Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and in particular relates to an underwater guide rail mounting seat structure of a flow promoter. Background Art

[0002] A flow pusher is a mechatronic submersible device whose impeller is driven to rotate by a motor reduction mechanism. It is widely used in the field of urban domestic sewage treatment. It stirs sewage, mixes sludge, promotes the flow of water media, and blocks sludge sedimentation. It is a key core equipment in sewage treatment plants. It consists of three major parts: one is the flow pusher host, the second is the underwater guide rail mounting seat, and the third is the lifting device. The main unit of the equipment works at a position of about 5-7 meters underwater, so the underwater guide rail mounting seat is fixed to the bottom of the underwater pool, and the lifting device is installed on the surface of the pool above water. The flow pusher host is lifted by the lifting device above water, lowered and slid along the guide rail, and put into place to work on the underwater pool bottom mounting seat. If it needs to be pulled up, it is directly lifted by the lifting device and moved up along the guide rail.

[0003] Traditional underwater rail mounts usually bury the lower end of the rail under the bottom wall of the selection tank, and may even be fixed with expansion bolts. During long-term operation, the motor of the flow pusher will generate certain vibrations, which will cause the bottom of the underwater rail mount to break or other failures. At present, it is common to first shut down the selection tank partially or completely, then drain the water, clean the sludge at the bottom of the tank, and then repair or replace the rail mount. This maintenance method, which involves shutting down the water supply and operation, will not only affect the operation of the sewage treatment system, causing environmental pressure and economic losses, but also has a long maintenance cycle and consumes manpower. After the maintenance is completed, the selection tank must be re-inoculated with activated sludge for debugging, and the procedure is very cumbersome.

[0004] Therefore, it is necessary to design a new underwater guide rail mounting seat structure for the flow promoter, which can reduce the risk of damage caused by the vibration of the flow promoter on the one hand, and on the other hand, the underwater guide rail mounting seat can be maintained without stopping water supply or operation even if it is damaged, so as to avoid affecting the normal operation of the sewage treatment system. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an underwater guide rail mounting seat structure for a flow pusher, so as to avoid the problems of the underwater guide rail mounting seat of the existing flow pusher being troublesome to maintain and requiring water outage and operation suspension, and being not easily damaged during operation.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A flowmaker underwater guide rail mounting seat structure comprises a vertical guide rail and a horizontal support, wherein the upper end of the guide rail is connected to one end of the support, and the other end of the support is fixed to the side wall of a selection pool; a horizontal saddle is fixedly connected to the lower part of the guide rail on the side opposite to the support for placing a flowmaker host; a conical anchor pin is connected to the lower end of the guide rail, and the pointed end of the conical anchor pin is vertically downward and inserted into the pool bottom to a certain depth.

[0008] To further improve the above technical solution, a circle of counterweight is formed on the guide rail between the conical anchor pin and the saddle along the circumferential protrusion of the guide rail.

[0009] Further, the lower end of the guide rail is vertically inserted into a counterweight box and fixed to the counterweight box, and the conical anchor pin is connected to the lower surface of the counterweight box;

[0010] A weight box is formed as the weight portion.

[0011] Furthermore, the counterweight box comprises a cylindrical shell with an open top, the lower end of the guide rail is fixed to the bottom wall of the cylindrical shell, and the remaining space in the cylindrical shell is poured with concrete to form a counterweight;

[0012] The large end of the conical anchor pin is fixed to the lower surface of the cylindrical shell.

[0013] Furthermore, the support comprises a horizontal rectangular frame, the inner short side of the rectangular frame is fixed to the side wall of the selection tank, and the upper end of the guide rail is connected to the middle part of the other short side.

[0014] Furthermore, two first diagonal braces symmetrical to the guide rail are provided between the rectangular frame and the saddle, one end of the two first diagonal braces is connected to the position corresponding to the saddle on the guide rail, and the other end extends obliquely upward to respectively connect to the two ends of the inner short side of the rectangular frame.

[0015] Furthermore, a second diagonal brace is provided between the saddle and the counterweight, one end of the second diagonal brace is connected to the guide rail section between the saddle and the counterweight, and the other end of the second diagonal brace extends obliquely upward to be connected to the lower surface of the free end of the saddle.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model provides an underwater guide rail mounting seat structure for a flow pusher. In this structure, the lower end of the guide rail is no longer buried and fixed in the bottom wall of the selection pool. Instead, a conical anchor pin with a pointed end facing downward is provided at the lower end of the guide rail. Positioning is achieved by the conical anchor pin. When in use, the conical anchor pin will be inserted 20-30 mm into the ground, which can keep the guide rail in a vertical state in the selection pool without displacement. At the same time, there is no mounting structure at the lower end of the conical anchor pin that is fixed to the bottom of the pool, so that the conical anchor pin will not be broken due to the vibration caused by the operation of the flow pusher, which effectively increases the service life of the entire underwater guide rail mounting seat. Even if maintenance is required, there is no need to stop the water supply or operation. The entire underwater guide rail mounting seat can be lifted upward out of the selection pool, which is convenient for maintenance and replacement.

[0018] 2. The underwater guide rail mounting seat structure of a flow promoter of the utility model has limited weight and the lower end of the guide rail is not fixed to the bottom wall of the selection pool. The vibration caused by the operation of the upper flow promoter main engine will always cause the conical anchor pin to shake slightly. Providing a counterweight part in the guide rail section between the conical anchor pin and the saddle can reduce the above shaking and further ensure the stability of the lower end of the guide rail, thereby improving the stability of the entire underwater guide rail mounting seat.

[0025] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] See also Figure 1-Figure 3A specific embodiment of an underwater guide rail mounting seat structure for a flow promoter includes a vertical guide rail 1 and a horizontal support, the upper end of the guide rail 1 is connected to one end of the support, and the other end of the support is fixed to the side wall of the selection pool; the lower part of the guide rail 1 is fixedly connected with a horizontal saddle 2 on the side opposite to the support for placing the flow promoter host (not shown in the figure)); the lower end of the guide rail 1 is connected with a conical anchor pin 3, the pointed end of the conical anchor pin 3 is vertically downward and inserted into the pool bottom to a certain depth.

[0027] An underwater guide rail mounting seat structure of a flow pusher in an embodiment no longer buries and fixes the lower end of the guide rail 1 in the bottom wall of the selection pool, but a conical anchor pin 3 with a pointed head facing downward is provided at the lower end of the guide rail 1, and positioning is achieved by the conical anchor pin 3. When in use, the conical anchor pin 3 will be inserted 20-30 mm into the ground, which can keep the guide rail 1 in a vertical state in the selection pool without shifting. At the same time, there is no mounting structure at the lower end of the conical anchor pin 3 that is fixed to the bottom of the pool, so that the conical anchor pin 3 will not be broken due to the vibration caused by the operation of the flow pusher main unit, which effectively increases the service life of the entire underwater guide rail mounting seat. Even if maintenance is required, there is no need to stop the water supply and operation. The entire underwater guide rail mounting seat can be lifted upward out of the selection pool, which is convenient for maintenance and replacement.

[0028] Wherein, a circle of counterweight is formed on the guide rail 1 between the conical anchor pin 3 and the saddle 2 along the circumferential protrusion of the guide rail 1 .

[0029] In this way, due to its limited weight and the fact that the lower end of the guide rail 1 is not fixed to the bottom wall of the selection pool, the vibration caused by the operation of the upper flow promoter main unit will always cause the conical anchor pin 3 to shake slightly. By providing a counterweight portion in the guide rail section between the conical anchor pin 3 and the saddle 2, the above-mentioned shaking can be reduced, further ensuring the stability of the lower end of the guide rail 1, thereby improving the stability of the entire underwater guide rail mounting seat.

[0030] See also Figure 1-Figure 3 During implementation, the lower end of the guide rail 1 is vertically inserted into a counterweight box 5 and fixed to the counterweight box 5, and the conical anchor pin 3 is connected to the lower surface of the counterweight box 5;

[0031] The weight box 5 is formed as the weight portion.

[0032] Specifically, the counterweight box 5 includes a cylindrical shell with an open top, the lower end of the guide rail 1 is fixed to the bottom wall of the cylindrical shell, and the remaining space in the cylindrical shell is poured with concrete to form a counterweight;

[0033] The large end of the conical anchor pin 3 is fixed to the lower surface of the cylindrical shell.

[0034] During installation, first process the conical anchor pin 3 and the counterweight box 5 according to the design dimensions. The cylindrical shell of the counterweight box 5 can be made of a DN500 seamless steel pipe, and then the lower end of the cylindrical shell is welded with a steel plate to seal it; then the lower end of the guide rail 1 is welded and fixed to the middle part of the bottom wall of the cylindrical shell, and then concrete is poured into the cylindrical shell until the concrete solidifies to obtain the annular counterweight, and finally the big head end of the conical anchor pin 3 is welded to the middle part of the lower surface of the cylindrical shell.

[0035] The support comprises a horizontal rectangular frame 6, the inner short side of the rectangular frame 6 is fixed to the side wall of the selection tank, and the upper end of the guide rail 1 is connected to the middle part of the other short side.

[0036] During implementation, the rectangular frame 6 is welded by four square steels with a specification of 100*100*6. The long side of the entire rectangular frame 6 is 2000 mm and the short side is 1200 mm.

[0037] See also Figure 1 and Figure 2 Among them, two first diagonal braces 7 symmetrical with respect to the guide rail 1 are provided between the rectangular frame 6 and the saddle 2, one end of the two first diagonal braces 7 is connected to the position corresponding to the saddle 2 on the guide rail 1, and the other end extends obliquely upward to be connected to the two ends of the inner short side of the rectangular frame 6 respectively.

[0038] So, from Figure 1 It can be seen that the length of the guide rail section above the saddle 2 is much longer than that of the guide rail section below, and the guide rail 1 is fixed to the rectangular frame 6 only through the upper end. Two first diagonal braces 7 are further provided to increase the connection strength between the guide rail 1 and the upper rectangular frame 6, increase the structural stability of the entire underwater guide rail mounting seat, and also play a shock-absorbing role.

[0039] Please continue to see Figure 1 A second diagonal brace 8 is provided between the saddle 2 and the counterweight part, one end of the second diagonal brace 8 is connected to the guide rail section between the saddle 2 and the counterweight part, and the other end extends obliquely upward to be connected to the lower surface of the free end of the saddle 2.

[0040] In this way, the second diagonal brace 8 can provide effective support for the horizontal saddle 2, and can also further reduce the impact of the vibration of the flowmaker mainframe on the lower guide rail section.

[0041] During implementation, the second diagonal brace 8 and the two first diagonal braces 7 are made of square steel with a specification of 80*80*5, and the saddle 2 is made of square steel with a specification of 100*100*6.

[0042] During installation, the underwater guide rail mounting seat structure of the flow booster of this embodiment is first placed at a preset position, and is vertically lowered into the selection pool through a lifting device, and a certain gravity is applied downward so that the conical anchor pin 3 is inserted into the bottom wall of the selection pool by 20-30 mm, and then the short side of the rectangular frame 6 away from the guide rail 1 is fixed to the side wall of the selection pool. When the entire underwater guide rail mounting seat needs to be taken out for maintenance or replacement, the fixing structure between the rectangular frame 6 and the side wall of the selection pool is removed, and then the entire underwater guide rail mounting seat is lifted out with a lifting device.

[0043] In the present invention, the cross-sectional shape of the guide rail 1 should be a structure that can slide with the main unit of the flowmaker, which belongs to the prior art and only needs to ensure that the main unit of the flowmaker can be limited in the front, back, left and right directions, which will not be elaborated here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
