Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage test sampler. Background Art

[0002] As we all know, sewage refers to water that has been used in life or production and has been polluted to a certain extent, losing its original function, so it is simply called sewage. Sewage can be roughly divided into four categories: industrial wastewater, domestic sewage, commercial sewage, and surface runoff. Testers need to use sewage test samplers to collect sewage.

[0003] In real life, most of the sewage samplers sold on the market are divided into automatic and manual types. After taking the sewage, the sewage is poured into the sampling bottle, but the length of the sampling tube is limited, and random sampling is required when sampling sewage, but it is not convenient to collect sewage in a distant river, and it is generally extended by an electric telescopic rod and other devices to drive the sampling bottle into the distant river, but the electric telescopic rod itself has a limited extension length and a slow extension speed, and the sampling bottle cannot be thrown into the river quickly, which has certain limitations. Secondly, the existing sewage detection samplers can only take out sewage samples from one location at a time, and cannot perform sampling at all depths of sewage at the same time. Therefore, the practicality is not very good, and there is still room for improvement. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a sewage test sampler, which has the characteristic of improving practicability.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage test sampler, comprising a sampling bottle and a casting rod, the right front portion of the casting rod is rotatably connected to a rotating disk via a rotating shaft and is wound with a wire, the other end of the wire is connected to the upper portion of the sampling bottle, a load-bearing block is provided at the lower portion of the sampling bottle, a plurality of water inlets are provided at the rear portion of the sampling bottle, a plurality of support plates are provided at the rear portion of the sampling bottle, and all of them are rotatably connected to a baffle via a rotating shaft, a plurality of support plates are provided in the sampling bottle, a plurality of lifting plates are slidably connected between the plurality of support plates, a plurality of limiting plates are provided on the upper portions of the plurality of lifting plates, and the rear end surfaces of the plurality of limiting plates are in contact with the front end surfaces of the corresponding baffles.

[0008] Furthermore, the rear end faces of several of the baffles coincide with the corresponding water inlets, the lengths and widths of several of the baffles are greater than the lengths and widths of the water inlets, the rear of the sampling bottle is provided with several grooves, and several springs are provided, and the fronts of several of the springs are connected to the rear of the baffle.

[0009] Furthermore, the plurality of lifting plates are made of lightweight plastic, and gaps are arranged between the four side surfaces of the plurality of lifting plates and the inner wall of the sampling bottle.

[0010] Furthermore, a plurality of drain pipes are connected through the front of the sampling bottle, and the front of the plurality of drain pipes are all threadedly connected with covers.

[0011] Preferably, a conduit is provided at the right portion of the casting rod, the line and the conduit are arranged through-through, and a handle is provided at the front portion of the casting rod.

[0012] Preferably, a connecting rod is provided on the right portion of the rotating disk.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a sewage test sampler, which has the following beneficial effects:

[0015] For the sewage test sampler, the staff grasps the handle of the casting rod and swings the casting rod to quickly throw the sampling bottle into the distant river to collect sewage. The throwing distance is farther than the length of the electric telescopic rod, and the throwing speed is faster than the extension speed of the electric telescopic rod, thus reducing certain limitations. Secondly, the sampling bottle is driven downward by the load-bearing block, and the pressure difference between the inside and outside of the sampling bottle can make the water push open the baffle and enter the sampling bottle for collection. By the time when the sewage enters the sampling bottle, the baffles in different positions can be pushed open, and the sampling bottle can be controlled to collect sewage at different depths, thereby improving certain practicality.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6The utility model is a sewage test sampler, comprising a sampling bottle 1 and a casting rod 2. The right front part of the casting rod 2 is connected to a rotating disk 3 through a rotating shaft, and is wound with a line 4. The other end of the line 4 is connected to the upper part of the sampling bottle 1. A connecting rod is provided on the right side of the rotating disk 3. The staff grabs the casting rod 2 and then throws the sampling bottle 1 into a river in the distance. The connecting rod is grabbed and then rotated to drive the rotating disk 3 to rotate and collect the line 4 and the sampling bottle 1. A catheter 13 is provided on the right side of the casting rod 2. The line 4 and the catheter 13 are arranged to penetrate. The line 4 moves in the catheter 13, which is convenient for the staff to throw the sampling bottle 1. A handle 14 is provided on the front part of the casting rod 2. The staff grabs the handle 14 and can cast the casting rod 2. The line throwing 4 action is performed, and a load-bearing block 5 is provided at the lower part of the sampling bottle 1. The load-bearing block 5 can make the sampling bottle 1 vertically penetrate into the river. Several water inlets 6 are provided at the rear part of the sampling bottle 1. Several support plates 7 are provided at the rear part of the sampling bottle 1, and they are all connected with baffles 8 through rotation of the rotating shaft. The sampling bottle 1 enters the river, and the baffle 8 on the side of the water inlet 6 below is pushed open, and the water in the river enters the sampling bottle 1 through the water inlet 6. As the sampling bottle 1 sinks into the water, water continues to enter the sampling bottle 1. The rear end faces of several baffles 8 are overlapped with the corresponding water inlet 6, so that the baffles 8 can cover the water inlet 6. The length and width of several baffles 8 are greater than the length and width of the water inlet 6, so that the baffles 8 can cover the water inlet 6. The sampling bottle 1 is provided with a water inlet 6, and the rear part thereof is provided with several grooves, and each of them is provided with several springs, and the front parts of the several springs are connected with the rear part of the baffle 8. When the water inside the sampling bottle 1 is full, the pressure difference between the inside and the outside is in a balanced state, and the spring pulls the baffle 8 to fit on the side wall of the sampling bottle 1, covering the water inlet 6. The sampling bottle 1 is provided with several supporting plates 9, and the several supporting plates 9 are slidably connected with a lifting plate 10. The river water enters the sampling bottle 1 through the lower water inlet 6, and then the lower lifting plate 10 is lifted up. The several lifting plates 10 are made of lightweight plastic, which is convenient for the sampling bottle 1 to be lifted by water, and the surrounding end faces of the several lifting plates 10 are provided with gaps between the inner wall of the sampling bottle 1, reducing Due to the friction between the small lifting plate 10 and the sampling bottle 1, the upper parts of several lifting plates 10 are provided with limiting plates 11, and the rear end faces of several limiting plates 11 are in contact with the front end faces of the corresponding baffles 8. When the lower lifting plate 10 and limiting plates 11 are lifted by water and the lifting plate 10 and the supporting plate 9 above it are in contact with each other, the limiting plates 11 leave the baffle 8 in the middle. Under the condition of internal and external pressure difference, the baffle 8 is pushed open by water, and the river water enters the sampling bottle 1, and finally the upper lifting plate 10 and limiting plates 11 are lifted up. The front part of the sampling bottle 1 is penetrated by several drain pipes 12, and the front parts of several drain pipes 12 are threadedly connected with covers. After unscrewing the covers, the collected water can be taken out through the drain pipes 12.

[0025] In summary, when the sewage test sampler is in use, the staff grabs the casting rod 2 and then swings it to throw the sampling bottle 1 into the river. Under the action of the load-bearing block 5, the sampling bottle 1 enters the river, and the water inlet 6 located at the lower part enters the river. Under the pressure difference between the inside and the outside, the river water pushes the baffle 8 open and flows into the sampling bottle 1. As the sampling bottle 1 sinks downward, the sampling bottle 1 at the water inlet 6 is filled with water, and the lifting plate 10 and the limit plate 11 are lifted up. When the upper end surface of the lifting plate 10 fits with the lower end surface of the supporting plate 9 above it, the limit plate 11 on the upper part of the lifting plate 10 leaves the baffle 8 that is pushed up. , then the baffle 8 located in the middle is pushed open by water, and water enters the sampling bottle 1. After the internal and external pressure difference of the sampling bottle 1 located at the lower part is balanced, the spring located at the lower opening contracts, pulls the baffle 8 back, and fits it on the side wall of the sampling bottle 1. In the same way, the baffle 8 located at the upper water inlet 6 is pushed open by water, and then enters the sampling bottle 1. When the sampling is completed, the staff grabs the connecting rod on the rotating disk 3 and rotates it, driving the rotating disk 3 to rotate, and retracts the line 4 and the sampling bottle 1. Then the staff unscrews the cover on one side of the drain pipe 12 and drains the water in the sampling bottle 1 through the drain pipe 12.
