Description

Technical Field

[0001] The present invention relates to the technical field of high-end equipment manufacturing, and in particular to an anti-impact interception device. Background Art

[0002] During the operation and maintenance of municipal drainage pipelines, the safety of construction workers needs to be guaranteed. In traditional pipeline operations, water-blocking airbags are often used to block and cut off 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 blockage fails or water comes unexpectedly, workers are very likely to be rushed into the downstream pipeline by the instantaneous water flow, causing unpredictable dangers.

[0003] At present, the recommended practice is often adopted, that is, to add steel mesh as a protective measure in the downstream inspection well. This steel mesh is usually set as a fixed structure, which makes it difficult for the traditional steel mesh to be fully assembled with the inner wall of the well chamber, and the protective effect is greatly reduced. 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; and through the design of the steel mesh, the construction workers will be injured due to the large impact force after being rushed down. Summary of the invention

[0004] In view of the safety deficiencies of the prior art, an object of the present invention is to provide an anti-impact interception device with high safety protection.

[0006] In some embodiments, the protection assembly includes a first protection member and a second protection member; The first protection element is an auxiliary protection; The second protection element is a primary protection element; the trigger component controls the activation of the second protection element.

[0007] In some embodiments, the first protection member includes a stopper and a first spring; The blocking member is installed on one side of the intercepting member, one side of the blocking member is located inside the intercepting member, and the other side of the blocking member is located outside the intercepting member. The first spring is located between one side of the blocking member and the intercepting member, and the first spring applies force to the blocking member to move toward the other side of the blocking member.

[0008] In some embodiments, the second protective member comprises an air bag; The airbag is installed in the blocking member; When the trigger assembly is triggered, the trigger assembly activates the airbag, and the airbag can move to the outside of the blocking member after activation.

[0009] In some embodiments, the drive assembly includes a drive disc and a transmission assembly; The driving disc is located outside the supporting assembly; The transmission assembly is located inside the support assembly; When the driving disk is rotated, the driving disk drives the transmission assembly to transmit, and the transmission assembly drives the support rod to move away from or close to the support assembly.

[0010] In some embodiments, the transmission assembly includes a driving shaft, a driving member, a driven member, and an output shaft; The driving shaft is installed on the supporting assembly, and the driving disc is sleeved on the outer end of the driving shaft. The active member is mounted on the active shaft; The output shaft is mounted on the support rod, and the driven member is mounted on the output shaft; When the driving disk rotates to drive the driving shaft to rotate, the driving shaft drives the active member to rotate, the active member drives the driven member to rotate and then drives the output shaft to rotate, and the output shaft drives the support rod to move away from or close to the support assembly.

[0011] In some embodiments, the trigger assembly includes a trigger switch and a trigger member; The trigger switch is mounted on the support assembly, and the trigger member is connected to the drive disk; When the driving disk rotates to move the support rod away from the supporting assembly, the driving disk moves the trigger member above the trigger switch, and the trigger member can activate the trigger switch, so that the trigger assembly is in a ready-to-trigger state; when the driving disk rotates to move the support rod toward the supporting assembly, the driving disk moves the trigger member out from above the trigger switch, and the trigger switch cannot be activated, so that the trigger assembly is in an untriggerable state.

[0012] In some embodiments, the support assembly includes a mounting plate and a straight rod directed toward the inner wall of the pipe; The transmission assembly is located in the mounting plate and the straight rod, and one end of the support rod is placed in the straight rod.

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 invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

The x-axis arrow direction is referred to as the "right" direction in the following text, the y-axis arrow direction is referred to as the "up" direction in the following text, and the z-axis arrow direction is referred to as the "back" direction in the following text, which is not limited to the actual application of the present application.

[0021] like Figures 1 to 3As shown, this embodiment provides an anti-impact interception device 100, which includes a support assembly 110, a support rod 120, a drive assembly 130, an interception member 140, a protection assembly 150, and a trigger assembly 160. The support rod 120 is installed on the support assembly 110, the support rod 120 points to the inner wall of the pipe 200, and the support rod 120 can move away from or close to the support assembly 110; the drive assembly 130 is installed on the support assembly 110, and is used to drive the support rod 120 to move away from the support assembly 110 so that the support rod 120 is close to the inner wall of the pipe 200, and drive the support rod 120 to move close to the support assembly 110 so that the support rod 120 is away from the inner wall of the pipe 200; the interception member 140 is installed on the support assembly 110 for interception; the protection assembly 150 0 is installed on the interception member 140 to provide anti-collision protection when a person or an object collides with the interception member 140; the trigger assembly 160 is used to start the protection assembly 150; wherein, when the driving assembly 130 drives the support rod 120 to move away from the support assembly 110 to a preset position, the trigger assembly 160 is in a to-be-triggered state and the protection assembly 150 can be triggered; when the driving assembly 130 drives the support rod 120 to move close to the support assembly 110 and move out of the preset position, the trigger assembly 160 is in a non-triggerable state and the protection assembly 150 cannot be started. That is to say, the support assembly 110 moves the support rod 120 away from the support assembly 110 through the driving assembly 130, and the outer end of the support rod 120 is stuck in the interval of the pipe 200. At this time, the support rod 120 and the support assembly 110 are fixed to the pipe 200 and do not separate, which plays a good supporting role. In addition, since the support rod 120 can be pushed away from the support assembly 110, it can be used for pipes 200 of different diameters. The pushing method is manually controlled, so that when it is installed, the support rod 120 will not always be against the pipe 200, which will cause the clamping operation to be difficult. In addition, the support assembly 110 is provided with an intercepting member 140, and the intercepting member 140 is provided with a protective member 150, which can intercept the construction personnel to prevent them from being washed away by water, and prevent the construction personnel from being injured by hard contact with the intercepting member 140, thereby providing a safe construction environment for the construction personnel. When the support rod 120 moves away from the support assembly 110, the trigger assembly 160 is in the starting state. When the support rod 120 is retracted inward, the trigger assembly 160 cannot be triggered. That is, it can provide protection when supporting in the pipeline 200 and prevent the problem of being triggered and started during the transfer process.

[0022] In this embodiment, the protection component 150 includes a first protection member 151 and a second protection member 152; the first protection member 151 is an auxiliary protection; the second protection member 152 is a main protection; the trigger component 160 controls the activation of the second protection member 152. In other words, the cooperation of the first protection member 151 and the second protection member 152 achieves a double protection effect, protecting the safety of construction workers to the greatest extent. Among them, the main protection: after being manually triggered, it actively contacts the human body and has the greatest protection effect on the human body; and the auxiliary protection: when the human body contacts the protection member, it passively protects the human body and has a certain protection effect.

[0023] like Figures 4 to 5 As shown, in this embodiment, the first protective member 151 includes a stopper 151a and a first spring 151b; the stopper 151a is installed on one side of the interception member 140, one side of the stopper 151a is located inside the interception member 140, and the other side of the stopper 151a is located outside the interception member 140, and the first spring 151b is located between one side of the stopper 151a and the interception member 140, and the first spring 151b gives the stopper 151a a force to move toward the other side of the stopper 151a. The first spring 151b is arranged on the inner side of the stopper 151a, and the outer side of the stopper 151a is placed on the outer side of the interception member 140. When the construction personnel come into contact with the stopper 151a, the first spring 151b gives the construction personnel a buffering force through the stopper 151a, thereby achieving a protective effect.

[0024] The second protective member 152 includes an airbag 152a; the airbag 152a is installed in the blocking member 151a, and when the trigger assembly 160 is triggered, for example, the attached Figure 6 After the trigger assembly 160 is triggered, the driving assembly presses down, and the trigger assembly 160 activates the airbag 152a, which can move to the outside of the blocking member 151a after activation. That is, when the trigger assembly 160 is activated, the trigger switch 161 of the trigger assembly 160 is pressed, and the trigger switch 161 can be transmitted to the gas generator of the airbag 152a via a line or signal, so that the gas generator is activated, and the gas quickly fills the airbag 152a, causing the airbag 152a to expand, thereby achieving a protective effect.

[0025] The first protective member 151 and the second protective member 152 are used in combination, that is, the airbag 152a pops out and the first spring 151b buffers to achieve a protective effect; when the second protective member 152 fails to open in time or the second protective member 152 cannot be opened, the first spring 151b can buffer the construction personnel through the blocking member 151a. Among them, the protection of opening the airbag 152a is the main protection, which prevents the construction personnel from being injured as much as possible; and the first protective component 150 is used for auxiliary protection, that is, the protection adopted when the second protective component 150 does not work, which also prevents the construction personnel from being seriously injured.

[0026] like Figure 4 , Figure 6 As shown, in the present embodiment, the trigger assembly 160 includes a trigger switch 161 and a trigger member 162; the trigger switch 161 is installed on the support assembly 110, and the trigger member 162 is connected to the drive disk 131; when the drive disk 131 rotates to make the support rod 120 move away from the support assembly 110 toward the inner wall of the pipeline 200, the drive disk 131 moves the trigger member 162 above the trigger switch 161, and the trigger member 162 can start the trigger switch 161, so that the trigger assembly 160 is in a state to be triggered; when the drive disk 131 rotates to make the support rod 120 move closer to the support assembly 110 and the support rod 120 is away from the inner wall of the pipeline 200, the drive disk 131 moves the trigger member 162 out from above the trigger switch 161, and the trigger switch 161 cannot be started, so that the trigger assembly 160 is in a state that cannot be triggered. That is to say, before use, the trigger member 162 and the trigger switch 161 are in a misaligned state, and the trigger member 162 cannot trigger the trigger switch 161, which can prevent it from being triggered before use, resulting in difficulty in installation and use later. When in use, it is necessary to rotate the drive disk 131 to move the trigger member 162 above the trigger switch 161, so that the trigger switch 161 can be triggered by the trigger member 162, which is convenient for later trigger protection. If the trigger switch 161 in the waiting state is not triggered for use, when it is removed, the waiting state is restored to the unable to trigger state again with the rotation of the drive disk 131, which can be convenient for later use, thereby effectively avoiding one-time use and causing waste of resources.

[0027] In this embodiment, a sleeve rod 163 is provided on one side of the driving disk 131, and the sleeve rod 163 is sleeved on the active shaft 132a. A second spring 164 is provided in the sleeve rod 163, and the second spring 164 contacts the end of the active shaft 132a. The second spring 164 gives the driving disk 131 a force to move outward through the sleeve rod 163; a swivel 165 is sleeved on the outer side of the sleeve rod 163, and the swivel 165 can rotate relative to the sleeve rod 163. The swivel 165 is an annular magnet. When the swivel 165 is not subject to blocking force, the swivel 165 can be adsorbed on the sleeve rod 163 and rotate with the sleeve rod 163. When the swivel 165 is subject to resistance, it can rotate relative to the sleeve rod 163; a support block 166 is fixed on the outer edge of the swivel 165, and the trigger member 162 is installed on the support block 166. The trigger member 162 can rotate to the top of the trigger switch 161 and rotate out of the top of the trigger switch 161 with the driving disk 131. A blocking rod 167 is provided on the support assembly 110. When the trigger member 162 rotates to above the trigger switch 161 along with the driving disk 131, the blocking rod 167 contacts the support block 166, causing the support block 166 and the rotating ring 165 to stop rotating along with the driving disk 131. Similarly, when the trigger member 162 rotates out from above the trigger switch 161 along with the driving disk 131, the blocking rod 167 contacts the other side of the support block 166, causing the support block 166 and the rotating ring 165 to stop rotating along with the driving disk 131.

[0028] When in use, the trigger member 162 rotates with the driving disk 131 to the top of the trigger switch 161. The driving disk 131 only needs to be pressed, and the driving disk 131 drives the rotating ring 165 to move toward the trigger switch 161, so that the trigger switch 161 is triggered. When the support assembly 110 is removed, the trigger member 162 rotates out from the top of the trigger switch 161 with the driving disk 131. Even if the driving disk 131 is pressed, the trigger switch 161 will not be triggered. It is easy to use and will not be triggered when not in use, so it is easy to use again.

[0029] like Figure 3 to Figure 4 As shown, in this embodiment, the driving assembly 130 includes a driving disk 131 and a transmission assembly 132; the driving disk 131 is located outside the support assembly 110; the transmission assembly 132 is located inside the support assembly 110; when the driving disk 131 rotates, the driving disk 131 drives the transmission assembly 132 to transmit, and the transmission assembly 132 drives the support rod 120 to move away from or close to the support assembly. In other words, by simply rotating the driving disk 131, the driving disk 131 can move the support rod 120 inward and outward through the transmission assembly 132, thereby achieving the effect of rapid installation and fixing.

[0030] like Figure 6As shown, in this embodiment, the transmission assembly 132 includes a driving shaft 132a, a driving member 132b, a driven member 132c and an output shaft 132d; the driving shaft 132a is installed on the support assembly 110, the driving disk 131 is sleeved on the outer end of the driving shaft 132a, and the driving member 132b is installed on the driving shaft 132a; the output shaft 132d is installed on the support rod 120, and the driven member 132c is installed on the output shaft 132d; when the driving disk 131 rotates to drive the driving shaft 132a to rotate, the driving shaft 132a drives the driving member 132b to rotate, the driving member 132b drives the driven member 132c to rotate and then drives the output shaft 132d to rotate, and the output shaft 132d drives the support rod 120 to move away from or close to the support assembly. That is to say, by rotating the driving disk 131, the driving disk 131 rotates the active member 132b via the active shaft 132a, and the active member 132b rotates the output shaft 132d via the driven member 132c, thereby moving the support rod 120 away from or close to the support assembly, thereby completing the support and fixation of the support rod 120 or the separation of the support rod 120 and the pipe 200, which is simple to operate and easy to use.

[0031] In this embodiment, the active member 132b and the driven member 132c are bevel gears, and the number of teeth on the active member 132b is greater than the number of teeth on the driven member 132c, so as to ensure that the output shaft 132d rotates quickly, thereby ensuring that the support rod 120 moves quickly away from or close to the support assembly.

[0032] The outer side of one end of the output shaft 132d away from the driving disk 131 is provided with a thread, and the inner side of the support rod 120 is provided with a thread. The output shaft 132d drives the support rod 120 to move away from or close to the support assembly through the thread.

[0033] In this embodiment, the support assembly 110 includes a mounting plate 111 and a straight rod 112 pointing to the inner wall of the pipe 200; the transmission assembly 132 is located in the mounting plate 111 and the straight rod 112, and one end of the support rod 120 is placed in the straight rod 112. By adopting the design of the mounting plate 111 and the straight rod 112, the use of materials is effectively saved, and the weight of the support assembly 110 is further reduced, which is convenient for use and operation.

[0034] In this embodiment, the number of the straight rods 112 is greater than or equal to three, and the angles between two adjacent straight rods 112 are the same; the number of the support rods 120 is the same as the number of the straight rods 112. When the number of the straight rods 112 and the support rods 120 is the same and greater than or equal to three, when the support rods 120 contact the inside of the pipe 200, the support rods 120 contact the inside of the pipe 200 at greater than or equal to three locations, making the installation more secure and preventing the support rods 120 from being detached due to the insecure installation.

[0035] In this embodiment, the anti-impact interception device 100 further includes a stopper 170; the stopper 170 is installed on the stopper 151a, and the stopper 170 positions the airbag 152a in the stopper 151a. The stopper 170 blocks the airbag 152a, so that the airbag 152a is wrapped in the stopper 151a, and the airbag 152a does not slide out of the stopper 151a when the airbag 152a is not in use.

[0036] The limiting member 170 and the blocking member 151 a are fixed by gluing or clamping, so that the limiting member 170 can be ejected in time.

[0037] The material of the limiting member 170 is elastic material, such as rubber, silicone and the like.

[0038] In this embodiment, the intercepting member 140, the blocking member 151a, the limiting member 170 and the airbag 152a are all in an annular shape or a rectangular frame shape, which can increase their contact area and effectively perform interception and protection.

[0039] A clamping member 180 is disposed at one end of the support rod 120 away from the support assembly 110 , so that the support rod 120 can be easily clamped in the pipe 200 when moving outward.

[0040] In summary, the present invention provides an anti-impact interception device 100, when the support rod is moved close to the support assembly, the trigger assembly cannot be triggered and the protection assembly will not be started, which can facilitate the transportation before installation and the operation inside the pipeline; and when the support rod is moved away from the support assembly, the trigger assembly is in a waiting state, so that it can play a protective role after being triggered, and can be easily folded up when not triggered for reuse.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
