Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction protection devices, in particular to a road construction protection device. BACKGROUND

[0002] The road construction protection device is a device for surrounding and isolating the construction site during road construction. It can protect pedestrians and is commonly used in road construction. The common road construction protection device includes a railing, a color steel plate, and a water horse.

[0003] In related technology, a water horse includes a water horse body and two water stop plugs. The water horse body has a water inlet and a water outlet. The water inlet and the water outlet are connected to the inner cavity of the water horse body. The two water stop plugs are inserted into the water inlet and the water outlet. Water or sand is injected into the water horse through the water inlet to increase the weight of the water horse and improve its protection performance. The water or sand in the water horse is discharged through the water outlet, making it easier for workers to move and transfer the water horse.

[0004] When using a water horse at a construction site with high impact resistance requirements, the water horse needs to be placed in the appropriate position first, and then the water horse in the appropriate position is filled with water one by one. This operation is inconvenient and needs to be improved. SUMMARY

[0005] In order to improve the convenience of workers filling water in each water horse, the present application provides a road construction protection device.

[0006] The road construction protection device provided by the present application adopts the following technical scheme:

[0007] A road construction protection device includes a water horse body with an inner cavity. The water horse body has a water inlet. The side wall of the water horse body is provided with a water inlet seat with an inner cavity. The side wall of the water horse body away from the water outlet seat is provided with a water outlet seat with an inner cavity. The inner cavities of the water inlet seat and the water outlet seat are connected to the inner cavity of the water horse body. The water outlet seat is provided with a water inlet pipe connected to the inner cavity of the water outlet seat. The water inlet pipe is provided with a water inlet control assembly for opening and closing the inner cavity of the water inlet pipe. The outer wall of the water inlet seat is provided with a water outlet hole connected to the inner cavity of the water inlet seat. The water outlet seat is provided with a water outlet control assembly for opening and closing the water outlet hole. When the two water horse bodies are connected, the water inlet pipe on the water inlet seat of one water horse body is inserted into the water outlet hole on the water inlet seat of the other water horse body.

[0008] By adopting the technical scheme, when the road construction protection device is installed, one of the protection devices is placed at a suitable position, the water inlet pipe of the other protection device is inserted into the water outlet hole of the placed protection device, and the inner cavity of the water inlet pipe is opened by the water inlet control assembly and the water outlet hole is opened by the water outlet control assembly. In this way, after all the protection devices are placed, water is input into the water inlet of the first placed water horse body, and the water in the water horse body flows into the water inlet pipe through the water outlet hole of the water outlet seat and is input into the water inlet seat of the second placed protection device through the water inlet pipe.

[0009] In this way, water can be input into one protection device, and all the protection devices can be filled with water. Compared with one-by-one water injection, the above structure can effectively improve the convenience of water injection for the staff. Even if the two protection devices are relatively rotated, the water inlet pipe can still be inserted into the water outlet hole.

[0010] Optionally, the water inlet control assembly includes a water inlet steel ball and a water inlet spring, the inner diameter of the water inlet pipe increases in the direction from the water inlet pipe to the water inlet seat, the diameter of the water inlet steel ball is greater than the minimum inner diameter of the water inlet pipe, the water inlet steel ball is slidingly arranged in the water inlet pipe, and the water inlet spring is connected to the water inlet steel ball and drives the water inlet steel ball to close the inner cavity of the water inlet pipe.

[0011] The water outlet control assembly includes a water outlet steel ball and a water outlet spring connected to the water outlet steel ball, the water outlet hole includes a water blocking hole in communication with the inner cavity of the water outlet seat, the hole diameter of the water blocking hole increases in the direction from the water blocking hole to the inner cavity of the water outlet seat, the water outlet steel ball is slidingly arranged in the water blocking hole and the inner cavity of the water outlet seat, the diameter of the water outlet steel ball is greater than the minimum hole diameter of the water blocking hole, and the water outlet spring is used to drive the water outlet steel ball to close the opening of the water blocking hole.

[0012] By adopting the above technical scheme, when the inner cavity of the water inlet pipe is closed, the diameter of the water inlet steel ball is greater than the minimum inner diameter of the water inlet pipe, and the water inlet spring applies force to the water inlet steel ball, so that the water inlet steel ball closes the inner cavity of the water inlet pipe. When the water in the inner cavity of the water inlet seat wants to flow out through the water inlet pipe, the water applies force to the water inlet steel ball, further enhancing the closing effect of the water inlet steel ball on the inner cavity of the water inlet pipe.

[0013] Similarly, when the water blocking hole is closed, the water outlet steel ball and the water outlet spring can effectively close the opening of the water blocking hole.

[0014] In this way, the sealing performance of the inner cavity of the water inlet pipe when closed and the opening of the water outlet hole when closed is effectively maintained.

[0015] Optionally, the water inlet control assembly further comprises a linkage rod and a limiting rod, the linkage rod and the limiting rod both extend along the sliding direction of the water inlet steel ball, one end of the linkage rod is connected to the water inlet steel ball, the other end of the linkage rod extends out of the water inlet pipe, one end of the limiting rod is connected to the water inlet steel ball, and the other end of the limiting rod is used to abut against the cavity wall of the inner cavity of the water inlet seat towards the opening of the water inlet pipe.

[0016] When the limiting rod in the water inlet control assembly on one of the two water horse bodies abuts against the cavity wall of the water inlet seat, there is a gap between the water inlet steel ball and the water inlet pipe, the end of the linkage rod abuts against the water outlet steel ball in the water outlet control assembly on the other water horse body, and there is a gap between the water outlet steel ball and the hole wall of the water outlet hole.

[0017] By adopting the above technical scheme, when the two water horse bodies are connected, first, one of the protection devices is placed in a suitable position, and then the water inlet pipe on the other protection device is inserted into the water outlet hole on the water outlet seat of the other protection device. During the process of inserting the water inlet pipe into the water outlet hole, the linkage rod abuts against the water outlet steel ball. As the water inlet pipe continues to be inserted into the water outlet hole, the linkage rod moves the water inlet steel ball and the limiting rod until the limiting rod abuts against the cavity wall of the water outlet seat. At this time, the water inlet pipe continues to be inserted into the water outlet hole, and the linkage rod pushes the water outlet steel ball to move. In this way, the opening of the inner cavity of the water inlet pipe and the opening of the water outlet hole are opened, so that the water in the water outlet hole can enter the water inlet pipe.

[0018] Through the above structure, the staff only needs to insert the water inlet pipe into the water outlet hole to complete the placement of the second protection device, so as to realize the communication between the water inlet pipe and the water outlet hole, thereby effectively improving the convenience of the staff when installing and placing the protection device. When installing the protection device, after the first protection device is placed in position, the water horse body of the first protection device can be watered, and then the second water horse device is placed. That is, watering and placing the water horse body are realized at the same time, thereby further improving the installation efficiency of the protection device.

[0019] Optionally, the water outlet hole further comprises a sealing hole opened on the side wall of the water outlet seat, the sealing hole is in communication with the water blocking hole, and a sealing ring is arranged on the hole wall of the sealing hole.

[0020] By adopting the above technical scheme, when the water inlet pipe is inserted into the water inlet hole, it is first inserted into the sealing hole and then inserted into the water blocking hole. Since the sealing ring is arranged on the hole wall of the sealing hole, the leakage of water from the gap between the water inlet pipe and the water blocking hole is limited, thereby effectively ensuring the airtightness when the water inlet pipe is in communication with the water inlet hole.

[0021] Optionally, a guide sliding sleeve is arranged on the cavity wall of the inner cavity of the water inlet seat, and the end of the limiting rod is slidingly arranged in the guide sliding sleeve.

[0022] By adopting the technical scheme, the end of the limiting rod is provided with the sliding rod, and the sliding of the water inlet steel ball and the linkage rod plays a guiding sliding role. On the one hand, the water inlet steel ball guarantees the sealing effect of the inner cavity of the water inlet pipe, and on the other hand, the linkage rod is limited from being deflected, which helps the linkage rod to push the water outlet steel ball.

[0023] Optionally, a plurality of water inlet seats are arranged, the number of the water outlet seats is consistent with that of the water inlet seats, and the water inlet seats and the water outlet seats are arranged along the vertical direction.

[0024] By adopting the technical scheme, the plurality of water outlet seats and the plurality of water inlet seats are arranged, so that the plurality of water inlet pipes can be matched with different water outlet holes. The water outlet seats and the water inlet seats are arranged along the vertical direction, so that a large amount of water does not need to be accumulated in the water horse body to reach a certain height, and then water can be input into the next water horse body. When the water reaches a certain height, the lowermost water outlet seat will input the water into the lowermost water inlet seat of the next water horse body, so that a small amount of water can be quickly input into each water horse body, and the water horse body after being placed is not easy to be tilted.

[0025] Optionally, a first water collecting groove, a second water collecting groove and a water passing pipe are arranged in the inner cavity of the water horse body. The inner cavity of the first water collecting groove is communicated with the inner cavities of the water outlet seats, the inner cavity of the second water collecting groove is communicated with the inner cavities of the water inlet seats, the water passing pipe is arranged in an inclined manner, two ends of the water passing pipe are connected to the first water collecting groove and the second water collecting groove respectively, the inner cavity of the water passing pipe is communicated with the inner cavities of the first water collecting groove and the second water collecting groove, and the height of the connecting end of the water passing pipe and the first water collecting groove is less than the height of the connecting end of the water passing pipe and the second water collecting groove.

[0026] By adopting the technical scheme, when the water horse body is filled with water, the water is directly injected into the first water collecting groove, and the water in the first water collecting groove is input into each water outlet seat. Compared with the water storage space in the water horse body, the water storage space in the first water collecting groove is much smaller, so the water level in the first water collecting groove can quickly rise, the water pressure in the first water collecting groove can quickly rise, and the water in the water outlet seat can enter the water inlet seat of the other protective device through the water outlet hole and the water inlet pipe of the other protective device. The water in the water inlet of the other protective device enters the second water collecting groove, the water level in the second water collecting groove quickly rises and enters the first water collecting groove of the other protective device through the water passing pipe, so that the first water collecting groove and the second water collecting groove of each water horse can be filled with water, and the water transmission is facilitated.

[0027] Optionally, the water horse body is provided with a drain pipe, the inner cavity of the drain pipe is communicated with the inner cavity of the water horse body, the bottom wall of the first water collecting groove and the second water collecting groove is provided with a water guide pipe, the inner cavity of the water guide pipe on the first water collecting groove is communicated with the inner cavities of the first water collecting groove and the drain pipe, the inner cavity of the water guide pipe on the second water collecting groove is communicated with the inner cavities of the second water collecting groove and the drain pipe, and the drain pipe is provided with a drain plug which shields the communication positions of the two water guide pipes and the inner cavity of the drain pipe.

[0028] By adopting the above technical scheme, the drain plug is pulled out during drainage, the water in the water horse body is drained through the drain pipe, and the water in the first water collecting groove and the second water collecting groove is drained through different water guide pipes into the drain pipe and then drained through the drain pipe. By such arrangement, on the one hand, the water in the first water collecting groove and the second water collecting groove can be drained, and on the other hand, the communication between the first water collecting groove and the second water collecting groove during use of the protection device is limited.

[0029] In summary, the present application has at least one of the following beneficial technical effects:

[0030] 1. When connecting two adjacent protection devices, the water inlet seat, the water inlet pipe, the water inlet control assembly, the water outlet seat and the water outlet control assembly are used, so that the water inlet pipe only needs to be inserted into the water inlet hole to realize the connection of the two protection devices and the mutual communication of the inner cavities. In this way, all the water horse bodies can be filled with water by water injection to the water horse body, thereby effectively improving the convenience of water injection to the protection devices by the staff.

[0031] 2. By additionally arranging a plurality of water inlet seats and water outlet seats, a small amount of water can be quickly input into each water horse body, so that the water horse body after placement is not easy to be tilted.

[0032] 3. By the first water collecting groove, the second water collecting groove and the water guide pipe, the water can first fill the first water collecting groove and the second water collecting groove, which is helpful for the transmission of water. BRIEF DESCRIPTION OF DRAWINGS

[0051] The implementation principle of the road construction protection device is as follows: when the protection device is installed and placed, one of the protection devices is placed at an adaptive position, then the water inlet plug 111 is opened and water is injected through the water inlet 11. The water flows into the first water collecting groove 13 and accumulates in the first water collecting groove 13, and the water level in the first water collecting groove 13 gradually rises. As the water level in the first water collecting groove 13 gradually rises above the inner cavities of the water outlets 3, the water in the first water collecting groove 13 flows into the inner cavities of the water outlets 3. When one of the protection devices is injected with water, the water inlet pipes 4 of the other protection device are respectively aligned and inserted into the corresponding water outlet holes 31 of the protection device that has been placed, and the linkage rod 53 abuts against the water outlet steel ball 61. As the water inlet pipe 4 is continuously inserted into the water outlet hole 31, the linkage rod 53, the water inlet steel ball 51 and the limiting rod 54 move, a gap is formed between the water inlet steel ball 51 and the inner wall of the water inlet pipe 4, and the limiting rod 54 abuts against the cavity wall of the inner cavity of the water outlet 3. The water inlet pipe 4 is continuously inserted into the water outlet hole 31 until the second protection device is completely placed on the ground, at this time, the water outlet steel ball moves under the action of the limiting rod 54, the water inlet steel ball and the linkage rod 53, so that a gap is formed between the water outlet steel ball and the water blocking hole 312. In this way, the water in the water outlet 3 can enter the water inlet pipe 4 through the water outlet hole 31 and enter the second water collecting groove 14 of the second protection device that has been placed through the water inlet 2. After the water level of the second water collecting groove 14 continuously rises to be flush with the water passage 15, the water in the second water collecting groove 14 flows to the first water collecting groove 13 through the water passage. In this way, the first water collecting groove 13 and the second water collecting groove 14 of each protection device can be filled with water, at this time, if the water injection continues, the water in the first water collecting groove 13 and the second water collecting groove 14 will overflow into the water horse body 1, so that the water horse body 1 is filled with water.

[0052] In this way, the staff only needs to inject water into the first protection device that has been placed, and can place the subsequent protection device at the same time, effectively improving the convenience of injecting water into the protection device and the convenience of installation.

[0053] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
