Detailed Description

In order to make the present utility model better understood by those skilled in the art, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1, a level verification device 100 includes a bracket 11 and a level 12, the bracket 11 constituting a basic frame of the level verification device 100. The level 12 is provided on the support 11 as a reference object for judging whether the furnace body is horizontal. For clarity of description of the technical solution of the present utility model, the front side, the rear side, the left side, the right side, the upper side and the lower side are also defined as shown in fig. 1.

As an embodiment, as shown in fig. 2, specifically, the bracket 11 includes a first bracket portion 111 extending in the first direction 101 and a second bracket portion 112 extending in the second direction 102, and the first bracket portion 111 and the second bracket portion 112 intersect with each other. The level 12 is provided at both ends of the first and second bracket parts 111 and 112 of the bracket 11. The structure of the support 11 with the support parts arranged in two directions gives the level 12 more arrangement space, so that the level conditions of different directions of the furnace body can be measured simultaneously, and the measurement range and the measurement efficiency of the level verification device 100 are increased. With the above arrangement, the water column position of each level 12 can be observed to determine whether the furnace is level. In addition, according to the theorem that the moment arm is larger and the moment generated is larger as the balance point is far away, the water column on the level 12 can be displayed to the greatest extent by arranging the level 12 at the two ends of the first bracket part 111 and the second bracket part 112 of the bracket 11, so that the accuracy of the measurement result is high, and the level condition of the furnace body is more favorable for a measurer to observe visually.

As an embodiment, as shown in fig. 2, the level 12 includes a bar-type level 121, and the bar-type level 121 is provided at both ends of the first bracket portion 111 and both ends of the second bracket portion 112. Specifically, the bar type level 121 provided on the first bracket portion 111 extends in the first direction 101, and the bar type level 121 provided on the second bracket portion 112 extends in the second direction 102. When the two ends of the furnace body plane have the height, the bubbles in each strip level 121 always move to the highest side of the strip level 121 due to the gravity. By the above-described structural arrangement of the bar-type level 121 in the direction, the bar-type level 121 extending in the first direction 101 is made parallel to the first bracket portion 111, and the bar-type level 121 extending in the second direction 102 is made parallel to the second bracket portion 112. Therefore, a measurer can more intuitively observe whether the furnace body is inclined and the degree and direction of the inclination, and the deviation of the position of the strip level 121 is reduced to bring errors to the movement degree of bubbles in the strip level, so that the overall accuracy and measurement efficiency are improved.

As an embodiment, an angle α exists between the first direction 101 and the second direction 102, and in particular, the angle α may be understood as an angle between the first bracket portion 111 and the second bracket portion 112. More specifically, the angle α between the first direction 101 and the second direction 102 is 60 ° or more and 120 ° or less. By setting the angle as described above, the direction and range in which the horizontal checking device 100 can measure can be increased. This arrangement allows the level 12 to more standard reflect the level of the furnace in all directions while satisfying the measurement of the furnace. Further, the included angle α between the first direction 101 and the second direction 102 is 85 ° or more and 95 ° or less.

As an embodiment, as shown in fig. 2, the level 12 is further provided at the intersection of the first bracket portion 111 and the second bracket portion 112, and is vertically mounted on the bracket 11 along the up-down direction of the level verification device 100. By the above arrangement, the level 12 is positioned at the center of the level verification device 100, so that the overall level of the center of gravity of the level verification device 100 can be reflected quickly. In the actual measurement process, a measurer firstly observes the measurement result of the level meter 12 and timely adjusts the position of the furnace body, and then further calibrates the furnace body according to the observed conditions of each level meter 121, thereby improving the measurement work efficiency.

As an embodiment, as shown in fig. 3 and 4, the level 12 further includes a disk level 122, and the surface of the disk level 122 is circular. The circular disc level 122 can give measurement instructions in all directions, and when the water column in the disc level 122 changes, a measurer can accurately position the inclined angle and position through the circular surface and immediately adjust the inclined angle and position, so that the measuring work efficiency is improved. More specifically, the bracket 11 is provided with a mounting portion 13 at the intersection of the first bracket portion 111 and the second bracket portion 112, the disc level 122 is provided in the mounting portion 13 and the upper surface of the disc level 122 coincides with the upper surface of the bracket 11 so that the upper and lower surfaces of the level verification device 100 are entirely parallel. Through the arrangement, the horizontal checking device 100 and the furnace bottom can be embedded and connected, and the surface of the horizontal checking device and the furnace body are on the same plane, so that the measurement is ensured to be quick and accurate, and the working efficiency is improved. In addition, this arrangement improves the compactness of the disc level 122, further improving the overall space utilization of the level 100, and making the level 100 more portable and flexible. It can be appreciated that the horizontal calibration device 100 can independently complete the horizontal calibration function of the furnace body by providing the strip type level 121, so that the structure of the horizontal calibration device 100 is simplified. The horizontal calibration device 100 may also be provided with a combination of the strip level 121 and the disc level 122, so that the horizontal condition of the furnace body can be determined by observing each level 12 more quickly, and errors possibly caused by the horizontal calibration device 100 can be eliminated to a certain extent, so that the measurement result is more accurate.

As an embodiment, as shown in fig. 5, the mounting portion 13 is a circular mounting portion. The mounting portion 13 is concentric with the surface of the disk level 122, and the disk level 122 is provided in the mounting portion 13 in the up-down direction of the level verification device 100. By the above-mentioned concentric circle structure, the disc level 122 and the mounting portion 13 can be more tightly attached to ensure that the disc level 122 is unnecessarily loosened to cause the level checking device 100 to incline to affect the measurement result. In the present embodiment, the diameter Φ of the mounting portion 13 is 165mm or more and 255mm or less. Further, the diameter phi of the mounting portion 13 is 190mm or more and 230mm or less. Further, the diameter phi of the mounting portion 13 is 200mm or more and 220mm or less.

As an embodiment, as shown in fig. 5, a length L1 of the first holder portion 111 in the first direction 101 is 640mm or more and 960mm or less, and a length L2 of the second holder portion 112 in the second direction 102 is 640mm or more and 960mm or less. Through the length setting, the horizontal verification device 100 can be basically matched with the whole measured furnace body size, so that the horizontal verification device 100 can be ensured to cover the surface of the furnace body to the greatest extent, and the whole horizontal condition of the furnace body in the first direction 101 and the second direction 102 can be measured rapidly. In addition, this arrangement can make the volumes of the first bracket portion 111 and the second bracket portion 112 in the extending direction thereof not differ much, thereby ensuring that the center of gravity of the horizontal calibration device 100 can be at a position closer to the center, and further enabling the horizontal calibration device 100 to quickly balance itself for measurement of the furnace body, thereby improving the working efficiency. Further, a length L1 of the first holder portion 111 in the first direction 101 is 720mm or more and 880mm or less, and a length L2 of the second holder portion 112 in the second direction 102 is 720mm or more and 880mm or less. Further, a length L1 of the first stand portion 111 in the first direction 101 is 760mm or more and 840mm or less, and a length L2 of the second stand portion 112 in the second direction 102 is 760mm or more and 840mm or less.

In the present embodiment, as shown in fig. 3, the height H of the stand 11 is 48mm or more and 72mm or less, and the height H of the stand 11 is the length of the perpendicular line between the upper surface and the lower surface of the stand 11. Through the arrangement, on the premise that the level 12 is ensured to have enough arrangement space on the bracket 11, the whole gravity center of the horizontal checking device 100 can be closer to the plane of the furnace body, so that the stability of the whole connection of the horizontal checking device 100 and the furnace body is improved. In addition, the horizontal calibration device 100 is embedded at the bottom of the furnace body during measurement, and the arrangement can reduce the space occupation rate of the horizontal calibration device 100, so that more operation space is provided for a user. Further, the height H of the stand 11 is 54mm or more and 66mm or less. Further, the height H of the stand 11 is 57mm or more and 63mm or less.

According to the embodiment, through the interconnection and the cooperation of the bracket 11 and the level meter 12, a measurer can rapidly judge whether the horizontal plane of the furnace body is inclined or not by observing the change of the level meter 12 on the bracket 11, so that the subsequent crystal growth work can be conveniently unfolded, and the production work efficiency is improved.
