Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to an interception and protection device. Background Art

[0002] In the operation and maintenance of municipal drainage pipelines, ensuring the safety of workers has always been a top priority. In traditional drainage pipeline operations, water blocking airbags are often used to block and intercept water. Although this method can prevent the impact of upstream water to a certain extent, it lacks direct and effective protection for workers in the pipe. Especially when the upstream well blocking fails or water comes unexpectedly, workers are very likely to be rushed into the downstream pipe by the instantaneous water flow, causing unpredictable dangers.

[0003] In recent years, in order to improve operational safety, the industry has tried to add steel mesh to downstream inspection wells as a simple protective measure. This steel mesh is usually set as a fixed structure, which makes it difficult for traditional steel mesh to be fully assembled with the inner wall of the well chamber, greatly reducing the protective effect. In addition, municipal well chambers are mostly set as cylindrical structures of different sizes. The steel mesh of this structure is difficult to adapt to well chambers of different calibers, resulting in poor adaptability and practicality, resulting in greater safety risks in the actual operation process.

[0014] The interception frame also includes an interception rod, which is arranged between any two adjacent support rods and is arranged at a second angle with any support rod.

[0015] In one embodiment, the interception protection device further comprises a pivot member disposed at the center of the interception frame, and the interception frame can be rotated and folded via the pivot member.

[0016] In one embodiment, the intercepting rod is integrally formed with the supporting rod on at least one side.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Example 1: Please refer to Figure 1-4 and Figure 6As shown, the present embodiment provides an interception and protection device 100, which includes an interception frame 110 for intercepting and protecting personnel in the process of operating and maintaining a municipal drainage pipe and a support rod 111 installed on the interception frame 110, the installation direction of the support rod 111 is set toward the inner wall of the well chamber 200, and the length of the support rod 111 is adjustable relative to the inner wall of the well chamber 200 to achieve assembly with well chambers 200 of different calibers; it is understandable that when the operator operates and maintains the municipal drainage pipe, it is necessary to install and fix the interception frame 110 in the well chamber 200 to intercept the operator who is operating the drainage pipe in the well chamber 200, so that when the upstream well plugging fails or water comes unexpectedly, the operator can be intercepted by the interception frame 110 and will not be rushed into the downstream pipe by the instantaneous water flow, and for well chambers 200 of different calibers, the interception frame 110 can be assembled in well chambers 200 of different calibers by adjusting the length of the support rod 111, and it can be fully assembled with the inner wall of the well chamber 200.

[0032] Please refer to Figure 1-2 As shown, specifically, the interception frame 110 includes a limiting rod 121, and a receiving cavity 12a for receiving the support rod 111 is provided in the limiting rod 121. The support rod 111 is movably connected to the limiting rod 121 to perform telescopic movement relative to the receiving cavity 12a. By setting the limiting rod 121 and forming the internal receiving cavity 12a, the support rod 111 can be retracted into the receiving cavity 12a to shorten its length, and the support rod 111 can be extended outward from the receiving cavity 12a to increase its length. In addition, the interception protection device 100 also includes a spring 112 installed in the receiving cavity 12a. The spring 112 is relative to the support rod 111. 1 is arranged at the inner side of the receiving cavity 12a, and the spring 112 abuts against the support rod 111 so that an interaction force is generated between the spring 112 and the support rod 111, so that when the operator needs to increase the length of the support rod 111, the support rod 111 can be quickly ejected from the receiving cavity 12a to the outside through the spring 112, and when the operator needs to shorten the length of the support rod 111, the support rod 111 can be received in the receiving cavity 12a and the spring 112 can be compressed to buffer the support rod 111, so as to prevent the support rod 111 from shrinking too quickly and causing collision, thereby damaging the interception frame 110.

[0033] Please refer to Figure 1-2 and Figure 6As shown, specifically, a limiting fixing portion 122 is provided on the support rod 111, and the limiting fixing portion 122 is provided at one end of the support rod 111 away from the spring 112, and approaches or moves away from the receiving chamber 12a as the support rod 111 is extended or retracted, that is, the limiting fixing portion 122 is provided at the outer end of the support rod 111 for abutting against the inner wall of the well chamber 200, and the limiting fixing portion 122 is used to abut against the outer wall of the well chamber 200 and be detachable and fixed, so that the overall intercepting frame 110 is installed and fixed on the inner wall of the well chamber 200, and the size of the limiting fixing portion 122 is larger than the size of the side of the support rod 111 facing the inner wall of the well chamber 200, so that the limiting fixing portion 122 can be stuck in the cavity opening of the receiving chamber 12a during the process of the support rod 111 shrinking into the receiving chamber 12a, thereby preventing the entire support rod 111 from entering the receiving chamber 12a, making it easier to adjust the length of the support rod 111 when it is used next time.

[0034] Please refer to Figure 1-2 and Figure 6 As shown, specifically, the interception protection device 100 also includes a fixing buckle 113, which is detachably mounted on the limiting rod 121 and the support rod 111, and the fixing buckle 113 is used to fix the relative position of the limiting rod 121 and the support rod 111 located in the receiving cavity 12a of the limiting rod 121; it can be understood that when the operator installs the interception frame 110 in the well chamber 200, the length of the support rod 111 extending outward or contracting inward relative to the limiting rod 121 is adjusted in advance so that the limiting fixing portion 122 at the end of the support rod 111 is aligned with the well chamber 200. 00 is abutted and installed against the inner wall of the well chamber 200, and the fixing buckle 113 is passed through the limit rod 121 and the support rod 111 and the position of the support rod 111 relative to the limit rod 121 is fixed, so that the intercepting frame 110 is installed as a whole on the inner wall of the well chamber 200, and the fixing buckle 113 is set to be detachable, so that when the operator finishes the work, the fixing buckle 113 can be removed from the limit rod 121 and the support rod 111, so that the position of the support rod 111 relative to the limit rod 121 can be moved, so that the support rod 111 can be retracted into the accommodating cavity 12a of the limit rod 121.

[0035] Please refer to Figure 1 , 36, specifically, the number of support rods 111 is set to four, and the number of limit rods 121 matches the number of support rods 111. It can be understood that in some embodiments, the cross-sectional diameter of the well chamber 200 is circular, while in other embodiments, the cross-sectional diameter of the well chamber 200 is elliptical or other irregular shapes. The advantage of setting four support rods 111 is that the interception frame 110 can be abutted and fixed to the inner wall of the well chamber 200 in different directions when the cross-sectional shapes of the diameters of different well chambers 200 are different, and the adaptability is better; and the interception frame 110 also includes an interception rod 123, which is set between any two adjacent support rods 111, it can be understood that the purpose of setting the interception rod 123 is to increase the interception effect of the interception frame 110, so as to make it easier to intercept and protect the operating personnel; in addition, any two adjacent support rods 111 are set at a first angle ∠α. The purpose of this structure is to make the support rods 111 face different angles of the inner wall of the well chamber 200, which is beneficial to the stable support effect between the support rods 111 and the inner wall of the well chamber 200, and the interception rod 123 is set at a second angle ∠β with any support rod 111. The purpose of setting the second angle ∠β is to make the interception rod 123 and the support rod 111 face in different directions, so that the interception rod 123 can better play an interception role.

[0036] like Figure 3 As shown, optionally, the first angle ∠α is set to a right angle, and the second angle ∠β is set to an obtuse angle.

[0037] Embodiment 2: This embodiment provides a foldable interception protection device 100, please refer to Figure 1-6 As shown, preferably, the interception protection device 100 includes a pivot 114 arranged in the center of the interception frame 110, and the interception frame 110 can be rotated and folded via the pivot 114; it can be understood that in this embodiment, four interception rods 123 are provided, and two of the interception rods 123 are integrally formed with the support rods 111 on both sides, and the other two interception rods 123 are integrally formed with the support rods 111 on one side of the adjacent side. The purpose of this structure is to cooperate with the folding of the interception frame 110, that is, the two interception rods 123 on the folding axis of the interception frame 110 are set to a two-section structure, so that the interception The frame 110 is smoothly folded, and the advantage of folding is that when the wellhead of the well chamber 200 is inconsistent with the diameter of the well chamber 200, for example, when the diameter of the drainage pipe is too large (such as a diameter of 1 meter), and the size of the manhole cover is limited (such as 70 cm), that is, the wellhead size of the well chamber 200 is larger than the diameter of the well chamber 200, it is necessary to fold the interception frame 110 so that the interception frame 110 can smoothly pass through the wellhead of the well chamber 200 into the pipe, and can also be opened in the pipe and installed against the inner wall, thereby further improving the adaptability of the interception and protection device 100.

[0038] Please refer to Figure 1-5 As shown, specifically, the pivot member 114 includes a first pivot hinge 131 and a second pivot hinge 132 pivotally connected to the first pivot hinge 131, and the interception protection device 100 also includes a limit shaft 115 and a limit buckle 116; wherein the limit buckle 116 is fixedly connected to the second pivot hinge 132. Optionally, in this embodiment, a limit slot 13a matching the limit shaft 115 is provided on the first pivot hinge 131 and the second pivot hinge 132, and the limit shaft 115 passes through the limit slot 13a and is pivotally connected to the limit buckle 116. This structure is that the limit shaft 115 can be rotated with the limit buckle 116 as the pivot axis so that it can enter the limit slot 13a from the side of the first pivot hinge 131 and the second pivot hinge 132, thereby limiting the movement of the first pivot hinge 131. At this time, the first pivot hinge 131 is limited so that it cannot pivot relative to the second pivot hinge 132. Movement so that the intercepting frame 110 can be opened and fixed; at the same time, the limit shaft 115 can also rotate with the limit buckle 116 as the pivot axis so that it can be moved out of the limit slot 13a of the first pivot hinge 131 and the second pivot hinge 132, thereby unlocking the movement of the first pivot hinge 131, so that the first pivot hinge 131 can pivot relative to the second pivot hinge 132, so that the intercepting frame 110 forms a folding structure; the purpose of this structure is: when the user needs to send the intercepting frame 110 into the well chamber 200 where the wellhead of the well chamber 200 is inconsistent with the caliber size inside the well chamber 200, the intercepting frame 110 can be folded by adjusting the moving position of the limit shaft 115, and then the intercepting frame 110 is sent into the well chamber 200, and the moving position of the limit shaft 115 is adjusted so that the intercepting frame 110 can be opened, and then the intercepting frame 110 is installed.

[0039] Please refer to Figure 4-5As shown, further, the interception protection device 100 also includes a tightening handle 117, which is installed at one end of the limiting shaft 115 away from the limiting buckle 116 and is threadedly connected to the limiting shaft 115. It can be understood that the tightening handle 117 can be rotated on the limiting shaft 115 by being threadedly connected to the limiting shaft 115. When the limiting shaft 115 is located in the limiting card slot 13a, the operator can rotate the tightening handle 117 clockwise, and the tightening handle 117 will gradually approach the first pivot hinge 131 and squeeze the first pivot hinge 131. In this process, the gap between the first pivot hinge 131 and the second pivot hinge 132 will become smaller and smaller until the first pivot hinge 131 is locked. 131 and the second pivot hinge 132 are completely relatively fixed; in addition, the operator can also rotate the tightening handle 117 counterclockwise, and the tightening handle 117 will gradually move away from the first pivot hinge 131. During this process, the gap between the first pivot hinge 131 and the second pivot hinge 132 will become larger and larger; the advantage of this structural setting is that it can lock or unlock the limit shaft 115 when it is in the limit slot 13a, so that the relative position between the first pivot hinge 131 and the second pivot hinge 132 can be more stable when folded, and will not be naturally unlocked during the process of being sent into the well chamber 200, thereby avoiding the intercepting frame 110 from opening naturally during the insertion, and ensuring the stable and orderly progress of the operation.

[0040] In summary, the utility model provides an interception and protection device, which can realize the assembly of the interception frame in well chambers of different calibers by adjusting the length of the support rod, and the support rod can be adjusted in length so that it can be fully assembled with the inner wall of the well chamber, so that it can jam the inner wall of the well chamber and effectively intercept the workers who are about to be rushed into the downstream pipeline, thereby greatly protecting the lives of the workers.
