a conical surface, or a frustum, to create a concave portion. The detection sensitivity of the horizontal detection device can be adjusted by changing the curvature of the concave portion, making the detection sensitivity more suitable for the user's actual needs. Furthermore, making the concave portion curved reduces the flow resistance of the conductive liquid.

[0015] As an improvement to the above solution, the conductive strips are arranged in a circumferential array along the concave surface, and a first preset distance is provided between adjacent conductive strips.

[0016] As an improvement to the above solution, the conductive strip is arc-shaped.

[0017] This invention increases the probability of contact between the conductive strips and the conductive liquid in all directions by circumferentially arraying conductive strips on the concave surface, thus improving the reliability of tilt angle detection.

[0018] As an improvement to the above solution, the insulating shell is provided with a first connection hole and a second connection hole. The first connection hole passes through the concave part and is always covered by the conductive liquid when the concave part is facing upward. The second connection hole is located below the conductive strip. The conductive path passes through the first connection hole and is electrically connected to the conductive liquid. The conductive path passes through the second connection hole and is electrically connected to the conductive strip.

[0019] This invention allows the conductive liquid to be connected to an external power source by providing a first connection hole in the cavity, and enables the conductive path to be connected to the conductive strip by providing a second connection hole.

[0020] As an improvement to the above solution, the first connecting hole is located at the center of the concave portion.

[0021] The first connection hole is placed in the center of the concave part, so that each circuit corresponding to the conductive strip can share a section of circuit, simplifying the circuit layout.

[0022] As an improvement to the above solution, the electronic indicator is configured to correspond to the conductive strip.

[0023] This invention, by setting an electronic indicator corresponding to each conductive strip, can provide a prompt when the corresponding line is conductive, allowing users to comprehensively and accurately determine which line is tilted in the correct direction.

[0024] As an improvement to the above solution, the top of the insulating shell is provided with an insulating cover, and the conductive liquid is disposed in the closed space formed by the insulating cover and the insulating shell.

[0025] In addition, this utility model also provides a leveling device, characterized in that it includes the above-mentioned leveling detection device, and further includes a switch component and a drive mechanism connected to the conductive path. The insulating housing is installed on the lifting head, and the drive mechanism is connected to the foot of the lifting head. When the switch component is turned on, the drive mechanism drives the foot to extend or retract.

[0026] This invention, by setting up a switch component and a drive mechanism, can adjust the tilt in a certain direction when the device under test tilts. This is achieved by activating the switch component of the corresponding line and using the drive mechanism to control the extension and retraction of the feet of the device under test. This simplifies the tilt adjustment process and improves the convenience and user experience. Attached Figure Description

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown, this utility model discloses one embodiment of a horizontal detection device. The horizontal detection device is connected to the device to be detected. In some embodiments, the device to be detected can be the lifting head of a single crystal furnace. Understandably, the device to be detected can also be other devices that need to be detected to see if they are in a horizontal state. This utility model does not limit this.

[0033] The horizontal detection device includes an insulating housing 1, a conductive strip 2, a conductive liquid 3, and a conductive passage 4. The top of the insulating housing 1 is provided with a concave part 11. The conductive strip 2 is arranged along the outer periphery of the concave part 11 and is connected to the conductive passage 4. The conductive liquid 3 partially covers the concave part 11. The conductive liquid 3 is equidistant from all points of the conductive strip 2 at its initial position and maintains contact with the conductive passage 4. The conductive passage 4 is connected to a power supply 5 and an electronic indicator. When the insulating housing 1 is tilted within a first preset tilt angle range, the conductive liquid 3 contacts the conductive strip 2 and the conductive passage 4, so that the power supply 5 supplies power to the electronic indicator.

[0034] In this embodiment, a concave portion 11 is provided on the top of the insulating housing 1, and a conductive strip 2 is provided along the outer periphery of the concave portion 11. The concave portion 11 is partially covered by conductive liquid 3, and the conductive path 4 is connected to the power supply 5, the electronic indicator, and the conductive strip 2. Since the conductive liquid 3 is equidistant from the conductive strip 2 at its initial position and maintains contact with the conductive path 4, and when the insulating housing 1 tilts within a first preset tilt angle range, the conductive liquid 3 contacts the conductive strip 2 and the conductive path 4. That is, when the insulating housing 1 tilts at a certain angle, the conductive liquid 3 shifts in the concave portion 11, thus achieving circuit conduction. The power supply 5 supplies power to the electronic indicator, which provides an immediate warning and alarm for the tilt of the insulating housing 1, helping to detect changes in the horizontal position of the lifting head in a timely manner during crystal growth.

[0035] In this embodiment, the insulating shell 1 is made of an insulating material, preferably ceramic, glass, or plastic, but can also be made of other insulating materials; this invention does not limit this. The conductive strip 2 is made of a solid conductor, preferably copper, but can also be made of other metals such as gold, silver, iron, tin, or aluminum. The conductive liquid 3 is a conductive liquid, preferably mercury, but can also be a soluble acid, alkali, or salt solution such as sodium chloride solution.

[0036] The top of the insulating housing 1 is provided with an insulating cap (not shown) to prevent the conductive liquid 3 from overflowing or leaking. The conductive liquid 3 is disposed within the enclosed space formed by the insulating cap and the insulating housing 1. The insulating cap is preferably made of a transparent material such as glass or resin board, so that the volume and flow of the conductive liquid 3 can be observed.

[0037] When the insulating shell 1 is tilted within the second preset tilt angle range, the conductive liquid 3 remains in contact with the conductive passage 4. The first preset tilt angle range is included within the second preset tilt angle range. The second preset tilt angle range is 0 to a°, and the first preset tilt angle range is b to c°, where 0 < b < c ≤ a, and a ≤ 90°.

[0038] The second preset tilt angle range includes 0°, while the first preset tilt angle range does not include 0°. That is, in the initial state, the conductive liquid 3 is in contact with the conductive passage 4, but the conductive liquid 3 is not in contact with the conductive strip 2, and the distance between the conductive liquid 3 and the conductive strip 2 is equal at all points in the initial position. At this time, the conductive strip 2 set on the outer periphery of the concave part 11 is in a horizontal state.

[0039] The first preset tilt angle range and the second preset tilt angle range can be adjusted by changing the curvature or tilt angle of the concave part 11, or by changing the volume ratio of the conductive liquid 3 in the concave part 11.

[0040] The curvature or inclination angle of the concave surface 11, as well as the volume of the conductive liquid 3, affect the sensitivity of the horizontal detection. Higher sensitivity can be achieved by reducing the curvature or slope (i.e., making the surface of the concave surface 11 smoother) or by increasing the amount of conductive liquid 3; lower sensitivity can be achieved by increasing the curvature or slope (i.e., making the surface steeper) or by reducing the amount of conductive liquid 3.

[0041] When the insulating housing 1 is set horizontally, the conductive liquid 3 only contacts the conductive passage 4, and the conductive liquid 3 maintains a second preset distance from the conductive strip 2. At this time, the circuit does not form a closed loop, and the electronic indicator does not work.

[0042] When the insulating shell 1 tilts, the conductive liquid 3 comes into contact with the conductive passage 4 and the conductive strip 2, forming a closed circuit. The power supply 5 supplies power to the electronic indicator, which then provides immediate prompts and alarms.

[0043] In this embodiment, the concave surface 11 is preferably a continuous and smooth curved surface to reduce the flow resistance of the conductive liquid 3.

[0044] More preferably, the concave portion 11 is arranged in a rotationally symmetrical manner, and the conductive strips 2 are arranged in a circumferential array along the concave portion 11, so that when the insulating housing 1 is tilted in any direction at an angle that falls within the second preset tilt angle range, the circuit can be turned on, and the electronic indicator can work.

[0045] In this embodiment, the concave part 11 is provided with a spherical arc surface, a conical surface or a frustum surface that is recessed downwards. The resistance of the conductive liquid 3 flowing in all directions of the concave part 11 is the same, so that the sensitivity of the device is consistent in all directions.

[0046] The conductive strip 2 is preferably an arc shape concentric with the concave surface 11, and a first preset distance is provided between adjacent conductive strips 2. The first preset distance is small enough to ensure insulation between each conductive strip 2, which increases the probability of contact between the conductive strip 2 and the conductive liquid 3 in all directions, resulting in high reliability of tilt angle detection. In addition to setting a first preset distance between adjacent conductive strips 2 to ensure insulation when the conductive liquid 3 is not flowing through, an insulator can also be provided between each conductive strip 2.

[0047] The insulating housing 1 is provided with a first connecting hole 12 and a second connecting hole 13 for conducting electricity or threading. A conductive coating or conductive post can be disposed within the first connecting hole 12 and the second connecting hole 13, or the wire of the conductive path 4 can be directly fixed therein. The conductive coating, conductive post, or wire in the first connecting hole 12 and the second connecting hole 13 all serve as part of the conductive path 4. The first connecting hole 12 penetrates the concave portion 11 and is always covered by the conductive liquid 3 when the concave portion 11 is facing upwards. The second connecting hole 13 is located below the conductive strip 2. The conductive path 4 passes through the first connecting hole 12 and is electrically connected to the conductive liquid 3, and passes through the second connecting hole 13 and is electrically connected to the conductive strip 2.

[0048] Preferably, in this embodiment, the first connection hole 12 is located at the center of the concave surface 11, and each circuit can share a section of circuit, which helps to simplify the circuit layout.

[0049] Even better, the insulating housing 1 has a wire groove 14 at the bottom that connects the first connection hole 12 and each of the second connection holes 13, which makes wiring easier.

[0050] In this embodiment, the electronic indicator is correspondingly arranged with the conductive strip 2. The electronic indicator can be at least one of the following: a warning light 6, an audible and visual alarm, etc. The electronic indicator can be fixed to the insulating housing 1 or arranged in other locations.

[0051] In this embodiment, the insulating housing 1 is installed at the center of the lifting head, and it must be installed horizontally. In the horizontal state, the conductive liquid 3 is located at the center of the concave part 11, and at this time, the initial position of the conductive liquid 3 is equidistant from all points on the conductive strip 2.

[0052] Combination Figure 3This embodiment includes four warning lights 6 of different colors and four conductive strips 2 arranged in a circular array. Each warning light 6 is connected to its corresponding conductive strip 2 through a corresponding conductive path 4. When the equipment experiences a horizontal or dynamic imbalance problem, the conductive liquid 3 connects at least one conductive strip 2 to the conductive path 4, forming at least one closed loop, which illuminates the corresponding indicator light. The direction of deviation can be determined by the color of the warning light 6.

[0053] By visualizing leveling issues, non-level situations can be identified promptly, and the direction of deviation can be accurately determined, reducing the difficulty of adjusting the level and helping to minimize losses caused by leveling problems.

[0054] In addition, such as Figure 4 As shown, this utility model also provides a leveling device, which includes the aforementioned leveling detection device, a switch component 7 and a drive mechanism 8 corresponding to the conductive strip 2. Both the switch component 7 and the drive mechanism 8 are connected to the conductive path 4, and the drive mechanism 8 is connected to the foot of the lifting head. When the circuit containing the switch component 7 is active, the drive mechanism 8 can be a servo motor, which drives the foot screw to extend and retract to achieve lifting adjustment, enabling timely and automatic leveling and further reducing losses caused by leveling issues. In some embodiments, the switch component 7 can be configured as an electromagnetic relay.

[0055] This invention, by setting up a switch component 7 and a drive mechanism 8, can adjust the tilt in a certain direction when the device under test tilts. This is achieved by activating the corresponding circuit switch component 7 and using the drive mechanism 8 to control the extension and retraction of the feet of the device under test. This simplifies the tilt adjustment process and improves the convenience and user experience.

[0056] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
