Description

Technical Field

[0001] This utility model relates to the field of construction protection equipment technology, specifically a construction spray protection device. Background Technology

[0002] The sprinkler protection device for municipal road construction is an important piece of equipment used for dust reduction, cooling and construction site protection during municipal road construction. The sprinkler system pipeline is mainly fixed to the construction fence, which can evenly spray water onto the construction area, forming a barrier between the construction area and the outside world to prevent dust from escaping outside the construction area, effectively reducing dust pollution, improving the construction environment, and also playing a certain role in the maintenance of the construction area.

[0003] Typically, sprinkler protection devices need to be reused. However, when these devices are transported between different construction sites, there is a lack of protection between the devices and the devices themselves. This can easily damage the sprinkler heads and pipes, resulting in a high rate of failure.

[0004] Chinese utility model patent with announcement number CN221761583U, specifically entitled "A Fence for Road Maintenance", includes posts placed at intervals on the road, the lower part of the posts being connected to the ground by expansion nails or casting; a water intake buckle assembly fixed to the upper end of the posts; and a main water pipe laid on the upper end of the posts, the main water pipe passing through the water intake buckle assembly in sequence.

[0005] In the comparative document, the main water pipe, water intake pipe, and sprinkler head structure of the sprinkler system on the fence are all detachably installed on the fence. After construction is completed, the main water pipe, water intake pipe, and sprinkler head can be removed from the fence and transported separately. However, when the main water pipe, water intake pipe, and sprinkler head are removed from the fence for transportation, there is no dedicated transport container for them, and there is still a risk of collision with other construction tools or materials. At the same time, the main water pipe, water intake pipe, and sprinkler head require additional transport space after disassembly, which is not conducive to the space utilization of transport equipment. Furthermore, the installation and disassembly of the main water pipe, water intake pipe, and sprinkler head require additional manpower and resources.

[0006] Based on this, the present invention designs a construction spray protection device to solve the above problems. Utility Model Content

[0007] This invention provides a construction sprinkler protection device to solve the technical problem that sprinkler heads and sprinkler pipes in traditional sprinkler protection devices are easily damaged.

[0008] According to one aspect of the present invention, a construction sprinkler protection device is provided, comprising a bracket, a sprinkler unit mounted on the bracket, and a water supply pipeline for supplying sprinkler water to the sprinkler unit. The water supply pipeline is disposed within the bracket, and a receiving groove is formed on the surface of the bracket. The sprinkler unit is installed and concealed within the receiving groove. An inlet and an outlet are respectively provided on opposite sides of the receiving groove. The inlet is used to connect to the water supply pipeline to introduce sprinkler water into the receiving groove. The sprinkler unit includes a piston block and a sprinkler head. The piston block is slidably disposed within the receiving groove, and the sprinkler head is fixedly disposed on the side of the piston block facing away from the inlet. The piston block is used to move away from the inlet under the pressure of the sprinkler water, so that the sprinkler head extends out of the receiving groove along the outlet. A drain outlet is provided on the piston block along the sliding direction of the piston block, and the drain outlet is used to introduce sprinkler water from the receiving groove into the sprinkler head. A limiting component is provided within the receiving groove to limit the sliding stroke of the piston block within the receiving groove.

[0009] As a further embodiment of this utility model, the limiting component includes a protrusion provided on one side of the water outlet in the receiving groove, the protrusion protruding from the inner surface of the receiving groove.

[0010] As a further embodiment of this utility model, the limiting component includes a first return spring, with the piston block and the inner wall of the receiving groove respectively connected at both ends. The first return spring is used to limit the sliding stroke of the piston block in the receiving groove while applying an elastic force to the piston block, so as to drive the piston block to drive the spray head to hide in the receiving groove.

[0011] As a further embodiment of this utility model, the first reset spring is located on the side of the piston block facing the outlet of the receiving groove.

[0012] As a further embodiment of this utility model, a guide rod is fixedly provided in the receiving groove, and a guide hole is provided on the piston block. The guide rod passes through both the guide hole and the first return spring.

[0013] As a further embodiment of this utility model, a telescopic groove is provided on the side wall of the guide rod, and a slot is provided in the guide hole of the piston block. The slot is used to align the piston block with the telescopic groove when it moves to a preset position away from the water inlet. A limiting member and an elastic reset assembly are provided in the telescopic groove. The elastic reset assembly is used to elastically drive the limiting member to hide in the telescopic groove. A water-guiding channel is provided on the inner side of the telescopic groove, extending towards the water inlet and communicating with the piston cavity. The water-guiding channel is used to introduce the spray water in the piston cavity into the telescopic groove, so that the pressure of the spray water drives the limiting member to extend out of the telescopic groove and engage with the slot.

[0014] As a further embodiment of this utility model, the limiting member includes a piston disc that matches the size of the telescopic groove and a locking block for engaging with the locking slot. A first inner retraction platform is provided on the side of the telescopic groove away from the water channel. The inner hole size of the first inner retraction platform is smaller than the size of the piston disc and larger than the size of the locking block. The first inner retraction platform is used to limit the sliding stroke of the piston disc and allow the locking block to pass through it.

[0015] As a further embodiment of this utility model, the end of the card block away from the piston disc is provided with a guide slope, which is used to contact the edge of the card slot and guide the card slot to move and align with the card block.

[0016] As a further embodiment of this utility model, the elastic reset assembly includes a second reset spring that springs between the first inner retraction platform and the piston disc, the second reset spring being used to reset the piston disc.

[0017] As a further embodiment of this utility model, the bracket is provided with an installation groove, and a piston cylinder is fixedly installed in the installation groove, the receiving groove being the inner cavity of the piston cylinder.

[0018] This utility model has the following beneficial effects:

[0019] 1. This device conceals the spray unit by forming a receiving groove on the support frame, and sets the water supply pipeline that delivers spray water to the spray unit inside the support frame. During the transportation and handling of the support frame, the spray unit and water supply pipeline remain hidden and will not collide with the support frame, other construction tools, or materials. This ensures the safety of the spray unit and water supply pipeline during transportation and handling, effectively extending the service life of the overall device. At the same time, there is no need to disassemble the spray unit and water supply pipeline, effectively improving the installation and disassembly efficiency of the support frame.

[0020] 2. The water supply pipeline connects to the inlet of the receiving tank. The spray water in the water supply pipeline is introduced into the receiving tank through the inlet. The spray unit includes a piston block and a nozzle. The piston block is slidably set in the receiving tank. When spraying is required, the spray water enters the receiving tank after passing through the water supply pipeline and the inlet in sequence. The pressure of the spray water pushes the piston block to move in the receiving tank, so that the nozzle set on the piston block can extend out of the receiving tank, thus obtaining a good spraying working environment. During the spraying operation, the nozzle can automatically extend out of the receiving tank, making the overall device simpler to use.

[0021] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] Please see Figure 1-7 This utility model provides a technical solution: a construction spray protection device, including a bracket 1, a spray unit installed on the bracket 1, and a water supply pipe 2 for supplying spray water to the spray unit. The bracket 1 is installed on the ground to protect the construction area. The water supply pipe 2 is used to connect the spray water source and the spray unit. The spray water from the spray water source is introduced into the spray unit through the water supply pipe 2 and then sprayed out to reduce dust and cool the construction site, while isolating the construction environment from the external environment.

[0034] The water supply pipe 2 is installed inside the bracket 1 so that the water supply pipe 2 is no longer exposed and to prevent the water supply pipe 2 from being damaged during the movement of the bracket 1.

[0035] The support 1 has a receiving groove 3 formed on its surface. The spray unit is installed and hidden in the receiving groove 3. The receiving groove 3 has an inlet 31 and an outlet on opposite sides. The inlet 31 is used to connect the water supply pipe 2 to introduce spray water into the receiving groove 3. The spray unit can be hidden in the receiving groove 3 to protect the spray unit and prevent the spray unit from being bumped during the transportation and movement of the support 1.

[0036] The spray unit includes a piston block 41 and a spray head 42. The piston block 41 is slidably disposed in the receiving groove 3, and the spray head 42 is fixedly disposed on the side of the piston block 41 facing away from the water inlet 31. The piston block 41 is used to move away from the water inlet 31 under the action of spray water pressure, so that the spray head 42 extends out of the receiving groove 3 along the water outlet.

[0037] When the piston block 41 and the spray head 42 are completely concealed within the receiving tank 3, they serve to protect the safety of the spray head 42. When the spray head 42 is needed for spraying operations, the spray water source is connected to the water supply channel, and spray water is introduced into the receiving tank 3 through the water supply channel and the inlet 31. Figure 3 As shown, the spray water enters the receiving tank 3 through the inlet 31, pushing the piston block 41 in the receiving tank 3 to move away from the outlet of the receiving tank 3, so that the spray head 42 on the piston block 41 extends out of the receiving tank from the outlet of the receiving tank 3, so that the spray head 42 obtains a good spray range.

[0038] A drain port 43 is provided on the piston block 41 along the sliding direction of the piston block 41, which passes through the piston block 41. The drain port 43 is used to introduce the spray water in the receiving tank 3 into the spray head 42. The spray water enters the receiving tank 3 through the water inlet 31, pushes the piston block 41 in the receiving tank 3 to move, and causes the spray head 42 to extend out of the receiving tank 3. At the same time, the spray water also enters the spray head 42 through the drain port 43 on the piston block 41, and sprays the spray water out through the spray head 42, thereby achieving the effects of dust reduction and cooling.

[0039] This device hides the spray unit in the receiving tank 3 and the water supply pipe 2 in the bracket 1. During the transportation and handling of the bracket 1, the spray unit can be hidden in the receiving tank 3 to prevent the spray unit from protruding from the surface of the bracket 1. This effectively protects the spray unit and the water supply pipe 2 and prevents the bracket 1 from causing damage to the spray unit and the water supply pipe 2 during transportation and handling, thus ensuring the safety of the spray unit and the water supply pipe.

[0040] Meanwhile, the receiving tank 3 introduces spray water through the water inlet 31. When the spray unit needs to perform spraying operations, spray water can be introduced into the receiving tank 3 through the water inlet 31. The pressure of the spray water pushes the spray unit to move within the receiving tank 3, thereby allowing the spray head 42 in the spray unit to extend out of the receiving tank 3. When performing spraying operations through the spray head 42, the spray head 42 can extend out of the receiving tank 3, providing the spray head 42 with a good spraying working space and not interfering with the spraying range of the spray head 42. The spray head 42 is driven to extend out of the receiving tank 3 by the pressure of the spray water, eliminating the need for manual operation of the spray unit. It is simple and convenient to use. When it is necessary to hide the spray unit inside the receiving tank 3, the spray unit can be manually moved to hide it inside the receiving tank 3.

[0041] Furthermore, a limiting component is provided in the receiving tank 3. The limiting component is used to limit the sliding stroke of the piston block 41 in the receiving tank 3. When the piston block 41 is moved by introducing spray water into the receiving tank 3 through the water inlet 31, the limiting component limits the sliding stroke of the piston block 41 to prevent the piston block 41 from detaching from the receiving tank 3 under the action of the spray water.

[0042] Specifically, such as Figure 3 As shown, the limiting component includes a protrusion 32 provided on one side of the outlet in the receiving tank. The protrusion 32 protrudes from the inner surface of the receiving tank and directly contacts the piston block 41 to limit the piston block 41.

[0043] The limiting component includes a first return spring 44, with the piston block 41 and the inner wall of the receiving groove 3 respectively at both ends. The first return spring 44 is used to limit the sliding stroke of the piston block 41 in the receiving groove 3 while applying an elastic force to the piston block 41 to drive the piston block 41 to drive the spray head 42 to hide in the receiving groove 3.

[0044] During the spraying operation, the spray water pushes the piston block 41, causing the spray head 42 to extend from the receiving groove 3, thus providing the spray head 42 with a good spraying environment. When the piston block 41 moves away from the water inlet 31 under the action of the spray water, the first return spring 44 deforms, storing energy. When the elastic force of the first return spring 44 reaches equilibrium with the pressure of the spray water, or when the first return spring 44 deforms to its limit position, the spray water can no longer drive the piston block 41 to move, thereby achieving a limiting effect. Simultaneously, after the spraying is completed... When the water supply to the receiving tank 3 stops, the pressure on the piston block 41 facing the inlet 31 disappears, and the first return spring 44 starts to drive the piston block 41 to move towards the inlet 31, thereby causing the spray head 42 to be hidden in the receiving tank 3. The spraying operation is completed and the spray head 42 is automatically retracted, reducing the labor intensity of the workers. At the same time, during the transfer and handling of the support 1, the first return spring 44 can keep the spray head 42 hidden in the receiving tank 3, preventing the spray head 42 from extending out of the receiving tank 3 under the action of gravity.

[0045] Specifically, the first return spring 44 is located on the side of the piston block 41 facing the outlet of the receiving tank 3. During the spraying operation, the side of the piston block 41 facing the inlet 31 will directly contact the spray water. By placing the first return spring 44 on the side of the piston block 41 facing the outlet, the first return spring 44 can be prevented from contacting the spray water, thus preventing the first return spring 44 from being immersed in the spray water for a long time and improving the service life of the first return spring 44.

[0046] Specifically, such as Figure 3 As shown, when the first return spring 44 is located on the side of the piston block 41 facing the water outlet, the end of the first return spring 44 away from the piston block 41 can be connected to the protrusion 32.

[0047] Furthermore, a guide rod 5 is fixedly installed in the receiving groove 3, and a guide hole 45 is opened on the piston block 41. The guide rod 5 passes through both the guide hole 45 and the first return spring 44.

[0048] The guide rod 5 limits the first return spring 44 to prevent radial twisting when the first return spring 44 is compressed, thus ensuring the safe use of the first return spring 44. At the same time, the guide rod 5 passes through the piston block 41 and guides the piston block 41. When the piston block 41 is circular, it prevents the piston block 41 from rotating in the receiving groove 3.

[0049] Furthermore, a telescopic groove 51 is provided on the side wall of the guide rod 5, and a slot 46 is provided in the guide hole 45 of the piston block 41. The slot 46 is used to align the piston block 41 with the telescopic groove 51 when it moves to a preset position away from the water inlet 31. A limiting member and an elastic reset component are provided in the telescopic groove 51. The elastic reset component is used to elastically drive the limiting member to be hidden in the telescopic groove 51. A water inlet channel 52 is provided on the inner side of the telescopic groove 51, extending towards the water inlet 31 and communicating with the piston cavity. The water inlet channel 52 is used to introduce the spray water in the piston cavity into the telescopic groove 51 so that the pressure of the spray water drives the limiting member to extend out of the telescopic groove 51 and engage with the slot 46.

[0050] By opening a telescopic groove 51 on the guide rod 5 and setting a limiting member, when the piston block 41 moves to the preset position in the direction away from the water inlet 31, the telescopic groove 51 is aligned with the slot 46 opened in the guide hole 45. The current position of the piston block 41 can be locked by the limiting member and the slot 46, preventing the piston block 41 from moving in the receiving cavity due to unstable water pressure. The stability of the piston block 41 can be guaranteed during spraying operations.

[0051] A water channel 52 is provided inside the telescopic groove 51. The water channel 52 is used to connect the receiving groove 3 and the telescopic groove 51. When the spray water enters the receiving groove 3 and pushes the piston block 41 to move, the spray water can enter the telescopic groove 51 through the water channel 52, thereby driving the limiting member in the telescopic groove 51 to extend out of the telescopic groove 51 and engage with the slot 46. This links the movement of the limiting member with the movement of the piston block 41, making the use of the whole device simpler and requiring no manual intervention.

[0052] Specifically, the limiting component includes a piston disc 53 that matches the size of the telescopic groove 51 and a locking block 54 for engaging with the locking slot 46. A first inner retraction platform 55 is provided on the side of the telescopic groove 51 away from the water channel 52. The inner hole size of the first inner retraction platform 55 is smaller than the size of the piston disc 53 and larger than the size of the locking block 54. The first inner retraction platform 55 is used to limit the sliding stroke of the piston disc 53 and allow the locking block 54 to pass through it.

[0053] like Figure 6 As shown, the piston disc 53 and the telescopic groove 51 are matched in size. When the spray water enters the telescopic groove 51 from the water inlet channel 52, the spray water will push the piston disc 53 to move away from the water inlet channel 52. Under the action of the piston disc 53, the locking block 54 extends out of the telescopic groove 51 and engages with the locking groove 46. In order to prevent the piston disc 53 from coming off the telescopic groove 51, an inner retraction platform is provided at one end of the telescopic groove 51 away from the water inlet channel 52. An inner hole is opened in the middle of the inner retraction platform for the locking block 54 to pass through, ensuring that the telescopic platform will not block the locking block 54 while limiting the piston disc 53.

[0054] In order to prevent the locking block 54 from interfering with the movement of the piston block 41, Figure 7 An example is disclosed in which the connection position between the water inlet channel 52 and the receiving tank 3 is precisely controlled so that the opening of the water inlet channel 52 on the inner wall of the receiving tank 3 is close to the telescopic groove 51. Before the piston block 41 moves to the working position, the opening of the water inlet channel 52 on the inner wall of the receiving tank 3 is separated from the spray water in the receiving tank 3 by the piston block 41. After the piston block 41 moves to the working position, the opening of the water inlet channel 52 on the inner wall of the receiving tank 3 comes into contact with the spray water. The spray water is introduced from the water inlet channel 52 into the telescopic groove 51 to push the piston disc 53 to move. Since the piston block 41 has moved into place at this time, the locking block 54 can directly engage with the locking groove 46 opened in the guide groove when it extends out of the telescopic groove 51 to lock the position of the piston block 41.

[0055] Figures 5-6 Another example is disclosed, in which the end of the card block 54 away from the piston disk 53 is provided with a guide ramp 56, the guide ramp 56 is used to contact the edge of the card slot 46 and guide the card slot 46 to move and align with the card block 54.

[0056] like Figure 6 As shown, the end of the guide slope 56 closest to the inlet 31 is the first end, and the end of the guide slope 56 furthest from the inlet 31 is the second end. The distance from the first end of the guide slope 56 to the piston disc 53 is less than the distance from the second end of the guide slope 56 to the piston disc 53. When the piston block 41 contacts the guide slope 56, pressure is generated towards the inside of the telescopic groove 51. Because the contact area between the piston block 41 and the spray water is larger, the pressure of the spray water on the piston block 41 will be greater. The contact area between the piston disc 53 and the spray water is smaller, and the pressure of the spray water on the piston disc 53 will be less. Therefore, under the pressure of the spray water, the piston block 41 can push the locking block 54 and the piston disc 53 towards the inside of the telescopic groove 51. The piston block 41 is pushed inside the telescopic groove 51, allowing it to pass smoothly through the position of the telescopic groove 51. This aligns the telescopic groove 51 with the slot 46 in the guide hole 45. At this point, the piston block 41's obstruction of the locking block 54 disappears. Under the pressure of the spray water, the locking block 54 will extend out of the telescopic groove 51 again and engage with the slot 46. At this point, there is no need to control the opening position of the water channel 52 on the inner wall of the receiving groove 3. Even if the locking block 54 extends out of the telescopic groove 51 before the piston block 41 moves to the working position, the piston block 41 can contact the guide slope 56 to press the locking block 54 into the telescopic groove 51. The extension of the locking block 54 out of the telescopic groove 51 will not affect the movement of the piston block 41.

[0057] Specifically, the distance from the first end of the guide ramp 56 to the piston disc 53 is not greater than the height of the first inner retraction platform 55, ensuring that the first end of the guide ramp 56 will not protrude from the telescopic groove 51, and ensuring that the piston block 41 can normally contact the guide ramp 56.

[0058] Preferred, such as Figure 6 As shown, the elastic reset assembly includes a second reset spring 57 that is pressed between the first inner retraction platform 55 and the piston disk 53. The second reset spring 57 is used to reset the piston disk 53.

[0059] When the locking block 54 extends out of the telescopic groove 51, the piston disc 53 will compress the second return spring 57, causing the second return spring 57 to store energy. After the spraying operation is completed, the pressure of the spray water on the piston disc 53 disappears, and the second return spring 57 drives the piston disc 53 to reset. The locking block 54 is hidden in the telescopic groove 51. At this time, the locking block 54 is no longer engaged with the locking groove 46. The piston block 41 can be reset to a position close to the water inlet 31 under the action of the first return spring 44, so that the spray head 42 retracts into the receiving groove 3, and the piston disc 53 automatically retracts into the telescopic groove.

[0060] Specifically, such as Figures 1-2 As shown, the bracket 1 has an installation groove, and the piston cylinder 11 is fixedly installed in the installation groove. The receiving groove 3 is the inner cavity of the piston cylinder 11. By opening an installation groove on the bracket 1 and fixing the piston cylinder 11 in the installation groove, the inner cavity of the piston cylinder 11 is the receiving groove 3. The processing of the receiving groove 3 is separated from the bracket 1, which makes the overall production difficulty lower. At the same time, the piston cylinder 11 is a unit design, and the piston cylinder 11 can be replaced when damaged, which makes it more maintainable.

[0061] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
