Technical Field
[0001] The utility model relates to the field of fire fighting equipment, in particular to a water level display device for a fire fighting pool. Background Art
[0002] A fire water tank is a specially built water storage facility designed to provide water for fixed or mobile fire pumps. Fire water tanks are usually used in situations where the municipal water supply network or household inlet pipes cannot meet the design flow requirements of fire water supply inside and outside the building, such as when there is only one household pipe, the design flow of the outdoor fire hydrant exceeds 20 liters / second, the building height exceeds 50 meters, or the municipal fire water supply design flow is insufficient; in these cases, a fire water tank must be set up to ensure that the fire water demand is met.
[0003] An underground fire water pool is a type of fire water pool, which is usually located underground around buildings or places to provide fire water in emergency situations. The advantages of an underground fire water pool are that it does not occupy surface space, does not affect the appearance of buildings, protects water sources from natural and man-made damage, and provides reliable fire water. As underground fire water pools are buried underground for a long time and are in an environment that is more easily exposed to water, ordinary electronic detection equipment is prone to damage. At the same time, due to the location of the underground fire water pool, it is more difficult for staff to inspect and repair it. Generally, the inspection process requires a large amount of time and labor costs. For this reason, a water level display device for a fire pool is proposed, which can ensure stable water level display detection while allowing staff to conveniently perform inspections.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling readers to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details.
[0026] See also Figures 1 to 8 The utility model provides a water level display device for a fire pool, and the technical solution is as follows:
[0027] The utility model comprises a fire-fighting pool 1, wherein a water inlet pipe 2 is arranged on the top of the fire-fighting pool 1, a water outlet pipe 3 is arranged on the end of the top of the fire-fighting pool 1 away from the water inlet pipe 2, and an overflow pipe 4 is arranged on the side of the fire-fighting pool 1 close to the water outlet pipe 3, a liquid level cylinder 5 is arranged on the end of the fire-fighting pool 1 close to the water outlet pipe 3, a water inlet 6 is opened between the fire-fighting pool 1 and the liquid level cylinder 5, and the water inlet 6 is located at the bottom of the liquid level cylinder 5, a guide rod 7 is arranged in the liquid level cylinder 5, a floating ring 8 is sleeved on the guide rod 7, a plurality of moving rods 9 cooperating with the floating ring 8 are evenly arranged on the left and right sides of the liquid level cylinder 5, the plurality of moving rods 9 are arranged in two longitudinal rows at intervals on the left and right sides of the liquid level cylinder 5, and are opposite to each other, each moving rod 9 extends outside the liquid level cylinder 5, and a reflecting plate 10 is arranged on the end of each moving rod 9 away from the liquid level cylinder 5, two supporting plates 11 are symmetrically arranged on the top of the side of the fire-fighting pool 1 close to the liquid level cylinder 5, and an infrared ranging sensor 12 cooperating with the plurality of reflecting plates 10 is arranged at the bottom of each supporting plate 11, and a reset limiting component is provided on each moving rod 9.
[0028] Fire-fighting water is introduced into the fire-fighting pool 1 through the water inlet pipe 2. During the process, the water in the fire-fighting pool 1 enters the liquid level cylinder 5 through the water inlet 6. As the amount of water entering increases, the floating ring 8 floats on the horizontal plane under the buoyancy of the water, and moves upward along the guide rod 7 following the increase in the amount of water. When passing through the two opposing moving rods 9, the corresponding two moving rods 9 are pushed away from the liquid level cylinder 5, driving the reflective plate 10 on the moving rod 9 to move. At this time, the infrared light emitted by the two infrared ranging sensors 12 above the fire-fighting pool 1 is blocked by the extended reflective plate 10, and the infrared light is reflected back to the infrared ranging sensor 12. After receiving the signal, the infrared ranging sensor 12 passes through the internal The single chip microcomputer processes and calculates the distance between the reflected signal source and the infrared ranging sensor 12, and then the water level of the fire pool 1 at this time can be objectively known. In an environment where it is easily exposed to water, mechanical equipment is used instead of electronic equipment to objectively observe the change of water level and improve the display stability of the water level display device; when the water volume in the fire pool 1 is lower than the specified minimum water level, the water volume in the fire pool 1 is not enough to push the floating ring 8 to touch the lowest moving plate, and the infrared ranging sensor 12 will not receive any signal for a period of time. That is, at this time, the staff can judge based on the infrared ranging sensor 12 that water needs to be added to the fire pool 1 to avoid the situation where there is no water available due to an accident.
[0029] The limiting assembly includes an arc plate 13, a limiting spring 15 and a limiting plate 14. The liquid level cylinder 5 is provided with an arc plate 13, and the arc plate 13 divides the liquid level cylinder 5 into two cavities, namely, an inner cavity and an outer cavity. Each moving rod 9 is provided with a limiting plate 14, and each limiting plate 14 is located in the outer cavity. Each limiting plate 14 is symmetrically provided with two limiting springs 15, and the other end of each limiting spring 15 is connected to the outer side wall of the arc plate 13; each moving rod 9 is connected to the arc plate 13 with a rubber ring; when the floating ring 8 moves to contact the moving rod 9 under the action of water buoyancy, The moving rod 9 drives the reflecting plate 10 to move outside the liquid level cylinder 5, and the limiting plate 14 moves along with it, driving the two limiting springs 15 to extend. When the water volume changes, the floating ring 8 moves away from the moving rod 9, and under the action of the two limiting springs 15, drives the moving rod 9 to retract and return to its original state; in the process of the movement of the moving rod 9, a small amount of water will be driven into the outer cavity through the connection between the moving rod 9 and the arc plate 13. A rubber ring is provided at each connection between the moving rod 9 and the arc plate 13 to reduce the amount of water entering the outer cavity and avoid affecting the operating stability of other parts.
[0030] Two drainage holes are provided on the inner wall of the fire pool 1 on the side close to the liquid level cylinder 5, and a water baffle 16 is installed on each drainage hole through a hinge, and each drainage hole is located at the bottom of the inner and outer cavities of the liquid level cylinder 5; although a rubber ring is provided at the connection between each moving rod 9 and the arc plate 13, there is a gap when the moving rod 9 moves, and a relatively small amount of water still follows and enters the outer cavity, which is easy to fill the outer cavity in the long run, resulting in limiting the stability of the use of other parts such as the spring 15; by providing two drainage holes on the inner wall of the liquid level cylinder 5 and hingedly connecting the water baffle 16 thereto, the water baffle 16 can only be turned inward toward the fire pool 1 When the water level in the fire pool 1 is above the drain outlet, the internal water pressure presses down the water baffle 16, so that the water baffle 16 cannot be turned over to achieve a certain sealing performance; and when the water volume in the fire pool 1 drops and is lower than the drain outlet, the water volume remaining in the outer cavity pushes the water baffle 16 open, so that the water remaining in the outer cavity enters the fire pool 1, so as to prevent the remaining water from staying in the outer cavity for too long; when the water level in the fire pool 1 drops sharply, a pressure difference is formed between the outer cavity and the fire pool 1, which will form a certain driving force, and cooperate with the driving force of the water volume in the outer cavity to push the water baffle 16 open, so that water enters the fire pool 1.
[0031] A spiral track 17 is provided on the guide rod 7, and two sliders 18 cooperating with the spiral track 17 are provided on the inner wall of the floating ring 8; the guide rod 7 and the floating ring 8 are soaked in water for a long time, and impurities such as scale are prone to appear in the gap between the two, and then the floating ring 8 is prone to get stuck when moving; a spiral track 17 is provided on the guide rod 7, and two sliders 18 are provided on the inner wall of the floating ring 8 to mesh with the spiral track 17. When the floating ring 8 moves up and down, it will rotate and move along the spiral track 17, thereby breaking up the scale impurities in the gap between the two to avoid getting stuck.
[0032] An annular scraper 19 is provided on each slider 18; the spiral track 17 is soaked in water for a long time, and it is inevitable that impurities will exist in the track. The annular scraper 19 is provided. When the two sliders 18 move on the corresponding spiral track 17, the annular scraper 19 scrapes off the impurities to avoid the accumulation of impurities and affect the stability of the slider 18 on the spiral track 17. Most of the scraped impurities will be separated with the stirred water flow to avoid the accumulation of impurities on the annular scraper 19 and prevent the smoothness of the sliding of the slider 18 from being affected.
[0033] The guide rod 7 and the liquid level cylinder 5 are of separate design, a cylinder cover 20 is provided on the top of the liquid level cylinder 5, a handle 22 is provided on the cylinder cover 20, and the guide rod 7 extends upward to be connected to the bottom of the cylinder cover 20, a fixed ball 21 is provided at the lower end of the guide rod 7, and a quick-release assembly is provided between the cylinder cover 20 and the liquid level cylinder 5; the staff needs to regularly inspect and maintain the detection equipment, and the underground fire water tank is buried under the ground, which increases the difficulty of maintenance. By setting the guide rod 7 and the liquid level cylinder 5 as a separate design, the staff can easily separate the guide rod 7 and the liquid level cylinder 5 through the quick-release assembly, and then grab the handle 22 to take out the cylinder cover 20, the guide rod 7 and the floating ring 8 for maintenance. When the maintenance is completed, they can be installed back, which improves the convenience of maintenance.
[0034] The quick-release assembly includes a slot 23 and a block 24. Two slots 23 are symmetrically arranged at the center of the top of the liquid level cylinder 5, and each slot 23 is L-shaped. Two blocks 24 are symmetrically arranged at the center of the bottom of the cylinder cover 20, and each block 24 is L-shaped to match the slot 23. When installing, it is only necessary to align the block 24 with the slot 23, and then move the cylinder cover 20 downward. When the cylinder cover 20 is supported, grasp the handle 22 and turn it to the right until the block 24 is supported by the inner wall of the slot 23, and the installation of the cylinder cover 20 and the liquid level cylinder 5 is completed. Conversely, when disassembling, it is only necessary to grasp the handle 22 and rotate it to the left, and then lift the cylinder cover 20, which improves the convenience of disassembly and assembly between the cylinder cover 20 and the liquid level cylinder 5.
[0035] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
