Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of dam panels of hydropower stations, in particular to a maintenance device for dam panels of hydropower stations. Background Art

[0002] At present, a hydropower station dam panel maintenance device is usually used to maintain the dam panel (ie, spraying).

[0003] In the existing technology, the utility model patent "A water supply structure for maintenance of dam panels of a hydropower station" with authorization announcement number CN207775887U discloses maintenance components such as a main water valve, a water inlet pipe, a spray pipe, a first electric ball valve, a second electric ball valve, an external sprinkler, and a power box. The maintenance (i.e., spraying) of the dam panel is achieved by using the above components in combination.

[0004] However, when the above-mentioned maintenance device is used to maintain the dam panel, since a water inlet pipe, a sprinkler pipe, and a pair of electric ball valves are set on the dam panel, the external sprinklers at both ends of the sprinkler pipe can only achieve local maintenance of the dam panel. For example, the area beyond the spraying radius of the sprinkler cannot be maintained, and the position where the external sprinkler is not installed cannot be maintained.

[0005] Therefore, there is an urgent need for a maintenance device for the dam panels of a hydropower station, which can achieve comprehensive maintenance of the dam panels. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a maintenance device for a hydropower station dam panel, which can achieve comprehensive maintenance of the dam panel by setting the position and number of sprinkler heads on the dam panel.

[0007] The utility model provides a maintenance device for a dam panel of a hydropower station, characterized in that: N maintenance mechanisms are used to maintain the dam panel, where N is a positive integer not less than 2, and each maintenance mechanism includes a water supply component, a diversion component fixedly connected to the water supply component, and a spray component fixedly connected to the diversion component;

[0008] The diversion assembly includes a main water pipe and a secondary water pipe, wherein the end of the main water pipe is connected to the middle of the secondary water pipe and divides the secondary water pipe into two left and right parts;

[0009] The spray assembly includes a plurality of spray heads with a spray radius of Rm arranged at intervals on the left and right parts of the auxiliary water pipe, and the spray heads are 360° automatic rotating spray heads;

[0010] The distance between the sprinkler head at the left end of the auxiliary water pipe of the maintenance mechanism arranged at the top of the dam panel and the first vertex is less than the sprinkler radius Rm, the distance between the sprinkler head at the right end of the auxiliary water pipe of the maintenance mechanism arranged at the top of the dam panel and the second vertex is less than the sprinkler radius Rm, and the distance between the sprinkler heads between the left end and the right end of the auxiliary water pipe of the maintenance mechanism arranged at the top of the dam panel is less than or equal to the sprinkler radius Rm.

[0011] The above-mentioned maintenance device for the dam panel of a hydropower station is characterized in that: among the N maintenance mechanisms, the length of the main water pipe of the Nth maintenance mechanism is greater than the length of the main water pipe of the N-1th maintenance mechanism, the secondary water pipe of the Nth maintenance mechanism is arranged below the secondary water pipe of the N-1th maintenance mechanism, and the multiple sprinkler heads of the Nth maintenance mechanism and the multiple sprinkler heads of the N-1th maintenance mechanism are arranged in a vertically aligned manner, or in a vertically staggered manner.

[0012] The above-mentioned maintenance device for the dam panel of a hydropower station is characterized in that the vertical staggered method includes the sprinkler head of the Nth maintenance mechanism being arranged on the center line of two adjacent sprinkler heads of the N-1th maintenance mechanism in the vertical direction.

[0013] The above-mentioned maintenance device for the dam panel of a hydropower station is characterized in that the diversion component also includes a pair of diversion water valves symmetrically arranged on the left and right parts of the auxiliary water pipe for controlling diversion.

[0014] The above-mentioned maintenance device for the dam panel of a hydropower station is characterized in that the water supply component includes a water tank, a water pump arranged in the water tank for pumping water out of the water tank, a water valve arranged on the water tank for controlling the power on and off of the water pump, and a power supply arranged on the water tank for powering the water pump.

[0015] The beneficial effect reasoning analysis is as follows:

[0016] In the prior art, since only one water inlet pipe, one sprinkler pipe, and a pair of electric ball valves are provided on the dam panel, the external sprinklers at both ends of the sprinkler pipe can only achieve local maintenance of the dam panel. For example, areas beyond the spraying radius of the sprinkler cannot be maintained, and locations where no external sprinklers are provided cannot be maintained either.

[0017] In the technical solution of the present invention, first, the water supply assembly in the maintenance mechanism can provide water for maintaining the dam panels. Second, the water provided by the water supply assembly can flow through the diversion assembly. Third, multiple sprinkler heads installed on the auxiliary water pipe can spray the water flowing through the auxiliary water pipe onto the dam panels within a spraying area with a spray radius Rm, centered around each sprinkler head, thereby achieving maintenance of the dam panels.

[0018] On the one hand, regarding the maintenance mechanism located at the top of the dam panel, firstly, precisely because the distance between the sprinkler head at the left end of the auxiliary water pipe and the first vertex at the upper left corner of the dam panel is less than the spray radius Rm, the sprinkler head can fully maintain the upper left corner of the dam panel. Secondly, precisely because the distance between the sprinkler head at the right end of the auxiliary water pipe and the second vertex at the upper right corner of the dam panel is also less than the spray radius Rm, the sprinkler head can fully maintain the upper right corner of the dam panel. Thirdly, precisely because the distances between the multiple sprinkler heads spaced apart on the auxiliary water pipe are all less than or equal to the spray radius Rm, the top of the dam panel slope can be fully maintained.

[0019] This avoids the situation in the prior art whereby only a pair of external sprinklers are provided to perform local maintenance on the dam panel, i.e., areas beyond the spraying radius of the sprinklers cannot be maintained, and locations where no external sprinklers are provided cannot be maintained either.

[0020] On the other hand, for the remaining N-1 maintenance mechanisms, due to the slope of the dam panels, the water sprayed by the sprinklers can flow downward under the action of gravity, completing the maintenance of the dam panels. In other words, installing a single maintenance mechanism on the dam panel can achieve comprehensive maintenance of the dam panel. To shorten maintenance time, multiple maintenance mechanisms can be installed. When multiple maintenance mechanisms are operating simultaneously, the sprinklers of each maintenance mechanism can spray their corresponding areas, as long as the dam panel is moistened, thus greatly shortening maintenance time.

[0021] This avoids the situation in the prior art where only one set of maintenance mechanisms is provided, resulting in a long maintenance time.

[0022] In summary, the technical solution of the present invention can not only achieve comprehensive maintenance of the dam panels, but also greatly shorten the maintenance time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention, that is, the features of the embodiments, can be combined with each other. The present invention will be described in detail below with reference to the embodiments and in conjunction with the accompanying drawings.

[0031] In the prior art, since a water inlet pipe, a sprinkler pipe, and a pair of electric ball valves are installed on the dam panel, the external sprinklers at both ends of the sprinkler pipe can only achieve local maintenance of the dam panel. For example, areas beyond the sprinkler's spraying radius cannot be maintained, and locations where no external sprinklers are installed cannot be maintained either.

[0032] Based on this, the utility model provides a maintenance device for a hydropower station dam panel, which can achieve comprehensive maintenance of the dam panel by setting the position and number of sprinkler heads on the dam panel.

[0033] Figure 1 This is a schematic diagram of the three-dimensional structure of a maintenance device for a hydropower station dam panel provided by the utility model. Figure 2 for Figure 1 Schematic diagram of the vertical staggered arrangement of the Nth sprinkler head and the N-1th sprinkler head.

[0034] See also Figure 1 The dam panel includes a first vertex 1 at the upper left corner and a second vertex 2 at the upper right corner. The utility model provides a maintenance device for a hydropower station dam panel, comprising: N maintenance mechanisms for maintaining the dam panel, wherein N is a positive integer not less than 2, and each maintenance mechanism includes a water supply component, a diversion component fixedly connected to the water supply component, and a spray component fixedly connected to the diversion component;

[0035] The diversion assembly includes a main water pipe 3 and a secondary water pipe 4. The end of the main water pipe 3 is connected to the middle of the secondary water pipe 4 and divides the secondary water pipe 4 into two parts, the left and the right.

[0036] The spray assembly includes a plurality of spray heads 5 with a spray radius of Rm, which are spaced apart on the left and right parts of the auxiliary water pipe 4. The spray heads are 360° automatic rotating spray heads.

[0037] The distance between the sprinkler head 5 at the left end of the auxiliary water pipe 4 of the maintenance mechanism at the top of the dam panel and the first vertex 1 is less than the sprinkler radius Rm, the distance between the sprinkler head 5 at the right end of the auxiliary water pipe 4 of the maintenance mechanism at the top of the dam panel and the second vertex 2 is less than the sprinkler radius Rm, and the distance between the sprinkler heads 5 between the left end and the right end of the auxiliary water pipe 4 of the maintenance mechanism at the top of the dam panel is less than or equal to the sprinkler radius Rm.

[0038] The main water pipe 3 may be a polytetrafluoroethylene spring tube.

[0039] The auxiliary water pipe 4 can be a polypropylene plastic pipe with an inner diameter of 100 mm (ie DN100PPR).

[0040] The sprinkler head 5 is fixedly mounted on the outer surface of the auxiliary water pipe 4. For example, the connection between the two can be threaded or clamped, ensuring that the sprinkler head 5 can spray the water in the auxiliary water pipe 4 to a spraying area with the sprinkler head 5 as the center and the spraying radius Rm of the sprinkler head 5 as the spraying area.

[0041] In specific implementation, the water supply assembly first delivers water to the main water pipe 3. Next, the water is split from the main water pipe 3 into the left and right sections of the secondary water pipe 4. Third, the water flows from the secondary water pipe 4 to the various sprinkler heads 5. The sprinkler heads 5 can spray the water within an area with a spray radius Rm, centered around the sprinkler head 5.

[0042] It is understood that the spray head is a 360° automatic rotating spray head, that is, the spraying area is the center area of ​​the circle. The value of the spray radius Rm can be specifically set according to actual conditions, for example, it can be 3m.

[0043] The beneficial effect reasoning analysis is as follows:

[0044] In the prior art, since only one water inlet pipe, one sprinkler pipe, and a pair of electric ball valves are provided on the dam panel, the external sprinklers at both ends of the sprinkler pipe can only achieve local maintenance of the dam panel. For example, areas beyond the spraying radius of the sprinkler cannot be maintained, and locations where no external sprinklers are provided cannot be maintained either.

[0045] In the technical solution of the present invention, first, the water supply assembly within the maintenance mechanism provides water for maintaining the dam panels. Second, the water provided by the water supply assembly flows through the diversion assembly (specifically, the main water pipe 3 and the auxiliary water pipe 4). Third, multiple spray heads 5 installed on the auxiliary water pipe 4 spray the water flowing through the auxiliary water pipe 4 onto the dam panels within a spraying area with a spray radius Rm, centered around each spray head 5, thereby maintaining the dam panels.

[0046] On the one hand, regarding the maintenance mechanism located at the top of the dam panel, firstly, precisely because the distance between the sprinkler head 5 located at the left end of the auxiliary water pipe 4 and the first vertex 1 at the upper left corner of the dam panel is less than the spray radius Rm, the sprinkler head 5 can fully maintain (i.e., spray) the upper left corner of the dam panel. Secondly, precisely because the distance between the sprinkler head 5 located at the right end of the auxiliary water pipe 4 and the second vertex 2 at the upper right corner of the dam panel is also less than the spray radius Rm, the sprinkler head 5 can fully maintain (i.e., spray) the upper right corner of the dam panel. Thirdly, precisely because the distances between the multiple sprinkler heads 5 spaced apart on the auxiliary water pipe 4 are all less than or equal to the spray radius Rm, the top of the dam panel slope (or dam crest) can be fully maintained (i.e., sprayed).

[0047] This avoids the situation in the prior art whereby only a pair of external sprinklers are provided to perform local maintenance on the dam panel, i.e., areas beyond the spraying radius of the sprinklers cannot be maintained, and locations where no external sprinklers are provided cannot be maintained either.

[0048] On the other hand, for the remaining N-1 maintenance mechanisms, since the dam panel exhibits a certain slope, the water sprayed by the sprinkler head 5 can flow downward under the action of gravity, completing the maintenance of the dam panel. In other words, installing a single maintenance mechanism on the dam panel can achieve comprehensive maintenance of the dam panel. To shorten the maintenance time, multiple maintenance mechanisms can be installed. When multiple maintenance mechanisms are operating simultaneously, the sprinkler head of each maintenance mechanism can spray its corresponding area, as long as the dam panel is moistened, thus significantly shortening the maintenance time.

[0049] This avoids the situation in the prior art where only one set of maintenance mechanisms is provided, resulting in a long maintenance time.

[0050] In summary, the technical solution of the present invention can not only achieve comprehensive maintenance of the dam panels, but also greatly shorten the maintenance time.

[0051] In the embodiment described above, a maintenance device for a dam panel of a hydropower station is introduced. In another embodiment of the present invention, a specific arrangement of the sprinkler heads of two adjacent maintenance mechanisms is introduced.

[0052] For example, among N maintenance mechanisms, the length of the main water pipe 3 of the Nth maintenance mechanism is greater than the length of the main water pipe 3 of the N-1th maintenance mechanism, the auxiliary water pipe 4 of the Nth maintenance mechanism is arranged below the auxiliary water pipe 4 of the N-1th maintenance mechanism, and the multiple sprinkler heads 5 of the Nth maintenance mechanism and the multiple sprinkler heads 5 of the N-1th maintenance mechanism are arranged in a vertically aligned manner, or in a vertically staggered manner.

[0053] It can be understood that the larger the serial number of the maintenance organization, the longer the corresponding main water pipe, the lower the vertical position of the corresponding auxiliary water pipe on the dam panel, and the sprinkler head set on the auxiliary water pipe has the same horizontal position as the corresponding auxiliary water pipe on the dam panel (that is, both are on the same horizontal line).

[0054] In the specific implementation, combined with Figure 1 and Figure 2 , you can follow Figure 1 or Figure 2 The layout method is to set the sprinkler heads of two adjacent maintenance mechanisms on the dam panel.

[0055] In the embodiment described above, the specific arrangement of the spray heads of two adjacent maintenance mechanisms is introduced. In another embodiment of the present invention, the specific arrangement structure of the spray heads of two adjacent maintenance mechanisms in a vertically staggered manner is introduced.

[0056] For example, see Figure 2 The vertical staggered manner includes that the sprinkler head 5 of the Nth maintenance mechanism is arranged on the center line of two adjacent sprinkler heads 5 of the N-1th maintenance mechanism in the vertical direction.

[0057] In the specific implementation, since the first maintenance mechanism can realize comprehensive maintenance of the dam panel, the sprinkler heads of the remaining N-1 maintenance mechanisms can be set arbitrarily when staggered. The center line setting method provided by the utility model is an optimal setting method, which can be set according to actual conditions.

[0058] In the embodiment described above, the specific arrangement structure of the sprinkler heads of two adjacent maintenance mechanisms being arranged vertically in an interlaced manner is introduced. In another embodiment of the present invention, a diverter valve is introduced which is arranged on the auxiliary water pipe to control the diversion of water flow to the left and right.

[0059] See also Figure 1 For example, the diversion assembly also includes a pair of diversion valves 6 symmetrically arranged on the left and right parts of the auxiliary water pipe 4 for controlling diversion.

[0060] In the specific implementation, when the water supply component supplies water to the main water pipe 3, the state of the diversion valve 6 can be controlled (for example, open or closed) to control whether the water flow in the main water pipe 3 is diverted to the left and right ends of the secondary water pipe 4, thereby realizing artificial control of the diversion.

[0061] In the embodiment described above, a diverter valve is provided on the auxiliary water pipe to control the diversion of water flow to the left and right. In another embodiment of the present invention, a specific structure of a water supply assembly is described.

[0062] See also Figure 1 The water supply assembly includes a water tank 7, a water pump 8 arranged in the water tank 7 for pumping water out of the water tank 7, a water valve 9 arranged on the water tank 7 for controlling the power on and off of the water pump 8, and a power supply 10 arranged on the water tank 7 for supplying power to the water pump 8.

[0063] The water valve 9 can be a time-controlled switch. The time-controlled switch can be set to multiple groups of curing times to achieve the curing of the dam panels. For example, 16 groups of curing times can be set, that is, the dam panels are cured 16 times in one curing cycle.

[0064] In a specific implementation, the power supply 10 supplies power to the water pump 8 to pump water. After the water valve 9 is closed, the water pump 8 begins to pump water from the water tank 7 into the main water pipe 3. It is understood that the water pump 8 can ensure that the water flowing into the main water pipe 3 has sufficient pressure until the water flows through the sprinkler head 5 and is sprayed to the surrounding area.

[0065] Optionally, when the water supply assembly is set on the top of the dam and the main water pipe 3 is set on the dam surface, under the action of gravity, when the water valve 9 is closed, the water flow in the water tank 7 can flow directly downward to the main water pipe 3 under the action of gravity, that is, a water pump 8 can be selectively set.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
