Description

Technical Field

[0001] This utility model relates to the field of water flow indicator technology, and more specifically to an impact-resistant water flow indicator. Background Technology

[0002] Water flow indicators are mainly used in automatic sprinkler systems. They are installed on the main water supply pipe or horizontal trunking to provide an electrical signal for the water flow in a specific area. This electrical signal can be sent to the electrical control box, but it is usually not used as a control switch to start the fire pump.

[0003] Water flow indicators generally include saddle-type water flow indicators, among which, saddle-type water flow indicators can quickly transmit electrical signals of water flow in a region, facilitating relevant personnel to quickly identify potential hazards {as shown in Publication No.: CN212903246U, A Buffer-type Saddle-type Water Flow Indicator};

[0004] The aforementioned "buffered saddle-type flow indicator" uses a "stabilizing device" to provide instantaneous shock protection for the "swing rod and blade". However, this "stabilizing device" can only be installed in the "mounting base" to support and stabilize the "swing rod and blade", while the "swing rod and blade" are exposed outside the "mounting base". Therefore, there is also the disadvantage that the "swing rod and blade" are not stable when swinging. Utility Model Content

[0005] The purpose of this utility model is to provide an impact-resistant water flow indicator in order to solve the above-mentioned technical problems.

Detailed Implementation

[0023] like Figure 1 As shown, this utility model proposes: an impact-resistant water flow indicator, comprising;

[0024] Mounting base 1 (as shown in the figure, mounting base 1 has an opening that extends through the top and bottom).

[0025] Indicator 2 is fixedly mounted on the top of mounting base 1;

[0026] The oscillating blade 3 is installed at the bottom of the indicator 2 and is located inside the mounting base 1 (i.e., inside the opening). Part of the oscillating blade 3 extends out of the mounting base 1 (used by the indicator 2 for external power control components; when the oscillating blade 3 is impacted by water, i.e., impacted to the left as shown in the figure, it generates information for the indicator 4 and transmits it to the electrical control unit).

[0027] The guide support assembly 4 is fixed between the swing blade 3 and the mounting base 1 to provide guidance and elastic support for the movement of the swing blade 3 (as shown in the figure, one set of guide support assembly 4 is provided; however, multiple sets can also be provided for support).

[0028] To enable the implementation and use of the aforementioned guide support component 4, it is proposed that, for example... Figure 1 As shown, the specific structure and composition of the guide support assembly 4 can be as follows: The guide support assembly 4 includes a first arc-shaped sleeve rod 41 with one end fixed inside the mounting base 1, and a first shaft rod 42 with one end inserted into the other end of the first arc-shaped sleeve rod 41 (the left end of the first arc-shaped sleeve rod 41 is fixed to the mounting base 1, and the right end of the first arc-shaped sleeve rod 41 has a rod cavity for the first shaft rod 42 to be inserted into, as shown in the figure. When the swing blade 3 swings to the left, it is similar to drawing a circle with a radius, that is, the first arc-shaped sleeve rod 41 and the first shaft rod 42 are both arc-shaped rods that coincide with the swing center of the swing blade 3).

[0029] The first universal ball bearing 43 is fixedly mounted outside the first shaft 42, and the first retaining ring 44 is fixed inside the first arc-shaped sleeve 41 to prevent the first universal ball bearing 43 from falling out of the first arc-shaped sleeve 41 (that is, the first universal ball bearing 43 is fixed outside the first shaft 42 and moves inside the first arc-shaped sleeve 41, while the first retaining ring 44 is set at the right end inside the first arc-shaped sleeve 41 to prevent the first universal ball bearing 43 from falling out of the rod cavity of the first arc-shaped sleeve 41).

[0030] The first guide groove 45 is provided inside the first arc-shaped sleeve 41, and the first universal ball 43 rolls in close contact with the first guide groove 45 to provide stability during guiding activities.

[0031] And an elastic element 46 (which can be a spring, etc.) fixed inside the first arc-shaped sleeve 41 to provide elastic support for the movement of the first shaft 42. (As shown in the figure, when the first shaft 42 moves to the left, the elastic element 46 is compressed to provide elastic support and buffer protection.)

[0032] The other end of the first shaft 42 is fixed to the swing blade 3 (as shown in the figure, the right end of the first shaft 42 is fixed to the swing blade 3).

[0033] The first universal ball bearing 43 is provided in multiple sets and is distributed in a ring outside the first shaft 42, and the first guide groove 45 is provided in multiple sets corresponding to the multiple sets of the first universal ball bearing 43, and the multiple sets of the first guide groove 45 are all provided inside the first arc-shaped sleeve 41 (e.g. Figure 1 Two sets of the first universal ball bearings 43 are provided and distributed on the upper and lower sides of the first shaft 42. That is, two sets of the first guide grooves 45 are also provided and respectively located on the upper and lower sides of the first arc-shaped sleeve 41, so that the first universal ball bearings 43 can provide guidance and support respectively, thereby improving the stability during movement.

[0034] It also includes an extension rod 5, which is fixed to the bottom of the mounting base 1 (as shown in the figure, at least one extension rod 5 is provided, with the rod ends facing up and down, fixed to the bottom of the mounting base 1, and located on the left side of the swing blade 3, just like the guide support assembly 4).

[0035] Several sets of guiding components 6 are fixed between the extension rod 5 and the swing blade 3 that extends out of the mounting base 1 to improve the guiding stability of the swing blade 3 (increasing the guide cloth surface can improve the overall position correction effect of the swing blade 3 that extends out of the mounting base 1).

[0036] The guidance component 6 is provided in multiple sets, and is located on the left side of the swing blade 3, just like the guide support component 4 (as shown in the figure, the guidance component 6 is provided in two sets, which are evenly distributed on the left end of the swing blade 3 together with the guide support component 4 mentioned above).

[0037] To implement and use the aforementioned tutoring component 6, it is proposed that, for example... Figure 1As shown, the specific structure and composition of the guidance component 6 can be as follows: The guidance component 6 includes a second arc-shaped sleeve rod 61 with one end fixed to the extension rod 5, a second shaft rod 62 with one end inserted into the other end of the second arc-shaped sleeve rod 61, a second universal ball bearing 63 fixedly mounted on the outside of the second shaft rod 62, a second retaining ring 64 fixed inside the second arc-shaped sleeve rod 61 to prevent the second universal ball bearing 63 from falling out of the second arc-shaped sleeve rod 61, and a second guide groove 65 provided inside the second arc-shaped sleeve rod 61. The second universal ball bearing 63 rolls in close contact with the outside of the second guide groove 65. The other end of the second shaft rod 62 is fixed to the swing blade 3 (also the second shaft rod 62 moves within the second arc-shaped sleeve rod 61 to provide guidance). (As shown in the figure, the right end of the second arc-shaped sleeve rod 61 is fixed to the extension rod 5, and the right end of the second shaft rod 62 is fixed to the swing blade 3).

[0038] The second universal ball bearing 63 is provided in multiple sets and is distributed in a ring outside the second shaft 62. The second guide groove 65 is provided in multiple sets corresponding to the multiple sets of the second universal ball bearing 63. The multiple sets of the second guide groove 65 are all provided inside the second arc-shaped sleeve 61 (according to the above, the activity stability of the second shaft 62 inside the second arc-shaped sleeve 61 is improved, and the stability of the swing blade 3 when deflected is further enhanced).

[0039] Based on the above, the structure of the guide component 6 is the same as that of the guide support component 4, except that the elastic element 46 is missing. At the same time, the arc-shaped circle formed by the second arc-shaped sleeve 61 and the second shaft 62 of the guide component 6 is larger the further away from the deflection center of the swing blade 3.
