Description

Technical Field

[0001] This application relates to the field of urban underground pipeline monitoring technology, and in particular to an installation device for an ultrasonic radar flow meter for underground pipelines. Background Technology

[0002] Underground pipeline flow meters include mounting brackets, which are crucial core components. The structural performance of these brackets determines the flow meter's measurement accuracy and reliability. Existing flow meter mounting brackets typically need to be customized based on the pipeline depth to determine their specific length, ensuring they can penetrate deep into the manhole. They are generally fixed to the pipeline network at the midpoint using expansion bolts. Existing underground pipeline flow meter mounting brackets present the following problems during installation:

[0003] 1. The installation position of the flow meter on the inner wall of the pipeline is relatively fixed. When the manhole is deep, construction personnel need to go deep into the manhole to install it. However, the conditions in the manhole are harsh, and it is inconvenient for personnel to go down into the manhole to install it manually. There is also a possibility of endangering the personal safety of the construction personnel.

[0004] 2. Low installation accuracy: During installation, the flow meter is usually only roughly determined by visual inspection to be aligned with the direction of fluid flow, which makes it impossible to complete the precise assembly of the flow meter. Furthermore, it cannot be calibrated during later maintenance, which ultimately affects the service life of the flow meter. Summary of the Invention

[0005] The purpose of this application is to provide an installation device for an ultrasonic radar flow meter in underground pipe networks to solve at least one of the above-mentioned technical problems.

[0006] An installation device for an ultrasonic radar flow meter in an underground pipeline network includes a bracket, an extension rod, and a back plate. The bracket is detachably connected to one end of the extension rod, and the extension rod is perpendicular to the bracket. One side of the back plate can be fixedly connected to the side wall of the manhole, and the other side of the back plate is provided with a reinforcing member. The extension rod can pass through the reinforcing member and is clamped by the reinforcing member. The bracket is provided with at least one first positioning hole, and the reinforcing member is provided with at least one second positioning hole. The first positioning hole and the second positioning hole can coincide in position in the direction perpendicular to the bracket.

[0007] Its beneficial effects are: relevant construction personnel do not need to go down into the well to install the flow meter; they can complete the installation of the fixing device from above the well. This improves the installation efficiency of the flow meter and protects the personal safety of the construction personnel. Construction personnel can use laser irradiation to ensure that the laser can enter the second positioning hole and pass through the first positioning hole, thereby determining whether the installation is in place. This facilitates accurate assembly by construction personnel and makes it easy to calibrate later, ultimately extending the service life of the fixing device.

[0008] In some embodiments, the extension rod includes a rod body, with a first external thread and a second external thread respectively provided at the upper and lower ends of the rod body.

[0009] In some embodiments, the extension rod also includes a suspension member with a first internal thread at its bottom, and a first external thread that can be screwed into or out of the first internal thread.

[0010] In some embodiments, the extension rod includes a connector, the upper and lower ends of which are detachably connected to a suspension component and a rod body, respectively, and a third internal thread is provided inside the connector;

[0011] The extension rod includes a suspension component, the bottom of which is provided with a third external thread, which can be screwed into or out of a third internal thread; the first external thread can be screwed into or out of the third internal thread.

[0012] In some implementations, a hook is attached to the top of the suspension element.

[0013] Its beneficial effect is that the hook can be connected to a lifting device for handling and moving.

[0014] In some embodiments, the bracket is provided with a second internal thread, and the second external thread can be screwed into or out of the second internal thread.

[0015] In some embodiments, the reinforcement includes a fixing block attached to the back plate, one side of which has a slot that matches the circumferential shape of the rod.

[0016] In some embodiments, the reinforcement also includes a limiting block connected to the fixing block, the shape of one side of the limiting block being able to match the circumferential shape of the rod.

[0017] Its beneficial effect is that the fixing block and the limiting block work together to tighten the rod.

[0018] In some implementations, reinforcing ribs are provided at the connection between the back plate and the reinforcement.

[0019] Its beneficial effect is that the bending strength of the connection is improved by setting reinforcing ribs.

[0020] In some implementations, the bracket has a mounting slot.

[0021] In some implementations, a flow monitoring device can be connected to the mounting slot.

[0022] Its beneficial effect is that the flow monitoring device can monitor the water flow rate in the well. Attached Figure Description

[0034] like Figures 1-5 As shown,

[0035] An installation device for an ultrasonic radar flow meter in an underground pipeline network includes a bracket 1, an extension rod 2, and a back plate 3. The bracket 1 is detachably connected to one end of the extension rod 2, and the extension rod 2 is perpendicular to the bracket 1. One side of the back plate 3 can be fixedly connected to the side wall of the manhole, and the other side of the back plate 3 is provided with a reinforcing member 4. The extension rod 2 can pass through the reinforcing member 4 and is clamped by the reinforcing member 4. The bracket 1 is provided with at least one first positioning hole 11, and the reinforcing member 4 is provided with at least one second positioning hole 41. The first positioning hole 11 and the second positioning hole 41 can coincide in position in the direction perpendicular to the bracket 1.

[0036] The back plate 3 is provided with fastener holes through which bolts can pass. In this embodiment, four fastener holes are provided, so the fastener holes on the back plate 3 can be fixedly connected to the side wall of the well by bolts.

[0037] Its beneficial effects are: relevant construction personnel do not need to go down into the well to install the flow meter; they can complete the installation of the fixing device from above the well. This improves the installation efficiency of the flow meter and protects the personal safety of the construction personnel. Construction personnel can use laser irradiation to ensure that the laser can enter the second positioning hole 41 and pass through the first positioning hole 11, thereby determining that the back plate 3 is perpendicular to the bracket 1. This facilitates accurate assembly by construction personnel and makes subsequent calibration easier, ultimately improving the service life of the fixing device.

[0038] Preferably, the extension rod 2 includes a rod body 24, and the upper end and lower end of the rod body 24 are respectively provided with a first external thread 21 and a second external thread 22.

[0039] In the first embodiment, the extension rod 2 further includes a suspension member 23, the bottom of which is provided with a first internal thread 231, and the first external thread 21 can be screwed into or out of the first internal thread 231.

[0040] In the first embodiment, the suspension member 23 is configured with an internal thread and the upper end of the rod 24 is configured with an external thread. After the two are screwed in, their outer curved surfaces are essentially on the same plane. This will bring the risk of the suspension member 23 falling off, especially when you want to adjust the suspension angle. If the suspension member 23 is not properly attached to the equipment, there is a risk of it falling off.

[0041] To overcome the risk of the suspension member 23 falling off in the first embodiment, a new second embodiment is introduced. In the second embodiment, the extension rod 2 includes a connector (not shown in the figure), and the upper and lower ends of the connector are detachably connected to the suspension member 23 and the rod body 24, respectively. The connector is provided with a third internal thread. In this embodiment, the connector is preferably an internal thread connector.

[0042] The extension rod includes a suspension member 23, and the bottom of the suspension member is provided with a third external thread, which can be screwed into or out of the third internal thread; the first external thread 21 can be screwed into or out of the third internal thread.

[0043] Preferably, the top of the suspension member 23 is connected to a hook 232.

[0044] Its beneficial effect is that hook 232 can be connected to a lifting device for handling and moving.

[0045] Preferably, the bracket 1 is provided with a second internal thread 12, and the second external thread 22 can be screwed into or out of the second internal thread 12.

[0046] Preferably, the reinforcement 4 includes a fixing block 42 connected to the back plate 3, and one side of the fixing block 42 is provided with a slot 421 that can match the circumferential shape of the rod 24.

[0047] Preferably, the reinforcement 4 also includes a limiting block 43, which is connected to the fixing block 42, and the shape of one side of the limiting block can match the circumferential shape of the rod 24.

[0048] Its beneficial effect is that the fixing block 42 and the limiting block 43 work together to tighten the rod 24.

[0049] In this embodiment, bolts can be passed through the left and right ends of the fixing block 42 and the limiting block 43 respectively, and the tightness of the fixing block 42 and the limiting block 43 on the rod body 24 can be adjusted by the bolts.

[0050] Preferably, a reinforcing rib (not shown in the figure) is provided at the connection between the back plate 3 and the reinforcement 4.

[0051] Its beneficial effect is that the bending strength of the connection is improved by setting reinforcing ribs.

[0052] Preferably, the bracket 1 has a mounting groove 13. The mounting groove 13 is arranged along the length direction of the bracket 1. In this embodiment, a mounting groove 13 is provided on the left and right sides of the bracket 1 respectively.

[0053] Preferably, a flow monitoring device can be connected to the mounting slot 13.

[0054] Its beneficial effect is that the flow monitoring device can monitor the water flow rate in the well.

[0055] like Figure 6 As shown, the installation process of the flow meter installation device in the manhole is described in detail below:

[0056] After the bracket 1 and extension rod 2 are assembled together, the reinforcement 4 is tightened on the extension rod 2 near the operator; then the flow meter installation device is lowered into the well through the hoisting device connected at hook 232, and the back plate 3 is fixedly connected to the side wall of the well opening, especially in a position that the operator can reach; the extension rod 2 is extended into the well until the flow monitoring device comes into contact with the water flow in the well, thereby completing the monitoring of the water flow in the well.

[0057] To confirm whether the flow meter installation device is accurately installed, a laser device can be used to illuminate the second positioning hole 41 to see if the laser leaves a projection on the bracket 1 after passing through the second positioning hole 41. If there is a projection, it means that the installation is not in place and the installation position needs to be readjusted. If the laser passes through the second positioning hole 41 and then passes through the first positioning hole 11 (which appears as no projection on the bracket 1), it means that the installation position is correct.

[0058] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of the appended claims. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
