Description

Technical Field

[0001] The invention relates to the technical field of rainwater and sewage interception well installation, and more specifically to an unpowered rainwater and sewage interception well installation bracket. Background Art

[0002] Interception wells are used in combined sewer systems to separate rainwater and sewage. In the dry season, there is only sewage in the pipe, so the interception well can intercept the sewage and flow it into the newly built sewage pipe. In the rainy season, part of the rainwater and sewage are intercepted and flow into the sewage pipe, and the rest of the rainwater overflows through the weir in the well and continues to flow downstream.

[0003] The main component of the interception well system is the swirl valve. The existing equipment is installed only by connecting the equipment flange and finalizing it without any support measures. After a large flow of water passes through, the swirl flow is fierce and the external pressure is too large, which will cause the equipment to sag or deform, and in severe cases, it will break. At the same time, in order to adjust the interception flow of the interception well, the swirl valve needs to adjust the installation angle during use. At present, most of the adjustment and installation are carried out manually in the well. The space in the well is limited and the environment is harsh, which brings great difficulties to the adjustment and installation, and also causes harm to the human body. Summary of the invention

[0004] The purpose of the present invention is to provide a non-powered rain and sewage interception well mounting bracket, by which the swirl valve is fixed to increase the firmness of the swirl valve; and the angle of the swirl valve after installation is easy to adjust, and no manual operation is required, so as to solve the technical problems existing in the above-mentioned background technology.

[0005] The technical solution of the present invention is a non-powered rainwater and sewage interception well mounting bracket, comprising a base and a mounting plate fixed to the base by a limiting bracket, the mounting plate being provided with a central fixing hole and two circumferentially arranged arc-shaped limiting grooves located on the outer periphery of the central fixing hole, a flange plate being fixed to the swirl valve away from the water inlet side, the flange plate being fixed to the mounting plate by limiting pieces and a central fixing piece respectively, and the center of the central fixing hole and the center of the water inlet of the swirl valve are on the same axis.

[0006] In a preferred embodiment, the flange is rotatably fixed to the mounting plate, an adjusting mechanism for adjusting the tilt angle of the swirl valve is fixedly connected to the swirl valve, and the adjusting mechanism is fixed to the outside of the intercepting well through an above-the-well bracket.

[0007] In a preferred embodiment, the regulating mechanism includes a reverse wheel fixed on the well support, a rocker arm fixed on the reverse wheel, and a reverse chain sleeved outside the reverse wheel and having both ends fixed to the two sides of the swirl valve.

[0008] In a preferred embodiment, the two ends of the fall chain are fixed to the swirl valve through two lifting ears fixed on both sides of the swirl valve, and the two lifting ears are respectively arranged on adjacent sides of the water inlet of the swirl valve.

[0009] In a preferred embodiment, limiting plates for limiting the motion trajectory of the fall chain are fixed on both sides of the fall wheel.

[0010] In a preferred embodiment, the fixing member includes a center bolt fixed on the flange and with its free end passing through the center fixing hole and fixed to the mounting plate, and the limiting member includes a limiting bolt fixed on the flange and with its free end passing through the arc-shaped limiting groove and fixed to the mounting plate.

[0011] The beneficial effects of the technical solution of the present invention are:

[0012] 1. Using the mounting bracket to fix the swirl valve can effectively solve the problem of unstable fixation caused by vibration, pressure and other factors when the valve is in working state, and ensure the firmness of fixation; by providing the mounting plate, and providing the central fixing hole and the arc-shaped limit groove on the mounting plate, it is convenient to adjust the installation angle of the swirl valve, and the center of the central fixing hole and the center of the water inlet of the swirl valve are on the same axis, ensuring that the position of the water inlet remains unchanged when the angle is adjusted.

[0013] 2. By setting the adjustment mechanism, the installation angle of the swirl valve can be adjusted on the well, without going down the well for adjustment and installation, thus avoiding harm to the human body during operations in a closed and limited space underground and reducing the workload of personnel.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0020] See also Figure 1-4 The technical solution of the present invention is a non-powered rainwater and sewage interception well mounting bracket, comprising a base 4 and a mounting plate 6 fixed on the base 4 by a limiting bracket 5, the mounting plate 6 is provided with a central fixing hole 7 and two circumferentially arranged arc-shaped limiting grooves 8 located on the outer periphery of the central fixing hole 7, a flange 9 is fixed on the swirl valve away from the water inlet side, the flange 9 is fixed to the mounting plate 6 by limiting pieces and a central fixing piece respectively, and the center of the central fixing hole 7 is on the same axis as the center of the water inlet 3 of the swirl valve 2.

[0021] By setting the mounting plate 6, and setting the central fixing hole 7 and the arc-shaped limiting groove 8 on the mounting plate 6, it is convenient to adjust the installation angle of the swirl valve 2. When adjusting the installation angle of the swirl valve 2, loosen the fixing member and the limiting member, and rotate the swirl valve 2 around the central fixing hole 7 by a certain angle. At this time, the limiting member moves along the track defined by the arc-shaped limiting groove 8. The center of the central fixing hole 7 and the center of the water inlet 3 of the swirl valve are on the same axis to ensure that the position of the water inlet 3 remains unchanged when the angle is adjusted. By setting the flange 9 and realizing three-point fixation through a plurality of limiting members and a central hole, the angle adjustment is facilitated while the firmness of the fixation is also ensured.

[0022] The flange 9 is rotationally fixed to the mounting plate 6, that is, under the action of external force, the mounting flange 9 drives the swirl valve 2 to rotate a certain angle around the central fixing hole 7. An adjusting mechanism 13 for adjusting the tilt angle of the swirl valve 2 is fixedly connected to the swirl valve 2, and the adjusting mechanism 13 is fixed to the outside of the intercepting well 1 through the well support 12. By setting the adjusting mechanism 13, the installation angle of the swirl valve 2 can be adjusted on the well, without the need to adjust and install it in the well, avoiding harm to the human body in the closed and limited space operation underground, and reducing the workload of personnel.

[0023] The adjustment mechanism 13 includes a reverse wheel 14 fixed on the well support 12, a rocker arm 15 fixed on the reverse wheel 14, and a reverse chain 16 sleeved outside the reverse wheel 14 and having two ends respectively fixed to the two sides of the swirl valve 2. The reverse wheel 14 is manually shaken to drive the reverse chain 16, thereby driving the swirl valve 2 to rotate a certain angle.

[0024] The two ends of the fall chain 16 are fixed to the swirl valve through two lifting ears 17 fixed on both sides of the swirl valve, and the two lifting ears 17 are respectively arranged on the adjacent sides of the water inlet of the swirl valve. The lifting ears 17 are fixed on the adjacent sides of the water outlet 3 to ensure that the swirl valve 2 rotates around the central fixing hole 7. The two sides of the inverted wheel 14 are fixed with limiting plates 18 for limiting the motion trajectory of the fall chain 16. The limiting plates 18 are used to limit the fall chain 16 to prevent the fall chain 16 from detaching from the inverted wheel 14 during transmission.

[0025] The fixing member includes a central bolt 10 fixed to the flange 9 and having a free end passing through the central fixing hole 7 and fixed to the mounting plate 6, and the limiting member includes a limiting bolt 11 fixed to the flange 9 and having a free end passing through the arc-shaped limiting groove 8 and fixed to the mounting plate 6. Fixing by the central bolt 10 and the limiting bolt 11 facilitates adjustment of the tightness of the fixation, ensuring that the flange 9 can rotate when the adjusting mechanism 13 is adjusted.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
