Description

Technical Field

[0001] The utility model relates to a collector, in particular to a blockage-proof water sample collector which is easy to clean. Background Art

[0002] Water quality assessment is part of environmental assessment, and water samples need to be collected before water quality assessment. In some rivers, reservoirs, lakes and other water bodies, there may be debris such as aquatic plants and plastic bags. When collecting water samples, the existing water sample collectors will be blocked by aquatic plants, plastic bags, etc., which greatly reduces the water collection efficiency.

[0003] The existing collector needs to be taken out of the water and then the debris at the water collection port needs to be manually cleaned. Water samples sometimes need to be collected at the same point. It is difficult to put the collector back to its original place after it is taken out of the water. If the debris is not removed, the water collection efficiency will be greatly reduced. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-blocking water sample collector which is easy to clean, so as to solve the technical problem that after the water collection port of the existing water sample collector is blocked by debris, the blocked water collection port cannot be cleaned underwater.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a water sample collector that is easy to clean and prevents blocking, including a collector cylinder, a piston, a first filter screen, a second filter screen, a first clamping rod and a second clamping rod;

[0006] The collector cylinder is a hollow cylindrical structure, a first filter screen is arranged in the collector cylinder, a piston is inserted in the collector cylinder, a push rod is arranged at one end of the piston, and the push rod extends to the outside of the collector cylinder;

[0007] The bottom surface of the collector cylinder away from the push rod is abutted with a second filter screen, the second filter screen completely covers the bottom surface of the collector cylinder, the second filter screen is fixedly connected to the first clamping rod, and the second filter screen is detachably connected to the second clamping rod;

[0008] The first clamping rod and the second clamping rod are both hinged to the outer side wall of the collector barrel.

[0009] As a preferred solution, the first clamp rod and the second clamp rod are symmetrically arranged on both sides of the collector cylinder, and the ends of the first clamp rod and the second clamp rod close to the second filter are bent toward the collector cylinder, and the ends of the first clamp rod and the second clamp rod away from the second filter are bent toward the ends away from the collector cylinder.

[0010] As a preferred solution, a support frame is symmetrically provided on the outer side wall of the collector cylinder, and the support frame is hinged to the first clamping rod or the second clamping rod.

[0011] As a preferred solution, the support frame is further provided with a mounting groove, which extends axially along the collector barrel, and an arc-shaped elastic plate is provided in the mounting groove, which abuts against the first clamping rod or the second clamping rod.

[0012] The beneficial effects of the utility model are:

[0013] The utility model is provided with a first filter screen and a second filter screen, wherein the first filter screen is an inner screen and the second filter screen is an outer screen, and weeds, plastics and other debris will be intercepted by the second filter screen.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] like Figure 1-Figure 4As shown, the utility model discloses a water sample collector that is easy to clean and prevents blocking, including a collector barrel 1, a piston 2, a first filter screen 3, a second filter screen 4, a first clamping rod 5 and a second clamping rod 6. The collector barrel 1 is a hollow cylindrical structure, and the collector barrel 1 is provided with a first filter screen 3. As a preferred solution, Figure 4 As shown, the first filter screen 3 is arranged near the bottom of the collector cylinder 1, and the first filter screen 3 is detachably connected to the collector cylinder 1. A piston 2 is inserted into the collector cylinder 1, and a push rod 21 is arranged at one end of the piston 2. When the piston 2 contacts the first filter screen 3, the push rod 21 can extend to the outside of the collector cylinder 1. In order to facilitate the operator to push and pull the push rod 21, a push plate 22 can also be arranged at the rear end of the push rod 21.

[0023] The bottom surface of the collector barrel 1 away from the push rod 21 is abutted against the second filter 4, and the second filter 4 can completely cover the bottom surface of the collector barrel 1. In order to more conveniently keep the second filter 4 away from the collector barrel 1, the diameter of the second filter 4 needs to be larger than the diameter of the collector barrel 1. The second filter 4 is fixedly connected to the first clamp rod 5, and the second filter 4 is detachably connected to the second clamp rod 6. For example, a limiting groove can be set for the second clamp rod 6, and then the second filter 4 is inserted into the limiting groove. As a preferred embodiment, the first clamp rod 5 and the second clamp rod 6 are set on the same diameter of the second filter 4. At this time, the first clamp rod 5 and the second clamp rod 6 are symmetrically distributed on both sides of the collector barrel 1.

[0024] like Figure 2 As shown, the first clamping rod 5 and the second clamping rod 6 are both circular rod-shaped structures. In order to better connect and fix the second filter screen 4, the head of the first clamping rod 5 and the head of the second clamping rod 6 (i.e., the end close to the second filter screen 4) are bent toward the direction close to the collector barrel 1.

[0025] The middle part 5 of the first clamping rod and the middle part of the second clamping rod 6 are hinged to the collector barrel 1. As a hinged connection method, support frames 11 are fixed to the symmetrical sides of the collector barrel 1 respectively, and the support frames 11 are hinged to the first clamping rod 5 or the second clamping rod 6. The tail of the first clamping rod 5 and the tail of the second clamping rod 6 are bent away from the collector barrel 1.

[0026] In order to facilitate the rebound of the first clamping rod 5 and the second clamping rod 6 after being pinched by the operator, an installation groove 111 can also be provided on the support frame 11. The installation groove 111 extends axially along the collector barrel 1. An arc-shaped elastic plate 7 is provided in the installation groove 111. The arc-shaped elastic plate 7 is made of elastic material and abuts against the first clamping rod 5 or the second clamping rod 6.

[0027] When in use, push the piston 2 to the second filter screen 4, place the collector cylinder 1 into the water, pull the push rod 21, and water will enter the collector cylinder 1. When the push rod 21 is difficult to pull, the operator holds the collector cylinder 1 with one hand, and pinches the first clamping rod 5 and the second clamping rod 6 with the other hand at the same time, and then moves the tail of the first clamping rod 5 and the tail of the second clamping rod 6 in the direction close to the collector cylinder 1, and the first clamping rod 5 drives the second filter screen 4 to move, and the arc-shaped elastic plate 7 is deformed by force. Then let go, the arc-shaped elastic plate 7 recovers and drives the first clamping rod 5 and the second clamping rod 6 to reset. Pull the first clamping rod 5 several times, and the second filter screen 4 reciprocates in the water. Under the action of the water flow, the debris covering the second filter screen 4 is separated from the second filter screen 4. Obviously, only the first clamping rod 5 can be controlled during the above operation, but only controlling the first clamping rod 5 is likely to cause the collector cylinder 1 to shake, causing the collector cylinder 1 to deviate from the collection point.

[0028] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
