Description

Technical Field

[0001] This utility model relates to the field of propeller technology, and more specifically, to a submersible propeller mounting structure. Background Technology

[0002] Submersible jet propellers are hydraulically driven devices commonly used in wastewater treatment. Their main function is to propel water forward at a certain velocity, thereby solving the flow problem in the wastewater treatment process, improving wastewater treatment efficiency, and preventing suspended solids from settling.

[0003] Currently, most submersible thrusters are installed underwater using guide rail brackets. The upper end of the guide rail bracket is fixedly connected to the walkway at the top of the sewage tank, and the lower end of the guide rail is fixedly connected to the bottom of the tank using expansion bolts. Because the expansion bolts are soaked in sewage for a long time, they are easily corroded, causing the lower end of the guide rail bracket to loosen. This can easily lead to the guide rail bracket being pulled by the reaction force generated when the submersible thruster is working, causing damage to the guide rail bracket. If the guide rail bracket needs to be replaced, the underwater expansion bolts need to be removed. However, sewage treatment is generally a continuous operation (usually not allowed to be stopped), and the sewage tank is relatively deep, making the removal of the expansion bolts difficult. Therefore, the maintenance of the thruster and its installation structure is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a submersible propeller mounting structure to solve the above-mentioned defects of the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A submersible jet propeller mounting structure includes a mounting bracket, on which the jet propeller is mounted, and further includes:

[0007] The support column is fixedly connected to the lower end of the support bracket. The top of the support column is connected to the walkway. The bottom of the support column is equipped with a base plate, on which several support bolts are connected. The support bolts are pressed against the bottom of the sewage tank.

[0008] A diagonal brace is located behind the flow generator. One end of the diagonal brace is hinged to a column or mounting bracket, and the other end of the diagonal brace is hinged to a support plate, which abuts against the side wall of the sewage tank.

[0009] Optionally, the column or mounting bracket is provided with a first connecting ear, the support plate is provided with a second connecting ear, and the diagonal brace is connected to the first connecting ear and the diagonal brace to the second connecting ear by connecting screws.

[0010] Optionally, the diagonal bracing has two members, which are located at the same height of the column and form a target angle with each other.

[0011] Optionally, the top of the column is hinged to a top plate, which is bolted to the walkway.

[0012] Optionally, the top plate includes a top mounting plate and a top connecting plate. The top connecting plate is rotatably mounted on the top of the column. The top connecting plate and the top mounting plate are connected by several connecting rods. The top mounting plate is bolted to the corridor.

[0013] Optionally, the base plate is a rectangular plate, and the center of the top surface of the base plate is welded to the bottom of the column.

[0014] Optionally, the support screws are provided in four parts, and the four support screws are distributed in a ring array with the column as the center.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the mounting bracket for installing the jet generator is fixedly connected to the lower end of the column. The top of the column is connected to the walkway, and the bottom of the column is supported by several supporting screws pressed against the bottom of the sewage tank. The jet generator is supported at the rear by diagonal bracing rods. That is, the column mainly provides vertical support, and the reaction force generated when the jet generator is working is borne by the diagonal bracing rods, ensuring the stable operation of the jet generator. Compared with the prior art, this utility model avoids the need to drill expansion bolts at the bottom of the sewage tank, so that the maintenance of the jet generator and its mounting structure does not require underwater removal of the expansion bolts, making operation more convenient.

[0020] refer to Figure 1 and Figure 2 A submersible propeller mounting structure includes a mounting bracket 1, a propeller 2 mounted on the mounting bracket 1, and also includes a column 3 and a diagonal brace 6.

[0021] Mounting bracket 1 is fixedly connected (e.g., welded) to the lower end of column 3. The top of column 3 is connected to the walkway (not shown). It should be understood that the walkway (also known as a walkway boardwalk, corridor, etc.) is usually located on the top of the sewage tank for inspection personnel to walk on and for pipeline installation.

[0022] The column 3 has a base plate 4 at its bottom, and several support screws 5 are connected to the base plate 4. The support screws 5 are pressed against the bottom of the sewage tank (not shown in the figure). It is easy to understand that the force generated in the vertical direction when the flow booster 2 is working is very small. This utility model can meet the support requirements by pressing the support screws 5 against the bottom of the sewage tank. As an alternative, in this embodiment, the base plate 4 is a rectangular plate, and the center of the top surface of the base plate 4 is welded to the bottom of the column 3. Further, there are four support screws 5, and the four support screws 5 are distributed in a circular array with the column 3 as the center. For example, one support screw 5 is set at each corner of the base plate 4. Of course, the support screws 5 can also be set at other positions on the base plate 4 (for example, at the middle of each side). In other embodiments, the base plate 4 can of course be other shapes, such as circular.

[0023] The top of column 3 is hinged to a top plate 7. Specifically, the hinge method of top plate 7 is as follows (see reference). Figure 3 The top plate 7 includes a top mounting plate 701 and a top connecting plate 702. The top connecting plate 702 is rotatably mounted on the top of the column 3 (for example, a rotating shaft is provided on the top connecting plate 702, and a hole for the rotating shaft is provided on the top of the column 3). The top connecting plate 702 and the top mounting plate 701 are connected by several connecting rods, and the top mounting plate 701 is bolted to the passageway. It is worth noting that this arrangement allows the top mounting plate 701 to rotate around the rotation center of the top connecting plate 702 before the support screw 5 is pressed against the bottom of the sewage tank, avoiding machining errors that could prevent the column 3 from being in a vertical position and affect the pressing effect of the support screw 5. In other embodiments, the top plate 7 can of course be hinged to the column 3 in other ways.

[0024] The diagonal brace 6 is located behind the flow booster 2. One end of the diagonal brace 6 is hinged to the mounting bracket 1 (or alternatively, to the column 3), and the other end is hinged to a support plate. The support plate abuts against the side wall of the sewage tank and bears the reaction force generated when the flow booster 2 is working. There are two diagonal braces 6, located at the same height as the column 3, and forming a target angle with each other to better bear the reaction force generated when the flow booster 2 is working. The verticality of the target angle is not specifically limited, as long as it ensures stable support. It should be noted that those skilled in the art are capable of determining the specific value of the target angle through a limited number of experiments.

[0025] In this embodiment, the hinge connection between the diagonal brace 6, the support plate, and the mounting bracket 1 is as follows: the mounting bracket 1 is provided with a first connecting lug (easily understood, when the diagonal brace 6 is hinged to the column 3, the first connecting lug is located on the column 3), and the support plate is provided with a second connecting lug. The diagonal brace 6 is connected to the first connecting lug and to the second connecting lug via connecting bolts. It is worth noting that this design allows the diagonal brace 6 to be disassembled, facilitating the replacement of diagonal braces 6 of different lengths according to requirements in practical applications.

[0026] As can be seen from the above, the column 3 in this utility model mainly plays a supporting role in the vertical direction. The reaction force generated when the flow pusher 2 is working is borne by the diagonal brace 6, which ensures the stable operation of the flow pusher 2. Compared with the prior art, it avoids the need to drill expansion bolts at the bottom of the sewage tank, so that the maintenance of the flow pusher 2 and its installation structure does not require the removal of the expansion bolts underwater, making the operation more convenient.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
