Description

Technical Field

[0001] This utility model relates to the field of meteorological Stevenson screen column technology, and in particular to a Stevenson screen column with a built-in hollow tube. Background Technology

[0002] Stevenson screens are specialized equipment used in meteorological observations to house meteorological instruments such as temperature and humidity meters. They are typically supported and fixed at a suitable height by columns to ensure the accuracy of the observation data. However, the following problems still exist in actual operation: Due to concentrated stress and a lack of effective buffering and adaptable structures at the connection points between the existing Stevenson screen columns and the top and bottom plates, long-term use can easily lead to loose connections and wear, affecting the column's support stability and potentially causing the Stevenson screen to tilt, thus affecting the normal operation of meteorological instruments and the reliability of observation data. Furthermore, the existing column connection structure is fixed to the ground with bolts, resulting in insufficient grip (i.e., insufficient connection strength). Especially in windy or soft soil environments, the stability and safety of the column cannot be effectively guaranteed, potentially causing the column and the weather Stevenson screen to tip over. Summary of the Invention

[0003] The purpose of this utility model is to provide a louvered box column with a built-in hollow tube to solve the problems mentioned in the background art, such as the unstable connection of traditional louvered box columns, which are prone to loosening, poor connection stability, and unreliable grip on the ground.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A louvered box column with a built-in hollow tube includes a base plate, a top plate, a hollow tube, and a column. The base plate is fixedly connected to the top plate through the column. The top plate has an upper opening, and the base plate has a lower opening. The hollow tube is provided on the inner wall of the upper and lower openings.

[0005] Preferably, an upper pad is provided between the top plate and the column, and a lower pad is provided between the bottom plate and the column.

[0006] Preferably, the column is shaped like a "slender waist". The top of the column has an upper receiving groove that accommodates the upper pad, and the bottom of the column has a lower receiving groove that accommodates the lower pad. The bottom end of the column also has several connecting grooves arranged in a ring at equal intervals. The upper receiving groove has several upper connecting holes arranged in a rectangular array, and the lower receiving groove has lower connecting holes that connect to the connecting grooves.

[0007] Preferably, the column is composed of two symmetrically arranged left and right semicircular columns joined together by several bolts.

[0008] Preferably, the upper pad is composed of an upper main pad and several upper auxiliary pads bonded together, with the several upper auxiliary pads corresponding to the positions of several upper connecting holes.

[0009] Preferably, the lower pad is composed of several lower main pads and several lower auxiliary pads bonded together, with the lower main pads and lower auxiliary pads arranged in a ring-shaped interval, and the lower auxiliary pads corresponding to the positions of several lower connecting holes.

[0010] Compared with the prior art, the louvered box column with built-in hollow tube provided by this utility model has the following beneficial effects: This utility model has a simple and reasonable structure and is suitable for soft soil. The hollow tube is located inside the column and can be driven into the soft soil by piling. At the same time, it can be firmly connected to the louvered box, which improves the stability of the connection between the column and the ground and the connection with the louvered box. It can effectively prevent the column and louvered box from tipping over in environments with strong winds or soft soil.

[0011] In addition, the upper and lower pads of this utility model can prevent the connection from loosening and wear caused by long-term shaking between the top plate and the bottom plate and the column, further improving the connection stability between the column and the top and bottom plates, thereby further improving the connection stability between the column and the louver box and the ground.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A louvered box column 4 with a built-in hollow tube 3 includes a base plate 2, a top plate 1, a hollow tube 3 and a column 4. The base plate 2 is fixedly connected to the top plate 1 through the column 4. The top plate 1 has an upper opening 11 and the base plate 2 has a lower opening 21. The hollow tube 3 is welded and fixed to the inner wall of the upper opening 11 and the lower opening 21. The hollow tube 3 can be made of stainless steel, which has good corrosion resistance and rigid support capacity.

[0017] An upper pad 5 is provided between the top plate 1 and the column 4, and a lower pad 6 is provided between the bottom plate 2 and the column 4. Both the upper pad 5 and the lower pad 6 are made of hard rubber, which has good cushioning performance and can play a buffering and adaptation role between the top plate 1 and the column 4, and between the bottom plate 2 and the column 4, reducing wear and loosening of the connection parts and improving the stability of the connection.

[0018] Column 4 has a "slender waist" shape. The design of this shape is aesthetically pleasing while ensuring the supporting strength of the column 4, reducing its overall weight, saving material costs, and providing good wind resistance. The top of the column 4 has an upper receiving groove 41 for housing the upper pad 5, and the bottom of the column 4 has a lower receiving groove 42 for housing the lower pad 6. The upper and lower receiving grooves 41 and 42 allow for precise positioning and installation of the upper and lower pads 5 and 6, preventing displacement during use. The bottom of the column 4 has three annularly spaced connecting grooves 43, which provide a more stable connection with the base plate 2. The upper receiving groove 41 has four upper connecting holes 411 arranged in a rectangular array, and the three lower receiving grooves 42 each have three lower connecting holes 421 that connect to the connecting grooves 43. The upper and lower connecting holes 411 and 421 are used to securely connect the column 4 to the upper pad 5, lower pad 6, top plate 1, and base plate 2.

[0019] Please see Figure 3The column 4 is composed of two symmetrically arranged left semicircular columns 401 and right semicircular columns 402, which are spliced ​​together by 10 bolts. The splicing surfaces of the left semicircular columns 401 and right semicircular columns 402 are provided with threaded holes that are compatible with the bolts. The splicing structure allows the left semicircular column 401 and right semicircular column 402 to be separated simply by removing the bolts when the column needs to be disassembled, maintained or replaced. The operation is simple and quick, which greatly improves the maintenance efficiency. Please see Figures 2-4 The upper pad 5 consists of one upper main pad 51 and four upper auxiliary pads 52 glued together. The four upper auxiliary pads 52 are arranged in a rectangular array at the four corners of the upper pad 5, and each of the four upper auxiliary pads 52 corresponds to the position of the four upper connecting holes 411. The upper main pad 51 acts as a buffer for the connection between the top plate 1 and the column 4, while the upper auxiliary pads 52 provide elastic fastening for the bolt connection. This combined upper pad 5 design can be precisely adapted to the position of the upper connecting holes 411 to ensure the reliability of the connection. At the same time, when one of the upper auxiliary pads 52 is worn, only the corresponding upper auxiliary pad 52 needs to be replaced, without replacing the entire upper pad 5, thus reducing maintenance costs.

[0020] The lower pad 6 is composed of three lower main pads 61 and three lower auxiliary pads 62 glued together. The three lower main pads 61 and three lower auxiliary pads 62 are arranged in a ring with intervals between them. The three lower auxiliary pads 62 correspond to the positions of the three lower connecting holes 421. Similarly, the lower main pads 61 provide a buffer for the connection between the base plate 2 and the column 4, while the lower auxiliary pads 62 provide elastic fastening for the bolt connections. The corresponding arrangement of the lower auxiliary pads 62 and the lower connecting holes 421 ensures the accuracy and stability of the connection between the column 4 and the base plate 2. When a lower auxiliary pad 62 is worn, only the corresponding lower auxiliary pad 62 needs to be replaced, without replacing the entire lower pad 6, thus reducing maintenance costs. Furthermore, the spaced lower main pads 61 and lower auxiliary pads 62 further enhance the buffering performance and load-bearing capacity of the lower pad 6.

[0021] It should be noted that both the upper connecting hole 411 and the lower connecting hole 421 are threaded holes, which can be connected to the top plate 1 and the bottom plate 2 by bolts. The top plate 1 and the upper auxiliary washer 52 both have openings corresponding to the upper connecting holes, and the bottom plate 2 and the lower auxiliary washer 62 both have openings corresponding to the lower connecting holes 421, so that bolts can be used to fasten the top plate 1 and the column together through the upper connecting hole 411, and to fasten the bottom plate 2 and the column together.

[0022] The installation process in this embodiment is as follows: First, the hollow tube 3 is driven into the ground, and the driving depth is determined according to the geological grade of the local loose soil. Then, the left semi-circular column 401 and the right semi-circular column 402 are spliced ​​and fixed with bolts. Next, the upper pad 5 is placed in the upper receiving groove 41 at the top of the column 4, so that the upper auxiliary pad 52 is aligned with the upper connecting hole 411. Then, the top plate 1 is placed on the upper pad 5, and the top plate 1 is fixedly connected to the column 4 by bolts passing through the top plate 1 and the upper connecting hole 411. Next, the lower pad 6 is placed in the lower receiving groove 42 at the bottom of the column 4, so that the lower auxiliary pad 62 is aligned with the lower connecting hole 421. Then, the bottom plate 2 is fixedly connected to the column 4 by bolts through the lower connecting hole 421 of the connecting groove 43. Finally, the connected top plate 1, bottom plate 2 and column 4 are fitted into the hollow tube 3 through the upper opening 11 and the lower opening 21, so that it is interference fit with the outer wall of the hollow tube 3, thus completing the installation of the entire device.

[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
