Description

Technical Field

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

[0002] During the operation and maintenance of municipal drainage pipelines, it is necessary to ensure the safety of construction workers. In traditional pipeline operations, it is common to use water-blocking airbags for plugging and water interception. Although this method can prevent the impact of upstream water to a certain extent, it lacks direct and effective protection for the workers inside the pipeline. Especially when the plugging of the upstream well fails or unexpected water comes, the personnel are extremely likely to be instantly washed into the downstream pipeline by the water flow, causing unpredictable dangers.

[0003] Currently, the commonly adopted method is to add a steel mesh in the downstream inspection well as a protective measure. This steel mesh is usually set as a fixed structure, making it difficult for the traditional steel mesh to be fully assembled with the inner wall of the well chamber, greatly reducing the protective effect. Moreover, municipal well chambers are mostly cylindrical structures with different sizes, and it is difficult for the steel mesh of this structure to be adapted to well chambers with different diameters, resulting in poor adaptability and practicability, and there are still relatively large safety risks in the actual operation process; also, through the design of the steel mesh, when the construction workers are washed down, the impact force is relatively large, leading to the problem of the construction workers being injured. Summary of the Invention

[0004] Aiming at the deficiencies in safety existing in the prior art, the purpose of the present invention is to provide an anti-impact interception device with high safety protection.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0007] A support assembly;

[0008] A support rod, installed on the support assembly, the support rod pointing to the inner wall of the pipeline, and the support rod being movable away from or close to the support assembly;

[0009] A driving assembly, installed on the support assembly, for driving the support rod to move away from the support assembly so that the support rod approaches the inner wall of the pipeline, and for driving the support rod to move close to the support assembly so that the support rod moves away from the inner wall of the pipeline;

[0011] A protection assembly, installed on the interception member, for providing anti-collision protection when a person or an object collides with the interception member;

[0012] A trigger component for starting the protection component;

[0013] Wherein, after the driving component drives the support rod to move away from the support component to a preset position, the trigger component is in a state of waiting to be triggered and the protection component can be triggered;

[0014] When the driving component drives the support rod to move close to the support component and moves out of the preset position, the trigger component is in a state where it cannot be triggered and the protection component cannot be started.

[0015] In some embodiments, the protection component includes a first protection member and a second protection member;

[0016] The first protection member is auxiliary protection;

[0017] The second protection member is the main protection; the trigger component controls the start of the second protection member.

[0018] In some embodiments, the first protection member includes a blocking member and a first spring;

[0019] The blocking member is installed on one side of the intercepting member. One side of the blocking member is inside the intercepting member, and the other side of the blocking member is outside the intercepting member.

[0020] In some embodiments, the second protection member includes an airbag;

[0021] The airbag is installed inside the blocking member;

[0022] When the trigger component is triggered, the trigger component activates the airbag, and after the airbag is activated, it can move to the outside of the blocking member.

[0023] In some embodiments, the driving component includes a driving disk and a transmission component;

[0024] The driving disk is located outside the support component;

[0025] The transmission component is located inside the support component;

[0026] When the driving disk rotates, the driving disk drives the transmission component to transmit power, and the transmission component drives the support rod to move away from or close to the support component.

[0029] The driving member is installed on the driving shaft;

[0030] The output shaft is installed on the support rod, and the driven member is installed on the output shaft;

[0031] When the driving disk rotates to drive the driving shaft to rotate, the driving shaft drives the driving member to rotate, the driving 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.

[0032] In some embodiments, the triggering assembly includes a trigger switch and a trigger member;

[0033] The trigger switch is installed on the support assembly, and the trigger member is connected to the driving disk;

[0035] In some embodiments, the support assembly includes a mounting disk and a straight rod pointing to the inner wall of the pipeline;

[0036] The transmission assembly is located inside the mounting disk and the straight rod, and one end of the support rod is placed inside the straight rod.

[0037] In some embodiments, the number of the straight rods is greater than or equal to three, and the included angles between adjacent two straight rods are the same;

[0040] The limiting member is installed on the blocking member, and the limiting member makes the airbag located inside the blocking member.

[0041] The beneficial effects of the present invention are as follows: when the support rod approaches the support assembly and moves away from the inner wall of the pipeline, the triggering assembly cannot be triggered, and the protection assembly will not be activated, which facilitates handling before installation and operation inside the pipeline; when the support rod moves away from the support assembly and moves towards the inner wall of the pipeline, the triggering assembly is in a state of waiting to be triggered, so that it can provide protection after being triggered and can be easily retracted when not triggered for reuse.

[0060] Such as Figures 1 to 3As shown in the figure, this embodiment provides an impact-proof 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 pipeline 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 approaches the inner wall of the pipeline 200, and to drive the support rod 120 to move close to the support assembly 110 so that the support rod 120 moves away from the inner wall of the pipeline 200; the interception member 140 is installed on the support assembly 110 and is used for interception; the protection assembly 150 is installed on the interception member 140 and is used 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 drive 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 state of waiting to be triggered and the protection assembly 150 can be triggered; when the drive assembly 130 drives the support rod 120 to move close to the support assembly 110 and moves out of the preset position, the trigger assembly 160 is in a state where it cannot be triggered and the protection assembly 150 cannot be started. That is to say, the support assembly 110 drives the support rod 120 to move away from the support assembly 110 through the drive assembly 130, and the outer end of the support rod 120 is stuck in the interval of the pipeline 200. At this time, the support rod 120 and the support assembly 110 are fixed to the pipeline 200 and do not separate, playing a good supporting role. And because the support rod 120 can be pushed to move away from the support assembly 110, it can thus be applicable to pipelines 200 of different diameters. And the pushing method is manually controlled, so that during installation, the clamping operation will not be difficult due to the support rod 120 always pressing against the pipeline 200. Also, an interception member 140 is provided on the support assembly 110, and a protection assembly 150 is provided on the interception member 140, which can prevent construction workers from being washed away by water during interception construction, and prevent construction workers from being injured due to hard contact with the interception member 140, providing a safe construction environment for construction workers. And when the support rod 120 moves away from the support assembly 110, the trigger assembly 160 is in a triggered state, and 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 can also prevent the problem of being triggered and started during the transfer process.

[0061] In this embodiment, the protection component 150 includes a first protection member 151 and a second protection member 152; the first protection member 151 provides auxiliary protection; the second protection member 152 provides main protection; the trigger component 160 controls the activation of the second protection member 152. That is to say, the cooperation of the first protection member 151 and the second protection member 152 achieves a double protection effect, maximizing the safety of construction workers. Among them, main protection: after being manually triggered, it actively contacts the human body and provides the maximum protection effect on the human body; while auxiliary protection: when the human body contacts the protection member, it passively provides protection to the human body and provides a certain degree of protection effect.

[0062] As Figures 4 to 5 shown, in this embodiment, the first protection member 151 includes a stopper 151a and a first spring 151b; the stopper 151a is installed on one side of the interceptor 140, one side of the stopper 151a is inside the interceptor 140, the other side of the stopper 151a is outside the interceptor 140, and the first spring 151b is located between one side of the stopper 151a and the interceptor 140, and the first spring 151b gives the stopper 151a a force to move towards the other side of the stopper 151a. By arranging the first spring 151b inside the stopper 151a and placing the outside of the stopper 151a outside the interceptor 140, when a construction worker contacts the stopper 151a, the first spring 151b gives the construction worker a buffering force through the stopper 151a, achieving a protection effect.

[0063] The second protection member 152 includes an airbag 152a; the airbag 152a is installed inside the stopper 151a. When the trigger component 160 is triggered, for example, Figure 6 after the trigger component 160 is triggered and pressed by the driving component as shown in the figure, the trigger component 160 activates the airbag 152a, and after the airbag 152a is activated, it can move to the outside of the stopper 151a. That is to say, when the trigger component 160 is activated, the trigger switch 161 of the trigger component 160 is pressed, and the trigger switch 161 can transmit a signal to the gas generator of the airbag 152a through a circuit or signal, causing the gas generator to be activated, and the gas quickly fills the airbag 152a, causing the airbag 152a to expand, thereby achieving a protection effect.

[0064] By using the first protective member 151 and the second protective member 152 in combination, the airbag 152a can be ejected and the first spring 151b can buffer together to achieve a protective effect; also, when the second protective member 152 fails to open in time or cannot be opened, the first spring 151b can buffer the construction workers through the stopper 151a. Among them, the protection with the opening of the airbag 152a is the main protection to prevent the construction workers 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 fails to work, which can also prevent the construction workers from being seriously injured.

[0065] As Figure 4 , Figure 6 shown, in this embodiment, the triggering component 160 includes a trigger switch 161 and a trigger member 162; the trigger switch 161 is installed on the support component 110, and the trigger member 162 is connected to the driving disk 131; when the driving disk 131 rotates to make the support rod 120 move along the direction away from the support component 110 towards the inner wall of the pipeline 200, the driving disk 131 moves the trigger member 162 above the trigger switch 161, and the trigger member 162 can activate the trigger switch 161 to make the triggering component 160 in a state of waiting to be triggered; when the driving disk 131 rotates to make the support rod 120 move closer to the support component 110 and the support rod 120 moves away from the inner wall of the pipeline 200, the driving disk 131 moves the trigger member 162 out of the upper part of the trigger switch 161, and the trigger switch 161 cannot be activated, making the triggering component 160 in a state of being unable to 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 and causing difficulties in installation and use in the later stage. When in use, it is necessary to rotate the driving 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 triggering of the protection. If the trigger switch 161 in the state of waiting to be triggered is not triggered during use, during removal, the state of waiting to be triggered will return to the state of being unable to be triggered again as the driving disk 131 rotates, which can facilitate later use and effectively avoid one-time use and waste of resources.

[0066] In this embodiment, a sleeve rod 163 is provided on one side of the driving disk 131. The sleeve rod 163 is sleeved on the driving shaft 132a. A second spring 164 is provided inside the sleeve rod 163. The second spring 164 contacts the end of the driving shaft 132a. The second spring 164 gives the driving disk 131 a force to move outward through the sleeve rod 163. A rotating ring 165 is sleeved outside the sleeve rod 163. The rotating ring 165 can rotate relative to the sleeve rod 163. The rotating ring 165 is an annular magnet. When the rotating ring 165 is not blocked, the rotating ring 165 can be adsorbed on the sleeve rod 163 and rotate with the sleeve rod 163. When the rotating ring 165 is blocked, it can rotate relative to the sleeve rod 163. A support block 166 is fixed on the outer edge of the rotating ring 165. The trigger 162 is installed on the support block 166. The trigger 162 can rotate with the driving disk 131 to above the trigger switch 161 and out of the upper side of the trigger switch 161. A stop rod 167 is provided on the support assembly 110. When the trigger 162 rotates with the driving disk 131 to above the trigger switch 161, the stop rod 167 contacts the support block 166, causing the support block 166 and the rotating ring 165 to stop rotating with the driving disk 131. Similarly, when the trigger 162 rotates with the driving disk 131 out of the upper side of the trigger switch 161, the stop rod 167 contacts the other side of the support block 166, causing the support block 166 and the rotating ring 165 to stop rotating with the driving disk 131.

[0067] During use, when the trigger 162 rotates with the driving disk 131 to above the trigger switch 161, simply pressing the driving disk 131 will drive the rotating ring 165 to move towards the trigger switch 161 through the driving disk 131, triggering the trigger switch 161. When the support assembly 110 is removed, the trigger 162 rotates with the driving disk 131 out of the upper side of the trigger switch 161. Even if the driving disk 131 is pressed, the trigger switch 161 will not be triggered. It is convenient to use and will not be triggered when not in use, facilitating reuse.

[0068] As Figures 3 to 4 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 power, and the transmission assembly 132 drives the support rod 120 to move away from or close to the support assembly. That is to say, by simply rotating the driving disk 131, the driving disk 131 can move the support rod 120 in and out through the transmission assembly 132, thereby achieving the effect of quick installation and fixation.

[0069] As 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 causes the driving member 132b to rotate through the driving shaft 132a, and the driving member 132b causes the output shaft 132d to rotate through the driven member 132c, thereby causing the support rod 120 to move away from or close to the support assembly, thus completing the support and fixation of the support rod 120 or the separation of the support rod 120 from the pipeline 200. The operation is simple and convenient to use.

[0070] In this embodiment, the driving member 132b and the driven member 132c are bevel gears, and the number of teeth on the driving member 132b is greater than the number of teeth on the driven member 132c to ensure the rapid rotation of the output shaft 132d, and thus ensure the rapid movement of the support rod 120 away from or close to the support assembly.

[0071] A thread is provided on the outer side of the end of the output shaft 132d away from the driving disk 131, and a thread is provided inside the support rod 120. The output shaft 132d drives the support rod 120 to move away from or close to the support assembly through the thread.

[0072] In this embodiment, the support assembly 110 includes a mounting disk 111 and a straight rod 112 pointing to the inner wall of the pipeline 200; the transmission assembly 132 is located inside the mounting disk 111 and the straight rod 112, and one end of the support rod 120 is placed inside the straight rod 112. By adopting the design of the mounting disk 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.

[0073] In this embodiment, the number of the straight rods 112 is greater than or equal to three, and the included angles between adjacent two straight rods 112 are the same; the number of the support rods 120 is the same as the number of the straight rods 112. By adopting the same number of straight rods 112 and support rods 120, both being greater than or equal to three, when the support rod 120 contacts the inside of the pipeline 200, the contact positions where the support rod 120 contacts the inside of the pipeline 200 are greater than or equal to three, making its installation more firm and preventing the problem of the support rod 120 becoming loose and detaching.

[0074] In this embodiment, the impact-proof interception device 100 further includes a limiting member 170; the limiting member 170 is installed on the blocking member 151a, and the limiting member 170 positions the airbag 152a within the blocking member 151a. With the blocking of the limiting member 170, the airbag 152a is wrapped within the blocking member 151a, ensuring that when the airbag 152a is not in use, it will not slide out of the blocking member 151a.

[0075] The limiting member 170 is fixed to the blocking member 151a by gluing or snap-fitting, facilitating the timely ejection of the limiting member 170.

[0076] The material of the limiting member 170 is an elastic material, such as rubber, silicone, etc.

[0077] In this embodiment, the interception member 140, the blocking member 151a, the limiting member 170, and the airbag 152a are all annular or rectangular frame-shaped, enabling a larger contact area and effectively performing interception and protection.

[0078] A clamping member 180 is provided at one end of the support rod 120 away from the support assembly 110, facilitating the clamping of the support rod 120 within the pipeline 200 when the support rod 120 moves outward.

[0079] In summary, the present invention provides an impact-proof interception device 100. When the support rod moves closer to the support assembly, the trigger assembly cannot be triggered, and the protection assembly will not be activated, facilitating handling before installation and operation within the pipeline. When the support rod moves away from the support assembly, the trigger assembly is in a state of being ready to be triggered, enabling it to provide protection after being triggered and being easily retracted for reuse when not triggered.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
