Description

Technical Field

[0001] The utility model relates to the technical field of manhole detector placement, in particular to a placement rod and a detection device. Background Art

[0002] Manholes are underground spaces used for transit and control of urban underground pipe networks. Their surface entrances and exits are called manhole openings or manholes and are usually covered by manhole covers. The primary function of manholes is to facilitate the maintenance and installation of underground infrastructure (such as power supply, water supply, drainage, communications, cable television, gas pipelines, and streetlight lines). Manholes are essential structures in rainwater / sewage drainage networks and are important facilities for facilitating daily inspections, preventing blockages, and unblocking pipes. Manhole water levels can intuitively and accurately reflect the operating status of urban drainage pipelines, effectively identify silted pipe sections, and promptly detect abnormalities in manhole covers, enabling rapid flood control responses and ensuring the safety of residents.

[0003] When installing equipment on site in an underground pipe network, the detector needs to be placed deep into the pipe and fixed in a certain orientation to work properly. According to the different pipe depths, the use of a combination of multi-section installation pipes can easily achieve the installation of the equipment in a very deep pipe. The equipment installer can complete the installation of the equipment as required without having to go down to the bottom of the well. This not only reduces the labor intensity of the installer, but also ensures the safety of the installer. Currently, the detector is usually placed using a placement rod. The existing placement rod is prone to swinging when the detector is performing various data detection in the manhole, which can lead to errors in the detection data and even metal fatigue of the placement rod, causing the placement rod to break.

[0027] The present invention provides a casting rod 100 .

[0028] See also Figures 1 to 4In one embodiment of the present utility model, the dropping rod 100 includes: a mounting tube 1, a connecting part 2, a sliding part 3 and a fixing part 4, the connecting part 2 is used to fix the mounting tube 1 on the side wall of the manhole; the sliding part 3 is detachably connected to the mounting tube 1, and the sliding part 3 is located at the end of the mounting tube 1 away from the connecting part 2; the fixing part 4 is connected to the mounting tube 1, and the fixing part 4 is located at the end of the mounting tube 1 away from the connecting part 2; the fixing part 4 is used to fix the mounting tube 1 on the bottom wall of the vertical manhole.

[0029] In one embodiment, considering the often humid environment within manholes and the potential presence of corrosive substances, the material selected for the deployment rod 100 should exhibit excellent corrosion resistance. The mounting tube 1, the main component of the deployment rod 100, is typically a round tube with an internal wire passage. It is typically constructed from corrosion-resistant, lightweight, yet strong materials, such as 304 stainless steel, 316 stainless steel, or carbon fiber, to ensure its ability to withstand gravity and resist bending. The thickness of the mounting tube 1 is typically 1-2 mm, ensuring overall strength while also ensuring that the overall weight does not exceed the operator's tolerance or the load-bearing capacity of the connection 2. The overall diameter of the mounting tube 1 is 2-5 cm, ensuring adequate torsional strength while also providing an internal wire passage. The mounting tube 1 is secured to the sidewall of the manhole opening via the connection 2. This requires sufficient grip and stability, typically achieved with expansion bolts or clips, to facilitate subsequent disassembly or replacement. The mounting tube 1 includes a wire passage to accommodate the detector's electrical signal transmission wires.

[0030] Among them, the design of the connecting part 2 needs to take into account the size and shape of the manhole opening to ensure that the mounting tube 1 can be firmly connected to the manhole opening. In terms of material, durable and corrosion-resistant engineering plastics or stainless steel materials can be used to adapt to the outdoor environment and resist the erosion of chemical substances. The function of the sliding part 3 is to install the detector so that the detector can slide along the mounting tube 1 to adapt to manholes with different liquid level depths. It should be noted that the fixing part 4 is connected to the mounting tube 1 and is located at the other end of the mounting tube 1. It is used to fix the end of the mounting tube 1 close to the detector on the bottom wall of the vertical manhole to ensure that the detector can stably perform data detection after being deployed. This design improves the stability of the deployment process and reduces the detection data error caused by swinging; through the setting of the fixing part 4, the stability of the detector in the manhole is enhanced, and the stability of the detector is avoided due to changes in the internal environment of the manhole. In terms of material, the fixing part 4 generally uses high-strength plastic or metal to ensure stability and reliability when fixing the detector.

[0031] The delivery rod 100 proposed in the present invention achieves the purpose of stable delivery and fixation of the detector through a specific structural design. Specifically, the mounting tube 1, as the main part of the delivery rod 100, is fixed to the side wall of the manhole opening through the connecting portion 2, thereby ensuring the basic stability of the delivery rod 100. The sliding portion 3 is designed to slide on the mounting tube 1, so that the detector can adjust the position of the sliding portion 3 in the manhole along the axial direction of the mounting tube 1. The sliding portion 3 is located at the end of the mounting tube 1 away from the connecting portion 2. Such a design can increase the adaptation range of the delivery rod 100, and improve the flexibility of delivery by using mounting tubes 1 of different lengths to adapt to the depth of the manhole. The fixing portion 4 is connected to the mounting tube 1 and is located at the other end of the mounting tube 1. It is used to fix the end of the mounting tube 1 close to the detector on the bottom wall of the vertical manhole, ensuring that the detector can stably perform data detection after delivery. This design improves the stability of the deployment process and reduces the detection data error caused by swinging; through the setting of the fixed part 4, the stability of the detector in the manhole is enhanced, and the stability of the detector is avoided from being affected by changes in the internal environment of the manhole; the design of the sliding part 3 enables the deployment rod 100 to adjust the position of the detector according to actual needs to adapt to manholes with different liquid level depths, thereby improving the flexibility and adaptability of use; the overall structural design takes into account the convenience of operation and the ease of maintenance, which helps to improve the efficiency and safety of the detection work.

[0032] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 The fixing portion 4 includes a rod tip 41 , which is connected to the mounting tube 1 . The rod tip 41 is located at an end of the mounting tube 1 away from the connecting portion 2 .

[0033] The rod tip 41 of the fixing portion 4 is designed to be connected to one end of the mounting tube 1 and extend to a position away from the connecting portion 2 so that it can penetrate into the interior of the manhole and be fixed to the bottom structure of the manhole. The specific implementation method is as follows: First, the rod tip 41 is usually made of a strong and corrosion-resistant material, such as stainless steel or high-strength engineering plastics, to ensure its durability in the harsh manhole environment. Then, the rod tip 41 is tightly connected to the end of the mounting tube 1 by threaded connection, welding or a special fixing fixture to ensure the stability and sealing of the connection. After connection, the rod tip 41 will be placed and fixed at the bottom of the vertical manhole so that it is firmly embedded in the soil or concrete at the bottom of the manhole, thereby ensuring the stability of the entire deployment rod 100 during use and preventing displacement or falling off due to groundwater flow or external forces.

[0034] In one embodiment of the present invention, please refer to Figure 2The connecting part 2 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are detachably connected. The first clamping member 21 and the second clamping member 22 are both located at the end of the mounting tube 1 away from the rod tip 41. The first clamping member 21 and the second clamping member 22 enclose a clamping channel 2a to clamp the mounting tube 1.

[0035] In the present invention, in order to facilitate the installation and fixation of the mounting tube 1, a unique clamping structure is designed for the connecting portion 2, which includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are connected to each other by a detachable connection method, such as using bolts, snaps or a quick release mechanism, so that they can be quickly assembled or disassembled when needed. The first clamping member 21 and the second clamping member 22 are both located at the end of the mounting tube 1 away from the rod tip 41, which can ensure that the installer can operate the clamping structure at a position close to the manhole opening without being restricted by the internal space of the manhole. Specifically, the first clamping member 21 and the second clamping member 22 are the main parts of the clamping channel 2a, which are enclosed to form the clamping channel 2a for clamping the mounting tube 1. The first clamping member 21 and the second clamping member 22 can be made of high-strength engineering plastics or stainless steel materials to ensure the durability and reliability of the clamping structure. The clamping channel 2a is designed to have a certain degree of elasticity or adjustability to adapt to installation tubes 1 of different diameters, ensuring stability and sealing during clamping. During the installation process, the installation tube 1 is first inserted into the clamping channel 2a, and then the distance between the first clamping member 21 and the second clamping member 22 is adjusted so that they form a clamping state on the installation tube 1. This clamping state can be achieved by adjusting the tightening force of the bolts on the clamping members or by locking through a snap mechanism. Once the clamping members are fixed in place, they will tightly clamp the installation tube 1 to prevent it from sliding or falling off inside the manhole, ensuring the stability and safety of the deployment rod 100 in the manhole. This design not only improves the convenience of operation, but also increases the flexibility of use, allowing the operator to adjust the deployment rod 100 at the manhole entrance without entering the bottom of the manhole, which is highly safe.

[0036] In one embodiment of the present invention, please refer to Figure 2 The connecting portion 2 further includes a mounting plate 23 , which is connected to the first clamping member 21 . The mounting plate 23 is located on a side of the first clamping member 21 facing away from the second clamping member 22 .

[0037] In one embodiment, the mounting plate 23 is directly connected to the first clamping member 21 and is located on the side of the first clamping member 21 facing away from the second clamping member 22. This arrangement allows the mounting plate 23 to provide stable support and fixation in the space-constrained manhole environment. Specifically, the mounting plate 23 can be connected to the first clamping member 21 by welding, bolting, or other appropriate fixing methods. The mounting plate 23 is generally designed to have sufficient rigidity and strength to withstand the weight of the mounting tube 1 and the detector. Materials for the mounting plate 23 may include stainless steel, aluminum alloy, or other high-strength engineering plastics that provide the required durability and corrosion resistance. During installation, the mounting plate 23 is first positioned on the side wall of the manhole opening, and then the first clamping member 21 is secured to the mounting plate 23 by bolts, welding, or other means. The position and design of the mounting plate 23 ensure that it effectively connects the first clamping member 21 to the manhole structure while providing a stable support point for the mounting tube 1. This structure not only improves the stability of the entire connecting portion 2, but also helps to disperse the forces that may act on the mounting tube 1, thereby protecting the connecting portion 2 from damage and ensuring the reliability and safety of the casting rod 100 during use.

[0038] In one embodiment of the present invention, please refer to Figure 2 The connecting portion 2 also includes at least two first clamping members 21 and at least two second clamping members 22. Each first clamping member 21 is detachably connected to a second clamping member 22. Each first clamping member 21 and a second clamping member 22 are located at an end of the mounting tube 1 away from the rod tip 41. Each first clamping member 21 and a second clamping member 22 enclose a clamping channel 2a to clamp the mounting tube 1.

[0039] In this embodiment, a configuration of at least two first clamping members 21 and at least two second clamping members 22 is adopted to enhance the clamping force of the connecting portion 2 and the stability of the launching rod 100. Each first clamping member 21 is connected to one of the second clamping members 22 by a detachable connection method, such as using bolts, snaps, or other quick-release mechanisms, so that they can be easily assembled or disassembled when needed. Each first clamping member 21 and each second clamping member 22 are located at the end of the mounting tube 1 away from the rod tip 41. This layout allows the clamping structure to tightly fit the end of the mounting tube 1 near the manhole opening against the side wall of the manhole opening, thereby providing a stable fixation. The first clamping member 21 and the second clamping member 22 enclose a clamping channel 2a, which is specifically used to clamp the mounting tube 1. The first clamping member 21 and the second clamping member 22 can be connected together by bolts, snaps, or other fixing methods to form a stable structure to ensure that the mounting tube 1 is firmly fixed in the clamping channel 2a. The design of this clamping structure not only provides a strong clamping force, but also allows for quick installation and removal, facilitating maintenance and replacement.

[0040] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 The casting rod 100 also includes at least two mounting tubes 1, each mounting tube 1 is connected end to end in sequence, the mounting tube 1 close to the clamping channel 2a is connected to the clamping channel 2a, and the mounting tube 1 close to the rod tip 41 is connected to the rod tip 41.

[0041] In this embodiment, the length of the deployment rod 100 is adjusted by installing different numbers of mounting tubes 1 to adapt to manholes of different depths. The mounting tubes 1 are connected end to end in sequence to form a long rod extending in the axial direction of the mounting tube 1, so that the length of the entire deployment rod 100 can be adjusted as needed. Specifically, each mounting tube 1 can be a standard length steel pipe or a tubular structure made of high-strength material. They need to have sufficient strength and durability to withstand the tensile, compressive and torsional forces that may be encountered during operation in the manhole. The mounting tubes 1 can be connected to each other by threaded connection, slot connection or other mechanical connection methods. These connection methods should be able to ensure the firmness of the connection and ensure that the mounting tubes do not rotate with each other. At the same time, they should also be convenient for rapid assembly and disassembly on site. The mounting tube 1 near the clamping channel 2a is connected to the clamping channel 2a. This connection needs to ensure stability throughout the use process to prevent falling off or sliding due to loosening. The connecting tube near the rod tip 41 is also connected to the rod tip 41 through a reliable connection method. This connection must not only ensure the stability of the structure, but also ensure that the rod tip 41 can be flexibly operated at the bottom of the manhole. This layout allows the deployment rod 100 to be depth-adjusted within the manhole while providing the necessary support and stability. The material selection for the mounting tube 1 should take into account corrosion resistance, strength and weight. Common materials include stainless steel, aluminum alloy or high-density polyethylene (HDPE), etc., which can provide the required mechanical properties while reducing the weight of the overall deployment rod 100. Through this design, the deployment rod 100 can not only adapt to manholes of different depths, but also can quickly adjust the length when necessary to adapt to different operating environments and requirements. In addition, the design of the mounting tube 1 also takes into account the convenience of maintenance and replacement, ensuring the long-term and stable use of the deployment rod 100.

[0042] In one embodiment of the present invention, please refer to Figure 4 The sliding portion 3 includes a sliding arm 31 and a sliding clamp 32. The sliding arm 31 and the sliding clamp 32 are detachably connected. The sliding arm 31 and the sliding clamp 32 form a sliding channel 3a. The sliding portion 3 is connected to the mounting tube 1 through the sliding channel 3a.

[0043] In one embodiment, the sliding portion 3 can slide within a certain range on the mounting tube 1 to accommodate inspections of manholes with varying liquid depths. The sliding portion 3 consists of a sliding arm 31 and a sliding clamp 32, which together form a sliding channel 3a. The sliding portion 3 is connected to the mounting tube 1 through the sliding channel 3a. Specifically, the sliding arm 31 can be an arm-shaped structure made of metal or high-strength plastic, providing sufficient strength and rigidity to support the weight of the detector. The sliding clamp 32 mates with the sliding arm 31 and can be made of the same or different materials. Its function is to enclose the sliding channel 3a with the sliding arm 31 and provide the necessary clamping force to prevent the detector from slipping relative to the mounting tube 1 during inspection. The connection between the sliding arm 31 and the sliding clamp 32 utilizes a detachable design, such as a bolt connection, a snap-fit ​​connection, or other quick-release mechanism. This design allows for quick assembly and disassembly of the sliding portion 3 when needed, facilitating maintenance and replacement. The sliding arm 31 and sliding clamp 32 can slide on the mounting tube 1 through the sliding channel 3a without completely separating from the mounting tube 1. This design allows the mounting pipe 1 to be adjusted according to the depth of the manhole or operational requirements while remaining stable and safe.

[0044] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 The sliding arm 31 also includes a flow guide 311, which is connected to the sliding arm 31. The flow guide 311 is located at one end of the sliding arm 31 away from the sliding clamping member 32, and the cross-sectional area of ​​the flow guide 311 gradually decreases in the direction in which the sliding arm 31 moves away from the mounting tube 1.

[0045] In one embodiment, the sliding arm 31 further includes a flow guide 311, which is connected to the sliding arm 31 via bolts or a fixed connection. The flow guide 311 is located at the end of the sliding arm 31 away from the sliding clamp 32, facilitating the detector's detection of the fluid within the manhole. The flow guide 311 is a one-piece sheet metal component. This design significantly reduces the overall weight of the flow guide 311, alleviating the load-bearing burden on the operator and the mounting tube 1. The cross-sectional area of ​​the flow guide 311 is designed to gradually decrease from the end closest to the mounting tube 1 to the end further away from the mounting tube 1. This design not only facilitates the installation and securing of the detector but also reduces material usage, achieving a lightweight structure.

[0046] In one embodiment of the present invention, please refer to Figure 4 A connecting hole is provided on the mounting tube 1 , and the connecting hole is communicated with the inner cavity of the mounting tube 1 .

[0047] In this embodiment, the connection hole design on the sliding arm 31 allows the inner cavity of the mounting tube 1 to communicate with the internal space of the sliding arm 31. Such a design is generally used to ensure the structural stability and operational flexibility between the mounting tube 1 and the sliding arm 31. Specifically, connection holes are designed and opened on the sliding arm 31. The size and position of these holes need to be determined according to the size of the electrical signal transmission wire to ensure that they can be connected with the inner cavity of the mounting tube 1 and the wires can be placed. During the assembly process, ensure that the sliding arm 31 is correctly aligned with the mounting tube 1, and fix them together with bolts, pins or other fasteners to ensure that the connection hole is connected with the inner cavity of the mounting tube 1. Through this design, the casting rod 100 can not only provide stable support and precise positioning, but also transmit the electrical signals in the detector to the manhole mouth through the connection hole and the inner cavity of the mounting tube 1, so as to facilitate the operator to perform real-time detection of signals in the manhole.

[0048] The present invention also provides a detection device, which includes a detector and a delivery lever 100. The specific structure of the delivery lever 100 is similar to the above-mentioned embodiment. Since the present detection device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. The detector is connected to the sliding part 3.

[0049] In this embodiment, the detector is connected to the sliding part 3 by means of bolts or snaps, etc. This connection method needs to be strong enough to ensure that the detector will not fall off due to the movement of the sliding arm 31 when performing detection inside the manhole. At the same time, due to the design of the rod tip 41 of the fixing part 4, the detector is more stable on the sliding part 3 of the delivery rod 100 to ensure the accuracy of the detection data. Through the above design, the detection device can achieve stable delivery and precise positioning of the detector in the manhole, while ensuring the ease of operation and durability of the equipment. The operator does not need to go down to the inside of the manhole to install the detector, which greatly improves the safety of the detection process. This design is particularly suitable for occasions where detailed detection or monitoring is required in the manhole, such as pipeline leakage detection, fluid monitoring, etc.

[0050] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
