Description

Technical Field

[0001] This utility model relates to a positioning template for on-site drilling of the side wall of a water collection tank, belonging to the field of tooling and fixture technology. Background Technology

[0002] A water collection trough is a device used to evenly collect overflow water. It is mainly installed at the outlet end of a sedimentation tank and often adopts a strip-hole type or a sawtooth weir type structure. The strip-hole type water collection trough is suitable for small-flow overflow, while the sawtooth weir type water collection trough is suitable for large-flow overflow. When the influent flow rate or the operating parameters of the treatment tank change, the traditional structure with fixed orifice or fixed weir height is difficult to adjust the overflow load synchronously, which can easily cause short-circuiting or carry-over of scum.

[0003] For new projects, there are existing modular water collection tanks with adjustable weir height available. However, for existing, non-adjustable tanks that have already been installed, if overflow adjustment is required, either the tank must be replaced with a new product with adjustable weir height, or an adjustable weir plate must be added to the existing water collection tank. Considering all factors, making the tank adjustable is the more economical option.

[0004] Adjustable modification of existing troughs requires drilling holes in the original structure. Drilling requires precision, and the traditional method of drawing positioning lines results in poor positioning accuracy, which affects the installation of adjustable weir plates. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model proposes a positioning template for on-site drilling of the sidewall of a water collection tank. This template ensures the accuracy of drilling on the sidewall of the water collection tank and improves the efficiency of adjustable modification of the overflow structure of the water collection tank.

[0006] This utility model relates to a positioning template for on-site drilling of the side wall of a water collection tank, comprising: a template body, a side flange, and a connecting plate;

[0007] The side flanges are set on both sides of the template body and are used to abut against the two sides of the weir plate on the side wall of the water collection tank. The two side flanges are fixedly connected by connecting plates. The connecting plates are parallel to the template body and are equipped with clamping bolts. The clamping bolts are used to press the side wall of the water collection tank against the template body.

[0008] The template body is provided with drilling points.

[0009] Compared with the prior art, the present invention has the following technical effects:

[0010] The drilling positioning is completed in one clamping, which helps to ensure the accuracy of batch drilling, whether drilling with a hand-held electric drill or with the help of a guide tool. It solves the problems of high drilling difficulty and poor drilling accuracy when there is a lack of safe and suitable construction conditions on site. Attached Figure Description

[0015] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] It should be noted that, in specific embodiments, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly defined, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment relates to a positioning template 10 for on-site drilling of the side wall 20 of the water collection tank. The positioning template 10 is used to be fitted onto the weir plate of the side wall 20 of the water collection tank.

[0018] The positioning template 10 is provided with drilling points 12, and the size of the drilling points 12 is determined according to the installation requirements of the adjustable weir plate to be installed.

[0019] The positioning template 10 is provided with a template body 11, side flanges 14 and connecting plates 15. The side flanges 14 are located on both sides of the template body 11, forming a 90° angle. The side flanges 14 are used to abut against the side of the weir plate on the side wall 20 of the water collection tank. The two side flanges 14 are fixedly connected to the connecting plates 15. The connecting plates 15 are parallel to the template body 11. The connecting plates 15 are provided with clamping bolts 30. The clamping bolts 30 are used to press the template body 11 against the side wall 20 of the water collection tank to prevent the positioning template 10 from tilting up and down and affecting the drilling accuracy.

[0020] In some preferred embodiments, the side flange 14 is integrally formed with the template body 11, and the connection between the two is rounded and chamfered on the inner side. An inner support plate 16 is fixed on the template body 11 near the clamping bolt 30. The length of the inner support plate 16 (in the AA direction) is less than the distance between the two side flanges 14. By using the inner support plate 16, the water collection tank side wall 20 and the template body 11 are indirectly pressed together without gaps, further avoiding the vertical tilt of the positioning template 10 from affecting the drilling accuracy.

[0021] More preferably, the top of the template body 11 is also provided with an upper flange 13, which forms a 90° angle with the template body 11, so that the positioning template 10 can be hung on the side wall 20 of the water collection tank, making it convenient to operate the clamping bolts 30. Furthermore, the length of the upper flange 13 (in the AA direction) is less than the distance between the two flanges 14, that is, less than the length of the weir plate on the side wall 20 of the water collection tank (in the AA direction), making it convenient to observe from above.

[0022] In some preferred embodiments, the positioning template 10 may be made of plastic or metal.

[0023] The upper flange 13, side flange 14, connecting plate 15, inner support plate 16 and template body 11 of the positioning template 10 made of plastic material are integrally formed by injection molding process.

[0024] The metal positioning template 10 has an upper flange 13 and a side flange 14 integrally formed with the template body 11 through sheet metal processing. The inner support plate 16 is welded to the template body 11, and the connecting plate 15 is welded to the side flange 14.

[0025] The positioning template 10 of this utility model completes the drilling positioning in one clamping. Whether drilling with a hand-held electric drill or with the help of a guide tool, it helps to ensure the accuracy of batch drilling and solves the problems of high drilling difficulty and poor drilling accuracy when there is a lack of safe and suitable construction conditions on site.

[0026] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
