[0036] Overflow weirs are commonly used in water treatment, such as the treatment of sewage. Generally, they are arranged in water treatment structures such as sedimentation tanks and are important devices for overflow water collection. When the water surface is higher than the top of the overflow weir, the water flows over the top and flows into subsequent water treatment structures, such as treatment ponds or collection ponds in subsequent processes, to achieve water collection and transportation.

[0037] The overflow weir plays a role in blocking the water flow and can block most impurities, such as sludge and suspended solids. The water flow passing through the overflow weir is relatively clean, achieving the purpose of preliminary water purification.

[0038] By adjusting the height of the overflow weir, the water level in structures such as sedimentation tanks can be controlled to ensure the normal operation of the water treatment process.

[0039] However, the existing overflow weirs cannot be quickly and conveniently adjusted in length, nor can their installation height be adjusted.

[0040] Refer to Figure 1 and Figure 2 As shown in

[0041] The first weir plate assembly 110 has a hollow interior. On the plate surface of the first weir plate assembly 110, there is a first adjustment groove 111 penetrating the plate surface. The first adjustment groove 111 extends along the length direction of the first weir plate assembly 110. On the plate surface of the first weir plate assembly 110, there are also a plurality of second adjustment grooves 112 penetrating the plate surface. The plurality of second adjustment grooves 112 are spaced apart along the length direction of the first adjustment groove 111, and the second adjustment grooves 112 are perpendicular to the first adjustment groove 111;

[0042] The second weir plate assembly 120 is inserted into the first weir plate assembly 110. A third adjustment groove 121 penetrating the plate surface is provided on the plate surface of the second weir plate assembly 120. The third adjustment groove 121 extends along the length direction of the second weir plate assembly 120. A plurality of fourth adjustment grooves 122 penetrating the plate surface are further provided on the plate surface of the second weir plate assembly 120. The plurality of fourth adjustment grooves 122 are spaced apart along the length direction of the third adjustment groove 121. The fourth adjustment grooves 122 are perpendicular to the third adjustment groove 121.

[0043] After the second weir plate assembly 120 is inserted into the first weir plate assembly 110, the third adjustment groove 121 and the first adjustment groove 111 can coincide, that is, the overlapping part of the first adjustment groove 111 and the third adjustment groove 121 completely penetrates through the water weir, and can supply the connecting assembly 200 to pass through and fix the first weir plate assembly 110 and the second weir plate assembly 120. The change in the relative position of the first weir plate assembly 110 and the second weir plate assembly 120 can quickly and conveniently adjust the length of the water weir.

[0044] When pulling the second weir plate assembly 120 to generate a relative displacement with the first weir plate assembly 110, the displacement amount of the two can be controlled so that the second adjustment groove 112 and the fourth adjustment groove 122 can also remain coincident.

[0045] Taking the first adjustment groove 111 and the second adjustment groove 112 as an example, the first adjustment groove 111 extends along the length direction of the first weir plate assembly 110, and the second adjustment groove 112 is perpendicular to the first adjustment groove 111. Therefore, when the first weir plate assembly 110 moves along the direction of the second adjustment groove 112, the installation height of the first weir plate assembly 110 can be changed. When the first weir plate assembly 110 and the second weir plate assembly 120 move integrally along the direction of the second adjustment groove 112 or the fourth adjustment groove 122, the installation height of the water weir can be changed, realizing the rapid adjustment of the installation height of the water weir.

[0046] A plurality of connecting assemblies 200 all pass through the first adjustment groove 111 and the third adjustment groove 121 to fix the first weir plate assembly 110 and the second weir plate assembly 120. The plurality of connecting assemblies 200 are spaced apart along the length direction of the first adjustment groove 111.

[0047] Generally, the connecting assembly 200 passes through the first adjustment groove 111 and the third adjustment groove 121, and then approaches the central plane of the first weir plate assembly 110, and can clamp the first weir plate assembly 110 and the second weir plate assembly 120.

[0048] When the height of the water overflow weir needs to be adjusted, the connecting component 200 can move into the second adjustment groove 112 and the fourth adjustment groove 122. In some embodiments, the water overflow weir is fixed on the side wall of the pool body, and the relative position between the connecting component 200 and the side wall of the pool body remains unchanged. By moving the water overflow weir to make the connecting component 200 move in the second adjustment groove 112 or the fourth adjustment groove 122, the height of the water overflow weir can be changed.

[0049] It should be understood that the second adjustment groove 112 and the fourth adjustment groove 122 can overlap, so that the connecting component 200 can penetrate through the second adjustment groove 112 and the fourth adjustment groove 122. Since there are multiple second adjustment grooves 112, which are distributed along the length direction of the first adjustment groove 111; there are also multiple fourth adjustment grooves 122, which are distributed along the length direction of the third adjustment groove 121, so pulling the second weir plate assembly 120 along the length direction of the first adjustment groove 111 or the third adjustment groove 121 can adjust at least the overlap of the second adjustment groove 112 and the fourth adjustment groove 122.

[0050] It can be understood that the cross-section of the first weir plate assembly 110 is a rectangular frame, and the inner side of the rectangular frame is a cavity. The cross-section of the second weir plate assembly 120 is a rectangular solid, and the outer contour of the cross-section of the second weir plate assembly 120 matches the inner contour of the cross-section of the first weir plate assembly 110.

[0051] The solid second weir plate assembly 120 can improve the structural strength of the water overflow weir in the first weir plate assembly 110. Even if the length of the water overflow weir needs to be adjusted and a part of the second weir plate assembly 120 is pulled out of the first weir plate assembly 110, the main structure of the water overflow weir is still the overlapping structure of the first weir plate assembly 110 and the second weir plate assembly 120, which is the main part affected by the water flow impact force. On both sides of the water overflow weir, the impact force of the water flow is small, so there is only the second weir plate assembly 120 or the first weir plate assembly 110, and it is not easy to be damaged by the water flow.

[0052] In some embodiments, the water overflow weir is designed modularly, that is, the lengths of both the first weir plate assembly 110 and the second weir plate assembly 120 are 1m, or other values, which can be adjusted according to the situation. The displacement between the first weir plate assembly 110 and the second weir plate assembly 120 is preferably controlled between 0 and 200mm, that is, the maximum pulling-out length of the second weir plate assembly 120 is 200mm.

[0053] In some embodiments, the groove widths of the first adjustment groove 111 and the third adjustment groove 121 are set to 10mm, and the groove widths of the second adjustment groove 112 and the fourth adjustment groove 122 can also be set to 10mm. At the same time, the lengths of the second adjustment groove 112 and the fourth adjustment groove 122 are preferably set to 50mm. Of course, the lengths of the second adjustment groove 112 and the fourth adjustment groove 122 can also be set to the required lengths according to needs.

[0054] It can be understood that the connecting component 200 includes bolts, nuts and two gaskets. The bolts pass through the first weir plate component 110 and the second weir plate component 120. The gaskets are sleeved on the bolts. One gasket abuts against the first weir plate component 110, and the other gasket abuts against the second weir plate component 120. The outer diameter of the gasket is greater than the groove width of the first adjustment groove 111 and the second adjustment groove 112. The nut is sleeved on the bolt and locks the first weir plate component 110 and the second weir plate component 120.

[0055] The size of the bolts should be smaller than the first adjustment groove 111, the second adjustment groove 112, the third adjustment groove 121 and the fourth adjustment groove 122, so as to facilitate the bolts to pass through the first weir plate component 110 and the second weir plate component 120 and be locked by nuts. It should be understood that the gaskets are pre-threaded on the bolts, and the two gaskets are respectively located on both sides of the first weir plate component 110. The size of the gasket is greater than the groove width of the first adjustment groove 111 and the second adjustment groove 112. Therefore, the gasket can closely adhere to the first weir plate component 110 and clamp and fix the first weir plate component 110 and the second weir plate component 120.

[0056] Refer to Figure 3 As shown, the overflow structure of the pool body in an embodiment of the present invention includes a pool body side wall 300, a plurality of mounting components 400 and the above-mentioned water passing weir 100. The water passing weir 100 is arranged on the upper part of the pool body side wall 300, and the water passing weir 100 is connected to the pool body side wall 300 through a plurality of mounting components 400.

[0057] The water passing weir 100 is generally arranged on the upper part of the pool body side wall 300 to achieve the effect of intercepting suspended matter during water flow overflow. In some embodiments, the mounting component 400 can directly utilize the connecting component 200, that is, the bolts of the connecting component 200 are directly screwed into the threaded holes of the pool body side wall 300, so that not only the first weir plate component 110 and the second weir plate component 120 can be fixed, but also they can be fixed on the pool body side wall 300.

[0058] Refer to Figure 4 Or Figure 5 As shown, it can be understood that in some other embodiments, the mounting component 400 includes a base 410 and a support rod 420. The base 410 is fixed to the pool body side wall 300. One end of the water passing weir 100 is rotatably connected to the base 410. The base 410 is provided with a guide groove 411. The guide groove 411 is parallel to the rotation plane of the water passing weir 100. One end of the support rod 420 is arranged in the guide groove 411 and can move along the guide groove 411. The other end of the support rod 420 is rotatably connected to the water passing weir 100.

[0059] When the support rod 420 moves along the guide groove 411, it can push the water overflow weir 100 to rotate so as to change the installation angle of the water overflow weir 100. It should be understood that changing the installation angle of the water overflow weir 100 can also adjust the equivalent height of the water overflow weir 100, thereby changing the water level height in the pool.

[0060] It should be understood that the damping between the support rod 420 and the guide groove 411 can be obtained by means of frictional connection, which can not only move the support rod 420 to change the angle of the water overflow weir 100, but also keep the position of the support rod 420 unchanged through the damping, so as to keep the angle of the water overflow weir 100 unchanged.

[0061] Refer to Figure 4 As shown, it can be understood that a support plate 430 is provided between the support rod 420 and the water overflow weir 100. The support plate 430 is attached to the plate surface of the water overflow weir 100, and a hinge structure is provided on the plate surface of the support plate 430. The support rod 420 is connected to the support plate 430 through the hinge structure.

[0062] Generally speaking, the rotational connection between the support rod 420 and the water overflow weir 100 adopts the hinge method. If a hinge structure is provided on the water overflow weir 100, it is not conducive to the production and manufacture of the water overflow weir 100. And when the length of the water overflow weir 100 is adjusted, the relative position between the hinge structure on the water overflow weir 100 and the side wall 300 of the pool will change, that is to say, the base 410 also needs to be adjusted synchronously.

[0063] Setting the hinge structure connected to the support rod 420 on the support plate 430 can well solve the above problems. Specifically, the support plate 430 can be bolted to the water overflow weir 100. It is convenient to disassemble between the support plate 430 and the water overflow weir 100, and the first adjustment groove 111, the second adjustment groove 112, the third adjustment groove 121 and the fourth adjustment groove 122 of the water overflow weir 100 can be directly used for bolt connection with the support plate 430.

[0064] It can be understood that a slag baffle assembly 500 is further provided on the side wall 300 of the pool. The slag baffle assembly 500 is located above the water overflow weir 100, and a water flow channel is formed between the slag baffle assembly 500 and the water overflow weir 100.

[0065] The slag baffle assembly 500 can improve the uniformity when the water flows out. Even if the water volume increases within a certain range, the water flow channel between the slag baffle assembly 500 and the water overflow weir 100 remains constant, so as to limit the size of the water flow out, that is, to keep the uniformity when the water flows out.

[0066] Refer to Figure 6As shown, it can be understood that in some embodiments, the slag baffle assembly 500 includes a plurality of first fixing columns 510, a first inclined plate 520, and a second inclined plate 530. The plurality of first fixing columns 510 are distributed along the length direction of the overflow weir 100. The first fixing columns 510 are vertically arranged and fixed to the overflow weir 100. The length direction of the first inclined plate 520 is parallel to the length direction of the overflow weir 100, and the length direction of the second inclined plate 530 is also parallel to the length direction of the overflow weir 100. The first inclined plate 520 and the second inclined plate 530 are both fixed to the first fixing columns 510, and the first inclined plate 520 and the second inclined plate 530 are symmetrically distributed about the first fixing columns 510 to form a herringbone shape. The long sides of the first inclined plate 520 and the second inclined plate 530 both extend below the upper end surface of the overflow weir 100.

[0067] The water flow and suspended matter first come into contact with the first inclined plate 520 or the second inclined plate 530 and contact one of them according to the water flow direction. Refer to Figure 3 As shown, for example, when the water flow enters from right to left, the water flow first comes into contact with the second inclined plate 530. The water flow slows down its velocity during the rising process along the second inclined plate 530, promoting the sedimentation of suspended matter, so as to more effectively perform solid-liquid separation, and is suitable for sewage treatment facilities that require efficient solid-liquid separation.

[0068] In some embodiments, the first fixing columns 510 are distributed along the length direction of the overflow weir 100, and the spacing distance between two adjacent first fixing columns 510 is maintained at 0.5 m.

[0069] It can be understood that a plurality of reinforcing plates 540 are also provided on the first inclined plate 520 and the second inclined plate 530. One side of the reinforcing plate 540 is connected to the first inclined plate 520 or the second inclined plate 530, and the other side of the reinforcing plate 540 is connected to the first fixing columns 510.

[0070] The reinforcing plate 540 is used to improve the structural strength of the slag baffle assembly 500 and can also play a role in adjusting the water flow channel.

[0071] Refer to Figure 7 As shown, it can be understood that in other embodiments, the slag baffle assembly 500 includes a plurality of second fixing columns 550, a horizontal plate 560, and a vertical plate 570. The plurality of second fixing columns 550 are distributed along the length direction of the overflow weir 100. The second fixing columns 550 are vertically arranged and fixed to the overflow weir 100. The length direction of the horizontal plate 560 is parallel to the length direction of the overflow weir 100, and the length direction of the vertical plate 570 is parallel to the length direction of the overflow weir 100. The horizontal plate 560 is horizontally arranged and fixed to the second fixing columns 550, and the vertical plate 570 is vertically arranged and fixed to the horizontal plate 560. The lower side of the vertical plate 570 extends below the upper end surface of the overflow weir 100.

[0072] The horizontal plate 560 is used to form a water flow channel with the overflow weir 100. The vertical plate 570 extends below the upper end surface of the overflow weir 100, so that the water flow needs to turn back downward before entering the water flow channel and overflowing. Thus, the suspended matter is blocked by the vertical plate 570. The vertical plate 570 can adjust the water flow resistance, prevent the water flow from directly impacting the overflow weir 100, reduce the disturbance of the water flow to the activated sludge, thereby maintaining the stability of the sludge layer, improving the sewage treatment efficiency, and being applicable to the treatment occasions that require fine adjustment of the water flow direction.

[0073] Referring to Figure 8 As shown, in some embodiments, fixing plates may be provided at both ends of the overflow weir 100 in the length direction. The fixing plate 600 is triangular. One side of the fixing plate 600 is connected to the side wall 300 of the pool body, and the other side is connected to the overflow weir 100, playing a role in stably supporting the overflow weir 100.

[0074] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
